Purpose: Clinical nurses are the ideal health care providers to advocate for vulnerable and underserved populations such as people with disability. This study aimed to understand factors influencing nursing advocacy for people with disability among clinical nurses. Methods: The subjects of this study were 186 clinical nurses who were working in three hospitals in B and D cities. Self-report questionnaires were used to collect the data. Data were analyzed using IBM SPSS Statistics 25 with descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. Results: Clinical experience and esthetical nursing competency have positive correlations with nursing advocacy, and optimism-human rights has a negative correlation with nursing advocacy. Factors influencing nursing advocacy for people with disability were identified as patient directivity (β=0.36, p=.001), optimism-human rights (β=-0.18, p=.008) and clinical experience (≥10) (β=0.14, p=.036). The final model consisting of these factors explained 19% of the variance of nursing advocacy (F=14.99, p=.001). Conclusion: The findings of this study indicate the importance of developing and implementing nursing interventions that can improve patient directivity and optimism-human rights toward people with disability among clinical nurses. These nursing advocacy interventions can be provided as part of continuing education as well as the nursing curriculum.

Purpose: This study examined the mediating effect of the individualism-collectivism tendency of hospital nurses on the impact of their generation on professional pride and organizational commitment. Methods: 163 nurses participated in the study. One-way analysis of variance (ANOVA) and SPSS' Process Macro Model 4 was used to examine the relationships. Results: No intergenerational differences in individualistic propensity were observed, while collectivist propensity was higher in X-generation than Z-generation. Further, X-generation showed higher professional pride and organizational commitment than Y- and Z-generation. Notably, collectivistic (individualistic) tendency had (did not have) a mediating effect on the influence of generation on professional pride and organizational commitment. Conclusion: This study provided empirical evidence on the antecedent factors for forming collectivistic organizational culture in nursing organizations by demonstrating the mediating effect of collectivism propensity on professional pride and organizational commitment according to hospital nurses' generations nurses.

Purpose: The purpose of this study was to determine the impacts of vocational calling, emotional intelligence, and major commitment on nursing college students' happiness. This study also was conducted to explore major commitment's mediating effect on the relationship between vocational calling, emotional intelligence, and major commitment among nursing college students. Methods: Participants were 346 nursing college students. Data were collected in November, 2017 with self-report questionnaires and were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficients, and regression analysis with IBM SPSS 19.0. Results: The regression model explained 33.0% of variance in nursing college students' happiness (F=41.44, p<.001). Significant factors were emotional intelligence (${\beta}=.30$, p<.001), grade (${\beta}=.20$, p<.001), major commitment (${\beta}=.18$, p=.002), and vocational calling (${\beta}=.11$, p=.035). Moreover, major commitment showed partial mediating effects on vocational calling and happiness. Major commitment also showed partial mediating effects on emotional intelligence and happiness. Conclusion: The results suggest that nursing college students' happiness can be increased through strategies aimed at increasing vocational calling, emotional intelligence, and major commitment.

Purpose: The present study was designed to compare the incidence of periodontitis according to menopausal status and to investigate the possible effect of hormone replacement therapy (HRT) on periodontitis in postmenopausal women using a common data model (CDM) at a single institution. Methods: This study involved retrospective cohort data of 950,751 patients from a 20-year database (2001 to 2020) of Ewha Womans University Mokdong Hospital converted to the Observational Medical Outcomes Partnership CDM. One-way analysis of variance models and the χ² test were used to analyze the statistical differences in patient characteristics among groups. A time-dependent Cox regression analysis was used to calculate hazard ratios and 95% confidence intervals, and P values less than 0.05 were considered to indicate statistical significance. Results: Of the 29,729 patients, 1,307 patients were diagnosed with periodontitis and 28,422 patients were not. Periodontitis was significantly more common among postmenopausal patients regardless of HRT status than among the non-menopausal group (P<0.05). Time-dependent Cox regression analysis showed that the postmenopausal patients had a significantly higher chance of having periodontitis than non-menopausal patients (P<0.05), but after adjustment for age, body mass index, and smoking status, the difference between the non-menopausal and post-menopausal HRT-treated groups was insignificant (P=0.140). Conclusions: Postmenopausal women had a significantly greater risk of periodontitis than non-menopausal women. Additionally, the use of HRT in postmenopausal women could reduce the incidence of periodontitis.

Purpose: The study was performed to identify the process of change, decisional balance and self-efficacy corresponding to the stage of exercise behavior change based on a Transtheoretical Model in middle aged women. Method: The subjects consisted of 317 women by convenience sampling residing in city B. The collected data were analyzed using one-way ANOVA, Scheffe test, and Discriminant analysis by SPSS/WIN program. Result: The subjects were distributed in each stage of change of exercise behaviors: 53 subjects (16.7%) in the precontemplation stage, 86 subjects (27.1%) in the contemplation stage, 88 subjects (27.8%) in the preparation stage, 51 subjects (16.1%) in the action stage and 39 subjects(12.3%) in the maintenance stage. Analysis of variance showed that consciousness raising (F=24.96, p=.00), environmental reevaluation (F=7.l3, p=.00), self reevaluation (F=19.47, p=.00), dramatic relief (F=15.22, p=.00), social liberation (F=4.26, p=.00), counter conditioning (F=26.44, p=.00), a helping relationship (F=13.l7, p=.00), reinforcement management (F=21.25, p=.00), self liberation (F=27.70, p=.00), stimulus control (F=13.49, p=.00), pros (F=14.40, p=.00) and self-efficacy (F=39.9l, p=.00) were significantly associated with the stages of change of exercise behaviors. Through discriminant analysis, it was found that ‘stimulus control’ was the most influential variable in discriminating the five stages of change. Conclusion: This study can provide the basis of a staged matching exercise program using TTM for more effective and useful intervention.

Purpose: To identify factors influencing health-related quality of life for young single-person households, this study investigated physical and mental health status, health behavior, depression, resilience, and health-related quality of life. Methods: An online survey was administered to members of young single-person households from March 22 to 30, 2022. The data were analyzed using the chi-square test, independent t-test, one-way analysis of variance, Pearson correlation coefficients, multiple regression, and a simple mediation model applying the PROCESS macro model 4 with 95% bias-corrected bootstrapped confidence intervals. Results: The participants were 229 members of young single-person households. Health-related quality of life showed significant relationships with residence (t = 2.80, p = .006), month (F = 3.70, p = .026), mental health status (F = 20.33, p < . 001), and high-intensity exercise (F = 7.35, p = .001) among general and health-related characteristics. Health-related quality of life had significant correlations with depression (r = -.72, p < .001) and resilience (r = .58, p < .001). Multiple regression analysis showed that depression (β = -.57, p < .001) and resilience (β = .21, p < .001) influenced health-related quality of life. Moreover, resilience had a mediating effect between depression and health-related quality of life (indirect effect = -0.002, 95% bias-corrected bootstrapped confidence interval = -0.003 to -0.001). Conclusion: Members of young single-person households tended to be more vulnerable to emergency situations, such as during the coronavirus disease 2019 pandemic, when lockdowns and quarantines were frequent. To improve health-related quality of life in young single-person households, people with high levels of depression or low levels of resilience need special attention and support to promote mental health.

Statement of problem. In distal extension removable partial denture, the preservation of health of abutment teeth is very important, but abutment teeth are subjected to unfavorable stress. Purpose. The purpose of this study was to investigate the biomechanical effects of mandibular removable partial dentures with various prosthetic designs using strain gauge analysis. Material and methods. Artificial teeth of both canines were anchored bilaterally in a mandibular edentulous model made of resin. Bilateral distal extension removable partial dentures with splinted and unsplinted abutments were fabricated. Group 1 : Clasp-retained mandibular removable partial denture with unsplinted abuhnents Group 2 : Clasp-retained mandibular removable partial denture with splinted abutments by 6-unit bridge Group 3 : Bar-retained mandibular removable partial denture Strain gauges were bonded on the labial plate of the mandibular resin model, approximately 2 mm close to the abutments. Two vertical experimental loadings (100N and 200N) were applied subsequently via two miniature load cells that were placed at mandibular first molar regions. Strain measurements were performed and simultaneously monitored from a computer connected to data acquisition system. For within-group evaluations, t-test was used to compare the strain values and for between-group comparisons, a one-way analysis of variance (ANOVA) was used and Duncan test was used as post hoc comparisons. Results. Strain values increased as the applied load increased from 100N to 200N for all groups (p<.05). The strain values of group 1 and 2 were tensile under loadings. In contrast, strain values of group 3 were compressive in nature. Under 100N loading, group 1 showed higher strain values than group 3 in absolute quantity (p<.05). Under 200N loading, group 3 showed higher strain values than group 1 and 2 in absolute quantity (p<.05). Group 1 showed higher strain values than group 2 (p<.05). Conclusion. Splinting of two isolated abutments by bridge reduced the peri-abutment strain in comparison with unsplinted abutments. Strain of bar-retained removable partial denture increased much more as applied load increased, but was compressive in nature.

Background Pain in the postoperative body contouring patient has traditionally been managed with narcotic medication. In an effort to minimize side effects and prevent addiction, plastic surgeons are searching for novel ways to provide adequate analgesia, one of which is nerve blocks. This study was conducted with a meta-analysis that evaluates the efficacy of these blocks for patients who undergo breast surgery. Methods A search of the PubMed/MEDLINE database for articles including the terms "post-operative analgesia" OR "postoperative pain management" AND "in plastic surgery" OR "in cosmetic surgery" OR "in elective surgery" in February 2019 generated five studies on elective breast augmentation and reduction mammoplasty that reported pain scores and quantities of opioids consumed. Independent samples t-tests, one-way analysis of variance, and a random effects model were implemented for evaluation. Results A total of 317 patients were identified as having undergone body contouring of the breast, about half of which received a nerve block. Pain scores on a 1-10 scale and opioid dose-equivalents were calculated. Those who were blocked had an average score of 2.40 compared to 3.64 for those who did not (P<0.001), and required an average of 5.20 less narcotic doses (P<0.001). Pain relief following subpectoral augmentation was best achieved with type-II blocks as opposed to type-I and type-II with serratus plane (P<0.001). Conclusions The opioid epidemic has extended to all surgical specialties. Implementation of a nerve block seems to be an efficacious and cost-effective mechanism to not only help with post-operative pain, but also lower the need for narcotics, especially in subpectoral augmentation.

PURPOSE. The purpose of this study was to analyze the marginal fit of three-unit resin prostheses printed with the stereolithography (SLA) method in two build orientations (45°, 60°) and two layer thicknesses (50 ㎛, 100 ㎛). MATERIALS AND METHODS. A master model for a three-unit resin prosthesis was designed with two implant abutments. Forty specimens were printed using an SLA 3D printer. The specimens were printed with two build orientations (45°, 60°), and each orientation was printed with two layer thicknesses (50 ㎛, 100 ㎛). The marginal fit was measured as the marginal gap (MG) and absolute marginal discrepancy (AMD), and MG and AMD measurements were performed at 8 points per abutment, for 16 points per specimen. All statistical analyses were performed using SPSS software. Two-way analysis of variance (ANOVA) was separately performed on the MG and AMD values of the build orientations and layer thicknesses. Moreover, one-way ANOVA was performed for each point within each group. RESULTS. The margins of the area adjacent to the pontic showed significantly high values, and the values were smaller when the build orientation was 45° than when it was 60°. However, the margin did not differ significantly according to the layer thicknesses. CONCLUSION. The marginal fit of the three-unit resin prosthesis fabricated by the SLA 3D method was affected by the pontic. Moreover, the marginal fit was affected by the build orientation. The 45° build orientation is recommended.

The purpose of this study was to analyze the structural relationship between job satisfaction levels felt during ultrasound examination of radiological technologists (RTs) using a structural equation model. The subjects were a total of 203 RTs currently working in medical institutions. The method was conducted as a survey study using a questionnaire consisting of a total of 29 questions consisting of demographic characteristics and job satisfaction levels that were self-efficacy, job competency, extrinsic compensation, and job satisfaction. The reliability was secured with the Cronbach's alpha coefficient of 0.6 or higher. For statistical analysis, a significant difference between the frequency analysis of demographic characteristics and the mean of the job satisfaction levels were performed by independent sample T-test and one-way analysis of variance (ANOVA) followed by Scheffe's post hoc test. The correlation analysis between variables was tested with Spearman's and Pearson's correlation coefficient. We analyzed the structural relationships between variables by structural equations. As a result, first, job competency and extrinsic compensation had a positive effect on job satisfaction on ultrasound examination of RTs. Second, the self-efficacy of ultrasound examination RTs showed a high correlation with job competency. Third, the job satisfaction levels showed in the order of job competency, job satisfaction, self-efficacy, and extrinsic compensation. In conclusion, this study are expected to be provided as data to identify factors that could improve job satisfaction during ultrasound examination of RTs by empirically analyzing the structural relationship of self-efficacy, job competency, and external compensation.
