Purpose: To evaluate undergraduate nursing students' ability in clinical competence, critical thinking, and problem solving following enrollment in a clinical reasoning course. Methods: A clinical reasoning course utilizing a human patient simulator and scenarios was offered to 22 senior students at a College of Nursing in Seoul. Students' clinical competence was measured with a checklist of 15 items by analyzing students' performance recorded on video tapes for eight scenarios. Critical thinking disposition and problem solving were measured by a self-administered questionnaire before and after the course. Data were analyzed using descriptive statistics and Wilcoxon signed-rank test. Results: The high scored items of clinical competence were: 'obtain relevant subjective/objective data', 'interpret vital signs', 'communicate with healthcare providers', and 'utilize standard precautions including handwashing.' Students' critical thinking and problem solving scores following the course were increased with statistical significance. Conclusion: A clinical reasoning course utilizing a human patient simulator creates a realistic clinical environment for nursing students and provides the opportunity to obtain clinical competence, critical thinking, and problem solving skills.

목적 : 모의 치료실에서 환자의 정확한 치료 범위 결정을 위해 이용되는 투시영상은 일부 최신의 고가장비에서는 digital로 capture가 가능하나, 일반적인 simulator에서는 analog영상으로 capture를 할 수 없으며 모니터링만 할 뿐이다. 이번 논제에서는 conventional simulator를 이용한 저가의 Digital image capture system의 구현 방식을 소개하고, capture된 digital 영상을 이용한 임상적인. 실용 증례를 소개하고자 한다. 대상 및 방법 : 본원의 conventional simulator(SIMVIEW NT)용 모니터의 비디오 단자(terminal)에 video signal cable을 연결하여 A/D converter에 연결한다. converter jack을 컴퓨터 capture boar에 연결하고 컴퓨터상의 image capture system을 작동시켜서 원하는 image를 capture하거나 동영상을 녹화한다. Esophagus, cervix, breast 환자 등의 capture image를 상용화된 image processing program을 통해 임상적으로 활용한다. 결과 : 경제적으로 저렴하고 용이한 방법으로 Digital image capture system(DICS)의 구축이 가능하였으며 capture된 영상을 이용하여 simulation시에는 보다 정확한 환자 정보와 치료범위를 결정하는데 도움이 되었고, capture된 영상은 data로써 충분한 가치가 있었다. 결론 : 고가의 상용화된 장비를 구입하기 어려운 경우에 이와 같은 방법으로 저가의 system를 구축하게 되면 경제적 효과와 더불어 고가장비와 동등한 영상의 획득 할 수 있으며, 그러한 과정을 통해 얻어진 영상을 이용하여 다른 software program과 연계한다면 더 많은 임상적인 연구를 할 수 있을 것이라 생각된다.

Blood pressure is one of the important vital signs for monitoring the medical condition of a patient. Automated NIBP(non-invasive blood pressure) monitoring devices calculate systolic and diastolic blood pressures from the oscillation in cuff pressure caused by a pulsation of an artery. To validate the NIBP devices, we developed a simulator to supply the oscillometric waveforms obtained from human subjects. The simulator provided pressure pulses to device-under-test and device readings were compared to the auscultatory references. Fully automated simulation system including OCR(optical character recognition) were developed and used for NIBP monitoring devices. The validation results using the simulator agreed well with previous clinical validation. More validation studies using the standardized oscillometric waveforms would be required for the replacement of clinical trials to validate a new automated NIBP monitoring device.

Purpose: This study was conducted to investigate the effects of an education program using a high-fidelity simulator of labor and delivery on nursing knowledge, critical thinking, and clinical performance among nursing students who had not yet experienced clinical practicum. Methods: The development of a 5-week maternity nursing education programs using high-fidelity simulators included modules containing case-oriented scenarios, knowledge, and skills required for maternity care. A randomized controlled study was conducted to verify the effects of the developed program. Data were collected from October 21 to December 9, 2019. The experimental group (n=36) participated in a 5-week high-fidelity simulation program on care for the woman in labor, whereas the control group (n=36) received standard education as lecture and practice with delivery model. The collected data were analyzed using descriptive statistics (frequency, percentage, mean, and standard deviation), the Chi-square test, Fisher exact test, and t-test. Results: For participants who received education using the high-fidelity simulation program, nursing knowledge (t=2.33, p=.011), critical thinking (t=3.73, p<.001), and clinical performance (t=2.53, p=.006) were significantly higher than in the control group. Conclusion: Even for students with no clinical experience, high-fidelity simulation-based nursing education was effective in improving nursing knowledge, critical thinking, and clinical performance among nursing students. Nurse educators will be able to use this high-fidelity simulator effectively, especially in situations where direct clinical practicum may not be feasible.
