A mock circulatory loop system has been developed to construct a simulator for trainees in cardiopulmonary bypass systems or to simulate a test environment for cardiac-assist devices. This paper proposes a computerized mock circulatory loop system whose node is modularized by using a servo control flow regulator to simulate dynamic change of the hemodynamic status. To observe the effect of time-varying resistance, one with hemodynamic properties, the proposed system replicates the planned cross-sectional areas of the outlet of a ventricular assist device in terms of voltage input of a servo valve. The experiment is performed (1) for steady-input commands of selected area sizes and (2) for dynamic commands such as monotonous increase and decrease, and oscillatory functions of the voltage input, and a computer program based on LabVIEW (National Instruments, Austin, USA) processes every measured data and control command to the servo valve. The results show that the pressure and flow at the target points with respect to time-varying resistance match intuitive estimation: the pressure at the outlet and the pressure drop between both sides of the valve increased and the flow at the outlet decreased for increased resistance.

Purpose: This study aimed to identify the effects of cardiopulmonary resuscitation (CPR) training using a meta-analysis by effect size. Methods: The effect sizes for each variable and the overall effect size for the collected data were identified. The homogeneity verification of the effect size and the difference among the average effect sizes for each mediation variable were determined. Results: The overall average effect size for CPR training was 1.747. Homogeneity verification of the overall effect size was a Q-value of 3716.962, which was statistically significant (p=.000) when${\alpha}=.05$. CPR training showed statistically significant differences depending on age (p=.002), sex (p=.006), number of trainees (p=.000), research design (p=.000), training method (p=.027), and practical training tools (p=.000). Conclusion: CPR training can effectively improve knowledge, skills, and attitudes about CPR. The results of this meta-analysis contribute to the development of more effective educational guidelines for future CPR training and the advancement of the CPR education field.

Purpose: The purpose of this study was to investigate the educational satisfaction of trainees in implementing violence prevention education by workers in the emergency room and insufficient education. Methods: The participants of the study were 65 emergency room employees in S area. Results: First, education was helpful if you actively participated in education, and if you did not actively participate in education, education was shown to be of little or no help (χ²(p)= .000 p-value<.05). Second, formal education (53.3%) was identified as the problem of preventive education currently in place of education, and statistics show that the biggest problem with applying emergency room violence prevention education at worksites is a lack of active support (41.7%) from the police and hospitals. Third, 48.3 percent of the respondents thought that the education methods invited experts were appropriate for emergency room violence prevention education. Conclusion: The problem with the current emergency room violence prevention education is that it is necessary to establish a connection program between hospitals and police stations and give lectures by experts in violence prevention education to apply the contents of the educational curriculum in the workplace with one time and formal education.

Physicians should be able to address health-related issues of patients and populations from a multidimensional perspective. Therefore, medical schools have a social responsibility to develop and implement curricula that enable trainees to acquire the competencies needed to improve all aspects of patient care and healthcare delivery. This study explored the concept of health systems science concept as the third pillar of medical education (the other two are basic science and clinical medicine) in the Korean context, as well as related educational needs. The theoretical foundation of health systems science is the biopsychosocial conceptual model, which emphasizes the biological, psychological, and social factors surrounding patients. We concluded that the three domains (core functional, foundational, linking) and 12 subcategories of health systems science proposed by the Association of American Medical Colleges could be applied to Korean medical education. Health systems science education must be emphasized to solve the various healthcare problems facing Korea today and to train physicians to provide medical services in line with society's needs. Introducing a health systems science curriculum will be challenging in the Korean medical environment, which has traditionally emphasized basic science and clinical medical education. Health systems science education should begin in the basic medical education phase, where physicians' professional identity is formed, and continue through graduate medical education. It is essential to understand related educational needs, develop curricular content, conduct faculty development programs, and provide financial resources for the development of an integrated curriculum.

Competency for practicing gastroenterology in the United States requires accredited training in Internal Medicine, followed by accredited training in gastroenterology and hepatology. The structured training encompasses a 3-year period after graduation with a medical degree for internal medicine, followed by a 3-year period for gastroenterology and hepatology. Within the gastroenterology training period, competency in oncology knowledge and procedural approaches to luminal and solid gastrointestinal organ cancers is required, whereas knowledge competency but not procedural competency is required in areas of advanced endoscopic procedures for cancer care. Only general knowledge, but not competency, is required for areas such as chemotherapy, which can be obtained with further optional training in a structured 2-year oncology fellowship program. Although there is no standardization to date for including full oncology training within a gastroenterology training program in the United States, there is great interest from gastroenterology professional societies to include a pathway for trainees within the gastroenterology training program.

Laparoscopic cholecystectomy is associated with a higher incidence of biliary/vasculobiliary injuries than open cholecystectomy. Anatomical misperception is the most common underlying mechanism of such injuries. Although a number of strategies have been described to prevent these injuries, critical view of safety method of structural identification seems to be the most effective preventive measure. The critical view of safety can be achieved in the majority of cases during laparoscopic cholecystectomy. It is highly recommended by various guidelines. However, its poor understanding and low adoption rates among practicing surgeons have been global problems. Educational intervention and increasing awareness about the critical view of safety can increase its penetration in routine surgical practice. In this article, a technique of achieving critical view of safety during laparoscopic cholecystectomy is described with the aim to enhance its understanding among general surgery trainees and practicing general surgeons.

Mobile computing devices (MCDs), such as smartphones and tablets, are revolutionizing medical practice. These devices are almost universally available and offer a multitude of capabilities, including online features, streaming capabilities, high-quality cameras, and numerous applications. Within the surgical field, MCDs are increasingly being used for simulations. Microsurgery is an expanding field of surgery that presents unique challenges to both trainees and trainers. Simulation-based training and assessment in microsurgery currently play an integral role in the preparation of trainee surgeons in a safe and informative environment. MCDs address these challenges in a novel way by providing valuable adjuncts to microsurgical training, assessment, and clinical practice through low-cost, effective, and widely accessible solutions. Herein, we present a review of the capabilities, accessibility, and relevance of MCDs for technical skills acquisition, training, and clinical microsurgery practice, and consider the possibility of their wider use in the future of microsurgical training and education.

Background Nonliving chickens are commonly used as a microvascular anastomosis training model. However, previous studies have investigated only a few types of vessel, and no study has compared the characteristics of the various vessels. The present study evaluated the anatomic characteristics of various chicken vessels as a training model. Methods Eight vessels-the brachial artery, basilic vein, radial artery, ulnar artery, ischiatic artery and vein, cranial tibial artery, and common dorsal metatarsal artery-were evaluated in 26 fresh chickens and 30 chicken feet for external diameter (ED) and thicknesses of the tunica adventitia and media. The dissection time from skin incision to application of vessel clamps was also measured. Results The EDs of the vessels varied. The ischiatic vein had the largest ED of $2.69{\pm}0.33mm$, followed by the basilic vein ($1.88{\pm}0.36mm$), ischiatic artery ($1.68{\pm}0.24mm$), common dorsal metatarsal artery ($1.23{\pm}0.23mm$), cranial tibial artery ($1.18{\pm}0.19mm$), brachial artery ($1.08{\pm}0.15mm$), ulnar artery ($0.82{\pm}0.13mm$), and radial artery ($0.56{\pm}0.12mm$), and the order of size was consistent across all subjects. Thicknesses of the tunica adventitia and media were also diverse, ranging from $74.09{\pm}19.91{\mu}m$ to $158.66{\pm}40.25{\mu}m$ (adventitia) and from $31.2{\pm}7.13{\mu}m$ to $154.15{\pm}46.48{\mu}m$ (media), respectively. Mean dissection time was <3 minutes for all vessels. Conclusions Our results suggest that nonliving chickens can provide various vessels with different anatomic characteristics, which can allow trainees the choice of an appropriate microvascular anastomosis training model depending on their purpose and skillfulness.
