[Purpose] To report the effects of ankle balance taping for a patient with chronic ankle
instability (CAI). [Subject] A 33-year-old man with a 10 year history of chronic ankle
stability. [Methods] ABT with kinesiology tape was performed for 2 months (average,
16 h/day) around the right ankle. [Results] At the end of two months, no ankle instability
was noted when ascending and descending the stairs, jumping, turning, operating the pedals
while driving, and lifting heavy objects. [Conclusion] The repeated use of kinesiology
tape in ankle balance taping may be an effective treatment for recovering the ankle
stability of patients with chronic ankle instability.
A vertical GaN-light emitting diode (LED) has been fabricated on a sapphire substrate with periodic via holes formed by a laser drilling technique. n-contact metal which was deposited on the backside of sapphire substrate was directly connected with an Ohmic metal of n-GaN layer through the via holes. The via-hole-based vertical GaN-LED demonstrated an optical power improvement of up to 12.5% with lower forward operating voltage compared with a conventional GaN-LED. In addition, this vertical LED showed just 0.8% and 1.5% variations of optical power and operation voltage at the 500h reliability test.
A survey was conducted on the college students in the regions of Busan and Gyeongnam during a seven-month period of time from November, 2015, to investigate the level of their awareness of dental hygienist and their preference for the image of dental hygienist. The findings of the study were as follows: As for the level of awareness, the way of looking at dental hygienist was best among the health-related majors, followed by the commerce/economics majors, humanities/social sciences majors and natural sciences/engineering majors. Regarding the major work of dental hygienist, they gave top priority to cooperation for treatment, followed by scaling and counseling. As to educational level required for dental hygienist, 91.2 percent had the right understanding about that. As for the status of dental hygienist in the medical law, just 17.4 percent regarded dental hygienists as medical technicians, and 40.7 percent
We have proposed and fabricated a new GaAs FET with very short channel, which we call Floated Electron Channel Field Effect Transistor (FECFET), using the Selective Metal Organic Chemical Vapor Deposition (SMOCVD) technique. The channel length of the proposed device is reduced by placing the channel layer on the top of the triangular void. The formation of the triangular void is well characterized by both the growth parameters of the SMOCVD and the mask orientation. The maximum extrinsic transconductance of 260 mS/mm is obtained for the gate length larger than 2 µm and the measured source resistance is 0.25 Ω·mm. It is also observed that the measured transconductance is almost independent of the gate length when the fabricated gate has a length between 2.0 µm and 4.0 µm. The effective channel length is mainly determined by the short distance between two n+ layers for source and drain rather than the gate length. This device structure is suitable for low noise FET and for the simple realization of direct coupled FET logic inverter.
A GaAs/AlGaAs surface-emitting light-emitting diode (LED) and a vertical field-effect transistor (FET) are vertically integrated using the selective atmospheric pressure metalorganic chemical vapor deposition (MOCVD) technique. The embedded Schottky metal between the epitaxial GaAs layers is employed as the gate electrode of the vertical driver FET. As the drain current of FET flows through the LED, the light output of LED is effectively controlled by the gate voltage of the driver FET. This device operates as a three-terminal optoelectronic device controlled by an electric input.
