The library is the most frequently utilized building on campus, but, it has been reported to be a facility most vulnerable to crime. However, almost no study has been conducted on crime in the library, which implies a need for research on the subject. The purpose of this study is specifically twofold. First, this study will suggest components of environmental plan to prevent fear over library crime on campus. Second, the study seeks to reveal the correlation between use per library space and fear of crime. This has been analyzed by conducting a survey among current university students, and the survey includes the following three details: first, fear over day/night crime per library space; second, components of environmental plan to prevent fear over crime per library space; third, level of use per library space on campus. The results of study show that fear of crime has low relation with crime occurrence, fear per library space is higher during the night than during the day, and the space where the fear level is usually high is the service facility. There is a difference for each space in terms of important components of environmental plan to prevent crime per library space, and installation of security device is most important. One must consider a plan for a crime safe environment regarding library space where the level of use during the day is low.

This paper was conducted to prevent and respond to crimes by predicting crimes based on artificial intelligence. While the quality of life is improving with the recent development of science and technology, various problems such as poverty, unemployment, and crime occur. Among them, in the case of crime problems, the importance of crime prediction increases as they become more intelligent, advanced, and diversified. For all crimes, it is more critical to predict and prevent crimes in advance than to deal with them well after they occur. Therefore, in this paper, we predicted crime types and crime tools using the Multiclass Logistic Regression algorithm and Multiclass Neural Network algorithm of machine learning. Multiclass Logistic Regression algorithm showed higher accuracy, precision, and recall for analysis and prediction than Multiclass Neural Network algorithm. Through these analysis results, it is expected to contribute to a more pleasant and safe life by implementing a crime prediction system that predicts and prevents various crimes. Through further research, this researcher plans to create a model that predicts the probability of a criminal committing a crime again according to the type of offense and deploy it to a web service.

Since the 1950s, crime prevention was to figure out how dissident. Unlike traditional crime prevention was a point of view. Physical environment and a method to prevent crime, "Crime Prevention Through Environmental Design (Crime Prevention Through Environmental Design: CPTED)" is the prevention of crime, property crime, criminals and human right with the surrounding environment. These CPTED has a variety of factors. Natural surveillance of these is the most basic elements. Natural surveillance is monitored by monitoring the behavior of criminals, to prevent crime. CPTED was the large majority of existing studies focused on a study area. However, this study examined the area around a house. Made to secure the hypothesis of natural surveillance to affect fear of crime. Research on fear of crime and crime victimization declined. Thus, the securing of natural surveillance proved to be effective in crime prevention in this study.

Modern society, various great strength crimes are producing. After all crimes happen, it is most important that prevent crime beforehand than that cope. So, many research studied to prevent various crime. However, existing method of studies are to analyze and prevent by society and psychological factors. Therefore we wishes to achieve research to forecast crime by time using Markov chain method. We embody modelling for crime occurrence estimate by crime type time using crime occurrence number of item data that is collected about 5 great strength offender strength, murder, rape, moderation, violence. And examined propriety of crime occurrence estimate modelling by time that propose in treatise that compare crime occurrence type crime occurrence estimate price and actuality occurrence value. Our proposed crime occurrence estimate techniques studied to apply maximum value by critcal value about great strength crime such as strength, murder, rape etc. actually, and heighten crime occurrence estimate probability by using way to apply mean value about remainder crime in this paper. So, we wish to more study about wide crime case and as the crime occurrence estimate rate and actuality value by time are different in crime type hereafter applied examples investigating.

Juvenile crime has recently severe problems in quality as well as great increase in quantity. Especially compared to adult crime, juvenile crime has higher recidivism rate, which leads to strong doubt about the limitations of existing treatment. This is because the correctional institutions have a bad influence on the juvenile criminal, that is not the original purpose like correction and edification, but relearning of crime. To prevent the recidivism of juvenile crime needs an active level in terms of the return as sound citizens through correction beyond a simple level of maintaining order. Correction welfare is one of the most important measures to prevent the recidivism of juvenile crime. This study examines the notion, types and trend of juvenile crime, considers the concept and functions of correction welfare, and shows the prevention of recidivism of juvenile crime in perspective of correction welfare.

This study tries to find the possibility to prevent crime by improving urban spatial environment through the analysis of spatial environment property that mutually coincides or differs by comparing the place where crime actually occurs and the place where citizen is afraid of crime. The method of study is as follows. First, the ontents scope and method of study was established by theoretic investigation of case study related to crime. Second, as crime cannot be prevented by police power only, CPSCP(Citizen Participation System for Crime Prevention) was developed so that all citizen can cooperatively participate in the crime prevention anytime and anywhere. Third, the data on the place where people feel fear in the region was collected by directly indicating the place where citizen is afraid of crime in the space by utilizing CPSCP. Fourth, the place where crime actually occurs and the place where citizen is afraid of crime are redundantly analyzed for comparative analysis of 2 places. The result shows that environmental design improving physical environment of urban space is necessary to prevent crime and to eliminate the fear of crime. The CPSCP developed by this study which will be advanced to U-crime prevention system will contribute to making citizen's own neighborhood a smart safety city autonomously.

In this study, we proposed GIS-based Regional Crime Prevention Index (RCPI) development method designed to support local governments with systematic crime prevention activities. The public interest in safe urban environment is increasing rapidly. The government is putting efforts into crime prevention activities to eliminate the criminal opportunities in advance. CPTED is method to prevent crimes in the city by improving environmental factors that cause crime. It is used by local governments to promote the crime prevention activities centering on the expansion of CCTVs and street lamps and the improvement of street environment. However, most policies were terminated as one-off programs and it is necessary to monitor the effect of such policies on a continuous basis. In order to alleviate issues, this study proposed RCPI as part of crime safety assessment in urban environments. The estimation of RCPI in City A of Gyeonggi-do showed relative differences in 31 districts (dong), indicating that it is also possible to evaluate the crime safety in the local community on the level of the administrative dong, the smallest administrative district in the urban environments. As a crime map, the RCPI will be used effectively as he reference to support the decision making process for local government in the future.

Due to the rapid developments of South Korea, local communities have faced various social pathologies which generated more violent crimes and criminalized younger students. Several horrendous violences, such as a Kangneung Girl assassination assault case in July 2017 and a Busan Girls assault case in September 2017, happened only between young students. This ignited a public uproar and people were more interested in related national policies and voiced for stronger penalties in ways that punish student offenders and abolish the juvenile law. In this respect, various effective policies are needed to prevent the school violence and to eliminate the students' fear of crime. These are expected to create an environment where students could enthusiastically study in a safe environment. Focusing on elementary school students, this study seeks to empirically analyse the effects of their perception of local crime control governance on their fear of crime and, subsequently, to suggest policy implications which could prevent future school violence and juvenile crimes and reduce the students' fear of crime. The results of this study are as follows: First, the analysis of the general fear of local crime control governance and the fear of crime showed that elementary school students' trust in police officers had a significant effect on the general fear. Second, the analysis of the local fear of crime control governance and the fear of crime highlighted that their trust in the police, social ties, intimacy between the police and residents had a significant effect on the specific fear. Therefore, this study is applicable in reality in that it can contribute to the prevention of school violence and reduction of fear of crime by constructing local crime control governance.
