ABSTRACT
Medical Physics is an interdiscipline which is formed by applying the basic principles, methods, and techniques of physics to clinical medical research such as prevention, diagnosis, and treatment of human diseases, and it is a compulsory professional basic course for medical students. However, there are many medical students reflect that the content of this course is obscure and difficult to understand. Teaching effect is not ideal. The main reasons are that the teaching method is single and the reference materials are few. Based on the actual situation of the course, Hebei Medical University, China promotes formative evaluation from the content of teaching materials, teaching means, and other aspects. At the same time, by combining with the Internet, the digital construction has been realized, deepening the reform of the Medical Physics curriculum, and remarkable results have been achieved.
ABSTRACT
Objective:Through constructing an online question database of medical physics, teachers and students can make use of the Internet to realize interaction in or after class, so students' ability of independent learning and the quality of teaching can be improved.Methods:Based on teaching outlines, the type, quantity and difficulty of the test questions were discussed and determined by teachers in the teaching and research office, and the online question database of medical physics was constructed with the help of Internet platform to realize self-testing and teacher-student interaction.Results:Through the construction and application of online question database, students' learning initiative was mobilized, the effectiveness of teacher-student interaction was improved, and empirical materials for teaching formation evaluation were obtained. Self-examination and teacher-student interaction help improve students independent learning and problem solving ability. And data generated on the platform enable teachers to know students' learning situation and their teaching quality.Conclusion:The construction and application of Internet + digital online question database of medical physics can greatly promote the teaching effect.
ABSTRACT
We have developed a new wrist wearing heart rate monitoring alarm apparatus, which can detect the patients' real-time pulse waves. When the abnormal heart rate appears or pulse disappears, the monitoring alarm will sound and dial the remote telephone for help simultaneously. This apparatus uses the switch circuit to control the keyboard of mobile phone, and dials remote telephone in the help of mature technology and communication platform of mobile phones. The intelligent program can distinguish digital pulse signal, pick out the correct cycle of heartbeat intelligently. The new wrist wearing heart rate monitoring alarm apparatus will calculate an average heart rate when it captures consecutively five correct electrocardiograph waveforms. It really provides a simple, inexpensive and effective way for the patients with heart disease.
