This study was carried out with the aim of analyzing the development and functional changes of Webdewey, which has become a basic tool of classification learning, analyzing it in terms of usability for learners, and suggesting specific ways to improve WebDewey's usability. In order to achieve this research objective, the concepts and principles of UI and usability were first laid out, and Webdewey's structure and key functions were analyzed. Since then, Webdewey's media changes and periodical feature changes have been analyzed. In addition, an opinion survey was conducted on the usability of WebDewey among learners who used WebDewey in the learning process, and proposed ways to improve WebDewey's usability based on the implications and direction of improvement derived from it. In terms of UI, proposals have been made to introduce display methods, visualization devices, the advantages of printed versions, and the development of Korean versions. In terms of the 'Create built number' function, suggestions have been made to improve usability in terms of basic number selection, composite route guidance and error message provision, new reference and route construction, screen and button design, and built-number component guidance.

This paper introduces the development XPERT(XML Query Processing Engine using Relational Technologies) which is based on relational model. In our system we have used a decomposed approach to store XML files in relational tables. XML queries are translated to SQLs according to the table schema, and then they are sent to the relational DBMS to get the results back. Our translation scheme produces AST(Abstract Syntax Tree) by analyzing XQuery expressions at first. And on traversing AST proper SQLs are generated. Translated SQLs can reduce the number of joins by using path information and utilize dewey number to preserve document originated orderings among compoments in XML. In addition we propose the efficient algorithms of XPath and XQuery translation. And finally we show the implementation of our prototype system for the functional evaluations.

The study was carried out for the purpose of identifying implications that should be considered in educating DDC through online within Library and Information Science curriculum. Followed by operating a NCS-based educational course utilizing printed matter and web version of DDC, two tests and survey were conducted to analyze learning outcomes, satisfaction, and preferences by learning tools. The result showed that differences in educational medium do not correlate to educational performance significantly. However, during the learning process, the mainly used medium affects the usefulness, preference and future utilization of the medium. Based on the research results, when designing DDC education using WebDewey in the future, compared to the printed version, relative understanding for utilizing the structure and its items of DDC classification, built numbers and education for understanding Web Dewey interface and function are required.

TV-Anytime은 차세대 디지털 방송을 위한 메타데이타 표준으로 XML 형식으로 기술된다. TV-Anytime 메타데이타는 그 특성상 단일 스키마를 따르며, 규모에 있어서 대용량이다. 그러므로 데이터베이스를 이용하여 메타데이타를 저장하고 관리할 필요가 있다. 본 논문에서는 대용량 TV-Anytime 메타데이타를, 데이터베이스를 이용하여 저장하고 관리하기 위한 저장 엔진을 제안한다. 단일 스키마에 기반을 두고 있다는 점을 고려하여 TV-Anytime 메타데이타의 구조에 적합한 데이터베이스 스키마를 설계하였다. 문서 재조합을 효율적으로 할 수 있도록 노드 번호를 위하여 Dewey 방법을 사용하였으며, 조인 연산을 줄이기 위하여 Path 테이블을 두었다. 저장 엔진은 TV-Anytime 관리 시스템에서 XQuery 엔진과 같은 XML 질의처리기와 연동될 수 있다.

XML은 인터넷 웹문서, EDI 등을 포함하여 다양한 분야에서 활용하는 문서이다. XML은 플랫폼에 독립적이며 문서의 정보를 손실 없이 전송 및 교환이 쉽고 웹상에서 구조화된 문서의 전송이 가능하다. 따라서 시간이 변화함에 따라 XML 문서의 변경에 따른 효율적인 버전 관리에 대한 중요성이 대두되었다. 본 논문에서는 XML문서 버전관리에 있어서 시간적인 정보를 제공하기 위해 이력 데이터베이스의 정보를 이용하고 문서의 빠른 재구성을 위해 Dewey ordering방식을 결합한 새로운 버전번호 관리방식을 제안한다.

This study compares and analyzes the classes in the major special areas in the sociology, called “branch sociology,” included in the Korean Decimal Classification 4th edition and Dewey Decimal Classification 21st edition. Especially it analyzes the related classes of specified areas (branch sociology) of sociology including those of arts and sports, sciences, languages, society, region, etc. class by class. In this analysis two systems show many differences in the classes included and in the locations of some classes. This analysis can be useful for the future revision of KDC.

Constructions and Architecture fields were divided into Architecture engineering and Architecture in the 5th edition of Korean Decimal Classification (KDC), but those were combined in the 6th edition of KDC published in 2013. The purposes of this study are to find problems and to suggest modifications through comparing and analyzing the 5th and the 6th editions of KDC, Dewey Decimal Classification, Nippon Decimal Classification and Universal Decimal Classification. The necessity of reclassification, a long classification number for History of Architecture and addition of categories of traditional building and architectural engineering are required to improve the 6th edition of KDC and the improvements and modifications of those problems are suggested.

This study aims to analyze and compare the structures of auxiliary tables regarding places - for example, Korea using several decimal classification systems such as DDC, UDC, KDC and NDC. For each auxiliary table, the codes were described in detail and the special characteristics were discussed. The common characteristics and the different aspects of different decimal classification systems were investigated as well as divisions of Korea in Korean Wikipedia and an administrative district classification system. This study suggests a new basic summary for the expansion of codes of Korea in auxiliary table in DDC with its principles and options and it will be useful for revising process of many decimal classification systems.
