Authors:   National Technical University «Kharkiv Polytechnic Institute», Kharkiv, Havrylova A. A.
Published: April 2024

The emergence of Big Data has made it possible to obtain more information about the customer and competitive base, as well as about market trends. Therefore, the desire of criminals to gain unauthorized access to this data also increases in direct proportion. However, not enough attention is paid to security issues of Big Data systems and their creation does not take into account the information security component. The purpose of the article is to develop approaches to the cyber protection of Big Data, which are stored and transmitted by telecommunication communication channels when responding to a request, namely their integrity and authentication. The main problems when working with Big Data are analyzed. Based on the results of the analysis of Big Data protection problems, a cryptographic transformation of data indexes when they are stored in the database and when transmitted in the form of hash codes is proposed to increase the efficiency of search by user requests. The expediency of using crypto-code constructions on elliptic curves of various types of modifications to form a pseudo-random substrate in order to increase the crypto-resistance of transmitted messages is proven. When forming hash codes, it is advisable to use modified elliptical codes, and under stricter conditions, the level of cryptographic resistance of authentication codes can be increased due to hybrid crypto-code constructions. A pseudo-random substrate can be represented by varieties that must equally ensure the necessary transformations and preservation of universality properties by the UMAC algorithm.

Authors:   Lviv Polytechnic National University, Lviv, Nyemkova O. A.
Published: April 2024

Microcontroller technologies are the basis for intelligent devices, so cybersecurity issues are important when ensuring the exchange of information between them. As these devices form a variety of intelligent systems, authentication becomes a key aspect of cybersecurity. This process distinguishes between legitimate and illegitimate devices, allowing legitimate devices to access system resources and reject requests from illegitimate ones. Today there is a problem of choosing an authentication factor for a large number of electronic devices of the same type in the information system. The purpose of this study is to find out the possibility of a programmatic approach to simulating a "biometric" authentication template. To solve the goal, it is necessary to implement a simulator of templates with the properties of biometrics in a programming language, to evaluate the distribution of distances between pairs of templates, and to evaluate the parameters of the generated sequences from the point of view of brute force probability. In this study, a solution to the problem is proposed, which combines the ideas of the biometric factor and the possibilities of fast software generation of authenticators for microcontrollers. The work is devoted to the evaluation of the model parameters of the simulator of dynamic bit patterns of authentication based on the generator of pseudo-random impulse Poisson sequences. The work highlights the basic principles of the simulator's functioning and the advantages of using dynamic templates to ensure cyber security of electronic devices built on the basis of microcontrollers. Estimates of the main parameters of the simulator model were performed. The results of the work are important for the development of security of electronic systems and means of authentication in the context of cybersecurity of microcontrollers.

A detailed analysis of the M/M/m model and the study of its main components allow a deeper understanding of the processes in mass service systems. The delay time in the M/M/m system is reflected in its direct impact on the quality of service and satisfaction of users of such networks
Mitigating partial content update issues on web pages through SPA parameter optimization
Authors:   State University of Information and Communication Technologies, Kyiv, Khlysta I. A.
Published: April 2024

The experience of recent years has shown that the number of active web applications developed according to the fundamental principles of single-page applications continues to grow steadily despite a decrease in the number of newly created ones. This indicates a shift in focus from the importance of developing anew to the necessity of maintaining, servicing, and optimizing the existing end product. Furthermore, with the advancement and improvement of web development technologies, the potential expectations of users increase, necessitating the provision of a worthy user experience and the enhancement of application competitiveness. A significant role in this process is played by the partial content update process on web pages, widely used in the development of single-page applications. Most modern JavaScript frameworks designed for client-side web development employ the «out-of-box» technique, thereby providing the developer with complete discretion in deciding on approaches to its application. However, the automatic use of the web page content update mechanism does not guarantee desired results and often leads to average or sometimes unsatisfactory values that could have been avoided. This article provides an analysis of the characteristics of the performance parameters of a single-page web application, explores alternative methods to solve the stated problem, investigates potential «problematic» areas of the client-side of applications, compares the functioning of content update mechanisms of the most popular JavaScript frameworks Angular and React.js, and formulates recommendations for optimizing the overall application performance. The article concludes with tables of Core Web Vitals metrics for evaluating the effectiveness of the conducted optimization. Finally, potential vectors for further research are proposed.

The traditional core of DOM (Document Object Model) and its formal representation in fDOM
Authors:   State University of Information and Communication Technologies, Kyiv, Zalyva V. V.
Published: April 2024

This article discusses the differences between two models of web documents: the traditional DOM (Document Object Model) and fDOM (formal DOM). The discussion begins with a description of Core DOM, which represents the structure of web documents as a hierarchical tree of nodes. Each node represents elements, attributes, and textual content, allowing for navigation, modification, and deletion of document components. The visual structure of DOM is illustrated using HTML code. The use of Isabelle/HOL, a higher-order logic system, for working with fDOM is then considered. This allows for the formalization of the mathematical properties of fDOM, ensuring their correctness and resistance to vulnerabilities. An example of code in Isabelle/HOL demonstrates how operations on web document elements can be defined and verified. The article also compares DOM and fDOM, highlighting differences in their approaches to representation and interaction with web documents. It is emphasized that while the traditional DOM provides a flexible interface for web documents, fDOM offers a more rigorous, mathematical representation, focused on precision and strictness. The discussion concludes with the advantages and disadvantages of fDOM. Among the advantages are formal verification, strong typing, consistent behavior, clear definitions, and enhanced security. However, increased complexity and development time, less flexibility, higher resource costs, and a steep learning curve are noted as disadvantages of fDOM. The conclusion emphasizes that fDOM offers a reliable, verified foundation for web applications but also introduces additional development requirements, making it particularly useful for applications where correctness and security are important.
Application of recommendation system in educational Field
Authors:   State University of Information and Communication Technologies, Kyiv, Khudik B. O.
Published: April 2024

The article is devoted to the issue of the application of recommender system technology in the educational sphere. It was determined that certain tasks of the educational field can be described in terms of recommendation systems: the user who is given a recommendation is the education applicant; the objects of his interest are disciplines from the catalog of optional disciplines, sources from the library of the educational institution, topics (or research area) of qualification papers, potential supervisors of qualification papers, external courses for the organization of self-education. A list of resources was created to determine the characteristics of the education applicants’ objects of interest and the education applicants themselves within the framework of formal education, and an analysis of their content and method of formation was carried out. The structure of the recommendation system has been developed; its feature is that each object of interest of the education applicant corresponds to a separate module of recommendations. At the same time, the recommendation modules use shared resources, including databases of the educational institution with direct information about the objects of interest and the education applicant, as well as survey databases consisting of general regular mandatory surveys for education applicants at the level of the educational institution and contextual surveys regarding objects of interest. A hybrid approach was chosen to form the recommendations. The structure of the system provides for the use of collaborative filtering for processing survey results, and data presented in the form of semi-structured or arbitrary texts in natural language is proposed to be processed using Natural Language Processing and Text Mining methods, which will allow taking into account semantically similar values of the characteristics of objects of interest and users and thus to improve the quality of the recommendation system.

Authors: Trubetskoi K. N. , Galchenko Yu. P. , Kalabin G. V.
Published: April 2024

The internal contradictions that affect the interaction of the techno- and biosphere during the intensification of subsoil development are considered. The necessity of timely ecologization of the technological paradigm of the development of subsoil use as one of the main elements of the technosphere and a natural transition to a new technological order corresponding to the characteristics of a post-industrial society has been substantiated. The causes of the modern systemic ecological crisis associated with the antagonistic form of interaction between man and nature have been indicated. This crisis can be overcome through the gradual ecologization of the technological paradigm in general and subsoil use in particular. The massive use of naturelike technologies contributes to the modernization of the technological order. It is this form of revolutionary transformation that opens the way for establishing coevolutionary interaction of systemic antagonists—man and the living nature of the Earth—based on the principles of parallel nondestructive development.

Authors: Volodin A. G.
Published: April 2024

This article considers the problem of population migration from Southeast Asia to Western European countries, on the one hand, and from China, India, and other Asian countries and territories to Southeast Asia, on the other. The formation of the model of metropolis−colony relations in Southeast Asia is shown; similarities and differences between the British and Dutch models of colonialism are revealed. The author analyzes the influence of Amsterdam’s imperial policy on the formation of the “Dutchness” of a cross-border identity, which had a significant impact on the model of the migration behavior of the inhabitants of the Dutch East Indies (modern Indonesia) and on the postcolonial interaction between the Kingdom of the Netherlands and independent Indonesia. The relationship between the economic development model of Indonesia and the migration activity of Indonesians, who increasingly prefer societies of vigorous economic growth of Northeast Asia and Australia to the former metropolis, is shown.

Authors: Jönsson Alexander , Aliboni Giacomo Carlo Ferdinando , Windmark Christina , Ståhl Jan-Eric
Published: April 2024

A continuously growing and mutating market with increasing demands on environmental sustainability, illuminated by unraveling environmental threats, highlights the need for greater resource efficiency in modern manufacturing industries. Machining has become pivotal in the pursuit of sustainability given its superior efficiency in manufacturing of metallic products. In theory, the efficiency of a machining operation is dictated by the material removal rate and chip formation behavior. However, this may also present additional challenges as chips can be difficult to evacuate from the workpiece, and cause chip carryover. Chip management aims to contain manufacturing costs by addressing this issue and simultaneously pursuing higher machining efficiency. Persistent chips trapped in internal cavities is particularly challenging and can affect quality, and result in costly re-manufacturing, scrapping of portions of produced volume. Effective chip management strategies is therefore crucial to avoid these problems. While there is established research on machining theory and chip removal, proposed solutions are often focused on a specific implementation and lack a holistic perspective on the phenomenon. This study aims to fill this gap in the knowledge by providing a strategic and practical application to tie together information that would otherwise be disaggregated. A case study was conducted to investigate the role of machining, and identify the source of chip carryover and its effect on subsequent production stages. Practical verification demonstrated the effectiveness of the proposed interventions in reducing production costs by decreasing the cycle time and reducing waste, and improving product quality. The future of sustainable manufacturing processes relies on the adoption of strategies and interventions that contribute to the efficiency and sustainability of the manufacturing industry. This study provides a valuable contribution to this effort.

Authors: Elnourani Mohamed , Johansen Kerstin , Öhrwall Rönnbäck Anna
Published: April 2024

Metal cutting industry, a key sector in manufacturing, is grappling with the transition to a “net-zero industry” to mitigate climate change and reach sustainable practices. Rare and exclusive materials make recycling and reusing cutting tools more pressing and necessitate efficient circular material flows. The purpose of this research is to explore how collaboration can facilitate circularity in the cutting tool industry. It examines the involvement of stakeholders and their roles in achieving a circular lifecycle for cutting tools. To investigate the interaction between metal cutting tools suppliers and Small and Medium-sized Enterprises (SMEs), this study used a mixed-methods approach that includes data from literature, interviews, and document study. Empirical data is gathered to investigate the factors driving circularity and to identify important participants in the lifecycle of cutting tools. The study revealed challenges to the current situation including underutilization of tools due to the absence of a standardization process and subjective operator judgment, as well as lack of traceability of the tools both internally at SMEs and between the stakeholders. Moreover, by mapping the current actors, the study found cutting tool traceability, undirected decision-making throughout tool lifecycles, and limited awareness of circularity dimensions are key challenges. To handle these challenges. 9Rs circular economy framework used to investigate the possible role of collaboration emerges as a vital enabler for circularity, with SMEs playing a significant role. Moreover, the involvement of machine operators, often overlooked actors, is found to be crucial in influencing circular outcomes. Digital solutions and collaborative strategies that involve CNC machine suppliers and intermittent refurbishing business are pivotal in overcoming the challenges identified, namely, traceability and human subjectivity in tool condition assessment. The study demonstrates that technology providers, intermediary refurbishing businesses, SMEs and other stakeholders operating in the metal cutting tools sector must be involved throughout their lifetime to avoid suboptimal results, exchange information, and inspire industrial actors to support the circular economy.

This paper highlights current challenges and several focus areas on which the aerospace manufacturers have started to work on and will have in focus for the next 5–10 years ahead. Differences in approach have been identified between early product development phases with radical innovations and more advanced and mature product development. The stakes and priorities are different and it is reflected on how the companies are working with sustainability today. There is a need to balance efforts between developing the right future products, and also improving current ones, to lead the sustainability transformation in the aerospace industry.
Key Performance Index for Creating an Integrated and Sustainable Academy – A University with the Ability to Meet Future Needs and Challenges Identified in Society and Industry
Authors: Ståhl Jan-Eric , Andersson Joel , Ahadi Aylin
Published: April 2024

Key performance indexes (KPIs) in various forms have always been used in one way or another in the production and processing of raw materials. The need for KPIs was accentuated with the advent of industrialism in the western world. The way and strategy of manufacturing industrial products has been divided into several so-called developmental transformations. Primarily after the depression of the 1930s and after the Second World War, a way of working and a basic view was gradually created that has resource efficiency and goal achievement as a fundamental idea. This publication describes how KPIs can be used in higher education to create a sustainable academy to meet challenges in industry and society over time. This with a focus on sustainability and continuity as well as a strategic integration between the academy’s various missions. These missions consist of teaching, research and collaboration. Furthermore, according to the Higher Education Ordinance, teaching shall rest on a scientific basis and, when appointing senior positions, equal weight shall be attached to the merits that can be linked to teaching and research. In addition to teaching and research, collaboration must be conducted with the surrounding society. Society places increasing demands on the knowledge conveyed in teaching to harmonize with current needs and to prepare for future needs and challenges. A starting point for the publication is that needs and challenges can best be met through a conscious and strategic integration between the academy’s various missions. Another aspect that is highlighted in this publication is the importance of strengthening the collaboration between basic subjects and more applied and industry-related subjects, which provides renewal in the applied subjects at the same time as the basic research can be utilized at a higher rate. In an industrial perspective, a more continuous TRL scale is obtained, which provides a more effective implementation of research results. A development path that strengthens the Academy’s mission areas is the principle of affiliation of personnel from industry and other sectors of society and increased admission of industrial doctoral students and other external doctoral students. In order to monitor the development of the respective mission areas of academia and its integration, the use of KPIs will be addressed. A discussion of their benefits will be highlighted but also the associated difficulties, especially when conditions change. The conducted literature study shows that there are very few or rather no found publications dealing with KPIs for the integration of the Academy’s different missions. KPIs are well developed for higher education in terms of its implementation and associated economics. Corresponding published work related to KPIs in research deals primarily with conventional academic bibliometrics.
Bridging Skill Gaps – A Systematic Literature Review of Strategies for Industry
Authors: Braun Greta , Rikala Pauliina , Järvinen Miitta , Hämäläinen Raija , Stahre Johan
Published: April 2024

Industries are facing extensive needs for both digital and green transitions. Adding to the challenges, environmental crises, a recent pandemic, and military conflicts are forming a “perfect storm”. Consequently, companies need to rapidly adapt to new requirements and create resilient, sustainable, and human-centric solutions, a combination often called industry 5.0. A highly skilled workforce is required, where “right-skilled” employees will drive successful technology adoption and business transformation. Unfortunately, many companies face skill gaps, causing a slowdown in productivity and sustainable development. Fully bridging the skills gaps is not achievable only through recruiting of young talent. Ongoing demographic changes are causing a decrease in the working population, making hiring harder and increasing industry competition for existing talent. Upskilling existing workforces is a natural solution to bridge the skill gaps. This paper presents the results from a systematic literature review conducted in January 2023 using the PRISMA method. The study included 40 articles and thematically analyzed solutions for bridging skill gaps. Identified solutions address employers, employees, education providers, students, job seekers, researchers, and policymakers. Results highlighted that collaboration between stakeholders potentially helps bridge skill gaps in industry. Employees requiring upskilling need to understand what skills are relevant, and how they can absorb state-of-the-art knowledge and learn new skills. Employers should support their employees, supply relevant resources, and define clear skill requirements. Education providers on the other hand, must adapt to changing industrial business needs and gradually adapt traditional curricula, in parallel with regular education. Academia and industry collaboration is vital. Thus, flexible and rapid training and re-training solutions and approaches are needed, not just on-off activities. The main contribution of this paper is to review actions that employers, employees, education providers, researchers, students, job seekers, and policymakers need to take to bridge skill gaps. This analysis can be used by industrial practitioners, policymakers, and education providers to work with strategies to bridge skill gaps in their business and in their work. The theoretical implication of this work is the acknowledgement of the existing skill gap and the synthesis of actions for stakeholders. The article can be used to set future research directions to get closer insights into the derived challenges and success factors when bridging skill gaps.

A mathematical model of the gravitational potential of the planet taking into account tidal deformations
Authors: Shatina А. V. , Borets A. S.
Published: April 2024

Objectives. This paper investigates the gravitational potential of a viscoelastic planet moving in the gravitational field of a massive attracting center (star), a satellite and one or more other planets moving in Keplerian elliptical orbits relative to the attracting center. Celestial bodies other than a viscoelastic planet are modeled by material points. Within the framework of the linear model of the theory of viscoelasticity, the problem of finding the vector of elastic displacement has been resolved. Traditionally, a solid body model is used to determine the Earth’s gravitational field, while tidal deformations are taken into account in the form of small corrections to the coefficients of the geopotential model. In this work, the viscoelastic ball model is used to take into account tidal effects. The relevance of the research topic is associated with high-precision forecasting of the movement of artificial satellites of the Earth, high-precision measurement of the Earth’s gravitational field.Methods. In this study the asymptotic and analytical methods developed by V.G. Vilke are used for mechanical systems containing viscoelastic elements of high rigidity, as well as methods of classical mechanics, mathematical analysis. The graphs were plotted using the Octave mathematical package.Results. After resolving the quasi-static problem of elasticity theory by calculating triple integrals over a spherical area, a formula for the gravitational potential of a deformable planet was obtained. In addition, the gravitational potential of the Earth was also calculated taking into account solid-state tidal effects from the Moon, Sun, and Venus at an external point. Graphs were constructed to show the dependence of the Earth’s gravitational potential on time.

Conclusions. The theoretical and numerical results established herein show that the main contribution to the gravitational potential of the Earth is made by the Moon and the Sun. The influence of other planets in the solar system is small. The value of the gravitational potential at the outer point of the Earth, taking into account tidal effects, depends both on the position of the point in the moving coordinate system and on the relative position of celestial bodies.

Das soziale Setting von Radikalisierungsprävention in Haft lässt sich als triadische Struktur aus Justizbediensteten, externen pädagogischen Fachkräften und Inhaftierten untersuchen. Anhand ethnografischen Datenmaterials gehen wir der Frage nach, welche Akteurskonstellationen der pädagogischen Arbeit zugrunde liegen und in welcher Weise sie die konkrete Umsetzung der Radikalisierungsprävention beeinflussen. Es wird deutlich, dass die Triade ein Spannungsfeld unterschiedlicher Interessen und Sinnkonstruktionen darstellt, unter anderem was den Umgang mit gesellschaftlicher und gefängnisinterner Sicherheit betrifft. Externe Akteur*innen im Strafvollzug müssen ihre Beziehungen sowohl zu den Gefangenen als auch zu den Bediensteten fortwährend ausbalancieren, um die Deutung und die alltägliche Einbettung ihrer Arbeit innerhalb der Sozialstrukturen einer Justizvollzugsanstalt verhandeln zu können und handlungsfähig zu bleiben.

Im Artikel werden Befunde zu Hausbesuchen in kindesschutzrechtlichen Abklärungen in der deutschsprachigen Schweiz präsentiert. Hierfür wurden Interviews mit Fachkräften, Falldossiers und teilnehmende Beobachtungen mit der Grounded Theory ausgewertet. Im Anschluss an die konstruktivistische Soziologie sozialer Probleme wird davon ausgegangen, dass der Rechtsbegriff einer „Kindeswohlgefährdung“ in einer fallspezifischen Problemarbeit konkretisiert werden muss. Erstens zeigen wir auf, wie der Hausbesuch in dieser Problemarbeit als eine Technik der Sichtbarmachung elterlicher Sorge fungiert. Zweitens legen wir dar, dass Abklärende die familiale Privatheit in den Dimensionen Räume, Rhythmen und Hierarchien in den Blick nehmen. Diese mit dem Wohl des Kindes in seiner Familie assoziierten Dimensionen werden primär in situ erfasst. Die Verantwortbarkeit des elterlichen Handelns wird dabei daran beurteilt, ob das Kind im Kontext seiner häuslichen Sphäre einem als ausreichend interpretierten pädagogischen Moratorium unterstellt ist. Hierin ist die Problemarbeit insbesondere von der Bindungstheorie geprägt.

Wie sähe eine Welt ohne Abweichung in der Zukunft aus? Oder ist dieser Zustand schon längst eine Möglichkeit? Der Aufsatz versucht darauf eine Antwort zu finden, denn mit der Durchdringung des Alltags durch digitale Technologien und ihrem Potenzial, Verhalten, Wünsche und das Zusammenleben der Menschen zu beeinflussen und zu kontrollieren, stellt sich diese Frage durchaus. Denn eine Qualität dieser Technologien und der dahinterstehenden Plattformen ist die Möglichkeit der sozialen Kontrolle. Diskutiert wird daher, welche Formen soziale Kontrolle in der Digitalisierung annimmt, wie man die gesellschaftlichen Bedingungen theoretisch beschreiben kann und was eine konsumsoziologische Betrachtung dieser so gestalteten sozialen Beziehungen erklären kann. Es werden vier Modi vorgestellt, mit denen die neuen Formen sozialer Kontrolle in der Digitalisierung beschrieben werden können – und schließlich auch eine Antwort auf die Frage nach einer Welt ohne Abweichung gegeben.

Objective: The main focus of this study is to explore the clinical effects of 3D endoscopy in total thyroidectomy and central lymph node dissection. Methods: Eighty patients undergoing thyroid cancer total thyroidectomy at Shengjing Hospital, China Medical University, from February 2017 to March 2018, were divided into two groups. The experimental group, consisting of 40 patients, underwent treatment using 3D endoscopy, while the control group, also comprising 40 patients, underwent treatment using 2D endoscopy. A comparison was made between the two groups in terms of the incidence of adverse reactions and relevant clinical indicators. Results: Whether in terms of surgical time, blood loss, or postoperative drainage, the experimental group performed better than the control group. Additionally, there were no significant differences between the two groups in postoperative hospital stay, lymph node dissection frequency, lymph node metastasis quantity, and cost. Regarding the incidence of adverse reactions, the experimental group and the control group were 7.50% and 30.00%, respectively, with the former significantly lower than the latter, and the difference between the two groups was statistically significant. Conclusion: 3D endoscopy exhibits good clinical effects in total thyroidectomy and central lymph node dissection, effectively improving patient outcomes, and is worthy of promotion.

У статті, спираючись на аналіз наукових поглядів вчених та норм чинного законодавства, виділено систему правовідносин, які складають предмет підтримки та розвитку бізнесу в умовах воєнного стану. Акцентовано увагу на тому, що відповідний предмет обумовлюється тими публічними інтересами, які можуть задовільнити представники бізнесу. Обґрунтовано, що предмет підтримки та розвитку бізнесу – це конкретна сфера правовідносин, на яку впливають відповідні заходи, наприклад: спрощена процедура створення суб’єкта підприємницької діяльності, удосконалення податкового регламентування на основі гнучкої системи оподаткування, інформаційна підтримка результатів підприємницької діяльності (організація виставок, ярмарків, у тому числі міжнародних), організація та проведення конкурсів на отримання грантів на бізнес, що пов’язаний із забезпеченням потреб безпеки та оборони (виробництво дронів тощо) та ін. Узагальнено, що розглядуваним предметом можна назвати сфери правовідносин за участі, з одного боку, суб’єктів підтримки та розвитку бізнесу, а з іншого – потенційних чи зареєстрованих суб’єктів провадження бізнесу, діяльність яких сприяє задоволенню публічних інтересів у подоланні наслідків збройної агресії, у тому числі соціально-економічному розвитку держави.

La relación entre dos vecinos de habitación. Una mujer que necesita saber cuánto mide cada elemento que la rodea. Un grupo de personas que pierden objetos e ideas. Un hombre y el gato que le enseñó a leer. Los 24 cuentos que componen Un año de servicio a la habitación son historias que nos acercan a la vida de todos los que cohabitan un mismo lugar: huéspedes temporales, residentes y personal empleado entrecruzan sus historias en un hotel. Andrea Chapela (Ciudad México, 1990). Estudió Química en la UNAM y después un MFA en escritura creativa en español en la Universidad de Iowa. Desde octubre de 2017 vivió en Madrid dos años con una beca del Ayuntamiento para estudiar en la histórica Residencia de Estudiantes.
