Purpose: The purpose of this study was to identify the effects of organizational justice, organizational culture and emotional intelligence on intention to stay in reemployed nurses. Methods: Data were collected from 154 reemployed nurses working in the two university hospitals located in G Province. Data were analyzed using t-test, ANOVA, Pearson’s Correlation Coefficient and Multiple Regression Analysis with SPSS/WIN 25.0. Results: Factors influencing intention to stay in the participants were period willing to stay (β=.36, p<.001), emotional intelligence (β=.35, p<.001), career break (β=.16, p=.015), organizational justice (β=.14, p=.046). The total explanatory power was 31%. Conclusion In this study, organizational justice, emotional intelligence, career interruption, period willing to stay were found to be influential factors affecting intention to stay in reemployed nurses. A systematic intervention program for emotional intelligence is needed to increase the intention of retention in reemployed nurses. Further, human resource managers and specialists should consider organizational justice when designing the talent retention strategies.

PURPOSE: The purpose of this study was to evaluate the proper axial thickness of zirconia abutment applied to implant in the anterior region. MATERIALS AND METHODS: Zirconia abutments were prepared at different axial wall thickness by processing pre-sintered zirconia blocks via CAD/CAM to obtain equal specimens. The abutments were each produced with a thickness of 0.5 mm (Group 1), 0.8 mm (Group 2), 1.2 mm (Group 3), or 1.5 mm (Group 4). The implant used in this study was a external connection type one (US, Osstem, Pussan, Korea) product and the zirconia abutment was prepared via replication of a cemented abutment. The crowns were prepared via CAM/CAM with a thickness of 1.5 mm and were cemented to the abutments using RelyX(TM) UniCem cement. A universal testing machine was used to apply load at 30 degrees and measure fracture strength of the zirconia abutment. RESULTS: Fracture strength of the abutments for Group 1, Group 2, Group 3, and Group 4 were 236.00 +/- 67.55 N, 599.00 +/- 15.80 N, 588.20 +/- 33.18 N, and 97.83 +/- 98.13 N, respectively. Group 1 showed a significantly lower value, as compared to the other groups (independent Mann-Whitney U-test. P<.05). No significant differences were detected among Group 2, Group 3, and Group 4 (independent Mann-Whitney U-test. P>.05). CONCLUSION: Zirconia abutment requires optimal thickness for fracture resistance. Within the limitation of this study, > 0.8 mm thickness is recommended for zirconia abutment in anterior implants.

Alopecia areata is a chronic organ-specific autoimmune disease and it could be associated with other autoimmune diseases. We, herein, report a case of alopecia areata in a patient with a thymoma without myasthenia gravis. Multiple hairless patches rapidly developed 6 weeks before the first visit on the patient who had been newly diagnosed with thymoma 2 weeks before the hairless patches occurred, and thymectomy was done 2 weeks before visiting dermatologic department. She had no symptoms associated with myasthenia gravis, and there were no abnormal findings on neurologic exams and acetylcholine receptor autoantibody was not detected in serum. Scalp biopsy showed numerous lymphocytic inflammations around hair follicles and in immunohistochemical staining, the aggregation of CD4+ and CD8+ T cells was observed around hair follicles and FoxP3+ T lymphocytes were rarely observed around hair follicles. The patient refused any treatment and her hairless patches were completely recovered 3 months after thymectomy, without being recurred 3 years after thymectomy. On the basis of both clinical manifestations and histologic findings, we concluded that alopecia areata in the patient had developed in association with thymoma and was recovered rapidly after thymectomy.

PURPOSE: The aim of this study was to analyze the shapes of lingual polished surfaces in lower complete dentures formed by polished surface impressions and to provide reference data for use when manufacturing edentulous trays and lower complete dentures. MATERIALS AND METHODS: Twenty-six patients with mandibular edentulism were studied. After lower wax dentures were fabricated, wax was removed from the lingual side of the wax denture and a lingual polished surface impression was obtained with tissue conditioner. The definitive denture was scanned with a three-dimensional scanner, and scanned images were obtained. At the cross-sections of the lingual frenum, lateral incisors, first premolars, first molars, and anterior border of the retromolar pads, three points were marked and eight measurements were taken. The Kruskal-Wallis test and a post hoc analysis with the Mann-Whitney test were performed. RESULTS: Each patient showed similar values for the same areas on the left and right sides without a statistically significant difference. The height of the contour of the lingual polished surface at the lingual frenum was halfway between the occlusal plane and lingual border, it moved gradually in a downward direction. The angle from the occlusal plane to the height of the contour of the lingual polished surface was increased as it progressed from the lingual frenum towards the retromolar pads. CONCLUSION: The shape of the mandibular lingual polished surface was convex at the lingual frenum, lateral incisors and gradually flattened towards the first molars and retromolar pads.

BACKGROUND: Chronic urticaria is defined as repeated episodes of wheals lasting for 6 weeks or longer. Nowadays, the role of vitamin D in various chronic diseases is a matter of great interest, but limited data is available on the vitamin D status in patients with chronic urticaria. OBJECTIVE: The goal of this study was to investigate the relationship between vitamin D status and clinical characteristics of chronic urticaria. METHODS: The clinical records of 72 patients with chronic urticaria, 26 with acute urticaria and 26 with atopic dermatitis, along with 72 healthy controls, were retrospectively reviewed. RESULTS: The serum 25-(OH)D3 level was found to be significantly reduced in patients with chronic urticaria compared to those in the other groups. In particular, the proportion of patients with critically low vitamin D levels (<10 ng/ml) was significantly higher in the chronic urticaria group than in the other groups. The serum vitamin D levels showed significant negative associations with urticaria activity score and disease duration. In addition, serum vitamin D levels were significantly lower in subjects with a positive autologous serum skin test than in subjects with a negative result. CONCLUSION: In conclusion, the serum vitamin D level was more likely to be critically low in patients with chronic urticaria, and an inverse relationship with disease severity and disease duration was observed. These findings may open up the possibility of the clinical use of vitamin D as a contributing factor in the pathogenesis of chronic urticaria and a predictive marker for disease activity in chronic urticaria.

OBJECTIVE: The aim of this study is to evaluate the clinical usefulness of cervicogram as primary screening test of cervical intraepithelial neoplasia. METHODS: Total 294 women who had undergone cervicogram and pathologically diagnosed at YUMC between January and July 2003, were selected. Diagnostic accuracy of Pap smear, cervicogram and Pap smear combined with cervicogram were compared with pathologic diagnosis. Statistical analysis was performed by chi-square test (SPSS version 11.0). RESULTS: 1. Among 294 women, Pap smears were normal in 130 cases (44.2%) and abnormal in 164 cases (55.8%). The diagnostic accuracy between Pap smear and histology was as follows; sensitivity 72.0%, specificity 64.6%, positive predictive value 72.0%, negative predictive value 64.6%, false positive rate 28.0%, false negative rate 35.4%. 2. Cervicogram were normal in 202 cases (68.7%) and abnormal in 92 cases (31.3%). The diagnostic accuracy between cervicogram and histology was as follows; sensitivity 39.6%, specificity 79.2%, positive predictive value 70.7%, negative predictive value 31.0%, false positive rate 29.3%, false negative rate 49.0%. 3. Among 130 women with normal Pap smear, cervicogram were normal in 101 cases (77.7%) and abnormal in 29 cases (22.3%). The diagnostic accuracy between cervicogram with normal Pap smear and histology was as follows; sensitivity 26.1%, specificity 79.8%, positive predictive value 41.4%, negative predictive value 66.3%, false positive rate 58.6%, false negative rate 33.7%. 4. Among 164 women with abnormal Pap smear, Cervicograms were normal in 101 cases (61.6%) and abnormal in 63 cases (38.4%). The diagnostic accuracy between cervicogram with abnormal Pap smear and histology was as follows; sensitivity 44.9%, specificity 78.3%, positive predictive value 84.1%, negative predictive value 32.7%, false positive rate 15.9%, false negative rate 67.3%. CONCLUSION: Although adjunctive use of cervicogram to Pap smear in initial screening of cervical intraepithelial neoplasia showed higher specificity, higher negative predictive value and lower false negative rate compared to Pap smear alone, but, consideration in terms of lower sensitivity, lower positive predictive value, higher false positive rate and cost-effectiveness should be given in lieu of clinically applicating cervicogram with Pap smear as initial screening test.
