청피반성 혈관염은 만성 재발성 피부혈관병증으로 난치성으로 알려져 있다. 최근 혈전치료제인 acetylsalicylic acid 및 dipyridamole과 혈관확장제인 nifedipine의 병용요법으로 만족할만한 치료효과를 보였다는 보고가 있다. 이에 저자들은 19세 여자에서 임상증상, 병리조직학적 및 직접면역형광검사 소견으로 청피반성 혈관염으로 진단하고 상기 3가지 약제를 병용투여하여 병변의 호전을 보인 1예를 경험하고 문헌고찰과 함께 보고한다. We report a case of livedo vasculitis in a 19-year-old female, who showed multiple, recurrent, O.2-2.Ocm sized, erythematous punched-out ulcers on both ankles and dorsa of feet for 3 years. Histopathologic findings showed granulation tissue, hemorrhage, perivascular inflammatory cell infilteration in upper dermis. Direct immunofluorescent studies showed C3 deposit in dermal vessel wall. Therapy was undertaken with acetylsalicylic acid, dipyridamole, and nifedipine daily, resulting in almost complete resolution of the skin lesion for about 1 month after treatment.

In order to observe the effects of ascorbate on the background current in pyloric circular smooth muscle cells, caffeine of which action was fairly clarified, was used to induce the current systems. To block all of the known currents, various blocking agents were added in the external bathing solution. A part of pyloric circular muscle tissue was excised out, and enzymatic isolation technique was used to obtain Ca^2+ -tolerant single circular muscle cells. The whole cell mode of patch-clamp experiment was conducted. The results were as follows : 1. Ascorbate induced the increase of inward currents in the hyperpolarized potential ranges, and quite a large increase of outward currents in the depolarized ranges. 2. Caffeine also induced similar results, but the magnitude of outward current was smaller than that of assorbate in the depolarized ranges. 3. These phenomena were disappeared by addition of the anion channel blocker. 4. Replacement of external NaCl with NMG·Cl was rarely affected the effects of ascorbate and and caffeine. But the effects of ascorbate and caffeine were almost abolished when sxternal Cl^- was substituted for aspartate. These results suggested that ascorbate affected chloride current which thought as a component of the background currents in the pyloric circular smooth muscle cells.

A reduced structure model of a wind turbine generator is designed and manufactured. Mode data are obtained by modal testing and analytical method. Vibration response is measured and investigated under various speed condition by using a waterfall plot. Possibility of severe resonance is observed and the mechanism is explained by using the mode data. Simplified theoretical model gives the 1st resonance frequency of wind turbine structure model. The theoretical model can be applied in the design stage of the wind turbine structure to avoid the severe resonance problem.

임무열,구경완 永同工科大學校 1995 硏究論叢 Vol.1 No.1

유기금속을 사용한 졸-겔 스핀 코팅법으로 PZT-PNN 박막을 제조하였으며, diethanolamine을 안정화물질로 사용하였다. PT:PZ:PNN의 코팅 용액의 mol%는 각각 #1(50:40:10), #2(50:30:20), #3(45:35:20), #4(40:40:fO), f5(40:50:10), #6(35:45:20) 그리고 #7(30:50:20)으로 제조하였다. 스핀 코팅된 박막의 잔류 유기물을 제거하기 위해 350t에서 예비소결을 하였고, 박막의 결정화를 위해 450℃~ 700℃에서 소결하였다. 백금 기판과 Pt/TiN/Ti/TiN/Si 기판 위에 박막을 성장하였으며, 500℃의 소결에서도 perovskite 상이 출현하였다. 결정성이 가장 양호한 소결온도는 700℃이었다. Sawyer-Tawer 회로를 이용하여 박막위 P-E 이력곡선을 관찰하였다. 박막의 항전계와 잔류분극은 각각 28.8 ㎸/㎝과 18.3 uC/㎠이었다. 유전상수 k는 128 ~ 1120의 값을 나타내었고, 상경계(40:40:20 ㄹmol%)에서 최대값을 보여주었다. 박막의 진성파괴전압은 27.0 ~ 60.0 ㎹/m이었으며, 소결온도가 올라갈수록 파괴 전압은 낮아지는 경향을 나타내었다. PbTiO_3-PbZrO_3-Pb(Ni_1/3Nb_2/3O_3)(PZT-PNN) thin films were been prepared from corresponding metal organics partially stabilized with diethanolamine by the sot-gel spin coating method. The each mol rates of PT:PZ:PNN solutions were #1(50:40:10), #2(50:30:20), #3(45:35:20), #4(40:40:20), #5(40:50:10), #6(35:45:20) and #7(30:50:20) respectively. The spin-coated PZT-PNN films were heat-treated at 350t for decomposition of residual organics, and were heat-treated at temperature between 450t and 750t for crystallization. The substrates, such as Pt and Pt/TiN/Ti/TiN/Si were used for the spin coating of PZT-PNN films. The perovskite phase was observed in the PZT-PNN films which were heat-treated at 500℃ The crystallization of the PZT-PNN films was optimized at 700℃ of sintering temperature. The P-E hysteresis curve was drawn by Sawyer-Tower circuit with PZT-PNN film. The coercive field and the remanent polarization of PBT-PNN film was 28.8 ㎸/㎝ and 18.3 uC/㎠ respectively. Its dielectric constants were shown between 128 and 1120, and become maximum value in MPB. The break down voltages of PZT-PNN films were shown between 27.0 and 60.0 ㎹/m.

Syringoadenoma papilliferum occurs as a solitary lesion appearing usually on the scalp. It's origin is not definitely known, and about one-third of cases are associted with nevus sebaseous. We describe a case of syringoadenoma papillferum associated with nevus sebaseous in a 29 year-old female who had developed bean sized verrucotic nodules on the Rt. temporal area of the scalp since 6 years after removal of nevus sebaceous. Histopathologic findings showed hyperkeratosis, acanthosis and villi that projected into a cystic lumen. And the villi were surrounded by two cell layers.

According to favorable water quality, groundwater is used as subsitutive water resources for surfare water. However, groundwater is contaminated more and more due to industrialization and population increase. This study assesses groundwater vulnerability to contaminants in 12 dongs (administrative districe) of Changwon city using with DRASTIC. DRASTIC was originally applied to the situations that contamination sources are on ground surface, and contaminants flow into groundwater with infiltration of rainfall. In addition to DRASTIC factors, groundwater contamination in urban area is also related with overpumping and with lowering of water level. Correlation coefficient between mumimum values of DRASTIC index and unfitness rate to drinking water quality for 10 dongs is low as 0.40. On the contrary, the correlation coefficient between minimum values of DRASTIC index and groundwater discharge rate and that between minimum values of DRASTIC index and well distribution density are 0.70 and 0.87, respectively. Thus, to evaluate the potential of groundwater contamination in urban areas, it is necessary to consider other factors such as groundwater abstraction rate and well density per unit area with ratings and weights as well as existing six DRASTIC factors.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.
