APPLICATION OF DIGITAL TECHNOLOGIES IN THE FIELD OF ANIMAL HUSBANDRY

In the modern world, the use of digital technologies and automation in agriculture is becoming increasingly widespread. According to the United Nations, by 2050 the world's population may reach 9.7 billion, and in 2080 it will peak at 10.4 billion people, so the demand for food will grow significantly. One of the possible solutions to meet this demand is the development and active implementation of digital technologies in animal husbandry. Modern digital technologies are transforming the industry and providing new opportunities for farmers to increase efficiency and productivity while minimizing their environmental impact. These technologies are also used to optimize farmers' work. One of the industries that benefits most from automation is precision animal husbandry. Precision animal husbandry is agriculture that uses technology to monitor and manage livestock with efficiency and sustainability. Using artificial intelligence-based automation, farmers can collect data about their livestock, such as health and nutritional information, in real time. This data can then be used to make informed decisions about animal care and management. Thanks to digital technology, farmers can improve and optimize their livestock management practices. For example, the health and well-being of animals can be monitored using drones, cameras, and AI sensors that can alert humans to potential problems. In addition, artificial intelligence can be used to make decisions about breeding and feeding strategies by tracking the performance of individual animals. Digital technologies are also being introduced to improve the efficiency of the farm itself. The use of AI-enabled robots can automate certain tasks, such as milking and feeding, allowing farmers to focus on other activities. The use of resources such as water and energy can also be optimized with AI, which can help mitigate the environmental impact of agriculture. Finally, the use of robots on farms helps to improve product traceability. AI-driven sensors can monitor the condition and location (and even identify) of animals to ensure product quality and safety, and increase the sustainability of livestock production.

Implementation of Digital Technologies in the Tax Sphere: Foreign Experience and Prospects for Ukraine in Combating the Shadow Economy

Digital technologies as a driver of resilience and institutional transformation: The case of Ukrainian agroholdings

Abstract The present paper explores how implementation of digital technologies (DTs) assists firms in transition economies in addressing weaknesses of the institutional environment surrounding them, in particular via establishment of collective governance systems. Based on case studies of three large-scale agroholdings operating in Ukraine, the paper aims to fill the research gaps with regard to the following: motivation of the firm to initiate DT-enabled collective governance systems; the rules these systems are based on; and the reasons behind the firm’s choice of a particular governance mode – closed, shared or open – for these systems. The findings generally support the institutional theory argument that complex technology enables coordination of exchange relationships not only within but also outside firm boundaries. At that, the choice of a governance mode between closed, shared or open institutional infrastructure is likely to depend on the firm’s ownership concentration, corporate transparency, availability of resources and social embeddedness.

Evaluate and identify the competencies of the future workforce for digital technologies implementation in higher education

In recent years, both information technology (IT) labor demand and IT job characteristics have been significantly influenced by the advent of Industry 4.0 (I4.0) and the digital age. The higher education sector is expected to upgrade itself with such progress and train graduates capable of meeting the new industry requirements. However, due to the present demand gap, universities are seeking to identify the skills new digital workers are expected to have. As we live in the digital age, the literature has failed to address the questions of the consequences for individual workers adequately. Considerable scientific efforts should be made to design certain curricula and training programs that could nurture digital competencies (DC). There is a need to construct an inclusive framework of the term. In addition, different options exist for studying the DC of the workforce in relation to human resources management (HRM). The current paper attempts to fill the gap by developing an integrated decision-making framework. The paper aims to introduce an innovative discrimination measure and discuss its elegant properties. A Measurement of Alternatives and Ranking according to the COmpromise Solution (MARCOS) framework for evaluating the MCDM problem on a fuzzy set has been developed based on it. On the other hand, the new methodology of the PF-entropy-RS weight technique is used to compute the criteria weights or significance degrees of criteria. Then, the MARCOS method is a new elegant approach to handle the MCDM problems. Thus, in this study, we have developed a new approach to the multi-criteria decision-making (MCDM) method using the PF-entropy-RS and PF-MARCOS methods and further implemented for the evaluation of the competencies of the future workforce for digital technologies implementation in higher education. It helps to calculate the objective/subjective weights of criteria to evaluate the competencies of the future workforce for digital technologies implementation in higher education; then, the approach is used to assess the preferences of higher education institutes over different competencies of the future workforce for digital technologies implementation in higher education. An empirical case study is carried out in this paper for the evaluation of the most important competencies of the future workforce for digital technologies implementation in higher education. In addition, to evaluate the performance quality of the proposed framework, this study also involves some comparison and sensitivity analyses. This study found that data and information processing has emerged as the most important competencies of the future workforce for digital technologies implementation in higher education. The ability to interact with modern interfaces is the second most important competency of the future workforce for digital technologies implementation in higher education. In conclusion, the workforce responsible for implementing digital technologies in higher education will significantly impact students’ learning experiences. As technological advancements continue, higher education institutions will require skilled professionals with diverse digital expertise to manage and integrate these technologies successfully.

Двухуровневый цифровой экологический мониторинг городов горно-металлургического комплекса Урала

Introduction. The main approach to the development of modern cities is an approach based on the balance of social, economic, and environmental subsystems, within the framework of which plans to achieve sustainable growth are implemented. In the era of digitalization, the most important condition for effective environmental management is the use of advanced tools for analyzing data obtained during the environmental monitoring procedure. Materials and methods. The methodology for monitoring the state of various components of the environment involves a number of sequential operations. The first stage of the study (obtaining a priori information) pursues the goal of creating a landscape-geochemical basis on which information about typical elementary landscapes reflecting the structure of the area is placed. The second stage includes obtaining operational information about the state of selected environmental components using field and laboratory methods. At the third stage, desk processing of information is carried out. Results. The structure of environmental monitoring can be divided into levels in accordance with the degree of detail of the tasks assigned to it. The most appropriate division of environmental monitoring in cities for the conditions of the Urals seems to be the following levels: a) local, examining the state of the environment as a whole in the city or on the border of the sanitary protection zone of an enterprise and b) detailed, examining the state of the environment from the impact of waste disposal facilities. Discussion. In the field of environmental monitoring, a digital database should be created at the local and detailed levels, with the help of which it is possible to conduct analysis and further forecast the state of the environment, with the subsequent development of environmental measures. Environmental monitoring within cities with a mining and metallurgical complex must be carried out comprehensively, including the atmosphere, surface water, soil, snow cover, groundwater and vegetation. Conclusion. Thus, the proposed environmental monitoring system is characterized by high environmental and economic efficiency, which meets the requirements of sustainable development at the present stage. Resume. For the cities of the mining and metallurgical complex of the Urals, it is necessary to conduct two-level environmental monitoring with the development, implementation and dissemination of digital technologies in the environmental sphere. Environmental monitoring within cities with a mining and metallurgical complex must be carried out comprehensively, including the atmosphere, surface water, soil, snow cover, groundwater and vegetation. Conducting local monitoring in the territory of influence of the enterprise and detailed monitoring in the zone of influence of waste disposal facilities presupposes the presence of stable observations in the space-time interval and a stable ingredient composition. The instability of observations leads to deterioration of the analysis, which reduces the quality of the forecast of the situation and recommendations for preventive measures. Suggestions for practical applications and directions for future research. The research results can be useful in the formation of a data bank on the state of the environment for the development and adoption of environmental measures with high environmental and economic efficiency at industrial facilities of the mining and metallurgical complex.

Numerical analysis of the behavior of molten pool and the suppression mechanism of undercut defect in TIG-MIG hybrid welding

In order to investigate the multi-coupling transport phenomena in TIG-MIG hybrid arc welding, a three-dimensional model including droplet and molten pool was established. An innovative distribution pattern of arc heat and force that adapted to the evolution of molten pool surface was proposed, achieving a unified distribution of "arc current density-arc pressure-electromagnetic force-arc heat". The effect of TIG arc on molten pool behavior and undercut defect was quantitatively analyzed by comparing TIG-MIG hybrid welding with traditional MIG welding. The results showed that the electromagnetic repulsion between the two arcs with opposite currents increased the aspect ratio of the hybrid arc heat and force distribution. It led to a long and narrow gouging region, where the promoting effect of inertial force on the undercut was weakened by arc pressure and hydrostatic pressure. The liquid metal with a lower cooling rate had sufficient time to fully fill the weld toe and suppressed undercut. Sensitivity and dimensional analysis illustrated that the TIG-MIG hybrid arc eliminated undercut by reducing the inertia force, adjusting the arc pressure distribution, and enhancing the hydrostatic pressure. The groove sizes was predicated based on molten pool characteristics, including the stress state of liquid metal, morphology, and fluid flow patterns. It revealed the quantitative relationships among welding parameters, behavior of molten pool, and weld bead formation, promoting the implementation of digital twinning technology in the manufacturing industries.
