Prospects for the development of blockchain technology in corporate information systems
(2025-05-27) Tulashvili, Yuriy; Lukianchuk, Iurii; Kosheliuk, Viktor
Over the past decade, blockchain technology has undergone rapid development and is recognized as one of the pivotal information technologies driving industrial transformation. Today, blockchain technology offers a promising solution to the problems faced by corporate information systems. Namely, with the help of appropriate measures of anonymization and preservation of confidentiality, the blockchain enhances data security, reduces the risk of unauthorized access, and ensures user privacy in corporate systems. Blockchain technology increases transparency, allowing users to monitor and verify the content of information, assess the integrity of data stores. In recent years, blockchain has become a subject of interest for state governments, multinational corporations, and major financial institutions. Today, considerable attention is paid to the development of private (corporate) blockchains. This article examines the prospects and development of blockchain technology in corporate information systems. The study is aimed at providing additional clarity regarding the concept of blockchain applications in corporate information systems. Existing enterprise applications cannot operate seamlessly with traditional transactional requirements when integrating blockchain technology. Therefore, they will have to be modified with inclusion in the existing data storage for asynchronous interaction with distributed nodes of the blockchain. A scheme of the principle of interaction of nodes-storages that support data synchronization and their current states are proposed. This scheme is based on a blockchain structure centered around cloud storage as a corporate document circulation system. Consensus to include a new entry-Byzantine fault tolerance. Blockchain nodes receive a parametric weight for decision making.
Orchestrating honeypot deployment in lightweight container platforms to improve security
(2025-02-01) Tulashvili, Yurii; Kosheliuk, Viktor
A significant evolution has occurred in the architectural and infrastructural domains of web applications over the past several years. Monolithic systems are gradually being superseded by microservices-based architectures, which are now considered the de facto standard for web application development owing to their inherent portability, scalability, and ease of deployment. Concurrently, the prevalence of this architecture has rendered it susceptible to specialized cyberattacks. While honeypots have proven effective in the past for gathering real-world attack data and uncovering attacker methods, their growing popularity has made them a specific target for cyberattacks. Traditional honeypots lack the flexibility of microservices architecture. Honeypots have proven effective in gathering authentic attack data and analyzing attacker tactics. The core idea that honey traps help identify malicious packets with minimal effort to remove incorrect alerts is preserved. In addition to identifying and documenting specific attack methods used by intruders, this system helps thwart attacks by creating realistic simulations of the actual systems and applications within the network. This effectively slows down and confuses attackers by making it difficult for them to gain access to real devices. This paper presents a groundbreaking approach to honeypot management within cybersecurity, utilizing virtual clusters and a microservice architecture to significantly improve the effectiveness of threat detection. To conduct our research, we initially surveyed the internet to pinpoint container and container management systems operating on standard ports that might be susceptible to attacks. The monitoring of the instrumented approach generated a massive dataset, enabling researchers to make significant inferences about the behavior and goals of malevolent users. We advocate for the implementation of honeypots on lightweight distribution orchestration tools installed on Ubuntu servers, situated behind a meticulously crafted gateway and operating on standard port configurations. In light of the scan outcomes, we recommend the deployment of honeypot orchestration on streamlined distributions. To better protect your systems based on our scan results, we recommend implementing honeypot orchestration for easier deployment and management. By deploying honeypots on lightweight operating systems, you can optimize resource usage and improve performance while maintaining essential capabilities. These capabilities include monitoring attack patternson vulnerable systems and analyzing the security measures implemented by those responsible for managing exposed systems.

(2024-04-27) Tulashvili, Yurii
The new concept of humanizing society, founded on the priority of personality development through socialization processes, opens new perspectives for citizens with visual impairments in Ukrainian society. The article analyzes the issue of social adaptation of this category of people through inclusive education, which encompasses preschool, general, and vocational training. The historical, philosophical, psychological, and methodological aspects of implementing an integrative approach to inclusive education for visually impaired individuals are considered. The study emphasizes the importance of the “principle of equal opportunities” in education for children and youth with functional limitations, focusing on the integration of such individuals into the general educational process. It underscores the need for a societal attitude shift towards children with special educational needs and the support for the idea of inclusion at the state level, involving school administrators, educational staff, parents, and other participants in the educational process. The psychological and pedagogical support of children with visual impairments within the context of inclusive education, playing a key role in the development of Ukraine’s modern educational system, is distinguished by its multidisciplinary approach. This support ensures the preparation and psychological readiness of all participants in the educational process for cooperation with children with health issues and includes the prevention and correction of secondary developmental deviations in such children. Special attention is paid to the role of social and pedagogical work in the development of a child with disabilities in accordance with the general patterns of child development, considering secondary symptoms related to abnormal social development. The article investigates the main approaches to implementing inclusive education in the educational space of Ukraine. The author examines the normative legal acts concerning the integration of people with special needs and their impact on the development of democracy. Additionally, an overview of the experience of organizing education for people with visual impairments in Ukraine and abroad is provided. The authors of the article highlight the need for support of regional rehabilitation and social protection programs for people with visual impairments, the creation of scientific-methodological resource centers for inclusive education, and the integration of such children into general education institutions. The conclusions of the study underline that addressing issues of accessibility, inclusion, and humanization of societal relations towards visually impaired individuals will contribute to their successful socialization and professional training, reflecting modern approaches to education and vocational training for blind and visually impaired individuals. The importance and prospects of implementing inclusive education in Ukraine’s educational space are demonstrated and significant for educators, lecturers, and students of pedagogical and technical universities, as well as education and science professionals.
Investigation of Cylindrical Particles Sphericity and Roundness Based on the Extreme Vertices Model
(Springer Nature Switzerland, 2024) Заболотний, Олег Васильович; Гульчук, Юрій Миколайович
In this scientific investigation, the article's authors have created a three-dimensional computer simulation model to explore the sphericity and roundness of elements, specifically particles. The authors elucidated the detailed calculation of the sphericity of elements and roundness of elements for cylindrical particles through the application of the extreme-vertex 3D model. Based on the proposed extreme vertex model theory, the points at which linear constraints intersect were optimized, allowing for the maximum approximation of the form factor to unity. Furthermore, the proposed theory of extreme vertices in the context of modeling elements, particularly in voxel-based modeling, is of significant importance in defining the boundaries and limits of objects in three-dimensional space. Moreover, it was discovered that this idea holds importance in the context of the simplex-complex method, a commonly employed algorithm for addressing linear programming problems. Additionally, correlations between the sphericity and roundness of elements and the particle diameter were examined, enabling the prediction of particle shape. This is because the obtained sphericity values mostly approximate 1, which implies that the elements have a spherical or nearly spherical shape.
Optimization of 3D Computer Model Parameters for Spherical Elements Modeling
(Springer Nature Switzerland, 2024) Заболотний, Олег Васильович; Гульчук, Юрій Миколайович
The scientific chapter discusses the simulation of spherical elements using a developed computer model. We documented the primary combinations of spherical particles that occur during filling in the hopper. The modeling revealed that the most common combination for spherical elements consists of three balls, forming an equilateral triangle in the cross section passing through the centers of the balls. In the case of a structure with four spherical balls, connecting their centers creates a rhombus in the cross section. Notably, this combination generates two smaller equilateral triangles within the rhombus, influencing the process of pushing the spherical balls apart. This process, in turn, facilitated the observation of contact between spherical elements and established the stable position of each individual particle.
Improvement of Processes for Obtaining Titanium Alloys for Manufacturing Parts with Design Elements
(Springer International Publishing, 2021-11-18) Заболотний, Олег Васильович; Гульчук, Юрій Миколайович; Ilchuk, Nataliia
The article presents a systematic block diagram for manufacturing TiAl titanium alloys. Based on the developed block diagram of TiAl components, the main already known stages of powder metallurgy manufacturing technology were improved. Based on the obtained chemical reaction of structurally inhomogeneous materials, the intermetallic phase relationship of titanium aluminides was revealed. It is studied that in the zone of interaction of the composition of titanium and aluminium components, a certain thickness of the transition layer is formed, which practically does not change with increasing exposure time. The crystallization process of inhomogeneous TiAl materials was studied in more detail using the constructed crystal lattice of titanium alloys. As a result, the formation of an atomic grid in space was observed. It should also be noted that the recognition of individual areas in microstructural images was carried out using the Smart-eye software package. The microscopic analysis allowed us to predict the main structural characteristics of TiAl components. In particular, to carry out more detailed control of the particles of TiAl components, their density, porosity, relationships with each other, the shape and size of TI and Al powders. The structure of the interaction of TiAl materials and the interpolation dependence of the formed intermetallic layer are also presented. Based on the conducted research, the quality indicators of parts with structural elements, particularly gears, have been improved.
Study of the Porosity Based on Structurally Inhomogeneous Materials Al-Ti
(Springer International Publishing, 2021) Заболотний, Олег Васильович; Ilchuk, Nataliia; Гульчук, Юрій Миколайович
A technology for forming structurally inhomogeneous materials of Al-Ti samples has been developed. The components of the initial mixture were calculated based on the bulk of real powders, taking into account the mass, stoichiometric coefficients of the original components, the purity, and the bulk density. The microstructure of structurally inhomogeneous materials samples was studied using application programs. Besides, image recognition is performed at various magnifications before etching and after etching. The main properties of Al-Ti materials at different temperatures are obtained. An interpolation of the porosity dependence is constructed based on theoretical and experimental data. It is proved that the granulometric composition of structurally inhomogeneous materials has been improved based on the correct percentage of the initial mixture. The dependences of porosity on pressure and melting temperature for manufacturing structural parts are substantiated and constructed. Thus, there is reason to argue that improving the granulometric composition of Al-Ti based on a correctly selected percentage of the initial mixture, taking into account the further process of forming structurally inhomogeneous materials, allows to control such a parameter as porosity, as well as to study the physical and mechanical properties in the manufacture of various structural purposes parts to predict their structures.
