The primary goal of this research is to link two currently disconnected literature; the history of urban redevelopment and the one of urban parks and open spaces in the United States (US). Through this exercise, this study attempts to reveal examples of urban parks and open spaces that have yielded economic effects, and emphasize their possibility as a measure of urban redevelopment. Five phases are presented, starting with two Pre-World War II urbanization periods, and three subsequent periods of Post-World War II urban redevelopment (1940s~1960s, late 1960s~1970s, 1980s~present). While urban parks in the 19th century urbanization period held a preeminent place in urban design, policy and economy, ensuing depression and World War II diminished their role as a channel to ease unemployment. In the first phase of urban redevelopment, the economic motive to build open space was to boost the appeal of specific locales in order to draw people and businesses back to a neglected city. In the second phase, public effort to create and maintain urban parks and open spaces declined due to the budget austerity, instead, community open spaces flourished through the voluntary actions and helped neighborhoods to regain desirability. In the third phase, the aspirations and functions of such projects resemble their forerunners of the first phase, but their targets extended to global businesses and elites.

Landscape urbanism emerges as an alternative to the urban design theories of the past century, emphasizing landscape as an organizing principle, integrating the medium of different elements of the urban environment. However, ongoing criticism of the theory's lack of consideration for physical urban morphology has not supported the integrity of the theory. Large parks, which many proponents of the theory have referred to, possess valuable and interesting points in their design and management. This also shows the limitation of not being able to show the close physical relationship between open space and the city. In this study, the High Line project was analyzed to verify it as founded on landscape urbanism, providing that landscape urbanism drives the urban morphology on a small scale rather than a large one. This paper concludes that landscape urbanism should include small parks as one kind of study model with the small grained interaction between open spaces and the cities under this category to broaden and deepen the perspective. Also, the effort to analyze quantified and physical consequences of the theory through close observation should be followed to extract the design strategies to be applied to future projects.

이 연구는 뉴욕 하이라인의 부동산 가격 상승 영향 분석을 통해, 어메니티 고급화 전략이 부동산 시장 활성화를 유도할 수 있는지에 대한 해답을 모색함을 목적으로 한다. 먼저 Random-slope multilevel modeling (다층모형)을 이용하여 하이라인 전, 후 기간의 부동산 가격영향을 각기 분석한 뒤, 이를 이용해 재산세를 산출하여 비용 편익을 검토 하였다. 준공 후 하이라인에 의한 부동산 가격 상승 정도는 Census tract (인구 조사 표준 지역)에 따라 다르나, 100ft 접근당 최고 1.16% 으로 추산되며, 이는 준공 전 상황과 비교할 때 상당히 증가한 것이다. 이를 통해 환산한 재산세 증가는 2012년 기준, 매해 미화 천팔백만 달러, 향후 20년간 이억 오천팔백만 달러가 회수될 것으로 예측되며, 이는 당초의 공사와 관리비를 상회한다. 그러나 이러한 경제적 가능성에도 불구하고, 유사한 전략을 전개하기에 앞서서는 경제적 영향 외애 사회적 영향, 그리고 적용가능성 분석이 선행되어야 한다.

This study aimed to investigate the impact of the quality of the street environment in residential areas on the mental health of urban residents, considering the frequency of street use. Using a zero-inflated negative binomial regression model, the study analyzed the influence of walking frequency and the street environment on depressive symptoms of urban residents. The research focused on Seoul, South Korea, in 2017, with depressive symptoms as the dependent variable and street environment variables, walking variables, and individual characteristics as independent variables. Additionally, the study explores the interaction effect of street greenery and walking frequency to analyze the synergistic impacts of walking in green spaces on mental health. The findings indicate that a higher ratio of street green areas is associated with fewer depressive symptoms. Increased walking frequency is linked to a reduction in depressive symptoms or a weaker manifestation of such symptoms. The interaction effect confirms that more frequent walking in green spaces is associated with weaker depressive symptoms. Lower ratios of visual complexity are correlated with reduced depressive symptoms. This study contributes to addressing urban residents' mental health issues at the community level by emphasizing the importance of the street green environment in residential areas.

In this study, we aim to compare food establishments a major retail district(bal-dal retail area) and its extended area(gol-mok retail area) in Itaewon from 2001 to 2006. First, using Kernel density estimation, we delineate the boundary of those two areas, and second, using Kaplan-Meier method and Cox"s proportional hazards regression, we empirically analyzed differences of survival rates and factors(locational characteristics & restaurants characteristics) influencing hazards of restaurants in each retail district. As a result of Kaplan-Meier modeling, extended area(median survival time 2,304 days)has faced a higher risk of closing their business than their counterpart major retail district(median survival time 2,748 days). However, Cox"s proportional hazards model, with controlling various factors influencing the business operation, suggests the opposite that the extended trade area has been an advantageous location, as the hazard of closing business is lower by -29.9% than the one of the major retail district. Variables being franchise is common variable to impact the survival time in each retail district. On the other hand, variables such as reach, straightness, on the 1st floor(major) and distance to subway & main road, parcel slope(extended) are more likely to impact the survival time at each area. Based on findings of this study, we conclude that failure patterns of those two retail areas are not identical and different strategies should be utilized for risk-management using the aforementioned factors.

Street gardens, a series of streetscape improvement projects led by Seoul City Government, are initiated for the purpose of providing aesthetic satisfaction and mental refreshment to pedestrians. In order to investigate whether street gardens indeed promote the psychological health of the users, questionnaire surveys were conducted on three selected street gardens - at Gangnam-daero, Digital-ro, and Teheranro - and their comparison sites located on the same streets, which have a similar physical environment but without a street garden. The survey questionnaires, based on Attention Restoration Theory, were composed of Perceived Restorativeness Scale-11 with the eleven individual questions grouped into four categories: 'Fascination', 'Being away', 'Coherence', and 'Scope'. The survey questionnaires also ask about physical components that promote psychological improvement in the aforementioned categories. The collected data was analyzed with factor analysis, reliability analysis, and independent t-test. The results suggested that street gardens had a relatively positive effect on the psychological restorativeness of the users. In particular, they gave fascination and interest to the users. However, they did not offer a feeling of being away to the users, which revealed the limitation in the psychological improvement effect of street gardens. The physical components of the street garden that have led the psychological restorativeness effect were wooden bench, tree, and flower. This result corresponds to an extant theory that natural factors have a positive effect on the psychological restorativeness within a hardscape. This research will shed light on the planning and design guidelines for the street garden project.

In this study, we aim to analyze price impacts of a Newtown project on nearby housing markets in Changsin·Sungin Newtown in Seoul, Korea. Newtown project launched by Seoul Metropolitan Government in 2002, is a neighborhood redevelopment program addressing both housing shortage and deteriorating infrastructure. Using hierarchical linear modeling structured by transaction time, with monthly housing transaction data from January 2006 to April 2016, we investigate the effects of a Newtown project on housing prices within and outside of its boundary along the process of designation to withdrawal. In general, we found a positive influence of Newtown within area. In case of multi-family housing and apartment, the market transaction property value is higher by, on average, 12.2% and 16.6% respectively within the Newtown boundary, and –10.9% and 3.3% in the within-500m boundary, and –7% and –4.6% in the within-100m boundary compared to the specified control group. In transaction-time specific analysis of the effect, we found that the average price of multi-family housing within the Newtown boundary were higher by 30-40% than their counterparts before the Newtown designation, but fell down from that point, then the premium becomes negligible toward the withdrawal. On the other hand, in the 500m boundary we found that average price of multi-family housing were lower by 14-18%, but it rose up from the start(2006.1) to withdrawal. In case of apartment housing the prices were higher by 5-10% within the Newtown boundary. It also slightly fell down at the announcement of the designation by 10-20% in the 500m boundary(<500m, within 500m zone, excluding the Newtown) and 100m boundary(<1000m, within 1000m zone, excluding the 500m zone).

This study investigates the effect of a landslide disaster - Mt. Umyeon landslide, Seoul, Korea in July, 2011 - on apartment market values. We adopt two analytical methods – a random intercept modeling (Analysis1: the geographic extent of disaster impact) and a piecewise linear random coefficient modeling (Analysis2: the temporal extent of disaster impact). Particularly the latter method enables examining transforming price impacts of the disaster based on a series of piecewise estimations over each time segment. The results suggest that the discount effect of the landslide is observed within 500 meters from Mt. Umyeon, evidenced by 15.5% and 14.3% price drop occurring within 250 meters and 500 meters range respectively. The results also suggest that the effect has last for a year after the disaster, in that during the first six months, the apartment value was decreased by 2.8% per month, and then increased by 3.3% per month for the following six months, compared to their counterparts, holding all other conditions constant. By revealing home-buyers’ perception on natural hazard, this research will be a valuable reference in establishing the disaster mitigation plan and the corresponding insurance policies.
