The purpose of this paper is to provide basic data for related studies by comparing and analyzing crimes committed by security guards through criminal statistical analysis, and to contribute to the sound development of the private security industry by strengthening the professional ethics of security guards and reducing guard crimes. The purpose. As a results of a comparative analysis of the number of crimes by security guards and the crime rate are as follows. Although the total number of crimes committed in Korea and the number of crimes committed by security guards decreased every year, the crime rate of security guards was higher than the average crime rate. felonious crimes, violent crimes, customs crimes, and special economic crimes were consistently high. As a countermeasure against the results, first, interest in security guard crimes as perpetrators rather than as victims, second, reinforcement of professional ethics education through new training and job training, third, academic development and systematic It appeared as a specification of the definition and current status of security guards for the study.

Reliability of the estimation is usually damaged in the situation where a linear regression model without spatial dependencies is employed to the spatial data analysis. In this study, we considered the conditional autoregressive model in order to construct spatial association structures and estimate the parameters via the Bayesian approaches. Finally, we compared the performances of the models with spatial effects and the ones without spatial effects. We analyzed the yearly total crime count data measured from each of 25 districts in Seoul, South Korea in 2007.

According to the document from the National Industrial Security Center in 2015, from 2003 to 2014 the disclosure number of industrial spy in South Korea was 438, and the damages due to the industrial technology leakages amounted 50 trillion won annually. Because the industrial technology leakage exercises great influence on the enterprises and the country. countermeasures against industrial technology leakages should be established. Therefore, the purpose of this research is to suggest measures preventing industrial technology leakages and related crimes in enterprises by applying the Crime Prevention Through Environmental Design(CPTED) technique. This research analyzed the recent technology leakage cases and used an analysis of literature research. From the result of this research, we suggested 1) Access Control, 2) Surveillance Enhancement, 3) Territoriality of Reinforcement, and 4) Activity Support by applying the CPTED technique for preventing industrial technology leakages. The limitations of this research and the recommendations for future research were discussed at the last part of this research.

The purpose of this study is to analyze the effects of CCTV installation empirically in the economic and spatial aspects(crime displacement and diffusion effects of crime control benefits), targeting S city in Korea. In terms of economic effects, caused by CCTV installation(2012 and 2013), cost benefit analysis was conducted by means of CCTV installation costs, crime cases, and crime costs per case. The result shows that there is positive effect of 1.34(34%) in 2012. This is slightly higher than the previous study results in Korea(cost effectiveness 1.32), but a little lower than the USA cases(cost effectiveness 1.49). In the case areas in S city, the result proves that the new CCTV has gained economic profit through the crime reduction, compared to the installation expences. However, the cases in 2013 shows no economic profit effect. Secondly, an analysis was conducted in the spatial aspect(crime displacement and diffusion effects of crime control benefits) by using the analysis tool of crime displacement value called WDQ. The results are summarized as follows: The total crimes in three regions had crime diffusion effect but it was less than the direct effect, while in one region, displacement effect was found, but they were less than direct effect. In the case of theft and violence, CCTV had a positive effect, except for one region. The results of the analysis were totally different. Judging from this difference, it may conclude that the effects of CCTV are different by the types of crimes and the places of crimes. The results of this study is meaningful in that it examined and evaluated the effects of the CCTV by scientific and rational measurement tools where previous studies are not many. In addition, it has policy implication for the validity of CCTV and making effective installation plan for crime reduction and prevention.

As an exploratory research to understand the nature of relationships between ports and their neighboring communities, this study analyzes how ports influence their residents' quality of life(QOL). The QOL was measured by 17 indicators reconstructed by reviewing relevant literatures. As a result, both Busan port and Dalian port were found to have statistically significant influence on many of QOL indicators including general expenditure per capita, number of manufacturing factories per capita, number of factories's laborer per capita, the rate of pavement, number of traffic accident per capita, rate of housing supply, number of financial agencies per capita, park area per capita, number of cultural assets per capita, the size of welfare expenditure per capita, number of fire occurrence per capita. And Busan port have statistically significant influence on QOL indicators including the rate of increase in population, number of public health industries per capita, number of public health industries per capita, number of schools per capita, number of sick-beds per capita, but Dalian port not have influence. Also Dalian port have statistically significant influence on number of crime occurrence per capita, but Busan port not have influence.
