We investigated the relationship of ventilation rates with the performance of advice nurses working in a call center. Ventilation rates were manipulated; temperatures, humidities, and CO 2 concentrations were monitored; and worker performance data, with 30-minute resolution, were collected. Multivariate linear regression was used to investigate the(More)

OBJECTIVES To investigate the safe distance from the tip of the cannulated screw to the apex of the femoral head, and to avoid cutting out of the cannulated screws from the femoral head. METHODS From November 2007 to April 2008, the placement configuration of the cannulated screws in the femoral head on the anteroposterior (AP) and lateral view was(More)
