The purpose of this study was to develop a nursing education program using Web-based simulation for the care of patients with intracranial pressure. An additional aim was to verify the effectiveness of nursing knowledge, problem-solving competency, a critical thinking disposition, and the expectation of learning transfer. Methods: This was an experimental study using repeated measures with a nonequivalent control group. The participants were senior nursing students, randomly assigned to experimental (n=30) and control (n=30) groups. The experimental group participated in a nursing education program that included Web-based lectures, pre-briefing, Web-based simulation, and debriefing, whereas the control group’s program included only Web-based lectures. Results: A significant difference was found between the experimental and control groups in problem-solving competency (F=5.84, p=.005), critical thinking disposition (F=4.25, p=.021), and the expectation of learning transfer (t=2.30, p<.025). Also, a significant interaction between time and group was found in problem-solving competency and critical thinking disposition. Conclusion: The results of this study showed that the education program using Web-based simulation positively affected nursing students’ problem-solving competency, critical thinking disposition, and the expectation of learning transfer. Therefore, this program can be considered a valuable aid in educating nursing students.

Essential macleod program (EMP) was used to optimize the transmittance of the transparent conducting layers in an oxidemetal- oxide structure. For EMP simulation, the optical coefficient of the material was extracted using an ellipsometer. Following the simulation studies, oxide-metal-oxide samples were fabricated experimentally, and their optical and electrical properties were analyzed. Multilayer SiInZnO/Ag/Siinzno (S/A/S) structures were grown on glass substrates using radio frequency (RF) and direct current (DC) sputtering at room temperature. Due to the occurrence of destructive interference at the metal and oxide interface, the S/A/S structure exhibited excellent optical properties. As the thickness of the top and bottom oxide layers was increased, the transmittance spectrum was red-shifted due to partial wave interference at the Ag interface. Change in thickness of the top oxide layer had a greater effect on the transmittance than that of the bottom oxide layer. This was due to the difference in refractive index occurring at each interface. Change in Ag thickness shifted the absorption edge in the short wavelength region. Whereas electrical properties, such as sheet resistance and carrier concentration, were found to be dependent on thickness of the sandwiched metal layer. An excellent figure of merit of 63.20 ×10−3Ω−1 was obtained when the thickness of the Ag layer was 11 nm, and the top and bottom oxide layer thickness were 45 and 60 nm, respectively. These values suggest promising optoelectronic properties and are encouraging for future transparent electrode applications.

Purpose: This study aimed to develop a faculty development program for nursing simulation on perceived knowledge, confidence, and competence, and then evaluate its effects. Method: A one-group pretest–posttest design was used. The eight-hour program covered simulation education theory, scenario design and development, simulation design and operation using patient simulators and standardized patients, debriefing, curriculum integration, simulation evaluation, and faculty development. Thirty-eight participants completed a self-administered questionnaire. Data were collected in August 2021. The study used paired t-tests to analyze differences in perceived knowledge, confidence, and competence before and after the application of the program. Results: The participants were generally satisfied with this program. The results indicated that knowledge, confidence, and competence for nursing simulation significantly improved. Conclusion: The faculty development program positively affected simulation instructors’ knowledge, skill, and attitude. Therefore, this validated and standardized training program can be used for training simulation faculty members at universities and institutions. It can not only reduce the cost and effort required for faculty development at each university but also ultimately contribute to the spread of nursing simulation.

Purpose: This study aims to improve nursing students’ competency through evidence-based nursing simulation education. Simulations included blood transfusion care for cancer patients, pneumothorax post-op care, and blood pressure control for hypertension care. Moreover, the study investigated the effects of simulations on anxiety, self-confidence, and student satisfaction with the learning experience. Method: Participants completed a survey on student satisfaction, self-confidence, and anxiety. A prospective, one-group, pre- and post-test design of 135 fourth-grade nursing students was used. A simulation scenario was developed according to the design. It consisted of pre-briefing, practice, serial tests, and debriefing. A simulation of three scenarios comprised blood transfusion care for cancer patients, pneumothorax post-op care, and blood pressure control for hypertension care. Twenty hours of evidence-based nursing simulation practicum consisting of three scenarios dealing with major adult diseases was conducted. Result: Students showed significant improvements over time in self-confidence (t=4.67, p<.001), student satisfaction (t=3.94, p<.001), and anxiety (t=-4.63, p<.001) after the evidence-based nursing simulation. Conclusion: Simulation of evidence-based education may be a useful and effective learning strategy. Nursing educators can design evidence-based simulation programs to improve educational effectiveness.

Purpose: This study aims to investigate the effect of a simulation-based patient safety performance improvement education program on caregivers’ knowledge, attitude, and performance toward safety. Methods: This study adopted a quasi-experimental design that applied before-and-after designs for the test and control groups. It was configured focusing on “infectious disease,” “fires,” “falls,” and “drug abuse.” Results: There was a significant difference in knowledge and patient safety performance between the experimental group and the control group. However, there was no significant difference in attitudes toward safety. Conclusion: The results of this study showed that the simulation-based patient safety performance improvement education program is effective in improving patient safety performance. Therefore, it is necessary to continuously apply and evaluate the simulation-based patient safety performance training program to enable caregivers to develop professional prevention and management capabilities within elderly care facilities

Purpose: Personal protective equipment (PPE) is critical for protecting healthcare workers from COVID-19 outbreaks. Therefore, this study examined the effects of a nursing simulation education program on PPE use for COVID-19 among nursing students. Methods: We employed a non-equivalent control group post-test design. The experimental group (n=38) engaged in a nursing simulation education program on PPE use. The control group (n=36) received PPE and the opportunity to participate in the same program after the intervention. Further, data were analyzed using descriptive statistics and independent t-test. Results: The experimental group showed significant differences in attitude toward PPE (t=3.21, p=.002) and efficacy of PPE use (t=9.92, p<.001), but not in the intention to care for patients with COVID-19 (t=0.95, p=.343). Conclusion: Nursing simulation education for PPE significantly improved attitude and increased self-efficacy toward PPE among nursing students. However, the intention to care for COVID-19 patients was not changed. Thus, it is necessary to find a way to improve the nursing intention toward COVID-19 patients.

Purpose: This study developed an educational program for structured discussion-based learning, problem-based learning (PBL), and simulation for nursing students.

We operated the PBL by applying the structured discussion method and simulation education based on four modules covering major diseases among adults. The data collected before and after the program were analyzed using descriptive statistics and paired t-tests. Results: The program significantly improved nursing students’ learning attitude, problem-solving process, and clinical competence. Conclusions: We verified the effects of the simulation education program for structured discussion-based learning and PBL. Further studies are needed to develop and apply simulation educational programs utilizing various devices that can improve learners’ participation and professors’ operational protocols by systematically combining them with different teaching/learning methods.

Purpose: The purpose of this study was to identify trends in disaster nursing education and conduct a systematic review of the characteristics of simulation-based disaster education programs for nursing students. Method: In May 2020, 12 electronic databases were used to conduct a literature search using Korean and English keywords. Simulation, disaster, nursing, and education were among the search keywords. Fourteen studies were selected. The risk of bias assessment tool for non-randomized studies was used to assess study quality. Results: A total of 14 non-randomized studies were selected. Simulation was mainly conducted using high-fidelity simulators and virtual reality simulations. Disaster scenarios included situations such as a bus crash, earthquake, tornado, and toxic chemical exposure in mass casualty incident nursing or disaster drills. There were differences in the methods of simulation interventions, and we found that disaster related nursing competencies such as disaster knowledge, disaster preparedness, disaster performance, confidence, self-efficacy, and ethical reasoning improved in nursing students after the intervention. Conclusion: Disaster nursing education aims to improve nursing students’ disaster competencies. Future research should examine significant risk of bias control for confounding variables, attrition bias, and outcome evaluation.

More than 90% of students were satisfied with the education program and the simulation education effectiveness was 2.54 on a 3-point Likert scale. Conclusion: The S-PBL program could be useful in clinical nursing education for nursing students seeking to become clinical nurses. It is necessary to develop various S-PBL programs and apply them to the curriculum.

최근 환경규제가 강화됨에 따라 액화천연가스(Liquefied Natural Gas)를 이용하여 전력을 생산해내는 신규발전설비인 부유식 LNG 발전설비(floating LNG power plant)가 개발되고 있다. 부유식 LNG 발전설비는 운용 시 증발가스가 발생하고 이를 제거하거나 회수할 수 있는 시스템의 설계가 필요하다. 그러나 해양플랜트는 해상요건에 따라 설계가 상이하고, 부유식 LNG 발전설비의 설계 전 시행착오를 줄이기 위해 지속적으로 수정이 가능한 BOG 회수시스템 공정모사 모델이 필요하다. 따라서 본 연구에서는 상용공정시뮬레이션 프로그램을 통해 부유식 LNG 발전설비에 적합한 모델을 모델링하고자 냉매사용 유무에 따라 서로 다른 BOG(Boil-Off Gas) 회수시스템을 모델링하여 BOG의 회수율과 액화점을 비교 및 분석하였으며, 그 결과 질소냉매를 사용한 BOG 회수시스템 모델을 부유식 LNG 발전설비용 BOG 회수시스템 모델로 제안하고자 한다.

Purpose: This study aimed to identify the current status and needs of nursing education for extremely low birth weight (ELBW) infants in Korea, and to obtain preliminary information to develop a simulation-based educational program on nursing care for nurses in the neonatal intensive care unit (NICUs). Method: Descriptive survey design was adopted in developing an ELBW infant nursing education program. Data were collected from 71 NICU nurses using a questionnaire survey. Statistical Package for the Social Science (SPSS) (version 23) for windows was used to analyze the frequency, percentage, mean, and standard deviation of the collected data. Results: Seventy-one nurses working in the NICU reported that majority of them (76.1%) had experience in ELBW infants’ nursing education. The following were highly recommended for simulated training by NICU nurses: nursing intervention immediately after birth in ELBW infants (69.0%), NICU‘ initial admission nursing (66.2%), and frequency response coping nursing (57.7%). Conclusion: The study revealed that there is a considerable need for the ELBW infants nursing education program. The results of this survey will ultimately provide a basis for developing simulation-based ELBW infants nursing training programs for NICU nurses.

In this study, we used the 3D simulation program to create bodice patterns for adolescents boy students and analyze the fitting and air gap through 3D simulation. The purpose of this study was to select the bodice pattern method that best suited the body shapes of the adolescents male students. The subjects of this study were the French E pattern, Japanese N pattern, and Korean industrial L and J patterns. The applied size was the sixth Korean human body size survey data of 2010 Korea. The age range of the subjects was 13-18 years. DC Suite Program Ver. 5.1 was used, and SPSS 23.0 program was used for data analysis. As a result of comparing the shapes of the bodice patterns in the 3D simulation program, the E pattern had two waist darts on the front and one shoulder dart and one waist dart on the back, and the J and L patterns only had one dart on the back. The N pattern had no darts on either the front or back. As a result of examining the appearance evaluation of the pattern, air gap, color distribution, and clothing cross-section, the E pattern was evaluated as the closest to the body, and the N pattern was evaluated as the pattern with the largest allowance. The J pattern was evaluated as the best fit for body shape of the male adolescents. However, it is necessary to develop a pattern system by adding extra ease in setting the center front length.
