Subgenus Bothynoptera Schaum, 1863 of the genus Parena is mainly found in Oriental region. Despite this widespread distribution, species of the subgenus Bothynoptera are poorly known in Korea. While a total of 14 species have been recorded worldwide, only 3 species have been recorded in Korea. In this study, as a revisional work of Korean known species, a pictorial key and photographs of habitus and male genitalia for each species are provided, with a newly recorded species in Korea.

Kori unit 1, Korea’s first light-water nuclear power plant, was permanently shut down in June 2017. The operator, Korea Hydro & Nuclear Power Co. (KHNP), submitted a final dismantling plan for Kori unit 1 to the Nuclear Safety and Security Commission (NSSC) in May 2021. Pursuant to this procedure, the NSSC is preparing regulations for the decommissioning stage of large nuclear facilities for the first time in the Republic of Korea. The Korea Institute of Nuclear Non-proliferation and Control (KINAC) is also considering applying regulations on safeguards. Moreover, the International Atomic Energy Agency (IAEA) developed the “International Safeguards Guidelines for Nuclear Facilities under Decommissioning” in 2021. The guidelines describe the detailed application of safeguards measures to be considered when decommissioning nuclear facilities, dismantling essential equipment, and providing relevant information to the IAEA, as well as the scope of IAEA inspections. In addition, Dr. R. Bari of the Brookhaven National Laboratory (BNL) proposed the Facility Safeguardability Assessment (FSA), a methodology that reflects facility characteristics from the design stage to ensure that designers, national regulators, and the IAEA communicate smoothly regarding safeguards measures. The FSA process derives expected problems with safeguards measures considering new nuclear facilities by analyzing the gap of safeguards measures applied to existing similar nuclear facilities. This study uses the existing FSA methodology to predict problems related to safeguards measures when decommissioning nuclear facilities and to analyze deviations from safeguards measure requirements according to IAEA guidelines. To this end, the reference facility is set as an operating pressurized light water reactor; the issues with the safeguards measures are summarized using the FSA Process; and a draft safeguards concept for nuclear facilities under decommissioning is designed. Furthermore, validity is confirmed through a simple analysis of the diversion path, and implications and lessons are derived. Through this, it is possible to anticipate new safeguards measures to be applied when decommissioning nuclear facilities in the Republic of Korea and review problems and considerations in advance.

평균연령의 증가에 따른 인구고령화는 현대사회의 공통적 당면과제이며, 이에 따른 퇴행성 근감소증의 발생 및 증가는 이에 대한 새로운 해결책을 요구한다. 근감소증은 단백질의 불균형 및 운동부족, 염증 증가 등 다양한 요소에 의해 발생하므로, 과학적 원인분석을 통한 다각도적 접근이 필요하다. 이는 식품산업의 새로운 블루오션을 창조 할 수 있으나, 현재 국내의 근감소증 개선 식품성분에 관한 연구는 태동 단계라고 할 수 있다. 제품 개발 현황의 경우 단백질을 이용한 제품이 대다수인 반면, 미국의 경우 단백질 유래 원료뿐만 아니라 현미, 갈조류, 사과껍질 등 식물 유래 원료를 이용하여 다양한 제품을 출시하고 있다. 또한, 근감소증 개선 효과가 있는 원료에 대한 특허 출원 은 증가하는 추세지만, 지표성분에 대한 연구는 아직 미비하다. 국내와 비교했을 때 미국을 비롯한 국외 학계 및 산업계는 비교적 많은 연구와 개발을 이루고 있다. 하지만 제품의 소재가 주로 대두단백 및 유청단백 등에만 국한되어 있으며, 운동보조제 위주의 접근으로 인해 제형의 한계가 존재하는 상황이다. 따라서, 근감소증을 개선할 수 있는 다양한 과학적 기작 연구와 함께 소재개발을 통하여 식품 산업의 새로운 시장을 열어갈 선구적 연구가 필요하다.
