코로나19로 인해 비대면 사회가 일상화되고, 가상세계를 구현하는 기반 기술 등이 발전하면서 3차원 가상세계인 '메타버스'에 대한 관심이 급증하였다. 메타버스는 다양한 분야의 활동을 할 수 있다는 점에서 기존의 사이버 공간에서 발생하는 법적 문제들과는 전혀 다른 문제들이 발생할 가능성이 있는데, 현재 메타버스 내에서 이루어지는 다양한 범죄 유형들에 대한 법적 제재나 안전장치가 제대로 마련되어 있지 않다. 이에 본 연구에서는 메타버스의 의의 및 현황을 살펴보고, 주로 문제될 것으로 예상되는 법적 쟁점 등을 검토하고자 한다.

매년 20여명 정도의 경찰이 자살에 이르고 있다. 업무량이 많은 타 공무원에 비해서도 높은 수준이다. 경찰의 자살에는 여러가지 원인이 있지만, 특히 조직의 폐쇄성으로 인해 개인문제로 치부하는 경향이 높다. 경찰의 치안환경은 더욱 안 좋아지고, 위험성에 노출될 확률이 과거에 비해 높아졌으며, 잔혹한 범죄를 마주해야 하는 상황이 많아짐에 따라 우울증이나 업무부담 등으로 인해 자살을 하게되는 경우를 볼 수 있다. 따라서 경찰의 자살을 예방하기 위해서는 심리부검을 도입하는 방안을 법적으로 검도하고, 자살유형들을 분석하여 그에 맞는 자살예방모형 개발하여 자살률을 감소시킬 수 있는 방안을 모색해보고자 한다.

본 논문은 보이스피싱 취약 계층을 위해 통화 내용을 신속하게 처리하여 실시간으로 범죄 여부를 판별하는 VoIP 에 특화된 시스템을 제안하였다. 실제 보이스 피싱 통화 유형을 학습한 탐지 모델을 개발하여 API 로 배포하였다. 또한 보이스피싱 위험도가 일정 수준에 도달할 경우 사용자에게 보이스피싱 가능성을 경고하는 장치를 제작하였다. 본 연구는 보이스피싱을 사전에 탐지함으로써 개인정보의 유출 및 금융 피해를 예방하고 정보 보안을 실천하는 데 기여할 것으로 기대된다.

The emergence of smart phones has brought about a revolution in introducing a computer into the palm of a hand, and this revolution has lead to a smart society that offers comfort and joy in life; however, some side effects including a smart phone syndrome have been identified on a wider and more varied scale compared with any other IT devices of the past. This paper deduced side effect types and key issues according to type focusing on risk factors in accordance with the purpose of the use of smart phones, and diagnosed social effects based on them. In addition, based on the diagnosed results, the study proposed solutions to minimize side effects in order to produce social understanding and sympathy concerning the desirable utilization of smart phones. The proposed solutions should be able to cope with visible and potential side effects systematically by helping people to utilize smart phones, which are a platform of creativity, cooperation, communications, and entertainments, in a desirable way.

Small and medium-sized enterprises play a fundamental role in the foundation of our country's industry and economy, and most technological innovations occur in small and medium-sized enterprises rather than large corporations. Technology development and innovation are the only way for small and medium-sized enterprises to survive in a fiercely competitive environment, so they focus on it, but interest and investment in technology protection tend to be stingy. As a result, industrial technology leakage accidents occur frequently, and it is difficult to meet improvement measures. When a leak occurs, digital evidence is required to prove criminal activity, but problems such as digital evidence being damaged or deleted due to management loopholes often occur. Therefore, through this study, we aim to design a digital evidence-based countermeasure depending on the type of technology leak accident. We will classify the types of technology leak incidents that actually occurred and study ways to secure digital evidence in the security environment of small and medium-sized businesses that operate internal information leak prevention solutions.

When most examining judges deny the request for an arrest warrant, they cite (as a reason) that there is no worry about escape or the destruction of evidence. Consequently, there has been no knowing what characteristics of a crime mainly affect the decision for an arrest warrant and there has been significant dispute about the exact decision criteria used for an arrest warrant. This paper classified the data about the request of arrest warrants for crimes committed in the jurisdiction of the Jinju Public Prosecutors' Office in 2006, 2007 and 2008, into 7 categories according to characteristics of the crimes. For each category we construct a statistical model about the decision on arrest warrants by applying a crosstabulation analysis in order to look for the characteristic of crime that affect the decision for an arrest warrant.

This study analyzed the bicycle traffic patterns and identified the influence factors for each traffic purpose using the household traffic conditions survey for Seoul. The results are summarized as follows. First, as a result of surveying the bicycle traffic ratios according to the administrative dongs, there was a difference of 14.2% by region. Second, various personal characteristic variables, such as age, gender, income, occupation, and housing type, affect the bicycle mode choice, and bicycle passage increases when using facilities in residential areas. Third, among the neighborhood environments, the bicycle traffic for commuting purposes appeared to increase more in the areas of higher land use mix and lower crime rates. In addition, the bicycle road density and the inclination of the area commonly affect bicycle travel for commuting, shopping, exercising, and leisure.

Objectives: Although the characteristics of different aggression subtypes provide important information in establishing treatment and prevention strategies in schizophrenia patients, limited information is available about the characteristics of the aggressive subtype in schizophrenia patients in South Korea. The present study was designed to compare the demographic and psychological characteristics across the impulsive and premeditated aggression subtypes in schizophrenia patients in South Korea who had committed a crime. Methods: We enrolled 116 schizophrenia spectrum disorder patients who were admitted to the National Forensic Psychiatric Hospital. Using the criminal and interview records, the study subjects were divided into 83 impulsive and 33 premeditated aggression groups. The subjects' demographic and psychological characteristics were summarized and compared across aggression subtypes. Results: Compared to the premeditated aggression group, the impulsive aggression group had a higher intelligent quotient and a lower rate of physical and sexual abuse experience. Conclusion: To our knowledge, this is the first study to describe the characteristics of aggression subtypes in schizophrenia patients in South Korea who had committed a crime. Our results suggest that different treatment and prevention strategies should be considered for each aggression subtype.

The 「Act on Special Cases concerning the Punishment of Crimes of Domestic Violence」 still has various problems in the legal system and enforcement process. Contrary to the original intention of the legislation, it is operated very passively in terms of state intervention and punishment of domestic violence actors in actual operation. Even if it is treated as a home protection case, if you look at the details of the protection disposition, there is a problem that the decision on the protection disposition is biased towards a specific type of protection disposition. In order to improve this, the need for cooperation and active intervention between state agencies is required. In addition, it is necessary to establish a legal basis for a request for personal protection by recognizing the status of a victim who reported domestic violence as a crime reporter. In addition, in order to secure the effectiveness of the protective disposition, it is necessary to strengthen sanctions for non-compliance or violations of the protective disposition.

As the importance of technology protection is emphasized day by day, various protection measures are being carried out to protect technology. But attempts to leak technology are continuing. As an alternative to this, stronger punishment is socially required for technology leakage crimes. In response to these social demands, the standard for punishment has been steadily raised. Legislative bills containing additional reinforcement are still pending in the National Assembly. However, in order to substantially enhance the deterrence against crime, it is not enough to strengthen the punishment standards. The effect can only be fully exercised when the certainty of punishment increases. Therefore, this paper focused on seeking ways to increase the certainty of punishment under the current system rather than the reinforcement of the punishment itself. The purpose of this study was to derive the reason why the innocence rate in technology leakage criminal cases is higher than that of general criminal cases by analyzing cases and causes of innocent cases in technology leakage criminal cases. Based on this, I discussed improvement considerations to reduce unfair acquittal cases.
