한국과 미국 고등학교 생물 교과서 실험 활동의 탐구 수준과 탐구 기능 비교 분석
박철규,황진석,곽대오 韓國生物敎育學會 2009 생물교육 Vol.37 No.4
The purpose of this study was to compare inquiry levels and inquiry skills in laboratory activities between Korean and American high school biology textbooks by analyzing 136 laboratory activities in 5 Korean and 194 ones in 4 American textbooks. Laboratory activities in both Korean and American textbooks were mostly at structured inquiry level, and few ones were at guided inquiry level. But, the proportion of guided inquiry level in American textbooks was more than in Korean textbooks. Neither confirmation inquiry level nor open inquiry level was found in Korean or American textbooks. Inquiry skills of performance category were comprised thoroughly, and the proportion of each inquiry skill of the category was similar in Korean or American textbooks. Inquiry skills of planning and design, analysis and interpretation, or application category were not comprised thoroughly in Korean textbooks whereas all inquiry skills of the categories were presented in American textbooks. Moreover, the proportion of each inquiry skill presented in Korean textbooks was generally much less than in American textbooks.
직경이 다른 미세혈관 단단문합술의 방법에 대한 실험적 연구
박철규 大韓成形外科學會 1982 Archives of Plastic Surgery Vol.9 No.3
I have presented a experimental study of techniques for end-to-end anastomosis of small vessels of different diameters. To obtain a three times difference in diameter, the rat femoral artery was cut at two points-one near the inguinal ligament, the other at the knee joint. The cut arterial segment was removed, reversed, and replaced into the space between the severed carotid artery. I used three technique (30°oblique cut of smaller vessel and mechanical dilatation, fish mouth cut and mechanical dilation, one side fish mouth cut and mechanical dilatation) to solve the difficulties of anastomosis of vessel ends of different diameters. The success rates of patency are as following. 1. 30°obleque cut and mechanical dilatation: 29/30 2. fish mouth cut and mechanical dilatation: 30/30 3. One side fish mouth cut and mechanical dilation: 30/30
