The current experiment was carried out to investigate the analgesic effects of several herbal drugs in acetic acid - induced pain model. In a single drug group : after administration of herbal drugs(1g/kg or 3g/kg) orally for 30 minutes, 1% acetic acid $(250{\mu}l)$ was administered into abdominal cavity of mouse. And then the number of times of writhing response was measured for 30 minutes. In a combination drug group : after administration of herbal drugs (1g/kg and it's compound 2g/kg) orally for 30 minutes, 1% acetic acid $(250{\mu}l)$ was administered into abdominal cavity of mouse. And then the number of times of writhing response was measured for 30 minutes. The results were summarized as follows; 1. Water extracts of Akebiae caulis(木通) and Stephaniae tetrandrae radix(防己) decreased significantly the number of writhing response. 2. Methanol extracts of Achyranthis bidentatae radix(牛膝), Carthami flos(紅花), Akebiae caaulis(木通), Stephaniae tetrandrae radix(防己), Myrrha(沒藥), Corydalidis tuber(玄胡索) and Persicae semen(桃仁) decreased significantly the number of writhing response. 3. Water extracts of Achyranthis bidentatae radix(牛膝) plus Akebiae caulis(木通), Achyranthis bidentatae radix(牛膝) plus Stephaniae tetrandrae radix(防己) and Achyranthis bidentatae radix(牛膝) plus Ledebouriellae radix(防風) decreased the number of writhing response significantly. 4. Methanol extracts of Achyranthis bidentatae radix(牛膝) plus Myrrha(沒藥), Achyranthis bidentatae radix(牛膝) plus Stephaniae tetrandrae radlx(防己) and Achyranthis bidentatae radix(牛膝) plus Ledebouriellae radix(防風) decreased the number of writhing response significantly.

The shape of a iron bed supporting a permanent magnet in a large-sized motor is a important factor for determining the coupling strength with the yoke. In a large-sized motor, there is a difference in electromagnetic force with the yoke depending on the shape of the iron bed. In this paper, we show the differences and problems by calculating the electromagnetic force between the double bed and the single bed through the virtual air gap, and show that the single bed is superior in terms of the binding force. It is also shown that the binding force between the bed and the yoke is improved by carving the groove shape under the bed.

PDP는 벽걸이형 대형 평판 디스플레이로서 최근 시각적 극대화에 도운이 되는 대형화의 가능성과 자연스러운 색감 표현력 등의 장점 때문에 주목받고 있다. 하지만 저계조 표현, 의사 윤곽 문제등의 화질 저하 문제로 우위에 있지 못하고 다fms 디스플레이 장치들과 치열한 경쟁을 하고 있어 더욱 많은 화질 연구가 필요하다. 본 논문은 42" PDP의 화질 개선 연구를 위한 Verilog HDL을 이용한 소프트웨어 테스트-베드 구현과 FPGA를 이용한 자체 제작 보드에서 대해 설명한다. PDP is watched as a wall-mounted nat displayer for merits, such as ability to visual maximize and natural color reproduction. But it is more necessary to research video quality why PDP is competing with another displayer. This paper is explaned HDL software architecture implementaion for PDP lest-bed module and producing board using FPGA to research 42" PDP video quality.

In Korea, the public financial functions at local government are so much influenced by the central government's aid. In terms of that, to maintain the local autonomy system, the local government needs its finance autonomy whether to increase local tax or non-tax income. The local governments, however, prefer a policy increasing non-tax revenue based on user or profiter to increasing tax revenue. The reason is that the policy of local government has an advantage of non-resistance revenue source relatively in that the local non-tax revenue is related to profiter's burden, without imposing additional taxes to the residents. The current non-tax revenue can be an effective means of securing local government's self-reliance from the financial perspective. That is, the current non-tax revenue takes an important factor to improve the power of local government's finance because it can serve as a kinds of own revenue. Under the circumstance, the purpose of this study is to investigate the way of expanding local current non-tax revenue, as a source of own revenue, through the case of 23 local governments in Kyung Buk province. The results of this study focus on the improvement of current non-tax revenue policy at local government. They can be summarized with the perspectives related to some reforms: 1) readjustment of current non-tax revenue system, 2) reinforcement of professional educationㆍtraining for public servant in charge and developing the new sources of current non-tax revenue, 3) operation of a reasonable rate system for user or profiter, 4) improvement of collecting system and reinforcement of lew for arrears after computerization, 5) solution for severe disproportion of current non-tax revenue size between local governments, and 6) revitalization of local economy.
