The purpose of the study shall be to achieve an understanding of learning and emotional support services for adolescents being raised by their grandparents. In-depth interview and qualitative methodology were used to find changes in the service experiences of 10 adolescents being raised by their grandparents by analyzing their experiences at a health family support center. 1 agency in the Chungnam area was selected as a model for its program for adolescents being raised by their grandparents. Ultimately, 78 items as sub-concepts, 44 items as sub-categories, and 4 items as subjects were identified. Specifically, these included school achievement, peer group relationship, family relationship and significant others. In conclusion, they were found to experience slower physical and emotional development and tend to withdraw in social situations. They were also found to have experienced difficulties in communicating with other people and with school achievement. However, it was shown that these adolescents have made positive changes after participating in a program involving a family coach who supports and provides services for them. Also, they were found to have experienced psychologically changes, and improved in their school achievement and personal relationships. Consequently, we will require more effort to provide emotional support, adult role models, counseling intervention, and social support for them.

Purpose: This study was conducted to investigate factors affecting the somatizationof 4th grade elementary school students in South Korea. Methods: The research used cross-sectional data of 2,031 first grade elementary school students that participated in 4th-year Korean Children and Youth Panel Survey (KCYPS). Data analysis, which included descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation, and hierarchical regression,was performed using SPSS/WIN 23.0. Results: Aggression (r=0.60, p<.001) and depression (r=0.69, p<.001) showed significant positive correlation, while affection (r=-0.22, p<.001), reasonable explanation (r=-0.28, p<.001), peer relationship (r=-0.06, p=.001), and teacher relationship (r=-0.20, p<.001) were negatively correlated with somatization of elementary school students. Hierarchical regression analysis revealed that depression (${\beta}=0.52$, t=25.52, p<.001), aggression (${\beta}=0.27$, t=13.30, p<.001), reasonable explanation (${\beta}=0.05$, t=2.99, p=.002), and affection (${\beta}=0.04$, t=2.13, p=.031) were significant predictors of somatization. This regression model has an explanatory power of 52.8%. Conclusion: To reduce somatization, it is necessary to develop a therapeutic intervention to change student emotions into a positive coping mechanism and strategy. The results of this study will contribute to the development of programs and practices for healthy school life.

학급에서의 아동 상호간의 관계 파악은 아동 성향 파악 및 생활지도 등에 유용하게 사용될 수 있다. 이러한 교우관계를 파악하게 되면 서로 잘 어울리는 친구들이나 외톨이로 있는 아동을 미리 찾아내어 아이들 상호간의 감정의 흐름을 파악할 수 있고 서로 협력하는 학급을 만들기 쉬울 것이다. 이에 본 논문에서는 학급 아동 상호간의 호감도에 의해 교우관계를 분석할 수 있는 시스템을 퍼지 (Fuzzy) 이론을 응용하여 설계하고 그룹화 할 수 있는 방안을 제시하였다. 교우관계의 특성상 애매모호하고 불확실한 감정과 호감도를 몇 마디 말 또는 '좋아한다', '좋아하지 않는다'는 이분법적인 방법으로 분석하기에는 아동 상호간에 복잡한 감정을 다 표현하기 어렵기 때문에 퍼지이론을 적용하여 수치화된 정보로 상대적 비교가 가능하도록 함으로써 좀 더 정확한 아동 상호 관계를 분석할 수 있도록 설계하였다. 또한, 퍼지이론을 바탕으로 연결차수를 계산한 그룹화 방안을 제시하였다. 본 논문에서 제안하는 시스템과 분석화 방법의 특징은 첫째, 인간관계의 애매하고 모호한 점을 상대적 비교가 가능하게 함으로써 정확한 분석을 가능하게 하고, 둘째, 퍼지 이론의 적용을 통하여 해밍거리 (Hamming Distance)에 의한 유사도 분석이 가능한 시스템과 $\alpha$-수준집합 ($\alpha$-cut)에 의한 그룹화 방법을 제안하였으며, 셋째, 교육현장에서 발생할 수 있는 애매한 상황과 아동의 성향파악 등 수치적인 파악이 불가능한 부분을 분석이 가능한 데이터로 만들 수 있는 기초를 마련하였다.

This study aims to examine the relationship between physical education class activity of youth, smartphone dependence and school life adaptation. The data set of Korean Children and Youth Panel Survey(KCYPS) by National Youth Policy Institute was reanalyzed for this study. The subjects of this study were 2,351 second grade middle school students from 2011. The data were coded with the use of the statistics program on Windows, SPSS 23.0. To analyse the data, descriptive analysis, reliability analysis, one-way ANOVA and regression analysis were employed. The findings of this research are as follows. First, the difference between the activity hours of youth physical education classes and the reliance on smartphones is less dependent on smartphones as they participate enthusiastically in physical education classes. Second, the difference of physical education class activity time and school life adaptation among adolescents was more positive for school life adaptation as learning activity, peer relationship and teacher relationship were more active. third, the dependence of youth on smartphones has a positive effect on learning activities and school rules as the reliance on smartphones is low.

The purpose of this study was to examine whether adolescents' parental rule obedience moderates the relationship between maternalmonitoring and problem behavior (drinking and vandalism). Participants were 398 adolescents attending a middle school (6th through 8th grades) in a semi-rural mid-Atlantic community in the USA. Data were collected by questionnaires including items regarding relationships with parents, problem behavior, and peer relationships. Hierarchical multiple regression was usedto analyze the data. Results indicate that maternal monitoring is negatively related with adolescent drinking and vandalism. However, the negative relationship varies as a function of adolescents' parental rule obedience. The relationship was stronger among adolescents with lower level of parental rule obedience than among adolescents with higher level of parental rule obedience. Findings from this study suggest that research on maternal monitoring during adolescence needs to take adolescents' personal characteristics into account to better understand the process. They also suggest that parents could lower the possibility that their children's will be involved in drinking and vandalism by maintaining quality relationships with their children because children are more likely to internalize their parents' rules and standards when they have positive relationships with parents.

The purpose of this study is to provide basic information on clothing preference to help teachers suggest clothes that help students adapt better to school life, and to get basic data specific to Home Economics curricula and how teenagers' attitude toward clothes correlate with their conformity to school as a whole. The survey of 587 students was conducted between December 17-24, 2012 in Gwangju. The data was analyzed using the SPSS 18.0 for window program: frequency, means, factor analysis, cluster analysis, Chronbach's ${\alpha}$, t-test, and ANOVA. There were significant differences in the many adolescents's adapted to school life based on the clothing behavior conformity and the attitude toward the name-brand. The results showed that, if it is not extreme, adolescents had the more the clothing behavior conformity on peer & mass media than less, they did well adapt on school life. And the group of more preference for the name-brand clothing result in low school discipline adaptation but high peer and teacher relationship. In adaptation of learning, they were not different significantly based on attitudes toward the name brand.

According to the online learning environment, learning activities using mobile technology have emerged as a major concern. The features of mobile technology show potential supporting the emergence of learners' agencies in science education. In this study, 22 research literature on mobile activities in science teaching and learning published in Korea from 2011 to April 2020 were selected. First, the framework of Suarez et al. (2018) was revised and the types of mobile activities were categorized and investigated. Second, the emergence of agencies was examined in the context of science teaching and learning. And also, the relevance of mobile activity types ('Access to content', 'Data collection', 'Peer-to-peer communication', 'Contextual support') to support learners' agency dimension ('goals', 'content', 'action', 'strategy', 'reflection', 'monitoring') was analyzed. The first analysis show that science teaching and learning through mobile activities are changing from traditional to student-centered. Through these activities, students become more involved in learning and get the opportunity to become agents of learning. As a result of the second analysis, it has been confirmed that the emergence of learners' agencies has been supported and strengthened through mobile activities. Whereas, it needs to look upon the relationship between learners' agency and mobile activities in the overall context of science class. This consideration led to implications for the use of mobile technology in future science education and the transition to student-centered education.
