Evaluation of the antioxidant activity and mutagenicity of Brazil nut (Bertholletia excelsa Bonpl.).
No full textThis study evaluated the antioxidant capacity and the genotoxic and antigenotoxic effects of the fixed oil of B. excelsa Bonpl. in peripheral blood of Swiss mice. For the antioxidant capacity, were used the β-carotene/linoleic acid and DPPH methods. In the genotoxicity assay, were used healthy, 6-7 week old male Swiss mice, and there were six animals per group. For the genotoxic test, animals were treated with different concentrations of B. excelsa (500, 1.000 and 2.000 mg/kg body weight bw) in 0.5 mL orally. For the antigenotoxic test, animals were treated with predetermined concentrations, followed by intraperitoneal injection of doxorubicin (DXR 15 mg/kg bw) in 0.3 ml, in addition to the negative group (water) and dimethylsulfoxide (200 μL). Peripheral blood samples were collected 24 and 48 hours after the treatments. The frequency of micronucleated polychromatic erythrocytes (MNPCEs) was obtained from the analysis of 2.000 MNPCEs/animal. After data analysis, the conclusion was that the fixed oil of B. excelsa showed excellent protective activity by the β-carotene/linoleic acid method, demonstrated absence of genotoxic effect, and significant antigenotoxic effect according to the protocols and treatments performed in this study
Use of Physical Education Classes as a Didactic Laboratory for Teaching Mathematics: An Example with a Quadratic Function
No full textThe research objective of this study was to evaluate the use of Physical Education classes as didactic laboratory for lessons in Mathematics, presenting an alternative way to conduct classes, mainly of quadratic functions, illustrating basic concepts such as graphs plotting and determination coefficients, analyze if such use achieves some of the goals of using a Didactic Laboratory in addition to research ways to interdisciplinary with Physics. Discusses an action in which students work in groups to solve problems proposed based on empirical data obtained through play activities and measures of athletics values practiced by the students allowing may have the opportunity to produce arguments and more meaningful answers, which would improve the overall learning. The athletics and recreational activities are then used as problematic objects both empirically and qualitatively. As a result, it was observed that some of the objectives of a Didactic Laboratory are achieved when using the Physical Education classes and it appears that this feature is much more available in public schools than they are equipped with a science laboratory
Active Teaching-Learning Methodologies in an Undergraduate Course of Medicine with a Traditional Curriculum: Students’ Perception
No full textThe current technological configuration added to the present social demands in health make it necessary to review the teaching-learning methodologies applied during the graduation of the medical professional. Those necessities are addressed by the National Curricular Guidelines, which preconize the adoption of methodologies that stimulate the student's autonomy and put the faculty in compliance with the current situation. To obtain a panorama about the medical students’ perception in a college of a inland city of the São Paulo state in relation to the Active Teaching-LearningMethodologies (ATLM) this cross-sectional, descriptive-exploratory, quantitative analysis was carried out where the participants were students of the Medical School of São José do Rio Preto - FAMERP in 2017. Through a mixed questionnaire, that is, with open and closed questions, data were collected necessary to reach the objective. A total of 364 students participated, of whom 70.9% agreed they would like to use ATLM more often. Regarding the role of the student: 80.7% agreed that ATLM stimulate the study; 73.3% agreed that group activities support learning; 44.2% disagreed that students are not prepared for ATLM due to lack of maturity and 51.1% agreed that they are unprepared to use ATLM for being accustomed to traditional teaching methods. Data show that, even though they do not attend classes with ATLM frequently, the students can be very interested in execute them. Emphasis is given to his intense perception of learning in these moments. The student profile that compares with the ATLM is the one that knows them, that is, those who have had contact with such methodologies want to use them more frequently. In addition, students consider that the teachers’ role should be that of a learning facilitator, who guides the studies so that the academic goals are achieved
Switching from face-to-face to electronic-mediated education caused by COVID-19 pandemic: An analysis of student perceptions
No full textMozambique, like several other countries in the region and all over the world, faces the dilemma of the need to guarantee the minimum learning conditions for students during the state of emergency due to COVID-19. It is in this sense, which the present study aimed to analyze the perceptions of students of the Pedagogical University of Maputo (UP-Maputo) in the use of electronic platforms as a resource to support classroom teaching during the State of Emergency. The research had a quanti-qualitative character, where the analysis and control of the different variables was foreseen. It consisted of collecting information on the objectives of operationalizing the teaching and learning process in the face of the COVID-19 pandemic, through the application of an electronically administered questionnaire. A sample of 1787 students was obtained, corresponding to 13.61% of the universe of students enrolled in the year 2020. The survey showed that most of the students, around 64% used some electronic platform to support their teaching and on-site learning process, after the declaration of a state of emergency the percentage of users of electronic platforms increased to 100%, highlighting the use of WhatsApp to the detriment of the others (SIGIUP, MOODLE® Institutional, Google Classroom and ZOOM®). The device they use, because 95% of the students access the platforms using their mobile phones, justifies the massive use of WhatsApp. Regarding the use of different electronic platforms, most of the students revealed a platform usage that varies from “Many Times” and “Always”. Students refer to the need for training in the use of the different platforms made available to them to support their teaching and learning process. The research made it possible to conclude that students are aware of the need to appropriate the new form of teaching they are subject to, despite having significant financial difficulties in the acquisition of internet packages and in the use of some of the electronic platforms made available for learning

Scientific Production and Intellectual Property: Analysis of the Correlations between Evaluation and Valuation of Patents in the Transfer of Technologies in Public Research Institutions
No full textIn Brazil, Public Research Institutions (PRI) are agents that promote innovation and technological production. The role of these institutions in social and regional development is to provide scientific and technological production and make it available for productive arrangements. This study aims to relate the evaluation and valuation of patents with the processes of Technology Transfer in Public Research Institutions in Brazil. To justify the execution of the study, it is observed that it is necessary to improve the use of technologies created in PRI so that society can take advantage of the advances promoted in scientific research, and so that the distance between industry and academia is minimized. We researched 30 Public Research Institutions, in five variables collected on the platform of INPI (National Institute of Industrial Property), ESPACENET (European Patent Office) and BDTD (Brazilian Digital Library of Theses and Dissertations). In possession of the data, the Shapiro-Wilk test and the Spearman correlation coefficient were used used to analyze them. The R software was used to apply the statistical methods. For data discussion, the reports of FORMICT (Information Form on Intellectual Property Policy of Scientific and Technological Institutions) were analyzed to guide the arguments. The data did not show normality and have moderate and strong correlations, the significance of the correlations is strong or very strong. It is believed that the patent evaluation and valuation processes have space for improvement and thus can enhance the Transfer of Technologies of PRI
The importance of community action in the process of implementing an educational institution and its impact on extension activities
No full textThe Federal Institutes of Education (IFs) are intended to collaborate with the regional innovation systems, encouraging after roduction of knowledge and innovative technologies and activities constituting promising strategy for Brazilian regional development. One way to measure whether the institute's purpose is being fulfilled is through outreach activities with the community with a view to local and regional economic and social advancement. Therefore, the objective of this article is to analyze the process of implementing an IF, as well as its impact on the community. Methodologically it was Documentary research was carried out on the process of community participation in the implementation of the IF in the city, as well as interviews were conducted to ascertain the view of this determining actor regarding the return to society, also contemplating extension actions. It was concluded that the engagement of the local population in the choice of the city was fundamental, causing other cities in the region to join efforts to capture the institute, just as it generated a positive impact in the entire region by providing an opportunity for qualification, which before it was carried out distantly, causing the success of the young population or even the lack of training of this public for financial reasons. As for the extension actions, the institute analyzed performs them according to the local context, filling the gaps, as the purpose of its creation
Perceived Performance of Cooperating Schools: Gearing Towards Future Policies
No full textPart of providing quality education is the quest to continually improve one’s service delivery since competition is now the essence of time. In the academic field, inputs in the life of pre-service teachers are considered to be of utmost significance. These include the cooperating teachers as well as the cooperating officials who may directly or indirectly influence the future would-be-teachers, the learners who may inspire them more and the learning environment that may significantly affect their desire to enter the world of teaching upon completion of the internship. This study determined the performance of the cooperating schools as perceived by the selected elementary and secondary education students enrolled during the second semester of the calendar year 2019 in one of the higher education institutions in the Philippines offering a teacher-education program. Employing the quantitative (descriptive) research design, the results revealed that the cooperating schools’ over-all performance was excellent. However, the performance rank of the indicated factors along the cooperating schools’ selected variables (i.e. cooperating teachers, cooperating officials, learners, and learning environment) vary. In general, among all the factors included in the four main elements in the cooperating school; the learning environment particularly on functional, medical and dental facilities gained a very good rating.
