In this study, the objective is to improve the criteria used for statistical comparison of the VLF tanδ (TD) database and failure rate according to water-tree degradation in underground distribution power cables. The aging condition of the KEPCO criteria is divided into 6 levels using the Weibull distribution, and the "failure imminent" condition is quantified by using the statistical end-point of the lifetime parameter of the VLF big-data group obtained from KEPCO. Moreover, new criteria with a 2-dimensional combination of TD, DTD, and a statistical normalized factor are suggested. These criteria exhibit high reproducibility for the detection of cables in an imminent failure state. Consequently, it is expected that the adoption of the extended VLF-2019 criteria will reduce the asset management cost of cable replacement compared to the VLF-2012 criteria of KEPCO.

Study on the class using XMI Meta model and XML MetaDats has significant difference from the method of Data creation which is widely used. Most of MXL System are focusing on the editor funcition, Database connection and Generation of Markup language. Unlikelly, however, this study has focused on the creation of Markup language of Class MetaData which are extracted from MXI data modedl. In addition to that, the attribute of unit element within the class and the relationship between the classes within the model were set to be given and expressed respectively. For the generation of Markup language, XML schema was used to declare the detail data type.

In these days. a lot of paper are made electronic document using the computer through the spread of computer and internet technology growing up. which is produced in construction project such as form document, report, account, specification and so on. Developed electronic document is distributed energetically through internet. Because existing electronic document is composed of various format, it is difficult that document data is shared and exchanged among the project participating groups in internet. So, it is required that construction-related technical document is made electronic document by standard information system and how to use technical document. Therefore, tins study presents the procedure and method of developing electronic document on technical document using XML technology.

VoiceXML is a standard dialog mark-up language for the neat generation voice applications. The current VoiceXML 1.0 specification is silent on who place outbound calls for push-based voice applications. The push-barred voice applications become very important in modern information systems such as CRM. In this paper, we design and implement an extended VoiceXML platform that supports both inbound and outbound voice information services. We also extend the VoiceXML DTD so as to be able to inbound/outbound fax based on Call Control Requirements of W3C.

Established XML at February, 1998 in W3C by solution about document processing and exchange and reusability to be shortcoming that early web happens using nonstructural document. Existing electron transaction is changing in electronic business form between corporation through XML base message exchange using XML. Necessity about solution that can masticate structured electron transaction of XML base that is used in electron transaction between corporation rose. Structured electron transaction of XML base that is used in electron transaction in treatise that see hereupon efficiently study about XML document editing system that integrate XML Schema editor to masticate XML Schema document that define edit and XML instance editor of user central that can write a book and structure of XML document efficiently do.

The widespreading of XML as a standard for semi-structured documents on the Web opens up challenging opportunities for Web query language. And UML is a graphical language to represent the result of object-oriented analysis and design. In this paper, we introduce an UML-based graphical query language for XML documents. The use of a visual formalism for representing the syntax and semantics of queries enables an intuitive expression of queries, even when they are rather complex. And, it is matched a series of processes to store and retrieve XML documents to OODBMS with the use of an uniform visualization for representing both the content of XML documents (and of their DTD) and the syntax and semantics of queries.

최근 인터넷이 급속히 성장함에 따라 웹을 기반으로 한 학습이 활발히 진행되고 있고, 또한 학교 업무의 효율화를 지원하기 위한 분야에서도 웹이 응용되고 있다. 특히 웹에서 교수를 위한 복잡한 학교 업무의 관리와 학습자료 및 업무 자료를 지원하기 위해서는 확장성과 호환성, 편의성을 가진 XML 형태의 문서가 제공되어져야 한다. 따라서 교수 업무 지원을 위해 XML 문서의 정보들을 효율적이고 정확하게 이용하기 위해 이들 문서를 적절하게 분류하고 저장, 검색하기 위한 방법이 필요하다. 본 논문에서는 XML로 작성된 교수 업무 지원 문서의 저장과 검색을 위한 선행작업으로서, 일반적인 메타 데이터와 DTD 데이터를 정의하고, 이렇게 정의된 데이터를 이용하여 패싯 검색과 구조기반 검색, 키워드 검색을 제공함으로써 사용자는 원하는 문서를 쉽게 검색한 수 있다. 따라서 이를 통해 교수 업무 지원 문서들을 웹 상에서 효율적이고 정확하게 저장하며, 사용자가 원하는 문서를 정확하고 신속하게 검색할 수 있게 하고자 한다.

Since XML (eXtensible Markup Language) was highlighted as an information interchange format, there is an increasing demand for incorporating XML with databases. Most of the approaches are focused on RDB (Relational Databases) because of legacy systems. But these approaches depend on the database system. Countless researches are being focused on DTD (Document Type Definition). However XML Schema is more comprehensive and efficient in many perspectives. We propose a meta-model for XML Schema that is independent of the database. There are three processes to build our meta-model: DOM (Document Object Model) tree analysis, object modeling and storing object into a fixed DB schema using model mapping approach. We propose four mapping rules for object modeling, which conform to the ODMG (Object Data Management Group) 3.0 standard. We expect that the model will be especially useful in building XML-based e-business applications.

The large scale documents of the data repository are utilized to the diverse applications. In the cross-language information retrieval, if the words of a query contain polymorphic meanings, the system needs multilingual corpus to exactly translate to the target words. We constructed the financial comparable corpus, called KFCM(Korean Financial Corpus corresponding to MLCC Corpus), comparing to the MLCC Polylingual Documents which consisted with the 6 European languages. It is independently constructed under the DTD of MLCC comparable corpus, and can be utilized to the cross-language information retrieval. In this paper, we discussed about the application and construction procedures of KFCM which is public domain data.

In this paper, we propose an interpreter, which recognizes the VoiceXML markups, verifies the validation of the document, and interprets the VoiceXML documents using DI parser and the generated AST by the parser. The VoiceXML interpreter consists of DI parser and executor, and the DI parser uses recursive descent parsing technology, and the executor uses FIA (Form Interpretation Algorithm) proposed by VXML forum. This system uses the Java language in order to develop the runtime environment for VoiceXML efficiently, thus this system has portability.
