The purpose of this study was to evaluate the effect of moderate physical exercise program on a number of immune parameters in middle school boys($15.07{\pm}0.39$ yrs). 14 volunteers were included in this physical exercise program. They were randomly assigned to an experiment(7) and a control(7) group. Measurements were taken before program, after 4 weeks and 8 weeks of aerobic exercise for immune parameters such as number of circulating leukocytes, concentration of WEC subsets, lymphocyte subsets, immunoglobulins, complements, and number of blood adipose components. Aerobic exercise consisted of track running at a work intensity of 65% HRmax, $45{\sim}55$ min per day, 3 times per week, and for 8 weeks. The results are as follows; 1. There were no significant changes between and within groups in the number of circulating leukocytes and concentration of WEC subsets. 2. There were significant(p<.05) changes in concentration of B-cell between groups, and T-cell, helper T-cell, and B-cell within experimental group. 3. There were no significant changes between and within groups in concentration of complements. 4. There were significant(p<.05) changes in concentration of IgG between groups and within experimental group. 5. There were significant(p<.05) changes in concentration of TG between groups, and TG, HDL-C and LDL-C within experimental group. In conclusion, the moderate exercise training for 8 weeks can be beneficial on immune function and decrease the concentration of flood adipose components in adolescents.

The purpose of this study was to examine the influence of family mealtime and family functioning (family cohesion, family adaptability, and communication with father and mother) on early adolescent school adaptation. Data of 3,145 middle school students from the Survey on the Family Values and Lives among Adolescents(2010) conducted by National Youth Policy Institute(NYPI) were used. The findings are as follows. First, there were significant differences in the frequency of having breakfast and dinner with father and having breakfast with mother, family cohesion, and communication with father according to gender. Second, hierarchical linear regression analyses revealed that household economic status, mother's employment status and adolescents' gender among demographic characteristics, having breakfast with father and having dinner with mother in family mealtime frequency, and all the variables of family functioning predicted adolescents' school adaptation. Finally, economic status, having dinner with mother, family cohesion, and communication with father and mother were associated with adolescents' school adaptation for both boys and girls. Mother's education and having breakfast with father were found to be significant for only boys, while mother's employment status and family adaptability were found to be significant for only girls. These findings could provide grounds for making family and education policy.

This study analyzed Korean students' affective characteristics in mathematical learning according to school and sex by Factor Analysis and Cognitive Diagnosis Theory. In numerical affective achievements by Factor Analysis, there are mean differences between schools, i.e. elementary school and secondary school. And there are sexual differences within schools and boys show more positive achievement than girls. By Cognitive Diagnosis Theory, I investigated 6 affective attributes' proportions that students achieved according to school and sex. Middle school students' proportion is highest in self-control and anxiety and the attribute that students achieved most in all school is cognizing mathematical value. Boys show higher proportion in self directivity, interest and confidence than girls, but girls show higher proportion in anxiety than boys.

Recently, endocnne dIsruptors have been known as one of the most harrnful chemical material. The purpose of this study is to investigate the cogintion and behavoor of milddle school students on the endocrine disruptors. To achieve this goal, survey research was conducted. Data were collected from 531 first and third-grade students in Suwon city. The main results of this study are summarized as follows FIrst, the mam source of information on the endocrine disruptors was mass media such as TV. This means environmental education in school is needed and mass media can be a very important tool for education. Secondly, as grades become higher, more students had knowledge on the endocrine disruptors. The difference between boys and girls was not significant. Thirdly, most students recognized endocrine disruptors as a dangerous material. However, they had an optimistic view on the possibility of resolving the environmental problems using science and technology in the future. Lastly, the scores of environmentally sound behavior was not highly correlated to those of knowledge. This means that in current environmental education system, more knowledge on the endocrine disruptors do not ensure more environmentally-correct behavior. These survey results show that environmental education on the endocrine disruptors should be constructed to induce correct behavior. That is, environmental education from now on has to be conducted to change the behavior of student as well as to increase knowledge.

The effects of a nutritional education program for first grade middle school students were evaluated from August to December, 2006. The study subjects were 82 boys and 90 girls, residing in Gwangju, Korea. To assess the effects of the nutritional education program, pre- and post-questionnaires examining nutritional knowledge, dietary attitudes, and dietary habits were developed. Paired t-test and repeated measures ANOVA were used to evaluate the effects of the nutritional education program. In the general subject, the main after-school activities were studying, watching TV, and using computer (85.5%), and sports (9.3%), suggesting their low physical activity. Parents (46.5%) were indicated as the source of nutritional education rather than teachers (13.4%). Twenty-five percent of girl students had diet experience of skipping meals (54.6%), suggesting the need of proper nutritional education for adolescents' health care. In dietary attitudes, both genders showed some improvement of recognition after education. In the changes in dietary habits, both genders had a significant effect on 'three meals a day, eating breakfast, and regular meal' after education. After education, the rate of having breakfast everyday increased from 52.4% to 65.9% for boys and from 33.3%to 57.8% for girls. In the changes in nutritional knowledge, the appreciation of the importance of school meals increased in both genders from 50.6% to 80.8% after education. The nutritional knowledge, scores of regular eating and well-mannered eating increased in both genders regardless of the students' characteristics. The study results revealed that this education provided an important motivation to improve basic nutritional knowledge and dietary habit. It is recommended to develop systematic and various educational programs and learning materials tailored to subjects before nutritional education.
