  • A green area plan is getting attention as a way to solve the recent urban problems such as the rise of environment problems. To correspond to this change, there were dramatic amendments for the green area related laws. These amendments are appraised as the epochal turning point for the green area policies. This study is to introduce the main contents of amended urban green area law and urban park law in Japan, to compare with the Korean green area related laws, and to summarize the special features of both countries' green policies and the comments about the Korean green area policy structures. As a result, this amendment of Japan established the unified green area policy structure supporting the green area policies of municipal governments and is inducing living environment improvement by securing green area in the center of city, support, and the participation of residents. On the other hands, this amendment of Korea is a lack of the systemization of green area policy and the phased establishments of green area plan in spite of the scope of whole city because of absence of the unified high level plan.

  • The present study illustrates a method for monitoring the urban vegetation around Shaoxing city, Monitoring spatiotemporal changes in urban areas will become increasingly important as the number and proportion of urban residents continues to increase. The synoptic view of urban land cover provided by satellite and airborne sensors is an important complement to in situ measurements of physical, environmental and socioeconomic variables in urban settings. The results obtained have revealed a notable change in the vegetation cover in and around the City premises. In this study, we discussed methodology for measurement of urban vegetation and vegetation distributions based on band ratioing in Shaoxing city using Land sat TM imageries. A systematic analysis of the spatiotemporal dynamics of vegetation in urban areas is required to ensure a healthy sustainable environment.

  • We analyzed diurnal variations in the surface air temperature using the high density urban climate observation network of Daegu in summer, 2013. We compared the time elements, which are characterized by the diurnal variation of surface air temperature. The warming and cooling rates in rural areas are faster than in urban areas. It is mainly due to the difference of surface heat capacity. In addition, local wind circulation also affects the discrepancy of thermal spatiotemporal distribution in Daegu. Namely, the valley and mountain breezes affect diurnal variation of horizontal distribution of air temperature. During daytimes, the air(valley breeze) flows up from urban located at lowlands to higher altitudes of rural areas. The temperature of valley breeze rises gradually as it flows from lowland to upland. Hence the difference of air temperature decreases between urban and rural areas. At nighttime, the mountains cool more rapidly than do low-lying areas, so the air(mountain breeze) becomes denser and sinks toward the valleys(lowlands). As the result, the air temperature becomes lower in rural areas than in urban areas.

It was classified into sex biotope types and the project background of each sites was analyzed. The contents and technique on the basis concept, survey of environmental and biotic condition planning and design(zoning and use planning, target selection and management), preparation and management of natural environment and management, and monitoring was analyzed. It was planned out the projects in order to create the nature experience space in urban area. It was found that development of ecological urban open space by the biotope creation technic was based on three types(environmental transfer, environmental creation, and environmental inprovement type). Also most cases of projects created the biotope by the conservation of the present enviroment and ecosystem. When the development of ecological urban open space was planned, selection of target species was seemed to very important that clearly propose to the guidelines.

  • It is well known that urban relative humidity has continuous decreasing trend owing to the influence of urbanization. The change of relative humidity is directly influenced by two factors, namely, temperature effect and water vapor effect in various urban effects. In this study, the temperature and tile water vapor effects on the relative humidity change were analyzed by using monthly mean relative humidities for a long period($1961{\sim}2005$) in Daegu and Chupungnung. The major results obtained in this study can be summarized as follows. Firstly, the urban dryness was caused mainly by water vapor effect in summer. But, for the other seasons, the urban dryness is mainly due to the temperature effect. Secondly, the relative humidity in Daegu is on the decrease until now. This phenomenon is similar to another Korean huge cities such as Seoul, Daejeon and Incheon. But, it is different compared with Japanese huge cities such as Tokyo, Osaka and Nagoya, indicating a standstill in relative humidity change after 1980s.

  • Heat island phenomena in Chuncheon (Korea) were investigated using air temperature measured by automatic weather stations and temperature dataloggers located at rural and urban sites. Numerical simulation of the phenomena was performed using Weather Research and Forecasting Urban Canopy Model (WRF-UCM) and results were compared with the observation. The model was initialized with NCEP/FNL data. The horizontal resolution of the fine domain is 0.33 km. The results of observational analyses show that the intensity of heat island was significantly higher during the nighttime than during the daytime. The highest measured temperature difference between rural and urban site is $3.49^{\circ}C$ and average temperature difference varies between 1.4 and $1.9^{\circ}C$. Good agreement was found between the simulated and observed temperatures. However, significantly overestimated wind speed was found at the urban sites. The linear regression analysis between observed and simulated temperature shows high correlation coefficient 0.96 for urban and 0.94 for rural sites while for wind speed, a very low correlation coefficient was found, 0.30 and 0.55 respectively.

  • Regarding urban design in this 21st century, cities pursue human-oriented urban design through which nature, cities, and human beings are unified and interact with one another. For such urban design maintenance, it is needed to conduct systematic analysis and synthesis on various and complex factors of cities expressing urban images. Also, it is necessary to secure methods to evaluate those cities based on urban users' visual information. Thereupon, this study aims to suggest urban design evaluation methods which accept human behavior or needs and also allow us to figure out desirable images. For this, the study established the construction system of the most basic urban design components that form cities through literature review and expert evaluation. And it examines correlation among those factors with statistic means. Through this, the study suggests a new urban design evaluation system and evaluation process divided into experts and users so as to reflect user behavior or needs.

  • Previous studies have shown that forest therapy program can help prevent dementia. However, few studies have focused on low-income elderly people living alone. The current study examined the meanings that the elderly living alone receiving medical care assigned to the urban forest therapy program, as a way to understand the pathways that nature-based intervention affect preventing dementia. Twenty-one participants were recruited and they participated in a five-week urban forest therapy program. Semi-structured interviews were carried out with 21 participants who experienced the urban forest therapy program, and analyzed qualitative data using thematic analysis. Results showed that all themes identified were related to connectedness with oneself, neighbors and nature. Awarenesses of change were consisted of positive and negative themes. The themes of positive awareness were improvements of mental and emotional condition, feelings of isolation and loneliness, and health-related lifestyle. The negative themes were terminations of short-term programs and inconvenient access to the urban forest. Based on these data, we suggest an urban green welfare framework for future research and interventions for preventing dementia of underprivileged elderly group.
