A computer simulation method for textile designs was developed using a generic-purpose graphics program, LUMENA and its results were applied for costume design simulation. Its design performance was comparable with those using specialized design package programs which are in general very expensive. Three areas of textile design, print pattern design, weaving design, and knitting design, were covered. In the print pattern design simulation, a gird network library was constructed by using basic methods of repeat, and a pattern library by scanning existing print patterns. Through the modification and synthesis of library patterns, many new print patterns could be obtained. In the weaving design simulation, a thread library and a draw-down library were constructed. Using them, simulations of woven textile structures were carried out. In the knitting design simulation, a stitch library and a detail library were made from various types of knit stitch and detail drawings of knit costume, respectively. They were used to make structural knitting patterns and jacquard knitting designs. Using those simulated textile designs, costume design simulation was carried out.

A simulation program is developed for the optimal design of small scale district heating and cooling system. Main features for the simulation program are the reliability and the easiness for the optimal design of the DHC(District Heating and Cooling) systems. In order for implementing those features, the operational characteristics according to the prime movers is modeled based on the materials of efficiency as a function of operational load. The unit energy load model is also developed extensively for several building types, of which the corresponding district consist, such as apartment complex, hotel, hospital, buildings for business and commercial use respectively. The specific features and the overall procedure of the simulation are described in brief in this paper. The results of the simulation for several test cases will be presented in subsequent study.

Purpose: The purpose of this study was to determine the effects of simulation based training using a post-operating rehabilitation case on learning outcomes in nursing students. Methods: A quasi-experimental research design (one group pretest and posttest design) and a questionnaire for measuring learning outcomes were used in this study. The participants were 35 students in a college of nursing. Data were collected before the program and immediately after the program that applied simulation based training using a post-operating rehabilitation case consisted of 4th running and debriefing for 26 hours. With SAS 9.2 program, descriptive statistics and paired t-test were used to analyze the data. Results: There were statistically significant increases in necessity (p=.001) and performance of learning outcome (p<.001) of simulation based training using a post-operating rehabilitation case among students in a college of nursing. Conclusion: The findings of this study demonstrate that simulation based training using a post-operating rehabilitation case for nursing students may increase performance of learning outcomes on clinical reasoning and critical thinking.

There are various types of energy simulation tool to predict both thermal load and energy use. However, the problem about these software is that they have too much input variables and need expert with skills to run the simulation. Therefore, the purpose of this study is to develop the thermal analysis simulation program with input variables which eliminates coordinates of building components instead of using full coordinates by using DOE2. Since the simulation engine of the program is DOE2, the validity of S-DOE is performed by comparing peak heating and cooling load results with VisualDOE and annual energy use results with actual energy use of 1996. The results have shown that there are little difference between VisualDOE and S-DOE. Also it showed that there are little difference between actual energy use and S-DOE energy use results. S-DOE took less time to model a building than VisualDOE. These results reveals that the application of S-DOE have potentials in accurately predicting both energy load and energy use of the building and still have an advantage of taking less time to model a building.

Purpose: This study aimed to confirm the effects of a simulation-based program on knowledge and clinical performance in the post-operative management of emergency patients. Methods: This was a pre- and post-research design with a nonequivalent control group and randomly sampled 29 experimental and control groups, respectively from nursing department juniors for 4 weeks from September of 2014. The experimental group received lectures, team study, team simulation, and debriefing in post-operative management of simulation-based emergency patients and control group conducted in the traditional lecture-type setting. Educational learning effects were measured by using the knowledge and clinical performance measurement tools of 15 and 20 items, respectively. Data were analyzed by using the SPSS program, including frequency, ratio, and results from the Chi-square test, Fisher's exact test, Kolmogorov-Smirnov test, t-test. Results: Our research results indicate that, the experimental group showed significantly higher knowledge and clinical performance score compared with the control group. Conclusion: We confirmed that education on post-operative management of simulation-based emergency patients was an effective educational method to improve the knowledge and clinical performance of nursing students.

Purpose: The purpose of the study was to determine the effects of Simulation-Based Training on anxiety, depression and self-efficacy in nursing students. Methods: A quasi-experimental research design (one group pre-test and post-test design) and a questionnaire for measuring anxiety, depression and self-efficacy were used in this study. The participants were 97 students of a nursing college. Data were collected before the program and immediately after the program. Means, SD, paired t-test, and Cronbach's ${\alpha}$ with the SPSS/WIN 12.0 program were used to analyze the data. Results: There was a statistically significant decrease in anxiety (p=.012) and a statistically significant increase in self-efficacy (p=.048), but not in depression (p=.439) among the nursing students who underwent Simulation-Based Training. Conclusion: From the findings of this study, it was demonstrated that Simulation-Based Training interventions had effects on anxiety and self-efficacy. Therefore, future and/or repeat studies will actively apply Simulation-Based Training interventions.

This study evaluates the effect of structured debriefing for a business simulation game for university students. The program provides an authentic learning experience of real-world business management by allowing learners to make decisions related to R&D, marketing, production, and finance through a business simulation game, and check the results in real time. In 2022, University A and B each ran a business simulation game-based program as an extra-curricular activity. University A conducted a traditional instructor-led debriefing where the instructor explained the summarized process and results, while University B implemented a structured debriefing which had been developed based on Gibbs' and 3D models. To assess the effect of the structured debriefing compared to the traditional instructor-led debriefing, business knowledge and entrepreneurship competencies were measured three times. Repeated measures ANOVA was used to test for the differences between the two groups and to examine interaction effects between group and time. The structured debriefing group achieved statistically significantly higher academic scores than the traditional instructor-led debriefing group at the post-test and in 2 weeks. There was no statistically significant difference between the groups in terms of entrepreneurship competencies. There was no interaction effect between group and time, both in academic achievement and in entrepreneurship competencies. In conclusion, the simulation game-based program integrated with the structured debriefing session is more likely to have a stronger impact on academic achievement and its retention.

This study performed a survey on the need for an automobile accident-simulation training program for 60 emergency workers and nine emergency medical professors. The results showed that the need for cervical spine immobilization use was highest (76.8%) in first-aid requiring simulation training, and the need for head injury was highest (75.4%) in the scenario requiring simulation training. Based on the 43-month working experience of emergency workers, the uses of pneumatic anti-shock garment, KED, and the need for rapid extrication were significantly different between the two groups (p=0.01, p=0.05). In addition, the scenario showed statistically significant differences in the need for face, abdomen, and other injuries in both group (p=0.05, p=0.04, p=0.03). The needs of emergency workers and emergency medical professors for an automobile accident simulation-training program were high, and the development of a simulation program is needed.
