Ubiquitous computing is emerging as a new paradigm in next-generation information technology. This new paradigm has been embodied into tremendous business models and applications through lots of ubiquity-related technologies. In this study, a new taxonomy for these business applications and technologies is suggested. In order to prove the practical values, two case applications of the taxonomy are conducted. In the cases, 24 ubiquitous computing services and 19 ubiquitous computing projects are classified so that the status quo of ubiquitous computing is analyzed.

The term "color temperature" represents the color of light source or the white point of image displaying devices such as TV and PC monitor. In this paper, our goal is to find an appropriate method of converting the color temperature in order to reproduce the userpreferred color temperature in video displaying devices. In order to achieve the goal, we experiment human's preference tendency towards the color temperature and then propose an adaptive color temperature conversion method reflecting estimated tendency.

As Ubiquitous Technology is emerging as a new paradigm of information technology industry, business environment has been more complicated. According to this change, many enterprises have focused establishing a Business Model (BM) for creating a new value. Therefore, the importance of developing a suitable Business Model has been increasing more and more. In this research, we suggested the Business Model Feasibility Analysis (BMFA) framework for evaluating a BM. Also, in order to suggest methodology applications, it was applied to portable internet, called Wibro business model. This study is meaningful in suggesting integrated perspective analyzing business model in technology, strategy and market view in ubiquitous technology environments and concretizing the application of framework by case study for portable internet business models. 2007 International Conference on Convergence Information Technology 0-7695-3038-9/07 $25.00
