In the electronic records environment, along with discussions on ways to digitize analog records, it is important to prepare preservation strategies for each type of records produced and received electronically. In the same context, there is a need for discussion on applying a preservation format selection system with the goal of long-term preservation of data sets and audio-visual type electronic records other than document types. Audiovisual records must apply preservation strategies appropriate to the characteristics of each medium, such as images, audio, and video. This study establishes unique standards for selecting a preservation format for audio-visual electronic records through analysis of Significant Properties based on literature review, composed audio-type preservation format suitability evaluation items, and proposed a recommended format based on the results of applying them.

Development of hospital information system and Picture Archiving Communication System is not new in the medical field, and the development of internet and information technology are also universal. In the course of such development, however, it is hard to share medical information without a refined standard format. Especially in the department of radiology, the role of PACS has become very important in interchanging information with other disparate hospital information systems. A specific system needs to be developed that radiological reports are archived into a database efficiently. This includes sharing of medical images. A model is suggested in this study in which an internal system is developed where radiologists store necessary images and transmit them in the standard international clinical format, Clinical Document Architecture, and share the information with hospitals. CDA document generator was made to generate a new file format and separate the existing storage system from the new system. This was to ensure the access to required data in XML documents. The model presented in this study added a process where crucial images in reading are inserted in the CDA radiological report generator. Therefore, this study suggests a storage and transmission model for CDA documents, which is different from the existing DICOM SR. Radiological reports could be better shared, when the application function for inserting images and the analysis of standard clinical terms are completed.

Geo-features play a key role in object-oriented or feature-based geo-processing system. So the strategy for how-to-model and how-to-manage the geo-features builds the main architecture of the entire system and also supports the efficiency and functionality of the system. Unlike the conventional 2D geo-processing system, geo-features in 3B GIS have lots to be considered to model regarding the efficient manipulation and analysis and visualization. When the system is running on the Web, it should also be considered that how to leverage the level of detail and the level of automation of modeling in addition to the support for client side data interoperability. We built a set of 3D geo-features, and each geo-feature contains a set of aspatial data and 3D geo-primitives. The 3D geo-primitives contain the fundamental modeling data such as the height of building and the burial depth of gas pipeline. We separated the additional modeling data on the geometry and appearance of the model from the fundamental modeling data to make the table in database more concise and to allow the users more freedom to represent the geo-object. To get the users to build and exchange their own data, we devised a file format called VGFF 2.0 which stands for Virtual GIS File Format. It is to describe the three dimensional geo-information in XML(eXtensible Markup Language). The DTD(Document Type Definition) of VGFF 2.0 is parsed using the DOM(Document Object Model). We also developed the authoring tools for. users can make their own 3D geo-features and model and save the data to VGFF 2.0 format. We are now expecting the VGFF 2.0 evolve to the 3D version of SVG(Scalable Vector Graphics) especially for 3D GIS on the Web.

XBRL is fundamentally defined as a structure that enterprises expand based on KGAAP 2.1 developed by the Korea branch of XBRL. Each enterprise selects its type of business and must check and choose the tag suitable to each enterprise. Since a complicated part such as expanding tag exists, there is a difficulty to prepare document through the step of tag expansion and data input. Although the expressive way of style provides the standards using the presentation structure and label structure provided fundamentally by XBRL, there is a complicated problem of using XBRL Processor. The electronic public disclosure system of the Financial Supervisory Service (DART) and Korea Exchange (KIND, KEDIS) use the Markup Language of SGML, XML and XBRL as format language. The procedure of defining document and process method vary in accordance with the characteristics of each language. This study analyzes the effect by step in accordance with format language of each electronic disclosure system and studies a direction of format language.

In recent years, theories of image and sound analysis have been proposed to work with text retrieval systems and have progressed quickly with the rapid progress in data processing speeds. This study proposes a common representation format for multimedia documents (CRFMD) composed of both images and text to form a single data structure. It also shows that image classification of a given test set is dramatically improved when text features are encoded together with image features. CRFMD might be applicable to other areas of multimedia document retrieval and processing, such as medical image retrieval, World Wide Web searching, and museum collection retrieval.

The purpose of this work is to develop automatic techniques for converting linear, paper-based documents to a non-linear format suitable for use in hypertext systems. The selected document was partially converted to hypertext manually, and a prototype was created using the rules derived from the manual conversion process. The full conversion was divided into three passes: correcting the electronic linear form of the document, generating a listing of the links in the document, and creating the hypertext document. Passes 2 and 3 were entirely automatic. From this study, it may be concluded that many classes of paper-based documents can be automatically converted to hypertext.

As the XML is approved standard language by the UN, the progress which complemented the XML security has being processed rapidly. In this paper, we design and implement the "XML-Signcryption" as a security mechanism to protect the XML document that can operate between other platforms. The signature and encryption which is the standard specification in W3C needs to be able to proceed them separately. Generally the signature and encryption require four times modular exponential operation, however the signcryption only needed three times modular exponential operation. This will benefit overall system effectiveness in terms of cost. And this scheme offers to convenient the user, because the signature and encryption implement as a single XML format. This tool can save the parsing time as a number of tags is few within a document. And also, in this paper, based on a research of Web Services security, we can apply XML-Signcryption to the SOAP message to provide the security services. Based on the XML-Signcryption scheme which provides confidentiality, integrity, authentication and non-repudiation to the XML document and Web Service security simultaneously.

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
