Published: January 2025

ABSTRACT Characterizing and predicting genetic diversity within the genus Passiflora is critical for promoting diversified strategies in genetic improvement programs. The present study aimed to characterize the morphology of pollen grains and seeds, and to infer the 2C DNA content using flow cytometry in species of the genus Passiflora with ornamental potential. For the morphological characterization of pollen grains and seeds, 11 and 12 descriptors were used, respectively. The data obtained were analyzed using ANOVA and grouped according to the Scott-Knott method. To study genetic diversity, the Mahalanobis distance matrix, and the UPGMA agglomerative method were used. For the morphological characterization of pollen and seeds, the results indicated significant differences across all descriptors. Four descriptors were particularly remarkably divergent: colpus width, equatorial axis, polar axis length, and the number of ornaments on the seeds. The species were grouped into three clusters in the dendrogram using the clustering method. 2C DNA content values demonstrated high interspecific variability, possibly due to chromosomal number and size. These results enabled the detection of genetic diversity, the significance of the biological trait values, and a better knowledge of interspecific gene interactions, all of which aid the selection of ornamental parent plants.

ABSTRACT The primary method of soybean breeding is artificial hybridization. Therefore, genitors must be carefully selected, especially given the crop’s restricted genetic base. This study aimed to quantify genetic diversity across soybean genotypes using agronomic traits and microsatellite markers and to identify promising parent combinations. We evaluated 26 soybean genotypes in the greenhouse and characterized 11 agronomic traits. Polymorphism for five microsatellite markers was assessed on a 2% agarose gel. Univariate and multivariate analyses were used to detect genetic variability and determine genetic diversity. All agronomic traits, except plant height at maturity, showed genetic variability. The genotypic coefficients of determination ranged from 34.41% to 69.81%. The genetic dissimilarity for agronomic traits ranged from 2.49 to 42.77, enabling the formation of five, eight, and seven groups using the UPGMA, farthest neighbor, and Tocher methods, respectively. The dissimilarity obtained by the microsatellites ranged from 0.11 to 0.93, allowing the genotypes to be divided into seven, eight, and four groups, respectively, using the UPGMA, farthest neighbor, and Tocher methods. The vegetative and total cycles were the traits that contributed most to genetic diversity. The data analysis identified Emgopa 316 x NS 7200, Emgopa 316 x UFUS (7415 x MG / BR 46 Conquista), TMG 801 x NS 7200, and TMG 801 x BRSGO Luziânia hybrids as promising for early cycle, grain yield, and disease resistance.

Published: January 2025

Frailty is a significant risk factor for adverse outcomes in elderly surgical patients. Gait speed assessment is a new tool recently used to stratify risk for these pre-operative adverse outcomes. In this prospective study of 392 frail elderly patients undergoing abdominal surgery, we investigated the predictive value of preoperative gait speed for postoperative outcomes. Patients were divided into two groups based on their 6-meter gait speed: normal (≥0.8 m/s, n=184) and slow (<0.8 m/s, n=208). The slow group was older, had more comorbidities, and higher American Society of Anesthesiologists (ASA) grades (P<0.05). They also had significantly higher rates of 30-day overall complications (38.9 vs 18.5%, P<0.01), severe complications (12.0 vs 4.3%, P<0.01), and 1-year mortality (15.4 vs 6.5%, P=0.008) compared to the normal group. Pulmonary infection, wound infection, and delirium were the most common complications. Multivariate logistic regression confirmed slow gait speed as an independent risk factor for 30-day complications (OR=2.38, 95%CI: 1.41-4.01) and 1-year mortality (OR=2.19, 95%CI: 1.07-4.48). Our findings demonstrated that preoperative 6-meter gait speed effectively predicted short-term complications and mid-term mortality in frail elderly patients undergoing abdominal surgery. This suggests the need for individualized perioperative management strategies for high-risk patients with slow gait speed to potentially improve their prognosis.

ABSTRACT In the current study, polypropylene and steel hybrid fiber reinforced self-compacting concrete was analyzed with and without the introduction of carbon nanotubes. A range of workability and hardened properties studies was performed along with the adsorption characteristics. Three different weight fractions including 15, 20, 25 kg/m3 for polypropylene fiber and 3,6,9 kg/m3 of steel fibres were individually and combinedly added. Also, with a fixed volume of 0.4% of carbon nanotubes, the behaviour of SCC was analyzed. To evaluate the fresh properties of Hybrid Fiber Reinforced Self-Compacting Concrete (HFRSCC), V-Funnel, slump-flow and L-box tests were performed. Result reveals that steel fiber and hybrid fiber added self-compacting concrete provides enhanced hardened properties than the polypropylene fiber SCC. Also, the result revealed that with the CNT incorporation, the hardened strength properties were enhanced and however the workability characteristics diminished.

Abstract Cherry tomato (Solanum lycopersicum var. cerasiforme) cultivation has become a very profitable option due to its high added value. Therefore, using technologies for water control and soil conditioners is a possible way to increase profitability for producers. Thus, the objective of the present study was to assess the effects of irrigation and poultry litter biochar on the vegetative growth of cherry tomato, ‘Carolina’ cultivar. The experiment was conducted in a semi-protected greenhouse of UAEA/UFCG campus in Campina Grande, PB, Brazil, using a completely randomized design, in a 4 x 4 factorial scheme with 3 replicates and in split plots. The factors studied were four levels of irrigation (70, 80, 90 and 100% of soil field capacity) and four doses of poultry litter biochar (0, 4, 8 and 12 t.ha-1). In the evaluation of plant height in relation to irrigation depth, a percentage increase of 33.19% was observed between the highest and lowest irrigation depths (70% and 100% of field capacity) at the end of the experiment. Regarding stem diameter in relation to irrigation depth variation, there was an increase of 5.5 mm from 47 to 107 days after germination. Poultry litter biochar influenced stem diameter, resulting in a percentage gain of 6.91% between the lowest and highest doses (0 and 12 t.ha-1). For leaf area, there was a percentage increase of 18.1% when comparing the lowest and highest irrigation depths (70% and 100% of field capacity).
A utopia camponesa de Chayanov e perspectivas contemporâneas de uma sociedade mais justa e ecológica
Authors: Moruzzi Marques Paulo Eduardo , Alves José Caio Quadrado
Published: January 2025

Resumo Para o sociólogo Norbert Elias, a emergência do gênero literário utópico, inaugurado por Thomas More no século XVI, constitui um importante indício de transformação do mundo moderno. Desde então, as obras utópicas expressam um aumento crescente das reflexões sobre o papel do Estado. Trata-se de conceber um modelo de organização social fundamentado em princípios morais aceitos como legítimos. O pensamento de Alexander Chayanov é representativo dessas reflexões, ao idealizar uma utopia camponesa como perspectiva de mundo justo, com princípios precursores de justiça ecológica. Esse tipo de utopia anima, na contemporaneidade, escolhas e ações como aquelas do Movimento dos Trabalhadores Rurais Sem Terra (MST) com vistas à democratização do acesso à terra. A concepção de assentamento “Comuna da Terra”, preconizada pelo MST no estado de São Paulo, apresenta muitos pontos de afinidade com a utopia de Chayanov. O estudo de casos dessa natureza é promissor para discutir a construção de orientações transformadoras no Brasil.

ABSTRACT Objective: To determine the prevalence of possible sleep and awake bruxism and its related risk factors in children with Congenital Zika Virus Syndrome. Material and Methods: The case group consists of 20 children with congenital Zika, age range from S to 6 years old, and the control group consists of 120 regular children of the same age group. A questionnaire was used to assess bruxism and associate possible risk factors such as medications, systemic disorders, and sleep relationships, and a validated Oral Behaviors Checklist (OBC) was applied. Absolute and percentage frequencies of each outcome variable and mean and standard deviation of each item of the OBC questionnaire were calculated, respectively, compared between case and control groups using Fisher’s exact or Pearson’s chi-square and Mann-Whitney tests. Results: Only 25% of the children with microcephaly do not present swallowing difficulty, significantly lower compared to the 95.8% of the children in the control group who do not (p<0.001). The occurrence of bruxism was significantly higher in the case group (47.4%) compared to the control group (10.2%). In addition, 89.8% of children did not grind their teeth in the control group, compared to only 52.6% in the case group. There was a statistically significant difference between the case and control group (p<0.001). Conclusion: Dysphagia, feeding routes, and reflux in children with cerebral palsy are risk factors for possible awake bruxism, and children with congenital Zika virus syndrome showed a prevalence for possible bruxism compared to regular children.

ABSTRACT Objective: To develop a questionnaire to describe endodontic treatments in primary teeth among Brazilian dental practitioners, focused on face and content validity (FCV). Material and Methods: An online validation process involved ten judges (panel of experts) and 32 dental practitioners (pre-test). The initial questionnaire (33 items) was developed after a literature review and divided into two parts: 7 questions for characterizing Brazilian dental practitioners (Part 1) and 26 questions for characterizing the endodontic treatment in primary teeth carried out by them (Part 2). The questionnaire was assessed for appearance, comprehension, and relevance using a 4-point Likert scale. Validity was achieved when the Validity Index was equal to or greater than 80% (0.8), considering responses 3 or 4 acceptable. Results: Two rounds were necessary for all items of the data collection instrument to be validated. The Validity Index for the entire instrument was established at 0.97 among the experts and 0.9S among the pre-test participants. The appearance, comprehension, and relevance criteria within the panel of experts achieved Validity Indices of 0.94, 0.97, and 0.99, respectively. The pre-test participants’ values were 0.97, 0.94, and 0.94, respectively. The approximate response time for the data collection instrument ranged between 5-6 minutes. Within the expert panel, 70% of the judges rated the difficulty of filling it out as "easy." Among the pre-test participants, 56.3% judged it "very easy." Conclusion: After this validation process, the questionnaire has acceptable face and content validity and is uncomplicated and quick to fill out.

ABSTRACT Objective: To assess the influence of social support, smoking, and alcohol use on the oral health-related quality of life (OHRQoL) of pregnant women. Material and Methods: A cross-sectional study was conducted on a random sample of 256 pregnant women at a public healthcare service in southern Brazil. OHRQoL was measured using the Oral Health Impact Profile (OHIP-14) questionnaire. A semi-structured questionnaire was administered to collect demographic, socioeconomic, social support, and deleterious habits data. Clinical examinations were performed to diagnose dental caries (DMFT index) and gingivitis (marginal gingival bleeding). A Poisson regression model was used to investigate the influence of pregnant’ characteristics on OHRQoL. With this approach, we calculated rate ratio (RR) and 95% confidence intervals (95% CI). Results: The mean overall OHIP-14 score in the sample was 9.74 (SD=9.00). Pregnant women who presented poor social support reported the worst OHRQoL. Regarding deleterious habits, women who drank alcohol (RR=1.18; IC 95%: 1.05-1.33) and smoked (RR=1.20; 95% IC: 1.07-1.35) during pregnancy had higher means in OHIP-14. In addition, older and non-white women who presented untreated dental caries, ≥15% of marginal gingival bleeding, and low household income also reported worse OHRQoL. Conclusion: Our findings suggest that low support social and poor habits during pregnancy influence women’s OHRQoL.

Published: January 2025

Resumo A transformação do tabagismo em problema de saúde pública nas últimas décadas dialoga com noções contemporâneas importantes para a biomedicina e para a saúde coletiva, tais como a ideia de medicina preventiva, os debates sobre sentidos e práticas de risco, e mesmo o tema da aversão como estratégia de comunicação em saúde, seus alcances e limitações. Tais questões convergem com um tema importante para o campo da Antropologia da Saúde, que diz respeito às distâncias e aos embates entre o que é preconizado, a partir da biomedicina, como itinerários terapêuticos para o tratamento do tabagismo e as práticas e expectativas de pessoas tabagistas que pretendem parar de fumar. Ao mesmo tempo, recentemente o cigarro eletrônico tem ampliado sua presença no Brasil, seguindo tendência que parece ser mundial. Estima-se que quase 20% das/os jovens utiliza ou já utilizou o artefato, enquanto o uso do cigarro comum parece decrescer a cada ano. O presente artigo visa discutir, a partir de revisão bibliográfica e documental, bem como de elementos produzidos a partir de trabalho de campo, a entrada dos chamados cigarros eletrônicos no que denominamos dispositivo do tabagismo.

Abstract Adolescent suicide has increased in recent years, representing a global concern. Schools provide a conducive environment for identifying emotional distress and implementing actions aimed at promoting mental health and preventing suicidal behavior. Thus, this study aims to develop and validate a simulation-based teaching script for school community professionals on suicide prevention. The method involved developing and validating a simulation-based teaching script, a pedagogical approach designed to build specific skills among education professionals. To develop the script, a review of both national and international scientific literature on suicide prevention in schools was carried out. Experts in simulation and suicide prevention were invited to validate the script, selected through the Lattes Platform and the snowball sampling technique. Data collection was conducted by sending invitations via email with a hyperlink to the Research Electronic Data Capture form. Data were processed and analyzed using the STATA® Statistical Software. Descriptive statistical analysis, the content validity index (CVI), and Gwet’s First-order Agreement Coefficient (AC1) were used. The script achieved acceptability, agreement, and reliability criteria in the expert validation. This study provides a freely available script that can be used for simulation-based teaching, contributing to the ongoing education of school community professionals on mental health promotion and suicide prevention. It is recommended that future studies assess the script’s effects on professionals’ self-confidence.

Resumo Este estudo visou avaliar parâmetros de fabricação e seu impacto na qualidade da colagem de elementos de MLC. Foram realizadas três etapas de pesquisa com madeiras de Eucalipto grandis e Pinus elliottii, usando diferentes adesivos, analisando a porcentagem de delaminação e da resistência ao cisalhamento das linhas de cola. Foram testadas diferentes pressões de colagem com adesivos comerciais, quantificando os modos de ruptura na zona de colagem, diferentes proporções de adesivo natural nos elementos de MLC e diferentes espessuras das lamelas com um adesivo poliuretano bicomponente. Resultados indicaram que pressões de 0,7 MPa para o Pinus e 1,2 MPa para o Eucalipto estavam em conformidade com a norma brasileira. Diferenças significativas foram observadas na resistência ao cisalhamento entre lamelas externas e internas do Pinus. O adesivo natural demonstrou boa resistência ao cisalhamento, mas problemas na delaminação. A espessura de 3,5 cm apresentou melhor qualidade de colagem. As recomendações da NBR 7190-6 se mostraram eficazes no controle da qualidade da colagem de elementos de MLC.

Published: January 2025

Resumo Neste estudo, investigou-se o efeito da incorporação de fibras de polipropileno (FP) no concreto de alta resistência (CAR) em temperaturas elevadas, analisando possíveis lascamentos explosivos, resistência à compressão residual, módulo de elasticidade estático, resistência à tração, absorção de água, perda de massa, resistividade elétrica, velocidade de pulso ultrassônico e microestrutura, utilizando microscopia eletrônica de varredura (MEV). Uma série de ensaios foi realizada em corpos de prova cilíndricos sob aquecimento progressivo de 25 °C a 750 °C a uma taxa constante de 1 °C/min, mantendo a temperatura por 60 minutos e, em seguida, resfriando a 1 °C/min. Posteriormente, diversos ensaios foram realizados. Os resultados revelaram a ausência de lascamentos explosivos em qualquer um dos testes. Indicaram ainda que a adição de FP melhorou a resistência à compressão residual e resistividade elétrica do CAR (até 500 °C) e resistência à tração e compacidade (até 250 °C). Em temperaturas mais elevadas (750 °C), a inclusão de FP causou o desenvolvimento de canais e aumento de microfissuras e degradação da ligação entre a pasta de cimento e o agregado, resultando, em última análise, em uma redução na resistência à compressão.

Published: January 2025

Abstract The use of rationalized masonry in building construction is increasing due to process optimization and waste reduction, with performance linked to the quality and interaction of materials. This research analyzed the influence of the properties of mixed, industrialized, and stabilized rendering mortars applied to prisms composed of two ceramic blocks. The mortars were characterized in their fresh and hardened states, and their rheological behavior was evaluated using the squeeze-flow method on three different surfaces. The tensile bond strength of the mortars was determined, and the prisms, with and without coatings, were subjected to compression tests. The results showed that a greater mortar spread did not directly impact adhesion and revealed an increase in the compressive strength of the prisms with the application of the rendering layer, which was more pronounced in mortars with better mechanical performance, though not proportionally. In most cases, the failure mode of the prisms was ductile, accompanied by detachment of the mortar coatings. These findings contribute to the understanding of masonry performance and help mitigate issues caused by failures in rendering systems.
A site-retrieval approach for the prediction of jet-grouted parameters
Authors: Collico Stefano , Spagnoli Giovanni , Kamata Toshiyuki
Published: January 2025

Jet grouting is a commonly employed method for improving soil conditions, yet its design frequently involves uncertainties that might increase cost during construction projects. At preliminary phase design, it is common practice to infer local mechanical and geometrical prediction of jet-grouted columns from theoretical or empirical-based correlations. However, theoretical approaches often require parameters that are not typically available at this stage. Consequently, there is a growing trend towards adopting more advanced data-driven or probabilistic approaches to achieve more accurate and precise predictions. In this context, this work presents a novel preliminary data set from previous regional projects. The data set covers a wide range of soil types, and it is compiled by ten different parameters in terms of soil properties, jet-grouting system’s parameters as well as unconfined compressive strength (UCS) and column’s diameter ([Formula: see text]). Based on such information, a probabilistic approach for joint predictions of local UCS and [Formula: see text] is proposed. The method is based on an already consolidated Bayesian formulation, which combines local and most-similar site information to derive local prediction of UCS and column’s diameter and assess local data set incompleteness. Results for two different sites demonstrate that the proposed method can well predict local UCS and [Formula: see text].

Abstract : Practical learning experiences continue to be essential for students' overall development in engineering education today. However, the construction of physical laboratories is frequently hampered by logistical issues, especially in educational institutions with low funding. This study introduces a novel method of experiential learning through the use of a Virtual Simulation Machine (VSM) to simulate microcontrollers. By utilizing the latest developments in virtualization technology, the suggested approach enables students to imitate microcontroller behavior without the need for actual hardware by establishing an engaging and dynamic platform. Through the simulation of real-world situations and the interaction with virtual elements, students can develop practical abilities in circuit design, system integration, and microcontroller programming. An educational framework is used to perform a series of experimental sessions that evaluate the effectiveness of this strategy in terms of information retention, student engagement, and learning outcomes. Preliminary results indicate significant improvements in student performance and interest in microcontroller projects, confirming the effectiveness of the VSM as a teaching tool. In conclusion, this article promotes the use of virtual simulation technologies in engineering curriculum to improve the usability and effectiveness of experiential learning.

Abstract : Researcher interest in education data mining has increased significantly in a variety of sectors. The recent research works use a variety of machine learning techniques to predict students' academic success in the educational sectors. They suffer from serious drawbacks like low forecast accuracy, high processing times, and overhead. Therefore, the proposed work aims to develop a new model for projecting students' academic progress. The main goal of this paper is to develop a smart and automated system for predicting the students’ academic performance from the given students’ data. For this purpose, a novel optimization and deep l earning classification methodologies are implemented in this study. Here, the public UCI education training dataset is obtained to develop the prediction framework for forecasting students' academic achievement. The most correlated features from the preprocessed schooling dataset are chosen using the War Strategy Optimization (WStO) method to improve predicting performance. To effectively and reliably estimate the student performance rate with few wrong predictions, a classification method based on the Bi-directional Gated Recurrent Neural Network (Bi-GRNNet) is applied. The Arithmetic Operation Optimization Algorithm (AO2A) is used to correctly optimize the parameters of deep learning classifiers to guarantee minimal computing system complexity and quicker training. By using a complete performance evaluation study that takes into consideration a variety of various parameters, the output of the proposed WStO + Bi-GRNNet model is validated and analyzed. According to the findings, it is inferred that the proposed Bi-GRNNet integrated with WStO and AO2A technique performs well and provides an increased accuracy up to 99% while effectively predicting the students’ academic achievements.

Published: January 2025

This study investigates the process of policy change in tourism safety management triggered by the 'Itaewon disaster,' a social disaster that occurred during the Halloween festival. The study employs Thomas Birkland's Event-Related Policy Learning (ERPL) model by constructing a five-stage research framework and utilizes Yin's case study method for an in-depth analysis of a single case. The findings show that the event prompted a thorough assessment and reorganization of the safety management system. New policies addressed emerging issues, mobilized relevant groups, and facilitated policy changes and learning through debates and the adoption of innovative measures. Academically, this study confirms the applicability of the ERPL model to tourism policy change research and identifies critical stages in the process. Practically, it provides actionable strategies for safety and tourism policymakers to implement effective safety management policies. This analysis provides insights into the learning and change processes in policy and suggests directions for future tourism safety management policies.
The impact of tourists' ESG perception on behavioral intentions and willingness to pay additional costs: Utilizing the theory of planned behavior
Authors:   The Tourism Sciences Society Of Korea, Yang Hee-Won
Published: January 2025

The ESG (Environmental, Social, Governance), as a non-financial criterion for assessing corporate sustainability, has been gaining increasing importance. However, research on consumer behavior in the tourism sector remains significantly underexplored. This study employs the Theory of Planned Behavior (TPB) to analyze the relationship between tourists' perceptions of ESG, their behavioral intentions, and willingness to pay additional costs. Data were collected from October 1 to October 31, 2023, from tourists with a potential intention to engage in pro-ESG tourism, resulting in a total of 455 valid responses. Structural equation modeling (SEM), grounded in the TPB, was employed to analyze the impact of tourists' ESG perceptions on behavioral intentions and willingness to pay additional costs. The analysis was conducted using SPSS 26.0 and AMOS 26.0 software. The results reveal that tourists' perceptions of ESG positively affect pro-ESG tourism intentions and willingness to pay additional costs, mediated by TPB constructs. Specifically, perceptions related to the environmental and social dimensions of ESG significantly impact behavioral intentions. Moreover, these behavioral intentions meaningfully influence tourists' willingness to pay additional costs. However, perceptions of the governance dimension within ESG were found to exert a weaker effect on perceived behavioral control. These findings underscore the critical role of ESG in shaping tourist behavior and highlight the need for sustainable tourism strategies that incorporate ESG considerations. Given that tourists with high ESG awareness demonstrate a greater willingness to pay additional costs, it is essential for the tourism industry to strengthen ESG management strategies from a business perspective.
THE RIGHT TO BASIC EDUCATION AS A PRIMARY DRIVER OF TRANSFORMATION IN SOUTH AFRICA: CONSIDERING COOPERATION
Authors: Strohwald Annemarie
Published: January 2025

The South African Constitution provides expressly for the right to basic education, with a specific provision dedicated to such a right. The right to basic education is enshrined in section 29(1)(a) of the Constitution, which provides everyone with the right to a basic education. The constitutional right to basic education is viewed as a primary driver for effecting and advancing transformation in South Africa; the right to basic education is therefore considered through the lens of South Africa’s transformative constitution. In analysing the transformative potential of the right to basic education, the article considers to what extent this transformative potential has been embraced with specific reference to compulsory and free basic education. The manner in which the Constitution and the South African Schools Act provides for compulsory and basic education is considered in relation to transformation. The article examines the effect of South Africa’s history on the current education system. The role of the courts in providing content to the right is also analysed with reference to the incremental approach that has been adopted. At issue is also how we measure transformation and the availability of and access to data and information. The argument is made that cooperation and collaboration between different stakeholders and role players should be considered to be a key mechanism in advancing transformation to ensure that the transformative potential of the right to basic education is fully embraced.
The Contemporary Role of the Global Refugee Regime: Analysis of Equal Protection Under South Africa’s National Refugee Regime
Authors: Callixte Kavuro
Published: January 2025

This article analyses the role of the global refugee regime in protecting both de jure and de facto refugees in South Africa, with a specific focus on the principle of equality at the national level. It refers to South Africa’s commitment to achieving equality, and to the interpretation of equality in the post-1994 constitutional order. Building on this, the article discusses the impact of the guiding standards of favourable treatment outlined by the global refugee regime on the implementation of provisions within the national refugee regime. The main argument of the article is that treating refugees the same as non-citizens, in accordance with these guiding standards, undermines the constitutional protection of refugees’ socio-economic rights. Refugees are not in the same circumstances as vulnerable non-citizens with permanent residence permits or special dispensation permits, nor are they in the same circumstances as historically disadvantaged citizens. The position of refugees in South African society is unique. Therefore, a special and differentiated approach to their treatment regarding access to socio-economic rights is recommended. It is argued that this approach should be considered and implemented in the spirit of substantive equality to achieve a key objective of the global refugee regime.

Background: Despite the critical importance of sleep medicine within neurology, notable gaps in education and clinical practice persist among neurologists. This study aims to explore the extent of involvement and the challenges faced by Korean neurologists in sleep medicine, focusing on awareness of polysomnography training program, the operation of sleep study facilities, and educational exposure.Methods: An online survey collected responses from 233 neurologists, focusing on their demographics, knowledge of and involvement in sleep medicine, operation of sleep study facilities, and participation in residency training.Results: The findings indicated that 84.9% of neurologists were aware of polysomnography training program, primarily through professional societies. Nonetheless, 15.1% reported unfamiliarity with these initiatives, with 72.7% of this subgroup expressing interest in sleep medicine yet lacking access to information. In terms of clinical practice, 74 neurologists operated sleep study facilities, with 63% intending to expand. Key operational challenges included staff management, maintaining patient volumes, and inadequate institutional support. Among respondents from teaching hospitals, only 36 out of 114 reported active resident involvement in sleep study interpretations, predominantly hindered by excessive workloads and insufficient staffing.Conclusions: A significant number of neurologists have an interest in sleep medicine; however, substantial challenges impede effective education and clinical practice. These results underscore the need for improved educational resources and institutional support to enhance the growth and effectiveness of sleep medicine practices among neurologists.
