      • 조혈모세포이식 후 발생한 주폐포자층 폐렴에 대한 고찰

        주지현,최정현,이동건,백지연,고윤호,이혜정,김세희,신호진,박윤희,박지영,김유진,신완식,김춘추 대한감염학회 2001 감염 Vol.33 No.4

        Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

      • 迎日灣의 ECOSYSTEM 硏究 3. 水溫

        尹伊鏞,朴相來,李東澈,金基台,崔銀珠,安由煥 嶺南大 海洋科學硏究所 1988 Marine Nature Vol.1 No.1

        In order to observe hydrological characteristics in the Gulf of Yoeng-il, measurements of water temperature have been carried out from February to August 1983, and from August 1985 to December 1986. Surface water temperatures are closely linked to air temperature and solar-radiation for all littoral stations. Seasonal and annual variations of all horizontal stations are very similar to one another. Vertical variations of water temperatures for the stations located along the central-line of the Gulf are characteristic (and observed) as thermoclines and thermal stratification in the hottest summer-time (August). It is interesting to note that water column temperature of July and September are rather warmer than August, on account of a cold water mass coming from NE direction. For example, surface temperature in June 1982 was above 19℃, but the water below a depth of about 30m drastically drops to 4℃. It is indicative of invasion of water mass from cold current or deep sea.

        데오도라이트를 이용한 위성체 얼라인먼트 측정에 관한 연구

        윤용식,이동주 한국공작기계학회 2003 한국생산제조학회지 Vol.12 No.6

        A measurement of spacecraft alignment is an important process of spacecraft assembly, integration and test because it is necessary that a ground station controls the precise positions of on-orbit spacecraft by using the alignment data of attitude orbit control sensors(AOCS) on spacecraft. In addition, accuracy of spacecraft alignment requirement is about 0.1°- 0.7°. The spacecraft alignment is measured by autocollimation of theodolite. This paper describes the measurement principle and method of spacecraft alignment. The result shows that all of the AOCS on the spacecraft are aligned within the tolerance quired through the alignment measurement.

        데오드라이트 시스템의 측정 정확도에 대한 연구(Ⅲ) : 시준거리 3m에서 기준자 거리에 따른 측정 정도 A Measurement System Accuracy depending on a Distance of Scale Bar on the Distance 3m between two Theodolites

        윤용식,이동주,윤인진 한국공작기계학회 2005 한국생산제조학회지 Vol.14 No.2

        The theodolite system consists of two theodolites, a scale bar and a target bar. A measurement accuracy of theodolite system is affected by a measurement distance of each equipment. This study was performed for measuring an accuracy when the distance from theodolite to scale bar was changed 2~6 m on two theodolites distance 3 m. The results showed that the measurement accuracy could be ±0.021 mm when the distance from theodolite to target was 2, 3 and 6 m. Specially, it was found that the maximum measurement accuracy was ±0.017mm on theodolite collimation distance 3m and the distance 4 m of the theodolite and scale bar.

        윤희중,문동안,정남주,금명숙,이경식,유실,김영란,한윤수 한국운동역학회 2000 한국운동역학회지 Vol.10 No.1

        본 연구는 임신 40주와 출산후 6주간에 있는 임산부의 보행 동작의 특정을 규명함으로써 이와 관련된 연구자들에게 기초자료를 제공하고자 실시하였다. 이를 위해 임신 4주에 있는 임산부를 대상으로 1차 실험을 실시하였으며 동일한 대상자를 출산후 6주에 2차로 실험하여 자료를 수집하였다. 디지타이징 시 오차를 최소화하고 인체관절점의 분별을 위해 21개의 반사마커를 부착하였다. 10m의 보행주로를 걷는 동안 두 대의 비디오카메라를 이용하여60Hz로 자료를 수집하였으며 동시에 100Hz 지면반력자료를 수집하였다.수집되어진 자료는 DLT 방법을 사용하여 분석하였으며 이의 분석에 Kwon3d 프로그램을 활용하였다. 분석결과 다음과 같은 결론을 얻었다. 1. 임신 40주와 출산 후 6주의 보행 시 지지시간과 스윙시간의 비율이 다르게 나타났으며 보폭과 보간, 활보장은 임신 40주에서 더 큰 값을 보였다. 상체 전경각 역시 임신 40주에서 더 큰 값을 보였다. 힙관절, 무릎관절, 발목관절각도는 S1이 출산후 6주에서 큰 값을 보인반면 S2는 출산전후에 큰 변화를 보이지 않다. 2. 상하지면반력의 경우 FP1과 FP2는 임신 40주보다는 출산 6주에서 큰값을 보였지만 FP3는 임신 40주에서 보다 큰값을 보이고 있었다. 전후지면반력의 경우 출산전과 후 모두 Fy2에서 보다 큰 값을 보이고 있었다. This Study was to investigate kinematical characteristic comparison of the gait pregnant 40weeks and after delivery 6weeks 20´s women and provide the basic data. To accomplish this study, in the first, carry out an experiment with the pregnant women in the pregnant 40weeks on the videotape, and than the second, make an experiment with the kinematic data. Kinematic data were filtered with a low-pass, fourth-order Butterworth filter with an effective cut off frequency of 6Hz. The conclusions were drawn as follows; 1. Floor contact Periods(stance and swing rate) were differed from before and after the delivery and a pregnant 40 weeks was greater than after delivery 6 weeks in the step, width, stride. Also, a pregnant 40 weeks was greater than after delivery 6 weeks in the front angular. And the other angular components were represented similar pattern. 2. In the vertical load, delivery 6 weeks was grater than a pregnant 40 weeks in the FP1(first peak) and FP2(valley). And FP3(second peak)was represent that a pregnant 40 weeks was greater than delivery 6 weeks. Also, in the horizontal shear, Fy2(progressional force)was greater than Fy1(breaking force) about time of the delivery.
