컴퓨터기반실험(MBL)을 적용한 Wien의 변위법칙 실험장치의 제작
류성주,정기주,이기원 한국물리학회 2007 새물리 Vol.54 No.1
In this study, we fabricated af Wien's displacement law apparatus by applying microcomputer-based laboratory (MBL) tools for physics education in high schools. This apparatus is composed of a MBL, an electrically heated filament-type light bulb as a blackbody radiator, a prism for dispersion of light, a rotator for measuring the dispersive angle, and a photodiode for measuring the dispersive light intensity. We compare the wavelength values at a maximum specific intensity in the radiation spectrum obtained with experimental and theoretical methods (Wien's displacement law) under different temperatures. From the results, the relative error of experimental value was below 6 \%. 물리교육현장에서 활용할 수 있도록 MBL이 적용된 Wien의 변위법칙 실험장치를 제작하였다. 이 장치는 MBL, 흑체로서의 필라멘트형 백열전구, 빛을 분산하기 위한 프리즘, 분산각을 측정하기 위한 회전체, 분산된 빛의 강도를 측정하기 위한 광다이오드 등으로 구성되었다. 제작한 실험장치로 필라멘트의 온도에 따라 복사량이 최대가 되는 파장을 구하고, 그 결과를 Wien의 변위법칙을 적용하여 구한 이론값과 비교할 때 6 \% 이내의 상대오차를 갖는 것으로 나타났다.

A colonic pseudo-obstruction is a disorder that causes abdominal distension and abdominal pain similar to a mechanical obstruction, but there are no structural lesions that can obstruct the gastrointestinal tract. This condition can be acute or chronic. An acute colonic pseudo-obstruction, also called Ogilvie's syndrome, is believed to be a condition induced by other causes that are different from a chronic colonic pseudo-obstruction. The pathogenesis involves abnormalities in the autonomic nervous system induced by systemic diseases or medications, and it often improves when the primary causes are treated. On the other hand, a chronic colonic pseudo-obstruction can occur repeatedly without a particular cause. The authors encountered neuroleptic malignant syndrome that caused acute colonic pseudo-obstruction. This paper reports a case with a review of the relevant literature. This is the first case reported in Korea. This case shows that physicians should consider neuroleptic malignant syndrome as a cause of an acute colonic pseudo- obstruction.
