Hyla suweonensis is an endemic species and is designated as the only endangered species I among amphibians in 2012 by the Ministry of Environment, however studies about its habitat are lacking. This study was carried out to analyze habitat of H. suweonensis based on the spatial information using Maxent (Maximum entropy model as a species distribution model. We detected 45 present points until 2013 and 10 environmental variables by literature review for the model. The results showed that $429km^2$ (0.95%) of the study area, which was about 7.75% of the total agricultural area, was high possible habitats of H. suweonensis. The habitat of H. suweonensis was analyzed by over $1km^2$ rice paddy fields that were lower elevations, flat slopes, and not fragmented. The distance from forests and rivers was identified as a factor that affects its habitat possibilities. In order to conserve H. suweonensis, a large area of rice paddy fields should be preserved, and especially the area around forests and rivers would be required more intensive management. In addition, to compensate for degraded habitats of H. suweonensis in urban areas like as Suwon city, considering integrated watershed management strategy could be effective in the perspective of ecological habitat network of H. suweonensis.

The development of information technology has been expected to change the living style and upgrade the living environment. These expectations are somewhat realized, but there are certain groups that will be less benefitted by these upgrades compared to other groups. These phenomena are called digital divide, which is the latest Issue around the world these days. There are several factors that raise digital divide such as gender, education, job, age, income and region. In Korea, the most critical factor may be considered as region but so far this has only been assumed and there has been no empirical surveys about this. This study is proposed to survey the remote rural areas to find out the actual situations of digital divide compared to the urban areas in Korea. And the results will be used as a basic data to make strategies and policies in order to improve the rural living environments.

Chemical catalyst products are applied to various fields such as petrochemical process, air pollution prevention facility and automobile exhaust gas purifier. The domestic and overseas chemical catalyst market is increasing every year, and the amount of waste catalyst generated thereby is also increasing. Most of the used chemical catalyst products, such as desulfurized waste catalysts and automobile waste catalysts containing valuable metals are important recyclable resources from a substitute resource point of view. The recycling processes for recovering valuable metals have been commercialized through some urban mining companies, and SCR denitration catalysts have been recycled through some remanufacturing companies. In this paper, the amount of domestic production and recycling of major catalyst products have thus been investigated and analyzed so as to be used as basic data for establishing industrial support policy for recycling of used chemical catalyst products. Also tasks for promoting the recycling of used chemical catalyst products are suggested.

This study was aimed to derive measures for maximizing ripple effect of construction of overseas industrial complexes on domestic economy. The induced coefficients were estimated for each step of development of industrial complexes by applying the raw data of ICAK and the input-output mode. As a result, for urban service, the fraction of labor costs was high, and for civil engineering, the fraction of profit & loss was high. However, the proportion of intermediate and profit & loss was high in Architecture. Consequently, compare to the same type of overseas constructions, larger effects were seen at urban service in terms of employment, at civil engineering and architecture in terms of business, and at national economy in terms of architecture. These results suggest that in order to maximize ripple effect of construction of overseas industrial complex on domestic economy, it will be needed to seek an order strategy including not only simply sell a land and but also building factories in the industrial complex.

Due to rapid urbanization around the world, various social problems and side effects are occurring. Accordingly, the creation of smart city is being promoted to improve the quality of life of citizens and promote sustainable urban development. In Korea, visions and strategies for the creation of smart city have been presented for each ministry within the government. But they are proposed from the standpoint of each ministry, not from the national level. Therefore, it is necessary to establish a vision and core strategies at the national level. In this study, the problems of Korea smart city were derived, and a smart city vision was established as a solution. In addition, STEEP analysis was conducted through Korea and overseas smart city status analysis and literature review, and based on this, CLDs (Causal Loop Diagrams) were drawn up to derive major smart city strategies. The smart city vision and major strategies proposed in this study are expected to be helpful in setting the direction for future successful smart city creation.

The modular construction method is an off-site construction method using built-in structures from the manufacturing facilities. Modular construction is commonly applied to buildings which have relatively smaller and simpler structures than other types of buildings. Although modular building has emerged in the domestic construction industry as an alternative building strategy, previous researches on the environmental characteristics of modular building has not been comprehensively studied. Thus, this study empirically analyzed the insulation performance of thermal bridge and condensation parts of the modular buildings by using IR image analysis, Air-Surface Temperature Ratio method, and temperature difference ratio. The insulation performance analysis was conducted by comparing a modular building and a RC building in Seoul. The results shows that there was no significant difference between insulation performances of RC building and modular building. Furthermore

As that experienced in other developing countries, Mongolia has already faced multilateral side issues for two decades due to economic growth that created Ger areas or internationally 'Slum', public housing and living conditions for low-income citizens, on the basis of rapid migration from rural areas to urban. Ger areas appear to be the main cause of environmental pollution problems and impending comfortable living conditions of the city's residents by covering more than half area of Ulaanbaatar city. Also, the spread of the Ger areas has many side issues such as prevention of urban development and unaesthetic. Most inhabitants of the areas are on low-incomes, and living in the detached houses or felt yurts (Ger) usually build within a low budget, by themselves or unprofessional people, and by using materials of poor quality. Therefore, Ger areas are an inevitable issue that requires effective, proper and immediate housing policy coordination under the government and even the housing market. Unfortunately housing policies, laws, and projects adopted by Mongolian government have shown inefficient results. The government housing policies, unlike other developing countries did not target low-income households' housing which is the priority issue for two decades. But only in 2014, the Long-term housing policy with the strategy for affordable housing initiated the housing policy for low-income households. This policy has five main broad directions such as redevelopment of Ger area, the land readjustment, public rental housing, new settlements and new city and reconstruction for old apartments, which are rather general and would require tremendous financial resources if each of the directions is implemented simultaneously without prioritization. Therefore this research aims to suggest the efficient and adequate housing policy direction for the low-income households in Ger area based on achievement of other developing countries' strategies, performances and generic characteristic with explanatory models. Also, this research adopts a literature analysis method that uses various research reports, related papers in domestic and international journals, and theses by experts, researchers, public institutions, and agencies.

The purpose of this study is to find out how to effectively utilize the public facilities site that is being used in the new town for the expansion of newly required public facilities, because it is difficult to carry out redevelopment projects in apartment complexes of 1st generation new town due to the rigidity of land use and macroeconomic conditions. This study examined the following three ways to effectively utilize existing public facilities sites for Pyeongchon new town. First, it suggested how to secure the parking lot by deciding multi-dimensional urban planning facility of public facilities such as parks and schools in superblock that lacks parking space of apartment complex. Second, it suggested a plan to accommodate the demands of public facilities required by increasing the building density of existing public buildings in commercial district as an example of the Anyang Tax Office. Lastly, it suggested a way to install additional functions required by users through the reorganization of the existing public facilities and some extensions by examining the Pyeongchon library.
