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.

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.

This study examined the relation between parent attachment, peer rejection, and friendship in 768 eighth grade students and victimization by peers in early adolescence. The subjects reported on father attachment, mother attachment, and victimization. Victimization was also rated by peers and teachers. The subjects were assessed on peer rejection and friendship(number of friends and presence of a best friend). The results indicated that (1)Father attachment and mother attachment were negatively related to self-reported victimization; (2)Peer rejection was positively related to victimization; (3)The number of friends was negatively related to victimization rated by peers, and victimization rated by peers varied as a function of the presence of a best friend only for girls; (4)The relation between parent attachment and victimization was not mediated by peer rejection or friendship, which indicated that parent attachment had a direct influence on victimization.

It is necessary to analyze the character that are a key element of the story in order to analyze the story. Current character analysis methods such as Character-net and RoleNet are not sufficient to classify the roles of supporting characters by only analyzing the results of the final accumulated stories. It is necessary to study the time series analysis method according to the story progress in order to analyze the role of supporting characters rather than the accumulated story analysis method. In this paper, we propose a method to classify helpers as a mentor and a best friend through 3-D visualization of Character-net and evaluate the accuracy of the method. WebGL is used to configure the interface for 3D visualization so that anyone can see the results on the web browser. It is also proposed that rules to distinguish mentors and best friends and evaluated their performance. The results of the evaluation of 10 characters selected for 7 films confirms that they are 90% accurate.

The purpose of this study is to examine the moderating effects of protective factors on the relations between deviant peer's influences and delinquent behaviors in adolescence. To investigate the moderating effects, simple slope and region of significance test based on multiple linear regression(MLR) model were used. This study used data from wave 1-2(2003-2004) of the Korea Youth Panel Survey(KYPS). Results showed that for female adolescents, self-esteem, parent monitoring, and attachment to parent moderated the link between best friend's deviancy and delinquent behaviors. For male adolescents, however, best friend's deviancy and protective factors didn't show any significant moderating effects. These results help clarify the conditions under which exposure to deviant best friends can influence delinquent behaviors in adolescence. Practice and policy implications as well as further research topic were discussed to aid the search for highly effective preventive and treatment interventions.

The purpose of this study was to investigate the moderating effects of a size of the friendship network and quality of friendship on the associations between mutual antipathy and maladjustment. The subjects were 678 fifth- and sixth-grade primary school children who were recruited from a public school in Bucheon City. The Peer Nomination Inventory was used to assess mutual antipathy, peer victimization, social withdrawal, aggression, and the friendship network. The children were given a classroom roster and asked to nominate up to three classmates who fit each description. Additionally, the children reported the quality of their friendships using the Friendship Quality Scale. Each child was asked to indicate his or her one best friend and rate how accurately a sentence describe done of their best friends on the scale. The results revealed that the friendship network and friendship quality significantly moderated the relationships between mutual antipathy and social withdrawal, and peer victimization. The magnitude of the association between mutual antipathy and social withdrawal was not significant for large friendship networks and high quality friendships. Although mutual antipathy was significantly associated with peer victimization, the association was stronger at lower levels than at higher levels of the friendship network and quality. However, there was no moderating effect of the friendship network and quality on the association between mutual antipathy and aggression. A large friendship network and high quality friendship could be protective factors among those who have mutual antipathy in peer groups.

This study investigated associations between attachment and friendship. This study also examined the mediating effects of empathy on the association between two variables. Participants consisted of $4^{th}$ to $6^{th}$ grade elementary school children including 173 boys and 141 girls. Two elementary schools were located in Seoul and Bucheon. Children participated in a peer nomination interview. They nominated their three most liked peers. Children's responses to the best friend of the peer nomination identified the children's best friends. A Friendship Quality Scale measured children's positive friendship quality and friendship satisfaction. Children completed the Inventory of the Parent and Peer Attachment Scale that assessed maternal and paternal attachment. In addition, they completed a children's version of the Empathy Quotient that measured empathy. Pearson's correlation and Structural Equation Modeling were used to analyse the data. The results indicated that attachment had a direct influence on friendship network. Children who had the high levels of attachment security had large friendship network. However, attachment did not have a significant effect on friendship quality. Moreover, empathy had mediating effects on the association between attachment and friendship quality as well as the friendship network. The results of this research highlight the importance of attachment and empathy on children's friendship.

This study investigated the moderating effects of the number of friends and quality of friendship on the associations between withdrawal and loneliness as well as withdrawal and social anxiety. The subjects were 678 of fifth and sixth grade primary school children recruited from a public school in Bucheon city. A peer nomination inventory was used to assess withdrawal. Children were given a classroom roster and asked to nominate three classmates who fit each description. Children reported the quality of their friendships using the Friendship Quality Scale. Each child was asked to indicate his or her one best friend and rate how accurately a sentence describe done of their best friends on the scale. In addition, children completed questionnaires to assess the loneliness and social anxiety. The results revealed that the association between withdrawal and loneliness was not significant for children who had the large number of friends and high quality friendship. The association between withdrawal and social anxiety was stronger for the children who had the lower levels of friendship quality. However, there was no moderating effect of the number of friends on the association between withdrawal and social anxiety. These results imply that the large number of friends and high quality friendships could be protective factors for children who are withdrawn.

The purpose of this study is to explore the relationships that a popular three year old child has with other children and teacher. One popular child was selected among thirteen children using peer-nomination method and participated in this study. During free choice play time, the popular child's various activities and interaction patterns were observed and analyzed. The popular child in this study had a steady intimate friendship with his best friend most of the time. However, he showed a tendency to behave as he pleased and give orders to other children who he was not in a close relationship with. He did some deliberate and premeditated acts to get praise and love from his teacher. The teacher's compensations also reinforced his intentional actions.

Friendship network characteristics, friendship quality, and popularity status were examined for 298 first and third graders(M age=7 yrs., 3 mo. and 9 yrs., 2 mo.). Children provided friendship nominations and responded to the Friendship Quality Scale(Rhee & Koh, in press). Results indicated that 3rd graders had larger friendship networks and more supportive friendship than 1st graders, and girls reported more reciprocal friends and more supportive friendships than boys. The best predictor for friendship satisfaction was a reliable alliance. The higher the reciprocity in friendship choice, the higher the perception of friendship functions and satisfaction. Unpopular children were less likely than popular children to have a reciprocal friend, although friendless children were found in both groups.
