 note = {Some statistic consideration were made on the age and residence of a total of 19,628 crew members of the whaling fleets, Kyokuyo Co., who had been engaged in Antarctic operations from 1956 to 1973. The mean age of the crew annually increased as: Mean age=0.7958T+20.7794 where, T=A.D.-1955. The patterns of age distribution for factory workers annually changed, as the pattern of poisson-distribution varied with the probability, p, for example, the pattern of 1963 well agreed to that of p=0.15, that of 1966 to p=0.3 and then that of 1970 may be approximated to be the normal distribution of p=0.5. The remaining rate of workers X years after their engagement was roughly estimated as 1/X. The most part of workers were from Tohoku region and the prefectures of their homes in the order of percentage were Miyagi, 31%, Aomori, 16%, Nagasaki, 13%, Kochi, 12% and Hokkaido, 10%. And also the residences of the crew were similar to that of factory workers., 長崎大学水産学部研究報告, v.42, pp.45-55; 1977},
