오늘날 자살은 현대사회의 심각한 사회현상으로 인식되고 있다. 자살에 대한 역사적 이해와 성경의 자살 이야기들을 간략하게 다룬 다음 자살의 원인을 살펴보게 될 것이다. 자살문제에 대한 해법을 제대로 찾기 위해 반드시 필요한 것은 그 원인이 무엇인지에 대한 올바른 이해가 선재되어야 하기 때문이다. 학자들의 견해는 대략적으로 생물학적 원인, 정신과적 원인, 그리고 사회학적 원인 세 부류로 나눠진다. 논자의 주요 논지는 자살을 이런 요인들이 복합적으로 작용한 결과로 발생한다는 것이다. 이에 대한 해결책으로 성경의 생명존중을 기초로 한 세 가지 사실을 제시한다. 첫째, 하나님의 형상으로 창조된 인간의 생명은 고귀하다. 둘째, 인간은 궁극적 의미에서 영원한 생명이라는 희망의 미래를 조망해야 할 존재이다. 셋째, 자살은 범죄행위라기보다는 치료가 필요한 질병이라는 인식의 확산이 필요하다.

이동 통신 단말기 가입 시 타인의 명의를 도용하여 가입하고 사용요금을 내지 않는 피해 사례가 지속적으로 발생하고 있으며 명의도용 휴대폰이 범죄에 사용되는 등 매우 우려할 만한 일이 발생되고 있다. 이러한 이동통신의 역기능에 대처하기 위하여 2005년 5월부터 모바일 안심 서비스(M-Safer)라고 하는 명의도용 방지 시스템이 가동되고 있다. M-Safer 서비스의 그 동안의 효과 또는 운영성과를 둘러싼 각 이해 당사자들 간의 시각차이가 커 논란이 되고 있다. 본 연구에서는 이러한 시각차이가 발생된 원인이 무엇이며 IT서비스로서 진정한 의미의 명의도용방지(M-Safer) 서비스 도입의 효과가 무엇인지에 대해 검토해 보고 앞으로의 개선 방안에 대한 건설적 제안을 하고자 한다.

본 논문에서는 감시시스템이 갖추어진 환경 내에서 발생할 수 있는 특이 행동을 효율적으로 감지하기 위한 기법을 제시한다. 최근 대형 범죄 및 방화 사건 등의 방지목적으로 DVR 의 단순 녹화를 벗어나 지능형 감시시스템을 도입하려는 연구가 활발히 진행되고 있다. 그러나 이러한 시스템들은 아직 초기 연구 단계에 있으며 영상내의 관심물체 추출을 위한 전경과 배경의 분리 및 추적 단계에 그치고 있다. 이에 본 논문에서는 가우시안 혼합 모델을 통하여 전경과 배경을 분리하고, 관심영역에 한해서 Optical Flow 기법을 이용하여 폭력상황과 같은 특이 행동의 감지 여부를 판단 할 수 있는 방법에 대해 실험을 통해 평가하였다.

범죄 예방과 자원 보호를 위해 CCTV 카메라를 이용하는 방범 시스템의 필요성은 점차 커지고 있다. 아날로그 형식에서부터 디지털 형식으로 발전된 형태의 방범 시스템이 개발되고 사용 중이지만, 비용이 높고 효율성이 떨어지는 문제가 있다. 본 논문에서는 웹 서비스 기반의 서버에 적외선 카메라를 연결하고 사용자가 사전 인지 없이도 클라이언트에서 실시간으로 침입을 탐지하여 적절하게 대처할 수 있는 방범 시스템을 설계하고 구현한다.

When most examining judges deny the request for an arrest warrant, they cite (as a reason) that there is no worry about escape or the destruction of evidence. Consequently, there has been no knowing what characteristics of a crime mainly affect the decision for an arrest warrant and there has been significant dispute about the exact decision criteria used for an arrest warrant. This paper classified the data about the request of arrest warrants for crimes committed in the jurisdiction of the Jinju Public Prosecutors' Office in 2006, 2007 and 2008, into 7 categories according to characteristics of the crimes. For each category we construct a statistical model about the decision on arrest warrants by applying a crosstabulation analysis in order to look for the characteristic of crime that affect the decision for an arrest warrant.

Continue to have an increasingly violent crimes against children every year, and as you know all seriousness is classified as a felony. However, efforts to reduce the underlying crime is low. Therefore, it is necessary to solve this problem, the security system. Is to protect the children and adults that exist that can pose a threat to children to identify and monitor tracking method in this paper. Was based on a Korean standard body size of a person, such as keys, arm length, leg length, head vertical length, head width proposed method. Also, separate the adults and children through the comparison of the reference value, the ratio and the ratio of the number of pixels of the detected object, the proposed method. Processing speed is fast because it detects only a specific object region in the entire image in the handling method in the proposed method the five nine minutes. The advantage is to enable comparison of the specific object, through which there is.

The purpose of this paper is to analyze various categories such as the recognition, expectation and acceptability of CCTV use in educational facilities by doing a survey on how college students think about the CCTV installed in educational facilities. For this research, diverse existing surveys regarding CCTV were examined, and the appropriate elements of survey questions were extracted and developed. Based on this method, we intend to complete a survey study hereafter on the change in perception regarding CCTV inspection. We made four hypotheses before the survey and the results of the survey are as follows: First, the expectations for CCTV's ability to reduce crime were high. Second, the fears about being a victim of theft or violence crime were decreased. Third, there were a number of respondents who would weigh more on increased safety by installing a CCTV rather than be concerned that CCTV may lead to the violation of students' human rights. Fourth, there showed a difference in recognizing CCTV among three groups. Also, for the questions regarding the places where CCTV is installed, there were many negative opinions on its installation in the student convenient facilities. What we have achieved was not a simple survey which investigates the pros and cons about CCTV use, but a newly suggested way of survey, which enables us to test various hypotheses and figure out the changing perceptions on CCTV effectiveness in educational facilities with more efficiency.

The purpose of this study is to exploratively examine factors affecting walking at night anxiety among the elderly. Study sample for the analyses was 9,120 persons aged over 65. Factors affecting walking at night anxiety among the elderly were composed of sociodemographic factors, health-related factors, and social perception factors. Sociodemographic factors include gender, age, region, education, having or not having a spouse, household income. Health-related factors include walking ability, vision, subjective health status, cognitive function. Social perception factors include perception about other's compliance with laws and perception about safety from crime. The main results of the analyses are as follows. Among sociodemographic factors, factors that had significant effects on walking at night anxiety among the elderly were gender, age, region, education. Among health-related factors, factors that had significant effects on walking at night anxiety among the elderly were walking ability, vision, subjective health status, cognitive function. Among social perception factors, factors that had significant effects on walking at night anxiety among the elderly were perception about other's compliance with laws and perception about safety from crime. Results of this study show that there is a need for multiple methods to make safe and comfort walking environment for the elderly.

The number of CCTV installed in Korea is over 1.3 million, increasing by more than 15% annually. However, due to the limited budget compared to the installation demand, the infrastructure is composed of 500,000 pixel low-quality CCTV, and there is a limits on identification of objects in the video. Public CCTV has high utility in various fields such as crime prevention, traffic information collection (control), facility management, and fire prevention. Especially, since installed in high height, it works as its role in solving diverse crime and is in increasing trend. However, the current public CCTV field is operated with potential problems such as inability to identify due to environmental factors such as fog, snow, and rain, and the low-quality of collected images due to the installation of low-quality CCTV. Therefore, in this study, in order to remove the typical low-quality elements of public CCTV, the method of attenuating scattered light in the image caused by dust, water droplets, fog, etc and algorithm application method which uses deep-learning algorithm to improve input video into videos over quality over 4K are suggested.

The purpose of this research was to identify the relationship between specific personality characteristics and maladaptive social behaviors in order to contribute to development of a pragmatic intervention for the prevention of sexual aggression. This was accomplished by examining the mediating effects of entitlement rage (K-PNI) or sociosexuality (K-MSAS) on sexual aggression, and moderating effects of cognitive emotion regulation strategies (K-CERQ) or state empathy (K-CMEM) on sexual aggression in narcissistic men. Data were obtained from male college students (n = 264) who completed self-report questionnaires, such as K-NPI and K-CMEM, and hierarchical regression analysis was applied to examine these relationships. Both entitlement rage and cognitive emotion regulation strategies were found to be unassociated with sexual aggression. Rather, sociosexuality was the mediating factor between narcissism and sexual aggression, Whereas state empathy was a moderating factor between narcissism and sexual aggression. These findings indicate a tendency for sociosexuality to increase sexual aggression in males. However, individuals with low state empathy are more likely to show sexual aggression than those with high state empathy, indicating that intervention for increased state empathy may be a more effective treatment than cognitive emotion regulation strategies.
