The results of this study are as follows: First round final male (13.89 ± 3.86), Female (9.78 (16.33 ± 5.21), female (11.44 ± 2.54), semi-final male (15.50 ± 7.71), female (8.20 ± 2.18), and female . (13.44 ± 1.39), female (13.67 ± 6.84), semi-final male (10.42 ± 5.19) and female (13.20 ± 2.03) were the highest on the average. In addition, the order of kicking the first round male player is the paw cut foot (4.00 ± 1.00) in the finals. In the semi-finals, the front kick was kicked (2.97 ± 2.22). The female athlete performed side kick (6.22 ± 3.75) and side kick (5.47 ± 4.30) in both the final and semi-final stages. In the second round final, in the semi-finals, the paw cuts (8.67 ± 6.43) and the paw cuts (2.97 ± .57). The female athlete performed side kick (4.22 ± 3.53) in the finals, and front foot cut (3.80 ± 2.54) in the semi-finals. In the third round final and semi-finals, the front foot cut (4.00 ± 1.00) and the front foot cut kick (2.97 ± 2.22) were found to be sideways in the final (5.22 ± 3.95) and the front foot cuts (5.33 ± 3.82) in the semi-finals . However, there was no significant difference between the final and semi-final comparisons. In conclusion, both male and female athletes have the advantage of being able to attempt a series of attack techniques such as a kick and a fast kick using speed. 본 연구는 태권도 국가대표 국제무대 결승, 준결승 선수들의 경기 시 발차기 기술 분석을 알아봄으로써 경기운영 전략과 훈련 프로그램 개발에 기초자료를 제시하고자 하였으며, 이에 대한 결과는 1라운드 결승전 남(13.89±3.86), 여(9.78±.19)로 준결승 남(16.00±13.47), 여(8.87±1.21). 2라운드 결승전 남(16.33±5.21), 여(11.44±2.54). 준결승 남(15.50±7.71), 여(8.20±2.18). 3라운드 결승전 남(13.44±1.39), 여(13.67±6.84), 준결승 남(10.42±5.19), 여(13.20±2.03)모두 돌려차기가 평균적으로 가장 높게 나타났다. 이밖에 1라운드 남자 선수 발차기순서는 결승전에서 앞발 커트발(4.00±1.00). 준결승전에서 앞발 커트발차기(2.97±2.22)를 여자 선수는 결승, 준결승전 모두에서 옆차기(6.22±3.75), 옆차기(5.47±4.30)를 실시. 2라운드 결승, 준결승전에서 앞발 커트발차기(8.67±6.43), 앞발 커트발(2.97±.57). 여자선수는 결승전에서 옆차기(4.22±3.53), 준결승전에서 앞발 커트발(3.80±2.54)를 실시. 3라운드 결승, 준결승전에서 앞발 커트발(4.00±1.00), 앞발 커트발차기(2.97±2.22) 여자선수는 결승전에서 옆차기(5.22±3.95), 준결승전에서 앞발 커트발(5.33±3.82)를 실시한 것으로 나타났다. 하지만 결승, 준결승 비교분석은 유의한 차이가 나타나지 않았다. 결론적으로 남녀선수 모두 돌려차기와 스피드를 이용한 빠른 발차기 등 연속된 공격기술을 시도할 수 있는 장점이 있어 가장 많이 사용하는 것으로 판단된다.

PWM制御 單相 能動 交流電力필터에 의한 高調波 著減에 關한 硏究

A closed­loop control system to reduce the harmonics required by PWM controlled single phase Active AC power filter is proposed. The instantaneous harmonics which consist of both displacement of fundamental current and harmonic distortion current is measured and compensated by Active power filter connected parallel between power lines and nonlinear load. A combination of a D.C choke and a transistor Inverter is used for the Active power filter. The principal and the construction of the control system are presented as well as some experimental results. The results are obtained as follows. 1) The reactive power including both displacement of fundamental current and harmonics distortion current of 1.5[KHz] and below can be eliminated. By the use of closed―loop control, the accuracy of compensation is excellent. 2) The voltage fluctuation of power supply is not disturbed, because the power is improved from 0.65 to 0.96 by the use of Active power filter. 3) Fast response of 8.3[㎳] for quick changes of the load can be attained. 4) Because of using a power transistor as the switching element of the current type PWM Inverter, the compensating time is more improved and commutation loss in Inverter becomes nearly zero. 5) In order to eliminate harmonic current of more than 1.5[KHz], the PWM Inverter using as Active power filter must be multi―current type.

Purpose: To date, much research has been performed for amelioration of secondary brain damage after cerebral ischemia and reperfusion. We investigated the antioxidative and anti-inflammatory effects of post-ischemic low-dose total-body irradiation (TBI) on transient global cerebral ischemia. Methods: The gerbils were divided into six groups (8 gerbils in each group): group Ⅰ and Ⅱ, sham operation; group Ⅲ and Ⅳ, 10-minutes ischemia without TBI; group Ⅴ and Ⅵ, 10-minutes ischemia with TBI at 10 minutes after reperfusion. The activity of superoxide dismutase (SOD) and the levels of myeloperoxidase (MPO) and malondial-dehyde (MDA) in the brains of group Ⅰ, Ⅲ, and Ⅴ at 4 hours after reperfusion were measured. In the brains of group Ⅱ, Ⅳ, and Ⅴ, the levels of MPO and MDA were measured and the hippocampal areas were stained with hemotoxylineosin (H-E) and TUNEL at 5 days after reperfusion. Results: The activity of Cu/Zn SOD in group V was significantly increased compared to that in group Ⅲ, but their activities were significantly lower than that of group Ⅰ. The MPO and MDA levels in groups Ⅴ and Ⅵ were significantly lower than that of group and Ⅳ. The percent dead neurons found in the hippocampal CA1 region by using H-E staining was significantly lower in group VI than in group Ⅳ. The number of TUNEL positive cells in the hippocampal CA1 region was significantly lower in group Ⅵ and in group Ⅳ. Conclusion: Anti-oxidative and anti-inflamatory responses induced by post-ischemic low-dose TBI may reduce secondary neuronal damage following 10 minutes of transient global cerebral ischemia.

Traditionally, the model for power switching circuits at harmonic frequencies connected to an ac system has been an ideal current source. The magnitudes of the currents at each frequency are derived from the anaiysis of idealized current waveform. These currents are injected into the ac system to determine the resonant frequencies and harmonic penetration into the system. A more accurate model for frequency plane analysis is proposed and it is applied to a static VAR compensator(SVC) consisting of a fixed capacitor in parllel with a thyristor controlled reactor(FC­TCR). This model consists of a harmonic voltage source in series with a variable source admittance. The differential equations for the system are first written in order to gain a better insight to the problem. The model is hypothesized and the circuit is analyzed to determine its parameters. Finally, the results of a model test is shown which verify the accuracy of the model.

본 연구에서는 조향모터의 실시간 모니터링 시스템 절차를 제안하였다. 이를 위하여, Craig-Bampton 기법에 기반한 역동역학 절차를 적용하여 소수의 계측데이터로 미계측 응답을 추정하였다. 해당 시스템은 모터와 지그 사이 결합 반발력의 계측값과 추정값을 비교하여 검증하였다. 나아가, 효율적인 모니터링 시스템을 위하여 혼합현실에서의 시각화 시스템을 구축하였다. 시각화 시스템에서 모터의 형상은 그래픽 렌더링을 통해 구축하였고, TCP/IP 데이터 통신으로 모터의 변위 및 모터와 지그 사이 결합 반발력을 실시간으로 업데이트하였다. This paper presents a new virtual sensing system for the real-time monitoring of a vehicle steering motor. The aim of the proposed system is to identify the unmeasured dynamic characteristics of the target structure using the inverse force identification method. The system matrices (mass, stiffness, and damping) of the steering motor vibration are generated using the finite element (FE) method, model update approach, and the well-known Craig-bampton reduced-order method. The implicit inverse force identification method is subsequently integrated with the system matrices to predict the unmeasured loading state based on a limited set of measurable acceleration data. Finally, forward time integration provides the full vibration responses and reaction forces of the entire structure. The accuracy and efficiency of the proposed system are examined by the experimental study. The utilization of HoloLens visualization software is implemented in the proposed virtual sensing system for human perception. TCP/IP data connection is then employed to guarantee the attainment of real-time functionality. The user can effectively monitor the physical condition of the target structure using the mixed reality environment.

디지탈 인코더의 符號化 技法에 關한 硏究

朴奎南 順天大學校 1985 論文集 Vol.4 No.1

Cyclic codes are often used in encoders to avoid possible ereoneous readings. Special attention must be paid to codes where changes in certain digits are irreular. A new cyclic encoding scheme for a degree-reading encoder is propoesd in this paper. While keeping the encoding simple and effcient, the method considerably reduces the external decoding circuit requirements.
