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.

In recently, building greening to improve the urban environment is a very important areas. Thus, in order to promote the building greening is needed for the arrangement of its related system. In this study, analyzed the related system in Japan and the results obtained are as follows. Related system in Japan are to promote the spread of compulsory and dissemination of guidance. And to promote the spread of dissemination of guidance are to allowed a system to be included in green area of the site required, plans to loan the costs of greening, plans to subsidize the cost of greening, tax reduction and exemption, incentive on floor area ratio, plant supply and other technical guidance system. In conclusion, in order to promote the building greening note the related system of Japan and our related system should be arranged.

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.

This study were performed on roadside buffer green in Songpa-dong, Songpa-gu, Seoul in order to analyze the anion concentration according to the type of composition of roadside buffer green. Buffer green separating the physical structure of the measurement points and measurement locations were separated by roadside, green interior, the other side of the road. planting density and deposit of trees per each buffer green was measured in the order of mounding type> slope type> the plain type. If the measured temperature of the location-specific weather elements roadside> inside> the other side of the road in order of measurement and the temperature is lowered farther away from the road. If the relative humidity of the road on the other side> inside> the roadside in order to measure and this is the opposite of the temperature tendency. According to physical structure reduction of the temperature on the other side of the road and roadside in order of mounding type> the plain type> slope type was measured. As a result of measuring a anion therefore concentration of the anion inside of melt is in order of mounding type> the plain type> slope type, tended to match the melt characteristics. According to measured positions anion concentration is in the order of the other side of the road> inside> the roadside was measured. As a result of correlation analysis, in the case of measurement location-specific weather and anions the temperature is positive correlation, relative humidity is negative correlation and that`s results of previous studies were supported.

This study was carried out to suggest an appropriate plant combination by evaluating the growth of flowering ground-cover plants planted with Festuca glauca ‘Eljiah Blue’ on the roof-top environment. As for the plant materials, Allium senescens and Chrysanthemum coreanum which are shorter than Festuca glauca ‘Eljiah Blue’ and Sedum takesimense and Agastache rugosa which are taller than Festuca glauca ‘Eljiah Blue’ were selected. Festuca glauca ‘Eljiah Blue’ was planted on Conrol, and Festuca glauca ‘Eljiah Blue’ with Allium senescens (T1), Festuca glauca ‘Eljiah Blue’ with Sedum takesimense (T2), Festuca glauca ‘Eljiah Blue’ with Agastache rugosa (T3), and Festuca glauca ‘Eljiah Blue’ with Chrysanthemum coreanum (T4) were planted in each experimental plot. Plant height and covering rate were measured to evaluate the growth of Festuca glauca ‘Eljiah Blue’. Also, relative growth rate (RGR) of plant height, RGR of plant width, and mortality rate of the flowering ground-cover plants were estimated. Plant height and cover rate of Festuca glauca ‘Eljiah Blue’ was greatest in T3. RGR of plant height was greater in the order of Agastache rugosa, Allium senescens, Chrysanthemum coreanum, and Sedum takesimense. In particular, RGR of plant width was also greatest for Agastache rugosa . Mortality rates of Agastache rugosa and Allium senescens were lowest at 11%. Therefore, based on good growth of Festuca glauca ‘Eljiah Blue’ planted with Agastache rugosa, these results were suggested as a desirable combination of plant species for rooftop gardening.

본 연구는 토지피복현황과 수림의 층위구조 등이 다양한 도시녹지를 대상으로 미기상조절에 미치는 영향을 정성 및 정량적으로 파악하기 위해 녹지내의 기온 및 습도를 관측하였다. 그 데이터를 바탕으로 녹지내의 토지피복 현황과 그 비율, 녹적량과 기온 및 습도와의 관련성을 회귀분석 등에 의해 해석하였다. 그 결과 고온역은 포장면과 나지 주변에서, 저온역은 수림지 및 수면 주변에서 형성되었다. 또한, 수림(교목+소교목)으로 둘러싸인 수면, 소하천 주변에도 저온을 나타냈다. 습도는 기온분포에 거의 대응하는 형태로 고온역이 저습역이고, 저온역이 고습역으로 나타났다. 녹지가 미기상조절효과를 갖는 메커니즘은 토지피복비율의 종류, 그 비율의 차이에 따라 미기상조절효과의 정도가 서로 달랐다. 더욱이 각 녹적량의 증가는 수고에 관계없이 모두 기온은 떨어뜨리고 습도는 상승시키는 효과를 보였다. 그 효과의 효율은 교목, 소교목, 판목의 순이다. 지금까지의 실증결과로부터 고온완화에는 수림지, 수면, 초지의 순으로, 그 비율을 증가해서 배치하면 효과가 커지고, 같은 방법으로 습도의 상승에는 수면, 수림지, 초지의 순으로 그 비율을 증가해서 배치하면 효과가 높아진다. 그 효율성을 고려하면 수면, 소하천을 핵으로 그 주변은 교목 중심의 수림이 좋고, 그 층위구조는 단층림보다는 2~3층의 혼효림이 미기상조절에 미치는 효과가 크다. This study observed the temperature and humidity within the green zone to understand the effect that land coverage and the structure of forests have on the relief of micro-climate control. Based on this set of data, this study interpreted, through the regression analysis, the relevance of land coverage of the green zone with temperature and distribution of humidity, as well as the amount of green with the relief of micro-climate control. The results of the study demonstrated that high temperature regions were formed in barren areas, and low temperature regions in forests or near the water. In particular, low temperature was found in areas covered with tall and small trees, the water surrounded by forests and areas enclosing small rivers. Furthermore, mechanisms causing low temperature were, among others, the ratio of land coverage (forest, grassland, water). In fact, the temperature reduction effect varied in accordance with the types and ratios of the land coverage. Humidity also showed a close correlation with the distribution of temperature high temperature areas had low humidity and low temperature areas had high humidity. Such a phenomenon.
