Recently the violent crimes is the emerging social issue and the crime prevention is important policy both for maintenance of public order and the national welfare. To prevent these crimes with the geospatial data, we study the geospatial crime DB features, analytical method and linking method of current National Police Agency's crime system data. In this study, the Geospatial Information Open Platform(Vworld) was used to map the test site crime DB on the thematic map. We also researched the mesh-up thematic map and optimal location model of petrol car and CCTV.

유전자 감식법은 1980년대 후반에 미국에서 처음으로 법의학적으로 적용된 이래, 강력범죄, 친자확인 및 항공기 추락사고, 화재 등의 대형 참사의 신원 확인에 큰 공헌을 하였다. 유전자감식을 위해서는 높은 다형성을 보이는 STR (short tandem repeats) 좌위의 타이핑을 주로 이용한다. 한편, 최근 줄기세포 (stem cell)의 중요성이 인식되면서 폐기되던 제대혈의 보관 사업이 활성화되고 있다. 본 연구에서는 제대혈의 보관시 STR 타이핑의 유전 정보를 표기한 유전자 캐릭터를 동시에 제공하여 불의의 사고시 신원확인이 가능하게 하고, 아울러 이산가족에 대한 DNA정보 데이터베이스 구축 및 검색 프로그램을 개발하였다.

Since the sexual violence crime has a high probability of repeated crime, the electronic monitoring system has been introduced as a measure to it. And this system allows the police to know the location of former criminal around the clock through the electronic device, the former criminal has the psychological/mental oppression which can restrain the intention of crime to a degree. However, there is a limit in blocking criminals with strong will from repeated crime. The next-generation intelligent electronic anklet currently under study collects and analyzes the change bio-data in real time through the location information of electronic monitoring target and attached sensor. This study is aimed to predict the symptom of crime occurrence in advance based on this and block the crime intention in advance or stop the ongoing crime before it is expanded.

In recent years, the occurrence of life and violent crime in the city centered on crime-prone areas has become a big issue, raising the public interest in safety from crime has been higher than ever. As the initial response to crime and the importance of crime prevention are emerging, the government is preparing various measures such as crime prevention service using advanced technology. This project is a demonstration project to select specific target sites and apply that on a trial basis with the main purpose of commercialization of intelligent crime prevention technologies and services. In order to spread the business through the demonstration project, it is expected that the practical economic evaluation as well as the academic and practical value of the project will have a great significance. In this study, the purpose of this research is to derive economic feasibility through technologies and services to be implemented in Indokwon district of Anyang city, which is selected demonstration site of the intelligent security, to promote the spread of business and contribute to the policy activation.

최근 치안 관련 강력 범죄 발생이 사회 이슈화가 많이 된다. 이에 대한 해결책으로 CCTV가 기하급수적으로 보급, 설치되고 있다. 하지만 현재의 CCTV 기술은 단순 녹화의 수준에서 머물고 있기에 범죄 발생 사후에나 사용되고 있는 실정이다. 영상보안 분야에서 현재 진행되고 있는 지능형 영상 분석 기술은 영상 감시, 분석을 인력으로 사용하는 방식에서 벗어서 실시간으로 시스템에서 상황판단을 하여 경보하여 줌으로써 범죄의 예방 및 조속한 해결을 가능하도록 발전하고 있다. 본 논문은 지능형 영상 분석 시스템을 구성하는데 있어서 영상 분석 기술의 인터페이스를 공통화를 적용, 모듈화 함으로써 각각의 감시사이트에 적용 가능한 최적의 비전 기술 모듈만을 시스템 관리자에 선택에 따라 해당 시스템에 적용할 수 있도록 하였다. 또한 각 비전 모듈을 개별 프로세스로 동작하게 하고 모듈간의 통신을 네트워크화 함으로써 분산 환경으로 동작할 수 있도록 개발하였다.

다크웹을 통한 마약, 금융거래, 해킹 등 사이버 범죄가 증가하면서 다크웹 상의 범죄 추적을 위한 사이버 수사 필요성이 증대되고 있다. Tor와 같은 다크웹 접속 브라우저는 강력한 익명성을 제공하기 때문에 주로 다크웹 운영상의 취약점 분석, 악성코드를 활용한 함정수사 기법이 실효성 높은 다크웹 수사 기술로 간주된다. 그러나 사이트 개설 및 폐쇄가 빈번하게 발생하는 다크웹의 특성상 최신 범죄 정보를 수집하기 위해서는 방대한 다크웹 정보를 실시간 수집하고, 능동적으로 검색 키워드를 확장할 수 있는 고도화된 크롤러 기술 개발이 필요하다. 본 논문은 다양한 다크웹 사이트 중, 아동 음란물 사이트를 크롤링을 통해 수집하고, 수집된 텍스트의 연관 분석을 통해 검색 키워드를 확장하는 수집 체계를 제안한다.

Criminal profiling, also known as offender profiling is designed to predict the characteristics of unknown criminal perpetrator through an analysis of the crime scene. Until now, there has been conflict about the effectiveness of criminal profiling among academics. In this study, 113 police investigators', working in serious crime divisions, were interviewed about their experiences with criminal profiling, and their belief about its effectiveness. 63.7% of the respondents agreed that criminal profiling is a valuable investigative tool and 62.8% agreed that profilers are valuable to criminal investigations. A total of 31.8% agreed that profilers help the police identify offenders and 15.0% agreed that there is no risk of profiler misdirecting and investigation. 61.5% of the respondents who had reported using a profile agreed that profiling is helpful and 71.4% told that they would use profiling again in the future.

Purpose: The purpose of this study is to examine the path of money laundering of criminal proceeds through cryptocurrency using criminal script analysis and to devise measures to prevent and prevent criminal justice agencies from doing so. Method: Based on the results of a prior study on the profit path of cryptocurrency through money laundering and criminal cases in Korea, the path of money laundering was analyzed using criminal script techniques. Result: Most of the cryptocurrencies that have been launched are converted into criminal proceeds, which are re-launched and cashed or have a vicious cycle of being used as criminal funds are used. According to the script, the route of money laundering is mainly converted to criminal proceeds from cryptocurrency exchanges using anonymity, which is repeated several times, making it very difficult to find the money using cryptocurrency in criminal justice institutions. Conclusion: As the method of money laundering using cryptocurrency is becoming more sophisticated, legal sanctions and preventive institutionalization should be prepared for the prohibition or confiscation of cryptocurrency transactions for money laundering after understanding the flow.

We often find that we, as a social group, share stereotypes of criminals. For the present study we investigated the stereotypes of rapists, and examined if they match their characteristics on the national crime statistics in Korea. Collecting data from 82 college students and 91 police officers, we compared stereotypes about rapists with the characteristics of those reported on the national crime statistics. As a result, we found that both college students and police officers have distorted stereotypes of rapists which are not consistent with their characteristics. More specifically, both college students and police officers believed that rapists came from broken families and that they were likely to have more previous criminal convictions than they actually did. In addition, both college students and police officers believed that rapists tended to recidivate within a short period of time, e.g. 1-3 months, which is much shorter than the time that actually took for them to recidivate. Finally, suggestions for future research were made.

Due to the rapid developments of South Korea, local communities have faced various social pathologies which generated more violent crimes and criminalized younger students. Several horrendous violences, such as a Kangneung Girl assassination assault case in July 2017 and a Busan Girls assault case in September 2017, happened only between young students. This ignited a public uproar and people were more interested in related national policies and voiced for stronger penalties in ways that punish student offenders and abolish the juvenile law. In this respect, various effective policies are needed to prevent the school violence and to eliminate the students' fear of crime. These are expected to create an environment where students could enthusiastically study in a safe environment. Focusing on elementary school students, this study seeks to empirically analyse the effects of their perception of local crime control governance on their fear of crime and, subsequently, to suggest policy implications which could prevent future school violence and juvenile crimes and reduce the students' fear of crime. The results of this study are as follows: First, the analysis of the general fear of local crime control governance and the fear of crime showed that elementary school students' trust in police officers had a significant effect on the general fear. Second, the analysis of the local fear of crime control governance and the fear of crime highlighted that their trust in the police, social ties, intimacy between the police and residents had a significant effect on the specific fear. Therefore, this study is applicable in reality in that it can contribute to the prevention of school violence and reduction of fear of crime by constructing local crime control governance.
