Defects of oral cavity occur in the course of treatment by surgery of cancer in the head and neck. More often they are the results of surgery after previous operation and irradiation already have been tried in an attempts to eradicate the primary cancer. The methods for repairing the oral cavity are variable and vary depending upon exisiting conditions and individual preference. Familiarity with the different techniques is necessary so that one suitable for the problem may be selected. Several methods of repair are known which utilize flaps designed from the forehead, the neck and deltopectoral area, but reconstruction with these flaps often fails because of the poor vascular supply due to previos surgery and irradiation in this area. So it is necessary to select the flap which not only have more abundant vascular supply but also serve to nourish the scarred bed, damaged by irradiation, that is implanted, Myocutaneous flaps have the advantage of transffering well vascularized tissue for reconstruction. Moreover, the free flap transfer has not yet proven to be thoughtly reliable, if it is indicated in selected cases, it may be a better reconstruction for the repair of the oral cavity. In this papers, we demonstrate the versality and different kinds of the methods which were used by describing experineces of 8 flaps, 7 myocutaneous flaps and 1 free flap.
Analysis of variation of tool retraction length in Zigzag Pocket Machining

This paper presents an analysis for the variation of tool retraction length. Tool retraction, in zigzag pocket machining, is a non-productive operation in which the tool moves to any remaining regions for machining. Earlier, we developed an algorithm of generating tool retraction length in simple polygonal shapes. In the algorithm, we considered a reflex profile of cutting direction in a polygonal shape. Considering reflex profiles of cutting direction, the polygon is decomposed to subregions, triangles and quadrilaterals, which do not need any tool retraction. Consequently, we propose a new result that the shortest length of tool retraction presents a cutting direction parallel to concave edges. Examples are shown to verify the validity.

N/A Background : The early diagnosis of candidemia is critical for the management. The candidemia is known to be associated with 10% of candiduria. But the risk factors in patients with candiduria who are associated with candidemia are not known. We analyzed the risk factors in patients with candiduria who are associated with candidemia. Methods : We retrospectively reviewed 164 patients with candiduria in Yonsei Medical Center from January 1998 to December 1998. Candiduria patients were divided into two groups. Candiduria patients without candidemia (Group 1 , 147 patients) and candiduria patients with candidemia (Group 2 , 17 patients). Results : 1) The mean age of the patients were 57.5 years in group 1 and 62.5 years in group 2. There were no significant differences in the sex ratio between the two groups. 2) Central venous catheter insertion (53%, 100% in group 1 , 2 ), hypotension (14%, 59% in group 1, 2), other associated infections (64%, 100% in group 1, 2), intensive care (41, 76% in group 1, 2) and fever (46%, 82% in group 1, 2) were the very significant risk factors in patients with candiduria who were associated with candidemia. 3) Urinary tract procedure (11%, 88% in group 1, 2), urinary catheter insertion (63%, 94% in group 1, 2), thrombocytopenia (17%, 41% in group 1, 2) and DM (8%, 24% in group 1, 2) were the significant risk factors of candidemia. 4) Candida colony count (cfu/mL) of urine culture was not a significant risk factor 5 ) Mortality rate (27%, 59% in group 1, 2) was significantly high in patients with candidemia. Conclusion : Central venous catheter insertion , hypotension , other associated infections , intensive care and fever were the very significant risk factors of candidemia in patients with candiduria.
