Hybrid Decorative Elements Inspired by Textile Heritage for Furniture: Design and Influence of Coating on the UV-Accelerated Aging Behavior

Integrating traditional textile heritage into contemporary furniture design offers an innovative way to preserve cultural identity through modern materials and decorative techniques. This study investigates the color stability of hybrid decorative plywood panels fabricated using mechanical perforation and sewing techniques inspired by traditional textile motifs. The samples were evaluated using UV-induced artificial aging, alongside color measurements before and after exposure, microscopic analysis, and Fourier Transform Infrared Spectroscopy (FTIR). The approach enables traditional decorative patterns to be transferred onto wood-based materials, creating contemporary furniture decorations, while preserving and reinterpreting the textile heritage. Results revealed distinct aging behaviors depending on the finishing system. Changes in total color difference (ΔE*)—4.36 for red thread, 4.21 for unvarnished reference, 3.34 for oiled, 0.72 for water-based, 2.55 for nitrocellulose-based, and 0.52 for epoxy-coated samples—demonstrated that both the coated plywood substrate and the textile thread were affected by aging after 72 h of UV exposure. Epoxy resin and waterbased coatings provided the greatest color surface stability, while oil- and solvent-based finishes exhibited varying degrees of chromatic alteration due to their different responses to ultraviolet radiation and moderate temperature. The stitch technique showed good structural compatibility with plywood and preserved the integrity of heritage-inspired motifs after artificial aging for 72 h of UV exposure relative to long-term furniture use, which is a limitation of the present study. However, the red cotton sewing thread was more sensitive to light exposure, showing a slight UV-induced discoloration, with effects varying according to coating type. FTIR investigations demonstrated that UV aging of the cotton thread resulted in some photo-oxidative degradation of cellulose, which may explain the minor incipient microstructural degradation phenomena observed by SEM.

Indicators of strength, oxidative stress, and muscle damage in Paralympic powerlifting athletes undergoing variable resistance training
(SPRINGER, 2026-08-27) Georgian Badicu
Introduction Variable resistance strength training (VRT) has been gaining notoriety in the physical preparation of Paralympic Powerlifting (PP) athletes. PP is a strength sport and training tends to increase levels of Oxidative Stress (OS) and Muscle Damage (MD). Objectives This study aimed to analyze the use of chains as a training method with variable resistance (TRV) and the traditional method with invariable resistance (TRAD) on peak torque (PT), rate of torque development (RTD), biomarkers of oxidative stress (EO), and muscle damage (MD) after a PP training session. Methods Fourteen PP athletes were analyzed, age (28.00 ± 5.64), body weight (82.00 ± 23.93), and 1RM (141.43 ± 47.43). The study was carried out in three consecutive weeks: in week (1), the familiarization and 1RM test occurred, and in weeks (2) and (3) in the pre- and post-training moments (immediately after, 24 h and 48 h after), the PT, RTD, EO, and DM were evaluated. The training consisted of five sets of five repetitions at 80% of 1 Repetition Maximum (1-RM) in the bench press. Results For PT, there was an intraclass difference with the use of the chains between the moment before (462.73±94.23) and the moment after (368.48±119.47, “a” p=0.004), and between the moment after (368.48±119.47) and 48 h (444.96±111.25, “b” p=0.027, η2p=0.309, high effect). There was a difference at the moment after between traditional training (440.98±116.38) and with the use of chains (368.48±119.47, “c” p=0.022). There was also a difference between the traditional (500.99±103.67) and with chains (420.36±114.84, “d” p=0.004) at the 24 h time point. There was also a difference at the 48-h time point between the traditional (502.90±122.89) and chains (444.96±111.25, “e” p<0.001, η2p=0.561, very high effect). In the RTD, there was an intraclass difference, with chains, between the time point before (7721.21±4490.67) and the time point 24 h (12,101.89±5070.36, “a” p=0.005, η2p=0.132, moderate effect). And interclass difference, at 24 h, between the traditional (7915.32 ± 4486.39) and chains (12,101.89 ± 5070.36, “b” p = 0.002) and also at 48 h, where a difference was observed between the traditional (8187.01 ± 4903.53) and chains (12,133.42 ± 6399.98, “c” p = 0.016, η2p = 0.452, high effect). The traditional group showed a significant increase in sulfhydryl (SH) production between the pre- and post-moments, and between the post and 48 h after moments. In the LDH group, there was a significant difference only at 24 h after the use of chains and traditional training. Conclusion The variable resistance training (VRT) promoted greater muscle fatigue when compared to traditional training (TRAD) when observing the strength indicators and the biomarkers of EO and DM were positively influenced by training, regardless of the method used.
Co-Creating XR Heritage Narratives: The Tales in Motion Approach
(Springer, 2026) Duguleana, Mihai; Gonçalves, Jorge Manuel Braz; Gonçalves, Fátima; Saraiva, Mónica Patrícia Martins; Moreira, Filipe; Mancho de la Iglesia, Ana; Ibarra Arias, Rocío; Briciu, Victor-Alexandru
This paper presents the methodological framework of the Tales in Motion (TiM) project, an interdisciplinary initiative aimed at preserving and promoting intangible cultural heritage through extended reality (XR). Implemented within the UNITA Alliance and involving partners from Portugal, Romania, and Spain, the project engages local communities in co-creating animated narratives based on regional folklore, myths, and legends. These narratives are developed into immersive augmented-reality experiences, fostering deeper cultural engagement and supporting sustainable cultural tourism. The methodology integrates several phases such as cultural mapping, participatory workshops, collaborative scriptwriting, and iterative prototyping. TiM emphasizes student involvement, cross-sector collaboration, and digital accessibility. The project bridges the gap between heritage and innovation by combining traditional storytelling with state-of-the-art visual technology. This paper outlines the key methodological phases, highlights the challenges encountered and solutions applied, and reflects on the project’s replicability in other cultural contexts. The TiM project benefits local communities, students, educators, cultural institutions, and researchers by preserving cultural heritage through XR, empowering co-creation, and fostering innovation in storytelling, tourism, and digital humanities.
