Generally it is informed that urethane materials are superior to the others in physical characteristics, durability, ground improvement and the influence to environment . But, the existing urethane methods are too expensive to apply. So this study has analyzed the applicability of TAS method which has developed the existing urethane injection mechanism. From the results, Extending the max-infection distance over l0m from 6m which the existing methods could inject to, TAS method has proved to be economical. Also, the TAS method is obtained quickly to ground improvement effect in various tunnel constructions because rise-time was relatively shorter than that of cement-grouting. Therefore, it is expected that TAS method would be applied a lot for water proof and ground improvement etc. owing to its many advantages mentioned the above.

Objectives : Socheongryong-Tang (小靑龍湯, SCRT) has been widely used to treat respiratory disease. In this study, we investigated the protective effects of SCRT on hydrogen peroxide-induced hepatotoxicity. Methods : In the mouse primary liver cells, SCRT was pretreated for 1 h, and 1 mM $H_2O_2$ was treated to mouse primary liver cells. Cell viability was analyzed by using 3- 4,5-Dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT) assay. Also, the activity of AST, ALT and LDH were measured for the evaluation the protective effect of SCRT on $H_2O_2$-induced hepatotoxicity. Intracellular ROS level was analyzed by FACS. Results : SCRT pretreatment decreased $H_2O_2$-induced hepatotoxicity and intracellular ROS production. Pretreatment of SCRT significantly reduced the cytotoxic effect induced by $H_2O_2$, associated with reducing DNA fragmentation and AST, ALT, LDH activities. Conclusions : These results suggest that SCRT has protective effect against $H_2O_2$-induced hepatotoxicity.

In analyzing the effect of the central place improvement projects, this study classifies subject residents into two groups of the residents of the project target regions and those of surrounding villages, and conducts verification. As a result of analysis, Variety of cultural programs is the only factor that positively affects the satisfaction level of the residents of the project target region, and it has been analyzed at the significance level of 10% that a one-unit increase in securing rest areas lowers the satisfaction level of the residents of surrounding villages. This shows that the effect of the central place improvement projects currently promoted is at a low level, and there is also a risk of conflict between the residents in the target region and those in surrounding villages. Although there is no statistical significance, analysis shows that a method to provide the residents in surrounding villages with the project-related information and to guarantee their participation in the project enhances the satisfaction level of the residents of surrounding villages. Therefore, institutional improvements reflecting this need to be made.
