Metodologia. Para este estudo correlacionado definiram-se como objetivos: avaliar as características sociodemográficas, profissionais e clínicas da pessoa com uma ostomia; avaliar a sua qualidade de vida e relacioná-la com variáveis sociodemográficas e clínicas. Participaram 23 Pessoas com Ostomia que responderam a uma entrevista estruturado constituído por Dados Sociodemográficos, profissionais e clínicas e qualidade de Vida ( City of Hope Quality of live Questionnaire, de Grant et al, 2004).
Resultados: A maioria dos participantes são de sexo masculino (69,6%) com uma média de idade foi de 66,2±14,2 anos, sendo de realçar que o maior número 10 (43,5%) tem 1º ciclo do ensino básico como escolaridade e a maioria (52,2%) está reformada.
A maioria apresenta colostomia, tendo em 60,9% dos casos sido marcada previamente à intervenção e na maioria dos casos pelo médico (56%,5). O tempo médio em dias da ostomia foi de 1472 (4 anos) ±1248 dias. Verificou-se que o maior número de utentes recebeu apoio do (a) enfermeira (o) seguido da família.
Não se encontraram diferenças entre a qualidade de vida e as variáveis sociodemográficas e clínicas
Conclusão: Conhecer a qualidade de vida e os fatores que interferem com a mesma é fundamental para um bom planeamento de intervenções de enfermagem adequadas a cada utente.Framework: This observational and quantitative study addresses issues related to the quality of life of people with ostomies.
Methodology. The objectives of this correlational study were: to assess the sociodemographic, professional and clinical characteristics of people with ostomies; to assess their quality of life and relate it to sociodemographic and clinical variables. 23 people with ostomies took part and answered a structured interview consisting of sociodemographic, professional and clinical data and quality of life (City of Hope Quality of life Questionnaire, by Grant et al, 2004).
Results: The majority of the participants were male (69.6%) with an average age of 66.2±14.2 years, with the largest number (43.5%) having completed primary school and the majority (52.2%) being retired.
The majority had a colostomy, and in 60.9% of cases it had been scheduled prior to the intervention and in most cases by the doctor (56%,5). The average time of ostomy in days was 1472 (4 years) ±1248 days. The largest number of patients received support from their nurse, followed by their family.
No differences were found between quality of life and sociodemographic and clinical variables
Conclusion: Knowing the quality of life and the factors that interfere with it is fundamental for planning appropriate nursing interventions for each patient
3SqAir Project: A Living Lab Towards Sustainable Smart Strategy for Indoor Climate Quality Assurance in Classrooms
No full textArticle number - 584This article belongs to the Special Issue Modelling of Indoor Air Quality and Thermal ComfortThe indoor climate quality in classrooms at the University of Coimbra, Portugal, was investigated as part of the 3SqAir project, supported by the Interreg SUDOE program. This research focused on two equipped classrooms with different ventilation systems: natural and mechanical ventilation. Both classrooms were continuously monitored for IEQ parameters: thermal comfort, indoor air quality, noise, and lighting during heating and cooling seasons. Air temperature, relative humidity, CO2 concentration, particulate matter, nitrogen dioxide, volatile organic compounds, formaldehyde, sound pressure level, and illuminance were measured. Outdoor weather conditions were also recorded. The primary focus was on air temperature, CO2 concentrations, and relative humidity, while air change rates (ACH) were estimated using the Tracer Gas Method. The results showed inadequate thermal conditions in both classrooms, particularly during the heating season. Most weekly mean CO2 concentrations were within acceptable limits, while ACH were below standard recommendations in four CO2 decay phases. Simulations of CO2 decay revealed further air quality gaps in each room. Corrective measures within the 3SqAir project framework were suggested for approval and implementation while monitoring continues. This work represents the first phase in an evolving study towards developing sustainable strategies for improving indoor air quality in classrooms.This research was funded in whole or in part by the Fundação para a Ciência e a Tecnologia, I.P.

Uma análise comportamental dos preditores de adesão ao exercício e do seu impacto económico no contexto do fitness
No full textEste estudio pretendía examinar la relación entre las percepciones de los clientes sobre los comportamientos de los fisiólogos del ejercicio, los tipos de motivación y su influencia posterior en la adherencia al ejercicio durante un periodo de seis meses. Además, evaluamos el impacto financiero del abandono de los clientes en los ingresos de los gimnasios durante este periodo. Métodos: Una muestra de 1.803 individuos (edades 18-54; M = 26,61, SD = 5,48) inscritos en gimnasios de todo Portugal participaron en este estudio. Resultados: Durante el periodo de seis meses, el 42% de los clientes cancelaron sus abonos, lo que supuso una pérdida de ingresos mensual estimada de 28.659,60 euros al final del sexto mes. Acumulativamente, los gimnasios experimentaron una pérdida total de ingresos de 110.393,27 euros durante el periodo de estudio. Conclusiones: Los hallazgos sugieren que los comportamientos de apoyo a las necesidades por parte de los fisiólogos se asocian positivamente con la motivación autónoma, que a su vez promueve la adherencia al ejercicio a largo plazo. Por el contrario, los comportamientos que frustran las necesidades están relacionados con la motivación controlada, que afecta negativamente al mantenimiento del ejercicio. Estos datos ponen de relieve la importancia de las estrategias de motivación tanto para la retención de clientes como para la sostenibilidad financiera de los gimnasios.This study aimed to examine the relationship between clients' perceptions of exercise physiologists' behaviors, motivational types, and their subsequent influence on exercise adherence over a six-month. Additionally, we assessed the financial impact of client dropout on fitness center revenues during this timeframe. Methods: A sample of 1,803 individuals (ages 18-54; M = 26.61, SD = 5.48) enrolled in fitness centers across Portugal participated in this study. Results: Over the six-month period, 42% of clients canceled their memberships, resulting in an estimated monthly revenue loss of €28,659.60 by the end of the sixth month. Cumulatively, the fitness centers experienced a total revenue loss of €110,393.27 during the study period. Conclusions: The findings suggest that need-supportive behaviors from physiologists are positively associated with autonomous motivation, which in turn promotes long-term exercise adherence. In contrast, need-thwarting behaviors are linked to controlled motivation, which negatively impacts exercise maintenance. These insights highlight the importance of motivational strategies in both client retention and financial sustainability for fitness centers.Este estudo teve como objetivo examinar a relação entre os comportamentos dos fisiologistas do exercício percebidos pelos clientes, os tipos de motivação e a sua subsequente influência na adesão ao exercício durante um período de seis meses. Adicionalmente, avaliámos o impacto financeiro da desistência de clientes nas receitas do centro de fitness durante este período. Métodos: Participaram neste estudo 1.803 indivíduos (idades 18-54; M = 26,61, DP = 5,48) inscritos em ginásios em Portugal. Resultados: Durante o período de seis meses, 42% dos clientes cancelaram as suas subscrições, resultando numa perda de receitas mensais estimada em 28.659,60 € no final do sexto mês. Cumulativamente, os centros de fitness registaram uma perda total de receitas de 110.393,27 euros durante o período do estudo. Conclusões: Os resultados sugerem que os comportamentos de apoio às necessidades dos fisiologistas estão positivamente associados à motivação autónoma, que por sua vez promove a adesão ao exercício a longo prazo. Em contraste, os comportamentos que frustram as necessidades estão associados à motivação controlada, o que tem um impacto negativo na manutenção do exercício. Estas conclusões realçam a importância das estratégias motivacionais tanto na retenção de clientes como na sustentabilidade financeira dos centros de fitness.info:eu-repo/semantics/publishedVersio
FUNCTIONING AND POTENTIALITIES OF THE DIDACTIC COURSE AS A READING AND WRITING TEACHING DEVICE: THE GENRE INTERVIEW IN THE 3RD YEAR OF SCHOOLING
No full textNeste artigo pretendemos apresentar um dispositivo didático orientado para o ensino de géneros textuais: o percurso didático (AUTOR1, 2019; AUTOR1, GONÇALVES & COUTINHO, 2022). Concebido no programa de trabalhos do interacionismo sociodiscursivo (BRONCKART, 1997), este dispositivo inspira-se na sequência didática (DOLZ, NOVERRAZ & SCHNEUWLY, 2004) e na sequência de ensino (PEREIRA & CARDOSO, 2013; PEREIRA, CARDOSO & GRAÇA, 2013). Depois de explicitarmos os contornos conceptuais do percurso didático, apresentaremos os resultados de uma investigação desenvolvida em torno deste dispositivo de ensino, em Portugal, no 1.º Ciclo do Ensino Básico em Portugal (3.º ano de escolaridade), em 2022, com enfoque no género entrevista (impressa, destinada ao público infantojuvenil). Ao longo do artigo, daremos conta das três etapas que nortearam a investigação: i) descrição prévia do género a focar (com base na revisão de literatura e na análise das práticas sociais de referência); ii) relato da experiência didática realizada (com recurso à observação participante, em contexto de investigação sobre a própria prática – PONTE, 2002); iii) análise da entrevista produzida coletivamente pelos alunos, no momento final do percurso didático, tendo em conta três dimensões de análise: temático-estrutural, linguística, gráfica. Esperamos, assim, não apenas ilustrar o funcionamento do percurso didático, como também evidenciar as potencialidades deste dispositivo de ensino-aprendizagem, sobretudo a dois níveis: compreensão e produção de textos e de géneros textuais; atividade metalinguística.In this article we intend to present a didactic device directed to the teaching of textual genres: the didactic path (JORGE, 2019; JORGE; GONÇALVES; COUTINHO, 2022). Conceived in the work programme of socio-discursive interactionism (BRONCKART, 1997), this device is inspired by the didactic sequence (DOLZ; NOVERRAZ; SCHNEUWLY, 2004) and teaching sequence (PEREIRA; CARDOSO, 2013; PEREIRA; CARDOSO; GRAÇA, 2013). After explaining the conceptual outlines of the didactic path, we will present the results of an investigation developed around this teaching device, in Portugal, concerning a primary school class (3rd grade), in 2022, focusing on the interview genre (printed, aimed at the juvenile public). Throughout the article, we will take account of the three stages that led the investigation: i) a previous description of the genre to be focused on (based on literature review and social reference practices analysis); ii) report of the didactic experience which had been carried out (recurring to participant observation, in the context of research on the practice itself (PONTE, 2002)); iii) analysis of the interview produced collectively by the students, at the final moment of the didactic path, taking into account three analysis dimensions: thematic, structural, linguistic, graphic. The results will show that, even in early moments of formal learning, the didactic path can prove to be an effective device in what concerns the learning and the development of textual and genological skills (reading and writing), linguistic skills (effective use of language/grammar, in texts) and metalinguistic skills (reflection on the social and communicative use of the language).info:eu-repo/semantics/publishedVersio
Perceções e práticas sobre a atuação interdisciplinar numa Equipa Intra Hospitalar de Suporte em Cuidados Paliativos: um estudo qualitativo
No full textSystemic Approaches to Coopetition: Technology and Service Integration in Dynamic Ecosystems Among SMEs
No full textArticle number - 97In the globalized, technologically advanced landscape, coopetition—simultaneously cooperating and competing—has become a key strategy for innovation and enhanced value creation. This research focuses on the impact of technology-driven coopetition networks in the Portuguese ornamental stone sector, using a framework based on Service-Dominant Logic (S-D Logic). It emphasizes the importance of resource integration, service exchange, and institutional arrangements in successful coopetition. Employing a two-phase experimental approach with selected small and medium enterprises (SMEs), this study assesses customer perceptions of product quality under traditional best practices versus those enabled by technology-driven coopetition networks. The results indicate a notable improvement in the customer-perceived quality and outcome consistency. The statistical analysis shows that these networks allow firms to better align with customer expectations, optimize resource allocation, and improve operational coordination. The findings highlight the strategic potential of coopetition networks, particularly when augmented by advanced technologies like IoT-based systems. These networks facilitate sustainable value co-creation and operational resilience by enabling firms to share expertise, distribute tasks, and synchronize efforts. This research contributes to the coopetition and S-D Logic literature by offering a practical framework for firms aiming to boost competitiveness and sustain growth in dynamic service ecosystems
El efecto del juego en la promoción del equilibrio y la prevención del riesgo de caídas en los ancianos
No full textOs autores do artigo agradecem às instituições e aos utentes participantes, pela sua disponibilidade e
participação. Agradecemos também o apoio do Center for Innovative Care and Health Technology
(ciTechCare), do Instituto Politécnico de Leiria, pela cedência de equipamento e condições técnicas à
realização do estudo.Introdução: O jogo analógico dirigido a pessoas idosas com alterações de equilíbrio e risco de
queda demonstrou alguns potenciais resultados, contudo os estudos são escassos.
Objetivo: O presente estudo pretendeu testar o potencial de um jogo analógico na melhoria do
equilíbrio e diminuição do risco de quedas, bem como caracterizar o desempenho dos
participantes no jogo e a sua relação com as variáveis de equilíbrio e risco de queda.
Metodologia: Foram analisados dados recolhidos em três momentos: inicial (T0); após 6
semanas de intervenção com jogo (T1) e final (T2), após 6 semanas sem intervenção com jogo.
Foram calculadas correlações entre o desempenho no jogo nas diferentes grelhas (S, M e L) e
os indicadores de equilíbrio (Teste de Levantar e Ir (TUG) e teste Tinetti); estes testes foram
comparados entre os períodos com e sem o jogo.
Resultados: Dez pessoas idosas (87,60±7,25 anos; 8 mulheres) participaram no estudo,
melhorando significativamente os valores de TUG apenas entre T0-T1 (p=0,002). Os valores do
teste de Tinetti melhoraram significativamente nos dois períodos de intervenção (p=0,001;
p=0,006). O desempenho na grelha L demonstrou correlação com o teste Tinetti (T0 - ρ = -0,664;
p = 0,036) e com o TUG apenas na 2ª tentativa (T0; r = 0,680; p = 0,030*).
Conclusão: Existe potencial benefício do jogo analógico na melhoria do risco de queda (TUG) na
pessoa idosa institucionalizada. O jogo implementado, no seu nível mais exigente (grelha L),
parece adequar-se ao contexto de reabilitação, promovendo aprendizagem ao longo do tempo.Introduction: The analogic game demonstrated potential results in old people with decreased
balance and fall risk, however related studies are scarce.
Aim: The present study aimed to test the potential of an analogue game in improving balance
and reducing the risk of falls, as well as to characterize the performance of the participants in
the game and its relationship with the variables of balance and risk of falling.
Method: Data were collected at three moments: initial (T0); after 6 weeks of intervention with
game (T1) and final (T2), after 6 weeks without intervention with game. Correlations were calculated
between the performance in the game in the different grids (S, M and L) and the balance
indicators (Timed-up and Go Test (TUG) and Tinetti test); these tests were compared between
the different periods.
Results: Ten elderly people (87.60±7.25 years; 8 women) participated in the study, significantly
improving TUG values only between T0-T1 (p=0.002). Values from Tinetti test improved significantly
in the two intervention periods (p=0.001; p=0.006). The performance in the grid L
showed correlation with the Tinetti test (T0 - ρ = -0.664; p = 0.036) and with the TUG only in
the 2nd attempt (T0; r = 0.680; p = 0.030*).
Conclusion: There is a potential benefit of analogue play in improving the risk of falls (TUG) in
institutionalized elderly people. The implemented game, at its most demanding level (grid L),
seems to fit the rehabilitation context, promoting learning over time.Introducción: El juego analógico dirigido a personas idas con alteraciones de equilibrio y riesgo de quedar demostrados algunos resultados potentes, con todos los estudios en cassos.

Unlocking the Power of Ads: A Cross-Cultural Examination of Consumers’ Advertising Value Perceptions
No full textThe field of advertising has attracted significant interest from researchers. However, although previous studies suggest that attitudes and behavioral responses to advertising diverge across cultures, cross-cultural research to assess disparities in consumer behavior as a result of the perceived value of advertising is considered to be scarce. Building on the advertising value model and on the Stimulus-Organism-Response (SOR) framework, this study aims to explore cross-cultural similarities and differences in the consumers’ perceptions of the advertising value. We investigate the impact of informativeness, entertainment, credibility, and favorable predisposition toward advertising on the perceived value of an ad, and how this factor, in turn, influences brand image, word-of-mouth, and purchase intention across markets. Data were collected through an online survey addressed to two markets: Belarus and Portugal. A total of 293 valid answers were obtained, 155 from Belarus and 138 from Portugal. Data were analyzed using partial least squares structural equation modeling. Findings indicate that credibility and favorable predisposition toward advertising leverage the perceived value of an ad in both markets. However, results show that informativeness enhances the perceived value of an ad only in the Belarusian market, while entertainment has a significant positive influence only in the Portuguese market. Across both markets, the perceived value of advertising enhances brand image, which subsequently leverages word-of-mouth and purchase intention.This work was supported by National Funds of the FCT Portuguese Foundation for Science and Technology within the project UIDB/04928/2020
Chemical Characterization and Bio-Screening of Neuroprotective Potential of Brazilian Brown Seaweed Canistrocarpus cervicornis in 6-OHDA-Induced Neurotoxicity Model
No full textBrazilian native seaweed Canistrocarpus cervicornis (Ochrophyta, Dictyotaceae) is recognized for its chemodiversity, particularly cyclic diterpenes and polysaccharides, yet its relevance to neurological disorders remains unexplored. This study evaluated the neuroprotective potential of a hydroethanolic extract (ECCH), its polar fraction (CCFPol), a dichloromethane extract (ECCD), and eight derived fractions (CCF1–2, CCF3, CCF4, CCF5–6, CCF7, CCF8–10, and CCF11–15). Cytotoxicity was evaluated in SH-SY5Y neuroblastoma cells, and neuroprotection was examined against 6-OHDA–induced toxicity. The mitochondrial membrane potential, ROS and H2O2 generation assays were conducted to explore the mechanisms underlying the observed effects. Among the key findings, the CCF3 fraction exhibited a high content (75.04%) of dolastane-type diterpenoids. Both CCFPol (100 µg/mL) and CCF3 (1 µg/mL) increased cell viability to 68.43 ± 4.60% and 60.61 ± 0.80%, respectively, compared with 6-OHDA–treated cells (50.70 ± 2.71%). Additionally, CCF3 and CCFPol reduced H2O2 levels (200.0 ± 18.19% and 195.5 ± 16.13%, respectively, vs. 6-OHDA-treated cells: 302.2 ± 17.07%) and lowered intracellular ROS (122.6 ± 22.7% and 129.6 ± 19.4%, respectively, vs. 6-OHDA-treated cells: 153.0 ± 32.7%). This is the first study to demonstrate the neuroprotective potential of the C. cervicornis in a 6-OHDA-induced neurotoxicity cellular model, contributing to the understanding of marine bioactive resources and their relevance for neurological research. Additional studies aimed at isolating the active constituents and clarifying their mechanisms of action will further strengthen and expand the biological relevance of this specie as source of neuroprotective agents.We would like to thank the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) for PhD and sandwich doctorate scholarship (TCS), the INCT Nanotechnology for Sustainable Agriculture, the Coordination for the Improvement of Higher Education Personnel–Brazil (MEC-CAPES INCTNanoAgro #888887.986628/2024-00), and the São Paulo Research Foundation (FAPESP) for the technical fellowship TT IV-A [Process 2025/19.448-9] (J.M.C.O)
VULNFUSION: PLATAFORMA DE INTEGRAÇÃO DE FERRAMENTAS OPEN- SOURCE SAST
No full textCiclos de desenvolvimento acelerados e o uso de bibliotecas de terceiros aumentam a
probabilidade de existirem lacunas de segurança no código, agravada pela insuficiente
formação em segurança dos programadores. A análise de segurança manual é
lenta e cara, o que torna as ferramentas de análise de segurança estática, static
application security testing (SAST), essenciais para identificar vulnerabilidades de
forma eficiente.
Contudo, as ferramentas SAST geram muitos falsos positivos, exigindo verificação
manual. Este projeto propõe uma plataforma, intitulada VulnFusion, que integra
múltiplas ferramentas SAST para melhorar a robustez da análise de segurança,
e que utiliza técnicas de inteligência artificial (IA) para enriquecer os resultados
obtidos.
A plataforma VulnFusion visa reduzir os falsos positivos e aumentar a eficiência
na deteção de vulnerabilidades e auxiliar na prioritização dos esforços de mitigação,
adaptando-se às necessidades dos programadores e organizações.
O presente documento inclui uma breve revisão de ferramentas SAST open-source
existentes, o desenvolvimento da plataforma VulnFusion e dos processos de agregação
de resultados e enriquecimento dos mesmos, e apresenta os testes realizados e os
resultados obtidos.
Os resultados demonstraram uma melhoria na cobertura e precisão da deteção de
vulnerabilidades face à utilização de uma única ferramenta, com ganhos no F1-score
para categorias como command injection (47,8%) e SQL injection (36,5%) após a
integração de múltiplas ferramentas SAST e enriquecimento por IA.Accelerated development cycles and the use of third-party libraries increase the
likelihood of security gaps in the code, exacerbated by the insufficient security
training of developers. Manual security analysis are slow and expensive, making
static application security testing (SAST) tools essential for efficiently identifying
vulnerabilities.
However, SAST tools generate many false positives, requiring manual verification.
This project proposes a platform, titled VulnFusion, that integrates multiple SAST
tools to improve the robustness of security analysis and uses artificial intelligence
(AI) techniques to enrich the results produced.
The platform VulnFusion aims to reduce false positives, increase the efficiency of
vulnerability detection, and assist in prioritizing mitigation efforts, adapting to the
needs of developers and organizations.
This document includes a brief review of existing open-source SAST tools, the
development of the platform and the processes for aggregating and enriching results,
and presents the tests performed and the results obtained.
The results obtained demonstrated an improvement in both coverage and accuracy
of vulnerability detection compared to the use of a single tool, with F1-score gains for
categories such as command injection (47.8%) and SQL injection (36.5%) following
the integration of multiple SAST tools and AI-based enrichment
