  • 다중입력조건에 따른 단일 출력퍼지시스템인 인구밀도와 도로조건에 따른 소개속도의 모델링시스템에서는 인구밀도와 도로조건의 퍼지멤버쉽에 대한 소개속도의 상승작용을 확인할 수 있었다. 그러나 도로조건을 평가하는 방법을 포장과 비포장으로만 구분함으로 인해 발생하는 퍼지추론과정에서 비탄력성은 향후 도로조건에 대한 세밀한 조사를 통하여 퍼지멤버쉽함수의 형태를 재고해야 할 것으로 판단된다. 실제 원자력시설에서 발생할 수 있는 사고의 경우 방사능에 노출될 수 있는 일반대중은 방사능에 대한 깊은 지식을 가지지 못하는 경우가 대부분이다. 따라서 차폐효과 혹은 소개속도를 정량적으로 파악하기 힘든 경우가 많다. 따라서, 이러한 퍼지시스템은 방사선 비상대응 시스템을 개발하는 의사결정자나 비상시 방사능에 노출되는 사람들의 대응 방식을 모델링하는데 유용할 것으로 판단된다.

  • The accident in the Fukushima nuclear plant caused by the Great East Japan Earthquake on March 11, 2011 is raising voices concerning over radioactive contamination losses. In particular, radioactive contamination losses threaten the safe navigation of vessels, and may impair seafarers' safety and impede the healthy growth of world economy through marine transportation. In case vessels or cargos suffer radioactive contamination losses, it will take a high cost to remove the radioactive contaminants, and in worse cases the contaminated vessels or cargos may have to be abandoned. Furthermore, if seamen are exposed to radioactivity, their treatment can be raised as a crucial issue. Nevertheless, it has not been reviewed clearly by what method and on what ground such losses should be covered in case radioactive contamination losses take place. Thus, this study purposed to review coverage for radioactive contamination losses in marine insurance as an ex post preparation for damages caused by radioactive contamination.

Estimation of willingness to pay of workers who are engaged in nuclear power R&D projects to avoid exposure to radioactive matters by using a choice experiment (선택실험설문에 의한 방사능 피폭 가능성에 대한 원자력 기술개발 종사자의 지불용의액 추정)

  • Since catastrophe from explosion of Hukushima nuclear power plant, concerns over possibility of exposure to radioactive matter has been disseminating all over the world and frequent accidents of domestic nuclear power plants also has been amplifying throughout the nation. In the past, major focus was made on compensation for local residents who live nearby nuclear power plants, but focal point of this study is on wage premium of workers who are employed in R&D of nuclear power plants. It is difficult to derive socially desirable result if private sectors are responsible for compensation on workers who suffer from physical damages due to the exposure to radioactive matter. Because victims should verify the damages that occur in the working places. This study conducted a survey on which job would prefer the respondents who are engaged with the nuclear R&D projects as exposure levels to radioactive matter, security of job, location of firms, and work intensity differ. As a result, exposure to radioactive matter was the most important attribute in choosing alternative jobs followed by job security, work intensity and job location. Annual willingness to pay for reduction of exposure to radioactive matter was estimated as 7730~7770 thousand KRW depending on different econometric models. Therefore, Korean government should prepare institutional foundation in order that appropriate compensation should be made on workers who are engaged in R&D projects on nuclear power plants if they have damages from the exposure to radioactive matter.

  • In 2011, the Fukushima nuclear power plant accident in Japan resulted in more than 1.3 million tons of radioactive contaminated water, and the Japanese government has been releasing large amounts of contaminated water into the ocean since 2023. This accident has raised concerns about marine pollution and seafood consumption, as well as the effects on highly radiosensitive children and fetuses. Radiation protection materials are being researched to better prepare for various radiation accidents, including marine radioactive contamination incidents. Natural radioprotectors have fewer side effects and are more easily commercialized than chemical radioprotectors. This study aimed to confirm the function of a mixture of folic acid and α-tocopherol, natural antioxidants, in protecting living organisms from radiation. In the experiment, Spraque-Dawley rats (SD rats) were used to induce pregnancy to target fetuses with high radiation sensitivity, and the second generation's skeletal system, blood analysis, body weight, spleen, brain, and small intestine were examined after birth. After administering a mixture of folic acid and α-tocopherol, the irradiated group showed significant recovery (p<0.05) in blood analysis, small intestinal villus length, and cerebral cortex thickness measurements compared to the comparison group (irradiated group), suggesting that the mixture of folic acid and α-tocopherol is effective for in vivo radioprotection in a radioactive contaminated environment.
