While many criminal studies have focused on the motivation of offenders and avoidance of victimization in the micro perspective, there have been a number of theoretical developments emphasizing space as a direct factor that influences the incidence of crime. The main purpose of this study is to analyze the effects of regional characteristics and violent crime incidence in Korea. Applying diverse spatial econometrics models that have less been utilized in the crime literature, this study finds an important association between spatial accessibility and crime incidence. The results suggest that the type of predominant business and the level of road accessibility affect the vulnerability of areas with respect to the incidence of violent crime. This study concludes with some important implications for urban planners and policymakers with respect to crime control and prevention.

This study is to investigate that population change as a result of the decline in population has a correlation with a decrease in crime, with the change in the demographic composition by comparing with two models: model with growth in population and one with the decline in population. We collected demographic data for all cities in Korea from the 2010 Census to 2020 offered by the Korean Statistical Information Service, with crime data comprising serious reported crime events from the Korean Nation Police Agency through requesting data related to the total number of crimes at the same as the period of demographic data. This study can identify the impacts of demographic changes as a result of population change on crime change through a comparative analysis between areas with population growth and ones with population decline. We can confirm that there are differences in determinants of crime between areas with population increase and one with population decrease from the analysis of the impact of demographic change as a result of population change on crime change.

Recently, as part of the crime prevention measures that focus on spatial characteristics on the determinants of crime-causing, interest in crime prevention (CPTED) through environmental design has been increasing. This study analyzed crime vulnerabilities in Ulju-gun for the purpose of establishing a master plan for crime prevention urban design (CPTED). The 12 indicators, including demographic, socioeconomic, and physical factors, were sampled from prior studies. As a next step, statistical analysis resulted in criminal vulnerability indexes. According to the analysis, districts with a high demographic crime vulnerability indexes were concentrated on apartment complexes, while districts with high socio-economic crime vulnerability indexes have low land prices and high proportion of female population. Also, the districts with high physical crime vulnerability indexes were found to be heavily distributed commercial ones with a large number of entertainment places. However, there was a limit to generalizing the indicators of previous studies to local governments with different regional characteristics. Therefore, further studies should be carried out by establishing additional indicators considering regional characteristics in the future.

This study examines the reporting factors of crime against business in Korea and proposes a corresponding predictive model using machine learning. While many previous studies focused on the individual factors of theft victims, there is a lack of evidence on the reporting factors of crime against a business that serves the public good as opposed to those that protect private property. Therefore, we proposed a crime prevention model for the willingness factor of theft reporting in businesses. This study used data collected through the 2015 Commercial Crime Damage Survey conducted by the Korea Institute for Criminal Policy. It analyzed data from 834 businesses that had experienced theft during a 2016 crime investigation. The data showed a problem with unbalanced classes. To solve this problem, we jointly applied the Synthetic Minority Over Sampling Technique and the Tomek link techniques to the training data. Two prediction models were implemented. One was a statistical model using logistic regression and elastic net. The other involved a support vector machine model, tree-based machine learning models (e.g., random forest, extreme gradient boosting), and a stacking model. As a result, the features of theft price, invasion, and remedy, which are known to have significant effects on reporting theft offences, can be predicted as determinants of such offences in companies. Finally, we verified and compared the proposed predictive models using several popular metrics. Based on our evaluation of the importance of the features used in each model, we suggest a more accurate criterion for predicting var.

The purpose of this study is to identify the determinants of planned behavior of adolescent, toward information security and cyber crime prevention. A survey methodology was used to investigate a proposed model of influence, and regression analysis was used to analyze the results. The hypothesized model was largely supported by this analysis, and the overall results indicate that the intention to actively participate in information security and cyber crime prevention is mostly influenced by the fear for cyber crime and the perceived usefulness of information security and cyber crime prevention activity. In addition, it was found that the perceived easy of use for information-security related ICT skill, fear for cyber crime, and social norm for information security influence the level of usefulness, but that the prior experience with information leaking was statistically insignificant factor to the level of usefulness and fear for crime. Useful suggestions for promoting information security and cyber crime prevention are also provided.

This study is to investigate determinants of the private security agents' career choices. Random sampling of newly agents working at the private security firms in Gyeonggi-do and ChungChong-do was used. The period of under review was from May, 2010 to June, 2011 and the total number of interviews was 382. For this study using SPSSWIN 18.0, factor analysis(EFA/CFA), reliability analysis, discriminant analysis and descriptive statistics. The followings are conclusions. The first factor is' the value of job'. It consists of public security, contributions to our society and nation, protection public safety, spirit of sacrifice, crime prevention, and maintenance security. The second factor is 'ease of career choice'. Qualifying conditions are not particular and it is easy to get the job, as a result, this job is easy of access, they chose this job. The third factor is 'occupational stability'. They think this is a good job because the job is future-oriented so they chose this job. The fourth factor is' curiosity'. They became interested in this job, so they wanted to know about this job and then they chose this job.

This literature review introduced the concept of psychopathy which has never been defined academically in Korea. Also it is reviewed how this concept could be applied as latent factor of criminal behavior in the forensic settings. For this purpose, first of all, the periodical change of psychopathy definition was explored. Then it was investigated which determinants might develop psychopathy and what would be the behavioral characteristics of psychopaths. Finally, risk assessment tools measuring psychopathy were introduced and their predictive efficacy and applicability in Korean criminal justice system was discussed.

The purpose of this research is to achieve qualitative growth for private security industry as a sector of service industry to attract clients and promote the growth of the private security industry by analyzing the factors which influence the customer's service satisfaction in using the private security services. A regression analysis was conducted to determine the factors which influences the satisfaction of private security service to ultimately achieve the research purpose. In the regression analysis, the difference between corporate clients and individual clients were analyzed for the sake of providing better security services and marketing applications. As a result, the factors that influences the satisfaction of the categorized groups were very clearly signified. Both individual and corporate clients showed increase in satisfaction rate when the fear of crime decreased. This result implies that the private security firms must possess segmented strategies as well as strategies to lower the fear factors of clients. There were no differences in all satisfaction-influencing factors when the fear reduction variable was exempted among both corporate and individual clients in usage satisfaction. This result shows that clients demand varies according to the client and the security firms must react to these demands by the clients. Although private security industry possess very clear publicity, it is a profit generating industry sector therefore, like other service industry, the private security services must implement strategies to keep up with the paradigm. If the satisfaction determinants from the research results are grafted into strategies such relationship marketing and target market selection, higher service satisfaction can be achieved from the clients.
