title: Computational methodology for the optimal design of steel truss frames integrating MATLAB and FEA platforms

description: Abstract Seeking to define more robust and executable structures, this article presents a computational framework for the optimal design of steel truss frames, which integrates two software of great prominence in structural engineering, MATLAB and ANSYS. Computational interfaces were created to enable the automation of the iterative optimization process. The optimization algorithm and computational interfaces were developed on the MATLAB platform, while structural analyses were performed with the ANSYS Mechanical APDL platform. Some details of the computational implementation are presented herein. The objective is to minimize the cost of structures by determining the optimal positioning of nodal coordinates and the optimal choice of commercially available structural profiles - shape and size optimization, respectively. For shape optimization, a computational model was defined to automatically generate the geometry of the structure, maintaining some intrinsic relations of symmetry and collinearity between elements. The design constraints are critical nodal displacements, stresses, and slenderness of elements, following the requirements of ABNT NBR 8800:2008. To exemplify the application of the proposed methodology, this article presents the optimal design of trusses for roofs of industrial sheds, considering its non-linear geometric behavior, typical of this type of structure.

title: SUPPORTING THE CHOICE OF THE BEST-FIT AGILE MODEL USING FITRADEOFF

description: ABSTRACT The goal of this study is to propose a decision model for supporting the choice of the best-agile model, based on the Flexible and Interactive Tradeoff (FITradeoff) method. This study provides the definition of an extensive set of 38 measurable criteria that were considered for evaluation of the most popular agile process models used in small and medium-scale enterprises. To illustrate the application of the model, we applied it to a set of alternatives that includes DSDM, SCRUM, XP2 and Crystal and an experienced project manager acted as our decision maker during the interactive elicitation process of the FITradeoff. The results show that the FITradeoff is very valuable for this class of problem because of its strong mathematical foundation and the possibility of combining two different ways for modeling the preferences of decision makers, which makes the process cognitively easier than other multi-criteria methods and increase the confidence on the results. Although our study focuses on the context of small and medium-scale companies for software development, the approach can be used to other types of environments, including distributed software development and large enterprises.

title: The Impact of Cultural Factors, The Level of Health Education Received by the Caregivers, and Stigma on Asthma Treatment among Children in Southern Jordan

description: Abstract For asthma treatment in children, caregivers need good knowledge and attitudes regarding the disease and its treatment. This study aimed to determine the impact of cultural factors, the level of health education provided to patients and their families, as well as the impact of stigmatization on the treatment awareness of children with asthma in southern Jordan. A validated questionnaire was used to collect data from a sample of ninety-seven caregivers selected from three hospitals in southern Jordan. Open ended questions were answered after demonstrating the inhaler technique in and evaluated according to the instructions of the National Asthma Education and Prevention Program (NAEPP, 2013). The result revealed moderate knowledge of asthma with a mean score of (22.36/32), as well as moderate knowledge of asthma treatment (24.26/40). A high mean was found for the impact of cultural and environmental factors (22.93/28), whereas low impact was found for stigma with a mean value of (4.73/12). Therefore, to improve future asthma management, additional efforts are required to educate caregivers and improve their asthma awareness and rectify any falsehoods regarding asthma medications by health care providers.

title: Impact of the loading of date palm fibers on the performances of mortars

description: Abstract The development of eco-friendly composites as insulating materials in buildings offers practical solutions to reduce energy consumption, which is why scientists have started in recent decades to search for more sustainable and eco-friendly materials. It is well known that building materials are among the most commonly used materials and have an obvious negative impact on the environment. Therefore, this article presents a study on the use of a new bio-composite material, composed of natural fibers of date palm, cement, and sand. The objective of this study is to assess the thermal insulation properties, as well as the water absorption and mechanical performance of this material for the construction of buildings. The percentage by weight of date palm fiber in the test samples varied from 0% to 30% for a mixture of two fiber sizes equal to 3 mm and 7 mm. The characteristics of these samples were determined experimentally in terms of compressive strength, as well as thermal conductivity. The results show that the introduction of date palm fibers in mortars causes a decrease in compressive strength and thermal conductivity. This study affirmed that the use of vegetable fibers in cementitious composites has a positive effect on the properties of insulations and on the costs.

title: THE PERCEPTION OF CREATIVITY AMONG BRAZILIAN STUDENTS AND TEACHERS

description: ABSTRACT Despite scientific advances in the understanding of creativity, there are still doubts in the definition of this construct by students and teachers. This study aimed to identify the perception of creativity in students (n=74) and teachers (n=24). The average age was 30.5 years, mostly women (70.41%), with higher education (75%), from the Southeast region (58%). The instrument used was an online questionnaire with open questions about the perception of creativity. Through content analysis, it was found that participants describe creativity through cognitive characteristics (fluency, flexibility, elaboration and originality), with teachers showing greater emphasis on the creative environment, while students believe that the person and the process are aspects that can stimulate the expression of creativity. The results are in line with others found in the literature, reinforcing the importance that creativity is inserted in the training of teachers and worked with students.

title: Removal of fluoxetine from water by nanofiltration and reverse osmosis

description: Abstract This paper explores the use of nanofiltration (NF) and Reverse Osmosis (RO) to remove the pharmaceutical Fluoxetine (FLX) from water. This substance can be found in rivers and lakes and requires studies involving the application of efficient technologies for its removal or mitigation. The study evaluated NF and RO membranes as an alternative to remove Fluoxetine from water. NF removed fluoxetine within the range between 50 and 60%, and RO demonstrated higher efficiency in removing the drug (98.8%). RO is a suitable method as a complementary treatment of water to ensure a lower concentration of FLX in water.

title: Antimalarials and macrolides: a review of off-label pharmacotherapies during the first wave of the SARS-CoV-2 pandemic

description: Abstract We critically analyzed clinical trials performed with chloroquine (CQ) and hydroxychloroquine (HCQ) with or without macrolides during the first wave of COVID-19 and discussed the design and limitations of peer-reviewed studies from January to July 2020. Seventeen studies were eligible for the discussion. CQ and HCQ did not demonstrate clinical advantages that justified their inclusion in therapeutic regimens of free prescription for treatment or prophylactic purposes, as suggested by health authorities, including in Brazil, during the first wave. Around August 2020, robust data had already indicated that pharmacological effects of CQ, HCQ and macrolides as anti-SARS-CoV-2 molecules were limited to in vitro conditions and largely based on retrospective trials with low quality and weak internal validity, which made evidence superficial for decision-making. Up to that point, most randomized and nonrandomized clinical trials did not reveal beneficial effects of CQ or HCQ with or without macrolides to reduce lethality, rate of intubation, days of hospitalization, respiratory support/mechanical ventilation requirements, duration, type and number of symptoms, and death and were unsuccessful in increasing virus elimination and/or days alive in hospitalized or ambulatory patients with COVID-19. In addition, many studies have demonstrated that side effects are more common in CQ-or HCQ-treated patients.

title: Better alone? The impact of living arrangements on mortality of Costa Rican older adults

description: Abstract Previous research has shown differentiated effects of living arrangement types on mortality. However, little is known about this phenomenon in Latin America and its multigenerational households. This study measures the relationship between older adults’ living arrangement types and subsequent mortality. Gompertz event history models were performed to estimate mortality differences across living arrangements. We used the Costa Rica Longevity and Aging Study (CRELES) pre-1945 cohort in the 2005, 2007, and 2009 waves. The results show that older adults who live with a partner have the highest survival rates among the categories tested. When controlling for sex and age in the model, the effect of living alone is not different from partnered living. When controlling for socioeconomic and health factors as well, older adults living with their children or others show an increased risk of death by at least 40% (p-value&lt;0.05). The study demonstrates an association between living arrangements and older adult mortality in Costa Rica. Results show that the highest survival chances rely on being partnered and suggest that support exchanges with other family members are not equally effective. Including this variable type in mortality studies is crucial to better understanding how household conditions relate to health and mortality outcomes.

title: Medical students in the Covid-19 pandemic: experiences through narratives

description: Abstract: Introduction: The pandemic caused by the new coronavirus (Sars-cov-2) has resulted in economic, social and mental health consequences for individuals with the establishment of social distancing. Consequently, medical schools suspended their activities, with the need to rethink the structure of academic education, affecting students in the fifth and sixth years with greater intensity. Objective: To understand the emotional, social and academic and professional training consequences of social distancing resulting from the COVID-19 pandemic, from the perspective of the medical student in the last two years of medical school, after the interruption of in-person activities. Method: Study conducted at a medical school in the interior of São Paulo, with students from the last two years of the medical course. This is a qualitative field research, carried out through narratives with thematic content analysis, according to Bardin and Minayo. Results: Eleven narratives were analyzed, seven written by fifth-year students and four by sixth-year students. In them, fear of the pandemic and its consequences, disbelief with the country’s situation and criticism of the behavior of acquaintances were evident. In the academic setting, there was concern about the interruption of practical activities close to the end of the undergraduate course, thoughts about being a medical student on clinical clerkship during the pandemic, with a feeling of incapacity in helping to cope with the health crisis, as well as fear of getting infected or infecting family members. However, the need for rest, reinforcement of family bonds and opportunities for new learning were also reported. Conclusions: In short, the pandemic generated concerns about uncertainties in the social, economic, political and scientific fields, which, added to the moment of these medical students’ education, contributed to difficulties in relation to mental health. However, the period was also evaluated as a positive one, as it provided free time to increase study performance, in addition to the opportunity to carry out extracurricular activities.
