Authors: Vitkovskyi Yurii
Published: December 2022

Introduction. The development of innovative activities ensures the adaptability of agricultural enterprises to chang-es in the economic environment. The introduction of diversification ensures an appropriate level of competitiveness and financial stability of agricultural enterprises. The lack of focus of the enterprise management system on the development of innovative technologies leads to the risk of financial losses and weakening of the market position of the entity.
The purpose of the research is to develop strategies for innovation and investment activities of agricultural business-es and models of their development.
Results. It is established that innovative, scientific and technological activities ensure the transformation of agricul-tural enterprises at the national level and ensure their entry into the world economic space. Manifestations and essence of innovative activity of domestic subjects of agrarian business are characterized. Possibilities and difficulties in the process of simultaneous introduction of innovative and diversification activities in the practice of domestic agricultural enterprises are outlined. Changes in the introduction process of the diversification strategy of the agricultural enterprise in the conditions of crises of the economic environment are characterized. The expediency of technical re-equipment of enterprises of the agri-cultural sector as innovations during the economic crisis is substantiated. External systems for implementing strategies to diversify the activities of agricultural enterprises are identified as a precautionary measure to prevent their internal crises. The main problems that hinder the development of full-fledged diversification and innovation activities of agricultural enterprises are outlined, and measures to intensify diversification strategies are proposed.
Conclusions. It is expedient to carry out strategic development of agrarian business entities with the introduction of diversification strategies into innovation activities at the micro and macro levels. This will ensure the maintenance of com-petitiveness and adaptability of agricultural enterprises in an unstable economic environment.

World grain market: place and role of Ukraine
Authors: Dovgal Olena
Published: December 2022

Introduction. The article shows the increase in Ukraine's share in the world structure of grain exports. The average value of the growth rate of Ukrainian wheat and fodder grain exports is calculated, which is ahead of the similar world indicator. It turns out that the food supply of individual countries and regions depends on the volume of Ukrainian grain exports. It is noted that the positive side of the growth of grain exports is the increase in foreign exchange earnings, the negative - the loss of value added and reducing the use of grain for domestic needs. Purpose. Substantiation of theoretical and methodological provisions of the grain market, study of the state, patterns, prospects of the grain market of national and regional nature and development of practical recommendations for improving the organizational and economic mechanism of its regulation through generalization of conceptual approaches and implementation of foreign experience. Results. The article proves that the solution of the global food problem is connected with the production of grain products. Currently, the essence of this problem comes down to the fact that the growth rate of the world's population is ahead of the growth rate of grain production. In addition, the article substantiates how the negative impact of destructive factors on agricultural production is increasing - reducing the area of land suitable for agricultural production through construction and desertification, increasing freshwater shortages, increasing the frequency of floods, droughts and fires and increasing their distribution and more. Conclusions. While maintaining the current demographic and climate trends, the risks of food danger are increasing even for countries that have traditionally been and are suppliers of grain products to the world market. For Ukraine, such risks are because the deepening integration of its economy into the world weakens the ability of public administration to influence the redistribution and movement of food in the national market - free trade policy is the basis of the neoliberal doctrine of economic globalization. In the worst-case scenario, the owners of grain products grown in Ukraine will be foreign agricultural holdings of TNCs, which will export it abroad without restrictions provoking an acute shortage of food in the domestic market with all the negative consequences. Keywords: wheat, fodder grain, export, foreign exchange earnings, raw materials, value added, domestic use.

Introduction. In today's economic environment, intensive production is the highest priority due to limited resources. It is important for agricultural enterprises to implement methods of intensification of activities, in particular through the use of advanced technology.
The purpose of the research is to substantiate the impact of agricultural engineering on the creation of competitive advantages in agribusiness.
Results. It is established that the Ukrainian machine building industry is characterized by negative tendencies. The dynamics of the agricultural machine building market is analyzed and the unstable nature of changes is determined - market volume growth during the period 2012-2016 and decrease during 2017-2018. The growth rates of volumes and structure of segments of the market of agricultural engineering (in terms of crop production, animal husbandry, universal engineering and spare parts) are characterized. It is determined that most of the equipment falls on the crop segment. The dynamics of availability, renewal and disposal of agricultural machinery in the activities of domestic agricultural enterprises is charac-terized. The reduction tendencies of the quantity of agricultural machinery by segments are noted. The market of imported agricultural machinery is characterized. The information on the production of certain types of mechanical engineering products for agriculture for the period 2013-2018 is summarized. The influence of agricultural engineering as a supporting industry on the competitiveness of domestic agriculture is characterized. The information on the use of agricultural machin-ery in households is summarized.
Conclusions. Agricultural engineering has a significant impact on the formation of competitive advantages of agri-cultural businesses. The agricultural sector is characterized by a reduction in the use of agricultural machinery and a focus on imported machinery.
Keywords: agriculture, agricultural machinery, agricultural machine building, competitiveness, competitive ad-vantages, factor.
Methods of strategic management in the field of health care
Authors: ROGACHEVSKYI Oleksandr
Published: December 2022

Introduction. The issue of strategic management in the health care field is very acute for Ukraine, as to date, the heads of health care institutions do not use the tools and methods of strategic management to organize activities in such institutions. Thus, all this highlights the need to study the methods of strategic management in the health care field and find out the optimal mechanisms for their implementation.
The purpose of the article is to analyze the methods of strategic management in the health care field for the develop-ment of the national industry.
Results. In the course of research, the materials of our own researches, and also separate scientific publications of na-tional and foreign authors concerning methods and tools of strategic management are used. Such scientific methods as mor-phological analysis, analysis and synthesis, empirical approach are used. Theoretical analysis of existing methods and tools of strategic management is carried out. Emphasis is placed on the fact that the methods of strategic management in the field of health care are based on the laws and patterns of intra-industry management, which also take into account the scientific and technical level of development in the medical field. The role of a systematic approach in strategic health management is explained.
Conclusions. According to the results of the study, it is proved that the unstable situation in the international envi-ronment and the impact of certain global factors, which include the COVID-19 pandemic; competition, significant develop-ment of medical equipment and technologies, determine the historical transformation of traditional management methods in the field of health care. Applying a systematic approach to strategic management of the industry expands the possibilities of planning long-term health care policy and determines a multi-purpose and comprehensive approach to intra-industry or-ganizational and functional segments of the national health sector.

The problem of grain futures functioning at the insurance market in Ukraine
Authors: REZNIK Nadiia , Yarmoliuk Anatolii
Published: December 2022

Introduction. The article proves the need to create markets for the main types of agricultural products in the agro-industrial complex, as a result of which their activities are based on modern infrastructure and markets, therefore, the futures market will help buyers and sellers to insure their price risks. Moreover, fluctuations in world markets will not particularly affect the income of farmers and the agricultural sector of our country in general. Farmers will gain confidence in their in-come for the year, and they will not be so worried about losing the "good" price, because all their possible losses or theoreti-cal income will go to a futures contract to speculators.
The purpose of this work is to study the problems of grain futures at the insurance market in Ukraine in modern conditions and prospects for their solution.
Results. The methodological basis of the study is the current legal framework, legislation, regulations, instructional materials, special literature. General scientific methods of analysis and synthesis, induction and deduction, ascent from the abstract to the concrete are used in the article, as well as specific methods of analysis. The possibility of delivery or receipt of cash, which helps the market to properly assess the futures on the cash market at the end of the contract is proved, ie at this time the prices in the futures and cash markets converge. It is highlighted that this process makes hedging an effective way to protect against adverse price changes in the real market, and the lack of supply in this case should not cause distrust of the tool as a whole. Conclusions. Problems of risks insurance of price change for grain by means of futures contracts are consid-ered. In modern conditions, the use of financial instruments to ensure the price risks of grain is becoming increasingly im-portant, in this context, the basic principles and the possibility of their use in modern economic and legal components in the country are analyzed. In modern conditions, we can talk not only about the impact of stock exchange futures on spot prices in the country, but also about the impact of spot prices on futures.
Keywords: futures, futures market, grain futures, world market, insurance market.
Domestic government loans as a modern investment trend in the system of international and national movement of capital transfer: challenges and prospects
Authors: LAGODIIENKO Volodymyr , Kostylianu Vitalii
Published: December 2022

Introduction. The article is devoted to substantiation and comprehension of the concept of investments in modern economic conditions. Modern research in world economics does not have a clearly defined concept of investment, because this concept should take into account not only its types, but also the depth of understanding of this process, its dynamism in the modern world. The mechanism of the investment process is to be clear and transparent for everyone who chooses any direc-tion for investment.
The purpose of the article is to analyze the theoretical and methodological aspects of investment areas, determine the nature, structure of the functioning mechanism of domestic government bonds, determine the effectiveness of investment areas.
Results. The usual areas of investment have ceased to provide a stable return for Ukrainian investors. Therefore, the issue of finding modern investment trends that ensure the most efficient use of investment capital becomes acute. It is im-portant to pay attention to the movement of both international capital and resident capital, because its speed creates a posi-tive investment climate inside the country. The investment process helps to ensure the proper functioning of all economic institutions. Therefore, it is important to consider current investment trends from the average investor, to analyze all possi-ble risks and warnings about a particular investment direction. One of the effective measures to eliminate the crisis in Ukraine is the issue of domestic government bonds. This approach allows attracting additional funds, which are used by the state to cover the budget deficit. In today's reality, this process is a means of lending that is more efficient than loans from other countries. In the modern economy, the development of investment areas is the driving force, so we believe that the topic of investment is relevant, because such measures are developed by businesses, which, in turn, develops economic sectors and the economy as a whole.
Conclusions. The article reveals the essence of the investment process. All modern investment directions are defined, their components are considered and characterized. It is justified that the need to invest only in clear areas of investment. The estimation of all offered directions of capital transfer is considered and carried out.
Key words: investments, directions of investment, domestic government bonds, investment risks, investment capital, capital movement, non-resident investors, capital attraction, investment asset.

It is not that world which had controlled by dictators; it is the world of democracy that means the will of the people. It is not the 20th century where too permeated by ideological struggles [e.g., communism vs. capitalism]. It is the world of innovative ideas to explore beyond borders and traditions. It is the first half of the 21st century where market economy overarching drivers of the world nations and where soft power played a diplomatic role across the world. Many regional nations have been influencing world politics because of their geo-political importance and emerging economic power. Such as China and India shaping the world structure differently on the international scenario. All the nations stand like a pawn on their international chessboard. Every country changing their economic and diplomatic policies step by step to survive on this power game politics. as an emerging power and global ambitions, India does not have the chance to follow its traditional policies such as non-alignment and so. This is the alarming time for India to shift its policy from non-alignment to multi-alignment by putting its advantages such as diaspora, culture and regional technology forward to play a dominant role on the world stage. India was recognized as the hub of the vaccine manufacturing of the world where it had not even mask to wear after the coronavirus outbreak over the world. This is the best sign of how India is raising by overcoming its hurdles economically, politically and diplomatically. The economic experts said that India and China will overtake the global economy in the world. India rising from regional power to global power by changing its economic and diplomatic methods.
This paper will discuss, why India changing its economic and international policy and why India attained more economic and environmental security over the world stage and how these values could be useful to attain India's global power objectives. Secondly, how India could depend on its policy of multi alignment in the two blocked worlds and how it depends on China's response against India’s rise and its crucial security concerns.
Gender Disparity in India and the Role of the State
Authors: - Sanchita Jana , - Kalyan Kumar Sarkar
Published: December 2022

India has achieved a prestigious position in the world today with a fast growing economy, rapid urbanization, advancement in science and technology, and an expanding youth population. However, in order to achieve the goal of sustainable development, equal participation of women and girls is required. During the British era, gender oppression and inequality was openly practiced in Indian society. There were concerted efforts on the part of some socially enlightened reformers to uplift the condition of women in India but the overall idea was that women are born to remain subjugated and subordinated to the male dominance. Post independent India saw some more efforts on the part of the government ( both central government and state governments) to uplift and empower women so that they are able to find their suitable position in society. However, it is ultimately the attitude and honest efforts on the part of the common people which can bring about the much needed change that Indian society requires.

Machine Learning Methods with Link-Level Features
Authors: - Koffka Khan
Published: December 2022

This paper describes graph link level features. We describe three different kinds of them. We discuss distance-based characteristics that consumers might use, such as the shortest path between two nodes, which does not account for neighborhood overlaps. Then we discuss neighborhood overlap metrics like Common neighbors, Jaccard coefficient, and the Adamic-Adar index that measures how many neighbors a pair of nodes share in a fine-grained manner. The issue with this is that the metric will return a value of 0 for nodes that are more than two hops away or that do not have any neighbors. The global neighborhood overlap metrics, for instance, like Katz use the global graph structure to give us a score for a pair of nodes, and the Katz index counts the number of pets of all lands between a pair of nodes where these paths are discounted exponentially with their length.

Published: December 2022

The site of Sphinx (SBK.W-60), located about 80 km north of Khartoum in the western part of Jebel Sabaloka, has been investigated since 2011 by the Charles University Sabaloka Expedition. Eleven trenches contained settlement deposits relating to occupation by hunter-fisher-gatherers of the Khartoum Mesolithic (or the Early Khartoum culture) dated at the site between 8750 and 4750 cal BC. In addition, five of the trenches yielded also human skeletal remains in primary and secondary deposits, with the minimal number of individuals estimated following anthropological standards at 45 individuals. The demographic structure of the burial site shows no selection based on sex, but immature individuals, especially those under the age of one year, seem to be markedly underrepresented, which is not unusual in pre-Neolithic funeral assemblages. Dental diseases, especially periapical lesions and inflammatory changes, predominate at Sphinx; however, a very low incidence of dental caries was recorded. Healed traumatic lesions or fractures possibly of accidental origin occurred in only six individuals. One identified case of perimortem trauma on the right scapula indicates an act of inter-personal violence. Nevertheless, it is possible to perceive the population buried at Sphinx as relatively healthy and peaceful.

The effect of silica-containing additives, obtained by leaching waste magnesium-iron slag from copper-nickel production, on the strength properties of lightweight concrete on porous aggregate has been studied. It has been established that the introduction of SiO2 additives in the amount of 0,5–2,0 wt. % into the composition of concrete increases the strength of concrete at the design age by 15–40 % compared to the composition without additives. The additives also increase the specific strength of concrete up to 38–40 MPa, which makes it possible to classify the developed concretes as high-strength ones (Rud ≥ 25 MPa).

A comparative analysis of the composition and properties of titanosilicate powders obtained with the use of technogenic raw materials or being production wastes was carried out and their influence on the properties of cement compositions was studied. It is shown that the effectiveness of the action of nanodispersed titanosilicate powders depends on their specific surface area, phase composition, and on the method of introducing nanosized additives into the bulk of the cement matrix. Despite the differences observed in the chemical and phase composition, specific surface, and morphology, they all exhibit photocatalytic activity in the methylene blue decomposition reaction and self-cleaning and bactericidal properties in the composition of the cement matrix,accelerate hydration and increase the strength of the binder.

Method of structural synthesis of a technical vision system for the problem of area measurement
Authors:   Bashkir State Pedagogical University named after M. Akmulla, Iskhakov Almaz R.
Published: December 2022

The article presents the results of a study of the problem of structural synthesis of a vision system and its parametric identification using a new method based on the mathematical apparatus of the theory of modified descriptive image algebras. The theory of modified descriptive image algebras is a mathematical apparatus that allows one to formally describe the processing and analysis of images. In this mathematical apparatus, it is possible to describe the mathematical model of the measurement function of the technical vision system for the selected attribute of the observed object. To develop mathematical models, procedural and parametric transformations of images are used. Any mathematical model in the theory of modified descriptive image algebras has at least one variational parameter. In the course of parametric identification, it is required to calculate their values. This problem is multimodal and always has at least one solution. Numerical methods are usually used to solve the optimization problem. The article describes the algorithm for constructing a mathematical model for measuring the area using procedural and parametric transformations. The parametric identification problem is solved in the form of a nonlinear optimization problem. The visualization of the objective function has been carried out and recommendations for choosing the values of its variational parameters have been formulated. The collection of statistical data was carried out and a histogram was constructed, on the basis of which the distribution law for the measured value is selected. The statistical task of testing the hypothesis with the selected law of distribution of the general population according to the Pearson criterion is solved for a given level of significance. For the unknown parameters of the chosen distribution law, the estimation of confidence intervals was carried out. The materials of the article are applied in nature and have practical value. Using the proposed approach, it is possible to develop a measurement function for any feature of the observed object on a series of images.

By means of simulation computer modeling, an effective variant of constructing an identifier for the speed of an asynchronous motor of an electromechanical system of a sintering machine is analyzed. The mathematical and algorithmic basis of the adaptive speed identifier (ASI) of an induction motor with a squirrel-cage rotor (ACIM) is given. Using the developed mathematical description of ASI with a reference model and using the apparatus of Lyapunov functions, an adequate computer simulation model was created. Compared with the existing methods for constructing identifiers in sensorless asynchronous electric drives, the proposed version of the ASI allows taking into account the discrete nature of the supply voltage of the ACIM at the output of the frequency converter with pulse-width modulation (PWM) of the output voltage and changing a larger number of equivalent circuit parameters. The stability of the speed identification process is provided in a wide range, sufficient to stabilize the speed of the trolleys according to the requirements of the technological process of sintering machines. As a result, the accuracy of speed identification in static and dynamic modes of operation of the electric drive increases. Simulation confirmed the operability of the proposed version of the identifier, proposed options for setting the AIS components. Universal, important for practical application results have been obtained, which allow both to build a high-precision system for identifying the ACIM speed in general and to refine the setting of the coefficients of the proposed version of the identifier in particular. An important property of the developed version of the ASI is its operability without loss of accuracy at near-zero and zero speeds of rotation and close to the nominal load torque on the ACIM shaft. In this regard, the practical application of the developed version, in addition to the drive of the sintering machine, is also possible in high- precision positioning systems for electric drives for various purposes.

Anomaly detection is an important task in various applications and areas of technology and production, such as structural defects, malicious intrusions into management and control systems, financial supervision and risk management, digital health screening, etc. The ever-increasing flows of diverse data and their structural complexity require the development of advanced approaches to their solution. In recent years, deep learning methods have achieved significant success in detecting anomalies, and unsupervised deep learning methods have become especially popular. Methods of anomaly detection by methods of deep learning without a teacher are investigated in the work on the example of a set of electrocardiograms containing normal ECG signals and ECG signals of people with various cardiovascular diseases (anomalies). To detect abnormal electrocardiograms, an autoencoder model has been developed in the form of a deep neural network with several fully connected layers. Also, to solve this problem, a method is proposed for selecting the threshold for separating abnormal ECG signals from normal ones, consisting in optimizing the ratio of performance indicators of the autoencoder model by methods. The paper presents a comparative analysis of the effectiveness of applying various machine learning models, such as the one class Support Vector Method, Isolation Forest, Random Forest and the presented autoencoder model to solving the problem of detecting abnormal ECG signals. For this purpose, metrics such as accuracy, recall, completeness, and f-score were used. His results showed that the proposed model surpassed the other models in solving the problem with accuracy = 98.8% precision = 95.75%, recall = 99.12%, f1-score = 98.75%.
The Concept of Dog-rose in the Russian Folk Tradition (Based upon the Folk Riddles)
Authors:   Research Mordovia State University, Shesterkina Natalya V.
Published: December 2022

The paper discusses the peculiarities of word usage in the folk riddles about the bushes of briar and the results of their linguocultural analysis. The collections of riddles by V. V. Mitrofanova (the main one), M. A. Rybnikova and D. Sadovnikov (additional) served as the source material. The study describes linguistic and mythological mechanisms in the riddles about briar and its ambivalence (negative and positive evaluation). The author pays great attention to the “costume code” of a tree with its costume metaphor and costume elements, highlighting the similarity of briar with a person. Deciphering of many attributes of the bush present difficulties for analysis, that is why the author often makes her own suppositions about different versions. The paper also includes the separate elements of fairytales and legends about briar.
“And I also Want to Work, to Learn and to Live”: a Letter of A. Severny to M. Gorky
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Khroustaleva Anna V.
Published: December 2022

The paper discusses the correspondence of A. M. Gorky with a provincial forgotten writer Arkady Alexandrovich Vdovin (pseudonym Arkady Severny). Severny's letters to Gorky are not only the one of the few sources for Severny's biography, but also an important source of data for the yet-to-be-written history of the province's post-revolutionary literary life. They illustrate the mass literary movement of the 1920s and 1930s, and introduce new information about Gorky's informal interest in supporting the interest of aspiring authors in literary work. Gorky's correspondence with aspiring writers from the provinces enriches perceptions about the history of Soviet everyday life, characterizes the alignment of literary forces grouped around writers' unions, literary practices of local associations of proletarian writers, everyday behavior of their members. Severny is a writer who positioned himself as a member of the Moscow Association of Proletarian Writers. Little is known about his biography. The fact of his presumed residing in the Volga Region is retrieved according to some newspaper publications. They show that Severny repeatedly recited his poems in different corners of Saratov. His autobiographical poem “About Myself” published on 26th of the November, 1925 in “The Bolshevik Juveniles” demonstrates that he was taken into Komsomol and had a background of a factory worker. He accentuated his proletarian origin to get in touch with Gorky. In the early 1930s, Severny's letters to Gorky remained unanswered. The reason for this was Severny's attempt to sell Gorky's letters to him to the editors of the Leningrad magazine “Rezets”.

In the first third of the twentieth century a certain tradition of creating a handwritten book developed in Russian culture. To a large extent, it relied on the traditions of Old Russian literature, where the book was a multi-level semiotic object with a sacred meaning. Starting from the binding and the quality of the paper and ending with the content, the Old Russian book was called upon to glorify God and show the man as the image and likeness of God. A medieval book as a set of letter designations is read in at least four dimensions: color, graphic, sound and numerical. And only the totality of all these levels gives the fullness of meaning, reflecting the harmony of the world and the fullness of being. A unique document of the era was deposited in the IWL — a handwritten book by the writer Iv. Novikov, created in the early 1920s and includes the poetic cycle “The Veil of Oblivion”. Designed for the author in the traditions of pre-reform spelling, decorated with illustrations, this is a monument that has a special theological program, and the key to understanding it the author finds in the Russian Middle Ages. The study shows how the traditions of the art of the book of Ancient Rus` come to life and are filled with new meanings in the Soviet culture of the 1920s.
