본 논문에서는 고리 1호기 해체 비용 추정을 위해 외국 원자력발전소 해체 비용 데이터를 현가화한 후 원자력발전소 해체 비용 추정 회귀 분석모델을 개발하였다. 이 모델 개발에 사용된 데이터는 해체 또는 진행 중인 BWR 13기, PWR 16기의 해체 비용 데이터이다. 회귀 분석모델 도출을 위해, 해체 비용을 종속변수로 정하고, 해체 원전의 운전 특성을 반영할 수 있게 고 안된 Contamination factor와 해체 기간을 독립변수로 선정하였다. 빅데이터 분석 도구인 R language의 통계패키지를 이용 하여 회귀 분석모델을 도출하였다. 이 회귀 분석 모델을 적용하여 고리 1호기 해체 비용을 예측한 결과, 미화 663.40~928.32 백만 달러, 한화 약 7,828.12억~1조 954.18억 원이 소요될 것으로 예측되었다.

ICT 기반의 해충 이미지 전송 시스템은 담배거세미나방과 파밤나방을 예찰하고 방제하는데 필요한 효과적인 유인 해충 전송수단이다. 시설 온실내 담배거세미나방과 파밤나방을 유인하기 위하여 스마트 트랩을 이용하였다. 스마트트랩은 나방류 해충유인을 위해 성페로몬 4종 장착하였으며 유인된 해충은 특수 카메라를 이용하여 이미지 촬영이 가능하였다. 또한, 해충유인 발광트랩 처리구는 황색광을 사용한 발광 트랩을 사용하였다. 또한 대조구로 기존에 널리 사용되는 델타트랩은 한 종류의 성페로몬을 장착하여 유인력 검정에 이용하였다. 성페로몬 한 종류만 사용한 델타트랩 처리는 담배거세미나방 페로몬 루어를 사용하였고, 4종류의 성페로몬을 설치한 스마트 트랩 처리구는 담배거세미나방, 뒷날개흰나방, 파밤나방, 왕담배나방용 성페로몬 루어를 사용하였다. 실험은 2018년 6월 1일부터 8월 31일까지 함안 시설원예연구소의 13m2의 소형비닐하우스에서 수행하였으며 공시작물은 파프리카 ‘시로코’ 품종과 토마토 ‘데프니스’ 품종을 사용하였다. 나방류 해충의 유인력 검정결과 파프리카와 토마토를 식재한 온실 모두 성페로몬 루어 한 종류를 설치한 델타트랩보다 유인발광 트랩 처리구에서 높은 나방류 유인율을 나타내었다. 시험기간 유인발광 트랩의 경우 유인 포획된 총 나방수는 파프리카 온실에서 평균 97마리, 토마토 온실에서 75마리가 유인 포획되어 가장 높았다. 그러나, 성페로몬 1종 및 4종을 설치한 델타트랩 및 스마트트랩처리구는 두 개의 온실 모두 평균 5마리 이하의 유인율을 나타내었다. 따라서, 시설내 나방류 예찰 및 유인 방제하기 위해서는 기존 성페로몬만 사용하기 보다는 유인발광 트랩을 함께 설치하는 것이 나방류 유인포획에 효과적이라고 판단되었다.

The tobacco cutworm, Spodoptera litura(Fabricius) is serious pest that hurts tomato crops, actives long time of the year. Without pesticide applications, sex pheromone delta traps through experiment first and second half setting during cultural seasons in glasshouse and greenhouse. We investigated captured number of S. litura both in and out side of the two type of tomato cultivated greenhouse. As a result of investigation, captured number of S. litura showed the wave and three high peak typed graph throughout 10 months experiment. First time expression of S. litura was late April in outside installed traps and after that occurrence rate increased gradually until late August. In september, the rate decreased remarkably to middle November in both in and out side treated traps. The result also expressed that captured average number of S. litura in inside of the greenhouse were 8~10 units, and were 15~20units in outside treated traps. Simultaneous installation of internal and external sex pheromone traps succeeded in eliminating a considerable number of S. litura male moths, and the number of larvae was expected to be considerably reduced. Consequently in the experiment, captured male number of S. litura were about 220 units in outside, on the other about 80 of S. litura captured in inside installed traps.

The attraction of the tomato whiteflies Trialeurodes vaporariorum, to four type of traps combined with a colored stickyboard and an light emitting lamp was investigated in 2016 in an tomato greenhouse. The colors of the sticky boardswere yellow and the peak wavelengths of the light emitting traps were 470nm(blue), 590nm(yellow) and 450~625nm(white).The type of traps was designed to directly illuminate the plants with an light emitting lamp and set along the lowerpart of the crops whose each sticky board was directed to the plants. This experiments showed that T. vaporariorumadults on average preferred (p>0.05) traps in blue lights(110±3.2adults/trap) compared to traps in yellow lights (71±1.4adults/trap)and white light traps(45±1.1adults/trap). The blue light trap(470nm) showed the most attractive to T. vaporariorum adults,followed by a similarly attraction to the yellow light trap(590nm), whereas the control (no light trap) was little attractiveto T. vaporariorum adults.

The tobacco cutworm, Spodoptera litura(Fabricius), is a major pest of tomato and frequently demands control measures. The timing of insecticide application is a key factor in determining its efficiency, so an experiment was designed to investigate this. Application of insecticide was based on three criteria: (i) the number of trap-caught moths in a Delta-type trap with a commercial sex pheromone lure placed in the center of the target area, soon after plant emergence; (ii) the percentage of plants exhibiting pinhole-type damage (10% or 20%) and (iii) the percentage of plants exhibiting shot hole-type damage (10% or 20%) compared to a check plot without any control measures. We found that the number of trap-caught moths was, compared to the other methods, the best means of deciding on insecticide application in tomato plant to control the tobacco cutworm. Using pheromone traps, we obtained the best performance of the insecticide Shinnago, causing > 90% larval mortality. Without insecticide application, tomato yield reduction due to the tobacco cutworm larva damage was 27%.

Recent enactments of the Nagoya Protocol and UPOV convention precipitated international competition to secure biological resources. To address these challenges in the case of mushroom industry, collecting and preserving the genetic resources are urgently needed. Mushroom Research Division, National Institute of Horticltural and Herbal Science, Rural Development Administration, has operated mushroom resource management facilities which consist of eight separate rooms with automatic temperature and humidity controllers for the safe preservation of mycelial cultures or voucher herbarium specimens. During the past three years the liquid-nitrogen (LN) cryogenic system for the permanent/semi-permanent preservation of the strains commercially or scientifically important are successfully installed, and the computerized resource management system using QR code are adopted. Up to now, 1,586 strains of 261 species in 79 genus of edible and medicinal mushrooms were preserved.

The PepMoV has been considered the most frequently detected potyvirus. When it co-infects with CMV or PMMoV, it gives severe impact to total pepper harvest in Korea. Since F1 hybrid that resistant to PepMoV has not been developed, we have developed transgenic peppers using Agrobacterium-mediated transformation with a Hc-Pro gene of the PepMoV. A large number of GM peppers were tested for resistance to the PepMoV, and after consequent self-crossing up to T4 generation, a highly tolerant pepper to PepMoV called T20 was selected. So far, BC4F1 lines have been selected by back-crossing with 4 elite lines through a breeding program. Very recently, based on molecular analysis, we have selected another event, #10-2, which is also resistant to PepMoV. Horticultural difference was investigated for both GM lines, #T20 and 10-2, and no significance was found comparing to non-GM lines.
