This paper aims to analyze fear of crime which is considered socio-psychologically important in our daily lives from a geographical point of view. Especially, the spatial patterns of the fear of crime which were analyzed in the area of Youngtong in Suwon city. First, this paper takes a look at the correlation between the incidence of crime and the fear of crime. Most people feel fear in actual crime scenes, but they do not always coincide with place where people feel the high level of fear. Fear of crime is closely connected with physical environments as well as the incidence of crime. The level of fear is high in places where the light is dark, unfrequented paths, especially in parks and around mountains. Several factors which have effects on fear of crime operate differently upon place. Second, a survey which measures the fear of crime was quantitatively analyzed. Factor analysis was employed to find out whether questions are appropriate for measuring the fear of crime as well as to reduce the amount of data so that more exact result can be derived from the data. Through the factor analysis, seven factors were extracted and it is found that a factor of incivility accounts for 24.032% of variance. Other factors which affect fear of crime are community cohesion, warning, incidence of crime, victimization, morality and authority.

인물의 행동 및 이동을 인식하는 것은 다양한 분야에서 활용될 수 있다. 사람의 행동을 파악하여 니즈를 예상하고 맞춤형 콘텐츠를 제공하거나 행동을 예측하여 범죄나 폭력을 예방하는 등 여러 방면으로 활용 가능하다. 그러나 이동과 현재 위치 정보만으로 인물의 행동을 예측하기에는 한계가 있다. 본 논문에서는 실시간으로 사람의 이동과 행동을 인식하기 위해 Kinect v2가 제공하는 관절 정보와 YOLOv3를 이용하여 실시간으로 사람의 행동을 인식하는 시스템을 제작하였다.

This study is for the analysis of the influence that the factors(communication, domestic life, offensive action, economic problem) of marital conflicts of old age and ecological systems factors(individual, family, sociality) have a impact to the divorce of elderly(thoughts and attempts of divorce) and the impulse to commit a crime(violence, egoism, running away from home). The guinea pigs is 350 married people of ages greater than 55 in the capital area. The 338 collected data excluding incomplete 12 data were analyzed. Statistical methods used in this study were factor analysis, frequency analysis, reliability analysis, t-test, ANOVA, Hiearchical regression analysis and Scheffe test with SPSS 18.0. The result are as follows. First, the marital conflict and ecological systems have a severe impact to the divorce of elderly, the more the conflict of the domestic life and the offensive action, the conflict in communicative and economic problem are getting higher. Second, the marital conflict and ecological systems have a severe impact to the impulse to commit a crime, the more the conflict of a domestic life and the conflict caused by spouse's attack, the economic problem, the egotistic impulse are getting higher. Third, there are some statistically similar differences of all the parts(sex, academic ability, job, children coresidence, religion, physical condition, monthly average income) in the marital conflict by characteristic of sociology of population, ecological systems, the divorce of elderly and the impulse to commit a crime.

In order to examine the type of PAI profile for criminally charged juvenile offenders, the study sought to find out personality types and behavioral characteristics of 251 juvenile offenders and 173 ordinary adolescents from 2018-2020. Looking at the overall profiles of juvenile offenders and ordinary adolescents, we found differences in Infrequency(INF), Mania(MAN), Antisocial Features(ANT), Alcohol problems(ALC), Drug problems(DRG), Aggression (AGG), and Dominance(DOM) and Warmth(WRM). Based on these results, we perform clustering as factors Antisocial features(ANT), Aggression(AGG), and Dominance (DOM) with an average difference of more than five points. It was classified as Cluster 1 with a high percentage of adolescents and Cluster 2 with a high percentage of juvenile offenders, and Cluster 1 was named as a defense group because it showed a similar model to the profile of ordinary adolescents. The profile type of cluster 2 was named externalization, which can be represented as an externalization group. The results were similar to previous studies, and the profile type of juvenile offenders has higher overall clinical scale than that of ordinary adolescents, indicating behavioral problems. Continued research on juvenile offenders could lead to understanding of youth as well as juvenile offenders.

스마트관제 시스템은 딥러닝 서버내 학습된 백본 네트워크 모델이 실시간으로 스트리밍 되는 CCTV 영상으로부터 이상행동 패턴을 선별적으로 탐지하고 관제요원에게 전달하여, 사전에 사건사고를 예방하거나 즉시 대응 체계의 유연한 운영을 가능케하는 시스템이다. 최근 지능형 CCTV(Closed Circuit Television) 서비스가 일부 지역에 선별 관제의 형태로 시범적으로 운영되고 있는 상황이다. 지능형 시범서비스는 공공 영역에서 선별 CCTV 관제의 형태로 이상행동 상황을 즉각 인지하여 사건사고를 예방하거나 피해를 최소화하고자 하는 목적으로 주로 사용되고 있다. 그러나, 범죄 등의 특정 시나리오에만 한정해서도 이상 행동 유형이 너무나 다양하기 때문에 이상행동 영상의 사전분류(Annotation)를 통해 딥러닝 모델을 학습시키는 것이 현실적으로 어려운 상황이다. 따라서 본고에서는 최신 이상 행동 탐지(Anomaly detection) 알고리즘과 응용사례를 분석하여 실제 현장에 적용할 수 있는 현장 중심의 기법을 제안하고자 한다.

The purpose of this study was to examine the response pattern of children of early childhood (ages 4 to 5) to strangers' luring behaviors that suggest imminent crime. Data were collected from registrants offered by four kindergartens and daycare centers. Individual interviews were performed (N = 100) by using a questionnaire. Results were as follows: First, children of early childhood responded unfavorably to strange adults' kindness and request for aids. However, it was found that they did not make the right decision in relation to strange adults' luring behaviors that lead to crime when family related clues were manipulated. Second, children of early childhood responded favorably to strange adults' luring behaviors that are suggestive of criminal intent when candy, ice cream, and toys were offered. Especially, youngsters were more prone to be deceived by these indices than the older children. Third, older children responded unfavorably to strange adults' luring behaviors that suggest a criminal intent In addition, youngsters did not respond cleverly to strange adults' luring behaviors that suggest a criminal intent while showing a reluctant response.

최근 범죄 예방을 위해 감시영상에서 폭력행위 검출에 대한 영상 분석 기술의 요구가 증가하고 있지만 지금까지의 폭력행위 검출 기술은 영화 또는 YouTube의 폭력장면 검출에 초점이 맞추어져 있다. 영화에서 촬영된 폭력 장면에는 주로 피를 흘리는 모습들이 자주 등장하기 때문에 색상 특징을 이용한 알고리즘을 많이 사용하였다. 하지만 실제 CCTV에서 촬영된 폭력행위는 피가 묻은 장면이 자주 발생하지 않기 때문에 영화 속 폭력장면 검출 알고리즘과는 차별성이 있어야 한다. 본 고에서는 국내외 폭력 행동 분석에 대한 기술 동향을 살펴보고 감시영상에서의 폭력 행동 검출하는 기술에 대해 살펴보고자 한다.

In this paper, abnormal behavior monitoring system using YOLO AI platform was implemented and had superior response characteristics compared to the conventional monitoring system using two-shot detection by using one-shot detection of YOLO system. The YOLO platform was trained using image dataset composed of abnormal behaviors such as assault, theft, and arson. The abnormal behavior monitoring system consists of client and server and can be applicable to smart cities to solve various crime problems if it is commercialized.

This article assesses the recent police reform strategy in England and Wales with the Police Reform and Social Responsibility Act 2011. Police and Crime Commissioners have a responsibility not just for the police force but also for reducing crime in their area of responsibility. This ensures that their remit runs much more widely than their predecessor body, the police authority. The article goes on to evaluate the nature and extent of crime by making immediate use of survey of local police commanders. The surveys showed that police commands were swamped with minor crime and anti-social offences. The arrival of Police and Crime Commissioners has meant that now police priorities can be more closely aligned to those of the public and where anti-social behaviour is now recognised as impacting on the lives of many residents more significantly than criminal activity. The article highlights the changes introduced by government following the Winsor Review to police pay, pensions and conditions of service. It reflects on the impact of this on both police morale and professional motivation. It suggests that current government policy is now haemorrhaging the police service as increasing numbers of experienced officers are leaving the police service which could ultimately undermine its long-term resilience as a strategic emergency service.
