This study analyzed the opinions of residents for desirable urban regeneration and suggested an improvement plan for alley environments. This study conducted a questionnaire survey of the residents living in Alley Garden of Bisan 2,3-dong, Daegu Metropolitan City. In the analysis of the importance and satisfaction of Alley Garden components, items related to a safe, cleanly environment such as 'Lighting facility installation', 'Sewage and waste disposal' and 'CCTV installation' had a high level of importance. It was also found that items improved by the Residential Environment Improvement Project and Alley Garden such as 'Lighting facility installation', 'Quantity of herbaceous flowers' and 'Kinds of herbaceous flowers' had a high level of satisfaction. The IPA results showed that items such as 'Empty house maintenance', 'Rest facilities such as benches and pergolas', 'Space for resident interaction' and 'Public parking lot' had a high level of importance, but had a low level of satisfaction, which suggests that they should be improved by priority. As a result of factor analysis, Alley Garden components were classified into four factors: 'Safety and cleanliness', 'Greenness', 'Exchange and convenience facility' and 'Aesthetics renewal'. Based on this classification, a regression analysis was conducted regarding the effects of the four factors on overall satisfaction. Results showed that all four factors had a significant influence on the overall satisfaction and that 'Aesthetics renewal' and 'Safety and cleanliness', respectively showing levels of significance at 0.274 and 0.235, were highly influential to overall satisfaction. Therefore, it was concluded that spaces for resident interaction and rest facilities should be preferentially installed to improve the environment of alleys. For the improvement of the overall satisfaction of alley environments, it was also concluded that residents should be encouraged to engage in activities such as sculpture installation and mural drawing, along with the introduction of safety bells and crime prevention environment design and the implementation of alley beautification projects.

Recently multifaceted advantages of urban agriculture are emerging in civil society and related policy arena such as food safety, environment, and social welfare. This study tried an estimation of residents' willingness-to-pay for urban farming to examine feasibility of using part of urban green infrastructure as urban farm (e.g. allotment garden). A survey targeting Bundang and Dontan new-town residents was carried out and willingness-to-pay for urban farm rental was estimated by contingent valuation method (CVM). The estimated rent was cross-checked with the rental cost and travel cost paid by hobby farm users in the outskirt of metropolitan area. The result of this study showed that the potential demand for urban farming is ample if urban farms or allotment gardens are planned within new development areas. That is, 72.6 percent of new-town residents questioned had intention of using allotment garden within urban parks and green spaces. Estimated willingness-to-pay for renting a plot, $16.5m^2$ of urban farm, was about 236,000 won(KRW), which is higher than rent for a plot of allotment garden which is located out of city. Variables which were statistically significant to estimated willingness-to-pay for urban farming were sex, age, and occupation of respondents, among other explanatory socio-demographic variables, while expected frequency and duration of visit to urban farm were insignificant.

This study aims to examine the changes in Pyongyang-bu during the late Joseon period and Pyeong-an Gamyeong through gazetteer, pictiroal maps and various literature. The results are as follows. To begin with, unlike other gamyeong, Pyongyang-bu had an exclusive government office facility from the beginning and had a different status because of the route for envoys from Ming. Therefore historical sites related to Gija were important. Second, the importance of Pyongyang city-wall increased even more through the Japanese Hideyoshi invasions in 1592 and the Manchu Invasion in 1636. However, since the post-war restoration was insufficient they focused on defense reducing the size of Pyongyang city wall. Third, as society stabilized, Pyongyangbu's finances were greatly secured. King Sukjong systematically reorganized Pyongyang city wall and facility of Pyongy-an gamyeong. The nothern wall in located high place, Gamyeong and storage in middle height and military force and guesthouse in the center of Pyongyang-bu. I-a and warehouse facilities in the far south were placed around the Daedonggwan. The urban structure that runs from Daedonggwan to Daedongmun was the same as other city. Another pertinent point is Pyeong-an gamyeong had more military facilities and rear garden and pavilion than before. In clunclusion, Pyeong-an gamyeong did not pass through three gates, but only through two gates. And it was characterized by more various space and having more pavilions than other gamyeong.

In this study, we conducted a flora survey at Mt.Bakdal (363m) and Mt. Myeongbong (245.3m) in Paju-si, Gyeonggi-do. A total of 405 taxa, including 2 forms, 32 varieties, 8 subspecies, 363 species, 261 genera, and 87 families, were surveyed in the two mountain areas. The ferns were identified as 12 taxa from 6 families, the gymnosperms as 6 taxa from 2 families, the dicotyledonous plants as 290 taxa from 70 families, and the monocotyledonous plants as 97 taxa from 9 families. The remarkable plants included 8 taxa of the Korean endemic plants, which were Populus tomentiglandulosa, Salix koriyanagi, Clematis brachyura, Viola seoulensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, and Hemerocallis hakuunensis, and 3 taxa of the rare and endangered plants as designated by the Korea Forest Service, including Tylophora floribunda as Vulnerable (VU) species, and Viola albida and Chionanthus retusus as Least Concern (LC) species. The invasive alien plants were 35 taxa, including Rumex crispus, Phytolacca americana, Cerastium glomeratum, Chenopodium album, Chenopodium ficifolium, Lepidium virginicum, Amorpha fruticosa, Robinia pseudoacacia, and Trifolium repens, accounting for 8.5 percent of the 405 taxa of the surveyed plants. We intend to further identify plants through the studies on unsurveyed areas in the western part of the DMZ, identify the native habitats of rare and specialty plants, and use them as basic data for managing ecosystem-disturbing plants.

The management methods of rooftop greening must be get ready without delay, Because rooftop greening has been generalized owing to the supporting project of The Seoul Metropolitan Government. Because most of the rooftop greening system is a recently-constructed low-management type, management methods should be made to suit it. This study is intended to set up a program for low-management rooftop greening based on "Choroktteul", the low management type of rooftop peening on the roof of one of the buildings in Seoul City Hall. Through monitoring, we found that most of the planted plants grew well but a few species needed physical management. We also found that invasive species(62 sp.) were 1.5 times as many as the planted plants. Most of the invasive plants were exotic species that need to be managed. The physical management methods were "pulling up" and "cutting". These methods should be carried out according to the growth stage. It was judged that a biological-ecological management program should be prepared through the long-period of monitoring and experiment. System methods such as guidelines of management program through monitoring was also required due to the emphasis on public ownership among the managers of the invasive species.

In November of 1994, The Seoul Metropolitan Government celebrates its sixth centennial anniversary of becoming the capital city of Korea. In celebration of this anniversary, the Government decided to construct a plaza and sought design proposals in March of 1994. The authors collaborated on a design for the Time Capsule Plaza Competition and won fourth place among twenty-six entries. In the authors' design, the traditional oriental concept of time resonates within the site through the shape of a clock, a unique planting style, and an "Ancestral Tomb" which has a time capsule inside. The plaza is meant to be a symbol of the passage of time, the cycles of nature, and the repetitive actions of man. As for the spatial composition of the plaza, in accordance with the traditional Korean way of spatial arrangement, the plaza is divided into three parts: entry, primary, and secondary spaces. In reality, the plaza is created with the primary goal of providing modern outdoor space for people to rest and gather through the creation of pleasant environments and the introduction of traditional Korean garden elements.

The research described in this report was conducted to find out how elements of the natural environment contributed to the formation of Chang'an, how its water system reinforced its status as the capital city, and what role it took for its urban function based on studies of the canal constructions. During the period of Sui and Tang, Chang'an built a sophisticated water system using Qu(渠), the irrigation facilities. In the water system, hills are called Yuan(原), and rivers with the proper environment to be developed plan into urban infrastructure facilities for irrigation water, urban living water, the composition of garden-based facility, reservoirs, and others. They improve agricultural productivity and, consequently, increase the city's competitiveness as well as contributing to the urban infrastructure, serving as a convenient source and ensuring the quality of life was abundant. So, the urban effects of the water system have raised the capital's status. With the contribution of its pragmatic water system, Chang'an not only performed its urban function brilliantly, but also established itself more firmly as a capital city.

This study evaluated how folly is experimented in the contemporary architecture after 30 years when Bernard Tchumi first introduced it to the public by the modern transformation as a garden ornament. First, folly project has been carried out based on the general concept of energizing dwindling cities. However, it has changed to the direction of adding specific programs. Also, along urban regeneration that does not change deterioration of previous structures, Folly changed in the emphasis on readjust existing structure. Second, by having different designers presenting their own follies during the Osaka Expo, folly now has part on visual exhibition element. This has similarity with public art project, yet it could more actively intervene for urban regeneration compared to conventional environment sculpture. Third, folly is experimented as the event-installation art combined form of architecture and art where people could experience the space and enjoy art. Fourth, folly enabled the landscaping of architecture and expanding city planning. Recently Gwangju Folly invited various arts, social, and cultural professionals to converge city design with architecture, landscaping, and other diverse genres.

Unlike the previous studies which have focused on 2-dimensional urban characteristics, this paper presents statistical models explaining urban heat island(UHI) effect by 3-dimensional urban morphologic information and addresses its policy implications. 3~dimensional informations of Columbus, Ohio arc captured from LiDAR data and building boundary informations are extracted from a building digital map, Finally NDV[ and temperature data are calculated by manipulating band 3, band 4, and thermal hand of LandSat images. Through complicated data processing, 6 independent variables(building surface area, building volume, height to width ratio, porosity, plan surface area) are introduced in simple and multiple linear regression models. The regression models are specified by Box-Tidwell method, finding the power to which the independent variable needs to raised to be in a linearity. Porosity, NDVI, and building surface area are carefully chosen as explanatory variables in the final multiple regression model, which explaining about 57% of the variability in temperatures. On reducing UHI, various implications of the results give guidelines to policy-making in open space, roof garden, and vertical garden management.

The aim of this study is how to understand of structural and elemental landscape image in suburban village. Nowadays, it is well known fact that suburban villages are most likely to be invaded by urbanization. Therefore, the research is focused on how the image of suburb has been changed, what patterns have been created in residential area, what are the different outcomes from different distance, and what are the changes in types of buildings, at particular village called Doojeong in Pyeongtaek city. When collecting supplemental information, elders in village have been participated in comparison of traditional and foreign. The village shows significant characteristics of such phenomenon. According to the research, there are three results. First, ironically, the structural patterns of the village is concentric as seen on urban garden, yet they do not have central function. Second, traditional homes are transformed into functional shape. The most popular roof design that takes 65 percent of whole is modernized flat roof shape. Hanok (Korean traditional house) style is disappearing. Third, due to the massive barn buildings and their monochrome, the beauty of community and architectural harmony are buried.
