Objectives : Parental behavior is related to personality development and ego resilience in the childhood. The objective of this study was to identify the influence of parental behavior on ego resilience in Korean middle school student. Methods : Subjects were selected based on stratified multi-stage cluster sampling in Korea youth panel study 2013(Boy : N=1,075, Girl : N=1,033). We used Parental behavior inventory(PBI) to estimate parental behavior and the Ego resilience scale to estimate ego resilience. The data were statistically analyzed using a Pearson correlation analysis and regression analysis with the statistical package for the social sciences(SPSS). We considered differences to be significant when p<0.05. Results : A regression analysis showed that rational explanation, affection, Interest and inconsistency of the parental behavior domains influence ego resilience. Also rational explanation, affection and Interest of the parental behavior domains showed a significant positive correlation with ego resilience(r=0.24, r=0.31, r=0.22, p<0.01). In contrast to early childhood studies, inconsistency showed no significant correlation. Conclusions : Adolescents who had taken more rational explanation, interest and affection from their parents were more likely to have higher ego resilience. However, inconsistency of parental behavior showed no correlation with ego resilience of adolescents, which means that they are affected by several other factors than parental behavior. This study would be a basic research that could be a help to psychosocial approach in pediatric psychiatry.

Eating breakfast provides crucial nutrition for brain function and helps promote overall health. It is especially critical in growing adolescents, as it is known to form good eating habits and better study habits. This study investigated the effects of skipping breakfast on nutritional state, fatigue level, and attention level. A cross-sectional study was conducted in 2010 on total of 828 adolescents composed of 414 boys and 414 girls. Students who ate breakfast never to twice per week were placed in the breakfast-skipper group while students who ate breakfast more than five times per week were included in the breakfast-eater group. Students performed a self-reported questionnaire on food behaviors, amount of food consumption, fatigue level, attention deficient hyperactivity disease (ADHD) level by Conners-Wells' Adolescent Self-Report Scales, depression scale, and self-esteem level. Statistical analysis was conducted using the SAS program (version 9.1). A total of 135 boys (32.6%) and 138 girls (33.3%) were included in the breakfast-skipper group, whereas 241 boys (58.2%) and 223 girls (53.9%) were included in the breakfast-eater group. The breakfast-skipper group showed irregular food behaviors and lacked nutrients. Specifically, energy (p< .001), protein (p< .001), dietary fiber (p< .001), calcium (p< .01), vitamin A (p< .01), thiamin (p< .05), niacin (p< .001) levels in boy breakfast-skippers were statistically lower compared to boy breakfast-eaters. Intakes of all nutrients except fat in girl breakfast-skippers were statistically lower than in girl breakfast-eaters. Girl breakfast-skippers (41.3%) showed significantly higher fatigue risks compared to girl breakfast-eaters (21.5%). Low attention level was also observed only in girls in the breakfast-skipping group. Moreover, students in the breakfast-skipper group showed higher scores for depression and low self-esteem (p< .001). In conclusion, skipping breakfast has effects on young adolescents' nutrition, manifesting as high fatigue level and low attention level, especially in girls.

The purpose of this study was to evaluate appropriateness of clothing & textiles as educational contents in practical arts or technology home economics in the 7th curriculum. The factors of appropriateness were the amounts of learning, the degrees of understanding, interest and requirement on the educational content recognized by elementary, middle and high school students. The data collected from evaluation sheets were analyzed by frequency analysis, t-test, crossing analysis using SPSSWIN 12.0 program. Results were as follows; First. more than 50% of elementary, middle and high school students were recognized the amounts of tearing of clothing & textiles proper. But boy students of middle school recognized 'making clothes' in practice course too heavy. Second. It were from easy to difficult that the degrees of understanding on the educational contents of clothing & textiles recognized by elementary school students. Elementary school students understood both 'making cushion' and 'sewing machine theory and practice' difficult. Middle school students understood 'basic sewing for repairing clothes' and 'making clothes' difficult whereas high school students thought 'making pillow' and 'making bag' difficult. All students understood practice courses hard. Third, the degrees of interest showed from 'interest' level to 'not interest' level in case of elementary school students whereas 'interest' level in middle school students and 'common' in high school students. Fourth, the requirements of elementary, middle and high school students were in 'necessary' level to 'common' level. Editional contents such as 'learning sewing machine', 'making cushions'. 'making clothes', and 'making pillow-cover and bag' were low in the degrees of requirement. The correlationship between the amount of learning and the each level of understand, interest and requirement of students was indirect.

This study was conducted on 2016 $1^{st}$ and $2^{nd}$ grade middle school students in order to investigate of their perceptions and needs on sewing practice class, which had been experienced during their $6^{th}$ grade elementary school year. Implications and improvement for sewing practice class to be drawn from this study. The findings are as follows: Firstly, the levels of satisfaction with the practice contents and teaching learning method were higher than the median value(3.00). Among the subareas of class evaluation, participation scored the highest average, followed by interest, difficulty, necessity, importance, and utilization. In the entire subareas, girl students have more positive perceptions on sewing practice classes than boy students. Secondly, satisfaction with the practice contents has an effect on all subareas of class evaluation. The satisfaction with the teaching learning method has an effect on participation, interest, importance and utilization. Lastly, as for the practice contents, they would prefer household items and ornament, and want to choose sizes freely. As for students' needs for a new teaching learning method through which students are allowed to freely make objects or create works through a group activity, it was higher than the median value. This study showed that practice contents and teaching learning method are important factors that affect class evaluation. This study suggested that sewing practice class should be conducted freely choosing of practice contents, making the group works, group or student-led activities. If sewing practice class is designed in consideration of the results and students' needs for class, students' perceptions on class is expected to change in a positive way.
