한국인 태아에 있어서 좌고와 구간의 상관관계 및 구간계측치에서 좌고를 추산하는 공식작성에 관한 연구

Abstract

The authors have measured the 2, 100 Korean fetuses ranging from 16 to 36 weeks in age to induce the equation formulae for the estimation of sitting height in terms of the measurements of the trunk and the following conclusions have been drawn, L The correlation coefficients of over 0.9 between the sitting height and the measurements of the trunk are indicative of highly correlated condition. 2. Differences of approximately 4mm, in male and 3mm, in female are manifested between actual and estimated sitting heights, where the estimations are based on single measurement. 3. Differences of approximately 3mm. in male and 2mm. in female are manifested between actual and estimated sitting heights, where the estimations are based on double measurements. 4. The estimated sitting heights from double mea' surements are closer to actual one than from single measurement.
