Authors: Honcharenko Yevhenii , Gorda Olena , Semerikov Serhii
Published: February 2025

Improving the quality of the educational process and bringing it up to modern standards is a complex task that requires a systematic approach and the devel-opment of a strategy for improving the quality of service and efficiency. This work examines the specifics of information modeling within an ontological approach to distributed information environments, as well as the essence of ontological analysis of management business processes for the educational process in higher education institutions. An ontological analysis of modeling business processes in higher education institutions and an analysis of the structure, functions, and information flows of organizing and managing educational activities based on a structural approach are conducted. Competence, as an integrated characteristic of the graduate՚s quality, is considered a result of education. The use of an ontological model of interaction between subjects and objects of the system allows for the evaluation of the system՚s effective-ness and the construction of a management model, enabling the forecasting of critical business processes that may lead to a decrease in decision-making efficiency and disruptions in the functioning of higher education institutions and their units. The paper proposes a concept for the mathematical modeling of ontology and optimization of business processes in higher education institutions under conditions significant for their design. The structural model of the business process proposed in the paper includes both production and service components. The proposed models allow for mathematical modeling and optimization of business processes without constraints on their complexity, as well as the creation of software complexes based on them for numerical (non-descriptive) design of business processes.

The main objective of this work was to study the performance of thin-film composite (TFC) membranes developed for the treatment of saltwater. The synthesis of TFC polymer membranes was successfully achieved through interfacial polymerization between m-phenylenediamine (MPD) and trimesoyl chloride (TMC) on a 150 μm thick polyethersulfone (PES) support. The permeability and selectivity of the TFC membranes were investigated by incorporating cellulose acetate (CA) at various concentrations in an aqueous solution of MPD. The physicochemical properties of the prepared membranes were analyzed using FTIR, as well as in terms of water content and mass transfer characteristics. The optimized TFC membrane (TFC3; MPD: 2% by weight, CA: 5.7% by weight) exhibited improved efficiency in rejecting NaCl, CaCO3, and MgSO4, with respective rejection rates of 59.81%, 52.24%, and 62.53%, and a flux of 98 L/m².h. The flux recovery rate of this membrane was higher than that of the standard TFC membrane, indicating better resistance to fouling.

In this paper, hybrid composites were fabricated by incorporating coir fiber, glass fiber, and silicon carbide (SiC) into an epoxy resin matrix. The composites were developed to assess tensile, flexural, and impact properties, adhering to ASTM standards. Among the samples, the composite containing proportions of 20% coir and 20% glass fiber, along with 10% SiC, exhibited the highest tensile strength of approximately 100 MPa, flexural strength of 146 MPa, and impact strength of 85.4 kJ/m². Additionally, this sample demonstrated a water absorption rate of just 8%. Thermal gravimetric analysis revealed that composites with varying coir ratio, such as 10%, 20%, 30% and 40% coir reinforced with SiC, showed enhanced thermal stability, particularly due to the lignin present in coir fiber. The XRD and FTIR analyses confirmed the presence of coir, glass fiber, and SiC within the composites. These findings suggest that the proposed hybrid composites offer potential for applications in the building industry, such as exterior walls, indoor panels and floor tiles.

This review presents current advances and future perspectives for bioethanol production by fungal lignocellulosomes, based on studies conducted in the last few decades. The key steps for obtaining fermentable sugars for bioethanol production from lignocellulose are its pretreatment and enzymatic saccharification. Lignocellulosics are abundant and cost-effective sources as a potential “green” substitution for fossil fuels. Therefore, it is not surprising that the powerful fungal lignocellulolytic enzymes have been intensively studied, especially in terms of environmentally friendly economic and social development. The effects of fungal co-cultivation on the capacity of their lignocellulosomes are also discussed. As bioethanol production has not yet developed on a large scale, the future of this field lies in redesigning enzyme cocktails and reducing limitations in the conversion process. Lignocellulose is definitely a promising source for biofuel production, but on the way to its successful transformation are obstacles that will be overcome by future research.
Relationship between sound pressure distribution and drying effect for a wet cloth sample in an intense aerial standing wave sound field
Authors: Owada Chika , Asami Takuya , MIURA Hikaru
Published: February 2025

The authors have been studying the promotion of non-contact drying of wet cloth by forming a standing wave sound field in the air using intense aerial ultrasonic sources. In this paper, the sound pressure distribution with a wet cloth sample was examined, and the relationship between the sound field and the drying effect was investigated. When a high-water-content sample that was larger than the wavelength of the sound wave was placed at the sound pressure node, the standing wave sound field was changed by the reflection of the sound wave. However, the drying experiments showed that the drying effect was similar to that with the sample at the anti-node, demonstrating the usefulness of drying by ultrasonic waves.

Published: February 2025

Software Defect Prediction is crucial to ensure software quality. However, high-dimensional data presents significant challenges in predictive modelling, especially identifying the most relevant features to improve model performance. Therefore, efforts are needed to address these issues, and one is to apply feature selection methods. This study introduces a new approach by applying the Copeland ranking method, which aggregates feature weights from multi-wrapper methods, including Recursive Feature Elimination (RFE), Boruta, and Custom Grid Search, using 12 NASA MDP datasets. The study also applies Random Forest classification and evaluates the model using AUC and t-Test. In addition, this study also compares the accuracy and precision values produced by each method. The results consistently show that the Copeland ranking method produces superior results compared to other ranking methods. The average AUC value obtained from the Copeland ranking method is 0.7496, higher than the Majority ranking method with an average AUC of 0.7416 and the Optimal Rank ranking method with an average AUC of 0.7343. These findings confirm that applying the Copeland ranking method in wrapper-based feature selection can enhance classification performance in software defect prediction using Random Forest compared to other ranking methods. The strength of the Copeland method lies in its ability to integrate rankings from various feature selection approaches and identify relevant features. The findings of this research demonstrate the potential of the Copeland ranking method as a reliable tool for ranking features obtained from various wrapper-based feature selection techniques. The implementation of this approach contributes to improved software defect prediction and provides new insights for the development of ranking methods in the future

Published: February 2025

This study investigated supplementing dried rosemary leaves to the diet of some semen, as well as blood biochemical traits in Holstein bulls. The eight bulls were divided equally into two groups (4bull/group). Bulls' in the first group were fed a diet without additives (control group). The bulls in the second group were fed a diet supplemented with 250mg rosemary per bull daily for 12 weeks, preceded by a two-week preliminary period. We detected some of the rosemary's active components. The semen was collected and evaluated weekly for 12 weeks. The serum concentrations of glucose, urea, aspartate, and alanine transaminase were determined. The active components analysis of rosemary revealed it contains phenolics (Gallic acid), flavonoids (Luteolin, Quercetin, Rutin, Kaempferol, Tannic acid, and Epicatechine), saponins, and vitamins (A, E, and C). The results revealed higher (P≤0.05) mass activity, motility, live sperm, and normal morphology of sperms in the rosemary group than in the control group. The rosemary group recorded a lower (P≤0.05) semen volume, head sperm and total abnormalities, glucose, and urea than the control group. In conclusion, the active components, especially flavonoids and phenolics in rosemary, may improve insulin sensitivity by testis to take glucose, which somewhat ameliorates the semen quality of Holstein bulls and overcomes some climate change influences on sustainable consumption and production.

THE USE OF BIOMARKERS IN PHYSIOTHERAPY FOR PERSONALIZED MEDICINE
Authors: Mathur Nikhil , Mathur Suhani
Published: February 2025

The integration of biomarkers into physiotherapy represents a groundbreaking shift towards personalized medicine,
offering enhanced precision in treatment strategies. Traditionally reliant on clinical assessments and generalized
protocols, physiotherapy is evolving with the advent of biomarkers—measurable indicators of biological processes,
disease states, or therapeutic responses. This article explores the types of biomarkers relevant to physiotherapy,
including inflammatory markers, muscle damage markers, oxidative stress markers, metabolic biomarkers, genetic
biomarkers, and physical performance metrics. Their applications in diagnosis, prognosis, treatment response
monitoring, rehabilitation progress, and risk stratification underscore their transformative potential. By tailoring
rehabilitation programs to individual patient profiles,biomarkers enable physiotherapists to optimize recovery, reduce
complications, and improve overall outcomes. Despite challenges such as standardization, ethical considerations, and
technological demands, the future of biomarker-driven physiotherapy is promising, fostering interdisciplinary
collaboration and advancing precision medicine. This paradigm shift paves the way for innovative, patient-centered
care in rehabilitation,enhancing quality of life and treatment efficacy.

Introduction: Lead (Pb) is a hazardous metal that presents substantial health hazards to both humans and animals. Extended exposure to lead can result from various causes, such as contaminated water, soil, and industrial emissions, causing nephrotoxicity and kidney damage. Methods: This study investigated the long-lasting impact of lead acetate on the kidneys of Wistar rats. The rats were categorized into four distinct experimental groups, consisting of one control group and three treatment groups. The treatment groups were exposed to varying amounts of lead acetate (2.5%, 3.0%, and 3.5%). The rats had a 35-day treatment period during which their weights was closely monitored, and after sacrificing, kidney function, and histological alterations were assayed. Findings: The data revealed a significant increase in weight among the groups receiving therapy, which can be attributed to the accumulation of water and edema. The 2.5% lead acetate treatment group exhibited higher creatinine levels, suggesting kidney damage. The histological examination showed evidence of kidney injury, including glomerular lesions, fibrotic lesions, and the buildup of leukocytes. Conclusion: Lead acetate induces nephrotoxicity and weight gain in Wistar rats, resulting in a substantial effect on both kidney function and structure. The study emphasizes the significance of taking into account several biomarkers and histological observations in order to comprehend the effects of toxic chemicals such as lead acetate. The results indicate that exposure to lead acetate can result in the development of chronic kidney disease, highlighting the importance of appropriately managing and disposing of items that contain lead.

Published: February 2025

Background: Humeral shaft fractures (HSFs) represent 3% of the fractures of the locomotor apparatus, and the middle third of the shaft is the section most affected. In the majority of cases, it is treated using nonsurgical methods, but surgical indications in HSF cases are increasingly being adopted. They are most common in males between 21 and 30 years old and females between 60 and 80 years old. Objective: To compare the intramedullary nailing and plate fixation in adult humeral shaft fractures. Materials and Methods: This was a prospective comparative study carried out in the Department of Orthopedics, Jahurul Islam Medical College & Hospital, Bhagolpur, Bajitpur, Kishoregonj for 2 years based on the patient presentation at both emergency room and outpatient clinic department between June 2021 and March 2023 in which fifty adult patients with humeral shaft non-union were recruited. Coagulopathies, on drugs like steroids, anti-neoplastic that may interfere with healing and those with significant co-morbidities such as Diabetes Mellitus, Neoplasia were all excluded from the study. Results: The nailing group operated for 84.11±8.98 minutes, while the plating group took 115.66 ± 9.56 minutes. The result was statistically significant (P < 0.05). The nailing group lost 75.02 ± 9.57 mL of blood during surgery, significantly less than the plating group's 132.79 ± 8.64 mL (P < 0.05). Of the 25 patients in the plating group, nine (36%) had outstanding results and eight (32%) had good results. In the nailing group, 11 (44%) achieved great outcomes, and 9 (36%) had good results. The two groups did not differ statistically from one another. Conclusion: The nailing group required less operating time and had less blood loss than the plating group. There were no significant differences in functional outcomes between the intramedullary nailing and plating groups.

Authors:   Ufa Scientific Research Center of the Russian Academy of Sciences, ISMAGILOV K.R.
Published: February 2025

The article presents an analysis of the nature and degree of influence of the main agro-climatic resources on the formation of the sugar beet harvest in the Republic of Bashkortostan. It is shown that in recent years, the yield of sugar beet in the Republic of Bashkortostan has been increasing naturally and its annual increase is 9.549 kg/ha. The dependence of the yield variance relative to the trend has a curved shape in the form of a parabola. With the amount of precipitation ranging 200-364 mm during the growing season, the yield is formed above the trend and reaches its maximum value with the amount of precipitation of 282 mm. In general, the increase in thermal resources has a negative effect on the formation of the sugar beet harvest. The sum of temperatures during the growing season (above 10°C) ranging 2400-2600 °C is optimal for the formation of sugar beet yields in the Republic of Bashkortostan. The dependence of yield on the hydrothermal coefficient has the form of a single-vertex curve ( = 0.678), with the value of this indicator ranging from 0.77 to 1.46, the yield of sugar beet increases, and the top increase is achieved with the value of the hydrothermal coefficient equal to 1.11.

However, this practice may lead to physical, psychological, and social harm to patients, thereby raising ethical dilemmas. This study aims to explore the ethical challenges encountered by nurses in surgical intensive care units concerning the application of physical restraints.
Material and Methods: A descriptive and correlational research design was employed. Data analysis involved descriptive statistical methods, including frequency, percentage, minimum-maximum values, median, mean, and standard deviation. The Shapiro-Wilk test was utilised to assess data normality. All statistical tests were conducted with a 95% confidence interval and a significance level of 0.05.
Results: The study included 80 nurses, with data collected through face-to-face interviews. Of these, 71.3% reported having used physical restraints, while 55% indicated they had not received ethical training on the subject. Significant differences were observed in physical restraint practices relative to gender, age, unit of employment, and weekly working hours (p < 0.05). Furthermore, an examination of nurses' ethical values and demographic characteristics revealed a significantly higher desire for training on physical restraint within the study group.
Conclusion: The findings highlight that nurses face ethical dilemmas in the use of physical restraints and underscore the necessity for ethical education. An increase in nurses' awareness of ethical values was directly proportional to their participation in ethical training. These results emphasise the critical importance of ethical education in surgical intensive care units.

Rheumatic fever is an inflammatory disease that can damage the heart valves, in some cases requiring surgical replacement to restore heart function. However, this intervention is not without its complications. This article reviews the main surgical complications in patients undergoing heart valve replacement due to rheumatic fever. The narrative review included nine articles published between 2016 and 2023, selected from databases such as Google Scholar and VHL. Strict inclusion criteria were applied and the results analyzed were systematized in a database. The findings indicate that patients with rheumatic fever are at greater risk of complications after valve replacement. Infective endocarditis is one of the most frequent complications and can cause heart failure and serious embolisms. In addition, the formation of clots in the replaced valves can lead to strokes and other ischemic complications. Residual valve insufficiency, characterized by the inadequate functioning of the new valve, has also been observed, generating inefficient blood flow and symptoms of heart failure. Arrhythmias are another common complication, aggravated by the increased risk in patients with rheumatic fever. The risk of surgical site infections is significant due to the chronic inflammatory nature of the disease, increasing vulnerability to problems such as endocarditis. Prevention and proper management of complications are essential. Careful patient selection, the use of prophylactic antibiotics and post-operative follow-up play a fundamental role in reducing the risks. In addition, controlling inflammation and preventing recurrences of rheumatic fever are crucial in the long term. Patients with rheumatic fever face significant challenges after heart valve replacement, making strategies for early identification and efficient management of complications essential. Collaboration between specialists is essential to promote better outcomes and improve the quality of life of these patients.

A internação de um recém-nascido na Unidade de Terapia Intensiva Neonatal (UTIN) é um evento que gera grande impacto emocional nos pais, podendo comprometer o estabelecimento do vínculo afetivo. O contato precoce e contínuo entre pais e bebê é essencial para o desenvolvimento emocional e fisiológico do recém-nascido, além de contribuir para a redução do estresse parental. Diante disso, este estudo tem como objetivo analisar a importância do vínculo entre pais e recém-nascidos internados na UTIN, destacando os benefícios desse contato para ambos e as estratégias que podem ser adotadas pela equipe de saúde para fortalecer essa relação. Os resultados indicam que a promoção do vínculo parental na UTIN está associada a benefícios como a estabilização fisiológica do bebê, melhora no ganho de peso e no tempo de recuperação, além da redução dos níveis de ansiedade e depressão nos pais. O método canguru, por exemplo, é uma das principais estratégias utilizadas para fortalecer essa relação, permitindo o contato pele a pele e incentivando a participação ativa dos pais no cuidado do recém-nascido. A presença dos pais na UTIN, aliada ao apoio psicológico e informacional oferecido pela equipe de enfermagem, favorece a construção de um ambiente humanizado e acolhedor, reduzindo a sensação de impotência e medo que pode acompanhar essa experiência. A discussão aponta que, apesar dos benefícios comprovados do vínculo precoce, ainda existem barreiras que dificultam sua implementação, como normas hospitalares restritivas, falta de capacitação dos profissionais para lidar com as demandas emocionais dos pais e a sobrecarga da equipe de saúde. A humanização do cuidado neonatal é fundamental para garantir que os pais se sintam inseridos no processo de recuperação do bebê, fortalecendo o vínculo familiar e promovendo o bem-estar de todos os envolvidos. Conclui-se que o vínculo entre pais e recém-nascidos na UTIN é essencial para o desenvolvimento da criança e para o equilíbrio emocional dos pais. A equipe de saúde tem um papel fundamental nesse processo, devendo adotar práticas que favoreçam a aproximação familiar e garantam um cuidado humanizado. O fortalecimento desse vínculo não apenas melhora os desfechos clínicos dos recém-nascidos, mas também contribui para uma experiência hospitalar menos traumática para a família, reforçando a importância de políticas que incentivem a participação ativa dos pais no cuidado neonatal.

Authors: Włodarczyk Bartłomiej
Published: February 2025

Teza/cel artykułu – Celem artykułu jest scharakteryzowanie i po- równanie treści postów zamieszczonych przez wybrane chińskie biblioteki akade- mickie (Bibliotekę Uniwersytetu Wuhan – BUW, Bibliotekę Uniwersytetu Qing- hua – BUQ oraz Bibliotekę Uniwersytetu Nauki i Technologii Chin – BUNTC) na platformie WeChat. Skupiono się na treściach dotyczących infrastruktury, usług, wydarzeń, zasobów informacyjnych i oprogramowania. Metody badań – W artykule wykorzystano metodę analizy treści oraz porównawczą. Materiał empiryczny do badania stanowiło 450 wpisów opublikowanych przez wybrane biblioteki akademickie na kontach publicznych WeChat w semestrze wiosennym 2022 r. Zostały one pobrane do programu Zotero, a następnie przeanalizowane pod kątem ilościowym i jakościowym. Wyniki i wnioski – Wpisy zamieszczone przez poszczególne biblioteki różnią się pod względem liczebności i regularności ukazywania się. Najbardziej regularnie publikowała swoje wpisy BUW zamiesz- czając dziennie od jednego do dwóch wpisów. Większe zróżnicowanie widoczne jest w przypadku pozostałych instytucji, z których BUQ robiła to najmniej syste- matycznie publikując dziennie nawet sześć postów. Różnice występują również w zakresie tematyki postów. Ogólny układ treści postów jest podobny w BUQ i BUNTC (największy odsetek postów w kategorii Zasoby informacyjne i opro- gramowanie, potem w kategorii Wydarzenia, Usługi i Infrastruktura). Od tego schematu odbiegają posty BUW, które częściej dotyczyły wydarzeń niż zasobów informacyjnych. Różnice widoczne są również w ramach kategorii, w których kładziono nacisk na inne elementy. Wynikały one z charakteru i specjalizacji kon- kretnej biblioteki oraz sytuacji epidemicznej.
