Authors: YILMAZ Kadir , DİNDAR Taner , AYAZ Murat , AKTAŞ Serkan , SEZEN Serkan
Published: January 2024

The utilization of gears as intermediary components for power transmission in electric drive systems addresses the insufficiency of electric machines in handling torque loads effectively. Gears, commonly employed in the industry, can be either mechanical or magnetic, allowing for the balanced transfer of torque and speed at specified ratios. The mechanical and electrical actuation of in-vehicle accessories persists both in traditional and next-generation vehicles. Particularly concerning safety and the sustainability of spare part production and supply, various electrical accessories continue to operate at the 12 V level in modern vehicles. In this context, the use of the Lundell alternator (claw pole) also continues in next-generation vehicles. While the mechanical accessories are driven by a belt-pulley system connected to an internal combustion engine in conventional vehicles, in next-generation vehicles, both belt-pulley systems and x-drive by wire are present. The low efficiency and operational costs of belt-pulley power transmission systems necessitate the adoption of more efficient transmission systems. This study focuses on the development of a soft magnetic composite (SMC) core magnetic gear power transmission system that can serve as an alternative to belt-pulley systems in both traditional and next-generation vehicles. In the proposed system, mechanical power transfer to the Lundell alternator is realized through the intended magnetic gear. The gear ratio is determined to ensure a speed of 1800 rpm at the input of the Lundell alternator while the drive system operates at 6000 rpm. To achieve low volume and high efficiency for the proposed magnetic gear, the SMC material is considered, and a comprehensive analysis using the Ansys Maxwell finite element software is conducted. As a result of the analyses, in the magnetic gear designed with a transmission ratio of 3:1, when a torque of 11.7547 Nm is applied to the input shaft, a torque transmission of 35.9806 Nm has been achieved with an efficiency of 84.73% through the output shaft.
In Ukraine or on Ukraine: the Great Russian chauvinism from the linguistic perspective
Authors:   National Academy of the Security Service of Ukraine, Fedorenko Lesia
Published: January 2024

This article is determined to analyze the way Russian political and ideological system is using linguistics in the means of its informational and psychological aggression against Ukraine. The war launched by Russian Federation has become the culmination of its prolonged aggressive actions on many fronts: ideological, economical, cultural, linguistic and so on. Current cremlin hosts are trying to regain full control over Ukraine in every imaginable way, drawing on the previous political regimes' experience. This article investigates one of the definitions of chauvinism as harassment of so-called "small nations" on the domestic and international levels that is shaping into political oppression and assimilation of languages. Have it that cremlin ideologues have always exploited any opportunity to diminish Ukrainians' self-consciousness, in particular by means of different quasi-scientific theories. Here we explored one example of the forementioned such as the creation of fake exception to the rule of spelling of prepositions "in" and "on" with administrative geographical names by Russian philologers that only applied to place-name "Ukraine". In contradiction to linguistic norms of Russian language Russians use "on Ukraine" in accusative and locative cases. We respectively analyzed arguments of Soviet linguists D. Rozental and K. Bilinskyy, and also modern Russian geographers and their theory of geo concept that basically comes to one statement: such version has been made up through history and is backed up by the expression "on the outskirts". The Ukrainian linguist I. Ohiyenko's work, in which he explained that the expression "in Ukraine" positioned it as a separate state, is mentioned in the article. After the collapse of the Soviet Union the logical norm "in Ukraine" was being used in the official documents of Russian Federation for a while, but after the cremlin tacked its course to re-establish its dominance over the former Soviet republics, they returned to the previous version. The sources that have been studied in the article point out that the political and ideological system is of a paramount importance for Russian linguistic science and is using it as a non-lethal weapon against Ukraine.
Gustatory vocabulary in luxury food advertising (based on FORTNUM & MASON and FORMAN & FIELD websites and social media platforms)
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Belova Alla
Published: January 2024

The article highlights gustatory lexicon usage in advertising top quality foods by the two famous British shops – Fortnum & Mason (F&M) and Forman & Field (F&F). Advertising luxury goods, including fine foods, requires elegant style, refined vocabulary, particular argumentation and persuasion strategies, the need to communicate taste and flavour parameters precisely and efficiently. Textual description of luxury foods was studied to reveal how gustatory modality is packaged in English on the shops' websites and social media platforms. Taste, smell, touch as sensory sensations attract a lot of attention lately in Sensory Linguistics, Culinary Linguistics, Cognitive Linguistics, Multimodality Studies and Discourse Analysis. The article deals with the sensory vocabulary of English, with language units used to express gustation, "taste" words combinability and frequency, and overlapping zones of gustatory modality and olfactory, tactile, audio modalities when these sensations impact flavour. The research proved that basic taste terms – taste, salty, bitter, sour – that are used for conceptualization and categorization of sensory sensations are seldom used in promotion of fine foods; "flavour" is obviously preferable to "taste"; one of the basic taste terms – "sweet" – enjoys high frequency. Advertising foods on websites is more detailed and saturated with gustatory terms in comparison with promotion of the assortment on Facebook and Twitter. The adjective "delicious" and its derivatives remain the most frequently used words to characterize high quality of the luxury foods and delicious taste indicators. F&M's gustatory lexicon turned out more diverse than F&F's. Source-based taste words are used to denote the ingredients that predetermine the flavour. Flavour of F&M's foods is conceptualized and emphasized through –ness nouns. Intensifiers – derivatives of taste words and non-taste words – accentuate the flavour parameters. English gustatory lexicon is extended considerably through 'non-taste' adjectives with the positive evaluative meaning. Though gustation and olfaction are considered to be interconnected when tasting and eating food, olfactory modality is rarely found in foods descriptions while texture and freshness of some foods become of special importance.

The article deals with the investigation of perfume advertisement in the aspect of its semiotic mode cooperation and interactions which are reflected as cohesion within one and the same semiotic mode and between different semiotic modes as well. The objects of the research are perfume advertisements and their formal elements which create the semiotic structure. Within the verbal semiotic mode, such leading formal elements as functional blocks, subblock names and their lexical embodiment were distinguished. The most developed functional block contains name, naming complex with A-1 brand (company), B-2 individual name, C-3 genitive (product) name, and D-4 additional information. These names are the key markers of lexical cohesion. Lexical cohesion within the verbal semiotic mode is realised through the mechanism of reiteration, including repetition and synonym usage. Lexical cohesion occurs within one and the same functional block as well as between different functional blocks. Within the visual semiotic mode, there are such formal elements as composition, plan, balance, and depth. The advertisement visual semiotic mode has such a set of parameters as a plan, visual component, variable and constant details of a visual component. The advertisement depth is realised using front, middle, and back plans. The main visual components are a perfume bottle, model and scenery. The model has the most detailed visual representation including the model's image, code of costume, and code of behaviour (grasping body language – pose, imitation of behaviour and facial expression). Colour as a media language is closely connected with the process of visualisation and occurs in all visual components providing visual repetition as a basic colour or its shade. Visual components (objects) are repeated in different plans, providing further cohesion between different plans. There is a definite correlation between verbal components-naming units and their visualisation. It is the case of further cohesion between verbal and visual semiotic modes. The olfactory semiotic mode uses the mechanism of synaesthesia when smell is represented involving verbal description and optical visualisation but this aspect of research needs more detailed investigation and deeper revealing and analysis.

Aim: to assess associations between folate cycle gene polymorphism and neonatal birth weight in pregnant women with fetal growth retardation (FGR) and related functional effects in population of the Central Black Earth Region.

Materials and Methods. 98 cases of women with FGR were enrolled to a retrospective molecular and genetic screening to assess prevalence 5 SNPs (single nucleotide polymorphisms) in genes involved in folic acid cycle and methionine metabolism (rs699517 TYMS, rs2790 TYMS, rs1979277 SHMT1, rs1805087 MTR, rs1801394 MTRR).

Results. It was found out that allele A of the rs1801394 MTRR was associated with a lower neonatal birth weight (recessive model: β = –0.34 ± 0.13; p = 0.009). This polymorphic locus exerts crucial functional effects by determining the amino acid substitution in methionine synthase reductase (Ile22Met) localized in the region of modified histones, which mark enhancers and promoters in ectoderm, endoderm and mesoderm cell cultures, primary osteoblast cells, brain, fat nuclei, skeletal muscles, etc. In addition, rs1801394 MTRR is found DNA sites (motifs) responsible for sensitivity to transcription factors STAT and TBX5 being also related to MTRR gene mRNA expression level in subcutaneous and visceral adipose tissue, thyroid gland, fibroblast cell culture as well as various brain regions.

Conclusion. Thus, the allele A of the rs1801394 polymorphism in MTRR gene is a risk factor for a lower neonatal birth weight.

Authors: Fisenko Natalia V. , Yusef Yusef N. , Subbot Anastasia M. , Osipyan Grigory A.
Published: January 2024

BACKGROUND: Corneal epithelial defect is a corneal epithelial cells’ (CEpC) disruption of various origin. In patients with corneal epithelial defect, glaucoma is a frequent concomitant disease demanding prescription of hypotensive medications, most of which containing benzalkonium chloride.
AIM: The aim of this study is to evaluate cytotoxicity of antiglaucoma drugs, as well as benzalkonium chloride (BAK), to human CEpC in vitro.
MATERIALS AND METHODS: The study was carried out on primary cultures of human CEpC. Cytotoxicity of dorzolamide, brimonidine, timolol (dilutions 1/100, 1/50, 1/20, 1/10, a 24-hour exposure) and of BAK was estimated on the model of intact epithelium (monolayer). Benzalkonium chloride was evaluated in concentrations equals to its concentration in tested ophthalmic solutions. Cytotoxicity of dorzolamide, brimonidine, timolol (dilutions 1/100, 1/20, a 48-hour exposure) was evaluated on the model of corneal epithelial defect (damage of the monolayer). The medication’s cytotoxicity was estimated by cellular changes (phase-contrast microscopy) and by the MTS-test’s results.
RESULTS: Among BAK-free medications: dorzolamide (1/50, 1/20, 1/10 dilutions), brimonidine (1/10 dilution) — induce CEpCs’ pathological changes, whereas timolol (all tested dilutions) is non-toxic. BAK-preserved drugs: dorzolamide, brimonidine, timolol (1/100, 1/50, 1/20, 1/10 dilutions) — induce CEpCs’ damage, their viability reduction, and corneal epithelial defect closure inhibition. BAK shows similar effect in tested concentrations.
CONCLUSIONS: Cytotoxicity of antiglaucoma drugs is attributed to their component — benzalkonium chloride. Administration of preserved drugs is not reasonable in eyes with corneal epithelial defect of various origin.

Published: January 2024

In the practice of an ophthalmic surgeon, patients with a large number of concomitant conditions after repeated surgical interventions are seen with increasingly frequency. One of the grave complications in such patients is secondary glaucoma with a refractory type of course. After successful compensation of intraocular pressure in such patients, the risk of complications increases many times, for example, protrusion of the Ahmed valve drainage tube, which becomes the entrance gate for infection, which can lead to endophthalmitis. This article presents clinical cases of surgical treatment of recurrent protrusion of the Ahmed valve drainage tube.

BACKGROUND: Severe progressive forms of infectious keratitis are often associated with the risk of violation of the structural integrity of the eyeball and the development of endophthalmitis. In the presence of negative dynamics against the background of conservative etiotropic therapy for severe keratitis, it is advisable to use surgical methods of treatment. The combination of two surgical methods of influencing a pharmacoresistant infectious process in the cornea — cross-linking and fulguration — is promising and requires further investigation.
AIM: In the experiment, to evaluate the effect on the corneal tissue of various modes of direct current fulguration, as well as in combination with cross-linking as well.
MATERIALS AND METHODS: An in vivo experimental study was carried out on 19 rabbits (38 eyes) of the Soviet Chinchilla breed, the average body weight of the animals was 2.5–4.0 kg. Depending on the stage of the study, the type and power of exposure during fulguration, the rabbits were divided into 3 groups.
RESULTS: When the cornea was exposed to fulguration in mode 5, the changes covered only 10–15 % of the anterior stroma, about 50 μm, and both clinically and histologically were not sufficient. When exposed to mode 6 and 7 after 3 months, changes in the stromal structure extended by about 150 µm. When using mode 8, there was a slight proliferation of connective tissue between the Descemet’s membrane and the endothelium. The combination of cross-linking with fulguration made it possible to obtain a more compact structure of the anterior layers of the corneal stroma and stability of the epithelium.
CONCLUSIONS: Fulguration may be a relatively safe treatment for the cornea in pharmacoresistant progressive keratitis. Fulguration and corneal cross-linking can potentiate each other’s effect. Fulguration mode 7 (1.5 W) is optimal at corneal exposition for the eradication of infectious agents.

Authors: García Pescador Nicolás , Delgado Barraza Andrés Mauricio
Published: January 2024

Las infecciones osteoarticulares en pacientes pediátricos están asociadas a morbilidad significativa y riesgo de secuelas funcionales o anatómicas, que requieren intervenciones quirúrgicas, en ciertas ocasiones. La sacroileítis piógena (SP) es una infección bacteriana osteoarticular que abarca un pequeño porcentaje del total de las artritis sépticas. La sintomatología es imprecisa, lo que hace retrasar el diagnóstico de la enfermedad y, consecuentemente, llevar a posibles complicaciones como abscesos, sepsis y deformación de las articulaciones. En la actualidad, la resonancia magnética nuclear (RMN) es el método diagnóstico más útil en razón a su relativamente fácil acceso y alta sensibilidad. El inicio del manejo antibiótico adecuado implica una rápida regresión de los síntomas. Presentamos el caso clínico de una paciente escolar atendida en un hospital de Bogotá, Colombia, quien presentó un cuadro de SP, sospechado con base en la anamnesis y examen físico para finalmente ser confirmado por imagenología y cultivo microbiológico.

Background: Paratuberculosis is a chronic infectious disease of wild and domestic ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). The present study aimed to conduct the molecular and serological detection of MAP in ruminants of Jabalpur region. Methods: A total of 261 faecal, 124 blood and 51 tissue samples were collected from goats, buffaloes and cattle of the region irrespective of their age, sex and breed. ZN staining of faecal and tissue samples was performed as a preliminary screening test followed by anti-MAP antibodies detection in serum samples using indirect ELISA and IS900 PCR analysis of ZN positive faecal and tissue samples. Result: A pattern of acid-fast bacilli shedding in faecal samples of ruminants was obtained based on ZN staining with a majority of +1 shedders. In ELISA, 33.87% of serum samples were found positive for anti-MAP antibodies whereas, 22.50% ZN positive faecal samples and 100% ZN positive tissue samples were found positive in IS900 PCR. Therefore, a conclusion of moderately prevalent MAP infection in ruminants of the Jabalpur region can be drawn.
Oxidative Stress: A Biomarker for Animal Health and Production: A Review
Authors: Jain Archana , Shakkarpude Jyotsana
Published: January 2024

Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in body. Body produces free radicals during metabolic processes which are neutralized by antioxidants. However, too many free radicals produced can interfere with cell regeneration and repair, which over time can lead to accelerated aging and the development of certain diseases. Oxidative stress is defined as an imbalance between increased sources of oxidation and decreased or defective antioxidant mechanisms. This definition lends itself to the notion that a special type of mechanism exists and that deviations from this can affect the homeostasis and potentially cause or worsen disease. Oxidative stress plays an important role in the development of chronic diseases such as cardiovascular disease, diabetes, neurodegenerative diseases and cancer. Long-term exposure to high levels of pro-oxidant factors can lead to structural defects at the mitochondrial DNA level and functional changes in several enzymes and cellular structures leading to aberrations in gene expression. As such, many attempts has been made to restore this “balance” by providing antioxidants to animals and human beings to prevent the ill effects of these free radicles produced by the body tissues. Oxidative stress is a disease driver or an epiphenomenon; which worsen the condition in body and the use of antioxidants treatment may prevent some degree of oxidative stress from occurring, which could play an important role in controlling inflammation and cellular adaptive responses.
Inheritance Pattern of A1 Cytoplasmic-nuclear Male Sterility System in Commercial Pearl Millet Hybrids [Pennisetum glaucum (L). R. Br.] in Summer and Post-rainy Seasons
Authors: Kanchana Siva Kumar , Kalra Neetu
Published: January 2024

Background: This study aimed to understand the genetic aspects and inheritance patterns that control the process of restoring fertility in the context of the A1 system of Cytoplasmic-Nuclear Male Sterility (CMS) in pearl millet. Methods: The experimentation was conducted in commercial pearl millet hybrids, utilizing three F2 populations and three BC1 populations. These populations underwent assessment during the rainy and post-rainy seasons at Rallis India Limited, Hyderabad During the Post-rainy (November-February) and summer (March-June) seasons of 2022-2023. Segregation data derived from observations on pollen shedding and seed set were gathered and subsequently, statistical analysis was performed. The Chi-square (χ2) test was employed to assess the conformity of the observed segregation data to the expected genetic ratios, thus evaluating the goodness of fit. Result: The hybrid combinations MP13P025A ×MP16P050R (MP7171) and MP18P069A × MP20P081R (MP7214) consistently displayed a 3:1 segregation ratio in the F2 generation and a 1:1 ratio in the BC1 generation, regardless of the rainy or post-rainy seasons. However, the cross between MP14030A and MP15P038R (MP7878) showed irregularities in both seasons due to modifiers and environmental factors. These irregularities stemmed from an excess of fertile plants (FF) in the post-rainy season or an excess of sterile plants (FS) in the summer season. These observations provide valuable insights into the genetic dynamics of the A1 Cytoplasmic-Nuclear Male Sterility (CMS) system within commercial pearl millet hybrids. The study indicates that fertility restoration in the A1-based CMS system is strongly influenced by a single Dominant gene control mechanism governing the interplay between male sterility and fertility restoration in these crosses.

Authors: Kelly Noreen E. , Trela Olga , Gavel Heidi , Vander Kuylen Alyssa
Published: January 2024

Aim: To investigate the baseline abundance of microplastics on two sandy beaches along an exposed coastline in an understudied region of the Northwest Atlantic.

Methods: Sandy sediments were sampled from two beaches along the eastern shore of Nova Scotia, Canada from High, Mid, and Low intertidal positions. Density floatation using a sodium iodide (NaI) solution was used to separate particles from 100 g of sediments in each sample. Particles were characterized by size, shape, and colour, and Fourier transform infrared (FTIR) spectroscopy was conducted for polymer identification.

Results: At both beaches, the majority of particles found were small (< 1.4 mm), transparent microfibers. Microplastics were polymers of polyethylene terephthalate (PET), nylon, or alkyds (paints). The mean concentrations at both beaches were similar, at 5.08 ± 3.20 and 5.58 ± 4.52 microplastics per 100 g of sediment. Non-plastic (i.e., natural and semi-synthetic cellulosic) microfibers were up to 19 times more abundant than microplastics, with mean concentrations of 75.9 ± 60.1 and 97.7 ± 87.9 per 100 g sediment. Mean particle counts did not differ significantly across tidal ranges due to their high variability over small spatial scales (10 s of m).

Conclusion: Using new investigative tools yielded estimates of microplastic pollution 1-2 orders of magnitude lower than earlier research conducted at these sites, and was generally lower than values reported from other beaches globally. Sources of microfibers were potentially from high recreational use at these sites. Future monitoring could target these sites for time series analysis of microplastic change on exposed sandy beaches.

O objetivo foi analisar os entraves tecnológicos para a implementação de tecnologias limpas no processo de produção de carne bovina. Utilizou-se uma abordagem qualitativa e o procedimento do estudo de caso com unidades de análises incorporadas. Como instrumento de coleta de dados, empregou-se documentos, registros, arquivos, entrevistas com atores ligados diretamente a indústria de processamento de carne bovina, e vídeos das etapas de processamento do abate bovino. As principais tecnologias ambientais para redução de consumo energia nas indústrias frigoríficas ainda são incipientes no Brasil. Os resultados da pesquisa apontam que ainda há diversos entraves que impedem o uso de tecnologias ambientais na indústria de processamento de carne bovina. As principais dificuldades para investimentos em novas tecnologias para redução de consumo de energia é o alto custo dos impostos, além da falta de incentivos fiscais e alta taxa de importação, o que ocasiona altos custos. Muito embora, sejam vistas oportunidades promissoras para instalação de tecnologias limpas nos frigoríficos por meio de novos processos industriais e tecnologias ambientais. Diante disto, é possível afirmar que há um campo de investigação de novas tecnologias ambientais para a indústria de processamento de carne bovina.

Speaking is a crucial aspect when we learn English. However, speaking activities in class is a challenge for students from different educational backgrounds, such as those from remote areas in Bengkayang, West Kalimantan. This study aims to explore the speaking challenges of Bengkayang students in the Speaking for Social Purposes (SFSP) classes at the English Language Education Program, Universitas Kristen Satya Wacana (UKSW). To collect the data, this study used semi-structured interviews that involved seven students from Bengkayang who had taken SFSP classes. The data analysis indicated some challenges faced by the students, such as a lack of self-confidence, pronunciation errors, and lack of vocabulary. This research also hopes to provide practical tips and tricks for students in overcoming some English speaking difficulties in similar contexts. Recommendations for future research are also discussed.

Published: January 2024

The necessity for effective intrusion detection systems (IDS) in big data environments has grown critical due to the rising prevalence of big data systems and the rising amount of security threats. Applying conventional intrusion detection methods to the enormous and intricate data produced by big data ecosystems presents difficulties. Deep learning, has proven to be exceptionally adept at deciphering complex, large-scale data. This study proposes a Deep Learning-based Intrusion Detection System (IDS) created specifically for the Big Data environment. Traditional intrusion detection systems struggle to efficiently identify and prevent cyber threats due to the ever-increasing volume and complexity of data in current networks. We suggest an IDS that makes use of Deep Learning (CNN, LSTM, GAN, etc.), to address this problem. These cutting-edge neural network topologies give the system the ability to process and analyze massive amounts of data for precise intrusion detection. Data collection, data preprocessing, feature engineering, DL model training, intrusion detection, warning generation, and reaction are some of the crucial parts of the suggested IDS. The data collection module mines the Big Data environment for network traffic, system logs, and security event information. To make sure the data is suitable for analysis, it is preprocessed. To improve the detection abilities of the DL models, important features are extracted from the data using feature engineering approaches.

The purpose of this scoping review was to comprehensively clarify the methodology of Mental practice (MP) to date by systematically mapping studies that have performed MP on post-stroke paralytic upper extremity function. Specifically, (1) When is the most common timing of MP in-tervention after stroke onset? (2) What is the MP load (intervention time, number of interven-tion days, and intervention period)? (3) What are the most common methods of Motor Imagery (MI) recall and MI tasks during MP? (4) Is MP often used in conjunction with individual rehabili-tative therapies? (5) What is the paralyzed side's upper limb and cognitive function level at the start of MP intervention? Our scoping review was performed ac-cording to PRISMA-ScR to iden-tify research questions. Then, the PubMed, Scopus, Medline, and Cochrane Library databases were used to screen articles published by July 19, 2022. Eligible articles were selected all study designs were included, including studies involving the use of MP for post-stroke paralytic upper extremity function. Selection of eligible papers was done by two or more independent persons. Data were extracted from the eligible papers for items necessary to identify the research ques-tions. English-language articles identified for this study were 694, of which 62 were accepted. The most common intervention time was 30 minutes or less and the duration of the intervention was 5 times a week in MP. The most common method of recalling MI during MP was using an audio guide. In the future, it will be important to conduct accumulation of research to unify the varied widely MP methodologies identified in this study.

Authors: Sun Jianwei , Hou Shaoyun , Guo Yuehao , Cao Xinying , Zhang Dongdong , Zhang Peng
Published: January 2024

Steel slag and GBFS are wastes generated during the steel and iron smelting process, characterized by their considerable production rates and extensive storage capacities. After grinding, they are often used as supplementary cementitious materials. However, the intrinsic slow hydration kinetics of steel slag-GBFS cementitious material (SGM) when exposed to a pure water environment result in prolonged setting times and diminished early-age strength development. The incorporation of modifiers such as gypsum, clinker, or alkaline activators can effectively improve the various properties of SGM. This comprehensive review delves into existing research on the utilization of SGM, examining their hydration mechanisms, workability, setting time, mechanical strengths, durability, and shrinkage. Critical parameters including the performance of base materials (water-to-cement ratio, fineness, and composition) and modifiers (type, alkali content, and dosage) are scrutinized to understand their influence on the final properties of the cementitious materials. The improvement mechanisms of various modifiers on properties are discussed. This the promotes resource utilization of industrial solid wastes and provides theoretical and technical support for the application of SGM.

Published: January 2024

Pressure ulcers carry a significant risk in clinical practice and require effective preventive measures. This paper proposes a practical and interpretable approach to estimate the risk levels of pressure ulcers using decision tree models. In order to address the common problem of imbalanced learning in nursing classification datasets, various oversampling configurations are analyzed to improve data quality prior to modeling. The decision trees built are based on three easily identifiable and clinically relevant pressure ulcer risk indicators: mobility, activity and skin moisture. Their analysis allows nursing professionals to predict the risk levels of pressure ulcer and make informed decisions about patient care. Additionally, this research introduces a novel tabular visualization method to enhance the usability of the decision trees in clinical practice. The approach proposed aims to support nursing professionals in making timely decisions regarding the appropriate preventive interventions according to the risk levels of pressure ulcers, thus improving patient outcomes and healthcare costs. The usefulness and effectiveness of the models presented make them a valuable resource for nursing care in the prevention of pressure ulcers.
