현대영화에 나타난 스토리텔링의 구조적 경향을 아피찻퐁의 영화와 구조영화를 통해 비교분석하는 것이 본 연구의 목적이다. 구조적 특징과 관련하여 주요하게 논의된 개념은 반환영성인데 이는 1960,70년대 영미권을 중심으로 활동한 구조/물질주의 영화작가들의 형식적 실험에 영향을 받은 측면이 있다. 하지만 구조/물질주의 영화가 영화형식에 대한 극단적인 실험에 중심을 두고 있었다면 아피찻퐁의 영화는 이를 수용하고 넘어선 포스트모던 영화의 미학으로 확장되었다. 아피찻퐁은 주류적 스토리텔링방식을 거부하거나 무시하기 보다는 환영과 비환영의 개념사이에서 균형을 잡는다. 아피찻퐁은 이를 위해 영상과 음향의 외재성과 내재성을 창의적인 방식으로 활용한다. 현대 영화에서 관찰할 수 있는 주류적 스토리텔링 방식이 아리스토텔레스가 시학에서 언급한 방법론들의 현대적 변용에 기초하여 여전히 환영적 디제시스 창조에 관여하고 있는 반면 아피찻퐁은 구조/물질주의 실험영화의 미학적 성과 위에서 스토리텔링 전략의 새로운 방향을 모색한다.

Recently, as display and semiconductor devices have been miniaturized and highly integrated, there is a demand for optimization of the structural characteristics of the thin film accordingly. The sputtering device has the advantage of stably obtaining a desired thin film depending on the material selected for the target. However, due to the structural characteristics of the sputtering equipment, the structural characteristics of the film may be different depending on the incidence angle of the sputtering target material to the substrate. In this study, the characteristics of the thin film material according to the scattering angle of the target material and the incidence position of the substrate were studied to find the optimization design rule of the sputtering equipment. To this end, a Si thin film of 1 ㎛ or less was deposited on the Si(100) substrate, and then the microstructure, reflectance, surface roughness, and thin film crystallinity of the thin film formed for each substrate location were investigated. As a result of the study, it was found that as the sputter scattering angle increased and the substrate incident angle decreased, the gap energy along with the surface structure of the thin film increased from 1.47 eV to 1.63 eV, gradually changing to a non-conductive tendency.

Stress waves monitored on the surface of structures under various loading conditions can provide useful information on the structural health status. In this paper, stress waves are measured by several sensors when a steel beam is impacted by a ball drop. The sensors used include the piezo-electric film Sensor, the electrical strain gage, and the ultrasonic transducer, and special attention is given to the pieza film sensor. The wavelet transform is used for the time-frequency analysis of dispersive waves propagating in the beam. The velocities of the wave produced in the team due to the lateral impact is found to be frequency-dependent and identified as the flexural wave velocity based on the comparisons with the Timoshenko beam theory. A linear impact site identification method is developed using the flexural wave, and the impact sites of the beam can be accurately estimated by the piezo film sensors. It is found that the piezo film sensor is appropriate for sensing stress waves due to impact and for locating impact sites in the beam.

The fabrication method of plasmonic nanodots on silicon substrate has been developed to improve the efficiency of thin film solar cells. Nanoscale metallic nanodots arrays are fabricated by anodic aluminum oxide (AAO) template mask which can have different structural parameters by varying anodization conditions. In this paper, the structural parameters of gold nanodots, which can be controlled by the diverse structures of AAO template mask, are investigated to enhance the optical properties of a-Si thin film solar cells. It is found that optical properties of the thin film solar cells are improved by finding optimization values of the structural parameters of the gold nanodot array.

Hydrogenated amorphous carbon (a-C:H) films were deposited by plasma enhanced chemical vapor deposition on silicon substrates. a-C:H thin film was irradiated to a typical He-Cd laser to study its emitting properties. The photoluminescence (PL) intensity during the irradiation achieved a maximum value when 2,000 seconds elapsed. Fourier transform infrared measurement revealed a-C:H thin film suffered transformation from a polymer-like to graphite-like phase during laser irradiation. Thermal annealing was done at various temperatures, ranging from room temperature to $400^{\circ}C$ in the atmosphere, to investigate structural changes in a-C:H film by heat generation during the emission. PL intensity of a-C:H thin film increased 1.5 times without apparent structural change, as annealing temperature increased up to $200^{\circ}C$. However, a-C:H film above $200^{\circ}C$ exhibited significant decrease of PL accompanying dehydrogenation. This led to a red shift of the PL peak.

본 연구에서는 스파/스킨 복합재 일체형 구조물 시편 제작을 통해 구조물 형상에 의한 국부적인 내부압력 구배 및 표면접착필름 적용 조건에 따른 복합재 내부 기공의 거동에 대하여 실험적으로 평가하였다. 표면접착 필름과 탄소섬유 프리프레그 소재의 점도특성 및 열분석 비교를 통해 경화특성 및 속도 차이를 확인하였다. 그리고 스파/스킨 일체형 구조물 시편을 표면접착필름 적용 조건에 따라 2가지 유형으로 성형 제작하여 표면상태검사, 비파괴 검사 및 파괴 검사를 통하여 검증하였다. 표면접착필름이 전체 표면에 적용된 시편#1의 경우 내부구조에 의한 압력 구배가 발생하고 이로 인해 낮은 압력이 적용되는 부위에서 형성된 기공들이 먼저 경화된 표면접착필름에 막혀 배출되지 못함을 확인할 수 있었으며, 표면접착필름이 적용되지 않아 탄소섬유 프리프레그가 전면 노출된 시편#2에서는 내부 기공이 완전히 배출됨을 볼 수 있었으며 미리 경화된 표면접착필름이 내부 기공 이동 및 배출에 있어서 차단막(Barrier film)으로 작용할 수 있음을 확인하였다.

The precise structural analysis of $SnO_{2}$ thin film, which was prepared by PECVD and thickness 2400 ${\AA}$, was tried to do the structural refinement using X -ray diffraction data. The observed diffraction patterns of $SnO_{2}$ thin film had the strongly preferred orientation effect. WIMV method was used to correct the preferred orientation effect. The final weighted R-factor, $R_{WD}$ was 7.92 %. The lattice parameters, a = b == 4.7366(1) ${\AA}$ and c = 3.1937(1) ${\AA}$, were almost in accordance with ones of $SnO_{2}$ powder.

We have studied structural, optical, and electrical properties of the Al-doped ZnO (AZO) thin films being usable in transparent conducting oxides. The AZO thin films were deposited on the corning 1737 glass plate by the RF magnetron sputtering system. To find optimal properties of AZO for transparent conducting oxides, the RF power in sputtering process was varied as 40 W, 60 W, and 80 W, respectively. As RF power increased, the crystallinity of AZO thin film was decreased, the optical bandgap of AZO thin film increased. The transmittance of the film was over 80% in the visible light range regardless of the changes in RF power. The measurement of Hall effect characterizes the whole thin film as n-type, and the electrical property was improved with increasing RF power. The structural, optical, and electrical properties of the AZO thin films were affected by Al dopant content in AZO thin film.
