Park, Eun-Jin ; Kang, Kyu-Yi ; Lee, Hyun-Jung ;
Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 1~10
The study was aimed at analyzing the relationship between the characteristics of urban green infrastructure and stormwater runoff in a small urban watershed composed of 22 drainage basins. The green areas of which soils are not sealed and allow water infiltrate, were examined for different types of green spaces. In a comparative study for drainage basins of which green spaces are 15.5% and 34.4%, respectively, runoffs were not different with the size of green space. It was attributed to that the increase of runoff by greater road area offset the advantage of greater green area. Another comparative measurement of runoff for drainage basins with similar green area size showed that runoff decreased with greater permeable area (school ground area) and smaller road area. The runoff measurements could address that runoff rates are affected not only by green area size but also by the type of green area and other land covers related to permeability and flow into drainage. It implicated that the improvement of urban green infrastructure as a functional unit for water infiltration and interception is important for stormwater runoff management.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 11~25
In broad agreement on the need for forests in the city, researches on the urban forest are being actively carried out. Nonetheless, since these researches focus on functional usage within living spaces, finding methods for creation of urban forests and technical solutions have remained chief issues as a consequence. This paper, which attempts to historically examine the properties of the urban forest within living space, has the characteristics of researching basic angles for approaching the creation of contemporary urban forests. For this purpose Joseon Dynasty genre paintings, which represent living conditions of Joseon era, have been decided as theme of the paper. Particularly the focus was limited to genre paintings depicting trees, giving phenomenal observations. As a result, some remarkable characteristics emerged as functional urban forest, symbolic urban forest, topological urban forest, and appreciative urban forest. Urban forest within living space mainly appear as functional, showing an even distribution in small numbers rather than gathering in large groups. The following can be inferred regarding this and related to the setting up of the scope of, and creating of, contemporary urban forest : First, from the viewpoint of urban forest creation there is a need to study more subdivided and refined types of the urban forest and to actually realize these types. Second, from the viewpoint of urban forest usage, one needs to approach existing forests, ranging from small-scale including invididual trees, to mid-, large-, and super scale, as urban forests. In this, a network of major trees, and thereby a matrix of all trees formed by that network, will be formed. Third, from the viewpoint of urban forest improvement, approaches need to be based on planting trees in even distribution across the whole city.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 26~37
The purpose of the study was to evaluate the effect of pervious pavements on reducing the surface runoff caused by rainfall. The surface runoff from twelve steel experimental beds with different pavement had been recorded every minute from May to September 2008, by the measuring system of tipping buckets(0.1mm/count) and data aquisition systems(National Instrument's Labview and DAQ boards & Autonics PR12-4). The dimension of the experimental bed was
and eleven different kinds of vegetational(grass, grass+cubic stone, grass+hole brick), modular(brick, cubic stone, small cubic stone, wood block, interlocking block, clay brick, granular clay brick) and granular(naked soil, gravel) paving materials and concrete were applied for the comparison. Six rain events with depth over 30mm were selected and compared. The maximum depth of the rainfall selected was 137.5mm for 28 hours, and the minimum 30mm for 5 hours. The maximum rainfall per hour was 23mm/hr and the minimum 11.4mm/hr. The major findings were as follows; 1. All pervious pavement applied reduced over 75% of the surface runoff compared with concrete pavement. The grassy and porous pavements were relatively efficient in reducing surface runoff. 2. The grass was the more efficient as intercepting average 69.5mm of initial surface runoff, and maximum 77.8mm at the condition of 13.5mm/hr rainfall. The next was gravel intercepting maximum 65.5mm at the condition of 13.5mm/hr and the 40.9mm at 19.1mm/hr, average 55.7mm. 3. The modular pavements common in urban area were not good in intercepting the runoff except the 'clay granular brick' compared with others. The 'clay granular brick' showed relatively efficient intercepting average 14.1mm, which was the bigger amount than the 'grass+hole brick'. 4. The 'naked soil' were more effective than the 'concrete', 'brick', and 'interlocking block' in reducing the surface runoff, but less efficient than other materials. The capacity of the 'naked soil' to intercept the initial rainfall was similar to the 'brick'. As summary, the more grassy and porous pavement shows more effective in reducing surface runoffs.

Visual Characteristic Assessment of Sidewalk According to Street Planting Types - Focus on Sidewalk in Daejeon Metropolitan City -
Jeong, Dae-Young ;
Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 49~60
In this study, the green zone patterns of sidewalks are classified 'one street-tree row + building,' 'one street-tree row + green zone,' 'two street-tree rows + building,' and 'two street-tree rows + green zone' and assessed their visual characteristic in order to provide desirable measures for scenery design. As a result of the analysis of visual images of sidewalk, the scenery in which street trees are planted in one row was generally assessed to be negative, while roads where green zones rather than buildings are adjacent were revealed to seem stable and pleasant. The scenery in which street trees are planted in two rows was assessed highly in an image of 'extensionality' indicating street circumstances, and especially the pattern 'two street-tree rows + green zone' was shown to be the most beautiful scenery. According to the results of factor analysis of sidewalks, three factors were identified : 'extensionality' showing sidewalk circumstances; 'peculiarity' including unique personality, and 'pliability' showing the organic flow of the scenery. The results of the analysis of visual preference of the scenery according to green zone patterns showed that the 'two street-tree rows + green zone' was measured to be highest. When buildings are adjacent to a sidewalk, two street-tree rows rather than one street-tree row were assessed to increase preference. As for the correlation between visual factors and preference analyzed through multiple regression analysis, all 'extensionality,' 'peculiarity,' and 'pliability' were revealed to show positive correlation for visual preference.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 73~80
This research investigated appropriate indoor light sources and light intensities for Hedera rhombea and Saxifraga stolonifera, which are shade-tolerant and cold-resistant indoor plants. Plants were grown in wood flames of 1 m in width
1 m in length
1 m in height. Light sources were fluorescent lamp, three wave fluorescent lamp and halogen lamp that are being used in most of the subway stations in Korea, and light intensities were 200 Lux, 700 Lux and 1,000 Lux. Results are as following. 1. Hedera rhombea Hedera rhombea heights did not show differences statistically as responses to light sources and light intensities. It, however, tended to be greater with an order of 1,000 Lux, 700 Lux and 200 Lux and halogen lamp, fluorescent lamp, and three wave fluorescent lamp. Number of branch increased under fluorescent lamp than under halogen lamp or three wave fluorescent lamp, and increased under higher light intensities. Number of leaf was higher with an order of three wave fluorescent lamp 1,000 Lux, fluorescent lamp 1,000 Lux and halogen lamp 1,000 Lux. Leaf shape became wider under low light intensities regardless of light sources. Chlorophyl contents in leaf were not significantly different under three wave fluorescent lamp and halogen lamp. However, the contents increased with an order of 200 Lux, 700 Lux and 1,000 Lux under fluorescent lamp. 2. Saxifraga stolonifera The plants were dead or declined under fluorescent lamp regardless of light intensities. When light intensities went under 200 Lux, Saxifraga stolonifera showed poor growth for all the light sources. Plant height, number of shoot, number of leaf, leaf width and leaf length have increased with an order of halogen lamp 1,000 Lux, three wave fluorescent lamp 1,000 Lux and three wave fluorescent lamp 700 Lux. Chlorophyl content was greater with an order of three wave fluorescent lamp 700 Lux, three wave fluorescent lamp 1,000 Lux and halogen lamp 1,000 Lux.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 81~90
Recently, geofiber(polyester) reinforced soil was added on soil-seed mixture spray to control erosion and to improve vegetation growth on rocky slope sites. This research was conducted to compare vegetation effects and soil hardness on three types of soil-seed mixture spray on stone gabion river bank [A type : soil-seed mixture spray underlying 30cm thick sand with geofiber(geofiber reinforced soil system), B type : soil-seed mixture spray underlying 30cm thick sand without geofiber, C type : soil-seed mixture spray]. Evaluation were made concerning vegetation coverage, soil hardness and moisture content. The results of this study showed that A type system was effective for the growth of vegetation and soil hardness when compareed to B type and C type. A type and B type showed higher covering rate than C type on stone gabion river bank, and especially A type showed the highest covering rate. Soil hardness and water content were high on A type vegetation system compared to B type and C type. We noted that high soil hardness and high moisture content with geofiber(geofiber reinforced soil system) were effective both to control erosion from water current impact and to be high coverage and species of vegetation on stone gabion river bank.

Joo, Shin-Ha ;
Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 91~103
The purpose of this study is to compare the satisfaction of the urban parks and to classify and assess the environmentally-friendly behaviors in the urban parks. For this purpose, the park user's behaviors and satisfactions were surveyed in 10 parks in Seoul and its suburb area. Parks are divided into 2 types, the walking-distance parks and the metropolitan parks, by time to reach, visit frequency and visit purpose. The park users are generally satisfied with the facilities, but not satisfied with some specific items, such as cultural facilities, accommodations for the handicapped, safety facilities and sports facilities. The environmentally-friendly behaviors are positively assessed in general, but the behavior of the natural experience was negatively assessed. The environmentally-friendly behaviors in the urban parks are classified into 2 factors; the experience factor and the activity factor. The parks are categorized into 3 types by these factors. For type I parks, the experience factor is dominant, but the activity factor is relatively low. For type II parks, the both factors are low and the parks are necessary to improve. And type III parks are positively assessed in the aspect of the environmentally-friendly behaviors, even though some park are necessary to complement.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 104~111
Plant growth and variegated leaf color changes of three leaf variegated Sedum spectabile varieties 'Variegatum', 'Frosty Morn', red colored 'Washfield Ruby', and one Sedum lineare variety 'Variegatum' and Sedum sarmentosum under three levels of shading conditions were examined for leaf ornamental value improvement. Shading levels were 40%(
) and 85%(
). Improvements of leaf ornamental value of 'Variegatum' 'Frosty Morn' and 'Washfield Ruby' were observed at 40% shading level and plant heights and leaf sizes were also increased. Plant height of S.sarmentosum were shorten under direct sun light condition and leaf color changed to greenish yellow(RHS143B) but deep green color(RHS144A) was observed under shading conditions. Endurance of S.sarmentosum was stronger than other species and leaf ornamental values remained well at 70% shading level. Leaf width of S.lineare 'Variegatum' were not changed under shading conditions but leaf length was increased. Leaf color was Deep green color was greenish yellow under direct sun light but deepest green color was observed at 85% shading level. Consider all ornamental value criteria, best shading conditions for S.lineare 'Variegatum' were ranged 40% to 70%.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 112~119
In order to elucidate growth characteristics, physiological responses and leaf color changes of Physocarpus opulifolius 'Diabolo' and Ophiopogon planiscapus 'Nigrescens'. These experiments were investigated under various shading levels. Growth of P.opulifolius 'Diabolo' was better at 30% shading level but physiological activities were double at strong light condition. Dark purple color was observed at 85% shading level and color was dim down when shading level decreased. Color was deep purple(RHS 202A) at 85% shading and green(RHS 139A) at 0%, These results imply that ornamental value was increased when shading level increased for P. opulifolius 'Diabolo'. Growth and highest physiological activity of O. planiscapus 'Nigrescens' were observed at 0% shading level and dark red color(RHS 202A) was also observed at 0% shading level. These results imply that ornamental value was increased when shading level decreased for O. planiscapus 'Nigrescens'.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 120~129
Removal rate of
and TN in a free water surface wetland system with litter layer on its bottom was compared with that without one. The system was established on floodplain in the down reach of the Gwangju Stream in 2001. Its dimensions were 31 meters in length and 12 meters in width. Water of the stream was funneled into it and its effluent was discharged back into the channel. Average litter layer of 9.6 cm was formed on its bottom in 2007. The layer and above-ground parts of reeds and cattails on the system were eliminated in Spring 2008. Volumes and water quality of inflow and outflow of the system were analyzed from May to November in 2007 and 2008, respectively. Inflow into the system both in 2007 and 2008 averaged approximately
and hydraulic residence time both in 2007 and 2008 was about 1.5 days. Average influent
concentration in 2007 and 2008 was 2.16 and 2.05 mg/L, respectively and influent TN concentration in 2007 and 2008 averaged 3.98 and 3.89 mg/L, respectively. With a 0.05 significance level, effluent temperatures, influent concentrations of
and TN, and stem numbers per square meter and height of the emergent plants showed no difference between the system with litter layer and without one.
removal in the system with litter layer and without it averaged 55.59 and 46.06%, respectively and TN retention averaged 57.24 and 48.97%, respectively. Both
and TN abatement rates in the system with litter layer were significantly high (p < 0.001) when compared with those without one. The wetland system having litter layer on its bottom was more efficient for
and TN retention than that without one.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 130~142
The objective of this study is to analyze the types and current status of development projects that underwent environment assessment in recent three years and provide basic data to encourage environment-friendly development projects in the future. This study was conducted by analyzing the pre-environment review reports and environment impact statements of development projects that took place in Gyeonggi province. Key findings are as follows. First, a total of 2,465 development projects spanning
were undertaken in Gyeonggi province in recent three years. This is equivalent to three times of the area of Anyang city. Second, types of development projects were in the order of factories and industrial parks, road construction, town (housing estates) development, sports facilities and waste treatment facilities. Public projects accounted for about 30%, while private investment projects represented 70%, indicating that private sector projects were as twice as high. The findings of this study show that the development density of Gyeonggi-do should be examined as a whole in order to develop a comprehensive, long-term plan and harmonize conservation and development systematically in Gyeonggi-do in a holistic perspective.

Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 6, 2008, Pages 143~152
A comparative analysis of rooftop greening in Korea and Japan was carried out to understand current status of rooftop greening creation and technology and to give directions to frame a policy or plan on rooftop greening in Korea. Besides literature studies, questionnaire survey to Korean and Japanese experts on rooftop greening were done. As results, the annual creation areas, the types and the scales of rooftop greening in Seoul and Tokyo until 2007 were analysed and the satisfaction on the creation areas and technologies, the preference types, the present levels of and the most important parts among policies (support systems), technologies (creation methods), materials, maintenances and user programs for the development or expansion of rooftop greening in Korea and Japan were compared. The creation areas of rooftop greening in Seoul until 2007 was around 15% in Tokyo but the increasing rate of those in Seoul was faster than in Tokyo. Korean needs for the improvement on the rooftop greening systems and technologies were higher than Japanese, but both desired the expansion of rooftop greening areas in both countries. Korean preferred semi-intensive rooftop greening system but Japanese preferred intensive system. Korean and Japanese rooftop greening experts preferred policies (support systems) and technologies (creation methods) for the most important part for the development or expansion of rooftop greening in both countries.
