이진복,임정균,조이현,김종욱,육태한,송범용,Lee, Jin-Bok,Cho, Yi-Hyun,Im, Jeong-Gyun,Kim, Jong-Uk,Yook, Tae-Han,Song, Beom-Yong 대한약침학회 2010 Journal of pharmacopuncture Vol.13 No.3
Objective : This study was to investigate the clinical effect of Rubiae Radix pharmacopuncture on knee joint pain. Methods : The patients were treated by Rubiae Radix pharmacopuncture, Acupuncture, herbal medicine. To evaluate the effect of the treatment, The patient's symptoms were assessed by Visual Analogue Scale(VAS) Score, Knee injury and osteoarthritis outcome score(KOOS) and physical examinations. Results : In all cases, the pain was reduced significantly according to improvement of VAS score, KOOS and active Range Of Motion(ROM) of knee joint. VAS score and KOOS of all cases were decreased. In two cases, ROM of knee joint has improved. But in one case, ROM of knee joint has still been restricted. But there are no noticeable changes in physical examinations. Conclusion : These results suggest that Rubiae Radix pharmacopuncture might be an effective method to treat patients with knee joint pain. But, It's necessary to have more observations and experiments with Rubiae Radix pharmacopuncture.
PI-LEAD 알고리즘을 이용한 2축 안정화 짐벌 시스템 제어
이진복,최한고,Lee, Jin-Bok,Choi, Han-Go 한국융합신호처리학회 2013 융합신호처리학회 논문지 (JISPS) Vol.14 No.2
서보 시스템에서 마찰과 같은 비선형 요소는 측정이 어려우며, 또한 정확한 예측이 어려워 보상하기가 쉽지 않다. 특히, 2축 안정화 짐벌 시스템에서 마찰은 큰 오차를 발생시켜 최종적으로 제어 성능을 만족시키지 못한다. 이와 같은 문제점을 해결하기 위해 관측기 등을 적용한 마찰 보상 연구가 많이 진행되어 왔으나 특정 조건에서만 적용되어 군수 분야에서 정밀도를 요하는 2축 안정화 짐벌 시스템에 적용하는데 제한적이다. 본 논문에서는 가장 일반적이면서 강인성이 입증된 PID 알고리즘을 변형시킨 PI-LEAD 알고리즘을 사용하여 모델링 및 시뮬레이션을 통해 마찰 보상 효과를 입증하고, 실제 2축 안정화 짐벌 시스템에 적용하여 효과를 검증한다. 성능시험을 통해 PI-LEAD 알고리즘이 마찰에 의한 오차를 최소화하여 정밀 서보 시스템에서 요구하는 성능을 만족하는 것을 검증하였다. Since the nonlinear factors such as friction in a mechanical servo system can't be easily measured nor estimated accurately. Therefore, it is difficult to compensate friction correctly. Friction makes a significant error in a 2-axis stabilized gimbal system and finally fails to reach the ultimate control performance goals. To solve these problems, lots of studies on the control methods applying observer have been performed. However, these methods can be used in specific conditions and are limited to apply them to the accurate 2-axis stabilized gimbal system in military sector. This paper deals with the PI-LEAD algorithm which is modified with a general and robust PID algorithm, proves the effect of the algorithm through modeling and simulation, and verifies the performance by applying the algorithm to the real 2-axis stabilized system. It is verified through the performance test that the PI-LEAD algorithm minimizes the error caused by friction and meets requirements of the accurate servo system.
RF 마그네트론 스퍼터링에 의한 ZnO박막의 증착 및 구리 도우핑 효과
이진복,이혜정,서수형,박진석,Lee, Jin-Bok,Lee, Hye-Jeong,Seo, Su-Hyeong,Park, Jin-Seok 대한전기학회 2000 전기학회논문지C Vol.53 No.12
Thin films of ZnO are deposited by using an RF magnetron sputtering with varying the substrate temperature(RT~39$0^{\circ}C$) and RF power(50~250W). Cu-doped ZnO(denoted by ZnO:Cu) films have also been prepared by co-spputtering of a ZnO target on which some Cu-chips are attached. Different substrate materials, such as Si, $SiO_{2}/Si$, sapphire, DLC/Si, and poly-diamond/Si, are employed to compare the c-axial growth features of deposited ZnO films. Texture coefficient(TC) values for the (002)-preferential growth are estimated from the XRD spectra of deposited films. Optimal ranges of RF powers and substrate temperatures for obtaining high TC values are determined. Effects of Cu-doping conditions, such as relative Cu-chip sputtering areas, $O_{2}/(Ar+O_{2})$ mixing ratios, and reactor pressures, on TC values, electrical resistivities, and relative Cu-compositions of deposited ZnO:Cu films have been systematically investigated. XPS study shows that the relative densities of metallic $Cu(Cu^{0})$ atoms and $CuO(Cu^{2+})$-phases within deposited films may play an important role of determining their electrical resistivities. It should be noted from the experimental results that highly resistive(> $10^{10}{\Omega}cm$ ZnO films with high TC values(> 80%) can be achieved by Cu-doping. SAW devices with ZnO(or Zn):Cu)/IDT/$SiO_{2}$/Si configuration are also fabricated to estimate the effective electric-mechanical coupling coefficient($k_{eff}^{2}$) and the insertion loss. It is observed that the devices using the Cu-doped ZnO films have a higher $k_{eff}^{2}$ and a lower insertion loss, compared with those using the undoped films.
