The objective of this study is to investigate the safety awareness and effectiveness of the education and training for employees engaged in radiological emergency organization of the Korea Atomic Energy Research Institute (KAERI). In 2022, the questionnaire for the education satisfaction survey was revised to regulary evaluate the effect of edcation on perceptions of importance on emergency preparedness for nuclear research facilities. In line with, a standard questionnaire was created which covers 3 factors and 9 attributes, and the evaluation indicatior is based on a 5-point Likert scale. In 2023, the education on radiological emergency preparedness was conducted for 235 emergency staff. From May 24 to July 13, 2023, data was collected from a total of 235 emergency response personnels, including 28 new staffs and 207 maintenance staffs. Aa a result of response analysis, it was identified that education for radiological emergency response had a significant correlation with the promoting safety culture. It was found that senior emergency personnel with more years of experience are highly interested in radioactive disaster prevention and actively participate in and training. On the other hand, it was presented that new and less experienced groups tend to have a relatively high scored of the risk perception of nuclear research facilitites. Therefore, it is necessary to improve the practical curriculum in order to increase the participation of junior disaster prevention personnel in education and training, ensuring that they correctly recognize the risk of research facilities. This results are expected to be used to improve the quality of education and drills for radiological emergency response at KAERI.

Employees of nuclear licensees have to take the education for radiological emergency preparedness, as prescribed by presidential Decree. The Korea Atomic Energy Research Institute (KAERI), as an educational institution designated by the Nuclear Safety and Security Commission (NSSC), has been conducting field-oriented workplace education. This aims to enhance understanding of radiological emergencies that may occur in nuclear facilities and to strengthen response capabilities to prevent and deal with accidents in the event of radiation emergencies or radioactive disasters. To accomplish these educational goals, a paradigm shift from the previous theory-oriented curriculum to a participatory curriculum with high field applicability is needed to strengthen the ability to respond to nuclear or radiological emergencies. In addition, a feedback system is required to manage the quality of education and improve the curriculum. In this regard, KAERI sought ways to revitalize the education to strengthen the emergency response competencies. Based on the concept of the Systematic Approach to Training (SAT) methodology, which is recommended by the International Atomic Energy Agency (IAEA) for the development and implementation of education and training for NPP personnel, an educational model and its feedback system were developed. Then, a field-oriented participatory curriculum operation and satisfaction survey were conducted to evaluate the educational effectiveness. Lastly, the survey results were discussed in a critique session to point out weaknesses and indicate areas for improvement, and then were used as data for educational quality assurance. This paper introduces the composition and effectiveness of KAERI’s SAT-based education model based on its recent three years of experience.

Once a radioactive material is released from the nuclear power plant (NPP) by accident, it is necessary to understand the behavior of radioactive plume to protect residents adequately. For this, it is essential to measure the radiation dose rate around NPPs at important locations. Our previous study developed a movable radiation detector that can be installed quickly in an accident to measure gamma dose rate in areas where environmental radiation monitoring system is not installed. The data measured by the detector are transmitted to the server in real-time through LoRA wireless communications. There are two methods to use LoRA communications; one is self-network, and the other is the network provided by the mobile carrier. A signal receiver, called a gateway, should be equipped near the installation location of radiation detectors to use a self-network without using the mobile carrier’s system. In other words, the movable radiation detectors we made can function if there should be any gateway near them. The distance capable of communication between gateway and detector is about 8 km in an open area without significant obstacles. Korea has many significant obstacles, such as mountains around most NPPs. Thus, the gateways could be installed in the proper position before the accident to operate the movable radiation detectors without problems. If the gateway is located at a high position like a mountain top, it could cover a wide area. In this study, the elevation database in the area around the NPPs was collected and analyzed to determine where gateways should be installed. The analysis range is limited in the urgent protective action planning zone. The optimization was also performed to minimize the number of gateways.

The 4th industrial revolution is in its progressive form, and its effects are already being revealed throughout society. It has led to a variety of new technologies including artificial intelligence (AI), big data, Internet of Things (IoT), robotics, cyber-physical systems, biotechnology, 3D printers, drones, and Uber. The winds of this revolution are expected to bring many changes to the manufacturing industry. The low-growth global economy and a decline in productivity are prompting a 4th industrial revolution centered on Europe’s Germany, as it needed new growth engines. In Korea, manufacturing industries focused on labor and capital were the center of the industry. The goal was to pursue the first and second industrial revolution led by the developed countries, and to achieve what is called the “Miracle of the Han River”, “The Four Dragons for Asia”, and “The East Asian Miracle”. However, unlike the past, the 4th industrial revolution is not expected to bring about theoretical but substantial changes. The preparations and research into the 4th industrial revolution may seem to be ahead of the major countries, but unfortunately it is far behind the major ones. The United States, China, Germany and Japan are in the process of reorganizing the society, culture and economy in relation to the 4th industrial revolution. Korea`s economy, however, is showing a decline in the growth rate, with the exception of technical hardware and equipment and telecommunications. The 4th industrial revolution is an industry that requires highly specialized knowledge, information, and technology, and if it fails to respond to rapidly evolving technological changes and trends, it is bound to be relegated to the government's position. For small and medium sized manufacturers in particular, the longer the preparation is delayed due to poor environment, structural backwardness, lack of core competencies, and lack of innovation, the more likely they will adjust to social and technological changes caused by the 4th industrial revolution. Accordingly, it is necessary to enhance the importance of preparation for the 4th Industrial Revolution and to take strategic approaches to enhance the sophistication of technologies and the autonomy of small and medium sized manufacturing companies. In this study, we intend to study the manufacturing-ready effects of manufacturing industries based on the level of perception of the company’s 4th industrial revolution. For this purpose, 122 small and medium manufacturing companies were surveyed on the 4th industrial revolution. The survey was conducted for about four months from December 1, 2017 to March 31, 2018. In the case of small and medium sized manufacturing companies, a hypothesis was established on how the perception and preparation of the industrial revolution affects the direct preparation of the 4th industrial revolution. Three assumptions were presented depending on the level of perception of the 4th industrial revolution and the data were drawn from the questionnaire. When comparing the data to the hypothesis, small and medium manufacturing companies should be able to determine the level of interest they have in the 4th Industrial Revolution, and if they are not prepared to do so, they should be able to invest in a certain extent.

Owing to climate change and global warming, foodborne infectious diseases are becoming inevitable problems in many countries, and this is also the case in Korea. One of the causal factor of foodborne disease outbreak in the food service business(i.e. restaurant or mass feeding facilities) is inappropriate management of infected food handlers. The need for strengthening of the indications for managing infected food handlers is emphasized continuously. However, precise legal interpretations or analyzation should be done based on microbiological fundamentals before strengthening the guidelines. Therefore, this study analyzes the legal policies of Korea associated with infection control of food handlers and proposes shortcomings or supplementations to existing legal policies.

해상 유통되는 유해액체물질(NLS)의 유출사고대비 물질군 선정을 위해 596종의 NLS를 대상으로 위해성 DB를 구축하고 우선순위 선정시스템을 통해 전체 우선순위를 선정하였다. 우선순위 목록을 바탕으로 2014-2015년 해상유통물질 158종을 추출한 뒤 물질군 구분 기준을 적용하여 0~3순위의 4개 물질군을 제시하였다. 국가차원의 NLS 유출사고대비를 위해서는 물동량 및 유해성이 높은 0~1순위 물질군의 집중관리와 함께 2~3순위 물질군의 정보 구축작업이 지속되어야 한다. 항만별로는 NLS 유통 유형이 다르므로 각 항만의 물질별 유통특성을 파악한 뒤 0~1순위 물질군 위주로 관리하는 것이 효율적일 것으로 판단된다. 또한, 동해남부권역(울산, 부산), 남해중부권역(광양, 여수), 서해중부권역(평택, 대산, 인천)을 NLS 사고대비를 위한 특별관리구역으로 지정하여 해상유통되는 NLS 의 감시·감독을 강화하고 방제 장비, 자재 및 약제를 집중 배치해야 할 것으로 판단된다. 향후, 위해성 DB의 구축과정에서 나타난 위해성 정보 부재 물질들의(만성독성) 지속적인 생산 및 보완이 필요하며, 특히 수생태 독성의 경우 해양생물종을 대상으로 한 자료 생산 및 확보가 지속되어야 할 것이다. 또한, 해상 HNS 사고 관리를 위해서는 HNS 해상유통에 대한 정보를 확인할 수 있는 시스템이 조속히 구축되어야 한다.

Climate change by global warming is predicted to affect on public health including increasing incidence of vector borne diseases. Vector borne diseases are transmitted by arthropod vectors, such as mosquitoes, chigger mites and ticks, and are highly sensitive to climate changes. The surveillance and R&D of infectious disease vectors are becoming important for climate change preparedness in Korea. So far, 10 regional vector surveillance centers (Incheon, Gyeonggi, Gangwon, Chungbuk, Chungnam, Jeonbuk, Jeonnam, Gyeongbuk, Gyeongnam, and Jeju) have been established to monitor vectors and their pathogens against endemic diseases (japanese encephalitis, malaria, scrub typhus and SFTS) and imported diseases (dengue fever, west nile fever and yellow fever). The information on geographical distribution as well as real-time monitoring of vectors and their pathogens will be presented by this surveillance system, ‘VectorNet’. The R&D plan on vectors and their pathogens is now discussing in government-wide R&D committee on infectious diseases. The R&D areas will be included: 1) establishment of nationwide monitoring system, 2) study on biological and molecular characteristics, 3) development of vector identification and pathogen diagnosis methods, 4) development of vector control techniques, 5) management and conservation of vector resources.
