Концептуальна модель дистинктивної поведінки особистості

B a c k g r o u n d . Modern society is characterized by a variety of individual characteristics manifested in a person's behavior. Distinctiveness is a type of behavior described by non-stereotypical actions, a person's tendency to manifest individuality, and the desire to be socially visible, aiming to create an impression and gain the attention of others. Objective. To develop and disclose a conceptual model of the distinctive behavior of personality. M e t h o d s . Euler-Venn diagrams were used to graphically represent the relationship between distinctive behavior and norms in a particular subject area. R e s u l t s . Two functional dependencies for social and personal factors influencing distinctive behavior are proposed. The concept of "norms", defined from the "angle of view" of the subject area in which a particular norm was formed, is introduced. Two functional dependencies for social and personal factors influencing distinctive behavior are formulated. The concept of norms defined from the "angle of view" of the subject area R is introduced. At the social system level, the forms of distinctiveness manifestation are hypothetically divided. The theory of optimal distinctiveness is considered. The proposed classification of behavioral signs of individual distinctiveness as an element of the social system is divided into three groups, and the main components of each group are highlighted. C o n c l u s i o n s . Through theoretical analysis of the scientific literature, it was determined that distinctive behavior can be described as a type of personality behavior based on the desire to express identity while overcoming the social norms that have developed in a certain reference group in the current period.

КОНЦЕПТУАЛЬНА МОДЕЛЬ БЕЗПЕКИ КІБЕРПРОСТОРУ

Urgency of the research. Public information resources and means of electronic network transactions (servers, routers, remote access servers, communication channels, operating systems, databases and applications) must be protected reliably and efficiently: the price of each "break" of protection is growing rapidly and this growth will continue in the near future.Target setting. Ensuring information security of networks and processing systems is a priority for the state leadership, as the quality and efficiency of strategic decision-making and the effectiveness of their implementation largelydepend on main-taining the confidentiality, integrity and availability of state information resources.Actual scientific researches and issues analysis. Despite the ever-increasing number of publications on information se-curity, the problem of security in cyberspace, especially a state one, remains unresolved.Uninvestigated parts of general matters defining. Currently, in the works of domestic and foreign scientists, insufficient attention is paid to the development of systems and models of cybersecurity of the state.The research objective. The aim of the article is to build a conceptual model of security within cyberspace, which will describe the components of national cybersecurity and will establish the strength of the connection between its relevant com-ponents, as well as determine the level of cybersecurity.The statement of basic materials. Using Euler-Venn diagrams, the cyberspace of the state is graphically represented and a more rigorous description of the model is proposed on the basis of set theory. In general, the conceptual model of cyberse-curity is formed on the basis of three components: a person who processes information, owns it or protects it; regulations that provide legal protection of information; information resources, where the information in need of protection is concentrated, and within which means of information protection function.Conclusions. The article builds a conceptual model of state security, which describes the components of cybersecurity of the state and allows to establish the strength of the connection between its relevant components, as well as to determine the level of cybersecurity.

Plotting Ternary Diagrams by R Library ggtern for Geological Modelling

Selecting proper methods of data modelling is crucial in geosciences, as effective data visualization enables better understanding of complex geological phenomena: processes, structure and dynamics. Various approaches of the data analysis by R language include both traditional methods of linear charts and other approaches to data visualization: ternaries, circular and radar charts. Using ternaries for triple correlations between variable can be seen in applied geological analysis which proves it to be important method for data modelling. Visualizing geological variables by ternaries enables to highlight correlation between variables in a triangle, how data are dependent and affected. In this study, several geologic, tectonic and geomorphic variables, such as sediment thickness, tectonic plates, volcanic areas, steepness and depths, were tested using R based modelling in {ggtern} library. Other graphs include radar charts and circular diagrams. Visualizing attributes as a triple component correlation by ternaries gives a better insight to the geological factors. Traditional techniques for visualization of pairwise linear correlations are not sufficient to show triple variations. Ternaries approach identifies data correlations by triple factors. Additional graphical models include circular and Euler-Venn diagrams of quantitative and qualitative geospatial data modelling. The study is supported by 7 R code listings and 9 figures.

Flexible Discrete Math offline Test Generator

This article describes the software package representing new math tests generator.The main features of our software are in the focus on creating a high-quality printed product and large variability of the generated tasks. That were achieved by using the LaTeX~text processor and power of the Python language. Logically it consists of the control shell, the task parser, subject logic, formatting system and task database. The logic implements the set of abstractions that can be used in tasks (for example graphs, boolean functions, etc.). The task database exists in the form of JSON files with the specially created task formation language.Currently, the most developed branch in task database is the discrete mathematics problems and abstractions. More than fifty types of tasks were implemented: operations on sets, representation of sets by Euler-Venn diagrams, algebra of sets, various ways of representing graphs, operations on graphs, some problems on graphs, representing Boolean functions in various ways, finding perfect forms, constructing and minimization using Karnaugh maps, Venn diagrams and hypercubes, analysis and synthesis of logic circuits.The task generator can be used by a teacher when conducting practical and control classes, creating individual materials for the students. Tasks can be differentiated by the level of complexity when changing control parameters.The generated tasks were used in education process for more than 1000 students of Military Academy of the Signal Corps and the improvement of mastering of discrete math was shown.

Studies on populations of Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae: Phlebotominae) in Brazil.

Studies were performed on five Brazilian populations of Lutzomyia longipalpis: Salvaterra (PA), São José do Ribamar (MA), Canindé (CE), Natal (RN) and Gruta da Lapinha, Lagoa Santa (MG). No morphological differences were observed that could distinguish between these populations. Homogeneity tests showed that the allopatric populations display a certain heterogeneity and that the sympatric populations, with different patterns of spots, are homogeneous. The Student-Newman-Keuls test, represented by Euler-Venn diagrams, showed a disjunction between the populations from the north/northeast and the one from Gruta da Lapinha. Genetic distances between the four populations (excluding the Canindé population) were within the range of intrapopulational differences. The Gruta da Lapinha population displayed a heterozygotic deficiency that could be a consequence of high levels of inbreeding due to cryptic habits of living in a small cave. These results do not favor the hypothesis of a L. longipalpis species complex in Brazil, and the species should be considered high polymorphic.
