This study sought to reduce the risk of fractures in elite youth taekwondo athletes to find out the relationship between bone mineral density which are used as indicators of early diagnosis of osteoporosis and cardiorespiratory functional capacity which is an indicator of performance and sports injury the harmful to athletes. The Pearson product-moment correlation was performed to investigate the correlation between bone mineral density, cardiorespiratory functional capacity, and sports injury. The bone mineral density and cardiorespiratory functional capacity, sports injury were examined the relationship using the Simple Linear Regression. The bone mineral density were correlated with the ventilation (r=.388), and VO2max (r=.478). Bone mineral density was correlated with sports injury (r=-.292). When the bone mineral density increased by .002 and .006, the ventilation (p=.001) and VO2max (p=.006) increased by about 1. In addition, when the bone mineral density decline by .016, the sports injury increased by about 1. Improving athletes' bone mineral density can prevent sports injury, and it can be used as a sports injury prevention program in the future.

This study was conducted to identify the effects of repeated cardiopulmonary resuscitation (CPR) training using smart learning on nursing students' knowledge, self-efficacy, and clinical competency. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 102 nursing college students who had received CPR training for 6 months. The CPR training was divided into smart learning, lecture education, and practical education. Data were collected from November to December, 2016 and analyzed by descriptive statistics, ${\chi}^2$-test, t-test and one way ANOVA using the SPSS/WIN 21.0 program. The scores of cardiopulmonary resuscitation knowledge were higher in the lecture education group than the practical education group and the smart learning group. Scheffe's post hoc test revealed a statistically significant difference among groups (F=8.23, p=<.001). The self-efficacy of the practical education group was higher than that of the lecture education group and smart learning group, but this difference was not significant (F=2.46, p=.091). The clinical competency of the practical education group and smart learning group were higher than that of the lecture education group. Scheffe's post hoc test revealed that the value of clinical competency differed significantly among groups (F=59.90, p=<.001). Overall, the results showed that effective education differs based on nursing students' knowledge, self-efficacy, ad clinical competency. Combination training would be required for more effective repeated cardiopulmonary resuscitation training.

In the present study, we investigated and compared the cardiopulmonary and oxidative stress effects of dogs undergoing open and thoracoscopic lung lobectomy. Ten healthy dogs, 5-8 years old, weighing 9-12 kg were used. The animals were randomly assigned to one of two groups according to the type of surgical procedure; open (group 1, n=5) or thoracoscopic lung lobectomy (group 2, n=5). Cardiopulmonary parameters, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) concentrations were measured. There were statistically significant changes in arterial blood gases values in both groups. Total anesthesia and surgical times were significantly shorter in thoracoscopic lobectomy group compared with open surgery group. Increases in plasma SOD and CAT levels, and decreases in GPx levels were observed in both groups after surgery. Significant difference in GPx levels was found when the groups were compared. The GPx level was significantly lower in the thoracoscopic lobectomy group compared with the open surgery group.

Background: Small animal cardiopulmonary bypass (CPB) model would be a valuable tool for investigating path-ophysiological and therapeutic strategies on bypass. The main advantages of a small animal model include the reduced cost and time, and the fact that it does not require a full scale operating environment. However the rat CPB models have a number of technical limitations. Effective maintenance and control of core temperature by a heat exchanger is among them. The purpose of this study is to confirm the effect of rectal temperature maintenance using a heat exchanger of cardioplegia system in cardiopulmonary bypass model for rats. Material and Method: The miniature circuit consisted of a reservoir, heat exchanger, membrane oxygenator, roller pump, and static priming volume was 40 cc, Ten male Sprague-Dawley rats (mean weight 530 gram) were divided into two groups, and heat exchanger (HE) group was subjected to CPB with HE from a cardioplegia system, and control group was subjected to CPB with warm water circulating around the reservoir. Partial CPB was conducted at a flow rate of 40 mg/kg/min for 20 min after venous cannulation (via the internal juglar vein) and arterial cannulation (via the femoral artery). Rectal temperature were measured after anesthetic induction, a ter cannulation, 5, 10, 15, 20 min after CPB. Arterial blood gas with hematocrit was also analysed, 5 and 15 min after CPB. Result: Rectal temperature change differed between the two groups (p<0.01). The temperatures of HE group were well maintained during CPB, whereas control group was under progressive hypothermia, Rectal temperature 20 min after CPB was $36.16{\pm}0.32^{\circ}C$ in the HE group and $34.22{\pm}0.36^{\circ}C$ in the control group. Conclusion: We confirmed the effect of rectal temperature maintenance using a heat exchanger of cardioplegia system in cardiopulmonary bypass model for rats. This model would be a valuable tool for further use in hypothermic CPB experiment in rats.

The purpose of this study is to investigate the effect of wearing clothes, Level B, and Level C PPE on normal CPR using mannequins. The paramedics who participated in this experiment were 20 paramedics with more than 5 years of experience in firefighting area C. It was found that chest compressions in the process that hand off time was 11.9 seconds in the uniform wearing group, 11.4 seconds in the level C PPE wearing group, and 13.1 seconds in the SCBA wearing group. In other words, wearing personal protective equipment prevents the movement of paramedics and uses compensatory movements, which may increase the difficulty of efficient first aid. If this situation persists, it may cause fatigue and damage to the body of paramedics. Rescue and paramedics should wear level personal protective equipment in case of emergencies and conduct rescue and CPR training.

The purpose of this study was to demonstrate the effect on the degree of fatigue and accuracy of cardiopulmonary resuscitation according to the different time delays (3 minutes, 4 minutes). Carrying out repeated measures of variance (repeated ANOVA), we have shown that time effect (F = 7.835, p <.01) and group effect (F = 8.695, p<.01) and the interaction effect between time and group (F = 12.582, p<.001) were all statistically significant. It means, in the test of the main effect of group and time (3 minutes, 4 minutes) using the Bonferroni method, it turned out that the amount of lactic acid of the experimental group was larger than that of the control group (p<.01), and there was no difference until 3 minutes, but the difference of the amount of lactic acid was shown between before the experiment and after 4 minutes, and between 3 minutes and 4 minutes (p <.05), respectively. Then, in the result of the corresponding sample t-test, for comparing the according to the measurement time, the accuracy after 3 minutes became higher than the case of 4 minutes (t = 4.584, p <.001). Therefore, before 119 arrives performing cardiopulmonary resuscitation for emergency, rescuers need to perform cardiopulmonary resuscitation alternating with others before 3 minutes.

In Korea, there are around 30,000 cardiac arrest patients annually. Gradually the number is increasing. Against this background, CPR education and publicity programs were expanded nationwide, but the rate of witness CPR by the general public was 4.4%, which is significantly lower than the 20%~70% rate in other countries. Therefore, in this paper, we analyzed the factors affecting the performance of CPR by witnesses who discovered cardiac arrest patients. Based on the results, an application planning and development study was conducted to provide users with correct cardiorespiratory response tips and step-by-step CPR guidelines to help users effectively assist in increasing the rate of CPR by general eyewitnesses.

This study is to investigate the effect of CPR education on the knowledge, attitude, and self-efficacy of kindergarten, elementary, and secondary teachers. For the study, a total of 176 kindergartens, elementary schools, and secondary school teachers in J province who received CPR education at an Emergency Medical Education Center from March 21 to June 20, 2023 were surveyed. For the collected data, SPSS WIN 20.0 was used to analyze general characteristics, knowledge, attitude, self-efficacy, and educational program effects. As a result of the study, the knowledge score after education (t=-15.93, p<.001), attitude score (t=-5.11, p<.001), self-efficacy score (t=-12.52, p<.001) was significantly increased. After the education by experts, knowledge, attitude, and self-efficacy improved, and it is thought that the increase in knowledge increased attitude and self-efficacy. This is a result proving that the CPR education of the Emergency Medical Education Center was effective. Therefore, it is necessary to find ways for effective CPR education.
