Obstacles to parental involvement in children\u27s education: New teachers\u27 perceptions and strategies
No full textThis study explored new teachers’ perceptions of, and strategies for overcoming the obstacles to parental involvement in children’s education. 30 elementary school teachers with 1 to 5 years’ teaching experience were interviewed. Data were first coded through the grounded theory approach and then analyzed by case and cross case. As found out, obstacles to parental involvement were related to parents’ lack of cognitive readiness, affective preparedness, and physical resources. Strategies new teachers employed to overcome their perceived obstacles included cognitively informing, persistently outreaching, psychologically disarming or comforting, and consciously attending to parents’ individual differences, needs, or personal preferences. Lessons learned from this study will inform both in-service teachers’ efforts to engage parents for optimal student learning outcomes and teacher educators’ endeavors to prepare prospective teachers for more effective teacher-parent communication
A diagnostic challenge in an individual with Paracoccidioidomycosis during hospitalization in times of COVID-19
No full textParacoccidioidomycosis (PCM) is a deep fungal infection, endemic with considerable morbidity in South America, whose first symptoms can occur in the oral cavity. A 47-year-old male patient, leucoderma, living on the streets, presenting dyspnea, pain during the speech, and dysphagia, was referred for admission to the ICU for suspected COVID-19 infection. The intensive care physician\u27s evaluation revealed a tongue lesion with suspected carcinoma. By dentist investigation, was observed the presence of moriform lesions with high borders delimitation in the tongue. Also, granulomatous ulcers with irregular texture, suggesting moriform stomatitis, the chest tomography revealed diffuse thickening of the bronchial walls, indicating chronic bronchopathy with discrete centrilobular nodules, sometimes confluent. Incisional tongue biopsy associated with lung imaging confirmed the diagnosis of PCM, and the patient was referred to the referral center for the treatment of fungal diseases. The involvement of the oral environment as a region to the appearance of detectable first symptoms of PCM suggests the need for the oral evaluation by a specialist as a diagnostic tool

No full textIn the article, we seek get the thinking of the Paul Lafargue, in his work “ The right to be lazy” comes to question by proposing a different perspective, a new direction to human life that will only be achieved with the end of the exploitation of the individual by the individual. The objective of this work is to verify the contemporaneity of Lafargue\u27s writings, comparing whether his analyzes are consistent with the reality of workers in the 21st century
The use of assistive technological tools in people with depression arising from the Covid Pandemic
No full textDepression is a disease that affects approximately 60 million people in the world each year, affecting around 11.5 million Brazilians, which presents in the individual severe anxiety disorders, which may evolve into cases of suicide, ranking among the 20 major causes of death/ year. As a result of Covid-19, approximately 90% of cases of depression in Brazil in the last year increased and people with anxiety crisis and symptoms of acute stress doubled in 2020, and this increases concerns regarding the social isolation that extends. This study aimed to investigate the resources of assistive technologies applied to depressive cases with potential application as treatment mechanisms in the context of the COVID-19 pandemic. This is a study with an exploratory objective, a quantitative approach and a bibliographic procedure and descriptors databases. The study evaluated the presence of 306 articles, being used as a filter the interval between 5 and 10 years of publication. The tools used to depression acquired during the pandemic were also discussed, where the results contributed to broader reflections on the challenges imposed by the pathology. Some interesting results were obtained with the application of Tec. Assistive (AT) depressed patients by Covid-19, highlighting: remote care, electroconvulsive therapy, Deprexis, in addition to art therapy and music therapy, the latter being calls for integrative and complementary practices in health (PICs) with application encouraged by SUS showing great relevance and effectiveness in the treatment. The research carried out has shown the potential of ED tools to address the effects of depression in people with Covid-19. This study encourages the development of new research and the development of instruments that are more specific to this need in order to minimize the problems arising from this disease
A note about a new method for solving Riccati differential equations
No full textAl Bastami, Belić, and Petrović (2010) proposed a new method to find solutions to some Riccati differential equations. Initially, they obtain a second-order linear ordinary differential equation (ODE) through a standard variable change in the Riccati equation. They then propose a new variable change and discuss the resolution of the resulting ODE in two cases. In the first one, the resulting ODE has constant coefficients. In the second case, they claim that it is possible to arbitrarily choose one of the resulting ODE coefficients and solve particular Riccati ODEs. We show in this work that all Riccati equations that belong to the first case can also be solved by Chini’s method. Furthermore, we show that any Riccati equation fits the second case and that the choice of the resulting ODE coefficients is not free
Wood residues from Zygia racemosa (Ducke) Barneby & J.W. Grimes: Secondary metabolites, physical properties and anatomical aspects of the wood: Secondary metabolites, physical properties and anatomical aspects of Zygia racemosa
No full textZygia racemosa (Ducke) Barneby & J.W. Grimes (syn. Pithecellobium racemosum Ducke) is a large tree with its geographic distribution restricted to South America (Brazil, Colombia, Guyana, French Guiana, Peru and Suriname). It has a wide occurrence in the Brazilian Amazon and is abundant in campinarana and terra firme forest. In the present work, we evaluated the secondary metabolites, physical properties and anatomical aspects of wood residues of the species. The chromatographic fractionations of the hexane extract led to the isolation of steroids identified as spinastenone (1) and spinaterol (2). The methanol extract provided the steroids 1 and nonanoate-cholest-7, 22-dien-3β-ol (3), the triterpenes oleanolic acid (4) and 3β,21β-dihydroxyolean-12-en-28-oic acid (5). The basic density found was 0.81 g/cm3 and the anisotropic factor was 1.90, which confirms its excellent quality. The acquisition of a sample of wood residues from Zygia racemosa was an opportunity to generate knowledge regarding the secondary metabolism, the physical properties and the anatomical aspects of the wood of this species. The steroids and triterpenes identified suggest that they are associated with plant defense in Z. racemosa
Biological Assessments of Baccharis dracunculifolia DC from a Cerrado fragment in Central-West Brazil
No full textBaccharis dracunculifolia is used as an herbal medicine, and green propolis, synthesized by Apis mellifera bees from it, has inflammatory, antioxidant and antimicrobial principles. This bee product is effective in combating a series of microorganisms in folk medicine, so it is essential to develop research to prove this effectiveness. The objectives of the work were to analyze the microbiological profile, dose the flavonoids and verify the plant\u27s antioxidant activity. The aerial parts were collected in a fragment of cerrado sul-mato-grossense and processed, obtaining extracts with hexane, ethyl acetate and ethanol. For microbiological analysis, Staphylococcus aureus bacteria was seeded in agar and filter discs were soaked with the extracts and, together with the control group, were placed in Petri dishes for subsequent measurement of inhibition halos. To measure the flavonoids and evaluate the antioxidant activity, processed leaves were taken to Soxhlet for extraction in methanol. An aliquot was read in a spectrophotometer with different concentrations of quercetin to build a standard curve. The antioxidant assay was based on the radical reduction and development method using DPPH. As a result, all extracts showed inhibition of bacterial growth, indicating antimicrobial activity of the plant. Flavonoids with satisfactory antioxidant activity were also found. Taking into account that B. dracunculifolia is used as a medicinal plant, studies such as this one can corroborate with such use, since the scientific proof of possible herbal medicines is essential for the pharmaceutical industry and for health professionals, contributing to the evolution of medicine

For this, a project was applied in the second semester of 2017, lasting 26 class hours, in a class of the 2nd year of high school, composed of 22 students from a public school in the interior of São Paulo State - Brazil. This teaching proposal appropriated Didactic Engineering as a Research methodology, which enabled the development of a didactic sequence. This in turn was divided into six steps, which approached counting techniques, without the use of formulas, through the encryption of binary numbers, Caesar\u27s code and the encryption present in the film: The Da Vinci Code. This study was exposed by students participating in the project at the school\u27s Science Fair. In order to analyze the learning evolution of the participating students, a pre-test and a post-test were applied, which presented a satisfactory evolution in the students learning. It was also possible to realize, during the project application, the improvement and development of the skills of: teamwork, self-confidence, oratory, time management and autonomy in the pursuit of knowledge
Perception of Health Care Workers Regarding Ludic Activities in Pediatric Hospitals
No full textInfant hospitalization is a difficult process for a developing child because it is related to a series of losses and trauma. In this sense, ludic treatment contributes to ease hospital permanence, thus favoring child development and, in certain aspects, even the cure. The sense of life finitude afflicts the child, the family, and those that accompany it during hospitalization. In this context, the perceptions of workers composing the multidisciplinary health care team regarding the application of ludic activities in pediatric public hospitals in São Luís/MA were investigated. Therefore, a descriptive exploratory research was carried out in two hospitals that had a pediatric treatment macrostructure within their functional dependencies with all medical and complementary specialties available for the infant public, thus comprising a multidisciplinary health team. Participants comprised 8 workers (2 doctors, 2 nurses, 2 psychologists and 2 occupational therapists), including 6 women and 2 men with an average of 6 years of professional experience in pediatric hospitals. Data were collected through semi-structured interviews. Results indicated that ludic activities are relevant for children socialization and integration in the hospitalization reality. The health care workers from the multidisciplinary health team emphasize that ludic such activities in pediatric hospitals contribute to the child’s health recovery and therefore to the pathology treatment
Modeling of urban bus drivers thermal sensation vote as a function of the thermal comfort parameters
No full textResearch into thermal comfort in vehicle environments has been gaining prominence among researchers due to the impacts generated, which range from maintaining the thermal sensation of the occupants, to ensuring the satisfactory performance of drivers in terms of safety in traffic and in energy sustainability. With this background, this study aimed to evaluate the thermal comfort parameters that influence the thermal sensation of urban bus drivers. To this mean, the four environmental parameters in the cabins of urban buses were measured and the two personal parameters of three drivers of the same bus line were estimated, and the influences of these six parameters on the subjective thermal sensation were analyzed using the Ordinal Logistic Regression Models of the Generalized Linear Models methodology. The field survey was performed from September to December 2021 and over three daily trips, totaling 180 measurements of thermal conditions. As a result, both the Predicted Mean Vote index and the thermal sensation votes indicate that the environments of the bus drivers\u27 cabins analyzed are, in general, within the scale of thermal discomfort by heat, with a predominance of the "Warm" class. Furthermore, the model adjustments converged on only three distinct models and they demonstrated that the thermal sensation was influenced by the environmental parameters, and not by the personal parameters. Finally, we concluded that the model that best fit to the sensation was that as a function of the air temperature, with a moderate explanatory ability due to the value of Pseudo R2 = 0.669. In addition, the proportional chance curves of this model indicated the following air temperature ranges for the respective heat thermal discomfort classes: when ta < 28°C, the greater chances are in the choice of thermal neutrality and the other classes of thermal discomfort by cold that were not reached by this research, which were not achieved by this research; for 28°C ≤ ta ≤ 30°C the tendency is higher for a slightly warm sensation; for values in the range 30.5°C ≤ ta ≤ 32.5°C it is more natural that they opine on the heat scale; and for values of ta > 33°C the tendency is for conductors to feel extremely hot
