Authors: Barnes Neil Abraham , Dkhar Winniecia , S Sharath , Chhaparwal Yogesh , Mayya Veena , H Roopitha C
Published: September 2024

Background Dental radiology has significantly benefited from cone-beam computed tomography (CBCT) because of its compact size and low radiation exposure. Canal tracking is an important application of CBCT for determining the relationship between the inferior alveolar nerve and third molar. Usually, canal tacking is performed manually, which takes a lot of time. This study aimed to develop an artificial intelligence (AI) model to automate classification of the mandibular canal in relation to the third molar. Methods This retrospective study was conducted using 434 CBCT images. 3D slicer software was used to annotate and classify the data into lingual, buccal, and inferior categories. Two convolution neural network models, AlexNet and ResNet50, were developed to classify this relationship. The study included 262 images for training and 172 images for testing, with the model performance evaluated by sensitivity, precision, and F1 score. Results The performance of the two models was evaluated using a 3 × 3 confusion matrix, with the data categorized into 3 clases: lingual, buccal, and inferior. The mandibular canal and third molar have a close anatomical relationship, highlighting the need for precise imaging in dental and surgical settings. To accurately classify the mandibular canal in relation to the third molar, both AlexNet and ResNet50 demonstrated high accuracy, with F1 scores ranging from 0.64 to 0.92 for different classes, with accuracy of 81% and 83%, respectively, for accurately classifying the mandibular canal in relation to the third molar. Conclusion The present study developed and evaluated AI models to accurately classify and establish the relationship between the mandibular canal and third molars using CBCT images with a higher accuracy rate.
Beyond resilience? A comparative sociological analysis of the impact of the Covid-19 pandemic on five European health care systems
Authors: Giarelli Guido , Mantineo Marilin
Published: September 2024

Background The article questions the popularity of resilience as a concept and its application to health care systems as a main lens for understanding the impact the COVID-19 pandemic on them. Methods It develops a sociological definition following a thorough examination of the various proposed meanings for the term. Subsequently, it proposes a conceptual framework to analyze the vulnerability and sustainability of health care systems as a more comprehensive tool that moves beyond the limitations of resilience. This framework is then applied to evaluate its heuristic value in assessing the resilience strategies adopted in response to the COVID-19 pandemic in five European countries (France, Hungary, Italy, Sweden, and the United Kingdom), considered as problematic ‘sentinel cases’ within their health macro-regions. Adopting the six variables provided by the COVID-19 Health Systems Response Monitor of the European Observatory on Health Systems and Policies, a detailed comparative analysis is conducted. This analysis explores the resilience strategies of these countries in terms of the vulnerability outputs they produced and their consequent effects on the sustainability of their health care systems. Results The results show that the resilience strategies adopted during the pandemic were shaped by the different configurations of health care systems and policy decisions regarding resource mobilization. As such, these strategies produced various vulnerability outputs, resulting in different degrees of risk distribution and sustainability. Conclusions These results are pertinent for understanding that what matters from a sociological point of view is not simply how different health care systems cope with external shocks like a pandemic to retain control over their structure and functions (resilience), but the social consequences produced by their strategies.
Cross-Sectional Association Between Life Expectancy and Unhealthy Life Years: Proof of Concept Tests of the CroHaM Hypothesis
Authors: Luy Marc
Published: September 2024

The recently presented CroHaM hypothesis says (1) that longitudinal health domain-specific expansion and compression effects depend primarily on the health domains’ mortality risk and (2) that these effects exist equivalently in the cross-sectional context, affecting differences in healthy life years (HLY) between populations and subpopulations with different levels of life expectancy (LE). We test this hypothesis by analysing the association between LE and unhealthy life years (ULY) at age 50 for a large number of subpopulations. The analyses are carried out for three health domains which are differently related to mortality: poor self-perceived health and strong activity limitation with comparatively high mortality, and chronic morbidity with comparatively low risk of dying. Data on gender- and subpopulation-specific prevalence of these health conditions are taken from the Actual German Health Study 2012 (GEDA). LEs are estimated with the “Longitudinal Survival Method”, using data of the German Life Expectancy Survey. ULY are estimated with the “Sullivan Method”. Differences in ULY between each subpopulation and the total population and between women and men for each subpopulation are decomposed into the effects caused by differences in health (“health effect”) and mortality (“mortality effect”) with the “Nusselder/Looman Method”. The results confirm the CroHaM hypothesis: we find a positive relationship between LE and ULY only for chronic morbidity, whereas this relationship is negative for poor self-perceived health and strong activity limitation. However, when the mortality effect is controlled for, we find a negative relationship between LE and ULY for all three health domains. The practical relevance of these findings is discussed using the example of the so-called “gender paradox” in health and mortality. We conclude that the CroHaM hypothesis may describe an important determinant of life years spent with and without health impairment, and it may help to better understand and interpret trends and differentials in HLY or ULY based on cross-sectional data.

Trade Union Practices and Working Conditions of Chambermaids.
Authors: Moral-Martín J. David , Ferri-Fuentevilla Elena , Estepa-Maestre Francisco
Published: September 2024

Historically, women’s domestic work in households has been the subject of academic study that dates back to the 18th and 19th centuries. But the specifi c work of chambermaids in hotels only began to be studied in the early 2000s. The aim of this study is to test the above hypothesis and to identify research that has been done on labour organization, working conditions and health of housekeepers. The methodology consists of systematically reviewing the contributions on this issue registered in indexed publications between 2000 and 2021. It is confi rmed that the fi rst publication is from 2003. Among the results, the tendency of housekeepers to selforganize, such as “Las Kellys” association in Spain, stands out. The international comparison indicates intersectionality of discriminating factors increasing their vulnerability. For example, forms of piecerate payment are linked to higher accident rates, subcontracting increases and future automation could have a negative impact on labour negotiation. On the positive side, it is hoped that sustainable tourism labels will encourage decent working conditions for hotel housekeepers.

Jiwa merupakan salah satu unsur yang membentuk kesehatan pada manusia. Jiwa yang sehat membuat seorang individu mampu mengembangkan dirinya secara fisik, mental, spiritual dan sosial. Ketika seseorang memasuki usia produktif, yaitu 15-64 tahun, seharusnya ia bisa memaksimalkan pengembangan potensi dirinya. Akan tetapi justru di rentang usia ini bermunculan permasalahan yang bersumber dari jiwa yang tidak sehat, mulai dari tingkat ringan hingga yang paling berat, yaitu tindakan bunuh diri. Sebagaimana laiknya penyakit yang lain, gangguan kesehatan jiwa bisa tertangani dengan baik atau tingkat harapan kesembuhannya meningkat jika permasalahannya bisa terdeteksi sejak dini. Pada umumnya pasien tidak mendapatkan penanganan yang baik karena dia tidak mengetahui bahwa gejala-gejala yang dimilikinya mengindikasikan penyakit kejiwaan, cenderung meremehkan, atau khawatir mendapat stigma yang buruk dari masyarakat. Melalui sebuah seminar tentang pengelolaan stress dan deteksi dini, mahasiswa sebagai bagian dari angkatan usia produktif mendapatkan pembekalan tentang tanda-tanda gangguan kesehatan mental, penyebab dan penanganannya.

Lithium disilicate glass-ceramic (LDS) is increasingly being adopted for use in therapeutic restorative procedures. Concurrently, zirconia-reinforced silicate glassceramics (ZRS) are becoming broadly utilized in dental applications. The purpose of this study was to evaluate and compare the mechanical properties of zirconia-reinforced lithium silicate glass-ceramics and lithium disilicate-based glass-ceramics, with a focus on their application in CAD/CAM technologies. In this review, the researchers conducted a search of the PubMed (MEDLINE) database to identify studies related to LDS and ZRS. This search was limited to articles published in English over a seven-year period, from January 1, 2015, to December 31, 2022. Additional studies were sourced from Google Scholar and through manual exploration. Key published works were identified and included in the literature review. The findings concluded that ZRS exhibits superior mechanical properties, including higher flexural strength, fracture toughness, and hardness, compared to LDS. Furthermore, ZRS combines desirable esthetic qualities with robust mechanical strength, rendering it an excellent material for single tooth aesthetic restorations such as inlays, onlays, crowns, and veneers, applicable to both tooth and implant supports. Currently, there is a notable scarcity of data concerning the mechanical properties and clinical efficacy of ZRS. Therefore, it is imperative to conduct long-term clinical studies to verify the optical and mechanical properties, clinical applications, limitations, and long-term effectiveness of ZRS.

Objectives: This study aimed to evaluate the remineralization efficacy of nano-strontium/ fluoride hydroxyapatite paste on initial enamel caries in comparison with other remineralization products under a simulated pH-cycling model. Methods: Following the artificial caries induction, forty enamel specimens with noncavitated lesion in the same range of lesion depth were selected by mean of micro-CT evaluation. The specimens were block-randomized into four experimental groups regarding remineralizing pastes: 1500 ppm sodium fluoride paste, 10%wt nano-hydroxyapatite paste, 10%wt nano-strontium/fluoride hydroxyapatite paste and 5%wt nano-strontium/ fluoride hydroxyapatite paste. Remineralizing effect was evaluated using micro-CT, while SEM/EDS line scan mode facilitated the investigation of remineralization patterns. Changes in lesion depth (ΔLD) and changes in mineral loss (ΔΔZ) were evaluated at 7 and 14 days of treatment under the pH-cycling model. Statistical analyses were performed using 2-way ANOVA and post hoc Tukey’s test (p<0.05). Results: The use of 5%wt nano-strontium/fluoride hydroxyapatite paste significantly reduced lesion depth in initial caries under experimental conditions. Meanwhile, the 10%wt nano-strontium/fluoride hydroxyapatite paste yielded the highest mineral gain, though statistically insignificant. EDS graphs indicated an increasing calcium and phosphorus deposition trend over time with nano-strontium/fluoride hydroxyapatite paste, revealing a more uniform mineral distribution compared to both sodium fluoride and nano-hydroxyapatite pastes. Nevertheless, neither fluorine nor strontium was detectable in these graphs. Conclusions: The study revealed comparable remineralization efficacy with 5%wt and 10%wt nano-strontium/fluoride hydroxyapatite pastes. The treatment durations of 7 and 14 days showed no significant difference in outcomes.
Towards a compact soliton microcomb fully referenced on atomic reference

Published: September 2024

In this work, we propose a simple architecture for achieving an atomic-referenced fully stabilized soliton comb based on MgF2 microresonators. In the scheme, we directly utilize a laser as the pump source, with its frequency (fp) locked to the optical frequency reference of a rubidium 5S-5D two-photon transition, and mechanically control the resonator’s length with a piezoelectric ceramic (PZT) to generate solitons. With the thermal compensation from a resonance close to the soliton mode, we can easily maintain the soliton state and then successfully phase-lock the soliton’s repetition frequency (frep) to a radio frequency (RF) reference by PZT. This method described allows for no coupling between fp and frep. Unlike previous solutions, our implementation does not require any AOM or EOM optoelectronic devices, auxiliary lasers, or optical frequency phase-locking loops and a decoupled strategy for locking parameters, which typically increase the system’s complexity and reduce its compactness. Our results confirm that the stability of a comb line, positioned approximately 0.66 THz from the pump source, aligns with the stability of the Rb optical reference, achieving a remarkable precision of approximately 4 Hz over 100 seconds. Moreover, we examined the frequency repeatability of the comb line over six days, achieving a frequency standard deviation of about 10 kHz, which marks the highest level ever reported for atom-reference soliton microcombs. Our approach offers a low-power, compact alternative for fully stabilizing soliton microcombs, providing a more practical and efficient option compared to conventional methods.
Model analysis for optical frequency comb Faraday modulation rotation spectroscopy
Authors: Xu Ze , Zhu Ning , Song Zihao , Wang Weitian , Chao Xing
Published: September 2024

Modulating the signal is a common method in spectroscopy for reducing noise. However, for broadband coherent light sources like optical frequency combs (OFCs), modulation methods typically involve the use of optical modulators, making the experimental setup cumbersome. This study proposes and successfully implements a broadband Faraday modulation rotation spectroscopy (FAMOS) method combined with an OFC. The development of this method by extending the modulation frequency of the OFC from tens of MHz down to the kHz level, effectively relaxes the stringent demands for high-speed electronics and optoelectronic devices, making modulation spectroscopy techniques more practically useful for diverse real-world environments. Moreover, through specifically designed modulation strategies, this method can effectively suppress low-frequency noise, thereby significantly improving the signal-to-noise ratio of the measurements without sacrificing measurement accuracy.
Model based optimization for refractive index mismatched light sheet imaging
Authors: Sheppard Steven J. , Brown Peter T. , Shepherd Douglas P.
Published: September 2024

Selective plane illumination microscopy (SPIM) is an optical sectioning imaging approach based on orthogonal light pathways for excitation and detection. The excitation pathway has an inverse relation between the optical sectioning strength and the effective field of view (FOV). Multiple approaches exist to extend the effective FOV, and here we focus on remote focusing to axially scan the light sheet, synchronized with a CMOS camera’s rolling shutter. A typical axially scanned SPIM configuration for imaging large samples utilizes a tunable optic for remote focusing, paired with air objectives focused into higher refractive index media. To quantitatively explore the effect of remote focus choices and sample space refractive index mismatch on light sheet intensity distributions, we developed an open-source computational approach for integrating ray tracing and field propagation. We validate our model’s performance against experimental light sheet profiles for various SPIM configurations. Our findings indicate that optimizing the position of the sample chamber relative to the excitation optics can enhance image quality by balancing aberrations induced by refractive index mismatch. We validate this prediction using a home-built, large sample axially scanned SPIM configuration and calibration samples. Our open-source, extensible modeling software can easily extend to explore optimal imaging configurations in diverse light sheet imaging settings.

Published: September 2024

Arbitrarily designed resonant-based metasurfaces are particularly attractive and present a unique platform for biosensing applications owing to their ability to confine light to nanoscale regions and their spectral selectivity. In this study, we experimentally demonstrate a metasurface sensor based on terahertz fingerprint spectroscopy that enables the specific recognition of trace samples. The results of simulations and experiments show that this metasurface sensor detects glycine, L-arginine, and L-threonine, respectively, with different resonance coupling. The frequency shift of the resonance peak of the metasurface sensor was the largest when the resonance peak matched the fingerprint peak of the sample, with a maximum of 123 GHz for detecting L-threonine. Therefore, combining the frequency shift of the resonance peaks with the fingerprint spectrum of the sample can achieve specific recognition of the sample. This study provides new ideas for specific recognition of samples using metasurface sensors in biomedicine, food safety, and other fields.
Quantum mechanics to classical mechanics boundary:
N-slit heavy-atom interferometer
Authors: Duarte Francisco
Published: September 2024

The question of when quantum mechanics becomes classical mechanics is considered from an N-slit interferometric perspective. In this regard, the design of an N-slit heavy-atom interferometer is depicted and discussed. This work includes a conceptual and experimental discussion of the Diósi-Penrose hypothesis. Such hypothesis is found to be decoupled from the interferometric foundations of quantum mechanics. For the boundary situation beyond which interference, for heavy-atom aggregates, is no longer viable, a minimalist principle is suggested: spontaneous nonsuperposition, at the probability amplitude level. This is proposed as onset for the quantum → classical transition. Further, a more pragmatic highly indeterministic mechanism is also considered.

Unconditional energy conservation and conditional regularity for the incompressible Navier-Stokes Maxwell system
Authors: Ma Dandan , Wu Fan
Published: September 2024

In this paper, we study a hydrodynamic system modeling the evolution of a plasma subject to a self-induced electromagnetic Lorentz force in incompressible viscous fluids. The system consists of the Navier–Stokes equations coupled with a Maxwell equation. In the three dimensional case, we show that every weak solution verifies the energy equality for the incompressible Navier–Stokes–Maxwell equations with damping. We also establish some non-explosion criteria in terms of the velocity and magnetic of local strong solution for standard Navier–Stokes–Maxwell system.

This note is a reaction on a recently published sufficient condition for oscillation of all solutions of a neutral delay differential equation. It is shown by a counterexample that the result is not correct and the problem is explained in details. Several, more general, classes of neutral differential equations with time-dependent discrete, distributed as well as mixed delays are considered. New sufficient conditions for oscillation of all their solutions are proved. Applications are given for illustration.
Profile of Ocular Trauma in Pediatric Population in a Tertiary Care Hospital
Authors: Samson Rajpal  , Nitin Batra  , Gurvinder Kaur
Published: September 2024

BACKGROUND
Ocular trauma is the major cause for preventable monocular blindness and visual impairment worldwide. It accounts for 8%-14% of total injuries in the pediatric age group. Various studies have shown its higher incidence in this age group. They have different patterns of ocular injuries than adults and have age specific type of injuries. The number of blind years that a child lives with compared to an adult is far more. Most of the previous studies have been on ocular trauma among the adult population, specifically the factory workers in the city of Ludhiana. Moreover, this study aimed to derive a relation between the time of presentation from the injury and the final visual outcome which has rarely been reported in other studies. Profile of ocular trauma in an area is a dynamic and ever changing trend. Therefore, we proposed to study the profile of ocular trauma in pediatric population presenting to our hospital.
METHODS
A total of 60 patients between the age of 0 to 17 years were included in this study. The study was conducted from 15th December 2020 to 31st May 2022. Complete ocular examination was done at the time of presentation and after management; The best corrected visual acuity was noted at the end of three months.
RESULTS
Among our study subjects 45% belonged to the age group of 11-17 years. A male predominance (68.3%) was noted. For most of the subjects, the duration between time of injury and time of examination was less than 6 hours. The proportion of closed globe type of injury (80%) was significantly higher as compared to open globe (8.3%) and extraocular type of injury (11.7%). At the 3 month follow up, out of the 53 study subjects, 92.45% had good visual outcome (VO), 3.77% had fair VO and 3.77% had poor VO respectively.
CONCLUSIONS
Most of the pediatric ocular trauma may be avoided, which emphasizes the value of health education, adult supervision, and the implementation of suitable interventions to lessen the frequency and severity of trauma. Better visual outcome is expected with a shorter duration between time of injury and time of presentation.
A Challenging Diagnosis - Large Leiomyomas on Rudimentary Uterus in Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome
Authors: Hema Divakar  , Rita Singh  , Poorni Narayanan  , Pallavi Suresh Pushpa  , Gubbi Venkatasubbaiah Divakar
Published: September 2024

A 40-year-old woman diagnosed with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome at 16 years of age presented with a large abdominal mass protruding to the right subcostal margin, equivalent to 30 weeks gestation. She didn’t have comorbidities of hypertension or diabetes. The vitals were normal with BMI 30. She was asymptomatic except for occasional vague abdominal discomfort. Further imaging studies were conducted to assess the extent and nature of the findings. Pelvic and transvaginal ultrasound demonstrated the presence of multiple large fibroids extending beyond the level of the umbilicus. This was corroborated by pelvic MRI, which further confirmed the massively enlarged multi-fibroid uterus. Additionally, intravenous contrast-enhanced imaging revealed large bilateral ovarian collaterals and prominent blood vessels extending to the broad ligament.
Triple-phase CT angiogram of the abdomen/pelvis with pre-contrast revealed an 8mm aneurysm on the anterior aspect of the abdominal aorta and unusual vascular anatomy, raising the possibility of an atypical or neoplastic process in the right iliac fossa. In view of these findings, an opinion by an Oncologist was sought, who suspected the possible presence of an abnormal nidus of vessels and a fluid attenuation area in the right iliac fossa. Additionally, the Risk of Ovarian Malignancy Algorithm (ROMA) test was performed, revealing a slightly elevated value. To reach the final diagnosis, the decision for the exploratory laparotomy was undertaken. Intraoperative findings revealed the presence of a rudimentary uterus with normal ovaries (Figure 1 and Figure 2), as well as the presence of bilateral broad fibroids (Figure 3). The broad ligament areas around the uterus were occupied with large circumscribed masses, identified as fibroids. The right-side fibroid measuring 17 x 15cm (Figure 4) and the left-side fibroid measuring 10 x 10cm (Figure 5) were excised, respectively, while preserving the left ovary and rudimentary uterus. Peritoneal fluid samples were obtained to ascertain the nature of malignancy. No evidence of infiltration or adhesions was detected.  Postoperatively, the patient experienced no complications. Histological examination of the masses growing from bilateral uterine remnants confirmed the presence of leiomyomas, with no glandular epithelium identified. Peritoneal fluid analysis revealed the absence of malignant cells.

RESUMO
A educação infantil e a educação física tiveram origens tecnicistas bem marcadas. Enquanto a primeira passou por um processo assistencialista, filantrópico, higienista e sanitarista até formatar-se pedagógica; a segunda seguiu por um trajeto higienista, militarista, esportivista até adotar uma abordagem crítica considerada produtora da cultura corporal de movimento. Como suas origens e trajetórias, outro ponto de convergência é a dialética do binômio cuidar e educar da educação infantil e da dicotomia corpo e mente da educação física. Utilizando-se do método biográfico, a partir da narrativa autobiográfica, o artigo buscou compreender o cuidar o corpo e o educar a mente nas aulas de educação física na educação infantil, ministrada por um professor Homem. Foi realizado um estudo qualitativo de revisão bibliográfica, com referencial teórico dos estudos de gênero e estudos feministas. O resultado encontrado é o reforço do patriarcado na tentativa de deslocamento do homem no ambiente da educação infantil.

Paralelo a isso, esse texto buscou desnaturalizar a identificação de gênero, por revisão de literatura, pautado em obras do Philippe Àries e Neil Postman, “História social da criança e da família (1981) e o Desaparecimento da infância (1999), respectivamente” para pensar a ideia de adolescência, assim como com as obras de Judith Butler e Paul Preciado: “Desfazendo Gênero (2004) e Eu sou o monstro que vos fala (2022), respectivamente” para discutirmos a ideia de gênero. Buscando um diálogo que possa transgredir a hegemonia de gênero que oprimiu e segue oprimindo outras formas de ser e estar no mundo. Os resultados mostraram que a invenção de gênero oprime, patologiza e cria necessidades reparatórias de adequação e subalternidade, assim como a Psicologia ocupou muitas vezes o lugar de um etnocentrismo e que é necessária a construção de uma Psicologia transgressora, que coadune com os direitos humanos.

Como parte de uma pesquisa coletiva realizada sobre o Programa de Gênero e Sexualidade da Escola de Aplicação da FEUSP, o presente texto narra o processo de produção de material formativo para docentes em vídeo, bem como a importância da divulgação de materiais diversos para se trabalhar temáticas sobre educação, gênero e sexualidade em escolas públicas brasileiras, compartilhando experiências e desafios. O Programa Gênero e Sexualidade da Escola de Aplicação da FEUSP foi criado no início dos anos 1990, de maneira precursora, com o nome de Orientação Sexual Adolescente. Desde então, tem desenvolvido diversas ações com estudantes, professores, bolsistas e estagiários, passando por desafios e transformações. Neste relato, narramos o processo de elaboração de uma série de três vídeos curtos com especialistas, docentes e pesquisadores da escola, publicada na plataforma Youtube, no esforço de divulgação científica e educacional no âmbito de um projeto temático.

O presente artigo tem como objetivo analisar opiniões da população LGBTQIAPN+ sobre ações afirmativas desenvolvidas por uma universidade pública para o acesso à educação e o combate à violência LGBTQIAPN+fóbica, sendo a exposição de um recorte de uma pesquisa mais ampla sobre demandas e qualidade de políticas e ações afirmativas de acordo com a população LGBTQIAPN+ universitária. Foi aplicado um questionário contendo questões para os participantes expressarem suas opiniões em relação às ações e políticas afirmativas universitárias. Os dados foram analisados com base nos princípios da pesquisa qualitativa. As informações levantadas indicam desconhecimento das ações desenvolvidas pela universidade por parte dos participantes, ao mesmo tempo que demandam ações adicionais que contemplem realidades vividas por LGBTQIAPN+. Com os resultados discutimos a avaliação das ações conhecidas, a manutenção do sistema cis/hétero no cotidiano universitário, demandas da população LGBTQIAPN+ e LGBTQIAPN+fobia no contexto universitário.
VIVÊNCIAS DE PESSOAS TRANGÊNERO NA EDUCAÇÃO BÁSICA

Neste trabalho, discutimos a respeito das vivências das pessoas trans na educação básica, com o objetivo de analisar suas experiências nas suas trajetórias escolares. Trata-se de uma revisão da literatura, de caráter descritivo, e de abordagem qualitativa. Selecionamos pesquisas que foram analisadas com base nas perspectivas pós-estruturalistas e na Teoria Queer, que também alicerçam o arcabouço teórico. As pesquisas sugerem que o espaço escolar é marcado por violências e discriminações que são oriundas, inclusive, de agentes escolares, e que, para os/as estudantes permanecerem no sistema de ensino, isolam-se e se anulam, como forma de se defender das violências. Concluímos que as pesquisas enfatizam a urgência de repensarmos o sistema de ensino e as práticas pedagógicas, para que, assim, possamos acolher a diversidade e respeitar a dignidade do/a estudante que rompe a norma cisheteronormativa.
O QUE UM FILME PODE FAZER CONOSCO E O QUE PODEMOS FAZER COM UM FILME? PRODUÇÕES DISCURSIVAS DE JOVENS NEGRAS SOBRE VIOLÊNCIA SEXUAL ACIONADAS POR MEIO DO LONGA-METRAGEM “PRECIOSA"
Authors: Santos Figueiredo Roniel , Lopes de Souza Marcos
Published: September 2024

Este artigo analisa as produções discursivas geradas por meio da exibição do longa metragem “Preciosa: uma história de esperança”, em uma turma de estudantes de uma escola estadual de ensino médio do interior baiano, nas atividades do componente curricular Núcleo de Estudos. As informações empíricas foram produzidas por meio de gravação de áudio das discussões e das anotações em um diário de campo. As análises destacaram que as estudantes negras se reconheceram na história de Preciosa e compartilharam, dentre outras coisas, os relatos de violência sexual que também sofreram. Sobre as estratégias de resistência às investidas de homens assediadores, algumas estudantes usaram do confronto para enfrentá-los. A exibição do artefato visual possibilitou a [re]configuração do núcleo de estudos como lugar de confiança e de dororidade, potencializando esse espaço curricular enquanto uma rede de apoio para as estudantes e também de problematização da violência sexual contra as mulheres negras.
BULLYING HOMOFÓBICO E O DESENVOLVIMENTO DO SELF DIALÓGICO
Authors: Neves Francisco , Uchoa Branco Angela
Published: September 2024

Nas escolas, estudantes homossexuais, e os que são assim percebidos, sofrem preconceito homofóbico, como piadas, apelidos, insinuações, xingamentos etc., que se configuram como bullying homofóbico. O artigo analisa as relações entre bullying e homofobia com base em artigos científicos nacionais e internacionais com as palavras-chave “bullying”, “homofobia”, e “bullying homofóbico”. Em todos os casos, verifica-se que a trajetória de jovens homossexuais é marcada por posicionamentos e contra-posicionamentos de si mobilizados pelo bullying homofóbico, e por fortes tensões que, segundo a Teoria do Self Dialógico-TSD, os leva ao sofrimento e dificuldades. Argumenta-se que a TDS consiste em produtiva perspectiva para a analisar a questão, e que temas como diversidade sexual e gênero devem ser incluídos e discutidos no currículo escolar, assim fomentando o respeito aos direitos humanos e à diversidade, e levando a escola a assumir sua responsabilidade em prevenir e desconstruir toda forma de preconceito.

O mecanismo de discriminação na sociedade nega direitos e cidadania plena, mantendo desigualdades e oprimindo grupos subalternizados. No ambiente escolar, essas discriminações se manifestam, exigindo uma abordagem ética e cuidadosa. Este artigo propõe uma didática intercultural, antirracista e antimachista para o ensino de português em ambientes multiculturais e plurilíngues, promovendo a interação entre estudantes brasileiros e hispano-falantes em Foz do Iguaçu, Paraná, Brasil. A proposta visa à Educação das Relações Étnico-raciais e de Gênero e em Direitos Humanos, fundamentada na teoria de letramento crítico de Paulo Freire (1987), pedagogia crítica intercultural de Catherine Walsh (2005-2006) e teorias antirracistas e antimachistas de intelectuais negros como Djamila Ribeiro (2019), Silvio Almeida (2019) e Carla Akotirene (2019). A metodologia se baseia na mediação de leitura literária de Sarah Hirschman (2011), destacando textos de mulheres, principalmente negras, para combater o racismo, machismo e xenofobia, promovendo uma educação reflexiva e adaptada à realidade escolar.
IGUALDADE DE OPORTUNIDADES?
Authors: Gomes Firmino Simone , Rosa Echeverría Agustina
Published: September 2024

Este artigo examina a "igualdade de oportunidades" no contexto neoliberal, abordando sua inserção na realidade social e a importância de explorar diferentes níveis de percepção desse conceito para compreender a realidade concreta. O objetivo é analisar como essa concepção se manifesta em práticas de segregação e discriminação baseadas em cor da pele, etnia e outros preconceitos. A pesquisa teórica, fundamentada em uma tese de doutorado de um Programa de Pós-Graduação em Educação em Ciências e Matemática de uma Universidade Federal, investiga a diversidade humana em contextos históricos e sociais. O artigo questiona como a concepção liberal de “igualdade de oportunidades” perpetua desigualdades sociais e discute a relação entre representações raciais, sistemas de (re)produção e o discurso de superioridade racial. Conclui-se que as instituições sociais neoliberais promovem a ideia de acesso equitativo aos recursos e oportunidades. Assim, é essencial discutir o racismo estrutural e promover uma educação antirracista para superar as barreiras impostas pelo preconceito e pela desigualdade.
FINITE ELEMENT SIMULATION ANALYSIS OF CURVILINEAR CONTINUOUS BEAM BRIDGE JACKING AND TRANSLATION CONSTRUCTION

This paper investigates the issue of beam misalignment in curved continuous beam bridges. Taking the D0 to D6 spans of the Gongbin Road viaduct as the basis, the main influencing factors causing misalignment in curved beam bridges are analyzed and the causes of transverse and longitudinal misalignment in curved beam bridges are calculated and analyzed using Midas/Civil finite element simulation software. The results indicate that the main influencing factor causing misalignment in the operation of curved continuous beam bridges is the system temperature, with the displacement caused by it being larger than the cumulative displacement caused by self-weight, construction phase, gradient load, vehicle load, and bearing settlement. During operation, the failure of expansion joints changes the boundary conditions of the beam, preventing the bridge from freely expanding and contracting longitudinally under temperature load. As a result, the transverse displacement increases to 2-3 times the normal working state of the expansion joint, leading to beam misalignment.
Zakat Sebagai Pilar Ekonomi Ummat di Indonesia (Studi Konsep Zakat dalam Kompilasi Hukum Ekonomi Syari'ah)
Authors: Elly Triantini Zusiana
Published: September 2024

Dalam satu dekade terakhir ini, muncul fenomena menarik di kalangan umat Islam di Indonesia terkait dengan zakat. Minat atau ketertarikan umat Islam Indonesia untuk membayar zakat mengalami peningkatan, seiring tumbuhnya lembaga- lembaga pegelola zakat, baik "negeri" maupun "swasta". Hal ini juga didorong oleh penggunaan media, baik cetak meupun elektronik yang dikemas secara kreatif sebagai sebuah strategi untuk mengefektifkan pengaruh kesadaran ber-zakat.
Berangkat dari perkembangan kehidupan sosial dan perekonomian akhir-akhir ini terutama masyarakat Islam, maka pembicaraan tentang zakat yang merupakan rukun Islam yang bercorak sosial ekonomi ini semakin menjadi fokus perhatian para ahli dan pihak-pihak yang berkompeten, termasuk dalam hal ini Makamah Agung yang menyusun Kompilasi Hukum Ekonomi Syari'ah dimna salah satu dimensi yang dibahas di dalamnya adalah zakat. Hal itu tidak lain karena zakat, walaupun selalu dibahas di dalam pokok bahasan ibadat, merupakan bagian yang tidak terpisahkan dari shalat, namun sebenarnya juga merupakan bagian dari sistem keuangan, ekonomi, sosial, politik dan moral Islam yang sangat penting dalam upaya membangun ekonomi umat dan menjaga keseimbangan antara yang kaya dan yang miskin, sehingga persoalan ini, selain dibahas dalam konteks ibadat, juga telah menjadi bahasan dalam buku-buku hukum, ekonomi dan bidang keislaman lainnya.
Peran serta negara dan masyarakat tentu tidak dapat dinafikan dalam perkembangan zakat baik secara normatif maupun empiris. Kondisi politik dan ekonomi memiliki andil yang cukup besar pula dalam perubahan tersebut. Munculnya bangrapa peraturan negara tentang zakat, hingga usaha penggabungan antara zakat dan pajak, serta pembentukan badan pengelolaan zakat resmi pemerintah dan sertifikasi terhadap lembaga pengelola zakat non pemerintah serta tersusunnya KHES yang memiliki dasar hukum PERMA no 2 Tahun 2008 merupakan bukti empiris bahwa negara turut berperan penting dalam perkembangan zakat di Indonesia.
