At the Korea Institute of Radiological and Medical Sciences, physical human phantoms were developed to evaluate various radiation protection quantities, based on the mesh-type reference computational phantoms of the International Commission on Radiological Protection. The physical human phantoms were fabricated such that a radiophotoluminescent glass dosimeter (RPLGD) with a Tin filter, namely GD-352M, could be inserted into them. A Tin filter is used to eliminate the overestimated signals in low-energy photons below 100 keV. The measurement uncertainty of the RPLGD reader system based on GD-352M should be analyzed for obtaining reliable protection quantities before using it for practical applications. Generally, the measurement uncertainty of RPLGD systems without Tin filters is analyzed for quality assurance of radiotherapy units using a high-energy photon beam. However, in this study, the measurement uncertainty of GD-352M was analyzed for evaluating the protection quantities. The measurement uncertainty factors in the RPLGD include the reference irradiation, regression curve, reproducibility, uniformity, energy dependence, and angular dependence, as described by the International Organization for Standardization (ISO). These factors were calculated using the Guide to the Expression of Uncertainty in Measurement method, applying ISO/ASTM standards 51261(2013), 51707(2015), and SS-ISO 22127(2019). The measurement uncertainties of the RPLGD reader system with a coverage factor of k = 2 were calculated to be 9.26% from 0.005 to 1 Gy and 8.16% from 1 to 10 Gy. A blind test was conducted to validate the RPLGD reader system, which demonstrated that the readout doses included blind doses of 0.1, 1, 2, and 5 Gy. Overall, the E_n values were considered satisfactory.

In this paper, we designed the RFID(Radio Frequency Identification) Emergency Medical Information System(REMIS). This REMIS offers the emergency patient's medical information using RFID and HL7(Health Level 7) to an emergency medical technician. In emergency situation as like coma, if the communication, from the patient's current location to the hospital, is possible, REMIS offer the medical information of the patient through REMIS server to an emergency medical technician. In the state of communication blocked, REMIS can offer the patient identification and the emergency information through RFID tag, which the patient wear, to an emergency medical technician. When this system was designed, the protection of the patient's medical information and their privacy was considered, and the HL7 was used to be compatible with another medical systems. Therefore, in this paper, REMIS was designed that it is always possible to offer the emergency patient's information to an emergency medical technician regardless of any communication status and to improve the emergency rescue process, effectively.

This thesis has defined the legal status of 119 rescue who plays a major role in the Korean prehospital emergency medical system and reviewed the various issues that may occur depending on work related legal liabilities. As a result, the purpose of this study was to represent the countermeasures for legal protection of 119 rescue required for the quality improvement of prehospital emergency medical system and as well as the countermeasures for risk management prepared for its related lawsuits. The legal liabilities of 119 rescue officers can be divided largely into public law liabilities and civil and criminal liabilities. In order to decrease the incidences of legal problems and provide the legal protection to rescue officers, the liability of supervising physician should be emphasized when the emergency medical practice is performed by a rescue officer under their supervision by consolidating medical control and the rescue officer should have legal liability on his emergency medical practice. itself Also, the emergency medical service guideline for 119 rescue officers should be prepared and their works should be performed according to such a guideline and procedures. In addition, the accurate legal documentation on emergency medical system from on-site to ER and related mobilization should be framed and preserved. Moreover, it is required to enact a new law such as the Good Samaritan Act or the Rescue Officers Protection Act.

Background: In case of radiation emergencies, internal exposure monitoring for the members of public will be required to confirm internal contamination of each individual. In-vivo monitoring technique using portable gamma spectrometer can be easily applied for internal exposure monitoring in the vicinity of the on-site area. Materials and Methods: In this study, minimum detectable doses (MDDs) for $^{134}Cs$, $^{137}Cs$, and $^{131}I$ were calculated adjusting minimum detectable activities (MDAs) from 50 to 1,000 Bq to find out the optimal in-vivo counting condition. DCAL software was used to derive retention fraction of Cs and I isotopes in the whole body and thyroid, respectively. A minimum detect-able level was determined to set committed effective dose of 0.1 mSv for emergency response. Results and Discussion: We found that MDDs at each MDA increased along with the elapsed time. 1,000 Bq for $^{134}Cs$ and $^{137}Cs$, and 100 Bq for $^{131}I$ were suggested as optimal MDAs to provide in-vivo monitoring service in case of radiation emergencies. Conclusion: In-vivo monitoring program for emergency response should be designed to achieve the optimal MDA suggested from the present work. We expect that a reduction of counting time compared with routine monitoring program can achieve the high throughput system in case of radiation emergencies.

The purpose of this study is to explore the improvement method of the emergency safety system as a social protection scheme for the elderly living alone with severe disabilities. The study was conducted by randomly choosing three regions in the metropolitan area (Jongno-gu, Seoul), the small-medium city (Yongin-si, Gyeonggi-do) and the rural area (Geochang-gun, Gyeongsangnam-do) among 17 cities and counties nationwide. The study method is based on the interview form of the structured questionnaires with city officials, county officials, and center operators. According to the results of the interview analysis, it was recognized that there was a need for an emergency safety system for the elderly living alone with severe disabilities. In spite of this necessity, there were problems about publicity for the discovery of victims of the blind spot in welfare, about inconvenience due to frequent malfunctions of the emergency equipment, about insufficient awareness of the security of the emergency officials and about supply and demand of manpower for 24-hour monitoring service. In order to improve the effective operation of the emergency safety system, it was the most urgent issue to formulate the legislation for responding to the crisis management of the vulnerable. A suggestion of this study is to build a safety system in which one-stop service is provided for the realization of compact welfare through the establishment of a MOU for linkage with community organizations, the full inspection of emergency equipment to solve safety equipment malfunction problems and the manpower supplement for 24-hour monitoring.

Even now, 119 rescue services have dissatisfactory aspects in operation, system and equipments as discussed above, It is the most urgent subject to systemize rescue services so that they can be suitable for our status, for we will make 21C welfare state come true before long. So, this author suggest that the followings have to be raised to activate 119 rescue service. 1) Bring up experts and offer high-quality rescue service 2) Prepare more up-to-date equipments 3) Operate transfer joint organizations 4) Promote the ability to meet with a press at the time of rescue service activities 5) Adjust regulations related to rescue services 6) Make up for a countermeasure to traffic accidents of ambulances 7) Adjust regulations making it mandatory to establish heliport at the target on hospitals more than a defined scale 8) Install more rescue service teams 9) Educate and train officials belonging to briefing rooms, where the officials with long experiences are arranged 10) Minimize the time for rescue team to reach fields 11) Establish legal protection system for rescue the team Nowadays, our country operates the department of fire fighting and rescue services without great difficulty, even though the circumstances are bad - insufficient members and the inferior circumstances. All of the fire fighting officials are given heavy duties in bad circumstances, and so are the team of rescue service. The rescue service team, taking charge of some emergency medical system, do a fire fighting inspection as a non-duty service, though they are scanty of sleep due to prevention and protection services of the fire fighting service team. But, they can not engage in rescue services completely and have to deal with miscellaneous duties. So they can not offer professional emergency medical services. But now, almost every fire fighting organization, belonging to National Emergency Management Agency, are separating rescue services, which shows a lot of good results. People recognize rescue services to get better and better gradually and the demands for this rescue services increase. So, this is the best time when rescue service teams should offer qualitative services rather than quantitative services. The people will recognize this rescue service team to be an organization sacrificing and serving for them. However well institutes and operation systems should be established, the rescue service team can not come true their aim without strong wills that they will serve and sacrifice themselves for people from their hearts. In addition, it is essential for the officials in charge of policies about emergency medical services to have a concernment on and practice the policy without failure.

Background: To find out the leak characteristic of research reactor 'HANARO' building in a typhoon condition Materials and Methods: MELCOR code which normally is used to simulate severe accident behavior in a nuclear power plant was used to simulate the leak rate of air and fission products from reactor hall after the shutdown of the ventilation system of HANARO reactor building. For the simulation, HANARO building was designed by MELCOR code and typhoon condition passed through Daejeon in 2012 was applied. Results and Discussion: It was found that the leak rate is $0.1%{\cdot}day^{-1}$ of air, $0.004%{\cdot}day^{-1}$ of noble gas and $3.7{\times}10^{-5}%{\cdot}day^{-1}$ of aerosol during typhoon passing. The air leak rate of $0.1%{\cdot}day^{-1}$ can be converted into $1.36m^3{\cdot}hr^{-1}$, but the design leak rate in HANARO safety analysis report was considered as $600m^3{\cdot}hr^{-1}$ under the condition of $20m{\cdot}sec^{-1}$ wind speed outside of the building by typhoon. Conclusion: Most of fission products during the maximum hypothesis accident at HANARO reactor will be contained in the reactor hall, so the direct radiation by remained fission products in the reactor hall will be the most important factor in designing emergency preparedness for HANARO reactor.
