Background: The purpose of this study was to compare the use of midazolam only with midazolam with fentanyl or propofol in IV sedation. Methods: 24 cases were divided to midazolam group (M group), midazolam + fentanyl group (MF group), midazolam + propofol group (MP group) and midazolam + fentanyl + propofol group (MFP group). In M group, 2 ml midazolam was injected at first, than at 2 minutes interval 1-2 ml injected continuously depending on the level of sedation. In MP, MFP groups, propofol was injected at the speed of 15-20 ml/hr by infusion pump. In this study, the sedation level was evaluated by using OAA/S scale. In each groups, the recovery time was measured until OAA/S scale score level was 5, and pre and postoperative blood pressure change was measured. Each group's data was statistically analyzed using one-way ANOVA. If significant statistical difference were observed, Dunnet test was performed, and control group was M group. Results: Pre and postoperative blood pressure change were not represent significant statistical difference in 4 groups (P value = 0.679 [systolic], P value = 0.206 [diastolic]). But recovery time were represent significant statistical difference (M group: 35.6, MF group: 32.5, MP group: 17.9, MFP group: 19.6 [P value = 0.002]). The result of Dunnet test on recovery time showed significant statistical difference on MF, MFP group when M group was control group. In MFP group, sedation was increased by using supplemental fentanyl, and postoperative pain control was dominant. Conclusion: To achieve the effect of anxiolysis, analgesia, amnesia effectively, and short recovery time, MFP group is mostly recommended.

Herein, we report the manufacture of high-performance, ambipolar organic field-effect transistors (OFETs) and complementary-like electronic circuitry based on a blended, polymeric, semiconducting film. Relatively high and well-balanced electron and hole mobilities were achieved by incorporating a small amount of ionic additives. The equivalent P-channel and N-channel properties of the ambipolar OFETs enabled the manufacture of complementary-like inverter circuits with a near-ideal switching point, high gain, and good noise margins, via a simple blanket spin-coating process with no additional patterning of each active P-type and N-type semiconductor layer.

Objectives : The purpose of this case is to report the improvement after treatment about a patient with cerebral infarction by Sa-Am's Ohaeng-acupuncture and Liuqi-acupuncture. Methods : We treated the patient with acupuncture therapy from 6th September 2004 to 15th November 2004 by reinforcing Dadun(Liv 1) Zusan Li(S36) Quchi(Li 11) and reducing Taibai(Sp 3) on the basis of Etiological Analysis and Differenciation of Endogenous Wind caused by Damp Phlegm and heat. Results .1. Right hemiplegia improved Gr. I to Gr.IV after acupuncture therapy. 2. we interpreted 'reinforcing Dadun(Liv 1) and reducing Taibai(SP 3)'as using Simjeonggyeok in conjunction with Simseunggyeok on the basis of Sa-Am's Ohaeng-acupuncture. 3. we interpreted 'reinforcing Dadun(Liv 1) and reducing Taibai(Sp 3)'as Excreting Dampness in Spleen on the basis of Liuqi-acupuncture. 4. we interpreted 'reinforcing Zusan Li(S 36) and Quchi(Li 11)'as Eliminating Wind-dampness and Menstrual Regulation.
