This study aimed to compare the two support systems related to real estate that the neighborhood association owns (citizen self-governing organization and approved territorial groups) in Kawazaki City, Kanagawa prefecture, in order to review the details of support given. The research method was interview and literature research, conducting an analysis of the characteristics and issues of the support system. The results revealed the following: 1) the financing system at the time of acquiring the system is important, 2) It is important to improve the revenue by renting out the facilities.

In this paper, we declare the inside and outside temperature, humidity, IAQ field measurements for traditional houses and apartment house in order to evaluate their levels in the living environment in Sunan Yugur Autonomous County of Zhangye City, Gansu Province, China.
This study has been conducted directed at the climatic and residential environments and local residents of western China.
It is founded on Japan-China joint research, built on physical measurements and questionnaire surveys that enable healthy and sustainable development, on the basis of assessment of the climate and environmental characteristics of western China. Additionally, the project aims at proposing convenient methods to protect people against the adverse health effects of climate change. Focusing our attention on the state of housing in rural parts of Sunan County and on the characteristic abundance of natural energy resources, we set out to develop a new model for energy-efficient housing adapted to available natural energy sources.
We assessed the state of current lifestyles and customs, and living environments in western China, by means of both physical measurements and questionnaire surveys. Also proposed a new type of energy-efficient housing based on an understanding of ethnic culture, social and economic conditions, and climatic conditions in the applicable area utilizing design support tools, by introducing an engineering design theory and calculation technique centered on heat and satisfying basic performance requirements.

The subspace theorem due to W. M. Schmidt implies that the unit equation in three variables has only finitely many solutions except trivial cases. However, there is no effective method in general to determine the solutions, hence very few examples of explicit solutions are known. In this article, we give a complete list of the integer solutions to an exponential Diophantine equation in three variables, which is indeed one unit equation in three variables.
