This paper describes the first-year accomplishments in the R&D project entitled, “Electrodeless Fluorescent Lamp Technology Using High-Frequency Discharges (Linear and Circular Type),” supported by a contact from the Korea Energy Management Corporation (KEMCO). One of the most important accomplishments in the project is that the luminance of electrodeless fluorescent lamps is increased more than 25% when the hybrid technique of capacitive and inductive couplings is utilized for both linear and circular types of high-frequency discharge fluorescent lamps compared to the case where pure capacitive couplings are used. We present the results of the experiments and the status of the development efforts in the project.

The inferior rectus abdominis flap which can be used as a myocutaneous or muscle flap is one of the most frequently used flap. But its disadvantages are also well known. These are the possibilities of abdominal weakness or hemiation and in certain situations, its bulkiness especially in obese patients. To overcome these major drawbacks, very thin inferior rectus abdominis flap without muscle or with a very small segment of muscle of needed has been made by a thining procedure in which large volume of subcutaneous fatty tissue just beneath the subdermal vascular plexus was excised evenly with care to preserve circulation of the cutaneous flap. From March 1996 to April 1996, we resurfaced soft tissue defects of the dorsum of left foot, right knee and left upper arm in three patients using this thin inferior rectus abdominis free flap. The results were satisfactory in contour without bulkiness and there was no evidence of abdominal weakness or hemiation during follow up period more than 6 month, so we expect this flap can offer more wide indication of rectus abdominis flap in various site with no doubt of flap bulkiness and abdominal hernia and now we report this paper with review of literatures.
