In order to effectively control the Ricania sp., we investigated the light response to adults and developed an adult capturing device using light with superior attractiveness. The preference among six light sources such as daylight color, green, etc. for the Ricania sp. adult was favored with daylight color 97 > black 79 = red 79 = blue 79 > green 24 > yellow 13. We have developed an adult catching device using the most preferred daylight colors and behavioral habits of the Ricania sp.. The capture device consisted of two daylight compact lamps (30W, 20W), a yellow plate, and a catcher using water, and caught about 700 individuals a day. The capturing device has a large amount of capturing because adult is activity at high nighttime temperatures, but the capturing amount decreased significantly when the temperature dropped below 23℃. More than 85% of the Ricania sp. adults were trapped for 3 hours from 19:00 to 23:00. Therefore, it is considered that the adult capturing device for the control of Ricania sp. is used from mid July to late August when the night temperature is over 23℃, and lights up from 19:00 to 23:00.

The developmental ecology and temperature-dependent growth model were calculated to develop the Scotinophara lurida control technology, which is mainly affected by environmentally friendly rice cultivation. The survival rate of S. lurida after overwintering in 2019 showed that 167 of 224 survived and the survival rate was 72.8%. Overwintering adult of S. lurida occur in rice fields in mid-June, spawn in early July, and first-generation adults develop in mid-August. In order to determine the temperature-dependent growth model, the growth periods by temperature and development stage were investigated in a incubator at 18, 21, 24, 27, 30℃ and 14L: 10D. The period from egg to adult at the temperature of 18, 21, 24, 27, 30℃ was 119.8, 73.1, 53.5, 39.4, and 82.0 days, respectively. The best development temperature was at 27℃. The regression curve was obtained by analyzing the relationship between temperature and growth rate using the Excell program, and the base temperature threshold and effective cumulative temperature for each development stage were calculated. From eggs to 5 nymphs of S. lurida the base temperature threshold was 17.9℃ and the effective cumulative temperature was 380.2 DD.

유역의 강우-유출 현상을 분포형으로 모의하기 위해서는 삼각형 혹은 사각형 요소로 유역을 모형화하고 각 요소에서의 수문성분의 변화를 해석하여야 한다. 본 연구는 사각형 요소인 격자로 모형화된 유역에서의 강우-유출 현상을 1차원 운동파 방정식을 이용하여 모의할 때 각 격자에서 발생된 흐름의 추적을 위한 격자 네트워크 해석에 대해 수행하였다. 격자의 흐름방향은 D8-method(deterministic eight-neighbors method)에 의해 결정된

유역의 수문현상을 해석하기 위해서는 다양한 지형자료와 수문 시계열자료가 필요하다. 최근 들어 DEM(Digital Elevation Model)과 수자원 주제도와 같은 지형자료 뿐만 아니라 수치예보자료 및 강우레이더의 관측자료와 같은 수문 시계열자료 또한 격자 형태로 제공되고 있으며, 이를 활용한 수문분석에 대한 다양한 연구가 이루어지고 있다. 본 연구에서는 이러한 격자형 자료를 이용하여 효과적으로 단기간의 강우-유출 현상을 모의하기 위한 물리적 기반의

본 연구에서는 하천유역에서 소수력 개발 대상지점에서의 최적규모를 결정하는 방안을 제시하였다. 제시된 방안은 지형 및 수문자료의 구축, 발전소 모의운영, 경제성분석, 최적규모 결정과 같은 일련의 절차로 이루어진다. 최적규모 결정을 위해 경제성 평가지표 가운데 하나인 순현가를 이용하였고, 이를 통해 최적 설계유량과 시설물의 최적규모를 도출하였다. 초기비용의 산출을 위하여 기존 소수력발전소의 비용 자료를 검토하여 함수식을 개발하였고, 편익 산정시 현재 공시된

소수력은 신재생에너지 중에서도 온실가스 배출량이 가장 적은 청정에너지중의 하나이며, 국내 부존량이 매우 풍부하기 때문에 최근 개발에 대한 필요성이 부각되고 있다. 그러나 국내에서 소수력 개발을 위한 자원조사나 연구는 1990년대 이후 매우 미흡한 상황이어서 체계적인 연구가 뒷받침 되어야 할 것이다. 본 연구의 목적은 소수력 개발의 계획단계에서 입지분석을 위한 방법론을 제시하는 것이다. 이를 위해서 제약기준과 입지기준을 설정하고 가중치를 부여하였으며, 각

lndoor landscape plays important roles in the environmental improvements of inner building and play leading roles in offering green space to urban communities. as proffessionally part of technically construction, constucting indoor landscape, we have to frame the standard of materials and the standard of materials and the construction expanses because the demand of indoor landscape have risen increasingly. Especially, indoor landscape have kept in being paltry and unproffesionalty under the present condition of no standards about the estimation of proper construction expenses, Also, when Unit Cost chart is made, there are no indicators or specific standards that evaluate unit price. So this study carried out to suggest the evaluating standards of plantings pen some areas. It can be the basis work of the making out the proper constructional expenes The progresses and details of this study were the followings -first, the list of indoor plants and the standard of planter were suggested, through case study of indoor landscape and blue-drawings. -second, the quantity of planting materials according to each standardized planter was suggested through the theoretical and numeric methods, the existed unit cost charts and survey of several indoor landscapes -third, the quantity of typical planting materials according to each standized planter was also suggested. The result of this study were the followings. -the quantities per unit area of indoor ground cover flowing plants were 176/ m' in case of 3 chi planter of the type of upper growing, 127 I m' in case of 3 chi planter of the type of side growing. They were 94/ m2, 51/ m2, 38/ m2, 28/ m2 in order 4 chi, 5 chi, 7 chi, 7 chi planter of type of upper growing. Also they were found out 67/m2, 32/ m2, 24/ m2, 18/ m2 in order 4, 5, 6, and ?chi planter of the type of side growing. This study have several limits suggesting only the quantity of plants per unit area, to make out unit cost. llereafter this study will be developed to suggest the unit standard and unit cost of the other materials besides planting materials in indoor landscape. And the labor cost per unit materials will be developed through the next studies on the basis of the result of this study.
