무선전력전달 시스템을 위한 코일을 설계함에 있어 코일 및 코어의 치수, 재료 및 형상은 효율과 직관된 요소이므로 가장 적절한 선택이 필요하다. 하지만 높은 효율을 가지는 무선전력전달 시스템을 설계하더라도 실제 이격거리는 가변하므로 예상했던 효율과 다른 결과가 야기된다. 본 연구에서는 기존의 E-E 형상과 C-C 형상 및 제안한 Plat C-C 형상을 페라이트 코어를 바탕으로 x-y-z 이격거리의 변화량에 따른, 결합계수를 유한요소해석 시뮬레이션을 통해 비교 및 분석하고 200W급 하드웨어를 통해 검증한다.

Before the Korean War, Korean mask dramas had been performed as parts of seasonal customs and had been passed down in connection with various seasonal events, such as village rites, tug of war, torch fighting, Jisinbabgi(stepping on evil spirits), Gilnori, and Sattonoreum. However, after the Korean War, the dramas were played independently regardless of those seasonal events; thus, they have lost their original functions and meanings. After the Korean War, the lion dance in the Bukcheong lion mask play included two lions (as opposed to one lion prior to the Korean War) and the Aeonesung and Sadang dances were added. The scene in which a lion eats a child changed to a lion eating a rabbit doll. Furthermore, whereas mask types used to be diverse, they are now standardized to one type of lion mask. In the Yangju Byulsandae-nori, eight monks and Waejangnye, Aesadang appeared in 'Aesadang Bubgonori', but now the Malddugi mask character is added. Current performances omit sexually suggestive scenes. In the pre-Korean War version of the old man and old woman act, the old man sang a song to the soul of the dead woman, but now a shaman appears and performs an exorcism. In the dialogues, vulgar and sexual statements have been shortened as many audience members are women and children. Regarding the appearance of the masks, the lotus leaf, the monk with Scabies, and sannim masks have been significantly changed. Bongsantalchum has also changed, especially in the old monk act. Previously, two Somu used to appear whereas now only one appears. The scene of the shoe seller's and the monkey's departure is also different. Furthermore, while the former masks once had big eye holes on each side of the nose, now the masks have smaller holes on the eyes.
