Authors: Locke Jennifer , Marinkovic Aleksandra , Hamdy Kareem , Balendra Vyshnavy , Sanyaolu Adekunle
Published: December 2023

The coronavirus disease 2019 (COVID-19) pandemic has put standard, routine childhood vaccinations at risk worldwide. The disruption in vaccine coverage has resulted in a negative impact on the health of children, with some races, ethnicities, age groups, areas of settlement, and parts of the world affected more than others. This literature review studied and examined the impact of COVID-19 on infant, child, and adolescent vaccinations. Retrospectively, the analysis showed a decline, delays, or interruptions in the coverage of vaccines during the pan-demic and a decline in some countries' pre-pandemic and post-pandemic eras. Necessary attempts and efforts should be made for these delayed and missed vaccinations, as failure to do so could put children's health at risk. Thus, priority should be directed at instituting catch-up programs to support vaccine uptake and decrease the probability of acquiring vaccine-preventable diseases.

The need for innovative wound dressings has arisen due to injuries from second intention healing and their management is associated with high costs. Modern dressings not only protect wounds but also promote proliferation of cells and tissue regeneration. Patient compliance is crucial, ensuring that the dressing removal does not harm the newly regenerated tissue. In this study, nano-chitosan polyvinyl alcohol- glycerol (NCH-PVA-GLY) transparent wound dressing was developed that expedites tissue repair and can be removed through an external stimulus without disrupting the regenerated tissue. This dressing efficiently absorbs excess wound exudates while maintaining proper hydration. Evaluation in male Wistar rats with wounds revealed that the dressing, when applied for 16 days, resulted in minimal inflammation and denser connective tissue compared to wounds devoid of dressings. The dressing exhibited enhanced re-epithelization and angiogenesis, facilitating effective wound closure. The exposure of the resultant dressing, to the incised wound facilitated complete wound closure in 16 days, suggesting the effectiveness of the dressings to cure superficial wound.

Published: December 2023

The main objective of this article is to analyze the transmission of monetary policy in the WAEMU zone via the bank credit channel, using monthly data from January 1999 to December 2021. Methodologically, we apply a TVP-VAR model that allows coefficients to vary over time to reflect potential changes in time series dynamics. First, we find that the bank credit channel remains relatively weak in the union. Secondly, monetary policy shocks have evolved over time. Thirdly, the tertiary sector is relatively more responsive to monetary policy shocks than the primary and secondary sectors.
Some Fixed Point Results of (α,β,φ,δ) Contractions in Extended Cone b-Metric Spaces
Authors: SELKO Zamir , SILA Eriola
Published: December 2023

This paper investigates the existence and uniqueness of fixed points for a class of generalized contractive mappings defined on extended cone metric spaces. Subsequently, we define and explore (α, β, φ, δ)-contractions, a generalization of traditional contractions that allows for a more nuanced understanding of the contraction behavior in extended cone metric spaces. The extended metric space was defined for the first time in 2017, by Kamran et al. (2017). They replaced the constant in the triangle inequality of the metric with a two-variable function and explored various fixed point theorems. In 2022, Das and Bag[4] introduced extended cone metric spaces by incorporating a three-variable map into the third condition of the cone metric. Afterwards, Selko and Sila introduced the concept of extended quasi cone b-metric spaces and demonstrated the Banach contraction within this framework. In 2018, Alqahtani. (2018) and colleagues established several fixed point results for a pair of orbital cyclic functions in an extended metric space. In this paper we prove some fixed point theorems for -orbital-cyclic functions in extended cone metric spaces by using the continuous map φ and a nonnegative constant δ.

Authors: LATIF Raja Mohammad
Published: December 2023

Soft set theory is a newly emerging tool to deal with uncertain problems and has been studied by researchers in theory and practice. The concept of soft topological space is a very recently developed area having many research scopes. Soft sets have been studied in proximity spaces, multicriteria decision-making problems, medical problems, mobile cloud computing networks, defense learning system, approximate reasoning etc. In 2020 Punitha Tharani and H. Sujitha introduced a new class of soft generalized star β-closed (Sft*β-closed) sets and Sft*β-open sets in soft topological spaces. They investigated some basic properties of Sft* β-closed sets and Sft*β-open sets. They also studied the relationship between this type of closed sets and other existing closed sets in soft topological spaces. The aim of this paper is to introduce some soft separation axioms called Sftg*β-R0 space, Sftg* β-R1 space, Sftg*β-T0 space, Sftg*β-T1 space, Sftg*β-T2 space, Sftg* β-regular space and Sftg*β-normal space in soft topological spaces. We investigate several properties and characterizations of this spaces in soft topological spaces.

Published: December 2023

This research, conductive polymer supported modified electrode system which was prepared for usage in direct methanol fuel cells. To test the behavior of these electrode system for methanol oxidation, cyclic voltammetry (CV), chronoamperometry (CHR) and electrochemical impedance spectroscopy (EIS) methods were used as electrochemical methods. As the working electrode, pencil graphite electrode (PGE) was preferred because of its porous structure, good ion conductivity, practicality in application and ease of preparation and obtaining. Thiophene derivative 4,4')-2,2'-(diazen-1,2 diylbis(4,1 phenylene))bis(4 (thiophene-2-ylmethylene) oxazol-5(4H)-one), (DiAzBiPhBiTyOx) monomer was prepared and electrochemically polymerized by CV method in 0.01M TBAP and 0.05 HClO4 containing ACN solution on the surfaces of PGE. The spectroscopic characterization of the synthesized monomer was performed by NMR spectroscopy. Optimum polymerization conditions of monomer was determined according to scanning rate, potential range and acid density. The obtained modified electrode system (PGE/PDiAzBiPhBiTyOx) was doped with chloroplatinic acid hexahydrat-Pt2Cl6.6H2O (Pt) at different densities and the optimum catalyst density was determined as 3.25mM (PGE/3.25mMPt@PDiAzBiPhBiTyOx). The methanol oxidation performances of conductive polymer film, platinum and conductive polymer supported platinum catalyst systems were investigated separately. While the methanol oxidation responses of the conductive polymer film and platinum are almost similar, the methanol oxidation response of the platinum doped conductive polymer film catalyst system is higher. The modified electrode characterization was performed by CV, CHR and EIS methods. Furtheremore obtained modified electrode systems were characterized by FESEM/EDS, XRD to confirm the structures and morphologies. Also, the theoretical values such as electrochemical surface area (ECSA) and specific capacitance (Cs) were calculated in aqueous acidic solution with and without methanol. Cs values of the PGE/3.25mMPt@PDiAzBiPhBiTyOx electrode in aqueous acidic solution with and without methanol were 3.861 and 3x10-4Fg-1 respectively. Also, the electrochemical surface area values of the same electrode in aqueous acidic solution with and without methanol were 196.437 and 21.150m2g-1 respectively.
Curvature Analysis in a Bi-layered Non-linear Elastic Bar under Uniform Heating
Authors: RIZOV Victor
Published: December 2023

The present theoretical paper is concerned with analysis of the curvature in a bi-layered bar of rectangular cross-section. The bar is subjected to uniform heating. The two layers of the bar have different thickness and material properties. Besides, the layers exhibit non-linear elastic mechanical behaviour that is treated by applying a power-law stress-strain constitutive relationship. The bi-layered bar curvature is studied analytically. For this purpose, the mechanical response of the bar to uniform heating is investigated. The strains in the two layers due to heating are analyzed. An equation is compiled by using the fact that the prolongations of the bar layers are equal. Two equations are worked out by considering the equilibrium of the layers. The analysis of the curvature presented in this paper is checked-up by comparing with a known solution for the curvature in a bi-layered linear-elastic bar under uniform heating. The uniform heating induced curvature in a bi-layered bar whose layers are continuously inhomogeneous in longitudinal direction is also studied.
G**β-Continuous and G**β-Irresolute Mappings in Topological Spaces
Authors: LATIF Raja Mohammad
Published: December 2023

Topology being somehow very recent in nature but has got tremendous applications over almost all other fields. Theoretical or fundamental topology is a bit dry but the application part is what drives crazy once we get used. Topology has applications in various fields of Science and Technology, like applications to Biology, Robotics, GIS, Engineering, Computer Sciences. Topology though being a part of mathematics but it has influenced the whole world with so strong effects and incredible applications. The concept of continuity is fundamental in large parts of contemporary mathematics. In the nineteenth century, precise definitions of continuity were formulated for functions of a real or complex variable, enabling mathematicians to produce rigorous proofs of fundamental theorems of real and complex analysis, such as the Intermediate Value Theorem, Taylor’s Theorem, the Fundamental Theorem of Calculus, and Cauchy’s Theorem. In the early years of the Twentieth Century, the concept of continuity was generalized so as to be applicable to functions between metric spaces, and subsequently to functions between topological spaces. Topology is an area of mathematics concerned with the properties of space that are preserved under continuous deformations including stretching and bending but not tearing. In 2023, Dr. T. Delcia and M. S, Thillai introduced a new type of closed sets called g**β-closed sets and investigated their basic properties including their relationship with already existing concepts in Topological Spaces. In this paper, we introduce g**β-continuous function, g**β-irresolute function, g**β-open function, g**β-closed function, pre-g**β-open function, and pre-g**β-closed function, and investigate properties and characterizations of these new types of mappings in topological spaces.

Authors: CELIK Serdar , ALPASLAN Beste
Published: December 2023

Student-Company Assignment is defined as a multi-criteria problem involving the allocation of students to companies according to various criteria. Universities offering workplace experience courses in their undergraduate programs send their students to companies. During this assignment process, allocating suitable students to suitable companies can be a challenging task, as company demands are limited, and certain companies are more preference after by many students. This study proposes a simulation approach to solve the problem. In the first stage of the study, various criteria for students and companies were identified. These criteria include the total number of students, the total number of companies, student preferences, company demands for students, language skills of students, academic grade point averages of students, subject-specific skills of students, language skills demand of companies, and subject-specific skills demand of companies. In the second stage of the study, student-company matching is performed considering these criteria. The SIMIO program was used to model and simulate this process. The contribution of this study to the literature can be summarized as a simulation approach to the student-company assignment problem. The proposed approach was applied to a university offering workplace experience and the results showed an improvement in terms of performance parameters compared to the existing situation.

Published: December 2023

Receiving the power emitted from the base station by smart phones and providing effective signaling is seen as a very critical problem. In order to eliminate this situation, some antenna technologies have been developed and started to be used in smart devices. The smart phones, which were developed by adhering to the DRx (Diversity Receive) design scheme, best perceived the signals emitted from the base station, thus increasing the Rx performance of the developed products. Typical integrated (total) surface metrics include Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS). TIS and TRP metrics have become increasingly important for carriers, because a TRP measurements used to verify your transmitter or transmitter antenna design. A TIS measurement used to verify how your receiver or receiver antenna design performs. In this study, we aimed to determine the Rx performance of the DRx scheme used in smartphones by using 3D radiation test setup (TIS - Total Isotropic Sensitivity).
Reduction of Shipping Greenhouse Emission by Alternative Fuels Used
Authors: DENEV Yordan
Published: December 2023

The article examines, assesses, and analyses various types of fuels used in shipping. between the ports of Varna and Rotterdam. In order to determine the fuel that generates the least amount of carbon dioxide and is cost-effective, various types of traditional marine fuels and those that are yet to be introduced into operation have been considered. The advantages and disadvantages of bunkering, transporting, and storing various types of alternative marine fuels have been defined. The analysis shows that the lowest carbon dioxide emissions are generated when using alternative biofuels such as methanol and methane. Furthermore, if HVO fuel, which has not yet gained widespread use in shipping, is employed, emissions will be reduced by approximately 90%. From an economic perspective, methane and methanol have the lowest cost per ton of fuel compared to HVO, which is about four times higher in comparison to methane and methanol. Considering the IMO regulations for reducing harmful emissions into the atmosphere, HVO appears to be the future fuel that will normalize its prices.
Indeterminate Continuously Inhomogeneous Beam under End Rotation: A Longitudinal Fracture Study
Authors: RIZOV Victor
Published: December 2023

The present paper describes a theoretical analysis of the effect of the end rotation of a statically indeterminate beam structure on the behaviour of a longitudinal crack. The beam is made of a material that is continuously inhomogeneous along the beam thickness. Besides, the material has non-linear elastic behaviour. The left end of the beam is supported with an axial double rod, while the right end is rigidly fixed. There is no external mechanical loading on the beam. Thus, the only influence on the beam is the rotation of the beam left end. Equations for determination the curvatures and the coordinates of the neutral axes are worked out and solved together with equations for resolving the static indeterminacy. The response of the longitudinal crack to the rotation of the beam left end is studied by deriving the strain energy release rate. For this purpose the balance of the energy in the beam is analyzed. The strain energy release rate is verified by applying the integral, J. A parametric analysis is performed to evaluate the influence of the beam end rotation and other factors on the longitudinal fracture.

Isotopic studies have been conducted on skeletal remains of ancient populations from Kythnos, an island of the Cyclades in Greece, for the purpose of dietary reconstruction; mostly through carbon and nitrogen isotopic signals of bone collagen, and apatite signatures (oxygen and carbon) as dietary and palaeoenvironmental tools. The basic aims of the present study are to reconstruct the diet of this population and to detect possible differentiations between the adult and the childhood/juvenile diet. The results of this study revealed that residents of Kythnos probably consumed C3 and C4 products as their primary protein source. In addition, the collagen results along with the collagen-apatite spacing possibly indicated a detectable consumption of freshwater sources. The isotopic analyses have been conducted at the Stable Isotope and Radiocarbon Unit of INN, NCSR “Demokritos”.

Authors: Irwanto Yahya , Wiyono Teguh , Wardani Kusuma
Published: December 2023

Introduction: Endometriosis is an inflammatory disease influenced by estrogen characterized by ectopic growth of the endometrial stroma and glands. Matrix metalloproteinase (MMP) is a proteolytic enzyme that has an important role in the remodeling of the extracellular matrix in normal tissues but also contributes to pathologies such as tumor invasion. The therapy has many drawbacks, including being expensive and in need of herbal therapy as an alternative. Phaleria macrocarpa is a native plant of Indonesia that contains flavonoids. This study aimed to evaluate the effect of Phaleria macrocarpa flavonoid isolate on the development of apoptosis, proliferation, and angiogenesis in mice model endometriosis.
Material and Methods: This research is a true experimental study with a Randomized Post-Test Only with a Control Group in the laboratory. Samples are divided into six groups, a control group and an intervention group, administered with flavonoid extract from Phaleria macrocarpa. Data analysis was carried out by using the Independent T-Test with SPSS for Windows 19.0 software.
Results: Each control and intervention group consisted of 6 mice. The normality test for each variable shows p> 0.05. Administration of flavonoid in each group shows a significant decrease in MMP-1 (20.4 ± 7.74 vs 65.68 ± 10.97, p=0.000), MMP-3 (53.34 ± 9.66 vs67.47 ± 10.05, p=0.000), and MMP-7 expression (40.52 ± 5.43 vs 54.13 ± 4.08, p=0.000).

The article addresses the issues related to the essential interpretation of the term "investment potential," its assessment in the current realities of Ukraine, and understanding of its role in crisis management of the national economy in modern conditions. The aim of the article is to identify investment potential as an economic category in the context of crisis management of the country's economy and determine its current state in Ukraine. An analysis of theoretical approaches to defining the concept of investment potential has been conducted, and they have been categorized into resource, probabilistic, market, capacity, structural, and performance directions. The definition of crisis management of the national economy is characterized, attempting to determine the role of the country's investment potential in such management. An analysis and assessment of the dynamics of foreign direct investments in Ukraine from 2002 to 2022 have been carried out, revealing that their total volume during the war year decreased by almost five times, negatively impacting the country's economy. The research emphasizes the necessity for Ukraine to enhance its investment potential to finance the needs of recovery and stabilization of the economic situation, both in the post-war period and the current stage, considering the challenges of digitization. The article argues that due to russia's military aggression and the prolonged war, Ukraine needs to explore new solutions to bring the national economy out of a crisis state and overcome the destructive consequences of warfare through digital solutions. This is achievable by boosting the country's investment potential, especially considering the insufficient domestic resources.

This article delves into the nuances of digital transformation within the realm of banking, prompted by the pervasive global digitization of economies. This phenomenon has profoundly shaped the trajectory of financial technologies, giving rise to innovative banking products. The primary objective of this study is to elucidate the essence of digital transformation and assess its efficacy in shaping the development of the banking sector.The digitization of banking involves the transformation of all associated processes and information. Consequently, the integration of digital technologies into the banking domain necessitates a comprehensive consideration of the needs of three key stakeholders: the consumer, the investor, and the bank itself. The authors conducted an analysis of the regulatory and legal landscape accompanying the digital transformation of the banking sector. The study concludes that the contemporary legal framework governing the use of digital technologies in banking is aligning with current global trends.The digital transformation of the banking industry is observed to manifest in several dimensions, encompassing remote and Internet banking, electronic payments, FinTech and innovation, blockchain and cryptocurrencies, cyber security systems, electronic identification and document circulation, as well as interoperability.The domestic banking system has exhibited noteworthy progress in digitalization in recent times. However, external factors, notably the incursion into Ukraine, have introduced certain adjustments. These include the outflow of intellectual human capital abroad, diminished financial literacy due to population migration, and the closure of bank outlets, particularly affecting territorial communities, especially rural areas, resulting in a loss of connectivity with banks.In light of these observations, it is asserted that future digital transformational endeavours in the banking sector should prioritize enhancing the financial literacy of consumers of banking services. Additionally, there is a need to fortify regulatory frameworks governing the cryptocurrency market in Ukraine and establish unified standards for the regulation and supervision of banks and FinTech companies providing digital financial services.

BUILDING A MODEL OF THE ANTAGONISTIC GAME OF CHOOSING THE STRATEGY OF FOREIGN ECONOMIC ACTIVITY IN THE CONDITIONS OF DIGITALIZATION
Authors: Kulish Damir
Published: December 2023

The purpose of the study is to build a model of the antagonistic game of choosing the strategy of the FEA in the conditions of digitalization. To do this, approaches to the use of Game Theory will be explored. The economic and mathematical apparatus and its application for the strategy of foreign economic activity are considered.This study allows us to determine whether Game Theory is a suitable analytical tool for foreign economic activity-oriented decision-making. In this context, through strategic interdependence games, FEA is associated with making decisions to determine whether to collaborate or compete, innovate or emulate in order to create innovative advantages in the company.It has been found that sometimes our economic decisions are influenced by the decisions of third parties; To understand how these decisions are made and which is the best among several alternatives, game theory arises. The study of game theory in economics will define a game as an abstraction of a specific economic situation. One or more solutions will be suggested, and the author will try to demonstrate which strategies correspond to the equilibrium in the presented game. Game theory cases are often represented graphically using matrices to better understand the reasoning of the participants.Companies use game theory not only to set prices but also to determine when and in which market to conduct FEA and predict competitive decisions. Therefore, the theory of games was applied to foreign exchange for different markets. In order to use this theory, it is necessary to have information about other players, their advantages, and limitations. It consists in achieving a balance of benefits for all. When all players have made a decision and if changing it makes them feel worse, a Nash equilibrium is said to be reached.

Published: December 2023

Budget Violations are a Significant Component of the Financial-Legal System in Ukraine, Regulating the Budgetary Process and Financial Relations among Its Participants. The article structures important aspects of budgetary violations, their legal responsibilities, and sanctions provided for by the relevant legislation. The Ukrainian system of responsibility in the field of budgetary legal relations encompasses a wide range of subjects and sanctions used to ensure compliance with financial norms and rules. This system is regulated by the current legislation, including the Budget Code of Ukraine, the Code of Ukraine on Administrative Offenses, and the Criminal Code of Ukraine. The definition of budget violations is a key aspect of analyzing this topic. A budget violation is the failure of a participant in the budget process to comply with the established procedure regulating the compilation, review, approval, amendment, and execution of the budget or the report on its execution. Participants in these violations include budget managers, recipients of budget funds, and local self-government bodies. Responsibility for such violations covers civil, disciplinary, administrative, and even criminal liability. For violations in the field of budgetary relations, the legislation provides a specific list of influence measures but also allows for the establishment of other sanctions through subordinate acts. Violations such as missing budget statements, improper budget fund allocation, and other forms of non-compliance can trigger the imposition of financial sanctions. An important characteristic is the specificity of budgetary relations, primarily having an imperative character and thereby constructing the structure of administrative responsibility in this area using formal elements of administrative-criminal acts. A comprehensive analysis and regulation of budget violations are essential elements of the stability and development of the state, ensuring compliance with financial norms and the accountability of budget process participants.
