This study investigated prevalence rates and differences in social behaviors, psychosocial adjustments, and language ability of preschool children who engaged in bully/victim subgroups: aggressive victims, passive victims, bullies, and non-involved. The participants were 297 preschool children and their teachers in Jeju City. The teachers measured children's peer victimization, social behaviors, and teacher-child relationships. Children's language ability and self-concept were also assessed by individual interview. There were significant differences in social behaviors, psychosocial adjustments, and language ability among the bully/victim subgroups. Aggressive victims included in a high risk group characterized by a high level of aggression, ADHD, peer rejection as well as conflicted relationships with teachers. Moreover, they had limited language ability. The findings highlight behavioral heterogeneity among the bully/victim subgroups in early childhood.

The purpose of this study was to examine gender differences in the impact of exposure to peer delinquency among elementary school-age students and the mediating effects of aggression. The study utilized 458 cases (220 male students, 238 female students) of data from the 2015 Korea Welfare Panel Study (KoWePS) conducted by the Korea Institute for Health and Social Affairs (KIHASA). The theoretical frameworks used in this study included Bandura's social learning theory, Akers' social learning theory, and Sutherland's differential association theory. The findings were as follows. First, there was no statistically significant effect on peer group's delinquency experience overall, aggression, and delinquency experience by gender. Second, male students' delinquency experience of their peer group had a statistically significant effect on their delinquency, however, this was not true for female students. Third, in the case of male students, aggression was found to mediate the relationship between peer group delinquency experience and their own delinquency, but not for female students. From these findings, we suggest a practical and policy-driven intervention plan, focusing on reducing the contact frequency of delinquency experience and aggression, The purpose of this study was to examine gender differences in the impact of exposure to peer delinquency among elementary school-age students and the mediating effects of aggression.

This study was performed to assess the amount of altered serotonergic responsivity in individuals with repeated aggressive behaviors compared with normal controls. Sixteen aggressive(delinquent criminals with repeated aggressive behaviors) and seventeen controls(medical college students) were selected and assessed their severity of aggression by several psychological instruments. The platelet $^3H$-imipramine binding sites which is known to correlate the serotonergic function of the central nervous system were measured. The results are as follows. 1) Mean scores of physical aggression in the aggressive subjects were found to be significantly higher than normal controls(p<.01). And impulsivity, hostility, psychoticism in the aggressives were found higher than controls, also. 2) In the paltelet $^3H$-imipramine binding, the aggressives had a tendency of reduced maximal binding sites(Bmax) comparing with controls(p=.0841). 3) There was no statistically significant differences between two groups in the binding coefficients(Kd) of platelet $^3H$ Imipramine binding. 4) The value of maximal binding sites(Bmax) showed significant inverse correlations with aggressive scale scores of PFAV(r=-.6311), and physical aggression scale scores of CTS(r=-.5377).

This study examined conditions and influential factors of psycho-behavioral adjustment in abused children who had been returned home after out-of-home care. Subjects were selected nationwide from the Center for the Prevention of Child Abuse. Subjects were 54 cooperative children selected from among 126 returned children : they were older than 11 years of age and had experienced more than one day in out-of-home care between January 2002 and December 2003. Findings were: (1)children had such psychological adjustment symptoms as withdrawal, depression, or anxiety, rather than symptoms of misdeeds and aggression. (2) Level of self-esteem and re-abuse were the great influential factors in psycho-behavioral adjustment. This result shows that the processes of out-of-home care and returning home remain important issues for abused children.

The purpose of this study was to analyze the effects of both social-status and mode of stimulus-presentation on children's empathic behavior, where empathy is defined as either the comprehension and recognition of an affective state in stimulus persons (others) or the empathic response to that perception. Middle-and lower-class kindergarten children were presented with a series of either short-sentence stories or short-pictorial stories. The subjects were asked to indicate how the child in each situation felt by selecting a "happy", "sad", or "angry" face to complete the picture accompanying each story. Immediately following the first question, children were asked to state verbally how the child in the picture might feel. The main results were (1) The mean empathy scores for the comprehension and recognition of an affective state in others and the empathic response to that perception was higher in middle-class children than in lower-class children. (2) There were differences in empathy scores to the three affective situations, i.e. the mean score for both happiness and sadness was significantly greater than for aggression, and (3) The empathy scores in the pictorial-stories were greater than in the sentence-stories.

The purpose of this study was to raise validity of the result through using national data, to analyze the effect of children's smartphone addiction on aggression and moderating effect of parenting styles on the relationship between children's smartphone addiction and aggression. The data were obtained from 4th waves of KCYPS(Korean Children Youth Panel Study), and 1,686 4th graders in elementary schools who have smartphone were analysed. To achieve the purpose, this study executed frequency analysis, descriptive statistic, and hierarchical multiple regression analysis through SPSS 21.0. The results of this study are as follows: First, the higher children's smartphone addiction level, the higher children's aggression goes. Second, parents' supervision, affection, neglect have moderating effects on the relationship between children's smartphone addiction and aggression which means parenting styles could reduce children's aggression despite serious smartphone addiction. Based on these results, this study suggests that the combination of preventive discipline of smartphone addiction and parental education program is needed to reduce children's aggression which is main factor of bullying. In addition, this study suggests the establishment of special arrangement such as 'shut down' for smartphone addiction prevention.

This study examines the relationship between a mother's psychological well-being and children's problematic behavior(withdrawal, depression anxiety, aggression and emotional instability). In order to expand the study on the relationships, special attention was given to the possible mediator effects of mother's coping style with children's negative emotions. The subjects were 305 mothers with children 4-5 years old residing in the cities of Cheonan and Seongnam. It was found that mother's psychological well-being was significantly related to the level of children's withdrawal, depression anxiety, aggression and emotional instability. The mother's coping style with children's negative emotions were also significantly related to the mother's psychological well-being. In addition the mother's coping style with children's negative emotions was found to be a significant mediator of the relationship between mother's psychological well-being and children's. This was especially so for internal problems behavior as like withdrawal, depression anxiety and emotional instability that were perfectly mediated by the mother's coping style with children's negative emotions. Aggression, external problems behavior was partially mediated by the mother's coping style.

This study investigated the cross-cultural differences in temperament among Chinese, Korean-Chinese, and Korean children. Subjects were 1,046(258 Korean-Chinese, 290 Chinese, and 498 Korean) 4th graders from Yanji in China and Seoul and Ulsan in Korea. The short form of the Early Adolescent Temperament Questionnaire Scale-Revised containing 10 scales of 54 items was translated into Korean for Korean and Korean-Chinese children and into Chinese for Chinese children and was administered to children via home-room teachers. Chinese children rated themselves higher on activation control, attention, and pleasure- and perceptual-sensitivity subscales than other groups. On the contrary, Chinese-Korean children rated themselves higher on the affiliation subscale and Korean children rated themselves higher on the aggression subscale than other groups. There were larger gender differences among Chinese and Korean-Chinese than among Korean children: Gender difference was found in activation control, aggression, and attention subscales among Chinese children and in affiliation, aggression, attention and fear subscales among Korean-Chinese. There was only significant difference in pleasure sensitivity among Korean. Rapid westernization in Korea seems to be responsible for this result. Since there were significant differences of temperament between Korean and Korean-Chinese, and between Chinese and Korean-Chinese, it was interpreted that children's temperament is influenced by both their environment and genetic endowment.

This research examined the trajectories of peer rejection in preschool children. This study also investigated the gender differences in the intercept and slope of the trajectories for peer rejection along with the influences of aggression, withdrawal and language ability on the trajectories of peer rejection. A latent growth curve model investigated peer rejection in 3 to 5 year olds. Three hundred and thirteen 3-year-old children were recruited from five preschools and 14 daycare centers. The children's language ability was measured by a Wechsler Preschool and Primary Scale of intelligence verbal test and teachers completed measurements for aggression and withdrawal. A peer nomination inventory was used to assess peer rejection. Children were asked to nominate three classmates who they do not like to play with. The research findings showed that peer rejection decreased during the preschool years. Compared with girls, boys showed higher levels of peer rejection and a slower change rate of peer rejection. Girls who were aggressive showed high levels of peer rejection and a slow change rate of peer rejection. Moreover, girls who had a high levels language showed low levels of peer rejection and a slow change rate of peer rejection. These findings imply that language ability could be a protective factor of peer rejection for girls.
