Social costs analysis seeks to reveal the environmental effects of transportation policy. It delivers a sense of the effects of the public's daily travel and the costs that are or would be incurred from individual trips. Moreover, the accumulated total number of trips will uncover the effects of travel on society. This article shows the quantitative analysis of the economic outcomes of travel using social costs estimation methods. In order to support urban planning tasks, this research implemented analysis tool for social costs estimation by travel behavior. For a case study, a jave based application which can convert people's trip data into social costs is developed. the application used for simulating student-housing effects by estimating social costs changes. The analysis included the attributes, building scale and locational changes of the student housing as well as transforms of the students' trips.

Aedes albopictus, a common species in the Republic of Korea, is internationally known as a major vector for various diseases, and it is well-adapted to urban environments. Recent insect outbreaks in urban areas, attributed to climate change and urban heat islands, have increased the necessity of researching the effects on mosquito populations. This study analyzed climate data from 25 Automatic Weather System (AWS) stations in Seoul, identifying urban areas with pronounced heat island effects and suburban areas with milder effects. Nine urban heat island conditions were established based on this analysis, under which the hatching rates of Ae. albopictus were examined. The results revealed an increase in hatching rates correlating with the intensity of the urban heat island effect. Regression analysis further indicated that this trend accelerates as the strength of the heat island effect increases. This study suggests that temperature variations resulting from urban heat island phenomena can significantly influence the hatching rates of Ae. albopictus.

PURPOSE: Social participation is essential for stroke survivors. Although participation restrictions are affected by several factors, a few studies have focused on the effects of living in a particular residential area (urban versus rural) on the participation restrictions after a stroke. This study examined the factors affecting participation restrictions in stroke survivors according to the residential area. METHODS: One hundred sixty-six stroke patients (including 130 living in urban areas and 36 living in rural areas) were recruited for this study. The Korean Modified Barthel Index (K-MBI) was used to assess the activities of daily living (ADL). The Korean Mini-Mental Examination Status (MMSE-K) was used to assess cognition. The motor function was evaluated using the Fugl-Meyer function assessment (FMA). Path analysis was used to test the hypothesized model of participation restriction. RESULTS: The proposed path model showed good fit indices. In rural and urban areas, the direct effects were significant between the ADL and participation restrictions (β = -.673 and -.457, respectively). For urban areas, the direct effects were significant between cognition and participation restrictions (β = -.252). In both area types, motor function and cognition had a significant direct effect on the ADL. CONCLUSION: For urban community-dwelling stroke survivors, the ADL and cognition had direct effects on participation restrictions. For rural area stroke survivors, the ADL had direct effects on participation restrictions. Activity level exercise programs help reduce the participation restrictions. Moreover, it is essential to address cognition training to improve participation in urban community-dwelling stroke survivors.

The study on urban regeneration began in 2006 and has actively proceeded for 10 years. Also, there are a lot of studies related to urban regeneration have analyzed urban regeneration effects but have just focused on qualitative analysis. Therefore, this study has intended to analyze the urban regeneration effects of Junang-Dong, a central business district in Cheong City, where urban regeneration projects have been undertaking, in the manner of quantitative analysis. To reach this objective, we selected such indicators as floating population, public land price, a and vacancy rate, and set analysis time span from 2011 to 2016, when urban regeneration projects have been actively operated. As a result, this study has found the following results. 1) As for floating population, population index grew gradually and showed an drastic increase of about 65 percent in 2014 when the project was active. 2) Public land price of Jungang-Dong has been showed the greatest increase from 2011 to 2012 when the city started to regenerate, and slight decrease from 2015 to 2016 with the gradual decrease until 2015. 3) In terms of vacancy rate, there has been declined about 15 percent from 27 percent to 12 percent, with a steady downward curve. This study has dedicated itself to analyzing the urban regeneration effects quantitatively especially in commercial business district.

In this study, Urban Climate Simulation was performed using 3-Dimensional Urban Canopy Model. The characteristics of urban thermal environment was analyzed by classifying land coverage and increasing natural land coverage ratio. The results are as follows. The characteristics of the land coverage on urban thermal environment formation can be summarized by the effects like higher temperature on the artificial coverage, and the contrary effects on the natural coverage. When the water coverage 100% was made up, maximum temperature was declined by $5.5^{\circ}C$, humidity by the 6.5g/kg, wind velocity by 0.6m/s, convective sensible heat by $400W/m^2$ and the evaporative latent heat was increased by $370W/m^2$ compared to when artificial coverage 100% was formed. These simulation results need to be constructed as DB which shows urban quantitative thermal characters by the urban physical structure. These can be quantitative base for suggesting combinations of the building and urban planning features at the point of the desirable urban thermal environment as well as analysing urban climate phenomenon.

Purpose - This research examines the effects of local universities on urban regeneration to recover commercial supremacy in the original urban area and provides clear information on the "University Cooperation Project for Traditional Market." Research design, data, and methodology - The "University Cooperation Project for Traditional Market" started in 2015. This study was conducted focusing on 22 places selected in 2015 and the project content in those locations. Results - This study analyzes the link to urban regeneration and spreads the concept along with theoretical consideration of university cooperation for traditional markets. Additionally, it promotes policies to help propel the project based on characteristics of the region. Conclusions - A differentiated project should be created, with characteristics of the region reflected, and detailed programs developed and implemented resulting in meaningful achievement from the perspective of members of the local community, who may have deviated from existing perspectives. Additionally, opportunities should be established for the direct application of young consumer ideas through experimental business to regenerate the traditional market (commercial supremacy), the center of the local economic society.

The overall aim of this study is to mitigate urban environmental problems. In particular, to reduce the effects of urban heat island phenomenon which is one of the urban planning perspective. This study focused on the analysis of the relationship between the urban heat island effect and the thermal and wind properties. To do this analysis, water space was virtually made at Yeol_Mae village Apt. Because it is very difficult to set up water space for the existing apartment complexes due to realistic constraints. This study, therefore has a strong sort of guidelines to create water space for newly formed city. It was based on the concept of virtual city through an in-depth analysis on reduction of urban heat island effects for the existing apartment along with creation of water space. To analysis site, Envi-Met Model developed by Michael Bruse was used. The results are as follows. The temperature went from 298.9K to 297.82K and The wind speed went from 1.42m/s to 1.43m/s. The results are slight in this study because creation of water space is planned to a small area of an apartment complex. But if the water space would be applied to a whole city, the mitigation effect of urban heat island would be bigger.

Land price is a kind of text to read urban spatial structure. The purpose of this paper is to inquire into the characteristics of Daegu's urban structure and its change in time through exploring spatio-temporal variations of land price with a detailed spatial and temporal resolution. To achieve this, land value surfaces were represented using the officially assessed land price every other year from 1995 to 2011. Through mapping and exploring spatio-temporal patterns and fluctuation rates of land price for this period, changes in urban structure, the effects of local decision makings such as Greenbelt adjustment, housing site development, and gentrification, and the effects of business fluctuations or policies at global or national scales could be caught. In addition, the trends for suburbanization and multi-centric urban form could be examined from the results of a negative exponential model explaining the effect of distance from an urban center on spatial variation of land price. These results demonstrate that urban analysis using land price mirroring spatial decision making at various scales could deepen understanding for internal structure and change of a city and provide useful information for establishing regional and urban development policies and evaluating their effects.
