A limb movement function evaluating method and the implantation system are provided. The aforementioned system includes a limb fixing device, limb guiding device, driver, actuator, impedance detector, and movement function analyzer. The limb fixing device is used to fix the first end of the user limb. The driver is used to guide the second end of the user limb through the actuator so as to make the second end moving relatively to the first end. The impedance detector is further connected to the driver so as to measure mechanical impedance where the movement of the user limb responses to the driving point of the driver. Finally, the limb movement analyzer compares the measured mechanical impedance and the movement path of the user limb so as to form a limb movement function curve. Therefore, the medical staff can make accurate rehabilitation evaluation according to the limb movement function curve.

The present invention relates to a biodegradable nanocomplex. The biodegradable nanocomplex comprises a first electrically charged substance, a charge-redistribution substance, a second electrically charged substance and a carried substance, for holding the carried substance inside. The first electrically charged substance and the carried substance have the same electrical polarity, and the biodegradable nanocomplex has a nonuniformally and positively charge distribution along a radial direction thereof. The nonuniformally and positively charge distribution comprises a first electrically charged portion having substantially electrical neutrality, a second electrically charged portion surrounding the first electrically charged portion, and a third electrically charged portion surrounding the second electrically charged portion, in which the third electrically charged portion comprises an outermost surface of the biodegradable nanocomplex, thereby modulating the carried substance towards the desired immune responses via the nonuniformally and positively charge distribution.

A photonic microwave generation apparatus and a method thereof are disclosed. A comb-like optical signal generation module of the photonic microwave generation apparatus generates a comb-like optical signal. The comb-like optical signal is injected into a photonic microwave generation module of the photonic microwave generation apparatus, wherein the photonic microwave generation module includes a microwave generation laser. An optical power and a carrier frequency of the comb-like optical signal are adjusted so as to place the microwave generation laser in period-one nonlinear dynamics, and, at the same time, to phase-lock an oscillation sideband of the period-one nonlinear dynamics by one harmonic of the comb-like optical signal. Under such operation, the microwave generation laser emits an output optical signal that carries a microwave signal of a narrow linewidth and a stable frequency, which can be retrieved from the output optical signal by using a photodetector.

This study investigates the effectiveness digital game-based learning (DGBL) on students' problem solving, learning motivation.; academic achievement. In order to provide substantive empirical evidence, a quasi-experimental design was implemented over the course of a full semester (23 weeks). Two ninth-grade Civics and Society classes, with a total of 44 students (15-16 years old), were randomly assigned to one of two conditions: an experimental group (incorporating DGBL) and a comparison group (taught using traditional instruction). Two-way mixed ANOVA was employed to evaluate changes in problem solving ability and compare the effectiveness the two strategies, while ANCOVA was used to analyze the effects on learning motivation and academic achievement. The results of this study are summarized as follows: (1) The DGBL strategy was clearly effective in promoting students' problem solving skills, while the control group showed no improvement. Additionally, data from the mid-test and post-test demonstrate that, as a higher order thinking skill, problem-solving requires a full semester to develop. (2). DGBL resulted in better learning motivation for students in the experimental group as compared to learners receiving TI. (3) Contrary to some suggestions that digital games could inhibit academic achievement, no statistically significant difference was found between the two groups. Most importantly, the quantitative improvement in problem-solving and learning motivation suggest that DGBL can be exploited as a useful and productive tool to support students in effective learning while enhancing the classroom atmosphere. Future research in DGBL should emphasize the evaluation of other higher order elements of the cognitive domain in terms of academic achievement outcomes and skills, such as critical and creative thinking. © 2012 Elsevier Ltd.
