Loss of favorable habitats for species due to temperature increase is one of the main concerns of climate change on the ecosystem, and endangered species might be much more sensitive to such unfavorable changes. This study aimed to analyze the impact of future climate change on endangered wild animals in South Korea by investigating thermal sensitivity and vulnerability to temperature increase. We determined thermal sensitivity by testing normality in species distribution according to temperature. Then, we defined the vulnerability when the future temperature range of South Korea completely deviate from the current temperature range of species distribution. We identified 13 species with higher thermal sensitivity. Based on IPCC future scenarios RCP 4.5 and RCP 8.5, the number of species vulnerable to future warming doubled from 3 under RCP4.5 to 7 under the RCP8.5 scenario. The species anticipated to be at risk under RCP 8.5 are flying squirrel (Pteromys volans aluco), ural owl (Pteromys volans aluco), black woodpecker (Dryocopus martius), tawny owl (Strix aluco), watercock (Gallicrex cinerea), schrenck?s bittern (Ixobrychus eurhythmus), and fairy pitta (Pitta nympha). The other 10 species showing very narrow temperature ranges even without normal distributions and out of the future temperature range may also need to be treated as vulnerable species, considering the inevitable observation scarcity of such endangered species.

This study proposes the future strategy of semiconductor companies corresponding to the growth of cloud computing. Cloud computing is the delivery of IT resources such as hardware and software as a service rather than a product, and it is expected to significantly change the IT market. By employing the scenario planning method, this study develops a total of eight scenario cases, and presents the three possible scenarios including the best market, the worst market, and the neutral market scenario. This study suggests the future strategy of semiconductor companies based on the best market scenario (increasing firms' IT expenditure, increasing the complexity and performance of devices, the frequent replacement of devices). The suggested future strategy of semiconductor includes that the semiconductor companies need to strengthen their price competitiveness, secure the next generation technologies, and develop the better capability for market prediction with the growth of cloud computing. This study will help semiconductor companies set up the strategy direction of technology development, and understand the connections between cloud computing and the memory semiconductor industry. This study has practical implications for semiconductor industry to prepare for the future of cloud computing.

The purpose of this study is to develop the evaluation factors for formation of the future - oriented rural residential environment and to derive the importance of this evaluation factors. The main research methods are network analysis using Net-miner, AHP analysis and importance analysis for experts. The main research results are as follows. First, 6 factors for evaluation rural residential environment(environmental-sustainability, communality, self-reliance, aesthetic, enjoyment, settlement), 3 sub-factors of each factors, and key physical facilities(10 for rural center and 28 for rural villages) were derived by literature analysis and network analysis on it. Second, key priority factors that should be considered in physical formation of rural residential environment was deducted by AHP analysis. Improving accessibility of living services in the settlement factor, improvement of garbage collection and wastewater treatment system around the residential area, and ensuring topographic continuity in the environmental-sustainability factor was derived as a priority factors. Third, as a result of evaluation of the importance of physical facilities in the rural residential environment, there was a high demand for cultural welfare facilities in common. However, when compared with the villages where the harmony between the natural environment and the living environment is emphasized, convenience of living and accessibility of transportation were important in the rural center. These results suggest that solving the qualitative conditions as residential environment will help to attract new population. This study will contribute to enhance the qualitative level of the rural residential environment by suggesting strategic priority items when carrying out projects related to the rural residential environment creation in the future.

The purpose of this study was to propose and estimate the architectural planning of general hospital in Korea, for the aged society in the near future. Average life expectancy of Koreans has been lengthened and the percentage of the aged populations is expected to be increased sharply. Therefore, the social problems for the aged occur in various levels, especially in healthcare facilities and medical system due to the weak health conditions of the aged. These problems will become more serious in the near future. However, the architectural planning of general hospital in Korea has not been prepared for the aged society yet. The results of this study were as follows the ward of general hospital should be divided into acute and geriatric wards because of the characteristics of geriatric diseases.

The purpose of this study is to suggest healthcare facilities as ecological architecture. The physical environmental health of human mainly depends on the Quality of architectural natural environment, so it is very important to prepare healing environment on the healthcare setting. This study proceeds to search planning factors of healthcare facilities in ecological architecture through configuration of three main goals. It also explain the importance of ecological planning methods, and suggest a way of architectural planning of health-care facilities in future, through the study of the features and analysis of application methods. The future hospital should provide reduction of the effect on environments, increasing amenity, healing landscape. To create healthcare facilities ecological is essential not only to human health but also human survival.

The space for production, such as studios and control rooms, is a space for TV program production, which is the main function of broadcast. A block planning for such space should be carefully designed, because it can significantly affect the efficiency of production, as well as future productivity and the development and expandability of production. From the results of comparative analysis of 7 local terrestrial broadcasters built since the late 1990s, this study will. propose an ideal block planning for the future construction of local terrestrial broadcasters. Also, the results can be used a basic data when constructing new buildings for local broadcasters.
