  • We report a boy with acute pancreatitis without abdominal pain accompanied by hepatic hematoma and massive ascites due to unperceived trauma. The case was difficult to diagnose with image study and the level of amylase. Strong suspicion of pancreatic injury based on mechanism of injury and clinical evaluation would be required to avoid a delay in diagnosis.

  • Kasabach-Merritt syndrome is a rare thrombocytopenic consumptive coagulopathy associated with a giant hemangioma. We experienced a case of unexplained ascites with thrombocytopenia in a 32 week premature infant. An exploratory laparotomy was performed to determine the cause of the refractory ascites and thrombocytopenia. An intestinal hemangioma was found, but, surgical removal was not performed due to the extensive involvement. Hemangioma was confirmed by SPECT (single-photon emission computed tomography) and the thrombocytopenia was treated with steroid therapy. It is recommended that hemangioma of the visceral organs should be suspected when unexplained thrombocytopenia and disseminated intravascular coagulopathy persist.

  • Childhood tuberculous peritonitis is difficult to diagnose especially in cases without pulmonary involvement. It may present as mechanical ileus, perforation, simulating acute appendicitis, enterocolitis or intusussception. Early diagnosis in children may be difficult, largely because of variable vague symptoms and nonspecific signs. Surgery has often been required for pathologic confirmation. We have experienced a case of tuberculous peritonitis presenting with abdominal pain, abdominal distension and persistent high fever in a 10-year-old boy who was diagnosed by explo-laparotomy and pathologic confirmation from biopsy specimen from omentum. The patient was treated with antituberculous drugs and recovered uneventfully.

  • The purpose of this study is to examine and propose to improve the features of a simple keyword search box and faceted navigations of KOLIS-NET operated by the National Library of Korea. A record group of '2011-2020 (776)' under 'Publication date' facet, out of 3,702 records retrieved from a search of '김훈', were examined. Major findings are as follows: (1) Five facets including 'Format', 'Publication date', 'Subject', 'Language' and 'Country' are used to limit search results only in the first step, and multiple facets cannot be simultaneously used; (2) With 'Publication date' facet formed in the span of ten years, a separate publication year cannot be identified; (3) 'Subject' facet based on KDC limits the results only in broad subject classes without sub-facets; (4) Under 'Format' facet, a special format such as large print texts cannot be identified; (5) Without 'Author' facet, authors cannot be identified; and (6) 'Publication date missing', 'Language missing', and 'Miscellaneous subject' record groups cannot be clicked and displayed, a navigation to-and-fro between a brief list and bibliographic records is not smooth, etc. Therefore an application of multiple facets in all stages of limiting the search result, a construction of sub-facets for 'Publication date' and 'Subject' facets, an accurate description and coding of 'General Material Designation', etc. are suggested to improve KOLIS-NET's faceted navigation.

Effects of Ascitic and Pleural Fluids from the Cancer Patients on the Immune Responses of Mice to Sheep Red Blood Cells (암환자(癌患子)의 복수(腹水) 및 늑막액(肋膜液)이 마우스의 면양적혈구(緬羊赤血球)에 대(對)한 면역반응(免疫反應)에 미치는 영향(影響))

  • Nonspecific suppressions of the immune responses have been reported to occur in the cancer-bearing patients. The mechanisms responsible for these immunosuppressions remain unclear but some investigators suggested that the immunosuppressions may result from immunosuppressive factors exudated from tumor masses. This study was undertaken to evaluate the in vivo effects of ascitic and pleural fluids from patients with cancers metastatic to peritoneum or pleura on the immune responses of mice. Non-cancerous ascitic and pleural effusions were used as controls. The ascitic fluids from hepatomap atients and pleural fluids from pulmonary carcinoma patients decreased both the delayed-type hypersensitivity and the antibody formation only when these were injected before antigenic stimulation. Control effusions exerted no effect on the immune responses to mice. These results suggested that cancerous fluids suppressed the immune responses by affecting the afferent arc of the immune system.

  • Congenital biliary atresia with progressive sclerosis of the intra- and extra-hepatic duct system occurs in 1 : 10,000 live births, and has a poor prognosis with an expected survival of less than 5 years. Etiology of biliary atresia is unclear, however, it is believed a genetic or developmental cause. The clinical characteristics include pronounced jaundice, hepatosplenomegaly, pruritus, steatorrhea, xanthomas, growth retardation, portal hypertension, bleedings, ascites and respiratory infections. Oral manifestations have seldom been reported in patients with biliary atresia, but there may be enamel hypoplasia, delayed tooth eruption, and green teeth. Early diagnosis and surgical intervention have decreased morbidity. returned growth and development to normal and improved the prognosis for survival. Authors report the clinical and radiologic characteristics, proper managements about two cases with biliary atresia.

  • Subjective sentences express opinions, emotions, evaluations and other subjective ideas relevant to products or events. These expressions sometimes can be seen in only part of a sentence, thus extracting features from a full-sentence can degrade the performance of subjective-sentence-classification. This paper presents a method for improving the performance of a subjectivity classifier by combining two classifiers generated from the different representations of an input sentence. One representation is a sentimental phrase that represents an automatically identified subjective expression or objective expression and the other representation is a full-sentence. Each representation is used to extract modified n-grams that are composed of a word and its contextual words' polarity information. The best performance, 79.7% accuracy, 2.5% improvement, was obtained when the phrase-level classifier and the sentence-level classifier were merged.

  • Serous effusions have been most commonly associated with ascites, pericardial effusion, and heart failure. But, they have been considered to be an unusual form of complication in hypothyroidism and pleural effusion, which has been observed as an isolated finding in hypothyroidism is apparently rare and complete analysis of these types of hypothyroid-associated pleural effusions has yet not been described. We report a case of hypothyroidism associated with unilateral pleural effusion in a 77 year-old male patient who was improved through levothyroxine sodium with brief review of the literature.

  • 최근 애매성이 수반되는 정보를 Zadeh는 멤버쉽함수(membership function)를 이용하여 새로운 정보처리 방식으로서 퍼지이론을 제안하였고, 그후 의료계에서도 퍼지이론을 도입한 진단법들이 제안되었다. 회전기계의 이상진단법으로는 주파수득점법(Point counting method), 퍼지역연산법(Inverse method of fuzzy theory)등이 보고되고 있으며, 저자들도 퍼지이론을 이용하여 구름베어링의 결함진단, 회전기계의 간이 이상진단법등을 보고하였다. 이들은 주로 진동주파수의 스펙트럼 데이터 만을 이용하고 있고, 다른 많은 데이터를 복합적으로 이용할 수 없다. 이 때문에 주로 소규모 문제의 간이진단에서는 효과적이나 진단대상이 복잡하고 대규모로 되면 보다 정확한 원인 추정이 곤란하게 된다. 또한 수치데이터만을 취급할 수 있으므로 진동전문가가 진단에 이용하는 각종의 수치화 될 수 없는 데이터(언어적인 정보)가 취급될 수 없다. 따라서 이들의 진단법은 개략적인 진단은 가능하나 상세한 원인까지는 진단할 수 없는 단점이 있다. 회전기계의 이상판단시 참고가 되는 각종 정보로는 주로 진동진폭의 크기, 진폭과 위상의 변화, 진폭의 변화, 진동파형, 진동벡터의 시간변화 등이 있고, 이들은 수치적으로 표현할 수 있는 계량데이터와 판단의 경계가 불명확한 언어정보(범위데이터)로 나눌 수 있다. 후자는 애매성(fuzziness)을 많이 포함하고 있으며, 엄밀히 측정되는 수치데이터에서도 퍼지성을 가지고 있다. 이러한 언어적인 정보의 애매성을 퍼지추론에서는 [수치적 진리치](numeric truth)와 [언어적 진리치](linguistic truth)의 개념으로 표현하게 되었다. 수치적 진리치는 확실함의 척도를 [0,1] 사이의 수치를 이용하여 표현하고 있으며, 이 수치는 소견의 확실도로서 가능성을 표현한 것이다. 예를 들면, 진동진폭 스펙트럼상에 2X 성분이 상당히 크게 나타나 정렬불량의 가능성이 0.7 정도라고 판정하는 것 등은 이러한 수치적진리치를 이용하는 방법이다. 그러나 상기의 수치적 표현만으로는 확실도를 한개의 수치로서 대표하게 하는 것은 진단의 정밀도에 문제가 있을 것으로 생각된다. 따라서 언어적진리치가 도입되어 [상당히 확실], [확실], [약간 확실] 등의 언어적인 표현을 이용하여 애매성을 표현하게 되었다. 본 논문에서는 간이진단 결과로부터 추출된 애매한 진단결과중에서 가장 가능성이 높은 이상원인을 복수로 선정하고, 여러 종류의 수치화할 수 없는 언어적(linguistic)인 정보ㄷㄹ을 if-then 형식의 퍼지추론으로 종합하는 회전기계의 이상진단을 위한 정밀진단 알고리즘을 제안하고 그 유용성을 검토한다.
