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 is to determine the variables affecting adolescents' conformity behavior in bullying. The study subjects were 753 middle school and high school students. The data were analyzed using Chi-Square, ANOVA, and hierarchical regression analysis. The major findings are as follows. 1. The variables affecting bully-conformity behavior were sympathy, close friends to confide in, anxiety, social skills, and family harmony. The variables affecting victim-conformity behavior were social skills, sex, attitude toward school atmosphere, anxiety, and sympathy. The variables affecting onlooker behavior were anxiety, sex, and close friends to confide in. 2. Sympathy, self-esteem and social skills were higher in the victim-conformity group than in the other two groups. Anxiety was higher in the onlooker group than in the other two groups. In the case of the victim-conformity group compared to the bully-conformity group, the parents showed more generous attitude toward their children, a more harmonious atmosphere existed within family members, and the group showed better relationship with teachers. Finally, the victim-conformity group showed a positive attitude toward school atmosphere, compared to the other two groups.

The purpose of this study was to examine the relationship of bully/victim experiences and bioethics of 5th and 6th graders. Participants were 326 elementary school students. Methods: The data was collected from 1th to 30th October, 2014 in G City. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and multiple regression and Scheff$\acute{e}$ post-hoc analysis by SPSS 18.0. Results: First, in regard to bioethics, significant factors were liking for growing plants (p<.001), emotions after killing insects (p<.001) and the number of friends (p=.003). In regard to bullying experiences, significant factors were gender (p=.021), religion (p=.026), participation in religious activity (p=.019), liking for growing plants (p=.009), insect killing experience (p=.009). The bioethics score of the victim group (2.70 point) were higher than the bully group (2.49 point). The relationship between bully/victim experiences and bioethics was negative. The factors affecting bioethics were liking for growing plants (${\beta}=.159$, p=.004), the number of friends (${\beta}=.124$, p=.030), experiences of being bullied (${\beta}=.352$, p<.001), emotions after killing insects (${\beta}=-.135$, p=.011). Conclusion: Therefore, based on the results of this study, it is required to develop rich learning content and a variety of teaching and learning models for bioethics. Efficient bioethics program would help elementary school students have a higher bioethics awareness. The entire society and families should wake up to the evil effects of school bullying and make concerted efforts to root it out with a sense of responsibility.

When observing the subjects and seriousness of Korea's Wang-ta, it is urgent that we know the characteristics of Wang-ta and its conditions. In this study, we investigated the definition of Wang-ta, which partly differs from bullying. Also, the phenomenal characteristics of collectivism, the victimization of an individual once stigmatized in the Wang-ta process, the generalization of the Wang-ta process where bullies extend their territory into general students were examined. Moreover, external environment such as Korea's school environment, negative house environment, and collective culture were examined. The three general structures in researching Korea's Wang-ta were presented. The first structure consists of a bully, victim, and a bully-victim. The second structure focuses on the certain groups, which consists of followers, outsider, and the defender. The last structure deals with the psychological characteristics of the participant roles, which are the bully, reinforcer, assistant, defender, victim, and outsider. Wang-ta prevention programs, which reflects the characteristics of Wang-ta, are presented. Implications on future Wang-ta prevention programs are discussed.

The purpose of this study is to reduce the group bully phenomenon of mildly mentally retarded(MR) students in middle schools. Video digital contents have been developed and applied to the class. As a result, the normal students' perception of MR students has improved drastically. Especially in the case of students who appeared in the film; their perception has changed a lot more than the students who didn't. Also, the students showed a tendency to recognize the scenes that were produced intentionally by the researcher In conclusion, it is effective to alter a student's attitude through the self-modeling video contents. Particularly, the self-modeling video contents that made by researcher's precise educational goal are more effective on the alteration of the students' perception and behaviors.

The purpose of this study was to analyze responses as bystanders of middle school girls in a simulated cyberbullying situation. This study also aimed to examine effects of bullying, victimization, anger-out, and state-anger on responses from girls as bystanders. The participants were composed of 2nd or 3rd grade middle school girls(N=59). Responses were classified into 7 categories(using explicit language, attacking, pass, changing topic, comforting victims, others, and conformity). Of these, attackings were classified according to the target(bully, victim, both, and ambiguous object). It was again classified as 'attacking response' and 'helping response' and was scored and summed according to the strength of the response and used as a dependent variable. Collected data were analyzed by correlation analysis and multiple regression analysis. The results of this study are as follows: First, the most frequent response was 'the others'(41.69%) followed by 'using explicit language'(20.34%), 'passing'(13.56%), 'attacking bully'(8.81%), 'conformity'(8.64%), 'changing topic'(6.61%), and 'comforting victim'(0.34%). Second, responses of attacking victim were positively influenced by the previous bullying experiences and acting anger-out, and were negatively influenced by the previous victimization experience. State-anger has a positively influenced on responses of the attacking bully and the helping victim. None of the variables were significant influenced on responses of the attacking both and ambiguous object. These results will be useful data to help middle school girls as bystanders properly intervene in cyberbullying situation. Finally, the limitations of this study were discussed along with suggestions for further research.
