The purpose of this study was to investigate the relationship between children's popularity and Interpersonal Cognitive Problem-Solving Skill(ICPS). The subjects were 162 children(70 popular, 76 rejected, and 16 neglected children) chosen from 359 children between the age of 5 -6 and 8-9 years of age. The materials were peer nomination measures developed by Moreno(1934 ) and Interpersonal Cognitive Problem-Solving Skill produced by Park, Chan-Ok from IPCS of Spivack(1976). The data were analyzed by 3-way ANOVA popularity (3) ${\times}$ age (2) ${\times}$ sex (2), t-test, and $Scheff\acute{e}$ test. The results were that (1) children's popularity was significantly different by sex, (2) children's ICPS was significantly different by age for boys, (3) there was no significant difference in ICPS by popularity, and (4) there were significant differences in positive negative solution thought.

The purpose of this study was to investigate possible differences in the behavior problems of peer-rejected and peer-neglected children in relation to parent and teacher perspectives. The subjects in this study were 239 children and their parents(fathers:37, mothers: 155. father+mother pairs:47) and 10 teachers in the fifth grade of a public elementary school located in Seoul. The sociometric assessment mothods were positive and negative peer nominations. On the basis of this sociometric assessment. children were assigned to one of 4 categories in degree of popularity:65 popular, 53 average. 62 rejected. and 59 neglected children. Parents and teachers rated child behavior on the Achenbach and Edelbrock Child Behavior Checklist(CBCL) for parents and Teacher's Report Form(TRF) were used. The obtained data were analyzed by one-way MANOVA and Duncan Multiple Range Test. Rejected children were found to exhibit more behavior problems than neglected, popular, or average children. Neglected children, however, did not exhibit more behavior problems than chidren of average status.

This study explored gender differences in social status, acceptance/rejection, perceived popularity, social emotions, avoidance and anxiety by participant roles in bullying situations. Subjects were 215 6th grade children. Instruments were the Participant Roles (Sutton & Smith, 1999), Peer Nomination (Coie & Dodge, 1983 Cillessen & Mayeux, 2004), Social Avoidance and Social Anxiety (Franke & Hymel, 1984) scales. Results showed that more boys than girls were in pro-bullying participant role groups; more girls than boys were in outsider groups. Boy pro-bullies were high in social rejection. Boy defenders were high in popularity and low in social avoidance. Boy outsiders had high social anxiety. Girl victims had low social status, low social acceptance and lowest perceived popularity; they were high in social avoidance and social rejection.

This study investigated whether parental disciplinary practices mediated the status of peer acceptance. From a sample of 420 kindergarteners, twenty were classified as popular children and twenty were classified as rejected children using sociometric assessment and their parents(40 mothers and 40 fathers) were responded to a parental behavior questionnaire Results were as follows: 1. Compared to rejected children, popular children had fathers who participated more actively in child-rearing practices and mothers who were less overprotective in child-rearing practices. 2. Popular children had fathers who were more affectionate and more actively participated in child-rearing practices than mothers were, whereas rejected children had fathers who were more overprotective than mothers were. 3. Reasonable guidance made by parents was uniquely predictive of peer popularity, whereas parental overprotection was the best predictor for peer rejection.

To meet the increased demand of video-on-demand (VoD) services, peer-to-peer (P2P) mesh-based multiple video approaches have been recently proposed, where each peer is able to find a video segment interested without resort to the video server. However, they have not considered the constraint of the server's upload bandwidth and the fairness between upload and download amounts at each peer. In this paper, we propose a novel P2P VoD streaming system, named peer cache adaptation (PECAN) where each peer adjusts its cache capacity adaptively to meet the server's upload bandwidth constraint and achieve the fairness. For doing so, we first propose a new cache replacement algorithm that designs the number of caches for a segment to be proportional to its popularity. Second, we mathematically prove that if the cache capacity of a peer is proportional to its segment request rate, the fairness between upload and download amounts at each peer can be achieved. Third, we propose a method that determines each peer's cache capacity adaptively according to the constraint of the server's upload bandwidth. Against the proposed design objective, some selfish peers may not follow our protocol to increase their payoff. To detect such peers, we design a simple distributed reputation and monitoring system. Through simulations, we show that PECAN meets the server upload bandwidth constraint, and achieves the fairness well at each peer. We finally verify that the control overhead in PECAN caused by the search, reputation, and monitoring systems is very small, which is an important factor for real deployment.

The purpose of this study was to investigate the relationships of home environments, personal factors on prosocial behaviors through analysis on children's sex and age. The data were collected by questionnaire method from 190 elementary school and 102 middle school children in Pusan. The instruments used are the child's prosocial behavior test on the basis of the self report scale by Yang, Jean Sook(1991). Frequency and regression analysis were applied for data analyses. The main results of the study were as follows; (1) Prosocial behaviors were directly influenced by home environments and personal factors on children's prosocial behaviors. Personal factors were stronger than home environments in influencing on children's prosocial behaviors. (2) Girl's prosocial behaviors were influenced by home economic level, parent's educational level, leaderships, the sphere of peer relations, popularity, prosocial behavior experience and maturity of prosocial motive. Boy's prosocial behaviors were influenced by leaderships, the sphere of peer relations, popularity, prosocial behavior experience and maturity of prosocial motive. (3) The effects of home environments and personal factors for prosocial behavior differed accoring to children's age. The more children aged, the less home environment & effective factors influenced.

The various services applied internet have been provided by the rapid development of wireless networks and providing multimedia contents are also increasing. It is caused a number of problems such as increasing of network traffic rapidly. P2P technique is gaining popularity for solving these problems. In particular, P2P technique in a wireless network environment has gained much popularity. Among them, MANET-based P2P techniques has been studied actively. It is not easy to be applied the existing technique as it is due to the dynamic topology and low bandwidth by moving nodes in MANET that is consisted of only mobile nodes. In this paper, we proposed sharing group construction technique for providing a stable connection between mobile nodes and reducing the load of network traffic and overhead of sharing group reconfiguration in order to improve data transmission performance between mobile nodes. The sharing group member nodes applied virtual sharing group generation technique with neighboring nodes of 1-hop distance in order to reduce traffic for file sharing. We performed comparative experiments with DHT technique to evaluate the performance of the proposed technique in this paper and the excellent performance is confirmed through experiments.
