Flavor is an important sensory trait of chicken meat. The free amino acid (FAA) and nucleotide (NT) components of meat are major factors affecting meat flavor during the cooking process. As a genetic approach to improve meat flavor, we performed a genome-wide association study (GWAS) to identify the potential candidate genes related to the FAA and NT components of chicken breast meat. Measurements of FAA and NT components were recorded at the age of 10 weeks from 764 and 767 birds, respectively, using a White leghorn and Yeonsan ogye crossbred F2 chicken population. For genotyping, we used 60K Illumina single-nucleotide polymorphism (SNP) chips. We found a total of nine significant SNPs for five FAA traits (arginine, glycine, lysine, threonine content, and the essential FAAs and one NT trait (inosine content), and six significant genomic regions were identified, including three regions shared among the essential FAAs, arginine, and inosine content traits. A list of potential candidate genes in significant genomic regions was detected, including the KCNRG, KCNIP4, HOXA3, THSD7B, and MMUT genes. The essential FAAs had significant gene regions the same as arginine. The genes related to arginine content were involved in nitric oxide metabolism, while the inosine content was possibly affected by insulin activity. Moreover, the threonine content could be related to methylmalonyl-CoA mutase. The genes and SNPs identified in this study might be useful markers in chicken selection and breeding for chicken meat flavor.

현재 모바일콘텐츠 분류체계는 분류원칙에 위배되는 구조적 문제와 컨버전스에 기인한 서비스의 다양화를 수용하는데 한계를 드러낸다. 본 연구는 이러한 한계점의 극복방안으로 알리스(Al Ries)의 이론을 발전시킨 대칭형과 비대칭형의 분류기준을 적용한 새로운 모바일콘텐츠 분류체계를 제시 한다. 여기서 대칭형은 융합 과정에서 변이(變異)되어 새로운 형태의 모바일 콘텐츠가 생성되는 것을 의미하는 반면, 비대칭형은 독립적인 속성들이 유지된 채 융합된 조합(組合)을 의미한다. 제시된 분류체계를 적용하여 현(現) 모바일 콘텐츠를 분석하면 모바일 콘텐츠 개발 및 서비스가 대칭형을 지향하고 있다는 사실과 기술의 발전과 함께 과거의 비대칭형 모바일 콘텐츠 역시 대칭형으로 재개발 되고 있다는 콘텐츠 산업의 경향이 도출된다. 현재 모바일 콘텐츠는 대칭적 성향과 비대칭적 성향이 공존한다는 측면에서 모바일콘텐츠 분류에 있어 대칭형과 비대칭형의 개념적 분류는 당분간 요구된다고 볼 수 있다. 따라서 본 연구에서 도출된 모바일 분류체계는 모바일콘텐츠 관련 연구자에게 컨버전스 경향은 물론 속성을 비교 분석할 수 있는 근거를 제공하는 동시에 모바일콘텐츠 관련 개발전략과 포지셔닝(Positioning) 전략을 세울 수 있는 일정정도 방향성 및 토대를 제시한다고 볼 수 있다.

The impact of raindrops on the soil surface causes soil detachment, which may be estimated by measuring the kinetic energy (KE) of the raindrops. Since direct measurements of rainfall force on ground surfaces are not generally available, empirical equations are an alternative option to estimate KE from rainfall intensity (I), which has the greatest influence over soil erosion and is easily accessible. Establishing the optimal formulation for the relationship between kinetic energy and rainfall intensity has proven to be difficult. Thus, this research considered thirty-seven rainfall events observed from June 2020 to December 2021 using a laster optical disdrometer erected in Kyungpook National University to examine the characteristics of KE-I relationships. We concentrated our discussion on the formation of two different expressions of the KE, including KE expenditure (KE_exp) and KE content (KE_con). The following conclusions were drawn: (1) We employed statistical analysis to demonstrate that the KE_exp is more suitable expression for establishing an empirical rule between KE and I than the KE_con. (2) A power-law model was used to find the best correlation between KE_exp-I relationship, whereas the best match between KE_con and I were found using an exponential equation.

The experiment was carried out to study the effect of Korean wild ginseng adventitious root supplementation on the laying performance, egg quality, cytokine expression, ginsenoside concentration, and microflora quantity of Institut de selection Animale (ISA) brown laying hens at 24 weeks old. A total of 90 laying hens were subjected to a completely randomized design at three treatments, five repetitions and six laying hens per replicate. The experiments were divided by diets into the basic feed (CON), basic feed + 0.1% wild ginseng (WG1), and basic feed + 0.5% wild ginseng (WG2). The feeding trial was carried out over a duration of 12 weeks after an initial acclimation period of 2 weeks. Feeds and water were administered ad libitum in mash form, and light was available for 16 hours per day. At the end of study, henday egg production (HDEP), average egg weight (AEW), and egg mass (EM) were increased (p <0.05) in WG2 at week 12. Feed conversion ratio (FCR) was decreased (p < 0.05) in WG2 at week 12. The ginsenoside content in egg yolk was increased (p <0.05) in laying hens in the WG2 treatment at week 12. Relative expression of tumor necrosis factor alpha (TNF-α) was reduced (p < 0.05) in the WG supplemented diets at week 12. The fecal microflora quantity of Lactobacillus was increased (p < 0.05) in WG2 at week 8 to week 12, and Escherichia coli (E. coli) was significantly decreased (p < 0.05) in the WG2 at week 12. We concluded that the result observed in the HDEP, AEW, EM and FCR was due to an increase in ginsenoside content, leading to an improvement in the TNF-α, and fecal microflora quantity such as Lactobacillus and E. coli in the WG2 supplemented diets. We therefore recommend the use of WG at application level 0.5% per basal diet for optimum laying performance in layer hens.
