ONTOLOGIA E MEDIAÇÃO: KANT, PEIRCE E JUNG

The origins of this text are a result from the reflections accomplished in group, during the development of the disciplines “Epistemology and Science” and “Semiotics, Aesthetics and Knowledge”, both of the Post-Graduate Program in Knowledge Engineering and Management - UFSC. The main approached subject is the intuition in the knowledge origin, as it was proposed firstly in the categories presented in the "Critical of Pure Reason" of Immanuel Kant, which had questioned the cartesianism. Later, the Kantian categories were also criticized by Charles S. Peirce, that was author of a series of seven questions on the theme in study. Those questions are presented and discussed to follow, in accordance with the Peirce’s thought and, also, with Carl Gustav Jung ideas. The convergence point that justifies the confrontation of the Peirce and Jung ideas is the symbol concept that was adopted and particularly developed by the two thinkers.As origens deste texto decorrem das reflexões realizadas em grupo, durante o desenvolvimento das disciplinas “Epistemologia e Ciência” e “Semiótica, Estética e Conhecimento”, ambas do Programa de Pós-Graduação em Engenharia e Gestão do Conhecimento - UFSC. A principal questão abordada é a intuição na origem do conhecimento, como foi primeiramente proposta nas categorias apresentadas na “Crítica da Razão Pura” de Immanuel Kant, as quais questionaram o cartesianismo. Posteriormente, as categorias kantianas também foram criticadas por Charles S. Peirce, que foi autor de uma série de sete questões sobre o tema em estudo. Essas questões são apresentadas e discutidas a seguir, de acordo com o pensamento de Peirce e, também, com as idéias de Carl Gustav Jung. O ponto de convergência que justifica o confronto das idéias de Peirce e Jung é o conceito de símbolo que foi adotado e particularmente desenvolvido pelos dois pensadores

Evaluation of the magnetic permeability for the microstructural characterization of a duplex stainless steel

Non-Destructive Testing has been commonly used to assess the presence of discontinuities that may affect the integrity of materials in service. In this study, a Hall effect sensor is used in a methodology developed to study in a non-destructive manner the microstructural variations of a material that occur due to the single-phase decomposition. The material selected was the UNS S31803 duplex stainless steel, particularly due to its behavior under temperatures below 525 °C. Measurements of magnetic permeability based on Hall voltage values were performed as well as hardness measurements and X-ray diffraction studies. The results confirm that the magnetic permeability can be used to successfully track the formation of α' phase from α phase in a duplex stainless steel

REFLEXÕES SOBRE MEMÓRIA DE TRABALHO E MEMÓRIA ORGANIZACIONAL NO ÂMBITO DA GESTÃO DO CONHECIMENTO

Este artigo tem por objetivo apresentar e desenvolver algumas reflexões sobre as relações entre memória de trabalho (MT) e memória organizacional (MO) na perspectiva da gestão do conhecimento (GC), levandose em conta os conceitos de criação, estruturação e disseminação do conhecimento. Partindo de abordagens teóricas sobre GC, resgatam-se os conceitos de memória individual especialmente o de memória de trabalho para buscar compreender como a MT, no plano pessoal, possibilita a construção da MO, que é decorrência dos processos de aprendizagem organizacional.Palavras-chave: gestão do conhecimento; aprendizagem organizacional; memória de trabalho (MT); memória organizacional (MO)

ASPECTOS EPIDEMIOLÓGICOS E PREVALÊNCIA DE ENTEROPARASITOSES EM CRIANÇAS DO BAIRRO JAMBEIRO, SÃO LUÍS, MA

A carência de condições básicas de higiene e saneamento, aliadas à falta de limpeza dos reservatórios de água e a não utilização de água fltrada ou fervida, intensifcam a ocorrência de problemas de saúde pública. Com o intuito de contribuir para a conscientização da população acerca dos problemas de saúde decorrentes da contaminação da água, realizou-se no Bairro do Jambeiro, localizado nas mediações da Universidade Federal do Maranhão, um projeto interdisciplinar que visou, pela divulgação dos dados da pesquisa científca, avaliar a água utilizada pelos moradores através de análise físico-química, microbiológica e parasitológica, de modo que os resultados permitissem a conscientização, através de atividades educacionais dos moradores. Os resultados endossam a precariedade de condições sanitárias encontradas nessa comunidade. Os poços, as torneiras e o córrego apresentam níveis de contaminação acima do recomendável pela Resolução CONAMA e ANVISA, sendo, portanto, impróprias para o consumo. Os exames parasitológicos revelaram alta prevalência (91%) de enteroparasitoses nas crianças. A partir desses resultados os integrantes do projeto e seus parceiros realizaram palestras destinadas à comunidade sobre os meios de tratamento da água, biologia dos parasitas e medidas profláticas das principais verminoses. Concomitante, ocorreu a entrega e esclarecimentos dos laudos da análise físico-química, microbiológica e parasitológica, onde houve a distribuição de remédios às crianças que estavam infectadas.Descritores:  Enteroparasitos; Epidemiologia; Prevalência.Abstract: The lack of basic conditions hygiene and sanitation, allied to grubbiness of water reservoirs and no use of fltered or boiled water, enhance the occurrence of health public problems. With the aim of contribute to awareness of the population about the health problems resulting from the water contamination, was held in the District of the Jambeiro, located near the Federal University of Maranhão, an interdisciplinary project the aimed, by disclosure of scientifc research, to evaluate the water used by population through physico-chemical, microbiological and parasitological analyses, so that the results allow awareness through educational activities of population. The results comproved the precarious sanitary conditions found in this community. The level contamination of the wells, taps and stream is higher than recommended by Resolution CONAMA and ANVISA, therefore, unft for consumption. The parasitological revealed a high prevalence (91%) of intestinal parasites in children. Based on these results the members of the project and its partners held talks for the community about the water treatment, biology of parasites and worms and of the main prophylactic measures. Concomitantly, there was the delivery and clarifcation of reports of physico-chemical, microbiological and parasitological, where there was the distribution of drugs to children who were infected.Descriptors: Enteroparasites; Epidemiology; Prevalence

International multicenter observational study on assessment of ventilatory management during general anaesthesia for robotic surgery and its effects on postoperative pulmonary complication (AVATaR) : study protocol and statistical analysis plan

Introduction: Robotic-assisted surgery (RAS) has emerged as an alternative minimally invasive surgical option. Despite its growing applicability, the frequent need for pneumoperitoneum and Trendelenburg position could significantly affect respiratory mechanics during RAS. AVATaR is an international multicenter observational study aiming to assess the incidence of postoperative pulmonary complications (PPC), to characterise current practices of mechanical ventilation (MV) and to evaluate a possible association between ventilatory parameters and PPC in patients undergoing RAS. Methods and analysis: AVATaR is an observational study of surgical patients undergoing MV for general anaesthesia for RAS. The primary outcome is the incidence of PPC during the first five postoperative days. Secondary outcomes include practice of MV, effect of surgical positioning on MV, effect of MV on clinical outcome and intraoperative complications. Ethics and dissemination: This study was approved by the Institutional Review Board of the Hospital Israelita Albert Einstein. The study results will be published in peer-reviewed journals and disseminated at international conferences. Trial registration number: NCT02989415; Pre-results

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
