In this talk, I introduce the recent coronagraph study in S. Korea. Now Korea Astronomy and Space Science Institute  (KASI) is developing a compact coronagraph measuring temperature and velocity of the electron in the corona in collaboration with GSFC / NASA. The compact coronagraph project will be conducted following three steps: 1)total solar eclipse observation to test the method testing(project name: DICE), 2)balloon borne observation to test the instruments including occulter(BITSE), and 3)ISS installation for 2 year operation(CODEX). Now we are preparing to launch BITSE in next year in New Mexico. Here I introduce the DICE and the development of the BITSE including the experimental result of the cone-shaped occulter.
