Recently, in the flow of the digital convergence and u-IT technology development, USN is expected to play a leading role. Currently, it is considered as a previous stage of an activation phase in the life cycle. However, the remarkable growth is predicted in the future. Therefore the political concern and the support are desperately needed for USN to be the core growth engine of the future IT industry. Thus, in this research, we present the condition of the national USN industry by the actual conditions of industry in 2006. And the political suggestion for the new industry monitoring element and essential element of strategy is drawn to contribute to the early activation of the national USN industry.

Recently, automotive industry is attempting to replace steels for automotive parts with light-weight alloys such as aluminum alloy, because of the growing environmental regulations governing exhaust gas and the engine effectiveness of a vehicle. The low cycle fatigue (LCF) and high cycle fatigue (HCF) properties as well as the microstructure and tensile property were investigated on the low pressure cast A356 aluminum alloy wheel, which was followed by T6 heat treatment. The cast microstructure of the alloy influenced significantly on the low cycle and high cycle fatigue behaviors. The rim part of cast aluminum alloy wheel showed higher low cycle and high cycle fatigue strength compared with the spoke part, which should be caused by higher cooling rate of rim part. The spoke part of the wheel showed coarser dendrite arm spacing (DAS) and wide eutectic zone in the microstructure, which resulted in the partial brittle fracture and lower fatigue life time.

To the analysis and discussion whether to conceptualization between the basis and LCM(Life cycle management) of patentability decisions and evergreening through research on patent application strategies and litigation cases. The Stakeholders have said that the LCM and evergreening strategies are an innovative effort to develop new pharmaceuticals, while others say that it is an effort to block generic pharmaceuticals from entering the market and permanently dominate the market by generic pharmaceuticals manufacturers or health economic perspectives. To achieve the goal of research, to discuss for conceptualization LCM and Evergreening strategies through patent application strategies for 14 pharmaceuticals for APIs and case studies for litigations. As a results, the LCM is getting patent rights for the results of research at the initial R&D stage and as such this shall be regarded as part of an effort for technology innovation. However, Evergreening is granting patent rights for the results by making high permission barrier to prevent the market entry of generic pharmaceuticals in the late development period during the pharmaceuticals development process or after their launch. This may lead to the problem of getting weak in health economic aspects and consumer welfare aspects by lowering the market accessibility of cheap generic pharmaceuticals.

Construction industry pays attention to modular construction recently which based on factory production not on labor intensive site production. Since modular construction has high time shortening effect and easiness of demolition and recycling, it has been applied to the temporary residential building. Domestic modular construction market are not activated yet, however, due to the high initial cost to realize modular construction. This study proposes demand-sensitized movable modular building in order to reduce the financial burden. The study compares between RC method building and Modular building which moves building when the demand falls off from Life-Cycle Cost's viewpoint. As a result of the economical evaluation, RC method achieved profits faster than Modular model, but Modular model's gross earnings during the life-cycle are much bigger than RC method. In other words, the result means that the market-sensitized movement of the modular building would be an economci choice in Life-Cycle Costing aspect.

The research team for the virtual construction development was established with the support of Korea Ministry of Construction and Transportation, and KICTEP (Korea Institute of Construction and Transportation Technology Evaluation and Planning). Its aims are to develop system that is to improve productivity & quality, to create a higher value-added business, and to cultivate international competitiveness in the construction industry. The virtual construction system is a design, engineering, and construction management information system that allows the project participants to effectively share the information throughout the construction life cycle with the support of 3D and design information. To achieve this, the research team focuses on developing several systems. First, the team focuses on developing for the pre-planning, the structural engineering, MEP, and the 3D based estimation system. Second, they focus on developing a simulation system for the construction process planning and feasibility study with help of the virtual reality technologies. Third, they focus on developing the CPLM (Construction Project Life-cycle Management) system for managing construction project data, and the decision support system that makes the collaboration among the project participants based on 3D technologies and information. We also focus on developing the SDAI (Standard Data Access Interface), the localized guideline for 3D design, and a training program. In addition, we focus on developing the undeveloped area of the commercial system and building an environment that can support the communication and collaboration in the construction life-cycle rather than developing the existing and commercialized system.

This paper provides a framework for evaluating business information systems. The framework identifies three evaluation domains: IS business value, IS expenses, and IS functionality. Discussions of each category encompass what to be measured, how to measure, and how to judge the measured value. Then, the framework classifies three categories of individual information systems based on IS life cycle: industry-common, industry-similar, and firm-specific. This categorization is used to match the role of an individual system with the focus of evaluation efforts. The framework can contribute to the systematic design of evaluation programs for business information systems.

Shipbuilding is a complex industry which contains a lot of knowledge, technology, and utilities. Hence, the necessity of the PLM (Product Life-cycle Management) system which manages life-cycle information of marine product has been increased. So, many studies related to shipbuilding PLM have been preceded, and there are some cases to be built. To implement collaboration and concurrent engineering of ship designing and manufacturing, interoperability of product data in heterogeneous system is required. Also, sharing and reusing knowledge are important for innovation of business process and productivity of enterprises. Even though many studies related interoperability of product data are going on in varies domain, the application to shipbuilding is deficient. This paper proposes a methodology for management and interconnection of BOM data based on ontology in heterogeneous PLM system of shipbuilding. Using Prot$\'{e}$g$\'{e}$-OWL, we built simple domain ontology of shipbuilding industry, and then, we integrated product information of shipbuilding BOM which is represented with different ontologies. We verified possibility of integration of shipbuilding BOM in heterogeneous PLM, using ontology.

Pursuing sustainable development throughout society and industry and the field of environmental policy, each international organization or nation has performed international standardization projects on environmental management activities for their system as well as environmental assessment for a product such as life cycle assessment (LCA) and life cycle inventory database (LCI DB), and the environmental aspects have been increasingly demanded as crucial evaluation specifications. Moreover, the conventional environmental policy, which represents the direct-control, has been more dependent on the market forces and product itself after the Climate Change Convention., and the Integrated Product Policy (IPP, EU) is applied vigorously to strengthen global competitiveness of a product and to achieve the effect of environmental improvement for it. According to change of the international railway market, the value of Eco-Design has been increasingly important in developed countries including EU. Thus, each country is establishing its own guidelines, software and database for each product, and developing new policies through Eco-Design with practical results in marketing. To react this and develop Korean railway as an environment-friendly industry with priority to other transportation system as well as maintain high place in technology, the direction of RACE software development of main function is introduced, which is exclusively used for EMU to assess both environmental and economic aspects with LCA and eco-efficiency (EE).
