With the rapid changes in healthcare system, the impact on healthcare design is significant and constantly changed. Because of emergence of new technology, far-advanced methods of healthcare delivery, and changing social and environmental issues, the healthcare planners and architects have to make sure that future expansion are taken into consideration when they design the hospitals. This thesis aims to investigate the hospital remodeling cases in Korea and USA and find the solutions for the vertical expansion of the hospitals in the metropolitan area where the buildings may be limited to be horizontally expanded. The M Cancer center in Manhattan, NY is selected to be carefully investigated and analyzed. Based on this analysis, the strategy for the vertical expansion of the hospital will be suggested.

The aim of this paper is to define major factors influencing land development of each of major uses (residential, commercial, industrial) in the process of rapid urban expansion. The main hypothesis of this study is that land use changing patterns are directed by supply side of land managed to public policies rather than demand side. The graphic analysis is applied to relationships between urban growth and land development process of each use and between land development project managed to public policies and land development process. Public and land development projects and zonning protection seem to be major roles of land supply and main determinants of urban spatial structure. Location factors for land development of each uses are selected in 23 variables. Factor analysis is applied to test correlation between variables in 1971 and 1981. Factor structure between two years is similar, but progressive processing of functional separation is derived such as intensive land use is grouped, different location between residential and industrial use is deep. Dependent variables are standardized to logarithm of land development of each use per unit vacant land in two periods, between 1971 and 1980 year and between 1981 year. Correlation analysis between 6 dependent variables and 23 location factors in each years are applied. Major factors of each use are selected in criteria such as high correlation with dependent variables, low correlation between independent variables and common application in two periods. As the result, major factors for residential land development are Land Readjustment Project (LRP), percent of total zoned area in residential zone, residential floor space density per available area, percent of total area in industrial use; for commercial development is distance to CBD, percent of total area in commercial use, residential floor space density per available area in each year, and volumn rate of industrial use; for industrial use is percent of total area of industrial use is percent of total area of industrial use, Industrial Estate Project (IES), LRP, and distance from CBD. Land development pattern of each use between two periods are slightly different. So 6 equation is derived from appling backward method of regession. Adjusted multiple R squares of all is more than 0.5 and those equation is statistically significant and valuable to assist urban land use forecasting.

The goal of this study is to examine municipality comprehensive plans by recognizing the problem that adverse impacts of urban regeneration impede the sustainability of specific renewal project. 10 major cities in Korea that are experiencing urban decline were chosen for the study area and plan evaluation indexes were adopted based on the sustainable urban regeneration principles in terms of environmental, social, and economic aspects. Plan evaluation was conducted by employing the content analysis method and developed assessment indexes for three sectors (factual basis, goal/objective, and policy/action) of plan. The findings show that policies, such as 'expansion of parks in urban area,' 'pedestrian-oriented street improvement project,' and 'countermeasures for local industry revitalization,' should be fundamentally included in adopting sustainable urban regeneration plans. Plan scores regarding sustainable urban regeneration had an insignificant relationship with the status of administrative district and plan adopted year. This is because metropolitan municipalities, including Ulsan, Daejeon, and Daegu, received relatively low plan score compared to local governments like Goyang and Suwon. Also, Daegu and Suwon, which established their comprehensive plan in 2018 obtained lower score than Seoul and Incheon, where its plans were created before 2015. Evaluation protocol and indexes that were suggested in this study can be used while reorganizing each locality's comprehensive plan, and thus, play as one of major bases in preparing future sustainable urban regeneration projects.

Low-rise Residential neighborhoods of Hongdae area, Garosu-gil, Samchung-dong, Itawon etc. are currently emerging new spaces for cultural consumption in the city. Nonetheless undiscerning excessive commercialization often results in monotonous urban space and deportation of residents and leaders of change; Due to commercialization and popularization recently this phenomenon is influencing surrounding low-rise residential neighborhoods. The main objective of this study is to examine how surrounding low-rise residential neighborhood transforms according to the expansion of culture-commerce spaces. Hongdae area's culture-commerce spaces and its expansion into Yeonnam-dong is investigated in specific. Especially attributes and main causes of transformation in physical and experiential space of neighborhood living facilities and residential buildings, when changed into culture-commerce related use is examined in detail. The expansion of culture-commerce space of Hongdae to Yeonnam-dong area has positive meaning in aspects of everyday experience. First, physical alteration of street-building relation increases direct and indirect contact of people. Contact opportunity carries important meaning in sense that it is prerequisite for next stage contact of network and exchange. Second, culture-commerce related programs provide the third place, where various leisure activities can take place. Attributes of transformation and positive meaning of culture-commerce spaces expanding its territory presents the need of management.

The purpose of this study is to present the rational decision process for new ward office building site. AHP Technique used in this study considers both quantitative and qualitative factors on the basis of decision maker's intuitive, reasonable or unreasonable judgement by giving weight through mutual comparision of publicity factors. The evaluaion factors were refer to another five ward office there were executed these kinds of new site selection before. These standards are composed of 6 middle groups and classified into 9 detailed standards. Alternative building sites are five places in this district. The final evauation standards are Accessibility, Urban Expansion Possibility. Distrct balance, Environment, Financing. Development easiness. And It became clear that the priority of evaluation is Financing > Urban expansion > Accessibility > Development easiness > District balance > Environment. In conclusion, it was determined that alternative " E " is the most adequate place for new ward office building.

The nonlocal static bending, buckling, free and forced vibrations of graphene nanosheets are examined based on the Kirchhoff plate theory and Taylor expansion approach. The nonlocal nanoplate model incorporates the length scale parameter which can capture the small scale effect. The governing equations are derived using Hamilton's principle and the Navier-type solution is developed for simply-supported graphene nanosheets. The analytical results are proposed for deflection, natural frequency, amplitude of forced vibration and buckling load. Moreover, the effects of nonlocal parameter, half wave number and three-dimensional sizes on the static, dynamic and stability responses of the graphene nanosheets are discussed. Some illustrative examples are also addressed to verify the present model, methodology and solution. The results show that the new nanoplate model produces larger deflection, smaller circular frequencies, amplitude and buckling load compared with the classical model.

We present an analysis of urban development and growth with reconnaissance satellite photographs of Columbus metropolitan area acquired by the Corona program in 1965. A two-dimensional polynomial linear transformation was used to rectify the photos against United State Geological Survey (USGS) Large-scale Digital Line Graph (DLG) data georeferenced to Universal Transverse Mercator (UTM) coordinates. The boundaries of the Columbus metropolitan area were extracted from the rectified Corona image mosaic using a Bayesian approach to image segmentation. The inferred 1965 urban boundaries were compared with 1976 USGS Land Use and Land Cover (LULC) data and boundaries derived from 1988 and 1994 Landsat TM images. The urban area in and around Columbus approximately doubled from 1965 to 1994 (${\sim}110%$) along with population growth from 1960 to 1998 (${\sim}50%$). Most of the urban expansion results from development of residential units.

The authors derived rental housing policy measures that are appropriate for the current conditions of Korean housing supply and demand based on the confirmation of the issues of Korean rental housing system and reviewing implications from review of cases of foreign countries and these measures can be categorized into linkage with the urban regeneration and multi-functional development, acquisition of financial resources, operational management, policy and institutional aspects. For the expansion of supply of rental housing, it is essential to link the rental housing policy with urban regeneration. To pursue regeneration of underdeveloped areas and expansion of supply of rental housing in line with urban regeneration, more development sites should be added. Further, the rental home policy must be integrated into a new paradigm that includes securing commercial viability and providing various residential conveniences through multi-functional development. In addition, diversification of developers of real estates turning away from the existing framework of policy that has been focused only on the state-led housing supply so that local governments and private sector players can take part in. Next, new options for funding the supply of rental housing must be sought. First, raising financial resources sequentially through cyclical development approach could be considered. Or, various funding schemes including utilizing Tax-increment financing (TIF) based on the local tax revenues that will be accrued after the development projects and supply of rental housing. Or there should be various schemes to raise funds including utilization of TIFs that are based on the revenues that will be realized after the development projects and supply of rental housing, or utilizing REITs where funds can be provided through private sector investments. Also, getting out from the planning practice that focused only on physical expansion of supply of rental housing, continual operational management must be performed even after the development. These activities must be supported through establishment of control tower at the national level and continuous attention must be paid even after the development by developing specialized operational management companies that are led by private sector players. Finally, in addition to the hardware support that is focused on the public rental housing only, software support such as conditional provision of housing voucher or tax exemption for low-income classes should be provided, too. In other words, a shift from policies that are supplier-centric to ones that are customer-centric must take place.
