Changes of pupa powder ingestion on inflammatory cytokine in rats
여윤기,조미희,전병덕,서효빈,권태동,류승필 한국운동영양학회 2013 Physical Activity and Nutrition (Phys Act Nutr) Vol.17 No.3
Silkworm pupa (SP) contains high-quality protein. Therefore, in this study, silkworm pupa protein effects on immunity and antioxidant activity in skeletal muscle and liver were examined with 5-week SP fed rats (n = 32). They were divided into four groups as a group fed a normal diet (CON) with exercise training (EX), a group fed a silkworm pupa diet (PP) with an exercise training (PPEX). Liver MDA was also decreased in PP and PPEX compared to the CON. Liver and skeletal muscle SOD was enhanced both in exercise training and Silkworm Pupa diet. TNF-α, NF-κB and IL-6 in liver was suppressed in PP and PPEX. These results suggest that inflammatory cytokines were suppressed by silkworm pupa ingestion and/or exercise training that may inhibit the aging process effectively increasing antioxidant capacity in rats.

거푸집-동바리 시스템의 안전성에 영향을 미치는 시공현황 조사 및 분석
여윤기,김호수,정성진,곽순섭 대한건축학회 2001 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.21 No.2
Form-shore system is a temporary structure which the upper and lower joint of shore isn't tightly linked with the form and slab. In this case, the lateral forces caused by eccentric loading due to concrete placement paths, wind load, out-of-plumb shore and so on can occur large lateral displacements. Nevertheless, Structural engineers focus on ensuring only the safety of buildings during their service lives with considering the maximum wind load and seismic load, but they haven't been concerned about the safety check of temporary structure system during construction. The purpose of this paper is to present the construction method which can effectively decrease the lateral displacement by comparing and analyzing construction situations based on the actual site research with the investigation of construction criteria.
