The five major violent crimes including murder, robbery, rape·forced indecent act, theft, and violence are representative crimes that threaten the safety of members of society and occur frequently in real life. These crimes have negative effects such as lowering the quality of citizens' life. In the case of Seoul, the capital of Korea, the risk for the five major violent crimes is increasing because the population density of Seoul is increasing as a large number of people in the provinces move to Seoul. In this study, to reduce this risk, the relative risk for the occurrence of the five major violent crimes in Seoul is modeled using three spatio-temporal models. In addition, various risk factors are included to identify factors that significantly affect the relative risk of the five major violent crimes. The best model is selected in terms of the deviance information criterion, and the analysis results including various visualizations for the best model are provided. This study will help to establish efficient strategies to sustain people's safe everyday living by analyzing important risk factors affecting the risk of the five major violent crimes and the relative risk of each region.

The purpose of this study is to examine the spatial characteristics of violent and burglary crimes in South Korea. Violent crimes and burglary crimes depend on a spatial setting with good conditions for their criminal purposes. This study defines population density, racial heterogeneity, types of houses, and density of commercial facilities as variables of place affecting crime in cities and counties. The study collects data from 229 cities in Korea to analyze the effect of spatial characteristics on crime. We conduct additional analyses to meet the statistical requisites of the spatial econometrics model using the open-source software R and GeoDa 1.12.1.129. From the analytical result, population density, racial heterogeneity, apartments, and commercial areas relate to crime occurrence. We suggest the implication of the theoretical and practical contributions to the relationship between place and crime.

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.

This study aims to test the relationship between the change in population size and population composition and crime changes. The analytical model includes variables representing changes in population size and population composition, three dependent variables for crime changes, and three control variables. Changes in popuvpdllation size and population composition are measured by indicators such as population size, gender, age groups, and immigrants and foreign workers, and crime changes by felonious, burglary, and violent crime volumes. The sample includes 154 cities and counties in South Korea, and the sample period is from 2010 to 2017. As a result of the analysis, I examine that the decrease in the number of young and men are likely to lead to a decline in felonious and violent crimes, but a high rate of the elderly and the increasing racial heterogeneity are likely to accelerate the fear and worries about crimes.

The increasing trend of the five violent crimes (murder, robbery, rape, violence, theft) in Korea is not independent of social and economic factors. Several social science research have discussed about this issue but most of them do not properly reflect the nature of the time-series data. Based on several time series models, we studied about the endogenous factors (time, seasonal and cycle factors) and exogenous factors (economical, social change and crime control factors) on violent crime occur in Korea. Autocorrelation were also taken into account. Through this study, we want to help to make preventive policy by explaining the cause of violent crime and predicting the future incidence of it.

The purpose of this paper is to provide basic data for related studies by comparing and analyzing crimes committed by security guards through criminal statistical analysis, and to contribute to the sound development of the private security industry by strengthening the professional ethics of security guards and reducing guard crimes. The purpose. As a results of a comparative analysis of the number of crimes by security guards and the crime rate are as follows. Although the total number of crimes committed in Korea and the number of crimes committed by security guards decreased every year, the crime rate of security guards was higher than the average crime rate. felonious crimes, violent crimes, customs crimes, and special economic crimes were consistently high. As a countermeasure against the results, first, interest in security guard crimes as perpetrators rather than as victims, second, reinforcement of professional ethics education through new training and job training, third, academic development and systematic It appeared as a specification of the definition and current status of security guards for the study.

This study focused on the people harmed by violent offenders, especially by rubberies. Trends capture changes in victimization rates overtime, while patterns indicate connections between the attributes of victims and the frequency with which they are targeted. Data from the UCR and the NCVS indicate that many types of victimization are taking place less frequently since their peak years in the late 1980s and early 1990s. Cumulative risks indicate the odds of being victimized over the course of a lifetime. Differential risks underscore which categories of people are victimized more often than others.

Recently, our society has been changing its population structure due to low birth rate along with the extension of life span due to the development of medical environment and improvement of living environment. It was not long before the population became older, and the problem of the elderly was amplified by generational conflict. The current generation of senior citizens could not afford to prepare for their own retirement income due to their children's education, marriage and housing problems, and is a generation alienated from the benefits of public income security. In addition, not only are they in poverty with rapid industrialization, informatization and economic instability, but they are also threatened with livelihood. The increase in elderly crimes arising from the elderly, who are less adaptable to our society dominated by materialism, is being highlighted as a new social issue. In this study, we are going to analyze the causes of violent and violent senior citizens' crimes in quality along with quantitative growth, and present criminal situations and preventive measures using 10 years of data, judging that this is a time when a national response is needed through a social discussion on crimes committed by senior citizens in our society, where the pace of aging is unprecedentedly fast in the world In order to achieve this research objective, various opinions and statistical data of our society where the standards of senior citizens are changing were reviewed, and analysis of crimes was conducted on literature utilizing data of the Supreme Public Prosecutor's Office, the National Police Agency, and the National Statistical Office, recent press releases, and existing research materials. In this study, we will diagnose crimes committed by senior citizens in various aspects, including the characteristics of the elderly and the view of the elderly in the present society, and explore the direction of development for the prevention of future crimes as well.

This study reviewed literatures on crime victim support in Korea. KERIS, KISS and NANET were searched with "Victims of Crime Support" as keywords. In result, 314 were satisfied the eligible criteria for the review. The number of articles have steadily increased especially after the related law & policy were announced and after the outbreak of violent crimes. Among the research methods, qualitative studies appeared the most. Regarding the research topics, articles related to implementation of the law and policy ranked the highest in number. Among the type of crimes the number of sexual and domestic violence were reported the most. The number of studies on children and adolescent was shown with the highest frequency in minor groups. Finally, the psychological support appeared relatively low. This study suggests more empirical studies on psychological support for crime victims need to be administered as its future direction.

Congress enacted the sex offender registration and notification act in order to prevent sexual offenses and protect public safety in the U.S.. Namely, in 2006, the Jacob Wetterling Act and Megan's Law were integrated into the Adam Walsh Child Protection and Safety Act as a comprehensive sex offender supervision and management scheme. The AWA aims to eliminate loopholes and gaps formed by inconsistent state laws and statutes as well as to provide the federal standards for sex offender registration and notification. However, the AWA contains over-inclusive sex offender registration requirements and punishments. For this reason, the implementation of the AWA may cause problems for states, sex offenders, and citizens, both as taxpayers and as beneficiaries of the AWA. Therefore, the AWA that does not differentiate between violent and non-violent offenders should be reformed to allow law enforcement officials to focus on sex offenders convicted of violent and heinous crimes. That is, the AWA should not apply to sex offenders who are not dangerous, not likely to recidivate, and who committed non-violent crimes. In addition, because the AWA requires juvenile offenders to registrate on public notification forums, it may result in a greater risk to community safety and potential risk of reoffense. Accordingly, juvenile offenders convicted of non-violent sex offenses and not likely to recidivate will be provided appropriate treatments to be rehabilitated as members of community.
