Objective: The aim of this study was to examine the mediated effect of teacher-infant relationships between teacher efficacy and infant's adjustment to child care centers. Methods: A total of 137 child care teachers that lived in Gwangju and Jeollanamdo participated in this study. They were asked to answer two survey questionnaires for two infants. The data were analyzed using analysis of frequency, Pearson's correlation coefficient, and hierarchical multiple regression analysis. Results: The main results are as follows. First, teacher-infant relationships partially mediated the relationship between teacher efficacy and two sub-factors (prosocial behavior and day work adjustment) of adjustment in child care centers. Unlikely as it was, several sub-factors such as positive emotion, peer adaptation, and self-strength were fully mediated by teacher-infant relationships. Conclusion: The present study suggests that it is necessary to improve teacher-infant relationships with teacher efficacy in order to improve infants' adaptation to daycare. In addition, it should be understood that the structural relationship of the influence factors is different depending on the sub-factors of the child care adjustment.

The purpose of this study was to understand the influence of personality trait information on young children's perception of initial attraction in peer relationships. The sample consisted of 90 children of three to five years of age in South Korea. Children were presented with an inductive inference task where they had to make inference of a target character's preference on novel-play and prosocial act based on trait labels (smart-not smart, outgoing-shy, nice-mean) and perceptual (toy) similarity information of two test characters. Children showed difference in their use of trait information depending on the perceptual similarity information, trait valence, and inference question with age. This result provides initial support that not only do young children understand the significance of trait in peer attraction but also know when trait label is more informative to use to infer others depending on the situation.

Self-efficacy is an important variable determining adolescents' behavior. This study was designed to develope a program for improving teens' self-efficacy. The goal of this program was as follows: (1) to improve self-efficacy by enlarge self-knowledge through in- depth search of one's own inner world, (2) to correct one's inferiority impeding one's inner growth, (3) to improve self-efficacy in family relationship, peer relationship, and academic achievement areas. This program consisted of total 6 sessions, supplemented with interpersonal relationships regarding positive family functioning and the impact of peer groups which were found out in recent researches. Specific strategies such as verbal persuasion, mastery experience, vicarious experience and affective arousal were used.

This study investigated the influence of peer friendliness, conflict, and collaboration on children's problem solving performance. Eighty-two preschool children (41 pairs) filled out the Friendship Assessment Inventory and participated in 3 problem-solving sessions using the Tower of Hanoi. Results showed that just working together does not improve children's problem solving performance. The degree of friendliness children have for each other has a significant effect on their problem solving performance. The children who worked with more friendly peers were more collaborative and were better problem solvers than those who worked with less friendly peers. This study suggests the importance of the relationship between interacting peers on problem solving performance.

A multitude of overlay network designs for resilient routing, multicasting, quality of service, content distribution, storage, and object location have been proposed. Overlay networks offer several attractive features, including ease of deployment, flexibility, adaptivity, and an infrastructure for collaboration among hosts. In this paper, we explore cooperation among co-existing, possibly heterogeneous, overlay networks. We discuss a spectrum of cooperative forwarding and information sharing services, and investigate the associated scalability, heterogeneity, and security problems. Motivated by these services, we design Synergy, a utility-based overlay internetworking architecture that fosters overlay cooperation. Our architecture promotes fair peering relationships to achieve synergism. Results from Internet experiments with cooperative forwarding overlays indicate that our Synergy prototype improves delay, throughput, and loss performance, while maintaining the autonomy and heterogeneity of individual overlay networks.

This study was designed to examine the casual relationships among trust evaluation factors, trust, customer satisfaction, and re-use intention in the P2P file sharing service. We applied structural equation model to test the hypotheses and research model. As a result of this study, trust evaluation factors affect trust and customer satisfaction and both of trust and customer satisfaction affect re-use intention respectively and significantly. Also trust affects customer satisfaction significantly. Specifically, trust was empirically confirmed as one of the important factors preceding customer satisfaction and re-use intetion in the P2P file sharing service. Therefore, this study shows that trust is important factor that P2P companies have to emphasize to raise user satisfaction and performance.

The social dramatic play of seventeen five-year-old children was videotaped and transcribed for analysis of Intersubjectivity and play role types. The teachers of the children rated children's social competence. Results showed that children's Intersubjectivity in social dramatic play was related to their play role types and peer competence. Children with a high level of Intersubjectivity play leading roles during social dramatic play and were rated as socially competent by their teachers. The results were discussed from the Vygotskian perspective. Implications for early childhood teachers and suggestions for future studies were provided.

Subjects of this study were 621 children selected from 5th and 6th grades of elementary schools in Pusan. Factors associated with parents and peers varied by type of peer maladjustment(aggressive type and withdrawn type, compared with a control group). Particularly, the level of factors associated with peers varied from the control group by peer maladjusted types(aggressive types and, withdrawn types). Causal relationships of parents' rejection, victimization, negative representation by parents and by peers on child？s maladjustment varied by behavior types. Negative representation of peers had a direct effect only on withdrawal. On the other hand, negative representation of peers had no effect on aggression. Victimization had a first total effect on both withdrawal and aggression.

Over seven years, BTS have organically embedded consistent mental health messaging and modelling of various mental health modalities, representing innovation within mental health discourse, within and outside the pop and K-pop culture and fandom. Their personal and artistic journeys have resulted in songs, imagery, and relationship dynamics within the group and within and between their fans ARMY, that organically model behaviours associated with mental health therapeutic modalities and normalize the discussion of mental health and well-being. This practice is vitally important in the effort to end stigma and encourage mental health well-being and recovery. BTS's authenticity establishes empathy with their audience ARMY and increases their ability to deliver these messages effectively. This includes fostering the creation of a peer support community within the group that extends to their fanbase ARMY, and from which fan-created mental health programs have emerged. BTS's innovation will be explored by examining content creation throughout their career, illustrating their consistent and organic messaging, culminating in overt and conscious mental health content in their latest album BE, which was released three weeks after the initial paper was presented, and provides proof of concept.

This study investigated the effect of housing poverty in childhood on adolescents' subjective well-being. Specifically, this study examined whether the major factors that have been known to affect adolescents' well-being (i.e., family relationships, peer relationships, school adjustment etc.) mediated the relationship between housing poverty and adolescents' well-being. And then this study aimed to present an empirical evidence for establishing policies against housing poverty in order to enhance adolescent's subjective happiness. Data were derived from the $1^{st}$, $4^{th}$, and $7^{th}$ surveys of the Korea Welfare Panel Study(KOWEPS), and the sample included. 512 high school children in the $7^{th}$ survey. This study utilized structural equation modeling. Housing poverty was measured by the sub-minimum standard housing condition and the household's burden of housing expenditure. Family relationship, as a mediator, was measured by parental involvement in education, parental monitoring, and family conflicts. Another mediator, school adjustment was measured by school environment and school bonding, and the last mediator, peer relationship was measured by friend attachment and peer attachment. The results showed that housing poverty had significant negative effects on the adolescents' subjective well-being. The sub-minimum standard housing condition with inadequate size and facilities negatively affected adolescents' relationships with family directly and subjective well-being indirectly. In addition, the negative family relationships due to the sub-minimum standard housing condition negatively affected adolescents' subjective well-being through school adjustment and peer relationships. The greater the proportion of income a household spends on housing expenditure, the less likely for adolescents to report positive well-being. The sub-minimum standard housing condition had indirect effects through family relationships, whereas the household's housing expenditure directly affected adolescents' subjective well-being. This study suggested the necessity of interventions to alleviate housing poverty for adolescents' families and lays the groundwork for housing poverty policies in Korea.
