Further - determination of the spectrum of their probable purpose, impact on the features and indicators of the blast furnace process, as well as justification of rational ways of their preparation and use. 3. Rational shares of substitution of traditional raw materials and fuels with secondary materials in the blast furnace process are substantiated, the use of which will not reduce the quality of pig iron and will not increase the specific consumption of coke. Their influence on physicochemical and heat-gas-dynamic processes, which is reflected in the characteristic zones of the blast furnace, has been studied. 4. The optimal technological schemes and recommendations for the methods of introduction and rational specific consumption of innovative materials based on man-made wastes have been determined, which will ensure the maximum level of use of their useful properties in the material and thermal balances of the blast furnace process. 5. The technological and environmental advantages of introducing into the blast furnace process a monomaterial, the composition, physicochemical features and spectrum of purpose of which are formed by heat treatment of a mixture of man-made industrial waste, are evaluated and their prospects as a substitute for the corresponding part of pulverized coal fuel (PCF) and fluxes are determined.

For the first time, a resource-efficient and results-efficient approach has been used to assess the efficiency of the use of materials based on secondary resources of metallurgical and plant origin, based on an integrated combination of the results of thermodynamic forecasting, physical modeling and taking into account the provisions of the exergical methodology for assessing the energy efficiency of the objects of study. Methodological bases have been developed for the selection of rational schemes for the introduction of complex materials based on secondary materials into the blast furnace charge and in the air blast flow to stabilize gas-dynamic conditions in the charge layer, intensify recovery processes with a decrease in the specific consumption of coke per ton of liquid pig iron. The regularities of the influence of the composition and dispersion of secondary resources on the gas-dynamic and thermal parameters of blast furnace smelting have been revealed, which makes it possible to increase the accuracy of predicting the furnace course. It has been proved that the use of materials based on secondary resources of mineral raw materials and fuels can provide the effects of increasing the energy efficiency of pig iron production and reducing the environmental burden, which meets the requirements of sustainable development and the concept of "green metallurgy".

(European University Press, ISMA University of Applied Sciences, Riga, Latvia, 2023) Korkhina, Inna A.; Petrenko, Vitalii O.
ENG: The commercial real estate market in Ukraine has changed significantly over the past few years. This article focuses on commercial real estate, in particular, shopping and entertainment centers (SECs). Ukrainian SECs have suffered significant losses due to the COVID-19 pandemic, and then some more suffered serious damage during the full-scale war. However, most of the SECs have resumed or are resuming their operations, and new SECs are being unfrozen. The unstable situation in the country, massive population movements within the country and the departure of many Ukrainians abroad make the management of SECs to revise their development plans and marketing strategies. Modern marketing strategies for promoting SECs require the use of innovative tools. This paper considers the problem of using special software for marketing automation. The authors have selected the most well-known marketing automation platforms for any project and conducted a comparative analysis of them.
