  • The endometrium undergoes a cyclic growth and tissue remodeling as changes of epithelial cells, and plasminogen activators (PAs) are related to endometrium tissue remodeling. This study was to evulate expression of urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA) in porcine uterine epithelial cells. In results, the uPA and tPA were expressed in uterine tissue, epithelium and secretory glands in porcine endometrial cell. In addition, the uPA and tPA were expressed in cultured epithelial cells, and it were mainly expressed in cytoplasm. In porcine uterine tissue and epithelial cells, uPA activity was higher than activity in tPA. In PAs mRNA expression levels, uPA mRNA level was significantly higher than tPA mRNA level (P<0.05). The fluorescence intensity of uPA protein was also higher than fluorescence intensity of tPA protein, and uPA protein expression was significantly higher than in tPA protein expression (P<0.05). Therefore, we suggest that a physiological function in porcine uterine epithelial cells should be more influenced by uPA than in tPA during pre-ovulatory phase.

  • Fabrication technique of $(Th,U)O_2$ pellets has been investigated. Powder mixtures of $ThO_2\;and\;UO_2$ were milled in two different ways-dry and wet milling. Milled powder was compacted and sintered to $(Th,U)O_2$ pellets. The wet-milled powder leads to a $(Th,U)O_2$ pellet having a high sintered density and uniform distribution of U and Th, compared to the dry-milled powder. The sintered density of a $(Th,U)O_2$ pellet tends to decrease by increasing the content of $ThO_2$. The thermal conductivity of $ThO_2\;and\;(Th,U)O_2$ pellets was measured by the laser flash method. The thermal conductivity of the $ThO_2$ pellet is higher than that of the $UO_2$ pellet, and the thermal conductivities of $(Th,U)O_2$ pellets containing $65wt\%\;and\;35wt\%\;ThO_2$ pellets are lower than that of the $UO_2$ pellet.

  • In order to investigate experimentally the effects of $So{\breve{u}}m$-In Bojungikit'ang and Dong-Won Bojungikit'ang on Yang-Insufficient syndrome(陽虛證) induced by Hydrocortisone acetate(HA) in experimental animals(Mice and Rats), the author experimented with various activities. Body temperature(BT), Body weight(BW), Exercise time, Cyclic-AMP, the Ra's Hair condition was measured. The results obtained are as follows : 1. In body temperature, the Dong-Won Bojungiki'ang treated group was increased significantly and the $So{\breve{u}}m$-In Bojungikit'ang treated group showed no significance. 2. In body weight, the $So{\breve{u}}m$-In Bojungikit'ang treated group had increased significantly and the Dong-Won Bojungikit'ang treated group showed no significance and there was a significant difference between the $So{\breve{u}}m$-In Bojungikit'ang and the Dong-Won Bojungikit'ang. 3. In exercise time. the $So{\breve{u}}m$-In Bojungikit'ang and the Dong-Won Bojungikit'ang treated groups were significantly increased. 4. In cyclic AMP, both experimental groups showed increasing tendancy, but showed no significance. 5. In the Rat' s hair condition. the $So{\breve{u}}m$-In Bojungikit'ang showed significance. 6. There was no significant difference between the $So{\breve{u}}m$-In Bojungikit'ang and the Dong-Won Bojungikitang except the body weight. from the above findings. (1) it has been demonstrated thet the $So{\breve{u}}m$-In Bojungikit'ang and Dong-Won Bojungikit'ang groups seem to produce the effecticeness on the recovery from depression of metabolism induced by Bydrocortisone acetate. (2) In body temperature response the Dong-Won Bojungikit'ang had effectiveness during recovery. (3) In body weight response the $So{\breve{u}}m$-In Bojungikit'ang had the effecticeness during recovery. (4) In exercise time. Both experimental group had the effectiveness during recovery. (5) In cyclic AMP response. both experimental group had no effectiveness during recovery. (6) In the Rat's hair condition response the $So{\breve{u}}m$-In Bojungikit'ang group had the effectiveness during recovery. Therefore in is suggested theat the $So{\breve{u}}m$-In Bojungikit'ang and Dong-Won Bojungikit'ang groups had effecticeness during recovery from Yang-Insufficient syndrome more of less.

  • 본 연구에서는 은 나노와이어를 도포 한 후 온풍을 이용하여 용매를 건조시키는 공정을 진행 후 광학적, 전기적 특성을 평가 하였다. 은 나노와이어를 스포이드로 글라스 위에 도포한 후 약 $120^{\circ}C$의 온도와 17m/s의 풍속을 가진 바람을 30초간 기판에 조사하였으며, 같은 방법으로 1 ~ 3회 반복하여 기판의 전기적, 광학적 특성을 조사 하였다. 그 결과, 550nm에서 3회 반복 도포 시 87.8%의 투과율과 18ohm/sq의 면저항을 가지는 투명 박막을 얻을 수 있었다.

  • 고사양을 요구하는 차세대 디스플레이용 소자 중 하나로 산화물 TFT(thin-film transistor)가 주목받고 있으며, 기존의 a-Si TFT보다 월등한 성능을 보인다. 소자의 특성을 개선시키기 위해 back channel 표면에 플라즈마 처리를 하였다. 플라즈마처리시 산소의 비중이 늘어날수록 산화물 TFT의 특성을 개선하는데 도움을 주는 것을 확인하였다.
