데이터베이스에서 기초정보로 포함되는 여러가지 수학 기호와 수식은 일반 문자들과는 다른 독특한 처리 방법을 필요로 한다. 워드프로세서에 포함되어 있는 수식 편집기가 이런 기능을 처리하는 대표적 예인데, 과학기술분야에서는 이전부터 TeX과 Tex의 매크로 패키지인 LaTeX의 규칙이 많이 이용되고 있다. 이외에도 한글의 수식편집기에도 사용되는 eqn, SGML계열의 수식 DTD등 수식표현을 위한 문법은 여러가지가 있다. 과학기술분야의 출판물이나 학술지 제공 서비스는 웹상으로 옮겨가는 추세이며, 다양한 애플리케이션간의 데이터 교환 언어로 XML이 부상하고 있다.

Represent of mathematical formula used within system handling document that is nonstructural in existent document editing system that is used in electron document processing that use computer is represented or processed by method that is nonstructural of image or text or etc. Such mathematical formular causes relative inconvenience to readablility and reusability of document and processing and exchange of document. Therefore, document editing system is required that can overcome such nonadvantage and apply MathML mathematical formula structure on efficiently structural document. Therefore, designed and implemented that document editing system for structural document creation of XML base that can mathematical formular editing of MathML base in this paper.

The Compared to general sentences, the Equation uses a complex structure and various characters and symbols, so that it is not possible to input all the character sets by simply inputting a keyboard. Therefore, the editor is implemented in a text editor such as Hangul or Word. In order to express the Equation properly, it is necessary to have the learner information which can be meaningful to interpret the syntax. Even if a character is input, it can be represented by another expression depending on the relationship between the size and the position. In other words, the form of the expression is expressed as a tree model considering the relationship between characters and symbols such as the position and size to be expressed. As a field of character recognition application, a technique of recognizing characters or symbols(code) has been widely known, but a method of inputting and interpreting a Equation requires a more complicated analysis process than a general text. In this paper, we have implemented a Equation recognizer that recognizes characters in expressions and quickly analyzes the position and size of expressions.

The design of distrbuted systems is difficult to achieve as the execution patterns of distrbuted systems are typically more complex than those of non- distributed systems. Thus, research toward the development of design methods for distributed systems is quitely needed. As object-oriented systems and distrbuted systems share similar properties, the combination of these two is somehow natural. In this work, a design of distributed systems is introduced. The goal of the method in this paper is to provide assistance to the process of specifying a formal object- oriented specification from graphical representation specification inputs such as data flow diagrams, state transition diagrams and Petri nets. It addresses the extraction of objects, operations and reationshipsfrom the problem domain with emphasis on the specification of the characteristics of distributed systems. This object identification method is supported by a knowledge base that provides for the automated analysis and reasoning about objects and their relationsships. The final object model is represented in a format which provides a formal mechanism for reprsenting the object information.

생산성 제고를 위하여 생산 현장에서 사용되는 여러 가지의 자료 즉, 다양한 형식의 화상(Image), CAD 자료, 도면, 표, 수식, 각종 문서 양식 및 문안들을 관리해주는 시스템이 필수적이다[1]. 그러나 다양한 종류의 자료들이 격리되어 관리되고 있는 상황에서는 원하는 정보를 찾거나, 자료간의 관련성을 알아내는데 많은 어려움을 겪지 않을 수 없다. 따라서 생산과정에서 필요한 여러 가지 자료들을 생성, 편집할 수 있는 도구와 각 자료들간의 관련성을 생성, 편집하는데 도움이 될 수 있는 방안, 마지막으로 생성된 여러 자료를 쉽게 찾도록 도와 주는 기능이 요구된다. 이와 같은 기술정보관리를 효율적이고 통합된 형태로 수행하기 위하여, 본연구에서는 기술정보관리시스템(TIMS : Technical Information Management System)을 구축하였다. 기술정보관리시스템은 개별 자료의 생성, 편집 및 개별 자료의 공유를 통한 복합문서 작성 부분, 개별 자료들 간의 관련성을 자동관리해 주는 부분 그리고 개별 자료들 간의 관련성을 통한 자료검색 부분으로 구성되어 있다. 본 논문에서는 기술정보의 효율적인 작성, 사용 및 관리를 지원하기 위한 통합 시스템의 각 구성부분에 요구되는 기능들과 전체 시스템의 효율성을 증대시키기 위한 방안을 논하였다. 격리되고 인력에 의존에 온 기술정보의 효율적인 작성, 사용 및 관리를 방대한 양의 자료들 속에서 통합적이며, 적합한 형태로 자동관리해줌으로써 생산성 제고에 기여할 수 있는 시스템으로 사용될 수 있을 것으로 기대된다.

This research is for implementation of a software that can convert Hangul format file to $T_EX$ format file. Hangul is a word processor that has widely been used in Korea. It is known that Hangul is relatively easy of typing in equations and tables in preparing a paper draft. $T_EX$ has been developed as a computer programming language for preparing and publishing documents. Documents are first typed in with a plain text editor with $T_EX$ commands and then is compiled and linked. The software implemented in this research converts Hangul format files which are written under the specific format of a journal to $T_EX$ format file with the given style specific file. It converts special symbols, texts, tables, equations, and paragraph formats. We have used Hangul format of Journal of the Korean Data & Information Science Society (JKDISS) and the style file of $T_EX$ for the beta-test for the software.

A lot of accumulated data of many quantity exist within a institution or an organization, but most data is remained in form of standardization as each institution or organization. There are difficulty in exchange and share of information. New concept of knowledge information resource management to overcome this disadvantage was introduced, and the digitization of knowledge information resources to share and manage accumulated data is been doing. Specially, in science technic or education scholarship it, the tendency that importing XML to process necessary data to exchange and share of knowledge information resources structurally, and limitation of back for search and indexing or reusability is happened according as expression of great many mathematics used inside electron document of these sphere is processed to nonstructural data of image or text and so on. There is interest converged in processing of mathematics that use MathML to overcome this, and we require the solution to be able to process MathML easily and efficiently on structural document. In this paper, designed and implemented of XML document editing system which easy structural process of electronic document for knowledge information resources, and create and express MathML easily on structural document without expert knowledge about MathML.
