이러닝 학습은 다양한 목적을 지닌 많은 대상들에게 눈부실만한 기여를 하고 있음에도 불구하고 이러닝의 특성을 가장 절실히 필요로 하는 장애인과 노인 등의 소외된 사람들에게 혜택을 주지 못하고 있다는 점은 안타까운 일이다. 이러한 현실에 대하여, 그동안 정보통신기술분야에서도 소외된 대상들을 고려한 접근성 관련 제도적 개선이 이루어져 왔다는 점을 상기한다면, 자성만이 아니라 그 이유를 조사할 필요가 있다. 따라서 본 연구의 목적은 이러닝 기업 CEO의 인식을 조사하여 웹 접근성과 관련한 제도적인 여건 속에서도 학습 환경에서는 여전히 접근성 개선이 이루어지지 않는 이유를 찾아보고 개선 방안을 제시하는 데 있다. 위의 목적을 위하여 현업에 종사하는 운영자와 개발자들을 대상으로 보편적 교수 설계을 위한 이러닝의 접근성 관련 인식을 조사하였다, 그 결과 이러닝 접근성에 대한 CEO의 인식은 매우 저조하며, 중요성에 대해서는 공감하나 비용적인 부담으로 인해 보편적 이러닝 콘텐츠 개발은 불가능하다고 생각하고 있었다. 이러닝 기업 CEO의 낮은 인식은 곧 개발자와 교수설계자들에게 접근성 기술 적용의 필요성을 강조하지 않는 결과를 초래하고 있다. 이에 대한 개선을 위해서는 우선 정부와 관련기관의 적극적인 홍보와 제도적 장치가 필수적이며, 현재 제공되는 이러닝의 접근성 개선을 위한 연구와 지원방안이 필요하며, 구체적으로는 보편적 학습설계와 접근성에 대한 교육과 확산을 위한 대안이 필요하다.

The purpose of this research is to explore the explanatory factors of preference for the universality of the welfare system at the time of expanding the welfare system. In particular, considering endogenous problem that may occur in the process of analyzing the causal relationship between subjective perception and preference for welfare policy, the 2SLS regression analysis using instrument variables was attempted in this research. The key findings of this research were as follow. First, the groups who are opposed to the welfare state expansion, for example high income earners, low risk group, and employer/self-employer, prefer the more universal welfare systems. Second, the negative perception of welfare policy and recipients, which is stronger in older generation who experienced a much longer period of industrializaion, have a negative effect on preference for the universal welfare system. Last, we find that the endogenous problem arise in this research and distort the estimated regression coefficients. Therefore, subsequent studies must be mindful of this problem when they explain attitudes with attitudes.

As a human identification technique, gait recognition has recently gained significant attention. Silhouette-based gait recognition is one of the most popular methods. This paper aims to investigate features that determine the style of walking in silhouette-based gait recognition. Gait can be represented using two cues: static(shape) cue and dynamic(motion) cue. Most recently, research results have been reported in the literature that the characteristics of gait are mainly determined by static cue but not affected by dynamic cue. Unlike this, experimental results in this paper verifies that dynamic cue is as important as and in many cases more important than static cue. For experiments, we use two well-blown gait databases: UBC DB and Southampton Small DB. The images of UBC DB correspond to the 'ordinary' style of walking. The images of Southampton Small DB correspond to the 'disguised' (not ordinary by wearing special clothes or bags) style of walking. As results of experiments, the recognition rate was 100% by static cue and $95.2\%$ by dynamic cue for the images of UBC DB. For the images of Southampton Small DB, the recognition rate was $50.0\%$ by static cue and $55.8\%$ by dynamic cue. The risk against correct recognition was 0.91 by static cue and 0.97 by dynamic cue for the images of UBC DB. For the images of Southampton Small DB, the risk was 0.98 by static cue and 0.98 by dynamic cue. Consequently, the characteristics of ordinary gait are mainly determined by static cue but that of disguised gait by dynamic cue.

The purpose of this research was to provide the information needed for improving the elderly housing education and the elderly housing contents of Technology and Home Economics textbook. Thus, the elderly housing contents of current Technology and Home Economics textbook were categorized. Then, a total of 233 teachers were surveyed to examine their importance perception on the elderly housing contents. Elderly housing contents were grouped into S categories, each of which was named 'safety and safety management', 'room plan for the elderly', 'shrinking stage in family life cycle and dependency stage in housing life cycle','a house for 3-generation extended family', and 'universal design'. Teachers' importance perception was generally high for 'safety and safety management' and especially for 'safety and safety management' of bathroom(protection against slippery floor, safety bar, the appropriate position and height of shower, bathtub, and wash stand) ; the basic guidelines of 'room plan for the elderly'(emergency call, closely located bathroom, flat and non-slippery floor) ; the general guidelines during shrinking stage in family life cycle and dependency stage in housing life cycle'(protection equipments against safety accident, emergency call, flat and non-slippery floor) ; independent life among 3-generation extended family members(bathroom for the elderly, space plan for independent life among extended family members) ; the basic design guidelines of universal design(safety bar in bathroom, flat floor) and the guidelines of universal design which were especially helpful for wheelchair users(enough empty space in front of door and in corridor, wide door and corridor). Recommendations for the elderly housing education and the elderly housing contents of Technology and Home Economics textbook were that 'emergency call','safety bar in bathroom' and 'flat and non-slippery floor' were the most basic guidelines for elderly housing; that 'enough empty space in front of door and in corridor', 'wide door and corridor', 'low and wide steps', 'ramp for wheelchair users' and 'D-type or lever-type door handle' were most recommendable guidelines for universal design; that 'need for elderly housing', 'types of elderly housing', 'alternatives and choices of dependency stage in housing life cycle' and 'house plans for shrinking stage in family life cycle' were required guidelines for increasing elderly-only family.

Big data is gradually expanding in diverse fields, with changing the data-related legislation. Moreover it would be interest in big data education. However, it requires a high level of knowledge and skills in order to utilize Big Data and it takes a long time for education spends a lot of money for training. We study that in order to define Universal Big Data used to the industrial field in a wide range. As a result, we make the paradigm for Big Data education for college students. We survey to the professional the Big Data definition and the Big Data perception. According to the survey, the Big Data related-professional recognize that is a wider definition than Computer Science Big Data is. Also they recognize that the Big Data Processing dose not be required Big Data Processing Frameworks or High Performance Computers. This means that in order to educate Big Data, it is necessary to focus on the analysis methods and application methods of Universal Big Data rather than computer science (Engineering) knowledge and skills. Based on the our research, we propose the Universal Big Data education on the new paradigm.

인간의 경험에 대한 지각은 다양하다. 일차원적인 직접 경험에 대한 것은 확신의 문제이다. 또한 보편적인 다른 경험은 알게 되면서 인식하는 또 다른 경험의 결과이다. 미디어에서 또한 리얼리티의 담화 작용을 통해 수용자에게 경험에 대한 인식과 가치를 제공하고, 새로운 간접 경험에 대한 경험을 재현을 통해서 그 의미를 전달하고 있다. 그러므로 본 연구에서는 리얼리티의 담화작용과 의미전달에 있어서 수용자의 믿음적 상징체계의 특성과 사회문화적 현상을 고찰하고자 한다.
