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.

As the post-cold war era and globalization go on, national security problems which were not traditional national security problems such as terrorism, crime, environmental disasters, economic crises, cyber-terrorism, diseases, and energy problems threat humanity and nations and demands changes. Also, with the change, the concept of "big government" has emerged as the role of nation expanded. The modern society sees every country change from small government to big government in order to realize the establishment of welfare state. A comprehensive interpretation of security is needed in order to comprehensive protection of citizens beyond outside invasion such as crime, new disaster, terrorism. In Korea, incidents such as Cheonan-Ham, Yeonpeyong-Do, foot-and-mouth disease, Ddos terrorism, pirates hostages, mad cow disease, AI are happening and the humanitarian support for North Korea and the summit of South and North Korea are at a standstill. Also, National emergency management system, comprehensive emergency management center, countrol tower, national security system, cooperation with citizens, establishment of legal and institutional system are needed. The importance of this research is on the reestablishment of new national security and emergency management system according to the comparison between the national security and counter-terrorism system of Korea and that of the United States which is a leading country in this field. Also, the establishment of national emergency management act is needed as a statute for effective function as currently various laws and administrative organizations are dispersed.

With advancements in artificial intelligence technology, intelligent CCTV systems are being deployed across various environments, such as river bridges and construction sites. However, a conflict arises regarding the opening and closing of rooftop access points due to concerns over potential accidents and crime incidents and their role as emergency evacuation spaces. While the relevant law typically mandates the constant opening of designated rooftop access points, closures are often tacitly permitted in practice for security reasons, with a lack of appropriate legal measures. In this context, this study proposes a detection system utilizing intelligent CCTV to respond to emergencies that may occur on rooftops. We develop a system based on the YOLOv5 object detection model to detect assault and suicide attempts by jumping, introducing a new metric to assess them. Experimental results demonstrate that the proposed system rapidly detects assault and suicide attempts with high accuracy. Additionally, through a legal analysis of rooftop access point management, deficiencies in the legal framework regarding rooftop access and CCTV installation are identified, and improvement measures are proposed. With technological and legal improvements, we believe that crime and accident incidents in rooftop environments will decrease.

Recently, video surveillance is becoming more and more common as many camera are installed due to crime, terrorism, traffic and security. And systems that control cameras are becoming increasingly general. Video input from the installed camera is monitored by the multiscreen at the central control center, it is essential to simultaneously monitor multiscreen in real-time to quickly respond to situations or dangers. However, monitoring of multiscreen in a mobile environment such as a smart phone is not applied to hardware specifications or network bandwidth problems. For resolving these problems, in this paper, we propose a system that can monitor multiscreen in real-time in mobile-phone environment. We reconstruct the desired multiscreen through transcoding, it is possible to monitor continuously video streaming of multiple cameras, and to have the advantage of being mobile in mobile-phone environment.

The purpose of this study is to analyse motor vehicle communication network hacking attacks and to provide its prevention. First, the definition of motor vehicle communication network was provided and types of in-vehicle communication network were discussed. Also, bluetooth hacking attack cases were analysed in order to illustrate dangers of hacking attacks. Based on the analysis, two preventive measures were provided. First, Motor Vehicle Safety Standard Law should be revised. Although the law provides the definition of electronic control system and its standards as well as manufacturing and maintenance for safe driving standards, the law does not have standards for electronic control system hacking prevention and defensive security programs or firmware. Second, to protect motor vehicle communication network, it is necessary to create new laws for motor vehicle communication network protection.

The existing CCTV has limitation such as problem on usage of the off-line type of recorded image for specific investigation, and requirement on interactive operator intervention for real-time surveillance. Therefore, it is required to develop the intelligent CCTV equipped with various functionalities in order to overcome drawbacks mentioned above. In this paper, implementation methods of image-based virtual fence were proposed by using the spline curves with supplied control for setup of surveillance area. In addition, pre-alarm region within the predefined distance was established with tangent and normal lines extracted from control points. The image-based virtual fence can be used for remote detection of intrusion and provision of real-time intrusion alarm, and can be expected to use in safety-related application areas including security and crime prevention.

The idea of this study was derived from awareness of local governments and police's limitation on attempts to 'creating safe park'. The purpose of this study is to examine current political measures of preventing various types of possible crimes in the park and the limitation of those policies. Furthermore, this study aims to suggest possible explanations to utilize Private Security Sector for the effective and continuous way of managing park safety by considering legal and practical solutions and its expectations. The methods of analysis used in this study are, first, literature review of current park safety management policies. Second, this article examined implications of strategies of those policies throughout the case study of the USA's park safety policy. Third, this study suggested plans of action and role of Private Security Sector to improve park safety. The results present several arguments for the park safety. First, legislation of mandatory crime preventing programme in the early stages of designing park is required. Introducing the 'park special judicial police system' to the major parks for a immediate response to the crime can be one of suggestions. Moreover, proactive police response systems, such as one of the Seoul Metropolitan Police's policies- 'returning safe parks to a citizen' are required. Second, the case study of the USA regarding park safety confirmed that major parks in the USA have rigorous and detailed park regulations. It also showed that those parks take not only preventing measures, but also follow-up measures against crimes. Third, the results suggest creating human resources by contracting out Park Managers and Private Security Sector that have specialized experiences and techniques to prevent crimes and public disorders. Overall in this study, increased citizen's satisfaction level, control of continuous and systematic crimes, the spread of joint-production of public safety, and increased fields of the Private Security Sector are expected from the findings.

The Moon Jae-in administration insisted on reforming the prosecution for the reform of power institutions, and also tried to control the power of the prosecution through the establishment of a high-ranking public officials criminal investigation office. Then, what is the direction of the legal prosecution reform? Above all, it is a logic to drastically reduce the power of the prosecution. How to shrink it? First, it is necessary to control or check the power of prosecution and investigation that the prosecution has. Second, the key to the reform of the prosecution is perhaps to separate personnel rights from power. In order to exclude external pressure from the prosecution's personnel rights, there must be no instruction or intervention from the attorney general. To do this, the prosecutor general must go through various personnel evaluations, such as multi-faceted evaluation. Third, the essence of the High-ranking Officials Criminal Investigations Act is to deal with crimes of prosecutors, judges, police, and members of the National Assembly. It is also the core of the institutional mechanism to cover the corruption of one's family members while holding all the right to investigate, prosecution, and warrant claims, and to check the omnipresent prosecutors who have abused their right to investigate for political purposes. Then, what is necessary for the success of the high-ranking officials criminal investigation office? Above all, We think political neutrality is very necessary. The Ministry of Airborne has a very high authority of the Director. This paper intends to examine the functions and roles of the prosecution and high-ranking officials criminal investigation offices to prevent corruption. We analyzed the contents of the prosecution and the public officials criminal investigation office, and examined the limitations and problems, and the measures to control corruption in public offices.
