The electromagnetic radiation therapy is a typical treatment method for treating human body cancer. During the past 100 years, there has been a rapid change in the progress of medical technology, and there have been many developments in the last ten years. Computed tomography was introduced for radiation therapy, and Three-dimensional conformal radiation therapy was started through image reconstruction techniques. Through intensity-modulated radiation therapy which examines the radiation intensity from the same plane in another way, more complex and detailed treatment became possible. In addition, accurate treatment became possible via image-guided radiation therapy which increases the reproducibility of the patients position by using images acquired with the treatment equipment. Recently, with the advent of new equipment through the fusion of magnetic resonance imaging equipment and therapy equipment, it will give much help to radiation therapy. Such changes are expected to have many developments in the field of radiation therapy in the future.

Vector 合成法을 이용한 Booming Noise 低減에 關한 硏究
김재열,유신,오성민,장종훈,김갑중 조선대학교 생산기술연구소 1997 生産技術硏究 Vol.19 No.1
Booming Noise of a Automotive can be divided in Air Borne Noise and Structure Borne Noise. In this study, Booming Noise is reduced by the vector Synthesis method. The vibration that transferred by the engine is managed. The car that by the used model is composed of Mount system supported to three point with 2000 cc 14 engine FR vehicle. The vibration that is transmitted from propeller sharft and Differential Gear to Sub Frame and Suspention effect Booming Noise. but, The vibration that generated by the Mount has Booming Noise more than it. So, We research that sound generated by the Mount and reduce that Booming Noise used the Dynamic Damper. The Booming. Noise by the vector Synthesis. is reduced in 2000 ~ 4000 rpm front of vehicle. We know that Booming Noise is reduced into hoped for rpm by the vector Synthesis.
