Purpose: Emergency medical technicians (EMTs) have so far been trained as professionals under the same conditions, with no change in the 1995 Act. We aimed to find ways for them to secure expertise in accordance with social needs by strengthening the quality of the EMT education. Methods: This is a descriptive study comparing the operation status of the national emergency medical examination conducted by the Korea Health Personnel Licensing Examination Institute, and the national examinations of EMT paramedic and EMT basic. The scope of the national examinations for EMT was compared by subject and area. Results: The national written exam for EMT paramedic consists of five areas. EMT basic does not include basic medicine in three related subjects, 11 areas, and 18 detail areas. Paramedic care does not include advanced pediatric life support. In addition, nine areas and 20 detail areas are not included. Conclusion: The study suggests the need for institutional supplementation so that those who have completed EMT basic and the subjects prescribed by the ordinance of the Ministry of Health and Welfare at universities, etc., in the Higher Education Act can take the EMT paramedic national exam.

Purpose: The I-gel device is Korea's most frequently used airway management method during pre-hospital cardiopulmonary resuscitation (CPR). This study aimed to compare changes in ventilation volume according to the fixation method with a simulated manikin. Methods: We placed I-gel into an advanced life support simulator and compared tape and band fixation conditions. CPR was performed according to the 2020 Korean CPR guidelines, using a mechanical chest compression device and an adult bag. The positional shift of I-gel and the ventilation volume of the simulated manikin were measured after performing CPR for 20 minutes. Five trials were carried out in each setting. Statistical analysis was carried out with SPSS 27.0. P < .05 was considered significant. Results: Positional shift after 20 minutes of CPR was as follows: tape fixation, 7.2 ± 0.2 mm; band fixation, no change, indicating a significant difference between the two groups (p=.003). The mean ventilation volume was tape fixation, 482.63 ± 30.84 mL; band fixation, 544.96 ± 22.98 mL, showing a significant difference (p=.002). Conclusion: When using the I-gel during pre-hospital CPR, using a band-type fixing device with elasticity rather than fixing the tape provides stable and appropriate ventilation by maintaining the fixed position.

Purpose: TThe experiment was designed to compare the efficiency of ventilation between conventional BVM ventilation and a newly devised A-BVM ventilation method with Tidal volume, total ventilation rate, average Ventilation speed, and average Ventilation volume. Methods: 40 Paramedical students who agreed to participate in the study were analyzed. Values were measured using IMB PASS after 2 minutes of Brayden Pro manikin with BVM and A-BVM ventilation. The difference in general characteristics was assessed by t-test and ANOVA and the difference in ventilation methods was analyzed by IBM SPSS. Results: A significant difference was found between the two ventilation methods in terms of tidal volume (t=-11.203, p<.001), ventilation time (t=-3.834, p<.001), and optimum ventilation probability (t=10.770, p<.001). A-BVM ventilation method, rather than BVM ventilation method, showed a value close to the appropriate amount recommended by Korean Advanced Life Support (500~600mL) in tidal volume, and higher in optimum ventilation probability. Conclusion: We could identify the a better mode of ventilation. Further studies on the efficacy of existing BVM ventilation methods as compared to device augmented BVM ventilation methods should be carried out to ensure that adequate ventilation is available to patients in clinical practice.

Recently, the world has been considering hydrogen energy as the primary energy transition means to achieve carbon neutrality by 2050. In order to achieve the goal of reducing greenhouse gas emissions, Korea is also promoting a clean hydrogen economy. However, it is necessary to introduce various clean hydrogen from overseas so that the projected demand can not meet the domestically produced. For this study, we conducted the policy comparison approach between countries other than the generally considered technical and economic approaches. The finding proposes the direction of bilateral cooperation for a strategy of securing overseas clean hydrogen from a geopolitical perspective. Germany was a target country for the policy comparison since it has a high proportion of manufacturing, like Korea, and is taking the lead in the renewable-based energy transition policy. According to the survey and analysis of the policy establishment status and new projects of the two countries, Germany is promoting bilateral international cooperation in the hydrogen area with about 33 countries based on 7 types of activities. In comparison, Korea is involved in bilateral cooperation with about 12 countries on relatively few activities. Among the types of bilateral cooperation, R&D cooperation with advanced countries for hydrogen technology was a common activity type. Germany preemptively promotes cooperation for demonstration and commercialization, considering geopolitical means and strengthening manpower training and assistance on policy and regulation to preoccupy the market for the future. Therefore, it is necessary to consider establishing a network of an entire life cycle of supply and demand network that links the future market with securing clean hydrogen considering the geopolitical distribution. To this end, Korea also needs to expand bilateral cooperation countries by activity type, and it seems necessary to seek various geopolitical-based bilateral cooperation and support measures for developing countries to diversify the supply sources of hydrogen.

Article 10 of the Constitution All citizens have dignity and values as humans and have the right to pursue happiness. There is a need for support measures such as a means to realize the respect of dignity and values as humans, and how to efficiently maintain policies on welfare for the elderly classified as the socially disadvantaged. It was considered necessary to develop an elderly-friendly city for economic, physical, and social life. Dasan Jeong Yak-yong's respect for adults was to practice the ideology of Confucianism, so this was the most important thing in the past Joseon Dynasty. In particular, it was considered important to think of adults first in practicing filial piety.This study focuses on the long-term care insurance system for the elderly, one of the welfare policy measures for the elderly. The significance of implementing the long-term care insurance system for the elderly is to benefit not only the elderly, but also all generations, including the middle-aged and children who were in charge of long-term care. To this end, the government should properly manage the factors of the social insurance financial crisis caused by the low birth rate and aging population.In addition, concerns about health insurance are high, so it is necessary to secure an appropriate level of government budget for health insurance financial management and minimize unnecessary non-benefit. In addition, it is necessary to induce appropriate medical use through connection with construction medical insurance.

The attempt to use a 3D model each field such as design, structure, construction, facilities, and estimation in the construction project has recently increased more and more while BIM (Building Information Modeling) that manages the process of generating and managing building data has risen during life cycle of a construction project. While the 2D Drawing based work of each field is achieved in the already existing construction project, the BIM based construction project aims at accomplishing 3D model based work of each field efficiently. Accordingly, the solution that fits 3D model based work of each field and supports plans in order to efficiently accomplish the relevant work is demanded. The estimation, one of the fields of the construction project, has applied BIM to calculate quantity and cost of the building materials used to construction works after taking off building quantity information from the 3D model by a item for a Quantity Take-off grouping the materials relevant to a 3D object. A 3D based estimation program has been commonly used in abroad advanced countries using BIM. The program can only calculate quantity related to one 3D object. In other words, it doesn't support the take-off process considering quantity of a contiguous object. In case of temporary materials used in the frame construction, there are instances where quantity is different by the contiguous object. For example, the formwork of the temporary materials quantity is changed by dimensions of the contiguous object because formwork of temporary materials goes through the quantity take-off process that deduces quantity of the connected object when different objects are connected. A worker can compulsorily adjust quantity so as to recognize the different object connected to the contiguous object and deduces quantity, but it mainly causes the confusion of work because it must complexly consider quantity of other materials related to the object besides. Therefore, this study is to propose the solution that automates the formwork 3D modeling to efficiently accomplish the quantity take-off of formwork by preventing the confusion of the work which is caused by the quantity deduction process between the contiguous object and the connected object.
