Purpose: The purpose of this study is to evaluate the effects of low-intensity direct current (LIDC) with electrode placement of negative poles at wound site on pressure ulcer healing. Subject: The subjects were elderly patients having a pressure ulcer (sacrum, 2 cases; thoracic supine, 2 cases; ilium, 1 case; greater trochanter, 1 case; lateral malleolus, 1 case), and healings of these ulcers had been retarded. The DESIGN-R of these ulcers were between 13 and 19. Methods: The negative electrode of silver chloride was inserted into the foam dressing on the wound surface, and the positive pole was attached on intact skin around the wound. Electrical stimulation (intensity: 80 µA; frequency: 2 Hz; pulse length: 250 msec; duration: 40 minutes) were administrated five times per week. On every treatment, opposite electrodes were shunted by electrical cable after the stimulation. Result: Size reductions were observed on all ulcers treated with LIDC and these ulcers were healed completely at 5 ~10 weeks after the beginning of LIDC stimulation. Conclusion: The pressure ulcer healings were promoted by negative LIDC stimulation. It is suggested that LIDC stimulation with consideration for electrical polarity could be effective for shortening of the pressure ulcer healing period.

In this paper, we propose a workload assignment policy for reducing power consumption by air conditioners in data centers. In the proposed policy, to reduce the air conditioner power consumption by raising the temperature set points of the air conditioners, the temperatures of all server back-planes are equalized by moving workload from the servers with the highest temperatures to the servers with the lowest temperatures. To evaluate the proposed policy, we use a computational fluid dynamics simulator for obtaining airflow and air temperature in data centers, and an air conditioner model based on experimental results from actual data center. Through evaluation, we show that the air conditioners' power consumption is reduced by 10.4% in a conventional data center. In addition, in a tandem data center proposed in our research group, the air conditioners' power consumption is reduced by 53%, and the total power consumption of the whole data center is exhibited to be reduced by 23% by reusing the exhaust heat from the servers.
