Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

혈액 투석 환자에서 중심정맥 협착에 대한 스텐트 삽입술 : Wallstent Placement

임대승,노상필,이유선,정승현,김보영,이정우,강정아,김정희,이민수,정준용,최시완,정진옥,성인환,이강욱,신영태 충남대학교 의과대학 의학연구소 2002 충남의대잡지 Vol.29 No.1

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

정진우,박순옥,김윤지 韓國敎員大學校 敎育硏究院 2009 敎員敎育 Vol.25 No.3

이 연구의 목적은 중학생들의 공간능력에 따른 지하수에 대한 이해를 알아보는데 있다. 공간능력 상·중·하 수준의 각 학년 2명씩 총 18명의 중학생들이 그린 지하수에 대한 그림과 면담 자료로부터 지하수에 대한 이해를 지하수의 정의,지하수의 형성,지하수의 존재,지하수의 이동으로 구분하여 분석하였다. 다수의 학생들이 지하수라는 단어의 뜻을 추측하여 지하수를 정의하였고,지하수의 형성 과정에 대한 이해가 부족하였으며,지하수가 이동하지 않는 호수와 물탱크 형태로 존재한다고 생각했다. 연구 결과에서 대부분의 학생들이 지하수의 개념에 대한 이해의 어려움을 보였으며,공간 능력에 따른 이해도의 차이는 크지 않았다. The purpose of this research is to analyze the middle school students' understandings of groundwater according to their spatial ability. Students' drawings of groundwater and interviews were used for the analysis. The results of students' understandings of groundwater were classified into four categories; definition, process of forming, existent shape, and movement of groundwater. Many of the students defined the groundwater by guessing the word 'underground'. They lacked in understanding the process for the occurrence of groundwater. They also thought that the groundwater didn't move, but is stored in the shape of lakes or water tanks. Research results show that most of the students have difficulty in understanding the concept of groundwater, and that their understanding of groundwater don't have large differences, even though they have different levels of the spatial sensibility.

解止還給金請求權에 관한 硏究

鄭鎭玉 한국기업법학회 2001 企業法硏究 Vol.8 No.-

Die Arbeit befaβt sich mit dem Anspruch auf den Ru¨ckkaufwert aus einem Lebensversicherungsvertrag und den interessenkonflikten, die sich dann ergeben ko¨nnen, wenn der Versicherungsnehmer diesen Anspruch durch Abtretung oder Verpfa¨andung verfu¨gt. Sie beschra¨nkt sich auf die Behandlung der auf das eigene Leben des Versicherungsnehmers abgeschlossen Kapitalversicherung und die Ero¨rtung der unentgeltlichen, fu¨rorglich motivierten Begu¨nstigung. Im Rahmen der jeweiligne Interessenkonflikte wird die Rechtslage bei der Versicherung mit unwiderruflicher und widerruflicher Begu¨nstigung dargelegt. Der Versicherungsnehmer kann einen zu seinen Lebzeiten auftretenden Geldbedarf durch Ru¨ckgriff auf den Zeitwert seiner Lebensversicherung nur befriedigen, wenner sich deren Spar-bzw. Kreditsicherungsfunktion zunutze machen kann. Dies setzt voraus, daβ er imstande ist, die vertraglichen Gestaltungsechte auszuuβben bzw. u¨ber die geldwerten Versicherungs-anspru¨che durch Abtretung oder Verpfa¨ndung frei zu verfu¨gen. Diesem interesse des Versicherungsnehmers an freier Negoziabilitavt widerstreitet das interesse des Begu¨nstigten, vor Eintritt des Versicherungdfalls in den Genuβ der Ru¨ckkaufssumme (Ru¨ckkaufswert) zu gelangen. Die Durchsetzung dieses Versorgungsinteresses erfordert eine durch Verfu¨gungen des Versicherungsnehmers nicht zu beeintra¨chtigende Rechtsposition des Dritten. Im Arbeit wird ero¨rtert, ob und inwieweit die Verfu¨gungsmacht des Versicherungsnehmers durch die Einra¨umung einer unwkderruflichen bzw. widerruflichen Bezugsberechtigung eingeschra¨nkt wird. Die Gla¨ubiger des Versicherungsnehmers, die regelma¨Big durch inreβig durch ihre Leistungen zumindest mittelbar die Pra¨mienzahlungen ihres Schuldners ermo¨glicht haben, sind daran interessiert, jederzeit in den geldwerten Anspruch auf den Ru¨ckkaufwert vollstrecken zu ko¨nnen. Diesem Befriedigungsinteresse sind das Versorgungsinteresse des Begu¨nstigten und das Interesse des Versicherungsnehmers an der Bereitstellung einer eigenen Altersversorgung entgegengesetzt. Die Durchsetzung dieser Versorgungsinteressen erfordert, dem Begu¨nstigten und dem Versicherungsnehmer eine vor Gla¨ubigerzugriffen geschu¨tzte Rechtsposition einzura¨umen. Im Arbeit wird ero¨rtert, ob und ggf. inwiewert die Vollstreckungsmo¨glichkeiten der Gla¨ubiger des Versicherungsnehmers im Hinblick auf Versorgungsfunktion der Lebensversicherung eingeschrankt werden.

특허권침해의 판단기준으로서 균등론

정진옥 동의대학교 지방자치연구소 2004 공공정책연구 Vol.20 No.-

Once a claim has been interpreted by a court, an accused product or process can be found to infringe a patent claim in one of two ways: either literally or under the "doctrine of equivalents". Literal infringement will be found if an accused product or process meets each and every limitation of a properly interpreted claim. Under the doctrine of equivalents, infringement may also be found even if each claim limitation is not literally met, so long as the differences between the accused product or process and the claimed invention, with respect to each claim limitation, are insubstantial as determined by the Judge. The doctrine of equivalents is designed to protect inventors from those who might otherwise make unimportant and insubstantial changes and substitutions in a patent. This doctrine involves Patent Court tripartite test under which infringement may be found if the claimed and accused devices perform substantially the same overall function, in substantially the same way, to achieve substantially the same overall result.

保險事故發生前의 保險給付請求權의 讓渡

鄭鎭玉,鄭容相 釜山 外國語 大學校 1998 外大論叢 Vol.18 No.2

Die vorliegende Arbeit befaβt sich mit den interessenkonflikten, die sich dann ergeben konnen, wenn der Versicherungsnehmer Rechte und Asnpruche aus einem Lebensversicherungsvertrag auf einen Dritten Ubertragt im Rahmen einer Sicherungszession oder Vollzession. Es soll hierbei nicht nur untersucht werden, weiche Voraussetzungen fur eine wirksame Abtretung vorliegen mussen, sondern vielmehr auch die Rechtsposition der Beteiligten nach erfolgter Abtretung dargestellt werden. Im Rahmen der jeweiligen Interessenkonflikte wird die Rechtslage bei der Versicherung mit unwiderruflicher und widerruflicher Begunstigung dargelegt. Der Versicherungsnehmer kann einen zu seinen Lebzeiten auftretenden Geldbedarf durch Ruckgriff auf den Zeitwert seiner Lebensversicherung nur befriedigen, wenn er sich deren Spar-bzw. Kreditsicherungsfunktion zunutze machen kann. Die Vorschrift des §731Abs. 2 Koreanischen Handelsgesetz setzt voraus. daβer imstande ist, die vertraglichen Gestaltungsrechte auszuuben bzw. uber die geldwerten Versicherungsanspruche durch Abtretung frei zu verfugen. Diesem interesse des Versicherungsnehmers an freier Negoziabilitat widerstreitet das interesse des Begunstigten, bei Eintritt des Versicherungdfalls in den Genuβder versicherungssumme zu gelangen. Die Durchsetzung dieses Versorgungsinteresses erfordert eine durch Abtretung des Versicherungsnechmers nicht zu beeintrachtigende Rechtsposition des Dritten. Im Arbeit wird erortert, ob und inwieweit die Rechtsposition des Begunstigten durch die Abtretung von Rechte und Anspruche aus einem Lebensversicherungsvertrag eingeschrankt wird. In Hinblick auf die Frage, welche Voraussetzungen fur eine wirksame Abtretung vorliegen mussen, eine Abtretung der Versicherungsanspuche ist dem versicherer gegenuber nur erst dann wirksam, wenn sie der Verfugungsberechtigte angezeigt hat. Die Rechtsfolgen einer Anzeige der Abtretung regelt die Vorschrift des §450 Koreanischen BGB. Keine Ubergabe des Versicherungsscheines verlangt fur die Wirksamkeit der Abtretung. Fur die Frage, wie die Abtretung des Versicherungsanspruches druch den Versicherungsnehmer auf die Rechtsstellung auswirkt, ist zwischen Vollzession und Sicherungsabvtretung, zu unterscheiden. Bei der Vollzession im Gegensatz zur Sicherungszession soll dem zessionar nach dem Willen der Parteien die eingeschankte Glaubigerstellung hinsichtlich der Versicherungsleistung zugewendet werden, weil die dem Versicherer anzuzeigende Abtretung regelmaβig den endgunstigung beinhaltet. Nach meiner Meinung geht dergegenuber davon aus, auch die Sicherungszession einen widerruf der Bezugsberechtigung bedeutet und daβdieser Widerruf mit Anzeige bei dem Versicherer wirksam wird, ohne daβ insoweit eine ausdruckliche Erklarung uber den Widerruf der Bezugsberechtigung abzugeben ist. Eine ganz andrere und noch weitergehende Frage ist es, ob die Sicherungszession einen endgultigen Widrruf der Bezugsberechtigung enthalt oder ob der Widerruf nur fur die Dauer der Abtretung wieder auflebt. Anders als bei der Vollzession ist mit der Sicherungszession regelmabig kein endgultige Widerruf der Bezugsberechtigung verbunden, vielmehr ist davon auszugehen, dab nach erfolgter Ruckabtretung das ursprunglich Bezugsrecht wieder auflebt. Sofern der Versicherungsnehmer fur die Leistung im Erlebens oder im Todefall unwiderruflich einen Bezugsberechtigten bezeichnet hat, erwirbt dieser bereits mit der Benennung ohne weiteres Zutun den Anspruch gegen den Versicherer.

라이센스契約 當事者의 權利·義務

정진옥 한국상사판례학회 2004 상사판례연구 Vol.16 No.-

An intellectual Property license is contractual agreement between two parties, on of whom has title to complete bundle of rights to the property(licensor) and another who has acquired the use of some of those rights(licensee). There is an infinite variety of possibilities as to how those rights can be allocated between the parties and as to how compensation will flow from one to the other. Generally, license agreements begin with identification of the parties involved in the transfer and a recitation of their intentions. The important elements of a basic license agreement are as follows. Exclusivity grants rights to a single party for the defined field of use and territory. If this is the intent of the parties, this should be stated. Sole licensee can be looked at as a variation of exclusivity. in this case, licensee is the only other party granted the defined rights while still allowing the licensor rights to practice the invention. Licensee fees can also be required by a license agreement, whereby the licensee give the licensor a payment for the license. The fee can represent an advance against which future royalty obligations will be charged or it can simply represent a form of "signing bonus" for the licensor. Improvements and grantbacks can be valuable property developed in the future. The licensee may want to receive the latest version of the licensed technology as the licensor continues to research the subject technology. The licensor may want to enjoy any enhancements to the technology that are developed by the licensee as it practices the invention. This element of the agreement explains how such property will be handle and if additional compensation will be required. Representations and warranties by both parties are common elements. Typically the licensor declares that it has the necessary rights to grant the license and the licensee declares that it is willing and able to accept the license. It has been held in court that there is no implied warranty that the licensed patents are valid. There is no implied warranty that products made under the licensed patents will not infringe the patents of a third party. Other representations and warranties should establish that the licensor does not have any conflicting agreements. Third-party infringement lawsuits may be accepted as the responsibility of the licensor. If the licensor agrees to bring such action, it is sometimes wise for the licensor to limit the number of actions that it is required to support at any one time. In return, the licensee should agree to pay royalties while the lawsuit is being fought. an escrow account may be established for the royalties until the lawsuit is decided.

유근피가 고콜레스테롤식이를 급여한 흰쥐의 지질대사에 미치는 영향

이미정,하진옥,이재준,이명렬 朝鮮大學校 附設 醫學硏究所 2009 The Medical Journal of Chosun University Vol.34 No.1

연구배경: 유근피는 기능성식품의 신소재로 개발하기 위해서 체계적인 식품학적 연구 및 생리활성효능의 검증이 요구된다. 본 연구에서는 유근피 에탄올 추출물(UDEE)이 고콜레스테롤식이를 급여한 흰쥐의 지방대사 개선효과에 미치는 영향을 구명하고자 혈청 및 간 중의 지질 조성 변화를 검토하였다. 방법: 5주령의 Sprague Dawley계 웅성 흰쥐에게 1% 콜레스테롤과 0.25% sodium cholate를 함유한 고콜레스테롤식이를 조제하여 6주간 급여하였다. 실험군은 정상식이군(NOR), 고콜레스테롤식이군(대조군, CON), 정상식이와 유근피 에탄올 추출물 저용량 투여군(UD1), 정상식이와 유근피 에탄올 추출물 고용량 투여군(UD2), 고콜레스테롤식이와 유근피 에탄올 추출물 저용량 병합 투여군(UDC1) 및 고콜레스테롤식이와 유근피 에탄올 추출물 고용량 병합 투여군(UDC2)의 6군으로 나누어 실시하였다. 유근피 에탄올 추출물은 매일 같은 시각에 경구 투여한 후 흰쥐의 혈액과 간장 내의 지질 조성을 관찰하였다. 결과: 체중증가율과 간 무게는 CON군이 NOR군에 비하여 높게 나타났으나, 고콜레스테롤식이와 유근피 추출물을 병합 투여한 UDC1군과 UDC2군에서 점차 감소하는 경향을 보였다. 혈청 중 ALT, AST 및 ALP 활성은 CON군에서 유의적으로 증가하였고, UDEE 투여로 농도 의존적으로 감소하였다. UDEE 투여군에서는 CON군에 비하여 HDL-콜레스테롤/총콜레스테롤, HDL-콜레스테롤 및 인지질 함량은 증가하였으나 중성지질, 총콜레스테롤, 유리콜레스테롤 및 LDL-콜레스테롤 함량은 감소하였다. 중성지질, 인지질, LDL-콜레스테롤, HDL-콜레스테롤 및 유리콜레스테롤 함량은 정상식이를 급여한 군들 간에는 유의차가 없었다. 또한, 간 중 중성지질과 총콜레스테롤 함량도 UDEE 투여군이 CON군에 비하여 낮았다. 결론: 유근피 에탄올 추출물은 혈청 및 간의 콜레스테롤 함량을 저하시켜 고콜레스테롤혈증 예방과 치료에 효과적일 것으로 판단되어진다. Background and Objectives: This study was performed to investigate the effect of ethanol extract of Ulmus davidiana var. japonica Nakai(UDEE) on serum and liver lipid metabolism in rats fed high cholesterol diet. Methods and Materials: Male Sprague-Dawley rats were administered 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia. We divided into six groups; normal diet group(NOR), high cholesterol diet group(CON), normal diet and UDEE 200 mg/kg administered group(UD1), normal diet and UDEE 400 mg/kg administered group(UD2), high cholesterol diet and UDEE 200 mg/kg administered group(UDC1), and high cholesterol diet and UDEE 400 mg/kg administered group(UDC2). Results: The growth rate and liver weight of the CON group was higher than the NOR, whereas the administered UDEE groups were gradually decreased. There was a significant increase in the activities of serum ALT, AST and ALP in CON group. The administration of UDEE decreased serum ALT, AST and ALP activities in dose dependently manners. UDEE administered groups were increased HDL-C/T-C, HDL-cholesterol and phospholipid levels, and decreased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels as compared with CON group. There were no differences in the levels of serum triglyceride, phospholipid, LDL-cholesterol, HDL-cholesterol and free cholesterol between normal diet groups. The hepatic levels of total cholesterol and triglyceride were also lower in UDEE administered groups than in CON group. Conclusion: These results suggest that UDEE exerts hypocholesterolemic effect by reducing serum and liver cholesterol contents.

이행성 협심증 환자에서 운동부하 심전도 검사

이정우,박형서,박용규,노상필,이유선,정승현,김보영,이재환,최시완,정진옥,성인환 충남대학교 의과대학 의학연구소 2003 충남의대잡지 Vol.30 No.1

목적 : 관상동맥의 경련에 의한 이형성 협심증환자에 있어서 운동부하 심전도 검사의 결과는 매우 다양하다. 이에 저자들은 충남대학교병원 순환기내과에서 관상동맥조영술상 이형성 협심증으로 확진된 환자를 대상으로 운동부하 심전도 검사를 시행하여 이에 대한 결과를 연구하였다. 방법 : 1995년 1월부터 2002년 3월까지 흉통을 주소로 충남대학교병원 순환기 내과에 입원하여 관상동맥조영술을 시행하여 관상동맥의 내경이 50% 미만의 협착이 있고, 에르고노빈(ergonovine) 유발검사도 이형성 협심증으로 진단을 받은 233명중 운동부하 심전도 검사를 시행 받은 183명의 환자를 연구 대상으로 하였다. 운동부하 심전도 검사 결과의 판독시 발생할 수 있는 오류를 줄이기 위해서 운동부하 심전도 검사를 시행하기전 심전도상 ST분절의 상승(5예)이나 하강(8예)이 있는 경우 EH한 T파의 역위(19예)가 있는 32명의 환자를 제외한 총 151명의 환자를 대상으로 하였다. 운동부하는 Marquette사의 case 15 답차를 이용하였고, Bruce protocol에 따라 증상이 나타날 때까지 최대로 실시하였으며 각 stage 및 운동후의 혈압을 측정하고 12 유도 심전도를 기록하였다. 결과 : 1) 임상적 특성 - 내원시 임상 상은 안정형 협심증이 39예(25.8%), 불안정형 협심증이 103예(68.2%), 심근경색증이 9예(6.0%)이었다. 운동부하 심전도 검사 결과 양성 군과 음성군간에 있어서 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연 여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도, 연축의 수 등을 조사하였는 바 어떠한 인자들도 유의한 차이를 발견할 수 없었다. 2) 운동부하 심전도 검사 - 운동부하 심전도 검사를 시행 받은 151명의 환자중 음성인 경우는 134예(88.8%)이었고, 양성인 경우는 17예(11.2%)이었다. 양성 소견을 보인 환자들중 ST 분절의 상승이 4예(2.6%), ST 분절의 하강이 13예(8.6%)이었다. 3) 관상동맥조영술 - 관상동맥조영술상에서 혈관 경력 위치는 우관상동맥이 70예(46.1%), 좌전하동맥이 44예(28.9%), 좌회선동맥이 17예(11.2%)의 순으로 나타났다. 운동부하 심전도 검사상 ST 분절의 상승이 있었던 예중 Ⅱ, Ⅲ, aVF에서 ST 분절의 상승이 있었던 1예는 관상 동맥조영술상 우관상동맥에서 경련이 발생하였고, V2-V4에서 ST 분절의 상승이 있었던 2예중 관상동맥조영술상에도 좌전하행동맥에서 경련이 나타난 예는 1예이었으며 다른 1예는 좌회선동맥에서 경련이 나타났고, V5-V6에서 ST 분절의 상승이 있었던 1예는 관상동맥조영술상에도 좌회선동맥에서 경련이 나타났다. 운동부하 심전도 검사상 V5 또는 V6에서 ST 분절의 하강이 있엇던 13예중 6예(46.1%)는 관상동맥조영술상 우관상동맥에서 경련이 발생하였고, 3예(23.1%)는 좌전하행동맥에서, 1예(7.7%)는 좌회선동맥에서, 나머지 3예(23.1%)는 2개의 혈관이나 기타 분지에서 경련이 발생하였다. 결론 : 1) 이형성 협심증 환자는 운동부하 심전도 검사에서 11.2%의 양성소견을 보였다. 이중 ST 분절의 상승은 2.6%이었고, ST 분절의 하강은 8.6%이었다. 2) 이형성 환자중 운동부하 심전도 검사를 실시하여 음성을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 3) 이형성 협심증 환자중 운동부하 심전도 검사를 실시하여 ST 분절의 상승을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 4) 운동부하 심전도 검사 결과에 대한 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도 등 어떠한 인자들도 3그룹(ST 분절의 상승, ST 분절의 하강, 음성)간에 유의한 차이를 발견할 수 없었다. 5) ST 분절의 상승 부위와 관상동맥조영술상 관상동맥의 연축이 일어나는 혈관과의 상관관계는 매우 높았다. No reports in the literature describe the results of exercise testings in a large number of patients with pure variant angina(coronary stenosis <50%) in Korea. In this report, We present the results of treadmil exercise testing in 151 patients with variant angina. 151 patients with angiographically proven coronary artery spasm underwent a treadmil exercise test. The clinical characteristics of variant angina patients classified according to ST-segment response to exercise were analyzed. Of 151 patients underwent a treadmil exercise test, negative result was seen in 134 patients(88.8%) and positive result was in 17 patients(11.2%). Of 17 patients saw positive result, exercise-induced ST segment elevation was present in 4 patients(2.6%) and ST segment depression was seen in 13 patients(8.6%). There was not a significant relationship between the ST segment response to exercise and the clinical variables(diabetes, hypertension, obesity, total cholesterol, current smoking, effort angina, clinical diagnosis, and degree of stenosis) assessed. Of 4 patients with ST segment elevation in treadmil exercise test, 1 patient with ST segment elevation in Ⅰ,Ⅲ,aVF had spasm in right coronary artery(100%) on coronary angiography, of 2 patients in V2-V4 had spasm in left anterior descending coronary artery in 1 patient(50%) and 1 patient in V5-V6 had spasm in left circumflex artery(100%). Positive treadmil exercise test was present in 11.2% of variant angina patient. If we have negative treadmil exercise result in patients with clinical manifestation of unstable angina at admission, we may have a suspicion of variant angina rather than multi-vessel disease. If we have exercise-induced ST segment elevation in patients with clinical manifestation of unstable angina at admission, we have a suspicion of variant angina rather than multi-vessel disease. Our result suggests that the correlation between the site of the ST segment elevation and the artery involved is quite good.
