Objective: This study was conducted to fathom the underlying mechanisms of nutrition intervention and redox sensitive transcription factors regulated by Antrodia cinnamomea fermented product (FAC) dietary supplementation in broiler chickens. Methods: Four hundreds d-old broilers (41±0.5 g/bird) assigned to 5 groups were examined after consuming control diet, or control diet replaced with 5% wheat bran (WB), 10% WB, 5% FAC, and 10% FAC. Liver mRNA expression of antioxidant, inflammatory and lipid metabolism pathways were analyzed. Prostaglandin E2 (PGE₂) concentration in each group were tested in the chicken peripheral blood mononuclear cells (cPBMCs) of 35-d old broilers to represent the stress level of the chickens. Furthermore, these cells were stimulated with 2,2'-Azobis(2-amidinopropane) dihydrochloride (AAPH) and lipopolysaccharide (LPS) to evaluate the cell stress tolerance by measuring cell viability and oxidative species. Results: Heme oxygenase-1, glutathione S-transferase, glutamate-cysteine ligase, catalytic subunit, and superoxide dismutase, and nuclear factor (erythroid-derived 2)-like 2 (Nrf2) that regulates the above antioxidant genes were all up-regulated significantly in FAC groups. Reactive oxygen species modulator protein 1 and NADPH oxygenase 1 were both rather down-regulated in 10% FAC group as comparison with two WB groups. Despite expressing higher level than control group, birds receiving diet containing FAC had significantly lower expression level in nuclear factor-kappa B (NF-κB) and other genes (inducible nitric oxide synthase, tumor necrosis factor-α, interleukin-1β, nucleotide-binding domain, leucine-richcontaining family, pyrin domain-containing-3, and cyclooxygenase 2) involving in inflammatory pathways. Additionally, except for 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase that showed relatively higher in both groups, the WB, lipoprotein lipase, Acetyl-CoA carboxylase, fatty acid synthase, fatty acid binding protein, fatty acid desaturase 2 and peroxisome proliferator-activated receptor alpha genes were expressed at higher levels in 10% FAC group. In support of above results, promoted Nrf2 and inhibited NF-κB nuclear translocation in chicken liver were found in FAC containing groups. H₂O₂ and NO levels induced by LPS and AAPH in cPBMCs were compromised in FAC containing diet. In 35-d-old birds, PGE₂ production in cPBMCs was also suppressed by the FAC diet. Conclusion: FAC may promote Nrf2 antioxidant pathway and positively regulate lipid metabolism, both are potential inhibitor of NF-κB inflammatory pathway.

본 연구에서는 소와 조사료로 이용되고 있는 볏짚의 농약잔류량 모니터링 결과 검출된 edifenphos와 tricyclazole에 대해 확률적 접근법을 이용해 축산물 중 잔류하는 농약의 우리나라 국민 전체에 대한 노출량을 예측하고 ADI와 비교한 위해성평가를 수행하였다. 평가 결과 소부산물을 간으로만 섭취할 경우 전체인구의 edifenphos 평균 노출량은 ADI대비 0.027%로 매우 낮았으며 $99%^{th}$에서도 0.034% 수준으로 안전하였다. 연령층 별로 볼 때 부산물의 섭취량이 매우 낮은 1~6세가 가장 안전하였으며 부산물의 섭취가 많은 19~29세의 평균 노출량이 ADI대비 0.04%로 상대적으로 높았으나 이 또한 매우 낮은 수준으로 소부산물 섭취를 통한 edifenphos의 위해성은 모든 연령층에서 낮은 것으로 평가되었다. Tricyclazole은 볏짚에 잔류하는 수준이 낮으므로 간 및 신장을 포함한 소부산물 중 잔류량이 음의 값으로 계산되어, 소부산물 중 농약잔류량을 정량한계의 1/2을 적용하여 점추정으로 평가하였다. 소부산물 섭취에 의한 전체인구의 tricyclazole 평균 노출량은 ADI대비 0.0006%로 매우 낮았으며 $99%^{th}$에서도 0.0007%로 아주 미미한 수준이었다. 연령층 별 tricyclazole의 ADI대비 노출량은 $99%^{th}$에서도 1~2세의 0.0003%부터 19~29세의 0.0013%까지 분포하여 소부산물 섭취를 통한 tricyclazole의 위해성은 모든 연령층에서 매우 낮은 것으로 평가되었다.

이미지에 대한 연구는 그동안 사회학, 심리학 및 마케팅 분야 등에서 행해져 왔으나 각 분야의 연구의도나 목적에 맞는 이미지 개념을 적용시켜 왔기 때문에 이미지에 대한 공통적인 개념을 규정하기는 쉽지 않다. 최근 감성공학에서 출발한 감성평가를 통해 제품의 이미지를 객관적으로 평가하려는 노력들이 시도되고 있다. 본 연구는 우리나라 중년 여성들의 라이프 스타일을 몇 가지 유형으로 분류한 후, 이에 따른 패션제품에 대한 이미지 선호도를 밝히고자 하였다. 연구 방법은 선행 자료의 분석을 통한 문헌연구와 설문지법을 통한 실증 연구를 병행하였다. 연구 대상은 만 35$\sim$59세 여성으로, 총 352부의 자료를 분석에 사용하였다. SPSS 11.0과 SAS for program 8.1 version을 이용하여 통계처리 하였다. 그 결과 패션 제품에 대한 이미지를 품위성, 대담성, 실용성, 여성성의 4개 인자로 하였다. 또 라이프스타일의 유형을 전통보수형, 소극정체형, 적극생활형, 외모중시형의 4개 집단으로 분류하였다. 분류된 라이프스타일 유형에 따라 선호하는 패션제품에 대한 이미지를 살펴 본 결과 전통보수형은 품위 있으며 실용적인 이미지의 패션 제품을 선호하였고, 소극정체형은 모든 패션 제품에 흥미를 보이지 않으나 여성스러움을 다소 추구하였다. 적극생활형은 대담한 이미지의 패션 제품을 선호하였으며, 외모과시형은 여성스러우며 다소 품위 있고 대담한 이미지를 선호하였다.

Hyperglycemia in the diabetic state increases oxidative stress and antioxidant therapy can be strongly correlated with decreased risks for diabetic complications. The purpose of this study is to determine antioxidant effect of garlic and aged black garlic in animal model of type 2 diabetes. The antioxidant activity of garlic and aged black garlic was measured as the activity in scavenging free radicals by the trolox equivalent antioxidant capacity (TEAC) assay. Three week-old db/db mice were fed AIN-93G diet or diet containing 5% freeze-dried garlic or aged black garlic for 7 weeks after 1 week of adaptation. Hepatic levels of lipid peroxides and activities of antioxidant enzymes were measured. TEAC values of garlic and aged black garlic were $13.3{\pm}0.5$ and $59.2{\pm}0.8{\mu}mol/g$ wet weight, respectively. Consumption of aged black garlic significantly decreased hepatic thiobarbituric acid reactive substances (TBARS) level compared with the garlic group which showed lower TBARS level than control group (p<0.05). Activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) of garlic and aged black garlic group were significantly elevated compared to the control group. Catalase (CAT) activity of aged black garlic group was increased compared with the control group. These results show that aged black garlic exerts stronger antioxidant activity than garlic in vitro and in vivo, suggesting garlic and aged black garlic, to a greater extent, could be useful in preventing diabetic complications.

본 연구팀에서 개발한 키틴분해미생물 대량배양 bioformulated product는 다양한 작물의 병과 선충의 생물적 방제에 성공적으로 이용되어 왔다. 이 연구에서는 개발된 키틴분해미생물 대량배양 기술을 활용하여 인삼 모잘록병의 생물적 방제법을 확립하고자 수행하였다. 인삼 잘록병 오염 토양을 이용한 포트에서 키틴최소배지에서 배양한 키틴분해미생물 Chrobacterium sp.와 L. enzymogenes 혼합배양액 처리구에는 인삼의 출아율과 인삼 잘록병율이 통계적으로 유의하게 감소하였다. 개발된 키틴분해미생물 배양액의 생물적 방제 능력은 희석여부와 처리시기에 따라 차이를 보였다. 인삼 포장에서 혼합배양액을 파종 전 종자침지하고 출아기에는 토양관주하였을 때, 본포의 2년생 인삼에서 배양원액은 2회 토양관주, 10배 희석액은 3회 토양관주에서 높은 방제효과를 나타냈다. 토직 본포의 경우 배양 원액의 종자 침지에 의한 방제효과는 낮았지만, 종자침지 후 1회 또는 2회 토양관주는 살균제인 톨클로로포스메틸수화제의 종자분의소독과 비슷한 수준의 방제효과를 보였다. 이러한 결과는 Chromobacterium sp. C-61와 L. enzymogenes C-3의 혼합배양액을 이용하여 인삼 잘록병 방제에 화학적 살균제를 대신할 수 있을 효과적인 대안이 될 수 있을 것이다.

Objective: Enterotypes (ETs) are the clustering of gut microbial community structures, which could serve as indicators of growth performance and carcass traits. However, ETs have been sparsely investigated in waterfowl. The objective of this study was to identify the ileal ETs and explore the correlation of the ETs with growth performance and carcass traits in Muscovy ducks. Methods: A total of 200 Muscovy ducks were randomly selected from a population of 5,000 ducks at 70-day old, weighed and slaughtered. The growth performance and carcass traits, including body weight, dressed weight and evidenced weight, dressed percentage, percentage of apparent yield, breast muscle weight, leg muscle weight, percentage of leg muscle and percentage of breast muscle, were determined. The contents of ileum were collected for the isolation of DNA and 16S rRNA gene sequencing. The ETs were identified based on the 16S rRNA gene sequencing data and the correlation of the ETs with growth performance and carcass traits was performed by Spearman correlation analysis. Results: Three ETs (ET1, ET2, and ET3) were observed in the ileal microbiota of Muscovy ducks with significant differences in number of features and α-diversity among these ETs (p<0.05). Streptococcus, Candida Arthritis, and Bacteroidetes were the presentative genus in ET1 to ET3, respectively. Correlation analysis revealed that Lactococcus and Bradyrhizobium were significantly correlated with percentage of eviscerated yield and leg muscle weight (p<0.05) while ETs were found to have a close association with percentage of eviscerated yield, leg muscle weight, and percentage of leg muscle in Muscovy ducks. However, the growth performance of ducks with different ETs did not show significant difference (p>0.05). Lactococcus were found to be significantly correlated with leg muscle weight, dressed weight, and percentage of eviscerated yield. Conclusion: Our findings revealed a substantial variation in carcass traits associated with ETs in Muscovy ducks. It is implied that ETs might have the potential to serve as a valuable biomarker for assessing duck carcass traits. It would provide novel insights into the interaction of gut microbiota with growth performance and carcass traits of ducks.

The purpose of this study is to investigate, analyze the purchasing behavior of fashion goods according to life style and role model of preteen generation, and provide manager or marketing planner for the reference data so that they can understand preteen generation and make proper strategy efficiently. So called, preteen market focusing on 1014 generation (from ten to fourteen years old) is highlighted. This generation created between the year 1989 to 1993 after Seoul Olympic monopolize parent's love in abundant economic environment and rise to the core of consumption subject. Products aiming at this preteen generation continuously though consumption mind was shrunk greatly due to recession. Only 2~3 years before preteen market was regarded as grey zone which doesn't belong to not only children (between six and nine years old) but also teenagers (between fifteen to eighteen years old). But in recent day their purchasing powers have increased rapidly and age group is divided on details, so that preteen market has become a niche market. Subjects were 333 persons consisting of students in the 4th~6th grade of primary school and the 1st~2nd grade of middle school in Daegu city. Measuring instruments are as follows: 5questions to differentiate preteen generation, 22 questions to measure life style, 17questions (which have six sub-factors such as purchase motive, factor of product selection, utilization of informant, purchase time, purchase place, and purchase method) to measure the purchase behavior of fashion goods measurement, and 16 questions (which have four sub-factors such as parent, entertainer & sports stars, brothers and sisters, friends) to measure model of role. Statistical data were processed by SPSS 10.0 programs. Frequencies, Factor analysis, Cluster analysis, ANOVA, Cross analysis, Multiplex regression analysis, and Duncan's multiple range test were carried out.
