Design methodologies for smart textile products in the field of sport
Tese de doutoramento em Design de ModaApesar das fortes implicações no campo interdisciplinar da interação humano-computador (HCI), tem
havido um movimento para que a roupa desportiva acolha no seu design inúmeras inovações, tanto nas
tecnologias eletrónicas, como nos materiais e acabamentos. Posicionando-se audaciosamente entre o
design de moda e os dispositivos vestíveis, estas roupas discorrem entre as tecnologias da informação e
comunicação (ICT) e as plataformas da internet das coisas (IoT), trazendo benefícios e funcionalidades,
consequentemente novas características de interação entre a roupa e o utilizador.
Nesse contexto, e no âmbito das atividades do projeto TSSIPRO – Technologies for Sustainable and Smart
Innovative Products, obteve-se o desenvolvimento de conhecimento através de dois estudos de caso, tendo
cada um destes sido acompanhado por um método. O estudo “Smartsuit”, que foi orientado pelo método
Duplo Diamante, teve como foco o ciclismo. Corresponde a um contacto introdutório e multidisciplinar ao
processo de design de vestuário inteligente para o desporto. Permitiu através da experiência empírica,
experimental, pessoal do autor, o design e a prototipagem de um skinsuit com elétrodos integrados capazes
de monitorizar a frequência cardíaca por eletrocardiografia (ECG). O estudo “Avantgarde” foi orientado pelo
método Design Centrado no Utilizador, e teve como foco a esgrima. Corresponde já a uma maturação da
temática e identifica os requisitos do utilizador. Permitiu através da experiência conceptual, teórica,
metódica e organizada do autor, a conceptualização de um uniforme inteligente com sensor de pressão
piezoresistivo flexível integrado no têxtil capaz de capturar o desempenho do toque da arma, facilitando a
arbitragem e pontuação do jogo. Dispõe ainda de sensores inerciais (IMU) acoplados no têxteis capazes de
capturar e rastrear os movimentos do atleta através da transposição do movimento para um modelo digital.
Aqui, foi possível, a seleção e avaliação das tecnologias vestíveis através da agnição de dados quantitativos
e qualitativos fornecidos pelos utilizadores.
Esta tese contribui para o crescente corpo de pesquisa sobre o uso de computadores vestíveis
para a atividade desportiva. Através do utilizador enfatiza-se inovação, usabilidade e design. Mais
especificamente, valida o interesse de atletas e treinadores de esgrima, por tecnologias com sensores
de pressão e inerciais. Ao nível do processo de design possibilitou investigar e avaliar através de dois
modelos destintos e, portanto, identificar as suas diferenças e limitações.Despite the substantial implications in the interdisciplinary field of human-computer interaction (HCI),
there has been a movement for sportswear to embrace numerous innovations in its design, both in
electronic technologies and in materials and functionalisation. Audaciously situated between fashion
design and wearable devices, these clothes roam between information and communications technology
(ICT) and the internet of things (IoT) platforms, bringing benefits and functionalities, consequently new
features of interaction between clothing and the user.
In this context, and within the scope of the activities of the TSSIPRO – Technologies for Sustainable and
Smart Innovative Products, the development of knowledge was obtained through two case studies, each
of which was accompanied by a method. The “Smartsuit” study, which was guided by the Double
Diamond method, focused on cycling. It corresponds to an introductory and multidisciplinary contact to
the process of designing smart garments for sport. Through the author's empirical, experimental, personal
experience, it allowed the design and prototyping of a skinsuit with embedded electrodes capable of
monitoring heart rate by electrocardiogram (ECG). The “Avantgarde” study was guided by the User-
Centered Design method and focused on fencing. It corresponds to a maturation of the theme and
identifies the user's requirements. It allowed, through the author's conceptual, theoretical, methodical,
and organized experience, the conceptualization of a smart uniform with a flexible piezoresistive pressure
sensor integrated into the textile capable of capturing the performance of the weapon's touch, facilitating
the refereeing, and scoring of the game. It also features with inertial sensors (IMU) coupled to the textiles
capable of capturing and tracking the athlete’s movements by transposing the movement to a digital
model. Here, it was possible to select and evaluate the wearable technologies through the analysis of
quantitative and qualitative data provided by users.
This thesis contributes to the growing body of research on the use of wearable computers for sports
activities. Through the user, innovation, usability, and design are emphasized. More specifically, it
validates the interest of athletes and fencing coaches in pressure and inertial sensor technologies. At the
level of the design process, it made possible to investigate and evaluate through two distinct models and,
therefore, identify their differences and limitations.TSSIPRO - bolsa de investigação UMINHO/BI/123/201
A Educação em Saúde na área da Parasitologia: a experiência dos projetos de extensão LiPar e Educac na “Semana de meninas e mulheres na Ciência” ocorrida na Universidade do Estado do Rio de Janeiro
As atividades de extensão universitária têm ganhado cada vez mais espaço, por mostrarem-se importantes instrumentos de construção do pensamento científico, colaborando para a incorporação de novos saberes e práticas para a sociedade e para os extensionistas. Os espaços não formais de ensino, por sua vez, revelam-se ótimos meios para tornar a construção desses saberes possível. Logo, através da associação das atividades de extensão em espaços não formais de ensino, é possível promover as temáticas de educação em saúde em parasitologia, buscando conscientizar e prevenir, de modo criativo e ativo, as parasitoses que ainda são um grande problema de saúde pública. Desta forma, esse trabalho se propôs relatar a experiência dos projetos de extensão da Universidade do Estado do Rio de Janeiro, LiPar (Liga de Parasitologia) e Educac, no evento “Semana de Meninas e Mulheres na Ciência”, organizado por mulheres de diferentes áreas das ciências e tecnologias. Assim, analisou-se de que forma o espaço não formal de ensino pode ajudar na prática educativa das atividades propostas pelas extensões e de que maneira esses projetos levam o conhecimento de educação em saúde em parasitologia nesses espaços. Além disso, por meio da técnica da Nuvem de Palavras, buscou-se identificar as principais dúvidas sobre os assuntos de parasitologia abordados e também as pré-concepções sobre o tema. Portanto, concluiu-seque o espaço não formal institucionalizado pode ser um grande aliado para o ensino de educação em saúde em parasitologia, pois permite utilizar diferentes metodologias que colaboram para a compreensão da teoria com a prática

Rarity of monodominance in hyperdiverse Amazonian forests.
Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates
Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis).
Time period: Tree-inventory plots established between 1934 and 2019.
Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm.
Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield.
Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes.
Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests.
Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types
Geography and ecology shape the phylogenetic composition of Amazonian tree communities
AimAmazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types.LocationAmazonia.TaxonAngiosperms (Magnoliids; Monocots; Eudicots).MethodsData for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny.ResultsIn the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2 = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2 = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.Main ConclusionNumerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions
