This book constitutes the refereed proceedings of the International Conferences on Security Technology, SecTech 2012, on Control and Automation, CA 2012, and CES-CUBE 2012, the International Conference on Circuits, Control, Communication, Electricity, Electronics, Energy, System, Signal and Simulation; all held in conjunction with GST 2012 on Jeju Island, Korea, in November/December 2012. The papers presented were carefully reviewed and selected from numerous submissions and focus on the various aspects of security technology, and control and automation, and circuits, control, communication, electricity, electronics, energy, system, signal and simulation.

As future generation information technology (FGIT) becomes specialized and fr- mented, it is easy to lose sight that many topics in FGIT have common threads and, because of this, advances in one discipline may be transmitted to others. Presentation of recent results obtained in different disciplines encourages this interchange for the advancement of FGIT as a whole. Of particular interest are hybrid solutions that c- bine ideas taken from multiple disciplines in order to achieve something more signi- cant than the sum of the individual parts. Through such hybrid philosophy, a new principle can be discovered, which has the propensity to propagate throughout mul- faceted disciplines. FGIT 2009 was the first mega-conference that attempted to follow the above idea of hybridization in FGIT in a form of multiple events related to particular disciplines of IT, conducted by separate scientific committees, but coordinated in order to expose the most important contributions. It included the following international conferences: Advanced Software Engineering and Its Applications (ASEA), Bio-Science and Bio-Technology (BSBT), Control and Automation (CA), Database Theory and Application (DTA), D- aster Recovery and Business Continuity (DRBC; published independently), Future G- eration Communication and Networking (FGCN) that was combined with Advanced Communication and Networking (ACN), Grid and Distributed Computing (GDC), M- timedia, Computer Graphics and Broadcasting (MulGraB), Security Technology (SecTech), Signal Processing, Image Processing and Pattern Recognition (SIP), and- and e-Service, Science and Technology (UNESST).

As computational science and engineering (CSE) become specialized and fragmented, it is easy to lose sight that many topics in CSE have common threads and because of this, advances in one sub-discipline may transmit to another. The presentation of - sults between different sub-disciplines of CSE encourages this interchange for the advancement of CSE as a whole. Of particular interest is the hybrid approach of c- bining ideas from one discipline with those of another to achieve a result that is more significant than the sum of the individual parts. Through this hybrid philosophy, a new or common principle can be discovered which has the propensity to propagate throughout this multifaceted discipline. This volume comprises the selection of extended versions of papers that were p- sented in their shortened form at the 2008 International Conference on Future Gene- tion Communication and Networking (http://www.sersc.org/FGCN2008/) and 2009 Advanced Science and Technology (http://www.sersc.org/AST2009/). We would like to acknowledge the great effort of all in the FGCN2008 and AST 2009 International Advisory Board and members of the International Program Committee, as well as all the organizations and individuals who supported the idea of publishing these advances in communication and networking, including SERSC (http://www.sersc.org/) and Springer. We would like to give special thanks to Rosslin John Robles, Maricel O. Balitanas, Farkhod Alisherov Alisherovish, Feruza Sattarova Yusfovna. These graduate school students of Hannam University attended to the editing process of this volume with great passion.

This volume constitutes the refereed proceedings of the International Conferences, FGCN and DCA 2012, held as part of the Future Generation Information Technology Conference, FGIT 2012, Kangwondo, Korea, in December 2012. The papers presented were carefully reviewed and selected from numerous submissions and focus on the various aspects of future generation communication and networking, and digital contents and applications.

As communication and networking (CN) become specialized and fragmented, it is easy to lose sight that many topics in CN have common threads and because of this, advances in one sub-discipline may transmit to another. The presentation of results between different sub-disciplines of CN encourages this interchange for the advan- ment of CN as a whole. Of particular interest is the hybrid approach of combining ideas from one discipline with those of another to achieve a result that is more signi- cant than the sum of the individual parts. Through this hybrid philosophy, a new or common principle can be discovered which has the propensity to propagate throu- out this multifaceted discipline. This volume comprises the selection of extended versions of papers that were p- sented in their shortened form at the 2008 International Conference on Future Gene- tion Communication and Networking (http: //www. sersc. org/FGCN2008/), Inter- tional Conference on Bio-Science and Bio-Technology (http: //www. sersc. org/ BSBT2008/), International Symposium on u- and e- Service, Science and Technology (http: //www. sersc. org/UNESST2008/), International Symposium on Database Theory and Application (http: //www. sersc. org/DTA2008/), International Symposium on Control and Automation (http: //www. sersc. org/CA2008/), International Symposium on Signal Processing, Image Processing and Pattern Recognition (http: //www. sersc. org/SIP2008/), International Symposium on Grid and Distributed Computing (ttp: //www. sersc. org/ GDC2008/), International Symposium on Smart Home (http: //www. sersc. org/SH2008/), and 2009 Advanced Science and Technology (http: //www. sersc. org/A
