심근경색증의 급성기에 시행한 경피적 관동맥 스텐트 삽입술의 효과
이남호 關東大學校醫科大學醫科學硏究所 1998 關東醫大學術誌 Vol.2 No.1
최근 들어 여러 연구보고에서 심근경색증의 급성기에 스텐트 삽입술을 시행하여 풍선확장술만을 시행한 경우에 비해 시술 후 6개월 내의 주요 심장합병증 및 재협착율이 현저하게 감소됨이 보고된바있다. 본 연구에서는 1992년 9일 1일터 1991년 10월 10일까지 세브란스병원 심장내과에 내원하여 심근경색증의 급성기에 경피적 관동맥성형술을 시행받은 38명의 환자들을 대상으로 하여 풍선확장술만 시행한 군과 스텐트를 시술한 군으로 나누어 관동맥조영술 소견 및 임상적 경과 등을 전향적으로 분석하였다. 분석결과 비록 적은 대상환자수로 인하여 통계적 유의성은 관찰되지 않았으나 스텐트 시술군에서 풍선확장군에 비해 관동맥 재협착율이 훨씬 낮은 것을 알수 있었으며 병원내 생존에 유일하게 의미 있는 지표는 경색원인 관동맥의 재관류 여부였다. 따라서 최근의 여러 연결결과 및 본 연구의 결과를 고려할 때 향후 심경색증의 급성기에 스텐트 삽입술이 매우 중요한 치료로서 자리잡을 것으로 사료된다. Primary balloon angioplasty in acute myocardial infarction has been shown to result in lower rates of mortality, recurrent MI, and stroke compared with thrombolysis. However, recurrent ischemia and early reocclusion of the infarct-related vessel occur in 10-15% of patients and late restenosis in the first 6 months remains high. Recently two prospective randomized trials comparing stenting with balloon angioplasty in acute stage of myocardial infarction showed that balloon angioplasty followed electively by coronary stents can be used as the primary modality for acute myocardial infarction, reducing in-hospital adverse events, and improving late outcome compared with balloon angioplasty alone. In this study, we retrospectively reviewed the angiographic findings and clinical outcomes of 38 percents with primary angioplasty in acute myocardial infarction, Although there was no statistical significance due to small study population, restenosis rate in the stent group was lower than in the balloon angioplasty group(18% versus 50%). This study demonstrates that primary stenting in acute stage of myocardial infarction can be applied safely and effectively, resulting in a lower rate of restenosis compared with balloon angioplasty.

1990년 1월부터 1997년 9월까지 연세대학교 의과대학 영동세브란스 병원에 내원한 비소세포성 폐암환자에게 수술 전 항암제 투여, 흑은 방사선 치료와의 병행요법으로 그 효과를 분석할 수 있었던 15명의 환자를 대상으로 수술시 연령, 성별, 수술 방법, 병기 변화, 병용 치료요법에 대한 반응, 수술 후 합병증, 사망원인 등을 조사하였다. 15명 중 처음 진단시 제 IIIA 기는 6명, 제 IIIR 기는 9명이었으며, 편평 상피암 13명 선암 2명이었고 14명이 남자이었다. 이들의 중앙 연령은 56.2세 이었으며 개흉술은 모두에게서 시행되어 졌으며, 병리학적 완전 관해가 3명(20.0%)이었고, 유도요법에 대한 전체 반응률 46.7%이었다. 개흉술 당시 병기절하(Downstaged)는 10명(53.3%)에서 나타났다.

李東喆 관동대학교 1999 關大論文集 Vol.27 No.1
I make a study for the si-jo(시조) of Kwandong(관동) district matters. The name of place or interest place in Kwandong appear on the si-jo. In this case, Youngdong(영동)distric is superior than Youngsu(영서)distric. and natural materials are superior than human workes. These appearances are cause by Keumgang(금강)mountain. Matters of Keumgang mountain occupy thiry percent in the ancient si-jo, and seventy percent in the recent si-jo. But Eight Beautiful Spot of Kwandong(관동8경) are inferior in numbers than Keumgang mountain. Thema of affectionate rememblances are notable in the si-jo.

大學의 정책결정과정과 오차수정:절차적 합리성을 중심으로
鄭仁和 관동대학교 1995 關大論文集 Vol.23 No.2
This paper intends to analize the two different policy-making strategies : substential rationality and procedural rationality. In this paper, the author emphasizes the limit of decision-making process and suggests the least error producing policy making strategy ; procedural policy making strategy. To insure the policy error-correction mechanism, the author introduces the notion of redundancy, loosely-couppled organization. In addition, this paper interlinks the essence of liberalism to the strategy for the procedural rationality. With the theoretical basis, the author tackles to solve the problem of Kwandng University for its development. In this regard, the author suggests the University to reform the old style policy making habits and to introduce some new policy making mechanism including the introduction of reward-punishment system and concent oriented policy making process.

석탄폐석의 활용에 관한 실험적 연구 : 도로 토공재를 중심으로
박흥규,김남옥 관동대학교 1994 關大論文集 Vol.22 No.2
Statistics has it that coal refuses discarded every year through our coal mines amount to approximate 7 million tons,some 3 to 4 hundred tons piled on each coal mine.Recent years have witnessed the ever-in-creasing problems of environmental pollutions such as stream pollution,forest damage,and public nuisances,which are allegedly caused by coal refuses. In this regard, a few people interested are quite worried about the continual collapse of mining businesses. This we are able to attribute to the industrial rationalization policy of the government during 1990's. Here we consider that the radical method of mass consumption of coal refuses lies in the good use of them as construction materials. This,we are sure,will enable us to clear up a difficult problem of gathering aggregate,to expect to obtain the result of curtailment of expenditure in exploiting the coal mines with the rise-up of added value,and also to make activated community development of coal mine areas which are still stagnant,and also to better the environment in terms of the proper use of refuses. Thus we attempt to investigate the geotechnical characteristics of coal refuses, examining the possibility of the improvement method of soft soil for the strength increase.

간기능 평가에 있어서 개인용 컴퓨터를 이용한 간체적의 산정
김경식 關東大學校醫科大學醫科學硏究所 1998 關東醫大學術誌 Vol.2 No.1
Measurements of the whole liver volume have used for the assessment of preoperative functional reserve in cirrhotic patients. The equipment of personal computer and peripherals have been developed and widely used. We easily calculated pure liver volume excluding tumor volume using program on personal computer and investigated the relationship between pure liver volume the conventional parameters such as Child-Pugh score and IGG R15. The whole liver volume were 1634.3±764.4cm, volume of tumor were 322.7±97.0㎤ and the pure liver volume excluding tumor volume were 1311.7±402.5㎤. The comparison true liver volume with above mentioned two indexes were as follows: (1) The true liver volume were 1389.1±565.6㎤ in patients with Child-Pugh points 5 and 1243.8±196.6㎤ in patients with a value of IGG R15 less than 10% and 1501.8±571.3㎤ in patients with a value of IGG R15 above 10%, respectively. Although there were limitations for using the pure liver volume as index of liver reserve function the measurement for liver volume with this method is simple and accurate and further studies and more cases would be needed.
