Authors: Kuaban Godlove Suila , Gelenbe Erol , Czachórski Tadeusz , Czekalski Piotr , Tangka Julius Kewir
Published: July 2023

The Internet of Things (IoT) is transforming almost every industry, including agriculture, food processing, health care, oil and gas, environmental protection, transportation and logistics, manufacturing, home automation, and safety. Cost-effective, small-sized batteries are often used to power IoT devices being deployed with limited energy capacity. The limited energy capacity of IoT devices makes them vulnerable to battery depletion attacks designed to exhaust the energy stored in the battery rapidly and eventually shut down the device. In designing and deploying IoT devices, the battery and device specifications should be chosen in such a way as to ensure a long lifetime of the device. This paper proposes diffusion approximation as a mathematical framework for modelling the energy depletion process in IoT batteries. We applied diffusion or Brownian motion processes to model the energy depletion of a battery of an IoT device. We used this model to obtain the probability density function, mean, variance, and probability of the lifetime of an IoT device. Furthermore, we studied the influence of active power consumption, sleep time, and battery capacity on the probability density function, mean, and probability of the lifetime of an IoT device. We modelled ghost energy depletion attacks and their impact on the lifetime of IoT devices. We used numerical examples to study the influence of battery depletion attacks on the distribution of the lifetime of an IoT device. We also introduced an energy threshold after which the device’s battery should be replaced in order to ensure that the battery is not completely drained before it is replaced.

Published: July 2023

Detection of fatigue is extremely important in the development of different kinds of preventive systems (such as driver monitoring or operator monitoring for accident prevention). The presence of fatigue for this task should be determined with physiological and objective behavioral indicators. To develop an effective model of fatigue detection, it is important to record a dataset with people in a state of fatigue as well as in a normal state. We carried out data collection using an eye tracker, a video camera, a stage camera, and a heart rate monitor to record a different kind of signal to analyze them. In our proposed dataset, 10 participants took part in the experiment and recorded data 3 times a day for 8 days. They performed different types of activity (choice reaction time, reading, correction test Landolt rings, playing Tetris), imitating everyday tasks. Our dataset is useful for studying fatigue and finding indicators of its manifestation. We have analyzed datasets that have public access to find the best for this task. Each of them contains data of eye movements and other types of data. We evaluated each of them to determine their suitability for fatigue studies, but none of them fully fit the fatigue detection task. We evaluated the recorded dataset by calculating the correspondences between eye-tracking data and CRT (choice reaction time) that show the presence of fatigue.

Published: July 2023

Fault alarm time lag is one of the difficulties in fault diagnosis of wind turbine generators (WTGs), and the existing methods are insufficient to achieve accurate and rapid fault diagnosis of WTGs, and the operation and maintenance costs of WTGs are too high. To invent a new method for fast and accurate fault diagnosis of WTGs, this study constructs a stacking integration model based on the machine learning algorithms light gradient boosting machine (LightGBM), extreme gradient boosting (XGBoost), and stochastic gradient descent regressor (SGDRegressor) using publicly available datasets from Energias De Portugal (EDP). This model is automatically tuned for hyperparameters during training using Bayesian tuning, and the coefficient of determination (R2) and root mean square error (RMSE) were used to evaluate the model to determine its applicability and accuracy. The fitted residuals of the test set were calculated, the Pauta criterion (3σ) and the temporal sliding window were applied, and a final adaptive threshold method for accurate fault diagnosis and alarming was created. The model validation results show that the adaptive threshold method proposed in this study is better than the fixed threshold for diagnosis, and the alarm times for the GENERATOR fault type, GENERATOR_BEARING fault type, and TRANSFORMER fault type are 1.5 h, 5.8 h, and 3 h earlier, respectively.

Published: July 2023

Despite the substantial progress achieved in the development and integration of augmented reality (AR) in surgical robotic and autonomous systems (RAS), the center of focus in most devices remains on improving end-effector dexterity and precision, as well as improved access to minimally invasive surgeries. This paper aims to provide a systematic review of different types of state-of-the-art surgical robotic platforms while identifying areas for technological improvement. We associate specific control features, such as haptic feedback, sensory stimuli, and human–robot collaboration, with AR technology to perform complex surgical interventions for increased user perception of the augmented world. Current researchers in the field have, for long, faced innumerable issues with low accuracy in tool placement around complex trajectories, pose estimation, and difficulty in depth perception during two-dimensional medical imaging. A number of robots described in this review, such as Novarad and SpineAssist, are analyzed in terms of their hardware features, computer vision systems (such as deep learning algorithms), and the clinical relevance of the literature. We attempt to outline the shortcomings in current optimization algorithms for surgical robots (such as YOLO and LTSM) whilst providing mitigating solutions to internal tool-to-organ collision detection and image reconstruction. The accuracy of results in robot end-effector collisions and reduced occlusion remain promising within the scope of our research, validating the propositions made for the surgical clearance of ever-expanding AR technology in the future.

Published: July 2023

The present study contains an experimental analysis of the vibratory response in a low-cylinder engine motorcycle at varying suspension preloads. Three different speed bumps of varying heights were used to subject the motorcycle to different vibrations. The analysis was carried out in three domains: time, frequency, and time-frequency. A triaxial accelerometer was used to measure the vibrations at the seat of the vehicle. The results indicated that the suspension system became more differentiated as the height of the bumps increased. However, for lower bumps, the action of the three spring preloads studied was quite similar. Quantitatively, only the higher bump showed a significant difference between the set preloads. The spectral distribution revealed that the frequency of interest was below 20 Hz for all the studied cases, which is in the same range of human body natural frequencies. The findings of this research can be utilized to enhance the design of low-cost motorcycles, thereby improving the safety and comfort of their drivers and passengers. This study constitutes a significant step towards developing an affordable system capable of gathering sufficient data to support the creation of evidence-based public health policies and propose new transport industry standards based on field measurements.

Published: July 2023

Water Loss (WL) is a global issue. In Italy, for instance, WL reached 36.2% of the total fresh water conveyed in 2020. The maintenance of a water supply system is a strategic task that requires a huge amount of investment every year. In this work, we focused on the use of Distributed Fiber Optic Sensors (DFOS) based on Stimulated Brillouin Scattering (SBS) technology for monitoring water pipeline networks. We worked on High-Density Polyethylene (HDPE) pipes, today the most widely used for creating water pipelines. By winding and fixing the optic fiber cable on the pipe’s external surface, we verified the ability to detect strain related to pressure anomalies along a pipeline, e.g., those caused by water leakage. We performed two experimental phases. In the first one, we assessed the sensibility of sensor layout on an HDPE pipeline solicited with static pressure. We investigated the viscoelastic rheology of the material by calibrating and validating the parameters of a Burger model, in which Maxwell and Kelvin-Voigt models are connected in series. In the second experimental phase, instead, we focused on the detection of the pressure anomaly produced by leakage in a pipeline circuit set up with running water moved by a pump. The theoretical and experimental studies performed returned overall positive feedback on the use of DFOS for the monitoring of HDPE water pipelines. Future developments will be focused on more detailed studies of this monitoring solution and on the industrial production of “natively smart” HDPE pipes in which DFOS cables are integrated into the pipeline surface during the extrusion process.
Explorative Data Analysis Methods: Application to Laser-Induced Breakdown Spectroscopy Field Data Measured on the Island of Vulcano, Italy

Published: July 2023

One of the strengths of laser-induced breakdown spectroscopy (LIBS) is that a large amount of data can be measured relatively easily in a short time, which makes LIBS interesting in many areas, from geomaterial analysis with portable handheld instruments to applications for the exploration of planetary surfaces. Statistical methods, therefore, play an important role in analyzing the data to detect not only individual compositions but also trends and correlations. In this study, we apply two approaches to explore the LIBS data of geomaterials measured with a handheld device at different locations on the Aeolian island of Vulcano, Italy. First, we use the established method, principal component analysis (PCA), and second we adopt the principle of the interesting features finder (IFF), which was recently proposed for the analysis of LIBS imaging data. With this method it is possible to identify spectra that contain emission lines of minor and trace elements that often remain undetected with variance-based methods, such as PCA. We could not detect any spectra with IFF that were not detected with PCA when applying both methods to our LIBS field data. The reason for this may be the nature of our field data, which are subject to more experimental changes than data measured in laboratory settings, such as LIBS imaging data, for which the IFF was introduced first. In conclusion, however, we found that the two approaches complement each other well, making the exploration of the data more intuitive, straightforward, and efficient.

Authors: Zemla Katarzyna , Sedek Grzegorz , Wróbel Krzysztof , Postepski Filip , Wojcik Grzegorz M.
Published: July 2023

The aim of this study was to investigate the potential impact of guided imagery (GI) on attentional control and cognitive performance and to explore the relationship between guided imagery, stress reduction, alpha brainwave activity, and attentional control using common cognitive performance tests. Executive function was assessed through the use of attentional control tests, including the anti-saccade, Stroop, and Go/No-go tasks. Participants underwent a guided imagery session while their brainwave activity was measured, followed by attentional control tests. The study’s outcomes provide fresh insights into the influence of guided imagery on brain wave activity, particularly in terms of attentional control. The findings suggest that guided imagery has the potential to enhance attentional control by augmenting the alpha power and reducing stress levels. Given the limited existing research on the specific impact of guided imagery on attention control, the study’s findings carry notable significance.
Transmission Line-Planning Method Based on Adaptive Resolution Grid and Improved Dijkstra Algorithm
Authors: Nan Guojun , Liu Zhuo , Du Haibo , Zhu Wenwu , Xu Shuiqing
Published: July 2023

An improved Dijkstra algorithm based on adaptive resolution grid (ARG) is proposed to assist manual transmission line planning, shorten the construction period and achieve lower cost and higher efficiency of line selection. Firstly, the semantic segmentation network is used to change the remote sensing image into a ground object-identification image and the grayscale image of the ground object-identification image is rasterized. The ARG map model is introduced to greatly reduce the number of redundant grids, which can effectively reduce the time required to traverse the grids. Then, the Dijkstra algorithm is combined with the ARG and the neighborhood structure of the grid is a multi-center neighborhood. An improved method of bidirectional search mechanism based on ARG and inflection point-correction is adopted to greatly increase the running speed. The inflection point-correction reduces the number of inflection points and reduces the cost. Finally, according to the results of the search, the lowest-cost transmission line is determined. The experimental results show that this method aids manual planning by providing a route for reference, improving planning efficiency while shortening the duration, and reducing the time spent on algorithm debugging. Compared with the comparison algorithm, this method is faster in running speed and better in cost saving and has a broader application prospect.
Performance Assessment Comparison between Physically Based and Regression Hydrological Modelling: Case Study of the Euphrates–Tigris Basin
Authors: Guzey Goksel Ezgi , Önöz Bihrat
Published: July 2023

This paper presents two hydrological models developed for the Euphrates–Tigris Basin in Turkey. The first model is a linear regression-based model allowing the estimation of streamflow based on available hydroclimatic data (precipitation, temperature, evapotranspiration, etc.) with the use of clustering analysis. The second model consists of an elevation-based semi-distributed hydrological model (HBV model), allowing process-based modelling of the watershed. A set of performance metrics identified the HBV model as the best performance in terms of predicting streamflow (NSE = 0.752), while the RCA4-EU regression model of CORDEX showed the most robust performance. The results show the potential of regression models from a computational and data point of view in being integrated into physically based models wherein a hybrid approach might be beneficial. The comparison of conceptual models with statistical analyses of streamflow shows the potential of regression analysis when the regions are clustered in hydro-meteorologically homogeneous groups. The employment of the conceptual model HBV also provides significantly robust streamflow estimation for the region, which is especially important in estimating the hydropower potential of the region’s near future.
Scalable Electronic Health Record Management System Using a Dual-Channel Blockchain Hyperledger Fabric
Authors: Díaz Álvaro , Kaschel Héctor
Published: July 2023

Communication and information technologies have accelerated the implementation of electronic medical records, but at the same time, have put patient privacy, information security and health data at risk. An alternative to address the problem of security and privacy of medical data is the use of blockchain. Scalability has become one of the biggest challenges facing the development of blockchain-based electronic health records (EHRs). The purpose of this article is to implement and test a scalable blockchain-based EHR management system. For this reason, we present a scalable blockchain-based EHR management architecture. In this paper, we propose an EHR management model based on entities and user roles, adapt, and then implement with Hyperledger Fabric in a two-channel configuration. We develop a prototype in Fabric using a one-and two-channel configuration. We then designed and conducted an experiment to verify the performance of the proposed scheme in terms of scalability improvement. This scalable blockchain-based EHR management solution, such as the Hyperledger Fabric platform, offers a viable alternative to address scalability issues, as well as to protect patient’s privacy and the security of their medical data.

Published: July 2023

This paper examines possible causes, consequences, and potential solutions for addressing vaccine hesitancy in the United States, focusing on the perspectives of academic scientists. By examining the experiences of scientists, who are arguably a critical community in US society, we gain deeper insights into how they understand the complexities of vaccine hesitancy and whether their insights and opinions converge with or diverge from the current literature. We present findings from a national survey of a representative sample of academic scientists from the fields of biology and public health regarding vaccine hesitancy and related topics. Empirical analysis using descriptive, bivariate, and multivariate analyses covers multiple topics, including vaccine controversy, trust in science, causes of vaccine hesitancy, preferred policy and regulatory approaches, risk perceptions, and scientists’ ethics and perceived communication roles. The results highlight a diversity of opinions within the scientific community regarding how to improve science-society communication in regard to vaccines, including the need to be transparent and candid to the public about the risk of vaccines and their research.
Parent–Child Vaccination Concordance and Its Relationship to Child Age, Parent Age and Education, and Perceived Social Norms
Authors: Tu Pikuei , Smith Danielle , Parker Taylor , Pejavara Kartik , Michener J. Lloyd , Lin Cheryl
Published: July 2023

Researchers established that parental vaccination status often predicts that of their children, but a limited number of studies have examined factors influencing dyadic concordance or discordance (i.e., same or different vaccination status or intent for both members). We investigated how child versus parent age as well as parents’ perceptions of their respective friends’ immunization behavior impacted un/vaccinated parents’ decisions regarding vaccinating their child. An online survey obtained the COVID-19 vaccination status and views of 762 parents of 5–17-year-old children. More than three-quarters of all dyads were concordant; 24.1% of vaccinated parents would not vaccinate their child, with greater hesitancy for younger children and among younger or less educated parents. Children of vaccinated parents and of parents who thought most of their child’s friends were vaccinated were 4.7 and 1.9 times, respectively, more likely to be vaccinated; unvaccinated parents were 3.2 times more likely to accept the vaccine for their child if they believed most of their friends would vaccinate their children. Further, parents who reported that most of their friends were vaccinated were 1.9 times more likely to have obtained the vaccine themselves, illustrating the influence of social norms. Regardless of their own vaccination status, parents of unvaccinated children were more likely to be politically conservative. If communities or circles of friends could achieve or convey a vaccinated norm, this might persuade undecided or reluctant parents to vaccinate their children. Future research should examine the effects of community behavior and messages highlighting social norms on pediatric vaccine uptake.

Published: July 2023

Hotel dan resort merupakan sarana dan prasarana akomodasi tempat menginap. Salah satu cara untuk meningkatkan daya tarik hotel dan resort adalah dengan menerapkan konsep rancangan yang mencerminkan unsur budaya setempat, karena merupakan objek wisata yang menarik bagi wisatawan luar negri maupun lokal. Unsur budaya diterapkan dalam bentuk massa bangunan maupun tapak bangunan. Hal ini sejalan dengan peraturan pemerintah daerah untuk tetap menjaga dan memelihara nilai-nilai lokal yang ada dalam kehidupan masyarakat. Selain itu ketentuan yang ditetapkan oleh pemerintah daerah mengenai bangunan dan lingkungannya harus diterapkan untuk menjamin keamanan, dan keselamatan bangunan. Permasalahan yang ditemui saat ini adalah kurangnya penerapan konsep rancangan bangunan yang menerapkan unsur-unsur budaya lokal di kawasan wisata Mandeh. Metode yang digunakan untuk mengumpulkan data mengenai unsur budaya lokal pada bangunan di kawasan Mandeh tersebut adalah metode kualitatif dengan cara observasi. Sedangkan metode perancangan dilakukan dengan penerapan ideologi dan prinsip desain neo vernacular. Dari pengamatan di lapangan, ditemui cukup banyak bangunan yang dirancang tanpa menerapkan unsur budaya lokal. Upaya untuk memelihara nilai-nilai lokal dilakukan dengan menerapkan konsep bangunan hotel bergaya arsitektur neo-vernacular pada gubahan massa bangunan. Hasil tersebut diharapkan dapat menjadi dasar dalam perancangan gubahan massa bangunan yang menerapkan filosofi lokalitas namun tetap sesuai dengan kondisi perkembangan masa kini.

Using Evaluations to Identify and Eliminate a Barrier to Invasive Weed Control
Authors: Edgerton Angelique , Reichenbach Michael
Published: July 2023

Evaluation is an important component of educational programming. An example of how evaluation is used to assess need, identify barriers, and guide program development is presented. Impact evaluations from a yearlong project to teach landowners about invasive weed identification and control indicated one of the barriers to implementing knowledge was a lack of access to invasive species control tools. Knowledge of this barrier enabled community organizers to guide the development of a community herbicide shed (CHS). Evaluations of landowners who used the CHS show that the CHS effectively changed the knowledge, attitudes, and practices of all participants.

Using Dice Games to Teach Hazards, Risk, and Outcomes in HACCP Classes
Authors: Oyarzabal Omar
Published: July 2023

This article describes the incorporation of a dice game (piggy) to teach food safety hazards and risk in an engaging way in HACCP classes. Each player accumulates points by rolling two dice, but loses points in a turn when rolling a 7, or all accumulated points when rolling two consecutive doubles. This game helps explain the difference between a concrete event, a hazard (number 7) and risk of that hazard occurring (the probability of rolling number 7). Two consecutive doubles inflict a more severe loss and can help explain the variability in outcomes of food safety hazards.

A esporotricose é uma micose de difícil tratamento e tem os gatos como um dos principais hospedeiros. Suas manifestações clínicas são caracterizadas, principalmente por lesões de continuidade ulcerativas na pele e subcutâneo, linfocutânea, disseminada, com presença de sinais extracutâneo e sistêmica fatal.  Seu tratamento baseia-se na administração de antifúngicos sistêmicos e tópicos, porém causam danos expressivos ao organismo e ao ambiemte. Com poucas opções de tratamento, a ozonioterapia pode ser indicada para o tratamento de afecções infecciosas para esporotricose, devido a ação fungicida, analgésica e anti-inflamatória. Objetivou-se em descrever o caso clínico de um felino, macho, castrado de 1 ano e 8 meses, que apresentava lesões ulcerativas no membro pélvico esquerdo e coxim plantar, diagnosticado com esporotricose. Uma vez que não havia a regressão das lesões com o tratamento convencional, foi instituído a ozonioterapia pela técnica de insuflação de bag’s. Após 12 sessões, as feridas estavam parcialmente cicatrizadas, manteve-se o tratamento convencional com a adição do uso de óleo de girassol ozonizado até a regressão total das lesões.

As Tecnologias Digitais de Informação e Comunicação (TDIC) demandam novos processos formativos e a redefinição do papel dos professores para o desenvolvimento de suas competências digitais. Nesse quesito, este trabalho se direciona a investigar os conceitos das competências digitais docentes, bem como a existência de políticas públicas para a formação dos professores com o uso das TDIC, a partir de outras literaturas já existentes. Para tanto, a referida pesquisa tem por método uma Revisão Sistemática da Literatura (RSL), proposto por Kitchenham e Charters (2007). Nessa perspectiva, foram analisadas publicações no período entre 2015 a 2021, nos seguintes repositórios: portal de periódicos da CAPES, catálogos de teses e dissertações da CAPES, Google acadêmico e Scientific Electronic Library Online – Scielo, com a respectiva string de busca: “competências digitais” AND “formação de professores” AND “docentes”. Os resultados apontam que os conceitos de competências digitais docentes não se desenvolvem isoladamente e que há uma forte influência dos documentos internacionais nessa base conceitual, principalmente do DigCompEdu. Destarte, verificou-se também que as políticas públicas nacionais ainda necessitam transitar pela real necessidade de desenvolvimento de competências digitais de professores e da reflexão sobre novos paradigmas didático-pedagógicos com o uso das TDIC.

O artigo apresenta parte do estudo que objetivou diagnosticar as condições de acesso, produção, implementação e avaliação de atividades pedagógicas no contexto online de professores de Matemática, Física, Química, Biologia e Ciências atuantes em escolas localizadas no estado do Rio Grande do Sul. O diagnóstico não se restringiu ao período pandêmico, apesar de compreendermos que durante esse período, recursos digitais foram implementados com maior intensidade. Neste artigo focamos na apresentação e análise das informações referentes aos desafios da produção e implementação de materiais didáticos com o uso das tecnologias digitais. A coleta de informações foi realizada através de um formulário virtual, constituído de 27 questões, sendo que participaram da pesquisa 29 professores. A análise dos resultados revelou que o período pandêmico oportunizou o aperfeiçoamento de práticas pedagógicas dos professores a partir e com as tecnologias digitais. Além disso, as respostas sinalizaram que os professores se mostram receptivos à utilização desses recursos no (re)criar desenhos didáticos, mesmo em período pós-pandemia, com vistas à superação da fragmentação e da reprodução linearizada de conhecimentos. Porém, ainda indicam a necessidade de melhorias na infraestrutura tecnológica das escolas e da criação de espaços formativos que alinhem a formação técnica e pedagógica.

A biotecnologia na formação de professores de Biologia: uma revisão sistemática da literatura
Authors: Ribeiro de Lima Jairo , Lima Vasconcelos Francisco Herbert , De Vasconcelos Silva Maria Goretti
Published: July 2023

Na área da Biotecnologia, várias descobertas orientaram avanços para a sociedade por meio do uso do conhecimento científico e tecnológico. Seus bens e serviços fazem parte do cotidiano de toda a população em geral. Não obstante, a introdução de temáticas biotecnológicas nos espaços educacionais perpassa a formação docente. Nessa perspectiva, o presente artigo teve como objetivo investigar o cenário das pesquisas nacionais e internacionais em relação à inserção da Biotecnologia na formação de professores de Biologia. Para tanto, desenvolveu-se uma pesquisa de natureza mista, utilizando os pressupostos da pesquisa bibliográfica do tipo Revisão Sistemática de Literatura (RSL), de cunho secundário, com protocolos de busca bem definidos e questões norteadoras. Os dados foram obtidos por meio das bases de dados Google Acadêmico, Periódicos CAPES, SciELO, Arca, ERIC, ACM, Scopus e ScienceDirect publicados nos últimos dez anos (2012-2022). A análise quantitativa demonstrou que há uma carência de estudos que contemplem a temática, entretanto, há uma tendência de crescimento no número de pesquisas na última década. A análise qualitativa revelou que os estudos são incipientes quanto à abordagem de tópicos biotecnológicos direcionados à formação docente. Portanto, os resultados apontam para a necessidade de investimentos em pesquisas que promovam um debate mais centralizado entre a formação docente e o Ensino de Biotecnologia na Educação Básica.

Authors: Marques de Oliveira Ademilson , Rauh Schmitt Marcelo Augusto
Published: July 2023

Este estudo pertence à área das tecnologias educativas, mais especificamente, se concentra no ensino remoto durante o período da pandemia da Covid-19. Buscou-se compreender como o software Google Classroom pode colaborar para a qualidade do processo de ensino e aprendizagem e impactar no ensino da rede pública de Ensino Superior. Dessa forma, analisou-se como o Google Classroom foi utilizado na Universidade Federal do Espírito Santo para a implementação do ensino remoto em cursos de graduação. Verificou-se, ainda, como se dá o processo de ensino e aprendizagem por meio desse software e se ele é um recurso que influencia positivamente na qualidade da prática docente a fim de sugerir seu uso para outras instituições de ensino enquanto uma ferramenta tecnológica de apoio ao ensino presencial. Este estudo de caso é de abordagem qualitativa e de natureza aplicada. Conclui-se que o uso do Google Classroom foi viável no ensino remoto da UFES e poderá colaborar para a potencialização da qualidade do ensino híbrido na educação superior.

Sujeitos homoafetivos e seus percursos escolares: ações docentes e a escola como fábrica de subjetividades
Authors: Rhoden Debora , Petró Vanessa
Published: July 2023

A escola ao assumir sua função social deve trabalhar em prol da formação integral de cidadãos promovendo a transformação da sociedade, assim como, garantir um processo educativo de qualidade que reconheça a diversidade. O artigo tem por objetivo compreender os percursos escolares de sujeitos homoafetivos considerando a influência da escola na “produção” de subjetividades. Além disso, analisar ações docentes e de gestores por meio da perspectiva dos sujeitos homoafetivos e investigar os marcos de memórias desses sujeitos. A pesquisa, de abordagem qualitativa, foi desenvolvida através de entrevistas narrativas que revelam a urgência de repensarmos o espaço escolar, afinal, além de relações afetivas, há muitas memórias de hostilidade e sofrimento dentro dele. As análises e resultados obtidos reafirmam a ação da heteronormatividade sobre os sujeitos. Os professores que perpassam seus caminhos também deixaram suas marcas. Tais fatores implicam na construção de suas subjetividades uma vez que estão inseridos na escola por longos anos de suas vidas.

O estigma do envelhecimento no cinema: representações e pedagogias do horror em The Amusement Park (1975), de George Romero
Authors: Bitencourt Fortes Lucas , Massola Gisele
Published: July 2023

O presente artigo objetiva identificar e analisar representações e pedagogias no que se refere ao envelhecimento a partir do filme “The Amusement Park” (1975), do diretor norte-americano George Andrew Romero. As ancoragens teóricas pautam-se em abordagens do campo dos Estudos Culturais fazendo uso da metodologia de etnografia em tela, com inspirações na análise cultural e na metodologia visual crítica, se propõe, conjuntamente a seu objetivo principal, pensar o potencial pedagógico que produções cinematográficas possuem, sobretudo as do gênero de horror, e como elas possibilitam a reflexão acerca de problemáticas no tocante ao envelhecimento na atualidade. Compreende-se que, apesar da produção ser oriunda da década de 70, representações e pedagogias produzidas a partir do horror que dela emanam contribuem significativamente para pensar o envelhecimento, seja pensando as dificuldades e problemas vivenciados pelos idosos, sobretudo no tocante às múltiplas formas de violência as quais estão sujeitos, como dilemas e responsabilidades dos mais jovens quando de frente a esta questão.
