Comparison of Recent Shear Capacity Models Against Experimental and Simulation Databases of Ultra-High-Performance Concrete Beams
Authors: Ross Brandon , Tarawneh Ahmad , Naser M.Z. , Ferche Anca C. , Diab Amjad , Craig Deanna
Published: October 2024

This paper reports on an evaluation of two models for calculating the shear strength of prestressed ul¬tra-high-performance concrete (UHPC) beams. Cal¬culations from these models, referred to as the eCPCI and FHWA (Federal Highway Administration) models, were compared to a database of experimental test results compiled from the literature. Identifying comparable UHPC material properties from the published literature was a challenge because different testing programs used different material tests. Accordingly, UHPC localized tensile strength was estimated based on the available data and approximate ratios. In addition to the experi¬mental database, a machine-learning prediction model was developed to generate a simulation database used for further evaluation of the eCPCI and FHWA models. On average, the FHWA model resulted in shear capacity estimates that were 17% lower than the eCPCI method. However, the analyses show that shear strength predic¬tions from both the FHWA and eCPCI models were typ¬ically conservative relative to data from the experimental and simulated databases. In addition, both models were observed to produce less-accurate estimates for larg¬er-sized specimens than for smaller specimens.

Project Spotlight: Nashville courthouse clears the air using special concrete
Authors: Nichols Mason
Published: October 2024

Innovation and resilience are at the heart of the Fred D. Thompson U.S. Courthouse and Federal Building, a structure that leverages precast concrete to perfectly marry classic appeal with a contemporary aesthetic. For the Nashville, Tenn., courthouse, the U.S. General Services Administration sought a design approach reflective of the U.S. justice system. Thanks to the use of precast concrete panels, columns, and box beams, this was accomplished in several ways. The building’s facade is symmetrical, reflecting the need for balance in the courtroom. The panels are white, emphasizing the court system’s ideal state as a conveyor of truth and balance in U.S. society and government, and the building’s stately presence is a reminder of U.S. stability, a characteristic shared with the precast concrete elements that made it possible. GATE Precast was the precast producer for the project.
Higher-order stochastic averaging for investigating a vehicle suspension system with nonlinear damping and stiffness
Authors: Anh Nguyen Dong , Linh Nguyen Ngoc , Ngoc Nguyen Duc , Manh Nguyen Van
Published: October 2024

The paper deals with a quarter-car model with nonlinear damping and stiffness under white noise base excitation using the higher-order stochastic averaging method for analyzing approximate responses. Recently, a novel higher-order averaging procedure has been developed to find analytically the first-, second-, and third-order stationary joint probability density functions (PDF) of amplitude and full phase by solving the corresponding Fokker-Planck-Kolmogorov (FPK) equation, and it will be extended to the nonlinear quarter-car model. Accordingly, the mean-square responses such as the displacement, and velocity of the sprung mass can be obtained analytically. The influences of excitation intensity on the dynamic responses, as well as the variations of linear and nonlinear damping, are analyzed. A very satisfactory agreement is found between the accuracy of the solutions corresponding to higher-order stochastic averaging and that of Monte Carlo simulation.
Magnificat: an exploration of sacred music in the United States
Authors: Benda Jacob
Published: October 2024

The landscape of sacred music in the United States is broad and wide and cannot be neatly defined into a collective approach or style. The boundaries of Roman Catholic sacred music in America have been expanding further and further since the establishment of the liturgical reforms outlined by the Second Vatican Council’s Constitution on the Sacred Liturgy (Sacrosanctum Concilium), and it was through this new sense of “freedom” that alternative styles of liturgical music emerged during the past 60 years. Interestingly, the state of Minnesota was at the center of this liturgical music revolution as composers associated with the University of St. Thomas, St. John’s University, and St. Catherine’s University composed a large portion of ‘new’ liturgical music. This article explores the musical trends of the past 60 years in the United States, and offers suggestions regarding the practice and education of sacred music in America and beyond.

Does Fear of Negative Evaluation Itself Cause Academic Procrastination?: Focusing on the Moderating Effect of Social Anxiety
Authors:   Gachon University, Kim Sang yeol , Seo Eun Hee ,   Gachon University
Published: October 2024

This study focused on the inconsistent relationship between the fear of negative evaluation and academic procrastination in previous studies and assumed that there may be a moderating variable between the two variables. Therefore, this study aimed to verify the moderating effect of social anxiety on the relationship between the fear of negative evaluation and academic procrastination. For this purpose, a questionnaire was administered to 323 college students from 41 universities in Korea, and the data were analysed. The result showed that the fear of negative evaluation and social anxiety had significant influences on academic procrastination. The moderating effect of social anxiety on the relationship between the fear of negative evaluation and academic procrastination was significant. In particular, when social anxiety was low, the relationship between the fear of negative evaluation and academic procrastination was not significant.

Social competence is one of the basic key competencies of educational leaders, where the research aimed at targeted facilitation is absent. Thus, the study aims to verify the changes in the development of social competence and coping self-efficacy of future educational leaders within two courses (one-term course at university vs. one-year course at an educational non-profit institution) (university students of teaching branches: NUMB = 13; AMage = 27.8; SDage = 7.4; 29.4% men vs. participants of the educational institution: NNGO = 14; AMage = 38.6; SDage = 7.8; 21% men). The Coping Self-Efficacy Scale, CSES) assessed the overall level of coping self-efficacy and its four factors, and the Inventory of Social Competence (ISK – K) assessed four social competencies. Results showed a significant increase of low practical significance over time (pretest vs. retest) in the level of social orientation (in ISK – K) and an increase of medium significance in overall self-efficacy and in the ability to use strategies focused on problems and unpleasant emotions and thoughts (in CSES) among university students. After completion of the course, NGO participants increased (with a low practical significance) their SK-K levels of offensiveness and self-control and their CSES self-efficacy and ability to use strategies focused on problems and unpleasant emotions and thoughts. There were no significant differences between overall levels in the two courses. The study offers possible implications of social competence facilitation in the context of educational leader formation at Slovak schools.

Published: October 2024

Mobile devices bring new solutions and opportunities as well as challenges for family relationships. We examined the association between parents’ attitudes towards preschool children’s mobile device usage habits (PAT) and parent–child relationship (PCRI) and tested whether this association is dependent on parent characteristics. The results showed that there is no correlation between the total scores of PAT and PCRI. On the other hand, PCRI was moderately correlated with three subscales of PAT (the subscales of Distraction, Control, and Information). Further, we found out the potential influence of parent sex on parental attitude and parental educational level on the parent-child relationship.

This study aimed to evaluate Polish university students’ health literacy (HL) in the context of school and out-of-school health education and socialisation. The survey was conducted in two Polish universities between March 2023 and April 2024 using an online questionnaire. The research revealed the correlation between the HL of Polish university students and both school and non-school health education and socialisation, with a higher positive association with non-school health socialisation. Furthermore, the study revealed statistically significant differences between the general HL of Polish university students and the sources of health education. The lack of health education at school seemed to be the most significant differentiating factor. Health-literate students mean health-literate citizens. Achieving this goal should be at the forefront of future policy decisions. Therefore, implementing health education and health promotion throughout the school system (including higher education) should be a priority today.

The paper aims to study and analyse smart technologies’ impact on students’ motivation to learn foreign languages. The testing method (SLAM), the interview method, the method of expert evaluations, the t-test, factor analysis, and Cronbach’s alpha reliability coefficient were used. The control group mainly shows instrumental motivation based on the need to learn the language to solve practical tasks, such as professional activities or travel. The experimental group shows an integrative motivation to learn the language to understand the cultural context and communicate with native speakers. It was established that smart technologies significantly increase overall academic productivity, promote easier assimilation of educational material, and enhance interest in learning a foreign language.

Efficient and Fair Healthcare Rationing
Authors: Aziz Haris , Brandl Florian
Published: October 2024

The rationing of healthcare resources has emerged as an important issue, which has been discussed by medical experts, policy-makers, and the general public. We consider a rationing problem where medical units are to be allocated to patients. Each unit is reserved for one of several categories, and each category has a priority ranking over the patients. We present a class of allocation rules that respect the priorities, comply with the eligibility requirements, allocate the largest feasible number of units, and do not penalize agents for rising in the priority ranking of a category. The rules characterize all possible allocations that satisfy the first three properties and are polynomial-time computable.
Inverting Cryptographic Hash Functions via Cube-and-Conquer
Authors: Zaikin Oleg
Published: October 2024

MD4 and MD5 are fundamental cryptographic hash functions proposed in the early 1990s. MD4 consists of 48 steps and produces a 128-bit hash given a message of arbitrary finite size. MD5 is a more secure 64-step extension of MD4. Both MD4 and MD5 are vulnerable to practical collision attacks, yet it is still not realistic to invert them, i.e., to find a message given a hash. In 2007, the 39-step version of MD4 was inverted by reducing to SAT and applying a CDCL solver along with the so-called Dobbertin’s constraints. As for MD5, in 2012 its 28-step version was inverted via a CDCL solver for one specified hash without adding any extra constraints. In this study, Cube-and-Conquer (a combination of CDCL and lookahead) is applied to invert step-reduced versions of MD4 and MD5. For this purpose, two algorithms are proposed. The first one generates inverse problems for MD4 by gradually modifying the Dobbertin’s constraints. The second algorithm tries the cubing phase of Cube-and-Conquer with different cutoff thresholds to find the one with the minimum runtime estimate of the conquer phase. This algorithm operates in two modes: (i) estimating the hardness of a given propositional Boolean formula; (ii) incomplete SAT solving of a given satisfiable propositional Boolean formula. While the first algorithm is focused on inverting step-reduced MD4, the second one is not area-specific and is therefore applicable to a variety of classes of hard SAT instances. In this study, 40-, 41-, 42-, and 43-step MD4 are inverted for the first time via the first algorithm and the estimating mode of the second algorithm. Also, 28-step MD5 is inverted for four hashes via the incomplete SAT solving mode of the second algorithm. For three hashes out of them, it is done for the first time.

Published: October 2024

A twelve year‐old‐girl with idiopathic partial epilepsy with secondary generalization, developed acute psychosis 10 days after the administration of levetiracetam. The patient was already on sodium valproate, and levetiracetam was given as add on therapy. A final dosage of 60 mg/kg was used. Complete seizure control was achieved but the patient developed hallucinations, agitation and self‐harming behaviour, as well as poor social contact. The psychotic behavior resolved completely soon after the discontinuation of levetiracetam.
Silent Questions: (Not) Talking about Dying in the Pearl River Delta
Authors: Menzfeld Mira
Published: October 2024

This Field Notes contribution describes the difficulty of confronting the topic of dying in conversations with terminally ill persons in the Pearl River Delta region in the People’s Republic of China (PRC), and how the ethnographer responded to this difficulty in a way she did not expect. While there is probably no ideal conversation starter for this subject anywhere in the world, bringing up the topic of approaching death is particularly challenging in China. First, it is considered impolite and harmful to communicate to a person directly that she is dying. Second, a terminal diagnosis is not necessarily received as though fatality is an inevitable consequence. After more than a few instances of feeling awkward and unequipped to talk to terminally ill persons during fieldwork, the author came to a realisation: encouraging those who are dying to communicate their experience of dying is not about finding a suitable opening line; rather, it is about silent presence, which may be the best invitation to speak.

Published: October 2024

This matter concerns an attempt by the employer to interdict unidentified workers in the cause of a strike that turned violent and resulted in damage to the property of the employer. The issue before the Constitutional Court was, can an employer facing unlawful conduct committed during a protected strike interdict employees participating in that strike without linking each employee to the unlawful conduct? This note will do as Theron J did in starting the judgment by discussing the facts of the case, going into detail about what the Labour Court and the Labour Appeal Court found. The note will also engage in a detailed discussion about the judgment of Theron J.

Familiarity Effect in the Perception of Handwriting: Evaluating in-group/out-group effect among readers of the Latin script
Authors: Mangas Afonso Hector , Keizer Anouk , Biľak Peter , Beier Sofie
Published: October 2024

There is much evidence that familiarity can affect perception of stimuli, with items that are familiar to the individual being preferred and better remembered. Previous research has also shown that familiarity with a typeface increases preference for it, but no studies have evaluated the impact of familiarity in relation to the affect towards handwritten text. For the present study, a two-part experiment (N = 422) was designed to measure how contemporary users of the Latin script perceive handwritten text. The first section was designed to collect specimens of the participants’ handwriting. The second, which was adapted to each participant’s handwriting style, measured implicit judgments of certain familiar letter shapes against unfamiliar ones. Results show that familiarity positively influences the extent to which one judges the friendliness and trustworthiness of handwritten text. Furthermore, the greater the similarity to how one writes a letterform, the greater the observed effect in terms of perceived friendliness. These findings suggest that people have an implicit bias towards handwriting that looks like their own.

The syntaxonomic diversity of meadows and mires in the 3 sites studied within the axial part of the Polar Urals includes 5 associations and 3 subassociations, which belong to 3 classes of phytosociological classification. 4 associations and 3 subassociations are described for the first time. One association (Carici lachenalii–Harrimanelletum hypnoidis ass. nov.) and 2 subassociations (C.l.–H.h. typicum subass. nov. and C.l.–H.h. phyllodocetosum coer uleae subass. nov.) we assigned to the class Salicetea herbaceae Br.-Bl. 1948. Class Mulgedio–Aconitetea Hadač et Klika in Klika et Hadač 1944 is represented by 3 associations: Hylocomiastro pyrenaici–Luzuletum frigidae ass. nov., Aconito septentrionalis–Salicetum lanatae Sekretareva 2011, including a new subassociation (A.s.–S.l. alchemilletosum obtusae subass. nov.) and Trientalo europaeae–Alnetum fruticosae ass. nov. Class Scheuchzerio palustris–Caricetea fuscae Tx. 1937 is represented by 1 association (Carici rariflorae–Sphagnetum squarrosi ass. nov.). Certain increase in species richness was recorded in syntaxa located in the northern part of the Polar Urals, it is caused by an increase in the diversity of mosses and lichens and the appearance of several arctic and hypoarctic species of vascular plants which were absent in the southern part. Such increase is often observed on the border of subzones or belts, where southern species are still present and some northern species have appeared. Number of distinguished syntaxa was the same in all localities.

Supercritical fluid technology was used to obtain bioactive substances from leaves of Ribes fragrans Pallas. Supercritical fluid technology showed the strongest extractive effect, which helped to extract the maximum amount of bioactive substances. Several experimental conditions were investigated in the pressure range 50–300 bar, with the used volume of co-solvent ethanol in the amount of 2.5 % in the liquid phase at a temperature in the range of 31–70°C. The most effective extraction conditions were: pressure 200 Bar and temperature 55°C. The CO2-extract of leaves of R. fragrans contain various polyphenolic compounds and compounds of other chemical groups with valuable biological activity. For the first time, the metabolome of supercritical extracts of R. fragrans leaves was studied in this research. Using the method of supercritical extraction of plant matrices with the method of tandem mass spectrometry, it was possible to tentatively identify 79 bioactive compounds, of which 53 compounds are of polyphenol group. 20 chemical compounds from polyphenol group and 12 chemical compounds from other chemical groups were identified for the first time in genus Ribes.

The plants of the Zygophyllaceae family are often considered to be capable of symbiotic atmosphere nitrogen fixation, forming rhizobial nodules similar to those of Fabaceae and Urticaceae. In four species of Zygophyllaceae and the related Peganum harmala (hereafter called Z-plants), collected in Dzungarian deserts (Kazakhstan), we analyzed the prokaryotic component of the root microbiome and the 15N and 13C content in the leaves of these Z-plants compared with neighboring dicots belonging to other families (R-plants). Among all studied Zygophyllum fabago root samples only one was found to have the root nodule, however the microbiome of this sample was similar to that found in other Z. fabago root samples where nodulation was not observed. If compared to Z-plants, the R-plants had a significantly higher relative abundance of bacteria of genera Glycomyces, Massilia and Streptomyces, while the Z-plants had a higher relative abundance of the representatives of genera Actinomadura, Nocardia and Pseudonocardia. Unidentified representatives of the family Rhizobiaceae were present in some of R and Z plants, being most abundant in soil samples. On average, the Z- and the R-plants did not differ in their δ13С and δ15N. Overall, the results do not allow us to consider the studied Zygophyllaceae plants as species with effective atmospheric nitrogen fixation due to rhizobial symbiosis – a characteristic feature of the most legumes.
An Analysis of Student Satisfaction and its Relationship with Academic and Social Factors in University Dropout
Authors: Esteban Maria , Bernardo Ana B. , Blanco Elena , Oserin Palmira
Published: October 2024

Over the last 50 years, Higher Education has experienced significant development, which has been associated with challenges that have yet to be solved. In this sense, university dropout is a global phenomenon that worries universities all over the world. Many research studies describe the possible causes of this phenomenon, but the most interesting are those that, due to their predictive potential, have the possibility of preventing it. The aim of this article is to study how important students perceive the different reasons for dropout in relation to the idea of abandoning the degree. For this purpose, the Spanish version of the Questionnaire of Motives for Higher Education Dropout (QMA_es; Almeida et al., 2019) was applied to a sample of 927 first- and second-year university students. These data have been processed using educational data mining (EDM) techniques, obtaining a decision tree that correctly classifies the sample in 81.1%. The results show that variables related to student satisfaction (satisfaction with academic choice, satisfaction with performance, and satisfaction with the financial situation) and to the academic and social environments play a predominant role in the approach to dropout, above other institutional, financial, and wellbeing variables.
Mathematical Modelling from a Semiotic-Cognitive Approach
Authors: Ledezma Carlos
Published: October 2024

Mathematical modelling has acquired relevance in different fields at an international level, both in education and research. This article states that, throughout the construction of the theoretical corpus of this mathematical process and competency – among others – two big issues have occurred: one of terminological nature since the definitions surrounding modelling have varied, and other of representational nature since different representations have been proposed to explain modelling as a cyclical process. These two issues occur mainly due to the diversity of positions on how modelling is understood and how this process is tried to be explained. To address the terminological issue, a position was adopted on the terminology surrounding modelling in Mathematics Education, based on the main theoretical developments of ICTMA Community. To address the representational issue, a modelling cycle from a semiotic-cognitive approach that represents this process in a non-set way is proposed, that is, without a strict separation between «real world» and «mathematical world». In this way, a proposal aligned with a system of theoretical principles (terminology and structure), a methodology (modelling cycle), and sketches of research questions (for future theoretical and empirical developments) is presented to address both issues.

Se analizaron 312 artículos de Scopus y WoS, y con Atlas.ti se realizó la codificación temática y el mapeo de conexiones.  Un primer resultado es que los autores más relevantes que han usado esos referentes teóricos son Font, Breda y Godino, y que España es el núcleo de una red de colaboración con países de América latina. Un segundo resultado es que una de las líneas de avance es buscar la integración de ambos modelos para determinar conocimientos y competencias que necesita el profesorado para incorporar la tecnología en el aula, sea en general o bien para contenidos específicos. El análisis señala áreas emergentes a investigar, como los conocimientos y competencias necesarias para la integración de la tecnología en el proceso de enseñanza y aprendizaje de nociones específicas.

The Suku Anak Dalam (SAD) community in Sumatra, Indonesia, faced unique educational challenges influenced by cultural, social, and economic factors. This study aimed to explore and confirm the influential relationships among cultural practices, social support, economic factors, and SAD’s perceptions of religious education. A total of 356 literate SAD from some regions in Sumatra were sampled. Utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM), data were collected through a structured questionnaire translated into the local language. The results revealed that cultural practices positively impacted SAD’s perceptions of religious education (H1, t=7.550, p=0.000) and significantly enhanced social support (H4, t=3.870, p=0.000). Social support positively influenced perceptions of religious education (H2, t=4.880, p=0.000), while economic factors had a strong positive effect on both perceptions of religious education (H3, t=9.119, p=0.000) and social support (H5, t=31.108, p=0.000). These findings highlight the necessity of integrating cultural, social, and economic aspects in educational policies for the SAD community. The study's novelty lies in its structural model, offering deep insights into religious education perceptions. Future research should explore similar dynamics in other indigenous communities using longitudinal and qualitative methods.

Desde 2017, el sistema escolar chileno ha estado en proceso de reforma derivado del proyecto de la Nueva Educación Pública (NEP). Este estudio ha analizado las responsabilidades del nuevo nivel de administración intermedio, llamado Servicios Locales de Educación Pública (SLEP), según lo declarado en diversos documentos gubernamentales. Se realizó un estudio mixto de revisión documental. El corpus textual estuvo compuesto por la Ley N° 21.040, la Primera Estrategia Nacional de Educación Pública, y los tres documentos que concentran los Estándares Indicativos de Desempeño a nivel General, de Educación Parvularia y de Educación Media Técnico-Profesional. El análisis de contenido fue cualitativo, y luego, cuantitativo descriptivo para estimar frecuencias y proporción de responsabilidades en cinco dimensiones de gestión: liderazgo, pedagógica, recursos, territorio y convivencia. Los resultados identifican 114 responsabilidades, las que se encuentran sobrerrepresentadas en las dimensiones de liderazgo y gestión pedagógica, en desmedro de la dimensión convivencia, así como un desequilibrio de tareas de gestión en ausencia de mecanismos claros de rendición de cuentas. Los resultados se discuten en torno a las implicancias para la reforma del cuasi-mercado educativo chileno, y los desafíos que aún quedan para avanzar hacia un enfoque que desafíe el modelo actual de accountability.

Given the high prevalence of gender violence among adolescents and youth, research has underscored the importance of preventing it from an early age. The literature has clarified that the prevention of gender violence requires the union of the language of desire and of ethics to promote egalitarian relationships as desirable. Nevertheless, there is a need for a more in-depth and extensive analysis of the key concepts that emerge in DLG, implemented in diverse contexts to better understand their potential as a space for the prevention of gender violence. To contribute to filling this gap, this study explores key concepts of desire and ethics that adolescents surface in DLG implemented in 5 Learning Communities have in common. To that end, 26 observations in 9 different DLG groups with students aged 10-15 and 45 interviews with students and teachers were conducted. Results show one key concept of desire and ethics in these DLG: many students reject violence and peer pressure. Implications of these findings for the prevention and overcoming of gender violence are discussed.

Da polêmica aos discursos de ódio: um estudo da recepção no twitter sob a perspectiva semiolinguística / From controversy to hate speech: a study of reception on twitter from a semiolinguistic perspective
Authors: Melo Mônica Santos de Souza
Published: October 2024

Resumo: Esse artigo tem como objetivo contribuir para o estudo da recepção no âmbito da Análise do Discurso, analisando o tênue limite entre manifestações polêmicas e discursos de ódio em comentários de internautas em resposta a um vídeo publicado pelo ex-deputado Jean Wyllys, intitulado “Qual dos dois está mais próximo dos – ou segue mais os – ensinamentos deixados por Jesus nos evangelhos? Qual dos dois preserva mais os verdadeiros valores cristãos?” A partir das contribuições de Charaudeau (2008) e Barros (2015), dentre outros, procuramos analisar os comentários produzidos pelos internautas sobre essa mensagem. Por meio da diferenciação de manifestações de concordância e discordância, identificamos os casos de rejeição extrema ao locutor, os quais ultrapassam o plano da polêmica e se caracterizam como discursos de ódio, revelando, nos dados analisados, traços da chamada matriz ideológica da direita conservadora.

Abstract: This paper aims to contribute to the study of reception within the scope of Discourse Analysis, analyzing the fine line between controversial manifestations and hate speech in comments by Internet users in response to a video published by former deputy Jean Wyllys, entitled “Which of the two is closest to – or more closely following – the teachings left by Jesus in the gospels? Which of the two most preserves true Christian values?” Based on the contributions of Charaudeau (2008) and Barros (2015), among others, we seek to analyze the comments produced by Internet users on this message. Through the differentiation of expressions of agreement and disagreement, we identified cases of extreme rejection to the speaker, which go beyond the scope of the controversy and are characterized as hate speech, revealing, in the analyzed data, traces of the so-called ideological matrix of the conservative right.

Clinical profile of meconium aspiration syndrome with special reference to birth weight, gestational age and immediate outcome at tertiary care centre
Authors: Chauhan Anuya V. , Mahapatra Sunita , Khare Prarthana
Published: October 2024

Background: Meconium aspiration syndrome (MAS) is a leading cause of neonatal respiratory distress, occurring in 5% of infants born through meconium-stained amniotic fluid (MSAF). It is linked to fetal distress and can lead to significant lung complications.
Methods: A prospective study was conducted from March 2021 to February 2022 in the NICU at Civil Hospital, Ahmedabad. MAS was diagnosed based on respiratory distress in neonates born through MSAF using criteria mentioned in Cloherty and Stark’s manual of neonatal care. The clinical and demographic information was recorded on pre-structured proforma & they were categorized into mild, moderate and severe MAS according to fraction of inspired oxygen (fiO2), duration of oxygen required and associated complications.
Results: Among 110 neonates with MAS, 87% were full-term, 11% post-term, and none preterm. Most (49.09%) weighed between 2.50–2.99 kg, and 85.45% were appropriate for gestational age. Severe birth asphyxia was the most common comorbidity (30.90%), followed by septicemia and pneumothorax. HFNC was used in 57.27% of cases, while 32.72% required ventilation. The mortality rate was 10%, with pneumothorax being the leading cause of death.
Conclusion: Proper antenatal care with prevention and treatment of maternal risk factors, intrapartum assessment of foetal distress and use of proper aseptic techniques during delivery & resuscitation and then transport of the baby to referral centre help in reducing morbidity and mortality in MAS neonates. After birth, timely diagnosis and provision of proper respiratory support by assessment of the severity of distress can prevent the mortality and morbidity due to MAS.
