Printing technology is accepted by appropriate technology that smart phones, tablet PC, display(LCD, OLED, etc.) precision recently in the electronics industry, the market grows, this process in the ongoing efforts to improve competitiveness through the development of innovative technologies. So printed electronics appeared by new concept. This technology development is applied on electronic components and circuits for the simplification of the production process and reduce processing costs. Low-temperature process making possible for widening, slimmer, lighter, and more flexible, plastic substrates, such as(flexible) easily by forming a thin film on a substrate has been studied. In the past, the formation of the electrode used a screen printing method. But the screen printing method is formation of fine patterns, high-speed printing, mass production is difficult. The roll-to-roll printing method as an alternative to screen printing to produce electronic devices by printing techniques that were used traditionally in the latest technology and processing techniques applied to precision control are very economical to implement fine-line printing equipment has been evaluated as. In order to function as electronic devices, especially the dozens of existing micro-level of non-dot print fine line printing is required, the line should not break at all, because according to the specifications required to fit the ink transfer conditions should be established. In this study of roll-to-roll printing conductive paste suitable for gravure offset printing by developing Ag paste for forming fine patterns to study the basic physical properties with the aim of this study were to.

Serviceability and durability of the concrete members can be seriously affected by the corrosion of steel rebar. Carbonation front and or chloride ingress can destroy the passive film on rebar and may set the corrosion (oxidation process). Depending on the level of oxidation (expansive corrosion products/rust) damage to the cover concrete takes place in the form of expansion, cracking and spalling or delamination. This makes the concrete unable to develop forces through bond and also become unprotected against further degradation from corrosion; and thus marks the end of service life for corrosion-affected structures. This paper presents an analytical model that predicts the weight loss of steel rebar and the corresponding time from onset of corrosion for the known corrosion rate and thus can be used for the determination of time to cover cracking in corrosion affected RC member. This model uses fully the thick-walled cylinder approach. The gradual crack propagation in radial directions (from inside) is considered when the circumferential tensile stresses at the inner surface of intact concrete have reached the tensile strength of concrete. The analysis is done separately with and without considering the stiffness of reinforcing steel and rust combine along with the assumption of zero residual strength of cracked concrete. The model accounts for the time required for corrosion products to fill a porous zone before they start inducing expansive pressure on the concrete surrounding the steel rebar. The capability of the model to produce the experimental trends is demonstrated by comparing the model's predictions with the results of experimental data published in the literature. The effect of considering the corroded reinforcing steel bar stiffness is demonstrated. A sensitivity analysis has also been carried out to show the influence of the various parameters. It has been found that material properties and their inter-relations significantly influence weight loss of rebar. Time to cover cracking from onset of corrosion for the same weight loss is influenced by corrosion rate and state of oxidation of corrosion product formed. Time to cover cracking from onset of corrosion is useful in making certain decisions pertaining to inspection, repair, rehabilitation, replacement and demolition of RC member/structure in corrosive environment.

국내 TV자연 다큐멘터리의 에필로그 시스템은 기존의 TV 다큐멘터리에서 볼 수 없었던 제작진의 모습을 기록한다. 이는 관조적 시선으로 본편의 제작과정을 다루던 메이킹 필름(makingfilm)과는 달리 제작진의 오지 촬영 과정에 서사성을 부여한다. 이러한 에필로그 시스템은 다큐멘터리의 본편에 비해 서사성이 강조되어 있으며 특히 제작진 개인의 미시적 서사를 다루면서 등장인물을 일종의 캐릭터로 기능하게 만들었다. 이에 본 논문에서는 에필로그 시스템의 서사적 특성을 살펴보기 위해 노스럽 프라이의 원형비평이론을 중심으로 <남극의 눈물>의 서사구조와 등장인물의 특성을 분석했다. <남극의 눈물>은 희극적 로망스의 서사구조와 희극적 등장인물의 특성을 통해 '자연과 인간의 화해'라는 주제를 이끌어냈으며, 이는 비극성을 중심으로 전개되던 자연 다큐멘터리 본편의 내용을 아울러 희극성을 통해 비극성을 극복한다고 볼 수 있다.

This study analyzed the characteristics of morphing in fashion design through the documentaries on morphing and fashion. The characteristics of morphing in fine art, media, and design area were categorized as reversible metamorphosis, sequential dissolve and blurring of interpolation boundaries. The results were as follow in fashion design. Reversible metamorphosis showed an automatic silhouette transformation by remote control, the metamorphosis of folding method by wearer's own movements and the automatic silhouette transformation by the air pressurizing method. It represented the thoughts of omnipotence as in the feeling of the magical world, the human desire for control in life, the rationalization of magical thinking and imaginative power, the creation of a new dress space and the extension of dress function. Sequential dissolve showed juxtaposition in the same area by the time order, juxtaposition in virtual space through the computer graphics, the series of fashion photography by steel cut of the dress making process and the blending of digital film and fashion design. It represented the approach for the storytelling of fashion show, implication of creative fashion design process and the creation of organic forms and the feeling of fantasy through artificial technology. The blurring of interpolation boundary showed an overlay of different fabrics with transparent boundaries, an overlay of different patterns with transparent boundaries and the blending of fabrics through the visual mixing of color. It represented the obfuscation of the object, the connotation of the space order, the connotation of the extensive and various meanings and the integrative property of objects.

The purpose of this study was to develop disposable diapers for the elderly in need by experimenting with wearing disposable diapers and analyzing the properties of materials of these diapers. The diapers were of two different types: one was a panty type for the elderly who were bed ridden, and the other was a pad type for the elderly who had incontinence. The subjects for the wearing test of the panty type were forty who were bed ridden, and there were forty subjects for the wearing test of the pad type who had incontinence. The disposable diapers for these experiments were chosen from those already found in the market place. Four panty types and three pad types were selected. From these experiments for the disposable diapers, the first prototypes were developed, and the second prototypes were proposed by experimenting with the first prototypes. The first panty prototype was designed to improve absorbing power, and we added waist rubber bands to prevent evacuation from back leaking and a frontal tape to prevent waistline film from tearing. The first pad prototype was designed to improve absorbing power also, and we added side rubber bands to prevent the side leaking and an adhesive tape on the fore part of the bottom to prevent the diapers from moving, and made the outline of the back area curved and thin to help hide the diaper from detection thus making the wearer feel better. From these test cases and analyzing the properties of materials with the first prototypes, we gained some success, but several points on further improvements were proposed to refine the final prototypes. The second panty prototype we proposed was to make 1he length longer, especially in the crotch area to prevent excess leaking and to fit the body more snugly. Also, the second pad prototype was proposed to reduce the total thickness of the diaper, and to improve the feeling and appearance.

영화 'X-men'은 변신(metamorphosis)을 주요 모티브로 등장인물과 배경의 시각효과를 만들어 내며 내러티브를 이끌어간다. 본 연구의 목적은 변신모티브가 슈퍼히어로 영화의 장르적 특징 중 하나로 '파타피직스(pataphysics)'의 가상성을 기반으로 구현되며, 재현된 새로운 가상성은 변신모티브 영화의 미학적 특성이 될 수 있음을 제시하고자 한다. 파타피직스는 20세기 중반 유럽에서 시작되어 기존의 전통에서 탈피한 부조리와 사회에 대한 풍자 등의 파타포의 은유적 상징에 의한 고유의 특성을 가진 가상성으로 다다이즘과 초현실주의, 팝아트, 포스트모더니즘으로 이어지는 예술운동에 큰 영향을 주었다. 이러한 예술 장르의 작품에 나타난 파타피직스의 특성을 분석하고 이를 토대로 영화에 나타난 변신장면에 적용하였다. 그 결과, 영화에 나타난 변신장면의 미학적 특성으로 슈퍼히어로의 외형과 내적인 힘의 양태를 시각화하며, 또한 기술적 가상성과 더불어 가상과 현실의 중첩으로 이루어진 파타피직스의 현전성, 혼종성, 탈정형성의 재현함을 고찰하였다.

Recently, According to companies of TFT LCD are making large sized products more and more. In the vortex of Products with a monitor and LCD TV is applied in a technique of a high viewing angle(FFS, IPS, VA). Also, as a high luminance, high speed response time, high degree of a color purity, and so on are continuing to develop a high performance, it is necessary to improve a specific character of high luminance that apply to LCD TV as a LCD BLU. Because a LCD panel for TV usually has a lower resolution that compare to a monitor, the structure of present backlight system can't put out its power even though it has a merit in transmission. Therefore, the examination of improvement about the high luminance direct typed BLU for LCD TV that presupposes several uses of CCFL(Cold Cathode Fluorescent Lamp) or EEFL(External Electrode Fluorescent Lamp)is actively being progressed. Although it is necessary to increase the number of lamps for applying high performance by the direct type, in this case, because we can design the character of luminance for adoption of high performance. We can satisfy with a level of luminance for LCD TV. Accordingly, we analyzed a change of the number of CCFL, mechanical and optical character to produce the direct typed backlight in 32inches spec. Consequently, we achieved luminance of 6597nit,which was including polarization film, and secured the standard for LCD TV.
