The number of CCTV installed in Korea is over 1.3 million, increasing by more than 15% annually. However, due to the limited budget compared to the installation demand, the infrastructure is composed of 500,000 pixel low-quality CCTV, and there is a limits on identification of objects in the video. Public CCTV has high utility in various fields such as crime prevention, traffic information collection (control), facility management, and fire prevention. Especially, since installed in high height, it works as its role in solving diverse crime and is in increasing trend. However, the current public CCTV field is operated with potential problems such as inability to identify due to environmental factors such as fog, snow, and rain, and the low-quality of collected images due to the installation of low-quality CCTV. Therefore, in this study, in order to remove the typical low-quality elements of public CCTV, the method of attenuating scattered light in the image caused by dust, water droplets, fog, etc and algorithm application method which uses deep-learning algorithm to improve input video into videos over quality over 4K are suggested.

주민의 안전한 생활은 삶의 가장 기본적인 요건으로 범죄는 불안감이 가중되어 삶의 질을 저하시키는 주요 요인이라 할 수 있어 범죄예방을 위한 다양한 정책 중 환경설계를 통한 범죄예방(CPTED)의 필요성이 대두되고 있는 실정이다. 따라서, 지역사회 커뮤니티 형성, 범죄예방 정책 수행 및 각종 인프라 구축 등을 위한 범죄예방 도시디자인 가인드라인 수립이 필요한 것으로 판단된다.

The prospect of security services industries is as followings. First, integrated security system will be increased in the security service sphere of collective housing such as apartments. Second, the needs to security services with high-tech electronic security system and systematic security service against crimes will be increased. Third, the needs to crime prevention and disaster prevention service including information security service by means of internet and information and communication technology will be increased. Fourth, perhaps domestic market of security service will be reshaped in relation with localization trend and entrance of foreign security service companies to our country. With these conclusions I think that the departments of universities related to security services will focus on their social roles.

While the progress of preparation for the 2002 World Cup games goes on the environment is changing by industrializations development of science and specialization of technology, because of that recently the crime has also became intellectual so the importance on countermeasure of safety has raised. The countermeasure for safety The stadium is a limited space where amount of population could be concentrated, so that in a moment there could be a great casualties by terrorism, specially there should be efficient countermeasures for bomb terrorism. So to be prepared for the problems that had been appeared on bomb terrorism activities of North Korea around the world, we should know about the inspection environment and special inspection environment, and for the prevention first of all I've studied on suitable way to inspect the stadiums secondly to plan on specialized training of the necessary personnel on inspection and finally efficiency of use on inspection equipment. With there following plans we could make perfect safety countermeasures focused on prevention for the successful World Cup games.

The study, recognizing the seriousness of such second-convictions of sexual violence offenders and supplementing the problems noticed from an integral electronic monitoring anklet, which only offers simple location information, would like to propose a Prevention System against Second-Convictions of Sexual Violence Offenders by using Smart Electronic Monitoring Anklet. Proposed System is anticipated to be able to prevent second-convictions of sexual violence offenders as the data of offenders from Smart Electronic Monitoring Anklet with various sensors and the data from Integrated DB of Judicial Authorities is comparatively analyzed, allowing anticipative actions at each stage based on the analyzed data regarding sexual violence.

In the era of the 4th Industrial Revolution, the importance of data is intensifying, but there are many cases where it is not easy to use data due to personal information protection. Although criminal justice information is expected to have various useful values such as crime prediction and prevention, scientific investigation of criminal investigations, and rationalization of sentencing, the use of criminal justice information is currently limited as a matter of legal interpretation related to privacy protection and criminal justice information. This study proposed to convert criminal justice information into 'crime data' and use it as big data through the structuralization and categorization of criminal justice information. And when using "crime data," legal issues, value in use, considerations for data generation and use were verified by experts, and future strategic development plans were identified. Finally we found that 'crime data' seems to have solved the privacy problem, but it is necessary to specify in the criminal justice information related law and it is urgent to be organized in a standardized form for analysis to use big data. Future directions are to derive data elements, construct a dictionary thesaurus, define and classify personal sensitive information for data grading, and develop algorithms for shaping unstructured data.

Recently emphasizing the importance of security such as national major institutions' facilities or major industrial facilities for the maintenance of security/crime prevention due to specialization of the Green Information Technology(G-IT) and Green Ubiquitous Technology(G-UT) industry fields, The Security System Building linked high technology within the government-related organization, enterprise and army the military is urgently required. This paper is about the green USN intelligent an unmanned guard MUX system that receive the signals, from alarm device within surveillance area, with various ways of communication techniques and then transmit to local control center and remote control server trough TCP/IP network. This study enables the mutual senergy effect by realizing a total solution of an unmanned guard system and also significantly contributes to the global/domestic market expansion. That can be applied to the crime prevention/security fields in the Green Ubiquitous Environment Implemented Business(survalance-Home, Gu-City, Gu-Health, etc.), and will contribute to expand companies with international competitiveness that can provide the Green Ubiquitous Vision(Gu-Vision).
