This paper propose a practical algorithm to reuse and expand the objects. This algorithm is based on the Motion Path Modification rules. We focus on reusing of the existing motions for synthesizing new motions for the objects. Both the linear and the nonlinear curve-fitting algorithm are applied to modify an animation by keyframe interpolation and to make the motion appear realistic. We also proposes a framework of the scenario-based 3D image synthesizing system that allows common users, who envision a scenario in their minds, to realize it into segments of a cool animation. The framework is useful in building a 3D animation in game programming with a limited set of 3D objects.

Using mobile bookstore application is increasing in accordance with the proliferation of internet and mobile devices. In this circumstances, the purpose of this study is to explore the factors regarding to mobile bookstore application quality evaluation are effecting to customer satisfaction and reuse intention. Thus information, transaction, design, communication, ubiquitous access, personalization, safety are set as a quality evaluation factor. And it is analyzed the effect of these factors to customer satisfaction and reuse intention with path analysis method. As the result, transaction, ubiquitous access, personalization, safety factors effected customer satisfaction and customer satisfaction effected reuse intention. These results show that user mainly access mobile bookstore application for purchasing book. Thus it is important for mobile bookstore operator to keep the application accessed anytime, and serve personalized information, and simplify transaction process, and intensify security for protecting personal or transaction information.

The purpose of this study is to present a methodology to effectively produce the e-learning contents in two platform types of PC based and mobile based platforms. Currently, the compatibility problem of flash technology widely used in the e-learning content production of existing PC based platform not supporting flash in some mobile platforms is being created while the condition of accompanying inconvenience in learning due to small screen and difference of input interface is being created in case of using the contents for PC even in case of the mobile platforms in which flash is supported. Considering this situation, this study is presenting a content development methodology that can provide services in both platform types based on standard technologies such as HTML 5. In conclusion, the methodology proposed in this study separates the content and the view of learning contents while supporting to enable content implementation using various forms of views based on the content database that has been constructed to show very efficiently characteristics in the content reuse and the multi platform support categories.

This paper constructed component retrieval system for reusability of component. Constructed by thesaurus that use inheritance relation of class for component retrieval, and did so that component retrieval that use Queries may be available. Also, the retrieval result did to become faster retrieval about queries as that show by priority. Retrieved components made efficient component reusability to be possible as that support source code, component information, class diagram etc.

Since T-DMB commercial services have been launched, various broadcasting services such as DMB2.0, which provides interactive data broadcasting services, have emerged. Due to activation of T-DMB services, the needs of the existing video contents as well as new data contents are increasing. Especially, video contents are frequently reused because of the production cost of digitalized contents. In order to solve the problem occurring in the contents reusing process, this paper proposes the method controlling transfer rate by defining a numerical formula and verifies it through simulation.

최근 ATSC DASE 기반의 지상파 데이터방송 실험방송의 성공적인 수행 및 DVB MHP 기반의 위성 데이터 방송에 대한 일반인의 관심이 급속히 증대되고 있는 반면, 매체간 규격이 상이한 관계로 데이터방송 콘텐츠의 메체간 재전송 및 콘텐츠의 재사용에는 어려움이 예상되고 있다. 이에 매체간 호환성을 확보하기 위한 노력으로 공통 규격을 만들려는 Harmonization 활동이 본격적으로 이루어지고 있다. 따라서 본 고에서는 최근의 데이터방송 표준화 동향을 살펴보고 현재 진행중인 Harmonization 현황과 향후 전망을 살펴본다.

In this paper we will propose a domain analysis methodology that uses an extended workflow mechanism based on dynamic modeling to solve problems of a traditional domain analysis on legacy systems. This methodology is called WODA(Workflow Oriented Domain Analysis). Following procedures on WODA, we can identify common/uncommon component, and also extract the cluster of components. It will be effectively reusable on developing new systems with these components. With our proposed component testing metrics, we can determine highly reusable component/scenario on identifying possible scenarios of the particular system. We can also recognize most critical/most frequent reusable components and prioritize possible component scenarios of the system. This paper contains one application of UPS that illustrates our autonomous modeling tool, WODA.

본 논문은 2차원적인 문화재 이미지를 모델링 하여, 대한민국의 시대 별 탑의 차이점과 특징을 분석하고 인공지능을 이용한 3D 복원과 구현을 위한 연구이다. 오늘날 현대 사회에서 디지털 매체 및 정보화 시대에서 여러 산업 분야에 적용이 되고 있다. 기존 2D 이미지를 벗어나 문화재의 모습을 다양한 각도에서 쉽게 관찰해 볼 수 있도록 하여, 3D 형태의 복원이 적합하여 연구를 진행하였다. 최근 인공지능 및 기술의 발달로 문화재 정보를 바탕으로 한 3차원 기술을 사용하여 다양한 데이터들과 프로그램을 이용한 모델링이 가능하다. 현재 문화재 복원은 다양한 자료와 전문가의 기술 및 역사적인 기록물 자료에 의존해 복구한다. 이러한 기법의 문화재 복원은 기록에 남길 수 있는 정보 수집의 효율적인 방법이 될 수 있다. 본 연구는 우리나라의 시대별 탑의 특징을 보여주며, 복원이 실제적이고도 구체적인 다각도의 방향에서 더 정밀하고 정확하게 도출하는데 기여할 것으로 기대된다.

한국 국내에는 GVM(GNFX), WIPI, BREW, MIDP 등 다양한 모바일 플랫폼이 존재하고 있으며, 각 이동통신사별로 서로 다른 플랫폼을 채택하여 사용하고 있다. 이로 인해 개발자는 하나의 콘텐츠를 서비스하기 위하여 각 이동통신사들의 플랫폼에 맞추어서 다양한 버전의 콘텐츠를 개발하거나, 개발된 콘텐츠를 다른 플랫폼에 이식하기 위하여 콘텐츠를 변환하여야 한다. 이러한 이유로 콘텐츠 서비스를 위해 많은 시간과 비용이 소모되고 있으며, 모바일 사용자는 다양한 콘텐츠를 제공받지 못하고 있다. 본 연구팀은 이러한 문제점을 해결하기 위하여 콘텐츠를 자동으로 분석하여 변환해주는 콘텐츠 자동 변환기 시스템을 연구하였고, GVM 콘텐츠를 WIPI Java 콘텐츠로 자동으로 변환해주는 GVMC-to-WIPI Java 변환기를 설계하고 구현하였다. 본 변환기는 한번 개발한 콘텐츠를 단기간 내에 다른 플랫폼의 콘텐츠로 변환할 수 있도록 지원하여, 콘텐츠를 다른 플랫폼으로 이식하기 위한 개발 기간 및 비용을 단축시켜 준다. 또한, 모바일 사용자에게 다양한 콘텐츠를 제공할 수 있도록 한다.

In this paper we constructed semantic net that can efficiently conform retrieval and reuse of object-oriented source code. In odor that initial relevance of semantic net was constructed using thesaurus to represent concept of object-oriented inheritance between each node. Also we made up for the weak points in spreading activation method that use to activate node and line of semantic net and to impulse activation value. Therefore we proposed the method to enhance retrieval time and to keep the quality of spreading activation.
