In this paper, we develop protocol analyzer that can analyze and monitor LAN(Local Area Network)-based TCP/IP protocol using the OOP(object-oriented programming) in Windows98/NT environment. TCP/IP(Transmission Control Protocol/Internet Protocol) protocol analyzer is consist of interface hardware, protocol analysis software and GUI(Graphic User Interface). It is designed for the real-time analysis using the real-time object. In results of Performance test, TCP/IP Protocol analyzer is showed that it can analyze and monitor without frame error in LAN-based. Also, developed protocol analyser operates better than conventional protocol analyzer in performance. It can be used in maintenance fields of communication and network.

To enhance the educational effect of Multi-Joint Robot have to easily develop motion through the control software. The traditional way of development technique for multi-joint robot is educated with very complicated implementation, but our motion creation tool can be possible to do the creative activity for controling robot movements with ease. This paper mentions to develop the motion creation tool for easily and quickly programming the motion control of multi-joint robot on the educational program. With this tool we easily and exactly provide the education of robot program. In this paper, our suggested tool could not only evade the traditional way of a complicated control program using programming languages but also control easier the robot than the GUI(Graphic User Interface) programming centered on the user's convenience. Additionally, the robot motion's implementation is possible applied with microprocessor experimental equipment educationally to practical use.

A long-term water quality study has been initiated by the Korean Ministry of Environment(MOE) - The G-7 Project--in cooperation with two national research institutes, an University research tn and a consulting firm. This study includes the development of computer software for total water quality management system, so called ISWQM (Integrated System of Water Quality Management). ISWQM includes four major components: a GIS database; two artificial intelligence (AI) based expert systems to estimate pollutant loadings and to provide cost-effective wastewater treatment system for small and medium size urban areas; and computer programs to integrate the database and expert systems. ISWQM is to provide user-friendly Decision Support System (DSS) for water quality planners. A GIS was used to create spatial database which stores all the necessary data to n DSS. GIS was also used to integrate the four components of ISWQM from data creation to decision making through Graphic User Interface (GUI). The results from the first phase of this study showed that GIS would provide an effective tool to build DSS using expert system.

ASN.1/GDMO is the management object used in network management of TMN(Telecommunication Management of Network). However, ASN.1/GDMO is not directly used for managing the network, but translated Into a language with object-oriented paradigm. Therefore we need a development environment for handling ASN.1/GDMO. In this paper we present an integrated development environment(IDE) which consists of an editor and a browser. A user manages ASN.1/GDMO elements with GUI. The IDE is implemented with FLEX and BYACC in UNIX. And Objectivity DB is used as the DB and Tcl/Tk is used for developing GUI. This paper shows how the integrated environment of ASN.1 and GDMO works, and that it enables to manage efficiently the network.

This paper describes the development of a racing game with three-dimensional computer graphics as one of web-based game contents. Client user using web can access and run java applet program with download of Java Bytecode with the independence of hardware system. It consists of graphic user interface module, initial space generation module, event handler module, and thread control module. It uses 2-D linked list data structure for the 3-D graphic objects that are located in three-dimensional space for high-speed object searching and sorting. It enhances the dynamic object moving and viewing in three-dimensional space. We can use the developed racing game to inform game users of information for an advertisement like tourism information, and can apply the proposed 3-D drawing technology to 3-D game graphic engine core.

발전계통 시뮬레이션은 CFO(전산유체역학)을 이용한 시뮬레이션으로서 다차원 미시적인 현상에 대한 시뮬레이션을 뜻한다. 주요 특징으로써 다수의 컴포넌트로 구성된 계통의 다양성으로 보일러, 급수계통, 증기계통, 복수계통 등 다양한 계통들이 존재하고 있다. 따라서 다양한 컴포넌트 모듈을 저장할 수 있는 GUI(Graphic User Interface) 기반의 시뮬레이션 툴이 필요하게 되었다. 현재 발전계통 시뮬레이션 툴의 문제점은 외국의 상용화 툴에 전적으로 의존하고 있으며 이는 곧 시뮬레이터 유지 보수의 어려움을 초래하게 되었다. 본 논문에서는 발전계통 시뮬레이션을 위한 컴포넌트 모듈의 생성, 모듈과 그래픽 라이브러리간의 연결, 유량-압력 알고리즘을 이용한 계통 Solver를 설계하고 멀티스레드를 이용한 복수개의 계통 시뮬레이터 구현 방법을 소개한다.

The reliability and probabilistic generation production cost evaluation of composite power systems are important for power system operation and expansion planning. This paper present a computer program which can evaluate the reliability and probabilistic generation production cost of composite power system using GUI(Graphic User Interface). In this computer program, Monte Carlo simulation methods and CMELDC(CoMposite power system Effective Load Duration Curve) were used.

Power system is becoming more and more complex and large. And power consumption increases rapidly according to the industry development. There is an ample possibility for a fault in proportion to these facts. Therefore power system engineer is requested to abilities, fault analysis and fault prevent. This paper handling result data by Object Oriented Database(OODB) because OODB has advantages abut flexibleness and recycling. Besides this paper presents fault analysis program by Graphic User Interface(GUI) to understand easily program using method.

Scientific literature is the most reliable and comprehensive source of knowledge for scientific and biomedical information. Citation information in the literature is also reliable source for linking between literatures. We proposed CiNet, a graphic user interface based tool that extracts the trend of the research using citation information. We can navigate related literatures and extract keywords from the linked literature using this tool. These extracted keywords will be helpful to researchers who want to survey the information.
