Ao longo do percurso, aplicou-se uma metodologia mista, pois o processo começa com uma metodologia não intervencionista e posteriormente incide-se uma metodologia intervencionista.Abstract: This internship report, within the field of Fashion Design, reflects the learning acquired by the master's student through her experience as a fashion designer at an independent brand. The internship lasted for 5 months, starting on 02/11/2023 and ending on 29/03/2024, at the Duarte Hajime brand, based in Lisbon, Portugal. This brand aims to redefine the concept of Streetwear, creating a cool and urban lifestyle by combining design, innovation, and sustainability. Throughout this experience, the main objective was to consolidate the academic knowledge gained, turning it into practical and conclusive applications within the business and multidisciplinary environment of design, facilitating the acquisition of professional experience. The relationship between fashion and sustainability has become increasingly intertwined. In recent years, however, there has been a growing movement of designers advocating for more sustainable fashion, raising awareness about how fashion is produced, consumed, and discarded. Thus, the master's student explored the sustainable and innovative aspect of the DUARTE HAJIME brand. During the internship, she had the opportunity to interact and work with experienced professionals in the fashion industry, directly observing the stages involved in the creative and production processes of clothing. Furthermore, she had the opportunity to analyze the marketing and communication strategies applied by DUARTE HAJIME to highlight its initiatives to consumers, fostering strong and cohesive awareness of responsible fashion. This report is divided into four chapters. Chapter 1 specifies the theme, research questions (main and secondary), objectives (general and specific), and the research framework. Chapter 2 presents the theoretical framework, analyzing all topics related to the internship practice. Chapter 3 provides an in-depth presentation of the Duarte Hajime brand. Then, Chapter 4 reports on the entire experience and projects carried out during the professional internship. It contributes to the report by presenting a technical catalog and a technical sheet. Finally, in Chapter 5, conclusions are drawn. However, the main objective of this internship was to provide the master's student with real-world experience in the fashion industry, expanding her knowledge and skills as a fashion designer by actively participating in the operational dynamics of the DUARTE HAJIME brand. A mixed methodology was applied throughout this report, starting with a non interventionist methodology, later shifting to an interventionist methodology

    Abstract: The aim of this study was to see if there are any associations between mental health, Body Mass Index (BMI), and physical exercise (PE) in young Por tuguese adults. The sample consisted of 414 people aged between 18 and 25 years old. A sociodemographic questionnaire designed for this study and the Mental Health Inventory were used. To analyze the results, the total sample was divided according to the criteria “BMI ≥ 5 kg/m2”; “BMI < 25 kg/m2”; “does not practice PE”; and “practices PE”, and sample groups were formed with these names. It was found that there was an association between the dimensions of the Mental Health Inventory and the average time spent practicing PE in the total sample (r from 0.099 to 0.160) and in individuals with a BMI < 25 kg/m2 (r = 0.154 and 0.169). In individuals with a BMI ≥25 kg/m2, there was an association between the ‘BMI’ and depression variables (r = −0.174). In all groups, associations were found between the variables of age and BMI (r from 0.120 to 0.216). There was also a significant effect of group (non-exercise vs. exercise groups) on the dependent variables, Λ = 0.972, F(5, 408) = 2.329, p = 0.042, η2p = 0.28. This study confirms the association between PE and mental health and suggests that BMI may have an influence on the appearance of depressive symptoms in young Portuguese adults

    Precision agriculture aims to detect differences in plant development within adefined area, allowing to adjust production techniques according to the plantdevelopment. Plant development is evaluated by remote detection allowing theapplication of variable rate application techniques. The efficiency of precisionagriculture is correlated with large areas of the same crop where plantsdevelopment is highly correlated with soil characteristics variation. Theapplication of precision agriculture in fruit production is common in the speciesthat allow mechanical harvesting, and, consequently, allows obtaining yieldmaps. Peach production is carried out by manual harvesting and is usuallybased on medium-sized parcels, as the fruit is very perishable and harvestwindow for each cultivar is short, from 10 to 15 days. This paper describes theexperimental tests developed to evaluate the volume of peach tree canopy,based on images captured by a drone, and its correlation with trunk sectionarea, which is a common way of assessing tree vigor. Ten plants per orchardwere monitored in 20 different orchards. The correlation between tree canopyand nutritional status was developed using the orchard as the repeating unit.The results indicate that projected canopy area, evaluated by aerial images, isdirectly correlated with tree canopy volume, in full developed orchards, as treeheight is standardized in every orchard according to the training system. Theremote assessment of the tree canopy allows the adoption of differentiatedtechniques that contribute to better management focused on a greater incometo the farmer and, at the same time, contribute to environmental sustainability

    Are the cross-culturally adapted versions of the Tampa Scale for Kinesiophobia 11-item valid, reliable, and responsive? A COSMIN-informed systematic review of measurement properties

    Numerous cultural adaptations of the Tampa Scale of Kinesiophobia 11-item version (TSK-11) scale have emerged since the original version was introduced. We conducted a (COnsensus-based Standards for the selection of health Measurement INstruments) COSMIN-informed systematic review of measurement properties to identify the cross-cultural adaptation of the TSK-11 and report, critically appraise, and systematize its measurement properties. Six databases were searched for studies published since 2005. Studies reporting on the measurement properties of culturally adapted versions of the TSK-11, published in English, Portuguese, and Spanish, were considered for inclusion. The results were synthesized by measurement properties and rated against the COSMIN criteria for good measurement properties. The quality of the evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach and presented in a summary of findings table. Twenty-three studies were included, and cultural adaptations for 15 languages were identified: English, Chinese, Cantonese, Swedish, German, Dutch, Arabic, Turkish, Danish, Spanish, Japanese, Brazilian Portuguese, Marathi, Thai, and Persian. There is “high” certainty in the evidence for “sufficient” criterion validity (TSK-17, r = .84) and “insufficient” measurement error (small detectable change range 5.6–6.16). “Moderate” certainty in the evidence for “sufficient” construct validity (87.8% of hypotheses confirmed), test-retest reliability (intraclass correlation coefficient2,1 = .747–.87), and “low” certainty in evidence for “sufficient” responsiveness. The numerous sources of heterogeneity prevent conclusions from being drawn regarding structural validity. Measurement error, responsiveness, and structural validity of the TSK-11 require further investigation. Clinicians should complement the use of TSK-11 with other instruments. Future studies on the structural validity of the questionnaire should standardize the data analysis methods.info:eu-repo/semantics/acceptedVersio

    Enhancing sustainability in agriculture has become a significant challenge today where in the current context of climate change, particularly in countries of the Mediterranean area, the amount of water available for irrigation is becoming increasingly limited. Automating irrigation processes using affordable sensors can help save irrigation water and produce almonds more sustainably. This work presents an IoT-enabled edge computing model for smart irrigation systems focused on precision agriculture. This model combines IoT sensors, hybrid machine learning algorithms, and edge computing to predict soil moisture and manage Controlled Deficit Irrigation (CDI) strategies in high density almond tree fields applying reductions of 35% ETc (crop evapotranspiration). By gathering and analyzing meteorological, humidity soil, and crop data, a soft ML (Machine Learning) model has been developed to enhance irrigation practices and identify crop anomalies in real-time without cloud computing. This methodology has the potential to transform agricultural practices by enabling precise and efficient water management, even in remote locations with lack of internet access. This study represents an initial step toward implementing ML algorithms for irrigation CDI strategies

    The authors gratefully acknowledge the financial support of La Caixa Foundation through the project “GeoMatRe: Remediação de massas de água afetadas por drenagem de mina” - PV20-00006 and IES, through the contract with FCT (Foundation for Science and Technology) Project FCT—UIDB/04674/2020.The GeoMatRe project aims to find low-cost solutions for water and sediment rehabilitation using raw geomaterials, in abandoned mines of the Iberian Pyritic Belt. One of our case studies is the Caveira mine in southwestern Portugal, where large piles of mining waste, containing significant amounts of metals, record the long history of its exploitation for gold (Au) and silver (Ag). After the exhaustion of its reserves, the extraction of the remaining metals (cooper (Cu), lead (Pb) and zinc (Zn)) and sulphur (S) continued, until its abandonment during the 60s of 20th century. This work has two objectives: (i) to study the influence of mine and mine tailings drainage on water quality by analysing the dissolved and particulate material in drainage waters, and (ii) to determine whether there are differences in the contamination level of these waters according to the different weather conditions of the last two winters.Resumo: O projeto GeoMatRe tem como objetivo encontrar soluções de baixo custo para a remediação de águas e sedimentos utilizando geomateriais, em minas abandonadas da Faixa Piritosa Ibérica. Um dos nossos casos de estudo é a mina de Caveira, no sudoeste de Portugal, onde grandes quantidades de resíduos mineiros acumulados, contendo quantidades significativas de metais, registam a longa história da sua exploração de ouro (Au) e prata (Ag). Após o fim das suas reservas, a extração dos restantes metais (cobre (Cu), chumbo (Pb) e zinco (Zn)) e enxofre (S) continuou, até ao seu abandono durante os anos 60 do século XX. Este trabalho tem dois objetivos: (i) estudar a influência da drenagem da mina e dos rejeitos mineiros deixados ao abandono, sobre a qualidade da água, através da análise do material dissolvido e particulado nas águas de drenagem, e (ii) determinar se existem diferenças nos sues níveis de contaminação em função das diferentes condições meteorológicas dos dois últimos Invernos.N/

    The authors would like to thank the teams at CRAS-HVUTAD, CRASSA and PBG for their cooperation in collecting the samples. We are also very grateful to the Microbiology and Infectious Diseases Laboratory of the School of Medicine and Biomedical Sciences (ICBAS), University of Porto. Sérgio Santos-Silva thanks Fundação para a Ciência e a Tecnologia (FCT) for their financial support of his PhD work under the scholarship 2021.09461.BD contract through the Maria de Sousa 2021 program. Jaqueline T. Bento was supported by the project PRR-C05-i03-I-000190—RumiRes: Epidemiological Surveillance and Awareness of Antimicrobial Resistance and Drug Residues in Small Ruminants in the Central Region.Wild birds may be involved in the transmission of agents of infectious diseases, including zoonoses, a circumstance which raises a number of public and animal health issues. Migratory bird species play a significant role in the introduction of tick-borne pathogens to new geographic areas, contributing to the dissemination of various etiological agents. This preliminary study aimed to assess the occurrence of four potentially zoonotic pathogens (Hepatozoon spp., Borrelia spp., Babesia spp. and Theileria spp.) in the wild birds of Portugal. Blood and tissue samples were taken from 103 birds admitted at wildlife rehabilitation centers. Through the use of conventional PCR, our findings indicate no evidence of the circulation of these pathogens among the studied bird populations in the region. In the One Health context, it is relevant to understand how faraway avian populations play a role in the epidemiology of infectious diseases. Further molecular studies are needed to deepen the knowledge of avian piroplasmosis, borreliosis and hepatozoonosis.This work was supported by projects UIDB/00772/2020 (doi: 10.54499/UIDB/00772/2020) and LA/P/0059/2020, funded by the Portuguese Foundation for Science and Technology (FCT)

    Hybrid B5G-DTN architecture with federated learning for contextual communication offloading

    No full text
    In dense urban environments and large-scale events, Internet infrastructure often becomes overloaded due to high communication demand. Many of these communications are local and short-lived, exchanged between users in close proximity but still relying on global infrastructure, leading to unnecessary network stress. In this context, delay-tolerant networks (DTNs) offer an alternative by enabling device-to-device (D2D) communication without requiring constant connectivity. However, DTNs face significant challenges in routing due to unpredictable node mobility and intermittent contacts, making reliable delivery difficult. Considering these challenges, this paper presents a hybrid Beyond 5G (B5G) DTN architecture to provide private context-aware routing in dense scenarios. In this proposal, dynamic contextual notifications are shared among relevant local nodes, combining federated learning (FL) and edge artificial intelligence (AI) to estimate the optimal relay paths based on variables such as mobility patterns and contact history. To keep the local FL models updated with the evolving context, edge nodes, integrated as part of the B5G architecture, act as coordinating entities for model aggregation and redistribution. The proposed architecture has been implemented and evaluated in simulation testbeds, studying its performance and sensibility to the node density in a realistic scenario. In high-density scenarios, the architecture outperforms state-of-the-art routing schemes, achieving an average delivery probability of 77%, with limited latency and overhead, demonstrating relevant technical viability
