This study aimed to determine the effects of simulation learning program using SBAR (Situation, Background, Assessment, Recommendation) techniques on undergraduate nursing students' clinical judgment and communication skills. A quasi-experimental research design (one-group pretest-posttest design) was used in this study. The participants included 88 students from a nursing college. There were statistically significant differences in clinical judgment, communication clarity, and communication confidence between pre-simulation learning using SBAR and post (t=10.32, p<.0001; t=6.05, p=<.0001; t=7.42, p=<.0001). The simulation learning program using SBAR was found to improve nursing students' clinical judgment as well as clarity and confidence in interprofessional communication.

In this study, the system level network simulation is considered with adaptive array antenna in CDMA mobile communication system. A network simulation framework is implemented based on IS-95A/B system to consider dynamic handoff, system level network behavior, and deploying strategy into the overall CDMA mobile communication network under adaptive array algorithm. Its simulation model, such as vector channel model, adaptive beam forming antenna model, handoff model, and power control model, are described in detail with simulation block. In order to maximize SINR of received signal at antenna, maximin algorithm is particularly considered, and it is computed at each simulation snap shot with SINR based power control and handoff algorithm. Graphic user interface in this system level network simulator is also implemented to define the simulation environments and to represent simulation results on real mapping system. This paper also shows some features of simulation framework and simulation results.

Wargame simulators are widely used in the field of defence modeling and simulation. Because of increasing importance of communication effects on the warfare, the war game simulator is also required to reflect communication effects. One way to satisfy the requirement is the interoperation simulation between war game simulator and communication effect simulators. This paper shows the application of interoperation simulation between war game and communication effect simulators using HLA(High-Level Architecture)/RTI(RunTime Infrastructure). The war game simulator mainly deal with the engagement of troops and the troops communicate each other at the mission execution level. In the other hand, The communication effect simulator perform communication actions between the troops in the engineering level. Using the interoperation simulation, we can reflect the communication effects on the war game simulation. We show various applications of the interoperation simulation with the point of the war game and communication effect simulator. with a case study, we explain the interoperation simulation improves the reality and fidelity of the war game simulator and how the interoperation simulation can be applied to developing doctrines and real communication system.

Power line communication channels are very complicated and models for communication channels vary with the types of electrical equipment, devices and load fluctuations. So, modeling and analysis of power line channels for implementation of power line communication systems is a very important process. Power line channel modeling and simulation are performed based on power system transient simulation models and power system CAD tools to create precise and accurate models. In this paper, a channel modeling and simulation method is proposed for power line communication systems using PSCAD/EMTDC, in which a PN 63 sequence code generator is applied for impulse response of the power line channel in the simulation model.

Purpose: In this research, we develop an effectiveness analysis simulation model using Agent Based Modeling with Communication Effects for the development of a new weapon system. Methods: To describe the future battlefield that has more complexity, we develop Agent Based Modeling to describe communication Effects. We use the communication theory (Path-Loss Model) and the real map. Results: We have compared simulation model with real map and simulation model without real map. The Blue Survival Ratio of simulation model with real map is worse than one without real map since the performance of communication gets lower. Conclusion: There are many studies about the effectiveness analysis of a weapon system. Most of previous researches assumed no communication error. In the real world, however, it's not appropriate assumption. Therefore, this study considers the communication error and shows that it is important factor in the effectiveness analysis.

Purpose: This study was conducted to examine the effects of simulation-based education on communication skill and clinical competence in maternity nursing practicum. Methods: This study used a non-equivalent control pretest-posttest design. The simulation-based education in maternity nursing practicum consisted of two clinical situation scenarios pertaining to patients with normal and high-risk deliveries. The control group consisted of 35 students in 2010 and the experimental group consisted of 35 students in 2009. The experimental group was given the simulation-based education using a high-fidelity patient simulator over 3 sessions, whereas the control group was given a conventional pre-clinical practice orientation before maternity nursing clinical practicum. Data were collected using a questionnaire, which included questions to assess communication skill and clinical competence. Data were analyzed using SPSS/WIN 18.0. Results: Members of the experimental group, who received the simulation-based education, showed significantly higher communication skill and clinical competence scores than the control group (t=-2.39, p = .020; t=-2.71, p = .009). Conclusion: The simulation-based education in maternity nursing practicum is effective in promoting communication skill and clinical competence. With application of diverse clinical situation scenarios, it is recommended to develop and apply simulation-based education using a high-fidelity simulator in the area of maternity nursing.

Purpose: This study aimed to evaluate the effectiveness of simulation-based education on communication and clinical judgment in nursing students and nurses. Methods: A systematic review and meta-analysis were conducted in accordance with the PRISMA guidelines. Seven databases were searched to obtain articles published in Korean or English. Of 12,864 articles reviewed, 36 were included in a systematic review and 23 in a meta-analysis. To estimate the size of the effects of simulation-based education, a meta-analysis was performed using the R package meta program. The risk of bias was assessed using RoB 2.0 and ROBINS-I. Results: The effect sizes (ES) of simulation-based education on communication and clinical judgment were ES=0.77, 95% confidence interval (95% CI)=0.43 to 1.12 on communication-related variables and ES=1.84, 95% CI=1.03 to 2.65 on clinical judgment. Conclusion: Simulation-based education for nursing students and nurses is useful for improving their communication and clinical judgment. Thus, it is necessary to develop and apply simulation-based education programs for nursing students and nurses to improve their abilities in communications and clinical judgment.

Purpose: The purpose of the study was to investigate the relationships among self-leadership, communication and team efficacy of nursing students participating in integrated simulation training courses. Methods: Participants were 124 nursing students from the two different schools. Data were collected from December 2018 through January of 2019 and analyzed using t-test, ANOVA and Pearson's correlation coefficients. Results: Self-leadership, communication and team efficacy were significantly different according to satisfaction of major, satisfaction of simulation course and satisfaction of leadership. Also significant correlations were found among self-leadership, communication and team efficacy. Conclusion: The findings of this study indicate that education programs based on simulation courses should be developed to promote self-leadership, communication and team efficacy of nursing students. A diverse simulation curriculum to improve the practical skills of nursing students needs to be developed.
