Vloga športa za zdrav osebnostni razvoj otrok in mladostnikov
Authors: Tušak Matej , Tušak Maks
Published: August 2024

Vrednota gibanja in ukvarjanja s telesno aktivnostjo se oblikuje – kakor vse vrednote – že v najzgodnejšem okolju. Starši imajo pri oblikovanju skrbi za zdravje skozi redno ukvarjanje s telesno vadbo ključni pomen, ne smemo pa zanemariti niti vpliva učiteljev, vrstnikov in trenerjev. Otroci, ki so se v mladosti aktivno ukvarjali s športom, so dokazano bolj telesno aktivni tudi v odraslem obdobju. Pravimo, da so ponotranjili potrebo po telesni aktivnosti. Dobro psihofizično pripravljen otrok in mladostnik pa je bistveno bolje usposobljen za reagiranje na stresorje, s katerimi se bo moral v življenju soočati. Razumeti preventivni pomen redne telesne aktivnosti za zagotavljanje zdravja pa seveda še ne pomeni, da bo posameznik v obdobju odraslosti v resnici tudi telesno aktiven. V obdobju otroštva in mladostništva imamo za otroke v šolah obvezno telesno vzgojo; po prihodu na fakultete in v obdobju odraslosti pa je vse odvisno od posameznikovega odnosa do gibanja, zato je promocija telesne aktivnosti tudi v obdobju odraslosti nujna.

Published: August 2024

In Mongolia, the Ulan lead-zinc mine is now struggling with high backfill operating costs and poor Cemented Paste Backfill (CPB) mechanical performance after curing. To solve this problem, BGRIMM Technology Group has investigated an activator that could mix with fly ash from Choibalsan Power Plant in Mongolia as a supplementary cementitious material for backfill. In this study, the mechanical performance of CPB samples prepared with various fly ash content and activator types were studied to provide a basis for the industrial application of fly ash-based supplementary cementitious materials. The research results indicate that partially replacing cement with fly ash reduces the uniaxial compressive strength (UCS) of CPB samples. Compared with the CPB sample prepared with pure cement, when the fly ash substitution rate is 10%, 20%, and 30%, the UCS reduced by 15.66%, 18.69%, and 32.83%, respectively. With the use of chemical activators, the UCS of CPB samples could be significantly improved. Among them, CPB samples prepared by the activator sodium sulfate+ sodium chloride+ TEA have achieved the highest UCS. Overall, this study shows that the synergistic effect of fly ash and chemical activators could effectively enhance the mechanical performance of CPB, which is beneficial for mine backfill cost reduction and could provide a basis for the further industrial application of fly ash-based cementitious materials in mine backfill.

Studi Tafsir Tematik: Kajian Nanopartikel Menurut Al-Qur’an Serta Pemanfaatannya di Bidang Medis
Authors: Maulahibati Farah Fauzia , Syarifah Umaiyatus , Minarno Eko Budi
Published: August 2024

Nanoparticles are small particles that can penetrate physiological barriers in the body and circulate in the circulatory system. Nanoparticles are very small, just like atoms, which cannot be seen directly by the eye and require a microscope to see them. Nanoparticles are made with a very small size to overcome difficulties in dissolving active substances, improve poor bioviability of compounds, and directly modify drug delivery systems to specific areas. The Qur'an does not specifically discuss nanoparticles, but the Qur'an explains it implicitly in the word zarrah which is repeated 6 times. The repetition of the word zarrah is in Q.S An-Nisa'/4 verse 40, Q.S Yunus/10 verse 61, Q.S Saba'/34 verse 3, Q.S Saba'/34 verse 22, and Q.S Al-Zalzalah/99 verses 7-8. This research method uses thematic interpretation, namely the method of interpretation through the collection of verses of the Qur’an with the same topic to be studied. Scholars and commentators interpret zarrah as a small seed or red ant head or something small in size. Modern commentators always associate zarrah with atoms because of their very small size. Along with the times, there is currently a new technology in the medical world that uses small particles such as atoms known as nanoparticles

Published: August 2024

Clean and Healthy Living Behavior or often abbreviated as PHBS is the behavior or action of seeking cleanliness and health from one's own volition and transmitting it to others. This behavior includes maintaining personal hygiene and health so that it impacts the health of others and the surrounding environment. This research was conducted in Tegalweru Village, Kec. In his environment, Dau Malang Regency found that there are still many public places and local residents who do not understand how to carry out good and correct PHBS. Therefore KKM students carry out socialization related to OHBS in order to create a prosperous society. Implementing PHBS in the community can be said to be difficult considering there is still a lack of awareness within each one. Even though it's not only from health, but religion also often reminds of cleanliness. Because cleanliness is the beginning of a healthy life. If healthy, activities can be carried out including in worshiping God Almighty. The aim of this research is to see how the religious side is related to PHBS. The research method used is descriptive. The results obtained from this study are that religion strongly supports a clean and healthy lifestyle. Even one hadith confirms that cleanliness is part of faith.

Published: August 2024

Las habilidades necesarias para seleccionar, evaluar y sintetizar información de múltiples fuentes en internet son esenciales para los estudiantes de educación superior. Este estudio se enfocó en investigar cómo los estudiantes de un programa de formación de profesores en Chile abordan problemas que requieren la búsqueda de información y si existen diferencias en su enfoque al realizar estas tareas. Se utilizó el Índice de Desempeño de Búsqueda para clasificar a los participantes en tres grupos según su eficacia y eficiencia en la obtención de resultados. A través de registros computacionales, se compararon los grupos en su proceso de búsqueda de respuestas. Los datos fueron recopilados mediante un software de monitoreo (SurveilStar) y analizados a través SSPS v. 21. Los resultados dan cuenta de las estrategias más y menos exitosas empleadas por los estudiantes en la búsqueda de información. Se observó que los buscadores más eficientes se enfocan en un conjunto reducido de palabras clave, lo que aumenta sus posibilidades de encontrar respuestas de manera más rápida y eficaz, reduciendo el tiempo de escritura. Este hallazgo concuerda con investigaciones previas que sugieren que la formulación de consultas más elaboradas conduce a búsquedas más exitosas. Estos resultados tienen implicaciones importantes para la enseñanza y el desarrollo de habilidades de búsqueda de información en estudiantes de educación superior en Chile.
Breast Milk Microbiota: A Systematic Review on the Influence of Maternal Characteristics on Human Milk Composition
Authors: Abrigo Karen , Püschel Cristian , Barrera Cynthia , Gotteland Martin
Published: August 2024

Objective:The objective of this study was to identify current evidence on the impact of maternal characteristics (nutritional status, diet, geographic location/cultural influences, and stress) on breast milk microbiota (BMM) composition and diversity.

Methods:A systematic review was conducted by searching articles in five different databases. Quality and risk of bias were assessed for each article using RevMan software.

Results:Fifteen articles were selected. Maternal obesity had only a transient effect on microbiota diversity. Dietary fatty acids and folates were the main dietary factors influencing BMM. Maternal geographic location strongly influences BMM composition and ultimately its diversity. Available data on maternal stress were insufficient to draw conclusions regarding the impact of this factor.

Conclusions:Geographic location of the mother and dietary factors are the main determinants of BMM composition. Further studies are needed to assess the impact of BMM on infant health.
Healthcare Professionals’ Perspectives on Perinatal Well-Being Across the Perinatal Period
Authors: Glover Lesley , Jomeen Julie , Marsden Julia , Wadephul Franziska
Published: August 2024

OBJECTIVE:Perinatal well-being (PWB) is holistic, multifaceted, and more than the absence or low levels of adverse physical, emotional, and mental elements. Little is known about the understanding of perinatal well-being (WB) by perinatal healthcare professionals (HCPs). The objectives were twofold: (a) to explore what perinatal HCPs understand by PWB and (b) to explore what they perceive influences PWB.

METHODS:Nine UK-based HCPs (n= 4 health visitors,n= 4 perinatal mental health clinicians,n= 1 midwife, andn= 1 General Practitioner) caring for women during the perinatal period completed an online qualitative survey relating to PWB. Participants also ranked factors which may potentially influence PWB.

RESULTS:Four overarching themes were developed from the qualitative responses encompassing different aspects of PWB including the context of women’s WB, the dynamic nature of this period, and the role of HCPs. They also characterized the period as a uniquely stressful and risky time.

CONCLUSIONS:HCPs predominantly described physical and mental elements when discussing PWB. Some did mention the importance of financial, spiritual, and relational elements. The predominant focus on physical and mental aspects of WB may reflect the biomedical model underpinning perinatal/maternity care provision. The pros, cons, and implications of a move toward a more WB-focused approach within policy and practice are an area for future research.

Published: August 2024

The consideration of students’ emotional and psychological health is crucial to facilitate effective teaching and grading practices. This study set out to shed light on the interplay between self-esteem (S-E), cognitive-emotion regulation (CER), academic enjoyment (AE), and language success (LS) in artificial intelligence (AI)-supported online language learning. To this end, the foreign language learning self-esteem scale, the Cognitive Emotion Control Questionnaire, the foreign language enjoyment scale, and a researcher-made test were distributed to 389 English as a foreign language learners in China. Screening the data with confirmatory factor analysis and structural equation modeling, the effects of S-E, CER, AE, and LS were identified and quantified. These results highlighted the important function that online courses assisted by AI perform in enhancing students’ CER and AE. This implied that students who have cultivated a robust sense of self-efficacy are adept at effectively regulating their cognitive and affective processes in AI-supported language learning. Possible improvements in language education are discussed, as are the study’s broader implications.

Authors: Ouyang Zhiqun , Jiang Yujun , Liu Huying
Published: August 2024

This study, which is quasi-experimental in nature, looks into how language learners’ willingness to communicate and engagement in English as a foreign language (EFL) classrooms are affected by Duolingo. The control and experimental groups comprised two complete classes with forty EFL students. To compare learner engagement and communication willingness scores before and after treatment, the study used independent samples t-tests. The results demonstrated the groups’ initial homogeneity by showing no discernible differences prior to the intervention. The results confirmed the effects on learner engagement, which showed significant gains in affective, cognitive, and behavioral domains, indicating Duolingo’s beneficial impact on engagement in general. Furthermore, the significant effect sizes observed confirmed Duolingo’s contribution to improved language attitudes, engagement, and communicative confidence. Compared to the control group, the experimental group’s willingness to speak, read, write, comprehend, and communicate generally improved in a manner that was statistically significant. The significant effect sizes demonstrate how well Duolingo works to improve different aspects of willingness to share. The study emphasizes the pedagogical tool’s adaptability and encourages teachers to integrate Duolingo for a comprehensive and technologically enhanced language learning experience. Practical implications arise for EFL teachers who use online learning resources.
Les teckeraies de Casamance. Capacité de production des peuplements, caractéristiques biologiques et maintien du potentiel productif des sols
Authors: Maheut J. , Dommergues Yvon
Published: August 2024

Après un bref historique de l'introduction du teck en Casamance, les auteurs donnent les résultats de comptages effectués dans différentes plantations de teck. Les rendements varient entre 10 et 12 mètres cubes par hectare et par an. Un graphique de cubature a été préparé. La deuxième partie de l'article est consacrée à l'étude de la couverture foliaire et de la biologie des sols des plantations de teck. Il apparaît que le teck est une essence exigeante et que l'humus se décompose rapidement en freinant la minéralisation de l'azote. Ces caractéristiques peuvent faire craindre une baisse de rendement de certains sols dans un avenir plus ou moins lointain. Les mesures préventives proposées sont l'application d'engrais minéraux, l'introduction en mélange ou en sous-bois d'espèces enrichissant le sol en azote minéral ou minéralisable tout en maintenant les teneurs organiques à un niveau satisfaisant.

Published: August 2024

The article reveals the main aspects of introducing a shortened work schedule into Russian labor practice. The relevance of the topic is currently confirmed not only by the demands of society, but also by the objective technological development of society. Employees of organizations around the world are waiting for changes in approaches to organizing working hours in accordance with the challenges of the time, which not only contribute to the transition to more flexible forms of employment, including remote work, but also to reducing working hours. Using the example of foreign practice of experiments with shortening working hours, the main options possible for using a shortened working week in the world and in Russia in particular are structured. Currently, the practice of switching to a four-day working week is being implemented with a reduction in the length of the working week, maintaining the number of working hours per week, as well as various options with maintaining or reducing wages. The problematic issues of the introduction of a shortened working week are highlighted, both on the part of employers, and on the part of the authorities and employees.
Political ethics of Xi Jinping — inheritance and development of the ideas of “Governing the country with kindness” of Confucianity and Marxist ethics
Authors:   Lomonosov Moscow State University, Panli Chen , Jiafeng Cai ,   Patrice Lumumba Peoples’ Friendship University of Russia
Published: August 2024

Modern China is an industrialized, high-tech state. But even at the beginning of the last century it was a semi-colonial and semi-feudal society. The Chinese people made a number of attempts to save the country and revive it, and finally found the path that suited them — the path of socialism with Chinese characteristics. The guiding ideology of socialism is Marxism, and the Chinese specificity is the traditional thoughts and culture ingrained in the mentality of the nation. The characteristic of the Chinese way is the perfect combination of these two philosophical thoughts. So how do you combine this? This article uses the example of Xi Jinping’s political ethics to analyze its guiding ideology — Confucius’s concept of governing the country with kindness and Marxist ethics. The authors first analyze the specific meaning of Xi Jinping’s political ethics, and then analyze the basis of the philosophical thought of his ethics: The set of political strategies included in the Confucian idea of virtue-based government: political strategies, talent strategies, economic strategies and management strategies; as well as the main characteristics of Marx’s ethics. This proves that building socialism with Chinese characteristics benefits from the high degree of compatibility between Marxism and traditional Chinese philosophical thought. The novelty of this article also lies in the fact that it talks about traditional Chinese Confucianism and Marxist philosophy in one dimension.
Epideictic speech: From classics to modernity
Authors:   Herzen State Pedagogical University of Russia, Verminenko Yulia V. , Zverev Sergey E. ,   Empress Catherine II Saint Petersburg Mining University
Published: August 2024

Epideictic (epidictic, demonstrative) speech has been considered since ancient times as one of the main genres of rhetorically developed speeches. In Aristotle, this rhetorical genre did not receive proper development, being pushed into the background by the most relevant deliberative and judicial speech for a competitive democracy. Epideictic speech in the oratorical practice of Ancient Greece and Rome was considered as a means of exercising eloquence as a pure art, and declamation as a school exercise for developing phonation skills. The publication in 1958 of the book X. Perelman and L. Olbrecht-Tyteki’s “New Rhetoric: A Treatise on Argumentation” marked a new reading of the rhetorical classics, which aroused interest in epideictic speech. The latter began to be considered as a tool that forms values in the public consciousness. In this regard, the researchers noted that rational argumentation, which is objectively based on the common views of the speaker and the audience, should not ignore the value and semantic orientations of listeners, which underlie their productive activities in accordance with the ideas laid down by deliberative and judicial speech. Epideictic speech is important for educational activities as an instrument of socialization, the formation of a worldview, and the education of commitment to values that have been living in the public consciousness for centuries, which makes its use by teachers and students effective.

Minimally invasive surgery approaches in major liver resection for hepatocellular carcinoma
Authors: Chatzipanagiotou Odysseas P. , Catalano Giovanni , Kawashima Jun , Pawlik Timothy M.
Published: August 2024

Over the past two decades, minimally invasive liver resection (MILR) has progressively become the standard for minor resection of hepatocellular carcinoma (HCC). In contrast, its implementation in major hepatectomy has been slower due to its higher technical complexity and morbidity. However, studies published in recent years have demonstrated that minimally invasive major hepatectomy (MIMH) is safe and feasible with less blood loss, fewer complications, earlier recovery, decreased hospital stay, and improved cosmetic outcomes compared with open surgery. This review examines the current status of MIMH, focusing on the respective strengths and weaknesses of the laparoscopic and robotic approaches, as well as assessing their cost-effectiveness and possible future directions. The earlier introduction of laparoscopic liver resection has led to its widespread utilization as a safe and accurate alternative to open hepatectomy. Of note is that the robotic approach has also been increasingly utilized, demonstrating better perioperative outcomes and decreased need for conversion to open hepatectomy vs. the laparoscopic approach. Advantages associated with the robotic approach include the three-dimensional large visual field and instrumental flexibility, allowing for improved bleeding control. Even though evidence has been slowly accumulating regarding long-term outcomes, most studies report no notable differences between open, robotic, and laparoscopic resection for HCC. Regarding cost-effectiveness, MIMH has been characterized by higher operating room and anesthesia costs, especially for robotic procedures that require highly expensive equipment. The increase in cost is often offset by the lower morbidity and, thus, shorter hospital stays associated with MIMH. Future developments, such as the implementation of artificial intelligence and augmented reality, may potentially maximize the safety and applicability of MIMH and, in time, lead to improved postoperative and oncological outcomes.
Neural mechanisms underlying upright bipedal gait: role of cortico-brainstem-spinal pathways involved in posture-gait control
Authors: Takakusaki Kaoru , Takahashi Mirai , Kaminishi Kohei , Fukuyama Shusei , Noguchi Tomohiro , Chiba Ryosuke , Ota Jun
Published: August 2024

Bipedal gait involves moving the body while maintaining an upright posture under gravity. Throughout vertebrate evolution and postnatal development, humans acquired antigravity functions that allow one to achieve biped gait. While walking, our attention is focused on purposeful, intentional movements such as dexterous arm-hand finger movements or searching for the target. On the other hand, postural control comes to our awareness only when we need to alter gait patterns, such as facing demanding conditions. Nonetheless, our body and brain control gait so as not to fall by anticipatorily adjusting posture that optimally achieves multi-tasks consisting of purposeful movements and walking. Accordingly, we have developed the working hypothesis that postural control is achieved by plans and programs that accomplish purposeful actions. Key questions to verify this hypothesis are (1) how higher brain functions brought about by evolution enabled us to acquire a bipedal standing posture that resists gravity and (2) how the frontal cortex, the most developed neocortical area, enabled us to acquire multi-tasks consisting of gait and intentional movements. We postulate that the frontoparietal networks that contribute to planning and programming based on cognitive information and corticofugal pathways that issue command signals to the subcortical structures, particularly the brainstem and spinal cord in which core systems of posture and gait control exist, play central roles in solving these questions. These mechanisms may be declined in older adults and impaired in patients with degenerative neurological disorders, resulting in posture-gait disturbance such as freezing of gait (FOG) and falling.

Furthermore, the handling of outliers was carried out using the numeric outliers node and data normalization to prepare the data before dividing the training and testing data. The models evaluated include Linear Regression, Random Forest Regression, Gradient Boosted Trees, and Multilayer Perceptron (MLP), with validation using 10 times cross-validation. The results showed that the Random Forest Regression and Gradient Boosted Trees models provided good prediction performance for both PM10 and PM2.5 parameters. Random Forest Regression showed the lowest RMSE value on testing data for PM10 (0.048) and PM2.5 (0.037), while Gradient Boosted Trees showed the lowest RMSE value on training data for PM2.5 (0.032). The process of handling outliers and normalizing the data successfully improved the prediction accuracy of the model. Suggestions for future research include the exploration of new models, the addition of meteorological and socio-economic variables, and the application of models in real-time air quality monitoring systems.

Abstract  
Cryptocurrency, particularly Bitcoin, has become a major topic in the financial and digital trading sectors due to its ability to facilitate direct transactions without intermediaries and the transparency offered by blockchain technology. However, the high volatility of Bitcoin prices necessitates accurate prediction methods to support better investment decisions. This research aims to compare the accuracy of Linear Regression and Long Short-Term Memory (LSTM) methods in predicting Bitcoin prices using historical data from Yahoo Finance. The research process begins with the collection of historical Bitcoin price data from September 17, 2014, to July 15, 2024, followed by data processing that includes cleaning and splitting the dataset into training and test data. Linear Regression and LSTM models are applied to the training data and tested to evaluate their performance in price prediction. The research findings show that the LSTM model significantly outperforms the Linear Regression model in terms of prediction accuracy. The LSTM model records much lower Mean Squared Error (MSE) and Root Mean Squared Error (RMSE), as well as perfect R² scores on both datasets, demonstrating its high precision in prediction. In contrast, the Linear Regression model shows higher errors and lower explanatory power of data variability. These findings indicate that LSTM is more effective in capturing temporal patterns and Bitcoin price fluctuations, offering better accuracy and potentially being more suitable for future cryptocurrency price analysis, providing better guidance for investors in this highly dynamic market.

Document similarity is a fundamental task in natural language processing and information retrieval, with applications ranging from plagiarism detection to recommendation systems. In this study, we leverage the term frequency-inverse document frequency (TF-IDF) to represent documents in a high-dimensional vector space, capturing their unique content while mitigating the influence of common terms. Subsequently, we employ the cosine similarity metric to measure the similarity between pairs of documents, which assesses the angle between their respective TF-IDF vectors. To evaluate the effectiveness of our approach, we conducted experiments on the Document Similarity Triplets Dataset, a benchmark dataset specifically designed for assessing document similarity techniques. Our experimental results demonstrate a significant performance with an accuracy score of 93.6% using bigram-only representation. However, we observed instances where false predictions occurred due to paired documents having similar terms but differing semantics, revealing a weakness in the TF-IDF approach. To address this limitation, future research could focus on augmenting document representations with semantic features. Incorporating semantic information, such as word embeddings or contextual embeddings, could enhance the model's ability to capture nuanced semantic relationships between documents, thereby improving accuracy in scenarios where term overlap does not adequately signify similarity.

This article develops duality principles and numerical results for a large class of non-convex variational models. The main results are based on fundamental tools of convex analysis, duality theory and calculus of variations. More specifically the approach is established for a class of non-convex functionals similar as those found in some models in phase transition. Finally, in some sections we present concerning numerical examples and the respective softwares.
A Note on Oppermann's Conjecture
Authors: Vega Frank
Published: August 2024

A prime gap is the difference between consecutive prime numbers. The $n^{\text{th}}$ prime gap, denoted $g_{n}$, is calculated by subtracting the $n^{\text{th}}$ prime from the $(n+1)^{\text{th}}$ prime: $g_{n}=p_{n+1}-p_{n}$. Oppermann's conjecture is a prominent unsolved problem in pure mathematics concerning prime gaps. Despite verification for numerous primes, a general proof remains elusive. If true, the conjecture implies that prime gaps grow at a rate bounded by $g_{n}<{\sqrt {p_{n}}}$. We examine the ratio of Chebyshev functions for consecutive primes, $\frac{\theta(p_{n+1})}{\theta(p_{n})}$, and compare it to the square root of their ratio, $\sqrt {\frac{p_{n+1}}{p_{n}}}$. Assuming this inequality holds for primes larger than $10^{8}$, we demonstrate the truth of Oppermann's conjecture. For sufficiently large $n$, this inequality guarantees that $g_{n}<{\sqrt {p_{n}}}$ for all primes beyond a certain point. Our proof also validates Andrica's, Legendre's, and Brocard's conjectures for primes exceeding a specific threshold.

Steel surface protection with hard coatings is essential in the metalworking industry, yet developing high-performance hard coatings still remains a challenge. Quaternary nitride coatings, particularly TiAlSiN, have been extensively studied, but commercial TiAlSiN coatings vary widely, and there is a lack of consistent data. This study presents findings on the development and evaluation of TiAlSiN and TiAlSiN/TiN thin films, with an 800 nm thick TiAlSiN top coating and a 100 nm thick TiN mid-coating. The films were deposited on C120 tool steel discs via reactive DC magnetron sputtering. Ti and TiAlSi 75–20–5 (at.%) disc-shaped targets (50.8 mm diameter × 6.3 mm thickness), fabricated by our team through spark plasma sintering, were used for the sputtering process. Coatings were grown on smooth steel substrates heated to 300 °C, resulting in a uniform micro-structure with nanoparticles of globular (TiN) or pyramidal shape (TiAlSiN), as evidenced by SEM analysis. Nanoindentation tests showed superior mechanical properties for all coatings compared to the steel substrate. Micro-scratch tests indicated better scratch resistance for TiAlSiN/TiN bilayer (BL) coatings than for TiAlSiN single-layer (SL) coatings. Electrochemical impedance spectroscopy tests in a 3.5 wt.% NaCl solution revealed that the BL coatings demonstrated superior corrosion resistance compared to the SL coatings, even after thermal aging at 800 °C for 1 hour. The superior properties of the synthesized TiAlSiN/TiN films recommend them as protective coatings for tool steel surfaces.

Background: Attendance to neonatal follow-up programs (NFU) presents as a significant factor associated with long-term outcome of high-risk infants. Few studies have focused on attrition or loss to follow up particularly during COVID-19 pandemic. Methods: In this retrospective observational study, data from 1137 high-risk neonates who participated in a hospital NFU program were collected (573 before and 564 after the onset of COVID-19 pandemic). The study sample was grouped to: G1 (N=831) who maintained participation in the program, G2 (N=196) who discontinued, and G3 (N=110) who never visited the outpatient clinics. Data was obtained from the hospital's Systems Applications and Products Software, and a structured questionnaire, answered by parents of newborns either discontinuing (G2) or not attending (G3) the NFU program, through a telephone contact.Results: The most frequently reported reason for discontinuance before the onset of the pandemic was the parents' perception that it was not necessary to maintain participation in the program (44.12%). During the COVID-19 pandemic, provider-related barriers to maintaining hospital access, inability to provide high-quality services (37.14%), and feelings of fear and insecurity (18.5%), emerged as factors for non-attendance. Citizenship and morbidity (RDS, sepsis, NEC, jaundice) acted as incentives to join the NFU program during both study periods. Multiple regression analysis showed that multiple gestation infants had higher odds for maintaining participation during the COVID-19 period (OR, 4.04; CI, 1.09-14.9). Conclusion: Understanding the potential impact of COVID-19 and the transformative changes in NFU clinics is crucial to apply compliance strategies. Removing barriers to maintain family participation can lead to increased attendance rates.
