A organização pedagógica das universidades sénior do distrito de Évora

O objetivo principal deste estudo consiste em “Conhecer e caracterizar os modelos pedagógicos do ensino não formal e informal nas Universidades Sénior do distrito de Évora”. Para concretizar este objetivo, foram selecionadas três Universidades Sénior do distrito de Évora: Universidade Sénior de Évora, Universidade Sénior de Reguengos de Monsaraz e a Universidade Popular Túlio Espanca-Pólo de Viana do Alentejo, para conhecer a respetiva oferta formativa e caracterizar o padrão curricular da cada instituição. Por último, pretendeu-se caraterizar o público-alvo e destinatários desta Oferta. Este ensino não formal é desenvolvido por professores que dedicam o tempo a elaborar projetos e atividades nestas Universidades Sénior, contribuindo assim para a aprendizagem nas diversas áreas, como as artes e humanidades. A organização pedagógica destas instituições apresenta inúmeras diferenças na estrutura interna e existe uma discrepância considerável, no número professores e alunos que frequentam estas US. A forma como as US estão integradas na comunidade, os projetos e atividades que desenvolvem, são de certa forma o modelo da sua evolução e o progresso; ### ABSTRACT: THE PEDAGOGICAL ORGANIZATION OF SENIOR UNIVERSITIES IN ÉVORA'S DISTRICT The main purpose of this study will be to “Know and describe the pedagogical models of formal and non-formal education in Senior Universities from Évora’s district”. To fulfill this purpose we selected three Senior Universities of the district, such as Senior University of Évora, Senior University of Reguengos de Monsaraz and the Popular Tulio Espanca University - Campus of Viana do Alentejo. In this way it will be possible to know each educational offer and to describe the curricular pattern of each institution. It will also allow us to describe the target public of the Senior Universities in Évora’s district . This non-formal education is developed by teachers who dedicate their time to developing projects in these Senior Universities, making a contribution to learning several areas, such as arts and social sciences. The pedagogical organization of these institutions shows us that there are several differences between them and that there is a considerable discrepancy in the number of teachers and students that come to such institutions. The way in which they are integrated in the community, their projects and activities, are, in a way, the model of their evolution and progresso.

Propolis components accountable for bactericidal accomplishment and antibiofilm activity

This study aimed at evaluating antimicrobial and antibiofilm activity of phenolic compounds present in propolis ethanol extracts (PEE). Seventy per cent ethanol extracts from seven types of propolis, one Green, two Red and four Brown collected in four Brazilian States were prepared and total phenolics, flavonoids, tannins and anthocyanins were assessed by high-performance liquid chromatography (HPLC). Minimum bactericidal concentration (MBC) and inhibitor effect on Staphylococcus aureus biofilm formation and capacity to disrupt established biofilms were assessed towards eight S. aureus isolates from milk of small ruminants with mastitis, one methicillin-resistant S. aureus (MRSA) and S. aureus ATCC 25923. To evaluate different propolis components accountability for bactericidal accomplishment and antibiofilm activity, the results were analysed by the non-parametric Spearman coefficient. Results of phenolic compounds were 216,21 to 312,08 gallic acid milligram equivalent per extract gram (mg EGA/g) of total phenolics, 55,08 to 140,6 quercetin milligram equivalent per extract gram (mg EQ/g) of flavonoids, 118,51 to 3766,16 catechin milligram equivalent per extract gram (mg EC/g) of tannins and 1,03 to 8,39 milligram per extract gram (mg/g) of anthocyanins. Red1 and Red2 showed higher tannin contents, while Red2 exhibited superior amount of anthocyanins and total phenolics. Brown3 presented higher flavonoid quantity. Green, Red1 and Red2 PEE showed the lowest levels of flavonoids, but the higher antimicrobial activity. Most PEE exhibit bactericidal activity at a concentration of 1.6 mg/mL. Brown4 PEE showed the worst capacity to inhibit S. aureus. Green PEE showed to be the most efficient in both preventing and disrupting biofilm. All PEE studied exhibited a better inhibitory activity prior-to than post-biofilm formation. According to non-parametric Spearman correlation analysis, there seems to be a significant negative correlation between the ability to disrupt biofilm and both tannins and anthocyanins contents.
