Appliciltion systems focusing class units, as component abstraction based on source code, has insufficient benefit of independency and reuse of elements. Only few effects are acquired, because it is only inclined implementation. We need design pattern to represent not only the problem abstraction but also information and relationship between system elements for generic solutions of specific domain Also, it is essential to software reverse engineering to catch the correct system through examming the cxisting system and utilizing the acquired knowledges as reusable resource. Namely, software reverse engineering for extracting the design pattern is very important because it improves the understand ability for system analysis and design through extracting the design structure of object-oriented system, and provides rich and high leIel reusabilitv through grasping the standard idioms and relationships between components. In this paper, we defined the extraction algorithm for design patterns with standardized, packaged and quantitative measlIIul thruugh applying reyerse engineering into existing ubject Olicnted system. And we designed the reengineering toul including reverse engineering for autumatic extractiun of design patterns ami reuse fur retrieval. editing and rebuilding oi design patterns. Also we applied the algorithms into Java applications.

In this paper, we implemented design pattern retrieval system for efficient management and reusability of design patterns. Pattern is consisted of property information and meta information. Property information is used for similarity measurement on classification and retrieval of patterns. Meta information is used for UML modeling of patterns. We classified design patterns with the empirical scope in addition to Gamma's basic classification.

본 논문은 설계 패턴의 효율적인 관리와 재사용을 위하여 패싯 방식을 이용한 패턴 분류와 패싯 항목과 패턴간의 관련성을 이용한 패턴 검색 시소러스를 구축하였다. 저장소에 패턴들의 관계성을 정의하고 새로운 패턴을 삽입 시 임의의 패턴과의 관계성을 지정해주면 시스템은 이 패턴에 연관된 패턴들을 보여주고 사용자는 패턴과의 관계성을 지정해 준다. 패턴 검색은 입력한 질의를 추론하여 검색할 수 있도록 부울 질의 형식을 사용하였다. 그리고 기존의 시소러스의 중복성과 복잡한 비교시간을 최소화하기 위하여 "Gamma 확장 + 패싯" 분류방법을 이용하여 패턴들을 분류하였고, 본 연구의 검색 결과가 보다 더 정확한 패턴이 검색될 수 있도록 하였다.

UML is used for standardized design, but it has a problem to reuse classified and standardize design information to reuse existing design information. In this paper, the plan to solve these problems design the HYREPnIYbrid REPository) using pattemize design information, and to express together specific property of standardized design information and non standardized design information. It save standardized design information in public area, and non design information in private area. And to express saved design information in repository, UML 1.3 of OMG is used and explained the relationship of the object. Therefore, we designed hybrid repository to express standardized design information and non standardized design information using inheritance concept to remove over adding of pattemized design information.

The various kinds of object-oriented methodology were provided for the development of flexible software. However, they do not automatically make the reusable and robust Object-Oriented software systems. The Object-Oriented mechanism is simply used as the means to obtain the aim. We have heard many complaints from the developers that methods did not give concrete design guidance. Methodologists' effort and make reusable information in the design phase. The relation between the Object-Oriented methods and the design patterns is mutually complementary, and they play a role as a valuable design guidance in the development of the Object-Oriented system. This paper show the interaction between OMT which is most well-known in the Object-Oriented Methodology and Facade, Mediator and Observer designed by Gamma. We suggest the clear solution for concrete design knowledge and reusability of them by applying design patterns to Object-Oriented Methodology.

This paper proposes the efficient system for automatic design of FSS(Frequency Selective Surface) with periodic pattern and frequency characteristics specified by operator. The proposed system derives optimal design parameters through tool for analysis of FSS with arbitrary pattern, DB(Data Base) implemented from limited simulation and measurement data of FSS, and GA(Genetic Algorithm) for optimizing design parameters. FSS analysis tool consists of two analysis tools. One is the simulator for analysis of monolayer FSS that using moment method, another is the tool with approximated analysis method of FSS with dielectric layer. Given pattern configuration and characteristics specified by operators, the DB system searches the best matching FSS, and provides initial genes to GA from the searched parameters, which drastically reduces running time of GA for finding the FSS design parameters. In this paper, the proposed design system is verified through simulation and measurement about FSS with various patterns.

Recently, design patterns have been known to be highly effective and practical. Design pattern is a collection of collaborating classes that captures the application independent behavior of system in a particular domain. By using design pattern, the development time and software quality can be greatly increased. However, systematic development process and detailed instructions of building design patterns have not been studied enough. In this paper. we propose practical intranet structure modeling technique that are based on design pattern. The proposed process consists of the four typical software development phases; analysis, navigation, interface, behavior domain design, and each phase is defined as a logical sequence of development tasks. Since the proposed process is based on design pattern foundation, and can be efficiently produced by applying this process.

Systematically extracting the test patterns of hot spots in an object-oriented software framework is a prerequisite for thoroughly testing the framework's functionality in a variety of contexts in which the framework is extended for reuse. This paper proposes a method for analyzing the design patterns and extracting the test patterns from the interaction test patterns of hot spots in an object-oriented framework. Based on the design pattern of the framework's hot spot, our method captures the object behavior allowed in that hot spot by means of statecharts, which are then used to generate the interaction test patterns and test cases. The generated test patterns and test cases can be applied repeatedly to applications which are built from extending the framework.

본 논문에서는 FMC의 로봇 경로 분석 및 설계를 하기 위해 시뮬레이션을 이용해 FMC의 로봇 패턴을 분석하고 그 결과를 이용해 최적의 로봇 경로를 설계하는 방법을 제시하였다. 전형적인 FMC를 시뮬레이션으로 설계하고 설비에서 신호를 추출 해 순차 패턴 마이닝을 이용해 로봇의 최적 이동 경로를 도출하는 방법을 제시하였다. 이러한 신호의 패턴을 이용한 분석 방법은 로봇의 경로 설계를 도출하기가 용이하여 최적의 경로를 설계하여 FMC에 적용한 결과 기존보다 총 처리량의 증가와 총 처리시간 감소를 가져왔다. 또한 이 방법은 FMC 뿐만 아니라 로봇이 있는 모든 생산라인에 시뮬레이션을 통해 분석이 가능하기 때문에 생산성 향상에 크게 기여할 것으로 기대된다.
