The purpose of this study was to investigate variables which have an influence on young children's peer interactions. The data of 966 4-year-old children and their parents and class teachers were extracted from the 5th Panel Study on Korean Children in 2012 by Korea Institute of Child Care and Education. The data were analyzed by means of ANOVA, Pearson's coefficient and multiple regression. The results were as follows: First, boys' play disruption and play disconnection were higher than girls', and girls' play interaction was higher than boys'. Second, sociability and activity of temperament, and teacher-child interaction were related to peer disruption. Third, teacher-child interaction and sociability of temperament significantly affected play interaction. Controlling parenting behavior of the mother was positively related to peer interaction in girls. Fourth, teacher-child interaction, sociability and emotionality of temperament significantly affected play disconnection. Social parenting behavior of the father was negatively related to play disconnection in boys. Lastly, teacher-child interaction was the clearest indicator for young children' peer interactions. These findings suggested a potential role of the teacher in young children's peer interactions.

Peer to Peer Networks play an increasing role in today's networks, also it's expected that this type of communication networks evolves more in the future. Since the number of users that is involved in Peer to Peer Networks is huge and will be increased more in the future, security issues will appear and increase as well. Thus, providing a sustainable solution is needed to ensure the security of Peer to Peer Networks. This paper is presenting a new protocol called Malicious Trust Managers Identification (MTMI). This protocol is used to ensure anonymity of trust manager, that computes and stores the trust value for another peer. The proposed protocol builds a secure connection between trust managers by using public key infrastructure. As well as experimental testing has been conducted to validate the proposed protocol.

Objective: This study explored the mediating effects of language development on the influences of young children's media use on positive and negative peer interactions. Methods: The data came from the 2013 Panel Study on Korean Children (N = 1,215) and were analyzed to assess the mediating effects of media use on positive and negative peer interactions, using SEM with the bootstrapping method by means of SPSS 21.0 and AMOS 20.0. Results and Conclusion: The results show that increased media use affects positive and negative peer interactions through language development. This indicates that, while media use does not directly affect positive and negative peer interactions, it appears to increase the difficulty of developing language ability; as the language development worsens, undesirable peer interactions may develop. Thus, language development seems to play an important mediating role between media use and peer interactions. Theoretical and practical implications are discussed.

The purpose of this study was to investigate the mediating effects of young children's playfulness between the children's peer competence and their mothers' play beliefs. For this study, 160 mothers and 160 children aged 4-5 years who were in kindergarten and daycare centers in Area J were selected. The collected data were analyzed based on correlation and mediation using SPSS Statistics. The research results are as follows. First, as a result of analyzing the relationship between the young children's peer competence and playfulness and their mothers' play beliefs, there was a statistically significant positive correlation between a mother's play-support beliefs and their children's peer competence and playfulness. On the other hand, the relationship between a mother's learning-support beliefs and her child's peer competence and playfulness was not significant. There was a significant positive correlation between playfulness and peer competence in the young children. Second, as a result of verifying the mediating effect of the children's playfulness in the relationship between their mothers' play-support belief and the children's peer competence, we found that playfulness has a partial mediating role.

The effects of conflicted teacher-child relation on conflicted or passive peer interaction and a moderation effect of mothers' interpersonal relation satisfaction on the associations were assessed. Children from 2- to 6-year-olds (184 girls, 185 boys) mostly from middle socioeconomic-status urban community in Korea and their teachers and mothers participated. Conflicted teacher-child relation predicted conflicted peer interaction but not passive peer interaction. Children, whose relationship with teachers were conflicted, engaged in conflicted play with peers more often than children who were in less conflicted relationship with the teachers. Teachers who were in conflicted relationship with the children, perceived the children having conflicted interaction with peers more often, if mothers of the children were less satisfying in relationship with significant others, especially boys. Children, whose mothers are in less satisfying interpersonal relation with others, were more passive in peer interaction than children whose mothers are in more satisfying interpersonal relationship.

This study examined the influences of children's playfulness and teacher-child interactions on their peer interactions, and investigated whether teacher-child interactions had any moderating effects upon the relation between child playfulness and peer interactions. The participants of this study were 240 children in fourth year classes in child care centers in Seoul and Gyoung-gi province and 24 of their teachers. In order to measure the research variables, the Korean version of PIPPS(Pen Interaction Peer Play Scale) by Choi and Shin(2008), the Children's Playfulness Scale(Barnett, 1991), and the modified version of the Caregiver Interaction Scale(Arnett, 1989) were used. The data were analyzed by means of descriptive statics, Pearson's correlations, and hierarchical regression analysis. The results indicated that children's playfulness and teacher-child interactions had significant effects on their peer interactions. Especially, the teacher-child interactions were related to the play disruption and the play disconnection of peer interactions. In addition, teacher-child interactions moderated the effect of children's social spontaneity(children's playfulness) on their play disconnection(peer interactions). The results have some implications for the role of teacher-child interactions in peer play interactions and a range of prevention efforts.

Purpose: The purpose of this study was to explore about 2-year-old infants' attachment security to a child care teacher and peer play process through a case study. For this purpose, the attachment security was assessed with attachment Q-set to 2-year-old five infants at a day care center in Seoul. Participants of this study are four infants included two infants attached securely to their child care teacher and two infants attached insecurely to their child care teacher. Methods: Participant observation was conducted from April 12 to July 19 in 2018 through 36 observations in free play activities. The Data collected from the transcriptions of video shoots and teachers' interviews, child care plans, and reflexive journal was analyzed and interpreted. Results: The main results of the research were as follows: The beginning of peer play, when infants invited their peers to play, secure attachment infants selected suitable play partners and asked for a specific play behaviors. However, insecure attachment infants invited unsuitable play partners and asked uncertainly play actions to peers. In addition, when infants entered in-progress play, secure attachment infants understood the context of play but insecure attachment infants did not understand the context of play. In the progress of peer play, secure attachment infants cooperated with peers, shared play objects, but insecure attachment infants did not cooperate complementally with peers and express only their opinions. As well, insecure attachment infants could not play harmoniously without child care teacher's interventions. In the end of the peer play, secure attachment infants finished in collaboration with peers but insecure attachment infants failed to finish with the peers and was turned into play with the child care teacher because of peer conflict. Conclusion/Implications: This study has implications for basic resources to think about the role of child care teachers by helping them understand about the relation 2-year-old infants' attachment security to them and peer play process.

The aim of this study is to examine the pathways from attachment to children's psychological well-being in addition to the mediating role of children's ego-resilience and peer support. The participants, 297 fifth and sixth grade students from Seoul and other cities, completed questionnaires on attachment, ego-resilience, peer support and psychological well-being. Data were analyzed by mean, standard deviation, Pearson's correlation coefficients, factor analysis, and path analysis. The findings are as follows. Attachment didn't appear to directly influence children's psychological well-being, but showed a number of indirect effects in two ways. First, attachment indirectly affected children's psychological well-being by ego-resilience as a simple form of mediation. Second, attachment influenced children's psychological well-being through children's ego-resilience and peer support as a dual mediation. Ego-resilience demonstrated the strongest effect on psychological well-being among all the factors examined. These results highlight the way in which children's personal internal resources play an important role in the pathways from attachment to their psychological well-being.

In the paper, an algorithm fitted to P2P system was proposed by improving Kerberos which is an algorithm for mutual authentication. To keep the role of Kerberos and minimize load to server, the proposed algorithm imposed the server role of ticket recognition to the opposite peer. Using this method, the number of sewers as ticket recognition server was averted and function of server for authentication was minimized so that server load was mininized. The proposed algorithm enables the server to play the minimum of the role and to perform strong mutual authentication, while imposeing on the peers the role of authentication. To make suitable to P2P system, trial number oriented authentication limit was given, not time-oriented authentication expiration time. In the paper, a new P2P system was designed using this algorithm.

Objective: This study examined the relations between maternal meta-emotion philosophy, child interpersonal problem solving, and peer competence among children aged 4-5 and their mothers and teachers. Methods: A total of 54 children from 24 kindergartens were assessed on their interpersonal problem solving and peer competence. Their mothers reported on meta-emotion philosophy. Their teachers were assessed on child peer competence. Results: The major findings of this study were as follows. First, maternal meta-emotion philosophy, child interpersonal problem solving, and child peer competence showed positive correlation patterns. Second, child interpersonal problem solving and peer competence was found to be influenced by maternal child-directed meta-emotion philosophy but not by maternal self-directed meta-emotion philosophy. Conclusion: Findings highlight the importance of maternal meta-emotion philosophy and that their emotion socialization play a significant role in identifying the mechanisms leading to child social cognitive ability and social adjustment. Furthermore, these results could lead to important basic studies in developing parent/teacher education programs.
