Purpose: This study is a pseudo-experimental study of design before and after the non-equivalent control group, which was attempted to verify that the application of the ukulele to the elderly has the effects of reducing depression, improving self-efficacy, strengthening social bonding, and improving cognitive function. Methods: 46 (23 in the experimental group and 23 in the control group) participants were selected. The experimental group was provided with three sessions of a music program using eight Ukuleles for the elderly, while the control group was provided with three sessions for the elderly. IBM SPSS 25.0 was used for data analysis, and the independent t-test, x2-test, and Fisher's exact probability test were performed to verify the homogeneity of the subject's general characteristics. The effect verification after the experimental treatment was analyzed by Fisher's exact probability test, Friedman test, and Mann-Whitney U test. Results: Depression showed a statistically significant difference between the two groups (F=39.88, p<.001), self-efficacy showed a statistically significant difference between the two groups (z=-4.96, p<.001), social bonding showed a statistically significant difference between the two groups (z=-5.19, p<.001), and cognitive function showed a statistically significant difference between the two groups (z=-3.98, p<.001). Conclusion: It was found that the ‘Music Program using the Ukulele’ was effective in reducing depression of the elderly, improving self-efficacy, reinforcing social bonding, and improving cognitive function. We hope that the Music Program using the Ukulele can be used in the elderly nursing curriculum in the future, and we suggest it should be applied as a nursing intervention to those who are experiencing cognitive decline.

Purpose: To evaluate the changes in injection frequency based on the diagnosis year in neovascular age-related macular degeneration (AMD) and the differences in visual outcomes associated with these changes. Methods: This retrospective study included 667 patients (667 eyes) diagnosed with treatment-naïve neovascular AMD and polypoidal choroidal vasculopathy in 2013, 2015, 2017, and 2019. The number of anti-vascular endothelial growth factor (VEGF) injections and degree of changes in visual acuity during the first 24 months after diagnosis were compared among the 4 years. Results: The 2013, 2015, 2017, and 2019 groups had a mean of 5.7 ± 2.7, 6.0 ± 2.8, 6.6 ± 3.0, and 6.9 ± 3.3 anti-VEGF injections, respectively. The number of injections was significantly higher in 2019 than in 2013 and 2015 (p < 0.001). The mean degree of visual change during the 24-month follow-up period was 0.07 ± 0.55, 0.01 ± 0.51, 0.08 ± 0.50, and 0.04 ± 0.48 in 2013, 2015, 2017, and 2019, respectively. There was a significant difference in the degree of visual change among the four groups (p = 0.020). Conclusions: Patients diagnosed more recently tend to receive more injections and have better visual outcomes. We speculate that more injections contributed to these results. This trend should be considered when predicting the future socioeconomic burden of neovascular AMD. 목적: 습성 나이관련황반변성에서 진단연도에 따른 주사 빈도의 변화를 확인하고 이러한 변화에 따른 시력 결과의 차이를 추가적으로분석하고자 한다. 대상과 방법: 2013년(2013군), 2015년(2015군), 2017년(2017군) 및 2019년(2019군)에 습성 나이관련황반변성과 결절맥락막혈관병증으로 진단된 667명(667안)의 환자를 대상으로 후향적 의무기록 분석을 시행하였다. 진단 후 24개월 동안의 항혈관내피성장인자 주사횟수와 시력 변화를 네 군 사이에 서로 비교하였다. 결과: 평균 주사 횟수는 2013군에서 5.7 ± 2.7회, 2015군에서 6.0 ± 2.8회, 2017군에서 6.6 ± 3.0회, 2019군에서 6.9 ± 3.3회였다. 2013군 및 2015군과 비교하였을 때 2019군에서의 주사 횟수는 유의하게 더 높았다(p<0.001). 동일 기간 동안의 시력 변화의 경우2013군에서는 평균 logarithm of minimal angle of resolution (logMAR) 0.07 ± 0.55 악화, 2015군의 경우 평균 0.01 ± 0.51 악화, 2017군의 경우 평균 0.08 ± 0.50 호전, 2019군의 경우 평균 0.04 ± 0.48 호전되었다. 네 군 사이에 시력 변화에는 유의한 차이가있었다(p=0.020). 결론: 보다 최근에 진단된 환자일수록 더 높은 빈도로 주사를 시행받은 경향이 확인되었고, 더 나은 시력 결과를 보였는데, 보다 적극적인 주사가 시력 결과에 영향을 미쳤을 것으로 추측된다. 향후 습성 나이관련황반변성에 대한 사회경제적 부담을 예측할 때 이러한경향이 고려되어야 할 것이다.

This study is a descriptive research study to confirm the care efficacy and empathy competency ofnursing hospital nurses and analyze the factors to improve person-centered care behavior, provide theoretical andpractical information accordingly, and prepare basic data. The study collected data from March 20, 2023 toApril 20, 2023, targeting 146 nurses at a nursing hospital for the elderly in C region located in G province,and finally analyzed a total of 144 copies. Using IBM SPSS/25, descriptive statistics t-test, ANOVA, andcorrelation multiple regression analysis were analyzed. As a result of analyzing the variables that affect thesubject's person-centered care by hierarchical multiple regression, the higher the caring efficacy and empathycapacity, the more the person-centered care was affected, and the explanatory power was 31.5%. As a result ofthis study, empathy competency and care efficacy were found to have an effect on person-centered care. It isthought that various measures should be prepared to improve the care efficacy and empathy competency for theefficient nursing performance of person-centered care of nursing hospital nurses.

Purpose: To evaluate long-term visual prognosis and changes in the retinal microstructure in patients with macular telangiectasia type 2. Methods: Retrospective analysis of medical records were performed for 61 eyes (32 patients) diagnosed with macular telangiectasia type 2. The visual acuity at diagnosis was compared with that at the final visit. In addition, cases were classified into three grades based on optical coherence tomography (OCT) findings: grade 1, inner retinal cavities only; grade 2, outer retinal cavities with ellipsoid zone disruption; and grade 3, ellipsoid zone disruption with proliferation of retinal pigment epithelium. Change in the grade during the follow-up was verified. In addition, visual acuities were compared between eyes with and without a change in grade. Results: The mean follow-up period was 41.5 ± 33.2 months. Visual acuity had deteriorated significantly from the mean logarithm of the minimal angle of resolution 0.23 ± 0.26 at diagnosis to a mean of 0.31 ± 0.31 at the final visit (p < 0.001). When classified using OCT, 65.6%, 22.9%, and 11.5% were grades 1, 2, and 3, respectively, at diagnosis and 47.5%, 36.1%, and 16.4% at the final visit. Progression of grade was noted in 22.9%. A higher degree of visual deterioration was noted in eyes showing progression than in eyes without (p = 0.002). Conclusions: During the long-term follow-up period, visual deterioration was noted in patients with macular telangiectasia type 2. However, the degree of deterioration was not high. Progression in the disruption of the retinal microstructure was the likely cause of visual deterioration. 목적: 제2형 황반부 모세혈관 확장증 환자들의 장기 시력예후 및 망막 미세구조의 변화에 대해 분석하고자 한다. 대상과 방법: 제2형 황반부 모세혈관 확장증으로 진단된 61안(32명)을 대상으로 후향적 의무기록 분석을 시행하였다. 최초 진단 시 시력을 최종 추적 관찰 시의 시력과 비교하였다. 추가적으로 빛간섭단층촬영 결과를 바탕으로 아래와 같이 세 군으로 분류하였다: 1단계=내망막 공동만 관찰된 경우, 2단계=외망막 공동, 타원체구역 손상이 관찰된 경우, 3단계=타원체구역 손상과 망막색소상피 증식이 관찰된 경우. 추적 관찰 기간 동안 단계의 변화를 확인하였으며, 단계 변화를 보인 안과 그렇지 않은 안 사이의 시력 변화 정도를 서로 비교하였다. 결과: 평균 경과 관찰 기간은 41.5 ± 33.2개월이었다. 시력은 진단 시 logarithm of minimal angle of resolution 평균 0.23 ± 0.26에서 최종 추적 관찰 시 평균 0.31 ± 0.31로 유의하게 악화되었다(p<0.001). 빛간섭단층촬영상 단계는 진단 시 65.6%에서 1단계, 22.9%에서 2단계, 11.5%에서 3단계로 분류되었으며, 최종 추적 관찰 시에는 각각 47.5%, 36.1%, 16.4%로 분류되었다. 전체의 22.9%에서 단계의 진행이 나타났으며, 진행을 보인 안은 그렇지 않은 안보다 큰 폭의 시력악화를 보였다(p=0.002). 결론: 제2형 황반부 모세혈관 확장증 환자에서는 지속적인 시력악화가 나타났으나 장기간의 경과 관찰에도 그 폭은 크지 않았다. 망막 미세구조 손상의 진행이 시력악화의 원인으로 생각된다.

남지인,제남주,강경혜,조경화,이성주,김민영,이민정 국제문화기술진흥원 2023 The Journal of the Convergence on Culture Technolo Vol.9 No.6

This study is a descriptive research study to analyze factors affecting patient safety management activities by identifying shared leadership, organizational communication, and nursing service perceived by nurses to prepare basic data for theoretical and practical information and intervention measures. This study collected data from 155 clinical nurses in C region in G-do from July 17 to July 28, 2023, and a total of 154 copies were finally analyzed. Using the SPSS Win. 25.0 program, technical statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical multiple regression were analyzed. As a result of analyzing variables affecting the subject's patient safety management activities with multiple regression using hierarchical selection, the higher the shared leadership, the higher the patient safety management. In order to efficiently perform nursing for nurses' patient safety management activities, research should be continuously conducted to develop specific intervention programs that can support patient safety nursing activities and verify their effectiveness
