한국인 태아에 있어서 좌고와 하지의 상관관계 및 하지 계측치에서 좌고를 추산하는 공식작성에 관한 연구

Abstract

The authors have measured the 2.100 Korean 'fetuses ranging from 16to 36 weeks in age to induce 'the equation formulae for the estimation of sitting height in terms of the measurements of the lower .extrernity and the following conclusions have been drawn. 1. The correlation coefficients of over O. 9 between ',the sitting height and the measurements of the lower extremity are indicative of highly correlated condition. 2. Differences of approximately 2 mm. in male an I 16mrn, in female are manifested between actual and -estimated sitting heights, where the estimations are based on single measurement. 3. Differences of approximately 2 mrn. in male and 5 mm, in female are manifested between actual and ·estimated sitting heights. where the estimations are based on double measurements. 4. The estimated sitting heights from single and double measurements are closer to actual one in .sarn e degree.
