  • After Landscape Act was enacted, as awareness of landscape has increased and the need of expanding targets of landscape design review and improving landscape examination in terms of quality, this study aims to describe a technique of creating three dimensional landscape simulation model which is used for landscape design review. For this, the author of this study conducted analysis in terms of function and use of programs and compatibility with programs to find a way of creating models with the most efficient and optimum process. For creation of landscape simulation models, initial creation is important but in case that changes occur by operator changing or discussing development plans, rapid correction and change are needed. Therefore, this study described how to build more accrurate and efficient simulation at initial review and how to create a landscape simulation model for rapid response to changed plans during reconsideration.

  • Objective: This study is a single-group pre-post experimental study to determine the effects of simulation-based practice education on nursing students' self-efficacy, performance confidence, and educational satisfaction. Design: Single-group pre-post experimental studies Methods: This study was conducted from September 1, 2023 to November 30, 2023 for nursing undergraduate students in a simulation based practical education program. The subjects were provided with learning materials about an acute myocardial infarction case with chest pain for preliminary learning. After that, they were divided into teams of 6 people and asked to do self-study for 2 hours per team, twice a week, before conducting simulation practice. For the simulation based practical education, the participants were divided into 9 teams of 6 people each, and each team had 10 minutes for orientation, 15 minutes for scenario operation, and 50 minutes for debriefing. Results: After the simulation based practical education, self-efficacy increased statistically significantly from a mean of 3.51 before training to a mean of 3.80 after training (t=-2.12, p=0.038). However, there was no significant difference in performance confidence. There was a significant positive correlation between self-efficacy and performance confidence (r=0.62, p<0.001) and training satisfaction (r=0.67, p<0.001) after the simulation based practical education. Self-confidence was also significantly correlated with educational satisfaction (r=0.76, p<0.001). Conclusions: The results of this study showed that utilizing simulation-based practical education can increase nursing students' self-efficacy, which positively affects their performance confidence and educational satisfaction. Therefore, simulation-based practical education is an effective nursing education method that can improve nursing students' practical skills.

  • Purpose: The purposes of this study were to identify nursing students' levels of anxiety in simulation based nursing education and to understand the relationship of anxiety and personal satisfaction of simulation, self-efficacy, and clinical competence during simulation. Methods: This study was a descriptive study with 84 senior nursing students at a private university in South Korea. Level of anxiety was measured with STAI (the State- Trait Anxiety Inventory) prior to the stimulation practice. After the debriefing, satisfaction scores were measured with SSE (Satisfaction with Simulation Experience scale), self-efficacy scores with the modified measurement developed by Roh and Park, and scores for clinical skills with a scale developed by the Korea Association of Cardiopulmonary Resuscitation. Results: Nursing students exhibited moderate to severe anxiety in simulation practice (Mean 49.51, SD 8.60). Self-efficacy was negatively correlated to anxiety (r=-.25, p=.022). Conclusion: Decreasing students' anxiety levels needs to be addressed to increase the self-efficacy of the simulation practice.

  • This study was a descriptive research investigating the impact of simulation-based learning on the problem solving process and clinical competence of new nurses. The 202 participants were new nurses who have provided nursing care for less than 12 months have experienced simulation-based learning more than once in their undergraduate courses. This study found that the number of times participants have experienced the simulation-based learning had no correlation with their problem solving process and clinical competence, but simulation design features correlated with their problem solving process and clinical competence. The results of clustering analysis that examined differences in the effects on problem solving process and clinical competence by classifying simulation design features by clustering also showed significant differences. This study has confirmed the importance of simulation design to simulation-based learning in nursing education. We hope that the findings of the study will be used for effective operation of simulation-based learning. In the future, objective assessment methods will be required to evaluate the effects of simulation-based learning provided in undergraduate courses on nurses' clinical competence.
