본 논문에서는 0.18um CMOS 공정을 이용하여 두 종류의 10Gb/s급 광통신용 전치증폭기(TIA)를 설계, 비교하였다. 전압모드인 Inverter TIA(I-TIA)는 입력단에 inverter 구조를 사용하여 입력 유효 gm 값을 증가시킴으로써 입력저항 값을 줄이고 동시에 대역폭을 늘리는 효과를 얻었다. 0.25pF의 광다이오드 캐패시턴스에 대하여 $56dB{\Omega}$의 트랜스임피던스 이득과 14GHz의 대역폭을 얻었고, $10^{-12}$ BER과 9dB extinction ratio 및 0.4A/W responsivity를 예상할 경우 -16.5dBm의 광민감도를 얻었다. 그러나 기생 성분에 의한 대역폭의 감소 및 민감도가 크기 때문에 회로설계 시 패키지 및 회로내의 기생성분 효과에 대한 신중한 고려가 필요하다. 이와 달리, 전류모드인 RGC TIA는 입력단에 regulated cascode 설계기법을 사용하여 광다이오드와 TIA 사이에 생기는 큰 입력 기생 캐패시턴스를 전압모드보다 매우 효과적으로 차단하여 대역폭을 확장하였다. 또한 기생성분에 의한 대역폭 및 트랜스임피던스의 민감도가 현저히 줄어들어 대역폭의 변화가 없다. 0.25pF의 광다이오드 캐패시턴스에 대하여 $60dB{\Omega}$의 트랜스임피던스 이득과 10GHz의 대역폭을 얻었고, $10^{-12}$ BER과 9dB extinction ratio 및 0.5A/W responsivity를 예상할 경우 -15.7dBm의 광민감도를 얻는다. 그러나, I-TIA에 비하여 약 4.5배의 높은 전력소모를 보이는 단점이 있다.

Objectives : This research was performed to investigate the effects of Jodeungsan pharmacopuncture(PA-J) of focal brain ischemia induced by middle cerebral artery occlusion(MCAO) in rats. Methods : The subjects were divided into 4 groups : control, acupuncture, pharmacopuncture PA-J1(11.43 mg / 250 g / $40{\mu}{\ell}$) and pharmacopuncture PA-J2(2.29 mg / 250 g / $40{\mu}{\ell}$). The focal brain ischemia was induced by intraluminal filament insertion into the middle cerebral artery. After 3 days of MCAO, Jodeungsan pharmacopuncture treatment was performed on the GB20, and the day after being treated with pharmacopuncture, the Morris water maze test was carried out on the assigned group. The series of processes were administered 6 times. Thereafter mGluR5, density of neuronal cell and ChAT were measured. Results : The results were as follows. 1. The distance to target significantly decreased in the 2nd trial of the Acu group on the water maze test for short-term memory. 2. The distance to target significantly decreased in the 4th trial of the PA-J2 group on the water maze test for long-term memory. 3. The intensity of mGluR5 significantly increased in the PA-J1 group compared with the control group. 4. The neuroprotective effect on the hippocampal CA1 significantly increased in the PA-J1 and PA-J2 groups compared with the control group. 5. The density of ChAT in the hippocampal CA1 significantly increased in the PA-J1 and PA-J2 groups compared with the control group. Conclusion : These results suggest that Jodeungsan pharmacopuncture may improve memory and cognitive impairment and also have neuroprotective effects on focal brain ischemia.

Objective : This study was designed to estimate the effects of Rainbow Power therapy on neck pain patients by using Visual Analogue Scale(VAS) and pressure algometer. Methods : Rainbow Power therapy group consisted of 18 patients and acupuncture therapy group consisted of 7 patients. The degree of improvement of neck pain was evaluated by VAS and pain pressure threshold(at the points of Jianjing GB21 and Jianwaishu SI14) before treatment, before 3rd treatment and before 5th treatment. Rainbow Power therapy was performed at the points of Jianjing GB21, Zhongfu LU1, Yangxi LI5, Ganshu BL18, Weishu BL21 and Shenshu, BL23. Each points were stimulated with RP-UM103(Rainbow Power therapy instrument) for 20 seconds. The points of acupuncture therapy were Jeonggeun, Jeongjong, Sangbaekn and Hegu LI4 and acupuncture was maintained for 15 minutes. After above therapy dry cupping was performed at the points of Jianjing GB21, Jianwaishu SI14, Gaohuang BL43, Tianzong, SI11 and Bingfeng SI12 for 5 minutes. Results : There was no significant difference between the two groups in VAS, pain threshold of Jianjing GB21 and Jianwaishu SI14 following treatment. In the two groups VAS was significantly decreased. In Rainbow Power therapy group the pain threshold of the two points was significantly increased. But there was no significant increase in acupuncture therapy groups about the pain threshold of Jianwaishu SI14. Conclusions : The effectiveness of Rainbow Power therapy on neck pain was shown through VAS and pressure algometer. These imply that Rainbow Power therapy may be useful for neck pain. Further study is needed about Rainbow Power therapy.

This paper aims to investigate the axial compressive behavior of reinforced concrete (RC) columns strengthened with self-compacting and micro-expanding (SM) concrete-filled steel tubes (SM-CFSTs). Nine specimens were tested in total under the local axial compression. The test parameters included steel tube thickness, filling concrete strength, filling concrete type and initial axial preloading. The test results demonstrated that the initial stiffness, ultimate bearing capacity and ductility of original RC columns were improved after being strengthened by SM-CFSTs. The ultimate bearing capacity of the SM-CFST strengthened RC columns was significantly enhanced with the increase of steel tube thickness. The initial stiffness and ultimate bearing capacity of the SM-CFST strengthened RC columns were slightly enhanced with the increase of filling concrete strength. However, the effect of filling concrete type and initial axial preloading of the SM-CFST strengthened RC columns were negligible. Three equations for predicting the ultimate bearing capacity of the SM-CFST strengthened RC columns were compared, and the modified equation based on Chinese code (GB 50936-2014) was more precise.

Objectives The purpose of this study is to look into the methods of acupuncture for spastic cerebral palsy. Methods 27 cases of the clinical literature were selected from 43 studies about cerebral palsy and spastics. Theses literature were published between the January 2010 to September 2015 by using the China Academic Journal (CAJ) of China National Knoweldge Infrastructure (CNKI). Results Most studies mentioned the effect of acupuncture (scalp, general) or acupoint-injection, derma needle, warm acupoint. It was more effective with other herbal complex rehabilitation therapy such as acupuncture, physical therapy occupational therapy, rehabilitation, and the complex speech therapy than just the herbal therapy alone. Acupuncture of acupoint-injection has overall 86~96% of rehabilitation rate. The acupuncture was often used with the general acupuncture and scalp acupuncture. Commonly used major acupuncture points were sishencong (四神總), bohui (百會), yundongqu (運動區), and pinghengqu (平衡區), Li11, Li04, Gb39, St41. The main acupoint-injection points were fengchi (Gb21) and jiexi (St41). For the injection, brain actiator, astragalus injection, cerebroprotein hydrolysate, Vit B1, Vit B2 were commonly used. Conclusion Acupuncture and acupoint-injection have been shown as an effective treatment on spastic cerebral palsy. The acupuncture was used often with the general acupuncture and scalp acupuncture all together.
