The development of the information sphere and the corresponding increase in its volume and cost is accompanied by the introduction of advanced information technologies in all spheres of public life of the state, which leads to an increase in the frequency of attacks and potential losses from information leakage. As a result, the complexity of protection systems and an increase in their cost. In these conditions, the task to efficiently distribute limited financial resources to protect the information of business entities becomes more and more important and largely determines the level of financial and economic security of the enterprise and the state as a whole. Of particular relevance is the development of issues of optimisation of indicators of the information security system in a dynamic confrontation. Such indicators can be the amount of damage caused from the implementation of information threats, which determines the effectiveness of the protection system, the profit from making investments in information protection, their profitability, and the like. It was established that it is necessary to determine the total amount of protection resources, which minimises the total losses from possible information leakage in conditions of instability. The authors believe that the optimal control mechanism is the distribution of resources between objects that contain a different share of information and are distinguished by natural security, dynamic vulnerability, and the probability of an attack with the allocation of a certain amount of resources. The practical significance of the study lies in determining the optimal moment for the introduction of defence resources – after the direction and intensity of attacks and, accordingly, the possible level of losses was clarified.

It is currently believed that ciliary beating results from microtubule sliding which is restricted in regions to cause bending. Cilia beat can be modified to bring about changes in beat frequency, cessation of beat and reversal in beat direction. In ciliated protozoans these modifications which determine swimming behavior have been shown to be related to intracellular (intraciliary) Ca2+ concentrations. The Ca2+ levels are in turn governed by the surface ciliary membrane which exhibits increased Ca2+ conductance (permeability) in response to depolarization. Mutants with altered behaviors have been isolated. Pawn mutants fail to exhibit reversal of the effective stroke of ciliary beat and therefore cannot swim backward. They lack the increased inward Ca2+ current in response to depolarizing stimuli. Both normal and pawn Paramecium made leaky to Ca2+ by Triton extrac¬tion of the surface membrane exhibit backward swimming only in reactivating solutions containing greater than IO-6 M Ca2+ Thus in pawns the ciliary reversal mechanism itself is left operational and only the control mechanism at the membrane is affected. The topographic location of voltage-dependent Ca2+ channels has been identified as a component of the ciliary mem¬brane since the inward Ca2+ conductance response is eliminated by deciliation and the return of the response occurs during cilia regeneration. Since the ciliary membrane has been impli¬cated in the control of Ca2+ levels in the cilium and therefore is the site of at least one kind of control of microtubule sliding, we have focused our attention on understanding the structure and function of the membrane.

SummaryTwo reactions of the extrinsic pathway of coagulation, the activations of Factor X and prothrombin, have been studied in purified systems and shown to be self-damping. Factor X was activated by the tissue factor - Factor VII complex, and prothrombin by two systems: the coagulant protein of Taipan venom, and the physiological complex of activated Factor X, Factor V, lipid, and calcium ions. In each case the yield of enzyme, activated Factor X or thrombin, is a function of the concentration of activator. These and other observations are considered as a basis for a control mechanism in coagulation.

The article proposes a model for forecasting the success of student’s learning. The model is a Markov process with continuous time, such as the process of “death and reproduction”. As the parameters of the process, the intensities of the processes of obtaining and assimilating information are offered, and the intensity of the process of assimilating information takes into account the attitude of the student to the subject being studied. As a result of applying the model, it is possible for each student to determine the probability of a given formation of ownership of the material being studied in the near future. Thus, in the presence of an automated information system of the university, the implementation of the model is an element of the decision support system by all participants in the educational process. The examples given in the article are the results of an experiment conducted at the Institute of Space and Information Technologies of Siberian Federal University under conditions of blended learning, that is, under conditions when classroom work is accompanied by independent work with electronic resources.

The article considers the feasibility of integrating artificial intelligence technologies into school education and identifies a problem in identifying didactic elements in the field of artificial intelligence, which must be mastered in a school informatics course. The purpose of the article is to propose variant of the content of teaching the elements of artificial intelligence for the general education of schoolchildren as part of the curricular and extracurricular activities in informatics. An analysis of the psychological, pedagogical and scientific-methodical literature in the field of artificial intelligence made it possible to identify the appropriateness of teaching schoolchildren the elements of artificial intelligence in the framework of a comprehensive informatics course, as the theoretical foundations of modern information technologies. Summarizing and systematizing the learning experience of schoolchildren in the field of artificial intelligence made it possible to form variant of the content of teaching the elements of artificial intelligence, which can be implemented in a compulsory informatics course for 9th grade, as well as in elective classes. The results of the study are the theoretical basis for the further development of the components of the methodological system of teaching the elements of artificial intelligence in a school informatics course. The research materials may be useful to specialists in the field of teaching informatics and to informatics teachers.

The article discusses the prospects of role-playing games in the educational process to increase students’ motivation and involvement, as well as the possibility of modern information technologies (primarily social networks) for constructing innovative forms of such games. The author’s format of the live-action role-playing game is presented. It was developed and tested at the Saratov State University. It involves the integration of numerous educational tasks into a single plot, within which each participant plays a role and communicates with other participants to complete tasks. The main interaction, plot development and group activities occur in dialogs, conversations and groups of social networks. This approach has shown its viability in teaching legal disciplines, and also has prospects for use in IT education.
