Authors: Dali-Sahi Majda , Dennouni-Medjati Nouria , Kachekouche Youssouf , Boudia Hamza N.M. , Boulenouar Houssam
Published: October 2019

Background:

The existing literature reports results on the association of lipid parameters with the level of insulin secretion and the risk of arterial hypertension.

Objective:

This
study evaluated the role of the insulin dosage and lipid fractions in the risk of arterial hypertension in type 2 diabetic patients in Western Algeria.

Methods:

This was a cross-sectional observational study involving 101 subjects with type 2 diabetes mellitus. The data collected was about the biodemographic profile of the participants. We performed multiple regressions to test the effect of insulin concentration on the parameters studied.

Results:

The multiple regression analytical study showed that HOMA-IR, BMI and waist circumference were predictors for the insulinemia response variable (P<0.05). It should be noted that in insulinopenia, insulin secretion is positively and significantly correlated with non-HDL-C (P=0.037), and it is also significantly and positively correlated with LDL-C (P=0.042). Multiple regression also shows that SBP and DBP are significantly and positively related to insulin resistance. Our data suggest a possible direct relationship between fasting insulin and blood pressure.

Conclusion:

Monitoring of circulating insulin concentrations is critically important in a population of type 2 diabetics.

Prevalence and Outcomes of Web-Based Health Information Seeking for Acute Symptoms: Cross-Sectional Study
Authors: Aoun Lydia , Lakkis Najla , Antoun Jumana
Published: October 2019

Background

The literature indicates that Web-based health information seeking is mostly used for seeking information on well-established diseases. However, only a few studies report health information seeking in the absence of a doctor’s visit and in the context of acute symptoms.

Objective

This survey aimed to estimate the prevalence of Web-based health information seeking for acute symptoms and the impact of such information on symptom management and health service utilization.

Methods

This was a cross-sectional study of a convenience sample of 287 Lebanese adults (with a response rate of 18.5% [54/291]) conducted between December 2016 and June 2017. The survey was answered by participants online or through phone-based interviews.

Results

A total of 64.3% of the participants (178/277) reported checking the internet for health information when they had an acute symptom. The rate of those who sought to use Web-based health information first when experiencing acute symptom(s) in the past 12 months was 19.2% (25/130). In addition, 50% (9/18) visited the doctor because of the obtained information, and the rest self-medicated or sought a pharmacist’s advice; the majority (18/24, 75%) improved within 3-4 days.

Conclusions

Higher education level and trust in Web-based medical information were two major predictors of Web-based health information seeking for acute symptoms. Seeking Web-based health information first for acute symptoms is common and may lead to self-management by avoiding a visit to the physician. Physicians should encourage their patients to discuss Web-based health information and guide them toward trusted online websites.

Perpaduan Metode Tematik-Interdisipliner dalam Pembaruan Hukum Keluarga Islam
Authors: Darlis Syamsul
Published: October 2019

Tulisan ini merupakan pengusulan metode terhadap pengkajian pembaruan hukum keluarga Islam. Metode tersebut adalah tematik-interdisipliner. Metode tematik berfungsi sebagai sarana memahami Alquran tema per tema dari ayat-ayat yang memiliki semangat yang sama dalam struktur makna yang lebih universal tanpa adanya dilema parsial dan ekslusif dalam memahami ketetapan hukum yang terkandung di dalamnya. Adapun metode interdisipliner, menggabungkan dan melibatkan beberapa disiplin keilmuan untuk menyelesaikan masalah yang dihadapi (problem solving). Tujuan perpaduan metode tersebut dalam pembaruan hukum keluarga Islam adalah menciptkan pengkajian hukum Islam yang lebih terbuka dan universal, sehingga hasil penetapan hukumnya dapat berlaku proporsional, berkeadilan dan adaptif-konteks. Seperti penetapan hukum jumlah bagian harta waris bagi laki-laki dan perempuan, dua banding satu (2:1). Proses pembagian harta waris didasarkan pada semangat keadilan dan kesejahteraan ekonomi di antara keduanya, yaitu memperhatikan kondisi ekonomi, potensi dan karir si ahli waris untuk menetukan jumlah yang didapat ahli waris tersebut. Tujuan dari perpaduan metode tematik-interdisipliner terhadap pembagian waris laki-laki dan perempuan adalah; (1) proses pembagian waris berlaku secara bijakasana, karena dilakukan melalui musyawarah keluarga, (2) terciptanya keadilan dan kesejahteraan ekonomi di antara keduanya, karena pembagian harta waris didasarkan pada kondisi, potensi dan karir ahli waris, (3) meminimalisir pertikaian diantara keduanya mengenai jumlah bagian harta waris.
Pengabaian Kewajiban Istri karena Nusyuz Suami (Studi Penafsiran Imam Al-Thabari Terhadap QS Al-Nisa: 128)
Authors: Misran Misran , Maya Sari Maya Sari
Published: October 2019

Penelitian ini bertujuan untuk menjawab dua persoalan pokok, yaitu bagaimana tinjauan hukum Islam terhadap pengabaian kewajiban Istri terhadap suami yang nusyuz dan bagaimana penafsiran Imam Al-Thabari terhadap ayat 128 surat Al-Nisa'. Untuk memperoleh jawaban tersebut penulis menggunakan metode deskriptif kualitatif dengan data primer dan data sekunder. Maka penelitian ini dikategorikan sebagai penelitian kepustakaan (Library Research). Berdasarkan hasil kajian dan penelaahan yang dilakukan dalam literatur fiqh dan Tafsir Al-Thabari, seorang istri tidak boleh mengabaikan kewajibannya terhadap suami meskipun suaminya telah nusyuz karena tidak ada anjuran tersebut dalam Q.S. Al-Nisa' ayat 128 mengenai solusi nusyuz suami, kecuali membuat kesepakatan mengurangi hak dan kewajiban masing-masing sebagai jalan perdamaian. Berdasarkan penafsiran Imam Al-Thabari pada Q.S. Al-Nisa' ayat 128 bahwasanya seorang suami mulai bersikap nusyuz disebabkan oleh beberapa faktor yaitu; istrinya sudah tua, wajahnya tidak mempesona lagi dan istri mandul tidak bisa memberi keturunan. Sehingga suami bersikap acuh dan berpaling darinya serta ingin berpoligami. Pada ayat tersebut Al-Thabari menjelaskan solusi permasalahan seperti ini dengan cara suami-istri membuat persetujuan perdamaian antara keduanya jika seorang istri tidak ingin diceraikan. Namun, jika istri tidak setuju dengan kesepakatan yang dibuat, maka solusi akhirnya ialah bercerai.

Kewenangan Hakim Menerapkan Diskresi dalam Permohonan Dispensasi Nikah (Studi Kasus di Mahkamah Syar’iyah Jantho)
Authors: Syuib M. Syuib , Filzah Nadhilah
Published: October 2019

Penelitian ini bertujuan untuk mencari jawaban dan alasan mengapa hakim dapat mengabulkan dan memberikan dispensasi nikah  kepada pasangan yang belum cukup umur. Untuk memperoleh jawaban tersebut peneliti menggunakan penelitian lapangan (field research) yang didukung dengan data primer berupa wawancara langsung dengan hakim dan panitera permohonan di Mahkamah Syar’iyah Jantho. Hasil penelitian menunjukkan bahwa dasar kewenangan hakim menerapkan diskresi adalah dengan melakukan pemilihan fakta-fakta yang diajukan sehingga dapat dipilih fakta yang relevan dan benar-benar menjadi alasan hukum yang tepat. Dengan begitu, hakim dapat membuat suatu keputusan yang bijaksana yaitu keputusan yang memenuhi unsur keadilan, kepastian, kemanfaatan hukum dan menimbulkan kemaslahatan bagi pasangan tersebut. Temuan lainnya, dasar pertimbangan hakim dalam menerapkan dispensasi nikah dikarenakan khawatir dan takut akan timbulnya fitnah, disebabkan banyak kemudharatan atau dampak negatif yang timbul apabila tidak diberikan dispensasi nikah tersebut.

Consumer segmentation in the German meat market: purchasing habits
Authors: Pirsich Wiebke , Wellner Katharina , Theuvsen Ludwig , Weinrich Ramona
Published: October 2019

Only considering consumers’ store format choice seldom provides sufficient information on their choice of the actual point of purchase for meat: self-service counter or service counter. For retailers, however, it is of crucial importance to know how meat shoppers differ in their store format choice, preferred type of meat packaging and how these differences can be explained. This paper investigates how attitudes and sociodemographics influence consumer segmentation regarding store format choice and preferred meat packaging type in the German meat market. 667 consumers were segmented based on their purchasing frequency, store format choice, and preferred type of meat packaging using cluster analysis. Then, an exploratory factor analysis examined attitudinal factors. Finally, the factors and respondents’ sociodemographics were regressed onto the consumer clusters using multinomial logistic regression. The application of appropriately adapted marketing strategies can help increase patronage in the segments.

O presente artigo busca ilustrar uma passagem notória da história dopensamento econômico, a saber, os fundamentos monetários da crítica de Hayek aoconceito de equilíbrio. Analisam-se as possíveis repercussões, em nível teórico, que talcrítica impôs à percepção do autor austríaco no que se refere ao papel da moeda naeconomia. Isso somente se torna possível pela associação entre moeda e conhecimento,empreendida por Hayek já em sua teoria dos ciclos econômicos. A articulação dessesconceitos – desenvolvidos independentemente ao longo da trajetória acadêmica doaustríaco – permite visualizar, a partir de uma perspectiva diferenciada, a questão daneutralidade da moeda.

Mechanical properties and ageing resistance of slip cast and pressurelessly sintered ZTA - the influence of composition and heat treatment conditions
Authors: Yildirim Nicole , Kern Frank
Published: October 2019

Zirconia toughened alumina (ZTA) ceramics are used in a broad range of
mechanical engineering and biomedical applications due to their excellent
mechanical and tribological properties. In this study it was tried how the
change in stabilizer composition and sintering conditions can be exploited
to selectively modify the mechanical properties and low temperature
degradation resistance of ZTA materials with a typical biomedical grade
composition. It was found that the materials react very sensitively to such
changes. Fully dense materials combining favorable mechanical properties
such as high strength > 800 MPa, fracture toughness > 5.5 MPa?m and LTD
resistance can only be produced in a narrow stabilizer concentration range
between 1.1-1.2 %. Beyond this range materials are either insufficiently
stabilized which results in poor strength and high tendency to LTD, or over
stabilized and no longer susceptible to stress induced phase transformation
and therefore too brittle. Changes in reinforcement mechanisms can be
attributed to changes in microstructure and phase composition caused by
variation of stabilizer content and sintering conditions.

Authors: Tomic Natasa , Vuksanovic Marija , Veljovic Djordje , Djokic Veljko , Marinkovic Aleksandar , Jancic-Heinemann Radmila
Published: October 2019

Two-step synthesis of Fe2O3 particles, performed by precipitation from
iron(III) chloride (FeCl3?6H2O) using ammonium hydroxide in first step and
calcination at 400 and 700?C during 4 h, provided Fe2O3 400?C and Fe2O3
700?C photocatalysts, respectively. The electrospinning process was used to
prepare iron oxide fibers, named Fe2O3 fiber. Morphological and structural
properties of samples were determined by Scanning Electron Microscopy (SEM),
X-ray diffraction (XRD), Fourier Transform Infra-Red (FT-IR) and BET/BJH
analysis. It was found that the ?-Fe2O3 phase (hematite) has shown the
compaction of the structure at 700?C, i.e. lower textural properties.
Hematite particles and fibers are used for bisphenol A (BPA) removal by
photocatalytic decomposition and the enhanced catalytic performance was
found with the use of Fe2O3 400?C particles.

Effects of laser beam lead angle on picosecond laser processing of silicon nitride ceramics
Authors: Wang Heng , Chen Xiaoxiao , Zhang Wenwu
Published: October 2019

Hard and brittle materials are widely used in aerospace, energy, medical, electronics, and other various fields. Multiaxis laser processing is an advanced technology with good development potential and is the key technology for manufacturing complex components from hard and brittle materials. In this work, the authors report the laser machining of silicon nitride ceramics by a five-axis computerized numerical control picosecond laser machine tool, which they use to investigate how laser-beam machining affects the workpiece surface with a zero lead angle, positive lead angle, and negative lead angle. The machining quality, material-removal rate, and energy distribution characteristics for different lead angles are analyzed. The results show that the machined depth and material-removal rate decrease as the absolute value of the lead angle increases. However, the machined surface becomes smoother as the lead angle increases.

Authors: Haryono Yon
Published: October 2019

Performansi yang diharapkan dari proses pemesinan Wire-EDM adalah laju pembuangan material (material removal rate) yang tinggi dan kualitas permukaan (surface integrity) yang baik. Akan tetapi kondisi tersebut  tidak mudah untuk dilakukan karena banyaknya variabel yang mempengaruhi kinerja proses pemesinan Wire-EDM.

            Salah satu upaya untuk mencari solusi dari problem diatas adalah dengan menentukan hubungan antara kinerja proses dengan variabel proses, kemudian dicari kombinasi level variabel proses yang dapat memberikan performansi proses optimum. Penelitian ini dilakukan untuk mengembangkan model dari proses Wire-EDM dengan mengadopsi Response Surface Methodology (RSM). Durasi pulsa, kuat arus, tegangan mekanik  kawat dan kecepatan kawat dipilih sebagai variabel proses, sedangkan laju pembuangan material/material removal rate  (MRR) dan kekasaran permukaan sebagai respon. Proses optimasi dual response dilakukan dengan bantuan paket program aplikasi Quantitative System untuk kasus inequality constraint.

            Hasil yang didapatkan menunjukakan bahwa variabel proses yang dipilih memberikan pengaruh yang signifikan terhadap respon. Laju pembuangan material dan kekasaran permukaan mancapai kondisi optimal secara bersamaan pada kombinasi durasi pulsa 3.83  ms,  kuat arus 2,74 amper, tegangan mekanik kawat 998,93 gr/mm2, dan kecepatan kawat 1419,29 cm/min. Pada seting variabel proses seperti tersebut diatas dihasilkan MRR sebesar 11,48 mm3/min dan kekasaran permukaan 1,86 mm.
El arraigo como factor impeditivo de una expulsión tras la reforma de la LO 1/2015
Authors: Campos Hellín Rodrigo
Published: October 2019

Una de las novedades introducidas en el artículo 89 del Código Penal, tras la reforma operada por la Ley Orgánica 1/2015, de 30 de marzo, por la que se modifica dicho cuerpo legislativo, ha consistido en otorgar rango de obligatoriedad al análisis de las circunstancias personales del penado, especialmente su arraigo, antes de resolver sobre su expulsión. De esta forma, se ha dispensado a dicha circunstancia personal del ostracismo que venía sufriendo con las anteriores reformas del artículo 89 del CP. En este trabajo se analiza en qué consiste ese arraigo, las diferentes modalidades que existen, así como las consecuencias que desplegará dicha regulación teniendo en cuenta que desde la Ley de Extranjería se posibilita la expulsión de extranjeros que hayan cumplido su correspondiente pena de prisión en España.
The Sense in which Ethno-philosophy can Remain Relevant in 21st Century African Philosophy
Authors: Agada Ada
Published: October 2019

Ethno-philosophy, as a philosophical project, has had its fair share of criticism from some professional African philosophers, with Paulin Hountondji as an outstanding critic. Ethno-philosophy is believed to be deficient in criticality and analyticity, which are considered hallmarks of good philosophy anywhere. In this paper I engage Fainos Mangena, a tireless defender of ethno-philosophy, in a critical conversation. In making a case for the continuing relevance of ethno-philosophy, while acknowledging its shortcomings, I argue that the universalist critique of ethno-philosophy has exposed the philosophical poverty of this specific form of thought. I assert that the equation of ethno-philosophy with substantive African philosophy will lead to the emergence of an impoverished African philosophical tradition, notwithstanding the desirability of a unique African philosophy distinguishable from non-African philosophical traditions—in particular the Western philosophical tradition. I point out that Innocent Asouzu and J.O. Chimakonam’s Ibuanyidanda ontology and Ezumezu logical system demonstrate the viability of a philosophical programme that seeks to transcend ethno-philosophy by enriching it with concepts that promote the criticality and analyticity demanded by critics of ethno-philosophy, in a manner conducive to system-building.
Is the Philosophy of the Information Systems Discipline Informed by the Arts and Humanities?
Authors: Kroeze Jan Hendrik
Published: October 2019

The Information Systems discipline (IS) is usually regarded as a social science because it includes research on human-related aspects of these systems. However, a limited number of IS research outputs use approaches that are typical of the traditional arts and humanities. Little recognition has been given to the arts and humanities-informed stream of the IS discipline. This article aims to clarify the subtle distinctions between these scientific constellations and IS’s place in it. It highlights the cluster of arts, humanities and IS in the inter-linked world of scientific disciplines and makes some recommendations to build further on these accomplishments.

The method used in this research is a Completely Randomized Design with Factorial consisting of two factors. First factor consist of n-hexane fraction and ethyl acetate fraction, and second factor consist of six concentrations i.e. 0%; 2%; 4%; 6%; 8%; and 10%. All treatment was conducted on four replications. Medium for testing with subterranean termites was a glass jar containing 10 gram sand and 45 termites worker and 5 termites soldier. Cellulose paper contained extract of n-hexane fraction and ethyl acetate fraction are used as a food source for termites for 21 days. After that the mortality of termites and weight loss of cellulose paper was measure. Result of research showed that concentration 8% and 10% both on extract of n-hexane fraction and ethyl acetate fraction has a high antitermite’s activity with mortality value ≥ 95%. The optimal concentration was achieved on concentration 8% both on extract of n-hexane fraction and ethyl acetate fraction.Keywords : Antitermites, Bark, Coptotermes curvignathus, Rhizophora apiculata, Toxicity
Free-to-Play or Pay-to-Win? Casual, Hardcore, and Hearthstone
Authors: Howard Kenton Taylor
Published: October 2019

“Casual” and “hardcore” are commonly used descriptive terms for games and gamers. While critics have discussed these terms with regards to game design and culture, “free-to-play” games like Blizzard’s Hearthstone add a monetary dimension to such considerations. Players can play such games for free, but success at them often entails purchasing in-game content. These games are sometimes instead derisively referred to as “pay-to-win:” players who spend money win more often. Free-to-play games suggest that casual and hardcore depend on how much money a player spends on the game, in addition to measures like time investment or play practices. I argue that free-to-play games encourage casual players to become more hardcore by spending more money on them in addition to improving their skills at the game, using Hearthstone as a case study to examine the implications of the free-to-play pricing structure on both game design and game players.

Authors: Gao Gege , Shih Patrick C
Published: October 2019

Previous research shows that fewer female players participate in competitive games than male players. However, it has been reported that there are more female than male players in King of Glory (KoG), one of the most popular multiplayer online battle arena (MOBA) games on the mobile platform in China. This study aims to investigate how KoG captures the interest of female players at a higher level than other games. We compared the game design of KoG with League of Legends (LoL), one of the most popular MOBA games on the PC platform. We followed up with a semi-structured interview study with 20 participants about their gameplay experiences on the two different platforms. Our analysis indicates that mobility, sociability, and lower barrier to entry are the main factors that drove female players to participate in KoG.

In recent years, demands for minimal processing and free-synthetic preservatives are
increasing because of growing concern among consumers regarding the safety issues of
additives. Nutmeg (Myristica fragrans Houtt.) has been used as a spice and traditional
medicine in Asian countries. This study aimed to determine the antibacterial activity of
nutmeg extract against foodborne pathogens on raw beef during storage. Nutmeg seeds
were extracted using a maceration method with methanol as a solvent. The extract was
assessed for antibacterial activity against a range of microorganisms using the disc
diffusion assay, minimum inhibitory concentration and minimum bactericidal
concentration. The effect of heat and different pH of the extract on its antibacterial activity
was also conducted to evaluate the stability of the extract. The effects of the extract at
different concentrations on the microbial population of the raw beef during chilled
(4.0±0.2oC) and frozen (-18.0±0.2oC) storage for 21 days were then evaluated. The
nutmeg extract exhibited antimicrobial activity against the range of microorganisms
tested, which was stable at high temperature (80.0±2.0oC) and in the pH range tested (3.0,
6.8, and 11). Furthermore, the extract significantly inhibited microbial growth on raw beef
stored for 21 days in chilled or frozen conditions, indicating that the nutmeg extract has
the potential to be developed as a natural antimicrobial preservative in beef.

Authors: Silva Diego Oliveira , Mourão Matheus Fernandes , Sales Gilvandenys Leite , Silva Bento Duarte
Published: October 2019

O uso de metodologias ativas é uma prática que pode trazer benefícios ao ensino e à aprendizagem de Ciências. No entanto, novas técnicas e recursos pedagógicos são, geralmente, pouco abordados durante os cursos de licenciatura, tornando a existência de cursos de formação continuada tão importantes para o aprimoramento docente. O presente artigo se propõe a documentar a realização de uma oficina sobre metodologias ativas de aprendizagem, ministrada a professores de Ciências em exercício na rede municipal de Fortaleza, bem como a analisar a opinião e os discursos dos mesmos acerca do tema abordado. Durante a oficina foi dada especial atenção à Aprendizagem Baseada em Investigação (ABI), ao uso de Tecnologias Digitais de Informação e Comunicação (TDIC) e à gamificação. Concluiu-se que as técnicas apresentadas durante a oficina foram vistas com bons olhos pelos profissionais da educação e que os mesmos estão inclinados a adotá-las em suas salas de aula.
Plantas medicinais na escola: uma experiência com estudantes dos anos iniciais do Ensino Fundamental
Authors: Dos Santos Bruna Bertoloni , Campos Luciana Maria Lunardi
Published: October 2019

O ensino de Ciências no Ensino Fundamental permite o aprendizado de conceitos básicos, possibilitando ao aluno desenvolver habilidades de investigação, pensamento lógico e ético, garantindo sua inserção à cultura científica. Entretanto, esse ensino nos anos iniciais é descontextualizado, pois utiliza uma linguagem distante da realidade dos alunos, gerando desinteresse. É preciso estabelecer o diálogo entre os saberes populares e científicos. A temática “Plantas Medicinais” mostra-se uma forma de favorecer a aprendizagem, sendo reconhecida a necessidade da valorização das práticas tradicionais/populares. Neste texto, relatamos uma experiência que teve por objetivo elaborar e desenvolver uma proposta de ensino com o objetivo de promover a aprendizagem significativa sobre Plantas medicinais, por meio de atividades práticas diversas, buscando-se favorecer o diálogo entre os saberes científicos e as experiências dos alunos e a construção de novos conhecimentos. A proposta foi desenvolvida com aproximadamente 25 alunos do 5º ano do Ensino Fundamental, com faixa etária de nove a onze anos, de uma escola pública municipal de uma cidade do interior de São Paulo e sua análise mostra que os resultados foram positivos.

Published: October 2019

Este artigo é um recorte de uma pesquisa maior, que foi desenvolvida junto a um programa de doutorado em Educação em Ciências e Matemática. A faceta aqui apresentada está relacionada às possibilidades de a monitoria de Cálculo incentivar a docência e contribuir na formação do futuro professor. A partir de uma leitura crítica do referencial teórico considerado, na sequência avançamos para a constituição do corpus com entrevistas semiestruturadas com monitores e professores responsáveis pelas ações de monitoria. O objetivo geral consiste em compreender como a monitoria de Cálculo pode contribuir na formação do futuro professor para redimensionar os cenários de reprovação e evasão observados. Os resultados indicam que os estudantes procuram se constituir enquanto monitores como forma de entrarem em contato com a docência e também com uma forma de aplicarem as teorias de aprendizagem estudadas em sala de aula. As percepções aqui alcançadas são considerações preliminares e serão agregadas a outros elementos posteriormente.

Published: October 2019

Um novo panorama educacional caracterizado por emergente paradigma de utilização de tecnologias digitais provoca transformações nos costumes da sociedade, reestruturando aspectos metodológicos relativos ao processo de ensino-aprendizagem. Assim, o uso dessas tecnologias viabiliza inúmeras novas atividades na educação, e verifica-se, impacto não somente nas instituições de ensino superior, como também no trabalho do professor. A passagem de um modelo educacional que não contemplava a integração tecnológica para o atual, envolve aspectos que vão além de mudanças organizacionais, culturais, institucionais, de modelos de gestão, de infraestrutura e de processos de educação. O novo cenário de ensino-aprendizagem envolve, sobretudo, mudança de competências e de formação do professor do ensino superior: desenvolvimento acadêmica sólido, experiência profissional e competência pedagógica. Este ensaio discute possíveis relações entre avanços e democratização das tecnologias (nos últimos 20 anos) e alteração do perfil de competências dos professores de ensino superior no Brasil. A partir desta discussão foi possível compreender que os professores devem ser capazes de reconhecer as limitações e o potencial das tecnologias com fins pedagógicos, bem como as melhores técnicas de mediação do conhecimento, reformulando práticas pedagógicas de modo a possibilitar a criação de novas experiências didáticas.
