동해안 오구굿의 무ㆍ불 습합 양상 - 김석출 오구굿을 중심으로
김창일(Kim Chang-IL) 동남어문학회 2006 동남어문논집 Vol.21 No.-
On October, 2005, opened ‘O-Gu Gut(오구굿)’ that deliver "Kim suk-chul" that was ‘the great shaman(큰무당)’ of East coast. At present, the Shamanism of East coast can be generally divided into Kang-won area, Kyong-buk area and Kyong-nam area, on this day they gathered all together. Until early 1990s, ‘Shin suk-nam(신석남)’ in Kang-won area, ‘Song dong-sook(송동숙)’ in Kyong-buk area and ‘Kim suk-chul(김석출)’ in Kyong-nam area are prominent shaman played with activity. However, ‘Shin suk-nam(신석남)’, ‘Kim suk-chul(김석출)’ died, ‘Song dong-sook(송동숙)’ died continuously April, 2006.<BR> Because “Kim suk-chul(김석출) O-Gu Gut(오구굿)” is exorcism that send to heaven the great shaman on East coast, Shamans of East coast participate, there is meaning that was taken to big scale as ‘O-Gu Gut(오구굿)’ rarely and last ‘O-Gu exorcism(오구굿)’ that ‘Song dong sook’ participates.<BR> Shamanism is maded slowly accepting the element of Buddhism for a long time. Therefore, the degree of fusion is serious to be hard to divide the element of Shamanism or the Buddhism. Specially, it is informed well that the tendency of Buddhism is strong in the Shamanism of East coast. But, It is not easy to present accurate answer that is clear about question if tendency is strong the element of Buddhism in terms of the Shamanism of East coast is some. Therefore, this thesis is meaning that it is informed well, but proved it positively.<BR> The contents of Shaman song and form of each ‘the tune of Gut(굿거리)’ was strong the element of Buddhism generally in whole exorcism. But, ‘the tune of exorcism(굿거리)’ of opening part and latter half was keeping the element of shamanism. I saw as centripetal force which keep framework of exorcism.<BR> Many ornaments of ‘the exorcism place(굿당)’ is borrowing the element of Buddhism. Of course, there is new meaning attaches as is used, most were receiving almost as it is without transformation<BR> As a result, ‘the tune of exorcism(굿거리)’ and Shaman song keep each the tendency of shamanism while receive the element of Buddhism greatly. But, I could make sure that ornaments of ‘the exorcism place(굿당)’ is appearing tendency which use as it is original state of Buddhism strongly.
전기 임피던스 단층촬영법에서 적응 문턱치 기반의 관심영역 기법을 사용한 영상 복원의 개선

전기 임피던스 단층촬영법은 주입 전류와 측정 전압을 기반으로 관심 도메인 내부의 도전율/저항률 분포를 복원하는 비파괴 영상 복원 기법이다. 본 논문에서는 역문제 계산시간을 줄이고 더불어 공간 해상도도 향상시키기 위해, 적응 문턱치 기반의 ROI(region of interest) 방법을 제안하였다. INTERMODES 방법에 의해 적응 문턱치가 계산이 되고 이 값을 기반으로 전체 도메인으로부터 ROI가 결정된다. 그리고 영상 복원의 계산 도메인을 ROI 내로 국한시켜 반복적 가우스-뉴턴 방법을 적용하여 저항률 분포를 추정하였다. 제안한 방법의 성능을 평가하기 위해 수치실험을 수행하고 그 결과를 비교분석하였다. Electrical impedance tomography is a nondestructive imaging modality in which the internal resistivity distribution is reconstructed based on the injected currents and measured voltages inside a domain of interest. In this paper, an adaptive threshold value based region of interest (ROI) method is proposed to improve the spatial resolution of reconstructed images as well as to reduce the computational time of the inverse problem. Adaptive threshold value is calculated by INTERMODES method and ROI is determined from the domain based on this value. Moreover, the computational domain of image reconstruction is restricted within a ROI and iterative Gauss-Newton method is employed to estimate the resistivity distribution. To evaluate the performance of the proposed method, numerical experiments have been performed and the results are analyzed.

전기 임피던스 단층촬영법은 전극을 통해 주입된 전류와 측정된 전압을 기반으로, 내부 도전율 분포를 복원하는 기술로, 비교적 새로운 비파괴 영상 복원 기법이다. 본 논문에서는 이원 혼합물 유동 응용분야에서 온라인으로 적용시킬 수 있도록, 역문제의 계산시간을 줄일 뿐만 아니라 공간 해상도도 함께 향상시킬 수 있는 역문제 해법인 빠른 반복적 가우스-뉴턴 방법을 제안하였다. 제안한 방법의 영상 복원성능을 평가하기 위해 모의실험을 수행하고 그 결과를 비교분석하였다. Electrical impedance tomography is a relatively new nondestructive imaging modality in which the internal conductivity distribution is reconstructed based on the injected currents and measured voltages through electrodes placed on the surface of a domain. In this paper, a fast iterative Gauss-Newton method is proposed to increase the spatial resolution as well as reduce the inverse computational time in the inverse problem, which could be applied to online binary mixture flow applications. To evaluate the reconstruction performance of the proposed method, numerical experiments have been carried out and the results are analyzed.
