  • Purpose of this study is to analyze the roles and strategies of imagistic simulation observed in mental simulation about problematic situation of prediction, and thereby identify the process of generating prediction, explanation and sophistication. For this study, a framework for mental simulation process and strategy based on literary research was developed and content was validated from four experts of science education. This study was participated by 10 preliminary elementary school teachers, and a total of 20 cases were gathered for two thought experiment tasks based on the think-aloud method. The results were as follows: First, mental simulation process described based on the seven elements of 'perception,' 'interpretation,' 'statement of initial representation,' 'running imagistic simulation,' 'identifying result of simulation,' 'identifying alignment' and 'restatement structured representation.' The study confirmed that initial representation by interpreting related concepts and running imagistic simulation a number of times to develop explanation and prediction. Second, the study identified the use of strategies to enhance simulation such as 'zoom in,' 'partition,' 'dimensional enhancement,' 'dimensional reduction,' 'remove,' 'replace' and 'extreme case.' Running spatial transformation that uses strategy to enhance simulation contributed to discovering mechanism elements in problematic situations.

  • Purpose. This study was conducted to identify effects of the high fidelity simulation for nursing students. Methods. A non-equivalent quasi-experimental design was used to experimental group (N=43) and control group (N=39) for 8 weeks, 5 times from September 26 to November 9, 2013. Clinical performance was measured by using standardized patients. Critical thinking was measured through the questionnaire and clinical judgement was measured through observation by Lasater's rubric. Results. Clinical performance (F=211.15, p<.001), critical thinking (t=3.00, p<.004) and clinical judgement (t=7.60, p<.001) were significantly higher in experimental group with simulation education program than control group. Conclusion. Simulation education program were effective to improve clinical performance, critical thinking disposition and clinical judgement for nursing students.

  • This study proposes a digital twin implementation method through simulation so that the manufacturing process can be optimized in a manual manufacturing site. The scope of the proposal is a knowledge management mechanism that collects manual motion with a sensor and optimizes the manufacturing process with repetitive experimental data for motion recognition. In order to achieve the research purpose, a simulation of the distribution site was conducted, and a plan to create an optimized digital twin was prepared by repeatedly experiencing the work simulation based on the basic knowledge expressed by the worker's experience. As a result of the experiment, it was found that it is possible to continuously improve the manufacturing process by transmitting the result of configuring the optimized resources to the physical system by generating the characteristics of the work space configuration and working step within a faster time with the simulation that creates the digital twin.

  • This study aimed to determine the effects of simulation-based practice education on nursing students' employability, career exploration behavior and decision-making self-efficacy. A non-equivalent control group pre-posttest of quasi-experimental design was used. A total of 120 nursing students located in J provinces, 60 students for the experimental group and 60 students for the control group. Study participants were a third-year student at college of nursing student. The experimental group participated in the study for 6 weeks. The results showed that the simulation-based practice education significantly improved employability(t=-2.31, p=.023) and career exploration behavior(t=-3.05, p=.003) of nursing students. However, there was no significant difference in the decision-making self-efficacy(t=-.87, p=.387). In conclusion, simulation-based practice education should be strengthened because it is useful for education of nursing students.

  • Air qualify monitoring if a primary activity for industrial and social environment. Especially, the VOCs(Volatile Organic Compounds) are very harmful for human and environment. Throughout this research. we designed sensor array with various kinds of gas sensor, and the recognition algorithm with ANN(Artificial Neural Network : BP), respectively. We have designed system to recognize various kinds and quantities of VOCs, such as benzene, tolylene, and xylene.

  • Chuncheon city is constructing a world-wide famous theme park, Chuncheon Legoland. In this study, analysis of the city traffic infrastructure for Chuncheon Legoland has been performed. We first reviewed the current city traffic condition with regard to the park. We then defined potential customers and arrivals, streets, and routing street sequences to the park. Based on a measure, occupation ratio, reflecting traffic condition we designed experiments for analysis and obtained results from simulation. Our results indicate that severe traffic delay is expected during the peak season and is significant especially in streets 9,11,16. We performed additional experiments with increasing the number of lanes of them and obtained improved results.

  • This study, nonequivalent control group pretest-posttest design was to identify the effects of simulation-based training for basic life support on the knowledge and skills of the nursing college students. The subject were 16 participants in the experimental group who trained with simulation-based and 17 participants in the control group who trained with traditional education methods among second grade of D college in D city. Data was collected from 24th August to 1st September 2009. The data were analyzed with Fisher's exact, independent t-test, paired t-test and ANCOVA using SPSS/PC 12.0 win. The results were as followed. Firstly, BLS knowledge of the experimental group weren't significantly different with the control group(F=.568, p=.573), Secondly, BLS skills of the experimental group were significantly different with the control group(F=19.407, p=.000). These findings suggest that simulation-based training for basic life support improved the competence on basic life support of nursing college students. Therefore, the result suggested that nursing department professor applicate simulation-based training to improve nursing college student's ability to perform basic life support.
