진단형 가속도센서에 사용될 수 있는 Pb(Zr,Ti)O_(3)계의 압전세라믹스를 제조하였다. 연구된 조성중 La^(+3),Nb^(+5)가 첨가된 조성이 가장 우수한 d_(15),K_(15)값을 갖고 있었으며 La^(+3)첨가에 의하여 상경계는 능면체정계로 이동하였다. Piezoelectric ceramics of Pb(Zr,Ti)O_(3) system were fabricated and used for shear type accelerometer. Among compositions studied , La^(+3) and Nb^(+5) doped composition showed the highest d_(15), and K_(15) and the morphotropic phase boundary (M.P.B) was shifted toward rhombohedral site.

Gene delivery is one of the keen interests in animal industry as well as research on gene functions. Some of the in vivo gene delivery 'techniques have been successively used in various tissues for the gene therapy and transgenesis. Despite intensive efforts, it still remains to overcome problems of limited loral and regional administration and low transgene expression. To improve the efficiency of gene delivery, a new procedure was tested. We injected exogenous DNA containing LacZ into the female or male gonads and then pulsed electric field. Electroporated gonads showed positive X-gal staining in many seminiferous tubules of the porcine fetal gonads. Exogenously introduced LacZ genes were also expressed in female porcine gonad. In addition, we demonstrated efficient gene delivery in gonad of adult mouse. Furthermore, we succeed to generate genetically modified germline cells showing GFP and positive X-gal signals. The results suggest that the newly developed gene delivery is an effcetive way of invivo transfection in mammals. The developed gene delivery procedure should be useful in producing transgenic animals when combined with primary cell culture and nuclear transplantation.
