In the modern society, people live in an environment while sharing a space with each other and secure their own space for the safety. As interest in "Crime Prevention Through Environmental Design (CPTED)" securing the safety of citizens from crime through environmental design is increasing, this research studies the public space design realized in public environments which is explored through the understanding of the concept of public design. Through the various case studies conducted with the concept and cases of public design, a standard for proceeding with crime prevention design has been established. The research analyzes the results of successful cases with ten extracted keywords, and finally three design solutions for crime prevention were proposed through extracted keywords. Each design solution was evaluated by 25 CPTED researchers who participated in this project with Likert's 5-point scale. Based on final evaluation results, the research will further investigate better and safe approaches and solutions for CPTED.

The purpose of this study is to propose the calculation model of CCTV monitor size for school. Literature review analyzed the concept and technical characteristics of CCTV system including equation of object size calculation. Case study showed that the sizes of CCTV monitors installed in the security offices of the six object schools were 19 inches on average. And the numbers of monitor screen partitions were at least 12 on average. Due to too many partitions in small monitors of approximately 19 inches, the faces of the objects of filming in each screen could not be properly identified. Experimental test presented that the vertical length of face image clearly recognized on the screen is at least 20mm. Based on the result, this paper developed the equation for calculating monitor size. Pilot test said that 27inch Monitor is needed for 4 screens. The practitioners of school districts and schools can make appropriate CCTV system environments considering the their own CCTV system conditions.

This study started with necessity of historical spatial planning skills in U-city planning. Though U-city technology and information are very important, U-city development should be considered on the base of various experience of spatial planning. This study explored spatial planning indexes change in the recent newtown plans. In particular, safety and security were intensively analyzed. In addition, many theories on safe urban space, ubiquitous technology, traditional defensible space, and CPTED (Crime Prevention through Environmental Design) are compared. The findings are as follows. First, each planning is not integrated and there is lack of network among each planning. Specifically, from the crime prevention perspective, there is only mechanical monitoring such as CCTV without architectural approach. Even though CCTV is social needs, it is necessary to adopt it with architectural environment in order to improve the synergy effect of spatial planning and non-spatial planning.

Flat or Multiple Dwelling Houses are relatively vulnerable to crime safety. Crime prevention measures are urgently needed because crime is 2.6 times higher than in real apartments. Through the analysis of domestic and foreign crime prevention design standards, field survey, and interviews with experts, 27 items of crime prevention design criteria for flat or multiple dwelling house were derived, and ten design criteria that should be considered first by the expert AHP were derived. As a result of the pilot evaluation of existing flat or multiple dwelling house, the houses completed after 2015 have relatively high level of crime prevention, but the houses constructed before that are very vulnerable. The policy and system improvement plan based on the analysis result is as follows. First, new housing should be promoted to meet minimum criteria by supplying and educating public officials, architects, and building owners in the short term to provide criteria for flat or multiple dwelling house crime prevention plans. Second, existing housing should be supported with basic crime prevention support projects such as security windows for flat or multiple dwelling house where security of residential environment such as urban renewal policy is poor. Third, the Enforcement Decree of the Building Act shall be revised to make the crime prevention environment design of flat or multiple dwelling house obligatory, and the criteria of flat or multiple dwelling house crime prevention plan should be reflected in the notice of crime prevention building standard.

Burglary (also called breaking and entering and sometimes housebreaking) is a crime, the essence of which is illegal entry into a building for the purposes of committing an offence. It is one of the most common types of crime and also a serious issue for every society. A house that is left insecure is an accessible and attractive target for burglars and therefore burglary resistance test & certification system for doors and windows has been developed in many countries. This paper explores several advanced foreign burglary resistance test/certifcation cases (the British SBD, the Dutch KOMO SKH/SKG, the Japanese CP mark, the Australian Standard Certification) for security products and domestic test/certification systems for fire safety products as a comparative study so that any improvement points can be gained for South Korea in the field of security product performance. The comparative analysis results show that South Korea is far behind the security product certification system and needs a lot of improvement in the system by benchmarking foreign cases. The domestic test/certification systems for fire safety products also give some insights for burglary-related security products' performance certification system in Korea. Overall, the need for relevant rules and regulations, the establishment of standards regarding testing and certification, including certified security +hardware product in building security certification system, performance testing as well as production testing (i.e. quality management system evaluation), the basic competency of testers, incentive system for certified/high quality security products were suggested in order to make an optimal model for the security production performance testing and certification system in Korea.

In recent years, crime has been steadily increasing, causing not only economic damage but also aggravating the social atmosphere. The CPTED(Crime Prevention Through Environmental Design) guideline, which is an environmental crime prevention design technique, reduces the possibility of crime by implementing a proper defensive design plan through appropriate lighting design in the city and reduces the fear of crime. Among the various principles of CPTED, the proper use of street lamps and CCTV is considered to be an important factor in enabling natural surveillance. In this study, the authors identified and quantified the current status of the installation of street lamps and CCTV in each autonomous district of Seoul. The physical quantity of lighting and social factor quantified from light lamps and CCTV data, respectively, were expected to support the guidelines presented by CPTED. Therefore, we conducted statistical analysis based on quantified values and found that street lamps and CCTV had a statistically significant relationship with crime rate. In addition, the correlation between the safety index and the crime rate, calculated by dividing the number of street lamps and CCTVs by area, was also analyzed and an R2 value of 0.647 was confirmed.

In recent days, school violence has been rising as a significant social problem. The occurrence of school violence can be fueled by a wide range of social and environmental contexts, thus it is very difficult to come up with the ultimate solution. Community CPTED program is one of the more comprehensive set of efforts that has been developed to prevent crime in general, and the primary focus of the study is to investigate suitable components of CPTED to prevent school violence based on the physical conditions of communities as well as the perception of residents outside of school grounds, in the vicinity of schools. Three sets of analyses in series were employed in the research. First, Ward's minimum-variance cluster analysis was used to classify the places where school violence can occur outside of school grounds based on the physical conditions recognized by local residents. Next, Importance-Performance Analysis was performed to analyze the perception of local residents about the importance and the effectiveness of CPTED components in preventing school violence. Subsequently, Ordered Logit Model was used to analyze the local residents' awareness on safety regarding school violence in their community space. Combining the results of the analyses, the priority of the community CPTED applications to prevent school violence outside of school was derived. Reflecting the local residents' perception on safety of students in their community, the sense of security in communities against school violence can be reinforced by the communities' sensible efforts in creating safer environment for their students.
