- The Impact of Multicomponent Exercise Protocols Order on the Maximum Voluntary Contraction of Older WomenPublication . Monteiro, António; Rodrigues, Sandra; Matos, Sérgio; Encarnação, Samuel; Teixeira, José; Barbosa, Tiago M.; Rodrigues, Filipe; Forte, PedroThe aim of this study was to evaluate the impact of exercise order in multicomponent training (MCT) on the maximum voluntary contraction (MVC) of older women. A total of 91 older women, ranging in age from 60 to 85 years, were randomly assigned to either Group A or Group B. Group A performed a warm up followed by aerobic training and resistance training, whereas Group B followed a warm up followed by resistance training and aerobic training. A control group (CG) did not engage in any exercise interventions. Statistical analysis was conducted using one-way ANOVA for between-group comparisons, and ANOVA was used for repeated measures. The results revealed that Group A demonstrated significant increases in MVC for knee extensors (KEs) between M1 and M3 (p < 0.001) and between M2 and M3 (p < 0.001). Similarly, Group A exhibited significant increases in MVC for knee flexors (KFs) between M1 and M3 (p = 0.001) and between M2 and M3 (p < 0.001). Both Group A and Group B demonstrated significant increases in MVC for elbow flexors (EFs) between M1 and M3 (p < 0.001). Furthermore, Group B showed a significant increase in hand grip strength (HGS) between M1 and M3 (p < 0.001). Overall, the findings suggest that initiating MCT with aerobic training followed by resistance training is the most effective approach for improving muscle strength in older women.
- INDUSTRY 4 . 0 : LEGACY DEVICES INTEGRATION WITH OPC UA AND THE DIGITAL TWINPublication . Cavalcanti, Marcella Barros de Brito; Castro, Hugo Filipe Costelha de; Neves, Carlos Fernando Couceiro de SousaOver the years, the constant evolution of the industry has led to many advancements in factories and manufacturing systems. The terms "Smart Factories" and "Smart Manufacturing Systems" have been used to describe the latest wave of technological innovations that have transformed how factories operate. One of these innovations is the concept of the Digital Twin, which is a realistic virtual copy of a physical object. This technology allows entire manufacturing shop-floors to be digitalized, and physical processes to be tightly intertwined with their cyber counterparts. The development of Digital Twins encompasses several challenges, including model accuracy, security, and the integration of different devices and systems, including interoperability and standardization across them. The goal of this work is to develop key applications to support the implementation of Digital Twins in a Smart Factory environment, by describing an example of the development of an Industry 4.0 enabling application for a legacy device, as well as the design of a Digital Twin for a real industrial system from the ground up. A key result of this work is a successful use case of creating a Digital Twin for a quality control cell in the industry, using RobotStudio as the simulation environment and OPC UA as the communication protocol between the devices in the cell. The developed Digital Twin is capable of simulating the behaviour of the devices in the cell, as well as performing the cell’s control logic. It is also capable of storing historical process data, which could be analyzed and used to perform process optimization. Another relevant result is related to the use of a device’s Digital Twin to support the development of an application, performing tests and validation, while eliminating the need of accessing the real device. It shows that this technology can be used to speed up development and reduce downtime of industrial devices, thus reducing costs and improving the production process.
- CONTRIBUTOS PARA AS POLÍTICAS LOCAIS DE JUVENTUDE DO PORTO SANTO, A PARTIR DAS PREOCUPAÇÕES E PERCEÇÕES DOS/AS JOVENS E DAS PESSOAS E ENTIDADES QUE TRABALHAM COM JOVENSPublication . Lopes, Ana Sofia e Martins; Barreto, Maria Antónia Belchior FerreiraEste estudo pretendeu ouvir os/as jovens residentes ou que estudaram no Porto Santo, e as entidades que trabalham com os/as mesmos/as, de modo a reunir ideias, propostas e soluções sobre o que é importante para os/as jovens na ilha, dando, assim, um contributo para as políticas locais de juventude. Indo ao encontro da recomendação CM/Rec(2017)4 do Comité de Ministros do Conselho da Europa, pretendeu-se refletir sobre a importância da juventude e a necessidade das políticas públicas assumirem um papel pró-ativo que valorize a inclusão e o empenho dos/as cidadãos/ãs jovens na sociedade. A pergunta de partida que se colocou neste estudo foi: “Que oportunidades, desafios e soluções são identificados pelos/as jovens do Porto Santo – residentes, ou que não sendo residentes, estudaram na ilha –, com idades compreendidas entre os 15 e os 29 anos, e pelas pessoas que trabalham na área da juventude, no que diz respeito ao desenvolvimento do Porto Santo no domínio da juventude e das políticas de juventude?”. Nesse sentido, definiram-se três Objetivos Específicos: identificar as oportunidades e os desafios ao nível da educação, formação, empregabilidade, saúde, participação e tempos livres (1), propor ideias de projetos e atividades para dinamizar a área da juventude no Porto Santo (2) e priorizar as áreas de intervenção, ao nível das políticas públicas locais, relativas à área da juventude (3). Para tal, foram inquiridos/as 175 jovens entre os 15 e os 29 anos, realizados dois grupos focais e quatro entrevistas com informadores-chave, recorrendo-se, assim, a uma diversidade de estratégias dentro dos paradigmas quantitativo e qualitativo. Como resultado deste estudo, encontram-se diversas ideias, projetos e soluções, pensadas e priorizadas por jovens, para um maior desenvolvimento desta ilha, Porto Santo, situada no Arquipélago da Madeira.
