Based upon the first national sample of adult men and women, the study aims to examine the prevalence of chid sexual abuse in Korea and factors related to the incidence of child sexual abuse. The results of the study show that 20.8% of the sample experienced one or more types of sexual abuse in their childhood, which indicates that Korean society is not any longer immune to child sexual abuse. With regard to how to cope with sexual abuse, "not informed to anyone and did not get any help at all" is the most major one for all types of sexual abuse. Even those who got help were reported to depend heavily upon private routes such as parents, relatives, or friends, indicating the urgency of establishing systematic intervention schemes for the problem. The results of a logistic regression analysis show that gender of the child, involvement in delinquent behaviors, economic status of the family, number of siblings, and residence in high-crime region are significantly related to the incidence of child sexual abuse. These results of the study would be expected to provide a useful guideline for developing policies or intervention programs aimed to prevent or address child sexual abuse.

The advent of digital media has facilitated easy access for adolescents to environments conducive to the purchase of narcotics. In particular, there's an increasing trend in the purchase and consumption of narcotics mediated through Social Network Services (SNS) and messenger services. Adolescents, sensitive to such environments, are at risk of experiencing neurological and mental health issues due to narcotic addiction, increasing their exposure to criminal activities, hence necessitating national-level management and support. Consequently, the quest for sustainable treatment methods for adolescents exposed to narcotics emerges as a critical challenge. In the context of high relapse rates in narcotic addiction, the necessity for cost-effective and user-friendly treatment programs is emphasized. This study conducts a literature review aimed at utilizing digital platforms to create an environment where adolescents can voluntarily participate, focusing on the development of therapeutic content through art. Specifically, it reviews societal perceptions and treatment statuses of adolescent drug addiction, analyzes the impact of narcotic addiction on adolescent brain activity and cognitive function degradation, and explores approaches for developing digital therapeutics to promote the rehabilitation of the addicted brain through analysis of precedential case studies. Moreover, the study investigates the benefits that the integration of digital therapeutic approaches and art therapy can provide in the treatment process and proposes the possibility of enhancing therapeutic effects through various treatment programs such as drama therapy, music therapy, and art therapy. The application of art therapy methods is anticipated to offer positive effects in terms of tool expansion, diversification of expression, data acquisition, and motivation. Through such approaches, an enhancement in the effectiveness of treatments for adolescent narcotic addiction is anticipated. Overall, this study undertakes foundational research for the development of digital therapeutics and related applications, offering economically viable and sustainable treatment options in consideration of the societal context of adolescent narcotic addiction.

According to the Annex 17 to the Convention on International Civil Aviation, an appropriate authority of each contracting state has to define and allocate tasks and coordinate activities between the departments, agencies and other organizations of the State, airport and aircraft operators and other entities concerned with or responsible for the implementation of various aspects of the national civil aviation security programme. The airport has to take leading role in implementing security tasks at airport area because the airport operator is the provider of airport facilities and services to its customer and the security activities belong to its services. So Republic of Korea Government enact the Law, Aviation Safety and Security. The Purpose of this Act is to prevent any unlawful act in airport facilities with international conventions, including the ICAO to provide for standards, procedures and mandatory matters needed to ensure the safety and security of civil aviation. But the Act has some error. So is this paper to review the revision of aviation security regulation and the changes of aviation security responsibilities and task assignment. There is the term "aviation security personnel", who are charged with the task of preventing any act of disrupting the order and safety in airport. But there is no term "security screening personnel" who performs to detect or search for dangerous object, such as weapons or explosives, which may be used for the unlawful obstruction.

Recidivism prediction has been a subject of constant research by experts since the early 1970s. But it has become more important as committed crimes by recidivist steadily increase. Especially, in the 1990s, after the US and Canada adopted the 'Recidivism Risk Assessment Report' as a decisive criterion during trial and parole screening, research on recidivism prediction became more active. And in the same period, empirical studies on 'Recidivism Factors' were started even at Korea. Even though most recidivism prediction studies have so far focused on factors of recidivism or the accuracy of recidivism prediction, it is important to minimize the prediction misclassification cost, because recidivism prediction has an asymmetric error cost structure. In general, the cost of misrecognizing people who do not cause recidivism to cause recidivism is lower than the cost of incorrectly classifying people who would cause recidivism. Because the former increases only the additional monitoring costs, while the latter increases the amount of social, and economic costs. Therefore, in this paper, we propose an XGBoost(eXtream Gradient Boosting; XGB) based recidivism prediction model considering asymmetric error cost. In the first step of the model, XGB, being recognized as high performance ensemble method in the field of data mining, was applied. And the results of XGB were compared with various prediction models such as LOGIT(logistic regression analysis), DT(decision trees), ANN(artificial neural networks), and SVM(support vector machines). In the next step, the threshold is optimized to minimize the total misclassification cost, which is the weighted average of FNE(False Negative Error) and FPE(False Positive Error). To verify the usefulness of the model, the model was applied to a real recidivism prediction dataset. As a result, it was confirmed that the XGB model not only showed better prediction accuracy than other prediction models but also reduced the cost of misclassification most effectively.

In this study, we tried to find ways to minimize the negative effects of workplace bullying by analysing how workplace bullying affects private security guard's job attitude. The results of survey are as follows. First, as the result of analysis how the guard's workplace bullying affects job satisfaction, one of the job attitude, it showed that relational aggression and workplace bullying have a negative effect on their job satisfaction. In other words, job satisfaction decreases as relational aggression and workplace bullying increase. Second, as the result of analysis how the guard's workplace bullying affects their turnover intention, we found that relational aggression and workplace bullying have an effect on turnover intention, especially, relationally workplace bullying has a more effect on their turnover intention than relational aggression, which Is somewhat different from other studies. Study shows that workplace bullying can cause the guard's negative respond and behavior on their job satisfaction, they have to consider transferring another job. Therefore, increasing their job satisfaction and decreasing turnover intention are very important as we are exposed to crimes these days. In this study, we have come with following solutions. First, to increase job satisfaction against workplace bullying, we have to raise the efficiency of their human resources and reduce work ambiguity of actual work burden caused by positive organizational atmosphere and clear responsibility. Second, it is needed to promote personnel exchange between departments and form partnership through regular meetings by targeting common goals to concentrate same interests. At the same time, we have to improve the guard's welfare and working environment by introducing psychological counselling to the victims of bullying.

This study aims at analyzing the global trend of standardization in the field of Industrial Security through ISO/TC 292. It covers broad areas from risk management for industrial property protection and loss prevention through supply chain security, product and document fraud and counterfeiting countermeasures and control and community resilience. It also explores the historical background of the standardization in the security field, how ISO TC 292 came out as a leading group in order to standardize relevant security management systems. TC 292 deals with terminology, general security-related standards and supply chain security management. One of the major findings from this analysis is that security targets and threats are diversified and so organizations like enterprises should have proper flexibility to adapt themselves to new security environment and take appropriate resilience system to cope with the threats and incidents. Also the ISO standardization requires public or private entities to take holistic approaches in security management. Finally, it was found that South Korea has to prepare for this global trend of standardization in this field so that ISO certification market demand and the requirements for transnational trades can be well met.

All measures related to the safety of the casino facilities guarantee safety of facilities that are targets of security guards, protect lives and properties, minimize risks of artificial and natural disaster and crimes. In summary, plan for responding to safety and accidents should be developed not only for the casino facilities but also for the facilities of annexed buildings, and lives and properties of customers and employees. Determine areas in the casino facilities that are prone to accidents and set around-the-clock guard in the areas or maintain surveillance with CCTV and prevent accidents through continuous patrol. These are the most basic and the most important requirements in safety. In addition, casinos which prompt gambling are causing economic and psychological treats to families. To resolve these social issues, casinos have adopted limited entrance system. To support this system, new forms of machine security systems such as video automatic recognition system of fingerprint pattern recognition system should be adopted too. In addition, security guards in casino facilities need to instill themselves with a sense of ownership as well as a strong sense of mission to do the best for customer security and to protect the company assets and employees and manage accidents that could occur without notice. Security guards should do their best to enable manage accidents that could occur without notice. Security guards should do their best to enable tourists who are on the rise due to increase in advanced country-style tourism and leisurely activities to get the utmost satisfaction from the casinos, and as a leader of private security company, establish the foundation for security based on the characteristics of security in Korea.

Since the 1960s, the United States' (U.S.) deinstitutionalization policy has reinstated people with mental illness into communities. Unfortunately, when untreated, some people with psychiatric disorders become homeless, and some commit serious crimes during a psychological crisis. Assisted Outpatient Treatment (AOT), also known as Kendra's Law in New York and Laura's Law in California, provides treatment, services and support to people with mental illness in the community. AOT has repeatedly been found effective and is recognized as an evidence-based practice. The response to the mental health crisis (crisis intervention) in the U.S. has also been successful in preventing worsening mental illness and related criminality and other issues. This paper provides an opportunity to create a platform from which to learn how to successfully apply the AOT and crisis intervention of the U.S. to South Korea within the cultural and societal context when establishing social services for people with mental illness in South Korea's communities.

Recently, the importance of digital forensic has been magnified because of the dramatic increase of cyber crimes and the increasing complexity of the investigation of target systems such as PCs, servers, and database systems. Moreover, some systems have to be investigated with live forensic techniques. However, even though live forensic techniques have been improved, they are still vulnerable to anti-forensic activities when the target systems are remotely accessible by criminals or their accomplices. To solve this problem, we first suggest a layer-based model and the anti-forensic scenarios which can actually be applicable to each layer. Our suggested model, the Anti-Forensic Activites layer-based model, has 5 layers - the physical layer, network layer, OS layer, database application layer and data layer. Each layer has possible anti-forensic scenarios with detailed commands. Second, we propose a fuzzy expert system for effectively detecting anti-forensic activities. Some anti-forensic activities are hardly distinguished from normal activities. So, we use fuzzy logic for handling ambiguous data. We make rule sets with extracted commands and their arguments from pre-defined scenarios and the fuzzy expert system learns the rule sets. With this system, we can detect anti-forensic activities in real time when performing live forensic.

This study examines the degrees of criminal investigators' job satisfaction and organizational commitment and investigates which factors determine the variations in them. In the first step of analysis, independent variables of criminal investigators' job satisfaction consist of work itself, achievement, responsibility, safety, stability, interpersonal relations, recognition, supervision, and opportunity of growth. In the second step, job satisfaction is a mediating variable and organizational commitment is a defendant variable. Organizational commitment is classified into three types - "affective", "continuance" and "normative". According to the structural equation model analysis, responsibility has a great influence on job satisfaction, and job satisfaction affects affective commitment and continuance commitment. This study suggests that job satisfaction should be increased to improve criminal investigators' organizational commitment. And responsibility is necessary for the improvement of job satisfaction. Despite the professional detective system operating in Korea since January 1, 2005, the level of criminal investigators' recognitions of safety, stability and opportunity of growth turn out to be low. Based on these findings, this study presents four ways to reform measures which are listed below. First, to improve a! n economical circumstance of criminal investigators, any expense associated with criminal investigation should be paid by organizations. Second, to improve safety of criminal investigators, it is necessary to develop and supply enough police equipments. Third, criminal investigators' working hours should be shorten. Fourth, to improve criminal investigators' responsibilities, criminal investigators should be allowed to conduct criminal investigation independently from the prosecution.
