I have made a series of photographing experiments on the working posture with various heights of sink bottoms by using the chronocyclegraph method, in order to make clear the most suitable height for these items. I have evaluated the working posture from the viewpoint of a standard for the most suitable posture. At the same time, I have compared the above results with the ones described in the former report (Part 4), which are results of the RMR and the evaluation given by the subjects who were asked to give their opinion as to the most suitable height for working.
The results are as follows :
1. It was observed that the lower the height of sink bottoms, the more the subjects' bodies become bent over and move from side to side irregularly. Such effects on the parts of the body such as the vertex, the acromion, the olecranon and the ulna stylion, have also been observed. The ilio cristale and trochanterion do not move so much.
2. The height of the sink rim produces certain effects on the working posture, especially when the sink bottoms are too low or too high.
3. From the three experiments described above, the desirable height of sink bottoms is presumed to be in the range of about 65-70 cm (it is estimated to be about 40-45 percentage of the subjects' height), which is applied to different height of the sink rim.
