PHILOSOPHICAL REASONING OF THE CONCEPT OF THE GAME AND ITS USAGE IN NONPLAYING CONTEXT
DescriptionIt is interesting for interdisciplinary understanding of game phenomena, how the concept of the game discourse can operate in different nonplaying contexts. Researching of game concept allows tracing the figurative conceptualization knowledge of this universal phenomenon. The author uses a lot of examples to prove that game phenomenon represents itself in a language and has been reflected in the mind of people. It is shown, that lingvoculturological concept of the game has more productive metaphorical rethinking. We single out the most important characteristics of game, explain some imaginations about gaming, explicate dominant sense of game freedom, its choice, imitation, dynamic and emotional stress, agonistic, risk, unpredictability and others attribute the symptoms. Represented contexts of usage also illustrate communicative and social components of gaming behavior. Dominant meanings, key ideas, that unite viewed image, actualize basic principles that are typical for the game phenomenon in common, and the specific characteristics of different types of games (sport, children, gambling, theater, computer, etc.)

THE INFLUENCE OF THE CURRENCIES RATE ON THE COUNTRY’S ECONOMICS
DescriptionThe main aspects of the financial market influencing the country’s economy are considered in the article. In this field certain historical facts connected with the financial market are outlined. These facts show the USA economy influence on the world’s economics space determining the countries’ ability to resist financial expansion and insure their economies securities. Sustainable economic system capable to reserve the country’s sovereignty and to resist outer economic and political pressure is required for this activity. The basic aspects of the world currency system are given, the essence of some of them is revealed, some proposals are made that could stabilize the economies of the dollardependent countries. Besides, the article highlights the necessity to own gold reserve which means some extent secures to the country’s sovereignty. The agriculture investing perspective in case of inflation rate alignment is highlighted. The factors that influence the rate of the currency are given. Competitive ability of domestic products that have great influence on the country’s foreign trade is pointed out as the main factor in the relevance of the topic. To confirm some ideas of the article the opinions of scholars, known throughout the world as economists and philosophers are given. The topic of the welfare of the citizens of the country in periods of currency fluctuations has been considered and the recommendations for the improvement of their own position have been made

THREETIER CLIENTSERVER INFORMATION SYSTEM OF CONFIGURING DATABASES
DescriptionCurrently, the problem of using a "clientserver" technology for database is uptodate. Among its advantages it has a high degree of security, the ability to work with multimedia and nonstandard data, simple tastes to the hardware power client stations, the territorial independence of work in both local and wide area networks. The article presents the concept and describes the implementation of a clientserver information system configuration databases based on plugins that enable flexible, fast and efficient to make changes to an existing application for working with databases. This approach solves the problem of using one program to connect to multiple databases

SOIL DEGRADATION AND THE ROLE OF FOREST BELTS IN LAND MELIORATION
DescriptionSoil degradation (erodere – eat away, lat.)  a process when pieces of rocks and soil are separated from their initial location. Then transferred and deposited in some new place. The factors of erosion are water, wind, landslides, rock particles and etc. Erosion is the process of destruction and demolition of the soil cover (or parent rocks) by flows of water or wind which causes depletion of fertile top soil layer. The destruction of this layer occurs quickly, and for its restoration thousand years are required. Reduction of soil fertility is one of the main problems that are associated with its pollution. Erosion is a natural process that occurs very slowly ever since the Earth was formed (about 4550 billion years ago). Realistically, mountains, valleys, plains and deltas on the Earth's surface have been created by water and wind erosion as a result of their joint action over a long period of time. Geological erosion was acted at a slow pace for hundreds of years. When humans appeared it occurred to be an invasion of species which could transform their natural environment. An artificial type of erosion, which acts much faster than the natural erosion, was formed because of human

DescriptionIn the article the application of systemiccognitive analysis, its mathematical model  the system theory of the information and its program toolkit  "Eidos" system for synthesis of the generalized images of classes, their abstraction, classification of the generalized images (clusters and constructs) comparisons of concrete images with the generalized images (identification) are examined. We suggest a new approach to the digitization of images, based on the use of the polar coordinate system, the center of gravity of the image and its contour. Before digitizing images we can use their changes to standardize the position of the pictureframes, their size and rotation. Therefore, if you specify this option, the results of digitization and image ASCanalysis can be invariant (independent) to their position, size and rotation. This means that in the model on the basis of a number of specific examples we will create one image of each class of images, independent of their specific implementations, i.e., the "Eidos" of these images (in the sense of Plato)  a prototype or archetype (in the Jungian sense) images. But the "Eidos" system provides not only the formation of prototype images, which quantitatively reflects the amount of information in the image elements of the prototype, but the removal of all irrelevant to identification (abstraction), and the comparison of specific images with generic (identification) and the generalized images of images together (classification). The article provides a detailed numerical example of ASC analysis of images

DescriptionFollowing the absence of a definite treatment for the human immunodeficiency virus (HIV) or the acquired immune deficiency syndromes (AIDS) since their appearance, many scientific studies with the help of mathematical models have been formulated to the extent possible to prevent and eradicate the disease. In this article we have formulated a mathematical model that explores the dynamics of the impact of the use of condom and therapeutic treatment simultaneously, as a means (tools) against the spread of HIV/AIDS in the heterosexual population. The proposed model uses a nonlinear differential equation system consisting of seven (7) differential equations in seven (7) groups of the population. The model takes into account natural birth rate of the studied population, and the proportion of infected males, which simultaneously uses condom and antiretroviral therapy. The model explores the behavioral change of proportion of infected individuals in the population following the application of control measures (condom use and antiretroviral therapy). It is proved that the effectiveness of preventive measures greatly depends on a number of parameters described. In addition, the results of numerical experiments showed that in the absence of both preventive measures, the entire population is contaminated with the infection. The interaction of the model parameters show that the population with high levels of condom use in the presence of significant adherence to antiretroviral therapy as prophylaxis significantly reduces the level of HIV/AIDS. Thus, prevention of infection is significantly improved with the increasing number of the infected population using condoms and antiretroviral therapy simultaneously

BASIC RESULTS OF THE MATHEMATICAL THEORY OF CLASSIFICATION
01.00.00 Physicalmathematical sciences
DescriptionThe mathematical theory of classification contains a large number of approaches, models, methods, algorithms. This theory is very diverse. We distinguish three basic results in it  the best method of diagnosis (discriminant analysis), an adequate indicator of the quality of discriminant analysis algorithm, the statement about stopping after a finite number of steps iterative algorithms of cluster analysis. Namely, on the basis of Neyman  Pearson Lemma we have shown that the optimal method of diagnosis exists and can be expressed through probability densities corresponding to the classes. If the densities are unknown, one should use nonparametric estimators of training samples. Often, we use the quality indicator of diagnostic algorithm as "the probability (or share) the correct classification (diagnosis)"  the more the figure is the better algorithm is. It is shown that widespread use of this indicator is unreasonable, and we have offered the other  "predictive power", obtained by the conversion in the model of linear discriminant analysis. A stop after a finite number of steps of iterative algorithms of cluster analysis method is demonstrated by the example of kmeans. In our opinion, these results are fundamental to the theory of classification and every specialist should be familiar with them for developing and applying the theory of classification

DescriptionIn the article we have derived mathematical models of nonstationary transport binary electrolyte in EMS (electromembrane systems: electrodialysis apparatus, electromembrane cell, etc.) for the galvanostatic mode. To be specific, as EMS viewed channel of desalting of EDA (electrodialysis apparatus) and EMS with RMD (rotating membrane disk). We present a formula expressing the intensity of the electric field through the current density and concentration. Also, we have received the differential equation for the current density. The fundamental point here is derived new equation for the unknown vector function of current density of the initial system of equations of NernstPlanck. In addition, the article shows the output equation for the current density in three dimensions; we have proposed various methods for solving the equation of the current density and the boundary conditions for the current density. The proposed mathematical models of transport binary electrolyte are easy to be generalized to an arbitrary electrolyte. However, the corresponding equations are cumbersome. It should be also noted that the boundary conditions can be varied and depend on the purpose of a particular study in this regard, in this work are just the equation having the general form

Description
The calculation of pumping equipment and piping network parameters is presented. The method of cutting impeller pump diameter for optimal performance of pump unit with piping system on efficiency value is shown. The case of operating the distribution network and pumping station with three pump units D125025 is considered. Procedure of construction of lossofhead curves in pipes, determination of the actual operating parameters of a single pump unit, selection of pump impeller diameter for essentials is indicated. Four points for graphing such curves are presented. According to the first point the whole network is divided into sections with suction, pressure main pipelines and pipelines with changing water flow compared with the previous ones. The second point involves definition of the electrical resistivity of each site. The resistance of network analyzer is determined in the third point, the lossof head of the whole network is determined in the fourth point. The article presents the scheme of pumping station with three pump units connected in parallel and a distribution network (Figure1), lossofhead curves in pipes regardless the number of working pumps (Figure 2), the order of constructing three lossofhead curves with operating one, two and three pumps with normal and cut pump impeller diameter (Figure 3 ), the order of determination of the actual parameters of pump work characteristics according to combined characteristics of normal and cut pump impeller diameter ( Figure 4) In conclusion, it is stated that the question of proper definition of actual parameters of pumps and the support of these parameters in optimal mode remains open due to the lack of proper methods of constructing lossofhead curves pipeline. Every similar calculation is preliminary and should be carried out in field conditions
