This study was performed to evaluate the water purification properties of bio-composites planting blocks using oyster shell and effective microorganism that have high absorption ability of heavy metals and organics to develop environmentally friendly river embankment technique contained various factors such as oyster shells, effective microorganism, porous concrete and planting embankment block. To maximize greening effect, the seeds were arbitrarily sown. In addition, in order to analyze the effect of water quality purification after the planting, the samples were collected from each designated zone 1, 7 and 30 days after steeping in water. Then, the samples were analyzed in terms of seven test items such as SS, BOD, COD, T-N, T-P, pH, etc. on the basis of the test method for water pollution. The following conclusions were reached from the test result. As a result of analysis for water quality purification for the concrete block containing the effective microorganism, it was found that the values for SS, BOD, T-N and T-P for the sample taken after 30 days were lower than the initial values, which indicated that the water purification effect had been created. The result of the water quality purification analysis for the concrete block containing oyster shell showed that the values for SS, BOD, COD and T-P for the sample taken after 30 days were lower than the initial values which also indicated that it had been effective in water quality purification.

본 연구는 서울시에서 도로 방향과 가로수 식재형태가 여름철 도시 열환경에 미치는 영향을 분석하여 최적의 식재방식을 찾는 것을 목표로 하였다. 컴퓨터 시뮬레이션 프로그램 ENVI-met을 이용하여, 도로 4방향과 가로수 식재형태에 따라 68가지 시나리오를 수행하였다. 그 결과, 수목 식재 시 기온, 평균복사온도, 인간 열환경지수가 개선되는 것으로 나타났다. 평균복사온도의 감소는 도로와 접한 건물에 의한 태양 복사에너지 차단과 수목의 그늘효과에 기인하였으며, 도로방향은 풍속 감소에 영향을 주는 것으로 나타났다. 모든 시나리오에서 낮은 수고(6m), 넓은 수관폭(9m), 높은 엽면적 지수(3.0), 좁은 식재간격(8m)일 때 가장 큰 열환경 개선효과를 보였다. 도로 방향은 동-서 방향의 북측 보도에서 열환경이 가장 크게 개선되었다. 본 연구는 컴퓨터 시뮬레이션을 이용해 현실도시공간과의 차이를 감안해야 하고, 현장 실측과 더 많은 변수 고려를 통한 추가연구가 필요하다.

인도네시아 발리에서 한국 4개품종을 묘대일수와 재배법을 달러하여 공식한 결과 20일묘와 30일묘간에는 이앙후 출수기까지의 일수, 생육과 수양형질 및 수량에서 차이가 없었으며 시비량이 많고 재식밀도가 낮은 한국재배법이 수량 및 수량 구성요소가 유의성 있는 좋은 성적을 보였다.

본 연구는 고온 등숙으로 인해 미질 저하가 큰 벼 조기재배 실시에 적합한 재배법 개선을 위하여 품질향상을 위한 재식방법을 설정하기 위하여 수행하였다. 재식거리 $30{\times}14cm$ 이앙구에서는 포기당 재식본수가 3, 5, 7로 증가할수록 초장은 감소하고, 경수는 증가하였으나, 재식거리 $30{\times}18cm$ 이앙구에서는 재식본수가 증가함에 따라 초장 및 경수가 증가하였다. 재식거리 및 재식본수에 따라 간장 및 수장의 차이는 적었으나, 재식본수가 적을수록 수수는 적었고 입수가 증가하였으며, 재식거리가 증가함에 따라 수수 및 입수는 증가하는 경향이었다. 이앙구 간 쌀 수량에 따른 통계적 유의성은 없었다. 완전미 수량에서는 재식거리 $30{\times}18cm$ 이앙구에서 싸라기 및 분상질립 비율이 낮아 완전미의 비율이 높은 경향이었고, 3본 이앙시 403kg/10a로 완전미 수량이 가장 높았다. 재식거리 $30{\times}18cm$ 이앙구에서는 단백질 함량이 감소하고, 취반미윤기치 값이 증가하여 식미 개선의 효과가 있었다. 이러한 연구결과를 종합해보면, 벼 조기재배에서는 재식밀도가 낮은 넓은 재식거리($30{\times}18cm$)에 개체수가 적은 3본으로 이앙하는 방법이 조기재배에서 발생하는 문제점들을 개선시킬 수 있을 것으로 판단된다.

Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.

It is unavoidable to be formed slopes under special circumstance of Korea where 70% of the whole area are composed of mountains when civil engineering projects such as roads, site developments are increased with industrial development and horizontal expansions of urban area. Moreover, stability of the slopes become one of quite important issues under special meteorological characteristics that over two-thirds of annual average rainfall are concentrated in summer season and the localized torrential downpour are getting more frequent recently. Resulting in these circumstances, partial slope failures by debris flow of the high water content soils are occurred frequently in cutting soil slopes. In this case of debris flow slope failure, slope declination method are selected for their stable recovery because it is impossible to recover entirely by existing recovery methods. Seeding or special grass planting methods are followed separately without exception. The method by which entire recover with bigger stability ratio would be possible and grass planting work would be done simultaneously is developed. In this study, the results of the tests including a real construction history in a failed slope using developed method are described

본실험은 구약자의 수량증수를 위해 파종기별 저장 방법과 재배양식 절단방법과 자구의 크기, 차광효과를 구명코자 시험하였던바 결과를 요약하면 다음과 같다. 1. 파종기에 있어서 4월 20일 전파종양식에서보다 조기파종 4월 5일이 수량성이 증가하였다. 2. 저장방법시험에서는 일반저장 PC film에서 수량성이 가장 높았고 입모율은 우수하였으나, 반면 구약감자 출현율은 육아재배 PE멀칭과 PE터널에서 20일 촉진할수 있으나 특히 입모율은 주야간 기온차로 특별한 재배관리가 요망된다. 3. 자구절단방법 2절, 4절은 관행보다 자구수가 증가하였고 종자소요량과 대량번식이 유리하였다. 4. 구약감자 재배는 자연광(관행)보다 30%, 50% 차광처리에서 생육특성과 종자수량이 증가하였다.
