The role of healthy lifestyle in strengthening pupils` health – the basics of human life-sustaining activity
Annotation:

This article mainly deals with the role of healthy lifestyle in strengthening pupils` health. The relevance of the issue of healthy lifestyle modeling arises out of the fact that heath is one of the most significant life values of a person and a guarantee of his or her welfare longevity. Currently, due to the low life expectancy of people, it is crucial to foster the meaning of health as the main value in one`s life and importance and necessity of health preservation from the early childhood. Life preservation requires dedicated and persistent efforts from every person. Herewith, it is necessary to understand one fact: life preservation is a personal prerogative. If one is to always be healthy one must remember that it requires persistent, dedicated and considerable efforts. Therefore, it is crucial to have a long course of personal conduct that designates the general culture of our labour and rest management, rational combination of physical and mental workload, sensible nutrition, active leisure and good quality sleep, and, moreover, skills of safe conduct in different dangerous emergencies. All of it composes the system of healthy lifestyle.

Extraction of non-ferrous metals from dusts of converter steel-melting production
Annotation:

In the article presents the results of studies on the effect of temperature and pressure on the chloride sublimation of zinc and lead from converter dusts of steel production. Currently, an objective necessity is the development of dust utilization technologies for converter steel production, with its further use in production and production of by-products. The use of dust allows not only to save natural raw materials, but also increases production efficiency and improves the environmental situation. The content of non-ferrous metals in dusts makes it difficult to process and use them in agglomeration or in blast furnace production, while the iron content in converter dusts (sludges) makes it possible to use them as promising metallurgical raw materials. Therefore, for a more complete processing of dusts, extraction of non-ferrous metals from them is proposed. The purpose of this work was to determine the possibility of extracting zinc and lead from sludges of the converter production by the method of chloride sublimation. We used dust containing: 86,3 % Fe2O3, 3,5 % FeO, 0,9 % Al2O3, 1,6 % CaO, 0,9 % MgO, 1,1 % MnO, 0,8 % SiO2, 4,4 % ZnO, 0,5 % PbO. The study was conducted in the temperature range 200-1600 degrees C and pressures of 0,01; 0,1 and 1 bar based on a complete thermodynamic analysis using the HSC – 5.1 software package. Finnish metallurgical company Outokumpu, based on the principle of minimum Gibbs energy. According to the results of the studies, it was found that, at normal pressure, lead chloride sublimationbegins at a temperature of 600 degrees С, and zinc - at 900 degrees С: a decrease in pressure to 0,01 bar reduces the temperature to 500 degrees С and 700 degrees С, respectively; lead chloride sublimation under equal conditions is more complete than zinc; To achieve zinc chloride distillation at the level of 90-96 %, the process must be carried out at 1145-1200 degrees С and pressure from logP = -2 to 1,2 bar, while the degree of lead chloride distillation is 99,8-100 %.

Simulation of property management using the example of filling station chain
Annotation:

When managing a filling station chain, it is necessary to solve the following tasks in dynamics: determining the volume of purchases by types of oil products sold and redistributing the available volume of various types of oil products to filling station chain. The peculiarity of this control task is that the replenishment of the storage of oil products is carried out centrally, and the sale of each type of fuel is carried out at separate filling stations of the network, that is, in many points. At the same time, the volume of each type of fuel sold by each station of the network should be taken into account separately, taking into account the seasonal demand for a specific oil product. In addition to modeling demand, information is needed on the volume of petroleum products that can be purchased from suppliers with the possibility of increasing or decreasing the volume of purchases due to demand. To solve this problem, a list of suppliers of a specific type of oil product with a possible range of supply volumes must be determined. In the proposed model, an attempt is made to solve the above problems. To solve them, a management model was developed, which was implemented using the Visual Studio C # programming environment and MS SQLServer DBMS. When developing the structure of the database tables, the task of managing a network of filling stations based on the Petri net was taken into account: that is, the database tables provided for storing information on the volumes of supplies of petroleum products, the volume of sales of each type of petroleum product, as well as the time of deliveries and sales. To solve the problem of centralized procurement for all types of fuel, the database provided tables with information about suppliers and possible volumes of supplies by them of various types of petroleum products. To solve the problems of forecasting demand, the model includes algorithms for predicting the volume of sales of petroleum products based on the accumulated time series of data for each type of fuel separately. The forecasting was carried out in order to assess the required volumes of purchases of oil products for the coming period. The prediction algorithms are implemented using two methods: linear approximation and exponential smoothing. Both algorithms take into account the seasonality of demand.

Mathematical modeling of the results of experimental studies of the influence of the type and dose of cheese melting salt on the qualitative indicators of melted cheeses
Annotation:

The article is devoted to the mathematical modulation of a complex of experimental data obtained in the process of experimental studies of processed cheese products, processed by mathematical methods. The purpose of this study is to establish the type and amount of the melting salt that promotes the formation of the plastic structure of the processed cheese product. The analysis of scientific research in the field of food technologies showed that mathematical modeling is used in the following areas: clarification of the modes of technological processes, design of recipes and assessment of the quality of finished products, as well as forecasting the shelf life of new products when they are put into production. The most relevant in describing the processes of food production are models of multivariate variance-regression analysis using methods of mathematical planning of the experiment. The authors carried out mathematical modeling and established graphical dependencies characterizing the degree of influence of the regulated factors X1 and X2 on the controlled ones that determine the quality and safety of processed cheese products. It is important that the mathematical analysis of the graphical dependences of the rheological parameters on the adjustable factors indicates the reliability of the data obtained. It is concluded that an increase in the melting salt dose leads to an increase in the – limit shear stress, which reflects the nature and state of the consistency of the processed cheese product. The process of normalization of the controlled factors by the maximum value was carried out. Graphical dependencies were built and regression analysis was performed, the results of which allow an objective assessment of the degree of influence of the type and dose of the melting salt on the chemical and organoleptic characteristics of the test products. The authors have proven that the optimal efficiency of transforming the structure of the constituent components of the recipe into a plastic structure of a processed cheese product that is stable during storage is provided by a combination of adjustable factors X1 (Solva 85) and X2 (Solva 120) taken in a ratio of 1: 1, with a total amount of 1,2 mas.%. At the same time, the quality indicators of the experimental products are characterized by the following values of the controlled factors: У1 – 1280 Pa; У2 – 9 points, У3 – 9,301 (2,0-2,2109 colony forming units /g).

Method for hiding text data in an image
Annotation:

The main problem: The article deals with the issues of hiding text information in a graphic file. A formula for hiding text information in image pixels is proposed. A steganography scheme for embedding secret text in random image pixels has been developed. Random bytes are pre-embedded in each row of pixels in the source image. As a result of the operations performed, a key image is obtained. The text codes are embedded in random bytes of pixels of a given RGB channel. To form a secret message, the characters of the ASCII code table are used. Demo encryption and decryption programs have been developed in the Python 3.5.2 programming language. A graphic file is used as the decryption key. Purpose: To develop an algorithm for embedding text information in random pixels of an image. Methods: Among the methods of hiding information in graphic images, the LSB method of hiding information is widely used, in which the lower bits in the image bytes responsible for color encoding are replaced by the bits of the secret message. Analysis of methods of hiding information in graphic files and modeling of algorithms showed an increase in the level of protection of hidden information from detection. Results and their significance: Using the proposed steganography scheme and the algorithm for embedding bytes of a secret message in a graphic file, protection against detection of hidden information is significantly increased. The advantage of this steganography scheme is that for decryption, a key image is used, in which random bytes are pre-embedded. In addition, the entire pixel bits of the container image are used to display the color shades. It can also be noted that the developed steganography scheme allows not only to transmit secret information, but also to add digital fingerprints or hidden tags to the image.

Some aspects of justification of acceptable risk levels in oil refineries
Annotation:

Currently, the problems of environmental safety are facing society. The industry develops every year. In this critical economic situation, the oil industry is a stimulant for the economic sector in Azerbaijan. The level of development of this industry is also relevant due to other reasons: sociological, technological and features of the economy of Azerbaijan. The production activity of oil processing, concentrating harmful substances and energy, is a source of man-made danger and pollution of the natural environment. The risk management process mainly consists of three stages - risk safety analysis, risk assessment, which is carried out in comparison of calculated and actual risk levels, the so-called acceptable risk levels and the adoption of appropriate regulations and management decisions. One of the factors that should be taken into account when assessing risk and safety is to determine the necessary costs. Since these costs are paid directly to the company, they try to minimize them as much as possible, which reduce the accuracy of risk assessment. One of the objectives of the study is to determine the optimal value of the necessary costs. It is established that the less reliable the method, the lower is the cost of its implementation. The methodological basis of the work was scientific works on these problems of scientists-economists, mathematicians on safety and risk assessment at industrial enterprises. When developing the presented methodology, computational algorithms developed by Dow Chemical were used. This company has collected a large volume of material on accident statistics, taking into account damages. Based on the obtained and experimentally verified data, a system of indices has been developed, an assessment of various indicators for qualitative and quantitative risk assessment of oil refineries. The analysis of the technogenic danger of oil refineries makes it possible to determine ecological and economic losses and choose rational possibilities of acceptable risk. The required costs, depending on the level of risk, are determined based on an increase in the accuracy of calculating the probability of occurrence of the cause of risks. The article examines the relationship between the expected level of risk and economic losses during oil refining in separate technological units, which allow determining the required level of risk and the expected economic damage.

Ingularly perturbed equations in critical cases
Annotation:

Singularly perturbed partial differential equations with small parameters with higher derivatives deserve special attention, which often arise in a variety of applied problems and are used in describing mathematical models of diffusion processes, absorption taking into account small diffusion, filtration of liquids in porous media, chemical kinetics, chromatography, heat and mass transfer, hydrodynamics and many other fields. It is necessary to consider the creation of an asymptotic classification of solutions of singularly perturbed equations using a well-known approach to solving the boundary value problem. In this case, the singular problem is understood as the problem of constructing the asymptotics of the solution of the Cauchy problem for a system of ordinary differential equations with a small parameter with a large derivative. The asymptotics of the solution in all cases is based on the last time interval or the construction of a boundary value problem for a system with a weak clot in an asymptotically large time interval. Purpose - to construct and substantiate the asymptotics of solving a singular initial problem for a system of two nonlinear ordinary differential equations with a small parameter; To date, a number of methods have been developed for constructing asymptotic expansions of solutions to various problems. This is the method of boundary functions developed in the works of A.B. Vasilyeva, M.I. Vishik, L.A. Lusternik, V.F. Butuzov; the regularization method of S. A. Lomov, methods of averaging, VKB, splicing of asymptotic decompositions of A.M. Ilyin and others. All the above methods allow us to obtain asymptotic expansions of solutions for wide classes of equations. At the same time, such singularly perturbed problems often arise, to which ready-made methods are not applicable or do not allow to obtain an effective result. Therefore, the development of methods for solving equations remains a very urgent problem. As a result of the study, an algorithm for constructing an asymptotic classification of the initial solution of the problem with a singular perturbation is given, and approaches to estimating the residual term are also shown.

The possibility of using correlation and regression analysis in ecological and economic research at oil refineries
Annotation:

It is known that an increase in the volume of production in any sphere of production as a consequence increases the intensity of anthropogenic impact on the environment, including the atmosphere. This problem is especially typical for oil refineries. On the one hand, this is due to the complexity of oil refining processes and the release of various hydrocarbon compounds into the atmosphere during processing. Therefore, when implementing sustainable ecological and economic development in the Azerbaijani regions that are associated with oil refining, an increase in the volume of products should not create an increase in environmental impact. This problem is considered one of the factors directly affecting the economic situation of the enterprise, as well as creating certain environmental, social and economic problems for society as a whole. The purpose is to study the possibility of using the correlation-regression method in solving the problem of determining the presence of the decapling effect. The relationship between the volume of petroleum products produced and the amount of pollutants released into the atmosphere is random and is characterized by stochastic and statistical dependence. At the same time, on the basis of a mutual comparison of the methods of correlation and regression analysis and the method of production function, the effectiveness of correlation and regression analysis is determined. The methodological basis of the work was the scientific works of scientists-economists, mathematicians providing the definition of the decoupling effect at industrial enterprises. In the presented methodology, the obtained estimates of the performed in real time vary depending on the values of the set parameter. When developing the presented methodology, the STATISTIKA software package was used. This program was developed by StatSoft. Based on the obtained and experimentally verified data, the equation of linear regression dependence is determined. During the research, it was found that in some cases it is not possible to evaluate the statistical characteristics of a random variable or it is accompanied by serious errors. Therefore, when processing data, instead of mathematical expectations and variances, we used selective mathematical expectations and variances. The analysis of the ecological and economic situation of oil refineries based on correlation and regression analysis allows us to determine the presence of the decapling effect. The obtained correlation coefficient between the volume of production oil products and the volume of emissions into the atmosphere shows that there is no statistically significant relationship between these parameters. Thus, there is an achievement of the decoupling effect between the production of petroleum products and the volume of emissions of pollutants into the atmosphere.

The role and place of local self-government in modern society
Annotation:

Local self-government bodies are an integral mechanism of the foundation of a democratic state. In the modern system of public relations, one of the most important places is occupied by general economic relations, namely local self-government. Without a developed system of local self-government, legislative and real opportunities, it is very difficult to independently create market-democratic structures to solve economic, social, domestic, cultural and other issues at the local level. Local self-government bodies are a special level of government, which combines two principles: public and state. In the practice of Constitutional and administrative law, it is important to determine the place and nature of local self-government and to establish balanced relations between State authorities and self-government bodies, on the one hand, with local representative offices and structures. The purpose of the article isto study the role and place of local self-government in modern society, to develop practical recommendations on the formation and prospects for the development of local authorities in Kazakhstan. When writing an article, the following methods are used: description, analysis and synthesis, justification, logical modeling, system analysis, etc. When studying the formation of local self-government, as well as the functional management system, the method of structural and analytical analysis was used. The conclusions and recommendations obtained as a result of the conducted research can be used: in the practical activities of maslikhats and akimats of the Republic of Kazakhstan, civil servants; in the process of studying at courses in higher educational institutions, as well as for further general theoretical and applied research.

The place and role of the teacher in the system of activities
Annotation:

The ideas of accelerated disclosure of the spiritual, intellectual and professional potential of a person have always been occupied by scientists and teachers (Ya.A. Komensky, K.D. Ushinsky, V.A. Sukhomlinsky, Ya. Korchak, A.S. Makarenko, A. Kunanbayev, Y. Altynsarin and others). Modern innovative teachers are guided by a personality-oriented approach, the ideas of subject-subject relations, and generational cooperation. Georgian teacher Sh. A. Amonashvili wrote: «humanitarian pedagogy perceives the child by his nature. He sees the infinity of the child, understands his cosmic quality and prepares him for the service of humanity throughout his life. It establishes the personality of the child through the determination of his will and builds pedagogical systems, the procedural of which predetermines love, optimism and high spiritual morality. Humanitarian pedagogical thinking seeks to take on something enormous, and this is the power of educational systems and processes that have arisen in its bowels». In order to realize the value of self-disclosure of innovative abilities of students, ensuring the role of a teacher, it is necessary to recognize the intellectual reflexive mechanism of a person as the main subject of Education. The purpose of the article is to identify innovative methods and models of pedagogical activity for the cultivation of innovative abilities of students, which determine the development of the country. The study used methods such as analysis, generalization, synthesis, modeling of scientific sources.

Creating an intelligent management environment for a powerful load node on the example of the Pavlodar region
Annotation:

The present stage of development of power systems is characterized by the need to increase their intelligence, that is, the formation of an environment capable of solving the problems of effective management of all components included in the power system. One of the features of modern energy systems is an active consumer, that is, a consumer who has the opportunity to optimize the schedule of loading their capacities, planning energy consumption, intellectualization of energy consumption. In addition to the fact that there are digital systems for collecting, processing and presenting information, as well as transmitting this information via the Internet, to solve the most difficult task of managing power systems, it is necessary to develop a large number of models adequate to real processes that can describe the processes taking place in the power system under consideration. The purpose is to develop models capable of adequately describing the interrelated processes occurring in the considered elements of the power system, as well as in the aggregate of related elements; development of methods that allow solving problems of effective control of elements of energy systems on the basis of the proposed intelligent models. To solve the problem of increasing the intelligence of the power system, nonlinear adaptive models of electrical complexes of an energy-intensive enterprise included in the power system were developed on the basis of balance equations and artificial intelligence methods. The production of alumina with the properties of inertia, nonlinearity and closure is chosen as the production under consideration. This type of production was chosen as the most difficult to predict due to the unpredictability of changes in energy consumption during the transition to other modes of its operation, associated, for example, with the receipt of raw materials with a different chemical composition for processing. Static and dynamic models of energy consumption of electrotechnical complexes with continuous inertial nonlinear closed production based on artificial intelligence methods have been developed, which makes it possible to eliminate the need to use long time series of retrospective data. For the considered type of continuous energy-intensive production, dynamic characteristics of energy consumption and technological processes are obtained from the main controlled parameters, which make it possible to predict emergency situations and partly man-made disasters. On the basis of a genetic algorithm, a multiparametric optimization problem of energy management of continuous production has been solved, taking into account technological parameters and cost factors.

The role and place of local self-government in modern society
Annotation:

Main problem: local self-government bodies are an integral mechanism of the foundation of a democratic state. In the modern system of public relations, one of the most important places is occupied by general economic relations, namely local self-government. Without a developed system of local self-government, legislative and real opportunities, it is very difficult to independently create market-democratic structures to solve economic, social, domestic, cultural and other issues at the local level. Local self-government bodies are a special level of government, which combines two principles: public and state. In the practice of Constitutional and administrative law, it is important to determine the place and nature of local self-government and to establish balanced relations between State authorities and self-government bodies, on the one hand, with local representative offices and structures. Purpose: to study the role and place of local self-government in modern society, to develop practical recommendations on the formation and prospects for the development of local authorities in Kazakhstan. Methods: when writing an article, the following methods are used: description, analysis and synthesis, justification, logical modeling, system analysis, etc. When studying the formation of local self-government, as well as the functional management system, the method of structural and analytical analysis was used. The results and their significance: the conclusions and recommendations obtained as a result of the conducted research can be used: in the practical activities of maslikhats and akimats of the Republic of Kazakhstan, civil servants; in the process of studying at courses in higher educational institutions, as well as for further general theoretical and applied research.

On the application of CASE-methodologies at the stage of analysis and design of software tools
Annotation:

Main problem: the globalization of the information sphere has led to a significant increase in the volume of stored and processed information. To increase the processing speed and provide information to the recipient, it is logical to increase the power of the equipment on which the information is processed. But such a path also leads to an increase in financial costs for continuous modernization or complete updating of computer equipment and application software. Purpose: an alternative solution to increasing the capacity of hardware and software may be to optimize the process of organizing data storage, and already at the stage of information analysis. At the initial stages of the task, a huge amount of information is collected and processed, which needs to be classified, to identify essential and non-essential information flows for the information system being developed, etc. The quality of functioning of the developed information system as a whole and its individual modules in particular will depend on how correctly and fully the structuring and systematization of data will be carried out. Methods: modern methodologies of conceptual design of information systems shift the emphasis from software implementation to analysis and modeling of the production environment. The tools used in the process of conceptual modeling allow you to automate the main part of the processes, including the development of program code in the format of templates (patterns), including the preparation of documentation for the software product being developed. Since modern methodologies and tools are based on the use of powerful graphical tools, this significantly increases the visibility and simplifies the process of making adjustments to the information system project, actually using the "Drag-and-Drop" technology. This allows you to redistribute the time spent on the implementation of the first stages of information system development, allocating more time to the analysis and design of the software environment at an abstract, conceptual level. Results and their significance: the stages of analysis and design do not require large financial costs and are more variable. Information at these stages is easier to adjust and change than, for example, at the stage of writing program code. In addition, it is at these stages that the most active interaction between the developer and the customer is carried out, where maximum visibility and variability of the project of the future information system is required. And the use of modern software design methodologies significantly increases the efficiency of the first stages of information system design.
