Understanding the Impact of ESG on Brand Trust and Customer Engagement
Authors: Tripopsakul Suchart , Puriwat Wilert 
Published: May 2023

Businesses all over the world are paying more attention to environmental, social, and governance (ESG) investment initiatives. However, few studies discuss its impact on customers' attitudes and brand perception. The purpose of this research was to verify the causal relationship between ESG initiatives, brand trust, and customer engagement as perceived by customers in Thailand. An online survey was requested, and a total of 175 participants were chosen for data analysis. To conduct statistical analysis, partial least squares structural equation modeling (PLS-SEM) was used with the SMARTPLS3 program. The findings showed that the three elements of ESG have significant positive effects on brand trust and customer engagement. The result of the mediation analysis revealed that brand trust significantly mediates the causal association between the three elements of ESG and customer engagement. The environmental pillar of ESG (B = 0.527) has the largest impact on brand trust, followed by the social (B = 0.315) and governance (B = 0.239) pillars. On the one hand, the strongest predictor of customer engagement is the social pillar of ESG (B = 0.594), followed by the environment (B = 0.513) and the governance (B = 0.181) pillars. Additionally, it was established that the value created by businesses’ ESG initiatives could have a direct effect on brand trust and customer engagement. Therefore, the study’s objectives are to increase the diversity of scholarly perspectives on ESG and to offer valuable marketing implications for companies that desire to implement ESG strategies.

Diallyl trisulfide induces pro-apoptotic autophagy via the AMPK/SIRT1 signalling pathway in human hepatocellular carcinoma HepG2 cell line
Authors: Sun Shuoshuo , Liu Xiyu , Wei Xiao , Zhang Shaohong , Wang Weimin 
Published: May 2023

Background: Liver cancer is associated with a high mortality rate worldwide. Hepatocellular carcinoma (HCC) constitutes a large proportion of primary liver cancers, and most of its alterations currently remain untreatable. Diallyl trisulfide (DATS), the main chemical constituent of allicin, affects tumour development by regulating cell apoptosis. Allicin-induced autophagy could contribute to apoptosis in HepG2 cells. We rigorously examined the autophagy-related mechanism of allicin-induced apoptosis in HepG2 cells. We treated HepG2 cells with DATS to explore the effect of DATS on pro-apoptotic autophagy in HepG2 cell lines and examine its specific molecular mechanism.
Methods: HepG2 cells were treated with various concentrations of DATS for 24 and 48 h. Subsequently, cell viability was measured using the cell counting kit-8 (CCK-8) assay and cell clone formation assay. The HepG2 cell apoptosis was measured using Hoechst 33258 staining and western blotting. Autophagy and the AMP-activated protein kinase (AMPK)/NAD-dependent deacetylase sirtuin-1 (SIRT1) signalling pathway were detected using western blotting.
Results: Our results indicated that DATS inhibited HepG2 cell growth. Moreover, the ability of DATS to promote apoptosis in HepG2 cells increased with increasing concentration. We verified the phenomenon of DATS-induced autophagy in HepG2 cells and demonstrated that DATS treatment upregulated the protein expression of LC3-II/I. By measuring the expression of potential autophagy stimulators, we documented that DATS could induce pro-apoptotic autophagy by activating the AMPK/SIRT1 signalling pathway.
Conclusion: DATS induced pro-apoptotic autophagy via the AMPK/SIRT1 signalling pathway in the human HCC HepG2 cell line. Our findings further implicate allicin as a potential therapeutic agent against liver tumours in clinical settings, providing a basis for combining allicin with an autophagy agonist for treating liver cancer.

A ruptura aguda do tendão de Aquiles é uma lesão frequente dos membros inferiores e existe controvérsia em relação ao tratamento ideal. Diversos métodos estão descritos na literatura, dentre eles, tratamento conservador, reparo aberto e cirurgia minimamente invasiva. O reparo aberto está associado a maior índice de complicações no sítio cirúrgico enquanto as técnicas minimamente invasivas apresentam risco aumentado de lesão iatrogênica do nervo sural. Alguns dispositivos foram desenvolvidos para reduzir as complicações das primeiras técnicas percutâneas descritas. Apresentamos uma técnica para reparo das lesões agudas do tendão de Aquiles de maneira percutânea utilizando materiais simples disponíveis na maioria dos centros cirúrgicos, sem necessidade de instrumental especial. Associado a essa técnica, adotamos protocolo de reabilitação funcional precoce, que já provou ser vantajoso na recuperação das funções do paciente.
REGIONAL METAMORPHISM AND STRATIGRAPHY OF THE BASEMENT OF THE UKRAINIAN SHIELD
Authors: Kyrylyuk V.P. , Gaiovskyi O.V. 
Published: May 2023

Stratigraphic complexes of the Lower Precambrian are everywhere metamorphosed. Therefore, the stratigraphic subdivision of the Lower Precambrian has always been inextricably linked with the study of metamorphism. For some time, the degree of metamorphism of the complexes was even used as an indication of their relative age. With the beginning of the use of isotopic dating, this sign was not confirmed, after which the degree of metamorphism was no longer taken into account in the stratigraphic dismemberment of the shields basement. The degree of metamorphism of the complexes was no longer taken into account for a long time when compiling official stratigraphic schemes of the Precambrian of the Ukrainian Shield, which, in the opinion of many geologists, led to distortions of the real stratigraphy of the basement of this region.
The authors of the article believe that the degree of metamorphism can still be used in the development of the stratigraphy of the Ukrainian Shield and, above all, in the stratigraphic study of individual megablocks. The possibility of such use of metamorphism is considered in the cycle of publications. This is the second article in the cycle. The first article describes the stratigraphy and metamorphism of all megablocks of the Ukrainian Shield. A number of conclusions have been made about the regularities of the manifestation of metamorphism. It is shown that older stratigenic complexes in each of the megablocks are characterized by higher temperature metamorphism. This pattern provides a basis for establishing the relative stratigraphic sequence of complexes within individual megablocks based on the degree of their metamorphism. At the same time, the distinctive features of the composition and metamorphism of the stratigenic complexes, according to the authors, are a reflection of the successive stages of the geological development of the Ukrainian Shield in the Early Precambrian and can serve as the basis for compiling of the regional stratigraphic scheme on a historical and geological basis. In this second article of the cycle, modern approaches to the geochronological periodization of the Precambrian are considered: a) geochronometric, adopted for the International “The Geological Time Scale” and b) historical-geological, which is the basis of the “General Stratigraphic Scale of the Lower Precambrian of Russia”. The current “Correlation Chronostratigraphic Scheme of the Early Precambrian of the Ukrainian Shield” is based on the geochronometric approach, which the authors, like many other researchers, consider unacceptable for practical use. The article proposes a variant of the regional stratigraphic scheme of the Ukrainian Shield on a historicalgeological basis, compiled at the level of complexes, which in the final version of the scheme can be divided into series and suites.

Signal processing in intelligent control systems for low-visibility and low-mobility air units
Authors: Solonskaya S. , Zhyrnov V. 
Published: May 2023

It is proposed to improve the effectiveness of survey radars in detecting and recognizing low-visible and slow-moving air objects by creating special (virtual) space-time images for accumulating both energy and semantic components of signal information using the mathematical apparatus of algebra of finite predicates. It is shown how this approach can be used to detect and recognize slow-moving aircraft, which can be both in flight mode and in hang mode. Such signaling information will be accompanied by different semantic distinctive features: a sign of a trace and sign of the signal repetition.

Authors: Synkovska Olena , Ihnatenko Andrii , Nazarenko Iryna 
Published: May 2023

Abstract. Problem. Steel-concrete cylindrical load-bearing elements are rational for reducing material intensity of individual elements and systems as a whole in construction. External sheet reinforcement of cylindrical elements, which is in the form of clamp, simultaneously performs the power, protective and technological functions. The clamps in steel-concrete cylindrical load-bearing elements restrain the movement of concrete in the transverse direction and lead to the gain in concrete strength among other. The concrete in the middle of the shell-clamp, in turn, increases its stability. Goal. The purpose of these theoretical researches is to determine the load-bearing capacity increase coefficient of a steel-concrete cylindrical load-bearing element based on the fundamental theories and criteria of material resistance and the theory of elasticity. Methodology. Research was performed using the analysis of scientific literature, systematization and unification of various theoretical methods and criteria for the strength of materials and the stress-strain behavior of individual elements and the structure as a whole. Results. Theoretical calculations to determine the load-bearing capacity increase coefficient of a steel-concrete cylindrical element made by enclosing a concrete core in a steel clamp are presented on the basis of the combined fundamental theories and criteria of material resistance along with the theory of elasticity. Originality. The scientific novelty of the work consists in the fact that specific fundamental theoretical methods and criteria for assessing strength and determining the stress-strain behavior of structural elements were comprehensively analyzed and systematized, taking into consideration current regulatory requirements. Practical value. The presented results of the work are significantly different from most of the presented methods in the direction of calculating the stress-strain behavior and determining the load-bearing capacity of steel-concrete cylindrical load-bearing elements. Firstly, this would enable scientists to look at the problem of calculating such load-bearing elements from a new angle in further research, and secondly, it would accelerate the possibility of rational using of steel-concrete cylindrical load-bearing elements in all directions of construction.

Authors: Bondarenko Dmytro , Ushakova Iryna 
Published: May 2023

Abstract. Problem. The operation of transport systems of a large city must ensure a continuous flow of passengers. The subway occupies a special place in the city's transport system. The constant increase in the loading of the subway not only worsens the conditions of passenger transportation, but also shortens the service life of the rolling stock and negatively affects the reliability of its operation. In the future, this may cause failures of the rolling stock, which means work failures. The main factor in the development of subway systems is passenger traffic, which determines the development of the subway network, the capacity of technical equipment, the number of vehicles, the size of depots and vehicle repair plants, and the time of repair with the least economic losses. Thus, one of the urgent tasks of the functioning of transport systems is the creation of an automated system of mass passenger service, in particular in the subway. Goal. The tasks of this study are the analysis of the subject area, the design of the information system according to the task, the selection of the necessary tools for this development, and the methods of software implementation. Analysis of passenger flows using an automated system will allow to solve many problems of design, operation, and planning of metro work, will allow to reduce the time for passenger service and optimize passenger flows. Methodology. Research methods are the methods of mass service systems. Results. The creation of a functional model will make it possible to develop a software product for the analysis and assessment of public transport passenger traffic. Originality. Practical value. The software product created on the basis of the developed functional model will enable the user not only to analyze, but also to optimize the work of both existing and future metro stations.

Authors: Zadachyn Viktor , Frolov Oleg 
Published: May 2023

Abstract. Problem. The problem of building models and methods of forecasting the daily need for urban water is considered. Much more attention needs to be given to forecasting methods if utilities are to make decisions that reflect the level of uncertainty precisely in future daily demand forecasts. Daily water consumption, unlike annual and monthly water consumption, is much more highly dependent on chance. Goal. The main goal of this paper is to obtain enough accurate forecasts of daily urban water consumption. Method. An algorithm for calculating the urban daily water demand forecast based on the concept of same-type days of water demand for previous years has been suggested. Scientific novelty. The originality of the method lies in the fact that it does not use neural network models, but still makes it possible to obtain enough accurate forecasts of daily urban water needs. Results. The presented algorithm for calculating the urban daily water demand forecast has been implemented in the form of a software package and has been tested for many years in real-life conditions. The average absolute percentage error of the daily forecast of urban water demand for one month does not exceed 5%. Practical significance. The practical value of this work lies in the fact that the presented software complex for calculating the forecast of the city's daily water demand can be used in the information services of city utility companies to make operational and tactical decisions regarding the provision of water supply services to the population.

Authors: Krasnikov Sergey 
Published: May 2023

Annotation. Problem. The natural frequencies and features of the natural forms of the turboset-foundation-base system near the operating frequency are considered. Goal. The aim of the work is to study the natural frequencies and modes of natural oscillations of the turboset-foundation-base system near the operating frequency range to assess the vibrational state of the system and determine the causes of increased vibrations. The object of the study is the system of turboset-foundation-base. The system consists of a single reinforced concrete foundation on which a steam turbine and a generator are installed. The subject of the study is the natural frequencies and forms of natural oscillations of the turboset-foundation-base system. Methodology. The study was carried out by oscillation methods and the finite element method. The use of original methods developed directly by the author for constructing models of complex machine-building systems should also be mentioned. Results. As a result of the research, three-dimensional finite element models of low-pressure cylinder bodies, the foundation and the entire turboset-foundation-base system were built. The conducted study allows us to draw a conclusion regarding the causes of an increased level of vibration near the operating frequency and directions for their prevention. Originality. Regarding the methods of constructing a model of the turboset-foundation-base system, their uniqueness should be noted. The features of the applied modeling method make it possible to take into account the variable interaction between low-pressure cylinder bodies and the foundation. Fixpoints are also taken into account. Previous studies of the turboset-foundation-base system did not allow us to determine the nature of the oscillation modes near the operating frequency. Practical value. The results of the work relate to direct practical application. As a result of the work, conclusions were made about ways to increase the vibration reliability of the turbine unit-foundation-base system and further research directions.
DESCRIPTIVE DEVELOPMENT OF VERBAL ATTENTION IN OLDER PRESCHOOL CHILDREN WITH LOGOPATHOLOGY
Authors: Bielova Olena 
Published: May 2023

The purpose of this study is to identify the current state of formation of verbal attention of older preschool children with logopathology, which affects their speech readiness for learning in general secondary education institutions. Research task: theoretical analysis of scientific sources on the problem of study; specify research methods and parameters revealing the level of verbal attention; carrying out a comparative analysis of the results of the study of older preschool children with logopathology and normotypical psychophysical development. Research methods are methods with tasks aimed at studying the semiotic and psychological components of speech readiness, in the criteria of which the parameters for evaluating the properties of verbal attention (selectivity, stability, distribution, concentration, switching, volume) are outlined. The results of the experimental study give a clear idea that there are significant differences between the groups of children with speech pathology and those with normotypical psychophysical development regarding the formation of verbal attention of the psychological component of speech readiness: children with speech pathology have insufficiently developed properties of verbal attention, which prevents them from listening carefully to tasks (concentration), focused on it for a long time (persistence), performed other exercises in parallel (distribution), worked on several verbal tasks during the lesson (volume), switched to other actions (switching), focused on a specific task (selectivity). The inability to concentrate attention on educational activities leads to the impaired perception of speech information, its memorization, representation, reflection and verbal reproduction. Research materials indicate the unformed readiness of this category of children to integrate into the conditions of general secondary education institutions.
Keywords: verbal attention; selective attention; stability of attention; distribution of attention; the concentration of attention; switching of attention; amount of attention; children of older preschool age; speech disorder.
