학교폭력은 교육 환경에서 심각한 문제이다. 피해자에게 심리적 고통과 육체적 상해를 입히고 학교 내 안전과 안정성을 위협한다. 이에 많은 교육기관과 정부 기관이 학교폭력 예방과 대처를 위한 다양한 방안을 제시하고 있지만, 여전히 어려운 문제이다. 최근에는 인공지능 기술을 활용하여 학교폭력 방지와 대처에 관한 연구가 이루어지고 있다. 본 연구에서는 YOLOv5(You Only Look Once version 5) 딥러닝 알고리즘을 활용하여 학교 내부에서 발생하는 폭력 행위를 실시간으로 탐지하는 모델을 제안한다. 이 모델은 CCTV와 같은 영상 데이터를 입력으로 받아들여 학교 내부에서 발생하는 폭력 행위를 실시간으로 식별하는 것을 목표로 한다.

This study investigated the effects of individual characteristics, school factors, and community factors on adolescent school violence behaviors. Data from a total of 1,777 middle school students from 50 schools in the Seoul and Gyeonggi regions were used for analysis. A hierarchical generalized linear modeling was employed to conduct a two-level analysis. Results showed that adolescents' individual factors, including attitudes toward violence, parental attachment, child abuse experiences, and affiliation with delinquent peers, as well as school factors including teacher's abusive classroom discipline, affected adolescent school violence behaviors. In addition, neighborhood disorder was found to be significantly positively correlated with adolescents' school violence. The results of this study suggest that for an understanding of school violence and to prepare countermeasures accordingly, integrated consideration of various environmental contexts in adolescents' daily lives, such as family, school, and community environments, is necessary. A multidimensional, integrated intervention plan to effectively resolve school violence based on these research results is discussed.

School Violence is one of the most serious problems faced by Korean. As this serious problem becomes social issue in nation, many researchers have tried to find out the most effective solution of that problem and the reasons for why prevention of school violence are failed in such mind-hurting activities. The government and NGO proposed many the alternative to prevent the school violence. But the effectiveness of the alternatives art questionable. Last year Busan Metropolitan Police Agency and Busan Education Administration proposed new alternative in united cooperation which is namely Administration proposed new alternative in united cooperation which is namely 'school police' for school violence. School Police is composed of the retired teachers and ex-police officer, to do a prevention activity of school violence, which is expected to effectively curtail school violence in the assigned school. It is first networking try to prevent of school violence as a team of police and teachers in Korea. But the type of Korean school police system is different from American's school police, like as LASPD which is of sworn police officers. Korean school police is to employ a kind of school liaison officers. Though 'School Police System' got good reaction from students and citizen in Busan, It has some defects to be solved in future. So it hard to note that their efforts have been successful in curtailing the prevalence of school violence. In this paper, I present the new type of new 'Social Security Network Model' for school violence by repairing of 'korean school police system'. The problem of the school violence is not the problem of the school but the problem of society. In such viewpoints, It is important to plan a security network model which is participate in police officers, teachers, community and government. To prevent school violence effectively, I propose this new social security network model which based on theory of Community Oriented Policing, aggressive policing and CPTED technique.

School violence that have occurred recently, showing a tendency to collectivization and diverse types of violence, as well as the quality and increase the damage levels. School violence in the home, school, and social factors, but is caused by the lack of awareness about the violence and the reporting of consciousness due to poor acts of violence indirectly assisted. The only place violence has caused the school to establish the legal and institutional arrangements in order to minimize school violence have no choice but to limit its effectiveness is negligible. The problem of school violence in connection with the problem of juvenile crime prevention and control, and punishment should be made of the complex and layered. Operation and School police system, School safety keeper system, school sheriff system since 2005, each municipality in order to minimize school violence, but have no practical help to limit the visible and symbolic effects. Nonexistent professional staff of the institution or school safety monitors emphasis on monitoring the physical state of the system in the form of 'guards' departure inherently have limitations. Also, to prevent criminal acts or violence in the state is not given special privileges and the appropriate role for the school keeper is a problem with the system. Report no other role can not be expected. Should therefore be preceded by a systematic improvement and training of experts in order to prevent school violence, and home and school, in terms of social support and measures.

The comprehensive countermeasures against school violence recently announced by the government include some content on physical education classes. Physical education has long been ignored in school paradoxically in spite of the deteriorating physical strength and health of adolescents. The physical education subject undervalued in the middle of overly excessive competitions for college entrance exams finds its core goal in whole person education and officially emphasizes the development of personality aspects, which means that physical education claims important significance by providing diverse approaches to school violence prevention. This study thus set out to enhance the roles of physical education for school violence prevention. In Korean society, school violence has taken deep root due to the combined results of individual, family, school and community factors, the growth-first policy driven by compressed modern growth, and neoliberalism based on economic efficiency. School violence possesses such fixed value systems and convictions in Korean society. Education has failed to achieve some effectiveness because of the serious level of school violence, which calls for assessment of ideology having big impacts on educational environments. Given that it has been rediscovered that physical education has legitimacy of alleviating or preventing school violence through its value, an alternative to eradicate school violence should start with physical education normalization in school. Specific alternatives including the activation of sports clubs in school will be established as more fundamental practical alternatives when accompanied by the development of school violence-related programs and the operation of in-service training programs for physical education teachers.

To validate the effects of students' individual factor, school organizational factor, and teacher factor on violent behavior toward peers in school, this study applied Hierarchical Linear Modeling and analyzed it using the HLM 7 program. To this end, it used survey data of students from 50 middle schools in Seoul and Gyeonggi province. A total of 1,777 cases from 50 middle schools were used for individual student-level analysis (Level 1), and used for school-level analysis (Level-2). According to the results of the analysis, student-level variables such as attitude toward violence, experience of child abuse at home, and delinquent peers had significant effects on school violence. The effects of violent discipline by teacher, which are used as a school-level variable, was statistically significant. Based on the result of the study, action plans and policies to resolve school violence were discussed.

This study looked at how children's mental health is affected by Domestic violence and school violence at home and school after Covid-19, as well as how these victim experiences relate to children's mental health. This study surveyed 650 students from 14 middle schools in Wanju, Korea. The moderating effect of smartphone overdependence in the experience of violence and mental health was investigated. Major research findings: First, children's exposure to domestic violence and school violence has a significant impact on smartphone dependence. Second, children's exposure to domestic and school violence has a significant impact on their mental health. Third, it has been demonstrated that smartphone dependence is statistically significant in the relationship between domestic and school violence. Based on these findings, we present a convergent intervention and practice strategy for children in the Covid-19 era to cope with mental health problems and expand the support system.

This study aims to examine the effects of teachers' critical consciousness on their attribution of cause and responsibility about multicultural students' school violence victimization and their prediction on students' school adjustment. To this end, we presented four scenarios depicting multicultural students' school violence victimization and measured teachers' critical consciousness, cause and responsibility attribution, and school adjustment prediction. Results showed that teachers endorsing higher levels of Egalitarianism tended to attribute causes and responsibility to situational factors, rather than to a multicultural adolescent being victimized by school violence. The levels of Perceived Inequality of critical consciousness did not have significant effects on these variables. Also, teachers with a higher level of Egalitarianism tended to predict multicultural adolescents' school adjustment more negatively. Based on the current findings, we discussed implications on teacher education for promoting teachers' multicultural competence, along with limitations and directions for future research.

School violence is now considered not only as a problem for a victim and a offender themselves, but also as a social problem that requires responsibilities of school, home, society, and even nation. Crimes and risk factors are various inside and outside of school. In terms of solving those problems, this study examines the actual condition of school violence among students. In addition, it is considered what efforts are conducted by police to establish a safe school environment and the problems that derive from it. Futhermore, this study aims to discuss the ways of using the private security with regard to dealing with school violence. In this society, the expectation of security service from the police is increased as time passed. However, police has limited resources, thus it is beyond their practice. Policing has changed from being monopolized by government to cooperating with various security agents. Community is not considered as the subject for enforcing the law anymore, but as the cooperator for effective policing. With regard to the limitation of police force, using the private security is an effective alternative. Therefore, it is required that private security should be assigned legal authority and shared information with schools in order to patrol the blind spot. Finally, school violence prevention efforts should be conducted by applying physical and electronic security.
