The purpose of the current study was to identify the effect of the length of a vegetation period of the collection soybean samples on grain productivity and quality. The study was carried out in the southern part of the Rostov region in the fields of the FSBSI Agricultural Research Center “Donskoy” in 2018–2020. The climate is semi-arid with moderately hot summers. The soil is ordinary thick calcareous heavy loamy blackearth (chernozem). The forecrop was winter wheat. The objects of the study were collection soybean samples of the ARIGPR named after N.I. Vavilov. The study was carried out on 75 samples, including 52 middle early samples with 110-120 days of vegetation and 23 middle maturing samples (120-130 days of vegetation), differing in morphobiological and economically valuable traits. The analysis of a vegetation period, grain productivity and quality of the collection soybean samples has shown that in the southern part of the Rostov region the most variable trait was grain productivity (Cv = 22.5%). The less variable characteristics were protein percentage in grain (Cv = 3.8%), a vegetation period (Cv = 4.2%) and oil content in grain (Cv = 5.3%). There has been identified a positive effect of the length of a vegetation period of soybeans on grain productivity and oil content in grain for both groups of maturity, protein percentage in both groups of maturity having a negative dependence on a vegetation period. The study has shown that in the middle early group, the largest grain productivity was obtained with 117 and 118 days of vegetation, the highest protein percentage with 110 and 114 days of vegetation, and the largest oil content in grain with 118 and 120 days of vegetation. In the middle maturing group, the maximum productivity indicators were obtained for the samples with 126 and 130 days of vegetation, the maximum protein percentage with 122 days of vegetation and the maximum oil content in grain with 123 and 130 days of vegetation. The samples showing the maximum indicators will be included in further soybean breeding.

Published: December 2021

Rice can form not only white-color kernels, but also of red, brown and black colors. In black-color rice kernels, the pericarp contains anthocyanin, which has antioxidant activity and therefore has a positive effect on human health. The purpose of the current study was to develop rice samples with black pericarp. The paper has presented the study results of the hybrid population ‘Mavr × Kontakt’ of the second generation. The variety ‘Mavr’ has a black pericarp, the variety ‘Kontakt’ has a white one. In the process of hybridological analysis there have been identified the patterns of inheritance of the main quantitative traits affecting productivity; there have been identified the best samples, in which formed compact erect panicles and black kernels; there has been selected the initial material for breeding work. The study was carried out in 2020 on the plots of the ES “Proletarskoye” in the Rostov region. There was established that the color of pericarp was inherited according to the type of complementary interaction of two genes. There was found an overdominance and interaction of two pairs of genes of different strengths according to ‘plant height’. There was also seen partial positive dominance, transgressions, and digenic differences of the initial varieties according to ‘panicle length’. According to the traits ‘number of spikelets per panicle’, there was identified overdominance of large values and positive transgression. There were found the forms with well-kerneled panicles. The trait ‘1000 kernel weight’ was characterized by negative dominance and dihybrid cleavage of 9:6:1. There have been selected the best morphotype F2 forms with black pericarp, which possessed optimal plant height, long panicles, larger kernel size, and an average 1000 kernel weight.

Published: December 2021

The development of bakery industry is possible due to the use of such non-traditional raw materials as durum wheat. The purpose of the current study was to estimate the effect of varietal traits of durum wheat when mixed with bread wheat according to the results of rheological parameters of dough, technological and bakery estimation of flour. There have been studied technological indicators of grain, rheological and physical parameters of dough, general bakery estimation. There has been established that the high gas-forming ability of durum wheat allows it to be used (30%) as bread wheat improver during baking. However, the positive effect was present not in all years of the study. There has been estimated an improvement effect due to mutual compensation of the missing components and complementarity of the bread and durum wheat varieties. There was found that in 2008, 2010 there was practically no improvement effect when durum wheat flour was added to the mixture in a ratio of 30:70%. There was established that in 2015 the maximum bread volume of 930 cm3 and a good bakery estimation (flat surface, oval shape, golden brown crust, as well as fine thin-walled porosity with elastic light crumb) were obtained by adding bread wheat varieties to durum wheat varieties, which during the year of the study there was formed weak grain (dilute of dough was 110 u.f.; valorigraphic number was 46 u.v.). In 2020, the varieties used in the mixtures of both spring bread and durum wheat were of high quality, and bakery estimation gave excellent indicators both in the control (the variety ‘Tulaykovskaya 108’ with 1300 cm3) and in the mixtures with 1140–1255 cm3; the appearance of bread and crumb in almost all variants had an excellent mark. The largest volume of bread, 1255 cm3, was obtained when the durum wheat variety ‘Bezenchukskaya Niva’ was added to the mixture. Adding durum wheat flour to the mixture in an amount of 30:70% when baking bread reduced its staleness by 6.5% relative to the control (bread wheat); bread remains fresh for a long time with an elastic, quickly regenerated crumb.

Published: December 2021

The current paper has presented the trial results of the winter wheat varieties developed by the ARC “Donskoy” in 2018 -2020. Currently, the farmers have bred a lot of different wheat varieties, but they are not able to take into account all the peculiarities of their cultivation. The purpose of the current work was to study the features of the autumn and spring-summer vegetation periods of the winter wheat varieties developed by the ARC “Donskoy” in the area of dark chestnut soils of the Volgograd region. There have been selected 10 winter wheat varieties for the trials. The field trial was laid down on dark chestnut soils of the lands of the Serafimovichsky district in the Volgograd region. The study was carried out according to the generally accepted B.A. Dospekhov’s methodology. The field trials showed that the germination of winter wheat was influenced by a seeding depth, which was 7-9 cm. The best germination was found among the varieties ‘Asket’, ‘Etyud’, ‘Lilit’, ‘Donskaya Step’ and ‘Zhavoronok’. During the trials, the formation of a productive stand was greatly influenced by the weather (the length of a spring tillering period, precipitation in May), as well as the traits of the variety. The winter wheat varieties ‘Etyud’, ‘Shef’, ‘Donskaya Step’, ‘Krasa Dona’ were able to form a large number of productive stems under favorable weather conditions. Under insufficient moisture supply, the largest number of productive stems was formed by the varieties ‘Lidiya’ and ‘Lilit’. The highest tillering intensity during an autumn vegetation period was shown by the variety ‘Lidiya’ (4.7–6.2 shoots), including the varieties ‘Zhavoronok’ (4.2–5.4 shoots) and ‘Etyud’ (4.0–5.3 shoots). The largest productivity was produced by the varieties ‘Donskaya Step’ (4.97 t/ha), ‘Zhavoronok’ (4.95 t/ha), ‘Krasa Dona’ (4.90 t/ha) over three years.

Published: December 2021

The study of crop formation processes by constituent elements revealed the dependence of the parameters of the number of grains in the ear and the weight of barley grain at the same level of grain yield on the number of productive stems per unit area. It is established that the increase in the number of productive shoots per 1 m2 is accompanied by a significant decrease in the productivity potential of the ear in terms of the number of grains and the parameters of the mass of one grain. The correlation dependence of these yield elements on the stem density of barley is strong. In the studies of 2018–2021, the number of productive stems, plant height, productivity of one ear and weight of 1000 grains of spring barley varieties Daniele, Gezine, Beatrix, Soldo, 5/18, Fabiola, Sangria, Utah, 9/19, Mompi 19, Lyuba and Champush. Correlation holidays between these indicators were also established. The number of productive stems of spring barley varieties on average for 2018–2021 amounted to 0.87–1.39 pieces/1 plant. The average biotype ranged from 0.89 in 2018 to 1.47 in 2021. There was a medium and strong variation in the number of productive stems depending on genotypes. In most collection specimens, the rate varied greatly depending on growing conditions. Collectible samples 5/18 is a semi-dwarf, other biotypes are dwarfs. The highest plants were in 2020. The plant height of most cultivars varied slightly over the years of research. The average productivity of one ear of the analyzed collection samples was 0.63–1.17 g. The lowest indicators were noted in 2018, the highest – in 2020. The average weight of 1000 grains was 45.2–53.5 g with the highest indicator in 2021 g. The correlation between plant height and ear weight per ear was positive medium and close; between the number of productive stems and plant height – positive average, weak and negative average; between the number of productive stems and the mass of grain from the ear – a weak positive and negative correlation; between the number of productive stems and the mass of 1000 grains – the average positive and weak negative; between the height of the plants and the mass of 1000 grains and between the mass of grains from the ear and the mass of 1000 grains – from the average positive to the average negative.

Aims. To study the quality formation of a cupcake made from triticale flour enriched with pumpkin paste. Methods. Laboratory, mathematical and statistical, physicochemical. Results. The article presents the study results of the quality formation of triticale cupcakes (baking, shrinkage, moisute, volume, porosity), enriched with pumpkin paste. It is established that the quality of triticale cupcakes varies significantly from the pumpkin paste content. As a result of research, it was found that the baking rate of cupcakes varied depending on the pumpkin paste content and was 2.77–3.90 %. This indicator is the lowest in the control variant - without pumpkin paste addition – 2.77 %. Variants with the addition of 5, 15, 35 and 40% of pumpkin paste were characterized by high rates, where the baking rate was 3.72, 3.8, 3.85 and 3.9, respectively. In other experiment variants it was at the level of 3.14–3.63 %. Shrinkage of triticale flour cupcakes enriched with pumpkin paste did not change significantly and amounted to 1.0–1.4 %. It was found that with pumpkin paste addition, the moisture of the cupcakes increased from 21.4 with 5% of pumpkin paste to 36.1 % with 50 %. The highest moisture was characterized by variants with a content of 40, 45 and 50 % of pumpkin paste, respectively, 33.4, 33.2 and 36.1 %. When pumpkin paste is added to the dough, cupcake volume increases from 5 to 50 %. It is obvious that the absence of pumpkin gluten in the paste is the main reason for intensity decrease in the processes of dough leavening and increasing its density. Therefore, with pumpkin paste addition, the porosity of baked goods was not developed, the pores are small and thick-walled. Thus, cupcake porosity was 28.4–55.6 %. This figure was the highest with the addition of 5 % of pumpkin paste – 55.6 %, which is 5.4 % more than control. As the amount of pumpkin paste increased, the cupcake porosity also decreased. Conclusions. In the technology of triticale cupcakes, it is optimal to add 25–30 % of pumpkin paste by dough weight.
Justification of the limit of expediency of using potash fertilizers

Published: December 2021

The issues of the recoupment of potash fertilizers are considered, which is one of the most controversial in agronomy, since it is precisely this that determines the need for fertilizers and the economic efficiency of their use. It is shown that the payback of fertilizers is a complex value and not constant in different crops. The increase in yield from fertilizers in kind is taken on the basis of field experiments with fertilizers carried out on podzolized chernozem in the Uman NUS. The cost of the increase in yield from the use of potash fertilizers was determined by the average actual sales prices of products prevailing on the market through various sales channels in the 6th quarter of 2021. collecting a yield increase from potash fertilizers. The cost of potash fertilizer was taken at the current price of 16000 UAH/t with the addition of a margin for their delivery to the farm. The costs for the use of fertilizers on the farm and for collecting the increase in yield were set calculated according to the accepted standards. The difference between the value of the yield increase (YI) and additional costs (AC) gives the net income received from the use of fertilizers. The ratio of the cost of increasing the yield to additional costs shows their payback. On the basis of comparing the indicators YI and AC, the boundaries of the economic efficiency of the use of fertilizers were determined: YI>AC (general expression of the task). The minimum necessary increase in yield from fertilizers and the limits of the increase in prices for potash fertilizers were also calculated. It has been established that at a price for potassium chloride of 16000 UAH /t and the cost of its use in optimal doses for field crops against the background of a balanced nitrogen-phosphorus nutrition, the cost of an increase in yield is 1164–14820 UAH/ ha. Payback (unprofitableness) of 1 kg. potash fertilizers vary in a wide range – from – UAH 18.6 to 104,0, depending on the crop. The limit of the unprofitable price per unit of the active substance of potash fertilizers at the optimal dose of application depends on the crop and is in the range of 6.9–129,5 UAH/ha. With the current disparity in prices for crop products and potassium chloride, its use is unprofitable for winter rye, spring barley, grain sorghum and sugar beet (when applied against a background of 40 t/ha of manure). This is due to the availability of podzolized chernozem with mobile potassium compounds, biological characteristics of crops and technologies for their cultivation.

The article presents the results of vegetation-field studies (for 2018-2020) to study the effect of trace elements on the yield and quality of greens and root crops of parsley on heavy loamy chernozems on loess-like loams. A soil mixture was poured into the vessel at the rate of 10 kg of heavy loamy chernozem. Microelements were introduced into the soil in an amount: boron – 1.0 mg; zinc – 2.5 mg; copper – 0.5 mg; manganese – 5.0 mg; molybdenum – 1.0 mg; cobalt – 1.0 mg; iodine – 2.0 mg of active ingredient per kilogram of soil. In the prepared soil, 100 parsley seeds were sown in vessels at the beginning of May. Trace elements were aplicated in the form of an aqueous solution of salts 20 days before chemical analyzes. Molybdenum in the form of ammonium molybdenum (0.05 % solution), manganese – in the form of manganese sulfate (0.6 %, solution) and boron – in the form of boric acid (0.15 % solution). The experiments were carried out in triplicate. Collecting greens was carried out when the plants reached a height of 20–25 cm, leaving petioles 2 cm high from the head of the root crop. The results of the research found that microelements: boron, copper, manganese, molybdenum and cobalt on chernozem on average over two years contributed to an increase in seed germination by 1.2–1.3 %, and the introduction of iodine into the soil slightly reduced seed germination. Parsley shoots appeared together, which was also influenced by the water–air properties of the soil. At the same time, the plants were well leafy and had a darker green color of the leaves, increased the productivity of greens and parsley root crops. In the variant where organic fertilizers were applied to the soil under the predecessor, the microelements increased the yield. This is due to the fact that organic fertilizers were introduced under the previous crop, when decomposed in the soil, they provide the plants with microelements. The increased yield of parsley root crops was obtained from the introduction of molybdenum and a double dose of copper. An increased yield of root crops compared to the control (without feeding) was obtained, respectively: cobalt – 151 g, double dose of copper – 135 g, copper – 108 g and zinc – 106 g. Thus, the use of trace elements for parsley in order to obtain high yield and quality marketable products are best used on poor soils of these elements.

The role of education as a socio-economic variable of the country in the context of globalization is constantly growing. Its multidimensionality is the subject to the functions implemented in the relations between society and the economy. The social, cultural, spiritual and educational function of education is a significant and indisputable subject of study in the relevant sciences. The recognition of the economic role of education, the development of estimates its effectiveness and the direction of its growth is a problem which solution depends on whether the striking discrepancy between the productivity of education and the expectations of the economy regarding its importance will be canceled. Obviously, the economic role of education is realized, first of all, in relation to its economic growth. As the development of intellectual potential is a product of the education system that develops new knowledge, provides innovative and technological improvement of production and its embodiment in an increase in the social product, which stimulates economic growth. The aim of this paper is a scientific and experimental review of the economic conditions for the development of world educational systems in the context of globalization. The main background to the development of education is the proper investment in it. Typically for European countries is the fact that most expenditures on education is in the form of government consumption, although it is the consumers who actually spend the most. However, measuring costs only in this way significantly underestimates them, since a more subtle form of costs is completely missed: the opportunity cost of lost wages, since some students are not able to be involved in employment during their studies. It is estimated that the total cost, including the alternative cost of education, are twice the direct costs.
Communications in insurance management

Published: December 2021

Communications are a connecting element of the management process. Management activities are inextricably linked with the need for constant exchange of information (communicative activities) to coordinate the work of units of the organization and individuals, aimed at achieving common goals. The article is devoted to the consideration of communication issues in modern insurance organizations with an emphasis on their essence, key elements and main stages of the communication process. The essence of communications in the categorical section is clarified and scientific approaches to the formation of the definition of this category are generalized. Thus, it is determined that communication is a process of exchanging ideas and information, which ultimately leads to mutual understanding. This interpretation of the concept of communication is shared by most domestic researchers who have studied the outlined issues. The types, kinds and classes of communications of the insurance company are investigated. The range of communication tasks is outlined and the set of functions of the latter in the management process is determined. The study allowed to form four key tasks of communications in the management process: a combination of all elements of the management process; assistance in making management decisions; providing information on the entire management process; ensuring interpersonal relationships in the team. According to the results of the study, the key functions of communications in the management process include: managerial, informative, emotional, control and factual. The key stages of the communication process are considered, of which according to the results of the research four are singled out: the first – formulation of the idea and selection of information; the second – coding and channel selection; the third is transmission and the fourth is decoding. It is established that communication as an exchange of information between people (or groups of people) has three aspects that are most important for assessing the content of management activities, each of which is considered from the normative-organizational and individual-psychological positions. In the first case, communication is determined by its objective organizational forms, the requirements for the effective implementation of a rational communicative process. The second aspect of communication is based on the psychological characteristics of communication partners and explains a number of important features of interaction, including those that hinder the effective development of communication. According to the results of the study, it is determined that communication is a semantic aspect of social interaction, one of the most common characteristics of any activity, including management. It is a modern form of political, scientific, organizational and technical force in society, through which the organization is included in the external environment, the exchange of views or information to ensure mutual understanding.

The article investigates the current causes of international labor migration and its connection with human development. The purpose of the study is to summarize the causes of international labor migration, to substantiate the causes and consequences of migration in Ukraine, which have their own characteristics and their impact on human development. The essence of international labor migration and the evolution of views on its movement are determined. It was established that modern migration was called by a whole range of driving forces, a set of several reasons that depend on economic, social, demographic and political factors. It is justified that in Ukraine, which is a donor country, the causes and consequences of migration have their own characteristics and their impact on human development. New conditions for labor migration in the modern world should be considered in terms of the category of human development, which reflects the process of forming a socio-economic environment of human existence, which ensures the freedom of choice to have a decent standard of living, to be healthy, educated, to live in an environmentally friendly environment, safe, with a fair justice system. Economic factors have the greatest impact on Ukrainian migration, and first of all, this is a difference in wage levels, which is 2 times less in Ukraine compared to the EU countries. The refusal of mass return of external labor migrants to Ukraine may indicate a significant change in the motivational factors of external labor migration, when the ratio of level and quality of life in donor countries and recipient countries plays a decisive role. Remittances of migrants have a positive impact on the development of human potential. Additional cash flows to households experiencing the greatest need for them have a significant impact on financing the economic and human development of the country, which consists in overcoming poverty, forming an additional source of public investment, reducing risks during crises, financing infrastructure development.

Modern science pays a lot of attention to solving issues of the company's functioning under the influence of crisis phenomena and processes. Nevertheless, the conditions of modern development associated with high risk, sudden transformations, crises and shocks, the main task is set by the study of the latest elements of company diagnostics. Based on this, diagnostics of the company's crisis state is a fundamental component of the successful development of agricultural companies. It is considered as one of the areas of economic diagnostics and is closely related to the diagnostics of the threat of bankruptcy. It is also important to note that the main component of diagnosing the level of effectiveness of antisipative management of enterprises with an agricultural direction is the definition of a system of criteria for identifying specific causes leading to a crisis situation and a failure in agricultural activity, which has a very important scientific, practical and methodological significance for economic science.The main purpose of the article is to study the problem of bankruptcy diagnosis at domestic enterprises, substantiation of theoretical provisions and development of practical recommendations for improving the diagnosis of antisipative management of enterprises in the system of management diagnostics. The article identifies the main tasks facing enterprises seeking to prevent and prevent the onset of crisis situations, analyzes the stages of diagnosis and considers the main models for predicting the bankruptcy of the enterprise. It was found that the models show real results only in the conditions for which they were created. That is, it is necessary to develop a model in which the assessment of the financial condition of agricultural enterprises would be based on domestic accounting and reporting standards, which would use the statistical, information base of domestic enterprises taking into account the specifics of the industry.

An author's approach to the application the simplified taxation for farmers that is legally contained in the Tax Code of Ukraine has been developed and systematized in the paper. It is determined that tax incentives for farmers are applied through the use of a simplified taxation system, which purpose is commonly agreed state interests and the economic growth of taxpayers. Priorities have been identified that determine the lasting economic expansion of agricultural production, aimed at increasing the production volume and sales. It was also pointed out that the essential to the creation tax incentives mechanism for the agricultural sector is an effective tax administration, through which the resistance and stability of the tax system is ensured. The main assignment of the current tax tools for encouraging economic sectors has been formed, which is defined as monitoring of the incentives effectiveness. The influence on the taxation of business entities in the agricultural sector, which is reflected in the administration and management of the tax system, in particular, the application of digital technologies, has been determined. It is noted that the introduction of digital technologies into the taxation provides the capacity for monitoring has increased due to the increase in technology, hardware and software for inspection, processing, transferring and analyzing information with a decrease in human participation and an increase in the objectivity of control. Moreover, the strategy of tax incentives for the growth of the agricultural sector, which should be introduced into the national tax system, is of great importance in the taxation of economic entities in the agricultural sector of the economy. A mechanism for taxation with flat tax was created, in which the entire amount of the tax liability remained at the disposal of the agricultural enterprise and was directed to expanded reproduction. It is determined that an important prerequisite for improving tax incentives for the agricultural sector is the effective land use by business of all forms of management. It was also proposed to use the increase coefficients for the land (single) fourth group of tax for the misuse of agricultural land.

Microeconomic analysis of exports and imports of agricultural organic products in Ukraine. Organic agriculture is a way of conducting agricultural production on the conditions of sustainability, which with the help of natural, technologically unprocessed means allows to produce agricultural products - organic food. In recent years, Ukraine has seen a rapid change in the structure of the market for organic agricultural products. The progressive increase in demand for organic food is a consequence of a healthy lifestyle. Demand for organic products is the result of consumer demand for certified agricultural products using organic technology, producers' demand for organic raw materials for further processing and export volumes. The market supply for organic agricultural products is defined as the sum of the supply of organic products, which is formed by agricultural enterprises and the volume of products through imports. Demand and supply of organic consumer products in the world and in the European Union in recent decades have shown exceptional growth dynamics. In Ukraine, the market for organic products is small, but is growing systematically. In 2020, the domestic market for organic agricultural products was estimated at approximately 24.3 million euros. Domestic organic products are exported to more than 40 countries. Recently, domestic organic products are exported mainly to the Netherlands, USA, Switzerland, Germany, Great Britain, Lithuania, Austria and Poland. The main organic products exported from Ukraine over the past five years are corn, wheat, soybeans and sunflowers. The growth of the organic market for agricultural products is changing the role of exports and imports. However, in today's conditions, the volume of exports of organic agricultural products significantly exceeds the volume of imports.

A factor in ensuring reproduction in agriculture is the development of a bank lending system. Currently, the need for credit resources in agriculture requires further development of a specialized system that would meet the requirements and conditions of a modern market economy. Issues of formation and development of the credit system in agriculture are considered both by domestic economic theory and practice and by countries with developed market relations, which are based on the development of the infrastructure of modern credit relations, forms and methods of lending. The sphere of agricultural lending is in the process of formation due to imperfect legislative provision, underdevelopment of the credit products market, and the absence of the vast majority of market infrastructure entities. Solving these problems will help expand the availability of agricultural producers to credit resources, as well as ensure the stabilization and development of the industry. Agricultural production is a strategically important sector of the national economy, the development of which depends on the level of food and national security of the country. The development of the modern agricultural sector as the most important component of the national economy largely depends on external sources of financing, the main of which is bank lending. State support for lending to farmers is an objective necessity. At the same time, limited access of farmers to credit resources of banks makes it impossible to increase production efficiency. Increasing the availability of farmers to credit resources is one of the priority areas for ensuring the dynamic development of agriculture, their functioning on self-financing and self-sufficiency. A well-established lending system plays an important role in lending to agricultural producers. Studies on the development of the bank lending system for agricultural producers indicate the lack of a developed legal framework for providing farmers with bank loans for both operating and investment activities. Preferential lending regime introduced in the practice of lending to farmers in modern conditions does not work due to lack of budget funds.

Published: December 2021

This study sought to analyse the extent of the application of Fourth Industrial Revolution techniques (4 IR) in the tourism sector of Zimbabwe using the Victoria Falls as a case study. The objective of the study was to analyse the effectiveness of 4IR technologies on the competitiveness amongst tourist operators and to determine strategies that could be adapted to improve the use of 4IR technological trends. A sample of 96 tourist respondents were used in the study, as well as 30 tour operators. The study also used probability sampling through systematic random sampling for tourists and non-probability sampling through random sampling for tour operators. The findings clearly showed that pre-travel technologies used by tour operators have enhanced tourists  choice of patronage. However, on-site technologies used by tour operators were limited acording to tourists who indicated that they were not satiesfied with the extent to which on-site technologies were applied. The reasons behind slow adoption of 4IR technologies by most operators  emanated from lack of managerial skills, lack of expertise and lack of desire to innovate. The study recommended that operators should urgently adopt the use of artificial intelligence, they should budget towards technological upgrading as well as installation of cyber crime security systems. Organisations should also invest in digital transformation.

Most of the innovative changes in higher education in relation to academic capitalism are based on market principles. The aim of the article is to further study and determine the innovative directions of the reform of higher education. For this, it is necessary to create and implement a scientific and applied system that combines theoretical and practical approaches to the innovative development of higher education. The authors propose the further development of a new scientific direction in the field of higher education - “innovatics of higher education”.

Theoretical foundations and practical issues of higher education innovatics include innovative changes in a number of activities. The main of these activities are: teaching, training and study; R&D, engineering, IT and technologies development, projects activity and design creativity; financial and economic support of the educational process, R&D, activities development and business expanses; inventive and patent-licensing activities, technology transfer, academic/university entrepreneurship;  cultural and moral development, upbringing of cultural, moral and human values; sports, recreational, festive and extracurricular activities including other types of universities activities.

Thus, innovatics of higher education includes innovative changes in almost all areas of higher education to enhance the quality training of professionals and responsible citizens of the modern community. More over innovations can guarantee financial independence, economic stability and competitiveness for a university development.   This will be useful both for reforming the higher education systems and for universities R&D in Ukraine and other countries.

Authors: Milto K.D. , Bezman-Moseyko O.S.
Published: December 2021

The field surveys were conducted in the Maninjau Lake region, Sumatera Barat, Indonesia, in February 2020, mainly on the north-eastern slope of the Maninjau caldera at 450–600 m a.s.l. The slopes of the Maninjau caldera are naturally covered by a tropical rainforest that remains quite undisturbed from an altitude of 900 m up to the crater ridge. Natural vegetation of the northern and eastern slopes at altitudes from 450 and 500 to 600 m a.s.l. is replaced by rice plantations or mixed forest gardens. The typical habitat consisted of an evergreen broad-leaved forest on the slopes along a mountain creek and around a waterfall. Herein, we report 11 new species records for the Maninjau caldera; 9 new species records for Agam Regency; 3 new species records for Sumatra and Indonesia and 1 species of Cnemaspis Strauch, 1887 new for science. The morphology of rare and poorly known species of the bent toed gecko, Cyrtodactylus agamensis (Bleeker, 1860) is described for the first time. A high diversity of Cyrtodactylus Gray, 1827 occurs in Indochina and on the Thai-Malay Peninsula (150 species) but only six species in Sumatra. The Malay-Indochinese genus Cnemaspis has a recent spurt of diversity and now reaches eight species in Sumatra and only one species reaches Java. Current gecko diversity in Sumatra comprises 29 species in eight genera. The level of endemism level in geckos is very high and reaches 48%. The herpetofauna of Maninjau Caldera includes 26 amphibian and 46 reptile species. The faunistic core of the West Sumatran herpetofauna consists of Malay-Sundaic, Sumatran endemic, Sunda-Indochinese and widely distributed Oriental elements. The West Sumatran herpetofauna is characterized by the presence of a mutual species with Indochina, Malaysia, east India, Myanmar, the Andaman and Nicobar islands and Sri Lanka, often with disjunction in the huge territory of Indochina; species with continuous distribution from the Indian subcontinent to Papua and Oceania; and generalist species with wide pan-Indopacific distribution.
On the Taxonomic Status of the Red Icefish Channichthys rugosus (Notothenioidei: Channichthyidae) from the Kerguelen Islands (South Ocean)
Authors: Nikolaeva E.A.
Published: December 2021

The presented work is the final part of the taxonomic revision of the Antarctic icefishes of the genus Channichthys Richardson, 1844 (Notothenioidei: Channichthyidae) from the Kerguelen Islands, the species composition of which was discussed until recently. Based on the morphological study of all available specimens from the ZIN and BMNH collections (including the holotype), a comprehensive redescription of the Red icefish Channichthys rugosus Regan, 1913 from the waters of the Kerguelen islands (South Ocean) was carried out, including external morphology, seismosensory system, gill apparatus, and axial skeleton. As a result, new diagnostic features of Red icefish were discovered and previously known ones were clarified, which made it possible to confirm the species validity. Comparison with other valid species icefishes was done. Channichthys rugosus differs from Ch. rhinoceratus Richardson, 1844 by a high anterior dorsal fin, the fin membrane of which reaches the apexes of its longest rays (does not reach in Ch. rhinoceratus), as well as a narrow and concave interorbital space (compared to the wider and flat one), by stronger granulation and a uniform reddish body color (dark spotted-marble in Ch. rhinoceratus). Channichthys rugosus differs from Ch. velifer Meissner, 1972 by the number of rays in the first dorsal fin (7–9 versus 9–12) and pectoral fin (18–20 versus 20–21), the presence of bone plaques in the proximal part of the medial lateral line (absent in Ch. velifer), and monochromatic reddish body coloration (spotted in Ch. velifer). Channichthys rugosus differs from Ch. panticapaei Shandikov, 1995 by the presence of only 1 row of gill rakers on the first gill arch (2 rows in Ch. panticapaei) and by light coloration (brownish-black in Ch. panticapaei).

Purpose: Experimental determination of the response room function and its use to estimate the acoustic conditions in rooms with noncontinuous noise sources.

Methodology/approach: The detailed parameter calculation of noncontinuous sound fields using the response room function, which is the room response to pulse excitation. The response function can be calculated by analytical or numerical methods and by experimental measurements in production conditions the energy attenuation when a constant noise source is switched off.

Findings: Noncontinuous noise has a negative impact on health. The effective noise reduction is determined by the complete and accurate analysis of its energy parameters. The noncontinuous noise estimation based on equivalent levels does not meet the requirements, especially when pulsed noise sources are active. The experimental technique is proposed for the response function calculation and its use in evaluating the noise conditions in rooms with noncontinuous noise sources.

Practical implications: The experimental determination of the response function to pulse excitation allows studying the acoustic processes in rooms for the formation of noise conditions when analytical methods cannot be used. The experimentally obtained response function makes it possible to solve problems of changing the noise conditions in rooms with noncontinuous noise sources.

Published: December 2021

The analysis of the current methods and techniques of solving the problem of heat resistance of building envelopes with heat-conducting elements shows the solution of a onedimensional problem of heat resistance. One of the possible methods for determining the temperature fluctuation amplitude on the inner surface of the building envelopes with heatconducting elements is the modeling of non-stationary temperature conditions in the computer program. However, this solution causes great difficulties, as it transfers the specified calculation from engineering to scientific and cannot be recommended for practical application. The second method of solving this problem is the application of the convergence coefficient, which can be obtained empirically. The selection of the convergence coefficient allows for the influence of the heat-conducting elements on the weighted average surface temperature depending on the envelope configuration.

The structural analysis of the building envelopes and their impact on the averaged amplitude of oscillations on the inner surface are conducted. The arrangement of heat-conducting elements at the outer edge is characterized by a negligible influence of the vibration amplitude on the averaged amplitude over the structural surface. The arrangement of heat-conducting elements greatly affects the heat-conducting elements. According to the comparative analysis, the convergence coefficient is preferable in harmonics of the average temperature fluctuations on the inner surface.
