임신성 간내 담즙정체증은 비교적 예후가 좋은 담즙정체성 질환으로 대개 임신 후반기(third tri-mester)에 발병하며, 출산후에 후유증없이 회복되지만 다음 임신에서 재발될 수 있다. 주된 임상증상은 황달과 소양감이며, 스칸디나비아와 칠레에서는 전체 임신중 1∼6%로 다른 나라들에 비해 높은 빈도를 보고되고 있다. 한국에서는 아직까지 증례보고나 빈도에 관한 보고가 없는 실정이다. 저자들은 임신 31주째 부터 생긴 황달과 소양감이 있었던 26세 여자 환자가 35주째 생긴 진통으로 본원에서 응급 제왕절개술로 조기분만후 현저한 담즙정체의 호전이 있어 임상적으로 임신성 간내담즙정체증으로 진단된 1례를 경험하였기에 보고하는 바이다. Intrahepatic Cholestasis of Pregnancy(IHCP) is a relatively benign cholestatic disorder that generally commences late in pregnancy, disappears abruptly after delivery, and frequently recurs with subsequent pregnancy. The main clinical manifestations are pruritus and jaundice. There was no case report of this disorder in Korea. We diagnosed IHCP in 26-year old female who had experienced jaundice and pruritus since 31th gestation period. She took emergency cesarian section because of premature labor and breech presentation. The jaundice and pruritus disappeared after delivery.

<P>There are debates about whether rainwater is suitable as drinking water. A serious shortcoming of the debate is that there are differences in the design and management of rainwater harvesting (RWH) systems. This study is based on the performance of two RWH systems that are used for drinking purposes at a kindergarten and a primary school in Cu Khe, Vietnam. Each system comprised a painted galvanized iron roof, a first-flush diverter, two stainless steel tanks connected in series, a calmed inlet, mosquito screens on open holes, PVC pipelines, filter cartridges, and a UV sterilizer. During 18 months, stored rainwater was sampled five times, and treated rainwater was sampled four times. Twenty-three water quality parameters were analyzed, including pH, total dissolved solids, turbidity, nitrate, nitrite, ammonia, hardness, arsenic, iron, cadmium, nickel, chromium, manganese, mercury, selenium, lead, zinc, <I>Escherichia coli</I>, and total coliform. It was found that all the physicochemical qualities of the stored rainwater, prior to treatment, satisfied the World Health Organization (WHO) drinking water guidelines. After physical filtration and UV sterilization, all parameters, including microbiological indicators, satisfied the WHO drinking water guidelines. Further management strategies to stabilize water quality were discussed.</P>

The role of biofilms in improving microbial quality in rainwater tanks is herein evaluated. We investigated microbial behavior after inoculation of the bacterium, Pseudomonas aeruginosa, in pilot and full-scale rainwater tanks with different surface-to-volume (S/V) ratios. In the pilot-scale experiments, there was a decrease in the total number of inoculated cells sampled from the water and from the bottom and wall surfaces of the tanks. Cell death contributed to the observed cell decline due to low-nutrient conditions. After four days, 99% of the inoculated P. aeruginosa had been removed from the water phase in pilot tank 2 and after five days in pilot tank 1. The faster removal rate in pilot tank 2 was due to the higher S/V ratio. In addition, the faster removal rate of planktonic P. aeruginosa in the full-scale tanks with high S/V ratios suggests that there is an optimal S/V ratio that ensures the removal of bacteria from rainwater tanks. These microbial observations on pilot and full-scale rainwater tanks lead us to conclude that biofilms play a significant role in improving the quality of stored rainwater.

본 논문에서는 Ultra-Wide-Band(UWB) 영역 측정을 활용한 이동객체 위치추정과 이동객체 위치정확도를 개선하기 위한 방법을 논한다. 실외환경과는 달리 실내에서는 여러 가지 노이즈로 인해 이동객체의 위치추적이 어렵다. UWB는 최근 위치추적 응용에서 주목을 받고 있는 라디오 기술이다. UWB의 영역측정 기술은 cm 수준의 정확도를 제공한다. UWB의 데이터 전송과 정밀한 영역측정, 물질관통의 특성은 실내위치추적 응용에 적합하다. 본 논문은 UWB 영역 기술과 파티클 필터를 이용한 이동객체의 위치추정 알고리즘을 제안한다. 기존 위치추정 알고리즘들은 이동객체의 위치추정을 한 후에 예상되는 오차와 bias 값을 제거하였다. 그러나 이 논문에서 제안한 알고리즘은 먼저 예상되는 UWB 영역 거리 오차를 제거하고 난 후에 이동객체의 위치를 추정한다. 본 논문에서는 제안 알고리즘이 기존 이동객체의 위치 추정 후 오차를 제거하는 방식보다 위치정밀도가 좋아졌음을 실험을 통하여 보였다. 본 연구에서는 UWB를 이용하여 고정되어 있고 위치를 알고 있는 세 앵커들과 이동객체 간의 추정 거리로부터 bias값과 반복 영역 오차 값을 제거한 후 삼각측량을 하여 이동객체의 위치를 추정하였다. 마지막으로 파티클 필터를 사용하여 이동객체의 위치 정밀도 개선을 한다. 실험 결과는 제안 위치추정 방식이 실내 환경에서 더 정밀함을 보인다. This paper addresses the problem of moving object localization using Ultra-Wide-Band(UWB) range measurement and the method of location accuracy improvement of the indoor moving object. Unlike outdoor environment, it is difficult to track moving object position due to various noises in indoor. UWB is a radio technology that has attention for localization applications recently. UWB`s ranging technique offer the cm accuracy. Its capabilities for data transmission, range accurate estimation and material penetration are suitable technology for indoor positioning application. This paper propose a positioning algorithm of an moving object using UWB ranging technique and particle filter. Existing positioning algorithms eliminate estimation errors and bias after location estimation of mobile object. But in this paper, the proposed algorithm is that eliminate predictable UWB range distance error first and then estimate the moving object`s position. This paper shows that the proposed positioning algorithm is more accurate than existing location algorithms through experiments. In this study, the position of moving object is estimated after the triangulation and eliminating the bias and the ranging error from estimation range between three fixed known anchors and a mobile object using UWB. Finally, a particle filter is used to improve on accuracy of mobile object positioning. The results of experiment show that the proposed localization scheme is more precise under the indoor.
