        김건형,이로민,남동우,김종인,임사비나,이두익,최도영,이윤호,이재동 경희대학교 동서의학연구소 2006 東西醫學硏究所 論文集 Vol.2006 No.-

        Objectives : To observe the effect of acupuncture treatment on Digital Infrared Thermographic Imaging(DITI) in frozen shoulder patients. Methods : 17 voluntary patients received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwanand Gyun-joong, twice a week for 4 weeks. The patients were instructed to practice self exercise during their daily lives. Evaluations were made before treatment, after 1 week of treatment, after 2 weeks, 3 weeks and after 4 weeks of treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). DITI was measured before treatment and after 4weeks of treatment. The obtained data was analyzed. Results : CSA, SPADI, VAS, adduction and extension showed significant(p<0.05) improvement. Abduction and flexion both improved after 4 weeks of treatment, but the improvement was statistically insignificant(p>0.05). DITI showed improvement but the improvement was insignificant(p>0.05). Conclusion : 4 weeks of acupuncture treatment significantly improved CSA, SPADI, VAS, adduction and extension in frozen shoulder patients(p<0.05). The improvement of abduction and flexion after 4 weeks of acupuncture treatment was insignificant(p>0.05). DITI results improved after 4 weeks of acupuncture treatment. But the change of thermal difference was insignificant(p>0.05).

      • 政治學方法의 體系的 分析 : 政治學의 本質認識을 中心으로 From the Perspective of the Orientation in Political Science

        盧東一 慶北大學校 1982 論文集 Vol.33 No.-

        The purpose of this paper is to analyze systematically the various kinds of methods which have been used in political science from the time of ancient Greece to the present. Methods in general are directly linked with the perception of it's ends itself, because it just implies the means achieving a certain given end. In the case of the methods of political science political science itself may be the end of it, because political science methods also implie the means for doing political science. Therefore how to perceive political science itself, namely the end of political science methods, is very important factor in systematic analysis of political science methods. In this regard, this paper analyzed the methods of political science from the perspective of the epistemological orientations in political science. The various kinds of methods of political science can be classified as the following four types: normative, instrumental, scientific, and analytic. As mentioned above these four types of methods are directly linked with the epistemological orientations in political science. A general and well-known distinction of the epistemological orientations in political science is among the traditionalism, behavioralism and post-behavioralism. There is a rough chronological order about them: phase 1: The traditional period, to 1945, phase 2: The behavioral period, 1945-1969, phase 3: The post-behavioral period, 1969-to the present. But more important to us is the fact that they are still in evidence today. Traditionalism perceives political science as philosophy of politics, therefore it uses mainly normative, instrumental, and analytical methods. It cannot be emphasized too strongly that traditionalism is a collection of perceptions lumped together today mainly because of a common enemy, behavioralism. Behavioralism, in contrast to traditionalism, perceives political science as science of politics, therefore it employs mainly scientific method. Post-behavioralism attempts to synthesize both behavioralism and traditionalism, so it recognizes equally the importance of the four types of the methods. Nowdays the orientation of post-behavioralism is widely acknowledged as an promizing alternative orientation. But the problem is that untill now no concrete political method to incarnate post-behavioral orientations is presented. Therefore, we must concentrate our effort on devicing a concrete political method to synthesize both philosophy of politics and science of politics.

      • PWM/PFM 제어형 DC-DC 콘버터에 관한 연구

        노채균,김동희,남승식,김성철 嶺南大學校 工業技術硏究所 1995 工業技術硏究所論文集 Vol.23 No.2

        As electionic application system such as data processing communication system and control measurement system get larger, high accuracy, high efficiency, small size and light weight for DC power supply are required. This paper processes a type of circuit that can be controlled by PWM and PFM-TRC method using Thyristor as switching element. And some data essential to system design are obtained by evaluating characteristic of the proposed circuit in terms of chopper frequency, energy storage period and load resistor using normalized parameter. The characteristic analysis of the proposed circuit is illustrated by experiment.

      • W-CDMA 망에서의 위치 서비스 기능 및 시스템 설계

        노철우,노문환,김동회,송평중 新羅大學校 2002 論文集 Vol.51 No.-

        The LoCation Services (LCS) feature in W-CDMA(Wideband CDMA) network provides the mechanisms to support mobile location services for operators, subscribers and third part service providers. The existing location positioning method are classified into the cell ID based, OTDOA, and network assisted GPS. A new hybrid location positioning method which combines three of these methods are proposed. We present the LCS funcition and system design using SDL (Specification and Description Language) and SDL development tool (SDT). This design covers the LCS functional model and signalling procedure, system architecture, data structrue, and process SDL diagram.

      • 北韓政治體制의 現況과 그 評價

        盧東一 경북대학교 사회과학연구소 1991 社會科學硏究 Vol.7 No.-

        The unification of south and North Koreas is one the most important problems which Korean people are facing. As everybody knows, the future of the unification will be largely dependent upon the characteristics of the political regimes of South and North Koreas. In such context, I am going to perform an intensive study on the present condition of the North korea's political regime and it's evaluation. In studying the present condition of the North Korea's political regime, I approached this problem by analysing the internal and mutual korea, namely, North Korea's Parliament. North Korea's Central Government, and North Korea's Labour Party. In this study, I evaluated the present condition of North korea's political regime on the basis of the democratic power structure. I collected the data for my study from books, articles and documents relating directly to my problem. Through this study, I found that all of the most important power is insititutionally given to Kim Il-sung and his son Kim -Jung-il. We can describe the existing power structure of North Korea as one man ruling power structure. This power structure is essentially different from the democratic power structure which Korean people have been regarding as the most idealistic form of power structure of the united Korea.

      • 엔드밀 가공에서 발생하는 절삭소음의 전파특성

        노승남,이동훈 서울産業大學校 2002 논문집 Vol.53 No.1

        This paper is to investigate the propagation characteristics of cutting noises from an end-mill machining process. The cutting noises are measured by a condenser microphone and analyzed by the narrow band and constant percentage bandwidth analyzer(FFT). The cutting conditions such as cutting speed, table speed and cutting depth are varied in the cutting noise measurements. The SM45C steel, GC200 cast iron, 6:4 brass and Al2017 aluminium are used as a workpiece for up end-mill machining, In addition, the hardness, tensile stress and damping ratio of workpieces are measured for obtaining the relationship between the material property of workpiece and the sound pressure level of cutting noise, From the cutting noise measurements, it is found that the sound pressure level of cutting noise increases with the cutting speed and the depth of cut as well as the damping ratio and hardness. Regardless of the kind of workpiece, it is also shown that the cutting noise is generated in frequency band between 2800Hz and 3600Hz.
