In a group of 353 elementary students, the present study examined the moderation effects of prosocial behaviors and social competence in the relations between overt/relational aggression and peer status (social preference and perceived popularity). The results indicate that both overt aggression and relational aggression lowered social preference regardless of gender. Prosocial behaviors and social competence did not buffer the negative influence of aggression on social preference. Among boys, overt aggression was a significant predictor of increased perceived popularity. Although inconsistent, relational aggression also predicted boys' perceived popularity. However, among girls, relational aggression, not overt aggression, was associated with perceived popularity. The moderation effects of prosocial behaviors and social competence were significant only among boys. In other words, boys' aggression, although it lowers social preference, contributes to their social influence and dominance when it is effectively combined with positive characteristics. It is necessary to develop new intervention strategies which reflect the adaptive function of aggression within peer groups.

The purpose of this study was to investigate the relationship between sociometric popularity (like-most nomination and like-least nomination) and perceived popularity (most-popular nomination and least-popular nomination ) and to examine the relationships between adolescent aggression (overt, relational, and not prosocial behavior) and each of the popularities. The 377 subjects were selected from first and second graders of middle and high schools. The results of this study were as follows: 1) Sociometric popularity is significantly correlated with least-popular nomination, but not with most-popular nomination. 2) Adolescent aggression is negatively correlated with socimetric popularity, but positively associated with perceived popularity. 3) Sociometric popularity is negatively associated with aggression for only girls, but perceived popularity is positively associated with aggression for both boys and girls. 4) Sociometric popularity is negatively associated with aggression for only middle school students, but perceived popularity is positively associated with aggression for both middle and high students.

The major purpose of this study was to explore mediating effects of narcissism between perceived popularity and aggression in adolescence. The subjects who participated in this study were 783 middle school students based in Busan. The results indicated that perceived popularity and narcissism were positively correlated to overt and relational aggression. The effects of perceived popularity on overt and relational aggression was perfectly mediated by narcissism. Athletic and fighting abilities were more important for boys' perceived popularity, but active involvement in social activity and appearance were more important for girls' perceived popularity. It was further observed that having a good sense of humour was the most important determinant of perceived popularity, irrespective of gender.

This study examined the development of children's perceptions of popular and unpopular peers. Subjects were 784 children in kindergarten, $2^{nd}$, $4^{th}$, and $6^{th}$ grades. Research findings were that : (1)socio-metric popularity and perceived popularity correlated positively with athletic ability, academic ability, and prosocial behavior. Whereas two subtypes of aggression(physical aggression and relational aggression) correlated negatively with sociometric popularity, perceived popularity correlated positively with relational aggression in 6th grade. (2)Social behaviors consistently emerged across developmental periods as predictors of popularity. (3)Academic ability was an important characteristic of popular children. (4)Teachers' praise and punishment affected popularity in kindergarten and $2^{nd}$grade children, but peer effect was more important for $4^{th}$ and $6^{th}$graders.

온라인게임은 출시 후 2~3개월 안에 인기를 얻지 못하면 시장에서 퇴출되는 게 일반적이다. 만성적인 자금 압박 등으로 인해 결국 서버를 내렸던 무협 온라인게임, ‘디오온라인’역시 그렇게 사라지는 듯 싶었다. 그런데 이변이 일어났다. 2년만에 서비스를 재개한 이 게임은 지난해 12월 동시접속자수 6,000명을 기록하더니 올해에는 최고 1만4,000명을 넘어서는 등‘후폭풍’이라는 표현이 어울릴 정도로 화려하게 재기했다. 뒤늦게 인기몰이에 성공한 디오온라인을 살펴봤다.

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.

With the recent revitalization of the shared economy, bike-sharing services are gaining huge popularity in the bicycle sector. Bike-sharing services are characterized by reducing environmental pollution and borrowing bicycles at low prices. This study investigated the mechanisms for the formation of customer's continuance intention toward bike-sharing services. The theoretical framework clarified the role of perceived value and trust in enhancing customer's continuance intention. Perceived usefulness, perceived ease of use and perceived enjoyment are considered as the vital factors of enhancing perceived value and trust in a service provider. The research model was validated by data from 217 bike-sharing users in China. Both perceived value and trust in a service provider had a significant impact on user's continuance intention. However, the analysis results showed that perceived usefulness does not have a significant impact on both perceived value and trust in a service provider. Perceived ease of use and perceived enjoyment played a significant role in enhancing both perceived value and trust in a service provider. Our results are expected to provide academic and practical implications for bike-sharing services.
