In this paper, we propose a personal-computer-based wireless data access system, which use DS/SS(Direct Sequence Spread Spectrum) method and the ISM band of 2.44GHz radio frequency. By applying hi-directional transmission between wireless handy terminals and PCs or servers, it can be easily connected with any kinds of database systems such as Oracle, MS-SQL and MS-ACCESS. Therefore, it could be economically adopted as peripheral equipments for ERP or SCM systems.

Risk assessment of a railway system should be periodically conducted managing a large amount of accumulating accident/incident data and scenarios, which generally requires enormous time and efforts. Therefore, special information management system is essential for railway risk assessment, where data needed for decisions on managing the railway safety could be promptly supported. The objective of this study is to develop a railway accident analysis program for risk assessment. The program is application running on the web which links railway accident analysts throughout the railway industry to a central database. Data entered, together with associated code tables. is stored on MS-SQL database. The program uses the concepts of accident, safety events, causes, related factors(vehicle, person, infrastructure, tool/equipment), recommendations to bring together the various elements of railway accidents. The program will be useful in finding hazard conditions, accident scenarios, quantitatively assessing the risk, and providing pertinent risk measures, eventually serving to prevent railway accidents and reduce severities of railway accidents.

XML은 데이터 관리와 표현의 유연성으로 인해 웹의 새로운 개발 도구로 자리를 잡아가고 있으며, 컴퓨터 교육에서는 학습객체라는 많은 웹 컨텐츠들을 통합하는 도구로도 사용되고 있다. 하지만 학습객체를 통합하고 관리하는 온라인 학습 시스템을 구현하기에 앞서, 구현 시스템에서 학습객체를 처리하기 위한 메타데이터를 어떻게 저장하고 추출 및 통합하느냐의 연구가 선행되어져야 한다. 따라서 본 연구에서는 3-tier 방식의 온라인 학습 시스템과 메타데이터가 저장된 데이터베이스 서버를 구현할 때 필요한 메타데이터 추출방법의 하나로 DBMS의 웹서비스를 이용하는 방법을 제안하고자 한다. 제안된 방법의 효율성 측정을 위해 MS SQL Server 2000과 Oracle 9i를 대상으로 30여개의 샘플 메타데이터를 저장하고, 이를 추출하는 응답시간을 측정해 보았다. 이 방법을 사용하기 위해서는 추출된 메타데이터를 DOM/SAX 와 같은 XML 처리 파서가 필요하지만, 측정된 결과 비교적 빠른 응답시간을 보여 데이터베이스에 저장된 메타데이터를 추출하고 통합하는 한 방법으로 충분히 사용할 수 있다는 결과를 얻었다.

최근 토목, 지하수탐사, 환경분야 등에서 각종 지구물리탐사자료의 수요 증가와 이들 자료의 품질관리 및 전산화에 대한 필요성이 대두되고 있다. 따라서, 지구물리 탐사자료의 효율적 관리 및 공유를 위하여 Client/Server(C/S)환경 및 웹(Web)환경 물리탐사자료 관리시스템을 개발하였다. C/S환경의 관리시스템은 MS SQL-Server을 이용하여 관계형 데이터베이스 시스템으로 설계하였고 각종 물리탐사 자료의 규격화, Window용 C/S 인터페이스 프로그램 개발, 검색자료 전송 프로그램 개발 등으로 특징된다. 웹환경에서의 일반 사용자용 데이터베이스 시스템은 물리탐사 이미지자료 표현을 위한 플러그인 모듈개발과, 한국자원연구소 웹사이트 개설 및 홈페이지 작성 등으로 이루어진다.

This thesis describes the effective interfacing methods of PACS Modality based on the system installation andoperating experiences. PACS(Picture Archiving and Communication Systems) is a system for medical image archiving and communication using large storage device and high-speed network. The standard communication protocol of PACS is DICOM(Digital Imaging and Communication in Medicine) based on TCP/IP and point-to-point protocol. However, there are many Non-DICOM Modalities and DICOM Modalities having problems. First, we had interfaced almost modalities. Fuji CR, GE CT, MRI, Angio, Fluoro, Phillips Angio, Shimadzu Fluoro. Ultrasound PACS, with the main PACS in the Seoul S Hospital as large scale hospital. And we manipulated the intelligent image distribution and the CT. MRI Interfaces never experienced beforein the Anyang J Hospital and the Chungju C Hospital as mid or small scale hospital. Technically, we developed both the DICOM Interface and the Non-DICOM Interface. At the last, the DICOM Worklist and the DICOM Print Interface were implemented in the Seoul B Hospital, the Bucheon SJ Hospital and the Seoul K Hospital independently with PACS. The Oracle, Sybase and MS-SQL are used as database, and UNIX, Macintosh, MS Windows as operating systems. And the Visual C++ and UNIX C are the main programming tools. We have used UTP, coaxial and fiber optic cable under 10/100 mbps LAN for networking.

인터넷의 급성장과 더욱 발전하는 On-line환경에 있어서 기업들간의 정보 교환이 실시간으로 이루어지고 있고, 서로 요구하는 정보의 양질이 높아져감에 따라 현 시점에서 데이터베이스의 관리 및 운용이 대우 중요한 요소가 되었다. 본 연구에서는 (주)대한증석과 경희대학교의 공동연구로 만들어진 KT-Guide라는 전자 카달로그를 Web상으로 구축하여, 피삭재의 절삭에 있어서 사용자가 원하는 가공형식, 공구 및 피삭재를 선택하고 적정 데이터의 입력 후에 최적절삭조건을 실시간으로 알아보고자 함을 목적으로 하고 있다. 이것은 사용자가 절삭을 사용함에 있어서 플랫폼에 제한없이 온라인환경에서 보조도구를 사용하게 하며 궁극적으로는 온라인 상으로 CAD/CAM시스템을 사용함을 목적으로 한다. 한편, 이 전의 연구에 있어서도 Web으로의 확장은 있었으나 많은 부분에 있어서 제한적이었다. DB의 관리에 있어서 MS SQL 2000으로의 Upgrade를 선택하였다. 또한, 프로그램 내부적으로는 기존의 대부분이 HTML Tag를 사용한 ASP형태였다면, 본 논문에 있어서 많은 부분이 XML로 전환되었음을 알 수 있다. 절삭조건의 최적화에는 뉴럴 네트워크를 적용하여 연구된 자료를 이용하였으며, Virtual Machining에 있어서 절삭 조건의 검색 및 Query부분은 XML을 이용하였다.

A new algorithm for a coordinative control method is proposed with respect to voltage control and system stabilization of local substations. This is accomplished using control cooperation between a static synchronous compensator (STATCOM) and the existing voltage compensation equipment in the steady state and emergency state of a power system. A real-time system analysis was developed by combining a system analysis program with InTouch, which has primarily been used in factory automation for verification. PSS/E was used for the load flow calculation software, Python for language, Intouch as an HMI program, and MS SQL for the database. To test this system, the system in the vicinity of the Migeum and the Migeum substations was modeled and simulated.

This paper deals with the construction of system for correct location determination of fixed tag. We adapted to construct the above method. Also we adapted the several filtering method. This system was constructed through using of several filtering methods to decrease the location determination error and fingerprint method which is composed of training phase and positioning phase. We constructed this system using Labview 2010 and MS-SQL 2000 as database. This system results in less location determination error than least square method, triangulation positioning method, and other fingerprint methods.

The purpose of this study is to implement web-based quality cost management system to measure the performance of quality improvement activities in the business firms. Developed WQCMS(Web-based Q-Cost Management System) have ability to collect and analyze quality data generated from various different departments in the inside or outside of the enterprise without any limitations, if end-users are able to access wide area network. It provides the capability to integrate quality information from database and to generate various easy analysis reports to management's needs using built-in analysis tool modules with real-time. The proposed system was developed using Microsoft's .Net technology, ASP.NET and MS-SQL Server 2000. By web-enabling Q-cost management system, the effectiveness of the system management and utilization was realized by easiness of information integration and economical efficiency.
