The serum protein contents of normal Koreans(120) were determined by the low temperature methanol precipitation method. 1) The serum protein contents of normal Konean males(80) and females (40)are 7.4±0.5㎎% and 7.4±0.4 ㎎% respectively. 2) The serum A/G ratio of normal Korean males(80) and females(40) are 1.1±0.2 and 1.0±0.2 respectively. 3) There is no difference in the serum protein content between Koreans and other peoples. 4) No difference is observed in the serum A/G ratio between Koreans and foreign people, if the methanol precipitation method is employed. 5) The serum A/G ratio determined by paper electrophoresis and elution, is approximately same as that measured by the methanol precipitation method.

Pyruvic acid (PA) and αketoglutaric acid (αKGA) in blood were determined by paperchromatographic and electrophoretic methods after the preparation of their 2, 4dinitrophenylhydrazones. Both methods mentioned above were proved to be superior to Friedman’s method. PA and αKGA levels in blood of normal Koreans determined by paperchromatographic method are as follows; PA αKGA male (59) 83.6±13.5 Υ/10 ㎖. 18.2±4.0 Υ/10 ㎖. female (26) 77.2±10.9 Υ/10 ㎖. 17.3±3.9 Υ/10 ㎖. total (85) 81.0±14.3 Υ/10 ㎖. 17.9±4.1 Υ/10 ㎖. PA and αKGA levels in blood of normal Koreans determined by paper electrophoretic method are as follows; PA αKGA total (36) 84.7±17.8 Υ/10 ㎖. 16.6±4.3 Υ/10 ㎖.

본 논문은 100 nm GaAs pHEMT 공정을 이용한 W-band 광대역 저잡음 증폭기 설계에 관한 내용이다. 광대역 이득특성을 위해 극점 튜닝 기법을 이용하였다. 인덕터를 적절히 사용하면 트랜지스터의 캐패시턴스 성분을 매칭에 포함시켜 고주파의 손실을 막을 수 있는 장점이 있다. 저잡음 증폭기는 W대역에서의 충분한 이득을 얻기 위해 총 4단으로설계되었으며, 정전기에 의한 회로 손상을 방지하기 위해 입력단에 Shunt 인덕터를 이용하여 매칭하였다. 제안된 저잡음증폭기는 RF 및 DC 패드를 포함하여 1.78⨯0.743 mm2의 크기를 가지며, 80 GHz에서 16.2 dB 이득과 5.5 dB의 잡음지수를 달성하였다.

The serum βcarotene and vitamin A contents of normal Korean subjects were determined by the Bessey’s method which was modified to be able to use 2 ㎖. of sample instead of 0.06 ㎖. The results observed are as follows; (1) The serum βcarotene contents of male (286) and female (90) are 64.3±28.5 Υ/dl. and 74.2±27.5 Υ/dl respectively. (2) The serum vitamin A content of male (180) and female (85) are 30.6±13.6Υ/dl. and 28.9±11.9Υ/dl. respectively. (3) The serum βcarotene content of female is superior to that of male. (4) No great difference was observed between the results of author and those of other investigators.
