    To study the factors influencing happiness of grandmothers raising grandchildren in the rural areas of Northern Thailand. Cross-sectional survey research was conducted among 400 grandmothers, aged 50-79 years, who raised their grandchildren in the rural areas of Northern Thailand. Participants were selected by cluster sampling. Data were collected through a structured interview from April to July 2009 and analyzed by frequency, percentage, Pearson product moment correlation coefficient, and Multiple regression analysis. Nearly half (46.8%) of grandmothers raising grandchildren had high level of happiness, followed by moderate level (40.4%) and low level (12.8%). The factors, which significantly influenced the happiness of the grandmothers, were self-esteem, social support, and family relationships (p-value happiness of the grandmothers by 48.1%. Self-esteem had the highest predictive power of happiness among grandmothers. The factors influencing happiness of grandmothers raising grandchildren were self-esteem, social support, and family relationships. To promote happiness of grandmothers, responsible organizations should establish activities that enhance the grandmother's self-esteem, provide sufficient social support, and promote good family relationships.

    The purpose of this study was to test the relationship between Buddhist religious practices and blood pressure. A cross-sectional survey of Buddhist religious practices and blood pressure was conducted with 160 Buddhist elderly in rural Uttaradit, northern Thailand. After controlling for the variables of gender, status, education, salary, underlying hypertension, exercise, salt intake, and taking antihypertensive medications, it was found that lower systolic and diastolic blood pressure is associated with the Buddhist religious practice of temple attendance. The Buddhist older people who regularly attended a temple every Buddhist Holy day (which occurs once a week) were found to have systolic and diastolic blood pressure readings lower than people who did not attend as regularly. It is recommended that nurses advocate for temple attendance in the care protocols for older Buddhist hypertensive patients both in Thailand and internationally. © 2013 Wiley Publishing Asia Pty Ltd.

    Introduction: The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. Methods and findings: This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1...

  4. Power games: The political use of solar technology in northern Thailand

    Science.gov (United States)

    Green, Donna Lisa

    This dissertation politicises and historically situates the transfer of an environmental technology to a less developed country, a transfer that has occurred under the rubric of sustainable development. The case study explores the social and political context of two solar battery charging station programmes selected to provide electrification in rural Northern Thailand beginning in the 1980s. It places these rural electrification programmes in the context of previous rural electrification policies in northern Thailand in the 1960s and 1970s which were driven by an explicitly state-serving agenda: an agenda that aimed to expand the centralised state's ability to pacify and control remote areas of the country. However, it is clear that the technology and implementation strategies selected for the new electrification programmes could not fulfil their community-serving objectives; furthermore, these systems could not meet the actual energy needs of the programmes' intended beneficiaries. I argue that we need to consider whether the objectives that motivated previous rural electrification programmes may be continuing to play a role in the promotion of these new rural electrification programmes, a motivation that would contradict the philosophy behind the choice of the solar battery charging stations. Specifically, I show how the new rural electrification strategy has been de-politicised through its framing within the sustainable development discourses. This thesis highlights how the rush to promote environmental technologies through the rubric of sustainable development may limit a proper consideration of the social and political dynamics that motivated these decisions, resulting in the uncritical justification of technology selection. Scholars have critiqued the social ramifications of, and the political motivations behind, earlier technocentric rural development strategies, showing how they can exacerbate social inequalities. I argue that in this situation, the

    There have been no reports for the frequency of Hb Q-Thailand [alpha 74(EF3)Asp --> His, GAC > CAC] and its combinations either with other forms of thalassemia or hemoglobinopathies in Northern Thailand. The aims of this study were to search for Hb Q-Thailand and its combinations in Northern Thai population and to analyze fractions of hemoglobin in Hb Q-Thailand and its combinations on high performance liquid chromatography (HPLC) chromatograms and/or capillary electrophoresis (CE) electrophoregrams. Blood samples from public and private hospitals in 7 northern provinces of Thailand were analyzed for thalassemia and hemoglobinopathy diagnoses using HPLC and/or CE and DNA analysis techniques at the Thalassemia Laboratory, Associated Medical Sciences Clinical Service Center, Chiang Mai, Thailand. Hb Q-Thailand was found in 13 of 13,596 (0.10%) samples; 6 were heterozygous Hb Q-Thailand, 4 were compound Hb Q-Thailand/alpha-thalassemia-1 Southeast Asian (SEA) type deletion and 3 with combinations of Hb Q-Thailand/beta(0)-thalassemia, Hb Q-Thailand/Hb E and Hb Q-Thailand/Hb E/alpha-thalassemia-1 SEA type deletion. The fractions of hemoglobin on HPLC chromatograms and CE electrophoregrams were observed based on types of combinations. Hb Q-Thailand and its combinations could be found in northern Thai population with the frequency of 0.10%. Thus, the better understanding of HPLC chromatogram and/or CE electrophoregram patterns of Hb Q-Thailand and its combination is essential for diagnosis and genetic counseling of thalassemia and hemoglobinopathies in this area.

    To examine women's embodied knowledge of pregnancy and birth, women's explanations of precautions during pregnancy and birth and preparations for easy birth and the role of a traditional midwife in a Thai birthing care. In-depth interviews relating to traditional and changed beliefs and practices of pregnancy and childbirth with Thai women in Northern Thailand. Chiang Mai city and Mae On sub-district in Chiang Mai province, Northern Thailand. 30 Thai women living in Chiang Mai in Thailand. The social meaning of childbirth in Thai culture is part of the larger social system, which involves the woman, her family, the community, society and the supernatural world. Traditional beliefs and practices in Thai culture clearly aim to preserve the life and well-being of a new mother and her baby. It seems that traditional childbirth practices have not totally disappeared in northern Thailand, but have gradually diminished. Women's social backgrounds influence traditional beliefs and practices. The traditions are followed by most rural and some urban poor women in Chiang Mai. The findings of this study may assist health professionals to better understand women from different cultures. It is important to recognise many factors discussed in this paper within the context of Thai lives and traditions. This will prevent misunderstanding and, consequently, encourage more sensitive pregnancy and birthing care for pregnant women.

  7. The practice of 'Dr' Paep: continuity and change in indigenous healing in northern Thailand.

    Science.gov (United States)

    Weisberg, D H

    1984-01-01

    Dr. Paep Plienphleng is an indigenous curer in a rural district in Chiang Mai Province, Northern Thailand, where he is numbered among the group of healers known as mqq mueang ('Northern doctors'). He specializes in curing saan or 'tumors' by combining several techniques: indigenous surgery, herbal curing and supernatural curing. Other aspects of Dr Paep's practice have been due to larger trends in indigenous healing that have affected him and other curers over past decades. This paper describes the practice of Dr Paep and some aspects of his healing, and examines the context of his practice by exploring other categories of indigenous healers found in this area of the North. It is concluded that Northern Thai healing is undergoing a transformation from a stress on general healing to an emphasis on the use of supernatural cures, more specialization among healers and efforts to adapt services to fit the plural system of care found in this rural Northern Thai environment. Thus, we find the skills of indigenous healers and the nature of indigenous Northern Thai medicine allow for creative adaptation to a changing medical environment.

  8. Thailand: poverty, bright lights, dark alleys.

    Some rural farmers in northern Thailand earn as little as 500 Bahts (US$20) per month, while a factory worker earns an average of 3500 Bahts (US$140) and a private sector executive up to 200,000 Bahts (US$8000) per month. Millions of rural poor individuals in Thailand and elsewhere in Asia are flocking to urban centers in search of survival and better lives. Many, however, wind up working as prostitutes. More than one million children work as prostitutes in Asia, with possibly as many as 200,000 in Thailand alone. These men, women, boys, and girls are at high risk of contracting HIV. An estimated 2.5 million Asians have tested seropositive for infection with HIV, and the World Health Organization estimates that by the year 2000, one-third of the projected HIV cases worldwide will be in Asia, with India and Thailand taking the lead. Existing social services cannot handle the current influx of rural poor to urban areas. In the process, huge tracts of agricultural land are being abandoned, levels of rural and urban poverty are increasing, the extent of homelessness is increasing, and the gap between urban and rural areas grows wider. Thailand has the most inequitable distribution of wealth on the Asian continent.

    This paper examines the transformation of Shan Buddhism in the border area of Northern Thailand. Shan and other ethnic groups have a long history of migration between Northern Thailand and the Shan State of Myanmar; the migration continued even after the border was demarcated at the end of the nineteenth century. Recently, the migration has become unidirectional--from Myanmar to Thailand-- and the number of migrants is growing steadily. An anomalous situation exists in this area: a fluid bord...

  10. Turning Red Rural Landscapes Yellow? Sufficiency Economy and Royal Projects in the Hills of Nan Province, Northern Thailand

    Full Text Available This paper discusses the efforts of the royal family to moralise the environmental behaviour of their subjects in the name of the Sufficiency Economy philosophy solicited by King Bhumibol since the 1990s in Thailand. Drawing on ethnographic fieldwork conducted in Nan province, Northern Thailand, in 2008 and 2009, I focus particularly on Royal Projects recently promoted to correct the rural practices of the ethnic minority groups living in the hills of Nan. In the past, many of these ethnic groups took part in the Maoist insurgency while at present, they represent a key basin of support- ers for the reformist Red Shirts movement which is currently threatening the role of the monarchy in Thai politics. The research suggests that the recently increased trend of staging new projects for sustainable agro-forestry management in a ‘red’ area as Nan does not only aim at improving the conditions of mountain peoples and of the environment, but simultaneously increases the political influence of the conservative forces over this ‘ungovernable’ territory in times of political crisis. ----- Dieser Artikel diskutiert die Bemühungen der königlichen Familie in Thailand seit den 1990-er Jahren, das Umweltverhalten ihrer Subjekte im Namen der Sufficiency Economy Philosophie von König Bhumibol zu moralisieren. Mit Bezug auf ethnografische Forschung in der Provinz Nan in Nordthailand in den Jahren 2008 und 2009 fokussiere ich insbesondere auf Royal Projects, die in letzter Zeit gefördert werden, um ländliche Praktiken ethnischer Minderheiten in den Bergen von Nan zu korrigieren. In der Vergangenheit waren viele dieser ethnischen Gruppen am maoistischen Aufstand beteiligt, während sie heute ein zentrales Auffangbecken für UnterstützerInnen der reformistischen Rothemden, die derzeit die Rolle der Monarchie in der thailändischen Politik in Frage stellen, darstellen.

    Full Text Available This research focuses on urban haze in Upper Northern Thailand (UNT, where smoke haze often produce impacts on human health, tourism, and transportation. The objective was to better understand how the public sector responded to the haze impacts in policy review interviews and analyses of compiled haze-related data during 2007-2011. Moreover, integration of haze adaptation policy and coherency was also explored. The results revealed that Thailand has mainly implemented three National Haze Action Plans since 1997, together with laws and regulations for haze management. Further examination of haze policy at all levels of governance disclosed only vertical integration, whereas cross-boundary integration was reported only with the data and budget. Practically, manpower and function have not yet brought satisfactory outcomes. Moreover, the extent of state responses has been centralized –not decentralized from their centralized political structure. Low participation of people living in both urban and rural areas and cooperative efforts were identified as the main factors contributing to failures in combating smoke haze. Therefore, individuals are of utmost importance for effective solutions. There is a continuous need for prevention campaigns to enhance local people's understanding and participation as well as local communities' networking for solutions to the haze problem.

    The potential of macaque Macaca nemestrina leonina in Thailand to be infected by endemic arboviruses was assessed. The prevalence of antibodies of three arboviruses actively circulating in Thailand was determined by Plaque Reduction Neutralization assay procedures using samples from captive colonies in Northern Thailand. Out of 38 macaques, 9 (24%) presented reacting antibodies against dengue virus, 5 (13%) against Japanese encephalitis virus, and 4 (10%) against Chikungunya virus. Our results indicate that the northern pig-tailed macaque in Thailand can be infected by these arboviruses, inferring therefore that their virus specific vectors have bitten them. Given that, northern pig-tailed macaque represents an abundant population, living in close range to human or in peridomestic setting, they could play a role as potential reservoir host for arboviruses circulating in Thailand. © 2013 Wiley Periodicals, Inc.

    Nutritional status among adolescents is an important health indicator. The up-to-date information about nutritional status and food consumption pattern in the remote rural area is required for the effective public health intervention in the rural area of the country. The present study aimed to demonstrate the prevalence of malnutrition, eating behavior and nutritional knowledge among secondary school students in a remote rural area in Thailand. Body weight and height data were collected from 298 secondary school students for nutritional status calculation using the Institute of Nutrition Research, Mahidol University, INMU-Thaigrowth program. Eating behavior and nutritional knowledge were observed by self-administrated questionnaires. The prevalence low height-for-age (instant noodles (64.4%). The prevalence of malnutrition was low among this population. The studied population had a fair knowledge about nutrition. The authoes found that regular consumption of highly commercialized snack products especially salted chips and instant noodles were at a high level in this remote rural area of Thailand. The pattern of nutritional problems in Thailand may have changed in which a public health program for children in rural areas of the country should recognize this transition.

    A personal inhalation exposure and cancer risk assessment of rural residents in Lampang, Thailand, was conducted for the first time. This highlighted important factors that may be associated with the highest areal incidence of lung cancer. Personal exposure of rural residents to polycyclic aromatic hydrocarbons (PAHs) and their nitro-derivatives (NPAHs) through inhalation of fine particulate matter (PM 2.5 ) was investigated in addition to stationary air sampling in an urban area. The personal exposure of the subjects to PM 2.5 ranged from 44.4 to 316 μg/m 3 , and the concentrations of PAHs (4.2-224 ng/m 3 ) and NPAHs (120-1449 pg/m 3 ) were higher than those at the urban site, indicating that personal exposure was affected by microenvironments through individual activities. The smoking behaviors of the rural residents barely affected their exposure to PAHs and NPAHs compared to other sources. The most important factor concerning the exposure of rural populations to PAHs was cooking activity, especially the use of charcoal open fires. The emission sources for rural residents and urban air were evaluated using diagnostic ratios, 1-nitropyrene/pyrene, and benzo[a]pyrene/benzo[ghi]perylene. Their analyses showed a significant contribution to emission from residents' personal activities in addition to the atmospheric environment. Furthermore, the personal inhalation cancer risks for all rural subjects exceeded the USEPA guideline value, suggesting that the residents have a potentially increased cancer risk. The use of open fires showed the highest cancer risk. A reduction in exposure to air pollutants for the residents could potentially be achieved by using clean fuel such as liquid petroleum gas or electricity for daily cooking.

    Electricity, Information and Communication Technologies (ICTs) are very important not only in urban areas but also in rural areas. To provide ICTs service in rural areas, sources of electricity and communication infrastructures must be implemented. Electricity is a major condition due to the fact that all electronic devices needed it in order to power on, so that it is impossible to operate any forms of ICTs in areas where the main national grid line is unavailable. Almost rural areas of Thailand where the main national grid line is unavailable have very good sunlight intensity. Photovoltaic is the most effective renewable energy technologies in those areas for meeting electricity needed in areas that are not connected to the main national grid line. In this paper, the efficiency utilization of photovoltaic as source of electricity for broadband satellite communication systems as well as social and economic impact and quality of life of people in rural areas of Thailand are presented. The results show that most rural communities would be able to universally access to the basic telecommunications services such as internet access and public telephone via satellite communication systems. However, in some field case study, broadband internet access via satellite communication may be unnecessary for some rural communities and the most exactly rural communities needed are electricity for household usage and battery charger.

    Entomopathogenic nematodes (EPNs) of the genera Steinernema and Heterorhabditis are used as biocontrol agents for insect pests. Survey of indigenous EPNs provides not only the diversity aspects but also the contribution in pest management in local areas. The objective of this study was to survey EPNs in upper northern Thailand. Nine hundred seventy soil samples were obtained from 194 sites in upper northern region of Thailand; of these 60 (6.2%) had EPNs in 2 genera: Steinernema (32 isolates) and Heterorhabditis (28 isolates). Most EPNs were isolated from loam with a soil temperature of 24-38°C, a pH of 1.5-7.0 and a soil moisture content of 0.5-6.8%. Molecular identification based on sequencing of a partial region of an internal transcribed spacer was performed for Heterorhabditis and the 28S rDNA for Steinernema. A BLASTN search of known sequence EPNs revealed 24 isolates of S. websteri and one isolate of S. scarabaei were identified; closely related to S. websteri (accession no. JF503100) and S. scarabaei (accession no. AY172023). The Heterorhabditis species identified were: H. indica (11 isolates), H. gerrardi (2 isolates) and Heterorhabditis sp (8 isolates). Phylogenetic analysis revealed 11 isolates of Heterorhabditis were related to H. indica; 2 isolates were related to Heterorhabditis gerrardi and 8 isolates were closely related to Heterorhabditis sp SGmg3. The study results show the genetic diversity of EPNs and describe a new observation of S. scarabaei and H. gerrardi in Thailand. This finding is new and provides important information for further study on using native EPNs in biological control.

    Background & objectives: Alpha-thalassaemias are genetic disorders with high prevalence in northern Thailand. However, common genotypes and current data on the prevalence of α-thalassaemias have not been reported in this region. Therefore, the objective of the present study was to determine the prevalence of α-thalassaemia genotypes in pregnant women in northern Thailand. Methods: Genomic DNA was extracted from blood samples of pregnant women who came to Maharaj Nakorn Chiang Mai University Hospital during July 2009 to 2010. The common deletion and point mutation genotypes of α-thalassaemia were evaluated by gap- polymerase chain reaction (PCR) and PCR with restriction fragment length polymorphism (RFLP). Results: Genotypes of 638 pregnant women were: 409 samples (64.11%) being normal subjects (αα/αα) and 229 samples (35.89%) with α-thalassaemias. These 229 samples could be classified into deletional HbH disease (--SEA/-α3.7) for 18 samples (2.82%); heterozygous α0-thalassaemia --SEA type (--SEA/αα)) for 78 (12.23%); heterozygous α+-thalassaemia - α3.7 type (-α3.7/αα) for 99 (15.52%); homozygous α+-thalassaemia - α3.7 type (-α3.7/- α3.7) for five (0.78%); heterozygous α+-thalassaemia - α4.2 type (-α4.2/αα) for two (0.31%); and heterozygous HbCS (αCSα/αα) for 27 (4.23%) cases. Interpretation & conclusions: The prevalence of α-thalassaemias in pregnant women in northern Thailand was high. This finding supports the implementation of the prevention and control of this common genetic disorder by screening for α-thalassaemia genotypes. PMID:27241645

    Full Text Available Background. Over the last decade, Thailand has experienced an aging population, especially in rural areas. Research finds a strong, positive relationship between good quality housing and health, and this paper assesses the impact and living experience of housing of older people in rural Thailand. Methods. This was a mixed-method study, using data from observations of the physical adequacy of housing, semistructured interviews with key informants, and archival information from health records for 13 households in rural Thailand. Results. There were four main themes, each of which led to health risks for the older people: “lighting and unsafe wires,” “house design and composition,” “maintenance of the house,” and “health care equipment.” The housing was not appropriately designed to accommodate health care equipment or to fully support individual daily activities of older people. Numerous accidents occurred as a direct result of inadequate housing and the majority of houses had insufficient and unsafe lighting, floor surfaces and furniture that created health risks, and toilets or beds that were at an unsuitable height for older people. Conclusion. This paper provides an improved and an important understanding of the housing situation among older people living in rural areas in Thailand.

    Full Text Available As a family physician and medical anthropologist, I have interacted with pregnant women and their families in Minnesota since 1983 and in one Hmong village in Northern Thailand since 1988. In the previous article I describe our recent research about Hmong families’ pregnancy and birth practices in Thailand. In this article, I reflect upon the differences in Minnesota and Thailand, consider what socio-cultural factors may be influencing people’s experiences, and speculate that Minnesota Hmong experiences could be helpful to Thai Hmong.

    This paper examines how reproducing Chineseness has become a source of social suffering through the case study of a group of Yunnan Chinese who escaped Chinese communist rules in the Mainland in 1949 or shortly after and settled in northern Thailand in the 1960s. As self-proclaimed carriers of traditional Chinese culture, they worked arduously to replicate whatever they considered 'authentic' Chinese through a narrow interpretation of the Confucian moral tenets in daily life. The (re)establishment of a patriarchal social order in Thailand - a society with a relatively high level of gender-equality, has inflicted tremendous pain and suffering among women and youth in this reified society. Ethnographic fieldwork, upon which this paper was based, was conducted in Maehong Village, Chiang Mai Province, between 2002 and 2007.

    Three new species of shoot fly, Atherigona Rondani (subgenus Acritochaeta Grimshaw) (Diptera: Muscidae), are described from northern Thailand, based on morphological characteristics of males. Unique features of A. komi sp. n. include a distinct spiral groove on the dorsal aspect of the fore femur and two dark apical wing spots, whereas A. chiangmaiensis sp. n. is recognized by the presence of one large patch on the apical wing spot, appearing as a large and smaller wave-shaped patch, and no distinct pattern on tergites. A. thailandica sp. n. displays a remarkable dark boomerang-shaped patch along the wing margin and fore femur, with two rows of long hairs on the dorsal surface. Male terminalia are also different in the new species, showing distinctive characteristics. This paper also presents five newly recorded species in Thailand; Atherigona maculigera Stein, Atherigona ovatipennis vietnamensis Shinonaga et Thinh, Atherigona pallidipalpis Malloch, Atherigona seticauda Malloch, and Atherigona setitarsus Shinonaga et Thinh. A key is provided for the adult males of Atherigona recorded in Thailand, all belonging to the subgenus Acritochaeta, except for A. soccata Rondani. PMID:22233520

    Full Text Available Opisthorchis viverrini infection is a major public health problem in northern and northeastern Thailand. The chronic infection of O. viverrini is related to cholangiocarcinoma which causes high mortality in endemic areas. Therefore, the diagnosis, treatment, control and prevention of O. viverrini infection are necessary. The morphology of the egg is very similar to that of other species of human liver flukes (Opisthorchis felineus and Clonorchis sinensis as well as that of small intestinal flukes in the family Heterophyidae. Thus, molecular characterization is crucially required to discriminate species of Opisthorchis-like eggs in fecal examination.We aimed to determine the prevalence of O. viverrini infection among villagers living in Sanamchaikate District, Chachoengsao Province, in central Thailand, where O. viverrini infection has previously been reported. A total of 2,609 fecal samples were examined for Opisthorchis-like eggs using microscopic examination. PCR-RFLP analysis of the ITS2 region was used to discriminate Opisthorchis-like eggs. The genetic structure of O. viverrini infection was demonstrated using nucleotide sequencing of cytochrome c oxidase subunit I (cox1 and NADH dehydrogenase subunit 1 (nad1. Testing of evolutionary neutrality of the cox1 and nad1 sequences of O. viverrini was performed using Tajima's D tests and Fu's Fs tests. Moreover, the haplotype networks and phylogenetic trees were constructed to study the relationships of O. viverrini isolated from different endemic areas. A high prevalence of O. viverrini infection is still observed in a rural community of Chachoengsao Province, central Thailand. The overall prevalence of Opisthorchis-like eggs using microscopic examination was 16.8%. PCR-RFLP profiles showed the predominant infection of O. viverrini (9.6% including very low infections of other small intestinal flukes, Haplorchis taichui (0.08% and Euparyphium albuferensis (0.08%.

    Certain species of Phlebotomine sandflies (Diptera: Psychodidae) are vectors of the protozoa which causes leishmaniasis. Sandflies are found breeding in enclosed places like caves. Thailand is a popular tourist destination, including for ecotourism activities like caving, which increases the risk of contact between tourists and sandflies. Surveillance of sandflies is important for monitoring this risk but identification of species based on morphology is challenged by phenotypic plasticity and cryptic diversity. DNA barcodes have been used for the identification of sandflies in Thailand. We collected sandflies using CDC light trap from four tourist caves in Northern Thailand. Female sandflies were provisionally sorted into 13 morphospecies and 19 unidentified specimens. DNA was extracted from the thorax and legs of sandflies and the DNA barcode region of cytochrome c oxidase I mtDNA amplified and sequenced. The specimens were sorted into 22 molecular operational taxonomic units (MOTU) based on the 145 DNA barcodes, which is significantly more than the morphospecies. Several of the taxa thought to be present in multiple caves, based on morphospecies sorting, split into cave-specific MOTU which likely represent cryptic species. Several MOTU reported in an earlier study from Wihan Cave, Thailand, were also found in these caves. This supports the use of DNA barcodes to investigate species diversity of sandflies and their useful role in surveillance of sandflies in Thailand.

    Experiments were carried out in seven test sites on three Quaternary alluvial and terrace deposit basins of northern Thailand, to test the possibility of using airborne equivalent uranium to predict geogenic indoor radon values of the region. The methodology was based on the correlation among soil gas permeability, soil radon concentration and indoor radon, as well as a relationship between soil radon and airborne uranium values. The methodology established works rather well when tested in areas of known indoor radon. Based on the predicted values that were obtained from this method, indoor radon in most areas of alluvial and terrace deposit basins of northern Thailand is less than 44Bq/m{sup 3}. There is no area in these basins where predicted indoor radon exceeds 74Bq/m{sup 3}.

    1999-01-01

    Full Text Available Three species of Asian native honey bees (Apis cerana, A. florea and A. dorsata from northern Vietnam and Thailand were morphologically analyzed fo r investigations on their geographic variations and relations. In Vietnam, samples were collected from feral and managed colonies. In Thailand, the collections were from feral colonies or from field bees on flowers. Morphological analysis was carried out, using measurements common to honeybee taxonomy. Measured characters were done under stereomicroscope with an ocular micrometer. ANOVA program and multivariate statistical analyses were applied for treating the data. Overall, A. cerana populations in northern Vietnam are significantly morphologically different than from those in Thailand. It may be due to their different geographic locations between the Thai and Vietnamese populations of A. cerana. A. florea bees from Vietnam are generally bigger in size than those from Thailand, but the differences are uncertain. In contrast, the body size of A. dorsata populations from Thailand are bigger than t hose from Vietnam. However, these differences are also not significant. It is nece ssary to take further comparative investigations of these bee species from both countries

    This study analyzes the autosomal short tandem repeats (STRs) variation and the presence of Y chromosomal haplogroups from 44 individuals of the Kayah or Red Karen (KA) in Northern Thailand. The results based on autosomal STRs indicated that the KA exhibited closer genetic relatedness to populations from adjacent regions in Southeast Asia (SEA) than populations from Northeast Asia (NEA) and Tibet. Moreover, an admixed origin of the KA forming three population groups was observed: NEA, Southern China, and Northern Thailand. The NEA populations made a minor genetic contribution to the KA, while the rest came from populations speaking Sino-Tibetan (ST) languages from Southern China and Tai-Kadai (TK) speaking groups from Northern Thailand. The presence of six paternal haplogroups, composed of dual haplogroups prevalent in NEA (NO, N, and D1) and SEA (O2 and O3) as well as the intermediate genetic position of the KA between the SEA and NEA also indicated an admixed origin of male KA lineages. Our genetic results thus agree with findings in linguistics that Karenic languages are ST languages that became heavily influenced by TK during their southward spread. A result of the Mongol invasions during the 13th century A.D. is one possible explanation for genetic contribution of NEA to the KA. © 2015 John Wiley & Sons Ltd/University College London.

    This study explores rural elderly preferences for support across a multi-dimensional measure of elderly care needs. Applying a framework developed in the U.S. to Thailand for the first time, five diverse types of support are considered: meal preparation, personal care, transportation, financial support, and emotional support. The emphasis is on preferences for care and not actual care received. The data are from focus group discussions conducted in seven villages in Nang Rong district, northeastern Thailand. Thailand and the study site represent the social and economic conditions faced by many rapidly industrializing places-where there has been a dramatic demographic transition (lowered fertility and substantial out-migration), growing numbers of older persons remaining in rural settings, and limited publically-financed elderly care or market-based elder care available for purchase. For this study, in each village, male and female older persons aged 60 and over participated in the focus group discussions. As part of the discussion, focus group participants were asked to rank their first four preferences by type of support. Male and female older persons' preferences were slightly different for genderized tasks. In addition, social closeness and geographical proximity mattered. Traditional matrilocal residence patterns contributed to the perceptions of the older persons. Neighbors were preferred when kin were not available. Preferences inform strategic choices by older persons given the context of available resources. Understanding preferences and strategic choices among the older persons can help policy makers tailor programs more effectively and efficiently, without jeopardizing elderly well-being.

    Full Text Available Abstract Although chickenpox is a generally mild, self-limited illness of children, it can cause fatal disease in adults. Accumulating reports from tropical countries showed a high prevalence of seronegativity among the adults, implying that varicella diseases could become a heavy burden in tropical countries. However, in the situation of humanitarian emergencies in tropical areas, chickenpox has largely been ignored as a serious communicable disease, due to lack of data regarding varicella mortality and hospital admissions in such a context. This is the first report describing an outbreak of chickenpox in a refugee camp of tropical region. In 2008, we experienced a varicella outbreak in ethnic Lao Hmong refugee camp in Phetchabun Province, northern Thailand. The attack rate was 4.0% (309/7,815 and this caused 3 hospitalizations including one who developed severe varicella pneumonia with respiratory failure. All hospitalizations were exclusively seen in adults, and the proportion of patients ≥15 years old was 13.6% (42/309. Because less exposure to varicella-zoster virus due to low population density has previously been suggested to be one of the reasons behind higher prevalence of susceptible adults in tropics, the influx of displaced people from rural areas to a densely populated asylum might result in many severe adult cases once a varicella outbreak occurs. Control interventions such as vaccination should be considered even in refugee camp, if the confluence of the risk factors present in this situation.

    Digestive system disorders have a substantial effect on worldwide morbidity and mortality rates, including in Thailand, where the majority of the rural areas have a lack of proper sanitation and awareness about disease prevention. This has led to the prevalence of different types of digestive diseases. Karen people in Thailand still use medicinal plants as first aid remedies in treating these diseases. Therefore, this study aimed at documenting the plants used to cure and prevent different types of digestive system disorders by Karen people of Chiang Mai Province, northern Thailand. Ethnomedicinal data were collected from six key informants and 172 non-specialist informants regarding their traditional knowledge of medicinal plants. Quantitative approaches were used to determine Use Value (UV), Informant Consensus Factor (ICF) and Fidelity Level (FL) values. The study revealed that 36 medicinal plant species belonging to 31 genera and 24 families were used to treat digestive system disorders. The most prevalent plant families were Zingiberaceae (6 species), Euphorbiaceae (4 species) and Fabaceae (4 species). Leaves were the most commonly used plant part accounting for 32.6% of the plants, followed by the bark (18.6%). About 60% of the administrations were given orally by potion (60%) and consumption as food was also indicated (14%). The highest ICF values were recorded for carminative disorders, stomachaches, geographic tongue, constipation, appetite stimulants and food poisoning (1.00 each) indicating the best agreement among the informants knowledge of medicinal plants that were used to treat aliments in these categories. The highest fidelity level values were recorded for Punica granatum (100.00), Psidium guajava (95.45), and Gymnopetalum integrifolium (90.91) showing conformity of knowledge on species with the best healing potential. Medicinal plants still play an important role among Karen culture. The present information on these medicinal plants, which have

    The mosquito vector Culex quinquefasciatus is known to be resistant to insecticides worldwide, including Thailand. This study was the first investigation of the insecticide resistance mechanisms, involving metabolic detoxification and target site insensitivity in C. quinquefasciatus from Thailand. Adult females reared from field-caught larvae from six provinces of northern Thailand were determined for resistant status by exposing to 0.05% deltamethrin, 0.75% permethrin and 5% malathion papers using the standard WHO susceptibility test. The overall mortality rates were 45.8%, 11.4% and 80.2%, respectively. A fragment of voltage-gated sodium channel gene was amplified and sequenced to identify the knock down resistance (kdr) mutation. The ace-1 gene mutation was determined by using PCR-RFLP. The L1014F kdr mutation was observed in all populations, but the homozygous mutant F/F1014 genotype was found only in two of the six provinces where the kdr mutation was significantly correlated with deltamethrin resistance. However, none of mosquitoes had the G119S mutation in the ace-1 gene. A laboratory deltamethrin resistant strain, Cq_CM_R, has been established showing a highly resistant level after selection for a few generations. The mutant F1014 allele frequency was significantly increased after one generation of selection. A synergist assay was performed to assess the metabolic detoxifying enzymes. Addition of bis(4-nitrophenyl)-phosphate (BNPP) and diethyl maleate (DEM), inhibitors of esterases and glutathione S-transferases (GST), respectively, into the larval bioassay of the Cq_CM strain with deltamethrin showed no significant reduction. By contrast, addition of piperonyl butoxide (PBO), an inhibitor of cytochrome P450 monooxygenases, showed a 9-fold reduction of resistance. Resistance to pyrethroids in C. quinquefasciatus is widely distributed in northern Thailand. This study reports for the first time for the detection of the L1014F kdr mutation in wild populations

  2. Forest, water and people: The roles and limits of mediation in transforming watershed conflict in Northern Thailand

    Full Text Available This study focuses on watershed management in Northern Thailand, where conflict over forest, land and water-use is a prevailing problem. A characteristic of watershed conflicts is that they are often multifaceted and involve multiple stakeholders with different interests and values, consequently requiring conflict management approaches that are sustainable in their outcomes, including addressing the underlying causes of the conflicts. Drawing from a case study in Mae Tia Mae Tae watershed in Northern Thailand, this study explores how mediation by external third party can contribute to the transformation of conflicts in the watershed and how the broader institutional contexts in which the conflict is embedded shapes the mediation outcomes. The study suggests that co-creation of mutual understanding and recognition of each party’s socio-cultural differences, including land-use practices, are critical in building trust and in how conflict transformation processes moved forward. Moreover, the ability of the mediator in facilitating the establishment of a deliberative institution (i.e. a watershed network committee and agreed rules on forest utilization were also critical in maintaining long-term collaboration in the watershed and potentially preventing other conflicts arising in the future. Some issues, however, may threaten the continuity of the cooperation and sustainability of peace in the watershed, including the lack of structural reform that formally recognizes local people’s rights, insecure land tenure, and the absence of legal recognition for the watershed network committee as a legitimate mechanism for watershed decision making. The paper discusses these findings by comparing it with those from our previous studies in other locations (Cambodia, Indonesia and Western Thailand to strengthen the insights from Northern Thailand. Finally, the research puts forward some recommendations for reforms and to strengthen the use of effective

    Beef cattle production represents the largest cattle population in Thailand. Their productivity is constrained by tick-borne diseases such as babesiosis and theileriosis. In this study, we determined the prevalence of Babesia bigemina, Babesia bovis and Theileria orientalis using polymerase chain reaction (PCR). The genetic markers that were used for detection of the above parasites were sequenced to determine identities and similarity for Babesia spp. and genetic diversity of T. orientalis. Furthermore the risk factors for the occurrence of the above protozoan parasites in beef cattle from northern and northeastern parts of Thailand were assessed. A total of 329 blood samples were collected from beef cattle in 6 provinces. The study revealed that T. orientalis was the most prevalent (30.1%) parasite in beef cattle followed by B. bigemina (13.1%) and B. bovis (5.5%). Overall, 78.7% of the cattle screened were infected with at least one of the above parasites. Co-infection with Babesia spp. and T. orientalis was 30.1%. B. bigemina and T. orientalis were the most prevalent (15.1%) co-infection although triple infection with the three parasites was observed in 3.0% of the samples. Sequencing analysis revealed that B. bigemina RAP1 gene and B. bovis SBP2 gene were conserved among the parasites from different cattle samples. Phylogenetic analysis showed that the T. orientalis MPSP gene from parasites isolated from cattle in north and northeast Thailand was classified into types 5 and 7 as reported previously. Lack of tick control program was the universal risk factor of the occurrence of Babesia spp. and T. orientalis infection in beef cattle in northern and northeastern Thailand. We therefore recommend training of farmers on appropriate tick control strategies and further research on potential vectors for T. orientalis and elucidate the effect of co-infection with Babesia spp. on the pathogenicity of T. orientalis infection on beef in northern and northeastern Thailand

    High-resolution melting (HRM) analysis is a rapid mutation analysis which assesses the pattern of reduction of fluorescence signal after subjecting the amplified PCR product with saturated fluorescence dye to an increasing temperature. We used HRM analysis for prenatal diagnosis of beta-thalassemia disease in northern Thailand. Five PCR-HRM protocols were used to detect point mutations in five different segments of the beta-globin gene, and one protocol to detect the 3.4 kb beta-globin deletion. We sought to characterize the mutations in carriers and to enable prenatal diagnosis in 126 couples at risk of having a fetus with beta-thalassemia disease. The protocols identified 18 common mutations causing beta-thalassemia, including the rare codon 132 (A-T) mutation. Each mutation showed a specific HRM pattern and all results were in concordance with those from direct DNA sequencing or gap-PCR methods. In cases of beta-thalassemia disease resulting from homozygosity for a mutation or compound heterozygosity for two mutations on the same amplified segment, the HRM patterns were different to those of a single mutation and were specific for each combination. HRM analysis is a simple and useful method for mutation identification in beta-thalassemia carriers and prenatal diagnosis of beta-thalassemia in northern Thailand.

    In this present study, the serotype of 40 Streptococcus suis isolates from submaxillary glands of pig carcasses sold in wet markets in Chiang Mai Province, northern Thailand, was investigated. Eleven serotypes, including types 2, 3, 4, 5, 7, 8, 9, 17, 21, 22 and 31, were found in the isolates by a Multiplex PCR combined with serum agglutination. Of the eleven serotypes present, type 3 was the most prevalent, while types 2, 4, 5 and 21 were of primary interest due to their human isolate serotype. The mrp+/epf - /sly - genotype was found to be the most prevalent genotype. This study indicates the importance of effective control of human S. suis infection due to raw pork or pig carcass handling in northern Thailand.

We aimed to establish the time of highest death risk during TB treatment, and to identify the risk factors taking place during that period of high risk.Patients and methods: We explored the TB surveillance data of the Chiang Rai province, Northern Thailand, retrospectively for 12 years. A total of 19,174 TB patients (including 5,009 deaths were investigated from 1997 to 2008, and the proportion of deaths in each month of TB treatment was compared. Furthermore, multiple logistic regression analysis was performed to identify the characteristics of patients who died in the first month of TB treatment. A total of 5,626 TB patients from 2005 to 2008 were included in this regression analysis.Result: The numbers of deaths in the first month of TB treatment were 38%, 39%, and 46% in the years 1997–2000, 2001–2004, and 2005–2008, respectively. The first month of TB treatment is the time of the maximum number of deaths. Moreover, advancing age, HIV infection, and being a Thai citizen were significant factors contributing to these earlier deaths in the course of TB treatment.Conclusion: Our findings have pointed to the specific time period and

    The emergence of rural health insurance plays a crucial role in alleviating the pressure on rural medical expenditure. Under the current medical system in northern China, rural medical insurance may reduce the free referral of patients with chronic diseases among hospitals. This study was carried out based on the results of an investigation of rural chronically-ill patients in eight county hospitals in northern China, as well as through the comparison and analysis of patients with chronic diseases, considering whether they were with or without rural health insurance. The main results showed that both age ( χ 2 = 22.9, p rural peoples' willingness to buy health insurance. Meanwhile, both the quality of the hospital's treatment ( B = 0.555, p rural health insurance had weakened the three relationships upon which the aforementioned correlations were based.

    Full Text Available Abstract Background Circumstances surrounding injection initiation have not been well addressed in many developing country contexts. This study aimed to identify demographic factors, sexual behaviors and drug use characteristics related to injection initiation among drug users in northern Thailand. Methods A cross-sectional survey was conducted among 2,231 drug users admitted to the Northern Drug Treatment Center in Mae Rim, Chiang Mai, Thailand, between February 1, 1999 and December 31, 2000. A multiple logistic regression was employed to identify the independent effects from potential risk factors of transition into injection. Results After controlling for other covariates, being 20 years of age or older, single, ever receiving education, urban residence, and having a history of smoking or incarceration were significantly associated with higher likelihood of injection initiation. Multiple sex partners and an experience of sex abuse were associated with an increased risk of injection initiation. Comparing to those whose first drug was opium, individuals using heroin as their initiation drug had greater risk of injection initiation; conversely, those taking amphetamine as their first drug had less risk of injection initiation. Age of drug initiation was negatively associated with the risk of injection initiation: the older the age of drug initiation, the less the risk of injection initiation. Conclusion Injection initiation was related to several demographic factors, sexual behaviors and drug use characteristics. Understanding these factors will benefit the design of approaches to successfully prevent or delay transition into injection.

    Despite the existence of effective anthelmintics, parasitic infections remain a major public health problem in Southeast Asia, including Thailand. In rural communities, continuing infection is often reinforced by dietary habits that have a strong cultural basis and by poor personal hygiene and sanitation. This study presents a survey of the prevalence of intestinal parasitic infections among the people in rural Thailand. The community-based cross-sectional study was conducted in villages in Khon Kaen Province, northeastern Thailand, from March to August 2013. A total of 253 stool samples from 102 males and 140 females, aged 2-80 years, were prepared using formalin-ethyl acetate concentration methods and examined using light microscopy. Ninety-four individuals (37.2%) were infected with 1 or more parasite species. Presence of parasitic infection was significantly correlated with gender (P=0.001); nearly half of males in this survey (49.0%) were infected. Older people had a higher prevalence than younger members of the population. The most common parasite found was Opisthorchis viverrini (26.9%), followed by Strongyloides stercoralis (9.5%), Taenia spp. (1.6%), echinostomes (0.4%), and hookworms (0.4%). The prevalence of intestinal protozoa was Blastocystis hominis 1.6%, Entamoeba histolytica 0.8%, Entamoeba coli 0.8%, Balantidium coli 0.4%, Iodamoeba bütschlii 0.4%, and Sarcocystis hominis 0.4%. Co-infections of various helminths and protozoa were present in 15.9% of the people. The present results show that the prevalence of parasitic infections in this region is still high. Proactive education about dietary habits, personal hygiene, and sanitation should be provided to the people in this community to reduce the prevalence of intestinal parasite infections. Moreover, development of policies and programs to control parasites is needed.

    An investigation into the concentrations of the main heat producing radioactive elements, uranium, thorium and potassium in various rock samples was carried out by gamma ray spectrometry. The samples included igneous, metamorphic and sedimentary rocks of different ages. They were collected mainly from the northern part of the country. Results of the investigation show relatively high concentrations of radioactive elements in most rock types, compared to the average values commonly cited. However, for granitic rocks the values obtained are, more or less, comparable to those obtained by Amnuaychai Thienprasert and his colleagues, who worked in the same area using different methods of investigation. Apart from that granitic samples of triassic and cretaceous ages also have a similar radioactive elements concentration to those of the Darby pluton in Southeastern Seward Peninsular, Alaska, the Granite Mountain in Wyoming and the Conway Granite of New Hampshire which has been cited as a low-grade uranium-thorium resource. As a consequence of such high radioactive element concentrations, heat generations of most rock samples investigated are much higher than reported average values. The heat generations seem to have some influence on the nature of heat sources of hot springs in northern Thailand, especially at Ban Pong, Nam Ron hot spring Amphoe Mae Chan. Furthermore the radiogenic heat productions also affect to a great extent surface heat flow in the region provided that the radioactive element concentrations do not decrease with depth. Surface heat flow in northern Thailand was recently reported to be very high compared to the average value of the earth. This high heat flow was suspected to be caused by extensional tectonics resulting indirectly from sea-floor spreading in the Andaman Sea during the last 10 million years. However, from this study it can be shown that heat generations could be another factor which has much influence on the value of the surface heat flow.

    The objective of this case-control study was to identify farm-level risk factors associated with bovine tuberculosis (bTB) in dairy cows in northern Thailand. Spatial analysis was performed to identify geographical clustering of case-farms located in Chiang Mai and Chiang Rai provinces in northern Thailand. To identify management factors affecting bTB status, a matched case-control study was conducted with 20 case-farms and 38 control-farms. Case-farms were dairy farms with at least single intradermal tuberculin test- (SIT-) reactor(s) in the farms during 2011 to 2015. Control-farms were dairy farms with no SIT-reactors in the same period and located within 5 km from case-farms. Questionnaires were administered for data collection with questions based on epidemiological plausibility and characteristics of the local livestock industry. Data were analyzed using multiple logistic regressions. A significant geographic cluster was identified only in Chiang Mai province (p < 0.05). The risk factor associated with presence of SIT-reactors in dairy herds located in this region was purchasing dairy cows from dealers (OR = 5.85, 95% CI = 1.66–20.58, and p = 0.006). From this study, it was concluded that geographic clustering was identified for dairy farms with SIT-reactors in these provinces, and the cattle movements through cattle dealers increased the risks for SIT-reactor farm status.

    In case of species of natural and aromatic plant originated from the northern Thailand, sensory characteristics, especially odours, have unique identifiers of herbs. The instruments sensory analysis have performed by several of differential of sensing, so call `electronic nose', to be a significantly and rapidly for chemometrics. The signal responses of the low cost electronic nose were evaluated by principal component analysis (PCA). The aims of this paper evaluated various of Thai-herbs grown in Northern of Thailand as data preprocessing tools of the Low-cost electronic nose (enNU-PYO1). The essential oil groups of Thai herbs such as Garlic, Lemongrass, Shallot (potato onion), Onion, Zanthoxylum limonella (Dennst.) Alston (Thai name is Makaen), and Kaffir lime leaf were compared volatilized from selected fresh herbs. Principal component analysis of the original sensor responses did clearly distinguish either all samples. In all cases more than 97% for cross-validated group were classified correctly. The results demonstrated that it was possible to develop in a model to construct a low-cost electronic nose to provide measurement of odoriferous herbs.

    Gastrointestinal zoonotic helminths of dogs and cats have a public health concern worldwide. We investigated the prevalence of gastrointestinal helminths of zoonotic significance in dogs and cats in lower Northern Thailand and utilized molecular tools for species identification of hookworms and Opisthorchis viverrini. Fecal samples of 197 dogs and 180 cats were collected. Overall prevalence of infection using microscopy was 40.1% in dogs and 33.9% in cats. Helminth infection found in both dogs and cats included hookworms, Spirometra spp., Taenia spp., Toxocara spp., O. viverrini, Strongyloides spp. and Trichuris spp. Hookworms were the most common helminth in dogs, while Spirometra spp. were the most prevalent in cats. Among hookworm infection in dogs and cats, Ancylostoma ceylanicum was the most prevalent hookworm, being 82.1% in hookworm infected dogs and 95.8% in hookworm infected cats. Mixed-infection due to hookworms and Spirometra spp. was the most dominant in both dogs and cats. Our finding showed that zoonotic helminth infection is highly prevalent in dogs and cats in the lower Northern area of Thailand.

    High levels of polybrominated diphenyl ethers (PBDEs) have been extensively reported in urban areas and at e-waste recycling sites in coastal China. However, data are scarce in northern China and are not available in rural areas at all. In addition, it is often believed that air concentrations in rural areas are lower than those in urban areas without distinguishing rural residential areas and open fields. In this study, air samples were collected at 17 sites covering urban and rural (residential and open field) areas in northern China using active samplers. With BDE-209 dominated in all congeners, the average concentrations of BDE-209 (41 ± 72 pg/m 3 ) and other 13 PBDEs (16 ± 12 pg/m 3 ) were significantly lower than those found in south China, such as in Guangzhou or Hong Kong. On average, the total PBDE concentrations at the urban sites were 2.2 and 2.9 times of those at the rural residential and field sites, respectively. - Graphical abstract: Concentration of PBDEs at each site of the studied area. Highlights: ► High levels of PBDEs with BDE-209 domination were detected in air in northern China. ► PBDE concentrations in rural residential areas were significantly higher than those in rural open fields. ► Proportions of BDE-209 in urban areas were higher than those in rural areas. ► PBDE concentrations were correlated to local population density and Gross Domestic Production. - In northern China, PBDEs in air in rural residential areas were significantly higher than those in open fields.

    We studied traditional medicinal plant knowledge among the Karen in northern Thailand. To compare traditional medicinal knowledge in 14 Karen villages in northern Thailand and determine culturally important medicinal plant species in each Karen village. We interviewed 14 key informants and 438 non-specialist informants about their traditional knowledge of medicinal plants. We tested normality of the data and correlations with distance to the nearest city using Kolmogorov-Smirnov tests and Spearman's rank correlation coefficient. Cluster analysis and cultural importance index (CI) were calculated for the similarity of medicinal plant used and culturally importance medicinal plant species among Karen villages respectively. In total 379 medicinal plant species were used. Number of medicinal plants used positively correlate with distance to the nearest city. Relatively low similarities of medicinal plant species and different CI values for species among the different areas were found. Traditional medicinal plants still play an important role in medicinal practice of the Karen. Local environments, availability of medicinal plant and distance between Karen villages and the nearest city affect the amount of traditional medicinal knowledge in each Karen village. The medicinal plants in this study with high CI values might give some useful leads for further biomedical research. © 2013 Elsevier Ireland Ltd. All rights reserved.

    preliminary study on insects associated with pig carcasses was conducted in Phitsanulok, northern Thailand. Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4- 6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were mainly classified belonging to two orders and nine families, namely order Diptera (family Calliphoridae: Chrysomya rufifacies and Chrysomya megacephala, family Muscidae: Musca domestica, family Faniidae: Fannia canicularis, family Sarcophagidae: Parasarcophaga ruficornis and family Piophilidae: Piophila casei,) and order Coleoptera (family Dermestidae: Dermestes maculatus, family Histeridae: Hister sp., family Cleridae: Necrobia rufipes and family Trogidae: Trox sp). The forensically dominant fly was C. rufifacies, while the beetle was D. maculatus. The beetles associated with pig carcasses found in this study are first reported in Phitsanulok, Thailand. In addition, ants, bees, spiders and millipedes were also associated with the carcasses. These findings may provide data for further use in legal investigations in Thailand.

    Health sciences programs are being designed to attract students who are likely to stay and practice in rural and northern Canada. Consequently, student recruitment and screening are increasingly including assessment of suitability for rural practice. Although retention factors among rural physicians and nurses have been investigated, little is known about factors that contribute to the retention of other healthcare professionals who work in rural areas. The primary objective of this project was to identify the personal characteristics and experiences of allied health professionals who have worked long term in northern British Columbia (BC), Canada. The study used a qualitative descriptive approach. Six speech language pathologists, four psychologists, four occupational therapists, eight social workers, and four physiotherapists practicing long term in northern BC were recruited, using a convenience sample and the snowball technique, to participate in semi-structured telephone interviews. The interviews were audiotaped and transcribed verbatim. A thematic content analysis identified the motivations for their decision to begin or stay working in northern communities, the reasons for choosing rural or northern education and key themes concerning personal characteristics and experiences. A process of member checking and an external audit validated the analysis and findings. There were two major themes for choosing rural and northern education. For some, selection of rural or northern training was based on accessibility to health education programs; all participants who chose rural and northern education had already decided that they were going to practice rurally. Generally, participants identified past positive experiences and rural background as influencing their practice location decision. Participants named the community's need for healthcare professionals, career advancement opportunities, welcoming employers, peer support, as well as promises of continuing

    Full Text Available Three orchid species are newly recorded for the flora of Thailand. The discovery of Macodes petola in the southern part of Peninsular Thailand, adjacent to known occurrences across the Malaysian border, was expected. On the other hand, the find of Cheirostylis octodactyla in Thailand considerably extended the known range of this species to the west, as it was previously known only from the northern part of the Philippines, Taiwan and (through a single collection from northern Vietnam. The recent discovery of populations of Zeuxine bidupensis in Thailand suggests that this species, hitherto considered endemic to Vietnam, does not only have morphological, but also geographic affintities to the little known Z. pantlingii from West Bengal.

    Miang is a fermented food product prepared from the tea leaves of Camellia sinensis var. assamica, and is traditionally produced in mountainous areas of northern Thailand. Although Miang has a long history and reveals deep-rooted cultural involvement with local people in northern Thailand, little is known regarding its microbial diversity. Yeasts were isolated from 47 Miang samples collected from 28 sampling sites, including eight provinces in upper northern Thailand. A hundred and seven yeast isolates were recovered and identified within 14 species based on the comparison of the D1/D2 sequence of the large subunit (LSU) rRNA gene. Candida ethanolica was determined to be the dominant species that was frequently found in Miang together with minor resident yeast species. All yeast isolates demonstrated their tannin-tolerant capability when cultivated on yeast malt agar (YMA) containing 50g/l tannin, but nine isolates displayed clear zones forming around their colonies, e.g., Debaryomyces hansenii, Cyberlindnera rhodanensis, and Sporidiobolus ruineniae. The results obtained from a visual reading method of tannase revealed that all yeast isolates were positive for methyl gallate, indicating that they possess tannase activity. It is assumed that a tannin-tolerant ability is one of the most important factors for developing a yeast community in Miang. This research study is the first report to describe tannin-tolerant yeasts and yeast communities in traditionally fermented tea leaves. Copyright © 2016. Published by Elsevier B.V.

    The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1215 participants, 487 (40.1%) were lowland Thai and 728 (59.9%) were from ethnic minorities. Overall, 17.9% of respondents reported "ever had sex." Lowland Thai adolescents were more likely to have ever had sex compared with ethnic minority adolescents (AOR, 1.61; CI, 1.06-2.45; P< 0.01). A higher proportion of lowland Thai respondents reported having ≥ 2 lifetime sexual partners (51.9% vs. 33.3%, P = 0.003), or currently having a boy/girlfriend (59.9% vs. 45.3%, P< 0.001) compared to ethnic minority adolescents. Consistent condom use was low in both groups (22.6%). The common significant factors associated with "ever had sex" in both groups were "ever drunk alcohol in the past year" and "currently having a boy/girlfriend." Specifically, for lowland Thai youth, being around the age of 17 or 18 years and "ever used methamphetamine in the past year" were associated with increased odds of "ever had sex". For ethnic minority adolescents, being female and belonging to religions other than Buddhism were associated with decreased odds of "ever had sex". A substantially higher proportion of lowland Thai engage in risky sexual behaviors when compared to ethnic minorities. However, both groups remained vulnerable to HIV and other sexually transmitted infections. To minimize sexual risks, education program and school-based interventions are warranted to increase awareness of young people about risky behaviors and to promote essential life skills.

    Based on the current forensic importance of blow flies (Diptera: Calliphoridae), their biological aspects have been studied increasingly worldwide. The blow fly fauna in Phitsanulok Province, Northern Thailand was studied from May 2009 to April 2010 in the residential, agricultural, mountainous and forested areas of Muang, Wat Bot, Nakhon Thai and Wang Thong districts, respectively, in order to know the occurrence of blow flies in this province. Collections were carried out monthly using commercial funnel fly traps and sweeping methods, with 1-day tainted pork viscera as bait. Identification of adult blow flies exhibited 14 634 specimens, comprising of 5 subfamilies, 14 genera and 36 species. Chrysomya megacephala (Fabricius, 1794) and Achoetandrus rufifacies (Macquart, 1843) were the most and second most abundant species trapped, respectively. These two species of carrion flies prevailed in all the types of land investigated. We calculated and compared the diversity indices, species evenness and richness, and similarity coefficients of the blow fly species in various areas. The data from this study may be used to identify the potential of forensicallyimportant fly species within Phitsanulok Province and fulfill the information on blow fly fauna in Thailand.

    Full Text Available Miang is an ethnic fermented tea leaf (Camellia sinensis var. assamica from northern Thailand. It has a long history of sociocultural relationship with northern Thai people. Unlike other types of tea, miang is a unique product that is known as chewing tea or eating tea. In addition, it is also a specific food for traditional religious ceremonies and funerals. Although chewing of miang has become less popular among younger generations, there remains a demand for miang in specific areas of northern Thailand. The traditional fermentation mechanism for miang has not been well documented and the information is now being developed. Current studies indicated that the astringent miang possessed higher phenolic metabolites especially epigallocatechin gallate than the sour miang and fresh tea leaf used for making miang in general. The chemical constituents in miang are of interest and the scientific advances to understand and develop this ethnic tea product are rapidly emerging. Miang has many potential benefits and is proposed to be used for many applications such as foods, pharmaceuticals, and nutraceuticals. Other valuable chemical constituents have not yet been widely reported and require further research. The current understanding of miang has been developed from literature on historic and sociocultural relationships of miang, current evidence scientific evidence, and personal interviews with local miang producers. From the plantation areas close to miang production, physiological, chemical, and microbiological analysis of miang were undertaken and integrated with current scientific literature and community surveys to build an evolving body of new knowledge. This paper provides important historic background of miang and its ethno-botanical relationship with northern Thai people. Traditional production of miang and its chemical and physical properties make miang different from other fermented tea leaves. Therefore, this unique miang with ethnic roots

    Full Text Available Objective: To determine the correlations between the meteorological data and the number of hand foot mouth disease (HFMD cases in 2016 in Northern Thailand, and to estimate the medical costs. Methods: A prospective cohort study was conducted. Data on numbers of HFMD cases were collected from 49 hospitals in three different provinces in Northern Thailand: 16 hospitals from Chiang Rai Province, 7 hospitals from Pha Yao Province, and 26 hospitals from Chiang Mai Province. A questionnaire had been developed and tested for validity and reliability before used. The specific form for collecting meteorological data was developed and used in the field. All information was recorded in the same data spread sheet before analysis. Chi-square and correlation tests were used for explaining the epidemiology of HFMD in the areas. An alpha error at 0.05 was used to determine the statistical significance level. Results: A total of 8 261 cases were analyzed in the study. 56.0% were males, 97.5% aged less than 6 years, 82.6% were out-patient department (OPD cases, 75.5% were reported in raining season, and 43.2% were from Chiang Mai Province. The number of HFMD cases had statistically significant correlations with temperature, air pressure, relative humidity, and rainfall amount. Averagely, 216 baht and 3 678 baht per case per visit had to be expended for medical cost in OPD and IPD cases, respectively. Most of the cases had been reported in the border areas: Thai-Myanmar, and Thai-Lao. Conclusions: Thailand health care system should provide a concrete schedule for taking care of HFMD patients during raining season, and should develop an effective preventive and control program for HFMD particularly among children less than 6 years.

    Cryptosporidium parvum is the most frequent parasitic agent that causes diarrhoea in AIDS patients in Thailand. Cryptosporidiosis outbreaks in humans may be attributed to contamination of their drinking water from infected dairy pastures. A 23-kDa glycoprotein of C. parvum (CpP23) is a sporozoite surface protein that is geographically conserved among C. parvum isolates. This glycoprotein is a potentially useful candidate antigen for the diagnosis of cryptosporidiosis by enzyme-linked immunosorbent assay. Therefore, we investigated the seroprevalence of C. parvum infection in dairy cows in northern Thailand using an ELISA based on recombinant CpP23 antigen. Sera were randomly collected from 642 dairy cows of 42 small-holder farmers, which had the top three highest number of the dairy cows' population in Northern Thailand, that included Chiang Mai, Chiang Rai and Lumpang provinces. The overall seroprevalence of the infection was 4.4%, and the seropositive rates for the three provinces were 3.3% in Chiang Mai, 5.1% in Chiang Rai and 3% in Lumpang. These results suggest that cattle could play a role in zoonotic cryptosporidiosis in Thailand.

    Trace metal elements (TME) can be real threats for living organisms. However, few studies dealt with TME in reservoirs in rural areas where farming practises could induce negative effects. Mae Thang reservoir (northern Thailand) has been studied for 3 years to understand the seasonal behaviour of dissolved TME: Fe, Mn, Cd, Al, Pb, V, Cr, Co, Ni, Cu, Zn, Mo, U and As and associated physicochemical parameters. In situ measurements of these parameters were done during the dry and the wet seasons as well as water samples along the water column for further analyses and TME determination by inductively coupled plasma-mass spectrometry (ICP-MS). In the dry season, the water column was characterized by a strong stratification and anoxic conditions in the hypolimnion. High rain and water input from the watershed during the wet season induced mixing of the water. All TME, except Ni, Co and Cr were less concentrated in the wet season indicating a dilution effect by water input. There was thus no important dissolved pollution coming from the watershed. The anoxic conditions in the dry season enhanced the reduction of Fe and Mn and the desorption processes. Depth, and thus oxic-anoxic conditions were the main drivers of TME in the dry season, while in the wet season, dissolution processes from parent rocks of watershed were favoured. The average concentrations of TME in the reservoir were in the limit of the international and Thai standards. Only localized values in the bottom of the reservoir for Fe and Mn were higher than the limits.

    Full Text Available Poverty alleviation and environmental preservation are very important issues to many governments. Alley farming is beneficial to the environment because it conserves soil and sustains yields over time. Specifically, alley farming reduces soil erosion, which is a major problem in Thailand. Alley farming was conducted on a farmer’s field at Khaokwan Thong, a village in Uthaithani Province, Northern Thailand. We did a two-by-two factorial with and without alley farming, and with and without fertilizer. From this study, we observed that the two species used, Leucaena leucocephala and Acacia auriculiformis, grow well in Thailand, and that alley farming is suitable for Thailand. Few Thai farmers have heard about alley farming. However, it is nevertheless useful to know that there is potential for alley farming in Thailand using the two species. These plants, based upon the diameter and height measurements provided, grew well.

    Atmospheric PM 10 were measured for 12 months at 18 sites along a 2500 km profile across northern China. Annual mean PM 10 concentrations in urban, rural village, and rural field sites were 180 ± 171, 182 ± 154, and 128 ± 89 μg/m 3 , respectively. The similarities in PM 10 concentrations between urban and rural village sites suggest that strong localized emissions and severe contamination in rural residential areas are derived from solid fuels combustion in households. High PM 10 concentrations in Wuwei and Taiyuan were caused by either sandstorms or industrial activities. Relatively low PM 10 concentrations were observed in coastal areas of Dalian and Yantai. Particulate air pollution was much higher in winter and spring than in summer and fall. Multiple regression analysis indicates that 35% of the total variance can be attributed to sandstorms, precipitation and residential energy consumption. Over 40% of the measurements in both urban and rural village areas exceeded the national ambient air quality standard. Highlights: • Spatial distribution of PM 10 concentrations in northern China was investigated. • High levels of PM 10 in rural villages were caused by solid fuel emission. • A strong seasonality with high levels of PM 10 in spring and winter was observed. • Influence of sandstorm, energy consumption, and precipitation were evaluated. • Over 40% of the measurements exceeded the national ambient air quality standard. -- PM 10 concentrations in rural villages of China were comparable with those in the cities, indicating severe air pollution in the rural villages caused by coal and biofuel combustion

Its progress is extremely fast, with extensive necrosis. Delay in treatment, with subsequent huge soft tissue loss and associated severe sepsis, remains a major cause of death in the management of NF. Objective: The aim of this study was to explore clinical characteristics that may be used to predict severe sepsis in patients with NF, in the context of routine clinical practice in northern Thailand. Methods: A retrospective observational cohort study was conducted. The patient cohort in this study consisted of all patients who were diagnosed with NF by surgical or pathological confirmation. The follow-up period started with the admission date and ended with the discharge date. The clinical variables were collected from patients registered at three provincial hospitals in northern Thailand from 2009 to 2012. The clinical predictors for severe sepsis were analyzed using multivariable risk regression. Results: A total of 1,452 patients were diagnosed with NF, either with severe sepsis (n=237 [16.3%] or without severe sepsis (n=1,215 [83.7%].

    Diabetes is a growing epidemic in both urban and rural communities worldwide. We aimed to survey fasting plasma glucose (FPG) status and awareness of diabetes in the rural Karen ethnic community. We investigated the predictors of impaired fasting plasma glucose (IFG) status, which would be easily applicable for prevention of diabetes in a rural community. This was a community-based cross-sectional study conducted at Thasongyang, the most north-western district in Thailand. A total of 299 Karen ethnic rural residents were included in the study. FPG, body mass index, and waist circumference were prospectively measured. We assessed the awareness of diabetes and lifestyle-related health behavior with closed questionnaires in a rural community setting. On screening for FPG, 16.72% of the Karen ethnic residents had hyperglycemia: 3.68% in the diabetic range and 13.04% in the prediabetic range respectively. After adjustment for age, sex, and BMI, waist circumference (adjusted odds ratio [aOR] 3.5, 95% confidence interval [CI] 1.29-9.57), and having a diabetic blood relative (aOR 4.6, CI 1.81-11.71) are significant predictors of IFG status. It is necessary to promote awareness of diabetes among the Karen ethnic community. Application of simple evidence-based predictors of the prediabetic state may lead to timely and effective prevention of diabetes in rural settings.

    To date, few studies have characterized allergens within residences located in rural areas of the northern Rocky Mountain region. In this study, we collected dust samples from 57 homes located throughout western Montana and northern Idaho. Dust samples were collected and later analyzed for dust mite allergens Der f 1 and Der p 1 , Group 2 mite allergens ( Der p 2 and Der f 2 ), domestic feline ( Fel d 1 ), and canine ( Can f 1 ). Indoor temperature and humidity levels were also measured during the sampling program, as were basic characteristics of each home. Dog (96%) and cat (82%) allergens were the most prevalent allergens found in these homes (even when a feline or canine did not reside in the home). Results also revealed the presence of dust mites. Seven percent (7%) of homes tested positive for Der p 1 , 19% of homes were positive for Der f 1 , and 5% of homes were positive for the Group 2 mite allergens. Indoor relative humidity averaged 27.0 ± 7.6% within the homes. Overall, humidity was not significantly associated with dust mite presence, nor was any of the other measured home characteristics. This study provides a descriptive assessment of indoor allergen presence (including dust mites) in rural areas of the northern Rocky Mountains, and provides new information to assist regional patients with reducing allergen exposure using in-home intervention strategies.

    Salmonella enterica serovar Kedougou is among the top 10 serovars reported in northern Thailand. The objective of this study was to identify risk factors associated with Salmonella Kedougou infection in Thailand and to compare the molecular types and antimicrobial resistance with Salmonella Kedougou isolates of human origin from United States and of animal origin from the United Kingdom. Data from 13,976 Salmonella infections of which 253 were Salmonella Kedougou collected in Thailand between 2002 and 2008 were analyzed by logistic regression. Antimicrobial susceptibility testing and pulsed-field gel electrophoresis (PFGE) were performed on selected Salmonella Kedougou strains causing infections in Thailand (n = 66), and compared to isolates from the United States (n = 5) and the United Kingdom (n = 20). Logistic analysis revealed season (hot/dry; p = 0.023), region (northern Thailand; p Thailand were resistant to third-generation cephalosporins: two harbored bla(CTX-M-63) and one bla(CMY-2). PFGE revealed 45 unique clusters. Isolates obtained from humans in Thailand and the United States presented identical PFGE profiles suggesting a travel association, whereas the majority of the animal isolates from United Kingdom clustered separately. This study reveals Salmonella Kedougou as a major cause of human infections in northern Thailand especially during the hot period and suggests a global spread probably due to travel. The clonal types causing infections in humans differed from those observed in animals in United Kingdom, which suggests the absence of an epidemiological link and could suggest differences in virulence. The high frequency of antimicrobial resistance, including emergence of resistance to fluoroquinolones and third-generation cephalosporins, might pose problems for treatment of infections.

    To increase screening and treatment coverage, innovative approaches to cervical-cancer prevention are being investigated in rural Thailand. We assessed the value of a single-visit approach combining visual inspection of the cervix with acetic acid wash (VIA) and cryotherapy. 12 trained nurses provided services in mobile (village health centre-based) and static (hospital-based) teams in four districts of Roi-et Province, Thailand. Over 7 months, 5999 women were tested by VIA. If they tested positive, after counselling about the benefits, potential risks, and probable side-effects they were offered cryotherapy. Data measuring safety, acceptability, feasibility, and effort to implement the programme were gathered. The VIA test-positive rate was 13.3% (798/5999), and 98.5% (609/618) of those eligible accepted immediate treatment. Overall, 756 women received cryotherapy, 629 (83.2%) of whom returned for their first follow-up visit. No major complications were recorded, and 33 (4.4%) of those treated returned for a perceived problem. Only 17 (2.2%) of the treated women needed clinical management other than reassurance about side-effects. Both VIA and cryotherapy were highly acceptable to the patients (over 95% expressed satisfaction with their experience). At their 1-year visit, the squamocolumnar junction was visible to the nurses, and the VIA test-negative rate was 94.3%. A single-visit approach with VIA and cryotherapy seems to be safe, acceptable, and feasible in rural Thailand, and is a potentially efficient method of cervical-cancer prevention in such settings.

    Rice cultivation and energy use for rice production can produce the environmental impacts, especially related to greenhouse gas (GHG) emissions. Also, rice straw open burning by farmers generally practiced after harvesting stage in Thailand for removing the residues in the rice field is associated with emissions of air pollutants, especially particulate matter formation that affects human health and global climate. This study assessed the environmental burdens, consisting of GHG emissions, energy use, and particulate matter formation (PM10), from rice cultivation in Thailand by life cycle assessment (LCA) and compared the environmental burdens of rice straw management scenarios: open burning, incorporation into soil, and direct combustion for electricity generation. The data were collected from the rice production cooperative in Chiang Mai province, northern Thailand, via onsite records and face-to-face questionnaires in 2016. The environmental impacts were evaluated from cradle-to-farm gate. The results showed that the total GHG emissions were 0.64 kg CO 2 -eq per kilogram of paddy rice, the total energy use was 1.80 MJ per kilogram of paddy rice and the PM10 emissions were 0.42 g PM10-eq per kilogram of paddy rice. The results of rice straw management scenarios showed that rice straw open burning had the highest GHG and PM10 emissions. However, rice straw utilization by incorporation into soil and direct combustion for electricity generation could reduce these impacts substantially.

    Full Text Available This article offers a contribution to the anthropology of tourism by investigating the tourism encounter in community-based tourism (CBT in Northern Thailand. It does so by discussing MacCannell’s (1992 idea of the Empty Meeting Grounds and Said’s Orientalism (1978, two works that contributed to research on power inequalities between tourists and residents in the developing world. By establishing a relationship between the two and embedding these in the wider literature on the tourism encounter, this article suggests moving away from binaries towards understanding the space of the tourism encounter and its potential for change. Building on empirical research conducted in Ban Mae Kampong, a CBT village in Northern Thailand, findings suggest that CBT shows signs of resident-host interactions that are based on understanding and learning rather than exploitation. While also in CBT friendships and meaning take time to emerge and the ‘Other’ is used as attraction, villagers’ agency and control over tourism are acknowledged. This paper therefore calls for a revisiting of the theoretical grounding that influences our understanding of the tourism encounter and argues for an investigation of community power relations in connection to the tourism encounter and its potential for residents’ empowerment in CBT.

    The use of decentralised renewable energy technologies to provide rural electrification in developing countries has been a common topic of analysis and policy debate for more than two decades. Unfortunately, a lack of empirical evidence about the field performance of these technologies is a significant barrier to making sound policy decisions about them. Compounded by minimal information sharing between stakeholders, this situation has frequently allowed duplication of inefficient policies. This issue is addressed here by providing empirical evidence gathered from field visits and interviews about the largest government subsidised solar battery charging programme in the world. This analysis highlights the different policies of departments responsible and discusses them with specific attention to their technical, social and economic components. Field study results from over 50 villages in the north of Thailand suggest about 60 per cent of these systems are no longer operational. Many of the technical failures observed are attributed to social factors, as well as flawed implementation strategies

    Full Text Available Hemoglobin E (HbE is one of the most common hemoglobin variants caused by a mutation in the β-globin gene, and found at high frequencies in various Southeast Asian groups. We surveyed HbE prevalence among 8 ethnic groups residing in 5 villages selected for their high period malaria endemicity, and 5 for low endemicity in northern Thailand, in order to uncover factors which may affect genetic persistence of HbE in these groups. We found the overall HbE prevalence 6.7%, with differing frequencies from 0% in the Pwo Karen, the Lawa, and the Skaw Karen to 24% in the Mon. All HbE genes were heterozygous (AE. Differences in HbE prevalence among the studied ethnic groups indirectly documents that ancestries and evolutionary forces, such as drift and admixture, are the important factors in the persistence of HbE distribution in northern Thailand. Furthermore, the presence of HbE in groups of northern Thailand had no effect on the in vitro infectivity and proliferation of Plasmodium falciparum, nor the production of hemozoin, a heme crystal produced by malaria parasites, when compared to normal red-blood-cell controls. Our data may contribute to a better understanding on the persistence of HbE among ethnic groups and its association with malaria.

    Rural and Northern Ontario francophones face many health-related challenges including poor health status, a poor supply of French-speaking physicians, and the potential for an inability or reduced ability to effectively communicate with anglophone healthcare providers. As such, it can reasonably be expected that rural and Northern Ontario francophones experience barriers when receiving care. However, the experience of physicians working in areas densely populated by francophones is largely unexplored. This paper identifies barriers experienced by French-speaking and Non-French-speaking rural and Northern Ontario physicians when serving francophone patients. A series of key informant interviews were conducted with 18 family physicians practicing in rural and urban francophone communities of Northeastern Ontario. Interviews were analyzed using a thematic analysis process. Five categories of barrier were identified: (1) language discordance, (2) characteristics of francophone patients, (3) dominance of English in the medical profession, (4) lack of French-speaking medical personnel, and (5) physicians' linguistic (in)sensitivity. Some barriers identified were unique to Non-French-speaking physicians (eg language discordance, use of interpreters, feelings of inadequacy), some were unique to French-speaking physicians (eg limited French education and resources), and some were common to both groups (eg lack of French-speaking colleagues/staff, added time commitments, and the particularities of Franco-Ontarian preferences and culture). Healthcare providers and decision makers may take interest in these results. Although physicians were the focus of the present article, the barriers expressed are likely experienced by other healthcare providers, and thus the lessons learned from this article extend beyond the physician workforce. Efforts must be made to offer educational opportunities for physicians and other healthcare providers working in areas densely populated by

    Full Text Available Taper refers to the general decrease in the regular outline of a solid body from its base to its tip. Taper models are used to estimate the volume and value of wood products from harvesting trees. Teak (Tectona grandis L.f. is highly valued as one of the world's most preferred timbers and a teak taper equation is required to inform optimal harvesting strategies given the limited plantation resource available in Thailand. Teak taper equations were developed and evaluated based on 331 sample trees collected in 2014 from eight plantations in northern Thailand aged from 10 to 46 yr using two taper model formulations—the Kozak variable-exponent taper model and the Goodwin cubic polynomial model comprising hyperbolic and parabolic terms. Variants based on both model types were fitted using nonlinear regression analysis with diameter at breast height, total tree height and height of girth measurement as the independent variables to estimate diameter underbark at the nominated height. Goodness-of-fit and leave-one-out cross validation with lack-of-fit statistical testing combined with extensive graphical analysis of residuals were used to select the best model. A Goodwin model variant (named FIO-teak1 as the first plantation teak taper model known to be published in Thailand provided the best estimates of volume and diameter underbark. A simple case study confirmed that FIO-teak1 in combination with the Farm Forestry Toolbox software package could assist teak plantation managers in decision making associated with optimizing log grade value based on standing tree inventory data.

    The Mon-Khmer speaking peoples inhabited northern Thailand before the arrival of the Tai speaking people from southern China in the thirteenth century A.D. Historical and anthropological evidence suggests a close relationship between the Mon-Khmer groups and the present day majority northern Thai groups. In this study, mitochondrial and Y-chromosomal DNA polymorphisms in more than 800 volunteers from eight Mon-Khmer and ten Tai speaking populations were investigated to estimate the degree of genetic divergence between these major linguistic groups and their internal structure. A large fraction of genetic variation is observed within populations (about 80% and 90% for mtDNA and the Y-chromosome, respectively). The genetic divergence between populations is much higher in Mon-Khmer than in Tai speaking groups, especially at the paternally inherited markers. The two major linguistic groups are genetically distinct, but only for a marginal fraction (1 to 2%) of the total genetic variation. Genetic distances between populations correlate with their linguistic differences, whereas the geographic distance does not explain the genetic divergence pattern. The Mon-Khmer speaking populations in northern Thailand exhibited the genetic divergence among each other and also when compared to Tai speaking peoples. The different drift effects and the post-marital residence patterns between the two linguistic groups are the explanation for a small but significant fraction of the genetic variation pattern within and between them. © 2011 Kutanan et al; licensee BioMed Central Ltd.

  20. Rainfall model investigation and scenario analyses of the effect of government reforestation policy on seasonal rainfalls: A case study from Northern Thailand

    In this work, 4 models for predicting rainfall amounts are investigated and compared using Northern Thailand's seasonal rainfall data for 1973-2008. Two models, global temperature, forest area and seasonal rainfall (TFR) and modified TFR based on a system of differential equations, give the relationships between global temperature, Northern Thailand's forest cover and seasonal rainfalls in the region. The other two models studied are time series and Autoregressive Moving Average (ARMA) models. All models are validated using the k-fold cross validation method with the resulting errors being 0.971233, 0.740891, 2.376415 and 2.430891 for time series, ARMA, TFR and modified TFR models, respectively. Under Business as Usual (BaU) scenario, seasonal rainfalls in Northern Thailand are projected through the year 2020 using all 4 models. TFR and modified TFR models are also used to further analyze how global temperature rise and government reforestation policy affect seasonal rainfalls in the region. Rainfall projections obtained via the two models are also compared with those from the International Panel on Climate Change (IPCC) under IS92a scenario. Results obtained through a mathematical model for global temperature, forest area and seasonal rainfall show that the higher the forest cover, the less fluctuation there is between rainy-season and summer rainfalls. Moreover, growth in forest cover also correlates with an increase in summer rainfalls. An investigation into the relationship between main crop productions and rainfalls in dry and rainy seasons indicates that if the rainy-season rainfall is high, that year's main-crop rice production will decrease but the second-crop rice, maize, sugarcane and soybean productions will increase in the following year.

    Full Text Available The early life environment appears to have a persistent impact on asthma risk. We hypothesize that environmental factors related to rural life mediate lower asthma prevalence in rural populations, and aimed to investigate an urban-rural gradient, assessed by place of upbringing, for asthma. The population-based Respiratory Health In Northern Europe (RHINE study includes subjects from Denmark, Norway, Sweden, Iceland and Estonia born 1945–1973. The present analysis encompasses questionnaire data on 11,123 RHINE subjects. Six categories of place of upbringing were defined: farm with livestock, farm without livestock, village in rural area, small town, city suburb and inner city. The association of place of upbringing with asthma onset was analysed with Cox regression adjusted for relevant confounders. Subjects growing up on livestock farms had less asthma (8% than subjects growing up in inner cities (11% (hazard ratio 0.72 95% CI 0.57–0.91, and a significant urban-rural gradient was observed across six urbanisation levels (p = 0.02. An urban-rural gradient was only evident among women, smokers and for late-onset asthma. Analyses on wheeze and place of upbringing revealed similar results. In conclusion, this study suggests a protective effect of livestock farm upbringing on asthma development and an urban-rural gradient in a Northern European population.

    The objective was to assess trends in Inuit, First Nations and non-Aboriginal birth outcomes in the rural and northern regions of Quebec. In a birth cohort-based study of all births to residents of rural and northern Quebec from 1991 through 2000 (n = 177,193), we analyzed birth outcomes and infant mortality for births classified by maternal mother tongue (Inuit, First Nations or non-Aboriginal) and by community type (predominantly First Nations, Inuit or non-Aboriginal). From 1991-1995 to 1996-2000, there was a trend of increasing rates of preterm birth for all 6 study groups. In all rural and northern areas, low birth weight rates increased significantly only for the Inuit mother tongue group [RR1.45 (95% CI 1.05-2.01)]. Stillbirth rates showed a non-significant increase for the Inuit mother tongue group [RR1.76 (0.64-4.83)]. Neonatal mortality rates decreased significantly in the predominantly non-Aboriginal communities and in the non-Aboriginal mother tongue group [RR0.78 (0.66-0.92)], and increased non-significantly for the First Nations mother tongue group [RR2.17 (0.71-6.62)]. Perinatal death rates increased for the First Nations mother tongue grouping in northern areas [RR2.19 (0.99-4.85)]. There was a disconcerting rise of some mortality outcomes for births to First Nations and Inuit mother tongue women and to women in predominantly First Nations and Inuit communities, in contrast to some improvements for births to non-Aboriginal mother tongue women and to women in predominantly non-Aboriginal communities in rural or northern Quebec, indicating a need for improving perinatal and neonatal health for Aboriginal populations in rural and northern regions.

    The objective of this study was to assess insecticide resistance in anopheline mosquito populations in agroecosystems with high and low insecticide use in a malaria endemic area in Chiang Mai province in northern Thailand. Anopheline mosquitoes were collected in May and June 2004 from two locations with different agricultural insecticide intensity (HIGH and LOW), but similar in vector control strategies. The F1-generation of Anopheles maculatus s.s. and An. sawadwongporni were subjected to diagnostic doses of methyl parathion (MeP) and cypermethrin (Cyp), both commonly used insecticides in fruit orchards in Thailand. An. minimus A from the HIGH location was subjected to diagnostic doses to Cyp. CDC bottle bioassays were used to determine insecticide susceptibility. Time-mortality data were subjected to Probit analyses to estimate lethal time values (LT50 and LT90). Lethal time ratios (LTR) were computed to determine differences in lethal time response between populations from HIGH and LOW locations. The mortality of An. maculatus to MeP was 74% and 92% in the HIGH and LOW locations, respectively. The corresponding figures for An. sawadwongporni were 94% and 99%. There was no indication of resistance to Cyp for all species tested in either location. The LT90 and LT50 values of An. maculatus s.s. subjected to diagnostic doses of MeP were significantly different between locations (p<0.05). Reduced susceptibility to MeP in mosquito populations in the HIGH location is caused by intensive agricultural pest control and not by vector control activities, because organophosphates have never been used for vector control in the area. Our results indicate that there are still susceptible anopheline populations to pyrethroids, which is consistent with other research from the region. Therefore, there is presently no direct threat to vector control. However increased use of pyrethroids in agriculture may cause problems for future vector control.

    Full Text Available This study focused on the potential parameters, as a result of the upper-air sounding with radiosonde and of the dual polarization radar for detecting hailstorms. The data were collected during the 2012 summer consisting of 12 hail and 1129 no-hail rainstorms of seven studied dates from April to May, 2012. They were analyzed to discern the character of hail and use them as data for detecting hail echoes and for severe weather forecast in upper Thailand. On the day of hail, the instability indices were high enough to contribute to its formation. The following indices include Lifted Index (LI, Showalter Index (SI and Convective Available Potential Energy (CAPE. LI and SI displayed the marginally instability ranged -1 to -4. In the case of CAPE, it could reach the extreme instability (CAPE > 2500 J/kg and also came with the large updraft speed. TITAN software (Thunderstorm Identification, Tracking, Analysis and Nowcasting was also applied for comparing rainstorms with hailstorms. The significant seven echo characteristics included storm period, speed, mean-maximum reflectivity in the horizontal polarization (ZH, area, volume and mass. Based on the character and frequency distributions in summer, hailstorms had greater values of storm duration, area, volume, mass, speed and highest reflectivity than individual rainstorms. Besides, the mean reflectivity of the storms was a negligible factor to identify the type of storm.For the case study on hail by determining polarimetric radar measurement at S-band across Chiang Maun, Northern Thailand, radar signatures with EDGE software showed that the hail was detected 100% during its falling. It also presented as followings: Vertically integrated liquid (VIL exceeding 100 kg/m2, ZH over 60dBZ near the surface and ETOP greater than 17 km. Differential reflectivity (ZDR of rain-hail mixtures almost reached zero. In addition, the coincidental values of correlation coefficient (CC were ranged 0.988 and 0.996, and

    Problems of water supply in many rural regions of Thailand result from the lack of awareness and financial limitations. Payanghang Clean Water Plant is an example of the rural water plant that has been suffering from the poor operation since 2003. The objective of this study was to modify the operation processes of this water plant to achieve cleaner water and better financial condition. Low-cost engineering techniques, such as the use of floating switches in filtration ponds, the use of water drip system for alum dosing and the addition of Tamarindus indica Linn seed solution was applied. As a result, 76% of turbidity removal efficiency was derived. Although, the difference was not statistically significant at 95% confidence level, higher removal efficiency in comparison with the one before modification (65%) suggested better operation. In the view of financial aspect, l07 dollars (1 baht = 0.0326 U.S. dollar) benefit was obtained from 7 month-operation period. (author)

    Longan is one of the most widely cropped fruits in Northern Thailand, where a significant amount of the annual harvest is commercially dried and exported as a commodity. Liquefied petroleum gas is generally used as the energy source for heating the drying air, but concern is growing as fuel prices are expected to increase for the foreseeable future. Meanwhile, with the ample solar radiation in Thailand, the roofs of drying facilities could be adapted to serve as solar collectors to preheat the drying air, thus reducing the energy requirement from fossil fuels. In this study, a simulation program for a flat-plate solar air heater was used to estimate the potential to preheat drying air given the conditions of several longan drying facilities. Results showed that solar collectors can replace up to 19.6% of the thermal energy demand during the drying season. Bigger collectors and smaller air channels result in more useful heat, but attention has to be paid to costs and pressure drop, respectively. Annual monetary savings can reach up to THB 56,000 ({approx}US$ 1800 at US$ 1 THB 31). (author)

    This study uses the influence of presumed media influence model as the theoretical framework to examine how perceived social norms (i.e., descriptive, subjective, and injunctive norms) will mediate the influence of pro- and antidrinking media messages on adolescents' intention to consume alcohol in rural Thailand. Data collected from 1,028 high school students indicate that different mechanisms underlie drinking intentions between nondrinkers and those who have consumed alcohol or currently drink. Among nondrinkers, perceived peer attention to prodrinking messages indirectly influenced adolescents' prodrinking attitudes and intentions to consume alcohol through all three types of perceived social norms. Among drinkers, perceived peer attention to pro- and antidrinking messages indirectly influenced adolescents' prodrinking attitudes and intentions to drink alcohol through perceived subjective norm. The findings provide support for the extended influence of presumed media influence model and have practical implications for how antidrinking campaigns targeted at teenagers in Thailand might be designed.

    In Thailand, Buddhist monks and temples are scattered throughout the country even in the rural poor. There are approximately one temple and four monks for every two villages of about 1000 people. If Buddhist monks are able to expand their roles to health care and education, Buddhist temples will automatically become community health posts and 'Health for All by The Year 2000' will be achieved within 5-10 years in Thailand. Therefore, a volunteer monk-training program has been carried out and about 2000 graduates have returned to their community to disseminate primary health care. However, a systematic and 'industrialized' approach is necessary to get some visible impact on the health of the rural Thai population.

  14. USING A DEA MANAGEMENT TOOLTHROUGH A NONPARAMETRIC APPROACH: AN EXAMINATION OF URBAN-RURAL EFFECTS ON THAI SCHOOL EFFICIENCY

    2009-04-01

    Full Text Available This paper examines urban-rural effects on public upper-secondary school efficiency in northern Thailand. In the study, efficiency was measured by a nonparametric technique, data envelopment analysis (DEA. Urban-rural effects were examined through a Mann-Whitney nonparametric statistical test. Results indicate that urban schools appear to have access to and practice different production technologies than rural schools, and rural institutions appear to operate less efficiently than their urban counterparts. In addition, a sensitivity analysis, conducted to ascertain the robustness of the analytical framework, revealed the stability of urban-rural effects on school efficiency. Policy to improve school eff iciency should thus take varying geographical area differences into account, viewing rural and urban schools as different from one another. Moreover, policymakers might consider shifting existing resources from urban schools to rural schools, provided that the increase in overall rural efficiency would be greater than the decrease, if any, in the city. Future research directions are discussed.

    Dengue fever is a mosquito-borne disease accounting for 50-100 million annual cases globally. Laos and Thailand are countries in south-east Asia where the disease is endemic in both urban and rural areas. Household water storage containers, which are favourable breeding sites for dengue mosquitoes, are common in these areas, due to intermittent or limited access to water supply. This study assessed the effect of household water management and socio-demographic risk factors on Aedes aegypti infestation of water storage containers. A cross-sectional survey of 239 households in Laos (124 suburban and 115 rural), and 248 households in Thailand (127 suburban and 121 rural) was conducted. Entomological surveys alongside semi-structured interviews and observations were conducted to obtain information on Ae. aegypti infestation, socio-demographic factors and water management. Zero-inflated negative binomial regression models were used to assess risk factors associated with Ae. aegypti pupal infestation. Household water management rather than socio-demographic factors were more likely to be associated with the infestation of water containers with Ae. aegypti pupae. Factors that was significantly associated with Ae. aegypti infestation were tanks, less frequent cleaning of containers, containers without lids, and containers located outdoors or in toilets/bathrooms. Associations between Ae. aegypti pupae infestation, household water management, and socio-demographic factors were found, with risk factors for Ae. aegypti infestation being specific to each study setting. Most of the containers did not have lids, larvicides, such as temephos was seldom used, and containers were not cleaned regularly; factors are facilitating dengue vector proliferation. It is recommended that, in Lao villages, health messages should promote proper use and maintenance of tightly fitted lids, and temephos in tanks, which were the most infested containers. Recommendations for Thailand are that small

    Full Text Available Rice, the seed of Oryza species, is the major cereal crop in most of the developing countries. Nearly 95% of global rice production is done in Asian countries, and about half of the world’s population consumes it. Some speciality rices are not commonly consumed. Colored rice is one of such variety. In these varieties, high amounts of anthocyanin pigment are deposited in the rice coat to form its black (also known as purple, brown and red colors. Minimum studies are there to explain the properties of these rice varieties of Thailand. Thus, the current study was aimed to assess the physicochemical and antioxidative properties of three rice varieties (Chiang Mai Black rice, Mali Red rice and Suphanburi-1 Brown rice of different cultivars of northern Thailand. Rice bran extracts of these three cultivars were prepared with different solvents (polar and non-polar for the evaluation of total phytochemical content and anti-oxidant free-radical-scavenging properties. Chiang Mai Black rice contained higher concentration of phenolic acid, flavonoids, and anthocyanins (Cyanidin 3-glucoside, peonidin 3-glucoside, cyanidin chloride.

    This paper aims at exploring the local background of and solutions to the forest conflict in upland areas inhabited by ethnic minorities, who are called hill tribes, in northern Thailand. A so-called hill tribe problem has been officially identified as a result of the slash-and-burn cultivation and other perceived problems, such as opium poppy cultivation, illegal immigration, and the suspicion of disloyalty to the state. This has created distrust and tension between the groups and authorities. The local conflict has recently been related to the dilemma of conserving the forest from all human interference, while many people live and make their livelihood within and adjacent to the protected areas. Furthermore, as the results imply, strictly protected areas and reforestation have also increased the competition over land and natural resources and, thereby, the likelihood of local conflicts. The scarcity and pollution of water, illegal logging, and poor fire control have contributed to the conflicts between local communities. The conflicts between the local communities and officials have been nourished by political and public discussions. Using definitions and terms with negative connotations and ignoring the heterogeneity between the groups or labeling some groups as malevolent have increased distrust and strengthened existing stereotypical images. Conflict resolution starts with efforts toward better mutual understanding, and changes in structures and attitudes are necessary. Local cooperation, utilization of traditional methods, and local institutions are central to conflict solving.

    The tropical storm, floodwater, and the floodplain-sediment layer of a 100-year recurrence flood are examined to better understand characteristics of large monsoon floods on medium-sized rivers in northern Thailand. Storms producing large floods in northern Thailand occur early or late in the summer rainy season (May October). These storms are associated with tropical depressions evolving from typhoons in the South China Sea that travel westward across the Indochina Peninsula. In late September, 2005, the tropical depression from Typhoon Damrey swept across northern Thailand delivering 100 200 mm/day at stations in mountainous areas. Peak flow from the 6355-km2 drainage area of the Ping River upstream of the city of Chiang Mai was 867 m3s-1 (river-gage of height 4.93 m) and flow greater than 600 m3s-1 lasted for 2.5 days. Parts of the city of Chiang Mai and some parts of the floodplain in the intermontane Chiang Mai basin were flooded up to 1-km distant from the main channel. Suspended-sediment concentrations in the floodwater were measured and estimated to be 1000 1300 mg l-1. The mass of dry sediment (32.4 kg m-2), measured over a 0.32-km2 area of the floodplain is relatively high compared to reports from European and North American river floods. Average wet sediment thickness over the area was 3.3 cm. Sediment thicker than 8 cm covered 16 per cent of the area, and sediment thicker than 4 cm covered 44 per cent of the area. High suspended-sediment concentration in the floodwater, flow to the floodplain through a gap in the levee afforded by the mouth of a tributary stream as well as flow over levees, and floodwater depths of 1.2 m explain the relatively large amount of sediment in the measured area. Grain-size analyses and examination of the flood layer showed about 15-cm thickness of massive fine-sandy silt on the levee within 15-m of the main channel, sediment thicker than 6 cm within 200 m of the main channel containing a basal coarse silt, and massive clayey

    Full Text Available Migration is one of the top debate topics in terms of the national policy agendas of middle-income countries, and Thailand is no exception. The segmentation of its labour market explains why Thailand is experiencing large-scale immigration and a simultaneous emigration of low-skilled workers. Immigration inflows from its less-developed neighbour countries – namely, Laos, Cambodia and Myanmar – pose a challenge for Thailand. Wage differentials between Thailand and other migrant-receiving countries, which are mostly more economically developed than Thailand, also stimu-late emigration from there. Due to regional disparities within the country and to a lack of employment and educational opportunities in rural areas, internal migration is also common and encouraged. In this paper I first analyse the economic pros and cons of migration both to and within Thailand before formulating labour migration policies that aim to maximize beneficial outcomes while minimizing economic costs. The cost–benefit analysis of labour migration is key to addressing relevant gaps in formulating and implementing effective policies.

  3. The Thai Business Initiative in Rural Development (TBIRD): a new dimension in rural development.

    The Population and Community Development Association (PDA) promotes family planning (FP) throughout Thailand through a community-based approach. The Thai government actively supports rural development. In 1986, 80% of Thailand's people who lived below the poverty line were in rural areas. The poverty line in rural areas is an annual per capita income of 3823 baht, or US $153; in urban areas, it is more. Since 1984, Thailand's gross domestic product (GDP) has increased by more than 50%. Per capita GDP has risen dramatically, also, with the success of FP efforts. This economic achievement, however, has not been shared by most of the Thai population. Incomes in the agriculture sector are far below those in the nonagricultural sector. The government and the nonprofit organizations, however, do not have skills. The corporate sector does have these skills. The Thailand Business Initiative in Rural Development (TBIRD) helps companies sponsor villages and aids them in developing business skills, whereupon income levels and local living standards are improved. Companies thus help in the employment transfer from agriculture to nonagriculture. There is a "one-company-one- village" formula. Company employees have the skills needed in the villages. They are directly involved. Since 1988, PDA has been working with companies in Thailand to help villages develop business skills. In Saraburi province, PDA and Volvo Swedish Motors have been aiding villagers to grow saplings and sell them to golf course and housing developers. In Ayutthaya Province, PDA and the same company are helping the residents with needlepoint and embroidery to supply a wedding dress manufacturing operation. These programs have succeeded. PDA wants to expand the program by September 1990, to include 50 companies. It is hoped that once the companies are comfortable with their relationship to the village, they will start associations with additional villages. PDA has established the "Ten Steps to Adopt a Village."

    Key differences between urban and rural populations can influence the adoption and impacts of new cooking technologies and fuels. We examine these differences among urban and rural households that are part of the REACCTING study in Northern Ghana. While urban and rural populations in the study area all use multiple stoves, the types of stoves and fuels differ, with urban participants more likely to use charcoal and LPG while rural households rely primarily on wood. Further, rural and urban households tend to use different stoves/fuels to cook the same dishes—for example, the staple porridge Tuo Zaafi (TZ) is primarily cooked over wood fires in rural areas and charcoal stoves in urban settings. This suggests that fuel availability and ability to purchase fuel may be a stronger predictor of fuel choice than cultural preferences alone. Ambient concentrations of air pollutants also differ in these two types of areas, with urban areas having pollutant hot spots to which residents can be exposed and rural areas having more homogeneous and lower pollutant concentrations. Further, exposures to carbon monoxide and particulate matter differ in magnitude and in timing between urban and rural study participants, suggesting different behaviors and sources of exposures. The results from this analysis highlight important disparities between urban and rural populations of a single region and imply that such a characterization is needed to successfully implement and assess the impacts of household energy interventions.

  5. Agrosilvopastoral Systems in Northern Thailand and Northern Laos: Minority Peoples’ Knowledge versus Government Policy

    2014-05-01

    Full Text Available Traditional agrosilvopastoral systems have been an important component of the farming systems and livelihoods of thousands of ethnic minority people in the uplands of Mainland Southeast Asia. Drawing on a combination of qualitative and participatory inquiries in nine ethnic minority communities, this study emphasizes the complex articulation of local farmers’ knowledge which has been so far excluded from governmental development and conservation policies in the northern uplands of Thailand and Laos. Qualitative analysis of local knowledge systems is performed using the Agroecological Knowledge Toolkit (AKT5 software. Results show that ethnic minorities in the two countries perceive large ruminants to be a highly positive component of local forest agro-ecosystems due to their contribution to nutrient cycling, forest fire control, water retention, and leaf-litter dispersal. The knowledge and perceptions of agrosilvopastoral farmers are then contrasted with the remarkably different forestry policy frameworks of the two countries. We find that the knowledge and diversity of practices exercised by ethnic minority groups contrasts with the current simplified and negative image that government officials tend to construct of agrosilvopastoral systems. We conclude that local knowledge of forest-livestock systems can offer alternative or complementary explanations on ecological cause-and-effect relationships which may need further scientific investigation and validation.

    A new species, Bruchidius paicus (Insecta, Coleoptera) reared from the seeds of a leguminous tree, Albizia lebbeck (Fabaceae: Mimosoideae: Ingeae), is described from Northern Thailand. Inspection of genital and external morphological traits of B. paicus revealed that the new species belongs to Bruchidius Group 5 (sensu ). The definition of Group 5 is reviewed based on both external and genital morphology. Further comparison of the group to molecular Clade I of Bruchidius (sensu ) indicates the two groups correspond to each other.

    After more than a decade of the AIDS epidemic in Thailand, the number of children whose parents are living with HIV or have died from AIDS is increasing significantly and it has been reported that these children are often discriminated against by their peers. In order to better understand the current situation and to explore possible strategies to support HIV-affected children, this study examined children's attitudes towards HIV and AIDS using questionnaires and focus group discussions with children in Grades three-six in five primary schools in a northern province in Thailand. A total of 513 children (274 boys and 239 girls) answered the questionnaire and five focus groups were organised. The findings showed a strong positive correlation between children's belief that HIV could be transmitted through casual contact and their negative attitudes towards their HIV-affected peers. Most children overestimated the risk of HIV transmission through casual contact and this made their attitudes less tolerant and less supportive. After HIV prevention education (which included information on HIV transmission routes) was given in three of the study schools, the same questionnaire and focus groups were repeated and the findings showed that children's attitudes had become more supportive. These findings suggest that HIV prevention education delivered through primary schools in Thailand can be an effective way to help foster a more supportive and inclusive environment and reduce the stigma and discrimination that decrease educational access and attainment for HIV-affected schoolchildren.

    This paper studies a pilot project in which photovoltaic systems were installed in thirty-six places in the remote areas of Thailand with no access to electricity. One sub-project out of thirty-six was chosen for in-depth investigation. We discuss the appropriateness of solar energy for Thailand context. The diffusion process of PV systems is analyzed on four elements: innovation, communication channel, time and social system. This project is an extreme case as the PV systems and services were provided for free of charge. Even so, there are still some challenges to get acceptance for this sustainable form of energy.

    This study was conducted to determine the prevalence of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) in pigs, farm workers, and the environment in northern Thailand, and to assess LA-MRSA isolate phenotypic characteristics. One hundred and four pig farms were randomly selected from the 21,152 in Chiang Mai and Lamphun provinces in 2012. Nasal and skin swab samples were collected from pigs and farm workers. Environmental swabs (pig stable floor, faucet, and feeder) were also collected. MRSA was identified by conventional bacterial culture technique, with results confirmed by multiplex PCR and multi locus sequence typing (MLST). Herd prevalence of MRSA was 9.61% (10 of 104 farms). Among pigs, workers, and farm environments, prevalence was 0.68% (two of 292 samples), 2.53% (seven of 276 samples), and 1.28% (four of 312 samples), respectively. Thirteen MRSA isolates (seven from workers, four from environmental samples, and two from pigs) were identified as Staphylococcal chromosomal cassette mec IV sequences type 9. Antimicrobial sensitivity tests found 100% of the MRSA isolates resistant to clindamycin, oxytetracycline, and tetracycline, while 100% were susceptible to cloxacillin and vancomycin. All possessed a multidrug-resistant phenotype. This is the first evidence of an LA-MRSA interrelationship among pigs, workers, and the farm environment in Thailand.

    Full Text Available Managing forests for their satisfactory provision of multiple goods and services to both the global and local commons requires effective cross-scale cooperation between local management institutions and state management institutions. Integrating the distinct sets of knowledge produced and used at the two scales of management has proven very challenging. This paper shows how a better understanding of the spatial expression of knowledge operating at distinct scales can help lead to a more fruitful integration of local knowledge and practice with state knowledge and practice. Using a case study from northern Thailand, this paper examines the links between the production of knowledge and the production of space within resource management institutions. It then identifies moments of convergence, compatibility, and conflict between local and state management institutions to inform more effective cross-scale linkages in environmental management.

    Many ecosystem services provided by forests are important for the livelihoods of indigenous people. Sacred forests are used for traditional practices by the ethnic minorities in northern Thailand and they protect these forests that are important for their culture and daily life. Swidden fallow fields are a dominant feature of the agricultural farming landscapes in the region. In this study we evaluate and compare the importance of swidden fallow fields and sacred forests as providers of medicinal plants among the Karen and Lawa ethnic minorities in northern Thailand. We made plant inventories in swidden fallow fields of three different ages (1-2, 3-4, 5-6 years old) and in sacred forests around two villages using a replicated stratified design of vegetation plots. Subsequently we interviewed the villagers, using semi-structured questionnaires, to assess the medicinal use of the species encountered in the vegetation survey. We registered a total of 365 species in 244 genera and 82 families. Of these 72(19%) species in 60(24%) genera and 32(39%) families had medicinal uses. Although the sacred forest overall housed more species than the swidden fallow fields, about equal numbers of medicinal plants were derived from the forest and the fallows. This in turn means that a higher proportion (48% and 34%) of the species in the relatively species poor fallows were used for medicinal purposes than the proportion of medicinal plants from the sacred forest which accounted for 17-22%. Of the 32 medicinal plant families Euphorbiaceae and Lauraceae had most used species in the Karen and Lawa villages respectively. Sacred forest are important for providing medicinal plant species to the Karen and Lawa communities in northern Thailand, but the swidden fallows around the villages are equally important in terms of absolute numbers of medicinal plant species, and more important if counted as proportion of the total number of species in a habitat. This points to the importance of

    China contributes 23 % of global carbon emissions, of which 26 % originate from the household sector. Due to vast variations in both climatic conditions and the affordability and accessibility of fuels, household carbon emissions (HCEs) differ significantly across China. This study compares HCEs (per person) from urban and rural regions in northern China with their counterparts in southern China. Annual macroeconomic data for the study period 2005 to 2012 were obtained from Chinese government sources, whereas the direct HCEs for different types of fossil fuels were obtained using the IPCC reference approach, and indirect HCEs were calculated by input-output analysis. Results suggest that HCEs from urban areas are higher than those from rural areas. Regardless of the regions, there is a similarity in per person HCEs in urban areas, but the rural areas of northern China had significantly higher HCEs than those from southern China. The reasons for the similarity between urban areas and differences between rural areas and the percentage share of direct and indirect HCEs from different sources are discussed. Similarly, the reasons and solutions to why decarbonising policies are working in urban areas but not in rural areas are discussed.

    Full Text Available Northern Thailand has a high burden HIV epidemic among MSM and TG. Oral pre-exposure prophylaxis (PrEP with tenofovir-emtricitabine has demonstrated efficacy in preventing HIV among MSM and TG in Chiang Mai, Thailand. Determinants of PrEP acceptability are needed to gauge the potential uptake of this prevention strategy.From January to February 2012, 238 MSM and TG participants, who self-reported as HIV-uninfected or of unknown status, completed a self-administered survey on hand-held computers. Participants were recruited by venue-day-time sampling and asked to rate their likelihood of using oral PrEP for HIV prevention with an efficacy of 50%. PrEP acceptability was defined as being "very likely" to use PrEP. Odds ratios and 95% CIs were calculated to identify correlates of acceptability.131 MSM and 107 TG responded, with mean ages of 23.7 and 21.8, respectively. 24% of MSM engaged primarily in receptive anal sex vs. 74% of TG. 21% of MSM and 44% of TG reported regular medication use. Prior awareness of PrEP was high at 66% among both MSM and TG respondents. 41% of MSM and 37% of TG were "very likely" to use PrEP. Among MSM, factors associated with PrEP acceptability included a prior history of STIs (AOR 4.6; 95%CIs 1.7-12.6, previous HIV testing (AOR 2.4 95%CIs 1.1-5.3, regularly planned sex (AOR 2.8 95%CIs 1.1-7.2, and infrequent sex (AOR 2.9 95%CIs 1.3-6.3. Among TG, factors associated with acceptability included prior awareness of PrEP (AOR 3.3; 95%CIs 1.2-9.0 and having private insurance (AOR 5.0; 95%CIs 1.3-19.0.MSM and TG in Northern Thailand are distinct groups in terms of sexual behaviors, patterns of medication use, and correlates of PrEP acceptability. Efforts to maximize PrEP uptake should include expanded HIV testing services and the provision of financial subsidies to reduce the cost of PrEP.

    Osteosarcoma is a common and aggressive primary malignant bone tumor occurring in children and adolescents. It is one of the most aggressive human cancers and the most common cause of cancer-associated limb loss. As treatment in Thailand has produced a lower survival rate than in developed countries; therefore, this study identified survival rate and the poor prognostic factors of osteosarcoma in Northern Thailand. The retrospective cases of osteosarcoma, diagnosis between 1 January 1996 and 31 December 2013, were evaluated. Five and ten year overall survival rates were analyzed using time-to-event analysis. Potential prognostic factors were identified by multivariate regression analysis. There were 208 newly diagnosed osteosarcomas during that period, and 144 cases met the criteria for analysis. The majority of the osteosarcoma cases (78.5%) were aged 0-24 years. The overall 5- and 10-year survival rates were 37.9% and 33.6%, respectively. Presence of metastasis at initial examination, delayed and against treatment co-operation, and axial skeletal location were identified as independent prognostic factors for survival, with hazard ratios of 4.3, 2.5 and 3.8, and 3.1, respectively. This osteosarcoma cohort had a relatively poor overall survival rate. The prognostic factors identified would play a critical role in modifying survival rates of osteosarcoma patients; as rapid disease recognition, a better treatment counselling, as well as improving of chemotherapeutic regimens were found to be important in improving the overall survival rate in Thailand.

    2010-07-01

    Full Text Available Only few well-dated records document the evolution of Southeast Asian paleoenvironments during the Cenozoic. Here we analyse continental pollen assemblages from Late Oligocene and Miocene fossil sites of Thailand. In agreement with previous studies, palynoflora from the Oligocene suggests warm temperate forested habitats at 24–26 Ma, whereas Middle Miocene assemblages are made of thermophilous taxa. This change can be linked to the major climate reorganization that brought warmer and wetter conditions over Southeast Asia around 22 Ma. This study also provides the first submillional records from the Middle Miocene of Thailand. Thirteen samples of lignite layers from the sivaladapid-bearing Mae Moh site, dated between 13.3 and 13.1 Ma, and six samples from the hominoid-bearing Chiang Muan deposit, dated between 12.4 and 12.2 Ma, document oscillations between tropical woodlands and grasslands in northern Thailand. These pollen records likely reflect climate variations linked to insolation variations. Late Miocene palynological assemblages from Khorat, northeastern Thailand, document fluviolacustrine paleoenvironments alternatively covered by thermophilous trees and grasslands. These records show that both sivaladapids and early hominoids from Thailand have evolved in tropical environments with high variability in the vegetation cover.

    Full Text Available This study aimed to investigate the physicochemical properties and chemical composition of epicuticular wax extracted from leaves of Kluai Namwa, a banana cultivar which is widely grown in Northern Thailand. Its genotype was identified by a botanist. The wax was extracted using solvent extraction. The fatty acid profiles and physicochemical properties of the wax namely melting point, congealing point, crystal structures and polymorphism, hardness, color, and solubility were examined and compared to those of beeswax, carnauba wax and paraffin wax. The results showed that the genotype of Kluai Namwa was Musa acuminata X M. balbisiana (ABB group cv. Pisang Awak. The highest amount of wax extracted was 274 μg/cm2 surface area. The fatty acid composition and the physicochemical properties of the wax were similar to those of carnauba wax. It could be suggested that the banana wax could be used as a replacement for carnauba wax in various utilizing areas.

    We describe a new forest-dwelling Cyrtodactylus from Doi Inthanon, Chiang Mai Province, northern Thailand. Cyrtodactylus inthanon sp. nov. is characterized by a maximum known SVL of 87.3 mm; 18 to 20 longitudinal rows of dorsal tubercles; a continuous series of 34 to 37 enlarged femoro-precloacal scales, including four to six pitted (female) or pore-bearing (male) scales on each femur separated by a diastema from five pitted (females) or pore-bearing (male) precloacal scales; no precloacal groove or depression; transversely enlarged subcaudal scales; and three to five irregular beige dorsal bands between limb insertions. The discovery of a new reptile endemic to Doi Inthanon reinforces the high importance of this mountain in terms of biodiversity conservation.

  4. Thailand's reproductive revolution.

    Thailand has achieved a remarkable population revolution in the past 15 years, resulting in a fertility decline of 44%, the 3rd greatest decline of the major developing countries. Thailand is quite distinct from either China or South Korea, the leaders in fertility decline. It has neither China's authoritarian power system to enforce population control nor the highly developed, Westernized outlook of South Korea. Instead it achieved its astounding fertility drop through a noncoercive family planning program operating within a context of rapid social change and a cultural setting. Thailand's drop in population growth has touched almost all segments of Thai society. The preferred number of children among couples married less than 5 years has dropped in both rural and urban families at almost exactly the same rate, from about 3.2 in 1969 to 2.3 in 1984. Religious groups represent the only substantial difference in family size preference; Moslem women married less than 5 years stated a desired average of 3.1 children versus 2.3 for Buddhist women. The direct case of the fertility drop is a national increase in contraceptive use. In 1984, 65% of Thai women reported using contraception. The Thai population, however, was ripe for using contraception when it became available due to 1) mass media creating a desire for consumer goods, 2) the increased costs of education to parents, 3) the willingness of parents to trade off "parent repayment" from many children for a few quality children, 4) couples' autonomy in fertility decision making, 5) the high status of women in Thailand, and 6) the fact that Buddhism poses no barriers to contraception. Current trends show no immediate sign of change.

    Full Text Available A greater flow of people to and from each of the Mekong countries is catching the attention of the general public and academic researchers. As one of the fastest growing countries in the GMS, Thailand is attracting the majority of migrant workers from its neighbours. At a smaller scale, when compared with those from Lao PDR, Cambodia and Myanmar, Vietnamese workers are also joining this increasing trend in immigration to Thailand. By analyzing information from secondary data sources, this research paper attempts to provide further insights into the social and economic impacts generated by the Vietnamese migrant workers in Thailand both at home and the host country. The study discovers that moving to Thailand for work has eased the pressures of rural unemployment and underemployment that have plagued Vietnam recently. Meanwhile, Vietnamese workers are helping soothe the stress caused by the increasing demand for unskilled and low skilled labourers in Thailand. The study further learns that the long-established community of Vietnamese migrants in Thailand is encouraging the increasing movement of Vietnamese workers to Thailand. The study findings suggest meaningful implications for future policies in leveraging labour migration for development.

    The double burden of communicable and noncommunicable diseases (NCD) is an increasing trend in low- and-middle income developing countries. Rural and minority populations are underserved and likely to be affected severely by these burdens. Knowledge among young people could provide immunity to such diseases within a community in the long term. In this study we aimed to assess the knowledge of several highly prevalent NCDs (diabetes, hypertension, and chronic obstructive pulmonary disease [COPD]) and several highly incident communicable diseases (malaria and diarrheal diseases) among Karen high school students in a rural district in far northwest of Thailand. The aim of the study is to explore information for devising life-course health education that will be strategically based in schools. A cross-sectional survey approved by the ethics committee of Boromarajonani College of Nursing Nakhon Lampang (BCNLP), Lampang, Thailand was conducted in Thasongyang, Tak province, from September 2011 to January 2012. Questionnaires for assessing knowledge regarding diabetes, hypertension, COPD, malaria, and diarrheal diseases were delivered to all 457 Karen high school students attending Thasongyang high school. A total of 371 students returned the questionnaires. Experts' validation and split-half reliability assessment was applied to the instrument. Students' main sources of health information were their teachers (62%), health care workers (60%), television (59%), and parents (54%). Familial risk factors of diabetes and hypertension were not known to more than two thirds of the students. Except obesity and physical inactivity, lifestyle-related risk factors were also not known to the students. Though living in a malaria-endemic area, many of the Karen students had poor knowledge about preventive behaviors. Half of the students could not give a correct answer about the malaria and hygienic practice, which might normally be traditionally relayed messages. Health education and

    Soil-gas radon concentration anomaly map was constructed to help detect an unknown subsurface fault location in San Sai District, Chiang Mai Province, Northern Thailand where a 5.1-magnitude earthquake took place in December 2006. It was suspected that this earthquake may have been associated with an unrecognized active fault in the area. In this study, soil-gas samples were collected from eighty-four measuring stations covering an area of approximately 50 km2. Radon in soil-gas samples was quantified using Scintrex Radon Detector, RDA-200. The samplings were conducted twice: during December 2014-January 2015 and March 2015-April 2015. The soil-gas radon map obtained from this study reveals linear NNW-SSE trend of high concentration. This anomaly corresponds to the direction of the prospective fault system interpreted from satellite images. The findings from this study support the existence of this unknown fault system. However a more detailed investigation should be conducted in order to confirm its geometry, orientation and lateral extent.

  9. Influence of Favorite Place in House—Outdoor or Indoor—On Energy Consumption and Happiness in Rural Thailand

    Full Text Available In recent years, with the change in house styles in rural Thailand, the favorite place in the house and lifestyle of inhabitants has also altered. This causes an increase in energy use. Therefore, this research was conducted in order to clarify the influence on energy use of the house style, communication with the neighborhood, and happiness through the favorite place in the house and daily activities. The study identified that people who like to stay in the outside space, such as the open space beneath the house and the garden, showed higher happiness. Spending more time outside helped to communicate with the neighborhood and family, and also to use less the air conditioner and electric fan. Such a lifestyle contributes to the development of a low carbon society.

    Full Text Available Organic solvent and hot water extracts of freshwater macroalgae, Cladophora glomerata and Microspora floccosa, harvested from Nan River in northern Thailand were screened for antioxidant and anticancer activities using DPPH free radical scavenging assay and inhibition of proliferation of the KB human oral cancer cell lines respectively. The ethyl acetate extract of C. glomerata showed the highest total phenol content (18.1±2.3 mg GAE/g, radical scavenging activity (49.8±2.7% DPPH scavenging at 100 g/ml and in vitro growth inhibition (IC50=1420.0±66 g/g of the KB cell lines. These results indicate that C. glomerata could be a source of valuable bioactive materials.

  11. Agricultural Commercialisation, Diversification, and Conservation of Renewable Resources in Northern Thailand Highlands

    2013-02-01

    Full Text Available The process of commercialisation-diversification in the highlands of upper northern Thailand and the accompanying dismissal of self-subsistence are documented based on the findings from seven case studies carried out in different agricultural and social situations during the past decade. The characteristics of the key driving forces powering this agrarian transition such as rapid economic growth, decrease in the share of labour employed in the agriculture, urbanization and changes in food consumption patterns, and improved communication infrastructures, are presented in the Thai context. The environmental impact of these profound agrarian transformations on the degradation of key renewable resources, particularly soil erosion, is assessed. Their socio-economic consequences on an extensive differentiation among farming households and equity issues are also discussed. Finally the authors draw several lessons from this Thai experience that illustrate the very strong adaptive capacity of small highland farmers. They could be useful in similar agro-ecological zones of neighbouring countries that are presently experiencing the same kind of agricultural transition in the Montane Mainland Southeast Asia ecoregion. Particularly, the article underlines the need for more holistic and integrated approaches to agricultural development and the management of renewable resources in highland agro-ecosystems to alleviate poverty while conserving the resource base.

    Popular summary: Atmospheric aerosols play an important role in the Earth's climate system, and can also have adverse effects on air quality and human health. The environmental impacts of aerosols, on the other hand, are highly regional, since their temporal/spatial distribution is inhomogeneous and highly depends on the regional emission sources. To better understand the effects of aerosols, intensive field experiments are necessary to characterize the chemical and physical properties on a region-by-region basis. From late February to early May in 2006, NASA/GSFC's SMARTLabs facility was deployed at a rural site in central Thailand, Southeast Asia, to conduct a field experiment dubbed BASE-ASIA (Biomass-burning Aerosols in South East-Asia: Smoke Impact Assessment). The group was joined by scientists from the University of Hawaii and other regional institutes. Comprehensive measurements were made during the experiment, including aerosol chemical composition, optical and microphysical properties, as well as surface energetics and local . meteorology. This study analyzes part of the data from the BASE-ASIA experiment. It was found that, even for the relatively remote rural site, the aerosol loading was still substantial. Besides agricultural burning in the area, industrial pollution near the Bangkok metropolitan area, about 200 km southeast of the site, and even long-range transport from China, also contribute to the area's aerosol loading. The results indicate that aerosol pollution has developed into a regional problem for northern Indochina, and may become more severe as the region's population and economy continue to grow. Abstract: Comprehensive measurements of atmospheric aerosols were made in Phimai, central Thailand (15.l83 N, 102.565 E, elevation: 206 m) during the BASE-ASIA field experiment from late February to early May in 2006. The observed aerosol loading was sizable for this rural site (mean aerosol scattering: 108 +/- 64 Mm(exp -1); absorption: 15

    We studied local knowledge and actual uses of medicinal plants among the Mien in northern Thailand, documenting traditional medical practices and its transfer between generations. With the assumption that discrepancies between knowledge and actual use represent knowledge erosion, we studied whether actual use of medicinal plants corresponded to people's knowledge of such uses. We used local knowledge from four specialist informants as the domain for semi-structured interviews with 34 randomly selected non-specialist informants. We calculated informant consensus, use value, and fidelity level for each species and use category and performed statistical analyses with Kolmogorov-Smirnov tests, Pearson correlation coefficient, Spearman's rank correlation coefficient, and paired-sample t-tests. We found significant discrepancies between knowledge and actual use of medicinal plants. The number of known and actually used plants increased with increasing informant age and decreased with increasing years of formal education. Medicinal plant knowledge and use in these Mien communities is undergoing inter-generational erosion because of acculturation and interrupted knowledge transmission. Preservation of Mien medicinal plant intellectual heritage requires continued documentation concerning use, conservation, and sustainable management of this resource, which should be publicized to younger Mien.

    To clarify the diversity of Bacillus subtilis strains in Thua nao that produce high concentrations of products useful in food manufacturing and in health-promoting compounds. Production of amylase, protease, subtilisin NAT (nattokinase), and gamma-polyglutamic acid (PGA) by the Bacillus subtilis strains in Thua nao was measured. Productivity of protease NAT by these strains tended to be higher than by Japanese commercial natto-producing strains. Molecular diversity of isolated strains was analysed via randomly amplified polymorphic DNA-PCR fingerprinting. The strains were divided into 19 types, including a type with the same pattern as a Japanese natto-producing strain. B. subtilis strains that could be a resource for effective production of protease, amylase, subtilisin NAT, or PGA were evident in Thua nao produced in various regions in northern Thailand. This study clearly demonstrated the value of Thua nao as a potential resource of food-processing enzymes and health-promoting compounds.

    1985-01-01

    The IURBP Orientation Phase Mission assesses the Speculative Uranium Resources in Thailand to be within the range of 1 500 to 38 500 tonnes U. Geological environments which are considered by the Mission to be favourable for uranium occurrences include the following: sandstones of Jurassic to Triassic age; Tertiary sedimentary basins (northern Thailand); Tertiary sedimentary basins (southern Thailand); associated with fluorite deposits; granitic rocks; black shales and graphitic slates of the Palaeozoic; associated with sedimentary phosphate deposits; and associated with monazite sands. Physical conditions in Thailand, including a wet tropical climate, dense forest growth and rugged terrain in some areas and relative inaccessibility, make exploration difficult and costly. There is currently no ready accessibility to detailed topographic and geological maps and other basic data. This lack of availability is a severe constraint to systematic exploration. The lack of skilled personnel experienced in uranium studies and the low level of technical support is a serious hindrance to exploration in Thailand. (author)

    Currently, in rural communities from the Peruvian northern coast, it is common to find a climate of distrust and pessimism that accompanies the lack of coordinated social action and community participation among residents. This study analyzes the relationships that people develop with regard to the place where they live in, how it associates to the ways they participate in their community and the relationship that these two variables have with the perceived emotional climate, in a rural community from the northern coast of Peru (n = 81). Results indicate that place identity is significantly associated with a high community participation and a climate of trust in the community. Finally, a Path Analysis is performed to analyze comprehensively the relationship between these variables. The results suggest that place identity does have an influence on perceived positive climate in the community, being mediated by the dimensions of community participation.

    Paragonimiasis is an important food-borne parasitic zoonosis caused by infection with lung flukes of the genus Paragonimus. Of the 7 members of the genus known in Thailand until recently, only P. heterotremus has been confirmed as causing human disease. An 8th species, P. pseudoheterotremus, has recently been proposed from Thailand, and has been found in humans. Molecular data place this species as a sister species to P. heterotremus, and it is likely that P. pseudoheterotremus is not specifically distinct from P. heterotremus. In this study, we collected metacercariae of both nominal species (identification based on metacercarial morphology) from freshwater crabs from Phetchabun Province in northern Thailand, Saraburi Province in central Thailand, and Surat Thani Province in southern Thailand. In addition, we purchased freshwater crabs imported from Myanmar at Myawaddy Province, western Thailand, close to the Myanmar-Thailand border. The DNAs extracted from excysted metacercariae were PCR-amplified and sequenced for ITS2 and cox1 genes. The ITS2 sequences were nearly identical among all samples (99-100%). Phylogenies inferred from all available partial cox1 sequences contained several clusters. Sequences from Indian P. heterotremus formed a sister group to sequences from P. pseudoheterotremus-type metacercariae. Sequences of P. heterotremus from Thailand, Vietnam, and China formed a separate distinct clade. One metacercaria from Phitsanulok Province was distinct from all others. There is clearly considerable genetic variation in the P. heterotremus complex in Thailand and the form referred to as P. pseudoheterotremus is widely distributed in Thailand and the Thai-Myanmar border region.

    Full Text Available Abstract Background The prevalence of methamphetamine use and human immunodeficiency virus (HIV incidence are high in lowland Thai society. Despite increasing social and cultural mixing among residents of highland and lowland Thai societies, however, little is known about methamphetamine use among ethnic minority villagers in the highlands. Methods A cross-sectional survey examined Karen villagers from a developed and a less-developed village on February 24 and March 26, 2003 to evaluate the prevalence and social correlates of methamphetamine use in northern Thailand. Data were collected in face-to-face interviews using a structured questionnaire. Results The response rate was 79.3% (n = 548. In all, 9.9% (males 17.6%, females 1.7% of villagers reported methamphetamine use in the previous year. Methamphetamine was used mostly by males and was significantly related to primary or lower education; to ever having worked in town; to having used opium, marijuana, or heroin in the past year; and to ever having been diagnosed with a sexually transmitted infection (STI. Conclusion Since labor migration to towns is increasingly common among ethnic minorities, the prevention of methamphetamine use and of HIV/STI infection among methamphetamine users should be prioritized to prevent HIV in this minority population in Thailand.

    Background Uganda’s rapid population growth (3.2%) since 1948 has placed more demands on health sector and lowered living standard of Ugandans resulting into 49% of people living in acute poverty especially in post conflict Northern Uganda. The population rise was due to low use of contraceptive methods (21% in rural areas and 43% in urban areas) and coupled with high unmet need for family planning (41%). This indicated poor access to reproductive health services. Effective use of family planning could reduce the rapid population growth. Objective To determine obstacles to family planning use among rural women in Northern Uganda. Design A descriptive cross-sectional analytical study.

Subjects Four hundred and twenty four females of reproductive ages were selected from both Inpatient and Outpatient Departments of Atiak Health Centre IV. Results There was high level of awareness 418 (98.6%), positive attitude 333 (78.6%) and fair level of utilisation 230 (54.2%) of family planning. However, significant obstacles to family planning usage included; long distance to Health facility, unavailability of preferred contraceptive methods, absenteeism of family planning providers, high cost of managing side effects, desire for big family size, children dying less than five years old, husbands forbidding women from using family planning and lack of community leaders’ involvement in family planning programme. Conclusions In spites of the high level of awareness, positive attitude, and free family planning services, there were obstacles that hindered family planning usage among these rural women. However, taking services close to people, reducing number of children dying before their fifth birthday, educating men about family planning, making sure family planning providers and methods are available, reducing cost of managing side effects and involving community leaders will improve utilisation of family

    High levels of depressive symptoms often occur among individuals that use or that are dependent on methamphetamine (MA). Thailand is currently experiencing an epidemic of MA use among youth. Understanding the nature of the relationship between depressive symptoms and MA use and identifying those most at risk can further understanding of prevention and treatment options for youth who use MA and present with depressive symptoms. In 2011, we conducted a cross sectional epidemiologic study that examined associations between MA use and high levels of depressive symptoms among adolescents and young adults aged 14-29 living in Chiang Mai province, Thailand. A combination of cluster and systematic sampling was conducted to obtain a study sample of participants actively recruited in Chiang Mai province. Depressive symptoms were measured using a Thai translation of the Centers for Epidemiologic Studies Depression scale (CES-D). The independent variables measured reported lifetime and recent MA use within the past 3 months. Multivariate logistic regression models were used to assess associations between MA use and high levels of depressive symptoms. Approximately 19% (n = 394) of the sample reported ever having consumed MA and 31% (n = 124) of lifetime users reported recent MA use within the past 3 months. Recent MA use was associated with high levels of depressive symptoms (aPOR recent use: 2.60, 95% CI: 1.20, 5.63). This is one of the first studies to examine the association between MA use and high levels of depressive symptoms in a general Thai population. The odds of having high levels of depressive symptoms was significantly greater among recent MA users compared to non-users. These findings support the need for policies, programs and interventions to prevent and treat depressive symptoms presenting among MA using Thai adolescents and young adults in rural Chiang Mai province, Thailand to aid in cessation of MA use. Furthermore, additional research is needed to

As little is known about HPV in this group in northern Thailand, we studied MSM subgroups comprised of gay men (GM, bisexual men (BM, and transgender women (TGW.From July 2012 through January 2013, 85 (42.5% of 200 GM, 30 (15% BM, and 85 (42.5% TGW who practiced receptive anal intercourse were recruited after informed consent, followed by self-assisted computer interview, HIV testing, and anal swabs for HPV genotyping.Of 197 adequate specimens, the overall prevalence of any HPV was 157 (80%. Prevalence was 89% (76/85 in GM, 48% (14/29 in BM, and 81% (67/83 in TGW. The most common high-risk types were HPV16 (27% of 197, HPV58 (23%, and HPV51 (18%. Prevalence of high-risk types was 74% in 85 GM, 35% in 29 BM, and 71% in 83 TGW. Prevalence of any HPV type, or high-risk type, was 100% and 94%, respectively, among 48 HIV+ MSM, 70% and 54% among 120 HIV- MSM. Of the 197 specimens, 36% (70 had HPV types 16 and/or 18 in the bivalent vaccine, compared to 48% (95 with ≥1 of types 16/18/06/11 in the quadrivalent, 56% (111 for 16/18/31/33/45/52/58 in the 7-valent, and 64% (126 for 16/18/31/33/45/52/58/06/11 in the 9-valent. HIV+, GM, and TGW were independently associated with HPV infection.We found higher rates of both any HPV and high-risk types than previous studies. Among the heretofore unstudied TGW, their equivalent HPV rates were comparable to GM. Current and investigational HPV vaccines could substantially protect GM, BM, and TGW from the serious consequences of HPV infection especially among HIV + MSM.

    Full Text Available Objective: To study the prevalence and risk factors of intestinal parasitic infections among hill tribe schoolchildren who attended 10 border patrol police schools in 2012, Chiang Rai, Thailand. Methods: A total of 339 subjects were recruited into the study from 2 194 children. Questionnaire was tested for validity and reliability before use. About 5 g stool specimens were collected and investigated for intestinal parasite infections by using cellophane-covered thick smear technique. Logistic regression at α = 0.05 was used to test the associations between variables to find risk factors. Results: There were 339 subjects of whom 51.9% were males and 66.1% were Buddhist; racially 31.2% were Akha and 30.4% were Kmong; mean age was 10.3 years old (minimum = 6, maximum = 16. The prevalence of parasitic infection was 9.7%. After controlling for age, sex, religion, parents’ education levels and parents’ occupations, the only factor that showed a statistically significant association with intestinal parasitic infection was the source of drinking water. The group of drinking mountain piped water had a greater risk of 8.22 times (adjusted odds ratio = 8.22, 95%; confidence interval: 1.07–63.18 compared to the drinking commercially bottled water group, while the group of drinking underground water had a greater risk of 9.83 times (adjusted odds ratio = 9.83, 95%; confidence interval: 0.93–104.12 compared to the drinking commercially bottled water group. Conclusions: Drinking water contaminated by soil was shown to be an important risk factor for intestinal parasitic infection in hill tribe schoolchildren living in mountainous border areas in the northern part of Thailand. Safer alternative drinking water source should be provided along with health education for schools and villagers to be aware of the risk of intestinal parasites from drinking water sources such as mountain piped or underground wells. Such sources are likely to contain higher soil

    The current emphasis on skilled attendants as a means to reduce maternal mortality contributes to a discouraging policy environment for traditional birth attendants (TBAs). They continue to attend a significant number of births, however, such that their role and the policies and practices affecting their work remain important to understanding maternity health care and maternal health in the global South. In this article, I examine the policies and practices governing community elders practicing as TBAs in rural northern Uganda. This discussion is relevant to health workers in developing countries and to scholars in fields such as women's studies, sociology, and public health.

    Peat swamp forest in Thailand occurs extensively along coastal flatlands in the central and southern parts of the country and some small patches of topogenous peatland are present locally on several mountain tops of the northern region. Many have been deteriorated by recent extensive development programs. However, one large area, about 347.04 km{sup 2}, of ombrogenous peatland is still left intact in the Pru Toh Dang area where conservation activities are being strictly enforced under one of the Royal Initiative Projects. Pru Toh Dang peat consists of 5 metres of fibrous organic soil overlying pyritic marine clay. Despite an inhospitable, submerged and unstable forest floor, the floristic composition of the peat swamp forest is extremely complicated, consisting of 124 families and 470 species of which 109 families and 437 species of flowering plants, and 15 families and 33 species of ferns recorded between 1983-1989 by a team from the Forest Herbarium of the Royal Forest Department of Thailand.

This study aimed to evaluate knowledge of diabetes, risk factors, and the common warning signs of diabetes and complications among community participants in a rural Karen ethnic community.Methods: Participants were asked to answer a questionnaire regarding their knowledge of diabetes. Fasting blood glucose testing, blood pressure measurement, and body mass index (BMI assessment were provided to the participants. The study was conducted at Thasongyang district, Tak province, Thailand.Results: A total of 299 Karen rural residents were included in the study. The median age was 45 years and median fasting blood glucose was 88 mg/dL. The response rate to the questionnaires was 91.97%. Half of the participants knew diabetes is a noncommunicable disease needing lifelong treatment. Overall, one-third of the community participants could correctly answer the knowledge assessment questions regarding risk factors and common features of diabetes. Whereas the other two-thirds either gave a wrong answer or were “not sure”. Female participants had poorer diabetes knowledge than the males.Conclusion: The public knowledge of diabetes, as represented by this sample of the Karen ethic community, is alarmingly low. There is significant gender difference in knowledge level. Culturally tailored and gender-sensitive diabetes health education interventions are urgently needed in this minority ethnic community.Keywords: health education, gender differences, ethnic minority, diabetes, Karen

    We address a long hypothesized relationship between the proximity of individuals' dwelling units and their kinship association. Better understanding this relationship is important because of its implications for contact and association among members of a society. In this paper, we use a unique dataset from Nang Rong, Thailand which contains dwelling unit locations (GPS) and saturated kinship networks of all individuals living in 51 agricultural villages. After presenting arguments for a relationship between individuals’ dwelling unit locations and their kinship relations as well as the particulars of our case study, we introduce the data and describe our analytic approach. We analyze how kinship - considered as both a system linking collections of individuals in an extended kinship network and as dyadic links between pairs of individuals -patterns the proximity of dwelling units in rural villages. The results show that in general, extended kin live closer to one another than do unrelated individuals. Further, the degree of relatedness between kin correlates with the distance between their dwelling units. Close kin are more likely to co-reside, a fact which drives much of the relationship between kinship relatedness and dwelling unit proximity within villages. There is nevertheless suggestive evidence of a relationship between kinship association and dwelling unit proximity among kin who do not live together. PMID:23956489

  13. Melioidosis in Thailand: Present and Future

    2018-04-01

    Full Text Available A recent modelling study estimated that there are 2800 deaths due to melioidosis in Thailand yearly. The Thailand Melioidosis Network (formed in 2012 has been working closely with the Ministry of Public Health (MoPH to investigate and reduce the burden of this disease. Based on updated data, the incidence of melioidosis is still high in Northeast Thailand. More than 2000 culture-confirmed cases of melioidosis are diagnosed in general hospitals with microbiology laboratories in this region each year. The mortality rate is around 35%. Melioidosis is endemic throughout Thailand, but it is still not uncommon that microbiological facilities misidentify Burkholderia pseudomallei as a contaminant or another organism. Disease awareness is low, and people in rural areas neither wear boots nor boil water before drinking to protect themselves from acquiring B. pseudomallei. Previously, about 10 melioidosis deaths were formally reported to the National Notifiable Disease Surveillance System (Report 506 each year, thus limiting priority setting by the MoPH. In 2015, the formally reported number of melioidosis deaths rose to 112, solely because Sunpasithiprasong Hospital, Ubon Ratchathani province, reported its own data (n = 107. Melioidosis is truly an important cause of death in Thailand, and currently reported cases (Report 506 and cases diagnosed at research centers reflect the tip of the iceberg. Laboratory training and communication between clinicians and laboratory personnel are required to improve diagnosis and treatment of melioidosis countrywide. Implementation of rapid diagnostic tests, such as a lateral flow antigen detection assay, with high accuracy even in melioidosis-endemic countries such as Thailand, is critically needed. Reporting of all culture-confirmed melioidosis cases from every hospital with a microbiology laboratory, together with final outcome data, is mandated under the Communicable Diseases Act B.E.2558.

    Full Text Available Abstract Background Abnormal uterine bleeding (AUB is a common problem that affects one in five women during the pre-menopausal years. It is frequently managed by family physicians, especially in northern, rural and isolated areas where severe shortages of gynecologists exist. Methods We surveyed 194 family physicians in northern, rural and isolated areas of Ontario, Canada to determine their educational and resource needs for the management of AUB, with a specific focus on the relevance and feasibility of using clinical practice guidelines (CPGs. Results Most physicians surveyed did not use CPGs for the management of AUB because they did not know that such guidelines existed. The majority were interested in further education on the management of AUB through mailed CPGs and locally held training courses. A major theme among respondents was the need for more timely and effective gynecological referrals. Conclusion A one-page diagnostic and treatment algorithm for AUB would be easy to use and would place minimal restrictions on physician autonomy. As the majority of physicians had Internet access, we recommend emailing and web posting in addition to mailing this algorithm. Local, hands-on courses including options for endometrial biopsy training would also be helpful for northern, rural and isolated physicians, many of whom cannot readily take time away from their practices.

    CONTEXT Migration is feared to be associated with abandonment and depression in older parents "left behind" in rural areas of low- and middle-income countries. OBJECTIVE To test for prospective associations between (1) out-migration of all children and subsequent depression in parents and (2) having a child move back and an improvement in parents' depression. DESIGN A cohort study with a 1-year follow-up. SETTING A population-based study nested in a demographic surveillance site of 100 villages in rural Thailand. Most out-migration is to the capital city. PARTICIPANTS A stratified random sample of 1111 parents 60 years and older (1 per household) drawn from all 100 villages, of whom 960 (86%) provided depression data at follow-up. MAIN OUTCOME MEASURES Scoring 6 or more on the Thai version of the EURO-D depression scale at follow-up. RESULTS Depression prevalence was 22%. At baseline, 155 (16%) had all their children migrated from the district and 806 (84%) had at least 1 child living in the district. Having all children out-migrated at baseline, compared with having none or some children out-migrated, predicted a smaller odds of depression, after controlling for baseline sociodemographic and health measures (odds ratio [OR], 0.43; 95% CI, 0.20-0.92). Having a child move back in the study year was associated with greater odds of depression at follow-up when adjusted for baseline measures (OR, 1.75; 95% CI, 1.04-2.94), although this was no longer significant after adjusting for changes in disability and marital status since baseline (OR, 1.72; 95% CI, 0.99-2.98). CONCLUSIONS Contrary to our hypothesis, parents whose children are not migrants may be at greater risk of depression than those with migrant children. More understanding is needed about the risks for depression in older rural populations and about the effectiveness of interventions.

    Full Text Available Seasonal and daily biting activity patterns, and natural filarial infections of adult black flies attracted to human bait were investigated at Ban Pang Faen, a rural area in Chiang Mai Province in northern Thailand. Collections were carried out twice a month from 06-00 to 18-00 hours from January 2005 to February 2006. Among ten Simulium species collected, S. nodosum and S. asakoae were predominant occupying 57.3% and 37.2% of the total 16, 553 females, respectively. These two predominant species showed different patterns in seasonal abundance: majority of S. nodosum (86.7% were collected in hot season (from mid February to mid May, while most of S. asakoae (74.5% were collected in rainy season (from mid May to mid October. For the daily biting activity, S. nodosum had two patterns: the main one was unimodal with a peak from 17-00 to 18-00, and the other was bimodal and had the major peak from 16-00 to 18-00 and the minor one from 07-00 to 09-00. The pattern of S. asakoae was mostly unimodal with a peak from 06-00 to 10-00. The filarial larvae found in S. nodosum and S. asakoae were morphologically different from each other. The short and thick infective larvae found in S. asakoae differed from all known filarial larvae; it is suggested that they might be a bird parasite, Splendidofilariinae or Lemdaninae. The infection of the mammophilic S. nodosum with large Onchocerca type infective larvae was confirmed in this area. Natural filarial infections were found in each month (except December in either S. nodosum or S. asakoae or in both. Monthly infection rates with all stages of larvae were 0.6-5.0% for S. nodosum, and 1.0-4.0% for S. asakoae. It is suggested that people in this village are exposed to the risk of infection with zoonotic filariae throughout the year.

    Full Text Available Antibiotic resistance patterns of bacterial isolates from both quarter teat-tip swabs and their quarter milk samples were evaluated in smallholder dairy farms in northern Thailand with excessive use of antibiotics (HIGH compared with normal use (NORM. Results from teat-tip swab samples showed that the percentage of Bacillus spp. resistance to overall antibiotics was significantly lower in the NORM group than that of the HIGH group, whereas, the resistance percentage of coagulase-negative staphylococci in the NORM group was higher than that of the HIGH one. The overall mastitis-causing bacteria isolated from milk samples were environmental streptococci (13.8%, coagulase-negative staphylococci (9.9%, Staphylococcus aureus (5.4%, and Corynebacterium bovis (4.5%. Both staphylococci and streptococci had significantly higher percentages of resistance to cloxacillin and oxacillin in the HIGH group when compared to the NORM one. An occurrence of vancomycin-resistant bacteria was also observed in the HIGH group. In conclusion, the smallholder dairy farms with excessive use of antibiotics had a higher probability of antibiotic-resistant pattern than the farms with normal use.

    Top-down industrial development strategies initially dominated the developing world after the second World War but were eventually found to produce inequitable economic growth. For a decade or more, governments and international development agencies have embraced the idea of participatory grass roots development as a potential solution. Here we review Thailand's experience with development strategies and we examine the current focus on participatory approaches. Thai government planning agencies have adopted "people centred development" and a "sufficiency economy", particularly emphasised since the disruptions caused by the 1997 Asian financial crisis. They aim to address the inequitable sharing of the benefits of decades of rapid growth that was particularly unfair for the rural poor. Thai policies aim to decentralise power to the local level, allowing civil society and Non-Governmental Organisations (NGOs) more of a voice in national decision making and promoting sustainable farming practices aimed at enriching rural communities. An example of this change in Thai government policy is the Community Worker Accreditation Scheme which is aiming to develop human resources at the local level by training community based leaders and supporting networks of community organisations. This enables autonomous local development projects led by trained and accredited individuals and groups. The political tensions notable in Thailand at present are part of this modern transition driven by conflicting models of top-down (industrial) development and the bottom-up (participatory) development ideals described above. Once resolved, Thailand will have few obstacles to moving to a new economic level.

    Full Text Available Ecosystem services are highly vulnerable to a number of impacts due to the complex effects of human use of natural resources and subsequent land use change. Assessment of the impact of change in land use with respect to ecosystem services is necessary in order to implement appropriate land uses that enhance ecosystem services. This study analysed the impact of change in land use on ecosystem services using the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST model to map and quantify a set of ecosystem services, namely sediment retention, water yield, carbon stock, and habitat quality, in northern Thailand, which has experienced substantial policy induced land use change. The study also assessed the changes in land use from 1989 to 2013 and their impact on overall ecosystem services using GIS. Increased rubber plantation cultivation and built-up areas resulting in reduced forest cover were the major changes found in land use in the area. The results of the study show a general decrease in ecosystem services for the study period in the watershed, in particular, a negative impact on ecosystem services was observed in agricultural areas. The study findings on spatial and temporal distribution of ecosystem services can help guide the development of appropriate land use options to enhance ecosystem services.

    Comprehensive measurements of atmospheric aerosols were made in Phimai, central Thailand (15.183°N, 102.565°E, elevation: 206 m) during the BASE-ASIA field experiment from late February to early May in 2006. The observed aerosol loading was sizable for this rural site (mean aerosol scattering: 108 ± 64 Mm-1; absorption: 15 ± 8 Mm-1; PM10 concentration: 33 ± 17 μg m-3), and dominated by submicron particles. Major aerosol compounds included carbonaceous (OC: 9.5 ± 3.6 μg m-3; EC: 2.0 ± 2.3 μg m-3) and secondary species (SO42-: 6.4 ± 3.7 μg m-3, NH4+: 2.2 ± 1.3 μg m-3). While the site was seldom under the direct influence of large forest fires to its north, agricultural fires were ubiquitous during the experiment, as suggested by the substantial concentration of K+ (0.56 ± 0.33 μg m-3). Besides biomass burning, aerosols in Phimai during the experiment were also strongly influenced by industrial and vehicular emissions from the Bangkok metropolitan region and long-range transport from southern China. High humidity played an important role in determining the aerosol composition and properties in the region. Sulfate was primarily formed via aqueous phase reactions, and hygroscopic growth could enhance the aerosol light scattering by up to 60%, at the typical morning RH level of 85%. The aerosol single scattering albedo demonstrated distinct diurnal variation, ranging from 0.86 ± 0.04 in the evening to 0.92 ± 0.02 in the morning. This experiment marks the first time such comprehensive characterization of aerosols was made for rural central Thailand. Our results indicate that aerosol pollution has developed into a regional problem for northern Indochina, and may become more severe as the region's population and economy continue to grow.

    In traditional houses in rural areas of Northern China, most traditional heating systems, heated by mini-stove in the kitchen, usually take agricultural residues as fuels resources. Besides, burning cave under the ground-floor of a rural house is also widely used. The higher PM2.5 concentration is crisis for human health. In this study, PM2.5 concentration, temperature, relative humidity inside and outside the houses have been measured, moreover the factors impact on I/O rate coefficient has been discussed. The results show that the I/O rate coefficient in the evening is 2.5 times greater than the I/O rate coefficient in the daytime. I/O rate coefficient of PM2.5 concentration is positive related to air temperature difference between indoor and outdoor. In addition, the impact of outdoor wind speed and predominant wind direction on the PM2.5 emission has been studied.

    Full Text Available Abstract Background High levels of depressive symptoms often occur among individuals that use or that are dependent on methamphetamine (MA. Thailand is currently experiencing an epidemic of MA use among youth. Understanding the nature of the relationship between depressive symptoms and MA use and identifying those most at risk can further understanding of prevention and treatment options for youth who use MA and present with depressive symptoms. Methods In 2011, we conducted a cross sectional epidemiologic study that examined associations between MA use and high levels of depressive symptoms among adolescents and young adults aged 14–29 living in Chiang Mai province, Thailand. A combination of cluster and systematic sampling was conducted to obtain a study sample of participants actively recruited in Chiang Mai province. Depressive symptoms were measured using a Thai translation of the Centers for Epidemiologic Studies Depression scale (CES-D. The independent variables measured reported lifetime and recent MA use within the past 3 months. Multivariate logistic regression models were used to assess associations between MA use and high levels of depressive symptoms. Results Approximately 19 % (n = 394 of the sample reported ever having consumed MA and 31 % (n = 124 of lifetime users reported recent MA use within the past 3 months. Recent MA use was associated with high levels of depressive symptoms (aPOR recent use: 2.60, 95 % CI: 1.20, 5.63. Conclusions This is one of the first studies to examine the association between MA use and high levels of depressive symptoms in a general Thai population. The odds of having high levels of depressive symptoms was significantly greater among recent MA users compared to non-users. These findings support the need for policies, programs and interventions to prevent and treat depressive symptoms presenting among MA using Thai adolescents and young adults in rural Chiang Mai province, Thailand to

    Annual and monthly-based emission inventories in northern, central and north-eastern provinces in Thailand, where agriculture and related agro-industries are very intensive, were estimated to evaluate the contribution of agricultural activity, including crop residue burning, forest fires and related agro-industries on air quality monitored in corresponding provinces. The monthly-based emission inventories of air pollutants, or, particulate matter (PM), NOx and SO 2 , for various agricultural crops were estimated based on information on the level of production of typical crops: rice, corn, sugarcane, cassava, soybeans and potatoes using emission factors and other parameters related to country-specific values taking into account crop type and the local residue burning period. The estimated monthly emission inventory was compared with air monitoring data obtained at monitoring stations operated by the Pollution Control Department, Thailand (PCD) for validating the estimated emission inventory. The agro-industry that has the greatest impact on the regions being evaluated, is the sugar processing industry, which uses sugarcane as a raw material and its residue as fuel for the boiler. The backward trajectory analysis of the air mass arriving at the PCD station was calculated to confirm this influence. For the provinces being evaluated which are located in the upper northern, lower northern and northeast in Thailand, agricultural activities and forest fires were shown to be closely correlated to the ambient PM concentration while their contribution to the production of gaseous pollutants is much less.

    Full Text Available Anal cancer, one of human papillomavirus (HPV related malignancies, has increased in recent decades, particularly among men who have sex with men (MSM and HIV-infected (HIV+ persons. We aimed to explore the prevalence of anal squamous intraepithelial lesions (ASIL using Papanicolau (Pap screening among MSM in northern Thailand and its associated factors.Two hundreds MSM aged ≥18 years reporting receptive anal intercourse in the prior 6 months were recruited from July 2012 through January 2013. Medical history and behavioral data were collected by staff interview and computer-assisted self interview. Anal Pap smear, HPV genotyping, and HIV testing were performed. Two pathologists blinded to HPV and HIV status reported cytologic results by Bethesda classification.Mean age was 27.2 years (range 18-54. Overall, 86 (43.0% had ASIL: 28 (14.2% with atypical cells of undetermined significance (ASCUS, 1 (0.5% with atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H, 56 (28.4% with low-grade squamous intraepithelial lesion (LSIL, and 1 (0.5% with high-grade squamous intraepithelial lesion (HSIL. ASIL was associated by univariate analysis (p ≤0.05 with older age, gender identity other than bisexual (i.e., gay men and transgender women, rectal douching, anal symptoms, genital warts, HIV positivity, and high-risk-HPV infection.

    Anal cancer, one of human papillomavirus (HPV) related malignancies, has increased in recent decades, particularly among men who have sex with men (MSM) and HIV-infected (HIV+) persons. We aimed to explore the prevalence of anal squamous intraepithelial lesions (ASIL) using Papanicolau (Pap) screening among MSM in northern Thailand and its associated factors. Two hundreds MSM aged ≥18 years reporting receptive anal intercourse in the prior 6 months were recruited from July 2012 through January 2013. Medical history and behavioral data were collected by staff interview and computer-assisted self interview. Anal Pap smear, HPV genotyping, and HIV testing were performed. Two pathologists blinded to HPV and HIV status reported cytologic results by Bethesda classification. Mean age was 27.2 years (range 18-54). Overall, 86 (43.0%) had ASIL: 28 (14.2%) with atypical cells of undetermined significance (ASCUS), 1 (0.5%) with atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H), 56 (28.4%) with low-grade squamous intraepithelial lesion (LSIL), and 1 (0.5%) with high-grade squamous intraepithelial lesion (HSIL). ASIL was associated by univariate analysis (p ≤0.05) with older age, gender identity other than bisexual (i.e., gay men and transgender women), rectal douching, anal symptoms, genital warts, HIV positivity, and high-risk-HPV infection. However, on multiple logistic regression ASIL was associated only with high-risk HPV type (p = 0.002) and HIV infection (p = 0.01). ASIL is quite common in high-risk MSM in northern Thailand and is associated with high-risk HPV types and HIV infection. Routine anal Pap screening should be considered, given the high frequency of ASIL, particularly in the HIV+. High resolution anoscopy (HRA), not done here, should be to confirm PAP smears whose sensitivity and specificity are quite variable. Timely HPV vaccination should be considered for this population.

    Full Text Available The origin of tropical cyclones in the South China Sea is over a vast deep sea, southeast of the Philippines. The severetropical cyclones in summer with northerly tracks attack the Philippines, China, Korea and Japan, while the moderate ones inthe rainy season with northwesterly tracks pass Vietnam, Laos and northern Thailand. In October, November and December, the tropical cyclones are weakened and tracks shift to a lower latitude passing the Gulf of Thailand. Tropical cyclone disasters in the Gulf of Thailand due to strong winds causing storm surges and big waves or heavy rainfall over high mountains in causing floods and land slides result in moderate damages and casualties. Analyses are made of six decades of data of tropical cyclones from 1951-2006 having averaged numbers of 3 and 13 in Thailand and the South China Sea respectively. Detailed calculation of surges and wave heights of the 5 disastrous tropical cyclones in the Gulf of Thailand reveal that the Upper Gulf of Thailand with a limited fetch length of about 100 km in north/south direction and about 100 km width in the east/west direction, resulted in a limited maximum wave height of 2.3-2.5 m and maximum storm surge height of 1.2 m generated by Typhoon Vae (1952, while the east coast, with longer fetch lengthbut still limited by the existence of its shoreline, resulted in an increased maximum wave height of 4 m and maximum storm surge height of 0.6 m in the Upper Gulf of Thailand generated by Typhoon Linda (1997. These are the Probable Maximum Cyclones here.The southern shoreline, with unlimited fetch length on the east by tropical cyclones approaching from the South China Sea, generated maximum wave height of 6-11 m by Typhoon Gay (1989, resulting in more casualties and damages. Note that storm surges on the southern shorelines with steep slopes are small due to the short distance of shallow shorelines in receiving wind stresses for piling up sea levels. These disasters can be

    Blood transfusion in rural sub-Saharan Africa presents special challenges. Transfusions are primarily given for emergencies--life-threatening blood loss or anemia; blood is usually collected from family or replacement donors; and facilities to store an adequate reserve in a hospital bank are constrained. We report the everyday and organizational practices in a medium-sized district hospital in Northern Ghana. Information and data on blood transfusion practices at West Gonja Hospital, Damongo, were available from the laboratory reports, from day books and workbooks, and from direct observation in the following four areas: blood collection and blood donors; blood donation testing; blood storage and logistics; and clinical transfusion practice, adverse events, and follow-up. The hospital serves a rural community of 86,000. In 2009, a total of 719 units of whole blood were collected, a rate of 8.36 units per 1000 population. All donors were family or replacement donors. Positivity rates for infectious disease markers were 7.5% (64/853) for hepatitis B surface antigen, 6.1% (50/819) for hepatitis C virus, 3.9% (33/846) for human immunodeficiency virus, and 4.7% (22/468) for syphilis. Supply of laboratory materials was sometimes problematic, especially for temperature-critical materials. Difficulties in sample labeling, storage of blood and laboratory supplies, and disposal of waste were also incurred by operational, material, and financial constraints. Follow-up for outcomes of transfusion is not currently feasible. The operational, demographic, and financial environment pertaining in a rural hospital in Northern Ghana differs substantially from that in which much of current blood transfusion practice and technology evolved. Considerable effort and innovation will be needed to address successfully the challenges posed. © 2012 American Association of Blood Banks.

    Full Text Available Abstract Decades of neglect and abuses by the Burmese government have decimated the health of the peoples of Burma, particularly along her eastern frontiers, overwhelmingly populated by ethnic minorities such as the Shan. Vast areas of traditional Shan homelands have been systematically depopulated by the Burmese military regime as part of its counter-insurgency policy, which also employs widespread abuses of civilians by Burmese soldiers, including rape, torture, and extrajudicial executions. These abuses, coupled with Burmese government economic mismanagement which has further entrenched already pervasive poverty in rural Burma, have spawned a humanitarian catastrophe, forcing hundreds of thousands of ethnic Shan villagers to flee their homes for Thailand. In Thailand, they are denied refugee status and its legal protections, living at constant risk for arrest and deportation. Classified as "economic migrants," many are forced to work in exploitative conditions, including in the Thai sex industry, and Shan migrants often lack access to basic health services in Thailand. Available health data on Shan migrants in Thailand already indicates that this population bears a disproportionately high burden of infectious diseases, particularly HIV, tuberculosis, lymphatic filariasis, and some vaccine-preventable illnesses, undermining progress made by Thailand's public health system in controlling such entities. The ongoing failure to address the root political causes of migration and poor health in eastern Burma, coupled with the many barriers to accessing health programs in Thailand by undocumented migrants, particularly the Shan, virtually guarantees Thailand's inability to sustainably control many infectious disease entities, especially along her borders with Burma.

    Full Text Available Background: Incense and joss stick are generally used in the world. Most products were made in small household factories. There are many environmental and occupational hazards in these factories. Objective: To evaluate the workplace environmental and occupational hazards in small household incense and joss stick factories in Roi-Et, Thailand. Methods: Nine small household factories in rural areas of Roi-Et, Thailand, were studied. Dust concentration and small aerosol particles were counted through real time exposure monitoring. The inductively coupled plasma optical emission spectrometry (ICP-OES was used for quantitative measurement of heavy metal residue in incense products. Results: Several heavy metals were found in dissolved dye and joss sticks. Those included barium, manganese, and lead. Rolling and shaking processes produced the highest concentration of dust and aerosols. Only 3.9 % of female workers used personal protection equipment. Conclusion: Dust and chemicals were major threats in small household incense and joss stick factories in Thailand. Increasing awareness towards using personal protection equipment and emphasis on elimination of environmental workplace hazards should be considered to help the workers of this industry.

    Three hundred and thirty three patients in the lathyrism endemic rural Estie district of Northern Ethiopia were interviewed and examined to assess the psychosocial impacts of neurolathyrism. The majority of the affected were in the age group of 11-20 years (43%) followed by 21-30 years (29%). Males were more affected than females (4.8:1). Peak occurrences of neurolathyrism was observed at time of mobilization of the population in villagization and land diversification schemes. Females were affected to lesser extent and at an earlier age than males. Neurolathyrism affected matrimony among the rural farming population where marriage is considered as the most significant social achievement of any young member of the society. Divorce rate due to paralysis was 28%. It also influenced the choice of occupation among the afflicted rural people. Many males went into ecclesiastical professions. A significant number of males also took up occupations which traditionally were considered to be exclusively for women like basketry and embroidery. More females, not withstanding their age, were engaged in cattle-keeping. During the study, the rural communities were made aware of the association of neurolathyrism and consumptions of grass pea seed. It is believed that this step will enable communities to use home-based detoxifying methods and resort to alternate crops during times of food shortage.

  17. A Linear Dynamical Systems Approach to Streamflow Reconstruction Reveals History of Regime Shifts in Northern Thailand

    Nguyen, Hung T. T.; Galelli, Stefano

    2018-03-01

    Catchment dynamics is not often modeled in streamflow reconstruction studies; yet, the streamflow generation process depends on both catchment state and climatic inputs. To explicitly account for this interaction, we contribute a linear dynamic model, in which streamflow is a function of both catchment state (i.e., wet/dry) and paleoclimatic proxies. The model is learned using a novel variant of the Expectation-Maximization algorithm, and it is used with a paleo drought record—the Monsoon Asia Drought Atlas—to reconstruct 406 years of streamflow for the Ping River (northern Thailand). Results for the instrumental period show that the dynamic model has higher accuracy than conventional linear regression; all performance scores improve by 45-497%. Furthermore, the reconstructed trajectory of the state variable provides valuable insights about the catchment history—e.g., regime-like behavior—thereby complementing the information contained in the reconstructed streamflow time series. The proposed technique can replace linear regression, since it only requires information on streamflow and climatic proxies (e.g., tree-rings, drought indices); furthermore, it is capable of readily generating stochastic streamflow replicates. With a marginal increase in computational requirements, the dynamic model brings more desirable features and value to streamflow reconstructions.

    Present development of radiation utilization in Thailand covers two main areas, i.e. (1) production and utilization of radioisotopes and (2) radiation processing and technology. Radioisotope production from 2 megawatts Thai Research Reactor (TRR1/M1) is being studied, directed toward expanding the varieties of radioisotopes, improvement of quality, and technological development on quantity producing to meet the total national needs. However a large amount of radioisotopes is also imported mainly for industrial and medical applications. Radioisotopes and radiations are utilized in nuclear medicine for diagnosis and therapy from 30 hospitals and institutions. X-ray photographing, X-ray computer tomography and others are typical use for medical examination purposes, while Co-60 gamma rays and electron beam are in used for curing. Since 1972, Thailand has been participated to the IAEA/RCA Industrial Project, through the liaison of the Office of Atomic Energy for Peace (OAEP), and increases the awareness of industry to the economic benefits through the uses of nuclear technology. More than 60 companies are using radioisotopes for gauging, examination purposes and production controls, while these radioisotopes are mostly imported. Nuclear techniques in agriculture are addressed concerns with optimizing fertilizer application, determination soil-water-nitrogen fixation relationships, improving animal health and reproduction, measurement of toxic residues, appropriated food preservation techniques and breeding plant for better yield and disease resistance. The eradication of fruit flies by Sterile Insect Technique (SIT) with gamma rays has been successfully applied in northern and middle part of Thailand. The progress and present status of radiation utilization and processing in Thailand will be introduced. (author)

    The objectives of this study are to survey the antibiotic-resistant pattern of Helicobacter pylori infection in different geographical locations in Thailand and to determine factors associated with antibiotic resistance. Dyspeptic patients undergoing upper gastrointestinal endoscopy from the Northern, Northeastern, Central, and Southern regions of Thailand between January 2004 and December 2012 were enrolled in this study. Two antral gastric biopsies were obtained for culture; susceptibility tests were performed using E-test. A total of 3964 were enrolled, and 1350 patients (34.1%) were infected with H. pylori as identified by rapid urease test. Cultures were positive in 619 isolates. E-test for amoxicillin, clarithromycin, metronidazole, and tetracycline were successful in 400 isolates and for levofloxacin and ciprofloxacin in 208 isolates. Antibiotic resistance was present in 50.3% including amoxicillin 5.2%, tetracycline 1.7%, clarithromycin 3.7%, metronidazole 36%, ciprofloxacin 7.7%, levofloxacin 7.2%, and multi-drugs in 4.2%. Clarithromycin resistance was significantly more common in those older than 40 years (i.e., 100% versus 0%; P = 0.04). The prevalence of metronidazole resistant in Southern Thailand was significantly higher than in the Northeastern region (66.7% versus 33.3% P = 0.04). Metronidazole resistance remains the most common antibiotic resistant type of H. pylori in Thailand. The pattern of H. pylori antibiotic resistance over 9 years demonstrated a fall in clarithromycin resistance such that currently age >40 years is a predictor for clarithromycin resistance in Thailand. Quinolone resistance is a growing problem. © 2013.

    AbstractRickettsial infections are recognized as important causes of fever throughout southeast Asia. Herein, we determined the seroprevalence to rickettsioses within rural and urban populations of northern Vietnam. Prevalence of individuals with evidence of prior rickettsial infections (IgG positive) was surprisingly low, with 9.14% (83/908) testing positive to the three major rickettsial serogroups thought to circulate in the region. Prevalence of typhus group rickettsiae (TG)-specific antibodies (6.5%, 58/908) was significantly greater than scrub typhus group orientiae (STG)- or spotted fever group rickettsiae (SFG)-specific antibodies ( P < 0.05). The majority of TG seropositives were observed among urban rather than rural residents ( P < 0.05). In contrast, overall antibody prevalence to STG and SFG were both very low (1.1%, 10/908 for STG; 1.7%, 15/908 for SFG), with no significant differences between rural and urban residents. These results provide data on baseline population characteristics that may help inform development of Rickettsia serological testing criteria in future clinical studies.

    Livestock fulfill different functions. Depending on their livelihood strategies, households differ in their choice of what type of animal to keep and on accumulation of the chosen animal overtime. Using a panel data of 385 rural households in a mixed farming system in northern Ethiopia, this paper investigates the dynamic behavior of rural households' livestock holding to identify determinants of choice and accumulation of livestock overtime. Choice is analyzed for a principal animal, the animal that constituted the largest value of livestock assets a household possessed, using a multinomial logit model. Results indicate that rural households differ in their choice of what type of animal to keep. Agro-climatic conditions, sex and age of household head, presence of an adult male member in a household, and liquidity are the major factors that influence the type of principal animal households keep. Conditional on the principal animal selected, we analyzed the factors that determine the accumulation of the chosen animals by correcting for selection bias. Area of land cultivated is the most significant factor that explains the number of animals households keep. Other factors include sex of household head, diversification into nonfarm self-employment, and shocks.

    Background This project is part of the prospective quasi experimental proof-of-concept investigation of clinical pharmacist intervention study to reduce drug-related problems among people admitted to a ward in a rural hospital in northern Sweden. Objective To explore doctors' and nurses' perceptions and expectations of having a ward-based pharmacist providing clinical pharmacy services. Setting Medical ward in a rural hospital in northern Sweden. Method Eighteen face-to-face semi-structured interviews were conducted with a purposive sample of doctors and nurses working on the ward where the clinical pharmacy service was due to be implemented. Semi-structured interviews were digitally recorded, transcribed and analysed using thematic analysis. Main outcome measure Perceptions and expectations of nurses and doctors. Results Doctors and nurses had limited experience of working with pharmacists. Most had a vague idea of what pharmacists can contribute within a ward setting. Participants, mainly nurses, suggested inventory and drug distribution roles, but few were aware of the pharmacists' skills and clinical competence. Different views were expressed on whether the new clinical pharmacy service would have an impact on workload. However, most participants took a positive view of having a ward-based pharmacist. Conclusion This study provided an opportunity to explore doctors' and nurses' expectations of the role of clinical pharmacists before a clinical pharmacy service was implemented. To successfully implement a clinical pharmacy service, roles, clinical competence and responsibilities should be clearly described. Furthermore, it is important to focus on collaborative working relationships between doctors, nurses and pharmacists.

    This study aimed to assess the safety, acceptability and feasibility of primary human papillomavirus (HPV) testing for cervical cancer prevention at the community level in a low-resource setting. After training a technician to run specimens on the careHPV unit, the study team traveled to a different village each day in rural Roi-et Province, Thailand. Women were tested for HPV using self-swab, followed by careHPV testing. Those with positive result were assessed immediately by visual inspection with acetic acid. Women positive for HPV and visual inspection with acetic acid were offered cryotherapy. Safety was determined by monitoring adverse events. Exit surveys assessed acceptability and feasibility. Feasibility was also assessed by measuring testing and triage throughputs. Technician training required 2.5 days to achieve competency. A total of 431 women were screened in 14 days, with an average of 31 women screened daily. No adverse events were reported. Women deemed the program overwhelmingly acceptable: 90.5% reported that they would take the self-swab again, 71.3% preferred the self-swab to a clinician swab. The program was also feasible: 99.8% of eligible women agreed to testing, 94.8% returned for same-day follow-up, and women only spent 30 to 50 minutes of their total time with the program from screening to results. Cervical cancer prevention programs based on self-swab HPV testing could be safe, acceptable, feasible, and effective at the community level in low-resource settings.

    In a cross-sectional survey in one rural and one suburban village each in Thailand and Laos the relationship between Aedes aegypti production and Escherichia coli contamination in household water storage containers was investigated. Entomological and microbiological surveys were conducted in 250 and 239 houses in Thailand and Laos, respectively. Entomological indices across all four villages were high, indicating a high risk for dengue transmission. Significantly more Ae. aegypti pupae were produced in containers contaminated with E. coli as compared to those that were not, with the odds of Ae. aegypti infested containers being contaminated with E. coli ranging from two to five. The level of E. coli contamination varied across container classes but contamination levels were not significantly associated with the number of pupae produced. We conclude that the observed relationship between Ae. aegypti production and presence of E. coli in household water storage containers suggests a causal relationship between dengue and diarrheal disease at these sites. How this relationship can be exploited for the combined and cost-effective control of dengue and diarrheal diseases requires further research. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available This study evaluated the effects of culture season and different stocking density on productivity of freshwater prawn that was raised in northern Thailand. The experiment was conducted at the Faculty of Fisheries Technology and Aquatic Resources, Maejo University, Chiang Mai, Thailand. This study was divided into two experiments; each treatment was replicated three times. The first experiment investigated the effect of climatic condition on the culture and production of freshwater prawn post larvae (PL 10; mean weight of 0.02 g stocked in 400m2 ponds. Results of the first experiment revealed freshwater prawn raised during the dry season to summer obtained higher growth rate (0.19 g and 0.15 g/day and survival rate (34.27% and 24.49% than that of summer to rainy season (p<0.05. The second experiment investigated the effect of 2 different socking densities (25 and 50 individuals/m2 on the production survival of freshwater prawn. Results showed that the rate of growth, survival rate, and production, were much higher at a stocking density of 25 individuals/m2 (p<0.05 in contrast to 50 individuals/m2. Growth performances of freshwater prawns were triggered by stocking density and season.

    Full Text Available The aim of the study was to investigate five healthy dietary behaviours in a sample of rural and semi-urban South Africans. The sample consisted of 200 adults, 100 from an semi-urban area (Mankweng and 100 from a rural area (Tiberius in the central region of the Northern Province of South Africa. The two geographically different communities were chosen by convenience and the participants in the two communities were choosen by cluster sampling. Results indicate that about a third (30% in semi-urban and 34% in rural of the study sample are overweight and 18% are obese. A moderately high prevalence of six simple healthy dietary practices was found. However, there was a very low prevalence rate of eating fruits daily among both semi-urban (10% and rural dwellers (9%. Semi-urban dwellers showed significantly higher healthy diet behaviour than rural dwellers in regard to avoiding fat, trying to eat fiber, limiting red meat, and limiting salt. Men reported more than women that they tried to eat fiber and they had more often breakfast everyday. Being semi-urban and female were significantly associated with the healthy dietary index, whereas age, BMI, educational level and marital status were not. The results give insight into dietary health behaviour practices and the factors that influence them, which have practical implications for dietary health promotion.

    Hypertension is currently a global health concern. Rural and minority populations are increasingly exposed to risk factors as a result of urbanization, leading to hypertension and cardiovascular disease. We conducted a survey in the rural Karen community in Thasongyang District, Tak Province, Thailand, with the aims of determining: the distribution of blood pressure across different age groups; the prevalence of hypertension and other risk factors for cardiovascular diseases (CVDs), including diabetes, smoking, sedentary lifestyle, and excess alcohol use; knowledge and awareness of hypertension as a disease; and knowledge and awareness of risk factors for hypertension among the population at risk. This was a community-based, cross-sectional survey of 298 rural Karen residents. A set of questionnaires assessing lifestyle-related health risk behaviors and awareness and knowledge of hypertension were used. Blood pressure, fasting plasma glucose, weight, height, and waist circumference were measured. Median systolic and diastolic blood pressures were 110 (range 100-120) mmHg and 70 (range 60-80) mmHg, respectively. High blood pressure was observed in more than 27% of the population, with 15% being hypertensive and 12% being prehypertensive. Multinomial logistic regression analysis showed that people in the Karen community who were aware of hypertension were less likely to be current smokers (odds ratio [OR] 0.53, confidence interval [CI] 0.29-0.97) and those with primary school education were more likely to be aware of hypertension than those who did not have a primary school education (OR 6.5, CI 1.9-22.24). Overall, our survey showed that less than half of the Karen community had such knowledge and awareness. It is urgently necessary to promote knowledge, awareness, and health literacy among the ethnic Karen tribes to prevent hypertension and associated CVDs.

  9. Late-stage alteration and tin-tungsten mineralization in the Khuntan Batholith, northern Thailand

    The Khuntan Batholith is part of the Triassic-Jurassic eastern marginal belt of the Northern Thailand Granite Province. Most of the batholith consists of coarse-grained, porphyritic to megacrystic biotite-muscovite granite (Huai Mae San unit). However, the southeastern part, called the Muang Yao unit, consists of coarse- to medium-grained muscovite and muscovite-tourmaline granite and is associated with Sn-W mineralization. The Huai Mae San granite has S-type petrological features typical of batholiths in the eastern marginal belt, which formed in a syn-collisional setting. The more silicic Muang Yao granite differs chemically from felsic S-type granite, for example in extreme Rb-Y-Nb enrichment and Ba-Sr-Zr depletion, probably as a result of late-stage fluid alteration. Vein-hosted deposits of cassiterite, scheelite, and wolframite associated with minor sulfides occur in both the Muang Yao granite and adjacent metamorphic rocks. Fluid-inclusion studies indicate that both aqueous and aqueous-carbonic fluids of low salinity (0-8 wt% equiv. NaCl) were involved in vein formation, and were subject to pressure fluctuation between essentially lithostatic and hydrostatic conditions. Dilution of magmatic hydrous fluid by influx of meteoric water may explain the anomalously low salinity. Oxygen isotope data support a primary magmatic origin for the fluid, and indicate temperatures of ca. 400 °C for ore deposition. The three vein-type Sn-W deposits of this study represent a spectrum from an endogranite vein system to proximal-intermediate vein systems of magmatic-hydrothermal origin.

    An age distribution shift in diphtheria cases during a 2012 outbreak in northeastern of Thailand suggests adults are increasingly at risk for infection in Thailand. Data regarding immunity against diphtheria among the adult Thai population is limited. We review a 2012 diphtheria outbreak in Thailand and conducted a nationwide seroepidemiological survey to determine the prevalence of diphtheria antibodies among Thai adults in order to inform immunization programs. A total of 41 confirmed cases, 6 probable cases and 101 carriers of diphtheria were reported from northeastern and upper southern Thailand. The diphtheria outbreak in northeastern Thailand occurred among adults aged > or =15 years; sporadic cases occurred among children from upper southern Thailand. We conducted a seroepidemiological survey of 890 Thai adults from 4 age groups (20-29, 30-39, 40-49 and 50-59 years) in 7 different geographical areas of Thailand (Chiang Mai, Ratchaburi, Chon Buri, Nakhon Si Thammarat, Phitsanulok, Khon Kaen and Songkhla). Diptheria toxin antibody levels were measured with a commercially available ELISA test. The seroprotection rate ranged from 83% to 99%, with the highest in eastern Thailand (Chon Buri, 99%) and the lowest in northern Thailand (Chiang Mai, 83%). Diphtheria antibodies declined with increasing age. We recommend one doseof diphtheria-tetanus toxoid (dT) vaccine once after 20 years of age in order to boost the antibody and revaccinations every 10 years to prevent future outbreaks.

    A pilot, cross-sectional, correlational study was conducted in eight rural communities in northern Nigeria to investigate mycotoxin exposures in 120 volunteers (19 children, 20 adolescents and 81 adults) using a modern LC-MS/MS based multi-biomarker approach. First morning urine samples were analyzed and urinary biomarker levels correlated with mycotoxin levels in foods consumed the day before urine collection. A total of eight analytes were detected in 61/120 (50.8%) of studied urine samples, with ochratoxin A, aflatoxin M1 and fumonisin B1 being the most frequently occurring biomarkers of exposure. These mycotoxin biomarkers were present in samples from all age categories, suggestive of chronic (lifetime) exposures. Rough estimates of mycotoxin intake suggested some exposures were higher than the tolerable daily intake. Overall, rural consumer populations from Nasarawa were more exposed to several mixtures of mycotoxins in their diets relative to those from Kaduna as shown by food and urine biomarker data. This study has shown that mycotoxin co-exposure may be a major public health challenge in rural Nigeria; this calls for urgent intervention. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Ranong Province in southern Thailand is one of the primary entry points for migrants entering Thailand from Myanmar, and borders Kawthaung Township in Myanmar where artemisinin resistance in malaria parasites has been detected. Areas of high population movement could increase the risk of spread of artemisinin resistance in this region and beyond.A respondent-driven sampling (RDS methodology was used to compare migrant populations coming from Myanmar in urban (Site 1 vs. rural (Site 2 settings in Ranong, Thailand. The RDS methodology collected information on knowledge, attitudes, and practices for malaria, travel and occupational histories, as well as social network size and structure. Individuals enrolled were screened for malaria by microscopy, Real Time-PCR, and serology.A total of 619 participants were recruited in Ranong City and 623 participants in Kraburi, a rural sub-district. By PCR, a total of 14 (1.1% samples were positive (2 P. falciparum in Site 1; 10 P. vivax, 1 Pf, and 1 P. malariae in Site 2. PCR analysis demonstrated an overall weighted prevalence of 0.5% (95% CI, 0-1.3% in the urban site and 1.0% (95% CI, 0.5-1.7% in the rural site for all parasite species. PCR positivity did not correlate with serological positivity; however, as expected there was a strong association between antibody prevalence and both age and exposure. Access to long-lasting insecticidal treated nets remains low despite relatively high reported traditional net use among these populations.The low malaria prevalence, relatively smaller networks among migrants in rural settings, and limited frequency of travel to and from other areas of malaria transmission in Myanmar, suggest that the risk for the spread of artemisinin resistance from this area may be limited in these networks currently but may have implications for regional malaria elimination efforts.

    Full Text Available Several Simulium species were investigated as to their biting habits and natural infections with filarial larvae at Ban Pan Fan, Chiang Mai Province, in northern Thailand. Female adults flies landing on or flighting around a human and a water buffalo were collected during the daytime from 06.00 to 19.00 hours on 22 June 2001. As a result, 217 S. nodosum, 86 S. asakoae and two S. nigrogilvum were obtained from a human attractant, and 416 S. nodosum, 25 S. nakhonense, 16 S. asakoae, four 5. fenestratum and two S. nigrogilvum, from a water buffalo. The blood-feeding was confirmed only for S. nodosum and S. nigrogilvum on humans, and for S. nodosum and S. nakhonense on water buffalos. Dissections of these simuliids showed that S. nodosum was naturally infected with developing filarial larvae. Two types of microfilariae were distinguished but only one type of infective larvae. These larvae resembled Onchocerca suzukii, a parasite from a wild Japanese bovid, suggesting that an unknown Onchocerca species from ruminants was transmitted in Thailand. Infection rates with all stages of larvae and third-stage larvae were 2.3 % (14/608 and 1 .0 % (6/608, respectively. This is the first report of natural infections of black flies with Onchocerca larvae in Southeast Asia, and the involved black fly species is shown to be not only anthropophilic but also zoophilic in this region.

    2013-12-01

    Full Text Available Hand, Foot and Mouth Disease (HFMD is an emerging viral disease, and at present, there are no antiviral drugs or vaccines available to control it. Outbreaks have persisted for the past 10 years, particularly in northern Thailand. This study aimed to elucidate the phenomenon of HFMD outbreaks from 2003 to 2012 using general statistics and spatial-temporal analysis employing a GIS-based method. The spatial analysis examined data at the village level to create a map representing the distribution pattern, mean center, standard deviation ellipse and hotspots for each outbreak. A temporal analysis was used to analyze the correlation between monthly case data and meteorological factors. The results indicate that the disease can occur at any time of the year, but appears to peak in the rainy and cold seasons. The distribution of outbreaks exhibited a clustered pattern. Most mean centers and standard deviation ellipses occurred in similar areas. The linear directional mean values of the outbreaks were oriented toward the south. When separated by season, it was found that there was a significant correlation with the direction of the southwest monsoon at the same time. An autocorrelation analysis revealed that hotspots tended to increase even when patient cases subsided. In particular, a new hotspot was found in the recent year in Mae Hong Son province.

The significance, however, of social network diversity in the geriatric assessment of people aged ≥80 years has not been adequately investigated within the Southeast Asian context. This study explored the social networks belonging to the elderly aged ≥80 years and assessed the relation of social network and geriatric depression. Methods: This study was a community-based cross-sectional survey conducted in Chiang Mai Province, Northern Thailand. A representative sample of 435 community residents, aged ≥80 years, were included in a multistage sample. The participants’ social network diversity was assessed by applying Cohen’s social network index (SNI. The geriatric depression scale and activities of daily living measures were carried out during home visits. Descriptive analyses revealed the distribution of SNI, while the relationship between the SNI and the geriatric depression scale was examined by ordinal logistic regression models controlling possible covariants such as age, sex, and educational attainment. Results: The median age of the sample was 83 years, with females comprising of 54.94% of the sample. The participants’ children, their neighbors, and members of Buddhist temples were reported as the most frequent contacts of the study participants. Among the 435 participants, 25% were at risk of social isolation due to having a “limited” social network group (SNI 0–3, whereas 37% had a “medium” social network

    Regions of Thailand reported sporadic outbreaks of A/H5N1 highly pathogenic avian influenza (HPAI) among poultry between 2004 and 2008. Kamphaeng Phet Province, in north-central Thailand had over 50 HPAI poultry outbreaks in 2004 alone, and 1 confirmed and 2 likely other human HPAI infections between 2004 and 2006. In 2008, we enrolled a cohort of 800 rural Thai adults living in 8 sites within Kamphaeng Phet Province in a prospective study of zoonotic influenza transmission. We studied participants' sera with serologic assays against 16 avian, 2 swine, and 8 human influenza viruses. Among participants (mean age 49.6 years and 58% female) 65% reported lifetime poultry exposure of at least 30 consecutive minutes. Enrollees had elevated antibodies by microneutralization assay against 3 avian viruses: A/Hong Kong/1073/1999(H9N2), A/Thailand/676/2005(H5N1), and A/Thailand/384/2006(H5N1). Bivariate risk factor modeling demonstrated that male gender, lack of an indoor water source, and tobacco use were associated with elevated titers against avian H9N2 virus. Multivariate modeling suggested that increasing age, lack of an indoor water source, and chronic breathing problems were associated with infection with 1 or both HPAI H5N1 strains. Poultry exposure was not associated with positive serologic findings. These data suggest that people in rural central Thailand may have experienced subclinical avian influenza infections as a result of yet unidentified environmental exposures. Lack of an indoor water source may play a role in transmission.

    Full Text Available Abstract Background The recent dramatic decline in dihydroartemisinin-piperaquine (DHA-PPQ efficacy in northwestern Cambodia has raised concerns about the rapid spread of piperaquine resistance just as DHA-PPQ is being introduced as first-line therapy in neighbouring countries. Methods Ex vivo parasite susceptibilities were tracked to determine the rate of progression of DHA, PPQ and mefloquine (MQ resistance from sentinel sites on the Thai–Cambodian and Thai–Myanmar borders from 2010 to 2015. Immediate ex vivo (IEV histidine-rich protein 2 (HRP-2 assays were used on fresh patient Plasmodium falciparum isolates to determine drug susceptibility profiles. Results IEV HRP-2 assays detected the precipitous emergence of PPQ resistance in Cambodia beginning in 2013 when 40 % of isolates had an IC90 greater than the upper limit of prior years, and this rate doubled to 80 % by 2015. In contrast, Thai–Myanmar isolates from 2013 to 14 remained PPQ-sensitive, while northeastern Thai isolates appeared to have an intermediate resistance profile. The opposite trend was observed for MQ where Cambodian isolates appeared to have a modest increase in overall sensitivity during the same period, with IC50 declining to median levels comparable to those found in Thailand. A significant association between increased PPQ IC50 and IC90 among Cambodian isolates with DHA-PPQ treatment failure was observed. Nearly all Cambodian and Thai isolates were deemed artemisinin resistant with a >1 % survival rate for DHA in the ring-stage assay (RSA, though there was no correlation among isolates to indicate cross-resistance between PPQ and artemisinins. Conclusions Clinical DHA-PPQ failures appear to be associated with declines in the long-acting partner drug PPQ, though sensitivity appears to remain largely intact for now in western Thailand. Rapid progression of PPQ resistance associated with DHA-PPQ treatment failures in northern Cambodia limits drugs of choice in

    Communities of bacterial endophytes within the rice landraces cultivated in the highlands of northern Thailand were studied using fingerprinting data of 16S rRNA and nifH genes profiling by polymerase chain reaction-denaturing gradient gel electrophoresis. The bacterial communities' richness, diversity index, evenness, and stability were varied depending on the plant tissues, stages of growth, and rice cultivars. These indices for the endophytic diazotrophic bacteria within the landrace rice Bue Wah Bo were significantly the lowest. The endophytic bacteria revealed greater diversity by cluster analysis with seven clusters compared to the endophytic diazotrophic bacteria (three clusters). Principal component analysis suggested that the endophytic bacteria showed that the community structures across the rice landraces had a higher stability than those of the endophytic diazotrophic bacteria. Uncultured bacteria were found dominantly in both bacterial communities, while higher generic varieties were observed in the endophytic diazotrophic bacterial community. These differences in bacterial communities might be influenced either by genetic variation in the rice landraces or the rice cultivation system, where the nitrogen input affects the endophytic diazotrophic bacterial community.

    The public knowledge of diabetes is important for prevention of disease. This study aimed to evaluate knowledge of diabetes, risk factors, and the common warning signs of diabetes and complications among community participants in a rural Karen ethnic community. Participants were asked to answer a questionnaire regarding their knowledge of diabetes. Fasting blood glucose testing, blood pressure measurement, and body mass index (BMI) assessment were provided to the participants. The study was conducted at Thasongyang district, Tak province, Thailand. A total of 299 Karen rural residents were included in the study. The median age was 45 years and median fasting blood glucose was 88 mg/dL. The response rate to the questionnaires was 91.97%. Half of the participants knew diabetes is a noncommunicable disease needing lifelong treatment. Overall, one-third of the community participants could correctly answer the knowledge assessment questions regarding risk factors and common features of diabetes. whereas the other two-thirds either gave a wrong answer or were "not sure". Female participants had poorer diabetes knowledge than the males. The public knowledge of diabetes, as represented by this sample of the Karen ethic community, is alarmingly low. There is significant gender difference in knowledge level. Culturally tailored and gender-sensitive diabetes health education interventions are urgently needed in this minority ethnic community.

    A survey of intestinal parasites in dogs was carried out in a rural region around Cantanhede, in northern Portugal, where 301 dog faecal samples were collected from small-ruminant farms. Saturated salt flotation and formol-ether sedimentation techniques were used. An enquiry was conducted in 234 farms and a risk factor evaluation for zoonotic helminths was determined among the 195 farmers who owned dogs. The overall parasite prevalence in faecal samples of dogs was 58.8%, with specific prevalences for Ancylostomidae being 40.9% followed by species of Trichuris (29.9%), Toxocara (8%), Isospora (4%), Capillaria (0.7%) and Spirometra (0.3%). Taeniidae eggs were present in five samples (1.7%) which were analysed with the polymerase chain reaction (PCR) technique and revealed to be from Taenia sp., and not Echinococcus granulosus. This rural region has a traditional small-farm system, in which farm products are mainly for in-house consumption and home slaughtering is a current practice (57%). Analysis showed home slaughtering to be a statistically significant risk factor for the presence of Ancylostomidae (P= 0.007) and Toxocara sp. (P= 0.049). Owning cattle was found to be a significant risk factor for Taenia sp. (P= 0.031).

    Full Text Available Background: Over the past several decades in Northern Thailand, there has been a contest of authoritative knowledge between the Hmong traditional birth system and the Thai biomedical maternity system. In this paper, we explore the contest in one Hmong village by describing the traditional and biomedical practices; families’ birth location choices; and elements of authoritative knowledge. Methods: We built on a village survey and conducted an ethnographic qualitative case study of 16 families who made different pregnancy care choices. Results: The contest is being won by the Thai biomedical system, as most families deliver at the hospital. These families choose hospital births when they evaluate problems or potential problems; they have more confidence in the superior Thai biomedical system with its technology and medicines than in the inadequate Hmong traditional system. But the contest is ongoing, as some families prefer to birth at home. These families choose home births when they want a supportive home environment; they embrace traditional Hmong birth knowledge and practices as superior and reject hospital birth practices as unnecessary, harmful, abusive, and inadequate. Despite their choice for any given pregnancy, the case study families feel the pull of the other choice: hospital birth families lament loss of the home environment and express their dislike of hospital practices; and home birth families feel the anxiety of potentially needing quick obstetrical assistance that is far away. Conclusion: While most families choose to participate in the Thai biomedical system, they also use Hmong pregnancy and postpartum practices, and some families choose home births. In this village, the contest for the supremacy of authoritative birth knowledge is ongoing.

  4. Messages of distinction: the HIV/AIDS media campaign in Thailand.

    In predominantly rural Thailand, television is a primary source of HIV/AIDS knowledge. Since 1990, HIV/AIDS warning messages have been aired regularly and repeatedly on television as part of the national strategy to minimize transmission of HIV. The education and prevention messages chosen do more than suggest measures to avoid infection. Within a logic of risk, these messages also define characteristics of people who are signified as threatening agents of infection. In Thailand, prostitutes and drug users are portrayed as the feared Other. Because commercial sex is so widespread, the demarcation of prostitutes as a high risk group signals a diffuse threat not easily subject to conceptual distancing. It is the pervasive and often fear-based associations born of the media material that, in large part, establish the basis for emergent practice when thoughts or actions are triggered by consideration of HIV/AIDS.

    Provision of adequate numbers of quality fish fry is often a key constraint on aquaculture development. The management of climate-related risks in hatchery and nursery management operations has not received much attention, but is likely to be a key element of successful adaptation to climate change in the aquaculture sector. This study explored the sensitivities and vulnerability of freshwater fish fry production in 15 government hatcheries across Northern Thailand to climate variability and evaluated the robustness of the proposed adaptation measures. This study found that hatcheries have to consider several factors when planning production, including: taking into account farmer demand; production capacity of the hatchery; availability of water resources; local climate and other area factors; and, individual species requirements. Nile tilapia is the most commonly cultured species of freshwater fish. Most fry production is done in the wet season, as cold spells and drought conditions disrupt hatchery production and reduce fish farm demand in the dry season. In the wet season, some hatcheries are impacted by floods. Using a set of scenarios to capture major uncertainties and variability in climate, this study suggests a couple of strategies that should help make hatchery operations more climate change resilient, in particular: improving hatchery operations and management to deal better with risks under current climate variability; improving monitoring and information systems so that emerging climate-related risks are known sooner and understood better; and, research and development on alternative species, breeding programs, improving water management and other features of hatchery operations.

    A cross sectional study was conducted between January, 2001 and June, 2002 to determine the life-style factors associated with malaria infection among hilltribes in the Chiang Rai Province, Mae Fah Luang district located along the Thai-Myanmar border, northern Thailand. The data collected were a thick blood film examination and a face-to-face interview using a local language interviewer at a mobile clinic or a home visit. The chi-square test, odds ratio, 95% confidence interval and multiple logistic regression were used as data analysis. P. vivax (61.3%) was detected more than P falciparum (38.2%). Parasitic infection was seen in 45.8% of a total of 417 blood examinations. The study area was in a valley covered with forests and small streams, which was ideal for a malaria epidemic. The communities were distributed along different ethnic groups. There were 12 ethnic groups, dominated by the Muser, Eko, and Akha tribes (60-70%). The risk factors included living or working in the forest, accompanying their family during movement through the forest, age < or =14 years (40.9%), poor knowledge of how to protect against malaria (75-80%), and unavailability of protection against malaria via long sleeved clothes, topical repellents, and insecticide treated nets (use and carry), which resulted in an increased exposure to malaria and risk for malaria infection.

    The purpose of this study was to examine the impact of parenting styles on emotional intelligence of HIV-affected children in Thailand. This study uses data from 205 HIV-affected children in northern and northeastern Thailand. Correlation and regression analyses were used to examine the predictors of emotional intelligence. Children reporting higher levels of stress reported less caring parenting style (standardized beta [B]=-0.18, p=0.050). Children with higher self-esteem were also more likely to perceive their parents as caring (B=0.48, p=0.002). Children who scored lower on their self-esteem reported their parents to be more overprotective (B=-0.30, p=0.030), and children reporting higher levels of stress reported their parents to be more overprotective (B=0.12, p=0.010). Children reporting caring parenting style were significantly more likely to report higher emotional intelligence (B=0.66, p=0.001). Parenting styles play an important role in the emotional intelligence. Identifying and testing interventions to help parents improve their parenting styles, while helping their HIV-affected children cope with stress and self-esteem, are essential in promoting mental health of HIV-affected children in Thailand.

    To investigate the potential cancer risk resulting from biomass burning, polycyclic aromatic hydrocarbons (PAHs) bound to fine particles (PM2.5) were assessed in nine administrative northern provinces (NNP) of Thailand, before (N-I) and after (N-II) a haze episode. The average values of Σ 3,4-ring PAHs and B[a] P Equivalent concentrations in world urban cities were significantly (p<0.05) much higher than those in samples collected from northern provinces during both sampling periods. Application of diagnostic binary ratios of PAHs underlined the predominant contribution of vehicular exhaust to PM2.5-bound PAH levels in NNP areas, even in the middle of the agricultural waste burning period. The proximity of N-I and N-II values in three-dimensional (3D) principal component analysis (PCA) plots also supports this conclusion. Although the excess cancer risk in NNP areas is much lower than those of other urban area and industrialized cities, there are nevertheless some concerns relating to adverse health impacts on preschool children due to non-dietary exposure to PAHs in home environments.

    Personal inhalation exposure samples were collected and analyzed for polycyclic aromatic hydrocarbons (PAHs) for 126 selected volunteers during heating and non-heating seasons in a typical northern Chinese city, Taiyuan. Measured personal PAH exposure levels for the urban residents in the heating and non-heating seasons were 690 (540-1051) and 404 (266-544) ng/m(3) , respectively, while, for the rural residents, they were 770 (504-1071) and 312 (201-412) ng/m(3) , respectively. Thus, rural residents are exposed to lower PAH contamination in comparison with the urban residents in the non-heating seasons. In the heating season, personal PAH inhalation exposure levels were comparable between the urban and rural residents, in part owing to the large rate of residential solid fuel consumption in the rural area for household cooking and heating. The estimated incremental lifetime cancer risks (ILCR) due to PAH exposure in Taiyuan were 3.36 × 10(-5) and 2.39 × 10(-5) for the rural and urban residents, respectively, significantly higher than the literature-reported national average level, suggesting an urgent need of PAH pollution control to protect human health. © 2014 John Wiley & Sons A/S.

    Since the mid-1990s, Thailand has been one of the largest per capita consumers of methamphetamine pills (ya ba - "crazy drug") in the world and one of the leading consumers of methamphetamine in Southeast Asia, with its youth comprising the majority of users. This article examines the socio-cultural context of methamphetamine use among young Thai in order to understand its widespread appeal. The study is based on 18 months of ethnographic research in Chiang Mai, northern Thailand, between 2002 and 2006 and a follow-up field trip in 2011. In-depth interviews were carried out with 211 young people aged between 15 and 25 in institutional and non-institutional settings. Many of the findings derive from participant observation and informal interviews with a small sample of 20 people. Chiang Mai youth have transformed methamphetamine from a labourers' drug centred on economic utility to a multi-purpose youth drug primarily consumed for pleasure and performance. Ya ba appeals to many young Thai due to its positive image as a modern and fashionable consumer commodity, with confidence in these synthetic pills drawing on and mirroring a broader faith in modern (western) medicine. The growing demand for ya ba in northern Thailand is in part a reflection of the changing social values that have accompanied rapid urbanisation and modernisation in Thailand. In their overwhelming aspiration to be modern, young Thai are consuming ya ba not to rebel against the dominant culture, but to keep up with the demands and expectations of a modern capitalist society.

    This study sheds light on obstacles to safe sexual health for young Thais and their need for appropriate sexual and reproductive health services. The study population was 1,745 unmarried adolescents aged 17-20 who resided or worked in Chiang Mai, the major city in northern Thailand. The study used quantitative and qualitative methods to explore the vulnerability of sexually active adolescents as well as the lack of support and care for them from parents and health providers. We found that young Thais still prefer pharmacies for self-medication and use government health care facilities as a last resort. Current health services are not suitable for young people in northern Thailand because they lack privacy and impose judgemental attitudes, especially towards sexually active adolescent females. Current programs for adolescent sexual and reproductive health focus on education and counselling and do not provide appropriate privacy or clinical care. There is a pressing need for advocacy, policy support for the development of youth-friendly sexual and reproductive health services in Thailand. PMID:23082599

    To assess the effect of different levels of exposure to the Northern Ontario School of Medicine's (NOSM's) distributed medical education programs in northern Ontario on FPs' practice locations. Cross-sectional design using longitudinal survey and administrative data. Canada. All 131 Canadian medical graduates who completed FP training in 2011 to 2013 and who completed their undergraduate (UG) medical degree or postgraduate (PG) residency training or both at NOSM. Exposure to NOSM's medical education program at the UG (n = 49) or PG (n = 31) level or both (n = 51). Primary practice location in September of 2014. Approximately 16% (21 of 129) of FPs were practising in rural northern Ontario, 45% (58 of 129) in urban northern Ontario, and 5% (7 of 129) in rural southern Ontario. Logistic regression found that more rural Canadian background years predicted rural practice in northern Ontario or Ontario, with odds ratios of 1.16 and 1.12, respectively. Northern Canadian background, sex, marital status, and having children did not predict practice location. Completing both UG and PG training at NOSM predicted practising in rural and northern Ontario locations with odds ratios of 4.06 to 48.62. Approximately 61% (79 of 129) of Canadian medical graduate FPs who complete at least some of their training at NOSM practise in northern Ontario. Slightly more than a quarter (21 of 79) of these FPs practise in rural northern Ontario. The FPs with more years of rural background or those with greater exposure to NOSM's medical education programs had higher odds of practising in rural northern Ontario. This study shows that NOSM is on the road to reaching one of its social accountability milestones.

  14. The Politics of PVC: Technology and Institutions in Upland Water Management in Northern Thailand

    Directory of Open Access Journals (Sweden)

    Full Text Available Conflict over water has grown in the mountainous areas of Thailand since the replacement of opium with alternative crops. PVC-sprinkler irrigation has enabled dry-season expansion of these cash crops on sloping lands, intensifying demand for water when it is most scarce. The technology and institutions that form the backbone of these irrigation systems have evolved simultaneously in a process of adaptive governance, in which local farmers draw on local social resources to balance competition and cooperation. Common conceptions of upstream – downstream conflict, pitting Thai against ethnic minorities in a struggle for resources, dominate the discourse of watersheds in Thailand. Upland water users themselves are diverse and their resource management systems are dynamic, even if they are not recognised as legitimate users of water. Understanding how upland communities create local systems of resource governance through dry-season irrigation is highly relevant for governance at higher levels, such as in the efforts to establish watershed networks and river basin organisations.

    Full Text Available Abstract Background Diarrhea is a major public health problem in Thailand. The Ministry of Public Health, Thailand, has been trying to monitor and control this disease for many years. The methodology and the results from this study could be useful for public health officers to develop a system to monitor and prevent diarrhea outbreaks. Methods The objective of this study was to analyse the epidemic outbreak patterns of diarrhea in Chiang Mai province, Northern Thailand, in terms of their geographical distributions and hotspot identification. The data of patients with diarrhea at village level and the 2001–2006 population censuses were collected to achieve the objective. Spatial analysis, using geographic information systems (GIS and other methods, was used to uncover the hidden phenomena from the data. In the data analysis section, spatial statistics such as quadrant analysis (QA, nearest neighbour analysis (NNA, and spatial autocorrelation analysis (SAA, were used to identify the spatial patterns of diarrhea in Chiang Mai province. In addition, local indicators of spatial association (LISA and kernel density (KD estimation were used to detect diarrhea hotspots using data at village level. Results The hotspot maps produced by the LISA and KD techniques showed spatial trend patterns of diarrhea diffusion. Villages in the middle and northern regions revealed higher incidences. Also, the spatial patterns of diarrhea during the years 2001 and 2006 were found to represent spatially clustered patterns, both at global and local scales. Conclusion Spatial analysis methods in GIS revealed the spatial patterns and hotspots of diarrhea in Chiang Mai province from the year 2001 to 2006. To implement specific and geographically appropriate public health risk-reduction programs, the use of such spatial analysis tools may become an integral component in the epidemiologic description, analysis, and risk assessment of diarrhea.

    Background Data on the burden of the 2009 influenza pandemic in Asia are limited. Influenza A(H1N1)pdm09 was first reported in Thailand in May 2009. We assessed incidence and epidemiology of influenza-associated hospitalizations during 2009–2010. Methods We conducted active, population-based surveillance for hospitalized cases of acute lower respiratory infection (ALRI) in all 20 hospitals in two rural provinces. ALRI patients were sampled 1∶2 for participation in an etiology study in which nasopharyngeal swabs were collected for influenza virus testing by PCR. Results Of 7,207 patients tested, 902 (12.5%) were influenza-positive, including 190 (7.8%) of 2,436 children aged incidence of hospitalized influenza cases was 136 per 100,000, highest in ages 75 years (407 per 100,000). The incidence of influenza A(H1N1)pdm09 was 62 per 100,000 (214 per 100,000 in children <5 years). Eleven influenza-infected patients required mechanical ventilation, and four patients died, all adults with influenza A(H1N1)pdm09 (1) or H3N2 (3). Conclusions Influenza-associated hospitalization rates in Thailand during 2009–10 were substantial and exceeded rates described in western countries. Influenza A(H1N1)pdm09 predominated, but H3N2 also caused notable morbidity. Expanded influenza vaccination coverage could have considerable public health impact, especially in young children.

    Millennium Development Goal 1 encourages local initiatives for the eradication of extreme poverty. However, monitoring is indispensable to insure that actions performed at higher policy levels attain success. Poverty in rural areas in low- and middle-income countries remains chronic. Nevertheless, a rural area (Cuatro Santos) in northern Nicaragua has made substantial progress toward poverty eradication by 2015. We examined the level of poverty there and described interventions aimed at reducing it. Household data collected from a Health and Demographic Surveillance System was used to analyze poverty and the transition out of it, as well as background information on family members. In the follow-up, information about specific interventions (i.e., installation of piped drinking water, latrines, access to microcredit, home gardening, and technical education) linked them to the demographic data. A propensity score was used to measure the association between the interventions and the resulting transition from poverty. Between 2004 and 2009, poverty was reduced as a number of interventions increased. Although microcredit was inequitably distributed across the population, combined with home gardening and technical training, it resulted in significant poverty reduction in this rural area. Sustainable interventions reduced poverty in the rural areas studied by about one-third.

    Since the Asian financial crisis in 1997, Thailand has become highly dependent on exports as the main engine of economic growth. In 2008, the ratio of export to GDP was about 76.5 percent. The global economic crisis triggered by the sub-prime loans debacle in the United States has prompted Thailand to rethink its high dependence on export. This paper examines the options for external and internal economic rebalancing strategies for Thailand. External rebalancing will require Thailand to rely ...

    A PV grid connected system with small battery bank has been set up in a rural district, North Thailand in order to demonstrate a 2-mode operation concept. The objective is to gain experience on the PV grid connected concept without battery storage. However, due to the evening peak demand and a rather weak distribution grid which is typical in rural areas, small battery bank is still required to enable the maximum energy transfer to grid for the time being before moving fully to the no battery mode. The analyzed data seems to indicate possible performance improvement by re-arranging the number of PV modules and battery in the string.

  1. Worlds apart 2: Thailand and the Philippines. Heroes and villains in an Asian population drama.

    1994-01-01

    A comparison of population growth was made for the Philippines and Thailand. Although both countries had 20 million population in 1950 and developed family planning (FP) in similar stages, Thailand had a contraceptive use rate of about 65% and total fertility of 2.1 and a population of 57 million, while the Philippines had 7.4 million more people and slower economic development. Environmental effects of this situation in the Philippines included the movement of people to marginal mountainous land and soil erosion and degradation. A major medical problem has been complications from illegal abortion. While Thailand is expected to reach replacement level by 1995, the Philippines will not reach replacement level until at least 2015, by which time the population will be 20 million more than in Thailand. Thailand is experiencing declines in school age population, and the Philippines is experiencing growth in its school enrollment and labor force. Although the Philippines has received more foreign FP assistance than Thailand, the demographic impact has been greater in Thailand. The Philippines made mistakes in centralizing its FP efforts in Manila and spending too much on communication programs and less on service delivery in rural areas. After 1978, the emphasis shifted and funds were diminished for all social services by the Marcos regime. Mrs. Aguino could not right the wrongs of the previous administration because of her strong commitment to Roman Catholicism. The new Fidel Ramos administration and Health Secretary Flavier are now dedicated to promotion of primary health care and FP. Unfortunately, past political and religious leaders abnegated their responsibility in promoting responsible parenthood and providing appropriate social services. Instead these parties achieved personal wealth at the expense of the masses and protected a "dubious morality."

    The demographic and socio-economic determinants of post-neonatal deaths (n = 475) in a special project area of rural northern India (Ballabgarh) were ascertained from 1991 to 1999 using the electronic database system of the project area for data extraction, and were compared with the eligible living children of the same age using a matched population-based case-control study design. Similar determinants were also ascertained in neonatal deaths (n = 212) using the same study design. After controlling for the potential confounders using conditional logistic regression analyses, lower caste (a proxy measure for low socio-economic conditions in rural India) was found to be significantly associated with higher post-neonatal deaths (OR = 2.21). Higher maternal age (>30 years) and fathers' lower educational levels were significantly associated with higher neonatal deaths, in addition to higher post-neonatal deaths in the same area.

    Thailand is a non-nuclear weapon state. The non-nuclear activities are mainly medical, agricultural, and industrial. Therefore, Thailand ratified the Nuclear Non-Proliferation Treaty (NPT) since 1972 and has been entry into force of the Comprehensive Safeguards Agreement (INFCIRC 241) since 1974. Based on the INFCIRC 153, Thailand established a system of accounting for and control of all nuclear material subject to safeguards under the Agreement. In order to ensure the peaceful use of nuclear in Thailand the Nuclear-Non- Proliferation Center of Office of Atoms for Peace (NPC, OAP) was established to act as State level Safeguards. NPC is responsible for keeping records and providing information under requirement of Comprehensive Safeguards Agreement. In addition, the strengthening of cooperation and good coordination between Thailand and IAEA are indeed important and necessary to implementation safeguards in country. Based on the report of IAEA safeguards statement, there is no indication of the diversion of nuclear materials or misuse of the facility or the items in Thailand. Up to present, nuclear activities in Thailand are peaceful without diversion of using. This paper reviews the current status of the implementation Safeguards in Thailand. (author)

    The Seven South East Asian Studies (7-SEAS) is a grass-root program and seeks to perform interdisciplinary research in the field of aerosol-meteorology and climate interaction in the Southeast Asian region, particularly for the impact of biomass burning on cloud, atmospheric radiation, hydrological cycle, and regional climate. Participating countries include Indonesia, Malaysia, Philippines, Singapore, Thailand, Taiwan, Vietnam, and USA. A series of field experiments have been conducted during springtime biomass burning seasons in northern Southeast Asia, i.e., Dongsha Experiment in 2010, Son La Campaigns in 2011 and 2012, and BASELInE (Biomass-burning Aerosols & Stratocumulus Environment: Lifecycles and Interactions Experiment) in 2013, respectively. Given an example, during 2010 Dongsha Experiment, a monitoring network for ground-based measurements was established, including five stations from northern Thailand and central Vietnam to Taiwan, with a supersite at the Dongsha Island (i.e. Pratas Island) in South China Sea (or East Sea). Aerosol chemistry sampling was performed for each station for characterizing the compositions of PM2.5/PM10 (some for TSP) including water-soluble ions, metal elements, BC/OC, Hg and dioxins. This experiment provides a relatively complete and first dataset of aerosol chemistry and physical observations conducted in the source/sink region for below marine boundary layer and lower free troposphere of biomass burning/air pollutants in the northern SE Asia. This presentation will give an overview of these 7-SEAS activities and their results, particularly for the characterization of biomass-burning aerosol at source regions in northern Thailand and northern Vietnam, and receptor stations in Taiwan, which is rarely studied.

    Full Text Available Objective: To identify factors associated with HIV and hepatitis B virus (HBV co-infection in Northern Thailand. Methods: We tested 355 newly diagnosed HIV-infected subjects for hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B core antibody by using immunochromatographic and ELISA methods. Cases were positive for one or more of the HBV markers and controls were negative for all HBV markers. All study subjects were asked to complete a questionnaire to identify the associations between variables. We used logistic regression model to evaluate the associations between demographic and behavioral variables and HIV/HBV co-infection. Results: A total of 41 cases and 83 controls were suitable to analyze in the study. Among them, 15.0% were males, 40.3% were 30–39 years old, 62.9% were married, 18.6% were illiterate and 89.5% were employed. Besides, 26 cases (23.4% had a history of a blood transfusion, 12.9% had a history of jaundice, 29.0% had a CD4 cell count ≤ 200 cells/mm3, 0.8% were intravenous drug user, 29.8% tattooed, 64.5% had a body piercing, 12.1% were commercial sex workers, 11.3% had first sexual intercourse at age ≤ 15 years old, 6.5% were homosexual, and no one had a history of HBV vaccination. After controlling for all possible confounder factors in the multiple logistic regression model, we found two factors associated with HIV/ HBV co-infection: number of years in school and CD4 cell count. Subjects with no education were more likely to have HIV/HBV co-infection, which was 7.07 times (odds ratio = 7.07, 95% confidence interval = 1.77–28.24 greater than those with 7 years of education group. Subjects with CD4 count ≤ 200 cells/mm3 were less likely to have HIV/HBV co-infection than those with a CD count ≥ 200 cells/mm3 (odds ratio = 0.35, 95% confidence interval = 0.13–0.94. Conclusions: Our findings suggest that having a good education and having a good immune status are a protective factor of HIV

    Few data are available on the prevalence of cognitive impairment no dementia (CIND) in rural China. The aim of this study was to estimate the prevalence of CIND in individuals aged 60 years and older in a large rural community, and to analyze the associated risk factors. A two-phase, door-to-door epidemiological study was used for residents aged 60 years and older in Ji County, a rural county near Tianjin in Northern China. In phase 1 of the study, the Mini-Mental State Examination and Clinical Dementia Rating were administered for screening purposes. In phase 2, the subjects who screened positive were further examined by neurologists. A total of 5,744 individuals underwent the home visit interview, where demographic variables and comorbidities were recorded; 5,550 individuals completed the two phases. CIND was diagnosed by the Aging, Demographics and Memory Study on CIND criteria. The odds ratio (OR) for each risk factor was calculated by logistic regression analysis. The prevalence of CIND among those aged 60 years and older was 23.3%. The prevalence of CIND was lower among those with a higher level of education or social involvement. CIND was more prevalent in females, older individuals, those with a past history of stroke, and those living without a partner. Significant risk factors were found by multivariate analyses: past history of stroke (OR = 1.889; 95% CI: 1.437-2.483); being female (OR = 1.546; 95% CI: 1.305-1.832); and having no partner (divorced, widowed or single; OR = 1.250; 95% CI: 1.042-1.499). In turn, level of education (OR = 0.560; 95% CI: 0.460-0.681) and engagement in social activities (OR = 0.339; 95% CI: 0.258-0.404) were protective factors. This is the first large-scale community-based epidemiological study assessing the prevalence of cognitive loss in the rural Chinese population. The total prevalence of CIND observed was 23.3%, which was higher than in other studies in Western and Asian countries. Living without a partner, female gender

    Full Text Available This paper reports capability of a newly-proposed index called the aerosol prediction index (API in the determination and mapping of near-ground PM10 concentrations (at spatial resolution of 500 x 500 m during the 2009 and 2010 burning seasons in upper northern Thailand. API is a normalized index defined based on the difference in the observed reflectance data at two spectral bands of the MODIS instrument aboard NASA�s Terra satellite; Band 3 (blue and Band 7 (mid-infrared. Initial analysis suggested that API had strong correlation with the corresponding MODIS-AOD and AERONET-AOD with coefficient of determination (R2 about 0.62 in both cases, and also with the reference PM10 data with R2 of 0.66. In terms of predictive performance, it exhibited low bias at low PM10 condition and achieved impressive prediction accuracy with relative error of 10.78 %. The near-ground PM10 concentration map yielded from the proposed index was proved very useful in the comprehensive assessment of aerosol pollution situation over entire area at fine spatial detail. This task could not be fulfilled from sole use of the ground-based measured data or standard MODIS-AOD product. These findings indicate that API should be a promising tool for the regular monitoring of air pollution severity over the concerned area.

    Full Text Available Similar to other parts of the world, the prevalence of type 2 diabetes mellitus (T2DM in the Asia-Pacific Region has rapidly increased during the last few decades. The purposes of this pilot study were to determine the feasibility and the effects of a capacity building program for Village Health Volunteers (VHVs to support self-management in a T2DM high risk population from a rural subdistrict in Northeast Thailand. Both quantitative and qualitative data were collected using surveys, focus group discussions, and in-depth interviews. Data were analyzed and used to develop a 12-week capacity building program for VHVs. This program was then implemented on 60 subjects at high risk of T2DM in the selected community. According to the paired t-test and Wilcoxon-signed rank test, VHVs had higher scores on knowledge and self-efficacy of T2DM prevention after a 12 week intervention (p = .03 and p = .02, respectively. Study participants at risk for T2DM also had a significant increase in T2DM knowledge and self-management (p < .001. Implementation of the capacity building program for VHVs in Northeast Thailand was feasible. The key successes were strong community bonding, community empowerment, and support from family and public health nurses. Effects of the program should be examined with those in other Asia-Pacific countries.

    reported for sub-Saharan Africa, young people are increasingly turning their backs on agriculture, seeing it as an occupation that is back-breaking and only fit for old people (FAO, 2014). The aim of this chapter is to explore the livelihood strategies and aspirations of young people living in a rural area...... how, contrary to the trend in much of sub-Saharan Africa, many young people are choosing to stay in their rural villages and engage in farming. This is partly due to the availability of land and government programmes that have been introduced to stimulate agriculture. Increasingly, however, young...... people are not relying solely on farming, but are also engaging in nonfarm activities. Some young people are shown to be highly entrepreneurial, managing to set up and run businesses despite facing constant and changing challenges. Whether they are based in the village or in the nearby small town, most...

    Alluvial diamonds with no obvious sources ('headless placers') are found in several areas of SE Asia and Oceania, including Myanmar, southern Thailand (Phuket), Sumatra, Kalimantan and eastern Australia. These deposits occur in relatively young geological terrains, in contrast to the Archaean or Proterozoic terrains that host most primary diamond deposits and their associated alluvial workings. Significant quantities of diamonds have been recovered from two areas in Myanmar, Momeik in the northern part of the country, and Theindaw in the southern part, and from the Phuket-Takuapa area of SW Thailand. Smaller quantities have been found in several other localities, notably in the Taungoo-Htantabin area of Myanmar. The Momeik diamonds are recovered during mining of gemstone gravels; the Theindaw and Phuket diamonds are by-products of tin dredging. To understand the origin of these enigmatic diamonds and to provide an improved exploration model, we are carrying out detailed studies of the morphology, mineral inclusions, internal growth structures and growth history, nitrogen concentration and aggregation state, and carbon isotopic composition of diamonds from Myanmar, Thailand and eastern Australia. We have examined >40 stones from Phuket, >110 from Theindaw and >25 from Momeik; these range in size from <0.1 ct to 3.5 ct, averaging ca 0.2 ct. While there are differences among the samples from different areas, the small sample size means these may not be representative and the similarities among the samples are striking. They are therefore described together here. More detailed data are given by Win et al., (1998) and Wathanakul et al., (1998)

    The "rural pipeline" suggests that students educated in rural, or other underserviced areas, are more likely to establish practices in such locations. It is upon this concept that the Northern Ontario School of Medicine (NOSM) was founded. Our analysis answers the following question: Are physicians who were educated at NOSM more likely to practice in rural and northern Ontario compared with physicians who were educated at other Canadian medical schools? We used data from the College of Physicians and Surgeons of Ontario. We compared practice locations of certified Ontario family physicians who had graduated from NOSM vs. other Canadian medical schools in 2009 or later. We categorized the physicians according to where they completed their undergraduate (UG) and postgraduate (PG) training, either at NOSM or elsewhere. We used logistic regression models to determine if the location of UG and PG training was associated with rural or northern Ontario practice location. Of the 535 physicians examined, 67 had completed UG and/or PG medical education at NOSM. Over two thirds of physicians with any NOSM education were practicing in northern areas and 25.4% were practicing in rural areas of Ontario compared with those having no NOSM education, with 4.3 and 10.3% in northern and rural areas, respectively. Physicians who graduated from NOSM-UG were more likely to have practices located in rural Ontario (OR = 2.57; p = 0.014) whereas NOSM-PG physicians were more likely to have practices in northern Ontario (OR = 57.88; p education was associated with an increased likelihood of practicing in rural (NOSM-UG) and northern (NOSM-PG) Ontario.

    To investigate the current status of epilepsy treatment and the efficacy and adverse effects of phenobarbital therapy in rural areas of Northern China. A total of 2192 patients diagnosed with convulsive epilepsy were recruited from seven different rural regions in Jilin Province, China to investigate the current status of epilepsy treatment, and 1379 of them were enrolled in a standard phenobarbital therapy trial. Patients were selected according to strict inclusion and exclusion criteria, and medical records for all patients were collected and analyzed before the standard treatment was started. Patients were followed up monthly, and efficacy in 1218 patients was analyzed at 1, 3, 6 and 12 months of treatment. More patients had the initial seizure in juveniles than in adults, and 40.72% of the 2192 patients were not receiving any treatment before the treatment trial. The efficacy of phenobarbital increased and adverse effects decreased within the treatment period. Among the 349 patients who were followed up for 12 months from the beginning of the phenobarbital treatment, seizures were decreased by more than 75% in 71.3% of patients using a low-to-medium dose of phenobarbital. Major adverse effects of phenobarbital included mild exhaustion, drowsiness, dizziness and headache. Standardized long-term and regular administration of phenobarbital at a low-to-medium dose can be used as an effective, economic and safe treatment against epilepsy in rural areas.

    Greenhouse gas (GHG) emission is one of the serious international environmental issues that can lead to severe damages such as climate change, sea level rise, emerging disease and many other impacts. Rice cultivation is associated with emissions of potent GHGs such as methane and nitrous oxide. Thai rice has been massively exported worldwide however the markets are becoming more competitive than ever since the green market has been hugely promoted. In order to maintain the same level or enhance of competitiveness, Thai rice needs to be considered for environmentally conscious products to meet the international environmental standards. Therefore, it is necessary to evaluate the greenhouse gas emissions throughout the life cycle of rice production in order to identify the major emission sources and possible reduction strategies. In this research, the rice variety considered is Khao Dawk Mali 105 (KDML 105) cultivated by organic practices. The data sources were Don-Chiang Organic Agricultural Cooperative (DCOAC), Mae-teang district, Chiang Mai province, Thailand and the Office of Agricultural Economics (OAE) of Thailand with onsite records and interviews of farmers in 2013. The GHG emissions were calculated from cradle-to-farm by using the Life Cycle Assessment (LCA) approach and the 2006 IPCC Guideline for National Greenhouse Gas Inventories. The functional unit is defined as 1 kg of paddy rice at farm gate. Results showed that the total GHG emissions of organic rice production were 0.58 kg CO 2 -eq per kg of paddy rice. The major source of GHG emission was from the field emissions accounting for 0.48 kg CO 2 -eq per kg of paddy rice, about 83% of total, followed by land preparation, harvesting and other stages (planting, cultivation and transport of raw materials) were 9, 5 and 3% of total, respectively. The comparative results clearly showed that the GHG emissions of organic paddy rice were considerably lower than conventional rice production due to the

    Full Text Available The purpose of the study was twofold: 1 To study the background of cross-cultural marriage in Isan, Thailand; 2 To study cross-cultural marriage rituals of Isan women, Thailand. The study was carried out from February 2012 to February 2014 and was conducted in Khon Kaen, Udon Thani, and Nong Khai provinces. The research sample was composed of 80 individuals. The data collection tools were survey, interviews, observations and focus-group discussions. Results found that the main reason for Isan women marrying foreign men was poverty. They not only wanted to raise family income, but also reciprocate their parents for raising them. As for the foreign men, all had been married before. Some had divorced their former wives, some sons or daughters and some had health problems. Most foreign men were impressed by the good care provided by Isan women, who also had no debt burden. Prior to their marriage with foreign men, most Isan women in the research sample used to work in restaurants in Bangkok, Phuket or other tourist areas. The study found that most weddings followed Isan traditions. The parents, seniors, and relatives participating in the wedding ceremony were seen as witnesses. The bride’s parents received a dowry in cash. Most newly wedded Isan women went to live abroad with their husbands. Their children from previous marriages often went to live with their grandparents. Although many couples have successful marriages, some may experience problems later on. Further study should concern these problems.

    This article assesses the role of local institutions in managing irrigation water use. Fifty irrigation systems in each country were studied in Nepal and Thailand to compare the influence of local institutions on performance of irrigation systems amid changes in external policy and market pressures. Nepal’s new irrigation policy after the re-instatement of multiparty democracy in 1990 emphasized participatory irrigation management transferring the management responsibility from state authorities to water users. The water user associations of traditional farmer-managed irrigation systems were formally recognized by requiring registration with related state authorities. In Thailand also government policies encouraged people’s participation in irrigation management. Today water users are directly involved in management of even some large irrigation systems at the level of tertiary canals. Traditional communal irrigation systems in northern Thailand received support for system infrastructure improvement but have faced increased interference from government. In Thailand market development supported diversification in farming practices resulting in increased areas under high water-demanding commercial crops in the dry season. In contrast, the command areas of most irrigation systems in Nepal include cereal-based subsistence farming with only one-third having commercial farming. Cropping intensities are higher in Nepal than in Thailand reflecting, in part, differences in availability of land and management. In both countries local institutions play an important role in maintaining the performance of irrigation systems as external drivers and local contexts change. Local institutions have provided alternative options for irrigation water use by mediating external pressures.

    Full Text Available Poor and middle-income Thai people rely heavily on primary care health services. These are staffed by a range of professionals. However, it is unknown whether the performance of primary care varies according to the staffing and organization of local service delivery units. Tambon (sub-district health promotion hospitals (THPHs were introduced in 2009 to upgrade the services offered by the previous health centres, but were faced with continuing shortages of doctors and nurses. The Ministry of Public Health (MoPH designated three categories of THPH, defined according to whether they were regularly staffed by a medical practitioner, a qualified nurse or non-clinical public health officers. This study aimed to compare the performance of primary care offered by the three different types of primary care facilities in one public health region of Northern Thailand (Public Health Region 2.A cross-sectional survey was undertaken in 2013. Data were collected on accessibility, continuity, comprehensiveness, co-ordination and community orientation of care from 825 patients attending 23 primary care facilities. These were selected to include the three officially-designated types of Tambon (sub-district health promotion hospitals (THPHs led by medical, nursing or public health personnel. Survey scores were compared in unadjusted and adjusted analyses.THPHs staffed only by public health officers achieved the highest performance score (Mean = 85.14, SD. = 7.30, followed by THPHs staffed by qualified nurses (Mean = 82.86, SD. = 7.06. THPHs staffed by a doctor on rotation returned the lowest scores (Mean = 81.63, SD. = 7.22.Differences in overall scores resulted mainly from differences in reported accessibility, continuity, and comprehensiveness of care, rather than staff skill-mix per se. Policy on quality improvement should therefore focus on improving performance in these areas.

  5. Fire and the production of Astraeus odoratus (Basidiomycetes sporocarps in deciduous dipterocarp-oak forests of northern Thailand

    Full Text Available The genus Astraeus (Diplocystidiaceae forms ectomycorrhizal associations with many tree species and is a common gasteromycete in tropical and temperate ecosystems worldwide. In Thailand, Astraeus is most prevalent in deciduous dipterocarp-oak forest (DOF in the north and north-east and its ecology is uniquely associated with fire. Rural villagers often burn the seasonally dry DOF ground vegetation causing significant environmental disturbance to promote the growth of Astraeus sporocraps—a local culinary delicacy and important source of household income. The purpose of this work is to investigate whether the practice of burning DOF stimulates the production of Astraeus sporocarps in DOF. Burned and unburned Astraeus habitat was surveyed over two years at two sites in Chiang Mai province and one site in Mae Hong Son province. Changes in soil fungi after a fire as well as vascular vegetation growing with Astraeus were studied. All sporocarps collected were identified as Astraeus odoratus. Astraeus sporocarps were found in both burned and unburned areas in 2010. In 2011, an unusually wet year, no sporocarps were found in burned or unburned areas. The top 2 cm of soil experienced high temperatures which killed fungi, but lower depths were well insulated from the heat. A wide range of vascular flora grew in Astraeus habitat, the most common tree species being Dipterocarpus tuberculatus var. tuberculatus and Dipterocarpus obtusifolius var. obtusifolius. This study shows that Astraeus can produce sporocarps without fire and future work can focus on more environmentally benign methods of harvesting this popular mushroom.

    In rural communities of Thailand, traditional healers still play an important role in local health care systems even though modern medicine is easily accessible. Meanwhile, natural forests in Thailand which are important sources of materia medica are being greatly destroyed. This has led to an erosion of traditional Thai medicine. Furthermore, the concept of medicinal plant selection as medicine based on their tastes is still an important component of traditional Thai medicine, but no or little publications have been reported. Thus the aim of the present study is to collect ethnomedicinal data, medicinal plant tastes and relevant information from experienced traditional healers before they are lost. An ethnobotanical survey was carried out to collect information from nine experienced traditional healers on the utilization of medicinal plants in Phatthalung Province, Peninsular Thailand. Data were obtained using semi-structured interviews and participant observations. Plant specimens were also collected and identified according to the plant taxonomic method. A total of 151 medicinal plants were documented and 98 of these are reported in the study. Local names, medicinal uses, parts used, modes of preparation, and the relationship between ailments and tastes of medicinal plant species are presented. This research suggests that traditional healers are still considered important for public health among Thai communities and that many people trust the healing properties of medicinal plants. In the future, it is hoped that traditional Thai medicine will be promoted and therefore will help reduce national public health expense.

    Finding aquaculture development approaches to open up livelihood opportunities for the rural poor and in mainstreaming smallholder fish farmers to reduce poverty remain a challenge. This paper examines the community-based technology transfer mechanism of mudcrab nursery in ponds and its socioeconomic impacts on smallholder mudcrab growers in Northern Samar, Philippines. Results indicated that the technology is a viable enterprise done by a straight culture system method, which is the rearing of crablets from 4.0 cm for 42 days, or by-phases. However, technology adoption hinges on many factors like area ownership, farm distance from household, and market including the type of strategy needed to enhance technology uptake. Collaboration among research and development institutions and local partners is critical in training and empowering rural communities to adopt aquaculture technologies.

    Elderly population is considered as a vulnerable group and prone to develop multiple medical problems. This aging population is rapidly increasing in developing countries especially in Thailand. Methods: This study was a quasi-experimental study to evaluate the effectiveness of Group-Mediated Lifestyle Physical Activity program on change health benefit in physical activity among elderly people by using validated and reliable Global Physical Activity Questionnaire-GPAQv2. The study was conducted in Phranakhonsiayutthaya district, Ayutthaya province due to its population being the second highest elderly in the Central Region of Thailand. A total of 102 persons of age 60 and over who could read and write Thai language were selected purposively. However, 52 elderly were enrolled in the intervention group and 50 were enrolled for the control group. General Linear Model repeated-measures ANOVA was used to evaluate the effects of Group-Mediated Lifestyle Physical Activity (GLPA) program on change health benefit in physical activity among elderly. Results: Overall health benefit at baseline were similar between intervention and control group and found statistically non-significant with p-value 0.638 (>0.05). However, the mean score of health benefit was 23.21 ± 29.23 in intervention group and 20.74 ± 23.18 in control group. One third of participants of intervention group had not found health benefit due to physical activity while in control group this number was more than half. After elderly received Group-Mediated Lifestyle Physical Activity program intervention for 6 month found significant statistical differences as compared with mean score at baseline (health benefit 6 month, intervention group =40.7 ± 34.28 and control group =4.56 ± 8.79). Conclusion: The effect of Group-Mediated Lifestyle Physical Activity program change intervention was statistically significant in health benefit after intervention program between intervention and control group.

    2015-04-01

    Full Text Available Mercury (Hg is a highly toxic pollutant with a long range transport in the atmosphere resulting in both local and global concerns. Understanding of emissions is required to support an effective control strategy. In this study, atmospheric Hg emissions from power sector in Thailand in 2010 were investigated by using the bottom-up approach to improve the accuracy of the estimate by up to 50% in comparison to those provided in global inventories. The activity data of each individual source were collected and emissions factors were assessed based on local sources, well reflecting the emissions behavior of various emitters in Thailand. The atmospheric Hg emissions from power sector in 2010 amounted to 844.5 kg, in which emissions from coal and lignite power plants constituted up to 92.3% and biomass power plants constituted up to 7.4%. Spatial and temporal distribution analysis indicated high emissions in the Central and Northern regions, and from February to July. Annual trends in emissions from 2010 to 2030 were estimated and discussed.

    One devastating landslide event in northern Thailand occurred in 2006 at Ban Nong Pla village, Chiang Klang highland of Nan province after, a massive amount of residual soil moved from upstream to downstream, via creek tributaries, into a main stream after five days of unusual heavy rainfall. In this paper, the geological and engineering properties of residual soil derived fromsedimentary rocks were analyzed and integrated. Geological mapping, electrical resistivity survey and test pits were carried out along three transect lines together with systematic collection of undisturbed and disturbed residual soil samples. As a result, the average moisture content in soil is 24.83% with average specific gravity of 2.68,whereas the liquid limit is 44.93%, plastic limit is 29.35% and plastic index is 15.58%. The cohesion of soil ranges between 0.096- 1.196 ksc and the angle of internal friction is between 11.51 and 35.78 degrees. This suggests that the toughness properties of soil change when moisture content increases. Results from electrical resistivity survey reveal that soil thicknesses above the bedrock along three transects range from 2 to 9 m. The soil shear strength reach the rate of high decreases in the range of 72 to 95.6% for residual soil from shale, siltstone and sandstone, respectively. Strength of soil decreaseswhen the moisture content in soil increases. Shear strength also decreases when the moisture content changes. Therefore, the natural soil slope in the study area will be stable when the moisture content in soil level is equal to one, but when the moisture content between soil particle increases, strength of soil will decrease resulting in soil strength decreasing.

    Weather is suspected to influence fish growth and survival, and be a factor in mass mortality events in cage aquaculture in reservoirs. The purpose of this study was to identify the important climate-related risks faced by cage aquaculture farms; evaluate how these risks were currently being managed; and explore how farmers might adapt to the effects of climate change. Fish farmers were interviewed across the northern region of Thailand to get information on impacts, perceptions and practices. Drought or low water levels, heat waves, cold spells and periods with dense cloud cover, each caused significant financial losses. Perceptions of climate-related risks were consistent with experienced impacts. Risks are primarily managed in the short-term with techniques like aeration and reducing feed. In the mid-term farmers adjust stocking calendars, take financial measures and seek new information. Farmers also emphasize the importance of maintaining good relations with other stakeholders and reservoir management. Larger farms placed greater importance on risk management than small farms, even though types and levels of risk perceived were very similar. Most fish farms were managed by men alone, or men and women working together. Gender differences in risk perception were not detected, but women judged a few risk management practices as more important than men. Fish farmers perceived that climate is changing, but their perceptions were not strongly associated with recently having suffered impacts from extreme weather. The findings of this study provide important inputs to improving risk management under current and future climate.

    The I.U.R.E.P. Orientation Phase Mission assesses the Speculative Uranium Resources in Thailand to be within the range of 1,500 to 38,500 tonnes U. This range is higher than the previous assessment in Phase I because the Mission recognizes additional favourable geological environments. At the same time, the untested and therefore the unknown degree of mineralization in some of these environments is acknowledged. Past exploration, dating from 1977, has been mainly confined to ground surveys of a small mineralized area and to airborne gamma-ray surveys of two small test areas. Ground reconnaissance work and prospecting has recognized some mineralization in several different host rocks and environments. Geological environments considered by the Mission to be favourable for uranium occurrences include sandstone of Jurassic to Triassic age, tertiary sedimentary basins (northern Thailand), tertiary sedimentary basins (southern Thailand), associated with fluorite deposits, granitic rocks, black shales and graphitic slates of the Paleozoic, associated with sedimentary phosphate deposits and associated with monazite sands. It is recommended that exploration for uranium resources in Thailand should continue. Planners of future exploration programmes should take the following activities into consideration. Rapid extension of carborne surveys to cover, without excessive overburdening, all areas having sufficient road density. Airborne gamma-ray surveys should be carried out in certain selected areas. In the selection of such areas, the considerable higher cost factor attendant on this method of surveying dictates that airborne surveys should only be carried out where carborne surveys prove ineffective (lack of adequate road network.) and where the topography is sufficiently even to assure a low but safe clearance and meaningful results. In certain areas, including the Khorat Plateau and the Tertiary Basins in northern and southern Thailand, there is a need for widely spaced

  17. Rural Poverty and Diversification of Farming Systems in Upper Northeast Thailand

    2013-04-01

    Full Text Available In northeast Thailand, 85% of the farmers are smallholders who are unable to meet their basic needs from agricultural production only. These tiny farms survive thanks to non-farm income, which faces increased difficulties as other economic sectors ran out of steam during the recent economic crisis of the late 1990s. In this context, farmers have to rely more on their agricultural production activity and income. But how can this be made possible in a region well-known for its very constraining soil and climatic conditions? To answer this question, and to examine the whole complexity of agricultural development issues, this article proposes an analysis of recent agrarian transformations and an understanding of farmers’ current practices and strategies. A diagnostic analysis of a village agrarian system located in Khon Kaen Province in upper northeast Thailand was carried out in 2002 by using a combination of field observations, interviews with key witnesses of the local history, and a farm survey of 26 diverse households. The recent history illustrates that farmers have shown a high adaptability to rapid changes in their economic environment, such as changing market demand for agricultural products and labour. The differentiation among farming households has led to different types of farmers with different resources, practices, and strategies. Families belonging to the most frequent type have a very tiny holding and their members are permanently or seasonally involved in unskilled off-farm activities. Their low and unstable total cash income is often insufficient to meet the family’s basic needs and they become deeply indebted. As efforts to improve water availability are being made, many Isarn families could improve their living conditions by diversifying their agricultural production systems with more small-scale fruit, vegetable, fish, or livestock production to improve household food security and cash income, eventually combined with non

    Background Dengue is a mosquito-borne infectious disease that constitutes a growing global threat with the habitat expansion of its vectors Aedes aegyti and A. albopictus and increasing urbanization. With no effective treatment and limited success of vector control, dengue vaccines constitute the best control measure for the foreseeable future. With four interacting dengue serotypes, the development of an effective vaccine has been a challenge. Several dengue vaccine candidates are currently being tested in clinical trials. Before the widespread introduction of a new dengue vaccine, one needs to consider how best to use limited supplies of vaccine given the complex dengue transmission dynamics and the immunological interaction among the four dengue serotypes. Methodology/Principal Findings We developed an individual-level (including both humans and mosquitoes), stochastic simulation model for dengue transmission and control in a semi-rural area in Thailand.

    Histoplasmosis is a systemic mycosis caused by inhaling spores of Histoplasma capsulatum, a dimorphic fungus. This fungus grows in soil contaminated with bat and avian excreta. Each year, patients with disseminated histoplasmosis have been diagnosed in Chiang Mai, northern Thailand. No published information is currently available on the environmental sources of this fungus in Chiang Mai or anywhere else in Thailand. The aim of this study was to detect H. capsulatum in soil samples contaminated with bat guano and avian droppings by nested PCR. Two hundred and sixty-five samples were collected from the following three sources: soil contaminated with bat guano, 88 samples; soil contaminated with bird droppings, 86 samples; and soil contaminated with chicken droppings, 91 samples. Genomic DNA was directly extracted from each sample, and H. capsulatum was detected by nested PCR using a primer set specific to a gene encoding 100-kDa-like protein (HcI, HcII and HcIII, HcIV). Histoplasma capsulatum was detected in seven of 88 soil samples contaminated with bat guano, one of 21 soil samples contaminated with pigeon droppings and 10 of 91 soil samples contaminated with chicken droppings. The results indicate the possibility of the association of bat guano and chicken droppings with H. capsulatum in this area of Thailand.

    Full Text Available In this study we report on the protocols adopted and the findings from a pilot study in northern Ghana involving 40 respondents wearing accelerometry devices for a week. We show how integrating energy expenditure data from wearable accelerometry devices with data on activity and time-use can provide a window into agricultural and rural livelihoods in developing country contexts that has not been previously available for empirical research. Our findings confirm some of the stylised facts of agricultural and rural livelihoods, but the study also provides several new insights that come from the triangulation of energy expenditure, time use, and activity data. We report findings and explore the potential applications of using accelerometry devices for a better understanding of agriculture-nutrition linkages in developing countries.

    Full Text Available Differentiation of the fish-borne trematodes belonging to the Opisthorchiidae, Heterophyidae and Lecithodendriidae is important from a clinical and epidemiological perspective, yet it is impossible to do using conventional coprological techniques, as the eggs are morphologically similar. Epidemiological investigation therefore currently relies on morphological examination of adult worms following expulsion chemotherapy. A PCR test capable of amplifying a segment of the internal transcribed spacer region of ribosomal DNA for the opisthorchiid and heterophyid flukes eggs taken directly from faeces was developed and evaluated in a rural community in central Thailand. The lowest quantity of DNA that could be amplified from individual adults of Opisthorchis viverrini, Clonorchis sinensis and Haplorchis taichui was estimated at 0.6 pg, 0.8 pg and 3 pg, respectively. The PCR was capable of detecting mixed infection with the aforementioned species of flukes under experimental conditions. A total of 11.6% of individuals in rural communities in Sanamchaikaet district, central Thailand, were positive for 'Opisthorchis-like' eggs in their faeces using conventional parasitological detection techniques. In comparison to microscopy, the PCR yielded a sensitivity and specificity of 71.0% and 76.7%, respectively. Analysis of the microscopy-positive PCR products revealed 64% and 23% of individuals to be infected with O. viverrini and C. sinensis, respectively. The remaining 13% (three individuals were identified as eggs of Didymozoidae, presumably being passed mechanically in the faeces following the ingestion of infected fishes. An immediate finding of this study is the identification and first report of a C. sinensis-endemic community in central Thailand. This extends the known range of this liver fluke in Southeast Asia. The PCR developed herein provides an important tool for the specific identification of liver and intestinal fluke species for future

    Full Text Available Abstract Background In recent years, interest in the study of inequalities in health has not stopped at quantifying their magnitude; explaining the sources of inequalities has also become of great importance. This paper measures socioeconomic inequalities in self-reported morbidity and self-assessed health in Thailand, and the contributions of different population subgroups to those inequalities. Methods The Health and Welfare Survey 2003 conducted by the Thai National Statistical Office with 37,202 adult respondents is used for the analysis. The health outcomes of interest derive from three self-reported morbidity and two self-assessed health questions. Socioeconomic status is measured by adult-equivalent monthly income per household member. The concentration index (CI of ill health is used as a measure of socioeconomic health inequalities, and is subsequently decomposed into contributing factors. Results The CIs reveal inequality gradients disadvantageous to the poor for both self-reported morbidity and self-assessed health in Thailand. The magnitudes of these inequalities were higher for the self-assessed health outcomes than for the self-reported morbidity outcomes. Age and sex played significant roles in accounting for the inequality in reported chronic illness (33.7 percent of the total inequality observed, hospital admission (27.8 percent, and self-assessed deterioration of health compared to a year ago (31.9 percent. The effect of being female and aged 60 years or older was by far the strongest demographic determinant of inequality across all five types of health outcome. Having a low socioeconomic status as measured by income quintile, education and work status were the main contributors disadvantaging the poor in self-rated health compared to a year ago (47.1 percent and self-assessed health compared to peers (47.4 percent. Residence in the rural Northeast and rural North were the main regional contributors to inequality in self

    A bacterial community analysis, using a culture-independent method (polymerase chain reaction-denaturing gradient gel electrophoresis), detected 17 species of bacteria including species of the genera Tetragenococcus, Lactobacillus, Pediococcus, Weissella Halanaerobium, Clostridium, and Sphingomonas in a traditional salty-fermented fish paste known as pla-ra or pa-daek in Thailand and Laos, which is used as a storage-stable multi-purpose seasoning. The representative genus of lactic acid bacteria seemed to vary in the 10 products collected from Thailand and Laos. Tetragenococci were common in products from central Thailand and Vientiane in Laos which had salinities of not less than 11% and pH values ranging from 5.6 to 6.1. However, lactobacilli were common in products from northern Thailand which had the lowest salinities (8.3–8.6%) and pH values (4.5–4.8) of all the samples examined. Two Lactobacillus and one Tetragenococcus species were detected in one product from northeastern Thailand containing 10% salt. These results suggest that salinity in pla-ra/pa-daek is an important determinant of the representative genus of lactic acid bacteria such as, Tetragenococcus or Lactobacillus. Additionally, differences in the acidity between these two groups seemed to be related to the production of d-/l-lactic acid in the lactic acid bacteria in each product. This is the first study to report a correlation between bacterial community structure and taste components in pla-ra/pa-daek products from various regions. This scientific work on a traditional fermented food will be useful in helping local producers meet differing consumer preferences in various regions. PMID:25918672

    Monitoring changes in adolescent sexual risk behaviors and sexually transmitted infections is critical for evaluating the effectiveness of human immunodeficiency virus and other prevention programs, but population-based data on adolescents in Thailand are limited. We report findings from 2 cross-sectional surveys conducted in 1999 and 2002 among 15-to 21-year-old vocational students. In 1999 and 2002, 1725 and 966 students, respectively, were interviewed using computer-assisted self-interview methods. Urine samples were collected and tested for Chlamydia trachomatis and Neisseria gonorrhoeae by polymerase chain reaction. From 1999 to 2002 C. trachomatis prevalence increased from 3.2% to 7.5% (P partners among both men (3.4-4.7, P = 0.01) and women (2.5-3.3, P partners among men (1.1-2.1, P use decreased significantly among women with casual partners (43%-19%, P = 0.03) but not among men (25%-31%, P = 0.31). Our study identified important increases in the prevalence of chlamydial infection and in sexual risk behaviors among Thai adolescents over a 3-year period. These findings are consistent with other studies suggesting profound social changes are changing norms of adolescent sexual behavior in Thailand, and highlight the need for adolescent sexual health services and prevention programming.

    The growing incidence of depression in developing countries, such as Thailand, is placing increasing pressure on public mental health services, and those living in rural areas have limited access to these services. Resilience is integral to the recovery of people with depression and to caregivers. This parallel-group randomised controlled trial evaluated the effectiveness of a guided self-help manual in improving resilience in adults diagnosed with moderate depression and their primary caregivers in Thailand. Our findings provide preliminary evidence that the approach is an effective way of increasing resilience in adults with depression and their caregivers.

    Full Text Available Any activities conducted at the boundary area between countries will only be successful if the community of speakers has mutual understanding in terms of language, especially those involving business. This study focuses on a community in the northern part of Malaysia near the Thailand border where majority of people are bilingual in Malay and Thai. This study aims to investigate the patterns of language used by speakers in the Malaysia-Thailand border, in the context of language maintenance and language shift. Both countries use different languages; with Malaysians use Malay and the Thais use Thai language. In this cross-border context, activities pertaining to business, visit or personal matters will have an impact on the development of the two languages. This study presents the findings on the language choice from a survey involving 202 respondents that was conducted in two border towns at the Malaysia-Thailand border, namely Rantau Panjang (Malaysian side and Golok (Thailand side. By utilizing the domain concept that was introduced by Fishman (1972, this study focuses on two domains namely, business and family. In addition to the questionnaire, participant observations and interviews were also conducted as supplements. The data on the patterns of language choice were analyzed statistically. The findings show that although Malaysians and Thais speak two different languages, Kelantanese dialect, which is a variety of the standard Malay, was the most dominant language at the border. This study also found that age was a significant factor in determining the patterns of language use. The younger generations were using Kelantanese dialect and Thai language in domains where older people would only use Kelantanese dialect. This points to the occurrence of language shift at the border. However, the community at the Thai side of the border tends to choose Kelantanese dialect in their daily activities, which seems to indicate language maintenance in

    Full Text Available Taxonomic uncertainty of the Asian tree frog Polypedates leucomystax complex presents the challenging task of inferring its biogeographical history. Here, we describe its dispersion and the genetic relationships among different populations in Thailand, where we connect the population of the P. leucomystax complex of the Sunda Islands to the Indochina (mainland population based on analyses of 266 sequences of the mitochondrial cytochrome c oxidase subunit I (COI gene. Our maternal genealogy implies that there are four well-supported lineages in Thailand, consisting of Northern A (clade A: Polypedates sp., Nan (clade B: P. cf. impresus, Southern (clade C: P. cf. leucomystax and Northern D (clade D: P. cf. megacephalus, with Bayesian posterior probability >0.9. Phylogeny and haplotype networks indicate that clades A, B and D are sympatric. In contrast, clade C (P. cf. leucomystax and clade D (P. cf. megacephalus are genetically divergent due to the geographical barrier of the Isthmus of Kra, resulting in an allopatric distribution. Climatic conditions, in particular differences in rainfall on each side of the Isthmus of Kra, may play an important role in limiting the immigration of both clades. For the within-populations of either clades C or D, there was no significant correlation between geographic and genetic distance by the isolation-by-distance test, indicating intraspecific-dispersal of each clade. Population expansion occurred in clade C, whereas clade D showed a constant population. Taken together, the P. leucomystax complex in South East Asia may have diversified under climatic pressure, leading to allopatric and/or sympatric speciation.

    Treatment for tobacco dependence is not available in many low-resource settings, especially in developing countries. To test the impact of a novel mix of monetary and social incentives on smoking abstinence in rural communities of Thailand. An RCT of commitment contracts and team incentives for rural smokers to quit smoking. Smokers were not blinded to treatment status, although the assessor of the biochemical urine test was. All adult smokers living in the study area were eligible to participate; 215 adult smokers from 42 villages in Nakhon Nayok province, Thailand, participated. Fourteen smokers who lacked teammates were dropped. A total of 201 smokers were assigned to a two-person team, and then randomly assigned by team (in a 2:1 ratio) with computer-generated random numbers to receive smoking-cessation counseling (control group) or counseling plus offer of a commitment contract, team incentives, and text message reminders for smoking cessation at 3 months (intervention group). The primary outcome was biochemically verified 7-day abstinence at 6 months, assessed on an intention-to-treat basis. Secondary outcomes include study participation, biochemically verified abstinence at 3 months, self-reported abstinence at 14 months, and the incremental cost per quitter of the intervention, nicotine gum, and varenicline in Thailand. Data were collected in 2010-2011 and analyzed in 2012. The trial enrolled 215 (10.5%) of 2055 smokers. The abstinence rate was 46.2% (61/132) in the intervention group and 14.5% (10/69) in the control group (adjusted OR 7.5 [3.0-18.6]) at 3 months; 44.3% (58/131) and 18.8% (13/69) at the primary end point of 6 months (adjusted OR 4.2 [1.8-9.7]); and 42.0% (55/131) and 24.6% (17/69) at 14 months (adjusted OR 2.2 [1.0-4.8]). The purchasing power parity-adjusted incremental cost per quitter from the intervention is $281 (95% CI=$187, $562), less than for nicotine gum ($1780, 95% CI=$1414, $2401) or varenicline ($2073, 95% CI=$1357, $4388) in

    Vitamin A deficiency (VAD) is the most common cause of childhood blindness in the developing world. It is estimated that by giving adequate vitamin A, in vitamin A deficient populations, child mortality from measles can be reduced by 50%, and mortality from diarrheal disease by 40%. Overall mortality in children 6-59 months of age can be reduced by 23%. This paper reported results from a study of vitamin A status and malnutrition of the minority ethnic group of Karen hill tribe children aged 1-6 years in the north of Thailand. All children aged 1-6 years (N = 158; 83 boys, 75 girls) from the three Karen villages (Mae Hae Tai, Mae Yot, Mae Raek) of Mae Chaem district in the north of Thailand were studied. The Karen is the largest mountain ethnic minority ("hill tribe") group in Thailand. All children were examined by a qualified medical doctor and were assessed for their vitamin A intakes using 24 hours dietary recall. Thai food composition table from Ministry of Health, Thailand were used as references. The results were compared with the Thai Recommended Dietary Allowances. Children aged 1-3 years and 4-6 years were separately analysed due to the differences in Thai Recommended Dietary Allowances between the two age groups. A whole blood of 300 microL was obtained by "fingerstick" for determination of serum vitamin A. Community or village's vitamin A status was assessed by using Simplified Dietary Assessment (SDA) method and Helen Keller International (HKI) food frequency method. Descriptive statistics were used to analyse the data. All families of the study boys and girls had income lower than the Thailand poverty line (US $ 1,000/year). On average, 63% of children from Mae Hae Tai village, 1.5% of children from Mae Yot village and none of children from Mae Raek village had serum vitamin AKaren children in Mae Chaem district, recommendations were made as follow: (1) increased use of fat and oil, particularly in areas with high risk of VAD; (2) more general work

    There has been a long-running debate as to whether sexual cultures in sub-Saharan Africa are permissive or characterised by restrictive rules, rituals and self-restraint. This paper, based on participant observation data, outlines the main features of sexual culture in rural northern Tanzania and highlights both permissive and restrictive norms and expectations for young people. It also illustrates how sexual beliefs are socially constructed and subject to social change. Sexual activity is constrained by clear norms of school pupil abstinence, female sexual respectability and taboos around the discussion of sex. However, these norms are incompatible with several widely held expectations: that sexual activity is inevitable unless prevented, sex is a female resource to be exploited, restrictions on sexual activity are relaxed at festivals, and masculine esteem is boosted through sexual experience. Differential commitment to these norms and expectations reflects conflicts between generations and genders. Young people appear to manage the contradictions in these norms by concealing their sexual relationships. This almost certainly contributes to their short duration and the high levels of partner change, since relationships are not reinforced through social recognition and there is little scope to develop intimacy through non-sexual contacts.

    Biomass-burning (BB) aerosols are the significant contributor to the regional/global aerosol loading and radiation budgets. BB aerosols affect the radiation budget of the earth and atmosphere by scattering and absorbing directly the incoming solar and outgoing terrestrial radiation. These aerosols can exert either cooling or warming effect on climate, depending on the balance between scattering and absorption. BB activities in the form of wildland forest fires and agricultural crop burning are very pronounced in the Indochina peninsular regions in Southeast Asia mainly in spring (late February to April) season. The region of interest includes Doi Ang Khang (19.93° N, 99.05° E, 1536 msl) in northern Thailand, as part of the Seven South East Asian Studies (7-SEAS)/BASELInE (Biomass-burning Aerosols & Stratocumulus Environment: Lifecycles & Interactions Experiment) campaign in 2013. In this study, for the first time, the direct aerosol radiative effects of BB aerosols over near-source BB emissions, during the peak loading spring season, in northern Indochina were investigated by using ground-based physical, chemical, and optical properties of aerosols as well as the aerosol optical and radiative transfer models. Information on aerosol parameters in the field campaign was used in the OPAC (Optical Properties of Aerosols and Clouds) model to estimate various optical properties corresponding to aerosol compositions. Clear-sky shortwave direct aerosol radiative effects were further estimated with a raditive transfer model SBDART (Santa Barbara DISORT Atmospheric Radiative Transfer). The columnar aerosol optical depth (AOD500) was found to be ranged from 0.26 to 1.13 (with the mean value 0.71 ± 0.24). Fine-mode (fine mode fraction ≈0.98, angstrom exponent ≈1.8) and significantly absorbing aerosols (columnar single-scattering albedo ≈0.89, asymmetry-parameter ≈0.67 at 441 nm wavelength) dominated in this region. Water soluble and black carbon (BC) aerosols mainly

    The objective of this study was to determine the prevalence of childhood obesity and elevated blood pressure (BP) in a rural population of northern Greece. In total, 572 schoolchildren between the age of 4 and 10 years were examined. Obesity was defined using three different standards: (1) body mass index (BMI) charts of the French society of Paediatrics (FR), selected because of the low cardiovascular risk profile and low prevalence of obesity in France; (2) United States BMI CDC charts (US), selected because of the high prevalence of childhood obesity in the USA; and the reference curves of the International Obesity Task Force (IOTF). Children with elevated BP were defined as BP > or = 95th percentile for age, gender and height, according to the Greek national charts. The prevalence of obesity for boys was 13.6% (IOTF), 23.7% (US) and 31.7% (FR); for girls 14.4% (IOTF), 21.1% (US) and 35.1% (FR). The prevalence of elevated BP was 7.9% (45 children). It was 5 to 6 times more common for obese than non-obese children to have elevated BP (relative risk of 5.2 to 6.2 and odds ratio 6.3 to 7.7). The results confirm the high prevalence of childhood obesity in Greece, in this study found to be more prevalent in rural than urban Greece. The IOTF criteria tend to underestimate obesity and may not be optimal for use in a primary clinical care setting where the approach is for health education and patient treatment, rather than purely epidemiological. The study also confirms a strong relationship between high BP and increased BMI.

    The article discusses some of the economic effects of war in northern Mozambique. It indicates how the historical and structural features of the economy of northern Mozambique restricted post-war reconstruction and post-war poverty alleviation. These features include the dominance of only a few cash crops for export, the absence of much rural trading, poor communication infrastructure, and weak political and state institutions. The specific nature of the internal war further weakened the stat...

    The taxonomic identity of the Trimeresurus (Popeia) popeiorum complex from the Isthmus of Kra and to the north was investigated. Several studies over the last decade have produced several specimens and associated mtDNA sequence data for a variety of individuals of the T. popeiorum and "T. sabahi" complexes. Here, we combine four mitochondrial genes (12S, 16S, ND4, and CytB) from all available specimens in GenBank with the addition of five new specimens collected from the mainland, Tanintharyi Region of Myanmar. Maximum Likelihood and Bayesian analyses identified that T. popeiorum sensu lato is paraphyletic with two geographically distinct clades: a northern clade representing populations from northern Myanmar, Laos and northern Thailand and a southern clade representing samples from the Tanintharyi Region and adjacent west Thailand. While the two clades have considerable genetic distance, they appear to be morphologically identical, leading to the hypothesis that the southern clade represents a cryptic, undescribed species. Because they appear to be cryptic species and the limitation of only five specimens from the southern lineage, this does not permit us to formally describe the new species. In accordance to past molecular studies, we uncovered paraphyly and lack of genetic support for the validity of taxa within the T. sabahi complex. However, we suggest recognizing these populations as subspecies within T. sabahi.

    Full text: Radiocarbon dating is widely used on organic samples, especially wood, charcoal and bone. Classical techniques use samples of several grams, but only a few milligrams is needed for measurements by Accelerator Mass Spectrometry (AMS). Palaeomagnetic techniques are readily applicable to the study of ancient kilns. Core samples are drilled from the walls and floors, and oriented before being detached and measured on a sensitive spinner magnetometer in a laboratory. Resolution of a quarter of a century at 95% confidence can be achieved in favourable circumstances but only at certain periods of time. Radiocarbon dating shows that the earliest stoneware ceramics are from the 11th - 12th centuries AD and palaeomagnetism indicates that many in-ground kilns are of this age. Kilns of this type, which were hollowed out in sediments near river banks or old terraces, are found near Sisatchanalai in north-central Thailand and near Luang Prabang in northern Laos; they are similar in age to the Khmer-type kilns found at Suphanburi in central Thailand. A different type of kiln, constructed of bricks and located above-ground, appears towards the end of the 13th century AD. One of the earliest surface kilns at Sisatchanalai has a well determined date of 1290 ± 15 AD (calibrated radiocarbon age, 95% confidence).There is an overlap of the two technologies; stratigraphy and palaeomagnetic results show that in-ground and above-ground brick kilns continue almost side-by-side throughout the 14th century AD. One of the latest in-ground kilns at Sisatchanalai has a date of 1410 ± 25 AD (calibrated radiocarbon age, 95% confidence). There are many brick kilns belonging to the l5th century AD at Sisatchanalai, and they appear then at other sites in north-central Thailand (e.g., Sukhothai and Phitsanulok) and in Burma (e.g., Lagumbyee). In-ground kilns continue to be used in northern Laos even in the 15th century AD. The latest brick kilns at Sisatchanalai are 16th and possibly 17th

    Indoor air quality in nursery schools is different from other schools and this has been largely ignored, particularly in rural areas. Urban and rural nursery schools have different environmental characteristics whose knowledge needs improvement. Thus, this study aimed to evaluate continuously the concentrations of CO2, CO, NO2, O3, CH2O and total VOC in three rural nursery schools and one urban, being the only one comparing urban and rural nurseries with continuous measurements, thus considering occupation and non-occupation periods. Regarding CO2, urban nursery recorded higher concentrations (739-2328 mg m(-3)) than rural nurseries (653-1078 mg m(-3)). The influence of outdoor air was the main source of CO, NO2 and O3 indoor concentrations. CO and NO2 concentrations were higher in the urban nursery and O3 concentrations were higher in rural ones. CH2O and TVOC concentrations seemed to be related to internal sources, such as furniture and flooring finishing and cleaning products. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Indoor air quality in nursery schools is different from other schools and this has been largely ignored, particularly in rural areas. Urban and rural nursery schools have different environmental characteristics whose knowledge needs improvement. Thus, this study aimed to evaluate continuously the concentrations of CO_2, CO, NO_2, O_3, CH_2O and total VOC in three rural nursery schools and one urban, being the only one comparing urban and rural nurseries with continuous measurements, thus considering occupation and non-occupation periods. Regarding CO_2, urban nursery recorded higher concentrations (739–2328 mg m"−"3) than rural nurseries (653–1078 mg m"−"3). The influence of outdoor air was the main source of CO, NO_2 and O_3 indoor concentrations. CO and NO_2 concentrations were higher in the urban nursery and O_3 concentrations were higher in rural ones. CH_2O and TVOC concentrations seemed to be related to internal sources, such as furniture and flooring finishing and cleaning products. - Highlights: • This is the only study comparing gaseous pollutants continuously measured in urban and rural nurseries. • Children's risk of exposure occurs mainly in the urban nursery school. • Outdoor air was the main determinant of CO, NO_2 and O_3 indoor concentrations. • There is a need to implement measures to reduce critical situations regarding IAQ. - Gaseous pollutant levels were higher in the urban nursery than in rural ones, except for O_3. High concentrations were due to lack of ventilation, outdoor air and internal sources.

    This article highlights the impact of Thailand's economic crisis on the state run Electricity Generating Authority of Thailand (EGAT) hydroelectric power developments plans. The three economic scenarios (rapid, moderate, slow) used by EGAT, and the moderate recovery scenario that the Thai government has instructed EGAT to use are discussed. The predicted rising of energy consumption, the delay to EGAT power development programme, plans for constructing plants using renewable energy, the supply of electricity from Laos, and future developments are considered. The restructuring of Thailand's electricity sector is reviewed, and Thailand's decision to request the assistance of the International Monetary Fund is noted. Thailand's power capability is briefly explored, and a diagram showing the transmission system and existing and future hydroelectric power plants is presented. (UK)

    Full Text Available Effective conservation of coastal marine mammals is largely dependent on reliable knowledge of their abundance, as well as the ecological and human factors driving their distribution. In developing countries, lack of resources and capacity frequently impedes research needed to estimate abundance and to determine the ecological requirements of coastal marine mammals and the impact of threats related to coastal development and fisheries. Over the course of five years, we developed practical research methods and trained local scientists in Thailand to use accepted line transect distance sampling methods for abundance assessment. The study focused on a little-known coastal and freshwater species found throughout Southeast Asia, namely the Irrawaddy dolphin, which has been sighted regularly along the coast of the eastern Gulf of Thailand. During five years of line transect boat surveys in Trat Province, the eastern-most province in Thailand, we found an average of 423 dolphins distributed within 12km of the coast. Compared to other abundance estimates of coastal Irrawaddy dolphins in Southeast Asia, this is a relatively large number. This population could extend into the northern coast of Cambodia, where surveys are currently being planned. The Thai government has begun talks with Cambodia about a transboundary marine protected area that would include areas in both countries where coastal Irrawaddy dolphins are found. Other analyses include photo-identification, modeling environmental factors that determine presence, determination of fresh vs. salt water foraging using stable isotopes, and an assessment of threats. Collaboration between scientists in Thailand, Cambodia and Vietnam is further needed to determine dolphin movement and habitat use across borders.

    A cross-sectional study of the association between occupational pig exposure and hepatitis E virus (HEV) infection in adult pig farmers and the general population who were not directly exposed to pigs was conducted in Nan Province, Thailand, from November 2010 to April 2011. All participants were interviewed to provide information on their job history, eating habits and other potential confounders. The prevalence of anti-HEV immunoglobulin G antibodies (IgG) among 513 subjects was 23.0%. Hand washing with water and soap was associated with a lower seroprevalence of HEV infection, whereas living in an area with frequent flooding (OR 1.64, 95% CI: 1.00-2.68) and consuming internal pig organs more than twice per week (OR 3.23, 95%CI: 1.15-9.01) were both associated with a higher seroprevalence of anti-HEV IgG. There was no association between HEV seroprevalence and frequent, direct occupational pig contact. © 2012 Blackwell Verlag GmbH.

    Northern South China Sea (SCS) is adjacent to major atmospheric mercury (Hg) emission source regions; however, studies concerning regional atmospheric Hg distribution and cycling are very limited. Accordingly, measurements of atmospheric Hg were conducted in March and April during the 2010 Dongsha Experiment to study its spatial and temporal distribution. Atmospheric Hg was measured at Hengchun and Dongsha Island (Taiwan), Da Nang (Vietnam), Chiang Mai (Thailand) and over the northern SCS. Atmospheric Hg concentrations ranged between 1.54 and 6.83 ng m-3, mostly higher than the Northern Hemisphere background value. Regional wind fields and backward trajectories indicated that the atmospheric Hg concentrations over northern SCS should principally reflect the export of the East Asian Hg emissions by northeast monsoon. However, significantly elevated Hg concentrations were always observed at Da Nang, possibly due to the influence of local Hg emissions. Chiang Mai is located in the intense biomass burning region in northern Thailand. Therefore, atmospheric Hg concentrations at Chiang Mai reflected the influence of regional biomass burning Hg emissions. Two dust storms were encountered at Dongsha Island, one on March 16 and the other on March 21, with atmospheric Hg enhancements. Compared with the 2008 summer values, elevated Hg levels were observed at Dongsha Island in the spring of 2010. Summer air masses were mainly from the deep SCS, representing relatively clean marine air. On the other hand, air masses were from the north in spring, passing eastern China or Taiwan prior to reaching Dongsha Island. Results of this research thus demonstrated the transport of atmospheric Hg from the East Asian continent to northern SCS by regional monsoon activity in spring, but special events, such as biomass burning and dust storms, can also cause enhancements of ambient Hg levels.

    The efficiency for carbonization by slow pyrolysis is still low in the current method studied using rice straw in Thailand and cashewnut shell in Brazil, however direct heating process yields better char yield of 17% as compared to indirect heating with 15% process using horizontal metal drum kiln.where as vertical kiln were mainly used in Brazil. Higher yield is made possible from Brasilian cashew nut shell to make oil and char. Carbon and energy balance was also carried out and the results were compared for the direct and indirect process. Burning by indirect draft gives better results like more char, faster process. Direct draft gives less char, but higher quality (higher C and H2). Also a lot of straw is left unburnt in the direct draft kiln, because of bad temperature distribution and flow inside. The kiln design is found to be more suitable for indirect draft rather than direct draft. Both methods still give rice straw charcoal that has low calorific value with an output char LHV of 4337 kcal/kg as compared to fresh rice straw of 3412 kcal/kg. In the direct heating method output char is enriched to 45% with a still unburnt rice straw left out as compared to indirect heating method with carbon enrichment of 39%. There is a loss of 13% of carbon through the ash in the both the methods. The carbon content in the condensate is in the order of 18.5% for the indirect process as compared to 13.9% in the direct process due to less exhaust and carbon enrichment inside the kiln. There is a loss of 43% of carbon in the exhaust from indirect heating process as compared to direct heating process which is reduced to 26%. The energy balance predicts a heat loss of 14% in exhaust gases. A practical small scale slow pyrolysis project was developed to meet rural energy and heat requirements. to make the clean energy from waste resources possible by the joint project. (author)

    Gemstone commercial is a high revenue for Thailand especially ruby and sapphire. Moreover, Phrae is a potential gem field located in the northern part of Thailand. The studies of spectroscopic properties are mainly to identify gemstone using advanced techniques (e.g. UV-Vis-NIR spectrophotometry, FTIR spectrometry and Raman spectroscopy). Typically, UV-Vis-NIR spectrophotometry is a technique to study the cause of color in gemstones. FTIR spectrometry is a technique to study the functional groups in gem-materials. Raman pattern can be applied to identify the mineral inclusions in gemstones. In this study, the natural sapphires from Ban Bo Kaew were divided into two groups based on colors including blue and green. The samples were analyzed by UV-Vis-NIR spectrophotometer, FTIR spectrometer and Raman spectroscope for studying spectroscopic properties. According to UV-Vis-NIR spectra, the blue sapphires show higher Fe3+/Ti4+ and Fe2+/Fe3+ absorption peaks than those of green sapphires. Otherwise, green sapphires display higher Fe3+/Fe3+ absorption peaks than blue sapphires. The FTIR spectra of both blue and green sapphire samples show the absorption peaks of -OH,-CH and CO2. The mineral inclusions such as ferrocolumbite and rutile in sapphires from this area were observed by Raman spectroscope. The spectroscopic properties of sapphire samples from Ban Bo Kaew, Phrae Province, Thailand are applied to be the specific evidence for gemstone identification.

    The US Department of Energy has been encouraging other countries to consider US coal and coal technologies in meeting their future energy needs. Thailand is one of three developing countries determined to be a potentially favorable market for such exports. This report briefly profiles Thailand with respect to population, employment, energy infrastructure and policies, as well as financial, economic, and trade issues. Thailand is shifting from a traditionally agrarian economy to one based more strongly on light manufacturing and will therefore require increased energy resources that are reliable and flexible in responding to anticipated growth. Thailand has extensive lignite deposits that could fuel a variety of coal-based technologies. Atmospheric fluidized-bed combustors could utilize this resource and still permit Thailand to meet emission standards for sulfur dioxide. This option also lends itself to small-scale applications suitable for private-sector power generation. Slagging combustors and coal-water mixtures also appear to have potential. Both new construction and refurbishment of existing plants are planned. 18 refs., 3 figs., 7 tabs.

  15. The marginalization of "small is beautiful": Micro-hydroelectricity, common property, and the politics of rural electricity provision in Thailand

    Science.gov (United States)

    Greacen, Christopher Edmund

    This study analyzes forces that constrain sustainable deployment of cost-effective renewable energy in a developing country. By many economic and social measures, community micro-hydro is a superior electrification option for remote mountainous communities in Thailand. Yet despite a 20 year government program, only 59 projects were built and of these less than half remain operating. By comparison, the national grid has extended to over 69,000 villages. Based on microeconomic, engineering, social barriers, common pool resource, and political economic theories, this study investigates first, why so few micro-hydro projects were built, and second, why so few remain operating. Drawing on historical information, site visits, interviews, surveys, and data logging, this study shows that the marginal status of micro-hydro arises from multiple linked factors spanning from village experiences to geopolitical concerns. The dominance of the parastatal rural electrification utility, the PEA, and its singular focus on grid extension are crucial in explaining why so few projects were built. Buffered from financial consequences by domestic and international subsidies, grid expansion proceeded without consideration of alternatives. High costs borne by villagers for micro-hydro discouraged village choice. PEA remains catalytic in explaining why few systems remain operating: grid expansion plans favor villages with existing loads and most villages abandon micro-hydro generators when the grid arrives. Village experiences are fundamental: most projects suffer blackouts, brownouts, and equipment failures due to poor equipment and collective over-consumption. Over-consumption is linked to mismatch between tariffs and generator technical characteristics. Opportunities to resolve problems languished as limited state support focused on building projects and immediate repairs rather than fundamentals. Despite frustrations, many remain proud of "their power plant". Interconnecting and selling

    2003-01-01

    Stroke is the third leading cause of death in Scotland after coronary heart disease and cancer and is a major cause of long-term disability. There is evidence in other clinical conditions such as asthma, diabetic retinopathy, and cancer that rural residents may have poorer outcomes, due to relative inaccessibility of health-service provision or because the disease is at a more advanced stage at diagnosis. However, the evidence-base for stroke care and outcomes in remote and rural areas is small and the subject matter is under-researched. This study was designed to examine, over a one-year period, the incidence and outcome of stroke occurring in the Highlands and Islands of Scotland, a large geographical area with many rural and remote settlements. The study explored whether stroke care and outcome was affected by remoteness and rurality. The study was a prospective, community-based, observational survey. Patients in Highland and the Islands (Orkney, Shetland and the Western Isles) suffering first-ever stroke during a 12-month period (from 1 May 2001 to 30 April 2002) were included. All practitioners from health and social care sectors, residential homes, voluntary and charitable organisations were encouraged to notify the researchers of any individual they suspected or knew had a first-ever stroke within the designated time period. Data on 'limitation in activities' (formerly 'level of disability') and service provision were collected using questionnaires and proformas at 1, 3 and 6 months post-stroke from several sources. These included individual patients and carers, health and social care professionals, residential homes, voluntary organisations, and charitable organisations. The analysis focused on location at time of follow up, limitation in activities and service provision. Outcomes were compared across different settlement categories. Settlements were classified as urban/accessible, remote rural and very remote, based on the Scottish Household Survey. In all

    This study investigated organophosphorus (OP) residues in vegetables from 27 farms, 106 markets, and 1 supermarket around Kwan Phayao Lake, Northern Thailand, between August and September 2013. Types of vegetables sampled were all vegetables cultivated or sold around the study site. The most common OP pesticides detected in farm samples were chlorpyrifos (50 %), malathion (31.8 %), monocrotophos (31.8 %), diazinon (13.6 %), omethoate (13.6 %), and dicrotophos (9.1 %). The most common OP pesticides detected in market samples were chlorpyrifos (33.9 %), diazinon (18.6 %), parathion-methyl (3.4 %), profenofos (3.4 %), primiphos-ethyl (3.4 %), and fenitrothion (1.7 %). The OP pesticides detected in supermarket samples were chlorpyrifos (33.3 %), and diazinon (66.7 %). Among the compounds detected, chlorpyrifos was detected in most of the vegetable samples from all sources. The highest chlorpyrifos level in farm samples were found in lemon balm (2.423 mg/kg) followed by Vietnamese coriander (0.835 mg/kg), and cowpea (0.027 mg/kg). The highest level in markets samples were found in garlic (7.785 mg/kg) followed by Chinese cabbage (2.864 mg/kg) and Vietnamese coriander (1.308 mg/kg). Residues from supermarket samples were found only in parsley (0.027 mg/kg). The findings showed that 16 samples (59.3 %) from farms and 14 samples (13.2 %) from markets contained OP residues at or above the maximum residue limits established by the European Union. It is concluded that awareness, safety education, and strict regulation of pesticide use are necessary.

    Increased intake of saturated fat and refined sugars underlies much of the problem of emerging obesity all over the world. This includes middle-income countries like Thailand, which are subject to successful marketing of Western fast foods especially targeted at adolescents. In this study we explore the socio-cultural influences on fast-food intake for non-metropolitan (rural and urban) adolescents in North East Thailand (Isan). Our questionnaire sample included 634 persons aged 15-19 years who are in and out of formal schooling and who are randomly representing upper, central and lower Isan. All were asked about their knowledge of fast-food health risks and their attitudes towards, and consumption of, fast food and traditional food. As well, we used several focus groups to obtain qualitative data to complement the information derived from the questionnaire. Some three quarters of sampled youth were aware that fast food causes obesity and half knew of the link to heart disease. About half consumed fast food regularly, induced by the appeal of 'modern' lifestyles, social events and marketing, as well as by the convenience, speed and taste. Nearly two-thirds thought that local foods should be more popular and these beliefs were more likely to be found among children from educated and urban families. Local foods already constitute a cultural resistance to fast-food uptake. We propose several methods to boost this resistance and protect the youth of Thailand against fast food and its many adverse health consequences.

  2. Prevalence and correlates of roll-your-own smoking in Thailand and Malaysia: Findings of the ITC-South East Asia Survey.

    Roll-your-own (RYO) cigarette use has been subject to relatively limited research, particularly in developing countries. This paper seeks to describe RYO use in Thailand and Malaysia and relate RYO use to smokers' knowledge of the harmfulness of tobacco. Data come from face-to-face surveys with 4,004 adult smokers from Malaysia (N = 2,004) and Thailand (N = 2000), collected between January and March 2005. The prevalence of any use of RYO cigarettes varied greatly between Malaysia (17%) and Thailand (58%). In both countries, any RYO use was associated with living in rural areas, older average age, lower level of education, male gender, not being in paid work, slightly lower consumption of cigarettes, higher social acceptability of smoking, and positive attitudes toward tobacco regulation. Among RYO users, exclusive use of RYO cigarettes (compared with mixed use) was associated with older age, female gender (relatively), thinking about the enjoyment of smoking, and not making a special effort to buy cheaper cigarettes if the price goes up. Finally, exclusive RYO smokers were less aware of health warnings (RYO tobacco carries no health warnings), but even so, knowledge of the health effects of tobacco was equivalent.

  3. Sex tourism in Thailand.

    Van Kerkwijk, C

    1992-01-01

    Many foreigners visit Thailand in search of sex. While long-distance tourism was long enjoyed by members of more privileged social classes, even the lower economical classes of Japan, Malaysia, Europe, America, and Australia can now afford to travel over long distances. This relatively new breed of tourist is more likely to be of lower socioeconomic and educational status and less likely to use condoms when having sex. An estimated 30,000 sex workers are active in Bangkok, of whom 7000/10,000 are females who work specifically in the tourism sector. 1/2-1/3 of the 600 commercial sex establishments in the city are visited by foreigners. Phuket, Pattaya, Koh Samui, and Chiangmai are also well-frequented by sex tourists. Overall, a large, diverse, inexpensive, and accessible commercial sex market exists in Thailand. One may meet sex workers quasi-ubiquitously and be assured to find someone capable of meeting one's sexual needs. With these attributes, Thailand strongly attracts tourists in search of sex. A certain degree of recklessness also prevails among those on vacation. Away from the peers and social mores of their native lands, tourists may engage in sexually activities without criticism. Likewise, Thai sex workers who cater to foreigners, especially females, enjoy more freedom and control in sexual relations than their peers who work among nationals. Neither single nor married women in Thailand are allowed much sexual freedom and are traditionally expected to be obliging docile, and submissive. The greater than normal personal latitude enjoyed by both sex worker and foreigner lead to more negotiation on condom use and overall lower use. As such, Thailand's commercial sex market with foreigners' involvement therein threatens to spread HIV to many other countries throughout the world.

    Physician scarcity in rural areas is a major obstacle to healthcare access, leading to health inequity worldwide. In Thailand, a special recruitment program of medical education [Collaborative Project to Increase Production of Rural Doctors (CPIRD)] was initiated with four different medical training tracks. No previous research has examined the rural retention of new medical graduates across the CPIRD tracks, compared with those receiving conventional medical education (Normal track). This study examines the public retention of rural physicians from different tracks of entry. A retrospective study was conducted in new medical graduates who entered Ministry of Public Health (MoPH) hospitals from January 2003 to October 2014, and followed up until June 2015, using administrative data from the Personnel Administration Division, MoPH. The CPIRD registry database was used to identify physicians' tracks of entry. Survival analyses and multiple logistic regression analyses were applied to compare the annual retention and the probability of 3-year retention of rural physicians. Results clearly demonstrated a high rural retention of CPIRD medical graduates, compared with their Normal track peers, regarding both lower annual resignation (HR 0.456, P rural retention were revealed across the different CPIRD tracks. Evidence from this study can be used as part of the information to reshape the physician production policy to reduce health inequity in rural areas. © The Author 2017.

    Full Text Available Abstract Background Over-prescribing of benzodiazepines appears common in many countries, a better understanding of prescribing practices and attitudes may help develop strategies to reduce prescribing. This study aimed to evaluate benzodiazepine prescribing behaviour and attitudes in general practitioners practising in Chiang Mai and Lampoon, Thailand. Methods Questionnaire survey of general practitioners in community hospitals, to estimate: i use of benzodiazepines for anxiety/insomnia, panic disorder, depression, essential hypertension, and uncomplicated low back pain and ii views on the optimal duration of benzodiazepine use. Results Fifty-five of 100 general practitioners returned the completed questionnaires. They reported use of benzodiazepines for anxiety/insomnia (n = 51, 93%, panic disorder (n = 43, 78%, depression (n = 26, 43%, essential hypertension (n = 15, 27 % and uncomplicated low back pain (n = 10, 18%. Twenty-eight general practitioners would prescribe benzodiazepines for non-psychiatric conditions, 17 for use as muscle relaxants. Seventy-five per cent, 62% and 29% of the general practitioners agreed or totally agreed with the use of benzodiazepines for insomnia, anxiety and depression, respectively. Practitioners agreed that prescribing should be less than one week (80%; or from 1 week to 1 month (47%; or 1 to 4 months (16%; or 4 to 6 months (5% or more than 6 months (2%. Twenty-five general practitioners (45% accepted that they used benzodiazepines excessively in the past year. Conclusion A considerable proportion of general practitioners in Chiang Mai and Lampoon, Thailand inappropriately use benzodiazepines for physical illnesses, especially essential hypertension and uncomplicated low back pain. However, almost half of them thought that they overused benzodiazepines. General practitioner's lack of time, knowledge and skills should be taken into account in improving prescribing behaviour and attitudes.

    The aim of this study was to investigate barriers to and supports for implementing a diabetes prevention education programme for community health-care workers (CHCWs) in Chiang Mai province, Thailand. The study also aimed to get preliminary input into the design of a tailored diabetes prevention education programme for CHCWs. Thailand has faced under-nutrition and yet, paradoxically, the prevalence of diseases of over-nutrition, such as obesity and diabetes, has escalated. As access to diabetes prevention programme is limited in Thailand, especially in rural and semi-urban areas, it becomes critical to develop a health information delivery system that is relevant, cost-effective, and sustainable. Health-care professionals (n = 12) selected from health centres within one district participated in in-depth interviews. In addition, screened people at risk for diabetes participated in interviews (n = 8) and focus groups (n = 4 groups, 23 participants). Coded transcripts from audio-taped interviews or focus groups were analysed by hand and using NVivo software. Concept mapping illustrated the findings. Health-care professionals identified potential barriers to programme success as a motivation for regular participation, and lack of health policy support for programme sustainability. Health-care professionals identified opportunities to integrate health promotion and disease prevention into CHCWs' duties. Health-care professionals recommended small-group workshops, hands-on learning activities, case studies, and video presentations that bring knowledge to practice within their cultural context. CHCWs should receive a credit for continuing study. People at risk for diabetes lacked knowledge of nutrition, diabetes risk factors, and resources to access health information. They desired two-way communication with CHCWs. Formative research supports the need for an effective, sustainable programme to support knowledge translation to CHCWs and at-risk populations in the

    Full Text Available Abstract Background In Thailand, rabies remains a neglected disease with authorities continuing to rely on human death statistics while ignoring the financial burden resulting from an enormous increase in post-exposure prophylaxis. Past attempts to conduct a mass dog vaccination and sterilization program have been limited to Bangkok city and have not been successful. We have used molecular epidemiology to define geographic localization of rabies virus phylogroups and their pattern of spread in Thailand. Methods We analyzed 239 nucleoprotein gene sequences from animal and human brain samples collected from all over Thailand between 1998 and 2002. We then reconstructed a phylogenetic tree correlating these data with geographical information. Results All sequences formed a monophyletic tree of 2 distinct phylogroups, TH1 and TH2. Three subgroups were identified in the TH1 subgroup and were distributed in the middle region of the country. Eight subgroups of TH2 viruses were identified widely distributed throughout the country overlapping the TH1 territory. There was a correlation between human-dependent transportation routes and the distribution of virus. Conclusion Inter-regional migration paths of the viruses might be correlated with translocation of dogs associated with humans. Interconnecting factors between human socioeconomic and population density might determine the transmission dynamics of virus in a rural-to-urban polarity. The presence of 2 or more rabies virus groups in a location might be indicative of a gene flow, reflecting a translocation of dogs within such region and adjacent areas. Different approaches may be required for rabies control based on the homo- or heterogeneity of the virus. Areas containing homogeneous virus populations should be targeted first. Control of dog movement associated with humans is essential.

    Wood-plastic composites produced by means of radiation-induced polymerization of monomers impregnated into the wood have been the subject of study in many laboratories throughout the world. In general the processes are similar, and the differences that occur are due to variations in technique applied to the particular species of wood available in each country. In Thailand, treatment to improve the quality of wood is being carried out by scientists at the Forest Products Research Division of the Royal Forest Department, Ministry of Agriculture, with the aim of obtaining products which can stand up to weathering and termite attack. On the basis of their experience, certain types of wood suitable for impregnation have been selected for our study. The Office of Atomic Energy for Peace began studying the impregnation-irradiation of certain types of Thai wood in the hope that it might result in better utilization of poor quality wood. The use of irradiated-impregnated wood in Thailand is not necessary at present, since many different varieties of hard wood are available. The production of plywood does not even meet the demand of the local market, thus the introduction of this new technique is not an attractive proposal for the time being.

    Nuclear energy in Thailand can be highlighted when the Office of Atomic Energy for Peace (OAEP) was established since 1961 for taking role of nuclear safety regulation, conducting research and promotion for peaceful uses of nuclear energy. Its main facilities were the 1 megawatt Thai Research Reactor-1 (TRR-1) and the Cobalt-60 Gamma Irradiator. Since then there have been substantial progress made on utilization of nuclear energy in various institutions and in private sectors. Nowaday, there are around 500 units of nuclear energy users in Thailand, i.e. 100 units in medicine, 150 units in education and 250 units in industry. In terms of nuclear power for electricity generation, the Electricity Generating Authority of Thailand (EGAT) has conducted the activities to support the nuclear power plant project since 1972 however, because there is widespread public concerned about nuclear safety, waste disposal and recently economic problems in Thailand, nuclear energy option is not put in immediate plan for alternative energy resource. Within the short future, increased in economical, demand fir electricity and safe operation of nuclear plants will likely be demonstrated and recognized. Nuclear energy should remain as an option in the long-term energy strategies for Thailand. (author)

    2012-01-01

    This paper aims to contribute to understanding of emergent gender/sexual identities in Thailand. Thailand has become a popular destination for sex change operations by providing the medical technology for a complete transformation, with relatively few procedures and satisfactory results at a reasonable price. Data were gathered from 24 transsexual male-to-female sex workers working in Pattaya and Patpong, well-known sex-tourism hot spots in Thailand. Findings suggest the emergence of new understandings of gender/sexual identity. Sex-tourism/sex work significantly illuminates the process through which gender is contested and re-imagined. The coming together of cultures in Thailand's sex industry, coupled with advances in medical technology, has resulted in the emergence of new concepts of gender.

    After decades of providing a dense network of quality medical care, Germany is facing an increasing shortage of medical doctors in rural areas. Current graduation rates of generalists do not counterbalance the loss due to retirement. Informed by international evidence, different strategies to ensure rural medical care are under debate, including innovative teaching approaches during undergraduate training. The University of Magdeburg in Saxony-Anhalt was the first medical school in Germany to offer a rural elective for graduate students. During the 2014 summer semester, 14 medical students attended a two-weekend program in a small village in Northern Saxony-Anhalt that allowed them to become more familiar with a rural community and rural health issues. The elective course raised a series of relevant topics for setting up rural practice and provided students with helpful insight into living and working conditions in rural practice. Preliminary evaluations indicate that the rural medicine course allowed medical students to reduce pre-existing concerns and had positive impact on their willingness to set up a rural medical office after graduation. Even short-term courses in rural practice can help reduce training-related barriers that prevent young physicians from working in rural areas. Undergraduate medical training is promising to attenuate the emerging undersupply in rural areas.

    Emulsion is normally present in oil due to the mixing occurring during oil recovery. The formation of emulsion can cause some problems in production and transportation. Viscosity and stability of emulsion play a key roles in oil transportation and separation to meet sales specification. Therefore, the aims of this research are to measure the viscosity of oil an emulsion and to evaluate the stability of emulsion of light oil from Fang oilfield in Thailand. The parameters of this study are temperature, shear rate and water cut ranging from 50 to 80 °C, 3.75 to 70 s-1 and 0 to 60%, respectively. These effects of parameters on viscosity and stability of emulsion are required for the design of the process and to increase oil production with various conditions. The results shows that viscosity decreases as temperature and shear rate increase. In contrast, viscosity becomes higher when water cut is lower. Furthermore, droplet sizes of water-in-oil emulsion at different conditions are investigated the stability of emulsion. The droplet sizes become smaller when high shear rate is applied and emulsion becomes more stable. Furthermore, correlations are developed to predict the viscosity and stability of the oil and emulsion from Thailand.

    Outbreaks of highly pathogenic avian influenza have occurred and have been studied in a variety of ecological systems. However, differences in the spatial resolution, geographical extent, units of analysis and risk factors examined in these studies prevent their quantitative comparison. This study aimed to develop a high-resolution, comparative study of a common set of agro-environmental determinants of avian influenza viruses (AIV) in domestic poultry in four different environments: (1) lower-Northern Thailand, where H5N1 circulated in 2004-2005, (2) the Red River Delta in Vietnam, where H5N1 is circulating widely, (3) the Vietnam highlands, where sporadic H5N1 outbreaks have occurred, and (4) the Lake Alaotra region in Madagascar, which features remarkable similarities with Asian agro-ecosystems and where low pathogenic avian influenza viruses have been found. We analyzed H5N1 outbreak data in Thailand in parallel with serological data collected on the H5 subtype in Vietnam and on low pathogenic AIV in Madagascar. Several agro-environmental covariates were examined: poultry densities, landscape dominated by rice cultivation, proximity to a water body or major road, and human population density. Relationships between covariates and AIV circulation were explored using spatial generalized linear models. We found that AIV prevalence was negatively associated with distance to the closest water body in the Red River Delta, Vietnam highlands and Madagascar. We also found a positive association between AIV and duck density in the Vietnam highlands and Thailand, and with rice landscapes in Thailand and Madagascar. Our findings confirm the important role of wetlands-rice-ducks ecosystems in the epidemiology of AI in diverse settings. Variables influencing circulation of the H5 subtype in Southeast Asia played a similar role for low pathogenic AIV in Madagascar, indicating that this area may be at risk if a highly virulent strain is introduced.

    Biomass burning (BB) frequently occurs in SouthEast Asia (SEA), which significantly affects the air quality and could consequently lead to adverse health effects. The aim of this study was to characterize particulate matter (PM) and black carbon (BC) emitted from BB source regions in SEA and their potential of deposition in the alveolar region of human lungs. A 31-day characterization of PM profiling was conducted at the Doi Ang Khang (DAK) meteorology station in northern Thailand in March 2013. Substantial numbers of PM (10147 +/- 5800 # per cubic centimeter) with a geometric mean diameter (GMD) of 114.4 +/- 9.2 nm were found at the study site. The PM of less than 2.5 micron in aerodynamic diameter (PM sub 2.5) hourly-average mass concentration was 78.0 +/- 34.5 per cubic microgram whereas the black carbon (BC) mass concentration was 4.4 +/- 2.6 micrograms per cubic meter. Notably, high concentrations of nanoparticle surface area (100.5 +/- 54.6 square micrometers per cubic centimeter) emitted from biomass burning can be inhaled into the human alveolar region. Significant correlations with fire counts within different ranges around DAK were found for particle number, the surface area concentration of alveolar deposition, and BC. In conclusion, biomass burning is an important PM source in SEA, particularly nanoparticles, which has high potency to be inhaled into the lung environment and interact with alveolar cells, leading to adverse respiratory effects. The fire counts within 100 to 150 km shows the highest Pearson's r for particle number and surface area concentration. It suggests 12 to 24 hr could be a fair time scale for initial aging process of BB aerosols. Importantly, the people lives in this region could have higher risk for PM exposure.

    We report a forensic entomology case associated with human myiasis in Chiang Mai Province, northern Thailand. The remains of a 53-yr-old-male were concurrently infested with third instars of the two blow fly species, Chrysomya megacephala (F.) and Chrysomya rufifacies (Macquart), near a severe tumor lesion presented on the lower right leg. The presence of third instars, approximately 5 d old, on the day following postmortem indicated that myiasis occurred before death. This is the first report of both fly species acting as a myiasis-producing agent in Thailand. Unsynchronized data between the age of fly larvae due to myiasis premortem and verified age/ condition of the corpse suggest a potential complication and error in the estimation of postmortem interval if other predisposition fly infestations are not considered.

    Full Text Available BACKGROUND: HIV prevalence among men who have sex with men (MSM and transgender (TG persons is high and increasing in Chiang Mai, northern Thailand. OBJECTIVES: To describe demographic, socioeconomic, sexual behavior and interest in future HIV prevention trials among gay and bisexual MSM and TG presenting for HIV testing (VCT and pre-screening for the iPrEx pre-exposure chemoprophylaxis trail. METHODS: In 2008-09, MSM/TG participants attending VCT were interviewed and tested for HIV and STI. Univariate and multivariate regression analyses were done to assess associations with HIV infection. RESULTS: A total of 551 MSM clients (56.1% gay, 25.4% TG, and 18.5% bisexual (BS were enrolled. The mean age was 23.9 years. HIV prevalence among MSM overall was 12.9% (71/551; 16.5% among gay men, 9.3% among TG, and 6.9% among BS. Consistent use of condom was low, 33.3% in insertive anal sex and 31.9% in receptive anal sex. Interest in participation was high, 86.3% for PrEP, 69.7% for HIV vaccine trials, but 29.9% for circumcision. HIV was independently associated with being gay identified, aOR 2.8, p = 0.037 and with being aged 25-29, aOR 2.7, p = 0.027. Among repeat testers, HIV incidence was 8.2/100 PY, 95% CI, 3.7/100PY to 18.3/100PY. CONCLUSION: HIV risks and rates varied by self-reported sexual orientation and gender identity. HIV was associated with sexual practices, age, and being gay-identified. These are populations are in need of novel prevention strategies and willing to participate in prevention research.

    This study examines the impact of economic growth, corruption, health, and poverty on environmental degradation for three countries from ASEAN, namely Indonesia, Malaysia, and Thailand using annual data over the period of 1994-2014. The relationship between environmental degradation (pollution) by carbon dioxide (CO 2 ) emissions and economic growth is examined along with some other variables, namely health expenditure, poverty, agriculture value added growth, industrial value added growth, and corruption. The ordinary least squares (OLS) method is applied as an analytical technique for parameter estimation. The empirical results reveal that almost all variables are statistically significant at the 5% level of significance, whereby test rejects the null hypotheses of non-cointegration, indicating that all variables play an important role in affecting the environment across countries. Empirical results also indicate that economic growth has significant positive impact, while health expenditures show significantly negative impact on the environment. Corruption has significant positive effect on environment in the case of Malaysia; while in the case of Indonesia and Thailand, it has insignificant results. However, for the individual analysis across countries, the regression estimate suggests that economic growth has a significant positive relationship with environment for Indonesia, while it is found insignificantly negative and positive in the case of Malaysia and Thailand, respectively, during the period under the study. Empirical findings of the study suggest that policy-makers require to make technological-friendly environment sequentially to surmount unregulated pollution, steady population transfers from rural areas to urban areas are also important, and poverty alleviation and better health provision can also help to improve the environment.

    In Thailand, pig production intensified significantly during the last decade, with many economic, epidemiological and environmental implications. Strategies toward more sustainable future developments are currently investigated, and these could be informed by a detailed assessment of the main trends in the pig sector, and on how different production systems are geographically distributed. This study had two main objectives. First, we aimed to describe the main trends and geographic patterns of pig production systems in Thailand in terms of pig type (native, breeding, and fattening pigs), farm scales (smallholder and large-scale farming systems) and type of farming systems (farrow-to-finish, nursery, and finishing systems) based on a very detailed 2010 census. Second, we aimed to study the statistical spatial association between these different types of pig farming distribution and a set of spatial variables describing access to feed and markets. Over the last decades, pig population gradually increased, with a continuously increasing number of pigs per holder, suggesting a continuing intensification of the sector. The different pig-production systems showed very contrasted geographical distributions. The spatial distribution of large-scale pig farms corresponds with that of commercial pig breeds, and spatial analysis conducted using Random Forest distribution models indicated that these were concentrated in lowland urban or peri-urban areas, close to means of transportation, facilitating supply to major markets such as provincial capitals and the Bangkok Metropolitan region. Conversely the smallholders were distributed throughout the country, with higher densities located in highland, remote, and rural areas, where they supply local rural markets. A limitation of the study was that pig farming systems were defined from the number of animals per farm, resulting in their possible misclassification, but this should have a limited impact on the main patterns revealed

    Full Text Available Abstract Background Vitamin D insufficiency is highly prevalent. Most of the studies concerning vitamin D status were generated from countries situated at temperate latitudes. It is less clear what the extent of vitamin D insufficiency is in countries situated in the tropics and how geographical regions within country would affect vitamin D status. In the present study, we investigated vitamin D status in Thais according to geographical regions and other risk factors. Methods Subjects consisted of 2,641 adults, aged 15 - 98 years, randomly selected from the Thai 4th National Health Examination Survey (2008-9 cohort. Serum 25 hydroxyvitamin D were measured by liquid chromatography/tandem mass spectrometry. Data were expressed as mean ± SE.

    Current smoking prevalence in Thailand decreased from 1991 to 2004 and since that time the prevalence has remained flat. It has been suggested that one of the reasons that the prevalence of current smoking in Thailand has stopped decreasing is due to the use of RYO cigarettes. The aim of this study was to examine characteristics of users of manufactured and RYO cigarettes and dual users in Thailand, in order to determine whether there are differences in the characteristics of users of the different products. The 2009 Global Adult Tobacco Survey (GATS Thailand) provides detailed information on current smoking patterns. GATS Thailand used a nationally and regionally representative probability sample of 20,566 adults (ages 15 years and above) who were chosen through stratified three-stage cluster sampling and then interviewed face-to-face. The prevalence of current smoking among Thai adults was 45.6% for men and 3.1% for women. In all, 18.4% of men and 1.0% of women were current users of manufactured cigarettes only, while 15.8% of men and 1.7% of women were current users of RYO cigarettes only. 11.2% of men and 0.1% of women used both RYO and manufactured cigarettes. Users of manufactured cigarettes were younger and users of RYO were older. RYO smokers were more likely to live in rural areas. Smokers of manufactured cigarettes appeared to be more knowledgeable about the health risks of tobacco use. However, the difference was confounded with age and education; when demographic variables were controlled, the knowledge differences no longer remained. Smokers of manufactured cigarettes were more likely than dual users and those who used only RYO to report that they were planning on quitting in the next month. Users of RYO only appeared to be more addicted than the other two groups as measured by time to first cigarette. There appears to be a need for product targeted cessation and prevention efforts that are directed toward specific population subgroups in Thailand and

    The larval morphology and developmental rate of Chrysomya megacephala (F.) and Chrysomya rufifacies (Macquart), the two most forensically important blowfly species in Thailand, are presented. Morphological comparison of the third instar of both species revealed different characteristics (e.g., body appearance, cephalopharyngeal skeleton, dorsal cuticular spines between the prothorax and mesothorax, and feature of the posterior spiracle), thereby, allowing correct identification. A data analysis was conducted in Chiang Mai province, Northern Thailand during 2000-2001 on the developmental rate of both flies under natural ambient temperature and a natural light-dark photoperiod. The results indicated that larvae of C. megacephala developed more rapidly in April, pupariation initiated at 84 h at temperatures averaging 31.4 degrees C, and the larvae grew slower in the rainy season and winter. Similarly, rapid development of C. rufifacies larvae appeared in the summer, with a pupariation period as short as 96 h in June (average temperature 27.4 degrees C). Analysis of the median body length of C. megacephala and C. rufifacies larvae in different seasons of the years 2000-2001 in Thailand revealed that both species developed rapidly in the summer; pupariation of C. rufifacies initiated at 144 h, while C. megacephala initiated pupariation at 156 h. This information is potentially useful for estimating the postmortem interval of a corpse in forensic investigations, where the corpse becomes infesting with these fly species.

    Full Text Available OBJECTIVE: This study aims to determine factors associated with levels of condom use among heterosexual Thai males in sex with regular partners and in sex with casual partners. METHODS: The data used in this study are from the national probability sample of the 2006 National Sexual Behavior Study, the third nationally representative cross-sectional survey in Thailand. A subtotal of 2,281 men were analyzed in the study, including young (18-24 and older (25-59 adults who were residents of rural areas of Thailand, non-Bangkok urban areas, and Bangkok. Two outcomes of interest for this analysis are reported condom use in the past 12 months by males in relationships with the most recent regular and casual partners who were not sex workers. Chi-square statistics, bivariate regressions and the proportional odds regression models are used in the analysis. RESULTS: Condom use for men with their regular partner is revealed to be positively related to education, knowledge of condom effectiveness, and pro-condom strategy, and negatively related to non-professional employment, status of registered marriage, and short relationship duration. Condom use with casual partner is positively determined by education, condom knowledge, non-professional occupation, short relationship duration, and lack of history of paid sex. CONCLUSION: The national survey emphasized the importance of risk perceptions and condom motivations variables in explaining condom use among men in Thailand. These factors include not only education and knowledge of condom effectiveness and pro-condom strategy but also types of partners and their relationship context and characteristics. Program intervention to promote condom use in Thailand in this new era of predominant casual sex rather than sex with sex workers has to take into account more dynamic partner-based strategies than in the past history of the epidemics in Thailand.

    Full Text Available The Khok Kruat Formation is the upper part of the Khorat Group, which consists of upper Lower Cretaceous non-marine sedimentary rocks in northeastern Thailand. Many dinosaur footprints have been known from the upper Lower Cretaceous (Aptian–Albian Khok Kruat Formation at the Huai Dam Chum (Tha Uthen site, northeastern Thailand. Approximately 600 tracks occur in thin mudstone layer of the northern part of the outcrop at the Huai Dam Chum track site. Two types of footprints, small-sized theropod and crocodylomorph are imprinted with mud cracks and ripple marks on the thin mud layer. Most of footprints are referred to cf. Asianopodus, and are imprinted by small-sized theropoda, probably ornithomimosauria. Theropod tracks are mainly separated into two groups, Group A and Group B. From ichnological viewpoints, the small-sized theropod track assemblage indicates the herd behaviour and its idiosyncratic group composition. In particular, the histogram of size-frequency measurements of Group A shows the anomalous bimodal distribution. We consider that there are two hypotheses; the first one is due to the male-female difference, and the second is a result of the different growing stage.

  11. The capacity to adapt?: communities in a changing climate, environment, and economy on the northern Andaman coast of Thailand

    Full Text Available The health and productivity of marine ecosystems, habitats, and fisheries are deteriorating on the Andaman coast of Thailand. Because of their high dependence on natural resources and proximity to the ocean, coastal communities are particularly vulnerable to climate-induced changes in the marine environment. These communities must also adapt to the impacts of management interventions and conservation initiatives, including marine protected areas, which have livelihood implications. Further, communities on the Andaman coast are also experiencing a range of new economic opportunities associated in particular with tourism and agriculture. These complex and ongoing changes require integrated assessment of, and deliberate planning to increase, the adaptive capacity of communities so that they may respond to: (1 environmental degradation and fisheries declines through effective management interventions or conservation initiatives, (2 new economic opportunities to reduce dependence on fisheries, and (3 the increasing impacts of climate change. Our results are from a mixed methods study, which used surveys and interviews to examine multiple dimensions of the adaptive capacity of seven island communities near marine protected areas on the Andaman coast of Thailand. Results show that communities had low adaptive capacity with respect to environmental degradation and fisheries declines, and to management and conservation interventions, as well as uneven levels of adaptive capacity to economic opportunities. Though communities and households were experiencing the impacts of climate change, especially storm events, changing seasons and weather patterns, and erosion, they were reacting to these changes with limited knowledge of climate change per se. We recommend interventions, in the form of policies, programs, and actions, at multiple scales for increasing the adaptive capacity of Thailand's coastal communities to change.

    Full Text Available Tourism activities affect the environment of different destinations, which is influenced by different tourists’ consumption. The objective of this study is to examine the relationship between inbound tourist expenditures and three main environmental dimensions, which are carbon dioxide emission from transport, energy demand, and water usage, in Thailand. This paper employs Vector Autoregressive (VAR models to determine the relationship of variables. Data from Ministry of Energy, Bank of Thailand, Metropolitan Electricity Authority, Provincial Waterworks Authority, National Statistical Office, Department of Tourism, and Tourism Authority of Thailand between 1988 and 2012 have been applied in the model. Note that, energy demand is represented by total electricity consumption of hotel and accommodation sector in Thailand, while water usage is represented by the total water consumption of tourists. This study found the relationships among tourists’ expenditures, carbon dioxide emission from transport, energy demand, and water usage. Therefore, the policies recommendations may be essential to prepare the optimal schemes and budgets for encountering the environmental impacts from tourism business expansion.

    Rural farming communities in northern Vietnam do not routinely practice vaccination for influenza A viruses (IAV) for either humans or poultry, which enables us to study transmission intensity via seroepidemiology. Using samples from a longitudinal cohort of farming households, we determined the number of symptomatic and asymptomatic human infections for seasonal IAV and avian A/H9 over 2 years. As expected, we detected virologically confirmed acute cases of seasonal IAV in humans, as well as large numbers of subclinical seroconversions to A/H1pdm [55/265 (21 %)], A/H3 [95/265 (36 %)] and A/H9 [24/265 (9 %)]. Five of the A/H9 human seroconverters likely represented true infections rather than heterosubtypic immunity, because the individuals seroconverted solely to A/H9. Among co-located poultry, we found significantly higher seroprevalance for A/H5 compared to A/H9 in both chickens and ducks [for northern study sites overall, 337/1105 (30.5 %) seropositive for A/H5 and 123/1105 (11.1 %) seropositive for A/H9].

    The primary objective of this pre-feasibility evaluation is to examine the economic and technical feasibility of replacing distillate fuel with local waste biomass in the village of Verkhni-Ozerski, Arkhangelsk Region, Russia. This village is evaluated as a pilot location representing the off-grid villages in the Russian Northern Territories. The U.S. Department of Energy (DOE) has agreed to provide technical assistance to the Ministry of Fuel and Energy (MFE). MFE has identified the Northern Territories as a priority area requiring NREL`s assistance. The program initially affects about 900 off-grid villages. Biomass and wind energy, and to a lesser extent small hydro (depending on resource availability) are expected to play the dominant role in the program, Geothermal energy may also have a role in the Russian Far East. The Arkhangelsk, Kariela, and Krasnoyarsk Regions, all in the Russian Northern Territories, have abundant forest resources and forest products industries, making them strong candidates for implementation of small-scale waste biomass-to-energy projects. The 900 or so villages included in the renewable energy program span nine administrative regions and autonomous republics. The regional authorities in the Northern Territories proposed these villages to MFE for consideration in the renewable energy program according to the following selection criteria: (a) Remote off-grid location, (b) high cost of transporting fuel, old age of existing power generation equipment, and (d) preliminary determination as to availability of alternative energy resources. Inclusion of indigenous minorities in the program was also heavily emphasized. The prefeasibility study demonstrates that the project merits continuation and a full feasibility analysis. The demonstrated rate of return and net positive cash flow, the willingness of Onegales and local/regional authorities to cooperate, and the immense social benefits are all good reasons to continue the project.

    To understand the impact of inter-annual climate change on vegetation-atmosphere mass and energy exchanges, it has become necessary to explore changes in leaf-out onset in response to climatic fluctuations. We examined the response of leaf-out and transpiration onset dates to soil moisture in a teak plantation in northern Thailand based on a 12-year leaf area index and sap flow measurements. The date of leaf-out and transpiration onset varied between years by up to 40 days, and depended on the initial date when the relative extractable water in a soil layer of 0-0.6 m (Θ) was greater than 0.2 being consistent with our previous results. Our new finding is that the delay in leaf-out and transpiration onset relative to the initial date when Θ > 0.2 increases linearly as the initial date on which Θ > 0.2 becomes earlier. The delay spans about 20 days in years when Θ > 0.2 occurs in March (the late dry season)-much earlier than usual because of heavy pre-monsoon rainfalls-while there is little delay in years when Θ > 0.2 occurs in May. This delay indicates the influence of additional factors on leaf-out onset, which controls the delay in the response of leaf-out to soil moisture increase. The results increased our knowledge about the pattern and extent of the changes in leaf phenology that occur in response to the inter-annual climate variation in tropical regions, where, in particular, such research is needed.

    Influenza is one of the most important leading causes of respiratory illness in the countries located in the tropical areas of South East Asia and Thailand. In this study the climate factors associated with influenza incidence in Chiang Mai Province, Northern Thailand, were investigated. Identification of factors responsible for influenza outbreaks and the mapping of potential risk areas in Chiang Mai are long overdue. This work examines the association between yearly climate patterns between 2001 and 2008 and influenza outbreaks in the Chiang Mai Province. The climatic factors included the amount of rainfall, percent of rainy days, relative humidity, maximum, minimum temperatures and temperature difference. The study develops a statistical analysis to quantitatively assess the relationship between climate and influenza outbreaks and then evaluate its suitability for predicting influenza outbreaks. A multiple linear regression technique was used to fit the statistical model. The Inverse Distance Weighted (IDW) interpolation and Geographic Information System (GIS) techniques were used in mapping the spatial diffusion of influenza risk zones. The results show that there is a significance correlation between influenza outbreaks and climate factors for the majority of the studied area. A statistical analysis was conducted to assess the validity of the model comparing model outputs and actual outbreaks.

    Full Text Available The number of visceral leishmaniasis (VL cases has increased over the past 10 years in Brazil, especially in the North and Northeast regions of the country. The aim of this study was to evaluate the urbanisation of VL vectors in Barcarena, Pará, an area in northern Brazil where VL is endemic. Sandflies were captured using Centers for Disease Control (CDC light traps along an urban-rural gradient. The CDC traps were installed inside hen houses at a height of 150 cm. A total of 5,089 sandflies were collected and 11 species were identified. The predominant species was Lutzomyia longipalpis (rate of 95.15%, which suggests its participation in the transmission of VL. A total of 1,451 Lu. longipalpis females were dissected and no Leishmania infections were detected. Most of the sandflies were captured at the border of a forest (88.25% and no flies were captured in the urban area, which suggests that transmission is still restricted to rural sites. However, the fact that a specimen was collected in an intermediate area indicates that urbanisation is a real possibility and that vector monitoring is important.

    2013-05-01

    The magnitude of 5.1 Mw earthquake occurred in San Sai District, Chiang Mai Province, Thailand in December 2006 was considered an uncommon event due to the fact that there was no statistical record of such significant earthquake in the area. Therefore the earthquake might have been associated with a potentially active fault zone within the area. The objective of this study is to measure soil gas radon across this unknown fault zone within the Chiang Mai Basin, northern Thailand. Two profiles traversing the expected fault zone of soil gas radon measurements have been monitored, using TASTRAK solid state track nuclear detectors (SSNTDs). Radon signals from three periods of measurement show a distinctive consistent spatial distribution pattern. Anomalous radon areas along the profiles are connected to fault locations previously interpreted from other geophysical survey results. The increased radon signal changes from the radon background level with the signal-to-background ratio above 3 are considered anomalous. Such pattern of radon anomaly supports the existence of the faults. The radon measurement, therefore is a powerful technique in mapping active fault zone.

    Full Text Available To ensure remote sensing MODIS hotspot (also known as active fire products or hotspots quality and precision in forest fire control and management in Thailand, an increased level of confidence is needed. Accuracy assessment of MODIS hotspots utilizing field survey data validation is described. A quantitative evaluation of MODIS hotspot products has been carried out since the 2007 forest fire season. The carefully chosen hotspots were scattered throughout the country and within the protected areas of the National Parks and Wildlife Sanctuaries. Three areas were selected as test sites for validation guidelines. Both ground and aerial field surveys were also conducted in this study by the Forest Fire Control Division, National Park, Wildlife and Plant Conversation Department, Ministry of Natural Resources and Environment, Thailand. High accuracy of 91.84 %, 95.60% and 97.53% for the 2007, 2008 and 2009 fire seasons were observed, resulting in increased confidence in the use of MODIS hotspots for forest fire control and management in Thailand.

    Full Text Available Abstract Background Knowledge, attitudes and practices of community members and healthcare providers in rural northern Ghana regarding clean delivery are not well understood. This study explores hand washing/use of gloves during delivery, delivering on a clean surface, sterile cord cutting, appropriate cord tying, proper cord care following delivery, and infant bathing and cleanliness. Methods In-depth interviews and focus group discussions were audiotaped, transcribed, and analyzed using NVivo 9.0. Results 253 respondents participated, including women with newborn infants, grandmothers, household and compound heads, community leaders, traditional birth attendants, and formally trained health care providers. There is widespread understanding of the need for clean delivery to reduce the risk of infection to both mothers and their babies during and shortly after delivery. Despite this understanding, the use of gloves during delivery and hand washing during and after delivery were mentioned infrequently. The need for a clean delivery surface was raised repeatedly, including explicit discussion of avoiding delivering in the dirt. Many activities to do with cord care involved non-sterile materials and practices: 1 Cord cutting was done with a variety of tools, and the most commonly used were razor blades or scissors; 2 Cord tying utilized a variety of materials, including string, rope, thread, twigs, and clamps; and 3 Cord care often involved applying traditional salves to the cord - including shea butter, ground shea nuts, local herbs, local oil, or “red earth sand.” Keeping babies and their surroundings clean was mentioned repeatedly as an important way to keep babies from falling ill. Conclusions This study suggests a widespread understanding in rural northern Ghana of the need for clean delivery. Nonetheless, many recommended clean delivery practices are ignored. Overarching themes emerging from this study included the increasing use of

    The shortage of community and hospital pharmacists is particularly acute in rural and remote areas of Australia. Pharmacy students, in particular, as those who may be able to alleviate this shortage, need to be made more aware of the challenges and rewards of rural pharmacy practice. A marketing tool was developed to promote rural and remote pharmacy practice as a career option. A DVD was produced from interviews with health professionals working in rural and remote areas of Australia. This DVD will complement current rural practical placements, which have been incorporated into the curriculum of Australian schools of pharmacy. Interviews were conducted with healthcare professionals from areas in Tasmania, Northern Queensland and the Northern Territory. Interviewees included pharmacists, graduate pharmacists, pharmacy students, aboriginal health workers and a general practitioner. Each of the interviewees was able to provide personal accounts of experiences in rural and remote healthcare, and roles and opportunities for pharmacists. A final draft of the DVD was shown to University of Tasmania students to assess the impact and quality of the production. A number of common themes arose from interviewing and these were subsequently converted into five key chapters of the DVD - Lifestyle, Belonging, Diversity, Indigenous Health and 'Give it a go'. The final DVD, produced from over 15 h of footage, runs for 35 min. Students reported positive feedback on both the technical quality and the information contained within the DVD; 37% of students who viewed the DVD felt that it increased their awareness of what rural pharmacy has to offer. The rural pharmacy, 'Enjoy the Lifestyle' DVD can be used to increase awareness of rural and remote pharmacy practice to students and other pharmacists, and complements other pharmacy workforce strategies for rural and remote areas of Australia. It could also be a useful approach for adaptation in other countries.

    Full Text Available Abstract Sixty one tissue samples from several rodent species trapped in five provinces of Thailand were examined for the presence of hantaviral markers by enzyme-immunoassay and immunoblotting. Four samples, all from the great bandicoot rat Bandicota indica, were confirmed positive for the hantaviral N-antigen. Two of them were trapped in Nakhon Pathom province, the other two in Nakhon Ratchasima province, approximately 250 km from the other trapping site. When analysed by RT-nested PCR, all four rodents were found positive for the hantaviral S- and M-segment nucleotide sequences. Genetic analysis revealed that the four newly described wild-type strains belong to Thailand hantavirus. On the phylogenetic trees they formed a well-supported cluster within the group of Murinae-associated hantaviruses and shared a recent common ancestor with Seoul virus.

    This is the first report of the large-scale utilization of migrants as health volunteers in a migrant primary-healthcare program. The program recruited migrants who volunteered to serve their communities. This study explores the identities of these volunteers, their relationship with program management, and their attitudes. The study also investigates the impact of the volunteers, from the migrants' and healthcare workers' perspective. The study was conducted in two provinces, Tak (northern Thailand) and Samut Sakhon (central Thailand). Primary and secondary information was collected. Mixed methods, comprising in-depth interviews, observation and questionnaires, were used to gather primary data from three groups of participants-migrant volunteers, migrants and healthcare workers. Secondary data, and in-depth interviews with healthcare workers, showed that migrant volunteers made a significant contribution to the provision of both preventive and curative services. The quantitative study covered 260 migrant volunteers and 446 migrants. The results found that <5% of volunteers were selected by the community. Almost all attended a training course. Most were assigned to be health communicators; four stated they did nothing. Volunteers' attitudes were very positive. Most migrants reported that the volunteers' work was useful. It was concluded that the migrant health-volunteer program did help deal with migrant health problems. However, management of the program should be closely considered for more effective outcomes.

    Abstract Objective To establish iodine status among pregnant women in rural northern Viet Nam and explore psychosocial predictors of the use of iodized salt in their households. Methods This prospective study included pregnant women registered in health stations in randomly-selected communes in Ha Nam province. At recruitment ( 28 weeks of gestation) a urine specimen was collected to measure urinary iodine concentration (UIC) and iodized salt use was assessed. Predictors were explored through univariable analyses and multivariable linear and logistic regression. Findings The 413 pregnant women who provided data for this study had a median UIC of 70 µg/l; nearly 83% had a UIC lower than the 150 µg/l recommended by the World Health Organization; only 73.6% reported using iodized salt in any form in their households. Iodized salt use was lower among nulliparous women (odds ratio, OR: 0.56; 95% confidence interval, CI: 0.32–0.96); less educated women (OR: 0.34; 95% CI: 0.16–0.71); factory workers or small-scale traders (OR: 0.52; 95% CI: 0.31–0.86), government workers (OR: 0.35; 95% CI: 0.13–0.89) and women with common mental disorders at recruitment (OR: 0.61; 95% CI: 0.38–0.98). Conclusion The decline in the use of iodized salt in Viet Nam since the National Iodine Deficiency Disorders Control Programme was suspended in 2005 has placed pregnant women and their infants in rural areas at risk of iodine deficiency disorders.

    There is ample documentation that use of hospital emergency facilities for reasons other than urgencies/emergencies results in clogged services in many urban centers. However, little has been published about similar misuse of emergency rooms/departments in rural and remote areas, where the situation is usually compounded by a scarcity of healthcare professionals. In Canada there is a shortage of physicians in rural and remote areas as a consequence of misdistribution (most physicians staying in southern urban centers after residence), and there is a chronic misuse of facilities meant for urgencies/emergencies to cope with primary healthcare needs. We address the problem in Elliot Lake, a rural Northern Ontario community of 12,000 people. The economy of Elliot Lake was based on uranium mining until the mid-1990s, when it drastically changed to become a center for affordable retirement and recreational tourism. As a consequence, at the present time the proportion of seniors in Elliot Lake doubles the Canadian average. Our objectives are to elucidate the demographics of emergency room (ER) clients and the effect of the elderly population; the nature of ER use; the perceived level of urgency of clients versus health professionals; and possible alternatives offered to non-urgent/emergency visits. This is the first study of the kind in Northern Ontario, a region the size of France. The study, conducted in July 2001, used a prospective survey, completed by patients and attending clinicians at the time of a patient's presentation to the ER of St Joseph's General Hospital. This hospital is staffed by family physicians, a nurse practitioner, and registered nurses (RNs). The catchment area population (town plus surrounding areas) of the hospital is approximately 18,000 people. ER clients were interviewed verbally, and the attending health professionals responded to written questionnaires. Demographics were recorded (age, sex, employment and marital status), as was each client

  16. Human rhinovirus infections in rural Thailand: epidemiological evidence for rhinovirus as both pathogen and bystander.

    Full Text Available BACKGROUND: We describe human rhinovirus (HRV detections in SaKaeo province, Thailand. METHODS: From September 1, 2003-August 31, 2005, we tested hospitalized patients with acute lower respiratory illness and outpatient controls without fever or respiratory symptoms for HRVs with polymerase chain reaction and molecularly-typed select HRVs. We compared HRV detection among hospitalized patients and controls and estimated enrollment adjusted incidence. RESULTS: HRVs were detected in 315 (16% of 1919 hospitalized patients and 27 (9.6% of 280 controls. Children had the highest frequency of HRV detections (hospitalized: <1 year: 29%, 1-4 year: 29%, ≥ 65 years: 9%; controls: <1 year: 24%, 1-4 year: 14%, ≥ 65 years: 2.8%. Enrollment adjusted hospitalized HRV detection rates were highest among persons aged <1 year (1038/100,000 persons/year, 1-4 years (457, and ≥ 65 years (71. All three HRV species were identified, HRV-A was the most common species in most age groups including children aged <1 year (61% and all adult age groups. HRV-C was the most common species in the 1-4 year (51% and 5-19 year age groups (54%. Compared to controls, hospitalized adults (≥ 19 years and children were more likely to have HRV detections (odds ratio [OR]: 4.8, 95% confidence interval [CI]: 1.5, 15.8; OR: 2.0, CI: 1.2, 3.3, respectively and hospitalized children were more likely to have HRV-A (OR 1.7, CI: 0.8, 3.5 or HVR-C (OR 2.7, CI: 1.2, 5.9 detection. CONCLUSIONS: HRV rates were high among hospitalized children and the elderly but asymptomatic children also had substantial HRV detection. HRV (all species, and HRV-A and HRV-C detections were epidemiologically-associated with hospitalized illness. Treatment or prevention modalities effective against HRV could reduce hospitalizations due to HRV in Thailand.

    Outbreaks of highly pathogenic avian influenza have occurred and have been studied in a variety of ecological systems. However, differences in the spatial resolution, geographical extent, units of analysis and risk factors examined in these studies prevent their quantitative comparison. This study aimed to develop a high-resolution, comparative study of a common set of agro-environmental determinants of avian influenza viruses (AIV) in domestic poultry in four different environments: (1) lower-Northern Thailand, where H5N1 circulated in 2004–2005, (2) the Red River Delta in Vietnam, where H5N1 is circulating widely, (3) the Vietnam highlands, where sporadic H5N1 outbreaks have occurred, and (4) the Lake Alaotra region in Madagascar, which features remarkable similarities with Asian agro-ecosystems and where low pathogenic avian influenza viruses have been found. We analyzed H5N1 outbreak data in Thailand in parallel with serological data collected on the H5 subtype in Vietnam and on low pathogenic AIV in Madagascar. Several agro-environmental covariates were examined: poultry densities, landscape dominated by rice cultivation, proximity to a water body or major road, and human population density. Relationships between covariates and AIV circulation were explored using spatial generalized linear models. We found that AIV prevalence was negatively associated with distance to the closest water body in the Red River Delta, Vietnam highlands and Madagascar. We also found a positive association between AIV and duck density in the Vietnam highlands and Thailand, and with rice landscapes in Thailand and Madagascar. Our findings confirm the important role of wetlands-rice-ducks ecosystems in the epidemiology of AI in diverse settings. Variables influencing circulation of the H5 subtype in Southeast Asia played a similar role for low pathogenic AIV in Madagascar, indicating that this area may be at risk if a highly virulent strain is introduced.

  18. Oligarchy in Thailand?

    Directory of Open Access Journals (Sweden)

    T. F. Rhoden

    2015-01-01

    Full Text Available A modern conception of oligarchy, which can be housed under an authoritarian regime as easily as it can under a liberal democratic one, can affect our understanding of the potential national political repercussions of extreme inequalities of wealth. This article has two goals: (1 to conceptually analyse the meaning of oligarchy; and (2 to make a descriptive case for its use in the Thai context. The test case of contemporary Thailand shows what exactly an oligarch or oligarchy means under a military regime and the potential effects for national politics of an oligarchy based on material wealth. Utilizing Jeffrey A. Winters’ Aristotelian-grounded conception of oligarchy for the contemporary world, this article argues that some political outcomes in Thailand are inexplicable without recourse to a modern variant of oligarchic theory and analysis.

  19. Thailand and brain drain

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Brain drain has been the subject of research since the 1960s. This research has been hampered by a lack of accurate data from both source and receiving countries on migration and on the losses and gains to developing economies of skilled migration. However, despite these handicaps, research has been able to clearly show that trends are changing and the effect this is having is usually quite different for individual source countries.Thailand, as a developing economy, could be regarded as a source country. Fortunately, Thailand has never ranked highly in terms of brain drain when compared to other states in Asia and while it may not be a significant problem it nonetheless needs to be monitored. Thailand is also somewhat unique in that the migration that has occurred has been almost equally split between secondary and tertiary educated Thais. Thailand also ranks low in terms of tertiary educated population who have migrated when compared to other countries in the region. Globalisation is having a profound effect on the migration of skilled workers. As trade becomes increasingly free, barriers to the movement of services or people are also freed. As the better educated are encouraged to think globally, so too will they be inclined to move globally into the world community.This paper examines Thailand’s position with respect to brain drain, some of the lessons we have learned and some of the steps that are being taken to minimise the impact of the loss of skilled workers, with a particular focus on science and technology. The conclusion is that brain drain should not be viewed as an entirely negative development and that the positive outcomes should be recognised, encouraged and incorporated into policy.

    Full Text Available Dengue is endemic to the rural province of Kamphaeng Phet, Northern Thailand. A decade of prospective cohort studies has provided important insights into the dengue viruses and their generated disease. However, as elsewhere, spatial dynamics of the pathogen remain poorly understood. In particular, the spatial scale of transmission and the scale of clustering are poorly characterized. This information is critical for effective deployment of spatially targeted interventions and for understanding the mechanisms that drive the dispersal of the virus.We geocoded the home locations of 4,768 confirmed dengue cases admitted to the main hospital in Kamphaeng Phet province between 1994 and 2008. We used the phi clustering statistic to characterize short-term spatial dependence between cases. Further, to see if clustering of cases led to similar temporal patterns of disease across villages, we calculated the correlation in the long-term epidemic curves between communities. We found that cases were 2.9 times (95% confidence interval 2.7-3.2 more likely to live in the same village and be infected within the same month than expected given the underlying spatial and temporal distribution of cases. This fell to 1.4 times (1.2-1.7 for individuals living in villages 1 km apart. Significant clustering was observed up to 5 km. We found a steadily decreasing trend in the correlation in epidemics curves by distance: communities separated by up to 5 km had a mean correlation of 0.28 falling to 0.16 for communities separated between 20 km and 25 km. A potential explanation for these patterns is a role for human movement in spreading the pathogen between communities. Gravity style models, which attempt to capture population movement, outperformed competing models in describing the observed correlations.There exists significant short-term clustering of cases within individual villages. Effective spatially and temporally targeted interventions deployed within villages may

    New and affordable point-of-care testing (POCT) solutions are hoped to guide antibiotic prescription and to help limit antimicrobial resistance (AMR)-especially in low- and middle-income countries where resource constraints often prevent extensive diagnostic testing. Anthropological and sociological research has illuminated the role and impact of rapid point-of-care malaria testing. This paper expands our knowledge about the social implications of non-malarial POCT, using the case study of a C-reactive-protein point-of-care testing (CRP POCT) clinical trial with febrile patients at primary-care-level health centres in Chiang Rai province, northern Thailand. We investigate the social role of CRP POCT through its interactions with (a) the healthcare workers who use it, (b) the patients whose routine care is affected by the test, and (c) the existing patient-health system linkages that might resonate or interfere with CRP POCT. We conduct a thematic analysis of data from 58 purposively sampled pre- and post-intervention patients and healthcare workers in August 2016 and May 2017. We find widespread positive attitudes towards the test among patients and healthcare workers. Patients' views are influenced by an understanding of CRP POCT as a comprehensive blood test that provides specific diagnosis and that corresponds to notions of good care. Healthcare workers use the test to support their negotiations with patients but also to legitimise ethical decisions in an increasingly restrictive antibiotic policy environment. We hypothesise that CRP POCT could entail greater patient adherence to recommended antibiotic treatment, but it could also encourage riskier health behaviour and entail potentially adverse equity implications for patients across generations and socioeconomic strata. Our empirical findings inform the clinical literature on increasingly propagated point-of-care biomarker tests to guide antibiotic prescriptions, and we contribute to the anthropological and

  4. Thailand's Missing Marine Fisheries Catch (1950–2014

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Overexploitation of marine resources has led to declining catches in many countries worldwide, and often also leads to fishing effort being exported to waters of neighboring countries or high seas areas. Thailand is currently under pressure to curb illegal fishing and human rights violations within its distant water fleets or face a European Union import ban. Simultaneously, Thailand is attempting to reduce fishing effort within its Exclusive Economic Zone (EEZ. Crucial to these endeavors is a comprehensive knowledge of total fisheries catches over time. A reconstruction of fisheries catches within Thailand's EEZ and by Thailand's fleet in neighboring countries' EEZs was undertaken for 1950–2014 to derive a comprehensive historical time series of total catches. This includes landings and discards that were not accounted for in official, reported statistics. Reconstructed Thai catches from within Thailand's EEZ increased from approximately 400,000 t·year−1 in 1950 to a peak of 2.6 million t·year−1 in 1987, before declining to around 1.7 million t·year−1 in 2014. Catches taken by Thai vessels outside their own EEZ increased from 52,000 t·year−1 in 1965 to a peak of 7.6 million t·year−1 in 1996, before declining to around 3.7 million t·year−1 by 2014. In total, reconstructed catches were estimated to be nearly three times larger than data reported by Thailand to the Food and Agriculture Organization of the United Nations (FAO. Reconstructed Thai distant-water fleet catches were almost seven times higher than the comparable non-domestic catch deemed reported for Thailand. Thai landings from recreational fishing were conservatively estimated for the first time, and while they contributed less than 1% of current catch, they can be expected to grow in volume and importance with increasing tourism. As Thailand takes measures to reduce fishing effort within its EEZs and increases monitoring and enforcement of illegal and foreign

  6. Bangkok as a magnet for rural labour: changing conditions, 1900-1970.

    Ouyyanont, P

    1998-06-01

    This article describes labor force shifts, in Thailand, from rural areas to Bangkok during 1900-1970 and is a revision of a chapter from a doctoral thesis. Urban growth of Bangkok occurred primarily after World War II. Pre-war wages in rural areas were higher than coolie wages in Bangkok. Opportunity costs of changing occupations were high. Chinese immigration was the key to development of non-farm occupations. The Chinese from Siam were drawn to higher wages in Bangkok than were possible in South China ports. After the war, the Lewis-Fei and Ranis migration model fits a pattern of migration that adjusts the disequilibrium between urban and rural markets. There are shifts from low productivity rural sectors to urban high productivity sectors. Capital investment in commerce and industry raised urban labor productivity. The wage data suggest a growing gap between urban and rural sectors postwar. Rail travel during the 1950s brought higher wages for the unskilled in railroad construction. There was high agricultural productivity relative to labor input due to availability of land. Underpopulation meant little unemployment. After 1950, conditions changed. The population growth rate increased. More in rural areas lived below the poverty line. Low rice productivity constrained rural wages and incomes during the 1950s and 1960s. The more favored commercial crops needed less labor. Chinese immigration declined, and demand for labor increased in urban areas. Low urban wages due to cheap labor stimulated profits and growth. Major roads connected Bangkok to the south and the north. Bangkok was viewed as a magical and desirable place.

    Chronic pain remains prevalent in HIV+ adults despite widespread antiretroviral use. Pain continues to be underrecognized and undertreated in this population. In Thailand, similar to the West, HIV care is transitioning toward chronic disease management. Despite the importance of pain management in chronic HIV, the prevalence of pain and adequacy of pain management is unknown in HIV+ adults in Thailand. This cross-sectional study aimed to determine the prevalence of chronic pain, the burden of inadequate analgesia, and risk factors for chronic pain in HIV+ adults in Thailand. A total of 254 HIV+ adults were recruited from an outpatient clinic in Thailand. Interviewers obtained information on demographics, clinical data, and pain characteristics. The burden of inadequate analgesia was assessed using the Brief Pain Inventory. Risk factors were identified with logistic regression analysis. Frequent pain was reported by 27% of participants; 22% reported chronic pain. Pain was significantly associated with education less than primary school, a positive depression screen, and the number of years on combined antiretroviral therapy. Eighty-six percent of patients with frequent pain were inadequately treated. Of 34 patients with moderate or severe pain, none received adequate analgesia. Inadequate analgesia was a significant risk factor for poorer quality of life. Despite widespread antiretroviral use, pain remains common and undertreated in HIV+ adults in Thailand. Undertreated pain negatively impacts quality of life. It is imperative that policy makers and HIV caregivers address this treatment gap to advance the care of people living with HIV in Thailand.

    2017-09-26

    Due to rapid urbanization, solid waste management (SWM) has become a significant issue in several developing countries including Thailand. Policies implemented by the Central Thai Government to manage SWM issues have had only limited success. This article reviews current municipal waste management plans in Thailand and examines municipal waste management at the local level, with focus on the Tha Khon Yang sub-district surrounding Mahasarakham University in Mahasarakham Province. Within two decades this area has been converted from a rural to an urban landscape featuring accommodation for over 45,000 university students and a range of business facilities. This development and influx of people has outpaced the government's ability to manage municipal solid waste (MSW). There are significant opportunities to improve local infrastructure and operational capacity; but there are few mechanisms to provide and distribute information to improve community participation in waste management. Many community-based waste management projects, such as waste recycling banks, the 3Rs (reduce, reuse and recycle), and waste-to-biogas projects have been abandoned. Additionally, waste from Tha Kon Yang and its surrounding areas has been transferred to unsanitary landfills; there is also haphazard dumping and uncontrolled burning of waste, which exacerbate current pollution issues.

    Clostridium difficile is the aetiological agent in ca. 20% of cases of antimicrobial-associated diarrhoea in hospitalised adults. Diseases caused by this organism range from mild diarrhoea to occasional fatal pseudomembranous colitis. The epidemiology of C. difficile infection (CDI) has changed notably in the past decade, following epidemics in the early 2000s of PCR ribotype (RT) 027 infection in North America and Europe, where there was an increase in disease severity and mortality. Another major event has been the emergence of RT 078, initially as the predominant ribotype in production animals in the USA and Europe, and then in humans in Europe. Although there have been numerous investigations of the epidemiology of CDI in North America and Europe, limited studies have been undertaken elsewhere, particularly in Asia. Antimicrobial exposure remains the major risk factor for CDI. Given the high prevalence of indiscriminate and inappropriate use of antimicrobials in Asia, it is conceivable that CDI is relatively common among humans and animals. This review describes the level of knowledge in Thailand regarding C. difficile detection methods, prevalence and antimicrobial susceptibility profile, as well as the clinical features of, treatment options for and outcomes of the disease. In addition, antimicrobial usage in livestock in Thailand will be reviewed. A literature search yielded 18 studies mentioning C. difficile in Thailand, a greater number than from any other Asian country. It is possible that the situation in Thailand in relation to CDI may mirror the situation in other developing Asians countries.

    The rural innovation research and development (R and D) in beef cattle genetics, biotechnology, climate science and production systems, supported profitable and sustainable beef cattle production in Thailand. Department of Livestock Development (DLD) undertakes R and D to achieve continuous improvement in genetics, production technologies to improve productivity, profitability and sustainability of beef cattle production and quality of products. Efficiencies were achieved through improvements in genetics, nutrition and grazing management, use of information, meat science, and reduction in ruminant methane production. This function was essential to maintain long-term production competitiveness and achieve sustained economic growth in rural Thailand, where the beef cattle production was the important livestock production, accounting for 36.99% of the value of livestock production in Thailand. Molecular, quantitative genetics, and biotechnology tool were being combined in the development of genetic improvement. In 2006, beef meat was imported 1,842.53 thousand tons (0.41% of all consumption, 120.84 baht/kg). For the big size cattle, such as Tak cattle, Kabinburi cattle (Thai synthetic breeds by DLD, Tak = 62.5 Charoles-Brahman, Kabinburi = 50 Simental- Brahman), and cross breed cattle, they were in fattening period for 6-12 month. Fattening group, they were raised for restaurant, hotel, super market, and steak house. Data were collected from 2 parts: 1) 354 cattle of experimental trial in DLD part, and 2) 492 fattening cattle of small holders in Tak province and Nakorn Pathom province during October 2004-September 2007. Data collecting was separated into 2 parts (performance data and reference). Data were adjusted by group location month and year to analyze for growth, carcass performance and economic performances). There were 5 breeds of fattening beef cattle: 1) Thai Native, 2) Thai Brahman, 3) Kabinburi, 4) Tak, and 5) Tajima-Native. The first group was around 41

    Women in Viet Nam have long had to face various sexual and reproductive health problems, ranging from abortion to reproductive tract infections (RTIs) and sexual coercion. These issues have increasingly been addressed by scholars in the fields of public health and social sciences through sexual and reproductive health research and in other ways. Despite this, there remains a lack of in-depth information on attitudes and practices regarding sex and sexuality of Vietnamese women today. This paper in part responds to the knowledge gap by reporting on findings from qualitative research on sexual attitudes and practices among rural married women in a Northern rural community, measured against the broader social and cultural context. Twenty-five women in total were interviewed; and two focus group discussions were conducted. The findings show that women generally believe that men are (or should be) the initiators in sexual relations. Many women feel reluctant to refuse sex to their husbands or communicate openly about sex and sexuality. However, this paper also demonstrates that women are not totally passive in sexual relations. Women in this study used a range of strategies to negotiate their sexual life, and sometimes 'silence' is used as a form of agency in order to maintain harmony and happiness within the family.

    The aim of this study was to evaluate changes to, and predictors of, quality of life (QOL) in a community-based cohort of stroke survivors from an earlier stroke incidence study in rural northern Tanzania. Patients were assessed 1-5 years after their incident stroke. The study cohort was compared with an age- and sex-matched control group from the same rural district within a cross-sectional design. Patients and controls were asked a series of questions relating to their QOL [World Health Organization quality of life, abbreviated version (WHOQOL-BREF)], levels of anxiety and depression [hospital anxiety and depression (HAD) scale], cognitive function [community screening instrument for dementia (CSI-D) screening tool], socioeconomic status and demographic characteristics (e.g. age, sex, education and abode). Patients were further assessed for functional outcome and disability (Barthel index, modified Rankin scale), post-stroke care and psychosocial functioning. Patients (n = 58) were found to have significantly lower QOL than controls (n = 58) in all six domains of the WHOQOL-BREF. Gender, socioeconomic status, cognitive function and time elapsed since stroke were not associated with QOL. Older patients and those with more impaired motor function and disability (Barthel index, modified Rankin score) had significantly poorer physical health-related QOL. Greater anxiety and depression, reduced muscle power and less involvement in social events were significantly correlated with lower physical and psychological health-related QOL. To our knowledge, this is the first long-term study of QOL in survivors of incident stroke in Sub-Saharan Africa (SSA). Poorer QOL was associated with greater levels of physical disability, anxiety and depression and reduced social interaction. Demographic factors appear to be much less significant. Modifying these QOL predictors could be important in planning effective post-stroke care within a stretched healthcare system.

    Recent years have seen the greatest ecological disturbances of our times, with global human expansion, species and habitat loss, climate change, and the emergence of new and previously-known infectious diseases. Biodiversity loss affects infectious disease risk by disrupting normal relationships between hosts and pathogens. Mosquito-borne pathogens respond to changing dynamics on multiple transmission levels and appear to increase in disturbed systems, yet current knowledge of mosquito diversity and the relative abundance of vectors as a function of habitat change is limited. We characterize mosquito communities across habitats with differing levels of anthropogenic ecological disturbance in central Thailand. During the 2008 rainy season, adult mosquito collections from 24 sites, representing 6 habitat types ranging from forest to urban, yielded 62,126 intact female mosquitoes (83,325 total mosquitoes) that were assigned to 109 taxa. Female mosquito abundance was highest in rice fields and lowest in forests. Diversity indices and rarefied species richness estimates indicate the mosquito fauna was more diverse in rural and less diverse in rice field habitats, while extrapolated estimates of true richness (Chao1 and ACE) indicated higher diversity in the forest and fragmented forest habitats and lower diversity in the urban. Culex sp. (Vishnui subgroup) was the most common taxon found overall and the most frequent in fragmented forest, rice field, rural, and suburban habitats. The distributions of species of medical importance differed significantly across habitat types and were always lowest in the intact, forest habitat. The relative abundance of key vector species, Aedes aegypti and Culex quinquefasciatus, was negatively correlated with diversity, suggesting that direct species interactions and/or habitat-mediated factors differentially affecting invasive disease vectors may be important mechanisms linking biodiversity loss to human health. Our results are an

    Thailand has started the peaceful utilization of nuclear program in 1961. The program has developed considerably in various aspects. Laws and regulations were established while applications in medical, agriculture, industry as well as research and education have been accomplished successfully in the country. As for the energy production, Thailand has realized the importance of nuclear power generation several years back. However, the implementation has been delayed. There are four main nuclear organizations namely The Thai Atomic Energy Commission - the country's policy holder, the Office of Atoms for Peace (OAP) - the nuclear regulatory bodies, Thailand Institute of Nuclear Technology (TINT: Public Organization) - the research and services provider in nuclear field and the Nuclear Society of Thailand the non-governmental organization. Major research in nuclear technology is actively carried out at TINT. Filed of research include medical and public health, agricultural, material and industrial, environmental and advanced technology like neutron scattering and nuclear fusion. Nuclear density gauge has been utilized in many industries including petrochemical production and refineries. TINT is also providing services on nuclear radiography to industrial and clients. Additionally, x-ray techniques have been utilized in many manufacturers for quality and process control. Nuclear applications for medical purpose have been utilized in Thailand several years back both for diagnostic and therapeutic purposes. To ensure safe and peaceful use of nuclear technology and for the safety of the general public in Thailand, OAP has launched laws, regulations and ministerial announcements. Thailand has only one multi-purposes nuclear research reactor and no NPP. Yet we have realized the importance of nuclear power generation several years back. (N.T.)

    Child prostitution is an old, global and complex phenomenon, which deprives children of their childhood, human rights and dignity. Child prostitution can be seen as the commercial sexual exploitation of children involving an element of forced labour, and thus can be considered as a contemporary form of slavery. Globally, child prostitution is reported to be a common problem in Central and South America and Asia. Of all the south-east Asian nations, the problem is most prolific in Thailand. In Thailand, there appears to be a long history of child prostitution, and this article explores the factors that underpin the Thai child sex industry and the lessons and implications that can be drawn for health care and nursing around the world.

    Dengue is the most frequent arboviral disease and is expanding geographically. Dengue is also increasingly being reported in travellers, in particular in travellers to Thailand. However, data to quantify the risk of travellers acquiring dengue when travelling to Thailand are lacking. Using mathematical modelling, we set out to estimate the risk of non-immune persons acquiring dengue when travelling to Thailand. The model is deterministic with stochastic parameters and assumes a Poisson distribution for the mosquitoes' biting rate and a Gamma distribution for the probability of acquiring dengue from an infected mosquito. From the force of infection we calculated the risk of dengue acquisition for travellers to Thailand arriving in a typical year (averaged over a 17-year period) in the high season of transmission. A traveller arriving in the high season of transmission and remaining for 7 days has a risk of acquiring dengue of 0·2% (95% CI 0·16-0·23), whereas the risk for travel of 15 and 30 days' duration is 0·46% (95% CI 0·41-0·50) and 0·81% (95% CI 0·76-0·87), respectively. Our data highlight that the risk of non-immune travellers acquiring dengue in Thailand is substantial. The incidence of 0·81% after a 1-month stay is similar to that reported in prospective seroconversion studies in Israeli travellers to Thailand, highlighting that our models are consistent with actual data. Risk estimates based on mathematical modelling offer more detailed information depending on various travel scenarios, and will help the travel medicine provider give better evidence-based advice for travellers to dengue-endemic countries.

    At present, construction of rural domestic waste treatment facilities is seriously lagging, and in many cases, treatment facilities do not yet exist in some villages of China. Serious rural waste pollution has not only impacted the quality of surface water and groundwater but also the atmosphere and the living environment of farmers of China. There are relatively few studies of rural domestic waste pollution, especially with respect to the spatio-temporal dynamic pattern of rural domestic waste discharge. Using survey data and income per capita, we calculated rural domestic waste discharge per capita per day. From this, we calculated provincial rural domestic waste discharge. According to our study, rural domestic waste discharge was 1.42 × 10 8 t/year in 2000. This number increased to 2.3 × 10 8 t/year in 2006 and to 2.47 × 10 8 t/year in 2010. Rural domestic waste increased dramatically while the actual rural population and the proportion of the rural population declined. When examining the eight regions, the rural domestic waste discharge of northeastern China, Qinghai-Tibet, middle China, and southwestern China had increased dramatically, while that of northern China, southern China, and eastern China increased relatively slowly. The economies of northern China, southern China, and eastern China are more developed; their rural domestic waste discharge has been high since 2000 and has continued to increase slowly. In northeastern China, Qinghai-Tibet, middle China, and southwestern China, rural domestic waste discharge was low in 2000; however, in the ten-year period from 2000 to 2010, their rural domestic waste discharge increased dramatically.

    Study the incidence of drug abuse in persons with unnatural deaths such as traffic accidents, homicide with gunshot wounds, etc. One hundred and fifty three cases with a mean age of 34 years (range 10 to 76) were studied. The decedents were mostly male (92%), with a variety of occupations including laborers (76.9%), traders (15.4%), and student (7.7%). The causes of death were mainly traffic injuries (33%), gunshot wounds (26%) and others (stab wound, poisoning, asphyxia etc 41%). The manner of death was accidents in 40% and homicides in 28%. Nine percent were positive for methamphetamine or amphetamine derivatives. Tests for Heroin, 6-MAM, morphine, or cocaine were also performed but not detected. The drug positive cases were mostly males (85%) with the most common age range of 21-30 years (35.4%) and 61% with only primary education. Homicide by gunshot wounds was the most common cause of death at 69.2%, followed by hanging (15.4%), electrocution (7.7%), and poisoning (7.7%). The concentration of methamphetamine in urine was between 501-61,147 ng/ml, which cannot be correlated with intoxication. There were no deaths from overdose. Three Benzodiazepine, one toluene, and one meperidine cases were also found in cases of methamphetamine abuse. Alcohol was found mostly in the persons with unnatural deaths (53.6%) from traffic accidents. This information helps us understand the marketing strategies, and the trading routes. All data will be used for planning to eradicate these drugs from Thailand in line with government strategies.

    Previous studies among Buddhist monks in Thailand have reported smoking rates to be as high as 55%. Because 95% of Thais are Buddhist, monks are highly influential in establishing normative behavioral patterns. As the first population-based study on smoking among Buddhist monks in Thailand, this study aims to determine the smoking prevalence in six regions of the country, and to examine smoking knowledge, risk perceptions, behaviors, and associated demographics among full-fledged and novice monks (n = 6,213). Results demonstrated that the overall prevalence for current smoking monks is 24.4% (95% confidence interval [24.453, 24.464]), with regional differences ranging from 14.6% (North) to 40.5% (East). Findings suggest that integrating prevention and cessation programming into religious courses may be one avenue for reaching many incoming monks. Further, involving monks in tobacco control education and setting a nonsmoking standard among them is vital to the success of reducing smoking rates among the general population in Thailand.

    A parasitological investigation on trematode metacercariae was made on 62 freshwater fishes of 13 species in northern Thailand; Cyclocheilichthys apogon, Puntioplites proctozysron, Labiobarbus siamensis, Barbodes gonionotus, Barbodes altus, Henicorhynchus siamensis, Osteochilus hasselti, Notopterus notopterus, Mystacoleucus marginatus, Anabas testudineus, Systomus orphoides, Morulius chrysophykadian, and Hampala macrolepidota. The fish were caught over the summer period (February-May 2007) from 2 Chiang Mai water reservoirs, i.e., the Mae Ngad (UTM 47Q E 503200, 47Q N 2119300) and the Mae Kuang Udomtara (UTM 47Q E 513000, 47Q N 2092600) Reservoirs in Chiang Mai province, Thailand. The prevalence of heterophyid (Haplorchis taichui and Haplorchoides sp.) metacercariae in these fish was 83.9% and 74.2% in the Mae Ngad and Mae Kuang Udomtara Reservoirs, respectively. The highest intensity of heterophyid metacercariae in H. siamensis in the Mae Ngad was 120.4 and that in P. proctozysron in the Mae Kuang Udomtara was 180.0. The fish, A. testudineus, C. apogon, and M. chrysophykadian, were not found to be infected with H. taichui metacercariae. The results show that the freshwater fish in Chiang Mai water reservoirs are heavily infected with H. taichui and Haplorchoides sp. metacercariae. PMID:18552549

    Full Text Available Thailand 4.0 is a new ‘buzzword’ for many things just now being defined. It also appears to mean many things to many people, but the majority of Thai citizens surveyed fail to grasp just what it is. In the simplest of terms, it seems to be a Thai government policy in which technology and innovation are proposed tools for boosting the quality of life. Thailand 4.0 is also targeted at 10 key economic sectors and their supporting research from US$1 billion in funding for 12,290 new PhDs. This research, therefore, investigated the legacy of proceeding Thailand 1.0, 2.0, and 3.0, the use of the S-curve to describe their implementations, educational objectives to support Thailand 4.0, the digital/e-commerce agenda, agribusiness and ‘smart farmers’, how to learn from unicorns, and what is meant by ‘next generation automotive’ under Thailand 4.0.

    Traditional healers (mor baan) played an important role in Thai health long before the introduction of Western medicine. Although modern health professional play a key role of health care provider of Thai health care system, traditional healers and their practice still exist in most rural areas of Thailand. In this article, we address the roles and practices of traditional healers in southern Thailand. An ethnographic method was employed. This approach is the hallmark method used to describe the role and the practice of traditional healers and to grasp in-depth understanding of their everyday life. Participation observation and unstructured interview with 18 traditional healers were conducted. Thematic analysis method was used to analyse the data. Most of the traditional healers chose their role because they were influenced by their ancestors, although a few others chose it because of individual interests and a desire to help ill people. All are trained in multiple skills, using supernatural spirits, ceremonies and natural plant products as resources for counteracting various health problems. They refer patients to modern hospitals or other healers if they cannot adequately manage illness themselves. Their service provision is flexible and based on a holistic approach that suits people's lifestyles and needs. The role of traditional healer tends not to attract the interest of younger generations, although traditional healers have contributed greatly to people's health. Their presence improves people's access to healthcare and offers an alternative to modern medicine, which often has a limited role. We conclude that the services of traditional healers should be incorporated into contemporary healthcare provision of Thai health care system.

    The major nuclear facilities in Thailand are composed of nuclear research reactor, neutron generators, electron linear accelerators and 1 GeV Synchrotron facility, which is under construction. The other small facilities are radioisotope sources and X ray tubes for X ray diffraction and fluorescence studies. Office of Atomic Energy for Peace (OAEP) is the function arm for nuclear institutions in Thailand. Its major roles are nuclear regulatory, coordinating for nuclear affairs and foreign relations, R and D for nuclear science and technology and giving nuclear services. Nuclear data activities concerning Thai Research Reactor (TRR-1/M1) are for examples: neutronics and thermalhydraulics for reactor operation, neutron energy spectrum and neutron flux measurement for neutron activation analysis and isotope production, neutron and gamma doses, shielding and material testing for radiation safety, and neutron beam experiments. OAEP is taking part in the areas of regional cooperation on utilization of nuclear research reactors, education and training, sharing of research reactor experimental facilities, establishment of nuclear data program and information exchange. The nuclear data reports have been shared among institutions in Thailand through OAEP, which is served as a central nuclear data depository including e.g., INIS, IAEA-NDS, Joint Research Centre Commission of the European Communities and Japanese Nuclear Data Committee (JNDC). This report shows the nuclear facilities in Thailand, the roles of the Office of Atomic Energy for Peace on nuclear data depository and nuclear power development program. The main activities at the Thai Research Reactor TRR-1/M1 concerning nuclear data needs for specific uses in both theoretical and experimental aspects are also described. (J.P.N.)

    Full Text Available South Korea and Thailand which are receiving the financial support from IMF got similar international remarks on promoting the economic reform that has an exemplary effect. However, there are not only differences in the causes of the economic crisis, but also the status and effect of the economic reform. At present, Thailand gets a more ascendant status than South Korea in the "quo" status of attracting foreign investment. The reason is that the causes of the economic crisis in Thailand are relatively simple and the process of economic reform is also simple. Besides, Thailand is in the condition which made the effect came true easy. Meanwhile, since the procedures of firing the staff in Thailand are cut off, and the employees are easy to lose their jobs, it insures the flexibility of the labor market. Besides, the Thai government reduces the investment risk of foreigners by way of investing in stocks of the same value or remaining guarantee. South Korea also should insure the flexibility of the labor market and promote the flexibility of attracting foreign investment, which bases on the cooperation of the workers, employees and the government. If transfers the ill creditor’s rights to large bank, foreign investors should be encouraged by permitting an alternative of receiving the good asset or government warranty.

  12. A review of Thailand's strategies for global climate change

    Thailand is greatly concerned about global climate change, which is caused primarily by the burning of fossil fuels, deforestation and the release of chlorofluorocarbons. The country itself is not currently a major contributor to global climate change. However, as Thailand's economy expands and its burning of fossil fuels increases, the country's contribution to global climate change could increase. Thailand's use of primary energy supplies grew at an average rate of 13.4 percent per year in the period 1985 to 1990. The rapid, sustained growth was due to the overall pace of growth in the economy and the expansion of industrial, construction, and transportation activities. The primary energy demand was approximately 31,600 kilotons of oil equivalent (KTOE) in 1990. The transportation sector accounted for the largest proportion of energy demand at 30 percent. Within the next 15 years, the power sector is expected to overtake the transportation sector as the largest consumer of energy. Petroleum is currently the predominant source of energy in Thailand, accounting for 56 percent of the primary energy demand. Thailand recognizes that it has an important part to play in finding solutions to minimizing emissions of greenhouse gases and identifying viable response strategies. Thus, in this paper the authors will present several policy strategies relevant to climate change in Thailand and discuss how they have been implemented and enforced. Policies concerning forestry, energy, and environment are reviewed in detail in this paper

    The radioelement concentration in the natural environment as well as the radiation exposure to man in day-to-day life is now the most interesting topic. The natural radiation is frequently referred as a standard for comparing additional sources of man-made radiation such as atomic weapon fallout, nuclear power generation, radioactive waste disposal, etc. The Department of Mineral Resources commenced a five-year project of nationwide airborne geophysical survey by awarding to Kenting Earth Sciences International Limited in 1984. The original purpose of survey was to support mineral exploration and geological mapping. Subsequently, the data quantity has been proved to be suitable for natural radiation information. In 1993 the Department of Mineral Resources, with the assistance of IAEA, published a Background Radiation Map of Thailand at the scale of 1:1,000,000 from the existing airborne radiometric digital data. The production of Background Radiation Map of Thailand is the result of data compilation and correction procedure developed over the Canadian Shield. This end product will be used as a base map in environmental application not only for Thailand but also Southeast Asia region. (author)

    Nipah virus (NiV) first emerged in Malaysia in 1998, with two bat species (Pteropus hypomelanus and P. vampyrus) as the putative natural reservoirs. In 2002, NiV IgG antibodies were detected in these species from Thailand, but viral RNA could not be detected for strain characterization. Two strains of NiV (Malaysia and Bangladesh) have been found in P. lylei in central Thailand, although Bangladesh strain, the causative strain for the outbreak in Bangladesh since 2001, was dominant. To understand the diversity of NiV in Thailand, this study identified NiV strain, using molecular characterizations, from P. hypomelanus in southern Thailand. Pooled bat urine specimens were collected from plastic sheet underneath bat roosts in April 2010, and then monthly from December 2010 to May 2011 at an island in southern Thailand. Five in 184 specimens were positive for NiV, using duplex nested RT-PCR assay on partial nucleocapsid fragment (357 bp). Whole sequences of nucleocapsid gene from four bats were characterized. All 5 partial fragments and 4 whole nucleocapsid genes formed a monophyletic with NiV-MY. Our study showed that P. hypomelanus in southern Thailand and from Malaysia, a bordering country, harbored similar NiV. This finding indicates that NiV is not limited to central Thailand or P. lylei species, and it may be a source of inter-species transmission. This indicates a higher potential for a widespread NiV outbreak in Thailand. NiV surveillance in Pteropus bats, the major natural reservoirs, should be conducted continuously in countries or regions with high susceptibility to outbreaks.

    In Thailand, total drug expenditure has grown rapidly. Recently, the Thai government has addressed the issue of drug pricing, but the prices of single-source drugs remain a major challenge. To examine equitable prices of single-source drugs in Thailand. A total of 98 single-source and high-expenditure drugs were examined. Unit prices from the Drug and Medical Supplies Information Center (DMSIC) and National Average Drug Acquisition Cost (NADAC) were used to represent drug prices at the provider level in Thailand and the U.S., respectively. Data for measuring drug affordability, e.g., dose and poverty line, were obtained from Micromedex online and the National Statistical Office (NSO). The U.S. drug prices were adjusted by the Human Development Index (HDI) to be equitable prices for Thailand. Purchasing Power Parity (PPP) was used to convert US currency into Thai baht. All prices in this study were based on the year 2012. Catastrophic, Impoverishment, and WHO/Health Action International (HAI) approaches were used to determine Thai citizens' ability to afford the study drugs. Finally, uncertainty analyses were conducted. From all study drugs, 55 single-source drugs were priced higher than their equitable prices, ranging from 0.38 to 422.36% higher. Among these, 28 items were antineoplastic drugs. The prices of drugs outside the National List of Essential Medicines (NLEM), as well as the country's newer drugs, tended to be higher than their calculated equitable prices. The majority of drugs in Thailand priced higher than equitable prices were unaffordable for most Thai citizens. The uncertainty analyses revealed that almost all results were relatively robust. Most single-source drug prices in Thailand were higher than their equitable prices, and were likely to be unaffordable to Thai citizens.

    Polymethoxylated flavones (PMFs) and flavanone glycosides (FGs) were analyzed in hand-pressed juice and the peeled fruit of 'Sainampueng' tangerines ( Citrus reticulata Blanco cv. Sainampueng) grown in northern Thailand. The tangerines were collected from a citrus cluster of small orchard farmers and were cultivated as either agrochemical-based (AB), agrochemical-safe (AS), or organic grown fruits. Juice samples were also measured on contents of carotenoids, ascorbic acid, and tocopherols. The peel-deriving PMFs tangeretin, nobiletin, and sinensetin were found with high concentrations in juice as a result of simple squeezing, whereas amounts of those PMFs were negligibly low in peeled tangerine fruit. In contrast, the mean concentrations of the FGs narirutin, hesperidin, and didymin were several fold higher in peeled fruit than in tangerine juice and significantly higher in organic than AS and AB tangerines. Narirutin and hesperidin in juice from organic produces as well as narirutin in juice from AS produces were significantly higher than respective mean concentrations in juice from AB produces. beta-Cryptroxanthin was the predominant carotenoid beside zeaxanthin, lutein, lycopene, and beta-carotene in tangerine juice. Ascorbic acid concentrations were not predicted by the type of cultivation, whereas alpha-tocopherol was significantly higher in juice from organic than AS produces. In summary, hand-pressed juice of C. reticulata Blanco cv. Sainampueng serves as a rich source of PMFs, FGs, carotenoids, and antioxidants: 4-5 tangerine fruits ( approximately 80 g of each fruit) giving one glass of 200 mL hand-pressed juice would provide more than 5 mg of nobiletin and tangeretin and 36 mg of hesperidin, narirutin, and didymin, as well as 30 mg of ascorbic acid, >1 mg of provitamin A active beta-cryptoxanthin, and 200 microg of alpha-tocopherol.

    Dengue fever is one of the important causes of illness among travelers returning from Thailand. The risk of infection depends on the length of stay, activities, and arrival time. Due to globalization, there is a concern that infected travelers may carry dengue virus (DENV) to their country of residence and cause an outbreak. To estimate the infective person-days of travelers returning from Thailand, we developed a model with the following parameters: the probability of travelers being infected, number of arrivals, length of stay of travelers, incubation period, and duration of the infective period. The data used in this study were the dengue incidences in Thailand during 2004-2013 and foreign traveler arrivals in 2013. We estimated the highest infective person-days for each country group. The highest value was from June to August during the rainy season in Thailand for all groups. Infective person-days ranged from 87 to 112 per 100,000 travelers each year. Our results provided a fundamental step toward estimation of the risk of the secondary transmission of DENV in non-epidemic countries via travelers, which can serve as an early warning of a dengue outbreak. The highest infective person-day is associated with the rainy season in Thailand. The increasing number of overseas travelers may increase the risk of global transmission of the DENV. Better understanding of the virus transmission dynamics will enable further quantitative predictions of epidemic risk. © 2015 International Society of Travel Medicine.

    Transnational food retailers expanded to middle-income countries over recent decades responding to supply (liberalized foreign investment) and demand (rising incomes, urbanization, female workforce participation, and time poverty). Control in new markets diffuses along three axes: socio-economic (rich to poor), geographic (urban to rural), and product category (processed foods to fresh foods). We used a mixed method approach to study the progression of modern retail in Thailand on these three axes and consumer preferences for food retailing. In Thailand modern retail controls half the food sales but traditional fresh markets remain important. Quantitative questionnaires administered to members of a large national cohort study revealed around half of respondents were primarily traditional shoppers and half either utilized modern and traditional formats equally or primarily shopped at supermarkets. Fresh foods were mainly purchased at traditional retail formats and dry packaged foods at supermarkets. Qualitative interviews found price and quality of produce and availability of culturally important products to be significant reasons for continued support of fresh markets. Our results show socio-economic and geographic diffusion is already advanced with most respondents having access to and utilizing modern retail. Control of the fresh food sector by transnationals faces barriers in Thailand and may remain elusive. The short to mid-term outcome may be a bifurcated food system with modern and traditional retail each retaining market share, but fresh markets longer term survival may require government assistance as supermarkets become more established. Fresh markets supply affordable, healthy foods, and livelihoods for poorer Thais and are repositories of Thai food culture and social networks. If they survive they will confer cultural, social, economic, and health benefits.

    Full Text Available Although Vietnamese have been migrating to Thailand for many centuries, the situationwhich they faced in terms of living and working changed significantly in 1945. This resulted from theattempt by the French to recolonise the Indochina region, which led to many Vietnamese seeking toflee the fighting and oppression by moving to Thailand. The experiences of this generation of peopleand their activities in the labour market are the main focus of this paper. It is shown that thisgeneration of Yuon Op Pha Yop represents a unique set of people in Thailand. Their experiences areset against the labour market experiences of other sets of Vietnamese migrants in Thailand.

    Full Text Available Avian influenza virus subtype H5N1 is endemic to Southeast Asia. In Thailand, avian influenza viruses continue to cause large poultry stock losses. The spread of the disease has a serious impact on poultry production especially among rural households with backyard chickens. The movements and activities of chicken traders result in the spread of the disease through traditional trade networks. In this study, we investigate the dynamics of avian influenza in the traditional trade network in Phitsanulok Province, Thailand. We also propose an individual-based model with intervention strategies to control the spread of the disease. We found that the dynamics of the disease mainly depend on the transmission probability and the virus inactivation period. This study also illustrates the appropriate virus disinfection period and the target for intervention strategies on traditional trade network. The results suggest that good hygiene and cleanliness among household traders and trader of trader areas and ensuring that any equipment used is clean can lead to a decrease in transmission and final epidemic size. These results may be useful to epidemiologists, researchers, and relevant authorities in understanding the spread of avian influenza through traditional trade networks.

    The analytical research studied representation of Thailand in travel writings in English through a stylistic approach, discourse analysis, and conceptions of Orientalism. It found that the writings provide a socio-cultural overview of Thailand and details of tourist attractions. The otherness of “Thainess” is constructed through Thailand's exotic beauty, dangers, social problems, political instability, inadequate freedom of expression, and ‘other habitus’ of Thais. These conceptualizations construct the readers' or tourists' identities as quality travelers and highly knowledgeable and moral individuals.

    As part of a broader medical and psychosocial needs assessment in a rural region of northern California, USA, five focus groups were conducted to explore innovative approaches to creating a system of consumer involvement in the delivery of HIV primary care services in the region. A total of five focus groups (n = 30) were conducted with clients from three of five counties in the region with the highest number of HIV patients receiving primary care. Participants were recruited by their HIV case managers. They were adults living with HIV, who were receiving health care, and who resided in a rural mountain region of northern California. Group discussions explored ideas for new strategies and examined traditional methods of consumer involvement, considering ways they could be adapted for a rural environment. Recommendations for consumer involvement included a multi-method approach consisting of traditional written surveys, a formal advisory group, and monthly consumer led social support/informal input groups. Specific challenges discussed included winter weather conditions, transportation barriers, physical limitations, confidentiality concerns, and needs for social support and education. A multiple-method approach would ensure more comprehensive consumer involvement in the programme planning process. It is also evident that methods for incorporating consumer involvement must be adapted to the specific context and circumstances of a given programme.

    Objective: To identify immunological evidence of Zika virus transmission in Thailand. Methods: To undertake a preliminary serosurvey of possible exposure to Zika virus, 21 serum samples from cohort of acute undifferentiated fever patients were examined for immunoreactivity to Zika, Dengue, Japanese encephalitis and Chikungunya envelope antigens by Western blot analysis. Results: Twenty of the 21 serum samples showed immunoreactivity to at least one of the antigens, with seven samples showing immunoreactivity to all antigens. Of particular note, two serum samples showed immunoreactivity only to Zika envelope antigen, with no immunoreactivity to other envelope antigens. Conclusions: This study presents the first evidence of Zika virus transmission in Thailand, although as yet the relationship between transmission and possible cases of Zika fever in Thailand requires further investigation.

    Full Text Available Purpose: This action research aimed at developing an action plan to improve the accessibility to home health care and assistive devices for persons with disabilities in a rural community, and to evaluate changes in the numbers of such persons who received appropriate home health care and assistive devices after a three-month implementation of the action plan.Method: The study was conducted at a sub-district of Maha Sarakham Province, Thailand. The main beneficiaries were 99 persons with disabilities (mean age55.4±18.7 years. Group meetings were organised for persons with disabilities, caregivers, and various community members. An action plan for improving the accessibility of persons with disabilities to home health care and assistive devices was collaboratively formulated and implemented for three months.Results: The main strategy for improving accessibility was to increase the competency of village health volunteers in providing home health care and assistive devices to persons with disabilities. After the three-month action plan implementation, the number of persons with disabilities who received appropriate home health care, i.e. at least once a month, significantly increased from 33.3% to 72.2% (Chi-square test, PConclusions: Under the supervision of physical therapists and/or other allied health professionals, the village health volunteer is likely to be a key person for improving the accessibility to home health care and assistive devices for persons with disabilities in a rural community.Limitations: The study was limited to only one sub-district. No comparable areas were studied. Further, since the study recruited persons with disabilities from a rural community, applicability of the findings to persons with disabilities in an urban community should be considered judiciously.

    The malnutrition of children under five years of age constitutes a major public health problem in most developing countries. A cross-section study was carried in 2003 in the northern part of Côte d'Ivoire to determine the prevalence of chronic malnutrition and to identify risk factors among children under five years of age living in urban and rural areas of the northern part of Côte d'Ivoire. A total of 292 and 268 children under five years of age residing respectively in urban and rural areas were included in the study. Their median age was 24 months. Chronic malnutrition was more frequent in children from rural areas (39.9%) than in those living in urban areas (16.7%). Malnutrition was significantly associated with the type of food consumed by children under two years of age in urban areas, and it was strongly linked to emaciation of the mother and presence of childhood fever in rural areas. In light of these results, we advocate a healthy diet and adequate health status for the mother and child to improve the nutritional status of children. Moreover, these results need to be completed and complemented by further studies for more detailed information to contribute to a better definition of actions to fight efficiently against malnutrition among children of the northern part of Côte d'Ivoire.

    At present, fossil fuel energy is commonly used in developing countries, including Thailand. The tendency to use fossil fuel energy is continuously increasing, and the price of fossil fuels is rising. Thus, renewable energy is of interest. Hydropower is one of the oldest renewable energy forms known and one of the best solutions for providing electricity to rural communities. The present paper aims to determine the potential micro-hydropower sites that could provide more than 50 kW but not over 10 MW in Nakhon Ratchasima Province, Thailand. Both reservoir and run-of-the-river schemes are considered for the assessment of potential micro-hydropower sites. For the reservoir scheme, the discharge in the reservoir is employed for generating micro-hydropower electricity. This installation can be carried out without major modifications to the dam. The run-of-the-river scheme diverts water flow from the river mainstream to the intake via a pressure pipe or an open canal, which is then conveyed to the turbine via a penstock to generate electricity. The results showed that there are 6 suitable projects for the reservoir scheme and 11 suitable projects for the run-of-the-river. The maximum power load was 6000 kW and 320 kW for the reservoir and the run-of-the-river schemes, respectively. Hydropower from the run-of-the-river scheme is more suitable than hydropower from the reservoir scheme because of the many mountains in this province. The designed head for the run-of-the-river scheme is thus generally higher than that for the reservoir scheme. Because stream flow during the dry season is very low, electricity can only be produced in the wet season. This research is a pilot study to determine the potential sites of micro-hydropower projects. (author)

    The objective of the present study was to identify barriers to and facilitators of physical activity among American Indian adults living on a rural, U.S. Northern Plains reservation using the nominal group technique (NGT). NGT is a method of data generation and interpretation that combines aspects of qualitative (free generation of responses) and quantitative (systematic ranking of responses) methodologies. Adults participated in one of two NGT sessions asking about either barriers to (n = 6), or facilitators of (n = 5), being physically active. Participants nominated and ranked 21 barriers and 18 facilitators. Barriers indicated lack of knowledge of how to fit physical activity into a daily schedule, work, caring for family members, and prioritizing sedentary pursuits. Other responses included environmental barriers such as lack of access and transportation to a gym, unsafe walking conditions, and inclement weather. Facilitators to following recommendations included knowledge of health benefits of physical activity and the perception of physical activity as enjoyable, including feeling good when working out. Environmental facilitators included being outdoors walking and biking as well as parks and exercise facilities. Responses provided direction for locally designed community-based programs to promote facilitators and decrease barriers to individual's engagement in physical activity.

    Full Text Available Abstract Background Population movements along the Thailand-Cambodia border, particularly among highly mobile and hard-to-access migrant groups from Cambodia and Myanmar, are assumed to play a key role in the spread of artemisinin resistance. Data on treatment-seeking behaviours, knowledge and perceptions about malaria, and use of preventive measures is lacking as characteristics of this population prevent them from being represented in routine surveillance and the lack of a sampling frame makes reliable surveys challenging. Methods A survey of migrant populations from Cambodia and Myanmar was implemented in five selected rural locations in Thailand along the Thai-Cambodian border using respondent driven sampling (RDS to determine demographic characteristics of the population, migratory patterns, knowledge about malaria, and health-care -seeking behaviours. Results The majority of migrants from Myanmar are long-term residents (98% with no plans to move back to Myanmar, understand spoken Thai (77% and can therefore benefit from health messages in Thai, have Thai health insurance (99% and accessed public health services in Thailand (63% for their last illness. In comparison, the majority of Cambodian migrants are short-term (72%. Of the short-term Cambodian migrants, 92% work in agriculture, 18% speak Thai, 3.4% have Thai health insurance, and the majority returned to Cambodia for treatment (45%, self-treated (11%, or did not seek treatment for their last illness (27%. Conclusion Most highly mobile migrants along the Thai-Cambodia border are not accessing health messages or health treatment in Thailand, increasing their risk of malaria and facilitating the spread of potentially resistant Plasmodium falciparum as they return to Cambodia to seek treatment. Reaching out to highly mobile migrants with health messaging they can understand and malaria diagnosis and treatment services they can access is imperative in the effort to contain the spread of

    2017-08-01

    In this work, a mathematical model for describing diphtheria transmission in Thailand is proposed. Based on the course of diphtheria infection, the population is divided into 8 epidemiological classes, namely, susceptible, symptomatic infectious, asymptomatic infectious, carrier with full natural-acquired immunity, carrier with partial natural-acquired immunity, individual with full vaccine-induced immunity, and individual with partial vaccine-induced immunity. Parameter values in the model were either directly obtained from the literature, estimated from available data, or estimated by means of sensitivity analysis. Numerical solutions show that our model can correctly describe the decreasing trend of diphtheria cases in Thailand during the years 1977-2014. Furthermore, despite Thailand having high DTP vaccine coverage, our model predicts that there will be diphtheria outbreaks after the year 2014 due to waning immunity. Our model also suggests that providing booster doses to some susceptible individuals and those with partial immunity every 10 years is a potential way to inhibit future diphtheria outbreaks.

    The microbiota of lactic acid bacteria (LAB) in thirty-five samples of Miang, a traditional fermented tea leaf product, collected from twenty-two different regions of eight provinces in upper northern Thailand was revealed through the culture-dependent technique. A total of 311 presumptive LAB strains were isolated and subjected to clustering analysis based on repetitive genomic element-PCR (rep-PCR) fingerprinting profiles. The majority of the strains belonged to the Lactobacillus genera with an overwhelming predominance of the Lb. plantarum group. Further studies of species-specific PCR showed that 201 of 252 isolates in the Lb. plantarum group were Lb. plantarum which were thus considered as the predominant LAB in Miang, while the other 51 isolates belonged to Lb. pentosus. In contrast to Lb. plantarum, there is a lack of information on the tannase gene and the tea tannin-tolerant ability of Lb. pentosus. Of the 51 Lb. pentosus isolates, 33 were found to harbor the genes encoding tannase and shared 93-99% amino acid identity with tannase obtained from Lb. pentosus ATCC 8041 T . Among 33 tannase gene-positive isolates, 23 isolates exhibited high tannin- tolerant capabilities when cultivated on de Man Rogosa and Sharpe agar-containing bromocresol purple (0.02 g/L, MRS-BCP) supplemented with 20% (v/v) crude tea extract, which corresponded to 2.5% (w/v) tannins. These Lb. pentosus isolates with high tannin-tolerant capacity are expected to be the high potential strains for functional tannase production involved in Miang fermentation as they will bring about certain benefits and could be used to improve the fermentation of tea products.

  12. Rural-to-urban migration and its implications for poverty alleviation.

    This article examines rural-urban migration, its role in poverty alleviation in Thailand, and policy implications. The empirical research literature suggests that the poorest tend be left behind by wealthier migrants moving to urban areas. The youngest tend to migrate. The impact of remittances tends to appear more positive in international migration, but the impact of remittances among rural internal migrant families can also be substantial and be responsible for wealth differences within rural communities. Return migrants contribute to communities by bringing back new ideas and new attitudes toward family size. Migration can also produce negative impacts for sending communities, but the total analysis appears to favor positive impacts. The urban sector becomes another resource base for rural populations that can sustain rural populations during rapid change processes. The migrant population tends to be wealthier and better educated than rural populations, but poorer and less educated than urban populations. Informal sectors in urban areas may offer migrants flexible working hours, no taxes or deductions, less bureaucratic structures, and only 9% less income than the formal sector. Social networks reinforce migrant work in the informal sector and segmentation of the labor force. Social networks may be formalized into associations and help in securing migrant's housing and living. Migrants are integrated in a variety of ways into city life. Migrant communities are a source of energy, organizational skills, and talent. The incidence of poverty appears to be the greatest among women. Women migrants and women left behind by migrants must adjust to new conditions. Migration policies tend to focus on regulating the volume of migration. The author concludes that migration alleviates poverty and that policies should address city management, migrant adjustment processes, and training programs for nonmigrants.

    In Australia, faecal incontinence, the involuntary loss of liquid or solid stool with or without a person's awareness, has been reported in 8% of the South Australian and 11% of the urban New South Wales community-dwelling populations. Studies conducted in 2004 and 2005 reported faecal incontinence in more than 20% of colorectal and urogynaecological clinic patients at Townsville Hospital (a referral centre serving rural North Queensland). This prompted concern regarding the level of faecal incontinence in the community. The aim of this study was to investigate the prevalence of faecal incontinence in the North and Far North Queensland urban and rural communities. The sample size was based on the New South Wales postal surveys (11% prevalence). Higher rates were expected in North/Far North Queensland, so prevalence there was estimated at 12.1% (confidence interval ± 2%, ie the true level to be between 10.1% and 14.1%). The sample for each of the Townsville, Cairns (in Far North Queensland) and rural/remote settings was calculated at 1022. The database for the present study was compiled using a systematic randomised process selecting two private names from each column on each page of the Cairns and Townsville White Pages® (Cairns: 1112 urban, 481 rural, 226 remote; Townsville: 1049 urban, 432 rural, 320 remote). The questionnaire covered personal demographics, health/risk factors, bowel habits, nutrition (fibre and fluid intake) and physical activity. Faecal incontinence was defined as accidental leakage of solid or liquid stool in the past 12 months that was not caused by a virus, medication or contaminated food. To improve the response rate a participation incentive of a chance to win a $250 voucher or one of ten $50 vouchers was offered in the initial mail-out. The initial survey was mailed out in July 2007; two follow-up surveys were mailed out to non-responders in September 2007 and January 2008. One hundred randomly selected non-responders were telephoned in

    Yulin region is located in the northern part of Shaanxi Province, China. The winter here is very cold and it has a long duration. In this paper, a rural residence which was located in Yulin region was taken as a study object. Indoor thermal environment of the rural residence were tested, including indoor air temperature and air relative humidity. Then, test data were analyzed. It was summarized that indoor thermal environment of test room can not fully meet human thermal comfort needs, and some tactics of regulation building thermal environment were proposed. This research contributes to improvement of indoor thermal environment for local rural residences and it provides reference for rural residences in other cold regions.

  16. REGIONAL SPECIALIZATION AND INDUSTRIAL CONCENTRATION IN THAILAND, 1996-2005

    2009-06-01

    Full Text Available This paper provides a descriptive analysis of the changes in the industrial and spatial concentration that occurred in Thailand from 1996 to 2005. Based on the data from the Department of Industrial Work of the Ministry of Industry and using the Hirschman-Herfindahl index of concentration, the geographical concentration of industries in the study regions was measured. The Hirschman-Herfindahl index has the useful property of being decomposable into sources of changes in the concentration. Moreover, location quotient was also used to measure the regional specialization of the manufacturing industries in Thailand. Results of the analysis indicated that from 1996 to 2005, the decrease in the spatial concentration of manufacturing as well as in the regional specialization in manufacturing in Thailand remained stable to a lesser extent. The results have also indicated that most factories continue to be concentrated in Bangkok and its neighboring areas. It can therefore be best argued that in the case of Thailand, the effect of its trade liberalization policy has been more powerful than its industrial decentralization policy.

    The study of inborn errors of metabolism (IEM) in Thailand is in its infancy. The majority are clinically diagnosed since there are only a handful of clinicians and scientists with expertise in inherited metabolic disorders, shortage of well-equipped laboratory facilities and lack of governmental financial support. Genetic metabolic disorders are usually not considered a priority due to prevalence of infectious diseases and congenital infections. From a retrospective study at the Medical Genetics Unit, Department of Pediatrics, Siriraj Hospital; estimated pediatrics patients with suspected IEM were approximately 2-3 per cent of the total pediatric admissions of over 5,000 annually. After more than 10 years of research and accumulated clinical experiences, a genetic metabolic center is being established in collaboration with expert laboratories both in Bangkok (Chulabhorn Research Institute) and abroad (Japan and the United States). Numerous inherited metabolic disorders were identified--carbohydrate, amino acids, organic acids, mitochondrial fatty acid oxidation, peroxisomal, mucopolysaccharidoses etc. This report includes the establishment of genetic metabolic center in Thailand, research and pilot studies in newborn screening in Thailand and a multicenter study from 5 institutions (Children's National Center, King Chulalongkorn Memorial Hospital, Pramongkutklao Hospital, Ramathibodi and Siriraj Hospitals). Inherited metabolic disorders reported are fructose-1,6-bisphosphatase deficiency, phenylketonuria, homocystinuria, nonketotic hyperglycinemia, urea cycle defect (arginino succinate lyase deficiency, argininosuccinate synthetase deficiency), Menkes disease, propionic acidemia and mucopolysaccharidoses (Hurler, Hurler-Scheie).

    Full Text Available In the age of globalization, Japanese companies are globalizing their operations. They have recently been increasing the number of overseas R&D centers in Asia, especially in China and Thailand. Using the United States patent and industrial design data, the paper finds the following points quantitatively. Japanese companies are increasing the number of patents and industrial designs created in the two countries. They used local talents from the beginning in China for both patents and industrial designs. In Thailand, they used local talents for industrial designs from the beginning, while Japanese expertise in Thailand was used for patents in the beginning. In any case, the role of Japanese in Japan is important. Compared with multi-national companies (MNCs from other countries, the IP creation activities of Japanese companies are weak compared to their amount of foreign direct investment to China and Thailand.

    Full Text Available Thai indigenous chickens (Gallus domesticus have been domesticated in rural villages in Thailand for a long time. These birds are important to low-income people who live in the rural part of Thailand. However, health problems have been a major cause limiting their population. Hematological, electrolyte and serum biochemical values, which are important for diagnosis of clinical signs and symptoms when affected by diseases, are limited. Blood samples from 40 chickens (20 males and 20 females were used for hematological test while another 18 samples (from 10 males and 8 females were analysed for electrolyte and serum biochemical values. The samples were obtained from Khon Kaen, Kalasin, Roi - Et, Maha Sarakham and Nakhon Ratchasima provinces, northeastern region of Thailand. The results revealed the following information: total red blood cell count, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cell count, lymphocyte, heterophil, monocyte, eosinophil, basophil, H:L ratio values of Thai native chickens were 2.26 ± 0.29 × 106 cells/μl, 8.89 ± 1.20 g/dl, 32.18 ± 4.46%, 144.63 ± 18.61 fl, 39.69 ± 4.96 pg, 27.86 ± 3.37 g/dl, 2.04 ± 0.45 × 104 cells/μl, 63.68 ± 9.36%, 23.70 ± 7.21%, 4.20 ± 3.20%, 5.83 ± 3.53%, 2.65 ± 2.09% and 0.40 ± 0.17, respectively. Potassium, sodium and chloride values of Thai native chickens were 5.3 ± 0.8 mmol/l, 155.9 ± 3.1 mmol/l and 116.9 ± 2.7 mmol/l, respectively. Furthermore, serum biochemistry values of Thai native chickens such as total protein, glucose, alkaline phosphatase, uric acid, calcium and cholesterol were 4.6 ± 1.0 mg/dl, 190.2 ± 29.8 mg/dl, 235.9 ± 68.6 U/L, 5.0 ± 1.9 mg/dl, 10.4 ± 1.2 mg/dl and 102.4 ± 30.8 mg/dl, respectively.

    Stroke is a major public health problem worldwide. There are limited data on national stroke prevalence and outcomes after the beginning of the thrombolytic therapy era in Thailand. This study aimed to investigate the prevalence and factors associated with mortality in stroke patients in Thailand using the national reimbursement databases. Clinical data retrieved included individuals under the universal coverage, social security, and civil servant benefit systems between 1 October 2009 and 30 September 2010. The stroke diagnosis code was based on the International Classification of Diseases 10th revision system including G45 (transient cerebral ischemic attacks and related syndromes), I61 (intracerebral hemorrhage), and I63 (cerebral infarction). The prevalence and stroke outcomes were calculated from these coded data. Factors associated with death were evaluated by multivariable logistic regression analysis. We found that the most frequent stroke subtype was cerebral infarction with a prevalence of 122 patients per 100,000 of population, an average length of hospital stay of 6.8 days, an average hospital charge of 20,740 baht (∼$USD 691), a mortality rate of 7%, and thrombolytic prescriptions of 1%. The significant factors associated with stroke mortality were septicemia, pulmonary embolism, pneumonia, myocardial infarction, status epilepticus, and heart failure. In conclusion, the prevalence and outcomes of stroke in Thailand were comparable with other countries. The era of thrombolytic therapy has just begun in Thailand. Copyright © 2014 Elsevier Ltd.

    2009-02-01

    This study examines construction waste generation and management in Thailand. It is estimated that between 2002 and 2005, an average of 1.1 million tons of construction waste was generated per year in Thailand. This constitutes about 7.7% of the total amount of waste disposed in both landfills and open dumpsites annually during the same period. Although construction waste constitutes a major source of waste in terms of volume and weight, its management and recycling are yet to be effectively practiced in Thailand. Recently, the management of construction waste is being given attention due to its rapidly increasing unregulated dumping in undesignated areas, and recycling is being promoted as a method of managing this waste. If effectively implemented, its potential economic and social benefits are immense. It was estimated that between 70 and 4,000 jobs would have been created between 2002 and 2005, if all construction wastes in Thailand had been recycled. Additionally it would have contributed an average savings of about 3.0 x 10(5) GJ per year in the final energy consumed by the construction sector of the nation within the same period based on the recycling scenario analyzed. The current national integrated waste management plan could enhance the effective recycling of construction and demolition waste in Thailand when enforced. It is recommended that an inventory of all construction waste generated in the country be carried out in order to assess the feasibility of large scale recycling of construction and demolition waste.

    Thailand has embarked upon the development of nuclear energy for peaceful utilizations since 1961 when the Atomic Energy for Peace Act was enacted. The Atomic Energy Commission (Thai AEC) was established under section 5 of this Act having power and duty of carrying out matters concerning atomic energy for peace. The applications of nuclear energy in Thailand, at present are exclusively in medicine, education, research and industry. In this paper, the following items are described on contamination monitoring: controllable monitoring, uncontrollable monitoring, standardization of monitoring instruments, and decontamination and waste management.

    A glimpse at the life of an illustrious Buddhist monastic curer in Pattani, Thailand, reveals a significant multiethnic component of Southeast Asia's traditional medical systems. The prominence of this curer and the prosperity of his monastery derive in large part from his command of alien occult knowledge, which he uses to combat outside supernatural aggression. The paper concludes with a discussion of how centers of outside magical power are conceptualized among various groups in Thailand.

    Several trace elements discharged by the petrochemical industry are toxic to humans and the ecosystem. In this study, we assessed airborne trace elements in the vicinity of the Map Ta Phut petrochemical industrial complex in Thailand by transplanting the lichen Parmotrema tinctorum to eight industrial, two rural, and one clean air sites between October 2013 and June 2014. After 242 days, the concentrations of As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Ti, V, and Zn in lichens at most industrial sites were higher than those at the rural and the control sites; in particular, As, Cu, Mo, Sb, V, and Zn were significantly higher than at the control site (p industrial sites. Principal component analysis (PCA) showed that most elements were associated with industry, with lesser contributions from traffic and agriculture. Based on the pollution load indexes (PLIs), two industrial sites were highly polluted, five were moderately polluted, and one had a low pollution level, whereas the pollution load at the rural sites was comparable to background levels. This study reinforces the utility of lichens as cost-effective biomonitors of airborne elements, suitable for use in developing countries, where adequate numbers of air monitoring instruments are unavailable due to financial, technical, and policy constraints.

    According to demographic changes, the size of the aging population has rapidly increased. Thailand has been facing the "aging society" since 2005 and the "aged society" has been projected to appear by the year 2025. Increased life expectancy is associated with health problems and risks, specifically chronic diseases and disability. Aging and aged societies and related specific conditions as stroke require the provision of services from health professionals. The shortage of the physical therapy workforce in Thailand has been reported. This study investigated the size of physical therapy workforce required for the approaching aging society of Thailand and estimated the number of needed physical therapists, specifically regarding stroke condition. Evidently, the issue of the physical therapy workforce to serve aging and aged societies in Thailand requires advocating and careful arranging.

    The Doi Inthanon and Doi Suthep metamorphic core complexes in northern Thailand are comprised of amphibolite-grade migmatitic gneisses mantled by lower-grade mylonites and metasedimentary sequences, thought to represent Cordilleran-style core complexes exhumed through the mobilization of a low-angle detachment fault. Previous studies have interpreted two metamorphic events (Late Triassic and Late Cretaceous), followed by ductile extension between the late Eocene and late Oligocene, a model which infers movement on the detachment at ca. 40 Ma, and which culminates in a rapid unroofing of the complexes in the early Miocene. The Chiang Mai Basin, the largest such Cenozoic Basin in the region, lies immediately to the east. Its development is related to the extension observed at Doi Inthanon and Doi Suthep, however it is not definitively dated, and models for its development have difficulty reconciling Miocene cooling ages with Eocene detachment movement. Here we present new in-situ LA-ICP-MS and SIMS U-Pb age data of zircon and monazite grains from gneiss and leucogranite samples taken from Doi Inthanon and Doi Suthep. Our new zircon data exhibit an older age range of 221-210 Ma, with younger ages of ca. 72 Ma, and 32-26 Ma. Our monazite data imply an older age cluster at 83-67 Ma, and a younger age cluster of 34-24 Ma. While our data support the view of Indosinian basement being reworked in the Cretaceous, they also indicate a late Eocene-Oligocene tectonothermal event, resulting in prograde metamorphism and anatexis. We suggest that this later event is related to localized transpressional thickening associated with sinistral movement on the Mae Ping Fault, coupled with thickening at the restraining bend of the Mae Yuan Fault to the immediate west of Doi Inthanon. Further, this upper Oligocene age limit from our zircon and monazite data would imply a younger Miocene constraint on movement of the detachment, which, when combined with the previously recorded Miocene

This was a quasi-experimental study in an intervention group and a control group. It was carried out in two rice farming communities, in which most people are rice farmers with similar socio-demographic characteristics. Multistage sampling was employed, selecting one person per rice farming household. The intervention group was 62 randomly selected rice farmers living in a rural area; another 55 rice farmers served as the control group. A structured face-to-face interview questionnaire was administered to participants to evaluate their safety behaviors in four areas: equipment use, pesticide use, ergonomics, and working conditions. The 2-week intervention program consisted of four elements: 1 health education, 2 safety inspection, 3 safety communication, and 4 health surveillance. Data were collected at baseline and 4 months after the intervention (follow-up. We used a general linear model repeated-measures analysis of variance to assess the mean difference between baseline and follow-up occupational safety behavior points between the intervention and control groups. Pesticide safety behaviors significantly increased in the intervention group compared with the control group. Ergonomics and working conditions points also increased in the intervention group, but not significantly so. The equipment use score decreased in the intervention group. It is necessary to identify and develop further measures to improve occupational safety behaviors. Some

  14. Spatial and temporal Teleconnections of Sea Surface Temperature and Ocean Indices to regional Climate Variations across Thailand - a Pathway to understanding the Impact of Climate Change on Water Resources

    2010-05-01

    Thailand has a long coastline with the Pacific Ocean, as part of the Gulf of Thailand, as well as with the Indian Ocean, as part of the Andaman Sea. Because of this peculiar location, Thailand's local climate and, in particular, its water resources are strongly influenced by the mix of tropical wet, tropical dry and tropical monsoon seasons. Because of the large seasonal and interannual variations and irregularities of these, mainly ocean-driven weather patterns, particularly in recent times, large-scale water storage in huge river-fed reservoirs has a long tradition in Thailand, providing water for urban, industrial and agricultural use during long dry seasonal periods. These reservoirs which are located all over Thailand gather water primarily from monsoon-driven rainfall during the wet season which, usually, lasts from May to October. During the dry season, November to April, when the monsoon winds move northward, the air masses are drier in central and northern Thailand, with rain falling here only a few days in a month. Southern Thailand, on the other hand, which is constituted mostly by the isthmus between the two oceans, stays even hot and humid during that time period. Because of this tropical climate pattern, the surface water resources in most of Thailand strongly hinge on the monsoon movements which, in turn, depend themselves upon the thermal states of the Pacific and Indian Oceans. Therefore, the understanding of the recent strong seasonal and interannual climate variations with their detrimental effects on the availability of hydrological water resources in most parts of Thailand, must include the analysis of changes of various sea-state indices in the adjacent oceans and of their possible teleconnections with regional climate indices across this country. With the modern coupled atmospheric-ocean models being able to predict the variations of many ocean indices over a period of several months, namely, those driven by El Nino- Southern Oscillations

    This paper explores a potential relationship between rainfall data and household self-reported harvest shocks and local (spatial) variability of harvest shocks and coping strategies based on a survey of 2700 rural households in the Kagera region of northern Tanzania. In addition, correlations...... of household reported harvest shocks differs significantly between districts and correspond to the observed variability in local climate patterns. Coping strategies are focused on spreading risks and include reduced consumption, casual employment, new crops, external support and the selling of assets....... There are no large differences in applied coping strategies across the region, but district-level data demonstrate how local strategies differ between localities within the districts. The results emphasize that in order to target rural policies and make them efficient, it is important to take into account the local...

  16. Geochemical and geochronological constrains on the Chiang Khong volcanic rocks (northwestern Thailand) and its tectonic implications

    2013-12-01

    Volcanic rocks in northwestern Thailand exposed dominantly in the Chiang Khong area, are commonly considered to be genetically linked to the tectonic evolution of the Paleo-Tethyan Ocean. The volcanic rocks consist mainly of andesitic to rhyolitic rocks and are traditionally mapped as Permian-Triassic sequences. Our zircon U-Pb geochronological results show that two andesitic samples (TL-1-B and TL-31-B), are representative of the Doi Yao volcanic zone, and give a mean weighted age of 241.2±4.6 Ma and 241.7±2.9 Ma, respectively. The rhyolitic sample (TL-32-B1) from the Doi Khun Ta Khuan volcanic zone erupted at 238.3±3.8 Ma. Such ages indicate that Chiang Khong volcanic rocks erputed during the early Middle Triassic period. Seven samples from the Doi Yao and Doi Khun Ta Khuan zones exhibit an affinity to arc volcanics. Three rhyolitic samples from the Chiang Khong area have a geochemical affinity to both arc and syn-collisional volcanic rocks. The Chiang Khong arc volcanic rocks can be geochemically compared with those in the Lampang area in northern Thailand, also consistent with those in Jinghong area of southwestern Yunnan. This indicates that the Chiang Rai arc-volcanic zone might northwardly link to the Lancangjiang volcanic zone in southwestern China.

    Full Text Available Background: Ascariasis and trichuriasis are the most common intestinal geohelminthic diseases, and as such they are significant in terms of clinical and public health. This study was done to determine prevalence, status and geographic distribution patterns for Ascariasis and Trichuriasis. The study was done in the period 1991-2014 in northern Iran using Aregis 9.2 software. Methods: This was a review study, using description and analysis, of geographical distribution of Ascaris and Trichuris relating to townships in Mazandran province, northern Iran, covering a 23-year period. Data were collected from a review of the relevant literature, summarized and classified using Arc GIS, 9.2 to design maps and tables. Results: Based on results presented in tables and maps, means for prevalence of Ascaris and Trichuris were divided into five groups. The maximum prevalence rate of Ascaris was 16.3% reported in rural areas of Tonkabon in 1981-1982. Prevalence means for Ascaris in the central and western areas of Mazandaran province were 2%-4% and 4%, respectively. The maximum prevalence of Trichuris in the rural area of Tonkabon was 22.5% and the lowest 0.06% was among the cattle breeder’s in rural areas of the province at in 2002-2003. Conclusion: Data presented in this study provides information useful to health care workers researchers and health administrators, especially for physicians, clinicians and for future research. Also, it is necessary to control and prevent geohelminthic parasitic infections, particularly in rural areas by public education for families, health authorities and health care systems.

    Full Text Available The paper outlines the evolution of rural cultural landscapes in Poland against the background of landscape classification. It defines cultural landscape types and subtypes, based on several criteria of landscape classification, such as: genetic, morphological, functional, and economic. A review of rural landscapes, based on genetic criteria, considers the following historical periods: the primeval community, the feudalism, the manorial system, the industrial revolution, the interwar period of 1918 – 1939, the period of socialist economy, and market economy. The processes that most significantly influenced the contemporary shape of the rural landscape occurred just after the Second World War: urbanization and industrialization, settlement in western and northern territories, as well as structural and spatial transformations that took place after the year 1989 related to the promotion of sustainable and multifunctional development of rural areas.

    Full Text Available This paper explores the vitality and endangerment of So [sss] speech communities in Thailand. Beginning with a review of sociolinguistic survey results for five So communities in Thailand to ascertain the likely need for vernacular language development in So, additional data to cover the rest of the So community are provided. The language vitality of the So communities in Thailand is then assessed using Expanded GIDS and the Sustainable Use Model (SUM, Lewis & Simons 20152, an expansion of the Graded Intergenerational Disruption Scale (GIDS, Fishman 1991. This vitality model indicates that many So villages display vigorous language vitality whereas other villages are threatened by language shift. Some initial efforts at revitalization and language development show promise. Several additional activities are suggested to enhance the vitality of the language and help the So to resist the regional trend towards language shift to Northeastern Thai (Isaan.

    In 2003, the Cameroon Ministry of the Environment and Forestry has initiated a research project for studying the promotion of renewable energies and their impact on rural development. This work has been realized jointly with the department of Economy and Rural Development of the Agronomic University of Gembloux (Belgium), the Centre Des Etudes de L'Environnement et de Developpement du Cameroun (CEDC, Maroua) and the Institut fur Solare Energieversorgungstechnik (ISET, Germany). This initiative comes when the electricity sector in Cameroon has been facing important changes (Privatization of the national company of electricity, creation of a rural electrification agency, multiplication of the dialogues and seminars around the strategies of promotion for renewable energies, frequent black-outs during the dry season). The first objective of the project is to contribute to a better knowledge of the situation of the use of renewable energies in Cameroon. Therefore, Mrs Marthe Djuikom undertook from July to September 2003 a socio-economic survey on the use of solar energy in the northern Cameroon. The next step will be the creation of an energy program at the CEDC with the following tasks: promotion of photovoltaic technology, support of local and international synergies on the organisational aspects, training, information and coordination of reflexions at the local level for the promotion of rural electrification projects.

    AIM: Here we examine the influence of changes in food retailing, the food supply and the associated nutrition transition on health equity in Thailand, a middle income country experiencing rapid economic development. METHODS: The dietary transition underway in Thailand is reviewed along with theories regarding convergence to a globalised energy dense obesogenic diet and subsequent socio-economically related dietary divergence along with the implications for health inequity. RESULTS: Thailand is part way through a dietary, nutrition and health transition. The food distribution and retailing system is now 50% controlled by modern supermarkets and convenience stores. The problem of increasing availability of calorie dense foods is especially threatening because a substantial proportion of the adult population is short statured due to child malnutrition. Obesity is an emerging problem and for educated Thai women has already developed an inverse relationship to socio-economic status as found in high income countries. CONCLUSIONS: Thailand has reached an important point in its nutrition transition. The challenge for the Thai government and population is to boost affordable healthy diets and to avoid the socio-economic inequity of nutritional outcomes observed in many rich countries.

    In Thailand, the Atomic Energy for Peace Act was enacted by the King in 1961, and Office of Atomic Energy for Peace was established to serve as the secretariat of the Atomic Energy for Peace Commission of Thailand. The import and export of radioactive materials, and the owners and users of radioactive materials must be licensed by the OAEP. The program for establishing the SSDL to calibrate radiation protection instruments started in 1981, and was completed in 1990. The calibration of survey meters and direct reading personnel dosimeters has been provided since 1986. The average number of the devices calibrated by the SSDL per month is shown. The categories of radiation utilization in Thailand are nucleonic gauging and control, nondestructive testing, oil and coal logging, radiation technology and research. The capability of the SSDL and the calibrated radiation measuring instruments for respective categories of utilization are reported. The number of the instruments used for radiography was 217, followed by 171 for nucleonic gauging and control. With the increasing use of radioactive materials, the work of radiation safety must be improved. Together with the license authority, the SSDL must expand its activity to assure the safe handling of radiation sources. (K.I.)

    Full Text Available In the capital city of Thailand, the first electric railway system so called Bangkok Mass Transit System (BTS has been established since 1999. And Thai Government has the master plan to develop the network for such mass transport system in order to reduce traffic congestion and pollution. However, experience and technology knowledge of the rolling stock are still unknown among Thai industries. Besides, the automotive industry in Thailand has shown robust growth despite the political conflict and economic situation. With contribution of component and material suppliers for automotive industry, Thailand has possibly high potential to develop and build the train with local contents based on the international railway industry standards, etc. For this reason, this research focuses on essential component structures for the train, international standards for railway industry and relevant technologies for product, production and testing. In addition, the questionnaire for the component and material suppliers in Thailand has been established under international standards and essential car train components. As a result, it reveals that there are high potential possibilities to support the rolling stock industries under the knowledge of relevant standards in some product modules of the body-strength-structure and auxiliary groups. However, the core knowledge and technologies for the product designs and testing in Thailand are the least in the least in the platformsuspension group.

    Solar energy for process heat is identified as the application with potential for widescale use in rural areas rather than urban centres of Thailand. Three applications of solar energy, namely distillation, drying, and cooking are investigated. The units for the study are designed with low cost, flexibility and durability as the aim. The production efficiency of a conventional solar still is improved by the use of internal or external mirrors. To improve the production and efficiency of a solar still, a suspension of activated carbon particles is introduced into the still. However, the most significant improvement in efficiency and production occurs when the solar still is filled and operated with a static bed of burnt rice husk. The solar dryer, drying tapioca chips can reduce moisture content of around 71% down to 14% within 8 hours of operation. The solar dryer performs more efficiently and effectively than open floor drying. The solar cooker is inconvenient to use and operate and the potential for widescale use is concluded to be remote unless social habits change and the cooker made more comfortable to utilize.

    Full Text Available Bullying is a severe problem, especially in schools, including the relatively new phenomenon of cyberbullying (via mobile phones and the internet. Research in Western countries suggests that over the last decade, cyberbullying accounts for about one-quarter to one-third of all bullying. Here we review research on cyberbullying, and bullying in general, in an eastern culture, Thailand. Eight relevant reports were found; however only three explicitly discussed cyberbullying. Reports were mainly quantitative, and did not consistently distinguish (cyber bullying from general aggression. Suggestions are made for future research in this area, in Thailand and other Southeast Asian countries.

    In much of Thailand animistic curing practices have lost ground to great tradition herbal medicine and modern scientific medicine as more people achieve literacy. Especially in urbanizing areas, Buddhist and Muslim Thais hold in the highest esteem traditional curers whose knowledge derives from patient experimentation and the study of ancient texts. However, among Malay-speaking Muslims in south Thailand, the most respected therapeutic knowledge is revelatory in nature. Southern Muslim curers are generally mystics or spirit-mediums whose direct channels of communication with the supernatural convey remedies for afflictions but also provide guidelines for maintaining sociocultural separatism.

    Latest investigations on atmospheric carbon tetrachloride (CTC) are focused on its ozone depleting potential, adverse effects on the human health, and radiative efficiency and Global Warming Potential as a greenhouse gas. CTC mixing ratios have been thoroughly studied since its restriction under the Montreal Protocol, mostly in remote areas with the aim of reporting long-term trends after its banning. The observed decrease of the CTC background mixing ratio, however, was not as strong as expected. In order to explain this behavior CTC lifetime should be adjusted by estimating the relative significance of its sinks and by identifying ongoing potential sources. Looking for possible sources, CTC was measured with high-time resolution in two sites in Northern Spain, using auto-GC systems and specifically developed acquisition and processing methodologies. The first site, Bilbao, is an urban area influenced by the surrounding industry, where measurements were performed with GC–MSD for a one-year period (2007–2008). The second site, at Valderejo Natural Park (VNP), is a rural background area where measurements were carried out with GC-FID and covering CTC data a nonsuccessive five-year period (2003–2005, 2010–2011, and 2014–2015 years). Median yearly CTC mixing ratios were slightly higher in the urban area (120 pptv) than in VNP (80–100 pptv). CTC was reported to be well mixed in the atmosphere and no sources were noticed to impact the rural site. The observed long-term trend in VNP was in agreement with the estimated global CTC emissions. In the urban site, apart from industrial and commercial CTC sources, chlorine-bleach products used as cleaning agents were reported as promotors of indoor sources. - Highlights: • A methodology was developed to measure CTC using GC-MSD and GC-FID. • CTC ongoing sources were noticed in an industry surrounded urban area. • No noticeable nearby CTC sources impacted the rural site. • Long-term CTC trend in agreement

    Full Text Available The objective of the present study was to identify barriers to and facilitators of physical activity among American Indian adults living on a rural, U.S. Northern Plains reservation using the nominal group technique (NGT. NGT is a method of data generation and interpretation that combines aspects of qualitative (free generation of responses and quantitative (systematic ranking of responses methodologies. Adults participated in one of two NGT sessions asking about either barriers to (n = 6, or facilitators of (n = 5, being physically active. Participants nominated and ranked 21 barriers and 18 facilitators. Barriers indicated lack of knowledge of how to fit physical activity into a daily schedule, work, caring for family members, and prioritizing sedentary pursuits. Other responses included environmental barriers such as lack of access and transportation to a gym, unsafe walking conditions, and inclement weather. Facilitators to following recommendations included knowledge of health benefits of physical activity and the perception of physical activity as enjoyable, including feeling good when working out. Environmental facilitators included being outdoors walking and biking as well as parks and exercise facilities. Responses provided direction for locally designed community-based programs to promote facilitators and decrease barriers to individual’s engagement in physical activity.
