Polymer gel implant for soft tissue augment is demanded biological safety properties. This study is designed process and equipment producing for obtain micro bead using the hyaluronic acid water solution. This equipment is composed of cooling pipe, air pump, dispenser and process is consecutive/simple for preservation from environmental contamination. Besides, without difficulty remove the residual agent after crosslink. We evaluate to in vitro cytotoxicity test for verification of hyaluronic acid gel obtained by this equipment and process. This product is "non cytotoxcity" from the result of evaluation cytotoxcity test.

A survey project of TRAO with the fifteen beam array receiver system is presented. A multibeam array receiver system has been purchased from FCRAO, and is being installed on TRAO 14m telescope. The target region of the survey is from ι=120° ~137°, b=-1°~+1°, and velocity resolution would be 1 km/sec after smoothing from the original resolution of 0.64km s-1in the transition of J = 1-0 of 13CO The survey region is a part of the 12CO Outer Galaxy Survey(OGS), and would be an extension of the Bell Laboratories 13CO Galactic Plane Survey. By combining with the existing 12CO database of the Outer Galaxy Survey, we will derive physical properties of identified molecular clouds and will conduct and statistical analysis of the Outer Galalxy molecular clouds. Reduction process and analysis methods will be introduced.
