Toxoplasmosis is a rare but fatal complication in hematopoietic stem cell transplant recipients, usually associated with allogeneic hematopoietic stem cell transplantation (HSCT). We report a case of cerebral toxoplasmosis in a patient with multiple myeloma, following tandem autologous stem cell transplantation. A 55-year-old Korean male presented with weakness in both legs that had progressed to both arms. A magnetic resonance imaging scan of the brain revealed multiple, variablesized ring-enhancing lesions with surrounding edema in the cerebral hemispheres and brain stem. Stereotactic biopsy revealed bradyzoites of Toxoplasma gondii in the brain tissue. The patient received trimethoprim-sulfamethoxazole, followed by pyrimethamine and sulfadiazine, accompanying treatment for progressive multiple myeloma. Cerebral toxoplasmosis should be considered as one of the differential diagnoses in patients with neurologic signs following autologous HSCT.

본 연구에서는 풍동의 활용성과 경제성, 장비설치 및 취급의 용이성등을 고려하여 요구풍속을 결정한 후 확산부, 정체실, 수축부, 시험부등을 설계하고, 제작된 풍동에 대한 성능검사를 실시하였다. 정체부와 시험부 수축비는 9이고 시험부의 단면은 406mm×406mm 이며 길이는 1,200mm 이다. 시험부에서 얻을 수 있는 최대속도는 송풍기 회전수 1,500rpm 일때 36m/sec이다. 송풍기 동력은 19kW 이며 송풍기 형태는 원심형 임펠러를 선택하였다. 시험부의 성능을 검사하기 위해 열선유속계를 사용하여 시험부 출구 단면에서의 속도분포와 난류강도를 조사하였다. 시험부의 속도는 5m/sec 에서 30m/sec 까지의 범위에서 난류강도는 0.5%이고 벽면경계층 두께를 고려하면 유효 단면적은 약 85%이다. 제작된 풍동에 에머리 페이퍼(emery paper) 또는 트리핑 와이어(tripping wire)를 부착한 매끈한 평판과 축대칭 3차원 물체를 장치하여 경계층 속의 흐름이 난류가 되도록 하였고 발생된 난류 경계층의 특성을 분석 하였다. In the present experimental study, the range of wind speed at the test section was determined by considering the availability, economy, installation and handling of the wind tunnel, and diffuser section, settling chamber, contraction section and test section of the wind tunnel were designed and manufactured to satisfy the prescribed wind speed range. Performance of the manufactured wind tunnel was tested according to the normal testing procedure. Contraction ratio of the test section to the settling chamber is 9 and the cross section of the test section is 406mm×406mm and the test section is 1200mm long. The maximum air speed at the test section is 36m/sec for the motor speed of 1500 rpm. A centrifugal type fan is used and the maximum power required is 19kw. The hot-wire anemometer system was employed to test the performance of the wind tunnel by measuring the velocity distribution and turbulent intensity at the exit of the test section. Measured values of turbulent intensity were less than 0.5% for the range of wind speed from 5m/sec to 30m/sec. The available cross sectional area of the test section was about 85%. Flat plate and axisymmetric three dimensional body were used as models to identify the boundary layer characteristics. The boundary layers were triggered by emery paper and/or tripping wire. The characteristics of the generated turbulent boundary layers were analyzed.

Objective: TRAIL(also called Apo-2L) is a member of the tumor necrosis factor(TNF) family of cytokines which induces apoptosis cell death in a variety of tumor cell lines. It mediates its apoptotic effects through one of two receptors, DR4 and DR5, which are members of the TNF receptor family, and whose cytoplasmic regions contain death domains. TNF and Fas ligand induces apoptosis in tumor cells; however, their severe toxicity toward normal tissues hampers their application to cancer therapy. We examed if paclitaxed and/or Apo-2LTRAIL induces apoptosis of cervical cancer HeLa, SiHa, ME-180, and CaSki cells. Mehods : We have demonstrated that paclitaxel and Apo-2L/TRAIL induces apoptosis of cervical cancer HeLa, SiHa, CaSki and ME-180 cell lines in a dose-dependent manner. HeLa, SiHa, ME-180 and CaSki were obtained from American Type Culture Colection. Recombinant Human TRAIL(Chmicon). DR4 and DR5 were purchased from Santa Cruz. Paclitaxel, MTT assay Kit, Acridine orange and Ethium bormide were purchased from Sigma. HeLa and SiHa were grown in DMEM. ME-180 and CaSki were grown in RPMI. Tripan blue stain and MTT assay were done for cytotoxicity. Annexin V-FITC and PI(propidium iodide) flowcytometry for apoptosis assay. DR4 and DR% were expressed by Western Blot. Fluorescent Microscopy used Acridine orange(AO) and Ethium bromide(EB). Results : Importantly, concurrent treatment of cervical cancer cells with paclitaxed and Apo-2L/TRAIL induces significantly more apoptosis than Apo-2L/TRAIL alone. Conclusion : We need further studies which reveals possible therapeutic potential in the women with cervical cancer by suing Apo-2L/TRAIL.

Two cases of primary small cell carcinoma of the ovary occurred. One was a case of 43-year-old woman associated with hypercalcemia and the other was a case of 40-year-old woman with pulmonary type. Ovarian small cell carcinoma of the hypercalcemic type have clinicopathological, immunohistochemical, ultrastructural, and flow cytometric features that from differ from those of small cell carcinomas of the pulmonary type. It is important for therapeutic reasons to distinguish these two types of ovarian tumors from each other and from a variety of malignant small cell tumors that ovary primarily or secondarily. So, we reported these cases with a brief review of the concerned literatures.

The conventional market places are the behavioral space by physical environment and human activity. We discuss ways and means of reviatalizing conventional market. Focused on consumer's aspect and physical improvement of building and equipment. In spite of it's small size, small area. Market is directly connected with daily life of citizen and plays a major role for urban activities and systems. Therefore is necessary to study the physical characteristics related to human activity for improving the physical environment of conventional market. This study base on an assumption that location of industrial classification depend on accessibility and relation with street. The purpose of this study is to analyze relation between street and industrial classification in conventional markets. For the logistic analysis, We investigated type of business, general road width, public land price, connection value, distance from a bus stop, distance between main street and the each store in Daein and Namgwangju markets. The statistical analysis says that 1. In the markets, food stores are located near from the main streets. 2. Clothing stores are located near from the main streets but far from the bus stops. 3. The culture type of business is located far from the main streets. 4. The neighboring facilities are located on the narrow roads and at the lands high in the public price.

金太晩,李啓南 慶熙大學校 1989 論文集 Vol.18 No.-

The change of the dc conductivity during the isothermal annealing of Se_90Sb_10 film with time was studied at 60, 70 and 80℃. The change of the conductivity as a function of time was used as the characteristic quantity of amorphous-crystal transition. The Avrami equation which is represented with the change of log conductivity was applied to expain the process of crystallization of samples, and values of different parameters for the crystallization were evaluated. X-ray diffraction records of samples were used to study the same process. Evaluated values of Avrami exponent of samples were close to 2 or 1, which correspond to the one dimensional growing process. Rate constants k were 2.67 × 10 exp (-4), 1.02 × 10 exp (-3) and 2.22 × 10 exp (-3) for samples annealed at 60, 70 and 80℃, respectively. The activation energy of the crystallization, E, was 2.47 kcal/mole. And then dependence of the radius R of the spherulite crystalline domain on the time, and of the time rate of crystallization, ν, on R were understood.
