본 논문에서는 2차원 경계요소법 수치모형을 이용하여 급경사에서 고립파의 처오름과 진행과정을 연구하였다. 먼저 수치모형을 상대적으로 완만한 경사에 적용하여 처오름 높이를 산정하여 기존의 수리모형실험의 결과, 수치해 및 해석해 등과 비교하여 수치모형의 정확도를 검증하였다. 경계요소법에 의한 수치해는 전체적으로 기존의 자료 등과 잘 일치하였다. 다음에 수치모형을 급경사 지형에 적용하여 처오름 높이를 산정한다. 경계요소법은 완경사 뿐만 아니라 급경사에서도 고립파의 최대 처오름 높이 산정에 매우 효율적이며, 경계요소법에 의한 결과는 인공수로의 제방 또는 방파제의 설계에 이용될 수 있을 것이다. 마지막으로, 급경사에서의 고립파의 파고를 계산하여 Green의 법칙에 의한 결과와 비교하였다.

This study was carried out to find out the effect of cool-season turfgrass overseeding onto zoysiagrass(Zoysia japonica L.) for extending green color and solving traffic problem during dormant periods. Overseeding rates of cool-season turfgrasses were $10g/m^2$ of Kentucky bluegrass(KB1), $20g/m^2$of Kentucky b1uegrass(KB2), $60g/m^2$ of perennial ryegrass(PR), $80g/m^2$ of Tall fescue(TF), and $10g/m^2$ of Kentucky bluegrass + $10g/m^2$ of perennial ryegrass mixture(KB+PR) onto 2m${\times}$2m(width${\times}$length) zoysiagrass plots with 3 replications.1 to 9-sca1e of visual quality and visual color were measured after treatment, Consequently cool-season turfgrass overseeding gave a good performances of extending the green periods and enhancing the turf grass quality. KB1 and KB2 were found to be excellent performances for visual quality and visual color compared to PR, TF, KB+PR and control. KB2 showed better turf performances than KB1 within Kentucky bluegrass overseedings. Turfgrass color was kept up for 10 months by overseeding of cool-season turfgrasses(KB1, KB2, PR, TP, KB+PR) compared to about 5~6 months by zoysiagrass(Control). The visual quality and visual color of PR and TF showed good performances during a green-up period of spring, but decreasing tendencies through the summer.Percent diseases data revealed also higher ratings for PR and TF compared to for KB1 and KB2.

본 실험은 한국잔디 신품종 '장성초록'(품종보호출원:2013-3)과 '장성샛별(품종보호출원:2013-4)의 개발에 관한 것이다. 2010-2011년에 국내 잔디 주 생산 단지인 전라남도 장성 지역에서 수집한 101개 유전자원의 특성 평가를 통해 2개 계통을 선발하였다. 선발계통 중에서 CY6097(장성초록)과 CY6069(장성샛별)은 봄철 휴면타파 속도가 빠르고, 초기 생육속도가 우수하였다. '장성초록'은 엽색이 연녹색이며, 엽 너비가 4.4 mm로 중엽형이다. 지면에서부터 첫 번째 잎까지의 높이가 3.2 cm로 낮아 낮게 깎기가 가능하며, 초장 평균도 18 cm로 낮게 자라는 특성을 갖고 있다. 늦가을 휴면진입 속도가 늦어 녹색 보유 정도가 많으며, 봄철에도 타 잔디에 비해 휴면타파 속도가 빠르다. '장성샛별'은 엽색이 진녹색이며, 엽 너비가 3.5 mm로 중세엽 형이다. 지면에서부터 첫 번째 잎까지의 높이가 4.3 cm로 높고, 초장 평균도 22.6 cm로 높다. 봄철 휴면타파 속도가 빨라 조기 수확이 가능하기 때문에 장성잔디 재배 농가에서 고품질 뗏장 생산에 유용하게 활용될 수 있을 것으로 판단된다.

This study selected Yangpyung as a target site because Yangpyung is a area of high value blessed with well preserved natural resources and beautiful natural scene and where thoughtless development and malformed use of land are in progress under the mask of hotel, accommodations and sales facility which fits the interests of land owner. As for the method used for this study, I inquired into domestic/international instances and the concept of existing environmental indicators and assessment of suitability with a view to establish assessment indicators and pose the concept through theoretical investigation of green-network and to establish green-network. 17 articles of environmental indicators such as aspect analysis, contour, greenbelt, DEM, NDVI, nature conservation area, reservoir and area for the promotion of agriculture were chosen as a actual analysing n data for setting up assessment indicators. From the result of analysis, as anticipated, green zone in Yongmusan areas within Youngmun and Seojong areas were the center of green-network in the wide area green-network in Yangpyung and the restricted area by basin system, road and legal regulation was selected as spot area and finally arable land and reservoir were selected as base which connects core with spot.

본 연구에서는 녹차 완제품에 원적외선을 처리한 후 물 추출물을 제조하여 항산화능 및 catechin류의 변화를 조사하였다. 녹차 물 추출물의 flavanol 함량은 무처리구(145 mg/g)에 비하여 원적외선을 10분간 처리한 경우 160 mg/g로 증가하였으나, 20분간 처리하였을 경우에는 90 mg/g으로 감소하였다. 또한, DPPH 라디칼 소거능의 경우 원적외선을 10분간 처리한 녹차 추출물의 경우 62.57%로서 무처리구의 61.58%에 비해 약간의 증가를 나타내었지만, 원적외선을 20분간 처리한 경우에는 59.98%로서 감소하였다. 한편, 녹차 추출물의 epicatechin류(EGC, EGCG, EC, ECG)의 함량은 원적 외선의 처리 시간이 증가할수록 감소하였으며, catechin류(GC, C, GCG, CG) 함량은 원적외선을 10분간 처리하였을 때 가장 높게 관찰되었다.

The adoption of Green Frame is expected to provide economic benefits, since construction costs are reduced by the in-situ production of precast concrete column and beam. The cost reduction can ultimately be realized by saving transportation costs and the overhead and profit of PC plants. The cost structure of Green Frame, which is built up using composite precast concrete members, is similar to that of a bearing-wall structure, but the difference in construction process has resulted in some cost differences for a few items. In particular, production and installation is the principal work involved in Green Frame made by precast concrete members, while form and concrete work is the principal work for a bearing-wall structure. As such, the rental time and fee for a tower crane should be compared through time analysis. To verify reliability, this study focused on developed residential projects to estimate the construction costs. Through this analysis, it was found that the costs of Green Frame were 1.57% lower than the costs of bearing-wall structure. The results of this study will help in the development of a management plan for the structural work of Green Frame.

Our society confronts a new social demand to protect the environmental equity of the people, and the green open space that is a representative public property which takes a very important role for the residents in less privileged urbane area in terms of providing amenity without requiring individual expenses additionally. This study aims to identify the current status and problems based on the environmental experiences of the actual residents, excluding the simple physical status, in relation with supplying public property of green open space, and the study put focus on the old downtown area of Jeonju-si which is a test-bed of urbane regeneration planned by the government. Residents in less privileged area evaluate the importance of green environment of park very highly as a factor to enhance their quality of life, but as they do not have well-established environmental infrastructure to back up their needs practically, they face difficulties to use such environment and show low level of satisfaction. In particular, as such characteristics appear remarkably among the least privileged urbane people in the less privileged urbane area, their dependence and expectation upon the environment of green open space is very apparent and, therefore, it is urgently needed to improve their environment for public green park area for the less privileged urbane people.

Because of lack of accurate understanding of the mechanism of urban heat island (UHI) phenomenon and lack of scientific discussion, it is hard to come up with effective measures to mitigate UHI phenomenon. This study systematically described the UHI and suggested the solutions using green-infrastructure (green-infra). The factors that control UHI are very diverse: radiant heat flux, latent heat flux, storage heat flux, and artificial heat flux, and the air temperature is formed by the combination effect of radiation, conduction and convection. Green-infra strategies can improve thermal environment by reducing radiant heat flux (the albedo effect, the shade effect), increasing latent heat flux (the evapotranspiration effect), and creating a wind path (cooling air flow). As a result of measurement, green-infra could reduce radiant heat flux as $270W/m^2$ due to shadow effect and produce $170W/m^2$ latent heat flux due to evaporation. Finally, green-infra can be applied differently on the macro(urban) scale and micro scale, therefore, we should plan and design green-infra after the target objects of structures are set.

The green roof industry have been developed with Europe, North America, Japan. At the same time, being recognized the important of green roofs in domestic industry and we just start to develop the relative technology as analyzing the future direction of advanced technology. Recently, local self-government including Seoul support the system for green roof which provide 50% of working expenses form of Matching Fund by Seed Money. As years go by, the number of build up the green roof has gradually increased to be proved. At this result caused by management of system in government, unstructured construction system, low development of support technology. In this study as analyzing the present of technical development, supporting by law and system for the advanced waterproofing and root penetration resistance technology, we suggest the development direction of it to be compared with application advanced technology and we could strengthen the international competitiveness to be industrialized the green roof considering system, technology, human infrastructure.
