Objectives : The purpose of this study on the oral health behavior of foreign workers and dental care in the community is to identify actual oral health conditions of immigrated labors, to promote their oral health and to gather basic data providing them with proper oral health services Methods : Based on previous studies, The researchers wrote their own surveys in English, in Vietnamnese, in Tagalogue, in Thai. Making questions on the paper to 114 foreign workers in Pocheon, Gyeonggi-do were surveyed. Using the program SPSS 17.0 for Windows, the collected data were analyzed. The frequency analysis, the chi-square analysis and the correlation analysis was performed to recognize their relevance between the oral health status and the actual oral care and the subjective perception of oral health. Results : General characteristics of the foreign workers is the overwhelming majority of male demographic 78.9%. By age, 20-29 years of age accounted for 50%, and duration of stay in the city is less than 3-5 years to 68.4%, It was most common. The percentage going to the dentist when teeth hurt is although 56 percent. But the ratio to endure the pain without going to the dentist, was 44%. The main reason to not go to the dentist was the time 55.2% and cost 11.9%. A mere 9.6% of respondents knew about the free dental care and used. 67.5% of them was not aware of the free dental care agency, 59.6% were keen to use the free care. However, 40.4% did not want a free dental care because they did not have the time(26.3%), the distance is far away(3.5%), and difficulties in communication(3.5%) and the other(66.7%). Conclusions : The major percentage of the other reason(66.7%) why they did not want to go to free dental service, must be specifically identified. For the activation of free dental services, the active support of central and local governments is needed. By focusing on health-related departments of the University in the community, it is necessary to operate the program of the oral health care for foreign workers.

To investigate an effect of Gam-Roa tea on the free radical or alcohol detoxicating enzyme activities, the rats got a drink at the Gam-Roa tea instead of water for 3 months, and then the animals were sacrificed and obtained the following findings. The animals receiving Gam-Roa tea showed a decreasing tendency of hepatic xanthine oxithine oxidase activity and significantly incresed content of cytochrome P-450 compared with the control. Furthermore, hepatic superoxide dismutase and glutathione S-transferase activities were also more increased in rats received Gam-Roa tea than in the control group, those receiving water. On the other hand, alcohol or aldehyde dehydrogenase activities were more increased in rats receiving Gam-Roa tea than the control. In conclusion, it is likely that the liver of rats receiving Gam-Roa tea may have the oxygen free radical or alcohol detoxication potential.

To evaluate the influence of hepatic oxygen free radical systems on liver injury by topical p-phenylenediamine (PPD) application on rat skin, PPD (25 mg/16.5 $\textrm{cm}^2$) was topically applied to the abdominal region 5 times every other day and sacrificed. By PPD treatment, increasing rate of liver weight/body weight (%), serum activities of alanine aminotransferase and aspartate aminotransferase and decreasing rate of microsomal glucose-6-phosphatase activity were higher in the rats fed tungstate supplemented diet than those fed a standard diet. These findings indicate that group fed tungstate supplemented diet have more severe liver injury compared with group fed standard diet on topical PPD application. However, the activities of oxygen free radical generating enzymes such as xanthine oxidase (XO) and cytochrome P450 dependent aniline hydroxylase and those of oxygen free radical scavenging enzymes were not found to be different between these two animal groups. In the present study, a novel monitoring method to detect the generating of oxygen free radicals in liver extract was devised. Throughout this method, the oxidized PPD produced by oxygen free radicals was determined colorimetrically. The increasing rate of PPD oxidation by liver homogenate was higher in tungstate fed animals than in standard diet fed ones. Among the fractionations of liver extract, the mitochondrial and postmitochondrial fractions in the liver extract of tungstate fed animals led to a higher availability of PPD oxidation by PPD treatment compared with standard diet fed ones. In conclusion, these results suggest that an enhanced liver injury in tungstate fed animals treated with PPD may be due to oxygen free radicals produced in other systems except oxygen free radicals generating from cytosolic XO system. Especially, oxidative availability by PPD can be used for oxygen free radical detection in some tissue.

Background: In 2013, legislation in Vietnam regulated smoking in public areas. Included was a ban on indoor smoking at universities. Objective: Since awareness and attitude are moderators of the effectiveness of smoke-free policy, ou aim was to assess changes in students' knowledge and attitude tosecond hand smoke (SHS) and awareness and support of smoke-free legislation at four Vietnamese universities, one year after legislative changes. Methods: A two-phase cross sectional study of undergraduate students using self-administered questionnaires (based on the Global Adult Tobacco Survey and the Thrasher survey) was conducted at the introduction of the legislation and one year thereafter. Results: One-year post legislation there were significant increases in knowledge of smoke-free legislation and awareness of universities as smoke-free environments. There was a significant increase in knowledge of harmful effects of SHS on diseases such as examples in the heart and lung, including lung cancer, and miscarriage. Students expressed strong support of smoke-free environments in universities, hospitals, schools, workplaces, public transport, libraries, cinemas and theatres; support was also increased post legislation. Changes were seen in attitude to SHS, and rights of non-smokers and smokers. Conclusions: Positive changes have occurred in knowledge and attitude toward smoke-free environments and SHS in universities since enactment of Vietnamese tobacco control legislation.

The disinfection effect of free residual chlorine and monochloramine on biofilm communities were investigated by CLPP (community level physiology profile) using Biolog GN plates. Low concentration of disinfectant, $0.5\;mg/\iota$ free chlorine and $1.0\;mg/\iota$ monochloramine, stimulated the growth of bacteria rather than disinfection. Bacterial concentrations were decreased at more than $1.0\;mg/\iota$ of disinfectants. CLPP was different with the type and concentration of disinfectant and sampling time. Common and different carbon sources were actively used with similar bacterial concentration in free chlorine and monochloramine. This represents the differences of bacterial communities with tap water contact times and disinfectant.

To meet the increasing demands of specific pathogen free (SPF) minipigs in biomedical researches, 8 pregnant Chinese Wuzhishan minipigs (WZSP) sows with clear background were chosen to obtain SPF WZSP by hysterectomy. At $111{\pm}days2$ of the pregnancy, piglets were aseptically taken out from the sows and artificially suckled for 40 to 45 days in the positive isolators. Then, the piglets defined as F0 were transferred to barrier environment and fed with standard feeds. The original SPF colony was formed for breeding by selected piglets from F0 group of 6-8 months old. Biological characteristics of SPF WZSP were collected and further compared to those of conventional (CV) WZSP, including growth performance, reproductive performance, hematology and blood biochemistry, and major pathogens detection. As a result, 61 F0 piglets were obtained from 8 candidate sows, and 55 out of them survived. After strictly selection, 35 F0 piglets were used to form the original SPF colony, which produced 14 litters of SPF piglets defined as F1. Piglet survival rates, growth performance, and reproductive performance of SPF WZSP were similar to CV WZSP. Some hematology and blood biochemistry parameters showed significant differences between SPF and CV WZSP. Eighteen kinds of pathogens were identified to be free in F0 and F1 SPF colony by repeated pathogen detections. In conclusion, we established a satisfied SPF WZSP colony maintaining original characteristics, free of controlled diseases, and being proved to be a suitable laboratory animal.

Purpose: This study examined the influence of the consumption values on the attitudes and purchase intentions of consumers towards gluten-free products and compared consumption values, attitudes and purchase intentions according to the degree of health consciousness of the consumer. Methods: The data was collected from July 20, 2016 to August 2, 2016 through a questionnaire survey from three hundred and six consumers who had knowledge of gluten-free products. The data was analyzed by factor analysis, reliability analysis, multiple regression analysis, and an independent sample t-test using the SPSS program. Results: The regression results showed that the exploratory value (p<0.01) had a negative influence on the attitudes, and the functional value (p<0.001) and emotional value (p<0.001) had a positive influence on the consumers' attitudes. In addition, the attitudes (p<0.001) toward gluten-free products had a positive influence on the purchase intentions. Finally, the high health consciousness group answered with a significantly higher score on the consumption values, attitudes and purchase intentions than the lower group. Conclusion: These results highlight the causal relationship among consumption values, attitudes, and purchase intentions of consumers towards gluten-free products, and can provide a basic understanding of gluten free products regarding both marketing strategy and consumers' needs. The potential implications for gluten-free products manufacturers, limitations and future research directions are also discussed.
