The Grid VO(Virtual Organization) is temporary VO where gather indivisual, authority, or system resource, differ from previous VO concept that controled by internal principal and policy set. It have many problems in case of indivisuals, authorities, or system resources that became member of some Grid VO at same time and combination followed changing condition of system resource for building Grid VO. This paper propose lightweighted Grid VO authentication system based on XML security to solve the authentication of the problems occuring in building Grid VO. In this paper, Grid VO authentication system is including Grid VO authentication module that is intermediate management system in PKI to previous authentication service structure and provide effective authentication service to Grid VO.

Remanufacturing is one alternative to conserve the good environment of our earth and to save the production resources and manufacturing energy. To make active remanufacturing in Korea we have to prepare basic rules to support the collaboration among the original manufacturing, remanufacturing, and repairing companies. Basic rules for active remanufacturing can be established by the analysis of recently environments of remanufacturing procedures and the relationship among the main constituents.

This paper tried to find how the characteristics of purchasing items would have influence on the relational e-procurement. The characteristics of purchasing items include the importance and the complexity of purchasing items. In order to define these characteristics, this paper reviewed various literatures about purchasing strategies. The empirical analysis through the multi-nominal logistic regression shows that the importance of items has influence on relational e-procurement, while the complexity of purchasing process has little influence. And also, the relational e-procurement through EDI as a long term buying relationship is being converted toward the exchange through purchasing sites.

CAE 와 같은 고충실도 대용량 엔지니어링 데이터의 시공간 정밀 분석검증을 위해서는 고해상도 몰입형 가시화 기술과 더불어 이를 직관적이고 효율적으로 제어하기 위한 휴먼 인터페이스 기술이 중요하다. 최근 대중화에 근접한 HMD 기기 및 컨트롤러를 이용한 응용 연구가 발표되고 있고, 이를 통해 엔지니어 위주의 정적 분석환경을 벗어나, 설계/해석/운용 전문가들의 동적 협업분석 환경 제공이 가능한 몰입형 가시화 환경 및 휴먼 인터페이스 기술이 적용되고 있다. 하지만 CAE 해석지원을 위한 대화면 몰입형 가시화 환경에서 사용가능한 직관적 인터페이스기술에 대한 연구는 미진한 상황이다. 본 연구에서는 신체의 자연스러운 움직임으로 가상현실을 탐색하고 데이터 조작을 구현할 수 있는 몰입형 가시화 전용의 휴먼 인터페이스 및 연동기술에 대한 연구과정을 소개한다.

DDoS(Distributed Denial of Service) 공격은 네트워크상에서 다수의 시스템 협업으로 하나의 표적 시스템을 공격하여 서비스의 가용성을 침해하는 공격이다. 이는 점차 지능적인 방법으로 진화하고 있으며 특히 IoT를 대상으로 한 DDoS 공격이 증가하고 있다. 이기종의 기기들이 연결된 IoT는 기존 IT디바이스와 비교하여 제한된 자원을 가지고 있어 IoT 네트워크 특성을 고려한 DDoS 보안 기법이 요구된다. 국제 인터넷 표준화 기구 IETF에서 IoT를 지원하기 위해 제정한 CoAP(Constrained Application Protocol)은 기존 IT 네트워크와 호환성을 가진 응용 계층 프로토콜이다. 본 논문은 CoAP의 DDoS 공격 취약점과 대응 방안을 정리하고 새로운 프로토콜을 추가할 시 고려해야 할 사항을 제시한다.

Purpose The purpose of this study is to investigate the development process and the effectiveness of the EISS (epidemiological investigation support system), which prevents the spread of infectious diseases like a novel corona virus disease, COVID-19. Design/methodology/approach This study identified the existing epidemiological support system for MERS through prior research and studied the case of the development of a newly developed epidemiological support system based on cloud computing infrastructure for COVID-19 through inter-ministerial collaboration in 2020. Findings The outbreak of COVID-19 drove the Korean Government began the development of the EISS with private companies. This system played a significant role in flattening the spread of infection during several waves in which the number of confirmed cases increased rapidly in Korea, However, we need to be careful in handling confirmed patients' private data affecting their privacy.

With the objective of recording the life stories of Paju's long-time residents, the Paju Central Library has been implementing the "Human in Paju" project by forming the Citizen Oral History team since 2017. Building upon the success of this initiative, Paju Central Library became the first library in the country to establish a Records Management team. Subsequently, regulations were enacted, and a committee comprising citizens and officials was formed to ensure the continuous development of the archival project. Moreover, they emphasized public discourse and collaboration at every stage by creating a system to raise awareness of the importance of archiving throughout Paju and support citizens in becoming active participants in the project. This paper aims to present a case study of this exemplary local government library.

This study examined the disclosure and utilization of presidential records by the Presidential Archives in order to expand the use of presidential records. In addition, as issues for the disclosure and expansion of the use of presidential records, the disclosure and provision of the original text, the cancellation and disclosure of designated records, the expansion and reinforcement of research and utilization support, and content were confirmed. In addition, as issues and implications for resolving these three issues, the redesign of the presidential records management work, the revision of the Presidential Records Act, expert collaboration and research, and the preparation of mid- to long-term work plans were suggested.

Cloud manufacturing is a new concept of manufacturing process that works like a single factory with connected multiple factories. The cloud manufacturing system is a kind of large-scale CPS that produces products through the collaboration of distributed manufacturing facilities based on technologies such as cloud computing, IoT, and virtualization. It utilizes diverse and distributed facilities based on centralized information systems, which allows flexible composition user-centric and service-oriented large-scale systems. However, the cloud manufacturing system is composed of a large number of highly heterogeneous subsystems. It has difficulties in interconnection, data exchange, information processing, and system verification for system construction. In this paper, we derive the user requirements of various aspects of the cloud manufacturing system, such as functional, human, trustworthiness, timing, data and composition, based on the CPS Framework, which is the analysis methodology for CPS. Next, by analyzing the user requirements we define the system requirements including scalability, composability, interactivity, dependability, timing, interoperability and intelligence. We map the defined CPS system requirements to the requirements of oneM2M, which is the platform standard for IoT, so that the support of the system requirements at the level of the IoT platform is verified through Mobius, which is the implementation of oneM2M standard. Analyzing the verification result, finally, we propose a large-scale cloud manufacturing platform based on oneM2M that can meet the cloud manufacturing requirements to support the overall features of the Cloud Manufacturing CPS with dependability.
