This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

Toxic oxygen free radicals have been implicated as important pathologic mediators in many clinical disordesrs. Enhandng the intracellular content of antioxidant enzymes can provide means of limiting biological damage caused by oxygen free radicals. Many investigations have examined the potential of various oxyradical scavengers to modulate oxyradical injury. The oxygen free radicals play a role in the pathogenesis of chronic obstructive pulmonary disease. To investigate the pulmonary oxyradical injury and the protective role of antioxidant enzymes, author measured the amount of thiobarbituric acid reactants, the activiteies of antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase) and the sulfhydryl groups in serum and red blood cells from the chronic obstructive pulmonary disease groups and the normal controls. The thiobarbituric acid reactant in chronic obstructive pulmonary disease groups was increased than the controls in both serum and red blood cells, and the superoxide dismutase activity in red blood cells was no statistically difference in both groups. But, the glutathione peroxidase and catalase activities were lowered in chronic obstructive pulmonary disease groups than the controls. The sulfhydryl groups in serum and red blood cells were no statistically difference in both groups. These results suggest that the increased thiobarbituric acid reactant in chronic obstructive pulmonary disease groups mean oxygen radical toxicity, and the decreased glutathione peroxidase and catalase activities may play a role in cellular injury.

박재성,최득린,김기정 순천향대학교 1992 논문집 Vol.15 No.4

Bronchography has been classically considered the most accurate procedure by which to evaluate the presence, severity and distribution of bronchiectasis. Recently, the ability of computed tomography (CT) for imaging bronchiectasis was demonstrated. The authors performed a comparative study of HRCT and bronchography. Fifteen consecutive patients who were clinically suspected of having bronchiectasis, were investigated (4 unilateral, 11 bilateral). Fifteen HRCT and 26 bronchography was performed and total of 185 bronchopulmonary segments were evaluated. Segment-by-segment comparison of the 2 studies for the detection of ectatic bronchi were evaluated by 2 radiologists. The results were as follow; 1. The diagnostic concordance rate between the 2 modalities was 87.7%. 2. The sensitivity and specificity of HRCT were 88.1% and 87.5% for bronchography. concordance rate between the 2 modalities was 90.3%. 3. The rate of false negative study of HRCT was 5.5% for bronchography, 3 localized bronchiectasis(33.3%) and 3 mild ectatic change (33.3%) were missed on HRCT. 4. The rate of false negative study of bronchography was 42.9% for HRCT, 9 incomplete opacification of distal bronchi on bronchography. 5. On comparative study of bronchiectatic patterns, 5 varicose bronchiectasis were misdiagnosed as cystic bronchiectasis on HRCT. The HRCT showed a high diagnostic concordance rate with bronchography. Therefore HRCT should be considered as a promising diagnostic modality for detection of bronchiectasis.

Renal artery stenosis is the one of causes of hypertension in a small percentage of all patients but is only anatomical cause that can be treated by means of surgery and percutanecous transluminal angioplasty. Angiography is the golden standard for diagnosis of renal artery stenosis, but a little invasive. With the advent of abdominal Doppler ultrasonography, renal artery stenosis could be diagnoed noninvasively. The experienced hands appears to be valuable in the doppler examination, ut some investigators consider it almost useless. The authors studied the effect of stenosis of renal artery on the downstream intrarenal blood flow, a snare was placed around renal artery in 12 rabbits and compressed to create stenosis while Doppler ultraonographic curve and flow index were obtained from main renal and interlobar arteries by means of placement of 10-MHz curved linear tranducer directly on the surface of kidney. The Doppler measurements were compared with the percentage of stenosis on angiograms. The results were as follow: 1. Ten satisfactory angiograms and Doppler ultrasonograms were obtained. 2. Three renal arteries were created stenosis below 70% (Group A), Seven were above 70% (Group B). 3. The ranges of RI (resistance index) were 0.61-0.86 (mean 0.78±0.154) at main renal arteries, 0.57-0.85 (mean 0.77±0.231) at interlobar artery. The range of PS (peak systolic velocity) were 13.1-28.8 (mean 21.65±4.445) m/sex at main renal artery, 5.2-18.1 (mean 11.74±4.095) m/sec at interlobar arteries. The RI of rabbits were higher than those of human (mean 0.58±0.05). 4. The range of RI in stenotic arteries of group B were 0.45-0.74 (mean 0.57±0.143) at main renal artery, 0.52-0.65 (mean 59±0.051) at interlobar arteries. The range of PS were 11.2-21.3 (mean 15.04±3.755) m/sec at main renal arte교, 5.7-11.3 (mean 8.24±2.056) at interlobar artery. The difference were statistical y significant (P=0.0302), but without remarkable change in group A. 5. Doppler ultrasonographic curve during progressive compression of renal artery showed dampened systolic waveform and diagonal upstroke at main renal arteries (71.4%) and interlobar arteries (85.7%) in group B, but without remarkable change in group A. 6. Release of the arterial compression caused higher than normal peak systolic velocity initially, at main renal arteries (42.9%) and interlobar arteries (28.6%). but the curve of all rabbits returned to normal within 5 minutes. The Doppler ultrasonographic index and curve were not changed on follow up Doppler ultrasonogram at 5 min. 10 min. 30 min. and 1 hour. The change of the systolic curves that compressed experimentally is identical to change in the pulsus tardus and parvus waveforms seen in both acute and chronic severe renal artery stenosis in humans, can helpul for the diagnosis of renal artery stenosis and the effects of treatment by percutaneous tranluminal angioplasty and surgery.

Left ventricular outflow tract obstruction and systolic anterior motion of the mitral valve after myxomatous mitral valve repair is due to excess tissue of mitral valve among numerous other factors. A patient who had myxomatous mitral valve and acute mitral regurgitation due to chordae rupture was admitted for mitral valve repair. The hospital course of the patient was not significantly different compared to other patients. On the 40th postoperative day, the patient experienced syncope and came to ER. The patient showed severe left venthcular outflow tract obstruction and systolic anterior motion of mitral valve. The patient was treated medically and was discharged with normal echo findings. We report this case with brief review of related literatures.

항공기 노즈 랜딩기어의 쉬미 해석

황재혁,김두만,남창호,임경호 한국항공대학교 1993 論文集 Vol.31 No.-

본 연구를 통하여 항공기 노즈 랜딩기어의 동안정성을 지배하는 운동방정식을 유도하고, 이를 수치적으로 해석하는 프로그램을 개발하였다. 개발된 프로그램은 어떠한 초기조건 및 파라메타의 변화가 착륙장치의 동안정성에 미치는 영향을 해석하는데 매우 유용한다. 노즈 랜딩기어의 운동 방정식을 해석한 결과, 동적 불안정을 유발시키는 중요한 파라메타를 결정하였고, 이 파라메타들을 적적히 조절하면 지배장정식은 안정된 해를 갖게 된다. 그 중 대표적인 파라메타는 K?,K₃,C이다. 해의 두번째 특징으로 발산하지 않는 해 가운데서 쉬미(shimmy)현상을 나타내는 해가 있다. 쉬미현상은 비선형 시스템에서 나타나는 리미트사이클로서 고정된 진폭과 주파수를 갖고 진동하는 해를 뜻한다. 이러한 쉬미현상을 해석한 결과, 조향계통의 프리플레이(free play)가 쉬미 발생에 결정적인 원인이 됨을 확인 하였다. In this study, the equations of motion of an nose landing gear system for shimmy analysis has been derived and then the equations have been solved by numerical method. The developed program in this study is useful to evaluate the effect of the initial conditions and parameters of the nose landing gear on the its dynamic stability. It has been found that the parameters such as K?K₃,C? play the most prominent role on the dynamic stability of the nose landing gear. Shimmy is a kind of limit cycle which can be occurred in the nonlinear dynamic systems. Shimmy has been analyzed numerically in this paper. It turns out that the free play in the steering system is the most important factor to generate shimmy.
