Recently, people in cities of developed countries are exposed to unfortified damages of crime and disaster due to urbanization, industrialization and information-oriented era caused by congestion of population in terms of hardware and various social pathology phenomena and frequent and large scale of disaster caused by crime and disorder, which occur in the course of going through nuclear family, a gap between rich and poor and aging society in terms of software. In this regard, demand for security upon individual life and property has been increased but the police that are responsible for the public security does not effectively reduce damage in life and property because their activities are mainly oriented in coping with security accidents more than prevention. Shortage of manpower and budget, retarded equipment, and heavy overwork are the reasons. In order to confront with this kind of situation, we should utilize CCTV system with the purpose of declining possible chances of crime, not for eliminating cause of crime as crime prevention activities to predict danger in advance as a way of prevention and we may expect a role of damage prevention by installing CCTV in places where security accident may possibly happen. In conclusion, there are invasion of privacy, misuse of the system, insufficiency of overall monitoring office management, lack of citizens' understanding and economical allotment of the system installation costs in installation of CCTV system. However. it is necessary to install the CCTV system for effective prevention of crime and prevention activities of security accidents and accurate PR of purposes of installing CCTV to local residents, establishing relevant laws about system misuse, allotment of equipment costs and fees by R&D of the system machinery, cost reduction method of storage, management and replacement, saving costs from co-operative attitude of government, and local autonomous entities and local residents should be involved.

Explosive substances requires much effort for safety management because of the basically risk. The risk of explosives is increasing actually explosives accidents and crimes have been occured repeatedly and explosives used IED(Improvised explosive device) or roadside bomb recently. South Korea's basic legislation on the management of explosives is "guns, swords, explosives control Act" was enacted in 1961 as many amendments have been made. However, the Act has increased complexity gradually because of the technical expertise of explosives such as the development of new techniques. This study examines the historical background of Korea's explosives management and considers enactment amendments and propose measures to improve of explosives management Act.

This study examined the effects of the online community, such as chatting, book-cafe on the neighborhood relationship. Through a case study of 'The Sharp' apartment area, the characters of neighborhood relationship between user and non-user were compared. The factors affecting the community relationships were analyzed by regression analysis. According to the results, the residents using the online community shared their emotions, thoughts and information with their neighbors so that the level of neighborhood relationship was higher. To reprove the neighborhood relationship being cut off the online community should be handled as an important factor in the planning of apartments. This study as a basic research is expected to contribute to policing against crimes and accidents in apartments.

As the Internet technology becomes a major information infrastructure, an emerging problem is the tremendous increase of malicious computer intrusions. The present Intrusion Detection System (IDS) serves a useful purpose for detecting such intrusions, but the current situation requires more active response mechanism other than simple detection. This paper describes a multi-agent based tracing system against the intruders when the system is attacked. The focus of the study lies on the secure communication mechanism for the agent message communication. We have extended parameters on the KQML protocol, and apt)lied the public key encryption approach, The limitation might be the requirements of two-way authentication for every communication through the broker agent. This model ma)r not improve the efficiency, but it provides a concrete secure communication. Also this is one important factor to protect the agent and the tracing server during the tracing process.

By using text mining, we explore the factors responsible for an increase in SUV preference. We collected 32,679 posts related to SUVs from "Bobaedream," the largest online automobile community in South Korea, and applied the LDA topic model. While previous studies have explained the SUV boom as an individual's risk aversion strategy from crime, the result shows that the topic of 'Safety' appears to be an important factor in the SUV discourse in the context of a car accident and high-speed driving situation. To conclude, the consumption of SUVs in Korean society serves as a mean to prevent anxiety and danger to individuals when driving. We insist that decreasing social trust, caused by an increase in inequality, underlies the perception of risk on the road.

Financial institutions keep putting efforts to filling cash into ATMs and branches in order to provide customers with better service. This kind of job usually required an automobile unit to be done, and financial institutions employee perform this task directly or sourcing out to professional security service companies. However, the job has been of ten a target of criminals because it deals with cash. In fact, since 2003, there were several cash truck robberies occurred. This circumstances made the public be aware of the necessity of creative research and the strict management of financial institutions and security companies. However, the existing studies on security service of cash delivery suggest only how to improve the job legally and in operation, and the technological aspect of the improving way has not been studied. Therefore, this study aimed at suggesting an improvement the security service of cash delivery using real-time binary CDMA monitoring for providing better safety service to customers.

The files in computer storages can be deleted due to unexpected failures or accidents. Some malicious users often delete data by himself for anti-forensics. If deleted files are associated with crimes or important documents in business, they should be recovered and the recovery tool is necessary. The recovery methods and tools for some filesystems such as NTFS, FAT, and EXT have been developed actively. However, there has not been any researches for recovering deleted files in XFS filesystem applied to NAS or CCTV. In addition, since the current related tools are based on the traditional signature detection methods, they have low recovery rates. Therefore, this paper suggests the recovery methods for deleted files based on metadata and signature detection in XFS filesystem, and verifies the results by conducting experiment in real environment.

802.11p WAVE is the next-generation wireless communication that can make Ad-hoc network communication possible for Vehicle-to-Vehicle. GBSR protocol, one of the 802.11p WAVE protocols, mainly focuses on improvements in networks that have a tendency to disconnect. However, it does not consider the transmission time and velocity of a packet thus, there is a disadvantage of there being a delay in the transmission velocity, in urgent situations like car accidents, emergency patients transportation and crimes. In this paper, we proposed A-GBSR protocol for transmission of a packet to mobile node which has a high speed through the improved beacon message and Adaptive Neighbor list Management that are considering of the GBSR protocol transmission velocity.

The cases of identification forgery and counterfeiting are increasing under the current identification system, which was established based on social conditions and administrative environments over 20 years ago. This leads to an increase of various criminal acts including illegal loan using fake ID and a number of damages caused out of good intentions that result in interference with the operations of public organizations. In addition, according to the advancement of information society, privacy protection has emerged as an important issue. However, ID card exposes individuals' personal information, such as names, resident registration numbers, photos, addresses and fingerprints, and thus the incidents associated with illegal use of personal information are increasing continuously. Accordingly, this study aimed at examining the issues of ID card forgery/counterfeiting and privacy protection and at proposing a next-generation identification system to supplement such weaknesses. The top priority has been set as prevention of forgery/counterfeiting and privacy protection in order to ensure the most important function of national identification system, which is user identification.
