Investigations of Surface-Treated Wood by a Micro-Indentation Approach: A Short Review and a Case Study
Authors: Petric M. , Levanic J. , Paul D.
Published: December 2023

Over the past 50 years, instrumented indentation, in which an indenter tip probes the specimen surface with a regulated force and displacement to characterize its mechanical properties, has evolved. With the development of atomic force microscopy, instrumented nanoindentation has been extensively applied, and instrumented indentation in the micro range (micro-indentation) has been somewhat overshadowed by nanoindentation. However, micro-indentation remains an extremely useful technique that has the potential to investigate various properties of surface treated wood. In the first, overview-type part of the paper, instrumented micro-indentation is described and some examples of its possible applications in the field of wood science and technology are presented. To illustrate the importance of this experimental technique, some results of micro-indentation experiments carried out in our wood surface treatment laboratory are shown in the second part of the paper. The objects of the tests were untreated Scots pine wood and Scots pine wood with surface deposits of SiO2 or ZnO. The differences between the mechanical properties of early and latewood could be clearly distinguished by the micro indentation technique. On the other hand, the influence of ZnO and SiO2 particles on mechanical properties as a function of indentation depth could not be detected by this technique.
An Experimental Method to Evaluate the Contribution of Wood Substrate and Coating Film to the Light Induced Colour Changes of Wood Surfaces
Authors: Torcatoru M. Jr. , Timar M.C.
Published: December 2023

The paper presents an original laboratory method developed to determine and compare the light-induced colour changes of uncoated and coated wood surfaces, while also allowing the highlighting and evaluation of the individual contributions of the substrate and coating film to the global effect. Two types of wood test samples: V1 (uncoated) and V2 (coated) and coating films on 1mm thick clear glass slides were employed. The behaviour of the wood substrate under the coating film was simulated on uncoated substrate covered with a coated glass slide. European maple (Acer pseudoplatanus L.) and two types of transparent water-based varnishes with 2k formulations were used. The samples were exposed for up to 72 hours to artificial UV-VIS light in accelerated tests simulating natural light passing through window glass. Colour changes were measured in the CIELab system, as well as the chemical changes of the wood substrate and the coating films by FTIR analysis. Exposure of uncoated maple wood resulted in a total colour difference (E) of 10.83 units and this was only slightly reduced by coating (9.29-9.81 units). Exposure through the glass slide reduced the colour changes of the uncoated and coated wood surfaces by 37-43%. Colour changes of 5.79-6.85 units were measured on the wood substrate exposed under coated glass slides, whilst the colour changes of the coating films on glass slides were only 0.64-1.0 units, which indicates a maximum contribution of the wood substrate to the light-induced colour changes of the coated surfaces. FTIR investigation confirmed this finding.

Towards an Ontology of Viewpoints
Authors: Gillis-Webber Frances
Published: December 2023

In a multilingual domain ontology developed using the labels approach, where each ontological entity is labelled with a language-tagged string, two scenarios result: (1) the ontology is ‘language-independent’, where there is an equal number of labels per natural language, or (2) the ontology is a ‘primary-language’ ontology, where one natural language takes precedence over the other languages used. In a multilingual ontology, it is assumed there is full equivalence between the different languages, however, each natural language, as an embodiment of a culture, differs in how it interprets and organises the world. The result is that although the viewpoint expressed by the multilingual domain ontology is thought to be universal, one natural language is very often privileged, typically English. Using the culture-bound concepts of ‘dowry’ and ‘bride price’, we demonstrate the differences in perspective when considered for different languages and sub-domains. We propose an ontology, Model of Multiple Viewpoints (MULTI), where both language and culture are considered together, and language is classified as a social norm of a community. MULTI is formalised in OWL and aligned to DOLCE+DnS Ultralite, a foundational ontology suitable for modelling contexts. The evaluation of MULTI is done against the identified use cases. The expected result is that an ontology can be annotated with its viewpoint, thus making the viewpoint of the ontology explicit.

Data analytics is the best approach for extracting hidden patterns and trends from time series data. One strong limitation that restrains the use of the method is the difficulty in selecting the appropriate data when a large variety of records come from several providers. Domain ontologies can organize and offer a uniform view for data analysis without plastering the data in a rigid format. This work describes an innovative visualization platform for data analysis of petroleum production time series that allows the user to explore the semantics of the oil well data with the support of a well-founded domain ontology. The O3PO ontology represents a production plant’s installation assets, describing the equipment’s relevant properties, such as position, relationship with other assets, and sensor measurements. The visualization platform takes advantage of the ontology to assist the user in locating the installation component, equipment, and collected measurements, bringing the time series data to the analytic tool for analysis by various groups. The ontology provides a taxonomy for navigating between classes and subsequently selecting instances, components, and properties. We describe the use of the visualization tool in real-case data from an offshore oilfield in Brazilian Pre-salt. This work contributes to the conception of the next generation of digital twins for the oil and gas industry.

Determining the estimated cost of project works using aggregated indicators of labor intensity.
Authors: Gritsenko О. , Zapiechna Y. , Shevchuk K. , Gavrilyuk V.
Published: December 2023

The article is devoted to the determination of the estimated cost of project works using aggregated indicators of labor intensity. The instruction on determining the estimated cost of design works of construction objects provides for the application of percentage indicators of the cost of design works to the calculation base. The cost of the calculation base is determined with the help of similar objects, or by aggregated indicators of the cost of construction per unit of measurement. The use of analog objects has a number of disadvantages, namely: limited experience and qualifications of designers, an indefinite number of comparative objects that are available in the archive of the project enterprise, the total cost of the analog object includes the cost of material resources that affect on the estimated cost of the analogue object, and accordingly on the cost of the estimated project documentation.

To get rid of the presence of the specified shortcomings, it is necessary to change the basis of justification for determining the cost of project works. It was found that the basis can only be regulatory labor intensity, as it is stable and uniform for all regions of Ukraine.

The authors propose to change the basis of the justification for determining the cost by arriving at the determination of the labor intensity of the analogue object using the following methodology. The methodology shows the extent to which specific values of technical and economic indicators change for homogeneous groups of housing reconstruction objects and regression equations of specific values of labor intensity for certain types of works of a similar object.

The methodology was developed on the basis of normative labor intensity values of more than 30 objects of housing reconstruction. It was determined that the normative labor intensity depends on the technical and economic indicators of the objects under investigation, namely: perimeter, height, superstructure volume and base area. As a result of the study, the limits of technical and economic indicators corresponding to 3 regression models of specific values of normative labor intensity were obtained.

To verify the specified methodology, an example of determining the specific labor costs of a similar object depending on the specific values of the technical and economic indicators of the new object based on the regression equations of homogeneous groups is given. According to the equations of homogeneous groups and the corresponding technical and economic indicators, a search is made for the correspondence of the technical and economic indicators of the object under study.

The specified method allows you to find a quantitative estimate of the cost of project works by individual types.
Сorporate social responsibility of construction enterprises: status, development trends and implementation policy
Authors: Seredyuk K.V.
Published: December 2023

Striving for sustainable development in the conditions of globalization processes and in the period of transformation of the country's economy, assessing the current state of corporate social responsibility (SCR) of construction enterprises, the need to study the state and trends of policy development and its implementation practice is determined.

The social responsibility of companies, regarding the sustainable development of the whole society, is an important approach for construction enterprises in responding to new social and environmental problems.

An important aspect of modern civilized business, including construction, is the basis of the csr concept, the implementation of which in the field of enterprise management has an extremely important direction not only for creating a positive image of the company, but also for increasing its competitiveness both on a global scale and at regional levels management. Therefore, the expediency of combining csr activities with the specifics of the company, which must invest in potentially useful areas of knowledge and innovative solutions, becomes especially important.

The efficiency of construction enterprises that implement csr in their activities has not yet reached the optimal level, the influence of institutional factors on csr efficiency is complex and non-linear, and the improvement of csr efficiency in the construction industry depends on both the optimization of the institutional environment and the improvement of the potential of csr efficiency management.

The necessary changes in the existing practice of csr management should have a certain systematicity, which should include the integration of csr principles, methods and tools in the economic activity of enterprises in order to ensure their competitiveness, achieve high productivity and profitability.

The research was carried out with the help of a review of scientific literature, modern studies of expert organizations, public organizations and policy research on csr issues of construction enterprises. The results of the study showed that there have been major positive changes in the evolution of the csr concept in ukraine over the past few years, but there are still some unresolved problems with which enterprises are forced to work.
Theoretical approaches to the analysis of the life cycle costs of the project for the construction and reconstruction of sports and recreational facilities in Australia
Authors: Tsyfra Т. , Vilnytska N. , Shevchuk К.І.
Published: December 2023

The article highlights the theoretical approaches to cost analysis of the life cycle of a construction project. Most sport and recreation facilities in Australia are built or renovated with funding from the Department of Sport and Recreation. An important part of the financing process is making sure that the community can bear the real costs of operating and maintaining the facility in the future. The Life Cycle Cost Guidelines provide facility owners, architects and engineers with the tools they need to develop life cycle cost reports to be used by the department when it reviews publicly owned or community funded facilities. The Department of Sport and Recreation is committed to achieving the most desired project outcomes that reduce capital expenditure in the sport and recreation industry Developing a life cycle costing approach when considering project parameters will provide a strong and informed basis on which to make the most effective financial, economic and operational decisions decision. Life cycle costing is a key asset management tool that considers the entire life cycle of planning, acquisition, operation, maintenance and disposal of an asset. The final decision may include a number of additional factors outside of the LCCA process, such as local policies, availability of funding, rating of repair deficiencies , the ability of the industry to perform the required construction and the experience of the agency, and the accuracy of the design. The generalization of theoretical approaches shows the possibility of applying methods of financing the construction/reconstruction of objects, taking into account the analysis of the costs of the life cycle of the project of new construction and reconstruction of sports and recreational facilities not only in Australia, but also their adaptation to Ukrainian realities in the conditions of post–war reconstruction.
Methodology for studying the efficiency of new structural and technological solutions for the restoration of building structures' suitability for use
Authors: Tonkacheev G. , Molodid O. S. , Molodid O. O.
Published: December 2023

The article presents the developed, scientifically based methodology for introducing the construction practice of new structural and technological solutions for restoring building structures in reconstruction or capital repair conditions. This technique is based on the practical experience of surveying building structures, establishing the type and extent of damage, and the need for their reinforcement. The authors found that more than 70% of repair and restoration work on structures must be performed using classic technologies, 20% of cases require using existing modern methods, and almost 10% - develop new forms of repair and restoration work.

In the publication, the authors present methods of researching the effectiveness of new structural and technological solutions for restoring the operational suitability of building structures. Experimental studies of new structural and technical solutions should be performed in several stages: laboratory and experimental model studies, by checking the results in real conditions at construction sites.

A structural diagram of the research methodology of the latest and new structural and technological solutions for restoring the operational suitability of building structures has been developed, which offers a set of steps that allow, based on their results, to obtain new structural and technological solutions that can be applied in practice and have high quality. Each research stage of such solutions is characterized in detail, and a set of necessary elements is defined, allowing each stage to be implemented.

In the case of the study of fundamentally new and complex structural and technological solutions for repair and restoration works of building structures, full-scale experimental studies are performed. It is assumed that such studies are carried out directly on single structures that need to be restored to operational suitability and subsequently observed during a certain period of operation.

The developed methodology made it possible to carry out several research works. As a result, new constructive and technological solutions for restoring building structures were introduced into construction practice.
Research and development of approaches for the analysis of the current pricing system of project work
Authors: Shumak L.
Published: December 2023

At the current stage of the transition period associated with military actions in the economy of Ukraine, the issue of pricing for design and scientific-project work in the construction industry is the most acute and the most relevant. The perception of price is increasingly associated with the designations fixed by this concept, such as "state", "market", "enterprise", "contract". The meaning of the price, however, is related to the price-forming factors that affect its value. In the conditions of market relations, the labor, material and financial resources of the project enterprise are part of the aggregate resources of society and are included in the general reproductive process by the project enterprise itself as a business entity. The regulation of reproduction occurs in combination with other economic and value laws acting through price mechanisms and pricing. Pricing policy and price management play an important role in the life of project enterprises - one of the main points in the strategic development of project enterprises. In order to form a high-quality price policy, project enterprises need to collect information about the market, conduct research, prepare and propose new projects, and optimize sales of project products. On the basis of the analysis of the collected information about the project market, the project enterprises form a price policy.

The article analyzes the available literature on design, construction, operation, monitoring, in particular, on determining the cost of design and scientific project works. The article contains the results of a literature review devoted to issues of pricing in design. Currently, there are no Designer's Guides available for costing design and engineering work, requiring practicing engineers and public universities to rely on experience and private service.

The article proposes scientific developments in the direction of improving the pricing of project works, which require, first of all, the study of clear trends and hidden regularities of the influence of a number of factors. An approach to determining the cost of design works is recommended, primarily taking into account the physical parameters of the design object and the economic factors of its construction. It is proposed to study the interrelationships between these factors: – using statistical data analysis methods; - means of artificial intelligence. In the course of the study, an in-depth analysis of the cost of design works was carried out for objects under construction in the city of Kyiv and the Kyiv region. The analysis of the cost of design works was carried out from individual elements of the structure.

The main part of the scientific research of the article on the determination of the cost of project works is devoted to the study of the problem of pricing and the development of approaches for the analysis of the current system of pricing of project works in Ukraine.

Comparative characteristics of accounting of fixed assets according to national and international standards
Authors: Ivanova T.N.
Published: December 2023

The article examines the existing accounting approaches to determining the essence, assessment, order of reflection in the accounting records of companies and disclosure in financial statements of information on fixed assets as a component of non-current (long-term) assets according to national and international accounting standards (international financial reporting standards).

The purpose of the study is to compare the existing requirements of the national and international practice of the accounting policy of fixed assets of the enterprise: definition of fixed assets, the structure of the formation of the initial cost, maintenance costs, methods of calculating depreciation and the order of disposal, identifying common features and differences in the accounting system in order to achieve harmonization of accounting in the world spacious

A comparison of the requirements of domestic legislative norms with international standards regarding the recognition and determination of fixed assets, the procedure for forming the initial value of objects, revaluation methods, the procedure for writing off fixed assets from the company's balance sheet, methods for calculating the depreciation of fixed assets and displaying information about fixed assets in the company's financial statements was carried out . The dependence of the separation of low-value non-current material assets from the composition of fixed assets on the established criterion of "materiality" and their write-off for enterprise expenses is established. The absence of the concept of "non-production fixed assets" in the international standards, which is common in national legislation, of the division of fixed assets into classes for accounting purposes was revealed. The division of the object of fixed assets into components for the purpose of calculating depreciation is considered. Differences in methods of calculating depreciation according to national and international accounting standards, revaluation methods and features of determining fair value according to international practice are analyzed.

Ways of harmonizing national and international standards in terms of fixed assets, which require clarification and detailing in order to improve the efficiency of operations and the financial condition of the enterprise, are proposed. The results of the conducted research have theoretical and practical value, because in the conditions of youth mobility, workload of practicing accountants and other specialists, there is a need for a wider coverage of practical aspects of accounting according to international standards and can be used in the accounting process of enterprises making the transition to international accounting practice.

Authors: Shpakova Н. , Shpakov A.
Published: December 2023

The article examines a wide range of strategies and approaches to rebuilding Ukraine after the war. Historical examples of post-war recovery programs of countries in the 20th century are highlighted. Special attention is paid to the recovery of European countries in the context of using their experience, in particular the possibility of applying the "Marshall Plan" for modern Ukraine. The main advantages and disadvantages of recovery plans, conditions of their application, effectiveness in the economic and time dimension are considered. The article analyzes in detail the recovery plan of Ukraine, proposed by the Committee on Economic Development of the Verkhovna Rada. Taking into account the changes that took place at the front, in the structure of political elites and economic processes in the world and in Ukraine during the year after the publication of the plan, negative trends are singled out that distort the current and final results. The challenges facing Ukraine are examined in detail, including the extent of damage, geopolitical location, and the need for innovative technological development. The authors propose a comprehensive approach to recovery that includes reforming domestic policies, institutional structures, and attracting international support. Attention is also focused on Ukraine's integration into European economic structures, considering it as a key element for stable recovery. There are also warnings about the difficulties that Ukraine may face in the process of implementing the recovery plan, including economic and political obstacles. At the initial stage, the sequence and priority of the main measures should be established: demining huge areas of land, clearing debris, building shelters, dormitories and schools, medical facilities for providing basic medical care. These are the conditions for a quick start of reconstruction. The priority areas of development are singled out - "specialization of the country": the agricultural sector and the military-industrial complex. The article is a contribution to the discussion about the restoration of the country, because it focuses on modern challenges and potential ways of development, adaptability of the system to external and internal factors of influence, key moments of various cases of the plan for the revival of Ukraine in the post-war period.
Optimal design of the forced oscillation frequencies of the minimum surface shell on a circular contour consisting of two inclined ellipses under thermal and power loading
Authors: Ivanchenko G.M. , Kosheviy O.O. , Zhupanenko I.P.
Published: December 2023

The problem of choosing the optimal design solution is a multi-purpose complex task, the solution of which requires taking into account a wide range of requirements for different stages of implementation. There are several levels of solving optimal design problems. The first level deals with general design models, including the main structural elements, taking into account the physical and geometric features of their behavior. This level can be called the "global" level of optimization. Due to the fact that the automated calculation of structures is impossible without the use of finite element models, and at the next "detailed" level, the parameters that make up this model (coordinates of nodes, physical and geometric properties of individual elements, etc.)

The choice of a finite element model for optimal design is directly related to the complexity (the possibility of computer implementation) of the optimal design problem. To reduce the computational procedures associated with solving the problem of numerical analysis, an approach based on the approximation of system parameters (displacements, forces, frequencies, waveforms, etc.) can be used.

The problem of forced oscillations for shells of minimal surfaces is solved by the finite element method using the Lagrange's variational principle. The potential and kinetic deformation energies of the shell of a minimal surface are defined in matrix form as the sum of the potential and kinetic energies of each finite element.

The optimization algorithm for single-criterion parametric optimization is performed as follows: the objective function is the weight of the shell of the minimum surface on a circular contour consisting of two inclined ellipses, the design variables are the thickness of the shell, and the constraints are represented by the first forced vibration frequency. The results of changing the objective function are a decrease in the weight of the shell by 3050 kg of C240 steel, which is a percentage equivalent of 13.4% without loss of strength and stability of the shell of the minimum surface on a circular contour consisting of two inclined ellipses, which proves the effectiveness of the authors' methodology.

Authors: Sirko Z. , Tsapko O. , Torchilevsky D. , Tsapko Yu. , Bondarenko O. , Apanasenko V.
Published: December 2023

The paper covers the issues of fire protection of cellulose-containing materials, in particular wood. It is shown that despite a number of valuable properties that wood possesses, it is a rather flammable material by its composition. It is known from the literature that one of the most important steps in protecting wood from fire is fire protection treatment. It is carried out in two main ways: surface treatment (applying special compounds to the wood surface to form a fireproof layer) and deep impregnation of wood with flame retardants. For the fire protection of OSB samples, a water-based intumescent paint consisting of a system of flame retardants in combination with fillers, pigment, and functional additives was developed. The research was conducted using analytical and experimental methods, which consist of analyzing and studying the provisions of national standards that describe the method for determining the flammability group of substances and materials and the method for determining the fire protection efficiency of fire retardants. The experimental part of the study involved the manufacture of test samples, application of fire retardants to them, recording the temperature of gaseous combustion products, the maximum temperature increase, the time interval for reaching the maximum temperature, the weight of the samples, and the weight loss of the samples. The research methodology states that the wood samples were tested in accordance with DSTU 8829 at the OTM installation. It also provides means for measuring the flue gas temperature, test time, and determining the mass loss of samples before and after testing. The test results showed that the developed fire retardant based on intumescent paint provides a group of refractory materials in accordance with DSTU 8829, i.e., the wood protected by this method belongs to refractory materials, namely: the flue gas temperature does not exceed 260˚C, the mass loss of samples after testing is not more than 60%.
Analysis of methods of assessing the risk of investment projects in the aspect of recovery of the national economy
Authors: Sorokina L. , Hoikо A.
Published: December 2023

Qualitative and quantitative methods of risk assessment of enterprise investment projects and features of their use are considered. A brief overview of modern risk assessment methods is presented, their advantages and disadvantages are indicated. Disadvantages of existing methods include the need for large volumes of reliable source information over a long period of time (statistical method); difficulties regarding the laws of distribution of the studied parameters (factors) and resulting indicators (statistical method, simulation modeling); isolated consideration of a change in one factor without taking into account the influence of others (sensitivity analysis, stability testing method). Fuzzy logic methods are not devoid of subjectivity in assessing the degree of acceptance of a particular consequence caused by the appearance and intensity of prerequisite factors.

The value of the elasticity coefficient for the indicators of the investment project was studied and those that require increased attention during the implementation of the investment project in order to reduce the level of risk were determined. The need to use the method of sensitivity analysis of performance indicators in the process of implementation of the investment project to assess risk in order to reduce its level and minimize or avoid it is justified. losses, which allows you to determine the most risky initial factors of the project, which contribute to an increase in risk, and therefore negatively affect the final results of its implementation (NPV), and methods of fuzzy logic, which make it possible to combine qualitative and quantitative methods of assessing the risks of capital investments and contribute to the justification of expected loss of cash flows, despite doubts about the effects of various destabilizing factors of the mega, macro- and microeconomic environment. The author's methodical approach to assessing the loss of cash flows from capital investments in the conditions of hostilities in certain regions of Ukraine is proposed. The basis of the developed approach is the elements of the theory of fuzzy sets, in particular operations on fuzzy relations.
Tools for stakeholder interaction and adaptation of business processes in the modern business environment
Authors: Podoinitsyn S. , Stetsenko S.
Published: December 2023

In the modern world, interaction between stakeholders is an integral part of business. It allows for the achievement of common goals and ensures the sustainability of enterprise development. However, stakeholder interaction is not always easy and seamless. Sometimes it can face obstacles that arise from different interests and views on business development. It is important to note that interaction between stakeholders should be based on mutual trust and understanding. In this way, companies can ensure effective interaction and achieve common goals. To do this, it is necessary to take into account the interests of all stakeholders and ensure mutual benefit in the interaction.

One approach to achieving common goals is to consider stakeholder interaction as the adaptation of business processes in new realities. Digitalization of business processes can help companies be more efficient and competitive. For example, the use of cloud technologies allows for the storage and processing of large amounts of data, which facilitates decision-making processes and ensures a quick response to changes in the internal and external environment. Business process reengineering involves a complete review and transformation of business processes in order to achieve better results. This can be useful for companies facing complex stakeholder interaction problems. For example, reviewing the communication process with customers can help provide better service and meet customer needs.

The result of stakeholder interaction and changes to existing business processes may be the replacement of internally developed algorithms with entirely new steps or the modernization of stakeholder interaction processes. Adding important elements that allow for the management of other stakeholders' interests can provide expected but higher quality results. Therefore, stakeholder interaction is a key factor in business success.

This article reviews data on the incidence of ARVIs and novel coronavirus infection (COVID-19) in the Russian Federation and key antiviral therapies for ARVI and discusses recent published data on the use of various antivirals for COVID-19 treatment, with particular attention to potential biological drug targets. Data from several studies on the broad-spectrum antiviral drug riamilovir are addressed. Riamilovir was found to be highly effective with good tolerability and a favorable safety profile. The range of antiviral activity of riamilovir has significantly expanded over the past few years. In particular, this drug can be used for both the treatment and prevention of COVID-19. Riamilovir was approved by the Russian Ministry of Health not only for ARVI but also for COVID-19 infection and was included in the Clinical Protocol for the inpatient treatment of patients with COVID-19 admitted to Moscow public health system medical institutions. Moreover, riamilovir is also included in the Standard for the diagnosis and treatment of novel coronavirus infection in military personnel of the Armed Forces of the Russian Federation as an etiologic agent of choice for COVID-19 treatment. KEYWORDS: antiviral therapy, riamilovir, ARVI, influenza, SARS-CoV-2, COVID-19.

Published: December 2023

Infection with HPV genotypes is a cause of cervical and pharyngeal cancer, _etc_. The amount of circulating HPV DNA in the blood is useful for detecting advanced/recurrent cancer earlier than the rise in tumor markers. Compared to HPV infection-negative cancer, cancer immunotherapy is more effective for HPV infection-positive cancer.
Conceptosphere of cultural mediatisation
Authors: Levchenko Anton
Published: December 2023

The purpose of the article is to clarify the essence of the concept of "mediatisation of culture" in the modern context, to analyse the range of its conceptual sphere and its impact on the socio-cultural space of Ukraine. Research methodology. To achieve this goal, a number of research methods were used. Thus, to consider the interaction of cultures in the traditional space of communication and the space of social networks, the method of comparative analysis was used. To identify the mechanisms of formation of cultural boundaries, as well as their overcoming, the method of analysing open sources of information which are information resources on the Internet was applied. For qualitative and quantitative study of documents characterising the modern content of the concept of "mediatisation of culture", analytical synthesis was used. The method of theoretical generalisation allowed summarising the data obtained in the course of the study. The scientific novelty of the study is due to the need for new scientific views on the processes that shape and characterise the mediatisation of the cultural sphere of our time. An attempt to do this by defining a number of related concepts, united by the concept of conceptosphere, is qualitatively new. This study, which is comprehensive, takes into account the changes taking place in the cultural environment under the influence of the media. It takes into account their role in shaping the modern socio-cultural space of Ukraine, especially in the context of Russia's military aggression against Ukraine. Conclusions. The study examines the concept of "mediatisation of culture" in the modern context and its impact on the socio-cultural space of Ukraine. The work takes into account important changes in the cultural environment caused by the influence of the media, in particular their role in shaping the modern socio-cultural space of Ukraine.
