title: Perception of health professionals on the prone position as a therapeutic strategy for patients with COVID-19

description: ABSTRACT The COVID-19 pandemic has led to a great number of hospitalizations. A considerable number of cases progress to the severe form of the infection and death. Prone positioning is a therapeutic strategy with strong evidence of reduced mortality in patients with acute respiratory distress syndrome (ARDS). This study aims to assess if the prone positioning strategy is used by health professionals in hospitals to treat patients with COVID-19 on invasive mechanical ventilation and the professionals’ perception of its effect on the mortality rate. This is a cross-sectional study, with a convenience sample composed of health professionals of both sexes working in hospitals throughout Brazil. Participants answered an online questionnaire composed of 16 questions using Google Forms, from July 2020 to September 2020. A total of 455 questionnaires were answered. Prone positioning is routinely performed in hospitals where 386 (95%) of the responding professionals work. Among them, 374 (96.9%) consider that the prone position strategy reduces hypoxemia and 289 (74.9%) consider that it reduces mortality in patients with COVID-19 and ARDS on invasive mechanical ventilation. Finally, most health professionals working in Brazilian hospitals perform and believe that prone positioning reduces hypoxemia and mortality in patients with COVID-19 on invasive mechanical ventilation.

title: Dialogues between the capital and the interior: singularities of rural teacher training in Paraná

description: ABSTRACT The article analyzed the training of rural teachers in the State of Paraná, through the Regional Normal Course, when this type of teacher training was created and extinguished in the period from 1946 to 1968. The analysis focuses on investigations within the scope of doctoral theses and master’s dissertations that have as object of study the Regional Normal Course of the State of Paraná. In particular, the role of Erasmo Pilotto and Diva Vidal is highlighted in the actions facing the intense process of interiorization of the Regional Normal Courses. Cultural History is used as a theoretical framework, based on the concepts of school culture by Juliá (2001) and strategies and practices by Certeau (1998). As documentary sources, we used the theses and dissertations in the area of Education, documents from the Public Archive of the State of Paraná, the Library of the State Secretariat of Education, the Public Library of the State of Paraná, the Secretariat of Education and Culture and/or Normal Education Service, including originals from CD-ROM of Gonçalves (2016) etc. Considering the number of Normal Regional Courses (121 courses in 1964) and the location of 12 works, this preliminary assessment clarifies the uniqueness assumed by the Normal Regional Course of the State of Paraná, the result of the joint effort of well-known educators (Erasmo Pilotto and Diva Vidal) and anonymous professors who lived with the consonance and contradiction prescribed and practiced and developed strategies and tactics to deal with the problem of rural teacher training.

title: Does the quality of the home environment influence the functional abilities of infants in early childhood?

description: ABSTRACT The literature associates child development with the quality of the environment stimulation. However, few studies verify if this is associated with the infant’s functional abilities. This study aims to assess which opportunities in the home environment are associated with functional mobility skills and social function of infants in early childhood and explain them. This is a cross-sectional and exploratory study with 74 infants aged from six to 18 months. The affordances in the home environment motor development - infant scale instrument was used to evaluate the opportunities in the home environment. The pediatric evaluation of disability inventory was used to assess the infants’ functional abilities. We observed that infants’ mobility can be explained in 45.6% (Adjusted R²=0.45) and social function in 30% (Adjusted R²=0.30) by the amount of gross motor skills toys, equipment and variety of stimulation in the home environment. We concluded that positions, toys, and materials that keep the infant more restricted and less active have a negative effect. On the other hand, toys that offer greater displacement and interaction favor the functional mobility skills and social function.

title: Essay on territories induced by public policies in Brazil: the experience of the Alto Oeste Potiguar

description: Abstract The territorial approach, when conceiving the rural as a space, proposing the overcoming of the rural-urban dichotomy and being concerned with the need to articulate the top-down and bottom-up actions, has been considered a relevant strategy for the discussion and promotion of rural development processes proving in the implementation of public policies. In Brazil, the National Program for Sustainable Development of Rural Territories (Programa Nacional de Desenvolvimento Sustentável dos Territórios Rurais in Portuguese, or PRONAT) and the Territories of Citizenship Program (Programa Territórios da Cidadania in Portuguese, or PTC) stood out. These programs induced inter-municipal socio-productive arrangements aiming to reduce inequalities and promote economic dynamism. This article analyzes the limits and possibilities of these actions, taking as a case study the Alto Oeste territory, located in the state of Rio Grande do Norte (Brazil). Contributions of literature are used to the analysis of territorial development, and documents on the process of constitution and functioning of the territory are analyzed, fieldwork is carried out with semi-structured interviews with members of the Collegiate, and secondary data are analyzed. In addition to some possibilities found, such as the creation of a concertation space and the discussion of projects that would benefit the main guiding idea of the territory (cattle culture), the experience of this territory suggests the low participation of public and private actors in the Collegiate, embeddedness power relations, reduced social capital, and problems related to projects financed. It is concluded that the territory has suffered relevant limits to incorporate the territorial approach of development, raising a set of actions to mitigate this problem. Moreover, it is understood that the territorial approach is relevant, but requires a more concrete interaction between state and society in the construction of the development.

title: Physical capacity assessment in patients hospitalized with COVID-19 diagnose

description: ABSTRACT SARS-CoV-2 infection can cause severe acute respiratory syndrome (SARS), leading to hypoxemia. Physical capacity assessment can be performed before hospital discharge using submaximal exercise testing. This study sought to assess physical capacity and exercise tolerance with the six-minute step test (6MST) in hospitalized COVID-19 patients who required oxygen (O2) support during hospitalization. A prospective, interventional study was conducted with patients aged from 18 to 90 years who required oxygen therapy during hospitalization. Assessment was performed using Perme Score, followed by the 6MST tests, assessing the peripheral oxygen saturation (SpO2), heart rate (HR), blood pressure (BP), and subjective exertion perception by Borg Scale, before and immediately after the 6MST. A total of 31 patients, with a mean age of 51.9 years, were evaluated. Nasal cannula (NC) was the most used device (64.5% of patients). Regarding HR, BP, and Borg Scale, their mean value increased after 6MST. SpO2 showed a lower mean value after 6MST. Out of the 86.9% of patients who completed the test, 48.3% completed it with interruptions, and 12.9% had to suspend it. The 6MST was able to assess physical capacity and exercise tolerance, proving to be an effective tool for evaluating COVID-19 patients.

title: Difficulties with the Fraction as an Operator in Primary Education Sixth Grade Students

description: Abstract This exploratory work seeks to detect the difficulties existing in a group of students between eleven and twelve years of age when faced with the fraction as an operator on natural or fractional numbers, in two different contexts: problem-solving and formal operations, and using arithmetic and graphical methods. A test composed of two arithmetical-verbal problems was designed when the fraction acted on a number a) natural and b) fractional. Likewise, a formal operative activity was proposed to them that reproduced the necessary operation in the previous problems. The results show greater difficulties when the fraction acts against a fractional number than when it has a natural number. Along the same lines, graphic resolution is not a tool that increases resolution success. Finally, the knowledge of the fraction operation as an operator on fractional number is strongly related to the resolution of the associated problem.

title: The Singapore Bar Model for solving arithmetical and algebraic problems

description: Abstract Figurative representations play a significant role in learning and conceptual understanding of mathematics, for example, the figures in demonstrations in Geometry. An approach that has become popular for its potential to solve problems using figural representations is the Singapore Bar Model (‘ Model’ Method ). Mobilized by these aspects, we carried out a literature review aiming to present the Singapore Bar Model and its contributions to mathematics learning. The research empirical material was gathered from a search carried out in the Google Scholar platform. The results of the analyzed works point to contributions to the learning of mathematics in the following aspects: protagonism assumed by students in the construction of knowledge, deepening of mathematical concepts and relationships, enhancing problem-solving skills, and use of more abstract representations, as well as anticipation of advanced troubleshooting. In this perspective, the Bar Model allows promoting changes in mathematics teaching and favors student learning.

title: Morphophysiological responses of Setaria viridis to cold stress

description: Abstract The objective of this work was to determine the suitability of Setaria viridis as a model plant in studies to validate candidate genes for cold tolerance by evaluating the response of two of its accessions to different durations of abrupt or gradual cold stress in the vegetative and reproductive stages. Plants of accessions A10.1 and Ast-1, cultivated at 25°C, were subjected to the following cold stress treatments: gradual reduction in temperature from 25 to 0°C, 5°C at a time, every 24 hours in a same chamber; or abrupt reduction in temperature, by transferring plants from a chamber at 25°C to another at 0°C. Plants were kept at 0°C for 3, 5, or 10 days, after which temperature was increased back again to 25°C; a control group remained at 25ºC. Low temperatures – reduced abruptly or gradually – caused a decrease in the gas exchange rates and shoot and root biomass of the plants, besides damage to their photochemical apparatus; the longer the cold lasted, the more pronounced the effect was. Regardless of stress duration, plants recovered and completed their life cycle. The studied accessions are tolerant to cold and, therefore, are not suitable as a model plant in studies to validate candidate genes for cold tolerance.

title: Effect of humic acid on the growth of seedling tomato (Solanum lycopersicum) and melon Cucumis melo)

description: Abstract This study evaluated the effect of HS extracted from mineral coal on the growth of tomato (Solanum lycopersicum) and melon (Cucumis melo) plants to determine the role that humic substances (HS) play as promoters of plant growth. Three concentrations of HS were evaluated in 200 grams of soil. The fertilizer (urea 0.3%) and humic acid in concentrations of 0.05%, 0.1%, and 0.2% were added directly and at the same time to the amount of soil, using a control sample without the addition of humic acid. Increase measurements were made at three-day intervals up to 45 days. Plants treated with high concentrations of HS demonstrated a significant increase in roots (p&gt;0.05). In both plants, the concentration of 0.2% in HS showed the greatest increase in growth, with the melon plant showing the greatest variation as time passed, with its highest peak in 36 days (13.1 ± 0.05cm) of the experiment, while in the tomato plant the maximum growth occurred in 30 days (9.2 ± 0.01 cm). The Dunnett test showed that there was no statistically significant difference between the control and the concentrations of 0.05% and 0.1% (p&gt;0.05), while among the control and the soil sample with a concentration of 0.2% there was a statistically significant difference (p&lt;0.05). The results show a notable influence of humic acid on the growth of the studied plants, especially at high concentrations.
