Description
Automated system-cognitive analysis (ASC-analysis) for images provides automatic identification of specific characteristics of the given images from the color of the pixels and image edges, the synthesis of generalized images of pictures (classes), identifying the most and the least specific image features for the class, determining values of features of images for their differentiation, deletion low-value characteristics (abstraction) from the model, problem solving for quantitative comparison of specific images with generalized images of classes and generalized images of the classes with each other, and objectives of the study of the simulated subject area by studying its model. The work discusses the new features of the ASC-analysis and its implementing intellectual system called "Eidos" for identifying features of images using their spectral analysis, formation of the generalized spectra of classes, the task of comparison of images of specific objects to classes and classes with each other in their spectra. For the first time, it became possible to form the generalized spectra of classes with weights of the colors according to their degree of specificity and unspecific features for classes, and it is not the intensity of the color in the spectrum, but the amount of information in the color on the linking the object with that color to the class. In fact, there is a question of generalization of spectral analysis by using intelligent cognitive technologies and information theory in the spectral analysis. First, everyone is talking about the fact that spectral lines contain information about which element or substance is included in the object, but no one bothered to count what exactly the amount of information is and then use it to determine the composition of the object pattern recognition methods based on the use of this information. Second, spectral analysis is traditionally used to determine the elemental and molecular composition of the object; we propose to use it not only for that, but also to identify any images. A numerical example has been given

AGROINDUSTRIAL COMPLEX AND ITS ROLE IN SUPPORT OF NATIONAL FOOD SECURITY
Description
A comprehensive assessment of the state of the agro-industrial complex of Russia is given and its role in ensuring national food security is defined. The main directions of ensuring state food sovereignty in the conditions of global challenges are substantiated. The scheme of interaction between the world and national agroindustrial complex is presented. The main tasks of development of the agrarian sector of the economy are formulated: the growth of production per capita; ensuring physical and economic accessibility of food in the required quality and assortment. It was revealed that the volume of production of basic food products in Russia in 2015 did not reach the indicators of 1990, and the consumption of basic food products in Russia by individual items is significantly lower than the recommended rate. Deficiency of a diet of the population of the country on vegetables and melons, fruit, milk and dairy products is established. The expediency of reforming the agrarian sphere of the Russian economy is proved, including its accelerated adaptation to global challenges. They include geopolitical tensions, deterioration in the external economic environment and a reduction in external demand, mutual economic sanctions, fluctuations in inflation indices, and a reduction in consumer demand. It was concluded that for the increase in the efficiency of the functioning of the agroindustrial complex and the strengthening of national food security, technical and technological modernization of production, improvement of the mechanisms of state support, active development of the innovation environment are needed

ANALYSIS OF STAFFING OF THE HEALTH INDUSTRY OF THE KRASNODAR REGION
Description
Health protection of the population is one of the foundations of the constitutional system of Russia. The right of everyone to health care and medical care is enshrined in the Constitution of the Russian Federation (Article 41). This right is ensured by providing citizens with free medical assistance in state and municipal health care institutions, financing federal programs for protecting and promoting public health, implementing measures for the development of state, municipal, Private health systems. The quality of medical care depends on such factors as the material and technical base and the financial and economic conditions of the activities of medical organizations, the activities of public authorities in the field of health care, and the optimality of the use of resources. However, first of all, the quality of medical care is determined by the level of staffing of medical institutions, professional training and qualification of specialists. In the coming years, one of the strategic tasks of the Ministry of Health of Russia is to improve the quality of managerial personnel: the chief physicians of medical organizations, specialists in the fields of quality management, drug provision and financial and economic management. Until 2018, it is planned to conduct a large-scale upgrading of the managers who supervise financial and economic activities in medical organizations of all the constituent entities of the Russian Federation working in the MHI system

ANALYSIS OF THE COMPLEX AREA DEVELOPMENT PROJECTS IN THE RUSSIAN FEDERATION
Description
The article deals with the problem of realization of complex projects in the Russian Federation. A detailed analysis of the impact of integrated projects was carried out for the main parameters: the territorial and legal basis, the number of completed projects, the volume of attracted investments in the region, the volume of revenues of the project participants. According to the analysis of positive and negative practices of the implementation of complex projects in the regions with the highest gross regional product the Russian government recommended to pay attention to those complex projects that work "in the result", encouraging them, giving more preferences and privileges for investment and development of the territory as a whole. Some projects that are not only ineffective, but also bear the losses, should be reduced funding and in some cases to focus on their closure. As a result, it was concluded in part that the regions, which initially have a favorable socio-economic environment and the necessary infrastructure are more attractive to investors, and, naturally, more effectively develop. In such regions more residents come, due to which new jobs, growing the economy, increasing the gross regional product

Description
Based on the analysis of domestic and foreign scientific and patent literature, possible options to reduce weight of electro technical steel in magnetic circuits of electrical machines are explored. A search for the best options for the manufacture of magnetic induction motors stators technology aimed at improving the utilization of electrical steel and improving the energy performance of electric machines is carried out. All the variants are described and illustrated in detail in the drawings. It is pointed out the advantages and disadvantages of each method of manufacturing magnetic wires and the reasons why certain suggestions of technology of manufacturing magnetic circuits have not been implemented in mass production. The main indicators characterizing the manufacturability of constructive decisions are recommended. Economic indicators have been put in the basis of the choice of the optimal variant while designing the electrical machine. An optimal variant should be considered the variant in which all the technical requirements at lowest total cost are met. The latter should be understood not only the cost of materials and machine manufacturers, but also the cost of operation. The dependence of the energy performance of motors with modular designs of stators from the manufacturing technology is pointed out. The existing technology of the most mass electric motors series production, the following disadvantages are typical: low coefficient of utilization of electro technical steel; high specific material capacity, the cost of technology and labor intensity of production; low labour productivity and level of automation of technological process. Due to the fact that the possibilities of increasing of the machines’ specific weight characteristics due to the usage of new magnetic and dielectric materials are exhausted, it is advisable to change the technology of electric motors production, moving away from the traditional design

THE EFFECT OF PLANT FOOD ADDITIVES ON THE PROPERTIES OF WHEAT FLOUR AND DOUGH
Description
The article presents data describing composition of macronutrients and food additives "Apple Powder" and food additive "Pumpkin Powder" obtained from secondary resources processing of apples and pumpkins with innovative technology that ensures their high antioxidant activity. Introduction of the studied food additives in wheat flour provides a boost of its antioxidant activity compared to the control (wheat flour without any additives). We have revealed that the introduction of the studied food additives in wheat flour provides a strengthening effect to the gluten flour, while dietary Supplement Powder called "Apple" has a strengthening effect on the gluten of wheat flour compared with a dietary Supplement called "Pumpkin Powder". We proved a positive impact of food additives on the gas-forming ability of wheat flour and water absorption capacity of dough; at he same time, with the same dosage of additives, water absorption capacity of dough with the introduction of additives of "Pumpkin Powder" is higher than this figure with the introduction of the additives of "Apple Powder", due to the higher content of pectin in the additive "Pumpkin Powder " compared with the additive "Apple Powder", having a high water-holding capacity. We have found that the dough with the introduction of the investigated supplements has the best rheological properties in comparison with control samples. The obtained results allow us to develop evidence-based formulation and technological modes of production of bakery products enriched with antioxidant properties, with the use of food additives called " Apple Powder" and "Pumpkin Powder"
