With the widespread use of digital devices, anonymous communication technologies such as the dark web and deep web are becoming increasingly popular for criminal activity. Because these technologies leave little local data on the device, they are difficult to track using conventional crime investigation techniques. The United States and the United Kingdom have enacted laws and developed systems to address this issue, but South Korea has not yet taken any significant steps. This paper proposes a new blockchain-based crime investigation method that uses physical memory data analysis to track the behavior of anonymous network users. The proposed method minimizes infringement of basic rights by only collecting physical memory data from the device of the suspected user and storing the tracking information on a blockchain, which is tamper-proof and transparent. The paper evaluates the effectiveness of the proposed method using a simulation environment and finds that it can track the behavior of dark website users with a residual rate of 77.2%.

According to dictionary, the meaning of protection is "guard and protect" that means protecting the Protectee's safety in case of sudden attack or various accident and Security means all protecting activity including Protectee and place where he is in or will be as comprehensively meaning of safe. As you see in the definition, Protection and security is the act to protect or will to protect from a security-threat act. A security-threat act can be discussed in the range of the concept of a criminal act in Criminal Law. A security-threat act is based on criminal act in Criminal Law, we are going to review such a security-threat act in a point of view in a sphere of learning in today's remarkable a brain-neuro science and cognitive science based on cognitive psychology, and to use an analysis on such a security-threat act to make a foundation for a establishment of the scientific preventive social security countermeasure. To do so, First of all we are going to review a security-threat act based on criminal act in Criminal Law in a point of protection police logic view. Next, we are going to introduce how cognitive science understand about act of man before we analyse a threat act as one of an act of man in cognitive science point of view. Finally, we are going to discuss the need of cognitive scientific analyse in order to establish the Scientific Preventive Social-security Countermeasure at the same time we are going to analyse a threat act in a cognitive scientific view.

It seems extremely incongruous that genocide, crimes against humanity and war crimes could ever be justified or excused by 'defensive force'- self-defence, defence of others and defence of property. Nonetheless, art 31(1)(c) of the Rome Statute of the International Criminal Court codifies defensive force as a ground for excluding criminal responsibility. This provision was controversial and extremely difficult to negotiate at the Rome Conference of 1998, largely due to the conceptual differences that exist in respect of criminal defences between the various domestic legal systems of the world. This paper analyses the drafting history and wording of art 31(1)(c) in order to clarify the precise scope of defensive force under the Rome Statute. It then seeks to ascertain the applicability of the provision to genocide, crimes against humanity and war crimes, and to thereby explore the nature of these crimes and the intended prosecutorial strategy of the International Criminal Court.

Smoking in elevators is a criminal offense that is included in a misdemeanor. Because of that smoking in elevators can be very critical for our growing children and weak women. In this paper, we would like to extract criminals doing this criminal offense to smoke in elevators. Extraction method detect difference value using modified color-X2-test and it was normalized. Next, we find frames that has occurred scene change in successive frames using the four-step algorithm of scene change detection. Finally, we present the method of smoking image retrieval and extraction in stored large amount of video. In the experiment, we show process and number of scene change detection, and the number of video searched per retrieval time. The extracted smoking video is to submit as evidence for the police or court.

The literal meaning of loitering is "to lingering aimlessly or as if aimless in or about a place". And most criminals show this kind of act before they actually commit crime. Therefore, detecting this kind of loitering can effectively prevent a variety of crime. In this paper, we propose a loitering-detection algorithm using the Raspberry Pi. Proposed algorithm uses an adaptive difference image to detect moving objects and morphology opening operation to enhance the accuracy of detection. The loitering- behavior is being detected by using the center of gravity of the object to see the changes of angle; and pixel movement distance to determine the height of the object. When the loitering-behavior is detected, it outputs the alarm to tell the users by using the Raspberry Pi.

대리운전업은 서비스업으로 세무서에 신고만 하면 사업자 등록을 하고 사업을 할 수 있고, 설사 신고를 하지 않고 영업을 하더라도 규제할 방법이 마땅치 않아 진입장벽이 없는 상태이며 대리운전업에 대한 규제법은 전무한 상태이다. 이들이 법적 관리로부터 방치되어 있는 결과 대리운전행위의 사회적 편익에도 불구하고 요금시비 등 서비스의 질, 생계형 운전미숙자의 진입, 주로 야간에 다수의 낮선 차량을 운전하여야 하고 겸업이 47.3%에 이르러, 과중한 노동으로 인한 피로누적, 주의력 산만, 과속경쟁 등 대리운전의 속성상 교통사고 발생위험, 사고발생시 피해보상책임, 절도나 성폭력행위와 같은 범죄유발 등 여러 가지 문제가 끊이지 않고 있다. 관련업계나 일부 단체에서는 대리운전업 종사자가 15만 명을 넘어섰다고 주장하며 당당한 직업으로 인정해 달라고 요구하고 있고, 근로형태나 조건 등 사업자 내부의 문제도 제기된다. 본고(本稿)에서는 대리운전으로 발생하는 범죄의 현황과 대책을 개괄적으로 조망하고자 한다.

Due to the growth of female movement after 1970s' and the resultant interest in female activity changed the type and degree of female crime and thus led to considerable interest and research. As a result, the relative difference between crime rates of sexes has been reduced, but the crime of male and female has been considerably decreased owing to sex role and concept of self-ego, more generally specking, the result of female movement. As countermeasure for the recently increasing frmale crime, this research presents first, enhancement of social education; second, arrangement of relevant institutions; third, activation of the system of female investigator; fourth, the necessity of victimology approach.

The crimes and the vandalism committed by mental patients such as the burning of Syungremoon and Daegu's subway have become a social insecure factors. In the paper, the criminal status of mental patients is analyzed and the range of probabilities at sea investigated. The countermeasures to these crimes are proposed.

Online game industry and item trade have grown up fast after 2000. And there has been a perspective that online game and item trade are the cause of the crimes, especially cyber crime like hacking, virus. But there was no positive research about the opinion, so this article studies the relations among online game, item trade and crime. The results suggest that online game and item trade maybe a cause of cyber crime and property crime. But online game and item trade don't increase the total number of crime. That means that online game and item trade substitute the way how crime happens. Online game and item trade substitute no-property crime to property crime.

공정거래법은 공법으로 원칙적으로 주무부처인 공정위가 부당한 공동행위의 합의에 대한 추정을 실질적인 경쟁을 제한한다고 판단할 수 있는 정황사실을 통해서 입증해야 할 책임이 있다. 개정된 법조문 내용은 입증 책임을 법집행당국인 공정위가 맡는다는 측면에서는 긍정적으로 판단된다. 기존 독점규제법 제19조 제5항의 법률적 성격을 법률상의 추정규정으로 해석할 경우 부당한 공동행위의 경우 형사소추 대상이 되는 범죄행위로 간주되어 기존 법 제19조 제5항의 법률상의 추정규정이 형사사법체계와 부조화되거나 혹은 실질적 죄형법정주의에 반하는 문제도 금번 법 개정으로 상당히 해소될 것으로 예상된다.
