This study was an investigation of the influence of using wool felt-based hospital bedding as a way of preventing the incidence of pressure injuries in patients with high risk of developing them. The influence of the number of wash cycles on lipid content, morphology, and mechanical performance of wool felt-based bedding was studied. A combined approach was adopted, including Soxhlet extraction for lipid content analysis, mechanical testing (traction, stretching, and tearing), scanning electron microscopy, and a randomized clinical evaluation in hospitalized patients with high risk. Chemical testing showed a decreasing trend in lipids with the number of washes, reaching a final value of 0.13%. Clinical results showed that the use of wool felt bedding generated a lower incidence of pressure injuries compared with conventional polyester-based bedding (4.2% vs. 12.6%; p = 0.04), along with good patient acceptance. Scanning electron microscopy showed that washing promotes the reorganization of fibers, changing from an initial compact structure to a more open and porous configuration. Mechanical tests indicated that the material presents greater elongation and adequate behavior under tension and rupture stresses, contributing to load redistribution. In the tensile and elongation tests, maximum tensile stress ranged from 4.11 to 6.13 MPa and elongation from 21.8% to 48.9% in the transverse direction; in the longitudinal direction, values ranged from 2.04 to 5.71 MPa and from 21.8% to 48.9%, respectively, for the unwashed condition and after nine wash cycles. In the tear resistance test, strain values ranged from 100% to 166% in the transverse direction and from 54% to 149% in the longitudinal direction, for the unwashed condition and after nine wash cycles, respectively. Analyses of chemical, structural, and mechanical properties suggest that wool felt provides better adaptability to the skin–material interface, reducing localized pressure concentrations. The lipid extraction test showed a trend of decreasing lipid content with the number of washes, reaching a final value of 0.13%; however, the increased porosity (increase in volume) of the material may contribute to greater water adsorption from the environment and consequent skin hydration. Mechanical tests showed that transverse elongation of 50% can contribute to a more efficient entanglement of fibers, resulting in a greater ability to withstand tensile loads. These findings highlight the potential of the material for hospital bedding applications, contributing to pressure injury prevention and improved patient comfort.

O período entreguerras (1918–1939) foi marcado por profundas transformações sociais que alteraram de maneira significativa os papéis sociais desempenhados pelas mulheres. A inserção feminina no trabalho industrial, nos serviços e na vida pública produziu deslocamentos simbólicos importantes, que encontraram no design de moda e no jornalismo espaços privilegiados de representação e negociação. Este artigo realiza uma revisão teórica crítica sobre a construção da imagem da mulher moderna no entreguerras, articulando contribuições da história social, da teoria da moda e do pensamento feminista. A partir do diálogo com Eric Hobsbawm, Gilles Lipovetsky, Simone de Beauvoir e Judith Butler, argumenta-se que a figura da “nova mulher” construída pelo jornalismo de moda, conforme praticado pelas duas principais publicações americanas da área na época – Harper's Bazzar e Vogue, expressa uma emancipação condicionada, marcada por tensões entre liberdade, controle simbólico e padrões normativos de gênero, classe e raça.

Este artigo investiga a modelagem de vestuário plus size, com foco no tamanho 48, e analisa as diretrizes da ABNT aplicáveis a essa área, além das dificuldades enfrentadas por consumidores ao buscar roupas que atendam a suas necessidades físicas e estéticas. Com base em autores como Katz (2012) e Jimenez (2022), o estudo aborda conceitos de representatividade e aceitação corporal, destacando a importância de reconhecer a diversidade de corpos. A metodologia divide-se em duas etapas: a primeira compara tabelas de medidas do tamanho 48 de quatro fontes — manequins da marca Draft, WM Manequins e diretrizes da NBR 16933 para tipos corporais "colher" e "retangular" —, enquanto a segunda realiza uma análise de conteúdo de uma postagem da influenciadora Brenda Avelar no Instagram, que promove a aceitação do corpo e desafia padrões estéticos tradicionais, alinhada às teorias de empoderamento e inclusão de Ribeiro e Matos (2022). Os resultados indicam que, embora haja esforços para adequar as normas, as diretrizes da ABNT ainda precisam de melhorias para atender a um público diversificado, reforçando a importância de considerar as experiências de pessoas com corpos maiores. A pesquisa também revela que a inclusão de corpos gordos no mercado de moda não é apenas uma questão de representatividade, mas também uma oportunidade de mercado em expansão.

Este artigo avaliou como a Gestão do Design vem sendo abordada historicamente em três tradicionais periódicos brasileiros de Design e a relação desses estudos com a Administração Científica. Foram encontrados 37 artigos e foi elaborada uma revisão de literature e uma bibliometria. Percebeu-se que a maioria dos estudos são exploratórios e qualitativos, assim como, que há um distanciamento das publicações em relação à Administração Científica.

This article presents groundbreaking research on wool felt for use in hospital accessories. The results of mechanical, scanning electron microscopy (SEM), chemical, flammability, and microbiological tests are presented, as well as research on the acceptability of three wool felt hospital accessories (i.e. sheet cover, pillowcase cover, and insole). An innovative approach was utilized to compare the mechanical properties of unwashed and washed wool felt samples by three different washing machines, with textiles commonly used in hospital (i.e. nonwoven of polyester felt, woven of 100% cotton, and woven of a blend of 67% cotton and 33% polyester). The mechanical tests showed that the wool felt had tensile resistance similar to that of polyester felt, superior elongation to the 100% cotton and the blend, inferior tearing stress, lower resistance to slippage, and good pilling resistance. After washing, the wool felt washed with the extractor washer and dry washer increased their tensile strength 33% and 19%; the tear strength did not change; the slippage decreased; and the samples washed with the dry washer showed 14% less pilling than those not washed. The SEM tests showed differences in appearance of the fibers after the washing processes. Chemical tests revealed that 0.11% of lanolin was retained in the wool felt after washing the samples with the dry process. The flammability tests showed the dependence of carbonization length with the wool felt washing process. The volunteers showed a good acceptance of the wool felt accessories emphasizing the feeling of freshness, release of pain, and reduction in sweating and unpleasant odors. Microbiological tests showed growth in the insoles of the bacterium Staphylococcus aureus and the fungus Candida albicans, commonly found in the hospital environment.
