Purpose: This study investigated the effects of simulation-based nursing education (for the care of congestive heart failure patients) on self-directed learning competency, clinical knowledge and problem-solving ability among nursing students. Methods: A one-group, pre-post design was utilized with 87 nursing students as the subjects. The scenario of simulation-based nursing education was created using a high-fidelity patient stimulator, and consisted of four states ((1) assessment, (2) reviewing laboratory data and administering medications and treatments, (3) managing increased dyspnea and decreased urine output, and (4) handling the "getting better" state). The simulation-based nursing education included orientation, team-based learning, team-based practice, and debriefing. The data were analyzed using descriptive statistics, Pearson's correlation coefficients and paired t-tests. Results: The scores on the factors for self-directed learning competency (t=-2.57, p= .011), clinical knowledge (t=-6.85, p<.001), and problem-solving ability (t=-3.01, p= .003) increased significantly after the education intervention. Conclusion: Simulation-based nursing education is useful in improving self-directed learning competency, clinical knowledge, and problem-solving ability in nursing students.

Recently, the methods that measure and analyze brain electrical activity quantitatively have been available with the rapid development of computer technology. The quantitative electroencephalography(QEEG) is a method of computer-assisted analyzing brain electrical activity. The QEEG allows for a more sensitive, precise and reproducible examination of EEG data than that can be accomplished by conventional EEG. It is possible to compare various EEG parameters each other by using QEEG. Neurometrics, a kind of the quantitative EEG. is to compare EEG characteristics of the patient with normative data to determine in what way the patient's EEG deviates from normality and to discriminate among psychiatric disorders. Nowadays, QEEG is far superior to conventional EEG in its detection of abnormality and in its usefulness in psychiatric differential diagnosis. The abnormal findings of QEEG in various psychiatric disorders are also discussed.

Purpose: The purpose of this study was to identify patient safety awareness and emergency response ability and affecting factors perceived by nursing homes and home visiting caregivers. Methods: This study was a descriptive study that conveniently extracts nursing caregivers who care for elderly patients in S and G provinces, Korea. Data collection was done by structural questionnaires from April to May 2018. A total of 204 responses consisting of 103 nursing homes and 101 home visiting caregivers were used for data analysis in SPSS Win 22.0. Results: Patient safety awareness and emergency response ability of nursing homes caregivers with each $4.24{\pm}0.50$, $74.26{\pm}09.57$ was each higher than that of the home visiting caregivers with $3.68{\pm}0.49$, $68.02{\pm}12.12$ (p<.001). The affecting factors of the patient safety awareness were working place, safety education, and daily average working hours with 12 or more (F = 27.30, p<.001) and that of emergency response ability were number of patients per personnel with 9 or more and emergency situation experience (F=14.00, p<.001). Conclusion: These results suggest that it is necessary to develop a safety education program that can share indirectly experience emergency situations that occur on the job site.

Purpose: The purpose of this study was to understand the perception of medical staff to propose an infected patient transport robot as a means of responding to infectious diseases. Methods: The data collected through the survey was analyzed through AHP analysis. The measurement tools used in this study were derived through the SERVQUAL model and Focus Group Interview(FGI), and consisted of four detailed questions for each of five classes: tangible, reliability, responsiveness, assurance, and empathy. Results: As a result of the study, there are concerns about risk factors that may occur in areas where medical staff intervention is minimized. Above all, we confirmed the consensus that safety should be the top priority during the process of robots to transport patients. In particular, highlighted were the resolution of device errors that may occur during the process for transporting patients and easy provision of the first aid. Additionally, the ability to monitor patients and suppress infection factors turned out to be important, which was directly related to the simplification of the role of medical staff and work efficiency. Conclusion: As one of the means of effectively controlling infectious diseases in a pandemic situation, a robot to transport the infected patient was considered. However, in order to commercialize this, specific verification of the safety of medical staff and patients is needed, and empirical data on providing the first aid, patient monitoring, and infection factor suppression should be presented.

In this paper, we aims to develop a microcontroll er-based ECG monitoring system and portable pulse oximeter using Compact Flash Interface. First, portable pulse oximeter system is designed to record 2 channel of biosignals simultaneously, including 1 channel of $SpO_2$ and 1 channel of pulse rate. It is very small and portable. Besides, the system makes it possible to measure a patient's condition without an additional medical equipment. We tried to solve the problems generated by a patient's motion. That is, we added an analog circuit to a traditional pulse oximeter in order to eliminate the change of the base line. And we used 2D sector algorithm. As present, SpO2 modules are completed. But there are still many further development needed in order to enhance the function. Especially, compact falsh interface remains the most to complete. Second, ECG monitoring system uses almost same as present 3-lead ECG system. But we focus on the analog part, especially in filter. The proposed filter is composed of two parts. One is a filter to remove the power-line interface. The other is a filter to remove the baseline drift. A filter to remove the power-line and the baseline drift is necessarily used in the ECG system. The implemented filter have three features; minimizing the distortion in DC component, removing the harmonic component of power-line frequency. Using compact flash interface, we can easily transfer a patient's personal information and the measured signal data to a network based server environment. That means, it is possible to implement a patient's monitoring system with low cost.
