Abstract Telemedicine is the provision of services by health professionals through the use of information and communication technologies. Its implementation is usually carried out through systems of variable usability. In 2016, Parmanto et al, developed and validated a questionnaire in English that measures its usability and allows to evaluate all factors that influence it. In 2019, we translated, adapted cross-culturally, and published this questionnaire in Spanish. With the aim of transforming it into a reliable and accessible tool, the utility of which is indisputable in the current context, we carried out a research work that allowed its validation and simplification.

Abstract Paper aims The main objective of this work is to integrate a typology of green supply chain management practices with organizational theories. Originality We provide a comprehensive typology of GSCM practices based on empirical evidence and conceptual arguments. Research method Through a systematic review we identified 435 GSCM’s practices that were organized into categories according to their theoretical conception, organizational context and characteristics. Main findings We identified three organizational context dimensions (innovation, performance and management) and proposed a conceptual model of theory-practice-context congruence, to guide the selection of theories for the design of research and analyses of GSCM practices. Implications for theory and practice Our main contribution is the alignment of each category of practices and organizational dimension with the selected theoretical lenses that can help future investigations to deepen the analysis of GSCM practices. Besides the theoretical contributions, we believe this contribution can also achieve practitioners.

Este artigo apresenta o desenho e implementação de uma Nova Abordagem de Ensino (NTA) da ligação química para estudantes do 1º ano do ensino secundário (16-18 anos). Para conceber e testar a proposta foram determinados, depois de tomar em consideração as preconceções dos alunos, vários aspetos-chave a respeito da ligação química. A NTA foi implementada num grupo experimental enquanto o de controlo foi ensinado com a metodologia tradicional. Depois de ser ensinada a ligação química, o mesmo teste abrangente foi aplicado a ambos os grupos e as respostas foram analisadas. Nos resultados, observa-se que as estratégias de ensino utilizadas e a NTA proposta permitem aos alunos desenvolver uma análise de pensamento mais elevado e um conhecimento mais profundo da ligação química, embora ainda alguns aspetos relacionados com o papel da energia na formação da ligação deva ser melhorado na NTA.

Ce rapport montre la conception et la mise en œuvre d'une Nouvelle Approche de l'Enseignement (NTA) de la liaison chimique avec les élèves de 1ère année du secondaire (16-18 ans). Pour concevoir et tester la proposition, plusieurs aspects clés concernant la liaison chimique ont été déterminés après avoir pris en considération les idées préconçues des étudiants. La NTA a été mise en œuvre dans un groupe expérimental tandis que celui de contrôle recevait un enseignement suivant la méthodologie traditionnelle. Après la séquence d’enseignement sur la liaison chimique, le même test complet a été appliqué aux deux groupes et les réponses ont été analysées. Dans les conclusions, il est observé que la NTA proposée et les stratégies d'enseignement utilisées permettent aux élèves de développer une analyse plus approfondie et une connaissance plus profonde de la liaison chimique, bien que certains aspects concernant le rôle de l'énergie dans la formation de liaison doivent encore être améliorées dans la NTA.

This report shows the design and implementation of a New Teaching Approach (NTA) for chemical bonding to 1st year high school students (16-18y). To design and test the proposal several key aspect regarding chemical bonding have been determined after taking into consideration the student preconceptions. The NTA has been implemented in one experimental group while the control one has been taught with traditional methodology. The same comprehensive test has been offered to both groups after being taught chemical bonding, and the answers have been analysed. In the findings it is observed that the proposed NTA and the used teaching strategies let students develop a higher thinking analysis and a deeper knowledge of chemical bonding, although still some aspects regarding the role of energy in bond formation should be improved in NTA.

Abstract: En | Text: En | PDF: En

ABSTRACT This article reports the development and characterization of a nanoemulsion (NE) able to improve the cutaneous penetration of nifedipine. NE with nifedipine was development and characterized, presenting droplet size of 20 nm with low polydispersity index (IP<0.1), spherical shape without aggregation, pH compatible with typical skin levels and stability evaluated by seven months. In the permeation studies, a classical formulation based in an oil/water cream containing nifedipine was used for comparison with NE. Nanoemulsion promoted and improved the retention of nifedipine in the epidermis and dermis in relation to classical formulation. This promoting effect is related to the nanometric size of the droplets of the NE (20 nm), which give him a large superficial area, favoring the contact of the nanocarrier with the skin surface. The NE was efficient in promoting accumulation of nifedipine in the dermis, which is the site of vasodilation action. NE was not irritating according to the primary dermal irritation tests. NE is a promising release system to promote cutaneous penetration of nifedipine and can be used in the future in clinical trials to promote healing of lesions caused by peripheral vascular diseases.

RESUMO Resíduos de Eucalyptus da indústria de papel são resíduos lignocelulósicos potenciais para a produção de bioetanol de segunda geração, como alternativa à produção convencional de culturas de cereais. Estudando o comportamento a 40 ºC de uma celulase comercial (Sunson), a sacarificação de serragem de Eucalyiptus foi conduzida em duas condições de pH. A fim de avaliar a produção de bioetanol a partir de madeira de Eucalyptus foi realizada uma estratégia que combina a sacarificação, sacarificação e fermentação simultâneas a 40 ºC, com uma Saccharomyces cerevisiae tolerante à temperatura e com diferentes concentrações de substrato e de inóculo, e diferentes fontes de azoto. Em seguida, o processo foi realizado em condições ótimas com Saccharomyces cerevisiae M522 e SacSV-10. A sacarificação produziu mais glicose livre em pH 5, atingindo um máximo de 1,5 g/L. Resultados promissores foram obtidos com 500 mg/L de sulfato de amónio como fonte de azoto e 10 % v/v de inoculo, a uma concentração de 106 ufc/mL. A levedura SacSV-10 não foi inibida por fenóis presentes no meio de cultura, utilizando uma concentração de madeira de 10 g / l, mas quando a concentração de sólidos aumentou, o desempenho bioprocesso foi comprometido. Quando o processo é realizado em condições ótimas, a produção de bioetanol expressada como a percentagem de conversão de celulose para etanol foi de 71,5 % e 73,6 % para as estirpes mutantes e M522 respectivamente. As propriedades concedidas à tensão estudou, vai agregar valor, criando novos desafios para as empresas nacionais que se dedicam à produção e venda de insumos para a indústria do bioetanol

ABSTRACT Eucalyptus spp. residues of paper industry are a potential lignocellulosic raw material for production of second-generation bioethanol as an alternative to conventional production from cereal crops. Studying the behavior at 40 ºC of a commercial cellulase (Sunson), Eucalyptus sawdust saccharification was carried out under two pH conditions. With the aim to evaluate the bioethanol production from Eucalyptus wood, a strategy combining saccharification and Simultaneous Saccharification and Fermentation (SSF) was undertaken at 40 ºC with a thermotolerant Saccharomyces cerevisiae with different substrate and inoculum concentrations, and different nitrogen sources. At last, the process was carried out in optimal conditions with Saccharomyces cerevisiae M522 and SacSV-10. Saccharification produced more free glucose at pH 5, reaching a maximum of 1.5 g/L. Encouraging results were obtained with 500 mg/L of ammonium sulphate as a nitrogen source and 10 % v/v initial inoculum at 106 cfu/mL concentration. Yeast SacSV-10 was not inhibited by phenols present in the culture media using a wood concentration of 10 g/L, but when the solids concentration was increased, the bioprocess yield was compromised. When the process was carried out in optimal conditions the bioethanol production, expressed as the conversion percentage of cellulose to ethanol, was 71.5 % and 73.6 % for M522 and the mutant strain respectively. The studied properties of the mutant strain provide added value to it, which pose new challenges to national companies dedicated to the production and sale of inputs for bioethanol industry.

OBJETIVO: Avaliar a associação entre a prevalência de má oclusão em crianças aos 12 anos de idade com variáveis individuais e contextuais. MÉTODOS: Foi realizado um estudo transversal analítico com dados da Pesquisa Nacional de Saúde Bucal – SBBrasil 2010. O desfecho estudado foi a má oclusão, categorizada em ausente, definida, severa e muito severa. As variáveis independentes foram classificadas em individuais e contextuais. Os dados foram analisados por meio de modelo multinível, considerando nível de 5% de significância. RESULTADOS: A prevalência de má oclusão severa e muito severa nas crianças com 12 anos de idade não diferiu entre as regiões brasileiras, mas sim entre as cidades (p < 0,001). Crianças do sexo masculino (p = 0,033), de menor renda (p = 0,051), que consultaram o dentista (p = 0,009), com menor satisfação com a boca e os dentes (p < 0,001) e com vergonha de sorrir (p < 0,001) apresentaram má oclusão de maior gravidade. As características das cidades também afetaram a gravidade da má oclusão; cidades com mais famílias com benefício social por 1.000 habitantes, com menores notas do índice de desempenho do sistema de saúde e menor renda per capita foram estatisticamente associadas com a má oclusão. CONCLUSÕES: Associações significativas entre a presença e gravidade da má oclusão foram observadas em nível individual e contextual.

OBJECTIVE: To assess the association between the prevalence of malocclusion in Brazilian 12 years-olds with individual and contextual variables. METHODS: A cross-sectional, analytical study was conducted with data from the Brazilian Oral Health Survey – SBBrazil 2010. The outcome studied was malocclusion, categorized as absent, set, severe and very severe. The independent variables were classified as individual and contextual. Data were analyzed using a multilevel model with a 5% significance level. RESULTS: It was found that the prevalence of severe and very severe malocclusion in 12-year-olds did not differ between the Brazilian regions, although variation between the cities was significant (p < 0.001). Male children (p = 0.033), those on lower income (p = 0.051), those who had visited a dentist (p = 0.009), with lower levels of satisfaction with mouth and teeth (p < 0.001) and embarrassed to smile (p < 0.001) had more severe malocclusion. The characteristics of the cities also affected the severity of malocclusion; cities with more families on social benefits per 1,000 inhabitants, with lower scores on the health care system performance index and lower gross domestic product per capita were significantly associated with malocclusion. CONCLUSION: Significant associations between the presence and severity of malocclusion were observed at the individual and contextual level.
