장덕철 ( Duk Chul Jang ),박장한 ( Chang Han Park ) 한국정보처리학회 2000 정보처리학회논문지 Vol.7 No.3

Automation tools for program analysis are needed in order to program understand and maintain, extract the characteristics of object-oriented program such as class name, member function and data member. In this paper, we carried out design and implementation of the automation tool for effective maintenance of object-oriented software. Being based on Reverse Engineering, this approach extracts class relationship information from C++ source code and generates object- oriented model of class diagram using UML as the standard object-oriented methodology. Therefore, this paper provides developers visualized including class information, definitions of classes, inheritance relationships, set relationships, and simple reference relationships. Finally in this paper, we propose a method that construct class relationship information to table in analysis state and make form of table construction to link form so that developers can perform understanding and maintaining program efficiently. And this method enable to restructure and reuse in object-oriented model.

박영수,장덕철,Park Young-Soo,Chang Duk-Chul 한국정보처리학회 2005 정보처리학회논문지D Vol.12 No.5

For the excellent U web services, the program developers should create both user's client program and the sewer program Recently, the structural alteration of programs are often caused by infernal and external environment concerned with social trends and preferences as well as user's requirements expectations. So, for reducing the development time and workload of XML web service programs, it is necessary to develop the web program generation tools. This paper suggest how to design and implement the web-based XML Tree builder, which was able to provide the information for promptly and easily generating the XML Schema, XML Stylesheet and XML Document through the XML Development Supporting Server System. XML 웹 서비스를 하기 위해서 개발자는 사용자를 위한 클라이언트 프로그램과 서버 프로그램을 함께 개발하여야 한다. 최근 사용자들의 요구와 기대의 증가, 그리고 사회적인 기호와 트렌드 변화 등 내부 ?외부적인 변화가 자주 발생되고 있는 상황에서, 프로그램의 구조 변경이 자주 발생하게 된다. 따라서 XML을 기반으로 한 웹 프로그램 개발의 시간과 비용을 줄이기 위해 웹 프로그래밍을 위한 자동 생성 도구의 개발이 필요하게 된다. 본 연구에서는 개발 지원 서버의 통해 개발자가 XML 스키마, XML 스타일시트 그리고 XML 문서를 쉽고 빠르게 생성하기 위한 정보를 제공할 수 있는 웹 기반의 XML Tree를 설계하고 구현하는 방법을 제시한다.

오상엽(Oh Sang Yeob),장덕철(Chang Duk Chul) 한국정보처리학회 1998 정보처리학회논문지 Vol.5 No.3

Rapid computing environment, change of the application structure, and various user demand will increase the demand of the software development. Version control is helpful to improve productivity using delta, and useful to establish component from existing data of source code. This paper presents the design and implementation of the version control system, which is composed of retrieval system and delta management system. In retrieval system, various retrieve methods are proposed. This methods provides the process methodology with filename, content, size and date. Various retrieve methods are important for the effective delta management. Meta data can be easily composed for the delta management by these methods. Compared with other systems, this implemented version control system has some advantage. First, for delta management, version maintenance for delta management becomes easier by integrating the forward and backward methods. Seconds, delta management part of a project is to unite the forward and backward method. The efficiency of this system is to increased in management. Also, this system supports a technique of using the database and files for project repository and makes version management more effective.

장문석(Jang Moon Suk),장덕철(Chang Duk Chul) 한국정보처리학회 1995 정보처리학회논문지 Vol.2 No.2

일반적으로 퍼지 시스템 모델링에 있어서, 퍼지 규칙을 인식하고 퍼지 추론의 소속함수를 조정하기란 매우 어렵다. 본 논문에서는 인공신경망을 이용함으로써, 자동으로 퍼지 규칙을 인식하고 동시에 퍼지 추론의 소속함수를 조정할 수 있는 방법을 제시하였다. 본 모델은 역전파를 기본으로 한 알고리즘으로 학습하며, 이 방법의 타당성을 로보트 매니퓰레이터를 통해 검증한다. It is very hard to identify the fuzzy rules and tune the membership functions of the fuzzy reasoning in fuzzy systems modeling. We propose a method which canautomatically identify the fuzzy rules and tune the membership functions of fuzzy reasoning simultaneously using artificial neural. In this model, fuzzy rules are identified by backpropagation algorithm. The feasibility of the method is simulated by a simple robot manipulator.

구성요소의 버전제어를 위한 객체지향 검색 프레임워크

오상엽(Sang-Yeob Oh),장덕철(Duk-Chul Chang) 한국정보과학회 1997 정보과학회 컴퓨팅의 실제 논문지 Vol.3 No.4

소프트웨어 재사용과 형상 관리, 그리고 버전 제어를 위해서는 소프트웨어 구성요소를 검색할 수 있는 검색 시스템과 라이브러리의 구성이 중요한 문제로 제기된다. 검색 시스템은 많은 구성요소(component)를 저장하고, 빠른 시간내에 원하는 구성요소를 검색할 수 있어야 하며, 버전제어에서는 해당 구성요소의 검색에 있어서 다양한 검색 방법을 지원하여 검색 능력을 향상시켜야 한다. 본 논문에서는 객체지향 프로그래밍 언어인 C++언어를 이용하여 사용자가 원하는 구성요소를 복합적으로 검색할 수 있는 검색 프레임워크를 제안하고, 모델링하여 구현하였다. 제안한 검색프레임워크에서 사용하는 라이브러리는 facet 분류를 응용하여 하부 표현 구조에 관계없이 라이브러리로부터 구성요소를 검색할 수 있도록 하였다. 이것은 본 논문에서 제안한 TreeSearch 클래스와 검색 함수를 이용하여 관리된다. 본 논문의 검색 프레임워크는 다른 언어와의 인터페이스를 통해 사용될 수 있으며, 이 시스템은 버전 제어를 위한 검색 프레임워크를 제공한다. For the reuse, configuration management, and version control of software, the composition of retrieval systems and library are most important matters, which makes it possible to retrieve the concerned software components. The retrieval system must be suitable not only to store many components but also to retrive the components wanted by the user in the fastest time. The retrieval system will be supported by the various retrieval methods. As a result of that support, the retrival capacity should be improved in the task of retriving the concerned components in the version control. C++ languge, which is one of the Object Oriented Programming Language, is used in this paper, A retrieval framework is suggested, modelled, and implemented so as to retrive the components required by the user in many ways. As for the library used in the retrieval framework suggested in this paper, the components can be retrieved from the library regardless of the infrastructure, applying the facet classification. This retrieval framework is managed using TreeSearch class and the retrieval function. The new retrival system of this paper can be used by the interface with other languages, and this system is to provide the retrieval framework for version control.

It is very hard to identify the fuzzy rules and tune the membership functions of the fuzzy inference in fuzzy systems modeling. We propose a fuzzy neural network model which can automatically identify the fuzzy rules and tune the membership functions of fuzzy inference simultaneously using artificial neural networks, and modify backpropagation algorithm for improving the convergence. The proposed method is verified by the simulation for a robot manipulator.

역옹패설(역翁稗說)연구

장덕철 동방한문학회 1987 東方漢文學 Vol.0 No.3

Up to now we have only had a study on poems and stories of Yoˇgong p'aesoˇl (역옹패설) and on casual commentary designed to entertain and converse with. But we have almost never had a regulor, real, full-scale study on all of it. Therefore, I have classified the whole construction throughout the work and have analyzed in the contents of each field. As a result of studying it, the derived conclusions are as follows. 1. The thought of Yik-chae(益齊) has appered in the contradiction and complications mixed Confucianism with Buddhism. 2. The construction of the contents is made up of his poems and stories, his comments on current events, his knowledge of experience, his impression after reading books, his humor and so forth. And this leads to the form of the inclusive, miscellaneous-recording literature. 3. In the style of descriptive writing, he has paid attention to a historical story, propriety or decorum and the story of a personal criticism. In the respect of the contents, he has expressed his firm belief and polical philosophy leaning towards the stabilization of civil administration and his true deepest feeling of patriotism. 4. In the style of a talk on poetry, an anecdote on poetry has inclusively togather the elements of comments on current literature and casual commentary designed to entertain and converse with. In the point of a criticism of poems, he has taken a serious view of an implication, a reality, a strong individuality of poems. In the criterion of comments oh current events literature, it has disposition(氣象), reading between the lines(言外意), feeling at the sight of a picturesque scene(景中情). And a good expression of these above has led to real expressive image, and is estimated as good, fine poems. 5. The kind of a novel in narrative form is mainly composed of non-realistic story (神異譚) and a funny story(笑話), the latter is the main current. This fact has shown us that the author's eyes of confirming the realities of life have stretched out various ways to the social life, if it has been compared with Yi In-lo's Collection to Dispel Leisure(破閑集), Ch'oe Cha's(崔滋) Collection to Relieve Idleness(補閑集). 6. Yik-chae(益齊) is a moderate, sincere, truthful man, and his view of literature has moderate reactionism(復古風). As we know in the above, the various contents of Yoˇgong p'aesoˇl(역옹패설) has been under wide control of the coherent thoughts towards the spirit of independence of our national consciousness, and has been developed in it. And Yoˇgong p'aesoˇl has assumed the form of a full-scale literary miscellany(雜錄), and this fact has resulted in bringing the specialization of the technical form afterwards. After all. Yoˇgong p'aesoˇl has played a bridgehead important role in completing a more full-scale, affluent literature.
