The design methods using patterns have been used in various design fields. Both utility and results have also developed a lot, so that patterns occupy an essential parts in designs. Patterns are often used in various techniques in designing ornaments. However, both time and excessive effort concentrations restricted ornaments designs due to the nature of the craft production techniques by repeated patterns. Therefore, in this study, the traditional craft methods are combined by using computer programs in the applications, repetitions, arrangements of patterns for the manufacturing of ornaments.

디자인패턴은 디자인 경험을 표현하기 위한 새로운 메커니즘으로 미래의 유사 상황에서 다시 적용될 수 있는 과거에 잘 정의된 설계에 대한 정보를 기록하는 것이며 소프트웨어 개발 설계에서 재사용성을 증가시킨다. 그러나 광범위한 관심과 활용에도 불구하고, 패턴명세와 활용은 주로 개발자의 수작업을 통해 이루어지기 때문에 일관된 형태의 분석과 활용이 어렵다. 이로 인해 오류 발생 빈도를 높일 뿐 아니라 프로그램 개발이 어렵고 많은 시간을 필요로 한다. 따라서 본 논문에서는 디자인패턴을 구조화된 전자문서로 표현하기 위한 XML 표기방법과 디자인패턴 활용시스템 구조를 제시한다. 또한 이러한 표기법과 활용구조를 통해 소스코드 자동생성 지원 시스템을 제시하고, 적용 예를 보이고자한다. XML을 이용한 구조화된 문서활용은 소스코드 생성시 사용자들에게 더 작은 코드를 작성하게 만들고, 더 안정된 시스템을 구축한 수 있게 한다. 또한 XML의 다양한 기술에 접목함으로써 패턴 활용을 극대화할 수 있다.

Design patterns are used to utilize well-defined design information. As using these design patterns, we can get re-use in object-oriented paradigm, decrease the time of development and improvement the quality of software. Although these design patterns are widely used among practice, most of design patterns information is manually used, inconsistent and its utilization could be very low. Because the design patterns information that a designer applies does not appear in software, it is sometimes difficult to track them. In this paper, we propose a tool support for design pattern-oriented software development. This tool supports design pattern management, software design and automatic source code generation. The design pattern management has the function for storing, managing and analyzing the existing design pattern and registering new design pattern. The software design has the function for software design with UML and automatically generate design pattern elements. By using this design information, this system can automatically generate source code. In the result to include the tracking design pattern element that is not Included In the existing CASE tools into design information, we can build the stable and efficient system that provides to analyse software, manage design pattern and automatically generate source code.

디자인 패턴은 소프트웨어 설계 시 반복적으로 발생하는 문제를 해결하기 위한 방법을 기술한다. 특히, 객체지향 기술을 기반으로 하는 컴포넌트 설계 시 디자인 패턴을 활용함으로써 특정 설계 문제에 대한 해결책을 재사용할 수 있다. 좋은 객체 지향 설계는 재사용성, 확장성 및 유지보수성을 제공하는 것이며, 디자인 패턴은 좋은 설계에 필요한 구성 요소들의 관계 구조를 제시한다. 본 논문은 객체지향 기반의 컴포넌트 프레임워크 설계 시 프레임워크의 확장성과 구현 컴포넌트의 재사용성을 늘리기 위한 방안으로 디자인 패턴의 활용법을 제시한다. 특히, 알고리즘 재사용의 구조를 제시하는 전략 패턴과 처리 절차 재사용의 구조를 제시하는 템플릿 메서드 패턴의 구조를 비교하고, 분산 통신 컴포넌트 설계 시 전략 패턴의 적용 사례를 보여준다.

Design Patterns are design knowledge for solving issues related to extensibility and maintainability which are independent from problems concerned by application, but despite vast interest in design pattern, the specification and application of patterns is generally assumed to rely on manual implementation. As a result, we need to spend a lot of time to develop software program not only because of being difficult to analyze and apply to a consistent pattern, but also because of happening the frequent programing faults. In this paper, we propose a notation using XML for describing design pattern and a framework using design pattern. We will also suggest a source code generation support system, and show a example of the application through this notation and the application framework. We may construct more stable system and be generated a compact source code to a user based on the application of structured documentations with XML.

Design patterns are known widely by the techniques to improve software qualify. The design patterns are efficient solutions for problems occurring frequently in software development. Recently there are wide researches for design patterns to find them and to verify usability for them. But there are very few researches to define systematic development approaches about constructing application using design patterns. In this paper, we propose an approach for the pattern-oriented software development process using incremental composition for design patterns. For this proposal, first we define a development process using design patterns, propose technique for incremental composition for design patterns and view ports for software in the process. Also we deal with the problem of efficient traceability and maintenance to design patterns in the software system. And we use a feedback framework system as an illustrative example to show how the process can be used to develop the pattern-oriented software. In the development of software, the systematic development approach and usage increase efficiency to develop the system by using design experience and technique early in the development lifecycle. Therefore the system will assure the high stability and reusability and offer the low cost and time for development.

This paper will propose the efficient method that should be designed to utilize the design pattern of GoF(Gang of Four) for implementation of LBS(Location Based Service) mobile system. The design method proposed by this paper can design and implement system interface using creational patterns, structural patterns and behavioral patterns of design pattern from the user and mobile system viewpoint. The design method using design pattern can show increasing reusability of module and software, abridging the development time, minimizing the maintenance and decreasing the efficiency of memory of system to software development. Therefore, we used a design pattern in order to change the middleware applying geographic information system from mobile environment. Finally, the mobile system applied to design pattern shall contribute to showing high stability and reliability, improving reusability and scalability of module and software and developing efficient LBS mobile system.

XML(eXensible Markup Language)은 차세대 인터넷 기술의 대표적인 기술 요소로서 현재 놀라운 속도로 발전하고 있으며 다양한 인터넷 응용분야에서 적용하고 있다. 이런 추세는 XML 어플리케이션을 복잡화, 대형화시키고 있으며 이로 인하여 XML 어프리케이션 개발과 유지 보수가 점점 어려워지고 있다. 이러한 문제점을 해결키 위해 객체지향 개발 방법론애 적용되어온 디자인 패턴(Design Patterns) 개념을 XML 개발 관련 분야에 적용시키는 연구가 이루어지고 있다. 본 논문에서는 XML 디자인 패턴 중 DTD(Document Type Definition) 모델링 시 발생하는 모호성(Ambiguity) 문제를 해결키 위한 패턴과 DOM을 효율적으로 처리하기 위한 문서 구조 트리 운행 및 접근 패턴을 제안한다. 이 패턴들을 활용한다면 DTD 설계 및 DOM(Document Object Model)을 처리하는 단계에서 재사용이 가능해져 개발된 기술들을 공유 가능하며 시스템 디자인 시에 발생 가능한 문제점들을 사전에 해결할 수 있다.

A purpose of the object-oriented programming is to promote reuse and development time, and to improve software quality. A way for this purpose is using a design information well-defined and tested in previous time when developing software. Such design information is called design patterns. The design patterns are descriptions of abstract solution to recurse software design problems In a systematic and general way. But because the design patterns are descriptions of abstract solution, the specification and application of patterns generally rely on manual implementation and is applied to various forms. As a result, we need to spend a lot of time to develop software program not only because of difficulty in analyzing and applying to patterns consistently, but also because of the frequent programing faults. And because the applied design patterns don't express inside application visually, it is difficult to analyze and test for this design patterns. In this paper, we propose automatic source code generating technique to be able to efficiently apply the element of design patterns when developing application. And we show a way to analyze and use the applied design patterns in application. As a result, the design patterns in application provide the consistent structure and efficiency, and make analysis and using effect increased.
