Intestinal ischemia is divided into three categories, namely, acute mesenteric ischemia (AMI), chronic mesenteric ischemia (CMI), and colonic ischemia. AMI can result from arterial or venous thrombi, emboli, and vasoconstriction secondary to low-flow states. It is an urgent condition which can result in high mortality rate. The predominant causative factor of CMI is stenosis or occlusion of the mesenteric arterial circulation, and it is characterized by postprandial abdominal pain and weight loss. Surgery is the treatment of choice for intestinal ischemia. However, it has been recently reported that percutaneous transluminal angioplasty with stent placement and/or thrombolysis is an effective therapy in various types of mesenteric ischemia. We report six cases of mesenteric ischemia which were successfully treated by percutaneous angioplasty, and review the literature from South Korea. (Korean J Gastroenterol 2011;57:243-248)

This study examines academic research trends and the change of patterns by analyzing researches related to hospital management registered in Korea Citation Index(KCI) from 2010 to 2014 and offers basic information for interests and future research demands in the field of hospital management As research subjects, a total of 694 published articles were selected. It``s to analyze them by dividing into research topics, methods and author.s characteristics, and to present them by classifying the period into 2010-2011, 2012-2013, 3rd quarter of 2014 since there was no significant difference in the result between adjacent years. As a result, Korean Journal of Hospital Management has accounted for the highest published rate year after year. In the research topic analysis, it showed a decreasing trend in these research topics as medical marketing and patient satisfaction which became the biggest issue in 2010-2011 significantly were lower in 2014, but an increasing trend in job satisfaction, job stress, labor administration and workforce productivity. The most frequently cited keywords were hospital employees, job satisfaction, organizational commitment, job stress, turnover intention. According to the research method analysis, the survey was the most popular method for data collection. However, Interview and medical records as data sources showed a decline trend. As analysis methods, multivariate analysis of quantitative methods was most used. Finally, as a result of analyzing main author.s characteristics, the ratio of the authors belonging to health administration and nursing departments of the academic world increased gradually. In the regional distribution, organizations in Seoul are most common, those in DaeguㆍGyeongbuk areas, foreign organizations showed a tendency to decrease. This is the first study to examine the annual trend on hospital management-related research issues among articles published in domestic journal and we found qualitative and quantitative advances in hospital management research filed.

When visually impaired people purchase beverage cans, they experience a lot of inconvenience because sufficient information is not provided in Braille on the can. In order to alleviate this inconvenience, this paper proposes a method using Inception v3 to recognize 20 types of beverage cans from images captured with a mobile phone. To implement the proposed system, a total of 6835 images were obtained by directly capturing beverage cans at convenience stores and vending machine. As a result of implementation and verification using Tensorflow and pytorch, accuracy of 94.28% and 95.99% were measured, respectively.

Background: As a reform plan of health care system, Accountable Care Organization (ACO) has became an object of attention in the United States after Patient Protection and Affordable Care Act was enacted. ACO is a group of various health care providers and pro-vide coordinated care to its assigned beneficiaries. If ACOs improve the quality level and reduce the cost of care, they can get finan-cial incentives. Under the discussion for a quite long time and demonstration projects, ACO has been established. We aimed to anal-ysis and discuss the history, policy mechanism, contents, status and outcomes of ACO. Also, we intended to suggest political impli-cation Korean health care system with regard to ACO. Methods: We searched the articles related ACO in PubMed and selected several available papers about ACO. Total 56 studies were reviewed and categorized three parts; demonstration projects for formation of ACO, policy mechanism and agenda, empirical re-sults of ACO performance. Results: As a result, establishment of ACO was successful partly in the US. It seems to be due to various project and pilot test for veri-fication in the long time. The empirical effect of ACO was also identified in a few study but it needs more evidences to judge its posi-tive effect. Conclusion: In Korea, there are arguments for the application of ACO. However it is difficult to implement a ACO by different politi-cal conditions between Korean and US. Nevertheless ACO proposed us the necessity of paradigm shift in our health policy and could be significant to national policy orientation in the future.

Purpose: Low molecular weight heparin (LMWH) is safe and effective in the treatment of acute coronary syndrome (ACS) and venous thromboembolism. Compared with unfractionated heparin (UFH), it is known to have less bleeding tendency in the general population. However, it is not certain whether bleeding complications are decreased by LMWH in patients with renal failure. We postulated that the use of LMWH may lead to increase in bleeding tendency in patients with renal dysfunction. Methods: We conducted a retrospective study in 486 hospitalized patients who were diagnosed as cerebral infarction or ACS, and treated with enoxaparin or nadroparin from January 2008 to December 2009. Bleeding complications were compared in 3 groups according to estimated glomerular filtration rate (GFR 60, 30-59, and <30 mL/min/1.73m ≥ 2). Age, hypertension (HTN), diabetes mellitus (DM), smoking and usage of antithrombotics were examined and the relationship of these variables with bleeding tendency was analyzed. Results: Compared with group I, the frequency of total bleeding complications increased in patients with group II (p=0.002) and III (p=0.005) regardless of adequate dose reduction. Multiple logistic regression analysis after adjustment for age, HTN, DM, and usage of antithrombotics revealed that decreased GFR groups [odds ratio (OR) of group II was 5.79 (95% confidence interval (CI), 1.23-29.97; p=0.042), OR of group III 5.92 (95% CI, 1.22-27.61; p=0.029)] and DM [OR of DM 7.88 (95% CI; 1.46-46.32, p=0.026)] were two independent factors which affect major bleeding. Conclusion: These findings suggest that renal insufficiency, even if it is mild, could affect major bleeding complications in the use of LMWH.

Purpose: Rapid and accurate assessment of impaired consciousness is very important, especially for critically ill patients. Therefore, the Glasgow coma scale (GCS) has been widely adopted in the assessment of adult and pediatric comas. But the GCS should not be used for small children who show various normal responses according to their developmental stage. Therefore, the objectivity of pediatric coma measurements was verified by applying the modified GCS to patients in a pediatric intensive care unit (PICU) at a university hospital in Korea. Methods: The level of consciousness was evaluated for 200 cases who were admitted to a PICU from July 4, 2009 to September 18, 2009 and could show a verbal response, with our modified GCS for children. In addition, and we confirmed the frequency analysis and Kappa statistics with SPSS/WIN 17.0. Results: Kappa statistics which show inter-observer reliability were very good for all components (eye opening, verbal, and motor score) and was good for total GCS scores. Conclusion: It is concluded that our modified GCS is reliable. Therefore, reliable assessment for the level of consciousness is clinically practicable if enough training is supported.

Sclerosing mesenteritis is a rare inflammatory disease of the bowel mesentery. It produces tumor-like masses of the mesentery composed of varying degrees of fibrosis, chronic inflammation, and fat necrosis. It has been described variously as fibrosing mesenteritis, retractile mesenteritis, mesenteric Weber Christian disease, and systemic nodular panniculitis. The etiology and pathogenesis of the disease are as yet unknown, but autoimmune disorder, previous abdominal surgery, trauma, and ischemia could play a role. The clinical features include abdominal pain, vomiting, diarrhea, and constipation. Occasionally, patients with this condition may present with bowel obstruction. Rarely, It can be associated with other idiopathic inflammatory disorders such as retroperitoneal fibrosis, sclerosing cholangitis, and orbital pseudotumors. We report a case of idiopathic sclerosing mesenteritis with retroperitoneal fibrosis in a 58-year-old man. (Korean J Gastroenterol 2011;58:221-225)
