It is a field of nursing ergonomics to make patients comfortable and give nurse good working conditions. In hospital, patients actually have many problems on convenient and comfortable. According to previous study, those problems were classified into the following categories; hospital facilities, nursing equipment, working conditions for nurses. And then nurses individually have tried to readjust them to requirement. They showed us improvements need to be made, as one of realizing they require uch more individual variation. However, in hospital, they have condition of health of every kind and a variety state of activity, the condition is changeable accordingly they are getting better. We ran into against a question how we respond to them. In this time, I present that patient has many ergonomic problems even a activity of daily living. I would like to emphasize that it is important to think not only each problem but also relationship of those problems.

Purpose of this study is to develop guidelines on hospital environment of recovering from their illness. We observed the activities of inpatients using a video-tape recorder and we performed time study. In two cases, we could point out some promotive and obstructive factors that affected leaving their sick bed and activities of daily living development.

In this paper a basic study is given of the relationship between arousal level and blinks. The arousal level was defined as ‘Normal level’ when the subject was wide awake and the tasks were done correctly, and as ‘drowsy level’ when the subject was almost falling asleep and the tasks were not carried out. Blinks were detected by surface electromyogram (EMG) of orbicularis oculi muscles and also by a photo-sensor. The results show that (1) variance of intervals of blinks were larger in drowsy level, (2) duration of EMG was longer in drowsy level, (3) time delay of the closure of the eyelid after the onset of the EMG was longer in normal level, and (4) frequency components of the EMG changed to lower frequencies in drowsy level. From these results, detecting changes in blinking may be used effectively as information of the human mental state.

The design of a nursing robot or a human lifter will require force data in order to construct the machines. This paper deals with the development of force sensors for nursing movement. The sensors are applied by four-active-strain-gauge method. A nurse puts on the force sensors to her hands and/or feet like gloves and a pair of shoes. It can be measured the forces during nursing movement such as transference of a patient. The principle of strain gauge force sensors is showed, and is proven experimentally the action of the sensors by the use of the two models. Finally the experimental force sensors are described and demonstrated. The experimental force data were obtained through transferring patients from supine position to a sitting position on a bed.

The feelings of 105 cloths: 21 colour conditions and 5 weaving conditions, were evaluated by 45 undergraduate students. Causal relations between feelings were examined by using a structural equation model. The model was fitted for 22 subjects. It was suggested that the preference difference of cloths between subjects was caused by the causal relations between feelings.
