무용과 영상 테크놀러지의 결합으로 시작된 무용영화는 새로운 장르로 자리매김하며 발전되어오고 있다. 해외에서는 이미 1950년대부터 실험적인 무용영화가 창작되었고 댄스필름협회가 조직되었으며 많은 무용영화제가 개최되고 있다. 그러나 국내에서 무용영화라는 장르에 대한 인식과 창작활동이 본격적으로 시작된 것은 얼마 되지 않았다. 이러한 상황 속에서 '서울무용영화제' 개최와 '댄스필름 프로젝트'의 창작적 실험은 국내의 무용영화 발전에 중요하다. 따라서 본 논문에서는 무용영화에 대한 개념과 발전과정, 해외 여러 무용영화제와 '서울무용영화제'의 현황과 특징을 살펴보고, '서울무용영화제'와 '댄스필름 프로젝트'의 역할과 기능, 그리고 이들의 협업으로 인한 기대효과를 분석하며 국내 무용영화의 발전 가능성에 대해 논의했다. '댄스필름 프로젝트'는 댄스필름 제작의 교육과 실험의 장으로, '서울무용영화제'는 무용영화 제작자 발굴, 작품 상영, 관객과의 대화, 국제교류, 유통 등의 플랫폼이 된다. 무용영화제는 무용영화의 과거와 현재의 흐름을 인식하고 미래를 전망해 볼 수 있는 살아있는 컨텐츠로서의 가치를 내재하고 있다. 이 두 단체의 상생과 발전은 국내 무용영화 발전에 긍정적인 역할을 다 할 것이라 기대된다.

In this paper, we present a novel hydrophilic coating material (Wellture Finetech, Korea) which can be utilized as a coating layer for anti-contamination for electrical and electronic system. The coating material was deposited on 4 inch silicon wafer with several different film thickness. The film thickness was controlled by spin coating speed. After curing of the film, we have scratched by permanent marker to check self-cleaning property of the film. Also we have executed several mechanical tests of the films. As the spin coating speed is increased, the film thickness was thinned from 230 nm to 125 nm. Contact angle of the film was lowered from $30^{\circ}$ to $12^{\circ}$ as the spin coating speed is increased from 700 to 2,500 rpm. On permanent marker scratched film surface coated at 1,000 rpm, we have poured regular city water to investigate self cleaning property of the film. The scratches were gradually separated from the film surface due to super-hydrophilicity of the film. Hardness of spin coated film was 9H measured by ASTM D3363 method. and adhesion of all film was 5B tested by ASTM D3359 method. Also, to get exact hardness value of the film, we have utilized a nano-indenter. As spin speed is increased, the hardness of film was increased from 3 GPa to 5 GPa.

Vacuum-assisted thermoforming is one of the critical steps for the successful application of film insert molding(FIM) to parts of complex shapes. If the thickness distribution of the formed film is non-uniform, cracking, deformation, warping, and wrinkling can easily occur at the injection molding stage. In this study, the effects of processing parameters, which include the film heating time, plug depth, plug speed and vacuum delay time, on film thickness distribution were investigated. It was found that the film thickness at the part sidewall decreases with increasing the film heating time and plug depth, but the thickness at the bottom was found to exhibit the opposite behavior. The film thickness of the sidewall was observed to increase at higher plug speed and vacuum delay time of 0 ~ 0.3sec.

Many computational researches have been performed about EHL film thickness in the contact between cam and follower in the engine valve train system. However, those computations do not explain the characteristics of dynamic film thickness which means squeeze film effect. Without the consideration of transient term in the Reynold's equation, the predicted film thickness from steady state condition has large difference from the actual film thickness. In this study, we have investigated the kinematic and dynamic simulations of rocker-arm valve train system. From the dynamic simulation, the applied load and the entraining velocity of the lubricant between cam and follower are obtained and with these values the dynamic film thickness is computed by Newton-Raphson method and compared with the steady state film thickness.

In this study, residual stress distribution in multi-stacked film by MEMS (Micro-Electro Mechanical System) process is predicted using Finite Element method (FEM). We evelop a finite element program for residual stress analysis (RESA) in multi-stacked film. The RESA predicts the distribution of residual stress field in multi-stacked film. Curvatures of multi­stacked film and single layers which consist of the multi-stacked film are used as the input to the RESA. To measure those curvatures is easier than to measure a distribution of residual stress. To verify the RESA, mean stresses and stress gradients of single and multi layers are measured. The mean stresses are calculated from curvatures of deposited wafer by using Stoney's equation. The stress gradients are calculated from the vertical deflection at the end of cantilever beam. To measure the mean stress of each layer in multi-stacked film, we measure the curvature of wafer with the left film after etching layer by layer in multi-stacked film.

The effect of pre-existing barrier-type film on porous aluminum oxide film formation during anodization was investigated to control the uniform film growth rate. Initial potential fluctuations during anodization indicated that the breakdown of barrier-film is preceded before the porous formation and the induction time for the porous film growth increases with the increases of pre-existing film thickness. The porous film growth mechanism is lot affected by the presence of barrier film on aluminum surface. In parallel, uniform growth of barrier film underneath the porous structure was attained by two-step anodization processes.

For the increase the charge stability of teflon electrets for used at uncomfortable industrial circumstances with high temperature or humidity, We made an investigation into double layer effect of teflon electrets. Teflon AF film was spincoated on FEP film and then the charge storage property of AF/FEP dual film was investigated to be compared with FEP film. It was found that the AF/FEP dual film has higher surface potential than FEP film on the repeated charging and annealing process. It seems that AF/FEP dual film has higher thermal stability than FEP film through TSC measurement. If the investigations of the double layer effect of Teflon film carried out more closely with it's molecular structures and surface conditions, it may be effectively improved the stability of charge storage.

Methacrylic acid was graft polymerized with benzoyl peroxide in itiator onto the commercial PET film. Graft polymerization was carried out in emulsion, which consisted of BPO (1), chlorobenzene(8) as swelling agent, tween 80(1) and sodium lauryl sulfate(1) as emulsifier and water(1,000). Original PET film has poor reactivities and, so the film preswdled with benzyl alcohol($150^{\circ}C$, 1hr) was also examined. The graft yield of PET film was increased with reaction temperature and monomer concentration. The graft yield of preswelled PET film was higher than that of no-treated PET film. Moisture regain was linearly increased with graft yield. DSC thermodiagram showed the Tm of grafted PET film was same as that of original PET film. Grafted PET film was dyed with methylene blue solution. The photograph of the cross section showed that grafting was occured not at the center but near surfaces.
