The purpose of this study is to find out how important providing nutrition education to young students is. The study is based on the assumption that students' food behavior, nutrition knowledge and cognition of body image, weight control and nutrition education are considerably influenced by gender. A total of 495 students (249 boy and 246 girl students) were surveyed in one middle school located Siheungsi, Gyeonggido. The average height and weight of the boy and girl students are 164.6 cm, 54.4 kg and l58.5cm, 47kg, respectively. According to average BMI, the boy students($20.0kg/m^2$) are in the normal state. However, the girl students($18.2kg/m^2$) are underweight. For the status of meal intake, 52.4% of the students took breakfast everyday. Female students had dinner with lower intake frequency than males(p<0.05). For snack intake, the kinds of snack differ according to gender(p<0.05); more milk for male and more fruit for female students. The scores of dietary behavior based on Mini Dietary Assessment were 21.5/30 for male and 21.3/30 for female students. The nutrition knowledge scores of 4.6/10 for male and 4.6/10 for female students were not significantly different according to gender. The score of dietary behavior is based on Mini Dietary Assessment. The survey shows that in terms of the experience of weight control, 35.5% of the girl students have made an effort to watch their weight and 21.8% of the boy students have tried controlling their weight(p<0.0001). It turns out that the students who have been provided nutrition education are more satisfied with their body shape than those who have never been provided nutrition education(p<0.05).

The purpose of this study is to weigh the students' backpacks of middle school in daily use and to analyse their physiological responses and subjective senses when carrying backpack in order to promote healthy and comfort school life of girl middle school students. Two female students were subjects who answered the questionnaires on two types of backpack and their metabolism, perspiration and the changes of skin temperature were measured in constant environment chamber, $25{\pm}1$ and $49{\pm}10$% RH. They walked on the treadmill carrying the backpack with the increment of backpack weight, 2 kg, 4 kg to 6 kg. When the backpack increases to 6 kg, the discomfort parameters and responses increases rapidly. Comparing with general type, improved type of backpack showed good results in physiological responses, but not in subjective senses, such as the ease of movement, pain, or total preference, specially in 2 kg and 4 kg. The girl students prefer the general type of backpack which is of fashion and small, when it weighs light such as 2 kg or 4 kg, while they prefer the improved bag which is functional when it is heavy as 6 kg. The longer wearing time of the medium weight, for example, 4 kg without feeling or recognition of any discomfort due to fashion style, might cause the students' posture and health weaker or more vulnerable to the problems.

We made a visit 12 elementary school personally in the B city of Gyeonggi Province and gave out 552 questionaries in order to accomplish the purpose of this study. And we analyzed the 501 answer data except the unfittable data 51 sheets-in case of no answer or untruthfulness. The inspection of the personality used the Eysenck Personality Questionnaire(EPQ) and the questionnaires of the safety accidents in the school were reorganized of the questionnaires which were used in Chun-Ok, Joen(1997) and One-Yong, Kim(1999)'s study to correspond with our purpose of study. Answer sheets were gone through the t and x2 test by using the program of SPPS. First, elementary school students are in the formative period in the life of a man. So many students's personality was in the middle group rather than in high and low group. In regard of the distintion between the boy students and the girl students, the boy students had higher score in Psychoticism(P) but the girl students had higher score in Neutroticism(N). And Lie(L) was showing a little more score in the girl students. Second, there was significant difference in the investigation of safety accidents in school according to sex distinction. 1) Comparing the boy students and the girl students, the rate of accidents was higher in boy rather than girl. And there was significant difference. 2) Comparing the grade of the school, the rate of accidents was higher in upper grade than lower grade both girls and boys. 3) In the kind of accidents, the traumatic Injuries were very popular and the next were contusions. There was significant difference in the traumatic injury and nosebleed. 4) The results of injured parts showed that the injuries of foot, leg, hand, arm hold a large majority. And there was a significant difference in head, face, foot, leg and etc. 5) Most accidents broke out during the break time and then accidents happened after school were the next. The flowings were lunch time and class time.

This study was performed to investigate the dietary habits, body satisfaction and nutritional knowledge according to body image of middle school girl students (n = 284). The subjects were classified as lean, normal and fat groups according to body image. The weight, body mass index (BMI) and the score of body image were significantly higher in the students who recognized their body image as 'fat'. The satisfaction of present body image was significantly lower in students who recognized their body image as 'lean'. The interest in weight control and experience of weight control were significantly higher in students who recognized their body image as 'fat'. The necessity of nutrition education was higher in all groups (lean 67.2%, normal 59.0% and fat 52.8%). The products used to feel sweetened were sweetened ice (68.7%), processed milk (68.3%), confectionery (62.3%), carbonated beverage (55.3%), fermented milk (38.0%) and none (6.0%). The frequency of consumption of fruit juices and fried food was significantly higher in 'normal' compared to 'fat'. There was no significant difference in the frequency of consumption of snack and nutritional knowledge among the three groups. In the multiple regression analysis, the score of body image was negatively associated with the frequency of snack consumption in the 'lean'. The score of body image was positively associated with identification of nutrition labels and an interest in weight control but was negatively associated with satisfaction of present body image in the 'fat'. Based on these results, we conclude that, the middle school girl students need correct recognition of body image and continuous and practical nutrition education in order to maintain healthy dietary habits.

The purpose of this study was to investigate the weights of clothing that middle school girl students are wearing and ghow athe students evaluate their comfort sensations for the state-of-clothing and classroom conditions. The results obtained were as follows. 1. Average total weights of clothing of each month were 795.5g/m2 for May(23.4$^{\circ}C$), 539-590.6g/m2(26.0-31.2$^{\circ}C$) from June to August, 723.6g/m2 for September(25.6$^{\circ}C$) and 980.2g/m2 for October(24.$0^{\circ}C$). 2. Total weight was changed markedly from May to June and from september to October. The change was mainly by tops. Not much change was observed for the bottoms due to the fact that students were blue jeans irrespect of the environmental conditions. 3. Not significant relationship was observed between clothing weights adn comfort sensations. When the classroom temperature was 23.4$^{\circ}C$, more than 50% of the students answered comfortable. 4. Negative correlation was observed between amount of bottoms weight and Rohrer Index; in other words, fat students were less bottoms such as pants of skirts. 5. Negative correlation was observed between physical finess and amount of under shirts at the month of May, June and October; students with igher physical fitness scores wear less under wear when the environmental temperature changes.

The purpose of this study was to examine the effects of formative assessment with detailed feedback on students' science achievement, attitude, and interactions between the teacher and the students. For the study, 133 seventh graders were selected from a girl's middle school in Seoul, and assigned to the experimental and the control groups. The duration of the treatment was over a period of nine weeks. In the experimental group, detailed feedbacks on the solution, teacher's comments on the results, and relevant references were provided after each formative assessment. However, only the answers were presented in the control group. Prior to instructions, a achievement and a attitude tests were administered. After the instructions, follow-up tests which were similar to the pretests were also administered. The results showed significant difference between the two groups in science achievement. It was found that the usage of formative assessments with detailed and supportive feedbacks was more effective in stimulating students' interest, raising their confidence in the subject, increasing their participation, as well as reducing their anxiety. The results also strongly indicated that detailed feedbacks were more effective in improving the interactions of the teacher and the students. The results strongly suggest that formative assessment utilizing detailed and supportive feedback is a necessary component of effective science teaching and learning.
