삼탄(三灘) 이승소(李承召) 제화시(題畵詩)의 형상화(形象化) 양상 -화의(畵意)의 표현방법을 중심으로-

이정규 ( Jeong Gyu Lee ) 충남대학교 인문과학연구소 2012 인문학연구 Vol.39 No.1

이 논문은 15세기 관료문인의 일인으로 문명을 떨친 삼탄 이승소의 시세계를 탐색하는 일환으로 그의 제화시의 형상화 양상을 살펴본 것이다. 15세기는 제화시 창작이 가장 성행한 시기이며 삼탄의 제화시 또한 수적으로 상당히 많다. 또한 인물화에서 산수화에 대한 관심으로 서화에 대한 애호의 경향이 바뀌어가고 있으며, 그림의 가상성을 인식하고 이를 바라보는 시인의 내면에 관심을 돌리고 시인의 모습을 주제화하는 모습을 보이고 있다. 삼탄은 서화를 대할 때 그것의 眞·假에 함몰되지 않고 또 그것에 전념[留意]하는 것이 아니라 자유로이 뜻을 붙이는[寓意] 행위로 이해하며, 서화를 마음으로 보아 그것의 본질을 꿰뚫어 보는 태도를 견지하고, 그 안에서 정신적인 즐거움을 찾았던 것으로 보인다. 한 폭을 그림을 대하고 그것을 시로 재산출할 때는 그 대상에 따라 畵意를 유가적 관념이나 상징을 바탕으로 형상화하기도 하였으며 상상을 통해 혹은 자신의 주관적 해석에 따라 화의를 덧붙이기도 하였다. 그 가운데 화면을 묘사하면서도 화의를 주관적으로 재해석하는 제화시들은 삼탄의 개성이 더욱 드러나 있다. The Aspect of Configuration in the Titled Paintings by Yi Seung-so with the Pen Name of Samtan Lee, Jeong-gyu This thesis examines the aspect of configuration in the titled paintings by Yi Seung-so with the pen name of Samtan to explore the poetic world of the 15th-century courtier and man of letters. The period abounded more in titled paintings than in any other time period, and the poet produced a good number of them. The era`s preference in paintings was shifting from portraits to landscape paintings, while it recognized the virtual reality of a picture and gave attention to the interior topography of the poet observing it. It seems that as he faced a painting, Samtan wasn`t absorbed in its truth or falsehood. He did not focus on it(留意) but construed it as an allegorical act of freely attaching meanings (寓意). The poet appeared to maintain a stance of looking at a painting work with his heart to perceive its essence, while descrying spiritual joy in there. When he was faced with a piece of painting to reconfigure it as a poem, the poet configured the meaning of the painting based on the Confucian ideas or symbols, or added a meaning to the work through imagination or in his subjective interpretation. Of all his painting works, those applying subjective interpretation to their meaning demonstrate Samtan`s personality more distinctively.

이유선,정진옥,박용규,박형서,노상필,정승현,김정희,이재환,최시완,성인환 충남대학교 의학연구소 2003 충남의대잡지 Vol.30 No.2

급성 심근염환자에서 발행한 완전 방실차단을 영구 심장박동 조율기로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Myocarditis, an inflammatory process involving the myocardal wall, may be caused by most infectious agents. Irrespective of its etiology, it presents commonly with evidence of heart failure, hypotension, and various electrocardiographic abnormalities. Patient with myocarditis may be asymptomatic or may have a rapidly progressive fatal disease. Medical management of patients with myocarditis includes specific therapy for underlying infection and control of the complication of myocarditis such as congestive heart failure and arrhythmia. Recently we had experienced myocarditis with complete atrioventricular block in 37-year-old man. Although he had shown complete recovery of heart failure, he had shown complete atrioventricular block, so we inserted permanent pacemaker. We report it with review of the literature.

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.

The purpose of this study is to investigate the correlation between the growth conditions of the crops and the environment of the greenhouse according to the variation of temperature inside the greenhouse. The environment sensor (i.e. temperature and humidity sensor) which were installed in the greenhouse were collected as environmental factor. The growth index of strawberry were measured to fruit length, fruit diameter, fruit weight, sugar content and yield according to the average temperature and humidity. The correlation between the environmental factors in the greenhouse and the growth index of strawberry was investigated by simple linear regression. The production of strawberry showed a slight difference in each location, but the production of strawberry was increased in the area close to the heater.

목적: 인플루엔자는 매년 겨울 전 세계적인 유행을 일으키는 급성 호흡기 질환으로 높은 이환률과 사망율을 보인다. 국내에서도 1996-1997년 겨울철에 다수의 보고가 있었으나 아직 체계적인 감시가 이루어지고 있지 못하다. 저자들은 이 기간 동안 인플루엔자 바이러스 감염의 역학적 특성과 임상상을 연구하여 인플루엔자 감시의 기초 자료를 제공하고자 하였다. 방법: 1996년 10월부터 1997년 4월까지 삼성서울병원 임상병리과에 인플루엔자 바이러스 배양 검사가 의뢰된 모든 검체를 대상으로 인플루엔자 바이러스의 분리율과 유행 양상, 그리고 환자들의 임상상을 후향적으로 조사, 분석하였다. 결과: 총 461명의 환자로부터 525례의 검체가 의뢰되어 총 98명의 환자로부터 인플루엔자 바이러스가 분리되었다. 인플루엔자 A형은 54명의 소아 환자와 4명의 소아 환자로부터 분리되었다. 아형과 항원 특성 검사를 시행한 31례의 인플루엔자 A형 중 한 예에서 A/Wuhan/359/95 유사주로 확인되었고 12례의 인플루엔자 B형 중 5례에서 B/Guangdong/8/97 유사주로 확인되었다. 인플루엔자의 유행 양상은 3월과 4월 중순, 두 번의 인플루엔자 최고 분리 시점이 관찰되었고, 가장 많은 불리 빈도를 보인 연령층은 인플루엔자 A형의 경우 1세 미만이었고 인플루엔자 B형의 경우 3-5세였으며 폐렴이 가장 흔한 호흡기 질환이었다. 결론: 저자들은 3차 의료기관에서 분리된 인플루엔자 바이러스에 대한 역학적, 임상적 특성을 연구하였다. 지역사회에 대한 광범위한 연구가 아니므로 국내의 전반적 상황과는 차이가 있을 것으로 생각되지만 우리나라에서도 인플루엔자 바이러스의 이환률이 낮지 않을 것으로 생각되며, 보다 조직적이고 전국적인 인플루엔자 감시가 이루어져야 할 것으로 사료된다. Background: Although influenza has been a leading cause of global morbidity and mortality, we have few data regarding the epidemioloical and clinical characteristics of influenza activity in korea. Since an outbreak of influenza was recognized during winter of 1996-1997, we analysed the epidemiological and clinical features of influenza activity in the hospital seeting. Methods: All clinical specimens requested for isolation of influenza virus at Samsung Medical Center from October 1996 to April 1997 were included. Mardin-Darby canine kidney (MDCK) cell line was used for virus culture. Isolated viruses were confirmed with immunostain followed by subtyping. The demograpic and clinical characteristics of the patients were reviewed retrospectively. Results: Ninety eight influenza viruses were isolatd from 461 patients (21.3%). Influenza A and B virus were isolated from 58 (54 children and 4 adults) and 40 pediatric patients, respectively. One of 31 influenza A viruses was confirmed as A/Wuhan/359/95-like strain and 5 of 12 influenza B viruses were confiremd as B/Guangdong/8/97-like strains. Two distinctive peaks of influenza activity were recognized and the most common age of patients was less than 1 year for influenza A, and 3 to 5 years for influenza B. Common lower respiratory infections were pneumonia followed by croup, bronchiolitis and laryngitis. Conclusion: We analyzed the epidemiological and clinical features of influenza activity during winter of 1996-1997. Although this study was performed not in the community but in the hospital setting, the morbidity caused by influenza may not be low in Korea. Therefore, nationwide surveillance for influenza activity is warranted.

Defocused CO_2 laser beam irradiation strengthening of 60kgf/㎟ grade steel sheet was investigated to obtain the tensile strength similar to that of fully penetrated one by the focused beam. The melted line width by the defocused beam was 3∼4 times larger compared to that of the focused beam. However, the increase of tensile strength with 1 line irradiation by the defocused beam was similar to that of 2∼3 lines by the focused beam. The increase(37.6%) of bending strength with 1 line by the defocused beam was higher than the increase(12.9%) of tensile strength. Also, the effect of cooling gas to strengthening was observed.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

관상동맥 질환에서 SDF-1α의 농도

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

Atherosclerosis is now viewed as an inflammatory disease of the vascular system. Expression of several chemokines, including monocyte chemoattractant protein(MCP)-1, MCP-4, RANTES(regulated on activation normal T-cell expressed and secreted), and interleukin-8(IL-8) are increased in human atherosclerotic plaques compared with normal vessels. They are involved in the pathogenesis of atherosclerosis and plaque rupture by activating and directing leukocytes into the atherosclerotic lesions. However, some are involved in homeostatic functions such as normal leukocyte traffic and growth regulation. SDF-la is a multi-functional cytokine that is involved in myelogenesis, hematopoiesis, angiogenesis and injured gastric mucosal regeneration in the gastric ulcer patient. SDF-la is recently shown to be highly expressed in atherosclerotic plaques and a potent platelet agonist. At least in high concentrations, SDF-la may mediate antiinflammatory and matrix stabilizing effects in unstable angina. Many studies are going on to know the function of SDF-la in coronary artery diseases. I investigated the difference of the plasma level of SDF-la between control group and coronary artery disease group. Total 75 subjects were enrolled. The diagnosis of coronary artery disease was confirmed in all patients by coronary angiography. Control subjects in this study were confirmed normal by coronary angiography. Clinical profile and risk factors were also reviewed. Control subjects in this study were 27 (M=10, F=17). Plasma for the study was collected before the angiography and centrifuged. SDF-la analysis was performed by ELISA. Plasma level of SDF-la is significantly increased in patients with stable angina(n=20) and unstable angina group(n=28) compared with healthy control group(n=27). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases. In this study, plasma level of SDF-la is increased in patients with stable angina and unstable angina groups compared with healthy control group(P<0.05). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases.

This studies was carried out to investigate the processing possibility of pheasant meat extracts treated with proteases. The crude protein, aminonitrogen, degree of hydrolysis, yield and amino acid composition of pheasant meat extracts when it was treated with proteases at various temperature and reaction time were analyzed. The crude protein contents of pheasant meat extracts processed in 130℃ were more than when it was done in 100℃, but the contents of aminonitrogen were not quite different between two processing temperature. The content of crude protein and aminonitrogen when pheasant meat was hydrolyzed with protease NP and prozyme A. The yields of pheasant meat extracts, when pheasant meat were treated at 100℃ and 130℃, were from 2.24 to 7.10% and from 5.51 to 10.45%, respectively. And the yield of extraction depended on extraction temperature, kinds of enzyme, amount of enzyme, extraction time. The content of aminonitrogen in pheasant meat extracts treated with enzyme was much higher than any other treatments. And it depended on amount of enzyme, extraction time and temperature. The amount of the amino acids in pheasant meat extracts treated by protease NP were eminently higher than by heat at 100℃ or 130℃.

동축선로형 λ/4초크 대역억제필터의 최적화

정봉식,이규한,김진길 東亞大學校 附設 情報通信硏究所 1999 情報通信硏究所論文誌 Vol.7 No.1

In this paper the band-stop filter that rejects the undesired 3th and 5th harmonics generated from high frequench generator is analyzed and optimized. The length of the band-stop filter is setup initially a quarter of a wavelength fo the harmonic, but initial filter structure is unable to cutoff the harmonics because of the fringing effect at the input of the choke. To reduce the mismatch between the cutoff frequency and the harmonics, the length of the choke is optimized by using iterative Levenberg-Marquardt Algorithm.
