This paper describes the performance of centrifugal fan used for refuse collection system according to the number of splitters. To analyze the effect of blade numbers on fan performance, splitters installed between blades are introduced. The chord length of splitters is determined by 90 percent blade chord using the results of preliminary research. The fan performance is analyzed by three-dimensional Navier-Stokes analysis, and also compared to the results obtained by experiments. Throughout the experimental measurements and numerical simulation, fan performance can be increased by reducing the flow loss region mainly observed on the blade suction side. Pressure and efficiency are successfully increased by 3.6% and 4.4% compared to reference, respectively. Detailed flow pattern is also analyzed by the results of numerical simulation.

Background and Objectives : Interstitial cells of Cajal(ICC) are the pacemakers in gastrointestinal tract that modulates gastrointestinal motiliey and these cells also transmit neural input from enteric nerves to smooth muscles. Recent work on tissues from patients with motility disorders that suggest that loss or defect in ICC could be related to pathophysiology in human and animal models. Immunolabelling of ICC in intestinal wall is recently developed by using specific marker, anti-c-kit antibody. Immunohistochemistry was done for ICC network in attempt to provide a morphological basis for the mechanism regulating gastrointestinal motility Methods : Cryosection was done, and whole-mount preparations of mouse stomach, gastrointestinal tract were immunolabelled using the anti-c-Kit. Immunolabelled ICC networks were observed under a confocal laser scanning microscopy. Results : According to three dimensional reconstruction study, we found that the c-Kit-positive celluar networks were widely distributed in the gastrointestinal muscle (1) circular muscle layer(IC-IM), (2) myenteric plexus(IC-MY), (3) deep muscular plexus(IC-DMP) in ileum, (4) submucosal plexus(IC-SMP) and longitudinal muscle layer(IC-LM) in colon. Conclusion : The characteristic profiles of ICC celluar networks provide a morphological basis upon the mechanism regulating gastrointestinal motility. Additional studies for the enteric nerves-ICC interaction are need to evaluate the detailed roles of Icc in gastrointestinal tract.
