Background: A simple binary scoring system (SBSS) was developed and used to assess the welfare measures ofcommercial broiler chickens in South Korea. We also correlated welfare measures with environmental parameters ofbroiler house. Our measures of welfare included lameness, hock burn (HB) and foot pad dermatitis (FPD), whilstenvironmental parameters included air temperature, relative humidity, air speed, light intensity, air quality (inparticular carbon dioxide (CO2) and ammonia (NH3) concentrations) and airborne microbes. Results: The effect of environmental parameters on welfare measures was apparent even on 10-day-old broilers. Anon-parametric correlation analysis revealed significant correlations between environmental parameters and welfaremeasures. The key environmental parameters were relative humidity and light intensity. The results indicate thatthere is a need for proper control of environmental conditions on poultry farms, which could reduce health problemsand subsequently reduce disease and mortality. Conclusions: In conclusion, the simplicity of SBSS makes it preferable over more complex scoring systems and allowsa farmer to more easily assess the welfare measures on their own farm.

Background : Nowadays obesity has increased dramatically in developed countries which lead various metabolic disorders such as type 2 diabetes, hypertension, cancer, and the risk of stroke. Thus, looking forward a new chemical entity from natural sources which have a strong potential of anti-lipid regulation activity. Recently, protein based nanomedicine offers a new approach to treat a number of diseases including metabolic disorder such as obesity. In this study we evaluated the anti-lipid regulation effect of nano-carrier Bovine serum albumin and Mesoporous silica (MSNPs) conjugated ginsenoside F1 in 3T3-L1adipocytes and HepG2 hepatocytes. Methods and Results : BSA incorporated drugs has been shown to protect the drug degredation as well as improvement bioavalilability. To assess the anti- adipogenic effect of BSA-F1 and MSNPs-F1 cell viability was investigated in different time point of cell cycle growth and the intracellular lipid accumulation was evaluated in mature adipocytes and hepatocytes by Oil red staining assay. In addition, transcriptional gene regulation was quantified by the real time PCR for targeting adipogenic genes such as PPARγ, STAT3, CEBPα, ap2 and aP2 as well as hepatogenic genes such as ACC, AMPK, FAS and PPARα. Moreover, protein expression was evaluated by immunoblotting assay. Conclusion : Altogether, the above results were confirmed that BSA-F1 at dose 25 μM exhibited the anti-adipogenesis effect by downregulating the major transcriptional factors PPAR γ/STAT3 in signalling in 3T3-L1 mature adipocytes and upregulated the fatty acid oxidative AMPK signaling in fatty acid induced HepG2 hepatocytes.

본 논문은 BasicVSR 모델을 개량하여 특징 맵을 필터링할 수 있도록 개선된 모델을 제안한다. 기존 모델은 인접한 프레임을 바탕으로 학습하지만, 학습에 악영향을 끼칠 수 있는 특징까지 학습에 이용하는 단점이 있다. 따라서 기존 모델에 필터링 모듈을 추가하여 모델이 학습에 적절한 특징 맵을 선택하도록 개선한다. 필터링의 성능을 효과적으로 검증하기 위해 2D 애니메이션 동영상 데이터 세트를 사용한다. 필터링이 추가된 BasicVSR 모델은 AVC-Train 데이터 세트로 학습하며, AVC-Test 데이터 세트로 테스트한다. 성능 측정 지표 결과 필터링이 동영상 초해상화 모델의 학습에 효과적임을 알 수 있다.
