Background: Despite the increasing number of older adults as the population ages, there is a lack of frailty prevention guidelines for community-dwelling older adults. The Korean Frailty and Aging Cohort Study conducted systematic review on contributors to frailty and developed guidelines on the primary prevention of frailty in community-dwelling older adults. Methods: This study updated a previous systematic review of contributors to frailty by adding the most recent articles. Based on this updated systematic review, experts in geriatrics and gerontology developed guidelines for preventing frailty using the Delphi method. Results: These guidelines categorized the recommendations into physical activity, resilience, oral health, management of non-communicable diseases, involvement in society, smoking cessation, and eating various kinds of food. Conclusion: Unlike previous frailty-related guidelines, this study developed evidence-based frailty prevention guidelines based on a systematic review. The guidelines are expected to contribute to the healthy aging of community-dwelling older adults by the primary prevention of frailty.
FINITELY GENERATED gr-MULTIPLICATION MODULES
Seungkook Park 충청수학회 2012 충청수학회지 Vol.25 No.4
In this paper, we investigate when gr-multiplication modules are ¯nitely generated and show that if M is a ¯nitely generated gr-multiplication R-module then there is a lattice iso-morphism between the lattice of all graded ideals I of R containing ann(M) and the lattice of all graded submodules of M.
SOME PROPERTIES OF GR-MULTIPLICATION MODULES
Park, Seungkook The Kangwon-Kyungki Mathematical Society 2012 한국수학논문집 Vol.20 No.3
In this paper, we provide the necessary and sufficient conditions for a faithful graded module to be a graded multiplication module and for a graded submodule of a faithful gr-multiplication to be gr-essential.

한국원자력연구원은 연구로 1, 2호기와 우라늄변환시설의 해체활동에서 얻어진 해체 경험과 그간에 쌓인 해체활동에 관한 정보 그리고 해체 대상 시설의 특성자료를 통하여 해체 작업 시 발생하는 유닛 생산성(Unit Productivity)을 자동으로 산출하는 시스템(DEWOCS)을 개발하였다. DEWOCS를 통한 해체작업 시 발생하는 유닛의 해체작업 생산성 평가 인자 값은 해체 엔지니어링 시스템의 개발 및 향후 이루어질 원자력발전소를 비롯한 원자력시설의 해체 사업에서 계획 및 해체 설계에 기초자료로써 활용될 것이다.

근래 들어 강화되는 배출가스 규제에 대응하기 위한 대책으로 LPG 차량에 적용되고 있는 제3세대 LPG 연료공급방식인 Lpi(Liquid phase LPG injection)는 펌프를 이용해서 고압의 액상연료를 공급하는 것이 가장 핵심적인 기술이다. Lpi 시스템은 액상연료분사의 전자식 정밀제어를 통해 출력이 상승하고 유해배출가스가 현저하게 저감되는 장점이 있으나, 가장 핵심적인 부품인 연료펌프 및 인젝터의 경우 대부분 수입에 의존하고 있어 시스템 설계에 유연하지 못하다. 본 연구에서는 인젝터의 국산화 개발을 위해 Lpi 시스템에 적합한 연료공급방법의 인젝터 디자인 및 최적의 작동조건 확보를 목표로 Lpi용 인젝터의 설계 및 시작품을 제작하여 누설 및 유량특성을 살펴보았다. In recent years, the need for more fuel-efficient and lower-emission vehicles has driven the technical development of alternative fuels such as Lpi (Liquid phase LPG injection) which uses pump for the high pressure supply of liquid LPG fuel and is able to meet the limits of better emission levels while it has an advantage of higher power. Although it has the advantage of power and lower emission levels, the characteristics of LPG, such as high vapor pressure, lower viscosity and surface tension than gasoline fuels makes it difficult design system. Therefore most fuel pumps and injectors are imported. In the present study, in order to domestically develop LPG injector which guarantees flow rates and optimal operation, the experimental investigation on leakage and flow rate characteristics of developed prototype injector was carried out at the bench test rig for developed injector.
