The purpose of this study is to investigate the most rational method of grouping peers to understand the impact of peer relationship on individual development of elementary school students. For the study, students at a class of the 3rd year(male) and a class of the 4th(female) year at elementary schools in Busan and Ulsan were surveyed to see the differences between various methods of classification of peer relation subgroup on the basis of cooccurence of perception data and psychological preference data. Two questionnaires were used; a questionnaire of perception and a questionnaire of psychological preference. With the perception data, value of sharing relationship was applied to classify peer relation subgroup and with the psychological preference data, interest relationship was expanded to classify peer relation subgroup of more than third party relationship. The result of this study showed that in the case of girls, there was high congruency between the classifications of peer relation subgroup by perception data and by preference data, whereas in the case of boys, there was difference between the classifications of peer relation subgroup by perception data and by preference data, which implies that boys can form a peer group even if there is psychological difference among members but girls can form a peer group only when there is psychological preference among them. Such a result shows that there is difference between boys and girls in the process of forming peer relationship. It is suggested that comparison of fitness be made between classification of peer relation subgroup by a homeroom teacher, by perception data and by psychological preference for rational classification of peer relationship among male children.

The capstone design classes in the College of Engineering are often team project-oriented, and teamwork skills are reported to positively impact problem-solving abilities. While team project courses have various advantages, they also come with challenges such as social loafing and issues related to free riders, which consistently hinder the positive effects of team project courses. To prevent these issues, there is a need to provide a clear evaluation-reward system for team members' contributions. In this study, we examined the reliability of peer evaluation scores for team members' contributions and reviewed methods to incorporate them into team project grades. The review results indicated that peer evaluation scores are deemed to have considerable reliability from a qualitative perspective. However, due to the relatively small team size in team project courses (3 to 6 members per team), using the arithmetic mean of peer evaluation scores is statistically challenging. As a complementary approach, this study proposes limiting the reflection ratio of peer evaluation scores and applying a more macroscopic processing method, not the arithmetic mean, to incorporate peer evaluation scores for team contributions into grades.

In traditional unstructured P2P file sharing network, each peer establishes connections with a certain number of randomly chosen other peers. This would lead to redundant traffic and P2P network partition in mobile ad hoc network (MANET). We propose an approach to construct an efficient unstructured P2P overlay over MANET using underlying cluster-based routing (CBRP). One of the peers in the P2P network is used as a root-peer to connect all peers. Each peer maintains connection with physically closer peers such that it can reach the root-peer. The peer constructs a minimum-spanning tree consisting of itself, its directly connected neighbor peers and 2-hop away neighbor peers to remove far away redundant links and to build an overlay closer to the physical network. Due to on-demand nature of inter-cluster routing of CBRP, the positioning algorithm for MANET is used to retrieve the file by a peer from the source peer via shorter path in the physical network. We can show by simulation that our approach performs better in comparison with the existing approach.

This study aimed to investigate the influence of mother's responsive/restrictive parenting and peer attachment on academic stress in school-aged boys and girls. The participants were 493 5th, 6th graders from five elementary schools in Daegu and Gyeongbuk province. The collected data were analyzed through a t-test, multiple regression, hierarchial regression using SPSS Win 19.0. The results are as follows. (1) Level of academic stress of school-aged girls was higher than boys. (2) Responsive parenting of mothers was the most powerful explanation in academic stress of school-aged boys. However restrictive parenting of mothers was the most powerful explanation in academic stress of school-aged girls. (3) In boys, responsive parenting of mothers influenced their academic stress but peer attachment didn't influence the boys academic stress. In girls, responsive parenting of mothers and peer attachment influenced their academic stress, and interaction effects of responsive parenting of mothers and peer attachment on academic stress was observed. (4) Both boys and girls, restrictive parenting of mothers and peer attachment had influences on academic stress. And interaction effects of responsive parenting of mothers and peer attachment on academic stress was not observed.

Objective: The purpose of this study was to examine the effects of child abuse, children's peer attachment and self-esteem on children's depression/anxiety. In addition, the mediating role of children's peer attachment and self-esteem between child abuse and children's depression/anxiety was investigated. Methods: Using the data of 396 children in grades 4~6 from the Korean Welfare Panel Study (2015), this study was conducted by applying Structural Equation Modeling (SEM). Results: The results of this study were as follows. First, child abuse had a direct influence on children's depression/anxiety, and self-esteem. Second, children's self-esteem had a direct influence on depression/anxiety. Third, children's self-esteem had mediating effects on the relationship between child abuse and children's depression/anxiety. Fourth, children's peer relationships had a direct influence on self-esteem. But, children's peer attachment did not have a direct influence on depression/anxiety. The effect of children's peer attachment on their depression/anxiety was partially mediated by children's self-esteem. Conclusion/Implications: In conclusion, child abuse, children's peer attachment and self-esteem have a direct or indirect impact on the depression/anxiety of children.

This study examines the mediation effect of teacher-child interactions in the process of the impact of teacher's teaching-efficacy on childhood education institutions and classroom environment on peer-play interactions. We used data from 970 children aged between 49 and 55 months and 970 homeroom teachers from the fifth Korean Child Panel (2012) of the Korea Institute of Child Care and Education. The model fitness was excellent after data were statistically analyzed with model of structure to testify the relationship and effect among teaching efficacy, classroom environment, teacher-child interactions, and peer-play interactions. First, the analysis also showed that the teacher's teaching efficacy did not influence peer-play interactions directly, but gave an indirect effect on the peer-play interactions with the mediation of the teacher-child interactions. Second, the classroom environment directly and indirectly influenced the peer-play interactions with the mediation of the teacher-child interactions. Third, the variable of teacher-child interactions was fully effective as a mediating variable in the process of the teaching efficacy and classroom environment influence on teacher-child interactions. Teaching efficacy and classroom environment influenced the peer-play interactions through the mediation of the teacher-child interactions. The significance of mediation effect of the teacher-child interactions was verified through a bootstrapping method.

The purpose of this study was to investigate the correlation between children's perceptions of interpersonal relations (parents, family, and peers) and those of self, and to examine how the perceptions are related ot problem-solving and social preference. The subjects of this study were 625 children of 5th and 6th grade in 4 primary schools in Taejon City. Results showed positive correlations among four measures of social perceptions (to parents, to family, to peer, and to self). Therefore we have found generalization among children's representations across four interpersonal domains-that is, parents, family, self, and peer. Children's problem solving-behaviors were most significantly related with parents/family domains among interpersonal relationships. In the case of boys, direct path between the perceptions of parents/family and problem solving-behavior was significant, whereas girls' perception of parent/family was associated with problem solving-behavior both directly and indirectly, through girls' perceptions of self and peer. Social preference was highly correlated with perceptions of peer and of father. This study has found that both boys' and girls' peer representations were established for the role as mediators between parents/family representations and peer ratings of social preference. These findings revealed that the impact of family representations on peer rejection was mediated by children's beliefs about their peers.

This study examined the mediating effect of self-concept on the relationship of peer victimization and social anxiety in middle school students. Study participants consisted of 235 (122 boys and 113 girls) first to third graders from three middle schools located in Seoul and Gyung-gi province. The School Violence Experience Scale and the Self-Concept Scale were used to measure research variables in the Korean version of Social Anxiety Scale for adolescents. Descriptive statistics and Pearson's correlation coefficients were calculated to examine the general tendency of study variables. In addition, structural equation modeling(SEM) was used to examine the mediating model. The study results were as follows. First, the level of peer victimization of the middle school students decreased the self-concept level; in addition, the self-concept level had a significant negative effect on the social anxiety level. Second, the self-concept level fully mediated the peer victimization and social anxiety relationship. In conclusion, a higher peer victimization level resulted in a lower self-concept level, that produced a higher social anxiety level in middle school students. The results suggested that implementing effective interventions to prevent peer victimization and encouraging a positive self-concept in middle school students would make a significant contribution to reducing social anxiety.

The purpose of this study is to identify factors associated with effective peer-assisted learning (PAL) for nursing students. This review examined studies on PAL in nursing education. The literature was searched using terms including 'nursing & peer assisted learning,' 'nursing & peer learning,' and 'nursing & peer teaching.' Potentially relevant research on PAL was identified, and 12 studies were determined to meet the inclusion criteria. This review includes five qualitative, three mixed-methods, and three experimental studies published on the topic. In the studies reviewed, practicum classes were found to use PAL the most. Students of the same age were most commonly the subjects of PAL, as indicated in six papers. PAL has been suggested to affect participants' knowledge, self-efficacy, confidence, and anxiety. The findings indicate that interactions between peers promote learning and lead to mutually positive responses, which provide opportunities for self-development. Finally, students' learning outcomes improve and their confidence in their knowledge and skills increases as they experience the role of student nurse. These findings indicate that PAL can be utilized as an efficient learning method in nursing education programs. However, effective strategies for using PAL to achieve learning objectives and maximize learning outcomes are needed.

Objective: The objective of this study was to investigate the mediating effect of children's emotional intelligence on teacher-child intimacy perceived by children and peer acceptance. Methods: The participants were 134 five-year-old children(71 boys, 63 girls) attending daycare centers and kindergarten in Seoul and Gyeong-nam province. Children were interviewed to measure teacher-child intimacy and peer acceptance. Teachers completed rating scales to measure children's emotional intelligence. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, three step mediated regression analysis and a Sobel test. Results: The main results are as follows. first, there were significant positive correlations of teacher-child intimacy, emotional intelligence, and children's peer acceptance. Second, children's emotional intelligence had a partial mediating effect on teacher-child intimacy and peer acceptance. Conclusion/Implications: The results of this study demonstrates links between early teacher-child relationships and children's emotional and social development. In order to promote children's peer acceptance, it is necessary to build an intimate teacher-child relationship and to improve children's emotional intelligence based on that relationship.
