    • AUGMENTED REALITY AND CYBER CHALLENGES EXPLORATION

      pg(s) 11-13

      Digital environment progress towards real and virtual realities mixing is reasonably producing new understandings for ICT progress expectations. In todays’ mobile web world, augmented realities are practically integrating ‘Internet of Things’ (IoT) mobile concept and 3D visualization technologies into a new evolving smart world. This changes our everyday life concepts, adding capabilities with innovative functionalities. However, it also is generating multiple challenges from cybersecurity perspective. This paper studies the problem for human-machine interaction, accentuating on the multifaceted understanding of possible threat sources and attack vectors in the new augmented reality research area. In this context, a system model with prognostic analysis is proposed. The necessity of obtained results validation is finally discussed.

    • DESIGN OF CONTROL SYSTEM WITH INCREASED POTENTIAL OF ROBUST STABILITY FOR NONLINEAR OBJECT USING LYAPUNOV FUNCTION

      pg(s) 17-20

      The article considers approach to construction of control system with increased potential of robust stability of spacecraft in the class of three-parametric structurally stable mappings. Since modern control systems are developed and operated in conditions of significant uncertainty, increasing the potential of system’s robust stability is one of the key factors that guarantee the system of protection against the generation of deterministic chaos and instability. In this regard, in conditions of great uncertainty, to build a control system with rather wide area of robust stability is proposed a method for constructing Lyapunov functions based on the geometric interpretation of Lyapunov’s theorems on asymptotic stability and dynamic systems stability concepts.

    • JUMP MATH AND THE RISK MANAGEMENT OF EDUCATION

      pg(s) 21-23

      In this article we discuss the success of the program JUMP MATH in primary and secondary school in search for a system of teaching that produces similar results in all school levels of mathematics and possibly in the sciences. We view the program from risk management point of view and from algorithmic perspective. We propose a general frame of teaching mathematics that can be applied from schools to university level with great economic effect if the results are similar like the results of JUMP MATH.

    • EXPLOITATION RESULTS OF MANAGEMENT INFORMATION SYSTEM FOR MEDICAL PERSONNEL IN THE MILITARY MEDICAL ACADEMY, SOFIA, BULGARIA

      pg(s) 24-26

      An Administrative Information System (AIS) by definition includes digitized systems supporting storage, retrieval, processing and maintaining information in support of administrative services in one unit, regardless of its profile. AIS, operating within the health establishment, does not include document that is directly related to medical and health information, nor with patient data and records. The urgent need to develop application for administrative management of medical staff in MMA, stemmed from the fact that the institution has a number of components of an integrated information system in conformity with Bulgarian standards of medical care, which covers 90% of the activities in the hospital, however, it serves mainly medical and health activities and the related documentation, but not the administrative part.

      The introduced in production three years ago solution is developed according to the following standards: ISO 13606-4: 2008, ISO / TS 21547: 2010, ISO 18308: 2011, ISO 27789: 2013 and ISO / IEC 15408-2, performs author`s system internally administrative services, satisfying the requirement to communicate to different users working in conditions ranging medical and non-medical legislation and statutory regulations. The goals that were put in implementation, on the one hand include requirements to facilitate the work of medical secretaries who are mainly responsible for the preparation of many administrative documents, on the other – to reduce and minimize the time consumption, consumables and labor, which itself actually lightens the organization of the document in MMA as a whole. The article presents a large-scale survey among staff of MMA on satisfaction of using the system, and analyzes and slices based on service period.

    • THE IDEA OF THE TECHNICAL PROGRESS AND THE POLITICAL ECONOMISTS (18TH AND 19THCENTURY)

      pg(s) 27-30

      If we assume the definition of political economy as a science responsible for the distribution of resources and goods in society, we will find a fundamental reason and a motive to be interested in the issue of technical progress. We will consider technical progress as a social, economic and political phenomenon that is at the heart of many debates on behalf of “optimistic” political economists and others who have a more “pessimistic” vision. Our study is based on the attitude of some of the most famous political economists from the period of the 18th and 19th century during which political economy gets institutionalized and the industry develops revolutionary.

    • DEVELOPMENT OF COMPUTATIONAL TECHNIQUES TO SOLVE PROBLEMS EXTERNAL AND INTERNAL BALLISTICS

      pg(s) 3-6

      The paper is dedicated to the improvement of existing and development of new mathematical methods for ballistics. We consider the interpolation of air drag function by using parabolic spline. Used spline does not require any additional conditions and is stablе. The efficiency of the application of parabolic spline for different drag functions is shown. The spline approximation demonstates good accuracy, saves the behavior of drag functions and can be used in models of external ballistics. The Dirichlet boundary value problem for the unsteady-state equation of convection-diffusion-reaction with the prevailing convection are presented too. For differencing is used the parabolic spline that is continuous together with its first-order derivative which does not demand any additional conditions for its construction. Search for solution of the task in the form of a spline is applied to time-discretizable equation of convection-diffusion-reaction. For the received of difference scheme its monotonicity is proved. Theoretical researches and results of numerous experiments show that the offered scheme for the equation of convection-diffusion-reaction allows to solve boundary value problem for the wide range of values of the equation coefficients. This applies especially cases when convection far exceeds diffusion. The monotonic scheme provides stability of the computational solution, and application of a parabolic spline for its construction allows to reproduce the solution in the form of continuous function for the timepoints determined by discretization. There are given examples of calculations for a case of domination of the convective term over diffusion one.

    • THE DEVELOPMENT OF THE TELECOMMUNICATIONS MARKET IN BULGARIA

      pg(s) 31-32

      ICT is a very dynamic sector, developing at a rapid pace in the recent years. The development of technology enhances the ability of the operators to provide new and better services, at constant price reduction of the services. Nevertheless, the total volume of the electronic communications market in 2014 constituted 3.1% of the total GDP (Gross domestic product) of Bulgaria.

      In the state there is a steady trend of increasing the share of the mobile services compared to the fixed services. Mobile voice services have a leading role in the development of the electronic communications market. With the development of broadband technology, although at a slower pace is increasing the penetration of the fixed broadband access. Services for data and / or internet access are on third place by importance in the telecommunications market.

    • LEGAL FRAMEWORK FOR THE PROTECTION OF CBRN AGENTS IN BOSNIA AND HERZEGOVINA

      pg(s) 33-36

      In this paper the authors present legal framework for the protection against CBRN agents in Bosnia and Herzegovina. By critical analyzing existing legal framework the authors will determine plausible legal course of action in cases of danger caused by CBRN agents. Namely, although use of CBRN agents for industrial purposes is thoroughly regulated the may be abused in the various activities against civil society. The may be abused through the acts of terrorism and sabotage and misused through inadequate handling of the agents and their byproducts. The final goal of this paper is to examine the applicable value of the existing legislation in this area in Bosnia and Herzegovina.

    • EXAMPLE OF SECURITY MANAGEMENT SYSTEM OF THE ORGANIZATION – COMPONENTS AND CONCEPTS

      pg(s) 37-40

      Issues related to security are intertwined in all areas of the life of an organization. Many of them are considered and documented organizational and provided within the respective area/subsystem of the management system of the organization. For example, information security management is detailed and reliably described in the international standards. And this is natural, considering the importance of this type of security and the fact that information technology lie at the core of almost all organizations. In the meantime however, it is necessary to go a long way to reach the ultimate goal of improving security of the organizations by developing integrated management systems for business security. A Security Management System may be considered as that part of the overall management system, based manly of the quality management system, that provides the structure to enable identification of potential threats to an organization and which establishes, implements, operates, monitors, reviews and maintains all appropriate measures to provide assurance of the effective management of the associated security risks.

    • ETHNICITY, RELIGION, NATIONAL IDENTITY

      pg(s) 43-45

      The processes we designate as globalization tend to provoke resistance, which arises ever more often as an effort on the part of various ethno-cultural and religious traditions to preserve their own identity. In this context, ethnic and religious affiliations become centers of meaning in the striving towards a separate identity in the global debate regarding the quality of human development.

      Achieving a national community and building new norms of coexistence under the conditions of ethno-religious variety are becoming a strategic goal of contemporary development. Contemporary civilization faces the need to respond to the critique and resistance of various forms of religious fundamentalism, and especially the critique formulated in the tradition of Islamic fundamentalism.

      The problems related to national identity have been far more often described and discussed in the context of nationalist fears of difference than in terms of the effort to overcome the crisis of identity amidst the imposed similarities. Under Bulgarian conditions, ethnic and religious diversity continues to be perceived as an established fact that we must take into account, and not as a resource for nation building. Achieving a national identity should be the result of joint effort. The first and most difficult part of this effort is to recognize that this common meaning exists in a diversity of forms. The coming years will be marked by a search for new grounds of one’s own identity, a search for the spaces that define parts of ourselves. The great challenge facing Bulgaria is to rediscover the values and meaning of the national community. Only thus will our genuine, full presence in Europe become a fact.

    • PEOPLE USE EMBODIED REPRESENTATIONS NEVERTHLESS THEY MAY USE DIFERENRT STRATEGIES IN PROBLEM SOLVING

      pg(s) 46-49

      In their classical study, Sheppard and Metzler (1971) demonstrated that the speed of mental rotation of objects is linearly proportional to the angle that the objects should be rotated. However, Flusberg & Boroditsky, (2011) assume that depending on the instruction distinct processes take part in mental rotation task. The results of their empirical study usually are interpreted in favor of necessity to assume that dual processes (and hence dual representations) exist in human cognitive system. We conducted an experiment that confirms the hypothesis that different strategies, not different processes underlie the results of Flusberg & Boroditsky, (2011).

      Nevertheless that the topic may seem too specialized, it supports the embodied view to human cognition. In this way, the findings have not only theoretical merits, but can be of high interest for education planning. Studying the effects of the body on the mind contributes the education planning and has an increasing role in mathematics education and problem solving issues in high school, college and beyond.
