Most of satellite program process consists of mission analysis, thermal, structure, electronics design, and operation, etc. Each step has several steps like design phase, development phase, and verification phase, etc. As to do this kind of process, very high costs and much time are required, further high risk is included. So for solving those difficulties, satellite developers have designed and used satellite simulator system. In early stage of satellite development, simulator system was just used for a fragment of development and verification, so it could not give enough advantage on satellite development. In order to get high advantage on satellite development, full system level simulators which can be used for several steps for development and verification are evolved. So This paper introduces the trend of simulation systems for satellite development and verification used by several satellite developers.

The common lives of the korean people reflect the feeling and emotion of their own world irrespective of rank and class. The folk picture which has the humor, feeling of the korean people, has been with the whole nation throughout times. Therefore it reveals the imaged tradition, recordable character and the truth. It is the folk picture that is the first stream of the game graphic. Because it has its own world built by timeless culture, philosophy, religion, art, and so on. When the game is understood as the reappearance of virtual truth, and the whole new world of the game players, it is really necessary to develop the game graphic with creative plans and artistic value. It is the time to focus on the korean folk picture as a new sources of the contents. Then it is obvious to solidfy the groundwork of the game industry if people at all ages play games as a result of reinterpreting and developing technical tools for the korean folk picture for the present age.

Agents in multi-agent systems (MAS ) are required to achieve their own goals. An agent s goal, however, can conflict with others either when agents compete with each other to achieve a common goal or when they have to use a set of limited resources to accomplish agents divergent goals. In either case, agents need to be designed to reach a mutual acceptable state where they can avoid any goal conflicts through negotiation with others to achieve their goals. In this paper, we consider a BDI agent architecture where belief, desire, and intention are the three major components for agents mental attitudes and represent resource-bounded BDI agents in logic programming framework. We propose a negotiation algorithm for BDI agents solving their problems without goal conflicts in distributed cooperative environments. Finally, we describe a simple scenario to show the effectiveness of the negotiation algorithm implemented in a negotiation meta-language.

Though electronic commerce has grown rapidly in international trade, there is no basic consensus for its concept and rule applied. So WTO has done practice of not imposing customs duties on digital contents and been researching overall on electronic commerce through Work Program while many countries of the world attempt to obtain their interests by stipulating chapter of electronic commerce in their FTAs. This paper has compared and analysed chapter of electronic commerce in all the FTAs which Korea has signed and enforced. Korea's FTA stipulates commonly no customs duties, the other chapter's priority when chapter of electronic commerce conflicts the other chapter, electronic authentication, protection of personal information and consumer protection. But it has weak consistency and framework as it has different provisions for the objects of electronic commerce respectively, reserves classification & applied rule for electronic commerce, stipulates differently on non discrimination treatment and so on. Korea should participate in the research of international organization including WTO and cope actively and elastically by analysing the provisions of electronic commerce of the other countries' FTA such as USA, EU, CHINA and so on.

The purpose of the study was to investigate the mathematical knowledge for teaching (MKT) of pre-service and in-service mathematics teachers on the concept of vector. 80 pre-service and 124 in-service mathematics teachers were asked to perform three questions based on MKT's subdomain. The results show that pre-service teachers have stronger common content knowledge(CCK). On the other hand, in-service teachers have stronger specialized content knowledge(SCK), knowledge of content and teaching(KCT) compared to those of pre-service teachers. The paper proposes CCK, SCK and KCT about the concept of vector and discusses the relationships between subdomains of MKT.

The purpose of this study is two fold. First, we will explore the meaning, spread effect and consideration factors of manufacturing innovation in terms of theoretical perspective. Second, we will verify the status of high performance computing (HPC) utilization policy, and analyze the situation of US and Korea. Manufacturing innovation policy in each country has the objective in common which aims epoch-making enhancing of productivity. Nevertheless it can be characterized as innovation oriented policy rather than simple trial of productivity improvement. For long term growth and employment, the need for reindustrialization instead of deindustrialization should be recognized. Employment may be decreased temporarily and partially due to manufacturing innovation. However net effect of employment increasing will be bigger because of indirect employment. HPC utilization policy has the importance as a separate movement other than as a subset of manufacturing innovation. US government is trying to eliminate the bottleneck elements in adoption of HPC based M&S activity, and to promote the way of problem solving through the mechanism of public-private partnership, in spite of low level of HPC based M&S. In Korea, ecosystem related with the activity of HPC based M&S is needed, and expansion of M&S utilization in manufacturing companies and fostering of M&S supporting institutions will be important for this task.

The feature models representing the common and variable concepts among the software products and the feature configurations generated by selecting the features to be included in the target product are the essential components in the software product lines methodology. Although the researches on the formal semantics and reasoning of the feature models and feature configurations are in progress, the researches on feature model ontologies and feature configuration validation using the semantic web technologies are yet insufficient. This paper defines the formal semantics of the feature models and proposes a feature configuration validation technique based on ontology and semantic web technologies. OWL(Web Ontology Language), a semantic web standard language, is used to represent the knowledge in the feature models and the feature configurations. SWRL(Semantic Web Rule Language), a semantic web rule languages, is used to define the rules to validate the feature configurations. The approach in this paper provides the formal semantic of the feature models, automates the validation of feature configurations, and enables the application of various semantic web technologies, such as SQWRL.

현대사회에서는 도시민의 삶의 질 향상과 관련하여 어메니티의 중요성이 크게 부각되고 있다. 특히 도시의 위생 및 안전과 관련된 환경, 방범 방재, 교통, 치안 등 공공부문의 경우 효율성과 안정성이 담보되어야 한다. 그러나 기존 도시들의 경우 각 부문의 운영이 독립적으로 이루어짐에 따라 도시 운영상의 비효율적 요소들이 나타나고 있다. 이러한 문제점은 최근 활발히 논의되고 있는 U-City 구성요소 중 도시통합운영센터의 체계적인 관리 및 운영을 통해 해결될 수 있을 것이다. 이러한 도시통합운영센터를 위해서는 도시전체를 통합운영, 관리하는 운영방안을 통해 도시의 분산 운영 및 관리에 따른 경제적 손실을 최소화하고, 각 유관기관의 운영체계를 유기적으로 운영할 수 있어야 한다. 또한 도시통합 운영업무에 있어 이해관계를 갖는 유관기관, 조직, 부서 등을 도출하고 각각의 역할과 업무에 대한 분석이 필요하다. 그러나 도시통합운영센터는 도시별 조건이 상이하여 기본적인 공공 분야에서는 기능적인 공통점을 가지고 있지만, 운영기관이 다르고 분야 및 책임, 이해관계로 인해 통합모델로서의 제시가 쉽지 않은 상황이다. 이에 이 연구에서는 기존 도시통합운영센터 및 유사기능수행조직의 운영 사례를 분석하고 이를 중심으로 도시통합운영센터 운영조직의 구성과 기능에 대해 살펴보고자 한다. 기존 도시통합운영센터 운영 사례분석에서는 현재 운영되고 있는 U-City 도시통합운영센터를 대상으로 현황 파악 및 문제점을 도출하고, 유사기능수행조직의 운영지침 또는 운영사례 분석을 바탕으로 도시통합운영센터 운영방안을 위한 운영조직의 구성과 기능을 제시한다.
