        림프종 환자에서의 갈륨, TI-201 그리고 Tc-99m MIBI 섭취의 비교

        천경아,조인호,원규장,이경희,이형우,현명수,이재태,이규보 영남대학교 의과대학 2002 Yeungnam University Journal of Medicine Vol.19 No.2

        Purpose; Ga-67 scintigraphy has been used for the evaluation of tumors, especially lymphoma. Recently, Tl-201 and Tc-99m MIBI were also used to tumor imaging. Tl-201 and Tc-99m MIBI had better physiologic characteristics than Ga-67, so we studied 32 biopsy proven lymphoma patients (male 24, female 8, mean age 46 years) with Ga-67, Tl-201 or Tc-99m MIBI and compared the scan findings. Materials and Methods: Twenty-three of 32 patients were injected 74-111 MBq (2-3 mCi) of Tl-201, before chemotherapy and imaged with dual-headed SPECT (Prism 2000, Picker, USA) at 30 minutes after injection. Delayed images were obtained after 3 hr in 8 patients. Twenty seven of 32 patients were injected 740 MBq (20 mCi) of Tc-99m MIBI and imaged at 30 minutes after injection. 111-185 MBq (3-5 mCi) of Ga-67 was injected in 12 patients and imaged at 48 and 72 hours after injection. Twenty eight patients were diagnosed as non-Hodgkin's lymphoma and others were Hodgkin's lymphoma. Results: Twenty patients were positive on Tl-201 scan and 3 patients showed negative findings. One of these 3 patients, Tc-99m MIBI and Ga-67 scan were positive. Twenty two patients were positive on Tc-99m MIBI scan and 5 patients showed negative findings. One of these 5 patients, Tl-201 was positive and 2 were positive on Ga-67 scan. Ten of 12 patients showed positive findings on Ga-67 scan. The sensitivity of these agents were 83.3%, 87.0% and 81.5% for Ga-67, Tl-201 and Tc-99m MIBI, respectively. The sensitivity was highest in Tl-201 scan, but there were no significant differences among three tests. In this study, there was no significant difference of uptake ratios between early and delayed images of Tl-201. Conclusion: Scintigraphy with Tl-201 and Tc-99m MIBI in lymphoma patients have similar sensitivity with Ga-67.

      • PEO가 첨가된 원형관 난류유동에서의 마찰저항 감소 측정

        이보안,이동원,김신,현명택,천원기 濟州大學校 産業技術硏究所 1998 산업기술연구소논문집 Vol.9 No.2

        The drag reduction by polymer additive is a well-known phenomenon and has been widely studied due to its high usefulness. In this study, in order to obtain the fundamental data on the drag reduction by polymer additive. we measured the friction factors in the polymer added turbulent flow through a circular pipe for Reynolds number ranging 10000-50000. As polymer additive, PEO (polyethylene oxide: molecular weight 4 x l0^(6)) was used. We also performed the experiments varying the concentration of PEO from 3 to 24 wppm to investigate the effect of the PEO concentration on the drag reduction. We observed more than 25% drag reduction under the above experimental conditions and the most effective drag reduction was found at 6 wppm (31% drag reduction).

        On the second year of king Hyo Jong, Lee Dynasty(A.D. 1651), the Yak Ryung Si(originated from Chinese Medicine) beganin Taegu. The market continued until the end of Japanese Occupation, when the controlled economy forced the market to be closed. The year 1957. the market began once again its function as the regular dealer of medicine. In this treatise, we try to report what material we examined and collected about the generally dealt-with crude drugs and its history in a statistic way. Our second aim is to standardize the crude drugs.

      • 전자우편 기반의 인터넷 EDI를 위한 수신 부인방지 및 메시지 반환 기능 설계 연구

        이보경,김명주 서울여자대학교 자연과학연구소 1999 자연과학연구논문집 Vol.11 No.-

        Although S/MIME and OpenPGP are representative protocols used in transferring messages securely on internet environment, they have defects in the internet electronic data interchange (IEDI). In case of S/MIME, the implementation is most difficult due to the restricted usage of public key encryption library. And OpenPGP does not provide receiver non-repudiation and has weak extensibility under public key ring architecture for the authentication. In this paper, we propose a secure message transfer protocol by combining the protocols above in order that it may guarantee us receiver non-repudiation and return-of-content, which are necessary in E-mail based Internet EDI. By using this protocol, we can prevent the message-incurred resource waste in IEDI.

        The purpose of this study was to identify the health status, perception and experience for health education, needs for health education contents in high school students and to select areas and contents of health education curriculum. This study was surveyed 728 adolescents in high school from Sep. 11 1997 till Sep. 26 1997. The results were as follows. 1. For the perceived health status, 65.5% of the boys and 59.8% of the girls answered they were healthy. 18.8% of the boys and 59.8% of the girls experienced disease during the last year. 2. 67.3% of the boys and 71.6% of the girls acknowledge the necessity of health education. 3. For the experience of healty education, girls(82.7%) were reported high experience rates than the boys(51.3%). To the question of the instruction period, boys answered as middle school(84.0%) and girls as high school(77.2%).

        GIS를 이용한 산불발생위험지역 구분

        이시영,안상현,원명수,이명보,임태규,신영철 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.2

        산불로 인한 재해를 미연에 방지하고 피해를 저감하기 위해서는 산불발생위험지역을 사전에 파악하여 예방대책을 세울 필요가 있다. 따라서 본 연구에서는 산불발생인자에 따른 산불발생위험지역을 구분하고자 겸상북도 의성군에서 발생한 산불피해지역에 대하여 임상, 지형 등에 대하여 조사하였다. 조사된 요인들 간 독립성 유무를 상관분석을 이용하여 산불발생과 관련 있는 7개의 주제도를 선정하였으며, 선정된 주제도를 조건부확률과 지리정보시스템을 이용하여 산불발생확률을 계산하였다. 계산된 산불발생확률을 20개 등급으로 지수화하여 산불발생위험지역을 구분하였다. In order to decrease the area damaged by forest fires and to prevent the occurrence of forest fires, we are making an effort to improve prevention measures for forest fires. The objective of this study is to classify hazard regions where forest fires occur based on the factors that contribute to the occurrence of forest fires. Forest fire sites in the Uiseong-gun, Gyeongsangbuk-do were surveyed according to the factors of forest type and topographic characteristics where the forest fires occurred. We used a correlation analysis to determine the forest fire occurrence factors and a conditional probability analysis and GIS to determine a forest fire danger index. The resulting forest fire danger index was used in the classification of forest fire occurrence risk regions.

        산불진화정보 관리를 위한 Mobile GIS 공간 데이터 압축기법 개발

        조명희,이명보,이시영,김준범,권봉겸,허영진 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.2

        최근 무선 인터넷 및 통신기술의 눈부신 발달과 LBS(location based service)개념을 기반으로 한 mobile GIS 기술 개발은 대규모 산불 발생시 정확한 현장 파악과 신속한 상황보고 뿐만 아니라 사고 예방과 분석·평가에 이르기까지 의사결정지원시스템으로 자리를 잡고 있다. 본 연구에서는 지상진화대의 정확한 위치와 이동상황을 실시간으로 파악하여 안전한 진화작업 유도 및 산불진화 환경정보를 제공을 목적으로 mobile GIS 기술 기반의 산불진화정보 관리시스템을 설계하고 네트워크 부하감소를 위하여 '.gci'라는 공간 데이터 압축기법을 개발하여 면, 선, 주기 데이터에 대하여 51~62%의 높은 압축률을 구현하였다. 따라서 대규모 산불 발생시 일어날 수 있는 안전사고를 미연에 방지하고 사고 발생시 신속한 후속조치로 안전하고 과학적인 산불진화 업무를 수행할 수 있도록 하였다. Recently GPS and mobile GIS technologies based on LBS (location based service) have played an important role as DSS (decision supporting system) for domestic forest fire extinguishment policies. In this study forest fire extinguishments information management system based on mobile GIS technique was designed to seize the exact location on wireless network so that it helps to guide the safe and efficient extinguishments affairs and provide the extinguishments environment toward ground fighting teams and the central forest government in real time. Moreover, possibly to operate this system, the foundation technologies by the name of `. gci such as the spatial data compression method, the spatial data transmission method over wireless network and the spatial analysis interface on PDA should be mainly considered. Especially, in this study the spatial data compression method having high compression rate from 51% to 62% for each polygon, line, and point data, without the loss of data was developed.
