According to the COVID-19, development of various medical software based on IoT(Internet of Things) was accelerated. Especially, interest in a central software system that can remotely monitor and control ventilators is increasing to solve problems related to the continuous increase in severe COVID-19 patients. Since medical device software is closely related to human life, this study aims to develop central monitoring system that can remotely monitor and control multiple ventilators in compliance with medical device software development standards and to verify performance of system. In addition, to ensure the safety and reliability of this central monitoring system, this study also specifies risk management requirements that can identify hazardous situations and evaluate potential hazards and confirms the implementation of cybersecurity to protect against potential cyber threats, which can have serious consequences for patient safety. As a result, we obtained medical device software manufacturing certificates from MFDS(Ministry of Food and Drug Safety) through technical documents about performance verification, risk management and cybersecurity application.The purpose of this study is to conduct a usability assessment to ensure that ergonomic design has been applied so that the ventilator central monitoring system can improve user satisfaction, efficiency, and safety. The rapid spread of COVID-19, which began in 2019, caused significant damage global medical system. In this situation, the need for a system to monitor multiple patients with ventilators was highlighted as a solution for various problems. Since medical device software is closely related to human life, ensuring their safety and satisfaction is important before their actual deployment in the field. In this study, a total of 21 participants consisting of respiratory staffs conducted usability test according to the use scenarios in the simulated use environment. Nine use scenarios were conducted to derive an average task success rate and opinions on user interface were collected through five-point Likert scale satisfaction evaluation and questionnaire. Participants conducted a total of nine use scenario tasks with an average success rate of 93% and five-point Likert scale satisfaction survey showed a high satisfaction result of 4.7 points on average. Users evaluated that the device would be useful for effectively managing multiple patients with ventilators. However, improvements are required for interfaces associated with task that do not exceed the threshold for task success rate. In addition, even medical devices with sufficient safety and efficiency cannot guarantee absolute safety, so it is suggested to continuously evaluate user feedback even after introducing them to the actual site.

Background: To evaluate the quality of chronic care provided by public health centers located in a South Korean metropolitan city using a modified Assessment of Chronic Illness Care (ACIC). Methods: We conducted self-evaluation surveys and collected data using a modified ACIC from twenty five public health centers. Cultural validity of the original ACIC was examined by the public health and nursing science experts. Based on expert reviews, cognitive interviews, pre-test results, five items of the original ACIC that were not relevant were deleted. The response scale was changed from twelve-point Likert scale to Guttman scale but its scoring system was maintained. Results: Eighty eight percent of public health centers in this study reported that their overall quality of chronic care was at a limited or basic level. About 68% of the centers reported that the organization was as reasonably good or fully developed to provide chronic care. On the other hand, 96% of the public health centers reported that the clinical information system was at a very limited or basic support level. The decision support, the integration of Chronic Care Model components, the delivery system design, the community linkages, and the self-management support were evaluated as limited or basic level of support by more than half of the public health centers, respectively. Conclusion: In a metropolitan area of South Korea, quality of chronic care in public health centers was not found to reach acceptable levels of services. It is critical to enhance the quality of chronic care in public health centers.

Background: To identify the factors that affect the current status and satisfaction of people with disabilities at community oral care centers. Methods: A structured self-administered survey, including five questions on facility environment, five on usage procedure, four on medical skill, four on care cost, three on friendliness, and three on satisfaction, was administered to 218 residents of the G-disabled community care center. It comprised a Likert 5-point scale (strongly agree, 5 points; agree, 4 points; moderate, 3 points; disagree, 2 points; not at all, 1 point). The reliability of the measurement tool was 0.932 for Cronbach's α. Results: The evaluation of community oral care centers for the disabled showed that the environment was hygienic (4.42±0.73), reservation system was well maintained (4.18±0.95), and the dentist-in-charge was satisfied with the treatment (4.37±0.62). The participants agreed that the details were sufficiently explained (4.29±0.71). However, in terms of medical expenses, the score of "have fully heard the explanation of medical expenses and reductions" was 3.88±0.92. The factors affecting satisfaction were sex, final educational background in the facility environment, usage procedure, and medical skill. Conclusion: To increase the satisfaction of people with disabilities at community oral care centers, it is necessary to establish a facility environment and service according to the patients' need and increase the reduction or exemption benefits between different treatment cost categories. Oral health management policies for the disabled should be developed based on these factors, so that the oral care of vulnerable groups in blind spots can be maintained.

The frequency of breast augmentation surgery continues to increase annually; however, the method of follow-up care varies from hospital to hospital. In particular, many different types of post-operative bras are available in the market. This study evaluated the wearing comfort of various commercial bras that were worn immediately after breast enlargement surgery prior to the manufacture of the bra. According to interviews of medical professionals and market research, five types of brassiere were selected and evaluated by wearing satisfaction, functional performance, and an external appearance test for 6 subjects with breast augmentation surgery. The evaluation questionnaires were based on a 5 point Likert scale with data analyzed using SPSS 20.0. The study results revealed that the bra with the highest degree of satisfaction was CNB (without bra cup) type. However, the use of CNB type showed dissatisfaction in functional evaluation questions regarding breast shaking and material & tactile sensation. In the future, it is necessary to develop a new post-operative brassiere based on a CNB type bra that showed the best evaluation. However, it is also necessary to identify the merits of the other four experimental bras and reflect these advantages.
