The purpose of this study was the implementation of a simulation for a subsea production system. This subsea production system is installed under environments with high pressure and low temperature. Most of the processes for oil and gas production occur in the subsea equipment. Therefore, an understanding and study of subsea production systems is very difficult because people cannot directly observe the processes occurring in the subsea production system. A simulation system can be a useful solution for this difficult problem. In this research, information models and a 3-D graphic model of the subsea equipment were built using the object-oriented technology and 3-D CAD. The entire system was implemented with the help of simulation software, 3-DVIA Virtools. The simulation system for the subsea production system was tested using several production process scenarios. The results of the tests showed that the simulation system is very useful for understanding a subsea production system and could be a good educational tool.

공차란 각 부품들이 기구적으로 조립되었을 때 원하는 수준의 기능성을 확보할 수 있도록 각 부품의 기하학적 형상이나 위치에 대해 허용하는 치수의 변동량을 의미한다. 또한 공차해석이란 부품들이 조립되었을 때, 각 부품의 공차가 조립품에서 어떻게 누적되어 미치는 영향을 분석하는 일련의 절차를 의미한다. 만일 누적된 공차의 분산이 규정된 일정 수준의 범위를 벗어나면 조립품의 품질에 문제가 발생하기 때문에 당초 설정한 부품의 공차를 수정해야 하며, 이러한 과정을 공차설계라고 한다. 이 논문에서는 휴대용 의료기기의 설계단계에서 공차해석과 공차설계를 위해 몬테카를로 시뮬레이션 기법을 활용한 사례를 소개한다. 이러한 시뮬레이션 연구를 통하여 제품의 조립성과 기능성을 개선시킬 수 있다.

Deterioration of the outdoor thermal environment in urban areas has become worse and worse due to the urbanization and overpopulation, etc. Most of existing researches about thermal environment are focused on the indoor environment in which the radiation heat exchange is relatively constant. However, the outdoor thermal environment is changed with time passages, because the thermal environment is highly effected by solar radiation. Thus, to simulate the outdoor thermal environment with accuracy, the solar radiation calculation should be considered, and the radiation heat exchange between building surface and ground surface should be calculated. The purpose of this study is to develop the simulator that can be possible to evaluate the outdoor thermal environment and pedestrian thermal comfort. In this paper, a new method which is coupled with convective heat transfer simulation and radiative heat transfer simulation will be proposed. And the coupled simulation method will be described through case study for outdoor thermal environment. From the results of simulation, the coupled simulation proposed in this study can assess the outdoor thermal environment with accuracy.

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.

Purpose: The aim of this study was to evaluate differences of pre-post simulation training in problem solving ability, performance confidence, and critical thinking skill according to degree of nursing students' self-leadership. Methods: This study was a descriptive survey using a self-report questionnaire. One hundred eighty nursing students participated in this study which programed a simulation scenario of pre-post operative patients' care. Descriptive statistics, paired t-test, ANCOVA with IBM SPSS 21.0 program were used for data analysis. Results: After the simulation training, both the above-average subjects and below-average subjects in self-leadership significantly improved their problem-solving ability, performance confidence, and critical thinking skill. compared with their previous level. The subjects who rated above-average in self-leadership, improved their degree of problem-solving ability, performance confidence, and critical thinking skill significantly more than those who were below-average in self-leadership. Conclusion: Self-leadership of nursing students is an important element in effective simulation training.

Study on the electron transport coefficient in mixtures of CF4 and Ar, have been analyzed over a range of the reduced electric field strength between 0.1 and 350[Td] by the two-term approximation of the Boltzmann equation (BEq.) method and the Monte Carlo simulation (MCS). The calculations of electron swarm parameters require the knowledge of several collision cross-sections of electron beam. Thus, published momentum transfer, ionization, vibration, attachment, electronic excitation, and dissociation cross-sections of electrons for $CF_4$ and Ar, were used. The differences of the transport coefficients of electrons in $CF_4$ mixtures of Ar, have been explained by the deduced energy distribution functions for electrons and the complete collision cross-sections for electrons. The results of the Boltzmann equation and the Monte Carlo simulation have been compared with the data presented by several workers. The deduced transport coefficients for electrons agree reasonably well with the experimental and simulation data obtained by Nakamura and Hayashi. The energy distribution function of electrons in $CF_4-Ar$ mixtures shows the Maxwellian distribution for energy. That is, $f({\varepsilon})$ has the symmetrical shape whose axis of symmetry is a most probably energy. The proposed theoretical simulation techniques in this work will be useful to predict the fundamental process of charged particles and the breakdown properties of gas mixtures. A two-term approximation of the Boltzmann equation analysis and Monte Carlo simulation have been used to study electron transport coefficients.

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.
