N/A In order to investigate relation between park scale and temperature decrease in and near parks, temperature distribution was observed and was analyzed in four parks of different scales. Relation between the temperature decrease and ratio of green coverage was also analyzed by using regression analysis. Lower temperature was observed in and near the parks and larger cooling effect was implicated near the larger parks. The result of regression analysis showed that the increase of green coverage ratio leads the decrease of the temperature in the parks. The degree of the temperature decrease varied according to the types of the coverage.

본 연구는 수도권매립지 주변 건설폐기물 중간처리업체 내에 적재되어 있는 건설발생토의 유해물질 함량과 토양오염도를 측정하여 환경식재기반으로서의 활용 가능성에 대해서 검토하였다. 본 연구에 사용된 건설발생토의 유해물질 함량은 분석항목 모두 지정폐기물에 함유된 유해물질의 기준치 이내로 나타나 환경식재기반으로서의 재활용 가능성이 높은 것으로 나타났다. 토양오염도도 분석항목 모두 토양오염 우려기준을 초과하지 않는 것으로 나타났다. 잔디생육실험에 있어서도 건설 발생토는 식생토사로서의 활용 가능성이 있는 것으로 나타났다. This study was carried out to evaluate the recycled waste soils from construction site for using vegetation media. The concentrations of Cd, Pb, Cr??, As, Hg, Cu, Cn, organic P, TCE, and PCE were measured at recycled soil piles of an industrial waste treating company in the Metropolitan landfill area. The concentrations of polluted materials did not exceed to the standard critical levels of soil pollution in all analyzed items. The results suggested a high potential of recycling of the wastes soils for vegetation soil media. However, Cd and Cr?? almost reached the critical levels by the time of sampling, and it is necessary to develop a skill to lower concentrations of those pollutants. In the turfgrass test, the recycled soil did show an encouraging result as vegetation media in the early growth stage of perennial ryegrass.

윤용한,박헌,Yoon, Yong-Han,Park, Heon 한국잔디학회 2002 한국잔디학회지 Vol.16 No.1

본 연구는 녹지의 계층구조 등이 다양한 도시녹지를 대상으로 그 산출방법이 습도변화에 미치는 영향을 정량적으로 파악하기 위해 녹지내의 습도분포를 관측하였다. 그 데이터를 바탕으로 녹지의 토지피복현황과 습도분포, 식재의 산출방법과 습도, 식재의 계층구조의 산출방법과 습도와의 관련성을 회귀분석 등에 의해 해석하였다. 그 결과, 토지피복현황뿐만 아니라 녹지의 산출방법이 습도변화에 많은 영향을 미치고 있다. 또한, 식재율(평면적) 및 식재량(입체적)의 증가는 습도상승에 효과적이다. 더욱이 계층구조가 다양한 식재를 대상으로 그 산출방법과 습도상승과의 관계를 회귀계수와 상관계수를 통해 비교하면, 식재를 산출할 경우에는 평면적인 방법보다 입체적인 방법이 습도상승에 미치는 효과(수치)가 컸다. 앞으로 습도상승효과의 지표로서 식재의 산출은 입체적인 방법의 활용을 제안한다. For this study grasp quantitative humidity variation with planting stratification to various green space of calculation method, observed humidity distribution in the green space. with this data, coverage condition and humidity distribution, planting calculation method and humidity, planting stratification calculation method and humidity, analyzed by revolution analysis. In this result, as well as coverage condition, planting stratification effect humidity variation. increasing planting ratio (area) and planting volume (capacity) effect higher humidity. especially, if we compared between planting stratification calculation method and higher humidity, effect by a revolution coefficient and a correlation coefficient, effect relatively planting volume (capacity) higher than stratification ratio (area). today, in the index of higher humidity, planting calculation propose application of capacity method.

녹지의 배치와 식재형태가 열환경저감효과에 미치는 영향

윤용한(Yong-Han Yoon) 한국잡초학회·한국잔디학회 2003 Weed & Turfgrass Science Vol.17 No.4

본 연구는 녹지의 배치와 식재형태가 기온저감효과에 미치는 영향을 파악한 결과 다음과 같은 점이 밝혀졌다. <br/> 1) 녹지의 기온분포도로부터 고온역은 주변시 가지에서, 저온역은 각 녹지내의 식재지주변과 소하천주변에서 확인되었다.<br/> 2) 녹지의 배치와 기온과의 관계를 보면, 저온역은 각 녹지와 거의 일치하고 녹지간 시가지 및 풍하쪽에도 저온역이 형성되었다. <br/> 3) 녹지간 시가지와 기온과의 관계를 보면 저온역은 풍하쪽 시가지뿐 아니라 녹지간 시가지에서도 나타났다. 또한, 풍상쪽에 녹지가 존재하지 않은 경우에도 녹지간 시가지는 주변시가지보다 낮은 기온이었다. <br/> 4) 토지피복비율과 기온에서 식재지, 초지 및 수면이 증가하면 모두 기온저감에 효과적이고, 나지의 증가는 기온상승에 효과적이다.<br/> 5) 교목, 소교목의 순으로 그 그루의 증가는 기온저감에 유효하게 관련되어 있는 것이 파악되었다. Temperature lowering effects varied by the arrangement and types of vegetation The effects of the arrangement and types of vegetation on lowering temperature have shown following results.<br/> 1) The temperature range of a vegetation shows that a higher temperature was recorded near urban towns while lower temperature was observed around the vegetation area and small streams.<br/> 2) The relationship between the arrangement of a vegetation and the temperature indicates that the lower temperature area matches with each vegetation area. Streets between vegetations and the lower end of the wind area have also lower temperature.<br/> 3) The relationship between inter-vegetationstreets and the temperature indicates that the lower temperature area has been observed not only at the streets of the lower end of the wind but at the streets in-between streets as well. Even when there's no vegetation area from which the wind blows, inter-vegetation streets showed the lower temperature.<br/> 4) With land coverage ratio and the temperature, the increase of planted areas, grass areas, and water level have positive effects on lowering the temperature while bare areas increase it.<br/> 5) From arbor to sub-arbor, the increase of trees has a significant effect on lowering the temperature of nearby area.<br/>

This study analyzed weather characteristics for each biotope type and influential factors on outdoor temperature in the summer when thermal contamination is at its worst targeting Daedoek-gu, and suggested a management plan in thermal comfort aspect by using a bioclimatic chart. Impermeable area ratio for each biotope type was shown in orders of industrial area biotope(94.80%)>commercial area biotope(92.20%)>low floor residential area biotope (85.75%)>high floor residential area biotope(76.02%)>river biotope(2.35%)>forest biotope(0%). Meteorological element analysis was divided into daily maximum and daily minimum and conducted, and outdoor temperature, humidity, wind speed, globe temperature, and surface temperature were measured. Outdoor temperature at the daily maximum temperature was shown in orders of industrial area biotope(36.3℃)>commercial area biotope(35.5℃)>high and low floor residential area biotope(34.8℃)>river biotope(33.9 ℃)>forest biotope(30.4℃). Low humidity was created at high temperature region and high humidity was created at low temperature region, there was no special tendency in wind speed but it contributed to creation of outdoor temperature, and surface temperature and globe temperature were measured as same tendency as outdoor temperature. Outdoor temperature at the daily minimum temperature was shown in orders of commercial area biotope(27.5℃)>industrial area and low floor residential area biotope(26.9℃)>high floor residential area biotope(26.5℃)>river biotope(26.6℃)>forest biotope(26.4℃), humidity was over 80%, and globe temperature was low temperature region with lowest value at forest biotope(26.8℃) and river biotope(26.7℃) that have strong wind speed. As a result of understanding the level of affecting creation of outdoor temperature for each land cover type, impermeable cover area showed positive correlation(correlation coefficient of 0.608) for increase of outdoor temperature, and tree planting area had negative correlation(correlation coefficient of -0.694). It was analyzed surface temperature (correlation coefficient of 0.821) and globe temperature(correlation coefficient of 0.790) had high interrelationship with change in outdoor temperature. Based on this, this study suggested expansion of green and water permeable cover, inflow of air current, and application of a planting method that considered wind corridor as a means to enhance comfort for each biotope type.

This paper presents a development and evaluation of a spring type tensioning device for Korea railroad. The wheel type tensioning device used in the Korea railroad requires much time and labor for maintenance including wire replacement and oil application. So, we found it necessary to develop a new type of maintenance-free tensioning device. In this paper, we introduced a spring type tensioning device for Korea railroad.
