최근 의료계에서는 의무기록을 전자문서화 하는 연구가 활발히 진행되고 있다. 더불어 전자의무기록의 표준화에 대한 노력도 병행되고 있으며, XML이 이에 대한 대안 중 하나로 제시되고 있다. 이에 따라 기존 병원 정보시스템에 구축된 의료정보를 XML로 변환하는 방법에 대한 연구가 요구된다. 본 논문에서는 간략화한 의무기록을 XML로 표현하는데 필요한 DTD를 제안하며, Java 프로그래밍 언어를 이용하여 기존 병원의 Legacy Database에 기록된 의무기록 자료를 XML 문서로 변환하고, 전자의무기록 XML 문서를 병원정보시스템에서 활용할 수 있도록 Database에 기록하는 Converter를 구현하였다.

The existing query processing technique for CXQuery, which is able to query regardless of knowledge about XML document structures, is difficult to manage because of table join for query processing and results return, mapping XML documents into relational tables, and so on. In this paper we have developed a converter capable of converting CXQuery to XQuery in order to make use of the query processing techniques for XQuery progressing standardization. The converting speed of the converter takes a trifling time as much as negligible quantities in comparison with the total query processing time. This is also able to query directly XML documents regardless of relational databases, and users can query without knowledge about XML document structures.

The exchange of model design data among heterogeneous CAD systems is very difficult because each CAD system has different data structures suitable for its own functions. STEP represents product information in a common computer-interpretable form that is required to remain complete and consistent when the product information is needed to be exchanged among different computer systems. However, STEP has complex architecture to represent point, line, curve and vectors of element. Moreover it can't represent geometry data of feature based models. In this study, a structure of XML document that represents geometry data of feature based models as neutral format has been developed. To use the developed XML document, a converter also has been developed to exchange modules so that it can exchange feature based data models among heterogeneous CAD systems. Developed XML document and Converter have been applied to commercial CAD systems.

The exchange of model design date among heterogeneous CAD systems is a difficult task because each system has different data structures suitable for its own functions. STEP has been able to represent product information as a common computer-interpretable form that is required to remain complete and consistent when the product informant is needed to be exchanged among different computer system. However, STEP has difficult architecture in is representing point, line, curve and vectors of element, more over it can't represent geometry data of feature based models. In this study, a structure of XML document that represents geometry data of feature based models as neutral format has been developed. To use the developed XML document, a Converter has also been developed to exchange modules so that it can exchange feature based data models among heterogeneous CAD systems. Aa for evaluation of the developed XML document and Converter, Solidworks and SolidEdge are selected.

XML is normalized text form that is designed to transmit structured document in web as that propose in W3C (World Wide Web Consortium) in 1996. Function that this can overcome HTML's limit that use in existing in Internet and user define new tag to HTML by way to solve SGML's complexity added. There is many efforts to use storing this XML document in RDBMS but to relation style DB because XML document is tree structure structurally data SQL and perfect disaster caused by things that is language to ask a question accomplish XQuery that so it is W3C's XML standard query appear. After store XML informations including space information to RDBMS in this paper, Spatial XQuery through converter that is Sqatial XQuery2SQL through Spatial operator, Spatial function SQL of by Sqatial XQuery2SQL conversion algorithm that draw information in RDBMS after change embody wish to.

It is possible to access web contents by mobile terminals and telephones due to the evolution of voice and VoiceXML technologies. Nevertheless, because these days most of all the web contents are constructed by HTML, it is impossible to access them by using the new technology. Therefore, to access the contents through voices requires the conversion of the web document from HTML to VoiceXML, but its manual conversion process should be involved additional time and expenditure. In this paper, we design and implement HTMLtoVoiceXML converter, suggest a system structure of it and propose a practical identification algorithm of meaningful fragmented group of contents to solve the problem. To test the performance and validity of the converter, we apply it to more than 400 web pages in Korean web sites, it works well except for web pages which involve invalid HTML codes.

HTML that is language that web technology is center expression these day that use of internet and quantity of information by fast development increase rapidly brought limit to use information of web and XML that express meaning or corelation of data itself in W3C by standard for free document transmission and exchange in World Wide Web by the alternative as long as is deviation appeared. There is many efforts to use storing this XML document in RDBMS but to relation style DB because XML document is tree structure structurally data SQL and perfect disaster caused by things that is language to ask a question accomplish. In this paper XML document XML informations that is stored to RDBMS via Parsing and DOM tree process SQL quality through converter called XQuery2SQL of by change and embody XQuery2SQL conversion algorithm that draw information in RDBMS.

Web documents specified with HTML and CSS is displayed with high quality on the web browser. However, basically, any printed pages don't have the same quality of softcopy. The reason is HTML and CSS is not suit for printing. The XSL-FO(XSL-Formatting Object) is Formatting Language for imaging of web document and The PostScript is one of the most famous PDL(Page Description Language). To get high-quality pages, we propose the design of converter which translate XML-FO into PostScript format. Using the designed converter, we can get hardcopies with high quality.

To access massive and various HTML documents that are in the web using wireless Internet equipments, another WML document that is equal to the HTML document must be written. In the case Web documents written by HTML are massive, the construction of a WML site with the same information needs much cost of space and time. This paper designs and implements the HTML-XML converter that alleviates such a problem. The HTML-XML converter translates the Web document written by HTML to the WML document for portable wireless equipments. The HTML-XML converter has advantages that it reconstructs WML document dynamically according to portable wireless equipments and processes various image formats such as GIF, JPG, BMP, and so on. The HTML-WML converter can be used as not only a utility of the WML editor but also a real time converter on wireless internet.

At present, the electronic document is being processed in WYSWYG mode. For this, a document is structured by the logical structure and the physical structure, and is presented by the markup language. After XML is announced, an application scope of the electronic document is extended from interchanging to searching. However, in point of output quality, a XML document image on a browser has lower quality than a general document image on desktop publishing. The reason is which output function of a browser has not capability for high quality printing. The W3C developed XSL-FO(XSL-formatting Object) for style sheet formatting and PDL(Page Description Language) as like Postscript is already developed and used widely. In this paper, we designed the Postscript-Converter to get a high quality document image by converting XSL-FO into Postscript format.
