The stage for Tadao Ando's architectural works is not only in Japan but extends to many countries around the world. His creations are not limited to the world of architecture, but are widely acclaimed supported by public people as well. Why Tadao Ando's works are acknowledged and acclaimed so extensively? Japanese traditional elements used in the his works makes it so. Tadao Ando argued intuition and insanity which were deprived by modernism could recover with locality and it's historic elements laid importance to the self. To realize that, it is necessary the regeneration of landscape which was based on the site and self-reflection must accomplished with the nature. So as to regeneration of landscape, he used Japanese Landscape-gardening and make the nature condensed. With the su-ki, he made the architectural elements simple. And with the Japanese detoured circulation, he made deep and various space. In that way, he intended the nature which is changed with his idea experienced the way of yu-gen.

Strut-and-tie model (STM) has been recommended by many codes and standards as a rational model for discontinuity regions in structural members. STM has been adopted in ACI building code for analysis of reinforced concrete (RC) deep beams since 2002. However, STM recommended by ACI 318-11 is only applicable for analysis of ordinary RC deep beams. This paper aims to develop the STM for CFRP strengthened RC deep beams through the strut effectiveness factor recommended by ACI 318-11. Two sets of RC deep beams were cast and tested in this research. Each set consisted of six simply-supported specimens loaded in four-point bending. The first set had no CFRP strengthening while the second was strengthened by means of CFRP sheets using two-side wet lay-up system. Each set consisted of six RC deep beams with shear span to effective depth ratio of 0.75, 1.00, 1.25, 1.50, 1.75, and 2.00.The value of strut effectiveness factor recommended by ACI 318-11 is modified using a proposed empirical relationship in this research. The empirical relationship is established based on shear span to effective depth ratio.

The purpose of this paper is estimating environmental carving capacity of Seoul Metropolitan Area for a sustainable city management using system dynamics model. A sustainable development requires a society to define sustainability constraints or environmental limits, environmental carving capacity. Environmental carving capacity can be defined as the level of human activity which a region can sustain at an acceptable quality of life level. This concept of environmental carving capacity has several important application to sustainable city planning and management. If the limitation of a human activity can be supported by a scientific data on carving capacity, the resulting decision and actions could more easily win public support for a sustainable development. However, one of the key issues is how to operationalize the carving capacity. In this paper, the environmental carving capacity was operationalized as a maximum number of industry structure, population, and housing that can sustain certain level of environmental quality of Seoul Metropolitan Area. The model developed in this paper consisted off sectors: population, housing, industry, land, and environmental sector. The model limits its main focus on the NO$_2$level of ambient air of Seoul. Carving capacity Seoul Metropolitan Area was estimated by figuring out the maximum number of population, industry structure, housing at an equilibrium point that sustain a desirable NO$_2$level. Based on the model estimation, several policy implications for a sustainable city management was discussed.

This study identifies the common problems faced by the owners of strata titles, the Management Corporation, the Joint Management Body, the Commissioner of Building (COB) as well as the Managing Agent being the stakeholders in managing strata properties. The methods employed are qualitative in nature. Analysis is done based on reports published by the relevant authorities dealing with strata residential properties as well as the case law as reported in the two leading journals in Malaysia such as the Malayan Law Journal and the Current Law Journal. The types and nature of problems are derived from the annual reports. The extent of the problems is determined based on the figures and supported by observation and interviews with the COB, being the agency directly involved in overseeing and monitoring strata properties management. The findings show that a substantial number of problems exist in the management of strata properties despite a law that allows the owners to self-managed their own properties. Having stated the status quo concerning the problems, the study also looks at the various means of resolving disputes as exist under the Malaysian housing system. The study proposes that alternative dispute resolution (ADR) modes are more appropriate in ensuring the sustainability of strata living and management.

This paper described the characteristic of vibration in wind turbine system including gearbox housing, gear drive, blade, generator. Especially, in planetary gear set, planet gears are supported by flexible pin. So, in planet gear, to consider not only torsional movement but also lateral movement. And include housing movement, because wind turbine system is supported by mount. To find out the characteristic of vibration, take the excitation source and study campbell diagram in operating range. Results of campbell diagram, resonances are occurred at 81.2HZ, 104.7Hz by 2nd tooth passing frequency. And resonance are also occurred at 264.5HZ, 377Hz, 424.6Hz by 3th tooth passing frequency. From the result, take vibration reduced measures.

Residential environment is not only the physical aspects affected by the unique characteristics of the residents, social, economic, cultural, etc. are closely related to many environmental factors. This research is based on choice attribute theory that substantially explains how housing choice attributes affect loyalty via image, perceived value in Secho. This paper investigate empirically relationship between selection properties of residential environment and loyalty, moderating effect of image and perceived value. Results were computed using SPSS 20.0 statistical analysis programs. The results are summarized as follows. First, The elements of choice attribute are divided into six factor, such as regional reputation, green environment, convenience, property value, safety, housing status. In the results of the analyses, housing choice properties gives a positive influence to the loyalty. Second, testing its mediating role, I use the three regression equation models by Baron and Kenny. When the mediator effect of image, perceived value was represented, the effect of image and perceived value was statistically significant. Thus, the mediating role of image and perceived value was supported. It means the higher image and perceived value can enhance loyalty of Secho.

With the passing of Special Act on Promotion and Support for Urban Regeneration (will be hereafter referred to as the Urban Regeneration Special Act) in December 2013, urban regeneration projects have begun in full scale. 13 regions including Jongno District, Seoul were selected as the urban regeneration leading area in 2014 and 33 regions as urban regeneration general regions in 2015 to push ahead a nationwide urban regeneration front supported by government funds. However, it is not clear if these urban regeneration projects will be revitalized by the sole means of government's financial support. Above all, cooperation among all interested parties including the central government that is propelling urban regeneration, local governments, state corporations, private entities, and citizens is urgent. In an urban regeneration project, delegation between state and private entities is absolutely crucial. The central government and the pertinent local government must provide their support by forming new policies and repairing old institutions that are right for urban regeneration, securing the necessary subsidy, and outsourcing government-owned land development. A state corporation must play its part in every aspect that requires public character such as an overall project management of an urban regeneration project, cooperation with the local government, and infrastructure installation. The private stakeholder must share his private capital and know-hows as a construction investor and a development businessman to make possible a successful urban regeneration project. In order for these public and private entities to cooperate with one another, it is necessary to reestablish the role of a public developer and contemplate running an urban regeneration project that permeates public character through a public developer.

At this point in time South Korea is rapidly metastasizing to a aging society. A major cause of aging can be summarized as increased life expectancy, decrease of nuclear family and birthrate, and South Korea's progress is faster than any other country. From the 1970s, western society has changed social welfare to deinstitutionalization and community care because of problems about economic reason and facilities protection, so the type of elderly social service has also changed from the facility welfare service which is accommodated old people in certain facility to community welfare service which provides various welfare services with living together. Public facilities for low income group which are supported by government are lower, 6.6%, than the United States or Japan, 50%. They are divided into private manage facilities and subscription elderly facilities. These subscription elderly residential facilities show poor administration because of focusing on development and market analysis for investment returns. Therefore, in order to vitalize the elderly welfare residential facilities in Korea, we need plans about systematic services facilities for welfare and phased medical treatments. Therefore, the purpose of this study is that (1) the types and functions of residents for community elderly residential facilities in elderly welfare policies of U.S., and supported policies are researched as a transcendental model, (2) data about operating system with the principles of the market is analyzed, and (3) basic data about welfare facility plan for community residential elderly people is provided.
