Urban parks and open spaces provide the community residents with the most easily accessible source for outdoor recreation, contributing also to the improvement of quality of natural environment in urban area. The demands of urban residents' for more and better green area are ever-increasing. However, the level of most urban open spaces which are easily accessible for residents are not satisfactory to meet the residents' demand in availability and in quality as well. Most existing urban open spaces are simply built of green areas only or have been developed in almost identical design with little consideration for individual uniqueness of the site. When developing neighbourhood parks in urban housing complexes, for example, little consideration is being given to topographical conditions, interrelation with the adjacent green area, or viability of the urban ecosystem. In many cases, urban park development projects are being done with serious negligence of natural properties of the site, by even destroying existing healthy woodlands. for instance. The objectives of this study are; -To survey on the domestic and the overseas cases of regulatory systems, development status and planning methods for urban open space. -To identify underlying issues of residental park developments in urban housing projects and establish appropriate improvement measures thereof, by studing and analyzing current-use data of developed urban parks and management status thereof. -To establish improved standards for urban open space planning, by integrating above surveys and studies, and recommendation for revision of related legislation is also presented to implement these standards.

The annual variations of the urban heat island in Busan is investigated using surface temperature data measured at 3 automatic weather stations(AWSs) for the 5 years period, 2006 to 2010. Similar to previous studies, the intensity of the urban heat island is calculated using the temperature difference between downtown(Busanjin, Dongnae) and suburb(Gijang). The maximum hourly mean urban heat island are $1.4^{\circ}C$ at Busanjin site, 2300LST and $1.6^{\circ}C$ at Dongnae site, 2100LST. It occurs more often at Dongnae than Busanjin. Also the maximum hourly mean urban heat island appears in November at both sites. The urban heat island in Busan is stronger in the nighttime than in the daytime and decreases with increasing wind speed, but it is least developed in summer. Also it partly causes the increasement of nighttime PM10 concentration.

The urban population in Asia more than doubled between 1960 and 1985, growing by 3.0 percent per annum on average. Yet during that period, the proportion of the total population living in urban areas increased only from 21 to 27 percent. This seeming paradox is explained by the relatively high rates of rural population growth in Asia, which averaged 1.8 percent over the same period. The Republic of Korea has experienced the most rapid rate of urbanization in Asia during the past century. The proportion urban jumped from 28 percent in 1960 to 65 percent in 1985. There is a clear association between economic growth and the pace of urbanization in Asia. Currently natural increase accounts for about 60 percent of urban growth, but the speed of urbanization is projected to increase after 1990, and migration, reclassification and annexation will comprise about half of urban growth, Seoul is currently the fourth largest urban agglomeration in Asia, and its population is projected to be over 13 million by the end of the century. It is argued that policies to deconcentrate urban population will not be generally successful in Asia and that governments should attempt to manage the growth of large metropolitan areas more efficiently.

Ant communities are well suited for monitoring changes in ecosystems. Although numerous studies have examined the responses of ant communities to environmental disturbance, relatively few long-term studies on ant communities have been undertaken in urban environments. We examined species richness in nine urban parks in Hiroshima, Japan, and compared the survey results with data collected at the same sites by using the same methods in 1999. In both surveys, total of 25 species was recorded: 23 species in 1999 and 20 species in 2012. Non-metric multidimensional scaling analysis revealed that the ant communities consisted of two distinct groups, which could in turn be characterized by three patterns of ant community changes in between the two groups. The first of these community change patterns was characterized by a shift within group 1, but the number of species remained constant (approx. 10 species). The second pattern was characterized by a shift within group 2, but the number of species remained low (approx. 4 species). The third pattern was characterized by a shift from group 1 to group 2 as the abundance of Linepithema humile (Mayr) increased over time. Unlike the first and second patterns, the number of ant species in communities of the third type decreased significantly. These findings suggest that L. humile has a marked effect on the species diversity of indigenous ant communities in urban environments.

Increased consensus among gerontologists exist on the need to pay greater attention to the reciprocal relationship between the social and spatial in order to understand the construction of aged identity and everyday lives of old people. With urbanization, spaces are increasingly age-graded and as a consequence, urban elders are socially isolated from the community. In this study, we examine the social interaction patterns in various places specifically designated for the elderly, such as the Senior Center, Senior Welfare Center, and Hall for the Aged in Seoul. Main purpose of this study is to understand everyday life experiences of space the elderly people residing in the city go through. Data were gathered through qualitative, case study method. Results show that such spaces were important sites for social interaction for urban elderly who lacked social spaces after retirement and active parenting role. Also, it was shown that each place presents different contexts for social interactions and certain components of social class differences existed. Heterogeneity within the participants of each place was also observed. Quite strong stereotypes about certain places were also observed among the urban elders. Based on these results, importance of developing a 'community perspective' in the study of old age is discussed.

As the instability of international societies on the energy resources has increasingly been deepened due to excessive use of fossil fuels, the importance of energy saving and global environment protection has highlighted, So the interests in environment-friendly and stable new & renewable energy have been dramatically increased. The studies on reconstructing the old-fashioned towns economically, socially and physically have been also significantly increased. In this urban regeneration, renewable-energy using systems were aggressively applied to overcome the energy and environmental problems of the existing towns. There have been many of studies on the compound applications of the renewable-energy using systems in the advanced countries while they are insufficient in Korea. As a preliminary study of urban renewable-energy using system development, this paper surveyed the foreign cases applied to key technologies such as geothermal energy, hydrogen fuel cell and bioenergy among the renewable-energies in urban built environment.

Recently there have been great interest in the street landscapes, and numerous studies have been investigating shaping processes of urban landscapes, legal systems for scenery management, landscape preference and evaluation techniques. However, there are only few studies investigating how planting types influence on street landscape evaluation and how the relationships among street landscapes are. This study aims to make a guidelines which can be used for securing afforestation in urban settings and improving urban environment. In specific, the results of this study can provide guidelines for urban street design and the base knowledge for identifying appropriate requirements for better street landscapes. We identify factors which make shape certain images of street landscape, and draw physical factors influencing on visual appropriateness through visual landscapes evaluation process. To evaluate landscapes according to planting types, on-the-spot survey at 14 streets in Gang-Nam district were made. The district is under executing street improving projects and shows the most satisfying planting types. To evaluate street landscapes which people experience during their walking, 100m of continuous streets are chosen. The survey sites exclude streets with irregular pattern, are adjacent to large urban parks or are used as parking spaces in part. We evaluated 9 street landscapes classified into 1-line-planting, 2-line-planting and 3-line-planting on the basis of the location of planting and the planting methods.
