본 논문에서는 실시간 대화 행위에서 XML기반 메시지를 이용하여 대화 행위의 체계적 표현을 위한 XML기반 대화 메시지를 설계한다. 설계되는 XML기반 메시지는 대화 문맥의 구분과 문맥 흐름의 표현과 메시지의 다양한 스타일을 지원한다. 또한, 메시지가 XML을 기반으로 작성됨으로써 태그의 확장에 따라 다양한 대화를 효율적으로 표현하는 환경을 지원할 수 있다. 제안하는 XML기반 대화 메시지는 실시간 대화 행위를 위한 대화 메시지의 프로토타입이다. 응용 분양로는 헙업 작업에서 정보의 전달 및 공유, 온라인 게임에서 메시지의 시각적 효과의 지원, 모바일 메신저에서 미디어의 전송 및 표현 방법의 지원, 커뮤니티에서 사회적 행위의 지원 등이다

This paper proposes how to support various media on online conversational activity using XML(extensible Markup Language). The method converts media information into XML based messages and handles alike conventional text based messages. The XML based messages are unified to an XML document, and then a HTML document is generated using the XML and an XSLT documents in a server. A user in each client can play or present media through the hyperlink that is associated media information on the HTML document. The suggested method supports use of various media (text, image, audio, video, documents, etc) and efficient maintenance of font size, color, and style on messages according to extension and modification of XML tags. For application, this paper implemented the system to support media that has client and server architecture on online conversational activity. A user in each client inputs text or media based message using JAVA applet and servlet on the system, and conversational messages on every users' interfaces are automatically updated whenever a user inputs new message. Media on conversational messages are played or presented according to a user's click on hyperlink. Applications for the media presentation are as follows : distance learning, online game, collaboration, etc.

본 논문에서 기존의 항만물류 EDI가 가진 문제점을 해결하기 위한 방안으로 제시된 XML/EDI에 대해 살펴보고, 항만 물류에 XML/EDI를 적용하기 위해 기존의 EDI 메시지를 처리하기 위한 브라우저를 개발한다. XML 문서의 논리적인 구조를 표현하는 방식에 DTD(Document Type Definition)과 XML Schema가 있는데, 여기서는 다양한 데이터 타입를 가지고 있는 XML Schema를 사용해 EDI메시지의 구조를 표현한다. 또한 XML/EDI는 인터넷을 기반으로 하므로 웹을 통해 EDI 메시지를 교환하고자, 메시지 포맷으로 XML을 사용하며, 통신방법은 HTTP를 사용한다.

MTF message is the normalized and standardized format which is used in the time when it tries to transmit data to other systems or exchanges needed information in defense message systems. XML can support variety of search functionality and is estimated to be the best way from the view of efficient presentation and exchange in internet based environment, based on advantage which is independent of hardware and software. US army brought in XML-MTF combining with XML based technology, but we do not contain such a MTF system, and necessity of MTF is increasing for combined operation between ROK and US as a lot of C4I system were transferred to Web based systems. In this paper, we make analysis of fundamental structure, organization of paragraph, witting regulation of MTF message. We present the rule of naming element and fundamental mapping rule for transformation of its XML based on it. Also, we prove that MTF message can be transformed to XML document by trying to transforming sample documents to XML document applying presented mapping rule, creating MTF message based on it and implement program which can automatically transform them to XML-MTF.

Because XML is a W3C standard and has characteristics like platform independent, it has a critical role in electronic commerce. Many electronic commerce systems are already using XML. Business rules and procedures should be standardized for efficient B2B electronic commerce. But a lot of companies have its own XML documents instead of standard documents. In this paper an XML message processor is designed. Clients may request services in XML and server returns response in XML in this system. This XML message processor can be applied easily and used efficiently in electronic commerce systems.

A B2Bi system needs a message storage subsystem that efficiently logs and searches XML messages which have been sent from orreceived by it. XML database systems and XML enabled relational databases systems are not adequate as a message storage system because of their expensiveness and excessiveness in functionality. Storage schemes that split XML messages into database records are also unacceptable because of either low performance or implementation hardness. In this paper, we propose a storage scheme that can be applied to implement a message storage system based on a relational database system. In this scheme, messages are examined only through the index fields that have been registered for each message types. Therefore, the proposed storage scheme cannot support such a powerful search facility like XQL, but it provides high performance message legging and restricted search facility. There are three alternative database schemas to store the index fields. This paper compares the advantages and disadvantages of the three schemas through experimental tests.

본 논문에서는 기존의 항만물류 EDI가 가진 문제점을 해결하기 위한 방안으로 제시된 XML/EDI 에 대해 살펴보고 항만 물류에 XML/EDI를 적용하기 위해 기존의 EDI 메시지를 XML Schema 로 변환하는 기법을 소개한다. XML 문서의 논리적 구조를 표현하는 방법은 크게 DTD(Document Type Definition) 와 XML Schema 의두 가지 방식이 있으며,k XML Schema 는 기존의 DTD 에 비해 다양한 데이터 타입의 지원, namespace 지원, open-ended 데이터 모델의 지원등 여러 장점이 있기 때문에 항만 EDI 메시지를 XML Schema 로 변환하면 DTD 로 변환하는 것에 비해 높은 표현력과 다양한 부가적인 처리를 지원할 수 있다.

Today's computing environment which is getting distributed to communicate with various systems needs dynamic inter-connectivity of the systems. MOM(Message Oriented Middleware) is popularly used for transmitting XML messages among the distributed systems for the inter-connectivity. But, they do not support event-based message routing functionalities with XML transformation for processing effective message routing, which is essential to inter-connectivity, and there is no integrated platform to cope with these requirements. Although event-based message routing and XML transformation have been studied in a wide range of computer science areas, development of message routing systems is considered as a tough job due to the technological difficulties. In order to address these requirements, we proposed a novel system, named RMRS(Rule-based Message Routing System), which supports event-based message routing as well as XML message transformation. To make the proposed system easy to use, we also redesigned ECA(Event- Condition-Action) rule to fit in our system and developed a tool to map source XML structure into target XML structure.

HL7은 텍스트 기반의 의료정보교환 표준이다. HL7메시지는 한 환자가 내원하여 퇴원할 때까지 여러종류의 메시지가 계속적으로 다량 발생하게 되는데, 그 메시지들의 일부 특정 세그먼트들은 반복적으로 생성되어 사용된다는 특징이 있다 그러므로 HL7메시지를 데이타베이스에 저장할 때는 불가피하게 특정 세그먼트들에 많은 중복이 발생하게 된다. 또한 HL7메시지는 프로세스 흐름중심으로 발생되므로, 중복을 제거한 환자중심의 데이터베이스 설계가 필요하다. 본 논문에서는 XML데이타베이스를 사용하여 HL7메시지를 저장하는 방식을 제안한다. 이는 XML DTD가 병원정보를 다루는 여러 의료정보표준들 상호간의 정보교환 및 공유를 위한 스키마로서의 역할을 할 뿐만 아니라, 인터넷을 통해 여러 가지 서비스 제공할 수 있도록 효과적인 저장 및 검색을 지원하기 때문이다. 이질적인 병원정보시스템을 가지고 있는 병원들 간에 의료정보를 교환하고, 환자들의 의료정보를 통합관리 하기 위한 XML데이터베이스를 설계하고 구현하였다.

Recently, as electronic commerce service via the Internet has expanded over the world, the standardization for the e-commerce has been strongly required. Therefore UN/CEFACT and OASIS adopted ebXML standard for the purpose of creating single global electronic marketplace. New e-Business systems should require ebXMl- based messaging system for reliable messaging delivery. In this paper, we have implemented Message Service Handler(MSH) packaging, transporting and managing e-Business messages for supporting ebXML messaging service. The MSH supports various system environments and allows high-level applications running either local or remote hosts with Remote Method Invocation(RMI) interface. In addition, MSH guarantees reliable message delivery on internet since it retransmits message in case of delivery failure and handles duplicated message and applies acknowledgement message for secure message delivery. Nowadays MSH has applied to ebXML registry/repository.
