To assess the nutrient intakes and diet quality of middle school students living in Kangneung area a dietary survey using th 3-day food record was conducted with 226 subjects. Mean daily energy intake was 2114$\pm$502 kcal with 61.6% of energy supplied by carbohydrate 16.4% by protein and 22.0% by fat. As well as insufficiencies in calcium and iron intakes the bioavailability of calcium and iron consumed is considered to low because most of them came from plant origins. For calcium iron vitamin A and vitamin B$_2$the proportions of subjects with intake levels less than 75% of RDA were all over 46%. The mean adequacy ratio(MAR) an index of overall dietary quality was 0.70 for males and 0.73 for females. The indexes of nutritional quality (INQ) were over 1 for most nutrients except 4 nutrients; 0.48 of calcium 0.64 of iron 0.73 of vitamin A and 0.79 of vitamin B$_2$. Nutrient intake levels less than 75% of RDA may be appropriate as a criteria for insufficiency of nutrient intakes. Based on these results it is evident that some of middle school students in Kangneung area did not consume enough nutrients especially calcium iron and vitamin A.

This study is designed to identify the current condition of male students ostracized as the black ship (Wangtta in Korean) in middle schools and the effects of the Guardian Angle program on the decrease in Wangtta. 428 frist graders of two junior high schools were devided into two groups, a test group (n=195) and a control group (n=233). SPSS/PC+ program was used for analysis of the data, including frequency analysis, ANOVA and x(sup)2-test. The outcome of research can be summed up as the following 74.7% of the subjects thinks that there is Wangtta going on in there classes. Wangtta often comes to pass during the recesses (74.2%) and lunch times (51.6%). Those who are easily exposed to Wangtta are most likely to be both snobbish and pedantic. Those who lead Wangtta turn out to be good at fighting (56.4%) and dominant in the hegemony of the class depending on the way of ignoring or not playing with the victims(69.3%) In the case of bearing witness to Wangtta. 36.9% of the subjects try to overlook the case. Now let me take a look at the effect of the guardian angle program on the decrease in Wangtta. The program has a significant effect on the decrease (p<0.05) in the number and the phenomena of Wangtta perceived by students in both advance and post tests. The program makes a significant difference in the aspects of students’ behavior in relation to Wangtta in a desirable way (p<.01) Though the sociality index of the victims doesn’t show any significant difference statistically, it exerts a generally positive effect.

Objective : This study was designed to investigate the frequencies and the relation of stressful life events and health problems and evaluate the influence of stressful life events on the physical symptoms and anxiety in adolescents. Method : Newcomb's 39-item life-event questionnaire and Newcomb's 19-item health problems questionnaire were administered to 475 adolescents. The frequencies of stressful life events and health problems which had actually occurred to them during the previous 12 months were investigated. Items of stressful life events were classified in 8 dimensional scaling factors(Family/parents, Accident/Illness, Sexuality, Autonomy, Deviance, Relocation, Distress, Items not in scales) and items of health problems were classified in 5 health problems(General, Heart and Lung, Nervous system, Anxiety, Psychosomatic symptoms) and the correlation between them was analyzed. Result : 1) The average number of events occurring during the past year for the 475 adolescents is 3(7.7%). The most frequent item of stressful life events was 'Thought about suicide' and dimensional factors of "Distress" and "Autonomy" were the most frequent life events in multidimensional sacling analysis. There were more factors of "Family/Illness" and " Autonomy" in male, while there was more factor of "Distress" in female. There were more factors of "School violence" and "Deviance" in younger students, while there were more factors of "Sexuality" and "Autonomy" in older students. 2) The most frequent item of health problem was 'excessive fatigue' and "anxiety" was most frequent health problem in multidimensional scaling analysis. There were more health problems in female than those in male. The higher grades the students became, the more health problems they have reported. 3) There was significant relationship between 7 factors of stressful life events except one factor of "Relocation" and 5 health problems. Conclusions : These findings suggest that as adolescents grow older, they are engaging in more controllable behaviors related to autonomy and sexuality and at the same time are experiencing increased difficulty with distressful or discomforting events, and their stressful life events are significantly related to decreased health and psychological functiong.
