Purpose: The aim of this study was to provide basic data to improve the survival rate of pre-hospital cardiac arrest patients. This study suggests a more effective method of performing effective chest compressions for a cardiac arrest patient in a moving ambulance. Methods: To compare the differences between gender and license (qualification), SPSS 18.0 (Windows) was used. Independent and paired t-tests were used for differences between before and after wearing a rescuer's belt. Results: The success rate of chest compressions according to gender was higher in males ($68{\pm}21.91%$) than in females ($25.04{\pm}16.88%$). There was no difference according to license ($44.70{\pm}26.63$ for paramedic, $45.05{\pm}19.25$ for nurse). However, the depth (mm) and the success rate (%) were improved during the evaluation of chest compressions when wearing the rescuer's belt (depth: $46.95{\pm}6.49$ vs. $49.55{\pm}6.05$, success rate: $44.80{\pm}24.66$ vs. $57.39{\pm}26.823$). Conclusion: Wearing a rescuer's belt in an ambulance during patient transport can result in deeper and more accurate chest compressions; therefore, it is expected to be effective in recovering the circulation of patient with cardiac arrest.
Purpose: The study aims to provide basic data for understanding the department of paramedicines' bachelor's degree courses to enable curriculum development and reorganization. Methods: The 2023 academic curricula for all eleven universities with active departments of paramedicine offering bachelor's degrees were investigated from April 25 to May 10, 2023. Results: The average courseload was 22.0 units. There were 7.73 major subjects, with 19.45 units on average. The culture subject was available in 7 colleges and was 2.55 units on the average 1.18 subject. Grouping the major subjects showed that 15.3% of subjects were related to advanced paramedicine (the most common course), followed by 11.8% related to research methodology and seminar, and 10.8% related to radiology and simulations. Related subjects in statistics, disaster, and forensic science were also offered. Conclusion: This study found that the curricula of the departments of paramedicine differed from that of the general bachelor's degree. Going forward, university leaders should organize the paramedicine curriculum considering the environmental changes in emergency medicine and the scalability of EMT-Paramedic jobs.
Purpose: The purpose of this study is to examine the EMT student's attitude to the disabled and provide the basic materials of educational program to make them have right awareness and attitude of the disabled. Methods: The subjects of this study were 348 of 339 emergency medical students at three departments of emergency medical in G metropolitan city who gave consent to take part in the research and the data were collected for 10 days from Mar. 2 to 11, 2011. It used DFS (Disability Factor Scale) developed by Siller (1967) and revised and complemented by Lee Jong Nam (1997) after validity and reliability test. Data collected were analyzed with technical statistics, t-test and ANOVA using SPSS/ PC 12.0 Results: The results of this study are summarized as follows. 1. On the question that there are the disabled around the subjects, 74.7% of the respondents answered 'none', and on the question of having concerns on the disabled problems, 61.5% of the respondents answered 'they have no concerns on them'. In addition, on the question of effective methods for improving a negative awareness of the disabled, many of subjects responded the governmental support must be a priority. 2. The subjects' attitude to the disabled scored average 3.13 and they have positive attitude to the disabled. In six sub-areas of attitude to the disabled, tension in contact with the disabled scored 2.90, inferred emotional disorder 2.79, unconditional repulsion 2.78, refusal to friendly relation 2.74, limitation of other functions undamaged 2.66 and distorted identification 2.65. 3. Variable showing a significant difference in the results of analysis according to general characteristics of subjects was age and those who are over '21' showed more positive attitude to the disabled than those who are below '20'. 4. In the results of analysis according to the subjects' disability related characteristics, those who have the disabled in their friends or family and have concerns on the disabled problems have a positive attitude to the disabled. Promotion and education through mass communication for changing the awareness of the disabled into a positive attitude will be most effective. Conclusion: Consequently, positive attitude of EMT student's to the disabled can be fostered by continuous contact with the disabled and their participation in voluntary services in the dimension of individual or school will be important and also the various practical methods such as enlightenment movement and supply of right information through mass communication should be sought.
Purpose : The purpose of this study was to supply basic data for the impact on the accuracy of basic CPR according to position and foot-board height of basic CPR provider. Methods : Study design was within - group design. Subjects were 25 EMT-P Students in K city. Interventions was basic CPR performed on a resuscitation manikin placed on a hospital bed, kneeling on the bed adjacent to the manikin. Data was analyzed using descriptive statistics and Friedman test. Results : In case of the basic CPR performed on a resuscitation manikin placed on a hospital bed, ventilation accuracy was the highest in less than 160 cm height, foot-board height : $34.2{\pm}1.48cm$, 91.4% and in 161-165 cm height, foot-board height : $26.0{\pm}2.14cm$, 88.4% and in 171-175 cm height, foot-board height : $23.0{\pm}1.41cm$, 91.3% and in the above 176 cm, kneeling on the bed, 95%. Chest compression accuracy was the highest in less than 160 cm height, foot-board height : $30.2{\pm}1.48cm$, 95.6% and in 161-165 cm height, kneeling on the bed, 97.6% and in 171-175 cm height, kneeling on the bed, 98.5% and in the above 176 cm, kneeling on the bed, 98.7% and foot-board height : $20.5{\pm}1.91cm$, 98.7%. Chest compression error was due to too weak : 2.0-35.4 times. There were ststistically significant differences in 191-195 cm group according to chest compression mean depths($x^2=10.824$, p = .013) and chest compression error (p = .040).

Purpose : This is a study on the actual state of instructing in cardiopulmonary resuscitation(CPR) in hospitals, so lays its purpose on providing basic materials for instructing in CPR by understanding the actual state of instruction in CPR for paramedics or first aide persons in hospitals. Result : 1. As a result of examining the actual state of instruction in CPR operation during the past 3 months, 89.3% of the subjects answered that they receive regular instruction. 2. As the number of CPR instruction during one year, the majority of them, 96.0% answered that they have instruction more than one time a year. 3. As answers to their desired first-aid instruction to receive by allowing duplicated responses with 4 items, instruction in CPR and respiratory obstruction for adults was 18.2% occupying the highest proportion followed by instruction in first-aide treatment for traumas with 17.7% and in how to use the AED with 16.3%. Suggestion : First, it is thought that instruction in CPR should be conducted on a continuous basis and the number of instruction should increase. Second, one should provide first-aide persons with proper instruction in CPR operation by developing time tables and protocols for instructional programs, and also make it possible that they can learn various skills by increasing the number of instruction.
Purpose: There has been an increase in the number of prehospital cardiac arrests due to the increasing number of cardiovascular diseases and the increase in the average age of the population. We performed this study to identify the proper resuscitation technique and AED to be used to increase the survival rate in prehospital cardiac arrests. Methods: This studied 159 victims with prehospital cardiac arrests(VF or VT rhythm) by EMT's Reports from January to August, 2005. Results: 108 of 159 victims(67.9%) were shocked by AED. Eighty of 159 victims(50.9%) were recorded with AED shock in prehospital cardiac arrests. A number of shocks is averaged 2.19; 46.2% of one-shock and 86.1% of 1-3 shock. EMS first-tier response interval from time of dispatch to scene arrival was 5.88 minutes, from scene arrival to scene start was 7.36 minutes, from scene start to hospital admission was 9.91 minutes and from scene arrival to AED shock was 6.84 minutes. EMT provided advanced care to prehospital cardiac arrests: 97.5% in CPR, 10.1% in advanced airway management, 67.9% in AED shock. Conclusion: With the increase in cardiovascular disease and old age, the number of prehospital cardiac arrests has risen gradually. However, there were lack of CPR by bystander, defibrillation and advanced cardiac life support(ACLS) in prehospital stage. To improve the adequacy of basic life support and to increase the performance of ACLS, especially AED, we must create challenges to develop new protocols in prehospital care.
Purpose : This study compared before and after emergency patient evaluation education of the 1st graders at the department emergency medical technology(EMT) students, and analyzed its effects on patient evaluation ability after education. The aims of this study was to develop effective educational program and to provide basic materials for its educational method. Methods : This study was carried out by 66 first graders attending the department of emergency medical technology(EMT) at a college in G province and data were collected from Apr. 1 to 2, 2009. The questionnaire consisted of knowledge of emergent patient evaluation, academic self-efficacy, and technical performance after emergent patient evaluation education. We analyzed the influence of knowledge and academic self-efficacy on accurate technical performance with SPSS 14.0 version. Results : 1. In knowledge score, it was 9.27 before education and increased to 35.19 after education and that there was statistically significant difference. In academic self-efficacy, task difficulty preference scored 2.73 before education and 3.97 after education, self-control efficacy scored 2.84 before education and 4.05 after education, self-confidence scored 2.45 before education and 4.21 after education. There were statistically significant increases after education. Technical performance scored 0.00 before education, but it scored 18.78 after education and there was statistically significant increase after education. 2. In sex as one of general characteristics, self-confidence which was sub-factor of academic self-efficacy scored higher in male students(4.28) than in female students(4.10). There was statistically significant difference(p < 0.05). 3. Knowledge had positive correlation with self-control efficacy which was the sub-factor of academic self-efficacy(r = 0.249, p < 0.05) and self-confidence which is the sub-factor of academic self-efficacy had the positive correlation with technical performance(r = 0.258, p < 0.05). 4. Self-confidence which was the sub-factor of academic self-efficacy(B = 0.372, p < 0.05) had statistically significant influence on technical performance. ability of self-confidence to explain technical performance(R2) was 11.10%. Conclusion : From the results of this study, it is necessary that EMT students should learn professional first aid, accurate patient evaluation through self-efficacy development.

This study investigated to provide basic data for infection control education on new infectious diseases by confirming the level of knowledge, training status, stress, and need for training on new infectious diseases for 119 emergency medical technicians (EMT). This data collection period was a total of 39 days from August 10 to September 18, 2022, and a total of 105 copies were collected. The analysis of this study used the SPSS 25.0 program. As a result of the study, among the 119 paramedics, the gender of the EMT was 54 men (51.4%) and 51 women (48.6%), with more men than women, with 47 people in their 20s (44.8%) and those in their 30s or older. There were 58 people (55.2%), most of whom were in their 30s or older. The highest total work experience was 3 to 5 years (37 people (35.2%)). In the pandemic situation, an attempt was made to check the education status of 119 paramedics on COVID-19 and the need for education on new infectious diseases. As a result of the study, the status of education on COVID-19 was insufficient. The demand for education on new infectious diseases was found to be high. Among 119 emergency responders who are frequently exposed to new infectious diseases, theoretical and practical training in personal protective equipment, stress, including theoretical training, is needed. A theoretical and practical education program on new infectious diseases and personal protective equipment should be developed as a subject for college students before becoming EMT.
Radiotherapy is commonly used in treating many kinds of cancers which cannot be cured by other therapeutic strategies. However, radiotherapy also induces the damages on the normal tissues. Radiation-induced fibrosis is frequently observed in the patients undergoing radiotherapy, and becomes a major obstacle in the treatment of intrahepatic cancer. Hedgehog (Hh) that is an essential in the liver formation during embryogenesis is not detected in the healthy liver, but activated and modulates the repair process in damaged livers in adult. The expression of Hh increases with the degree of liver damage, regulating the proliferation of hepatic progenitors and hepatic stellate cells (HSC). In addition, Hh induces epithelial-to-mesencymal transition (EMT) and activation of myofibroblasts. In the irradiated livers, up-regulated expression of Hh signaling was associated with proliferation of progenitors, EMT induction, and increased fibrosis. Female-specific expression of Hh leaded to the expansion of progenitors and the accumulation of collagen in the irradiated livers of female mice, indicating that gender disparity in Hh expression may be related with radiation-susceptibility in female. Hence, Hh signaling becomes a novel object of studies for fibrogenesis induced by radiation. However, the absence of the established experimental animal models showing the similar physiopathology with human liver diseases and fibrosis-favorable microenvironment hamper the studies for the radiation-induced fibrosis, providing a few descriptive results. Therefore, further research on the association of Hh with radiation-induced fibrosis can identify the cell and tissue-specific effects of Hh and provides the basic knowledge for underlying mechanisms, contributing to developing therapies for preventing the radiation-induced fibrosis.
Tissue fibrosis is an eventual pathologic change of numerous chronic illnesses, which is characterized by resident fibroblasts differentiation into myofibroblasts during inflammation, coupled with excessive extracellular matrix deposition in tissues, ultimately leading to failure of normal organ function. Now, there are many mechanistic insights into the pathogenesis of tissue fibrosis, which facilitate the discovery of effective antifibrotic drugs. Moreover, many chronic diseases remain a significant clinical unmet need. For the past five years, many research works have undoubtedly addressed the functional dependency of ginsenosides in different types of fibrosis and the successful remission in various animal models treated with ginsenosides. Caveolin-1, interleukin, thrombospondin-1 (TSP-1), liver X receptors (LXRs), Nrf2, microRNA-27b, PPARδ-STAT3, liver kinase B1 (LKB1)-AMPK, and TGF-β1/Smads are potential therapy targeting using ginsenosides. Ginsenosides can play a targeting role and suppress chronic inflammatory response, collagen deposition, and epitheliale-mesenchymal transition (EMT), as well as myofibroblast activation to attenuate fibrosis. In this report, our aim was to focus on the therapeutic prospects of ginsenosides in fibrosis-related human diseases making use of results acquired from various animal models. These findings should provide important therapeutic clues and strategies for the exploration of new drugs for fibrosis treatment.
