- A SISTÉMICA FAMILIAR NO CUIDADO DE ENFERMAGEM CENTRADO NA FAMÍLIA IMPACTO DE UM PROGRAMA DE FORMAÇÃOPublication . Henriques, Carolina; Jordão, Tânia Fernanda Mesquita da SilvaA enfermagem de saúde familiar é uma disciplina recente, com evolução nas últimas décadas. Os estudos nesta área indiciam que a abordagem sistémica da família não é prática habitual pelos profissionais. Pretende-se com este estudo conhecer a perceção dos conceitos de família e de enfermagem de saúde familiar, avaliar os conhecimentos sobre sistémica familiar e avaliar o impacto de um programa de formação centrado nos conhecimentos sobre sistémica familiar no cuidado à família em oito enfermeiros que integram uma Unidade de Saúde Familiar de Portugal. Utilizou-se a aplicação de questionário autoadministrado sobre o mesmo grupo de sujeitos, em dois momentos: Uma avaliação inicial e uma avaliação após o programa de formação. Verificou-se o aumento dos conhecimentos nos enfermeiros sujeitos ao programa de formação, validando a hipótese de investigação: Existem diferenças estatisticamente significativas nos conhecimentos sobre sistémica familiar no cuidado à família, dos enfermeiros que integram uma Unidade de Saúde Familiar, antes e após a implementação de um Programa de Formação, destacando a necessidade e importância de desenvolver e implementar programas de formação neste âmbito para profissionais de enfermagem.
- Dietitians and Nutritionists Behaviour on Social Media: A Scoping Literature ReviewPublication . Saboia, Inga; Almeida, Ana Margarida Pisco; Sousa, Pedro; Pernencar, C.At its present state, Social Media (SM) is an important stage to promote user participation, acting as an open space for the discussion of a multitude of fields, one of which being health. Professionals, like Registered Nutritionists and Dietitians (RNDs), whose access to media was traditionally more restricted, are also more engaged in this new context, creating a new scenario. To better understand how is this group of professionals using social media to communicate with their audiences is the main objective of this study. To approach this topic, a mapping was conducted, followed by a presentation of the summary of the evidence discovered: RDNs demographic and professional profile; their most used social media tools; the reasons why they use social media; their common behaviours and attitudes, as well as a review of the gaps and shortcomings in the literature. A literature review, using a structured approach was also conducted. 2877 works were screened, but only 8 were associated with answers. Of these 8, there were 2 studies that partially presented a quantitative analysis. Results show lacks in consolidated studies that can be used to support the creation of knowledge in this field. This lead to conclude that research about social media usage by nutritionist, at present, remains in a nascent stage and requires further studies.
- Sustainability Report Evolution: The Nestlé Case Study ApplicabilityPublication . Eugénio, Teresa; Rodrigues, Susana; Gonçalves, Marco JoséThis chapter is a unique case study that aims to present the evolution of non-financial reporting in Nestlé Portugal from 2007 to 2016 with the aim to study in-depth the Nestlé sustainability report practices. This study proposes to identify the key milestones in the evolution of this type of report, to compare with the disclosure strategy of Nestlé international, to understand if this company follow the IIRC guidelines, to identify the contribution of the audit by an independent entity, to conclude if Nestlé contributes to the achieving of United Nations Sustainable Development Goals, and to identify if the awards Nestlé received matter in its sustainability initiatives. Public institutional information was preferably used, particularly the sustainability report and integrated report, processed with various work tools using the technique of content analysis. The conclusions made it possible to understand that Nestlé emerges as a company that integrates these issues into its strategy and can be a model for companies that wish to follow this report path towards sustainability.
- Instrumentos de educação alimentar e nutricional para crianças em idade pré-escolar: necessidades e desafios atuaisPublication . Pontes, Sofia; Custódio, Susana; Graça, PedroIntroduction: In Portugal there have been nutrition education programs aimed at children, using different instruments and methodologies. It is currently agreed that eating habits in early childhood have a strong impact on future health, being a window of opportunity for the modulation of eating habits for adult life. Nutrition education aimed at pre-school children is a very complex subject as it involves the child's development, pedagogy, and behavioral change. Objectives: To understand the development of pre-school children and describe the nutrition education instruments most used in this age as well as their possible impact on knowledge and food behaviour. Methodology: Narrative review of the literature using database search in Pubmed, ISI Web of Knowledge and the Online Knowledge Library. Results: Pre-school children need nutrition education tools that are appropriate to their cognitive abilities and that stimulate their interest. The most used nutrition education tools are food guides, children's stories, or games. Conclusions: Nutrition education instruments to be used at pre-school age should be tools for the realization of playful and meaningful moments of learning. Stories, traditional games, or digital games are thus valid instruments for this purpose and should be explored by educators to approach the topic of food.
- Comprehensive review on full bone regeneration through 3D printing approachesPublication . Fernandes, Cristiana; Moura, Carla; Ascenso, Rita M.T.; Amado, Sandra; Alves, Nuno; Pascoal-Faria, PaulaOver the last decades, the number of work accidents associated with bone fractures has increased leading to a growing concern worldwide. Currently, autografts, allografts, and xenografts are used for bone regeneration. However, their application has associated risks. Tissue engineering (TE) has brought solutions to address these problems, through the production of temporary supports, providing mechanical support to the formation of new bone tissue and biocompatible and biodegradable scaffolds, which allow cell adhesion and proliferation to ensure bone formation. The combination of materials and structure with the technique to be used will directly influence their physical and chemical properties and, consequently, their action in contributing to bone regeneration. Thus, the focus of this chapter is to perform an exhaustive literature review and a critical analysis of the state of the art in bone TE and present a proposal of an optimized temporary support geometry for bone regeneration in case of large bone defects. For this, it was listed and identified the best choice of biomaterials, fabrication method, cell type and their culture conditions (static vs. dynamic), and/or the inclusion of growth factors for the repair of large bone defects.
- Benchmarking bioinspired machine learning algorithms with CSE-CIC-IDS2018 network intrusions datasetPublication . Ferreira, Paulo; Antunes, MárioThis paper aims to evaluate CSE-CIC-IDS2018 network intrusions dataset and benchmark a set of supervised bioinspired machine learning algo rithms, namely CLONALG Artificial Immune System, Learning Vector Quantization (LVQ) and Back-Propagation Multi-Layer Perceptron (MLP). The results obtained were also compared with an ensemble strategy based on a majority voting algorithm. The results obtained show the appropri ateness of using the dataset to test behaviour based network intrusion de tection algorithms and the efficiency of MLP algorithm to detect zero-day attacks, when comparing with CLONALG and LVQ.
- Stability, kinetics, and application study of phycobiliprotein pigments extracted from red algae Gracilaria gracilisPublication . Pereira, Tatiana; Barroso, Sonia; Mendes, Susana; Gil, Maria M.Phycobiliprotein (PBP) pigments were extracted from red algae Gracilaria gracilis through maceration in phosphate buffer using previously optimized conditions. The stability of PBPs in the extracts was assessed by monitoring the extracts at different pHs and temperatures for 10 days. Since phycoerythrin (PE) is the main PBP present in G. gracilis, PE content was spectroscopically determined and used as a response factor. Kinetic modeling was used to describe PE degradation under different ranges of T and pH. The pigment extracts presented higher stability at pH 6.9 and −20 °C. PE was semipurified by precipitation with ammonium sulphate 65% followed by dialysis against water until a purity index of 0.7. The pigment was successfully applied as colorant in pancakes and yogurts with a pigment concentration of 0.15%. This study highlights the potential of PE pigments extracted from G. gracilis for applications in food products.

- Empregabilidade e ensino superior: o estudo de caso do mestrado em Gestão e Direção Hoteleira - ESTMPublication . Viana, Ana Sofia; Pais, Sónia; Sousa, Ana Elisa; Schön, MichaelEmpregabilidade é uma meta para todos aqueles que fazem um mestrado ou outro curso superior. No entanto, mais importante do que conseguir um bom emprego é encontrar o emprego para o qual os estudantes foram preparados durante os estudos e permitir-lhes alcançar a carreira que desejam/ambicionam. Neste sentido, o mestrado em Gestão e Direção Hoteleira da Escola Superior de Turismo e Tecnologia do Mar (ESTM) do Politécnico de Leiria foi projetado para permitir que os estudantes desenvolvessem competências organizacionais das muitas responsabilidades operacionais necessárias para gerir um hotel e que estão ligadas a conceitos práticos da tomada de decisões de gestão. Para preparar melhor os estudantes para o que o mercado de trabalho precisa e os empregadores desejam, é importante entender como o mercado de trabalho recebeu os estudantes após a graduação e se os empregadores reconheceram essas qualificações. Portanto, o objetivo deste estudo foi saber onde estão os mestres e o que estão a fazer no mercado de trabalho após o término deste mestrado, se sentem que a graduação foi importante e se lhes deu alguma vantagem no alcance de melhores posições de trabalho. Foi aplicado um método quantitativo a este estudo através da realização de um questionário a 19 mestres em Gestão e Direção Hoteleira. Os resultados mostraram que apesar do esforço das instituições de ensino superior procurarem, através dos mestrados, dar maiores competências aos futuros recursos humanos das organizações, a maioria das organizações ainda não reconhece nem valoriza muito estas formações.
