Programming of an educational robot to be applied in STEAM areas

Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do ParanáThe world is increasingly digital. Countries around the world strive to attract and prepare future generations to occupy the positions, where, for the most part, they will focus on Science, Technology, Engineering, Arts and Mathematics (STEAM). An approach already consolidated in the literature is the use of robots applied in education to encourage students to develop essential skills such as critical thinking, problem-solving and computational thinking. This work, linked to the RoboSTEAM project, aims to explore educational robots that can be applied in this context, considering that most approaches use LEGO’s platform, which can sometimes be difficult to access due to its high price. The robot used was the mBot in which it uses the mBlock 5 software to program it, from the MakeBlock Co. Ltd. company, being applied in two educational approaches during the execution of the project in which it is based on challenge based-learning methodology. A methodology for adding sensors to the mBot has been also explored. Finally, evaluations were made about the performance of students who participated in this project

Local Anesthesia

Local anesthesia is a routine procedure in dermatological practice. This chapter deals with the basic principles of pharmacology and pharmacodynamics related to the most commonly used anesthetics in dermatology as well as its side effects, the most common anesthetic solutions, anesthesia techniques, and topical anesthesia

Political Accountability and Misinformation

What are the impacts of misinformation on political accountability? We address this question in a political career concerns framework with belief misspecification. In our model, an incumbent politician of an unknown ability seeks to maximize reelection chances by putting costly effort into the provision of a public good. Citizens agree ex-ante on how to interpret the outcomes of the incumbent's effort. However, some of them disagree on how to interpret other signals. Specifically, some voters incorrectly believe that a confounding signal is informative about the incumbent's ability, while others correctly understand that they are completely uninformative. This misspecification on this signal leads to ex-post disagreement on how successful the incumbent should be in providing the public good to secure a reelection. We consider both an intensive margin and an extensive margin of informational disagreement, that is, (i) how much the beliefs of citizens with learning misspecification differ from the beliefs of citizens with a correct learning model, and (ii) how much misspecified citizens represent in the composition of society. We characterize the impact of informational disagreement on effective accountability (the effort provided by the incumbent in equilibrium). Our analysis not only identifies situations in which misinformation impacts negatively the social contributions of elected governments, but also – perhaps counter-intuitively, situations in which misinformation increases political accountability

Frações do nitrogênio na microbiota de solos do sul do Brasil

The reaction of nitrogen compounds with ninhydrin can be used as an indicator of cytoplasmic materials released from microbial cells killed by fumigation. Total-N, ninhydrin-reactive-N (NR-N), ammonium-N (A-N), and a-amino-N in the microbial biomass of soils from the State of Rio Grande do Sul, Brazil, were determined, in 1996, in 0.5 mol L-1 K2SO4 extracts of fumigated and non-fumigated soils. Total-N varied from 20.3 to 104.4 mg kg-1 and the ninhydrinreactive- N corresponded, in average, to 27% of this. The ninhydrin-reactive-N was made up of 67% ammonium-N and 33% aminoacids with the amino group at the a-carbon position. It was concluded that colorimetric analysis of NR-N and A-N may be used as a direct measure of microbial N in soil. This simple and rapid procedure is adequate for routine analyses.A reação de compostos nitrogenados com a ninhidrina pode ser utilizada como parâmetro indicador dos produtos citoplásmicos oriundos da lise de células microbianas mortas pela fumigação. Com base nessa assertiva, realizou-se o presente trabalho, em 1996, com o objetivo de avaliar as concentrações de N-total, N-reativo com ninhidrina (NR-N), N-amônio (A-N) e N-a-amino presentes na biomassa microbiana de solos do Rio Grande do Sul. A partir da extração com K2SO4 0,5 mol L-1 de amostras provenientes de solos fumigados e não fumigados, determinaram-se as frações nitrogenadas presentes na biomassa. Constatouse que a quantidade do N-total presente na biomassa variou de 20,3 a 104,4 mg kg-1 de solo, sendo a fração microbiana reativa com a ninhidrina correspondente a 27% desses valores, em média. Dois terços dessa fração eram constituídos de nitrogênio na forma de amôniomicrobiano e um terço na forma de aminoácidos contendo o radical amino no carbono a. É possível utilizar a análise colorimétrica do NR-N e do A-N para a quantificação do N-microbiano do solo. Tais procedimentos são rápidos, simples e aplicáveis em análises de rotina

Prototyping of a low-cost stroboscope to be applied in condition maintenance: an open hardware and software approach

This paper aims to develop a low-cost stroboscope, which consists of an optical equipment capable of generating flashes of light at different frequencies, allowing to measure the rotation velocity of machines and contributing to maintenance processes in the industry. This device is based on the stroboscopic effect, a visual event that occurs when a continuous movement is presented by a series of samples, generated by flashes of light. When the frequency of the rotation movement is the same frequency of light pulses, the process will appear stationary. Based on the high cost of the commercial stroboscopes, it was developed a stroboscope prototype based on the Arduino platform, LED technology and 3D printing with an open hardware and software. The final prototype went through calibration and validation processes, achieving a performance very similar to a commercial instrument.This work has been supported by FCT - Fundação para a Ciência e Tecnologia with in the Project Scope: UIDB/05757/2020info:eu-repo/semantics/publishedVersio

Formação Moral e Ética nos Cursos de Graduação

Baseado nos conceitos de La Taille (2006) em que a ética contempla a moral, mas também envolve o projeto de vida e a trajetória profissional, o presente estudo buscou analisar as reflexões sobre o sucesso profissional dentro de um curso de graduação em Administração. Investigando o projeto de vida, as concepções da universidade sobre o sucesso profissional e seus desdobramentos, descobriu-se que os alunos podem ou não incluir a preocupação com o outro na sua visão de sucesso profissional, mas eles entendem a necessidade de um esforço tanto da instituição como do corpo discente para realizar essa discussão no âmbito universitário.Based on the concepts of La Taille (2006) in which ethics includes moral, but also involves the design of life and the professional trajectory, this study sought to analyze the reflections on professional success within an undergraduate business course.

It was discovered that students may or may not include concern for others in their professional vision of success, but they understand the need for an effort of both the institution and the student body to conduct this discussion in the Universit
