Grid-based PACS can provide an advanced medical information services such as remote image file transfer, collaboration, remote diagnosis, and virtual hospital. In this paper, we have implemented Grid-PACS which guarantees both storage safety and extendability for virtual large scale storage system. The experimental results showed that the virtual storage system provided more efficient and faster data transfer than the conventional PACS. The proposed Grid data management system can be utilized to improve the effectiveness of the PACS data management and transmission between medical institutions.

In this paper, we proposed a mechanism for effective cooperation in sensor network. There are a few mechanism like RBS, TPSN, FPSN for sensor network. However these are supporting synchronization among nodes without global state. Therefore, we proposed SGSM(Simple Global State Management) to maintain global state among sensor nodes. As experimental results, we confirmed loss rate is within 1% as maintaining global state with SGSM mechanism. In this paper, we defined global state in sensor network and introduced SGSM for improving timming accuracy in sensor environment.

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.

최근 건설 산업에서는 비용 절감과 공기 단축 등 건설 프로세스의 새로운 대안으로 BIM(Building Information Modeling)의 효용성이 널리 알려지며 대형건설사와 건축사사무소를 중심으로 BIM 적용을 위한 다양한 시도가 이뤄지고 있다. 이러한 과정은 다양한 분야의 전문가들의 협업으로 이루어지기 때문에 작업자간의 원활한 설계 정보 공유를 위해서는 각기 다른 BIM 소프트웨어에서 만들어 내는 데이터간의 정보호환이 필요하다. 이에 본 논문에서는 빌딩스마트(buildingSMART International, BSI)가 제시한 건축, 엔지니어링, 시공 분야(AEC)의 데이터 교환을 위한 국제 표준인 IFC(Industry Foundation Classes)를 이용하여 이기종 파일 간 호환성 검토 및 문제점 분석을 통해 정보모델개발의 기반자료로 활용하고자 한다.

Teaching and learning research is essential to prepare for the era of the 4th industrial revolution. We must strengthen the creative educational capabilities of prospective teachers by improving the curriculum and teaching-learning model of teacher training colleges. Future education should foster creative thinking based on communication and collaboration. In this study, we improved the future teaching and learning model and applied it to actual classes. In addition, we verified the effectiveness by conducting pre- and post-surveys on the capabilities of future creative teachers. The survey consists of common satisfaction questions and questions about future creative teacher capabilities. As a result of the analysis, we confirmed that the capacity of future creative teachers increased.

The change in information technology demands drastic change in digital library service. This study defines what a social semantic digital library should consist of and proposes a new architecture that incorporates core functions needed in designing a SSDL. The SSDL supports semantic information processing based on metadata and ontology and is an innovation system that allows SSDL users to participate in generating new knowledge by interacting with existing metadata and ontology structures. This study designed a SSDL model that consists of five horizontal and two vertical structures.

This paper proposes a smart glass-based emergency tele-medical direction system. This system is designed for hospital specialists to provide remote medical guidance to on-site coast guards or emergency responders. To identify the requirements necessary for system development, relevant technological trends and case studies were analyzed. Based on this analysis, three system requirements were defined: 1) The system must be able to determine the necessity of patient transport, 2) It should assist in providing emergency medical care during transport to the hospital, and 3) It must be capable of transmitting patient information to medical facilities. A prototype that meets these requirements was developed and its usability was evaluated.

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.

In this paper, we investigate a problem with an e-learning system for e-business environments and introduce the solving method of the problem. To be more accurate, existing Web-hosted and ASP (Application Service Provider)-oriented service model is difficult to cooperate and integrate among the different kinds of systems. So we have produced sharable and reusable learning object, they have extracted a principle from pedagogical designs for units of reuse. We call LIO (Learning Item Object). This modeling makes use of a constructing for XML Web Services. So to speak, units of reuse from pedagogical designs are test tutorial, resource, case example, simulation, problem, test, discovery and discussion and then map introduction, fact, try, quiz, test, link-more, tell-more LIO learning object. These typed LIOs are stored in metadata along with the information for a content location. Each one of LIOs is designed with components and exposed in an interface for XML Web services. These services are module applications, which are used a standard SOAP (Simple Object Access Protocol) and locate any computer over Internet and publish, find and bind to services. This guarantees the interoperation and integration of the different kinds of systems. As a result, the problem of e-learning systems for e-business environments was resolved and then the power of understanding about learning objects based on pedagogical design was increased for learner and instruction designers. And organizations of education hope for particular decreased costs in constructing e-learning systems.

A typical construction project involves participation of various parties including clients, contractors, architects, and engineers for its successful completion, and yet has intrinsic differences of interests among the participants during the project execution period. A construction management (CM) services's role is then to resolve these differences of interests among the participants during the project execution, and lead the projects to its successful completion while representing the clients' demands and interests. The use of building information modeling (BIM) is increasing recently among construction projects, and those CM service companies are experiencing difficulties applying BIM. This is because the use of BIM in construction projects suggests a quite new set of operational paradigm. The purpose of this paper is then to review the recent cases of projects which used BIM; to analyze the these projects' processes; to reengineer the design phase process based on the lessons learned from recent BIM application; and to suggest a modified design phase process model that could improve the use of BIM and related coordination operations.
