Metáforas multimodais sobre a reforma da Previdência Social no Brasil: uma análise semântico-cognitiva no gênero charge

This article aims to describe and analyze multimodal metaphors activated by pictorial representations allied to the linguistic manifestation present in cartoons which deal with the social security reform in Brazil. In order to reach the established objective, our article is based on the Theory of Multimodal Metaphors, according to the studies of Forceville (2009), Forceville and Urios-Aparisi (2009) and Sperandio (2014). We also draw on the studies on the Metaphorical System of Morality, according to Lakoff and Johnson (1999) and Lakoff (2016 [1996]). The corpus consists of six cartoons that were collected in the months of September, October, November and December of 2017 in two specialized sites, namely: Online Charge and Political Humor. Throughout this research, we conclude that the cartoon producers categorize social security reform either as trade/negotiation, or as assault, or as dirt. It was verified that multimodal metaphors corroborate with the criticisms made by the cartoon producers, and have also the semantic-discursive function of reporting/criticizing situations or public people of our daily routine.Este artigo tem como objetivo descrever e analisar as metáforas multimodais acionadas pela representação pictórica aliada às manifestações linguísticas presentes em charges que versam sobra a reforma da previdência social no Brasil. A fim de atingir o objetivo firmado, nosso trabalho está balizado na Teoria das Metáforas Multimodais, conforme os estudos de Forceville (2009), Forceville e Urios-Aparisi (2009) e Sperandio (2014). Lançamos mão também dos estudos sobre o Sistema Metafórico da Moralidade, de acordo com Lakoff e Johnson (1999) e Lakoff (2016 [1996]). O corpus é composto por seis charges que foram coletadas nos meses de setembro, outubro, novembro e dezembro de 2017 em dois sites especializados, a saber: A Charge Online e Humor Político. Através desta pesquisa, concluímos que os produtores de charges categorizam a reforma da previdência social ora como comércio/negociata, ora como assalto e ora como sujeira. Foi constatado que as metáforas multimodais corroboram com as críticas feitas pelos chargistas, e possuem também a função semântico-discursiva de denunciar/criticar situações e pessoas públicas do nosso dia a dia

Development of a low-cost ground segment capable of receiving data from nanosatellites: a partnership between Brazil and Portugal

Two universities joined forces to develop a shared ground segment (Ground Stations and Mission Operation Centers) for satellite signals reception, capable of working together autonomously in a network to receive telemetry data and decode information. The main objective of this cooperation and network is to, firstly, give both universities an infrastructure capable of receiving signals in VHF and UHF. Secondly, and most importantly, it aims to create an exchange of experiences between students from these universities while also contributing to the regional development of each country in nanosatellite data reception technology. The ground segment itself provides mutual data collection on a private server, using two ground stations located in different hemispheres to expand global coverage and minimize revisit time, which also contributes to supplying the nanosatellite telemetries database, which is being built in Portugal. The server architecture allows both universities to schedule future passes of their chosen satellites, recording them in a log file that can be used in future studies, enabling research groups to gain experience in signal processing analysis. The modular system is developed entirely using Commercial Of-The-Shelf (COTS) components and 3D printed parts, including Antennas, Amplifiers, Filters and also SDRs (Software Defined Radio), leaving the door open to new integrations that can expand frequency coverage, or system performance improvements. The design supports a wide variety of missions, operating on amateur radio frequency in VHF (2 m band of 144-146 MHz) and UHF (70 cm band of 430-440 MHz), enabling remote access and remote control of the antennas and their recorded data. All the ground segment architecture, hardware, and software, as well as its operational procedures, are discussed in this paper and can be found in detail on our public repository in GitLab. As of March 21st, it has completed several observations for verification. The results are being processed on a low-cost computer (Raspberry Pi4) connected to an SDR which in turn connects to the antennas. The assembly of this interface intends to give a friendly user experience and, if desirable, an easy expansion of this system. The project developed can be easily replicated in other locations around the world, mainly because of its low price and ease of use

Pré-fragilidade e fragilidade de idosos residentes em município com baixo Índice de Desenvolvimento Humano

OBJECTIVE: to identify the prevalence of the factors associated with pre-frailty and frailty of elderly residents in a municipality with a low Human Development Index METHOD: Cross-sectional study with a populational and household framework conducted with 316 elderly people. Frailty was determined from the presence of three or more of the following factors: (i) self-reported unintentional weight loss; (ii) lack of strength and energy; (iii) weakness; (iv) slowness; (v) low level of physical activity. The association between frailty and socio-demographic, behavioral and health factors was measured using the multinomial logistic regression technique. RESULTS: The prevalence of pre-frailty and frailty was 58.7% and 23.8%, respectively. The adjusted regression model showed that the state of pre-frailty was associated with gender, age group and BMI, and frailty was associated with gender, age group, hospitalization, functional capacity, and self-perceived health. CONCLUSION: The evidence presented in this study demonstrates more variables associated with the frailty condition, reinforcing the concept of a multifactorial clinical syndrome that may result in the loss of functionality.OBJETIVO: identificar la prevalencia y los factores asociados a la prefragilidad y fragilidad de ancianos residentes en un municipio con bajo Índice de Desarrollo Humano (IDH=0,635).

UMA EXPERIÊNCIA EDUCATIVA DE ROBÓTICA EM BAIRROS DE VULNERABILIDADE SOCIAL DE VITÓRIA DA CONQUISTA – BAHIA1

O presente artigo procura descrever a primeira experiência do curso de robótica educacional, planejada para ser desenvolvida com algumas crianças e adolescentes residentes nos bairros das Pedrinhas e do Alto Maron – Vitória da Conquista – BA. O curso é uma ação do projeto de extensão da UESB Alfabetização científica: Uma Perspectiva de Reconstrução Social para a Diversidade Étnicorracial. Esse projeto se propõe tanto a contribuir para a formação de professores na diversidade étnicorracial e étnico-cultural presente nas salas de aulas, quanto possibilitar uma alfabetização científica inclusiva ao se dirigir às crianças e adolescentes pertencentes a escolas localizadas nos bairros de vulnerabilidade social. Nessa perspectiva, procuramos fazer a inserção da física e da robótica nas séries iniciais do ensino fundamental, em um processo de aprendizagem que prima pela construção do conhecimento em concomitância com as (re)construções de identidade e auto-estima. A estratégia metodológica para tal objetivo é fazer uso da robótica educacional e da narrativa poética da ciência

Bichectomy procedure: a discussion on the ethical and legal aspects in odontology

INTRODUCTION: Bichectomy consists of removing part of a fat structure in the region of the cheeks, and it recently gained popularity in the field of odontology, which began to widely perform the procedure, with predominantly aesthetic demands and, with that, doubts and uncertainties arose with respect to its ethical and legal aspects. OBJECTIVE: The objective of this work was to seek national laws, as well as normative and resolutions issued by professional councils, aiming to address such controversies, enlightening professionals to the legitimacy of the procedure. RESULTS: Since 1978, the Federal Councils of Medicine and Dentistry have issued resolutions to determine thresholds for professional performance, which particularly focused on Oral and Maxillofacial Surgery and Traumatology because it is the closest clinical dental specialty of medical practice. Over time, these Councils have been updating these resolutions, considering the technical and scientific advances of the area, but all the resolutions analyzed were unanimous in affirming that the accomplishment of bichectomy with a strictly aesthetic purpose is a medical attribution. CONCLUSION: Subsequently, based on the documents currently in force, it is verified that the dental surgeon who is willing to perform bichectomy surgery for aesthetic purposes will be incur administrative infractions and, consequently, such interpretations can be seen in other legal areas (civil and criminal)

Accuracy of computer-aided image analysis in the diagnosis of odontogenic cysts:a systematic review

This study aimed to search for scientific evidence concerning the accuracy of computer-assisted analysis for diagnosing odontogenic cysts. A systematic review was conducted according to the PRISMA statements and considering eleven databases, including the grey literature. Protocol was registered in PROSPERO (CRD 42020189349). The PECO strategy was used to define the eligibility criteria and only studies involving diagnostic accuracy were included. Their risk of bias was investigated using the Joanna Briggs Institute Critical Appraisal tool. Out of 437 identified citations, five papers, published between 2006 and 2019, fulfilled the criteria and were included in this systematic review. A total of 5,264 images from 508 lesions, classified as radicular cyst, odontogenic keratocyst, lateral periodontal cyst, glandular odontogenic cyst, or dentigerous cyst, were analyzed. All selected articles scored low risk of bias. In three studies, the best performances were achieved when the two subtypes of odontogenic keratocysts (solitary or syndromic) were pooled together, the case-wise analysis showing a success rate of 100% for odontogenic keratocysts and radicular cysts, in one of them. In two studies, the dentigerous cyst was associated with the majority of misclassifications, and its omission from the dataset improved significantly the classification rates. The overall evaluation showed all studies presented high accuracy rates of computer-aided systems in classifying odontogenic cysts in digital images of histological tissue sections. However, due to the heterogeneity of the studies, a meta-analysis evaluating the outcomes of interest was not performed and a pragmatic recommendation about their use is not possible
