Media theory is a new branch of discrete applied mathematics originally developed in mid-nineties to deal with stochastic evolution of preference relations in political science and mathematical psychology. However, many different examples of media can be found, ranging from learning spaces to hypercube computers, suggesting that this concept is ubiquitous. The paper presents very basic concepts and results of media theory and is aimed at a wide body of researchers in discrete applied mathematics. ; Peer Reviewed

Relevance. In order to prevent and eliminate such modern challenges as pandemics, local wars, man-made disasters, it is necessary to accelerate the introduction of digital technologies into public administration processes. This creates a need for the development of digital competencies of Russian civil servants. Research on this topic in scientific publications is limited and fragmentary. There is a request for the development of scientifically-based and practically applicable models for the development of digital competencies of modern civil servants.The purpose is theoretical and applied research of the current state of digital competencies of Russian civil servants.The objectives: to reveal the theoretical aspects of digital competencies of Russian civil servants (their definitions, models); to conduct a study in the format of professional self-testing aimed at establishing the level of development/non-development of digital competencies by Russian civil servants; to give recommendations on improving digital competencies.Methodology. In the course of the research, theoretical research methods were used: analysis, synthesis, deduction, induction, idealization, analogy, formalization, modeling; special research methods: traditional analysis of documents on the topic of digital competencies of civil servants, self-testing of Russian civil servants, as well as a systematic approach and assessment of the regulatory framework in the field of competencies in the civil service Of the Russian Federation.Results. Based on the data of self-testing of civil servants, it was revealed that Russian civil servants have a certain basic set of competencies in the field of information and communication technologies (ICT), but do not possess digital competencies focused on the development and implementation of modern "end-to-end" digital technologies in the public sphere.Conclusions. To strengthen the digital preparedness of civil servants, it is necessary to develop mechanisms, algorithms, technologies for the formation and development of digital competencies that are uniform for all civil servants. Civil servants will be able to orient themselves and draw up certain ways to improve their personal, professional and official level with the help of practice-oriented activities aimed at adapting to the conditions of digital transformation of public administration.
The article considers the key aspects of creation of the new global information society problem, connected with modes of mass supervision in information-communication networks.
A technique has been designed for measuring planar components of stray fields from ferromagnetic samples placed in a constant magnetizing field. The technique is based on recording the field of magnetization reversal of a thin magnetic film with the small coercive force being the sensor device of a microwave detector. The possibility of measuring the deformation inhomogeneities caused by mechanical treatment when manufacturing products from ferromagnetic materials is demonstrated. The results of the magnetic measurements agree with the data from X-ray diffraction analysis.
