Os desafios da qualificação profissional pós-secundária não-superior (nível 4) para a inovação empresarial no contexto da União Europeia e dos países da OCDE

A maioria das nações mais desenvolvidas deve, em larga medida, a sua prosperidade à produtividade da sua força de trabalho. Esta produtividade relaciona-se, fundamentalmente, com dois aspectos essenciais. Por um lado, com o nível e adequação das qualificações e competências da população activa, as quais permitem desenvolver o empreendedorismo e criar riqueza e, por outro, com a qualidade e grau de sofisticação dos equipamentos, tecnologias, modelos de organização e sistemas de gestão de que as empresas dispõem. Nesta comunicação, elaborada por convite para apresentação na sessão comemorativa do 20º aniversário da AFTEM, no Porto, após a contextualização das exigências do mercado de trabalho em resultado da inovação empresarial e da emergência das economias baseadas no conhecimento, apresentam-se alguns estudos recentemente concluídos em diversos países e regiões da OCDE, nomeadamente, Austrália, Irlanda, Reino Unido e Escócia – nos quais se foca a necessidade de incrementar o nível de qualificações para responder às necessidades do tecido produtivo por forma a manter a competitividade da indústria e serviços desses países e regiões à escala global; em particular realça-se a importância de se aumentar a percentagem de população activa com nível 4 de qualificação profissional. Aborda-se, ainda, a situação da formação pós secundária não superior em Portugal (nível 4). Conclui-se, formulando algumas recomendações em termos de estratégias e de trabalho futuro com vista a dinamizar as oportunidades de qualificação de nível 4, em estreita articulação com as empresas, como forma de o tecido produtivo nacional dispor de níveis de qualificação de recursos humanos que permitam a mobilidade para novas actividades com maior valor acrescentado e, por esta via, atingir níveis de rentabilidade semelhante à dos restantes estados membros da UE e de outros países da OCDE.

The active mathematics project at ISCAP

This paper summarizes a project that is contributing to a change in the way of teaching and learning Mathematics. Mathematics is a subject of the Accounting and Administration course. In this subject we teach: Functions and Algebra. The aim is that the students understand the basic concepts and is able to apply them in other issues, when possible, establishing a bridge between the issues that they have studied and their application in Accounting. As from this year, the Accounting course falls under in Bologna Process. The teacher and the student roles have changed. The time for theoretical and practical classes has been reduced, so it was necessary to modify the way of teaching and learning. In the theoretical classes we use systems of multimedia projection to present the concepts, and in the practical classes we solve exercises. To supplement our theoretical and practical classes we have developed an active mathematics project called MatActiva based on the Moodle platform offered by PAOL - Projecto de Apoio Online (Online Support Project). In the last versions of Moodle, it is possible use the TeX language to create math questions. Using this tool we created a set of interactive materials. With the creation of this new project we wanted to take advantage already obtained results with the previous experiences, giving to the students opportunities to complement their study in Mathematics. One of the great objectives is to motivate students, encourage them to overcome theirs difficulties through an auto-study, giving them more confidence and the opportunity to seeing others perspectives of the mathematics subjects. In the MatActiva project the students have a big collection of information about the way of the subject works, which includes the objectives, the program, recommended bibliography, evaluation method and summaries. It works as material support for the practical and theoretical classes, the slides of the theoretical classes are available, the sheets with exercises for the students to do in the classroom and complementary exercises, as well as the exams of previous years. Students can also do diagnostic tests and evaluation tests online. Our approach is a reflexive one, based on the professional experience of the teachers that explore and incorporate new tools of Moodle with their students and coordinate the project MatActiva.

Porto: cidade amiga das pessoas idosas: um estudo centrado na visão de prestadores de serviços a pessoas idosas das freguesias de Cedofeita, Paranhos, St. Ildefonso, Bonfim e Campanhã

O envelhecimento da população é um fenómeno das sociedades contemporâneas simultâneo à crescente modificação do meio urbano. De modo a responder a estas alterações a Organização Mundial de Saúde (OMS) lançou o projeto Cidade Amiga das Pessoas Idosas que preconiza a adaptação das estruturas e serviços para que estes sejam acessíveis e promovam a inclusão dos cidadãos idosos. A presente investigação, de natureza qualitativa e exploratória, tem como objetivo verificar se a cidade do Porto possui características de uma cidade amiga das pessoas idosas através da visão de prestadores de serviços a pessoas idosas das freguesias de Paranhos, Cedofeita, St. Ildefonso, Bonfim e Campanhã. Pretende, assim, ser um contributo para o desenvolvimento do projeto Cidade Amiga das Pessoas Idosas na cidade portuense. Para tal, realizam-se 3 focus groups com prestadores de serviços selecionados a partir de uma amostragem por conveniência, onde se utiliza um guião de entrevista semi-estruturado com as seguintes categorias: espaços exteriores e edifícios, transportes, habitação, participação social, respeito e inclusão social, participação cívica e emprego, comunicação e informação e apoio comunitário e serviços de saúde. É possível verificar que os participantes partilham, de forma geral, uma imagem positiva da cidade do Porto, contudo, têm tendência a iniciar o discurso pelas características negativas da cidade. Colaboram também com sugestões de melhoria para a cidade. Pela perspetiva dos participantes é possível verificar que aspetos relacionados com espaços exteriores e edifícios, respeito e inclusão social e apoio comunitário e serviços de saúde se destacam pela negativa, enquanto aspetos intimos à participação social das pessoas idosas bem como, à comunicação e informação na cidade do Porto são na generalidade elogiados. Desta forma, indicam como positivo o aparecimento de novas iniciativas como as Universidades Seniores ou o projeto “Afetos” desenvolvido pela Misericórdia; as ofertas dirigidas à população sénior desenvolvidas pelas Juntas de Freguesia e a presença de jornais de distribuição gratuita, em espaços públicos. Por oposição, identificam como pouco amigo das pessoas idosas os passeios pouco largos, com obstáculos e pouco cuidados; a falta de casas de banho públicas; o desinvestimento em atividades intergeracionais e a carência de lares públicos na cidade.

The immediate effects of atlanto-occipital joint manipulation and suboccipital muscle inhibition technique on active mouth opening and pressure pain sensitivity over latent myofascial trigger points in the masticatory muscles

DESIGN: A randomized controlled trial.OB JECTIVE: To investigate the immediate effects on pressure pain thresholds over latent trigger points (TrPs) in the masseter and temporalis muscles and active mouth opening following atlanto-occipital joint thrust manipulation or a soft tissue manual intervention targeted to the suboccipital muscles. BACKGROUND : Previous studies have described hypoalgesic effects of neck manipulative interventions over TrPs in the cervical musculature. There is a lack of studies analyzing these mechanisms over TrPs of muscles innervated by the trigeminal nerve. METHODS: One hundred twenty-two volunteers, 31 men and 91 women, between the ages of 18 and 30 years, with latent TrPs in the masseter muscle, were randomly divided into 3 groups: a manipulative group who received an atlanto-occipital joint thrust, a soft tissue group who received an inhibition technique over the suboccipital muscles, and a control group who did not receive an intervention. Pressure pain thresholds over latent TrPs in the masseter and temporalis muscles, and active mouth opening were assessed pretreatment and 2 minutes posttreatment by a blinded assessor. Mixed-model analyses of variance (ANOVA) were used to examine the effects of interventions on each outcome, with group as the between-subjects variable and time as the within-subjects variable. The primary analysis was the group-by-time interaction. RESULTS: The 2-by-3 mixed-model ANOVA revealed a significant group-by-time interaction for changes in pressure pain thresholds over masseter (P<.01) and temporalis (P =.003) muscle latent TrPs and also for active mouth opening (P<.001) in favor of the manipulative and soft tissue groups. Between-group effect sizes were small. CONCLUSIONS: The application of an atlanto-occipital thrust manipulation or soft tissue technique targeted to the suboccipital muscles led to an immediate increase in pressure pain thresholds over latent TrPs in the masseter and temporalis muscles and an increase in maximum active mouth opening. Nevertheless, the effects of both interventions were small and future studies are required to elucidate the clinical relevance of these changes. LEVEL OF EVIDENCE : Therapy, level 1b. J Orthop Sports Phys Ther 2010;40(5):310-317. doi:10.2519/jospt.2010.3257. KEYWORDSDS: cervical manipulation, muscle trigger points, neck, TMJ, upper cervical.

Relação entre a unidade de biofeedback de pressão, deslocamento do centro de pressão e atividade eletromiográfica durante o active straight leg raising em indivíduos com e sem dor lombo-pélvica.

Introdução: A unidade de biofeedback de pressão, em indivíduos com dor lombo-pélvica, é utilizada durante exercícios de estabilização segmentar, no entanto ainda carece de evidência científica. Objetivo: Determinar a relação entre a unidade de biofeedback de pressão (UBFP), o deslocamento do centro de pressão no sentido médio-lateral (COPml) e a atividade eletromiográfica abdominal durante o active straight leg raising (ASLR) em indivíduos com e sem dor lombo-pélvica, bem como identificar diferenças entre os grupos. Metodologia: Estudo transversal analítico em 18 estudantes universitários voluntários com dor lombo-pélvica crónica inespecífica (GCD) e em 20 sem dor (GSD). Durante o ASLR (desafio postural dinâmico) foram avaliadas as variações máxima e média da pressão (recorrendo à UBFP) e do deslocamento do COPml (através da plataforma de forças), bem como a atividade muscular abdominal, bilateralmente, com recurso à eletromiografia de superfície. Estatisticamente recorreu-se à correlação de Spearman e ao teste Mann-Whitney U, ambos com um nível de significância de 0,05. Resultados: No GCD, ao contrário do GSD, não foi verificada uma relação entre a UBFP e a atividade do transverso abdominal/obliquo interno (TrA/OI) contra-lateral. Correlações moderadas, mas com sentidos opostos, foram evidenciadas em ambos os grupos, entre o deslocamento do COPml e a atividade do TrA/OI contra-lateral. Em ambos os grupos, a UBFP demonstrou estar fortemente correlacionada com o COPml. Não foram observadas diferenças significativas entre os grupos nas variáveis avaliadas. Conclusão: A UBFP, no GCD, não se apresentou relacionada com a atividade do TrA/OI. Contudo, demonstrou uma relação com o deslocamento do COPml, em ambos os grupos, sendo portanto um indicador de estabilidade do tronco e assim, uma ferramenta útil em ambiente clínico. No GCD observou-se que uma maior atividade muscular TrA/OI pressupõe maior deslocamento do COPml, sendo uma relação contrária à verificada no GSD, podendo ser um indicador da perda da sua ação tónica.

A B-learning strategy for Therapeutics at the Bachelor Level

Background Information:The incorporation of distance learning activities by institutions of higher education is considered an important contribution to create new opportunities for teaching at both, initial and continuing training. In Medicine and Nursing, several papers illustrate the adaptation of technological components and teaching methods are prolific, however, when we look at the Pharmaceutical Education area, the examples are scarce. In that sense this project demonstrates the implementation and assessment of a B-Learning Strategy for Therapeutics using a “case based learning” approach. Setting: Academic Pharmacy Methods:This is an exploratory study involving 2nd year students of the Pharmacy Degree at the School of Allied Health Sciences of Oporto. The study population consists of 61 students, divided in groups of 3-4 elements. The b-learning model was implemented during a time period of 8 weeks. Results:A B-learning environment and digital learning objects were successfully created and implemented. Collaboration and assessment techniques were carefully developed to ensure the active participation and fair assessment of all students. Moodle records show a consistent activity of students during the assignments. E-portfolios were also developed using Wikispaces, which promoted reflective writing and clinical reasoning. Conclusions:Our exploratory study suggests that the “case based learning” method can be successfully combined with the technological components to create and maintain a feasible online learning environment for the teaching of therapeutics.

Monitoring of ochratoxin a exposure of the Portuguese population through a nationwide urine survey — winter 2007

Ochratoxin A (OTA) is a mycotoxin produced by a variety of fungi, such as Penicillium verrucosum and Aspergillium spp., which has been found to have a wide number of potentially deadly toxic effects, and can enter the human organism through a variety of means. It then finds its way into the bloodstream and, after a lengthy process, is eventually excreted through the urine. It can thus be detected in its original form not only in blood samples but also in this biological medium. As such, and in an attempt to evaluate the exposure of the Portuguese population to this mycotoxin, morning urine samples were collected during the Winter of 2007, from each of five geographically distinct Portuguese locations — Bragança, Porto, Coimbra, Alentejo, and Algarve — and subjected to extraction by immunoaffinity columns and to OTA quantification through liquid chromatography coupled with fluorescence detection. Prevalent incidence was higher than 95% with Coimbra being the exception (incidence of 73.3%). In nearly all locations, the OTA content of most samples was found to be above the limit of quantification (LOQ) of 0.008 ng/ml. Indeed, excluding Coimbra, with an OTA content level of 0.014 ng/ml, all regions featured content values over 0.021 ng/ml.

Short- and medium-term effects of manual therapy on cervical active range of motion and pressure pain sensitivity in latent myofascial pain of the upper trapezius muscle: a randomized controlled trial

Objective: The purpose of this study was to investigate effects of different manual techniques on cervical ranges of 17 motion and pressure pain sensitivity in subjects with latent trigger point of the upper trapezius muscle. 18 Methods: One hundred seventeen volunteers, with a unilateral latent trigger point on upper trapezius due to computer 19 work, were randomly divided into 5 groups: ischemic compression (IC) group (n = 24); passive stretching group (n = 20 23); muscle energy technique group (n = 23); and 2 control groups, wait-and-see group (n = 25) and placebo group 21 (n = 22). Cervical spine range of movement was measured using a cervical range of motion instrument as well as 22 pressure pain sensitivity by means of an algometer and a visual analog scale. Outcomes were assessed pretreatment, 23 immediately, and 24 hours after the intervention and 1 week later by a blind researcher. A 4 × 5 mixed repeated- 24 measures analysis of variance was used to examine the effects of the intervention and Cohen d coefficient was used. 25 Results: A group-by-time interaction was detected in all variables (P b .01), except contralateral rotation. The 26 immediate effect sizes of the contralateral flexion, ipsilateral rotation, and pressure pain threshold were large for 3 27 experimental groups. Nevertheless, after 24 hours and 1 week, only IC group maintained the effect size. 28 Conclusions: Manual techniques on upper trapezius with latent trigger point seemed to improve the cervical range of 29 motion and the pressure pain sensitivity. These effects persist after 1 week in the IC group. (J Manipulative Physiol 301 Ther 2013;xx:1-10)

Distributed active traction control system applied to the RoboCup middle size league

This work addresses the problem of traction control in mobile wheeled robots in the particular case of the RoboCup Middle Size League (MSL). The slip control problem is formulated using simple friction models for ISePorto Team robots with a differential wheel configuration. Traction was also characterized experimentally in the MSL scenario for relevant game events. This work proposes a hierarchical traction control architecture which relies in local slip detection and control at each wheel, with relevant information being relayed to a higher level responsible for global robot motion control. A dedicated one axis control embedded hardware subsystem allowing complex local control, high frequency current sensing and odometric information procession was developed. This local axis control board is integrated in a distributed system using CAN bus communications. The slipping observer was implemented in the axis control hardware nodes integrated in the ISePorto robots and was used to control and detect loss of for traction. %and to detect the ball in the kicking device. An external vision system was used to perform a qualitative analysis of the slip detection and observer performance results are presented.

Networked embedded systems for active flow control in aircraft

Aerodynamic drag is known to be one of the factors contributing more to increased aircraft fuel consumption. The primary source of skin friction drag during flight is the boundary layer separation. This is the layer of air moving smoothly in the immediate vicinity of the aircraft. In this paper we discuss a cyber-physical system approach able of performing an efficient suppression of the turbulent flow by using a dense sensing deployment to detect the low pressure region and a similarly dense deployment of actuators to manage the turbulent flow. With this concept, only the actuators in the vicinity of a separation layer are activated, minimizing power consumption and also the induced drag.

Influência de diferentes estratégias de estabilização lombopélvica e de programas de exercícios de controlo motor no Active Straight Leg Raise

Introdução: O Active Straight Leg Raise (ASLR) tem sido sugerido como um indicador clínico da estabilidade lombopélvica. Estratégias passivas e ativas podem contribuir para aumentar esta estabilidade, assim como programas de exercício baseados nas mesmas estratégias ativas. Objetivos: Comparar os efeitos imediatos da compressão pélvica manual (CP), do drawing-in (DI) e do bracing abdominal (BA) durante o ASLR em indivíduos com e sem dor lombopélvica crónica e inespecífica, e avaliar o efeito prolongado das manobras de estabilização ativas através dos programas de exercícios de controlo motor, Pilates e McGill. Métodos: Estudo transversal, com uma amostra de 111 voluntários, 52 sem dor lombopélvica (NLPPG) e 59 com dor lombopélvica (LPPG), e estudo experimental, formado pelo LPPG dividido em 19 no grupo controlo (GC), 20 no grupo pilates (GP) e 20 no grupo mcgill (GMg). Foi avaliado o ASLR padrão, o ASLR com CP, o ASLR com DI e ASLR com BA. Os participantes foram avaliados antes e após as 8 semanas de implementação dos programas exercícios de McGill e Richardson, apenas aos respetivos grupos. Resultados: O LPPG apresentou significativamente maior score no ASLR comparativamente ao NLPPG (z=-9,361; p<0,001). Apesar do BA ter apresentado scores inferiores às restantes estratégias (p<0,001), todas elas foram capazes de diminuir o score do ASLR (p<0,001). Após a aplicação dos programas de exercícios, verificou-se que o GP (p<0,001) e o GMg (p<0,001) apresentaram scores significativamente menores no ASLR, relativamente ao GC. No GP e no GMg verificou-se uma diminuição do score do ASLR (Z=-4,028; p<0,001; Z=-4,179; p<0,001, respetivamente). Além disso, GMg apresentou uma tendência para apresentar menores scores do ASLR comparativamente ao GP. Conclusão: Qualquer uma destas manobras de estabilização quando adicionada ao ASLR pode aumentar a estabilidade lombopélvica, especialmente o BA. Os exercícios de Pilates e de McGill permitiram melhorar os scores do ASLR.

Towards Active Course Marks for Autonomous Sailing Competitions

This paper describes the environmental monitoring / regatta beacon buoy under development at the Laboratory of Autonomous Systems (LSA) of the Polytechnic Institute of Porto. On the one hand, environmentalmonitoring of open water bodies in real or deferred time is essential to assess and make sensible decisions and, on the other hand, the broadcast in real time of position, water and wind related parameters allows autonomous boats to optimise their regatta performance. This proposal, rather than restraining the boats autonomy, fosters the development of intelligent behaviour by allowing the boats to focus on regatta strategy and tactics. The Nautical and Telemetric Application (NAUTA) buoy is a dual mode reconfigurable system that includes communications, control, data logging, sensing, storage and power subsystems. In environmental monitoring mode, the buoy gathers and stores data from several underwater and above water sensors and, in regatta mode, the buoy becomes an active course mark for the autonomous sailing boats in the vicinity. During a race, the buoy broadcasts its position, together with the wind and the water current local conditions, allowing autonomous boats to navigate towards and round the mark successfully. This project started with the specification of the requirements of the dual mode operation, followed by the design and building of the buoy structure. The research is currently focussed on the development of the modular, reconfigurable, open source-based control system. The NAUTA buoy is innovative, extensible and optimises the on board platform resources.

The role of functional polymorphisms in immune response genes as biomarkers of BCG Immunotherapy outcome in bladder cancer: Establishment of a predictive profile in a Southern Europe population

OBJECTIVE: To evaluate the predictive value of genetic polymorphisms in the context of BCG immunotherapy outcome and create a predictive profile that may allow discriminating the risk of recurrence. MATERIAL AND METHODS: In a dataset of 204 patients treated with BCG, we evaluate 42 genetic polymorphisms in 38 genes involved in the BCG mechanism of action, using Sequenom MassARRAY technology. Stepwise multivariate Cox Regression was used for data mining. RESULTS: In agreement with previous studies we observed that gender, age, tumor multiplicity and treatment scheme were associated with BCG failure. Using stepwise multivariate Cox Regression analysis we propose the first predictive profile of BCG immunotherapy outcome and a risk score based on polymorphisms in immune system molecules (SNPs in TNFA-1031T/C (rs1799964), IL2RA rs2104286 T/C, IL17A-197G/A (rs2275913), IL17RA-809A/G (rs4819554), IL18R1 rs3771171 T/C, ICAM1 K469E (rs5498), FASL-844T/C (rs763110) and TRAILR1-397T/G (rs79037040) in association with clinicopathological variables. This risk score allows the categorization of patients into risk groups: patients within the Low Risk group have a 90% chance of successful treatment, whereas patients in the High Risk group present 75% chance of recurrence after BCG treatment. CONCLUSION: We have established the first predictive score of BCG immunotherapy outcome combining clinicopathological characteristics and a panel of genetic polymorphisms. Further studies using an independent cohort are warranted. Moreover, the inclusion of other biomarkers may help to improve the proposed model.

Osteoporotic hip fractures: Bisphosphonates sales and observed turning point in trend. A population-based retrospective study

The aim is to examine the temporal trends of hip fracture incidence in Portugal by sex and age groups, and explore the relation with anti-osteoporotic medication. From the National Hospital Discharge Database, we selected from 1st January 2000 to 31st December 2008, 77,083 hospital admissions (77.4% women) caused by osteoporotic hip fractures (low energy, patients over 49 years-age), with diagnosis codes 820.x of ICD 9-CM. The 2001 Portuguese population was used as standard to calculate direct age-standardized incidence rates (ASIR) (100,000 inhabitants). Generalized additive and linear models were used to evaluate and quantify temporal trends of age specific rates (AR), by sex. We identified 2003 as a turning point in the trend of ASIR of hip fractures in women. After 2003, the ASIR in women decreased on average by 10.3 cases/100,000 inhabitants, 95% CI (− 15.7 to − 4.8), per 100,000 anti-osteoporotic medication packages sold. For women aged 65–69 and 75–79 we identified the same turning point. However, for women aged over 80, the year 2004 marked a change in the trend, from an increase to a decrease. Among the population aged 70–74 a linear decrease of incidence rate (95% CI) was observed in both sexes, higher for women: − 28.0% (− 36.2 to − 19.5) change vs − 18.8%, (− 32.6 to − 2.3). The abrupt turning point in the trend of ASIR of hip fractures in women is compatible with an intervention, such as a medication. The trends were different according to gender and age group, but compatible with the pattern of bisphosphonates sales.
