Purpose: This study aimed to examine the levels of clinical decision-making ability, role conflict, and nursing work performance ability and to identify factors influencing nursing work performance ability among emergency room nurses. Methods: This study emploved a descriptive correlational research design. A total of 137 emergency room nurses, were participated. Data were collected at three tertiary hospitals located in city B, from June 1 to August 25, 2024. The collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Scheffé test, Pearson’s correlation, and multiple regression analysis using IBM SPSS 29.0 program. Results: The average score of clinical decision-making ability was 3.31, while role conflict and nursing work performance ability both had an average score of 3.77. Factors influencing nursing work performance ability included clinical decision-making ability, role conflict, and annual salary, which explained 20.0% of the variance in nursing work performance ability. Conclusion Clinical decision-making ability and role conflict significantly impact nursing work performance among emergency room nurses. Strategies to enhance clinical decision-making skills and mitigate role conflict should be developed at the organizational level. Additionally, further research is needed to on appropriate compensation systems and institutional measures to enhance nursing work performance.

This paper describes a community effort to improve earlier versions of the full-text corpus of Genomics & Informatics by semi-automatically detecting and correcting PDF-to-text conversion errors and optical character recognition errors during the first hackathon of Genomics & Informatics Annotation Hackathon (GIAH) event. Extracting text from multi-column biomedical documents such as Genomics & Informatics is known to be notoriously difficult. The hackathon was piloted as part of a coding competition of the ELTEC College of Engineering at Ewha Womans University in order to enable researchers and students to create or annotate their own versions of the Genomics & Informatics corpus, to gain and create knowledge about corpus linguistics, and simultaneously to acquire tangible and transferable skills. The proposed projects during the hackathon harness an internal database containing different versions of the corpus and annotations.

Purpose: To report a case of successful treatment of bilateral infectious keratitis combined with endophthalmitis caused by Pseudomonas aeruginosa in an immunocompromised patient.Case summary: A 66-year-old male with colon cancer and lung metastasis was referred to our clinic with ocular pain and reduced visual acuity in both eyes for 3 days. Visual acuity was “light perception” in both eyes at the first visit. On slit lamp examination, he presented with corneal central necrosis with mucopurulent discharge and anterior chamber hypopyon in both eyes. The left eye especially had vitreous haziness using a B-scan. Pseudomonas aeruginosa was detected in the corneal scrape culture and percutaneous transhepatic biliary drainage culture. After administration of topical eye drops, intravitreal injection, and systemic antibiotics, visual acuity improved from “light perception” to 20/63 in the right eye and to 20/125 in the left eye. Conclusions Although bilateral corneal ulcers combined with endophthalmitis induced by Pseudomonas aeruginosa are rare it can occur in immunocompromised patients. In the case of corneal ulcers combined with endophthalmitis, thorough ocular examinations and active treatments with intravitreal injections and systemic administration of antibiotics can help to recover vision.

PURPOSE: To compare the in vitro toxicity of commercial olopatadine anti-allergic ophthalmic agents on cultured rabbit's conjunctival cells according to concentrations and exposure times. METHODS: Rabbit conjunctival cells were exposed to anti-allergic olopatadine ophthalmic agents, (Patanol® [0.1% olopatadine hydrochloride; Alcon, Fort Worth, TX, USA], Pataday® [0.2% olopatadine hydrochloride; Alcon], and Pazeo® [0.7% olopatadine hydrochloride; Alcon]) at concentrations of 5%, 10%, and 15% for periods of 30 minutes, 1, 2, 3, and 6 hours, respectively. Cell proliferation and injury assays were performed using the methylthiazoltetrazolium and lactate dehydrogenase (LDH) leakage assays. We checked the composition of the three anti-allergic agents, and performed light and transmission electron microscopy to compare the morphological changes in cells. RESULTS: The conjunctival cell proliferation was inhibited after 1 hour exposure to each olopatadine ophthalmic agent, with significant cell proliferation inhibited using 15% of each drug. The proliferation of conjunctival cells was inhibited during 6 hours of drug exposure at all concentrations of Pataday® and Pazeo®. The titer of LDH increased from 3 hours after drug exposure, but 15% Pazeo® significantly increased the LDH titer at 2 hours after drug exposure. As the concentration of the drug increased, the LDH titer also significantly increased. The cellular morphological changes of conjunctival cells were in the increasing order of Pazeo®, Pataday®, and Patanol® with a high concentration of olopatadine hydrochloride. CONCLUSIONS Among the anti-allergic olopatidine ophthalmic agents, higher olopatadine concentrations in the increasing order of Pazeo®, Pataday®, and Patanol® resulted in cytoplasmic damage of conjunctival cells, but there was no severe damage to the cytoplasmic or the nuclear membranes.

PURPOSE: In the present study, the clinical characteristics and outcomes of neuroretinitis in Korea were investigated. METHODS: Seven consecutive patients with neuroretinitis from 2012 to 2015 were retrospectively reviewed. RESULTS: The present study included 9 eyes of 7 patients. The subjects consisted of 5 males and 2 females and the mean age was 45.1 ± 13.2 years. Two patients had Influenza-like symptoms and the others had no specific general symptoms. The mean best corrected visual acuity was logMAR 0.48 ± 0.55 (0-1.6) on the initial visit. Four patients 40 years of age or under had no abnormal findings in laboratory work-up. Conversely, 3 patients over 40 years of age were positive for Toxocara based on enzyme-linked immunosorbent assay (ELISA). Two of 3 patients positive for Toxocara were treated with albendazole and 1was not. Eight eyes had good visual recovery over 20/30 except for 1 patient who did not take the albendazole despite being positive for Toxocara detected using ELISA. CONCLUSIONS: Three of 7 patients with neuroretinitis in Korea showed positive results for Toxocara based on ELISA. In cases with seropositive Toxocara ELISA results, albendazole treatment should be considered.

PURPOSE: To assess the agreement and compare the performance of glaucoma diagnosis of peripapillary retinal nerve fiber layer (RNFL) thickness measurements between two different spectral-domain optical coherence tomography (SD-OCT) devices. METHODS: Eighty nine eyes of 56 patients with glaucoma and 42 eyes of 25 healthy individuals were imaged with Cirrus and Spectralis OCT in a single visit. Agreement between RNFL thickness measurements was assessed using intraclass coefficient (ICC) and Bland-Altman plots. The discriminating abilities of the two techniques for detection of glaucoma were compared by the area under the receiver operating characteristic curves (AUC) for quadrants and average RNFL thickness. RESULTS: ICC values for agreement between both instruments were good for quadrants and average RNFL thickness (all ≥ 0.81). However, Spectralis OCT measurements were significantly greater than Cirrus OCT for temporal quadrant (difference = 4.27 µm in normal group, 3.91 µm in glaucoma group, p < 0.001 for both). The RNFL thickness parameter with the largest AUCs was the average RNFL thickness for the Spectralis OCT and the Cirrus OCT (0.85 vs. 0.87, p = 0.30). The pair-wise comparison among the receiver operating characteristic curves showed no statistical difference for all parameters. CONCLUSIONS: Although Spectralis OCT measurements were significantly greater than Cirrus OCT for temporal quadrant, agreement of RNFL measurement between both the devices was generally good and there was no statistically significant difference in the performance of glaucoma diagnosis between both instruments.
