The confinments in the maternity facilities are increasing to year by year. It is significant to consider the utilization of maternity facilities, for the planning them in the area. I found that the basin is a model arer type in Tohoku region, and I inuestigated the utilization of maternity facilities in the basin where is shown in Figure-1. Generaly, the maternity beds needed for the area according to the formula: [numerical formula] where A: represents the annual number of Admission L: represents the average length of stay. I found that (a) A are decided to some standard values by the arer types. (i.e., mainly whether the area have maternity facilities or not.) (b) L are different of the types of maternity facility. Innestigted maternity facilities' L are from 12 days to 15 days. (c) The number of patients present on a given day varies according to Poisson's low. Thus, needed maternity beds in the area could be calculated by applying these factors (a), (b) and (c), and then by deciding (α)^* and anerage rate of occupancy according to circumstans. [numerical formula] where α: constant for every sort of equipment, E(n): expected number of persons who overflow above n. m: average or expected number of persons who come and use the equipments at a random instate of observation.
