Published: June 2022

Inevitable integration of Ukrainian enterprises into European and world economic space will lead to growth of competitive struggle on the domestic market. Under these conditions, increases the role of politics prices of the enterprise, because obyzvodovannye, reasonable prices for products and services together with other components of the complex marketing can provide an effective, profitable activity and conditions for a stable longterm development of enterprises. Setting the appropriate level of prices for products is a difficult and labor-intensive task in the process of functioning of the enterprise. The price itself accumulates the level of success of the enterprise, which is reflected in the volume of sales and the size of profits and is significantly dependent on the level of costs. In connection with this the level of costs must be scientifically grounded and well estimated from the point of view of potential production capabilities of the enterprise and consumer demand for the products. The problem of cost optimization is not a one-time act, but a process that lasts throughout the entire market life of the product. Therefore, the company for the purpose of taking the right decision on setting the price for its products must consider all variants of reducing and optimizing costs for the production of products depending on the conditions of internal and external environment of the company at a given moment of time. The work specifies a methodical approach to rationalization of costs of the enterprise, according to which the reduction of costs of production without deterioration of the quality of products is ensured. Described the conditions of the resource supply by own abilities of the enterprise and / or obtaining the necessary resources from outside suppliers as a basis for reducing their costs. The necessity of implementation of proven measures in the present conditions of development in domestic enterprises was substantiated. The effectiveness of promoted measures to reduce costs of the enterprise through their testing in the activities of agricultural enterprises is presented.

Authors:   Uman National University of Horticulture, Polishchuk Oleh , Melnyk Viacheslav ,   Pavlo Tychyna Uman State Pedagogical University
Published: June 2022

The article summarizes the approaches to information and analytical support of the accounting and financial component of the agricultural enterprises’ economic security system. At the time of unstable economic situation in the country, effective management of agricultural enterprises requires the creation of a new information system that would provide reliable, high-quality, and timely data for management staff to make management decisions. This has led to an increase of an economic security’s role as one of the enterprise management system’s elements. The accounting and financial component of economic security is a system of economic management of the enterprise, located at the intersection of different management functions and areas of activity of the enterprise. In the current conditions of global socio-economic development, a very important component is the information and analytical support of the management process, which is the collection and processing of information needed to make the necessary management decisions. The management of agricultural companies is certainly tasked with obtaining accounting and financial information, its processing, as well as the further formation and transmission of new derivative information in the form of management influences. In the practice of economic activity for effective management must be developed accounting and financial policy, which should ensure the achievement and strengthening of the optimal level of the economy’s financial condition. Accounting, financial, tax, and management accounting data should be taken into account when implementing financial policy. Lack of necessary information, the use of doubtful or outdated data is a precondition for serious miscalculations in making the right decisions. Financial accounting is the basis of economic security and it is a defining element of the national accounting system, which is regulated by the government. The development of financial accounting in the agricultural production sector necessitates the unity of calculating methods’ system of financial indicators and proper information reflection through technical, technological, organizational, managerial and economic unity. Thus, one of the ways to raise the agricultural economy is to improve the information and analytical support of agricultural enterprise management, which confirms the relevance of the research topic.

Published: June 2022

The article discusses the stages of development of strengthening economic interdependence between states and individual participants in international economic relations. The local government has to adapt the national economy to the new conditions of functioning in the global space improving the levers of regulation of the main processes taking place in it. In recent decades, there have been rapid removal of barriers to doing business outside national borders including increasing trade, free movement of capital, labor force, and promoting scientific and technological exchanges between nations. The emergence of transnational corporations has led to the availability and the high quality of goods and services, more active investment, development of science and technology. There has been a recent debate over the benefits and harms of multinational corporations. Nobody should deny the tangible positive changes in the international economy since the creation and active spread of such companies around the world. However, proponents of anti-globalization theories are increasingly claiming that the negative effects outweigh the positive effects of TNCs, largely due to their growing power and imperfect legal framework to control their activities. International companies have the opportunity to exert great influence on governments, especially host countries, by engaging in various forms of manipulation in order to achieve their goals in the process of manufacturing, products sales, and profit maximization. The method of comparative analysis identifies possible advantages and disadvantages due to the activities of TNCs as the main result and at the same time the main cause of business transnationalization processes. It was found that the consequences for both home countries and host economies can be different depending on factors such as the level of influence of these companies, the attractiveness of the conditions for locating branches in a particular place, the common interests of both parties, the degree of regulation and effectiveness of the regulatory mechanisms of mutual relations.

Authors:   Vinnytsia National Agrarian University, Baldinyuk Vasyl
Published: June 2022

The article is devoted to the issues of security, support, development of state regulation of foreign economic activity of the agro-industrial complex of Ukraine and economic development of the state. It is determined that foreign trade regulation is carried out to balance the economy and balance of the domestic market of Ukraine, stimulate progressive structural changes in the economy and create the most favorable conditions for attracting our economy to the world division of labor and bringing it closer to market structures. The commodity structure of export-import operations of the agro-industrial sector of the state is studied. The prospects of processing of agricultural products and measures to stimulate the relevant processes are determined. It is proved that the improvement of state regulation requires first of all measures to stimulate the development of biogas production for own needs and long-term export. Subsidies for agricultural milk producers. Encouraging greater use of pellets produced from agricultural waste within the state by setting export quotas. Stimulating the processing of grain crops into finished products with subsequent sale abroad. Excellent visa duties on critical food imports to compensate for the rising cost of relevant products for the population. It is determined that most pellets are exported, which in the context of energy shortages in Ukraine should be regulated by imposing restrictions on export transactions for the sale of solid biofuels. It is proved that the processes of differentiation in stimulating the state through subsidies and soft loans will allow to adapt the production capacity of the agro-industrial complex to the conditions of world markets and increase exports. It is determined that the priority areas of work in the state regulation of the external sphere of agriculture should be: - Attracting foreign investment in agriculture through constant monitoring of proposals from investors, establishing contacts with international financial institutions and international organizations; support of specific investment projects in the field of modernization of agricultural enterprises and providing comprehensive assistance in their implementation; implementation of measures to deepen the activities of executive bodies in the field of practical implementation of the Program of European and Euro-Atlantic Integration of Ukraine; promoting the intensification of foreign economic relations of agro-industrial enterprises and their entry into the foreign market under martial law.
ІНЖЕНЕРНИЙ МЕНЕДЖМЕНТ БЕЗВІДМОВНОСТІ ЗЕРНОЗБИРАЛЬНИХ КОМБАЙНІВ ЗА ТЕХНОЛОГІЇ ТЕХНІЧНОГО ОБСЛУГОВУВАННЯ ПРИ ЗБЕРІГАННІ

Published: June 2022

У статті обговорюються питання доцільності застосування нормативного комплексу інженерного менеджменту за адаптивної технології технічного обслуговування при зберіганні зернозбиральних комбайнів. В основу проведення експериментальних досліджень прийнято робочу наукову гіпотезу, що ефективність машиновикористання зернозбиральних комбайнів в значній мірі залежить від її надійності, зокрема від показників безвідмовності безпосередньо в процесі жнив. При збиранні зернових сільськогосподарських культур необхідно забезпечити працездатний стан комбайнів протягом нормативного агротехнічного періоду. Тому основною характеристичною властивістю зернозбиральних комбайнів і охарактеризовано безвідмовність. Передбачається, що відмови зернозбиральних комбайнів з технічних і технологічних причин призводять до простоїв самих комбайнів і, як наслідок, до втрати частини врожаю зернових. При перевищенні встановленого нормативного агротехнічного терміну збирання збіжжя питомі втрати зернових становлять 0,004…0,006 % за одну годину простою. Аналіз статистичних даних про технічний стан об’єктів на основі експлуатаційних спостережень дозволив виявити ймовірні закономірності і причини відмов. Проведено аналіз результатів експериментальних досліджень зі встановленням чисельних значень показників безвідмовності зернозбиральних комбайнів, а саме, середнє напрацювання на першу відмову, середнє напрацювання на відмову, середня кількість відмов, середній час усунення відмови, коефіцієнт варіації відмов. Представлена графічна інтерпретація залежності показників безвідмовності зернозбиральних комбайнів, а саме, щільність розподілу відмов комбайнів, сумарна кількість відмов в процесі роботи комбайнів, сумарний коефіцієнт готовності зернозбиральних комбайнів. Підтверджено існування впливу зміни середнього напрацювання на відмову в процесі експлуатації комбайнів на показники безвідмовності комбайна. Розглянутий підхід із подібним аналізом дозволяє обґрунтовано висувати вимоги до характеристик технологій технічного обслуговування при зберіганні зернозбиральних комбайнів.

A promising study is the design and improvement of machines for longitudinal cutting of materials with minimal energy costs to perform the technological process of cutting due to the geometry of the cutting tool. The article considers the issues of reducing energy costs for the process of longitudinal cutting when using a knife blade with an arcuate cross-section. The analysis is carried out, the effective method of the analysis of influence of size of a backlash between generators of transporting rollers and size of distance from a vertical axis of rotation of transporting rollers to an edge of a knife blade with an arc-shaped cross section on the total size to determine the necessary settings in the machine of longitudinal cutting for felt, as well as to verify the reliability of analytical and experimental models of the process of longitudinal cutting with a knife with an arcuate cross-sectional shape. To determine the total amount of losses during longitudinal cutting of the material and the number of losses due to friction of the material on the face of a fixed knife with an arcuate crosssectional shape, as well as linear cutting force, a two-factor experiment was conducted for the study model. The obtained regression equations describe the total amount of losses during longitudinal cutting of the material and the number of losses due to friction of the material on the face of a stationary knife with an arcuate cross-section, suggest the adequacy of analytical and experimental models made earlier. Also make the necessary adjustments, namely, to adjust the degree of compression of the material and set the edge of the knife blade relative to the vertical axis of the transport rollers to reduce friction losses on the edge of the knife, which in turn reduces energy costs for longitudinal cutting. Comparing the total values of losses in the longitudinal cutting of the material of a knife with one-sided sharpening and a knife with an arcuate cross-section, allows you to talk about the feasibility of using a knife with an arcuate cross-section, which will reduce energy costs for the process.

Published: June 2022

In the present work, the effect of three insoluble additives densities on reducing the drag of crude oil was investigated. The objective of the present work is to evaluate the effect of the insoluble additive’s densities on their drag reduction efficiency in hydrocarbon flow medium. Three powders with different densities are chosen, namely carbon powder, glass powder, and copper powder, with a density of 1710 kg/m3, 2550 kg/m3, and 8950 kg/m3, respectively. The turbulence flow environment was created in a custom-made rotating disc apparatus with a maximum rotation speed of 300 rpm. To evaluate the effect of the powder density, the particle's size was chosen to be 100 µm. All the solutions were tested at the exact operating conditions with a rotation speed ranging between 200 to 2200 rpm. The experimental results showed a clear effect of the powder density on the drag reduction performance. The glass powders showed the highest drag reduction effect, while the copper and carbon powders were lower. The effect of the degree of turbulence on the drag reduction performance of the powders was clear, where the interaction between the powders and the turbulence structures (eddies) governed the turbulence-suppression efficiency of the additives.
A study of the re-shaping of the backwaters of low-pressure hydrosystems in the lower reaches of lowland rivers
Authors: Baymanov Kenesbay , Baymanov Ruslan
Published: June 2022

The article presents the results of long-term field studies of the re-formation of water courses in the zone of the Takhiatash hydroelectric complex. It was noted that due to low water, for a significant part of the year, the Takhiatash dam worked with fully closed gates in all spans. In these years, the role of regulating the level regime of the shield dam is almost lost, and the end regulators of the main channels are regulated.

The data of comparison of actual expenses, turbidity and back-up at the Takhiatash hydroelectric power plant with the calculated ones are presented. It is proved that sharp fluctuations in the water level in front of the dam and water intake into the channels lead to changes in the hydraulic and alluvial regime of the shield dam and channels. As the analysis of the survey of the riverbed cross-sections in the headwaters of the Takhiatash hydroelectric complex showed, in the initial period of operation, the bottom marks in the upper stream are increasing and the bottom marks in the lower stream are decreasing. Further years of operation (after 1982) were characterized by the stability of the flowing riverbed processes, that each characteristic year has its own level and consumption regime. It is noted that in high-water years there were no difficulties with water intakes, and the main difficulties are associated with the passage of flood flows through the shield dam. In recent years, there has been a rapid rise in the water level in the upper reaches, despite all the open dam gates, shipping locks and water intake structures, which are explained by the influence of the drifted streams on the capacity of the shield dam. It is proved that without any damage to the water intake during the growing season, it is possible to effectively flush the upstream with a constant decrease in the water intake coefficient - Kv < 0.55. Practically, this means for the Takhiatash hydroelectric unit that the flushing flow rate should not be lower than Q ≥ 250 – 300 m3/s.
THE ANALYSIS OF SATELLITE MEASUREMENT OF THE VEGETATION INDEX IN THE FOOTHILL AND PLAIN AREAS OF THE RSO-ALANIA
Authors: Kamenetsky Evgeny , Radionov Anatoly , Timchenko Vasily
Published: June 2022

To analyze the seasonal and long-term variability of the normalized relative vegetation index NDVI, the multichannel MODIS spectroradiometer measurements with a 10x10 km resolution over a 20-year period of time are used. On the territory of the RNO-Alania in the foothill areas and on the plains near the border of the Stavropol Territory five geographical locations are selected, located at different distances from the Northern spurs of the Caucasian Ridge. For each geographical location the sets of time series are obtained for: 16-day NDVI composites, daily temperature at an altitude of 2 m and precipitation for the 20-years period from 01.01.2000 to 31.12.2019. By calculating the integral characteristic for an annual period of time for every location, the series of 20 annual values are obtained. According to the obtained series, three 20-year trends are built and the trend parameters of a first-order polynomial are calculated using the least squares method.

The NDVI trend slope switch is observed in the Mozdok-Russkoe location for transition from the time period 2000–2009 to the period 2010–2019, when the slope changes from positive to negative. Similar NDVI trend slope switches are observed for other locations. This may be due changing the level of soil moisture over time, taking into account mainly the downward trends in precipitation. The trend slope of the NDVI integral characteristic 5–15 % increases with the increasing of the distance from the mountain ridge. The temperature trends for all locations are ascending, that indicates an average increase of the number of warm days from year to year. At the same time, the maximum temperature during the summer period does not significantly increase. The trend of the integral characteristic for the amount of precipitation is mainly downward. However, its specific values have a fairly large spread, which means that the amount of precipitation varies significantly from year to year. In addition, the amount of precipitation decreases with distance from mountain ridges.

These factors should be taken into account when choosing agricultural products for cultivation and planning additional land-reclamations in the flat and foothill areas on the south of the Russian Federation.

Published: June 2022

The article considers the state of emergency in Ukraine in connection with the large-scale invasion of the russian federation, in particular, its impact on the Ukrainian education system. This issue requires a comprehensive analysis of the functioning of the education system in the context of martial law, which determines the relevance of this article. It has been established that under martial law conditions, the key objectives of Ukraine’s educational policy were to ensure the organization of the learning process, and thus the provision of educational services to students in Ukraine, as well as to internally displaced and refugee children. The rights and needs for protection, including the protection of the rights of children and youth to education, were emphasized. Analysis of literary sources and legal framework confirmed that russia’s full-scale invasion of Ukraine grossly violates international law and the UN Charter, and thus undermines European and global stability and security (namely, Safe Schools Declaration). The obligations of countries of the world to protect pupils, students, teachers, schools and universities during armed conflict and to support the continuation of education throughout the war were studied. The article focuses on the actions of the Government of Ukraine, international organizations and countries hosting Ukrainian refugees to return children to school, providing psychosocial support, educational opportunities and non-formal education. It is noted that Ukrainian refugees are involved in the educational process through schooling; the organization of free language courses for children and adults; access to online educational resources, including the inclusion of education and training systems in the EU, and recognition of qualifications of Ukrainian students for access to higher education and the labor market. At the same time, the emphasis is placed on the fact that the mental health and psychosocial support of all participants in the educational process play an important role during the war. A number of initiatives and assistance programs of the international community to ensure the continuity of educational services both in Ukraine and abroad are outlined. It is substantiated the conclusion that the Ukrainian Government has made maximum efforts to ensure the urgent needs of the population, among which the right to education takes the leading place. Prospective directions of further research can be studies of the international experience of adaptation to the educational process of students and teachers in EU countries.

Interaksi Sosial merupakan sebuah kegiatan manusia dalam berhubungan dengan manusia lainnya, kegiatan ini terjadi saat manusia melakukan kontak sosial dan komunikasi. Jenis dalam melakukan komunikasi melalui media yang bisa digunakan salah satunya menggunakan media komunikasi bahasa isyarat tangan. Terkadang masyarakat belum paham akan bahasa isyarat tangan yang disampaikan oleh masyarakat tuna rungu, oleh karena itu diperlukan sebuah sistem pengenalan guna membantu keberlangsungan kedua masyarakat tersebut. Pengembangan sistem pendeteksi Indonesia Sign Language berbasis web diharapkan dapat menjadi jembatan antara masyarakat non tuna rungu dengan masyarakat tuna rungu. Sistem pada web ini menggunakan kerangka kerja pada bahasa pemrograman Python dengan pemanfaatan Microframework Flask sehingga dapat memudahkan dalam membangun sistem aplikasi serta tak lain karena fungsionalitasnya berbasis website sehingga dapat mudah untuk melakukan akses fitur-fitur pada sistem klasifikasi citra masukan gambar dan sistem ini dapat diakses dari berbagai macam platform seperti Windows, Android, dan iOS. Sistem ini dirancang menggunakan bantuan kecerdasan buatan yakni algoritma jaringan syaraf tiruan untuk melakukan prediksi klasifikasi dan prediksi lokalisasi bahasa isyarat tangan. Hasil dalam penelitian ini adalah sebuah aplikasi pendeteksi bahasa isyarat yang mampu mendeteksi berbagai macam bentuk dengan jumlah 26 kelas bahasa isyarat dari huruf alfabet A hingga Z.

Anjing merupakan salah satu hewan yang sering dijadikan hewan peliharaan bagi manusia. Seringkali pemilik tidak mengetahui penyakit kulit yang diderita oleh anjing peliharaan yang dapat menyebabkan menjadi parah ataupun kesalahan fatal bahkan kematian pada anjing peliharaan. Adanya sistem ini diharapkan dapat membantu pemilik dan dokter hewan untuk mengetahui mengenai diagnosa awal terhadap penyakit kulit yang diderita oleh anjing peliharaanya sehingga mendapatkan penanganan yang tepat setelahnya. Penelitian ini akan menerapkan Case Based Reasoning pada sistem diagnosis penyakit kulit anjing dengan menerapkan metode Jaccard Coefficient (JC) dan Simple Matching Coefficient (SMC). Kedua metode digunakan untuk membandingkan diantara kedua metode ini, hasil akurasi mana yang mendekati sempurna akan digunakan untuk mendapat hasil terbaik dalam pengambilan keputusan. Data yang digunakan berupa gejala-gejala dari penyakit yang ada. Hasil diagnosa didapatkan dari gejala yang telah dimasukkan oleh pengguna yang akan mencari kemiripannya dengan kasus lama dengan menghitung nilai similaritas menggunakan metode Jaccard Coefficient dan Simple Matching Coefficient. Nilai similaritas yang paling mendekati 1 akan dijadikan sebagai solusi dari kasus baru. Apabila nilai similaritas < treshold, maka kasus baru akan dievaluasi kembali untuk mendapatkan solusi. Setelah proses tersebut, kasus baru akan dimasukkan kedalam basis pengetahuan untuk digunakan lagi sebagai pembanding dalam proses diagnosa selanjutnya. Hasil pengujian sistem mendapatkan nilai akurasi sebesar 93,75%, nilai precision sebesar 93,75%, dan nilai recall sebesar 100%. Sementara itu untuk perbandingan metode, dibuktikan bahwa metode Simple Matching Coefficient lebih baik dengan perbandingan akurasi yang mana metode Simple Matching Coefficient mendapat nilai akurasi 93,75%, sementara metode Jaccard Coefficient mendapat nilai akurasi sebesar 87,5%.

Balita merupakan usia emas atau acuan dalam proses pertumbuhan dan perkembangan manusia, faktor penentu pertumbuhan individu pada periode pertumbuhan berikutnya. Beberapa faktor yang umumnya mempengaruhi status gizi balita, diantaranya berat badan, tinggi badan balita, faktor penghasilan keluarga, faktor intensitas ASI, jumlah anak dalam satu keluarga, pendidikan dan pengetahuan ibu mengenai pertumbuhan balita, serta akses kesehatan dapat juga mempengaruhi status gizi balita. Sebuah sistem dapat dibangun untuk menciptakan sebuah aturan keputusan yang dapat digunakan untuk mengidentifikasi status gizi pada balita. Dengan melalui beberapa tahapan, diantaranya dimulai dari pengumpulan data, perhitungan data latih untuk memilih atribut akar atau parent node, selanjutnya membuat cabang untuk masing-masing kategori, sehingga menghasilkan suatu pohon keputusan yang sesuai. Pohon keputusan yang dibangun memiliki tingkat akurasi sebesar 0,85, nilai precision sebesar 0,2982456 serta nilai recall didapatkan sebesar 0.3146. Namun hasil tersebut dapat berubah dalam setiap pemilihan data uji dan data latih. Dalam artian data uji dan data latih yang akan digunakan dalam sistem ini mempengaruhi hasil dari pengukuran kinerja algoritma dan hasil uji coba sistem.
