UCMA 2011

We would like to welcome you to the proceedings of the 2011 International Conference on Ubiquitous Computing and Multimedia Applications (UCMA 2011) which was held during April 13-15, 2011, at Hannam University, Daejeon, Korea.
UCMA 2011 is focused on various aspects of advances in multimedia applica- tions and ubiquitous computing with computational sciences, mathematics and information technology. It provided a chance for academic and industry pro- fessionals to discuss recent progress in the related areas. We expect that the conference and its publications will be a trigger for further related research and technology improvements in this important subject. We would like to acknowl- edge the great effort of all the Chairs and members of the Program Committee. Out of around 570 submissions to UCMA 2011, we accepted 86 papers to be included in the proceedings and presented during the conference. This gives an acceptance ratio firmly below 20%. Regular conference papers can be found in this volume while Special Session papers can be found in CCIS 151.
