Pensar no comportamento humano, dentro das empresas, foi o objeto de estudo, pois se é de extrema importância em qualquer área da vida, não seria diferente dentro das organizações. Saber interagir com as outras pessoas, respeitá-las, ter o bom senso para saber a hora de falar e a hora de ouvir. O objetivo do estudo foi entender o comportamento humano dentro das empresas, no município de Hortolândia e região, verificando a percepção dos colaboradores quanto à cultura organizacional, motivação, liderança e percepção. Este estudo se constituiu de uma pesquisa elaborada pelos próprios pesquisadores, aplicada a 61 funcionários, tendo o processo de coleta de dados sido feito por meio da aplicação de questionário a uma amostra definida e, por fim, o processo de análise dos dados se deu por tabulação, transferência dos dados para um software estatístico, para interpretação pela análise descritiva. Foi aplicado um questionário formado por 10 questões pinçadas, pelos pesquisadores, dos questionários: "70 perguntas para se fazer pesquisa interna na empresa" e "Pesquisa de satisfação interna". Esse questionário visou identificar o comportamento humano nos construtos liderança (itens 1, 2 e 7), motivação (itens 3, 4 e 6), percepção (itens 5, 9 e 10) e cultura organizacional (Item 8). Observados os resultados, pôde-se concluir que as empresas precisam se preocupar com a totalidade dos funcionários em todos os aspectos pesquisados. A liderança, cultura organizacional, motivação e percepção organizacional influenciam muito no desempenho dos empregados, as pessoas são diferentes entre si, portanto, cabe à empresa conhecer o perfil dos seus funcionários para saber como entusiasmá-los.

O esgotamento de recursos naturais é um assunto recorrente e uma das formas de recuperar os recursos é através do aproveitamento de resíduos no final do ciclo de vida dos produtos. Essa prática, no Brasil, tem recebido destaque com a Política Nacional dos Resíduos Sólidos (PNRS), que incentiva as organizações a se esforçarem para atingir indicadores sustentáveis. Nesse contexto, o campus de Sorocaba da Universidade Federal de São Carlos tem se dedicado a desenvolver projetos de logística reversa, reaproveitamento de materiais e reciclagem de resíduos de equipamentos eletroeletrônicos (REEEs). O objetivo desse trabalho foi avaliar e analisar os resultados da utilização de um ponto de coleta de REEEs através de uma Survey. O projeto foi desenvolvido em parceria com um centro de inovação de uma empresa de Sorocaba, que realiza a reciclagem de REEEs coletados. Como resultados, o estudo apresentou a importância da manutenção física do ponto de coleta, da realização de campanhas de divulgação do ponto de coleta para fomentar a conscientização ambiental da comunidade e, também, apontou a sazonalidade dos materiais coletados. Adicionalmente, revelou o comportamento do consumidor, no sentido de colaboração no descarte adequado de REEE, quando há disponibilidade de um ponto de coleta específico.
Background The healthcare system can be understood as the dynamic result of the interaction of hospitals, patients, providers, and government configuring a complex network of reciprocal influences. In order to better understand such a complex system, the analysis must include characteristics that are feasible to be studied in order to redesign its functioning. The analysis of the emergent patterns of pregnant women flows crossing municipal borders for birth-related hospitalizations in a region of São Paulo, Brazil, allowed to examine the functionality of the regional division in the state using a complex systems approach and to propose answers to the dilemma of concentration vs. distribution of maternal care regional services in the context of the Brazilian Unified Health System (SUS). Methods Cross-sectional research of the areas of influence of hospitals using spatial interaction methods, recording the points of origin and destination of the patients and exploring the emergent patterns of displacement. Results The resulting functional region is broader than the limits established in the legal provisions, verifying that 85% of patients move to hospitals with high technology to perform normal deliveries and cesarean sections. The region has high independence rates and behaves as a "service exporter." Patients going to centrally located hospitals travel twice as long as patients who receive care in other municipalities even when the patients' conditions do not demand technologically sophisticated services. The effects of regulation and the agents' preferences reinforce the tendency to refer patients to centrally located hospitals. Conclusions Displacement of patients during delivery may affect indicators of maternal and perinatal health. The emergent pattern of movements allowed examining the contradiction between wider deployments of services versus concentration of highly specialized resources in a few places. The study shows the potential of this type of analysis applied to other type of patients' flows, such as cancer or specialized surgery, as tools to guide the regionalization of the Brazilian Health System.

Due to the accelerated urbanization process, Brazilian cities grow with little or no urban planning, and when it is present, climate issues are generally not considered, especially in small and medium-sized cities. Thus, the present research had as objective to evaluate a method of application of climatic knowledge throughout the process of revision of the Municipal Master Plan of Cáceres-MT. The methodology used to evaluate climatic variables is based on data provided by INMET and mobile transect measurements within the urban perimeter. Through this, it was possible to know the behavior of air temperature, relative humidity, precipitation, wind speed and direction during the dry season and also over the years. Thus, through mobile transect measurements, a temperature difference between the analyzed points of 1.2ºC in the morning period and 1.9ºC in the afternoon and evening periods could be observed. As for humidity, a difference of 10% was observed in the morning period and 9% in the afternoon and evening periods. Therefore, through the phases of the Master Plan (diagnosis, prognosis and public management), proposals have been prepared to mitigate the identified harmful effects of the most affected areas in relation to the climate, and thus, contribute to the review process of the Municipal Master Plan of Cáceres-MT with climatic knowledge.

Background: The All Patient-Refined Diagnosis-Related Groups (APR-DRGs) system has adjusted the basic DRG structure by incorporating four severity of illness (SOI) levels, which are used for determining hospital payment. A comprehensive report of all relevant diagnoses, namely the patient's underlying co-morbidities, is a key factor for ensuring that SOI determination will be adequate. Objective: In this study, we aimed to characterise the individual impact of co-morbidities on APR-DRG classification and hospital funding in the context of respiratory and cardiovascular diseases. Methods: Using 6 years of coded clinical data from a nationwide Portuguese inpatient database and support vector machine (SVM) models, we simulated and explored the APR-DRG classification to understand its response to individual removal of Charlson and Elixhauser co-morbidities. We also estimated the amount of hospital payments that could have been lost when co-morbidities are under-reported. Results: In our scenario, most Charlson and Elixhauser co-morbidities did considerably influence SOI determination but had little impact on base APR-DRG assignment. The degree of influence of each co-morbidity on SOI was, however, quite specific to the base APR-DRG. Under-coding of all studied co-morbidities led to losses in hospital payments. Furthermore, our results based on the SVM models were consistent with overall APR-DRG grouping logics. Conclusion and implications: Comprehensive reporting of pre-existing or newly acquired co-morbidities should be encouraged in hospitals as they have an important influence on SOI assignment and thus on hospital funding. Furthermore, we recommend that future guidelines to be used by medical coders should include specific rules concerning coding of co-morbidities.

IntroductionBusiness process management has gained importance in organizations for providing improved productivity and cost reduction, with process modeling being the central role. Usually, with reduced resources, the health area can benefit from good management of its processes.ObjectiveTo identify proposals for improvements in the process of outpatient care of children and adolescents in a tertiary‐level—the most specialized and complex—pediatric hospital.MethodsA bibliographic survey on the subject and a case study with in loco observation of the processes with semistructured interviews with the professionals involved were carried out. Alpha Hospital was chosen for this study, and the modeling of the process was performed using Business Process Model and Notation.ResultsTwelve relevant articles were identified. The "AS‐IS" model of the process was obtained as a result and presents the existing 4 subprocesses (patient reception, preconsultation, consultation, and postconsultation). Specifically, the following improvement opportunities were identified: (a) process monitoring through indicators; (b) adequacy of the information system; (c) creation of service evaluation mechanisms; and (d) definition and application of training sessions for whenever a new professional begins working in a specific sector. The problem with the waiting time for patient care was also identified, but with no obvious solution; further studies should be carried to solve the problem.ConclusionThe use of the business process modeling approach and process analysis allowed the hospital team awareness of the process and the identification of an improved set that can be helpful to Alpha Hospital or be used by other hospitals.

Introduction: The Brazilian Policy for Comprehensive Care for People with Rare Diseases (BPCCPRD) was published in 2014, accrediting several reference centers and incorporating many genetic tests for the diagnosis of rare diseases (RDs). The Brazilian Network of Rare Diseases (RARAS) comprises more than 40 institutions that offer diagnosis and treatment for RDs in Brazil. This network includes Reference Services for Rare Diseases (RDRS), Reference Services for Newborn Screening (NSRS), and University Hospitals distributed in all Brazilian regions. Objective: The aim of the study was to map the availability and distribution of the BPCCPRD diagnostic procedures in the Brazilian Unified Health System through RARAS. Method: Data were collected through a questionnaire on the Research Electronic Data Capture platform, with 22 questions regarding the availability of procedures. Thirty-seven coordinators from RARAS participating centers received the questionnaire link for participation by email from August/2020 to March/2021. All participating institutions ethically approved this project. Results: Of the 37 institutions, 23 (62.16%) offered cytogenetic tests, 20 (54.05%) offered molecular procedures, and 22 (59.46%) offered inborn errors of metabolism diagnostic tests. The Southern blot analysis, enzyme assays on cultured tissue and urinary organic acid tests had the highest outsourcing rate. On the other hand, the procedures most frequently performed on-site were bone marrow karyotype and long-term cultured karyotype. It was observed that 10 of the 37 centers (27%) did not provide access to investigated procedures (on-site or outsourced). The North and Midwest regions stood out in terms of the unavailability of such techniques in at least 40% of the evaluated institutions. Discussion and Conclusion: This study reveals large discrepancies in the supply of diagnostic procedures in the Brazilian territory. Moreover, there is a broad collaboration between services through the outsourcing of multiple diagnostic techniques to address this issue. Finally, this work corroborates the importance of mapping services for the diagnosis and treatment of individuals with RDs to propose actions for the better supply and distribution of these procedures.

Abstract INTRODUCTION Five months after the first confirmed case of COVID-19 in Brazil, the country has the second highest number of cases in the world. Without any scientifically proven drug or vaccine available combined with COVID-19's high transmissivity, slowing down the spread of the infection is a challenge. In an attempt to save the economy, the Brazilian government is slowly beginning to allow non-essential services to reopen for in-person customers. METHODS: In this study, we analyze, based on data analysis and statistics, how other countries evolve and under which conditions they decided to resume normal activity. In addition, due to the heterogeneity of Brazil, we explore Brazilian data of COVID-19 from the State Health Secretaries to evaluate the situation of the pandemic within the states. RESULTS: Results show that while other countries have flattened their curves and present low numbers of active cases, Brazil continues to see an increase in COVID-19 patients. Furthermore, a number of important states are easing restrictions despite a high percentage of confirmed cases. CONCLUSIONS: All analyses show that Brazil is not ready for reopening, and the premature easing of restrictions may increase the number of COVID-19-related deaths and cause the collapse of the public health system.
