Purpose The purpose of this study was to examine the effects of a virtual reality simulation and a blended simulation on nursing care for children with asthma through an evaluation of critical ...thinking, problem-solving processes, and clinical performance in both education groups before and after the educational intervention. Methods The participants were 48 nursing students. The experimental group (n=22) received a blended simulation, combining a virtual reality simulation and a high-fidelity simulation, while the control group (n=26) received only a virtual reality simulation. Data were collected from February 25 to 28, 2019 and analyzed using SPSS version 25 for Windows. Results The pretest and posttest results of each group showed statistically significant improvements in critical thinking, problem-solving processes, and clinical performance. In a comparison of the results of the two education groups, the only statistically significant difference was found for critical thinking. Conclusion Simulation-based education in child nursing has continued to involve high-fidelity simulations that are currently run in many programs. However, incorporating a new type of blended simulation, combining a virtual reality simulation and a high-fidelity simulation, into the nursing curriculum may contribute to the further development of nursing education.
Endoscopy has a crucial role in the diagnosis, management, and surveillance of inflammatory bowel disease (IBD). It contributes in supporting the diagnosis of IBD with the clinical history, physical ...examination, laboratory findings, and targeted biopsies. Furthermore, endoscopy has a significant role in assessing disease activity and distribution in treatment efficacy evaluation, post-surgical recurrence risk, and cancer surveillance in patients with long-lasting illness. Endoscopy also provides therapeutic potential for the treatment of IBD, especially with stricture dilatation and treatment of bleeding. Small bowel (SB) endoscopy (capsule endoscopy and device-assisted enteroscopy) and cross-sectional radiologic imaging (computed tomography enterography and magnetic resonance enterography) have become important diagnostic options to diagnose and treat patients with SB Crohn's disease. We reviewed the present role of SB endoscopy in patients with SB Crohn's disease.
In simulation education, learning does not occur without certain debriefing activities. The purpose of this study was to identify debriefing practices in simulation-based nursing education in Korea.
...Ninety-six nursing faculty members responsible for simulation education participated in this study from January to April, 2015. Data were collected using a revised version of Fey's Final Survey Questions: Debriefing Practices (2014) and analyzed by descriptive statistics.
Simulation education is a required course in the majority of Korean nursing colleges, and 52.7% of them have replaced the clinical practicum with simulation. Those who completed training for debriefing were more likely to support students' emotional reactions to simulation and provide feedback. The Gather–Analyze–Summarize model and the Debriefing Assessment for Simulation in Healthcare model were most frequently used for debriefing.
There is a need to develop more systematic and effective training programs that encompass theories for implementing and evaluating debriefing practices in simulation-based nursing education in Korea.
•This study is to understand the current usage of simulation-based nursing education and debriefing in South Korea.•Majority of participant's concurred simulation-based nursing education was conducted in nearly all educational courses.•Instructors are very interested in the operating method of debriefing and their role.
We present an exhibition information model (EIM) by analyzing quantitative data for curators to configure the exhibition space. The proposed method consists of three steps: i) probabilistic interest ...prediction model (IPM), ii) mutual interest-based time prediction, and iii) spatial analysis for path prediction. The proposed method can be simulated in advance using the information of visitors and characteristics of the exhibition. The proposed simulation method can be applied to analyze the visitor's behavior by detecting and tracking moving objects.
This paper presents an automatic liquid level detection algorithm for a beverage refilling service in a restaurant. The automatic detection of liquid level provides the amount of residual of ...customer's beverage using a general-purpose surveillance camera deployed in a restaurant. The proposed system consists of three modules i) extraction of a cup and beverage region using color-based region segmentation by K-means clustering, ii) edge detection of the cup and beverage region, and iii) liquid level estimation based on edge detection. Using a general-purpose CCTV camera and a set of relevant image processing algorithms, the proposed system can be one of important applications of internet of things (IoT) service.
Fe L3-edge, Mn L3-edge, Na K-edge, and O K-edge X-ray absorption spectroscopy (XAS) data were obtained from Na0.67Fe0.25Mn0.75O2 (FMO) and Na0.67Li0.2Fe0.2Mn0.6O2 (LFMO) primary particles in pristine ...and charged states with a spatial resolution of 30 nm using scanning transmission X-ray microscopy (STXM). The XAS data showed that the average oxidation number of Fe ions was +3 for all particles. For Mn ions, it was +3.9 (charged) and +3.6 (pristine) for the LFMO particles and +3.6 (charged) and +3.5 (pristine) for the FMO particles. Further, for Na ions, the value was +1 for both particles in the pristine state. The changes in the oxidation numbers implied the strong effect of Mn ions on charge exchange as the Na ions were intercalated. Compared to the FMO particles, the LFMO particles showed that (i) the Fe ions undergo fewer spectral feature changes during charging, (ii) Mn ions exchange charges dominantly toward the 4+ ion in the charged state, (iii) both the Mn and Fe ions possess more homogeneous spectral features in the charged state, (iv) the O ions undergo fewer spectral feature changes upon charging, and (v) Na ions possess more homogeneous spectral features in the pristine state. These spectral features support the enhancement of the structural stability of LFMO particles.

Synergistic hydrate inhibition of kinetic and thermodynamic inhibitors is a promising strategy for preventing hydrate blockage in flowlines. Some research has been conducted on structure II natural ...gas hydrates; however, there have been few reports on the synergistic inhibition of structure I (sI) methane hydrates. Herein, we synthesized LCST-modulated kinetic hydrate inhibition copolymers using reversible addition-fragmentation chain-transfer polymerization and tested their performance on sI methane hydrate inhibition in the presence of a monoethylene glycol (MEG) synergist. All copolymers generally inhibited hydrate formation, while the experimental systems were thermodynamically under-inhibited by MEG. We demonstrated that the synergistic inhibition of N-isopropylacrylamide-based copolymer and MEG are effective in preventing hydrate blockage and hydrate re-formation for systems with methane-dominant flow, and methane hydrate development in subsea sediments. These inhibition polymers with narrow phase transition regions and well-controlled lower critical solution temperatures might be helpful in preventing fouling problems caused by unexpected precipitation and designing more economical processes for flow assurance.
