BONE-SALT QUANTITY EVALUATOR

摘要

PROBLEM TO BE SOLVED: To achieve a bone-salt quantity evaluation by giving a due consideration to a growth process of school children. SOLUTION: An actually measured value yi of the bone-salt quantity to be outputted from a bone-salt quantity arithmetic part 14 and an ideal value Yi to be outputted from an ideal value arithmetic part 20 are inputted into an evaluation part 16. The ideal value Yi is computed utilizing a multiple regression formula with the length, the weight and the period from the first menses taken into consideration. Thus, an ideal value close to an actual average value can be determined to allow accurate evaluation of the bone-salt quantity of a school children considering the degree of his growth.
