Authors: Sahoo Sushil , Das Ashes , Samanta Sourav , Goswami Shankha
Published: June 2023

The relationship between Sustainable Development (SD) and Global Warming (GW) is a critical issue that has implications for the future of our planet. This research paper explores the ways in which SD can help address GW and the ways in which GW can impact SD. The paper argues that SD can help mitigate the negative impacts of Climate Change (CC) by promoting the use of renewable energy, reducing waste and pollution, and promoting sustainable land use practices. However, achieving SD in the context of GW requires a holistic approach that balances economic, social, and environmental concerns. Furthermore, the paper discusses the ways in which GW can impact SD by disrupting ecosystems, reducing the availability of natural resources, and increasing the risk of natural disasters. It also highlights the importance of adopting policies and practices that address the root causes of GW, while promoting SD practices that benefit all people and the planet. The research paper concludes that achieving SD and addressing GW are two interconnected issues that must be prioritized to ensure a healthy and prosperous future for all people and the planet. It calls for urgent action and collaboration among governments, businesses, and individuals to adopt SD practices and reduce Greenhouse Gas Emissions (GHGE).

Authors: Paunović Ivan , Mamula Tatjana
Published: June 2023

The purpose of this study is to extend previous research on brand innovation by uncovering the process of family winery branding in relation to the new product launch in the VUCA market on the case of three Serbian wineries. The study deploys qualitative oriented and empirical approach in presenting a multi-case study. Three semi-structured telephone interviews were conducted with owners and/or managers in these three wineries. The results demonstrate that all three family wineries are offering high-end product for the domestic market with smaller one still experimenting with strategic direction of innovating for high-end market while the two larger ones putting focus either on autochthonous grape varieties with eye-cathicng labels or authentic brand identity with strong storytelling. Another important aspect identified is the frugal nature of product launch in the family wineries due to limited resources. The paper presents is among only few studies on new product development in wine business literature.

Authors: Brzaković Stefan , Brzaković Aleksandar , Đurđević Sanja
Published: June 2023

Studies have shown that an organization's human resources should be effectively attracted, developed, motivated, managed, and valued to sustain a competitive edge in the market. Organizations must take care of the strategy of scale, the diversification of activities, the allocation of resources, the orientation towards the buyer, value chains, change management, innovations, and the strategic renewal of the organization itself in order to maintain their competitive advantage(s) and ensure their survival. This paper is aimed at determining whether the level of the factors for creating the value of the organization and the level of the competitive advantage of the organization actually affect or do not affect the level of human capital in the organization. Based on the research conducted in the paper, it can be concluded that the level of human capital in the organization increases simultaneously with the increasing of the level of the factors for creating the value of the organization and the level of the competitive advantage of the organization.

Authors: Hulku Sakıne , Devec Ömür
Published: June 2023

N this paper, we define the Tribonacci-type balancing numbers via a Diophantine equation with a complex variable and then give their miscellaneous properties. Also, we study the Tribonacci-type balancing sequence modulo m and then obtain some interesting results concerning the periods of the Tribonacci-type balancing sequences for any m. Furthermore, we produce the cyclic groups using the multiplicative orders of the generating matrices of the Tribonacci-type balancing numbers when read modulo m. Then give the connections between the periods of the Tribonacci-type balancing sequences modulo m and the orders of the cyclic groups produced. Finally, we expand the Tribonacci-type balancing sequences to groups and give the definition of the Tribonacci-type balancing sequences in the 3-generator groups and also, investigate these sequences in the non-abelian finite groups in detail. In addition, we obtain the periods of the Tribonacci-type balancing sequences in the polyhedral groups (2, 2, n), (2, n, 2), (n, 2, 2), (2, 3, 3), (2, 3, 4), (2, 3, 5).

Published: June 2023

Introduction/Aim: Vitreoretinal diseases can lead to permanent vision loss. The aim of our study was to present the frequency, demographics and treatment options of the patients hospitalized and treated at the tertiary healthcare Department of Vitreoretinal Surgery and Eye Trauma in a two-year period. Material and Methods: The retrospective study was conducted at the Clinic for Eye Diseases, University Clinical Center of Serbia in Belgrade, Serbia in the period between November 30, 2020 and December 4, 2022. |Data on demographics, seasonality and treatment methods were collected from "Heliant" healthcare software and subsequently interpreted. Results: During the study period, a total of 1295 patients were hospitalized. Cataract was the most common reason for hospitalization (n=355, 27.4%), followed by ocular trauma (n=303, 23.4%) and rhegmatogenous retinal detachment (n=287, 22.2%). The majority of patients with eye trauma (n=125, 41.2%, p<0.001) were between 19 and 44 years old. Male predominance was found in ocular trauma (n=261, 86.1%, p<0.001), and also in patients hospitalized for rhegmatogenous retinal detachment surgery (n=166, 57.8%, p<0.001) and surgery due to complications of proliferative diabetic retinopathy (n=41, 71.9%, p<0.001). Patients aged between 45 and 64 years were at the highest risk (n=136, 47.4%, p<0.001) and vitrectomy was performed more often as a treatment of rhegmatogenous retinal detachment (n=193, 67.2%, p<0.001). Rhegmatogenous retinal detachment most commonly occurred in autumn (n=103, 35.9%, p<0.001). Conclusion Further studies focusing more on some of the pathologies included in this study may be beneficial for a better understanding of epidemiology, preventive measures, and optimal treatment methods.

Introduction/Aim While echocardiography plays an important role in the follow-up of patients with precapillary pulmonary hypertension (PH), several studies have identified World Health Oganization's functional class (WHO FC), 6-minute walk distance (6MWD) and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) as the strongest prognostic markers. We investigated the relationship between echocardiographic indices, functional status and NT-proBNP in patients with precapillary PH. Material and Methods A total of 23 patients were included in this retrospective study. Data were collected from routine risk assessments, including WHO FC, 6MWD, NT-proBNP, standard, strain and three-dimensional echocardiography. The echocardiographic data were analysed in terms of the patients' functional status as determined by WHO FC, 6MWD and NT-proBNP values. Results Patients in WHO FC III or IV had a shorter 6MWD [180 (interquartile range 85-240 m)] than patients in WHO FC I or II [409 (interquartile range 364-494 m), p=0.02)], while the difference in NT-proBNP was not statistically significant [FC I or II: 1297 (interquartile range 283-3196) versus FC III or IV: 343 (interquartile range 274-598) pg/ml, p=0.146]. There were inverse correlations between 6MWD and left and right ventricular longitudinal strain and a direct correlation between 6MWD and pulmonary acceleration time (r=0.73; p=0.001). NT-proBNP measurements were directly correlated with right heart dimensions and right ventricular strain and inversely correlated with pulmonary acceleration time (r=-0.70; p=0.004). Conclusion Standard and advanced echocardiographic indices of right ventricular structure, function and hemodynamics correlate with functional status and natriuretic peptide levels in a heterogeneous cohort of patients with precapillary PH and may be useful ancillary parameters in clinical practice.
Cardiac cephalalgia
Authors: Cvetković Ana , Mijajlović Milija , Jokić Andrej
Published: June 2023

Cardiac cephalalgia has a small incidence, but unrecognized it can prolong the time to diagnose a life-threatening condition such as acute coronary event. According to its clinical presentation, it can refer to a migraine. Even in the absence of clinically and laboratory evident signs, the diagnosis of cardiac migraine should be kept in mind because sometimes it is the only symptom of a threatening coronary event. The choice of treatment depends on a correctly established diagnosis. A reckless inclusion of vasoconstrictors as a standard therapeutic modality of migraine in a patient with a cardiac cephalalgia could worsen ischemia and endanger the patient's life. By solving an acute coronary event conservatively, with percutaneous coronary interventions or coronary "bypass," cardiac cephalalgia is eliminated as well.
The Institute of Histology and Embryology in the most modern building of the Faculty of Medicine in Belgrade between two worlds wars
Authors: Puškaš Nela
Published: June 2023

The Institute of Histology and Embryology was founded in 1921, but it was moved into its own building a few years later, in 1927. The project of the building was done by the architect Svetozar Jovanović, and the pedimental sculpture in the gable of the building was done by the academic sculptor Živojin Lukić. The building housed two institutes: the Institute of Physiology and the Institute of Histology. Each of the institutes owned one wing, and they shared the central part of the building, which also contained an amphitheater. The building was equipped with the most modern technical devices and provided excellent conditions for scientific work and teaching. In addition, within the Institute of Histology there were the Photography Department, the Terminology Department, the central catalog of the books and journals of the Faculty of Medicine, and a museum was planned as well The largest part of the building was destroyed in the German bombing on April 6, 1941. After liberation, according to the project of the architect Milan Sekulić, the reconstruction of the central part and the construction of new wings of the building were carried out.

Published: June 2023

The increased volume of construction works, which includes the construction of new residential and business buildings, hotels, garages, shopping centers, and similar, is increasingly common in urban areas. Such works are increasingly coming into contact with different types of problems during construction, as one of these problems we single out the appearance of solid rock mass during excavation at the construction sites of future buildings foreseen in the construction project. During the construction of facilities or part of the building, which includes the underground premises of a building, it is necessary to excavate the material on site, however, due to its physical and mechanical characteristics, it is not always possible to excavate this material with conventional machinery. The composition of the material that is removed is sometimes in the form of solid rock, and thus its excavation is more complicated, so other methods must be used: controlled blasting, application of expansive mortars, etc. This paper presents some of the possibilities of removing solid rock material for the purpose of smooth construction of buildings.

Published: June 2023

The Vrška Čuka anthracite shows contents of 16% inorganic compound and 84% organic matter, out of which 82% is kerogen and <2% is bitumen. X-ray diffraction (XRD) indicates the presence of the graphitic structures. The electron spin resonance (ESR) shows a high concentration of polyaromatic paramagnetic structures (PPS; 4.5×10 19 spins g-1). The Fourier transform infrared spectroscopy (FTIR) reveal that the Vrška Čuka kerogen contains predominantly aromatic/polyaromatic structures. Analysis of the aromatic area shows both the absence of aromatic substituents and the presence of aromatic polycondensation (average 3-4 rings; ≥17 carbon atoms). The spectrum also shows considerably reduced absorptions corresponding to the presence of aliphatic groups. Most of the aliphatic carbon is present as CH 3 (probably in short alkyl chains-methyl/methylene attached to polyaromatic structures) as indicated by the CH 3 /CH 2 value 0.7 of the appropriate absorptions. It was suggested that polyaromatic structures were formed by poly-condensation of aromatics during kerogen maturation. Low atomic values of H/C and O/C (0.45 and 0.07) indicate a high degree of genesis (metagenesis). The result of these analyzes are in agreement with each other and show that the maturation of this kerogen led to the formation of polyaromatic structures from aromatic.

Background/Aim: Dementia has become a public health problem due to its association with biological risk factors; obesity, diabetes, hypertension and hypercholesterolaemia. Most of these risk factors, appear to be associated with dementia as well as with risk of coronary artery diseases (CADs) and stroke. This study aimed to find out the association of biological risk factors with cognitive impairment and dementia. Methods: Cross-sectional survey in a hospital was performed. After written informed consent and approval from hospital ethic committee, all subjects (n = 2002) above 25 years of age (1016 males and 986 females) were randomly selected and recruited from urban population of Moradabad, North India. Clinical data and risk factors were recorded with the help of case record form and validated questionnaires. Assessment of cognitive decline and dementia was made by Singh's memory function rating scale and biological risk factors by physical examination, sphygmomanometer and electrocardiography. The association of biological risk factors with dementia was calculated by multivariate logistic regression analysis after adjustment of age and sex. Results: Obesity, diabetes, hypertension, CAD and hypercholesterolemia were highly prevalent independent risk factors among patients with dementia. Multivariate logistic regression analysis showed that regardless of age and body mass index, diabetes mellitus and CAD were highly significant (p < 0.001) risk factors of dementia. Hypertension and family history of dementia were weakly but significantly(p < 0.05) associated with dementia. Conclusion: It is possible that increased frequency of obesity, diabetes, hypertension and CAD may increase the risk of dementia in an ageing population. Prevention and control of these biological risk factors may cause decline in the risk of dementia.

Published: June 2023

The price of goods and services represents an important factor of attracting tourists and improving destination competitiveness. However, a question arises, whether lower prices in tourism contribute to a greater number of tourist arrivals and higher tourism receipts. The purpose of this paper is to analyse a relationship between price competitiveness and tourist arrivals and tourism receipts in European countries. By means of a cluster analysis, the paper examines the homogeneity of European countries in terms of tourism price competitiveness based on the Travel and Tourism Competitiveness Report for 2017. The results of the research showed that European countries are not homogeneous as far as tourism price competitiveness is concerned. Moreover, countries with a lower price competitiveness level attract a greater number of tourists and yield greater tourism receipts in comparison to the countries with a greater price competitiveness level.

scanning), in order to predict and localize lameness and other problems in horses. Although case reports have been

published, there are no previous clinical studies on the correlation of positive AP scans (sensitivity of 1 or more acupoints)

and lameness. The authors hypothesized that a positive AP scan would correlate with a positive conventional lameness

examination. One hundred and two client-owned horses were presented for routine acupuncture, reduced performance or

lameness. Each horse first underwent a <2-minute screening scan of acupuncture points and was classified as positive or

negative for acupoint sensitivity. Then each horse was evaluated for lameness and categorized as lame or sound. In the

sound group, 40/51 (78.4%) horses had a negative AP scan and 11/51 (21.6%) had a positive AP scan. In the lame group,

9/51 (17.6%) horses had a negative AP scan and 42/51 (82.4%) had a positive AP scan (p<0.001). Acupuncture scanning

had a sensitivity of 82.4% to detect lameness and a specificity of 78.4%, with an accuracy of 80.4%. Significant but

modest correlations existed between the side of the horse that was positive on the AP scan and the side of lameness. The

conclusion of the study was that an AP scan could be a useful, quick screening tool during the physical examination to

identify horses that should undergo a full lameness examination and other diagnostic testing.

Tendencias actuales de producción y consumo de drogas ilícitas en México
Authors: Díaz Menció Sofía
Published: June 2023

En el marco de la creciente amenaza de las drogas sintéticas, adicional a las necesarias recomendaciones para fortalecer las instituciones de seguridad y justicia, el Gobierno de México debe impulsar tres acciones complementarias entre sí. Primera, incrementar la oferta de servicios de tratamiento y estrategias de reducción de daños en la frontera norte, donde se presenta el mayor consumo de opioides y, en consecuencia, de fentanilo en México. El mercado estadounidense de opioides sintéticos es una alarmante advertencia de lo que podría suceder en el país respecto a sobredosis letales. Al mismo tiempo, se debe seguir impulsando el acceso a medicamentos controlados para el dolor. Lo anterior, adelantando la implementación de buenas prácticas para prevenir un aumento en las adicciones a estos fármacos y su desvío al mercado ilícito. Segunda, se debe aprovechar el interés de las organizaciones criminales en las drogas sintéticas —en detrimento de las drogas tradicionales— para establecer programas ambiciosos de desarrollo alternativo con las comunidades cultivadoras que propicien la erradicación voluntaria de plantíos de amapola y su sustitución por productos agrícolas legales y rentables. Esto se ha implementado exitosamente en países como Colombia, Bolivia, Laos y Tailandia, y reduciría dramáticamente la producción y tráfico de heroína en territorio mexicano. Finalmente, es importante reforzar las fuentes de información para la toma de decisiones. Es muy difícil hacer frente a un mercado tan volátil como el de las drogas ilegales sin contar con datos actualizados y confiables sobre su dimensión y características. En este sentido, es urgente retomar la Encuesta Nacional de Consumo de Drogas, Alcohol y Tabaco (ENCODAT), cuyo último levantamiento fue en 2016–2017, así como fortalecer al Observatorio Mexicano de Salud Mental y Consumo de Drogas de la Secretaría de Salud. Similarmente, en el ámbito de la oferta, una mejor integración de las bases de datos de incautaciones de drogas ilegales y la importación de químicos precursores y esenciales permitiría identificar alertas en las cantidades y destinos de estos productos.

GEOLOGICAL AND STRUCTURAL MODELS OF FORMATION AND ACCUMULATION OF GAS IN MAN-MADE RESERVOIRS OF COAL ROCK MASSIVES
Authors: Vergelska N.V. , Skopychenko I.M. , Kroshko Yu.V.
Published: June 2023

The formation of technogenic reservoirs of coal-rock massifs is determined by the depth of development, lithological features of the host rocks and the gas content of the coal-rock massif. The formation and redistribution of gas-saturated zones and migration routes in coal-rock massifs continues even now, which is associated with modern fluid migration. Gas, filling the mine workings of closed mines, creates a threat to communications, structures as a result of explosions and has a negative impact on human health.

 It has been established that the regular distribution of gaseous hydrocarbons is determined by discontinuities and confirms not only the diffusion gas saturation of the massif, but also the tempo, that is, the gas saturation of the massif through discontinuities during tectonic (tectonic-magmatic) activations. At the same time, it should be noted that geological discontinuities were not the “transport arteries” of gaseous hydrocarbons not throughout the entire space. For most of its strike, coal and rocks in the zones of discontinuities are folded, and there is almost no gas transmission. The worked-out space of active mines is a new technogenic reservoir suitable for the accumulation of gaseous hydrocarbons, the thickness of which exceeds the thickness of the coal seam. The active processes of gas migration in the exhaust space are indicated by the study of the residual gas component, in the mixture of which helium, hydrogen and quantitative changes in hydrocarbon gases (C2 - C6) were found.

Authors:   Mentor Graphics, Mechanical Analysis Division, Gurov Leonid , Ivanov Andrey
Published: June 2023

Numerical simulation results of specific supersonic and hypersonic flows interactions leading to complex shocks structures are presented in the paper. These interactions can produce abnormal thermal loads that should be taken into account for Thermal Protection System design for hypersonic vehicles. Calculations were made with the aid of CAD-Embedded CFD software FloEFD. To validate the CFD code in this field a study of shock/shock interaction near 2D cylinder has been carried out. Good agreement with experimental data in terms of shock structure, surface pressure and surface heat flux distributions was obtained. To demonstrate how these shocks interactions effects can affect in case of a real 3D complex hypersonic vehicle a 3D study of interaction between the Space Shuttle Orbiter bow shock and External Tank bow shock under certain flow regime has been carried out. Comparison with the data obtained in the simulation of the ‘single Orbiter’ flow showed a small-scale zone on Orbiter nose with considerably increased peak pressure and heat flux values due shock/shock interaction.

This study aimed to develop a workstation to investigate robotic sanding processes of wooden parts. The applied methodology includes the conceptual design of the station, incorporating sensors for online measurement of process variables. The station is controlled by a computer that enables interaction with the robot, controlling the abrasive tool rotating speed, and acquiring and visualizing the process signals. The implemented workstation was used to investigate the influence of the sanding parameters on the process variables. The results established that the grain size and the rotational speed of the sandpaper produce statistically significant variations in the surface finishing. Finally, equations are proposed for relating the surface roughness with the sanding torque and acoustic emission measured during the operation.

Total Productive Maintenance (TPM) is one of the main maintenance management strategies based on the principles of Lean Manufacturing (LM). The emergence of the Industry 4.0 (I4.0) paradigm has promoted the massive digitization of several functional areas, with predictive maintenance standing out as an ideal field for the application of IIoT (Industrial Internet of Things) sensorization and data analytics. However, TPM encompasses many more techniques and the scientific literature shows that the integration of I4.0 with TPM needs further development to understand how technologies can support continuous improvement. This paper explores the relationship between TPM and I4.0 tools. It proposes a roadmap for its implementation in SMEs to achieve a Cyber-Physical TPM 4.0 system. The proposal is being validated by means of a practical case study in an industrial SME, with no previous experience in TPM, and which is pursuing the digital transformation of its processes.

Planetary gear train is widely used in large heavy-duty machineries such as helicopters and ships due to its large transmission ratio, strong bearing capacity, and small size. In this paper, and the load sharing ratio (LSR) and overall transmission error (TE) of a two-stage double-helical planetary gear train are studied. Firstly, the static balance equations of the double-helical planetary gear train are established. Then, the LSR under different mesh phasing and the overall TE are obtained by solving the equations. Finally, different errors such as pinhole position and eccentricity error are taken into consideration and the influence of errors on load sharing ratio and transmission error are analyzed. The results show that the excitation frequency of transmission error is related to the number of planet gears and mesh phasing and the LSR is related to the mesh phasing, especially to the sequentially phased transmission. It is also concluded that the excitation frequency of the output element of the two stages can be seen as the superposition of the mesh frequencies of each stage and that the studied errors have a significant impact on the LSR and the TE.

At present, China has entered the peak stage of large-scale maintenance, but repair materials for asphalt pavement potholes are subjected to problems, such as low construction efficiency and poor durability. Polyurethane modified epoxy acrylic resin was selected in this study to repair pavement potholes rapidly and improve durability further. Meanwhile, the cementing material and aggregate were formed into a mixture for rapid repair. A four-factor and four-level orthogonal experiment was designed, and the optimal mass ratio of each component of the cementing material (EPMY) was determined according to three indexes: tensile strength, elongation at break, and viscosity. The basic properties of the material were evaluated using viscosity, glass transition temperature, thermal stability, and elastic recovery rate tests. Finally, the mechanical properties of EPMY immersed in water, salt, acid, and oil solutions were tested under different environmental stimuli. Results showed that the optimal mass ratio of epoxy resin binder is 100% epoxy acrylic resin:15% diluent:30% toughening agent:60% curing agent:6% accelerant, with a tensile strength of 21.48 MPa and an elongation at break of 48.3% at ?10 °C. Elastic recovery rate is 51.3% at room temperature, glass transition temperature is ?13.6 °C, and mass residual rate of EPMY is 10.06% when the temperature rises to 500 °C. The mechanical properties of EPMY are maximally affected by the acidic solution; and the elongation at break, bending strength, and bending deformation are reduced by 11.63%, 7.52%, and 9.58%, respectively. Moreover, and the elongation at break of EPMY can be maintained above 89%. The cementing material can be used for the rapid repair of pavement potholes, thereby increasing the convenience of maintenance work and improving the maintenance level.

Foreign experience in legal regulation of cryptocurrency taxation
Authors: Andrianova Natalia Gennadievna
Published: June 2023

The active development and distribution of cryptocurrencies around the world raises a natural question about the need to determine the procedure for legal regulation of taxation of transactions with cryptocurrencies. In this article, on the basis of the comparative legal method, the author examines the experience of legal regulation of cryptocurrencies and the procedure for their taxation in foreign countries. As part of the study, the experience of the United States of America, Singapore, New Zealand, Iran in terms of the legal regulation of cryptocurrencies and the procedure for their taxation is analyzed. It has been established that each of the above-mentioned states adheres to its own special approach in terms of regulation and taxation of cryptocurrencies. As a result of the study, three main models of legal regulation and taxation of cryptocurrencies in foreign jurisdictions were identified: the first approach is based on the recognition of cryptocurrencies as a type of convertible virtual currency that can be used as a means of payment. At the same time, in this approach, for tax purposes, cryptocurrencies are considered as property; under the second approach, cryptocurrencies are not recognized as legal tender. In the second approach, cryptocurrencies are treated as property for tax purposes; the third approach is based on a complete ban on the use of cryptocurrencies in the state, taxation of transactions with cryptocurrencies is not established.
A meaningful analysis of the updated Federal State Educational Standards and the problem of implementing their requirements in the work of a teacher
Authors: Mansurova Svetlana Efimovna
Published: June 2023

The subject of the study is the updated Federal State Educational Standards (FGOS) of all levels of general education. The object of the study is the formation of a unified educational space in the Russian Federation, one of the leading instruments of which is the Federal State Educational Standard. The study presents a detailed analysis of the requirements of the Federal State Educational Standard for the results of the development of basic educational programs. Special attention is paid to the professional competencies of the teacher, which determine the possibility of forming results within the framework of subject-based learning. The study was carried out on the basis of a meaningful analysis of updated FGOS and other regulatory documents, statistical analysis of FGOS of different generations, monitoring studies of professional competencies of teachers. Based on the conducted research, a number of conclusions were made. It is revealed that the leading update of the Federal State Educational Standard is the concretized and systematized requirements for personal, meta-subject and subject results of mastering the basic educational programs, which are holistically presented in relation to training and upbringing and formulated in an activity form. It is shown that the updated FGOS answer the systemic questions "what to teach?", "how to teach?", "why to teach?", i.e. they have an applied nature. The requirements of the Federal State Educational Standard set the framework of requirements for the professional competencies of a teacher – subject, methodological, personal. The study revealed the deficits of professional competencies, the leading of which is the willingness and ability to carry out professional activities on the basis of a system–activity approach, which acts as a system-forming condition for the implementation of requirements for learning outcomes. The scope of application of the research results is to determine the directions of professional development of teachers in the context of changes in the regulatory framework.
Transformation of the image of Baba Yaga performed by George Millar in the films of Alexander Rowe
Authors: Shumov Maksim Vladimirovich
Published: June 2023

The image of Baba Yaga in the folk culture of the ancient Slavs is considered as an object of research in this work. As an important part of folk culture, Russian folk tales take upon themselves the responsibility to broadcast traditional moral qualities and form the basis of a person's evaluative and emotional attitude to the world. The subject of the study is the transformation and interpretation of the image of Baba Yaga performed by the People's Artist of the RSFSR Georgy Millar in the film tales directed by Alexander Rowe. The authors set a goal to identify specific features in the interpretations of the image of Baba Yaga by George Millar and to identify the typology of these images. The methodological basis of the article is content analysis, comparative, statistical, historical and cultural analysis of the films narrator Alexander Rowe. The authors, when considering the problem, achieve the following results: Georgy Millar starred in 16 Alexander Rowe's fairy tales, while performing 27 roles; he played Baba Yaga in 4 fairy tales; only the first is the canonical image, the other three images are the personal merit of Georgy Millar. In the process of developing the problem, the authors identify comparative criteria of Baba Yaga images: external features, behavioral characteristics, character traits. The novelty of the research consists in the unconventionality of the indicated approach, as well as in a comprehensive analysis of the palette of creative possibilities of actor Georgy Millar. As a result of the study, the authors come to the following conclusions: 1) the centuries-old image of Baba Yaga is very complex and often contradictory, so it can be transformed and interpreted; 2) Georgy Millar created 4 different images of the same character - Baba Yaga "Witch", Baba Yaga "Old Housewife", Baba Yaga "Mother" and Baba Yaga "The lady."
