ABSTRACT
This study aims to develop a translator for coexistence of VAN EDI and XML EDI methods in an e-Commerce system. The electronic documents are translated in two steps. At the first step, the translation is performed in the conceptual level. The EDI standard is translated to XML schema. The stage includes the class diagram modelling of EDI standard using the extended mechanism of UML and the following translation to XML schema. And, at second step, the definitive translation is performed. The contents of documents are translated each other for EDI and XML documents. In this step, the information necessary for contents translation is extracted from the XML schema created in the first step, and then the mapping table is constructed using the information. The document translation is completed by this mapping table. A translator developed by this study is superior to the existing flat file mapping method, in terms of maintenance and expansion.

ABSTRACT
A number of application systems for medical information services were developed. However, each of those application systems was developed independently out of consideration for other applications. Therefore, there are many problems in operation of the systems. Users(hospitals) have to prepare communication lines and equipments for using each service redundantly, and facilities for operation of those systems are also furnished individually. Thus, it is necessary to integrate the medical information systems in standardized environment in order to reduce operating costs and upgrade the services. This paper analyzes the methodology for development of an integrated medical information system in common environment and summarizes the result of the integration and standardization. Finally, we studies the directions for expanding the integrated system and activating the services.
