본 논문은 의료 영상 검색 시스템에서 뇌 MRI 이미지 데이터베이스에서 사용자의 질의를 만족하는 질의 결과 집합에 대한 시각화 방안을 제안한다. 한 환자의 뇌 MRI 이미지를 검색 결과로 제시할 경우 종류별, 방향별로 다양하고 여러 환자의 경우에는 그 양이 더욱 방대해진다. 이러한 뇌 MRI 이미지를 공간 제약적인 화면에 표현하는데는 한계가 있다. 따라서 본 논문에서는 질의 결과를 제시할 대 유사도가 높은 순서로 나열하고, 사용자 요구에 따른 관련 이미지를 종류와 방향별로 제시하여 이미지 조작을 가능하게 한다. 도한, 제시된 뇌 MRI 이미지를 효율적으로 브라우징할 수 있도록 3차원 블록 메타포어를 이용한 시각화 인터페이스를 통하여 공간 활용도의 향상과 사용자 인터페이스의 편의성 및 인지도를 증진한다.

In this study, we investigated whether the degree of anxiety, depression, stress, and ego resilience in the COVID-19 epidemic situation could affect the quality of life of college students and analyzed the correlation between them. In addition, the causal relationship and mediating effect on ego resilience, stress and quality of life were analyzed and necessary countermeasures were proposed. As a result of analyzing the correlation between each variable, it was found that anxiety, depression, stress, quality of life, and self-resilience all had significant correlations. In particular, stress was found to play a complete mediating role in the effect of ego resilience on quality of life. It is expected that this study will be used as a basis for research on the effect of stress and self-resilience on the improvement of quality of life in the Corona situation.

The purpose of this study was to investigate the potential causal relationship between unmet healthcare needs and metrics related to quality of life. To examine the relationships between these variables, the study conducted an analysis by processing additional irradiated raw materials of the Korean Medical Panel. The metrics related to quality of life included six variables: athletic ability, self-care, daily activities, pain/trouble, uneasiness/depression, and subjective health conditions. Linear regression analysis revealed that the unmet healthcare needs had statistically significant negative effects on all six quality of life variables. A review of the magnitude of the linear regression β values for those variables showed that the relative level of influence on the quality of life variables decreased in the following order: pain/trouble, subjective health conditions, uneasiness/depression, daily activities, athletic ability, and self-care. Based on the results, practical applications related to strengthening working-level links between health and welfare is considered an effective policy response to the continued presence of unmet healthcare needs; such applications could contribute to improving the quality of life of those with unmet healthcare needs.

Background: This study investigates improvements in non-value-added nursing activities in clinical work, in order to improve the efficiency and quality of nursing activities. Methods: The study was performed as a quality improvement project at a tertiary general hospital. The nursing activities that needed improvements were categories into admission care, discharge care, supply management, diagnostic work-up related activities, and others. The nursing time and frequency of non-value-added activities were compared across nine nursing units before and after implementation of the quality improvement program. Post-implementation patient and nurse satisfaction were subsequently analyzed. Result: Post-implementation, the time spent on non-value-added nursing activities was reduced and patients and nurses were satisfied with the improvements. Discussion: Reducing non-value-added activities in nursing can increase the work efficiency and ensure time for patient care, thus improving the quality of nursing care. For further study, accurate surveys on nursing activities based on nursing time are required.

Purpose: The purpose of this study was to determine the effect of simulation evacuation training improvement activity through wheelchair skill training. Methods: The study included 40 patients with early stroke who were randomly allocated to a wheelchair skill training group (Experimental group, n=20) and a general exercise group (Control group, n=20). Both groups performed the exercise 3 times a week for 3 weeks. Outcomes were assessed using Wheelchair Skills Test Skills Performance (WSTSP), Wheelchair Skills Test Skills Safety (WSTSS) and Wheelchair Propulsion Velocity (WPV). Results: After 3 weeks of training, both groups showed significantly improved WSTSP, WSTSS and WPV (p<.01 in both groups). However, the WSTSP, WSTSS and WPV in the experimental group were very significantly better than in the control group (p<.01). Conclusion: These findings indicate that wheelchair skill training may be effective at improving wheelchair skill ability and wheelchair propulsion velocity in stroke patients who cannot walk independently. Therefore, short-term wheelchair skill training could be useful for patient safety in simulated evacuation situations.

The objective of this study was to analyze the effect of characteristics of maritime telemedicine (service quality, recognition or not of service, health counselling service experience or not) on seafarer's satisfaction, and also analyze the effect of seafarer's satisfaction on loyalty. This study's data was collected from the Research Report of Survey of telemedicine service subjects in 2017 conducted in the maritime telemedicine pilot project. However, only 103 seafarers who received maritime telemedicine (Tele-Monitering) services were analyzed statistically. The main results of this study were as follows. ⅰ) Better service quality led to higher levels of satisfaction, ii) High levels of seafarer's satisfaction led to high levels of loyalty, iii) Seafarers whose age is under 50 than 30 years old are less satisfied, ⅳ) In total boarding career, Seafarers with more than 5 years but less than 10 years were more satisfied than seafarers with less than 5 years, ⅴ) Seafarers with more than 10 years but less than 15 years were more satisfied than seafarers with less than 5 years, ⅵ) Seafarers with more than 15 years but less than 20 years were more satisfied than seafarers with less than 5 years, ⅶ) Also, Seafarers in excess of 20 years were more satisfied than seafarers with less than 5 years, In conclusion, ⅰ) Better service quality led to higher levels of satisfaction and loyalty. Accordingly, the improvement of service quality is not only an important factor in improving satisfaction and loyalty, but also plays an important role in forming a positive image of maritime telemedicine. ⅱ) Seafarers with younger age and lower overall total boarding career were more satisfied. It is believed that the seafarer who are willing to use telemedicine and who are willing to refer to others are young.

Purpose: This study was to examine whether a health care model that provides comprehensive medical services based on population groups to members of the medical cooperative is applicable as a policy alternative in terms of medical use and cost. Methods: Data were derived from National Health Insurance claim data in 2019. We compared the medical volume and expenses of patients who visited social cooperative-type medical clinics with other patients, control group who visited other clinics in a local area. Results: The average number of visit days was 25.3 days in social cooperative-type medical clinics, more than 24.2 days in the control group (p=.004). However, the average medical cost per visit was KRW 46 thousand in social cooperative-type medical clinics, which was significantly lower than KRW 51 thousand in the control group (p<.001), and the total medical cost was also KRW 16.1 billion in social cooperative-type medical clinics and KRW 16.9 billion in the control group. Conclusion: We identified that a population-based health care model might change patients' behaviors to health care services and decrease total medical cost. Further population based experiment is needed to develop alternative healthcare model.

Purpose: This study aimed to identify the characteristics of patient safety incidents (PSIs) related to nursing and to provide primary data for preventing the recurrence of similar incidents. Methods: This secondary analysis study included damage claims rulings filed for clinical negligence from 2014 to 2018 that contained the keyword 'nurse'. It excluded judgments irrelevant to nursing care and in which clinical negligence or causal damages were overruled. A total of 93 cases were analyzed. The characteristics of PSIs were derived through descriptive statistics, and two instances of nursing-related PSIs were examined by qualitative content analysis focusing on root causes. Results: The analysis of PSIs related to nursing suggested that the medical institutions where the PSIs occurred most frequently were hospitals, and the most common types of PSIs were medication, surgery, and treatment/procedure, in that order. In addition, it indicated that nursing-related PSIs occurred most frequently in general wards during the day shift, with the most common related nursing practice being managing potential risk factors. The qualitative analysis showed that careless monitoring and institutional inertia were causes of PSIs. Conclusion: To prevent nursing-related PSIs, nurses need to individually monitor and assess patient conditions. In addition, support should be accompanied by the improvement in the systems in place aimed at preventing the recurrence of nursing-related PSIs at the institutional and national level, such as securing appropriate nursing personnel and improving labor conditions.
