New high technology has been developing rapidly in telecommunication. That wanted to need a display which economical and useful color STN is satisfactory advantages for this condition, and it can control easy better than TFT, organic electroluminescence. But color STN has restriction on real time. Thus, in this paper, we want to control color STN with frequency transform method on converter.

Objective : It was hypothesized that dopamine agonist administration and subthalamic nucleus (STN) lesion in the rat might have a synergistic effect on the neuronal activities of substantia nigra pars reticulata (SNpr) as observed in patients with Parkinson's disease. The effects of SKF38393 (a $D_1$ receptor agonist) and Quinpirole (a $D_2$ receptor agonist) were compared in parkinsonian rat models with 6- hydroxydopamine (6-OHDA) after STN lesion. Methods : SKF38393 and Quinpirole were consecutively injected intrastriatally. SNpr was microrecorded to ascertain the activity of the basal ganglia output structure. The effect of SKF38393 or Quinpirole injection on the firing rate and firing patterns of SNpr was investigated in medial forebrain bundle (MFB) lesioned rats and in MFB+STN lesioned rats. Results : The administration of SKF38393 decreased SNpr neuronal firing rates and the percentage of burst neurons in the MFB lesioned rats, but did not alter them in MFB+STN lesioned rats. The administration of Quinpirole significantly decreased the spontaneous firing rate in the MFB lesioned rats. However, after an additional STN lesion, it increased the percentage of burst neurons. Conclusion : This study demonstrated that dopamine agonists and STN lesion decreased the hyperactive firing rate and the percentage of burst neurons of SNpr neurons in 6-OHDA lesioned rats, respectively. Quinpirole with STN lesion increased a percentage of burst neurons. To clear the exact interactive mechanism of $D_1$ and $D_2$ agonist and the corresponding location, it should be followed a study using a nonselective dopamine agonist and $D_1$, $D_2$ selective antagonist.

In order to elucidate whether capsaicin applied topically acts as a pain-producing subastance or as a tastant, neuronal activities of the chorda tympani nerve(CN), lingual nerve(LN), solitary tract nucleus(STN), and trigeminal nucleus(TGN) were recorded while thermal and taste stimuli, and capsaicin were being applied topically, and algesics intra-arterially to the tongue of cats anesthetized with ${\alpha}-chloralsoe$. In addition, the STN neurons were examined after wheat germ agglutinin-horseradish peroxidase(WGA-HRP) was applied to the CN. The CN fibers responded to taste and thermal stimuli, algesics, and capsaicin. Responses to capsaicin were significantly correlated with those to taste and thermal stimuli. The LN fibers mainly responded to mechanical and thermal stimuli, algesics, and capsaicin. Responses to capsaicin were significantly correlated with those to algesics. The STN neurons responded to taste and thermal stiumli, algesics, and capsaicin. Responses to capsaicin were significantly correlated with those to taste and thermal stiumli in somewhat different fashion from those of the CN fibers. The TGN neurons mainly responded to mechanical stimuli, algesics, and capsaicin. Correlations between responses to capsaicin and any others were not significant. After WGA-HRP was applied to the CN, the STN neurons which receive input from the CN were identified largely in the medio-ventral portion to the solitary tract. These results suggest that capsaicin produce taste as well as pain sensation. Sensory information evoked by capsaicin can be conveyed to the STN, especially medio-ventral portion, via the CN as gustatory information on the one hand, and to the STN or TGN via the LN as noxious information on the other. In addiation, the noxious information may be conveyed to the STN via the CN.

친유기 합성 층상실리케이트(STN)의 함량(1~9 wt%)을 변화하며 폴리아믹산/STN 나노복합재용액을 DMAc 및 THF/MeOH 혼합용매에서 각각 제조하였고, 이를 폴리에스테르 필름에 코팅하여 열적 이미드화 및 화학적 이미드화 반응을 통하여 폴리에스테르/폴리이미드 나노복합필름을 제조하였다. XRD 및 TEM을 이용하여 제조된 폴리에스테르/폴리이미드 나노복합필름의 미세 구조를 조사한 결과 박리형 폴리이미드 나노복합재가 제조되었음을 확인하였다. 표면의 모폴로지 변화는 AFM을 통하여 확인하였으며, 열적 및 기계적 특성은 TGA, DMA와 UTM을 통하여 측정하였다. 또한 STN이 첨가됨에 따라 폴리에스테르/폴리이미드 나노복합필름의 수분투과도는 감소하였고, 화학적 이미드화에 의해 제조된 필름이 열적 이미드화에 의한 필름에 비해 좀더 우수한 수분 차단성을 보였다. 또한 상대적으로 비점이 낮은 THF/MeOH 혼합용매 시스템의 경우가 DMAc를 용매로 사용한 경우보다 더 향상된 수분 차단성을 보였다.

The key point of this design can offer good picture resolution and a high-speed color STN decode. We maximize a combination processing of the color signal. Therefore, there is a color implementation at the natural. The age of the multimedia comes, so the color is considered important and wide. To be necessary a color implementation have become the importance which picture resolution is clean and low price of the liquid display TFT occupied greater part of the liquid display. But TFT could not consist low price realization. This research is a color implementation of STN at low price, design good picture resolution decode for optimum an limit of upside with frequency range maximizing and can reply in the high-speed by multidivision method. As a result, we design optimum of the STN decode.

In this paper the driving-condition-dependent optical transmission characteristics of an STN LCD are studied. The optical transmission properties are measured for the applied voltage waveform is varied. Also, the optimum ranges of the M signal frequency and the frame frequency are investigated. An LCD is modeled by the equivalent circuit to study the effect of the parameter variation on the frequency response.

본 논문에서는 LCD의 설계, 해석, 평가를 위한 시뮬레이션용 프로그램을 개발하였다. 본 프로그램은 액정 배향, 광투과율, 휘도, CONTRAST, 응답시간, 색좌표, 시야 각 특성등을 계산한다. 경사 입사광에 관한 해석은 확장된 2${\times}$2 행렬법으로 자체 개발하여 계산한다. 또한, 이 프로그램은 LCD 구조물의 최적 설치조건을 계산하는 기능도 갖는다. 이에 의하여 애정 표준화 작업관련 데이타 비교, B/W STN, TFT 등의 측정결과와 시뮬레이션 결과의 비교를 하였다.
