Az oktatói személyiség sajátosságai a vasútszakmában
Authors: Farkas Attila , Filep Roland , Dajnoki Krisztina
Published: June 2023

Évtizedek óta keresik a kutatók és a gyakorlati szakemberek arra a napjainkban is aktuális kérdésre a választ, hogy mitől „jó”, azaz eredményes és hatékony egy pedagógus. A válasz az oktató személyiségével, személyiségjegyeivel kapcsolatos területeket is magában foglal. Kutatásunk során célul tűztük ki a vasútszakmai oktatók személyiségének vizsgálatát. Részcéljaink között szerepelt az általános személyiségjegyek Big Five modellel történő elemzésén túl, az oktató asszertivitásának, az emberekhez való alaphozzáállásának, befolyásolási technikájának és konfliktuskezelési módjának a tanulmányozása. A saját vizsgálatot kérdőíves módszerrel, széles körben alkalmazott eszközökkel végeztük négy különböző szervezetnél. A csoportok közötti eltérések vizsgálatához varianciaanalízist alkalmaztunk. Az eredmények alapján az oktatók megfelelő alapokkal rendelkeznek a pozitív légkör kialakításához. Nyitottság, barátságosság és az asszertivitás közepesnél erősebb szintje jellemző rájuk, a Machiavellizmus pedig csak kis mértékben van jelen. Konfliktuskezelésben a kompromisszumkeresés, a problémamegoldás és az elkerülés a legjellemzőbb stílusok. Az eredmények alapján javasoljuk a nyitottság és az asszertivitás szintjének további növelését, kompromisszumkeresés helyett pedig a komplex problémamegoldás gyakoribb alkalmazását.

Aprendendo dos Distritos LIFECA em Moçambique
Authors: Uandela André , Coultas Mimi
Published: June 2023

Moçambique comprometeu-se a prosseguir o Objectivo de Desenvolvimento Sustentável da ONU (ODG) 6.2 com vista a alcançar o acesso ao saneamento e higiene adequados e equitativos para todos e acabar com o fecalismo a céu aberto até 2030. No entanto, ainda há muito a ser feito. Dados recentes indicam que 36 por cento da população (11,6 milhões de pessoas) ainda utilizam instalações não melhoradas que não foram concebidas para impedir higienicamente o contacto humano com excrementos. Além disso, Moçambique tem uma elevada taxa de fecalismo a céu aberto, situada em 23 por cento (7,1 milhões de pessoas). A prevalência de práticas sanitárias pouco seguras, como a utilização de instalações sanitárias não melhoradas ou fecalismo a céu aberto, é particularmente elevada nas zonas rurais, onde se verifica uma alarmante falta de acesso a instalações sanitárias seguras por parte de 75 por cento da população. Com base nestas tendências, prevê-se que Moçambique não alcançará um estatuto de país livre do fecalismo a céu aberto até 2068. Com vista a acelerar o alcance de melhores resultados, o Governo de Moçambique (GdM) aprovou recentemente a Estratégia de Saneamento Rural (2021-2030) que visa eliminar a defecação aberta e alcançar o acesso universal ao saneamento básico até 2030 utilizando o Saneamento Total Liderado pela Comunidade (CLTS) como abordagem central. Como parceiro-chave do GdM no subsector do saneamento rural, o UNICEF tem apoiado programas de saneamento em grande escala em várias províncias.

Osmoderma eremita and Cerambyx cerdo are saproxylic beetle species, included in the IUCN Red List and in the EU/92 Habitats Directive. Their occurrence has been recorded, through appropriate traps, in several localities in Italy, including urban and peri-urban parks, mostly associated with veteran trees. In this study, traps were tested over 17 veteran oak trees in the Castelporziano Presidential Estate (Latium, Rome province, central Italy) and the abundance of sampled saproxylic beetles was related to the growing stock volume (GSV) and the abundance of microhabitats. Moreover, we compared three different trapping methods: a trap designed to monitor C. cerdo (CC), and two traps designed for monitoring O. eremita, i.e., the Black Cross Window Trap (BCWT) and the Black Bottle Traps (BBT). We found that larger trees hosted a great variety of microhabitats, in particular cavities, which abundance was correlated with the number of specimens sampled, especially O. eremita species. Both classic traps (i.e., CC traps and BCWT) and the herein-introduced BBT variants were effective for capturing large saproxylic beetles. In this work, we underline the importance of the preservation of veteran trees to the occurrence of threatened saproxylic beetles, and we contributed to (i) extending general knowledge of the habitat preferences of saproxylic beetles and (ii) improving new cost-effective trapping system variants. Key Words: Osmoderma eremita, Cerambyx cerdo, IUCN threatened species, Tree-related Microhabitat, urban and peri-urban areas, veteran trees

Published: June 2023

A 24-year-old man suffered a witnessed cardiac arrest after a padel game. Basic life support was immediately provided. The pre-hospital emergency services team continued the resuscitation efforts, and the patient was accepted for extracorporeal cardiopulmonary resuscitation. The return of spontaneous circulation was achieved in 45 minutes. The initial assessment revealed a ST-segment elevation in leads V4-V6 and a dilated left ventricle with severe systolic dysfunction. Coronary angiography was normal. An improvement in left ventricular systolic function was observed and extracorporeal cardiac support was discontinued after 48 hours. Cardiovascular magnetic resonance imaging demonstrated hypokinesia and subepicardial fatty infiltration of the left ventricle lateral wall. Genetic testing detected a variant of uncertain significance in the ANK2 gene. The diagnosis of arrhythmogenic left ventricular myocardiopathy did not fulfill all the current diagnostic criteria, but it is a very likely diagnosis. An implantable cardioverter-defibrillator was placed. Thepatient was discharged without physical or cognitive impairment.

The use of restricted activity to identify global decline in multimorbidity: current evidence and the potential of a connected health approach
Authors: Henderson Ishbel L. , Sheppard James P. , Barnes Rebecca K. , McManus Richard J.
Published: June 2023

There is a rising problem of multiple long-term conditions (“multimorbidity”) as the global population ages. Old age is the biggest risk factor for having one or more chronic conditions. Unfortunately, current care processes can be fragmented, with most focusing on individual diseases. This can lead to unintended consequences for patients, particularly if they are admitted onto an inappropriate care pathway, along with subsequent economic downsides. When people with multiple long-term conditions deteriorate, detection of illness may be delayed due to a range of non-specific symptoms being displayed. At present, there is limited research on detecting deterioration within community settings, thereby forming the basis of earlier interventions. A general measure, such as how active an individual is, might allow initial identification of decline and trigger a more targeted approach to assess the underlying reason for deterioration. Restricted activity seems to manifest earlier than the routinely used single condition clinical markers, and has been identified both in the last year of life and during periods of illness. Changes in activity could facilitate the identification of illness, leveraging technology to determine any decline. However, there is still no universally agreed definition of what constitutes a change in activity and, therefore, no accepted method of measuring it. This paper reviews the potential for a connected health approach to monitoring older adults with multimorbidity, using restricted activity as a general measure of health decline.
METHOD OF QUALIFICATION OF PASSIVE SAFETY SYSTEMS OF MODULAR NUCLEAR REACTORS WITH CIRCULATION CIRCUIT FLOWS
Authors: Skalozubov Vladimir , Pis'mennyi Eugene , Kondratyuk Vadym , Kosenko Sergei , Konshin Valeriy
Published: June 2023

Low-power modular reactors are a promising direction for increasing the safety of nuclear power, because accident management in modular reactors is carried out only by passive safety systems (without electric pumps). Critical for the safety of modular reactors are accidents with a violation of the tightness of the natural circulation circuits of passive safety systems. The main limitations of using traditional accident modeling approaches with deterministic codes to qualify the reliability and operability of passive safety systems of modular reactors are related to the possibility of negative effects of "code differences" and "code user differences", as well as the unfoundedness of code verification/validation results. An original qualification method has been developed to ensure the safety conditions of the passive safety systems of the Westinghouse low-power modular reactor (SMR) in the event of accidents with a violation of the tightness of the natural circulation circuits. The assumptions adopted in the developed method ensure the conservatism of qualification results. Based on the preliminary calculation qualification of the natural circulation circuits of the SMR passive safety systems, it was established that for the relative sizes of the leaks, greater than 5% of the pipeline cross-section, a violation of safety conditions and drainage of the active zone may occur less than 24 hours after the start of the accident. It is necessary to modernize the SMR with regard to systems for diagnosing leaks in natural circulation circuits of passive safety systems and isolating damaged sections of circuits.

Published: June 2023

The purpose of the publication is to develop a methodology for presenting the unit "6 kV compressor-synchronous electric motor" in the form of a finite state machine.

It is hypothesized that the behavior of the compressor unit can be associated with the behavior of an abstract deterministic finite state machine.

The theory of finite state machines and graphs is applied to analyze the operation of a compressor installation using the example of a compressor of a large-tonnage shop for the production of ammonia. It is shown that the theory of finite state machines allows combining all possible modes of operation and shutdown of compressor units. Coding of reasons for compressor shutdown due to problems in the electrical or mechanical parts of the compressor unit is proposed. A diagram of state transitions has been developed for it. Such a diagram can be useful for compiling a concise description and understanding of the operation of a compressor unit,  advanced training of technological personnel during industrial training, for emergency training, etc.

A graphical analysis of the obtained diagram was carried out. The optimal (most perceived in terms of energy efficiency) route of the graph is determined.

The proposed form of abbreviated recording of the compressor operation cycle and the electronic mileage log, which allows you to calculate the remaining resource of the compressor installation and the compressor operation time.

The implemented methods make it possible to identify bottlenecks in the complex electrical and technological equipment of industrial enterprises.

Published: June 2023

This article analyzes the operation of a solar energy system installed in a higher education institution, consisting of four photovoltaic stations connected to the electrical grid for self-consumption, and a solar hot water system with collectors and a storage tank. The operation of the system was modeled using the RETScreen, T*SOL, and PV*SOL software programs, based on averaged climate data obtained from the "Zhuliany" weather station. The solar system is installed on the south-facing roof of the building and consists of 262 monocrystalline silicon photovoltaic modules of Trina Solar TSM-DE08M (II) type with a power of 370 W, installed at an angle of 30° to the horizon, and 8 Veissmann Vitosol 300-T SP3 vacuum tube collectors with a power of 1.3 kW installed at an angle of 35°. The placement of the solar elements was determined through modeling, considering their dimensions, the features of the roof structure, the placement of ventilation systems, and the shading of the roof surfaces by other elements of the building in Kyiv. As a result of energy modeling, it was determined that the amount of thermal energy obtained is 6.823 MWh/year, and the amount of electrical energy is -109.16 MWh/year, with a total inverter capacity of 95 kW, a traditional fuel replacement coefficient of 50% for the photovoltaic system and 75% for the solar system with collectors, payback periods of 4.3 years for the photovoltaic system, and 13 years for the hot water system when replacing electric boilers and 16 years when obtaining hot water from a district heating network. The reduction in harmful emissions is 45 tons/year of CO2, which is equivalent to 104.3 barrels of crude oil or 19,279 liters of high-octane gasoline or 15.5 tons of recycled waste. Based on the analysis of the data, it is recommended to install such systems in higher education budget institutions to reduce electricity or natural gas consumption and reduce harmful emissions into the environment.

Authors: Konshin Valerij , Kviatkovskyi Bohdan
Published: June 2023

This article studies the future development of the energy industry with the aim of reducing greenhouse gas emissions. Three different options for planning the use of electricity-generating enterprises and determining the most optimal for the environment and economy of the country based on graphs of the dynamics of greenhouse gas emissions into the atmosphere are considered. The assessment and selection of the most optimal option is based on the Low-Carbon Development Strategy of Ukraine.

The types of electricity generation that most pollute the environment and those that practically do not pollute have been determined. The share of produced electricity accounted for by each type of generation and the dynamics of electricity production in recent years were considered in percentage terms. Also, this article provides an example of one of the countries abandoning nuclear energy, and what consequences this had for the energy balance and the development of a low-carbon economy. The most appropriate option for the development of power plants in Ukraine was determined and it was considered how in the future it is possible to increase the share of electricity produced at nuclear power plants and reduce the share of electricity produced at thermal power plants. The development of nuclear energy has a positive effect on the country's energy independence, so it must be developed and, if possible, switched to new types of reactors in order to make energy even more secure.
RESEARCH OF VALVE MOTOR CONVERTER CONTROL METHODS
Authors: Zakladnyi Oleg , Prokopenko Volodymyr
Published: June 2023

A technique for selecting the electrical equipment of a valve motor with machine commutation has been developed, which takes into account the ways of controlling the inverter. The installed capacity of the electrical equipment of the valve motor (VD) is determined by technological requirements and depends on the structure of the converter, the method of commutation of the converter keys and the methods of controlling the inverter. The use of autonomous inverters with artificial switching, the keys of which are switched due to the reactive energy accumulated in additional switching devices, increases the utilization factor of the synchronous machine. However, in this case, the circuit becomes more complicated and the installed power of the converter increases. The use of IGBT transistors and IGCT thyristors leads to a significant increase in the cost of the equipment.

To reduce the influence of the rectifier VD on the network and match the drive voltage with the supply voltage, a matching transformer and reactive power compensation device may be needed. The amount of power of this equipment is affected by the method of controlling the rectifier, the nature of the engine load and the range of speed changes.

Voltage regulation of the rectifier can be symmetrical or asymmetrical. Several methods of asymmetric regulation are known, among which one of the most expedient is alternating. In the case of alternating control in the three-phase bridge circuit, an artificial zero circuit is created, as a result of which the duration of the current flowing through the secondary windings of the transformer becomes less than 2/3 of the half-cycle of the supply voltage. In addition, the energy indicators also increase, in particular, the reactive power consumption decreases and the shift and power coefficients increase.

Published: June 2023

This study proposed the use of forecasting methods based on artificial neural networks for calculating and forecasting energy losses. The calculation of energy losses was performed on the CIGRE test network. Several approaches were developed to determine energy losses: prediction of electrical energy losses using artificial neural networks, and calculation of losses using nodal load prediction based on artificial neural networks, which were compared with the classical method of calculating losses based on summer and winter peak load coefficients. Depending on forecasting problems, when using artificial neural networks, the amount of electrical energy losses in distribution networks decreased by three times compared to the calculation of losses using coefficients.
METHOD OF IDENTIFYING HAZARDS AND PREDICTING THE EMERGENCY SITUATIONS IN CASE OF SOIL CONTAMINATION BY HEAVY METAL COMPOUNDS
Authors: Panasiuk І. , Tretiakova L. , Mitiuk L.
Published: June 2023

Purpose. The goal of the article is to develop a method for identifying hazards and predicting the possibility of a technogenic emergency caused by the spread of compounds with heavy metals in the soil during long-term storage of galvanic sludge in open areas.

Methodology. The method is developed on the basis of a mathematical model that allows estimating changes in the depth of distribution and level of soil salinity over time using initial information about soil structure and its characteristics (molecular diffusion coefficient, volume humidity), annual volumes and conditions of sludge storage in the enterprise. Restrictions are set: the presence of harmful substances on the soil surface with a concentration that exceeds the permissible level; inadmissibility of harmful substances to aquifers.

Results. The practical use of the method made it possible to identify the main dangers and predict the possibility of an emergency situation with negative environmental consequences during long-term storage of galvanic waste in open areas. The dynamics of soil salinity levels and the depth of penetration of heavy metals increase over twenty years of conservation has been determined, as well as the possibility of hazardous compounds entering groundwater has been assessed.

Originality. The non-linear, non-stationary mathematical model is based on the theory of physico-chemical hydrodynamics of cellular media. The process of motion of metal salts has been described by the differential equation of motion and conservation of mass of matter for vertical mass transfer of matter.

Practical value. Formalization of information about the hazards arising during the storage of industrial waste with chemically active elements allows to consider the subject area as a complex dynamic system consisting of objects of different nature, the totality of which determines the level of danger of emergencies with environmental consequences. The developed method makes it possible to transfer the obtained results to decision-making support systems, predicting possible consequences and material costs associated with post-emergency measures, motivating the management to take measures in advance.

OVERVIEW OF FACTORS AFFECTING THE ESTIMATION OF LIGHTNING SHIELDING PERFORMANCE OF OVERHEAD TRANSMISSION LINES
Authors: Trotsenko Y.O. , Peretyatko J.V. , Dixit M.M. , Hohol V.V.
Published: June 2023

This paper examines the risk of lightning stroke to overhead transmission line. The estimation procedure for the lightning performance of overhead power lines is based on the selected lightning attachment model, available lightning parameter statistics, the transmission tower design and voltage levels, type of overvoltage and other characteristics. In this paper the overview of factors affecting the estimation of lightning shielding performance of overhead transmission lines was performed. Among the factors that can affect the estimation accuracy, one can list insufficiently accurate data on the ground flash density in the area of interest and lack of complete data on statistical distribution of lightning current magnitudes. The paper shows that the influence of wind on the increase in the horizontal exposed distance of the phase conductor is not also taken into account. In this research traditional electro-geometric model was used for estimation of lightning performance of 220 kV overhead power line. Results obtained suggest that swing of suspension insulator strings caused by strong winds may lead to increased risk of lightning shielding failure during thunderstorm. Calculation performed for 3 kA lightning current magnitude shows that at swing angle equal to –1 degree, the horizontal unprotected distance of phase conductor increases by 3.1%, that corresponds to 5.240 m uncovered width. When the swing angle is increased to –5 degree, the uncovered width is increased by 15.8% that corresponds to 5.885 m uncovered width. It is proposed that an increase in the risk of lightning shielding failure as a result of wind load can be accounted by applying an appropriate correction factor in expressions for calculation of shielding failure rate, shielding failure flashover rate, etc. Proposed correction factor should account frequency and strength of wind in the area of transmission line route and depend on transmission line voltage level and tower design. Further efforts should be focused on obtaining and justifying the numerical values ​​of this correction factor.

Authors: Fawzy Amal , El-Shami Ahmed , Ahmad Seleem
Published: June 2023

In this work the effect of recycled concrete aggregate modified with mineral admixtures and Nano-silica on the mechanical properties and performance of the concrete was investigated after curing in tap water for 28 and 90 days. The compressive, ƒc, indirect tensile, ƒt, and flexural, ƒb, strengths for cured concrete specimens were measured and concrete strength ratios were analyzed. The water and rapid chloride permeability were measured. SEM analysis of microstructure was, also, investigated. The coarse aggregates used were dolomite (control) and recycled concrete aggregate with the incorporation of different mineral admixtures including ground granulated blast slag and granite as well as Nano-silica. It was found that, the slump values of the dolomite concrete decreases compared with recycle aggregate concrete. The results indicate that, the concrete mix containing recycle aggregate have the highest compressive strength, tensile strength and flexural strength compered to concrete mix containing dolomite aggregate. As far as the compressive strength is concerned, the addition 1 % NS and 15 % of slag improved the physico-mechanical properties of the recycled aggregate concretes compared to the other mixes after curing in tap water.

The UK aviation industry is committed to achieving net zero emissions by 2050 through sustainable measures, and one of the key aspects of this effort is the implementation of Unmanned Traffic Management (UTM) systems. These UTM systems play a crucial role in enabling the safe and efficient integration of unmanned aerial vehicles (UAVs) into the airspace. As part of the Airspace of the Future (AoF) project, the development and implementation of UTM services have been prioritized. The paper aims to create an environment where routine drone services can operate safely and effectively. To facilitate this, a digital twin of the National Beyond Visual Line of Sight Experimentation Corridor has been created. This digital twin serves as a virtual replica of the corridor and allows for the synthetic testing of unmanned traffic management concepts. The implementation of the digital twin involves both simulated and hybrid flights with real drones. Simulated flights allow for the testing and refinement of UTM services in a controlled environment. Hybrid flights, on the other hand, involve the integration of real drones into the airspace to assess their performance and compatibility with the UTM systems. By leveraging the capabilities of UTM systems and utilizing the digital twin for testing, the AoF project aims to advance the development of safer and more efficient drone operations. Experimentation Corridor has been developed to simulate and test concepts related to managing unmanned traffic. The paper provides a detailed account of the implementation of the digital twin for the AoF project, including simulated and hybrid flights involving real drones.

The purpose of this article is to conduct a bibliometric review of literary production in terms of market interdependence. We investigate the effect of contagion on agricultural commodities and identify the commodities and methods used in the most cited publications over the decades. For this, we used the SCOPUS database, sorting with Rayyan, Excel, and finally, the Bibliometrix/R-project. The results showed that corn, wheat, soybeans, cotton, and sugar are the most studied commodities. There is no uniqueness concerning the methods used to identify interdependence and the contagion effect. Also, it is possible to perceive the growing scientific interest concerning the subject, with a diversity of authors and magazines. However, there is a direction of the and magazines most cited articles for analyzing agricultural commodities and energy, demonstrated a worldwide trend of studies relating natural resources, biofuels, clean energy, and efficiency. In addition, countries like China and the United States stand out in this scientific scenario as the countries that produce the most articles.

Humans’ performance varies due to the mental resources that are available to successfully pursue a task. To monitor users’ current cognitive resources in naturalistic scenarios, it is essential to not only measure demands induced by the task itself but also consider situational and environmental influences. We conducted a multimodal study with 18 participants (nine female, M = 25.9 with SD = 3.8 years). In this study, we recorded, respiratory, ocular, cardiac, and brain activity using functional near-infrared spectroscopy (fNIRS) while participants performed an adapted version of the warship commander task with concurrent emotional speech distraction. We tested the feasibility of decoding the experienced mental effort with a multimodal machine learning architecture. The architecture comprised feature engineering, model optimisation, and model selection to combine multimodal measurements in a cross-subject classification. Our approach reduces possible overfitting and reliably distinguishes two different levels of mental effort. These findings contribute to the prediction of different states of mental effort and pave the way toward generalised state monitoring across individuals in realistic applications.

Immune cells such as T cells and macrophages express α7 nicotinic acetylcholine receptors (α7 nAChRs), which contribute to the regulation of immune and inflammatory responses. Earlier findings suggest α7 nAChR activation promotes the development of regulatory T cells (Tregs) in mice. Using human CD4+ T cells, we investigated the mRNA expression of the α7 subunit and the human-specific dupα7 nAChR subunit, which functions as a dominant-negative regulator of ion channel function, under resting conditions and T cell receptor (TCR)-activation. We then explored the effects of the selective α7 nAChR agonist GTS-21 on proliferation of TCR-activated T cells and Treg development. Varied levels of mRNA for both the α7 and dupα7 nAChR subunits were detected in resting human CD+ T cells. mRNA expression of the α7 nAChR subunit was profoundly suppressed on days 4 and 7 of TCR-activation as compared to day 1, whereas mRNA expression of the dupα7 nAChR subunit remained nearly constant. GTS-21 did not alter CD4+ T cell proliferation but significantly promoted Treg development. These results suggest the potential ex vivo utility of GTS-21 for preparing Tregs for adoptive immunotherapy, even with high expression of the dupα7 subunit.

Understanding maturation stress and wood properties of poplar tension wood are critical for improving lumber yields and utilization ratio. In this study, Released Longitudinal Maturation Strains (RLMS), anatomical features, physical and mechanical properties, and nano-mechanical properties of the cell wall were analyzed at different peripheral positions and heights in nine inclined, 12-year-old poplar (Populus×euramericana ‘Zhonglin46’) trees. The correlations between RLMS and wood properties were determined. The results showed that there were mixed effects of artificial inclination on wood quality and properties. The upper sides of inclined stems had higher RLMS, proportion of G-layer, bending modulus of elasticity, and elastic modulus of cell wall but lower microfibril angle than the lower sides. At heights between 0.7 m and 2.2 m, only the double wall thickness increased with height, RLMS and other wood properties such as fiber length and basic density fluctuated or changed little with height. RLMS was a good indicator of wood properties in the tension wood area and at heights between 0.7 m and 1.5 m. The results of this study present opportunities to identify and select better quality wood in poplar trees.
An Explainable Vision Transformer Model Based White Blood Cells Classification and Localization

Published: June 2023

Blood cell analysis is a crucial diagnostic process in medical practice. In particular, detecting white blood cells (WBCs) is essential for diagnosing of many diseases. The manual screening of blood films is a time-consuming and subjective process, which can lead to inconsistencies and errors. Therefore, automated detection of blood cells can improve the accuracy and efficiency of the screening process. In this study, an explainable Vision Transformer (ViT) model was proposed for the automatic detection of WBCs from blood films. The proposed model utilizes the self-attention mechanism to extract relevant features from the input images and leverages transfer learning by incorporating pre-trained model weights to improve its performance. The proposed model achieved a classification accuracy of 99.40% for five distinct types of WBCs and exhibited potential in reducing the time required for manual screening of blood films by pathologists. Upon examination of the misclassified test samples, it was observed that incorrect predictions were correlated with the presence or absence of granules in the cell samples. To validate this observation, the dataset was divided into two classes, namely Granulocytes and Agranulocytes, and a secondary training process was conducted. The resulting ViT model trained for binary classification achieved an accuracy of 99.70%, recall of 99.54%, precision of 99.32%, and F-1 score of 99.43% during the test phase. To ensure the reliability of the ViT model's multi-class classification of WBCs, the pixel areas that the model focuses on in its predictions are visualized through the Score-CAM algorithm.
