title: Strategies for the Consecration and Appreciation of Mathematics through OBMEP

description: Abstract It is presented in this article some research results on the Brazilian Public Schools Mathematics Olympiads, OBMEP (Portuguese acronym). It is the largest Mathematics Olympiads worldwide, promoted and organized by trained mathematicians, covering schools in more than 99% of the municipalities in Brazil. The article aims to present a sociological view of this competition, according to the theoretical-methodological framework of Pierre Bourdieu (1930-2002). Based on a design in the mathematics field, it is possible to interpret OBMEP as a strategy for mathematicians to value, enshrine, and legitimize their way of doing and seeing mathematics, imposing it on the school. Documents such as posters, dissemination sites, articles, and other materials in the public domain are analyzed. The analysis shows that there are practices of inculcating beliefs, valuing, and legitimizing academic mathematics. It is also conveyed, through OBMEP, that academic mathematics is the basis and lever for the scientific and technological development of the country.

title: Medical identity: the impact of first contact with patient in medicine student’s empathy

description: Abstract: Introduction: Empathy is defined as the ability to listen and understand the other, thus becoming an essential component in the doctor-patient relationship. Studies indicate that the opportunity to make contact with the patient early in the course raises awareness of the importance of empathy in the relationships. Thus, such contact, in the first semesters of medical school, enables students to enhance their empathic skills, permitting the construction of a broader and more complete professional identity. Objective: The study aims to evaluate the influence on the empathy of medical students through the interaction with patients in the discipline of Semiology I, during the second year of undergraduate school. Method: Observational and prospective study with medical students from a private medical school in Vitória (ES), enrolled in the theoretical-practical discipline of Semiology I in 2019/2 and 2020/1, through the application of questionnaires, before the first practical activity in the ward and after the last one. Sociodemographic variables and empathy score were analyzed. The differences between the semesters were evaluated by Chi-square, Fisher’s exact or Mann-Whitney tests. The relationship between sociodemographic variables and empathy was assessed by the Mann-Whitney and Kruskal-Wallis tests. The influence of contact with patients on students’ empathy was analyzed by the Wilcoxon test, all with 95% significance. Results: The sample consisted of 38 students in 2019/2 and 60 in 2020/1. Only the associations between contact with the patients in the wards and the empathy score (p=0.008) and gender and the empathy score (p=0.000) were significant; empathy was greater among women and at the end of the discipline experience. Conclusion: The interaction between medical students and patients during the discipline of Semiology I was able to positively affect empathy, corroborating the literature. The higher levels of empathy among women also corroborate the literature. The obtained results reflect only a specific semester of the course, not the students’ overall empathy profile, levels of empathy at different moments of undergraduate school, or their behavior.

title: GRAPHEN-PHENYL-NH2 AS NANOCARRIER: A DENSITY FUNCTIONAL THEORY STUDY

description: Recently, graphene and modified graphene as one of the most suitable and the most important carbon nanomaterials have been introduced for drug delivery. In this paper, we have studied the binding characteristics of the EDC-NHS cross-linking process of graphene-phenyl-NH2 and 5-aminolevulinic acid (ALA) drug in both gas and solvent phases by density functional theory calculations. For describing binding properties and reaction nature between graphene-ghenyl-NH2 and ALA drug, quantum molecular descriptors, topological analysis, natural bond orbital analysis, analysis of the bond order, the density of states, and analysis bond length was investigated in solvent and gas phases. Due to the results, the complex of the graphene-phenyl-NH2 @ALA turns to absorb more electrons in water solvent than gas phase. Furthermore, the binding of graphene-phenyl-NH2 and ALA is mainly based on covalent interactions, and bond order of graphene-phenyl-NH2 @ALA complex is one in solvent and gas phases. The praphene-phenyl- NH2 @ALA complex has displayed a meaningful improvement of electronic and structural properties. Therefore, it represented that praphene-phenyl-NH2 being combined with the ALA drug is appropriate for use in drug delivery.

title: Correlation between standing posture during work and low back and lower limb pain among cleaners and caregivers of older adults

description: ABSTRACT Maintaining a standing posture during work has been associated with musculoskeletal symptoms. Few studies, however, assess the standing time using objective measures. Thus, this study aimed to verify whether standing time at work is associated with lower back and lower limb pain in the last seven days and last 12 months in caregivers of older adults and cleaners. This is a cross-sectional study. Standing time at work was quantified using inclinometers attached to the workers’ thigh and spine. Musculoskeletal symptoms were assessed using the Nordic Musculoskeletal Questionnaire. Data were analyzed using the point-biserial correlation coefficient (rpb) between standing time at work and the presence of musculoskeletal symptoms. The analyses were performed using the SPSS software, adopting 5% significance level. Workers spend most of their time standing still (41.3%) or walking (39.3%). The presence of symptoms in the lower back was positively correlated with standing time (rpb=0.52; p&lt;0.05). Walking time was negatively correlated with symptoms at the hip in the last 12 months (rpb=−0.53; p&lt;0.05) and running time with symptoms at the hip, in the last seven days, (rpb=−0.43; p&lt;0.05) and the lower back (rpb=−0.43; p&lt;0.05). Longer standing time was correlated with the presence of symptoms in the lower back. Meanwhile, less time walking and running were correlated with the presence of musculoskeletal symptoms in the hips and lower back.

title: INVESTIGATION OF TACTILE GAIT PARAMETERS BASED ON DEEP LEARNING OF ENERGY CONSUMPTION ESTIMATION ALGORITHM IN SPORT

description: ABSTRACT Introduction In medicine, Deep Learning is a type of machine learning that aims to train computers to perform human tasks by simulating the human brain. Gait recognition and gait motion simulation is one of the most interesting research areas in the field of biometrics and can benefit from this technological feature. Objective To use Deep Learning to format and validate according to the dynamic characteristics of gait. Methods Gait was used for identity recognition, and gait recognition based on kinematics and dynamic gait parameters was performed through pattern recognition, including the position and the intensity value of maximum pressure points, pressure center point, and pressure ratio. Results The investigation shows that the energy consumption of gait as modeled analyzed, and the model of gait energy consumption can be obtained, which is comprehensively affected by motion parameters and individual feature parameters. Conclusion Real-time energy measurement is obtained when most people walk. The research shows that the gait frequency and body parameters obtained from the tactile parameters of gait biomechanics can more accurately estimate the energy metabolism of exercise and obtain the metabolic formula of exercise. There is a good application prospect for assessing energy metabolism through the tactile parameters of gait. Level of evidence II; Therapeutic studies - investigating treatment outcomes.

title: Monthly phone calls and calendars to record falls rate in community-dwelling older adults included in a randomized clinical trial

description: ABSTRACT This longitudinal study aimed to analyze monthly phone calls and calendars as a mean to record falls rate in community-dwelling older adults over 22 weeks, and to verify factors related to adherence to the falls calendar. Participants underwent an assessment composed by anamnesis, level of physical activity, neuropsychological measures, and mobility. They also received a schedule of falls that should be completed over 22 weeks, on the day(s) a fall occurred. Moreover, the volunteers received monthly phone calls to inquire about occurrence of falls over time. For data analysis, a α=0.05 significance level was adopted and the SPSS software (20.0) was used to perform statistical tests. The two tools were compared regarding “sensitivity” and “specificity.” In total, 52 older adults composed the final sample, with a mean age of 70.5 years old. The adherence to the calendar was 63.4% compared to phone calls. Of nine participants who reported falls by phone calls, three notified them in the calendar, resulting in a 33% sensitivity. Out of the 43 people who did not report falls by phone calls, 31 delivered the calendar without registration. Thus, the specificity of the calendar was 72%. Schooling level, Mini Mental State Exam score and the Addenbrooke’s Cognitive Examination (revised version) score significantly influenced adherence to the calendar. In conclusion, there was a greater registration of falls by the monthly phone call compared to the calendar tool in community-dwelling older adults.

title: Interdisciplinarity between Mathematics and Physics in a Teaching Degree to measure the Sun’s altitude

description: Abstract In education, the possibility of working on different subjects in an interdisciplinary way has been increasingly appreciated by teachers and educators. This study, which follows in this direction, has as its starting point discussions with students of the Mathematics Teaching Degree who emerged from the use of the new instrument to find the altitude of Sun and mobilized concepts from physics. In view of this fact, the objective is to discuss the use of this instrument as a possibility for interdisciplinarity between the teaching of Mathematics and Physics in the Teaching Degree. Therefore, the study is developed based on a qualitative research approach focusing on the interpretive characteristics that it can assume. From what can be seen the potential of the aforementioned instrument lies in the fact that the use of the apparatus mobilizes concepts of mathematics and physics, in such a way that students can understand how the concepts in these areas are related. This fact, added to the practical context in which the instrument is inserted, opens the possibility of cooperative work in the training of teachers, considering elements related to the construction of interdisciplinary scientific knowledge, the unfolding of interdisciplinary knowledge and the teaching experience. Thus, it is concluded that it is feasible to think about interdisciplinary work proposals between mathematics and physics based on the use of the instrument. An interaction in this sense can, in addition to favoring the overcoming of the idea of fragmentation of knowledge, also contribute to the construction of interdisciplinary knowledge.

title: DIAGNOSTIC TESTS FOR SARS-COV-2: A CRITICAL REFLECTION

description: The new coronavirus, called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), was discovered in late December 2019 after cases were reported in the city of Wuhan, China. In January 2020, the World Health Organization (WHO) officially declared the Coronavirus Disease 2019 (COVID-19) as a pandemic, which has an official record of around 500 million cases and more than 6.0 million deaths in worldwide. An important factor in controlling the pandemic is the development of more effective and efficient diagnostic tests. In this context, this review has as its main proposal to discuss the effective differences between the possible diagnostic tests, the implications of molecular and serological methods available on the market and the analytical and clinical parameters involved in the development and application of these methods.
