포스트모더니즘을 통한 새로운 예술론 연구

이강일 통일사상학회 2017 통일사상연구 Vol.12 No.-

모더니즘은 가치중립이고 합리주의와 경험주의에 바탕을 둔 계몽사상을 계승 한 서구 근대 이성중심의 철학이다. 포스트모더니즘은 인간을 중심한 다양한 가 치수용이 특징이며 서구 이성중심의 합리적이고 과학적인 방법에 문제점을 지적 하고 해체하고자 하며 감성영역에 기대를 건다. 그러나 포스트모더니즘의 많은 철학사적 의의에도 자체가 만들어 놓은 또 다른 문제점의 한계에 봉착하고 있다. 이 논문에서 극복논리는 보편과 개별의 통합, 주 류와 비주류의 통합, 이성과 감성의 통합에 의해서 이루어짐을 설명하고 있다. 특 히 포스트모더니즘의 예술론은 비동일성, 무목적성, 숭고미학, 감각의 논리 등은 모두 감성언어에 의존하고 있음을 알 수 있다. 이러한 감성언어의 바탕에는 예술 을 통해서 새로운 탈출구를 모색하고자 하는 그들의 의도가 숨겨져 있다. 새로운 예술론은 포스트모더니즘이 간과하고 있는 목적성(방향성)에 바탕을 두어야 한다. 목적성이 없는 미학은 불가능하며, 이것은 예술철학인 미학을 바탕 으로 한 창조행위를 진정한 예술이라고 하기 때문이다. 새로운 예술론은 올바른 창조원리와 구조를 바탕으로 성립하기 때문에 예술은 포스트모더니즘이 찾고자 한 기존의 이성중심의 사고를 해체한 결과에서 출발하여 예술의 구조를 통해서 새로운 패러다임을 찾는 연구이다. Modernism is the western modern reason-centered philosophy which adopted value-neutral Enlightenment based on rationalism and empiricism. But the main character of postmodernism is to accept human- centered various values, in attempt to criticize and deconstruct problems with western reason-centered rational and scientific methods, having expectations for the emotional domains. Postmodernism promoted methodology about overcoming reason- centered limits after the 21st century. The academic school continued to have expectations on emotion. In this regard, the purpose of this research study is to consider theories of art through purposes and values of emotion that postmodernism attempted to pursue, placing the significance on seeking new paradigms through theories of art that has inseparable relations with emotional structures. The character of postmodernism means ex-modernism. Ex-modernism was obliged to create a novel massive-discourse based on the possibility of emotion that had relatively been disregarded, after reason-centered massive-discourse came to an end that had, so far, been dealt with. However, it is not easy to create a new massive-discourse because this is possible only when there is a change in general paradigms. Yet, it is considered that postmodernism can overcome its limits through the integration with universal and individual, mainstream and non-mainstream, reason and emotion. And it is identified that all theories of art accommodating nonidentity, purposeless-purposiveness, sublime aesthetics, emotional logic pursued by postmodernism depend on emotional languages. Thus in emotional languages lies the intention to find new ways through arts. The new artistic theory should be based on the objectivity(directionality) that postmodernism overlooks, because aesthetics without purposiveness is impossible, and creation act built on aesthetics as an art philosophy is worth to be called true art. Given that new theories of art are applied on the basis of right principles and structures of creation, this study is to seek new paradigms through art structures, starting from the outcome of the constructivism of the existing reason-centered paradigms supported by postmodernism. In this context, this research study means to provide the new possibility of art theories through the integration of multi-discourses in the process of constructing the existing reason-centered paradigms of multi-discourse to establish the accurate concepts of art. To do it, this study is going to present the structures that reason and emotion intend to integrate, asserting that post-constructivism pursing new ideas must find a clue through theories. of art. The nature of art lies in creation, and art, fundamentally, promotes aesthetics. It can, thus, be found that, since aesthetics promotes purposive directions and purposes within the emotional domains, art exists by constructing the outcomes of the established paradigms through new art structures, where postmodernism intended to pursue.

Ultrasonic Technique for Measuring the Thickness of Scale on the Inner Surfaces of Pipes

이강일 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.56 No.2

At the present time, there are no known commercialized nondestructive techniques for measuring or detecting the scale on the inner surfaces of pipes in situ. The present study aims to develop an ultrasonic technique for measuring the thickness of scale on the inner surfaces of pipes in situ. All experiments were carried out under laboratory conditions by using three pipe samples with scale (HNO3). The pipe samples were made of polypropylene (PP), polyvinyl chloride (PVC), and steel,respectively. The ultrasonic technique developed in the present study was successfully applied to determine the scale thicknesses of the PP and the PVC pipes whereas it was not applicable to the steel pipe. It is expected that a predetermined graph for a particular type of scale, relating the scale thickness to the time of flight of a pulse within the scale, can be used in further testing, thereby eliminating the need for future destructive inspections.

Dependencies of Acoustic Properties on the Frequency, Porosity, and Grain Size in Water-Saturated Sandy Sediment from 150 to 350 kHz: Application of the Grain-Shearing Model

이강일 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.56 No.1

In the present study, the grain-shearing (GS) model for wave propagation in a saturated, unconsolidated,granular material was applied to predict the dependencies of the acoustic properties, such as the phase velocity and the attenuation, of the compressional wave on the frequency, porosity,and grain size in water-saturated sandy sediment over the frequency range from 150 to 350 kHz. The GS model predicted a slightly positive velocity dispersion and a near-linear relationship of the attenuation with the frequency, following well the trends of the data acquired from water-saturated sandy sediment with a porosity of 0.408 and a mean grain diameter of 425 µm. The predictions for the relationships of the acoustic properties with the porosity and the grain size also showed good agreement with the measurements. These results suggest that the GS model may be usefully employed as a practical tool for estimating the acoustic and the physical properties of a sediment.

Frequency Dependencies of Acoustic Properties in Water-Saturated Sandy Sediment from 0.5 to 1.0 MHz: Application of the Modified Biot-Attenborough Model

이강일 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.6

In the present study, the modified Biot-Attenborough (MBA) model for acoustic wave propagation in fluid-saturated porous media was applied to predict the frequency dependencies of the phase velocity and the attenuation coefficient for the fast wave in water-saturated sandy sediment. Measurements of the phase velocity and the attenuation coefficient were performed over a frequency range from 0.5 to 1.0 MHz for water-saturated sandy sediment with a mean grain diameter of 400 μm and a porosity of 40 %. The experimental results revealed that the phase velocity exhibited a slightly negative dispersion linearly with the frequency and that the attenuation coefficient increased almost linearly with the frequency. The measurements were in good agreement with the model predictions over the frequency range covered here. Further studies will be required in frequency ranges not covered by existing data in order to establish completely the adequacy of the MBA model.

Relationships of Bone Density with Quantitative Ultrasound Parameter in Bovine Cancellous Bone

이강일 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.1

The present study aims to investigate the relationships of bone density with quantitative ultrasound (QUS) parameters measured in transmission and backscatter modes in bovine cancellous bone. The speed of sound (SOS), the normalized broadband ultrasound attenuation (nBUA), the broadband ultrasound backscatter (BUB) and the integrated reflection coefficient (IRe) were measured for 35 specimens obtained from proximal ends of seven bovine tibiae. The highest correlation coefficient was observed for SOS (r = 0.75, p < 0.001). Similarly, nBUA was significantly correlated with density (r = 0.71, p < 0.001). In contrast, BUB and IRe were less correlated with density than transmission QUS parameters, but still significantly (r = 0.63 and 0.65, respectively, all p < 0.01). A multiple regression analysis was used to find optimal models for the prediction of apparent bone density by using linear combinations of SOS, nBUA, BUB and IRe, with density as an independent variable and 2,3 and 4 QUS parameters as dependent variables (r = 0.77 - 0.88, all p < 0.001). The results suggest that the analysis of multiple QUS parameters can contribute to improving the efficacy of QUS procedures in the diagnosis of osteoporosis beyond the established value of SOS and nBUA.

전자빔 증착법으로 성장한 NiO 박막의 전기적, 전자구조 및 광학적 특성

이강일,유스라마덴니,강희재,박남석 한국물리학회 2014 새물리 Vol.64 No.5

NiO thin films having 50 nm thickness were grown by using e-beam evaporation at room temperature, after which in-situ post-annealing was carried out at temperatures of 100℃, 200℃ and 300℃ for 30 minutes. The electrical, electronic structure and optical properties of the NiO thin films were obtained via Hall measurements, X-ray photoelectron spectroscopy (XPS), reflection electron energy loss spectroscopy (REELS), and UV spectrometer. The electrical properties of the NiO thin films grown at room temperature and post-annealed at 100℃ showed p-type semiconducting properties, and the average transmittance in the visible region was more than 70%. These results showed that NiO thin films should have applications as p-type transparent thin-film semiconductors. To the contrary, NiO thin films post-annealed at temperatures over 200℃ showed n-type semiconductor properties, and the average transmittance in the visible region was drastically decreased due to the formation of Ni-metal bonding. 전자빔증착법 (electron-beam evaporation)을 이용하여 유리 기판에 50 nm의 NiO 박막을 성장시킨 후 진공용기 내에서 100℃, 200℃, 300℃ 온도로 후 열처리를 하였으며, 박막의 전기적, 전자구조 및 광학적 특성을 홀 측정, 광전자 분광법, 반사 전자 에너지 손실 분광법 및 UV-spectrometer 실험 통하여 연구를 하였다. 실온 및 100℃로 후 열처리를 한 박막의 경우 p형 반도체 특성의 전기적 특성을 나타내었으며, 투과도 또한 가시광 영역에서 70%이상의 투과율을 나타내었으며, 이는 p형 투명전자소자로의 응용이 가능하다는 것을 보여주었다. 반면 200℃, 300℃ 온도로 후 열처리 한 박막의 경우, 표면에 Ni 금속 결합의 생성으로 n형 반도체 특성으로 변화하였으며, 투과율 또한 급격히 감소하는 것으로 나타내었다.

Dependences of the Backscatter Coefficient on the Frequency, the Bone Volume Fraction, and the Trabecular Thickness in Bovine Femoral Trabecular Bone In V itro

이강일 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.63 No.5

The present study aims to provide insight into the dependences of the backscatter coefficient onthe frequency, the bone volume fraction (BV/TV), and the trabecular thickness (Tb.Th) in bovinefemoral trabecular bone in vitro. The frequency-dependent backscatter coefficient was measuredin 20 bovine femoral trabecular bone samples over a frequency range from 0.2 to 0.7 MHz. Thebackscatter coefficient measured at 0.5 MHz exhibited significant positive correlations with theBV/TV (r = 0.76) and the Tb.Th (r = 0.77). The power-law fits to the measurements showedthat the backscatter coefficient was empirically proportional to the frequency, the BV/TV, and theTb.Th with exponents of n = 2.9, 1.3, and 1.8, respectively. The present study also used a scatteringmodel, in which the scattering coefficient was proportional to the product of the mean velocityfluctuation and the correlation function integrated over the volume, to predict the measurements. The measurements were found to largely fall within the range of the predictions obtained from thescattering model.
