How a Wearable Camera can Benefit Soccer Players
Authors: Gardiman Gianluca
Published: May 2023

The advancements of technology in sports have played a crucial role in the progressive changes from an athlete performance standpoint. For example, there are many sports, like soccer that have seen many technological advances and devices introduced. In soccer, Video Assistance Review (VAR) is one of the more recent means of technology that is aimed at assisting officials, such as referees, to make the most correct decisions, according to the rules, on and during the field of play (Carlos, Ezequiel, Anton, 2019). This specific form of technology could possibly have changed the referee’s decision for Diego Maradona’s famous “Hand of God” goal for Argentina against England in the 1986 FIFA World Cup when he scored a clear goal with his hand and the referee failed to call a handball, against him (Britto et al., 2014). The result of that match resulted in an Argentina team win. Argentina went on to eventually win the FIFA World Cup that year. Thus, it is better late than never that this form of technology was implemented so that further incidents where referee human errors can be avoided. Goalline technology is another example of a revolutionary mean of technology that has positively integrated in the sport of soccer. England’s fate at the 2010 FIFA World Cup could have changed when England midfielder, Frank Lampard’s strike from outside the penalty box crossed over the goal line against Germany in the Round of 16 of the tournament. The referee failed to rule in favor of the goal for England, and were eventually eliminated that game, losing to Germany. Since goal-line technology had been introduced to the sport of soccer in 2012, referees across different professional soccer leagues have instant alerts on whether the ball has entered the net (Brockhoff, Huff, Maurer, Papenmeier, 2016). The following paper explores the idea of how technology, and wearable cameras can improve the performance of professional soccer players by providing them with the first person perspective of what they are faced with on the field.
Travelling While Arab: A Podcast and Study of the Effects of Social Media on Free Movement
Authors: Gargour Tamer
Published: May 2023

In August 2019, 17-year-old Harvard Freshman and Palestinian Refugee Ismail Ajjawwi was deported back to Lebanon upon arrival at Boston's Logan Airport by immigration officers for “political points of views that opposed the US” expressed by his friends on his Social Media. His free movement may have been deliberately sabotaged under the guise of contesting political agendas by association through the justification of requiring people to relinquish their personal social media in the interest of security. This paper and accompanying Podcast positively infers that Social Media can be arbitrarily used against Arabs to hinder or restrict free movement due to racial profiling, further discussing what constitutes credible political threat, the virtual degrees of separation between an individual and a ‘non-desirable’, and which countries are moving to protect the digital privacy rights of individuals and citizens. These issues will be addressed using a mix of virtual interviews worldwide with people who have experienced it, studying previous scholastic journals and articles, obtaining statements from immigration professionals and advisors, and creating a platform in the form of a Podcast for individuals to share their own stories and opinions.

Early Detection of Health Problems through Artificial Intelligence (Ai) Technology in Hospital Information Management: A Literature Review Study
Authors: Cahyo Lukito Mindi , Astuti Santi Dwi
Published: May 2023

Early detection of health problems needs to be supported by optimal hospital service quality subsystems through an integrated Hospital Management Information System. Artificial intelligence (AI) as a modern technology has entered the mainstream of clinical medicine. Diagnostics has traditionally been one of the main areas of AI in medicine. AI will broadly transform diagnostic and predictive analysis of medical images in the coming years. Studies in the fields of pathology and dermatology have demonstrated the ability of AI to outperform human diagnostics in accurately detecting and classifying various types of cancer. Artificial intelligence technology in the health aspect is useful in disease diagnosis and can analyze medical images to identify certain diseases so that they are able to distinguish between benign and malignant diseases. AI can also help identify the risk of mental illness and identify the risk of suicide among patients with psychiatric disorders or among certain populations, such as prisoners and soldiers. This helps doctors quickly get disease information and provide a more accurate disease diagnosis, thereby saving time for disease treatment.

Data mengatakan Indonesia merupakan negara yang kaya akan sumber daya alam, bahkan menjadi negara dengan sumber daya alam paling melimpah di dunia. Perspektif kekayaan intelektual, potensi-potensi itu merupakan produk yang dapat dilindungi berdasarkan kepemilikan komunal indikasi geografis. Setelah meratifikasi beberapa perjanjian internasional, terutama Persetujuan TRIPs, Indonesia berkewajiban memiliki regulasi yang memberikan perlindungan kepada indikasi geografis. Pada beberapa regulasi yang pernah ada, pemerintah daerah diberikan kewenangan sebagai pemohon saat pendaftaran sebuah produk sebagai indikasi geografis di kementerian. Faktanya, peran pemerintah daerah kurang optimal, terutama bila dilihat dari potensi yang dimiliki, ditambah regulasi sifatnya tidak imperatif. Penelitian ini bersifat normative dengan pendekatan perundang-undangan. Dari hasil kajian yang sudah dilakukan, didapati hasil bahwa kedudukan pemerintah daerah dalam Undang-Undang Nomor 20 Tahun 2016 tentang Merek dan Indikasi Geografis tidak imperatif mengatur secara spesifik kedudukan pemerintah daerah, sehingga dengan yang melimpah hanya sedikit yang didaftarkan akibat kurangnya kontribusi pemerintah daerah.

This research discusses the legal force of binding sale and purchase agreements under the hands made by the parties without witnesses and only waarmarking by a notary. The research method used is the analytical descriptive method, a research method that reveals problems, analyzes a problem, examines, and interprets it into conclusions and suggestions in a systematic way so that it is easy to understand. Normative Juridical approach method, namely legal research that uses secondary data sources such as principles the doctrines in the science of law. The results of the study can be concluded that the underhand Sale and Purchase Agreement (PPJB) is a form of agreement between two parties who agree to bind themselves, which is made jointly. Even though PPJB under the hand can be made freely by the parties who want to make an agreement, it may not violate the provisions of Article 1320 of the KUHPerdata. PPJB made before an authorized official and PPJB made privately have the same legal force. PPJB under the hand made by the parties without witnesses and only waarmarking by a notary, the strength of proof is only between the parties. If the parties do not deny and acknowledge the signature in the agreement, then the PPJB under the hand has perfect power as an authentic deed.

Hipotensão pós-exercício intervalado de alta intensidade com resistência elástica: um estudo piloto
Authors: Alves Redley da Silva , Neves Leticia Nascimento Santos , Gasparini Neto Victor Hugo , Carletti Luciana
Published: May 2023

Introdução: Está estabelecido que o treinamento aeróbio contínuo reduz a PA no pós-esforço, conhecido como hipotensão pós-exercício. Ergômetros tradicionais como esteiras e cicloergômetros são comumente utilizados como meio de treinamento. Eles são caros e isso limita o acesso à população em geral. Uma alternativa é o uso da corrida com resistência elástica. Entretanto não se sabe se a aplicação de uma sessão de treinamento intervalado de alta intensidade, com resistência elástica, apresenta respostas hemodinâmicas agudas favoráveis pós-exercício. Objetivo: Descrever e comparar as respostas hemodinâmicas na recuperação de uma sessão de treinamento intervalado realizada na esteira e a com resistência elástica realizadas na mesma intensidade. Métodos: Quatro adultos (24,25 ± 2,75 anos) saudáveis executaram uma sessão de treinamento intervalado de alta intensidade na esteira ergométrica e outra sessão com resistência elástica a 85% do VO2máx, com intervalo entre eles de uma semana e uma situação controle. Antes e após as sessões, foram monitoradas as variáveis hemodinâmicas por 60 minutos: pressão arterial sistólica, pressão arterial diastólica, frequência cardíaca, volume sistólico, débito cardíaco e resistência vascular periférica monitorados por fotopletismografia por infravermelho (Finometer). Resultados: O treinamento intervalado com resistência elástica apresentou resposta hemodinâmica aguda significativa com a queda da pressão arterial sistólica e da resistência vascular periférica em relação ao dia controle. Comparando os protocolos, apenas a resistência elástica causou hipotensão pós-exercício (p < 0,05), por até 40 minutos. Conclusão: O protocolo com resistência elástica promoveu hipotensão pós-exercício com queda da pressão arterial sistólica acompanhada de redução da resistência vascular periférica.

Published: May 2023

La diabetes mellitus gestacional constituye la complicación metabólica más frecuente en el embarazo. A nivel mundial, tiene una prevalencia que varía entre el 1 – 14%, siendo América Latina la más susceptible.
Esta patología es de alto impacto, entre los factores de riesgo más relacionados para la aparición de diabetes gestacional fueron la edad avanzada, obesidad y los antecedentes patológicos, que aumenta 1,2 veces la probabilidad de desarrollar diabetes gestacional. Por otro lado, tener en cuenta que no todas las mujeres que desarrollan diabetes gestacional tienen estos factores de riesgo. De hecho, muchas mujeres con diabetes gestacional no tienen ningún factor de riesgo.
Estas pacientes presentan un riesgo de 35 a 60 % de desarrollar diabetes mellitus 10 a 20 años después del embarazo. Por ello, es importante reconocer y tratar cualquier grado de alteración de la glucemia que afecte la gestación y que conduce a la disminución de complicaciones maternas y fetales, inmediatas y a largo plazo. Se concluye que la diabetes gestacional es un problema complejo que afecta al binomio madre e hijo, además que presenta muy altas tasas de recurrencia, por lo que requiere de soluciones sistémicas e integrales, ya que corresponde a un problema de salud pública.
Calidad en Doppler materno fetal: Propuesta de una Escala Objetiva Modificada de calidad y auditoría
Authors: Castillo-Urquiaga Walter
Published: May 2023

La debilidad técnica y en la comprensión hemodinámica genera evaluaciones Doppler de baja calidad con persistencia de desenlaces adversos, altos costos, vigilancia o tratamiento innecesarios y limitado avance del conocimiento fisiopatológico.

La investigación y práctica clínica relacionadas al Doppler materno fetal muestran impacto poco significativo, discrepancias e incluso incongruencias; si bien un porcentaje de esto se genera por la no uniformidad en la terminología diagnóstica, las tablas de referencia y el manejo, otro porcentaje se explica por la baja calidad en la evaluación Doppler.

Las recomendaciones ya establecidas para la calidad Doppler pueden representarse en una herramienta que permita mejorarla y evaluarla objetivamente. Esto podría no solo disminuir los desenlaces adversos sino que tornaría a las investigaciones más uniformes y con evidencias más sólidas.

La calidad en las medidas de los índices Doppler dependen de las técnicas de evaluación y medición, obtención de un espectro óptimo y de su registro en condiciones basales y libre de factores de confusión o intervinientes; la falla en uno o más de ésto genera mediciones falsamente anormales o falsamente normales llevando a manejos innecesarios o pérdida en la oportunidad de evitar desenlaces adversos.

Proponemos una escala modificada con parámetros objetivos de calidad-auditoría para su incorporación a la práctica clínica rutinaria. Esta evalúa 10 criterios: 1) Sitio anatómico, 2) Magnificación, 3) Claridad de imagen, 4) Ángulo de insonación, 5) Velocidad de barrido, 6) PRF y Línea de Base, 7) Volúmen de muestra, 8) Factor de confusión, 9) Filtro adecuado y 10) Confiabilidad.

Tensile testing at the Extremely Low Temperature of 6K : Microstructure and Mechanical Properties of a Fe-Mn-Cr Steel
Authors: Kim Young-Kyun , Lim Ka-Ram , Na Young-Sang
Published: May 2023

Materials with superior cryogenic strength and good ductility are increasingly in demand for resident friendly liquid-hydrogen (20K) storage tanks. Additionally, the space industry also requires materials that retain excellent mechanical properties at extremely low temperatures. However, mechanical testing at such low temperatures is highly limited due to the difficulties in achieving and maintaining such conditions, while also providing adequate thermal insulation to prevent heat transfer from the surrounding environment. In this study, we present a novel tensile testing technique for a Fe-15Mn-13Cr-3Si-3Ni-0.1C (wt.%) steel at the temperature of liquid helium. To minimize the use of expensive liquid helium, we adopted a method of injecting liquid helium vapor and set the temperature for tensile testing at 6 K. The present alloy has a single face-centered cubic (FCC) structure with a large amount of stacking faults after annealing treatment. The Fe-Mn-Cr steel exhibited a superior ultimate tensile strength of 1200 MPa and good ductility of 35% at 6K. Moreover, compared with room temperature tensile tests, discontinuous plastic flow, i.e. serrated flow, occurred at extremely low temperature.

Formação e profissionalização de professores: a identidade profissional em questão
Authors: Oliveira Reginaldo de Lima , Vieira Josimar de Aparecido , Stelmach Cibele Savi
Published: May 2023

A trí­ade conceitual de profissionalidade, profissionalismo e profissionalização são aspectos imprescindí­veis a serem pontuados na consolidação da identidade docente. Neste ensaio esses princí­pios são analisados de forma articulada com a realidade atual, contando com apoio de revisão bibliográfica de escritos dos anos noventa até o momento atual. Constituí­do numa abordagem qualitativa, buscou-se compreender a identidade profissional dos professores tendo como parâmetros aspectos da realidade educacional contemporânea. Por se tratar de tema extenso, a produção encontra-se organizada de modo que apresenta conceitos da trí­ade profissionalidade, profissionalismo e profissionalização, aspectos da realidade atual da profissão docente e alternativas de ação para a constituição da identidade profissional dos professores. Esses pontos, apresentados de formainterligada e interdependente, indicam que as dificuldades que são impostas por polí­ticas públicas, formuladas não raro com intuitos de controle e retirada da autonomia do professor, produzem impactos diretos em sua profissionalização. Noutra direção, propostas de reversão de imagem da identidade docente poderão ser construí­das a partir da interação dos problemas da educação junto à comunidade escolar, reforçando aspectos de profissionalismo, articulando ações com respaldo externo, possibilitando assim levar a realidade da escola e da educação para além dos seus muros da escola.
A concepção de força de Roger Boscovich
Authors: Martins Milene Rodrigues , Neves Marcos Cesar Danhoni , Gardelli Daniel
Published: May 2023

O presente artigo apresenta, ainda que suscintamente, a vida e obra do importante fí­sico, astrônomo e filósofo Roger Joseph Boscovich (1711-1787). Em especial, busca-se apresentar as relevantes e por vezes desconhecidas contribuições de Boscovich para o desenvolvimento do conceito de força no contexto histórico do século XVIII, tendo em vista sua concepção de que as partí­culas elementares, das quais a matéria é constituí­da, eram pontos não estendidos e indivisí­veis e, de acordo com a distância em que se encontravam estes pontos, era possí­vel presenciar uma força atrativa ou repulsiva, que pode ser representada graficamente por uma curva. A teoria de Boscovich permitiu uma compreensão do conceito de força.

Published: May 2023

As a bone tissue engineering scaffold, the objective of this study was to design hierarchical bioceramics based on an electrospun composite of carbon nanofibers (CNF) reinforced with hydroxyapatite (HA) and bioactive glasses (BGs) nanoparticles. The performance of the nanofiber as a scaffold for bone tissue engineering was enhanced by reinforcing it with hydroxyapatite and bioactive glass nanoparticles through a hydrothermal process. The influence of HA and BGs on the morphology and biological properties of carbon nanofibers was examined. The prepared materials were evaluated for cytotoxicity in vitro using the water-soluble tetrazolium salt assay (WST-assay) on Osteoblast-like (MG-63) cells, and oste-ocalcin (OCN), alkaline phosphatase (ALP) activity, total calcium, total protein, and tar-trate-resistant acid phosphatase (TRAcP) were measured. The WST-1, OCN, TRAcP, total calcium, total protein, and ALP activity tests demonstrated that scaffolds reinforced with HA and BGs had excellent in vitro biocompatibility (cell viability and proliferation) and were suitable for repairing damaged bone by stimulating bioactivity and biomarkers of bone cell formation.
Analytical and numerical case studies on tailoring stiffness for the design of structures with displacement control

Published: May 2023

This paper discusses the role that structural stiffness plays in the context of designing adaptive structures. The focus is on load-bearing structures with adaptive displacement control. A design methodology is implemented to minimize the control effort by making the structure as stiff as possible against external loads and as flexible as possible against the effect of actuation. This rationale is tested using simple analytical and numerical case studies.
Membrane trafficking in breast cancer progression: protein kinase D comes into play
Authors: Gutiérrez-Galindo Elena , Yilmaz Zeynep Hazal , Hausser Angelika
Published: May 2023

Protein kinase D (PKD) is a serine/threonine kinase family that controls important cellular functions, most notably playing a key role in the secretory pathway at the trans-Golgi network. Aberrant expression of PKD isoforms has been found mainly in breast cancer, where it promotes various cellular processes such as growth, invasion, survival and stem cell maintenance. In this review, we discuss the isoform-specific functions of PKD in breast cancer progression, with a particular focus on how the PKD controlled cellular processes might be linked to deregulated membrane trafficking and secretion. We further highlight the challenges of a therapeutic approach targeting PKD to prevent breast cancer progression.
Hippocampal versus cortical deletion of cholinergic receptor muscarinic 1 in mice differentially affects post-translational modifications and supramolecular assembly of respiratory chain-associated proteins, mitochondrial ultrastructure, and respiration: implications in Alzheimer’s disease

Published: May 2023

Introduction: In a previous retrospective study using postmortem human brain tissues, we demonstrated that loss of Cholinergic Receptor Muscarinic 1 (CHRM1) in the temporal cortex of a subset of Alzheimer’s patients was associated with poor survival, whereas similar loss in the hippocampus showed no such association. Mitochondrial dysfunction underlies Alzheimer’s pathogenesis. Therefore, to investigate the mechanistic basis of our findings, we evaluated cortical mitochondrial phenotypes in Chrm1 knockout (Chrm1−/−) mice. Cortical Chrm1 loss resulted in reduced respiration, reduced supramolecular assembly of respiratory protein complexes, and caused mitochondrial ultrastructural abnormalities. These mouse-based findings mechanistically linked cortical CHRM1 loss with poor survival of Alzheimer’s patients. However, evaluation of the effect of Chrm1 loss on mouse hippocampal mitochondrial characteristics is necessary to fully understand our retrospective human tissue-based observations. This is the objective of this study.

Methods: Enriched hippocampal and cortical mitochondrial fractions (EHMFs/ECMFs, respectively) derived from wild-type and Chrm1−/− mice were used to measure respiration by quantifying real-time oxygen consumption, supramolecular assembly of oxidative phosphorylation (OXPHOS)-associated proteins by blue native polyacrylamide gel electrophoresis, post-translational modifications (PTMs) by isoelectric focusing (IEF), and mitochondrial ultrastructure by electron microscopy.

Results: In contrast to our previous observations in Chrm1−/− ECMFs, EHMFs of Chrm1−/− mice significantly increased respiration with a concomitant increase in the supramolecular assembly of OXPHOS-associated proteins, specifically Atp5a and Uqcrc2, with no mitochondrial ultrastructural alterations. IEF of ECMFs and EHMFs from Chrm1−/− mice showed a decrease and an increase, respectively in a negatively charged (pH∼3) fraction of Atp5a relative to the wild-type mice, with a corresponding decrease or increase in the supramolecular assembly of Atp5a and respiration indicating a tissue-specific signaling effect.

Discussion: Our findings indicate that loss of Chrm1 in the cortex causes structural, and physiological alterations to mitochondria that compromise neuronal function, whereas Chrm1 loss in the hippocampus may benefit neuronal function by enhancing mitochondrial function. This brain region-specific differential effect of Chrm1 deletion on mitochondrial function supports our human brain region-based findings and Chrm1−/− mouse behavioral phenotypes. Furthermore, our study indicates that Chrm1-mediated brain region-specific differential PTMs of Atp5a may alter complex-V supramolecular assembly which in turn regulates mitochondrial structure-function.
Inflammation versus regulation: how interferon-gamma contributes to type 1 diabetes pathogenesis

Published: May 2023

Type 1 diabetes is an autoimmune disease with onset from early childhood. The insulin-producing pancreatic beta cells are destroyed by CD8+ cytotoxic T cells. The disease is challenging to study mechanistically in humans because it is not possible to biopsy the pancreatic islets and the disease is most active prior to the time of clinical diagnosis. The NOD mouse model, with many similarities to, but also some significant differences from human diabetes, provides an opportunity, in a single in-bred genotype, to explore pathogenic mechanisms in molecular detail. The pleiotropic cytokine IFN-γ is believed to contribute to pathogenesis of type 1 diabetes. Evidence of IFN-γ signaling in the islets, including activation of the JAK-STAT pathway and upregulation of MHC class I, are hallmarks of the disease. IFN-γ has a proinflammatory role that is important for homing of autoreactive T cells into islets and direct recognition of beta cells by CD8+ T cells. We recently showed that IFN-γ also controls proliferation of autoreactive T cells. Therefore, inhibition of IFN-γ does not prevent type 1 diabetes and is unlikely to be a good therapeutic target. In this manuscript we review the contrasting roles of IFN-γ in driving inflammation and regulating the number of antigen specific CD8+ T cells in type 1 diabetes. We also discuss the potential to use JAK inhibitors as therapy for type 1 diabetes, to inhibit both cytokine-mediated inflammation and proliferation of T cells.
Tight hydrophobic core and flexible helices yield MscL with a high tension gating threshold and a membrane area mechanical strain buffer

Published: May 2023

The mechanosensitive (MS) channel of large conductance, MscL, is the high-tension threshold osmolyte release valve that limits turgor pressure in bacterial cells in the event of drastic hypoosmotic shock. Despite MscL from Mycobacterium tuberculosis (TbMscL) being the first structurally characterized MS channel, its protective mechanism of activation at nearly-lytic tensions has not been fully understood. Here, we describe atomistic simulations of expansion and opening of wild-type (WT) TbMscL in comparison with five of its gain-of-function (GOF) mutants. We show that under far-field membrane tension applied to the edge of the periodic simulation cell, WT TbMscL expands into a funnel-like structure with trans-membrane helices bent by nearly 70°, but does not break its ‘hydrophobic seal’ within extended 20 μs simulations. GOF mutants carrying hydrophilic substitutions in the hydrophobic gate of increasing severity (A20N, V21A, V21N, V21T and V21D) also quickly transition into funnel-shaped conformations but subsequently fully open within 1–8 μs. This shows that solvation of the de-wetted (vapor-locked) constriction is the rate-limiting step in the gating of TbMscL preceded by area-buffering silent expansion. Pre-solvated gates in these GOF mutants reduce this transition barrier according to hydrophilicity and the most severe V21D eliminates it. We predict that the asymmetric shape-change of the periplasmic side of the channel during the silent expansion provides strain-buffering to the outer leaflet thus re-distributing the tension to the inner leaflet, where the gate resides.

Background

Human T-cell leukemia virus type 1 (HTLV-1) is a retrovirus known to cause two major diseases: adult T-cell leukemia/lymphoma and a progressive neuromyelopathy—tropical spastic paraparesis. Many viruses may be involved in the pathogenesis of thyroiditis; however, few studies have focused on the role of HTLV-1. We aimed to investigate the association between HTLV-1 and biological thyroid dysfunction.

Methods

We included 357 patients with a positive HTLV-1 serology and thyroid-stimulating hormone assay data between 2012 and 2021 in a hospital in French Guiana; we compared the prevalence of hypothyroidism and hyperthyroidism in this group with that in an HTLV-1-negative control group (722 persons) matched for sex and age.

Results

The prevalence of hypothyroidism and hyperthyroidism in patients with HTLV-1 infection was significantly higher than that in the control group (11% versus 3.2% and 11.3% versus 2.3%, respectively; p < 0.001).

Conclusion

Our study shows, for the first time, the association between HTLV-1 and dysthyroidism in a large sample, suggesting that thyroid function exploration should be systematically implemented in this population as this may have an impact on therapeutic management.
Gender-based vulnerabilities for women during natural disasters in Bangladesh
Authors: Fatema Syadani Riyad , East Leah , Islam Shahidul , Usher Kim
Published: May 2023

Introduction

Factors that negatively impact women's disaster experiences include poor disaster preparedness, lack of access to a safe place, displacement worries, distance from shelters, risk of abuse in shelters, poverty, and low cultural position of women in rural Bangladesh. This study aimed to give voice to women who experienced gender-based vulnerabilities during natural disasters.

Methods

The research was conducted with women in the two disaster-prone areas utilizing a qualitative approach. Women, aged 18 years or above, who were permanent residents of the selected disaster-prone areas and have experienced one or more disasters, were invited to participate in the study. Twenty-four women volunteered to participate. Data were collected through semi-structured in-depth interview recordings containing questions on sociodemographic characteristics and open-ended questions to assess gender-based vulnerabilities during disasters; data were analyzed using thematic analysis techniques.

Results

One main theme and six sub-themes emerged from the analysis. Women were often in the middle of making life choices between the risk of being abused and death in disasters. Shelters lacked privacy, heightened the risk of abuse, and women faced social stigma if displaced from their homes during a disaster. The women also experienced health risks because of inadequate hygiene and poor living arrangements such as a lack of adequate shelters, toilet facilities, and secure gender-segregated living arrangements if relocation was essential during a disaster.

Discussion

Findings from this study provide guidance to policymakers and disaster aid organizations on disaster preparedness and post-disaster facilities to address the socio-cultural needs of rural women in disaster-prone areas of Bangladesh.
