Total body fat measurements were performed in 342 housewives. In 44 of them(age 38.4 yr.) both the densitometry and skinfold thickness methods were made and regression equations between skinfold and total body fat were derived. In the 298 housewives(age 35.0 yr.) skinfold thickness at four sites (arm, back, waist, abdomen) were measured and total body fat was calculated. The following results were obtained. 1. The data in 44 subjects by means of densitometry and skinfold thickness were: body weight: 51.8 kg, body length: 153.4 cm, body surface area: $1.47\;m^2$, body volume: 50.2 l, body density: 1.0334 kg/l, total body fat: 25.2% body weight, mean skinfold thickness at four sites 14.9 mm. 2. There were correlations of high degree between skinfold thickness and fat (%), fat (kg), and body density. The correlation coefficients were r=0.767, r=0.846, r= -0.765, respectively. Subsequently, the following regression equations were obtained. %fat=$0.39{\times}Mean$ skinfold thickness(mm)+19.36 Fat(kg)=$0.414{\times}Mean$ skinfold thickness(mm)+7.01 Body density=$-0.00099{\times}Mean$ skinfold thickness(mm)+1.0489 3. In 298 subjects mean skinfold thickness of four sites was 20.6mm and total body fat was calculated as 27.4% body weight from the above equation.

한국산 홍어과(科) 어류(魚類)에 대한 분류학적(分類學的) 고찰(考察)과 국명(國名) 및 분포(分布) 범위(範圍)를 정리(整理)하기 위해 국내외의 표본(標本)과 문헌(文獻)을 통하여 재검토(再檢討)하였다. 그 결과 홍어과 어류는 4속(屬) 11종(種), 즉 Bathyraja bergi 바닥가오리, B. isotrachys 저자가오리, Dipturus kwangtungensis 광동홍어, D. macrocauda 도랑가오리, D. tengu 살홍어, Okamejei acutispina 무늬홍어, O. boesemani 깨알홍어, O. kenojei 홍어, O. meerdervoortii 오동가오리, Raja koreana 고려홍어 및 R. pulchra "참홍어" (국명개정(國名改稱)) 등으로 확인되었다. Dipturus속(屬)과 Okamejei속(屬)은 아속(亞屬)에서 속(屬)으로 승격되었기 때문에 각각 "살홍어속(屬)"과 "홍어속(屬)"으로 국명개정(國名新稱)하였고, Raja속(屬)은 "참홍어속(屬)"으로 국명개정(國名新稱)하였다. 분류학적 재검토의 결과 Bathyraja bergi 바닥가오리도 분포함을 알 수 있었다. 한국산 홍어과 어류의 종(種) 목록(目錄)과 분포도(分布圖)를 제시하였다.
