This study examined the moderating and mediating effects of teacher-child conflict relationship among child's language ability, emotional regulation and peer victimization. The participants were 152 children(77 boys, 75 girls) and 14 preschool teachers. The teachers completed rating scales to measure the child's emotional regulation, peer victimization and teacher-child relationship. Child's language ability was assessed by researcher using PRES(Preschool Receptive-Expressive Language Scale). The collected data were analyzed using Pearson correlations and hierarchical multiple regressions. Results showed that peer victimization was related to child's language ability, emotional regulation and teacher-child relationship. Hierarchical aggression analysis indicated that the interaction of child's receptive language ability and teacher-child conflict relationship predicated peer victimization. Child's language ability, whose demonstrated a lower teacher-child conflict relationship, was significantly with peer victimization. In addition, the association between a child's emotional regulation and peer victimization was partially mediated by teacher-child conflict relationship.

This study examined the effect of parental achievement-oriented expectation on high school students' depression and verified the mediating effect of peer relations on relations. Data were derived from the 7th wave (2016) of Korean Children and Youth Panel Survey (KCYPS), and 1,979 high school students were included. Descriptive statistics analysis, correlation analysis, multiple regression analysis, and a Sobel test were conducted using STATA. The main results were as follows. First, male adolescents perceived higher parental achievement-oriented expectation, lower peer relations, but lower depression than female adolescents. Second, parental achievement-oriented expectation was negatively related to adolescent peer relations but positively related to adolescent depression. This implies that adolescents whose parents have a higher level of achievement-oriented expectation have lower level of peer relations and higher level of depression. Third, adolescents' peer relations significantly mediated the relation between parental achievement-oriented expectation and high school students' depression. The result of Sobel test supported the significance of the mediating effect. The results highlighted a negative impact of parental achievement-oriented expectation on adolescents' mental health, and addressed how parental achievement-oriented expectation affects adolescents' depression by showing an important mechanism of peer relations, which was missed in previous research.

Recent years have witnessed an increasing number of alternative school students in Korea. However, few studies have empirically examined these students' school adjustment and peer relationship skills. To address this gap in the literature, this study examines the effects of individual characteristics, family characteristics and peer relationship skills on these students' school adjustment. Four aspects of school adjustment were measured as dependent variables. These four aspects included peer relationship adjustment, relationships with teachers, school environment adjustment, and schoolwork attitude adjustment. The peer relationship skills included three components, namely initiative, mutual closeness, and order awareness. Data were collected from 323 alternative middle and high school students through a structured questionnaire. The statistical analysis methods included descriptive statistics and a hierarchical regression analysis using SPSS WIN 19.0. According to the results, peer relationship skills as well as family background characteristics, including the age of the father, the education level of the father, the family economic level, and the number of close family members, had significant effects on school adjustment. The results highlight the importance of peer relationship skills for these students' successful school adjustment and have important policy and theoretical implications.

The purpose of this study was to analyze the teacher-child relationship as it is self-conceived by teachers in regards to children's peer-competence and self-regulation and to also examine how the teacher-child relationship affects peer-competence and self-regulation. 17 teachers were surveyed using the Student-Teacher Relationship Scale, Peer-Competence Scale and Self-Regulation Scale in regard to approximately 270 children (aged 4-5 years old). Our results indicated that the pro-sociality, sociality, and leadership qualities of child peer-competence correlated positively with the friendliness of teacher-child relationships but correlated negatively in cases of conflicts within the teacher-child relationship. The factors of self-appraisal, self-determination and behavior inhibition of child self-regulation were found to be positively related with the friendliness of teacher-child relation but related negatively with presence of the conflict within the teacher-child relationship. It was also found that sociable and self-determinative children tended to be on more friendly terms with teachers.

In this paper, we propose virtual direction multicast (VDM) for video multicast applications on peer-to-peer overlay networks. It locates the end hosts relative to each other based on a virtualized orientation scheme using real-time measurements. It builds multicast tree by connecting the nodes, which are estimated to be in the same virtual direction. By using the concept of directionality, we target to use minimal resources in the underlying network while satisfying users' quality expectations. We compare VDM against host multicast tree protocol.We simulated the protocol in a network simulator and implemented in PlanetLab. Results both from simulation and PlanetLab implementation show that our proposed technique exhibits good performance in terms of defined metrics.

The purpose of this study was to analyze music therapy students' experience of peer supervision as supervisee. A total of 17 participants in a university in Seoul, participated two times in structured dyadic peer supervision with a different student. In-depth, semi-structured interviews with the students were conducted and content analysis was used for analyzing the data. The results showed that peer supervision was recognized as an important technique as students experienced an accepting and supportive emotional climate that increased their motivation in terms of their professional growth. However, the students also experienced anxiety and dissatisfaction when they could not get a definitive answer from their peer or their peer could not solve their problem. The structure of peer supervision could help the participants by facilitating the process, providing directions, and promoting interaction between peer. This study is significant that it provides actual content in music therapy students' experiences as a supervisee, and enables students to apply peer supervision to their professional growth.

Peer-to-Peer (P2P) networks are attracting considerable research interest because of their scalability and high performance relative to cost. One of the important services on a P2P network is the streaming service. However, because each node in the P2P network is autonomous, it is difficult to provide a stable streaming service on the network. Therefore, for a stable streaming service on the P2P network, a fault-tolerant scheme must be provided. In this paper, we propose two new node selection schemes, Playback Node First (PNF) and Playback Node first with Prefetching (PNF-P) that can be used for a service migration-based fault-tolerant streaming service. The proposed schemes exploit the fact that the failure probability of a node currently being served is lower than that of a node not being served. Simulation results show that the proposed schemes outperform traditional node selection schemes.

Peer conflicts between school-aged children were observed to examine differences in conflict resolution strategies according to children's sex, peer status, and friendship. One hundred and forty eight dyads in 4th grade were selected for the study. The dyads' interactions in a small room while playing a Domino game were videotaped. Strategies the children used to resolve peer conflicts were analyzed by frequencies, and ANOVAs. School-aged children used reasoning and insistences to the partners frequently to resolve conflicts. Conflict resolution strategies were different by children's status among peers. Popular children used reasoning and listening more frequently. Rejected children used standing firm, behaving aggressively, ignoring, and withdrawing more frequently, and explaining and listening less frequently. Rejected children, especially rejected boys, used aggressive strategies more frequently.

This study examined the relationships of children's peer competence with maternal parenting styles and children's emotion regulation. Thirty boys and thirty-one girls in 3 to 6 years of age and their mothers participated. Mothers responded to Parental Acceptance-Rejection Questionnaire(Hwang, 1997), and teachers rutted each child using Peer Competence Scale(Park & Rhee, 2001) and Emotional Intelligence Scale(Lee, 1997). Mothers'acceptive parenting style and children's abilities to regulate emotion were positively related to children's peer competence. Children's emotion regulation rather than mothers' parenting styles predicted peer competence.

In this paper, we propose two new routing schemes for double-layered peer-to-peer systems; a shorter-lower mobility routing scheme and a reverse path routing scheme. The shorter-lower mobility routing scheme first chooses shortest routing paths among possible routing paths and selects the path associated with the relay peer who has lower mobility to improve the reliability of the system. The reverse path routing scheme carries out unicasting (instead of multicasting) based on the reverse path information that can be obtained during the initial file search to further reduce network traffic. The experimental results showed that a double-layered peer-topeer system with the proposed hybrid scheme improved the reliability of the system about 1.5% over the hop count scheme and reduced network traffic by about 0.5% compared to the hop count scheme.
