Correlation between apnea–hypopnea index and Tp-Te interval, Tp-Te/QT, and Tp-Te/QTc ratios in obstructive sleep apnea

[摘要] In addition to their ability to reach distant learners, interactive e-learning environments have the potential to make the teaching-learning process more effective. This paper highlights some of the e-learning implementation efforts at the Addis Ababa Institute of Technology (AAiT) in Ethiopia. This case study shows that limited resources do not deter a developing nation to exploit the power of e-learning. Based on feedback from participants in the first national videoconferencing program held in Ethiopian higher education system between October 2011 and June 2012, the paper addresses the lessons learned and recommended actions for moving forward to a successful implementation of e-learning in Ethiopia, particularly in a videoconferencing mode.
