  • During helicopter rotor system development process, whirl tower test is conducted basically. For conducting whirl tower test during bearingless hub development process, design new blade or using existing blade with repair or remodeling. Because simple shape and efficient aerodynamic characteristic, BO-105 blade is used for hub system development widely. Originally BO-105 Blade is used for hingeless hub, so flap stiffness and lag stiffness on blade root area is relatively low. So appling BO-105 blade to bearingless hub whirl tower test, root area have to be reinforce. In this paper, suggest reinforcement method of BO-105 blade root area.

  • The low temperature sintering of dolomite type borates, $CaZr(BO_3)_2$[CZB] ceramics and their microwave dielectric properties were investigated The sintering temperature of CZB ceramics could be reduced from $1150^{\circ}C$ to $925^{\circ}C$ by the addition of sintering additive. $CaZrO_3$, $ZrO_2$ and $CaB_2O_4$ second phases were found in the CZB ceramics. The syntheses, sintering properties, microstructures, and dielectricnproperties of dolomite-type borates were examined by XRD, thermal analysis, electron microscopy, network analyzer, and the results are discussed intensively. The compatibility with silver electrode was also explored.

  • During 9 months the clinical study on the 45 cases constipation patients caused by C.V.A, who were treated with Bo-Riu Enema, was done in the Department of Oriental Internal Medicine II, Oriental Medicine Hospital, Taejon University. The result of this study is compared with glycerin-enema treated group. The results were as follows ; 1. The incidence rate of constipation caused by C.V.A is higher in old aged group. 2. The incidence rate of constipation caused by C.V.A is higher in Tae-Um-In(太陰人). 3. The improvement rate of constipation caused by C.V.A is higher in Bo-Riu Enema treated group than in glycerin-enema. 4. The admission period is shorter in Bo-Riu Enema treated group than in glycerin-enema. 5. In case of paralytic ileus, the improvement rate of constipation caused by C.V.A is higher in Bo-Riu Enema treated group than in glycerin-enema.
