If remodeling is defined as activities that restore the overall function of a building up to the standards currently demanded rather than as a simple replacement or repair of old facilities and equipment, the main task of remodeling should be the reduction in differences between areas, establishment of a functional linkage between departments and setup of a smooth circulation system. Therefore, this study is an analysis of remodeling strategies and construction processes to resolve major tasks of remodeling. Through this research we acquire concluding remarks. 1) The remodeling strategies of equipment-intensive areas can be divided into two measures: utilizing the existing buildings (the main buildings) the most, and of concentrated relocation in the new buildings. The former method is advantageous in that the main building serves as a center in hospital layouts because concentrated placement of the diagnosis/ treatment area and the supply area benefit the overall operation in terms of functions. However, the measure has limits in that it is difficult to install the facilities and equipment of the new demands due to the low ceilings, which serve as a potential challenge in future growth and changes. 2) The latter measure is the one in which equipment-intensive areas and the areas that are absolutely short of space are first placed in the new buildings while other areas (the outpatient area, the administration area and the miscellaneous areas) are in the existing building (main building). Given the possibility of development In the future, concentrated placement in the new buildings can be said to be more effective order to actively address future growth and changes.

Approaching to the era of high energy price and energy sources scarcity, the demand for governmental intervention to mitigate the short-term shocks is highly increasing. When any energy policy is implemented, double-side effects would be derived. To begin with positive aspect, by decreasing energy import, unnecessary currency outflow can be prevented and the resultant saved money will be appropriately allocated. Furthermore, industrial competitiveness will be assured by reducing use of expensive energy. On the contrary, inappropriate energy saving policy may lead to unexpected negative effects that would hinder improvement in productivity due to indiscreet replacing energy by equipments. In order to enhance effectiveness of energy policy, efforts should be made in advance to understand the energy use pattern of each industry sector which composes the economy. Therefore, in this study, an energy input-output method, one of the macroscopic approaches, is applied to analyze energy use patterns of each industry sector in Korea. Using this method, a quantitative assessment is performed to obtain the energy use intensity and the amount of energy uses with respect to energy types.

In this study, the newest technology available to reduce GHG emissions, which can be applicable in energy industries of the future that has large reduction obligations by energy target management and large intensity of GHG emissions, has been investigated by searching the technical characteristics of each technology. The newest technology to reduce GHG emissions in the field of power generation and energy can be mainly classified into the improvement of efficiency, CCS, and gas combined-cycle technology. In order to improve the reliability of the GHG emission factor obtained from the investigation process, it has been compared to the technology-specific GHG emission factor derived from the estimated amount of emissions. Then the GHG abatement measures, using the derived estimation of factor, by using the newest technology to reduce GHG emissions have been predicted. As a result, the GHG reduction rate by technology of CCS development has been expected to be the largest more than 30%, and the abatement rate by technology of coal gasified fuel cell and pressurized fluidized-bed thermal power generation has been showed more than 20%. If the effective introduction of the newest technology and the study of its characteristics is continued, and properly applied for future GHG emissions, it can be prospected that the national GHG reduction targets can be achieved in cost-efficient way.
