Skill competence is essential for nursing students and experiential teaching method has become increasingly popular in China's nursing education. To systematically evaluate the effects of experiential teaching method on the development of nursing students’ skill competence, and to provide evidence for nursing education.

Enhanced resistive switching phenomena of IrO/GdO/W cross-point memory devices have been observed as compared to the via-hole devices. The as-deposited GdO films with a thickness of approximately 15 nm show polycrystalline that is observed using high-resolution transmission electron microscope. Via-hole memory device shows bipolar resistive switching phenomena with a large formation voltage of -6.4 V and high operation current of >1 mA, while the cross-point memory device shows also bipolar resistive switching with low-voltage format of +2 V and self-compliance operation current of <300 μA. Switching mechanism is based on the formation and rupture of conducting filament at the IrO/GdO interface, owing to oxygen ion migration. The oxygen-rich GdO layer formation at the IrO/GdO interface will also help control the resistive switching characteristics. This cross-point memory device has also Repeatable 100 DC switching cycles, narrow distribution of LRS/HRS, excellent pulse endurance of >10,000 in every cycle, and good data retention of >10 s. This memory device has great potential for future nanoscale high-density non-volatile memory applications. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the outcome of endodontic microsurgery and analyze the potential prognostic factors, and to evaluate the value of surgical classification by Kim and Kratchman., Methods: Collecting clinical examination and radiographical examination of endodontic microsurgery cases (which were followed up at least 1 year), which were classified according to Kim and Kratchman, and we analyzed the outcome of endodontic microsurgery and its potential prognostic factors., Results: 302 patients (400 teeth) who received endodontic microsurgery were included. The one year success rate of endodontic microsurgery was 94.25%. Different classification had significant influences on the outcome of endodontic microsurgery ( P <0.05), and the success rate of class B and C were better than those of class D, E, and F. The position of teeth had significant influences on the outcome of endodontic microsurgery ( P <0.05). The success rate of maxillary teeth was higher than that of mandibular teeth. The success rate of anterior teeth was higher than that of posterior teeth ( P <0.05). The quality of root end filling and first or second surgery had no effect on the outcome ( P >0.05)., Conclusions: Endodontic microsurgery is an effective treatment method for saving affected teeth, and it can get a good result. Tooth position and classification are the potential prognostic factors. The surgical classification of Kim and Kratchman can help to predict the outcome of endodontic microsurgery.
