This paper provides an overview on development of long-span bridges monitoring in Japan, with emphasis on monitoring strategies, types of monitoring system, and effective utilization of monitoring data. Because of severe environment condition such as high seismic activity and strong wind, bridge monitoring systems in Japan historically put more emphasis on structural evaluation against extreme events. Monitoring data were used to verify design assumptions, update specifications, and facilitate the efficacy of vibration control system. These were among the first objectives of instrumentation of long-span bridges in a framework of monitoring system in Japan. Later, monitoring systems were also utilized to evaluate structural performance under various environment and loading conditions, and to detect the possible structural deterioration over the age of structures. Monitoring systems are also employed as the basis of investigation and decision making for structural repair and/or retrofit when required. More recent interest has been to further extend application of monitoring to facilitate operation and maintenance, through rationalization of risk and asset management by utilizing monitoring data. The paper describes strategies and several examples of monitoring system and lessons learned from structural monitoring of long-span bridges in Japan.

90년대 중반부터 우리나라 산림계정에 대한 연구 결과가 발표되고는 있으나 아직도 체계화된 틀을 갖고 있지 못한 실정이다. 본 연구에서는 2004년에 새롭게 개편된 임업통계연보를 이용하여 산지와 임목을 대상으로 물적 자산계정 작성을 목적으로 하고 있다. 우리나라의 경우 환경경제통합계정체계에 근거한 산림계정 구축의 틀을 마련할 수 있게 된 가장 큰 이유는 2004년 통계 자료에 벌채량에 대한 정보가 추가되었기 때문이다. 자료는 임업통계연보에 기초하였으며 계정 체계는 기초스톡과 기말스톡 간의 증가와 감소로 구분하였다. 산지계정에서의 증가 요인은 조림이고 감소 용인은 벌채이며, 임목계정에서의 증가는 생장이고 감소는 벌채이다. 이들 계정 항목에서 벌채의 원인을 자연발생적인 것과 인위적인 것으로 구분하였다. 또한 계정 항목으로 산입은 불가능하지만 산림의 상태를 평가하는데 중요한 기초 정보는 비고란에 기입하였다. 2003년의 산지 자산계정에서는 산지면적이 감소하는 것으로 나타났고 조림면적보다 벌채면적이 더 많은 것으로 나타났다. 임목 자산계정에서는 벌채량이 전체 임목축적의 0.4%인 것으로 나타났으며 계획벌채량이 피해벌채량보다 3배 이상인 것으로 나타났다. 피해벌채량에서는 인위적 피해로 인한 벌채량이 약 300천$m^3$으로 자연적 피해 벌채량인 55천$m^3$보다 높게 나타났다.

This paper presents a unified model based assessment framework to quantify threats and vulnerabilities associated with control systems, especially in the SCADA (Supervisory Control and Data Acquisition) system. In the past, this system was primarily utilized as an isolated facility on a local basis, and then it started to be integrated with wide-area networks as the communication technology would make rapid progress. The introduction of smart grid, which is an innovative application of digital processing and communications to the power grid, might lead to more and more cyber threats originated from IT systems. However, an up-to-date power system often requires the real-time operations, which clearly implies that the cyber security would turn out to be a complicated but also crucial issue for the power system. In short, the purpose of this paper is to streamline a comprehensive approach to prioritizing cyber security risks which are expressed by the combination of threats, vulnerabilities, and values in the SCADA components.

강릉단오제는 전근대사회에서 전승된 고을축제에 뿌리를 둔 지역축제로서, 1966년 중요무형문화재 13호로 지정되었고 2005년에는 유네스코에 의해 '인류구전 및 무형문화유산'으로 지정되어 한국의 대표적인 전통축제로 평가받고 있다. 일반적으로 이 축제는 전근대의 전통을 잘 간직하고 있는 축제로 알려져 있지만 현재 행해지고 있는 축제의 텍스트를 자세히 살펴보면, 19세기에 전승되었던 축제와는 상당히 다른 구성방식과 내용을 보여준다. 이와 같은 변화는 전승상황의 변화에 따른 문화적 적응의 결과로서, 특히 현재의 텍스트는 문화재지정을 의도한 '원형추구'와 '복원 -재현'의 소산으로 파악된다. 이 글에서는 강릉단오제의 변화상을 보다 구체적으로 검토하기 위해 본디 고을축제였던 강릉단오제의 옛 모습을 현존하는 자료들을 바탕으로 파악하고, 문화재 지정을 즈음해 재구성된 현행 텍스트와 비교해보려고 한다. 이를 위해서 우선 조선시대 고을축제의 존재양상을 살펴봄으로써 고을축제의 보편적 구성방식을 도출했다. 이를 바탕으로 일제 강점 전의 강릉단오제의 절차와 내용을 관련 자료에 대한 종합적 검토를 통해 비정한 뒤, 문화재 지정을 즈음해 그 틀이 짜여진 현행 강릉단오제 텍스트와 대비함으로써 변화상을 드러내고, 몇 가지 중요한 변화의 문제를 짚어보았다. 작업의 결과, 현재의 강릉단오제 텍스트는 축제의 구조, 축제의 시공간, 영신과 송신 및 오신의 제 절차에 포함된 연행의 내용 등의 부면에서, 전통적인 것과 상당히 다른 것이었음이 파악되었다.

The purpose of this paper is to propose the modeling of multiagent based SCM and implement the prototype in the Internet environment. SCM process follows the supply chain operations reference (SCOR) model which has been suggested by Supply Chain Counsil. SCOR model has been positioned to become the industry standard for describing and improving operational process in SCM. Five basic processes, plan, source, matte, deliver and return are defined in the SCOR model, through which a company establishes its supply chain competitive objectives. A supply chain is a world wide network of suppliers, factories, warehouses, distribution centers and retailers through which raw materials are acquired, transformed or manufactured and delivered to customers by autonomous or semiautonomous process. With the pressure from the higher standard of customer compliance, a frequent model change, product complexity and globalization, the combination of supply chain process with an advanced infrastructure in terms of multiagent systems have been highly required. Since SCM is fundamentally concerned with coherence among multiple decision makers, a multiagent framework based on explicit communication between constituent agents such as suppliers, manufacturers, and distributors is a natural choice. Multiagent framework is defined to perform different activities within a supply chain. Dynamic and changing functions of supply chain can be dealt with multi-agent by cooperating with other agents. In the areas of inventory management, remote diagnostics, communications with field workers, order fulfillment including tracking and monitoring, stock visibility, real-time shop floor data collection, asset tracking and warehousing, customer-centric supply chain can be applied and implemented utilizing multiagent. In this paper, for the order processing event between the buyer and seller relationship, multiagent were defined corresponding to the SCOR process. A prototype system was developed and implemented on the actual TCP/IP environment for the purchase order processing event. The implementation result assures that multiagent based SCM enhances the speed, visibility, proactiveness and responsiveness of activities in the supply chain.

As condition-based maintenance (CBM) has risen as a new trend, there has been an active movement to apply information technology for effective implementation of CBM in power plants. This motivation is widespread in operations and maintenance, including monitoring, diagnosis, prognosis, and decision-making on asset management. Thermal efficiency analysis in nuclear power plants (NPPs) is a longstanding concern being updated with new methodologies in an advanced IT environment. It is also a prominent way to differentiate competitiveness in terms of operations and maintenance costs. Although thermal performance tests implemented using industrial codes and standards can provide officially trustworthy results, they are essentially resource-consuming and maybe even a hind-sighted technique rather than a foresighted one, considering their periodicity. Therefore, if more accurate performance monitoring can be achieved using advanced data analysis techniques, we can expect more optimized operations and maintenance. This paper proposes a framework and describes associated methodologies for in-situ thermal performance analysis, which differs from conventional performance monitoring. The methodologies are effective for monitoring, diagnosis, and prognosis in pursuit of CBM. Our enabling techniques cover the intelligent removal of random and systematic errors, deviation detection between a best condition and a currently measured condition, degradation diagnosis using a structured knowledge base, and prognosis for decision-making about maintenance tasks. We also discuss how our new methods can be incorporated with existing performance tests. We provide guidance and directions for developers and end-users interested in in-situ thermal performance management, particularly in NPPs with large steam turbines.

This article analyzes the venture firm based upon the new framework of Dynamic Firm Capability (DFC) to identify the process mechanism. Research methodology includes the case study involving structured interview and data collection from two leading Korean ICT(Information Communication Technology) firms in the same sector (DVR). IDIS, spun off from the university, has accumulated the innovative capability based on the R&D department. On the other hand, KODICOM has retained the technological trajectory in terms of marketing competence. Underlying hypothesis is that a firm should show a idiosyncratic evolutionary pattern by acquiring different complimentary assets(CA). In addition, effective internal process should be matched with the essential characteristics not only at the firm level but also at the sectoral level. By analyzing those two different firms, we will find the strategic successful factors based upon the evolutionary point of view. It is a key contribution of this paper to study on the process mechanism of ventures, and to explain detailed process mechanism by viewing two different characteristics of the firm at the functional level.
