Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.

왕겨에 200, 400, 600, 800 및 1000 Gy의 저선량의 감마선을 조사하여 항산화능의 변화를 관찰하였다. 총 페놀 화합물의 양은 무처리구의 경우 0.184 mM를 나타내었고, 200 Gy로 감마선을 조사하였을 때는 0.215 mM로 약간 증가함을 보였으나 이후 차츰 감소하였다. 전자 공여능은 무처리구에 비해 처리구의 경우 조사 선량별로 조금씩의 차이만 있을 뿐, 조사 선량에 대한 왕겨의 전자 공여능은 유의적인 큰 변화 없이 비슷한 활성을 보였다. Fe^2+-ions 킬레이팅 활성은 무처리구의 경우 68.25%를 나타내었으며, 200, 400, 600 및 800 Cy 에서는 각각 86.45, 85.61, 86.65 및 82.84%로서 무처리구보다는 증가함을 보였으나, 1000 Gy에서는 74.67%로 감소하였다. 지질 과산화 억제능은 무처리구에 비해 처리구는 약간의 증가를 보였으나 효과는 미비하였다. We studied the effect of small-dose of γ-irradiation to rice hull(RH) for its antioxidant ability. The RH was treated with 200, 400, 600, 800, and 1000 Gy of γ-ray at 70 Gy/min. Total phenol amount of unirradiated RH was 0,184 mM, after irradiation at 200 Gy it increased to 0,215 mM, while irradiation above 400 Gy up to 1000 Gy decreased that to unirradiated level. The electron donating ability of RH did not show significant change depend on irradiation. The chelating ability for Fe^2+ of unirradiated RH was 68.25 %, while that of 200, 400, 600 and 800 Gy irradiated RH showed 86.45, 85.61, 86.65 and 82.84 % respectively, but, 1000 Gy was decreased to 74.67 %. According to TBARS analyses, inhibition ability of lipid peroxidation by RH was not affected by γ-irradiation.

Craniofacial hyperhidrosis patients complain discormfort due to excessve sweating of head and face. Medical treatment has been used but it's effect is transient and side effects are very common. After introducing of video thoracoscope in 1986, many thoracic surgical procedures have been developed using video thoracoscope. But domestic papers about craniofacial hyperhidrosis have not been existed yet. This study analyzed the effect and patient's satisfaction of T2 symoathicotomy. The degree of sweating change of pre and post T2 sympathicotomy and compensatory hyperhidrosis using linear analogue scale in 15 craniofacial hyperhidrosis patients were analyzed. Craniofacial sweating disappeared after T2 sympathicotomy and patients' satisfactions were high. Compensatory hyperhidrosis appeared on trunk, back, abdomen, thigh and buttock but it's degree was not severe. Therefore T2 sympathicotomy is effective and safe method in treatment of craniofacial hyperhidrosis. But further evaluations are needed on more patients, long time follow-up and compensatory hyperhidrosis.

An induction of spawning by irradiated seawater with ultraviolet rays carried out in the laboratory to conduct fundamental studies on artificial spawning of some cultivated shells, i. e. Haliotis discus, Haliotis diversicolor superlexta, Turbo cornutus, Tapes variegata. Cyclina sinensis. The materials collected from Seongsan-po and Chuza-do during the spiwning season of these species. Stimulus methods for artificial spawning in this experiment were three methods ; UV-rays irradiated seawater used only, the UV-rays irradiation after temperature trestment and UV-rays irradiation after exposure to air. The rate of response and the time required for spawning on the amount of irradiation were observed. In an attempt to artificial spawning by irradiated seawater with UV-rays on the 5 species of shells, the rate of response for spswning in H. discus and H. diversicolor supertexta were effective to induce spawning but weren't in C. sinensis and T. variegata. The most effective discharging time was 4 hours after UV-rays irradiation. As for the amount of stimulus, it was obvious that the spawning rate increased with the amount of the irradiation and reduced the time required for initial spawning. UV-rays irradiation after temperature treatment and UV-rays irradiation after exposure to air were more effective than stimulus by UV-rays irradiated seawater used only. An ability of irradiated seawater caused spawning mediated by photochemical reactions in seawater depending on the enzyme catalyzing oxidative synthesis of prostaglandin. In this experiment, the results suggest that the effect of irradiated seawater with UV-rays to induce artificial spawning is to be recognition.

자동차의 air-bag 장치에 실용될 수 있는 압저항형 단결정 실리콘 가속도센서 칩을 개발하기 위하여 결정 실리콘 미세구조의 제조방법을 확립하고, 단위공정의 검증을 통하여 일괄공정에 의한 PROTO-TYPE 칩을 만드는 기술을 연구하였다. 단결정 실리콘 미세구조는 선택확산법을 이용하여 정확히 선택된 영역에만 air-gap을 형성하여 미세구조의 측면식각을 방지하는 선택확산법에 의한 실리콘 마이크로머시닝 기술로 제조하였다. 일괄공정을 위한 단위공정확립을 위하여 PROTY-TYPE 8빔 브릿지형 가속도 센서를 제조하였다. 제조된 칩의 가속도에 따른 출력전압은 선형성을 나타내고 있으며, 감도는 약 50 ㎶/V·g로 나타났다. 이 감도는 50G용 가속도센서의 사양을 만족하지 못했다. 이는 공정에 의한 문제라기 보다는 가속도센서의 시뮬레이션에 의해 설계한 구조가 이미 원하는 감도에 못 미친다는 것으로 생각된다. 따라서 2차 공정으로 제조될 가속도센서의 파라미터를 SuperSAP 유한요소 패키지를 이용하여 실리콘 미세구조부의 파라미터에 따른 특성을 시뮬레이션하였다. 설계된 50G용 가속도센서의 mass Pad의 반경 및 빔 길이, 빔 폭, 빔 두께, 그리고 mass의 각 파라미터 값은 700 ㎛, 120 ㎛, 5 ㎛, 1.0 ㎎ 이었다. 반도체 공정기술, 관성질량 제조법 및 선택확산을 이용한 마이크로머시닝을 사용하여 일괄공정으로 8빔 브린지형 가속도센서를 제조하였다. We researched the establishment of the silicon microstructure fabrication technique to develop a piezoresistive type silicon acceleration sensor chip and the technique to make a proto-type chip by the verification of the unit-process. Silicon microstructure is fabricated silicon micro-machining by selective diffusion method. This method prevent a side-etching of microstructure because selective diffused region is only formed an air-gap. We fabricated a proto-type 8-beam bridge-type acceleration sensor to establish the unit-process for the batch-process. The output voltage of the chip represented linearity with acceleration, and the sensitivity was about 50 ㎶/V·g. But this sensitivity dosen't satisfy the requirements of a practical acceleration sensor. The cause of this result is assumed not process problem, but the structure designed by simulation isn't suitable already. Threfore, the characteristics of parameters of the acceleration sensor that will be fabricated by 2nd-process is simulated by SuperSAP finite-element package. The determined parameter values of beam length, beam width, beam thickness, mass, and mass radius are 120 ㎛, 5 ㎛, 1.0 ㎎, and 700 ㎛, respectively. We fabricated 8-beam bridge-type acceleration sensor by batch-process using a semiconductor process technique, proof-mass fabrication method, and micromachinig using selective diffusion.
