Vegetable oils obtained from different plants are known for their beneficial effects on prophylaxis and supportive treatment of a great deal of inflammatory-mediated conditions. Their wide range of saturated and unsaturated fatty acids, and the presence of other ingredients (e.g., tocopherols, chlorophylls), provide them with anti-inflammatory, antioxidant and anticancer properties, which are worth being exploited. In this study, we have carried out the spectrofluorometric analysis of selected vegetable oils, namely apricot (Prunus armeniaca) kernel oil; blueberry (Vaccinium spp.) seed oil; argan (Argania spinosa) nut oil; kiwi (Actinidia deliciosa) seed oil; grape (Vitis vinifera) seed oil; evening primrose (Oenothera biennis) oil and meadowfoam (Limnanthes alba) seed oil, with the purpose to detect their fluorescent ingredients for further identification and bioactivity comparison. The obtained two- (2D) and three-dimensional (3D) emission spectra offered a complete description of the fluorescent components of the mixture and revealed different features for studied oils.

Published: November 2020

Thiazinanes and its isomeric forms represent one of the most important heterocyclic compounds, and their derivatives represented a highly potent drug in disease treatment such as, 1,1-dioxido-1,2-thiazinan-1,6-naphthyridine, which has been shown to have anti-HIV activity by a mechanism that should work as anti-AIDS treatment, while (Z)-methyl 3-(naphthalen-1-ylimino)- 2-thia-4-azaspiro[5 5]undecane-4-carbodithioate showed analgesic activity, cephradine was used as antibiotic and chlormezanone was utilized as anticoagulants. All publications were interested in the chemistry of thiazine (partially or fully unsaturated heterocyclic six-membered ring containing nitrogen and sulfur), but no one was dealing with thiazinane itself which encouraged us to shed new light on these interesting heterocycles. This review was focused on the synthetic approaches of thiazinane derivatives and their chemical reactivity.

Authors: Yuan Siqi , Yong Xihao , Zhao Ting , Li Yuan , Liu Jun
Published: November 2020

Pulcherriminic acid is a cyclic dipeptide found mainly in Bacillus and yeast. Due to the ability of pulcherriminic acid to chelate Fe3+ to produce reddish brown pulcherrimin, microorganisms capable of synthesizing pulcherriminic acid compete with other microorganisms for environmental iron ions to achieve bacteriostatic effects. Therefore, studying the biosynthetic pathway and their enzymatic catalysis, gene regulation in the process of synthesis of pulcherriminic acid in Bacillus can facilitate the industrial production, and promote the wide application in food, agriculture and medicine industries. After initially discussing, this review summarizes current research on the synthesis of pulcherriminic acid by Bacillus, which includes the crystallization of key enzymes, molecular catalytic mechanisms, regulation of synthetic pathways, and methods to improve efficiency in synthesizing pulcherriminic acid and its precursors. Finally, possible applications of pulcherriminic acid in the fermented food, such as Chinese Baijiu, applying combinatorial biosynthesis will be summarized.
Carbonyl Compounds Containing Formaldehyde Produced from the Heated Mouthpiece of Tobacco Sticks for Heated Tobacco Products
Authors: Kim Yong-Hyun , An Young-Ji , Shin Jae-Won
Published: November 2020

Diverse harmful compounds can be emitted during the heating of tobacco sticks for heated tobacco products (HTPs). In this study, the generation of harmful compounds from the filter, instead of tobacco in tobacco sticks, was confirmed. The heat of a heated tobacco product device can be transferred to the tobacco stick filter, resulting in the generation of harmful compounds from the heated filter. Since the heating materials (tobacco consumable) of the tobacco sticks evaluated in this study were different depending on the brand, the harmful compounds emitted from the heated tobacco stick filters were examined by focusing on the carbonyl compounds, using three different tobacco stick parts. Acetaldehyde and propionaldehyde exhibited the highest concentrations in HTP aerosols produced by heating the tobacco consumable (conventional case) (63.5 ± 18.4 µg/stick and 1.71 ± 0.123 µg/stick, respectively). The aerosols produced by heating tobacco stick filters had higher formaldehyde and acrolein concentrations (0.945 ± 0.214 µg/stick and 0.519 ± 0.379 µg/stick) than the aerosols generated from heated tobacco consumable (0.641 ± 0.092 µg/stick and 0.220 ± 0.102 µg/stick). As such, formaldehyde and acrolein were produced by heating small parts of the mouthpiece of a tobacco stick, regardless of the heated tobacco product brand. In addition, acetone was only detected in the aerosols generated from heated filters (0.580 ± 0.305 µg/stick). Thus, safety evaluations of heated tobacco products should include considerations of the harmful compounds generated by heating tobacco stick mouthpieces for heated tobacco products in addition to those found in heated tobacco product aerosols.

Published: November 2020

This study aimed to investigate the chemical composition of the leaf essential oil from Ivoirian Isolona dewevrei. A combination of chromatographic and spectroscopic techniques (GC(RI), GC-MS and 13C-NMR) was used to analyze two oil samples (S1 and S2). Detailed analysis by repetitive column chromatography (CC) of essential oil sample S2 was performed, leading to the isolation of four compounds. Their structures were elucidated by QTOF-MS, 1D and 2D-NMR as (10βH)-1β,8β-oxido-cadin-4-ene (38), 4-methylene-(7αH)-germacra-1(10),5-dien-8β-ol (cis-germacrene D-8-ol) (52), 4-methylene-(7αH)-germacra-1(10),5-dien-8α-ol (trans-germacrene D-8-ol) (53) and cadina-1(10),4-dien-8β-ol (56). Compounds 38, 52 and 53 are new, whereas NMR data of 56 are reported for the first time. Lastly, 57 constituents accounting for 95.5% (S1) and 97.1% (S2) of the whole compositions were identified. Samples S1 and S2 were dominated by germacrene D (23.6 and 20.5%, respectively), followed by germacrene D-8-one (8.9 and 8.7%), (10βH)-1β,8β-oxido-cadin-4-ene (7.3 and 8.7), 4-methylene-(7αH)-germacra-1(10),5-dien-8β-ol (7.8 and 7.4%) and cadina-1(10),4-dien-8β-ol (7.6 and 7.2%). Leaves from I. dewevrei produced sesquiterpene-rich essential oil with an original chemical composition, involving various compounds reported for the first time among the main components. Integrated analysis by GC(RI), GC-MS and 13C-NMR appeared fruitful for the knowledge of such a complex essential oil.

Published: November 2020

The cationic Pt complex (Pt(NC6H4-C6H4N-(CH2)10-O(C6H3-3,5-(OMe)2)(MeN-(CH2CH2NMe2)2))+ was prepared by the reaction of alkylbipyridinium ligand with a nitrateplatinum(II) complex. Mixing the complex and α- and β-cyclodextrins in aqueous media produced the corresponding [2]rotaxanes with 1:1 stoichiometry. γ-Cyclodextrin and the Pt complex formed a rotaxane having components in a 1:1 or 2:1 molar ratio. The results of mass and nuclear magnetic resonance (NMR) measurements confirmed the rotaxane structures of the Pt complexes. Transmission electron microscopy (TEM) and atomic force microscope (AFM) analyses revealed the formation of micelles or vesicles. The addition of NaBH4 to the rotaxanes in aqueous media formed Pt nanoparticles with diameters of 1.3–2.8 nm, as characterized by TEM. The aggregated size of the nanoparticles formed from the rotaxane did not change even at 70 °C, and they showed higher thermal stability than those obtained from the reduction of the cyclodextrin-free Pt complex.
Saffron: Chemical Composition and Neuroprotective Activity
Authors: Maggi Maria Anna , Bisti Silvia , Picco Cristiana
Published: November 2020

Crocus sativus L. belongs to the Iridaceae family and it is commonly known as saffron. The different cultures together with the geoclimatic characteristics of the territory determine a different chemical composition that characterizes the final product. This is why a complete knowledge of this product is fundamental, from which more than 150 chemical compounds have been extracted from, but only about one third of them have been identified. The chemical composition of saffron has been studied in relation to its efficacy in coping with neurodegenerative retinal diseases. Accordingly, experimental results provide evidence of a strict correlation between chemical composition and neuroprotective capacity. We found that saffron’s ability to cope with retinal neurodegeneration is related to: (1) the presence of specific crocins and (2) the contribution of other saffron components. We summarize previous evidence and provide original data showing that results obtained both “in vivo” and “in vitro” lead to the same conclusion.
Gastroprotective Effects of Inulae Flos on HCl/Ethanol-Induced Gastric Ulcers in Rats
Authors: Kim Young-Sik , Lee Ji Hyeon , Song Jungbin , Kim Hocheol
Published: November 2020

Inulae Flos, the flower of Inula britannica L., is used as a dietary supplement, beverage, and medicine in East Asia. In this study, we evaluated the gastroprotective effects of Inulae Flos extract (IFE) against gastric mucosal lesions induced by hydrochloric acid (HCl)/ethanol in rats and explored its potential mechanisms by measuring antioxidant enzyme activity, mucus secretion, and prostaglandin E2 (PGE2) levels. Pretreatment with IFE at doses of 100 and 300 mg/kg significantly inhibited gastric lesions in HCl/ethanol-treated rats. IFE increased the activities of superoxide dismutase and catalase and the levels of glutathione and PGE2 in gastric tissues. The administration of IFE also significantly increased the gastric wall mucus contents in HCl/ethanol-induced gastric lesions. These findings suggest that IFE has gastroprotective effects against HCl/ethanol-induced gastric lesions and exerts these effects through increased antioxidant levels and gastric mucus secretion. Inulae Flos may be a promising agent for the prevention and treatment of gastritis and gastric ulcers.
Alpha-Synuclein—Nanoparticle Interactions: Understanding, Controlling and Exploiting Conformational Plasticity
Authors: D’Onofrio Mariapina , Munari Francesca , Assfalg Michael
Published: November 2020

Alpha-synuclein (αS) is an extensively studied protein due to its involvement in a group of neurodegenerative disorders, including Parkinson′s disease, and its documented ability to undergo aberrant self-aggregation resulting in the formation of amyloid-like fibrils. In dilute solution, the protein is intrinsically disordered but can adopt multiple alternative conformations under given conditions, such as upon adsorption to nanoscale surfaces. The study of αS-nanoparticle interactions allows us to better understand the behavior of the protein and provides the basis for developing systems capable of mitigating the formation of toxic aggregates as well as for designing hybrid nanomaterials with novel functionalities for applications in various research areas. In this review, we summarize current progress on αS-nanoparticle interactions with an emphasis on the conformational plasticity of the biomolecule.

Published: November 2020

Aroma plays an important role in designing innovative functional foods. This study aimed to study the influence of incorporating herbs from the Lamiaceae family (sage, mint, rosemary, oregano, thyme) on aroma compound formation and sensory properties in oat-buckwheat products. DPPH, FRAP and PCL have been used to describe possible antioxidant activity changes and reduce power of cookies after Lamiaceae Lindl. addition. The volatiles analysis by HS-SPME-GC/MS, has shown that Lamiaceae addition significantly influences the volatiles composition (29 molecules) with a predominance of molecules with a positive sensorial impression. Cookies elaborated with herbs were characterized by a greater share of monoterpenes (e.g., limonene, eucalyptol), in the volatile profile than in control cookies. These compounds’ occurrence was closely correlated with the appearance of herbal odor and taste among sensory attributes in cookies with herbs addition. In contrast, a decrease of negative oil aroma and the bitter aftertaste was noted by a sensory panel. Moreover, in cookies of mint and rosemary, hexanal share decreased about 13 and 9.7-times, respectively. Considering all presented experiments, rosemary addition was the most effective in forming a positive aroma profile with high sensory acceptance and increased functional properties.

Published: November 2020

The two aims of this study were (1) designing and developing an affordable visual reaction system for badminton training that monitors and provides instant feedback on agility; and (2) to measure and improve the footwork and movement of badminton players and output useful reference data. Ten junior high school badminton players were invited to serve as the subjects of this study. They participated in a three-week (nine sessions) training program. Training was primarily in the form of fixed or random footwork drills. Timed tests were performed before and after each session to measure the players’ agility in performing six-point and four-point footwork drills. The results were compared to the training effects calculated using dependent-sample t-tests. In addition, the long-term durability and functionality of the training system were tested. The training system was able to maintain stable and reliable training and evaluation operations for extended periods. Results showed significant improvements in the visual reaction time (p = 0.003) and agility (p = 0.001) of players. The proposed training system is an affordable option for training and monitoring, evaluating, and recording training performance. It can accurately record movement and response times and simulate competitive environments.

Authors: Kim Imhyeon , Kim Jinsoo , Kang Jeongyeon
Published: November 2020

This study aims to investigate the relationship between company reputation and the implied cost of capital in Korean companies from 2003 to 2016, based on research by Cao et al. (2015). In addition, we would like to examine the effect of tax avoidance. Company reputation increases corporate sustainability and enables sustainable management. In this study, Brandstock Top Index (BSTI), which represents Korea’s top 100 brands, was used as an interest variable representing company reputation. To examine the relationship between company reputation and implied cost of capital, the multiple linear regression analysis was conducted using various measures of implied cost of capital as a dependent variable. As a result of empirical analysis, company reputation and implied cost of capital showed a significant negative relationship. The higher the company’s reputation, the less information asymmetry in the stock market, indicating that the implied cost of capital decreases. A significant negative relationship between company reputation and implied cost of capital was not found in a group that was aggressive in tax avoidance. The contributions of this study are as follows. First, we presented the empirical result that company reputation and implied cost of capital were negatively related in Korea. It showed empirically the importance of company reputation in the Korean stock market. Second, in addition to the relationship between company reputation and implied cost of capital, prior research was expanded considering tax avoidance.

Published: November 2020

Este estudo se conformou a partir de uma investigação que teve como objetivo analisar a jornada de trabalho de professores dos anos iniciais da Rede Municipal de Rio Branco e suas possíveis implicações ao trabalho docente. Foram sujeitos do estudo cinquenta professores distribuídos em oito escolas, que responderam a um questionário autoaplicável. Constatou-se que os docentes possuem contratos de trabalho com jornada compatível com a estabelecida no Plano de Cargos, Carreira e Remuneração dos servidores do Magistério de Rio Branco de vinte e cinco horas semanais. No entanto, ao longo da pesquisa, evidencia-se o processo de intensificação da jornada, motivada dentro outros fatores pelo prolongamento da jornada, ocasionada pelo excesso de demandas ligadas a docência, pelo acúmulo de contratos e pelo número de alunos nas turmas.
O paradoxo entre as Diretrizes Curriculares do Curso de Pedagogia e a prática profissional em gestão escolar
Authors: Monteiro Rui Anderson Costa
Published: November 2020

As preocupações com a formação de professores, bem como o processo de gestão da educação básica não é objeto recente de discussão, ganhando destaque a partir da década de 1990. Em meio à crise histórica de identidade do Curso de Pedagogia e a influência constante do Estado na regulação no ensino superior e da educação básica, buscou-se fazer resgate histórico, discutindo o papel do diretor de escola e contextualizando a normativa para a sua formação. Pautamos a pesquisa na análise documental e qualitativa fundamentada nas categorias: história, diretrizes curriculares, formação e gestão. Na tentativa de legitimar o papel do pedagogo, vislumbramos a formação acelerada pautada em diretrizes que preconizam egresso do ensino superior com muitas atribuições, mas que, diante da complexidade do papel do gestor escolar, não adquire competências suficientes no processo de formação inicial, o que torna incoerente a exigência primária desta habilitação ao cargo de diretor de escola.

Published: November 2020

O som, seja pela sua presença ou pela sua ausência, influência e altera a percepção que se tem de um espaço, sendo um qualificador deste espaço e contribuindo para transformá-lo ou não em um lugar. Ainda que exista um domínio da visão sob os demais sentidos, os sons, os odores e as sensações térmicas, mesmo que efêmeros e dinâmicos, não podem ser desconsiderados, haja vista que são responsáveis pela construção das ambiências e consequente construção sensível dos espaços. A Paisagem Sonora ("soundscape"), propõe o estudo do ambiente acústico de maneira sistematizada e contextualizada. Uma paisagem sonora é a extensão do território que se pode escutar, abrangendo todos os sons produzidos no ambiente, sendo também sempre uma criação cultural. O presente projeto de pesquisa propõe um estudo da Paisagem Sonora de Juiz de Fora, mais especificadamente da região do centro urbano da cidade, compreendida no recorte deste estudo como o “Triângulo Central”, espaço que detém parte significativa da história da cidade, apresentando diversos usos e formatações ao longo do tempo. O Triângulo Central representa uma parcela do território urbano dos mais importantes como portador de memória, tratando-se de um dos lugares mais pertinentes para a compreensão do desenvolvimento de Juiz de Fora. Foi proposto também um recorte temporal, datado entre as décadas de 1880 e 1940. Este recorte espacial-temporal justifica-se pela própria relevância histórico-cultural que apresenta para Juiz de Fora. Porém, tendo em vista a densidade dos resultados obtidos até o momento, abordoe-se a primeira década deste recorte, compreendida de 1880 a 1890. O objetivo geral desta pesquisa é resgatar parte da memória sonora da cidade de Juiz de Fora, categorizando os sons destacados como relevantes (histórica e/ou culturalmente) e identificando a transformação da paisagem sonora em meio às transformações dos espaços urbanos. Configura-se como tendo uma abordagem qualitativa, pois não se baseia na representatividade numérica, isto é, os dados são considerados na análise de acordo com qualidade do material coletado, sendo considerados os registros sonoros mais destacadamente relevantes para a pesquisa. Assim, ainda que sejam apresentados dados numéricos neste estudo, estes têm relevância como respaldo à análise qualitativa. Caracteriza-se como uma pesquisa documental, uma vez que trabalha com fontes primárias (jornais) que ainda não receberam um tratamento analítico com o enfoque desta pesquisa. A partir da pesquisa proposta e seus desdobramentos, gerou-se um mapa gráfico-sonoro, com indicativo de sons coletados em cada área, servindo como registro histórico-cultural das percepções sonoras no centro de Juiz de Fora, criando-se um registro da paisagem sonora em tal espaço-tempo.

Authors: Sarmiento Érica
Published: November 2020

El artículo tiene como objetivo contribuir, de manera introductoria, a los estudios de las asociaciones gallegas de alcance microterritorial en Río de Janeiro, utilizando cono fuente principal la correspondencia entre el Consulado Español y las asociaciones españolas/gallegas ubicadas en Río de Janeiro, en la década de 1930, período correspondiente al de la Guerra Civil española y al gobierno de Getúlio Vargas, con el inicio del Estado Novo, en 1937. A partir de la interpretación de las fuentes obtenidas en el Archivo General de la Administración, del Ministerio de Asuntos Exteriores, fue posible formular argumentos sobre algunas de las microasociaciones pertenecientes a la comunidad gallega de las primeras décadas del siglo XX y que supuestamente desaparecieron en una etapa temprana. Investigamos la funcionalidad de algunas de las sociedades microterritoriales, la importancia de la escala en los estudios migratorios, la percepción de las redes sociales, así como las lagunas evidenciadas por la historiografía sobre las sociedades gallegas y españolas en general.
Estorbos a un regidor advenedizo: justicia, facciones y conflicto urbano en la España del siglo XVII
Authors: Mantecón Movellán Tomás A.
Published: November 2020

Este artículo analiza la documentación que produjo la causa criminal contra un edil de la localidad granadina de Motril en la primera mitad del siglo XVII. El regidor Pérez Merino llegó a la villa en un contexto de recepción de inmigrantes en una comunidad urbana afectada de forma importante por la expulsión de los moriscos. Pérez, en ese contexto, se construyó un espacio de poder dentro del gobierno local. La fricción dentro de la élite gobernante acabó por generar una demanda criminal y un costoso expediente judicial que se resolvió finalmente por medio de la gracia del rey. El análisis de esta documentación permite explicar los rasgos del arquetipo de mal gobernante urbano; además, sopesar las distancias entre los discursos y las pruebas sobre los hechos y, finalmente, identificar las implicaciones, instrumentos y prácticas de la justicia para reconstruir la paz pública en la España del siglo XVII.

The outbreak of a novel coronavirus (SARS-CoV-2) and associated COVID-19 disease in late December 2019 has led to a global pandemic, spreading very quickly and causing a more than 500,000 deaths in less than six monhs of the ourbreak. The incidence differs by country and depends on many agents, such as population density, demography, the amount of testing people and reporting, and actions of mitigation strategies, provisions of sanitary and education of the society. In this article, we presented the current studies about the epidemiology of COVID-19, including the transmission routes of the SARS-CoV-2, the incubation period, the reproduction number (R0), the case fatality risks (CFR), comorbidities and measures prevention against COVID-19. We searched the articles in the main database (PubMed/Medline, Elsevier Science Direct, Scopus, Isi Web of Science, Embase, Exerpta Medica, UptoDate, Lilacs, Novel Coronavirus Resource Directory from Elsevier), in the high-impact international scientific Journals (Scimago Journal and Country Rank - SJR - and Journal Citation Reports - JCR), such as The Lancet, Science, Nature, The New England Journal of Medicine, Physiological Reviews, Journal of the American Medical Association, Plos One, Journal of Clinical Investigation, and in the data from Center for Disease Control (CDC), National Institutes of Health (NIH), National Institute of Allergy and Infectious Diseases (NIAID) and World Health Organization (WHO). We prior selected meta-analysis, systematic reviews, article reviews and original articles in this order. We reviewed 235 articles and used 131 from March to June 2020, using the terms coronavirus, SARS-CoV-2, novel coronavirus, Wuhan coronavirus, severe acute respiratory syndrome, 2019-nCoV, 2019 novel coronavirus, n-CoV-2, covid, n-Sars-2, COVID-19, corona virus, coronaviruses, epodemiology of COVID-19, risk factors, viral spreading, transmissions, routes, animals incubation, period, RO, CFR, comorbidities, prevention, with the tools MeSH (Medical Subject Headings), AND, OR, and characters [,“,; /., to ensure the best review topics. We concluded that the epidemiological data is very important to know the transmission risks rate, purpose public political policies of mitigating the disease, protect the vulnerable population. Also, it is important reconsider the legislation about wild animals, the potential intermediate host(s) of various viruses, as well as the conditions of live for animals for human comsuption to prevent future outbreaks.

Türkiye Bina Deprem Yönetmeliği 2018 (TBDY, 2018)’de geleneksel donatılmış betonarme bağ kirişleri için öngörülen şekil değiştirme esaslı hasar sınırları analitik olarak incelenmiştir. Geleneksel donatılmış betonarme bağ kirişlerinin çekme ve basınç donatısı oranı, enine donatı çapı ve aralığı sabit tutulmuş net açıklık / derinlik oranı ve beton basınç dayanımını değiştirilerek SAP 2000 programı ile moment-eğrilik değerleri hesaplanmıştır. Bu çalışmada; gerçek malzeme davranışları esas alınmıştır. Elde edilen momenti-eğrilik ilişkilerinden betonarme bağ kirişlerinin elastik ötesi davranışları incelenmiştir. Geleneksel donatılmış betonarme bağ kirişi modelleri için moment-eğrilik ilişkilerinden elde edilen veriler kullanılarak TBDY, (2018)’de verilen hasar sınır değerleri betonarme bağ kiriş modelleri için hesaplanmıştır. Şekil değiştirme değerleri TBDY (2018)’de tanımlanmış olan göçmenin önlenmesi (GÖ), kontrollü hasar (KH) ve sınırlı hasar (SH) performans seviyeleri için hesaplanmıştır. Geleneksel donatılmış betonarme bağ kirişleri için üç ayrı hasar sınırı ve bu hasar sınırlarına karşı gelen birim şekil değiştirme değerleri incelenmiştir. Geleneksel donatılmış betonarme bağ kirişlerde farklı performans düzeyi için beton ve donatı çeliği birim şekil değiştirmeleri ve plastik dönmeleri hesaplanarak performans düzeyleri araştırılmıştır. GÖ ve KH performans düzeyleri için plastik dönmelerin hasar sınırları; akma eğriliği, kopma eğriliği, plastik mafsal uzunluğu, kesme açıklığı ve boyuna donatı çapının fonksiyonu olarak tanımlanmıştır. Bu çalışmada; geleneksel donatılmış bağ kirişlerinin beton basınç dayanımının akma momentine (M_y), GÖ ve KH performans düzeyleri için plastik dönme sınırlarına (θ_P^((KH)) ve θ_P^((GÖ))) etkili olduğu gözlemlenmiştir. Net açıklık derinlik oranın (l_n/h) artırılması; geleneksel donatılmış betonarme bağ kirişlerininGÖ ve KH performans düzeyleri için izin verilen plastik dönme sınırlarına (θ_P^((KH)) ve θ_P^((GÖ))) ve akma durumu için yer değiştirmiş eksen dönmesi üzerine (θ_y) etkili olduğunu ispatlanmıştır.

Sobre experiências interartes e educação
Authors: Macieira Cássia
Published: November 2020

Durante 22 anos o Grupo Giramundo Teatro de Bonecos firmou um convênio com a UFMG, promovendo, entre outros, convívios estéticos entre alunos e professores. Maria do Carmo Vivacqua Martins (Madu) e Terezinha Veloso, cofundadoras do grupo, atuaram como professoras-artistas na Escola de Belas Artes/UFMG, mantendo, concomitantemente, produções artísticas individuais e coletivas. A partir da imagem disparadora de um(a) boneco(a) e uma pintura como agenciadores da interdisciplinaridade, este artigo visa compreender a presença do(a) boneco(a) sob a perspectiva dos estudos interartes e da Educação e, a práxis-poiesis de ambas as professoras-artistas, mediante uma investigação qualitativa (percepções e construção social de sentido) por meio da A/R/Tografia: metodologia poética que evidencia a identidade dos artistas.
poética de dispositivos artísticos com aparatos computacionais
Authors: Souza Leonardo Silva
Published: November 2020

Este artigo trata de experimentos artísticos com aparatos computacionais, apresentando a ideia de uma Poética de Heterogêneses. Neste âmbito, propomos o entendimento de modos de composição que lidam com materiais e formas de pensamento que são tratados de formas distintas pelos campos da Arte, Ciência e Tecnologia. O texto correlaciona estudos de cunho técnológico, como os de Kowalski(1970), Robinson(2008) e Fuller(2008), aos de reflexões contemporâneas sobre Arte, como os de Bishop(2012), Broeckmann(1997), Deleuze(1992;2005), Duguet(1988) e Goffey(2009) e, a partir desta correlação, desloca conceitos como Aparelho, Aparato, Algoritmo, Composição e Dispositivo, reorientando-os a fim de erguer as bases de uma poética que se coloca entre Arte, Ciência e Tecnologia.
PERSPECTIVES ON ART EDUCATION AS AN INTERDISCIPLINARY PRACTICE
Authors: Worrall Peter
Published: November 2020

This paper presents a sample of art education experiences, that I have been privileged to        explore over 40 years. This has involved developing rationales that were required to apply to the new technologies emerging in art education in 1985.  My research in this area included media workshops in England, Europe and South America.

The new ‘cultures’ of communication and new technologies in 21st century continue to expand our understanding of both the universe and the diverse eco systems on our planet. We live in the age of interdisciplinary practice which provides new opportunities for artists to collaborate with scientists and mathematicians.
