SGML(Standard Generalized Markup Language) is proper to view, modify and create new electronic document as documentation standard to create and interchange the structured document information. Accordingly, a study on efficient storage and management of very large structured SGML document information is need. This paper proposes design of data modeling based on GROVE(Graph Representation Of property ValuEs) defined in HyTime(Hypermedia Time-based Structuring Language) and describes design of SGML document storage management system.

Electronic commerce has already existed for over 20 years. In sectors such as retail and automotive, electronic data interchange(EDI) for application-to-application interaction is being used regularly. For defence and heavy manufacturing, electronic commerce life-cycle management concepts have been developed that aim to integrate information across larger parts of the value chain, from design to maintenance, such as CALS(Computer Assisted Life-cycle Support or Computer Aided Logistics Support). Bolero's mission is to provide guaranteed and secure delivery, in electronic form, of trade documentation, globally, based on a binding legal environment and common procedures. Bolero will also provide a platform for provision of neutral cross-industry services.

네트워크를 기반으로 한 인터넷의 급속한 발전은 개인간의 관계뿐만 아니라, 기업간의 업무 내역에 있어서도 많은 영향을 주었으며, 기존 기업간 문서 교환 시스템의 표준으로 활용되어 오던 독자적인 VAN망을 이용한 전통적 방식의 EDI(Electronic Data Interchange) 역시 많은 변화를 가져 왔다. 전통적 방식의 EDI가 기업 간 거래 수행을 할 수 있도록 '표준 포맷'으로 된 기업 거래 문서를 컴퓨터로 상호 통신한다는 EDI의 기본적인 개념에 충실하며 정확한 데이터 전송 및 보안이 가능한 장점에도 불구하고, 초기 구축비용 과다와 패쇄적인 구조로 인하여 시스템 확장에 어려움이 있으며, 또한 유지 보수 및 운영에도 지속적인 추가 비용이 소요되는 단점을 함께 가지고 있다. 본 논문에서는 위와 같은 전통적 방식의 EDI 문제점을 해결하기 위하여 컨테이너터미널과 선사간의 EDI를 이용한 메시지 송ㆍ수신 업무를 지난 2001년 8월 정부에서 기업간 전자 거래를 위한 데이터 교환 모델로서 권고한 ebXML 프레임워크를 이용하여 ebXML기반 EDI시스템으로 구현하였다.

Recently, lots of EDI-VAN (Electronic Data Interchange-Value Added Network) companies challenge to convert their business systems into Web-based e-business frameworks to avoid high cost and closed structure of EDI system. This research proposes e-Transformation strategies for EDI-VAN companies to adopt Web-based e-business standard frameworks such as ebXML (e-business using XML) and RosettaNet. Four migration strategies for EDI companies are presented, and their properties are described in detail. Transformation procedures of two representative strategies are also provided fur the convenience of medium-sized companies. The result of this work can be used as a practical guideline for EDI companies to develop there own transformation strategy suitable to its scale and capability, while minimizing the impacts on the pre-existing business processes.

Electric systems can be classified into two classes on the basis of the location of its energy source. One system is to be connected with its outside energy source. Obviously, these electric system is limited of its motion range and impossible to operate in the situation without a way to find an energy source nearby. another is to posses the energy source within it. These electric systems are free of motion range limit while their using is limited by the life of source. These limits can be tided over by using passive-type RF communication. RF-ID is a system that Is possible to interchange electricity and data by Radio Frequency to locate and identify various objects including a man.

Electronic Data Interchange (EDI) is an important part of interorganizational electronic commerce due to the strategic impact derived from its use. In order to ensure successful implementation of EDI, EDI controls must first be developed. Because they are implemented in an environmental context, the characteristics of organizational environments have a significant impact on EDI controls. The control strategy for the EDI system - formal, informal, and automated controls - should fit certain organizational environments. A research model has been developed to depict the moderating effects of six environmental variables including industry, organizational, and task characteristics on the relationships between controls and implementation. It is shown empirically that the relationships between EDI controls and implementation are indeed affected by these factors. The results can help management design formal, informal, and automated controls in view of their own environmental contexts.

Recently international trade environment has been rapidly changed according to information age. In particular, international trade has been carried out with various ways under the digital revolution. In this regard, the companies are handling their business with the open network internet and doing their critical marketing activities which are very different from the existed trade customs. However, trade-related information database which is necessary to import and export activities is partly built, and there are many issues to be settled down. In other words, electronic trade opportunity website in the field of overseas marketing and customs clearance with EDI(electronic data interchange) are developed, but the database which companies can make use of their businesses is not fully supported. Therefore the structured database should be developed urgently from the stage of opening business to that of payment. This study closely analyzes the databases under the trade procedure, look into the problems of those database and suggest the solutions of trade information databases. Finally this study provides a sort of trade infrastructure for the development of international trade by internet through the building of trade information.

이기종 간의 문서 교환 표준으로 제안되 SGML은 문서의 구조정보를 표현할 수 있는 장점으로 인해 CALS(Commerce At Light Speed), EC(Electronic Commerce), EDI(Electronic Data Interchange), 전자 도서관(Digital Library) 등 여러 분야에서 사용되고 있다. 이렇게 SGML이 여러 분야에서 사용됨에 따라 많은 SGML 문서 중에서 원하는 문서를 효율적으로 찾아줄 수 있는 검색 시스템의 필요성이 증가하고 있다. 이에 본 연구실에서는 기본적인 구조 검색을 지원하는 SGML 문서 관리시스템을 기개발하였다. 그러나 이 시스템은 구조 검색을 효과적으로 지원하기 못하기 때문에 본 연구에서는 구조 검색의 기능을 정의하고, 이를 지원하는 새로운 구조 질의어를 정의하였다. 또한 이러한 구조 검색을 효과적으로 지원하기 위한 구조 색인을 정의하였다. 그리고 구조 검색 방식으로 세가지 방식을 각각 구현 및 실험하여 그 중에서 성능이 뛰어난 절충식을 이용하여 검색 시스템을 구현하였다.

Commercial vehicle ESC assessment for curvature road was conducted. The previous study of ESC activation condition for losing controllability utilizing the test protocols of double lane change and sine with dwell method was conducted without considering the geometric complexity of roadway design. Since critical rollover accidents were frequently observed in the exit ramp zone, variety of curve, slope and bank have been added for analysis conditions. Detailed feature of the ramp including location, dimension and design characteristics have been analyzed from the typical trumpet type ramp design. Analyzing accident data from 2008, two specific ramps have been selected due to their complexity in design and severity in steering operation.

본 논문은 인터넷상에서 사용이 가능하며 확장성이 뛰어난 XML을 이용하여 B2B (Business to Business) 사이에 사용되는 EDI(Electronic Data Interchange) 문서를 표현함으로써 이기종 시스템과 응용 프로그램간의 원활한 문서 유통을 이룰 수 있는 시스템의 설계 및 구현에 관한 것이다. 이를 위해 기존 EDI 표준인 UN/EDIFACT 메시지 전송 항목에 기반하여 문서형 정의부(Document Type Definition, DTD)를 개발했으며 메시지 수행 지침서(Message Implementation Guide, MIG)를 이용하여 템플리트를 구성하였다. 동적인 XML/EDI 문서를 생성하기 위하여 트랜잭션 처리기 및 생성된 XML 문서의 표현을 위하여 XML 스타일 언어(eXtensible Stylesheet Laguage, XSL)를 자동으로 생성, 변경할 수 있는 XSL 편집기를 개발하였다. 또한 변환 처리기를 두어 기존 EDI 시스템과 원활하게 문서를 교환할 수 있도록 설계 구현하였다.
