지난 몇 년 동안 인터넷을 비롯한 각종 미디어 산업에서 사용자가 직접 제작한 콘텐츠라는 의미를 지닌 UCC(User Created Content)가 주목을 받았다. UCC는 사용자가 직접 이미지, 비디오 등의 형태로 제작한 콘텐츠를 말하는데, 이러한 UCC는 인터넷의 발달과 함께 크게 성장하게 되었으며 이제는 단순한 미디어나 콘텐츠로서가 아닌 하나의 산업으로 인정받기 시작했다. 또한 사용자와의 상호작용성과 체험적 형태를 지닌 상호작용 UCC가 등장함에 따라 이제는 UCC는 우리 생활과 밀접한 연관을 가진다고 할 수 있다. 이에 본 논문에서는 최근 들어 각광을 받고 있는 스마트폰을 활용하여 스마트폰과 상호작용 UCC와의 융합적 접근으로 스마트폰 터치스크린 안에서의 체험형 UCC를 어떻게 제작할 것인지를 알아본다. 기존의 컴퓨터의 모니터를 통해서만 상호작용이 가능하였던 점에서 탈피하여 공간적 제약을 극복하고 누구나 쉽게 이용할 수 있도록 기존 UCC와 새로운 스마트폰 터치스크린의 정보 기술과의 효과적인 융합에 초점을 맞추고자 한다. 그 동안의 UCC 파급효과를 보았듯이 UCC는 남녀노소 누구나 손쉽게 즐길 수 있다. 이러한 UCC가 최근 주목을 받고 있고, 사용자수가 급증하고 있는 터치스크린 기반의 스마트폰을 통해서 다시 한 번 UCC 시장에 활기를 불어넣을 수 있는 방안을 제시한다. 또한 상호작용 UCC를 통해서 기존의 UCC 매체인 모니터를 이용하여 전달하고자 하는 것보다, 스마트폰의 장점과 강력한 특징인 터치스크린을 잘 살려 스마트폰을 통해 보다 효율적으로 전달할 수 있는 방안을 제시한다.

With the advent of smartphones, people can access various information through the internet anytime and anywhere. Even in the vehicle environment, users can use the internet. Users interact with web and applications every day and get information. However, as the amount of data to be processed by the program increases, users inevitably receive a message to wait. User waiting is an inconvenient experience, but minimizing user waiting is the best way because there is time required for data processing. However, if the service processing time exceeds the expected time, users experience more severe boredom and pain. Therefore, various methods and researches are being conducted to alleviate the boredom of user waiting. The most commonly used method to alleviate user waiting boredom is loading. In this study, we investigated the effect of skeleton loading, the latest loading technique, on user waiting experience, and how attractive it is as a design technique in terms of UI compared to other loading techniques.

Linear Algebra are arguably the most popular math subjects in colleges. We believe that students' learning and understanding of linear algebra can be improved substantially if we incorporate the latest advanced information technologies in our teaching. We found that the open source mathematics program 'Sage' (http://sagemath.org) can be a good candidate to achieve our goal of improving students' interest and learning of linear algebra. In particular, we developed a simple mobile content which is available for Sage commands on common cell phones in 2009. In this paper, we introduce the mobile Sage which contains many Sage functions on a smart-phone and the mobile linear algebra content model(lecture notes, and video lectures, problem solving, and CAS tools) and it will be useful to students for self-directed learning in college mathematics education.
