Recently, both volumes and weights of antennas are increasing because of advancement of satellite missions. Research studies on mesh deployable antennas that can be highly stowable and lightweight are also increasing. When a deployable mesh antenna is subjected to repeated deployment tests on the ground, vibration of launch environments can cause slip between the antenna structure and the mesh fabric, resulting in failure to maintain the surface curvature of the antenna and Openning Per Inch (OPI). Such failure is the main cause of RF performance and mission capability degradation. Thus, studying a fastening technique to prevent slip between the antenna structure and mesh fabric is essential. This study proposed a Clamping fastening technique using rivets between the antenna structure and the mesh fabric. To evaluate the fastening efficiency of the Clamping fastening technique, tensile tests were conducted according to antenna structure type and rivet increment. Results were analyzed and fastening efficiency of the proposed clamping fastening technique was verified.

2.5D Mapping system that embody in this paper can make new design by doing draping to live various texture and model picture image of fashion clothes by pattern, and can confirm clothes work to simulation without producing direction sample or product directly. Also, the system can support function that can forecast fabric design and state of end article exactly, and the system can bring competitive power elevation of fashion industry and cost-cutting effect by doing draping using database of fabric and model picture image. 2.5D Mapping system composed and embodied by mesh warp algorithm module, light and shade extraction and application module, mapping path extraction module, mesh creation and transformation module, and 2.5D mapping module for more natural draping. Future work plans to study 3D fashion design system that graft together 3D clothes technology and 3D human body embodiment technology to do based on embodiment technology of 2.5D mapping system and overcomes expression limit of 2.5D mapping technology.

The recent trend in younger generations of wearing traditional costumes or incorporating fusion hanbok into daily wear necessitates the development of modern hair accessories to complement hanbok. The purpose of this study is to develop practical and modern hair accessory designs inspired by royal women's hair ornaments that complement hanbok, and therefore expand the scope of fashion content development utilizing hanbok culture as well as meeting the demand for various experiences of traditional culture. This research studied the literature on traditional hairstyles and accessories of Queen Yeong and constructed models of these accessories for the purpose of empirical research. The production process first required creating a basic foundation of nylon mesh reflecting the silhouette of a traditional hairstyle, and then grafting a digital textile printed fabric using majestic and extravagant royal relics on top, thus employing the trompe l'oeil technique to ultimately give the impression of wearing traditional jewelry. As a result, a total of six hair accessory designs were completed, produced with hairbands, hair pins, and hair ties. In addition, the accessories are designed to be easily worn regardless of the wearer's hair style, and the stiff yet flexible nylon mesh effectively expresses the shape of a voluminous hairstyle and creates an optical illusion, blending into the hair. These research results present a unique aesthetic and cultural experience to the greater public seeking both daily entertainment and value from rarity.
