화학적방제와 생물적방제를 상호보완적으로 사용하여 해충을 방제하기 위해 천적에 대한 저독성 약제와 천적의 안전방사시기를 설정하였다. 고추와 착색단고추에 등록되어 있는 52종(살충제 33종, 살균제 19종)의 살충 살균제를 충체침지처리법과 잎침지처리법으로 독성을 평가하였다. 살충제의 충체침지처리 후 애꽃노린재 성충에 대한 저독성약제는 milbemectin유제 등 14종이었으며, 잎침지처리법에 의한 저독성약제는 12종이었다. 처리한 살균제 19종은 모두 천적에 대해 저독성을 보였다. 약제살포 후 1일에 안전방사 가능한 약제는 pyraclofos, methomyl, thiodicarb, esfenvalerate bifenthrin, alpha-cyrermethrin, etofenprox, fenvalerate, imidacloprid, acetamiprid, abamectin, emamectin benzoate, spinosad, indoxacarb등 14종이었으며, 네오니코티노이드계 농약은 잔류독성이 길게 나타났다. For the development of integrated pest management system by harmonizing biological and chemical control, some experiments were carried out to select low toxic pesticides and to evaluate residual toxicity to natural enemies. Leaf dipping method and body dipping method were set up for evaluating toxicity to minute pirate bug, Orius strigicollis adult. We had tested 52 kinds of pesticides (33 insecticides, 19 fungicides) commonly used to control greenhouse insects, mites, and disease pests to natural enemies at the recommended concentration. Fourteen insecticides by body dipping method, 12 insecticides by leaf dipping method and 19 fungicides were selected as low toxic pesticides to O. strigicollis adult. After insecticide spraying at recommending dose on the sweet pepper plant, we examined residual effect of insecticides by introducing natural enemies on different days. Safety interval for introduction of O. strigicollis adult was established according to residual toxicity of pesticides. Safety insecticides at one day after treatment were pyraclofos, methomyl, thiodicarb, esfenvalerate bifenthrin, alpha-cypermethrin, etofenprox, fenvalerate, imidacloprid, acetamiprid, abamectin, emamectin benzoate, spinosad, indoxacarb. However, residual toxicity of nee-nicotinoids last up to 21 days to O. strigicollis adults.

고랭지배추 재배지에 발생하는 나방류 해충의 방제에 생물적방제와 화학적방제의 조화로운 이용을 위하여, 배추 재배 시 사용되는 약제 중 배추좀나방의 천적인 배추나비고치별 (Cotesia glomerata) 에 대해 저독성을 보이는 약제를 선발하고 잔류독성을 평가하였다. 배추나비고치벌에 대한 저독성 약제선발 방법으로 먹이처리법 (Diet treatment method), 잎침지처리법 (Leaf dipping method) 및 충제침지처리법(Body dipping method) 을 확립하였다. 배추에 등록되어 있는 주요 살충제 31 종을 추천농도로 희석한 후 배추나비고치별 성충을 충체침지처리한 결과 22종이 저독성 약제로 선발되었으며, 배추에 등록된 살균제 및 제초제 15 종은 배추나비고치별 성충에 모두 독성이 낮았다. 배추에 13 종의 살충제를 처리하여 일수별로 배추나비고치벌 성충에 대한 잔류독성을 평가한 결과, 약제처리 l일후에 방사해도 안전한 약제는 thiacloprid, acephate, chlorfenapyr, clothianidin의 4 종이었으며, 3 일후에 방사가 가능한 약제는 imidacloprid, deltamethrin, thiamethoxam, dimethylvinphos, emamectin benzoate이었다. For the development of integrated pest management system by harmonizing biological and chemical control, some experiments wee carried out to select low toxic pesticides against natural enemies. and their residual toxicity were evaluated. Leaf dipping method, body dipping method, and diet treatment method were set up for the toxicity evaluation against Cotesia glomerata adults. We had tested 46 different pesticides (31 insecticides, 11 fungicides, 4 herbicides) at recommending concentration commonly used to control diamond back moth, disease and up-land weeds in chinese cabbage field. Twenty three insecticides, eleven fungicides, and four herbicides were shown to be low toxic to C. glomerata adults in the treatment of body dipping. After insecticide spraying at recommending dose on the chinese cabbage, we examined residual effect of insecticides by introducing natural enemies on different days. Safety interval for the introduction of C. glomerata adults was established according to the residual toxicity of pesticides. Safe insecticides for the introduction of C. glomerata adults at one day after treatment (DAT) were thiacloprid, acephate, chlorfenapyr, clothianidin and at 3 DAT were imidacloprid, deltamethrin, thiamethoxam, dimethylvinphos, emamectin benzoate.

산화형 폴리에틸렌 왁스 제조에 있어서 주요 반응인자인 사용 왁스의 물성, 산화시간, 산화온도, 공기의 주입량 등에 따른 산가의 변화와 산화에 따른 폴리머의 물성를 분석하였다. 실험결과 주어진 반응조건 하에서 산화온도에 대한 산가의 변화는 160℃까지는 증가하였지만 170℃에서는 오히려 산가가 감소하는 경향을 보였고, 공기 주입량에 비례하여 산가는 증가하였다. 또한 사용한 왁스의 분자량이 낮을수록 산가가 높았다. 분자량과 밀도차가 공존하는 시료의 산화반응에서는 가지의 길이, 수 등에 의한 밀도보다는 분자량에 의한 영향이 큰것으로 생각되었다. 산화가 진행됨에 따라 분자량은 감소하고 분자량 분포는 넓어짐을 알 수 있었다. 온화한 조건 하에서 고산가를 얻기 위하여 자유라디칼 개시제를 촉매로 사용하였는데 같은 조건 하에서 무촉매인 경우에 비하여 고산가의 산화형 왁스를 얻을 수 있었다. 또한 DCPO(dicumylperoxide), HOPO(t-butyl peroxy 2-ethyl hexanoate), BPO(butylperoxide) 순으로 반감기가 긴 촉매가 효율적이었다. In oxidized polyethylene wax preparation, the effects of main parameters such as the property of used wax, oxidation time, oxidation temperature, air feed rates on the change of acid-numbers were investigated. The change in polymer property was also investigated. The results showed under given reaction conditions, the acid numbers with oxidation temperature increased upto 160℃, but at higher temperature, it decreased. The base resin which was lower molecular weight had higher acid number. The result showed molecular weight as a experimental parameter was more effective than density in oxidation experiment. In milder condition, free radical initiator was used for catalyst to get higher acid-numbers, which was successful in comparison to the non-catalyst system. Also the catalyst with longer half-life was efficient, in order of DCPO, HOPO and BPO.

This study introduces the Reliability-Based Design Optimization(RBDO) to enhance the kinematic and compliance (K & C) characteristics of automotive suspension system. In previous studies, the deterministic optimization has been performed to enhance the K & C characteristics. Unfortunately, uncertainties in the real world have not been considered in the deterministic optimization. In the design of suspension system, design variables with the uncertainties, such as the bushing stiffness, have a great influence on the variation of the suspension performances. There is a need to quantify these uncertainties and to apply the RBDO to obtain the design, satisfying the target reliability level. In this research, design variables including uncertainties are dealt as random variables and reliability of the suspension performances, which are related the K & C characteristics, are quantified and the RBDO is performed. The RBD-optimum is compared with the deterministic optimum to verify the enhancement in reliability. Thus, the reliability of the suspension performances is estimated and the RBD-optimum, satisfying the target reliability level, is determined.

This research proposes an automatic torsion beam axle optimization process and obtains the optimal torsion design parameters, such as thickness and shape. In order to construct an automatic analysis process, the multidisciplinary analysis models, such as modal analysis, roll mode dynamic analysis, and fatigue analysis, were equipped as batch mode. To understand a design space, the parametric study using torsion beam thickness and shape was executed. Considering the roll durability and K&C characteristics, a torsion beam axle could be optimized. For the automatic design process, the PIDO tool, called as P.I.A.n.O., are utilized. In conclusions, we could reduce a computer-aided simulation time and enhance the durability and K&C characteristics of torsion beam by optimizing thickness and shape.
