    Costing human performance has long been a goal in industrial and organizational psychology in evaluating the effects of organizational interventions on the benefits expressed in dollars. One procedure for estimating the utility of job performance has been developed by Schmidt, Hunter, McKenzie, and Muldrow (1979). The purpose of the present study was to investigate the applicability of the Schmidt-Hunter global estimation method to a broad range of jobs. The relationships between the applicability of the global estimation method and the Data, People, and Things parameters of work in the Dictionary of Occupational Titles (DOT) were investigated. The applicability of the method was evaluated by the distribution of dollar-valued job performance (the index of normality) and the degree of agreement in the utility estimates among raters (inter-rater reliability). Twenty-four independent jobs were selected from the DOT. Raters in this study were 95 members of the Society for Industrial and Organizational Psychology (SIOP). Questionnaires were mailed to them and they estimated the dollar values of all 24 jobs in this study. Contrary to the assumption of the global estimation method, the majority of jobs (62.5%) produced non-normal (positively skewed) distributions of dollar-valued job performance. It was found that the Data-People-Things codes can explain the applicability of the Schmidt et al.\u27s method across a variety of jobs. More importantly, the Data and People codes were highly related to the normality of dollar-valued performance distribution and the degree of agreement among raters. The more complex the job in the Data and People components, the more statistically non-normal (positively skewed) was the distribution of dollar-valued job performance. The more complex the job in the Data component, the more raters disagreed in their utility assessments. Therefore, it was concluded that the more complex the job in terms of the Data and People, the less applicable is the global estimation method. The convergence between the two methods of estimating SDy--the global estimation method and the 40% rule was discussed. The implications of these findings and suggestions for future research were also discussed

    Analysis of Content Legibility for Smartphones of Websites of the Korean Urological Association and Other Urological Societies in Korea

    Purpose: We performed an analysis of the smartphone legibility of the websites of the Korean Urological Association (KUA) and other urological societies. Materials and Methods: This study was conducted on the websites of the KUA and nine other urological societies. Each website was accessed via iPhone Safari and Android Chrome, respectively, to evaluate the establishment and readability of the mobile web pages. The provision of Really Simple Syndication (RSS) feeds by the websites and whether the websites had Twitter and Facebook accounts were evaluated. In addition, a validation test on the web standards was performed by using the World Wide Web Consortium (W3C???) Markup Validation Service, and subsequently the numbers of errors and warnings that occurred were analyzed. Results: When accessed via Safari, two websites were legible, four were somewhat legible, and four were somewhat illegible. When accessed via Chrome, two websites were legible, six were somewhat legible, and two were somewhat illegible. One website provided an RSS feed and two websites managed members via separate Twitter accounts. No website supported mobile web pages. The result of the W3C??? Markup Validation test on 10 websites showed a mean error rate of 221.6 (range, 13-1,477) and a mean warning rate of 127.13 (range, 0-655). Conclusions: The smartphone legibility level of the websites of urological societies was relatively low. Improved smartphone legibility and web standard compliance of the websites of urological societies are required to keep up with the popularity of smartphones

    Dysfunction in Configural Face Processing in Patients With Schizophrenia

    Background: Face recognition has important implications for patients with schizophrenia, who exhibit poor interpersonal and social skills. Previous reports have suggested that patients with schizophrenia have deficits in their ability to recognize faces, and because face recognition relies heavily on information about the configuration of faces, we hypothesized that patients with schizophrenia would have specific problems in processing configural information. Methods: We measured the performance of 20 patients with schizophrenia and 20 normal subjects in a face-discrimination task, using upright and inverted pairs of face photographs that differed in featural or configural information. Results: The patients with schizophrenia showed disproportionately poorer performance in discriminating configural compared with featural face sets. Conclusion: The result suggests that the face-recognition deficit in schizophrenic patients is due to specific impairments in configural processing of faces

    Efficacy of Central Neck Dissection for Clinically Node-Negative Papillary Thyroid Carcinoma: Propensity Scoring Matching

    Objectives: The utility of prophylactic central neck dissection (pCND) for papillary thyroid carcinoma (PTC) is still controversial. Although the procedure may reduce locoregional recurrence, it is associated with a high rate of postoperative complications. The aim of this study was to evaluate the role of pCND in patients with PTC.Materials and Methods: From January 1995 to April 2011, the records of 477 patients who underwent total thyroidectomy with or without pCND for clinically node-negative PTC measuring < 4 cm were retrospectively reviewed. Of these, 341 patients had undergone pCND with total thyroidectomy and 136 patients did not undergo pCND. The clinicopathologic characteristics, surgical outcomes, complications, recurrence, and survival were analyzed using propensity score matching, using age, sex, tumor size, extrathyroidal extension, and radioactive iodine ablation as covariates to minimize selection bias.Results: At baseline, there was no significant difference in sex, age, and multiplicity and bilaterality of the cancer between the two groups. However, extrathyroidal extension was more common and tumor size larger in patients who underwent pCND. For the propensity score-matched analysis, two matched groups, each comprising 135 patients, were generated. After propensity score matching, the significant differences observed at baseline between the two groups disappeared. The postoperative complication rate did not differ between the two groups. Recurrence occurred in 4 patients (2.96%) who had undergone pCND and in 2 patients (1.48%) who did not undergo pCND (P = 0.684). The recurrence-free survival curves did not differ between the two groups.Conclusion: The efficacy of pCND in total thyroidectomy for clinically node-negative PTC is limited, and pCND is not recommended for these patients

    Epidemiology and Assessment of Traumatic Spinal Cord Injury With Concomitant Brain Injury: An Observational Study in a Regional Trauma Center

    Objective To analyze the epidemiological information of patients with traumatic spinal cord injury (SCI) and concomitant traumatic brain injury (TBI) and to suggest points to be aware of during the initial physical examination of patients with SCI. Methods This study was a retrospective, observational study conducted in a regional trauma center. All the records of patients diagnosed with traumatic SCI between 2016 and 2020 were reviewed. A total of 627 patients with confirmed traumatic SCI were hospitalized. A retrospective study was conducted on 363 individuals. Results The epidemiological data of 363 individuals were investigated. Changes in American Spinal Injury Association Impairment Scale (AIS) scores in patients with SCI were evaluated. The initial evaluation was performed on average 11 days after the injury, and a follow-up examination was performed 43 days after. Fourteen of the 24 patients identified as having AIS A and SCI with concomitant TBI in the initial evaluation showed neurologic level of injury (NLI) recovery with AIS B or more. The conversion rate in patients with SCI and concomitant TBI exceeded that reported in previous studies in individuals with SCI. Conclusions Physical, cognitive, and emotional impairments caused by TBI present significant challenges in rehabilitating patients with SCI. In this study, the influence of concomitant TBI lesions could have caused the initial AIS assessment to be incorrect
