In order to prove the sedative, anticonvulsive effects of Incenses and to identify the effect of this medicine to cerebral glutamic acid and GABA density in experimental animal. we used Incense which was made of traditional herb medicines. We also examined what kind of material is to be involved in biosynthesis of these elements. In addition we experimented to find out synthesis of active GABA-T. Incenses were inhaled 8 hours a day for 4 weeks to mice. Finally we have following results. On the convulsion induced by pentylenetetrazole(PTZ), Incenses showed significant anticonvulsive effect. Density of glutamic acid in brain was significantly decreased. On the contrary, density of GABA was significantly increased. The Activity of GABA- T in brain was significantly reduced. The quantity of lipid peroxide in the brain was significantly decreased. Activity of xanthine oxidase and aldehyde oxidase were significantly reduced in brain. From the above results, we confirmed that Incenses decreased the density of glutamic acid, increased GABA density and decreased the activity of GABA- T in brain. For the convulsion which was induced by PTZ, Incenses showed significant anticonvulsive effect. With this we can recognize that Incenses had ability to control the quantity of lipid peroxide in brain. In the conclusion, Incenses has significant anticonvulsive effect, so I strongly recommend to prescribe Incenses to treat convulsive disorder like epilepsy.

Shotcrete, rockbolt, and steel rib are installed to support ground after tunnel was excavated. These are important supports for NATM applied tunnels. Recently, lattice girder is increasingly used because it is easily installed. In this study, we developed a new lattice girder by increasing contacting area between spider and rod. To verify the effect of the new lattice girder, the 3-point and 4-point flexural strength tests were carried out for LG-$50{\times}20{\times}30$, LG-$70{\times}20{\times}30$, LG-$95{\times}22{\times}32$. As a result, in case of contacting area, strength of new SGS lattice girder is 17.95% higher than that of original lattice girder. In case of weakness point, strength of new SGS lattice girder is 19.37% higher than that of original lattice girder.
