Purpose: To develop a Korean version of the practice environment scale that can verify the practice environment of advanced practice registered nurses (APRN) by verifying the validity and reliability of the Nurse practitioner's primary care organizational climate questionnaire developed by Poghosyan et al. Methods: After translation using a committee approach and an expert group’s verification of the content validity, items were classified as 'professional visibility', 'APRN-administration relations', 'APRN-physician relations', 'independent practice and support' A total of 29 questionnaire items were developed for the four factors. Data were collected from 200 advanced practice registered nurses working at two advanced general hospitals and six general hospitals. Results: In the confirmatory factor analysis, CFI, TLI, and RMSR evaluation indices were appropriate except for RMSEA. Partial validity was shown in convergent validity, and discriminant validity. Exploratory factor analysis revealed that the questions were well organized with four factors. Cronbach's ⍺ of the whole instrument was .93. Conclusion As a first attempt to measure the practice environment of the APRN in Korea, the results show that this questionnaire provides basic data for correct role setting and improvement of practice environment. This research will ultimately serve as a basis for cost-effective quality care.

PURPOSE: To assess the accuracy of magnetic resonance(MR) arthrography in the diagnosis of anterior labral tear of the shoulder. MATERIALS AND METHODS: Between Semptember 1996 and February 2000, MR arthrography of the shoulder was performed in 281 patients with a history of shoulder pain or instability. Among this total, only 157 shoulders in 154 patients who underwent arthroscopy or open surgery 0 to 230 (average, 20.9) days after MR arthrography were included in this study; the subjects comprised of 150 males and 4 females with an average age of 23.3 years. MR arthrographs of these 154 patients were analyzed for the presence of anterior labral tears, and the findings were correlated with the arthroscopic and surgical findings. Anterior labral tear was classified as A to D according to its location, as determined by arthroscopy and surgery. (A=4 to 6 o 'clock direction, anteroinferior; B=2 to 4 o 'clock direction, central; C=12 to 2 o 'clock direction, anterosuperior; D= SLAP lesions). The retrospective analysis of MR arthrographs showing false-positive and negative findings was also undertaken. RESULTS: In the diagnosis of anterior labral tear, MR arthrography showed a sensitivity of 94%, a specificity of 90% and an accuracy of 91%. Anterior labral tears were confirmed by arthroscopy or surgery in 62 of the 157 shoulders (39%). Among 62 lesions, two (3%) were observed in area A, 32(52%) in area A+B, nine (15%) in area A+B+C, one(2%) in area A+B+D, 13(21%) in area A+B+C+D, two (3%) in area B+C, one(2%) in area B+D, and two(3%) in area C. Among ten false-positive cases, seven were focal lesions (two, three and two lesions in area A, B and C, respectively), and in the remaining three cases, located in area A+B, MR arthrography revealed thickening and deformation. All four false negatives were focal lesions (two in area A and two in area C). CONCLUSION: Other than in focal lesions, in which accuracy was relatively low, MR arthrography showed high sensitivity, specificity and accuracy in the diagnosis of anterior labral tear of the shoulder.
