Handicraft villages play an important role in promoting social and economic development in rural areas as well as Vietnam＇s economy. Nowadays, Vietnam＇s handicrafts have a foothold in the world market, and are exported over 163 countries and territories （Tuan, 2010）. However, the production activities of the handicraft village have a lot of shortcomings, especially the problem of environmental pollution （Chi, 2010）. Therefore, government policy plays a very important role to minimize environmental pollution villages, contributing to improving environmental quality and public health. this paper focuses on： 1）. Current status of state policy environment in handicraft villages shows the achievements and limitations of the policy, from which reviews state policy in environments in handicraft villages （through fieldwork in the handicraft villages）; and 2）. Solution to improve state policy on environmental protection in handicraft villages in Vietnam.

Objective: The aim of the study is to investigate the “new-onset jaundice” incidence, map of causes, approaching method, and risk factors for treatment failure in adult in-patients at a tertiary general hospital as Cho Ray Hospital, Ho Chi Minh City, Viet Nam. Method: Retrospective study was done on 416 jaundice patients administered over 38 continuous days. Laboratory tests investigated were total bilirubin, direct bilirubin, AST, ALT, AST/ALT ratio, GGT, AP, bilirubin and urobilinogen in urine. Jaundice was defined as total bilirubin ≥ 2.5 mg/dL, direct bilirubin jaundice defined as direct bilirubin > 2 mg/dL and D/T percentage > 60%, the severity of AST, ALT evaluated according to Common Terminology Criteria for Adverse Events, AST/ALT ratio, and bilirubin, urobilinogen in urine. Outcome of treatment were classified in two groups: failure (dead or discharge due to worse status) and success. Descriptive statistics and analytic statistics were applied, mono-variable analysis and multinomial logistic regression to find out the independent risk factors for treatment failure. Results: The incidence of “new-onset” jaundice in adult patients was 11 ± 5 person/day. The map of jaundice included 3 phases as pre-heaptic 13.7%, in-hepatic 58.2%, and post-hepatic 22.8%. Pancreatic and biliary tract diseases accounted 17.1%, then cirrhosis 16.3%, liver tumor 14.7%, hepatitis 8.9%, sepsis 8.9%, hematology diseases 7.9%, and cardiac diseases 7.5%. A guide for approaching causes of jaundice basing on 7 parameters as total bilirubin, D/T percentage, severity of ALT, AST/ALT ratio, severity of GGT, and bilirubin and urobilinogen in urine was established. The overall mortality was 7.5% (31/416), sepsis had highest death rate of 37.8% (14/37). Sepsis and AST/ALT ratio > 2 were the two independent risk factors of mortality. Conclusion: At tertiary hospital, jaundice is common sign in adult patient, diverse enormously in many clinical wards. The map of causes of jaundice completed all

Objectives: The study aimed to describe the quality of sleep and explore factors especially Sleep Hygiene Practices associated with sleep quality among pregnant women. Study design: this is a cross-sectional study. Methods: 119 healthy pregnant women in two central hospitals in Vietnam were participated in this study. The Pittsburgh Sleep Quality Index (PSQI) was employed to evaluate sleep quality and the Modified Sleep Hygiene Practices was used to describe sleeping practices among pregnant women. Results: The results showed that while 58.8% pregnant women had quite good sleep quality, 41.2% of pregnant women had mild to moderate quality sleep disturbance. The quality of sleep was better in second trimester, but then getting worst in the third trimester. Multipara experienced worse sleep quality than nullipara. Poor sleep quality had a positive correlation with unhealthy Sleep Hygiene Practices including using an uncomfortable bed (p third trimester as they experience more change in hormone and physiology. Sleep Hygiene Practices should be emphasized in health education for pregnant women.

以毛竹Phyllostachys edulis集成材为研究对象,在不同条件下进行高频热压,通过对竹集成材板坯高频热压过程中芯层温度变化的统计分析,得到了竹集成材高频热压过程中板坯温度的变化规律。结果表明:在试验条件范围内,随着板坯含水率从6%增加到18%,涂胶量从200 g·m-2增加到300 g·m-2,板坯的温度明显升高。升温过程可以分为快速升温和慢速升温2个阶段。在快速升温阶段板坯内的温度随板坯初含水率、涂胶量及加热时间的提高而递增;在慢速升温阶段板坯初含水率及涂胶量对板坯内的温度的影响很小,板坯芯层升温速度随加热时间的增加而减少。通过试验数据分析,得出较优的高频热压胶合工艺条件为:涂胶量300 g·m-2,竹条含水率12%,高频热压时间7 min。
