The object of this study is the algorithms and methods of affine transformations for the implementation of 2D transformations in graphic web editors. The research is aimed at applying the principles of these transformations and their impact on graphic objects, as well as at finding effective solutions for their implementation. An analysis of the main existing algorithms and methods for implementing 2D transformations, such as the Bresenham and Wu algorithms for visualizing straight and curved lines, algorithms for filling areas using affine transformation methods, was carried out. Therefore, the issue of improving and simplifying algorithms and methods of affine transformations for implementing 2D transformations in graphic web editors is relevant and important for modern web design and development.

The study specifically focuses on the creation of realistic 3D landscape models using open-source geospatial data such as OpenStreetMap and MapBox. The research analyzes the main methods of integrating geospatial data into the Unity environment, identifies the advantages and disadvantages of different approaches, and examines the role of operating systems in supporting this process. To achieve the objectives of the study, several key tasks were undertaken: the selection and preliminary processing of geospatial data from open sources, the adaptation of these data to Unity specifications through processes such as data conversion and the normalization of elevation values, and the integration of the data into Unity using specialized tools like Terrain Tools and Mapbox SDK. The study emphasizes the importance of optimizing these processes to ensure that Unity operates efficiently, even when handling large datasets. Particular attention was given to the methods used for data processing and visualization to achieve high performance. Techniques such as Level of Detail (LOD) management, texture compression, and material optimization were employed, enabling Unity to maintain stable operation even on systems with limited resources. The research further explores how different operating systems can impact the performance and integration capabilities of Unity when managing large datasets. It was found that while Unity’s flexibility and robust toolset allow for effective geospatial data integration, the efficiency of the overall modeling process is significantly influenced by the performance of the operating system and the optimization of Unity’s settings for specific use cases. These findings highlight the necessity of carefully selecting both the software environment and the data processing methods to maximize the platform’s capabilities. The results demonstrate that Unity is a powerful tool for 3D visualization, providing flexibility and support for various data formats, enabling the creation of realistic and detailed landscape models Beyond its application in traditional fields such as architecture, urban planning, and geodesy, the study reveals that the optimized models can also be effectively used in developing immersive virtual environments for educational and training purposes. Such environments can leverage real geospatial data to provide users with a more authentic experience, which is particularly valuable in fields like disaster management, military training, and environmental simulation. Additionally, the study suggests that the methods developed could be applied in the creation of interactive applications that require the integration of real-world geographic data. The practical significance of the findings extends to various industries, including not only architecture, urban planning, and geodesy, but also the entertainment industry, particularly in game development and virtual reality applications where high performance and realism are critical. The study’s conclusions provide a solid foundation for future research aimed at optimizing the processes of data integration and enhancing the functionality of Unity for handling a wider range of geospatial data sources. Future research could also explore the potential of integrating real-time data streams into Unity models, allowing for dynamic updates to landscapes based on current environmental conditions or other changing variables.

This work aims to explore ways to enhance the efficiency of structured text recognition through the integration of the YOLO model with OCR technology, as well as to develop an automated information system for detecting and subsequently recognizing text objects, which improves the overall efficiency of structured text processing. The developed system is a web application that enables users to upload invoices, store their data, and receive insights into expenses and client interactions. It includes a YOLOv10 neural network trained on a dataset of 500 invoice images, a REST API for user interaction, a user interface for invoice uploading, and a MySQL database to store information about users and their invoices. The authors propose a multithreaded architecture model that utilizes recurrent and two- and three-dimensional convolutional neural networks. The software, which implements algorithms for optical flow calculation and frequency analysis of characters, is developed in Python using Ultralytics, Pytesseract, Python Image Library, and Flask libraries. HTML, CSS, and JavaScript are used for the user interface, and MySQL is the chosen database model. The system’s main feature is the integration of the YOLO and OCR models to ensure accurate and fast recognition of text objects in images. The system architecture follows the MVC (Model-View-Controller) pattern, where the model handles data and logic, the controller acts as an intermediary between the view and model, and the view displays data to users. Each component has its respective roles and functions, making the system well-structured and easy to modify. Additional service layers are used for business logic and routing, and Flask’s Blueprint tool organizes the application into smaller components and URL structures. Overall, the system is well-structured, ensuring efficient data handling and a userfriendly interface for seamless interaction. The analysis of text recognition results demonstrated high OCR accuracy, particularly with structured text, though some limitations were observed, such as disruptions in the original text structure. These drawbacks can be mitigated by combining the YOLO network with OCR technology. Integrating YOLO with OCR enhances the system’s text recognition efficiency, enabling more precise detection of text objects and their subsequent recognition. Despite these achievements, there is room for further improvement, specifically in refining object detection and text recognition algorithms to achieve even greater accuracy and processing speed.</p> A.

The article is devoted to improving the performance of computing algorithms, which is one of the important areas of scientific research. SM4 to improve the performance of the algorithm. SM4 is a fairly common algorithm that is still in use today. At the moment, there are a large number of hardware and software implementations in which, using the features of the architecture or programming language, it is possible to ensure high performance of the algorithm. Symmetric cryptographic algorithms have a fairly high performance compared to asymmetric ones. Symmetric algorithms are used to encrypt messages or large files. Simple stages of the algorithms can be reduced to simple operations. This approach is described in the Ukrainian standard for symmetric stream encryption DSTU 8845:2019 (the Stream algorithm). Its peculiarity lies in the fact that the stages of the algorithm, nonlinear substitution performed using the cyclic shift operation, multiplication of the polynomial term by the field element, are simplified to a simple replacement from pre-calculated tables of constants. The article reveals that, as a result of this optimization, Strumok allows to form pseudorandom sequences with a speed of more than 10 Gbps. Today, the SM4 block encryption algorithm is widely used in the LibreSSL library, which is responsible for establishing a secure network connection according to the SSL/TLS protocol, and is part of the Libgcrypt cryptographic library, which is developed by GNU Projects. It was found that despite its widespread use, the algorithm itself does not have the optimization paths that Strumok has. The article optimizes the mathematical apparatus of SM4, which uses the peculiarity of the cyclic shift operation and reduces the calculation action to a direct replacement from the tables of constants, as was done in the national algorithm Strumok. The article proves that the optimization of the algorithm is a reduction of computational operations to direct replacement from the tables of constants. The article describes how the tables of constants are formed, as it was done in the national algorithm Strumok. The article determines that the software implementation of the basic and optimized algorithms showed that the execution time of the optimized SM4 decreased by about 2.69 times, which means a positive impact of optimization on the algorithm’s performance. The speedup was tested for different sizes of incoming messages.</p> G. L. Kozina, Yu. V. Savchenko, V. O. Voskoboinyk, D. I. Prokopovich-Tkachenko, V. V.

The method aims to ensure effective responses to threats associated with the development of quantum computing, which may compromise existing cryptographic protocols such as RSA and ECC. The critical role of artificial intelligence in analyzing, forecasting, and dynamically adapting defensive systems is highlighted. During attack modeling, simulations are conducted to evaluate the impact of quantum computing on cryptographic systems, specifically assessing the resilience of key protocols against attacks by Shor’s and Grover’s algorithms. At the adaptation stage, quantum-resistant cryptographic solutions such as lattice-based algorithms, code-based schemes, and hash functions are implemented, and their effectiveness is monitored. This is followed by a threat analysis that focuses on exploring the capabilities of quantum computing to break current cryptographic systems. The next step is a vulnerability assessment that identifies the cryptographic algorithms used, such as RSA and ECC, and analyzes their resistance to quantum attacks. This is followed by an analysis of critical points and communication protocols, which includes assessing the resistance of protocols such as TLS/SSL, IPsec, VPN to possible quantum attacks. The next stage is attack simulation, which involves modeling quantum attacks to assess the likelihood of their success. The final stage is the development of post-quantum security solutions, which includes the selection and implementation of new cryptographic algorithms that are resistant to quantum attacks and their integration into existing systems. All stages are interconnected and ensure the dynamic adaptation of the system to new challenges. It has been proven that the proposed approach enhances the resilience of information systems to new threats by integrating classical and post-quantum protocols. Particular attention is given to the synergy of various security components, enabling the creation of adaptive and self-organized systems.

Remote sensing provides information about objects at the surface of the Earth based on analysis of electromagnetic radiation reflected or emitted from these objects. Modern methods and technologies of remote sensing of the Earth make it possible to distinguish different objects at the surface of the Earth, to analyze these objects and changes, make predictive assessments. This technique is applied for numerous fields, such as: geology, ecology, geophysics, geography, hydrology, oceanography, meteorology. Remote-sensing application involves two distinct processes: data acquisition and data processing. One of the most difficult data processing procedures is the classification procedure. Classification is based on that fact, that different objects have a different spectral reflectance. Classification procedure is defined as the process of categorizing all pixels in an image to obtain land cover map. There are different classification approaches that have been developed and widely applied for solution of various tasks, such as maximum likelihood method, minimum distance method, parallelepiped classification, Support vector machines (SVM). It were analyzed main advantages and disadvantages of these methods. It also was noted, that many classification approaches can not process vague and conflicting information. It was proposed to apply the Dempster-Shafer evidence theory and Yager’s combination rule for classification of ambiguous and contradictory data from different spectral bands. The application of Dempster-Shafer evidence theory arises from the necessity to overcome some limitations of Probability Theory. It was also considered a formula of Yager’s combination rule in this work. It was noted, that Yager’s combination rule can quickly and easy process information. It was considered the numerical example, where Dempster-Shafer evidence theory and Yager’s combination rule were applied for classification in this paper. It was noted, that choice of classification method depends of specific task. Described methods for aerospace image processing can be applied in different actual ecological, agriculture and practical tasks.</p> S. I.

Gastronomic tourism is one of the types of excursion and educational tourism that was formed at the end of the 20th century. This is a relatively new but extremely interesting direction of the tourism business, which is actively developing, allowing travellers to learn about the cuisine of different countries and ethnic groups. The research uses the methods of structural-logical and semantic analysis (to clarify the terminology and conceptual apparatus of gastronomic tourism); system analysis (to assess the current state and prerequisites for the development of GT in Georgia), statistical method (to assess the place of GT in the tourist industry of Georgia), graphic method (for visual presentation of statistical data). The formation and development of gastronomic tourism in the world, its importance for the formation of the image of the territory are analysed. It is determined that gastronomic tourism is an integral part of all tours, and gastronomy has the potential to increase the attractiveness of the tourist product and tourist destination in general. It is proved that creating a favourable image of a country through the prism of national cuisine is a successful marketing ploy that helps attract tourists. It is intended, on the one hand, for tourists seeking knowledge and experience of new cultures, and, on the other hand, it provides additional value to the brands of tourist destinations. The influence of international (the World Food Travel Association and others) and national gastronomic tourism organisations on its development is characterised. The place of gastronomic tourism in the tourism industry of Georgia and the prospects for its development are analysed. It is proved that the culinary and wine sectors of Georgia play an important role. Thus, the contribution of the "Food and beverage service activities" sector in recent years has been approximately 20% in the GDP structure of the tourism industry. The analysis of the Georgian tourism sector has shown that gastronomic tourism in Georgia has significant potential to contribute to the development of new quality tourism products and experience. For its part, the National Tourism Administration of Georgia is doing its utmost to promote gastronomic tourism both nationally and internationally.</p> Z. V. Boyko, N. A. Horozhankina, M. V.

It has been established that the global hostel market reached USD 4.1 billion in 2022. The leader in the hostel market is the Asia–Pacific region, which is experiencing active recovery in international tourism following the COVID–19 pandemic. The European region ranks second, followed by the Americas. It has been determined that the largest share of hostel guests consists of individuals aged 25 to 34. The TOP–5 hostel networks in the world as of 2022 were: a&amp;o Hostels, Zostel, Meininger, St Christopher’s Inns, and Nomads World. The current state of hostelling in Ukraine is analyzed. It has been established that at the present stage, under the conditions of Russian aggression in Ukraine, official statistics do not reflect the actual number of hostel establishments. The review of the hostel base was conducted based on online booking websites. Hotelmix offers guests hostels in 20 cities of Ukraine, totaling 272 hostels. The largest number of hostels is located in Kyiv (39.3% of the total number of available hostels), followed by Lviv (20%) and Odesa in third place (7.4%). Booking.com offers guests 275 hostels in various regions of Ukraine. It was found that not all hostels are listed on official online booking platforms. A SWOT–analysis of hostel businesses was conducted. Positive changes in the hostel market require joint actions from government bodies and hostel operators. Combined efforts from both sides will ensure measures at the national level to improve hostel operations and advance the hostel industry to a new stage of development, while simultaneously preventing the influence of negative factors arising from the weaknesses in hostel operations (lack of service quality standards, the mass emergence of economy–class hotels in the market, insufficient information on hostel services, lack of legislative regulation for hostel operations) and threats (oversaturation of the market with hostel services, travelers' changing preferences toward more comfortable accommodations, the growth of the 2–3 star hotel segment, which offers an alternative to hostels, lack of government support, and a decrease in investment flows).</p> N.

The authors of the study considered standardization and certification systems of various levels, which today are an integral part of the activities of hospitality market participants. The article presents the main trends of the hotel and restaurant business market: active recovery of demand for hospitality services, combination of work on vacation («leisure' stays»), hyperpersonalization of demand, health care, which require additional efforts and funds from industry participants. An indisputable confirmation of the quality of services and management at the enterprise is compliance with standards and norms, the indicators of which are aimed at achieving the goals of sustainable development, the enterprise, the industry, the region and the country as a whole. The article examines the features of the ESRS, IFRS S1 and IFRS S2 standards, a set of Hotel Sustainability Basics indicators, GSTC industry criteria, and ISO standards. Standards that have been working for several decades remain relevant. They control quality in various areas. New problems contribute to the creation of new standards. The IFRS S1 and IFRS S2 standards, which were released just last year, aim to keep companies on track to meet the Sustainable Development Goals. The standards are designed to create trust and confidence in the activities of enterprises, to help find a common language regarding the impact of climate risks between investors and businesses. The authors present the main problematic points of standardization processes for the Ukrainian hospitality market and further prospects for the development of the industry. It is emphasized that compliance with standards of different levels and directions by hospitality establishments not only provides guarantees to consumers when making a decision to purchase a service, but also acts as a guarantor of stability and perspective for investors who decide to invest in new hotel and restaurant business projects. Such steps will help the fastest recovery and sustainable development of domestic enterprises in the field of hospitality. Domestic enterprises will be able to confidently compete in the global hospitality market.</p> N. H. Yakovlieva-Melnyk, V. V.

Particular attention is paid to the choice of materials, buildings orientation, constructive solutions, ventilation and lighting systems, and the integration of renewable energy sources. The analysis of modern architectural approaches that help reduce energy consumption and ensure the sustainability of the hotel and restaurant business is presented. The results of the study emphasize the importance of integrating energy-efficient technologies in the early stages of design and during the operation of buildings. The paper considers the main architectural aspects that affect the energy efficiency of hotels and restaurants and provides examples of modern solutions that allow for achieving high energy efficiency indicators. The purpose of this study is to investigate the impact of architectural solutions in the design and construction of hotel and restaurant business establishments on their energy efficiency. Based on this, its objectives are as follows: to characterize the impact of external factors of the location area of the establishment and its orientation relative to the cardinal points; to identify constructive opportunities to reduce heat loss; to analyze ventilation and air conditioning systems; to provide examples of the use of renewable energy sources; to prove the benefits of building management system automation; to determine the role of lighting system quality in improving energy efficiency; to analyze the use of environmentally friendly materials; to characterize modern energy-saving technologies and innovative materials; to analyze the impact of energy efficiency on business profitability. Investments in energy-efficient technologies are often perceived as additional costs that are not always a business priority. However, the long-term perspective shows the opposite: energy efficiency can have a significant impact on the profitability of hotels and restaurants. Energy-efficient buildings are becoming more attractive to guests who are increasingly paying attention to environmental aspects when choosing a place to stay or eat. The marketing advantage provided by energy efficiency certificates or participation in sustainability programs can be a significant factor in competing in the market. It is also worth noting that energy efficiency investments often have a short payback period. Due to reduced energy costs, such projects can pay off in 3-7 years, after which the company begins to receive a net profit from the saved funds.</p> A. V. Pogrebnyak, M. M. Kucher, O. V. Sabirov, A.
