Why refashion? Fashion, poetics and hybridisation of creative methods for a sustainable future

Publication . Pardo Cuenca, Desamparados; Broega, Ana Cristina; IPCB. ESART

Abstract : Although in the last 10 years collaborative design and design for sustainability processes have been increasingly used, there is still a great of lack of knowledge and precision in the development of precise collaborative methodologies and holistic applications of sustainable hybrid techniques that favor the development of co-creative and gen-erative circular processes. The paradox of fast fashion and the pursuit of modernity, coupled with the need to care for the earth's resources in a sustainable manner that includes social, economic and environmental impacts, is a difficult dilemma to solve. Some studies have proposed exploring upcycling circular design processes; however, their methodological limitations and the absence of a clear and oriented design thinking process restrict them to seek the inspiration from textile waste in an artisanal perspective. These development processes are often imprecise in their methodology and accidental in their creation process, which generates little credibility, communicative secu-rity and didactic replication in the classroom. In addition, the lack of precision and fine-tuning brings them closer to artisanal technical methods, lacking rigorous narrative logic and holistic de-sign thinking. This research explored the design for sustainability processes, focusing on finding collaborative methodologies of rigorous design thinking that would help students explore and strengthen their individual and group identities by applying sustainable hybridization techniques throughout the design process. The focus was on how we educate designers for a sustainable and collaborative future. We built a collaborative methodological conceptual model of sustainable approach that was tested in different projects over different academic years. The results demonstrate that the implementation of collaborative meth-odologies with sustainable approaches in the ap-plication of specific eco-design techniques and the construction of a group identity based on research, assignment analysis, and the use of creative techniques and tools that generate reflec-tive learning contribute to the collaborative methodologies and to the effective implemen-tation of this methodology in the teachings of fashion design with a circular approach.

Amazônia brasileira: o legado da cultura portuguesa colonial nos trópicos, valorizado por meio do design estratégico

Publication . Lobo, Francisco Assis Sousa; Silva, João Carlos R. Plácido da; Botura Júnior, Galdenoro; IPCB. ESART

A difusão do turismo no Brasil favorece o desenvolvimento econômico em diversas regiões, repercutindo, de modo considerável nos estados que integram a Amazônia legal. Porém no estado do Maranhão, o segmento destinado à visita do acervo arquitetônico e urbanístico colonial, tem retraído com a procura por locais de beleza natural. O trabalho contribuiu para a valorização do legado histórico através do desenvolvimento de projeto gráfico, com o objetivo de incentivar a visita dos monumentos turísticos na cidade de São Luís. Foi aplicada a metodologia de design, “painel semântico do público-alvo. As zonas urbanas com potencial de visita turística, foram identificados e estabelecidos dois roteiros para a visita do patrimônio oriundo da colonização portuguesa. Para cada monumento escolhido, foi desenvolvido um carimbo de visita com características próprias do lugar, possíveis de serem aplicados também em souvenires. Os resultados foram analisados conforme os parâmetros de Clive Ashwin (1979), seguindo as diretrizes definidas por Lócio (2019). Apesar dos resultados não terem sido implantados, é notório que podem incentivar a visita e contribuir com a economia local

Emotional colour paletteof visually impaired individuals throughsense of touch in daily wear garments

Publication . Sharma, Deepshikha; Pereira, Carla Costa; IPCB. ESART

The sense of touch elicits various flows of thoughts and feelings unique to everyone specifi-cally for visually impaired individuals. It shows in different research that different emotions arise in response to touching various textures. This research paper attempts to delve intothe diverse emotional experiences of visually impaired individuals when they interact with different-coloured fabrics through tactile sen-sation. Despite their visual impairment, these individuals possess a keen sensory ability to discern textures of different types of fabrics in daily wear garments. This research is using user experience methodology and questionnaire method (5-point Likert scale tool) for the col-lection of the data. The primary focus lies on elucidating the emotional impact of design on the daily lives of visually impaired individuals. The author selects fabrics, including a 100% Viscose T-shirt in white and black, 100% poly-ester T shirt in beige and green, 100% cotton T-shirt in yellow and blue and 100% Linen casual wear shirt in white and each fabric cat-egory maintains consistent quality. The Plutchik Wheel of Emotions is using in this research to select emotions, specifically focusing on the 8 basic emotions. Memory, cultural associations, and individual preferences also significantly influence the emotional experiences in tactile fabric perception. The results indicate that the 100% linen casual wear shirt in white and black evokes the same loathing emotion, while the 100% cotton T-shirt in yellow elicits ecstasy, with blue prompting admiration. The 100% polyester T shirt in beige and green also induces ecstasy but the level of ecstasy is more in green. Additionally, the 100% viscose T-shirt in black and white triggers ecstasy, with the highest intensity ob-served in the white T-shirt. These findings give the emphasize and connection between tactile sensation, fabric properties, and emotional responses in visually impaired individuals.

A global review of cheese colour microbial discolouration and innovation opportunities

Publication . Ferraz, Ana Rita; Pintado, Cristina Santos; Serralheiro, Maria Luísa

Cheese is a biologically active food product, characterised by its colour, texture, and taste. Due to its rich matrix of fats and proteins, as well as the fact that the cheese’s surface acts as its own packaging, the cheese becomes more susceptible to contamination by microorganisms during the ripening process, particularly bacteria and fungi. The ripening of cheese involves several biochemical reactions, with the proteolytic activity of the cheese microbiota being particularly significant. Proteolysis results in the presence of free amino acids, which are precursors to various metabolic mechanisms that can cause discolouration (blue, pink, and brown) on the cheese rind. Surface defects in cheese have been documented in the literature for many years. Sporadic inconsistencies in cheese appearance can lead to product degradation and economic losses for producers. Over the past few decades, various defects have been reported in different types of cheese worldwide. This issue also presents opportunities for innovation and development in edible and bioactive coatings to prevent the appearance of colour defects. Therefore, this review provides a comprehensive analysis of cheese colour globally, identifying defects caused by microorganisms. It also explores strategies and innovation opportunities in the cheese industry to enhance the value of the final product.

Influence of Cynara cardunculus L. phenolic compounds on Pseudomonas putida isolated from the dairy industry: Growth and melanin bioproduction

Publication . Ferraz, Ana Rita; Pintado, Cristina Santos; Serralheiro, Maria Luisa

Cynara cardunculus L. inflorescence infusion has been used for several centuries as curd in traditional cheese making, such as some highly prized Portuguese cheeses. To promote thesustainable use of all C. cardunculus plants, C. cardunculus extract leaves decoction (CL), inflorescence decoction (CI), chlorogenic acid (CA) (a compound in the plant leaves), and rosmarinic acid (RA) (a similar phenolic compound) solutions were tested for antimicrobial activity against bacteria that may appear on the cheese rind. The antimicrobial activity was evaluated by 15 bacterial strains using two different methodologies: solid and liquid. The influence of these extracts and the phenolic compounds on melanin bioproduction by Pseudomonas putida ESACB 191 was also studied. CA and RA (1 mg/mL) showed antimicrobial activity. CL and CA reduced P. putida ESACB 191 growth in the liquid assay and melanin bioproduction by 6.20 Log CFU/mL and 50%, respectively. Cynarin, CA, and its derivates were identified as the main phenolic compounds (52%) of CL, which may justify its inhibitory action on bacterial growth and melanin bioproduction. Thus, future perspectives include the application of CL extracts with antimicrobial activity in edible films and/or coatings to applied in cheese rind to increase the shelf time.
