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.

A method for identifying the element properties of a truss structure is developed. In the study, the measured natural frequencies and modal shapes of the truss are used. The equation error including unknown parameter is constructed from the dynamic model. To analyze the inverse problem, the least square method is used. The inverse problem model is then formulated as a linear simultaneous equation and unknown parameters are estimated without complex iteration processes. Since it is difficult to obtain all modal data of a structure, the estimation of unknown parameters using limited modal data is studied. In selection of modal data, high modal data which is sensitive to the variation of parameters are selected. Through the suggested method, accurate parameters and damage of a truss structure are identified and detected.

윤상민 圓光大學校 法學硏究所 2004 法學硏究 Vol.20 No.-

It is impossible to explain the purpose of the punishment by one of these three theories - the retribution, the general prevention, and the special prevention. It is proper to understand the purpose of the punishment through the general research of the purposes, not through just one of them. Thus, this paper examines the plurality of the punishment purpose on the procedure - the legislation, the trial, and the execution of a sentence - of the criminal punishment, shows the purposes mainly pursued in each procedure, and finally presents the right punishment system.

成章鉉,孟允在,金文一 연세대학 산업기술연구소 1977 논문집 Vol.7 No.1

0.15% V was added to the modified Hadfield steel containing 3.2% Ni and after solution treatment, the steel was isothermally heated in the range 300℃ to 980℃. The precipitation of carbide and pearlitic constituent were tudied by means of microscopys and hardness test. The results obtained were as follows. (1) Carbide is more rapidly precipitated in the range of 600-800℃ and formed in the range of 350-910℃ with increasing heating time. (2) The precipitation of P.C. is more rapid at 700℃ and occurs in the range of 500-700℃ with increasing heating time. (3) The higher the heating temperature is the shorter the length of the acicular carbides becomes. (4) lncreased hardness is mainly caused by acicular carbide. The shape and the distribution of precipitates also bring about the hardness change.

A thirty two year-old male was referred with a chief complaint of mouth opening limitation, and maxillofacial pain including left TMJ area. The patient had been treated in a private clinic with medications and conservative treatments, without any improvements in symptoms. MRI findings showed a limitations in condylar head movements, and signs of disc adhesion without the Positional change. Panoramic views showed elongation of stylohyoid process. Brain C-T was taken due to the patient's complaint of headache, facial pain, and paresthesia of tongue, and the result showed no abnormalities. The first surgery included meniscoplasty and the removal of disc adhesion of left TMJ under the preliminary diagnosis of internal derangement with adhesion, and the patient displayed marked improvements in opening movements despite of persistent hemiparesthesia of left facial areas and tongue, and mild dysphasia. Therefore, the second surgery was carried out with the preliminary diagnosis of Eagle's Syndrome, and a resolution of neurologic symptoms was obtained. The final diagnosis of this case was Eagle's Syndrome with internal derangement, and the difficulties in diagnosis and treatment might be due to the existence of two separate diseases with similar symptoms.

In this paper, we propose the improved watershed algorithm that resolves the oversegmentation problem shown in the previous watershed algorithm and its modifications when the spatial video segmentation is performed. The principal idea of the proposed algorithm is merging the shallow catchment basin whose depth is less than a given threshold into the deeper one during flooding step. In the flooding process, the growth of the existing catchment basins and the extraction of newly flooded ones are accomplished. We present the experimental results using several MPEG test sequences in the last part of the paper. As a consequence, the proposed algorithm shows good segmentation results according to the thresholds applied by adding very small amount of calculations.

When time series data have the non-probabilistic uncertainty and the nonlinear characteristics, time series forecasting using traditional techniques is very difficult. Especially, traditional methods, which use past data directly in prediction procedure, cannot properly handle non-stationary data whose long-term mean is floating. To cope with this problem, a fuzzy forecasting method combined with the data preprocessing and model selection procedure is suggested in this paper. The proposed method is divided into the two phase. One is modeling phase, and the other is prediction phase. First of all in modeling phase, based on correlation analysis, we determine which sequences of differences of original time series data is more suitable for forecasting. Then, for each sequence of differences chosen from data preprocessing, fuzzy predictor with TS rule base is constructed. Finally an optimal predictor which yields the minimal MSE is selected. In prediction phase, we perform forecasting by a fuzzy predictor selected in modeling phase. Computer simulations show that the proposed method have better performance than traditional method for nonlinear time serves data.

This study has the research objective of finding the major socio-economic characteristics of environmentally conscious green consumers and then establishing pertinent marketing strategies designed to meet their needs. For this purpose, it investigates the relationship between the green consumers' attitude and their related purchase behavior. As already confirmed by existing literature which verified the gap between green perception and behavior, this study looked into correlations and causations among the perception, intention, and behavior of the green consumers. As a result, the green purchase behavior had relatively high correlation with the green orientation. But it didn't show significant relationship with behavioral intention variable. Also, in terms of the causality between attitude and behavior, the perception toward green consumer was found in high relationship with interest in green issues and willingness to pay extra money for the green products. However, it was found that the purchase experience of the environmental trademarked products was affected by the consumers' interest in environmental issues. Finally, the purchase experience of recycled products was in significant relationship with the credibility toward environmental messages and interest in environmental issues.

Simulated Moving Bed를 이용한 Bupivacaine 키랄분리 : (1) Preparative Chromatography를 이용한 기본조건 결정 (1) Optical Separation Conditions for Preparative Chromatography

윤지연,이중기,서성섭,최민호,박태진 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.6

Racemate Bupivacaine의 키랄분리를 위한 크로마토그래피의 최적분리조건을 조사하였다. Kromasii^(�) 키랄고정상에서 최적이동상조성 성분은 n-hexane/2-propanol/acetic acid/triethylamine, 99/1/0.3/0.05(vol.%)이였다. 이동상 조성성분인 2-propanol의 부피비가 증가할수록 체류시간과 분리도가 동시에 감소되었다. 이동상 성분 중에서 미량으로 존재하는 triethylamine이 증가할수록 피크의 sharpness가 증가하고 체류시간 역시 감소하였다. 또한, acetic acid가 없으면, 크로마토그래피 광학분할이 불가능하였으며 부피 0.3%에서 분리도가 가장 높음을 확인할 수 있었다. 한편, 키랄의약품의 대량분리방법중의 하나인 SMB(simulated moving bed)크로마토그래피 시스템(직경 1.0cm×10cm×8개 칼럼으로 구성)의 최적분리조건을 전산모사에 의해 구하였으며, 이를 실험으로 확인하였다. 그 결과 switching time 15분, feed의 유량 0.1 ml/min, desorbent 0.86 ml/min, raffinate 0.3 ml/min, extract 0.66 ml/min, recycle 1.0 ml/min일 때 100% 순도의 R-form과 S-form을 얻을 수 있었으며, 실험치와 전산모사치간의 오차는 ??2%이내였다. The chiral separation of racemate Bupivacaine was carried out to find the optimum condition for chromatographic system. The optimum species and composition for mobile phase were n-hexane/2-propanol/acetic acid/triethylamine, 99/1/0.3/0.05(vol.%) in case Kromasil� chiral stationary phase was employed. The retention time and resolution decreased with the increase in the ratio of 2-propanol in the mobile phase. The sharpness of peak and retention time decreased, as the content of triethylamine increased. Without the existence of acetic acid, the chromatographic separation didn't occur, and the resolution was the highest at the acetic acid volume ratio of 0.3%. The optimum condition of SMB (simulated moving bed) was determined by simulation and its results was compared with exprimental data from lab-scale SMB (10 mm 1D×8 ea). Rased on the SMB simulation and experimental results, 100% purity of R and S Bupivacaine were obtained and the error between the calculated and experimental value was within ±2%.
