        Spent nuclear fuel temporary storage in South Korea is approximately 70% of total storage capacity as of the 4th quarter of 2022 amount is stored. In addition, according to the analysis of the Korean Radioactive Waste Society, saturation of nuclear power plant temporary storage is expected sequentially from 2031, and accordingly, the need for high-level radioactive waste disposal facilities has emerged. Globally, after the conclusion of the EU Taxonomy, for nuclear energy in order to become an ecofriendly energy, it is necessary to have a high-level radioactive waste disposal site and submit a detailed operation plan for high-level radioactive waste disposal site by 2050. Finland and Sweden have already received permission for the construction of high-level radioactive waste disposal facilities, and other countries, such as Switzerland, Japan, the United States, and Canada, are in the process of licensing disposal facilities. In order to establish a repository for high-level radioactive waste, the performance and safety analysis of the repository must be conducted in compliance with regulatory requirements. For safety analysis, it needs a collection of arguments and evidence. and IAEA defined it as ‘Safety case’. The Systematic method, which derives scenarios by systematizing and combining possible phenomena around the repository, is widely used for developing Safety case. Systematic methods make use of the concept of Features, Events and Processes (FEP). FEP identifies features that affect repository performance, events that can affect a short period of time, and processes that can have an impact over a long period of time. Since it is a characteristic of the Systematic method to compose a scenario by combining these FEP, the Systematic method is the basic premise for the development of FEP. Completeness is important for FEP, and comprehensiveness is important for scenarios. However, combining all the FEP into one scenario is time-consuming and difficult to ascertain the comprehensiveness of the scenario. Therefore, an Integrated FEP list is being developed to facilitate tracking between FEP and scenarios by integrating similar FEP. In this study, during the integrated FEP development process, a method for utilizing experts that can be used for difficult parts of quantitative evaluation and a quantitative evaluation process through the method were presented.

        The distribution of mosquitoes collected in Cheongju area in 2016 and 2017 were compared. The collection sites wereestablished from residential area, migratory bird sanctuary, and cattle feedlot using BL trap and BG trap. Culex pipienswere the most collected in residential area, and Aedes vexans were the most collected in migratory bird sanctuary andcattle feedlot in both years. BG trap was more collected than BL trap in residential area and migratory bird sanctuary.However, cattle feedlot was more collected in BL trap. A variety of mosquito species were collected from BG trap thanBL trap. However, the number of Anopheles sinensis collected in cattle feedlot showed significant differences betweenBL trap and BG trap. Based on the results of this study, it is considered that effective monitoring of mosquitoes mightbe done by using appropriate trap type according to the region

        국내수집 검정콩 유전자원의 안토시아닌 함량을 평가 및 선발함으로써 안토시아닌 고함유 신품종 육종 모재로 활용하고자 본 연구를 수행하였다. 공시재료는 농촌진흥청 생명공학연구소 유전자원과로부터 분양받은 274 수집계통(2002년 38계통, 2006년 236계통)과 경기도농업기술원 작물연구과에서 자체 수집 보관하던 18 수집계통이었으며, 2006년도에 경기도농업기술원 작물연구과 전작포장에서 재배하고 수확한 후 성분을 분석하였다. 검정콩 종피에 함유된 안토시아닌의 주성분은 cyanidin-3-glucoside(C3G), dephinidin-3-glucoside(D3G), petionidin-3-glucoside(Pt3G) 등이었으며 분석결과는 다음과 같았다. 1. 수집지역간의 총안토시아닌 함량은 충남 수집종이 평균 13.75±4.709mg/g 으로 가장 높았고, 총안토시아닌 함량별 유전자원 분포는 9.1~12.0mg/g 범위가 84종으로 가장 많았으며, 6.1~9.0mg/g 65종, 12.1~15.0mg/g 41종, 15.1~18.0mg 39종 순이었다. 2. C3G는 3.1~6.0mg/g 범위가 116종으로 가장 많았고, D3G와 Pt3G는 0~3.0mg/g 에서 각각 288종, 268종이었다. 이중 D3G와 Pt3G가 결핍된 유전자원은 각각 4종통, 24종이었다. 3. 착색기~성숙기 소요일수에 따른 총안토시아닌 함량은 착색소요일수 16일 이하에서는 7.82±4.304mg/g 이하였으나, 35일 이상에서 13.09±4.190mg/g 으로 뚜렷하게 증가하였다. 4. 성숙소요일수에 따른 안토시아닌 함량은 소요일수가 길어질수록 높아져 86일 이상에서는 15.98±3.935mg/g 이었다. 5. 수확시기에 따른 총안토시안닌 함량은 9월 하순부터 높아져 10월21일 이후 수확된 유전자원에서 15.75±3.402mg/g 으로 가장 높았는데, 개별 안토시아닌에서도 C3G와 D3G는 같은 경향이었다.
