Infective endocarditis is rare in end-stage renal disease (ESRD) patients, who have a poorer prognosis than the general population. Candida endocarditis is rare and has a poor prognosis among causes of infective endocarditis. A 45-year-old male was admitted with sepsis combined with a hematoma on his right back. Candida famata was cultured in his blood. We treated him with antifungal agents. Echocardiography was performed to identify vegetations and diagnose endocarditis. In this case, surgical therapy was impossible because the patient`s condition had deteriorated. We also administered antibiotics because methicillin-resistant Staphylococcus aureus was cultured from his sputum and a perianal abscess. The symptoms did not improve despite the ongoing treatment. Metabolic acidosis, hypotension, and a decreased state of consciousness developed and he died. We report a rare case of Candida endocarditis in an ESRD patient on hemodialysis.

In this study, we proposed the most efficient driving posture based on the analysis of quantitative muscular strength and fatigue degree according to posture. Since driving include complicated actions required by a variety of ability and cause by extremes concentration or strain, drivers tend to feel tired easily. However, drivers cant recognize the fatigue degree by themselves. Moreover, the method for measuring the quantitative fatigue degree exactly is quite difficult to be secured. 9 professional bus drivers were participated. We analyzed the quantitative legs muscular strength when operating each pedal. And then we also analyzed the muscular strength and muscular fatigue degree according to driving pattern during bus driving. Therefore, we suggested the most efficient driving posture.

Purpose: With the advancement of laparoscopic instruments and accumulation of surgical technique, laparoscopic liver resection is currently performed for various benign and malignant liver diseases. However, controversies still remain over laparoscopic liver resection for malignant liver diseases including HCC and its oncologic safety is yet to be established. This study aims at determining the safety, feasibility and short-term oncologic outcomes of laparoscopic liver resection performed for HCC. Methods: From July 2008 to March 2010, laparoscopic liver resection was performed at our hospital on a total of 45 patients with various benign and malignant liver diseases. Among these 45 patients, 16 patients diagnosed with HCC were reviewed retrospectively. Results: The mean age of the patients was 59.25, comprising 11 male patients (68.8%) and 5 female patients (31.2%). The location of tumor was left lateral in 7 cases, 4 cases in segment 6, 2 cases in segment 7, 2 cases in segment 5, 1 case in segment 4 and 1 case in caudate lobe. Wedge resection was performed in 11 cases, left hemi hepatectomy in 2 cases, left lateral sectionectomy in 2 cases, caudate lobectomy in 1 case. The mean operative time was 248.75 minutes. The mean hospital stay was 13.8 days, and there were no post-operative recurrences during the post-operative follow-up period. Conclusion: When performed by expert surgeons in selected patients, laparoscopic liver resection for HCC is a feasible and safe procedure.

Purpose: Chylous ascites is an accumulation of lymphatic fluid within the peritoneal cavity caused by obstruction or rupture of the peritoneal or retroperitoneal lymphatic drainage system. Postoperative chylous ascites is a rare complication of abdominal surgery. In the present study, we analyzed patients who developed postoperative chylous ascites after gastrectomy. Methods: From February 2003 to June 2006, we treated 7 cases of chylous ascites that occurred after gastrectomy for gastric cancer. We reviewed the medical charts of these patients retrospectively. Results: The incidence of chylous ascites after gastrectomy was 1.7%. Mean triglyceride concentration of the ascitic fluid was 437 ㎎/㎗ (range: 128 ㎎/㎗∼816 ㎎/㎗). Total parenteral nutrition and somatostatin were administered to 6 patients, and 1 patient was treated with oral diuretics and serial paracentesis. Conclusion: The incidence of chylous ascites is low, but may increase with more aggressive surgery. Surgeons should consider chylous ascites if the character of drainage is milky. Conservative management is usually effective for the treatment of postoperative chylous ascites. If conservative management fails, surgical management should be considered.

색채선별기는 양질의 곡물 유통을 위해 불량곡물, 이물질을 선별하는 시스템이다. 기존의 색채 선별기는 PC기반 제어시스템으로서 비교적 고가이고 부피가 크며 현장 환경에서 기계적 충격이나 먼지등에 취약하다는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 개선하기 위해 운영체제가 탑재된 임베디드 제어기 기반의 색채선별기를 제안한다. 색채선별기는 기본적으로 곡물의 유입량 및 속도를 조절해 주는 피터부, 곡물의 영상을 받아 이미지를 처리해 주는 카메라부, 카메라부에서 받은 정보를 이용해 양품과 불량품을 분리해 주는 이젝터부로 구성된다. 본 논문에서는 개발된 지능형 색채선별기용 ARM 프로세서 기반 임베디드 제어기의 하드웨어 구성, 피더부, 카메라부, 이젝터부 간의 통신프로토콜을 이용한 총괄관리 제어와 그래픽 사용자 인터페이스(GUI)를 소개한다.

재래식 버섯균사체메주로부터 제조된 재래식 버섯균사체 된장의 항종양성, 항산화성 및 항돌연변이성을 연구하였다. 항종양성(S-180 세포로 유발한 mouse ascites cancer)에서는 느타리, 영지, 상황, 신령버섯균사체된장이 각각 33, 30, 26, 25% 억제하여 재래식 된장(11%)에 비해 매우 우수한 항종 양성을 나타내었다. 버섯균사체된장은 S. typhimurium TA 98에 대한 IQ와 AFB1에 의한 돌연변이성을 각각 39.7~46.1%, 38.0~39.7% 억제하여 대조된장(32.0, 33.2%)에 비해 항돌연변이성이 우수하였다. S. typhimurium TA 100에 대해서는 IQ와 AFB1의 돌연변이성을 각각 31.9~35.6%, 24.9~30.4% 억제하여 대조된장(27.5, 22.5%)에 비해 항돌연변이성이 좋았다. 항산화성 역시 버섯균사체된장이 대조된장에 비해 효과가 우수하였다. 관련 물질로서 β-D-glucan 함량은 버섯균사체된장의 경우 재래식 된장에 비하여 3~8배, 총 phenol성 화합물과 isoflavone 함량은 느타리버섯균사체된장과 신령버섯균사체가 가장 높았다. Antitumorigenic and antimutagenic activities of the doenjangs prepared from mushroom mycelia-cultured traditional mejus (designated to MTDJ) were investigated using the model of Sarcoma-180-induced mouse ascites cancer, and 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) and aflatoxin B1 (AFB1)-mediated S. typhimurium mutagenicity, respectively. Antioxidative activity of MTDJ was also investigated using the mouse liver microsome system. Mushroom stains used for the preparation of the mushroom mycelia-cultured traditional mejus were Synryeong (Agaricus blazei), Yeonggi (Ganoderma lucidum), Sanghwang (Phellinus linteus), and Neutari (Pleurotus ostreatus). All MTDJs showed the enhanced antitumorigenicities (12% by Synryeong, 13% by Sanghwang, 16% by Yeonggi, and 19% by Neutari), antimutagenicity (6.1~20.8% for IQ and 3.1~10.2% for AFB1), and antioxidative activity (6.6~46.5%), relative to the control doenjang. The β-D-glucan content (0.75~1.71 mg/g) of MTDJs was 3~8 times higher than that (0.22 mg/g) of the control doenjang. Genistein content (769~932 μg/g) of MTDJs was also higher than that (728 μg/g) of control doenjang. The content of β-D-glucan and genistein was not exactly correlated to the antitumorigenicity and antimutagenicity of MTDJs. These results indicate that antitumorigenicity and antimutagenicity of MTDJs were elevated in comparison with the control doenjang, and the observed functions were, in part, derived from β-glucan and/or genistein in the MTDJs.

Because of the magnetic property that attracts magnets to one another, the swallowing of magnets could provoke perforation, obstruction, and formation of fistula in the gastrointestinal tract. Here, the authors describe two cases of gastrointestinal complication caused by swallowed magnets in children. The first case occurred in a 12-year-old boy who swallowed multiple magnetic educational instruments; the patients presented with duodeno-colic and colo-colic fistula. In the second case, a 7-year-old boy swallowed two magnets and developed a jejuno-jejunal fistula associated with perforation of the jejunum. In accidental swallowing of the magnet, especially multiple pieces, the follow-up plain abdominal X-ray film should be checked, and an emergency exploration could be considered.
