We are studying a novel concept of the on-line hospital system using a virtual environment called “Hyper Hospital”. The “Hyper Hospital” is a medical care system which is constructed in a distributed electronic information network using virtual reality (VR) as a human interface. In the present study, physiological and psychological responses of healthy young male subjects were measured by controlled experiments. Some physiological indices such as heart rate, blood pressure, and urinary catecholamine release showed statistically significant differences between results of control experiments using non-VR stimuli and results of VR loading experiments. However they were thought to be mainly from non VR origin. Subjective fatigue was complained by some sujects and they were thought to be indicating a direction of an improvement of our VR system in future. In conclusion, our VR system was proven to be safe when it is used for light medical purpose.

A word, intelligent, is attractive concept. It is possible to be the concept to develop materials science and engineemg. Thus, we define the intelligent degree (I_h24) of new materials from human-function points. Compared with the other intelligent degree (I_W and I_N), we discuss the values of I_W, I_N and I_h24 for materials.

An urea sensor was developed for the determination of urea in dialysate of hemodialysis. The urea sensor was constructed by combining an immobilized enzyme urease membrane with an ammonia electrode. The sensor responded to urea in concentration over 1-100mg/dl. The sensor is useful for the determination of urea clearance of dialyzer. The sensor can also provide a new laborsaving procedure for the estimation of blood urea concentration by measuring urea concentration in outlet dialysate during hemodialysis treatment.
