초음파 스프레이를 이용하여 유리기판 위에 반사방지 박막이 제조되었다. GPTMS와 TEOS는 솔-젤 하이브리드 코팅 용액을 제조하기 위하여 사용되었다. 반사방지막의 코팅 두께를 제어하기 위하여 스프레이 노즐의 이동속도는 15~25 mm/s로 변경되었다. 스프레이 노즐의 이동속도가 증가 됨에 따라 반사방지막의 두께는 138 nm에서 86 nm로 감소되었다. 20 mm/s의 노즐 이동속도에 의해 제조된 반사방지막의 굴절률은 약 1.31, 막의 두께는 104 nm이며, 380 nm에서 780 nm의 가시광 영역에서의 평균 반사율은 0.75 %, 투과율은 94 %로 측정되었다.

Encapsulation of organic based devices is essential issue due to easy deterioration of organic material by water vapor. Atomic layer deposition (ALD) is a promising solution because of its low temperature deposition and quality of the deposited film. Moisture permeation has a mechanism to pass through defects, Thin Film Encapsulation using inorganic / organic / inorganic hybrid film has been used as promising technology. $Al_2O_3$ / Polymer / $Al_2O_3$ multilayer film has shown excellent environmental protection characteristics despite of thin thicknesses of the films.

Nowadays, Active Matrix Organic Light-Emitting Diodes (AM-OLEDs) are the superior display device due to their vivid full color, perfect video capability, light weight, low driving power, and potential flexibility. One of the advantages of AM-OLED over Liquid Crystal Display (LCD) lies in its flexibility. The potential flexibility of AM-OLED is not fully explored due to its sensitivity to moisture and oxygen which are readily present in atmosphere, and there are no flexible encapsulation layers available to protect these. Therefore, we come up with a new concept of Inorganic-Organic hybrid thin film as the encapsulation layer. Our Inorganic layer is Al2O3 and Organic layer is F-Alucone. We deposited these layers in vacuum state using Atomic Layer Deposition (ALD) and Molecular Layer Deposition (MLD) techniques. We found the results are comparable to commercial requirement of 10-6 g/m2 day for Water Vapor Transmission Rate (WVTR). Using ALD and MLD, we can control the exact thin film thickness and fabricate more dense films than chemical or physical vapor deposition methods. Moreover, this hybrid encapsulation layer potentially has both the flexibility of organic layers and superior protection properties of inorganic layer.

The transparent organic-inorganic hybrid films were prepared by the Sol-Gel process. PVP(polyvinylpyrrolidone) was used in organic component and TEOS(tetraethoxysilane) was used in inorganic component. HCI, $CH_{3}COOH$, and $NH_{4}OH$ were used as the Sol-Gel catalyst. The characteristics according to not only the variation of organic and inorganic contents but also the variation of catalyst species and contents were investigated. On the whole, the compatibility was remained between organic and inorganic components, and also as the TEOS contents were increased, mostly the transparency and the mechanical, thermal properties were improved. In addition, as content of catalysts was increased, the films showed characteristics that were closer to PVP than silica. Although the transparency of films was preserved in HCI and $CH_{3}COOH$, only the film containing more than 40wt% TEOS in $NH_{4}OH$ showed different phenomena.

Transparent color coating films were fabricated on a glass substrate by using sol-gel hybrid binder and organic dye. Sol-gel hybrid binder coating film fabricated with PTMS of 0.03 mole showed a very high pencil hardness of 9 H. As the withdrawal speed increased from 1.0 mm/s to 5.0 mm/sec, The yellowness ($b^*$) of coating glass also gradually increased. The transmittance of yellow color coating glass was 82.6% and the haze of coating glass was 0.35%. Red and blue color coating glasses also showed the high transmittance of 62.4% and 80.6% respectively. The surface hardness of color coating films was 6 H.

국내 영화 산업 매출은 매년 증가하고 있다. 극장은 영화의 1차 판매 경로이며, 극장을 이용하는 관객 수는 부가판권에 영향을 준다. 따라서 극장을 이용하는 관객의 수는 영화 산업 매출에 직결되는 중요한 요소이다. 본 논문에서 특정일의 관객 수를 예측하기 위하여 다중선형회귀모형과 Bass 모형을 결합한 Hybrid 모형을 고려한다. 두 모형을 결합함으로써 회귀분석의 예측값을 Bass 모형의 예측값으로 보정하였다. 분석에는 개봉일이 모두 다른 세 영화를 이용하였다. All subset regression 방법을 이용해 모든 가능한 조합을 생성하고 5중 교차검증(5-fold cross validation)을 통해 5번 모형을 추정한다. 이 때 제곱근평균오차가 가장 작은 모형으로 예측값을 구한 뒤 Bass 모형의 예측값과 결합해 최종 예측값을 구하게 된다. 과거데이터가 존재할수록 Bass 모형의 가중치는 증가하면서 예측값에 보정효과를 준다는 것을 확인할 수 있었다.

반도체 산업은 지속적으로 비약적인 발전을 이루어내면서 점점 고집적회로를 제작하기 위하여 패턴의 미세화가 이루어지게 되었다. 현재 미세 나노패턴의 형성을 위하여 여러층의 하드마스크가 사용되고 있으며, 화학증기증착(CVD)공정을 이용하여 형성한다. 이에 본 연구에서는 스핀공정(spin-on process)이 가능한 유-무기 하이브리드 중합체를 이용한 단일층의 하드마스크를 제작하였는데, 하드마스크 내의 무기계 성분이 감광층 보다 쉽게 식각되는 반면에 하드마스크의 유기계 성분으로 인해 substrate층 보다 덜 식각되었다. 유-무기 하이브리드 중합체를 이용한 하드마스크막의 광학 및 표면 특성을 조사하였고, 감광층과 하드마스크막의 식각비를 비교하여 유-무기소재의 하이브리드중합체에 대한 미세패턴을 형성시킬 수 있는 하드마스크막으로써의 유용성을 확인하였다.

Oblique angle deposition (OAD) is a physical vapor deposition where incident vapor flux arrives at non-normal angles. It has been known that tilting the substrate changes the properties of the film, which is thought to be a result of morphological change of the film. In this study, OAD has been applied to prepare single and multilayer TiN films by cathodic arc deposition. TiN films have been deposited on cold-rolled steel sheets and stainless steel sheet. The deposition angle as well as substrate temperature and substrate bias was changed to investigate their effects on the properties of TiN films. TiN films were analyzed by color difference meter, scanning electron microscopy, nanoindenter and x-ray diffraction. The color of TiN films was not much changed according to the deposition conditions. The slanted and zigzag structures were observed from the single and multilayer films. The relation between substrate tilting angle (${\alpha}$) and the growth column angle (${\beta}$) followed the equation of $tan{\alpha}=2tan{\beta}$. The indentation hardness of TiN films deposited by OAD was low compared with the ones prepared at normal angle. However, it has been found that $H^3/E^2$ ratio of 3-layer TiN films prepared at OAD condition was a little higher than the ones prepared at normal angle, which can confirm the robustness of prepared films.

This study was intended to investigate intertextuality expressed in fashion; intertextuality within fashion as sex, T.P.O., texture, and coordination and intertextuality between fashion and other genre like animation, music, film and technology. Intertextuality obtained by mixing the masculine and feminine text, coordinating various element without regarding T.P.O., texture has contributed to expending aesthetic realm and redefining the aesthetic value of traditional fashion design. The influence of animation, music, film on fashion and the interaction between these genre and fashion integrated high-class fashion and street-fashion, created the multicultural hybrid. Moreover according to the change of lifestyle the fashionable technical clothing was needed and developed. The intertextual tendency in the 21st-century fashion has given the new possibility of fashion design.

In past decades, the themal inkjet (TIJ) printer has been widely used as one of the most well-known digital printing technology due to its low cost, and high printing quality. Since the printing speed of TIJ printers are much slower than that of laser printers, however, there has been intensive efforts to raise the printing speed of TIJ printers. One of the most plausible methods to raise the printing speed of TIJ printers is to adopt a page-wide array TIJ printhead. To accomplish this goal, the high efficiency inkjet heating resistor films should be developed to settle the high power consumption problem of a page-wide array TIJ printhead. In this study, we investigated noble metal based multicomponent thin film resistor films prepared by atomic layer deposition (ALD) for a high efficiency inkjet printhead. Design concept, preparation, material properties of noble metal based multicomponent thin films will be discussed in terms of mutlfunctionality.
