Scrub typhus is an acute febrile disease caused by the pathogenic bacterium Orientia tsutsugamushi, belonging to the Rickettsiaceae family. The shotgun proteomic analysis was performed using the sera of scrub typhus patients to identify the proteins having their origin in O. tsutsugamushi. Three different databases approaches were used for the identification of the proteomes. We identified the RsmD, an RNA methyltransferase as the commonly detected protein from all three approaches. This protein was not detected in the sera of healthy negative controls. We believe that this protein is a potential biomarker of Orientia tsutsugamushi present in the sera of scrub typhus patients.

국내 농업은 농업인구의 감소 및 고령화, 농업경영비 상승 등으로 농업여건 개선이 시급한 실정이며, 이는 밭작업뿐만 아니라 수도작 등 모든 농작업에서 대표적인 문제로 대두되고 있다. 농작업 중 밭작업은 노동집약적이며 강도가 모든 작업 중에 최고의 노동 강도이고, 전정, 퇴비 살포, 제초, 시비, 유인, 수확 등 여러 가지 작업이 많고 기계화하기 어려운 작업이 대부분이다. 특히, 밭작물의 수확작업은 기계화율이 최저이므로, 여러 가지 작업 단계 중 수확작업에 소모되는 노동력 비율은 매우 높은 것이 사실이다. 이에 따라 많은 종류의 수확기들이 개발되어 있지만. 자주식 일체형 단일작물 제품이 주를 이루어 농민들의 구입비용 사용과 작물에 따라 기계를 따로 구입해야 하는 문제점이 있다. 현재 농작물 수확기를 파는 업체는 농업기계 가격집 기준 약 200여 개 업체에서 판매되고 있는데, 모든 업체가 자주식 일체형 단일작물 제품이거나 현장에서 개조한 제품이 주류를 이루고 있다. 본 연구에서는 곡물 및 채소 수확작업이 가능한 다목적 수확 작업기의 구현을 위해 프레임을 설계하고 프레임의 구조해석에 대한 연구를 진행했다.

The output power and RF spectrum in the PCS relay station are necessarily controlled for providing high quality service. The effect to other channel will be minimized by develope the measuring and controlling techniques in the base station for the 21 channel which is assigned to the PCS. In this paper, we developed the remote monitoring RF spectrum analyzer which is possible to control of output power level from main base station to local base station through the relay station's RF spectrum analysis and remote monitoring.

Problems related to chronic alcohol use common in neuropsychiatric fields, but the concerns about alcoholic neuropathy is much lower to clinicians than other alcohol related problems. We experienced a 54 year-old male alcohol dependent patient who complained of the weakness in both lower legs. He suddenly could not stand or walk showing the flaccid tetraparesis and areflexia on hospital day 7. We should differentiate alcoholic neuropathy from Guillain-Barre syndrome clinically. He showed abnormal electromyographic finding with predominantly no sensory potential and no sensory nerve conduction velocity in lower legs. We successfully treated alcoholic neuropathic pain with amitryptiline without any side effect. According to this case, Psychiatrists should pay more attention to alcoholic neuropathy in alcohol related patients via detailed physical examination, and treat them more aggressively without any fear.
