FEATURES OF THE INFLUENCE OF SOVEREIGNTY ON THE LEVEL OF MANIFESTATION OF INTERPERSONAL TRUST IN YOUNG PEOPLE
Authors: Kolomiiets Lesia , Shulga Galyna , Lebed Iuliia
Published: February 2025

The article analyses the results of a study of empirical indicators of the features of the influence of sovereignty on the level of manifestation of interpersonal trust in adolescents. It is determined that the formation of personal boundaries in adolescence is extremely important for the harmonious development of the individual, since it is relevant for personal sovereignty, sovereignty of psychological space, which affects the level of self-esteem, style of behaviour, and life in the future, and the level of awareness of self-worth and uniqueness. In adolescence, attention is paid to the proper development of self-awareness, the formation of a system of values, especially interpersonal interaction, since developed interpersonal trust contributes to the development of communication skills, has a positive effect on emotional well-being, determines the choice of optimal life strategies, harmonises social experience, and forms emotional stability. Developed interpersonal trust in adolescence is the key to creating optimal conditions for professional development, self-affirmation, and self-realisation of the individual. In the context of the study, the main definitions are understood as follows: Personal sovereignty is the ability to control and protect the psychological space, which is manifested in maintaining the autonomy of the individual, its resistance to external influences, and the ability to build harmonious relationships with others; interpersonal trust is a certain attitude towards others, with the aim of harmonising social relations. The study involved 60 people; the average age of the subjects was 20.7 years. It was empirically determined that the indicators of psychological space sovereignty in adolescents have a predominantly average level of severity, which indicates certain difficulties in the subjects in protecting basic personal boundaries, since their efforts are more aimed at protecting the cognitive and behavioural aspects of their space than at protecting physical boundaries. The lowest level of trust is “trust in oneself,” and the highest is “trust in other people,” which indicates an imbalance between internal and external trust and dependence on external approval. The level of interpersonal trust is associated with a sense of security and confidence in the intentions of others, while a high level of psychological sovereignty forces a person to increase control over their boundaries and to be cautious and alert, which, although it creates a sense of security, limits the network of social contacts and increases feelings of isolation.

Published: February 2025

This research utilizes LDPE plastic pyrolysis residue and boiler crust ash as additives in asphalt modification to improve the hydrophobic properties of asphalt. Tests were conducted with time variations of 15, 30, 45, 60, and 75 mins. Contact angle measurements of asphalt mixtures, with the addition of LDPE plastic pyrolysis residues and boiler scale ash, as well as asphalt mixtures with the addition of LDPE plastic pyrolysis residues and silica, resulted in contact angle values greater than 90°, indicating that the asphalt mixtures possess hydrophobic properties. Characterization results using FTIR analysis showed the presence of C-H, O-H, Si-O-Si, and Si-O functional groups in the modified asphalt samples. The modification of asphalt with these additives can enhance its hydrophobic properties.

Published: February 2025

In the nuclear sector, secure transportation of radioactive materials is crucial in the nuclear sector, and cask design and analysis are crucial for maintaining fuel integrity. Peak cladding temperature (PCT) is a significant factor in fuel failure likelihood. This research provides a thorough approach to designing and analysing nuclear transportation casks, focusing on PCT. Advanced computer techniques are used in the study, which includes a number of variables including the thermal properties of the cask and external heat sources. In this work, a composite PCM made of polyethylene glycol (PEG) and octadecanol is employed to provide equal heat transfer. The proposed composite PCM is reinforced by (Carbon Nano Tubes) CNTs to ensure homogeneous heat conduction within the PCM particles. The thermal behaviour of the cask is simulated using ANSYS, which takes into consideration conduction, convection, and radiation heat transfer among other aspects. The PCT for spent fuel assemblies for light water reactors operating in helium settings with varying decay heat loads and temperature boundary circumstances was calculated using these simulations. Finally yet importantly, the outcome has been validated by comparison with related studies.
Carbon Footprint Principles and Challenges in Transport Logistics
Authors: Steger-Jensen Kenn , Hvolby Hans-Henrik , Vestergaard Sven , Neagoe Mihai , Svensson Carsten
Published: February 2025

Logistic operators are under pressure from consumers and governments to reduce the carbon footprint impact. Operators need increased focus on reducing the carbon impact and calculating their actual carbon emissions. EU's Emissions Trading System comes into force from 2027 and works on the 'cap and trade' principle. A cap is a limit set on the total amount of greenhouse gases that logistic operators may emit. Therefore, there is a need to develop a roadmap and action plans to reduce emissions, which will drastically impact the logistic operators. The paper brings forward current standards, frameworks and principles as well as examples of carbon footprint calculations in last-mile transportation.
A Comparative Evaluation of Augmented Reality Indoor Navigation versus Conventional Approaches
Authors: Macháč Tomáš , Hořejš Petr , Šimon Michal , Šimerová Andrea
Published: February 2025

In the context of Industry 4.0, augmented reality (AR) is becoming a key element for innovations in the field of lifetime usability of products and optimisation of production processes. Its integrated use outdoors via GPS and Simultaneous Location and Mapping (SLAM) indoors with a focus on inertial technologies enables precise positioning and efficient navigation in industrial environments. The aim of this study is to test the user-friendliness of the proposed indoor navigation system using inertial sensors. The AR application provides indoor navigation between defined points of interest representing key locations. ARCore and ARFoundation were used for development. Participants are tested using three different approaches to orientation in the environment. Their task is to evaluate the user-friendliness and compare the use of a smartphone with an ARNAV app, 2DMAP with visual elements, and variants without wayfinding support "BLIND". User acceptance is validated using a standardized SUS questionnaire. The evaluation results show similar perceptions of the system among most respondents, except for the need for technical support and the presence of inconsistencies, where the ARNAV group showed different opinions, indicating the need for optimisation in these specific areas to improve the user experience. In line with other studies the results suggest that despite advances in augmented reality, there is still a lack of added value, especially for inexperienced users. Despite the number of studies available, user testing of the proposed systems remains poorly carried out, with the emphasis more on functional verification. The results of the study suggest that the low variety and simplicity of tasks in the studied environment limits significant differences in the perception of AR navigation. Future research should focus on the use of augmented reality in complex environments and in solving more complex tasks.

Published: February 2025

The article is devoted to the study of the adhesive interaction of restorative compositions with shell limestone as a highly porous material of complex structure. The key physicochemical and mechanical factors determining adhesion are analyzed, including molecular forces, hydrogen bonds, electrostatic interactions, acid-base interactions, as well as the effect of humidity on adhesion. Elements of fractal geometry are used to describe the processes of adaptation of compositions to porous surfaces, a criterion of ideal adhesive contact is introduced. Models of structure formation are considered, including the Smoluchowski equation, diffusion-limited and cluster-cluster aggregation. It is shown how optimization of the restorative composition due to the selection of the necessary fractal parameters can improve its adhesive characteristics. Recommendations are given for the use of various methods for optimizing adhesion processes in restoration. It is also possible to use the obtained results in modern additive technologies.
Für eine durchgreifende Reform des schweizerischen Gesundheitswesens
Authors: Bürgenmeier Beat , Stalder Hans
Published: February 2025

Das Schweizer Gesundheitssystem weist trotz eines grossen Budgets, einer guten medizinischen Dichte und der unbestreitbaren Qualität der praktizierten Pflege zahlreiche Schwächen auf, die durch die Covid-19-Pandemie noch verschärft wurden. Vorschläge, die sich ausschliesslich auf Kostensenkungen stützen, können die Probleme im Gesundheitswesen nicht allein lösen. Das vorliegende Buch gibt der Debatte über die Reformen dieses Gesundheitssystems neue Impulse, indem es die Interessen der verschiedenen beteiligten Akteure – Angehörige der Gesundheitsberufe, Versicherte und Krankenkassen – analysiert, um die Patientinnen und Patienten wieder in das Zentrum der Gesundheitsversorgung zu stellen. Die Autoren – ein Arzt und ein Ökonom – schlagen einen interdisziplinären Ansatz, neue Formen der Finanzierung und Bezahlung sowie eine unabhängige Qualitätskontrolle vor. Dieser Ansatz zielt auf eine grundlegende Reform des Schweizer Gesundheitswesens ab und richtet die Aufmerksamkeit auf ethische Aspekte wie Solidarität, Fairness und gleichen Zugang zur Gesundheitsversorgung. Er empfiehlt, das Schweizer Gesundheitssystem in Form von Netzwerken (z.B. Medical Homes) zu organisieren, wie sie mancherorts bereits mit Erfolg praktiziert werden. Dadurch wird es auch einfacher, die ausufernde Bürokratie einzudämmen.

Higher-Order Meta Distribution Analysis of Wireless Systems with Application to the Reliability of UWB THz Networks
Authors: Monemi Mehdi , Rasti Mehdi , Mousavi S. Ali , Latva-aho Matti , Haenggi Martin
Published: February 2025

Communication reliability, as defined by 3GPP, refers to the probability of providing a desired quality of service (QoS). This metric is typically quantified for wireless networks by averaging the QoS success indicator over spatial and temporal random variables. Recently, the meta distribution (MD) has emerged as a two-level performance analysis tool for wireless networks, offering a detailed examination of the outer level (i.e., system-level) reliability assessment versus the inner level (i.e., link-level) reliability thresholds. Most existing studies focus on first-order spatiotemporal MD reliability analyses, and the benefits of leveraging MD reliability for applications beyond this structure remain unexplored, a gap addressed in this paper. We present wireless application examples that can benefit the higher-order MD reliability analysis. Specifically, we provide the analysis and numerical results for a second-order spatial-spectral-temporal MD reliability of ultra-wideband THz communication. The results demonstrate the value of the hierarchical representation of MD reliability across three domains and the impact of the inner-layer target reliability on the overall MD reliability measure.

Dado el crecimiento de la población en edad de trabajar, la tasa de ocupación (TO) se mantuvo estable en la coyuntura reciente, ubicándose en el 57,5 % en el último trimestre móvil, con una notable diferencia entre el área urbana (59 %) y las otras cabeceras y áreas rurales (55,9 %). En términos de posición ocupacional, el empleo asalariado mostró una recuperación durante el segundo semestre de 2024, con un crecimiento anual del 2,5 %, mientras que el no asalariado se mantuvo estable en dicho periodo, lo que impulsó una reducción en la tasa de informalidad que llegó hasta el 55,6 % en noviembre de 2024. Esta evidencia estaría mostrando una posible recomposición de la ocupación, en favor de trabajos de mayor calidad. Otros indicadores de demanda laboral, como las vacantes, han tenido una tendencia negativa en el último año; sin embargo, todavía se encuentran en niveles levemente superiores a la prepandemia; de forma similar, las expectativas de contratación se encuentran estables y aún positivas. Por su parte, la tasa de participación laboral (TGP) se ha mantenido relativamente estable durante el último año; no obstante, en el último trimestre se evidencia una reducción en la oferta laboral en todos los dominios. Esta caída en la participación se presenta junto con un incremento en los salarios reales mensuales. En línea con la menor participación laboral, se evidenciaron reducciones de la tasa de desempleo (TD) durante los últimos meses, especialmente en el otras cabeceras y áreas rurales. A nivel nacional, en el trimestre terminado en noviembre se redujo hasta el 9,8 %. Los pronósticos de la TD para 2025 sugieren una estabilidad relativa. Específicamente, se espera que la TD urbana se ubique a finales de 2025 entre el 8,5 % y el 11,6 %, con un valor más probable del 10 %. Por su parte, la TD del agregado nacional se proyecta entre el 8,3 % y el 11,4 %, siendo un 9,8 % la cifra más probable. Estos pronósticos reflejan, en conjunto, la dinámica observada y esperada en la actividad económica. Además, se prevé que la brecha de la TD continúe cerrándose durante 2025, con una tasa de desempleo no inflacionaria (Nairu) promedio del 10,5 %, lo que sugiere un promedio de -0,5 puntos porcentuales (pp) levemente más negativo que lo estimado en el Reporte anterior, pero en línea con la estabilidad del mercado laboral. Como es usual, este Reporte se divide en dos secciones. La primera analiza en detalle los hechos coyunturales del mercado laboral resumidos arriba. En la segunda se presenta un análisis de los efectos que el incremento en el costo del entrenamiento tuvo en la demanda de aprendices en Colombia durante 2014, año en el que dicho costo pasó del 75 % al 100 % de un salario mínimo (SM). Se encuentra que dicho incremento afectó la demanda de aprendices negativa y significativamente, en especial para aquellas firmas que no estaban obligadas a contratarlos

The article presents the results of determining the accuracy of the shape of the cross-section and obtained numerical values of the statistical characteristics of dispersion of deviations from the roundness of the surface of the cylinder sleeve of the telescoping boom of the KTA-25 automobile crane after each technological operation of its processing.
The impact of technological operations on the amount of deviation from roundness and the prevailing harmonics, which indicate the type of shape deviation, is determined. Moreover, the form of deviations from roundness is preserved after the first two operations. This indicates the presence of the phenomenon of technological heredity. Polygons for scattering deviations from roundness were built for deviations from roundness after each technological operation. It was established that the technological operation of semi-clean boring does not significantly change either the size or the shape of the deviation from the roundness of the inner cylindrical surface of the hydraulic cylinder sleeve.
The shape of the deviation from roundness will help to establish the defect of the machine tool and prevent the formation of detected deviations from the roundness of the processed surfaces. After performing rough and semi-finish boring, the first harmonic prevails in the distribution of amplitudes of harmonics of deviations from roundness. This indicates that during blade processing operations on the machine tool, radial beating of the spindle takes place.
The consequence of this is the formed eccentricity of the treated surface. After performing the finishing operation - final rolling, the third harmonic begins to prevail in the amplitude distribution of harmonics of deviations from roundness. It was established that the amount of deviations from roundness after the semi-clean boring operation does not significantly decrease with the shape of the deviation preserved, which indicates its ineffectiveness in terms of influence on the accuracy of the shape of the cross-sections when processing the inner cylindrical surface of the hydraulic cylinder sleeve.

Modern construction involves the laying of a large number of various engineering communications.It is often necessary to arrange crossings under highways, railway tracks and other ground structures, the destruction of which during open trench development is a very expensive procedure. Recently, the technology of trenchless laying of engineering communications has become widespread.The simplest and quite effective is currently the most common method of static puncture. This method of well formation is characterized by the occurrence of significant stresses in the soil around the working body, which can have a destructive effect on engineering objects located nearby, both in the soil and on the surface. There is an urgent need to study soil behavior during puncture, in particular, using mathematical modeling of the process.
The paper describes an approach to mathematical modeling of soil behavior in the process of puncture as a flow of a rigid-plastic medium. The movement of the medium is considered in Euler coordinates. The working body is modeled by a completely solid cone. The main assumptions are stated and substantiated. Pressure was considered instead of average stress. The density of the deforming medium was assumed to be constant.Under pressure was understood excess pressure, i.e. pressure caused by the action of the effort of the working body during a puncture.It was believed that soil resistance is determined mainly by the resistance of a relatively narrow layer adjacent to the working body.Instead of Cartesian coordinates, spherical coordinates were used in this case.As a result, all the dependencies characterizing the rigid-plastic flow are analytically deduced ‒ the fields of velocities, deformation velocities and stresses.
Justification of Individual Structural and Technological Parameters of the Potato Planting Machine

Published: February 2025

The purpose of the study is to substantiate the individual structural and technological parameters of the potato planting machine, which is used in the technology of growing potatoes and is intended for work in small farms in a unit with low-power energy sources.
The work proposes a new structural and technological scheme of the potato planting machine. The peculiarity of this construction is that it provides for strip milling along the axis of the formed row, and the formed soil shavings sprinkle potato seeds, which are placed on the formed and compacted planting place. First two pairs of wrappers form a small ridge with fresh soil and a final large ridge with soil from between the rows. During the execution of the study, the choice of the kinematic mode of operation of the milling drums in relation to the thickness of the ground shavings cut by the knives was substantiated, and the choice of the type of wrappers was made.
On the basis of the proposed construction of the potato planting machine, certain effects are observed in the comb method of planting potatoes. A high-quality seed place is formed due to a milled (loosened) strip of soil, along which the coulter moves with minimal resistance and with its lower part, which compacts the bottom, forms an additional small groove in which the seeds are placed. Due to this, the compacted bottom allows moisture to be drawn up from the lower layers of the soil, and its shape – an additional small groove prevents deviation of the tubers from the axis of the row. The next effect is strip milling, which consumes 2 times less energy compared to a separate milling operation during pre-sowing tillage. In addition, the potato seeds are covered with fresh and optimally lumpy soil from the milled strip. It was established that for the milling drum of the potato planter with a diameter of 0.5 m, the optimal rotation frequency is about 265 rpm, the forward speed of the unit is 3.3 km/h (0.92 m/s), and then the maximum chip thickness will be 15 mm. The formation of the comb during seed production involves two stages – the formation of first small and then the final large combs, where passive wedge wrappers are reasonably used.

The purpose of this paper is to improve road safety by analyzing the aerodynamic interaction between a truck and a motorcycle using computational fluid dynamics (CFD). The study focuses on evaluating the accuracy and reliability of different turbulence models commonly used in CFD simulations to determine their impact on motorcycle stability and control during overtaking maneuvers.
The research involved simulating the aerodynamic flow between a truck and a motorcycle using three different turbulence models: Spalart-Allmaras (SA), k-epsilon (k-ε), and k-omega (k-ω). Simplified CAD models of a European truck and a road motorcycle were created, and airflow structures were analyzed for each turbulence model. The aerodynamic drag acting on both the truck and motorcycle was evaluated, along with the effect of flow structure on motorcycle handling. The analysis included assessing the computational resources required for each model and comparing the predicted results with experimental data from previous studies.
The study concludes that different turbulence models produce varying flow structures and aerodynamic forces, with significant differences in their effect on motorcycle stability. The k-ω model was found to provide the most accurate predictions, although further experimental validation is required. The results highlight critical areas where drivers should maintain caution, particularly during overtaking maneuvers near large trucks.

За мастю – це тварини чорно-рябого та червоно-рябого забарвлення. Генетичний матеріал породи представлений у Каталозі бугаїв молочних і молочно-м’ясних порід для відтворення маточного поголів’я. Частка бугаїв-плідників голштинської породи займає 74,5%. Метою дослі дження було проаналізувати бугаїв-плідників червоно-рябої масті за комплексом показників, де основною була оцінкою за потомством та походженням. У роботу залучено інформація про 160 бугаїв носіїв RED фактору. Характеристика плідників поділена за результатами оцінки, а саме за типом і продуктивністю потомства (n=54 гол. або 34%), геномні (n=78 гол. або 49%), продуктивністю потомства (n=21 або 13%) та походженням ((n=7 гол. або 4%). Зазначені бугаї походять з 11 країн світу, з найбільшою кількістю США (30%), Нідерландів (22%), Німеччини (19%), Канади (19%), України (7%). Генеалогічна структура дослідженої вибірки належить до 16 споріднених формувань, де найчисельнішими – є лінії Чіфа 1427381 (74 гол.), Елевейшна 1491007 (46 гол.), Кавалера 1620273 (8 гол.). Понад 68% бугаїв-плідників отримані методом ембріотрансплантації, а 18% протестовані за геном бета-казеїну. У парувальну кампанію залучено 558,9 тис. доз. сперми, де 90% займають бугаї оцінені за потомством. Відмічено, що найвищу середню оцінку плідників за селекційним індексом (СІ+1256) та племінною цінністю за надоєм (+929 кг) мають тварини, які оцінені геномно. Значення цих показників у бугаїв оцінених за типом і продуктивністю потомства (86917 дочок у 24001 стаді) та оцінених за потомством (5683 дочки у 410 стадах) становлять СІ+694 і +650 кг та СІ+245 і +441 кг відповідно. Ймовірна племінна цінність за надоєм дочок бугаїв оцінених за походженням становить +801 кг. Подальші дослідження спрямовані на оцінку бугаїв різних генеалогічних формувань та генотипів за геном бета-казеїну.

Науковці бачать перспективним напрямком використання у практичній селекційній роботі заходи на основі маркер-асоційованої селекції. Це дозволяє проводити відбір тварин на основі оцінки їх генотипу та нівелювати вплив зовнішнього середовища. Особливо важливим фактором використання маркер-асоційованої селекції в молочному скотарстві – є значне прискорення ефекту селекції. Наукові дослідження з вивчення впливу гену РІТ-1 на показники молочної продуктивності корів-первісток проведені на базі двох племінних заводів з розведення української бурої молочної та української чорно-рябої молочної породи, що належать Державному Підприємству «Дослідне господарство Інституту сільського господарства Північного Сходу Національної академії аграрних наук України», розташованого в Сумському районі. Поліморфізм гену гіпофізарно-специфічного фактору транскрипції PIT-1 досліджували в генетичній лабораторії Інституту тваринництва за загально прийнятими методиками. Молочну продуктивність оцінювали шляхом щомісячних контрольних доїнь з відбором проб молока. Для відбору проб молока використовували лічильник – індикатор ІУ-1. Вміст складових молока визначали в лабораторії Інституту тваринництва НААН методом інфрачервоної фотометрії на обладнанні корпорації «Bentley Instruments» (США). Серед досліджених тварин обох порід не виявлено корів з генотипом АА. Більшість чорно-рябих первісток мали гетерозиготний генотип АВ, бурих – гомозиготний ВВ. Проведені дослідження засвідчили перевагу за надоєм корів української чорно-рябої молочної породи з генотипом АВ, а корів української бурої молочної породи з генотипом ВВ. Вищим вмістом жиру та білка в молоці у тварин обох досліджуваних порід відрізнялися первістки з гетерозиготним генотипом АВ. За середнім вмістом сухої речовини серед чорно-рябих первісток переважали тварини з гетерозиготним генотипом АВ, серед бурх – з гомозиготним генотипом ВВ. За середнім вмістом сухого знежиреного молочного залишку в молоці у тварин обох піддослідних порід переважали первістки з гомозиготним генотипом ВВ.

Innovative design of marketing ecosystems is a key factor in the success of modern business in the conditions of rapid market changes and technological progress. At the heart of this process is the creation of dynamic, adaptive and interconnected structures that are able to unite companies, consumers, partners and technologies into a single integrated environment. This approach involves not only the introduction of new tools and platforms, but also a rethinking of traditional models of interaction between market participants. Innovative marketing ecosystems help brands not only promote their products, but also create value through joint projects, audience engagement and the implementation of advanced technologies, such as artificial intelligence, big data analysis and process automation. The formation and use of marketing ecosystems allows you to simplify both the processes of transformation of technological structures and the interaction of different types of business models of enterprises. Special attention is paid to marketing ecosystems as one of the important innovations of Industry 5.0. The transition from Industry 4.0 to Industry 5.0 is accompanied by the creation of the necessary software and algorithmic base of quantum computing, the use of visualization technologies for management decisions, the development of neuromorphic models of enterprise architecture, and digital twins of business processes. The article considers the stages of innovative design of new marketing ecosystems, the implementation of which results in end-to-end integration of information resources of enterprises included in them, which is necessary for the consolidation and synchronization of structured and unstructured data on various business models of companies and the organization of predictive analytics mechanisms. As a result of the work, the method of scientific analysis of the literature on the research topic was used, the empirical experience of the authors of the article was used. The results of the study will be useful to managers of innovative companies and employees of marketing departments.

The article examines the criteria for recognizing and grouping intellectual capital for accounting purposes. It is substantiated that intellectual capital becomes a decisive factor in efficiency and long-term growth in a knowledge-based economy, where companies define their core competence as intangible assets. Scientific sources are studied and analyzed, which provide different approaches to identification, recognizing, measuring and assessing intellectual capital, and on their basis a number of problems are identified in reflecting the essence of this category for accounting purposes. For accounting purposes in the context of digitalization, the article, using a synergistic approach, proposes an interpretation of the concept of intellectual capital as a set of intangible resources, capabilities, reserves, potentials and knowledge, intellectual property objects owned or controlled by a business structure and which are able to constantly generate innovations; the main characteristics of intellectual capital are systematized; the important features of this capital are determined, taking into account the peculiarities of its structuring; a model of intellectual capital is formed. Taking into account the development of modern digital technologies, as well as security measures during war, it is proposed to separate information capital from organizational capital into a separate component. And from the general structure, artificial intelligence should also be isolated into a separate component. The criteria and characteristics that assets reflected in accounting as part of intellectual capital must meet are determined, in particular in particular: in form - intangible, and in nature - non-property and property, secondly, a reliable valuation, thirdly, the enterprise must benefit from the use of these resources in the form of profit and, fourthly, in general, the presence of intellectual assets should affect the increase in the market value of the business entity itself. The above characteristics will help to more clearly define not only the economic side of the concept of intellectual capital, but will also ensure its reflection in accounting and will contribute to determining their value.
