Authors: Natasha  , Suryono Ryan Randy
Published: January 2025

This study analyzes public sentiment towards the influence of the Korean wave in Indonesia using the Naive Bayes and Support Vector Machine (SVM) methods. The Korean wave, as a popular cultural phenomenon from South Korea, has had a significant influence on various aspects of Indonesian society. The dataset consists of 6,327 tweets obtained through a crawling process on social media X, with 80% data divided for training and 20% for testing. The pre-processing process includes cleaning, case folding, tokenizing, stopwords, and stemming. Data imbalance in sentiment distribution is overcome by the SMOTE technique. The test results show that the SVM model has the highest accuracy of 89%, outperforming the Naive Bayes model with an accuracy of 81%. Performance evaluation using precision, recall, and F1-score shows that SVM is more consistent in classifying positive and negative sentiments. Data visualization is done using bar charts and word clouds to illustrate the main patterns and themes in discussions related to the Korean wave in Indonesia. However, this study has limitations, such as data is only taken from one social media platform, so the results are less representative of public opinion as a whole. Nevertheless, this study provides new insights into how Indonesian society responds to popular culture phenomena online. These findings can also be utilized by policymakers to support the development of creative industries based on popular culture.

The practice of forming and strengthening the fiscal potential of local budgets in Ukraine
Authors: Demianyshyn Vasyl , Tkachyk Fedir , Sishchuk Mariia
Published: January 2025

Introduction. The formation of the revenue side of local budgets under martial law in Ukraine is one of the key tasks for effective local government in territorial communities. They must establish effective cooperation with state authorities, particularly the State Tax Service of Ukraine, international institutions, specialized (public) organizations dealing with budget and tax administration issues, and business entities – taxpayers – to build sufficient fiscal potential in local budgets and ensure the sustainable development of territorial communities. It is necessary to substantiate ways of forming local budget resources by effectively using fiscal instruments, considering the current economic conditions under which territorial communities in Ukraine function.
Research Objective. The purpose of this article is to monitor the theoretical and practical foundations of forming the fiscal potential of local budgets in Ukraine and to develop ways to optimize it to ensure the sustainable development of territorial communities in the current context.
Methodology. General scientific and special research methods were used in writing the article, including systematic analysis, functional analysis, structural methods, statistical methods, comparison, synthesis, observation, induction, deduction, and other methods of scientific inquiry.
Results. The theoretical and methodological principles of forming local budgets in Ukraine have been substantiated. An organizational framework for accumulating fiscal resources of territorial communities under decentralization in Ukraine has been developed. The analysis of state and local budget revenue by income categories showed a general upward trend in tax payments despite the challenges posed by martial law. It was found that the most fiscally effective algorithm is the collection and distribution of personal income tax across different levels of the budget system, confirmed by empirical calculations of the performance of the State Tax Service of Ukraine in meeting planned indicators. The study also revealed that, in practice, the functioning of territorial communities is mainly supported by revenues from local taxes and fees, particularly the single tax and land rent, while revenues from real estate taxes (other than land) have a lesser fiscal effect. There are certain fiscal losses in local budgets in frontline regions, requiring an adequate response from state and local authorities to stabilize the fiscal potential of these local budgets. Based on these trends, methods for increasing the fiscal potential of local budgets in Ukraine have been proposed, focusing on cooperation between local authorities and other fiscal entities, creating a favorable investment-innovative climate in the regions, using modern information systems and tax administration technologies, and following the key principles of budget resource formation applied in foreign countries.

Methods of financial management in local communities under the conditions of the russian-Ukrainian war
Authors: Pysmennyi Vitaliy , Rudan Vitaliy
Published: January 2025

Introduction. Decentralization in Ukraine was a key factor in the process of reforming public administration aimed at expanding the powers and increasing the financial resources of territorial communities. However, this process was met with numerous challenges, which were complicated by the full-scale russian invasion, which became a serious test for local governments. The russian-Ukrainian war increased the uneven distribution of financial resources, which contradicts the idea of balanced development of all territorial units. This requires bringing financial management methods into line with new realities, in particular to reduce socio-economic disparities.
Goal. The goal of the article is to analyze the practice of using methods of managing the finances of territorial communities, to identify their shortcomings and to substantiate the possibilities of adaptation to the conditions of the war and the period of post-war reconstruction.
Methods (methodology). The article uses general scientific methods of research, namely: dialectical method, methods of analysis and synthesis, statistical method, methods of comparison and generalization.
Results. The analysis of the practice of using methods of managing the finances of territorial communities in the conditions of the russian-Ukrainian war indicates the need to bring financial instruments into line with the rapidly changing environment. Adaptive models of financial forecasting and planning, including dynamic and scenario models, as well as the integration of big data processing technologies and artificial intelligence, are critical for increasing the accuracy of forecasts and flexibility in decision-making by local self-government bodies. Special attention should be paid to issues of financial regulation, which allows not only to ensure the basic needs of territorial communities, but also to support national security and defence through the redistribution of funds between budgets of different levels. Improving the effectiveness of financial control requires active interaction with the public, which is important to prevent abuses and optimize costs in the difficult conditions of war and post-war reconstruction.

Features of the reproduction of the material and technical base of agriculture
Authors: Lipskyi Yurii
Published: January 2025

Introduction. The systemic crisis has had a profound impact on agriculture and its material and technical base, whose deterioration has significantly affected the condition of the country's agricultural sector. Improving the efficiency of agricultural production is only possible by developing a highly advanced material and technical base and ensuring its renewal through modernization, technical re-equipment, and the creation of machinery systems for mechanization and automation in agriculture.
Method (Methodology). To achieve the objectives of this research, the following methods and approaches were employed: the monographic method – for a comprehensive study of the features of forming and efficiently utilizing elements of the material and technical base in agricultural production and identifying factors influencing its reproduction intensity; comparison – to analyze economic phenomena across different time periods to establish cause-and-effect relationships; graphical methods – to study connections, identify trends, and determine patterns in the effective use of agricultural equipment by enterprises; and the abstract-logical method—to develop rational organizational and economic conditions for reproducing the elements of the material and technical base in agricultural enterprises.
Results. It has been proven that, given the specifics of the reproduction of the material and technical base, it is necessary to develop and implement methods for regulating the reproduction process. The research establishes that the reproduction of the material and technical base in agriculture requires adequate attention from both the state and business entities where this process occurs. Determining how to regulate the reproduction of these elements is essential. The state and its institutions play a key role in shaping the conditions for reproduction, influenced by a complex of socio-economic relations that include economic, social, legal, and other factors. The state's policy on reproduction involves not only setting conditions but also regulating the economy.
Tourism and the russian-Ukrainian war: current issues and post-war recovery prospects
Authors: Khanenko Alla , Bobko Natalia
Published: January 2025

Introduction. The article is devoted to analyzing the impact of the full-scale Russian-Ukrainian war on Ukraine's tourism industry and the possibilities for its recovery in the post-war period. Tourism is a vital component of both the global and national economies, contributing to job creation, infrastructure development, and increasing local budget revenues through tax revenues. However, military actions have drastically worsened the situation in Ukraine's tourism sector, leading to the closure of businesses in this sector, a significant decrease in tourist flows, and a reduction in Ukraine's international attractiveness as a tourist destination.
Purpose of the article. The purpose of the article is to comprehensively study the impact of military actions on Ukraine's tourism industry, particularly through the lens of geopolitical and economic factors. The study also examines the prospects for post-war recovery of the industry and identifies the steps necessary to revive tourism activity and restore international tourist flows.
Research methods. To achieve the set goal, the study used methods of systemic and comparative analysis, which allowed for an assessment of the dynamics of changes in the tourism sector before and after the war began. The historical method was employed to analyze the experience of other countries that successfully restored their tourism industries after large-scale conflicts. The forecasting of industry development was conducted using the modeling of potential recovery scenarios.
Results. The analysis showed that Ukraine's tourism sector has suffered catastrophic losses due to military actions. This led to a sharp decline in tourist flows, the closure of hotels, restaurants, transport companies, and other tourism-related businesses. Despite this, the article outlines possible post-war recovery scenarios, which include government subsidies, infrastructure development, support for small and medium-sized businesses, and the use of international experience in tourism recovery after conflicts. Special attention is given to the role of tourism as a tool for the socio-economic recovery of the country, as well as the importance of domestic tourism during the rebuilding phase.
Conclusion. The article emphasizes that, for the successful recovery of Ukraine's tourism sector, strategic steps must be implemented. These include attracting international support, reorganizing tourism infrastructure, and developing new tourism products oriented toward both domestic and foreign consumers.
Fiscal policy of the state and its impact on the commodity structure of Ukrainian exports
Authors: Bublyk Myroslava
Published: January 2025

Introduction. The problem of the impact of fiscal policy on the commodity structure of Ukraine's exports lies in the need to stimulate the export of products with high added value, which would contribute to the diversification of the economy and increase its competitiveness. The relevance of this problem is due to Ukraine's dependence on the export of raw materials, which makes the economy vulnerable to external shocks and reduces its stability in global economic conditions.
Purpose. To investigate the directions of improving the state's fiscal policy to improve the commodity structure of Ukraine's exports
Method (methodology). The methods of analysis, synthesis, comparison, justification, abstract-logical, graphic and statistical were used in the work.
Results. Among the modern trends in the study of the impact of fiscal policy on the structure of exports, innovative instruments of tax and customs stimulation were highlighted, their effectiveness in supporting the export of products with high added value, the importance of digitalization and integration of policies with international standards were emphasized. During the analysis of the commodity structure of Ukraine's exports, it was established that its structure is dominated by raw materials, in particular, the agricultural sector, metallurgy and mineral raw materials, which indicates a low level of diversification and insufficient presence of products with high added value. Taking into account the peculiarities of the commodity structure of exports and current trends in the development of fiscal policy in the world, a system of measures that should be implemented in Ukraine in the field of fiscal policy to stimulate the export of products with high added value was recommended. The recommended measures include improving tax legislation by introducing benefits for export-oriented enterprises, developing innovative activities and supporting sectors with high added value. It is also proposed to create an effective export support infrastructure, harmonize fiscal mechanisms with international standards and stimulate the integration of Ukrainian producers into global value chains.

Świadomość dzieci o osobach z niepełnosprawnościami i ich barierach
Authors: Szadura Kornelia , Gleń Piotr
Published: January 2025

W Polsce idea projektowania uniwersalnego, choć zyskała popularność w latach 90. XX wieku, była już wcześniej związana z prawami człowieka i urbanistyką. Obecnie stanowi standard i wymóg prawny w wielu aspektach projektowych. Tematyka ta dotyka również szeroko pojętego zagadnienia Zrównoważonego Rozwoju (SDG 11), które promują tworzenie miast bez barier i inkluzywnych przestrzeni dla osób z niepełnosprawnościami. Projektowanie uniwersalne, oparte na różnorodności i potrzebach wszystkich użytkowników, ma na celu eliminację przeszkód technicznych, społecznych i psychologicznych, które ograniczają samodzielność i uczestnictwo w życiu społecznym. Istotnym wyzwaniem pozostaje podnoszenie świadomości społecznej oraz uczenie empatii, co prowadzi do naturalnego projektowania przestrzeni dostępnych dla każdego. Pomocne mogą stać się warsztaty dla dzieci, które wprowadzą świadomość o osobach niepełnosprawnych i ich barierach, jak i również pokażą dotychczasową świadomość na podany temat. Wyniki ukazują, że dzieci miały styczność z osobami niepełnosprawnymi poruszającymi się na wózku i potrafią wskazać bariery architektoniczne dla tych osób, lecz mniejsza jest świadomość o niepełnosprawności wzrokowej.

This work presents a comprehensive study on the sensitivity optimization of electrical impedance flow cytometry devices for identifying analytes suspended in a flowing liquid. The optimization is achieved by investigating the influence of various parameters, including applied frequency, electrode geometry dimensions, bacterial properties, and buffer characteristics. The study utilizes COMSOL Multiphysics simulation to analyze the impedance variation based on differential Maxwell’s equations solved using finite element methods. The frequency optimization reveals that the sensitivity peak is around 12.6 kHz when considering imaginary impedance due to medium conductivity. Geometry optimization involves electrode dimensions with a length of 30 µm and a gap of 15 μm, as well as a channel width and height of 20 μm. Furthermore, the paper explores the effect of buffer conductivity, showing that it plays a significant role in defining total impedance with or without cells/particles. Higher buffer conductivity leads to dominant changes in real impedance, while lower conductivity affects imaginary impedance more prominently. The study also investigates the impact of variations in bacterial parameters, such as cell membrane permittivity and cytoplasm conductivity. These parameters influence total impedance, with cell radius showing a notable effect on sensitivity. By optimizing these parameters, the sensitivity and performance of impedance-based flow cytometry devices can be enhanced, making them more effective for bacterial analysis and characterization in various applications.

We established atomic layer deposition (ALD) process of InZnOx (IZO) and fabricate the ALD IZO FETs for comprehensive characterization, aimed at advancing nanosheet structure and monolithic 3D (M3D) integration technologies. Thermal stability and composition/thickness dependence on device characteristics are systematically explored. Our findings reveal that ALD IZO FETs maintain high thermal stability at temperatures up to 400 °C, and we identify critical trade-offs among key parameters such as mobility, threshold voltage (Vth), and initial Vth shift (ΔVth) under positive bias stress conditions. ALD IZO FETs show higher mobility, lower Vth, and especially smaller initial ΔVth than previously reported our ALD InGaOx (IGO) FETs. These improvements are linked to the intrinsic differences in oxygen dissociation energy between the Zn and Ga in the compound of InOx. The material properties and device behavior of IZO FETs obtained in this work will provide insights for their application in M3D integration.

Thin film absorbers with high performance for millimeter electromagnetic waves are designed using a genetic algorithm. The absorber is a graphite-dispersed siloxane composite multilayer with specific graphite contents. The designed absorber with a thickness of 0.3 mm exhibits an absorptance of more than 20 dB (99%) in the automotive radar frequency band (76 − 81 GHz), and that with a thickness of 0.5 mm exhibits a broadband absorptance of more than 20 dB over the W-band (75–110 GHz). These films can contribute to the stable operation of advanced driver assistance systems.
Pharmacological management of diabetes in older adults

Published: January 2025

As the global population continues to age, the rising prevalence of diabetes among older adults has become a significant public health concern. Consequently, effective and safe management of diabetes mellitus in this population is an increasingly critical focus in clinical practice. Older patients present considerable variability in functional status, with many experiencing physical disabilities, visual impairments, cognitive decline, or psychological conditions such as depression. Therefore, individualized treatment strategies that consider the presence and progression of geriatric syndromes, comorbidities, and the risk of hypoglycemia are essential for optimizing the pharmacological management of diabetes in older adults.

The work aimed to construct a positive recombinant control sample for the detection of Aujeszky’s disease virus by PCR. The construction of the recombinant positive control was first performed virtually online using the SnapGene software program, and then in vitro using the plasmid vector pTZ57R/T, which is included in the commercial kit for TA cloning "InsTAclone PCR Cloning Kit" (Fermentas, Latvia). As an insert, a 235-bp long fragment of the gene encoding the glycoprotein E of the Aujeszky’s disease virus, obtained by the classical PCR method using the AuDV_gE1_F/R primer system, was used. The resulting amplicon was purified and ligated to the plasmid vector pTZ57R/T, and the constructed plasmid molecule was integrated into the culture of competent cells of E. coli strain DH5a. After the transformation, 10 white single colonies of E. coli were selected according to the marker of selective traits, 5 of which were cultivated in a liquid nutrient medium in order to obtain bacterial biomass of E. coli. The developed bacterial mass was used for plasmid extraction. The positive result of our work was confirmed by electrophoretic analysis in 1.5% agarose gel and determination of DNA concentration. The ampicillin-resistant clone of E. coli DN5α developed by us, transformed with the constructed plasmid pTZ57R/T_AuDV with the insertion of a fragment encoding the glycoprotein E of Aujeszky’s disease virus, 235 bp in length. It can be used as a positive control sample for the detection of the genetic material of Aujeszky’s disease virus by PCR

Published: January 2025

A diagnostic kit "Chlamydia-DNA-test" is proposed for the detection of chlamydial genetic material in samples of clinical animal material based on polymerase chain reaction (PCR) in real time. The purpose of the work was to establish the validation characteristics of the created set according to indicators of diagnostic sensitivity, specificity and reproducibility. According to the results of the evaluation of the test system, high sensitivity, specificity and reproducibility were confirmed. The detection limit of the developed technique was 12.5 DNA copies per reaction. The test of the experimental series of the test system in three repetitions showed the reproducibility of the proposed amplification protocol. The absence of amplification product formation in negative samples proves the specificity of the indicated diagnostic kit. “Chlamydia-DNA-test” regarding of its specificity, sensitivity, and reproducibility corresponds to the recommendations set forth in the OIE manual, and after state registration can be proposed for wide implementation in the practice of veterinary medicine, which will significantly increase the efficiency of laboratory diagnostics of chlamydiosis in Ukraine

The aim of the work was to carry out a sanitary and hygienic assessment of the hatchery environment, to determine the level of microbial contamination of poultry facilities, to establish the level of microbial contamination of the surface of the cells of cardboard cells in which eggs of various types of poultry are transported to places of incubation. To determine the degree of microbial contamination of the surfaces, we took the swabs from the inner parts of the incubation cabinets (doors, walls) and the surface of the egg shells with a sterile tampon with physiological solution. Samples were inoculated on nutrient and elective media in order to determine the number of colony-forming organisms. It has been established that contamination level of the surfaces of the premises, equipment, eggshells, swabs from the hatcher walls and the fluff collection room in production conditions ranges from ≥ 104 to 8.1×102 CFU/cm2. In the chick sorting room, during the study of swabs from the walls and air duct, cultures of Bacillus spp., Corynebacterium spp., Proteus vulgaris, Staphylococcus spp. were isolated at a level of ≥ 104 CFU/cm2. On the feeder belt, the contamination level was 3.1×102 CFU/cm2, on the surface of the egg and the saddle cover — ≥ 104 CFU/cm2. The following cultures were isolated: Candida spp., Escherichia coli, Corynebacterium spp. The degree of contamination of the surface of the poultry house egg collector, as well as the walls, egg sorting table of the egg store was almost at the same level (≥ 104 CFU/cm2), isolated cultures: Candida spp., Escherichia coli, Staphylococcus spp., Bacillus spp. A high level of microbial contamination after a single use of cardboard pads during transportation of hatching eggs to the hatching sites has been determined, namely 5.5×102–1.1×104 CFU/cm2. With repeated use of containers, the degree of contamination increases almost 40 times (from 1.1×105 CFU/cm2 for chicken eggs to 120.00×104 CFU/cm2 for duck eggs). Bacilus spp., Corynebacterium spp., Proteus vulgaris, Candida spp., Staphylococcus spp., Escherichia coli microorganisms in the amount of ≥ 104 CFU/cm2 have been detected. The fungal microflora found on the surface of the eggs was represented by Candida spp., Aspergillus flavus in the amount of 0.925×104 CFU/cm2. The level of bacterial and mycotic contamination of the surface of cardboard cells after their one-time use during the transportation of hatching eggs to the places of incubation was 5.5×102–1.1×104 CFU/cm2. In the case of repeated use of containers, the degree of contamination increased almost 40 times
