The purpose of this study is to investigate the misconceptions and the understanding of students on diffusion and osmosis, and to examine the shifts in concept development that result from maturation and additional instruction. In addition, the textbooks were assessed for the sources of the misconceptions. The subjects of this study were 195 students in middle school, 191 students in high school and 195 students in university in Seoul. And the multiple-choice test developed by Odom and Barrow(1995) was used. The results were analyzed by two-way ANOVA in the statistical packages SAS. The major findings of this study are as follows. 1. The mean score of the understanding on the concepts of diffusion and osmosis of junior high school students was 31, that of high school students was 51 and that of university students was 67. In this study, the higher grade students got the higher scores, and it showed significant difference(p<0.01). 2. The mean score of girls was higher than that of boys in all grades. And the difference of the score according to gender showed great difference in high school(p<0.01). 3. An analysis of the patterns of misconceptions about diffusion and osmosis indicated that certain misconceptions prevail across grade levels. 4. An analysis of the contents of textbooks indicated that textbooks may be the source of students' misconceptions about diffusion and osmosis.

The prevalence of obesity and its related factors in adolescent girls in Seoul area were investigated from April, 18 to June, 29 1985 bymeans of anthropometry, dietary intakes and general environmental factors. Nine hundred and sixty junior high school girls were selected and invterviewed for 24-hour food intakes. Weight, height, a 우 skinfold thickness(triceps, abdominal) were measured and information on the general backgroun of the subjects were obtained by questinnaire. Subjects were divided into six groups according to their relative weights. It was observed that majority of the parents were under fifty years old and had high school education . In general, father was older and higher in educational levels than mother. Two thirds of subjects lived in their own houses and had three to four siblings. AVerage weight and height of subjects were 46.0kg and 154.4cm, which were higher than Korean natianl average. Average relative weight was 29.75 and average Kaup index was 1.925. Skinfold thickness was 13.4mm fo rtricepts and 16.4mm for abdominal . Prevalence of obesity was 12.9% and 4.8% by criteria of relative weight and skinfold thickness. Average intakes of most of nutrients except iron were acceptable but about one third of the subjects had less than 2/3 of RDa for calcium, iron, vitamin A, and riboflavin. As a whole, prevalence of obesity in this study was higher than those observed in the past surveys. Relationship of dietary intakes and general environmental factors that seemed to influence the obesity were integrated as such. As parents educational levels were higher, it tended to be higher in living standard and have fewer family members and siblings. These may influence more nutrient intakes so that fatness of the subjects seemed to be greater. In the meantime, parents fatness was closely related to those of children indicating an involvement of genetic factors. And also, food habits of individuals such as frequency of snack and bedtime snack were related to fatness significantly.

Objectives: This study aimed to determine the prevalence and correlates of sexual intercourse among junior secondary and high school students in Indonesia from the 2015 Global School-based Health Survey (GSHS). Methods: The survey was conducted among 11 110 students from 75 schools in Indonesia using a self-administered questionnaire. Univariate and multivariate analyses were conducted to explore associations between sexual intercourse and socio-demographic variables, substance use, mental distress, and protective factors. Results: Overall, 5.3% of students reported having ever had sex (6.9% of boys and 3.8% of girls). Of students who engaged in sexual intercourse, 72.7% of boys and 90.3% of girls had an early sexual debut (before reaching the age of 15) and around 60% had multiple sex partners. Sexual intercourse was associated with gender, school grade, smoking, alcohol consumption, drug use, suicidal ideation, truancy, peer support, and parental supervision. Conclusions: These findings indicate a pressing need to develop more comprehensive sexual health education in the national curriculum. An effective strategy should also address other risky behaviours.

In the Health Promotion Law proclaimed on January 1995, nutritional improvement at national level was emphasized and designated as one of the jobs to be carried out by local governmnets. With such a situational necessity, we conducted a dietary survey along with an anthropometric measurement, biochemical assessment and questionnaire analysis on general characteristics of the students from 3 junior higher schools in Seoul area. About 300 students had participated in the study and the data from only 139 students, 28 boys and 111 girls, with complete report of dietary intake were subjected to analysis, comparison and discussion. Fasting blood samples were drawn and analyzed for hemoglobin, hematocrit and total cholesterol. Dietary intake was monitored by 1-day 24hr recall +2-day food record. In general, the average intake of nutrients for most of the subjects were above RDA for korean of that age except for 2 nutrients namely, vitamin A and calcium, of which average intake corresponded to 46-69% of RDA. In addition to this kind of nutritional imbalance, there were several other factors of nutritional problems such as skipping breakfast, overeating at dinner and frequent eating of snacks. As the best countermeasure for these kinds of nutritional problems, more detailed campaign and prractical nutrition education for these adolescents are necessary. Only through proper education and guidance for them, the healthy and intellectual man power could be guaranteed for the forthcoming 21st century.
