Digital signage employs Digital Information Display technology to deliver visual information. As a convergence platform of network and display, it is aimed at display or advertising in diverse places and situations. At present, for high definition, most large digital signage content images are produced with the uses of motion graphic based imaging technique or 3D animation technique. These images face a limited range of use due to degradation. The purpose of this study is to look into the production method to apply high-definition reality images with minimum degradation to digital signage by using timelapse technique. The reality images shot in this study are expected to be screened on digital signage without degradation. Key Words : Digital Signage, Time-lapse, Multimedia Contents, VFX, Editing, Motion Picture

Multi-vision such as Digital Signage and Screen-X, having overcome the limits of a wide image, have been providing audiences with a sense of immersion as a film delivering stories through over 3-sided screen without requiring special devices. However, a number of film producers consider such multi-vision one of the difficult systems to have access to due to their stutter phenomenon, limits of stitching process and complicated system environments. In this thesis, the technical issues and characteristics related to the actualization of multi-images were examined and the optimized screen organization and directing methods were explored to propose a guideline that can be used to have convenient access to multi-vision contents for the production of high-resolution Digital Signage content. Based on the results acquired through this research, it was expected that Digital Signage systems such as multi-vision and Screen X can be recognized as a popular medium capable of providing audiences with a sense of immersion in the process of appreciating different-dimensional realistic images. Key Words : Multi-vision, Realistic Image, Panorama, Match Correction, Screen X
Ta₂O_(5) 게이트 pH-ISFET의 제조 및 그 동작특성
권대혁,김명규,이광만,손병기 경북대학교 센서기술연구소 1991 센서技術學術大會論文集 Vol.2 No.1
To improve sensing characteristics of the pH-ISFET using LPCVD-grown Si_(3)N_(4), Ta_(2)O_(5) thin film depositied by RF reactive sputtering was used for hydrogen ion sensing gate and investigated sensing characteristics at various annealing temperatures. The XRD pattern showed that the crystal structure of the Ta20s thin film was amorphous when the annealing temperature was less than 500℃, δ-Ta_(2)O_(5) poly-crystal at MC Ta_(2)O_(5) gate pH-ISFET annealed at 400℃, O_(2) ambient for 1hour, the AES and RBS spectrum showed good stoichiometry (O/Ta=2.5). And its sensing characteristics showed good linearity and high sensitivity(57~59MV/pH) in the wide pH range(pH 2~12), and excellent long-term stability (0.03~0.05 pH/day). It can be concluded from these results that the sensing characteristics of Ta_(2)O_(5) gate pH-ISFET is more excellent than Si_(3)N_(4) gate pH-ISFET.
自己認識과 自己尊重의 儒家的 意味 : with particular Mencian discourse 孟子의 論議를 중심으로

In this study, a through review of the meaning of self-knowledge and self-respect advocated by Mencius(孟子:371~289 B.C.) was attempted for re-illuminating Mencian thoughts in the light of modern system of character education. Mencius maintained the structure of Confucius's original vision, but set it upon a new foundation: a subtle yet powerful theory about human nature. We can see Mencius's philosophical views as part of the emerging debate about the true character of human nature. Mencius believed that, by nature, human beings are inclined toward the good, and that if we accord with this inclination we will develop into full moral beings and fulfill the grand Confucian vision. Mencius in honored for his inheritance of the orthodox doctrines of Confucian ethics. In particular, the essential features of Mencius's view on human nature is exemplified in admission of the good nature endowed by heaven. His view is epitomized in four sprouts(四端), namely, benevolence, righteousness, propriety, and wisdom. Mencius explicitly linked the task of self-cultivation with the development of one's Heavenly conferred nature. In Mencius, Education as a self-cultivation is therefore instrumental in development of the given potential of human nature by cultivation of the inherent good intellect and good faculty in commensuration with the teaching displayed in the doctrines of Confucian ethics and morality. furthermore, emphasis of mental displine is an indispensable component of the instructional program as noted in review of the educational concept of Mencius. for this undertaking, he advocated the art in 'seek for the lost mind'(求放心), 'holding one's mind'(存心), and 'nourishing one's nature'(養性) base on "getting or finding the way in oneself"(自得). In sum, his thoughts of the human nature and of self-cultivation are very suggestive on groping for the direction of the contemporary character education.
