Therefore, this study used data from the Special Needs Education Longitudinal Study in Taiwan, collected in the 2007-2008 academic year. There were 2,924 students with disabilities selected in the study who were placed in general classrooms; 855 were in preschool, 1,079 were in primary school and 990 were in junior high school. The questionnaires in the database were answered by their teachers. The results of this study are listed, as follows： In terms of the school support service model for students with disabilities in the three stages of education, adjustment in teaching accounts for 1-15% of the explanatory power regarding the overall model, while support services account for 63-85%, which peak in junior high schools. Secondly, itinerant teachers are found to be the most important human resource in preschools. For primary and junior high schools, parents and special education teachers are the more prevalent influences. The more common school support services are tuition refunds, itinerant services, adjustments in examinations, and scholarships.展开更多

It can transmit special information about users＇ location to front-end instantaneously, so it is very convenient for their daily life. It makes full use of the available wireless communication, which is easy to arrange and convenient for users.展开更多

Each system is connected to a repairable supporting external device for operation. Repairable service station is provided for immediate repair of failed unit. Explicit expressions for mean time to system failure and steady-state availability for the three configurations are developed. Furthermore, we compare the three configurations based on their reliability characteristics and found that configuration II is more reliable and efficient than the remaining configurations.展开更多
