As one of promising solutions to overcome high oil price and energy crisis, the construction market of high value-added LNG plants is spotlighted world widely. The purpose of this study is to introduce LNG-RBI system to develop risk assessment technology with RAM(Reliability, Availability, Maintainability) modules against overseas monopolization. After analyzing relevant specific features and their technical levels, risk assessment program, non-destructive reliability evaluation strategy and safety criteria unification class are derived as core technologies. These IT-based convergence technologies can be used for enhancement of LNG plant efficiency, in which the modular parts are related to a system with artificial optimized algorithms as well as diverse databases of facility inspection and diagnosis fields.

Recently, the balance of national properties of governmental offices and departments has been in deficit. Moreover, it has been also increasing rapidly. This study focuses on postal administration business which faces the financial crisis. The purpose of our study is to show devices for value improvement of pelt office. Research was based on a domestic post office which was decided to rebuild in Incheon Bupyeong. Research on domestic and foreign cases were carried out, superior cases for benchmarking was regulated so that these can be applied to the post offices to be built or to be remodeled.

Decline in population and aging have led to the crisis of urban extinction, and the importance of urban regeneration has grown in the country. In addition to the meaning of redevelopment and reconstruction, the government will seek to secure sustainable living conditions, restore the economy, and restore social and cultural functions by utilizing the new technologies based on the efforts to restore the maximum cost to urban buildings and IT technologies.

Among national properties of various governmental offices and departments, we focused on the public finance. Because the financial balance of national properties of governmental offices and departments has been in deficit. This study focuses on postal administration business which faces the financial crisis. The purpose of our study is to show devices for value improvement of postal administration business headquarters of Ministry of Information and Communication. Research was based on case researches and domestic post offices which were decided to rebuild. Problems of domestic postal administration business were first found out. And for its solutions, research on domestic and foreign cases were carried out, superior cases for benchmarking was regulated so that these can be applied to the post offices to be built or to be remodeled.

Current international concerns are the energy crisis due to climate change and depletion of fossil fuels due to global warming. Korea has a very high dependency on energy imports 93%. In Korea, 63% of the country is forested, and a power plant using wood biomass is being built in Korea. Biomass fly ash, a by-product of biomass energy generation, is now being discarded. There is little research to utilize discarded biomass fly ash. Therefore, this study aims to solve the environmental problems, develop new mixed materials, improve the quality and utilize the biomass fly ash, which is a by-product of the industrial waste. As a result of the experiment, the flowability decreased as the replacement ratio of biomass fly ash increased. As the replacement ratio of biomass fly ash decreased, the amount of air content.

Recycling demolished concrete as an alternative source of coarse aggregates for the production of new concrete can help solve the growing waste disposal crisis and the problem of depleted natural aggregates. The purpose of this study is to investigate chloride migration of recycled aggregate concrete containing pozzolanic materials by chloride migration coefficient. The specimens were made with recycled coarse aggregate as various replacement ratio(10, 30, 50%) and metakaolin, blast furnace slag, fly ash is replaced for recycled concrete with mixing ratio 20%. The major results are as follows. 1) Compressive strength of recycled aggregate concrete containing pozzolanic materials increase as curing age and chloride migration decrease. 2) When the replacement ratio of recycled coarse aggregate is 30%, the chloride migration coefficient of recycled concrete containing blast furnace slag, metakaolin shows the similar or lower value than plain concrete at all ages.

This paper considers the case study of the change management and business innovation of the rail construction agency fer overcoming the crisis it faced in early stage. It will provide the suitable innovation techniques of each change stage. Also, each phase it evaluated the change degree of organization culture especially by the six box model of Weisbord and the Quinn's model. For the Period of Change, organization culture will grow about 10% and harmonize with 4 competitive organization culture; community, innovation, hierarchy, product. Only, it discovered that the difference of the current culture and rho organizer' wish is considerable by the Quinn's model. It wilt be able to describe the innovation fatigue which the organizers feel in the change of organization culture. For the successful innovation, it wilt have to be managed properly and the new innovation technique will have to be developed for solving.

Even though the Korean intoner architecture market has constantly developed in the past on the basis of the economic and social growth, it has had a tough time for varied reasons since 1998. Restructuring in the construction industry is required due largely to both the lack of market demand which resulted from the foreign exchange crisis and managerial trouble which is getting worse as time goes by. In actual, as the social necessity for remodeling in skyrocketing, the remodeling is getting more acclaim. That is because old architecture generates a great amount of architectural trash, and it is necessary to look for ways to saute the energy. In the wake of these situations, the remodeling industry is drawing attention as an alternative to the marketable limitations of the existing construction industry. However, it is true that the remodeling market has yet to be activated decisively. Accordingly, the purpose of this paper is to provide a basis for entering into and activating the remodeling market of the interior architecture industry by analyzing the scale and recent conditions of the remodeling sector.

As for the green space construction of the modern parks, landscape design is not only for the aesthetics but its also to promote the spiritual connotation. The appearing of the exemplary type of ecological landscape reflects landscape architects have developed realization and wishes to improve the deteriorating environment and put them into practice. This paper introduces the basic intension of the exemplary type of ecological landscape, and discusses the relative background and ecological aesthetic foundation of the exemplary ecological landscape which appeared under the crisis of urban environment; lists the modern landscape designers practices of the exemplary ecological landscape; studies the developing trend of this practice which becomes multifold along with the reformation of city.

With the world in financial recession, the general trend of global trade is declining. As a result, the world leading shipbuilding industries are confronted with an even more difficult task of mitigating various risks associated with the industries. How well the three shipbuilding industries, Japan, Korea and China, can adapt and manage the risks will be crucial. As the youngest of the top three, the Chinese industry faces greater risks. As it happens to share many factors with that of South Korea in 2004-2005, it is necessary to review and evaluate the risk management plan used by South Korea. This paper presents an evaluation of the risk management plan for shipbuilding industry in South Korea during 2004-2005, considering the financial and political environments at that time. This will help us to structure a plan of risk management for the future.
