There have been more demands for the culture and leisure activity services in the industry friendly to older adults. Of these culture and leisure activities, the activity of their watching TV programs and online media content has been on the increase. High-resolution display devices have become popular and are cheaper than before, and hardware for realizing multi-dimensional images can be easily configured. However, it is not easy to view high-resolution multi-dimensional images that reflect the physical and mental characteristics of the elderly. It is expected that the results of this study contributes to developing a variety of content for older adults’ culture and leisure activities with the use of reality image technology and promoting the industry friendly to older adults by developing.

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.

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

Higher education in Korea is faced with a new situation since 1981 when the government implemented a college graduation quota system designed to broaden the opportunities for higher education, alleviate the problem of the students who fail the entrance examination, and improve the quality of college graduates. The change of the system has brought about several serious problems including how to supply enough faculty members, how to provide enough educational facilities, and how to cope with the huge increase in the number of students, 30% more than graduation quota. The greatest single problem resulting from the implementation of college graduation quota system is the psychological and emotional unease aroused among the students, because 30% of those students with unsatisfying results must be banished from college before their graduation. This study aims to find effective measures for student guidance that each of the colleges can implement to help students adjust to the changed circumstances. After objectively investigating the problems from the various educational environments, from the recent students' views of college, and from the psychological and emotional unease arising in them by the fear of failing to graduate from their college because of implementation of the graduation quota system, a survey was conducted by means of a questionnaire composed of 40 questions and by means of personal interviews, 5,903 students, who are influenced by the graduation quota system, attending 19 public and private universities and colleges selected throughout the country. The data obtained from this survey were statistically processed with the help of the C. N. U. Computer Center, and the ratios of the responses to each of the questions were analyzed and calculated according to the distinctions of the total, sex, region, and major. The conclusions that the interrelations among the variant factors from each of the questions which were surveyed, analyzed and arranged have suggested are as follows : 1. The original purpose of graduation quota system should continually be clarified and communicated to all students and a concrete, specialized guidance system should be established to guide the minority of the students (13%) who don't fully understand the basic properties of higher educational institutions. 2. The institutions should provide enough educational facilities and supply enough faculty memebers to solve the problem of accomodating the large numbers of students. At the same time, they should suggest how students should learn positively and effectively to gain an expert knowledge, and how professors should gain public confidence in grade evaluation. Accompanying those measures, the government should develop a good policy to expand and distribute job opportunities to college graduates. 3. The admission quota should be controlled depending on the rate of naturally failed students, and then the students' unease and suppression caused by excessive competition can be relieved. In addition, it is advisable that the banished students should be allowed to transfer to University of the Air without regard to their grades. 4. An education devised to let students have a sound sense and way of thinking should be accompanied by a guidance system which their seniors, parents and society take part in. 5. An atmosphere conducive to sweet and well-rounded friendship among classmates should be created, sound extra-curricular activities should be encouraged and the number of students and adviser professor is in charge of should be lessened to a reasonable number.

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.
