본 연구의 목적은 알코올 문제의 현황을 파악하고 효과적인 음주교육 방안을 모색하기 위한 것이다. 사회문화적 행위로서의 음주행동의 특징을 파악하고 음주로 인한 위해가 우리에게 미치는 영향을 파악하기 위한 것이다. 음주행동은 한 사람이 속한 사회의 문화와 관습이 허용하는 범위에 따라 그 사회가 공유하는 음주에 대한 태도나 가치의 영향을 받아 학습을 통해 습득하게 된다. 음주는 사망률, 이환율, 유산율, 범죄율 등에 막대한 영향을 끼치고 있으며 이로 인한 사회적 비용과 생명손실은 엄청난 것이다. 매스미디어를 통한 음주교육은 다른법적 제재와 병행될 때 효과적이다. 음주연령이나 세금부과 등을 통해 음주행위를 통제하는 것이 가능하다. 음주교육의 주기능은 법령과 처벌에 대한 두려움(perceived fear)를 높이는 것이다. 음주행위에 관용적인 사회 분위기를 변화시키는 것이 법령이나 처벌보다 더 효과적이다. 과도한 음주행위에 대한 비판적인 사회적 분위기와 같은 비공식적인 사회적인 제재가 음주문제의 예방에 더욱 중요하다. 청소년의 음주행위는 부모와 동료집단과의 관계에 의해 크게 영향을 받기 때문에 부모와 동료집단의 참여하에 객관적인 태도를 통해 자율적인 결정을 할 수 있도록 유도해야 한다. 음주교육에 대해 지식과 경험을 갖춘 교사가 교육을 실시하여야 하며 소그룹 활동을 통해 음주문제에 대한 이해와 바람직한 태도를 습득하게 하고 동료집단의 압력을 거부할 수 있는 능력을 키우는 것이 필요하다. 교사는 편견이 없는 객관적인 태도를 갖추어야 하고 최종적 결정은 지식에 근거하여 청소년이 하도록 하여야 한다. 음주는 가정불화, 좌절감, 실업, 이혼 둥의 부정적 감정과 연관되어 있으며 깊은 인간관계를 통한 상담이 효과적이다. 단주친목과 같은 자발적인 민간단체는 알코올 문제를 가진 사람들이 서로 모여 친목하는 가운데 도움과 치료를 받을 수 있다는 점에서 매우 효과적이다. 이러한 단체의 활용이 더욱 확대되어야 한다. 병원에서의 음주교육은 노조의 참여하에 전문적인 의료인들에 의해 이루어져야 한다. 이전에 알코올중독에서 회복된 사람을 동료교육가(peer educator)로 활용하는 것도 효율적인 교육방법중의 하나이다. 의과대학의 교과과정에 음주교육에 대한 내용을 더욱 확대하여야 한다. 음주교육은 음주라는 행위의 저변에 깔린 문화적 심리적 요인에 대한 깊은 이해를 토대로 계획되고 실시되어야 한다. 음주교육은 지역사회 전체의 참여를 통해 부모, 학생, 정부, 민간단체, 매스미디어의 공동참여를 통한 다각적인 접근이 요구된다.

The demand of violence detection techniques using a video analysis to help prevent crimes is increasing recently. Many researchers have studied vision based behavior recognition but, violent behavior analysis techniques usually focus on violent scenes in television and movie content. Many methods previously published usually used both a color(e.g., skin and blood) and motion information for detecting violent scenes because violences usually involve blood scenes in movies. However, color information (e.g., blood scenes) may not be useful cues for violence detection in surveillance videos, because they are rarely taken in real world situations. In this paper, we propose a method of violent behavior detection in surveillance videos using motion vectors such as flow vector magnitudes and changes in direction except the color information. In order to evaluate the proposed algorithm, we test both USI dataset and various real world surveillance videos from YouTube.

With the increased frequency of crime such as assaults and sexual violence, the reliance on CCTV in arresting criminals has increased as well. However, CCTV, which should be monitored by human labor force at all times, has limits in terms of budget and man-power. Thereby, the interest in intelligent security system is growing nowadays. Expanding the techniques of an objects behavior recognition in previous studies, we propose a system to detect forms of violence between 2~3 objects from images obtained in CCTV. It perceives by detecting the object with the difference operation and the morphology of the background image. The determinant criteria to define violent behaviors are suggested. Moreover, provable decision metric values through measurements of the number of violent condition are derived. As a result of the experiments with the threshold values, showed more than 80% recognition success rate. A future research for abnormal behaviors recognition system in a crowded circumstance remains to be developed.

With the development of IT technology, computer-related crimes are rapidly increasing, and in recent years, the damage to ransomware infections is increasing rapidly at home and abroad. Conventional security solutions are not sufficient to prevent ransomware infections, and to prevent threats such as malware and ransomware that are evolving, a combination of deep learning technologies is needed to detect abnormal behavior and abnormal symptoms. In this paper, a method is proposed to detect user abnormal behavior using CNN-LSTM model and various deep learning models. Among the proposed models, CNN-LSTM model detects user abnormal behavior with 99% accuracy.

Recently, as the demand for Generative Artificial Intelligence (AI) and artificial intelligence has increased, the seriousness of misuse and abuse has emerged. However, intelligent CCTV, which maximizes detection of abnormal behavior, is of great help to prevent crime in the military and police. AI performs learning as taught by humans and then proceeds with self-learning. Since AI makes judgments according to the learned results, it is necessary to clearly understand the characteristics of learning. However, it is often difficult to visually judge strange and abnormal behaviors that are ambiguous even for humans to judge. It is very difficult to learn this with the eyes of artificial intelligence, and the result of learning is very many False Positive, False Negative, and True Negative. In response, this paper presented standards and methods for clarifying the learning of AI's strange and abnormal behaviors, and presented learning measures to maximize the judgment ability of intelligent CCTV's False Positive, False Negative, and True Negative. Through this paper, it is expected that the artificial intelligence engine performance of intelligent CCTV currently in use can be maximized, and the ratio of False Positive and False Negative can be minimized..

Piracy is the enemy of the human race. Pirates commit acts of murder, robbery, plunder or other villainous deeds at sea, cruelly against humanity. The Republic of Korea(ROK), as a big maritime country, is obliged to suppress piracy under international treaties it ratified, including the UN Convention on the Law of the Sea and the two 1988 Conventions against maritime terrorism The Korean government is recently taking a positive attitude towards the regional cooperation which is necessary for the suppression of piracy in the waters of Southeast Asia In spite of the effects of international cooperation to prevent piracy, it is recently on an increasing trend every year. Such circumstances may have a bad effect on the sound development of world economy by means of trade at sea as well as treat to the safety of crews and safe operation of ships. This paper aims to suggest the countermeasures against piracy in terms of criminal law, civil law and international law in order to secure safe operation of vessels at sea.

A larceny means stealing others' properties, as one of crime types most closely connected with common people. Along with fraud, it is the mostly common property crime; in particular, the largest number of people are exposed to a burglary. This study aims to find the schemes to utilize private guards according to the characteristics of burglary. To do so, a questionnaire survey was conducted into an actual condition of official statistics of burglary and into the criminals of burglary, with a view to understanding the behavioral characteristics of burglary and suggesting defense mechanisms to prevent the crime. Burglary is not just a major crime to be dealt with by public guards like the police but also one to be handled increasingly more by private guards. It is why this study intends to identify how to utilize private guards in preventing the crime. Investigations were made into 208 burglars, who were inmates of 10 correctional institutions (prisons or detention houses) across the country. It is found that only about 24% of burglars committed the crime through rational choice, about 60.7% were feared of their arrest at the time of their crime, and a very high percentage (69.9%) of them were assured of their successful crime. Burglaries usually happened at night, mostly in a summer day when everybody goes away from home for vacation. Primarily, the crimes took place in a private house of urban residential quarters. What burglars considered mostly for target selection includes 'profitability,' followed by 'surveillance' and 'risk.' Most (42%) of them committed the crime for the first time ever. Generally, they were not inclined to commit the crime while under the influence of alcohol or drug, which might prevent them from making reasonable decisions. 73.9% of the criminals said that they committed the crime singly without any accomplices.

Nowadays Internet is the greatest and most participating media of prompting expression with 37 million users in Korea. Internet enables collective communications between social members and contributes to form sound public opinions and to develop democracy while it has negative aspect to distribute massively crime by illegal posting which is forbidden by the Criminal Act. Criminal actors who involve to diffuse information on Internet consist of three categories of information provider, user and internet service provider. Illegal posting generated on Internet is originated from IP and the criminal regulation on it is useless and meaningless because of its countless of users and ambiguous boundary with liberty for expression. Accordingly, the only criminal policy means to prevent danger by illegal posting on Internet is to regulate ISP which saves illegal posting and mediates contacts among users. In spite of it, legislation to regulate ISP is unprepared. The prudent legislative review should be done. And it should be accordance with the doctrines of propriety and vagueness of the principle of "nulla poena sine lege".

The penalty clauses of 'Aviation Act' and 'Aviation Safety and Security Act' going into effect now were legislated because the aviation safety is being more influenced by the aviation safety system compared to the ground or maritime transportation and it is possible the aircraft can harm to people and wealth located in the ground as well as threaten the safety of the passengers and crew on board when it is the target of crimes. However, analyzing the current acts, applicable objects and behavioral requirements of some provisions are too general, and they are providing severely high penalties in many clauses without separating applicable objects and behavioral requirements. In addition, there are some critical legislative defects and there is a problem in terms of law-applicable area in the legal system. It is inferred that these legislative problems of the criminal special-law related to the aviation were caused by following reasons; first, aviation security experts or policy-makers than criminal law experts attended more actively in the enactment process, second, the communication among specialist groups were not accomplished well enough.

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.
