- - radiative transfer of molecular lines (with Prof. S.S. Hong in SNU)
- > Probing clumpy nature of molecular clouds with three dimensional radiative transfer using Monte Carlo scheme.
- > Investigation of condition under which any molecular line shows self-absorption features.
- > All the asymmetry of self-absorption feature are really associated with infall/outfall kinematics?
- - observational study of dense cores (with Dr. J.S. Kim)
- > I have made an observation of HCN J=1-0 transition toward about 20 class 0 and I young stellar objects.
- > I completed radiative transfer modeling of HCN molecule. It includes allowing line overlapping among hyperfine level/transition and constraining internal strucuture of YSO's.
- > I have plans to make observations towards YSO's in the multi-transitions of CS at a rather uniform beam size of ~40" or better.
- - observational study of high lattitude clouds (as an assistant, with Dr. Y.C. Minh)
- > correlation among CO, 100 micron IR, and HI of MBM7 and MBM40.

- - VLBI
- > KAO/TRAO have a plan to make VLBI experiment with Japanese group and Asia-Pacific Telescope network.

- - holographic surface measurements of high precision large antenna
- > I have applied "narrow band" shearing interferometry to TRAO 14 M telescope for the first time. To my regret, it was found to be only partially successful.

- - participation in Taiwan Sub-Millimeter Array project
- > I am involved in building 2 telescope system in Taiwan which is to be enrolled in SMA interferometer.

- - something like meditation
- > the way of controlling mind via controlled breathing.
- > to feel that the universe and I are connected each other by some energy stream.
