In recent years, various crimes such as "random killing' crime continue to rise. Despite the government's crime prevention efforts and crime related researches, crime increases and a different approach is needed. Therefore, this study proposes the alternative for crime prevention by analyzing big data. To achieve this objective, this study was to perform visualization utilizing the histogram, the bubble chart and the hit map and association analysis. To analyze the relationship between crime and some variables, this study analyzed data of Seongnam city, Korea National Police Agency and etc. The results of analysis showed that CCTV will be to reduce the crime rate and security light is not significantly relevant. And the result showed that other types of crime focused by time of the day and day of the week and showed that an increase of the foreigners and crime increase are associated. This study presents a scheme for reducing the crime rate on the basis of this analysis result.

Crime prevention strategies are introduced to reduce the loss caused by crimes, and Target hardening against domestic burglary attacks is broadly accepted as one of such physical security strategies. In terms of business and home security, target hardening is one of the suite of protective measures that are included in crime prevention through environmental design(CPTED). This can include ensuring all doors and windows are sourced and fitted in such a way that they can resist forcible and surreptitious from the attack of intruder. Target hardening with certified security doors, security windows and secure locks are revealed to be much more effective to deter burglary attacks than other security devices, such as CCTV, lightings and alarms which have largely psychological and indirect impact. A pilot program of target hardening utilizing certified security window and locks was carried out in Ansan city, South Korea in 2016. This study is based on the quasi-experimental design of this program for a residential area. The researchers tried to verify the crime displacement effect of the target hardening program and the diffusion effects of crime prevention benefits by analysing the crime statistics. The evaluation utilized WDQ(Weighted Displacement Quotient) technique to analyze whether the crime displacement occurred, compared the crime statistics of the experimental area with that of buffer zone and controlled areas. The result showed that the target hardening program was significantly effective in crime prevention. The number of burglary in the experimental site with target hardening intervention reduced by 100%, although the areas without the intervention showed reduction in the burglary. The crime displacement was not found at all, and the number of burlary at the buffer zone also reduced significantly.

The current study applied the random forest algorithm to Korean crime victim survey data collected biennially between 2010 and 2018 to explore the relationship between crime/victim characteristics and the victim's criminal damages. A total of 3,080 cases including gender, age (life cycle stage), type of crime, perpetrator acquisition, repeated victimization, psychological damage (depression, isolation, extreme fear, somatic symptoms, interpersonal problems, moving out to avoid people, suicidal impulses, suicide attempts), and emotional changes after victimization (changes in self-protection confidence, self-esteem, confidence in others, confidence in legal institutions, and respect for Korean legal system/law) were analyzed. Considering the features of data that are difficult to apply traditional statistical techniques, this study implemented random forest algorithms to predict crime and victim characteristics using the victim's criminal damages (psychological damage and emotional change) and selected good predictors using VSURF function in VSURF package for R. As a result of the analysis, it was confirmed that the relationship between the type of crime and depression, extreme fear, somatic symptoms, and interpersonal problems, between perpetrator acquisition and somatic symptoms and interpersonal problems, and between repeated victimization and changes in respect for Korean legal system/law. Gender and life cycle stage (youth/adult/elderly) were found to be related to extreme fear and changes in self-protection confidence, respectively. However, more empirical evidence should be aggregated to explain the results as meaningful. The results of this study suggest that it is necessary to enhance the experts' knowledge and educate them on cases about the relationship between crime/victim characteristics and criminal damage. Strengthening their interview strategy and knowledge about law/rules were also needed to increase the effectiveness of the Korean victim assessment system.

Juvenile crime has recently severe problems in quality as well as great increase in quantity. Especially compared to adult crime, juvenile crime has higher recidivism rate, which leads to strong doubt about the limitations of existing treatment. This is because the correctional institutions have a bad influence on the juvenile criminal, that is not the original purpose like correction and edification, but relearning of crime. To prevent the recidivism of juvenile crime needs an active level in terms of the return as sound citizens through correction beyond a simple level of maintaining order. Correction welfare is one of the most important measures to prevent the recidivism of juvenile crime. This study examines the notion, types and trend of juvenile crime, considers the concept and functions of correction welfare, and shows the prevention of recidivism of juvenile crime in perspective of correction welfare.

The purpose of this study is to explore the relationship between housing types and crime and to suggest the appropriate strategies and interventions of housing policies for crime prevention. For spatial analysis of crime data, spatial autocorrelation is tested by Moran's I Test. A Ordinary Least Squares-based regression model is employed because crime data used in this study fails to show spatial autocorrelation. Results show that housing type variables except non-residential housing type are not associated with crime. Among land-use characteristics, the percentage of commercial areas is likely to better explain crime occurrence rather than housing types. It is surprising that residents' satisfaction to housing environment has a positive direction in its relationship with crime even though it cannot have a statistical significance. However, fear of crime shows a negative direction with crime although it fails to have a statistical significance. The findings of this study can contribute to understand the association between housing types and crime when setting housing policies for crime prevention.

매년 20여명 정도의 경찰이 자살에 이르고 있다. 업무량이 많은 타 공무원에 비해서도 높은 수준이다. 경찰의 자살에는 여러 가지 원인이 있지만, 특히 조직의 폐쇄성으로 인해 개인문제로 치부하는 경향이 높다. 경찰의 치안환경은 더욱 안 좋아지고, 위험성에 노출될 확률이 과거에 비해 높아졌으며, 잔혹한 범죄를 마주해야 하는 상황이 많아짐에 따라 우울증이나 업무부담 등으로 인해 자살을 하게되는 경우를 볼 수 있다. 따라서 경찰의 자살을 예방하기 위해서는 심리부검을 도입하는 방안을 법적으로 검도하고, 자살유형들을 분석하여 그에 맞는 자살예방모형 개발하여 자살률을 감소시킬 수 있는 방안을 모색해보고자 한다.

This study focused on the people harmed by violent offenders, especially by rubberies. Trends capture changes in victimization rates overtime, while patterns indicate connections between the attributes of victims and the frequency with which they are targeted. Data from the UCR and the NCVS indicate that many types of victimization are taking place less frequently since their peak years in the late 1980s and early 1990s. Cumulative risks indicate the odds of being victimized over the course of a lifetime. Differential risks underscore which categories of people are victimized more often than others.

This study focused on university students' risk perception of cybercrime through media exposure. For this purpose, I tried to figure out the results of risk perception on cybercrime with 8 factors. As a result, the lowest type of cybercrime was internet fraud, and it was caused by media type and degree of exposure, where university students get information about cybercrime. There's a difference of students' risk perception by media type, news media was the best. Depending on the media of the environment, even in the area of cyber crime there is a difference of perception of risk for each individual. And it can be confirmed that the risk perception in response to the exposure of the media has changed.
