  • 벼의 주요 해충인 먹노린재에 대해 실내에서 충체분무법과 기주분무법을 통해 시판 중인 유기농업자재(EFOM) 27종을 대상으로 살충 활성을 평가하였다. 그 결과, 유기농업자재 7종(EFOM-8, -10, -12, -13, -19, -20, -26)에서 기주식물에만 살포하는 것보다 충체에 직접 살포되어 접촉하는 경우에만 높은 살충 효과를 보였다. 실내 벼 포트 검정에서는 선발된 7종 모두 담수 조건에서 살충률이 73.3% 이상이었으며, 특히 EFOM-13과 EFOM-20은 퇴수 조건에서보다 담수 조건에서 살충률이 1.5~1.8배 높은 차이를 보였다. 야외 간이 검정에서 EFOM-10 (마늘 80%), EFOM13 (님 62%), EFOM-26 (고삼 70%+에틸알콜 28%+제충국 2%)는 7일차 담수한 논에서 88.9%의 높은 방제가를 보였고 퇴수한 논보다 방제가는 1.4~1.9배 높았다. 선발된 EFOM-10을 살포한 농가의 담수한 논에서도 7일차 방제가는 86.2%로 퇴수한 논의 방제가 61.9%보다 1.4배 높았다. 종합적으로 살포액의 충분한 충체 접촉과 논의 담수 조건이 유기농업자재의 방제 효과를 높일 수 있음을 보여주었다. 이러한 연구 결과가 앞으로 농가에서 적용할 수 있는 최적의 먹노린재 방제전략 수립에 도움이 되기를 기대한다.

  • This paper is relate to the result of pilot test in Asan. In order to evaluate the characteristics of behavior and deformation in Asan and to analyse the effect of soft ground treatment, preloading, two types of paper drain and pack drain were constructed in the ground. Settlement gauges, pressure meters, pressure cells and ground water gauges were monitored and also borings and piezoncone tests were performed. As a result of analyse, every vertical drained area was consolidated over 90% degree of consolidation but preloaded area was not reached to 90%.

  • Anomalous systemic venous return to the right atrium is clinically innocuous and cause no functional disturbances or physiologic abnormalities by themselves and consequently require no treatment but may be surgical importance. We experienced a case of adult TOF combined with anomalous systemic venous drainage. Rudimentary right SVC with draining left sided vertical vein and IVC with separately drained left vein was revealed at operation time. With the bicaval cannulation, large sucker was used for drainage of blood from the left hepatic vein. Postoperative angiocardiogram showed above findings and combined double inferior vena cava at lumbar level.

  • 우리나라의 수경재배 면적은 2001년말 현재 736㏊로 순환식이 296㏊, 비순환식이 440㏊를 차지하고 있다. 수경재배에서의 양액관리방법은 작물 및 재배시스템의 종류에 따라 다르지만 작물이 흡수하고 남은 양액이 양액탱크와 재배조사이를 왕복순환되는 순환방식과 양액탱크에서 재배조로 공급된 후 배출폐기되는 비순환방식(흘러버림식)으로 나누어진다. (중략)

  • Overconsolidated clays have a different stress history according to the deposit environment. The stress history is classified into (i) rotation angle of stress path, (ii) overconsolidation ratio, and (iii) magnitude of length of recent stress path. Stress-strain behaviour of overconsolidated clays strongly depends on these stress history. In this study a series of drained stress path tests were carried out. Test results indicated that stress-strain behaviour of overconsolidated clay(focused on strain rate) depends on OCR and length of recent stress path, especially rotation angle.

  • We experienced one case of TAPVC patient who was 39 years old man with mild dyspnea on exertion and easy fatigability. He was the oldest patient among TAPVC which was reported in Korea. Preoperative echocardiogram, cardiac catheterization and angiogram revealed supracardiac type TAPVC drained through left innominate vein. An anastomosis between common pulmonary venous trunk and left atrium, pericardial patch closure of ASD and ligation of left vertical vein were performed with extracorporeal circulation. The postoperative course was uneventful and discharged with excellent general condition and has been well during 8 months follow-up.

  • A 17-year-old man was admitted for chronic anterior chest pain and dyspnea. He was undergone pericardiocentesis for chylopericardium and thoracostomy tube drainage for right sided chylothorax. Approximately 2000ml per day from right chest tube was drained during 20 days Supradiaphragmatic ligation of thoracic duct was performed and there was no drainage postoperatively and immediately antituberculous medication was done.
