홍성민,정인균,이준우,김성준 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.1

본 연구는 경안천 하류구간(13.8㎞)을 대상으로 SMS의 RMA2 모형과 SES2D 모형을 이용하여 2002년 경안관측소의 최대홍수위를 기록한 8월 7일의 수리분석을 실시하였다. RMA2 모형을 적용하기 위하여 RIMGIS 데이터의 하천측량자료를 이용하여 입력자료로 활용하였으며, 생성돈 지형자료를 2차원 유한요소망으로 변환하여 모형을 수행하였다. 본 연구에서는 부정류 상태의 모의를 적용하였으며, 모형에 민감하게 반응하는 인자에 대해서는 선행 연구에서 실시한 민감도 분석결과를 고려하였고, 기타 입력인자는 통계연보 및 하천정비계획서를 참고하였다. 또한 대상하천에 SED2D 모형을 적용하여 홍수사상에 대한 하천의 하상 변동에 대한 모의를 실시하였으며, 대상 하천의 홍수시 유속은 0.05~3.85㎧의 분포로 상류와 하류의 큰 차이를 보였고, 하상변화는 0.0003~0.0135m가 발생하였다. The purpose of this study is to analyze various hydraulic characteristics using SMS(Surface Water Modeling System) RMA2 model. It is based on 2-D finite element method, River reaches (13.8㎞) from Gyeongan gauge station to the inlet of Paldang lake was selected. Finite element was made by RINGIS Data, and the analysis of river-changes was operated by unsteady flow. The sediment concentration and bed change was simulated using SED2D model. This River's velocity was distributed that 0.05~3.85㎧ and bed change was changed about 0.0003~0.0135m.

고광준,최은숙,홍성우 大韓口腔顎顔面 放射線學會 1999 Imaging Science in Dentistry Vol.29 No.1

Objectives: The purpose of this study was to aid in the prediction of tumor cell tolerance to radiotherapy and/or chemotherapy. Material and Methods: Human epidermoid carcinoma A-431 cell lines were irradiated by 2, 4, 6, 8, 10Gy at a dose rate of 210cGy/min using Co Irradiator ALDORADO 8 and then were exposed to bleomycin or cisplatin at concentration of 2㎍/ml for 1 hour. The viable cells were determined for each radiation dose and/or each drug at the 4th day and cell surviving curves were obtained using semiautomated MTT assay. Results: The surviving fraction after irradiation of 2Gy was 0.99, and there was not significant difference of surviving fraction in comparison with the control group on A-431 cell line(P>0.05). But there were significant differences of surviving fractions at doses of 4, 6, 8, 10Gy in comparison with the control group(P<0.05). The cytotoxicity of bleomycin or cisplatin was significantly different in comparison with the control group on A-431 cell line (P<0.05). And the cytotoxicity of cisplatin was greater than that of bleomycin on A 431 cell line (P<0.05). There were significant differences of surviving fractions after irradiation of 2, 4, 6, 8, 10Gy with bleomycin or cisplatin in comparison with each group of irradiation only on A-431 cell line(P0.05). There were significant differences of surviving fractions between the groups of irradiation with bleomycin and cisplatin at doses of 2, 4Gy(P<0.05), but there were not significant differences of surviving fractions at doses of 6, 8, 10Gy on A-431 cell line(P>0.05).(J Korean Oral Maxillofac Radiol 1999:29:325-337)

박형준,이철형,최명수,김경호,이성로 木浦大學校 應用科學硏究院 2001 應用科學硏究誌 Vol.1 No.-

Smart antennas technique is the scheme that focuses the signal on the desired user using array antennas. Therefore, the scheme can dramatically improve performances in conventional mobile communication systems. The scheme is the newest technique for beamforming. Its specific function combines antenna arrays with digital signal processing techniques that can control signal direction. Now, the scheme is known as the future generation core technique in communication provider communities. In this paper, we propose two dimensional rake receiver based on blind schemes in smart antennas and then compare the performance of the proposed scheme with that of the conventional scheme. Computer simulation results show that the proposed scheme outperforms the conventional scheme.

삼각측량 시스템을 이용한 3-D 형상 복원

The 3-D shape use to effect of movie, animation, industrial design, medical treatment service, education, engineering etc... But it is not easy to make 3-D shape from the information of 2-D image. There are two methods in restoring 3-D video image through 2-D image; First the method of using a laser; Second, the method of acquiring 3-D image through stereo vision. Instead of doing two methods with many difficulties, I study the method of simple 3-D image in this research paper. We present here a simple and efficient method, called direct calibration, which does not require any equations at all. The direct calibration procedure builds a lookup table(LUT) image and 3-D coordinates by a real 3-D triangulation system. The LUT is built by measuring the image coordinates of a grid of known 3-D points, and recording both image and world coordinates for each point; the depth values of all other visible points are obtained by interpolation.

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).
