Abstract: The aim of this paper is to present an innovative teaching approach using a troubleshooting methodology in teaching and learning microprocessors by trainees at technical high schools. Moreover, this paper presents the evaluation of this methodology by electronics teachers who teach at technical high schools. In the beginning, the basic theoretical background about the troubleshooting problem-solving and a literature review about teaching microprocessors are described. Here is a detailed description of the troubleshooting methodology for teaching microprocessors to a real-world problem through a simulator. The methodology was presented in a seminar of teacher professional development for improving the quality of teaching electronic technology at technical high schools, and in the end up, a questionnaire for the evaluation of this methodology was given to the participants in order to express their opinion. The participants consider that the proposed methodology for the teaching microprocessors is appropriate for their students, and that the learner-centered approaches, in general, attract students' interest and they have better learning outcomes.

Abstract: The topic of festival effect on costumer buying behavior is an important issue to the company. One of the most significant features of the total product is the place where it is bough or consumed. In some cause, the place, more specifically the atmosphere of the place, is more influential than the product itself in the purchase decision. To improve customer purchase, many stores spend a lot of time to demonstrate special merchandise display in festival to attract customers. In the paper, we focus on merchandise display and emotional contagion to explore display of goods to perceived value and emotional contagion to mood, and their effects on customer impulsive buying. We use experimental method to manipulate merchandise display of store (festival display store / no festival display store) and emotional contagion (with emotional contagion environment / no emotional contagion environment) and to measure perceived value and impulsive buying with Likert scale. We infer that the store with festival merchandise display and emotional contagion environment will effect on impulsive buying.

Abstract: The paper designed a portable four-channel lung sounds acquisition system. The system first completed the lung sound signal amplifying, filtering and other pretreatment, then the lung sound signals of the pretreatment were sent to the external A/D chip for sampling, the acquisition of lung sound signals were saved as the. WAV audio file stored in the SD card, finally, using the short time Fourier transform to complete the time-frequency domain analysis of lung sound signals. Through the system can accurately detect the patient's lung sound signals, and using the stereo headphones can realize synchronous auscultation of the patient.
