This study was conducted to examine the needs of nutrition education based on analysis of the eating habits and nutrition knowledge among middle school students. The survey was conducted on 536 students (boys=216, girls=320) using a questionnaire. The average number of meals consumed was three (67.5%) and 58.0% of students reported having breakfast. Concerning the nutritional knowledge, students showed the highest score (girls, 0.90${\pm}$0.03 and boys 0.82${\pm}$0.04) for items describing the proper diet plan for obesity. Additionally, nutritional knowledge was found to have a significant effect on dietary habits. Regarding the necessity for nutrition education, high response rates for "For normal growth of students (44.8%)" and "Help to select proper food and choose safe food (24.0%)" were observed. Taken together, these findings indicate that consistent and systematic management is required under the institutional support by the school to improve students' perception regarding nutrition and to develop effective nutrition education.

The purpose of this study was to classify female students' somatotypes, to investigate the relationship between five somatotypes obtained from anthropometric measurements and to examine the relationship between the spinal deformity and somatotypes. The subjects for anthropometric measurements were 844 female middle and high school students. The data were analyzed by cluster analysis, correspondence analysis, Duncan test, and T-test. The results were as follows. Cluster analysis on the factors extracted from directly measured items classified subjects into five types (middle height and a little slim type (39.6%), low height and a little slim type (13.1%), middle height and a little fat type (18.0%), tall and very fat type (7.7%), and very tall and standard type (21.6%). In examining the relationship between the normal people and those of the spinal deformity, the normal showed higher mean value in almost all the items of the girth, the depth, and the length. High school students had more spinal deformity in number than middle school students. The degree of deformity was higher in the right spinal deformity than in the left spinal deformity as the age increased. In terms of the distribution of the spinal deformity classified by the somatotype, Type 1 (middle height and a little slim type) and Type 5 (very tall and standard type) appeared the highest.

In this study, the attitudes of about 1200elementary and secondary students towards sciences lessons and scientists were investigated. For the survey of this study, simillar numbers of students in Seoul were selected from the 5th, 8th and 11th grades and from both sexes. For the attitudes towards science lessons, in the survey questionnaire, there were questions on the type of science lesson which students prefer and on student's assessment of science lessons which they receive. For the attitudes towards scientists, there were questions on scientists whom students respect, on students assessment of scientists and on students assessment of themselves. Results of this study can be summarized as follows: (1) A great majority of students prefered the laboratory-based to classroom-based lessons, but this tendency was less apparent in olderstudents.More boys, compared with girls, prefered laboratory-based study. (2) The student's assessment of science lessons was positive in the elementary school, neutral in the middle school and negative in the high school level. Boys showed more positive attitudes towards the study of science. (3) Apparently more girls than boys mentioned Madam Curie as a scientist whom they respect, Students tended to respect scientists in terms of their personalities rather than their cognitive abilities. (4) Students tended to assess that scientist's are more able than themselves in cognitive areas while themselves are better in affective areas. The gap between student's asessments of scientists and that of themselves became bigger in high school students. The gap between boy's assessments of themselves and girl's assessments of themselves was bigger in high school level than in middle school. (5) The decline of students attitude towards science lessons was bigger than their attitude towards scientists.

To examine closely the relations between food habits, food preferences and personality traits, 141 boys and 146 girls in the 5th and the 6th grade of primary school in Incheon were studied by questionaires. The results of this study were as follows: 1. In food habit scores, girls got 2.28/3.00 and boys got 2.24/3.00 which meant boys and girls had the similar food habits. 2. The higher were their activity, sociability, responsibility, reflectiveness, and superiority, the higher score they showed in food habits. 3. Meats, fats and processed foods had much to do with emotional stability, and those who belonged to high group in emotional stability high preference for them. But girls who had high preference for meats were low in emotional stability. 4. Fishes of which bones we can eat, and potatoes had relation to activity, and those who belonged to high group in activity showed high preference for them. 5. Vegetables and processed foods had relation to sociability. Those who belonged to high group in sociability showed high preference for vegetables, but those who belonged to middle group in sociability showed highest preference for processed foods. 6. Meats and potatoes had much to do with responsibility. Those who belonged to low group in responsibility showed high preference for them. 7. Those who belonged to the high group in emotional stability, and superiority showed the high preferene for foods respectively, and superiority showed the high preference for foods respectively.

Objectives The Eum-Yang (Yin-Yang in English) temperament was shown to have clinical and structural validity with Sasang Personality Questionnaire (SPQ), however the studies of the association with behavior problems and personality structure in adolescents were not satisfactory. The purpose of this study was to examine the relationships between Eum-Yang temperament and behavior problems in Korean middle school students. Methods 122 first grader of middle school students (68 boys and 54 girls) completed SPQ, Junior version of Temperament and Character Inventory (JTCI), and Youth Self Report (YSR). The correlations between SPQ, JTCI, and YSR subscales were investigated. And, also the differences between SPQ, JTCI, and YSR subscales among Yang (high 30% of SPQ total score) and Eum (low 30% of SPQ total score) temperament groups classified with SPQ total score were examined. Results The SPQ total score were correlated with Novelty-Seeking (r=.321) and Reward-Dependence (r=.392) in boys, and with Novelty-Seeking (r=.427) and Harm-Avoidance (r=-.444) in girls. The SPQ total score were not significantly correlated with Body Mass Index, Ponderal Index and YSR total, however significantly correlated with YSR Internalizing problems and Withdrawal/depressed subscale (r=-.242 and r=-.419) in boys and Withdrawal/depressed subscale (r=-.449) in girls. There were significant differences between Eum and Yang groups in Novelty-Seeking, Harm-Avoidance and Withdrawal/depressed as for boys and girls. Conclusions The biopsychological structure of SPQ was confirmed with middle school students. The behavioral (SPQ-B) and emotional (SPQ-E) perspectives of Eum-Yang were found to be protective and risk factors, and also correlated with Externalizing and Internalizing behavior problems, respectively. The biopsychological characteristics of Eum-Yang temperament and its relation with psychopathological symptoms in late-childhood should be carefully analyzed.

Objectives: Maintaining a balanced diet and thus health is crucial for adolescents, and the first step for balanced diet practice is meal planning. Adolescents, however, find it difficult to plan their meals. This study thus was set out to design an easier way of planning meals for adolescent girls. Methods: A dish-based target pattern for adolescent girls was tabulated, and validity of this was examined. Meal plan applying a dish-based target pattern was prepared by 150 female middle school students, and nutritional adequacies of those meal plans were examined. Validity and adequacy were tested by energy content, energy contribution ratio, nutrient adequacy ratio (NAR), probability of nutrient inadequacy, index of nutritional quality (INQ) calculation. Results: A dish-based target pattern with 11 dish groups was validated for nutritional adequacy. Though the NAR of calcium was 0.96, the INQ of calcium was 1.00. The average energy supply from the meal plans was 2,379 kcal, higher than the estimated energy requirement of a female middle school student, but the energy contribution ratio of carbohydrates, proteins, and fats were all adequate according to the acceptable macronutrient distribution range (AMDR). NAR of all nutrients examined were 1.0, except for calcium. The NAR and INQ of calcium were 0.87 and 0.75, respectively, and the meal plans at risk for calcium inadequacy was 19.30%. Conclusions: A dish-based target pattern proposed for adolescent girls was valid, but the meal plan prepared by female middle school students using this approach was high in energy and low in calcium supply. To cut down the energy supply from the meal plan, it is necessary to recommend dishes low in fat and use low fat cooking methods. To increase the calcium supply, it is important to recommend seaweed and legume group dishes with higher Ca INQ food items.

This study was designed to assess the iron nutritional status of girls at puberty in Kangnung area. The subjects consisted of 161 adolescents in sixth-grade in primary school and first-grade in middle school girls. Anthropometric measurements were taken for body weight, height, percentage of body fat, and circumferences of waist and hip. Nutrient intakes were assessed by modified 24-hour recall method. Food models and other measuring tools were also used. Fasting blood samples were obtained and analyzed for hemoglobin(Hb) concentration, hematocrit(Hct), serum iron(FE) and total iron binding capacity(TIBC). Mean values for Hb, Hct, Fe, TIBC, TS and serum ferritin were $13.6{\pm}0.9g/dl$, $39.6{\pm}3.9%, 91.3{\pm}36.3{\mu}g/dl$, $327.9{\pm}45.2{\mu}g/dl$, $28.3{\pm}11.8%$ and $37.4{\pm}24.2ng/ml$, respectively. Prevalence of iron deficiency greatly varied by indices from 4.8% when judged by Hb to 18.4% by serum Fe concentration. The Hb concentration was positively correlated with Hct(r=0.641), serum iron(r=0.266) and transferrin saturation(r=0.237)(p<0.05). On the other hand, serum ferritin concentration showed significantly negative correlation with TIBC(r=-0.572). Mean daily intake of iron was 14.94mg and heme iron intake was 1.13mg and which was 7.6% of total iron intake. Total absorbable iron calculated by the method of Mosen was 1.38mg and bioavailability of dietary iron was 9.3%. These results suggest that the prevalence of iron deficiency of pubertal girls is very high, therefore the guidelines for diet and social supports, such as, school food service system should be provided to improve their iron status in middle school students.
