The purpose of this paper is to investigate the three aspects of the construction and common use of old document DB in the foreign countries: i) the processing of old documents, ii) the problem and improvement of DB systems of old documents. and iii) the common use of old document DB. Results from this research are as follows: The National Library of Korea(NLK) copied old documents in the foreign countries from 1982 to 2006 and published the brief catalog. The Reogang Publishing company issued four volumes catalogs of old document in Japan. The National Research Institute of Cultural Heritage(NRICH) investigated old books and published some catalogs of several organizations in Japan. America. France. and all. The National Institute of Korean History(NIKH) investigated old archives and published some catalogs of several organizations in Japan. The characteristics of the Korean Old and Rare Collection Information System(KORCIS) of the NLK, the Old Books Cultural Heritage in Overseas System of the NRICH. and the Korea History DB System and MF Catalog/ Image System of NIKH were described in the DB systems of old documents, the problems of DB systems were checked over and some alternatives were suggested. In the common use of old document DB, KORMARC format and description rules(draft) for archives should be revised to adopt a new standard such as KS editions. and all the institutes involved should thoroughly follow the standards. when creating bibliographic records and digitizing texts. It is necessary to educate and train the specialists of old documents. A government organization should be established to supervise all the procedures of developing technology for sharing digitized resources. using contents. and cooperating with the related internationl organizations and institutes.

For efficient and precise searches in the Web environment, resources should be coded in a structured way. HTML does not cover semantic structure because of its fixed tagging. XML, which has emerged as an alternative standard markuplanguage, uses custom tags that allow structural searching. Therefore, this study aims to compare XML with HTML in terms of their characteristics and retrieval functions. In order to test retrieval functions of XML- and HTML-based systems, we constructed an experimental XML-based system. The XML-based system has several advantages over the HTML system. However, some improvements are needed to make the XML system more comprehensive and effective. First, XML document search engines with user-friendly interfaces are needed. Second, popular Web browsers such as Explorer and Communicator need to support XML 1.0 specification completely. Third, Open DTD format, which will allow information retrieval systems to retrieve documents and compress them into one single format, is also needed to control Web documents more efficiently.

The OGC(OpenGIS Consortium), which is standardization organization of geographic data, have been studied standard for geographic data such as GML and GML based annotation for image and map. Annotation for map is applicable in various ways, understanding about geographic data, decision making and exchange of communication. For instance, Map annotation can be used for highlighting tour-course as symbols or explaining it as text on a map in tourism. This study suggests some annotation methodology for national digital map and presents a simple implementation of it. Firstly, this study suggests a way of updating OGC annotation schema which corresponds with DXF format and creating a GML application schema using the updated OGC annotation schema. Also it suggest a way of converting instance documents of annotated map to VML document with XSLT and VML for display. Later, it is needed to study for supporting another formats as well as DXF format. In addition, it is needed to study for managing the history of updated map entity with annotation in Local governments UIS(Urban Information System) in practical aspects.

Internet becomes absolutely necessary tools due to rapid progress of information technology. Educational correspondence abount an age of information demand is a education focused on a learner and remote education based on information technology. WBI(Web Based Instruction) is a formation that remotly educate a learner using web, possible mutual reaction between instructor and learner, submint various studying material, has a good point to overcome spatial restriction. Internal and external standardization working is accelerated and recently XML security studies are activated using XML which is next generation web standard document format. And XML electronic signature raise interworking between digital signature systems used by various field of using XML document. Using these merit and complementing defect are main contents that users have to pay about Certification service to get CA certificate from 2004 june. This paper propose multiplex Certification remote education agent system using XML digital signature to satisfy security requirement.

As XML becomes the standard of digital data exchange format we need to manage a lot of XML data effectively. Unlike tables in relational model XML documents are not structural. That makes it difficult to store XML documents as tables in relational model. To solve these problems there have been significant researches in relational database systems. There are two kinds of approaches: 1) One way is to decompose XML documents so that elements of XML match fields of relational tables. 2) The other one stores a whole XML document as a field of relational table. In this paper we adopted the second approach to store XML documents because sometimes it is not easy for us to decompose XML documents and in some cases their element order in documents are very meaningful. We suggest an efficient table schema to store only inverted index as tables to retrieve required data from XML data fields of relational tables and shows SQL translations that correspond to XML full-text retrievals. The functionalities of XML retrieval are based on the W3C XQuery which includes full-text retrievals. In this paper we show the superiority of our method by comparing the performances in terms of a response time and a space to store inverted index. Experiments show our approach uses less space and shows faster response times.

Electronic Data Interchange (EDI) has been used for business-to-business communication for almost a quarter of a century. Initial efforts Involved inter-company agreements on how to exchange commercial data, initially as information stored on tape and later as messages sent over dedicated data lines. To avoid having to use different protocols to move data between different companies, various Industry groups identified sets of data that could form the basis of individual agreements. The industry groups also sought to agree the format in which fields in such data sets were interchange so that a company only needed to develop one methodology for decoding information received without resource to human intervention. The XML/EDI specific components are built on top of existing standards for transmitting and processing XML-encoded data. These standards define shared features such as: the standard Internet file storage/naming and data transport mechanisms, file and message transfer formats, the syntax of data coded in XML, the way in which XML files can be validated by an XML parser or document object model generator, the way in which XSL presentation and data evaluation scripts can be associated with parsed objects, the use of rules and data management robots to manage application and repository interfaces.

The fluid performance is one of the key design factors considered during the development of torque converters especially at conceptual design stages. Therefore the design environment that allows an easy access to legacy data of fluid performance could be critical to reduce the design life cycle as well as to increase the performance of the torque converter. In this paper we present a computer-based system that enables designers to utilize massive legacy data for their design of torque converters. For the implementation of the system we propose a standard format for the legacy data and build them into the database to be efficiently shared by designers in the company. Also we provide numerous analysis tools in the system that allow, for example, database management, data viewing and document generation for search, analysis and reporting. In the paper the implementation of the system is introduced in detail with its effective user interface.

XML can supply the standard data type in information exchange format on a lot of data generated in running database or applied programs for a company by using the advantage that it can describe meaningful information directly. Therefore, as it becomes more and more necessary to manage and protect massive XML data in an efficient way, the development of safe XML access control techniques needs a new method. In this study access authorization policies are defined to design access control systems. The findings demonstrated that algorithm suggested in this study improved system performance which was low due to the complex authorization evaluation process in the existing access control techniques. It is consequently proved that the safe XML access control policy presented in this study is in an improved form as compared with the existing access control methods.
