C.Monteverdi의 Madrigal의 分析 硏究

李俊源 서원대학교 예술문화연구소 1998 예술문화논총 Vol.7 No.-

C.Monteverdi's eight-volumn madrigal collections are the central part of his work which illustrates the new type of music he creates on the basis of the Monody style he borrow from the music of the later Renaisance period. In the madrigals, he attempts to boldly cast off the formals of Cromatic madrigals, and the conjunction of the verses and music via Counterpoint and Monody techniques constitutes the foundation of his aesthetics. His music in the madrigals is characterized by the phonic schemes of the melodies, simplex musical forms, romantic techniques of expression, sequences of harmony in a chromatic scale, decorative phonec schemes of instruments, parallel three-degree sequence, jumping intervals, sequences, alternative use of major and monor scales, and bold non-harmonic tones and Pedal point. Through these techniques, he welds the poems and music tightly. By employing widely all the techniques necessary to rendering poitic images in sounds, he not only opens a new techniques necessary to rendering poitic images in sounds, he not only opens a new chapter of Renaisance music: by using Basso continuo and inventing performance techniques like pizzicato, he also creates new acoustic effects. His madrigans in his later period make a critical contribution to the opening of the baroque music like oratorios and operas.

C.Gesualdo da Venosa의 Madrigal의 分析硏究

李俊源 서원대학교 예술문화연구소 1999 예술문화논총 Vol.8 No.-

Although he was born in a distinguished family and was in the position of a leader of the high class society, Gesualdo had to lead a life full of mental distress and pain due to his tragic marriage life. His miserable life exerted more influences on his works than with any other composers; he couldn't express his musical desires with traditional techniques only. This necessarily demanded new modes of expression; he expressed the inner world of human beings through protruding notes in the high key, grand and unpredictably piquant cacophonies, chromatic development of harmony, and so on. His experimental attempts not precluding traditional techniques raised the music of his own age onto a new level and placed him in the seat of the musician who perfected the Renaissance music. Although not large in number of works, his restrained and refined music influenced many composers in the 20th century including Stravinsky (Pietroburt 1882-New York 1971).

Background: Elevation of blood pressure (BP) and the increasing incidence of hypertension have been known to be associatedwith time course, especially age. But there is still lack of evidence of BP change and the association with biochemical markersor markers for subclinical organ damage in Korean general population. Thus, the purpose of this study is to investigate BPchange and the related factors in established Korean mid-aged rural cohort. Methods: This study was performed by usingdata from ARIRANG cohort (Atherosclerosis Risk of a Rural Area Korean General Population) in Gangwon rural area. Data werecollected from baseline survey (Nov 2005-Jan 2008) and follow-up survey (Apr 2008-Jan 2011). Among 5,515 participants,1,863 were analyzed after excluding individuals with hypertension, diabetes mellitus, cerebral infarction, myocardialinfarction, missing data for BP, and newly-developed hypertension. Results: Mean age was 53.4 ± 8.2 years and men were718 (38.5%). Mean follow-up period was 2.4 ± 0.9 years. Baseline systolic and diastolic BP were 123.6 ± 15.7 mm Hg and79.2 ± 10.8 mm Hg. Systolic BP changes were -10.9 ± 15.3 mm Hg and diastolic BP changes were -7.7 ± 11.8 mm Hg. Inlogistic regression analysis, predictors for elevation of systolic BP on follow-up were start regular exercise (odds ratio [OR],0.765; 95% confidence interval [CI], 0.604 to 0.968; p=0.0257) and fasting glucose (OR, 0.984; 95% CI, 0.972 to 0.996;p=0.0102) and homeostasis assessment-insulin resistance (OR, 0.82; 95% CI, 0.707 to 0.952; p = 0.0086). Conclusions:Follow-up systolic and diastolic BP were significantly decreased when compared to baseline BP in mid-aged Korean ruralcohort population. Long-term follow-up is needed to discriminate the periodic change of BP and the associated factors. 연구배경: 시간의 흐름, 특히 연령의 증가에 따라 혈압이 상승하고 고혈압이 발생하는 것으로 알려져 있다. 하지만 한국인을 대상으로 한 일반 인구집단에서, 시간에따른 혈압의 변화 및 이와 연관된 혈액학적 지표, 무증상장기손상 지표들과의 연관성에 대한 자료는 부족한 실정이다. 따라서 본 연구에서는 코호트 집단에서 혈압의 변화를 분석하고 이와 연관된 요인들을 알아보고자 하였다. 방법: 이 연구는 원주, 평창 농촌지역의 인구집단을 대상으로 한 ARIRANG 코호트(Atherosclerosis Risk of a Rural Area Korean General Population) 자료를 이용하여분석하였다. 2005년 11월부터 2008년 1월까지 기초조사를실시하였고, 2008년 4월부터 2011년 1월까지 재조사를시행받은 대상자들 중 고혈압, 당뇨, 고지혈증, 뇌경색, 심근경색의 과거력이 있거나, 혈압을 측정하지 않은 자, 항고혈압 약물치료에 대한 정보가 부족한 새로 진단된 고혈압환자를 제외한 1,863명을 대상으로 분석을 시행하였다. 결과: 평균 나이는 53.4 ± 8.2세, 남자가 718명(38.5%) 를 차지했다. 평균 추적관찰기간은 2.4 ± 0.9년이었다. 전체집단의 기초조사 수축기혈압은 123.6 ± 15.7 mm Hg이었고, 이완기혈압은 79.2 ± 10.8 mm Hg였다. 재조사 수축기혈압은 전체집단에서 -10.9 ± 15.3 mm Hg, 남자-12.0 ± 15.6 mm Hg, 여자 -10.2 ± 15.1 mm Hg(남자 대여자 p = 0.0141)로 감소했다. 이완기혈압도 -7.7 ± 11.8 mm Hg(전체집단), -8.9 ± 11.8 mm Hg(남자), -6.9 ± 11.6 mm Hg(여자) (남자 대 여자 p = 0.0003)으로 감소했다. 다중 로지스틱회귀분석에서 혈압의 변화(상승)과 연관된의미 있는 예측인자는 운동 시작(odds ratio [OR], 0.765; 95% confidence interval [CI], 0.604 to 0.968; p = 0.0257), 공복혈당(OR, 0.984; 95% CI, 0.972 to 0.996; p = 0.0102), HOMA-IR (OR, 0.820; 95% CI, 0.707 to 0.952; p = 0.0086)이었다. 결론: 중년의 원주 평창 농촌 코호트 집단에서 혈압의변화를 관찰했을 때, 재조사 혈압이 처음보다 유의한 감소를 보였다. 장기적인 추적관찰을 통한 혈압의 변화 및이와 연관된 요인들에 대한 분석이 필요하다.

Background & Objective: Perfusion imaging (PI) of magnetic resonance imaging (MRI) uses the signal loss that occurs during dynamic tracking of the first pass of intravenous paramagnetic contrast agent. Then different hemodynamic measurements can be calculated and displayed as perfusion maps. We evaluated clinical usefulness of PI in acute ischemic stroke. Methods: Fifteen patients with clinical diagnosis of acute cerebral infarction were imaged with PI, DWI, and magnetic resonance angiogram (MRA) including FLAIR within 24 hours after onset. Comparisons were made between infarct volumes measured by PI using the parameters including relative mean transit time (rMTT) map, relative cerebral blood volume (rCBV) map, and relative cerebral blood flow (rCBF) map. Results: Two patterns were found: 1) rMTT map in PI lesion larger than the rCBV map lesion(n=7/15), and 2) rMTT map in PI lesion of the same size or smaller than rCBV map lesion(n=8/15). The former pattern was shown in cases with severe stenosis or occlusion of the major cerebral artery(MCA, PCA, or ICA) on MRA. The majority of latter pattern was lacunes(n=6/8). Also, we found presence of infarction cores surrounded by hypoperfused areas in rMTT map in acute large-arterial territorial infarction. Conclusions: Perfusion MRIs may be useful in differentiating large-arterial territorial infarction from lacunes.

R.Wagner의 Reingold에서 Theme의 사용에 관하여

李俊源 서원대학교 예술문화연구소 1996 예술문화논총 Vol.5 No.-

To attain his ideal of composite art, Wagner thought that poetic, musical, and dramatic ingredients should be closely correlated with one another, and accordingly used Leitmotiv and Melody Infinite. In this paper, we study the phraselogy of Wagner's operas by examining how the motives of the Ring and of Walhall are correlated in the prelude Das Reingiold of his opera The Ring of Nibelungen. The motive of Walhall is derived from that of the Ring. The two motives share the characteristic of being a means in governing the whole world: the Ring is pictured as the symbol of money and power, and Walhall, as the symbol of immortality. Wagner attempts a musical contrast in characterizing the two different, but correlated, motives by means of the melodies and of the rhythms of the music, on the one hand, and by means of the wood wind and of the brass on the other. Closely correlated since their birth, the two Leitmotivs function to unite the acts of the drama together and attempt to harmonize the drama itself and the music by explicating and implicating the present, past, and future dramatic situations. This musical phraselogy of Wagner has strong influences on the late works by G.Verdi(18j13-1901) and opera composers of the late period of romanticism.

기술력 평가항목을 이용한 고활동성 중소기업 판별

이준원 기술경영경제학회 2020 Journal of Technology Innovation Vol.28 No.1

본 연구는 기술금융에 사용되는 ‘미래 진보성’ 중심의 기술력 평가모형을 이용 하여 기업의 고활동성 여부에 대한 사전적(Ex-ante) 판별력 검증을 목적으로 한다. 분석 대 상기업을 업종(제조업군/非제조업군)과 업력(창업기업군/非창업기업군)으로 구분한 후 해당 군집의 평균 총자산회전율 2배 이상을 달성한 기업을 고활동성 중소기업으로 정의하였다. 의 사결정나무 모형 중 하나인 C5.0 기법을 적용하여 판별모형을 작성한 결과 모든 업종과 업력 에서 99% 이상의 분류정확도를 보였으며, 모형의 판별력이 안정적임을 확인하였다. 분석 결 과 경영진 전문성, 자본참여도, 자금조달능력 항목은 업종⋅업력과 무관하게 고활동성 중소 기업 여부를 결정하는 중요변수로 확인되었으며, 제조업군에서는 기술경영능력과 기술수명 주기 또한 고활동성 중소기업 여부를 결정하는 평가항목임이 확인되었다. 이를 통해 기술력 평가항목을 이용하여 고활동성 중소기업 여부에 대한 사전적 판별 및 정책적 활용에 대한 가 능성을 일정부분 확인할 수 있었다. This study was started to verify the preliminary(Ex-ante) discrimination power of the firm's high-activity using the ‘Forward-looking’ oriented technology appraisal model used in technology financing. The analytical firms are classified into the industry (manufacturing / non-manufacturing) and the age of company (initial / non-initial). High-activity SMEs are defined as those that achieve at least twice the average asset turnover ratio of the cluster. As a result of the discriminant model by applying C5.0 method, which is one of decision tree models, classification accuracy is more than 99% in all industries and the age of company, and it is confirmed that the discriminant power of the model is stable. As a result, the management expertise, capital involvement and funding capacity items were identified as a critical variable for the high-activity SMEs. In addition, the technology management capability and technology life cycle were also confirmed to be the items to determine high-activity SMEs in the manufacturing industry. Through this, it was possible to confirm some possibility of prior discrimination and policy utilization of high-activity SMEs by using technology appraisal items.

L.MARENZIO의 MADRIGAL의 分析 硏究

李俊源 서원대학교 예술문화연구소 1997 예술문화논총 Vol.6 No.-

Marenzio was a representative composer of 16th Century, and new chapter by integrating the previous techniques of expression into his various ones and making poetry and music have a closer relationship with a set of new techniques. He depicted with music everything in poems(that is the objects, motions psychological changes, and so), as if he drew a painting: particularly by means of contrast between homophony and polyphony, altermative male and chorus, contrast in tone colors, declamation, avoidance of cadence, intervals of tones, consecutive advances, syncopation, radical harmonies, and an emphasis of the melody on the high vocal parts. His such techniques exerted a great influence on the technical advances of the 16th Century and further the development of Italian vocal music literature.
