디지털시대가 도래하면서 그래픽디자인의 영역이 확대되어 필름, DVD, 인터랙티브TV, 모바일, DMB 등 영상디자인의 새로운 분야들에서 디자이너의 역할을 요구하기 시작했다. 이는 보다 진화된 뉴미디어 환경을 기반으로 한다는 점에서 디지털 영상디자인의 적용과 사례로 볼 수 있다. 뉴미디어 환경은 젊은 계층이 주 타깃이 되기에 영상언어의 표현기법이 달라지는 것도 필연적이라고 하겠다. 시각커뮤니케이션이 창조되고 분배되어 온 방법들이 이제는 더 이상 정지되어 있는 것을 원하지 않고, 다이내믹한 움직임으로, 다시 상호작용(Interaction)이라는 변화를 거쳐오면서 영상의 적용과 활용은 비할 수 없이 다각화되었다. 변화와 발전을 거듭하는 학문으로서 디자인의 정체성이 뉴미디어 환경에서 어떻게 진화하고 있는지를 조사ㆍ분석하여 향후 영상ㆍ디지털미디어 대학원교육의 방향을 가늠하기 위한 것이 본 연구의 주된 목표이다. 이를 위해 사례조사 및 시각디자인 교육시스템에 대한 선행연구를 토대로 하여 디자인고등교육에 있어 합리적인 교육시스템의 방식을 수용자 조사를 통해 검증하고자 하였다. 본 연구는 영상ㆍ디지털미디어 분야의 고급인재 양성방안을 찾는 것을 목적으로, 이를 위해 기존의 디자인 교육과 디지털 영상교육의 융합으로 현실 사회의 요구에 부응하는 진화된 교육시스템을 도출하고, 사회의 요구를 앞서가는 디자인 고등교육기관으로서의 위상을 제시하고자 한다.

미국과 일본이 민간자율의 등급분류제도를 운영하고 있는 것과 달리 프랑스와 우리나라는 공공기관이 이 기능을 담당하고 있다. 하지만 제한상영관이 없는 제한상영가 등급의 문제점, 방송을 비롯한 매체들은 영화와 달리 사전심의를 받지 않는다는 점, 비용부담의 문제 등을 감안할 때 우리의 제도는 개선이 필요하고, 대안 중 하나가 등급분류기관을 민간자율로 전환하는 것이다. 민간자율의 등급분류제도 도입방법은 메이저 영화사들이 중심이 되어 등급분류협회를 설립하고 그 산하에 등급분류위원회를 두되 위원회 운영의 독립성을 보장하는 것이다. 정부는 저예산 예술영화의 심의료를 지원하고 청소년보호단체 등이 공정한 심의과정과 결과 준수를 감시하도록 지원할 필요가 있다. 영화산업이 등급분류제도의 민간자율화에 적극 나서지 않는 다는 사실이 가장 큰 걸림돌이지만, 표현의 자유 신장을 위해 합리적 방안을 찾는 노력이 필요하다.

Lineal and angular movements of many engine components make the lubricant absorb air and the aerated lubricant greatly influences the clearance performance of contacting behaviors of engine components such as big-end bearing, cam and tappet, etc. This study investigates the behaviors of aerated lubricant in the gap between con-rod bearing and proceeding which is one of the most frictional energy consuming components in the engine. Our assumption for the analysis of aerated lubricant film is that the film formation is influenced by the two major factors. One is the density characteristics of the lubricant due to the volume change of lubricant by absorbing the bubbles and the other is the viscosity characteristics of the lubricant due to the surface tension of the bubble in the lubricant. In our investigation, it is found that these two major factors surprisingly increase the load capacity in certain ranges of bubble sizes and densities. Frictional forces are also influenced by the aerated bubble size and density, which eventually enlarge the shear resistance due the surface tension, Modified Reynolds' equation is developed for the computation of fluid film pressure with the effects of aeration ratio under the dynamic loading condition. From the calculated load capacity by solving modified Reynolds' equation, proceeding locus is computed with Mobility method at each time step.

We have investigated the effect of the substrate temperature and hydrogen flow rate on the characteristics of IGZO thin films for the TCO (transparent conducting oxide). For this purpose, IGZO thin films were deposited by RF magnetron sputtering at room temperature and 300℃ with various H₂ flow rate. Experiments were carried out while varying the hydrogen gas flow rate from 0sccm to 1.0sccm in order to see how the hydrogen gas affects the IGZO thin films. IGZO thin films deposited at room temperature and 300℃ showed amorphous. The lowest resistivity value was 0.379×10^-5 Ωcm when the IGZO film was deposited at 300℃ and set up at 1.0sccm. As the oxygen vacancy rate increased, the resistivity intended to decrease. In conclusion, Oxygen vacancy affects the IGZO thin film's electrical characteristic.

IGZO thin films deposited at room temperature and 300℃ showed amorphous. The lowest resistivity value was 2125x10^-3 Ωcm when the IGZO film was deposited at RT and set up at 0.1sccm. As the oxygen vacancy rate decreased, the resistivity intended to increase. In conclusion, Oxygen vacancy affects the IGZO thin film's electrical characteristic.

Damage in film capacitors has been investigated, using FTIR and ESCA, aiming to elucidate the nature of electrode removal and the possibility of base films to be damaged. Also, tests were conducted to investigate the effect of a long-term thermal aging at elevated temperatures. Unsuccessful clearing or grape-clustering processes can induce a long-term degradation which involves the chemical and morphological changes. Major changes are the oxidation and the decrease in surface crystallinity possibly arising from the corona discharge. An immediate deterioration of BOPP film may occur when the air entrapped between the film layers induces an extensive autocatalytic oxidative degradation. This type of immediate damage may result in a premature failure at an early stage of qualification test. As far as the nature of electrode removal is concerned, a permanent removal of electrode materials was observed in the main erosion area.

Radiography에 있어서 피사체로부터의 산란 ${\gamma}$선은 film상의 상질을 나쁘게 하는 큰 요소중에 하나이다. 피사체로부터의 산란선량을 조사하기 위하여 여러가지 폭의 slit에 의한 조사장에서의 film의 흑화농도를 구했다. 또 그때의 투과측정기 검출감도의 양부도 검토했다. 피사체가 두꺼워지면 산란선량이 증가하여 결함검출도가 저하하지만, slit폭을 좁힘으로써 개선할 수가 있었다. 그러고 선원은 $_{60}$Co을 사용했고 시료는 철로서 실험을 했다.

Today, according to the temperature lowering of VLSI technology which have been required, the new thin film technology of low temperature have appeared. Plasma CVD method, one of low temperature technologies, have major problems with many interface trap defects. In this paper, we prepared ammonia free SiN film containing small H that acts as a defect impurity, and investigated the electrical properties of Laser assisted deposition film.

In CO₂ laser surface machining of plastic films in modern display manufacturing, scattering of fume particles could be a major source of well-recognized film surface contamination. This computational fluid dynamics research investigates the suction air flow patterns over a film surface as well as the dispersion of micron-sized fume particles with low-Reynolds number particle drag model. The numerical results show the recirculatory flow patterns near laser machining point on film surface and also over the surface of vertical suction slot, which may hinder the efficient removal of fume particles from film surface. The dispersion characteristics of fume particles with various particle size have been tested systematically under different levels of suction flow intensity. It is found that suction removal efficiency of fume particles heavily depends on the particle size in highly nonlinear manners and a higher degree of suction does not always results in more efficient particle removal.

This work analyzes the behaviors of aerated lubricant in the gap between con-rod bearing and journal. It is assumed that the film formation with aerated lubricant is influenced by the two major factors. One is the density characteristics of the lubricant due to the volume change of lubricant for the formation of bubbles and the other is the viscosity characteristics of the lubricant due to the surface tension of the bubble in the lubricant. These two major factors surprisingly increase the load capacity in some ranges of bubble sizes and densities. Modified Reynolds' equation is developed for the computation of fluid film pressure with the effects of aeration ratio in the lubricant. From the calculated load capacity by solving modified Reynolds' equation, journal locus is computed with Mobility method after comparing it with the applied load at each time step. The differences of journal orbits between aerated and pure lubricants are shown in the computed results.
