The research is aimed at theoretical substantiation, development and experimental verification of methods of applying mobile technologies by university students. The research objective implies adapting audience response systems and mobile tools of multimedia development to be used in the classroom environment at universities. The research object is application of mobile ICT to the training process. The research subject is methods of applying audience response systems and mobile tools to conducting practical classes at the university. There are analyzed Ukrainian and foreign researches into the issues of mobile ICT application to the university students training. The authors have developed methods of applying audience response systems by taking Plickers as an example and mobile tools of multimedia development through using augmented reality tools. There is comparative assessment of functionality of audience response systems and mobile tools of developing multimedia with augmented reality. Efficiency of the developed technology is experimentally verified and confirmed.

Actuality of surveillance the cyber-criminality problem and its impact upon a society is proved out by the rapid increase in a quantity of such crimes and material losses accordingly. The statistical analysis of their number increases and the caused losses is made in the process of cybercrimes studying. It’s revealed that besides the catastrophic number growth of such crimes, the relative size of losses is increased too. The analysis of the actual data for the nine years is made, on which basis the indicators’ table of the cyber-attacks number, the general losses and the indexes of their dynamics is elaborated. The analysis of the struggle’s state with cyber-criminality in our state is made. The recommendations are presented in the limits of the research for the increase of the information protection’s reliability.

The actual problem of the modern societycyber-criminality-is examined in the article. The classification of the "cyber-crime" notion is realized in the process of study of the cyber-crimes and the mechanisms of protection from the information security's threats. The list of the hardest cyber-crimes is composed, according to the presented classification. The comparative characteristics between the number of the registered cyberattacks and the losses from them is carried out. The analysis of the actual data for five years is exercised, on the basis of which the quantity indicators' table of cyber-attacks, general losses is elaborated and the cost of the cyber-attacks is calculated. The recommendations for the reliability's increase of the information protection are presented in the limits of the research.

The aim of the research leads to study optimization methods, modern software solutions for decision making with MatLab package and the GNU Octave package, and Microsoft Excel and LibreOffice Calc spreadsheets, as well as the formation of economic model and application of solution methods and optimization package to this model.
