This study was to examine the differences of Korean and Chinese high school students on classroom goal structure(i.e., mastery, performance-approach, and performance-avoidance), help-seeking behavior(i.e., help-seeking, and help-seeking avoidance), and school engagement(i.e., behavioral, cognitive, and emotional), and to identify the mediating role of help-seeking behavior in the links between classroom goal structure and school engagement. The final samples consisted of 290 Korean and 294 Chinese students in high school. Results were as followed. Firstly, Chinese students had a higher classroom mastery goal structure, classroom performance-avoidance goal structure, help-seeking and emotional engagement than Korean students, whereas Korean students had a higher behavioral engagement than Chinese students. Secondly, for Korean students, help-seeking and help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Moreover, for Korean students, help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. While, for Chinese students, help-seeking and help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. Also, for Chinese students, help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Therefore, help-seeking should be promoted in order to improve students' school engagement, and classroom mastery goal structure need to be created in order to encourage students' help-seeking.

This study examined the potential mediating mechanisms underlying the association between peer victimization and school adjustment. 521 children in the fifth and sixth grades were recruited from primary schools in Korea. Peer nomination and self-reports were used to measure peer victimization, cognitive representations, and school avoidance. Academic achievement records were obtained from official school records. The findings indicated that peer victimization contributed to school avoidance and academic achievement by different pathways. The association between peer victimization and school avoidance was indirectly mediated by perceptions of the self and peers. In contrast, peer victimization was directly associated with academic achievement.

This study was based on the 'Escape Theory' model suggested by Baumeister(1990). Based on this analysis framework, this study attempted to examine that complicated direct and indirect effect of school risk factors(risk of academic scores, risk of relation with teacher and risk of peer relation) on suicide ideation in adolescence, through negative self-esteem, depression and withdrawal coping. To this end, this study used the data from the '2008 Gyeongsangbuk-Do youth crisis survey' conducted by the Youth service center in province of Gyeongsangbuk-Do. The target number of this study was 2,335 students in the age group of middle school and high school. The result of the Analysis indicate that risk of relation with teacher among school risk factors was only one which affected directly and indirectly on suicide ideation. The other side, risk of academic scores and risk of peer relation had indirect effects, via negative self-esteem, depression and withdrawal coping. In conclusion, this study confirmed that school risk factors had effects on suicide ideation directly or indirectly, they were complicatedly connected, through negative self-esteem, depression and withdrawal coping. Therefore, Prevention program for adolescence' suicide ideation or suicide risk require integrated strategies and tactics.

In this study, we look at the effect that the achievement goal of specialized high school students has on academic self-efficacy and the difference in academic self-efficacy depending on achievement goal orientation. The purpose of this research is to help students to efficiently increase their academic self-efficacy, develop research and study life guidance measures to improve negative factors, and select professors and learning methods. To achieve the purpose, survey was conducted with achievement goal orientation measurement tools(26 questions) and academic self-efficacy measurement tools(28 questions) for 745 students of 18 specialized technical high school students in 5 districts. The results of this study are as follows. First, preference to task difficulty and self-controlling efficacy have highly positive correlations with mastery goal orientation and confidence and mastery avoidance goal orientation have highly negative correlations each other. Second, achievement goal orientation form of specialized high school students were divided into 5 forms; 'execution avoidance(34.8%)', 'mastery orientation(20.8%)', 'approach(17%)', 'avoidance competition(14.9%)', and'mastery avoidance(12.5%)'. In preference to task difficulty, 'approach'group showed the highest average point and 'mastery avoidance'showed the lowest average point. The average point of 'approach' group was higher than other groups in confidence, but 'mastery orientation' group showed the highest average point. Through the results of this study, academic self-efficacy makes an effect by a certain direction in accordance with achievement goal orientation and it's necessary to access academic problems differently according to student's goal directivity. Therefore, it's necessary to provide educational method by student type based on explanation about academic self-efficacy of achievement goal orientation of specialized high school students and analysis on achievement goal orientation form.

실 환경 로봇에 강화학습을 적용하기 위해서는 가상 환경 시뮬레이션이 필요하다. 그러나 가상 환경을 구축하는 플랫폼은 모두 다르고, 학습 알고리즘의 구현에 따른 성능 편차가 크다는 문제점이 있다. 또한 학습을 적용하고자 하는 대상이 실세계의 하드웨어 사양이 낮은 스마트 로봇인 경우, 계산량이 많은 학습 알고리즘을 적용하기는 쉽지 않다. 본 연구는 해당 문제를 해결하기 위해 Unity3D에서 제공하는 강화학습 프레임인 ML-Agents 모듈을 사용하여 실 환경의 저사양 스마트 로봇에 장애물을 회피하고 탐색하는 모델의 강화학습을 적용해본다. 본 연구의 유의점은 가상 환경과 실 환경의 유사함과 일정량의 노이즈 발생 처리이다. 로봇의 간단한 행동은 원만하게 학습 및 적용가능함을 확인할 수 있었다.

The main purpose of this study was to investigate structural associates among high school students' perceived parental autonomy support, growth mindset, grit and avoidant help-seeking behaviors. There were 419 high school students participated for this study, and their perceived parental autonomy support, growth mindset, girt and avoidant help-seeking behaviors were collected through on-line survey. Descriptive analyses, Pearson correlation analyses, Structural equation modeling and Boostrapping analyses were performed to explore those relations through SPSS 25.0 and Mplus 8.2. First of all, as the result, it was found that the perceived parental autonomy support had positive effects on growth mindset and grit. Second, the growth mindset worked as a negative mediator for the association between perceived parental autonomy support and avoidant help-seeking behaviors. The results suggested that we should consider not only relations with parents but also individual growth mindset to increase high school students' self-regulated learning. Also, theoretical and practical implications were discussed.

우리나라의 기술 교육기관은 취학인구의 감소와 힘들고 어려운 일을 회피하는 사회적 풍조 때문에 많은 어려움을 겪고 있다. 실업계 고등학교와 전문대학에 진학하는 학생의 수가 줄어드는 것은 이미 일반화 되었으며, 이제는 일부 대학에서도 정원을 채우지 못하는 경우도 나타나고 있다. 그리고 대학 졸업생들이 심각한 취업난을 겪고 있는 현실인 반면에 기업에서는 구인난을 호소하고 있다. 이 때문에 외국으로 생산 거점을 옮겨가는 회사도 생겨나고 있다. 이러한 현실은 국내의 교육체계에 심각한 문제가 있다는 것을 의미한다. 광기술 분야도 여기에서 예외가 될 수는 없으나, 각 대학이 자구노력을 계속하고 있고 산업의 수요에 맞추어 인력양성 체계가 개선되어 가고 있으므로 이러한 문제점은 점차로 나이질 것으로 기대되고 있다.
