Cross-attention learning enables real-time nonuniform rotational distortion correction in OCT
Authors: Zhang Haoran , Yang Jianlong , Zhang Jingqian , Zhao Shiqing , Zhang Aili
Published: December 2023

Nonuniform rotational distortion (NURD) correction is vital for endoscopic optical coherence tomography (OCT) imaging and its functional extensions, such as angiography and elastography. Current NURD correction methods require time-consuming feature tracking/registration or cross-correlation calculations and thus sacrifice temporal resolution. Here we propose a cross-attention learning method for the NURD correction in OCT. Our method is inspired by the recent success of the self-attention mechanism in natural language processing and computer vision. By leveraging its ability to model long-range dependencies, we can directly obtain the spatial correlation between OCT A-lines at any distance, thus accelerating the NURD correction. We develop an end-to-end stacked cross-attention network and design three types of optimization constraints. We compare our method with two traditional feature-based methods and a CNN-based method on two publicly-available endoscopic OCT datasets. We further verify the NURD correction performance of our method on 3D stent reconstruction using a home-built endoscopic OCT system. Our method achieves a ∼3 × speedup to real time (26 ± 3 fps), and superior correction performance.

Siphophages have a long, flexible, and noncontractile tail that connects to the capsid through a neck. The phage tail is essential for host cell recognition and virus–host cell interactions; moreover, it serves as a channel for genome delivery during infection. However, the in situ high-resolution structure of the neck–tail complex of siphophages remains unknown. Here, we present the structure of the siphophage lambda “wild type,” the most widely used, laboratory-adapted fiberless mutant. The neck–tail complex comprises a channel formed by stacked 12-fold and hexameric rings and a 3-fold symmetrical tip. The interactions among DNA and a total of 246 tail protein molecules forming the tail and neck have been characterized. Structural comparisons of the tail tips, the most diversified region across the lambda and other long-tailed phages or tail-like machines, suggest that their tail tip contains conserved domains, which facilitate tail assembly, receptor binding, cell adsorption, and DNA retaining/releasing. These domains are distributed in different tail tip proteins in different phages or tail-like machines. The side tail fibers are not required for the phage particle to orient itself vertically to the surface of the host cell during attachment.
Kin-recognition and predation shape collective behaviors in the cannibalistic nematode Pristionchus pacificus
Authors: Hiramatsu Fumie , Lightfoot James W.
Published: December 2023

Kin-recognition is observed across diverse species forming an important behavioral adaptation influencing organismal interactions. In many species, the molecular mechanisms involved are difficult to characterize, but in the nematode Pristionchus pacificus molecular components regulating its kin-recognition system have been identified. These determine its predatory behaviors towards other con-specifics which prevents the killing and cannibalization of kin. Importantly, their impact on other interactions including collective behaviors is unknown. Here, we explored a high altitude adapted clade of this species which aggregates abundantly under laboratory conditions, to investigate the influence of the kin-recognition system on their group behaviours. By utilizing pairwise aggregation assays between distinct strains of P. pacificus with differing degrees of genetic relatedness, we observe aggregation between kin but not distantly related strains. In assays between distantly related strains, the aggregation ratio is frequently reduced. Furthermore, abolishing predation behaviors through CRISPR/Cas9 induced mutations in Ppa-nhr-40 result in rival strains successfully aggregating together. Finally, as Caenorhabditis elegans are found naturally occurring with P. pacificus, we also explored aggregation events between these species. Here, aggregates were dominated by P. pacificus with the presence of only a small number of predators proving sufficient to disrupt C. elegans aggregation dynamics. Thus, aggregating strains of P. pacificus preferentially group with kin, revealing competition and nepotism as previously unknown components influencing collective behaviors in nematodes.

Published: December 2023

This study aims to investigate socioeconomic disparities in nutritional status among ever-married women in Bangladesh and to break down urban-rural differences in the underlying causes of undernutrition. We utilized data from the Bangladesh Demographic and Health Survey 2017–18, a sample size of 18328 ever-married women, including 5170 from urban residences, and 13159 from rural residences. To explore socioeconomic inequality, we employed a concentration indexing measure, while a multiple binary logistic regression model was carried out to identify the determinants associated with the outcome variable. A Blinder-Oaxaca decomposition analysis was performed to decompose the urban-rural gap in women’s nutritional status using associated factors. The prevalence of undernutrition among ever-married women in Bangladesh was 12 percent. Notably, this percentage varied by region, with urban residents accounting for 8.6% and rural residents accounting for 13.3%. Our findings confirmed that undernutrition was more prevalent among women with lower wealth indexes in Bangladesh, as indicated by the concentration index (CIX = −0.26). The multivariable analysis investigating the determinants of undernutrition status among ever-married women, with a focus on residence revealed significant associations with respondent age, education, marital status, mass media access, wealth status, and division. According to the Blinder-Oaxaca decomposition and its extension, the prevalence was significantly higher in rural residences of Bangladesh than in urban residences, and the endowment effect explained 86 percent of the total urban-rural difference in undernutrition prevalence. The results of this study indicate that the factors that influence women’s nutritional status in rural areas play a significant role in the gap, and the majority of the gap is caused by education and economic position. In order to effectively promote maternal health policies in Bangladesh, intervention techniques should be created that are aimed at the population, that is, the poorest and least educated.

Published: December 2023

Background

Patient and public involvement (PPI) in trials aims to enhance research by improving its relevance and transparency. Planning for statistical analysis begins at the design stage of a trial within the protocol and is refined and detailed in a Statistical Analysis Plan (SAP). While PPI is common in design and protocol development it is less common within SAPs. This study aimed to reach consensus on the most important and relevant statistical analysis items within an SAP to involve patients and the public.

Methods

We developed a UK-based, two-round Delphi survey through an iterative consultation with public partners, statisticians, and trialists. The consultation process started with 55 items from international guidance for statistical analysis plans. We aimed to recruit at least 20 participants per key stakeholder group for inclusion in the final analysis of the Delphi survey. Participants were asked to vote on each item using a Likert scale from 1 to 9, where a rating of 1 to 3 was labelled as having ‘limited importance’; 4 to 6 as ‘important but not critical’ and 7 to 9 as ‘critical’ to involve patients and the public. Results from the second round determined consensus on critical items for PPI.

Results

The consultation exercise led to the inclusion of 15 statistical items in the Delphi survey. We recruited 179 participants, of whom 72% (129: 36 statisticians, 29 patients or public partners, 25 clinical researchers or methodologists, 27 trial managers, and 12 PPI coordinators) completed both rounds. Participants were on average 48 years old, 60% were female, 84% were White, 64% were based in England and 84% had at least five years’ experience in trials. Four items reached consensus regarding critical importance for patient and public involvement: presentation of results to trial participants; summary and presentation of harms; interpretation and presentation of findings in an academic setting; factors impacting how well a treatment works. No consensus was reached for the remaining 11 items. In general, the results were consistent across stakeholder groups.

Discussion

We identified four critical items to involve patients and the public in statistical analysis plans. The remaining 11 items did not reach consensus and need to be considered in a case-by-case basis with most responders considering patient and public involvement important (but not critical). Our research provides a platform to enable focused future efforts to improve patient and public involvement in trials and enhance the relevance of statistical analyses to patients and the public.

Published: December 2023

Under the influence of natural weathering and excavation in human engineering, slopes in nature have various slope shapes. In human engineering activities, the stability of different types of slopes formed by manual excavation must be affected by multiple factors such as geologic setting, lithology and environment. Therefore, to understand the impact of slope shape, geologic setting, and other conditions on slope stability of artificial slopes, calculation models for straight slope, concave slope, and convex slope are constructed based on the three slope shape characteristics. By changing the angles of upward and downward slope angles and analysing the parameters of slope shape, joint spacing, and joint angle, discrete element software is used to calculate the slope safety factor. The calculation results show that the slope shape, joint spacing, and joint inclination affect the safety of slopes. In straight slopes with large joint spacing, the smaller the slope angle, the greater the safety factor. However, in the interval of small joint spacing, the safety coefficient of slopes with slight joint inclination has the opposite variation characteristics. When a<90°, the straight slope has a dominant joint inclination angle that minimises the slope safety factor. In concave slopes, the more concave the slope shape is, the smaller the safety factor is; For concave slopes with small joint spacing, the slope with slight joint inclination has a more significant safety factor; Under the condition of large joint spacing, there is a dominant joint inclination in the joint inclination range of 30° to 70° for concave slopes, which minimises the safety factor of the slope. In convex slopes, the smaller the joint inclination angle of the slope, the smaller the safety factor of the slope, and the smaller the upslope angle of the slope, the greater the safety factor of the slope.

Hepatitis E virus (HEV) is one of the leading acute liver infections triggered by viral hepatitis. Patients infected with HEV usually recover and the annual death rate is negligible. Currently, there is no HEV licensed vaccine available globally. This study was carried out to design a multi-epitope HEV peptide-based vaccine by retrieving already experimentally validated epitopes from ViPR database leading to epitope prioritization. Epitopes selected as potential vaccine candidates were non-allergen, immunogenic, soluble, non-toxic and IFN gamma positive. The epitopes were linked together by AAY linkers and the linker EAAAK was used to join adjuvant with epitopes. Toll-like receptor (TLR)-4 agonist was used as an adjuvant to boost efficacy of the vaccine. Furthermore, codon optimization followed by disulfide engineering was performed to analyse the designed vaccine’s structural stability. Computational modeling of the immune simulation was done to examine the immune response against the vaccine. The designed vaccine construct was docked with TLR-3 receptor for their interactions and then subjected to molecular dynamic simulations. The vaccine model was examined computationally towards the capability of inducing immune responses which showed the induction of both humoral and cell mediated immunity. Taken together, our study suggests an In-silico designed HEV based multi-epitope peptide-based vaccine (MEPV) that needs to be examined in the wet lab-based data that can help to develop a potential vaccine against HEV.
Exploring the nexus between physical environments, resident preferences, and usage frequency of community centers: Evidence from two Korean neighborhoods in Seoul
Authors: Yu Chia-Yuan , Woo Ayoung
Published: December 2023

Community centers offer a public space for physical activities, attracting residents with diverse interests and abilities, and promoting social interaction and connection, which in turn enhances individuals’ physical and mental fitness and fosters a sense of community. When exploring the correlation between community space accessibility and usage frequency, it is crucial to consider empirical evidence and resident preferences. Nevertheless, the role of physical environments in determining community center usage frequency, while also considering residents’ inclination for effortless access, remains unclear. This study investigated the impact of resident preferences and satisfaction with the accessibility of community centers and physical environments on usage frequency, addressing a gap in previous research. Structural equation models were utilized to analyze a household drop-off survey consisting of 186 residents gathered from two neighborhoods in Korea. The results revealed that while the preference for easy access to community centers did not have a substantial effect on their usage frequency, satisfaction with easy access to such centers was positively linked to usage frequency. Furthermore, the perception of physical environments as being walkable and having a diverse range of amenities was associated with a higher frequency of community center usage. These findings have policy implications as they can help increase the usage frequency of community centers and enhance overall well-being in regenerated neighborhoods.
Expanding the UTAUT2 framework to determine the drivers of mobile shopping behaviour among older adults
Authors: Huang Tianyang
Published: December 2023

In the current severe aging of the population, the problem of "digital divide" of the elderly has become increasingly prominent, and the elderly market represents a vast demographic that is increasingly becoming an important customer segment for mobile shopping in the future. However, there is currently insufficient attention given to the research on mobile shopping behavior among older adults. This study tries to answer what are the driving factors of mobile phone shopping behavior among the elderly? The purpose of this study is to analyze the factors that drive the elderly’s mobile phone shopping behavior, and to establish a mobile phone shopping acceptance model for the elderly to predict the factors of the elderly’s behavioral intention of using smart phones. Based on the second edition of Unified Theory of Acceptance and Use of Technology theory (UTAUT 2), this study proposed a mobile phone shopping acceptance model for the elderly. The study collected valid data from 389 Chinese elderly people through questionnaires and analyzed them using structural equation models. The results showed that utilitarian, anxiety, trust, performance expectancy, effort expectancy, social influence, facilitating conditions and habit directly impact the older adults’ intention to engage in mobile shopping. Additionally, facilitating conditions, habit and the older adults’ intention to engage in mobile shopping act as driving factors for actual use behavior. This study further expands the UTAUT theoretical model, provides a theoretical basis for the research of mobile shopping behavior of the elderly, and enricues the application groups and fields of the UTAUT theoretical model. The results of this study provide inspiration for the development, design and marketing of age-appropriate mobile shopping products, and contribute to the realization and further adoption of age-appropriate mobile shopping, and also contribute to promoting the active aging of the elderly.
Human arm endpoint-impedance in rhythmic human-robot interaction exhibits cyclic variations
Authors: Fortineau Vincent , Siegler Isabelle A. , Makarov Maria , Rodriguez-Ayerbe Pedro
Published: December 2023

Estimating the human endpoint-impedance interacting with a physical environment provides insights into goal-directed human movements during physical interactions. This work examined the endpoint-impedance of the upper limb during a hybrid ball-bouncing task with simulated haptic feedback while participants manipulated an admittance-controlled robot. Two experiments implemented a force-perturbation method to estimate the endpoint parameters of 31 participants. Experimental conditions of the ball-bouncing task were simulated in a digital environment. One experiment studied the influence of the target height, while the other explored the impedance at three cyclic phases of the rhythmic movement induced by the task. The participants’ performances were analyzed and clustered to establish a potential influence of endpoint impedance on performance in the ball-bouncing task. Results showed that endpoint-impedance parameters ranged from 45 to 445 N/m, 2.2 to 17.5 Ns/m, and 227 to 893 g for the stiffness, damping, and mass, respectively. Results did not support such a critical role of endpoint impedance in performance. Nevertheless, the three endpoint-impedance parameters described significant variations throughout the arm cycle. The stiffness is linked to a quasi-linear increase, with a maximum value reached before the ball impacts. The observed damping and mass cyclic variations seemed to be caused by geometric and kinematic variations. Although this study reveals rapid and within-cycles variations of endpoint-impedance parameters, no direct relationship between endpoint-impedance values and performance levels in ball-bouncing could be found.

Dispositivos de geolocalización de la persona trabajadora y despido disciplinario
Authors: López Fernández Rubén
Published: December 2023

El avance vertiginoso de las nuevas tecnologías de la información y la comunicación hace largo que viene transformando el mundo del trabajo. A la par que ofrece un sinfín de posibilidades técnicas al servicio de la flexibilización de las relaciones laborales, permite al empresario controlar el desempeño de sus empleados durante el horario pactado en contrato e incluso fuera de este. Como se sabe, el art. 20.3 ET le habilita para adoptar las medidas que considere oportunas en el ejercicio de sus funciones de control, siendo los sistemas de geolocalización una herramienta que no ha quedado exenta de controversias. Así las cosas, el interrogante principal es hasta dónde puede llegar la fiscalización empresarial respecto del cumplimiento de las obligaciones de sus trabajadores, si lo que se pretende es ejercer la máxima expresión de la potestad disciplinaria, esto es, el despido. Y en ese cruce de derechos fundamentales —libertad de empresa, intimidad y protección de datos personales— se erige como criterio fronterizo entre lo lícito e ilícito la información previa, que ha de ser expresa, clara e inequívoca para los trabajadores, e indicar la existencia y características de tales dispositivos. Al estudio de los pormenores de la recién referida cuestión se van a dedicar las siguientes páginas, para, finalmente, intentar exponer las conclusiones alcanzadas.
Transición digital y seguridad y salud en el trabajo: el AENC 2023 y el futuro de la negociación colectiva
Authors: Igartua Miró María Teresa
Published: December 2023

El AENC merece una primera valoración positiva desde el momento en que la seguridad y salud ocupa un lugar destacado, con un contenido más preciso que en versiones precedentes; asimismo, por afrontar la desconexión digital. No obstante, pueden apreciarse algunas carencias, un enfoque poco transversal de la seguridad y salud y débil enlace con la transición digital. Sorprenden algunos planteamientos algo “alejados” de la regulación legal, susceptibles de consolidar ciertas inercias y desajustes en la práctica negocial, que debe afrontar de manera decidida los desafíos para la seguridad y salud del desarrollo tecnológico.

Published: December 2023

En el presente trabajo se analiza el V Acuerdo para el Empleo y la Negociación Colectiva tomando en consideración la trayectoria de los acuerdos interconfederales y, especialmente, su contextualización en un proceso más amplio de diálogo social, incluyendo el tripartismo. Así, se estudian las innovaciones del acuerdo y su interrelación con la reforma laboral de 2021. En este sentido, el análisis destaca la recuperación de la centralidad de la negociación colectiva sectorial, en concordancia con lo previamente acordado en el diálogo social tripartito. También, se llama a atención del abandono de la política de moderación salarial, poniendo el acento en la recuperación del poder adquisitivo de los salarios. Finalmente, más allá del diálogo con el Gobierno, los agentes sociales han dedicado una parte importante a las transiciones digital, tecnológica y ecológica, planteándose en el trabajo la falta de ambición en el tratamiento de contenidos respecto de ésta última.

Authors: Mościcka-Teske Agnieszka , Sadłowska-Wrzesińska Joanna , Gajsek Brigita , Stachowiak Agnieszka
Published: December 2023

Purpose: The main objective of the research was to identify the structure and level of psychosocial risk experienced by transport workers and the relation between occupational stress and the decision to leave the job. Methodology: The research on psychosocial risks at work and their impact on job-related decisions was conducted with the Psychosocial Risk Scale (SRP), a scientifically verified diagnostic tool characterized by high reliability and accuracy of coefficients. The scale consists of four parts, A, B, C, and D. Part A concerns demographic data (such as age, gender, seniority, position, etc.). Part B contains questions related to health and professional functioning. Part C consists of 50 statements related to characteristics of work that pose potential psychosocial risks. Annex D-SRP for the transport sector contains 12 questions (α-Cronbach factor = 0.80). Psychometric properties of parts B and C of the Psychosocial Risk Scale were determined on the basis of the survey results. Results: The psychosocial risk categories considered were workload, job content, work schedule, control, environment and equipment, organizational culture and function, interpersonal relationships, career development, and work-life interface. The mediating effect of job satisfaction was also considered to provide a holistic perception of the analyzed problem. Job satisfaction was analyzed in job content, work conditions and organization, financial conditions, career development, and interpersonal relations with superiors and co-workers. Based on research results, authors identified and characterized the impact of psychosocial risk on transport workers' job-related decisions. Theoretical contribution: The research links social sciences, psychology, and management studies exploring the links between occupational stress and HR management implications, filling in a research gap between occupational stress and logistics management and creating new gaps and research questions as conclusions from research open following research fields and opportunities in the context of research on sustainable development of enterprises. It adds a new perspective to transport management, proving that risk resulting from job characteristics and organization can compromise the availability of workers and the quality of processes performed. Practical implications: The research results can be used by HR managers and workload planners to minimize the occupational stress experienced and improve the well-being and performance of transport workers.
SAW-Induced Spin Wave Excitation in Ferromagnetic Epitaxial Thin Films

Published: December 2023

Studying the collective excitations of the spin structure (magnons) in highly ordered materials like epitaxial thin films is an interresting field and offers an insight in the magnertic properties of new materials.Surface Acoustic Waves (SAW) have recently been used to study the phonon-magnon-coupling in for example thin films of Nickel evaporated on piezoelectric substrate material like LiNbO3.More interesting material classes, e.g. valence transition compounds, are usually grown on specially selected substrates to get highly ordered, epitaxial thin films with a specific lattice constant to achieve fine-tuned biaxial tensions which affect the magnetic properties.These substrates are usually non-piezoelectric and the phonon-magnon coupling can't be studied easily. Here we show a procedure that can be used to apply the well established SAW-based methods for the investigation of magnon spectra of epitaxial thin films grown on non-piezoelectric substrates.Using reactive RF sputtering methods, piezoelecxtric thin films can be applied on various non-piezoelectric substrates for the excitation of SAW in these substrates.A carefully coordinated sequence of reactive RF-sputtering, patterning and etching ensures best possible preservation of sensitive thin films.Measurments on well known Nickel thin films are shown as a reference.Further data of more exotic valence transition compounds measured at low temperatures are presented.The presented technique can be adapted by typically equipped thin-film laboratories without further costly investments and thus allows highly-sensitive measurements of the magnon spectrum of thin-film materials in the range of up to ~3 GHz (depending on the quality of available lithography equipment).

Published: December 2023

In this work, we have proposed a model that can detect emergency cars on a heavy traffic road. A populated region like Kurdistan faces too much traffic on the road and because of that emergency car like ambulance and fire-service fall into trouble middle of the road. Our model will solve this problem. It can be embedded with CCTV to track emergency can and give priority in that road to pass the emergency can. With this automated process, no human effort will be required to manually help such scenario. In our project we used a customized Yolov5 object detection algorithm. YOLO an acronym for (You Only Look Once), it is an object detection algorithm that divides images into a grid system. Each cell within the grid is responsible for detecting objects within itself. YOLO models are used for Object detection with high performance which consists of 84 classes to detect and differentiate between 84 different objects. Our model is based on 4 classes which are (Firetrucks, Ambulance, Police Car, and Normal Cars) classes. Our model has achieved impressing results in detecting and identifying emergency cars of all kinds, for Police Cars we have the result of 98%, for Fire Trucks 96%, for Ambulances we’ve got 89% and for Normal Cars 97% results.
Tradição e política na produção memorialística de Cyro dos Anjos
Authors: De Queiroz Porto César Henrique
Published: December 2023

Cyro dos Anjos, escritor montesclarense, escreveu um importante relato memorialístico intitulado A menina do sobrado. A primeira parte desse livro, chamada de Explorações no tempo: memórias, rememora com uma boa riqueza de detalhes aspectos do cotidiano de Montes Claros entre os anos de 1910 e 1923. A proposta deste texto é descortinar, a partir daí, aspectos da cultura política local no período em questão. Acima de tudo, pretende-se identificar como a cidade era representada na memória do autor, quando, apesar da política coronelista vigente, as elites locais viam Montes Claros como progressista.

Published: December 2023

Dentre as ações adotadas para o fortalecimento da atenção básica de saúde, destaca-se o Programa Mais Médicos (PMM), que consiste em uma iniciativa intersetorial que contempla uma série de medidas para o fortalecimento e consolidação da atenção básica. A expectativa de eficiência e bom desempenho do programa reside sobre o sucesso de sua lógica programática de implementação. Assim, esse estudo teve como objetivo central, entender como é o PMM em sua concepção teórico-pragmática e analisar a sua implementação no nível local, a partir da perspectiva de arranjos institucionais. Para isso, foi realizada uma análise documental para o resgate da teoria do PMM, em conjunto com entrevistas semiestruturadas com atores responsáveis pelo Programa no nível local, visando compreender a prática de execução. A partir das análises realizadas para o eixo de provimento emergencial, percebeu-se que o PMM, por ser uma política centralizada, é implementado de acordo com sua teoria, porém revela a falta de autonomia local para adaptá-lo às necessidades locais. Os resultados revelam uma política top-down, que tem entre os principais efeitos colaterais, as limitações no processo de comunicação, especialmente na fase de implementação da política. Isso expõe o papel coadjuvante da administração local, limitando-a na organização da relação do profissional de saúde com as necessidades locais.
trama de uma extensão sentipensante

Published: December 2023

Esta narração nasce de desassossegos que emergem do ser extensionista em um Centro Universitário, no município de Petrópolis, Rio de Janeiro. No encontro com gentes das classes populares, se evidenciou um jeito próprio de fazer extensão. Uma extensão fundamentada em uma prática dialógica, que se coloca à deriva no caminho, se expõe ao encontro e às mudanças que acontecem em decorrência das interações. Uma extensão que se compromete com essas gentes, na transformação do mundo. O exercício investigativo foi delineado metodologicamente como uma pesquisa com o cotidiano. O diálogo e a escuta são procedimentos que potencializam suas reflexões, tecidas por meio de registros de campo combinando a razão e o amor, o corpo e o coração, atuando a partir do diálogo amoroso, buscando o que poderia se chamar uma extensão sentipensante. Aposta no paradigma indiciário proposto por Ginzburg para captar pistas e indícios presentes nas vozes, nos gestos e nos silêncios das gentes da pesquisa. Com esse trabalho, se aprendeu que é possível uma extensão comprometida, amorosa e libertadora, que atue nas frestas desse modelo hegemônico de universidade, que subalterniza, exclui e provoca apagamentos de saberes, experiências e histórias.

O presente artigo tem como pretensão esboçar uma reconstituição histórica do processo de configuração do campo da educação popular no Brasil, compreendendo a sua trajetória e o seu desenvolvimento teórico-conceitual desde a década de 1950 até a contemporaneidade. Trata-se de um estudo de abordagem qualitativa, construído a partir de uma pesquisa bibliográfica com característica descritiva que se fundamentou na modalidade de revisão narrativa. Como resultado, caracterizam-se diferentes experiências e momentos históricos da educação popular no Brasil, a exemplo: a) da sua gênese ao processo de desarticulação de experiências; b) do acirramento da repressão decorrente da ditatura civil-militar ao espraiamento das práticas por diferentes setores; c) da eclosão de novas pautas à reinvenção do campo da educação popular; d) das conquistas políticas aos desafios institucionais. Em seguida, busca-se delinear uma possível caracterização do que vem a ser a educação popular em sua multiplicidade de perspectivas. Por fim, conclui-se que, para além da compreensão da educação popular como prática político-pedagógica, se sobressaem entendimentos dessa como teoria, campo de construção de conhecimentos, movimento organizado da sociedade civil e política pública.

A Educação Popular em Saúde (EPS) é importante para o empoderamento do cidadão em relação à saúde, todavia, parece haver um abismo em relação à comunicação entre profissionais de saúde e população. O presente estudo objetiva analisar o conhecimento dos discentes do curso de Fisioterapia na Universidade Federal de Pernambuco (UFPE) acerca da EPS. Trata-se de um estudo qualitativo em que discentes com vínculo ativo no curso foram recrutados. Os participantes foram orientados a ler o tema indutor “EPS” e associar as cinco primeiras palavras que lhe vinham à mente. A coleta das informações foi realizada de forma remota, por meio da plataforma Google Forms e analisadas pelo software Iramuteq. A amostra final foi composta por 49 discentes de todos os dez períodos do curso. As palavras mais citadas pelos discentes foram: “prevenção”, “Sistema Único de Saúde (SUS)”, “não sei/não lembro”, “conhecimento” e “saúde coletiva”. Diante disso, apesar dos futuros fisioterapeutas terem contato e reconhecerem a temática da EPS, os termos associados a ela ainda se apresentam de uma forma reducionista. Os resultados apontam a necessidade de estratégias que possam fomentar o conhecimento a respeito da EPS como forma de alcance de uma transformação social.
A sistematização de experiências e sua dimensão histórica na educação popular
Authors: Pitano Sandro de Castro , Moreira Janine
Published: December 2023

Esta entrevista oportuniza conhecer a trajetória de Elza Maria Fonseca Falkembach pelos caminhos da Educação Popular e, mais detidamente, da Sistematização de Experiências, de modo a apresentar os desafios inerentes, os princípios fundamentais e como se situa em relação ao campo da Educação Popular, sobretudo nas dimensões ética, política e epistemológica. Aborda a questão da produção de subjetividades (no sentido singular e coletivo), que é muito presente na Sistematização de Experiências, e a remete à decolonialidade. E finaliza com a reflexão em torno da identificação da sistematização como um processo aprofundado de avaliação sobre uma determinada experiência, o que contribui, também, para pensarmos na relação entre a Sistematização de Experiências e a pesquisa acadêmica nas universidades.
A educação popular no início do século 21
Authors: Torres Carrillo Alfonso
Published: December 2023

O artigo problematiza a heterogeneidade dos campos de atuação, sujeitos e práticas que caracterizaram as práticas de EP ao longo da sua história, de modo a identificar um núcleo de sentido associado a um conjunto de características que lhes conferem singularidade e as diferenciam de outras práticas pedagógicas. Essas características, problematizadas ao longo do texto, também estão presentes em outras práticas culturais, com as quais a educação popular interagiu historicamente, como a igreja popular, a teologia da libertação, a comunicação popular e a pesquisa participativa.

Las clases expositivas se caracterizan por un escaso intercambio verbal comunicativo, la búsqueda de estrategias que modifiquen las interacciones entre docentes y estudiantes ha sido una característica de la cátedra de Toxicología, Farmacología y Bioquímica Legal de la FBCB. Recuperando las vivencias de los entonces estudiantes de grado y auxiliares docentes buscamos recobrar la historia de las últimas décadas de una parte nuestra institución, sus metodologías, sus inquietudes y sus proyecciones al futuro. Estos docentes han generado producciones que se articularon con la realidad y con los intereses de sus estudiantes, han intentado promover la pasión por aprender, por hacer visibles los procesos de construcción del conocimiento.
Algunas experiencias pedagógicas a partir de la creación de la carrera de Terapia Ocupacional en la Universidad Nacional del Litoral (Santa Fe, 1985 - 2007)
Authors: Arriola de Mines Beatriz
Published: December 2023

En este artículo se recuperan, historizan y plantean como aportes para las prácticas pedagógicas actuales de la carrera de la Terapia Ocupacional las experiencias pedagógicas a partir de la creación de la misma desde la voz de la docente jubilada, asesora y creadora de la carrera, Beatriz Arriola de Mines. Las preguntas que vertebran el presente texto son, entre otras, las siguientes: ¿Por qué y para qué escribir un artículo sobre las experiencias, prácticas y saberes pedagógicos en torno a la carrera de Terapia Ocupacional? ¿Por qué puede significar un aporte a las problemáticas educativas universitarias? ¿Cómo se relacionan el origen, la especificidad del saber disciplinar de la Terapia Ocupacional con su enseñanza? ¿Con quiénes, en qué espacios (en el aula y más allá del aula) y de qué modos se enseña y se aprende en la carrera de Terapia Ocupacional? Y, por último, para cerrar el artículo, retomando esta última indagación se presenta una problematización en torno a las tradiciones, memorias y experiencias que se reconocen -y las que no- en la enseñanza de la carrera de Terapia Ocupacional.
Desarrollo de competencias profesionales e interculturales en Proyectos de Internacionalización Curricular de Carreras de Grado de UNL
Authors: Vargas Matías Rodrigo
Published: December 2023

La educación en general -y el nivel superior en particular- como organismo vivo dentro de las sociedades se vio fuertemente afectada por los procesos de globalización, encontrándose en la necesidad de formar profesionales competentes y adaptables a estos cambios mediante el proceso de internacionalización en los distintos niveles educativos. En este contexto, la Universidad Nacional del Litoral realiza el programa «Internacionalización de Espacios Curriculares de Carreras de Grado». El presente trabajo se propuso evaluar el desarrollo de competencias interculturales a partir de las actividades planificadas y desarrolladas en proyectos de internacionalización seleccionados en la convocatoria 2018, como componente dentro de estas experiencias curriculares. A su vez, se planteó estudiar el desarrollo de competencias profesionales en el marco de internacionalización curricular, y la articulación entre ambas categorías de competencias, interculturales y profesionales, por ser de esencial importancia en la formación integral del estudiantado.
¿Qué hacer ante la (des)protección de niños, niñas y adolescentes? Un tema debatido en el Grado en Historia
Authors: De Andrade Juliana Alves , Da Silva Miranda Humberto
Published: December 2023

Este artículo busca presentar una reflexión teórico-práctica sobre la experiencia de los futuros profesores de historia, graduados de la Universidad Federal Rural de Pernambuco (UFRPE), y los operadores de los derechos de los niños y adolescentes (Consejeros de Tutela) en Brasil. Un diálogo que permitió el desarrollo de una reflexión epistemológica sobre la enseñanza y las cuestiones sociales, especialmente la relación entre la enseñanza, la escuela y la red de protección de niños y adolescentes. En la primera parte, presentaremos el escenario de la práctica y la reflexión y la idea de una red de seguridad. En un segundo momento, presentamos un debate sobre cómo estos agentes se convirtieron en los principales articuladores entre la escuela, la comunidad y la red de protección de niños, niñas y adolescentes. A continuación, trataremos la escuela como un espacio de protección y el papel que puede desempeñar el profesor de historia para enfrentar la violencia y defender los derechos de los niños, niñas y adolescentes. Finalmente, señalamos algunos conocimientos y acciones necesarias para que el profesor enfrente los desafíos sociales del presente y del futuro en el espacio escolar brasileño, mostrando cómo tuvo lugar el diálogo de este fructífero encuentro pedagógico.
