무한 인터넷 시장의 영향으로 멀티미디어 자원의 범위 확대와 이를 통한 수익구조를 위한 저작권 관련 기술들이 무분별하게 연구 개.발되고 있다. 콘텐츠 보호기법, 관리기법, 유통기법 등이 콘텐츠 유통업체와 개발자들에 의해 개발되고 있지만 표준이 없는 개발 경쟁으로 인해 저작권 관리 시스템간의 혼란 및 상호 호환성에 문제가 제기되기에 이르렀다. 중복투자로 인한 콘텐츠 유통 구조의 비효율성과 표준이 없는 저작권 관리의 모호성을 해결하기 위해 ISO산하 MPEG 위원회는 MPEG-21 프레임워크를 개발하기 이르렀다. 프레임워크 내부의 데이터 구조는 XML을 기반으로 하고 있으며 저작권 관련 데이터 표준을 제정하기 위해 REL이라는 XML 기반의 저작권 표현 언어를 제안하고 표준화하였다. 그러나 REL을 저작하기 위해 전체 프레임워크를 이해해야 하는 둥의 저작 문제가 발생하여 MPEG-21 내에서 멀티미디어 자원의 저작권 통합 운용을 위한 저작 정보를 쉽고 빠르게 생성할 수 있는 도구가 요구된다. 이에 본 논문은 멀티미디어 자원을 통합 관리하기 위한 REL 문서를 저작하고 표현하며 수정 할 수 있는 저작 도구와 저작된 정보를 운용하는 시스템을 설계 및 구현하였다.

ERP 시스템 개발에 있어 각 기업에 따라 다양한 업무 프로세스가 존재한다. 다양한 업무 프로세스를 ERP 시스템에 모두 포함하기는 사실상 불가능하므로, 기업 업무프로세스에 맞는 커스터마이징의 생산성 및 유지보수가 구축 성공의 중요한 열쇠가 된다. 본 ERP UI 개발도구는 기업 ERP 커스터마이징 시 유지보수 및 생산성 측면에서 Back-end와의 연계, 설계물과의 통합, 생산성 향상을 위한 다양한 도구와 재사용성, 그리고 표준화된 UI 제공으로 표준화 준수와 생산성 증대에 기여하는 것으로 밝혀졌고, 다양한 비즈니스 프로세스 변화에 대응할 수 있도록 개발되었다. 후속연구에서는 Front-end designer에 대한 사용자 편의성 고도화개발과 Front-end generator 개발을 통해 서비스 자동화 및 Front-end와 Back-end의 통합된 개발환경 제공에 관한 연구를 수행하고자 한다.

For Safety Assisted Engineering works, real-time simulators have emerged as a mandatory tool among all the key actors involved in the nuclear industry (utilities, designers and safety authorities). EDF, Electricité de France, as the leading worldwide nuclear power plant operator, has a crucial need for efficient and updated simulation tools for training, operating and safety analysis support. This paper will present the work performed at EDF/DT to develop a new generation of engineering simulator to fulfil these tasks. The project is called SiRENE, which is the acronym of Re-hosted Engineering Simulator in French. The project has been economically challenging. Therefore, to benefit from existing tools and experience, the SiRENE project combines: - A part of the process issued from the operating fleet training full-scope simulator. - An improvement of the simulator prediction reliability with the integration of High-Fidelity models, used in Safety Analysis. These High-Fidelity models address Nuclear Steam Supply System code, with CATHARE thermal-hydraulics system code and neutronics, with COCCINELLE code. - And taking advantage of the last generation and improvements of instructor station. The intensive and challenging uses of the new SiRENE engineering simulator are also discussed. The SiRENE simulator has to address different topics such as verification and validation of operating procedures, identification of safety paths, tests of I&C developments or modifications, tests on hydraulics system components (pump, valve etc.), support studies for Probabilistic Safety Analysis (PSA). etc. It also emerges that SiRENE simulator is a valuable tool for self-training of the newcomers in EDF nuclear engineering centers. As a modifiable tool and thanks to a skillful team managing the SiRENE project, specific and adapted modifications can be taken into account very quickly, in order to provide the best answers for our users' specific issues. Finally, the SiRENE simulator, and the associated configurations, has been distributed among the different engineering centers at EDF (DT in Lyon, DIPDE in Marseille and CNEPE in Tours). This distribution highlights a strong synergy and complementarity of the different engineering institutes at EDF, working together for a safer and a more profitable operating fleet.

최근 하이브리드 전기자동차의 보급 확대에 따라 전기에너지 수요가 증가하고 있다. 본 연구에서는 전기에너지 수요에 대응하기 위해 에너지 하베스팅 기술을 이용해 자가발전이 가능한 3가지 구조의 현가장치 적용 선형 발전 시스템을 ANSYS MAXWELL을 사용하여 전자기 시뮬레이션을 통해 각 구조의 발전 특성을 비교 분석 하였다. 다음으로 각 모델에 대해 상용 PIDO(Process Integration and Design Optimization)툴인 PIAnO(Process Integration, Automation and Optimization)을 사용하여 최적설계를 수행하였다. 3가지 설계변수를 선정하여 실험계획법 기법 중 직교 배열표(Orthogonal Array)를 이용해 도출한 18개의 실험 점에 대해 전자기 해석을 통해 완성한 실험계획법을 바탕으로 근사 모델을 생성하였으며 진화 알고리즘(Evolutionary Algorithm)을 이용한 최적 설계를 수행하였다. 마지막으로 초기 모델과 동일한 해석 조건을 사용해 최적 설계 결과 모델에 대한 전자기 시뮬레이션을 통해 최적설계 결과를 검증 하였다. 각 선형 발전기 모델에 대해 최적의 구조에 대한 발전 특성을 비교한 결과 8pole-8slot, 12pole-12slot, 16pole-16slot 구조에서 최대 발전량은 각각 366.5W, 466.7W, 579.7W로 slot, pole 조합 수가 많아질수록 발전량이 증가하는 결과를 확인하였다.

LiDAR(Light Detection and Ranging) is considered to be a very accurate and useful tool for detection and reconstruction of ground objects. LiDAR data has information about both intensity and x,y,z position of the ground objects. LiDAR data can be collected from both first and last-return, which are called multi-return, with up to 5 different returns simultaneously. In this paper, an approach to reconstruct buildings in urban area using LiDAR multi-return data is presented. The reconstructed buildings are combined with DEM(Digital Elevation Model) produced from DSM(Digital Surface Model) in given area to implement 3D modeling. As a result, it is shown that buildings in urban area can be reconstructed and classified by the integration of the multi-return and intensity data of LiDAR.

The purpose of this study is to propose an integrated curriculum for architectural studio in university to implement BIM process. There have been several BIM education methods occurred in school, but most of them are not successive courses but independent events. To integrate BIM into architectural curriculum successfully, it needs continuous and gradual approach. This study is proceeded by the research of precedent and analysis of key factors in foreign school program. Also fundamental objectives of the current domestic architectural curriculum are categorized to match the BIM process and functionality. As a result of this study, the new architectural design education process integrated with milestone of BIM tool is proposed.

Finding publications that propose alternative methods to animal experiments is an important but time-consuming task since researchers need to perform various queries to literature databases and screen many articles to assess two important aspects: the relevance of the article to the research question, and whether the article's proposed approach qualifies to being an alternative method. We are currently developing a Web application to support finding alternative methods to animal experiments. The current (under development) version of the application utilizes external tools and resources for document processing, and relies on the PubAnnotation ecosystem for annotation querying, annotation storage, dictionary-based tagging of cell lines, and annotation visualization. Currently, our two PubAnnotation repositories for discourse elements contain annotations for more than 110k PubMed documents. Further, we created an annotator for cell lines that contain more than 196k terms from Cellosaurus. Finally, we are experimenting with TextAE for annotation visualization and for user feedback.

This paper is the first one of two-parted research efforts focusing on the modeling of rubber pad forming process. The rubber pad, driven by the pressurized fluid during the forming process, pushes the sheet metal to solid tool half and forms a part to final shape. In this part of the paper, a numerical procedure for the FE analysis of the rubber pad deformation is presented. The developed three-dimensional FE model is based on the total Lagrangian description of rubber maerial characterized by nearly incompressible hyper-elastic behavior under a large deformation assumption. Validity of the model as well as effects of different algorithms corresponding to incompresibility constraints and time integration methods on numerical solution responses are also demonstrated.

The use of computers in architectural professions has grown with the power of easy data management, increased sophistication of standalone applications, inexpensive hardware, improved speed of processing, use of standard library and tools for communication and collaboration. Recently, there has been a growing interest in distributed CAAD (Computer-Aided Architectural Design) integration due to the needs of direct collaboration among project participants in different locations, and Internet is becoming the optimal tool for collaboration among participants in architectural design and construction projects. The aim of this research is to provide a new paradigm for a CAAD system by combining research on integrated CAAD applications with recent collaboration technologies. To accomplish this research objective, interactive three-dimensional (3D) design tools and applications running on the Web have been developed for an Internet-based distributed CAAD application system, specifically designed to meet the requirements of the architectural design process. To this end, two different scopes of implementation are evaluated: first, global architecture and the functionality of a distributed CAAD system; and, second, the association of an architectural application to the system.
