Authors: Pandey Apsara , Dhungel Rejina
Published: February 2025

Background: Stress is a major contributing factor to many psychological illnesses that plague today’s society. A student’s life is impacted by a variety of stressors, including academic pressure with the expectation of success, fear of anticipated academic failure, and an uncertain future. The objective of the study was to determine the level of academic stress among undergraduate nursing and midwifery students.
Methods: A descriptive cross-sectional study was conducted among 157 undergraduate nursing and midwifery students at Tribhuvan University (TU) in Kathmandu, Nepal. Different years of various bachelor level programs were taken as strata and proportionate stratified probability sampling technique was used to select the required sample for the study. The instrument included sociodemographic and academic characterization questions, as well as a self-administered, structured Scale for Assessing Academic Stress (SAAS) to collect data. Frequencies, percentages, means, standard deviations, and Pearson’s chi-square or Fishers exact test were used to analyze the data.
Results: The mean age of the students was 23.08 years, with 98.7% being female and 85.4% unmarried. More than half (63.7%) of the students reported low academic stress, while 36.3% reported high academic stress. The study also revealed that stress related to cognitive indicators was higher (mean ± SD = 3.17 ± 1.91) compared to affective indicators, (mean ± SD = 1.43 ± 1.49). Academic stress among students was found to be significantly associated with their age (p = 0.004) and academic year (p = 0.026).
Conclusions: Nursing and midwifery students experience academic stress, which is associated with age and academic year. Stress reduction activities such as meditation, yoga, and other recreational activities might be helpful to the students.

Introduction: Menopause is one of the most significant stages in the female reproductive life cycle. It brings several physiological and psychological changes that affect women's lives, with 75% of women experiencing menopausal symptoms in some form. The objective of the study was to assess the Frequency and Severity of Menopausal Symptoms among Middle-Aged Women residing in Pokhara Metropolitan City.
Methods: A descriptive cross-sectional study was conducted among 236 respondents aged 45-60 years. Simple random sampling technique was adopted for selecting the wards. A simple random sampling technique using the lottery method was used to select three wards. Data was collected from the eligible respondents from those households of the selected wards on first come first basis by visiting house to house. Data was collected by using a validated tool i.e Menopause Rating Scale (MRS). Data was collected from 16 December 2021 to 13 February 2022. The collected data was coded into the statistical package for Social Science (SPSS) version 16 and analyzed by using descriptive and inferential statistics to measure the frequency of the symptoms and assess the severity of the symptoms respectively.
Results: Findings revealed that almost all (96.6%) of respondents had at least one menopausal symptom. The most prevalent menopausal symptom was joint and muscular discomfort (75.8%) followed by irritability (73.3%) and physical and mental exhaustion (72.4%). Regarding the severity of the symptoms, joint and muscular discomfort symptoms were reported as very severe (2.1%) the most. Likewise, in the sub-domain of menopausal symptoms a higher mean score (4.24±2.91) was found in the psychological domain.
Conclusions: This study concludes that the majority of women experience joint and muscular discomfort as well as irritability during menopause. Therefore, healthcare providers should provide education on the management of physical and psychological symptoms and promote routine screening to facilitate the early identification and management of menopausal symptoms.

Authors: Subedi Arjun , Kafle Prakash
Published: February 2025

Hemorrhagic strokes typically occur unilaterally, often in individuals with a history of hypertension. Bilateral recurrent hemorrhagic strokes are exceedingly rare and present significant clinical challenges in patient management. This case report discusses a patient with recurrent hemorrhagic strokes in the bilateral basal ganglia, detailing the clinical course and management strategies. A 58-year-old male with a five-year history of hypertension presented with complaints of a headache lasting three days and generalized weakness accompanied by difficulty walking due to right-sided hemiparesis. Imaging revealed a left basal ganglia bleed. Within a year, he experienced a similar episode with left-sided hemiplegia, and imaging confirmed a new hemorrhage in the right basal ganglia. Recurrent hemorrhagic stroke underscores the necessity for effective blood pressure control through antihypertensive medications and lifestyle modifications, as well as vigilant patient monitoring to mitigate the future risk of such events, ensuring long-term prognosis and quality of life. In brief, this study examines a particular medical case involving recurrent hemorrhagic strokes in both sides of the brain's basal ganglia. It provides a thorough analysis of the sequence of these hemorrhagic events, detailing their characteristics and exploring the possible underlying causes and treatment strategies.

Authors: Santos Vinícius Ramos Israel , Scinocca Francisco , Almeida Luis Gustavo Nunes de , Santos Fábio Lúcio
Published: February 2025

In recent years, research and development in the automotive industry have increasingly focused on safety, comfort, and energy efficiency. A crucial area of this research is the wheel/tire system, which is vital in ensuring vehicle safety and drivability. This study examines the effects of various types of loads applied to the wheel/tire system. Furthermore, it assesses the safety factor and potential fatigue-related failures in automotive wheels, identifying the areas with significant deformations and displacements. The research employs CAD and CAE software to analyze the behavior of automotive wheels, utilizing the Finite Element Method (FEM), which is commonly used during the automotive design phase to reduce costs associated with prototypes and validation. In the modal analysis, we examined the first four vibration modes, with the natural frequencies and modal shapes ranging from 350 to 610 Hz. For vertical impact analysis, we applied an internal tire pressure of 200 kPa (29 psi) along with a force of 9 kN to the tire, keeping the wheel fixed and the screws secured. This analysis revealed a safety factor of 2.60 for the most critical case. In the lateral fatigue analysis, a force of 1.5 kN was applied to the region around the screws using a 760 mm lever arm. This scenario resulted in a safety factor of 2.66. Lastly, for the radial fatigue analysis, we maintained an internal tire pressure of 200 kPa (29 psi) and applied a force of 7.5 kN to the screw region, simulating the tightening torque. The safety factor for this most critical case was determined to be 1.76.

Authors: Brian O. Ogbonna
Published: February 2025

Psychoactive substances could be used for medical and non-medical reasons, but need to be used with caution in pregnancy due to their negative effects on the fetus. Globally and in Nigeria, there are limited studies conducted on the use of, and effects of psychoactive substances by pregnant women probably due to the special population required despite the wide range of psychoactive substances readily available and easily accessible by pregnant women. This study examined the dynamics of psychoactive substance use in pregnancy in Nigeria, the effects on pregnancy and neonates, and critical methods of regulation, intervention, and prevention. The study utilized a narrative review to assess the dynamics in the prevalence, use, and effects of psychoactive substances by pregnant women. The study was synthesized from several research articles assessed through electronic means. Search terms were used either individually, in series, or using truncation where necessary. Studies considered were those conducted in Nigeria and published in the English Language from January 1970 to December 2023. All of the articles fell below the 3rd position on the 8points Oxford Center for Evidence-Based Medicine Scale (OCEMS). Overall, 11 articles were selected from a total of 1260 articles which gave rise to 0.87% selection eligibility criteria. The southwest had the highest distribution of studies on psychoactive substance use in pregnancy 6.0(54.5%), followed by south east 2.0(18.2%) and north central at 1.0(9.1%), and south at 1.0 (0.9%). Studies hierarchy fell in the fourth stage of the 6 points Scottish Intercollegiate Guideline Network Scale (SIGNS) for the hierarchy of study types. Psychoactive substance uses in pregnancy in Nigeria fell at the lower half of two standard benchmarks for study types. Most of the studies were predominantly carried out in the southern part of Nigeria. Systematic reviews and meta-analyses, Randomized Controlled Trials, Nonrandomized intervention studies, experiment studies, and Expert opinions on psychoactive substance use in pregnancy in Nigeria were still not available in the country.

Authors: Kenea Madessa Kidist
Published: February 2025

Background: Hypertension is a major global issue, with high morbidity and mortality rates. It is estimated to be 6% in Ethiopia and 30% in Addis Ababa. Adherence is the degree to which a person's medication-taking behaviour corresponds to the health care provider's medical advice. It encompasses both dosage frequency and timing of ingestion. Poor adherence is connected with poor illness outcomes and a waste of healthcare expenditures.

Objective: To assess the extent of Adherence to antihypertensive medications and the reasons for non-adherence among hypertensive patients.

Methodology: An institution-based cross-sectional study was conducted at Yekatit12 Hospital Medical College using structured questionnaires from February to May 2022 G.C. The collected data was processed and analyzed using computer software using SPSS version 21.0, presented in tables and figures and then interpreted based on the findings.

Greenwashing and reputational risks in the hotel industry
Authors: BOVSH Liudmyla , RASULOVA Alla
Published: February 2025

To determine the development strategy, econo­mic entities should take into account global trends in society and business.  Therefore, the focus on sustainable development, environmental protect­tion and adherence to the principles of environ­mental responsibility are relevant issues for creating and strengthening reputational capital nowadays. Behavioral patterns of consumers and stakeholders demonstrate an advantage in relati­ons with hotels that implement a transparent policy of green entrepreneurship, support environmental and social initiatives. Visualization of false envi­ronmental declarations can lead to loss of loyalty, a decrease in the reputation of the hotel business entity, as well as a loss of trust in environmental initiatives in general. However, the lack of transparent criteria for assessing environmental friendliness and the spread of greenwashing significantly complicate the identification of such hotels. The main hypothesis is that the use of greenwashing is a short-term strategy that provides temporary consumer loyalty, but in the long term leads to a loss of customer trust, a deterioration in the reputation of the hotel brand and a decrease in its competitiveness. The research is based on the use of theoretical methods (analysis, synthesis, systematization, historical-logical, content analysis), empirical research (sur­veys, case studies), as well as modeling and benchmarking.
The concept of greenwashing, its main types and mechanisms of use in the marketing strategies of hotel business entities are considered. The im­pact of false environmental claims on the forma­tion of customer trust, competitiveness and long-term reputation of hotels is studied. Practical recom­mendations are proposed for identifying and combating the use of greenwashing through environmental audits, the introduction of trans­parent environmental standards and increasing business responsibility. The results of this research form practical recommendations for hotel mana­gement on how to avoid greenwashing and move towards real environmental initiatives

Um dos menores canídeos que ocorre no Brasil é o cachorro vinagre (Speothos venaticus), uma espécie com ampla distribuição na região Neotropical. Apesar dessa ampla distribuição, sua ecologia permanece pouco compreendida. A espécie está listada como quase ameaçada internacionalmente e foi recentemente reclassificada como vulnerável no Brasil. Neste estudo, registramos em momentos diferentes dois possíveis grupos de S. venaticus em uma área protegida no estado de Mato Grosso, dentro do domínio do Cerrado. Os registros foram obtidos através de armadilhas fotográficas instaladas no Parque Sesc Serra Azul, no município de Rosário Oeste. Esses destacam a importância da área para a espécie, fornecendo dados valiosos sobre sua distribuição e ecologia por meio de amostragem não invasiva. Além disso, registros raros como este reforçam a importância de criar e manter áreas de conservação para proteger espécies menos conhecidas, como o cachorro-vinagre, que enfrenta uma ameaça alarmante à sua sobrevivência .

Published: February 2025

Прогнозування фінансових ринків давно стало однією з найважливіших задач для інвесторів та трейдерів. Динамічність та складність ринків, численні фактори впливу, такі як економічні новини, геополітичні події та поведінкові аспекти учасників ринку, роблять цю сферу надзвичайно складною для аналізу за допомогою традиційних методів. З появою технологій штучного інтелекту, а саме нейронних мереж, з'явилася можливість ефективніше аналізувати великі обсяги даних і знаходити приховані закономірності, які неможливо виявити іншими способами.
Нейронні мережі стали однією з ключових технологій у сучасному фінансовому аналізі завдяки їхній здатності обробляти нелінійні залежності та працювати з великими наборами даних. Ці моделі імітують роботу людського мозку, що дозволяє їм виявляти навіть найскладніші взаємозв'язки у фінансових часових рядах, таких як зміни цін активів, коливання валютних курсів чи аналіз ринкових ризиків. Завдяки гнучкості, адаптивності та можливості самооптимізації, нейронні мережі стали надійним інструментом для передбачення ринкових трендів.
У цій статті розглянуто, як нейронні мережі застосовуються для прогнозування фінансових ринків, які типи архітектур найбільш ефективні для фінансового аналізу, та з якими викликами стикаються дослідники та практики під час їх впровадження. Нейронні мережі подано як основу для розроблення інформаційних технологій прогнозування фінансових ринків.

Currently, the main sources of alternating current electrical energy on airplanes and helicopters are contactless synchronous generators of the ГТ type with an alternating current exciter and rotating rectifiers.
When conducting research on power generation systems, for example, in order to implement a diagnostic method based on monitoring electrical parameters with subsequent special analysis of the received signal, it is necessary to have reference parameters (voltages, currents, transient characteristics, voltage and current spectra) of the machine. These parameters can be obtained experimentally or by modeling, because the machine parameters in the event of typical failures cannot always be obtained experimentally. This circumstance is associated with the complexity or impossibility of physically simulating failures. For this purpose, various types of application software packages are used (for example, Matlab/Simulink, LabVIEW/Control Design and Simulation), which allow modeling complex dynamic systems, including those described by nonlinear differential equations.
For example, synchronous generator models from the SimPowerSystems section of the Matlab/Simulink environment allow for good results in modeling normal generator operation. At the same time, standard models have limited failure simulation capabilities, allowing only open circuits and short circuits of windings to be simulated. To simulate other electrical and mechanical faults, standard models are usually upgraded or special ones are developed to simulate typical failures, in particular: stator winding or insulation failure, rotor winding or insulation failure, bearing failure, rotor mechanical integrity failure, stator mechanical integrity failure. As a review of publications has shown, no attention is paid to failures of the electronic part of cascade generators.
The proposed work presents a virtual model of a synchronous generator, built in the MatLab/Simulink simulation environment. The model is built taking into account the design features of cascade synchronous generators of the ГТ series: the presence of three generators in the machine - a magnetoelectric exciter, an electromagnetic exciter, an electromagnetic main generator; an uncontrolled three-phase rotating rectifier; a phase-pulse voltage regulator with a controlled rectifier. The proposed model allows you to study the operation of the generator in normal operation and in the event of typical generator failures, including electronic elements.
This model can be useful in studying the processes occurring in AC generation systems with ГТ series generators both in normal operation and in the event of failures. Therefore, the development of this virtual model in the Matlab/Simulink environment of a contactless synchronous generator allows you to obtain both reference parameters and parameters in the event of failures

The article examines key aspects of the development of the logistics potential of water transport in Ukraine in the context of modern geo-economic changes caused by military aggression, restructuring of global supply chains and increasing environmental requirements. The main challenges of the industry are identified, including the destruction of port infrastructure, blockade of seaports, change of trade routes, increasing transportation costs due to the energy crisis and the complication of customs procedures due to sanctions. Particular attention is paid to the negative impact of these factors on the functioning of the transport and logistics system and the country's export potential. The prospects for the modernization of water transport through the introduction of innovative technologies, digital transformation of logistics processes and the transition to environmentally friendly solutions are analyzed. The feasibility of developing multimodal transportation, automation of port operations and integration of Ukraine into global logistics networks is considered. The study emphasizes the need to create a modern roadmap for the development of water transport, which includes investments in port infrastructure modernization, dredging, stimulation of public-private partnerships and implementation of international environmental standards. The importance of international cooperation in the restoration and development of the industry is emphasized, including attracting international technical assistance, creating joint investment projects and integration into European transport corridors. State support should play a key role in creating favorable conditions for investment, introducing incentives for digitalization of processes and forming a regulatory framework that will contribute to the harmonization of transport policy with international standards. Strategic directions for the development of water transport in Ukraine are proposed, aimed at restoring the economic potential of the industry, its sustainable development and ensuring the competitiveness of Ukrainian goods in international markets. The introduction of innovations, compliance with environmental requirements and active international cooperation will contribute to the country's economic growth, its integration into global logistics systems and the formation of a modern transport infrastructure.

Published: February 2025

The use of liquid organic fertilizers (BIOLES) from agroecology is a practice used in small associations of farmers, rescuing ancestral knowledge around the care of the ecosystem and management of crops. This research evaluates the influence of two types of BIOLES on the production of maize (Zea mays L); the first with donkey dung and the second with llamas (T1; T2). Among the results, a similarity of means in the growth variables for the three study groups (T0; control plot, T1 and T2) stands out, with the first being the one with the best results, contrary to the behavior of the productive performance variables where T2 was the most relevant and presented a significant difference (Tukey p < 0.05) compared to the T0 group. It is concluded that BIOLES, especially T2, positively influences the productive yield of corn cultivation from an agroecological management.

Published: February 2025

High energy consumption is a global issue nowadays. The building sector consumes a tremendous amount of energy. Inspiration from nature (biomimicry) could be the driving force in architecture to achieve a high level of sustainability by translating biosystems into architecture. Drawing inspiration from various sources to address the challenge of the design problem, integrating the behaviour of biosystems into the building envelope could significantly influence energy performance. This paper investigates a bio-mimicry-based approach to enhancing energy efficiency in office buildings by analysing and comparing 8 projects in different climates. The result showed that the behaviour level is more applicable and functional than the organism. And ecosystem levels. Finally, the conceptual model would propose office buildings based on biomimicry strategies.

Community detection in network analysis has become more intricate due to the recent hike in social networks(Cai et al., 2024). This paper suggests a new approach named ELPMeans that strives to address this challenge. For community detection in the whole network, ELPMeans combines Laplacian, Hierarchical Clustering as well as K-means algorithms. Our technique employs Laplacian centrality and minimum distance metrics for central node identification while k-means learning is used for efficient convergence to final community structure. Remarkably, ELPMeans is an unsupervised method which is not only simple to implement but also effectively tackles common problems such as random initialization of central nodes, or finding of number of communities (K). Experimental results show that our algorithm improves accuracy and reduces time complexity considerably outperforming recent approaches on real world networks. Moreover, our approach has a wide applicability range in various community detection tasks even with non-convex shapes and no prior knowledge about the number of communities present.

Psoriasis remains a significant challenge in modern dermatology, necessitating the development of new effective treatments. For over a century, Naftalan-based medicinal products have been utilized in the treatment of inflammatory skin diseases. Considering the known limitations and the therapeutic potential of refined Naftalan oil (RNO), new topical pharmaceutical forms – dermatological creams – were developed and investigated.
The aim of the work – to evaluate the efficacy of new test samples (TS) of creams containing refined Naftalan oil in mono-formulation and in combination with drotaverine compared to a topical corticosteroid, hydrocortisone, on an experimental model of psoriatic skin lesions in mice.
This study presents the pharmacological evaluation of new TS creams on a model of imiquimod-induced psoriasiform skin lesions in BALB/c mice, induced through a 9-day topical application of IMQ. The creams under investigation included: 10% RNO; 10% RNO combined with 2% drotaverine; and 10% vaseline oil combined with 2% drotaverine. Their efficacy was compared to a reference preparation – a cream containing 1% hydrocortisone butyrate. Therapeutic efficacy was assessed using the modified PASI index on days 7, 14, and 21 of treatment.
The pharmacological study results demonstrated that the TS containing 10% RNO combined with 2% drotaverine showed the highest therapeutic efficacy among the tested creams. On day 21 of treatment, the modified PASI index was Me (25%–75%) = 2.0 (1.0–3.0), whereas the TS with vaseline oil combined with drotaverine exhibited moderate efficacy, outperforming the monocomponent cream with 10% RNO. The TS with 10% RNO combined with 2% drotaverine showed efficacy comparable to the reference preparation – a cream with hydrocortisone butyrate.
The obtained data highlight the potential for further in-depth pharmacological studies of TS with 10% RNO combined with the phosphodiesterase type IV inhibitor, drotaverine, to investigate its pharmacodynamics. The combination of these active pharmaceutical ingredients in this cream may provide a synergistic effect, leading to more effective reduction of inflammation and skin restoration in experimental psoriasis.

Bacterial cellulose (BC) is a promising polymer due to its ability to manage wound exudation and create a moist environment conducive to healing, alongside its high tensile strength. The natural form of BC hydrogel prevents it from maintaining its shape; therefore, water needs to be removed. The preparation of BC for wound dressing use often involves a drying process, which can significantly impact the final material’s properties. This article investigates the effects of drying methods on BC films, revealing structural changes in the membrane. Four different methods are selected, with methodical research on how drying affects physiological, morphological, and structural properties. The impact of each drying method on the physical, mechanical, and water-handling characteristics of BC is evaluated, providing insights into the optimal drying approach for achieving desirable wound dressing performance. The Oven Drying Method (ODM) alters BC’s structure, while the Freeze Drying Method (FDM) and Room Temperature Drying Method (RTDM) better preserve its morphology and mechanical integrity. Comparative analysis shows that ODM reduces elongation at break, whereas the Cold Drying Method (CDM) exhibits the highest elongation, indicating its suitability for wound dressings that require tensile strength within 1 to 32 MPa and a deformation capacity over 30%. As a result, CDM is appropriate for the preparation of BC films for use as wound dressings.

The article examines the obstacles faced by women in Turkiye who pursuit of political involvement and leadership. It sheds light on the problems that still exist today despite the fact that Turkiye has made great positive changes regarding women's rights and gender equality. These obstacles are categorized into structural, institutional, and cultural obstacles. Each category is explored in depth, revealing how these barriers collectively impede women’s full participation in political life. Understanding these barriers is critical for several reasons. First, equitable political representation is the cornerstone of democratic governance, and removing barriers to women’s participation is essential to ensuring that diverse perspectives are included in decision-making processes. Second, persistent inequalities in political representation can reinforce broader gender biases, impacting women’s opportunities and influence across sectors. Furthermore, addressing these challenges can help build a more inclusive and representative political system, which is crucial for the legitimacy and effectiveness of democratic institutions. By highlighting these obstacles, the article underscores the need for continued efforts to address gender inequality in Turkish politics. The findings contribute to a broader understanding of the challenges women face in political life and provide insights into possible ways to achieve greater women’s participation in political representation.

The rapid growth of immigrant communities and their institutionalization forced people to talk about the "diasporization of the world" as one of the scenarios for the development of mankind. One way or another, this process is deepening and taking more and more new forms, while the role of diasporas and their influence on society is growing stronger. The discussion that has unfolded in the scientific community shows how many blank spots and questions remain in the study of this changing phenomenon and how great are the differences between researchers in understanding it.

Today we are witnessing an increase in migration processes in the world, this process is accompanied by close interaction of immigrant ethnic communities. This situation is natural, since immigrants, having resettled, strive to be united, in the first years they are faced with the task, as a rule, of uniting in order not only to survive, but also to preserve their customs, traditions, and language. The above process forces them to join existing diasporas or create new ones. Every year the number of diasporas in the world is continuously increasing.

It is an undeniable fact that diasporas have a significant impact on states. They influence the demographic structure, ethnic and confessional composition of the country. Diasporas not only preserve their traditions, customs, rituals, but often impose alien values on society.

In the article, the authors not only analyze international experience in studying the role and significance of the diaspora, but also its influence on the development of the diaspora policy of Kazakhstan. Thus, in the Republic of Kazakhstan, the Concept of the Foreign Policy of the Republic of Kazakhstan for 2020-2030 was adopted, which defines the goals and objectives for supporting the Kazakh diaspora and the Kazakh language abroad and signed a law on the regulation of migration processes.
