Published: March 2024

Abstract. The actuator line method (ALM) is increasingly being preferred to the ubiquitous blade element momentum (BEM) approach in several applications related to wind turbine simulation, thanks to the higher level of fidelity required by the design and analysis of modern machines. Its capability to resolve blade tip vortices and their effect on the blade load profile is, however, still unsatisfactory, especially when compared to other medium-fidelity methodologies such as the lifting line theory (LLT). Despite the numerical strategies proposed so far to overcome this limitation, the reason for such behavior is still unclear. To investigate this aspect, the present study uses the ALM tool developed by the authors for the ANSYS® Fluent® solver (v. 20.2) to simulate a NACA0018 finite wing for different pitch angles. Three different test cases were considered: high-fidelity blade-resolved computational fluid dynamics (CFD) simulations (to be used as a benchmark), standard ALM, and ALM with the spanwise force distribution coming from blade-resolved data (frozen ALM). The last option was included to isolate the effect of force projection, using three different smearing functions. For the postprocessing of the results, two different techniques were applied: the LineAverage sampling of the local angle of attack along the blade and state-of-the-art vortex identification methods (VIMs) to outline the blade vortex system. The analysis showed that the ALM can account for tip effects without the need for additional corrections, provided that the correct angle of attack sampling and force projection strategies are adopted.

Impact of Farm Size and Sociodemographic Characteristics on Agricultural Households’ Food Security
Authors: Kadir K , Prasetyo Octavia Rizky 
Published: March 2024

Most agricultural households in Indonesia are small-scale farmers making them prone to food insecurity. Until recently, no study has assessed the impact of farm size and sociodemographic characteristics on the food insecurity status of agricultural households using a nationwide agricultural household survey in Indonesia. Our study aims to address this gap by utilizing the results of the first Indonesian Agricultural Integrated Survey conducted by BPS in 2021. Applying the Rasch Model and Multinomial Logistic Regression, we found that the farm size has a positive impact in lowering the probability of agricultural households experiencing moderate or severe levels of food insecurity. Our study also found that agricultural households with a higher probability of being food insecure are characterized by having higher members of households, relying only on agriculturalactivities for their livelihood, lower education attainment of household heads, and being led by female farmers. Our study recommends improving the farmers’ agricultural scale by focusing on the improvement of the yield. It can be done through the adoption of mechanization and digital technology. Moreover, we also recommend a social assistance programme for food security targeting agricultural households with characteristics identifiedin our findings.
Does R&D Stimulate Firm’s Efficiency in the Indonesian Manufacturing Sector?
Authors: Yasin Mohammad Zeqi 
Published: March 2024

The impact of research and development (R&D) spending has been shown significantly in promoting country’s economic growth and productivity. Hence, we examine the research question by employing Indonesian manufacturing firm-level dataset in the years of 2017–2019 and by using Stochastic Frontier Analysis (SFA) to reveal whether heterogeneous firm’s R&D spending contributes to the efficiency performance of the company. The finding reveals the robust positive effect of R&D spending to the efficiency performance, which implies that firms allocating more R&D spending will perform better efficiency due to, for example, managerial expertise improvements. An interesting finding is shown by the interaction model for which larger R&D allocated by foreign firm will boost better efficiency than that allocated by domestic firms, supporting prior arguments that foreign firm can be the driver of innovation as they are more likely to be closer to the world technology frontier. Several policy implications are suggested such as in-house R&D program to encourage human capital development and tax incentive to avoid market rivalry with foreign firms.

Published: March 2024

O presente artigo científico possui o intuito de trazer à luz das discussões acadêmicas o subsistema jurídico Direito Antidiscriminatório, tema recente e que ao longo dos últimos anos tem sido difundido no Brasil e em outros países e justifica-se pelos notórios problemas que o racismo causa na população negra brasileira. Seu objetivo geral é apresentar o Direito Antidiscriminatório como instrumento de promoção da equidade racial. Os objetivos específicos foram explanados sequencialmente, iniciando pela apresentação, partindo da sua eclosão até a sua chegada ao Brasil por meio de instrumentos legais internacionais adotados no país, após buscou-se diferenciar termos que em geral são confundidos entre si ou colocados numa mesma prateleira, são eles, a discriminação racial, o preconceito racial e o racismo, além de elucidar o significado de equidade racial. Tais explicações mostram-se necessárias uma vez que para iniciar-se um debate sobre relações raciais é preciso primeiramente possuir o máximo de letramento racial possível. Por fim, é feito um estudo comparado entre a Declaração de Quebec e as legislações latinas, a fim de explorar e entender em que momento os países vizinhos ao Brasil se encontram no debate racial e no enfrentamento ao racismo e seus efeitos. O problema e sua respectiva hipótese de resolução apresentada demonstraram que o Direito Antidiscriminatório, se bem utilizado, pode ser um instrumento de transformação social no tocante ao enfrentamento ao racismo em diversos cenários apresentados. Para a realização deste artigo utilizou-se a pesquisa bibliográfica, com método histórico no que se refere ao procedimento.

A pandemia da covid-19 chegou ao Brasil no dia 26 de fevereiro de 2020, no Estado de São Paulo (SP), através de um viajante retornando da Itália. Com o avanço dos casos confirmados da doença, mostrou-se necessário uma mobilização que desencadeou em uma série de mudanças nos modelos de atenção à saúde. Na Atenção Primária em Saúde (APS), as atividades antes consolidadas passaram por reestruturações que modificaram as características dos serviços e ações desenvolvidas pelos profissionais da Estratégia Saúde da Família (ESF). A presente pesquisa tem por objetivo descrever as dificuldades e estratégias encontradas por Agentes Comunitários de Saúde (ACSs) da ESF na visita domiciliar durante o processo de readequação das Unidades Básicas de Saúde (UBS) de referência para a COVID-19 e UBS de apoio no período 2020-2021. Metodologia: realizou-se um estudo qualitativo com abordagem descritivo exploratória, cujos dados da pesquisa foram obtidos por meio de formulário aplicados aos profissionais ACSs atuantes nas UBS do Município de Boa Vista - RR. Esses dados foram analisados por meio da análise de conteúdo (bardin,1977), cuja a técnica utilizada foi de análise categorial ou temática, que consiste em leitura, transcrição e mapeamento das respostas, que resultaram nas seguintes linhas temáticas: (1) caracterização social demográfica dos ACSs, (2) capacitação profissional, (3) reestruturação e dinamização da Atenção Básica na pandemia, e (4) cenário da visita domiciliar na pandemia. Resultados: A pandemia afetou as visitas domiciliares realizadas pelos ACSs, devido à baixa adesão dos profissionais em capacitações e pela necessidade em atender as demandas internas das UBS, com prioridade aos atendimentos com covid-19 em relação a outras atividades. Conclui-se que a pandemia revelou a fragilidade do sistema de saúde tanto na capacidade de suprir a demanda por meios de equipamentos, materiais e insumos, quanto pela capacidade de gerenciar as dificuldade e demanda em situação de limite ou de emergência em proporção extraordinária, ora pelo excesso de demanda, ou complexidade logística, ou devido gravidade do quadro sanitário.

Published: March 2024

Introduction: While current research highlights student anxiety globally, limited data exists on the specific situation of Vietnamese medical students. This study addresses this gap by investigating the prevalence and contributing factors of anxiety within this population, aiming to gain a deeper understanding of their mental health experiences.
Methods: Utilizing a convenience sampling technique, 400 medical students from Ho Chi Minh City University of Medicine & Pharmacy were surveyed using the Zung Self-Rating Anxiety Scale and a custom questionnaire assessing factors contributing to anxiety. Data analysis included descriptive statistics, independent-samples t-tests, ANOVA, and Pearson's correlation.
Results: Findings revealed mild to moderate anxiety levels among medical students (M = 49.68 ± 11.54), with significant differences based on gender, academic year, and academic performance. Males (M = 51.27 ± 12.26) and senior students (M = 53.18 ± 12.50) reported higher anxiety levels. Key contributors to anxiety included financial concerns, major examinations, and discrepancies between perceived and desired academic performance. Notably, a strong positive correlation was found between academic performance discrepancies and anxiety levels (r = 0.888, p < 0.001).
Conclusion: The study highlights a potentially higher prevalence of anxiety among medical students than previously reported, emphasizing the need for targeted interventions. Understanding the multifaceted nature of anxiety and its contributing factors is crucial for fostering a supportive learning environment, ultimately nurturing well-equipped and resilient healthcare professionals.
Australian consensus statement on doxycycline post‐exposure prophylaxis (doxy‐PEP) for the prevention of syphilis, chlamydia and gonorrhoea among gay, bisexual and other men who have sex with men
Authors: Cornelisse Vincent J , Riley Benjamin , Medland Nicholas A

AbstractIntroductionDoxycycline post‐exposure prophylaxis (doxy‐PEP) involves consuming 200 mg of doxycycline up to 72 hours after a condomless sex act to reduce the risk of bacterial sexually transmitted infections (STIs). Recent clinical trials of doxy‐PEP have demonstrated significant reductions in syphilis, chlamydia and, to a lesser degree, gonorrhoea among gay, bisexual and other men who have sex with men (GBMSM). There is a high level of interest in doxy‐PEP in the GBMSM community and, in response, the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine (ASHM) held a national consensus conference with the aim of creating preliminary guidance for clinicians, community, researchers and policy makers.Main recommendationsThere was broad agreement that doxy‐PEP should be considered primarily for the prevention of syphilis in GBMSM who are at risk of this STI, with a secondary benefit of reductions in other bacterial STIs. At the end of the consensus process, there remained some disagreement, as some stakeholders felt strongly that doxy‐PEP should be considered only for the prevention of syphilis in GBMSM, and that the risk of increasing antimicrobial resistance outweighed any potential benefit from reductions in other bacterial STIs in the target population. The national roundtable made several other recommendations for clinicians, community, researchers and policy makers, as detailed in this article. ASHM will support the development of detailed clinical guidelines and education materials on doxy‐PEP (www.ashm.org.au/doxy‐pep).Changes in management as a result of this consensus statementFor GBMSM at high risk of syphilis, and perhaps other bacterial STIs, clinicians may consider prescribing doxy‐PEP for a limited period of time, followed by a review of ongoing need. Unlike human immunodeficiency virus (HIV) pre‐exposure prophylaxis (PrEP), doxy‐PEP may not be suitable as a population‐level intervention and should instead be used more selectively.
