C++클래스 프로그래밍 지원 도구

오세만,연주흠 東國大學校 1992 東國論叢 Vol.31 No.-

The C++ language is object-oriented programming language which is derived from C language. Although C++ language is based on conventional programming language, it has few drawbacks in use. Particularly, the class programming which enables the reuse of the program is very hard without a supporting tool. When we program the software package using C++ ckasses, we need an information about the relating classes. To accomplish this, we have implemented a system which aids the C++ class programming. The main works of this system are that information about classes in acquired automatically and programmed classes can be added to the class library with very little effort. The system extracts information form classes by parsing the C++ source code and manages class library based on class inheritance hierarchy. And then this information about classes and the class source code are provided when the class library is browsed. So we can do the C++ class programming easily by using the system.

重回歸分析에 의한 勞動者 雇傭豫測에 관한 硏究 : 5人以上 事業體 勤勞者 中心으로 Based on the Employees in the Working Places which have 5 or more full-time Workers

吳世萬,李秉源 동국대학교 경영대학원 1991 經營論叢-東國大學校 經營大學院 Vol.15 No.-

The purpose of this study is to forcast the employment of the employees in the working places which have 5 or more than full-time workers. The main conclusions of this study are summarized as follows: First, the employment is decided on the three factors which are POP(population), GNP/CPI(Gross National Product divide by Consumer's Price Index), and GNP/INC(Gross National Product divide by Income). Also, the flexibilities for each factor are 0.3, 3.7 & 4.6, and GNP is considered the most flexible factor for the employment. Second, it is estimated that 6,268 thousand persons will be employed in 1995, and it is expected that the employment will grow to 2.9% yearly during 6 year 1990∼1995, while the employment has grown up by 7.1% yearly during the last 14 years between 1976∼1989.

AST의 자동적인 구성

오세만,박진기 東國大學校 1990 論文集 Vol.29 No.-

The task of constructing a complier for a particular source language is complex and large. The complexity of compilation process can be reduced if a compiler is designed modularly. So an intermediate from is needed to interface the phases of the compiler. One type of intermediate form is a tree-structured code which is a suitable form for optimization compilers. An AST is a tree-structured intermediate code which does contain the information necessary to next phase of syntax analysis. Most compliers use AST as an intermediate form because of the efficient representation of the source program. The design and obtaining of AST is important in the compiler design process. In this paper, we have implemented the automatic AST generation system. For this work, we designed GDL which is similar to grammar definition in formal language theory and able to describe the structures of AST. And then we implemented the GDLTS that generates the parser constructing the AST automatically according to the specification of GDL. This system can be used as a tool for constructing AST of source program being complied and also used as AST designing tool.

컴파일러 중간언어에 관한 연구

오세만,이양선,박진기 동국대학교 1986 論文集 Vol.25 No.-

최근의 프로그래밍 언어와 기계구조의 급격한 발전은 컴파일러의 자동생산을 요구하게 되었고, 이에 따라 컴파일러의 설계에도 많은 진보가 이루어졌다. 대부분의 컴파일러에서, 원시코드는 기계코드 보다는 중간코드로 번역이 되며 그 중간코드는 특정기계의 목적코드로 번역된다. Syntax-directed방법으로 원시언어에서 기계언어로 직접 번역도 가능하다. 그러나 우리는 중간언어를 사용함으로 해서 몇가지의 이점을 얻을 수 있다. 첫째로 컴파일러의 구성을 서로 독립적인 두 부분으로 나눌 수 있고, 두 번째로 컴파일러의 portability를 한층 더 높일 수 있다. 그리고 세 번째로 중간언어단계에서 기계와 독립적인 optimization을 할 수 있다. 실제규모의 컴파일러를 설치하는 데 있어 중간언어의 선택은 중요한 문제이다. 이 논문에서는 네가지의 중간언어를 다루었고 각 중간언어의 특징을 중간언어의 기준에 비추어 설명하였다. Recently, the programming languages and machine architectures are proliferating. This has led to automate the production of compilers. So much progress in the design of compilers has been made. In most compilers, the source code is translated into an intermediate code rather than machine code. And then the intermediate code is targetted to a specific machine. It is possible to translate directly from source to machine language in a syntaxdirected way. But we can obtain a munber of advantages by use of an intermediate language. They are: (1) The construction of a compiler can be split into two independent phases. (2) The portability of a compiler can be enhanced. (3) A machine independent optimization can be performed at the intermediate language level. The problem of intermediate language selection is very important in implementing a practical scale compiler. In this paper, four kinds of intermediate language are examined and the characteristics of each intermediate language are described according to some criteria.

트리 패턴 매칭 최적화

오세만,김정숙 東國大學校 1995 東國論叢 Vol.34 No.-

It is necessary to optimize target machine independent intermediate code since recent researches on complier development are interested retargetable optimization compiler that can produce the code which can be applied for various target machine. there are various kinds of intermediate languages which are designed for the structures of each compiler. We designed and implemented the intermediate code optimizer that performs the optimization with tree pattern matching techniques by selecting EM intermediate language that is abstract machine code and was used an amsterdam Compiler Kit(ACK). This optimizer system consists of two parts : the tree pattern generator and the tree pattern matcher. The tree pattern generator accepts a table which has 645 optimization patterns and was presented by ACK system. And it generates the tree pattern which is suitable for the tree pattern matcher. The tree pattern matcher produces optimized tree in accordance to constructed tree pattern and performs the actual tree pattern optimization actions. As a result, compare to the most of the traditional string pattern matching methods, it gives about 25% of the code reduction effect for the source code - EM code - and it can reduce re-scan numbers for the basic block. We also found that the optimized code affected to program execution time, and contributed to improve the execution time by about 36%.

이미지 데이터베이스를 위한 정보 검색 시스템의 설계 및 구현

This paper presents design and implementation of an information retrieval system for a large volue of an image database. Our system supports three kinds of queries: attribute-based queries, keyword-based queries, and color-based queries. The attribute-based query is the most-typical query that finds target images based on their attribute values. The keyword-based query is to find target images by referring to their description information their attribute values. Finally, the color-based query is to search for target images by comparing the colors of a query image with those of images in the database. In this paper, we presents the system architecture and approaches adopted in our system for supporting the above three queries effectively and efficiently. We also discuss the user interface of our system that enables users to manipulate our system easily and conveniently.

The purpose of the study was to undertaken to analysis the Grab starting technique between national representive team(3) and Cheju's representive team(3) with 3D cinematography. The conclusions obtained were as follows: Cheju's showed more elapsed time than national representive team on starting block. and more vertical than horizontal direction of COG position, more concentrated vertical velocity & acceleration than forward direction. Therefore It is necessory for cheju's to train balanced trust force in horizontal and vertical direction in grab starting technique.
