유무선 인터넷 기술의 발달로 인해, 네트워크 전반에 걸쳐 산재해 있는 개인 정보에 대한 공유 및 교환에 대한 요구가 점차로 증가하고 있다. 본 논문에서는 이동에이전트 기반의 peer-to-peer(P2P) 네트워킹을 위한 새로운 기법이 설계되고 구현된다. 설계된 시스템은 이동에이전트를 사용함으로써, 냅스터 및 그 누텔라로 대표되는 기존의 혼합형 P2P와 순수형 P2P에서 발생하는 문제점들을 보완시킨 새로운 기법이며, 혼합형과 순수형 모두에 적용이 가능하다. 또한 분산 정보 공유 및 교환을 위한 응용 개발의 용이함을 위해 다양한 고급의 AH들을 제공하고 있다.

Objective: The purpose of this study is to investigate the moderating role of Ego-Resilience between Peer Attachment and Mobile Phone Dependency in late adolescence. Methods: The participants were 2056 third year high school adolescents (1,041 boys and 1,015 girls) from the Korea Youth Panel Study (KYPS), a national representative of Korean Children and adolescence. Hierarchical Regression was used for data analysis. Results: First, the correlation between peer attachment, ego-resilience and mobile phone dependency were all significant. Second, ego-resilience takes the role of moderator for mobile phone dependency. In detail, ego-resilience relieves the mobile phone dependency caused by 'peer relationships' or 'conflict in peer relationships. Conclusion/Implications: Ego-resilience was found to control the relationship between peer attachment and mobile phone dependency. Therefore, in order to lower the dependence of mobile phones in adolescents with low peer attachment, a program that can enhance ego-resilience is needed.

This study sought to examine the effects of child-parent attachment and its concordance with children's peer status. The subjects were 110 5-6 year old kindergarteners (48 boys & 62 girls) and they were asked to respond to the Attachment Story Completion Task by Bretherton & Cassidy (1990) and the peer rating scale by Asher, Singleton, Tinsley & Hymel (1979). Our results indicate that the secure mother-child and father-child attachment groups had higher peer status than the insecure attachment groups. The insecure-avoidant groups had the lowest peer status. Young children who were securely attached to both parents and at least one parent had higher peer status than who were found to be insecurely attached to both parents. The implications for parent education for enhancing peer relations were also discussed.

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 relations between friendships peer aggression and victimization by peers were examined with a sample of 426 second-grade junior high school students(210 boys and 216 girls) Data were collected using questionnaires regarding friendship(number of friends and presence of a best friend) peer aggression and victimization by peers. The number of friends was significantly related to peer aggression both in boys and girls indicating that the more friends they had the less peer aggression they showed. Peer aggression didn't vary as a function of the presence of a best friend. The number of friends was also significantly related to victimization both in boys and girls. The more friends they had the less victimization they experienced. Victimization varied as a function of the presence of a best friend only in adolescent boys in which those having a best friend were rated by peers to experience less victimization, Victimization was related to peer aggression both in boys and girls. T e more victimization they experienced the more peer aggression they showed.

The purpose of this study was to examine the mediation effect of peer attachment on the relationship between children's depression and mother attachment. The respondents in this study were 697 school aged children attending elementary schools in Daegu and Gyeongbuk Province. Questionnaires, which required self-reporting by children, were used to investigate mother attachment, peer attachment and depression. The collected data were analyzed by Structural Equation Modeling(SEM) and Sobel test using AMOS 8.0, and SPSS 15.0. The results of the study were as follows. Structural Equation Modeling(SEM) revealed that peer attachment partially mediated the relationship between mother attachment and depression. First, mother attachment had a direct effect on peer attachment. Second, peer attachment had a direct effect on depression. Third, mother attachment had an indirect effect on depression as a mediated effect of peer attachment.

This study examined the effects of mother's support and peer acceptance on children's domain specific self-esteem and the moderating effects of best friend's support. The subjects were 272 $4^{th}$ and 349 $8^{th}$ grader in Chin-ju. Data were analyzed by the SAS/PC+ program, including Cronbach's ${\alpha}$, Pearson's correlation, multiple regression and two-way ANOVA. Findings were that peer acceptance had a higher influence on academic-general self, peer-related self, physical-appearance self, personality self and physical-competence self than did mother's support. Mother's support had a higher influence on home self than did peer acceptance. Best friend's support and mother's support interacted with children's physical-appearance self and physical-competence self. Best friend's support and peer acceptance interacted with student's peer-related self.

The purpose of this study was to investigate the effects of children's individual characteristic on peer acceptance. The subjects were 234 6th grade elementary school children in Kwangju, Korea. The Questionnaires were used to collect the data on peer acceptance and social behavioral trait, physical attractiveness, demographic variables and the school achievement grade assessed by their teachers. The results were as follows : 1. Peer acceptance score, school achievement grade, prosocial behavior score, appearance score and physical attractiveness tend to be above the median scores. Aggression behavior score and withdrawal score tend to below the median scores. 2. The effect of individual characteristic variables on the peer acceptance found all significantly. 3. The influence of prosocial behavior, physical attractiveness, withdrawal behavior, aggressive behavior and school achievement grade on peer acceptance were found significantly. Prosocial behavior was the most influential variable on peer acceptance.

This study analyzed variables associated with peer competence of negelcted children. Participants were made up of 180 preschoolers and their mothers. Neglected children's peer competence was measured by the Peer Competence Scale(Park & Rhee, 2001) and data were subjected to descriptive analysis, Pearson's correlation, and multiple regression analysis. Results showed that neglected children's peer competence was partly associated with the child's temperament and emotional regulation, parenting styles and involvement strategy, and teacher-child relationship. In particular, closeness in teacher-child relationship was the strongest predictor for both children's peer competence in leadership and sociability. Furthermore, a child's ability to regulate emotion was the strongest predictor of their peer competence in prosocial environments.
