Objectives : The conventional direct and indirect moxibustion therapies for prostate treatment could not been applied to the acupuncture point of $CV_1$(Conception Vessel Meridian 1, 會陰) because of its boring body region. The position of $CV_1$(會陰) is the back side of hard part between the anus and the genital organ. The conventional moxibustion methods have many troubles in operating to the acupuncture point of $CV_1$(會陰). In order to get rid of these problems, we have suggested the special heat generating terminal especially for prostate. The features of the special heat generating terminal for prostate are the low temperature infrared heater and the adhesive moxa-pad. These features are no burnt, no fiery and especially suitable for the point of $CV_1$(會陰). Methods: The heat generating terminal which is a part of the moxa-extract moxibustion cauterizer is composed of a PTC(Positive Temperature Coefficients) ceramic heater and the adhesive moxa-pad We had got the experimental demonstrations by the stimulating the acupuncture points which are $CV_1$(會陰), $BL_{28}$(Bladder Meridian 28, 膀胱兪), and $CV_3$(Conception Vessel Meridian 3, 中極) with the special heat generating terminal for the prostatitis and the benign prosthetic hypertrophy. And the stimulation level was 43$^{\circ}C$ infrared heat for one hour. The type of thermography is IRIS-5000. Results : With one subject suffering the prostatitis and another subject suffering the benign prosthetic hypertrophy, we cauterized the acupuncture points $CV_1$(會陰), $BL_{28}$(膀胱兪) and $CV_3$(中極) with the special heat generating terminal for prostate. We measured the temperature variations by the thermography before and after stimulations. Finally we estimated the tendency of temperature decreasing in the region of post-stroke urinary symptoms and the improvement of nocturnal enuresis after the stimulations. Conclusions : We suggest that the special heat generating terminal of moxa-extract moxibustion cauterizer proposed herein is effective for the treatment of prostate by NIH-CPSI and IPSS.

$BaTiO_3$는 perovskite 구조를 가지는 대표적인 강유전체 재료로서 MLCC(Multi Layer Ceramic Capacitor), PTC thermistor등에 널리 사용되어지고 있다. 최근 고용량 MLCC 의 상업화와 함께 나노크기를 갖는 tetragonal phase의 $BaTiO_3$ 입자를 합성하기 위한 다양한 제조방법이 제시되고 있다. 또한 유전 특성과 온도특성 및 신뢰성을 향상시키기 위해 많은 첨가제들이 연구되어지고 있다. 따라서 이 번 연구에서는 선행 연구를 통해 얻어진 high energy mill을 이용한 고상반응법으로 제조된 $BaTiO_3$를 사용하였으며, 제조된 $BaTiO_3$ 분말에 glass frit를 첨가하여 소결온도 및 유전특성의 변화를 관찰하였다. 제조된 $BaTiO_3$ 분말은 200nm이하의 구형화와 균일한 입자크기를 보였으며, 선행연구를 통해 최적화된 glass frit의 양인 2.53wt%를 첨가하였고 1170, 1200, $1230^{\circ}C$에서 소결하여 소결온도에 따른 변화를 관찰하였다. 실험방법으로는 원료를 혼합하기 위하여 24시간 ball-mill을 이용하여 혼합하였으며, $\Phi15$로 성형하여 소결을 진행하였다. 실험진행 결과 모든 시편에서의 비유전율은 glass frit가 첨가되지 않은 조성보다 높게 나타났으며, $1200^{\circ}C$에서 소결한 시편의 비유전율($\varepsilon_r$)은 2300으로 glass frit가 첨가되지 않은 조성과 비교하여 21% 증가하여 최대치를 나타냈다. 또한 소결온도 $1200^{\circ}C$ 이상에서의 모든 시편에서는 95% 이상의 상대밀도를 나타내어, glass frit가 소결조제로써의 역할을 하는 것으로 나타났다. 따라서 본 연구를 통해 glass frit첨가로 인한 소결온도 감소 및 유전특성이 증가하는 것을 확인 하였다.

$BaTiO_3$는 perovskite 구조를 가지는 대표적인 강유전체 재료로서 MLCC (Multi Layer Ceramic Capacitor), PTC thermistor 등에 널리 사용되어지고 있으며, 그 특성을 향상시키기 위하여 많은 연구가 진행되고 있다. 현제 $BaTiO_3$ 분말 제조의 대표적인 합성법으로는 하소와 분쇄공정이 없는 수열합성법이 대표적이나, 나노 사이즈로 제작시 $BaTiO_3$는 마이크로 크기와 달리 입방정상으로 우세한 상태로 존재한다. 이는 제조과정 중의 hydroxyl defect의 영향과 나노 분말의 표면에너지 증가 때문이라고 보고된다. 따라서 본 연구는 이러한 문제점을 해결하기 위해 일반적인 세라믹 제조 방법인 고상반응법을 이용한 나노 사이즈의 $BaTiO_3$ 제조를 위한 최적의 공정 조건을 확립하기 위하여 본 연구를 진행하였다. 조성은 $BaTiO_3$와 반응온도를 낮추기 위한 anatase의 $TiO_2$를 사용하였고, $BaCO_3/TiO_2$ 의 조성비 (1. 1.01, 1.02, 1.03)를 제어하여 혼합한 후, 24h ball-mill 하여 하소 온도 ($860^{\circ}C{\sim}1000^{\circ}C$) 변화에 따른 입자 사이즈와 입도 분포를 측정하였다. 제조된 $BaTiO_3$분말의 결정 구조 분석을 위하여 XRD (X-ray diffraction) 분석을 수행 하였는데, 분석 결과로부터 제조된 분말들이 정방정 (tetragonal)의 perovskite구조를 갖고 있음을 확인하였다. 또한 분말의 미세구조 확인을 위하여 SEM (scanning electron microscope) 관찰을 수행하였는데, 나노 사이즈의 구형 분말을 얻을 수 있음을 확인할 수 있었다.

Objectives : We implemented the Moxa-Extract Moxibustion Method in order to improve the conventional moxibustion therapy. This method is aimed to eliminate burning wounds and smoke, which are the defects of conventional moxibustion therapy. And we performed to verify the efficiency by comparing the Moxa-Extract Moxibustion Method with the conventional Indirect Moxibustion Method. We measured the body heat and the lasting time of blood circulation improveent using thermography. We implemented the Moxa-Extract Moxibustion Method in order to improve the conventional moxibustion therapy. This method is aimed to eliminate burning wounds and smoke, which are the defects of conventional moxibustion therapy. And we performed to verify the efficiency by comparing the Moxa-Extract Moxibustion Method with the conventional Indirect Moxibustion Method. We measured the body heat and the lasting time of blood circulation improvement using thermography. Methods : The moxibustion therapy has two kinds of effects: The formers are pharmacological effects of the Moxa's vasodilators and antioxidants. The latters are thermal effects which cause improvement of the blood circulation. To remove the demerits without omission of above therapeutic effects, we extracted the vasodilators and antioxidant compounds from the Moxa-CH2Cl2 fraction Moxa-EtOA and composed the moxibustion kit with (Ba0.8 Sr0.2)0.996 Y0.004 TiO2 + 0.5WT SiO2% positive Temperature Coefficients Thermistor. The experimental demonstrations have been made by the stimulating the spot which is CV4(Kwan-Won), CV8(Shin-Guel), CV12(Jung-Wan) acupuncture points of the conception vessel meridian(CV). And stimulating time was one hour. We divided the subjects into 5 groups such as no stimulation group, conventional Indirect Moxibustion group, only Moxa-Extract stimulation group, only heat stimulation group, and Moxa-Extract Moxibustion group. In the different cases, we have measured the body heat in pre-stimulation, just after stimulation, 2 hours after, and 4 hours after. Results : he body heats of the group who were stimulated by the Moxa-Extract Moxibustion method were increased by over the $2^{\circ}C$. And the body heats of the group who were stimulated by the Indirect Moxibustion Method were increased by average the $1^{\circ}C$. We have evaluated that the Moxa-Extract Moxibustion Method is improvement on the Indirect Moxibustion Method by the increasing rate is 200% and increasing time is 150% with the body heat of the abdominal region. Conclusion : We have implemented the Moxa-Extract Moxibustion Method and evaluated the efficiency of the Moxa-Extract Moxibustion Method comparing with the Indirect Moxibustion Method.

The latters are thermal effects which cause improvement of the blood circulation. To remove the demerits without omission of above therapeutic effects, we extracted the vasodilators and antioxidant compounds from the Moxa-$CH_2Cl_2$ fraction Moxa-EtOAc and composed the moxibustion kit with $(Ba_{0.8}\;Sr_{0.2})_{0.996}\;Y_{0.004}\;TiO_2+0.5_{WT}\;SiO_2%$ Positive Temperature Coefficients Thermistor.
