Double Eclipse, Feast of the Annunciation and Mazepa’s Niece «Marcianna»
Authors: Yaremenko Maksym
Published: December 2024

The purpose of this publication is to introduce unknown information from the sermon of 1699 of the Kyiv pricher Stefan Yavorskyi, which concerns Ivan Mazepa’s niece Marianna Vitoslavska. Thanks to Yavorskyi’s mentions, we can establish the date and circumstances of Marianna’s taking the veil, and therefore revise the assumptions about the fate of Vitoslavska that proposed in historiography. The publication of the fragment of the sermon is preceded by a short introduction, designed to explain the context of the mention of Vitoslavska, as well as to recall the researchers’ assumptions regarding her biography.
Kyiv Academy in Travelogues of the Second Half of the 18th through Mid-19th Centuries
Authors: Dysa Kateryna
Published: December 2024

During the second half of the 18th century, Kyiv gradually started attracting an increasingly bigger number of travellers, both from the Russian imperial centre and Western countries. In some cases, Kyiv could be the final destination of travel, but in most cases, it was only one of the stops on a journey toward the South, in particular to Crimea. Given the widespread interest of learned travellers in issues of the Enlightenment and education, Kyiv Academy could stir curiosity and arouse a desire to visit this institution. That said, motives of interest among Russian and Western travellers could vary; the former were attracted by Kyiv Academy because of its input into the development of education and sciences in Russia itself. Some travellers expressed admiration toward the educational institution and emphasised its role in the education of learned members of the high clergy and bureaucracy. They also stressed the fact of a relatively long history of the Academy that had to prove the long tradition of education and science in the Russian Empire. However, Western travellers visited the Academy because of their general interest in the state of education in the Russian Empire. With time these tendencies changed. In this paper, we study mentions of the Kyiv Academy in travelogues; in particular, we are interested in the issue of the changing character of these mentions during a long period from the 1760s to the mid-19th century, both in the framework of the history of travel literature and from the point of view of imperial control of knowledge.

Published: December 2024

Self-efficacy is important for maintaining a person’s belief in their capacity to perform desired behaviours and achieve desired goals; without self-efficacy, in the context of academic writing, one may doubt their ability to achieve writing goals. Previous research showed that the Writing Meeting Framework (WMF) can enable desired changes in writing behaviours but did not consider the role of self-efficacy in this behaviour change. This UK-based study aimed to determine if the WMF could improve writing self-efficacy for postgraduate researchers (PGRs) and early career researchers (ECRs). Participants completed a baseline questionnaire to reflect on their writing experiences and then were randomly matched into 35 pairs. Each pair met online four times over eight weeks using the WMF and then completed a post-questionnaire, reflecting on their experiences. Analysis showed significant improvements in self-efficacy using the WMF: participants improved their ability to set realistic and achievable writing goals and increased their confidence in completing writing goals regularly. This study shows the WMF can develop PGRs’ and ECRs’ academic writing self-efficacy and suggests the WMF can develop writing attributes required to produce academic writing regularly and achieve individual writing goals. The WMF offers a mechanism for developing this important component of effective writing behaviour.

Authors: Araújo Sônia Maria da Silva , Hernández Oscar Andrés Piñera , Fagundo Dainerys Naranjo
Published: December 2024

O artigo trata da concepção de educação popular em José Martí, de Cuba, e Paulo Freire, do Brasil. Considerados duas referências no campo da educação, José Martí, que viveu de 1853 a 1895, e Paulo Freire, que, por sua vez, viveu de 1921 a 1997, têm produção consistente na área da Educação, em particular no campo da educação popular. Mas, que relações há entre a concepção de educação popular de José Martí e de Paulo Freire? Metodologicamente, é um estudo bibliográfico, voltado para a análise de eixos teóricos que permeiam a ideia de educação popular nos autores. Os resultados demonstram que a concepção de Educação Popular, em José Martí e Paulo Freire, é marcada por um profundo humanismo, perspectivado pelo senso de justiça e luta por liberdade. A pedagogia que dá sustentação à ideia de educação em ambos os autores é a vida. A educação é defendida, por eles, como com um instrumento de luta pelo direito à existência digna.

Preparing Russians for Retirement from the Perspective of the Active Longevity Concept (Based on the Yaroslavl Region)
Authors: Kiselev Igor , Zagrebin Vladimir , Ovchinnikova Natalia
Published: December 2024

The article describes attitudes towards the choice of labour, financial, and health-preserving trajectories of Russians in preparation for retirement based on the results of the author's sociological study conducted using the method of personal interviews (n = 650). It is shown that in the context of demographic aging in Russia, there is a gradual shift away from understanding aging as a mutual alienation of an elderly person and society, and the elderly - exclusively as objects of care, towards considering the elderly as active participants in public life, in relation to whom the policy of active longevity is implemented. It involves a system of measures to promote employment of the elderly, maintain material well-being, improve health and quality of life, and learning throughout life. However, the index of active longevity in Russia remains low.
The assertion is substantiated that the system of measures in line with the concept of active longevity policy has a proactive nature, that is, it is aimed at future generations of elderly people, rather than the current ones, and involves preparation for the period of aging, marked by retirement. Based on the data of the conducted sociological study, it is shown that the labour, financial and health-preserving trajectories of respondents who have not reached retirement age, regarding the preparation for the retirement in some ways are in line with the principles of active longevity, and in some ways, contradict them. At the same time, the main differences are observed between respondents under 46 years of age and pre-retirees.
The respondents' orientation towards long-term employment, readiness for lifelong professional training, mastering non-traditional forms of employment (for example, readiness to work on Internet platforms), awareness of responsibility for ensuring their economic well-being in old age and the use of various strategies for this (professional-labour, savings, investment), the attitude towards giving up bad habits and maintaining physical activity (sports, physical education) create the basis for living out their aging by future pensioners in accordance with the principles of active longevity.
There are also barriers that hinder the transformation of the aging model in the direction of following the principles of active longevity: the influence of objective factors of economic instability, a low level of financial literacy of the population, the lack of special financial planning skills in preparation for retirement, the lack of a culture of health care.
Citizens' Perception of Historical Justice in the Modern Socio-Cultural and Political Contexts
Authors: Volkov Yuriy
Published: December 2024

Today, Russian society is faced with the need to rethink the reality in which it has found itself, including in connection with the reunification with new territories in the south of the country, the transformation of the entire system of national and international security, the construction of new meanings and interpretations of social and political processes. Changes in the sphere of socio-political, international and economic relations occur against the background of the processes of formation of the mobilisation type of state development, requiring the development of new value models and adaptation strategies for the behaviour of the population. In such conditions, historical justice, determining the logic of interpretation of events and processes occurring in Russian society, acts as a "demarcation" line in the mass consciousness and behaviour of the country's population. Determining the specifics of citizens' perception of historical justice can serve as the basis for coordinating public interests and creating an ideological coordinate system necessary for society in conditions of crisis and value contradictions.
The purpose of the study is to consider historical justice as a factor in the civil integration of the Russian post-Soviet multicultural society in the context of socio-cultural challenges. The methodological basis of the study is built on the theories of natural and historical justice. The constructivist and riskological approaches were also used in this study.
Within the framework of this publication, the following fundamental blocks are considered: historical justice as a direction of the state's social policy; ethnocultural interaction in the multicultural space of the Russian post-Soviet society; the role of historical justice in the integration of the Russian post-Soviet multicultural society in the context of socio-cultural challenges.
As a result of the analysis of the presented blocks, the author comes to the conclusion about the need to implement a special state policy in modern Russian society aimed at constructing and strengthening the civil integration of the Russian multicultural society on the basis of integrating narratives. Such narratives should be based on the concept of continuity of national history, and they should unfold only on the principles of the culture of socio-political and scientific dialogue.
The prospects of the research are connected with further study of existing factors of civil integration of Russian society, aimed at cultivating the values of humanistic worldview of Russian post-Soviet multicultural society in the context of new socio-cultural challenges.

Innovative ways to strengthen walls
Authors: Veselov Vitaliy
Published: December 2024

Purpose: to analyze the possible use of composite materials to strengthen stone structures of walls and pillars, to investigate the possible reduction of material consumption and labor intensity of innovative reinforcement options while increasing reliability and durability. Methods: analysis of the advantages of hybrid structures used for their design of materials, calculation of design options using existing engineering techniques and using calculation programs. Results: traditional structural solutions for strengthening stone structures do not always have sufficient reliability and durability. The disadvantages of the known solutions are the increased material consumption of the reinforcement structure due to excessive consumption of concrete, steel, excessive increase in cross-section, as well as insufficient operational reliability of the reinforcement structure associated with corrosion wear of steel elements. A number of effective hybrid structures using composite materials have been developed at the Department of „Building Structures, Buildings and Structures“ of PSUPS. The construction of the reinforcement of the wall, protected by a patent for the invention, is proposed. The reinforcement design includes reinforcement elements installed and fixed in the reinforced structure with the ability to work together with it. The reinforcement elements are made in the form of rows of composite rods mounted on a polymer solution in the transverse seams of the brickwork and forming reinforced layers along the height of the reinforced structure. The reinforcement elements in the upper part of the reinforced structure are made of carbon fiber fabric glued to the surface of the brick wall along the entire contour. A constructive calculation of reinforcement options was performed, an analysis was made of reducing the weight of the structure, material consumption, labor intensity and other advantages of an innovative solution in comparison with traditional reinforcement structures of stone structures. Practical significance: the advantages of composite materials in strengthening stone structures are revealed. The innovative reinforcement design has a lower weight of 2,5–4 times, while reducing the cost by 10–30 % compared to traditional designs and increasing durability. The proposed design solution can be rationally applied when reinforcing brick walls and pillars with an overload of up to 60–80%, and reinforcement can also be used to strengthen sections of walls damaged by sedimentary cracks.

Model of hierarchical mobile radio network data flow management system
Authors: Salnyk Serhii
Published: December 2024

The article proposes a model of a hierarchical system of managing data flows of a mobile radio network, based on the interaction of intelligent agents and using neural inference. The essence of the development of this model is to describe the data flow management system in the form of a hierarchical distribution of the process of receiving and processing input data in the data flow management system. This model uses a multi-agent system to represent knowledge about the external environment of the system in the form of a mathematical model of an agent with different possible states. Next, the multi-agent system is presented in the form of a graph, using graph theory to describe the data flow management system and their interaction processes. Then the formation of a neural output with fuzzy sets occurs, as a result of which all received fuzzy input data will be reduced to a clear appearance. The next step involves the use of a neural network. At the last step, a simulation model is developed using a tool for its implementation. иThis will make it possible to simulate the control and switching system, digital data processing, taking into account the behavior caused by various external factors, taking into account the peculiarities of the use of the model in mobile radio networks. In general, the essence of creating an intelligent management system using a hierarchical decision-making support system is the possibility of interaction between elements of different types of networks using decision-making systems, by exchanging information when making management decisions. The developed model will make it possible to systematize the design process of the data flow management system in mobile radio networks, hierarchically distribute the process of receiving and processing input data, reduce the time of data processing and loading of the node and network resources used, using multi-agent systems, neural inference and modeling.

Published: December 2024

The interaction between metal nanoparticles and substrates under plasmonic resonance conditions plays a crucial role in various optical applications. In this study, we research the impact of substrate material on the optical response of silver nanoparticles under surface plasmon resonance conditions. Using theoretical modeling based on the quasi-static dipole approximation, we explore how the dielectric constant of the substrate affects the extinction cross-section spectra of silver nanoparticles as a function of nanoparticle size and distance from the substrate surface. The calculation results show significant shifts in the extinction peak and enhancements in the extinction cross-section values when considering different substrate materials, including cellulose, indium tin oxide and silver. It was found that substrates with higher dielectric constants induce larger shifts in the extinction peak towards longer wavelengths and lead to increased extinction cross-section values at the operating wavelength. Furthermore, it was found that the orientation of the external electric field relative to the substrate surface influences the magnitude of these shifts. The results of the study show that while changing the size of the nanoparticles has minimal effect on the position of the extinction peak, increasing nanoparticle size significantly enhances the maximum extinction cross-section values. Additionally, varying the distance between the nanoparticles and the substrate surface causes shifts in the extinction spectra, with larger shifts observed for substrates with higher dielectric constants. These findings provide valuable insights into the design and optimization of plasmonic structures for various optoelectronic applications. By understanding the nanoparticle-substrate interactions and their optical properties, our theoretical study aids in the prediction of optical responses and the development of tailored optical structures for enhanced productivity of their usage. Overall, this study highlights the importance of substrate material selection and nanoparticle-substrate interactions in engineering plasmonic systems for advanced optical applications, paving the way for the design of efficient and optimized optoelectronic devices and sensors.

Indonesia-Singapore Realignment Agreement 2022: Quo Vadis Indonesia’s Air Sovereignty, Defense and Security?
Authors: Putro Yaries Mahardika , Felix Alexander Kurniawan  , Britney Nathania Lielien Putrajaya  , Sherren Laurencia
Published: December 2024

In 2022, after a 76-year wait, Indonesia finally witnessed the fruition of the Agreement on the Realignment of the Jakarta Flight Information Region and the Singapore Flight Information Region. However, President Jokowi's statements created ambiguity, leading to widespread misconceptions that Indonesia's airspace sovereignty over the Riau Islands and Natuna was only established during his tenure through the FIR agreement in 2022. This research aims to evaluate the impact of the airspace adjustment agreement ratified in 2022 between Indonesia and Singapore on Indonesia's air sovereignty and explore potential legal remedies. The research methodology encompasses normative legal analysis, including statutory, conceptual, and historical approaches. From a sovereignty standpoint, the FIR agreement in 2022 has implications for violating Indonesia's airspace sovereignty. Past sovereignty violations resulting from the 1995 FIR agreement could resurface post-2022. Civil-military cooperation in air traffic management is needed to restore Indonesia's compromised airspace sovereignty fully. Moreover, the agreement's 25-year duration conflicts with Law Number 1 of 2009 on Aviation. To rectify this, a crucial legal step involves establishing a takeover agreement, rather than a mere realignment, of the FIR from Singapore, followed by ratification through legislation. The public can engage in a judicial review of Presidential Regulation No. 109 of 2022 at the Supreme Court. Additionally, it is imperative to advocate for creating an Airspace Management Bill to address these complex airspace sovereignty concerns.

Published: December 2024

The molecular genetics of plant cell wall synthesis is a critical area of research with significant implications for biofuel production. The plant cell wall, a complex network of biopolymers including cellulose, hemicellulose, pectin, and lignin, represents a substantial portion of plant biomass and is fundamental to plant structure and growth. Advances in functional genomics and molecular genetics have led to the identification of key genes and enzymes involved in the biosynthesis and remodeling of these polysaccharides. Notably, the biosynthesis pathways of matrix polysaccharides are well understood, providing a foundation for manipulating their structure in planta to enhance biomass properties. Genetic engineering approaches, including the modification of genes related to lignin biosynthesis, have shown promise in improving the efficiency of saccharification, a critical step in converting plant biomass to fermentable sugars for bioethanol production. Techniques such as transgenic approach, quantitative trait locus (QTL) mapping and association mapping are also employed to identify and manipulate genes associated with cell wall polymer synthesis, offering potential for marker-assisted breeding. Additionally, advanced analytical tools such as systems biology and synthetic biology approaches facilitate the detailed structural analysis of cell wall polymers, enabling targeted modifications to optimize cell wall properties for bioenergy applications. Collectively, these advancements position plant cell wall biosynthesis research at the forefront of developing sustainable biofuel production strategies for advancing the energy sector.

Solar eclipses present a valuable opportunity for controlled in-situ ionosphere studies. This work explores the response of the upper atmosphere’s F-layer during the total eclipse of April 8, 2024, which was primarily visible across North and South America. Employing a multi-instrument approach, we analyze the impact on the ionosphere’s Total Electron Content (TEC) and Very Low Frequency (VLF) signals over a three-day period encompassing the eclipse (April 7 to 9, 2024). Ground-based observations leverage data from ten strategically positioned International GNSS Service (IGS)/Global Positioning System (GPS) stations and four VLF stations situated along the eclipse path. We compute vertical TEC (VTEC) alongside temporal variations in VLF signal amplitude and phase to elucidate the ionosphere’s response. Notably, IGS station data reveal a decrease in VTEC during the partial and total solar eclipse phases, signifying a reduction in ionization. While VLF data also exhibit a general decrease, they display more prominent fluctuations. Space-based observations incorporate data from Swarm and COSMIC2 satellites as they traversed the eclipse path. Additionally, a spatiotemporal analysis utilizes data from the Global Ionospheric Map (GIM) database and the DLR’s (The German Aerospace Center’s) database. All space-based observations consistently demonstrate a significant depletion in VTEC during the eclipse. We further investigate the correlation between the percentage change in VTEC and the degree of solar obscuration, revealing a positive relationship. The consistent findings obtained from this comprehensive observational campaign bolster our understanding of the physical mechanisms governing ionospheric variability during solar eclipses. The observed depletion in VTEC align with the established principle that reduced solar radiation leads to decreased ionization within the ionosphere. Finally, geomagnetic data analysis confirms that external disturbances did not significantly influence our observations.

Background/Objectives: Gender differences in nutrition-related determinants of mild cognitive impairment (MCI) exist among the elderly. This study aimed to explore gender-specific influencing factors of MCI. Methods: A nested case-control study was conducted in 2020, involving 1086 elderly people aged 55 years and above from 4 sites in Zhejiang Province, China. Data on demographics, cognitive assessment, depression scale, daily food intake and physical examinations were collected. The assessment of plant-based diets pattern depended on an overall plant-based diet index (PDI), a healthful plant-based diet index (hPDI), and an unhealthful plant-based diet index (uPDI). Multivariate logistic regression models were employed to assess the determinants of MCI in females and males. Results: Among 571 females, 141 (24.7%) had MCI, and 126 (24.5%) had MCI among 514 male participants. In females, the multivariate analysis revealed that being unmarried/divorced/widowed (OR = 1.949, 95% CI: 1.102 - 3.445), having depression (OR = 6.061, 95% CI: 1.868 - 19.660), and having a uPDI score ≥ 55 (OR = 2.412, 95% CI: 1.498 - 3.885) were associated with a significantly elevated risk of MCI. Conversely, a cereal consumption of ≥ 300g (OR = 0.318, 95% CI: 0.193 - 0.526) was linked to a significantly reduced risk. In males, vegetable consumption ≥ 150g (OR = 0.391, 95% CI: 0.232 - 0.658), vegetable oil consumption ≥ 22g (OR = 0.502, 95% CI: 0.307 - 0.820), and cereal consumption ≥ 300g (OR = 0.438, 95% CI: 0.271 - 0.709) were associated with a lower MCI risk. Meanwhile, rural residence (OR = 1.904, 95% CI: 1.116 - 3.249) and advanced age, especially 75 years old and above (OR = 4.713, 95% CI: 2.437 - 9.117), were also risk factors in males. Notably, Restricted Cubic Spline (RCS) model showed that females with a uPDI score < 55 had a lower prevalence of MCI, while those with a score ≥ 55 faced a higher risk. Conclusions: This study indicates potential gender disparities in the risk factors for MCI. Future research should prospectively establish causal relationships. Additionally, precise intervention strategies are urgently needed.
Integrating Electromagnetic Interactions into the QMM Framework

Published: December 2024

We present a framework extending the Quantum Memory Matrix (QMM) principles, originally formulated to reconcile quantum mechanics and gravity, to the domain of electromagnetism. In this discretized space--time approach, Planck-scale quantum cells act as memory units that store information via local quantum imprints of field interactions. By introducing gauge-invariant imprint operators for the electromagnetic field, we maintain unitarity, locality, and the equivalence principle while encoding electromagnetic data directly into the fabric of space--time. This construction ensures that black hole evaporation, including for charged black holes, respects unitarity, with initially hidden quantum information emerging through subtle, non-thermal correlations in the emitted radiation. The QMM framework also imposes a natural ultraviolet cutoff, potentially modifying vacuum polarization and charge renormalization, and may imprint observable signatures in the cosmic microwave background or large-scale structures from primordial electromagnetic fields. Compared to other unification proposals, QMM does not rely on nonlocal processes or exotic geometries, favoring a local, covariant, and gauge-invariant mechanism. Although direct Planck-scale tests remain challenging, indirect observational strategies—ranging from gravitational wave analyses to laboratory analog experiments—could probe QMM-like phenomena and guide the development of a fully unified theory encompassing all fundamental interactions.

Published: December 2024

Emerging edge devices are transforming the Internet of Things (IoT) by enabling more responsive and efficient interactions between physical objects and digital networks. These devices support diverse applications, from health-monitoring wearables to environmental sensors, by moving data processing closer to the source. Traditional IoT systems relied heavily on centralized servers but advances in edge computing and Tiny Machine Learning (TinyML) now allow for on-device processing, enhancing battery efficiency and reducing latency. While this shift improves privacy, the distributed nature of edge devices introduces new security challenges, particularly regarding TinyML models, which are designed for low-power environments and may be vulnerable to tampering or unauthorized access. Since other IoT entities depend on the data generated by these models, ensuring trust in the devices is essential. To address this, we propose a lightweight dual attestation mechanism utilizing Entity Attestation Tokens (EATs) to validate the device and ML model integrity. This approach enhances security by enabling verified device-to-device communication, supports seamless integration with secure cloud services, and allows for flexible, authorized ML model updates, meeting modern IoT systems’ scalability and compliance needs.
