    Background/Aims The goal of this study was to examine the reliability and validity of the Changsha version of the Montreal Cognitive Assessment (MoCA-CS) in ischemic cerebrovascular disease patients of Hunan Province, China, and to explore the optimal cutoff score for detecting vascular cognitive impairment-no dementia (VCI-ND) and vascular dementia (VD). Methods Three hundred and thirty-eight ischemic cerebrovascular disease patients (131 with normal cognition, 111 with VCI-ND, and 96 with VD) and 132 healthy controls were recruited. All participants accepted examination by the MoCA-CS, Mini-Mental State Examination (MMSE), and other related scales. A detailed neuropsychological battery was used for making a final cognitive diagnosis. SPSS 16.0 statistical software was used for reliability, validity examination, and optimal cutoff score detection. Results Cronbach's α of the MoCA-CS was 0.884, and test-retest and interrater reliability of the MoCA-CS were 0.966 and 0.926, respectively. MoCA-CS scores were highly correlated with MMSE scores (r = 0.867) and simplified intelligence quotients (r = 0.822). The results indicate that 1 point should be added for subjects with less than 6 years of education, and that the optimal cutoff score for detecting VCI-ND is 26/27 (sensitivity 96.1%, specificity 75.6%), whereas the optimal cutoff score for detecting VD is 16/17 (sensitivity 92.7%, specificity 96.3%). Conclusion The MoCA-CS has good reliability and validity, and is a useful cognitive screening instrument for detecting VCI in the Chinese population. PMID:23637698

    One of the main directions of technology development in the 21st century is the development and application of new materials, and the key to the development of the new material industry lies in the industrial technology innovation. The gross scale of the new material industry in Hunan Province ranks the first array in China. Based on the present situation of Hunan’s new material industry, three modes of technology innovation alliance are put forward in this paper, namely the government-driven mode, the research-driven and the market-oriented mode. The government-driven mode is applicable to the major technology innovation fields with uncertain market prospect, high risk of innovation and government’s direct or indirect intervention;the research-driven mode is applicable to the key technology innovation fields with a high technology content; and the market-oriented mode is applicable to the general innovation fields in which enterprises have demands for technology innovation but such innovation must be achieved via cooperative research and development.

    Huangshaping is one of the most important polymetallic deposits in the south of Hunan Province. Through field investigation, chemical analysis, observation under the optical microscope, energy spectrum analysis of the SEM and X-ray diffraction, the author made a technological mineralogical research of molybdenum on skarn-type ore, and the result shows that the ore containing molybdenum is mainly on the contact of the granite porphyry and the impure limestone in the lower carboniferous Shidengzi group. Besides molybdenum, the ore minerals contain scheelite, native bismuth, bismuthinite, magnetite and so on; and the gangue minerals are mainly andradite, fluorite and wollastonite. Part of the molybdenum exists in the scheelite in form of isomorphism, and there is an obvious negative correlation between MoO3 and WO3. The molybdenite granularity is mainly located in the 0.04~ 0.08mm area, which accounts for 29.5% of the total and is the finely disseminated ore. For samples of 70%, 90%, and 100% with the particle size of more than 200 meshes, the maximum recovery of the molybdenite are 75.15%, 86.45% and 91.25% respectively. So there will be a better use of molybdenum if we properly improve the grinded particle size of the comprehensive samples. As part of the molybdenum is distributed in the scheelite lattice, the actual recovery rate in this area may decline compared with the ideal value.

    Triage is implemented to facilitate timely and appropriate treatment of patients, and is typically conducted by senior nurses. Triage accuracy and consistency across emergency departments remain a problem in mainland China. This study aimed to investigate the current status of triage practice and knowledge among emergency nurses in Changsha, Hunan Province, China. A sample of 300 emergency nurses was selected from 13 tertiary hospitals in Changsha and a total of 193 completed surveys were returned (response rate=64.3%). Surveys were circulated to head nurses, who then distributed them to nurses who met the selection criteria. Nurses were asked to complete the surveys and return them via dedicated survey return boxes that were placed in discreet locations to ensure anonymity. Just over half (50.8%) of participants reported receiving dedicated triage training, which was provided by their employer (38.6%), an education organisation (30.7%) or at a conference (26.1%). Approximately half (53.2%) reported using formal triage scales, which were predominantly 4-tier (43%) or 5-tier (34%). The findings highlight variability in triage practices and training of emergency nurses in Changsha. This has implications for the comparability of triage data and transferability of triage skills across hospitals. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Hunan province is rich in agriculture products and their by-products. The processing and preservation of those products after porduction is an urgent problem to solve. However, radiation techniques can solve the problem of the processing and preservation of part of those products which can not be solved by normal ways. Only in Changsha area, the products such as leather and their products, dried and fresh fruit, medical equipments, industrial chemicals and so on, which can be provided to irradiate, weigh over 1 x 10 5 tons a year. In order to advance the research and application of radiation techniques in the province, over 40 units have been investigated in the province and other provinces. Since 1983, six informal discussions or demonstration meetings were held. 15 pieces of various reports and materials have been put forward. The necessity, possibility, size, place, development aim and united research of building a radiation centre have been scientificly demonstrated and a certain basis have been provided for building radiation centre

    The main objective of this study was to explore the prevalence and clinical characteristics of human coronavirus NL63 infection in hospitalized children with acute lower respiratory tract infection (ALRTI) in Changsha. Nasopharyngeal aspirates (NPA) samples were collected from 1185 hospitalized children with ALRTI at the People's Hospital of Hunan province, between September 2008 and October 2010. Reverse transcriptase polymerase chain reaction (RT-PCR) was employed to screen for coronavirus NL63, which is a 255 bp fragment of a part of N gene. All positive amplification products were confirmed by sequencing and compared with those in GenBank. The overall frequency of coronavirus NL63 infection was 0.8%, 6 (60%) out of the coronavirus NL63 positive patients were detected in summer, 2 in autumn, 1 in spring and winter, respectively. The patients were from 2 months to two and a half years old. The clinical diagnosis was bronchopneumonia (60%), bronchiolitis (30%), and acute laryngotracheal bronchitis (10%). Four of the 10 cases had critical illness, 4 cases had underlying diseases, and 7 cases had mixed infection with other viruses. The homogeneity of coronavirus NL63 with those published in the GenBank at nucleotide levels was 97%-100%. Coronavirus NL63 infection exists in hospitalized children with acute lower respiratory tract infection in Changsha. Coronavirus NL63 infections are common in children under 3 years of age. There is significant difference in the infection rate between the boys and the girls: the boys had higher rate than the girls. The peak of prevalence of the coronavirus NL63 was in summer. A single genetic lineage of coronavirus NL63 was revealed in human subjects in Changsha. Coronavirus NL63 may also be one of the lower respiratory pathogen in China.

    This study was conducted to clarify the knowledge and attitudes of Chinese university students regarding living organ donation and analyze the determinants impacting their decisions. A questionnaire was delivered to college students chosen by random assignment. The data was analyzed by Statistics Package for Social Science (SPSS) software. Of 434 participants, 49.8% indicated they would be willing to be living organ donors, 58.4% believed living organ donation could ease the organ shortage, 48.2% thought that the recovery rate of recipients of living organ donors transplants was equal to or even better than deceased donation, 62.4% designated relatives as their most probable recipients, 48.0% argued that partial compensation was an effective method to increase live organ donation, and 53.7% wished to donate through transplantation centers. According to univariate analysis, attitudes regarding the value of life, relationship between body integrity and health as well as body integrity and conventional culture were factors that impacted on an individual's decision. Students' knowledge of the value of living organ transplantation and their economic background were considered to be determinants of individual willingness. Furthermore, the operation's impact on quality of life and postoperative complications were additional concerns. Multivariate analysis indicated that other factors influencing students' willingness to donate included attitudes toward the relationship between body integrity and health, beliefs regarding body integrity and conventional culture, value of living donor organ transplantation, economic background of students, and anxiety about the impact on postoperative complications. Numerous students were willing to participate in living organ donation. At the same time, social education and advertisements for living organ donation were far from adequate, having little or no influence on the decision-making process.

    The Yangjiatan tungsten district at latitude 27??28??? N. and longitude 111??54???E. is located about 140 km southwest of the city of Changsha and 35 km northeast of the town of Shaoyang, southeast Hunan Province, People's Republic of China. The deposits, consisting largely of scheelite in veins (Wang, 1975), are contained in highly folded and faulted sedimentary rocks of Paleozoic, Mesozoic, and Cenozoic age intruded by granitic plutons that are circular in plan view. The major faults and folds trend in a northeasterly direction; whereas, the plutons are clustered in a more easterly trending band across the Landsat image. Landsat image E-2338-02202, acquired December 26, 1975, is number 470 in the "Landsat Image Atlas of the People's Republic of China" printed by the Publishing House of Geology in 1979. A computer-compatible tape of the image was analyzed and used as a demonstration project under a United Nations technical assistance program. Supervised classification of soils, rocks, and vegetation; band ratioing to detect limonite alteration; and edge enhancement were all conducted to demonstrate the flexibility and capability of interactive computer systems. Field evaluation of the results of this work will be conducted by colleagues of the Remote Sensing Center for Geology, Ministry of Geology, in China. ?? 1983.

    China has seen a proliferation of entertainment centres that are frequented by business people. Employees at these centres often are young, female rural-to-urban migrants who may be vulnerable to sexual violence and exploitation. Data for this study were collected using a self-administered survey among male and female employees in two high-end entertainment centres in Changsha, Hunan Province, China. We used logistic regression to examine predictors of violent and potentially exploitative experiences (partner violence, forced sex and transactional sex). Predictors included gender, ever having a same-sex partner, migration variables and employment characteristics. Participants reported high levels of partner violence (16.0% ever and 9.0% in the past 3 months) and forced sex (13.9% ever and 5.5% in the past 3 months). Nineteen percent reported sex work in the past 3 months. In the multivariate regressions, ever having had a same-sex partner was associated with higher odds of ever having experienced partner violence (odds ratio (OR)=7.8, Pgender nor migration status was associated with any of the outcomes. High-end entertainment centre workers in China are at risk for sexual violence and should be targeted with employment-based interventions.

    The fossil belemnoids described here were discovered from the Upper Permian Dalong Formation in Hunan province. There are nearly one hundred specimens, including one genus and one species. The diagnosis of the species is as follows: Genus: palaeobelemnopsis Chen, 1982; Species: Palaeobelemnosis sp. The guard is small and slender, about six times the maximum transverse diameter in length, with outline slightly hastate or fusiform. The maximum transverse diameter locates the border between the apical region and the stem region, and is nearly cycloid or slightly compressed in the anterior of the alveolus. The apical angle is about 70{degree}. The median ventral groove is wide and shallow, and is sometimes absent. Two dorso-lateral grooves are apparent and extending from the alveolus to the apex. The Phragmocone is slender. The outer shape of the guard is very similar to that of P. sinensis and P. minor. Nevertheless, this species differs from the two latters in having many transverse lines covering on the whole surface of the guard. Because all of these specimens are fossils of external mold and no inner structures have been preserved except a piece of siphuncle remains, the species is not given a new species name. Permian belemnoids are rarely found and the Palaeobelemnopsis is a primitive genus of belemnoids, therefore these specimens have important significance for research on the origin of COLEOIDEA. 4 refs., 3 figs.

    Major efforts have been made to improve the health care system in Hunan province, China. The aims of this study were to assess whether and to what extent these efforts have impacted on gender and regional disparities of Tuberculosis (TB) incidence in recent years, especially for less developed areas. We obtained data from the 2005-2009 China Information System for Disease Control and Prevention (CISDCP)to conduct this study in Hunan province. Counties within the province were divided into four regions according to quartiles based on the 2007 per capita GDP. Index of Disparity (ID) and Relative Index of Inequality (RII) were used to measure the disparities of TB incidence in relation to gender and region. Bootstrap technique was used to increase the precision. The average annual incidence of TB was 111.75 per 100,000 in males and 43.44 per 100 000 in females in Hunan. The gender disparity was stable, with ID from 42.34 in 2005 to 43.92 in 2009. For regional disparity, ID, RII (mean) and RII (ratio) decreased significantly from 2005 to 2009 in males (P China, regional disparity in relation to incidence of TB decreased significantly, but the gender disparity remains in the Hunan province.

    In this paper, a hierarchy index system suitable for catastrophe progression method was constructed to comprehensively analyze and evaluate the status of ecological land construction in Changsha City in 2007. Based on the evaluation results, the irrationalities of the distribution pattern of Changsha urban ecological land were discussed. With the support of geographic information system (GIS), the ecological corridors of the urban ecological land were constructed by using the 'least-cost' modeling, and, in combining with conflict analysis, the optimum project of the urban ecological land was put forward, forming an integrated evaluation system. The results indicated that the ecological efficiency of urban ecological land in Changsha in 2007 was at medium level, with an evaluation value being 0.9416, and the quantitative index being relatively high but the coordination index being relatively low. The analysis and verification with software Fragstats showed that the ecological efficiency of the urban ecological land after optimization was higher, with the evaluation value being 0.9618, and the SHDI, CONTAG, and other indices also enhanced.

    Full Text Available Abstract Background Injection drug use (IDU is one of the major modes of HIV transmission in China. Drug use is illegal in China, all identified drug users are registered by Public Security Bureau, and most were sent to detention; most detainees engaged in high risk behaviours. In order to well understand the HIV/AIDS knowledge among detainees, a survey was conducted in different detention settings in Hunan province in 2008 to assess knowledge and attitudes about HIV among detainees and to provide useful information for HIV prevention and intervention strategies in detention centers. Methods A cross-sectional survey was conducted in 10 detentions in Hunan province, China, and demographic information along with knowledge and attitude of HIV/AIDS was collected through standardized interviews. Descriptive statistics were used to describe HIV knowledge, attitudes, and education services among detainees. Results There were 956 detainees interviewed from 10 detention centers. The male to female ratio was 2.24:1. The majority detainees received nine years of compulsory education, accounting for 51.5%. There were nine questions to assess HIV/AIDS knowledge of detainees, and 35.7% of those surveyed answered all nine questions correctly. There were 92.3% (882/956 who consented to be informed about the HIV antibody test results when tested, and 81% (774/956 elected that their family members were also informed. All detention centers had an organized HIV/AIDS education program. Conclusion This study gives us an overview about HIV/AIDS knowledge in detention in Hunan province, and all detention sites in the study provided HIV/AIDS intervention services among detainees that focused on HIV/AIDS knowledge, attitude, and health behaviors.

    Our aim was to (1) survey public' perception and attitudes toward organ donation and (2) analyze the relationship between knowledge, attitudes, and willingness to donate. We developed a questionnaire, and conducted the survey with stratified random sampling. Overall, 600 residents, aged ≥18 who resided in Hunan, and 600 undergraduates from 3 universities in Hunan were surveyed randomly. For this study, 1085 valid questionnaires were completed, with a response rate of 90.4%. Of the 1085 participants, 581 (53.5%) were students, 504 (46.5%) were residents, and 519 (47.8%) were male and 566 (52.2%) female. The mean accuracy rate was 71.96%, and the students' mean accuracy rate was slightly higher than that of the resident population (73.06% vs 70.68%, respectively). The results showed that 82.2% of public support organ donation, and 53.5% were willing to donate their organs after death. Students scored higher than the residents (88% vs 75.6% and 55.6% vs 51.2%). Nearly 1.8% felt that organ donation was against their religion, 14.9% thought it was important to ensure the integrity of the body, 71.7% agreed that organ donation allowed a positive outcome after a person's death, and 61.5% agreed that organ donation represented a continuation of life, to help families cope with grief. Age and gender were related to attitudes. Public knowledge of organ donation and their attitudes were correlated positively (r = 0.666). Public knowledge of organ donation is poor, biased, and incomplete, and based on television, movies, and communication networks. Positive attitudes toward donation displayed in the surveys were not matched by actual organ donation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Chlamydia abortus is an obligate intracellular Gram-negative bacteria, which can infect animals and human, including goats. However, little information on C. abortus infection is available in goats in Hunan province, subtropical China. To investigate the seroprevalence and risk factors of C. abortus infection in goats in Hunan province, China, a total of 911 goat blood samples were collected randomly from 14 herds having number of goats ranging from 1000 to 3000 from March 2014 to December 2015. Seropositive animals were found in 11 out of 14 (78.57%) goat herds with seroprevalence ranging from 0.00% to 29.94% in individual herds. Overall, the seroprevalence of C. abortus infection was different among regions (southern Hunan: 1.78%; northeast Hunan: 5.47%; and west Hunan: 15.29%), gender (male: 4.58% and female: 9.10%), seasons (spring: 5.97%; summer: 2.61%; autumn: 16.88%; and winter: 10.94%), and ages (year ≤1: 2.39%; 1 3: 17.57%). Risk factors for C. abortus infection were associated with region, season, and age in this study. To our knowledge, this is the first document to demonstrate the existence of C. abortus infection in goats, and the seroprevalence was 8.45% out of 911 goats in Hunan province.

    Objective To evaluate current club drug use and its potential association with the transmission of HIV/STD among Changsha men who have sex with men (MSM). Method A cross-sectional survey was conducted by using self-administered questionnaires including information regarding socio-demographics, club drug use, high-risk behaviors, and HIV/STD infections. Multiple methods including venue-based, peer referral using “snowball” techniques, and internet advertisements were used to recruit study participants. Results Of the 826 participants, 177 (21.4%) reported that they had used club drugs at some time before or during sex in the past six months. MSM with young age, low education level, and seeking partners through the internet or bars were the main population who used drugs. Poppers were the most common drug used among Changsha MSM. The prevalence of HIV, syphilis, and herpes simplex virus-2 were higher among drug users. There were no significant differences in unprotected sexual intercourse and condom use between drug users and non-users. Compared with non-users, risk behaviors such as group sex, multiple sex partners, and sex with foreigners were more frequent among drug users. Conclusion Club drug use is common among Changsha MSM, and is related to unsafe sex activities and HIV/STD infection. It is necessary to build novel targeted HIV prevention strategies to monitor and reduce club drug use among MSM. PMID:25950912

    Tobacco retail sales are prohibited within 100 m of schools in many large cities in China. However, little is known about the enforcement of this zoning regulation. The objectives of this study were to estimate tobacco retailers' compliance with the regulation, examine the density of tobacco retail stores, describe the types of tobacco products sold in stores and how they are marketed, and determine if there are displays of warning messages in retail stores around schools and in neighbourhoods in Changsha, China. Tobacco retail stores located within 200 m of 36 schools and 36 residential neighbourhoods were audited by trained students with a validated audit form. On average, there were about 3 tobacco retail stores within 100 m of the front entrance of schools. The density of the stores and the types of tobacco products sold in the stores were similar near schools and in neighbourhoods. Over one-fourth of the stores had exterior tobacco advertisements. Interior advertising was slightly less prevalent, and it was most prevalent among tobacco shops (62.5%). Tobacco displays that target children were pervasive, with about 83% of tobacco retail stores displaying cigarettes within 1 m of the floor and 59% displaying cigarettes within 0.3 m of toys and candy. About 40% of stores within 100 m of a school had a visible retail licence. Only 19.6% of the stores had a 'smoke-free' sign and 22.2% had a 'no sales to minors' sign. We observed low enforcement of the regulation that bans tobacco retail sales near schools and high prevalence of tobacco displays that target children in Changsha, China. Chinese officials should act to effectively enforce the regulation bans of tobacco sales near schools. In addition, regulations are urgently needed to limit tobacco marketing practices at the point of sale, especially those targeting youth. Published by the BMJ Publishing Group Limited.

    International Nuclear Information System (INIS)

    1985-01-01

    A survey of the natural external radiation level in Hunan Province is reported. The measurements were performed with FD-71 scintillation radiometers. On the basis of measurements at about 1,600 locations, the contribution from cosmic radiation is found to be 3.0 x 10 -8 Gy.h -1 , and the average absorbed dose rates in air from terrestrial γ-radiation for outdoors, indoors and roads are determined to be 9.2, 13.1 and 9.0 x 10 -8 Gy.h -1 , respectively. The γ-radiation indoors is markedly higher than that outdoors by a factor of 1.42. The lowest γ-radiation level is found in the sedimentary plain around Donting Lake, while the highest absorbed dose rates in air from terrestrial radiation are observed in some areas with exposed granites. The indoor γ-radiation in brick houses is markedly higher than that in wooden houses. Tarred roads have evidently lower radiation level than sand-gravel roads or concrete roads. The annual effective dose equivalents to the population from cosmic and terrestrial sources are 0.256 and 0.756 mSv, respectively, with a total value of 1.012 mSv

    In order to estimate the mass concentrations of benzene (B), toluene (T), ethylbenzene (E) and xylenes (X) inside air environment of buses and to analyze the influencing factors of the BTEX pollution levels, 22 public buses were investigated in Changsha, China. The interior air was collected through activated charcoal adsorption tubes and then the air samples were analyzed with thermally desorbed gas chromatograph. The mass concentrations ranged from 21.3 to 106.4 {mu}g/m{sup 3} for benzene, from 53.5 to 266.0 {mu}g/m{sup 3} for toluene, from 19.6 to 95.9 {mu}g/m{sup 3} for ethylbenzene and from 46.9 to 234.8 {mu}g/m{sup 3} for xylenes. Their mean values were 68.7, 179.7, 62.5 and 151.8 {mu}g/m{sup 3}, respectively. The rates of buses tested where the interior concentrations exceeded the limit levels of Chinese Indoor Air Quality Standard were 45.5% for toluene and 13.6% for xylenes. The BTEX levels increased when in-car temperature or relative humidity rose, and decreased when car age or travel distance increased. The BTEX concentrations were higher in leather trims buses than in non-leather trims ones, in air-conditioned buses than in non-air-conditioned ones, and in high-grade buses than in low-grade ones. According to the analysis of multiple linear regression equation, car age and in-car temperature were two most important factors influencing the BTEX pollution levels in the cabins of public buses.

    To realize the influence of climatic changes on the transmission of hemorrhagic fever with renal syndrome (HFRS), and to explore the adoption of climatic factors in warning HFRS. A total of 2171 cases of HFRS and the synchronous climatic data in Changsha from 2000 to 2009 were collected to a climate-based forecasting model for HFRS transmission. The Cochran-Armitage trend test was employed to explore the variation trend of the annual incidence of HFRS. Cross-correlations analysis was then adopted to assess the time-lag period between the climatic factors, including monthly average temperature, relative humidity, rainfall and Multivariate Elño-Southern Oscillation Index (MEI) and the monthly HFRS cases. Finally the time-series Poisson regression model was constructed to analyze the influence of different climatic factors on the HFRS transmission. The annual incidence of HFRS in Changsha between 2000 - 2009 was 13.09/100 000 (755 cases), 9.92/100 000 (578 cases), 5.02/100 000 (294 cases), 2.55/100 000 (150 cases), 1.13/100 000 (67 cases), 1.16/100 000 (70 cases), 0.95/100 000 (58 cases), 1.40/100 000 (87 cases), 0.75/100 000 (47 cases) and 1.02/100 000 (65 cases), respectively. The incidence showed a decline during these years (Z = -5.78, P Climate factors significantly influence the incidence of HFRS. If the influence of variable-autocorrelation, seasonality, and long-term trend were controlled, the accuracy of forecasting by the time-series Poisson regression model in Changsha would be comparatively high, and we could forecast the incidence of HFRS in advance.

    With the fast development of remote sensing technology, combining forest inventory sample plot data and remotely sensed images has become a widely used method to map forest carbon density. However, the existence of mixed pixels often impedes the improvement of forest carbon density mapping, especially when low spatial resolution images such as MODIS are used. In this study, MODIS images and national forest inventory sample plot data were used to conduct the study of estimation for forest carbon density. Linear spectral mixture analysis with and without constraint, and nonlinear spectral mixture analysis were compared to derive the fractions of different land use and land cover (LULC) types. Then sequential Gaussian co-simulation algorithm with and without the fraction images from spectral mixture analyses were employed to estimate forest carbon density of Hunan Province. Results showed that 1) Linear spectral mixture analysis with constraint, leading to a mean RMSE of 0.002, more accurately estimated the fractions of LULC types than linear spectral and nonlinear spectral mixture analyses; 2) Integrating spectral mixture analysis model and sequential Gaussian co-simulation algorithm increased the estimation accuracy of forest carbon density to 81.5% from 74.1%, and decreased the RMSE to 5.18 from 7.26; and 3) The mean value of forest carbon density for the province was 30.06 t · hm(-2), ranging from 0.00 to 67.35 t · hm(-2). This implied that the spectral mixture analysis provided a great potential to increase the estimation accuracy of forest carbon density on regional and global level.

    To analyze the status quo of quantitative classification in Hunan Province catering industry, and to discuss the countermeasures in-depth. According to relevant laws and regulations, and after referring to Daily supervision and quantitative scoring sheet and consulting experts, a checklist of key supervision indicators was made. The implementation of quantitative classification in 10 cities in Hunan Province was studied, and the status quo was analyzed. All the 390 catering units implemented quantitative classified management. The larger the catering enterprise, the higher level of quantitative classification. In addition to cafeterias, the smaller the catering units, the higher point of deduction, and snack bars and beverage stores were the highest. For those quantified and classified as C and D, the point of deduction was higher in the procurement and storage of raw materials, operation processing and other aspects. The quantitative classification of Hunan Province has relatively wide coverage. There are hidden risks in food security in small catering units, snack bars, and beverage stores. The food hygienic condition of Hunan Province needs to be improved.

    To study the population data of Y-chromosome STRs (Y-STRs) of Han population resided in Hunan province, we analyzed haplotypes of 26 Y-STRs (DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS481, DYS533, DYS549, DYS570, DYS576, DYS635, DYS643, DYS388, DYS449, DYS460, and YGATAH4) in 310 unrelated male individuals using a commercially available Goldeneye® DNA ID 26Y system. The calculated average gene diversity values ranged from 0.4211 to 0.9590 for DYS438 and DYS385a/b loci, respectively. The discriminatory capacity was 96.77 % with 300 observed haplotypes. Population relationships between Hunan Han and eight other populations available from Y-chromosome haplotype reference database (YHRD) were compared. The results showed that the Han population resided in the Hunan district is significantly different from other populations. Our results also indicated that these 26 Y-STR loci were highly genetically polymorphic in the Hunan Han population and of great value in forensic application.

    Improving the carbon efficiency of crop production systems is one of the important ways to realize low-carbon agriculture. A life cycle assessment approach and input-output calculation method was applied for a double-rice production system in the Hunan Province. Based on statistical data of crop yield and investment in the production system in the period from 2004 to 2012, carbon emission, carbon absorption, carbon efficiency and their dynamic changes of the double rice production systems were estimated. The results showed that the average of annual carbon emission from 2004 to 2012 was 656.4 x 10(7) kg CE. Carbon emissions from production and transport of fertilizer and pesticide accounted for a majority of agricultural input carbon emissions, approximately 70.0% and 15.9%, respectively. The carbon emission showed a decreasing trend from 2004 to 2012 in the Hunan Province, with an annual reduction rate of 2.4%, but the carbon emission intensity was in a trend of increase. The average of annual carbon absorption was 1547.0 x 10(7) kg C. The annual carbon absorption also showed a decreasing trend from 2004 to 2012 in Hunan Province, with an average annual reduction rate of 1.2%, and the carbon absorption intensity showed a trend of increase. Furthermore, production efficiency of carbon showed a slow upward trend. The economic efficiency of carbon showed a larger increasing rate with time, with an average annual growth rate of 9.9%. Ecological efficiency of carbon was stable and low, maintained at about 2.4 kg C . kg-1 CE. It indicated that the integrated carbon efficiency of Hunan double rice crop production system improved slowly with time and the key to improve the carbon efficiency of double rice production systems lies in reducing the rates of nitrogen fertilizer and pesticide, and improving their use efficiencies.

    Semi-volatile organic compounds (SVOCs) derived from plastic pipes widely used in water distribution definitely influence our daily drinking water quality. There are still few scientific or integrated studies on the release and degradation of the migrating chemicals in pipelines. This investigation was carried out at field sites along a pipeline in Changsha, China. Two chemicals, 2, 4-tert-buthylphenol and 1, 3-diphenylguanidine, were found to be migrating from high density polyethylene (HDPE) pipe material. New pipes released more of these two compounds than older pipes, and microorganisms living in older pipes tended to degrade them faster, indicating that the aged pipes were safer for water transmission. Microorganism degradation in water plays a dominant role in the control of these substances. To minimize the potential harm to human, a more detailed study incorporating assessment of their risk should be carried out, along with seeking safer drinking pipes.

    To investigate the trend and related determinants of cigarette smoking on experimental smokers among undergraduate students in Changsha. Stratified sampling method was adopted and 3600 undergraduate students from grade 1 to 3 in Changsha city were investigated through a self-administered questionnaire. All the experimental smokers during the last month were selected and divided into two groups based on the present smoking status. χ(2) test and logistic regression analysis were used to compare the differences of cigarette smoking among subpopulations and to explore the determinants. Among the 1550 experimental smokers of undergraduate students, the prevalence of cigarette smoking was 30.8% (95%CI: 28.5 - 33.1). Students from the second-class (OR = 2.367) or the third-class universities (OR = 2.562) were more likely to adopt smoking behavior than those from top universities. Students majored in sports or arts (OR = 2.456) were significantly more inclined to smoke than the liberal arts students. Students whose father were cadres (OR = 1.602) were more likely to become smokers than those whose fathers were workers. Students being males (OR = 7.386), having high monthly expenses (OR = 1.139), with positive attitude to smoking benefits (OR = 1.140) were risk factors for smoking. Number of smoking members in the family (OR = 1.801) was significantly associated with the prevalence of cigarette smoking. Knowledge on diseases caused by smoking (OR = 0.806) was protecting factor to smoking among the experimental smokers. Those experimental smokers among undergraduate students might become smokers and the determinants of cigarette smoking behavior would include: ranking of universities, students' major, gender, father's occupation, amount of pocket money, number of smoking members in the family, knowledge about smoking, the attitude to the benefit of smoking.

    To explore the relationship between use of rush poppers and HIV infection, and associated factors among men who have sex with men in Changsha. A cross-sectional study was conducted in Changsha from April to December, 2014. Men who have sex with men who came for HIV counseling and testing services were invited to fill out a survey. A total of 608 MSM were finally recruited. The survey included socio-demographic characteristics, sexual roles, sexual behaviors in last 6 months and rush poppers use, HIV infection among MSM. After finishing the questionnaire, 5 ml blood was also drawn for HIV testing. Chi-square test or Fisher probabilities was used to compare usage of rush poppers and HIV antibody positive rate among MSM who had different characteristics and sexual behaviors. Multi-factor unconditioned logistic regression model was used to explore related factors about rush poppers use and HIV infection of MSM. Among 608 MSM, 29.8% (181) said they ever used rush poppers, and 13.3% (81 cases) were HIV positive. Among MSM who ever used rush poppers, 18.8% (34/181) were HIV positive; While among those who never used rush poppers, 10.5% (45/427) were HIV positive (χ(2)=7.65,P=0.006). Compared with MSM who had no For One Night sex in the last 6 months,OR (95% CI) value of MSM who had 6-10 times For One Night sexes in last 6 months to use rush poppers was 4.32 (1.77-10.57). Compared with MSM who self-identified as top,OR (95% CI) value of MSM who self-identified as bottom or versatile using rush poppers were 2.99 (1.53-5.86), or 3.60 (2.13-6.09). Compared with MSM who self-identified as top, OR (95% CI) value of MSM who self-identified as bottom or versatile to infect HIV were 3.19 (1.35-7.58), or 2.33 (1.12-4.85). Compared with MSM who used condoms at every anal sex,OR (95% CI) value of MSM who used condoms sometimes or never used to infect HIV were 1.93 (1.12-3.35) or 1.87 (0.64-5.50). Compared with MSM who never used rush poppers,OR (95% CI) value of MSM who ever used

    Jishou and Huaihua, two cities in the west of Hunan Province, had suffered from severe floods because of long-lasting and heavy rainfall during the end of June and July 2012. However, the Disability Adjusted of Life Years (DALYs) of bacillary dysentery caused by the floods have not been examined before. The study aimed to quantify the impact of the floods on the burden of bacillary dysentery in Hunan, China. A unidirectional case-crossover study was firstly conducted to determine the relationship between daily cases of bacillary dysentery and the floods in Jishou and Huaihua of Hunan Province in 2012. Odds ratios (ORs) estimated by conditional logistic regression were used to quantify the risk of the floods on the disease. The years lived with disability (YLDs) of bacillary dysentery attributable to floods were then estimated based on the WHO framework to calculate potential impact fraction in the Burden of Disease study. Multivariable analysis showed that floods were significantly associated with an increased risk of the number of cases of bacillary dysentery (OR=3.270, 95% CI: 1.299-8.228 in Jishou; OR=2.212, 95% CI: 1.052-4.650 in Huaihua). The strongest effect was shown with a 1-day lag in Jishou and a 4-day lag in Huaihua. Attributable YLD per 1000 of bacillary dysentery due to the floods was 0.0296 in Jishou and 0.0157 in Huaihua. Our study confirms that floods have significantly increased the risks of bacillary dysentery in the study areas. In addition, a sudden and severe flooding with a shorter duration may cause more burdens of bacillary dysentery than a persistent and moderate flooding. Public health preparation and intervention programs should be taken to reduce and prevent a potential risk of bacillary dysentery epidemics after floods. Copyright © 2016 Elsevier B.V.

    Stem-pitting (SP) is the main type of citrus tristeza virus (CTV) that causes severe damage to citrus trees, especially those of sweet orange, in Hunan province, China. Understanding the local CTV population structure should provide clues for effective mild strain cross-protection (MSCP) of the SP strain of CTV. In this study, markers for the p23 gene, multiple molecular markers (MMMs), and sequence analysis of the three silencing suppressor genes (p20, p23 and p25) were employed to analyze the genetic diversity and genotype composition of the CTV population based on 51 CTV-positive samples collected from 14 citrus orchards scattered around six major citrus-growing areas of Hunan. The results indicated that the CTV population structure was extremely complex and that infection was highly mixed. In total, p23 gene markers resulted in six profiles, and MMMs demonstrated 25 profiles. The severe VT and T3 types appeared to be predominantly associated with SP, while the mild T30 and RB types were related to asymptomatic samples. Based on phylogenetic analysis of the amino acid sequences of p20, p23 and p25, 19 representative CTV samples were classified into seven recently established CTV groups and a potentially novel one. A high level of genetic diversity, as well as potential recombination, was revealed among different CTV isolates. Five pure SP severe and two pure mild strains were identified by genotype composition analysis. Taken together, the results update the genetic diversity of CTV in Hunan with the detection of one possible novel strain, and this information might be applicable for the selection of appropriate mild CTV strains for controlling citrus SP disease through cross-protection.

    In this study, we focused on measuring levels of nurse burnout and job dissatisfaction in the daily practice of nurses in Hunan province, China, analyzed factors related to nurse burnout and job dissatisfaction, and explored the relationship between them. Previous studies have shown a high level of burnout and job dissatisfaction among nurses worldwide. A cross-sectional survey of 1100 nurses was conducted. The nurses worked at 20 hospitals in 11 cities and counties throughout China's Hunan province. Nurse burnout was measured by the Maslach Burnout Inventory. Nurse-rated job dissatisfaction was described using a four point scale, and work environment was measured using the Nursing Work Index - Practice Environment Scale. The results showed that nurses had high burnout scores and were dissatisfied with their jobs. Staffing, work environment, and work hours were all significantly associated with nurse burnout and job dissatisfaction. Adequate staffing, improved work environment, and reasonable work hours are related to decreasing nurse burnout and job dissatisfaction. © 2015 Wiley Publishing Asia Pty Ltd.

    To construct prediction model for health workforce and hospital beds in county hospitals of Hunan by multiple linear regression. We surveyed 16 counties in Hunan with stratified random sampling according to uniform questionnaires,and multiple linear regression analysis with 20 quotas selected by literature view was done. Independent variables in the multiple linear regression model on medical personnels in county hospitals included the counties' urban residents' income, crude death rate, medical beds, business occupancy, professional equipment value, the number of devices valued above 10 000 yuan, fixed assets, long-term debt, medical income, medical expenses, outpatient and emergency visits, hospital visits, actual available bed days, and utilization rate of hospital beds. Independent variables in the multiple linear regression model on county hospital beds included the the population of aged 65 and above in the counties, disposable income of urban residents, medical personnel of medical institutions in county area, business occupancy, the total value of professional equipment, fixed assets, long-term debt, medical income, medical expenses, outpatient and emergency visits, hospital visits, actual available bed days, utilization rate of hospital beds, and length of hospitalization. The prediction model shows good explanatory and fitting, and may be used for short- and mid-term forecasting.

    To analyze the incidence of long (short) PR interval in electrocardiogram among healthy people in Changsha and the clinical significance.
 Twelve-lead body surface electrocardiogram was taken to measure the heart rates and PR intervals from 4 025 healthy individuals (age range from 6 min after birth to 83 years old) who performed physical examination from Jan, 1993 to Dec, 2012 in the Second Xiangya Hospital, Central South University. Statistics were analyzed by SPSS 16.0.
 The total incidence of short PR interval was 19.65% (791/4 025). The age group from birth to 13 years old had a higher incidence than the other age groups (χ2=432, PPR intervals was 3.58% (144/4 025). The 1 year-old group had the highest incidence (6.74%), which decreased with the increase of age. The lowest incidence of long PR intervals occurred in the age group from 14-17 years old, which gradually increased after 50 years old. There were no significant differences in long (short) PR intervals between the gender (P>0.05).
 The incidence of long (short) PR intervals varies in different age groups of healthy people. The incidences of long (short) PR intervals in children before 10 years old are higher than those in adults, especially the short PR intervals, as a result of the heart rate affected by childhood autonomic nervous function and the change in atrial volume with age. Adults have long (short) PR interval should be regularly followed-up to prevent cardiovascular events.

    Human rhinovirus (HRV) is a causative agent of acute respiratory tract infections. This study analyzed the prevalence and clinical characteristics of three HRV groups (HRV-A, -B, and -C) among 1,165 children aged 14 years or younger who were hospitalized with acute lower respiratory tract infection in China. PCR or reverse transcription-PCR was performed to detect 14 respiratory viruses in nasopharyngeal aspirates collected from September 2007 to August 2008 in Changsha, China. HRV was detected in 202 (17.3%) of the 1,165 children; 25.3% of the HRV-positive children were 13-36 months of age (χ(2)  = 22.803, P = 0.000). HRV was detected year round and peaked between September and December. Fifty-three percent of the HRV-positive samples were also positive for other respiratory viruses; respiratory syncytial virus (RSV) was the most common secondary virus. Phylogenetic analysis using the VP4/VP2 region grouped the HRV-positive strains as follows: 101 HRV-A (50.0%), 21 HRV-B (10.4%), and 80 HRV-C (39.6%). HRV-A infections occurred predominantly in spring and autumn, and the peak prevalence of HRV-C was in early winter and late autumn. HRV-B infections were less common in spring (χ(2)  = 31.914, P = 0.000). No significant difference in clinical severity or presentation was found between patients with HRV single infection and HRV co-detections. Furthermore, the clinical characterizations did not differ among the three HRV species. These results suggest that HRV-C is an important viral agent along with HRV-A and HRV-B and that among hospitalized children with acute lower respiratory tract infection in China, the three HRV genotypes have similar clinical characteristics. © 2014 Wiley Periodicals, Inc.

    To explore the epidemiological and clinical features of different human metapneumovirus (hMPV) genotypes in hospitalized children. Reverse transcription polymerase chain reaction (RT-PCR) or PCR was employed to screen for both hMPV and other common respiratory viruses in 2613 nasopharyngeal aspirate specimens collected from children with lower respiratory tract infections from September 2007 to February 2011 (a period of 3.5 years). The demographics and clinical presentations of patients infected with different genotypes of hMPV were compared. A total of 135 samples were positive for hMPV (positive detection rate: 5.2%). Co-infection with other viruses was observed in 45.9% (62/135) of cases, and human bocavirus was the most common additional respiratory virus. The most common symptoms included cough, fever, and wheezing. The M gene was sequenced for 135 isolates; of these, genotype A was identified in 72.6% (98/135) of patients, and genotype B was identified in 27.4% (37/135) of patients. The predominant genotype of hMPV changed over the 3.5-year study period from genotype A2b to A2b or B1 and then to predominantly B1. Most of clinical features were similar between patients infected with different hMPV genotypes. These results suggested that hMPV is an important viral pathogen in pediatric patients with acute lower respiratory tract infection in Changsha. The hMPV subtypes A2b and B1 were found to co-circulate. The different hMPV genotypes exhibit similar clinical characteristics. © 2015 Wiley Periodicals, Inc.

    To determine the prevalence of dyslipidemia in students from the primary and middle schools and the influential factors, and to provide evidence for the prevention and control of dyslipidemia and relevant chronic diseases in primary and middle schools. 
 Methods: A total of 2 028 students aged 7 to 17 from the primary and middle schools in Changsha were selected by stratified random cluster sampling. The contents of the study included questionnaire survey, physical measurement and blood tests for fasting blood triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels. Non-high-density lipoprotein cholesterol (non-HDL-C) level was calculated by TC level minus HDL-C level. Chi-square test and non-conditional logistic regression model were used to analyze the factors that contributed to dyslipidemia.
 Results: The dyslipidemia rate was 18.6%, and the abnormal rates of TG, TC, LDL-C, non-HDL-C and HDL-C were 6.8%, 5.6%, 2.3%, 4.2% and 8.6%, respectively. By chi-square test, the dyslipidemia rate in students with different ages, home locations, BMI groups, central obesity, time on watching TV or playing computer per day, and daily sleep time was statistically significant. Non-conditional logistic regression analysis showed that home location for the city (OR=1.332), overweight (OR=1.548), obesity (OR=2.201), central obesity (OR=1.695), watching TV or playing computer for more than 2 hours per day (OR=1.357), daily sleep time longer than 11 hours (OR=2.518) were the risk factors for dyslipidemia in students from the primary and middle schools. 
 Conclusion: Nearly 1/5 primary and middle school students show dyslipidemia, which is associated with obesity and other bad behaviors.

    Full Text Available Relapse among abstinent drug users is normal. Several factors are related to relapse, but it remains unclear what individuals' actual life circumstances are during periods of abstinence, and how these circumstances facilitate or prevent relapse.To illuminate drug users' experiences during abstinence periods and explore the real-life catalysts and inhibitors contributing to drug use relapse.Qualitative in-depth interviews were conducted with 20 drug users recruited from a compulsory isolated drug rehabilitation center in Changsha. The interviews were guided by open-ended questions on individuals' experiences in drug use initiation, getting addicted, treatment history, social environment, abstinence, and relapse. Participants were also encouraged to share their own stories. Interviews were digitally recorded and fully transcribed. The data of 18 participants who reported abstinence experiences before admission were included in the analyses. The data were analyzed using a thematic analysis with inductive hand coding to derive themes.Most drug users were able to successfully abstain from drugs. During abstinence, their lives were congested with challenges, such as adverse socioeconomic conditions, poor family/social support, interpersonal conflicts, and stigma and discrimination, all of which kept them excluded from mainstream society. Furthermore, the police's system of ID card registration, which identifies individuals as drug users, worsened already grave situations. Relapse triggers reported by the participants focused mainly on negative feelings, interpersonal conflicts, and stressful events. Craving was experienced but not perceived as a relapse trigger by most participants.This study of in-depth interview with drug users found evidence of situations and environments they live during abstinence appear rather disadvantaged, making it extremely difficult for them to remain abstinent.

    Money boys with inconsistent condom use (less than 100% of the time) are at high risk of infection by human immunodeficiency virus (HIV) or sexually transmitted infection (STI), but relatively little research has examined their risk behaviors. We investigated the prevalence of consistent condom use (100% of the time) and associated factors among money boys. A cross-sectional study using a structured questionnaire was conducted among money boys in Changsha, China, between July 2012 and January 2013. Independent variables included socio-demographic data, substance abuse history, work characteristics, and self-reported HIV and STI history. Dependent variables included the consistent condom use with different types of sex partners. Among the participants, 82.4% used condoms consistently with male clients, 80.2% with male sex partners, and 77.1% with female sex partners in the past 3 months. A multiple stepwise logistic regression model identified four statistically significant factors associated with lower likelihoods of consistent condom use with male clients: age group, substance abuse, lack of an "employment" arrangement, and having no HIV test within the prior 6 months. In a similar model, only one factor associated significantly with lower likelihoods of consistent condom use with male sex partners was identified in multiple stepwise logistic regression analyses: having no HIV test within the prior six months. As for female sex partners, two significant variables were statistically significant in the multiple stepwise logistic regression analysis: having no HIV test within the prior 6 months and having STI history. Interventions which are linked with more realistic and acceptable HIV prevention methods are greatly warranted and should increase risk awareness and the behavior of consistent condom use in both commercial and personal relationship. © 2015 International Society for Sexual Medicine.

    The concentrations of radon and its daughters in air of the dugouts was reported. This survey was made in three cities of Changsha, Hengyang and Zhuzhou. In dugouts which are used for cultivation of mushrooms (category I) or which have been reconstructed as hotels and the places for recreation (category II), the average concentration of radon and its daughter were found to be 0.451 Bq/l (12.2 pCi/l) and 0.872 μJ/m 3 (0.0419 WL) in Changsha, 0.710 Bq/l (19.2 pCi/l) and 1.47 μJ/m 3 (0.0709 WL) in Hengyang and 0.236 Bq/l (6.39 pCi/l) and 0.418 μJ/m 3 (0.0201 WL) in Zhuzhou, respectively. However, in those dugouts which have been reconstructed as the places for recreation the averange concentration of radon and its daughters were obtained to 0.566 Bq/l (15.3 pCi/l) and 0.940 μJ/m 3 (0.0452 WL) in Changsha, 1.10 Bq/l (29.8 pCi/l) and 2.83 μJ/m 3 (0.136 WL) in Hengyang and 0.511 Bq/l (13.8 pCi/l) and 0.982 μJ/m 3 (0.0472 WL) in Zhuzhou. For γ-rays, the range of exposure rate was 6-22 μR/h with a mean of 12 μR/h. The effective dose equivalent for persons working in these dugouts was estimated and some measures for radiation protection were suggested

    During 2012, Changsha experienced a large outbreak of hand, foot, and mouth disease (HFMD), resulting in 25,438 cases, including 42 severe cases and eight deaths. Seven hundred and forty-six clinical specimens were collected from hospital-based surveillance for HFMD in 2012. The detection and genotyping of enterovirus were performed by real-time RT-PCR and sequencing of the VP1 regions; phylogenetic analysis was performed based on the VP1 sequences. A total of 545 (73.1%) enterovirus-positive samples were identified, with the most frequently presenting serotype being enterovirus 71 (EV-71; n=364, 66.8%), followed by coxsackievirus A16 (CV-A16; n=84, 15.4%), CV-A6 (n=22, 4.0%), and CV-A10 (n=19, 3.5%). Most of the affected patients were children aged ≤5 years (n=524, 96.1%). EV-71 was the major pathogen in the severe and fatal cases (n=22, 78.6%). Phylogenetic analysis of VP1 gene sequences showed the EV-71 isolates to belong to subgenotype C4a, and the CV-A16 isolates to belong to subgenotype B1. The Changsha CV-A6 and CV-A10 circulating strains were homologous to strains circulating in other areas of mainland China. Our results demonstrate that EV-71 was the primary causative agent responsible for the HFMD outbreak in Changsha in 2012, and the co-circulation of other coxsackievirus A strains posed a potential risk to public health.

    Yuan Xu

    Full Text Available A new species of Primulaceae, Primula undulifolia, is described from the hilly area of Hunan province in south-central China. Its morphology and distributional range suggest that it is allied to P. kwangtungensis, both adapted to subtropical climate, having contiguous distribution and similar habitat, growing on shady and moist cliffs. Petioles, scapes and pedicels of them are densely covered with rusty multicellular hairs, but the new species can be easily distinguished by its smaller flowers and narrowly oblong leaves with undulate margins. Molecular phylogenetic analysis based on four DNA markers (ITS, matK, trnL-F and rps16 confirmed the new species as an independent lineage and constitutes a main clade together with P. kwangtungensis, P. kweichouensis, P. wangii and P. hunanensis of Primula sect.

    Depressive symptoms are common among people living with HIV (PLWH) and are associated with poor adherence to antiretroviral treatment and poor treatment outcomes. Our study investigated the prevalence of and factors associated with depressive symptoms in PLWH in one Chinese province. Data were collected from 496 PLWH between July 2009 and July 2010 at two HIV treatment sites in Hunan Province, China. Sixty-two percent (n = 309) of participants scored 16 or more on the Center for Epidemiological Studies of Depression scale, indicating moderate to high levels of depressive symptoms. Independent predictors of depressive symptoms included active heroin use, lack of a stable job, female gender, and limited social support. These data suggest that interventions addressing depressive symptoms should be included in HIV care programs provided by the Chinese government, with a special focus on PLWH who are heroin users, female, unemployed, or socially isolated.

    Aquatic products are important sources of animal proteins in human diet, especially in developing countries. As such, the safety of aquatic products is of primary concern. In this study, a standard method is used to detect malachite green (MG) and chloramphenicol (CAP) and to analyse the contents of these banned chemicals in turtle, mandarin fish and grass carp sampled from the region surrounding Dongting Lake area in Hunan, China. Results showed that 10.6% of the samples were MG-positive, most of them turtles. CAP was found in 8.3% of the samples, mostly in mandarin fish. These data indicated that these banned substances are still used in the surveyed area. Hence, adequate strategies must be implemented by the local government to control these banned substances.

  19. Protest Leadership and Repertoire: A Comparative Analysis of Peasant Protest in Hunan in the 1990s

    2013-01-01

    Full Text Available Based on detailed ethnographic fieldwork, this paper compares two cases of peasant protest against heavy taxes and fees in a northern Hunan county in the 1990s. It argues that peasant protest did not arise spontaneously. Rather, it erupted when leaders emerged who used central policy documents on lowering peasant taxes and fees to mobilise peasants. Protest leaders were articulate and public-spirited peasants who had received political training from the local party-state. Furthermore, the number of leaders, their education level, and their relationship with the local party-state explain why the repertoire and the scope of the two protests varied. Protests led by less educated veteran Communist Party cadres tended to be milder and smaller than those led by better-educated peasants more distant from the local party-state. This paper helps us to understand the process of peasant mobilisation in contemporary China and explains why peasant protest varies across cases.

    Full Text Available Background: With the development of economy and urbanization, methods of child-feeding have significantly changed in China over the past three decades. However, little is known about breastfeeding in China since 2009. This study aims to update information on the prevalence of breastfeeding in China. Methods: Data were obtained from the first Health Service Household Interview Survey of Hunan Province, China. Of 24,282 respondents, 1659 were aged five years or younger. We ran multivariable logistic regression to examine the impact of urban/rural setting, gender, age and household income per capita on the use of breastfeeding. Results: A total of 79.4% of children aged 5 years or younger had been breastfed at some point and 44.9% been breastfed exclusively in the first 6 months of life. After controlling for setting urban/rural setting, gender and child age, children from households with average family income were more likely to be breastfed than those from households with the lowest family income (adjusted odds ratio: 2.28. Children from households with higher and the highest family income were less likely to be exclusively breastfed in the first 6 months of life compared to those from households with the lowest family income (adjusted odds ratio: 0.51 and 0.68, respectively. Conclusions: It is encouraging that the prevalence of exclusive breastfeeding for infants in the first 6 months of life in Hunan Province, China is approaching the goal of 50% proposed by the World Health Organization (WHO. Nevertheless, more efforts are needed to further promote exclusive breastfeeding in the first 6 months after birth.

    Full Text Available Based on regional coordination theory and system theory, the authors constructed an evaluation index system for the coordinated development of a regional environment-tourism-economy system with a pressure-state-response (PSR model. With a coordinated development model, it further empirically analyzed the coordinated development state of an environment-tourism-economy system in western Hunan from 2001 to 2012. The results showed that, although this environment-tourism-economy system failed to achieve a high benefit index, inter-subsystem coupling extent, and coordinated development index, the three indices presented an increasing overall trend. This outcome suggested that the sub-systems in this system were developing towards their optimal proportions: the development of these sub-systems (environmental, tourism, and economic was unbalanced in western Hunan. The environment therein sees only slow development although provided with a favorable ecological foundation. Economic development, which has long been lagging, acted as the main factor restricting the coordinated development of a regional environment-tourism-economy system. To promote its coordinated development in western Hunan, the following recommendations were proposed: strengthen the prediction and warnings on the evolution of the whole system; optimize the industry’s structure; reinforce environmental management.

    Taking a large standard runoff plot on a red soil slope in Qiyang County, southern Hunan Province as a case, this paper studied the surface soil phosphorus loss characteristics in the hilly red soil regions of southern Hunan under eight ecological planting patterns. The phosphorus loss from wasteland (T1) was most serious, followed by that from natural sloped cropping patterns (T2 and T3), while the phosphorus loss amount from terrace cropping patterns (T4-T8) was the least, only occupying 9.9%, 37%, 0.7%, 2.3%, and 1.9% of T1, respectively. The ecological planting patterns directly affected the forms of surface-lost soil phosphorus, with the particulate phosphorus (PP) as the main lost form. Under the condition of rainstorm (daily rainfall > 50 mm), rainfall had lesser effects on the phosphorus loss among different planting patterns. However, the phosphorus loss increased with increasing rain intensity. The surface soil phosphorus loss mainly occurred from June to September. Both the rainfall and the rain intensity were the factors directly affected the time distribution of surface soil phosphorus loss in hilly red soil regions of southern Hunan.

    Full Text Available Farmland abandonment, including perennial and seasonal abandonment, is an important process of land use change that matters most to food security. Although there is a great deal of studies on farmland abandonment, seasonal abandonment, which is as serious as perennial abandonment, has attracted little academic attention. This paper takes Hunan Province in central China as its study area and uses a spatial regression model to examine the driving factors of seasonal farmland abandonment at the county level. Our results show that farmland abandonment has striking spatial relativity, and there are two clustering zones with a high index of farmland abandonment (IFA in the Dongting plain and the basin in south-central Hunan, while a clustering zone of low IFA can be found in the mountains of southwest Hunan. Farmland abandonment at the regional level is negatively affected by the land productive potentialities, proportion of mechanized planting, ratio of effective irrigation, and distance to provincial capital, while it is positively associated with the variables mountainous terrain, per capita farmland area, and labor shortage. Additionally, farmland abandonment is also affected by adjacent areas through its spatial dependence. In short, seasonal farmland abandonment is also driven integratedly by the socioeconomic and environmental dimensions and spatial interaction of farm abandonment.

    To summarize the molecular epidemiology of hemoglobinopathies in Yongzhou area of Hunan province in order to provide a basis for making the guidelines of local thalassemia prevention program. Two thousand and two samples (1001 couples) were randomly recruited based on demographic data and distribution of ethnic groups. All samples were subjected to full blood count and analysis of hemoglobin and 6 common alpha-thalassemia mutations. Known beta-thalassemia mutations were screened in samples with beta-thalassemia trait. The remaining samples with positive phenotype and unknown mutations were subjected to DNA sequence analysis. Two hundred and forty individuals were found to be carriers of hemoglobinopathic mutations, which included 6 common alpha-thalassemia deletions, 9 common beta-thalassemia mutations and 3 common structural hemoglobin variants. One hundred and seventy-four mutant alleles for alpha-thalassemia were detected, which gave a carrier rate of 8.69%, of which 0.1% was due to HbH disease. Seventy mutant alleles for beta-thalassemia were detected, which gave a carrier rate of 3.50%. Seven subjects (0.35%) were identified as carriers of hemoglobin variants. The overall carrier rate for hemoglobinopathic mutations was 12.54% based on detection of 251 hemoglobinopathy mutant alleles. The overall carrier rate for alpha- and beta-thalassemia among ethnic Yaos was 25.00%, which was significantly higher than that of ethnic Han Chinese (11.14%, Phemoglobinopathies in Yongzhou area has been delineated for the first time.

    Comparative embryology is integral to uncovering the pattern and process of metazoan phylogeny, but it relies on the assumption that life histories of living taxa are representative of their antecedents. Fossil embryos provide a crucial test of this assumption and, potentially, insight into the evolution of development, but because discoveries so far lack phylogenetic constraint, their significance is moot. Here we describe a collection of embryos from the Middle and Late Cambrian period (500 million years ago) of Hunan, south China, that preserves stages of development from cleavage to the pre-hatching embryo of a direct-developing animal comparable to living Scalidophora (phyla Priapulida, Kinorhyncha, Loricifera). The latest-stage embryos show affinity to the Lower Cambrian embryo Markuelia, whose life-history strategy contrasts both with the primitive condition inferred for metazoan phyla and with many proposed hypotheses of affinity, all of which prescribe indirect development. Phylogenetic tests based on these embryological data suggest a stem Scalidophora affinity. These discoveries corroborate, rather than contradict, the predictions of comparative embryology, providing direct historical support for the view that the life-history strategies of living taxa are representative of their stem lineages.

    Full Text Available Bacillary dysentery remains a public health concern in the world. Hunan Province is one of the provinces having the highest risk of bacillary dysentery in China, however, the spatial-temporal distribution, variation of bacillary dysentery and sensitivity to meteorological factors in there are unclear. In this paper, a Bayesian space-time hierarchical model (BSTHM was used to detect space-time variation, and effects of meteorological factors between 2010 and 2015. The risk of bacillary dysentery showed apparent spatial-temporal heterogeneity. The highest risk occurred in the summer season. Economically undeveloped mountainous areas in the west and south of the province had the highest incidence rates. Twenty three (18.9% and 20 (16.4% counties were identified as hot and cold spots, respectively. Among the hotspots, 11 counties (47.8% exhibited a rapidly decreasing trend, suggesting they may become low-risk areas in the future. Of the cold spot counties, six (30% showed a slowly decreasing trend, and may have a higher risk in the future. Among meteorological factors, air temperature, relative humidity, and wind speed all played a significant role in the spatial-temporal distribution of bacillary dysentery risk. These findings can contribute to the implementation of an early warning system for controlling and preventing bacillary dysentery.

    Homelessness is an increasingly important problem for individuals with serious mental illness in China. Identify the characteristics of families that are associated with homelessness among individuals with schizophrenia. Participants were 1856 homeless individuals with schizophrenia (defined as those who had no place of residence or involved caregivers for 7 consecutive days) and 1728 non-homeless individuals with schizophrenia from Xiangtan, Hunan. The self-completion Family Environment Scale-Chinese Version (FES-CV) was administered to these participants after their acute psychotic symptoms resolved. Compared to individuals in the non-homeless group, those in the homeless group were older and more likely to be non-locals (i.e., from outside of Xiangtan), be residents of rural (versus urban) communities, have temporary (versus permanent) jobs, be married, and have a low level of education. After controlling for demographic differences using multivariate logistic regression models, homelessness was independently associated higher scores in the FES-CV intellectual-cultural orientation, organization, achievement orientation, and control subscales and with lower scores in the FES-CV cohesion, moralreligious emphasis, independence, and active-recreational orientation subscales. After controlling for sociodemographic factors, certain aspects of the family environment areassociated with being homeless among patients with schizophrenia in China. Further work is needed to identify interventions that can reduce the risk of homelessness in high-risk individuals.

    To explore the relationship between posttraumatic stress disorder (PTSD) in flood victim parents and children in Hunan, China. Using the method of multistage cluster random sampling, we conducted a retrospective investigation on 3,698 families in Hunan, China who suffered from flooding in 1998. Investigators held face-to-face interviews with the parents and children of the families. The diagnosis of PTSD was made according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. The comparison of rate of PTSD positive in the groups of children with different characteristics was done by chi-square test. In the evaluation of the impact of parent PTSD on PTSD in their children, we used a multivariable logistic regression model to re-estimate the adjusted Odds Ratio and its confidence interval. We did this after the possible confounding variables were adjusted for. Additionally, the Odds Ratio and its confidence interval were estimated under the condition of a single variable. A total of 4,327 children and the parents of 3,292 families were included for analysis; 203 (4.7%) of 4,327 children and 740 (11.2%) of 6,584 parents were diagnosed with PTSD. We found that the PTSD positive rate is significantly higher in the children with disaster-related experience. The rate of beating their children in PTSD positive fathers (54.9%) was higher than that of PTSD negative fathers (51.2%). No correlation was found between mothers' PTSD and beating their children. The risk of developing PTSD is higher for children living in the families with PTSD parents. The rate of PTSD in 7-14-year-old children is 4.7% in areas in Hunan, China, who suffered from flooding in 1998. The possibility for children to develop PTSD is increased in families with PTSD parents.

    Rocky desertification is a major ecological problem of land degradation in karst areas. In these areas, the high soil calcium (Ca) content has become an important environmental factor that can affect the restoration of vegetation. Consequently, the screening of plant species that can adapt to high Ca soil environments is a critical step in vegetation restoration. In this study, three grades of rocky desertification sample areas were selected in karst areas of southwestern Hunan, China (LRD: light rocky desertification; MRD: moderate rocky desertification; and IRD: intense rocky desertification). Each grade of these sample areas had three sample plots in different slope positions, each of which had four small quadrats (one in rocky-side areas, three in non-rocky-side areas). We measured the Ca content of leaves, branches, and roots from 41 plant species, as well as soil total Ca (TCa) and exchangeable Ca (ECa) at depths of 0-15, 15-30, and 30-45 cm in each small quadrat. The results showed that the soil Ca2+ content in rocky-side areas was significantly higher than that in non-rocky-side areas (p desertification, in the order IRD > MRD > LRD. For all plant functional groups, the plant Ca content of aboveground parts was significantly higher than that of the belowground parts (p 1). The differences in Ca2+ content between the aboveground and belowground parts of the 17 dominant species were calculated, and their correlations with soil ECa content were analyzed. The results showed that these 17 species can be divided into three categories: Ca-indifferent plants, high-Ca plants, and low-Ca plants. These findings provide a vital theoretical basis and practical guide for vegetation restoration and ecosystem reconstruction in rocky desertification areas.

    Paddy rice has been likened to nictiana sp in its ability to scavenge cadmium (Cd) from soil, whereas arsenic (As) accumulation is commonly an order of magnitude higher than in other cereal crops. In areas such as those found in parts of Hunan province in south central China, base-metal mining activities and rice farming coexist. Therefore there is a considerable likelihood that lead (Pb), in addition to Cd and As, will accumulate in rice grown in parts of this region above levels suitable for human consumption. To test this hypothesis, a widespread provincial survey of rice from mine spoilt paddies (n = 100), in addition to a follow-up market grain survey (n = 122) conducted in mine impacted areas was undertaken to determine the safety of local rice supply networks. Furthermore, a specific Cd, As, and Pb biogeochemical survey of paddy soil and rice was conducted within southern China, targeting sites impacted by mining of varying intensities to calibrate rice metal(loid) transfer models and transfer factors that can be used to predict tissue loading. Results revealed a number of highly significant correlations between shoot, husk, bran, and endosperm rice tissue fractions and that rice from mining areas was enriched in Cd, As, and Pb. Sixty-five, 50, and 34% of all the mine-impacted field rice was predicted to fail national food standards for Cd, As, and Pb, respectively. Although, not as elevated as the grains from the mine-impacted field survey, it was demonstrated that metal(loid) tainted rice was entering food supply chains intended for direct human consumption.

    We aimed to investigate whether the cadmium concentrations differ in human dental calculus obtained from the residents with no smoking living in the contaminated area and those with no smoking living in noncontaminated area. In total, there were 260 samples of dental calculus from the adults (n = 50) with no smoking living in contaminated area, the adults (n = 60) with no smoking living in mountainous area, and the adults (n = 150) with no smoking living in low altitude area in Hunan province of China. All samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) for cadmium levels. The cadmium levels in dental calculus were significantly higher in the adults with no smoking living in contaminated area than those living in mountainous area and in low altitude area (p dental calculus were also higher in the adults with no smoking living in low altitude area than those living in mountainous region (p dental calculus may be a useful noninvasive method for analysis of environmental exposure to cadmium in the human oral cavity. The low altitude region may have an area contaminated with cadmium in Hunan province of China.

    Huangshaping polymetallic deposit, located in southern Hunan Province, China, hosts abundant W-Mo-Pb-Zn mineralization which linked with the skarn system located between late Mesozoic high-K calc-alkaline to shoshonitic granitoids and the Carboniferous carbonate in this deposit. In this study, concentrations of trace and minor elements of the magnetites from different skarn stages are obtained by in situ LA-ICP-MS analysis, in order to further understand the polymetallic mineralization processes within this deposit. The generally high concentrations of spinel elements, including Mg, Al, Ti, Mn, V, Cr, Co, Ni, Ga, Ge, and Sn, in all magnetites from this deposit suggest that these elements are incorporated into magnetite lattice by substituting Fe3+ and/or Fe2+. However, the various concentrations of Na, Si, K, Ca, and W elements in magnetites, combining the abnormal time-resolved analytical signals of LA-ICP-MS analyses, suggest that these elements are significantly affected by the fluid inclusions in magnetites. Two groups of magnetites can be further distinguished based on their trace and minor elements concentrations: Group-1 magnetites, including those in medium grain garnets and calcite, have obvious lower Na, Si, K, Ca, Sn, W, but higher Mg, Al, Ti, V, Co, Ni, Zn concentrations compared with Group-2 magnetites, which including those in coarse grain garnets, tremolite, and bulk magnetite ores. This suggests that the hydrothermal fluids where Group-2 magnetites precipitated are evolved magmatic fluids which have undergone the crystal fractionation during the early skarn stages (eg. Garnet and tremolite), the high Na, Si, K, and Ca in the hydrothermal fluids probably result from the dissolution of the host rocks, such as limestone, sandstone, and evaporite horizons in this deposit. However, the Group-1 magnetites probably precipitated in the hydrothermal fluids with low salinity, which result the low Na, Si, K, and Ca in these magnitites. Furthermore, these

    Full Text Available Rocky desertification is a major ecological problem of land degradation in karst areas. In these areas, the high soil calcium (Ca content has become an important environmental factor that can affect the restoration of vegetation. Consequently, the screening of plant species that can adapt to high Ca soil environments is a critical step in vegetation restoration. In this study, three grades of rocky desertification sample areas were selected in karst areas of southwestern Hunan, China (LRD: light rocky desertification; MRD: moderate rocky desertification; and IRD: intense rocky desertification. Each grade of these sample areas had three sample plots in different slope positions, each of which had four small quadrats (one in rocky-side areas, three in non-rocky-side areas. We measured the Ca content of leaves, branches, and roots from 41 plant species, as well as soil total Ca (TCa and exchangeable Ca (ECa at depths of 0–15, 15–30, and 30–45 cm in each small quadrat. The results showed that the soil Ca2+ content in rocky-side areas was significantly higher than that in non-rocky-side areas (p < 0.05. The mean soil TCa and ECa content increased gradually along with the grade of rocky desertification, in the order IRD > MRD > LRD. For all plant functional groups, the plant Ca content of aboveground parts was significantly higher than that of the belowground parts (p < 0.05. The soil ECa content had significant effects on plant Ca content of the belowground parts but had no significant effects on plant Ca content of the aboveground parts. Of the 41 plant species that were sampled, 17 were found to be dominant (important value > 1. The differences in Ca2+ content between the aboveground and belowground parts of the 17 dominant species were calculated, and their correlations with soil ECa content were analyzed. The results showed that these 17 species can be divided into three categories: Ca-indifferent plants, high

    Located in Central South China, Hunan province is rich in mineral resources. To study the influence of mining on Cd pollution to local agricultural eco-system, the paddy soils and rice grain of Y county in northern Hunan province were intensively monitored. The results were as follows: (1) Total Cd (T-Cd) content in the soils of the county ranges from 0.13 to 6.02 mg kg(-1), with a mean of 0.64 mg kg(-1), of which 57.5% exceed the allowable limit specified by the China Soil Environmental Quality Standards. T-Cd in the soils varies largely, with the coefficient of variation reaching 146.4%. The spatial distribution of T-Cd in the soils quite matches with that of mining and industries. The content of HCl-extractable Cd (HCl-Cd) in the soils ranges from 0.02 to 2.17 mg kg(-1), with a mean of 0.24 mg kg(-1). A significant positive correlation exists between T-Cd and HCl-Cd in the soils (r = 0.770, ρ soils (r = 0.091, ρ > 0.05), which suggests that the amount of Cd accumulating in the rice is more affected by its availability in the soils, rather than the total content. (4) The dietary intake of Cd via rice consumption in Y county is estimated to be 179.9 μg day(-1) person(-1) on average, which is far beyond the allowable limit specified by FAO/WHO and the target hazard quotients of Cd much higher than 1, suggesting the high risk on human health from Cd exposure.

    Understanding the potential links between floods and infectious diarrhea is important under the context of climate change. However, little is known about the risk of infectious diarrhea after floods and what factors could modify these effects in China. This study aims to quantitatively examine the relationship between floods and infectious diarrhea and their effect modifiers. Weekly number of infectious diarrhea cases from 2004 to 2011 during flood season in Hunan province were supplied by the National Notifiable Disease Surveillance System. Flood and meteorological data over the same period were obtained. A two-stage model was used to estimate a provincial average association and their effect modifiers between floods and infectious diarrhea, accounting for other confounders. A total of 134,571 cases of infectious diarrhea were notified from 2004 to 2011. After controlling for seasonality, long-term trends, and meteorological factors, floods were significantly associated with infectious diarrhea in the provincial level with a cumulative RR of 1.22 (95% CI: 1.05, 1.43) with a lagged effect of 0-1 week. Geographic locations and economic levels were identified as effect modifiers, with a higher impact of floods on infectious diarrhea in the western and regions with a low economic level of Hunan. Our study provides strong evidence of a positive association between floods and infectious diarrhea in the study area. Local control strategies for public health should be taken in time to prevent and reduce the risk of infectious diarrhea after floods, especially for the vulnerable regions identified.

    In this study, the trends and periodicity in climate extremes are examined in Hunan Province over the period 1960-2013 on the basis of 27 extreme climate indices calculated from daily temperature and precipitation records at 89 meteorological stations. The results show that in the whole province, temperature extremes exhibit a warming trend with more than 50% stations being statistically significant for 7 out of 16 temperature indices, and the nighttime temperature increases faster than the daytime temperature at the annual scale. The changes in most extreme temperature indices show strongly coherent spatial patterns. Moreover, the change rates of almost all temperature indices in north Hunan are greater than those of other regions. However, the statistically significant changes in indices of extreme precipitation are observed at fewer stations than in extreme temperature indices, forming less spatially coherent patterns. Positive trends in indices of extreme precipitation show that the amount and intensity of extreme precipitation events are generally increasing in both annual and seasonal scales, whereas the significant downward trend in consecutive wet days indicates that the precipitation becomes more even over the study period. Analysis of changes in probability distributions of extreme indices for 1960-1986 and 1987-2013 also demonstrates a remarkable shift toward warmer condition and increasing tendency in the amount and intensity of extreme precipitation during the past decades. The variations in extreme climate indices exhibit inconstant frequencies in the wavelet power spectrum. Among the 16 temperature indices, 2 of them show significant 1-year periodic oscillation and 7 of them exhibit significant 4-year cycle during some certain periods. However, significant periodic oscillations can be found in all of the precipitation indices. Wet-day precipitation and three absolute precipitation indices show significant 1-year cycle and other seven provide

    The study area is among Changsha, Zhuzhou, and Xiangtan cities, which was under agricultural use and natural conditions about 10 years ago and now is becoming part of the metropolis because of the urban expansion. This study aims to investigate the mechanisms and capabilities of the local alluvial soil layer for protecting the local shallow groundwater from arsenic pollution by field surveys and batch experiments. The field surveys showed that there was an acidic tendency of the groundwater, and phosphate, nitrate, and arsenic in the groundwater significantly increased comparing to their reference values. It indicates that the disturbance of the former agricultural land due to the change of land use may be responsible for these changes. From the experimental results, the maximum adsorption capacity of the soil for As(V) was as low as 0.334 mg/g, and lower As(V) adsorption capacities were obtained at higher As(V) concentration, higher pH, and lower temperature. The presence of H 2 PO 4 - and SiO 3 2- posed negative, while HCO 3 - slight positive, and SO 4 2- , NO 3 - and Cl - negligible influences on the As(V) adsorption. The surface-derived organic matter played a negative role in the adsorption process, and low specific surface area influenced adsorption capacity of the soil. The study reveals that the local soil layer shows poor potential for protection of the local shallow groundwater from As(V) pollution, and the change trends of the groundwater environments due to more intensive anthropogenic activities will further weaken this potential and increase the risk of the groundwater contamination.

    Important to the evolution of Danxia landforms is how the rock cliffs are in large part shaped by rock collapse events, ranging from small break offs to large collapses. Quantitative research of Danxia landform evolution is still relatively young. In 2013-2014, Chinese and Slovak researchers conducted joint research to measure deformation of two large rock walls. In situ measurements of one rock wall found it to be stable, and Ps-InSAR measurements of the other were too few to be validated. Research conducted this year by Chinese researchers modeled the stress states of a stone pillar at Mt. Langshan, in Hunan Province, that toppled over in 2009. The model was able to demonstrate how stress states within the pillar changed as the soft basal layer retreated, but was not able to show the stress states at the point of complete collapse. According to field observations, the back side of the pillar fell away from the entire cliff mass before the complete collapse, and no models have been able to demonstrate the mechanisms behind this behavior. A further understanding of the mechanisms controlling rockfall events in Danxia landforms is extremely important because these stunning sceneries draw millions of tourists each year. Protecting the tourists and the infrastructure constructed to accommodate tourism is of utmost concern. This research will employ a UAV to as universally as possible photograph a stone pillar at Mt. Langshan that stands next to where the stone pillar collapsed in 2009. Using the recently developed structure-from-motion technique, a 3D model of the pillar will be constructed in order to extract geometrical data of the entire slope and its structural fabric. Also in situ measurements will be taken of the slope's toe during the field work exercises. These data are essential to constructing a realistic discrete element model using the 3DEC code and perform a kinematic analysis of the rock mass. Intact rock behavior will be based on the Mohr Coulomb

    Xiangxi flavor vinegar (XV) is one of Hunan Province’s traditional fermented vinegars. It is produced from herb, rice, and spring water with spontaneous liquid-state fermentation techniques. In this study, we investigated the antioxidant property of XV by analyzing its antioxidant compounds, its free radical scavenging property in vitro and in vivo, and its effects on antioxidant enzyme activity and apoptosis in Caenorhabditis elegans. The results showed that XV is rich in antioxidants. In particular, ligustrazine reached 6.431 μg/ml. The in vitro 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH•), hydroxyl radical (•OH), and superoxide anion radical (O2 •−) scavenging rates of XV were 95.85%, 97.22%, and 63.33%, respectively. The reactive oxygen species (ROS) content in XV-treated C. elegans decreased significantly (P<0.01) compared to the control group. Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities were remarkably increased (P<0.01) in C. elegans after XV treatment. In addition, XV could upregulate CED-9 protein expression and downregulate CED-3 protein expression in C. elegans. These results prove that XV is rich in antioxidants and scavenges radicals in vitro efficiently. XV inhibits apoptosis in C. elegans probably by scavenging ROS and increasing the activities of its antioxidant enzymes. PMID:28378570

    To clarify the role of socio-economy and management in the sustainable schistosomiasis-control in Taoyuan County, an endemic area in hilly region, Hunan Province, China. From 1996 to 2011, the data of socio-economy, the management of schistosomiasis control organizations, environment, and the changes in schistosomiasis prevalence were collected in Taoyuan County where schistosomiasis transmission had been controlled since 2008. A sampling survey of schistosomiasis prevalence of human and bovine was performed in 2011 to verify the current status of schistosomiasis transmission. All the data were analyzed statistically to evaluate the role of socio-economy and management in the sustainable schistosomiasis control. During the period from 1998 to 2012, the socio-economy including the residents' productive mode and daily life in Taoyuan County improved dramatically, but the recurrence risk of schistosomiasis endemic still existed due to the retuning of out-going workers and the migrating population. Moreover, the introduction of exotic species of plants and animals may increase the risk. The low running cost of schistosomiasis control organization as well as the efficient and adequate resource allocation in the county was in line with the national requirement to strengthen the rural grass-roots public health system. The harmonious development of socio-economy and the scientific and efficient health system in Taoyuan County are the key factors for the sustainable transmission control of schistosomiasis.

    Full Text Available Children in contemporary rural China have experienced an unprecedented moment; amid radical economic and social transformations that have sent their parents to urban centers to earn cash income, children have been left behind to live with older relatives. This fundamental redefining of place, parenting, and living has rarely been written about by the children themselves in English. Set in rural Hunan in the late twentieth and early twenty-first centuries, this novel vividly describes farm production, the shift from an agricultural way of life to a life financially supported by migrant labor earnings, local religious life, Huagu opera, education, complex and violent relationships between family members and villagers, the deaths of the protagonist's (Maomao mother and paternal grandmother, a wedding, funerals, and local festivals – from the perspective of a child. Refusing to drop out of school and become a migrant worker or a soldier, Maomao eventually achieves his dream of becoming a university student against all odds. This unvarnished and vividly written description of a contemporary rural life in China is uniquely important and appealing to a broad readership.

    A region-wide sampling survey was conducted in 1995 in order to evaluate the current epidemiological status of schistosomiasis japonica in Hunan Province, China. A total of 45,590 humans and 3,726 domestic animals, from 52 villages, were examined parasitologically and/or serologically for current Schistosoma japonicum infections. In uncontrolled endemic areas (43 villages) the overall human prevalence of S. japonicum was 7.81% across the different geographical subtypes. The geometric mean intensity of infection was 17.71 eggs per gram (epg) among infected individuals and only 1.25 epg in the general population. The bovine prevalence, as determined by the hatching test, was 9.63% in the uncontrolled endemic villages. Only one sero-positive (by indirect hemagglutination assay) child was found among 1,072 children tested aged 10-14 years in the 9 endemic villages under effective control. No infection was confirmed by the Kato-Katz thick smear stool examination. When the results of this survey were compared to those seen at baseline (1989) an overall reduction of 45.65% was seen in the human prevalence but no significant change was apparent in the lake-beach ecotype. Additionally, there was more than a 60% reduction in the prevalence among bovines over the same sampling period. The results demonstrate that the World Bank Loan Schistosomiasis Program was successful in achieving its most basic objectives for this province - to reduce human and bovine infections by 40%.

    We have investigated the interactions between economic growth and industrial wastewater discharge from 1978 to 2007 in China's Hunan Province using co-integration theory and an error-correction model. Two main economic growth indicators and four representative industrial wastewater pollutants were selected to demonstrate the interaction mechanism. We found a long-term equilibrium relationship between economic growth and the discharge of industrial pollutants in wastewater between 1978 and 2007 in Hunan Province. The error-correction mechanism prevented the variable expansion for long-term relationship at quantity and scale, and the size of the error-correction parameters reflected short-term adjustments that deviate from the long-term equilibrium. When economic growth changes within a short term, the discharge of pollutants will constrain growth because the values of the parameters in the short-term equation are smaller than those in the long-term co-integrated regression equation, indicating that a remarkable long-term influence of economic growth on the discharge of industrial wastewater pollutants and that increasing pollutant discharge constrained economic growth. Economic growth is the main driving factor that affects the discharge of industrial wastewater pollutants in Hunan Province. On the other hand, the discharge constrains economic growth by producing external pressure on growth, although this feedback mechanism has a lag effect. Economic growth plays an important role in explaining the predicted decomposition of the variance in the discharge of industrial wastewater pollutants, but this discharge contributes less to predictions of the variations in economic growth.

    Full Text Available Severe mental illness (SMI represents major social and public health problem in China, especially in low- or middle-income regions. We aim to assess the prevalence and distribution of SMI in Hunan province in central China.Multistage stratified random sampling methods were used to select qualified subjects in 123 districts and counties in Hunan province. 89465 individuals were randomly identified, and 72999 (81.6% completed the supplemental 12-Item General Health Questionnaire (GHQ-12 and Cue questionnaire of psychiatric abnormal behaviors. 6082 suspected individuals having high or moderate risk, or psychiatric cues, were administered the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I by psychiatrists.720 respondents were definitely diagnosed as SMI. The 1-month and lifetime prevalence was 9.35‰ and 10.10‰, respectively. The most frequent SMI was schizophrenia, followed by bipolar disorder, intellectual disability, epileptic mental disorder, paranoid psychosis and schizoaffective disorders, with 1-month prevalence ranging from 0.11‰ to 6.50‰ and lifetime prevalence ranging from 0.24‰ to 6.86‰. Multivariate logistic regression analysis revealed that lower education, farmer occupation, retirees or jobless/unemployed, unmarried or divorced and age of 30-64 years old were major factors that associated with the increased risk of SMI. In addition, only 33.3% of 528 patients who completed questionnaire sought help in psychiatric institutions, and up to 51.7% of 720 patients were not referred to the SMI management system in Hunan province.These findings provided a large-scale prevalence data of SMI in a provincial sample of China. The psychiatric disorders brought economical and psychological burden for family and society, which may shed light on the significance of scaling up province-wide mental health service and strengthening the SMI management.

    To investigate ORMDL3 polymorphisms in children with asthma in Hunan, China, and to determine the relationship between ORMDL3 polymorphisms and serum osteopontin (OPN) and transforming growth factor-β1 (TGF-β1) levels. Peripheral blood samples were collected in children with asthma (n=98; astma group) or without asthma (n=30; control group) from Hunan, China. The asthma group was subdivided into atopic (n=62) and non-atopic (n=36) subgroups. Single nucleotide polymorphism (SNP) analysis was performed, and serum OPN and TGF-β1 levels were measured. There were no significant differences in genotype and allele frequencies of rs7216389 of the ORMDL3 gene between the asthma and control groups. The serum level of OPN in the asthma group was significantly higher than in the control group (P<0.05). Both the atopic and non-atopic subgroups showed increased serum levels of OPN compared with the control group (P<0.05). The serum level of TGF-β1 in the atopic subgroup was significantly higher than in the control group (P<0.05). The serum levels of OPN and TGF-β1 showed no significant differences in asthmatic children with different genotypes. The serum levels of OPN and TGF-β1 were in a positive linear correlation in the asthma group (r=0.620; P<0.01) and its two subgroups (r=0.734, 0.649 respectively; P<0.01). In children from Hunan, China, the SNP (rs7216389) of ORMDL3 is not related to asthma susceptibility. OPN and TGF-β1 may be involved in the development of asthma, and they are in a positive linear correlation. The SNP (rs7216389) of ORMDL3 does not influence the expression of OPN and TGF-β1, suggesting that it may not be associated with airway remodeling.

    Hunan province, Central South China, is a well-known nonferrous metal base in China. Mine exploiting and processing there, however, often lead to heavy metal pollution of farmland. To study the effects of mining activities on the soil environmental quality, four representative paddy fields, the HSG, SNJ, NT and THJ, in Y county, northern Hunan province, were investigated. It was found that the streams running through the HSG, SNJ and NT are severely contaminated due to the long-term discharge of untreated mineral wastewater from local indigenous mining factories. The stream at the HSG, for example, is brownish red in color, with high concentrations of Cu, Zn, Cd, Fe and Mn. The concentrations of Cu, Zn and Cd in all the stream water of the HSG, SNJ and NT exceed the maximum allowable levels of the Agricultural Irrigation Water Criteria of China. Correspondingly, the HSG, SNJ and NT are heavily polluted by Cu, Zn and Cd due to the long-term irrigation with the contaminated stream water. In comparison, both stream water and paddy fields of the THJ, far away from mining areas, are not contaminated by any heavy metals and hence regarded as a control in this study. The rice grain produced at the HSG, SNJ and NT has a high risk of Cd contamination. The rate of rice grain produced in the four paddy fields in Y county with Cd exceeding the safe level (Cd, 0.2 μg g-1) specified by the National Standards for Rice Quality and Safety of China reaches 90%. Cd content in the rice grain is positively significantly correlated with that in the paddy fields, especially with the content of diethylenetriaminepentaacetic acid (DTPA) - extracted Cd, suggesting that the heavy metal pollution of paddy fields has already posed a high risk to rice safety and human health. Soil enzyme activities and microbial biomass are significantly inhibited by the heavy metal pollution of the paddy fields. Microbial biomass C and N (MBC and MBN) at a severely contaminated site of the HSG are only 31

    Soil pollution by Cd, Hg, As, Pb, Cr, Cu, and Zn was characterized in the area of the mining and smelting of metal ores at Guiyang, northeast of Hunan Province. A total of 150 topsoil (0-20 cm) samples were collected in May 2012 with a nominal density of one sample per 4 km(2). High concentrations of heavy metals especially, Cd, Zn, and Pb were found in many of the samples taken from surrounding paddy soil, indicating a certain extent of spreading of heavy metal pollution. Sequential extraction technique and risk assessment code (RAC) were used to study the mobility of chemical forms of heavy metals in the soils and their ecological risk. The results reveal that Cd represents a high ecological risk due to its highest percentage of the exchangeable and carbonate fractions. The metals of Zn and Cu pose a medium risk, and the rest of the metals represent a low environmental risk. The range of the potential ecological risk of soil calculated by risk index (RI) was 123.5~2791.2 and revealed a considerable-high ecological risk in study area especially in the neighboring and surrounding the mining activities area. Additionally, cluster analyses suggested that metals such as Pb, As, Hg, Zn, and Cd could be from the same sources probably related to the acidic drainage and wind transport of dust. Cluster analysis also clearly distinguishes the samples with similar characteristics according to their spatial distribution. The results could be used during the ecological risk screening stage, in conjunction with total concentrations and metal fractionation values to better estimate ecological risk.

    To investigate the situation regarding the cleaning and sterilization of endonasal endoscopes in department of otolaryngology in Hunan Province, and to provide strategy for improving the level of sterilization and management of endonasal endoscopes.
 A total of 100 medical institutions were investigated by spot assessment, check and sampling. Data was analyzed by multivariate analysis.
 The qualified rate of rules and regulations for endoscopy was 28.8% in the second-class hospitals and 45% in the top-class hospitals. The qualified rate of environment for endoscopy cleaning and sterilization was 36.3% in the second-class hospitals and 85% in the top-class hospitals. The main problems include lack of independent disinfection room, the space not large enough, and/or lack of ventilation system. The qualified rate of bacterial detection for post-sterilized endoscopes and biopsy forceps was 93.8% in the second-class hospitals and 95.0% in the top-class hospitals, and the main pathogenic bacteria was gram-positive cocci and gram-negative bacilli. The multivariate analysis showed that the influencial factors for endoscope cleaning and disinfection are as follows: staffs responsible for the cleaning and sterilization of otolaryngology endoscopes, the standard for cleaning and disinfection process, and the frequency of endoscope use.
 The present situation of cleaning and sterilization for otolaryngology endoscopes is better in the top-class hospitals than that in the second-class hospitals. The sterilization and management of otolaryngology endoscopy are needed to be improved, and the staff training is needed, especially in the primary hospitals.

    Ores, waste tailings and slag, together with three typical soil profiles (natural soil profiles far from mine entrance and near mine entrance, soil profile under slag) in Chatian mercury mining deposit (CMD), western Hunan province were sampled and their concentrations of mercury (Hg), arsenic (As), lead (Pb), cadmium (Cd), zinc (Zn) were determined by HG-ICP-AES and ICP-MS. Enrichment factor and correlation analysis were taken to investigate the origins, distribution and migration of Hg, as well as other heavy metals in the CMD. The results show that Hg is enriched in the bottom of the soil profile far from mine entrance but accumulated in the surface of soil profiles near mine entrance and under slag. The soil profiles near mine entrance and under slag are both contaminated by Hg, while the latter is contaminated more heavily. In the soil profile under slag, Hg concentration in the surface soil, Hg average concentration in the total profile, and the leaching depth of soil Hg are 640 microg x g(-1), (76.74 +/- 171.71) microg x g(-1), and more than 100 cm, respectively; while 6.5 microg x g(-1), (2.74 +/- 1.90) microg x g(-1), and 40 cm, respectively, are found in the soil profile near mine entrance. Soil in the mercury mine area is also polluted by Cd, As, Pb, Zn besides metallogenic element Hg, among which Cd pollution is relatively heavier than others. The mobility of the studied heavy metals in soil follows the order as Hg > Cd > As > Zn approximately equal to Pb. The leaching depth of the heavy metals is influenced by total concentration in the surface soil and soil physico-chemical parameters. The origins, distribution and migration of heavy metals in soil profile in the mining area are related to primary geological environment, and strongly influenced by human mining activities.

    Eating away from home is associated with poor diet quality, in part due to less healthy food choices and larger portions. However, few studies account for the potential additional contribution of differences in food composition between restaurant- and home-prepared dishes. The present study aimed to investigate differences in nutrients of dishes prepared in restaurants v. at home. Eight commonly consumed dishes were collected in twenty of each of the following types of locations: small and large restaurants, and urban and rural households. In addition, two fast-food items were collected from ten KFC, McDonald's and food stalls. Five samples per dish were randomly pooled from every location. Nutrients were analysed and energy was calculated in composite samples. Differences in nutrients of dishes by preparation location were determined. Hunan Province, China. Na, K, protein, total fat, fatty acids, carbohydrate and energy in dishes. On average, both the absolute and relative fat contents, SFA and Na:K ratio were higher in dishes prepared in restaurants than households (P < 0·05). Protein was 15 % higher in animal food-based dishes prepared in households than restaurants (P<0·05). Quantile regression models found that, at the 90th quantile, restaurant preparation was consistently negatively associated with protein and positively associated with the percentage of energy from fat in all dishes. Moreover, restaurant preparation also positively influenced the SFA content in dishes, except at the highest quantiles. These findings suggest that compared with home preparation, dishes prepared in restaurants in China may differ in concentrations of total fat, SFA, protein and Na:K ratio, which may further contribute, beyond food choices, to less healthy nutrient intakes linked to eating away from home.

    Here, we aim to determine the distribution, ecological risk and sources of heavy metals and metalloids in the surface sediments of the Xiangjiang River, Hunan Province, China. Sixty-four surface sediment samples were collected in 16 sites of the Xiangjiang River, and the concentrations of ten heavy metals and metalloids (Mn, Zn, Cr, V, Pb, Cu, As, Ni, Co, and Cd) in the sediment samples were investigated using an inductively coupled plasma mass spectrometer (ICP-MS) and an atomic fluorescence spectrophotometer (AFS), respectively. The results showed that the mean concentrations of the ten heavy metals and metalloids in the sediment samples followed the order Mn > Zn > Cr > V > Pb > Cu > As ≈ Ni >Co > Cd. The geoaccumulation index (I geo ), enrichment factor (EF), modified degree of contamination (mC d ), and potential ecological risk index (RI) revealed that Cd, followed by Pb, Zn, and Cu, caused severely contaminated and posed very highly potential ecological risk in the Xiangjiang River, especially in Shuikoushan of Hengyang, Xiawan of Zhuzhou, and Yijiawan of Xiangtan. The Pearson's correlation coefficient (PCC) analysis, principal component analysis (PCA), and hierarchical cluster analysis (HCA) indicated that the ten heavy metals and metalloids in the sampling sediments of the Xiangjiang River were classified into three groups: (1) Cd, Pb, Zn, and Cu which possibly originated from Shuikoushan, Xiawan, and Yijiawan clustering Pb-Zn mining and smelting industries; (2) Co, V, Ni, Cr, and Al from natural resources; and (3) Mn and As. Therefore, our results suggest that anthropogenic activities, especially mining and smelting, have caused severe contamination of Cd, Pb, Zn, and Cu and posed very high potential ecological risk in the Xiangjiang River.

    To evaluate the status and influential factors for prenatal care and postpartum visit among pregnant women in Hunan Province from 2008 to 2013 based on the data from the First Health Service Survey in Hunan Province.
 Methods: Based on the data of prenatal care and postpartum visit among pregnant women from the First Health Service Survey of Hunan Province in 2013, proportion of pregnant women, who didn't meet the criteria for prenatal care and postpartum visit, were calculated (≥5 times for prenatal care and ≥2 times for postpartum visit, according to the National Basic Public Health Service program, 2009 Edition). Multivariable logistic regression models were used to identify the influencial factors.
 Results: A total of 1 035 eligible women were included in data analysis. The proportion of pregnant women who did not meet the criteria were 40.12% (95% CI 24.91%-55.33%) for prenatal care and 64.88% (95% CI 39.70%-90.06%) for postpartum visit. After adjusting other confounding factors, pregnant women with middle- and high-income had lower proportions of not meeting the criteria than those with low-income, with adjusted odds ratios of 0.41 and 0.39, respectively. Multiparae had higher proportion of not meeting the criteria than primiparas, with adjusted odds ratio of 1.54, and pregnant women with age 25-34 years and 35-64 years had lower proportions of not meeting the criteria than those with age 15-24 years. In term of postpartum visit, pregnant women with middle- to high-income had lower proportions of not meeting the criteria than those with low-income, with adjusted odds ratios of 0.50, 0.46 and 0.54, respectively; multiparae had higher proportion of not meeting the criteria than primiparas, with the adjusted odds ratio of 2.30.
 Conclusion: Proportions of pregnant women of not meeting the criteria are high in Hunan Province. Local government should strengthen the management to decrease the proportions of pregnant women who do not meet the standard in

    Objective: To analyze the status of personnel in occupational disease prevention and treatment institutions in Hunan Province, China, from 1996 to 2015, to predict staff composition using grey model (GM) (1, 1) , and to provide a scientific basis and reference for optimizing human resource planning of occupational disease prevention and treatment in other provinces and regions and promoting the service capacity of the institutions. Methods: The data of the staff in occupational disease prevention and treatment institutions in Hunan Province, China, from 1996 to 2015 were obtained from the established basic information management system. The descriptive analysis method was used to analyze the dynamic changes in number and composition of the staff and the GM (1, 1) was used to predict the staff composition. Results: The numbers of the staff members in 1996 and 2015 in occupational disease prevention and treatment institutions in Hunan Province, China were 1591 and 1429, respectively. In the twenty years, the main education level of the staff transformed from "technical secondary school education and non-academic qualifications" to "bachelor degree or above and college degree"; the main major of the staff transformed from "other majors" to "public health and clinical medicine"; the proportion of the staff members without professional titles changed from >1/3 to 5%; and the proportions of the staff members with senior, intermediate, and junior professional titles were steadily rising. GM prediction showed that the proportions of highly educated staff members in 2018 and 2020 would be up to 41.00% and 45.61%, respectively; and the proportions of the staff members with a major in public health in 2018 and 2020 would be up to 44.15% and 46.60%, respectively. Conclusion: The staff in occupational disease prevention and treatment institutions in Hunan Province, China, in the twenty years have slight changes in staff size and great improvement in staff quality, which is

    Full Text Available An increase in the incidence of hand, foot and mouth disease (HFMD cases has been observed in the Hunan province of mainland China since 2009 with a particularly higher level of severe cases in 2010-2012. Intestinal viruses of the picornaviridae family are responsible for the human syndrome associated with HFMD with enterovirus 71 (EV71 and Coxsackievirus A16 (Cox A16 being the most common causative strains. HFMD cases associated with EV71 are generally more severe with an increased association of morbidity and mortality. In this study, the etiology surveillance data of HFMD cases in Hunan province from March 2010 to October 2012 were analyzed to determine if there is a statistically relevant linear correlation exists between the detection rate of EV71 in mild cases and the proportion of severe cases among all HFMD patients. As the cases progressed from mild to severe to fatal, the likelihood of EV71 detection increased (25.78%, 52.20% and 84.18%, respectively. For all cases in the timeframe evaluated in this study, the presence of virus was detected in 63.21% of cases; among cases showing positivity for virus, EV71 infection accounted for 50.14%. These results provide evidence to support the observed higher morbidity and mortality associated with this outbreak and emphasizes the importance of early detection in order to implement necessary prevention measures to mitigate disease progression.

    In this paper, we took the leaves of shrubland plants in rocky desertification area in Southwestern Hunan as the research object to analyze the nitrogen (N) and phosphorus (P) stoichiometry characteristics for different functional groups and different grades of rocky desertification, i.e., light rocky desertification (LRD), moderate rocky desertification (MRD) and intense rocky desertification (IRD). The results showed that the average contents of N and P were 12.89 and 1.19 g·kg -1 , respectively, and N/P was 11.24 in common shrubland plants in the study area, which indicated that the growth of most plants were mainly limited by N. The content of N was declined in order of deciduous shrubs > evergreen shrubs > annual herbs > perennial herbs. The content of P and N/P were higher in deciduous shrubs than in perennial herbs. Significant differences were found among the main families of plants in terms of the contents of N, P and N/P in the study sites. The plants of Gramineae had the lowest contents of N and P, andtheir growth was mostly restricted by N, while Leguminosae had the highest content of N and N/P, and their productivity was majorly controlled by P. The contents of N and P in the leaves were significantly higher in dicotyledon plants and C3 plants than in monocotyledon plants and C4 plants, but the N/P was not significantly diffe-rent between these two plant categories. The nitrogen-fixing plants had higher content of N and N/P than the non-nitrogen-fixing plants, but the P content was not significantly different between these two plant groups. There were significant correlations between contents of N and P, N/P and N in all study plots. No significant correlation was found between N/P and P content in the examined rocky desertification sites, except for that in MRD. There were no significant differences of the contents of N, P and N/P under different grades of rocky desertification.

    In 1985, the collapse of the tailing dam in Chenzhou lead/zinc mine (Hunan, southern China) led to the spread of mining waste spills on the farmland along the Dong River. After the accident, an urgent soil cleaning up was carried out in some places. Seventeen years later, cereal (rice, maize, and sorghum), pulses (soybean, Adzuki bean, mung bean and peanut), vegetables (ipomoea, capsicum, taro and string bean) and the rooted soils were sampled at four sites: (1) the mining area (SZY), (2) the area still covered with the mining tailing spills (GYB), (3) the cleaned area from mining tailing spills (JTC), and (4) a background site (REF). Metal concentrations in the crops and soils were analyzed to evaluate the long-term effects of the spilled waste on the soil and the potential human exposure through food chains. The results showed that the physical-chemical properties of the soils obviously changed due to the different farming styles used by each individual farmer. Leaching effects and plant extraction of metals from some soils were quite weak. Certain soils were still heavily polluted with As, Cd, Zn, Pb and Cu. The contamination levels were in the order of GYB>SZY>JTC showing that the clean-up treatment was effective. The maximum allowable concentration (MAC) levels for Chinese agricultural soils were still highly exceeded, particularly for As and Cd (followed by Zn, Pb and Cu), with mean concentrations of 709 and 7.6 mg kg(-1), respectively. These concentrations exceed the MAC levels by 24 times for As and 13 times for Cd at GYB. Generally, the edible leaves or stems of crops were more heavily contaminated than seeds or fruits. Ipomoea was the most severely contaminated crop. The concentrations of Cd and Pb were 3.30 and 76.9 mg kg(-1) in ipomoea leaves at GYB, which exceeded the maximum permit levels (0.5 mg kg(-1) for Cd and 9 mg kg(-1) for Pb) by 6.6 and 8.5 times, respectively. Taro (+skin) could accumulate high concentrations of Zn and Cd in the edible stem

    Full Text Available Abstract Background There are growing concerns regarding inequities in health, with poverty being an important determinant of health as well as a product of health status. Within the People's Republic of China (P.R. China, disparities in socio-economic position are apparent, with the rural-urban gap of particular concern. Our aim was to compare direct and proxy methods of estimating household wealth in a rural and a peri-urban setting of Hunan province, P.R. China. Methods We collected data on ownership of household durable assets, housing characteristics, and utility and sanitation variables in two village-wide surveys in Hunan province. We employed principal components analysis (PCA and principal axis factoring (PAF to generate household asset-based proxy wealth indices. Households were grouped into quartiles, from 'most wealthy' to 'most poor'. We compared the estimated household wealth for each approach. Asset-based proxy wealth indices were compared to those based on self-reported average annual income and savings at the household level. Results Spearman's rank correlation analysis revealed that PCA and PAF yielded similar results, indicating that either approach may be used for estimating household wealth. In both settings investigated, the two indices were significantly associated with self-reported average annual income and combined income and savings, but not with savings alone. However, low correlation coefficients between the proxy and direct measures of wealth indicated that they are not complementary. We found wide disparities in ownership of household durable assets, and utility and sanitation variables, within and between settings. Conclusion PCA and PAF yielded almost identical results and generated robust proxy wealth indices and categories. Pooled data from the rural and peri-urban settings highlighted structural differences in wealth, most likely a result of localized urbanization and modernization. Further research is needed

    Hunan province, Central South China, is rich in mineral resources and also a well-known nonferrous metal base in China. Mining and ore processing there, however, are mostly conducted in indigenous methods, and thus causing heavy metal pollution of abundant farmland. Situated in northern Hunan province, Y county has antimony, manganese, vanadium, and pyrite mines, but still belongs to a region of rice cultivation, of which, paddy fields make up 84.5% of the total farmland. Our investigations found that irrigation water is threatened by the release of mining wastewater in the county. For example, a stream used for irrigation turns dark-red after long-term receiving wastewater discharged from a pyrite company at HS Town of the county. Concentrations of Cu, Zn, Cd, Fe and Mn in the stream water reach 0.03 mg kg-1, 2.14 mg kg-1, 0.02 mg kg-1, 96.0 mg kg-1 and 11.5 mg kg-1, respectively; these in the paddy soils nearby are 67.3 mg kg-1, 297 mg kg-1, 4.0 mg kg-1, 33.1 mg g-1 and 463 mg kg-1 on average, respectively, with a maximum of Cd reaching 16.8 mg kg-1. Microbial biomass and activities are significantly reduced by metal toxicity in the soils. The counts of fungal, actinomycin and bacterial colonies in the polluted soils are 8.8×103 /g (Fresh soil), 4.9×105 /g (Fresh soil) and 6.4×105 /g (Fresh soil), respectively, which are only 4.68%, 10.3% and 20.9% of these in non-polluted soils in Y county, respectively. Likewise, the microbial biomass (MB) - C and MB - N of the polluted soils are only 36.8% and 50.3% of these in the non-polluted, respectively. The activities of dehydrogenase, urease, catalase, acid and neutral phosphatase and sucrase in the polluted soils are only 41.2%, 49.8%, 56.8%, 69.9%, 80.7% and 81.0% of these in the non-polluted, respectively. There are significant negative correlations between Cu, Zn and Cd contents and the activities of dehydrogenase and catalase, suggesting that the two enzymes are the most sensitive to heavy metal toxicity in the

    The Indosinian granites in the South China Block (SCB) have important tectonic significance for the evolution of East Asia. Samples collected from Hunan Province can be geochemically classified into two groups. Group 1 is strongly peraluminous (A/CNK > 1.1), similar to S-type granites, and Group 2 has A/CNK = 1.0-1.1, with an affinity to I-type granites. Group 1 has lower FeOt, Al 2O 3, MgO, CaO, TiO 2 and ɛNd( t) values but higher K 2O + Na 2O, Rb/Sr, Rb/Ba and 87Sr/ 86Sr( t) than those of Group 2. Samples of both groups have similar LREE enriched pattern, with (Eu/Eu *) = 0.19-0.69, and strongly negative Ba, Sr, Nb, P and Ti anomalies. Geothermobarometry study indicates that the precursor magmas were emplaced at high-level depth with relatively low temperature (734-827 °C). Geochemical data suggest that Group 1 was originated from a source dominated by pelitic composition and Group 2 was from a mixing source of pelitic and basaltic rocks with insignificant addition of newly mantle-derived magma. Eight granitic samples in Hunan Province are dated at the cluster of 243-235 and 218-210 Ma by zircon U-Pb geochronology. Together with recent zircon U-Pb ages for other areas in the SCB, two age-clusters, including 243-228 Ma just after peak-metamorphism (˜ 246-252 Ma) and 220-206 Ma shortly after magma underplating event (˜224 Ma), are observed. It is proposed that in-situ radiogenic heating from the over-thickened crust induced dehydrated reaction of muscovite and epidote/zoisite to form the early Indosinian granites in response to the isostatic readjustments of tectonically thickened crust. Conductive heating from the underplating magma in the postcollisional setting triggered the formation of late Indosinian granites. Such a consideration is supported by the results from FLAC numerical simulation.

    The shifts of timing and length of the growing season (TLGS) are important indicators of crop response to climate change. With the help of satellite image data, it becomes feasible to retrieve the TLGS in a spatially continuous manner, which also accommodates local variation of TGSs. In this article, the TGSs of paddy rice in Hunan Province, China since 1995 was retrieved using times-series curves of MODIS Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Land Surface Water Index (LSWI). The change in TLGS and its connection to regional climate change was discussed. The results showed the advance of TGSs of double-season paddy rice and the reduction of GSL in the past 20 years, which is believed to be linked to the rise in the temperature and precipitation in the growth periods. Understanding the local variation and trend of TLGS influenced by climate change is essential for making agricultural adaptive policies to reduce the risk of crop damaged, also can provide key information for studying how multi-hazards affect crop exposure.

    Published research has not considered acute diseases and injuries in assessing the impact of varying disease counts on health-related quality of life (HRQoL). We used Chinese value sets of EQ-5D-3L to examine the relationship between the number of diseases individuals had (including chronic diseases, acute diseases and injuries) and their HRQoL. A total of 19 387 individuals aged 18 years and older were included in the study. Using data from the First Provincial Health Services Survey of Hunan, China, HRQoL was assessed with the EQ-5D-3L scale, a standardized instrument developed by the EuroQoL group. The EQ-5D-3L utility score was calculated using the Chinese EQ-5D-3L value set. This survey coded disease using the list of 133 conditions that was defined by the First Provincial Health Services Survey of Hunan, China, based on the 10th International Classification of Diseases. 126 conditions were disease-related and were therefore included in data analysis. Of 15 245 respondents, urban residents and male constituted 53.0% and 48.2%, respectively. 19.3% of respondents had one disease and 5.0% had at least two diseases. Of the five dimensions of the EQ-5D-3L, the pain/discomfort dimension had the highest proportion of moderate or serious problems among the respondents (14.4%, 95% CI 10.5% to 18.2%). The average Visual Analogue Scale (VAS) score and utility score were 78.0 (95% CI 76.9 to 79.1) and 0.958 (95% CI 0.946 to 0.970), respectively. Residents with 1 and ≥2 diseases had higher proportions of moderate or serious problems in five dimensions of the EQ-5D-3L scale during the previous 2 weeks than those without disease after controlling for location (urban/rural), sex, age, education level and household income, respectively (adjusted ORs: 3.1-3.7 and 4.4-6.6, respectively). The mean of the EQ VAS score was 8.4 and 13.6 points lower in respondents with 1 and ≥2 diseases than in respondents without disease; the corresponding mean score difference was 0

    Full Text Available Access to health care is a major requirement in improving health and fostering socioeconomic development. In the People's Republic of China (P.R. China, considerable changes have occurred in the social, economic, and health systems with a shift from a centrally planned to a socialist market economy. This brought about great benefits and new challenges, particularly for vertical disease control programs, including schistosomiasis. We explored systemic barriers in access to equitable and effective control of schistosomiasis.Between August 2002 and February 2003, 66 interviews with staff from anti-schistosomiasis control stations and six focus group discussions with health personnel were conducted in the Dongting Lake area, Hunan Province. Additionally, 79 patients with advanced schistosomiasis japonica were interviewed. The health access livelihood framework was utilized to examine availability, accessibility, affordability, adequacy, and acceptability of schistosomiasis-related health care.We found sufficient availability of infrastructure and human resources at most control stations. Many patients with advanced schistosomiasis resided in non-endemic or moderately endemic areas, however, with poor accessibility to disease-specific knowledge and specialized health services. Moreover, none of the patients interviewed had any form of health insurance, resulting in high out-of-pocket expenditure or unaffordable care. Reports on the adequacy and acceptability of care were mixed.There is a need to strengthen health awareness and schistosomiasis surveillance in post-transmission control settings, as well as to reduce diagnostic and treatment costs. Further studies are needed to gain a multi-layered, in-depth understanding of remaining barriers, so that the ultimate goal of schistosomiasis elimination in P.R. China can be reached.

    To forecast the future trend of betel nut-associated oral cancer and the resulting burden on health based on historical oral cancer patient data in Hunan province, China. Oral cancer patient data in five hospitals in Changsha (the capital city of Hunan province) were collected for the past 12 years. Three methods were used to analyse the data; Microsoft Excel Forecast Sheet, Excel Trendline, and the Logistic growth model. A combination of these three methods was used to forecast the future trend of betel nut-associated oral cancer and the resulting burden on health. Betel nut-associated oral cancer cases have been increasing rapidly in the past 12  years in Changsha. As of 2016, betel nuts had caused 8,222 cases of oral cancer in Changsha and close to 25,000 cases in Hunan, resulting in about ¥5 billion in accumulated financial loss. The combined trend analysis predicts that by 2030, betel nuts will cause more than 100,000 cases of oral cancer in Changsha and more than 300,000 cases in Hunan, and more than ¥64 billion in accumulated financial loss in medical expenses. The trend analysis of oral cancer patient data predicts that the growing betel nut industry in Hunan province will cause a humanitarian catastrophe with massive loss of human life and national resources. To prevent this catastrophe, China should ban betel nuts and provide early oral cancer screening for betel nut consumers as soon as possible.

    A 33-cm long aragonite stalagmite, LHN-1, from Lianhua Cave (29°09'N, 109°33'E , 459m a.s.l.) in NW Hunan Province of China has been dated by ICP-MS 230Th/U method. The 14 230Th/U dates with less than ×37 years uncertainties yield excellent chronology, showing that the stalagmite grew continuously over the past 3400 years. The 0.1-mm sampling interval for stable isotope analyses provides annual resolution δ18O and δ13C records of the LHN-1 stalagmite. Up-to-dated, a total of 887 measurements for δ18O and δ13C have been made, which reveal detailed monsoonal climatic changes during the past 1000 years. The average values of δ18O and δ13C are -5.83 (‰, PDB) and -3.29 (‰, PDB), respectively. For the youngest part of the δ18O record, we have compared with the instrumentally meteorological records and historical dryness/wetness indexes from the studying area, indicating that stalagmite δ18O on annual-to-decadal scales reflects mainly rainfall change in the monsoonal area, with lighter δ18O reflecting wetter condition. The comparison of the δ18O with the East Asian Summer Monsoon (EASM) index since AD 1850 adopted by IPCC (2007) illustrates that lighter stalagmite δ18O corresponds to stronger EASM. Taking the average δ18O value of the 1000-yr record as an average climatic condition, we have found that the δ18O values during AD 1050~1100, 1125~1225, 1300~1350, 1430~1630 and 1900~1960 are lighter than the average, reflecting stronger EASM and wetter condition. The δ18O values during AD 1100~1125, 1225~1300, 1350~1430, 1630~1900 and 1960 to the present are heavier than the average, indicating weak EASM and drier condition. On decadal-to-centennial scales, the δ13C variations generally follow that of δ18O which probably demonstrates that vegetation above the cave controls the δ13C variations. Further comparisons of the δ18O, EASM, ENSO and PDO show that a negative SOI (El Nino phase) correlates warm PDO phase and higher N. Pacific pressure, resulting

    Separating out the influence of climatic trend, fluctuations and extreme events on crop yield is of paramount importance to climate change adaptation, resilience, and mitigation. Previous studies lack systematic and explicit assessment of these three fundamental aspects of climate change on crop yield. This research attempts to separate out the impacts on rice yields of climatic trend (linear trend change related to mean value), fluctuations (variability surpassing the "fluctuation threshold" which defined as one standard deviation (1 SD) of the residual between the original data series and the linear trend value for each climatic variable), and extreme events (identified by absolute criterion for each kind of extreme events related to crop yield). The main idea of the research method was to construct climate scenarios combined with crop system simulation model. Comparable climate scenarios were designed to express the impact of each climate change component and, were input to the crop system model (CERES-Rice), which calculated the related simulated yield gap to quantify the percentage impacts of climatic trend, fluctuations, and extreme events. Six Agro-Meteorological Stations (AMS) in Hunan province were selected to study the quantitatively impact of climatic trend, fluctuations and extreme events involving climatic variables (air temperature, precipitation, and sunshine duration) on early rice yield during 1981-2012. The results showed that extreme events were found to have the greatest impact on early rice yield (-2.59 to -15.89%). Followed by climatic fluctuations with a range of -2.60 to -4.46%, and then the climatic trend (4.91-2.12%). Furthermore, the influence of climatic trend on early rice yield presented "trade-offs" among various climate variables and AMS. Climatic trend and extreme events associated with air temperature showed larger effects on early rice yield than other climatic variables, particularly for high-temperature events (-2.11 to -12

The in situ perfusion method was used in rats to study the absorption mechanisms of an oil-in-water (O/W microemulsion (O/W-ME and a water-in-oil (W/O microemulsion (W/O-ME. The possibility of lymphatic transport of the MEs was investigated using a chylomicron flow blocking approach. The results for the absorption mechanisms in the stomach and intestines indicated that the absorption characteristics of the O/W-ME and W/O-ME depend on the segment. The W/O-ME had higher internal membrane permeability than the O/W-ME. The results of the lymphatic transport analyses showed that both the O/W-ME and W/O-ME underwent lymphatic transport and that this pathway was a major contributor to the oral bioavailability of MEs. Furthermore, the type of ME can significantly affect the absorption of puerarin through the lymphatic system due to the oil content and the form of the microemulsion after oral administration. In conclusion, these data indicate that microemulsions are an effective and promising delivery system to enhance the oral bioavailability of poorly water-soluble drugs.Keywords: microemulsion, lymphatic transport, oral bioavailability, chylomicron

Two muscovite samples from ore-bearing quartz vein yielded 40Ar/39Ar plateau ages of 156.6 ± 0.7 Ma, 149.5 ± 0.8 Ma, respectively. Combined with the geological evidence, two metallogenic events are proposed in the Xitian ore field, with skarn-type W-Sn mineralization in Late Triassic (Indosinian and quartz vein/greisen type W-Sn mineralization in Late Jurassic (Yanshanian. The relatively low Ce/Ce* ratios and high Y/Ho ratios in zircons from two altered granites indicate that the hydrothermal fluids of two metallogenic events are characterized by low oxygen fugacities and enrichment in F. The similar chondrite-normalized patterns between the skarn and Xitian Indosinian granites and Sr-Nd-Pb isotopic compositions of wolframite suggest that the metal sources for both types W-Sn mineralization are derived from a crustal source.

    The use of computers in China's water conservancy and hydropower construction began in the 1960s for exploration surveys, planning, design, construction, operation, and scientific research. Despite the positive results, and the formation of a 1000-person computer computation contingent, computer development among different professions is not balanced. The weaknesses and disparities in computer applications includes an overall low level of application relative to the rest of the world, which is partly due to inadequate hardware and programs. The report suggests five ways to improve applications and popularize microcomputers which emphasize leadership and planning.

    Full Text Available In South China, both crustal reworking and crust–mantle interaction were important geological processes during the Paleozoic and Mesozoic eras. However, the relationships between these two processes and metal mineralization are still unknown. Here we report rhenium and osmium isotopic data for pyrite grains from a pyrite deposit associated with a granite intrusion in the Shangbao area, southeastern Hunan Province (South China. Two pyrite samples, both containing many euhedral pyrite grains, were collected from the same locality, but the samples yield distinct ages. Six euhedral pyrite grains from one sample yield an isochronal age of 279 ± 12 Ma, with an initial 187Os/188Os ratio of 0.39 ± 0.71, and Re and Os concentrations of 0.12–63.5 ppb and 2.14–185 ppt, respectively. This Early Permian age is in good agreement with the age of the strata that host the pyrite deposit. Five euhedral pyrite grains from the other sample yield an isochronal age of 75.2 ± 4.3 Ma, with an initial 187Os/188Os ratio of 0.141 ± 0.030 and Re and Os concentrations of 0.15–0.43 ppb and 1.0–39.9 ppt, respectively. If one pyrite grain with the highest 187Re/188Os and 187Os/188Os ratios is excluded, other four pyrite grains give an isochronal age of 85 ± 13 Ma. The Late Cretaceous age (75–85 Ma is consistent with the zircon U–Pb age of the Shangbao granites (80.1 ± 0.3 Ma to within uncertainties. Considering also the relatively lower radiogenic initial 187Os/188Os ratio of this sample, we suggest that the later stage pyrite ore was probably formed through crystallization from the magmatic hydrothermal fluids. Combined with other geological and associated magmatic data, we propose a skarn-related fluid–ore interaction process to explain the second stage of metallogenesis in the Shangbao pyrite deposit. The Early Permian pyrite ore was deposited in a brine basin with evaporites during the Early Permian. Later magmatic hydrothermal

Since symptoms, signs and radiographic characteristics of pituitary abscess are similar to several other pituitary lesions, correct diagnosis before surgery is challenging. In this article, two cases of pituitary abscess treated in our department are reported, followed by a literature review. In these two cases, both patients presented with intermittent fever. Magnetic resonance imaging revealed a suprasellar lesion with rim enhancement after contrast injection. After transsphenoidal surgery, the diagnosis of pituitary abscess was confirmed. The patients were then given antibiotic treatment and recovered fully in less than 2 months. Findings of this article support timely diagnosis and proper treatment including transsphenoidal surgery and antibiotic therapy for pituitary abscess, leading to lower mortality rates and higher probability of pituitary hormone function recovery. Keywords: pituitary abscess, transsphenoidal resection, antibiotic therapy, diagnosis

    Technological cycles have been characterized as the basis of long and continuous periods economic growth through sustained changes in total factor productivity. While this hypothesis is in part consistent with several theories of growth, the sheer magnitude and length of the economic revolutions experienced by humankind seems to indicate surmise that more attention should be given to the origin of major technological and economic changes, with reference to one crucial question: role of production and use of energy in economic development.

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

    The globalization of the economy and the end of the Cold War have triggered many changes in the traditional practices of U.S. industry. To effectively apply the resources available to the United States, the federal government has firmly advocated a policy of technology transfer between private industry and government labs, in this case the National Aeronautics and Space Administration (NASA). NASA Administrator Daniel Goldin is a strong proponent of this policy and has organized technology transfer or commercialization programs at each of the NASA field centers. Here at Langley Research Center, the Technology Applications Group (TAG) is responsible for facilitating the transfer of Langley developed research and technology to U.S. industry. Entering the program, I had many objectives for my summer research with TAG. Certainly, I wanted to gain a more thorough understanding of the concept of technology transfer and Langley's implementation of a system to promote it to both the Langley community and the community at large. Also, I hoped to become more familiar with Langley's research capabilities and technology inventory available to the public. More specifically, I wanted to learn about the technology transfer process at Langley. Because my mentor is a member of Materials and Manufacturing marketing sector of the Technology Transfer Team, another overriding objective for my research was to take advantage of his work and experience in materials research to learn about the Advanced Materials Research agency wide and help market these developments to private industry. Through the various projects I have been assigned to work on in TAG, I have successfully satisfied the majority of these objectives. Work on the Problem Statement Process for TAG as well as the development of the Advanced Materials Research Brochure have provided me with the opportunity to learn about the technology transfer process from the outside looking in and the inside looking out.

    The CEA is an organization with a primarily technological focus, and one of the key areas in which it carries out research is Health Technology. This field of research was recognized and approved by the French Atomic Energy Committee on July 20, 2004. The expectations of both the public and health care professionals relate to demands for the highest standards of health care, at minimum risk. This implies a need to diagnose illness and disease as accurately and as at early a stage as possible, to target surgery precisely to deal only with damaged organs or tissues, to minimize the risk of side effects, allergies and hospital-acquired infections, to follow-up and, as far as possible, tailor the health delivery system to each individual's needs and his or her lifestyle. The health care sector is subject to rapid changes and embraces a vast range of scientific fields. It now requires technological developments that will serve to gather increasing quantities of useful information, analyze and integrate it to obtain a full understanding of highly complex processes and to be able to treat the human body as un-invasively as possible. All the technologies developed require assessment, especially in the hospital environment. (authors)

The traveler also attended the Fourth International Conference on Environmental Contamination in Barcelona. Conference topics included environmental chemistry, land disposal of wastes, treatment of toxic wastes, micropollutants, trace organics, artificial radionuclides in the environment, and the use biomonitoring and biosystems for environmental assessment. The traveler presented a paper on The Fate of Radionuclides in Sewage Sludge Applied to Land.'' Those findings corresponded well with results from studies addressing the fate of fallout radionuclides from the Chernobyl nuclear accident. There was an exchange of new information on a number of topics of interest to DOE waste management and environmental restoration needs.

  19. Photovoltaic technologies

    Bagnall, Darren M.; Boreland, Matt

    2008-01-01

    Photovoltaics is already a billion dollar industry. It is experiencing rapid growth as concerns over fuel supplies and carbon emissions mean that governments and individuals are increasingly prepared to ignore its current high costs. It will become truly mainstream when its costs are comparable to other energy sources. At the moment, it is around four times too expensive for competitive commercial production. Three generations of photovoltaics have been envisaged that will take solar power into the mainstream. Currently, photovoltaic production is 90% first-generation and is based on silicon wafers. These devices are reliable and durable, but half of the cost is the silicon wafer and efficiencies are limited to around 20%. A second generation of solar cells would use cheap semiconductor thin films deposited on low-cost substrates to produce devices of slightly lower efficiency. A number of thin-film device technologies account for around 5-6% of the current market. As second-generation technology reduces the cost of active material, the substrate will eventually be the cost limit and higher efficiency will be needed to maintain the cost-reduction trend. Third-generation devices will use new technologies to produce high-efficiency devices. Advances in nanotechnology, photonics, optical metamaterials, plasmonics and semiconducting polymer sciences offer the prospect of cost-competitive photovoltaics. It is reasonable to expect that cost reductions, a move to second-generation technologies and the implementation of new technologies and third-generation concepts can lead to fully cost-competitive solar energy in 10-15 years.

  20. Vacuum Technology

    Energy Technology Data Exchange (ETDEWEB)

    Biltoft, P J

    2004-10-15

    The environmental condition called vacuum is created any time the pressure of a gas is reduced compared to atmospheric pressure. On earth we typically create a vacuum by connecting a pump capable of moving gas to a relatively leak free vessel. Through operation of the gas pump the number of gas molecules per unit volume is decreased within the vessel. As soon as one creates a vacuum natural forces (in this case entropy) work to restore equilibrium pressure; the practical effect of this is that gas molecules attempt to enter the evacuated space by any means possible. It is useful to think of vacuum in terms of a gas at a pressure below atmospheric pressure. In even the best vacuum vessels ever created there are approximately 3,500,000 molecules of gas per cubic meter of volume remaining inside the vessel. The lowest pressure environment known is in interstellar space where there are approximately four molecules of gas per cubic meter. Researchers are currently developing vacuum technology components (pumps, gauges, valves, etc.) using micro electro mechanical systems (MEMS) technology. Miniature vacuum components and systems will open the possibility for significant savings in energy cost and will open the doors to advances in electronics, manufacturing and semiconductor fabrication. In conclusion, an understanding of the basic principles of vacuum technology as presented in this summary is essential for the successful execution of all projects that involve vacuum technology. Using the principles described above, a practitioner of vacuum technology can design a vacuum system that will achieve the project requirements.

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    The theme of the International Biohydrometallurgy Symposium held in Jackson Hole, Wyoming, August 22-25, 1993, is ''Biohydrometallurgy: An Industry Matures.'' This is a developing technology which made important contributions to the minerals industry. Biohydrometallurgical technology was first introduced into the copper industry and subsequently to the uranium industry for the production of metal values from low-grade mineral resources. Currently, biotechnology has advanced a step further. It is now commercially applied for the treatment of high-grade refractory gold ores in aerated stirred reactors to liberate precious metals for cyanidation. In addition, the industrial applications of biotechnology involve bioenhanced tertiary oil recovery processes, which contribute to an increase in oil production from previously exhausted wells. Furthermore, many bioremediation technologies are being developed for the removal of toxic heavy metals and radionuclides from contaminated soils and aqueous mining and industrial effluents. This volume contains papers selected for publication which are predominantly dealing with subjects related to laboratory and industrial scale bioleaching of base and precious metals, biocorrosion phenomena, diverse bioreduction processes and electrochemical reactions. Individual papers have been processed separately for inclusion in the appropriate data bases

Different surface structures and properties were acquired by different coating times. Surface morphology, chemical composition, microstructure, pore size distribution, and hydrophilicity of the PLGA-MBG scaffold were characterized. Results of scanning electron microscopy indicated that MBG surface coating made the scaffold rougher with the increase of MBG content. Scaffolds after MBG modification possessed mesoporous architecture on the surface. The measurements of the water contact angles suggested that the incorporation of MBG into the PLGA scaffold improved the surface hydrophilicity. An energy dispersive spectrometer evidenced that calcium-deficient carbonated hydroxyapatite formed on the PLGA-MBG scaffolds

MC is not commonly practiced among Chinese males and little is known about the factors associated with their knowledge of and willingness for MC. This study was to explore the knowledge regarding the foreskin among Chinese males and to identify factors associated with their willingness to undergo circumcision.A total of 237 patients with redundant prepuce/phimosis were interviewed through face-to-face interviews. The items on the questionnaire included: demographics, an objective scale assessing knowledge about the foreskin, willingness to have MC, the attitudes of sexual partners and doctors toward redundant prepuce/phimosis, and the approaches that patients used to acquire knowledge regarding the prepuce. Univariate analysis and multiple logistic regression analysis were performed to identify factors that are associated with willingness to be circumcised (WTC.A total of 212 patients completed the interview. Multivariable logistic regression showed that three factors were significantly associated with WTC: being married (OR = 0.43, perceiving redundant prepuce/phimosis as a disease (OR = 1.93, and if a patient's partner supported MC (OR = 1.39. 58% (n = 122 had received information about the foreskin from another party: 18% (n = 37 from school, 8% (n = 17 from family, 17% (n = 36 from friends, 27% (n = 57 from health care providers. About 4% (n = 8 believed that their partners disliked their redundant prepuce/phimosis. 20% (n = 42 had received doctors' advice to undergo circumcision.Knowledge about the foreskin was low among Chinese males. Our study elucidates the factors associated with WTC and suggests that more education of the population about the foreskin can help improve the recognition of a correctible abnormality and help patients assess the potential role of MC in their health.

    Full Text Available Existing thermal comfort field studies are mainly focused on the relationship between the indoor physical environment and the thermal comfort. In numerous chamber experiments, physiological parameters were adopted to assess thermal comfort, but the experiments’ conclusions may not represent a realistic thermal environment due to the highly controlled thermal environment and few occupants. This paper focuses on determining the relationships between upper extremity skin temperatures (i.e., finger, wrist, hand and forearm and the indoor thermal comfort. Also, the applicability of predicting thermal comfort by using upper extremity skin temperatures was explored. Field studies were performed in office buildings equipped with split air-conditioning (SAC located in the hot summer and cold winter (HSCW climate zone of China during the summer of 2016. Psychological responses of occupants were recorded and physical and physiological factors were measured simultaneously. Standard effective temperature (SET* was used to incorporate the effect of humidity and air velocity on thermal comfort. The results indicate that upper extremity skin temperatures are good indicators for predicting thermal sensation, and could be used to assess the thermal comfort in terms of physiological mechanism. In addition, the neutral temperature was 24.7 °C and the upper limit for 80% acceptability was 28.2 °C in SET*.

    Wearable technology projects, to be useful, in the future, must be seamlessly integrated with the Flight Deck of the Future (F.F). The lab contains mockups of space vehicle cockpits, habitat living quarters, and workstations equipped with novel user interfaces. The Flight Deck of the Future is one element of the Integrated Power, Avionics, and Software (IPAS) facility, which, to a large extent, manages the F.F network and data systems. To date, integration with the Flight Deck of the Future has been limited by a lack of tools and understanding of the Flight Deck of the Future data handling systems. To remedy this problem it will be necessary to learn how data is managed in the Flight Deck of the Future and to develop tools or interfaces that enable easy integration of WEAR Lab and EV3 products into the Flight Deck of the Future mockups. This capability is critical to future prototype integration, evaluation, and demonstration. This will provide the ability for WEAR Lab products, EV3 human interface prototypes, and technologies from other JSC organizations to be evaluated and tested while in the Flight Deck of the Future. All WEAR Lab products must be integrated with the interface that will connect them to the Flight Deck of the Future. The WEAR Lab products will primarily be programmed in Arduino. Arduino will be used for the development of wearable controls and a tactile communication garment. Arduino will also be used in creating wearable methane detection and warning system.

    Full Text Available We are facing radical changes in our ways of living in the nearest future. Not necessarily of our own choice, but because tchnological development is moving so fast, that it will have still greater impact on many aspects of our lives. We have seen the beginnings of that change within the latest 35 years or so, but according to newest research that change will speed up immensely in the nearest years to come. The impact of that change or these changes will affect our working life immensely as a consequence of automation. How these changes are brought about and which are their consequences in a broad sense is being attempted to be understood and guessed by researchers. No one knows for sure, but specific patterns are visible. This paper will not try to guess, what will come, but will rather try to understand the deepest ”nature” of technology in order to understand the driving factors in this development: the genesis of technology in a broad sense in order to contibute to the understanding of the basis for the expected development.

    In recent days, energy security is becoming a major global concern and it has been recognized that a major reduction in greenhouse-gas emissions is required to combat climate change. Considerable expansion and new introduction of nuclear power generation are currently being planned and considered for the further in various parts of the world. Nuclear technologies of the latest 10 years in Japan were reviewed with their characteristics, advancement and future perspective. Steady efforts have been made to construct new nuclear power stations with computer-aided engineering system and modular and prefabricated structures, extend the interval of periodic inspections under the new inspection system that should improve both safety and reliability, implement advanced measures against aging and develop the next-generation light water reactors including a medium small reactor. Export of nuclear power plants has been promoted with international business alliance or cooperation. Activities to close nuclear fuel cycle to ensure sustainable nuclear energy utilization have been promoted. Decommissioning technologies for Tokai power station have been developed and accumulated know-how will be utilized in light water reactors. (T. Tanaka)

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    A question of the 1980s is how will contraceptive technology contribute to improving family planning services to meet the goal of making available a simple, safe, effective, and widely acceptable contraceptive method. Significant changes in existing technology in the 1970s resulted in safer and more effective contraceptive methods. Voluntary sterilization emerged as the primary method in developed and developing countries, as important modifications simplified the procedure for women. The tolerance and effectiveness of the IUD were improved by reducing its size, adding copper to its surface, or encapsulating progesterone within it. The steroid content of the birth control pill was reduced 10-fold, leading to fewer side effects, and the pill was found to be an effective postcoital contraceptive when taken at specific intervals. Vacuum aspiration for the termination of 1st trimester pregnancy proved to be 1 of the safest surgical techniques practiced. Belated attention is now being focused on adapting existing contraceptive methods for use during the postpartum period and breast feeding. The insertion of an IUD immediately following childbirth is a particularly useful option in the developing world as an increasing number of women have their babies in urban hospitals. A method of enhancing the contraceptive effect of breast feeding should neither change milk production nor transfer the drug to the nursing infant. Fortunately, progestin-only pills have been found to have no effect on breast milk and an attempt is being made to expand the use of this approved method. More simplification of female sterilization is needed. Current techniques require back-up facilities in case of complications and are unlikely to meet the developing world's enormous demand. 2 methods not widely used -- spermicides and periodic abstinence -- are coming under new scrutiny. In mid-1983 the US Food and Drug Administration approved a spermicide-impregnanated disposable sponge for over

    2013-01-01

    Waste incineration is the art of completely combusting waste, while maintaining or reducing emission levels below current emission standards. Where possible, objectives include the recovering of energy as well as the  combustion residues.  Successful waste incineration makes it possible to achieve a deep reduction in waste volume, obtain a compact and sterile residue, and eliminate a wide array of pollutants. This book places waste incineration within the wider context of waste management, and demonstrates that, in contrast to landfills and composting, waste incineration can eliminate objectionable and hazardous properties such as flammability and toxicity, result in a significant reduction in volume, and destroy gaseous and liquid waste streams leaving little or no residues beyond those linked to flue gas neutralization and treatment. Moreover, waste incineration sterilizes and destroys putrescible matter, and produces usable heat.  Incineration Technologies first appeared as a peer-reviewed contribution ...

    Powder technology is experiencing nowadays a great development and has broad application in different fields: nuclear energy, medicine, new energy sources, industrial and home artifacts, etc. Ceramic materials are of daily use as tableware and also in the building industry (bricks, tiles, etc.). However, in machine construction its utilization is not so common. The same happens with metals: powder metallurgy is employed less than traditional metal forming techniques. Both cases deal with powder technology and the forming techniques as far as the final consolidation through sintering processes are very similar. There are many different methods and techniques in the forming stage: cold-pressing, slip casting, injection molding, extrusion molding, isostatic pressing, hot-pressing (which involves also the final consolidation step), etc. This variety allows to obtain almost any desired form no matter how complex it could be. Some applications are very specific as in the case of UO 2 pellets (used as nuclear fuels) but with the same technique and other materials, it is possible to manufacture a great number of different products. This work shows the characteristics and behaviour of two magnetic ceramic materials (ferrites) fabricated in the laboratory of the Applied Research Division of the Bariloche Atomic Center for different purposes. Other materials and products made with the same method are also mentioned. Likewise, densities and shrinkage obtained by different methods of forming (cold-pressing, injection molding, slip casting and extrusion molding) using high-purity alumina (99.5% Al 2 O 3 ). Finally, different applications of such methods are given. (Author) [es

    Since 2006 NASA has been formulating robotic missions to the lunar surface through programs and projects like the Robotic Lunar Exploration Program, Lunar Precursor Robotic Program, and International Lunar Network. All of these were led by NASA Marshall Space Flight Center (MSFC). Due to funding shortfalls, the lunar missions associated with these efforts, the designs, were not completed. From 2010 to 2013, the Robotic Lunar Lander Development Activity was funded by the Science Mission Directorate (SMD) to develop technologies that would enable and enhance robotic lunar surface missions at lower costs. In 2013, a requirements-driven, low-cost robotic lunar lander concept was developed for the Resource Prospector Mission. Beginning in 2014, The Advanced Exploration Systems funded the lander team and established the MSFC, Johnson Space Center, Applied Physics Laboratory, and the Jet Propulsion Laboratory team with MSFC leading the project. The lander concept to place a 300-kg rover on the lunar surface has been described in the New Technology Report Case Number MFS-33238-1. A low-cost lander concept for placing a robotic payload on the lunar surface is shown in figures 1 and 2. The NASA lander team has developed several lander concepts using common hardware and software to allow the lander to be configured for a specific mission need. In addition, the team began to transition lander expertise to United States (U.S.) industry to encourage the commercialization of space, specifically the lunar surface. The Lunar Cargo Transportation and Landing by Soft Touchdown (CATALYST) initiative was started and the NASA lander team listed above is partnering with three competitively selected U.S. companies (Astrobotic, Masten Space Systems, and Moon Express) to develop, test, and operate their lunar landers.

    Thanks to Spatial Information Technologies (SITs) such as Remote Sensing (RS) and Geographical Information System (GIS) that are being quickly developed and updated, SITs are being used more widely in the public health field. The use of SITs to study the characteristics of the temporal and spatial distribution of Schistosoma japonicum and to assess the risk of infection provides methods for the control and prevention of schistosomiasis japonica has gradually become a hot topic in the field. The purpose of the present paper was to use RS and GIS technology to develop an efficient method of prediction and assessment of the risk of schistosomiasis japonica. We choose the Yueyang region, close to the east DongTing Lake (Hunan Province, China), as the study area, where a recent serious outbreak of schistosomiasis japonica took place. We monitored and evaluated the transmission risk of schistosomiasis japonica in the region using SITs. Water distribution data were extracted from RS images. The ground temperature, ground humidity and vegetation index were calculated based on RS images. Additionally, the density of oncomelania snails, which are the Schistosoma japonicum intermediate host, was calculated on the base of RS data and field measurements. The spatial distribution of oncomelania snails was explored using SITs in order to estimate the area surrounding the residents with transmission risk of schistosomiasis japonica. Our research result demonstrated: (1) the risk factors for the transmission of schistosomiasis japonica were closely related to the living environment of oncomelania snails. Key factors such as water distribution, ground temperature, ground humidity and vegetation index can be quickly obtained and calculated from RS images; (2) using GIS technology and a RS deduction technique along with statistical regression models, the density distribution model of oncomelania snails could be quickly built; (3) using SITs and analysis with overlaying population

    The concept of living technology-that is, technology that is based on the powerful core features of life-is explained and illustrated with examples from artificial life software, reconfigurable and evolvable hardware, autonomously self-reproducing robots, chemical protocells, and hybrid electronic-chemical systems. We define primary (secondary) living technology according as key material components and core systems are not (are) derived from living organisms. Primary living technology is currently emerging, distinctive, and potentially powerful, motivating this review. We trace living technology's connections with artificial life (soft, hard, and wet), synthetic biology (top-down and bottom-up), and the convergence of nano-, bio-, information, and cognitive (NBIC) technologies. We end with a brief look at the social and ethical questions generated by the prospect of living technology.

  20. Emerging environmental technologies and environmental technology policy

    Science.gov (United States)

    Clarke, Leon Edward

    This dissertation explores the role and design of environmental technology policy when environmental innovation is embodied in emerging environmental technologies such as photovoltaic cells or fuel cells. The dissertation consists of three individual studies, all of which use a simplified, general model industry between an emerging environmental technology and an entrenched, more-polluting technology. It clarifies the situations in which environmental technology policy can achieve high welfare and those in which it cannot; and it separates the possible situations an emerging environmental technology might face into four scenarios, each with its own technology policy recommendations. The second study attempts to clarify which of two factors is having a larger limiting effect on private investment in photovoltaics: the failure to internalize the environmental costs of fossil fuel electricity generation or a broad set of innovation market failures that apply to innovation irrespective of environmental concerns. The study indicates that innovation market failures are probably having a significantly larger impact than incomplete internalization. The third study explores the effectiveness of adoption subsidies at encouraging private-sector innovation. The conclusion is that adoption subsidies probably have only a limited effect on long-term, private-sector research. Two important general conclusions of the dissertation are (1) that optimal technology policy should begin with technology-push measures and end with demand-pull measures; and (2) that the technological response to internalization instruments, such as emissions taxes, may be highly nonlinear.

    The effort to comprehend innovation across cultures and time highlights the importance of the explicating factors external to technology. It becomes relevant to nuance or differentiate the understanding of social and cultural responses to adopted technologies by recognizing that technology shapes...... culture, and just as importantly that culture shapes technology. By looking at a recent transfer of technology this reciprocal exchange is elaborated by considering the cultural or contextual influence in the adaptation of technology. In this connection the notion of technological style is revisited...... by questioning whether it pays due attention to the non-technical factors of the process? In order to compensate for the deficiencies of the technological style as a sensitizing device the concept of sociotechnical style is introduced – a concept more in tune with resent research in technology studies....

  6. Focus on Technologies: Worry or Technology?

    Directory of Open Access Journals (Sweden)

    Saulius Kanišauskas

    2015-10-01

    Full Text Available The paper analyses different attitudes towards technologies in contemporary philosophical discourses. It points out that classical notion of technology formulated by Martin Heidegger seems to be more and more often questioned and even forgotten. As a result, it is being replaced by the theory of determinism, according to which the change of technologies determines the changes in social systems, the human being including. This happens this way and not vice versa. Nowadays technē, or “technika” (in English: technology is mostly understood in the instrumental meaning or in the meaning of power. It is considered to be a powerful means, tool or mechanism to influence, change, control and manipulate human consciousness and human feelings. Despite the fact that technologies have already been tamed, the problem of huge responsibility for using and developing them arises. It is questioned whether the increasing society’s attention to modern technologies is not a particular “technology” of the postmodern capitalism to manipulate social consciousness. In parallel with “yes” answer to this question, Albert Borgmann’s idea that the causes of technological development have an ontological dimension, i.e. the causes are rooted in the nature of human beings themselves and their desire to adore own creativity, is discussed. Thus, it becomes necessary to probe deeper into the nature of creativity.

    2014-09-01

    Technology alone will not be able to solve adaptation challenges, but it is likely to play an important role. As a result of the role of technology in adaptation and the importance of international collaboration for climate change, technology transfer for adaptation is a critical but understudied issue. Through an analysis of Global Environment Facility-managed adaptation projects, we find there is significantly more technology transfer occurring in adaptation projects than might be expected given the pessimistic rhetoric surrounding technology transfer for adaptation. Most projects focused on demonstration and early deployment/niche formation for existing technologies rather than earlier stages of innovation, which is understandable considering the pilot nature of the projects. Key challenges for the transfer process, including technology selection and appropriateness under climate change, markets and access to technology, and diffusion strategies are discussed in more detail.

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

  11. Advanced manufacturing: Technology diffusion

    Energy Technology Data Exchange (ETDEWEB)

    Tesar, A.

    1995-12-01

    In this paper we examine how manufacturing technology diffuses rom the developers of technology across national borders to those who do not have the capability or resources to develop advanced technology on their own. None of the wide variety of technology diffusion mechanisms discussed in this paper are new, yet the opportunities to apply these mechanisms are growing. A dramatic increase in technology diffusion occurred over the last decade. The two major trends which probably drive this increase are a worldwide inclination towards ``freer`` markets and diminishing isolation. Technology is most rapidly diffusing from the US In fact, the US is supplying technology for the rest of the world. The value of the technology supplied by the US more than doubled from 1985 to 1992 (see the Introduction for details). History shows us that technology diffusion is inevitable. It is the rates at which technologies diffuse to other countries which can vary considerably. Manufacturers in these countries are increasingly able to absorb technology. Their manufacturing efficiency is expected to progress as technology becomes increasingly available and utilized.

    Energy Technology Data Exchange (ETDEWEB)

    Alva, E N

    1978-01-01

    The concept of human settlements technology (HST) is described and applied to the unique needs of developing countries having different cultural and climatic conditions. These countries are experiencing rapid growth in population, and appropriate technology should not be assumed to be the same as that used in industrialized counties in temperate climates. A new world order is asking that emerging countries define their own living patterns and determine which technologies are suitable for their whole population's needs rather than limiting modern technology to an elite. The author describes how unconventional, but creative, energy can be tapped for housing construction that is low-cost, self-sufficient, and easy to service. A plurality of life styles in tune with the ecosystem could be adopted, but this will require politicians and architects to approach eco-design as a creative rather than imitative process.

    While computing is applied widely in the production segment of the petroleum industry, its effective application is the primary goal of computing management. Computing technology has changed significantly since the 1950's, when computers first began to influence petroleum technology. The ability to accomplish traditional tasks faster and more economically probably is the most important effect that computing has had on the industry. While speed and lower cost are important, are they enough? Can computing change the basic functions of the industry? When new computing technology is introduced improperly, it can clash with traditional petroleum technology. This paper examines the role of management in merging these technologies

    Pilotto, Alberto; Boi, Raffaella; Petermans, Jean

    2018-03-13

    Recently, the interest of industry, government agencies and healthcare professionals in technology for aging people has increased. The challenge is whether technology may play a role in enhancing independence and quality of life and in reducing individual and societal costs of caring. Information and communication technologies, i.e. tools aimed at communicating and informing, assistive technologies designed to maintain older peoples' independence and increasing safety, and human-computer interaction technologies for supporting older people with motility and cognitive impairments as humanoid robots, exoskeletons, rehabilitation robots, service robots and companion-type are interdisciplinary topics both in research and in clinical practice. The most promising clinical applications of technologies are housing and safety to guarantee older people remaining in their own homes and communities, mobility and rehabilitation to improve mobility and gait and communication and quality of life by reducing isolation, improve management of medications and transportation. Many factors impair a broad use of technology in older age, including psychosocial and ethical issues, costs and fear of losing human interaction. A substantial lack of appropriate clinical trials to establish the clinical role of technologies to improve physical or cognitive performances and/or quality of life of subjects and their caregivers may suggest that the classical biomedical research model may not be the optimal choice to evaluate technologies in older people. In conclusion, successful technology development requires a great effort in interdisciplinary collaboration to integrate technologies into the existing health and social service systems with the aim to fit into the older adults' everyday life.

    This study analyzes how a group of ‘mediators’ in a large, multinational company adapted a computer-mediated communication technology (a ‘virtual workspace’) to the organizational context (and vice versa) by modifying features of the technology, providing ongoing support for users, and promoting...... appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology will be established and used in an organization. However, this study also indicates that the process...... of technology-use mediation is more complex and indeterminate than earlier literature suggests. In particular, we want to draw attention to the fact that advanced computer-mediated communication technologies are equivocal and that technology-use mediation consequently requires ongoing sensemaking (Weick 1995)....

    Technology is not an end in itself, but a means to an end for human existence. If it does not serve this purpose it must be adapted or changed. Criticism of technology is necessary in view of the various positive and negative consequences of technology, it must however be based on judgement and sense of responsibility. It is however often claimed that technology and industry are the tools of the evil and that the technical intelligentsia do not feel responsible for psychological, social and political consequences of their doing. By contributions of several authors and of different periods this book elucidates the often grotesque contradictions between demagogic accusation of technology and the reality of technology; this book presents principal considerations on an acceptable assessment of technology.

    Technologies using renewable energy sources are receiving increasing interest from both public authorities and power producing companies, mainly because of the environmental advantages they procure in comparison with conventional energy sources. These technologies can be substitution for conventional energy sources and limit damage to the environment. Furthermore, several of the renewable energy technologies satisfy an increasing political goal of self-sufficiency within energy production. The subject of this thesis is promotion of renewable technologies. The primary goal is to increase understanding on how technological development takes place, and establish a theoretical framework that can assist in the construction of policy strategies including instruments for promotion of renewable energy technologies. Technological development is analysed by through quantitative and qualitative methods. (BA)

    Technology empowerment” means that innovation is increasingly accessible to ordinary people of limited means. As powerful technologies become more affordable and accessible, and as people are increasingly connected around the world, ordinary people are empowered to participate in the process of innovation and share the fruits of collaborative innovation. This annotated briefing describes technology empowerment and focuses on how empowerment may create challenges to U.S. national security. U.S. defense research as a share of global innovation has dwindled in recent years. With technology empowerment, the role of U.S. defense research is likely to shrink even further while technology empowerment will continue to increase the speed of innovation. To avoid falling too far behind potential technology threats to U.S. national security, U.S. national security institutions will need to adopt many of the tools of technology empowerment.

    This grant supported the effort to characterize the problem domain of the Earth Science Technology Office's Computational Technologies Project, to engage the Beowulf Cluster Computing Community as well as the High Performance Computing Research Community so that we can predict the applicability of said technologies to the scientific community represented by the CT project and formulate long term strategies to provide the computational resources necessary to attain the anticipated scientific objectives of the CT project. Specifically, the goal of the evaluation effort is to use the information gathered over the course of the Round-3 investigations to quantify the trends in scientific expectations, the algorithmic requirements and capabilities of high-performance computers to satisfy this anticipated need.

  11. Technology transfer - the role of AEA Technology

    International Nuclear Information System (INIS)

    Hughes, A.E.; Bullough, R.; Mason, J.P.

    1989-01-01

    This paper concentrates mostly on examples of spin offs which have arisen from the more basic research carried out by the AEA. However, it should not be inferred from this that the only examples of successful technology transfer by the AEA are of a similar, often unforeseen nature. The most outstanding example of technology transfer by the AEA must surely be that achieved through the applied research which has enabled the establishment of a successful civil nuclear power programme in the UK. The natural transfer of technology here, achieved by virtue of the unique bridging position of the AEA with respect to universities and the nuclear industry, means that its success can easily be overlooked; to do so would be a mistake. However, by including spin off examples, we hope to illustrate how the AEA has also succeeded in bridging to more difficult areas where the special relationship which it shares with the nuclear industry is absent.

    2017-01-01

    Technology has not only become an integral part of people’s lives but also of people’s everyday struggles. Struggles with technology are complex in nature; we tend to not only struggle with their basic functions but also with how they make us feel. During the course of our life we tend to master...... and struggle with technology in different ways. This struggle has been studied in relation to media literacy (Livingstone, 2004), to domestication theory (Silverstone et al. 1992), or in everyday life (Bakardjieva, 2005). This work enhances these lines of studies by exploring everyday struggles with technology...... from a life stage (Erikson, 1959) point of view. In particular, we explore what are common struggles people have with technology and what are distinct struggles in relation to life stages. In conclusion, we will present our findings by outlining what we call ‘technological biographies’. Those...

    Davis, K.J.; Russell, D.J.

    1993-01-01

    The Superfund Amendments and Reauthorization Act (SARA) presents a legislative mandate to select effective and long-term remediation options. SARA has spurred the development of innovative technologies and other remedial alternatives that can be applied to the diverse contaminated media at hazardous waste sites. Even though many treatment technologies have been investigated for use at hazardous waste sites, only a few have been used successfully. Soil vapor extraction and soil composting have achieved cleanup goals at sites with soils contaminated with solvents, aromatic hydrocarbons and petroleum derivatives. With the increased use of innovative on-site technologies, the integration of multiple technologies to remediate sites with complex contaminants becomes a viable and cost-effective remedial alternative. Soil vapor extraction and composting have been applied successfully as individual technologies at hazardous waste sites. An integration of these two technologies also has been used to remediate a complex contaminated site

    As a response to climate change and the desire to gain independence from imported fossil fuels, there is a pressure to increase the proportion of electricity from renewable sources which is one of the reasons why electricity grids are currently being turned into Smart Grids. In this paper, we focus...... on private consumers’ acceptance of having Smart Grid technology installed in their home. We analyse acceptance in a combined framework of the Technology Acceptance Model and the Norm Activation Model. We propose that individuals are only likely to accept Smart Grid technology if they assess usefulness...... in terms of a positive impact for society and the environment. Therefore, we expect that Smart Grid technology acceptance can be better explained when the well-known technology acceptance parameters included in the Technology Acceptance Model are supplemented by moral norms as suggested by the Norm...

    2016-08-01

    Several emerging or disruptive technologies can be identified that might, at some point in the future, displace established laboratory medicine technologies and practices. These include increased automation in the form of robots, 3-D printing, technology convergence (e.g., plug-in glucose meters for smart phones), new point-of-care technologies (e.g., contact lenses with sensors, digital and wireless enabled pregnancy tests) and testing locations (e.g., Retail Health Clinics, new at-home testing formats), new types of specimens (e.g., cell free DNA), big biology/data (e.g., million genome projects), and new regulations (e.g., for laboratory developed tests). In addition, there are many emerging technologies (e.g., planar arrays, mass spectrometry) that might find even broader application in the future and therefore also disrupt current practice. One interesting source of disruptive technology may prove to be the Qualcomm Tricorder XPrize, currently in its final stages.

    Sommer, Jannek K.; Knudsen, Gry Høngsmark

    In this poster we address consumption of technology from the perspective of failure. A large body of studies of consumption of technology have focused on consumer acceptance (Kozinets, 2008). These studies have identified particular narratives about social and economic progress, and pleasure...... (Kozinets, 2008) as drivers of consumer acceptance of new technology. Similarly, Giesler (2008) has conceptualized consumer acceptance of technology as a form of marketplace drama, in which market ideologies are negotiated between consumers and media discourses. We suggest to study discourses around failed...... technology products to explore the negotiation of the familiar and alien that makes consumers reject or embrace a new technology. Thus, this particular project sets out to analyze consumer discourses surrounding the Google Glass video “How it Feels [through Google Glass]” on YouTube, because we want...

  2. TECHNOLOGY MANAGEMENT PROCESS FRAMEWORK

    Directory of Open Access Journals (Sweden)

    Ikura Yamamoto

    2012-02-01

    Full Text Available The effective management of technology as a source of competitive advantage is of vital importance for many organizations. It is necessary to understand, communicate and integrate technology strategy with marketing, financial, operations and human resource strategies. This is of particular importance when one considers the increasing cost, pace and complexity of technology developments, combined with shortening product life cycles. A five process model provides a framework within which technology management activities can be understood: identification, selection, acquisition, exploitation and protection. Based on this model, a technology management assessment procedure has been developed, using an ``action research’’ approach. This paper presents an industrial case study describing the first full application of the procedure within a high-volume manufacturing business. The impact of applying the procedure is assessed in terms of benefits to the participating business, together with improvements to the assessment procedure itself, in the context of the action research framework.

    2011-03-01

    Full Text Available The aim of this study was to identify the factors that influence in configuration of the technological capability of companies in sectors with medium-low technological intensity. To achieve the goal proposed in this article a survey was carried out. Based on the framework developed by Lall (1992 which classifies firms in basic, intermediate and advanced level of technological capability; it was found that the predominant technological capability is intermediate, with 83.7% of respondent companies (plastics companies in Brazil. It is believed that the main contribution of this study is the finding that the dependent variable named “Technological Capability” can be explained at a rate of 65% by six variables: development of new processes; selection of the best equipment supplier; sales of internally developed new technology to third parties; design and manufacture of equipment; study of the work methods and perform inventory control; and improvement of product quality.

    Mizon, G.A.; Bleasdale, P.A.

    1994-01-01

    Nuclear power is firmly established in many developed countries'energy policies and is being adopted by emerging nations as an attractive way of gaining energy self sufficiency. The early users of nuclear power had to develop the technology that they needed, which now, through increasing world wide experience, has been rationalised to meet demanding economic and environmental pressures. These justifiable pressures, can lead to existing suppliers of nuclear services to consider changing to more appropriate technologies and for new suppliers to consider licensing proven technology rather then incurring the cost of developing new alternatives. The transfer of technology, under license, is made more straight forward if the owner conveniently groups appropriate technology into packages. This paper gives examples of 'Technology Packages' and suggests criteria for the specification, selection and contractual requirements to ensure successful licensing

    The most important applications of the radiation technology are the crosslinking of polymers and sterilisation. Although extensive experience about the use of this technology is available and powerful and dependable radiation facilities can be obtained, as yet the radiation technology has not found the acceptance it deserves in the industry. The main reason therefore has to do with how the question of radiation or the term radiation is presented to the industry and among the population. This paper will deal with considerations and ways in which the industrial use of the radiation technology can be expanded. (author)

    Finland has wide experience in applications of various combustion technologies and fuels and in supplying energy to industry and municipalities. Furthermore, combustion hardware and equipment are amongst our most important export products. Above all, fluidized bed boilers, recovery boilers for pulp mills and heavy diesel engines and diesel power plants have achieved excellent success in the world markets. Exports of these products alone have amounted to several billions of Finnish marks of annual sales in recent years. Within modern combustion technology, the objective is to control flue gas emissions as far as possible in the process itself, thus doing away with the need for the separate scrubbing of flue gases. To accomplish this it has been necessary to conduct a large amount of research on the details of the chemistry of combustion emissions and the flows in furnaces and engine cylinders. A host of completely new products are being developed for the combustion technology field. The LIEKKI programme has been particularly interested in so-called combined-cycle processes based on pressurized fluidized bed technology

    2004-03-01

    Nanotechnology is a revolutionary engine that will engender enormous changes in a vast majority of today's industries and markets, while potentially creating whole new industries. The impact of nanotechnology is particularly significant in the electronics industry, which is constantly driven by the need for higher performance, increased functionality, smaller size and lower cost. Nanotechnology can influence many of the hundreds of components that are typically assembled to manufacture modern electronic devices. Motorola manufactures electronics for a wide range of industries and communication products. In this presentation, the typical components of a cellular phone are outlined and technology requirements for future products, the customer benefits, and the potential impact of nanotechnology on many of the components are discussed. Technology needs include reliable materials supply, processes for high volume production, experimental and simulation tools, etc. For example, even routine procedures such as failure characterization may require the development of new tools for investigating nano-scale phenomena. Business needs include the development of an effective, high volume supply chain for nano-materials and devices, disruptive product platforms, and visible performance impact on the end consumer. An equally significant long-term industry need is the availability of science and engineering graduates with a multidisciplinary focus and a deep understanding of the fundamentals of nano-technology, that can harness the technology to create revolutionary products.

  11. Robotics Technology Crosscutting Program. Technology summary

    International Nuclear Information System (INIS)

    1995-06-01

    The Robotics Technology Development Program (RTDP) is a needs-driven effort. A length series of presentations and discussions at DOE sites considered critical to DOE's Environmental Restoration and Waste Management (EM) Programs resulted in a clear understanding of needed robotics applications toward resolving definitive problems at the sites. A detailed analysis of the resulting robotics needs assessment revealed several common threads running through the sites: Tank Waste Retrieval (TWR), Contaminant Analysis Automation (CAA), Mixed Waste Operations (MWO), and Decontamination and Dismantlement (D and D). The RTDP Group also realized that some of the technology development in these four areas had common (Cross Cutting-CC) needs, for example, computer control and sensor interface protocols. Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) process urged an additional organizational breakdown between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). These factors lead to the formation of the fifth application area for Crosscutting and Advanced Technology (CC and AT) development. The RTDP is thus organized around these application areas -- TWR, CAA, MWO, D and D, and CC and AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas

Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) process urged an additional organizational breakdown between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). These factors lead to the formation of the fifth application area for Crosscutting and Advanced Technology (CC and AT) development. The RTDP is thus organized around these application areas -- TWR, CAA, MWO, D and D, and CC and AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas.

  16. Digital Actuator Technology

    Energy Technology Data Exchange (ETDEWEB)

    Ken Thomas; Ted Quinn; Jerry Mauck; Richard Bockhorst

    2014-09-01

    There are significant developments underway in new types of actuators for power plant active components. Many of these make use of digital technology to provide a wide array of benefits in performance of the actuators and in reduced burden to maintain them. These new product offerings have gained considerable acceptance in use in process plants. In addition, they have been used in conventional power generation very successfully. This technology has been proven to deliver the benefits promised and substantiate the claims of improved performance. The nuclear industry has been reluctant to incorporate digital actuator technology into nuclear plant designs due to concerns due to a number of concerns. These could be summarized as cost, regulatory uncertainty, and a certain comfort factor with legacy analog technology. The replacement opportunity for these types of components represents a decision point for whether to invest in more modern technology that would provide superior operational and maintenance benefits. Yet, the application of digital technology has been problematic for the nuclear industry, due to qualification and regulatory issues. With some notable exceptions, the result has been a continuing reluctance to undertake the risks and uncertainties of implementing digital actuator technology when replacement opportunities present themselves. Rather, utilities would typically prefer to accept the performance limitations of the legacy analog actuator technologies to avoid impacts to project costs and schedules. The purpose of this report is to demonstrate that the benefits of digital actuator technology can be significant in terms of plant performance and that it is worthwhile to address the barriers currently holding back the widespread development and use of this technology. It addresses two important objectives in pursuit of the beneficial use of digital actuator technology for nuclear power plants: 1. To demonstrate the benefits of digital actuator

    1998-01-01

    This NASA Strategic Plan describes an ambitious, exciting vision for the Agency across all its Strategic Enterprises that addresses a series of fundamental questions of science and research. This vision is so challenging that it literally depends on the success of an aggressive, cutting-edge advanced technology development program. The objective of this plan is to describe the NASA-wide technology program in a manner that provides not only the content of ongoing and planned activities, but also the rationale and justification for these activities in the context of NASA's future needs. The scope of this plan is Agencywide, and it includes technology investments to support all major space and aeronautics program areas, but particular emphasis is placed on longer term strategic technology efforts that will have broad impact across the spectrum of NASA activities and perhaps beyond. Our goal is to broaden the understanding of NASA technology programs and to encourage greater participation from outside the Agency. By relating technology goals to anticipated mission needs, we hope to stimulate additional innovative approaches to technology challenges and promote more cooperative programs with partners outside NASA who share common goals. We also believe that this will increase the transfer of NASA-sponsored technology into nonaerospace applications, resulting in an even greater return on the investment in NASA.

    2018-04-01

    Full Text Available Climate change and accelerated urbanization have posed severe challenges to urban development, resulting in a growing series of climate and environmental problems that have a significant impact on industrial production and urban life. In a developing country such as China, more than 57% of the population lives in urban areas. It is vital for these cities to adapt to climate-induced risks. A better understanding of how to improve adaptive capacity could enhance the ability to achieve a desirable state when the city experiences stress. This paper used an integrated approach for evaluating the urban adaptive capacity to climate change. It developed the evaluation index system of urban adaptive capacity (UAC based on the driver–pressure–state–impact–response model (DPSIR, and adopted grey relational analysis (GRA and the entropy method to analyze the level of UAC in Changsha, the capital city of Hunan Province, from 2006 to 2015. The results revealed that the UAC of Changsha showed a significant increase from 2006 to 2015. Among the five first-grade indicators, the response dimension had the greatest influence on the improvement of UAC. The study may provide suggestions for adaptive capacity building and sustainable development in other urban areas.

First, the technology formed the basis of rapid expansion of great ideas promoted by globalization. Undeniable progress in the field of technology and science, has conferred to the man extraordinary powers that have been used most often to the detriment of his spiritual progress. We must not deny that science and technology have brought many benefits to human, and he could expand the knowledge horizon upon the world in which he lives, exploiting information acquired and share them with others. Science and technology must become for postmodern man ways of talk and communion between human and divinity, all to the praise of God and the perfection of the creature.

    KfK participates to the Fusion Technology Programme of the European Community. Most of the work in progress addresses the Next European Torus (NET) and the long term technology aspects as defined in the 82/86 programme. A minor part serves to preparation of future contributions and to design studies on fusion concepts in a wider perspective. The Fusion Technology Programme of Euratom covers mainly aspects of nuclear engineering. Plasma engineering, heating, refueling and vacuum technology are at present part of the Physics Programme. In view of NET, integration of the different areas of work will be mandatory. KfK is therefore prepared to address technical aspects beyond the actual scope of the physics experiments. The technology tasks are reported project wise under title and code of the Euratom programme. Most of the projects described here are shared with other European fusion laboratories as indicated in the table annexed to this report. (orig./GG)

  17. Technology and climate change

    International Nuclear Information System (INIS)

    Morrison, R.; Layzell, D.; McLean, G.

    2001-01-01

    This paper provides a context for assessing the needs for technologies to reduce the concentration of GHG in the atmosphere. It looks at sources, sinks and trends for GHG, in the world at large and in Canada, and at efforts to develop new technologies to achieve the goals of climate change policy. Technology development is one of many approaches to reducing emissions and absorbing GHG from the atmosphere. New technologies will be more successful if they can also achieve non-climate goals, such as better air quality or reduced soil erosion. This paper examines sectors where new technology may be most needed. In general these will be areas where emissions are large, or growing rapidly, or both. It focuses on transport, electricity and biomass as sectors of interest, both because of their potential for contributing to climate change policy goals within Canada, and also because of the author's own research interests.

    1977-01-01

    This article presents the similarities in the technology required for high energy accelerators and tokamak fusion devices. The tokamak devices and R and D programs described in the text represent only a fraction of the total fusion program. The technological barriers to producing successful, economical tokamak fusion power plants are as many as the plasma physics problems to be overcome. With the present emphasis on energy problems in this country and elsewhere, it is very likely that fusion technology related R and D programs will vigorously continue; and since high energy accelerator technology has so much in common with fusion technology, more scientists from the accelerator community are likely to be attracted to fusion problems

    This study identifies and technically assesses foreign decontamination and decommissioning (D and D) technology developments that may represent significant improvements over D and D technology currently available or under development in the United States. Technology need areas for nuclear power reactor decommissioning operations were identified and prioritized using the results of past light water reactor (LWR) decommissioning studies to quantitatively evaluate the potential for reducing cost and decommissioning worker radiation dose for each major decommissioning activity. Based on these identified needs, current foreign D and D technologies of potential interest to the US were identified through personal contacts and the collection and review of an extensive body of D and D literature. These technologies were then assessed qualitatively to evaluate their uniqueness, potential for a significant reduction in D and D costs and/or worker radiation dose, development status, and other factors affecting their value and applicability to US needs. 4 refs

  4. Enabling cleanup technology transfer

    International Nuclear Information System (INIS)

    Ditmars, J. D.

    2002-01-01

    Technology transfer in the environmental restoration, or cleanup, area has been challenging. While there is little doubt that innovative technologies are needed to reduce the times, risks, and costs associated with the cleanup of federal sites, particularly those of the Departments of Energy (DOE) and Defense, the use of such technologies in actual cleanups has been relatively limited. There are, of course, many reasons why technologies do not reach the implementation phase or do not get transferred from developing entities to the user community. For example, many past cleanup contracts provided few incentives for performance that would compel a contractor to seek improvement via technology applications. While performance-based contracts are becoming more common, they alone will not drive increased technology applications. This paper focuses on some applications of cleanup methodologies and technologies that have been successful and are illustrative of a more general principle. The principle is at once obvious and not widely practiced. It is that, with few exceptions, innovative cleanup technologies are rarely implemented successfully alone but rather are implemented in the context of enabling processes and methodologies. And, since cleanup is conducted in a regulatory environment, the stage is better set for technology transfer when the context includes substantive interactions with the relevant stakeholders. Examples of this principle are drawn from Argonne National Laboratory's experiences in Adaptive Sampling and Analysis Programs (ASAPs), Precise Excavation, and the DOE Technology Connection (TechCon) Program. The lessons learned may be applicable to the continuing challenges posed by the cleanup and long-term stewardship of radioactive contaminants and unexploded ordnance (UXO) at federal sites

    1985-01-01

    In the United States, the advanced technologies have been applied to uranium enrichment as a means by which it can be assured that nuclear fuel cost will remain competitive in the future. The United States is strongly committed to the development of advanced enrichment technology, and has brought both advanced gas centrifuge (AGC) and atomic vapor laser isotope separation (AVLIS) programs to a point of significant technical refinement. The ability to deploy advanced technologies is the basis for the confidence in competitive future price. Unfortunately, the development of advanced technologies is capital intensive. The year 1985 is the key year for advanced technology development in the United States, since the decision on the primary enrichment technology for the future, AGC or AVLIS, will be made shortly. The background on the technology selection process, the highlights of AGC and AVLIS programs and the way to proceed after the process selection are described. The key objective is to maximize the sales volume and minimize the operating cost. This will help the utilities in other countries supply low cost energy on a reliable, long term basis. (Kako, I.)

    This paper will talk about the technologies that have been emerging over the 25 years since the Human Vision and Electronic Imaging conference began that the conference has been a part of, and that have been a part of the conference, and will look at those technologies that are emerging today, such as social networks, haptic technologies, and still emerging imaging technologies, and what we might look at for the future.Twenty-five years is a long time, and it is not without difficulty that we remember what was emerging in the late 1980s. Yet to be developed: The first commercial digital still camera was not yet on the market, although there were hand held electronic cameras. Personal computers were not displaying standardized images, and image quality was not something that could be talked about in a standardized fashion, if only because image compression algorithms were not standardized yet for several years hence. Even further away were any standards for movie compression standards, there was no personal computer even on the horizon which could display them. What became an emergent technology and filled many sessions later, image comparison and search, was not possible, nor the current emerging technology of social networks- the world wide web was still several years away. Printer technology was still devising dithers and image size manipulations which would consume many years, as would scanning technology, and image quality for both was a major issue for dithers and Fourier noise.From these humble beginnings to the current moves that are changing computing and the meaning of both electronic devices and human interaction with them, we will see a course through the changing technology that holds some features constant for many years, while others come and go.

  14. COPPER CABLE RECYCLING TECHNOLOGY

    International Nuclear Information System (INIS)

    Chelsea Hubbard

    2001-01-01

    The United States Department of Energy (DOE) continually seeks safer and more cost-effective technologies for use in deactivation and decommissioning (D and D) of nuclear facilities. The Deactivation and Decommissioning Focus Area (DDFA) of the DOE's Office of Science and Technology (OST) sponsors large-scale demonstration and deployment projects (LSDDPs). At these LSDDPs, developers and vendors of improved or innovative technologies showcase products that are potentially beneficial to the DOE's projects and to others in the D and D community. Benefits sought include decreased health and safety risks to personnel and the environment, increased productivity, and decreased costs of operation. The Idaho National Engineering and Environmental Laboratory (INEEL) generated a list of statements defining specific needs and problems where improved technology could be incorporated into ongoing D and D tasks. One such need is to reduce the volume of waste copper wire and cable generated by D and D. Deactivation and decommissioning activities of nuclear facilities generates hundreds of tons of contaminated copper cable, which are sent to radioactive waste disposal sites. The Copper Cable Recycling Technology separates the clean copper from contaminated insulation and dust materials in these cables. The recovered copper can then be reclaimed and, more importantly, landfill disposal volumes can be reduced. The existing baseline technology for disposing radioactively contaminated cables is to package the cables in wooden storage boxes and dispose of the cables in radioactive waste disposal sites. The Copper Cable Recycling Technology is applicable to facility decommissioning projects at many Department of Energy (DOE) nuclear facilities and commercial nuclear power plants undergoing decommissioning activities. The INEEL Copper Cable Recycling Technology Demonstration investigated the effectiveness and efficiency to recycle 13.5 tons of copper cable. To determine the effectiveness

    This is the third in a series of columns exploring health information technology (HIT) in the neonatal intensive care unit (NICU). The first column provided background information on the implementation of information technology throughout the health care delivery system, as well as the requisite informatics competencies needed for nurses to fully engage in the digital era of health care. The second column focused on information and resources to master basic computer competencies described by the TIGER initiative (Technology Informatics Guiding Education Reform) as learning about computers, computer networks, and the transfer of data.1 This column will provide additional information related to basic computer competencies, focusing on communication and collaboration technologies. Computers and the Internet have transformed the way we communicate and collaborate. Electronic communication is the ability to exchange information through the use of computer equipment and software.2 Broadly defined, any technology that facilitates linking one or more individuals together is a collaborative tool. Collaboration using technology encompasses an extensive range of applications that enable groups of individuals to work together including e-mail, instant messaging (IM ), and several web applications collectively referred to as Web 2.0 technologies. The term Web 2.0 refers to web applications where users interact and collaborate with each other in a collective exchange of ideas generating content in a virtual community. Examples of Web 2.0 technologies include social networking sites, blogs, wikis, video sharing sites, and mashups. Many organizations are developing collaborative strategies and tools for employees to connect and interact using web-based social media technologies.3.
