The study aims to examine the effects of crime on societal anxiety. For this purpose, two studies were conducted. In study 1, the data were collected from 286 students(male 160, female 126) regarding perceived seriousness of crime, estimation of crime occurrence, societal anxiety, and estimation of change in these 3 variables every 3 years from 1993 to 2011. The means of the 3 variables were higher than the midpoint of the scale. And the means of all the 3 variables gradually increased from 1993 to 2011 and the change patterns were very similar. Furthermore, the estimation of crime occurrence and perceived seriousness of crime were significant predictors of societal anxiety. Study 2 was conducted to explore the effect of frequency estimation of the criminal acts on the societal anxiety. The data from 259 subjects(male 141, female 118) were analysed. The occurrence of frequency of 7 types of crimes including 25 criminal acts were estimated and societal anxiety was measured. The results of study 2 showed that only the major crime was significant a predictor of societal anxiety, and among the major crimes, arson was a significant predictor of the dependent variable. Implications and limits of the studies are discussed.

In recent years, the number of scams related to voice phishing has been on the decline, but the number of messenger phishing attacks, a new type of crime, is increasing. In this study, by analyzing SNS posts containing messenger phishing cases, criminal trends of the main methods, imposture of trusted relative and fake payment were identified. Through the analysis, main words and patterns composing the message and the similarity and continuity of the phone numbers used were derived as criminal attributes, and criminal organizations were grouped. As the results of the analysis, we propose a cooperative system to prevent damage from messenger phishing by disseminating the criminal information collected by investigative agencies to private operators, and a plan to respond to messenger phishing predicted through grouping of criminal organizations.

최근 데이터의 양이 급격하게 증가하면서 빅데이터의 시대가 도래했다. 빅데이터는 형식이 없는 비정형 데이터이므로 기존의 정형 데이터 처리 방법으로는 분석 및 데이터 처리가 불가능해졌다. 또한, 범죄예방에 대한 관심이 증가하면서, 범죄 데이터 분석의 수요가 증가하고 있다. 본 연구에서는 비정형 범죄 데이터를 분석, 예측 등의 전산처리를 하기 위한 정규화 메트릭을 설정하는 방안을 제안하고자 한다.

CCTV는 범죄상황 발생시 보안과 증거확보를 위해 사용되어 왔다. 그러나 실제 상황에서 범죄가 발생하기 전 예방을 하는 것 보다 사후 처리에 용도를 두고 있으며, 범죄 예방의 목적에 대해 미미한 효과를 보이고 있다. 본 논문에서는 CCTV로 수집된 보행자의 데이터를 통해 객체의 행동을 분석하여 위험도로 행동의 위험여부를 추정하기 위한 Flexible Multi-level Regression 모델을 제안하였다. 제안된 모델을 통해 관찰된 객체의 행동이 이상행동이라고 판단될 시 위험을 받는 객체에게 알림을 주어 범죄 발생 전 즉각적인 대응이 가능하며 빠른 상황판단이 가능할 것으로 예상된다.

The current study applied the random forest algorithm to Korean crime victim survey data collected biennially between 2010 and 2018 to explore the relationship between crime/victim characteristics and the victim's criminal damages. A total of 3,080 cases including gender, age (life cycle stage), type of crime, perpetrator acquisition, repeated victimization, psychological damage (depression, isolation, extreme fear, somatic symptoms, interpersonal problems, moving out to avoid people, suicidal impulses, suicide attempts), and emotional changes after victimization (changes in self-protection confidence, self-esteem, confidence in others, confidence in legal institutions, and respect for Korean legal system/law) were analyzed. Considering the features of data that are difficult to apply traditional statistical techniques, this study implemented random forest algorithms to predict crime and victim characteristics using the victim's criminal damages (psychological damage and emotional change) and selected good predictors using VSURF function in VSURF package for R. As a result of the analysis, it was confirmed that the relationship between the type of crime and depression, extreme fear, somatic symptoms, and interpersonal problems, between perpetrator acquisition and somatic symptoms and interpersonal problems, and between repeated victimization and changes in respect for Korean legal system/law. Gender and life cycle stage (youth/adult/elderly) were found to be related to extreme fear and changes in self-protection confidence, respectively. However, more empirical evidence should be aggregated to explain the results as meaningful. The results of this study suggest that it is necessary to enhance the experts' knowledge and educate them on cases about the relationship between crime/victim characteristics and criminal damage. Strengthening their interview strategy and knowledge about law/rules were also needed to increase the effectiveness of the Korean victim assessment system.

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.

The purpose of this study is to examine the impact of callous-unemotional traits(CU) on juvenile crime and explore additional effects of parenting and socioeconomic status on juvenile crime. A total of 103 juvenile probationers completed self-report questionnaires at 3 probation offices in Seoul, and a total of 123 high school students completed self-report questionnaires in Seoul and Gyeonggi. The results of this study were as follows. First, juvenile crime group showed higher score in uncaring subscale of CU, lower parent's education and lower economic level than normal group. Second, in both groups, uncaring subscale of CU showed negative correlations with parent's acceptance and daily monitoring. Third, in logistic regression, uncaring subscale of CU and low economic level significantly predicted juvenile crime group. This study suggests that uncaring characteristic of CU and socioeconomic status are potential factors contributing to juvenile crime.

This study is trying to analyse the correlation between the crime behavior and the social alteration or development. Capitalism reposes on economic competition, and the impact of capitalism is according to crime behavior. Then the type of crime and the diversity of crime are transformed by the social environment and the social development. So this study is divide into 3 parts. The first is the correlation between industrialized and crime. It means that the industrialized is accompanied with the urbanized and arouse a material desire, these social phenomenon are a high correlation with increase of violent behavior and the crime. The second party is explain and analyse the correlation between the information and the crime. The information causes other type crime by contrast with the industrialized age and society. If the industrialized has caused the violent behavior and the crime, the information is too clever by half and break out the crime in the companionship of innumerable unspecifiness. So, the crime of the information age is a very wide scope and casualties, especially has a concealment of crime. And the third party describe in conclusion the social alteration and the extension of crime. Social alteration or social development is according to economic development. Competitive economic development include many complication and friction in a society, these factors are expressed in various crime. In the result the occurrence and the type of crime is a high correlation between the social alteration or development.
