An experimental study of the tensile bonding strength of acrylic bone cement was carried out by using the tubular bones of 12 mongolian dogs. Following observations were made: 1. The later the cementing stage, the weaker was the tensile bonding strength of bone cement. 2. When saline or synovial fluid was interposed between the contact surfaces of the recipient bone and the cement, the tensile bonding strength of bone cement decreased by more than 50% of that when the bonding surface was dry. 3. When the bonded bone was stored in Hartmans solution, the tensile bonding strength of bone cement was reduced to 15–25% of the strength when stored in air.

OBJECTIVE: Seoul National University Bundang Hospital is the first full digital hospital with electronic medical record(EMR) system in Korea. We evaluated the user's satisfaction on the EMR system at 15 months from its beginning. METHODS: A total of 105 doctors and 503 nurses participated in this study. The questionnaire was composed of four domains: user satisfaction between paper records and EMR, User perceived improvement of work efficiency with EMR, user interface satisfaction and advantage/ disadvantage of EMR. A Likert-type 5-point scale was used for the degree of satisfaction, with 5 indicating 'very satisfied'. RESULTS: Doctors were more satisfied with EMR system than paper records, especially on editing (3.33 vs. 2.73, p<0.05) and retrieval (3.68 vs. 2.23, p<0.05). However, the degree of satisfaction was not significantly different from that of paper records in terms of input (3.22 vs. 3.03, p>0.05). Nurses were more satisfied with EMR system than paper records, e.g., editing (3.51 vs. 2.74, p<0.05), retrieval (4.07 vs. 2.51, p<0.05) and input (3.82 vs. 2.90, p<0.05). Also, doctors and nurses showed satisfaction for most of user interfaces. CONCLUSION: Users seem to be satisfied with the EMR system. EMR system should have a flexible system to improve the input system, the structured forms, and the standardized terminology according to the need of users.
