최근 컴퓨터 기술의 발전과 함께 Mobile 컴퓨터 환경도 함께 급속히 발전하고 있다. 이로 인해 오프라인 컴퓨팅 및 네트워킹을 이용하던 사용자들이 Mobile 컴퓨팅 환경을 자주 이용하게 되고, Mobile 솔루션에 대한 사용자의 요구도 다양화되고 있는 추세이다. 이 중 Mobile 지도 서비스는 휴대하기 편한 Pocket PC라고도 불리는 PDA(Personal Digital Assistants)는 자신의 현재 위치를 확인할 수 있는 GPS(Global Positioning System)가 급속도로 보급됨으로써 Mobile 환경에서 가장 활용도가 높은 서비스로 부각되고 있다. 가까운 미래의 IT기술은 GPS와 PDA 등을 연계한 e포지션의 폭발적인 이용 증대와 국내 원천기술에 의한 세계적인 사업모델의 탄생이 눈앞에 현실로 다가오고 있다는 점을 감안하면, GPS를 활용한 Mobile 기술력 확보는 국가적 차원에서 대단히 중요하다는 견지를 같이하는 전문가들이 많다. 이러한 시대적 요구 환경 하에서, 본 논문에서는 JAVA VM 기반의 무선위치추적 제어미들웨어와 GIS 프로그램(Vector MAP Viewer)을 구축함으로써 APTS의 효율성에 관한 연구를 제안하고, 앞으로의 향후 개선방향을 제시하고자 한다.

We developed the PERUPS system to aid the on-line performance analysis for the turbine cycle of the YongGwang 3 and 4 nuclear power plants. Procedure of measurement validation is included in the performance calculation to obtain heat balance. Precision of on-line performance calculation is increased via practical modifications of standard calculation algorithms based on the PTC (Performance Test Code). The proposed system also provides useful Web-based aids for performance analysis, including performance data management, a graphic viewer for heat balance and turbine expansion lines, and synthesized reports of performance.

참여와 공유 개방을 모토로 하는 Web 2.0이 GIS 기술과 접목되면서 GIS 분야에서의 새로운 패러다임으로 제시되고 있는 것이 Where2.0이다. Where2.0은 지리정보와 시맨틱웹을 연동하는 새로운 패러다임으로 Google의 Google Map이나 Microsoft의 Virtual Earth에서처럼 '나만의 지도'라는 새로운 비즈니스 및 서비스 모델이 각광을 받고 있다. GIS 시장적 측면에서 보면 Where 2.0 패러다임의 확산은 전문가 중심(Doer)의 GIS에서 일반사용자 중심(Viewer)의 GIS 시장의 확대로 나타나고 있으며, 비즈니스지원시장과 개인생산성 시장이 지속적으로 확대될 것으로 전망되고 있다[IDC2004]. 이에 본 고에서는 최근 이슈로 대두되고 있는 Geospatial Web의 기술적 동향을 살펴보고, 새로운 GIS 패러다임 속에서 보다 효과적인 지리정보 서비스를 제공할 수 있는 맞춤형 지리정보 제공 서비스 개념 및 모델을 제시하도록 한다.

인터넷 이용자 급증으로 정보들은 무한히 생산되고 사방에 산재되어 가고 있다. 이로 인해 정보들을 탐색하는 시간은 계속 증가하고 있다. 특히 공지사항이나 날씨처럼 반복적으로 갱신되는 정보들을 얻기 위해 사람들은 동일한 정보를 주기적으로 검색하고 있으며 이에 따른 불필요한 트래픽 유발 및 검색시간이 낭비되고 있는 실정이다. 본 논문은 동일한 정보를 주기적으로 검색함으로써 야기되는 문제점을 서술하고 이를 해결하기 위해 다수의 웹상에서 각종 정보들만을 추출하여 하나의 웹페이지 내에 배치하는 웹 컴포넌트를 설계 및 구현한다. 이 시스템을 사용한다면 사용자는 단순히 하나의 웹페이지를 클릭함으로써 다수의 웹상에 저장된 정보들을 웹서핑 없이 얻을 수 있기 때문에 정보검색 시간을 크게 단축시킬 수 있다. 이 시스템을 구현하기 위해 크로스 도메인상의 웹문서에서 정보를 추출하고 조작하는 것을 금지하는 웹 표준 정책인 동일출처정책을 우회할 수 있는 방법을 서술하였으며 이 정책을 회피함으로써 파생되는 문제점과 해결방안을 서술하였다. 마지막으로 현존하는 관련 시스템들과 비교하여 우수성을 보인다.

One of the computer application fields which started showing noticeable new growth trends in recent years is the real time communication distributed computing application field. Object-oriented(OO) real time(RT) distributed computing is a form of real-time distributed computing realized with a distributed computer system structured in the form of an object network. In this paper, we describes the application environment as the patient monitor telemedicine system with TMO structure. Vital sign information web viewer systems is also the standard protocol for medical image and transfer. In order to embrace new technologies as telemedicine service, it is important to develope the standard protocol between different systems in the hospital, as well as the communication with external hospital systems. We implemented integration patient monitor telemedicine system between vital sign web viewer systems and hospital information systems.

The remote monitoring system including hemodynamic information and pump status of the implanted animal could be helpful during the in vivo experiment or clinical trial for an artificial heart Implantation. In order to monitor the course of the in vivo experiment continuously and anywhere, web-based remote monitoring system was developed, which can monitor pressures(AoP, LAP, RAP, PAP) and flow information as well as the pump operating conditions. The system consists of data sending, storing viewer part. The data sending part was constructed using component object model and the viewer part was constructed using the Java applet. In addition, the dialog box was introduced to communicate earth other instantly and the alarming function was also introduced when the hemodynamic values were out of the desired ranges. The developed remote monitoring system was applied during the in vivo experiment of the BVAD (Bi-ventricular Assist Device) implantation for 1 month and showed designed work without failure.

An investigation of the tunnel face, as well as related measurement data collected during tunneling, is necessary for rock classification and to determine tunnel stability and the cost efficiency of tunneling. However, systematic management and efficient use of such data have yet to be successfully implemented domestically, and the number of experts in this field in Korea is limited. Thus, measures to develop and implement systematic management and effective use of data and expertise are urgently needed. This study aimed to develop measures to efficiently provide online tunnel design and construction data using a building information model (BIM)-based data visualization approach, based on an integrated 3D tunnel model generation module and a web viewer module. The development technology was verified through ○○ tunnel design and construction. Directions for future study and system improvement are proposed.

The IP cameras have rapidly replaced the analog CCTVs as the cameras have the advantages of not only being able to remotely monitor, but also supplying power through the UTP cable, In this paper, we introduce the protocol architecture of the ONVIF standard which is widely applied to the IP camera and other Internet protocols to support it, and implement the ONVIF Device on a commercial board. Although these functions can be controlled by the Client (PC), several functions such as privacy masks, temperature display of the thermal camera, and ROI (Region of Interest) are implemented through a web viewer on the device. Through the experiment, the functions of ONVIF Profile S and web viewer are verified through SOAP messages exchanged between Device (IP camera) and Client program and streamed images.

As the tools for constructing the cyber world such as virtual theme park on the web, QuickTime VR for 2D panorama Images and VRML for 3D modeling have been used for years. QuickTime VR had some weak points, which were the distortion of images and the difficulties of operating objects vividly and navigating effectively. VRML, though it was able to support various 3D elements to users, was not able to be approached easily by users because of the difficulties for providing viewer. Therefore, in this thesis, we will make it easy for users to approach the contents on the web, offering the concept of X3D components, and profiles and will construct the highly marketable 3D cyber world.
