배진호 충북대학교 의과대학 충북대학교 의학연구소 1999 忠北醫大學術誌 Vol.9 No.2
연구목적: 부위 정맥 마취시에 소량의 근이완제를 국소 마취제에 혼합하여 환자에게 사용하였을 때 어떤 임상적인 이득이 있는지를 보기 위해 본 연구를 수행하였다. 대상 및 방법: 부위 정맥 마취로 손 부위의 수술을 받는 30명의 환자를 무작위로 추출하여 무작위로 15명씩 두 군으로 분류하였다. 베큐로니움 군은 0.5% 리도카인 40ml에 베큐로니움 2mg을 혼합하여 주입하였고, 대조군은 0.5% 리도카인 40ml를 투여하였다. 결과: 베큐로니움 군은 대조군에 비해 좋은 근 이완과 수술 조건을 제공했고(p<0.05), 통증의 경감도 있었다(p<0.01). 임상적으로 두 군간의 차단 발현의 기간에는 차이가 없었다. 결론: 부위 정맥 마취시에 베큐로니움을 혼합하는 것에 의해 부작용의 증가 없이 좋은 수술조건을 만들 수 있고 통증의 완화도 가능하다고 보여진다. Purpose: This study was undertaken to examine the possible clinical advantages of using muscle relaxant with intravenous regional anesthesia. Materials and Method: Thirty unpremedicated adult patients undergoing hand surgery were randomly selected to receive either 40ml 0.5% lidocaine or 40ml 0.5% lidocaine with 2mg of vecuronium. Results: The vecuronium group of patients had a significantly greater degree of muscle relaxation, easier reduction of fractures, and better operative conditions(P<0.05). Less pain was also reported during surgery(P<0.05). Clincally, there was no difference in the speed of onset of block between the two groups. conclusion: It is concluded that the addition of vecuronium to lidocaine improves the operationg condition during intravenous regional anesthesia with less pain during surgery.

N/A Effects of Si and Ni addition on the microstructure and mechanical properties of the Cu-12wt.%Al-5wt.%Fe-1wt.%Mn alloy have been investigated experimentally. Microstructure of the as-cast specimen is found to be refined markedly by additions of Ni and Si. By the addition of Ni, volume fraction of the k phase is increased, but volume fraction of the y phase is decreased. Hardness is increased with the addition of Ni, due to increasing of k phase which is harder than y phase. However, Charpy impact value is not significally decreased possibly due to the formation of isolate k phase. (Received February 19, 1998)

The purpose of this study was to examine the effect of the Vee Diagram, one of self-motivated learning instruments for elementary students, on their scientific attitudes, academic achievements, and scientific process skills. Results of the study were as follows: First, science lectures utilizing the Vee Diagram had significant effects on scientific attitudes. Especially, scientific attitudes including curiosities, voluntariness, activeness, and judging reservation, were meaningfully improved. Second, science lectures utilizing the Vee Diagram had significant effects on science academic achievements. Third, science lectures utilizing the Vee Diagram had significant effects on scientific process skills. In the area of basic process skills, observation and classification showed a significant results, while In the area of comprehensive process skills, data interpretation showed a significant results.
