Purpose: The purpose of this study was to develop a scenario and evaluate the performance of paramedic students in head trauma simulation education. Method: This study selected a refined head trauma scenario that was developed by graduate students during class from september to November, 2010. Evaluation on implementation of head trauma simulation was conducted on seventeen paramedic students divided into four groups during November, 2010. Results: 1. The head trauma scenario was developed according to the patient assessment for approximately 10 minutes. It contained scene size-up, initial assessment and intervention, rapid trauma assessment and intervention, and decision of transfer. 2. The average time turned out to be 9 min and 36 sec after simulation learning. Total mean score in simulation performance was 2.20, the highest score was 2.44 in initial assessment and intervention, and the lowest score was 1.5 in decision of transfer. 3. Confidence mean was high with the score of 1.0. Conclusion: The finding of this study demonstrate that the simulation education can improve problem-solving ability and critical thinking, and increase the confidence in prehospital emergency care; therefore, simulation may be the new effective paramedic education strategy and simulation learning is needed for further development of various scenarios.

Objective: This study was carried out to examine factors influencing job stress and health promotion behavior of medical doctors, who play the important role for improving people's health. The data were collected from 340 medical doctors working in clinic and hospitals in Daegu using self-administered questionnaires over the period from July 1 to August 15, 2018. Methods: A multiple regression model was used to study the factors influencing job stress and health promotion behavior of medical doctors. Results: This study showed that average job stress level of the subjects was 3.06 out of 5 point. The medical doctors with carrying out surgery and longer working time tend to have higher job stress level compared to other groups without surgery and having short working time. And medical doctors generally do not have good health promotion behavior and average level of practice of health promotion behavior of the subjects was 2.30 out of 5. The groups with high rate of quitting job and working in hospital tend to have lower practice level of health promotion behavior compared to other groups. And it also showed that the groups with higher the job satisfaction rate and vocational aptitude tended to have the higher level of practice of health promotion behavior compared with other groups. Conclusions: Medical doctors tend to have higher job stress level, whereas they have relatively lower health promotion behavior compared with people with other jobs. Thus, strengthening of health education and counselling for medical doctors and improvement of work environment considering job's characteristics is needed. In particular, the education for job stress management and health promotion in regular continuing education program organized by medical doctors's association should be strengthened.

Systems thinking, a linking domain of health systems science (HSS), is an approach that investigates specific problems from a holistic perspective. It supports improving patients' health, fulfilling their health needs, and anticipating issues that threaten patient safety within the healthcare system. It also helps solve problems through critical thinking and ref lection. This study aimed to develop an curriculum on systems thinking, explore the effectiveness of the course, and investigate the applicability of HSS education at individual universities. In this study, the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model was utilized to design, develop, implement, and evaluate an elective course on systems thinking. In the design process, learning outcomes and goals were developed, and educational content, teaching-learning methods, and student evaluation methods were linked. In the development process, class materials and evaluation materials were prepared. In the implementation process, the course was implemented, and the evaluation process analyzed the results of learning performance and curriculum assessments. The evaluation found the following results. First, the students in the study realized the importance of systems thinking and experienced the need for systems thinking through non-medical and medical situations. Second, the students were very satisfied with the learning activities in the course (mean=4.84), and the results of the self-competence evaluation, conducted before and after the course, also showed a significant improvement. This study confirmed the effectiveness of the elective course, and its results can serve as a reference for developing an HSS curriculum.

Purpose: The aim of this study was to compare dementia awareness among physiotherapists and occupational therapists who treat dementia patients and provide opportunities to increase dementia awareness as medical technicians, expand the scope of treatment, and enhance professionalism. Methods: An online survey was conducted from January 8th to 19th, 2021 for physical therapists who are members of the Korean Physical Therapist Association and Occupational therapists who are members of the Korean Occupational Therapists Association. The collected data were analyzed using the SPSS 21.0 program. To verify the difference in the awareness of dementia among medical technicians, a t-test was performed, and the chi-square test was used to analyze the difference in the responses for each question. Results: In this study, occupational therapists had a significantly higher average and standard deviation than physical therapists. Occupational therapists also had a significantly higher level of dementia awareness, including dementia symptom-related, dementia disease-related, and dementia therapy knowledge. Conclusion: The results of this study indicate that various educational initiatives and systems should be developed to help medical professionals increase their awareness and interest on dementia as a community, which can enable them to move in the same treatment direction with a common goal.

Ceramide is the most abundant lipid in the epidermis and plays a critical role in maintaining epidermal barrier function. Overall ceramide content in keratinocyte increases in parallel with differentiation, which is initiated by supplementation of calcium and/or vitamin C. However, the role of metabolic enzymes responsible for ceramide generation in response to vitamin C is still unclear. Here, we investigated whether vitamin C alters epidermal ceramide content by regulating the expression and/or activity of its metabolic enzymes. When human keratinocytes were grown in 1.2 mM calcium with vitamin C ($50{\mu}g/ml$) for 11 days, bulk ceramide content significantly increased in conjunction with terminal differentiation of keratinocytes as compared to vehicle controls (1.2 mM calcium alone). Synthesis of the ceramide fractions was enhanced by increased de novo ceramide synthesis pathway via serine palmitoyltransferase and ceramide synthase activations. Moreover, sphingosine-1-phosphate (S1P) hydrolysis pathway by action of S1P phosphatase was also stimulated by vitamin C supplementation, contributing, in part, to enhanced ceramide production. However, activity of sphingomyelinase, a hydrolase enzyme that converts sphingomyelin to ceramide, remained unaltered. Taken together, we demonstrate that vitamin C stimulates ceramide production in keratinocytes by modulating ceramide metabolicrelated enzymes, and as a result, could improve overall epidermal barrier function.

Background Candidate characteristics for hand surgery fellowship training remains unknown, as very little data is available in the literature. This study aims to provide information on the criteria that are employed to select candidates for the hand surgery fellowship match. Methods A 38-question survey was sent in April 2015 to all Accreditation Council for Graduate Medical Education recognized hand surgery fellowship program directors (n=81) involved in the U.S. match. The survey investigated factors used for the selection of applicants, including medical school, residency training, research experience, fellowship interview, and candidate characteristics. A 5-point Likert scale was used to grade 33 factors from "not at all important" (1) to "essential in making my decision" (5); or for five controversial factors from "very negative impact" (1) to "very positive impact in making my decision" (5). Results A total of 52% (42 out of 81) of responses were received from hand surgery fellowship program directors. The most important influential factors were interactions with faculty during interview and visit ($4.6{\pm}0.6$), interpersonal skills ($4.6{\pm}0.5$), overall interview performance in the selection process ($4.6{\pm}0.6$), professionalism and ethics ($4.6{\pm}0.7$), and letters of recommendation from hand surgeons ($4.5{\pm}0.7$). Factors that have a negative impact on the selection process include visa requirement ($2.1{\pm}1.2$), graduate of non-plastic surgery residency program ($2.4{\pm}1.3$), and graduate of a foreign medical school ($2.4{\pm}1.1$). Conclusions This study provides data on hand surgery fellowship directors' perception on the criteria important for fellowship applicant selection, and showed that interview-related criteria and letters of recommendation are the important factors.

Background: This study purposed to compare the difference on medical utilization and health expenditure of baby boomer generation by depression between gender. Methods: Korea Welfare Panel Survey 2016, provided by the Korea Institute for Health and Social Affairs, was used for the analysis. For the research, we used the two-part model, yes or no of use (part 1), and frequency of use (part 2) for medical utilization. The dependent variables are the whether or not to use of hospitalization services, outpatient services, length of stay, outpatient service visits, and health expenditure. And the independent variables are used as the predisposing (education, spouse presence), enabling (insurance type, private insurance, economic activity, income), and need (chronic disease, self-rated health, disability) factors in the Andersen behavior model. Depression was used as intervening variables. Structural equation model and multiple group analysis by gender were used. Results: There were differences in the medical care usage and cost between men and women in baby boomer. For men, mediating effects of depression were present at the hospitalization (yes/no), length of stay, and health expenditure. On the other hand, for women, the mediating effect of depression was found only at the outpatient visits. Specially, depression was working at the medical services by the different way between gender. The size of effect (multiple group analysis) was affected by significant differences between men and women. Conclusion: This study found that the mediating effect of depression is increased medical usage and health expenditure and the effect factors are different by gender. Therefore, it is necessary to establish a medical care policy considering the socio-economic characteristics of baby boomers.

Virtual Reality (VR) is one of the core components of the fourth industrial revolution as a technology that makes the virtual world feel as if it is real. VR is being used in various fields such as entertainment, advertisement, education, medical care, training, sports, and tourism, as well as providing contents for such things as games and videos. Libraries are already looking for ways to utilize VR from various angles, such as operating experiential programs. The purpose of this thesis is to develop and propose a VR-based library user education program. In order to achieve the purpose of the study, we analyzed previous studies from a theoretical perspective to find a way to construct a user education program, and also to derive possible implications based on examples of countries such as the United States and Korea that are already introducing and applying VR technology to library services. Therefore, the user education program proposed in this study can be used as a basic building block when many libraries want to develop VR-based programs in the future.
