Small groups of 5th-year medical students performed a survey of hospital patient services in hygiene and public health, with an emphasis on patient waiting time. The purpose of this course was to give medical students the opportunity to experience the waiting time endured by patients and to obtain some understanding of the quality of hospital services from the patient's point of view. The survey was performed as follows. Groups of five students accompanied new patients in the department of internal medicine from registration until payment. The students recorded waiting time and examination time. During the waiting time, the students asked the patient questions to evaluate service. Patients were cooperative in giving responses during the survey. After the survey, the students summary proposed how to improve services for patients. By accompanying and talking with patients, the medical students were able to understand hospital systems from the patient's point of view. This course should prove useful for these students future careers in medicine.

The running behavior and muscle characteristics associated with voluntary running activity were studied in female Fischer 344 rats after 9 weeks of training in voluntary exercise wheel cages. The exercise wheel employed allowed a load to be added to the wheel axis. The running activity was recorded as the number of rotations every 10 s for 24 h, and the number of running bouts, running duration, running speed and distance run per day were varied. Addition of a load to the wheel axis allowed the running style to be changed, and reduced the running duration and speed in each bout. The voluntary running training was done with no load, 30% per body weight load, and 60% per body weight load, and as treadmill running (40 m/min, 60 min/day) .
In the voluntary training, a difference in the total running distance was observed with increased load. The total distance run under 0%, 30% and 60% load in the voluntary group was about 552, 475, and 438 km, respectively, after training for 9 weeks. As a result of training, the weights of dorsiflexor muscles tended to increase with treadmill running, whereas weights of plantar-flexor muscles increased significantly in the voluntary training groups. In the plantaris muscle, the cross-sectional area of all fiber types was not changed by treadmill training, but in voluntary training, almost every type of fiber was enlarged. Voluntary running with a 30% load increased the cross-sectional area of type I and type ha fibers in the plantaris muscle compared with no load exercise. However, no significant differences in the cross-sectional area of these fibers were observed between 30% and 60% load exercise. The fatigue tolerance of the plantaris muscle improved significantly in all training groups, and the 60% load group showed the highest value.
These results suggest that voluntary loaded running is more effective for muscle enlargement than treadmill training and/or voluntary training with no load.
