한국인과 백인및 흑인과의 혼혈아에 대한 체질인류학적 연구 제2편 생체계측학적 연구

Abstract

Upon physical measurement of 128 Korean-whites (male 71, female 57) and 73 Korean-negroes(male 45, female 28), the following conclusions have been drawn. 1) As for the longitudinal diameters, such as, stature, trunk length and sitting height, each hybrid group shows the value intermediate between those of the two races. The Korean-negro shows greater value than that of the Korean-white. 2) As for the transverse diameters of the body, such as, biacromial, chest breadth. chest depth and chest girth. each hybrid group shows the value intermediate between those of the two races. The Korean-negro shows greater values than that of the Korean-white. On pelvic breadths no significant value differences are revealed between the Korean-white and Korean subjects, but the Korean-negro shows smaller value than the Korean. In chest types according to the chest-girth index both hybrid groups show "wide type" in the age group of 1 to 2, "normal type" in that of 3 to 6 and "slender type" in that of 7 to 9 years which accords approximately to that of the Korean. 3) There is no notable difference between the Korean- white and the Korean in regard to the length of the upper extremities, while the Korean-negro shows greater value than that of the Korean. Both of the hybrid groups reveal greater values on the length of the lower extremities than that of the Korean. The Koreannegro reveals greater value than that of the Koreanwhite in this respect. The arm-leg index of the Koreanwhite points to the intermediate value between the two races, but it is more likely to be closer to the Korean side. 4) In head types based on the cephalic index, the Korean-white reveals brachycephalic or hyperbrachycephalic type, and the Korean-negro brachycephalic type, too. That is, both hybrid groups are closer to the brachycephalic Korean side. This proves the point made - 3 3 by Dunn lind Tao that the brachycephalic type is dominant to the dolichocephalic one. 5) Regarding the face types according to the facial index, both hybrid groups reveal leptoprosopic type, showing significant difference in contrast to the euryprosopic Korean. 6) In nose types based on the nasal index the Koreanwhite belongs to the leptorrhine, and the Korean-negro shows mesorrhine when one year old and thereafter turns to leptorrhine type, though the nose breadth is obiviously wide in contrast to the Korean-white. 7) In ear index both hybrid groups show shorter type than that of the Korean. 8) In the lips the Korean-white shows similar mouth breadth to that of the Korean and the Korean-negro shows greater one than that of the Korean. In the thickness of the lips the Korean-negro hybrid shows conspicuously greater value than that of the Korean.
