혁신제품의 성패는 시장 개척의 성공 여부에 따라 결정되는 경우가 많다. 창업기업 및 벤처기업이 제품 혁신을 통해 무한 경쟁법칙이 존재하는 다윈의 바다에서 성공 하도록 하기 위한 혁신적 조달정책이 부각되고 있다. 시장 창출을 지원하기 위한 혁신적 조달정책의 이론적 근거는 진화경제학 방법론이 가장 적합하다. 진화경제학은 시장을 지식 조정 메커니즘으로 인식하기 때문에 혁신제품의 수요자와 공급자 간의 상호작용을 통해 시장은 진화한다고 주장한다. 본 논문은 전기자동차가 시장에서 선택되고 확산되는 것을 지원한 선전시의 혁신적 조달정책을 진화경제학 방법론에 기초하여 분석하였다. 선전시의 전기자동차 시장 개척을 위한 혁신적 조달정책은 3단계로 구분되어 진행 되었다. 전기자동차 시장 형성을 위한 사전 논의 단계, 얼리어답터 단계, 구매 확장 단계의 3단계를 통해 BYD 기업을 세계 1위 전기자동차 기업으로 발전시키는데 기여하였다. 선전시의 전기자동차 사례는 혁신제품의 시장 개척을 위한 혁신적 조달정책의 중요성을 시사하고 있다. The survival in a market has a great effect on the success or failure of innovative product. It is very important for a government to implement the public procurement of innovation in order to support a startup or venture with an innovative product to survive in the Darwinian sea. The evolutionary economics provides a theoretical methodology to the public procurement of innovation of creating a market. Because the evolutionary economics recognizes a market as a mechanism of coordinating knowledge, a market is perceived to evolve as a buyer and supplier of innovative product interact to coordinate knowledge. This paper investigates Shenzhen's public procurement of innovation of creating electric vehicle market based on the methodology of evolutionary economics. Shenzhen's public procurement of innovation has been implemented with 3 steps: origination(deep coordination), adoption(surface coordination), retention(operational coordination). Shenzhen's public procurement of innovation has contributed to BYD company which has grown as the biggest electric vehicle firm in the world. Shenzhen's public procurement of innovation suggests a variety of policy implications for creating a market of innovative product.
A series of bis-orthometalated monocyano Ir(III) complexes, [Ir(ppy)2PX3CN], (X¼ Oph, Ph and n-bu) were synthesized and theinuence of the steric and electronic eects of the phosphine ligand on the photophysical and electrochemical properties of com-plexes were studied. These cyano phosphine complexes emit light from an admixture of triplet metal-to-ligand charge-transfer(3MLCT) and ligand centered (LC) states in the region of 455498 nm with a vibronic progression. The trends of the photophysicaland electrochemical properties of metal complexes in the series were well understood by the electronic parameter of the phosphineligands. Polymer light emitting devices were fabricated by doping Ir(ppy)2P(n-bu)3CN in the PVK host and the device performanceswere investigated. The maximum external quantum eciencyðgexÞwas 1.45% for a 10wt% Ir(ppy)2P(n-bu)3CN doped PVK device.A power eciency of 0.99 lm/W at 230 cd/m2 and 6 mA/cm2 was obtained. The corresponding chloro complexes of the generalformula [Ir(ppy)2PX3Cl] were also synthesized and the optical and device properties were compared with the cyano complexes..
The purpose of this study was to measure empathy in physical therapy students using a self-report measure of empathy. One hundred seventy students from three different majors participated in the study. The physical therapy group consisted of 49 people, 24 men and 25 women. The psychotherapy group has 59 people, 17 males and 42 females. 62 participants were randomly assigned to the engineering group, with 18 males and 44 females. It was hypothesized that empathy would be higher in physical therapy students compared to those in engineering. Empathy Quotient (EQ) supported the research hypothesis, with students in physical theapy higher than students in engineering There is no statistically significant difference in the EQ between physical therapy and psychotherapy. There were also differences in empathy according to major and gender. Our research suggests that empathy needs to be promoted through education and training.
Purpose: We investigated how nerve mobilization influence ankle plantar flexor muscles of the affected lower extremity on the spasticity in stroke patients. Method: Total 12 patients were recruited, who had spasticity on ankle of the affected lower extremity, and applied nerve mobilization on the sciatic and tibial nerves in supine position. H-reflex was measured using EMG equipment, detected the ratio of maximum H/M and H-reflex latency, and compared the changes before, during, right after, 5 minutes after and 10 minutes after the application of nerve mobilization. The data were analyzed using repeated measure ANOVA to compare the changes in length of time. Results: In comparison with the ratio before nerve mobilization, the ratio of maximum H/M was significantly decreased during nerve mobilization(p<0.05), and it tended toward recovery right after, 5 minutes after and 10 minutes after applying nerve mobilization, there was no statistically significant difference(p>0.05). In comparison with the ratio before nerve mobilization, the ratio of maximum H/M was most significantly decreased during the first 10 seconds after nerve mobilization and it tended toward recovery gradually(p<0.05). In comparison with the H-reflex latency before nerve mobilization, it was significantly increased during nerve mobilization(p<0.05) and it was decreased right after nerve mobilization, After 5 and 10 minutes, it had a tendency toward recovery but it revealed no statistically significant difference (p>0.05). Conclusion: It is considered that nerve mobilization could contribute to initial rehabilitation with stroke patients for relieving spasticity and nerve contracture.
In this work, the electrical bistability of an organic CT complex is demonstrated and the possible switching mechanism is proposed. 2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) and tetracyanoquinodimethane (TCNQ) are used as an organic donor and acceptor, respectively, and poly-methamethylacrylate (PMMA) is used as a polymeric matrix for spin-coating. A device with the Al/(Al2O3)/PMMA:BCP:TCNQ[1:1:0.5 wt%]/Al configuration demonstrated bistable and switching characteristics similar to Ovshinsky switching with a low threshold voltage and a high ON/OFF ratio. An analysis of the current-voltage curves of the device suggested that electrical switching took place due to the charge transfer mechanism.
