The growth of computer resource and network speed has increased requests for the use of remotely located computer systems by connecting through computer networks. This phenomenon has hoisted research activities for application service provision that uses server-based remote computing paradigm. The server-based remote computing paradigm has been developed as the ASP (Application Service Provision) model, which provides remote users through application sharing protocol to application programs. Security requirement such as confidentiality, availability, integrity should be satisfied to provide ASP service using centralized computing system. Existing Telnet or FTP service for a remote computing systems have satisfied security requirement by a simple access control to files and/or data. But windows-based centralized computing system is vulnerable to confidentiality, availability, integrity where many users use the same application program installed in the same computer. In other words, the computing system needs detailed security level for each user different from others, such that only authorized user or group of users can run some specific functional commands for the program. In this paper, we propose windows based centralized computing system that sets security policies for each user for the use of instructions of the application programs, and performs access control to the instructions based on the security policies. The system monitors all user messages which are executed through graphical user interface by the users connecting to the system. Ail Instructions, i.e. messages, for the application program are now passed to authorization process that decides if an Instruction is delivered to the application program based on the pre-defined security polices. This system can be used as security clearance for each user for the shared computing resource as well as shared application programs.

This article attempts to examine both the outcome and future task of the art history research on Central Eurasia, better known under the name of "Silk Road". The term Central Eurasia encompasses Xinjiang Uygur, Tibet, Mongolia, former Soviet Republics, the northwest region of India, Iran and Turkey. The article analyzes the 30-year history of the region's art history research and further presents a desirable direction that the study should move towards. Though short in its research period, the ROK's art history study on Central Eurasia has shown eye-catching achievement in several areas such as the northwest region of India and the Xinjiang Uygur, Dunhwang of China. Two factors allowed for this accomplishment. First was the actual improvement of the work environment, where the scholars were finally able to travel to Central Eurasia and explore the historic sites for themselves since 1990. More important was the 'arena of study' for the next-generation scholars made possible by institutions like The Korean Association for Central Asian Studies and the Center for Central Eurasian Studies. Slowly but consistently, the two academic societies induced scholars' attention towards the field and fostered new experts. Circumstances changed, marking 2012 as the starting point. International academic forums held by the government branches surged in number. The intention behind it was to link the ROK with the Silk Road and ultimately to obtain the "Eurasia initiative". As of now, the public has shown heightened interest in the issue. The academia is subsequently riding on this second "wave of interest" following the first wave in the 1980s. However, increased popularity comes with some negative consequences, and this art history research on Central Eurasia is no exception. There are criticisms regarding the objectivity of recent academic forums. Some argue that the aim of the forums are sternly set most of the times, prohibiting the presenters to voice their own perspectives. Still, this heated attention will definitely play its role as a stepping stone for further development. The academia should commit to fostering rising researchers who will systemically and professionally study the field. This is imperative in order for the Korean culture to successfully communicate with the world and take itself to a new level. Without completing this task, the ROK's art history research on Central Eurasia is likely to remain idle.

Archival organizations have been evolving to varying users' needs. The main functional focus of earlier archival organizations has inclined to collection and preservation of data, but their current interests expand to utilization of the data collected. Therefore, today's archival organizations endeavor to procure user-oriented archival information service. This study highlights the programs initiated in last two years by 'Service Innovation Team', a special task force of National Archives of Korea organized in 2005, and presents comparative analysis of those programs with respect to the existing archival systems of National Archives and Records Administration of USA and The National Archives in UK. Additionally, the study, while emphasizing the importance of enlarging and diversifying service programs as well as promoting public awareness over archive resources, introduces the service standards of advanced nations as benchmarks for future archival service policies of pertinent organizations.

The disaster and safety R&D budget has continued to increase since 2008, but the fire safety R&D budget is a small part. Therefore, successful outcomes that could lead to the economic growth of the fire safety industry have not been achieved. This paper suggests a fire safety R&D budget expansion, reinforcement of R&D capacity, and performance growing plan by analyzing the factors that affect the performance of a fire safety R&D project. Empirical analysis was performed through one-way ANOVA and regression analysis using the statistical program, SPSS statistics 21.0. As a result, this study suggests that the continuous expansion of R&D funds and the securing of excellent trained research manpower will be necessary to obtain qualitatively superior patents and papers.

This study aims to analyze operation status of the professional fire investigation education in Korea and derive improvement measures. Study results showed that professional fire investigation educations are conducted mainly by public sectors (Fire Service, Police, Korea Electrical Safety Corp, Korea Gas Safety Corp, etc.) and the educations conducted by National Fire Service Academy are most systematic. In addition, there was no professional fire investigation educations conducted for private sector (fire accident suffers, common peoples, etc.) In order to improve the problems, this study suggests changing the National Fire Service Academy to lifelong education system in coordinance with the scholar's courses of universities, classifying the fire inspector qualification course (executed by National Emergency Management Agency) in five stages, and opening the fire inspector qualification test to the public.

Recently, drones have been used in various field to overcome time and space limitations. However, single drone still has a lot of restriction on transportation wight and travel time. Therefore many studies have been conducted to increase the utilization by swarm of drones. Many things should be additionally considered in order to operate swarming drones securely. Especially the group key management is a challenging research topic in tactical domain due to existence of adversary that has anti-drone skill. In this paper, we proposed an efficient group key management scheme for tactical swarming drone networks where an adversary equipped with anti-drone skills exists. The group key can be updated with a small number of message exchange compared to other convenience schemes. The numerical and simulation results demonstrate that the proposed scheme manages the group key efficiently and securely.

이 연구는 자치경찰제도 도입에 따른 재난대응 실태를 살펴보고 개선방안을 제시하기 위한 목적의 연구로서 연구의 완성을 위하여 경찰의 재난대응 매뉴얼과 관련 통계자료, 법령 등을 종합적으로 검토하여 개선하는 방안을 제시하고자 한다. 자치경찰제도가 도입됨에 따라 기존의 범죄예방 및 기타 치안서비스 제공 시스템에 많은 변화가 발생하였다. 자치경찰제도는 기존의 중앙통제식 경찰제도에서 벗어나 각 지역의 실정에 맞도록 경찰을 운용하는 방식이다. 이러한 자치경찰제도 도입에 따라 많은 기대와 우려가 공존하고 있는 상황에서 자치경찰제도의 취약점이라고 볼 수 있는 대규모 인력이 동원 상황 발생 시 대응에 대하여 여전히 의문을 가지고 있다. 그 중 대형 대난 발생 시 자치경찰의 역할이 대하여 살펴본 결과, 현재 경찰이 대형재난 발생 시 대형재난 현장에서 2차 피해 예방을 위한 현장 통제 및 추가적인 재난 피해 예방, 요구호자 구조 등의 업무를 수행한다. 그러나, 자치경찰의 경우 대규모 재난에 대응하기가 쉽지 않은 탓에 대형재난에 취약할 수 밖에 없기 때문에 이 연구에서는 대형 재난 발생 시 기본적인 경찰의 재난 현장 통제 및 2차 피해 예방활동과 함께 인근 지역 자치경찰과 협동 재난 대응 활동 및 컨트롤 타워 등 제안과 같은 방안을 제안하였다.
