The study was conducted to present the criteria of plant selection and planting design pattern suitable for the vegetation blocks which are becoming more popular for the facade greenery in urban areas. The main results are summarized as follows. 1. Under irrigated conditions, the plant grew better than that of unirrigated conditions and herbs grew better than shrubs. In selection of shrubs, it would be more proper to consider the size and depth of the pockets. 2. Under unirrigated conditions, Sedum middendorffianum and foreign sedums grew well, so it can be concluded that sedums can grow at low management condition. And, Hosta longipes and Aceriphyllum rossii could be survive at low management conditions only if irrigation was conducted at dry season. But, shrubs needed irrigation management for survival at vegetation blocks. 3. The results of this study, it can be concluded that greenery of walls and retaining walls might be effective for the creation of green space, improvement of urban landscapes, and the creation of diverse biotopes in urban areas with vegetation blocks.

Since the industrial revolution, the global environmental problems such as greenhouse gas accumulation and the average temperature increase have caused people's attention. 'Low Carbon, Green Growth' was presented to cope with these global concerns, as one of main policies of 2008 in Korea. The paradigm of a green urban development is started to concern the whole city's energy problems owing to realize 'Low Carbon, Green Growth' in the urban side. The government established a nation's basic energy plan for 20 years, and some local cities made efforts to develop new renewable energy such as the solar, wind and water energy which are suitable to each city's character. As a part of these efforts, the concept of U-Eco city is newly appeared to reflect upon ubiquitous technique, urban ecology and the next generation energy system. However, urban plan is difficult to adopt this next generation energy system with existing laws, regulations and technical systems. The new executive and systematic system is needed to realize the U-Eco city U-Eco for the management of an efficient city. In this study, the authors investigate the concept of the next generation energy system and U-Eco city to realize the energy-efficient city plan and analyze problems to occur during the application of them in an existing city plan. Then, the authors show the remedies to deal with occurred problems.

The regeneration of built-up areas is considered as one of the necessary measures for the effectiveness of urban growth management. In this vein, this study explores how to limit the number of people who leaves the built-up areas and to restore the area with the resident. For this, a residential area of the built-up area is analyzed in terms of why people in that area are moving out of the area and who fills in it after all. This study founds that narrow roads in a residential area and the changes in land use from residential purposes to commercial are major forces that push the people in the built-up area. In addition, the lack of welfare facilities, the pavement of roads, and pedestrian roads. education. crime. the lack of interaction between neighbors, and the quality of housing are all emerged contributing the loss of people in the built-up areas. It is recommended that all the factors here should be restored in an appropriate way. Another finding is that those who fill in the built-up area are largely over 50, self-employed, comparably wealthy, and having their own families. Hence, it is advised that the built-up area would be rearranged in order to attract those type of people in there.

This study focuses on the regeneration of multi-dwelling residential estates located already in built-up areas. This study focuses on policy measures and surveys of remodeling and analyses the likelihood of remodeling and prospect of it. These major findings were diseased: First, people have changed their propensity about renewing their residences from reconstruction to remodeling. This would account for the likelihood of remodeling and its popularity. Second, unlike the stronger demand for remodeling, over half of people respond express that they are reluctant to pay the costs involved in renewing the public spaces of their apartment complexes. This argues that it would be necessary to review policy measures in other countries. Reducing financial burdens of those who are willing to remodel their residents and to trigger their participations. In addition, the costs should be saved from the outset of constructing new buildings. With the suggestions drawn in this study, the remodeling should be regarded as a considerable measure to renew the residential areas, especially where the area is already built-up and the development density is severely limited.

China is experiencing the urbanization at an unprecedented speed and scale in human history. The continuing growth of China's big cities, both in city land and population, has already led to great challenges in China's urban planning and construction activities, such as the continuous increase of construction and demolition (C&D) waste. Therefore, how to characterize cities' construction activities, particularly dynamically quantify the flows of building materials and construction debris, has become a pressing problem to alleviate the current shortage of resources and realize urban sustainable development. Accordingly, this study is designed to employ 4D-GIS (four dimensions-Geographic Information System) and Internet Plus to offer new approach for accurate but dynamic C&D waste management. The present study established a spatio-temporal pattern and material metabolism evolution model to characterize the geo-distribution of C&D waste by combing material flow analysis (MFA) and 4D-GIS. In addition, this study developed a mobile application (APP) for C&D waste trading and information management, which could be more effective for stakeholders to obtain useful information. Moreover, a cloud database was built in the APP to disclose the flows of C&D waste by the monitoring information from vehicles at regional level. To summarize, these findings could provide basic data and management methods for the supply and reverse supply of building materials. Meanwhile, the methodologies are practical to C&D waste management and beyond.

Background and objective: This study was conducted as part of research to promote garden diversity and seek sustainable garden management plans, as well as to determine the trends in understanding and use of companion plants as an eco-friendly farming method and provide the results as the basic data for sustainable urban agriculture. Methods: To determine the trends in garden activities, eco-friendly pest control, and use of companion plants, a survey was conducted on 230 urban residents participating in the Urban Agriculture Expert course. 223 copies of the questionnaire were collected excluding missing values, and IBM SPSS statistics Ver. 25 Program was used for frequency analysis, descriptive statistics, and regression analysis. Results: Most of the respondents were female (71.3%), homemakers (26.5%), were in their 50s (29.1%), and had 2 members in the family (27.8%). 164 respondents (73.5%) had experience in gardening, most of them once a week (31.7%) and for self-consumption (55.5%). Both men and women raised crops for safe food production (32.3%), and they most preferred the city garden type (39.9%). For the preparation of nourishment for eco-friendly garden management, most respondents (60.1%) purchased fertilizers from the market. For the reason why eco-friendly pest control is necessary, all respondents except 4 of them (98.2%) responded that it is necessary 'because it affects my health as I eat it (73.5%)', indicating that they still had a high level of interest in health. Only 43.9% of the respondents said that they had heard of companion plants, 89.2% responded that companion plants were effective in eco-friendly management, and 87.4% showed the will to participate in gardening using companion plants in the future. Finally, the regression analysis confirmed that the awareness of companion plants and satisfaction with gardening activities are key variables that increase the intention to participate in gardening activities in the future. Conclusion: Since plants require special care depending on the period and various diseases and insect pests occur, there must be continuous research on companion plants as an eco-friendly farming method. Moreover, by actively using companion plants in urban gardens with the utility value in not only eco-friendly pest control but also in helping plant growth, urban agriculture is expected to be continuously activated and promoted by increasing satisfaction in gardening activities with aesthetic landscaping and pest control.

Buildings in the city acts as a cause of distorted wind direction, wind speed, causing the stagnation of the air flow. In the recent trend of climate change can not but consider the temperature rise of the urbanization. This study was aimed to analyze the thermal comfort of planetary boundary layer in different artificial constructions areas which has a direct impact on urban climate, and estimating the warming phenomena. Envi-met model was used to consider the urban structure associated with urban growth in order to precisely determine the impact of the building on the city weather condition. The analyzed values of thermal comfort index were temperature, wind speed, horizontal and vertical turbulent diffusivity. In particular, analysis of the PPD(Predicted Percentage of Dissatisfied) represents the human thermal comfort. In this study, by adjusting the arrangement and proportion of the top floor building in the urban it was found that the inflow of the fresh air and cooling can be derived low PPD. Vertical heat flux amount of the city caused by climate change was a factor to form a high potential temperature in the city and the accumulation of cold air does not appear near the surface. Based on this, to make the city effectively respond to climate change may require a long-term restructuring of urban spatial structure and density management.
