As computing paradigm of the next generation, Ubiquitous Computing has emerged owing to growing of the Internet and computer networking technologies, and RFID (Radio Frequency Identification) which is the core technology to achieve(realize,actualize) the Ubiquitous Computing environment, is being noticed. MIT's Auto-ID Center has proposed PML(Physical Markup Language) which is based on XML (Extensible Markup Language), is a standard language for describing physical objects, in order to interchange of data between each of these RFID application systems. The PML defines only core parts to describe physical objects, but on the other hand the other parts to be needed in practical application have to be defined with extended definitions separately. In this paper, therefore, the object information data model was designed, which defines the type of the object in order. to process electronic tag information in the RFID application service based on PML Core of Auto-ID Center and is applicable to the distribution service parts.

Medical domain is very applicable for multi-agent system because medical information systems need much knowledge and close relationship with medical staff, In this paper, we describe design and implementation of an intelligent medical multi-agent platform that provides medical images'information services. This platform supports a physical environment that medical agents can be deployed following FIPA(Foundation for Intelligent Physical Agent)\`s agent management reference model. To use a variety of components on Windows, COM(Common Object Model) interfaces and XML(extensible Markup Language) for encoding ACL(Agent Communication Language) are used for multi-agent communications. Since many kinds of diverse and close relationships with medical staff) are essential, a medical staff is conceptualized as an agent and integrated with multi-agent systems. Also it provides an infrastructure applicable to share necessary knowledge between human agents and software agents in order to make intelligent medical information services easier.

This paper describe design and implementation of a medical multi-agent system platform called MAMI (Multi-Agent system for Medical Image), which provides intelligent medical information services. The most important component of MAMI is a medical multi-agent system platform that supports a physical environment that medical agents can be deployed. MAMI follows FIPA (Foundation for Intelligent Physical Agent)\`s agent management reference model. In MAMI, COM(Common Object Model) and XML (eXtensibel Markup Language) for encoding ACL (Agent Communication Language) are used for multi-agent communications. In MAMI, a medical staff is conceptualized as an agent and integrated with multi-agent systems. MAMI agent platform provides an infrastructure applicable to share necessary knowledge between human agents and software agents. So MAMI makes intelligent medical information services easier.

Ubiquitous Computing appeared, and moth researches are gone to apply this in various field. Specially, physical distribution circulation service field is intelligence enemy while alternate existent bar code and induction of RFID(Radio Frequency Identification) technology that permit various service is gone vigorously. In this treatise designed data model and schema to progress research about Core Event Type of PML(Product Markup Language) that is object information expression language that is proposed Auto-Id Lab and EPCglobal Inc. to process information of physical object and EPC-lS(Electronic Product Code Information Services) that is information services component and applies in sea transport physical logistics distribution service field.

XML been using extensively by standard of data exchanging in the Internet is observed by a technology to replace existent document creation language of HTML etc. Biggest characteristic of this XML is that logic information and physical information that express style of document that do that express structural substance of document were detached. Hereupon, W3C advised XSL that oner style function of form similar to HTML for XML's style and data conversion. Also, XSL's conversion function offers function that change XML document to other data format, and can describe style information through conversion of various document format. But, a XML document conversion technology that use XSLT know-how in domestic is unprepared real condition, and necessity about solution that can edit XSLT document efficiently is putting. This paper does XML document so that conversion and output are available in various document format. And offered research of XSLT document editing system that can edit and create XSLT document efficiently under WYSIWYG environment.

Ubiquitous Computing owes Internet and development of computer network and appeared. RFID (Radio frequency Identification) technology is noted by point technology to realize this. However, PML that present in Auto-lD Center is defined point part to describe information of object, and necessary part is to use defining extension separately in actuality application. So that can define object type that can be used for electron tag data processing in RFID application service because do fetters to Auto-lD Center's PML Core in this treatise hereupon and apply in physical distribution circulation service field, designed object information data model.

To realize a ubiquitous logistics management system using the smart object of Electronic Product Code(EPC) enabled RFID tag, the design and management of RFID Information Service is very important. RFID Information Service searches, transfers and responds to the other's PML request, but Physical Markup Language (PML) data management between trading system elements has issues of standardization of PML data description and processing, and problems of data traffic and communication time overload because of the innate distributed characteristics. As a complementary study, this research analyzes the usage patterns and data types of PML. On that analysis we provide a design of the distributed RFID Information Service architecture of PML data management that is using DB middleware. Standalone and Integrated type of RFID IS were proposed.

Conventional indexing sytstems support only full-text indexing method for electronic documents and do not use logical structure of documents in retrieval. Most electronic documents are in different formats depending on various systems. Also, they only indicate physical style of the document without considering any logical structure. Thus, in the effort to standardize the exchange of documents. IS0 developed SGML(Stadard Generalized Markup Language) which contains information about logical structure of the documents. In this paper, to resolve the disadvantages of full-text indexing method and to use standard document format. indexing system for SGML document is designed and implemented. In this system, user can assign indexing domain on elements, thus the logical structure of document is reflected in retrieving information. Various retrieval methods can be implemented by using the structural information of the document. In addition, automatic indexing for SGML Hangul document is supported in this system
