Authors: Uçaroğlu Selnur , Yeşil Aybüke
Published: December 2024

Toprak kalitesini iyileştirmek için çeşitli organik maddeler kullanılır ve yüksek azot içeriği ve bulunabilirliği nedeniyle arıtma çamuru ve vermikompost (solucan gübresi) tercih edilen toprak düzenleyicileri arasındadır. Bu çalışma, gıda endüstrisinden gelen arıtma çamurunun ve inek gübresinden elde edilen vermikompostun toprak özellikleri ve azot süreçleri üzerindeki etkilerini değerlendirmeyi amaçlamaktadır. Özellikle, arıtma çamuru ve vermikompost, alan topraklara 150 kg N/da azot sağlayamak için uygulanmış ve topraklar 90 gün boyunca inkübe edilmiştir. pH, elektriksel iletkenlik, toplam azot, amonyum azotu ve nitrat azotu 0, 30, 60 ve 90. günlerde izlenmiştir. Toprağa organik atıkların eklenmesi, izlenen tüm parametreleri artırmıştır. Her iki organik düzenleyici de mikrobiyal aktiviteyi artırarak topraktaki toplam azot, amonyum azotu ve nitrat azotu seviyelerini önemli ölçüde artırmıştır ve artış özellikle arıtma çamuru uygulanan topraklarda daha belirgin olmuştur. Arıtma çamuru ve vermikompostun, yasal düzenlemelerdeki gereklilikleri karşıladıkları takdirde diğer geleneksel azotlu gübrelere alternatif olabileceği düşünülmektedir.
General extraction of alkaloids in acidic medium v1
Authors: Pereira de Jesus Rômulo , M. Borges Ricardo
Published: December 2024

This protocol describes an efficient method for the extraction and qualitative detection of alkaloids in plant samples using organic solvents in an acidic medium. The procedure includes extraction in an acidic medium and partitioning with ethyl acetate after alkalinization. The mixture is subjected to ultrasound and centrifugation processes, enabling the separation of alkaloids in the organic phase. The solvent is subsequently evaporated to obtain the compounds in their pure form. Qualitative identification is carried out using Dragendorff's reagent, which indicates the presence of alkaloids through the formation of orange to red precipitates. This method combines simplicity, reproducibility, and efficiency, making it suitable for phytochemical studies of natural products.
CBCAcoNH_3D.nan v1
Authors: KB NAN
Published: December 2024

This protocol describes running a 3D CBCA(CO)NH pulse sequence with sensitivity enhancement, gradient coherence selection, using either uniform or non-uniform sampling (NUS). This produces a 3D phase-sensitive dataset that correlates backbone 1HN and 15N resonances of residue (i) with 13CA and 13CB of residue (i-1). Has higher sensitivity than HNCACB, and thus may provide 13CA(i-1) and 13CB(i-1) shifts in cases when the corresponding peaks are not detected in HNCACB. Required isotope labeling: U-15N,13C. Not suitable for samples with additional 2H labeling due to starting with 1HA and 1HB polarization; HN(CO)CACB or TROSY-HN(CO)CACB with 2H decoupling should be used in this case. Optimal MW is ≤ 25 kDa. Larger systems may benefit from 3D CBCA(CO)NH-TROSY version; compare 2D H-N planes to check which one yields better S/N. This pulse sequence can be used for: spin system identification resolving signal degeneracy in 2D 15N HSQC backbone resonance assignment: sequential linking of spins systems based on 13CA and 13CB peak matching in conjunction with 3D HNCACB or HNCA spectra residue type information mainly based on CB shifts resonance assignment of 13CA and 13CB spins chemical shift-based secondary structure prediction (e.g. TALOS), together with other resonances Field strength preference: Lower B0 fields (600-700 MHz) are preferred, due to R2 relaxation affecting 13CO coherences during long constant-time magnetization transfer periods. The R2 relaxation rate of 13CO resonances is dominated by chemical shift anisotropy and is proportional to B0 squared. It uses the standard Bruker Topspin pulseprogram 'cbcaconhgp3d'
The variety of forms in modern humanitarian diplomacy: Different interpretations
Authors: Gribovod E. G.
Published: December 2024

The global humanitarian architecture has undergone changes influenced by a broad spectrum of problems, emergencies, and both man-made and natural disasters. One of the trends in its development is the activation of non-Western actors contributing substantially to expanding the tools of humanitarian diplomatic practice. Modern crisis phenomena in world politics have underscored the need for the scientific community to revise basic approaches and conceptual frameworks of international humanitarian cooperation. One such attempt is the collective monograph “Humanitarian diplomacy: Civilizational and national models”, prepared under the leadership of Professor Olga Bogatyreva, which serves as a continuation of the book published in 2021. This article provides a critical analysis the main provisions of the monograph and reveals two perspectives on studying modern models of humanitarian diplomacy. On the one hand, the authors examine them through the prism of the multi-level structure of diplomatic practice. On the other hand, they strive to go beyond traditional research optics, highlighting and analyzing the civilizational a spects of humanitarian diplomacy. The book under review attempts to characterize the structure of humanitarian diplomacy in the Mediterranean region, Latin America and the Caribbean, and to identify the main actors and key areas of humanitarian action. One of the chapters discusses China’s national model. The authors of the monograph conclude that national and civilizational models of humanitarian diplomacy are shaped by a complex of factors: firstly, historical, cultural, political, legal, economic principles, and traditions; secondly, the existing structure of providing humanitarian assistance in a specific region and national concepts of humanitarian policy.
The cognitariat. Specifics of formation and prospects for development in Russi
Authors: Bresler M. G.
Published: December 2024

As the information society evolves, new classes emerge, and among them is the cognitariat – the producing class responsible for creating information products and communication networks. Employing an information communication method, the article provides a socio-philosophical analysis of key values within the cognitariat, emphasizing creative work and the imperative of societal demand. Glocal peculiarities of the cognitariat in Russia are highlighted. Originating in the 1960s–1980s, unlike in capitalist countries, the Russian cognitariat did not emerge from workers in the service sector engaged in immaterial labor but rather from “working intellectuals”. Alongside with the “technical” and “creative intellectuals”, they successfully overcome the dramatic consequences of the 1990s, securing a leading position in the middle strata of society and shaping its development trends in the 21st century. The optimistic outlook for the development of the Russian cognitariat is rooted in the study of the cognitariat of Generation Z (centennials) – the first generation of the new information/digital society. Recognizing the need of adapting public space to the values of these new generations, it is concluded that the cognitariat is turning into an important productive force. Consequently, the overall societal development largely depends on creating favorable conditions for this social group and fostering its harmonious interaction with other classes. In addition, this approach facilitates the effective utilization of the cognitariat’s creative potential for national development. This conclusion holds practical significance and should be taken into account in the formulation of strategic plans at local and regional levels.
Exogenous and Endogenous Constraints of Rationality in the Political Decision-Making Process
Authors: Yalmanov N. I.
Published: December 2024

One of the key problems in political decision-making is to rationalize those decisions. The theory of rational choice has long set methodological guidelines for research in this area. A neo-positivist approach towards the definition of incentives and responses, together with fundamental meta-principles of neoclassical economic tradition (such as efficiency, completeness of information, reactivity, intentionality), determined the point of view according to which a rationally justified decision is tied to effectiveness of goals and means. Today, new scientific directions are appearing that seek to change the established theoretical and methodological framework. Attention to the cognitive characteristics of decision-making actors in conditions of risk and uncertainty has stimulated a number of studies to emerge that have considered rationality from a new angle. Achievements of neoclassical, behavioral and naturalistic approaches formed an extensive research base for this. At the same time, this study is relevant not only due to some new concepts appearing in the socio-political sciences that change the concept of rationality, but also due to changing the nature of factors that affect the possibility of rational choice, including political decision-making. Based on the analysis and consideration of these approaches, an attempt has been made to form an integral semantic field around the concept of rationality as an attribute of solutions. Exogenous and endogenous factors limiting the achievement of politically significant results are emphasized. It is proved that restrictive factors can not only influence the final results of decisions, but also they can significantly determine the content of the procedure for rationalizing the choice itself; however cognitive capabilities of decision makers and analytical tools for assessing external conditions play an important part. Methodology includes studying dynamic aspects of choice under the conditions of risk and uncertainty, when an inversion of rational choice strategies occurs based on the influence of exogenous or endogenous constraints.
“Neither Bread, nor Circuses”: Cancel Culture in Sports as a Practice of Oblivion
Authors: Ivanov A. G.
Published: December 2024

Cancel culture, which has recently emerged as a significant aspect of the intellectual life of the West, possesses a broader historical context that aligns with the techniques and forms of Oblivion outlined by Aleida Assmann. The evolution of this form of ostracism is illustrated through the lens of elite sports – from the instances involving the USSR during the Cold War to recent events concerning the Russian Federation, where the decline of international competitions requires administrative decisions. Historically, cancelling in sports can be traced back to boycotts, a practice representing the act of ignoring as a technique of oblivion; however, it has now evolved into a complex network of varied actors, practices, and intricate relationships. Through content analysis of both Russian and Western publications, the primary actors have been identified – the international organizations, governments of participating and organizing countries, athletes, and fans – and their reactions during instances of boycotts, restrictions on the use of national symbols, requirements for neutral status were examined. Special emphasis was placed on the forms of negative oblivion that became prevalent at the beginning of XXIst century amidst doping scandals and geopolitical confrontation. Illustrative cases of selective oblivion, particularly those concerning the Soviet sports legacy, such as the 1980 Summer Olympics in Moscow, support the potential of employing the concept of mythscape. It is noted that contemporary professional sports serve as a particularly revealing arena for the manifestation of cancel culture practices, which have significant effects in the political, economic and social spheres. The conclusions drawn indicate the dominance of unprecedented sports policy globally, resulting in fundamental changes both in the nature of major sports (including the erosion of the Olympic movement) and in the frameworks for organizing significant tournaments.

This study investigates the structural application of fiber-reinforced concrete using coir and plastic fibers. The experiment incorporated various percentages of fibers in concrete: coir fiber and plastic fibers at 0.5%, 1%, 1.5%, and 2%. An over-all of 80 concrete cubes, 42 cylinders, and 40 prisms were cast and examined to assess various mechanical properties. Compressive strength, and durability tests were conducted on the concrete cubes. The cylinders were subjected to split tensile tests and stress-strain behavior evaluations. The prisms underwent flexural strength tests to determine their performance under load. Additionally, the study included reinforced concrete beams reinforced with steel and fibers, and one beam with fibers only. Flexural strength tests were conducted on these beams, resulting in stress-strain behavior and load-deflection. Advanced characterization techniques such as Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and Fourier Transform Infrared Spectroscopy (FTIR) were applied to end sample powders of both normal and optimized mixes The findings indicate that the incorporation of 1% coir and plastic fibers significantly enhances the mechanical performance of concrete. The results from compressive strength, tensile strength, and flexural strength tests recommend that fiber reinforcement improves the durability and structural integrity of concrete. The SEM, EDX, and FTIR analyses provided insights into the microstructural changes and bonding characteristics of the fiber-reinforced concrete, corroborating the mechanical test outcomes. In conclusion, the study demonstrates that fiber-reinforced concrete, particularly with 1% coir and plastic fibers, the 1% of coir sample increased tensile strength by 10% and flexural strength by 20%, while the 1% plastic fiber improved flexural strength by 50% and split tensile strength by 30%. It is a viable and sustainable option for enhancing the mechanical performance and durability of concrete structures. This creative approach has potential for building environmentally friendly concrete infrastructure.

The hybridization of natural fibres improves composite development by compensating the drawbacks of single fibre reinforcement in a polymer matrix. This study examined the influence of rice husks, eggshells, and banana fibres on the mechanical properties of an epoxy polymer composite with the aim of developing a sustainable composite material with improved mechanical properties from agricultural wastes. The composites were developed from varied proportions of banana fibre (BF) and eggshell (ES) with constant rice husks (RH) in an epoxy polymer matrix; 5:20:20, 10:15:20, 15:10:20, and 20:5:20 respectively. The BF and RH were treated with 5% NaOH before its usage as a reinforcement. The mechanical properties; flexural, tensile, and impact strength of the cured samples were investigated and the test results revealed that hybridized BF/ES/RH enhanced the mechanical properties of the epoxy polymer matrix composite. The best flexural, tensile, and impact strength was obtained at composition 15:10:20 BF/ES/RH. The flexural, tensile, impact strength, flexural modulus, and tensile modulus ranged from 3.66 to 25.06 MPa, 11.35 to 17.42 MPa, 14.98 to 28.61 J/mm2, 133.80 to 850.75 MPa, and 469.18 to 1872.09 MPa respectively. The composite exhibited 64.7%, 9.3%, and 39.84% improvements in flexural, tensile, and impact strength, respectively, over the control sample. The BF, ES, and RH contribute to the composite’s tensile strength, impact resistance, and rigidity respectively. The result showed that the composite is suitable for various applications in engineering such as car door panels due to its improved mechanical strength while causing a reduction of waste circulation in the environment.

The optimization of wind turbine performance is a critical issue for enhancing energy conversion efficiency. This study investigates the effects of blade pitch angles and Variable Frequency Drive settings on the performance of a wind turbine system using the Spectra Quest wind turbine simulator. Employing a Taguchi design of experiments with a full factorial approach, a total of 81 experimental tests are conducted to analyze the influence of three blade pitch angles (0°, 10°, and 20°) combined with three distinct Variable Frequency Drive settings (12, 15, and 18) on shaft rotational speed, power output, and vibration levels. Using Taguchi's response analysis and analysis of variance, this research identifies Variable Frequency Drive as the most influential factor on turbine performance metrics. Regression modelling further elucidates the complex relationships between the operational parameters and performance outcomes. The results reveal significant interactions between the input parameters and demonstrate that lower blade pitch angles in conjunction with higher Variable Frequency Drive settings maximize both shaft rotational speed (171 rpm) and power output (24.102 W), maintaining acceptable vibration levels. The best pitch angle input parameters are found to be β1=0o, β2=0o and β3=0o with a VFD setting of 18. A notable increase in air resistance at higher pitch angles corroborates the findings of previous studies, highlighting the need for optimal parameter settings to enhance turbine efficiency.

El «Ser Otro» y la emancipación de la mujer
Authors:   Universidad del Tolima, Zamudio Giraldo Laura Del Mar
Published: December 2024

El matrimonio ejerce una influencia profunda en la vida individual, moldeando las formas de vida, comportamientos y perspectivas de cada persona. En la novela 'Los días del abandono' de Elena Ferrante, se explora la pérdida de identidad y el abandono de sí mismo que puede ocurrir en el contexto matrimonial, afectando la autoconciencia y el desarrollo del individuo. Este texto se propone analizar la pérdida de identidad de la mujer en el matrimonio, considerándola como un 'Ser Otro' en este entorno, y además, busca destacar la importancia de la emancipación y autonomía femenina. Se estructura en torno a tres categorías clave: Matrimonio, Familia y maternidad, y Emancipación. Para lograr este objetivo, se realiza un análisis hermenéutico que relaciona el universo de la obra con la teoría de Simone de Beauvoir, con el fin de construir un análisis significativo sobre la formación de la identidad femenina en el proceso de separación y comprender cómo la dependencia emocional impacta su desarrollo personal. En suma, los días del abandono representa la transición de la mujer desde el ser Otro al Sujeto mujer emancipado, atravesando con ello, la imposición y la pérdida de sí a causa del matrimonio, la familia y su infancia; más aún, establece una mirada al manejo de las emociones, la incidencia que tienen las condiciones sociales, el contexto y la experiencia en la forma de ser del individuo, su espacio y sobre todo, en las relaciones que entabla con los hijos, con los vecinos y consigo misma.

The article considers the basic notions of strategic and risk management of entities as an essential factor in ensuring efficient functioning and adaptation to the fast-changing conditions of the external environment. Implementation of risk management into the strategic management system is a valuable factor for a company's effective functioning in complex conditions of the contemporary business environment. Embodying a company's strategic plans demands considering the ambiguity of the environment and carrying managerial influence on risks as a must during the implementation of any strategy. That is why, when developing and implementing any strategy, one must consider associated risks. The article defines the place of risk management in the strategic planning process. It proves that being integrated into strategic planning, risk management enables the minimization of their negative effect on reaching organizational goals. The author offers a procedure to carry out risk-considering strategical management, stipulating ten successive steps: identification, analysis and assessment, elaborating responses based on the risk assessment results, choosing a method for risk management (processing risks), selecting managerial actions for risk processing, development risks management strategy, implementation, assessment of the strategy results, risks monitoring, corrections to the strategy. Risk management implementation into the general organizational strategy enables the minimization of probable losses within the uncertainty of conditions. The article contains a comparative analysis of qualitative and quantitative risk assessment methods. The represented pattern of the risk assessment and management methods enables the selection of the one that fits excellently to the internal and external environment of a company and ensures the effective delivery of the strategy. Risk monitoring has been demonstrated to be one of the basement risk-management tools. Risk monitoring shall accompany the whole strategy implementation process to detect any deviations between actual risk levels and forecasted ones and correct the implementation of the strategy.

Силовой электронный преобразователь, известный как Zeta-преобразователь, широко используется в различных приложениях, включая системы возобновляемых источников энергии и источники питания. Несмотря на свои преимущества при преобразовании фотоэлектрических источников, такие как одноступенчатое преобразование мощности и регулировка коэффициента мощности, обычные Zeta-преобразователи сталкиваются с ограничениями в эффективности и адаптируемости из-за их узкого рабочего диапазона и дополнительных схем. Для решения этих проблем в этом исследовании предлагается усовершенствованная архитектура Zeta-преобразователя с высоким повышающим коэффициентом, адаптированная для фотоэлектрических систем, подключенных к сети. Предлагаемый преобразователь обеспечивает исключительную регулировку коэффициента мощности и может работать с широким диапазоном входных напряжений, обеспечивая оптимальную производительность даже в различных условиях окружающей среды. Активно выравнивая входной ток с входным напряжением, преобразователь достигает коэффициента мощности, близкого к единице, минимизируя содержание гармоник и повышая эффективность системы. Кроме того, чередующийся режим работы снижает шум переключения и скачки напряжения, что приводит к снижению электромагнитных помех. Это делает предлагаемый преобразователь очень подходящим для фотоэлектрических систем, подключенных к сети, где надежное преобразование энергии и ее качественная доставка имеют первостепенное значение. Универсальность преобразователя делает его применимым не только для фотоэлектрических систем, но и для других сценариев, требующих большего выходного напряжения, чем входное, например, для драйверов светодиодов или некоторых приложений DC-DC-преобразования.

При проектировании железнодорожного пути в условиях многолетних мерзлых грунтов необходимо правильно выбирать материалы для возведения земляного полотна и насыпи. В качестве характерного примера рассматривается участок Цинхай-Тибетской железной дороги, для которого известны упругие параметры сред, входящих в состав железнодорожного пути, земляного полотна и слои мерзлых грунтов. Используется сеточно-характеристический метод для моделирования прохождения упругих волн от зон скреплений рельсов и шпалы в поперечном срезе железнодорожного пути. При решении прямой задачи численного ультразвукового исследования конструкции пути в условиях варьирования основания балластной призмы от насыпного грунт к каменному щебню, получены поля модуля вектора скорости и вертикальной нагрузки в различные моменты времени. Анализ полученных результатов показывает целесообразность использования в качестве основания каменный щебень при проектировании насыпи, что согласуется с результатами других исследователей, использующих конечно-элементные подходы.

REFLEXÕES SOBRE A MODERNIZAÇÃO DOS REGIMES ALIMENTARES EM PEQUENOS MUNICÍPIOS
Authors: De Souza Tainara , Vitorino Madeira Beatriz , Azevedo da Silva Clécio
Published: December 2024

No contexto atual, de progressivas transformações e rearranjos técnicos e organizacionais na produção, distribuição e consumo de alimentos provocados pelo desenvolvimento do capitalismo, os regimes alimentares nos pequenos municípios são pressionados a acompanhar essas mudanças, estimulando a incorporação de novos padrões alimentares. O presente trabalho resulta de uma pesquisa de iniciação científica (PIBIC/CNPq 2022-2023) cujo principal objetivo foi analisar as mudanças nos regimes alimentares em pequenas localidades provocadas pela modernização. Para tal, foram levantadas informações por meio de conversas com famílias agricultoras, além de pesquisa bibliográfica. Como resultado, foi observado que as mudanças nas relações e no objetivo do trabalho rural, orientadas pela modernização da agricultura, configuram a principal porta de entrada de alimentos industrializados na dieta das famílias. Observou-se também que o abandono da monocultura e o retorno ao autoconsumo proporciona maior diversidade e qualidade dos alimentos produzidos, além de maior autonomia para a adoção de práticas sustentáveis.
PATRIMÔNIO FERROVIÁRIO COMO EQUIPAMENTO URBANO EM PEQUENAS CIDADES
Authors: Alves Goulart Rocha Beatriz
Published: December 2024

O presente artigo faz parte de uma pesquisa de doutorado em desenvolvimento acerca da preservação do patrimônio ferroviário em cidades de pequeno porte. Portanto, tem como principal recorte de estudos a denominada “Linha do Rio Grande”, porção da antiga Companhia Mogiana de Estradas de Ferro. Isto porque, a maior parte das cidades que eram contempladas por esta ferrovia são de pequeno porte. Contemplando especialmente as antigas estações ferroviárias situadas na zona urbana, bem como o espaço livre encontrado em seu entorno, pretende-se demonstrar que estes locais possuem um grande potencial como equipamento urbano, tanto para cultura e lazer, quanto para diversos usos que sejam coerentes com as demandas locais
SEGURANÇA PÚBLICA EM PEQUENAS CIDADES DO NORTE PIONEIRO DO PARANÁ
Authors: Carnevalli Fernandes Pedro Henrique
Published: December 2024

A segurança pública se converteu em um dos principais temas da agenda brasileira, fazendo parte, constantemente, de publicações acadêmicas, debates políticos, programas televisivos, redes sociais e conversas cotidianas. Na Geografia, o tema pode ser abordado na Geografia da Violência, na qual os estudos espacializam a base empírica e promovem reflexões pautadas nas questões sociais. O objetivo central deste artigo é refletir acerca da segurança pública em pequenas cidades a partir dos investimentos municipais em segurança pública e das ocorrências de violência, na Região Geográfica Imediata de Cornélio Procópio-Bandeirantes, no Norte Pioneiro do Estado do Paraná. Os procedimentos metodológicos foram: levantamento de referenciais teóricos; levantamentos dos investimentos municipais em segurança pública e de dados de violência, elaboração de produções cartográficas; e sistematização das informações na redação final. Os principais resultados revelam que a esmagadora maioria dos municípios da região não investiu nenhum recurso público em segurança. Em contrapartida, muitos deles apresentam altas taxas de crimes contra a pessoa e contra o patrimônio
Characterizations of Certain (2023-2024) Introduced Univariate Continuous Distributions
Authors: Hamedani G. G. , Roshani Amin , Shafique Butt Nadeem
Published: December 2024

This paper deals with various characterizations of certain univariate continuous distributions proposed in (2023-2024). These characterizations are based on: (i) a simple relationship between two truncated moments; (ii) the hazard function; (iii) reverse hazard function and (iv) conditional expectation of a single function of the random variable. It should be mentioned that for the characterization (i) the cumulative distribution function need not have a closed form and depends on the solution of a first order differential equation, which provides a bridge betweenprobability and differential equation.
Infection in nicu setting pose serious health risks to neonates - A meta-analysis
Authors: Sangati Chetan Ramesh , Pradeep M
Published: December 2024

Infections in Neonatal Intensive Care Units (NICUs) pose significant health risks to neonates, particularly due to their underdeveloped immune systems and the invasive procedures often necessary for treatment. These infections can lead to severe complications, prolonged hospital stays, and increased mortality rates.

This meta-analysis aims to assess the prevalence, risk factors, outcomes, and preventive strategies associated with infections in NICU settings to better understand the scope of the problem and provide insights for improved healthcare practices.

A systematic search was conducted across multiple databases, including PubMed, CINAHL, and Medline, for peer-reviewed studies published in the last two decades. Studies were selected based on criteria that included focus on NICU-acquired infections, study design, and outcomes reported on neonatal health. Data on infection prevalence, types, risk factors, treatment efficacy, and preventive interventions were extracted and analyzed using meta-analytic techniques to calculate pooled estimates and examine statistical associations.

Findings indicate a high prevalence of infections in NICUs, with bloodstream infections, pneumonia, and urinary tract infections as the most common types. Risk factors such as prematurity, low birth weight, invasive procedures, and prolonged NICU stay significantly increase infection rates. Neonates with infections demonstrated higher morbidity, longer hospital stays, and a higher risk of long-term health complications. Preventive measures, particularly hand hygiene protocols, sterilization practices, and early identification strategies, were associated with reduced infection rates.

Infections in NICUs remain a critical issue, impacting neonatal outcomes and healthcare costs. Strengthening preventive measures and developing standardized protocols for infection control are essential to reduce infection rates and improve neonatal health outcomes. Further research is needed to identify the most effective interventions and foster a culture of infection prevention within NICU settings.

Nursing education is crucial for producing skilled healthcare professionals.However, nursing teachers face various challenges during paper evaluation, which can affect the effectiveness of the assessment process.

This study aims to assess these issues and explore their association with demographic variables.

A descriptive research design was used, conducted in selected nursing colleges with a sample of 50 nursing teachers.

Data was collected using a self-administered structured questionnaire, and analyzed with descriptive and inferential statistics.

The questionnaire showed high reliability (0.7593).

Nursing teachers face various challenges during paper evaluation. Common issues include unreadable handwriting (12%), irrelevant answers (4%), and incorrect numbering (6%). Long-answer questions are the most difficult to assess (40%), while 80% evaluate 20–40 papers daily, often requiring extra hours (24%). Presentation challenges (58%) and emotional strain (40%) further complicate the process. While 34% prefer digital evaluation, specialization (p = 0.005) and designation (p = 0.0001) significantly influence these challenges, but age (p = 0.48) and MUHS experience (p = 0.60) show no significant association.

Nursing teachers face significant challenges during paper evaluation, including difficulty with long-answer questions, presentation issues, and emotional strain. Specialization and designation significantly influence these challenges, while age and experience in MUHS evaluation do not. The findings highlight the need for streamlined evaluation processes, with a preference for digital methods to improve efficiency and reduce stress.
