Purpose: This study was conducted to examine the effects of simulation education integrated with problem based learning (SIM-PBL) on clinical competency and self-efficacy in post operation nursing care for children. Methods: This study was a quasi-experimental design. Thirty six students in the third year of a 4-year baccalaureate nursing program were recruited conveniently and assigned to the control or intervention groups using time difference. Students were all in a pediatric nursing clinical practicum. The control group received the regular clinical practicum in a hospital setting. For the intervention group, a SIM-PBL education replaced 150 minutes of their clinical practicum. Results: The intervention group showed greater improvement in two areas of clinical competency compared with the control group; physical assessment (t= 3.019, p=.005) and post operation advice (t=2.428, p=.021). However, no statistically significant differences in improvement in any areas of self-efficacy were found between two groups. Conclusion: The results indicate that the SIM-PBL education is effective in improving some areas of clinical competence, but not self-efficacy in post operation nursing care for children. Further study is needed to develop SIM-PBL programs for various clinical topics and evaluate the effectiveness on the learning outcomes.

The purpose of this study is to compare the effects on nursing students' knowledge, performance confidence, and skills from combined virtual IV simulator and mannequin arm IV cannulation training against training with a mannequin arm only. A non-equivalent control group pretest-posttest experimental study was carried out. Ninety-three sophomore nursing students who were just beginning their fundamental skills training were recruited. Participants were divided into two groups (46 for the combined group and 47 for the mannequin-only group). Data were collected from March 18-29. For the experimental group, both virtual IV simulator and mannequin-arm training were provided for 30 minutes (15 minutes each). For the control group, training for 30 minutes with a mannequin arm only was provided. After intervention, there was no statistically significant difference in the knowledge score between the two groups (F=2.52, p=.116). However, there was a significant improvement in performance confidence (t=2.14, p=.035) and nursing skills (t=5.34, p<.001) in the experimental group, compared with the control. Overall, this study provides empirical evidence that the combination of virtual IV simulator and mannequin arm training may further enhance nursing students' performance confidence and nursing skills.

This study has been made to research effect of neurofeedback training on the Brain Quotient and baduk strength whose EEC data were obtained both before and after the neurofeedback training from 15th June, to 15th September in 2007. Brain waves were measured on the frontal lobes of subjects (30 baduk players - the experimental group 15 under neuroffedback training and the control group 15 subjects) and analyzed by calculating eight brain quotients characterizing behaviors of EEG rhythms effectively. The results of the analysis show that the experimental group has the higher indexes Attention Quotient(left) p=.041, (right)p=.007, Stress Quotient (left) p=.020, and Stress Quotient (right) p=.019 show statistically significant difference between two groups. The research data show that the experimental group have the higher average than the control group in Baduk strength examination p=.021 after the neuroffedback training. As the brain waves are adjusted by timeseries linear analysis, the brain function quotients can reflect the functional states of the brain.

This paper presents a study investigating the effects of VR learning style on user attention and memory. The study involved users performed the guided or unguided style learning in the virtual environment while user attention was measured through physiological sensors (EEG, ECG, and GSR) and an eye tracking system. The users experienced the five specific events in a virtual environment associated with different stimuli, while they were given more specific goals during the guided task whereas they were given more goal asking them to actively search for the interesting items during the unguided task. The subject's attentions workload, feelings, memories about VR experience were measured by using a variety of physiological sensors during the task, video analysis, and post test survey. The results showed that the unguided task followed by the guided task made a considerable learning effect by giving a preview effect to the user. Moreover, the guided task drew more user attention and mental workload than the unguided task did.

최근에는 사람과 기계가 자유롭게 대화를 주고받을 수 있는 자유 주제 대화 시스템(Open-domain Dialogue System)이 다양한 서비스에 활용되고 있다. 자유 주제 대화 시스템이 더욱 다양한 답변을 제공할 수 있도록 사전학습 기반의 생성 언어모델이 활용되고 있지만, 답변 제공의 안정성이 떨어져 검색을 활용한 방법 또한 함께 활용되고 있다. 검색 기반 방법은 사용자의 대화가 들어오면 사전에 구축된 데이터베이스에서 유사한 대화를 검색하고 준비되어있는 답변을 제공하는 기술이다. 하지만 멀티턴으로 이루어진 대화는 일반적인 문서의 문장과 다르게 각 문장에 대한 발화의 주체가 변경되기 때문에 연속된 발화 문장이 문맥적으로 밀접하게 연결되지 않는 경우가 있다. 본 논문에서는 이와 같은 대화의 특징을 고려하여 멀티턴 대화를 효율적으로 임베딩 할 수 있는 DBERT(DialogueBERT) 모델을 제안한다. 기존 공개된 사전학습 언어모델 기반의 문장 임베딩 모델과 비교 평가 실험을 통해 제안하는 방법의 우수성을 입증한다.

This research is about the effect on children's brain before and after learning Baduk. The research was performed on 20 pupils attending I Baduk school with the contrast group of 20 pupils who did not take Baduk instruction. The pre-test on the brain waves before learning Baduk were measured from October 27, 2008 to November 7, 2008 and the post-test on the brainwaves after learning Baduk were measured from November 2, 2009 to November 4, 2009. The result confirmed the differences of both resistance activity quotient and emotion quotient. The result of the study suggest baduk study possibility in positively affecting the subjects' brain activation and emotion.

This study investigated whether Korean learners improve acoustic cue weights to identify Korean lenis and aspirated stops in the direction of native values through perception training that focused on contrasting the stops in various phonetic contexts. Nineteen native Chinese learners of Korean and two native Korean instructors for the perception training participated in the experiment. A training group and a non-training group were divided according to pretest results, and only the training group participated in the training for 5 days. To estimate the perceptual weights of the stop cues, a pretest and a posttest were conducted with stimuli whose stop cues (F0 and VOT) were systematically manipulated. Binary logistic regression analyses were performed on each learner's test results to calculate perceptual β coefficients, which estimate the perceptual weights of the acoustic cues used in identifying the stop contrast. The training group showed a statistically significant increase of 0.451 on average in the posttest for the coefficient values of the F0, which is the primary cue for the stop contrast, whereas the non-training group showed an insignificant increase of 0.246. The patterns of change in the F0 use after training varied considerably among individual learners.

The purpose of this study is to investigate the effect of flipped learning-based health assessment education on academic achievement of nursing students. The subjects of the study included nursing students attending second year at university. For 10 weeks, the experimental group was exposed to flipped learning-based classes, and the control group was provided with traditional lectures and team learning-based classes. In the intermediate evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant, and in the final evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant. The integrated knowledge score, evaluated three times after the end of the training, was higher in the experimental group than in the control group. These results suggest that flipped learning is an effective teaching and learning method for improving knowledge and performance of nursing students. Therefore, the application of flipped learning in various nursing education areas should be studied.
