Objective: The present study examined the effects of school violence victimization and self-control on cyberbullying perpetration in middle school students and investigated whether self-control moderated the relationship between school violence victimization and cyberbullying perpetration. Methods: The participants of this study were 315 middle school students (172 boys; 143 girls) from three middle schools in Seoul and Incheon. To measure the level of cyberbullying perpetration, the Bullying/Victimization Questionnaire was used. School violence victimization and self-control were measured via the School Violence Victimization Scale and the Self-Control Scale, respectively. The data were analyzed by means of descriptive statistics and hierarchical regressions. Results and Conclusion: The results indicated that school bullying victimization level increased cyberbullying perpetration level whereas self-control level decreased cyberbullying perpetration. In addition, self-control moderated the effect of school violence victimization on cyberbullying perpetration. That is, the influence of school bullying victimization on cyberbullying perpetration was greater when self-control was low, compared to when it was high.

This research tested the path model which examined the direct and indirect effects of family violence experience on perpetration of dating violence among college students. Two family violence variables such as witnessing parents' marital violence and being abused by parent were the exogeneous variables in the path model, while the mediated variables were consisted of (1) the social-learning-theory-derived variables such as acceptance of violence, positive outcome expectations of using violence, and aggressive conflict-coping behavior, and (2) control-theory-derived variables such as attachment, belief, and commitment. Data were from self-administered questionnaires completed by 332 male and 469 female students selected by stratified quota sampling method. The path analysis was done for males and females separately, since females reported significantly higher degree of dating violence than males. Results of the path analysis showed that first, for both males and females, being abused by parents directly and indirectly influenced dating violence, while witnessing parents' marital violence did not have effect on dating violence either directly or indirectly. Second, for male students, acceptance of violence and conflict coping behavior found to be the mediated variables in the effect of being abused by parents on dating violence. Third, for females, a control-theory-derived variable of belief as well as all three social learning theory-derived variables mediated the influence of being abused by parents on dating violence.

This study aimed to investigate how teacher's attitude toward violence affect students who experienced bullying victim in their role in making peer-to-peer violence deepen, and how students who experienced the bullying victim react to show aggression, and the aggression is blocked by teacher's attitude toward violence, resulting in decrease of doing the bystander's negative behavior. By conducing this study, this study ultimately aimed to ensure that the teacher's attitude toward violence is very important in preventing peer bullying in the classroom. To achieve this aims, this study conducted a survey of 820 fourth, fifth and sixth graders in 40 classes at 10 elementary schools and limited only 365 of the respondents who reported experiencing peer bullying victim. This study utilized the structural equation modeling method to analyze the data. The results were as follows. First, it showed that the lower the bystander's negative behavior in victims who experienced peer bullying, and the lower the responsive aggression reacted from the peer bullying, when the teacher shows an unacceptable attitude toward violence. Teacher's attitude toward violence also appears to affect peer bystander's negative behavior by mediating peer bullying victim's reactive aggression, indicating that the teacher's attitude toward classroom violence may reduce the aggression of students from the experience of victimization, and consequently prevent the classroom from becoming more leprosy by reducing peer bullying.

As shown in many precedent studies of sex violation, many rapes are done by acquaintances rather than strangers. Among them specially many are the cases carried out by date partners and so it is necessary to study on the date rape systematically and academically which is the most common sex violation. A recent study on the date rape executed in the country shows the seriousness of the problem clearly. The survey reported that 20.5 percentages of women had experienced the harmfulness of date rape. However compared with the general injured women, the injured ones of date rape rarely report it to related organs. The reason is that in the case of date rape both the injured ones and offenders just think of the injured things or offending works as a little excessive sexual relation or sexual contact, but not recognize it as sex violation. Therefore this study will introduce the results of precedent studies on the date rape based on the contents of Michael Shively, Perceived Risks of Date Rape, Judith M. Sgarzi, Victimology, and also introduce the prevention of the injury its countermeasures.

This study investigated subtypes of men who batter, and explored the differences among them. It was based on 217 subjects from all around the nation who received legal punishment. In the analysis of the typology, we specifically tested whether the Holtzworth-Munroe and Stuart proposed typology was verified. The results of the cluster analysis revealed support for their theoretical distinction for three types of abusers. These results imply that Holtzworth-Munroe and Stuart's batterer typology is applicable to Korean batterers to some degree. Type 1 men demonstrated the lowest levels of physical and psychological abuse toward their wives and were the least likely to have had a history of child abuse or alcohol problems. These men had lower MCMI scores and did not show any extraordinary personality traits. Men in this category were violent only against their wives, had relatively liberal sex role attitudes and had the most satisfaction in their intimate relationships. Type 2 men were violent only at home, using a moderate level of violence. These men had very high levels of dependency on others and showed a borderline, avoident or passive-aggressive personality. The amount of alcohol consumption was similar to Type 1, but scores of jealousy, self-esteem, and attitudinal variables were similar to Type 3 men. They lacked assertiveness skills and reported the least marital satisfaction. Type 3 men used the most severe violence and were violent both inside and outside the home. These men showed signs of antisocial and aggressive personality. They had experienced frequent physical abuse during childhood, were the most likely to abuse alcohol and had lower self-control. Type 3 were the most traditional in their views of women's roles and had attitudes supporting violence. Based upon the study findings, practical implications of enhancing treatment efficacy were considered.

The psychological problems following the experiences of school-violence could be more important than the physical problems. Victims could suffer from fear, depression, anger, lowered self-esteem, suicidal thought, and personality changes. To study the risk factors for school violence and the psychiatric problems after the experiences to school-violence provide us important informations to prevent and solve the problems of school violence. We examined clinical characteristics and psychosocial backgrounds of 13 adolescents who visited the psychiatric clinic after exposures to school violence from September, 1996 to May, 1997. The clinical data included intensity, motivations, durations, and methods of violence, psychiatric symptoms following exposure, findings of psychological test, and treatment course. The socioeconomic data included developmental characteristics of subjects, family characteristics, school life, and peer relationships. Of the 13 adolescents who experienced exposure to violence, 8 have experienced chronic psychiatric disturbances, 5 experienced transient psychiatric symptoms such as anxiety, depression, suicidal attempt who eventually returned to home and school life. Of the 8 adolescents who experienced chronic psychiatric disturbances, 4 experienced PTSD and depression lasting 3-6 months more, otherwise 4 showed converted features, such as aggressive behavioral disorder or perpetrator by strong compensatory effects after psychological shock. The subjects who have experienced chronic psychiatric disturbance have clinical characteristics such as physical or emotional abuse, physical illness or handicap, defects of ego functionings, and lack of family support. In summary, victims by school-violence manifested serious psychiatric disturbances, and they had clinically significant risk factors and some of them became perpetrators of school-violence.

Authors surveyed intrafamilial child sexual abuse in the children under 15years old in clinical. We sent the semi-structured child sexual abuse questionnaires to 7055 board certified pediatrics, obstetrics and gynecology, family medicine and emergency medicine. Total respondents were 1205. The results from these respondents were as follows. 1) The numbers of respondents who have had the experience of treating victims of intrafamilial child sexual abuses were 157(13.0% of total respondents). 2) Among the perpetrators, 58(36.9%) were siblings and 32(20.4%) 26(16.6%) were step-fathers, and respectively. The most common age bracket was 10s(39.5%), and the next was 40s and 50s (33.7%) Almost all(98.7%) of the perpetrators were male. 3) The mean age of victims was $12.1{\pm}3.3$ years old, and all of the victims were female, and the number of victims who had previous mental or physical handicaps and behavior problems were 5(3.2%) and 8(5.1%) respectively. 4) The ways by which intrafamilial child sexual abuses were found were abnormal behaviors 45(28.7%), victim's own report 40(25.5%), pregnancy 18(11.5%), pain complaint 13(8.3%), other person's report 13(8.3%), and detection during examination 12(7.6%). 5) Time lags between intrafamilial child sexual abuses and hospital visits were after 1 month 97(61.8%), from 1 day to 1 week 29(18.5%), within 1 day 21(13.4%), and from 1 week to 1 month 10(6.4%). 6) Physical complications were perineal wound 93(59.2%), hymen rupture 90(57.3%), pregnancy 68(43.3%), wound of other part of body 11(7.0%), and sexually transmitted disease 4(4.5%). 7) Treatment for victims were discharge 92(58.6%), admission, operation or transfer to a bigger hospital 25(15.9%), psychiatry consult 19(12.1%), report to police(10.9%) and social work consult 3(1.9%). These results suggest that considerable numbers of physicians have had the experience of treating victims of intrafamilial child sexual abuses, and intrafamilial child sexual abuses are the major medical as well as social issue in children in Korea.

This study was conducted to develop economic injury level (EIL) of onion thrips, Thrips tabaci, on welsh onion (Allium fistulosum L. var) in the early transplanting stage. The changes of welsh onion biomass, yield loss, and T. tabaci density were investigated according to the inoculation periods of T. tabaci. In the early transplanting stage of welsh onion, the yield loss (%) increased with increasing inoculation periods: 17.0, 53.3, 38.4, and 80.8% yield loss in 5, 10, 15, and 20 d inoculation periods, respectively. The relationship between Cumulative Insect Days (CID) of T. tabaci and yield loss (%) of welsh onion was well described by a nonlinear logistic equation. Using the estimated equation, EIL of T. tabaci on welsh onion was estimated to 30 CID per plant based on the yield loss 12% (an empirical gain threshold 5% + marketable rate 93% of welsh onion). ET was calculated to 24 CID, which corresponds to 80% of EIL. Until a more defined EIL-model is developed, the present results should be useful for T. tabaci management in early growth stage of welsh onion. The effect of T. tabaci attack on the yield of welsh onion in late growing season (120 days after transplanting) was also examined. The yield of welsh onion increased at a low population density of T. tabaci and decreased at higher densities, showing a typical over-compensatory response.

Objective: This study aims to thoroughly analyze the correlation effect size between domestic violence and school violence by meta-analyzing previous studies on the correlation between school and domestic violence. Methods: For this purpose, meta-analysis was performed on the selected research material, which consists of national research data collected from various databases from 2001 to April, 2019. 16 thesis and 9 papers on the correlation between school and domestic violence were selected. A random effect model analysis based on the homogeneity examination results was performed on the selected data. Results: The results showed, just as Cohen (1977) proposed, that the correlation effect size between domestic and school violence was 0.25, which is moderate. This is a somewhat lower number than the previous studies on the same subject presented. Of the sub-categories of domestic violence, physical violence and psychological violence appeared to have a correlation effect size of 0.34 and 0.28, respectively, with physical violence showing the highest correlation effect size. Of the types of domestic violence, witnessing spouse violence and experiencing neglect appeared to have a moderate correlation size effect of 0.24. All of these results were statistically significant. Conclusion/Implications: This study utilized meta-analysis as a comprehensive and systematic method to analyze the correlation effect between domestic and school violence. The results presented may lead to discussions on the subject's social implications, limits, and propositions for future studies.
