Thanks to the developments of IT technologies, such critical infrastructures as fundamental structures of energies, material circulations, monetary circulations, and living necessaries are intertwined as well as mutually dependent. In this respect, the fact that national infrastructures are closely related to IT infrastructures implies not only expected benefits to provide diverse information-based services, but also anticipated costs to bring about new dangers. However, in spite of these threats, traditional researchers have not put enough interests in these indirect danger, which yield the damages in broad areas through paralyzing risk management systems, although they have investigated such direct threats as nuclear accidents, conflagrations, traffic troubles, and gasoline accidents. Considering that the tendency to depend on electricity, so-called electrification, which is caused by automation and informationalization, is intensified in all parts of society, the breakout problem as a factor to inhibit securities in information-oriented society is significant. Thus, the problems of large-scale power blackout should be treated as national crises. Also, preparation systems for large-scale power blackout have to be provided quickly. In this paper, with analyzing various cases of large-scale power blackout and investigation the causes of them, researches on the blackout management systems of Korea are to be present, on the basis of national crisis management states which are comprised of protection (mitigating and preparing), responding, and recovering(rewarding).

With the rapid adaption of the network technologies, there has been in continual troubles with network attacking and computer virus which are getting more automatic and intelligent. To solve them, we survey the existing and currently used security solutions, describe the architecture of traditional network management, and propose the model of a MIB-based security management system which has dedicated management information base on each security solution.

본 논문에서는 사회 안전 환경을 위한 IP-USN 기반의 멀티미디어 응용 개발 프레임워크에서 네스티드 세션 관리를 위한 RARV 구조에 대하여 기술한다. 네스티드 세션이란 하나의 부모 세션 아래에 여러 개의 자식 세션이 존재하는 것을 말한다. 제안한 시스템에서는 새로 생성된 자식 세션은 기본적으로 부모 세션의 설정을 계승하고, 모든 자원에 대하여 동일한 접근 권한을 갖게 하고, 한 참여자는 하나의 네스티드 세션에만 참여하는 것이 허용되는 특징을 갖는다.

Much of the process in Social Science Research can be expedited with use of an automation systems that can lead to research efficiency and dramatic improvement of the research process. This study proposes use of a social science research automation system based on the cloud, which generates questionnaires, supports data collection, and intuitively processes statistical analyses of the data collected. The Cloud-based Social Science Research Automation System is developed with GNU/GPL-based open source software. We also integrate R for statistical computing to enable advanced statistical analyses such as PLS structural equation modeling, mediate effect analysis, compare between groups, and complete general statistics. The Cloud-based Social Science Research Automation system developed in this study is expected to play an important role in improving the social science research process and in performing the social science studies efficiently.

This paper examines the characteristics and determinants of welfare attitudes in Korea. Based on Survey data, this study focuses mainly on how social-economic position variables, welfare status and welfare compliances influence attitudes towards welfare. Welfare attitudes can be classified by five areas as follows: legitimacy of welfare functions, affordability of welfare costs, need-based welfare principles, responsibility of welfare provision and adequacy of welfare spending. There are the major findings. First, attitudes towards welfare is identified state-friendly or pro-welfare attitudes. Second, among the social-economic position variables, welfare status and welfare norms variables, welfare compliance has statistically the most significant effects on welfare attitudes. Third, the level of pro-welfare attitudes is largely determined by welfare norms and images espoused by individuals. These findings suggest that we can not apply cleavages thesis which are developed by studies on the support for welfare state.

본고에서는 미래 스마트 사회(Smart Society) 국가 ICT 인프라 전략으로 스마트 인프라 추진방향을 제시한다. 스마트 인프라는 스마트 인적역량, 법제도, 거버넌스, 네트워크 인프라 등으로 구성되는 디지털 사회간접자본으로서 국가사회 전반의 정보화 하부구조를 이루게 된다. 이에 미래 스마트 사회로의 변화에 따른 스마트 인프라 구성요소별 추진방향을 제안하고, 현재 ICT정책 추진현황에 대한 고찰을 기반으로 스마트 네트워크 중심의 스마트 인프라 추진방향을 제시한다.

정보화 사회가 도래하면서 정보보호의 중요성이 강조되고 있으며, 정보보호 서비스를 제공하기 위한 기반 구조로써 공개키 기반 구조가 구축되어 사용되고 있다. 공개키 기반 구조는 공개키 암호 방식을 사용하는 암호시스템에서 사용자의 공개키를 안전하고 신뢰성 있게 관리하는 수단을 제공한다. 그러나 사용자들의 개인키에 대한 관리 기술은 미비한 실정이다. 최근들어 암호 프로토콜을 이용하여 개인키를 안전하게 관리하기 위한 개인키 관리(PKM; Public Key Management) 프로토콜이 연구되고 있다. 이에 본 논문에서는 공개키 암호 기술에서 사용되는 개인키를 안전하게 관리하고, 키로밍 서비스를 제공할 수 있는 새로운 PKM 프로토콜을 제안하였다.
