Purpose: The purpose of this study was to compare the effectiveness of a structured preoperative PCA education to that of the usual informal teaching provided by hospital staff in alleviating postoperative pain through more effective use of PCA therapy. Method: As an advanced research, the knowledge about the use of PCA therapy and the attitude about the use of the pain medicine were estimated, and then as a later research, the knowledge about the use of PCA therapy, the attitude about the use of the pain medicine, and the score of the pain were estimated. Result: The experimental group those who received structured preoperative PCA education had statistically significant higher knowledge regarding the use of PCA therapy, the attitude about the use of he pain medicine, and the score of the pain were estimated. Result: The experimental group those who received structured preoperative PCA education had statistically significant higher knowledge regarding the use of PCA therapy(p=0.026) and more positive attitudes toward using pain medicine(p=0.004). The experimental group those who received structured preoperative PCA education reported better pain control 4(p=0.002), 8(p=0.014) and 24 hours(p=0.018) after the operation. Conclusion: The structured preoperative PCA education increases the knowledge for the use of patient's PCA therapy and changes their attitude toward the use of the pain medicine positively and consequently enable the use of PCA therapy to be more effective and then finally reduced the patient's pain after the operation.

Spinel-structured lithium manganese oxides are considered as promising cathode material, however, their widespread commercial application remains hampered by their poor surface instability. To overcome these problems, we designed and synthesized task-specific ionic liquid additives that can effectively scavenge trace amounts of fluoride in the cell. Addition of ionic liquid additives in the electrolyte significantly improves cycling retention. 1H- and 19F-nuclear magnetic resonance spectroscopy measurements and inductively coupled plasma mass spectrometry elemental analysis collaboratively provides clear evidence that the ionic liquid additives selectively suppress parasitic reactions of the electrolyte with the surface of lithium manganese oxides cathode.
