Intangible cultural heritage is a people-centered living cultural heritage. Preservation, promotion, and talent cultivation are important aspects of intangible cultural heritage protection and also crucial guarantees for sustainable development. However, traditional video recordings lack three-dimensional spatial information, and the high cost of digital scanning and reconstruction still leaves no convenient, efficient, accurate, realistic, and low-cost solution for the preservation and dissemination of intangible cultural heritage projects. Here we introduce the binocular 180-degree panoramic display method, through which a platform for recording, showcasing, disseminating, and teaching intangible cultural heritage projects in the Sanlin Old Street of Shanghai was implemented. The platform requires only VR filming without the need for 3D modeling technology. The participants can freely select intangible cultural heritage projects on the map and immerse themselves in watching the Sanlin “Three Excellence” porcelain carving, local cuisine, and embroidery. They can also enjoy the dragon dance, experience the textile craftsmanship of Sanlin’s “Three Specialties”, and even observe the production process and details of the works from the perspective of the inheritor in the first person. The results show that compared to traditional video recordings and digital scanning reconstruction, the binocular 180-degree panoramic display provides a one-to-one, face-to-face, and low-cost solution for the preservation and dissemination of projects. It allows students to increase their knowledge of intangible cultural heritage and enhance their interest in inheritance. Full article

Traditional dance is one of the key elements of Intangible Culture Heritage (ICH). Many scientific papers concern analysis of dance sequences, classification and recognition of movements, making ICH data public, creating and visualising 3D models or software solutions for learning folklore dances. These works make it possible to preserve this disappearing art. The aim of this article is to propose a methodology for scanning folklore dances. The methodology was developed on the basis of capturing 3D data via an optical motion capture system with a full body Plug-in Gait model that allows for kinematic and kinetic analysis of motion sequences. An additional element of this research was the development of a hand model with which it is possible to precisely analyse the fingers, which play a significant role in many dances. The present methodology was verified on the basis of the Lazgi dance, included in the UNESCO ICH list. The obtained results of movement biomechanics for the dance sequence and the angles of the fingers indicate that it is universal and can be applied to dances that involve the upper and lower body parts, including hand movements.

Background and objective: In DanceSport, athletes train for many years to develop a very specific posture. Presently there are few data as to whether these adaptations are habitual or cause permanent anatomical changes to the spine. The aim of the current study was to evaluate lumbar lordosis and thoracic kyphosis of the international level DanceSport dancers using track and field athletes as controls.
Materials and methods: Thirty competitive DanceSport couples (15 men aged 23.4 ± 6.6 years; 15 women aged 22.5 ± 6.4 years) and 29 track and field athletes (16 mean aged 27 ± 4.4 years and 13 women aged 22 ± 4.1 years) volunteered. Twelve couples were Standard, 7 Latin American and 11 were Ten Dance couples. Thoracic kyphosis and lumbar lordosis angle were assessed in lateral view using a Vertebral Fracture Assessment scan.
Results: DanceSport athletes had smaller S-shaped vertebral curvatures compared to track and field athletes. Male (5.7 ± 4.78) and female dancers (8.7 ± 5.98) had significantly smaller lumbar lordosis angle compared to their track and field counterparts (22.3 ± 9.98 for men; 20.3 ± 5.98 for women).Femaledancers(25.3 ± 8.08)alsodemonstratedsignificantly smallerthoracickyphosis angle than female track and field (32.1 ± 8.98) participants. It was further revealed that female Latin American dancers had significantly smaller lumbar lordosis values (3.7 ± 3.18) compared with female Standard (10.7 ± 6.18) and Ten Dance dancers (9.7 ± 5.58).
Conclusions: The results of the present study suggest that smaller S-shaped vertebral curvatures of DanceSport athletes compared with track and field athletes are permanent changes rather than habitual. Full article
