This study focuses on adolescent prosocial behavior as one of the necessary elements for youth to grow as a healthy member of the society. The purpose of this study is to examine the effects of peer group on adolescent prosocial behavior by comparing the peer influence model and the individual characteristics model. For the study, we conducted hierarchical multiple regression analyses using the data from the Korean Youth General Survey 2008, administered by the Ministry of Health and Welfare. Results show that friends' prosocial behavior had a positive impact, but friends' antisocial behavior had a negative impact on adolescent prosocial behavior. When individual characteristics including self-esteem and empathy were analyzed simultaneously, empathy, self-esteem, friends' prosocial behavior, and friends' antisocial behavior were found to be statistically significant. The strength of association between individual characteristics and adolescent prosocial behavior was greater than that of friends' behaviors. Also, significant moderating effects of individual characteristics on the relationships between adolescent prosocial behavior and friends' behaviors were found. For example, the positive effect of friends' prosocial behavior on adolescent prosocial behavior increased as adolescent's level of self-esteem increased. On the other hand, the negative effect of friends' antisocial behavior on adolescent prosocial behavior decreased as adolescent's level of empathy increased. Based on the findings, both the peer influence model and the individual characteristics model were considered valid in explaining prosocial behavior of Korean adolescents. Finally, implications of this study for positive youth development were discussed.

The purpose of this study was to explore the impact of scientific inquiry-based peer teaching experience on pre-service elementary teachers' science teaching efficacy, anxiety to science and attitude toward science. The participants of this study included 118 pre-service teachers. The pre-post paired t-test design was implemented to examine the effect of this program. In addition, the semi-structured interviews were carried out for investigating their changes of affective characteristics. The result of this study showed that inquiry-based peer teaching provided pre-service teachers with the opportunities to enhance their science teaching efficacy and attitude toward science and reduce their anxiety to science. The findings imply that it is possible to meaningfully change elementary teachers' affective characteristics when effective strategies are adequately adopted.

The purpose of the present study was to explore the stability and changes of participant roles in the bullying process, namely, bullies, victims, followers, outsiders, and defenders. In addition, this study examined associated environmental characteristics of both followers and defenders in sixth graders among peer bystanders in the fifth grade. The participants consisted of 461 children from grades 5 to 6(male: 239, female: 222). Data were collected at one year intervals for two data points. The results indicated a moderate consistency in the participant roles the children take across time. Followers and outsiders tended to change differently in their roles one year later. On the other hand, defenders, bullies, and victims tended to keep the same role. The defenders group generally had higher levels of peer attachment, teacher attachment and community's supervision than the followers group. The implications for future research and intervention in bullying were also discussed.

The purpose of this study was to examine the pathway in which children characteristics, maternal warmth, and children's academic competence affect the quality of children's peer relationships. A total of 291 children (Mage=11.4) responded to questionnaires DOTS-R (Windle & Lerner, 1986), MBRI (Schaefer, 1959), Academic Self-Efficacy Scale (Kim & Park, 2002), and FQQ (Parker & Asher, 1993). Data were analyzed via Structural Equation Modeling. Our results indicated that children's academic competence fully mediated the association between temperament and the quality of peer relationships, whereas it was a partial mediator in relations between maternal warmth and the quality of peer relationships. A difference in terms of gender was also present in this path model. In conclusion, children's temperaments and maternal warmth affected the quality of peer relationships both directly and indirectly through children's academic competence.

The present study investigated the influence of withdrawal on children's best friendship including prevalence of best friendship, friendship quality, and friends' psychosocial characteristics. Subjects were 471 fifth and sixth graders recruited from two public schools. The peer nomination index was used to assess peer victimization, withdrawal, and prosocial behavior. Peer rejection and acceptance were also measured. Children reported on the quality of their friendships using the Friendship Quality Scale(Bukowsi et al., 1994). Results showed that compared to control group, withdrawn children had fewer best friends and perceived their friendship quality more negatively. Moreover, withdrawn children are similar with their best friends in respect with prosocial behavior, withdrawal, peer victimization, and peer rejection level.

Objective: Delinquent peers are important predictors of adolescent delinquent behavior. Few studies have classified individuals into groups based on patterns of delinquent behavior among youth and their peers. This study identified latent groups based on adolescent-peer delinquency and examined psychosocial characteristics of each latent group. Methods: First, the study employed latent class analysis based on a nationally representative data of South Korean middle school students (N = 2,277). Both adolescent and peer delinquent behaviors comprised 13 items in the questionnaire that was self-reported by adolescents. Second, the study used multivariate regression models to analyze psychosocial symptoms of latent groups and conducted Wald tests to compare differences among latent groups. Results: Patterns of adolescent-peer delinquency were classified into six latent groups. "Mutual total delinquent group (1.2%)" showed high rates in most delinquent experiences. "Mutual status delinquent group (5.7%)" mainly experienced status delinquency, "Mutual violence delinquent group (5.3%)" showed high rates of violent delinquency. "Peer-only total high delinquent group (3.8%)" reported friends to have engaged in all types of delinquency and "Peer-only total medium delinquent group (11.8%)" reported peer involvement in multiple status and few violent delinquency. Finally, "low risk group (72.2%)" reported low rates of delinquency for themselves and their friends. Regression analysis showed that every "mutual" delinquent group presented significantly worse psychosocial problems than the "low risk group." Conclusion: Using person centered latent class analysis, this study classified six latent classes while considering both delinquent agents and various types of delinquency and investigated specific groups with greater risk of psychosocial problems.

This study investigated children's friendship factors such as number of friends, friendship quality, and friends' characteristics as a function of children's sociometric status. The concordance between children's and their friends'perceptions of friendship quality was examined. Subjects were fifth grade students recruited from two public schools. The peer nomination index assessed peer rejection and acceptance. Positive and negative nominations as well as social preference identified children into rejected and popular groups. Children who nominated each other on their list of friends were considered mutual friends. Children reported the quality of their friendships using the friendship quality scale. The results showed that rejected children had fewer mutual friends compared to popular children. Rejected children as well as their friends perceived their friendships less positively. Moreover, rejected children's perception showed lower correlations with their friends'perceptions than popular children's perceptions. Furthermore, rejected children were similar with friends in respect to peer rejection level. It was concluded that rejected children's problems in their peer group and dyadic friendships may mutually influence each other. The findings from this study highlight the need for future research on friendship quality and psychosocial adjustment for rejected children.

The current study examined the effects of socio-demographic characteristics and peer relations on the emotional, behavioral, and comorbid disorder symptoms among low-low-SES children, using the Young Lives Survey: an International Study of Childhood Poverty: Round 1, 2002. Participants were 1,000 8-year-old children (502 boys and 498 girls) from low-low-SES families. Data were analyzed using ANOVA, t-tests, post hoc test (Scheffe's method), correlations, and multiple logistic regression analyses according to the analysis strategy. There was a moderate correlation between selected socio-demographic variables and emotional/behavioral disorder symptoms, and the caregiver's marital status, child's health compared to others, child's work status corresponded to significant differences in their emotional/behavior levels. Regarding the logistic regression analysis, in addition to the effects of socio-demographic variables reflecting the characteristics of less-developed countries, marital status, child's working status, and conflicts with peers proved to be detrimental to emotional, behavioral, or comorbid disorder symptoms in low-SES children, who have been lack quality parenting, social resources, and child human rights. Results indicated the need to develop health care services that would address those problems and appropriate intervention and prevention programs targeting children in low-income families. Moreover, careful assessment and intervention for child's health status, child's working status and peer relationship problems are suggested as possible strategies for helping children at risk of exhibiting further problematic behaviors.

The peer review learning is a method which improves learning outcome of students through feedback between students and the observation and analysis of other students. One of the important problems in a peer review system is to find proper evaluators to each learner considering characteristics of students for improving learning outcomes. Some of peer review systems randomly assign peer review evaluators to learners, or chose evaluators based on limited strategies. However, these systems have a problem that they do not consider various characteristics of learners and evaluators who participate in peer reviews. In this paper, we propose a novel prediction approach of learning outcomes to apply peer review systems considering various characteristics of learners and evaluators. The proposed approach extracts representative attributes from the profiles of students and predicts learning outcomes using various regression models. In order to verify how much outliers affect on the prediction of learning outcomes, we also apply several outlier removal methods to the regression models and compare the predictive performance of learning outcomes. The experiment result says that the SVR model which does not removes outliers shows an error rate of 0.47% on average and has the best predictive performance.
