 note = {The aims of this study were to assess characteristics of the musculoskeletal stresses and to clarify the ergonomic problems of nursery school teachers during their tasks, especially those in charge or children less than one year old. In a questionnaire survey made on 102 subjects from 46 workplaces, complaint rates for musculoskeletal stresses were more than 30 % in many tasks such as bottle feeding, changing diapers, exercising and bathing babies, pushing baby carriages and feeding. Postures during the exercises of a baby were analyzed in 10 subjects at seven workplaces by using video tapes. The proportion of stressful postures was found to be different between subjects, which was partly dependent on the usage of a table and the position of their legs. Dimensions of some installations in seven nursery schools were measured, which were considered too low for workers. Optimum heights of the seats and armrests of chairs used for bottle feeding were estimated in 73 nursery school teachers and they were almost the same as those of chairs for ordinary clerical tasks. The optimum height of the platforms for changing diapers was also estimated at about 55 % of the subjects' heights. In conclusion, it was considered that there were many ergonomic factors which could be improved in the working tasks of nursery school teachers, though some effective improvements have already been implemented in their ways of working and the heights of certain installations.},
