본 연구에서는 도시텃밭 프로그램이 공동체의식에 미치는 효과를 규명하고자 서울의 3개 공공도시텃밭을 선정하여 설문조사를 실시하였다. 연구결과는 다음과 같다. 첫째, 텃밭프로그램이 참여자의 상호교제와 공동체의식에 미치는 영향이 다각도로 확인되었다. 지속적 프로그램이 있는 텃밭과 그렇지 못한 텃밭 사이에는 내부교제와 공동체의식에서 차이가 있었으며, 프로그램참여자가 비참여자에 비해 높은 수준의 텃밭활동, 내 외부교제 및 공동체의식을 보였고, 경로분석에서 도 프로그램참여가 공동체의식에 가장 큰 영향을 미치는 변수로 나타났다. 둘째, 자가점유, 거주기간, 참여인원이 공동체의식에 영향을 미치는데, 이는 거주기간이 긴 자가점유자, 특히 1인 및 노인 가구 등 사회적 소외계층을 대상으로 텃밭프로그램이 운영되어야 함을 시사한다. 셋째, 농업교육보다 지역사회와 연계된 다양한 문화 프로그램의 만족도가 높았다. 이 결과들은 도시텃밭의 공동체의식 형성효과를 높이기 위해서는 지속적이고 다양한 프로그램이 필요함을 보여준다.

This study is conducted to estimate the air temperature decreasing effects by restoring urban streams using WRF/CALMET coupled system. The types of land use on covered streams are constructed with the land cover map from Korea ministry of environment. Restoring covered streams changes the types of land use on covered areas to water. Two different types of land use(CASE 1 and CASE 2) are inputted to the WRF/CALMET coupled system in order to calculate the temperature difference. The results of the WRF/CALMET coupled system are similar to the observed values at automatic weather stations(AWS) in Busan area. Restoring covered streams causes temperature to be decreased by about $0.34{\sim}2^{\circ}C$ according to the locations of streams and the regions that temperature is reduced are widely distributed over the restored area. Reduction of temperature is increased rapidly from morning and maximus at 13LST. Natural restoration of streams will reduce the built-up area within urban. With this, temperature reductions which are the cause to weaken the urban heat island appear. Relief of urban heat island will help to improve the air quality such as accumulation of air pollutants in within urban area.

The purpose of this study is to analyze the uses and exterior design of the balconies in urban housing from the ancient times to the 19th century. In doing so, the paper seeks to investigate the cultural identity of the balcony in urban housing. The results are as follow. First, in the urban housing the balcony space were made for protection from the heat, light and ventilation; gardening; views toward the streets, city, waterside, inner court, domain for men; breathing french air; watching ceremony, festivals and events; simple houseworks like drying, carpet cleaning and hair coloring; lever installation and fire escape. Second, as part of exterior design the typical projecting characteristic of the balconies was emphasized and they became an impotent decorative element. The monotonous facade changed to a lively design with a rhythmical sense. On the facade the effects of horizontal movement, symmetry or asymmetry from the main entrance, and the center-projection (rialto) were created. In the urban housing the balconies were used for cultural activities which supplement and enlarge the function of the interior space, and moreover the rich effects of the facade contributed to the creation of attractive urban landscape.

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.

The purpose of this study was to explore socio-economic effects of participation in weekend farming. This study was carried out through review of literature and descriptive survey. The data for the study were gathered from 135 randomly sampled urban people who participated in the weekend farming activity. Small scale weekend farming activity of the urban people led them to better quality of life in terms of educational and socio-economic conditions. The major findings of the study were as follows; 1) Weekend farming supplied fresh vegetables to participating urban households, however, showed relatively low economic effects. 2) Participating urban people have experienced new relationships with other participants and could better understood their family members of weekend farming activity. 3) Participating urban people responded that they could improve their quality of life through weekend farming activity. 4) Weekend farming activity proved to be a useful educational experience for children and youth.

The surface changes due to urban expansion and the increase of artificial heat releases have brought significant climate changes such as heat island phenomenon in urban area. Furthermore, these changes also have brought serious problems such as air temperature increase, wind changes, and air pollution in urban area. Comprehensive analytical technologies considering various effects are required to analyse complicated mechanism of climate changes, and review the efficient measures. In this research, the effect of the urban expansion in Tokyo and Bangkok area on urban environment will be discussed. By using CFD, urban development and the mechanism of global warming and wind change are studied in those two cities. As a result of numerical research, the surface changes of city could bring the environmental changes in urban area.

To study the temperature mitigation effects from urban green, several arrangements of green spaces were selected and air/ground temperatures were measured in Chongju city area. The results of this study can be summarized as follows; 1. It was found that the natural ground materials effect more affirmatively on the air and ground temperature than artificial ones do. The best results were recorded from the grass surface presenting highest mitigation effect and lowest daily temperature deviation. 2. Temperature mitigation effects of Tree-Shade on ground are different from season, ground material, and crown-size. Them most effects were found in interlocking block, the least in grass surface among recorded 2 seasons and 3 materials. In case of air temperature, the effects were more or less decreased in most cases. 3. From the survey, it was confirmed that the smaller urban greens can do its role of temperature mitigation as larger ones does. In case of this study, the effect was recorded about 2.3$^{\circ}C$.

The number of environment-related technologies has increased remarkably over the past two decades, as has the public's interest in effective resource use and ways to reduce the effects of global warming. Industries that are based on environment-related technologies are thus growing rapidly. Previous studies revealed that externalities derived from the population concentration in urban areas positively affect agglomerations of high-tech industries. Such externalities have been named the "knowledge spillover effect". The purposes of the present paper are to (1) give a thumbnail sketch of the locations of environment-related industries around the world, using the Organisation for Economic Co-operation and Development environment-related patent statistics, and (2) explicate the effects of the Marshall-Arrow-Romer (MAR) and Jacobs externalities, which result from population concentrations in urban areas, on the agglomeration of environment-related industries in Sweden. The analysis revealed that environment-related industries are located chiefly in urban areas across the globe, and that only the MAR externalities influenced positively on the agglomeration of these industries in Sweden.

Urban land consolidation, which is to reform land parcels to remove fragmentation and produce ideal blocks, is an effective means for urban renewal. Successful urban land consolidation brings out great benefits to the city officials as well as general public, such as improved city image, increased land value, and more effective land use. However, urban land consolidation can be detrimental to environment, especially in the ecological aspects, while the execution of land consolidation has been focused solely on development for the sake of human benefits. To remove negative effects of urban land consolidation to the ecological system, this paper is intended to establish a set of criteria for evaluating ecological impacts of an urban land consolidation plan. Firstly, key ecological indicators are identified using a special group decision-making process called "habitual domain analysis" and then individual weighting of each indicator is recorded by analytical hierarchy process. An urban ecological evaluation model with 4 levels and 23 indicators is thus developed.
