The purpose of this study was to compare shear bond strength adhesive resin cements on dentine which had been in contact with provisional cements prior to dentine bonding. The shear bond strength of types of Resin cement to dentin were Measured in control group and after the application of two types of temporary cements. The samples were covered with Cavitec(eugenol-containing), Temp-bond NE(eugenol-free). All specimens were stored in saline for 10 days. After removing the provisional cements with scaler, the dentin surface was cleaned with non-fluoridated flour of pumice Cobalt-chromium alloy(Biosil F, Degussa Co., Ltd, Germany) were bonded to dentin surfaces after pretreatment with the resin cements. Shear bone strengths were measured using UTM at a crosshead speed of 1㎜/min. The obtained results were as follows : 1. Temporary cement (eugenol & non-eugenol) application significantly decreased the shear bond strength in all resin cements. 2. No significant difference was found between the shear bond strength of Cavitec (eugenol) and Temp - bond NE (non eugenol). 3. There was no difference in shear bond strength between Super-bond C & B and Bistite resin cement. 4. The adhesive failure phenomenon has been observed within the group used the temporary cement, whereas the adhesive failure and the cohesive failure had been surveyed within the other group at the same time

Purpose: This study aims to identify the factors that affect the expected frequency of performance and the importance in nursing practice of total care service recognized by nursing college students. Methods: This is a descriptive study. A self-administered questionnaire survey was conducted on 288 nursing students of E university and data was collected and analyzed using the SPSS program. Results: The average scores for the expected frequency of performance and the importance in nursing practice of total care service were $4.07{\pm}0.58$ and $4.00{\pm}0.50$ respectively. The expected frequency of performance was found to have a significantly positive correlation with the importance in nursing practice. Additionally, the factors that influenced the degree of recognition in the expected frequency of performance and the importance in nursing practice of total care service among nursing students were comfortable care and respiratory care, respectively. Conclusion: The major finding of this study shows a significantly positive correlation between the expected frequency of performance and the importance in nursing practice. These results suggest that effective and systematic education is needed on factors affecting the expected frequency of performance and the importance in nursing practice for nursing college students.
