        본 연구는 간호사의 스트레스, 스트레스 증상 및 이직의도를 비교하기 위한 서술적 조사 연구이다. 연구대상자는 대상자는 D시에 소재한 2개 대학교병원 간호사 183명을 대상으로 하였으며 2018년 9월 1일부터 12월 1일까 까지 실시되었다. 자료분석은 SPSS 22.0 프로그램을 이용하였으며, 빈도와 백분율, 평 균, 표준편차, t-test, ANOVA, correlation를 이용하였다. 본 연구결과 대상자의 스트레스는 평균이 95.05±10.21점, 스트레스 증상은 200.02±50.73점, 이직의도는 39.591±8.3점 이었고, 스트레스가 증가할수록 스트레스 증상과 이직의도가 증가하는 것으로 나타났다. 이상의 결과로 간호사의 스트레스 감소를 위한 다학재적 지원 방안이 필요한 실정이며, 본 연구 결과는 간호 인력의 효율적인 운용을 위해 기초자료로서 유용하게 활용될 수 있을 것이다.

        Foot-and-mouth disease (FMD) has great potential for causing huge economic loss and was the first disease identified by the World Organisation for Animal Health (OIE) in its official list of free countries and zones. This study examined the governmental expenditures for five FMD epidemics that occurred in the Republic of Korea between 2000 and 2011. The costs of an epidemic ranged from 26 billion Korean won (KRW, approximately 23.6 million US dollars, ) to a maximum of 2,044 billion KRW (US 1.9 billion). For two epidemics in which vaccinations were implemented, the costs were higher than those epidemics without vaccination. The mean cost for an outbreak ranged from 0.5 billion KRW (US 4.5 million) for the 2010/2011 epidemic to 18.2 billion KRW (US 16.5 million) for the 2000 epidemic. Mean costs per infected premises were 7.0 billion KRW for cattle farms (95% CI: 4.72∼9.28), 1.38 billion KRW for pig farms (0.88∼1.87), 0.11 billion KRW for deer farms (0.08∼0.14), and 0.10 billion KRW for goat farms (0.07∼0.13). The highest cost for an outbreak in cattle seemed associated with the number of outbreak cattle farms in two epidemics in which vaccination was implemented.

        Cynanchum wilfordii Radix (CWR), Arctium lappa L (ALL), and Dioscorea opposite (DO) have been known to improve blood lipid profile, blood pressure, and inflammation. To find the optimal combination ratio of CWR, ALL, and DO in terms of vascular health improvement, we compared the effects of various combinations on gene expression of Vascular cell adhesion protein 1 (VCAM-1) in human aortic smooth muscle cells (HASMC). VCAM-1 mediates endothelial leukocyte adhesion and is upregulated in atherosclerosis. Cells was stimulated by TNF-α (10 ng/㎖, 2h) and treated with various combinations for 24 h. A combination (CADM5, CWR:ALL:DO = 2:1:1) showed the strongest suppression of VCAM-1 so that CADM5 was chosen for further experiments. We performed cell viability test with CADM5 (0, 3.125, 12.5, 25, 50, and 100 ㎍/㎖) and no cytotoxicity was found. We also investigated the effect of CADM5 on protein expression of VCAM-1, ICAM-1, Nrf-2, and HO-1 using western blotting. We found that CADM5 diminished the expression of VCAM-1 and increased the expression of Nrf-2 and HO-1. Therefore, we concluded that CADM5 (CWR:ALL:DO = 2:1:1) effectively improves vascular health by regulating the expression of VCAM-1.

        Osteoarthritis (OA) is a degenerative disease characterized by the progressive degradation of joint cartilage and is accompanied by secondary inflammation of synovial membranes. The purpose of this study describes a preliminary evaluation of the anti-inflammatory activity on test material of Litsea japonica. fruit (LJTM) Also, this study was to evaluate the effects of LJTM on the joint cartilage of rat with OA induced by monosodium iodoacetate (MIA). To study for anti-inflammatory agents effectively, we first examined the inhibitory effect of the LJTM on the production of pro-inflammatory factors and cytokines stimulated with lipopolysaccharide. We identified anti-nociceptive effects of the LJTM by using in vivo peripheral and central nervous pain models. In addition, the aim of this study was to evaluate the effects on mRNA expression of MMP-2, -3, -7, -9, -13, TIMP-1 and –2 in cartilage of OA. In the LJTM inhibited production of pro-inflammatory mediators (NO and PGE2) and pro-inflammatory cytokines (TNF-α and IL-6). In cartilage, Expression of MMPs and TIMPs mRNA was suppressed in LJTM treatment group than in the control group. This study suggests that LJTM are potential candidates as anti-inflammation and anti-osteoarthritis agents (painkillers) for the treatment of OA.
