    Recently, elevated dioxin levels, over 5 parts per trillion (ppt) 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), from Agent Orange was reported in 95% of 43 selected residents of Bien Hoa City, a city in southern Vietnam near a former air base used for Agent Orange-spraying missions. Agent Orange herbicide, contaminated with TCDD, was sprayed in Vietnam between 1962 and 1971 primarily for use as a defoliant. Typical blood TCCD levels are 2 ppt in Vietnamese, but levels are as high as 413 ppt in Bien Hoa City. Elevated TCDD was found in children born many years after Agent Orange spraying ended and in immigrants from non-Agent Orange-sprayed parts of Vietnam, which documented new exposures. Extremely elevated soil TCDD samples, over 1 million ppt, and elevated TCDD in sediment were found in some nearby areas such as Bien Hung Lake. The primary route of intake of almost all dioxins in humans is food. However, in our prior studies in Bien Hoa, food was unavailable for dioxin analysis so the route of intake was not confirmed. In the 1970s, while Agent Orange was still being sprayed, elevated human milk TCDD levels as high as 1850 were detected in milk from Vietnamese people living in Agent Orange-sprayed areas where consumption of fish was high. Furthermore, also in the 1970s, elevated TCDD levels (up to 810 ppt) were found in fish and shrimp from the same area as the milk donors. In the 1980s, we found elevated TCDD and also other organohalogen levels in human tissue, pork, fish, a turtle, and a snake in Southern Vietnam. For these reasons, we recently collected food from Bien Hoa and analyzed it for dioxins, polychlorinated biphenyls (PCBs), DDT and its metabolites, and other organochlorines. We found marked elevation of TCDD, the dioxin characteristic of Agent Orange, in some of the food products, including ducks with 276 ppt and 331 ppt wet weight, chickens from 0.031-15 ppt wet weight, fish from 0.063-65 ppt wet weight, and a toad with 56 ppt wet weight.

A food frequency survey of 400 randomly selected households in these wards was conducted to provide data for exposure assessment. Results showed that local residents who had consumed locally cultivated foods, especially fresh water fish and bottom-feeding fish, free-ranging chicken, duck, and beef were at a very high risk, with their daily dioxin intake far exceeding the tolerable daily intake recommended by the WHO. Based on the results of this assessment, a multifaceted risk management program was developed and has been recognized as the first public health program ever to have been implemented in Vietnam to reduce the risks of dioxin exposure at dioxin hot-spots.

    To assess public service providers' knowledge of medical abortion (MA) and practices, and perspectives on expanding the use of MA to primary and secondary health facilities in Vietnam. A cross-sectional study was conducted via an interviewer-administered questionnaire among abortion providers (n=905) from public health facilities between August 2011 and January 2012. Overall, 31.1% of providers performed both surgical and medical abortions; 68.9% offered only surgical abortion. Providers were knowledgeable about the regimen/dosage of mifepristone plus misoprostol regimen; however, knowledge scores were low for gestational age limits for MA, adverse effects of the combined drug regimen, and safety and effectiveness of MA compared with surgical abortion. Knowledge scores were significantly lower among providers in rural areas than among those in urban settings. A large proportion of providers (82.9%) thought that MA should be expanded to primary and secondary health facilities. Perceived barriers to MA expansion included lack of knowledge and training, qualified staff, adequate drug supplies, equipment, or facilities, guidelines and protocols on MA, and patient awareness. Provision of MA in Vietnam was found to be disproportionate to surgical abortion provision and to vary by region. Knowledge of MA was moderate, but poorer among providers in rural settings.

    With an increase in sexual activity among young adults in Vietnam and associated risks, there is a need for evidence-based sexual health interventions. This evaluation of three sexual health programs based on the Protection Motivation Theory (PMT) was conducted in 12 communes in Ha Noi, Nha Trang City, and Ninh Hoa District. Inclusion criteria included unmarried youth 15-20 years residing in selected communes. Communes were randomly allocated to an intervention, and participants were randomly selected within each commune. The intervention programs included Vietnamese Focus on Kids (VFOK), the gender-based program Exploring the World of Adolescents (EWA), and EWA plus parental and health provider education (EWA+). Programs were delivered over a ten-week period in the communities by locally trained facilitators. The gender-based EWA program with parental involvement (EWA+) compared to VFOK showed significantly greater increase in knowledge. EWA+ in comparison to VFOK also showed significant decrease at immediate postintervention for intention to have sex. Sustained changes are observed in all three interventions for self-efficacy condom use, self-efficacy abstinence, response efficacy for condoms, extrinsic rewards, and perceived vulnerability for HIV. These findings suggest that theory-based community programs contribute to sustained changes in knowledge and attitudes regarding sexual risk among Vietnamese adolescents.

    We describe two new species of the genus Cyrtodactylus on the basis of a new reptile collection from the limestone karst forest of Hoa Binh Province, northwestern Vietnam. Cyrtodactylus otai sp. nov. from Hang Kia-Pa Co Nature Reserve and Cyrtodactylus bobrovi sp. nov. from Ngoc Son-Ngo Luong Nature Reserve can be distinguished from each other and from their congeners by their genetic distinction and morphological differences in number of precloacal pores, femoral scales, ventral scales, lamellae, subcaudals and dorsal tubercle arrangement, as well as in size and color pattern. In phylogenetic analyses, both new species are nested in a clade containing taxa from northwestern and northcentral Vietnam and northern Laos, i.e., C. bichnganae and C. cf. martini from northwestern Vietnam, C. puhuensis from northcentral Vietnam, and C. spelaeus, C. vilaphongi, and C. wayakonei from northern Laos.

    Ponds at the former US airbase at Ben Hoa, Vietnam are contaminated with Agent Orange. The ponds had been used for aquaculture, and in all likelihood, fish from those ponds have been sold to the public. We assessed human exposure to 2,3,7,8-tetrachloro-dibenzo-dioxin (2,3,7,8-TCDD) in fish samples from the ponds. For on-base tilapia, muscle concentrations 2,3,7,8-TCDD ranged from 1.4 to 32.7 pg/g. Fat concentrations ranged from 73.3 to 3990 pg/g. Estimated human exposure doses exceed international guidelines and exceed 2,3,7,8-TCDD's lowest adverse effect levels. The Bien Hoa fishponds are a completed human pathway for TCDD exposure.

    Full Text Available Abstract Background Surveys in Vietnam have indicated that wasting and stunting have been prevalent among children, but the country is undergoing rapid socio-economic changes and little has been known about the relative situation in the different areas of the country. In 2006, the WHO introduced new growth standards applicable to all infant and child populations, which facilitates for improved assessments of the prevalence of growth impairment, independent of time, place and ethnicity. The aim of our study was to assess the growth of singleton infants delivered at term in three main birth clinics in the Khanh Hoa province in Vietnam by using the new WHO standards as reference, and the association between growth and some maternal, birth and health factors. Methods A cohort of 237 singleton infants born in the period May-July 2005 in three main delivery clinics in the Khanh Hoa province were observed prospectively. Their anthropometrical measures a year later were compared to the WHO sex-specific growth standards for weight-for-age, length-for-age, weight-for-length, and BMI-for-age. These measures were analysed as dependent outcomes using multiple linear regression models including the following independent factors: urban vs. rural birth, 1-minute Apgar score, weight and length at birth, duration of lactation, ever had diarrhoea, dengue fever, pneumonia or dysentery, and maternal age, height, gestational duration and parity. Results Compared to the standard distributions, 79% were below the median for weight-for-length; 18.0% were within the 5th percentile for length-for-age, 9.6% for weight-for-age, 20.3% for weight-for-length, and 19.8% for BMI. A lower length- and weight-for-age were statistically associated with being born rurally. Conclusions In this delivery-clinic based sample of children in the Khanh Hoa province in Vietnam, the proportions within the WHO-standard 5th percentiles for length-for-age, weight-for-length and BMI in late

    Bien Hoa airbase is a known dioxin-contaminated hotspot in Vietnam. The contamination occurred during the Vietnam War at the site where dioxins were transported, stored, sprayed, and spilled in the area. Dioxins, which are cancer inducing substances, may transfer from the soil to food crops and finally to human beings living around the area. Many surveys of dioxins in soil, water, organisms, and human have been carried out in this study area since 2002. In this paper vertical distribution of dioxins in undisturbed soil cores were examined. Twelve soil samples from three drilled cores were collected to analyze dioxin levels according to the standard Japanese analytical method. The results showed that the toxicity equivalency quantity (TEQ) in one soil sample at a depth of 2.6 m reached 3,300 pg-TEQ/g-dw. High TEQs were also observed in the clay layer. This anomaly of dioxin concentrations could be attributed to the affinity of dioxins for the clay layer. The isomer patterns in the soils were different from those in the soil of Hokkaido in that 2,3,7,8-tetrachlorinated dibenzo-p-dioxin (TCDD) was the most dominant in the soil sample. This indicates that the dioxins originate from a defoliant Agent Orange disposed at the site after the Vietnam War.

    Save the Children/USA and the Ministry of Health of Vietnam undertook a project between 2001 and 2004 to improve the availability of, access to, quality and utilization of emergency obstetric care (EmOC) services at district and provincial hospitals in two provinces in Vietnam. The project improved the functional capacity of 3 provincial and 1 district hospitals providing comprehensive EmOC services, and upgraded 1 district hospital providing basic EmOC into a comprehensive EmOC facility through training, infrastructure and quality improvement. Data presented in this paper focus on only the 2 district hospitals even though the UN process indicators showed increases in utilization of EmOC in all 5 hospitals. In the case of Hai Lang, the proportion of births increased from 13% at baseline to 31% at the end of 2004, and met need increased significantly from 16% to 87% largely due to increased capacity of the hospital and staff. Met need in Hoang Hoa hospital more than doubled (17% at baseline versus 54% in 2004) and the proportion of births increased slightly from 19% in 2001 to 22% in 2004. Case fatality rates for the two hospitals remarkably remained at zero. Lessons from this project have been incorporated into national policy and guidelines. Improvements in the capacity of existing health facilities to treat complications in pregnancy and childbirth can be realized in a relatively short period of time and is an essential element in reducing maternal mortality.

    The potential flood hazard was assessed for the Hoa Chau commune in central Vietnam in order to identify the high flood hazard zones for the decision makers who will execute future rural planning. A new approach for deriving the potential flood hazard based on integration of inundation and flow direction maps is described. Areas inundated in the historical flood event of 2007 were extracted from Advanced Land Observing Satellite (ALOS) phased array L-band synthetic aperture data radar (PALSAR) images, while flow direction characteristics were derived from the ASTER GDEM to extract the depressed surfaces. Past flood experience and the flow direction were then integrated to analyze and rank the potential flood hazard zones. The land use/cover map extracted from LANDSAT TM and flood depth point records from field surveys were utilized to check the possibility of susceptible inundated areas, extracting data from ALOS PALSAR and ranking the potential flood hazard. The estimation of potential flood hazard areas revealed that 17.43% and 17.36% of Hoa Chau had high and medium potential flood hazards, respectively. The flow direction and ALOS PALSAR data were effectively integrated for determining the potential flood hazard when hydrological and meteorological data were inadequate and remote sensing images taken during flood times were not available or were insufficient.

    Agent Orange (AO) was the main defoliant used by the US in Vietnam from 1961 to 1971; AO was contaminated with dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin, or TCDD). Three major dioxin “hot spots” remain from previous AO storage and use at former US bases at Bien Hoa, Da Nang, and Phu Cat, posing potential health risks for Vietnamese living on or near these hot spots. We evaluated potential risk factors contributing to serum TCDD levels in Vietnamese residents at and near contaminated sites in Da Nang and Bien Hoa, Vietnam. We used multiple linear regression to analyze possible associations of blood dioxin concentrations with demographic, socioeconomic, lifestyle, and dietary risk factors for residents living on or near these hot spots. For the Da Nang study, fish farming on the site, living on property flooded from monsoon rains, and age were among the factors showing significant positive associations with serum TCDD concentrations. For the Bien Hoa study, fish farmers working at this site and their immediate family members had significantly higher serum TCDD concentrations. Our results suggest that water-related activities, especially fish-farming, at the hot spots increased the risk of exposure to dioxin.

    The Hoa Binh dam (HBD), located on a tributary of the Red River in Vietnam, has a capacity of 9.45 × 109 m3 and was commissioned in December 1988. Although it is important for flood prevention, electricity production and irrigation in northern Vietnam, the Hoa Binh dam has also highly influenced the suspended sediment distribution in the lower Red River basin, in the delta and in the coastal zone. Its impact was analysed from a 50-year data set of water discharge and suspended sediment concentration (1960-2010), and the distribution of water and sediment across the nine mouths of the delta was simulated using the MIKE11 numerical model before and after the dam settlement. Although water discharge at the delta inlet decreased by only 9%, the yearly suspended sediment flux dropped, on average, by 61% at Son Tay near Hanoi (from 119 to 46 × 106 t yr-1). Along the coast, reduced sedimentation rates are coincident with the lower sediment delivery observed since the impoundment of the Hoa Binh dam. Water regulation has led to decreased water discharge in the wet season (-14% in the Red River at Son Tay) and increased water discharge in the dry season (+12% at the same station). The ratios of water and suspended sediment flows, as compared to the total flows in the nine mouths, increased in the northern and southern estuaries and decreased in the central, main Ba Lat mouth. The increasing volume of dredged sediments in the Haiphong harbour is evidence of the silting up of the northern estuary of Cam-Bach Dang. The effect of tidal pumping on enhanced flow occurring in the dry season and resulting from changed water regulation is discussed as a possible cause of the enhanced siltation of the estuary after Hoa Binh dam impoundment.

Water regulation has led to decreased water discharge in the wet season and increased water discharge in the dry season. Suspended sediment discharge proportionally increased in northern and southern estuaries and decreased through the main and central Ba Lat mouth. Tidal pumping, which causes a net sediment flux from the coast to the estuary at low discharge, is high in the northern delta, as a consequence of the high tidal range (up to 4.5 m in spring tide; diurnal tide. The shifts in the dynamic and characteristics of the turbidity maximum zone in the Cam-Bach Dang estuary are probably the cause of the enhanced sediment deposition in the Haiphong harbor. Along the coast, the reduced sedimentation rates are coincident with the lower sediment delivery that has been observed since the impoundment of the Hoa Binh Dam.

  20. Household opportunity costs of protecting and developing forest lands in Son La and Hoa Binh Provinces, Vietnam

    Full Text Available Vietnam has pilot-tested a payment for forest environmental services (PFES program in an effort to restore and protect forest areas, some of which have been severely degraded by the excessive cutting of trees by small-scale farmers planting annual crops on steep, sloping lands. The pilot program implemented in southern Vietnam seems to be successful, yet the program in northern Vietnam has not produced the desired rates of planting and maintaining forest areas. The reasons for these mixed results include differences in socio-economic characteristics and also the production and marketing opportunities available to rural households in the project areas. To gain insight regarding program participation, we examine the household-level opportunity costs of planting and ­maintaining small plots of forest trees in northern Vietnam. We find that small-scale farmers in Hoa Binh Province, with limited financial resources, prefer the annual revenue stream provided by crops such as maize and cassava, rather than waiting for 7 years to obtain revenue from a forest planting. Farmers in Son La Province, with limited access to markets, prefer annual crops because they are not able to sell bamboo shoots and other forest products harvested from their small plots. In both provinces, the payments offered for planting and maintaining forest trees are smaller than the opportunity costs of planting and harvesting annual crops. Thus, most households likely would choose not to participate in the PFES program, at current payment rates, if given the opportunity to decline.

    The Bien Hoa airbase (south of Vietnam) is known as one of the Agent Orange hotspots which have been seriously contaminated by Agent Orange/dioxin during the Vietnam War. Hundreds of samples including soil, sediment and fish were collected at the Bien Hoa Agent Orange hotspot for assessment of the environmental contamination caused by dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs). The toxicity equivalency quotient (TEQ) concentration of PCDD/Fs in soil and sediment varied from 7.6 to 962,000 and 17 to 4860 pg/g dry wt, respectively, implying very high contamination of PCDD/Fs in several areas. PCDD/F levels in fish ranged between 1.8 and 288 pg/g TEQ wet wt and was generally higher than advisory guidelines for food consumption. 2,3,7,8-Tetrachlorinated dibenzo-p-dioxins (2,3,7,8-TCDD) contributed 66-99 % of TEQ for most of the samples, suggesting 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) from Agent Orange as the major source of the contamination. The vertical transport of PCDD/Fs was observed in soil column with high TEQ levels above 1000 pg/g dry wt (Vietnamese limit for necessary remediation activities- TCVN 8183:2009 (2009)) even at a depth of 1.8 m. The vertical transport of PCDD/Fs has probably mainly taken place during the "Ranch Hand" defoliant spray activities due to the leaks and spills of phenoxy herbicides and solvents. The congener patterns suggest that transports of PCDD/Fs by weathering processes have led to their redistribution in the low-land areas. Also, an estimate for the total volume of contaminated soil requiring remediation to meet Vietnamese regulatory limits is provided.

    A baseline epidemiological survey for parasite infections was conducted between December 2007 and January 2008 in 155 villagers in a rural commune in Hoa Binh province, Vietnam. The prevalence of Ascaris lumbricoides, Trichuris trichiura and hookworm infection was 13.5%, 45.2% and 58.1%, respectively. At least one of the parasites was detected in 72.3% of the samples. We found no association between infection with A. lumbricoides or T. trichiura and engagement in agriculture, while hookworm infection was more prevalent in populations having frequent contact with soil. Agricultural use of human faeces was not correlated with any of the infections. We suggest that the consumption of vegetables that are commonly fertilized with human faeces in the community has led to the high infection rates with A. lumbricoides and T. trichiura, rather than the manipulation of faeces in farming activity. This also explains the high infection prevalence, despite high latrine coverage (98.1%) in the study population. The presence of latrines alone is not sufficient to reduce the prevalence of helminthiasis in a rural agricultural community if fresh faeces are used as fertilizer.

    Gastropod molluscs are one of the most important components of mangrove ecosystem. Mangroves in Central Vietnam have a rather limited distribution due to peculiarities of the coastline morphology and presently their fauna remains understudied. Extensive surveys were conducted in both natural vegetation and artificial mangrove plantations in several localities in Nha Trang Bay from 2005 to 2015. In total 65 species of gastropod molluscs were found alive, 17 of which can be considered as predominantly mangrove-associated. An illustrated guide is provided, with short synonymies and data on ecology and distribution. The recorded molluscan diversity is compared with published data on mangrove gastropods in different regions of the Indo-Pacific. Total species number and the proportion of mangrove-associated species are similar to studied faunas in Hong Kong, Malaysia and Thailand, but the diversity is much lower than that of the mangal fauna of the Philippines.

    Aquaculture is currently one of the most rapidly growing production sectors in Vietnam. This publication describes the concentrations of heavy metals in the farming environment and some aquaculture species in the Khanh Hoa Province in Vietnam. The concentration of total As in the sediments ranged from 0.07 to 0.64 mg/kg, whereas the concentration of Hg varied from <0.0005 to 0.56 mg/kg. The corresponding concentration span for Cd and Pb, were 0.001-0.069 and 0.016-0.078 mg/kg, respectively. The concentrations of As in the aquaculture organisms spanned from 0.14 to 1.03 mg/kg. For Hg the concentrations varied from 0.1 to 0.45 mg/kg, for Cd from 0.02 to 0.10 mg/kg and for Pb from 0.07 to 0.37 mg/kg.

    Floods are recurring events in the Lower Mekong Basin resulting in loss of life and property, causing damage to agriculture and rural infrastructure, and disrupting social and economic activities. Flood management and mitigation has become a priority issue at the national and regional levels. Besides, it is expected that large areas of the Mekong delta, the Red River delta and the central coast will be flooded by sea-level rise due to climate change. Can Tho City is ranked under the five most flood-tide-influenced cities of Vietnam. It is the biggest city in the Mekong delta and it is located near the Hau river. Like other region of the Mekong delta, Can Tho suffers due to floods from upstream and flood tides from the sea. In the flood season large rural areas of the city are flooded, particularly during tidal days. Flood risk management policy includes preparative measures for living with floods and to minimise the damage caused by floods as well as to take advantage of floods for sustainable development. An intensive literature review, including administrative reports as well as expert interviews have been undertaken to gain more insight into flood characteristics, their consequences and risk mitigation. Therefore, flood damaging processes and trends have been reviewed for Can Tho City and the Mekong Basin in Vietnam. Additionally, suitable flood damage estimation methodologies have been collected as important input for flood risk analyses. On this basis it has been investigated which flood risk mitigation and management strategies promise to be effective in Can Tho City, Vietnam.

    Parent-child communication is associated with positive outcomes for youths' engagement in sexual behaviors. Limited data are available regarding parent-child communication in transitional countries. We present data from Vietnamese parent-youth dyads on parent reproductive health (RH) knowledge, comfort of communication, frequency of talk, and discordancy between youths' reported and parents' perceptions for engagement in relationships and sexually intimate behaviors. The cohort included 185 randomly selected parent-youth dyads in four communes in Hanoi and Khanh Hoa Province. Descriptive and comparative analysis included chi-squared tests, independent samples t-tests, and ANOVA. Linear regression analysis was used to assess relationships between parental knowledge, level of comfort, frequency of talk, and discordancy. Seventy-six percent of parents and 44% of youth were female. The mean age of youth was 17.2 years. The mean score for parental "RH knowledge" was 24.74 (SD, 3.84; range, 15-34). Lower parental RH knowledge was positively associated with lower levels of education (F = 2.983; df, 184; p = .014). Data indicate a linear model in which knowledge is related to "comfort" (β = .17; p = .048), and "comfort" to frequency of "talk" (β = .6; p communication about RH. There is a need for more data to assess the effect of these communication patterns on youths' engagement in sexual behaviors and for development of family-centered interventions to increase parental knowledge and skills for positive communication.

    Attention in this discussion of Vietnam is directed to the following: people; geography; history; government; the economy (agriculture and industry, trade and balance of payments); foreign relations; and relations between the US and Vietnam. In mid-1983 the population was estimated at 57,610,000 with an annual growth rate of 2.4%. Ethnic Vietnamese constitute almost 90% of the population. Various ethnic groups make up the remaining 10% of the population, with approximately 1.2 million Chinese being the most numerous and concentrated in southern Vietnam. The 2nd largest minority, the Montagnards (mountain tribesmen) comprise 2 main ethnolinguistic groups--Malayo Polynesia and Mon-Khmer. The most important political institution in Vietnam is the Vietnamese Communisty Party. All but 4 party Politburo members concurrently hold high positions in the government. The most important powers within the Vietnamese government, as opposed to the Communisty Party, are the executive agencies. Under the overly ambitious initial 5 year plan and the more conservative 1981-85 plan, the Vietnamese have made little progress in raising output and living standards beyond the levels of the 1960s. Guidelines of the 1981-85 plan call for attaining food self sufficiency, strengthening export and consumer industries, as well as the heavy industries that support them, and improving transport and energy production. The US does not have diplomatic relations with Vietnam.

    The association between increasing water intensive land-cover, such as the use of turf grass and trees, and increasing water use is a growing concern for water-stressed arid cities. Appropriate regulatory measures addressing residential landscaping, such as those applied by Homeowner Associations (HOAs), may serve to reduce municipal water use, joining other water-use reducing measures under consideration by arid cities. This research assesses quantitatively the role that Covenants, Conditions, and Restrictions (CCRs) applied to landscaping by HOAs play on water consumption. Statistical comparisons and models of n=1973 parcels in Goodyear, Arizona, USA, reveal that: HOA yards have less vegetation cover and those households use less peak-season water (July) than those households in non-HOA neighborhoods. This hold true even though the HOA CCRs regulate only the minimum required front-yard vegetation and most residents maintain more than the minimum vegetation level. Furthermore, front-yard landscaping tends to be mimicked in the backyard such that total yard landscaping tracks best with total household water use. Results of the study suggest that HOA landscaping regulations have the potential to reduce peak-season water use by up to 24% if CCRs were to set maximum vegetation regulations rather than minimum and if compliance were enforced. Lowering residential water consumption in this way potentially involves tradeoffs with the cooling effects of vegetation and its consequences on the urban heat island effect, on energy use, and on home values.

    Full Text Available Japanese encephalitis virus (JEV is a mosquito-borne, zoonotic flavivirus causing encephalitis in humans and reproductive disorder in pigs. JEV is present in large parts of Asia, where urbanization is high. Households within and outside Can Tho city, South Vietnam, were selected to monitor circulation of JEV. A nested RT-PCR was established to detect the presence of JEV in mosquitoes whereas sera from pigs belonging to households within the province were analyzed for the presence of antibodies to JEV. A total of 7885 mosquitoes were collected and divided into 352 pools whereof seven were JEV-positive, six of which were collected within the city. Fragments from four pools clustered with JEV genotype III and three with genotype I. Of the 43 pigs sampled inside the city 100% had JEV antibodies. Our study demonstrates exposure to JEV in pigs, and co-circulation of JEV genotype I and III in mosquitoes within an urban environment in South Vietnam. Thus, although JEV has mainly been considered a rural disease, the potential for transmission in urban areas cannot be ignored.

    Full Text Available Water pollution associated with flooding is one of the major problems in cities in the global South. However, studies of water quality dynamics during flood events are not often reported in literature, probably due to difficult conditions for sampling during flood events. Water quality parameters in open water (canals, rivers, and lakes, flood water on roads and water in sewers have been monitored during the extreme fluvial flood event on 7 October 2013 in the city of Can Tho, Vietnam. This is the pioneering study of urban flood water pollution in real time in Vietnam. The results showed that water quality is very dynamic during flooding, especially at the beginning of the event. In addition, it was observed that the pathogen and contaminant levels in the flood water are almost as high as in sewers. The findings show that population exposed to flood water runs a health risk that is nearly equal to that of being in contact with sewer water. Therefore, the people of Can Tho not only face physical risk due to flooding, but are also exposed to health risks.

    Nowadays, agroforestry farming is a major issue in Vietnamat midland and mountainous region as it has to satisfy the demand of forest production and ecosystem protection. Compared to some other types of forest, agroforest has demonstrated outstanding strength as it provides landowners with early and fast income generation. Therefore, developing agroforest becomes a trend when the research on land use gets much attention. However, environmental efficiency of agroforest is quite varied and closely reliable on the structure of the forest system. Taking into consideration of both environmental condition and the efficiency at the same time is significant not only in evaluating the current situation of the forest but also in improving its structure, thereby reaching environmental goals. Nevertheless, there is a shortage of research on above problem in Hoa Binh hydropower reservoir environment. Due to this restriction many agroforests were in failure to enhance their economic and protective functions and the forest also showed low stability. In order to have a part in solving the aforesaid inadequacies, this paper has been conducted. The environmental protection and soil conservation of vegetation have high requirements in hydropower station reservoir area. Finding a kind of land use pattern that can meet the interests of all parties is particularly important in the context that moving local residents out of the reservoir area is impossible. In the present study, the four main agroforestry system patterns (Acacia mangium-Zea mays;Acacia mangium-Manihot esculenta crantz;Eucalyptus camandulensis-Oryza sativa;Acacia mangium-Manihot esculenta crantz-Zea mays) were employed as the research subjects in two different areas (Thung Nai Commune, Cao Phong District and Vay Nua Commune, Da Bac District) of Hoa Binh hydropower station reservoir area in Vietnam.

    Hai Phong city is located in the Northern coast of Vietnam where the mangroves are distributed between zone I and zone II among the four mangrove zones in Vietnam. This city is vulnerable to rising sea levels associated with climate change and tropical cyclones, which are forecasted to become more severe due to the impact of climate change. In the past, mangrove forests in this city have decreased markedly because of over expansion of shrimp farming. Thus, identification of mangrove forests is important to monitor and support mangrove conservation and management in the coastal zone. The objectives of this research were to identify the locations of mangrove and characterize mangrove species in Hai Phong using HH and HV backscatters of the Advanced Land Observing Satellite 2 (ALOS-2) with enhanced Phased Array L-band Synthetic Aperture Radar (PALSAR). Image segmentation was used to identify the locations of mangrove forests. Moreover, Geographic Information System (GIS) was applied to update current status of mangrove species in 2015. The results showed that the means of HH and HV backscatter coefficients of K. obovata are lower than S. caseolaris. K. obovata has HH value around -13.9 dB until -10.3 dB and HV value around -20.6 dB until -16.2 dB. Higher HH values between about -14.9 dB and -6.8 dB and HV values between roughly -20.6 dB and -14.3 dB have observed by S. caseolaris. The total area of mangrove forest in Hai Phong in the year 2015 was around 4084 hectares, of which S. caseolaris occupied over 68% and mixed mangrove species was approximately 25.6%. This research indicates the potential for the use of L-band ALOS-2 PALSAR in characterizing mangrove forest species in the coastal zone.

    The socio-economic status in Vietnam has developed during the past decades. People become busier for work, and thus they do not have enough time to prepare meal for their children. The school meal program, organized by Department of Education, was first implemented at a kindergarten in 1977, which has been extended to elementary school since 1980. Up to date, 100% of kindergarten and approximately 90% of elementary schools have school meal programs. The purposes of this program are to provide appropriate meals for students, and to serve as education and communication tool for students. About 90% of school meals are prepared in the school's kitchen and the rest are provided by food companies. The weekly menu provides approximately 30% of recommended dietary allowances (RDA) for students. To date, there has been is no official dietitian training school in Vietnam. The head of school kitchen, who is not dietitian, is required to participate in a short-term training course, where s/he learns basic nutrition, nutrition requirements and food hygiene and safety. The food companies, which provide meals to school, must be approved for the hygiene and safety condition by the Human Health Services Department of Ho Chi Minh City. In the next plan of national nutrition strategy, establishing dietitian training schools will be prioritized. In addition, the regular nutritional surveillance for school-aged students will be introduced in school system thus we can develop and evaluate the school meal program in terms of nutrients, food safety and nutrition education.

    In Vietnam, the co-occurrence (i.e., "syndemic") of psychosocial factors (e.g., depression and substance use) may disproportionately burden male sex workers and increase their HIV risk. A comprehensive survey was conducted among 300 male sex workers in Ho Chi Minh City, Vietnam in 2010. We performed logistic regression to examine the association between the syndemic variable-a count score of the number of five psychosocial conditions endorsed-and unprotected anal sex (UAS) in the past. One-third of participants reported any UAS, and 42 % reported ≥2 psychosocial health problems. In multivariable models, experiencing ≥4 psychosocial health problems was significantly associated with UAS. Every unit increase in number of psychosocial health problems was associated with a 25-30 % increase in odds of UAS. Understanding the syndemic condition and its association with HIV risk among male sex workers in Vietnam may lead to the development of more effective, comprehensive interventions.

    Stigma and discrimination against people living with HIV/AIDS (PLHIV) are a pressing problem in Vietnam, in particular because of propaganda associating HIV with the "social evils" of sex work and drug use. There is little understanding of the causes and sequelae of stigma and discrimination against PLHIV in Vietnam. Fifty-three PLHIV participated in focus group discussions in Ho Chi Minh City. Nearly all participants experienced some form of stigma and discrimination. Causes included exaggerated fears of HIV infection, misperceptions about HIV transmission, and negative representations of PLHIV in the media. Participants faced problems getting a job, perceived unfair treatment in the workplace and experienced discrimination in the healthcare setting. Both discrimination and support were reported in the family environment. There is a need to enforce laws against discrimination and provide education to decrease stigma against PLHIV in Vietnam. Recent public campaigns encouraging compassion toward PLHIV and less discrimination from healthcare providers who work with PLHIV have been encouraging.

    SummaryProvision of urban water supplies to rapidly growing cities of South East Asia is difficult because of increasing demand for limited water supplies, periodic droughts, and depletion and contamination of surface and groundwater. In such adverse environments, effective policy and planning processes are required to secure adequate water supplies. Developing a Water Needs Index reveals key elements of the complex urban water supply by means of a participatory approach for rapid and interdisciplinary assessment. The index uses deliberative interactions with stakeholders to create opportunities for mutual understanding, confirmation of constructs and capacity building of all involved. In Can Tho City, located at the heart of the Mekong delta in Vietnam, a Water Needs Index has been developed with local stakeholders. The functional attributes of the Water Needs Index at this urban scale have been critically appraised. Systemic water issues, supply problems, health issues and inadequate, poorly functioning infrastructure requiring attention from local authorities have been identified. Entrenched social and economic inequities in access to water and sanitation, as well as polluting environmental management practices has caused widespread problems for urban populations. The framework provides a common language based on systems thinking, increased cross-sectoral communication, as well as increased recognition of problem issues; this ought to lead to improved urban water management. Importantly, the case study shows that the approach can help to overcome biases of local planners based on their limited experience (information black spots), to allow them to address problems experienced in all areas of the city.

    Full Text Available The paper presents the current situation of the waste management system of the megacity Ho Chi Minh in Vietnam, and the options for waste and land recycling in a low income country. Generally, there is a large potential for circular economy in the city as the main proportion of the waste flows are recyclables. Due to the missing selective collection system, this potential is not used in the full extend yet, even if the collection of the entire waste volumes is envisaged in the National Waste Management Strategy by 2025. The waste stocks are the landfill locations in the region of Ho Chi Minh City (HCMC, two of them being in operation and two of them already being closed. A special focus is given to the landfill Gò Cát, which was subject to an option analysis in terms of waste and land recycling options. The results indicate that there are several reuse options: the use of the landfill material in a waste-to-energy process after landfill mining, the reuse of the re-gained land in case of landfill mining, the reuse of the capped landfill for energy crop cultivation, and the gasification in a biogas plant in case of a remaining landfill.

    2011-12-01

    Full Text Available Urban development increases flood risk in cities due to local changes in hydrological and hydrometeorological conditions that increase flood hazard, and also to urban concentrations that increase the vulnerability. The relationship between the increasing urban runoff and flooding due to increased imperviousness better perceived than that between the cyclic impact of urban growth and the urban rainfall via microclimatic changes. The large-scale, global impacts due to climate variability and change could compound these risks. We present the case of a typical third world city – Can Tho (the biggest city in Mekong River Delta, Vietnam – faced with multiple future challenges, namely: (i climate change-driven sea-level rise and tidal effect, (ii increase river runoff due to climate change, (iii increased urban runoff driven by imperviousness, and (iv enhancement of extreme rainfall due to urban growth-driven micro-climatic change (urban heat islands. A set of model simulations were used to assess the future impact of the combination of these influences. Urban growth of the city was projected up to year 2100 based on historical growth patterns, using a land-use simulation model (Dinamica-EGO. A dynamic limited-area atmospheric model (WRF, coupled with a detailed land-surface model with vegetation parameterization (Noah LSM, was employed in controlled numerical experiments to estimate the anticipated changes in extreme rainfall patterns due to urban heat island effect. Finally, a 1-D/2-D coupled urban-drainage/flooding model (SWMM-Brezo was used to simulate storm-sewer surcharge and surface inundation to establish the increase in the flood risk resulting from the changes. The results show that, if the city develops as predicted, the maximum of inundation depth and area in Can Tho will increase by about 20%. The impact of climate change on inundation is more serious than that of urbanization. The worse case may occur if the sea level rises 100 cm and

    This study quantitatively and qualitatively described HIV risk behaviors among Vietnamese female sex workers (FSWs) who work at three distinct venues in Ho Chi Minh City: street, massage parlors, and bars/clubs. Although 35% of the participants had never been tested for HIV, 18% of street and 7% of bar/club FSWs reported being positive. Almost all massage parlor FSWs had never used a condom for oral sex. Inconsistent condom use for vaginal sex with customers was more prevalent among bar/club FSWs (85%) than massage parlor (72%) and street FSWs (68%). Many participants reported difficulties in negotiating condom use with customers because of economic pressure, maintaining relationships, and lack of bargaining power. Bar/club FSWs revealed a difficult situation where drinking is part of their work. Thirty percent of street FSWs had injected drugs and reported addiction to heroin in relation to their helpless condition as FSWs. Street FSWs had the lowest levels of self-esteem and norms toward practicing safe sex and the highest levels of economic pressure. This study recommends future HIV prevention programs for FSWs in Vietnam that target their specific risk behaviors and work environments.

    Full Text Available Enterovirus 71 (EV71 frequently causes fatal infections in young children in Asia. In 2011, EV71 epidemics occurred in southern Vietnam. We conducted genetic and antigenic analysis of the EV71 isolates and found that 94% of them were genotype C4a related to two lineages circulating in China and 6% were genotype C5 which have circulated in Vietnam since 2003. Antigenic variants were not detected. EV71 vaccines are being developed. Longitudinal enterovirus surveillance data are critical to formulate vaccination policy in Vietnam.

    Full Text Available Abstract Background An increasing prevalence of overweight and obesity has been documented in preschool children in Ho Chi Minh City (HCMC, Vietnam. However, little is known about what preschool children in HCMC eat or how well their nutrient intake meets nutrient recommendations. This study aims to describe the energy and macronutrient intake and compare these nutrient intakes with the recommendations for Vietnamese children aged four to five years. Methods The data comes from the baseline measurement of a one year follow-up study on obesity in 670 children attending kindergartens in HCMC. Dietary information for each child at the school and home settings was collected using Food Frequency Questionnaires (FFQs, by interviewing teachers and parents or main caregivers. The average energy and nutrient intake in a day was calculated. The proportion of children with energy intake from macronutrients meeting or exceeding the recommendations was estimated based on the 2006 recommended daily allowance (RDA for Vietnamese children in this age group. Results The dietary intake of the participants contained more energy from protein and fat, particularly animal protein and fat, and less energy from carbohydrates, than the RDA. Most children (98.1% had mean energy intake from protein greater than the recommended level of 15%, and no child obtained energy from animal fat that was in accordance with the recommendation of less than 30% of the total fat intake. Nearly one half of children (46.5% consumed less than the advised range of mean energy intake from carbohydrate (60%–70%. Conclusion In this preschool child population in HCMC, in which obesity is emerging as major public health problem, there is an imbalance in dietary intake. Healthy eating programs need to be developed as a part of an obesity prevention program for young children in HCMC.

    Full Text Available Sodium benzoate and potassium sorbates are the two typical preservatives widely used in Vietnam and other countries. The maximum level (ML of sodium benzoate and potassium sorbate in processed meat products imposed by Ministry of Public Health is 1000 ppm. Although there are warnings about overusing of these preservatives that related to human health, many manufacturers do not follow the regulations. The aim of this study was to survey and consider the amounts and presence of these preservatives in processed meat products by using High-performance liquid chromatography (HPLC method. 90 samples of brands and no brands including Vietnamese pork rolls, pâtés, hams, sausages, and fermented pork rolls that available at markets in Ho Chi Minh City were analysed for these two preservatives. There was a preference for using sodium benzoate in all samples. Moreover, Vietnamese pork roll samples had the highest percentage of samples with preservatives concentrations exceeding the ML. Among 90 samples, sodium benzoate was detected in 52.2% of samples and 17.8% of them exceeded the ML, while potassium sorbate was found in 24.4% of samples and only 2.2% of them exceeded the regulated amount. 46.4% of Vietnamese pork rolls, 12.5% of pâtés, and 9.1% of fermented pork rolls had sodium benzoate exceeded the ML, whilst ham and sausage samples contained the concentrations inside the safety limits. Furthermore, only one sample of Vietnamese pork rolls and one sample of sausages had potassium sorbate concentrations surpassing the ML with the level of 1,717.57 mg/kg and 1,814.00 mg/kg, respectively. Furthermore, branded samples showed a significantly different result in compared with no branded samples. Of branded samples, exceeding sodium benzoate level ML was detected in 10% of samples and none of the samples found surpassing potassium sorbate limit amount. Nevertheless, 27.5% and 5% of unbranded samples had sodium benzoate and potassium sorbate higher than

    There is little data on the burden of HIV and other infections that affect male sex workers (MSW) in Vietnam. We conducted behavioral and biological sexual health surveys with 300 MSW in Ho Chi Minh City. Generalized estimating equation models were built to assess factors associated with HIV, hepatitis C, and other sexually transmitted infections (STI). Of 300 MSW, 19 (6.3 %) were diagnosed seropositive for HIV, 11 (3.7 %) had hepatitis C, and 26 (8.7 %) had at least one prevalent STI. In a multivariable model, opiate use was significantly associated with HIV infection (aOR 6.46, 95 % CI 1.28-32.7) and hepatitis C (aOR = 19.6, 95 % CI 2.35-163.6). Alcohol dependency was associated with increased odds of hepatitis C (aOR = 4.79, 95 % CI 1.02-22.5) and decreased odds of other STI (aOR = 0.30, 95 % CI 0.10-0.97). These findings suggest that MSW in Vietnam would benefit from regular HIV and STI testing, as well as linkage to care and substance use rehabilitation services.

    To learn more about risk behaviors among men who have sex with men (MSM) in Vietnam and their prevalence of HIV, we conducted a study among MSM in Ho Chi Minh City (HCMC) to determine HIV-1 prevalence and behaviors associated with infection. This consisted of formative (35 MSM) and cross-sectional (600 MSM) studies at 72 sites, including 75 transvestites, 55 bisexuals, 10 sex workers, and 460 other MSM. Only 5.3% cohabited with a wife/girlfriend, but 30% reported ever having sex with a female. Prevalence of HIV was 8%, ranging from 33% in sex workers to 7% among transvestites and other MSM. Injecting drugs, selling sex, being 20-40 years old, having less than 6 years of education, and having more than five male anal sex partners in the past month were associated with being HIV-infected. MSM are an HIV bridge group, and should be included in sentinel surveillance. Targeted interventions should be implemented.

Methods: We conducted a cross-sectional study via interviewer-administered questionnaire among abortion providers from public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City in Vietnam between August 2011 and January 2012. We recruited abortion providers at all levels of Vietnam's public health service delivery system. Participants were questioned about their medical abortion provision practices and perspectives regarding abortion methods. Results: A total of 905 providers from 62 health facilities were included, comprising 525 (58.0% from Hanoi, 122 (13.5% from Khanh Hoa, and 258 (28.5% from Ho Chi Minh City. The majority of providers were female (96.7%, aged ≥25 years (94%, married (84.4%, and had at least one child (89%; 68.9% of providers offered only manual vacuum aspiration and 31.1% performed both medical abortion and manual vacuum aspiration.

    Despite the ban on persistent organochlorines (OCs) in most of the developed nations, their usage continued until recently in many Asian developing countries including Vietnam, for agricultural purposes and vector-borne disease eradication programs. In this study, we collected human breast milk samples from the two big cities in Vietnam: Hanoi (n=42) and Hochiminh (n=44) and determined the concentrations of persistent OCs such as PCBs, DDT and its metabolites (DDTs), hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), chlordane compounds (CHLs) and tris-4-chlorophenyl-methane (TCPMe). The contamination pattern of OCs was in the order of DDTs > PCBs > HCHs > CHLs{approx}HCB{approx}TCPMe. Compilation of available data indicated that DDT residue levels in human breast milk from Vietnam were among the highest values reported for Asian developing countries as well as developed nations. This result suggests recent usage of DDTs in both north and south Vietnam. Interestingly, in both cities, the p,p'-DDT portion was higher in multiparas than those in primiparas. Considering the fact that the interval between the first and the second child of a mother in Vietnam is usually short, this result probably indicates continuous intake of DDTs in the population. Analysis of infant exposure to DDTs via breast milk suggested that the daily intake rates for number of individuals are close to or above the threshold for adverse effects which may raise concern on children health. - It is suggested that daily intake rates of persistent organochlorines in mothers in Vietnam may result in health risk for nursing children.

    Plastic solid waste has become a serious problem when considering the disposal alternatives following the sequential hierarchy of sound solid waste management. This study was undertaken to assess the quantity and composition of household solid waste, especially plastic waste to identify opportunities for waste recycling. A 1-month survey of 130 households was carried out in Can Tho City, the capital city of the Mekong Delta region in southern Vietnam. Household solid waste was collected from each household and classified into ten physical categories; especially plastic waste was sorted into 22 subcategories. The average household solid waste generation rate was 281.27 g/cap/day. The compostable and recyclable shares respectively accounted for high percentage as 80.74% and 11%. Regarding plastic waste, the average plastic waste generation rate was 17.24 g/cap/day; plastic packaging and plastic containers dominated with the high percentage, 95.64% of plastic waste. Plastic shopping bags were especially identified as the major component, accounting for 45.72% of total plastic waste. Relevant factors such as household income and household size were found to have an existing correlation to plastic waste generation in detailed composition. The household habits and behaviors of plastic waste discharge and the aspects of environmental impacts and resource consumption for plastic waste disposal alternatives were also evaluated.

    Land subsidence has become the most common hazard in urban area that could led to cracking buildings and infrastructures, extending the flooding area or even change the river path. Despite deriving precise information, conventional subsidence monitoring techniques are considered as costly, man-power consuming and lack of comprehensive information. Recently, SAR Interferometry (InSAR) has become a widely used geodetic technique for monitoring the deformation of the Earth's surface, especially methods based on the use of a multi-temporal dataset. In this study, we use a stack of 18 SAR images acquired from L-band PALSAR sensor onboard the ALOS satellite to derive the subsidence information of Ho Chi Minh city, Vietnam over the period of December 2006 to December 2010. The Stanford Method for Persistent Scatterers (StaMPS) Multi-Temporal Interferometry (MTI) approach is chosen to take advantages of both the persistent scatterers and the distributed scatterers, which could be used as monitoring points to measure the subsidence process. Assume the subsidence in this area mostly corresponds to vertical components, we found subsidence patterns along Saigon river and in the South of the city. Maximum subsidence rate reaches up to -66 mm/year in vertical direction. Finally, InSAR derived result and previous levelling data are taken into comparison to find the correlation between the two results.

    The results of (222)Rn and (226)Ra activity measurements in drinkable water supplies of the Thu Duc region in Ho Chi Minh City, Vietnam, are presented in this paper. The measurements were performed using a RAD 7 radon detector manufactured by Durridge Company, Inc. Mean concentrations of (222)Rn and (226)Ra were found to be 0.11±0.01Bql(-1) and 0.11±0.02Bql(-1) in 14 drinking water samples. They are 0.12±0.01Bql(-1) and 0.10±0.02Bql(-1) in 15 tap water samples, respectively. The mean (222)Rn concentration of 1.40±0.03Bql(-1) in the 20 groundwater samples of this study is also lower than the WHO advised level of 100Bql(-1). Fifty percent of groundwater samples analysed have (226)Ra levels in excess of the USEPA recommended maximum contaminant level of 0.185Bql(-1). The occurrence of elevated concentrations of (226)Ra in groundwater samples was explained by pH and alkaline conditions.

    In Vietnam, there is an emerging HIV epidemic among men who have sex with men (MSM). Male sex workers engage in high-risk sexual behaviours that make them particularly vulnerable to HIV infection. In 2010, 23 MSM in Ho Chi Minh City (HCMC) who recently received payment for sex with another man completed in-depth qualitative interviews exploring motivations for sex work, patterns of sex work disclosure and experiences of social stigma. Interviews were recorded, transcribed and translated into English and analysed using a qualitative descriptive approach. Low wages, unstable employment and family remittances were motivating factors for MSM in HCMC to sell sex. Participants described experiences of enacted and felt social stigma related to their involvement in sex work. In response, they utilised stigma management techniques aimed at concealment of involvement in sex work. Such strategies restricted sexual communication with non-paying sex partners and potentially limited their ability to seek social support from family and friends. Departing from decontextualized depictions of sex work disclosure, our findings describe how decisions to reveal involvement in sex work are shaped by social and structural factors such as social stigma, techniques to minimise exposure to stigma, economic imperatives and familial responsibilities.

    A three-year study that started solely as an industrial pollution reduction effort in Dong Nai Province of Vietnam expanded into an ongoing regional river basin water quality management effort. The project was a cooperative effort between the United Nations (UNDP and UNIDO) and the Federal and Provincial governments in Vietnam. A comprehensive approach was used to assess the impacts and strategies for reducing industrial, municipal and agricultural pollution to the water, air and land. The strategy was based upon use of knowledge in four subject areas, economics, ecology, technology and institutions, integrated within a framework for regional environmental quality management, sometimes called Areawide Environmental Quality Management (AEQM). Dong Nal Province encompasses a major developing area immediately north of Ho Chi Minh City. The land area chosen for the AEQM study is the 1,400 square kilometre region in and around Bien Hoa that drains into the Dong Nai River. The Dong Nai River serves many purposes including navigation, fisheries and a water supply for both the Province and Ho Chi Minh City. Extensive industrial and residential development was underway and was projected to increase in the coming decade. A strategy for the control of pollution from liquid, gaseous and solid wastes for the period 1998 to 2010 in Dong Nai Province was developed.

    Severe dioxin contamination at Bien Hoa and Da Nang airbases, Vietnam is of international concern. Public Health risk reduction programs were implemented in Bien Hoa in 2007-2009 and in Da Nang in 2009-2011. In 2009 and 2011 we reported the encouraging results of these interventions in improving the knowledge, attitude and practices (KAP) of local residents in reducing the dioxin exposure risk through foods. In 2013 we revisited these dioxin hot spots, aimed to evaluate whether the results of the intervention were maintained and to identify factors affecting the sustainability of the programs. To assess this, 16 in-depth interviews, six focus group discussions, and pre and post intervention KAP surveys were undertaken. 800 respondents from six intervention wards and 200 respondents from Buu Long Ward (the control site) were randomly selected to participate in the surveys. The results showed that as of 2013, the programs were rated as "moderately sustained" with a score of 3.3 out of 5.0 (cut off points 2.5 to <3.5) for Bien Hoa, and "well sustained" with a score of 3.8 out of 5.0 (cut off points 3.5 to <4.5) for Da Nang. Most formal intervention program activities had ceased and dioxin risk communication activities were no longer integrated into local routine health education programs. However, the main outcomes were maintained and were better than that in the control ward. Migration, lack of official guidance from City People's Committees and local authorities as well as the politically sensitive nature of dioxin issues were the main challenges for the sustainability of the programs.

    Ho Chi Minh City (HCMC) has become a fast growing city in recent decades and is still growing at a high pace. The water demand for more than 7 million people has increased tremendously, too. Beside surface water, groundwater is used in big amounts to satisfy the need of water. By now, more than 200,000 wells have been developed with very little control. To investigate the sustainability of the water abstraction, a model had been built for the HCMC area and its surrounding. On the catchment scale (around 24,000km2); however, many questions have remained unsolved. In this study, we first gathered and complied geological and hydrogeological information as well as data on groundwater quality to get an idea on regional groundwater flow pattern and problems related to the temporal change of the groundwater situation. Two problems have been depicted by this study. One is the construction of a water reservoir upstream of the Saigon River. This construction has probably changed the water table of the unconfined aquifer, and hence, has significantly changed the properties of soils in some areas. The other problem is the distribution of salty groundwater. Despite the distance of more than 40km from the seashore, groundwater from some wells in and around HCMC shows high concentrations of chloride. Several wells started to produce non-potable water. The chloride concentrations show a complicated and patchy distribution below HCMC, suggesting the possibility of the remnant saltwater at the time of sediment deposition. On the other hand, seawater invades along the streams far beyond HCMC during the dry season and this might be one of the possible sources of salty groundwater by vertical infiltration. A large-scale geological model was constructed and transformed into a hydrogeological model to better understand and quantify the groundwater flow system and the origin of saltwater. Based on the constructed model and numerical calculation, we discuss the influence of reservoir

    We report the coverage, safety, and logistics of a school-based typhoid fever immunization campaign that took place in Hue City, central Vietnam; a typhoid fever endemic area. A cluster-randomized evaluation-blinded controlled trial was designed where 68 schools (cluster) were randomly allocated the single dose Vi polysaccharide vaccine (Typherix) or the active control hepatitis A vaccine (Havrix). A safety surveillance system was implemented. A total of 32,267 children were immunized with a coverage of 57.5%. Strong predictors for vaccination were attending primary schools, peri-urban location of the school, and low family income. Human resources were mainly schoolteachers and the campaign was completed in about 1 month. Most adverse events reported were mild. Safe injection and safe sharp-waste disposal practices were followed. A typhoid fever school-based immunization campaign was safe and logistically possible. Coverage was moderate and can be interpreted as the minimum that could have been achievable because individual written informed consent procedures were sought for the first time in Hue City and the trial nature of the campaign. The lessons learned, together with cost-effectiveness results to be obtained by the end of follow-up period, will hopefully accelerate the introduction of Vi typhoid fever vaccine in Vietnam.

    Paragonimiasis is a food-borne parasitic zoonosis caused by infection with lung flukes of the genus Paragonimus. In Vietnam, research on Paragonimus and paragonimiasis has been conducted in northern and central regions of the country. Using a combination of morphological and molecular methods, 7 Paragonimus species, namely P. heterotremus, P. westermani, P. skrjabini, P. vietnamensis, P. proliferus, P. bangkokenis and P. harinasutai, have been identified in Vietnam. Of these, the first 3, P. heterotremus, P. westermani and P. skrjabini, are known to infect humans in other countries. However, in Vietnam, only P. heterotremus, found in some northern provinces, has been shown to infect humans. Even nowadays, local people in some northern provinces, such as Lai Chau and Yen Bai, are still suffering from P. heterotremus infection. In some provinces of central Vietnam, the prevalence and infection intensity of P. westermani metacercariae in freshwater crabs (the second intermediate hosts) are extremely high, but human cases have not been reported. Likewise, although P. skrjabini was found in Thanh Hoa Province, its pathogenicity to humans in Vietnam still remains uncertain. The results of molecular phylogenetic analyses of Vietnamese Paragonimus species provides new insights on the phylogeny and taxonomy of the genus Paragonimus. Comprehensive molecular epidemiological and geobiological studies on the genus in Vietnam and adjacent countries are needed to clarify the biodiversity and public health significance of the lung flukes.

    An emerging HIV epidemic can be seen among men who have sex with men (MSM) in Vietnam, with prevalence as high as 18%. Transactional sex represents a risk factor for HIV transmission/acquisition among MSM globally, particularly in urban contexts, but remains largely underinvestigated in Ho Chi Minh City (HCMC), Vietnam. In 2010, 23 MSM who reported exchanging sex for money in the last month completed a brief survey and semistructured qualitative interview at The Life Centre, a non-governmental organization in HCMC, to assess sociodemographics, individual- and structural-level HIV risk factors and explore acceptable future prevention interventions. Participants' mean age was 24 years. Equal proportions of respondents self-identified as heterosexual/straight, homosexual/gay, and bisexual. Participants had a mean of 158 male clients in the past year, with a median of 60 male clients in the past year (interquartile range [IQR]=70) and reported inconsistent condom use and inaccurate perceptions of HIV risk. Nearly half of the sample reported engaging in unprotected anal sex with a male partner in the past 12 months and one-third with a male client. Major themes that emerged for HIV prevention interventions with male sex workers were those that: (1) focused on individual factors (drug and alcohol use, barriers to condom use, knowledge of asymptomatic STIs, enhancement of behavioral risk-reduction skills, and addressing concomitant mental health issues); (2) incorporated interpersonal and relational contexts (led by peer educators, built interpersonal skills, attended to partner type and intimacy dynamics); and (3) considered the exogenous environments in which individual choices/relationships operate (stigma of being MSM in Vietnam, availability of alternative economic opportunities, and varied sexual venues). HIV prevention efforts are needed that address the specific needs of MSM who engage in transactional sex in HCMC. Universally, MSM endorsed HIV prevention

    Two members of the Paragonimus skrjabini complex, P. skrjabini and P. miyazakii, are now considered as two sub-species, P. skrjabini skrjabini and P. skrjabini miyazakii. They are well known as important pathogens for human paragonimiasis in China and Japan. Recently, members of this species complex have been reported from India. Here we report the first discovery of P. skrjabini from freshwater crab hosts in Thanh Hoa province, Vietnam. For morphological and molecular phylogenetic studies, adult worms were obtained by experimental infection in cats and dogs. Molecular analyses of metacercariae and adults revealed that the P. skrjabini population from Thanh Hoa, Vietnam was almost completely identical with that from Yunnan province, China. Those populations from Thanh Hoa, Vietnam and Yunnan, China and those from Manipur, India were significantly different from P. skrjabini populations reported from other localities of China in cytochrome oxidase subunit 1 (CO1) gene sequences, indicating considerable genetic variation within the P. skrjabini complex. Moreover, low bootstrap values in the CO1 tree suggested that more variant genotypes belonging to P. skrjabini complex may be found in other Asian countries in between Vietnam and India, such as Myanmar, Laos and Thailand. Since P. skrjabini is known as a pathogen for humans, paragonimiasis cases caused by P. skrjabini might be found in Vietnam and other Asian countries.

    Injection drug use is a major factor in acquiring and transmitting HIV in Vietnam. This analysis aims to present estimates of HIV infection and factors associated with HIV infection among female sex partners (FSP) of MWID in Ho Chi Minh City (HCMC), Vietnam. Cross-sectional surveys were conducted in 2011 and 2013 among males who inject drugs (MWID) who then referred their FSP for a behavioral and biologic survey. In total, 445 MWID and FSPs were enrolled. HIV prevalence among MWID was 50 and 35 % among FSPs. Among FSPs, 60.3 % reported ever using illegal drugs and among those, 72.7 % reported ever injecting illicit drugs. Among FSP, injection drug for >1 year [adjusted Odds Ratio (aOR), 95 % CI 2.94, 1.19-7.26), p value = <0.001] and having a male partner infected with HIV [(aOR 3.35: 1.97-5.69), p value = <0.001] were associated with HIV infection. The prevalence of HIV infection is high among FSP of MWID in HCMC and is highly associated with the injection drug use behavior of the FSP. Harm-reduction intervention programs that focus on the MWID-FSP couple or directly on the FSPs are required.

    This study used a confidential survey method-namely, Audio Computer-Assisted Self-Interview (ACASI)-to gather data about HIV-related risk knowledge/behaviors among the general population in Vietnam. The study sample included 1371 people aged 15 to 49 years in 3 cities-Hanoi, Da nang, and Can Tho. Results indicated that 7% of participants had ever had nonconsensual sex, and 3.6% of them had ever had a one-night stand. The percentage of male participants reported to ever have sex with sex workers was 9.6% and to ever inject drugs was 4.3%. The proportion of respondents who had ever tested for HIV was 17.6%. The risk factors and attitudes reported in the survey indicate the importance of analyzing risk behaviors related to HIV infection among the general population. Young people, especially men in more urbanized settings, are engaging in risky behaviors and may act as a "bridge" for the transmission of HIV from high-risk groups to the general population in Vietnam.

    Concurrent infection with multiple types of Human Papillomavirus (HPV) is associated with an increased risk of cervical cancer; yet, little is known about risk factors for concurrent HPV infection in Vietnam. This study investigated the prevalence of and risk factors for high-risk-type HPV and multi-type HPV infections among women in Ho Chi Minh City, Vietnam. Data were collected from a population-based survey of 1,550 women (mean age = 42.4; SD = 9.5), using a multi-stage sampling process. Socio-demographic and behavioral variables were obtained by self-report. HPV genotypes in cervical specimens were identified using PCR protocols. The prevalence of any high-risk HPV infection was 9.0%, and of multi-type HPV infection was 1.9%. In the HPV+ subsample, the percentage of high-risk HPV was 84% and of multi-type HPV was 20%. All multi-type HPV infections were high-risk-type. Lifetime smoking and older age of first sex were significantly associated with any high-risk and multi-type HPV infections. Regular condom use was inversely associated with high-risk and multi-type HPV infection. Risk factors for high-risk and multi-type HPV infections were similar. Further research and intervention are needed to reduce HPV infections in order to prevent HPV-related cancers.

    Surgical site infections (SSIs) are the most common healthcare-associated infections (HAI) in lower-income countries. This is the first study to report the results of surveillance on SSI stratified by surgical procedure in seven Vietnamese cities. This was a prospective, active SSI surveillance study conducted from November 2008-December 2010 in seven hospitals using the U.S. Centers for Disease Control and Prevention's National Healthcare Safety Network (CDC-NHSN) definitions and methods. Surgical procedures (SPs) were classified into 26 types according to the International Classification of Diseases Edition 9 criteria. We recorded 241 SSIs, associated with 4,413 SPs (relative risk [RR] 5.5%; 95% confidence interval [95% CI] 4.8-6.2). The highest SSI rates were found for limb amputation (25%), colon surgery (33%), and small bowel surgery (21%). Compared with CDC-NHSN SSI report, our SSI rates were higher for the following SPs: Limb amputation (25% vs. 1.3%; RR 20.0; p = 0.001); appendix surgery (8.8% vs. 3.5%; RR 2.54; 95% CI 1.3-5.1; p = 0.001); gallbladder surgery (13.7% vs. 1.7%; RR 7.76; 95% CI 1.9-32.1; p = 0.001); colon surgery (18.2% vs. 4.0%; RR 4.56; 95% CI 2.0-10.2; p = 0.001); open reduction of fracture (15.8% vs. 3.4%; RR 4.70, 95% CI 1.5-15.2; p = 0.004); gastric surgery (7.3% vs. 1.7%; RR 4.26; 95% CI 2.2-8.4, p = 0.001); kidney surgery (8.9% vs. 0.9%; RR 10.2; 95% CI 3.8-27.4; p = 0.001); prostate surgery (5.1% vs. 0.9%; RR 5.71; 95% CI 1.9-17.4; p = 0.001); small bowel surgery (20.8% vs. 6.7%; RR 3.07; 95% CI 1.7-5.6; p = 0.001); thyroid or parathyroid surgery (2.4% vs. 0.3%; RR 9.27; 95% CI 1.0-89.1; p = 0.019); and vaginal hysterectomy (14.3% vs. 1.2%; RR 12.3; 95% CI 1.7-88.4; p = 0.001). Our SSIs rates were significantly higher for 11 of the 26 types of SPs than for the CDC-NHSN. This study advances our knowledge of SSI epidemiology in Vietnam and will allow us to introduce targeted interventions.

  8. Analyzing Drought Adaptation Practices of Sugarcane Growers in Thanh Cong, Thach Thanh District, Thanh Hoa, Vietnam

    Nguyen, GTH.

    2016-01-01

    Full Text Available Embedded in a package of climate change adaptation, researchers and farmers tested the melon hybrid variety, Kim Hoang Hau (KHH, for yield and disease resistance during the spring-summer season from March to June 2015 in Giao Thuy district, Nam Dinh province. The results were analysed and subsequently discussed with local farmers in focused groups. Analysis showed that the KHH was suitable to local soil conditions. The farmers preferred this new variety over the local melon, because not only did KHH give higher yield and pest resistance, it also showed less vulnerability to climatic stressors. Farmers decided to grow KHH based on the prevailing good market price at that time. However, farmers only shifted away from the old melon when they could anticipate the possibility of selling the new product. Those who did not continue with the KHH had difficulty in actively accessing the market for this new product. This study suggests that the market information does not solely drive the process of the adaptation itself, but it also provides relevant stimuli to farmers enabling them to successfully shift to new crop varieties. This study also implies that such process-based understanding is crucial in formulating strategies that increase the farmer's capacity to adapt to climate change.

  9. Generating Bijections between HOAS and the Natural Numbers

    2010-01-01

    A provably correct bijection between higher-order abstract syntax (HOAS) and the natural numbers enables one to define a "not equals" relationship between terms and also to have an adequate encoding of sets of terms, and maps from one term family to another. Sets and maps are useful in many situations and are preferably provided in a library of some sort. I have released a map and set library for use with Twelf which can be used with any type for which a bijection to the natural numbers exists. Since creating such bijections is tedious and error-prone, I have created a "bijection generator" that generates such bijections automatically together with proofs of correctness, all in the context of Twelf.

    Although a growing body of evidence suggests that low dead space syringes may reduce the risk of human immunodeficiency virus (HIV) and Hepatitis C virus infection associated with sharing syringes among people who inject drugs, there is little evidence of effective approaches to motivate people who inject drugs (PWID) to shift from high to low dead space syringes. Using a mix of consumer and trade marketing approaches, informed by rapid assessments of both the syringe market and PWID preferences, practices, and behaviors in Hanoi and Ho Chi Minh City, Population Services International (PSI) Vietnam piloted an intervention to increase the use of low dead space syringes (LDSS) in the three provinces of Hanoi, Ho Chi Minh City, and Thai Nguyen, where an estimated 31% of PWID are HIV positive and 58% are living with hepatitis C virus (HCV). This paper provides a summary of the social marketing activities implemented and results achieved by PSI Vietnam during an initial 1-year pilot period from December 2012 to December 2013 in these three provinces to explore their effectiveness in motivating PWID to use low dead space syringes. We found major increases in sales of LDSS accompanied by increases in reported use and consistent use of LDSS among PWID in the three provinces included in the pilot program and a positive and independent association (odds ratio (OR) 21.08; 95% confidence interval (CI) 10.6-27.3) between LDSS use and exposure to social marketing activities. We also found that LDSS use had a stronger association with perceptions of LDSS product quality than with perceptions regarding LDSS potential to reduce HIV transmission risk and use. We conclude that social marketing interventions have an important role to play in widening access to and the use of LDSS for PWID, as they address the need for PWID to find LDSS when and where they need them and also promote the benefits of LDSS use to PWID. High coverage of these activities among PWID appears to be the key in

    2013-01-01

    Early evidence shows that amphetamine-type stimulant (ATS) use has been rapidly increasing in Vietnam. Female sex workers (FSWs) who use ATSs have increased sexual risks for HIV infection. This paper presents qualitative data from a mixed-method study conducted from 2010 to 2011 that aimed to explore the use of ATS among FSWs in three major cities and to identify HIV-related sexual risks among this group. A total of 37 in-depth interviews were conducted, and thematic analysis was performed using NVIVO 8.0 software. Study participants reported that they perceive ATS to be more 'stylish', 'higher class' and much less 'addictive' than heroin. The study highlights multiple sexual risks among this group, including having prolonged sex; sex with multiple simultaneous partners or clients; lack of negotiation for safe sex; increased likelihood of group sex in the context of drug pooling and extended drug and sexual network; as well as unprotected sex. There is an urgent need to promote contextually appropriate interventions to reduce the HIV-related sexual risks among this group.

    Objectives This study aimed to examine the relationship between self-reported oral health, oral hygiene practices, and oral human papillomavirus (HPV) infection among women at risk for sexually transmitted infections in Ho Chi Minh City, Vietnam. Study design Convenience and referral sampling methods were used in a clinic-based setting to recruit 126 women aged 18–45 years between August–October 2013. Behavioral factors were self-reported. Oral-rinse samples were tested for HPV DNA of two low-risk and 13 high-risk genotypes. Results A higher unadjusted prevalence of oral HPV infection was associated with poorer self-rated overall oral health (p=.001), reporting oral lesions/problems in the past year (p=.001), and reporting a tooth loss not because of injury (p=.001). Higher unadjusted prevalence of oral HPV infection was also associated with two measures of oral hygiene: lower frequencies of toothbrush per day (p=.047) and gargling without toothbrush (p=.037). After adjusting for other factors in multivariable logistic regression models, poorer self-rated overall oral health remained statistically associated with oral HPV infection (p=.042); yet, the frequency of toothbrush per day did not (p=.704). Conclusion Results corroborate the association between self-reported poor oral health and oral HPV infection. The effect of oral hygiene on oral HPV infection remains inconclusive. PMID:26093681

    This paper discusses the impacts of gender norms on the sexual life and experience of a group of young Vietnamese people. It is based on a qualitative study on sexuality and abortion among young people in Ho Chi Minh City, Vietnam. There were two general attitudes towards premarital sex. One view supported young people in a serious, loving relationship engaging in sex before marriage; the other opposed premarital sex because it affected the reputation of girls and their families. These general attitudes were similar to the views on virginity: one group believed strongly in girls maintaining their virginity and the other group emphasised love, emotion and trust, not virginity, as the most important criteria for marriage. Among women there were more supporters than opponents of the traditional view of premarital sex and virginity. Premarital sex was more acceptable for young people in a serious, loving relationship with certain commitment to marriage. Young men considered sex a way to express their love and to become more intimate. Women's view was that premarital sex only occurred within a serious, loving relationship or when there was a serious commitment to marriage. It is clear that young people's sexual life is shaped and constrained by gender norms through political interventions, sexual education and moral judgements. Under the pressure of these norms, young people face many difficulties in order to fulfill a safe and satisfying sexual life.

    Full Text Available BACKGROUND: In Vietnam, men who have sex with men (MSM are highly affected by HIV and need new targeted HIV prevention strategies. OBJECTIVES: To assess the willingness to use the Internet to seek information on HIV prevention and care and associated factors among MSM in Ho Chi Minh City. METHODS: A descriptive cross-sectional study was conducted in 2012. Participants were recruited using a convenience sampling method in venues most frequented by MSM and completed a self-administered questionnaire. Logistic regression models were performed to estimate factors associated with the willingness to use the Internet to seek information on HIV prevention and care. RESULTS: A total of 358 MSM were approached for the survey and 222 questionnaires (62.0% were eligible for analyses. Overall, 76.1% of the respondents reported that they were willing to use the Internet to seek information on HIV prevention and care. A number of male partners in last year less than or equal to 3 (Adjusted Odds Ratio: 3.07, 95% Confidence interval: 1.40-6.73, a history of STI screening (4.10, 1.02-16.48 and HIV testing (3.23, 1.20-8.64 and having ever sought a male sexual partner through the Internet (3.56, 1.55-8.18 were significantly positively associated with the willingness to use the Internet to seek information on HIV prevention and care. CONCLUSION: The MSM interviewed in Ho Chi Minh City reported a high willingness to use the Internet to seek information on HIV prevention and care. In a context where new media are increasingly considered as promising options for reaching this HIV risk group, further research should be conducted on developing and testing tailored online tools adapted to the needs of Vietnamese MSM.

    Sarcophaga flexuosa Ho, 1934 is the type species of the currently monotypic genus-group taxon Hoa Rohdendorf, 1937, which here is considered a subgenus of Sarcophaga Meigen, 1826. Using DNA sequences of mitochondrial genes (cytochrome oxidase I and cytochrome b), we positively identify, for the first time, the female of S. (H.)flexuosa. The female is described, the male is redescribed, and both sexes are illustrated using a combination of line drawings, photographs and scanning electron microscopy images. It is argued from the morphology of the male terminalia that Sarcophagaflexuosa is the sister taxon of Sarcophaga basiseta Baranov, 1931, and the subgenus Hoa is redefined to include both of these species.

    Full Text Available Many urban areas experience both fluvial and pluvial floods, because locations next to rivers are preferred settlement areas, and the predominantly sealed urban surface prevents infiltration and facilitates surface inundation. The latter problem is enhanced in cities with insufficient or non-existent sewer systems. While there are a number of approaches to analyse either fluvial or pluvial flood hazard, studies of combined fluvial and pluvial flood hazard are hardly available. Thus this study aims at the analysis of fluvial and pluvial flood hazard individually, but also at developing a method for the analysis of combined pluvial and fluvial flood hazard. This combined fluvial-pluvial flood hazard analysis is performed taking Can Tho city, the largest city in the Vietnamese part of the Mekong Delta, as example. In this tropical environment the annual monsoon triggered floods of the Mekong River can coincide with heavy local convective precipitation events causing both fluvial and pluvial flooding at the same time. Fluvial flood hazard was estimated with a copula based bivariate extreme value statistic for the gauge Kratie at the upper boundary of the Mekong Delta and a large-scale hydrodynamic model of the Mekong Delta. This provided the boundaries for 2-dimensional hydrodynamic inundation simulation for Can Tho city. Pluvial hazard was estimated by a peak-over-threshold frequency estimation based on local rain gauge data, and a stochastic rain storm generator. Inundation was simulated by a 2-dimensional hydrodynamic model implemented on a Graphical Processor Unit (GPU for time-efficient flood propagation modelling. All hazards – fluvial, pluvial and combined – were accompanied by an uncertainty estimation considering the natural variability of the flood events. This resulted in probabilistic flood hazard maps showing the maximum inundation depths for a selected set of probabilities of occurrence, with maps showing the expectation (median

    Urban climate, one of the challenges of human being in 21 century, is known as the results of land use/cover transformation. Its characteristics are distinguished by different varieties of climatic conditions in comparison with those of less built-up areas. The alterations lead to "Urban Heat Island", in which temperature in urban places is higher than surrounding environment. This happens not only in mega cities but also in less urbanized sites. The results determine the change of land use/cover and land surface temperature in Danang city by using multi-temporal Landsat and ASTER data for the period of 1990-2009. Based on the supervised classification method of maximum likelihood algorithm, satellite images in 1990, 2003, 2009 were classified into five classes: water, forest, shrub, agriculture, barren land and built-up area. For accuracy assessment, the error metric tabulations of mapped classes and reference classes were made. The Kappa statistics, derived from error matrices, were over 80% for all of land use maps. An comparison change detection algorithm was made in three intervals, 1990-2003, 2003-2009 and 1990-2009. The results showed that built-up area increased from 8.95% to 17.87% between 1990 and 2009, while agriculture, shrub and barren decreased from 12.98% to 7.53%, 15.72% to 9.89% and 3.88% to 1.77% due to urbanization that resulted from increasing of urban population and economic development, respectively. Land surface temperature (LST) maps were retrieved from thermal infrared bands of Landsat and ASTER data. The result indicated that the temperature in study area increased from 39oC to 41oC for the period of 1990-2009. Our analysis showed that built-up area had the highest LST values, whereas water bodies had the least LST. This study is expected to be useful for decision makers to make an appropriate land use planning which can mitigate the effect to urban climate.

    The "June 27th" flow, named for the date on which it started, threatened communities on the lower East Rift Zone (ERZ) of Kīlauea Volcano, Hawaii, for several months during 2014-2015. The flow encroached on Pāhoa, threatening to cross the main street and sever Highway 130, which serves the rural communities on Kīlauea's south and east flanks. The rate of flow advance was influenced greatly by magma supply from the summit. Increases in ERZ discharge, presaged by inflationary summit tilt, resulted in flow advance of up to several hundred meters per day. When summit tilt switched to deflation, discharge waned and the flow slowed and often stalled, repeatedly stopping short of destroying critical infrastructure. When activity resumed, it typically did so as many small breakouts as far as a few km behind the flow front, which then had to resurface previously covered ground to extend the overall length of the flow. At the same time, lava near the flow front had a very spiny texture and was noticeably less fluid than lava closer to the vent, leading to speculation that physiochemical changes along the flow were limiting its length. In December 2014, we collected a suite of lava samples along the flow from near Pu`u `Ō`ō to its distal end (3 km to 18 km) to better understand the physiochemical changes along its length. The magma flux on that day was calculated at 90,000- 100,000 m3/day (~1 m3/s). Preliminary analyses of the samples reveal a down-flow decrease in lava vesicularity and temperature and a corresponding increase in density and microcrystallinity. We propose that the lava flow could only attain a length of ~21 km because of the changes in its apparent viscosity, for the calculated magma flux. The flows could not overcome the increasing downstream yield strength, and breakouts from the flow margins farther upslope were easier to achieve than forcing the front forward. These upslope breakouts were themselves limited in length by the same factors.

  5. Backyard Living – Integrative Policies Towards Migrant Workers: Housing Microfinance in Greater Ho Chi Minh City, Vietnam

    Full Text Available The urban agglomeration of the Vietnamese southeast industrial driving force Ho Chi Minh City (HCMC has become the most outstanding benefi ciary of the remarkable economic growth and foreign investments in the Vietnamese economy since the start of a comprehensive economic reform process in the mid 1980s. The notable development towards the foremost economic centre led to a high influx of migrant workers. In the course of an ongoing expansion process towards a megacity of tomorrow, the defi cient provision of adequate housing remains one of the most challenging problems of rural migrants in Greater HCMC. However, a future-oriented sustainable megacity concept is strongly dependent on the successful integration of migrants into the urban society. Within this context, the housing market is considered to be a key aspect of comprehensive urban planning. Hereby, housing microfinance (HMF will be presented as an alternative housing finance scheme meeting the demand of a noteworthy number of poor and low-income people. Thereby HMF can do both: focus on specifi c needs of migrants with respect to their current life situation and enhance its outreach to a potential target group.

    As one of the most ordinary phenomena in nature, numerous pores on animal skins induce the growth of abundant hairs. In this study, cavities of a cellulose matrix were used as hard templates to lead the hair-inspired crystal growth of 12-hydroxyoctadecanoic acid (HOA) through hydrophobic-hydrophilic interface interaction, and short hair-like HOA crystals with a smooth surface were formed on cellulose films. In our findings, by using solvent evaporation induced crystallization, hydrophobic HOA grew along the hydrophilic cellulose pore wall to form regular vertical worm-like and pillar-like crystals with an average diameter of about 200 nm, depending on the experimental conditions and HOA concentration. The formation mechanism of the short hair-like HOA crystals as well as the structure and properties of the cellulose/HOA submicrometer composite films were studied. The pores of the cellulose matrix supplied not only cavities for the HOA crystals fixation but also hydrophilic shells to favor the vertical growth of the relatively hydrophobic HOA crystals. The cellulose/HOA submicrometer composite films exhibited high hydrophobicity, as a result of the formation of the solid/air composite surface. Furthermore, 4-(1,2,2-triphenylethenyl) benzoic acid, an aggregation-induced emission luminogen, was used to aggregate on the cellulose surface with HOA to emit and monitor the HOA crystal growth, showing bifunctional photoluminscence and self-cleaning properties. This work opens up a novel one-step pathway to design bio-inspired submicrometer materials by utilizing natural products, showing potential applications in self-cleaning optical devices.

    Spatial repellency of metofluthrin-impregnated polyethylene latticework plastic strips against Aedes aegypti mosquitoes was evaluated. Analysis of environmental factors affecting the efficacy of these strips, such as room temperature, humidity, and house structure, was performed in a residential area in My Tho City, Tien Giang Province, Vietnam. Treatment with the strips at the rate of 1 strip per 2.6-5.52 m(2) (approximately 600 mg per 2.6-5.52 m(2)) reduced the collection of Ae. aegypti resting inside the houses for at least eight weeks. Multiple regression analysis indicated that both increase in the average room temperature and decrease in the area of openings in the rooms that were treated with the strips positively affected the spatial repellency of metofluthrin.

    Vietnam has experienced fast growth in energy consumption in the past decade, with annual growth rate of over 12 percent. This is accompanied by the fast increase in commercial energy use, driven by rapid industrialization, expansion of motorized transport, and increasing energy use in residential and commercial buildings. Meanwhile, Vietnam is experiencing rapid urbanization at a rate of 3.4 percent per year; and the majority of the growth centered in and near major cities such as Hanoi and Ho Chi Minh City. This has resulted in a construction boom in Vietnam.

    2012-06-01

    There is emerging evidence, largely from studies in Europe and North America, that economic deprivation increases the magnitude of morbidity and mortality related to air pollution. Two major reasons why this may be true are that the poor experience higher levels of exposure to air pollution, and they are more vulnerable to its effects--in other words, due to poorer nutrition, less access to medical care, and other factors, they experience more health impact per unit of exposure. The relations among health, air pollution, and poverty are likely to have important implications for public health and social policy, especially in areas such as the developing countries of Asia where air pollution levels are high and many live in poverty. The aims of this study were to estimate the effect of exposure to air pollution on hospital admissions of young children for acute lower respiratory infection (ALRI*) and to explore whether such effects differed between poor children and other children. ALRI, which comprises pneumonia and bronchiolitis, is the largest single cause of mortality among young children worldwide and is responsible for a substantial burden of disease among young children in developing countries. To the best of our knowledge, this is the first study of the health effects of air pollution in Ho Chi Minh City (HCMC), Vietnam. For these reasons, the results of this study have the potential to make an important contribution to the growing literature on the health effects of air pollution in Asia. The study focused on the short-term effects of daily average exposure to air pollutants on hospital admissions of children less than 5 years of age for ALRI, defined as pneumonia or bronchiolitis, in HCMC during 2003, 2004, and 2005. Admissions data were obtained from computerized records of Children's Hospital 1 and Children's Hospital 2 (CH1 and CH2) in HCMC. Nearly all children hospitalized for respiratory illnesses in the city are admitted to one of these two pediatric

    Optical and crystal-chemical changes in two beryl varieties after the heat treatment were determined using a wide spectrum of analytical methods. Studied aquamarines are generally more enriched in Fe (up to 0.25 apfu) and alkali (up to 0.08 apfu) than yellow beryls (up to 0.07 apfu Fe, up to 0.04 apfu alkali). The determined c/ a ratio of 0.997-0.998 classified all our studied beryls as "normal" beryls. While no crystal structure changes were observed in samples heated to 700 °C, those heated to 900 and 1,100 °C exhibited cracks and fissures. Reduced Fe occurred in samples heated between 300 and 700 °C, and subsequent oxidation from 900 to 1,100 °C induced changes in their colour and clarity. The Fe-bearing beryl colour is controlled by the position of the absorption edge and the presence of a broad band attributed to Fe2+ in the NIR region. Blue colour results from the absorption edge located deeper in the UV region and the presence of broad band in the NIR region. Shift of absorption edge to the visible region at the presence of the broad band gives a yellow colour. Although our studied beryls are enriched in H2O I molecule due to their low alkali content, the H2O II molecule is also present. The following two dehydration processes were observed: (1) release of one double-coordinating H2O II molecule at 300-500 °C and (2) total dehydration at 900-1,100 °C. The observed cracks and fissures likely resulted from channel water release in large beryl crystals.

    Little information is available on the epidemiology of Giardia duodenalis in beef cattle from Vietnam. This study was performed to determine the prevalence and genotypes/assemblages of G. duodenalis in native beef calves younger than 6 months in the region. A total of 412 calf fecal samples, randomly selected from 99 small-scale farms located in DacLac and KhanhHoa provinces, central Vietnam, were screened for the presence of G. duodenalis cysts using the zinc-sulfate flotation method followed by iodine staining. The overall prevalence on the sample and herd levels were 13.8% (57/412) and 42.4% (42/99), respectively. Molecular analysis in the β-giardin and triosephosphate isomerase genes demonstrated the presence of only G. duodenalis assemblage E in the animals. Since assemblage E has been rarely reported in humans, the zoonotic risk in beef calves in the region appears to be minimal.

    Full Text Available Vermicomposting technique in South Vietnam. Earthworms play a major role in organic matter transformation. The vermicomposting allows to combine several advantages: the management of diversified organic wastes, and the production of earthworms and vermicompost. Crop residues and other plant wastes mixed with animal manure from individual farms can be used. In South Vietnam, farmers are rearing some livestock and growing a few number of crop species. From several years, an increasing number of vermicomposting units were set in many farms from the Ho Chi Minh City region. Two kinds of infrastructure materials are used: baked clay blocks or bamboo stems with plastic covers. In South Vietnam, all conditions are pooled to ensure an efficient earthworm production: suitable climate, available organic wastes and materials to build the vermicomposting structures. Both field plot fertility and protein feed for livestock (pigs, poultry, etc. can be provided by rearing earthworms.

    Full Text Available This is a qualitative designed and conducted with two primary research aims, which were: 1 To study the life and experiences of symphonic orchestra conductors in Hanoi, Vietnam; 2 To study the inheritance process for conductors of the symphonic orchestra in Hanoi, Vietnam. The research area for this investigation was purposively selected as the Vietnam National Academy of Music in Hanoi. The investigation began in October 2012 and was concluded in January 2014. The two key informants for this investigation were expert conductors and teachers at the academy, Dr. Nguyễn Phúc Linh and Dr. Nguyễn Thiếu Hoa. Data was collected from a combination of document analysis and field research. Tools used for data collection included interviews, participant and non-participant observation and focus group discussions. Results show that both of the key informants for this investigation were born into families of artists and had a particularly close relationship with traditional folk art. Scholarships to study abroad at the Tchaikovsky University, Russia enabled them to learn from Russian conductors and they developed the skills that have now led them to be recognized as being among the most accomplished conductors in Vietnam. The process of instruction preferred by these two academics is taught in three steps: the preparation stage, the teaching stage and the assessment and evaluation stage. The benefits of studying with Dr. Nguyễn Phúc Linh and Dr. Nguyễn Thiếu Hoa are the cumulative experiences of international conducting practices and the high standards that the two academics possess and demand.

    2015-09-01

    The system HoA l3(BO3) 4 has recently been found to exhibit a large magnetoelectric effect. To understand the mechanism, macroscopic and atomic level properties of HoA l3(BO3) 4 were explored by temperature and magnetic field dependent heat capacity measurements, pressure and temperature dependent x-ray diffraction measurements, as well as temperature and magnetic field dependent x-ray absorption fine structure measurements. The experimental work was complemented by density functional theory calculations. An anomalous change in the structure is found in the temperature range where large magnetoelectric effects occur. No significant structural change or distortion of the Ho O6 polyhedra is seen to occur with magnetic field. However, the magnetic field dependent structural measurements reveal enhanced correlation between neighboring Ho O6 polyhedra. This observed response is seen to saturate near 3 T. A qualitative atomic level description of the mechanism behind the large electric polarization induced by magnetic fields in the general class of RA l3(BO3) 4 systems (R = rare earth) is developed.

The reason is largely Vietnam’s historical experiences from the aid relationship with the Soviet Union, which created dependence and eventually an economic crisis when aid flows dried up in the late 1980s. Instead, there has been substantial tension between the donor community and Vietnam...... towards Vietnam. However, it is likely that the antidumping measures used by the EU are not primarily directed at Vietnam, but rather at China.

    Full Text Available The Cat Ba National Park area (Vietnam with its tropical forest is recognized as being part of the world biodiversity conservation by the United Nations Educational, Scientific and Cultural Organization (UNESCO and is a well-known destination for tourists, with around 500,000 travelers per year. This area has been the site for many research projects; however, no project has been carried out for forest fire susceptibility assessment. Thus, protection of the forest including fire prevention is one of the main concerns of the local authorities. This work aims to produce a tropical forest fire susceptibility map for the Cat Ba National Park area, which may be helpful for the local authorities in forest fire protection management. To obtain this purpose, first, historical forest fires and related factors were collected from various sources to construct a GIS database. Then, a forest fire susceptibility model was developed using Kernel logistic regression. The quality of the model was assessed using the Receiver Operating Characteristic (ROC curve, area under the ROC curve (AUC, and five statistical evaluation measures. The usability of the resulting model is further compared with a benchmark model, the support vector machine (SVM. The results show that the Kernel logistic regression model has a high level of performance in both the training and validation dataset, with a prediction capability of 92.2%. Since the Kernel logistic regression model outperforms the benchmark model, we conclude that the proposed model is a promising alternative tool that should also be considered for forest fire susceptibility mapping in other areas. The results of this study are useful for the local authorities in forest planning and management.

    2012-04-01

    In many developing countries water is a key renewable resource to complement carbon-emitting energy production and support food security in the face of demand pressure from fast-growing industrial production and urbanization. To cope with undergoing changes, water resources development and management have to be reconsidered by enlarging their scope across sectors and adopting effective tools to analyze current and projected infrastructure potential and operation strategies. In this work we use multi-objective deterministic and stochastic optimization to assess the current reservoir operation and planned capacity expansion in the Red River Basin (Northern Vietnam), focusing on the major controllable infrastructure in the basin, the HoaBinh reservoir on the Da River. We first provide a general and mathematical description of the socio economic and physical system of the Red River Basin, including the three main objectives of hydropower production, flood control, and water supply, and using conceptual and data-driven modeling tools. Then, we analyze the historical operation of the HoaBinh reservoir and explore re-operation options corresponding to different tradeoffs among the three main objectives, using Multi-Objective Genetic Algorithm. Results show that there exist several operating policies that prove Pareto-dominant over the historical one, that is, they can improve all three management objectives simultaneously. However, while the improvement is rather significant with respect to hydropower production and water supply, it is much more limited in terms of flood control. To understand whether this is due to structural constraints (insufficient storing capacity) or to the imperfect information system (uncertainty in forecasting future flows and thus anticipate floods), we assessed the infrastructural system potential by application of Deterministic Dynamic Programming. Results show that the current operation can only be relatively improved by advanced optimization

    Disability is shown to be both a cause and a consequence of poverty. However, relatively little research has investigated the economic cost of living with a disability. This study reports the results of a study on the extra cost of living with disability in Vietnam in 2011. The study was carried out in eight cities/provinces in Vietnam, including Hanoi and Ho Chi Minh cities (two major metropolitan in Vietnam) and six provinces from each of the six socio-economic regions in Vietnam. Costs are estimated using the standard of living approach whereby the difference in incomes between people with disability and those without disability for a given standard of living serves as a proxy for the cost of living with disability. The extra cost of living with disability in Vietnam accounted for about 8.8-9.5% of annual household income, or valued about US$200-218. Communication difficulty was shown to result in highest additional cost of living with disability and self-care difficulty was shown to lead to the lowest levels of extra of living cost. The extra cost of living with disability increased as people had more severe impairment. Interventions to promote the economic security of livelihood for people with disabilities are needed.

    Full Text Available Fasciola spp. were collected from naturally infected cattle at a local abattoir of Khanh Hoa province, Vietnam, for morphological and genetic investigations. Microscopic examination detected no sperm cells in the seminal vesicles, suggesting a parthenogenetic reproduction of the flukes. Analyses of sequences from the first and second internal transcribed spacers (ITS1 and ITS2 of the ribosomal RNA revealed that 13 out of 16 isolates were of Fasciola gigantica type, whereas three isolates presented a hybrid sequence from F. gigantica and Fasciola hepatica. Interestingly, all the mitochondrial sequences (partial COI and NDI were of F. gigantica type, suggesting that the maternal lineage of the hybrid form is from F. gigantica. No intra-sequence variation was detected.

    Seagrass beds and coral reefs are two important ecosystems in the coastal zone. They play an important role to protect and shelter various marine organisms. Both seagrass beds and coral reefs could prevent the coastline from erosion. While seagrass stabilizes sediments and acts as a biofilter, coral reefs can control carbon dioxide in the ocean water. Besides, seagrass also provides direct food for many fish and marine animals. Therefore, mapping seagrass beds and coral reefs is very important for coastal management and conservation. In May 2013, Vietnam launched the first satellite for earth observations, called Vietnam Natural Resources, Environment and Disaster Monitoring Satellite (VNREDSAT-1). It is a great opportunity for environmental monitoring in the country using the data from this satellite. The objective of this study is to use the VNREDSAT-1 data to map seagrass beds and coral reefs in the coastal region of Ninh Hai district, Ninh Thuan province, Vietnam, where the seagrass still remains in good a condition. We processed the VNREDSAT-1 image through four steps: (1) Atmospheric correction using Second Simulation of the Satellite Signal in the Solar Spectrum radiative transfer model (6S), (2) Sun glint removal by using Hedley method, (3) Water column correction using the depth-variant index (DII) proposed by Lyzenga, and (4) Image classification using the maximum likelihood algorithm. The mapping results verified with the ground reference data showed a good overall accuracy of 75% and Kappa coefficient of 0.7. The total area of seagrass beds was approximately 323.09 ha, which mainly distributed in My Hoa and Thai An villages. The total area of coral reefs was approximately 564.42 ha, located along the coast and on outer area to seagrass and shoreline reefs. This study demonstrates the applicability of VNREDSAT-1 for underwater habitat monitoring. The results could be useful for natural resources managers to devise strategies for management and

    Background The metabolic syndrome (MS) is characterized by a specific clustering of risk factors, including dyslipidemia, central adiposity, systemic hypertension, insulin resistance, and dysglycemia. It is associated with an increased risk of developing cardiovascular disease (CVD). Accurate data on prevalence and characteristics of MS will facilitate the development of preventive strategies for CVD. Objective To estimate accurately the prevalence of MS among Vietnamese adults with the usual criteria or with the criteria modified for Asian populations. Design and methods We studied a representative, cross-sectional, population-based sample of 856 subjects (mean age 52.82 ± 16.36) classified in three age groups from 15-34 years, 35-54 years and > 54 years of age, living in Khanh Hoa Province, Viet Nam. MS was diagnosed according to the criteria defined by the Third Report of the National Cholesterol Education Program Expect Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel Ⅲ) (NCEP-ATP Ⅲ) and by the modified criteria for some Asian populations in which the waist circumference (WC) is considered abnormal if it is > 90 cm for males and > 80 cm for females.Results Using the NCEP-ATP Ⅲ criteria, the prevalence of MS in the studied population was 10.0% (CI 95 %:8.1-12.3). It was 2.4 % in the 15-34 age group (men 4.5% and women 1.2%),5.2% (men 6.3%,women 4.5% ) in 35-54 age group and 15.8% (men 9.7%, women 21.7%) in over 54 age group, respectively. And it was more common in women than in men (11.7% vs 8.0%, P <0.001). Using 2001 population census data of the whole province over 15 years (695 218 habitants) we estimated that about 35 193 people suffered from the MS.The WC was the least common feature of MS (2.1% for men and in 6.1% for women).Overall,45.2 % of the studied population had one feature of MS, 23.1% had two features, 8.2% had three features, 1.6% had four

    There has been a strong research focus on optical properties in temperate estuaries but very much less in tropical estuaries. These properties comprise light and beam attenuation dominated by suspended particulate matter, Chl a, and CDOM. Spatially and temporally distributed data on optical prope...... estuaries, was the episodic character with days of strong rainfall followed by longer periods of dry weather. All sampling, both wet and dry, was carried out in the dry season which implies a less definitive perception of wet and dry seasons....

    Background A public health intervention program with active involvement of local related stakeholders was piloted in the Bien Hoa dioxin hotspot (2007–2009), and then expanded to the Da Nang dioxin hotspot in Vietnam (2009–2011). It aimed to reduce the risk of dioxin exposure of local residents through foods. This article presents the results of the intervention in Da Nang. Methodology To assess the results of this intervention program, pre- and post-intervention knowledge, attitude, and practice (KAP) surveys were implemented in 400 households, randomly selected from four wards surrounding the Da Nang Airbase in 2009 and 2011, respectively. Results After the intervention, the knowledge on the existence of dioxin in food, dioxin exposure pathways, potential high-risk foods, and preventive measures significantly increased (Pdioxin exposure. Practices to reduce the risk of dioxin exposure also significantly improved (Pdioxin at dioxin hotspots. While greater efforts are needed for remediating dioxin-polluted areas inside airbases, there is also evidence to suggest that, during the past four decades, pollution has expanded to the surrounding areas. For this reason, this model should be quickly expanded to the remaining dioxin hotspots in Vietnam to further reduce the exposure risks in other areas. PMID:23791241

    Little is known about the long-term benefits of interventions that aim to promote early childhood development programs. The goal of this research was to determine whether an early childhood development intervention added to a nutrition intervention during preschool ages had lasting effects on the cognitive development of school-age children in communes of Thanh Hoa province in rural Vietnam. The study focused on a total of 313 children aged 6.5-8.5 y (grades 1 and 2 in primary school) in 2 communes that were exposed to nutrition intervention or nutrition and early childhood development (ECD) intervention from 1999 to 2003. Measurements of height and cognitive test scores (Raven's Progressive Matrices Test) were collected from the children; household characteristics were determined by interviews with mothers. Longitudinal analysis was performed by integrating the data with that collected from the same children in past surveys. Significant effects of the ECD intervention compared with the nutrition intervention were detected. The beneficial effect of ECD intervention on the cognitive test scores was large for the most nutritionally challenged children whose height-for-age Z-scores declined or remained in the stunted range. The findings help provide useful insights into the development of an effective integrated model of ECD and nutrition intervention for children in rural Vietnam.

    The aims of this study were to investigate the prevalence of natural Fasciola infections in both the definitive hosts (cattle) and the intermediate hosts (Lymnaea snails) in central Vietnam. A total of 1,075 fecal samples, randomly collected from cattle in Binh Dinh, Khanh Hoa, and Phu Yen provinces, were examined for Fasciola eggs by a sedimentation method. The overall prevalence of Fasciola was 45.3 %. A subset of the animals (235) was also screened for antibodies against Fasciola by an enzyme-linked immunosorbent assay. Overall, 46.3 % of these animals were shedding Fasciola eggs while 87.2 % were Fasciola seropositive. A lower prevalence of Fasciola was observed in calves ≤ 2 years of age (37.6 %) compared to that in cattle >2 years of age (53.7 %) (p Lymnaea viridis and 1.128 Lymnaea swinhoei examined, 31 (0.95 %) and seven (0.62 %), respectively, were found to be infected with Fasciola. This appears to be the first epidemiological survey of the prevalence of Fasciola in cattle and snails in these three provinces in central Vietnam.

    Full Text Available A cross-sectional study was conducted in Muong Lat town (Thanh Hoa province, North Vietnam, following the confirmed diagnosis of trichinellosis in six patients from that town who had eaten hunted wild boar meat during the Vietnamese lunar year celebration. All inhabitants who declared to have eaten undercooked or raw wild boar meat at the celebration and showed at least one clinical symptom compatible with trichinellosis were included in the study and blood sampled. Anti-Trichinella IgG were determined by ELISA and Western Blot. Seropositive persons were given appropriate albendazole treatment and were followed up. A total of 100 inhabitants met the inclusion criteria. Among these, 30 (30% had antibodies to Trichinella. Serologically confirmed cases had fever (90.0%, myalgia (86.7%, facial oedema (63.3%, diarrhoea (53.3%, and pain of the masseter muscles (43.3%. Eosinophilia was detected in 83.3% of these individuals. Clinical symptoms resolved in all patients during albendazole treatment. The results suggest that only a proportion of the trichinellosis cases had sought health care during the outbreak. There is a need to implement surveillance and better diagnosis for trichinellosis and to set up educational programs to prevent infection in North Vietnam.

    DEFF Research Database (Denmark)

    Barslund, Mikkel Christoffer; Tarp, Finn

    This paper uses a survey of 932 rural households to uncover how the rural credit market operates in four provinces of Vietnam. Households obtain credit through formal and informal lenders, but formal loans are almost entirely for production and asset accumulation. Interest rates fell from 1997...... to 2002, reflecting increased market integration; but the determinants of formal and informal credit demand are distinct. Credit rationing depends on education and credit history, but we find no evidence of a bias against women. Regional differences are striking, and a ‘one size fits all’ approach...

    Pharmacy education programs in Vietnam are complex and offer various career pathways. All include theory and laboratory modules in general, foundation, and pharmaceutical knowledge; placements in health facilities; and a final examination. The various pharmacy degree programs allow specialization in 1 or more of 5 main fields: (1) drug management and supply, (2) drug development and production, (3) pharmacology and clinical pharmacy, (4) traditional medicine and pharmacognosy, and (5) drug quality control, which are offered as main specialization options during the reformed undergraduate and postgraduate programs. However, pharmacy education in Vietnam in general remains product oriented and clinical pharmacy training has not received adequate attention. Only students who have obtained the bachelor of pharmacy degree, which requires a minimum of 5 years of study, are considered as fully qualified pharmacists. In contrast, an elementary diploma in pharmacy awarded after 1 year of pharmacy study permits entry into more junior pharmacy positions. Since the 2000s, there has been a surge in the number and types of schools offering pharmacy qualifications at various levels. PMID:23966717

    The Vietnamese Government's successful development of the National Population and Family Planning Program has contributed in raising people's awareness on population issues and changing their attitudes and behavior regarding fostering small families. It has also been found to be very effective in substantially decreasing fertility level. In addition, economic levels of many households have been greatly improved since the adoption of a renovation policy. The advancement of welfare accompanied by the provision of better basic social services, including health services, has boost people's health. Several factors behind the achievements of the National Population and Family Planning Program include: 1) Strengthening of the political commitment of national and local leaders; 2) Nationwide mobilization of mass organizations and NGOs; 3) A strong advocacy and information, education and communication program; 4) Provision of various kinds of contraceptives; 5) Effective management of the program by priority; and 6) Support of the international community. Despite such successes, Vietnam is facing a number of new issues such as enlargement of the work force, shifting migration patterns and accelerating urbanization, aging of population, and change of household structure. Nevertheless, the Government of Vietnam is preparing a New Population Strategy aimed to address these issues.

    Rapid socioeconomic transformation in Vietnam in last 15 years has been followed by more liberation of sexual expression and representation of sexual identity among young people. There has been an increase in the visibility of homosexual men in major cities of Vietnam who were largely an unknown population until the emergence of the HIV epidemic. Men who have sex with men (MSM) are now considered as one of the target groups in many HIV prevention programs. This qualitative study examines local identities, relationships, and sexual practices among young MSM aged 15-24 in the cities of Hanoi and Ho Chi Minh City. Our analyses were based on 26 in-depth interviews and 10 focus group discussions with young MSM recruited through public place intercepts and cruising areas. Data document the linguistic classification, sexual relationships and behaviors, identity and process of homosexual identification, and the potential linkage between sexual identity and sexual behaviors of MSM in Vietnam. Data also highlight the stages of homosexual community development in urban Vietnam and important differences between Vietnam and the West in the representation of homosexual identity, relationships, and practices. In light of the findings, we suggest that the continuing development and elaboration of a homosexual community in Hanoi and Ho Chi Minh City offers significant opportunities for targeted HIV/AIDS prevention activities in the Vietnamese MSM population.

    2017-04-01

    In the last several years, the interest in forest biomass and carbon stock estimation has increased due to its importance for forest management, modelling carbon cycle, and other ecosystem services. However, no estimates of biomass and carbon stocks of deferent forest cover types exist throughout in the Xuan Lien Nature Reserve, Thanh Hoa, Viet Nam. This study investigates the relationship between above ground carbon stock and different vegetation indices and to identify the most likely vegetation index that best correlate with forest carbon stock. The terrestrial inventory data come from 380 sample plots that were randomly sampled. Individual tree parameters such as DBH and tree height were collected to calculate the above ground volume, biomass and carbon for different forest types. The SPOT6 2013 satellite data was used in the study to obtain five vegetation indices NDVI, RDVI, MSR, RVI, and EVI. The relationships between the forest carbon stock and vegetation indices were investigated using a multiple linear regression analysis. R-square, RMSE values and cross-validation were used to measure the strength and validate the performance of the models. The methodology presented here demonstrates the possibility of estimating forest volume, biomass and carbon stock. It can also be further improved by addressing more spectral bands data and/or elevation.

    This study was undertaken to describe purification, identification, and characteristics of protocatechuic acid (PCA) isolated for the first time from Paenibacillus elgii HOA73 against Botrytis cinerea (the cause of gray mold disease on strawberry fruit). PCA was purified by different chromatographic techniques and identified as PCA (3,4-dihydroxybenzoic acid) by nuclear magnetic resonance and liquid chromatography-mass spectrometry analyses. PCA displayed potent antifungal activity against B. cinerea and Rhizoctonia solani. However, the antifungal activities were not sufficient to inhibit mycelial growth of Phytophthora capsici and Fusarium oxysporum. The minimum inhibitory concentration of PCA to inhibit any visible mycelial growth of both B. cinerea and R. solani was 64 µg ml(-1) . Most B. cinerea conidia displayed altered shape and absence of germination, or were degraded after treatment with 50 and 100 µg ml(-1) PCA, respectively. Moreover, gray mold formation on strawberry fruit was almost or completely inhibited by these PCA concentrations 7 days following infection with B. cinerea conidia, respectively. PCA may be a promising alternative to chemical fungicides as a potential biofungicide to prevent growth of B. cinerea in strawberry fruit disease management.

    2010-10-01

    Full Text Available Exploitation of snakes in Vietnam takes place for different purposes, and among them the snake wine industry is prominent but has received far less attention than other dealings, such as the pet trade. Despite widespread commercialisation there is a general lack of information about this snake trade, which makes it difficult to evaluate its magnitude and impact on snake populations. This study documents the use of snakes in snake wine in four cities in Vietnam through surveys conducted in 127 locations selling snake wine in September 2009. This study provides a list of species used along with the number of individuals observed. While none of the species involved are listed in the IUCN Red List, seven species are listed in the Vietnam Red Data Book, of which five are regulated by CITES. On the other hand, the most abundant species used in the trade, Xenochrophis flavipunctatus, is not listed in any conservation document. The popularity and economic importance of snakes in the form of snake wine demonstrates the need for the development of sustainable use programs for these species.

    It has been well acknowledged that Vietnam is undergoing a nutrition transition. With a rapid change in the country's reform and economic growth, food supply at the macronutrient level has improved. Changes of the Vietnamese diet include significantly more foods of animal origin, and an increase of fat/oils, and ripe fruits. Consequently, nutritional problems in Vietnam now include not only malnutrition but also overweight/obesity, metabolic syndrome and other chronic diseases related to nutrition and lifestyles. The recognition of these shifts, which is also associated with morbidity and mortality, was a major factor in the need to review and update the Recommended Dietary Allowances (RDA) for the Vietnamese population. This revised RDA established an important science-based tool for evaluation of nutrition adequacy, for teaching, and for scientific communications within Vietnam. It is expected that the 2007 Vietnam RDA and its conversion to food-based dietary guidelines will facilitate education to the public, as well as the policy implementation of programs for prevention of non-communicable chronic diseases and addressing the double burden of both under and over nutrition.

    Liver transplantation (LT) has considerably improved the outcome of patients with end-stage liver disease, especially in children. The first pediatric LT in Vietnam was performed in 2004. To assess the current need for pediatric LT in Southern Vietnam, a total of 280 patients with chronic liver disease followed at Children's Hospital 2 (Ho Chi Minh City), the only pediatric LT center in this region, were evaluated from January 2009 to June 2014. Sixty-seven patients satisfied criteria for LT but only one transplant surgery occurred since 2009. Parental consent for LT was obtained only in 28.4% of patients. The main reasons for the small number of LTs were financial costs, far distance from home, lifelong follow-up and treatment, and shortage of organ donors. We conclude that the current need for pediatric LT in Southern Vietnam is high. Efforts should be made to develop the liver transplant program in this developing country.

  20. New strategy toward dioxin risk reduction for local residents surrounding severe dioxin hotspots in Vietnam

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Background: A public health intervention program with active involvement of local related stakeholders was piloted in the Bien Hoa dioxin hotspot (2007–2009, and then expanded to the Da Nang dioxin hotspot in Vietnam (2009–2011. It aimed to reduce the risk of dioxin exposure of local residents through foods. This article presents the results of the intervention in Da Nang. Methodology: To assess the results of this intervention program, pre- and post-intervention knowledge, attitude, and practice (KAP surveys were implemented in 400 households, randomly selected from four wards surrounding the Da Nang Airbase in 2009 and 2011, respectively. Results: After the intervention, the knowledge on the existence of dioxin in food, dioxin exposure pathways, potential high-risk foods, and preventive measures significantly increased (P<0.05. Ninety-eight percent were willing to follow advice on preventing dioxin exposure. Practices to reduce the risk of dioxin exposure also significantly improved (P<0.05. After intervention, 60.4% of households undertook exposure preventive measures, significantly higher than that of the pre-intervention survey (39.6%; χ2=40.15, P<0.001. High-risk foods had quite low rates of daily consumption (from 0 to 2.5% and were significantly reduced (P<0.05. Conclusions: This is seen as an effective intervention strategy toward reducing the risk of human exposure to dioxin at dioxin hotspots. While greater efforts are needed for remediating dioxin-polluted areas inside airbases, there is also evidence to suggest that, during the past four decades, pollution has expanded to the surrounding areas. For this reason, this model should be quickly expanded to the remaining dioxin hotspots in Vietnam to further reduce the exposure risks in other areas.

    Sediment issues have critical implications for aquatic ecology, agriculture, water supply and river navigation. Recently, with the construction and operation of several reservoirs in Da river basin (China-Vietnam), such as Hoa Binh, Lai Chau, Son La and so on, this issue has risen high interest and concern. Reservoirs have been built to meet several important needs, including increasing energy, irrigation, and drinking water demand. However, the decision maker should pay attention to the effects on sediment load, namely trapping of sediments, reduction of sediment concentration downstream reservoirs, increasing riverbank erosion, and localized erosion nearby hydraulic structures. In addition, land use changes, and climate changes are also to be considered as causing effect on sediment erosion and transport. The aim of this work is to evaluate the effects of separate factors (reservoirs, land use change, and climate change) on sediment load in the Da river basin. To this purpose, an updated and enhanced version of the soil erosion and transport model at the catchment scale, namely DIMOSHONG_RUSLE is applied to the Da river basin. More than 50 years of monthly precipitation, runoff and suspended sediment load data are processed. Two historical (1983, 2000) land use maps were generated based on statistic data of the government. The effect of land use change, and reservoirs is assessed on the basis of trends observed in the last decades. To develop the DIMOSHONG_RUSLE model in the period 1961-1985 with land use 1983 (before Hoa Binh reservoir was constructed completely) an updated version of the parameters of the RUSLE equation is determined according to the space variability on the soil types base on experimental data. Then, using chosen optimized parameter of RUSLE, suspended sediment load for the period 1986-2005 (with the Hoa Binh reservoir built and in operation) corresponding with land use in 2000 are calculated. The results are in good agreement with observed

    Background Real-time PCR can be considered the gold standard for detection of influenza viruses due to its high sensitivity and specificity. Roche has developed the RealTime ready Influenza A/H1N1 Detection Set, consisting of a generic influenza virus A PCR targeting the M2 gene (M2 PCR) and a specific PCR targeting the HA of A/H1N1-pdm09 (HA PCR, 2009 H1N1), with the intention to make a reliable, rapid, and simple test to detect and quantify 2009 H1N1 in clinical samples. Methods We evaluated this kit against the USCDC/WHO real-time PCR for influenza virus using 419 nose and throat swabs from 210 patients collected in 3 large hospitals in Ho Chi Minh city, Vietnam. Results In the per patient analysis, when compared to CDC PCR, the sensitivity and specificity of the M2 PCR were 85.8 and 97.6%, respectively; the sensitivity and specificity of HA PCR were 88.2 and 100%, respectively. In the per sample analysis, the sensitivity and specificity in nose swabs were higher than in throat swabs for both M2 and HA PCRs. The viral loads as determined with the M2 and HA PCRs correlated well with the Ct values of the CDC PCR. Conclusion Compared with the CDC PCR, the kit has a reasonable sensitivity and very good specificity for the detection and quantification of Influenza A virus and A/H1N1-pdm09. However, given the current status of 2009 H1N1, a kit that can detect all circulating seasonal influenza viruses would be preferable. PMID:22785431

    The recent decline and death of young cedar, Cedrela odorata L. (Sapindales: Meliaceae), plantations in Vietnam is caused by Aclees sp. (Coleoptera: Curculionidae), a wood-boring brown weevil. A field study was undertaken in three-year-old plantations in two districts in Thanh Hoa province in August 2008. Trees were heavily impacted by the weevil, Aclees; the infestation level (P) ranged from 80 to 100% and the average damage index (R) ranged from 1.8 to 2.8. Observations over one year enabled the life history to be determined. Eggs were laid (February to March, September to November) inside the bark from the base of the trunk up to 60 cm in height. Larvae formed extensive feeding tunnels in the inner bark and sap wood. Pupation occurred in feeding tunnels or pupal chambers in the sapwood. Adults emerged twice a year, February to March and August to October. It is concluded that Aclees is a threat to C. odorata plantations in tropical regions of the world, and quarantine measures should be implemented to reduce the risk of spread.

  5. Spatiotemporal structure of molecular evolution of H5N1 highly pathogenic avian influenza viruses in Vietnam.

    Directory of Open Access Journals (Sweden)

    Margaret A Carrel

    Full Text Available BACKGROUND: Vietnam is one of the countries most affected by outbreaks of H5N1 highly pathogenic avian influenza viruses. First identified in Vietnam in poultry in 2001 and in humans in 2004, the virus has since caused 111 cases and 56 deaths in humans. In 2003/2004 H5N1 outbreaks, nearly the entire poultry population of Vietnam was culled. Our earlier study (Wan et al., 2008, PLoS ONE, 3(10: e3462 demonstrated that there have been at least six independent H5N1 introductions into Vietnam and there were nine newly emerged reassortants from 2001 to 2007 in Vietnam. H5N1 viruses in Vietnam cluster distinctly around Hanoi and Ho Chi Minh City. However, the nature of the relationship between genetic divergence and geographic patterns is still unclear. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we hypothesized that genetic distances between H5N1 viruses in Vietnam are correlated with geographic distances, as the result of distinct population and environment patterns along Vietnam's long north to south longitudinal extent. Based on this hypothesis, we combined spatial statistical methods with genetic analytic techniques and explicitly used geographic space to explore genetic evolution of H5N1 highly pathogenic avian influenza viruses at the sub-national scale in Vietnam. Our dataset consisted of 125 influenza viruses (with whole genome sets isolated in Vietnam from 2003 to 2007. Our results document the significant effect of space and time on genetic evolution and the rise of two regional centers of genetic mixing by 2007. These findings give insight into processes underlying viral evolution and suggest that genetic differentiation is associated with the distance between concentrations of human and poultry populations around Hanoi and Ho Chi Minh City. CONCLUSIONS/SIGNIFICANCE: The results show that genetic evolution of H5N1 viruses in Vietnamese domestic poultry is highly correlated with the location and spread of those viruses in geographic space

    Full Text Available Background In high income countries in Europe and North America, early identification and intervention for autism spectrum disorders (ASD have been linked to improved long-term outcomes. However, in most low and middle income countries (LMIC little is known about the use or availability of such services, which limits the ability of policy and development planning. The purpose of the present study was to assess the use of ASD services in a number of cities in Vietnam, an Asian LMIC, in order to identify areas within the field that should be specifically targeted to improve ASD services in Vietnam. Participants and procedure Surveys were conducted in six different cities across Vietnam with 90 parents/caregivers of children with ASD, 115 professionals working with children with ASD, and 10 directors of agencies providing ASD services. The parents/caregivers’ survey assessed demographics and information regarding their child’s symptoms and services the child received. The professionals’ survey assessed their demographic and professional background, the ASD services they provide, and their perspective on the quality of ASD services at their agency. The directors’ survey included these same questions as well as additional questions regarding the operation of the agency. Results Early identification and intervention ASD services are available in Vietnam, at least in major cities. However, there is a lack of well-trained professionals, the tools used for evaluation and diagnosis are limited, outdated and unstandardized, and the quality of services is questionable. Most importantly, a scientific evidence base for services is absent, and the country lacks an official governmental policy for supporting children with ASD. Conclusions Research directly assessing the quality of ASD services in Vietnam is needed.

The 4 main cities are Ho Chi Minh City with 3.2 million inhabitants,. Hanoi with 1.1 million, Hai Phong with 456,000, and Da Nang with 371,000. Although internal migration has not yet assumed great weight, there has been some rural exodus and movement from poor to richer regions. The policy of population redistribution to reduce density in the Red River delta and central coastal plain and to control city growth has led to some movement. 88% of the population over 10 was literate in 1989. Almost 75% of the population over age 13 is economically active. 71% of the economically active population is employed in agriculture, 12% in industry, and 7% in commerce.

    In many countries worldwide, heavy drinking can cause harm not only to drinkers but also to those around them. To examine the prevalence and predictors of secondhand effects of alcohol use among students in Vietnam. In this cross-sectional study, a multistage sampling strategy was used to select 6,011 students (from the first to final study year) of 12 universities/faculties in four provinces in Vietnam. During class, students filled in a questionnaire asking for demographic information, and about alcohol-related problems and details of secondhand effects of alcohol during the past year. Exploratory factor analysis of the secondhand effects indicated two factors: non-bodily harm and bodily harm. A logistic regression model was used to explore the association between predictors and non-bodily harm and bodily harm. The prevalence of secondhand effects of alcohol is high among students in Vietnam: 77.5% had non-bodily effects and 34.2% had bodily effects. More than 37% of the population reported three to four non-bodily effects and more than 12% reported two to three bodily harms due to the drinking of others. However, most respondents who reported secondhand effects experienced these less than once per month. Factors most strongly associated with the yearly non-bodily harm were the weekly drinking habits of the people the respondents live with, and living in a smaller city; the factor most strongly associated with the yearly bodily harm was the respondent's own alcohol-related problems. Moreover, weekly drinking habits of the people the respondents live with, and respondent's own alcohol-related problems are strongly associated with the frequent experience of non-bodily and bodily effects of alcohol. In addition to dealing with alcohol-related harm of drinkers themselves, preventing secondhand effects should also be a major focus of prevention policy.

    Australian Defence Force (ADF) personnel participated in the Vietnam Conflict from 1962 to 1973, involving nearly 60,000 personnel, of whom over 500 died during service and 3131 were severely physically wounded. Service in the Vietnam conflict presented distinct health challenges. Besides the hazards of combat conditions for extended periods, herbicides and other toxic chemicals were used extensively. The United States military sprayed more than 76,000,000L of herbicide over Vietnam in their Air Force Ranch Hand and Operation Trail Dust programs. The most heavily used herbicide was Agent Orange, contaminated with 2,3,7,8-tetrachlorodibenzo-pdioxin. Since the Vietnam conflict, ex-Service organisations (ESOs) have maintained that Vietnam service adversely affected the health of veterans. Initial studies showed no excess risk attributable to their service. However, more recent studies have shown that Vietnam veterans have excess incidence and mortality rates from several conditions such as cancers and heart disease. This paper describes the first cancer incidence study for all ADF Vietnam veterans.

  1. Understanding Urban Demand for Wild Meat in Vietnam: Implications for Conservation Actions.

    Directory of Open Access Journals (Sweden)

    Rachel Shairp

    Full Text Available Vietnam is a significant consumer of wildlife, particularly wild meat, in urban restaurant settings. To meet this demand, poaching of wildlife is widespread, threatening regional and international biodiversity. Previous interventions to tackle illegal and potentially unsustainable consumption of wild meat in Vietnam have generally focused on limiting supply. While critical, they have been impeded by a lack of resources, the presence of increasingly organised criminal networks and corruption. Attention is, therefore, turning to the consumer, but a paucity of research investigating consumer demand for wild meat will impede the creation of effective consumer-centred interventions. Here we used a mixed-methods research approach comprising a hypothetical choice modelling survey and qualitative interviews to explore the drivers of wild meat consumption and consumer preferences among residents of Ho Chi Minh City, Vietnam. Our findings indicate that demand for wild meat is heterogeneous and highly context specific. Wild-sourced, rare, and expensive wild meat-types are eaten by those situated towards the top of the societal hierarchy to convey wealth and status and are commonly consumed in lucrative business contexts. Cheaper, legal and farmed substitutes for wild-sourced meats are also consumed, but typically in more casual consumption or social drinking settings. We explore the implications of our results for current conservation interventions in Vietnam that attempt to tackle illegal and potentially unsustainable trade in and consumption of wild meat and detail how our research informs future consumer-centric conservation actions.

    2010-07-01

    Full Text Available Intensive shrimp farming is a lucrative and highly risky business. Before entering this industry, most farmers spend time observing the operation of pilot farms. This stage is important to master essential techniques and judge the profitability and risk associated with shrimp farming. Learning is a complex process that leads to misconceptions about the nature of short-term and long-term risks. This paper uses computer simulation to illuminate the dynamic nature of the learning processes, land conversion, shrimp production and environmental contamination. The model is based on conditions of the Dai Hoa Loc Commune in the Mekong Delta of Vietnam. Initial simulations match statistical data by revealing the high risk: high initial profits from the pilot farms followed by conversion from rice land to shrimp farms. When rapid conversion occurs, the region is vulnerable to excessive accumulation of nutrients, a decline in shrimp yields and financial failure. In contrast, low stock densities deliver a lower profit which is insufficient to stimulate mass land conversion. The paper concludes with testing recovery strategies for farmers who have suffered the longer term impacts of high stocking density. Results show that yield recovery is possible by improving the channel and imposing regulatory control over stocking density.

    2009-12-01

    Full Text Available Abstract In the summer of 2009, I visited a humble orphanage for children with HIV/AIDS in Vietnam. Here, like many parts in the world, the very existence of marginalized people with stigmatized illness is hidden away. Relegated to the shadows of society, these children lacked something more fundamental than housing, shelter, nutrition and medications. They lacked families to love and care for them unconditionally. One might think it self-evident that a visit to an orphanage for children with HIV would be profound, but the profundity wasn't where I expected to find it. It was in how the children had created their own family, loving each other like brothers and sisters, and the way the priest who operated the shelters was more than a Father, he was a dad to dozens of children. This is an account of love as harm reduction in the Mai Tam orphanage in Ho Chi Minh City.

    As part of the MILAGRO 2006 field campaign, the exchange of atmospheric aerosols with the urban landscape was measured from a tall tower erected in a heavily populated neighborhood of Mexico City. Urban submicron aerosol fluxes were measured using an eddy covariance method with a quadrupole aerosol mass spectrometer during a two week period in March, 2006. Nitrate and ammonium aerosol concentrations were elevated at this location near the city center compared to measurements at other urban sites. Significant downward fluxes of nitrate aerosol, averaging -0.2 μg m-2 s-1, were measured during daytime. The urban surface was not a significant source of sulfate aerosols. The measurements also showed that primary organic aerosol fluxes, approximated by hydrocarbon-like organic aerosols (HOA), displayed diurnal patterns similar to CO2 fluxes and anthropogenic urban activities. Overall, 47% of submicron organic aerosol emissions were HOA, 35% were oxygenated (OOA) and 18% were associated with biomass burning (BBOA). Organic aerosol fluxes were bi-directional, but on average HOA fluxes were 0.1 μg m-2 s-1, OOA fluxes were -0.03 μg m-2 s-1, and BBOA fluxes were -0.03 μg m-2 s-1. After accounting for size differences (PM1 vs PM2.5) and using an estimate of the black carbon component, comparison of the flux measurements with the 2006 gridded emissions inventory of Mexico City, showed that the daily-averaged total PM emission rates were essentially identical for the emission inventory and the flux measurements. However, the emission inventory included dust and metal particulate contributions, which were not included in the flux measurements. As a result, it appears that the inventory underestimates overall PM emissions for this location.

  12. Potential Economic Impacts of the Vietnam-Korea Free Trade Agreement on Vietnam

    Directory of Open Access Journals (Sweden)

    Thanh Hoan Phan

    2016-03-01

    Full Text Available This paper provides an assessment of the potential economic impacts of the Vietnam-Korea free trade agreement on Vietnam, by using general equilibrium modeling. The results show that Vietnam-Korea FTA will increase aggregate welfare for both countries in the long run. The most important gains accrue from better allocation of resources consequent to trade liberalization. All the sectoral differences and changes are consistent with the trade profiles of the two countries, and the long-run results are more pronounced than those of the short-run. In comparison with other ASEAN countries, the CGE analysis suggests that Vietnam's agriculture exports to Korea would especially rise in the long run. However, there will be strong competition in this sector among ASEAN members. Thus, an earlier conclusion of a comprehensive FTA with Korea is expected to be a good strategy for Vietnam, so as to avoid the direct competition with ASEAN members in the future.

    The thermal power plant is located at Thuy-nguyen District, Haiphong city in Vietnam with an installed capacity of 2×300 MW. Since the power plant is located in a low land near the Gia River with developed karst geo-morphology and thick mucky soil strata on the top, the soil quality is too weak to meet the requirements of the foundation. Bored piles are planned to be used on the main construction area. Pile foundation test is performed in this project area. Mechanism of axial force transfer on the pile and the characteristics of load-settlement of the pile are analyzed. The results suggest that the ultimate bearing capacity of single pile could be 7000kN in this area. The axial force transfer on pile is influenced by many factors. Load on the pile top is transferred down gradually by lateral friction resistance which takes up a great proportion compared with the friction resistance on the pile end. Sediment thickness at the bottom of pile remarkably affects the pile top settlement and the ultimate bearing capacity of pile.%越南海防热电厂二期工程位于海防市(Hai Phong)水源镇(Thuy-nguyen),装机容量为2x300 MW.场地为Gia河边的低地,属于喀斯特地貌区,岩溶比较发育,上部存在较厚的淤泥质土层,土质较差,不能满足厂区上部结构对地基的要求,因此厂区主要建筑物的地基处理采用钻孔灌注桩.对该工程区桩基进行了检测试验,依据桩基试验实测数据,分析了桩身轴力的荷载传递机理以及桩的荷载-沉降特性.结果表明:该工程区的单桩极限承载力可取为7000 kN;桩身轴力的传递特性受多种因素影响,桩顶荷载主要通过桩侧摩阻力逐渐向下传递,具有明显的摩擦桩特点,桩侧摩阻力所占比重较大,而桩端阻力所占比重较小;桩底沉渣厚度显著影响桩顶沉降量与极限承载力.

    From September 2000 to June 2003, a community-based program for dengue control using local predacious copepods of the genus Mesocyclops was conducted in three rural communes in the central Vietnam provinces of Quang Nam, Quang Ngai, and Khanh Hoa. Post-project, three subsequent entomologic surveys were conducted until March 2004. The number of households and residents in the communes were 5,913 and 27,167, respectively, and dengue notification rates for these communes from 1996 were as high as 2,418.5 per 100,000 persons. Following knowledge, attitude, and practice evaluations, surveys of water storage containers indicated that Mesocyclops spp. already occurred in 3-17% and that large tanks up to 2,000 liters, 130-300-liter jars, wells, and some 220-liter metal drums were the most productive habitats for Aedes aegypti. With technical support, the programs were driven by communal management committees, health collaborators, schoolteachers, and pupils. From quantitative estimates of the standing crop of third and fourth instars from 100 households, Ae. aegypti were reduced by approximately 90% by year 1, 92.3-98.6% by year 2, and Ae. aegypti immature forms had been eliminated from two of three communes by June 2003. Similarly, from resting adult collections from 100 households, densities were reduced to 0-1 per commune. By March 2004, two communes with no larvae had small numbers but the third was negative; one adult was collected in each of two communes while one became negative. Absolute estimates of third and fourth instars at the three intervention communes and one left untreated had significant correlations (P = 0.009-dengue disease in the treated communes was reduced by 76.7% compared with non-intervention communes within the same districts, and no dengue was evident in 2002 and 2003, compared with 112.8 and 14.4 cases per 100,000 at district level. Since we had similar success in northern Vietnam from 1998 to 2000, this study demonstrates that this control

    While recent LGBT rights demonstrations and discussions about same-sex marriage have thrust the issue of homosexuality into the spotlight, it was not long ago that the issue of homosexuality was notable by its absence in Vietnam. Drawing on semi-structured interviews with young gay, lesbian and bisexual people in Vietnam's capital city Hanoi, this paper considers the increasing visibility of homosexuality through the theoretical lens of recognition, and illustrates the heterosexist misrecognition that LGBT young people have been subjected to in legislation, the media, their families, and through the education system. Drawing on the narratives of LGBT young people, the paper highlights the potentially negative impact such misrecognition may have on psychological and social wellbeing.

    As a Party to the United Nations Framework Convention on Climate Change (UNFCCC) Viet Nam will make its strong effort to implement the UNFCCC through effective activities in order to reduce GHG emissions as well as enhance carbon sinks in the country. The UNEP/GEF Project `Economics of GHG Limitation - Phase 1: Establishment of a Methodological Framework for Climate Change Mitigation Assessment` developed by the UNEP Collaborating Centre on Energy and Environment (UCCEE) in cooperation with Lawrence Berkeley Laboratory has been deployed in Viet Nam since 1996. The project deals with GHG mitigation analysis and options, focusing on the main issues: a) Associated macro-economics, b) Energy, c) Land use and forestry. For this study, a number of different data related to energy, industry, forestry and agriculture sectors as well as Viet Nam socio-economic development up to the year 2030, are collected. Besides, several models such as MEDEE-S, EFOM-ENV, COMAP are applied for development and assessment of GHG mitigation options in the next decades. The MEDEE-S and EFOM-ENV models are used as a tool for determining the cost-effective strategies to abate GHG emissions for energy sector while COMAP model is applied for forestry sector.

    Full Text Available Purpose: The purpose of the paper is to explore the entry modes of EU firms setting up operations in Vietnam. Design/methodology/approach: we use a case study approach on Haymarket, Cadbury, Creative Education, Fairchild, Aventis and Artemisinin and Farming International using interviews from managerial professionals in Vietnam. Findings: Despite the fact that Vietnam has been opening up for more than 20 years, licensing is the preferred entry mode because of the risks involved in venturing with local firms; that preference signals a low level commitment and a high perception of risk and state interference. In line with Vietnam transition to state - rather than private market - capitalism, a foreign company opting for a joint-venture will do so with a state-owned rather than privately-owned company. The choice of a subsidiary can be explained by the lack of trust in partners and institutions, not by improvement in the socio-political environment. Limitations: In determining the entry mode strategy, the paper focuses on the Uppsala school’s “psychic distance” (e.g. cultural distance, lack of trust rather than on firm-specific advantages (Rugman, 1980; 2006.

    pharmaceutical researchers. A strong decentralisation process characterises the pharmaceutical sector, with pharmacies in the provinces and districts while wholesalers remain located in Hanoi and Saigon. The presence of many middlemen has contributed to an increase in prices. Today, a concentration of pharmacies is still noted in inner cities while the suburbs and the villages still have difficulties supplying drugs for inhabitants. Solutions have been implemented such as the opening of new pharmacies and additional professional training for pharmacists. Prices were lowered while the quality of the supply chain was improved. Local production is encouraged as hospitals are prompted to prescribe Vietnamese products. The modernisation of the Vietnamese pharmaceutical industry is also visible through the importation of medical materials and an increase in the number of private hospitals financed with both the help of local and foreign investors, mainly through joint-ventures, most often in Saigon and Hanoi. The renovation of local hospitals was also possible with the help of France and Japan. Columbia Gia Dinh International, located in Saigon, is one of the very few US/Vietnamese medical institutions created with a local partner, the Gia Dinh hospital. The recovery of the economy will accelerate the creation of new projects designed to improve local medical infrastructures. Other private companies, some of which are based in Singapore, have been specifically designed to deliver care to expatriates working in Vietnam. Insurance coverage has been provided in Vietnam since in 1992. Other improvements concern the implementation of "Good Manufacturing Practices" (GMP) and "Good Laboratory Practices" and "Good Storage Practices". Most norms were implemented at the end of the 90s in joint companies linking foreign investors and local partners or in independent foreign drug manufacturers based in Vietnam. Special areas were created to receive high tech investments in the medical and

    Full Text Available Wind energy has become increasingly important in the total electrical energy supply mix in Vietnam over the last few years. Small, kW turbines were installed in isolated areas a decade ago, while wind farms of several MW to few hundred MW are now being connected directly to national grid, with many additional projects in planning or under construction to fulfill an objective of 6% of the total installed capacity by 2030 (approximately 6200 MW of wind energy component. The increase in wind farm generation results in increased damage from lightning. In this paper, the annual frequency of lightning strikes to wind turbines in Vietnam is calculated using electrogeometric model. Reported lightning incidents to three major wind farms in Vietnam are summarized. Possible causes of failure are discussed, and an EMTP simulation for each incident was performed accordingly. The simulations suggest the failure mechanisms as well the potential of improved grounding to reduce lightning induced damage in future windfarms.

    The South East Asian state of Vietnam is currently undergoing a transition from a centralised socialism to a so-called socialist market economy strongly promoting the private sector. For the last 17 years economy experienced an impressive growth. If the assumption is true that economic growth is positively correlated with the health status of the population, the strengthened economy of Vietnam must go along with an improved health situation and health care system of this country. The following paper evaluates this assumption. It is demonstrated that there is indeed a strongly positive correlation between health and development in many aspects. However, it becomes obvious that economic growth is definitely accompanied by increasing regional and social disparity challenging the health care policy of Vietnam and her international partners.

    Lava flow crises are nothing new on the Island of Hawai‘i, where their destructive force has been demonstrated repeatedly over the past several hundred years. The 2014–2015 Pāhoa lava flow crisis, however, was unique in terms of its societal impact and volcanological characteristics. Despite low effusion rates, a long-lived lava flow whose extent reached 20 km (the longest at Kīlauea Volcano in the past several hundred years) was poised for months to impact thousands of people, although direct impacts were ultimately minor (thus far). Careful observation of the flow reaffirmed and expanded knowledge of the processes associated with pāhoehoe emplacement, including the direct correlation between summit pressurization and flow advance, the influence of existing geologic structures on flow pathways, and the possible relationship between effusion rate and flow length. Communicating uncertainty associated with lava flow hazards was a challenge throughout the crisis, but online distribution of information and direct contact with residents proved to be effective strategies for keeping the public informed and educated about flow progress and how lava flows work (including forecasting limitations). Volcanological and sociological lessons will be important for inevitable future lava flow crises in Hawai‘i and, potentially, elsewhere in the world.

    The objectives of this study were to quantify Salmonella counts on retail raw poultry meat in Vietnam and to phenotypically characterize (serovars and antibiotic resistance) the isolates. A total of 300 chicken carcasses were collected from two cities and two provinces in Vietnam. Salmonella counts on the samples were determined according to the most-probable-number (MPN) method of the U.S. Department of Agriculture, Food Safety and Inspection Service (USDA-FSIS). A total of 457 isolates were serotyped and tested for antibiotic susceptibility. Overall, 48.7% of chicken samples were Salmonella positive with a count of 2.0 log MPN per carcass. There were no significant differences (P > 0.05) in log MPN per carcass by the study variables (market type, storage condition, and chicken production system). There was a significant difference (P salmonellosis). The data revealed that, whereas Salmonella prevalence on raw poultry was high (48.7%), counts were low, which suggests that the exposure risk to Salmonella is low. However, improper storage of raw chicken meat and cross-contamination may increase Salmonella cell counts and pose a greater risk for infection. These data may be helpful in developing risk assessment models and preventing the transmission of foodborne Salmonella from poultry to humans in Vietnam.

    In Da Nang and Ha Long, Vietnam and in Vientiane, Laos, there was interest by local authorities in separating and composting waste in order to reduce environmental and health problems at the local landfills and to produce a soil conditioner for local agricultural use. To assist in the planning of composting projects, three studies were carried out to estimate waste quantities and composition. 1. A 9-day audit of waste from 45 vendors in a market in Vientiane, the capital of Laos. The total quantity of waste and the quantity in each of nine categories were estimated for each of six different types of vendors. 2. A 7-day audit of waste disposed by three hotels in the tourist area of Ha Long, Vietnam. Waste quantities were estimated in total, on a per guest basis, and in three main categories: compostables, recyclables and miscellaneous. 3. A 7-day audit of waste collected from 74 households in Da Nang, the fourth largest city in Vietnam. Waste from each household was separated into compostable and non-compostable waste. Over 60% of each waste source comprised compostable waste and this was considered significant enough to warrant further planning of composting operations.

    A cross-sectional study was conducted on a sample of 291 male motorbike taxi drivers (MMTDs) recruited through social mapping technique in Hanoi, Vietnam, for face-to-face interviews to examine factors associated with drug use among MMTDs using Information-Motivation-Behavioral skills (IMB) model. Among 291 MMTDs, 17.18% reported drug use sometime in their lives, 96% of whom were drug injectors. Being depressed, being originally borne in urban cities, currently residing in rural areas, having a longer time living apart from their wives/lovers, using alcohol, following Buddhism, and reporting lower motivation of HIV prevention predict significantly higher odds of uptaking drugs.

    Large alluvial deltas of the Mekong River in southern Vietnam and Cambodia and the Red River in northern Vietnam have groundwaters that are exploited for drinking water by private tube-wells, which are of increasing demand since the mid-1990s. This paper presents an overview of groundwater arsenic pollution in the Mekong delta: arsenic concentrations ranged from 1-1610 {mu}g/L in Cambodia (average 217 {mu}g/L) and 1-845 {mu}g/L in southern Vietnam (average 39 {mu}g/L), respectively. It also evaluates the situation in Red River delta where groundwater arsenic concentrations vary from 1-3050 {mu}g/L (average 159 {mu}g/L). In addition to rural areas, the drinking water supply of the city of Hanoi has elevated arsenic concentrations. The sediments of 12-40 m deep cores from the Red River delta contain arsenic levels of 2-33 {mu}g/g (average 7 {mu}g/g, dry weight) and show a remarkable correlation with sediment-bound iron. In all three areas, the groundwater arsenic pollution seem to be of natural origin and caused by reductive dissolution of arsenic-bearing iron phases buried in aquifers. The population at risk of chronic arsenic poisoning is estimated to be 10 million in the Red River delta and 0.5-1 million in the Mekong delta. A subset of hair samples collected in Vietnam and Cambodia from residents drinking groundwater with arsenic levels > 50 {mu}g/L have a significantly higher arsenic content than control groups (< 50 {mu}g/L). Few cases of arsenic related health problems are recognized in the study areas compared to Bangladesh and West Bengal. This difference probably relates to arsenic contaminated tube-well water only being used substantially over the past 7 to 10 years in Vietnam and Cambodia. Because symptoms of chronic arsenic poisoning usually take more than 10 years to develop, the number of future arsenic related ailments in Cambodia and Vietnam is likely to increase. Early mitigation measures should be a high priority.

    Full Text Available The purpose of this research is to present and analyse the current situation regarding the capability of the national logistics system in Vietnam. A national assessment framework for macro-logistics is utilised in combination with semi-structured interviews of key Vietnamese stakeholders to reflect on the current situation in the country. There are still numerous shortcomings in the Vietnamese logistics system. These shortcomings are not purely infrastructure based but also from a regulatory and commercial perspective. The presented national logistics system assessment framework can be replicated in other countries or regions when assessing national logistics capability. The findings can help foreign investors, international logistics providers wanting to provide their services in Vietnam to understand the logistics context within the country. These findings are also helpful for policy makers in Vietnam on how to improve their national logistics system. This study proposes a template to assess national logistics systems and provides an in-depth understanding of logistics in Vietnam, a country that has not been much studied in the literature.

    China attracted a record ofUS$52.7×109 in foreign direct investment (FDI) in the year 2002, surpassing the United States to become the world's largest FDI recipient. China's success in attracting FDI has received significant attention from academics. Several theoretical approaches have been developed to explain the determinants of FDI in China.However, it seems to be ignored that China has also become a growing provider of significant FDI to the rest of the world.According to United Nations Conference on Trade and Development (UNCTAD)'s 2004 report, as a developing country,replacing Japan, China has made the list of the expected top five home countries worldwide for the first time in terms of geographical coverage (2004-2005). Vietnam is second largest market and another emerging transition tiger in Southeast Asia. Both China and Vietnam were and are experiencing transitions from centrally planned economy to free market economy. This paper, therefore, attempts to explore the development of Chinese investment in Vietnam, analysing the main motives for, and characteristics of, Chinese Multinational Enterprises' (MNEs) investment in Vietnam.

  3. Abortion in Vietnam: measurements, puzzles, and concerns.

    Science.gov (United States)

    Goodkind, D

    1994-01-01

    This report summarizes current knowledge about abortion in Vietnam, drawing upon government statistics, survey data, and fieldwork undertaken by the author in Vietnam throughout 1993 and part of 1994. The official total abortion rate in Vietnam in 1992 was about 2.5 per woman, the highest in Asia and worrisome for a country with a still-high total fertility rate of 3.7 children per woman. Vietnamese provinces exhibited substantial variation in both the rate of abortion and the type of procedures performed. Among the hypotheses explored to explain Vietnam's high rate of abortion are the borrowing of family planning strategies from other poor socialist states where abortion is common; current antinatal population policies that interact with a lack of contraceptive alternatives; and a rise in pregnancies among young and unmarried women in the wake of recent free-market reforms. Because family-size preferences are still declining, abortion rates may continue to increase unless the incidence of unwanted pregnancy can be reduced, a goal that Vietnamese population specialists are seeking to achieve.

    2016-01-01

    Full Text Available To understand drought adaptation practices, we compared two groups of sugarcane growers in Thanh Cong commune, Thach Thanh district, Thanh Hoa province in Vietnam. Results of this study point out that farmers, depending on their preferred type of market channels, reacted differently to the impacts of drought. Contractual farmers paid more attention to the impact on sugarcane tillering and sugar content, while market-oriented farmers paid more attention to sugarcane colour, as this trait directly determined the market price on the cane that is either consumed as cane or as juice. In responding to water stress in the growing season, the open market-oriented farmers showed more flexibility in changing their cropping calendar. They were also more willing to invest in enhancing the water management system and in providing organic fertilizer than the contractual farmers. On the other hand, the low cane price and the harvesting date set in contract by the processing company lessened the contractual farmers' flexibility in investing in water management technologies; thus, hampering their adaptation to drought.

    1996-01-01

    The lived experience of 24 military nurses during the Vietnam war is described in addition to common elements of their lives after returning from Vietnam. In-depth interviews generated data about personal and professional aspects of the lives of women nurses in the war zone. Data analysis incorporated the qualitative methods of Colaizzi, Lincoln and Guba, and Van Manen. Findings revealed that the nurses struggled with moral and ethical dilemmas of wartime nursing, felt out-of-place, and lacked privacy. The nurses described a deep and special bonding, and many found serving in Vietnam to be the most rewarding experience in their careers. The Vietnam War continues to have an effect on the lives of the nurses who served there. They balance their personal and professional growth gleaned from this experience with the physical and emotional stresses experienced during the war and since the war. The findings of this study have implications for further research about nurses in Vietnam and nurses who have served in other wars.

    2010-09-01

    Full Text Available Abstract Background The rate of H. pylori infection in Vietnam is reportedly high, but the spectrum of H. pylori-associated gastroduodenal diseases has not been systematically investigated. Moreover, despite the similarities of ethnicity and diet, the age-standardized incidence rate of gastric cancer in the northern city of Hanoi is higher than that in the southern city of Ho Chi Minh, but the reason for this phenomenon is unknown. The virulence of Vietnamese H. pylori has also not been investigated in detail. Methods Individuals undergoing esophagogastroduodenoscopy were randomly recruited. H. pylori infection status was determined based on the combined results of culture, histology, immunohistochemistry, rapid urine test and serum ELISA. Peptic ulcer (PU and gastroesophageal reflux disease was diagnosed by endoscopy, and chronic gastritis was determined histologically. H. pylori virulence factors were investigated by PCR and sequencing. Results Among the examined patients, 65.6% were infected with H. pylori. The prevalence of infection was significantly higher in those over 40 years of age than in those aged ≤40. Chronic gastritis was present in all H. pylori-infected individuals, 83.1% of whom had active gastritis, and 85.3% and 14.7% had atrophy and intestinal metaplasia, respectively. PU was present in 21% of infected patients, whereas its incidence was very low in non-infected individuals. The prevalence of PU was significantly higher in Hanoi than in Ho Chi Minh. The prevalence of vacA m1, which has been identified as an independent risk factor for PU in Vietnam, was significantly higher among H. pylori isolates from Hanoi than among those from Ho Chi Minh. Conclusions H. pylori infection is common in Vietnam and is strongly associated with PU, active gastritis, atrophy and intestinal metaplasia. vacA m1 is associated with an increased risk for PU and might contribute to the difference in the prevalence of PU and gastric cancer between

  12. Slaughterhouse pigs are a major reservoir of Streptococcus suis serotype 2 capable of causing human infection in southern Vietnam.

    Directory of Open Access Journals (Sweden)

    Thi Hoa Ngo

    Full Text Available Streptococcus suis is a pathogen of major economic significance to the swine industry and is increasingly recognized as an emerging zoonotic agent in Asia. In Vietnam, S. suis is the leading cause of bacterial meningitis in adult humans. Zoonotic transmission is most frequently associated with serotype 2 strains and occupational exposure to pigs or consumption of infected pork. To gain insight into the role of pigs for human consumption as a reservoir for zoonotic infection in southern Vietnam, we determined the prevalence and diversity of S. suis carriage in healthy slaughterhouse pigs. Nasopharyngeal tonsils were sampled from pigs at slaughterhouses serving six provinces in southern Vietnam and Ho Chi Minh City area from September 2006 to November 2007. Samples were screened by bacterial culture. Isolates of S. suis were serotyped and characterized by multi locus sequence typing (MLST and pulse field gel electrophoresis (PFGE. Antibiotic susceptibility profiles and associated genetic resistance determinants, and the presence of putative virulence factors were determined. 41% (222/542 of pigs carried S. suis of one or multiple serotypes. 8% (45/542 carried S. suis serotype 2 which was the most common serotype found (45/317 strains, 14%. 80% of serotype 2 strains belonged to the MLST clonal complex 1,which was previously associated with meningitis cases in Vietnam and outbreaks of severe disease in China in 1998 and 2005. These strains clustered with representative strains isolated from patients with meningitis in PFGE analysis, and showed similar antimicrobial resistance and virulence factor profiles. Slaughterhouse pigs are a major reservoir of S. suis serotype 2 capable of causing human infection in southern Vietnam. Strict hygiene at processing facilities, and health education programs addressing food safety and proper handling of pork should be encouraged.

    2009-11-01

    During the period of 1965-1968, over two dozen Army microbiologists were deployed to various locations in Southeast Asia in support of the Vietnam War. Their role was to serve both a clinical laboratory mission/function at the mobile Army surgical hospital and mobile laboratory level as well as to perform research roles in all of the facilities. They were essential to the formulation of medical intelligence as well as to the practice of operational medicine in the deployed environment. The results of their laboratory investigations provided commanders and military physicians with critical medical information for patient care, outbreak investigation, and forensic analysis. As with many soldiers in support of the infantry and armor combat forces, most of the work occurs behind the scenes and their contributions are often left out of the historical literature. This article presents a brief overview of microbiology performed by Army microbiologists during the Vietnam War.

  16. Plasmodium knowlesi malaria in Vietnam: some clarifications

    Directory of Open Access Journals (Sweden)

    Hung Le

    2010-01-01

    Full Text Available Abstract A recently published comment on a report of Plasmodium knowlesi infections in Vietnam states that this may not accurately represent the situation in the study area because the PCR primers used may cross-hybridize with Plasmodium vivax. Nevertheless, P. knowlesi infections have been confirmed by sequencing. In addition, a neighbour-joining tree based on the 18S S-Type SSUrRNA gene shows that the Vietnamese samples clearly cluster with the P. knowlesi isolates identified in Malaysia and are distinct from the corresponding P. vivax sequences. All samples came from asymptomatic individuals who did not consult for fever during the months preceding or following the survey, indicating that asymptomatic P. knowlesi infections occur in this population, although this does not exclude the occurrence of symptomatic cases. Large-scale studies to determine the extent and the epidemiology of P. knowlesi malaria in Vietnam are further needed.

  20. A renewal of astronomy education in Vietnam

    Science.gov (United States)

    Wentzel, Donat G.

    Vietnam was scientifically completely isolated for almost 30 years. With French help, several lecture courses have introduced modern astrophysics to Vietnamese physicists, and four students are studying abroad. The IAU program "Teaching for Astronomy Development" (TAD) has concentrated on modernizing the on-going astronomy course for students in the third year of the pedagogical universities. Three one-to-two week "Teachers' Workshops" have served to introduce selected up-to-date astronomical topics and a few modern teaching methods. The TAD program has also provided appropriate journals, books, a PC and educational software. A new text, Astrophysics, in Vietnamese and English on facing pages and with color pictures - apparently a first for any textbook in Vietnam - will first be used starting in September 2000. Future aditional activities: collaboration to plan a new astronomy course in the twelfth grade of the natural science branch of the secondary schools; collaboration so that the 41-cm telescope and astronomers in Hanoi can produce some simple quality science; helping the only planetarium in Vietnam to acquire a wider range of offerings; helping to create a set of B.Sc.-level astrophysics courses for three universities; and supporting the Vietnamese Astronomical Society in effective public outreach.

  1. Impacts of flood on health: epidemiologic evidence from Hanoi, Vietnam

    2011-08-01

    Full Text Available Vietnam is one of the most disaster-prone countries in the world. The country suffers from many kinds of natural disasters, of which the most common and serious one is flooding. Long and heavy rainfall during the last days of October and the first week of November 2008 resulted in a devastating flood unseen for over three decades in the capital city of Hanoi. It caused a substantial health impact on residents in and around the city and compromised the capacity of local health services. The aim of this study is to ascertain the vulnerability and health impacts of the devastating flood in Hanoi by identifying the differences in mortality, injuries, and morbidity patterns (dengue, pink eye, dermatitis, psychological problems, and hypertension between flood affected and non-affected households. A cross-sectional study was carried out involving 871 households in four selected communes (two heavily flood affected and two comparatively less affected from two severely flooded districts of Hanoi. Participants were interviewed and information collected on the social, economic, and health impacts of the devastation within 1 month after the flood. The self-reported number of deaths and injuries reported in this study within 1 month after the heavy rainfall were a bit higher in severely affected communes as compared to that of the less affected communes of our study. The findings showed higher incidences of dengue fever, pink eye, dermatitis, and psychological problems in communes severely affected by flood as compared to that of the controlled communes. For people in flood prone areas (at risk for flooding, flood prevention and mitigation strategies need to be seriously thought through and acted upon, as these people are exposed to greater health problems such as psychological issues and communicable diseases such as pink eye or dermatitis.

  7. Hepatitis C virus in Vietnam: high prevalence of infection in dialysis and multi-transfused patients involving diverse and novel virus variants.

    Directory of Open Access Journals (Sweden)

    Linda Dunford

    Full Text Available Hepatitis C virus (HCV is a genetically diverse pathogen infecting approximately 2-3% of the world's population. Herein, we describe results of a large, multicentre serological and molecular epidemiological study cataloguing the prevalence and genetic diversity of HCV in five regions of Vietnam; Ha Noi, Hai Phong, Da Nang, Khanh Hoa and Can Tho. Individuals (n=8654 with varying risk factors for infection were analysed for the presence of HCV Ab/Ag and, in a subset of positive specimens, for HCV RNA levels (n=475 and genotype (n=282. In lower risk individuals, including voluntary blood donors, military recruits and pregnant women, the prevalence of infection was 0.5% (n=26/5250. Prevalence rates were significantly higher (p<0.001 in intravenous drug users (IDUs; 55.6%, n=556/1000, dialysis patients (26.6%, n=153/575 commercial sex workers (CSWs; 8.7%, n=87/1000, and recipients of multiple blood transfusions (6.0%, n=32/529. The prevalence of HCV in dialysis patients varied but remained high in all regions (11-43% and was associated with the receipt of blood transfusions [OR: 2.08 (1.85-2.34, p=0.001], time from first transfusion [OR: 1.07 (1.01-1.13, p=0.023], duration of dialysis [OR: 1.31 (1.19-1.43, p<0.001] and male gender [OR: 1.60 (1.06-2.41, p=0.026]. Phylogenetic analysis revealed high genetic diversity, particularly amongst dialysis and multi-transfused patients, identifying subtypes 1a (33%, 1b (27%, 2a (0.4%, 3a (0.7%, 3b (1.1%, 6a (18.8%, 6e (6.0%, 6h (4.6%, 6l (6.4% and 2 clusters of novel genotype 6 variants (2.1%. HCV genotype 1 predominated in Vietnam (60%, n=169/282 but the proportion of infections attributable to genotype 1 varied between regions and risk groups and, in the Southern part of Vietnam, genotype 6 viruses dominated in dialysis and multi-transfused patients (73.9%. This study confirms a high prevalence of HCV infection in Vietnamese IDUs and, notably, reveals high levels of HCV infection associated with dialysis and

  8. The impact of social franchising on the use of reproductive health and family planning services at public commune health stations in Vietnam

    2010-02-01

    Full Text Available Abstract Background Service franchising is a business model that involves building a network of outlets (franchisees that are locally owned, but act in coordinated manner with the guidance of a central headquarters (franchisor. The franchisor maintains quality standards, provides managerial training, conducts centralized purchasing and promotes a common brand. Research indicates that franchising private reproductive health and family planning (RHFP services in developing countries improves quality and utilization. However, there is very little evidence that franchising improves RHFP services delivered through community-based public health clinics. This study evaluates behavioral outcomes associated with a new approach - the Government Social Franchise (GSF model - developed to improve RHFP service quality and capacity in Vietnam's commune health stations (CHSs. Methods The project involved networking and branding 36 commune health station (CHS clinics in two central provinces of Da Nang and Khanh Hoa, Vietnam. A quasi-experimental design with 36 control CHSs assessed GSF model effects on client use as measured by: 1 clinic-reported client volume; 2 the proportion of self-reported RHFP service users at participating CHS clinics over the total sample of respondents; and 3 self-reported RHFP service use frequency. Monthly clinic records were analyzed. In addition, household surveys of 1,181 CHS users and potential users were conducted prior to launch and then 6 and 12 months after implementing the GSF network. Regression analyses controlled for baseline differences between intervention and control groups. Results CHS franchise membership was significantly associated with a 40% plus increase in clinic-reported client volumes for both reproductive and general health services. A 45% increase in clinic-reported family planning service clients related to GSF membership was marginally significant (p = 0.05. Self-reported frequency of RHFP service use

    In the past few years, dairy industry has become one of the fastest growing sectors in the packaged food industry of Vietnam. However, the value-added creation among different activities in the value chain of Vietnam dairy sector is distributed unequally. In the production activities, the dairy farmers gain low value-added rate due to high input cost. Whereas the processing activities, which managed by big companies, generates high profitability and Vietnamese consumers seem to have few choices due to the lack of dairy companies in the market. These wicked problems caused an unsustainable development to the dairy value chain of Vietnam. This paper, therefore, will map and analyze the value chain of the dairy industry in Vietnam. It will also assess the value created in each activity in order to imply solutions for a sustainable development of Vietnam's dairy industry. M10, M11.

Urban submicron aerosol fluxes were measured using an eddy covariance method with a quadrupole aerosol mass spectrometer during a two week period in March, 2006. Nitrate and ammonium aerosol concentrations were elevated at this location near the city center compared to measurements at other urban sites. Significant downward fluxes of nitrate aerosol, averaging −0.2 μg m−2 s−1, were measured during daytime. The urban surface was not a significant source of sulfate aerosols. The measurements also showed that primary organic aerosol fluxes, approximated by hydrocarbon-like organic aerosols (HOA, displayed diurnal patterns similar to CO2 fluxes and anthropogenic urban activities. Overall, 47% of submicron organic aerosol emissions were HOA, 35% were oxygenated (OOA and 18% were associated with biomass burning (BBOA. Organic aerosol fluxes were bi-directional, but on average HOA fluxes were 0.1 μg m−2 s−1, OOA fluxes were −0.03 μg m−2 s−1, and BBOA fluxes were −0.03 μg m−2 s−1. After accounting for size differences (PM1 vs PM2.5 and using an estimate of the black carbon component, comparison of the flux measurements with the 2006 gridded emissions inventory of Mexico City, showed that the daily-averaged total PM emission rates were essentially identical for the emission inventory and the flux measurements. However, the emission inventory included dust and metal particulate contributions, which were not included in the flux measurements. As a result, it appears that the inventory underestimates overall PM emissions for this location.

  10. Dengue dynamics in Binh Thuan province, southern Vietnam: periodicity, synchronicity and climate variability.

    Full Text Available BACKGROUND: Dengue is a major global public health problem with increasing incidence and geographic spread. The epidemiology is complex with long inter-epidemic intervals and endemic with seasonal fluctuations. This study was initiated to investigate dengue transmission dynamics in Binh Thuan province, southern Vietnam. METHODOLOGY: Wavelet analyses were performed on time series of monthly notified dengue cases from January 1994 to June 2009 (i to detect and quantify dengue periodicity, (ii to describe synchrony patterns in both time and space, (iii to investigate the spatio-temporal waves and (iv to associate the relationship between dengue incidence and El Niño-Southern Oscillation (ENSO indices in Binh Thuan province, southern Vietnam. PRINCIPAL FINDINGS: We demonstrate a continuous annual mode of oscillation and a multi-annual cycle of around 2-3-years was solely observed from 1996-2001. Synchrony in time and between districts was detected for both the annual and 2-3-year cycle. Phase differences used to describe the spatio-temporal patterns suggested that the seasonal wave of infection was either synchronous among all districts or moving away from Phan Thiet district. The 2-3-year periodic wave was moving towards, rather than away from Phan Thiet district. A strong non-stationary association between ENSO indices and climate variables with dengue incidence in the 2-3-year periodic band was found. CONCLUSIONS: A multi-annual mode of oscillation was observed and these 2-3-year waves of infection probably started outside Binh Thuan province. Associations with climatic variables were observed with dengue incidence. Here, we have provided insight in dengue population transmission dynamics over the past 14.5 years. Further studies on an extensive time series dataset are needed to test the hypothesis that epidemics emanate from larger cities in southern Vietnam.

    Socio-economic development in Vietnam has resulted in increased internal migration particularly among young women seeking employment opportunities in cities. Vietnamese female migrants who enter new environments often encounter the loss or neglect of their right to access sexual and reproductive health services. To address this, a mobile health (mHealth) intervention model was implemented over 12 months (2013-2014) in a factory in the Long Bien industrial zone of Hanoi, Vietnam. The intervention provided sexual and reproductive health services for female migrants through text messaging, information booklets accompanied maps, and free counseling via a hotline. To evaluate the impact of the intervention, pre- and post-intervention data were collected to measure changes in women's knowledge and practices related to sexual and reproductive health. Qualitative data in the form of personal interviews were also collected. The sample size for the baseline survey was 411 women, and for the post-intervention survey it was 482 women (the intervention involved an open cohort). The majority of women were unmarried and under the age of 25. Results indicate that there was high uptake of the intervention services and that most women found the services important and useful. In addition, there was evidence that the intervention (1) increased women's knowledge of sexual and reproductive health (e.g., proper use of condoms, identification of high-risk behaviors such as having unprotected sex), and (2) fostered improved practices related to sexual and reproductive health (e.g., increased gynecological check-ups and use of condoms). The study demonstrated the feasibility of implementing a multi-faceted intervention for migrant women working in an industrial zone in Hanoi, Vietnam as well as its successful uptake and some early positive effects. This can be used to inform future design and implementation of mHealth/eHealth intervention models for migrant and other vulnerable/hard to

    Van Tan Le

    Full Text Available BACKGROUND: Acute encephalitis is an important and severe disease in children in Vietnam. However, little is known about the etiology while such knowledge is essential for optimal prevention and treatment. To identify viral causes of encephalitis, in 2004 we conducted a one-year descriptive study at Children's Hospital Number One, a referral hospital for children in southern Vietnam including Ho Chi Minh City. METHODOLOGY/PRINCIPAL FINDINGS: Children less than 16 years of age presenting with acute encephalitis of presumed viral etiology were enrolled. Diagnostic efforts included viral culture, serology and real time (RT-PCRs. A confirmed or probable viral causative agent was established in 41% of 194 enrolled patients. The most commonly diagnosed causative agent was Japanese encephalitis virus (n = 50, 26%, followed by enteroviruses (n = 18, 9.3%, dengue virus (n = 9, 4.6%, herpes simplex virus (n = 1, cytomegalovirus (n = 1 and influenza A virus (n = 1. Fifty-seven (29% children died acutely. Fatal outcome was independently associated with patient age and Glasgow Coma Scale (GCS on admission. CONCLUSIONS/SIGNIFICANCE: Acute encephalitis in children in southern Vietnam is associated with high mortality. Although the etiology remains unknown in a majority of the patients, the result from the present study may be useful for future design of treatment and prevention strategies of the disease. The recognition of GCS and age as predictive factors may be helpful for clinicians in managing the patient.

  1. Contribution of Water Saving to a Stable Power Supply in Vietnam

    Directory of Open Access Journals (Sweden)

    Takayuki Otani

    2015-06-01

    Full Text Available In Vietnam, the rapid expansion of cities is exceeding the supply capacity for water and electricity, and restrictions on water supply and blackouts occur on a daily basis. In this study, the authors examined whether water-saving equipment could solve these problems. This paper focused on toilet bowls that consumed a large amount of water, and on showers for which heat consumption was high. In Vietnam, the main heat source for showers is the electric water heater, typically having a power consumption of 2500–4500 W. Although the current diffusion rate of such water heaters is just 13%, their use will spread widely in the future. These heaters have already placed a peak load on electricity consumption in winter when a large amount of energy is consumed for heating water, and they will become a significant factor in blackout risks as their use becomes commonplace nationwide. It is clear that the introduction of water-saving showers will allow not only a more efficient use of water resources, but will also mitigate against the risk of blackouts.

    Intellectual disabilities are as prevalent in East Asian countries as in the West (0.06%-1.3%). Widespread discrimination against intellectual disabilities in Asia may initiate stigma that places unfair restrictions on the social life of these individuals and their caregivers. We utilised established stigma frameworks to assess the extent to which a child's intellectual disability contributes to the social exclusion of caregivers in Vietnam. A mixed quantitative and qualitative approach was employed to examine the experience of social life restriction among parents of children with intellectual disabilities. The child's disability level and restrictions on caregivers' social experiences were assessed among 70 mothers and fathers recruited from schools in Hue City, Vietnam. Qualitative responses describing social exclusion were also recorded. Caregivers reported elevated levels of social exclusion. As hypothesised, parents of children with greater intellectual disability experienced more restrictions on their social life (Beta = 0.79, 95% confidence interval 0.27-1.30, standard error = 0.26, p stigma, which in turn restricts key social interactions among caregivers. Psycho-educational interventions may address the social domains in which caregivers are impacted and encourage sustained help-seeking among caregivers for their children.

    A positive association has been reported between elevated tissue organochlorines (p,p'-DDT/p,p'-DDE, PCBs, dioxins) and breast cancer in some case-control studies and occupational cohort studies. We previously reported high serum levels of p,p'-DDT and its metabolite p,p'-DDE in women living throughout Vietnam. We report here the results of a small hospital-based case-control study examining the association between blood levels of p,p'-DDT/p,p'-DDE and the risk of invasive breast cancer among residents of the north of Vietnam-an area where insecticides such as p,p'-DDT have been heavily used in the recent past. The study was conducted among patients admitted to a single hospital in the capital city of Hanoi in 1994. Study subjects were 21 women newly diagnosed with invasive adenocarcinoma of the breast, who served as cases, and 21 women of similar age with fibrocystic breast disease, who served as controls. No increase was evident in the relative risk of breast cancer with increasing tertiles of serum concentration of the compounds of interest, even after adjustment for major potential confounders, such as age at menarche, parity, history of lactation, and body weight. These results suggest that recent and past exposure to p,p'-DDT does not play an important role in the etiology of breast cancer among women living in a country with a tropical climate where insecticide use for mosquito control is common.

    Survey data from men who have sex with men (MSM) in Asian cities indicate ongoing and drastic increases in HIV prevalence. It is unknown which behavioural factors are most important in driving these epidemics. We aimed to analyse detailed sexual behaviour data among MSM in Vietnam and to model HIV transmission using improved assumptions on sexual network structure. Vietnam. Internet-using men who had ever had sex (any type) with a man, aged ≥18 years and living in Vietnam. The study was cross-sectional, population-based and performed in 2012, using online respondent-driven sampling. The Internet-based survey instrument was completed by 982 participants, of which 857 were eligible. Questions included sociodemography and retrospective sexual behaviour, including number of unprotected anal sex (UAS) acts per partner. Estimated basic reproductive number over 3 months as a function of transmission risk per UAS act; frequency distributions of number of UAS partners and UAS acts during last 3 months. 36% (CI 32% to 42%) reported UAS at least once during the last 3 months. 36% (CI 32% to 41%) had ever taken an HIV test and received the result. UAS partner numbers and number of UAS acts were both highly skewed and positively correlated. Using a weighted configuration model, taking into account partner numbers, frequency of UAS and their correlations, we estimated the basic reproductive number (R0) over 3 months. The results indicated rapid transmission over a wide range of values of per-act transmissibility. Men with multiple partners had unexpectedly high UAS frequency per partner, paired with low HIV testing rates. The study highlights the importance of collecting data on frequency of UAS acts and indicates the need to rapidly scale-up HIV prevention services and testing opportunities for MSM in Vietnam.

    2013-09-01

    Government regulation of health professionals is believed to ensure the efficacy and expertise of practitioners for and on behalf of patients. Certification and licensing are two common means to do so, legalizing a physician to practice medicine. However, ethnography from Ho Chi Minh City (HCMC) suggests that in corrupt socioeconomic environments, certification and licensing can alternatively produce a trade in legitimacy. Drawing on participant observations during 15 months of fieldwork with 25 medical acupuncturists in private practice in HCMC, southern Vietnam, and their patients, I argue that everyday practices of corruption and the importance of personal networks meant that legality, efficacy, and expertise separated. Certificates and licenses did not unproblematically validate expertise and efficacy. Consequently, compliance and enforcement of regulations as solutions to inadequate medical care may not achieve the effects intended. © 2013 by the American Anthropological Association.

    Antibiotic residues in aquatic products in Vietnam were investigated. A total of 511 fish and shrimp samples were collected from markets in Ho Chi Minh City (HCMC), Thai Binh (TB), and Nha Trang (NT) from July 2013 to October 2015. The samples were extracted with 2% formic acid in acetonitrile and washed with dispersive C18 sorbent. Thirty-two antibiotics were analyzed by LC-MS/MS. Of the 362 samples from HCMC, antibiotic residues were found in 53 samples. Enrofloxacin was commonly detected, at a rate of 10.8%. In contrast, samples from TB and NT were less contaminated: only 1 of 118 analyzed samples showed residues in TB and only 1 of 31 showed residues in NT. These differences were attributed to the local manufacturing/distribution systems. To understand the current status of antibiotic use and prevent adverse effects that may be caused by their overuse, continual monitoring is required.

    Increases in the rate of HIV infection in Vietnam among female sex workers and their clients require more effective preventive interventions based on a better understanding of this population and important subgroups within it. Because little was known about women in the hospitality sex industry, this study compared demographic and work characteristics, history of sexually transmitted infections (STIs), and condom use among a sample of 310 female sex workers in low-, middle-, and high-class hospitality businesses in Ho Chi Minh City (mean age = 26.77 years, SD = 6.17). Data were collected through individual, face-to-face, semistructured interviews. Logistic regression models were used to identify demographic predictors of the incidence of STIs and reported condom use. Low occupational status was most strongly associated with a history of STIs, and use of condoms with new and regular clients also differed by occupational class. Implications are discussed.

    Full Text Available To identify factors affecting satisfaction with service recovery of banking sector and overall satisfaction, together with the effect of customersatisfaction on repurchase intent and word-of-mouth intent in the banking in Vietnam, a survey is conducted on 215 customers.Those respondents, who are buying services from the bank, namely Vietnamese Local Bank (VLB, have experienced in service failure and service recovery in their transaction with VLB, and lived in Ho Chi Minh City. Structural equation model (SEM is employed to estimate the theoretical model and to test hypotheses. The findings of the study showed that distributive justice positively impact customer satisfaction with service recovery, and overall satisfaction. Satisfaction with recovery has a strong impact on overall satisfaction. Both satisfaction with recovery and overall satisfaction disclose a positive influence on repurchase intent, and only satisfaction with recovery positively affecting word-of-mouth intent.

    2014-05-01

    Mantle xenoliths, spinel lherzolites and subordinate amounts of spinel harzburgites and pyroxenites, are commonly found in alkali basalts from south-central Vietnam. The basalts are part of widespread Neogene volcanism found in southern China and Indochina regions. Samples from different localities between the cities of Ban Me Thuot and Saigon were recovered. In addition one xenolith sample from an off-shore volcano SE of Ho Chi Minh City in the South China Sea was investigated. The mineral assemblage in most samples consists of the simple lherzolitic mineral assemblage Ol-Opx-Cpx-Sp. The Ol, Cpx and Opx crystals are equigranular while Sp occurs usually as smaller sized intersertal phase or as partly oriented inclusions in Cpx. Cpx II occurs in some samples as recrystallized "spongy rim" around Cpx I. Cpx I has a a very uniform composition between different samples with a typical XMg (=Mg/(Mg+Fe2+) of 0.92 to 0.98, a XNa (=Na/(Na+Ca) of 0.10 to 0.16, a Cr2O3 content of 0.6-0.9 wt. .% and Al2O3 values of c. 6 to 8 wt.%. Cpx II has a lower XNa and Al content as well as higher XMg and Cr content compared to Cpx I. Orthopyroxene typically has a XMg of c. 0.90 to 0.93. The XMg values for Ol differ slightly between different samples but are within 0.84 to 0.94. Spinel grains have a variable composition with XMg from 0.65 to 0.92 and XCr (Cr/Cr+Al+Fe3+) of 0.08 to 0.25. The use of the Cpx-Opx thermometer (BREY & KOEHLER, 1990) and the Al and Cr in Ol thermometer (DE HOOG et al., 2010) allowed to constrain the temperature with 800 to 1100 °C. Trace and rare earth element composition of Cpx was determined by LA-ICPMS. While most Cpx compositions are slightly depleted in LREE, typical for average depleted mantle compositions, some samples are strongly enriched in LREE indicating mantle metasomatic processes. The sample displaying the highest level of LREE enrichment in Cpx has the lowest calculated temperature (T = c. 800°C) and the highest Ni content in olivine (3000 ppm

  11. Vietnam and the sustainable development of the Mekong river basis.

    2002-01-01

    Vietnam is a riparian country located in most downstream area of the Mekong river basin which is also shared by other states namely China, Myanmar, Laos, Thailand and Cambodia. While the Central Highlands of Vietnam has a great potential for hydropower development in tributaries of Mekong river, the Mekong delta in Vietnam territory is rich in natural resources which are favorable for agricultural development. However, besides local constraints which being gradually remedied by Vietnam, the development of the Mekong delta is subject to, in both terms of quantity and quality, availability of water resources which relates to the water use of or discharge into the river of upper riparians. With a view to co-developing these resources in a sustainable and mutually beneficial manner, Vietnam has cooperated with other states through framework of the Mekong River Commission set up by the 1995 Mekong Agreement. This paper describes the strategy and action plan applied by Viet Nam National Mekong Committee to reach the sustainable development of the Mekong river basin in general and of Vietnam parts located in the Mekong basin in particular.

    different policy stance than typical in Africa. This is especially so in promoting export-oriented industry. If learning by exporting is a key driver of progress, then a fundamental reason for Africa's lack of transformation is likely to be the low policy priority given to export promotion in the past....... To enlarge the body of empirical evidence, we use an extensive 2005–2012 firm-level panel data set from Vietnam and separate out productivity effects of exporting due to self-selection. This allows us to conclude that firms actually learn by exporting. We also examine how this learning takes place. Our...... findings suggest that productivity gains are associated with moving to larger scale for foreign-owned firms with little evidence of subsequent learning on export markets. We find strong evidence to suggest that private domestic firms learn and accumulate knowledge from export markets with learning...

    1998-10-01

    This is a report on the recent progress in radioisotope production in Vietnam. Using a nuclear research reactor of 500 KW with continuous operation cycles of 100 hours a month, the production of some important radioisotopes used in nuclear medicine and research was routinely carried out. More than 80 per cent of irradiation capacity of reactor for radioisotope production were exploited. The radioactivity of more than 150 Ci of {sup 131}I, {sup 99}Mo-{sup 99m}Tc, {sup 32}P, {sup 51}Cr, {sup 153}Sm, {sup 46}Sc, {sup 192}Ir was produced annually. Radiopharmaceuticals such as {sup 131}I-Hippuran and in-vivo Kits for {sup 99m}Tc labelling were also prepared routinely and regularly. More than 10 in-vivo Kits including modern radiopharmaceuticals such as HmPAO kit were supplied to hospitals in Vietnam. The research on the improvement of dry distillation technology for production of {sup 131}I was carried out. As a result obtained a new distillation apparatus made from glass was successfully put to routine use in place of expensive quartz distillation furnace. We have also continued the research programme on the development of {sup 99m}Tc generators using low power research reactors. Gel technology using Zr- and Ti- molybdate gel columns for {sup 99m}Tc generator production was developed and improved continually. Portable {sup 99m}Tc generator using Zr-({sup 99}Mo) molybdate gel column and ZISORB adsorbent column for {sup 99m}Tc concentration were developed. The ZISORB adsorbent of high adsorption capacity for {sup 99}Mo and other parent radionuclides was also studied for the development purpose of alternative technology of {sup 99m}Tc and other different radionuclide generator systems. The studies on the preparation of therapeutic radiopharmaceuticals labelling with {sup 153}Sm and {sup 131}I such as {sup 153}Sm-EDTMP, {sup 131}I-MIBG were carried out. (author)

    There are persistent differences in self-reported subjective well-being across US metropolitan areas, and residents of declining cities appear less happy than others. Yet some people continue to move to these areas, and newer residents appear to be as unhappy as longer-term residents. While historical data on happiness are limited, the available facts suggest that cities that are now declining were also unhappy in their more prosperous past. These facts support the view that individuals do not maximize happiness alone but include it in the utility function along with other arguments. People may trade off happiness against other competing objectives. PMID:27546979

    This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

  8. Sister Lab Program Prospective Partner Nuclear Profile: Vietnam

    Energy Technology Data Exchange (ETDEWEB)

    2006-12-14

    Vietnam's nuclear program began in the 1960s with the installation at Dalat of a 250 kW TRIGA Mk-II research reactor under the U.S. Atoms for Peace Program. The reactor was shut down and its core removed only a few years later, and the nuclear research program was suspended until after the end of the civil war in the late 1970s. The Soviet Union assisted Vietnam in restoring the Dalat reactor to an operational status in 1984, trained a cadre of scientific and technical staff in its operation, and contributed to the development of nuclear science for the medical and agricultural sectors. In the agricultural area in particular, Vietnamese experts have been very successful in developing mutant strains of rice, and continue to work with the IAEA to yield strains that have a shorter growing period, increased resistance to disease, and other desirable characteristics. Rice has always been the main crop in Vietnam, but technical cooperation with the IAEA and other states has enabled the country to become one of the top rice producers in the world, exporting much of its annual crop to over two dozen countries annually. More recently, Vietnam's government has shown increasing interest in developing a civil nuclear program to supplement its fossil fuel and other energy resources. Projections from a variety of open sources, ranging from the IAEA, the U.S. Department of Energy's Energy Information Administration (EIA), the Vietnamese government, energy corporations, and think tanks all predict a massive increase in energy consumption--especially electricity--within Vietnam and the region as a whole. This growth in consumption will require a corresponding increase in energy production, which in Vietnam is currently satisfied mainly by fossil fuels (coal) and renewable energy (hydropower and biomass); Vietnam has a refining capacity of about 800 barrels/day. Most of its crude oil is exported to generate export income, and is not used to generate electricity

    2011-11-01

    Vietnam has the highest number of primate taxa overall (24-27) and the highest number of globally threatened primate taxa (minimum 20) in Mainland Southeast Asia. Conservation management of these species depends in part on resolving taxonomic uncertainties, which remain numerous among the Asian primates. Recent research on genetic, morphological, and acoustic diversity in Vietnam's primates has clarified some of these uncertainties, although a number of significant classification issues still remain. Herein, we summarize and compare the major current taxonomic classifications of Vietnam's primates, discuss recent advances in the context of these taxonomies, and suggest key areas for additional research to best inform conservation efforts in a region crucial to global primate diversity. Among the most important next steps for the conservation of Vietnam's primates is a new consensus list of Asian primates that resolves current differences between major taxonomies, incorporates recent research advances, and recognizes units of diversity at scales below the species-level, whether termed populations, morphs, or subspecies. Priority should be placed on recognizing distinct populations, regardless of the species concept in use, in order to foster the evolutionary processes necessary for primate populations to cope with inevitable environmental changes. The long-term conservation of Vietnam's primates depends not only on an accepted and accurate taxonomy but also on funding for on-the-ground conservation activities, including training, and the continued dedication and leadership of Vietnamese researchers and managers.

    Full Text Available Abstract Background The aim of this study was to describe and compare breastfeeding practices in rural and urban areas of Vietnam and to study associations with possibly influencing person and household factors. This type of study has not been conducted in Vietnam before. Methods Totally 2,690 children, born from 1st March 2008 to 30th June 2010 in one rural and one urban Health and Demographic Surveillance Site, were followed from birth to the age of 12 months. Information about demography, economy and education for persons and households was obtained from household surveys. Standard statistical methods including survival and regression analyses were used. Results Initiation of breastfeeding during the first hour of life was more frequent in the urban area compared to the rural (boys 40% vs. 35%, girls 49% vs. 40%. High birth weight and living in households with large number of assets significantly increased the probability for early initiation of breastfeeding. Exclusive breastfeeding at three months of age was more commonly reported in the rural than in the urban area (boys 58% vs. 46%, girls 65% vs. 53%. The duration of exclusive breastfeeding as well as of any breastfeeding was longer in the rural area than in the urban area (medians for boys 97 days vs. 81 days, for girls 102 days vs. 91 days. The percentages of children with exclusive breastfeeding lasting at least 6 months, as recommended by WHO, were low in both areas. The duration of exclusive breastfeeding was significantly shorter for mothers with three or more antenatal care visits or Caesarean section in both areas. High education level of mothers was associated with longer duration of exclusive breastfeeding in the rural area. No significant associations were found between duration of exclusive breastfeeding and mother’s age, household economy indicators or household size. Conclusion Intervention programs with the aim to promote breastfeeding are needed. Mothers should

  12. The Dynamics of Urban Agriculture in Hanoi, Vietnam

    2010-06-01

    Full Text Available In many developing countries, urban agriculture makes a significant contribution to the livelihoods of urban populations, in providing food security and income generation. In Hanoi, Vietnam’s capital city, urban agriculture is a longstanding feature, but rapid urban growth is leading to greater competition over land use, such that this practice is being increasingly threatened by conversion to non-agricultural urban uses.  The quality and safety of foodstuffs grown in urban areas is of growing concern to both consumers and producers in developing country cities such as Hanoi, where a large share of the city’s food supply is grown within the urban area. Government support has encouraged urban producers to modernize and invest in safer growing practices. However, in Hanoi, as indeed elsewhere, there is an urgent need to recognise the significance of urban agriculture in future planning strategies. Drawing upon recent field-based research in Hanoi, which examined local actors’ knowledge and perceptions of changes in urban agriculture within the city, the paper identifies key trends and underlying environmental and socio-economic factors, and considers the future sustainability of the practice.Dans de nombreux pays en voie de développement, l’agriculture urbaine représente une contribution significative à la subsistance des populations urbaines, en assurant leur sécurité alimentaire et en générant des revenus. À Hanoi, la capitale du Vietnam, l’agriculture urbaine n'est pas une nouveauté, mais la rapidité de la croissance urbaine intensifie la concurrence pour l'utilisation du sol, et la réaffectation du sol à des fins non agricoles fait peser une menace de plus en plus lourde sur cette pratique. La qualité et la sécurité des produits alimentaires cultivés dans les zones urbaines préoccupent de plus en plus les consommateurs et les producteurs dans les villes des pays en voie de développement telles que Hanoi, où une

    Vietnam has experienced unprecedented economic and social development in recent years, and the livestock sector is undergoing significant transformations. Although food animal production is still dominated by small-scale 'backyard' enterprises with mixed crop-livestock or livestock-aquatic systems, there is a trend towards more intensive and vertically integrated operations. Changes in animal production, processing and distribution networks for meat and animal products, and the shift from wet markets to supermarkets will undoubtedly impact food safety risks in Vietnam in unforeseen and complex ways. Here, we review the available published literature on bacterial and parasitic foodborne zoonoses (FBZ) in Vietnam. We report on clinical disease burden and pathogen prevalence in animal reservoirs for a number of important FBZ, and outline opportunities for future research.

    2007-05-01

    Holocene delta plain development was investigated based on three sediment cores analyzed in detail from the Song Hong (Red River) delta plain in Vietnam. Two cores (DA and PD) from the western delta plain showed both the landward limit of the transgressive estuarine system in the valley incised during the last glacial maximum and floodplain evolution since the middle Holocene. On the other hand, a core (TL) from the eastern delta plain revealed a Pleistocene terrace buried under the deltaic sediments and a slow accumulation rate compared with that in the west. At 8 cal ky BP, the shoreline migrated very close to the present Hanoi city area, and the sedimentary environment changed to tidal flat or salt marsh. Hanoi city marks the northern limit of shoreline transgression. The mangrove swamp expanded from 8 to 5 cal ky BP to the landward limit of the delta plain. Subsequently, the shoreline migrated seaward as a result of delta progradation and sea-level lowering. From 5 cal ky BP, the emerged area evolved into a floodplain and natural levees formed along the abandoned river channels on the western delta plain, but at 2 cal ky, archeological sites indicate that the Holocene terrace in the eastern delta plain was still inundated.

  19. Ensemble climate projections of mean and extreme rainfall over Vietnam

    2017-01-01

    A systematic ensemble high resolution climate modelling study over Vietnam has been performed using the PRECIS model developed by the Hadley Center in UK. A 5 member subset of the 17-member Perturbed Physics Ensembles (PPE) of the Quantifying Uncertainty in Model Predictions (QUMP) project were simulated and analyzed. The PRECIS model simulations were conducted at a horizontal resolution of 25 km for the baseline period 1961-1990 and a future climate period 2061-2090 under scenario A1B. The results of model simulations show that the model was able to reproduce the mean state of climate over Vietnam when compared to observations. The annual cycles and seasonal averages of precipitation over different sub-regions of Vietnam show the ability of the model in also reproducing the observed peak and magnitude of monthly rainfall. The climate extremes of precipitation were also fairly well captured. Projections of future climate show both increases and decreases in the mean climate over different regions of Vietnam. The analyses of future extreme rainfall using the STARDEX precipitation indices show an increase in 90th percentile precipitation (P90p) over the northern provinces (15-25%) and central highland (5-10%) and over southern Vietnam (up to 5%). The total number of wet days (Prcp) indicates a decrease of about 5-10% all over Vietnam. Consequently, an increase in the wet day rainfall intensity (SDII), is likely inferring that the projected rainfall would be much more severe and intense which have the potential to cause flooding in some regions. Risks due to extreme drought also exist in other regions where the number of wet days decreases. In addition, the maximum 5 day consecutive rainfall (R5d) increases by 20-25% over northern Vietnam but decreases in a similar range over the central and southern Vietnam. These results have strong implications for the management water resources, agriculture, bio diversity and economy and serve as some useful findings to be

    2012-08-01

    Full Text Available Abstract Background Diabetes is increasing in prevalence globally, notably amongst populations from low- and middle- income countries. Gestational Diabetes Mellitus(GDM, a precursor for type 2 diabetes, is increasing in line with this trend. Few studies have considered the personal and social effects of GDM on women living in low and middle-income countries. The aim of this study was determine attitudes and health behaviours of pregnant women with GDM in Vietnam. Methods This was a qualitative study using focus group methodology conducted in Ho Chi Minh City. Pregnant women, aged over 18 years, with GDM were eligible to participate. Women were purposely sampled to obtain a range of gestational ages and severity of disease. They were invited to attend a 1-hour focus group. Questions were semi structured around six themes. Focus groups were recorded, transcribed, translated and cross-referenced. Non-verbal and group interactions were recorded. Thematic analysis was performed using a theoretical framework approach. Results From December 2010 to February 2011, four focus groups were conducted involving 34 women. Median age was 31.5 years (range 23 to 44, median BMI 21.8 kg/m2. Women felt confusion, anxiety and guilt about GDM. Many perceived their baby to be at increased risk of death. Advice to reduce dietary starch was confusing. Women reported being ‘hungry’ or ‘starving’ most of the time, unaware of appropriate food substitutions. They were concerned about transmission of GDM through breast milk. Several women planned not to breastfeed. All felt they needed more information. Current sources of information included friends, magazines, a health phone line or the Internet. Women felt small group sessions and information leaflets could benefit them. Conclusions This study highlights the need for culturally appropriate clinical education and health promotion activities for women with GDM in Vietnam.

  6. 'Hu Hong' (bad thing): parental perceptions of teenagers' sexuality in urban Vietnam.

    Teenagers under 18 years old in Vietnam are considered as minors who usually lack the autonomy to make decisions. They are also sometimes viewed as contributors to social evils including crime, violence and substance use. Moreover, most Vietnamese teenagers have unsafe sex before marriage. The objective of this study is to explore the parental perceptions relating to their teenagers' sexuality, particularly the social and cultural forces, that may hinder access to sexuality information. Guided by a Community Advisory Board (CAB), this qualitative study uses four focus group discussions (FGDs) consisting of 12 mothers and 12 fathers, as well as twelve individual in-depth interviews (IDIs) with a diverse sample of parents of teens in Ho Chi Minh City (HCMC), Vietnam. Content and discourse analysis were conducted, based on Foucauldian concepts. Four themes emerged: 1) Meanings of sexuality and sexuality education, 2) Early sexual intercourse destroys teenagers' future, 3) Teenagers are not hu hong (spoil/bad thing), are innocent and virgin, and 4) Policing and controlling of sexual intercourse among teens. Parents did not view their teenage children as sexual beings; those who are sexual are considered hu hong. Parents believed that teens need to be policed and controlled to prevent them from becoming hu hong, particularly girls. Controlling of sexuality information by parents was therefore common in HCMC, but differed by gender and educational levels of parents. For example, fathers more than mothers were not comfortable teaching their teenage children about sex and sexuality. Parents with higher education police their teenage children's usage of the Internet and social media, while parents with lower education control who can be friends with their teenage children. Vietnamese parents in general have negative views of sex and sexuality education for their teenage children. Recognizing that many Vietnamese teenagers have unsafe sex before marriage, parents need to

    Motorcyclist injuries and fatalities are a major concern of many developing countries. In Vietnam, motorcycles are involved in more than 70% of all road traffic crashes. This paper aims to explore the prevalence and factors associated with mobile phone use among motorcyclists and electric bike riders, using a case study of Hanoi, Vietnam. A cross-sectional observation survey was undertaken at 12 sites, in which each site was surveyed during a two-hour peak period from 16:30 to 18:30 for two weekdays and one weekend day. A total of 26,360 riders were observed, consisting of 24,759 motorcyclists and 1601 electric bike riders. The overall prevalence of mobile phone use while riding was 8.4% (95% CI: 8.06-8.74%) with calling having higher prevalence than screen operation: 4.64% (95% CI: 4.39-4.90%) vs. 3.76% (95% CI: 3.52-3.99%) respectively. Moreover, the prevalence of mobile phone use was higher among motorcyclists than electric bike riders: 8.66% (95%CI: 8.30-9.01%) vs. 4.43% (95% CI: 3.40-5.47%) respectively. Logistic regression analyses revealed that mobile phone use while riding was associated with vehicle type, age, gender, riding alone, weather, day of week, proximity to city centre, number of lanes, separate car lanes, red traffic light duration, and police presence. Combining greater enforcement of existing legislations with extensive education and publicity programs is recommended to reduce potential deaths and injuries related to the use of mobile phones while riding.

  8. EVALUATION OF THE TRADE RELATIONSHIP BETWEEN VIETNAM AND CHINA; VIETNAM AND UNITED STATES: A COMPARISON USING GRAVITY MODEL

    2017-06-01

    Full Text Available This study aims to evaluate the determinants of trade relationship between two largest trading partners of Vietnam, United States and China. Using gravity model for time series data from 1986 to 2015, the study found that economic growth rate plays a crucial role in stimulating the trade flow. Both trade relationships fit with the practical approach of Heckscher-Ohlin theory, stating that trade flow increases between countries with different income levels. The most important finding of this study lines on the results regarding the impact of trade agreements. While United States-Vietnam bilateral agreement creates trade, the trade agreement between ASEAN and China produced trade diversion. As China expands its markets among ASEAN countries, Vietnam should diversify its export markets to improve its export flow.

    Full Text Available Abstract Background Despite the increasing prevalence of type 2 diabetes in urban areas, relatively little has been known about its actual prevalence and its associations in rural areas, Vietnam. The purpose of this study was to evaluate the prevalence of impaired fasting glucose (IFG, impaired glucose tolerance (IGT, diabetes and their risk factors in a rural province, Vietnam. Methods A cross–sectional study with a representative sample was designed to estimate the hyperglycemia prevalence, using 75–g oral glucose tolerance test. Potential risk factors for hyperglycemia were analyzed using multinomial logistic regression, taken into account influences of socio–economic status, anthropometric measures, and lifestyle–related factors. Results The age and sex–adjusted prevalence rates (95% CI of isolated IFG, isolated IGT, combined IFG–IGT, and diabetes were 8.7 (7.0–10.5, 4.3 (3.2−5.4, 1.6 (0.9−2.3, and 3.7% (2.7–4.7%, respectively. There were still 73% of diabetic subjects without knowing the condition. Blood pressure, family history of diabetes, obesity–related measures (waist circumference, waist–hip ratio, body fat percentage, and abdominal obesity were the independent risk factors for hyperglycemia (IFG, IGT, and diabetes. Conclusions The prevalence of hyperglycemia in rural areas has not been as sharply increased as that reported in urban cities, Vietnam. Blood pressure and obesity–related measures were the most significant predictors for hyperglycemia level and they can be taken into account in building prognosis models to early detection of diabetes in rural Vietnamese populations.

    2014-09-01

    Euscorpiops dakrong sp. n., belonging to the family Euscorpiidae Laurie, is described on the basis of one male and one female collected in the Dakrong Nature Reserve cave system, Dakrong District, Quang Tri Province, Vietnam. The new species presents most features exhibited by scorpions of the genus Euscorpiops, but it is characterized by a slender body and elongated pedipalps. This new scorpion taxon represents the second species of Scorpiopinae discovered in a cave system and may be yet another endemic element in the fauna of Vietnam. Some taxonomic propositions on the generic position of Scorpiops oligotrichus Fage, 1933 are also suggested.

    This analysis used data, primarily from the 1997 Vietnamese Demographic and Health Survey (VN-DHS 1997), to determine the changes in contraceptive use in Vietnam. A descriptive analysis of individual, household and community characteristics was made to obtain a general description of contraceptive use. Multinomial logistic regression analyses were also performed on the currently married in (a) a sample of all women and (b) only those women who live in rural areas, to identify the strength of association that each variable has with the use of modern contraceptives. The use of any contraceptive method and the use of modern methods increased from 1988 to 1997. The primary contraceptive method utilized is the IUD and its use has increased substantially from 1988 to 1997. Younger women (aged 15-24) were less likely to use any contraceptive method. Women not desiring additional children were significantly more likely to use contraceptive methods than those desiring more children. Education has a clear impact on both contraceptive knowledge and use by women, with higher educated women being more likely to use a contraceptive method. Illiterate women with no formal education were significantly less likely to use modern methods of contraception. Differentials in contraceptive use exist regarding place of residence. Urban women are more likely than rural women to use contraception, but the difference is not large. Women living in mountainous areas are less likely to use contraception, compared with women living in the lowlands. Living standards, especially the availability of electricity in the community, have a large effect on the methods of contraception adopted by women. Religion is not strongly related to the contraceptive behaviour of women. There were significant differences in the use of contraceptives in communities with good quality of care, with increased contraceptive use corresponding to the increase in availability of family planning workers at communes

    2016-01-01

    Supported by GAVI Alliance, measles-rubella vaccination was introduced in Vietnam in 2014, involving a mass campaign among 1-14 year olds and routine immunization of children aged 9 months. We explore the impact on the incidence of Congenital Rubella Syndrome (CRS) during 2013-2050 of this strategy and variants involving women aged 15-35 years. We use an age and sex-structured dynamic transmission model, set up using recently-collected seroprevalence data from Central Vietnam, and also consider different levels of transmission and contact patterns. If the serological profile resembles that in Central Vietnam, the planned vaccination strategy could potentially prevent 125,000 CRS cases by 2050 in Vietnam, despite outbreaks predicted in the meantime. Targeting the initial campaign at 15-35 year old women with or without children aged 9 months-14 years led to sustained reductions in incidence, unless levels of ongoing transmission were medium-high before vaccination started. Assumptions about contact greatly influenced predictions if the initial campaign just targeted 15-35 year old women and/or levels of ongoing transmission were medium-high. Given increased interest in rubella vaccination, resulting from GAVI Alliance funding, the findings are relevant for many countries.

  3. Current status of fasciolosis in Vietnam: an update and perspectives.

    2016-09-01

    Vietnam is recognized to be endemic for fasciolosis. However, most of the available publications have not been published in international journals. This review is based on national and international Vietnamese publications and highlights the current status of fasciolosis in Vietnam. It also provides some information available for neighbouring countries. Updated data on responsible species, distribution, transmission and control aspects are summarized. The central region of Vietnam is reported as being highly endemic for fasciolosis, with a high number of human patients (more than 20,000 in 2011). Fasciola gigantica is reported to be the main species in Vietnam. However, hybrids between F. gigantica and F. hepatica were identified. Both humans and animals are infected by the ingestion of raw vegetables and possibly contaminated drinking water. Three lymnaeid snail species (Austropeplea viridis, Radix auricularia and Radix rubiginosa) may act as intermediate hosts of Fasciola spp. However, due to the likely misidentification of snail species and cercariae during the past decade the critical analysis of published data is difficult. A better understanding of transmission aspects of fasciolosis would allow the implementation of preventive measures of this important neglected zoonotic disease.

    There is limited understanding of Autism spectrum disorder (ASD) in Vietnam. This ethnographic study aimed to explore how ASD is represented and managed in the cultural, social and economic contexts of Vietnam, and describe the experiences of families with children with ASD in Hanoi, Vietnam. This study was conducted from 2011 to 2012 in Hanoi and employed a range of methods, including participant observation, in-depth interviews with 27 parents of children with ASD and 17 key informants, and online survey. This study found that within Hanoi, Vietnam, ASD has been culturally and socially constructed as a 'disease', 'karmic demerit' and 'family problem' rather than a life-long developmental disorder that needs support from government. Children with ASD and their families experience various forms of stigma and discrimination. There are limitations in assessment and diagnosis of ASD. Parents of children with ASD have little access to services for their children, and the limited political and economic supports exacerbate their difficulties. This study highlights some of the ways in which the understandings and management of ASD vary cross culturally. It also suggests further attention is required to the provision of appropriate public education, low cost interventions and support for family advocacy groups.

  6. Current status of taeniasis and cysticercosis in Vietnam.

    2014-04-01

    Several reports on taeniasis and cysticercosis in Vietnam show that they are distributed in over 50 of 63 provinces. In some endemic areas, the prevalence of taeniasis was 0.2-12.0% and that of cysticercosis was 1.0-7.2%. The major symptoms of taeniasis included fidgeted anus, proglottids moving out of the anus, and proglottids in the feces. Clinical manifestations of cysticercosis in humans included subcutaneous nodules, epileptic seizures, severe headach, impaired vision, and memory loss. The species identification of Taenia in Vietnam included Taenia asiatica, Taenia saginata, and Taenia solium based on combined morphology and molecular methods. Only T. solium caused cysticercosis in humans. Praziquantel was chosen for treatment of taeniasis and albendazole for treatment of cysticercosis. The infection rate of cysticercus cellulosae in pigs was 0.04% at Hanoi slaughterhouses, 0.03-0.31% at provincial slaughterhouses in the north, and 0.9% in provincial slaughterhouses in the southern region of Vietnam. The infection rate of cysticercus bovis in cattle was 0.03-2.17% at Hanoi slaughterhouses. Risk factors investigated with regard to transmission of Taenia suggested that consumption of raw meat (eating raw meat 4.5-74.3%), inadequate or absent meat inspection and control, poor sanitation in some endemic areas, and use of untreated human waste as a fertilizer for crops may play important roles in Vietnam, although this remains to be validated.

    2014-09-15

    Building on new institutional theory, this paper develops an analytical framework for analyzing constraints to the institutionalization of strategic environmental assessment (SEA) at four different institutional levels. The framework is tested in an empirical analysis of the environmental assessment system in Vietnam, which is a frontrunner among developing countries regarding the introduction and use of SEA. Building on interviews with Vietnamese and international experts, as well as an extensive literature review, we identify institutional constraints which challenge the effective use of SEA in Vietnam. We conclude that commonly identified constraints, such as inadequate training, technical guidelines, baseline data and financial resources, are strongly linked to constraints at higher institutional levels, such as incentives to not share information between ministries and severe restrictions on access to information and public participation. Without a thorough understanding of these institutional constraints, there is a risk that attempts to improve the use of SEA are misdirected. Thus, a careful institutional analysis should guide efforts to introduce and improve the use of SEA in Vietnam and other developing countries. The analytical framework for analyzing constraints to institutionalization of SEA presented in this paper represents a systematic effort in this direction. - Highlights: • A framework for analyzing constraints to institutionalizing SEA is developed • Empirical analysis of the strategic environmental assessment system in Vietnam • Constraints in the action arena linked to deeper institutional constraints • Institutional analysis needed prior to introducing SEA in developing countries.

  20. HCV 6a prevalence in Guangdong province had the origin from Vietnam and recent dissemination to other regions of China: phylogeographic analyses.

    Directory of Open Access Journals (Sweden)

    Yongshui Fu

    Full Text Available BACKGROUND: Recently in China, HCV 6a infection has shown a fast increase among patients and blood donors, possibly due to IDU linked transmission. METHODOLOGY/FINDINGS: We recruited 210 drug users in Shanwei city, Guangdong province. Among them, HCV RNA was detected in 150 (71.4%, both E1 and NS5B genes were sequenced in 136, and 6a genotyped in 70. Of the 6a sequences, most were grouped into three clusters while 23% represent emerging strains. For coalescent analysis, additional 6a sequences were determined among 21 blood donors from Vietnam, 22 donors from 12 provinces of China, and 36 IDUs from Liuzhou City in Guangxi Province. Phylogeographic analyses indicated that Vietnam could be the origin of 6a in China. The Guangxi Province, which borders Vietnam, could be the first region to accept 6a for circulation. Migration from Yunnan, which also borders Vietnam, might be equally important, but it was only detected among IDUs in limited regions. From Guangxi, 6a could have further spread to Guangdong, Yunnan, Hainan, and Hubei provinces. However, evidence showed that only in Guangdong has 6a become a local epidemic, making Guangdong the second source region to disseminate 6a to the other 12 provinces. With a rate of 2.737×10⁻³ (95% CI: 1.792×10⁻³ to 3.745×10⁻³, a Bayesian Skyline Plot was portrayed. It revealed an exponential 6a growth during 1994-1998, while before and after 1994-1998 slow 6a growths were maintained. Concurrently, 1994-1998 corresponded to a period when contaminated blood transfusion was common, which caused many people being infected with HIV and HCV, until the Chinese government outlawed the use of paid blood donations in 1998. CONCLUSIONS/SIGNIFICANCE: With an origin from Vietnam, 6a has become a local epidemic in Guangdong Province, where an increasing prevalence has subsequently led to 6a spread to many other regions of China.

Although the HIV epidemic among this population in Vietnam is increasingly acknowledged, understanding the impact of drug use on the spread of HIV is largely lacking. Using qualitative data from in-depth interviews and focus group discussions with 93 drug users, 15 non-drug users and 9 community stakeholders, this analysis explores emerging patterns of drug use and risk factors for engaging in risk behaviours among drug-using men having sex with men, men selling sex and transgender individuals in Hanoi and Ho Chi Minh City. Findings revealed that drug use is shifting from heroin to ecstasy and ice. Drug users reported unsafe sex associated with drug use and men selling sex were particularly at elevated risk because of using drugs as a tool for sex work and trading sex for drugs. These findings are guiding development of programmes addressing unmet HIV-prevention needs in Vietnam.

    Research on extramarital sex (EMS) is commonly conducted from a perspective that implicitly understands this behavior as a violation of the marital relationship. In contrast, Vietnamese cultural norms have, at some points in history, condoned if not outright encouraged EMS in the name of preserving family lineage. Yet little is known about the prevalence of EMS among contemporary Vietnamese men and its association with marriage quality. This is a notable gap, given the enormous sociocultural and ideological shifts the country has experienced over the past several decades. Drawing upon a sample of 126 married men (Mean age = 45.56; SD = 10.52) surveyed in urban (Hanoi and Ho Chi Minh City) and rural areas (Ha Tay and Can Tho) in Vietnam, we examined the relationship between EMS and geographic region, demographic characteristics, sexual values, quality of marriage, and sexual satisfaction within marriage. Our results show that geographic location had a strong impact on EMS, while most marital relationship quality variables did not impact the odds of EMS for married men in Vietnam.

  4. Branding Cities, Changing Societies

    DEFF Research Database (Denmark)

    Ooi, Can-Seng

    Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

    Full Text Available Abstract Background The Mental Health Country Profile is a tool that was generated by the International Mental Health Policy and Services Project to inform policy makers, professionals and other key stakeholders about important issues which need to be considered in mental health policy development. The Mental Health Country Profile contains four domains, which include the mental health context, resources, provision and outcomes. We have aimed to generate a Mental Health Country Profile for Vietnam, in order to highlight the strengths and weaknesses of the Vietnamese mental health situation, in order to inform future reform efforts and decision-making. Methods This study used snowball sampling to identify informants for generating a Mental Health Country Profile for Vietnam, and the data gathering was done through semi-structured interviews and collection of relevant reports and documents. The material from the interviews and documents was analysed according to qualitative content analysis. Results Marked strengths of the Vietnam mental health system are the aims to move toward community management and detection of mental illness, and the active involvement of several multilateral organizations and NGOs. However, there are a number of shortages still found, including the lack of treatment interventions apart from medications, the high proportion of treatments to be paid out-of-pocket, prominence of large tertiary psychiatric hospitals, and a lack of preventative measures or mental health information to the public. Conclusions At the end of this decade, mental health care in Vietnam is still characterised by unclear policy and poor critical mass especially within the governmental sector. This initial attempt to map the mental health situation of Vietnam suffers from a number of limitations and should be seen as a first step towards a comprehensive profile.

Methods: The study subjects were women (n = 258 undergoing early MA through 12 private providers in Hanoi during February-June 2012. The women were interviewed on the day of their procedure and were followed up by telephone 14 days after mifepristone administration. Results: Of the 258 women in the study, 97% used a regimen of mifepristone plus misoprostol; 80% were instructed to administer misoprostol at home. MA resulted in a complete termination in 90.8% of cases. All women were provided with information on potential complications and were instructed to return for a follow-up visit. We successfully followed up 77.5% (n = 200 of participants by telephone, while nearly two-thirds of women returned to the clinic for a follow-up visit. At follow up, 39.5% of women reported having used a Help line service, while 7% had sought help from a health provider. A high unmet need for postabortion family planning was identified. Conclusion: Follow up of women, postabortion care, and the provision of family planning have been identified as important areas to address for strengthening MA services in the private sector in Vietnam. Keywords: misoprostol, mifepristone, abortion, mhealth, Vietnam

    Cashew (Anacardium occidentale L.) is a very important source of income for more than 200,000 farmer households in Vietnam. The present cashew productivity in Vietnam is low and unstable, and pest damage is partly responsible for this. Cashew farmers rely on pesticides to minimize the damage, resulting in adverse impacts on farm environment and farmers' health. Weaver ants (Oecophylla spp) are effective biocontrol agents of a range of cashew insect pests in several cashew-growing countries, and these ants are widely distributed in Vietnam. The aim of this study is to evaluate the potential of weaver ants in cashew orchards in Vietnam. Field surveys and field experiment were conducted in five cashew orchards from July 2006 to January 2008 in Binh Phuoc, Dong Nai, and Ba Ria Vung Tau provinces, Vietnam. Based on the field surveys, the most important pests that damage flushing foliar and floral shoots and young cashew fruits and nuts were mosquito bugs, brown shoot borers, blue shoot borers, and fruit-nut borers. The damage caused by each of these pests was significantly lower on trees with weaver ants compared with trees without the ants, showing that the ants were able to keep these pest damages under the control threshold. Regular monitoring of the field experiment showed that weaver ants were similar to insecticides for controlling mosquito bugs, blue shoot borers, fruit-nut borers, leaf rollers, and leaf miners. Aphids did not become major pests in plot with weaver ants. To manage insect pest assemblage in cashew orchards, an integrated pest management using weaver ants as a major component is discussed.

    The study domain covered the Eastern region of Southern of Vietnam that includes Ho Chi Minh City (HCMC) and five other provinces. Rice production in the domain accounted for 13% of the national total with three crop cycles per year. We assessed ozone (O{sub 3}) induced rice production loss in the domain for 2010 using simulated hourly surface O{sub 3} concentrations (WRF/CAMx; 4 km resolution). Simulated O{sub 3} was higher in January–February (largely overlaps the first crop) and September–December (third crop), and lower in March–June (second crop). Spatially, O{sub 3} was higher in downwind locations of HCMC and were comparable with observed data. Relative yield loss (RYL) was assessed for each crop over the respective growing period (105 days) using three metrics: AOT40, M7 and flux-based O{sub 3} dose of POD{sub 10}. Higher RYL was estimated for the downwind of HCMC. Overall, the rice production loss due to O{sub 3} exposure in the study domain in 2010 was the highest for the first crop (up to 25,800 metric tons), the second highest for the third crop (up to 21,500 tons) and the least for the second crop (up to 6800 tons). The low RYL obtained for the second crop by POD{sub 10} may be due to the use of a high threshold value (Y = 10 nmol m{sup −2} s{sup −1}). Linear regression between non-null radiation POD{sub 0} and POD{sub 10} had similar slopes for the first and third crop when POD{sub 0} was higher and very low slope for the second crop when POD{sub 0} was low. The results of this study can be used for the rice crop planning to avoid the period of potential high RYL due to O{sub 3} exposure. - Highlights: • Simulated O{sub 3} was used to assess rice yield loss in a domain of Southern Vietnam. • Exposure metrics of AOT40, M7, POD{sub 0} and POD{sub 10} were considered. • POD{sub 10} gave the highest rice production loss. • Higher production loss was found downwind of Ho Chi Minh City.

    Full Text Available Background: Health risk behavior among young people is a public health problem in Vietnam. In addition, road traffic injuries are the leading cause of death for those aged 15–29 years. The consequences can be devastating for adolescents and their families, and can create a significant economic burden on society. Objective: The aim of this study was to identify protective and risk factors that may influence three health risk behaviors among school children: suicidal thinking (ST, drinking alcohol (DA, and underage motorbike driving (MD. Methods: A cross-sectional survey of 972 adolescents (aged 12–15 years was conducted in two secondary schools in Hanoi, Vietnam. The schools were purposely selected, one each from the inner city and a suburban area, from which classes (grade 6 to 8 were randomly selected. All students attending classes on survey days took part in the survey. The anonymous, self-completed questionnaire included measures of risk behavior, school connectedness, parental bonding, and other factors. Multivariable regression models were used to examine associations between the independent variables and the three health risk behaviors controlling for confounding factors. Results: Young people in the inner city school reported a higher prevalence of all three risk behaviors than those in the suburban area (ST: 16.1% [95% confidence interval, or CI, 12.9–19.3] versus 4.6% [95% CI 2.7–6.5], p<0.001; DA: 20.3% [95% CI 16.8–23.8] versus 8.3% [95% CI 5.8–10.8], p<0.001, and MD: 10.1% [95% CI 7.4–12.8] versus 5.7% [95% CI 3.6–7.8], p<0.01. School connectedness and mother and father care appeared to be significant protective factors. For males, bullying in school was associated with suicidal thoughts, whereas for both males and females, school connectedness may be protective against suicidal ideation. Conclusion: This study supports findings from other nations regarding suicidal thoughts and alcohol use, and appears to be one of

    Vietnam has pursued universal health insurance coverage for two decades but has yet to fully achieve this goal. This paper investigates the barriers to achieve universal coverage and examines the validity of facilitating factors to shorten the transitional period in Vietnam. A comparative study of facilitating factors toward universal coverage of Vietnam and Korea reveals significant internal forces for Vietnam to further develop the National Health Insurance Program. Korea in 1977 and Vietnam in 2009 have common characteristics to be favorable of achieving universal coverage with similarities of level of income, highly qualified administrative ability, tradition of solidarity, and strong political leadership although there are differences in distribution of population and structure of the economy. From a comparative perspective, Vietnam can consider the experience of Korea in implementing the mandatory enrollment approach, household unit of eligibility, design of contribution and benefit scheme, and resource allocation to health insurance for sustainable government subsidy to achieve and sustain the universal coverage of health insurance.

    The field research of oil conservation was conducted in developing countries, in particular, Vietnam where a steep increase in oil consumption is anticipated in the future. Energy conservation is the most effective direct measures to control combustion of fossil fuels, and an important issue to be promoted by all countries in the world to prevent global warming and reserve energy resources. In fiscal 1994, main industries in the northern part of Vietnam were researched. In fiscal 1995, the report meeting of plant survey results in the northern part and the technical seminar of energy-saving in industrial field were held, and plants around Ho Chi Minh City in the southern part of Vietnam were researched. Although Vietnam has recently acquired membership in ASEAN and is undergoing dramatic economic growth, has many problems in environmental measures. Japan has top-ranking results on energy-saving in industrial field, and the transfer of such superior technologies and techniques will greatly contribute to resource and global warming problems as well as pollution control measures in Vietnam. 13 refs., 25 figs., 26 tabs.

    Migrant beer promoters in Cambodia, Laos, Thailand, and Vietnam were surveyed to determine their experiences in accessing reproductive health care services in the cities of Phnom Penh, Vientiane, Bangkok, and Hanoi. A total of 7 health care institutions were chosen as popular with migrant beer promoters. Staff at these institutions provided information on the institution, and 390 beer promoters were surveyed about their experiences while accessing services. There were discrepancies between findings from the staff interviews and the experiences of the beer promoters. In general, the migrant women were satisfied with the cost, location, friendliness of the health care providers, and knowledge and skills of the providers. They were less positive about confidentiality and waiting times, though many still agreed that these were not an issue. Health care planners and providers should take note of the issues affecting access to reproductive health care services for migrant women when they design and implement services.
