The article considers some issues of criminal law protection of information relations. With the emergence of new types of threats to Ukraine's national security in the field of protection and defense of the state border, the issues of development and strengthening of information protection become especially important. Proper compliance with information legislation also depends on the established responsibility for its violation, which rests on certain provisions of the Criminal Code of Ukraine. It is stated that these norms are placed in different sections and do not have a proper systematization. The article singles out the subjects of information relations in the border area, which are subject to criminal law protection: persons who are not bound by stable relations with the SBGS (who cross the state border of Ukraine, etc.); persons who are members of the SBGS (servicemen and employees); SBGS as a public authority (official and secret information, information about the activities of the agency, its officials, etc.).

This study is trying to analyse the private security prevention role of citizen, For this analyse the public opinion survey on the crime prevention of the private security was carried in Kyungnam area about the crime prevention system and the storage and institution, the role of the crime prevention of private security etc. So that, we have experimented a fact-finding survey about civil consciousness. The result of this fact-finding survey about crime prevention system is on the hand pointed out the circumscription of the police power, and the other hand they have the age-old ceremonies on the dependence about police system. Because the public security order needs the compelling power to maintenance the peace and this power is exercising only by police. They don't have the trust about the role of the private security as the crime prevention institution. But, they consider the private security is just for anyone in particular and special class by their demand. And also, they consider the private security is very expensive to utilize for their security in the everyday life. There for, some people have trust for the private security and if they have a chance for the security, they consider to utilize the private security for their safe life as an security agency. The private security has a powerful experts and so many high-tech equipments for the security. Thus, we have to find a solution to get the best out of it. Because the private security is also a part of crime prevention institution as the police agency.

This study attempts to examine the location and district of elementary schools at Chongro-gu. For the convenience of the analysis, the data are analysed with the methods of GIS network model. For the purpose data was collected from Statistical Yearbook of Education in 1994 and Census of Housing and Population in 1990. Results may be summarized as follows. First of all, spatial pattern of elementary school at Chongro-gu shows outward diffusion because of problems, rising of land value, and out-migration of population in the area. Secondly, for the analysis of locational situation this paper uses the data such as population of 5-9 age, the number of housing, accessibility, and land value. The location of elementary school is ciassified into 4 types; the best area, better area, worse area, the worst area. The best area is Pyongchana-dong, Buam-dong, and Ewha-dong and the worst area is Chongro 1ga-dona, Chonaro 2ga-dong and Sechongno-dong. Thirdly, the alternative plans of school district are presented for the maximum equity and efficience, and security of school attendantes. The former emphasizes the minimization of commuting distance, the later emphasizes the minimization of the an comfortable facilities such as main streets in school district. Present school district which is based upon administrative dong should be changed to roadbased school district.

The purpose of this study is to investigate the sedimentation area and runout distance in the downstream when debris flow occurred on a mountain slope through an experimental performance. Super typhoons and torrential rains caused by climate change cause large-scale debris flow disasters in the downstream areas of mountainous areas, mainly where sediments are deposited and flowed downstream. To analyze the characteristics of the sediment deposited downstream, the disposition area and runout distance were investigated through experiments in the case of a straight channel and channel with berm, respectively. As experimental conditions, changes in sediment volume concentration and channel slope, and channel with or without berm, reduction rates in sedimentation area and runout distance were investigated. In the straight channel, the steeper the channel slope and the lower the sedimentation concentration, the sedimentation area and runout distnace were increased. In a channel with berm, the runout distance and sediment area increased as the slope became steeper and the sediment area decreased.

The purpose of this study is mainly to provide theoretical basis of private security industry by analyzing the perception and flow of private security from the press-released materials according to periodic classification and duties through 'Big Kinds', a website of analyzing news big data. The research method has been changed to structured data to allow an analysis of various scattered unstructured data, and the keywords trend and related words by duties of private security were analyzed in growth period of private security. The perception of private security based on the results of the study was exposed a lot by the media through various crimes, accidents and incidents, and the issues related permanent position. Also, it tended to be perceived as a simple security guard, not recognized as the area of private security, and judging from the high correlation between private security and police, it was recognized not only as a role to assist the police force, but also as a common agent in charge of the public peace. Therefore, it should objectively judge the perception of private security, and through this, it is believed that it should be a foundation for recognizing private security as a main agent responsible for the safety of the nation and maintaining social orders.

As one member of the Korea Society of Systems Engineering (KOSSE) and especially as a member of Sociotechnical Systems session of the KOSSE, I tried to contribute somehow to the activity of KOSSE to help development of better Korea systems. This report is a brief discussion of the need for KOSSE activity in the Cyber Security area especially for the protection of national critical infrastructure systems from cyber terror.

본 논문에서는 GF(2$^{m}$ ) 상에서 효율적인 공간 복잡도를 가진 LFSR(Linear Feedback Shift Register) 구조 기반의 모듈러 곱셈기를 제안한다. 제안된 구조는 기약다항식으로 모든 계수가 1인 속성의 AOP(All One Polynomial)를 이용한다. 제안된 구조는 구조복잡도 면에서 기존의 구조들보다 훨씬 효율적이다. 제안된 곱셈기는 공개키 암호의 기본 구조로 사용될 수 있다.

This paper described two case studies on large scale failure of cutting slope. The kind of rock in both sites predominated limestone and shale respectively. These cutting slopes located in northern area of Gyongbug Province are composed of very complicated and various rock mass. Geological characteristics, causes of failure, proceeding of security diagnose, maintenance method etc. of two sites were carried out to check the cutting slope stability and to provide reasonable maintenance method. This paper may provide the useful data for engineers related with design and construction of large cutting slope.

Most works done so far have concentrated on developing data modeling techniques such as multi-level relation for data protection. These techniques, however, cannot be applied to practical area. This is because they require new queries or new architectures. In this paper, we propose a query processing technique for multi-level databases using horizontal partitioning and views, which does not need any change in database architecture and query language.
