Nuclear power plant construction project can be called essential to establish a systematic project management system compared to other construction projects, taking into account the size and complexity and safety. To develop into a project management system for the Korea situation with the ongoing construction of the nuclear power plant was directed to promote nuclear power project management. In this paper, we introduce a comprehensive project management system for nuclear power projects. Currently considering the nuclear life cycle design, construction, and was developed by considering the flow of information to operate, and test each step linkage. The systems in English were developed to meet owner's requirements for advancing into overseas projects. Another point is that the systems were developed by management module, so that functions of each area can be selectively applied. It is expected that the system will establish itself as one that can be used for the entire lifecycle of nuclear power plants through gradual and systematic establishment of necessary data.

This study aims to develop an approach to construct IWSDB for National Defense CALS. Along with the introduction of Korean version of CALS conception, it is essential to analyze the national defense system with a new information technology for the construction of IWSDB. A long-tenn goal of CALS is to construct fully Integrated Data Environment (IDE) and establish IWSDB for the application of CALS conception to the life cycle management of weapon system. IWSDB is a set of databases that contain digital data. It supports common interface of data objects and databases throughout the life cycle management of weapon system, including design, engineering, analysis, manufacturing, operation, and logistics. etc. The goal of this study is threefold. First, we propose a right direction for the establishment of Integrated Data Environment. For the integrated database technology, we use the five schema architecture and the distributed object oriented technology that will lead to the "share of data." Second, we present the most effective IWSDB architecture for defense CALS, which will provide the efficient data sharing by business process modeling. Third, we suggest that IWSDB should be constructed based on the process which is related to the acquisition and logistics of weapon system for the national defense, and at the same time it should be implemented with GITIS for government agencies and CITIS for the industries in order to obtain the efficient data sharing.

기후변화는 지구환경 시스템을 구성하는 모든 권역에 영향을 미치며 각 권역은 서로 비선형적인 상호작용을 통해 다시 기후변화에 영향을 미친다. 따라서 기후와 지구환경 시스템 사이의 피드백 과정을 종합적으로 분석하고, 변화특성을 진단하여 예측할 수 있는 통합적인 연구가 필요하다. 그러나 현재까지는 기후변화에 따른 지구환경 시스템의 특정 권역의 변화에 대해서만 연구를 진행하고 있어 기후 환경 상호간의 연계 연구 지원이 미흡한 실정이다. 따라서 본 연구에서는 기후 환경 변화를 종합적으로 분석하고 예측하기 위해 자료 저장, 관리 및 배포를 지원하는 GIS기반의 통합DB 관리시스템을 개발하였다. 통합DB 관리시스템은 VB.NET 2005와 지도 기반의 공간 표현을 위한 ArcObjects 컴포넌트를 이용하여 개발하였다. 먼저 기후 환경 전문가의 요구사항을 고려한 연구 대상 및 자료를 선정하였고, 자료 관리 및 활용 방법을 정의하였다. 또한 연구 자료의 효율적인 검색을 위하여 데이터를 표준화하였으며, 이를 적용한 데이터 모델링을 통하여 기후 환경 DB와 자료의 이해도를 높이고, 공간적 상관관계 분석을 위한 GIS DB를 구축하였다. 구축된 DB를 기반으로 사용자에게 DB의 다양한 검색 및 접근을 통해 자료에 대한 세부적인 정보를 제공하고 자료의 배포가 가능한 프로토 타입의 통합DB 관리시스템을 개발하였다. 이러한 GIS기반의 기후 환경 통합DB 관리시스템은 효율적인 자료 관리는 물론 자료를 배포하는 환경을 제공 할 수 있으며, 미래의 기후변화를 종합적으로 진단 및 예측 하는데 기여가 클 것으로 판단된다.

As the product lifecycle is getting shorter and various models should be released to respond to the needs of customers and markets, automation-based flexible production line has been recognized as the core competitiveness. According to these trends, system vendors supply cell-level systems such as FMC(Flexible Manufacturing Cell) that is integration of core functions of FMS(Flexible Manufacturing System) and RMC(Reconfigurable Manufacturing Cell) that can easily extend components of FMC. In the cell-based environment, flexible management for shop floor composed of existing job shop, FMCs and RMCs from various system vendors has emerged as an important issue. However, there could be some problems on integrated operation between heterogeneous cells to use vendor-specific cell controllers and on seamless information flow with high level systems such as ERP(Enterprise Resource Planning). In this context, this paper proposes process management systems supporting integrated shop operation of heterogeneous multi-cell based flexible manufacturing environment: First of all, (1) Integrated Shop Operation System to apply the process management system is introduced, and (2) Multi-Layer BOP(Bill-Of-Process) model, a backbone of the process management system, is derived with its data structure. Finally, application of the proposed model is illustrated through system implementation results.

With an annual growth rate of about 30%, wind energy systems, such as wind turbines, represent one of the fastest growing renewable energy technologies. Continuous structural health monitoring of wind turbines can help improving structural reliability and facilitating optimal decisions with respect to maintenance and operation at minimum associated life-cycle costs. This paper presents an integrated monitoring system that is designed to support structural assessment and life-cycle management of wind turbines. The monitoring system systematically integrates a wide variety of hardware and software modules, including sensors and computer systems for automated data acquisition, data analysis and data archival, a multiagent-based system for self-diagnosis of sensor malfunctions, a model updating and damage detection framework for structural assessment, and a management module for monitoring the structural condition and the operational efficiency of the wind turbine. The monitoring system has been installed on a 500 kW wind turbine located in Germany. Since its initial deployment in 2009, the system automatically collects and processes structural, environmental, and operational wind turbine data. The results demonstrate the potential of the proposed approach not only to ensure continuous safety of the structures, but also to enable cost-efficient maintenance and operation of wind turbines.
