Various Kinds of social pathology and crimes that threaten our daily safety are on the increase in process of time as a result of the development of science and technology empty of moral sense, Value Confusions, apolaustic tendency, economic and social transformation recently. Moreover the effective provision of police service lies beyond the boundaries of the police organization. Therefore private security personnel have made an effort for safety and protection of group as well as an individual through the introduction of private security industry based on a benefit principle and private security industry is being become complexes utilizing technology as well as high-end devices through various international events. The field of private security industry in Korea is being extended rapidly with expansionism of society and public services but the quality improvement is declining. Furthermore the study of recruit education program for security personnel as the basis of quality improvement is insufficient compared with the study of police service. Consequently, this investigation is going to contribute to development of recruit education program for security personnel through the analysis about difference of each subject usability for education about electronic security and facility guard.

This study focuses on the prediction and factors of apartment prices in Seoul using a convolutional neural networks (CNN) model that has shown excellent performance as a predictive model of image data. To do this, we consider natural environmental factors, infrastructure factors, and social economic factors of the apartments as input variables of the CNN model. The natural environmental factors include rivers, green areas, and altitudes of apartments. The infrastructure factors have bus stops, subway stations, commercial districts, schools, and the social economic factors are the number of jobs and criminal rates, etc. We predict apartment prices and interpret the factors for the prices by converting the values of these input variables to play the same role as pixel values of image channels for the input layer in the CNN model. In addition, the CNN model used in this study takes into account the spatial characteristics of each apartment by describing the natural environmental and infrastructure factors variables as binary images centered on each apartment in each input layer.

Terrorism has existed in the entire human history and has become a significant topic in criminology while prior studies has focused on North Korea as the perpetrator, and this prevents an in-depth discussion of the international trends of terrorism. As soft targets are the main target of new terrorism and because we never ignore the significance of the consequences, there are needs for more studies on the topic. This study conducted a case study of major terrorism attacks and surveyed professionals in the field via an AHP analysis in order to find the characteristics of terrorism and its potential patterns in South Korea. As a result, we found that North Korea or the left-wing may utilize homemade bomb, motor vehicle or drone for the purpose of attacking multi-use facilities in South Korea. For policy implications, we insist developing a better CPTED approach on those facilities, improving professionalism of cyber-watchdog via more training and education, stricter control on drone permit, and operation of counseling centers for preventing radicalization.

The subway, which is an urban railway, is the core of public transportation. Urban railways are always exposed to serious problems such as theft, crime and terrorism, as many passengers use them. Especially, due to the nature of urban railway environment, the scope of surveillance is widely dispersed and the range of surveillance target is rapidly increasing. Therefore, it is difficult to perform comprehensive management by passive surveillance like existing CCTV. In this paper, we propose the implementation, design method and object recognition algorithm for intelligent object recognition system in urban railway. The object recognition system that we propose is to analyze the camera images in the history and to recognize the situations where there are objects in the landing area and the waiting area that are not moving for more than a certain time. The proposed algorithm proved its effectiveness by showing detection rate of 100% for Selected area detection, 82% for detection in neglected object, and 94% for motionless object detection, compared with 84.62% object recognition rate using existing Kalman filter.

The causes of the fire casualties were the heat burns, contacted by flame, before the period of industrialization. According to the economic has been developed drastically since 1990, residing space has been become bigger and sophistication and interior finishing materials have been diversified. Therefore, the suffocation casualties, caused by inspiration of toxic combustion gases, have been more increased than the flame casualties in recently. Also, the arson casualties have been increasing with the increasing of insurance crime to take the Insurance money. According to National Emergency Management Agency announcement, 31,778 fires was occurred nationwide in 2006 and the total casualties were 2,180 occurred. 446 persons were died among them. Because the exact investigation of fire, occurred the death, is very especially important that civil and criminal cases will be happened. Therefore, we studied about the cause of fire, the place of origin, and the group of casualties age on the axies of fires, which were occurred recently. And the identification method of fire casualties, the human behavior characteristic, the flame casualties and the suffocation casualties at fire scene.

Communication log data consist of communication events such as sending and receiving e-mail or instance message and visiting web sites, etc. Many countries including USA and EU enforce the retention of these data on the communication service providers for the purpose of investigating or detecting criminals through the Internet. Because size of the retained data is very large, the efficient method for extracting valuable information from the data is needed for Law Enforcement Authorities to use the retained data. This paper defines the Interactive Communication Sequence Patterns(ICSPs) that is the important information when each communication event in communication log data consists of sender, receiver, and timestamp of this event. We also define a Mining(FDICSP) problem to discover such patterns and propose a method called Fast Discovering Interactive Communication Sequence Pattern(FDICSP) to solve this problem. FDICSP focuses on the characteristics of ICS to reduce the search space when it finds longer sequences by using shorter sequences. Thus, FDICSP can find Interactive Communication Sequence Patterns efficiently.

Objective : This study aims to identify personality characteristics in female homicide offenders by using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) test. Methods : This study retrospectively analyzed the mental appraisals and MMPI-2 scores of 54 women charged with homicide and 67 women charged with non-violent crimes, who were referred to National Forensic Hospital in Gongju city for psychiatric evaluation between January 2012 and March 2016. Results : Women charged with homicide scored significantly higher on Hs (p=0.018), D (p<0.001), Hy (p=0.002) and Pt (p=0.004) than the women charged with non-violent crimes. The women charged with homicide may have developed the following characteristics: hypochondriasis, depression, hysteria and psychasthenia. In multiple regression analyses, a final regression model including age of crime onset and depression was significant, explaining 16.5% of the variance in homicides committed by females. Conclusion : These findings suggest that personality characteristics in the female homicide offenders might be different compared to the non-violent crime offenders.

본 연구의 목적은 노동력의 사회적 특성적인 면에 있어서 각기 다른 산업에 종사하는 노동력의 "누가" "어떻게" 변화해 가는가에 중점을 두면서 한국의 산업 각 부분간의 변천과정을 조사하는 데 있다. 이 연구에는 1960, 1970, 1980년에 실시된 한국 센서스 자료가 주로 사용되었다. 본 연구의 결과에 따르면 1960년과 1980년 사이의 한국의 산업 구조적인 면에 있어서의 급속한 변화를 보여주고 있다. 그러한 변화들은 주로 경제발전 정책과 더불어 농촌지역에서 도시지역으로의 인구이동에 기인된다고 하겠다. 예를 들면 1960년에 65%의 노동력이 1차 산업에 종사한 반면에 1980년에는 38.5%로 감소했고 이와는 대조적으로 1960년에 오직 8.7%의 노동력이 2차산업에 종사하던 것이 1980년에는 27.6%로 증가하였다. 3차 산업 역시 1960년에 23.8%에서 1980년에 33.9%로 10%의 증가를 보였다. 경제.발전이 이루어지는 과정에서 실업자들이나 잠재 실업자들이 경제활동에 참여할 수 있었기 때문에 경제구조 자체가 예전에 비해 더 안정이 되고 생활수준도 향상이 되었다고 하겠다. 이러한 결과는 부분적으로는 계속된 5개년 경제개발 계획에 기인된다고 할 수 있다. 경제발전 과정에서의 대도시로의 인구집중, 특히나 2차 산업과 3차 산업이 집중되어 있는 서울로의 인구집중은 주택, 교통, 범죄등 많은 문제를 낳고 있다. 동시에 도시지역에의 과잉 노동력의 존재와 농촌지역에는 특히나 농번기에 노동력 부족현상을 야기시키고 있다. 시간의 흐름에 따라 여성노동력의 비율, 전문직과 사무직 종사자, 그리고 서비스분야 종사자들의 비율이 증가하였는 데 비해 대부분의 다른 국가에서 처럼 한국에 있어서도 자영인의 비율은 경제발전 과정에서 감소하였다. 경제발전과 더불어 보다 전문화되고 조직화된 시장중심의 생산체제가 가구와 지역사회 중심의 생산기능을 흡수하므로서 많은 노동력이 임금 노동자가 되었다. 특히나 단순노동을 통한 많은 젊은 여성들을 고용하는 제조산업 분야에서 여성들이 낮은 임금과 과로 그리고 나쁜 작업환경으로 인하여 그들의 건강을 해치고 직업병을 유발할 가능성이 많다고 하겠다. 지난 20년에 걸친 급속한 정부 주도형의 경제발전은 노동력의 제 산업 간의 급속한 변천과 더불어 긍정적인 측면과 부정적인 측면을 모두 낳았다고 할 수 있겠다.측면을 모두 낳았다고 할 수 있겠다.

As cyber attack methods are becoming more intelligent, incidents such as security breaches and international crimes are increasing. In order to predict and respond to these cyber attacks, the characteristics, methods, and types of attack techniques should be identified. To this end, many security companies are publishing security intelligence reports to quickly identify various attack patterns and prevent further damage. However, the reports that each company distributes are not structured, yet, the number of published intelligence reports are ever-increasing. In this paper, we propose a method to extract structured data from unstructured security intelligence reports. We also propose an automatic intelligence report analysis system that divides a large volume of reports into sub-groups based on their topics, making the report analysis process more effective and efficient.
