Learner attention affects learning efficiency. However, in many classes, teachers cannot assess the degree of attention of every student. When a teacher is capable of addressing inattentive students immediately, he can avoid situations in which students are inattentive. Many studies have analyzed student attentiveness by the applying of image detection(More)
BACKGROUND When heat is applied to the skin, it is dissipated due to conductive heat flow in the tissue and the blood. While heat flow has been studied after applying a single heat exposure, the physiology of repeated exposures to local heat has not been well investigated. MATERIAL/METHODS Twenty male and female subjects in the age range of 20-65 years(More)
Distance education courses must cope with the difficulties imposed by delivering a class at a distance. As most courses only emphasize the cognitive aspects of the class and neglect the course's effect on the students, this gives no help for reaching the affective domain teaching goals. Especially for younger students, in distance education, when younger(More)

Distance learning is one of the common education methods. Its advantage lies in that the student can learn at anytime or anyplace. However, such a learning mode relies highly on the dependence of the student. Under different environments and conditions, not all the students can be attentive. In this research, an auto-detection system has been designed,(More)
Secure user authentication without repeating registration is one of the important issues in multi-server networks that needs to be adequately addressed. Recently, two-factor (smart card and password) based remote user authentication protocols have been widely introduced due to their low constructional cost and convenient usability for the authentication(More)
Distance learning is a learning style that can overcome the limitation of time and space. Because of the distance, teachers can not assess the achievement of Affective Domain teaching goal. If teachers can know the student's affective state through the learning system, they can overcome the difficult. The research applies the image recognition technologies(More)
