Observabilidade em DevSecOps: Visualização de Dados de Segurança de Aplicações Web
No full textO crescimento excecional do número de atividades de cibercrime que exploram as
vulnerabilidades existentes em aplicações Web reforçou a necessidade das organizações em
fortalecerem as suas políticas de segurança em vigor durante o ciclo de vida de
desenvolvimento de software – SDLC. Para suprir esta necessidade surgiu o conceito de
DevSecOps, que implementa práticas e testes de segurança, realizados por scanners
automáticos, durante todo o SDLC. Estes scanners possuem meios para reportar as
vulnerabilidades identificadas, mas geralmente apresentam funcionalidades limitadas para
representar essa informação de forma visual.
Este documento apresenta a descrição de uma solução desenvolvida no âmbito de um estágio
curricular realizado em ambiente empresarial. A solução permite a extração, integração e
visualização de dados relevantes e constantes nos relatórios de diversos tipos ferramentas de
segurança. Os dados extraídos e integrados são apresentados graficamente, por meio de um
dashboard interativo e customizado, explorando os conceitos associados à visualização de
dados. São descritas todas etapas de desenvolvimento desta solução, desde o processo de
extração de dados até ao desenvolvimento do dashboard.
A análise comparativa efetuada demonstra que a solução se destaca das soluções
semelhantes, devido à sua capacidade de integração e apresentação de dados de múltiplos
tipos de ferramentas de segurança num dashboard unificado, contrariamente às restantes,
que se focam em tipos específicos de ferramentas de seguranças. Esta abordagem
proporciona uma visão geral do estado da segurança das aplicações e uma análise detalhada
das vulnerabilidades existentes.
O contributo principal desta solução reside na melhoria do processo de monitorização e
avaliação do estado de segurança das aplicações desenvolvidas, fornecendo insights valiosos
para a organização. Esses insights auxiliam na tomada de decisões sobre a implementação
de medidas e protocolos de segurança no SDLC. Este contributo foi corroborado pela
realização de um inquérito SUS, que confirma a validade da solução desenvolvidaThe exceptional rise in cybercriminal activities exploiting web application vulnerabilities
has intensified the need for organizations to strengthen their security policies throughout the
Software Development Life Cycle (SDLC). The concept of DevSecOps emerged to address
this issue, integrating security practices and automated security testing using scanners
throughout the entire SDLC. These scanners have mechanisms for reporting identified
vulnerabilities but have limited capabilities for visually representing this information in
general.
This document presents the description of a solution developed as part of a curricular
internship, conducted in a corporate environment. The solution enables the extraction,
integration and visualization of relevant data contained in reports from several types of
security tools. The extracted and integrated data are presented graphically through an
interactive and customizable dashboard, leveraging concepts associated with data
visualization. All development stages of this solution are described, from the data extraction
process to the dashboard implementation.
The comparative analysis conducted demonstrates that this solution stands out from similar
alternatives due to its ability to integrate and present data from multiple types of security
tools in a unified dashboard, unlike existing solutions that focus on specific types of security
tools. This approach provides an overall view of the security status of applications, offering
a detailed analysis of existing vulnerabilities.
The main contribution of this solution lies in improving the process of monitoring and
assessing the security status of developed applications, providing valuable insights for the
organization. These insights support decision-making regarding the implementation of
security measures and protocols throughout the application development cycle. This
contribution was validated through a SUS survey, which confirms the effectiveness of the
developed solutio

GreenCanvas: 3D Model Plant Generator System Based on Drawings
No full textThe generation of three-dimensional plant models is increasingly important for applications
in agriculture, scientific visualization, landscape design, and immersive virtual
environments. Existing approaches often rely on specialized hardware or sensor data,
and publicly available models are limited, repetitive, or constrained to specific species,
limiting creative flexibility. This dissertation addresses these challenges by focusing
on sketch-based plant modelling as an accessible and flexible approach.
A systematic review of state-of-the-art methods was conducted following the Preferred
Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines,
identifying two main directions: sketch-based modelling and tree generation
from photographic data. Insights from this review informed the design of a novel
framework that integrates single- and multi-sketch strategies to generate 3D plant models
from user drawings. The framework was implemented as a Blender add-on, supporting
features such as variable levels of detail, leaf propagation, and generation of
multiple model variations, while providing a streamlined and intuitive interface.
The add-on was evaluated through quantitative and qualitative analyses. Task completion
times demonstrated efficient modelling, and a mean System Usability Scale
(SUS) score of 56.4 indicated moderate usability. Correlations with demographic factors
revealed influences of user experience, background, and familiarity with input devices
on usability. Qualitative feedback highlighted areas for improvement in feature
intuitiveness and onboarding. Despite a limited and unevenly distributed participant
sample, the results indicate that the framework is a promising tool for procedural plant
modelling and can enhance creative workflows for users of varying expertise.
This work contributes both a systematic understanding of visual-based plant modelling
approaches and a practical tool that bridges sketching and 3D model creation,
providing a foundation for future enhancements such as AI-assisted sketch interpretation,
expanded plant element support, and improved interface features
Gender Equality and Stock Returns
No full textThis dissertation examines the relationship between gender equality in corporate governance and stock market performance in the European context. Motivated by the growing relevance of diversity in corporate boards and its recognition within Environmental, Social and Governance (ESG) frameworks, the study explores whether gender equality is associated with superior stock returns. The analysis focuses on publicly listed companies in the STOXX Europe 600 index between 2014 and 2024, a period marked by important regulatory developments, including the European Union Directive on Gender Balance in Corporate Boards.
The research adopts a quantitative, explanatory, and correlational design. Firm-level data on board gender composition were collected from LSEG Workspace (LSEG Data & Analytics), while financial data were obtained from Datastream. The empirical analysis employs panel data regressions to estimate the impact of gender equality on both raw returns and risk-adjusted returns, the latter calculated through Capital Asset Pricing Model (CAPM) and the Fama-French three- and five-factor models. Control variables such as firm size, leverage, book-to-market ratio, and beta were included, and robustness checks were conducted to validate the results.
The findings indicate that gender equality on boards, measured by the percentage of women directors, does not exert a statistically significant effect on stock returns. Although the coefficients often show a positive direction, the results suggest that gender diversity is not yet perceived by investors as a direct driver of financial market performance in the short term. Instead, stock returns appear to be more strongly influenced by traditional firm-level and market factors. These results align with prior studies reporting neutral or inconclusive effects of gender diversity on financial outcomes, while reinforcing the broader value of gender equality for governance, legitimacy, and long-term sustainability

Seeking Something Beyond Themselves: A Concept Analysis of Spiritual Awakening Experiences at the End of Life
No full textArticle number - 358Background/Objectives: End-of-life (EoL) experiences are critically important for everyone involved, giving rise to a set of needs that extend far beyond bio-physiological aspects, to encompass the spiritual dimension as the core of human beings. Understanding the processes of spiritual awakening (SA) assists palliative care professionals in enhancing the quality of care provided to individuals with life-threatening illnesses, as well as to their families. SA is a fundamental occurrence linked to the fulfilment of our spiritual needs when facing an existential crisis, such as the proximity of death. However, its conceptual boundaries need to be clarified to provide qualified and humanized palliative care. Therefore, this study aims to identify the key attributes, antecedents, consequents, and empirical referents of SA at EoL, as well as to clarify the concept’s existing ambiguities. Methods: Walker and Avant’s eight-step concept analysis was used. A literature search was conducted in May 2025 across three databases (PubMed, CINAHL and Scopus). Results: Following the review, 21 articles were included for analysis. The concept analysis revealed four main attribute domains: (1) sensory–perceptual domain; (2) affective/cognitive domain; (3) relational domain; and (4) transcendental domain. Moreover, spiritual consciousness and the existential matrix were antecedents to this concept; revaluation of beliefs, finding spiritual serenity and inner freedom, fostering spiritual growth, and the desire to leave a legacy were its consequences. Conclusions: The concept of SA at the EoL reveals itself to be a complex and multifactorial phenomenon, with a profound impact on a person’s confrontation with finitude. Recognizing and integrating SA into palliative care allows for a more comprehensive understanding of human consciousness. To deal with SA experiences in healthcare settings, a multifaceted approach is needed. This encompasses acknowledging spirituality as a determinant of health, including spiritual care in standard practice, and offering education and training on spiritual care competence for healthcare practitioners. Further transdisciplinary research should be undertaken to explore SA phenomenological variations, guide clinical interventions, and evaluate SA impacts on spiritual well-being and spiritual growth.It was also supported by FCT—Fundação para a Ciência e a Tecnologia, I.P.

O Impacto da Descentralização Administrativa na Capacidade de Resposta das Unidades Locais de Proteção Civil: Perspetivas para o aperfeiçoamento das políticas públicas e de proteção
No full textA presente dissertação analisa o impacto da descentralização administrativa na capacidade de resposta das Unidades Locais de Proteção Civil (ULPC) em Portugal, com particular incidência na Região de Leiria. Partindo da reorganização administrativa das freguesias e da recente reestruturação da Proteção Civil, pretende-se procurar compreender de que formas a proximidade administrativa e a autonomia local influenciam a eficácia, rapidez e coordenação das respostas em situações de emergência. A investigação adotou uma metodologia qualitativa com recurso a entrevistas semiestruturadas, análise documental e revisão legislativa, permitindo identificar os principais desafios enfrentados pelas ULPC, tais como a escassez de recursos, a falta de regulamentação uniforme e a articulação entre níveis de governação.
Os resultados obtidos evidenciam que, apesar dos avanços proporcionados pela descentralização, persistem limitações significativas na implementação e funcionamento das ULPC, especialmente no que se refere à sua integração no sistema nacional de Proteção Civil, formação e comunicações. A investigação permitiu ainda identificar boas práticas locais que, se replicadas e apoiadas institucionalmente, poderão contribuir para o reforço da resiliência territorial e para a construção de políticas públicas mais eficazes e alinhadas com as necessidades das comunidades. Conclui-se que um modelo híbrido, que combine autonomia local com coordenação central, poderá ser o caminho mais promissor para uma Proteção Civil mais eficaz, participativa e sustentável.his dissertation examines the impact of administrative decentralization on the response capacity of Local Civil Protection Units (ULPC) in Portugal, with a particular focus on the Leiria Region. Starting from the administrative reorganization of parishes and the recent restructuring of the civil protection system, the study aims to understand how administrative proximity and local autonomy influence the efficiency, speed, and coordination of emergency responses. The research followed a qualitative methodology, using semi-structured interviews, document analysis, and legal review to identify the main challenges faced by ULPCs, such as limited resources, lack of standardized regulations, and the coordination between governance levels.
The findings show that, despite the progress achieved through decentralization, significant limitations persist in the implementation and operation of ULPCs, particularly regarding their integration into the national civil protection system, training and network communications. The study also identifies local best practices which, if institutionally supported and replicated, could strengthen territorial resilience and support the development of more effective public policies aligned with community needs. The conclusion suggests that a hybrid model, combining local autonomy with centralized coordination, may offer the most promising path for a more effective, participatory, and sustainable civil protection framework
Deep Eutectic Systems: A Game Changer for Marine Bioactives Recovery
No full textThe extraction of bioactive compounds from marine natural products has gained increasing attention due to their diverse applications, such as in pharmaceuticals, nutraceuticals, and cosmetics. Yet, low extraction yields and toxicity associated with common solvents are a major bottleneck. Deep eutectic solvents (DESs) and natural deep eutectic solvents (NADESs) have emerged as promising green alternatives to conventional organic solvents, offering advantages such as biodegradability, greater environmental and economic sustainability, low toxicity, and enhanced extraction selectivity. This review provides a comprehensive analysis of the principles, physicochemical properties, and applications of DESs/NADESs to obtain bioactive compounds from marine organisms. Among the most recent works, it is possible to verify the success of NADESs to extract carrageenan from the seaweed Kappaphycus alvarezii; pigments from Palmaria palmata; and polyphenols and proteins from different brown seaweeds. NADESs have also shown high potential to extract other valuable compounds from marine by-products, such as chitin from crabs and shrimp shells, and also lipids and proteins from different fish species and protein rich extracts from tilapia viscera. The challenges for DESs/NADESs use at industrial scale are also discussed, and success cases are revealed, highlighting their potential as game changers for extracting bioactive compounds from marine organisms and driving the development of innovative biotechnological products.This work was supported by the Portuguese Foundation for Science and Technology (FCT) through the Strategic Projects granted to the MARE—Marine and Environmental Sciences Centre—(DOI 10.54499/UIDP/04292/2020 and DOI 10.54499/UIDB/04292/2020), to the Associate Laboratory ARNET (DOI 10.54499/LA/P/0069/2020), and the SEA-UP project (https://doi.org/10.54499/2023.13029.PEX).
