Purpose: This study aimed to identify the relationship between the experiences of workplace violence and post-traumatic stress disorder and the moderating effect of resilience and social support at work on the relationship in tertiary hospital nurses. Methods: This was a descriptive correlation study to confirm the moderating effect of resilience and social support at work on the factors affecting post-traumatic stress disorder for nurses who have experienced violence. A total of 146 registered nurses were recruited from a tertiary hospital from March to July 2020. The Participants who worked for more than one year and experienced violence at work completed self-reported questionnaires that measured the experiences of workplace violence and post-traumatic stress disorder, resilience, social support at work, and demographic information. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression analysis. Results: The nurses experienced verbal abuse an average of 3.70±2.06 times a week, physical threat an average of 2.30±1.71 times a month, and physical assault an average of 0.76±0.82 times a year. The Experiences of workplace violence were significantly increased post-traumatic stress disorder. The result also showed that resilience moderated the relationship between the experience of verbal abuse and post-traumatic stress disorder in hospital nurses. However, there was no significant moderating effect of social support between workplace violence and post-traumatic stress disorder. Conclusion: The experiences of workplace violence influenced post-traumatic stress disorder in nurses and were moderated by resilience. Therefore, hospital administrators need to develop and provide a workplace violence prevention and resilience reinforcement program to reduce post-traumatic stress disorder in nurses. In addition, we suggest further research on the effect of social support in a workplace on the experiences of violence.

For the composite section of corrugated steel sheet and concrete, which is often used in soil structures, a conservative design method based on the ultimate strength state is still applied due to the difficulty of the analysis of compatibility condition. In this study, plastic analysis was performed on the flexural and axial strength of the composite section using two limit state design methods, LRFD and LSD. As a result of the analysis of the experimental results, the LRFD analysis value was interpreted as a conservative results for compressive strength, and it was analyzed that the effect of the concrete compressive strength was greater than the steel ratio of the steel plate. The flexural strength was analyzed to be in good agreement with the experimental results by the LSD analysis. From the parametric analysis on the design variables, the hogging moment, which is affected by the tensile strength of the steel plate, slightly decreased the increasing rate of the strength due to the influence of the bolts connection, but the sagging moment linearly increased according to the increment of steel reinforcement ratio.

Purpose : The study was to promote patient safety by analyzing the effect of dental hygienist's perception of patient safety culture on infection control activities. Methods : The study is based on a survey of 210 dental hygienists in total working in dental settings. To find out infection control activities according to patient safety culture awareness, there were 6 general characteristics, 3 teamwork within the department, 2 infection control systems, 4 surface management, 9 equipment washing, disinfection, and laundry management, 4 infectious wastes, and 3 personal protection phrases.The data was analyzed using the SPSS version 20.0, and p<.05 was adopted to decide on significance. Results : The longer dental hygienists have worked n the dental settings, the more active they become in infection control activities. Among the different types of dental care settings, general (university) hospitals had the largest number of infection control activities, followed by dental clinics, and network dental clinics, in descending order. The dental settings possessing a higher number of dental hygienists were found to conduct more infection control activities than other dental settings. In addition, it was found that when a dental setting adopts a patient safety policy across all the units in the hospital, more systems and procedures for patient safety tend to be established, and that stricter management response to error leads to improvement of infection control activities. Conclusion :In order to enhance infection control activities, infection control activity programs should develop and implement periodic reinforcement of infection control education. regular monitoring of infection control activities.

This study compares the revised method in loose saturated sandy ground where the LNG storage tank will be installed with an evaluation method by one-dimensional effective stress analysis using the UBC3D-PLM model. Various laboratory and field tests were conducted to establish the parameters necessary for evaluation. The revised liquefaction evaluation method using the seismic response analysis result and N value from standard penetration testing evaluated the possibility of liquefaction as high, but assessment using effective stress analysis, which can consider various liquefaction resistance factors, found the site to be somewhat stable against liquefaction. One-dimensional finite element analysis using UBC3D-PLM modeling facilitated easier assessment of stability against liquefaction than the other methods and minimized the area required for reinforcement against liquefaction. In addition, it is expected that two-and three-dimensional numerical analysis considering the foundation of the LNG storage tank can identify the seismic design and behavior when liquefaction occurs.

Purpose: This study reports on a series of patients with chronic lateral ankle instability that underwent the Brostrom procedure with suture tape augmentation and allowed early unrestricted weight-bearing in a simple stirrup brace. Materials and Methods: This retrospective study was conducted on 36 patients (22 males and 14 females of mean age 34 years [range 23~48 years]) with chronic lateral ankle instability treated using the Brostrom procedure using suture tape augmentation and inferior extensor retinaculum reinforcement with a fiber-wire connected to a SwiveLock screw inserted into the talus. When possible, patients started unrestricted weight-bearing in a stirrup brace from the third postoperative day. Demographics and functional outcomes, including American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot, visual analogue scale (VAS), and satisfaction scores, were recorded. In addition, varus stress radiographs obtained before and 24 months after surgery were compared. Patients were followed for a mean 29 months (range 25~40 months). Results: Mean AOFAS ankle-hindfoot scores increased from 51 points preoperatively to 92 points at final follow-up, and mean VAS decreased from 6.8 to 1.2 points. Mean patient satisfaction scores were 8.7 at 12 months and 9.6 at 24 months. Stress radiographs demonstrated that talar tilt decreased from a mean 18 degrees preoperatively to 7 degrees at 24 months. Conclusion: Early unrestricted weight-bearing in a stirrup brace following the Brostrom procedure with suture tape augmentation is a successful protocol for treating chronic lateral ankle instability.

Purpose: This study attempted to present a strategy to increase behavioral vaccination intention by identifying factors affecting parents' intention to have their children vaccinated against coronavirus disease 2019 (COVID-19) by applying the modified theory of planned behavior. Methods: An online survey was conducted with 146 parents of children aged 5 to 17 from August 1 to 30, 2022, and, as a result, 146 data were analyzed. The moderating effect of perceived behavioral control in the relationship between parents' attitude, subjective norms, and behavioral intention for children's COVID-19 vaccination was analyzed using the Process Macro (10,000 bootstrapping, 95% confidence interval), and a simple slope analysis was performed to identify differences by group. Results: The moderating effect of perceived behavioral control was statistically significant in the relationship between parent's attitude and subjective norms for COVID-19 vaccination and behavioral intention. In the simple slope analysis, the reinforcement effect was greatest when the level of perceived behavioral control was high. Conclusion: Since vaccination is most likely when recommended by healthcare providers, it is necessary to ensure that health education through community health experts or mass media can be effectively conducted. In particular, objective information on the effectiveness and safety of COVID-19 vaccinations for children, including monitoring of potential side-effects, should be actively reported.

This paper presents a new approach of risk evaluation method for the reinforced slopes. In order to perform this study, the existing stability and risk evaluation methods are reviewed and analysed in terms of rainfall, ground condition, and drain conditions. According to the characteristic of the reinforced slopes improved by internal and external reinforcement, the nineteen influence factors are determined in order to develop new risk analysis model based on 'Interaction matrix' approach suggested by Hudson (1991). Using new approach of slope risk analysis model, the weighting values for interaction factors are analysed and determined. Based on new slope risk evaluation approach, the slope risk index, namely SRI (Slope Risk Index) is developed in this study to apply the evaluation of the reinforced slopes. In order to verify the SRI, a total of 15 cases are studied and analysed. The analysed results are compared and evaluated. According to the results, it is deduced that new slope risk evaluation method (SRI approach) IS very useful and practically a reliable method to evaluate the existing slopes.
