Sleep Quality among Medical Students of a Portuguese University
Publication . Ferreira, Rita; Brás, João; Fialho, Joana; Peixoto, Cristina
Introdução: O sono é um processo fisiológico complexo presente na maioria dos seres vivos. As perturbações do sono têm vindo a aumentar exponencialmente. Os estudantes universitários, particularmente, os estudantes de medicina, são especialmente vulneráveis a esta problemática. Contudo, a literatura existente relativa ao tema é escassa, especialmente, em Portugal. O objetivo deste estudo consiste em avaliar a qualidade de sono nos estudantes do curso Medicina da Universidade da Beira Interior, Covilhã, Portugal e analisar as diferenças e relações existentes de acordo com a idade, sexo, coabitação e ano de curso.
Métodos: Trata-se de um estudo transversal em que os estudantes envolvidos preencheram o Índice da Qualidade de Sono de Pittsburg (PSQI), previamente validado para a população portuguesa. Os valores obtidos, para cada componente do PSQI, foram inicialmente analisados para a população global, e posteriormente relacionados com as variáveis sociodemográficas, visando a obtenção de relações estatisticamente significativas.
Resultados: Duzentos noventa seis estudantes responderam ao questionário. Destes, 62,2% consideraram o seu sono bom; 42,4% obtiveram 1 na componente latência do sono; 50% admitiu dormir entre 6 a 7 horas; 73,9% evidenciou uma eficiência de sono adequada; 85,5% relatou pouco ou nenhum distúrbio do sono; 83,8% referiu nunca ter usado medicação para dormir; e 60,8% mencionou pouca ou nenhuma disfunção diurna. Relativamente ao PSQI global, 73,1% dos estudantes obtiveram uma pontuação superior a 5, indicando uma má qualidade de sono. Das raparigas, 74,7% e dos rapazes, 67,7% revelaram uma pobre qualidade de sono. Dos estudantes, que vivem sozinhos, 91,3% também exibiram uma pobre qualidade de sono. Relativamente ao ano letivo do curso no qual o inquérito foi aplicado, 82,4% dos estudantes do 1º ano reportaram uma pobre qualidade de sono, assim como 77,5% do 2º ano, 72,1% do 3º, 77,8% do 4º, 65,8% do 5º e 71,4% do 6º ano do curso.
Conclusão: Globalmente, os estudantes que participaram neste estudo apresentaram má qualidade de sono, com uma classificação no PSQI superior 5. Contudo, as classificações em cada um dos componentes não são tão negativas. A maioria dos participantes classificam o seu sono como bom ou muito bom, quase metade dos participantes referiram
dormir mais de 7 horas e a maioria apresentou uma eficiência de sono superior a 85%. De igual forma, 83,8% nunca usaram medicação para dormir. Não sendo um resultado robusto, torna-se imperioso a realização de mais estudos que o comprovem inequivocamente. Mais, tais estudos também serão imprescindíveis para identificar situações em que a
intervenção terapêutica melhorará tais parâmetros.
From Invasion to Valorization: Adsorbent Applications of Acacia dealbata Biomass in Portugal

Acacia dealbata, an invasive species in Portugal, produces large amounts of residual biomass during control operations, thereby presenting challenges and opportunities for sustainable valorization. Heavy metal contamination, including zinc (Zn), remains a critical environmental challenge due to its widespread industrial release and potential ecotoxicological impacts. This study explores the potential use of A. dealbata biomass as a biosorbent for zinc removal from aqueous solutions, comparing the performance of natural biomass and A. dealbata charcoal fines. Adsorption isotherms, kinetics, and surface characterizations were conducted to evaluate their physicochemical properties and sorption efficiency. The A. dealbata charcoal fines exhibited a significantly higher specific surface area (33 m2 g −1 ) and total pore volume (0.030 cm3 g −1 ) compared with the untreated biomass (1.4 m2 g −1 and 0.004 cm3 g −1 , respectively). Despite these structural differences, both materials demonstrated similar maximum adsorption capacities (23.36 and 23.79 mg g−1 for natural and charcoal fines, respectively). These results indicate that untreated A. dealbata biomass can perform as a biosorbent comparably to its carbonized form, representing a simple, low-cost, and sustainable alternative for heavy metal removal, offering a low-energy and sustainable alternative for Zn remediation.
SSENPV's Integrated Management Platform
Publication . Pinto, Bruno; Matos, Cristina Peixoto; Abrantes, Steven; Lourenço, Carolina; Fialho, Joana; Cravo, Ivone; Antunes, Maria José; Nascimento, Márcio
At the Polytechnic of Viseu (PV) [1], the number of students has been increasing [2], and it is hoped that this trend continues, for the sake of the literacy of the population that serves in its area of coverage and for the reduction of the desertification of the interior region in which is inserted. In the case of Students with Specific Educational Needs (SSEN) who attend the PV (SSENPV), it is extremely important to develop procedures that minimize the anxiety brought about by change for these students, as well as to facilitate their adaptation, to make the period of permanence in Higher Education (HE) an inclusive period, generating well-being, promoting academic success, and facilitating the transition to active life. To combat this phenomenon and since the PV is a Higher Education Institution (HEI) that is guided by equity in its community, in particular the student community, the SSENPV census is a crucial measure insofar as it is necessary to implement procedures, which must respect and obey individual specificities. It is also
intended that, regarding access to information on the platform, it will allow reducing asymmetries between students as well as access to services. To respond to this reality, within the scope of the Inova & Includes project. IPV I2 [3], a group of researchers, in partnership with the degree course in Computer Engineering at the Superior School of Technology and Management of Viseu (ESTGV) – curricular unit of “Project”, developed an integrated management platform for SSENPV. This platform, which is intended to be a contribution
to true equity in education in the PV, is based on the support of social impact in different dimensions, which translates into the implementation of the following profiles:
• Informative Profile: dissemination of legislation and other relevant information on Specific Educational Needs (SEN), ensuring centralized and accessible information management and streamlining procedures and support measures. • Academic Profile: registration and updating of data on the SSENPV. • Technical Evaluation and Follow-up Profile: registration of the SSENPV procedural evaluation, with automatic sending of technical evaluations to authorized users
How Destination Narratives Influence Visit Intention
Publication . Augusto, Luísa; Santos, Sara; Ferreira, Sónia; Santo, Pedro Espírito
The competitive environment of the tourism sector requires new strategies for constructing engaging narratives to stimulate interest, raise awareness and create an emotional connection with visitors, allowing for greater involvement that can influence their visit to the destination. The conceptual model of this study aims to analyse how destination
narratives promote the intention to visit, exploring the influence of narrative structure and immersion on tourists' positive emotions, attitudes and behaviours. This study uses a quantitative approach based on structural equation modelling structural equations using the AMOS software. Considering a sample of 901 respondents, this research allowed us to
conclude that the narratives influenced positive emotions and attitudes towards regions, conditioning the intention to visit the destination. In this way, this study brings contributions to academia and the professional world, as it allows for a deeper understanding of effective tourism marketing strategies and their practical implications.
Uma História de Sucesso: O Caso da Produção Audiovisual do Jornal do Centro
Publication . Costa Lopes, Mónica Dulce; Ferreira, Sónia
The global epidemiological outbreak caused by Sars-CoV-2, which resulted in the COVID-19 pandemic, has significantly affected different sectors of society. The impact on audiovisual production was no exception. The restrictive measures imposed to prevent the spread of the virus have had notable effects on film production, television programs and
other audiovisual content. Many production jobs were cancelled or postponed. To overcome these scenarios, adaptation had to be rapid and various strategies had
to be adopted. At the same time, the pandemic has also led to new public behaviours and preferences, such as increased demand for streaming platforms.
This article focuses on the study of this impact in the specific case of the audiovisual production of Jornal do Centro during the pandemic period. Jornal do Centro
produces informative, entertaining, institutional, and promotional audiovisual content. Through the application of the interview survey, this research aims to explain how the production process, in each of the pre-production, production and postproduction phases, overcame limitations, adapted, and created solutions. It also reveals which strategies are
maintained in the current scenario.
