Journal of the Korean Institute of Landscape Architecture, volume 33, issue 6, 2006, Pages 1~11
The purpose of this study was to investigate the influence of natural landscapes in the context of work environments. The study examined the impact of natural landscapes on urban office workers' stress reduction and cognitive performance, using physiological, psychological, and cognitive measures. One-hundred-twenty urban office workers participated in the experiments. The physiological measures used were GSR (galvanic skin response) and IBI (interbeat interval), and the psychological measure was ZIPERS (Zucherman Inventory of Personal Reactions). Cognitive performance was measured using a mental arithmetic test that had been developed by a pretest. The results from the physiological, psychological, and cognitive measures converged to indicate that the natural landscape had more beneficial effects in relieving both psychological and physiological stress and in enhancing cognitive performance of the of office workers than the city landscape. The results suggest wide applications in the fields of workers' well-being and landscape research. First, the results can provide reliable information for promoting natural landscaping in work places in order to relieve worker stress and enhance cognitive performance. Second, the results provide an example for future empirical landscape research using multiple measurements, such as psychological, physiological, and cognitive tests. Third, they can foster experimental research to investigate the relationship between stress reduction and natural landscapes.

This study aims to examine what factors park users value in urban natural parte and to find ways to elevate user satisfaction for the creation and usage of an urban natural park To achieve this, the study relied on two methods: the descriptive method of researching publications and related scholastic writings, and the empirical study method including a survey of present condition and interviews with users. 'Breathing fresh air' and 'cleanliness' were the most important items and play facilities, cultural facilities, and landscape facilities were of lower orders of importance. This suggests that the 'sense of nature' is more important than functional facilities in urban natural parte. The importance of urban natural parks and the satisfaction visitors felt in them were measured, with mean results of 5.86 and 3.88, respectively, in terms of living surroundings. The impotance rating is higher than the satisfaction rating. Factor analysis resulted in six factors: benefits sought facilities for use, pleasant use, safety, accessibility, and management. Correlation and regression analysis showed only one positively correlated factor: benefits sought, suggesting that people recognize the importance of urban natural Parte through the benefits they gain in them and the satisfaction they find in urban parte depends on utilizing facilities. Therefore, in urban natural parks, people will find greater satisfaction through pursuit of the benefits they are seeking; improvements to park facilities should address the benefits that park users are seeking.

This paper is the study on the activity of citizen participation in the movement of Million Amenity Park's creation which was proposed by citizen participation for large scale's flat park within city. This park was proposed by the Busan Green Plan, commission study in 1999. The location of Park site was finally proposed at Dunchi-do, Bonglim-dong, Gangseo-gu, Busan and neighbor areas. The area of park site is approximately 500ha included the surface area of West-Nakdong River. Citizen's organization for Million Amenity Park which has 3,500 members, was established in 2001 in order to compose Million Amenity Park The development processes of this study were found to have quickening period, germination period, the 1st growing period, and the 2nd growing period, and then the results of this activity was also arranged by the researcher of this study. The movement for this park was found to have a positive activity for participating and understanding all the citizens during 7 years. And then the activities for this park were as follows: every information, fund-raising campaign, organization, purchase of park site, contribution of purchasing park site to Busan city. The results of this study, through the movement of citizen's participation such as this park movement were 1) respectively found to have the settlement in the movement of NGO, 2) the possibility of large scale's park fostering by public and civil partnership, and 3) the model presentation of frontier park in the citizen participation's types which will be able to introduce the development of city.

Journal of the Korean Institute of Landscape Architecture, volume 33, issue 6, 2006, Pages 40~50
This study was carried out to examine the tree-ring growth characteristics of Zelkova serrata Makino after replanting, for the built-up planting founds for stability of landscaped trees in the reclaimed land from the sea. the factors, many affecting the growths of Zelkova serrata Makino, were the replanting stress and drought. The growth reduction due to replanting and drought occurred in the replanting year and the following year. The mean sensitivity(year-to-year variation) and the coefficient of variation(tree-to-tree variation in a certain year) in tree rings of Zelkova serrate Makino, were higher in the poor soil sites than in the favourable soil ones. And the poor soil sites were the filled ground of improve soil and the covered ground of improve soil and the top ground of big mounding than mounding ground sites, especially soil hardness, alkali soil, high
and T-C were the most crucial. We suggest technique development of the built-up planting ground for stability in the reclaimed land from the sea. The built-up planting grounds in reclaimed land from the sea, should be considered for the use of fair soil with the physical and chemical soil properties, -high level foundation of planting ground, and the prevention of disturbed soil-.

Pond management is a critical part of overall golf course management, both during growth and maintenance modes of turf care. This study investigated 48 ponds in nine 18- or 27-hole golf courses to analyze the environmental characteristics of ponds. The research process had three phases: (1) inventory and analysis of grading plans and drainage plans, (2) field verification and interviews with greenskeepers, and (3) analyses of water quality and statistics. All data were collected from May to August in 2004. The results of this study can be summarized as follows: 1. It is desirable to site a golf course in a small watershed with high watershed eccentricity to control storm water runoff efficiently and to minimize soil erosion during construction. 2. The siting and size of a pond should be determined through a land-use analysis of the watershed for the purpose of ecological management. The bigger the forest-to-golf course ratio, the better the water quality will be. 3. The size and capacity of each individual ponds varied and there were many somewhat longish rather than round ponds. 4. There were many differences among golf courses in naturalness of the ponds, and the correlation between naturalness and area of aquatic plants was very high. 5. Analyses of pond water quality indicated that the degrees of Dissolved Oxygen, Chemical Oxygen Demanded and Suspended Solids were relatively low values but Total Phosphorus and Total Nitrogen were too high. Therefore a systematic approach is needed to solve e problem. Pesticide residues were not detected in all ponds. 6. Water depth and area of hydrophyte should be considered when designing an ecological pond. 7. All ponds used storm water as a main source of water supply and added underground water. Aquatic plants and physical methods such as water aeration and spray fountains were the main choices for maintaining a healthy aquatic environment.

This study was conducted to analyze the planting structure and ecological characteristics of greon spaces on the grounds of e Dangjin steam power plant. To achieve these goals, we surveyed existing vegetation, plant community structure, Plant volume and growth rate. Based on e vegetation analysis, existing vegetation was classified into six types: herbaceous species
, evergreen coniferous trees
, deciduous broad-leaved trees
, deciduous coniferous trees
, and other types
. The coal storage, office, and playground areas were community is the natural forest area where a Pinus thunbergii / Pinus densiflora community is distributed in terms of vegetation structure, species diversity, plant volume, and growth rate. The artificial green spaces(near the coal storage, office, playground areas) had a single-layer structure. Species diversity indices of the artificial green areas were
compared to 0.8628 in the natural forest, which presented a good growth environment. Also, the plant volume in the artificial green space was lower than that of the natural green space. Therefore, it would be desirable to develope a multi-layer structure similar to that of the vegetation in the natural green space in order to improve the amount of plant volume. The plant-damage ratio of Pinus thunbergii was
in the coal storage area, and
, in the other survey areas. Also, the vitality of Pinus thunbergii was
in the coal storage areas, which indicates bad growing conditions. This suggests that soil characteristics and dust have a bad impact on growth. The investigation into deciduous tres' growth status showed that appropriate plants would be Albizzia julibrissin, Acer palmatum var. sanguineum, Acer palmatum, Malus spp., Prunus sargentii.

Journal of the Korean Institute of Landscape Architecture, volume 33, issue 6, 2006, Pages 90~97
The effects of a green buffer zone to protect a residential area from air pollution from industrial facilities and traffic was examined by analyzing the case of a green buffer zone in the Shiwha industrial complex. The green buffer zone is 175 m wide. The intent was to assess the dispersion patterns of atmospheric air pollutants and the reduction in concentration around the green buffer zone. To measure atmospheric sulfur dioxide
and nitrogen dioxide
concentration, badge-type passive samplers were used and set up at 76 locations in order to measure the concentration of air pollutants with respect to the spatial dispersion. The weighted mean values of
and the differences among the green buffer zone, the industrial area and the residential areas were
. Mean values of atmospheric concentrations of
were similar in industrial and, residential areas and the green buffer zone. Results of the study show that the effect of the green buffer zone on reducing the dispersion of air pollutants was very low. This study also recommends that micro-climate, i.e., wind direction should be considered as a factor for planning and design of green buffer zones.

The climate of urban area is an unstable type with considerable seasonal variation in precipitation wind speed, and temperature and it grows worse. Besides, ozone is a serious air pollutant in most of large cities. So worldwide, some of large cities are investing in forestry options to offset their climate problems, but lack of information has hindered comparisons of urban un cost effectiveness to other options. This research intends to study the economic benefits of tree shading of 19 parking lots in UCD campus. The economic benefits of tree shading are air conditioning savings, air quality, stormwater run-off, and other benefits. Especially, this study focuses how much the economic benefit of parking lot shading has been increased from 1995 to 2003 year by aerophoto. Some data on dimensions of parking lots and the number, size, tree species, and location of trees around each parking lot was inventoried. Two aerophotos(1995,2003) were used in order to analyze the increasement of tree canopy in 19 parking lots for 8 years. However, increasing coverage of trees and managing them for healthy growth would not be sufficient for avoiding adverse impacts by future climate change. Additional measures should be followed such as an increase of energy use efficiency and development of substitute energy. For example, coverage of trees help to save cooling energy by blocking solar radiation reaching parking cars and building structures through shading, and creating cool micro-climates through evapotranspiration. They also reduce heating demand by decreasing air infiltration and heat conduction out of the interior of buildings. Proper arrangement of vegetation over the parking lots can reduce cooling and heating costs. So proper planting design around hard space paving including species selection and location can significantly save cooling and heating energy. And a reduction in car and building's heating and cooling costs results in the reduction in energy demand which causes to emissions of air pollutants. Total increased tree canopy from 1995 to 2003 is
and the economic benefits is US$ 5,282.10. The economic benefit of one tree has been US$ 7.21 for 8 years. And an annually increased benefit is US$ 0.9 per a tree. If this kind of study is applied to studying the economic benefits of tree canopy in parking lots of Korea, it could result in guidelines of tree planting of parking lots. Because the trees selected for planting in parking lots were not suitable for an environment, the guidelines should contain a recommended list of trees. The guidelines should propose the shading percentage of parking lot when we plan a parking lot and contain the maintenance of trees in order to maximize the economic benefits of tree canopy.

As the national interest in sports has been increased over time, sports facilities and sports complex are considered more than just physical environments for training athletes or watching games. Sports facilities now become symbolic spatial devices to represent the national and cultural pride of any countries. The existing national training camp located in Taenung, Seoul is gotting outdated and degraded. The polluted air in the city risks athletes' health condition. The government planned to construct the second training camp at Jincheon, Chungbuk at the area of
. The Korea Sports Council called for proposals to envision the future training camp, and they held a design competition from August to November, 2005. The first phase was to present the masterplan for the entire site including training buildings, outdoor training facilities, dormitories, a visitor center, a research center, education and administration buildings. Considering the size of the site, the planning process required a strong relationship between landscape and architecture. This study tries to provide general explanations on the winning proposal focused on the landscape-related issues. It also attempts to have reference points for contemporary planning and design issues to situate the project in the stream of continuing design effort to avoid the dichotomy between nature and culture. The landscape proposal for the new national taming camp suggests four main strategies; 1) The camp has two intersecting and interweaving parks which represent the natural and urban order. 2) The entire site is organized and networked by the flow of landscape called landscape ribbon in terms of topography, vegetation, and water flow. 3) The landscape is choreographed through the time and process. 4) The ecological process and the digital contents are juxtaposed in the landscape. This winning proposal is the first step to portray the national vision for the sustainable environment coexisting with sports industry. Landscape in this proposal is an active agent to network various parts of the site which enables landscape to be infrastructure. Landscape design in this proposal should be considered open-ended strategies rather than determined concrete forms and its engaging further development will be tested in following Design-Build phase.

Journal of the Korean Institute of Landscape Architecture, volume 33, issue 6, 2006, Pages 127~139
Mt. Yokmang landscape design awarded first in [North container terminal site furtherance construction in Busan new port], design competition sponsoring in the Korea Container Terminal Authority in 2005. Design guideline was to propose the symbol of new port and to establish landscape plan in consideration of view and geological location. Because landscape plan required establishment of restoration plan for cutting slope, Mt. Yokmang became the major object. The purpose of planning are as follows. The first purpose is to minimize existent natural environment damage, and the second, to connect with ambit and create new image. The third is to provide place of rest and interchange for local resident. Reflecting stratum structure and landscape characteristics, cutting slope consisted of [utilization slope], [presentation slope], [landscape slope], and [ecological slope]. Vegetation design applied ecological restoration method through restoration of stratum, and eve environment-friendly afforestation, planned program that can connect area with existing ecosystem. In process that decides form of the cutting slope, analyze view structure and visual exposure in various access routes, sensitivity etc. was accomplished. Also, symbolic tower(Ocean Polaris) that presents in architecture and landscaping features, night landscape planning could gain synergy effect by keeping consistence with landscape and ecological planning. Passing through final design and construction process, I expect that the Mt. Yokmang will be a new landmark in Busan new port.
