This study explored how peers influence on adolescents' game over-indulgence. More specifically, it was examined the effects of emotional support, subjective norm of game use, peer stress, and friends' attitude toward gaming on game over-indulgence. Results showed that the higher level of subjective norm of game use and peer stress one received the higher level of game over-indulgence one reported. However, lower emotional support caused higher game over-indulgence. Meanwhile, friends' attitude toward gaming was not significantly related to game over-indulgence.

Propagation time on permissionless blockchain plays a significant role in terms of stability and performance in the decentralized systems. A large number of activities are disseminated to the whole nodes in the decentralized peer-to-peer network, thus causing propagation delay. The stability of the system is our concern in the first place. The propagation delay opens up opportunities for attackers to apply their protocol. Either by accelerating or decelerating the propagation time directly without proper calculation, it brings numerous negative impacts to the entire blockchain system. In this paper, we thoroughly review and elaborate on several parameters related to the propagation time in such a system. We describe our findings in terms of data communication, transaction propagation, and the possibility of an interference attack that caused an extra propagation time. Furthermore, we present the influence of block size, consensus, and blockchain scalability, including the relation of parameters. In the last session, we remark several points associated with the propagation time and use cases to avoid dilemmas in the light of the experiments and literary works.

This study aimed to investigate how child neglect abuse by parents, children's intimacy with teachers and peer attachment influenced boys' and girls' psycho-social maladjustment(aggression, social withdrawal and depression). The subjects were 2,264 elementary school students(boys: 1,180, girls: 1,084) in upper grades participating in the Korea Child Youth Panel Surveys. The data were analyzed with descriptive statistics, correlations and hierarchical regressions. The main results of this study were as follows. Firstly, regardless of children's sex, as child abuse levels by parents are higher, so children's aggression levels are higher. Also, children's intimacy with teachers and peer attachment moderated the effects of child neglect abuse by parents on both boys' and girls' aggression. But the patters of moderating effects were differed in children's sex. Secondly, child neglect abuse by parents didn't influence boys' and girls' social withdrawal and boys' peer attachment moderated the effects of child neglect by parents on boys' social withdrawal. Finally, child abuse by parents strongly influenced boys' depression, but child neglect by parents strongly influenced girls' depression. Also, there were no moderating effects of children's intimacy with teachers and peer attachment on the relation between child abuse neglect by parents, and boys' and girls' depression.

This study aims to reveal whether attachment relationship with parents can differ from children being accepted and rejected in peer relations, and whether children's rejection sensitivity can differ from children having secure and insecure attachment relationship with parents. Subjects were 218 students in fifth and sixth grade of primary school. Inventory of Parent and Peer Attachment(IPPA), Children's Rejection Sensitivity Questionnaire(CRSQ), and peer relation sociometrics were used as measurements. The results showed that children in secure attachment with parents had lower scores on the subscales of CRSQ, such as anxiety, anger, belief, and psychological reaction, than children in insure attachment relationship with parents. And IPPA scores were higher in children being accepted in peer relation than children being rejected. These results can be considered that early attachment relationship with parents may influence children's rejection sensitivity and peer relation.

The purpose of this study is to examine how the level of participation in dance classes affects the development of social skills and peer relationship. The results are as follows: First, in terms of social skill development and peer relationship based on demographic characteristics, competition-a sub-factor of peer relationship-was higher in male students. In terms of grade level, confidence-a sub-factor of peer relationship-was high in second year students. Second, in terms of the effect of dance class participation on social skill development, autonomy, achievement, and cooperation-sub-factors of social skill-were significantly influenced by the period of participation in dance classes. Participation frequency, on the other hand, was found to significantly impact accountability and activity. Such results indicate that longer dance class participation periods more significantly influences social skill development. Third, in terms of the influence of dance class participation in peer relationship, students who participated in dance classes longer experienced positive impacts regarding sub-factors of peer relationship. Longer participation periods were correlated with lower hostilities. That is, longer participation period and time, as well as, higher participation frequency, have impact on peer relationship.

The purpose of this study is to investigate the effect and difference of hotel chef's peer pressure on self-efficacy and collective efficacy, and to examine the relationship between job satisfaction and job performance. For the study, questionnaires were distributed to 6 hotels in Seoul and Busan, and 285 valid copies were analyzed using SPSS 25.0 and AMOS 25.0. In the relationship between variables, collective efficacy was found to have a greater effect on peer pressure among collective efficacy and self-efficacy. And it was found that among self-efficacy, self-efficacy had a greater effect on job satisfaction, and this was collective efficacy due to peer pressure. It is judged that this is due to the professional characteristics and characteristics of the chef, where individual work and skills are important. Also, job satisfaction was found to have a positive effect on job performance. In conclusion, we suggested that these two dimensions of efficacy should be studied together and used in human care programs.

This study aims firstly to examine whether adolescents' life satisfaction influences their fandom activities, then to analyze whether the influences of ego resiliency and peer relations on fandom activities vary by adolescents' life satisfaction and how, if they do, and finally, using multi-group analysis, to identify whether there are gender differences in their fandom activities. The results are as follows: Firstly, as adolescents' life satisfaction is lower, their involvement into fandom activities are increased. Secondly, peer relations and ego resiliency has different relations to fandom activities, that is the former have indirect impact on fandom activities. Ego resiliency has both direct and indirect influence on fandom activities, that is adolescents who have higher ego resiliency participate more actively into fandom activities and this influence is mediated by life satisfaction. Finally, the degree of participation into fandom activities depends of adolescents' gender, that is girls involve in fandom activities more actively. One consistent finding of this study is that fandom activities are negatively related to life satisfaction.
