지방간에서 발생한 폐 지방색전증의 병리학적 및 임상적 의의에 대한 연구
권태정,강현욱 大韓法醫學會 2001 대한법의학회지 Vol.25 No.1
Fat embolism is the presence of fat globules in the peripheral circutation and in the lung, brain, kidney, pearl, and so on -not in the fine emulsion of a metabolic lipemia but in globules large enough to obstruct arterioles and capillaries. The fat droplets can deride from fractures of long bone due to disruption of the fatty marrow from extensive bruising of the soft tissue, and from fat tissue in burns. Fat embolism has also been reported in patients suffering from various diseases including alcoholism, fatty liver, diabetes mellitus and pancreatitis. We investigated 19 autopsies with fatty liver of varying degrees to establish a correlation between fatty change of limier and pulmonary fat embolism. Among 19 cases, 3 cases with moderate to severe fatty change of elver, and 1 case with submassive hepatic necrosis and mild fatty change showed Grade II pulmonary fat embolism. In histologic section with Sudan III stain, the arteries and capillaries of lung were occupied and distended by round, oval, or staghorn fat globules. The alveoli may contain edema fluid and blood Although the pulmonary fat embolism occuring in the presented cases didn't cause death on its own, one should be aware that a life-threatening mobilization of fat into the lungs and ever into the systemic circulation is possible In fatty fiver and submassive hepatic necrosis.

Lesions with coronary artery aneurysm (CAA) can become complicated during percutaneous coronary intervention. Here, we report a case of a 78-year-old man who developed a rupture, and spontaneous sealing of the CAA occurred after stent implantation, as shown by computed tomography coronary angiography.
WMS 시스템을 이용한 해양예측모델 데이터의 가시화 기법

최근 GIS(Geographic Information System)을 중심으로 다양한 정보를 지도위에 제공하고 있으며, 대표적으로 국외 의 경우 구글맵, 오픈스트리트맵, 빙맵 등이 있고, 국내의 경우 네이버지도, 다음지도, 브이월드맵 등이 GIS 기술의 한 부분인 WMS(Web Map Service)를 이용하여 서비스를 제공하고 있다. 본 논문에서는 현재 서비스되고 있는 벡터장 데이터 정보를 이용하여, 조류의 흐름도 와 스트림라인의 표출 방안 알고리즘 연구 및 사용자 편의성을 고려한 해양예측모델 데이터의 가시 화 방안에 대해 연구를 수행하였다. 기존의 조류 흐름도 표출 및 스트림라인 표출 알고리즘과 제안하는 방식의 성능을 비교 를 하여, 기존의 기술 보다 2배 이상 빠른 표출이 되는 것을 확인하였다. Recently, many companies offer various web-based map that is based on GIS(Geographic Information System) information. Google Map, Open street, Bing Map, Naver Map, Daum Map, Vwolrd Map, etc are the few examples of such system. In this paper, we propose a method to visualize ocean forecasting model data considering the flow diagram of tidal current, streamline expression algorithm, and user convenience by using vector field data information that is currently being served. It is confirmed that the proposed method of the flow diagram of tidal current, and stream line expression algorithm is faster than that of conventional ocean prediction model data by more than 2 times.
