Objectives: The purpose of this study was to examine factors influencing the mental health of high school students in relation to sociodemographic variables, family function, self-esteem, social support, and self-identity. Methods: The survey was carried out on a convenience sample of 332 high school students. Data analysis procedure included stepwise regression using mental health as the dependent variable, and sociodemographics, family function, self-esteem, social support, and self-identity, as independent variables. Results: Stepwise multiple regression revealed that the factors such as self-esteem(${\beta}=0.422$, p<0.001), self-identity(${\beta}=0.166$, p<0.001), and sex(${\beta}=-0.165$, p<0.001) turned out to be significant affecting factors. Twenty seven percent of varience in mental health was explained by these factors(22% of varience by self-esteem). Conclusion: Self-esteem was turned out to be the most important effective factor of mental health in high school students. These results suggest that it is important for high school students to promote their self-esteem to keep their good mental health.

Hepatocellular carcinoma is a common disorder worldwide which ranks 5th and 7th most common cancer among men and women. In recent years, different incidence trends have been observed in various regions, but the reasons are not completely understood. However, due to the great public efforts in HCC prevention and alternation of lifestyle, the roles of some well documented risk factors played in hepatocarcinogenesis might have changed. This paper summarizes both the environmental and host related risk factors of hepatocellular carcinoma including well established risk factors such as hepatitis virus infection, aflatoxin and alcohol, as well as possible risk factors such as coffee drinking and other dietary agents.

Method：5,384 school personnel (2,638 males 2,746 females) received physical examinations at the Seoul School Health Center in 2002. Using the American Diabetes Association criteria, and fasting blood sugar(FBS) was classified as normal at 110>=FBS, borderline 111-125, and the diabetes group 126<=FBS. Related factors of each group were evaluated by gender. Results： In the diabetes group, there were 4.74% males and 0.8% females, and the borderline group was 6.37% males and 2.22% females. The older age group gad a higher distribution in both males and females in the diabetes group. In the diabetes group, the mean and abnormal rate of BMI, systolic hypertension, diastolic hypertension, total cholesterol, GOT, GPT, and GTP were higher than in the normal group. In life style factor, the diabetes group gad a higher distribution of meat eating and smoking more than 20 years than the normal group. The effect of FBS on BMI, BP(blood pressure), total cholesterol, GOT, GPT, and GTP were investigated after controlling for confounding variables. In the borderline and diabetes group, the mean of BMI, BP, total cholesterol, GOT, GPT, and GTP was higher in dose-response effect. In the logistic multiple regression, the related factors of the diabetes group were hypertension and abnormal GTP in males, and abnormal total cholesterol and GTP in females. In the borderline group, the related factors were meat eating, hypertension, and high GOT in males and the older age group, and hypertension, total cholesterol, and abnormal GTP in females. Conclusions: It is possible to manage all related factors of diabetes mellitus except for age. An appropriate program for health promotion is necessary.

Exposure factors based on the Korean population are required for making appropriate risk assessment. It is expected that handbooks for exposure factors will be applied in many fields, as well as by health department risk assessors. The present article describes the development of an exposure factors handbook that specifically focuses on human activities in situations involving the possible risk of exposure to environmental contaminants. We define majour exposure factors that represent behavioral patterns for risk assessment, including time spent on routine activities, in different places, on using transportation, and engaged in activities related to water contact including swimming, bathing and washing. Duration of residence and employment are also defined. National survey data were used to identify recommended levels of exposure factors in terms of time spent on routine activities and period of residence and employment. An online survey was conducted with 2073 subjects who were selected using a stratified random sampling method in order to develop a list of exposure factors for the time spent in different places and in performing water-related activities. We provide the statistical distribution of the variables, and report reference levels of average exposure based on the reliable data in our exposure factors handbook.

The purpose of this study was to investigate the related factors to nutritional supplements intake of elementary school student aged 7 to 12 years in Incheon area. The subjects were 631 mothers of elementary school students and cross-sectional study was conducted by a self-administered questionnaire. In view of the relation with general circumstances, taking nutritional supplements was shown to be significantly associated with general and socio-demographic factors such as father's job, mothers concern about children's academic record, family's monthly income and food cost, and the experience of other family members' taking nutritional supplement. In view of the relation with anthropometric and health-related factors, taking nutritional supplement was associated with elementary school student' weight obesity index, mothers evaluation of children's height and weight mother's concern about health and growth of children, and ,disease of children. In view of the dietary behavior-related factors, taking nutritional supplements was associated with skipping breakfast, food habits, and mothers beliefs and attitude about nutrition and nutritional supplements. However, it was shown that mothers nutritional knowledge did not affect taking nutritional supplements. Therefore, it may be suggested that general and socio-demographic factors, anthropometric and health-related factors, dietary behavior-related factors, and mother's nutritional beliefs and attitude are important determinants in children's taking nutritional supplements.
