This book is the result of the first International Conference ICT Innovations 2009. The ICT Innovations conference is the primary scientific action of the Macedonian Society on Information and Communication Technologies (ICT-ACT). It promotes the publication of scientific results of the international community related to innovative fundamental and applied research in ICT. Today, ICT has enlarged its horizons and it is practiced under multidisciplinary contexts that introduce new challenges to theore- cal and technical approaches. The ICT Innovations 2009 conference gathered academics, professionals and pr- titioners reporting their valuable experiences in developing solutions and systems in the industrial and business arena especially innovative commercial implementations, novel applications of technology, and experience in applying recent research advances to practical situations, in any ICT areas. The conference focuses on issues concerning a variety of ICT fields like: • Multimedia Information Systems • Artificial Intelligence • Pervasive and Ubiquitous Computing • Eco and Bio Informatics • Internet and Web Applications and Services • Wireless and Mobile Communications and Services • Computer Networks, Security and Cryptography • Distributed Systems, GRID and Cloud Computing ICT Innovations 2009 Conference was held in Ohrid, Macedonia, in September 28-30, 2009. Local arrangements provided by the members of the Macedonian Society on Information and Communication Technologies – ICT-ACT, mainly consisting of teaching and research staff of Computer Science Department at Faculty of Electrical Engineering and Information Technologies and Institute of Informatics at Faculty of Natural Sciences, both at Ss. Cyril and Methodius University in Skopje, Macedonia.

The serious illness of three presidents—Woodrow Wilson, Franklin Delano Roosevelt, and John F. Kennedy—as well as the injury Ronald Reagan received in the assassination attempt upon him have revealed our woefully inadequate system for handling presidential incapacity. The authors believe that this flawed system poses a major threat to the nation, and they provide sobering reports on how the government functioned (or failed to function) during times of presidential impairment. The public was kept in the dark regarding the gravity of the presidential condition, often unaware that critical decisions were being made while the president was suffering from a severe illness. Hidden Illness in the White House contains startling new information on the severity of Roosevelt’s illness during the crucial Yalta negotiations and the fact that Kennedy suffered from Addison’s disease, a life-threatening illness, long before he was elected to the presidency. In each case the authors demonstrate that a largely successful effort was made to conceal the president’s true medical condition from the public.
