Precise and systematic mapping techniques are required for mapping object-oriented artifacts into a platform-specific design. An effective and systematic mapping approach for an adequate platform or programming language in needed, because the characteristics of an initial design are independent from an implementation language and a platform. In this paper, we propose systematic and concrete methods, guidelines, and design patterns that can be used to design business operations at EJB (Enterprise JavaBeans) source code level. We show how various EJB mechanism can be utilized in designing business operations for beans. We believe these proposed methods can yield high-performance EJB applications that can also be well maintainable.

Code reuse in software reuse has several limitations such as difficulties of understanding and retrieval of the reuse code written by other developers. To overcome these problems, it should be possible to reuse the analysis/design information than source code itself. Therefore, this paper present analogical matching techniques for the reuse of object models and patterns. And this paper have suggested the object model and the design patterns as reusable components and the representation techniques to store them. Namely, the contents of the paper are as follows. Analogical matching functions to retrieve analogous components from reusable libraries. And the representation of reusable components to be stored in the library in order to support the analogical matching.

최근 모바일 콘텐츠 산업의 급속한 성장으로 모바일 콘텐츠 작성은 새로운 콘텐츠를 작성하기 보다는 기존 PC기반의 프로그램을 모바일 환경에 맞게 변환하는 추세이다. 모바일 환경에 맞게 변환을 할 때 소프트웨어공학 기법을 적용하면 효율적인 리엔지니어링이 가능하다. 우리는 기존 PC기반의 바둑게임 프로그램을 모바일 환경의 프로그램으로 변환하던 중 많은 문제점과 마주치게 되었다. 우리는 문제점을 해결하고, 차후 코드의 재사용성을 고려하여 디자인 패턴을 고려한 리엔지니어링을 했다. 이러한 리엔지니어링을 하면 모바일 콘텐츠 개발자는 차후 PDA와 같은 다른 뷰를 가지는 프로그램으로의 변환도 손쉽게 할 수 있다. 우리는 기존의 패턴 이용하여 코드 재사용성을 높이는 효율적인 리엔지니어링 기법을 제안한다.

In order to use component for various domain, it need to add tangling code. Component reuse suffers from it. AOP was resolved this problem. We present in this paper a component model, called fractal, that added aspect interface using mixin class named joinController interface. Mixin class are used to combine controller object and interceptor object. we design the dynamic weaver that use the decorator pattern, for increase the reuse of aspect.

네트워크 게임 제작과 관련된 설계 기술은 기업의 보안 사항에 해당되므로 기술 공유가 어려운 실정이다. 인력과 시간이 많이 드는 네트워크 게임제작에서 기존에 작성된 코드를 재사용이 가능하도록 설계하는 것은 중요한 일인데, 코드의 재사용을 극대화하기 위해서 지금까지 사용되고 있는 여러 가지 디자인 패턴들을 사용하는 것은 소프트웨어 설계에 많은 도움을 준다. 본 논문에서는 네트워크 게임 서버에 로그온한 사용자가 차례를 기다려서 게임하는 턴게임 설계와 구현을 통해서, GoF(Gang of Four)가 제안한 행위 패턴들이 어떻게 적용될 수 있는지를 연구하고 자바언어를 이용한 네트워크 게임 개발에 사용될 수 있는 효율적인 API(Application Program Interface)를 제안한다.

웹프로그래밍 환경에서 프리젠테이션 로직을 구성하는 서버처리 웹페이지에는 디자인을 위한 HTML 요소와 로직을 구현하기 위한 서버측, 클라이언트측 스크립팅 요소가 혼합되어 있다. 이와 같은 경우 스파게티 코딩에 의해 웹디자이너와 웹프로그래머간의 작업의 경계가 불분명해지고 디자인과 로직의 구성이 정렬되지 못하는 문제점이 발생할 수 있다. 본 논문에서는 이러한 문제점을 해결하고 웹페이지의 가독성과 재사용성을 향상시키기 위한 리마커블 코드 분리 모델을 제안한다. 이를 통해 웹페이지 수준에서 HTML 요소와 스크립팅 요소를 완전하게 분리하고 관련 연구와 차별화되는 플랫폼 독립적이고 언어 중립적인 웹페이지 모듈화 과정을 소개하고자 한다.

With the increase of interest in ubiquitous computing, image code is attracting attention in various areas. Image code is important in ubiquitous computing in that it can complement or replace RFID (radio frequency identification) in quite a few areas as well as it is more economical. However, because of the difficulty in reading precise colors due to the severe distortion of colors, its application is quite restricted by far. In this paper, we present an efficient method of image code recognition including automatically locating the image code using the hue and saturation values. In our experiments, we use an image code whose design seems most practical among currently commercialized ones. This image code uses six safe colors, i.e., R, G, B, C, M, and Y. We tested for 72 true-color field images with the size of $2464{\times}1632$ pixels. With the color calibration based on the histogram, the localization accuracy was about 96%, and the accuracy of color classification for localized codes was about 91.28%. It took approximately 5 seconds to locate and recognize the image code on a PC with 2 GHz P4 CPU.

In this paper, we considered the received signal of the wideband CDMA systems using turbo code in the multipath channel environments, and analyze the performance of the system. This study is to analyze the performance for the variable system bandwidth according to the number of branches of rake receiver by passing the received signal through a rake receiver with a turbo code in Rayleigh fading channel environments. For the design of receiver in wideband CDMA systems, we presented the efficient parameters for the number of iterative decoding and the number of branches of rake receiver.

In comtemporary interior design, hybrid form causes cognitive turnovers of aesthetics. Especially it offers much possibility to expression techniques in interior design and works as compound system, symbolic aggregate that makes and expands various meanings. The aesthetic ideology of hybrid design can be interpreted through the philosphic concept of art, sublime, reception, representation and explains expression techniques and characteristic in interior design through various transformation and meaning conversion. The expression techinique that is a form of openness, transcendental interpretation that exceed a dupilicate of meaning. can be classified as oxymoron, defamiliarization and interface. The characteristic that is based on those expressions appears as use of complex codes of visual images, decoding strategy, intertextuality of meaning. This research attitude can explain the thinking method of interior design by defining the epistemological scheme that is basically involved in expressional styles with characteristics of hybrid aesthetics. In order to be recognized as the object of aesthetics, hybrid has to be approached by interpretational methods of expression techniques. Consequently the characters of expression techniques in hybrid design can be investigated as one of the methodology in interior design plan.

This study aims to clarify the identity of contemporary Chinese fashion design by examining how the characteristics of Chinese tradition are accepted and presented in fashion under the influences of western cultures. This study performed a literature survey on related works. Also this study performed demonstrative analysis of Chinese daily newspapers (People's Daily and Xinmin Evening News, 2007-2010) and fashion collections by Chinese and Chinese descent designers(2007-2011). The results are as follows: First, China is trying to express Chinese traditional ideas and factors in the design areas, and also trying to achieve an universal generalization. Second, the Chinese designers emphasized traditional ideas and culture in their designs. The Chinese descent designers were affected more by western culture. The common aesthetic consciousness were the beauties of sophisticated and splendorous decoration, vastness and elegance. Also the compromised images, neutral images and antique images were common in both groups. Third, the Chinese designers presented fashion designs on formalized and imitation stage. Also they tried to make a metaphorical stage. The Chinese descent designers showed designs on a metaphorical stage. In conclusion, the contemporary Chinese fashion design should find the way to globalize and identity of the traditional culture code simultaneously.
