최근에 이르러 농촌 인구의 도시유입으로 도시의 주거공간이 절대적으로 부족해지고 있으며, 이는 대도시의 아파트 가격 상승을 유발하는 등 부수적인 사회/경제적 문제를 일으키고 있다. 정부나 지방자치단체에서는 이러한 문제를 해결하기 위하여 대규모의 신도시 개발계획을 추진하고 있으며, 이러한 신도시 개발은 도시화로 인하여 환경적, 수문학적으로 영향을 미치는 것으로 조사되고 있으며 도시물순환계는 강우가 지표에 도달 한 후 바로 하천으로 유출되는 것과 침투하여 서서히 유출하는 자연경로 그리고 상수도 및 하수도를 통해 하천으로 배수되는 인공적 경로에 의해서 형성된다. 일반적으로 신도시 개발 전후의 수문순환을 평가하는 방법 중의 하나는 개발예정지에 대한 장단기의 수문 관측을 통하여 개발 전과 개발 후의 유출특성과 수질부하를 정량적으로 비교하는 것이다 (한국건설기술연구원, 2004). 따라서 본 연구에서는 행정중심 복합도시 물순환 해석을 하기 위해 대상유역을 100m 크기의 정방형 격자로 구분하고 기상조건, 지표면 조건, 하천, 토양, 지하 대수층, 농업용수 등의 광범위한 입력 자료를 구축한 후 이를 물리적인 기반의 공간분포모형인 WEP 모형에 적용하여 개발 전 홍수 및 유출특성을 규명하고자 한다. 이를 위해 대상지역에 대한 장기적인 수문모니터링 자료를 바탕으로 1996년에서 2007년 까지 모의 하여 실측자료가 있는 $2006{\sim}2007$년을 대상으로 비교한 결과 일부 갈수기 자료를 제외 하고, 전반적인 높은 상관성을 나타냈다. 하지만 일부 홍수위에서 금강으로 부터의 배수위 영향으로 인한 차이가 발생해 추가적인 검토가 필요하며, 본 연구에서 도출된 결과들은 향후 도시유역에서의 수자원 분배와 물자원 관리 등의 적응전략을 수립하는데 있어 본 연구가 도움이 될 것이라고 판단한다.

The main purpose of this paper is to analysis the growth process of new emerging Korean society in Georgia, the USA by investigating changes in the regional distribution of Korean business located in metro Atlanta region. More specifically, it aims to identify the characteristics of spatial distribution of Korean business in metro Atalanta through their locational trends since 1980s. To this end, it has explored the history of Korean migration into Georgia and the locational trends of Korean firms in metro Atlanta by industries. As a result, the main location of Korean firms has expanded into the northeastern regions of Atlanta due to the development of transportation, new regional development, education environment and changes in residential distribution by ethnic. Also, the main Korean business has transformed from retails and restaurant to real estate and finance because of changes in market strategies, institutions and Korean local migration.

Facing reconfiguration of world economic order in the process of globalization and changes in domestic economic and social conditions, Japan has experienced a rapid inflow of foreign immigrants and hence a restructuring of labor market and ethic and cultural mixture. This paper explores contexts of inflow and social and spatial characteristics of immigrant workers in Japan. Uneven regional development on the global level and shifting to flexible accumulation regime, depletion of previously underutilized labor resource, better-educated youth and shrinking and aging of Japanese populace on the national level can be pointed out as important elements of immigration contexts. This paper also explains the hierarchizaton of labor market and differentiation of spatial distribution of immigrant workers in Japan in terms of visa condition and nationality. In particular, focusing on the case of Hiroshima prefecture, this paper analyzes residential differentiation of immigrants according to their nationality. Finally, it finds out some problems which immigrant workers have confronted in Hiroshima region.

Housing market is segmented through 1) housing supply classified by housing characteristics and 2) housing demand classified by different housing opportunity of household. Moreover, neighborhood plays a role in intensifying housing market segmentation as a factor affecting on decision making relevant to housing supply and demand. while segmented housing markets have different mechanism, existing studies on residential differentiation and housing market have overlooked the characteristic differences among housing submarkets as the studies presume metropolitan housing market to be a single housing market. while the concept of 'residential differentiation' pays much attention on spatial pattern after the ecological approach appeared, the concept of ‘housing submarkets' is explanatory of the process of urban space structure formation. Analysis on housing submarkets makes up for the weak points of the behavioral approach inquiring into socio-economic constraint and different housing opportunity of household.

The creative class is the class of workers whose job is to create meaningful new forms. Recently, much attention has been focused on the role of the creative class in regional development. Many policy makers have invested to amenities to attract more creative class into their cities or regions for regional economic growth. However, there are only a few studies about the migration of the creative class in Korea. The purpose of this study is to make an analysis of the movement of the creative class by using the 17th Korean Labor & Income Panel Study. According to empirical results, the creative class are more likely to move than the non-creative class. The characteristic of creative class who moved is related to married man aged 20s and 30s without own house. Also, there is the difference between determinants of migration of the creative class and the non-creative class. It was founded that the most important determinants of migration of the creative class are housing related reasons such as home ownership and job reasons. Relationship, convenient facilities are not important factors when the creative class make a decision to move.

As foreign immigrants are rapidly increasing, how they without previous knowledge and experience adjust themselves to local circumstances where they come to live becomes a major social issue. In order to analyze their adjustment process, this paper suggests a model which consists of relationships with local environment and people on the one hand, and of geographical knowledge and imagination on the other. The analysis of questionnaire survey based on the conceptual model suggests some findings. As there are considerable differences in the extent of their local adjustment and felt difficulties among immigration types, nationalities, and dwelling regions, foreign immigrants‘ policies should be devised proper for their type and characters.

This study aims to analyze the evaluation of the residential environment on the permanent rental housing in Busan. The Permanent Rental Housing policy is one of the special measures which contribute to getting the low-income urban dwellers settled in places of their own. Unfortunately the government has focused on expanding the quantity of housing even though housing doesn't mean just a physical object but the foundation of life. So the occupants who answered the survey lived in the permanent rental housing which were constructed by Busan Metropolitan Corporation. The purpose of the study is to give suggestions which can make up for dissatisfaction and apply preference of occupants based on the results of the research. The result of this study is in following; there were few significant managerial variables determinants of residential satisfaction. And significant variables are; position of rooms and bathroom facilities in internal building characteristics, color of apartment and playground in exterior building characteristics, commuting distance and viewshaft in locational characteristics. Therefore, the government needs to use cutting edge housing technologies aimed at improvement of residential environment and achievement of affordable expense simultaneously.

This study applied the contingent valuation method (CVM) to measure the benefits from an urban liner park that will be created as part of the Gyeongin Expressway downgrade project by Inchon metropolitan city government. The Incheon city government plans to create a liner park (10.5 km) in the middle of the downgraded road to provide leisure and recreation services to residents, and plans to remove retaining walls and soundproof walls to improve the urban residential environment. Considering the characteristics of a liner park that spans several districts in Incheon city and the downgraded road that will be passed by residents of nearby cities as well as Incheon residents, the target population included residents of part of Seoul and several cities surrounding Incheon. In a CVM survey of 1,000 respondents conducted in April 2018, about 70% of the respondents perceived this project positively. About 50% of 757 respondents, excluding protest bids respondents, were willing to pay additional taxes for this project. The more the respondents favored the creation of a linear park and the more they thought that this project would improve the surrounding residential environment, the more positively they evaluated the additional tax payment. The average annual willingness to pay for this project was about 15,300 won for Incheon residents and 6,800 won for residents of Seoul metropolitan area. It is interesting to observe that residents of Seoul metropolitan area, who are not directly affected by this project, were willing to pay a considerable amount for this project.

The purpose of this study is to find the housing affordability of elderly household according to household types and housing tenure and to contribute to desirable elderly housing policies. The data from the 2010 Korea Housing Survey was used for the analysis of this study and the final sample included 6,780 elderly households. The results of this study are summarized as follows; It was found that all kinds of elderly household for housing affordability were affected by income, residence period, housing location and size of house. And housing location was a highly influential factor. Besides, female elderly house-owners and male elderly renters living alone were likely to have higher housing cost burden. And if elderly renters households suffer more financial burden, they had have higher housing cost burden. It is implies that desirable elderly housing polices by government need to consider elderly househod's diverse characteristics in aged society.

주거시설 확장 및 도심 내 인프라 구축을 위한 지속적인 산지 개발과 기후변동성 확대로 발생하는 게릴라 국지성 집중호우 등으로 인해 토석류의 발생가능성은 지속적으로 확대되고 있다.(kim et al., 2008) 그러나, 현재 국내의 토석류 방재시설에 대한 설치는 아직 미흡한 실정이며 아직 경사지 재해 발생 위험지역에는 방재시설 설치가 필요하다. 지자체의 제한된 예산으로는 필요한 모든 지역에 설치가 불가하기 때문에 순차적으로 효율적인 설치가 이루어질 필요가 있다. 이에 본 연구에서는 도심지 내 소규모 산지에 대한 효율적인 설치방안을 모색하기 위해서 방재시설 설치 이후 토석류의 거동을 수치모의를 통해 방재시설 설치의 효율성을 분석하였다. 도심지 내 위치한 토석류 발생이력이 있는 소규모 산지의 토석류의 특성을 조사한 결과, 주요 발생원인은 국지성 집중호우로 인한 지반 약화로 인해 급경사를 이루고 있는 암반층 상단에 분포한 퇴적층의 붕괴가 주요 원인으로 나타났다(Kang et al, 2014) 조사결과에 근거하여 해당 유역에 대한 토석류 발생의 유입조건을 산정하였으며 유입조건에 대해 토석류 거동 예측 2차원 해석 소프트웨어인 FLO-2D를 사용하였다. 수치모의를 수행하여 방재시설이 미설치된 상태에서 발생한 토석류의 거동을 실제 발생한 토석류와 비교하였다. 또한, 수치모의에서 방재시설의 구현이 제한되므로 4가지 방재시설(교란사면용 토석류 방지시설, 울타리형 토석류 방지시설, 토사유출 저감용 지오셀, 토석류 방재장치)에 대해 경계조건의 변경을 통해 간접적으로 구현해 결과를 분석하였다. 방재시설은 종류 및 설치위치에 따라 토석류에 대한 피해저감효과가 상이하게 나타났다. 토석류 방재장치를 토석류 발생위치 전방 50 m 지점에 토석류 방재장치를 설치한 경우, 토석류의 유속이 20% 감소하여 피해범위는 36% 감소하였으며, 전방 200 m 지점에 설치한 경우, 피해범위가 14% 감소하였다. 검토한 4가지의 토석류 방재시설 중 토석류 방재장치가 가장 효율적인 결과를 나타냈다. 향후에는 피해범위에 대한 조건 외에 시공 및 유지관리 등에 대한 경제성검토를 한다면 종합적으로 방재시설 효율성을 검토할 수 있을 것으로 본다.
