최근에 모바일 장치 관련 정보 유출과 더불어 유출된 정보를 악용한 범죄가 빈번하게 일어남에 따라 정보호호에 대한 관심과 중요성이 높아지고 있다. 국내 모바일 장치 관련 사용자 수도 해를 거듭할수록 기하급수적으로 증가하고 있는 추세이며, 이에 따른 모바일 장치의 보안에 대한 중요성 역시 대두되고 있다. 그 중에서도 사용자 측의 모바일 잠금 기술인 비밀번호, PIN, 얼굴 인식 등의 기능을 활용하여 사용자 모바일 장치에 대한 암호 보안 기술을 적용하고 있다. 또한 사용자들의 개인정보를 다루는 서비스 이용이 증가함에 따라 모바일 장치 자체의 보안에 대한 안전한 처리 문제, 편리성, 효율성 등을 고려한 문제점이 대두되고 있다. 본 지에서는 사용자 모바일 장치 잠금 관련 동향을 분석하고, 이와 관련된 모바일 장치 잠금 어플리케이션의 한계점에 대해서 살펴본다. 또한 현 모바일 장치 잠금 시스템이 직면하는 보안성과 편의성의 한계점을 보완하기 위한 위치 정보 기반의 모바일 장치 보안 시스템을 제안한다.

CCTV가 범죄 예방 및 수사에 사용되는데, 수사를 위해 저화질 CCTV 영상에서 특정인의 얼굴 인식엔 어려움을 겪어 CCTV 본연의 역할의 희석된다. 따라서 본 논문은 저화질 영상을 고화질로 변환하여 얼굴 인식의 정확성을 높일 수 있는 알고리즘을 연구하는 것을 목적으로 한다. 기존에 연구된 인공지능 기반의 업스케일링 알고리즘을 분석하여 K-FACE 데이터셋에 적절한 모델을 제안한다. 이를 위해 2020년 이전과 이후의 AI 업스케일링 관련 연구를 비교 분석한다. 향후 제시된 모델을 대상으로 동일한 환경내에서 K-FACE 데이터셋을 학습시켜 통일된 기준의 지표 산출이 필요하다.

Due to recent growth in IT industry along with the expansion of smartphone, we came to connect to the Internet wherever and whenever we are. However, this causes negative side effects, though. One of them is a rapid increase of the financial crimes such as the Phishing and the SMishing. There have been many on-going researches about crimes such as Phishing and SMishing to protect users. However, the study about sharing knowledge on SNS to prevent such a crime can be hardly found. Based on social identity theory, we conduct the research about factors on SNS users' intention to share the information security knowledge on SNS. As a result, we found that knowledge provision self-efficacy has a significant impact on self-expression. In addition, it also found out self-expression, awareness about information security and the sense of belonging have a significant impact respectively on the intention to share the information security knowledge on SNS. On the other hand, the altruism didn't have a significant impact to the intention to share information security knowledge on SNS. With this research as a starting point, it seems necessary to expand its range to all types of online community in the future for the generalization of the hypotheses.

The everyday life of police officers requires them to face a number of criminal acts and enter compromising crime scenes. In this case, officers may be compelled to make a personal expression of negative emotions. Negative emotions of members confidence for effective job processing and contributions duties and achievement of the job within the marine police force. Therefore, to control the emotive dissonance of organization members is a great help to the development of the organization. This study focuses on emotional dissonance among marine police officers to verify the impact of this dissonance on job burnout and consider the mediating effect of emotional intelligence. Research results are as follows: First, the relationship between emotional dissonance sub-factors and job burnout among marine police officers was studied. It was found that marine police did not feel emotionally jarred because they consciously tried to abstain from emotional engagement, but this was found to reduce emotional intelligence as related to desired emotions as well. Second, Emotional intelligence of the Marine Police was found on a significant impact on job burnout. Third, the impact of emotions in relation to emotional dissonance that job burnout of marine police intelligence officials confirmed that there is a statistically significant mediating effect. Finally, in a comparison of direct effects versus mediated effects, marine police were seen to be prone to emotional dissonance and experienced job burnout as a direct result of applying greater emotional intelligence.

In the universities of U.S.A., Criminal Justice is the interdisciplinary study of the institutions and policies that constitute the criminal justice system, as well as theories of human behavior and philosophies of justice related to the maintenance of social order, the control of crime, and the achievement of a just society. There are 103 American Universities have Criminal Justice department and they provide about 180 differents courses as a pre-requisition or optional subject in the major. The most 10 courses that those colleges adopted are Introduction to Criminal Justice, Criminal Law, Criminology, Criminal Procedures, Research Methods in Criminal Justice, Criminal Investigation, Juvenile Justice, Terrorism, Ethical Issues in Criminal Justice, Introduction to Psychology or Introduction to Sociology. Also, 10 fields more important in the major if we group together similar courses those are Criminal Justice and Procedures Sequences, Law, Justice and corrections, Theory and Methods Sequences, Homelend Security and Security Operations, Forensics and Cybercrime, Management and Administration, Police, Race and Ethnicity, General Requirements, Other Social Science Fields. The combined degree program leading to Bachelor of Arts Degree in Criminal Justice and Master in Public Administration provides a concentration in criminal justice, management, administration, and leadership. They have big different courses between USA and Korea event though they have similar educative goal and way of approach to the target in the major.

As the number of people using digital devices has increased, the digital forensic, which aims at finding clues for crimes in digital data, has been developed and become more important especially in court. Together with the development of the digital forensic, the anti-forensic which aims at thwarting the digital forensic has also been developed. As an example, with anti-forensic technology the criminal would delete an digital evidence without which the investigator would be hard to find any clue for crimes. In such a case, recovery techniques on deleted or damaged information will be very important in the field of digital forensic. Until now, even though EVTX(event log)-based recovery techniques on deleted files have been presented, but there has been no study to retrieve event log data itself, In this paper, we propose some recovery algorithms on deleted or damaged event log file and show that our recovery algorithms have high success rate through experiments.

Criminology has been understood within a sociological framework until the emergence of neurocriminology, which describes, understands and predicts criminal behaviors from a neurobiological point of view. Not only using biological factors including genes and hormones to understand criminal behaviors, but also using neuroimaging techniques, the field of neurocriminology aims to delve into both structural and functional differences in the brain of individuals with aggression, antisocial personalities, and even the criminals. Various studies have been conducted based on this idea, however, there still are limitations for the knowledge from these studies to be used in the court. In this review article, we provide an overview of the various research in neurocriminology, and provide insight into the future direction and implication of the field.

This study was to explore ex-offender's social readjustment based on the perceptions of correctional professionals and correctional counselors. For the study, 10 correctional professionals were interviewed including university professors majoring in criminology, judges of family court, various correctional workers and 8 correctional counselors responsible for counseling of ex-offender's in the Korea Rehabilitation Agency. The interviews were analyzed using content analysis procedures proposed by Krippendorff(2003). The results were composed of 5 spheres, 15 dimensions, 36 categories, and 77 meaning contents. With regard to social readjustment experiences of ex-offender's, domains such as 'education', 'psychotherapy', 'employment and job search', 'service, culture and leisure', and 'social and national support' were drawn from the analyses. Based on the results of this study, significance and implications were presented.

On the high seas, under international law, a ship is subject to the jurisdiction of the state whose flag she flies. Vessels of any flag are free to navigate the high seas without interference from other states. Thus, there are certain limits of coastal state's exercising law enforcement jurisdiction over a foreign flag vessel on the high seas. However, there are exceptions to exclusive flag state jurisdiction. One of them is the theory of constructive presence. The other is theory of partial execution. Korea Coast Guard's law enforcement authority should be exercised more actively based on those theories supported by the international cases.

The Capital punishment is a sentence which imposes the defendant to be put to death for his crime, thus depriving him/her of life and it's the heaviest punishment of all. It is a very sensitive issue in the sense that it denies a person's life and dignity. It is also an on-going issue which continues to cause political and ethical controversies. Although there is no direct stipulation acknowledging capital punishment in the constitution, there is controversy on the existence of indirect basis. The Art. 12. I. can not be regarded as an indirect provision if it is interpreted to have criminal punishments stipulated by written law. As the supreme Court and the Constitution Court are supporting the capital punishment which seems unconstitutional, legislative examination is inevitable. Considering the fact that the Constitution is neither for nor against the death penalty positively, it is possible to abolish it by enactment of a law and thus, constitutional amendment would not be needed.
