We constructed the photometric observation system with a small semi-automatic telescope for the systematic observations of eclipse timings of eclipsing binary stars. The system is consisted of a Paramount GT-1100s mount system, a Celestron 14 optical system, and a SBIG ST-8 camera. We developed the OBSTOOL S/W which controls the telescope and the CCD camera using the COM(Component Object Model) supported by the softwares, The Sky and MaximDL. The system performs photometric observations of a variable, comparison and check stars by moving the telescope to the chosen star separately in a similar way such as the method of photoelectric observation. We wrote pert scripts which enable a data handling pipeline for the obtained data to be classified by each of date, object and filter. And thus the images are easily preprocessed using the IRAF S/W package. Eclipse light curves of some eclipsing binary stars observed with this system are presented.

누구나 한번쯤은 CORBA, OLE, COM/DCOM, SOM, DCE와 같은 분산 객체 기술의 핵심이 되는 용어들을 들어 봤을 것이다. 이러한 분산 객체 기술은 현재 우리가 접하고 있는 컴퓨팅 세계에서 가장 중요한 핵심 기술이라 해도 과언이 아니다. 본 고에서는 이들 중에 가장 대중의 관심과 지지를 받고 있는 CORBA의 객체 지향 기술을 살펴보고, 그를 구현한 상용 제품들의 기능을 비교해 봄으로써, 향후 분산 개발 환경을 이용한 시스템 개발에 필요한 사항을 알아보고자 한다.

컴포넌트 시장의 확산으로 소프트웨어 개발 형태가 컴포넌트 기반의 소프트웨어로 새롭게 변형되었다. COM, CORBA, EJB등은 컴포넌트 아키덱쳐들이다. 그 중에서 선의 EJB를 이용하여 만들어진 애플리케이션은 확장성 있고, 트랜잭션을 보장하며 멀티유저 환경에서도 안전하다. UB 설계의 기렬 모델링 언어인 UML을 이용한 EJB 추출방법은 UML 자체가 객체의 식별을 위한 자세한 가이드 라인을 제시하지 않으므로 EJB 추출에 어려움이 있고, 직관적인 경험에 의한 추출방법은 EJB 기반의 프로젝트를 처음으로 개발하고자 하는 개발자에게는 어려움이 있다. 본 논문에서는 정보구조 모델링의 방법[1]을 이용하여 구체적인 객체 추출방법을 제시하며 추출된 객체에서 쉽게 EJB의 빈들로 매핑시킬 수 있다.

This study introduce how distributed object technology can be applied effectively to use in a integrated structural design systems environment with the rapid increasement in the use of network technology. The architecture and management models of the developed systems are described by the CORBA(Com mon Object Request Broke Architecture) distribution standard and objects in Java language. The proposed system can be used for communicating with data between remote designers, regardless of the H/W or S/W platforms they use. Introduction of distributed objects methodologies to a Integrated structural design systems provide advanced levels of integration in structural design environment.

An automatic observation system has been constructed at Chungbuk National University for the purpose of monitoring the bright and long period variable stars effectively. We improved the control part of 40cm telescope of the LX200 and developed n observing software ObsTool II so that the telescope, CCD camera and dome can be controlled in one software. ObsTool II is a COM (Common Object Module) based software, which can be easily reprogrammed in case that a new telescope or CCD camera is installed. Because this system has an additional function in which the telescope can switch the variable, comparison, and check stars respectively as like a photoelectric observation, we can observe the variable star even if the CCD view field does not contain the comparison star with the variable star. In order to check the system stability a W UMa type variable V523 Cas and a magnetic cataclysmic variable TT Ari have been observed with the constructed system and the results have been discussed in context with the possibility of a further application of our automatical observation system.

This paper describe design and implementation of a medical multi-agent system platform called MAMI (Multi-Agent system for Medical Image), which provides intelligent medical information services. The most important component of MAMI is a medical multi-agent system platform that supports a physical environment that medical agents can be deployed. MAMI follows FIPA (Foundation for Intelligent Physical Agent)\`s agent management reference model. In MAMI, COM(Common Object Model) and XML (eXtensibel Markup Language) for encoding ACL (Agent Communication Language) are used for multi-agent communications. In MAMI, a medical staff is conceptualized as an agent and integrated with multi-agent systems. MAMI agent platform provides an infrastructure applicable to share necessary knowledge between human agents and software agents. So MAMI makes intelligent medical information services easier.

Electronic commerce is giving rise to many new and innovative 'gest business practices,' such as telecommuting and the virtual workplace. Telecommuting and the virtual workplace go hand in hand. Today, more then 35 million people in the United States telecommute, and that expected to grow by 20 percent over the next several years. And more then 30 million people used internet shopping mall every years in Korea. Therefore, using the internet and information technology, electronic commerce has the potential to propel a company to 'break out' of existing strategic constraints and radically alter business processes, strengthen customer and supplier ties, and open up new markets. The object of this study is the investigation method for activity solution of electronic commerce of fashion cloth shopping mall in korea. The study has investigated 2 cases about 'halfclub.com' in Korea and 'bluefly.com' in America in the research. Therefore, the study founded the 3problems of electronic commerce at fashion cloth shopping mall in korea and suggested that the activation policies of electronic commerce. The result of suggested that the new electronic commerce style, a lot of contents affects positive effects on the performance of fashion cloth shopping mall in Korea and hope that will be expect new role of electronic commerce to be the herb in fashion cloth shopping mall in korea.

Technology of GIS evolved as a means of assembling and analyzing diverse spatial data. Many systems have been developed, and almost of systems are proprietary. There is a lots of lack of interoperability and reusability between them. This paper describes the development of Open GIS component software. The developing system have an end in view of GIS tool software which is interoperable and reusable. To increase the interoperability and reusability, the system is based on the OGC(Open GIS Consortium)'s Open GIS Simple Features Specification for OLE/COM. The OGC's specification is announced to increasing the full interoperability of various geospatial data and geoprocessing resources. With the Open specification, component based software ensures the reusability. We implement three kinds of component: Geometry component, Spatial Reference System Component, and MapBase Component. The first two components are compatible to the OGC's specification and the third one is designed to GIS tool software for variant GIS applications. The Open GIS component software system is developed on object-oriented computing environment, ATL/COM and Visual C++. As we made application programs using Visual Basic, the advantages of component based Open GIS software was proved.
