Purpose: To describe the prevalence, epidemiological characteristics, and related factors of diabetes mellitus in school personnel. 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.

Purpose ： To describe epidemiological characteristics and related factors in school personnel with hypertension. Method ： 5,384 school personnel (2,638 males and 2,746 females) received physical examination at the Seoul School Health Center in 2002. blood pressure(BP) was classified by JNC 7th report. Normal BP is systolic BP <120 and diastolic BP<80, prehypertension BP is 120-139 or 80-89mmHg, stage 1 hypertension BP is 140-159 or 90-99, and stage 2 hypertension >=160 or >=100 mmHg. each group was evaluated by gender. We used multiple regression and logistic regression. Results ： Normotension was 20.13% in males and 48.65% in female, prehypertension 43.4% in males and 38.06% in females, stage 1 hypertension 26.38% in males and 10.99% in females, stage2 hypertension 9.59% in males and 3.2% in females. the older age group had higher distribution of stage 1 hypertension and stage 2 hypertension. The means and abnormal rates of BMI, blood sugar, total cholesterol, GOT, GPT, and GTP was higher when their blood pressure was higher. However, an alcohol habit among lifestyle factors had an inverse effect. Higher Bp was correlated to a higher BMI, FBS, and cholesterol-like dose response. In stage 1 hypertension, the related factors of hypertension for males were BMI, amount of cigarettes smoked, exercise, blood sugar, total cholesterol, and GTP. In stage 1 hypertension, age, BMI, exercise, blood sugar, total cholesterol were related factors in female. In stage 2 hypertension, age and smoking were related factors in male, and age, BMI, and cholesterol in female. Conclusions ： It is possible to intervene in all related factors of hypertension except age through life-style modification and appropriate medical management. Active health promotion is needed in School personnel.

This study analyzed the factors of stress perception and their patterns depending on the high school students from different types of high school, which include academic high schools and vocational high schools. The data reflected the degree of stress perception according to several factors, which are considered to be related to stress perception, and the study analyzed how differently these factors affected students in each school type. The subjects were 29,380 students from the 14th Korea Youth Health Behavior Survey who meet the purpose of this study. The factors related to stress perception were classified into general characteristics, health behavior characteristics, and health status characteristics. The factors of the study were compared in each group and between the groups. In both school types, stress perception was associated with a number of common factors and some group specific factors. The common main factors related to stress perception were depressive experience, subjective recognition of their health status, subjective recognition of sleep satisfaction, and gender. However, the pattern in which each factor was related to stress perception differed according to the school types. Therefore, efforts should be made to reflect the characteristics of each school type while considering the common factors related to stress perception when making policies for managing high school students' stress.

The 96 elementary school teachers' the degrees of understandings about the characteristics of the currents according to the connection methods of batteries in simple electric circuits were investigated. In this study, the concepts on the characteristics of currents according to the connection methods of batteries were divided 'the learned concepts' and 'the differentiated concepts'. The characteristics of the currents in the region of the larger resistance of load than the internal resistance of a battery were called the learned concepts, they are taught in the science curriculum. While the characteristics of the currents in the region of the smaller resistance of load than the internal resistance of a battery were called the differentiated concepts, they are not exposed clearly in the science curriculum. The results obtained in this study are as follows: The average score related to the learned concepts was relatively high, while the degree of the teachers' cognitions of the internal resistance of a battery and the resistance of wires were low. Also the average score related to the differentiated concepts was very low because it seems so new to the elementary school teachers. It strongly suggests that the elementary school teachers did not understand meaningfully the characteristics of the currents related to the connections of batteries on the ground of the cognitions of the internal resistances of batteries and the resistances of loads in simple electric circuits. Hence, they might experience difficulties due to the problems occurred in relation to the connections of batteries in the elementary school science lessons.
