Creators and spectators facing online information disorder. Effects of digital content production on information skills
Authors: Taddeo Gabriela , de-Frutos-Torres Belinda , Alvarado María-Cruz
Published: May 2022

Misinformation on social media is a major problem facing our society. The experience deriving from use does not guarantee success in identifying false information. This study seeks to determine whether an active role in social media impacts on informational skills. For this purpose, we designed a survey that was administered to 756 young people between 16 and 26 years of age from different educational levels. The results show a profile of creative users who participate in generating their own content and sharing their recommendations openly, as opposed to another profile, the “spectators”, focused on entertainment and interaction. The creator profile is the variable that most contributes to reporting fake news on social media. When contrasting information, educational level is the most relevant aspect, although academic results and creator users also represent a significant contribution. Greater trust in the sources found on social media identifies the active profile, while distrust is associated with the spectators. We recommend that media education puts in place actions intended to recuperate trust in social media, so that they can be utilized critically, encouraging active, not reactive use.

La desinformación en las redes sociales es un problema al que se enfrenta nuestra sociedad. La experiencia de uso no garantiza el éxito para identificar la información falsa. El estudio pretende determinar si un rol activo en los medios sociales influye en las competencias informacionales. Para ello se diseñó una encuesta que se aplicó a 756 jóvenes entre 16 y 26 años de diversos niveles educativos. Los resultados muestran un perfil de usuarios «creadores» que participan en la generación de contenidos propios y en compartir sus recomendaciones abiertamente, frente a otro, los «espectadores», centrados en el entretenimiento y la interacción. El perfil creador es la variable que más contribuye a denunciar noticias falsas en las redes sociales. A la hora de contrastar la información, el nivel educativo es el aspecto más relevante, aunque los resultados académicos y los usuarios creadores también suponen una aportación significativa. Una mayor confianza en las fuentes presentes en las redes sociales distingue al perfil activo, mientras que la desconfianza está asociada con los espectadores. Desde la educación mediática se recomienda emprender acciones destinadas a recuperar la confianza en los medios sociales para que puedan ser utilizados de modo crítico, favoreciendo un uso activo y no reactivo de los mismos.
Unraveling disinformation: Notions and discourses from the Spanish population
Authors: Valera-Ordaz Lidia , Requena-i-Mora Marina , Calvo Dafne , López-García Guillermo
Published: May 2022

Disinformation has become a core concept in communications research, related to media, technological and political phenomena that complexify its definition and diagnosis. Although its approach has been mainly quantitative, focus groups have also been used to understand the perception of the audience of this particular issue. This research is part of this second group of studies, and attempts to investigate the notions and discourses on disinformation in the case of Spain. For this purpose, seven discussion groups were conducted, with a structural sample constructed according to employment situation, ideology and age. The results show a perception of the communicative ecosystem structured in two chronological poles, which contrasts a past of reduced information supply – associated with traditional media – with a current informational environment where there is more media diversity, but also less trust in them. The groups point to the overabundance of information and associated disinformation with decontextualisation, low-quality journalism and the economic and political interests of different actors. Discourses outline a scenario of decline in journalism and the public sphere, which is perceived as polarised and emotional. Disinformation is therefore perceived as a multidimensional phenomenon that is associated with issues of major democratic transcendence rather than merely sending hoaxes through the Internet.

La desinformación se ha convertido en un concepto central en las investigaciones en comunicación, relacionado con diversos fenómenos mediáticos, tecnológicos y políticos que complejizan su definición y diagnóstico. Si bien su abordaje ha sido eminentemente cuantitativo, los grupos de discusión han sido también empleados para conocer la percepción de la audiencia sobre este fenómeno. Esta investigación se sitúa en esta estela, para tratar de indagar en las nociones y discursos que existen sobre la desinformación en el caso español. Para ello, se realizan siete grupos de discusión, con una muestra estructural construida según la situación laboral, la ideología y la edad. Los resultados muestran una percepción del ecosistema comunicativo estructurada en dos polos cronológicos, que contrapone un pasado de menor oferta informativa, asociado con los medios de comunicación tradicionales, a un entorno informacional actual donde existe más diversidad mediática, pero también menos confianza en los medios. Los grupos señalan la sobreabundancia de información, y vinculan la desinformación con la descontextualización, el periodismo de baja calidad y los intereses económicos y políticos de diversos actores. Los discursos delinean un panorama de declive del periodismo y de la esfera pública, que se percibe como polarizada y emocional. La desinformación se percibe, por lo tanto, como un fenómeno multidimensional que se asocia a cuestiones de mayor trascendencia democrática que el envío de bulos a través de Internet.

Le triomphe du rire sur la philosophie
Authors: Devillairs Laurence
Published: May 2022

Depuis quatre cents ans, Molière fait rire. De qui rit-on ? Des dévots, des avares, des hommes, des femmes, des nobles, des bourgeois, de tout ce que l’homme compte de ridicule, de vaniteux et de lâche, de tout ce qui nous fait courir et désirer sans relâche. Molière ne nie pas le tragique de nos existences, mais prend le parti d’en rire. La lucidité, chez lui, est joyeuse. C’est une philosophie que délivre le comique, plus puissante, plus vraie que celle des philosophes des universités et des penseurs de salons.
Rencontres, retrouvailles, coup de foudre et nostalgie
Authors: Woscoboinik-Scheimberg Nora , Golse Bernard
Published: May 2022

Après avoir évoqué les phénomènes de la rencontre, du coup de foudre et des retrouvailles, les auteurs proposent alors de considérer la rencontre sous l’angle d’un surgissement d’une représentation du lien à l’objet. Le concept de représentation d’objet mérite en effet aujourd’hui d’être décondensé en représentation de la place de l’objet, en représentation des liens à l’objet et en représentation enfin de l’objet en tant que tel, niveaux représentationnels qui s’instaurent sans doute successivement au cours du développement précoce. Après quoi, c’est la place du temps et du deuil au sein des rencontres et des retrouvailles qui se trouve abordé avant que soit envisagé le concept « d’Amour fou » d’André Breton à la lumière du concept « d’objet décevant » étudié par René Roussillon.
Consommation Socialement Responsable et perception du prix du produit national au Cameroun : une analyse par les modérateurs psychologiques du consommateur
Authors: Djofack Sidonie , Sogbossi Bocco Bertrand
Published: May 2022

Le présent article met en évidence la relation entre la Consommation Socialement Responsable (CSR) et la perception du prix du produit national. L’effet des variables modératrices psychologiques d’importance telles que les connaissances, l’implication, l’efficacité perçue du consommateur, a également été mis en évidence. Au moyen des équations structurelles, l’enquête portant sur 300 consommateurs révèle que la perception du prix du produit national influence positivement et significativement la CSR. L’effet des modérateurs est avéré sur la relation étudiée. Des implications marketing sur les plans stratégique et opérationnel ont été suggérées.
La domination touristique
Authors: Wilson Tamar Diana , Ypeij Annelou , Gat Amandine
Published: May 2022

La triple quête d’une authenticité ethnique imaginaire, de rapports de genre différenciés et d’un exotisme érotisé opère comme l’un des principaux moteurs de la hausse du tourisme occidental en Amérique latine et dans les Caraïbes. Y aborder le phénomène touristique comme un rapport social revient à mettre au jour les différentes formes de domination – entre opérateurs, visiteurs et visités – qui le constituent et le renouvellent.
La domination touristique
Authors: Hillali Mimoun
Published: May 2022

Considéré comme « moteur de développement » durant la Guerre froide, le tourisme est présenté aujourd’hui comme outil d’appoint ou de lutte contre la pauvreté. Or, aussi « doux » annonce-t-il désormais être – durable, éthique, responsable, etc. –, force est de reconnaître qu’en dépit des recommandations de l’OMT et de pays comme le Maroc, il a surtout perpétué un rapport néocolonial entre les pays émetteurs de touristes et l’Afrique.
La domination touristique

Published: May 2022

Caractérisée par une biodiversité exceptionnelle menacée par de nombreuses actions anthropiques, l’île de Madagascar a aussi fait l’objet ces vingt-cinq dernières années de plusieurs entreprises conjointes de préservation de l’environnement et de mise sur pied de projets écotouristiques. Or, ces dynamiques participent plus à la pénétration d’un modèle néolibéral de développement exportateur qu’à la construction d’alternatives durables.

Mus par des objectifs de rentabilité financière immédiate, les opérateurs, publics et privés, du développement touristique de Saly sur la « Petite Côte » sénégalaise – première station balnéaire d’Afrique subsaharienne – ont sous-estimé les dégâts environnementaux, culturels et économiques occasionnés. Le littoral, écosystème fragile, et les populations locales, agriculteurs et pêcheurs, en ont fait les frais. Appel à une redéfinition du modèle.
Les nouveaux territoires de l’agrobusiness
Authors: Alonso-Fradejas Alberto , Jeminet Isabelle
Published: May 2022

Le populisme autoritaire n’est pas l’apanage des gouvernements réactionnaires. C’est aussi l’outil de domination des complexes agro-industriels qui se livrent à la monoculture de la canne à sucre et du palmier à huile. L’expérience du Guatemala montre comment l’oligarchie blanche propriétaire des plantations s’y prend pour asseoir, légitimer et pérenniser son pouvoir et ses profits, au détriment des populations locales et de l’environnement.
La pure perte. Le discours philosophique à l’épreuve de la mort
Authors: Gutkin-Guinfolleau Pierre-Alban
Published: May 2022

Il s’agit dans ce bref essai de s’interroger sur ce que le discours philosophique peut exprimer de la mort. Tout semble, d’un point de vue philosophique, rendre impossible la restitution fidèle de l’expérience de la mort. Et pourtant le discours philosophique ne cesse de s’emparer de cet objet. Au prix de plusieurs déplacements. L’objectif que nous poursuivons est alors – sous la forme d’un cheminement dont la méthode d’investigation consiste à suivre les déterminations majeures que l’expérience de la mort fait subir au discours philosophique – de penser une philosophie de la mort comme une philosophie de la perte et même de la pure perte. Si la philosophie est bien souvent séduite par les conceptualités (socio-historiques et esthétiques essentiellement) qui l’avoisinent, il nous reviendra d’interroger ces usages dans un premier moment, avant de montrer en quoi les philosophies et plus généralement les réflexions sur la perte (comme la psychanalyse freudienne et l’économie générale de Georges Bataille) nient ou neutralisent la perte dans une approche systématique.
Morts sans monde
Authors: Wiel Véronique
Published: May 2022

Réfléchir à la « mort dérobée » en ces temps de pandémie nous impose de scruter plus largement ce qu’il en est du « traitement » moderne de la mort et d’y reconnaître tous les signes d’une « dé-mondanisation », d’une néantisation qui laisse les morts sans monde. Une telle destitution demande à être éclairée par une autre : celle de la vie, ou plutôt celle de « l’exception humaine » en ce domaine. Ce n’est pas seulement l’incapacité ou le refus de la saisir autrement qu’à son niveau biologique qui en cause ; ce sont aussi un langage, des pratiques nouvelles relevant d’un système de délégations ou de substitutions généralisé qui au total réifient les vivants – et les morts.
S’ouvrir à l’« autre croyant » : conditions et fruits d’une exigence théologique
Authors: Vivier-Muresan Anne-Sophie
Published: May 2022

L’ouverture sur l’altérité religieuse constitue un rendez-vous incontournable de toute élaboration théologique. Nous en montrons ici les modalités en prenant appui sur l’expérience du dialogue interreligieux et du dialogue œcuménique. Après une brève introduction biblique mettant en perspective le rôle structurant de l’altérité dans le projet de Dieu, nous commençons par souligner les moyens à prendre pour échapper à la tentation bien réelle et souvent inconsciente d’instrumentaliser l’altérité rencontrée. Dans un troisième temps, nous présentons les fruits de cette ouverture, en les rassemblant essentiellement sous les termes d’une appréhension plus adéquate du réel, nous menant à une théologie elle-même plus ajustée. Pour ce faire, nous proposons de prendre pour posture de référence la démarche de la « théologie comparative ».
Le projet démocratique
Authors: Frega Roberto
Published: May 2022

Envisager la démocratie comme forme de société plutôt que comme régime politique. Comprendre l’ontologie sociale complexe, faite d’habitudes, schèmes d’interaction, et formes d’organisation qui lui sont propres et qui, seules, donnent tout son sens à la démocratie en tant que régime politique. Telle est la perspective que déploie ce livre. En s’appuyant sur la tradition philosophique du pragmatisme américain, intégrée à la théorie critique et le tocquevilleanisme, il développe une théorie sociale de la démocratie. Il défend l’idée que la démocratie doit être entendue comme un concept qui vise à décrire un état désirable des interactions sociales parmi les individus, en tant que citoyens, mais aussi en tant que membres d’une société qui participent à la vie sociale dans toutes ses institutions: sur leur lieu de travail, dans leur famille, au sein de l’espace public. Il tâche ainsi de dégager les conditions normatives qui favoriseront la démocratisation des marchés, des entreprises, des associations, des églises, des bureaucraties et d’autres institutions sociales. Ce faisant, ce livre nous aide à mieux comprendre la signification, la portée et l’étendue du projet démocratique. Ce projet, ancré dans la vision émancipatrice qui caractérise le monde moderne, se propose d’instaurer une société fondée sur le principe de coopération entre individus libres et égaux. L’idée de démocratie, dès lors, n’acquiert sa signification politique qu’en lien avec cette vision primordiale d’une forme de société qui n’a pas d’équivalent dans toute l’histoire humaine.
Kate Winslet dans Mildred Pierce de Todd Haynes (HBO, 2011) : enjeux d’un passage du grand au petit écran
Authors: Bintein Céline
Published: May 2022

Star de renommée mondiale depuis Titanic (James Cameron, 1996), privilégiant plutôt par la suite des films d’auteur indépendants comme Holy Smoke de Jane Campion (1999), Kate Winslet effectue un nouveau tournant dans sa carrière en interprétant l’héroïne de Mildred Pierce, mini-série réalisée par Todd Haynes pour la chaîne câblée HBO en 2011. Notre article s’attache à éclairer les enjeux esthétiques et culturels qui entourent ce passage de la star du cinéma à la télévision. Il tente notamment de montrer en quoi la persona de l’actrice nourrit la caractérisation du personnage, mais aussi en quoi ce dernier enrichit cette image en retour, et reflète le rapport conflictuel de Winslet avec la célébrité et le statut de star.
La série Fargo ou le ré-ensauvagement du monde. Une économie politique de la prédation
Authors: Flandrin Laure
Published: May 2022

Cet article propose d’examiner l’intelligence du social propre aux trois premières saisons de la série télévisuelle américaine Fargo, inspirée du film des frères Coen sorti en 1996, et diffusée sur la chaîne FX de 2014 à 2017. Ces trois saisons relèvent d’une structuration schématique commune en dépit du format anthologique de la série supposé garantir leur indépendance narrative. Dans chacune de ces saisons, une grande entreprise mafieuse s’avise en effet de réaliser une opération d’expansion aux dépends d’une unité familiale de production. La révolution reaganienne des années 1980 a libéré les désirs d’appropriation sous la forme brute de la prédation et les enjeux de sécurisation du capital sont devenus vitaux chez les entrepreneurs ciblés. Ces récurrences analogiques d’une saison à l’autre témoignent d’un minutieux travail d’exploration sérielle des grandes mythologies américaines, et en particulier du darwinisme social, qui se représente l’économie comme un biotope structuré par des réseaux trophiques et l’homo œconomicus comme un animal. À cet entrecroisement permanent des registres de l’économie, de la biologie et de la guerre, la série oppose classiquement un ressourcement moral du capitalisme américain dans son éthique protestante originelle, mais propose aussi une critique politique autrement plus radicale de l’ultra-libéralisme économique.
Effects of IS Quality on Firm Performance from the Perspective of a Business Executive: The Role of Business Strategy
Authors: Feki Mondher
Published: May 2022

Given the lack of knowledge on IS success evaluation at the organizational level, the purpose of this study is to integrate the resource-based view, process-oriented approach, IS success models into an integrated model to examine the relationship between the IS quality and its performance impacts. This study also examines the moderating effect of the firm’s business strategy on this relationship. The model is tested on a sample of 102 Tunisian firms using the structural equation modeling method. The results show that business-process performance and individual performance played a role of partial mediation in the relationship between IS quality and organizational performance. The results also indicate that the mediation process between IS quality and organizational performance via the business-process performance differs depending on the business strategy. This article is one of a few early efforts that address the role of business strategy in explaining the performance impacts of IS quality.
A Financial Deep Learning Framework
Authors: Li Zhenjun , Liao Yinping , Hu Bo , Ni Liangyu , Lu Yunting
Published: May 2022

Prediction of stock price movement is regarded as a challenging task of financial time series prediction. Due to the complexity and massive financial market data, the research of deep learning approaches for predicting the future price is very difficult. This study attempted to develop a novel framework, named 13f-LSTM, where the AutoRegressive Integrated Moving Average (ARIMA), for the first time, as one of the technical features, Fourier transforms for trend analysis and Long-Short Term Memory (LSTM), including its variants, to forecast the future’s closing prices. Thirteen historical and technical features of stock were selected as inputs of the proposed 13f-LSTM model. Three typical stock market indices in the real world and their corresponding closing prices in 30 trading days are chosen to examine the performance and predictive accuracy of it. The experimental results show that the 13f-LSTM model outperforms other proposed models in both profitability performance and predictive accuracy.

Authors: Tian Jingbai , Yin Jianghao , Mo Ziqian , Luo Zhong
Published: May 2022

Due to the outbreak of the COVID-19, online diagnosis and treatment services have developed rapidly, but it is not easy for patients to choose the appropriate healthcare service in the face of massive amounts of information. This article proposes a multi-dimensional context-aware healthcare service recommendation method, which consists of a healthcare service matching model and a healthcare service ranking model. The former first collects objective knowledge related to doctors and diseases to build a knowledge graph, then matches a group of healthcare services for patients according to the patient’s input; The latter selects 5 indicators from the doctor’s academic level, geographical location, public influence, reputation, etc. to build a TOPSIS model based on the entropy weight method to recommend the most appropriate healthcare services for patients. Finally, taking the patient in Shiyan as an example, the whole process of the method is demonstrated, and the feasibility of the method is verified.
A Temporal JSON Data Model and Its Query Languages
Authors: Ma Ruizhe , Hu Zhangbing , Yan Li
Published: May 2022

As a ubiquitous form of data in the natural world, time has been widely used in many domains such as the military, finance, medical treatment, and environment. Temporal data models that are used to model the dynamic development process of data are constantly proposed, such as temporal database and temporal XML. With the rapid development and popularization of the Web, the requirement of dealing with diverse data efficiently is becoming more important. As a new generation of data exchange language, JSON (JavaScript Object Notation) has been widely used because it is lightweight, has fast parsing, and has high transmission efficiency. In this paper, we propose a novel temporal JSON data model. Based on the proposed temporal JSON data model, we further propose two temporal JSON query languages, t-JSONPath, and t-JSONiq, which are the temporal extensions to JSONPath and JSONiq, respectively. With the proposed temporal JSON data model, we demonstrate our temporal JSON query languages with typical temporal query examples and evaluate their query response times.
Impact of Interactivity on Bookkeeping Application Adoption Intention in the New Normal
Authors: Kumari Pooja
Published: May 2022

The study aims to examine the effects of interactivity on users’ adoption intention via perceived consumption values in the bookkeeping application context after post-pandemic. The study also investigates the moderating effect of users’ involvement on the association between interactivity and perceived values. Data were collected using online survey from 276 SMEs in India. The results indicated that application interactivity enhances users’ perceived consumption values (functional, emotional, social, conditional, and epistemic), in turn adoption intention. Moreover, users’ involvement positively moderates that association between application interactivity and consumption values. The findings of the study suggest bookkeeping application service providers that which specific interactivity features they should emphasize for enhancing users’ adoption intention. The study enriches interactivity, consumption values, and users’ behavioural intention literature.
Fear of Coronavirus on Continuance Intention to Use Food Delivery Apps
Authors: Raman Prashant
Published: May 2022

The objective of this research is to explore the determinants impacting the Indian consumers' continuance intention (CI) to use food delivery apps (FDA) during the COVID-19 pandemic. The study develops a conceptual framework which integrates technology acceptance model (TAM) and expectation confirmation model (ECM), with fear of coronavirus (FOC) and health anxiety (HA). The survey responses of 598 FDA users during the COVID-19 pandemic period in India were examined using PLS-SEM approach. The findings reveal that FOC is the most significant determinant, and HA, satisfaction (SAT), perceived usefulness (PU), perceived ease of use (PEOU), and confirmation (CON) have significant impact (directly/indirectly) on users' CI to use FDAs at the time of coronavirus pandemic. The new normal, which includes social distancing, self-protection, etc., has created new buying habits. The policymakers, start-ups, etc. can gain considerable insights from this research.
Blockchain Technology in the Fashion Industry
Authors: Singh Harjit , Jain Geetika , Kumar Nishant , Hashimy Loha , Shrivastava Archana
Published: May 2022

The concept of fashion has been coupled with technology, where technology has become the protagonist. The transparency between an organization and a customer works as a catalyst, and the customer has taken a more mainstream role. With blockchain technology, companies can reconnect with customers and customers can track the journey of a product from its raw materials to the finished goods. The primary focus of the study is on services and data collected from the following sectors, namely fashion, apparel, and online platforms. The author's main goals are (1) to illustrate an overview of how big data is transforming the service industry, especially the fashion and design sector, and (2) to present various mechanisms adopted in the service industry. The study aims to investigate a model that fits through EXT-TAM and uses additional attributes of blockchain technology with a special reference to fashion apparel. The findings of this study depict a model, where PEOU, PU, and attitude are the major constructs and present a win-win scenario for both the customer and the organization.
Energy Constraint in China at the Expense of Profitability?
Authors: Jia Lijun , Hao Yunjie , Hu Wuyang
Published: May 2022

Although energy constraints, green technology innovation increment, and corporate profitability are issues of central importance to enterprise management and the environment, many aspects of these elements have been neglected in the present work. Using data from listed manufacturing firms in China, this study presents two major findings. First, the authors identify a u-shaped relationship between city-specific energy constraints and business profitability. Second, they find green technology innovation can significantly drive profitability in different types of industries. In addition, the profitability of certain enterprises, such as those that are smaller and younger can be more drastically affected by energy constraints. To develop a green innovation-driven strategy to allow manufacturing enterprises to achieve greater profitability and promote ecological improvements, they recommend energy policies be more individualized to guide “energy-constraint sensitive” enterprises to success.
FUNGOS ENDOFÍTICOS DIAPORTHE: UMA FONTE PROMISSORA DE METABÓLITOS PARA A ÁREA DA SAÚDE
Authors: Dos Santos de Oliveira João Arthur , Gonçalves Nogueira Daniel
Published: May 2022

Diaporthe (Diaporthaceae) é um gênero de fungos que já foram isolados como endófitos em diferentes plantas. Mais de 1.100 espécies de Diaporthe foram descritas até então e estes fungos são capazes de produzir uma gama de metabólitos secundários bioativos com propriedades antimicrobianas, antitumorais, tripanocidas, entre outras. Considerando a grande frequência de isolamento deste gênero de fungos por eles serem amplamente distribuídos e adaptados a diferentes condições ambientais e a variedade de metabólitos produzidos por eles, aqui, realizamos uma revisão da literatura acerca dos metabólitos secundários produzidos por fungos endofíticos do gênero Diaporthe sp. com propriedades medico-farmacêutica. Diaporthein, Phomosines, Ortosporina, Emodin, Mycoepoxydiene, β-glucanas, Dicerandrol, Benzeneetanol e Cordisinina são alguns exemplos de metabólitos bioativos produzidos por este gênero de fungos, especialmente por D. phaseolorum, D. arecae e D. schini. Estes metabólitos secundários podem atuar contra patógenos de importância clínica como Mycobacterium tuberculosis, Staphylococcus aureus, Escherichia coli e Tripanossoma cruzi, atenuar a proliferação de células tumorais (KB, Raji, MCF-7 e HepG2-C3A) e reduzir os radicais oxidativos. Conhecer e elucidar os mecanismos de ação dos compostos produzidos não somente por este gênero de fungos endofíticos, mas também de outros microrganismos endofíticos, possibilita o surgimento de novos fármacos e sua produção em grande escala

Authors: Moreira Daiani Rodrigues , Ferreira Helaine Patricia , Francieli Aparecida Moreira
Published: May 2022

O presente artigo aborda sobre o uso de recursos lúdicos nas disciplinas escolares e tem por objetivo entender a utilização da gamificação em escolas públicas como instrumento didático-pedagógico, investigando se esse processo pode facilitar e/ou melhorar a aprendizagem. O estudo justifica-se devido as metodologias empregadas pelos professores no período da pandemia da COVID-19, visto que estes tiveram que repensar e adaptar suas práticas pedagógicas de forma rápida para atender a demanda do ensino remoto. Para isso, foi realizada pesquisa bibliográfica para compreender a temática da gamificação e pesquisa de campo, aplicando um questionário para 182 educadores de quatro escolas públicas do Paraná. Após aplicação, 66 professores responderam o questionário. Verificou-se que 39,4% apresenta faixa etária de 50 a 59 anos, 56,1% dos profissionais trabalham no Ensino Fundamental e no Ensino Médio e 40,9% dos participantes atuam acima de 16 anos na docência. Além disso, foi identificado que 87,9% dos profissionais utilizam recursos didáticos diferenciados e que 63,6% conhecem ou já ouviram falar sobre a gamificação. Todavia, 53% dos professores não utilizam games, porém, 98,5% reconhecem sua importância na aprendizagem do aluno, no qual, 22,7% dos profissionais indicaram uma contribuição de grau 10 (maior escala). Sobre a capacitação para emprego de games, 74,2% responderam que não tiveram essa complementação e apontaram que 42,4% das escolas não apresenta espaço adequado para essas práticas. Assim, conclui-se que a gamificação é uma ferramenta importante para o ensino e que precisa ser conhecida e explorada nas instituições escolares buscando uma aprendizagem significativa.

Authors: Luis Gustavo de Sousa Perugini
Published: May 2022

Mikania glomerata Spreng. (Asteraceae) é uma planta medicinal de hábito trepador, conhecida popularmente como “guaco”. Apresenta inflorescências formadas por um grande número de pequenos capítulos com flores branco-esverdeadas, as quais disponibilizam néctar e grãos de pólen como recursos alimentares aos insetos visitantes florais. Buscando estabelecer a importância dos jardins urbanos para a manutenção da entomofauna na cidade de Maringá, localizada na região Norte do Paraná, objetivou-se reconhecer a diversidade de insetos que visitam as inflorescências do guaco. As coletas de insetos visitantes foram realizadas no jardim dos polinizadores do Museu Dinâmico Interdisciplinar, localizado no Campus Sede da Universidade Estadual de Maringá (MUDI/UEM), localizado em área urbana e onde são cultivadas dezenas de outras espécies vegetais relacionadas com a entomofilia. Na primeira quinzena do mês de outubro de 2019 foram dispensadas nove horas de esforço amostral, das 7h30min às 18h, nas grandes parreiras de guaco do MUDI, onde foram realizadas coletas ativas de insetos que interagiam com suas inflorescências. A diversidade de insetos visitantes das inflorescências do guaco esteve representada 31 espécies, distribuídas em cinco ordens, destacando-se Hymenoptera como a mais rica (13 espécies ou 41,94%) e nela Apis mellifera scutellata, como a espécie mais comum no período amostral. Hemiptera esteve representada por sete espécies, Diptera por cinco, Coleoptera por quatro e Lepidoptera por duas. Mikania glomerata mostrou importante interação com a comunidade de insetos do Campus Sede da UEM e portanto, deve ser incluída nos programas de conservação de insetos urbanos.

The questionnaire was divided into four parts: Demographic characteristics, knowledge, and attitude toward TB, and practices toward the prevention and control of TB.

Results:

The findings showed that most students had a moderate level of knowledge (obtained 47–92 out of the total 138 marks) and practice (obtained 29–57 out of the total 86 marks) and a good attitude related to TB (obtained 20–28 out of the total 28 marks). There were no significant differences in the level of KAP scores between the different genders, ages and years of study among the participants. However, a significant result was found between the KAP level of the various faculties (P < 0.001, <0.001 and 0.027, respectively), with the students from the Faculty of Medicine having the highest KAP level compared to others.

Conclusion:

This study also portrayed that higher knowledge was associated with a higher attitude and practice towards TB (P < 0.001 and 0.045, respectively). Based on the findings, the study proposes more health education programs to promote the awareness on early prevention of TB to achieve an improved level of KAP in controlling and preventing TB infection.
Bilateral Massive Complex Composite Odontoma of the Mandible: A Rare Case Report
Authors: Singh Priyankar , Iqbal Jawed , Imam Zeenat S. , Biswas Krishna P. , Singh Nimmi , Mishra Navin
Published: May 2022

Rationale

Odontomas result from abnormal growth of differentiated epithelial and mesenchymal cells, which form ameloblasts and odontoblasts along with pulp tissue at times.

Patient Concerns

A patient reported with a chief complaint of hard swelling of the lower jaw causing difficulty in mouth opening and facial deformity.

Diagnosis

A provisional diagnosis of complex odontome based on clinicoradiological findings was made, which was later confirmed as complex composite odontome histologically.

Treatment

Bilateral hard tissue mass was surgically removed from the mandible with utmost precaution to prevent jaw deformity. On fine separation, the specimen yielded nearly 82 small teeth-like structures.

Outcomes

Histopathologically, multiple small teeth-like structures with haphazardly arranged central fibrofatty pulpal stroma surrounded by well-formed dentinal tubules and empty areas representing decalcified enamel matrix surrounded by fibrovascular stroma at the periphery were seen.

Take-away Lessons

Early diagnosis and treatment ensures minimal surrounding deformities, better prognosis, and less chances of recurrence.

We presented a case of uncontrolled genital bleeding caused by subserosal fibroid and treated by robotic-assisted hysterectomy during the coronavirus disease 2019 (COVID-19) pandemic. A 49-year-old woman had severe anemia with hypermenorrhea due to submucosal fibroid. Hysterectomy was deemed necessary to control genital bleeding. However, at that time, the number of confirmed COVID-19 cases has been increasing in Japan. Serious concerns have been raised about the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) dissemination during minimally invasive surgery due to pneumoperitoneum-associated aerosolization of particles. We tried to prevent the spread of surgical plume by performing surgery under low pneumoperitoneal pressure at 6 mmHg and by using an evacuation/filtration system. As a result, we successfully performed robotic-assisted hysterectomy with minimized risk of spreading surgical plume-containing aerosol particles into the operating room. It is essential to follow the guidelines issued by the relevant societies and act accordingly to reduce the risk of SARS-CoV-2 infection in medical settings while performing surgery. We hope that our experience will help prevent secondary cases of future SARS-CoV-2 infections.
Fallopian Tube Autoamputation after Acute Large Endometrioma Torsion
Authors: Atileh Luay Ibrahim Abu , Khalifeh Nouf Moh’d
Published: May 2022

Adnexal torsion is the fifth most common gynecological emergency. However, endometrioma torsion is a very rare entity due to the associated pelvic adhesions. A 26-year-old woman presented to the emergency department complaining of acute lower abdominal pain for the past 6 h. Physical examination showed localized left iliac fossa tenderness. Ultrasound showed a 13 cm endometrioma with a normal color Doppler. Laparoscopy revealed a 13 cm large endometrioma arising from the left ovary. The left Fallopian tube was amputated at its attachment to the left cornua. Reconstruction of the ovary was done and the specimen was retrieved through the umbilicus inside a bag. Autoamputation of the Fallopian tube alone, although very rare, is typically associated with a preceding torsion. It is critical to be aware of adnexal torsion, as it can have implications for future fertility. Therefore, laparoscopic detorsion and cystectomy are the gold standard management.

Vulvar angioleiomyoma is a very rare neoplasm. We describe the case of a 49-year-old woman who presented with a small, firm, tender labial mass. Intraoperatively, the lesion appeared hypervascular and was excised using sharp dissection. Histological and immunohistochemical analyses were necessary to make the diagnosis. The report of this extremely uncommon gynecologic lesion is important to make clinicians aware of the possibility of vulvar angioleiomyoma.

Published: May 2022

Objective:

Connections between craniocervical posture (CCP) and changes in teeth position have already been demonstrated; however, the defined pathway of relationship is still not clear. The aim of this study was to evaluate CCP modifications after rapid maxillary expansion therapy using rapid palatal expansion therapy (REP)/McNamara appliances.

Materials and Methods:

A consecutive series of 35 subjects, aged between 6 and 14 years, with no prior history of orthodontic treatment, and requiring skeletal expansion of the upper arch, were selected and analyzed. All patients were treated with REP or Mcnamara appliance: the active phase of 15 days and retaining phase of 6 months. Cephalometric analysis was carried out before (T0) and after (T1) orthodontic therapy evaluating changes in the craniofacial area and those related to CCP. The obtained data were statistically analyzed for the pre-post changes.

Results:

No statistically significant difference emerged indicating a modification in the CCP measured at T0 and T1 (P > 0.05). Patients treated with the McNamara appliance, compared to those treated with REP, showed a higher value of the angle OPT ^ Ver (P = 0.021), and a lower measure of the angles CVT^EVT (P = 0.035) and EVT^Ver (P = 0.023). Furthermore, patients treated with REP showed a higher hyoid angle value than those treated with McNamara (P = 0.047).

Conclusion:

This study did not reveal any relationship between the application of palatal expansion therapy and changes in CCP.
The effect of various nanoparticle coating on the frictional resistance at orthodontic wire and bracket interface

Published: May 2022

This systematic review was aimed to test the null hypothesis that coating of orthodontic wires with nanoparticles does not affect the frictional properties at bracket--wire interface. Electronic database searches were performed up to September 2020. In vitro studies were considered for reviewing process. Study selection, data extraction, risk of bias assessment was performed during reviewing process. Only qualitative analyses of included literature were done due to the presence of heterogeneity among the studies. Out of 1,068 retrieved records, nine studies satisfied the inclusion criteria and included in this review. Studies were assessed at low risk to high risk of bias according to certain parameters. Wide variety of nanoparticles were used for surface coating of orthodontic wires of variable sizes, shapes, and materials like stainless steel, NiTi, and TMA and placed into the slots of different types of orthodontic brackets to evaluate the alteration in frictional and other mechanical properties. Most of the studies clearly indicate that coating with nanoparticles decreases the friction between wire and bracket interface under specified in vitro conditions. Furthermore, among the nine included studies, only two considered evaluation of effect of coated brackets on frictional and other mechanical properties and results were heterogeneous. The null hypothesis is rejected and it is concluded that the wires coated with nanoparticles might offer a novel opportunity to substantially reduce frictional resistance at bracket--wire interface during tooth movement. Further studies are necessary to strengthen the evidence regarding effect of coated brackets on frictional properties.

Published: May 2022

INTRODUCTION:

Protraction therapy for maxillary deficiency in the treatment of skeletal class III malocclusion involves the use of facemask. Conventionally facemask has been anchored to the maxillary dentition, which is responsible for some of the counter-productive effects of facemask therapy including backward and downward rotation of the chin, increase in the lower anterior facial height, proclination of maxillary incisors, retroclination of mandibular incisors apart from mesialization of maxillary molars with extrusion and decreased overbite.

AIM:

The aim of this article is to highlight the nuances of Bone-Anchored Maxillary Protraction (BAMP) including a literature review, which is comprehensive and narrative and comparing the different techniques involved such as type 1 BAMP versus type 2 BAMP and BAMP versus facemask.

MATERIALS AND METHODS:

A computerized search was performed in electronic databases such as PubMed, PubMed Central, Cochrane, Embase, DOAJ, and Google scholar using key words such as “bone-anchored maxillary protraction” and “BAMP.” The search was confined to articles in English published till March 2021. Forty-seven case-controlled, cross-sectional, retrospective and prospective studies, as well as systematic reviews and meta-analysis were included in this article, which were limited to human subjects. A hand search of the reference lists of the included articles was also carried out to include missed out articles.

CONCLUSION:

To overcome these drawbacks, BAMP was introduced, which causes both maxillary protraction, restraint of mandibular growth with minimal dentoalveolar changes. BAMP is used widely nowadays in the treatment of skeletal class III malocclusion.
Ion release and surface roughness of silver soldered bands with two different polishing methods
Authors: da Silveira Ramiro Estacia , Gonçalves Tatiana Siqueira , de Souza Schacher Helena Reis , de Menezes Luciane Macedo
Published: May 2022

OBJECTIVE:

To evaluate the surface roughness and ion release of silver-soldered joints by using two polishing methods.

METHODS:

174 orthodontic bands with and without silver-soldered joints were evaluated and divided into three groups: two experimental, with different polishing methods (SP1 and SP2), and one control (SS) composed of bands without silver solder. For ionic release, 50 bands of each group were immersed in saline solution and submitted to atomic absorption spectrophotometry to quantify the amount of Fe, Ni, Cr (in all the three groups), Ag, Cu, Cd, and Zn (in the two experimental groups). A rugosimeter was employed to verify the surface roughness.

RESULTS:

Ni and Cr were released in higher amounts after soldering. Cd, Ag, Zn, and Cu may be released from silver-soldered bands independently of the polishing method employed. Ag was released in higher amounts from the soldered bands that presented higher surface roughness.

CONCLUSIONS:

Differences exist in relation to the surface roughness of silver-soldered bands when distinct polishing methods are used. Toxic ions may be released from silver soldered joints and higher surface roughness may cause higher ionic release.
