In this research we present a new model, PLCM(Cort-Logistics Chain Management), which can cooperate each other in the port-logistic industry that occupy a heavy rain in the Northeast Asian economy. PLCM(Port-Logistics Chain Management) synthetically manages the logistic chain and information laying stress on the port. Unlike SCM, which hat a vertical relationship between the main groups to cooperate each other, PLCM has a horizontal relationchip between the ports to achieve common purpose and to improve their whole competitive power. In this research we present a concept of PLCM and a specific plan to develop a system for PLCM targetting Pusan, Shanghai, and Tokyo Port which occupy a heavy rain in the Northeast Asian port industry. This system is composed of integrated information system and EDI document exchange system according to the special quality of user's request information. And in order to prove its feasibility and validity, the case study sailing from Shanghai to Busan has been applied to this study.

XML has emerged as the internet standard for information exchange among e-businesses and applications. Therefore, it becomes necessary to store XML documents in database for efficient management. This paper describes the design and implementation of XML documents storage and retrieval system based on object-relational database. The storage method first, decomposes XML document into Element, and then stores according to element types. The system also supports various search methods to retrieve XML documents from database.

New trends such as electronic commerce, virtual organizations, e-business applications, etc. increase the dependence of production management on information software systems and contribute to the needs for global, distributed object systems. This paper presents a component based approach for production management systems under the multi-tier distributed information system architecture using UML(Unified Modeling Language), CORBA(Common Object Request Broker Architecture) and XML(eXtensible Markup Language) technologies, and propose rules for mapping a UML class diagram to a XML DTD (Document Type Definition). And we adapt it to the prototype system implementation. The components are implemented by CORBA and we use XML messages for the information exchange between components.

This paper proposed context based annotation model and annotation ambiguity correction methods. The proposed model provides various annotation types, semantic models, and pen-based free drawing interface. Annotation correction method that is specifically based on the context which includes various textual and structure information between free-form marking and annotation. Also, interface for XML environment using the proposed model and correction methods is proposed and possibilities of application is looked at. The results from the implementation of the proposed method show that the annotated areas included in the free-form marking information are more accurate, achieving more accurate exchange results amongst multiple users in a heterogeneous document environment

지금까지의 정보 시스템들이 기종에 상관없이 프로그램이 실행되고 서로 데이터를 주고받을 수 있는 환경이 성취되어 왔음에도 불구하고, 데이터 자체에 대한 불일치는 범세계적인 지식 컨텐츠공유 뿐만 아니라 전자 상거래 등의 걸림돌이 되어 왔다. 본 논문에서는 XML 문서를 통한 데이터 공유시 효과적인 상호 운용성을 얻기 위해 메타데이터 레지스트리(MDR)를 통한 XML 문서 자동 변환 기법을 제안하고자 한다.

This paper implemented system that run Canonical XML and SOAP messages algorithm. So, can change to more elaborate regular document. Thus, interoperable with other application that takes W3C recommendation. Also, use in several system that physical identify is required when it exchange XML and SOAP messages for web service interoperability. Moreover, Adding the transformation ability between universal encoding scheme and EUC-KR that is internal encoding scheme should be Canonical XML and SOAP messages algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

The Web which supplied static information by web page administrator takes big change, recently, since the web service of new concept called 'WikiWiki' appeared. Wiki system can have gotten very active participation of users because everybody who inspect web page can exchange and add page freely. This paper shows that Wiki engine system implemented by XML and XSLT etc., and explains how to manage the history of document change.

Since XML emerged as a standard for data exchange on the web, it has been widely used for applications like e-Commerce, CRM, and BI. However, it is common that most of business data is stored in relational database systems, and it is expected that business data management would still be centered around the relational database systems. As such, the technique of viewing relational data as XML and processing XML queries against it is required. To meet such a need, in the SQL/XML standard, the functions to publish relational data as XML are provided. In this paper, we propose the techniques of providing an XML view of relational data defined by an SQL/XML statement in DTD(Document Type Definition), and of processing XPath queries against the XML view by translating them into SQL/XML statements, and describe the validation of such techniques through implementation and tests.

인터넷상에서 데이터를 전달하기 위해 XML 기술을 활용하여 분산 환경을 어떻게 더욱 발전된 모습으로 지원해 나갈 수 있을 것인지를 두고 다양한 시도가 이루어지고 있다. 분산 환경에서 XML기술을 활용할 수 있는 분야는 데이터를 표현하여 모든 곳에서 통합화, 표준화하여 모든 사용자들이 접근 가능하도록 하는 기반구조이다. 최근 전자상거래 상(B2B)의 직접적인 거래론 위해서 변환과 문서 전달기능을 수행하는 메시징 시스템이 필요하다. 이러한 메시징 시스템을 XML과 결합하여 사용한다면 신뢰할 수 있고 확장 가능한 구조를 만들 수 있을 것이다. 따라서 본 논문에서는 JMS를 사용하여 B2B상에서 메시지 교환을 자유롭게 할 수 있는 RPC 메시징 모델을 설계한다. 본 메시징 모델을 전자상거래 시스템에 적용하면 B2B 메시지 전송이 용이하게 될 것이다.

최근 국내의 모든 병원에서 PACS(Picture Atchiving and Communication System) 도입에 관한 관심을 보이고 있다. PACS가 구축이 되면 병원 내 모든 진료 과에서 디지털 데이터의 전송으로 정보를 공유할 수 있고, 진료가 자동화 되는 장점이 있다. 하지만, 환자가 다른 병원으로 이송될 경우 과거 진료 내역을 다른 병원으로 함께 전송하여야 되는데, 다른 병원의 시스템과 연계할 방법이 현재로는 존재하지 않는다. HIES 시스템은 의료 데이터 전송의 표준문서로 XML(eXtensible Markup Language)을 제안하고 있다. XML은 문서를 정의하는 메타 마크업(meta-markup) 언어로써 DICOM 프로토콜을 통하여 산출된 의료 데이터를 표현하기에 적당하다. 또한 병원 간 이질 데이터베이스 시스템 통합을 위하여 일관된 스키마 정보를 유지하는 정보 공유 관리자를 설계, 구현하였다.
