This paper presents the development and validation methods of the FUTURE (FUel cycle analysis Tool for nUcleaR Energy) code, which was developed for a dynamic material flow evaluation and economic analysis of the nuclear fuel cycle. This code enables an evaluation of a nuclear material flow and its economy for diverse nuclear fuel cycles based on a predictable scenario. The most notable virtue of this FUTURE code, which was developed using C# and MICROSOFT SQL DBMS, is that a program user can design a nuclear fuel cycle process easily using a standard process on the canvas screen through a drag-and-drop method. From the user's point of view, this code is very easy to use thanks to its high flexibility. In addition, the new code also enables the maintenance of data integrity by constructing a database environment of the results of the nuclear fuel cycle analyses.

Electronic data interchange (EDI) is a new technology of information communication which can make offices paperless. This study develop an EDI system to communicate informations among companies using computer systems. The system consists of five modules-document I/O, translation, system management, communication, and additional modules. The database of EDI documentation standards has been constructed by the table-driven method. The communication module provides three communication modes-RS232C, MODEM, and message handling system (MHS). The system performance has been improved by the method of data compression and data encryption which prevent the communication delay and illegal users. This EDI system can be used as a front-end, back-end, or stand-alone mode.

In this study, a decision support system (DSS) was developed to calculate optimal wastetreatment cost, treatment level and treatment quantity of various pollutants for applying for in rural basin. The DSS includes a gegraphic informatino system (GIS), relational database system (RDBS), water quality models(Loading function , WASP5), watershed pollution load calculation module(SPLC), optimal water quality management plan to satisfy the water quality regulations. The system can be modified by user to trace the optimal condition for decision. The effort was conducted to apply the developed DSS to select the for optimal water quality management plan small rural basin called Kwanri Stream.

A decision support system for determining reservoir capacity, named as KORESIDSS (KOwaco's REservoir SIzing Decision Support System), was developed. The system is composed of three subsystems; a database/information subsystem, a model subsystem, and an output subsystem. This system is operated using MS-Windows with a GUI (Graphic User Interface) system developed using Visual Basic 5.0. As a continuous runoff model, the DAWAST model (DAily WAtershed STreamflow model) developed by Noh(1991) was and its analysis module was developed. This system was applied to a newly-planned dam, the Cheongyan Dam, Which will be located in Cheongyang-Gun, Chungcheongnam-Do and it was proved to be applicable in determining reservoir storage.

Recently, RFID technology is being widely embraced in the supply chain, by manufacturers, retailers, and logistics firms. This study shows the RFID system to provide location based service for commercial vehicle by integrating tracking function of GPS with Mobile service. For this, we configured PC-based terminal for vehicle and developed application consisted of RFID and GPS manager program. In web service module which uses mobile service, commodity information acquired from each vehicle at real-time is added at database and it is analyzed in various aspects to support management decision through the Legacy system.

응용프로그램과 통신처리 프로그램간의 접속에 있어서는 응용 프로그래머가 통신을 고려하지 않고 개발해야 하며 중앙집중식 다자간 통신을 분산식 다자간 통신으로 지원할 수 있는 통신 모듈이 이상적이다. 중앙집중식 통신을 사용시에는 반드시 서버의 역할을 하는 중계시스템을 거쳐야 하지만 분산식 통신을 한다면 중계자론 거치지 않고 통신게임을 원하는 사용자간의 의사에 의해서 게임을 할 수 있다. 본 논문에서는 클라이언트와 서버의 기능을 통합한 단일모듈을 이용해서 분산통신 모듈이 가져야할 편의성, 범용성, 이벤트 동기화, 다중성등에 관하여 논의한다. 그리고 전락 시뮬레이션의 형태에 따른 세가지 유형의 예를 설정한다. 첫째는 웨이브 파일서버의 형태를 갖으면서 정해져 있는 시나리오를 따르는 게임이다. 둘째는 바둑과 같은 형태의 토큰을 통해서 제어권을 행사하는 것이다. 셋째는 토큰을 갖지 않고도 제어권을 행사하는 것이다. 마지막으로 본 논문에서 제안하는 통신모듈을 이용하여서 개발 중에 있는 Death Flower라는 게임을 소개한다.

Development in multimedia technology enhances Computer Supported Cooperative Work(CSCW) such as tole-conferencing and tole-education. These applications are also called groupware applications and usually composed of AM conferencing module and shared working space such as group editors. Through this shared working space users can present, manipulate and save common artifacts interactively. Since users are allowed to operate on common artifacts simultaneously, conflicts between user transactions are bound to happen and can cause unnatural effects on user interfaces. In this paper we reviewed these problems and presented common solutions to concurrency control problems. We also presented Coshed/SAS, a group editor, as an example of groupware applications and related concurrency control problems.

PROSET2000 that is integrated protective management system had developed and used in order to automate the setting process of protective relays in transmission system protection. PROSET2000 have database for relay setting and automated for relay setting program within. This paper proposed PCM current differential relay setting program point of Object Oriented Programming paradigm using Unified Modeling Language about additional relay in PROSET2000. Nevertheless each relay uses same current differential but setting method is different. This paper discribed different thing about setting method of each relay and evaluated more effective and corrective relay setting program using UML.

In this paper we have developed a message transfer protocol, CMP, which improves MSP's message processing capability. The proposed method has taken into account document classification to improve the efficiency of message processing. The difference between the conventional MSP and CMP has been addressed. The CMP's performance has been shown by various experiments including number, alphabet, Korean letter, Chinese letter, music sound and compression file transmission. And security capability of both protocols has been compared based on the specification of FIPS 140-2. The CMP's overall performance is shown to be superior to that of MSP on the processing speed in the performance perspective and on the function of cryptographic module interface and cryptographic key management in the security perspective respectively.
