Abstract
An analysis of the points of the controversy (1962) between K. Kogi and J. Hashimoto concerning industrial health technology is as follows :
1)The scientific work is distinct from physical work on social division of labour. 2) The actions to protect worker's health against unhealthy factors or to organize scientfically the labour are derived from the directive and/or administrative actions as workshop division of labour. 3) Above all, it is necessary for the professional activators on the problems of worker^ health, to be able to sympathize with the workers and their demands. 4) The physical and psychological studies link to the political economy by means of the labour process which is doubly defined as the general labour process and the labour process under the capital.
