This study analyzes wireless transmission efficiency in magnetic resonance topology. In wireless power transmission systems, the overall efficiency is limited by the power consumption of coils. To improve the efficiency of wireless power transmission systems, this study proposes a suitable design for implantable devices by studying the shapes of coils, the distance between them, and the transmission media. Results show that efficiency declines as the distance between coils increases. Good efficiency is achieved under long-distance transmission when coils with large radii are used in transmitters. At short distances, small coils achieve better efficiency than large coils. The measurement results under an emulated human body experiment show that skin thickness is the key factor in transmission efficiency. The transmission efficiency under a pig skin thickness of 9 mm is 0.799% lower than that under the air medium.

This study is based on resonant wireless power transfer with the type of series to series (S-S) in hope to discuss the status and simplified particular solutions of dual antennas for transmission. The Concentric Flat - Plate (CFP) antenna is used in this study and interaction of electromagnetic waves during transmission makes it difficult to predict the reception result. Analyzing the interaction of two electromagnetic waves during transmission makes it easy to predict the reception result also understand the transmission mechanism clearly. Complex mathematical equations require computer simulations to produce results but solve the analytical solution using in time domain's method. The solutions in this paper can precisely prediction the attenuation using in WPT system based on specific signal frequency working at 13.56 MHz which is included in ISM band. The working frequency is set to the resonant frequency. The result is very useful in WPT system with the result. Compared the results with simulation to demonstrate the solution.

The paper aims for studying the relationship between consumers? attachment styles and consumers? behaviors, especially ethical consumption and conformity consumption. Based on combing the previous researches, studies conclude that: “secure attachment” people and their ethical behaviors are most positively related, and “ambivalent attachment” people and their moral behaviors take second. Meanwhile, “avoidant attachment” people and their moral behaviors are most negatively related, and “fearful attachment” people and their ethical behaviors take second. And “secure attachment” people will be easier to be affected by “informational social influence” aiming at obtaining knowledge; however “insecure attachment” people will be easier to be affected by “normative social influence” aiming at obtaining social supports. Of course, those propositions need further empirical research.

Our paper aims for studying the effect of entrepreneur spokesman' charitable behaviors on purchase likelihood. Empirical Studies demonstrate that: Entrepreneur's charitable behaviors significantly increase consumer's purchase likelihood by donating money or time. The positive effect of entrepreneur's charitable behavior is mediated by consumers' self-importance of moral identity (CSIMI). Specifically, donating money is more effective on purchase likelihood for consumers who are low level in CSIMI; while donating time is more effective on purchase likelihood for those who are high level in CSIMI. The effect of donating money and time on purchase likelihood are moderated by consumer's perception on entrepreneur's personal image.
