Turbo codes are extensively used in current communications standards and have a promising outlook for future generations. The advantages of software defined radio, especially dynamic reconfiguration, make it very attractive in this multi-standard scenario. However, the complex and power consuming implementation of the maximum a posteriori (MAP) algorithm, employed by turbo decoders, sets hurdles to this goal. This work introduces an ASIP architecture for the MAP algorithm, based on a dual-clustered VLIW processor. It displays the good performance of application specific designs along with the versatility of processors, which makes it compliant with leading edge standards. The machine deals with multi-operand instructions in an innovative way, the fetching and assertion of data is serialized and the addressing is automatized and transparent for the programmer. The performance-area trade-off of the proposed architecture achieves a throughput of 8 cycles per symbol with very low power dissipation.

It Is a typical scenario in concurrent engineering/design that different perspectives of each team members participating In the project exist, and those perspectives lead to conflicting decisions. The model 'resolution network' proposed in this work provides system-mediated resolution for all related team engineers to consider to optimize the manufacture in general. This paper focuses on development of the general architecture of the model and a search engine called Mediator to determine a resolution network from a given constraint network. The Mediator manages the constraint network, determines the most optimistic resolution called optimal point in terms of satisfying overall production goal , and use the optimal point to mediate controversial issues among teams. The biggest merit of our model is that it provides teams with resolution with logical and rational reasoning.

하루가 다르게 우리 사회의 모습은 정보화, 디지털화 되어 가고 있다. 이러한 시대적 흐름에 맞추어 정보통신기술교육에 대한 관심과 중요성이 커지고 있으며, 단순히 기능을 가르치는 교육에서 문제해결력을 기르는 방향으로 변하고 있다. 이러한 정보통신기술교육의 변화를 반영하기 위해서는 보다 다양하고 체계적인 교수 학습 모형에 대한 연구가 필요하다. 이에 본 연구에서는 구성주의 교육방법론의 하나로 학습자에게 행함에 의한 학습(learning-by-doing)이 이루어지는 모의 상황을 통해 학습 목표를 달성할 수 있도록 하는 목표기반 시나리오학습(Goal-Based Scenario : GBS) 이론을 초등학교 정보통신기술교육에서 활용할 수 있는 교수 학습 모형을 제안하고자 한다. 즉, 교육현장에서 초등학교 학생들에게 적용할 GBS 교수 학습 모형에 대한 연구로 체계적인 정보통신기술교육의 정착에 도움이 되고자 하는데 의의를 둔다.

This study is about the application of visual structure and presentation of film as one of new methods for design of sequential landscape. The primary objective of the study is to present the basis of applicable and reasonable D니. In applying components of film to DSL, if it is compared with sequential landscape, the film is collection of shots while sequential landscape is accumulation of sceneries. Film and sequential landscape give us a whole meaning different from the meaning itself of a shot or scenery in its experience. The study build a tentative technique of DSL which has the following stages : 1) Goal setting and making out a scenario 2) Analysis and investigation 3) Selection process of definite form 4) Drawing up conti., sketch and notes, It is expected that the technique presented in this study could be a basis for further study of DSL.

This paper describes the development of a pc-based machinery space simulator for training and research, relevant to STCW-95. The detailed mathematical modelling process for the actual machinery is discussed and a method to perform effective education and training for the simulator is suggested. The method includes scenario, procedure, exercise and evaluation. The procedure guides the trainee through a sequence of steps designed to meet a specific goal, showing the trainee what must be done and explaining why The exercise enhances understanding for efficient engine management and enable user to perform research for the machinery. The evaluation shows exercise results and feeds back to instructor how to guide the under-performed trainee.

Geospatial information, which is one of social overhead capital, is predicted as a core growing industry for the future. The production of geospatial information requires a huge budget, so it is very important objective of the policy for geospatial information to prevent the duplication of geospatial projects. In this paper, we proposed a semantic search system which extracts possible duplication of geospatial projects by using ontology for geospatial project administration. In order to achieve our goal, we suggested how to construct and utilize geospatial project ontology, and designed the architecture and process of the semantic search. Moreover, we showed how the suggested semantic search works with a duplicated projects search scenario. The suggested system enables a nonprofessional can easily search for duplicated projects, therefore we expect that our research contributes to effective and efficient duplication review process for geospatial projects.

Since customer's demand is various and product life cycle is getting shorter, many manufacturing company is trying to reduce product development time and cost. For that reason they make an effort to design product on collaborative environment. The various activities in a product development are highly distributed. This distributed nature of the activities implies that teams will be working indifferent place and technical environments. Thus at a given time, teams might work on he same product from different perspectives. This will require efficient communication amongst the various individuals and the various softwaretools that are used by them. Therefore, there is a need for a computerized frame work that can support distributed design such that participants from different backgrounds collaborate towards one common goal. This paper presents the architecture of a collaborative design system. It then reports on the study of computerized frame work focused on collaboration for product development.

In the case of POPs (persistence organic. compounds) that have been release into environment, the goal of exposure assessment is to estimate the individual's total intake through various contact media and exposure pathways. The objective of this study was to estimate human exposure to environmental pollutants using a multimedia/multiroute scenario in an urban area of Korea.

The NAVER is based on a cluster of low-cost personal computers. The goal of NAVER is to provide flexible, extensible, scalable and re-configurable framework for the diverse virtual environments especially for Gamsung research experiments. Personal computers are divided into three servers are according to their specific functions: Render Server, Device Server and Control Server. While Device Server contains external modules requiring event-based communication for the integration, Control Server contains external modules requiring synchronous communication every frame. And, the Render Server consists of 5 managers: Scenario Manager, Event Manger, Command Manager, Interaction Manager and Sync Manager. In this paper, we discuss NAVER as effective distributed system and its application to Gamsung experiment.

지능형 서비스 로봇이란 기존의 로봇과는 다르게 사용자에게 다양한 서비스를 제공하는 로봇이다. 이 로봇은 주변의 상황을 인지하고 그 환경에 적절한 서비스를 사용자에게 제공해야 하므로 여러 가지 복잡한 하드웨어와 기술을 필요로 하고 그에 맞는 요구사항을 추출하기가 더 어려운 상황이다. 본 논문에서는 이러한 상황에 맞춰 요구사항을 추출하고 분석할 때 시나리오 기반이나 목표 기반 등 한가지 기법을 사용한 분석 방법보다는 두 방법을 통합한 목표와 시나리오 기반의 분석방법을 로봇 시스템에 적용해 보고자 하였다. 이를 위해 노인의 생활을 보조하고 지원하는 실버메이트에 직접 적용해 보고 그에 따른 장점과 개선점들을 살펴본다.
