        Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

      • 시멘틱 웹 환경에서의 온톨로지 기반의 정보검색

        정은경,김영민,변영철,이상준,박경린 濟州大學校 基礎科學硏究所 2003 基礎科學硏究 Vol.16 No.2

        온톨로지는 시멘틱 웹을 구현하기 위한 이론이다. 온톨로지는 웹자원의 효과적인 검색, 통합, 재사용을 위한 새로운 기술이고 사람과 이질의 응용 시스템 간에 지식을 공유하고 재사용하기 위한 방법을 제공한다. 온톨로지의 역할은 특별한 개념을 명세화하는 것이다. 도메인과 일반적인 온톨로지는 정보와 지식 시스템을 분석하고 디자인하는 측면에서 공유, 통합, 재사용될 수 있다. 본 연구는 제주도의 숙박과 관광정보를 위한 온톨로지를 디자인하는데 목적이 있다. 그리고 제안된 온톨로지 기반으로 인터넷 웹 검색 시스템을 만드는데 목적이 있다. 본 연구에 의해 클라이언트가 사용하는 표현은 다르지만 뜻이 같은 동의어에 의해 같은 결과를 얻을 수 있다는 것을 알게 되었다. Ontologies are formal theories that are suitable for implementing the semantic web. Which is a new technology that attempts to achieve effective retrieval, integration, and reuse of web resources. Ontologies provide a way of sharing and reusing the knowledge among the people and the heterogeneous application systems. The role of ontologies is that of making explicit specified conceptualizations. In this context, domain and generic ontologies can be shared, reused, and integrated in the analysis and design stage of information and knowledge systems. This study aims to design an ontology for juju lodges and tour, and build an Internet web retrieval system based on the proposed ontologies. This study found that we can take the same result for synonym that cilent use.

        소비자-브랜드 관계가 확장된 브랜드 평가에 미치는 영향

        박은아,김태형,성영신,강정석 한국소비자학회 2004 소비자학연구 Vol.15 No.4

        본 연구에서는 소비자-브랜드 관계(BRQ)가 확장된 브랜드 평가에 미치는 영향력을 알아보고, 또한 소비자-브랜드 관계의 강도에 따라 확장된 브랜드에 대한 평가시에 적정한 불일치성 효과(MIE)가 나타나는지 검증하고자 하였다. 연구 결과 소비자-브랜드 관계 강도에 따라 확장된 브랜드에 대한 태도와 구매의도는 다른 것으로 나타났으며, BRQ의 여섯 개 하위차원 중에서 확장된 브랜드 평가에 직접 영향을 미치는 것은 관계의 질 차원과 사랑과 열정 차원인 것으로 분석되었다. 한편, BRQ가 높은 집단에서 확장된 브랜드에 대한 적정한 불일치성 효과는 나타나지 않았으며 속성 유사성 효과도 나타나지 않았다. 반면 BRQ가 낮은 집단에서는 기존의 연구들과 마찬가지로 속성 유사성에 따라 확장된 브랜드에 대한 평가가 다른 것으로 분석되었다. 본 연구의 결과는 확장된 브랜드에 대한 평가에는 기존 브랜드와의 BRQ가 중요하며, 관계가 강할 때에는 속성 유사성 정도에 관계없이 확장 브랜드에 대해 호의적인 평가가 일어날 수 있음을 시사하고 있다. We examined how consumer-brand relationship affects the evaluation of extended brands. Specifically, we investigated the effect of the sub-dimensions of consumer- brand relationship quality (BRQ) on the evaluation of extended brands and the existence of moderate incongruity effect (MIE) in high BRQ consumers. The results shows that the BRQ sub-dimensions have different effects to the attitude toward the extended brand and purchase intention to the extended brands. We tested MIE in high BRQ consumers, the result did not support of moderate incongruity effect in brand extension. It means that strong BRQ consumers evaluate positive to the extended brands regardless of the degrees of the product attribute similarities. For the weak BRQ consumers, the product attribute similarities with parent brands affect their attitudes and purchase intentions of extended brands in the same result of the previous study. These results showed that the strong consumer-brand relationship is key important factor to the favorable evaluations to the brand extensions. Finally, theoretical and practical implications and limitations of this study were discussed.

        조은택,박용관,김진호,강정원,천영욱,전익섭,박유환,전춘해 조선대학교 1995 The Medical Journal of Chosun University Vol.20 No.1

        Malignant histiocytosis, originally described in 1939 as histiocytic medullary reticulosis by Scott and Robb-Smith, is a rare histiocytic proliferative disorder that often shows an acute onset and used to progress to death within a few months. This disorder characterized clinically by fever, generalized weakness, lymphadenopathy and hepatosplenomegaly, and shows a variable range of pancytopenia. Extranodal involvement is common, with an incidence ranging from 50% to as high as 90%, skin involves8ment was noted in 10% to 15%. Typical skin lesions were mainly founded in extremity. i.e. erythematous papule and nodule occasionally become to necrosis and ulceration. We experienced one case of malignant histiocytosis in a 46-years-old female. The major clinical findings are fever, malaise, hepatosplenomegaly and erythematous skin lesion. In the laboratory study, pancytopenia is noted on the peripheral blood. And also aggregation of many atypical histiocytes were shown on skin and bone marrow biopsy. So we reported one related case with malignant histiocytosis as well as reviewing literature .

      • Selenium 부족 식이가 흰쥐 간장에 미치는 영향

        김은희,이현기,양영철,차인준 인제대학교 1990 仁濟醫學 Vol.11 No.3

        Se 부족에 의하여 랫트의 체중과 사료 섭취량은 감소되었으며 혈중 LDH, GOT와 간장조직의 glutathion 농도는 정상보다 증가되었다. Se 부족군의 조직학적 소견은 간세포의 공포화 변성, 간조직의 PAS 반응 저하, LDH 활성화 감소 및 ACP 활성의 증가를 나타내었으며, rER의 분절화 현상 및 감소와 mitochondria의 종창 등이 관찰되었다. The objective of this study was to determine the effect of Se-deficient diet on the weight gain, chemical changes in plasma and microstructural change of liver in rat. Rats were divided into 2 diet groups (Se-deficient diet) and control diet and sacrificed after 21days of feeding. Levees of LDB, GOT, GPT of Plasma arid glutathione of liver were determined and light microscopic and electron microscopic observation of ret liver were performed. Total weight gaits (P<0.05) and feed efficiency radio (P<0.001) were significantly lower in Se-deficient group than in control group, whereas the levels of plasma LDH (P<0.001) and GOT (P<0.05) were increased significantly in Se-deficient group. Furthermore, the levels of total glutathione (P<0.01) and reduced glutathione (P<0.001) showed significant increase in Se-deficient group. Light microscopic observations showed that cytoplasmic blooning degeneration and pyknosis of nuclei were often found around portal canal of Se-deficient group by H-E straining. PAS staining also showed weakly positive reaction around central area, whereas PAS negative reacting cells were often observed around portal canal of Se-deficient group. Histochemical staining skewed that cytochrome oxidase activity were very active in both groups, whereas LDH activity was significantly decreased arid ACPase activity was significantly increased in Se-deficient group. Electron microscopic observation showed that the number of rER were decreased and the blooning degeneration of rEr was often observed in Se-deficient group. Mitochondria with mayeline figure arid wooly density were also observed in Se-deficient group. Light microscopic observations showed that cytoplasmic blooming degeneration and pyknosis of nuclei were often found around poral canal of Se-deficient group by H-E staning. PAS staining also showed weakly positive reaction around central area, whereas PAS negative reacting cells were often observed around portal canal of Se-deficient group. Histochemical staining showed that sytochrome oxidase activity were very active in both groups, whereas LDH activity was significantly decreased and ACPase acclivity was significantly increased in Se-deficient group. Electron microscopic observation stewed that the number of rER were decreased and the blooning degeneration of rER was often observed in Se-deficient group. Mitochondria with myeline figure and wooly density were also observed in Se-deficient group.
