This paper describes the background in which the working stress in the traditional print-motif cutting, so called Katatagami, and VDT works in a bank office. There existed postural problems that should be optimized according to reduce stresses.
The result of this study, problems concerning (1) sitting postures and their discomfort problems in work tasks occurred during the traditional Katagami cutting and the VDT work tasks, and (2) strategies of their reducing stresses extracted from the factors considering the necessity of the reducing discomfort postures in sitting and visual tasks, are referred. To solve above problems, by using analysis of working posture, gaze movements, EMG and eye mark camera measuring methods, toward optimize working stress are described in this paper.

Nursing care is one of the occupations which deteriorate low back pains. To analyze the cause of the pain, we performed a questionnaire survey. As the result, the pain occurred when tall nurses help patients sitting from standing position, and short nurses help them standing from sitting position. The opinions against introducing a helping machine in this field was only 3%.

Due to a mass of traffic accidents, the number of spinal cord injuries has been increasing. When the spinal cord is injured, the communication pathway between the brain and the extremities is blocked. As a result, the extremities are paralyzed. In their daily life, a function of reaching hand for an object is one of important functions as shown in eating. Although the hand can be moved by using functional electrical stimulation (FES) which is a method of controlling muscles by direct stimulation with electricity in case they are intact, or using robot arm, there is no excellent method for pointing a hand position currently.
In this paper a new pointing device to control a hand was proposed. And the execution was confirmed by applying the device to a FES system. The total system comprised a pointing light, a set of photo-transistors, an A/D converter, a personal computer, a D/A converter, a stimulator , and electrodes. A subject sat on a chair with his arm lying on an orthosis so that it can move horizontally. The pointing light was mounted on his cap, and illuminated to the place where he desired to move his hand. On his wrist the photo-sensor was mounted which could detect the position of the center of the intensity distribution. The computer was used to determine the muscle to be stimulated the command and the intensity, and transfer to the stimulator via the D/A converter.
Experiments with a 21-year old male subject were carried out to test elbow joint movement through the system. Results showed that the examinee successfully moved his hand to designated points. The speed of movement was 20~50°per second.
