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.

Background: Anastomotic leakages are one of the most serious complications after rectal cancer resection. The aim of this study was to identify the relevant risk factors of anastomotic leakage after low anterior resection for rectal cancer. Methods: We reviewed retrospectively the medical records of 251 patients, who underwent low anterior resection for rectal cancers between January, 2001 and December, 2004. All patients underwent a tumor-specific mesorectal excision. We excluded the patients underwent emergent surgery, protective stoma formation and used pelvic drainage. Results: The mean distance of the tumor from the anal verge was 8.0 cm (3-16 cm). Lower anterior resection was performed in 214 patients and ultra-low anterior resection in 37 patients. Fifteen patients had preoperativechemoradiation for rectal cancer. The anastomotic leakage was identified in 10 patients (4.0%). Seven patients with anastomotic leakage underwent corrective surgery.Other postoperative complications included 5 rectovaginal fistula (2.0%) and 4 intra-abdominal abscess (1.6%). The incidences of anastomotic leakage were significantly different according to preoperative chemoradiation (13.3% vs. 3.4%, p=0.05) and rectal obstruction (33.3% vs. 3.3%, p=0.00). Conclusions: In patients with history of preoperative chemoradiation and rectal obstruction, the careful management for anastomotic leakage is necessary

The electrochemical reduction of sumithion in various surfactants, LaLS, CTABr, Triton X-100 and in acetonitrile solution has been examined by DC, DP polarography and cyclic voltammetry (CV). Especially, in anionic surfactant, NaLS solution, the height of reduction wave is dramatic eliminated and half-wave potentials are shifted to strong negative potential (-2.7 volt vs. Ag-AgCl) by repulsion of nitro group in sumithion and anionic micell surfaces. The processes of reduction of sumithion were irreversibly electrochemical mechanism and the result of the reaction at high cathodic potential (-2.7 v. vs. Ag-AgCl), O,O-dimethyl-O-(3-methylhydoxyaminophenyl) phosphorothioate is formed as major product via O,O-dimethyl-O-(3-methylnitrosophenyl) phosphorothioate in NaLS micell solution.

The effect of strain aging on tensile behavior and properties of API X60, X70, and X80 pipeline steels was investigated inthis study. The API X60, X70, and X80 pipeline steels were fabricated by varying alloying elements and thermomechanicalprocessing conditions. Although all the steels exhibited complex microstructure consisting of polygonal ferrite (PF), acicularferrite, granular bainite (GB), bainitic ferrite (BF), and secondary phases, they had different fractions of microstructuresdepending on the alloying elements and thermomechanical processing conditions. The tensile test results revealed that yieldingbehavior steadily changed from continuous-type to discontinuous-type as aging temperature increases after 1% pre-strain. After pre-strain and thermal aging treatment in all the steels, the yield and tensile strengths, and yield ratio were increased,while the uniform elongation and work hardening exponent were decreased. In the case of the X80 steel, particularly, thedecrease in uniform elongation was relatively small due to many mobile dislocations in PF, and the increase in yield ratiowas the lowest because a large amount of harder microstructures such as GB, BF, and coarse secondary phases effectivelyenhanced work hardening.

Objectives : Nowadays many studies with MRI have reported structurai abnormalltles of corpus callosum of schizophrenic patients. However, the results are various and inconstant. In this study, we attempted to identify structural change of C O ~ U S cailosurn. Method : We measured the size of corpus callosum of the 24 schizophrenia patients (male 11, female 18) who were diagnosed by DSM-IV (19943, visited at department of psychiatry, catholic university hospital of Daegu from January 2002 to December 2003, by using midline sagittal slice of MRI. These results were compared with the size of corpus callosum of 25 controls (male 7, female 78). We divided corpus callosurn into 7 areas. We calculated and compared the areas of each subregion, mid-sagittal cerebral area, and entire corpus callosum. The results were analyzed by independent t-test. Result :When we compared subregion to corpus callosum adjusted wth mid-sagittal cerebral area, schlzoph-renia patients had significantly smaller genu (1.64k0.32 vs. 1.43k0.26 p<O.O5) and splenium (2.16f0.27 VS. 1.96+0.30 ; ~(0.05). Similarly, the ratio of total corpus callosum to midline sagittal cerebral area (%)(7.50*0.72 vs. 6.90t0.82 ~(0.05) was significantly smaller In schizophrenia than control group. Conclusion : In this study, we found significant differences in corpus callosum between schizophrenic patients and normal control group.

Since the residential load is an AC load, while the output of solar cell is a DC power, the photovoltaic system needs the DC/AC converter to utilize solar cell and must provide the sinusoidal wave current and voltage, at unity power factor in the case of driving to interact with utility line. PWM modulator must do stable modulation even though it contains the disturbance like a distortion and noise, and it needs compensation method, because there is a timing interval between sampling points and carrier waves, while the synchronous signal is controlled by the micro processor. In this paper, we maximaze output of solar cells which is propotional to variation of insolation, using single phase PWM voltage source inverter, and we can drive in high power factor with utility line by control and compensation method which is concerned with synchronous signal distortion and modulation delay, using low pass filter and phase shifter.
