This paper is dealing with the effectiveness to the crime prevention by the combined security system of the private security and the public security(the Police). In the western countries the public and the private security have well co-operated each other in terms of the job distribution. But our country's The private security has not much serviced in the crime prevention. The public security system has in limited capability to prevent the crime, therefore the co-production through with the private security industry and the community network are required to prevent and reduce the crime we are facing on. The followings are the result of survey on the prevention of crime through The combined security system(co-production) of The police, the private security and the community network; 1) The private security could be a big help to the police work if the two system can be co-operated smoothly. 2) The crime prevention could be not good worked out if police work would only be in the upper level class. 3) The job satisfaction is a positive if the co-operation between the police and the private security is on well.

This is a study on age-crime curve in Korea. Three data was used in this study as following: First is the crime statistics as aggregated data. Second is the police record(N=3.541 offences) of the male ex-offenders(N=988) who have been released in eleven prisons in 1987 as individual data. Third is the self-reported group-interview data(N=10.198 offences) administered to the male prisoners(N=979) in ten correctional facilities including eight adult prisons, one juvenile prison and one juvenile training center as another individual data. Generally, the right-skewness of age-crime curve has been explained through the difference of crime rate between early starters and late starters. Moffitt explains that this is because of the higher participation rate of the juvenile period of adolescence-limited offenders, but Godttfredson and Hirschi explain that this is because of a similar distribution in the crime rate of both early starters and late starters. the analysis of this study shows that Godttfredson and Hirschi’s explanation on the generality of age-crime-curve distribution is correct, but this can be modified by various factors like a economic crisis. And the peak age of juvenile period is consistent with the Moffitt’s hypothesis that the peak age is contributed to the increase of crime rate of late starters, not with Godttfredson and Hirschi’s one.

The interest in the prevention of sex crimes and social secure is growing as the number of cases by sexual offences becomes higher. Although various punishable ways have been introduced so far, increasing sex crime is still going on. Thus, effectiveness of legal systems for preventing crimes is questionable. More recently, the approach for environmental criminology has been paid attention for reducing criminal opportunities through environmental design and management of crimes. This study attempts to look over the spatial distribution of sexual crimes in the context of environmental criminology, and examine the correlation between regional environmental factors and the occurrence of sexual crimes empirically. To do this, we visualized the map for sex crimes at the macro-scale and explored the spatial distribution of sexual crimes and spatial clusters based on various spatial statistics using sex crime data published online by the ministry of gender equality and family. Also, we derived the environmental characteristics of sexual crimes by multivariate regression analysis on a large number of explanatory variables of regional environment. Our results will help to understand the current situation and spatial aspects of sex crimes in the nation more realistically. Further, it is respected that our results might be useful basic information for establishing regional policies and plans for the prevention of the sexual crime and enhanced public policing.

통계청에 의하면 65세 이상 인구가 2024년 1,000만명을 도래할 것으로 예측하고 있으며, 노인인구 증가와 함께 노인치안 이슈들은 매년 증가하고 있다. 특히, 경찰청 자료에 따르면 최근 5년간 노인범죄피해는 매년 증가하고 있는 것으로 나타났다(경찰청, 2021). 치안서비스 대상에서 주요한 영역을 차지하게 될 노인을 대상으로 한 범죄예방정책을 마련하기 위하여 범죄피해노인의 특성에 관한 연구를 함에 있어 연도별 노인의 범죄피해영향요인의 차이가 있는지를 이 연구에서는 분석하고자 하였다. 따라서 이 연구에서는 한국형사·법무정책연구원의 2014년, 2016년, 2018년 전국범죄피해조사 2차 자료를 활용하였으며, 그 중 만65세 노인대상 자료만을 추출하여 2014년 1.921명, 2016년, 2,935명, 2018년 2,707명을 각각 최종분석에 활용하였다. Spss ver 21. 통계프로그램을 활용하여 로지스틱회귀분석을 실시하였으며, 연구결과 2014년에는 사회적 무질서 수준과 노인범죄피해와의 관계성이 높았다면, 2016년에는 물리적 무질서 수준과 노인범죄피해와의 관계성이 높았고, 2016년과 2018년에는 독거노인과 빈 집으로 가구가 노출되는 시간이 긴 정도가 노인범죄피해와의 관계성이 높은 것으로 볼 수 있었다. 이러한 연도별 노인 범죄피해 영향요인의 변화를 실증연구를 통해 검증함으로써 추후 노인범죄예방을 위한 정책마련의 자료로 활용하고자 한다.

공공기관에서 발간하는 공식통계자료들을 살펴보면 대부분 관찰값으로 총 빈도수나 또는 전체를 기준으로 하여 그 빈도수가 차지하는 퍼센트 그리고 지수 등으로 나타나 있다. 이러한 자료는 단순히 공무원들에게 행정용으로 활용되고는 있으나 일반인들이 자료를 이해하고 나아가 활용하기는 어렵다. 이런 자료들이 일반인을 위한 자료가 되기 위해서는 국민 한사람(또는 기본 단위)당 그 발생 확률을 구하여 제시하고 나아가 개개인의 여러 복잡한 현실 상황을 고려해도 그 확률 계산이 용이하도록 기초적인 자료를 제공하는 것이 바람직하다고 사료된다. 즉, 육하(六河)원칙을 근거로한 현상에 대하여 확률을 구하고 활용할 수 있는 방안을 제시한다. 이 논문에서는 경찰청에서 발표된 교통사고에 대한 통계자료와 대검찰청에서 발표된 범죄사건 통계자료를 통계학의 기본인 확률의 개념을 도입하여 보다 이해가 쉽고, 나아가 교통사고와 범죄 피해를 최소한으로 줄일수 있는 자료로 변환하여 설명하고자 한다.

In this paper, we proposed and implemented a crime prediction algorithm based upon crime influential factors. To collect the crime-related big data, we used a data which had been collected and was published in the supreme prosecutors' office. The algorithm analyzed various crime patterns in Seoul from 2011 to 2013 using the spatial statistics analysis. Also, for the crime prediction algorithm, we adopted a Bayesian network. The Bayesian network consist of various spatial, populational and social characteristics. In addition, for the more precise prediction, we also considered date, time, and weather factors. As the result of the proposed algorithm, we could figure out the different crime patterns in Seoul, and confirmed the prediction accuracy of the proposed algorithm.

The aim of this study is to specifically understand the characteristics of the crime by empirical analysis for the determining factors that affect determining the crime through the space syntax in Busan. In this study, poisson regression and negative binomial regression were used for accurate analysis. 8 variables that were significant of the total 13 variables. The summary if this study based on the results is as follow. Statistically significant variables are female ratio, over 65 population ratio, administration are and commercial area ratio in characteristics. And the more CCTVs a region has, the lower crime rate it shows. As a results of examing whether space syntax variables can predict crime occurrence places. Space with low connectivity come to be a crime causal factor because they have few other related spaces and thereby have low possibility of sudden appearance of interrupters, which results in low surveillance levels of foot passengers. It will provide the basic data that can contribute to urban planning and implementation of crime prevention aspects.

The spatial distribution of crime incidences in urban neighborhoods is a reflection of their socio-economic environment and spatial inter-relations. Spatial interactions between offenders and victims lead to spatial autocorrelation of the crime incidences. The spatial autocorrelation among the incidences biases the interpretation of the ecological model in OLS framework. This research investigates residential crimes using residential burglaries and robberies occurred in the city of Columbus, Ohio, for 2000. In particular, the spatial distribution of incidence rates of residential crimes are accounted in OLS framework using eigenvectors, which reflect spatial dependence in crime patterns. Result presents that handling spatial autocorrelation enhanced model estimation, and both economic deprivation and crime opportunity are turned out significant in estimating residential crime rates.

Online game industry and item trade have grown up fast after 2000. And there has been a perspective that online game and item trade are the cause of the crimes, especially cyber crime like hacking, virus. But there was no positive research about the opinion, so this article studies the relations among online game, item trade and crime. The results suggest that online game and item trade maybe a cause of cyber crime and property crime. But online game and item trade don't increase the total number of crime. That means that online game and item trade substitute the way how crime happens. Online game and item trade substitute no-property crime to property crime.

익명 네트워크 기술에 기반한 다크웹은 일반 표면웹보다 더 강화된 익명성을 제공한다. 최근 이 익명성을 악용하여 다수의 다크웹 사용자들이 다크웹 내에서 범죄 행위를 모의하는 행위가 꾸준히 발생하고 있다. 특히, 국내 다크웹 사용자들은 마약 유포를 위한 방법을 공유하거나 성착취물 유포 행위 등에 직간접적으로 가담하고 있다. 이와 같은 범죄 행위들은 수사 기관의 눈을 피해 현재까지도 계속해서 발생하고 있어 국내 다크웹 범죄 동향 파악의 필요성이 증대되고 있다. 그러나 다크웹 특성상 범죄 행위를 논의하는 게시글을 수집하기가 어렵고, 다크웹 내에서의 언어 사용 특성에 대한 이해 부족으로 그동안 다크웹 사용자들이 어떤 내용의 범죄를 모의하는지 파악하기가 어려웠다. 본 논문에서는 국내 사용자들이 활동하는 다크웹 포럼들을 중심으로 사용자들의 언어 사용 특성을 연구하고, 이를 통해 다크웹에서 다뤄지는 범죄 유형들을 분석한다. 이를 위해, 자연어처리 기반의 분석 방법론을 적용하여 다크웹에서 공유되는 게시글을 수집하고 다크웹 사용자들의 은어와 특정 범죄군에서 선호되는 언어 특성을 파악한다. 특히 현재 다크웹 내에서 사용자들 사이에 관측되는 어휘들에 대한 기술통계 분석과 유의어 관계 분석을 수행하였고, 실제 다크웹 내에서 사용자들이 어떠한 범죄에 관심이 많은지를 분석하였으며, 더 나아가 수사의 효율성을 증대시키기 위한 소셜미디어, URL 인용 빈도에 대한 연구를 진행하였다.
