목적 : 심도자 사용 시술과 관련된 좌주간부 관상동맥박리에 대한 적절한 치료는 아직 확실히 정립되지 않은 상태이다. 이에 본 연구는 좌주간부 관상동맥 박리에 대한 스텐트 삽입술의 단장기 임상결과를 후향적으로 분석하였다. 방법 : 좌주간부 관상동맥 박리에 대한 치료로 즉각적인 스텐트 삽입술을 시행하는 것이 안전하고 효과적인 방법임을 가설하였고, 이러한 즉각적인 스텐트 삽입을 시행한 10명의 환자를 대상으로 단장기적 임상경과를 의무기록 고찰과 전화 면담을 통해서 평가하였다. 결과 : 전체 환자 모두 처음부터 좌주간부 관상동맥에 유의한 협착을 가진 환자는 없었으며, 8명의 환자는 심도자의 조작으로 인한 박리가 발생한 경우였고(진단적 혈관 조영술 중에 3명, 유도 도자 조작 중에 5명), 나머지 2명은 다른 병변에 스텐트 삽입시술을 하는 중에 박리가 발생하였다. 이 10명의 환자에서 모두 즉각적인 스텐트 삽입술이 시행되었고, 4명의 환자에서 시술 도중 혈압 저하로 Intra-aortic Ballon Pump (IABP)를 장착하였다. 모든 환자에서 성공적으로 스텐트가 삽입되었고, 병원내 사망은 1명도 없었다. 6개월 추적 관상동맥 조영술은 8명의 환자에서 시행되었다. 혈관 조영상의 재협착(직경 협착 50% 이상)은 8명 모두에게서 관찰되지 않았으며, 퇴원 후 평균 31±25개월의 추적관찰 결과 주요 심장사건은 1건도 발생하지 않았다. 결론 : 비록 대상 환자가 적은 연구였지만 좌주간부 관상동맥 박리에 대한 스텐트 삽입술은 기술적으로 안전하고 빠르게 시행 할 수 있으며, 훌륭한 단장기적인 치료 효과를 보여준다. Background : The optimal treatment of patients with left main coronary artery (LMCA) dissection during catheter-based procedure remains uncertain. We retrospectively analyzed the acute and long-term results of bail-out stenting for LMCA dissection. Methods : In cases with significant LMCA dissection occurring during catheter-based procedure, prompt stent implantation may be safe and associated with favorable clinical outcome. We evaluated the acute and long-term results of bail-out stenting for LMCA dissection occurring during catheter-bases procedure in 1- patients. Results : Initially, there was significant stenosis of LMCA segment in these patients. Catheter-induced dissection occurred in 8 patients (during diagnostic angiography in 3 patients and guiding catheter manipulation in 5 patients). Two patients suffered dissection in the setting of stent deployment in other vessels. Therefore, bail-out stenting LMCA dissection was performed in a total of 10 patients. In 4 patients, hypotension developed and intra-aortic balloon pump was placed during procedure. Stents were successfully deployed in all patients. There was no in-hospital mortality. Six-month angiographic follow-up was performed in 8 patients. Angiographic restenosis(diameter stenosis 50%) was not observed in all patients at follow-up study. During a mean follow-up of 31±25 months after hospital discharge, there was no major adverse cardiac event (death, myocardial infarction, and target lesion revascularization). Conclusion : Bail-out LMCA stenting is technically feasible, and showed good acute and long-term results in a small series of patients.

Iago의 世界

李鐘歡 群山大學校 1984 論文集 Vol.7 No.-

My subject is the world of Iago. I mean simply the imaginative environment that Othello asks us to enter when we read it. Great plays, as we know, do present us with something that can be called a world, a microcosm - a world like our own in being made of people, actions, situations, thoughts, feelings, and much more, but unlike our own in being perfectly, or almost perfectly, significant and coherent. In a play's world, each part implies the other parts, and each lives, each means, with the life and meaning of the rest. However, there appear many Vices in Morality Plays and Interludes, who contain both foolish qualities of comedy and devilish ones of tragedy. The comic qualities of Vice succeeded to Shakespeare's Fool characters and the wicked ones of Vice showed the way to the Iago. Shakespeare's Fools satirize on the follies in aristocratic society. In other words, the world of Romance is the very target on which they'd give an criticism. But to carry their jokes a little too far would develop into the negation of everything and the love of evil for evil's sake. So Iago does a 'motivelsss malignity' as Vice torments other characters without any hatred. Iago's world is devil's one while Othello's world is Romance's one. The conflict which these two worlds make in colliding with each other is the theme of the tragedy Othello.

SHS 공정에 의한 텅스텐 산화물로부터 고순도 텅스텐분말 제조

99% Pure tungsten powders were prepared by self-propagating high temperature synthesis (SHS) process from a mixture of ammonium paratungsten(APT) and Mg powders. The concurrently formed MgO in the product was leached with an HCI solution. The optimum molar ratio of APT to Mg is 1:46 and the compaction pressures range from 2000 to 4000 psi. The propagation velocity and combustion temperature increased, as the compact diameter increased. The weight change and elongation of the SHS product were affected by compaction pressure on the green pellet. The tungsten product had a purity of 99% and mean size of 2∼3 μm.

중수로형 원자로에서 방출되는 사용후핵연료 다발을 안전하게 운반할 목적으로 CANDU 수송용기에 대한 방사선차폐해석을 수행하였다. 핵연료의 연소도는 7,800MWD/MTU, 냉각기간은 5년으로 하여 ORIGEN2 코드로 방사선원을 구하고 이것으로 핵연료 378다발을 운반할 수 있는 수송용기의 차폐체 두께변화에 따른 선량율 영향을 비교하였다. 계산은 ANISN과 DOT4.2 코드를 사용하였으며, 해석결과 최적의 차폐구조를 선정하였으며, 또한 IAEA 및 국내원자력법의 수송법규에 명시된 정상수송 및 가상사고조건에 따른 차폐해석을 수행하여 CANDU 수송용기의 안전성을 입증하였다. A shielding analysis of the shipping cask for transporting the CANDU spent fuel bundles has been studied. Radiation source term has been calculated on spent fuel with burnup of 7,800 MWD/MTU and 5 years cooling time by ORIGEN2 code. The shielding calculation for the cask capable of transporting 378 bundles of CANDU spent fuel has been made by use of 1-D ANISN and 2-D DOT 4.2 codes. As result of analysis, the optimum shield thickness of cask was obtained. And it is proved that the safety in radiation shielding under normal transport and hypothetical accident conditions is confirmed to satisfy the allowable values specified in IAEA Safety Series No. 6 and the Korean Atomic Law.

형광등제조사업장 수은폭로근로자들의 요중 N-Acetyl-β-Glucosaminidase activity에 관한 연구

The periodic evaluation of workers exposed to mercury has some limitations in detectin early changes of renal dysfunction with existing methods of blood or urine examination because of low sensitvivity. The urinary N-acetyl-β-glucosaminidase(NAG) activity test has been recommended as sensitive method to detect early renal dysfunction by many foreign researchers. So urinary NAG activitiy in urine of workers who were exposed to mercury at a fluorescent lamp manufacturing factory was determined to study early renal dysfunction of the workers. Fifty textile workers and six healthy members of a research institute served as reference subjects. The results were as follows : 1. The correlation between urinary NAG and mercury was statistically significant(p(0.001), and the correlation coefficient was 0.4449. 2. The high reference value of urinary NAG activity in reference subjects was 360μMole methyluMbelliferone /mg of creatinine. 3. When the mercury levels in urine were grouped as under 50μg /1, 50-300μg /1 and aboVe 300μg /1, the percentage of test subjects whose urinary NAG activities were greater than the high reference value(370μmole methylumbelliferone/mg of creatinine) were 9.5%, 40.9% and 57.1%, respectively. However, this increasing trend was not statistically significant when the test subjects were limited only to the group exposed to mercury(30.8%-40.9%-57.1%, p=0.52) . 4. About 43% of subjects whose urinary mercury were above 300μg /1 had urinary NAG actiVity below 360MU μM /mg Cret. This result suggests that urinary mercury level is not a absolute indicator in diagnosis of mercury poisoning and a sensitive method which can detect the early health effects of mercury need to be developed.

Shakespeare의 The Merchant of Venice試論 : Centered on portia Portia를 中心으로

李鍾歡 群山大學校 1983 論文集 Vol.6 No.-

Although conventionally placed among the comedies of Shakespeare, The Merchant of Venice might be called 'a problem play.' A 'problem play' is one which raises certain difficult questions, but leaves the audience in radical indecision as to how those issues should be resolved. In Shakespeare's play, many important questions are raised - the nature of love and friendship, the relation of man to money, the morality of lending money at interest, the plight of Christian and Jew, the limited value of the civil law. All of those subjects are treated in the play, but few are completely resolved. The themes of The Merchant of Venice to have been claimed by N. Coghill or F. Kermode are the irony of justice and mercy, and the Christian teachings about judgement, redemption and mercy. I am quite with them on that the questions of justice and mercy, judgement and love are important in the play, but it is often looked upon that how Shakespeare deals with these problem is very critical and ironical. The snobbery and hypocrisy of the Christians in Venice, ad the cruelty of Antonio to Shylock, which is not suitable as a royal merchant have been already pointed. Therefore this paper is discussed centered on Portia who has been comparatively overlooked.
