 note = {We have studied the effect of gravity on the intrauterine fetus development as the first step for investigating reproduction process of the human being in the space environment. In this experiment, we developed a method for measuring quantitatively the relation of movement of the mother to the posture of her fetus to estimate the effect of gravity on the fetus on the ground. As subjects we selected healthy pregnant five women and their fetuses in good condition, of 12-15 weeks along in their gestation period. We used a ultrasonic with which we can observe simultaneously movements of the fetus in three dimensions and a software for computing, with which we can analyze two dimensional movements, and established a method to demonstrate quantitatively a trend graph of change in posture of the fetus against the uterine wall axis of the mother. We found the possible motion of the fetus to keep the same location in the uterus as to be stable against the gravity. This method that we developed for study of reproduction in space should also endow the field of obstetrics medicine on the ground with benefit as well., 資料番号: AA0063706075},
