Authors: Man Fransiscus Harri Dwi Kurniawan , Joko Sutopo
Published: December 2023

Kebugaran jasmani merupakan suatu bentuk kemampuan dengan menyesuaikan berat dari tubuh manusia yang harus dipenuhi seseorang agar dapat melakukan segala aktivitas atau kegiatan sehari-hari tanpa ada rasa lelah ataupun gangguan pada tubuh. Kebugaran jasmani juga dapat digunakan untuk mengetahui bagaimana kondisi kesehatan jantung dari berapa kali pengguna melakukan gerakan beserta BPM (Beat per Minutes). Dalam melatih kebugaran jasmani ini terdapat beberapa gerakan yang dapat dilakukan, dalam aplikasi monitoring ini menggunakan gerakan push-up, squat, jumping jacks. Terkadang orang lupa dalam menghitung berapa kali mereka telah melakukan gerakan-gerakan tersebut bahkan tidak tahu berapa detak jantung yang mereka dapatkan selama latihan kebugaran. Dengan hal inilah dibangun sistem monitoring untuk melacak pergerakan tubuh beserta kondisi kesehatan jantung dalam latihan kebugaran jasmani yang menggunakan basis IoT atau kepanjangan dari Internet of Things. Sistem ini menggunakan aplikasi android dengan dihubungkan pada perangkat IoT yang lalu dihubungkan melalui sebuah modul wifi yaitu ESP8266 untuk mengirimkan data ke aplikasi android. Dengan adanya aplikasi monitoring latihan kebugaran berbasis iot diharapkan dapat membantu, memudahkan, memotivasi dalam berolahraga
Evaluation of the environmental exposure risks of pesticides used in vegetable production in Türkiye
Authors: Kula Elif Pınar , Göktaş Recep Kaya
Published: December 2023

In this study, first, a list of pesticides that can potentially pose environmental exposure risks was compiled by analyzing the recent literature on residue levels in fresh vegetables produced in Türkiye. Then, by using the fundamental environmental partitioning properties of these pesticides, their potential multi-media environmental distributions were assessed. Acetamiprid, chlorpyrifos, and pyridaben were among the pesticides that frequently exceeded the residual limit values. Multi-media environmental modeling was conducted for these three pesticides using an evaluative four-compartment (air, soil, water, sediment) model. Compartmental distributions, inter-compartmental mass transfer rates, advective, and reactive losses were estimated for the selected pesticides after their simulated application to soil. The ranking of overall persistence among the pesticides was found to be pyridaben > chlorpyrifos > acetamiprid. The percentage mass distribution of acetamiprid in water was higher due to its low volatility and high solubility. The overall persistence of chlorpyrifos was limited by its higher partitioning to air although it is more persistent than pyridaben in other compartments. To investigate the residue dynamics of the three pesticides in tomato crops, temporal changes in harvest fractions were compared using the regression equations of the crop model dynamiCROP. Acetamiprid was estimated to be taken up at higher rates in tomatoes after initial application. The residue dynamics of chlorpyrifos and pyridaben were found to be similar. The quantitative methods in this study can be used to assess the environmental risks associated with commonly used pesticides in Türkiye and to address the issue of exceeding residue limits in agricultural products.

Informantes católicos en el mundo azucarero
Authors: Gutiérrez Florencia , Santos Lepera Lucía
Published: December 2023

A principios del siglo XX, la Liga Democrática Cristiana envió a Tucumán a tres expedicionarios con el propósito de relevar las condiciones socio-laborales de los obreros azucareros. El viaje les permitió conocer, describir e informar a la dirigencia de la Liga sobre ese mundo distante y desconocido, que consideraban era imperioso intervenir para mejorar las condiciones de vida obrera y frenar el avance del socialismo. En el cruce de las aspiraciones de cientificidad, basadas en la observación directa, y los preconceptos clasistas y prejuicios morales, el diagnóstico promovió interrogantes y posibles respuestas para avanzar en la organización obrera. La travesía  de los expedicionarios católicos, plasmada en el libro  Por los ingenios de Tucumán. Impresiones de viaje, permite repensar una inédita experiencia de conocimiento, vinculación y acción nacida del catolicismo social a principios del siglo XX. El reto de este artículo es contribuir a una historia social interrelacionada que privilegie la mirada en torno a las posibilidades, incertidumbres y desafíos del catolicismo social para construir un diagnóstico del mundo azucarero y generar propuestas de acción en el norte argentino.

Resilient Assemblages: Expanding Access and Equity through Practices of Piggybacking
Authors:   University of Arkansas, HOLLAND BRIAN
Published: December 2023

Piggybacking Practices” is an ongoing research project and recent virtual exhibition and symposium presenting one possible approach to expanding access and equity in the designed environment through incremental, opportunistic means. Piggybacking practices are defined here as multiple- use propositions capable of anchoring undercapitalized activities alongside other more traditional forms of urban development. Piggybackings exploit gaps or niches in the logics and economies of conventional spatial practice while assembling disparate actors together into new and more equitable and resilient forms of collectivity.
Charlottesville vs. Chengdu: Is It Possible to Engage the Community and Fight Back Unsustainable Urban Retail Models?
Authors:   University of Michigan, LIANG NAN , PALLARES ANA MORCILLO ,   University of Michigan
Published: December 2023

Shopping is arguably the last remaining form of public activity.”1 Rem Koolhaas stated twenty years ago. Through increasingly predatory forms, shopping has infiltrated and colonized urban life. From the explosion of suburban shopping centers in the mid-20th century to today’s specialized big-box stores with highly computerized goods-tracking systems, this paper calls for a reformulation of alternative models of retailing. One that engages the community and challenges citizens’ demands. How to fight back unsustainable urban retail models and have the shopping center be a balanced urban ecosystem becomes a crucial question to answer now. From this approach, the research discusses a comparison between two examples: Downtown Charlottesville in Virginia by Anna and Lawrence Halprin (1976) and the Chengdu Sino-OceanTaikoo Li by Oval Partnership (2014). Although these two projects are nearly four decades apart and have very different socio-cultural and political backgrounds, both align the formula of the shopping street as an antidote to the current unsustainable urban mechanisms that perpetuate inequality.
Investigating the Adaptive Reuse of Decommissioned Cruise Ships
Authors:   CallisonRTKL, DESOOKY IBRAHIM , MILLER YASAMIN ,   YMG Group
Published: December 2023

The rapid influx in cruise ship decommissioning during 2020 has created a unique opportunity to recycle or repurpose large ships using innovative strategies. This report examines the potential for the conversion of decommissioned cruise ships for housing, with a focus on the Miami-Dade County area. The goal was to investigate an alternative mode of coastal living, taking advantage of the oversupply of decommissioned ships as a primary housing structure, using semi-permanent docking in available port spaces. We identified case studies of residential cruise ships to serve as relevant precedents. We collected and synthesized raw data on the specifics of size, tonnage, capacity, age, and cost of the decommissioned ships of the year 2020, creating key datasets highlighting the magnitude of the issue. We then investigated the engineering feasibility of a docked residential cruise ship in Miami, conducting interviews with engineering practitioners having marine terminal expertise. Finally, we conducted an on-line survey to 362 adults in Miami-Dade County, (Qualtrics) to investigate perceptions from potential residents of this new living concept. We found that residential cruise ships could be moored in developed areas, such as the Port of Miami, but that infrastructure costs would be considerable, and the need for hurricane evacuation would be an issue for prospective residents. Our survey results strongly supported the proof- of-concept, with respondents expressing (88% yes or maybe) interest in living on a repurposed cruise ship. Those expressing the greatest interest are 41-50 years of age, earning at least $100,000 per year, who are single or have children, and willing to pay $849(mean) and $4000(max) per month.
« Leave thy home, O youth, and seek out alien shores » : dépaysement et nostalgie dans A Time of Gifts de Patrick Leigh Fermor
Authors: Blanchet Béatrice
Published: December 2023

Cette contribution explore l’expérience du dépaysement, conçu comme reconnaissance d’une altérité irréductible mais également comme domestication de l’étrangéité, dans A Time of Gifts, œuvre de l’écrivain britannique Patrick Leigh Fermor (1915-2011) qui retrace les prémices d’un périple effectué à pied de Londres à Istanbul (1933-1935). Faisant des territoires de l’altérité un enjeu de savoir et de pouvoir, le regard impérial s’est également déployé en Europe centrale, territoire de l’Autre proche. Le récit de Patrick Leigh Fermor semble constituer une exception notable au sein d’un genre fréquemment marqué du sceau de l’ethnocentrisme. L’étrangéité est appréhendée au prisme d’une culture classique conçue comme universelle, dont les références partagées définissent les géographies symboliques du proche et du lointain. L’altérité est dès lors fréquemment assimilée au familier, ce qui fait du dépaysement un retour aux origines autant qu’un détour vers l’inconnu. Le dépaysement conçu comme écartement et séparation demeure néanmoins une expérience fondatrice, décrite par Patrick Leigh Fermor comme conversion ontologique. Indissociable d’une réflexion sur le statut liminal de l’insider-outsider, l’expérience de l’étrangéité peut être appréhendée comme un rite de passage impliquant l’ébranlement des évidences ainsi que le devenir-autre. Le dépaysement est éprouvé dans une dimension spatiale en tant que franchissement géographique mais également dans son épaisseur temporelle dotée de polyphonie : publié en 1977, A Time of Gifts mêle ainsi la voix d’un jeune homme découvrant une Europe au bord de l’abîme aux réflexions de l’homme de lettres parvenu à maturité, expérimentant comme arrachement l’irréversible destruction des êtres et de lieux par les tragédies de l’Histoire. Cette oscillation narrative et mémorielle entre l’ici et l’ailleurs, mais également entre le présent et le passé, fait de la nostalgie – étymologiquement associée à l’éloignement des lieux familiers et à l’abolition du passé originel – le contrepoint indissociable du dépaysement.
Le corps dépaysé : la migration transsexuelle et la prostitution dans le récit de voyage brésilien A Princesa
Authors: Fois-Braga Humberto
Published: December 2023

A Princesa: depoimentos de um travesti brasileiro a um líder das Brigadas Vermelhas (1995) [Princesse : les déclarations d’une travestie brésilienne à un leader des Brigades Rouges] est un récit mémorialiste écrit à partir de notes prises par la transsexuelle et prostituée brésilienne Fernanda Alburquerque alors qu’elle purgeait une peine de prison en Italie dans les années 1990. Fernanda raconte sa vie depuis son enfance au sertão (région pauvre, aride et traditionnelle du Nord-est brésilien) jusqu’au moment de son arrestation en Italie. Cet article propose de dévoiler comment la mobilité physique de Fernanda, qui a parcouru et vécu dans une dizaine de villes brésiliennes et européennes, aura des conséquences dans la construction d’une performance de son corps transsexuel. Ensuite, et toujours par rapport à ce trajet plein de préjugés et de découverte de sa sexualité, notre recherche se penchera sur les motivations qui ont amené Fernanda à avancer dans son projet de migration, tandis qu’elle est incapable de retourner chez sa mère. On s’aperçoit pour finir que Fernanda se trouve toujours en mouvement parce qu’elle n’arrive jamais à concevoir de façon harmonieuse sa sexualité et son plaisir dans les frontières chrétiennes hétérosexuelles. Ainsi, son corps, qui devient performant et palimpseste, se présente comme une allégorie de ses dépaysements, car il est plein de cicatrices, de chirurgies et finit enfermé dans une prison. À partir de cette appréhension archiviste du corps, on verra que les transsexuelles immigrées se trouvent deux fois déplacées : lorsqu’elles décident de remodeler, de reconstruire et de réarranger leur corps, elles troublent les archives sexuelles et nationales légitimées par la société traditionnelle.
Une femme dépaysée. Dove mi trovo de Jhumpa Lahiri
Authors: De Balsi Sara
Published: December 2023

Dans Dove mi trovo (Guanda, 2018), premier roman en italien de l’écrivaine américaine Jhumpa Lahiri, déjà autrice d’une autobiographie translingue au titre parlant (In altre parole, Guanda 2014 / En d’autres mots, traduction française publiée par Actes Sud en 2015), une femme dont ne sont donnés ni le prénom ni la nationalité, évolue dans une ville non précisée d’Italie. Seule, sans enfants, âgée d’une quarantaine d’années, elle vit dans un appartement qui ne lui appartient pas. Au cours du roman, pour son travail de chercheuse, elle est amenée à participer à une conférence où elle croise un homme âgé, étranger, important philosophe. Peu de temps plus tard, elle apprendra son décès en lisant le journal. Mon hypothèse – aussi indémontrable que fascinante – est que le philosophe que la narratrice rencontre est inspiré de la figure de Tzvetan Todorov, disparu en février 2017, plus ou moins dans la période où Lahiri écrivait son roman ; plus précisément, il serait celui que la critique a appelé le « second Todorov », l’auteur, notamment, de l’autobiographie intellectuelle L’Homme dépaysé (Seuil, 1996). Dans cet essai, Todorov envisage autobiographiquement le dépaysement comme une expérience – éminemment individuelle – de décentrement, d’étonnement et de désorientation, qui lui a apporté de nombreuses découvertes et enseigné l’art de la curiosité et un certain relativisme culturel. Je formule donc l’hypothèse que Lahiri a lu le « second Todorov » et a fait sienne cette conception, allant jusqu’à (peut-être) insérer dans le roman un petit hommage au philosophe. Dans cette contribution, après avoir présenté brièvement la conception todorovienne de dépaysement, je propose une lecture du roman Dove mi trovo à la lumière de celle-ci.
Traduire le dépaysement : comment recréer le Riddleyspeak de Russell Hoban en français ?
Authors: Buhl Virginie
Published: December 2023

Dans Riddley Walker de Russell Hoban, le dépaysement procède à la fois du linguistique, du cognitif, de la narrativité et du fictionnel. Ce roman expérimental propose une expérience de lecture qui déclenche une immersion dépaysante dans un autre espace-temps. L’intrigue se situe dans une Angleterre post-apocalyptique défigurée par une explosion atomique. La topographie de la région dans laquelle se déroule l’action ne ressemble plus que vaguement au Kent et tous les noms de lieux semblent, à la première lecture, à la foi inconnus et étrangement familiers. Cette perte des repères cognitifs habituels constitue une invitation au voyage et lance la personne qui lit dans un jeu de pistes puisque la narration et le style sont également vecteurs de dépaysement : le narrateur homodiégétique est Riddley Walker, un jeune garçon de 12 ans. Comme son nom l’indique, il promène ses lecteurs au gré d’un récit inabouti qui obéit à sa logique propre et il s’exprime dans une langue étrange, énigmatique et fortement marquée par l’oralité : le Riddleyspeak. Cette langue transfigure la réalité et défamiliarise le lecteur qui, forcé de lire autrement, perd momentanément ses automatismes. L’écriture de la version française de ce roman – l’opération par laquelle le texte source a été transplanté dans une nouvelle langue-culture – a constitué en soi une nouvelle aventure placée sous le signe du dépaysement pour le traducteur. Nicolas Richard a dû s’approprier le Riddleyspeak pour créer une nouvelle langue, le Parlénigm qu’il s’agissait de parler couramment, comme une langue étrangère.
DISTRIBUIÇÃO DOS ÓBITOS POR ACIDENTE DE TRÂNSITO DO ESTADO DE ALAGOAS EM 2019 E ANÁLISE DA DESIGUALDADE EM SAÚDE
Authors: Lúcia Alves Lima Ana , Aquino Érika
Published: December 2023

Objetivo: traçar o perfil de mortalidade por acidentes de trânsito no Estado de Alagoas, no ano de 2019, ressaltando as variáveis: sexo, faixa etária e raça/cor, e como objetivos específicos realizar a análise de desigualdades e a distribuição espacial dos acidentes segundo município de residência. Métodos: Estudo ecológico da mortalidade por acidentes de trânsito utilizando relatórios do TABNET/DATASUS com os dados de mortalidade, a ferramenta “EQUIPLOT” para a análise das desigualdades e o aplicativo de mapas QGIS 3.10.9 para a visualização dos óbitos por município. Resultado: Alagoas registrou 616 óbitos, com maior incidência nos acidentes com motocicletas, que corresponde a 47%. Deste total de óbitos envolvendo motociclistas, 84% eram do sexo masculino, 48% estavam na faixa etária jovem de 20 a 39 anos, 95% foram declarados pardos, o estado civil solteiro compreendia 61,04%, e a escolaridade com 7 ou menos anos de estudo foi de 44,16%. A análise das desigualdades apontou que pertencer ao sexo masculino, estar na faixa etária jovem e ter cor parda se constituiu em fator de risco para óbitos por acidentes. Na distribuição espacial, Alagoas apresentou maior número de óbitos na 1ª e 7ª regiões de saúde onde estão os municípios de Maceió, capital do Estado e de Arapiraca. Da 1ª a 4ª regiões de saúde a maioria dos óbitos foi por veículos terrestres, e da 5ª a 10ª região, por motocicletas. Conclusão: É bem verdade que o aumento da frota de automóveis e motocicletas propiciou aumento no número de acidentes, porém faz-se necessário a adoção de políticas de forma sistemática e integrada, como medidas de maior impacto para a redução do comportamento inadequado dos usuários no trânsito e, por conseguinte, dos acidentes e mortes.

Palavras chaves: Acidentes, Motocicletas, Registros de Óbitos, Desigualdades em Saúde, Distribuição Espacial.
Renesanční sklo z Opavy. Sklo jako nedílná součást renesanční kultury stolování, obchodní komodita i prostředek demonstrace společenského postavení / Renaissance Glass from Opava. Glass as an Integral Part of Renaissance Dining Culture, a Commercial Commodity and a Means of Expressing Social Status
Authors: Vaďurová Kateřina
Published: December 2023

Předkládaný příspěvek poskytuje základní přehled archeologických nálezů skel renesančního tvarosloví ze 2. poloviny 16. až 1. poloviny 17. století z Opavy a analyzuje je v kontextu Slezska a severní Moravy, ale i v širším kontextu zemí Koruny české. Materiálovou základnu práce tvoří sklo z deseti lokalit nacházejících se především v historickém centru města. Většina materiálu pochází z výzkumů Národního památkového ústavu, ÚOP v Ostravě, realizovaných v průběhu uplynulých 60 let, méně ze sbírek Slezského zemského muzea. Příspěvek nepředstavuje pouze typologickou analýzu materiálu, ale zkoumá také chemické složení vybraných vzorků skel za účelem identifikace výrobních okruhů a obchodních vazeb. Přestože obecné vývojové tendence jsou v českých zemích stejné, na základě materiálu z Opavy lze postihnout mírně odlišný vývoj v porovnání s moravskými a českými městy.

The article provides a basic overview of archaeological finds of Renaissance glasses from the second half of the 16th to the first half of the 17th century from Opava and analyses them in the context of Silesia and north Moravia as well as in the broader context of the Lands of the Bohemian Crown. The article works with glass from ten sites located primarily in the historical centre of the town. Most of this material comes from excavations conducted by the Ostrava branch of the National Heritage Institute over the past 60 years, to a lesser extent artefacts from the collections of the Silesian Museum. In addition to a typological analysis of artefacts, the essay also investigates the chemical composition of selected glass samples in order to identify production circles and trade connections. Although general development trends are the same throughout the Czech lands, the material from Opava makes it possible to distinguish slightly different development in comparison with Moravian and Bohemian towns.

Authors: Betancur Sánchez Alexander , Roa Solange , Parraguez Marcela
Published: December 2023

Se presenta evidencia empírica sobre las estructuras y mecanismos mentales necesarios para el aprendizaje del concepto de eigenvalor y eigenvector a partir de la transformación lineal, usando el paradigma de investigación de la teoría APOE (Acción, Proceso, Objeto, Esquema). Los datos del estudio son el resultado de la implementación de la enseñanza con base en un modelo cognitivo (Descomposición Genética) situado en un curso regular de álgebra lineal de una universidad pública en Colombia. La evidencia empírica permite mostrar un modelo cognitivo refinado con relación a las estructuras y mecanismos clave, para dar cuenta de los Procesos subyacentes al Proceso de eigenvalor y eigenvector y generar la discusión en relación con la totalidad del Proceso. Las recomendaciones para la enseñanza precisan la importancia de propiciar diversas situaciones que involucren la transformación lineal y su coordinación con los Procesos: vector cero - no es un eigenvector; conjunto solución de T(v)=λ_0v; espacio nulo y determinante.

Authors: Moreno-Pino Francisco Manuel , Jiménez-Fontana Rocío , Romero-Portillo Daniel
Published: December 2023

This article presents the results of the analysis of the development of sustainability competencies of students enrolled in subjects in the area of ​​Didactics of Mathematics of three different degrees in the Faculty of Educational Sciences at the Universidad de Cádiz. To carry out this analysis, the sustainability questionnaire of the EDINSOST project was used. This questionnaire consists of 18 items related to the development of the four sustainability competencies proposed by the Sectoral Commission of the Conference of Rectors of Spanish Universities. A total of 105 students responded to a questionnaire composed of items expressed like a four-point Likert scale. Three types of composite indicators were defined to analyse the students’ answers in each competency, competency unit, and mastery level. The results reveal how the development of the sustainability in students depends on the degree analysed.
Towards a socio-ecological practice of mathematics teacher education
Authors: Coles Alf
Published: December 2023

This theoretical article is a response to UNESCO’s call for a new social contract for education, in the context of mathematics teacher education. The article sets out four principles behind “socio-ecological” practices in mathematics education: not taking nature as a fixed background for concerns; avoiding the epistemological error of taking the individual as the unit of learning; questioning what is centred in our work; moving towards a dialogic ethics. The article considers the “what” and the “how” of mathematics teacher education, from this socio-ecological perspective. In terms of the “how”, it is argued a dialogic ethics prompts attention to the potential for a mathematics teacher educator taking a “meta-perspective” in relationships with prospective teachers, recognising those prospective teachers as “teachers”, from the start of a teacher education course. In contexts where the “what” of mathematics teacher education is highly constrained, the “how” of socio-ecological practices may still be possible to enact.
Conceptualizando el proceso de transformación de un profesor de matemáticas en relación con la enseñanza de las matemáticas y la justicia climática: la historia de Karl
Authors: Helliwell Tracy , Hennessy Lauren , Bushnell Karl
Published: December 2023

La historia de Karl tiene como objetivo mostrar la complejidad que implica abordar cuestiones de justicia climática como profesor de matemáticas. Presentamos un texto en capas como proceso y producto de nuestro análisis para exponer la forma en que un profesor de matemáticas de secundaria, Karl, acepta las contradicciones y recurre a múltiples formas de conocimiento durante su proceso de transformación en relación con la enseñanza de las matemáticas y la justicia climática en el contexto de un programa de desarrollo profesional a pequeña escala. Ilustramos las diferentes formas en que Karl conceptualiza y pone en práctica la enseñanza de las matemáticas y la justicia climática antes de presentar un marco que llamamos Teaching Mathematics 4 Climate Justice (TM4CJ), que consta de cuatro dimensiones. Mostramos que TM4CJ es relevante para la enseñanza de las matemáticas más allá de las lecciones donde el contenido se relaciona directamente con cuestiones de justicia climática, hacia una forma de ser profesor de matemáticas. Se discuten las implicaciones para la formación del profesorado de matemáticas y el desarrollo profesional.

Published: December 2023

Echinodermata are found quite commonly in the tidal areas of Lembeh Island but their diversity and abundance have not been well documented. The purpose of this study was to determine the types of Echinoderms and their abundance at Pancuran Beach, Lembeh Island, Bitung City. Samples were taken at two stations using the Lincoln-Smith Transect method 2 x 50 m which was stretched perpendicular to the beach with three replications. Samples were identified in situ and the number of individuals of each species was noted. The results showed that in Pancuran Beach there were 18 species of phylum Echinodermata; with details of 7 species from the Asteroidea class, 5 species of Echinoidea, 4 species of Ophiuroidea, 2 species of Holothuroidea. The results of the analysis using the diversity index show that the diversity of Echinodermata at both stations is in the medium category, characterized by the value of H' = 2.06 for station I and H'= 2.35 for station II.  At station 1, the type of Ophiocoma erinaceus has the highest density of 15 ind/100m2 and a relative abundance of 23.68%. At station II Echinothrix diadema has the highest abundance of 12 ind/100m2 with a relative abundance of 17.14%. Common species found in both stations are Diadema setosum, Echinometra mathaei, Echinothrix diadema, Holothuria atra, Ophiocoma erinaceus, and Ophiocoma scolopendrina.

A New and Practical Method for Measuring Sponge Spicules
Authors: Rieuwpassa Frets J. , Tomasoa Aprelia M. , Palawe Jaka F. P. , Rieuwpassa Fredrik , Mege Revolson Alexius , Balansa Walter
Published: December 2023

Binocular light microscopy (BLM) is an excellent match for a scanning electron microscope (SEM) and a trinocular light microscope equipped with a micrometer (TLM). The practicality, user-friendliness, and short-time analysis of BLM make this method a good choice for spicule analysis. However, its effectiveness and accuracy are yet to be confirmed. This study aimed to validate the effectiveness of BLM by comparing its usefulness to both TLM and the gold standard methods. BLM was first subjected to measuring megascleres and microscleres of 2 sponges. Then, by using the If function built-in Excell and t-test in SPSS 16.0, the compatibility of BLM was evaluated against SEM by measuring the length of spicules from 4 Sangihe sponges and their counterpart species from different locations. Furthermore, the t-test analysis was used to validate the compatibility and effectiveness of our method to the TLM by measuring the spicules of four sponges. Both the F-function and the t-test analysis proved BLM was compatible with SEM with both measurements showing a perfect match for megascleres typed spicules of 4 compared sponges. This new technique also showed a perfect match with SEM (p = 0.367, t-test) and with TLM (p = 0.963, t-test).

Exploring Metabolites Of Green Algae Caulerpa Spp. To Discover Putative Inhibitors Of Dpp-4, A New Antidiabetic Target Protein
Authors: Balansa Walter
Published: December 2023

Diabetes mellitus (DM) remains a serious global health threat, claiming a million lives every year and affecting nearly 9% of the adult population who suffer from this impaired insulin sensitivity disease. The Dipeptidyl peptidase-4 (DPP-4) enzyme has recently attracted attention because of its crucial role in insulin signaling, making this enzyme an interesting and emerging target for antidiabetic drug discovery. This study aimed to explore reported metabolites from marine algae of the genus Caulerpa as DPP-4 inhibitors through computational studies using CB-dock 2, Protein-Ligand Interaction Profiler, SwissAdme, and pkCMS. Molecular docking allowed the identification of 7 hit compounds with strong binding affinities (8.4 kcal to 9.3 kcal/mol) against DPP-4 target enzyme PDB ID: 3G4I. Four hits showed stronger binding affinity than two DPP-4 specific inhibitors and FDA-approved antidiabetic drugs, sitagliptin (8.4 kcal/mol) and linagliptin (9.0 kcal/mol). Following a molecular modification of the hit compounds using a bioisosterism-like approach and ADMET evaluation with pkCMS, three putative DPP-4 inhibitors were identified. They showed either stronger binding affinities or better ADMET profiles than sitagliptin and linagliptin, suggesting their promising potential as DPP-4 inhibitors. However, further optimized bioisoterism, in silico and in vivo studies, and clinical-based trials are required to confirm their antidiabetic activity.

Valorização do magistério da educação básica: análise sobre aplicação do piso salarial nacional na remuneração dos professores
Authors: De Morais Cunha Rodrigues Sandra , Sales Luis Carlos
Published: December 2023

Resumo: Este artigo trata de estudo que delineia como objetivo analisar a aplicação da política de valorização salarial de docentes da Educação Básica brasileira após a Lei 11.738/2008. Consiste em uma pesquisa de abordagem quantiqualitativa, com base em dados secundários, primordialmente produzidos e disponibilizados pelo INEP (Instituto Nacional de Pesquisas Educacionais Anísio Teixeira), em formato de Microdados. A população amostral delimitada constitui-se de professores de 5º Ano do Ensino Fundamental, de escolas das redes públicas municipais e estaduais do território brasileiro, que responderam ao questionário da Prova Brasil, edição 2017, um total de 15.997 sujeitos. O processo fundamental para a análise dos dados quantitativos foi a estatística descritiva, com auxílio do programa SPSS (Statistical Package for the Social Sciences). A partir dos procedimentos de análise, considerando o piso salarial nacional do magistério estabelecido para 2017, que era de R$ 2.455,35, pode-se inferir que, em termos de salário bruto, a maioria das instituições da rede municipal paga abaixo do valor do piso, descumprindo o que está estabelecido na referida lei. Concluiu-se que a valorização profissional do magistério na educação básica requer a estruturação e implantação de uma carreira que possibilite avanços remuneratórios, significativo vencimento inicial e final, valorização das titulações e incentivo à formação inicial e continuada, bem como boas condições de trabalho para os docentes.

Resumo: O presente artigo tem como objetivo apresentar um relato de experiência que contempla a aplicação de uma Sequência Didática (SD), composta por atividades plugadas e desplugadas com o intuito de promover a aprendizagem dos pilares do Pensamento Computacional na educação infantil. Para a condução da investigação foi realizado um estudo de caso com uma turma de Pré-escola II, com uma média de oito alunos, em uma escola Municipal de Educação Infantil de Gravataí, RS. A SD, no contexto do presente trabalho, tem a finalidade de auxiliar o planejamento do professor, atuante na Educação Infantil, e apresentar como os pilares do Pensamento Computacional podem ser aplicados de forma intencional, considerando os campos de experiência da Base Nacional Comum Curricular (BNCC). A ideia é apresentar ao docente como o pensamento computacional pode ser adotado para abordar algumas das habilidades e competências previstas na BNCC. Para tanto, são explorados os pilares de algoritmos, abstração, decomposição e reconhecimento de padrões em atividades que integram a SD apresentada. O principal resultado obtido compreende uma diretriz que pode servir de ponto de partida para auxiliar os professores a planejarem suas aulas e a aplicarem com outros grupos de estudantes.

Contribuições do design de interfaces no uso de jogos educacionais digitais para o público infantil: revisão sistemática da literatura
Authors: Blaskoski Kellermann Daphne , Franco Márcia Häfele Islabão
Published: December 2023

Resumo: A aprendizagem mediada pelos jogos educacionais digitais (JEDs) tem apresentado contribuições significativas à educação. Pesquisas têm demonstrado que o design visual das interfaces desempenha um papel fundamental nesse contexto, sendo um dos principais problemas relatados em pesquisas na área. Diante disso, este artigo apresenta uma revisão sistemática da literatura (RSL) que buscou identificar o uso e as contribuições do design visual das interfaces dos JEDs para a aprendizagem de crianças de 5 a 12 anos. Os resultados da RSL destacam os benefícios para o aprendizado e ressaltam a escassez de pesquisas que explorem o uso de elementos do design, especialmente no contexto brasileiro. Essa carência de estudos indica claramente a necessidade de estabelecer e aplicar diretrizes e boas práticas para orientar o uso efetivo do design visual nas interfaces dos JEDs, visando aprimorar ainda mais o potencial educacional dessas ferramentas.

Percepções discentes acerca da desordem informacional: um estudo exploratório no ensino fundamental
Authors: Maihub Manara Leonardo , Fonseca Carlos Ventura
Published: December 2023

Resumo: Enquadrada no que pode ser chamado de desordem informacional, a larga disseminação de informações falsas, especialmente a partir da internet, vem se configurando como um desafio colocado para diferentes países, com impactos severos em diversas esferas da vida humana. Esse contexto vem sendo estudado e abordado à luz de diferentes referenciais e sob uma ampla gama de propostas e intervenções. Este texto buscou investigar, sistematizar, discutir e apresentar as percepções de estudantes do Ensino Fundamental acerca do fenômeno da desordem informacional e do compartilhamento de informações falsas. O estudo se realizou no contexto de aulas regulares, na disciplina de Ciências da Natureza, com a participação de 38 estudantes do sétimo ano do Ensino Fundamental, em uma escola pública municipal da região serrana do Rio Grande do Sul. Para atender os objetivos de pesquisa, partindo de uma orientação qualitativa e exploratória, as respostas dos estudantes a questionários e atividades realizadas em aula foram submetidas à análise de conteúdo. Os nossos resultados sugerem que os participantes utilizam critérios similares aos descritos pela literatura para o julgamento da credibilidade de informações, mostram-se advertidos a respeito da desinformação, concebem a intenção de manipular o principal motivo para o compartilhamento de informações falsas, e que o combate à sua disseminação cabe, principalmente, aos usuários e às plataformas de comunicação. Mesmo que muito ainda precise ser explorado, ressalta-se o possível benefício de enriquecer os currículos educativos com propostas que tratem objetivamente da desinformação, no sentido de desenvolver habilidades de Media Literacy e avaliação da credibilidade.

Terjadinya banjir dan genangan yang tidak bisa segera surut masih menjadi salah satu permasalahan di Kabupaten Malang. Padahal juga sudah dilakukan studi analisa dan perencanaan dalam mencegah hal tersebut supaya tidak terulang kembali pada masa yang akan datang. Salah satu masalah utama terjadinya genangan dan banjir di Kecamatan Kepanjen Kabupaten Malang disebabkan karena kinerja sistem drainase yang tidak berjalan sesuai fungsinya. Untuk mengatasi permasalahan tersebut, maka dilakukan analisis untuk meningkatkan sistem drainase supaya bekerja secara optimal pada saluran-saluran di Kecamatan Kepanjen. Analisis yang digunakan yaitu dengan menganalisis curah hujan 10 tahun terakhir menggunakan metode Log Pearson Type III dan Metode E.J Gumbel, sehingga didapatkan debit banjir rencana yang disesuaikan dengan perencanaan yang akan diterapkan dalam pengendalian sistem dranase di lokasi tersebut supaya kinerjanya berjalan secara optimal.Selain analisis debit banjir juga dilakukan analisis topografi, sehingga elevasi kondisi saluran saat ini bisa diketahui atau tidak perubahannya dari beberapa tahun yang lalu. Berdasarkan hasil analisis kondisi kapasitas    saluran eksisting yang ada saat ini , didapatkan 18 saluran yang tidak dapat menampung debit banjir dari curah hujan dan air buangan yang lain di sekitarnya. Salah satu contoh yang terjadi pada saluran sekunder jalan Adi Utomo dengan debit yang tidak tertampung oleh saluran yang ada saat ini. Sedangkan untuk yang tidak memenuhi syarat optimal kinerja saluran, maka dilakukan peningkatan saluran drainase dengan pelebaran saluran atau redesain saluran sehingga kinerja saluran bisa meningkat optmal dengan baik sesuai yang diharapkan
