The Korea Superconducting Tokamak Advanced Research (KSTAR) project is the major effort of the national fusion programme of the Republic of Korea. Its aim is to develop a steady state capable advanced superconducting tokamak to establish a scientific and technological basis for an attractive fusion reactor. The major parameters of the tokamak are: major radius 1.8 m, minor radius 0.5 m, toroidal field 3.5 T and plasma current 2 MA, with a strongly shaped plasma cross-section and double null divertor. The initial pulse length provided by the poloidal magnet system is 20 s, but the pulse length can be increased to 300 s through non-inductive current drive. The plasma heating and current drive system consists of neutral beams, ion cyclotron waves, lower hybrid waves and electron cyclotron waves for flexible profile control in advanced tokamak operating modes. A comprehensive set of diagnostics is planned for plasma control, performance evaluation and physics understanding. The project has completed its conceptual design and moved to the engineering design and construction phase. The target date for the first plasma is 2002.

Due to the recent COVID-19 pandemic, many performances have been conducted using computer-medicated communication technologies. Many performances took the form of online concerts that utilize live streaming technologies. Some artists held virtual avatar concerts on virtual reality platforms to provide a higher level of immersion and various scenes and effects. Conventional virtual avatar concerts typically require performers to wear motion capture equipment to track their movements on the fly, limiting performers' choice of outfits and making it challenging to simultaneously perform virtual and online concerts in a single performance. In this study, to overcome these limitations, we propose a simulcast system design for live streaming and virtual avatar concerts. The proposed system allows performers to wear desired costumes by tracking performers' movements using RGB-D sensors. We implemented the prototype system proposed in this study using 3 Microsoft Azure Kinects and 1 iPhone and examined the system's performance. We validated the prototype system by conducting a test performance with a famous Korean singer, Kyung-rok Kim, of the group V.O.S. Finally, given the limitations of this study, we suggested the future research directions of developing a virtual avatar concert system that allows for greater flexibility and creativity in performers' outfits and movements. We expect that the proposed system will enhance the efficiency of concert production by enabling the simultaneous broadcasting of a single concert across multiple platforms. This, in turn, will help attract a larger audience, increasing the concert's exposure and reach.
