(Universidade Federal de São Carlos, 2021-05-04) Almeida, Nice Ribeiro de; Pinheiro, Rosa Aparecida; https://lattes.cnpq.br/6292207464385037; https://lattes.cnpq.br/1542185480817206
This research presents the theme "Initial teacher training from the perspective of paid internship: an analysis of the Citizen Training project", whose purpose is to analyze the relevance of initial university training and to investigate how the managers and educators of an Early Childhood Education Center Sorocaba conceives paid internships in early childhood education (day care). Given this theme, try to collect information on field research and bibliographic research on the respect of the internship's contributions in the school environment, and how this can contribute to the academic education of the university student. Before the questions analyzed, research about the quality of university education in teacher training and check if the paid internship, in the scenario of the “Citizen Training” Project, can be understood as a pedagogical training space, in the midst of the meaning strategies built by paid interns, by the teachers and the management team of the Child Education Center located in the North Zone of Sorocaba. In this context, it is opportune to analyze public policies for teacher training for early childhood education. In view of the theme, this paper presents a brief history of the Pedagogy Course in Brazil, clarifying issues that involve the education of childhood teachers and what are the main skills needed to improve teaching practice in Early Childhood Education. Finally, the results of the field research on the Citizen Training Project, its educational objectives, its guidelines and how the paid internship takes place at the Early Childhood Education Center Sorocaba will be presented, from the perspective of contributing to the field of initial teacher education.
Requisitos gerais para a produção de materiais de referência
(Universidade Federal de São Carlos, 2021-05-04) Zamarco, Jonathan Gabriel; Nogueira, Ana Rita de Araújo; https://lattes.cnpq.br/7034773971317045; Pereira Filho, Edenir Rodrigues; https://lattes.cnpq.br/3394181280355442; https://lattes.cnpq.br/9443563719861187
The present work had as objective to raise the main requirements for the production of Reference Materials. These requirements can be classified into Structural, defined by ABNT NBR ISO 17034, in Instrumental, defined by ABNT NBR ISO/IEC 17025 and Production, representing the stages in which the material property values are determined and tested, being guided by ISO Guides 31, 33, 34 and 35. From the various studies involved, such as homogeneity, stability and chemical characterization, it will be possible to estimate the degree of residual heterogeneity and check whether the material has sufficient stability for the intended use, considering the contribution of each study in the final expanded uncertainty. Understanding that many decisions made in different productive sectors are based on analytical results, and the reliability of these results is based on the comparison with metrologically valid standards, it is perceived the importance of expanding the knowledge regarding the production of these materials, satisfying the research and the international trade simultaneously.
Efeito do aspartato sobre o crescimento e formação de biofilmes por Staphylococcus aureus
(Universidade Federal de São Carlos, 2021-05-04) Tanabe, Juliana Miho; Pimentel Filho, Natan de Jesus; https://lattes.cnpq.br/9157232954010211; https://lattes.cnpq.br/2932017562454855
Staphylococcus aureus is an opportunistic pathogen of great relevance, since it is often associated with outbreaks of food poisoning. When submitter to some type of cell stress, certain microorganisms tend to cluster in the form of a biofilm, becoming more resistant to external agents, including antimicrobial treatments such as the use of the bacteriocin nisin. Aspartate is an important molecule for cellular metabolism, as there is evidence of its role in maintaining cellular homeostasis and also in the expression of virulence factors. This study aimed to evaluate the possible influences of the amino acid aspartate on growth, adhesion, and biofilm formation by S. aureus. The influence of the bacteriocin nisin, in subinhibitory concentrations, on the formation of biofilm on a polystyrene surface in the presence and absence of aspartate was also evaluated. Cell growth was conducted in a synthetic medium supplemented or not with the amino acid in two conditions, aerophilic and microaerophilic, in conical flasks under orbital assembly and into 96-well microplates, respectively. Cell adhesion and biofilm formation were studied on two surfaces commonly used in the food industries, stainless steel and polystyrene, and the biofilm formation on this last surface was also evaluated in the presence of subinhibitory dosages of nisin. S. aureus grew reaching maximum absorbance, both in aerobic and microaerobic conditions in synthetic medium with aspartate. Cell adhesion on a polystyrene surface did not show a significant difference (p> 0.05) in the presence or absence of aspartate. On the other hand, in stainless steel surface, the initial adhesion was higher in medium supplemented with aspartate (p <0.05), but there was no difference in the biofilm formed after 24 and 48 h in the presence or absence of the amino acid. Subinhibitory concentrations of nisin did not influence cell adhesion on a polystyrene surface. The results highlight the effect of aspartate on the microbial growth and initial adhesion of the microorganism on stainless steel. Further studies, evaluating different strains of S. aureus, need to be carried out to obtain more conclusive responses to the role of the amino acid for this species.
