Background: Burnout negatively impacts the personal and professional life of nurses. Job stress and resilience have been determined to be associated with nurse burnout. Given the importance of communication competence in operating room (OR) nurses, the associations of job stress, resilience, and communication competence with burnout have not been examined. Purpose: To determine the relationships of job stress, resilience, and communication competence to burnout of OR nurses in South Korea. Methods: This was a cross-sectional, descriptive study of 146 OR nurses. A series of self-reported questionnaires was used to assess job stress, resilience, communication competence, and burnout. Pearson correlation coefficient and a hierarchical linear regression were used for data analysis. Results: Communication competence was correlated with resilience (r = 0.65, p < .001) and burnout (r = -0.44, p < .001), and resilience was correlated with burnout (r = -0.48, p < .001). Resilience (β = -0.22, p = .027) and communication competence (β = -0.33, p < .001) were associated with burnout of OR nurses in a hierarchical linear regression (F = 6.28, p < .001). Conclusions: Increased resilience and communication competence were associated with lower burnout of perioperative nurses. To prevent and reduce burnout of OR nurses, it is necessary to develop and implement a program targeting for communication competence and resilience. Implications for nursing management: Nurse leaders should provide programs fostering communication competence and resilience to OR nurses and encourage them to actively participate in such job trainings.

The study investigated whether neurofeedback training can normalize the excessive high-beta and low alpha waves indicative of hyperarousal, and subsequently improve autonomous regulation based on the self-determination theory in alcohol use disorders. A nonequivalent control group pretest-posttest design was used. Data were collected using self-report questionnaires from 36 Korean inpatients who met the Alcohol Use Disorder Identification Test in Korea criteria. Data were collected from quantitative electroencephalography to assess alpha (8-12 Hz) and high-beta (21-30 Hz) waves for hyperarousal. The questionnaires included Basic Psychological Need Satisfaction scales that assessed autonomy, competence, and relatedness, and the Alcohol Abstinence Self-Efficacy Scale and Treatment Self-Regulation Questionnaire. The experimental group underwent 10 sessions of neurofeedback training over four weeks. Data were analyzed using the chi-squared, Mann-Whitney U, and Wilcoxon signed-rank tests. In the experimental group, the alpha wave was increased in 15 of 19 sites and high-beta waves were decreased in 15 of 19 sites, but this difference was not significant. However, high-beta waves were increased in 15 of 19 sites in the control group, with seven sites (Fz, Cz, Pz, Fp2, F4, C4, and P4) showing significant increases. The experimental group showed a significant increase in basic psychological need satisfaction, alcohol abstinence self-efficacy, and self-regulation compared with the control group. Neurofeedback training is recommended for improving autonomous regulation in alcohol use disorder as a nursing intervention. However, for significantly attenuating hyperarousal through brain wave correction, it may be necessary to increase the number of neurofeedback sessions.

Recently, many topics in intelligent transportation system (ITS) are researched. One of the topics is adaptive cruise control (ACC). The adaptive cruise control systems should be designed such that string stability can be guaranteed in addition to that every vehicle in a string of ACC vehicles which use the same control law must track any bounded acceleration and velocity of its preceding vehicle with a bounded spacing and velocity error. The purpose of this paper is to design fuzzy logic based ACC which guarantees string stability. The feature of this controller is adaptation to a target speed and speed reduction to keep a safe distance from preceding vehicle and also guarantees string stability. This controller controls throttle angle and brake pressure. The performance of this controller has been investigated through computer simulation using Carsim of Mechanical Simulation Corporation. The results show that the proposed controller can guarantee safe time gap and string stability satisfactorily.
