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.

Documents in a traditional PDM(Product Data Management) system have been managed in a form of scanned document files or electronic documents developed by specific tools. Though each tool manages documents with its own systematical methods, it has drawbacks in data search, data integration and interchange, etc. For this reason, in this research we propose an efficient document management system for PDM by using the SGML(Standard Generalized Markup Language), one of CALS and ISO standards for document interchanges. Among documents to be managed in PDM, the engineering change notification (ECN) is taken into account. The DTD (Document Type Definition) has been constucted based on the logical analysis of the documents format, In addition, based on the DTD, DB classes have been designed by object-oriented paradigms and a prototype for document input/output and search has been developed using UniSQL ORDBMS (Object-Relational DBMS) and PowerBuilder under the client/server environment.

Hypertext is a web form consisted of HTML(hypertext markup language) which is used in Internet. Hypertext in costume is the product of modem industrial society. Hypertext is not a mechanical technique that enlarges external capacity of human beings. It is rather a motif that extends the internal ability of human beings. It brings about the social innovation by extending the expression realm of costume and providing the various views of recognition. This study regards costume not as an artistic work but as a text which interacts in the open relationship of human body, society and culture and causes dynamic generation of meaning. This study distinguishes Plasticitic Characteristics of Hypertext in Costume with intertextuality, rhizome, interactivity in the structural characteristics of hypertext which is a typical trait of digital culture of openness and variousness. In conclusion, this study clarified plasticitic value of modem costume, which expresses vague isms and the pargidm of multi-typed culture most sensitively and condretley, and expressional forms in relation with the structural characteristics of hypertext.

This paper is to develop and estimate a closed form inflation model using the estimates for real marginal costs in manufacturing industries during the sample period 1975-2010. The production function in manufacturing industry incorporates labor, capital, domestic material, and foreign material, assuming constant returns to scale technology and AR(1) process of technological coefficient. We derive real marginal costs from firm's cost minimization with quarterly data and provide new evidences on the new Keynesian Phillips curve for Korea. The main empirical result is that the closed form coefficients ${\delta}_1$ and ${\delta}^{-1}_2$ in manufacturing for PPI inflation proved to be 0.5086 and 0.8779 respectively, similar to the estimates in the U.S. case. These results also are consistent with the functional relationship between the coefficients in hybrid model and its closed form. Thus the paper suggests that the empirical studies on inflation dynamics need to focus on the manufacturing industry with market power, treating PPI inflation as the dependent variable.

XML documents used for exchanging structured documents between heterogeneous distributed systems are spreading among B2B and the industrial world rapidly. This condition brings an object-oriented visualization tool for modeling XML documents. It is hard to apply for DTD - the rule for declaring document type, which is employed in XML, to various industrial field. Thus, W3C announced Recommendation for XML Schema - the rule for declaring new document type which is adaptable to XML and satisfy to user. Document Type which has high reusability and flexibility can be defined owing to that XML Schema is designed by utilization of Object-Oriented-Modelling technique(UML). This document is proposed the specification and an algorithm for mapping XML Schema to UML.

XML 기술의 발전에 따라 확장성 있는 ebXML(Electronic Business eXtensible Markup Language) 기반의 스키마 사용이 확장되면서 점차 기존 EDI 전자문서나 DTD(Document Type Definition) 구조로 되어 있는 전자문서를 XML 스키마 형태로 변환하거나 새롭게 개발해고 있는 추세이다. 한국전자거래진흥원에서는 XML 전자운세 개발 지침과 함께 XML 라이브러리를 개발하여 제시함으로써 표준 XML 전자문서의 개발을 지원하고 있다. XML 전자문서 개발 지침은 ebXML CCTS 기술규격에서 제시하고 있는 방법론을 준용하고, UN/CEFACT ATG 그룹에서 개발한 XML Naming & Design Rule 규격을 국내에 맞게 수정하여 적용하고 있다. 또한 XML 라이브러리는 전자문서 개발지침에 따라 사전에 정의하고 개발해 놓은 핵심 컴포넌트와 비즈니스 정보 개체들로 구성되어 있다. 하지만 전자문서개발 지침상의 일부 규칙들이 의미상 명확하지 않은 상태에서 개발자의 임의적 선택의 폭을 허용하거나 개체의 명명에 대한 뚜렷한 기준을 제시하지 못함으로써 핵심 컴포넌트와 비즈니스 정보 개체의 검색 및 재사용을 제한하고 라이브러리 유지보수를 어렵게 하고 있는 실정이다. 본 연구에서는 XML 전자문서 개발지침 상의 일부 규칙에 대한 문제점을 분석, 규칙을 구제화함으로써 개발자 중립적인 핵심 컴포넌트와 비즈니스 정보 개체의 개발을 지원하고 라이브러리 관리를 효율적으로 수행할 수 있는 방안을 제시하고자 한다.

While the existing Web focuses on the interface with human users based on HTML, the next generation Web will focus on the interaction among software agents by using XML and XML-based standards and technologies. The inference engine, which will serve as brains of software agents in the next generation Web, should thoroughly understand the Semantic Web, the standard language of the next generation Web. As abasis for the service, the W3C (World Wide Web Consortium) has recommended SWRL (Semantic Web Rule Language) which had been made by compounding OWL (Web Ontology Language) and RuleML (Rule Markup Language). In this research, we develop a backward chaining inference engine SMART-B (SeMantic web Agent Reasoning Tools -Backward chaining inference engine), which uses SWRL and OWL to represent rules and facts respectively. We analyze the requirements for the SWRL-based backward chaining inference and design analgorithm for the backward chaining inference which reflects the traditional backward chaining inference algorithm and the requirements of the next generation Semantic Web. We also implement the backward chaining inference engine and the administrative tools for fact and rule bases into Java components to insure the independence and portability among different platforms under the environment of Ubiquitous Computing.

With rapid growth of internet technology, companies have developed an information system such as the electronic catalog for product data in the E-Business. Due to the heuristic nature of the catalog search for proper tools in the specific process, the intelligent and user friendly methods residing in the search process give a comfortable environment even for the beginners in the field. In this paper, we develop a web based catalog for machining tools especially in Milling process. It has two distinct procedures for the users of the catalog; Search and Analysis. The Search is to select a proper cutter, insert, component combination in the developed relational database based on the cutting process and material. The Analysis is to suggest a recommended optimal cutting conditions based on the machining tools and selected materials. All of these procedures are stored in a server with a program based on the ASP and Java Script where the procedure is initiated by the client using the internet which is accessed through insert. With the success on implementing the above engineering database in the internet, we can provide the foundation for developing PDM with heuristic procedure.

A project planning is one of the most important processes that determines success and failure of the project. A pre-project planning is also essential job for information system implementations at the early stage of project planning, especially for management information system like ERP. However, pre-project planning is very difficult, because lots of factors and their relationships should be considered. Pre-project planning of ERP implementation has been done by project manager's own knowledge and experiences. In this article, we propose a system that help project manager to make a pre-project plan of ERP project with case-based reasoning(CBR) framework. The proposed CBR system saves previous cases of ERP pre-project planning in the case base. Then, the system finds the best similar case with the current pre-project planning problem. Project manager can make a pre-project plan by adjusting the most similar case. From the interview with project managers, we collect some field cases of ERP implementation. We organized these cases by using XML(Extensible Markup Language), which is good for representing hierarchical information. XML gives us some flexibilities to correct and maintain cases. We make a prototype system, PPSS(Project Planning Support System) that help project manager to make a pre-project plan of ERP implementations. The object of the system is to support project manager to make a pre-project plan of ERP. We hope the result of the study can be applied to other information systems. Our research should be extended to cover other stages of project planning.
