This study examined how to create 2D basic pattern of individuals by means of 3-D body figure, which is to develop a flat of individual basic pattern directly from the 3-D body scan data of each subject using that of the upper body of a male adult. In terms of methodology, this study adopted 3D body scan data on system and body to make examinations in the following steps: 1. Standard point and line were set on human body, along with 3-D definition points(feature points). 2. PB was created by modifying horizontal and longitudinal section of scan data. 3. Ways to set reserve were established in the findings of PB planar development. Respective developed flat patterns were compared with pattern findings in previous studies by means of sensory evaluation. As a result, it was found that both system and body model are basic pattern and belong to appropriate pattern as semi-tight-fit basic pattern with overall appropriate tolerances. Thus, this study came to a conclusion that it is feasible and valid to develop theories for flat development as considered herein.

Usability is one of the most important concepts regarding software quality. It can be interpreted as the goodness associated with using the software product. This paper distinguishes the goodness of an individual using experience and the goodness of a product for using. This paper proposes a software quality view model which classifies software quality views into two broad categories of end view and means view. End view includes long-term view and short-term view which is classified further into performer's view on software activity and third party's view on software activity. Means view includes intrinsic view and contingency view. The analysis of ISO 25000 Series SQuaRE demonstrates the necessity to decompose product quality model and quality in use model into five models corresponding to the software quality views respectively. The analysis on playability shows that the universal definition of usability may be an illusion. The results provide the theoretical basis to build a comprehensive and consistent body of knowledge regarding software quality, which is consisted with the set of quality models and the theories explaining the relationships among the elements of the models.

Over the past decades, an enormous amount of effort has been expended in laboratory and field studies on concrete durability estimation. The results of this research are still either widely scattered in the journal literature or mentioned briefly in the standard textbooks. Moreover, the theoretical approaches of deterioration mechanisms with a predictive character are limited to some complicated mathematical models not widespread in practice. A significant step forward could be the development of appropriate software for computer-based estimation of concrete service life, including reliable mathematical models and adequate experimental data. In the present work, the basis for the development of a computer estimation of the concrete service life is presented. After the definition of concrete mix design and structure characteristics, as well as the consideration regarding the environmental conditions where the structure will be found, the concrete service life can be reliably predicted using fundamental mathematical models that simulate the deterioration mechanisms. The prediction is focused on the basic deterioration phenomena of reinforced concrete, such as carbonation and chloride penetration, that initiate the reinforcing bars corrosion. Aspects on concrete strength and the production cost are also considered. Field observations and data collection from existing structures are compared with predictions of service life using the above model. A first attempt to develop a database of service lives of different types of reinforced concrete structure exposed to varying environments is finally included.

In various fields of information technology, it is growing up the needs about dynamic content management systems to store and manage SGML(Standard Generalized Markup language) documents in a database system. In this paper, we consider the issue of storing SGML documents that having complex hierarchical structure into a database system, and then propose a data model based on ODMG(Object Database Management Group) object model in order to store SGML documents without loss of information. Because the proposed data model reflects physical element structure and logical entity structure of SGML documents, it is able to store the SGML document in a database system at the system at the element- level granularity without any information loss. And also the proposed data model can be adapted among ODMG-compliant object database management systems. Finally, we will discuss on the implementation details of SGML repository system supports the functionality of automatic database schema creation for any DTD(Document Type Definition0, the functionality of storing the SGML document, the functionality of dynamic document assembly from stored database objects to SGML document, and the functionality of indexing and searching for database objects.

A Visual development framework for embedded system is presented based on virtual prototyping. Embedded systems often are used in life critical situation, where reliability is very important. Time_to_market, correctness, user_friendly_design are another features required for embedded system design. However, embedded systems are today designed with an ad hoc approach that is heavily based on earlier experience with similar products. We believe that new design paradigm is needed and it should be based on the use of formal model and visual system to describe the behavior of the system at a high level abstraction. Virtual prototyping has all the required features. It has the following advantages; correct design, clear interface definition, idea experimentation, increased communication. In this paper, we describe the design and implementation of VIP/Sim(Virtual Prototyping Simulator), a visionary development framework for embedded system design. New feature such as state polymorphism is augmented to the de_facto standard formal language, statechart, for enhanced dynamic modeling. Actual design experience with VIP/Sim is also discussed.

최근 멀티미디어 콘텐츠가 빠르게 확산되고, 초고속 광대역 IP 네트워크 기술이 발전하면서 통신과 방송의 독자적 개별 서비스가 서로 공존하여 통합융합 서비스로 진화발전하고 있다. 대표적 방송/통신 융합 서비스인 IPTV는 통합융합서비스의 가장 강력한 응용분야이며, IPTV와 같은 서비스들이 증가함으로 인해 다양한 인터넷 서비스를 구현하기 위해서 인터넷 프로토콜을 통한 고화질의 데이터 처리에 대한관심이 통신업계의 화두로 등장하고 있다. 본 연구에서는 소규모에서 사용되는 표준 라우팅 프로토콜인, RIP 환경과 대규모 자율 네트워크에서 사용되는 링크 상태 라우팅 프로토콜인, OSPF 환경을 구현하여 IPTV 서비스 중에서 방송 화질의 PSNR값으로 성능을 측정하고 평가하여 효율적인 IPTV 서비스를 위한 네트워크 구축 방안을 제시하고자 한다.

XML이 웹상에서 정보 교환의 표준으로 채택되면서 XML을 데이타베이스의 데이타로 보고 정보를 추출하는 분야가 주목받고 있다. XML은 그래프 기반의 비정형 데이타(semistructured data) 모델 과 매우 비슷하기 때문에 XML 데이타를 그래프 기반의 비정형 데이타 모델로 매핑한 후, 이에 대하여 질의를 처리할 수 있다. 본 논문에서는 XML 데이타에 대하여 스키마 정보를 가지는 DTB(Document Type Definition)를 이용한 질의 최적화 기법을 제안한다. 제안하는 기법은 인덱싱 효과를 내면서도 기존 방법에 비하여 부가의 메모리를 적게 필요로하고, 입력 데이타의 구조를 그대로 유지하기 때문에 다양한 형태의 질의를 효율적으로 처리할 수 있다. 간단한 예제 데이타베이스에 대하여 제안하는 기법의 실험 결 과를 보였다.
