A three factor experiment was conducted to explore the effects of giving prompts and asking for self explanation and the modulating effect of the need for cognition (NC) on the two interventions. The effects of giving prompts and asking for self explanation were different depending on the task and the level of need for cognition. Participants of low NC conditions showed the prompt effect and the self explanation effect in the memory tests. On the other hand, participants in the high NC conditions performed better in the comprehension test when they were given prompts and were asked to self explain. However, high NC participants performed worse when they were asked to self explain without providing the prompts. The results were interpreted to suggest the importance of detecting the right parts in getting the self explanation effect.

The purpose of this study was to examine whether self-differentiation mediates the relationship between adolescents' family functioning and self-esteem and to examine whether peer support and family conflicts had moderated mediating effects. For this purpose, 522 students from four high schools in Gyeonggi province were surveyed about their family functioning, self-differentiation, self-esteem, and peer support. The results were analyzed using SPSS 21.0 and PROCESS. The mediating, modulating, and moderated mediating effects were analyzed. The results of this study were as follows. First, correlation analysis showed that family functioning, self-differentiation, self-esteem, and peer support were significantly positively correlated. Second, the moderated mediating effects of peer support were as follows. First, self-differentiation had a partial mediating effect in the relationship between family functioning and self-esteem such that family functioning and self-differentiation were positively correlated and self-differentiation and self-esteem were positively correlated. Second, peer support had a moderating effect in the relationship between family functioning and self-differentiation that promoted self-differentiation. Thus, peer support affected family functioning and self-differentiation. Third, verifying the moderated mediating model of peer support by combining the mediation model of self-differentiation and the moderation model of peer support identified above showed that self-differentiation mediated the relationship between family functioning and self-esteem. Thus, family support affected self-differentiation and self-differentiation affected self-esteem. The significance of this study was as follows. First, it showed that self-differentiation significantly mediated the relationship between family functioning and self-esteem, clarifying the relationship between family functioning and self-esteem. Second, it showed that peer support moderated the relationship between family functioning and self-differentiation, identifying a mechanism that promotes self-differentiation. Third, it showed the mediation of self-differentiation of the relationship between family functioning and self-esteem depended on peer support.

The magnetocaloric effect and magnetization behaviors have been studied for $La_{1-x}Pb_{x}MnO_3$ (x=0.1, 0.2, 0.3) alloys. The Curie temperature increased from 195 K to 352 K with increasing Pb concentration. A large magnetic entropy change (${\Delta}S_M$), which is calculated from H vs M curves associated with the ferromagnetic-paramagnetic transitions, has been observed. The maximum ${\Delta}S_M$ of $La_{0.8}Pb_{0.2}MnO_3$ was 1.22 J/kg K at 294 K for an applied field of 1.5 T. Adiabatic temperature change (${\Delta}T_ad$) was measured directly by a special cryostat. The maximum ${\Delta}T_ad$ of $La_{0.7}Pb_{0.3}MnO_3$ was 1.00 K at 352 K for an applied field of 2 T.

The purpose of this study was to investigate the mediating effect of academic self-efficacy in the relationship between self-management competency and employment preparation behavior of senior nursing students. The data were analyzed using SPSS 26.0 program, frequency analysis, t-test, ANOVA, Pearson's correlation, and multiple regression. As a result of the study, self-management competency was positively correlated with academic self-efficacy, employment preparation behavior, and academic self-efficacy with employment preparation behavior. Academic self-efficacy showed a partial mediating effect between self-management competency and employment preparation behavior. The higher the level of self-management competency and academic self-efficacy, the higher the level of employment preparation behavior, and the explanatory power (R²) was 34%. Therefore, it suggests that it is important to develop self-management competency and to prepare an integrated strategy that can induce a sense of academic self-efficacy in order to promote the employment preparation behavior of nursing students.

The study has compared the effects in SNS-utilized instruction that each of self centric activities and social interaction added social activities affected self initiative, attitudes and self efficacy to information technology respectively. The research methods utilized the pre experimental design as nonequivalent experimental group. The data was analyzed by paired t-test and content analysis. The results showed that the SNS class utilized self-centric activities were effective in self-initiative and attitudes toward information technology, while social interaction added social activities were effective in not only self-initiative and the attitudes of information technology but also self efficacy of information technology. And content analysis of the effects of the education showed that information sharing, instancy and accessibility were advantageous but information security and privacy issues were problematic. That is, it was confirmed that when self-centric activities and social interaction activities were practised simultaneously in SNS-utilized instruction, the self initiative which learners planed and executed by themselves, the attitudes and self efficacy of information technology which were able to enhance learning ability and to show satisfaction to individual learning were improved.
