Cloud detection algorithm is being developed as primary one of the 16 baseline products of CMDPS (COMS Meteorological Data Processing System), which is under development for the real-time application of data will be observed from COMS Meteorological Imager. For cloud detection from satellite data, we studied two different algorithms. One is threshold technique based algorithm, which is traditionally used, and another is artificial neural network model. MPEF scene analysis algorithm is the basic idea of threshold cloud detection algorithm, and some modifications are conducted for COMS. For the neural network, we selected MLP with back-propagation algorithm. Prototype software of each algorithm was completed and evaluated by using the MTSAT-1R and GOES-9 data. Currently the software codes are standardized using Fortran90 language. For the preparation as an operational algorithm, we will setup the validation strategy and tune up the algorithm continuously. This paper shows the outline of the two cloud detection algorithms and preliminary test results of both algorithms.

Chung, Yong Gu,Kim, Han Kyeoum,Park, Young-Kwan,Kim, Bong Ryung,Chung, Heung Seob,Lee, Hoon Kap,Lee, Ki Chan,Chu, Jung Wha 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.1

저자는 고려대학교 병원에 입원하여 수술치료를 받았던 17례의 만성경막하 혈종의 환자에서 immunoperoxidase assay를 이용하여 tissue plasminogen activator의 존재유무와 출현정도, 그리고 CT 영상소견과의 연관관계를 추적하였다. t-PA 면역염색은 경막하혈종의 외막 혈관벽(모세혈관과 정맥)에 국한되어 나타났다. CT상 5례에서 mixed density소견을 보였으며 이중 3례는 최근에 출혈이 발생되었다는 중거가 되는 층형태(layering type) 소견이었으며, 이 층형태의 CT소견을 보이는 경우에 t-PA 면역염색의 정도가 뚜렷이 나타났다. t-PA 면역염색이 진하고 뚜렷이 보이는 6례 중 4례에서 CT 영상소견에서 막의 대조강화(enhancement)가 뚜렷이 보인 반면, 면역염색이 약하게 나타난 10례중 3례에서 CT 영상소견상 막의 강화소견을 보였다. CT소견상 종괴효과는 t-PA면역염색이 진하고 넓게 보이는 예에서(4/6) 연하고 국한되게 나타나는 예보다(3/11) 뚜렷이 나타났다. 만성경막하혈종의 혈액양은 t-PA의 염색정도에 따라 비교하여 보면, 염색이 가장 약하고 국한되게 나타난 경우에서 평균 26cc, 중간정도로 염색되는 경우에서 평균 35cc, 가장 진하고 넓게 되는 경우에 평균 61cc로 나타났으나, 임상례의 숫자가 적어 조금더 연구가 필요할 것으로 사료되나, t-PA가 혈종의 증대에 중요한 역할을 하는 요소중의 하나가 될것이라는 추측을 가능하게 한다고 사료된다.

N/A Background: Hepatocellular carcinoma (HCC) is the most common form of primary hepatic carcinoma and is a pressing sociomedical problem in Korea. Of the various solid cancers, HCC is perhaps the most diffcult to treat because of the frequently associated cirrhosis and advanced stage of tumor. In recent years, diagnostic procedures, surgical techniques and various therapeutic modalities other than surgery have been developed and improved. So, the prognosis of these patients may have changed from what it was in the past and it is necessary to establish the criteria for selection of therapeutic modality in indivisual patient with HCC. The purpose of this study was to elucidate the natural history of HCC and the survival rate of patients with HCC in relation to various therapeutic modalities in different stage of chronic liver disease. Method: A total of 1149 patients with HCC seen during the last 20 years were analyzed retropectively. The effects of treatment on survival were analyzed with regard to Child's grading and UICC stage of HCC. Results: In the 265 patients who received no specific treatment, the cumulative survival rates of 6 month and 1 year were 37.5%, 16.6% and the median survival time was 4 months. Survival rates of the surgically treated patients were better than that of other patients groups in comparable Child's grade and UICC stage, Especially, among patients with Child's A or B the actuarial survival rate for surgery was significantly better than that for transarterial chemoembolization. Transarterial chemoembolization gave a significantly better survival rate compared with systemic chemotherapy and no specific treatment in all child's grade and UICC stage. Systemic chemotherapy improved survival as compared with no specific treatment in Child's A or B patients and with UICC stage IV and Child's C with stage IV, patients. The major causes of death were hepatic failure and gastrointestinal bleeding irrespective of treatment modality. Conclusion: Adequate therapeutic modalities according to the severity of liver cirrhosis and tumor stage could improve the prognosis of HCC patients.

Analysis of a High-Tc Superconducting Power Converting System

Yoon, Yong Soo,Jo, Hyun Chul,Park, Young Gun,Lee, Jeyull,Yoon, Kyung Yong,Kim, Ho-Min,Chung, Yoon Do,Chu, Yong,Ko, Tae Kuk Institute of Electrical and Electronics Engineers 2015 IEEE transactions on applied superconductivity Vol.25 No.3

<P>This paper presents the analysis of a high-Tc superconducting (HTS) power converting system, as well as its operational characteristics. The converting system can be used to charge and discharge a magnet made of series-connected pancake coils. The HTS converting system consists of two heaters, a primary copper winding, a secondary HTS winding, a series-connected HTS pancake coil, an iron core and a conventional copper load. In the experiments, the charging and discharging periods were 7.5 and 2 s, respectively. A partial region of the superconducting tape in a secondary HTS winding is switched to a normal region by a buried heating coil. To measure the converting-current with respect to the magnet flux changes, a hall sensor was installed at the center of the pancake coil. In this experiment, the charging-current and discharging-energy reached about 51.7 A and 36.8 J, respectively. The experimental results have been compared with theoretical predictions by using the finite difference method.</P>

N/A Sixty-seven lesions of small hepatocellular carcinoma in 50 patients under 5cm in diameter detected by computed tomography (CT) were reviewed to characterize the CT feature. All 50 patients were studied with a CT-9800 scanner. CT scans were obtained both before and after administration of contrast medium given by bolus injection of 120 ml of meglumine iohatlamate. CT density of the tumor was classified as hypodense, isodense, and hyperdense on the basis of the difference in density between the lesion and the surrounding liver parenchyma. Detectability of small hepatocellular carcinoma on CT scans was divided into three categioies; Good: tumor is noted, and extent of tumor is clearly defined; Fair: tumor is noted, but extent of tumor is not defined; Poor: tumor is not noted. On nonenhanced CT scans, 40 cases (60%) showed hypodense masses and 27 cases (40%) showed isodense masses whereas all cases showed hypodense masses on contrast-enhanced CT scans. On nonenhanced CT scans, 27 cases (40%) were categorized as good, 13 cases (20%) as fair, and 27 cases (40%) as poor while 65 cases (97%) were categorized as good, and 2 cases (3%) as fair on contrast-enhanced CT scans. Additional CT characteristics of small hepatocellular carcinoma were well defined margin (99%), and peripheral hyperdense rim (44%). These results suggest that contrast-enhanced CT scans are better than nonenhanced CT scans in detecting and defining the tumor, and CT might be useful for characterization of small hepatocellular carcinoma.

N/A Seventeen liver masses including eight hepatocellu]ar carcinomas, eight hemangiomas and one simple cyst were studied by magnetic resonance imaging (MRI) with 2.0 Tesla superconductive magnet in order to evaluate the possibility of differential diagnosis between the liver masses by MRI and to analyze the optimal pulse sequence in high field magnet. Identical multislice/multiecho techniques were used in all patients of obtain Tl-and T2-weighted spin echo using TR 500, 1500, 2000 msec and TE 30, 60, 90, 120 msec. MRI could detect liver mass in all cases. Hepatocellular carcinoma tended to have ill-defined margin, inhomogeneous signal intensity, central high signal intensity area and capsule sometimes and showed iso- or high signal intensity on SE 500/30 images and high signal intensity on T2 weighted images obtained with 2000 msec TR and 30, 60, 90 msec TE. Hemangioma tended to have sharp margin, homogeneous signal intensity and no central high signal intensity area or capsule and showed iso- or low signal intensity on SE 500/30 images. Hemangioma also has high signal intensity with prolongation of TR and TE. On T2-weighted images obtained with 2000 msec TR and 60, 90, 120 msec TE, hemangiomas had significantly greater contrast between mass and surrounding liver than hepatocel]ular carcinoma. Simple cyst showed well-marginated homogeneous low signal intensity on SE 500/30 image and increased signal intensity with prolongation of TR and TE. Differentiaion between hemangioma and hepatocellulor carcinoma could possible in 17 cases and MRI may become the procedure of choice for distinguishing hemangioma from hepatocellular carcinoma and may replace the angiography for the diagnosis of hemangioma.
