      • 입제의 수면처리에 의한 주요수도해충의 동시방제

        최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

        본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

      • 원적외선 건조에 의한 곡물 가공 부산물의 항산화능의 변화

        이승철,배성운,김정한,정태준,조철우 경남대학교 환경문제연구소 2001 환경연구 Vol.24 No.-

        Effect of far-infrared drying to cereal processed byproducts was tested for antioxidative ability. Electron donating abilities of rice hull, rice bran, and barley bran after far-infrared drying were 93.88%, 91.50%, and 90.59%, respectively. According to TBARS, the inhibitions of lipid peroxidation of rice hull and rice bran were maintained independently on far-infrared drying and simple heating drying, while those of barley bran were decreased with the simple heating drying. The antioxidant ability of rice processed byproducts was more stable than that of barley byproducts. Isovitexin, the main antioxidant compound of rice byproducts, suggested to play an important role in the characteristics of rice byproducts.

        Dietary composition is a major determinant of cancer risk in human and experimental animals. Major and minor components of the diet may enhance or suppress the metabolism of carcinogens. In this study, the methanol layer, methanol and hexane partition layers of compositae species including Artemisia princepa var. orientalis, Arctiem lappa, Chysanthemum coronarium, Lactucascariola and Carthamis tinctorius were screened for the cytotoxicity on human hepatocellular(HepG2) and human cervix epitheloid carcinoma (HeLa) using MTT method. The methanol partition layer of Artemisia princeps var. orientalis(APMM) showed the strongest cytotoxic effects on HepG2 and HeLa cells among the other compositae species extracts. The cytotoxicity of APMM on HepG2 and HeLa cells were 94% and 95%, respectively a dose of 50㎍/ml of extracts.

        Wire-cut electric discharge machining is technique in the midst of development, and the factors of effect on working characteristic are various. Purpose of this study is to obtain efficient machining condition for metal mold of satisfactional quality from experimental study in wire-cut electric discharge machining with alloy tool steel STD11. In this study, the effect of peak discharge current[Ip], gap voltage[Vg], and spark cycle[T] on machining speed[F], kerf width[G], and surface roughness[Ra] in wire-cut electric discharge machining are discussed mainly. It is found that F is function of Ip, Vg, T and expressed ad F = {α*Ip*(V-Vg)+β}/T[mm/min]. Relationship between Ra and F can be written as Ra=γ*F+δ[μm]. G is proptioned to Ip and Vg but is not connected with T. If the average roughness of metal mold is, therefore, decided, the machining speed and efficient machining conditions can be calculated.

        The tool geometry parameters and cutting process have complex relationships. Until now, various cutting test were needed to acquire optimal design of end mill for the purpose of high speed machining, due to the insufficient knowledge about cutting process in high speed machining. Using various tools with different geometry, relationships between tool geometry parameter (rake angle, clearance angle, length of cutter) and cutting process (cutting force, surface accuracy, surface roughness) have been studied. Acquired data can be used to design optimal tool for high speed machining and developed tool geometry design S/W.

        韓鉉培,金成煥 서울市立大學校 1985 論文集 Vol.19 No.-

        In this paper, the change of EMC signal of Masseter muscle is demonstrated by AR model which obtained from LPC method. This method is more efficient than the analysis of characteristic frequency. In fatigue muscle compared to normal state, the power spectrum of EMG signal shifted about 30Hz to ward lower frequency. By comparing and analyzing the spectrums of normal person and a subject having records of TMJ syndrome, It is proposed that TmJ syndrome is neuropathic and the another clinical possibility which diagnosis TMJ syndrome with this analysis.
