This study tests a model for the effect of low self-control on cyber crime and its mediating process. Intervening variables include smartphone addiction, social learning and opportunity variables. Analyzing a data from college students in Seoul, it is shown that the effect of low self-control has a significant effect on smartphone addiction. Results also show that smartphone addiction has a positive significant effect on differential association with illegal peers, illegal definition, and illegal opportunity, and in turn cybercrime. In addition, it is found that low self-control has also a direct effect on differential association with illegal peers, illegal definitions, and illegal opportunity without mediating by smartphone addiction. As a result, it is reveal that the effect of low self-control on cybercrime is indirect and its effect is mediated by smartphone addiction, differential association with illegal peers, illegal definitions, and illegal opportunity.

In this paper, we propose adaptive convergence security policies and management technologies to improve security assurance in the home networking environment. Many security issues may arise in the home networking environment. Examples of such security issues include the user privacy, the service security, the integrated networking security, the middleware security and the device failure. All these security issues, however, should be fulfilled in phase due to many difficulties including deployment cost and technical complexity. For instance, fundamental security requirements such as authentication, access control and prevention of crime and disaster should be addressed first. Then, supplementary security policies and diverse security management technologies should be fulfilled. In this paper, we classify these requirements into three categories, a service authentication, a user authentication and a device authentication, and propose security policies and management technologies for each requirement. Since the home gateway is responsible for interconnection of many home devices and external network access, a variety of context information could be collected from such devices.

Messenger phishing, communications frauds crime, exploits remote control of smartphones and non-face-to-face financial transactions, causing property damage due to money transfers, as well as account opening and loans in the name of victims. Such financial accidents may be careless of victims, but the current messenger phishing criminal method is intelligent and can be seen as digging into loopholes in the non-face-to-face user verification process. In this paper we analyze how messenger phishing uses loopholes in user identification procedures in non-face-to-face financial transactions. Through experiments, it is suggested to improve the non-face-to-face verification process for safer financial transactions.

There have been many previous studies about an effect of anonymity on self control behavior. However the previous studies are on the aspect of results such as the usefulness, the problems of cyber crime or a lack of trust by anonymity. This study identifies the accurate definition of the objective technical anonymity and subjective social anonymity. And it reveals the relationship among technical anonymity, social anonymity, community tie, and self control as an effect of anonymity. The result of survey shows that technical anonymity affects self control through social anonymity and the relationship between technical and social anonymity is affected by community tie. This study presents how the anonymity affects individual behaviors. So it can be used as a reference to the policy on anonymity of the internet.

This study reviewed the important preceding studies of prevention and treatment of the crimes and therapies on the characteristics of mental illness, trying to investigate and identify more effective ways to prevent, decrease the crimes of the mentally ill and treat them. The main results were as follows. First, relationships between mental illness and crimes have been inconsistently reported, to investigate environmental stresses and triggers of the mentally ill additionally. Second, the term 'mentally illness' was to be defined more specifically, such as severe psychiatric disabled, antisocial personality disorder, intellectual disability, anger·impulse control disorder, and drug abuse. If medication and psychosocial treatments were properly treated to the severe psychiatric disabled, their crime incidence and recidivism will be decrease enough to live with their neighbors in community. But the ways and processes of treating antisocial personality disorder, intellectual disability, anger·impulse control disorder, and drug abuse were very different from it, requiring more intense psychological, medical and biological interventions and social seclusion. The national campaigns and projects for their human rights and community care will be needed to promote the therapeutic effects for them. The limitation and future tasks were discussed.

The preliminary investigative activities by the police officer play a critical role in identifying the cause of death in unnatural death investigations. The failure to secure the crime scene leads to the destruction of significant evidence, which results in the difficulty or impossibility to identify the cause of death. In order to prevent this jeopardizing crucial evidence, and to identify the level of preliminary investigation on the scene, this research is conducted and analyzed with questionnaires of 300 police first responders and 100 detectives. As a result, it was disclosed that there is a possibility for first responders to fail to ensure scene security, scene observation, and canvass interviews. Besides, when medical personnel have no choice but to contaminate the crime scene in order to save lives, it is necessary for them to take photos and to take proper actions before they enter the scene. The importance of scene-control education cannot be emphasized enough in order to prevent media from entering and destroying the evidence. Through research of actual conditions of unnatural death cases which occurred in Kyongbook Province for last five years, the statistics regarding a few different types of death were analyzed as follows. Evidence that homicide, suicide, accidental death, and disaster deaths have increased year by year. Therefore, it is deemed necessary for the government to take multilateral policies to reduce them, and for police to reinforce their investigative skills. Further, the insufficient number of autopsy facilities and forensic pathologists, only 13% of the deceased (1,237 cases) have had an autopsy conducted to identify the cause of death for last five years. The other, 87.3% (8,496 cases) of the deceased, were handled through simple postmortem examination. The significance of this percentage is that there is still the possibility not revealing the cause of unjust deaths. Therefore, it is necessary to furnish police agency with the reasonable amount of funding for autopsies and maintaining enough forensic pathologists.

Recently, the problems in school violence did not stop on the crime between the members at the school and which developed into the invasion crime of the school caused by outsiders. The school is no more the safety zone from the crime. Particularly, in the case of the elementary school, because there are nearly no people who oppose to the outside attacker and can control this, it is the place where it is vulnerable to the invasion crime. The Metropolis of Seoul implements the School Sheriff system within the jurisdiction bureau, in the public elementary school. However, actually the School Sheriff business is being managed, never applying a rule in the Security Industry Law with the main content, that is the Security Industry Law application is excluded. Because the jurisdiction on the contract of Seoul City and operating company are run, the various issues is caused. First, since it is not being considered as a security business, the commercial liability insurance for security company has no chance to applicate when the operation company and the School Sheriff have related damage generation. So the security for the indemnification of loss of the victim is weak. Second, The task of the School Sheriff is ruled just by in the individual contracts. But it is insufficient with this thing. The related duties are required some supplement like a general rule application including the obligation of the guard in the security industry law. Third, the education of the School Sheriff needs to connect with the educational programme in the security industry law. The related professional education specially needed for the prevention of school violence ought to be reserved compensation. Forth, the citizens still demand the strengthening of police patrol for the surroundings of a school in spite of the result of Seoul City's public survey. Therefore, the active relation of cooperation with the police needs to be supported legally and institutionally with the Security Industry Law application. Fifthly, the success of the School Sheriff business can be more guaranteed with the supervision of the legal and institutional device like a the Security Industry Law application or police and all sorts of administrative execution's and etc.

In this paper, we propose IoT based smart CCTV security service to prevent crime in blind spot and prevent unexpected fire or danger. In the proposed method, a RC (Radio Control) car is made using Raspberry pie, and a camera and various modules are installed in an RC car. It was then implemented using Raspbian O / S, Apache Web Server, Shell script, Python, PHP, HTML, CSS, Javascript. The RC car provides a security service that informs the manager of the situation by judging the risk of the scene with modules such as video, voice and temperature. Experimental results show that the transmission time of video and audio information is less than 0.1 second. In addition, real-time status transmission was possible in AVG, emergency, and manual mode. It is expected that the proposed method will be applied to the development of smart city by applying it to unmanned vehicles, drones and the like.

With the increase of social crime rate, the interest on the intelligent security system is also growing. This paper proposes a detection system of monitoring whether abnormal behavior is being carried in the images captured using CCTV. After detection of an object via subtraction from background image and morpholgy, this system extracts an abnormal behavior by each object's feature information and its trajectory. When an object is loitering for a while in CCTV images, this system considers the loitering as an abnormal behavior and sends the alarm signal to the control center to facilitate prevention in advance. Especially, this research aims at detecting a loitoring act among various abnormal behaviors and also extends to the detection whether an incoming object is identical to one of inactive objects out of image.
