The study examined whether the relation between mathematics self-efficacy and mathematics achievement was partially mediated by the learning strategies, using latent growth model analyses. It was also examined the auto-regressive, cross-lagged (ARCL) panel model for testing the stability and change in the relation of mathematics self-efficacy and learning strategy over time. The study analyzed the first-year to the third-year data of the Korean Educational Longitudinal Survey (KELS). The result of ARCL panel model analysis showed that earlier mathematics self-efficacy could predict later learning strategy use. There were linear trends in mathematics self-efficacy, learning strategy, and mathematics achievement. Specifically, mathematics achievement was increased over the three time points, whereas mathematics self-efficacy and learning strategies were significantly decreased. In the analyses of latent growth models, the mediating effects of learning strategies were overall supported. That is, both of initial status and change rate of rehearsal strategy partially mediated the relation of mathematics self-efficacy and mathematics achievement. However, in elaboration and meta-cognitive strategies, only the initial status of each variable showed the indirect relationship.

Objective : The aim of this study is to analyze the relationship among job stress, depression, and suicidal ideation in firefighters, particularly the mediating effects of depression. Methods : The subjects were 2,136 firefighters in Gangwon-do, who completed the short form of Korean occupational stress scale (KOSS-SF), Korean version of the Beck depression inventory (K-BDI), and the revised scale for suicide ideation (SSI) online in mental health promotion service of firefighters. The data was analyzed with correlation analysis among the variables, and the multiple regression analysis method of Bar-on and Kenny (1986) was used. Results : Job stress showed positive correlations with depression (r=0.493, p <0.01) and suicidal ideation (r=0.296, p<0.01). Depression showed a positive correlation with suicidal ideation (r=0.561, p<0.01). The result of analyzing the mediating effect of depression showed that depression was a full mediator variable between job stress and suicidal ideation. Conclusion : Based on the results, it is very likely that job stress may affect suicidal ideation via depression. These results suggested that the preventive interventions emphasized on depression may be helpful for reduction of suicide in firefighters.

This study investigated the relationship between maternal facilitative communication perceived by children and the social adjustment which was measured as pro-social behaviors and aggressive behaviors in children. Special attention was given to the mediating effect of the child's self-regulation on the relationship. The subjects, selected by convenience sampling method, were 193 fourth and fifth grade elementary school students. Data was analyzed through Pearson's correlation, reliability analysis, and multiple regression using the SPSS 12.0. The findings of the study were as follows. First, the mother's facilitative communication perceived by the child was positively associated with the pro-social behavior, while, it was negatively correlated with the aggressive behavior of the child. Second, the mother's facilitative communication had direct effect on the prosocial behavior and the aggressive behavior of the child. Third, the direct impact of facilitative communication on social adjustment was mediated by the self-regulation variable. Based on these findings, this study proposes strategies for the improvement of children's adjustment during late childhood.

This study examines the mediating effects of social support on 1) the relationships between acculturative stress and depression/anxiety and 2) the relationships between emotional control and depression/anxiety in children from multicultural families. Pearson's correlations between variables were analyzed, and hierarchical regression analyses were conducted to identify direct and indirect effects of acculturative stress, emotional control, and social support on children's depression/anxiety. The sample included a total of 199 primary school students in grades 3 to 6 who lived in the Gwangju or Chonnam regions of Korea. First, there were positive correlations between acculturative stress and depression/anxiety and negative correlations between emotional control and social support. Second, social support from both peers and teachers partially mediated the relationships between acculturative stress and depression/anxiety. Third, social support from peers fully mediated the relationships between emotional control and depression/anxiety, and that from teachers partially mediated these relationships. The results suggest that social support from peers and teachers may reduce depression/anxiety in multicultural children as a mediating variable.

본 연구는 학교 안전관리자의 인식이 학교안전의 전이의도에 미치는 영향요인과 매개효과를 분석하여 학교 안전 교육 프로그램의 개선방안을 제시하고자 한다. 연구의 결과를 종합해보면, 전이의도에 가장 영향력이 있는 변수로는 내용만족도로 나타났다. 그 다음으로 강사만족도, 환경에 대한 만족도 순으로 영향력이 있는 것으로 나타났다. 그러나 교육방법에 대한 만족도는 통계적으로 유의미하지 않은 것으로 확인되었다. 또한 학교 안전교육에 대한 일반적 인식은 학교관리자 안전교육의 만족도와 학교안전 전이의도의 관계의 매개효과가 존재한 것으로 나타났다.

This study aims to examine OL as a potential mediating variable in the relationship between IT and organizational performance. Organizational learning (OL) has been proposed as the mechanism to accomplish this task. Existing empirical research demonstrates that OL may indeed act as a mediator for the effect of IT on organizational outcomes. Also, existing literature discusses the use of technology in the organization, and the case for OL as the key knowledge process, and the intersection between technology and OL as a knowledge-based means for improving organizational performance. Many studies use a descriptive measure of OL despite the theory suggesting that a normative measure may be more appropriate. This study aims to address these concerns in a setting by using structural equation modelling (SEM) to compare the effectiveness of descriptive and normative measures of OL as mediating variables in knowledge-intensive organizations. Survey results support OL as a mediator between IT and organizational performance in addition to normative measures of OL outperforming descriptive measures. Implications for research and practice are discussed. To test the model, we will apply (SEM) structural equation modeling in the analysis of a moment structures (AMOS) on the empirical evidence collected from 218 Pakistani CEOs and top managers.

Purpose: Optimism is an important psychological variable that functions positively in stress adaptation process. The purpose of this study was to identify either a mediating or moderating effect of optimism in the relationship between stress and well-being among mothers of children with diabetes mellitus. Methods: A sample of 109 mothers of children with diabetes mellitus was recruited in a tertiary hospital in B city and they completed self-reported questionnaires. Multiple regression analysis models were used to test the mediating and moderating effects of optimism in the relationship between stress and well-being. Results: The results of the multiple and hierarchical regression analysis showed that the role of optimism was examined a partial mediator of the relation between stress and well-being, not a moderator. Increased stress was associated with decreasing optimism and well-being, and increased optimism predicted increased well-being among mothers of children with diabetes mellitus. Conclusion: Optimism is more likely to play a role as mediator, rather than as a moderator. This finding suggests the importance of optimism in improving the well-being of mothers of children with diabetes mellitus.

Tension and self-control are explanatory factors in adolescent delinquency, and internet addiction and anonymity are regarded as factors underlying cyber deviation. The aim of this study was to investigate the interrelationships between these factors and cyber deviation. Participants were 485 middle and high school students in the Jeonbuk region. The results showed that tension and self-control were predictors of cyber deviation and that internet addiction was a mediating variable for both the predictors. Anonymity was found to have a mediating role, but only in respect of the tension-cyber deviation pathway. These findings suggested a number of implications. Firstly, the educational programs on cyber deviation should be different from the existing deviation prevention programs. Secondly, measures to prevent internet addiction are needed for the effective prevention of cyber deviation. Lastly, the finding of a relationship between anonymity and cyber deviation indicates the need to adopt a long-term perspective drawing on values education techniques to develop a code of cyber space ethics for "netizens".
