The purpose of this paper is to estimate the external diseconomies of an unwelcomed facility on the nearby houses. The facility and the area studied are Dangin-Ri power plant in Mapo-Gu, Seoul and the residential district surrounding it respectively. The nearby housing prices have been changed according to the time and circumstances of the public announcements about the reconstruction or removal plans of the plant. These price changes are regarded as the capitalized values of the external diseconomies due to the plant. This study is based on the hedonic price theory in order to estimate the diseconomies in monetary value. The tools for the estimation are four models of multiple regression with the transaction price as the dependant variable and various housing characteristics including the external effects of the plant as the independent variables. The sample analyzed is 833 house transactions for the past 5 years in the research area. The facts found are as follows; First, the most suitable functional form for the estimation is confirmed to be the linear model. Second, there are significant differences in influence on the housing values among the independent variables, that is, locational characteristics, physical features, and environmental changes with time. Third, the external diseconomy is estimated as \80,137,807 in case that the plant would be reconstructed in the underground of the present site, whereon a substitutional public park would be constructed and as \59,142,248 in case that the plant would move away.

In South Korea, problems such as low fertility, aging population, and income polarization have recently become more serious. In this time of social change, it is necessary to examine the current changes occurring to residences in order to improve the stability and health of residential areas. The purpose of this study is to investigate the changes of residential areas that occurred between 2000 and 2010 based on detached houses, which are the foundation of residential areas in Seoul. Changes in residential areas can be observed by examining changes in the type of housing and the characteristics of the residents. Since the type of housing and the characteristics of the residents change in the same area, it is necessary to study them together, not as individual elements. Census data is suitable for this purpose, because it can show the changes that have occurred to the housing type and the residents' characteristics within the neighborhood unit. Among the census output areas identified as residential areas based on detached houses, six sites were selected as the case study area based on the rate of change of detached houses. From the result of the case study using the census data, the study area was categorized into three regional types: (i) an urban development and redevelopment area; (ii) an area with a concentration or increasing number of detached houses; (iii) an area with an increasing number of multi-family houses based on detached houses.

This study aims to propose a hypothetical urban neighborhood, HanGyo-dong, which is a model for understanding the relationship between the neighborhood change and educational facilities. Three issue layers of the model derived from preceding case studies are: establishment, relocation and redevelopment of educational facilities; formation and redevelopment of adjacent residential areas; and growth of neighborhood commercial cores. The neighborhood changes observed through HanGyo-dong include (1) the formation of educational base and commercial activities along the stream, (2) the growth of student and intellectual community and the installment of public transportation nodes, and (3) the relocation of schools and hospitals followed by a series of redevelopments of single family house into multi-family housing of low-rise residence and high rise apartment complex. The findings call for the collaborative practice of educational administration and neighborhood planning regarding how educational facilities, which were the tool for urban expansion policy, will contribute to the development of the neighborhood's identity as a localized hub.

This study aims to investigate how easy pedestrians get around within/through the "Apartment Complexes (AC), " a common style of high-rise multi-family housing in Korea. Over the past six decades, the AC has been the most conventional way to provide standardized housing efficiently to address the problems of the shortage of housing and the substandard housing, due to the explosion of urban population with the rapid industrialization. The AC is a huge chunk of homeogenous multi-family housing, mostly condos with decent infrastructure, including parks, pedestrian passages, schools, ect. Both in the new town development and urban renewal programs have utilized the advantages of the AC. Since the design principals of AC tend to adopt the "protective design" to prevent cars and pedestrians coming outside from passing it, it has been criticised for dissecting the continuity of socioeconomic context in neighborhoods. The neo-traditional planning urbanists, including Jane Jacobs, emphasize that smaller blocks and grid road newtworks are the key in improving social, cultural, and economic vitality of the neighborhoods, because these design concepts allow more pedestrians and different types of people to be mixed in a neighborhood. In this study, we first adopted objective measures for pedestrian accessibility and pedestrian efficiency. These measures were used to calculate the lengths of shortest paths from residential buildings to the edges of AC. We tested the difference in shortest paths between the current pedestrian networks of AC and hypothetical grid networks on the AC, and the relative difference is considered as the pedestrian efficiency, using the network analysis function of Geographic Information Systems (GIS) and Python programming. We found from the randomly selected 30 ACs that the existing non-grid road networks in ACs are worse than the hypothesized grid networks, in terms of pedestrian efficiency. In average, pedestrians in AC with the conventional road networks have to walk than 25%, 26%, and 27% longer than the networks of $125{\times}45m$, $100{\times}45m$, and $75{\times}45m$, respectively. With the t-test analysis, we found the pedestrian efficiency of AC with the conventional network is lower than grid-networks. Many new urbanists stress, easiness of walking is one of the most import elements for community building and social bonds. With the findings from the objective measures of pedestrian accessibility and efficiency, the AC would have limitations to attract people outside into the AC itself, which would increase dis-connectivity with adjacent areas.

A planned access method on constantly-changing-community unit plan changes and develops based on the periodical situation and also plan theory. In this research, it is to present the link between the theory of complex city change and the plan factor of it, and to show how Korean residential complex plan has changed as time passed and how new concept of city plan came up and by applying new methods how can this affect our real world and the past plan. In the phase of analysis, it analyzed the flow of 'community unit plan' and its theory and investigated the factor of compositional space and built a analysis frame. The factors of community unit plan are space structure, size and shape of block, population, distribution of facilities and movement system. It chose the place that can represent the flow of community unit plan trand and that indicates the obvious development leading to Jamsil (1975), Gwa Chun (1980), Mok Dong (1983), Sang Ge (1985), Ilsan (1989), Dong tan (2001) and Eun Jung (2003) total of 7 places. And to compare a similar size of the city, it selected a small community unit. Based on the result of theoretical study and prior research, it can be said that the space composition style has change from a whole complete complex area to a linked-cross over community unit and the access of urban level was on set. Also, a pedestrian walking area was secured and the dense of building structure and pleasant environment wanting need was in balance. For facility plans, the usage of facility and functional change brought change of type, size and disposition. The walking area for pedestrian became a huge matter. Therefore, market, education, public facilities and green system collaborated to co-build a whole community unit and activated the walking environment. Also, public transportation, environment friendly city organization was built.

본 연구는 청년층 가구의 주거실태 변화를 종단적으로 분석하고 이를 전국 가구와 비교하고자 한국복지패널(Korea Welfare Panel Study, KoWePS) 5차 웨이브(2010년)와 15차 웨이브(2020년)을 활용하였다. 분석 결과를 요약하면, 청년층 가구 수는 조사 기간 중 절반 수준으로 급감하였고, 청년층 가구의 가구주는 주로 대졸 이상의 고학력 30대 초반 기혼한 남성 임금근로자였다. 10년 간 고학력자와 임금근로자의 비율이 크게 늘어나면서 소득도 향상되었으나 여성 가구주와 미혼 1인 가구의 증가가 두드러지면서 전국 평균 소득과의 격차가 줄어들었다. 청년층 가구는 대체로 비수도권 지역에 거주하였고, 침실 2실을 갖춘 중형 공동주택의 임차인이었다. 특히 아파트 외 공동주택에서 월세로 거주하는 가구 비율이 높아지면서 주거비 부담은 전국 평균을 웃돌았고, 주거비를 25% 이상 부담하는 가구의 증가율이 전국 평균보다 높았다. 다만 청년층 가구의 수도권 거주 비율이 전국 평균을 상회하고, 조사 기간 동안 전국 가구에서 월세 거주 가구가 차지하는 비율에 변화가 없는 것과 달리 청년층 월세 가구 비율이 현저히 상승함에 따라 실제 청년층 차가 가구의 실질적인 주거비 부담은 더욱 커졌다. 또한 전국 평균을 밑도는 청년층 자가 비율과 함께 조사 기간 중 전국 자가 비율의 플러스 성장과 달리 마이너스 성장률을 보인 청년층 자가율의 변화폭은 주거사다리의 진입이 어려워진 청년층 가구에게 비우호적인 주택시장 여건을 보여준다. 따라서 청년층 친화적인 주택시장 여건 조성을 위한 시책들이 마련되어야 할 것이다.

The goal of this research is to explore quantitative and residential features and spatial patterns of two-person households to suggest policy implications for housing supply and development in Seoul. Major findings of this study are as follows. First, the number of two-person households has increased rapidly mainly due to the growth of the elderly and single-parent households. They are mainly composed of the elderly over 60s and the youth of 30s of householder age. They are less likely to have well-paying jobs, and thus more likely to suffer from poverty. They are also inclined to live in rental and small-sized residential units and spatial segregation between the youth and the elderly became serious. In addition, their residential area can be classified into four types: area adjacent to employment centers, hinterland of urban centers, affordable multi-family housing area and redeveloped apartment area. It is necessary to change the current housing policy directions to take changing population and household structure into consideration. Also, diversified housing strategies and programs should be prepared to consider various household types and their needs and demands. Place-based strategies for housing supply and development are needed in consideration of spatial patterns and locational attributes of two-person households. Attention needs to be paid to resolving the social issue of residential segregation between different generations.

This is a case study of private sector's development of long-term unexecuted urban parks in Pohang through a special act, which provides a guideline of 30% of land for non-park while 70% of land for park. The strategy has a lot of validity in many respects along with the urban planning sunset system, but even with the special act it would not easy to be implemented in Pohang, where the guideline has been modified to 20% for non-park, mostly multi-family housing projects while 80% for park. Thus, participation of private companies would be discouraged due to low commercial validity. Also, there would exist various risks because the project would be completed through a long-term decision-making and execution process. Thus, this study argues that it would be better for Pohang to follow the original guideline of the government for better implementation of the projects, along with preparation of a law with which the government be able to recoup excess profits when too much profits would be given to private developers. For the project implemented smoothly, it is also important to understand local housing market and fluctuating economic conditions, and to prepare various incentives for private companies. In addition, to secure publicity, guidelines on the level of publicity of the project should be prepared through negotiation by parties to prevent the project being discouraged too much.
