Currently, the current status of mobile apps in traditional markets is still passive in digitalization, and services provided using mobile apps are limited. This study aims to propose a cloud platform-based mobile platform that can overcome digital transformation, strengthen the competitiveness of traditional markets, and revitalize the local economy by more consumers visiting traditional markets. This study identified the current situation and problems of the market due to its characteristics, and analyzed the impact and opportunities of cloud and mobile technology on the characteristic market. It also implemented a cloud-based smart traditional market mobile platform prototype. The platform combines the advantages of traditional markets with digital benefits to deliver value to all users, social, industrial, I hope it will be of great help on the social side.

Immersive content provides a differentiated and immersive experience from existing content. It is a type of content that stimulates various senses, such as vision, hearing, touch, smell, and taste, to allow users to experience the world as if it were real. Among them, holograms are a technology that creates three-dimensional images using light. Unlike traditional 2D images, holograms can provide a realistic experience. The three-dimensionality and depth of holograms make users feel a strong sense of space and presence, making them a promising next-generation content for expressing virtual worlds. This study aimed to analyze the suitability of hologram technology for immersive content and the correlation between storytelling in immersive content in this trend. To this end, we produced a holographic immersive content of Tchaikovsky's "Swan Lake," which has a narrative structure of rising action, climax, and falling action. In the production process, we used floating solar panels as a power source, considering the environmental aspect. We showed the produced immersive content to related experts and collected their opinions through semi-structured interviews. As a result of the analysis, we confirmed that holograms are an effective technology for enhancing the immersion of immersive content. We also confirmed that storytelling plays an important role in enhancing the immersion of immersive content.

Recently, as the demand for a non-contact liquid crystal alignment method capable of improving viewing angle characteristics has spread throughout the industry, various non-contact liquid crystal alignment methods, including conventional UV light alignment, are being actively studied. In the case of UV light alignment, it is currently applied to mass production in many fields and shows relatively excellent initial characteristics, but there is a problem of display quality deterioration over time. In this study, among these non-contact liquid crystal alignment methods, the liquid crystal is oriented by quantitatively irradiating an ion beam onto the SiOF inorganic film, which has excellent initial characteristics and does not cause deterioration in quality over time., the electro-optical properties were evaluated by manufacturing a commercial-level IPS (In-Plane Switching) liquid crystal cell. In particular, in the case of such inorganic film orientation, it is common to have many problems with orientation stability, but the evaluation cell manufactured by the method proposed in this study is capable of maintaining a uniform orientation without losing orientation even after heat treatment at a high temperature of 200°C. could be observed.

In this study, we studied the method of using general architectural glass instead of using the existing acrylic material for high luminance flat lighting. The flat panel lighting used the side illumination method to increase the ease of installation and aesthetic satisfaction. In general, glass has an amorphous structure with a lower angle of refraction than acrylic, so it is not suitable for use in flat panel lighting as a light guide, but in this study, the role of light distribution characteristics and diffusion patterns in the case of using such a glass light guide. Quantitative simulations were conducted to confirm new possibilities. In the simulation, the backlight estimation method was used, and about 10,000,000 rays were placed within a unit area in order to obtain a result similar to the real thing. As a result of the simulation, the geometry of the diffusion pattern could be specified, and the value of the geometry could be quantified using the ratio of the diameter and height of the pattern. As a result of the calculation, it was found that the maximum amount of light was generated around 75 degrees by quantitatively calculating the ratio and the outgoing light angle at which the maximum value of the outgoing light occurred between 05 and 1.0. As a result of these studies, it was confirmed that it is possible to use ordinary glass at the same time as a transparent window and light-emitting lighting at night.

For research and development of Silicon Carbide (SiC) mirrors, the Korea Astronomy and Space Science Institute (KASI) and National Optical Astronomy Observatory (NOAO) have agreed to cooperate and share on polishing and measuring facilities, experience and human resources for two years (2014-2015). The main goals of the SiC mirror polishing are to achieve optical surface figures of less than 20 nm rms and optical surface roughness of less than 2 nm rms. In addition, Green Optics Co., Ltd (GO) has been interested in the SiC polishing and joined the partnership with KASI. KASI will be involved in the development of the SiC polishing and the optical surface measurement using three dierent kinds of SiC materials and manufacturing processes (POCOTM, CoorsTekTM and SSGTM corporations) provided by NOAO. GO will polish the SiC substrate within requirements. Additionally, the requirements of the optical surface imperfections are given as: less than 40 um scratch and 500 um dig. In this paper, we introduce the international collaboration and interim results for SiC mirror polishing and development.

A prototype of the GMT FSM has been developed to acquire and to enhance the key technology – mirror fabrication and tiptilt actuation. The ellipsoidal off-axis mirror has been designed, analyzed, and fabricated from light-weighting to grinding, polishing, and figuring of the mirror surface. The mirror was tested by using an interferometer together with CGHs, which revealed the surface error of 13.7 nm rms in the diameter of 1030 mm. The SCOTS test was employed to independently validate the test results. It measured the surface error to be 17.4 nm rms in the diameter of 1010 mm. Both tests show the optical surface of the FSMP mirror within the required value of 20 nm rms surface error.
