The purpose of this study is to explore the mediating effect of violence justification, including actor-effect and partner-effect, in the process where the offense motive affects dating violence. The subjects of this study were 135 unmarried male and female couples aged 19 and over who were dating for more than 3 months, and each couple was subjected to a self-report scale on motives, justification of violence, and dating violence. Based on these paraphrasing, as a result of analyzing the path model using the Actor-Partner Interdependence Model, Men and women's motivations showed a direct effect on their dating violence, while women's motivations showed a significant partner effect on men's violence. The male's motivation also had a significant impact on his dating violence and partner's abuse of dating violence as a mediator for justification of his violence. On the other hand, the mediating effect of justifying violence in women was not significant. These results show that there is a gender difference between the motives for violence and the paths for justifying violence in the sex violence of men and women. Finally, the implications and limitations of this study, and suggestions for follow-up studies were discussed.

This study was conducted to identify the relationship between child abuse and school violence and whether aggression and depression have any mediating effects on this relationship. This study analyzed the responses of 1,937 eighth grade students. The main results of this study were as follows. First, child abuse was positively correlated with school violence aggression and school violence victimization. Second, aggression and depression mediated the effect of child abuse on aggression and victimization, respectively. Third, aggression mediated the effect of child abuse on victimization. Fourth, although there was a reciprocal causal relationship between aggression and victimization, school violence victims who were abused by their parents were less likely to be the perpetrators of violence themselves. These findings have implications regarding the use of counseling intervention to prevent violence in schools.

The purpose of this study was to identify the persistent and dynamic association between bullying and victimization. Gender differences in patterns of school bullying was hypothesized based on the literature. Analysis were based on waves 3-6 of the Korea Children and Youth Panel Survey, a nationally representative data of primary and secondary school students in South Korea (N = 1,881). Autoregressive cross-lagged model was employed to identify the reciprocal association between bullying and victimization in longitudinal data. As hypothesized, regardless of gender, lagged effects were statistically significant between each time points such that current bullying caused future bullying and current victimization led to future victimization. However, there was no cross-lagged effects of current victimization on future bullying nor current perpetration on future victimization for both male and female youth. Findings from this study may have implications for designing policies against school bulling. Not only is short-term intervention for handling immediate psycho-social maladjustment important, but so are long-term plans that prevent youth from falling into continued perpetration and victimization in the system of school bullying.

This study was designed to test whether middle school students have moderating effect of empathy ability on group bullying behavior. The subjects were 488 middle school students in Busan area, The mean difference test and regression analysis were performed using the SPSS 20 program and the related variables were standardized to show the characteristics of the control effect. The results of this study are as follows: First, as the experiences of the perpetrator and the experience of the autonomous group, the group bullying behaviors were higher, and it was confirmed that the perpetrators were important variables for predicting the bullying behaviors. As a predictor of bullying behavior, it was identified as an important variable. Second, empathy ability has a moderating effect of alleviating the relationship between perpetrator's harmony and bullying behavior, and the relationship between onlooker and bullying behavior. Third, according to gender analysis, male students were more exposed to bullying behaviors than female students. Through these discussions, practical suggestions for social welfare, academic suggestions, and suggestions for follow-up studies were made.

Feeding plants of rice water weevil(RWW) adult and larvae were observed. Thirteen families including 104 species were found as host plants of RWW adult, and 74 species of them were newly identified as its host. Thmedia triandra var. japonica, Luzula capitata, Agropyron tsukushiense var. ransiens, and Zoysiama crostachya were most favorable hosts of adult RWW. Host plants for larvae were 9 species of weeds including Cperus nipponicus, Eleccharis kuroguwa, Sagittaria trifolia, and Claviceps purpurea in the rice paddy fields.

This paper has for its object to propose AFOD(Adaptive First-Order Decimator) which sets a value of decimated element as an average of a value of neighbor intelligible component and a output value of FOD(First-Order Decimator) for the target pixel, and to analyze its performance in terms of subjective image quality and hardware complexity. In the proposed AFOD, a target pixel located at the center of sliding window is selected first, then the gradient amplitudes of its right neighbor pixel and its lower neighbor pixel are calculated using first order derivative operator respectively. Secondly, each gradient amplitude is divided by the summation result of two gradient amplitudes to generate each local intelligible weight. Next, a value of neighbor intelligible component is defined by adding a value of the right neighbor pixel times its local intelligible weight to a value of the lower neighbor pixel times its intelligible weight. Since the proposed method adaptively reflects neighbor intelligible informations of neighbor pixels on the decimated element according to each local intelligible weight, it can effectively suppress the blurring effect being the demerit of FOD. It also possesses the advantages that it can keep the merits of FOD with the good results on average but also lower computational cost.

The main objectives of this study are to examine the effects of stress on the experience of doing harm of the children and adolescents and to examine the moderating effect of human rights consciousness on the relationship between the stress and the experience of doing harm. To do this, we analyzed the data obtained from Survey on Human Rights of Children and Adolescents in 2015. The subject is 10,424 from the 4th grade of elementary school to the 3th grade of high school. To investigate the moderating effects of variable, we have conducted a hierarchical regression analysis and confirmed changes in explanatory power. As a result of that, first, it suggests that stress and human rights consciousness have direct effects on the experience of doing harm. This results show that the lower stress and the higher human rights consciousness is, the lower experience of doing harm is. Second, it was found that human rights consciousness is moderating variable on the relationship of between the stress and the experience of doing harm. Based on this results, this study has proposed the implications and limitations of it and suggestions for further study.

This study focused on the problem behavior after drinking, and examined the effects of temperament of adult drinker on offensive behavior and analyzed the sequential mediating effects of aggression and drinking behavior. To this purpose, 299 subjects were assessed through the Temperament and Character Inventory(TCI)-for adults, Korean Aggression Questionnaire, and Korean Alcohol Use Disorder diagnosis. As the results, 'Novelty seeking' had the highest level of explanation for aggression. In the relationship between 'Novelty seeking' and offensive behavior, mediating effect of aggression and drinking behavior were significant. In its course, sequential mediating effect of both was shown as complete mediation. This result implies that the aggression and drinking behavior were the factors of connecting 'Novelty seeking' and offensive behavior, and the characteristic of 'Novelty seeking' does not have direct influence on offensive behavior but only through aggression and offensive behavior that it has such effect.

The purpose of this study was to examine the mediating effect of functional and dysfunctional expressions of anger on the relationship between covert narcissism and dating violence among college students. The study also investigated gender differences with regard to covert narcissism, dating violence, and functional and dysfunctional expressions of anger. To this end, 339 college students (133 males, 206 females) with heterosexual dating experiences in the Busan Metropolitan area were recruited. They responded to the Covert Narcissism Scale, the Revised Conflict Tactics Scale 2, and the Korean adaptation of the State-Trait Anger Expression Inventory. The results were as follows. First, covert narcissism, dating violence, and functional and dysfunctional expressions of anger differed significantly by gender. Second, there were statistically significant correlations between covert narcissism, dating violence, and functional and dysfunctional expressions of anger. Third, multiple regression analysis showed that dysfunctional expressions of anger for males were positively correlated with dating violence while functional expressions of anger were negatively correlated. For females, dysfunctional expressions of anger were positively correlated with dating violence while functional expressions of anger were not significantly correlated. Fourth, dysfunctional expressions of anger completely mediated the relationship between covert narcissism and dating violence for both males and females, but functional expressions of anger had no mediating effect. These results suggest that dysfunctional anger expression control program should be developed for students which may help those with covert narcissistic tendencies to functionally express their anger. Future research should analyze dating violence prevention and counseling programs.
