In diabetic patients with hyperinsulinaemia, baseline DHEA levels are chronically and maximally suppressed compared to control subjects and non-hyperinsulinaemic diabetic patients, and thus not decreased further by exogenous insulin infusion during hyperinsulinaemic-euglycaemic clamp.

This paper is concerned with the development of an ultrasonic wave sensor system. A development of the sensor system a the robot which moves in the parallel to the wall is proposed. Ultrasonic wave frequency is 40 kHz. The sensor output is calculated with a PIC (computer), and it is displayed by a LCD screen. The architecture to introduce an ultrasonic wave sensor system for the moving environment is proposed. This architecture is simple, so it is applicable to measurement of the positioning control study. A sensor system was developed using only inexpensive and easily available components. Based on the information obtained while designing, manufacturing and testing the prototype, it was concluded that the system proved to be sufficiently capable for use by robots.

SUMMARYThis paper presents a new blended instruction model incorporating mobile-based e-Learning into a traditional nonwired classroom in foreign language teaching. The mobile tool adopted is iPod Touch. Our lesson was designed on the basis of the motivational model proposed by John M. Keller, which is widely known as the ARCS model. Our study considers the effect of this teaching model on students' vocabulary retention and oral speaking ability, and evaluates the course model in terms of the ARCS model, conducted at a Japanese national college of technology. The results suggest that the course stimulated the learners' interest sufficiently and changed the attitude of their learning strategies in a more communicative direction.
