We have processed the developing of vane damper with accurate control by using bevel gear which is a flow-control equipment of marine boiler's FD fan on this research. For the developing of vane damper, we have corrected some problem from welding & assembly process by changing the design, and for the case of an emergency case, we have applied the easy disassembly & assembly on that vane damper. Compared to rink type vane damper in current, we have focused on high efficiency with low price of that new developing damper. For selection of actuator, we have tried to find the propriety with our developing focus. Also, we have developed a jig of assembly processing for high productivity with quality, it caused the best assembly performance with heat-treated & processed parts.
Superficial Temporal Fascia Free Flap의 임상적 이용

Vascularized tissue coverage is necessary for the treatment of soft tissue defect on hand and foot dorsum, which cannot be successfully covered with simple skin graft due to exposed bone and tendon. Recently developed superficial temporal fascia free flap is an ideal tissue source for free transfer to distant sites where thin coverage is either desirable or mandatory. The superficial temporal fascia free flap combined with split thickness skin graft provides excellent bony coverage and tendon gliding with good aesthetic results on donor and recipient sites. The authors have found this flap useful (1) in covering exposed bone and tendon without adding unwanted bulk, (2) in providing thin flap coverage or lining in hand and foot area, and (3) in avoiding donor deformity. Recently, the authors have employed this free fascia flap in 3 cases which involved deep open wounds on hand and foot dorsum due to skin cancer, electrical burn, and extravasation of chemotherapeutic agent.
