The evaluation of construction technology services is to determine whether project performance for the contractor and the participating engineer as a construction manager. However, the contractor and the participant engineers have a difficult aspect due to the lack of preparation period and the other field movement of the participating engineers. The reason is that the evaluation period progresses at the completion time of the service. In this respect, this study attempts to extract the critical success factors in the evaluation. The method is to analyze the relative importance of each factor through the AHP analysis after extracting the factors through the in-depth interview with the experts. The above analyzed results will provide a work standard for the systematic implementation of construction management services.

Background: There is a high incidence of pain associated with an intravenous injection of propofol, and different methods have been used in an attempt to minimize the incidence and severity of this pain. This study compared the effect of a ketamine pretreatment with that of a remifentanil pretreatment on the pain associated with a propofol injection. Methods: 225 ASA physical status 1-2 adult patients scheduled for elective surgery were enrolled into this randomized double blind study. The patients received 2 ml of saline (n = 45), 2 ml of ketamine 20 mg (n = 45), 2 ml of remifentanil 0.01 mg (n = 45), or 2 ml of remifentanil 0.02 mg (n = 45) or 2 ml of remifentanil 0.03 mg (n = 45) 30 seconds prior to administering 2 mg/kg of 1% propofol. An anesthesiologist who was blinded to the study asked the patients to evaluate the pain using a four-point scale (none, mild, moderate, severe). Results: The remifentanil 0.02 mg, remifentanil 0.03 mg and ketamine groups showed significantly less frequent and intense pain than the saline group (P < 0.05). The remifentanil 0.02 mg and 0.03 mg provided as much pain relief as ketamine (P > 0.05), but the remifentanil 0.01 mg did not (P < 0.05). There was a similar incidence of injection pain in the remifentanil 0.02 mg and remifentanil 0.03 mg groups. Conclusions: An intravenous remifentanil 0.02 mg or remifentanil 0.03 mg pretreatment is as effective in alleviating the pain associated with a propofol injection as a intravenous ketamine pretreatment. The remifentanil 0.03 mg pretreatment had a similar analgesic effect relative to the remifentanil 0.02 mg pretreatment. (Korean J Anesthesiol 2006; 51: 302~7)
