This study was performed to investigate the dietary habits and nutritional knowledge of elementary school students (boy : 250, girl : 250) by gender. Frequency of skipping breakfast was high in both boys and girls. Duration of mealtime was significantly higher for boys compared with girls (p<0.001). Regularity of meals was not significantly different between boys and girls. Reason for irregular meals was 'no appetite' for both boys (39.6%) and girls (40.0%). Unbalanced diet was high in both boys (60.8%) and girls (59.6%), and problems related to dietary habits were in order of 'unbalance diet', 'irregular mealtime', 'overeating', 'skip a meal frequently', and 'eat out frequently'. Frequency of snack intake was significantly higher for girls compared to boys(p<0.05). The criterion for selecting snacks was higher for 'nutrition' compared to 'good taste' for both boys and girls. Frequency of eating out was statistically insignificant, and eating out preferences were in the order of 'Korean food', 'western food', and 'Chinese food'. Eating behavior 'eat meat, fish, egg, tofu every meal' was significantly higher for boys compared to girls (p<0.01). 'Healthful' response rates were 57.6% for boys and 58.8% for girls. Practice level of nutritional knowledge was significantly higher in girls compared to boys (p<0.001). To establish good eating behaviors, we should develop systematic and continuous education programs.

Darta were analyzed with percentages, means, t-test, ANOVA, Kruscal-Wallis one way ANOVA, Scheffe test and pearson correlation coefficients using the SPSS program. The results were as follows: 1. The mean for the degree of obesity in subjects was -1.26%. The 34.2% of the subjects were underweight, the 46.8% were normal, the 9.2% were overweight and the 9.8% were obese. The girls who perceived themselves obese were 39% and only the 47% of them were really over-weight and obese. 2. The mean score of body image was 139.30. It was 145.51 for underweight girls, 128.07 for normal weight girls and 125.17 for obese girls. The higher the degree of obesity was, the lower body image score was. The body image score of the girls who perceived themselves obese was significantly lower than that of the girls who perceived themselves normal or underweight. 3.

They reported that they had used the following weight control methods such as diet(42.2%), exercise(35.9%), diet and exercise(15.1%) and others including drug(6.8%). The degree of obesity was significantly higher and the body image score was significantly lower in the case of the girls who had weight control experiences than in the case of those who had no weight control experiences. 4. The 60% Of the subjects often had 2 meals per day. The 48.8% of the subjects tended to skip breakfast, the 7.8% would skip lunch and the 20% did not have dinner.

Purpose: This study was done to identify contraceptive practices in adolescent girls in South Korea and predictors of contraceptive practices. Methods: The study sample included 743 girls who had experienced sexual activity. Using statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. Results: The contraceptive practice rate for adolescent girls was 34%. Contraceptive practice was associated with 'age at first intercourse' and 'sexual intercourse after drinking'. For adolescent girls who had early sexual initiation and drank alcohol before sexual intercourse there was a tendency to reduce the practice of contraception. Conclusion: It is necessary to provide practical sex education to improve the practice of contraception in these adolescents.

Sex-Role orientation was measured by the Children's Personal Attributes Questionnaire (Spence, Helmreich & Stapp, 1975) which was translated into Korean. An item analysis was done. For the data analysis, a three-way analysis of variance and t-test were applied. The results of the present study showed that 1) spatial ability gradually improved between 10 and 14 years of age. 2) There were no significant differences between girls and boys in the performance on the spatial ability test. 3) Masculinity in girls was not significantly associated with high spatial ability. However, there was a tendency for the masculine girls in the direction of higher spatial scores than feminine girls and undifferentiated girls. 4) Femininity in boys was not significantly associated with high spatial ability. However, there was a tendency for the feminine boys in the direction of higher spatial scores than masculine boys and undifferentiated boys.

The social behaviors of 177(84 girls, 93 boys) 5-6 year olds were rated by the SCBE teacher questionnaire. Mothers reported on their reactions to children's negative emotions and on children's emotionality by questionnaires. Results showed that girls' emotionality was related to maternal punitive responses and their withdrawn behaviors. Maternal emotion-focused reponses were associated with boys' social behaviors. Maternal distress reactions were correlated with girls' prosocial behaviors; maternal punitive responses were related to girls' prosocial and withdrawn behaviors. Maternal emotion-focused responses were associated with girls' aggressive behaviors. Partial correlation analysis indicated girls' emotionality was not related to their withdrawn behaviors when maternal punitive responses were taken into account.

the purpose of this study was to consider the lower bodyshape factor of girls according to their age groups. The subject were 150 Korean Elementary School Girls and 150 Korean Junior High School Girls. The subjects were directly measured anthropometrically. In first group(Elementary School Girls) the result of factor analysis indicated that 7 factors were extracted through factor analysis and those factors comprise 83.1% of total variance and in second group (Junior High School Girls) 8 factors were extracted through factor analysis and those factors comprise 79.9% of total variance. Lower bodyshape factors were different to each groups. So these systematic information on typical bodyshape were provide to reduce the burden of stocks and increase clothing fitness.
