[Annotatie]: This book constitutes the refereed joint proceedings of four co-located international conferences, concertedly held in Miyazaki, Japan, in June 2010. The papers in this volume were selected based on their scores obtained from the independent reviewing processes at particular conferences, and their relevance to the idea of constructing hybrid solution to address the real-world challenges of IT. It provides a chance for academic and industry professionals to catch up on recent progress in the related areas. The 49 revised full papers presented were carefully reviewed and selected during two rounds of reviewing and improvement from more than 1000 initial submissions. The papers emanate from the four following international conferences: Information Security and Assurance (ISA 2010), Advanced Communication and Networking (ACN 2010), Advanced Science and Technology (AST 2010), and Ubiquitous Computing and ultimedia Applications (UCMA 2010). This volume focuses on various aspects of advance [Flaptekst]: Advanced Science and Technology, Advanced Communication and Networking, Information Security and Assurance, Ubiquitous Computing and Multimedia Appli- tions are conferences that attract many academic and industry professionals. The goal of these co-located conferences is to bring together researchers from academia and industry as well as practitioners to share ideas, problems and solutions relating to the multifaceted aspects of advanced science and technology, advanced communication and networking, information security and assurance, ubiquitous computing and m- timedia applications. This co-located event included the following conferences: AST 2010 (The second International Conference on Advanced Science and Technology), ACN 2010 (The second International Conference on Advanced Communication and Networking), ISA 2010 (The 4th International Conference on Information Security and Assurance) and UCMA 2010 (The 2010 International Conference on Ubiquitous Computing and Multimedia Applications). We would like to express our gratitude to all of the authors of submitted papers and to all attendees, for their contributions and participation. We believe in the need for continuing this undertaking in the future. We acknowledge the great effort of all the Chairs and the members of advisory boards and Program Committees of the above-listed events, who selected 15% of over 1,000 submissions, following a rigorous peer-review process.
