        This study aimed to explore nursing students' experience of learning cardiopulmonary resuscitation (CPR) in a web-based virtual simulation (vSim) through analysis of the reflection journals. Method: From June to July 2020, data were collected from 48 fourth-year nursing students who performed the simulation by reviewing prompt feedback on their CPR performance. The contents of the reflection journals were analyzed using NVivo qualitative data analysis software. Results: Nursing students experienced unfamiliarity with the English-based virtual environment as well as psychological pressure and anxiety about emergencies. Incorrect interventions were identified in the following order of frequency: violation of defibrillator guidelines, missing fundamental nursing care, error in applying an electrocardiogram monitor, inadequate initial response to cardiac arrest, insufficient chest compression, and inadequate ventilation. Lastly, the participants learned the importance of embodied knowledge, for knowing and acting accurately and reacting immediately, and their attitudes as nurses, such as responsibility, calmness, and attentiveness. Learning strategies included memory retention through repetition, real-time feedback analysis, pre-learning, and imagining action sequences in advance. The level of achievement, time required, CPR quality, and confidence improved with behavior-modification strategies developed through self-reflection. Conclusion: Educational interventions that are based on understanding accurate algorithms can strengthen selfawareness of mistakes to improve efficient imparting of CPR education.

        Purpose: This study aimed to examine the learning immersion, learning satisfactory, and learning confidence differences after virtual and then laboratory simulations. Methods: A two-group cross-over design was used, and the participants included 148 senior nursing students (74 teams). The treatments had virtual and then laboratory simulations. The data were analyzed using independent t-test, repeated measures ANCOVA and Chronbach’s αcoefficient using the SPSS/ WIN 21.0 program. Results: Nursing students who experienced laboratory simulation after virtual simulation were different totally or partially with nursing students who experienced virtual simulation first in learning immersion, learning satisfaction and, learning confidence. Conclusion: Effects based on order of simulation were different. To increase learning immersion, laboratory simulation was done before virtual simulation. Learning satisfaction and learning confidence, it were not affected by order of simulation type but by number. Repeated studies require clearly investigating the effects based on order of simulation type.

        Purpose: This study aimed to explore the meaning of simulation practice after experiencing virtual simulation for nursing students with clinical practice experience. We attempted to determine a nursing simulation strategy as an alternative to the clinical practice in the COVID-19 pandemic. Methods: The participants were seven nursing students who experienced clinical practice and completed alternative virtual simulation practice in the COVID-19 pandemic. The data were collected through in-depth interviews and analysed using the phenomenological methodology. The key question was “what is the meaning and nature of child health nursing practice using virtual simulation in the COVID-19 pandemic?” Results: The significant statements were categorized into 14 themes, 7 theme clusters, and 2 categories. The categories extracted were “a sense of difference between virtual and reality” and “experience systematic learning transfer.” Conclusion: Practical education through nursing simulation is important for students to experience a systematic and efficient learning. Additionally, simulation educators should produce various efforts to help students achieve the learning outcomes, such as scenarios, class environments, and instructor preparation, to reduce their sense of separation from practice.

        PURPOSES : This study aimed to develop data conversion of NGII HD maps to OpenDRIVE format for virtual road implementation for autonomous-driving verification. METHODS : A method of defining the reference line of OpenDRIVE on the centerline of an NGII HD map is proposed. According to the construction characteristics of the NGII HD map, the optimal conversion method through parametric cubic polynomials was used in the form of piecewise and clamped cubic polynomials. RESULTS : The study focused on curved roads that may cause problems when converting HD map data into OpenDRIVE formats. As a result of data conversion, a reference line was defined to precisely follow the alignment of NGII HD maps drawn based on MMS data, and a lively virtual road was reproduced through road lane width and lane expression. CONCLUSIONS : A virtual road in the same environment as a real road, which is one of the important factors in verifying autonomous driving technology through virtual driving simulation, was constructed. The piecewise-polynomial normal was 0.008 m on average, and as a result of calculating the distance between the endpoint coordinates of the road object and the endpoint coordinates of the converted road object on the NGII HD map, the difference between the two points was 0.163 m on average. The clamped cubic polynomials normal was observed to be an average of 0.170 m.

        In spite of international efforts to control nuclear weapons and chemical, biological, and radiological (CBR) weapons, North Korea obtains and sells CBR weapons illegally. As a result, the worldwide threat of CBR weapons is increasing. Unfortunately, civil defense education and training for CBR weapons have not been adopted for real situations because of the long period of absence of an actual combat. In this study, virtual training scenarios that are applied to the simulation were made in 5 steps to cope with CBR situations. These scenarios are expected to have three effects. First, trainings can be improved with experience and education. Second, the problems and health hazards of CBR weapons and supplies can be solved with CBR virtual training simulation experience. Finally, corresponding effects can be recognized and predicted in real situations through roles and mission procedures of simulation scenario.

        This paper focuses on the mackerel's visual ability and swimming capability, and aims to describe the behavior in capture and escape process by trawl. The visual sensory systems and reaction behavior based locomotory capability were analyzed and simulated. The ability of fish to see an object depends on the light intensity and the contrast and size of the object. Swimming endurance of the fish is dependent on the swimming speed and the size of the fish. Swimming speeds of the fish are simulated 3 types of the burst speed, the prolonged speed and the sustained speed according to the time they can maintain to swim. The herding and avoiding is typical reaction of the fish to the stimuli of trawl gear in the capture process. These basic behavior patterns of the virtual mackerel to the gear are simulated. This simulation will be helpful to understand the fishing processes and make high selectivity of fishing.
