This study was carried out to analyze the problems on several steps of the establishment of the Nature Ecological Forest in Yeouido Park, Seoul, and also to suggest improved approaches on each step. For execution drawing, planting models and plans seemed to be uncertain, and the quantity and size of planting trees seemed to be impractical. For construction, the woody plants planted on the site were different in species and size from the planting plan. Ecological planting was somewhat limited because of the inappropriate soil properties. For management, replacement of the dead trees was not executed properly, and no management scheme was prepared after the replacement period. We suggested improved approaches for the establishment of ecological forests in urban areas as follows: for execution drawing, overstory, understory and herbaceous ground cover layers should be composed based on standard plant community structures. Trees that are available from tree markets should be specified in the planting plan. For construction, trees for planting need to be tagged to identify species and size. When tree species and size are changed, they should be checked to ensure that they are proper to the plant community model. Soil information should be collected to check that they fit the target plant community model. For management, the proper amount of trees needs to be specified in the planting plan by applying regular discount rates, especially for trees supplied from the government sector. The replacement period should be extended from two years to five years. The change of plant communities should be monitored during first five years after establishment.

The purpose of this research was to find out the characteristics of secluded cultural landscapes that were retained by Eyogye Cho Lyeo(漁溪 趙旅) as a recluse or a schola at the early time of Chosun dynasty through his poems, residential site and his successors' landscapes. The study sites were selected such as Wonbukgae(院北齋), Chamijeong(採薇亭), Gomaam (叩馬巖) and his graveyard. In order to do that, Wonbukgae, Chamijeong, Gomaam and his cemetery were selected as studying sites. Also researching methods were used by grasping the landscape elements through reading ancient books such as "Eyogyezip(漁溪集)", field-researching, analyzing characters of his secluded landscapes and interpreting his poem's meaning. This research found that: 1) After Danjong(端宗)'s dethronement, he returned to his home town and never come out to the world again. He wanted to keep fidelity to his king forever. 2) He was affected for his seclusion from many people who were Ryu Gyebun(柳桂芬), Bae Junghu(裵仲厚) as his classmates at Sunggyungwan(成均館). Also Won ho(元昊) and Kim Sisyub(金時習) as members of Sangyuksin(生六臣) affected him for sake of their seclusion. 3) The meaning of his seclusion expressed the notation of seclusion as a fisherman from his pen name as 'Yeogye'. Also this kind culture has very particular behavior such as concentration phenomenon of action, absolute eccentricity of seclusion, tourism of nature and deep knoledge of feng shui, strong persistence of seclusion and confucian practical attitude of filial behavior. 4) The secluded cultural landscape is divided to four regions. They have two types of landscape such as secluded cultural landscape of his lifetime and landscape transmission of his posterity and scholars. 5) The interpretation of his poems and their aesthetic analysis found two characters. His poems were expressed by landscape substance like plants, natural and man-made elements. Their theme was confucian, peaceful and faithful seclusion.

Since walking and physical activity are critical for older adults to maintain their health, it is important to provide neighborhood environments which encourage their walking in daily life. The purposes of the present study were to investigate walking activity patterns of older people in an urban setting and to identify environmental correlates with walking of older adults. This study examined spatial and temporal patterns of physical activities, environmental barriers and motivations, satisfaction levels and demands on the physical environment. In-depth interviews with older adults over age sixty residing in Seoul metropolitan areas revealed that most respondents have a positive perception on walking in daily life, and many of them walk regularly for their health. A primary purpose of walking for older adults was exercise for health rather than transportation. The study result demonstrated that parks and trails were the most preferred places for walking by older adults, and there is an association between frequency of walking participation and access or convenience to parks, traffic safety, and street lights. Most respondents were concerned about traffic safety when they walk in their neighborhoods due to traffic speeds and unsafe streets. Lack of separate sidewalks or benches, stairs and slopes were barriers to older adults' walking habits. This data suggests that the promotion of walking behavior among older adults, some level of public health action, and community support are needed to ensure safe physical environments within communities.

The purpose of this study is to analyze the biotope characteristics of Korean cities and set up biotope type structures for Korean cities based on biotope type classification, dominant biotope type, city's human and nature environmental characteristics and cluster analysis. The findings of the study are summarized as follows: First, regarding the analysis of biotope type classification, cities showed differences in terms of the standard of biotope classification and classification hierarchy. Next, the analysis of dominant biotope types showed the type of forest represents the largest area in most cities. Moreover, a city's characteristic analysis revealed large differences between cities. As a result of cluster analysis, cities were classified into five clusters overall. First, Cluster A showed a lower population level and urbanization level. Unlike other cities, Cluster A revealed that it has the largest percentage of agricultural areas. Cluster C showed very high levels in terms of population amount and urbanization conditions was named the 'Large-sized metropolitan cities-center of forest biotope area' based on it's characteristics. The findings of this study as summarized above are considered to play an important role in enabling detailed classification and preservation of biotope types fit for the characteristics of cities and minimizing the confusion caused by different biotope mapping methods when revising and complementing biotope maps.

Urban environmental problems such as flooding, depletion of ground water, pollution of urban streams and the heat island effect caused by urban development and climate change can be mitigated by the improvement of the urban water cycle. For the effective planning of water cycle management it is necessary to establish aerial Hydrotope Maps, with which we can estimate the status and change of the water allowance for any site. The structure of the German water balance model BAGLUVA, which is based on soil and vegetation, was analyzed and the input data and boundary condition of the model was compared with Korean data and research results. The BAGLUVA Model consists of 5 Input categories (climate, land use, topography, soil hydrology and irrigation). The structure and interconnection of these categories are analyzed and new concepts and implementation methods of topographic factor, maximum evapotranspiration ratio, effective rooting depth and Bagrov n parameter was compared and analyzed. The relation of real evapotranspiration ($ET_a$)-maximum evapotranspiration ($ET_{max}$) - precipitation (P) was via Bagrov n factor represented. The aerial and land use oriented Hydrotope Map can help us to investigate the water balance of small catchment areas and to set goals for volume of rainwater management and LID facilities effectively in the city. Further, this map is a useful tool for implementing water resource management within landscape and urban planning.

The knowledge-based society of the 21st century requires a new kind of professional. Studio education has been the core pedagogical method to bridge the practical world and higher education in the field of landscape architecture. However, it is questioned whether studio classes have truly been performed from the learners' perspectives to solidify the competencies to meet the demands of the changing society. This study tries to draw key issues related to studio pedagogy in order to make a foundation for the improvement of studio classes in landscape architectural education. Five issues regarding landscape architectural studio education have been suggested through the literature review of three categories: the core competencies required for the future professionals, the pedagogical paradigm shift, and the changes along the evolution of landscape professions and curricula. The first issue is suggested as to approach the competencies from the holistic and systematic approach to define landscape architectural professionals for the 21st century. Second, studio classes should be redefined in the context of an entire curriculum, and, as a consequence, the linkage among the individual courses is found to be important. Third, design studio classes need to be restructured to have differentiated pedagogical objectives for the development of the learning phase. Fourth, it becomes crucial to research the pedagogical methodology and the reflective actions of instructors. Finally, it is required to think about what it means to be practical in the context of studio classes and the enhancement of educational infrastructure for the studio classes is to be important.

Trees, cultivated in containers, are appropriate in soil deformation such as road sites with cutting and filling. This study tested the effectiveness of trees produced in containers for early rootage in street tree transplantation. For the study, Korean Mountain Ashes(Sorbus alnifolia) were used for experimental groups. The groups were categorized into three categories: trees cultivated in containers with mulching treatment(group A), trees cultivated outdoors with mulching treatment (group B), and trees cultivated in containers with weeding treatment(group C). Each group consisted of ten trees of the same size and transplanted to the experimental site. In order to compare each group's rootage, the study was carried out with the chlorophyll fluorescence method by the analysis of photochemical reaction. As a result of the study, group B had the lowest the maximum fluorescence amount(P). The amount of fluorescence increased by OJ transition of the process, and appeared to reduce the photosystem II electron transport efficiency. In photosystem II, electron transfer energy flux through photosystem I(RE1o/RC, RE1o/CS) was also reduced by more than 20% in group B. These results may imply that transplantation of container-cultivated trees with mulching treatment provides the most rapid rootage among the groups. The weeding treatment is also more effective than mulching treatment for rapid rootage of street trees.

This study investigates how Abies holophylla was planted as a tree sacred to the gods by Japan during the late Chosun and Japanese colonial periods. This study surveyed the current conditions of old Abies holophylla geological information, year planted, and the relationship between Abies holophylla and traditional Japanese values. The reasons that Abies holophylla was considered a tree sacred to the gods are as follows. Firstly, trees are planted on the spaces between Iljumun and Numun in Buddhist temples of Korea in the same way as trees are planted on the roads for worship in traditional temples of Japan. Secondly, tree diameter at breast height ranged from 60cm to 100cm. This means that the Abies holophylla trees range in age from 70 years to 138 years, showing that the trees were planted at the period between the beginning of Japanese Buddhism(1877) and the Japanese Colonial Period (1945). Thirdly, conclusions regarding why the Abies holophylla were planted in Korean temples at the beginning of Japanese Buddhism will be drawn based on the records that Jingu-Kogo's Conquest of Silla was taken care of the Suwataisha as a tree sacred to the gods in Japanese tradition. The reason for which Abies holophylla was planted in Korean temples should be evaluated through the remnants of Japan in the past. The issue of the old Abies holophylla in Korean temples should be investigated and further discussed in depth.

Brownfield sites are beginning to be considered as potentially useful areas for landscape design and planning, with post-industrial areas such as water treatment facilities and military training bases being converted into useful landscapes such as parks and recreation areas. These redevelopments bring broad benefits through revitalizing communities and increasing property values, thus, increasing the demand for comprehensive management and planning policies. This study examines changes in U.S. brownfield policies and programs and, identifies their periodic characteristics over the thirty years since the Superfund program was introduced in 1980. A descriptive and interpretive approach was utilized, focusing specifically on a time sequential analysis of the data gathered from the overview of the Environmental Protection Agency's web-based documents and related literature. The primary changes in and characteristics of programs and policies were analyzed and divided into three periods : environmental protection, remediation and reuse, and comprehensive planning. Four major features were identified: relaxation and readjustment of regulation, diversification of support programs, a mix of top-down and bottom-up approaches, and database system building. The study examines how common brownfield problems such as site identification difficulties and assessment and remediation cost have been dealt with in the regulatory context and has implications for future policies and programs for effective brownfield planning and management in Korea.

This study analyzed the characteristics of the entries at the design competition for the Hoehyeon section of Namsan from a perspective of the Historic Urban Landscape and made suggestions from them. Hoehyeon, located at the foot of Namsan, is the most changing site in the park and Seoul City Wall. Recent excavation of the old city walls of the Joseon Era has uncovered evidence of the Japanese occupation period, making it a site where park facilities in modern and contemporary history coexist. The frame analysis has been made by the concept of the Historic Urban Landscape, the methods of approach, specialists' discussion and the guidelines of the competition. The entries were analyzed by classification of the understanding of the spatiality and cultural diversity, the recognition of the periodic layers of time, and the design implementation, the preservation, the park plan, and the future management plan. From a perspective of an Historic Urban Landscape, this study has found that each entry placed priority on the objects for preservation and suggested creative involvement and comprehensive designs for the preservation and the park plan through the understanding of the spatiality and cultural diversity and the reflection of the periodic layers of time in the designs. This study provided two implications. Firstly, there was a possibility for new recognition and the methods of approach for preservation and development. Secondly, the basic plan for the Historic Landscape should be established through research and mapping for the preservation and management of objects in Seoul having valuable historic variability. Further study for resident participation and the process by network from public to private should be taken. This study looks forward to the consideration of the direction for the design plans of places with historic and cultural value.
