Purpose: The purpose of this study was to evaluate the effects of Metaverse-based core nursing skill contents (CNSC) developed for undergraduate nursing students. Methods: A nonequivalent control group was sampled with a non-synchronized design. Seventy-two participants (experimental group 34, control group 38) were recruited from May to June 2022 in Gwangju metropolitan city. The CNSC consisted of scenarios of vital sign measurements, and subcutaneous injections (including blood sugar tests). The data were analyzed using SPSS version 25 for Windows. Results: At the completion of the CNSC, statistically differences were found between groups in knowledge of core nursing skills (t=6.20, p<.001), confidence in core nursing skills performance (t=5.71, p<.001), and clinical competency (t=3.32, p=.001). Conclusion These results indicate that the CNSC developed for undergraduate nursing students is effective in improving knowledge of core nursing skills, confidence in core nursing skills performance, and clinical competency for nursing students.

PURPOSE: This study aimed to investigate job satisfaction, organizational commitment and turnover intention among male nurses in South Korea. METHODS: Data were collected in May, 2013 and a total of 150 male hospital nurses participated in this study. Job satisfaction, organizational commitment and turnover intention were measured using a structured questionnaire. Collected data were analyzed using SPSS/WIN 20.0 for windows. RESULTS: There were statistically significant correlations between job satisfaction and organizational commitment (r=.74, p<.001), job satisfaction and turnover intention (r=-.56, p<.001), and organizational commitment and turnover intention (r=-.69, p< .001). There was a statistically significant difference in job satisfaction of participants according to education, work unit, and salary. Organizational commitment showed significant difference according to age, education, work unit, and salary. Turnover intention was significantly different according to duration of employment in the hospital, and salary. The most influential factor for turnover intention was organizational commitment (beta=-.69, p<.001). This factor accounted for 47.8% of the variance in turnover intention. CONCLUSION: The results of this study indicate that to reduce turnover intention for men in nursing, it is necessary to increase job satisfaction, and organizational commitment.

PURPOSE: To predict the accuracy of preoperative refractive error measurement methods in wavefront-guided laser-assisted subepithelial keratectomy (LASEK) surgery and to formulate a nomogram for satisfactory surgical results. METHODS: The medical records of 30 patients (57 eyes) who had undergone wavefront-guided LASEK were reviewed. The ideal surgical ablation amount was defined as the sum of the real surgical ablation amount and the remaining refractive errors. Comparison between the ideal surgical ablation amount and preoperative refractive errors was made using autorefraction, manifest refraction, cycloplegic refraction, postcycloplegic refraction, wavescan, and iTrace aberrometer measurements. RESULTS: The refractive errors measured by the postcycloplegic refraction showed the closest relation with the ideal surgical amount, and the nomogram based on this refraction correlated statistically significantly with the ideal surgical ablation amount. The refractive error using the wavescan also showed more accurate refractive measurements than the autorefractor and iTrace aberrometer. CONCLUSIONS: Accurate manifest refraction immediately before surgery is the most important in determining the ablation amount. Additionally, the refractive errors measured with the wavescan, which is an aberrometer used for wavefront-guided LASEK, showed a minimal amount of errors. After reviewing the results, the nomogram based on these 2 methods can be concluded to possibly contribute to an increase in the accuracy of surgery.

PURPOSE: To compare the anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) and refractive change after cataract surgery between 3-piece and 1-piece aspheric intraocular lens (IOL) implantation. METHODS: The present study consisted of 16 patients (25 eyes) having 3-piece aspheric Tecnis(R) ZA9003 IOL and 21 patients (30 eyes) having 1-piece aspheric Tecnis(R) ZCB00 IOL. The ACD, ACV, and ACA were measured using an anterior eye segment analysis system (Pentacam, Oculus, Wetzlar, Germany) preoperatively and postoperatively 1 week and 1 month. Refractive outcomes were evaluated using an autokeratometer. RESULTS: When comparing the 3-piece (Tecnis(R) ZA9003) and 1-piece (Tecnis(R) ZCB00) IOL with the same optic, ACD, ACV, and AVA increased significantly after cataract surgery. The 1-piece IOL showed deeper ACD than the 3-piece IOL at postoperative 1 week and 1 month. Postoperative refraction showed slight myopic shift compared with target diopter, but was stable in both groups. CONCLUSIONS: There was significant increase in ACD, ACV, and ACA after cataract surgery in both IOL-inserted groups. Results showed stable refraction after cataract surgery in both groups. Consideration of the A-constant will be needed because of myopic change with the 1-piece IOL.

PURPOSE: To compare the corneal measurements of Sirius and Pentacam in normal cornea and post-corneal refractive surgery patients. METHODS: Subjects were tested by Pentacam (OCULUS, Wetzlar, Germany), and Sirius (CSO, Firenze, Italy). Measurements included central corneal thickness, thinnest corneal thickness, anterior chamber depth, anterior chamber volume, iridocorneal angle, corneal volume, pupil size, and curvature of cornea. RESULTS: A total of 88 eyes from 44 patients were included in the present study. When comparing Sirius and Pentacam in the normal cornea, corneal thickness (p = 0.693), thinnest corneal thickness (p = 0.386), anterior chamber depth (p = 0.155), anterior chamber volume (p = 0.650), and pupil diameter (p = 0.124) did not differ significantly. Corneal curvature (p < 0.001), corneal volume (p = 0.023), and iridocorneal angle (p < 0.001) were statistically different. When comparing Sirius and Pentacam in post-corneal refractive surgery patients, corneal thickness (p = 0.056) did not differ significantly. There was a statistical difference in corneal curvature (p < 0.001), thinnest corneal thickness (p = 0.019), anterior chamber depth (p < 0.001), anterior chamber volume (p < 0.001), iridocorneal angle (p < 0.001), corneal volume (p < 0.001), and pupil diameter (p < 0.001). CONCLUSIONS: Anterior segment measurements with Pentacam and Sirius showed differences in post-corneal refractive surgery patients.

PURPOSE: To report a case of corneal ulcer due to Alcaligenes faecalis in a patient with a preexisting corneal ulcer. CASE SUMMARY: A 58-year-old male patient presented with a corneal ulcer without a history of any trauma. The patient had a history of corneal ulcer 9 months earlier. The patient had previously been diagnosed with diabetic retinopathy and neovascular glaucoma, and his visual acuity was no light perception. Corneal scraping and culture yielded Alcaligenes faecalis susceptible to most antibiotics in the antibiotic susceptibility test. After treatment with empirical systemic antibiotics and eyedrops, his eye improved with a remaining corneal scar. CONCLUSIONS: Alcaligenes faecalis should be considered as a causal pathogen of corneal ulcer in patients with suspicious compromised ocular surface, such as previous corneal ulcer.

PURPOSE: We investigated the correlations between optical quality parameters obtained from the double-pass system and ocular aberrations obtained from the ray-tracing aberrometer in multifocal intraocular lens (IOL) implanted eyes. MATERIALS AND METHODS: Twenty eyes from 20 patients were enrolled in this study. Modulation transfer function cutoff frequency, The Strehl ratio, objective scatter index, and objective pseudo-accommodation obtained from the double-pass system were compared with root mean square (RMS) total aberration, RMS higher-order aberration, and spherical aberration obtained from the ray-tracing aberrometer. Additionally, parameters of the double-pass system and ray-tracing aberrometer were compared with manifested refraction values and subjective visual acuity, respectively. RESULTS: There was no statistically significant correlation between optical quality parameters obtained from the double-pass system and ocular aberrations, except between the Strehl ratio and RMS total aberration (r=-0.566, p=0.018). No significant correlations were found between the parameters of both devices, and manifested refraction values or subjective visual acuity. CONCLUSION: Optical quality parameters, especially the Strehl ratio, in multifocal IOL implanted eyes were affected by RMS total aberration. Further studies based on accurate measurements of ocular aberrations and additional optical quality parameters are needed to delineate relationships between optical quality parameters and ocular aberrations in multifocal IOL implanted eyes.
