Purpose: The purpose of this study was to identify the effects simulation-based education combined team-based learning (SBE combined TBL) compared to simulation-based education (SBE) on undergraduate nursing students. Methods: A non-equivalent control group design with pre-and posttest measures was used. The participants in the study were 181 students. The SBE combined TBL group consisted of 84 senior students in 2013, and the SBE group consisted of 97 seniors in 2014. Collected data were analyzed using chi-square, independent t-test and ANCOVA with the statistical package SPSS 22.0 for Windows. Results: There was a significant improvement in communication skills, nursing performance confidence, team efficacy, and team performance scores in the SBE combined TBL group compared to the SBE group (t=2.45, p=.015; F=4.30, p=.040; t=3.06, p=.003; t=8.77, p<.001). However, there was no statistically significant difference in self-directed learning between the groups. Conclusion: SBE combined TBL compared to SBE is an effective teaching and learning method to enhance various positive educational outcomes for nursing students. Therefore, we suggest that future studies investigate the development of an integrated course in which team-based learning is applied to theoretical sessions and simulation-based training.

Numerical simulation based on the superposition of ring waves generated by the linear periodic source distributions for the plunger type wave maker was accomplished. The characteristics of directional spreading function were investigated. Mirror images are also introduced to consider reflections of side-wall together with the reflection coefficient to account for the imperfect reflection from the real side wall in the long experimental towing tank. Unexpected spurious waves, resulting from the combined effect of finite breadth of segmented wave maker, wavelength and main wave maker, wavelength and main wave propagating direction, were observed in the line source method and also in the analysis of the directivity. The influence of spurious waves to the directional spreading function was also investigated.

Purpose: This study was done to develop and evaluate an algorithm-based simulation scenario for emergency measures for high-risk newborns presenting with apnea. Methods: A one shot case study design was used to evaluate the algorithm-based simulation scenario. Effects of the developed simulation scenario were evaluated using the Simulation Effectiveness Tool (SET) and the Lasater Clinical Judgement Rubric (LCJR). From March to November 137 senior nursing students completed the simulation using this scenario. Results: The eight-frame simulation scenario was developed based on the Neonatal Resuscitation Program (NRP) and the nursing clinical judgment process. After use of the scenario, overall scores for SET and LCJR were 21.0 out of 26.0 and 32.4 out of 44.0 respectively. There were no significant differences in scores according to general characteristics. Positive correlation coefficients were identified among overall and subcategories of SET and LCJR. In addition, students provided positive feedback on the simulation experience. Conclusion: Considering that nursing students have limited access to high-risk newborns during their clinical experience and that newborns presenting apnea are common in the neonatal intensive care unit, the simulation scenario developed in this study is expected to provide nursing students with more opportunities to practice emergency measures for high-risk newborns.

Due to the rapid increasing in the aged population, it calls for social countermeasures urgently. Especially, there are increasing needs of space environment to support physical and spiritual characteristics of elderly. When designing space environment including house, there are growing consideration for elderly and extending appreciation of aging. The purpose of this study is to investigate the perception on environment planning for the seniors among university students who majoring in Housing & Interior Design and who visited the Aging Simulation Center located in Seoul. The Aging Simulation Center gives a chance of space design to support the elderly based on the experiences of daily living for the designers who design environment for elderly. Questionnaire survey was conducted to obtain data from 93 university students in their 20s majoring in housing and interior design who visited the Aging Simulation Center. The research findings showed that the recognition for design elements of residential environment for the elderly of respondents was changed toward positive way after visiting the Aging Simulation Center. The Aging Simulation Center was an effective educational environment for the preliminary designers to understand aging and the importance of appropriate design for users' needs. That is, aging simulation space can improve recognition of necessity of universally designed environment to support the elderly. Handrails around bathtub and wash basin, stair slope, electric auto-level controlled kitchen counter and kitchen cabinet were especially perceived for the respondents as very essential design elements to support the aged.

Purpose: The purpose of this study was to develop a scenario and evaluate students' performance in simulation learning of care for patients with asthma in emergency units. Methods: Meetings of experts were used to develop a scenario based on actual patients and textbook material. An evaluation protocol was developed to evaluate the simulation learning. The scenario was used in 2006 with six groups of 26 senior nursing students who participated voluntarily. Results: The scenario was developed according to the nursing process for 15 minutes of simulation learning. The nursing students were able to demonstrate their knowledge and skills. The results showed a need to improve problem solving ability. In the self-evaluation, the students reported that simulation learning helped them to integrate their knowledge to practice and recognize their weaknesses and strengths. However, the scores for self-confidence about patient care after the simulation learning were low (4.8/10). Conclusion: The scenario in this study gave the students the experience of providing qualified and secure nursing care under conditions similar to reality. Further development of a variety of scenarios for simulation learning is needed.

InnovVizwas designed and developed anew as avisualization and simulationtool to present innovation and strategy information. The InnovViz system employs two key types of technology, namely mixed reality (MR) and neural network (NN). An experiment was conducted to examine the usability, acceptance and possible adoption of this new system. Participants comprised 4 experts from 4 top performing entrepreneurial firms and 161 master degree students from 2 leading universities. The study used a modified UTAUT model and a cognition and perception model. The results revealed that when the InnovViz was introduced, the key drivers to adoption are Facilitating Conditions (FC) and Voluntary to Use (VOL). Adequate knowledge and sufficient resources were found to strongly affect FC construct. The expert's rating of a firm's innovation and performance was more congruent with senior students with a technology-background than with a finance and accounting-background. InnovViz was seen as providing complex information with an ease of use and usefulness for showing data and assessment. Among the three types of visuals depicted by InnovViz, experts rated their usefulness in descending order as follows: Cube, Tetrahedron and Saturn. Finally, experts found backward simulation to be slightly more useful for assessment than forward simulation.

In laser materials processing, localized heating, melting and evaporation caused by focused laser radiation forms a vapor on the material surface. The plume is generally an unstable entity, fluctuating according to its own dynamics. The beam is refracted and absorbed as it traverses the plume, thus modifying its power density on the surface of the condensed phases. This modifies material evaporation and optical properties of the plume. A laser-produced plasma plume simulation is completed using axisymmetric, high-temperature gas dynamic model including the laser radiation power absorption, refraction, and reflection. The physical properties and velocity profiles are verified using the published experimental and numerical results. The simulation results provide the effect of plasma plume fluctuations on the laser power density and quantitative beam radius changes on the material surface. It is proved that beam absorption, reflection and defocusing effects through the plume are essential to obtain appropriate mathematical simulation results. It is also found that absorption of the beam in the plume has much less direct effect on the beam power density at the material surface than defocusing does and helium gas is more efficient in reducing the beam refraction and absorption effect compared to argon gas for common laser materials processing.
