Climate change is significantly affecting coastal areas, and its impacts are expected to intensify. Recent studies on climate change adaptation and risk assessment in coastal regions increasingly integrate the concepts of recovery resilience and vulnerability. The aim of this study is to develop a measurement model for coastal hazard recovery resilience in the context of climate change adaptation. Before constructing the measurement model, a comprehensive literature review was conducted on coastal hazard recovery resilience, establishing a conceptual framework that included operational definitions for vulnerability and recovery resilience, along with several feedback mechanisms. The measurement model for coastal hazard recovery resilience comprised four metrics (MRV, LRV, RTSPV, and ND) and a Coastal Resilience Index (CRI). The developed indices were applied to domestic coastal erosion cases, and regional analyses were performed based on the index grades. The results revealed that the four recovery resilience metrics provided insights into the diverse characteristics of coastal erosion recovery resilience at each location. Mapping the composite indices of coastal resilience indicated that the areas along the East Sea exhibited relatively lower coastal erosion recovery resilience than the West and South Sea regions. The developed recovery resilience measurement model can serve as a tool for discussions on post-adaptation strategies and is applicable for determining policy priorities among different vulnerable regional groups.

The purpose of the study was to examine the mediating effect of self-esteem on the convergent relationship between respect for human rights and school adjustment of adolescents. Data came from the Korean Survey on the rights of Children and Youth in 2016 and a total of 2,366 of the 2nd grade students in middle school were employed. Structural equation modeling approach was utilized to test the goodness of research model fit and especially the mediating effect was tested by bootstrapping method. Results showed that goodness of model fit was acceptable and self-esteem mediated the convergent relationship between respect for human rights and school adjustment of adolescents. This indicates that the more experiences in respect for human rights and the higher their self-esteem students have, the better school adjustment they acquire. The results of the study imply that it is necessary to expand the human rights education for teachers and develop a new educational program that links between respect for human rights and self-esteem.

The purpose of this study is to define the paths through which academic burnout and self-efficacy of middle school students affect school adjustment, verify the path model of each factor, and examine the mediator effects of self-efficacy. In line with this objective, the study conducted a survey on 713 third year students of 3 different middle schools in city G. The first finding of this study confirmed that the path coefficient and suitablility index were significant, indicating that the path model was also significant. Second, academic burnout had direct negative effects on self-efficacy and school adjustment, while self-efficacy has positive effects on school adjustment. Third, self-efficacy was confirmed to have meaningful mediator effects on academic burnout and school adjustment. Based on these findings, academic burnout caused by excessive demand for academic success on korean students has negative effects on school adjustment, but if self-efficacy is well developed as an individual factor, school maladjustment can be reduced. Thus this study confirmed that psychological factors, such as self-efficacy, are necessary in school adjustment. Future studies were suggested on the basis of this study's findings.

The purpose of the current study was to investigate the causal relationship between school life adjustment and life satisfaction among adolescents through longitudinal panel data. The current study analyzed the 1st through 7th wave data in the 4th grade panel of elementary school from the Korea Children and Youth Panel Survey (KCYPS). The research model was tested using auto-regressive cross-lagged model. The major results were as follows. First, adolescents' school life adjustment had a positive auto-regressive effect. Second, adolescents' life satisfaction had a positive auto-regressive effect. Third, adolescents' school life adjustment was a causal predictor of life satisfaction, but not vice versa. Finally, implications in terms of enhancing adolescents' school life adjustment and life satisfaction were also discussed.

The purpose of this study was to explore the concurrent and lagged effects of parental neglect and abuse on longitudinal changes in late childhood school adjustment. This study utilized survey data from the fourth through seventh iterations of the Korean Child Youth Panel Study conducted on fourth-year elementary school students through first-year middle school students. The data was analyzed using latent growth modeling. The results were as follows. First, the level of school adjustment decreased gradually. Second, both neglect and abuse had concurrent effects on school adjustment. Third, neglect had lagged effects on school adjustment but abuse did not. The paper discusses the implications of these results. The results of this study can be used to better understand and support children who have suffered neglect or abuse adjust to school during late childhood.

시스템 다이나믹스는 전통적인 단선론적 인과론을 극복하고 시스템의 동태적 특성을 파악하는데 상당한 공헌을 하였다. 그러나 이러한 시스템의 특성을 방정식에 의존하는 시뮬레이션 기법(Equation-Based Simulation:EBS)을 이용하여 분석하는 경우 방정식으로 묘사하기 어려운 복잡적응시스템(Complex Adaptive System)에서는 한계를 갖고 있다. 따라서 시스템의 동태적 특성을 좀더 정확히 파악을 하기 위해서는 시스템을 구성하는 개체(agent)들의 행동이 시스템 전체에 미치는 영향들을 모형화 함으로써 파악하는 것이 바람직하다고 할 수 있다. 본 연구는 이러한 개체지향 시뮬레이션(Agent-eased Simulation: ABS)의 기법을 복잡성과학의 패러다임을 소개함으로써 그 중요성을 설명하고자 한다. 특히 카오스 이론으로부터 복잡성과학으로의 발전 과정을 개념을 중심으로 논의함으로서 복잡적응시스템의 이해를 돕고자 한다. 또한 ABS가 실제로 전통적인 EBS가 묘사하는 생태계 시스템의 변화를 잘 묘사할 수 있다는 사실을 보여주기 위하여 3개체가 있는 Lotka-Voltera 모형을 Cellular Automata 라는 ABS에 기반 한 시뮬레이션 기법을 활용하여 그 사용가능성을 제시하고자 한다.

Intelligent Tutoring System(ITS), which offers individualized learning environment that consider many learners' variable, is realized by the effective alternative to take the place of domain expert. Accordingly, research on Learning Companion System(LC) is currently noticing. However, to develop LCS which applies effective interaction, it is necessary to combine several LCs, and personalized knowledge base have to be made first. Therefore, in this paper, we propose the 'Knowledge Base Object Medel', which is based on connectionist' in cognition structure, represents learner's knowledge to self-learnig object, and grows adaptive object by proprietor, verify the validity. This model lays the groundwork for design of personalized knowledge base, offers clue to development of adaptive ITS using knowledge base object.

This study examines correlations among factors that reportedly affect adjustment to military life: self esteem, locus of control,, social support and stress coping strategies. The study also attempts to validate the structural model to enhance understanding of the process of adjusting to the military life. The subjects of the study were 447 listed soldiers from private to sergeant currently stationed and serving in an army post in Gangwon-Do, Korea. The following tools were used for this study. Based on self-inventory questionnaires, evaluations were made regarding self esteem, locus of control, social support, stress management, adaptation to military life. Reliability of each criterion was evaluated based on reliability examination, correlations among parameters were analyzed, and the structural equation model was validated to verify the research model. The results of the study can be summarized as follows. First, internal control and self esteem have significant positive influence on social support and stress coping. Second, internal control and self esteem affect adjusting to military life through social support and active coping, two factors mediated in this study to act as parameters between self-esteem and internal control and military adaption. This study emphasizes intervention such as establishment of a social support system and training for taking necessary actions as limitations of studies dealing with internal traits and military adaptation. Since the subjects of this study were chosen from an army based in a single location for convenience' sake, it may be difficult to generalize the results to analyze the entire military.
