Street gardens, a series of streetscape improvement projects led by Seoul City Government, are initiated for the purpose of providing aesthetic satisfaction and mental refreshment to pedestrians. In order to investigate whether street gardens indeed promote the psychological health of the users, questionnaire surveys were conducted on three selected street gardens - at Gangnam-daero, Digital-ro, and Teheranro - and their comparison sites located on the same streets, which have a similar physical environment but without a street garden. The survey questionnaires, based on Attention Restoration Theory, were composed of Perceived Restorativeness Scale-11 with the eleven individual questions grouped into four categories: 'Fascination', 'Being away', 'Coherence', and 'Scope'. The survey questionnaires also ask about physical components that promote psychological improvement in the aforementioned categories. The collected data was analyzed with factor analysis, reliability analysis, and independent t-test. The results suggested that street gardens had a relatively positive effect on the psychological restorativeness of the users. In particular, they gave fascination and interest to the users. However, they did not offer a feeling of being away to the users, which revealed the limitation in the psychological improvement effect of street gardens. The physical components of the street garden that have led the psychological restorativeness effect were wooden bench, tree, and flower. This result corresponds to an extant theory that natural factors have a positive effect on the psychological restorativeness within a hardscape. This research will shed light on the planning and design guidelines for the street garden project.

This study aims to examine at the garden characteristics of salt merchant in Yangzhou, China during the Ming and Qing Dynasties, I looked at the background of garden formation through the literature. In addition, analyzed the garden design method and components of salt merchants. The results were as follows; First, the Yangzhou area in the past has achieved cultural and economic development with the establishment of the ancient Grand Canal. Salt merchants accumulated wealth through trade, and created many gardens under the background of securing materials for create garden through trade, forming political forces through the cultivation of students, and inflow of foreign cultures. Second, salt merchants in Yangzhou asked garden experts to design and create the garden as a place for exchange and relaxation. Also, through the production of landscape changes using Gasan(假山) and a long corridor(長廊), clear classification of spaces using architectural elements, and the placement of buildings in scenic areas adjacent to the water, the gardens with practical and aesthetic functions were owned. Third, the gardens of Yangzhou Salt Merchants have a building-oriented commercial space on the front, and a garden-centered design characteristic on the back. The garden of the commercial zone was built in a simple form using pots, oddly shaped stone, bamboo and fence patterns in the remained space, focusing on the front of the building. The garden at the back formed a curved waterway connected to the canal is refracted across the garden. The garden also features piled stones(疊石), stone bridges and ship-shaped stone building(石舫). In addition, the design reflected the introduction of trees that take into account the climate and color contrast of Yangzhou province, pavement of various materials and patterns.

This study was executed to find out how to improve the planting and use of landscaping plants in Chuncheon. The number of street trees was 17,877 in 2003. The major species of street trees were Ginkgo biloba(52.7％), Prunus sargentii(15.3％), Zelkova serrata(8.9％), Platanus occidentalis(7.3％). Salix babylonica and Platanus occidentalis were decreased, while Prunus sargentii and Zelkova serrata were increased. Salix babylonica is a good species for a lakeside city, but its seeds cause allergies to some people. Most of the trees have been removed in Chuncheon. The planting of Salix babylonica(♂) resulted in no problems, and it should be propagated to plant. The soil of several areas was analysed to investigate soil conditions. The outskirts of city had good conditions in pH, organic matter and minerals, but the downtown areas had high alkalic, due to alkali from footpath concrete blocks. Appropriate pruning adds to the aesthetic and prolongs the useful life; it also requires less managing of insects and diseases to maintain good healthy of street trees. Street trees were not properly pruned due to electric lines and shortage of pruning information. The pruning was controlled by Korea Electric Power Co, which has no pruning information. Pruning must be maintained by a professional landscape company to maintain good shape such as with Bonsai. The Shrubs planting zone between street trees and other trees, and preservation plates were established for healthy of street trees. They have to be repaired and maintained well to keep better environmental conditions. The number of tree and flower species of 68 schools in Chuncheon were 12 and 16, respectively. The species that showed high preference were Juniperus chinensis, Pinus koraiensis, Pinus densiflora, Rosa centifolia, Forsythia koreana, and Rhododendron schlippenbachii. The high frequency of the protection trees designated by Chuncheon were Pinus densiflora, Ginko biloba, Zelkova serrata, Quercus species. It was thought that the diversification of street tree species, the selection of street trees suitable to each space, the generalization of use of native species, the appropriate pruning and proper fertilization, the control of pests and diseases, and the opinions of citizens concerning landscape plants were needed to improve the planting, use and maintenance of landscaping plants in Chuncheon.

The purpose of this research explain the meaning of the environmental design principles and cultural landscape pattern(dualistic space organization) of the Hahoe(河回:winding river village) the Yangdong(良洞) traditional village. Village's space organizations based on Shamanism, fin-yang and Five elements principle, Feng-shui idea, social system and Confucian ideas. And it were accomplish curat landscape pattern(village:form+object=pattern) through the frame of settlement space. As a central persons of villages(the Hahoe $.$ the Yangdong) construction, Suhae(西厓) experienced tough Chunghyodang - Wonjichongsa - Ogyonchongsa - Pyongsansowon channel(忠孝堂 -遠志精舍 -玉端精含 -脣山書院) and Kyomam(謙 ) experienced tough Yangjindang - Binyeonchongsa - Kyomamchongsa - Hwachonsodang(養眞堂 - 賓淵精舍 - 謙庵f精舍 - 花川書堂) channel. Also Woojae(愚齋) experienced tough Suhbackdang - Khankachung - Dongkangsowon(書百堂 - 觀稼停 - 東江書院) and Hoejae(晦齋) experienced tough Moochumdang - Hyangdan - Oaksansowon(無添堂 - 香壇 - 玉山書院). It is space organization of themselves interact contrast and sequence principles with competition in good faith. And ecological art-space, that is, environmental spare organizations of traditional village has been reflected harmony between nature and artificiality, spatial rhythm and sequence, spatial hierarchy between upper classes and humble class, permeability space, asymmetrical balance, aesthetic space perception. The humble classes hold a ceremony Hahoe's Pyolsingut-Talnori(maskdance drama), Dangjae(堂祭:religious service) at the Dang(堂:shamanism spot) and Yangdong's Sohraesulnori, Hohminori. And the upper class hold a ceremony Hahoe's Julbulnori and Yangdong's Chungjanori connected with culture of confucianism. Specially, the cultural structure cf the village is evidence of a contrast between the upper class and the humble classes, time, method and location of ceremony(performance).

The purpose of this study is to form a night-view at a university to satisfy users through case studies of four representative university campuses with analyzing the lighting conditions and facility satisfaction. The result of this study is following. From the present lighting status, there are 664(l9types) lightings at Kyunghee University, 350(17types) at Sungkyunkwan University and 437(l9types) at Ajou University. Main materials of the lightings are metal, iron and stainless. Moreover, most illuminants are white-colored metal-halide lamp. There is no specially designed lighting facility because ready-made goods were used. Furthermore, the locations of lightings are not suitable so some are useless. Most main spatial illuminations are not satisfying outdoor standard, so it can be concluded that the designs of present campuses are not carrying on with-out plans. From the result, present campus lighting does not satisfy the desire of users in aesthetic and functional point of view but consider the luminosity. However, even though the luminosity does not standardize the law. It is because the design does not reflect a suitable standard with desire of users and it does not have a long term plan. Moreover, the campus design has no study about development plan even though it has enough green area which has a potential possibility to overcome the lack of green areas in a city. Therefore, it is needed to design a comprehensive campus plan which satisfies the desire of students and residents with considering promotion of excitement and harmony through adjusting luminosity of the lighting facilities and supplying various lighting resources.

Unlike conventional roof landscaping, where various kinds of plants and structures are employed, a grass roof is a roof on which herbaceous plants are grown in planting medium and which is not accessed or maintained, mainly because it doesn't have sufficient load capacity to support a regular roof garden. They are mostly built on existing roofs, whether flat slab or gabled. Planting on roofs has numerous advantages, such as creating a biotope, purifying urban air, adding moisture to the atmosphere, storing rain water, preventing flash floods, reducing energy use for heating and air conditioning, enhancing the urban landscape and providing relaxation to the city dwellers, not to mention the alleviation of global warming by absorbing $CO_2$. In addition to the general merits of roof planting, the grass roof has its own unique qualities. Only herbaceous species are planted on the roof, resulting in light weight which allows roofs of existing buildings to be planted without structural reinforcement. The species chosen are mostly short, tough perennials that don't need to be maintained. These conditions provide an ideal situation where massive planting can be done in urban areas where roofs are often the only and definitely the largest space available to be planted. If roofs are planted on a massive scale they can play a significant role in alleviating global warming, heat island effects and energy shortages. Despite the advantages of grass roofs, there are some problems. The most significant problem is the invasion of neighboring plants. They may be brought in with the planting medium, by birds or by wind. These plants have little aesthetic value comparing to the chosen species and are usually taller. Eventually they dominate and prevail over the original species. The intended planting design disappears and the roof comes to look wild. Since the primary value of a grass roof is ecological, a change in attitude towards what constitutes beauty on the roofscape is necessary. Instead of keeping the roof neat through constant maintenance, people must learn that the wild grass with bird's nests on their roof is more beautiful as it is.

In this study, the landscape of Insa-dong was interpreted from the viewpoint of a social construction of landscape, which regards the dynamic process of landscape change as more important than landscape visibility. This viewpoint also regards landscape as the result of its interaction with certain actors. From a review of previous studies on the same subject, it was found that the physical environment, institutions, and images are essential factors influencing landscape change. Insa-dong, which was Kwanindaing and Daesadong during the Joseon Dynasty, acquired symbolic meaning as a traditional area during the Japanese colonial period because of its many antique shops and Korean-style buildings. In 1970, the establishment of modern galleries in the district added to its image as a haven of the traditional Korean culture. Insa-dong thus eventually came to be referred to as "the street of traditional culture" by the people of Korea. Thanks to global festivals like the Asian Games, the Olympics, and the World Cup, Insa-dong's reputation as a cultural tourist destination has become stronger as these festivals created a need for a place in Korea where the country's traditional culture can be showcased to foreign tourists. After the mid-1990s, the merchants of Insa-dong began to cash in on the district's image as a showcase of traditional Korean culture due to the economic depression that emerged then. The people of Insa-dong and those outside it, however, came to feel that this trend damaged the district's image. Therefore, the people of Insa-dong and the district's local government started a movement to restore the aesthetic value and symbolic meaning of the district's landscape. This effort induced institutional change. Insa-dong used to be a natural haven of traditional Korean culture. Its landscape has recently been reconstructed so that this image could be restored. This process was made possible by the active interaction of diverse people: merchants, users, administrators, and NGOs.

This study is to interpret how landscape aesthetic characteristics of moderation, which is the point of human-oriented neo-confucianism vision, are projected to the landscape organization of a Dodong-SeoWon, known for its overflow to neo-confucianism grounds and standards among domestic SeoWon. The aspects of neo-confucianism discussion in the shape of Dodong-SeoWon with the beauty of from and contents dominating the landscape of Dodong-SeoWon different from constructive completeness as 7 external and internal landscape organization including placement, circulation, setting, vista, fencing, naming, and decoration are as follows. The left direction of Dodong-SeoWon, part of external organization, is the result of landscape organization that emphasized the stage of moderation through the unification of man and nature by naturalizing natural direction to human-oriented directions. Important aspects to rule external orders and standards of Dodong-SeoWon are principles of one classes based on ranks and bilateral symmetry that is the unity of setting and circulation landscape organization from penetrating the spirit of moderation with no bias. By securing territoriality by fencing the unity of verticality and horizontality, the landscape organization to reach moderation is expressed. Meanwhile, Suwoloo(水月樓) perceived on the floor of central assembly hall, the formation of time frame from roof piles of Hwanjumun(喚主門) as well as pilars of Jungjeongdang(中正堂), and rime link method inducing visual balance and openness through segment, combination, and others are vista organization that show the ideality of unique neo-confucianism building. Also as part of landscape organization contents. semantically, building name including arrangement from Taegukdoseol, ideological naming following the name of Ssanggye-SeoWon, which is the former body, the name of the hall symbolizing the transfer of neo-confucianism enlightenment, impartiality with no bias, as well as Geoinjae(居仁齋) and Geoijae(居義齋) based on olympic, are also results of applying neo-confucianism standards. Additionally. the SeoHoe(瑞花) expressing the change of IleumIlyang(一陰一陽) on the stylobate of Jungjeongdang, Saeho(細虎) which goes up and down, as well as Simul made of four dragons, are artistic expression of the moderation that symbolizes the harmony of ying and yang with no exceeding or insufficiency. Humorous and unique rocks and stones evenly arranged in all spots of Dodong-SeoWon are to promote anti-strict organization by offsetting the image and external order of the lecture hall as strict as it is, and this is very ironic as it is the other landscape organization in different dimension as well as the expression of moderation.

This study aims to examine what factors citizens value in urban parks and green spaces in terms of usage and aesthetic value and to find ways to deal with the changing patterns of user satisfaction for these various green elements. To achieve this, the study developed a dynamic model employing a transactional approach to evaluate environmental quality for 1999 and 2007 in Anyang City as well as a conceptual model of parks and greens satisfaction. This study relied on an empirical study method including the 1999 and 2007 green conditional survey and citizen questionnaires totaling 573 in the year 1999 and 982 in the year 2007. As a result, first, the factor 'urban parks' is the most important factor and 'cityscape' is the second most important factor in parks and greens satisfaction(PGS). Second, PGS in turn causes environmental quality satisfaction(EQS), which is related to two items--'urban livability' and 'aesthetic quality'--in the model. This means that PGS is the intervening variable of urban livability. Third, the factor analysis resulted in six factors: cityscape, urban green, linear facilities, urban parks, riverside green, and urban forest. 'Riverside green' emerged as a factor in 2007 as a result of public participation in the 'Anyang River Revitalization Project'. Fourth, through a transactional view, the environmental changes result in either a change in or stability of public attitude. The levels of satisfaction were elevated but patterns of satisfied-unsatisfied items remained unchanged for most factors. The perception of riverside a greenway and linear surface facilities(pedestrian walkways, biking and jogging trails, etc.) have changed positively. PGS changed significantly in 2007, as a result of urban events and development, including parks, rivers and greenways which were built through the joint effort of the local government and civic participation.

This study focuses on Abstract Types in Contemporary Landscape Design. The formation and artistry of contemporary landscape design reveals many areas which Previously have not been able to be expressed in scenic landscape thanks to the deviation of the genre in contemporary landscape and the hybridization that has occurred among architecture, landscape and art genres. The focus of this study is basic research concerning "the abstract", which is used as a creative artistic theory in a variety of art fields such as landscape, architecture and painting. Through a theoretical establishment of "the abstract", its process of change, and the discovery of its contemporary principles, the relationship between each art field in landscapes and the formation of the abstract, abstract language, and abstract properties have been studied. The use of the abstract in contemporary landscape design can be classified in three ways: Inductive abstract representing conceptual transcendental symbols not logically but rather through intuition and transcendental cognition to display the inner expressions, ideas and minds of the artists. Second, a deductive abstract represents an expansive, logical model for the simplification of objects, distortion, exaggeration based on knowledge and logical reasoning about objective fact based on traditional realism. The complexity of the abstract is a concept that is bound to both the deductive & inductive abstract. As a major trend, the concept of "The abstract" in contemporary landscape has been putting forth ever-deeper roots. New trends like abstract works and landscape architecture reflecting the artist's inner expression, in particular, will provide fertile soil for landscape in the future. Further research about the concept of "the abstract" will also be necessary in the time to come.
