This paper investigates the service quality determinants in management consulting. Quality dimensions in SERVQUAL research, as well as several dimensions specific to the consulting service, have been reviewed. A survey has been conducted by carefully developed questionnaires for the hypothesized eight quality dimensions. The results of the statistical analyses support the eight quality dimensions in the consulting service : reliability, assurance, responsiveness, empathy, ethics, participation, communication, and reputation. The results demonstrate that reliability, assurance, participation, and reputation are especially influential in determining customer satisfaction. The research results provide useful insights for a customer in assessing alternative service providers and foreseeing the outcome from the chosen consultants.

Background and Objectives: The aim of this study was to investigate the balloon occlusive diameter (BOD) of non-circular defects in the transcatheter closure of atrial septal defect (ASD). Subjects and Methods: A total of 67 patients who had undergone transcatheter closure of an ASD were reviewed retrospectively. A non-circular defect was defined as the ratio of the short diameter to the long diameter of the defect on the en-face image less than 0.75. The BOD was compared with the long diameter of the defect and then compared between the two groups. Results: There were 22 patients with circular defects and 45 patients with non-circular defects. The difference in BOD measuring from the long diameter of the defect was quite different between the two groups and significantly smaller in non-circular morphology (0.1 ±4.0 vs. 2.3±2.1, p=0.006). The difference in BOD measurement from the long diameter of ASD showed a positive correlation with the ratio of the short diameter to the long diameter of ASD (b/a) (r 2 =0.102, p=0.008). In the non-circular morphology of ASD, the difference in BOD mea-sured from the long diameter had a significant negative correlation with the long diameter of ASD (r 2 =0.230, p=0.001), whereas in circular ASD, no significant correlation was found between the difference in BOD and the long diameter of ASD (p=0.201). Conclusion: The BOD compared with the long diameter measured from three-dimensional transesophageal echocardiography was smaller in non-circular ASD than in circular ASD. This difference was much smaller in non-circular ASD with a large long diameter.
