One of the important purposes of most water resources systems is to prevent from drought damages. However, there are uncertainties in water supply plans from a reservoir due to factors such as limitation of available data, inaccuracy of surveyed data, unsuitability of analysis method, and climate change. In actual operating process, severe drought exceeding the water supply capability makes the normal water usage difficult. In Korea, however, alternative water source such as a development of new water project is very limited in case of water shortages due to drought. Especially, since there is no standard to evaluate the water supply effect considering severe drought damages, it is difficult to prepare the practical measures. In this study, water shortage events of existing multipurpose reservoirs are analyzed and the method of using low-storage emergency water supply is studied by using Water Shortage Index (WSI). The water shortage events are analyzed and the effect of water shortage decrease is evaluated using the existing inflow data of multi-purpose reservoirs. The results show that Imha, Daechung, Hapchon and Namkang reservoirs are highly vulnerable to the severe drought and required to develop additional emergency water source.

Purpose: This study collects basic data on the awareness of evacuation methods and evacuation facilities in the event of a radiological disaster of residents living in the emergency planning zone. Method: The residents of emergency planning zone were sampled using a random sampling method. A 1:1 interview was conducted using a structured questionnaire, and statistical analysis was performed using the minitab program. Result: First, the survey subjects showed a relatively low and negative awareness of the local government's work on radioactive disasters. Second, in terms of resident safety education, they had little experience in education, but they felt it was necessary and wanted education on evacuation methods, action tips, and the location of relief centers. Third, the location of the relief centers related to radioactive disasters was not well known, and there were many responses that they did not receive any guidance, and that they would be with their families when using the relief centers. Satisfaction levels were generally low with regard to the relief facilities. Fourth, the necessary priorities in preparation for radioactive disasters were education and training for radioactive disasters, facility supplementation, and supply of protective chemicals. Conclusion: The residents of emergency planning zone perceived the policies and tasks of the government or local governments relatively negatively in preparation for the occurrence of radioactive disasters, and their satisfaction was low. Regarding the matters pointed out as a priority, the government and local governments should publicize and educate the residents of accurate information and policies on radioactive disasters.

Nuclear emergency planning is to plan sheltering, evacuation and iodine prophylaxis for the residents living in the area where the emergency plan is needed, the area is confirmed based on the dose assessment using the source-term through an accident analysis and the data measured from meteorological tower. In this study, the does change before and after protective measures was assessed stochastically based on the one year meteorological data in the condition of the maximum hypothetical accident which can be considered at the research reactor 'HANARO', and the optimized protective measures were derived based on the reference levels defined as a residual dose by ICRP 2007 recommendation which can be applied in a emergency exposure situation. The optimized protective measures for the HANARO in the maximum hypothetical accident were the evacuation to radius 300 m, the sheltering from 300 m to 800 m, the iodine prophylaxis only for the emergency workers under the protective measures for non emergency workers.

In this study, the acoustic characteristics of 13 types of emergency broadcasting speakers were tested under the test set-up of UL 2043 and compared. When the sound pressure level of 1 W speakers was compared with speakers with a 15 W output, the SPL of the 15 W speakers was approximately 20 dB higher in some frequency bands. Loudness analysis showed that people can recognize emergency sound from a 15 W speaker twice as loud as the emergency sound from 1 W speakers. The analysis results on the articulation index (room) had an opposite tendency with loudness results, meaning that small speakers can generate clearer sound. Therefore, it is necessary to improve emergency broadcasting speakers to generate louder and clearer sound. Moreover, a performance evaluation standard is needed based on the reasonable and quantitative measurements and evaluations of the acoustic characteristics of the emergency-broadcasting speakers so that a sufficient and clear sound can be generated in various spaces. In addition, it is necessary to establish standards for the clarity of emergency broadcasting in various spaces.

The purpose of this study is to propose an effective operating method of a power generator used by the Emergency Power System in case of a simultaneous fire and of the limitations of the interlock system the power supply from the emergency power generator. On the Emergency Power System with Reserved Fire-fighting Power (RFP), in case of an overload, the collective control Emergency Power System signals the main circuit breaker to shut off the supply to the emergency load, leaving the supply to the firefighting load uninterrupted to the end. The sequential control Emergency Power System signals the firefighting power supply to shut off the fire stage of the emergency load and continues to monitor the power supply. If an overload happens again from increased firefighting load, the sequential control Emergency Power System sends a secondary signal to shut down the second stage of the emergency load.

There are countless possibilities lying ahead of us, and while predicting the future may be challenging, it does not render the act of forecasting meaningless. Predicting various possibilities allows us to be flexible in coping with unforeseen circumstances. This study was conducted to explore extreme events (X-events) in the population sector in South Korea. To achieve this, focus group interviews were conducted with 32 emergency planning officers in government and public services. Based on these interviews, significant research findings were derived, indicating that population issues such as population decline and aging could have substantial impacts on various fields, including the economy and national defense. With this study as a catalyst, we anticipate a more active discussion and discourse on X-events that could occur in our society.

전라남도 여수시 율촌면 신풍리의 여수공항. 90년 한국공항공사가 여수지사를 설립한 이후 95년 공항시설 확장공사에 들어간 여수공항이 지난 11월 25일 신여객청사를 개관했다. 여수공항의 확장공사는 외관의 크기만 늘어나는 것이 아니다. 내부의 전등기기, 기계실 기기 등을 고효율기기를 활용하여 '에너지 절감'의 효과도 잡아내고 있다. 새로워진 모습으로 국제화를 위해 비상할 여수공항을 찾았다.
