강회일,정대영,윤문길 한국항공대학교 경영연구소 2000 경영연구 Vol.7 No.1
이 논문은 정부에서 중점 육성하고자 하는 30대 정보통신핵심분야에 대한 기술 및 시장전망을 토대로 기술개발 핵심분야와 경쟁력 확보분야로 나누어서 유망 수출품목을 선정하고, 각 품목에 대한 유망시장 탐색 및 진출전략을 살펴보려는 것을 주요 내용으로 삼는다. The confluence of information and telecommunications technologies is creating explosive changes in the various of industries. Since some major industries in information and telecommunication areas have boosted up the national economic growth, it is needed to identify such industries being supported for improving competitiveness. In this paper, we consider an evaluation model to identify some major industries in information and telecommunication areas by using DEA. Applying the model, we can obtain the relative efficiency, we can select several major industries among alternative ones for improving their competitiveness by some effective strategies. Recent advances in information technologies have paved the way for an explosive growth in the area of information and telecommunication industries.

In this paper, we consider an evaluation model to identify some major industries in information and telecommunication areas by using DEA.

Rhodopseudomonas sphaeroides의 Uptake Hydrogenase에 관한 연구
최명재,강대길 서강정보대학 1990 論文集 Vol.9 No.-
We study the effect of uncouplers, which inhibite phosphorylation and inhibitors, which block electron transport in specific sites of electron transport chain, on hydrogenase activity from whole cell Rhodopseudomonas sphaeroides. In the presence of 10μM 2,4-DNP and CCCP as uncouplers, and 10μM rotenone which blocks between NADH₂ and ubiquinone, 5μM antimycin A which blocks between cytochrome b and c in the electron transport system, the uptake hydrogenase activities change into 95%, 102%, 96%, 37% of normal hydrogenase activity in resting cell. These result show that the hydrogenase coupling which ubiquinone in electron transport chain and ATP make an important role in hydrogenase synthesis.

The environment to which a packaged-product is exposed, during handling and transportation, very often includes temporary storage. In the interest of conserving warehouse cube, packaged-products are stacked upon one another to a height which far exceeds that possible in a railcar, truck-trailer, aircraft or other conveyance. the hight to which the height to which a packaged-product may be stacked will vary depending upon the warehouse ceiling height-seldom over twenty feet. This procedure for expirimental covers testing of packaged-products weighing under 100 pounds when prepared for shipment. The BASIC requirements of this procedure consist of vibration and drop tests-which must be performed in that sequence.

Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

We report here on an unusual case of mucinous cystic tumor that was associated with endometriosis in the cecum. A 45-year-old woman was admitted to the hospital due to her 5 day history of right lower quadrant abdominal pain with a mild fever. A laparotomy was performed under the clinical impression of the tubo-ovarian abscess. A relatively well defined a multi-locular cystic mass (8.0×8.0×7.0 cm) filled with white-to-yellow thick mucoid material was found in the wall of the cecum. The right ovary and fallopian tube showed marked fibrous adhesion to the external surface of the cecal mass. A right hemicolectomy and salpingo-oophorectomy were performed. Histologically, the tumor was similar to those of ovarian borderline mucinous tumor, the intestinal type, and the mucinous epithelium of the tumor was merged with the endometriotic epithelium and stroma. On immunostaining, the CK20 positive mucinous epithelium was well demarcated from the CK7 endometriotic epithelium. This is the first case of low-grade mucinous cystic tumor intimately associated with intestinal endometriosis in the cecum.
