Projects with the industry for the development of professional competences in industrial engineering and management

Training engineering students has been evolving towards the development of professional competences, both technical and transversal. These competences will enable new engineers to apply learning resources in professional contexts with greater efficacy. Thus, these engineers will be closer to the needs of industry. A learning methodology that has been used in these contexts is Project Based Learning (PBL). This paper presents a learning process based on PBL concepts, in which five teams of 5 to 7 students of Industrial Engineering and Management from the University of Minho, Portugal, developed projects in interaction with companies during a semester. This project is supported by 5 courses of the 7th semester: Organization of Production Systems, Information Systems for Production, Integrated Production Management, Ergonomic Study of Workplaces and Simulation. The objective of the students’ project is to make the analysis and present proposals for improvement of a part of the production system of a company. With the support of teachers, students should manage the interaction with an industrial company under the established partnership and present suggestions for improvements to their production system, considering contributions from the 5 courses of the semester. The aim of this paper is to describe the operational model of this PBL process, evaluate the results in terms of students’ learning and in terms of the perception of industry, and finally make proposals for improving the model. The evaluation of learning outcomes is based on the analysis of students’ project results, a questionnaire and a closing workshop of the project with students. The evaluation of the perception of industry partners is achieved using informal interviews with company representatives. The evaluation process shows that, from the participants’ perceptions, students have developed the competences that are expected and, in general, the teams are motivated by the outcome of their projects. They referred that there should exist better mechanisms of differentiation of individual classifications within the team. From the point of view of industry, the results are considered good, but there is a tendency to propose a greater focus on the objectives and results of the project. Considering these results, a change to the model is proposed, in order to increase the direction of the project. The proposal organizes the project into two very distinct phases: (1) analysis and diagnosis phase; (2) improvement phase. This change would explore the contents and competences expected of all courses during the analysis and diagnosis phase, and in second phase, the project would focus on developing specific solutions for the enterprise

The importance of neighborhood ecological assets in community dwelling old people aging outcomes: A study in Northern Portugal

Human development is a bidirectional, person-context relational process, but scarce evidence is available about the relation between the individual variability across the life-span and the neighborhood ecological assets. Therefore, it is important that research focus not only on personal characteristics but on ecological assets as well. This way this study aims to analyze the association between neighborhood ecological assets categorized into four dimensions: human, physical or institutional, social or collective activity, accessibility, and the individual functioning. A 3% sample of residents aged 65 years and older in two downtown and three uptown parishes stratified by age and sex was interviewed at home using a protocol that included the Portuguese version of the Barthel Index in basic activities of daily living (BADL), the Lawton Instrumental Activities of Daily Living Scale (IADL), the Mini Mental State Examination (MMSE), and the Geriatric Depression Scale-15 items (GDS) for evaluating functionality, cognitive performance, and depression. The 162 participants were aged on average 75 years (sd = 7.0), 54% were women and 90% had less than 7 years of education. The majority of participants were independent in BADL (M = 90; sd = 17.7) and moderately dependent in IADL (M = 13, sd = 6.0), 20% showed cognitive impairment and a mean score of 8 (sd = 2.1) in GDS-15. After controlling for the effect of socio-demographic characteristics, functionality, and cognitive performance decreases in persons with worst outdoor mobility. On the other hand depressive symptoms are less common as the number of recreation opportunities, namely associative groups (cultural, educative, professional), increases. These results suggest that aging policies and practices must be ecologically embedded.E51F-89A1-B769 | Carla FariaN/

Fatores críticos num processo de Aprendizagem Baseada em Projetos : perceções de estudantes de 1º ano de Engenharia

This paper presents the students’ perceptions about the interdisciplinary project implemented in the first year of the Integrated Master’s degree in Industrial Engineering and Management (IEM) at the University of Minho, Guimarães, Portugal. This project was supported by four curricular units (UCs): General Chemistry (GC); Calculus (C); Introduction to Industrial Engineering (IIE) and Computer Programming 1 (PC1). In order to collect data on the perceptions of students regarding their participation and motivation on 2011/2012 edition, a questionnaire with 46 closed items and 3 open questions was developed and applied to 35 students and the results discussed on a final workshop. Based on the results of the research, the final workshop shows that the students recognize the benefits of Project Based Learning (PBL) as a learning methodology, its contribution and motivation to development of competences and skills for future career and the importance of teamwork. However, the findings showed that the roles of teachers and tutors must be reviewed as well as the grade’s weight of project related with UCs. Furthermore, students also pointed out some additional constraints during the project, namely: time required for the project; the integration of UCs’ contents in the project and the effort put in the project and its impact in final grades

Meningococcal disease: epidemiology and control of secondary cases

Aspectos epidemiológicos da doença meningocócica registrados a partir da segunda metade da década de 80 impulsionaram as autoridades de saúde pública a discutirem as medidas de controle disponíveis. A ocorrência da doença entre adolescentes e o registro de surtos envolvendo escolas são os dois pontos que mais pressionaram uma revisão das medidas de controle disponíveis. O uso das vacinas antimeningocócicas polissacarídeas e as recomendações para o controle de surtos localizados (clusters) são outros aspectos que mereceram atenção recentemente. Objetivou, assim, apresentar um panorama atual de alguns aspectos da epidemiologia e do controle dos casos secundários da doença meningocócica.Epidemiological features of meningococcal disease described as from the second half of the 80's inclusive, have motivated a revision of current guidelines for sporadic disease and outbreak control. The increase of disease among teenagers and linked cases involving schools are the two most significant aspects that have prompted the revision of control measures. Vaccination routines and advice for the disease management of clusters are also relevant features recently revised. This present paper describes the management and some epidemiological features of secondary cases

Prevalência de programas de promoção da saúde em unidades básicas de saúde no Brasil

OBJECTIVE Assessment of prevalence of health promotion programs in primary health care units within Brazil’s health system. METHODS We conducted a cross-sectional descriptive study based on telephone interviews with managers of primary care units. Of a total 42,486 primary health care units listed in the Brazilian Unified Health System directory, 1,600 were randomly selected. Care units from all five Brazilian macroregions were selected proportionally to the number of units in each region. We examined whether any of the following five different types of health promotion programs was available: physical activity; smoking cessation; cessation of alcohol and illicit drug use; healthy eating; and healthy environment. Information was collected on the kinds of activities offered and the status of implementation of the Family Health Strategy at the units. RESULTS Most units (62.0%) reported having in place three health promotion programs or more and only 3.0% reported having none. Healthy environment (77.0%) and healthy eating (72.0%) programs were the most widely available; smoking and alcohol use cessation were reported in 54.0% and 42.0% of the units. Physical activity programs were offered in less than 40.0% of the units and their availability varied greatly nationwide, from 51.0% in the Southeast to as low as 21.0% in the North. The Family Health Strategy was implemented in most units (61.0%); however, they did not offer more health promotion programs than others did. CONCLUSIONS Our study showed that most primary care units have in place health promotion programs. Public policies are needed to strengthen primary care services and improve training of health providers to meet the goals of the agenda for health promotion in Brazil.OBJETIVO Estimar a prevalência de programas de promoção da saúde nas unidades básicas de saúde no Brasil.

A promoção de atividade física foi referida em menos de 40,0% das unidades e teve grande variação regional, com prevalência de 51,0% nas unidades do Sudeste e apenas 21,0% nas do Norte. A maioria das unidades de saúde (61,0%) oferecia Estratégia de Saúde da Família, porém não foi verificada maior prevalência de programas de promoção da saúde nessas unidades em relação às outras. CONCLUSÕES Este estudo mostrou que programas de promoção da saúde estão presentes na maioria das unidades básicas de saúde. Políticas públicas devem fortalecer a infraestrutura das unidades básicas de saúde e melhorar a capacitação dos trabalhadores de saúde para executar adequadamente a agenda de promoção de saúde do governo brasileiro

Outcomes of Decompressive Surgery for Patients With Severe Cerebral Venous Thrombosis: DECOMPRESS2 Observational Study

BACKGROUND: Decompressive neurosurgery is recommended for patients with cerebral venous thrombosis (CVT) who have large parenchymal lesions and impending brain herniation. This recommendation is based on limited evidence. We report long-term outcomes of patients with CVT treated by decompressive neurosurgery in an international cohort. METHODS: DECOMPRESS2 (Decompressive Surgery for Patients With Cerebral Venous Thrombosis, Part 2) was a prospective, international cohort study. Consecutive patients with CVT treated by decompressive neurosurgery were evaluated at admission, discharge, 6 months, and 12 months. The primary outcome was death or severe disability (modified Rankin Scale scores, 5-6) at 12 months. The secondary outcomes included patient and caregiver opinions on the benefits of surgery. The association between baseline variables before surgery and the primary outcome was assessed by multivariable logistic regression. RESULTS: A total of 118 patients (80 women; median age, 38 years) were included from 15 centers in 10 countries from December 2011 to December 2019. Surgery (115 craniectomies and 37 hematoma evacuations) was performed within a median of 1 day after diagnosis. At last assessment before surgery, 68 (57.6%) patients were comatose, fixed dilated pupils were found unilaterally in 27 (22.9%) and bilaterally in 9 (7.6%). Twelve-month follow-up data were available for 113 (95.8%) patients. Forty-six (39%) patients were dead or severely disabled (modified Rankin Scale scores, 5-6), of whom 40 (33.9%) patients had died. Forty-two (35.6%) patients were independent (modified Rankin Scale scores, 0-2). Coma (odds ratio, 2.39 [95% CI, 1.03-5.56]) and fixed dilated pupil (odds ratio, 2.22 [95% CI, 0.90-4.92]) were predictors of death or severe disability. Of the survivors, 56 (78.9%) patients and 61 (87.1%) caregivers expressed a positive opinion on surgery. CONCLUSIONS: Two-thirds of patients with severe CVT were alive and more than one-third were independent 1 year after decompressive surgery. Among survivors, surgery was judged as worthwhile by 4 out of 5 patients and caregivers. These results support the recommendation to perform decompressive neurosurgery in patients with CVT with impending brain herniation

A Single Dose of a Hybrid hAdV5-Based Anti-COVID-19 Vaccine Induces a Long-Lasting Immune Response and Broad Coverage against VOC

Most approved vaccines against COVID-19 have to be administered in a prime/boost regimen. We engineered a novel vaccine based on a chimeric human adenovirus 5 (hAdV5) vector. The vaccine (named CoroVaxG.3) is based on three pillars: (i) high expression of Spike to enhance its immunodominance by using a potent promoter and an mRNA stabilizer; (ii) enhanced infection of muscle and dendritic cells by replacing the fiber knob domain of hAdV5 by hAdV3; (iii) use of Spike stabilized in a prefusion conformation. The transduction with CoroVaxG.3-expressing Spike (D614G) dramatically enhanced the Spike expression in human muscle cells, monocytes and dendritic cells compared to CoroVaxG.5 that expressed the native fiber knob domain. A single dose of CoroVaxG.3 induced a potent humoral immunity with a balanced Th1/Th2 ratio and potent T-cell immunity, both lasting for at least 5 months. Sera from CoroVaxG.3-vaccinated mice was able to neutralize pseudoviruses expressing B.1 (wild type D614G), B.1.117 (alpha), P.1 (gamma) and B.1.617.2 (delta) Spikes, as well as an authentic P.1 SARS-CoV-2 isolate. Neutralizing antibodies did not wane even after 5 months, making this kind of vaccine a likely candidate to enter clinical trials.Fil: López, M. Verónica.

Dendritic Cell Subtypes from Lymph Nodes and Blood Show Contrasted Gene Expression Programs upon Bluetongue Virus Infection

Chantier qualité GAHuman and animal hemorrhagic viruses initially target dendritic cells (DCs). It has been proposed, but not documented, that both plasmacytoid DCs (pDCs) and conventional DCs (cDCs) may participate in the cytokine storm encountered in these infections. In order to evaluate the contribution of DCs in hemorrhagic virus pathogenesis, we performed a genome-wide expression analysis during infection by Bluetongue virus (BTV), a double-stranded RNA virus that induces hemorrhagic fever in sheep and initially infects cDCs. Both pDCs and cDCs accumulated in regional lymph nodes and spleen during BTV infection. The gene response profiles were performed at the onset of the disease and markedly differed with the DC subtypes and their lymphoid organ location. An integrative knowledge-based analysis revealed that blood pDCs displayed a gene signature related to activation of systemic inflammation and permeability of vasculature. In contrast, the gene profile of pDCs and cDCs in lymph nodes was oriented to inhibition of inflammation, whereas spleen cDCs did not show a clear functional orientation. These analyses indicate that tissue location and DC subtype affect the functional gene expression program induced by BTV and suggest the involvement of blood pDCs in the inflammation and plasma leakage/hemorrhage during BTV infection in the real natural host of the virus. These findings open the avenue to target DCs for therapeutic interventions in viral hemorrhagic diseases

Resolving forward-reverse logistics multi-period model using evolutionary algorithms

© 2016 Elsevier Ltd In the changing competitive landscape and with growing environmental awareness, reverse logistics issues have become prominent in manufacturing organizations. As a result there is an increasing focus on green aspects of the supply chain to reduce environmental impacts and ensure environmental efficiency. This is largely driven by changes made in government rules and regulations with which organizations must comply in order to successfully operate in different regions of the world. Therefore, manufacturing organizations are striving hard to implement environmentally efficient supply chains while simultaneously maximizing their profit to compete in the market. To address the issue, this research studies a forward-reverse logistics model. This paper puts forward a model of a multi-period, multi-echelon, vehicle routing, forward-reverse logistics system. The network considered in the model assumes a fixed number of suppliers, facilities, distributors, customer zones, disassembly locations, re-distributors and second customer zones. The demand levels at customer zones are assumed to be deterministic. The objective of the paper is to maximize the total expected profit and also to obtain an efficient route for the vehicle corresponding to an optimal/near optimal solution. The proposed model is resolved using Artificial Immune System (AIS) and Particle Swarm Optimization (PSO) algorithms. The findings show that for the considered model, AIS works better than the PSO. This information is important for a manufacturing organization engaged in reverse logistics programs and in running units efficiently. This paper also contributes to the limited literature on reverse logistics that considers costs and profit as well as vehicle route management

A social and ecological assessment of tropical land uses at multiple scales: the Sustainable amazon network

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers three advantages for addressing land-use sustainability problems: (i) the collection of synchronized and co-located ecological and socioeconomic data across broad gradients of past and present human use; (ii) a nested sampling design to aid comparison of ecological and socioeconomic conditions associated with different land uses across local, landscape and regional scales; and (iii) a strong engagement with a wide variety of actors and non-research institutions. Here, we elaborate on these key features, and identify the ways in which RAS can help in highlighting those problems in most urgent need of attention, and in guiding improvements in land-use sustainability in Amazonia and elsewhere in the tropics. We also discuss some of the practical lessons, limitations and realities faced during the development of the RAS initiative so far
