최근 들어, 소셜 네트워크 서비스를 통한 멀티미디어 콘텐츠의 열람과 공유가 보편화됨에 따라, 사용자의 관심이나 특징에 부합되는 콘텐츠의 효과적 제공에 대한 욕구가 높아지고 있다. 특히, 생성되는 콘텐츠의 방대한 양을 고려할 때 적합한 콘텐츠의 효과적 선택이 사용자의 만족도를 크게 좌우하게 된다. 예를 들어, 사람간의 관계에 기반하여 관심 콘텐츠를 제공하는 방법의 경우 신뢰성이 어느 정도 보장되기 때문에, 사용자의 효과적인 열람이 가능하다. 대표적인 소셜 네트워크 서비스인 Facebook에서 제공하는 Facebook 페이지는 관심사에 대한 콘텐츠를 획득할 수 있는 공간이지만, 사용자는 제공되는 콘텐츠의 양이 너무 많아 원하는 목적에 맞게 콘텐츠를 획득하기 어렵다. 본 논문에서는, 개인 사용자의 관심에 따라 Facebook 페이지 콘텐츠를 순위별로 선정하여 대표 콘텐츠를 제공하는 기법을 제안한다. 사용자 간의 친밀도를 이용해 사용자를 관심 분야에 따라 그룹화하고, 그룹화 된 사용자들에게 Facebook 페이지 콘텐츠를 중요도 순위별로 선택하여 사용자에 제공한다. 마지막으로 실험을 통해 제안된 기법의 성능을 보인다.

The purpose of this study is to find trends in new media fashion content by analyzing the fashion content of the official Instagram accounts of domestic fashion magazines that are being transformed by digital media. The framework for these analysis of fashion content type and methods of production is based on one used in an earlier research project. Empirical analysis is conducted on Vogue Korea's official Instagram accounts, using the highest number of major views as the secondary measure of interest. After screening for fashion content in posts on the Vogue Korea account for four months, 291 short video postings were extracted to analyze the number of views the postings received. The results were categorized as 'star', 'show/exhibition', 'product', 'shop', 'fashion film', 'designer', or 'event', included in the data are the number of postings by type and the number of views by post. Based on the characteristics of the creator and the editing, the posts were classified into 'professional production highlight', 'professional production private', 'UCC' or 'GIF' videos, the number of views per post were also collected. The research results show different levels of interest depending on the type of fashion content, and also on the way the videos were produced. The study also investigated how the combination of these two factors affects interest. When producing a new media fashion content, combining a 'star' type post with 'professional production private' video content was most popular. The selection of production method is therefore important even given the same type of content.

Objective: The aim of the study was to find a possible association between the ${\beta}-$ and ${\kappa}-casein$ and ${\beta}-lactoglobulin$ genotypes and important milk physiochemical and technological characteristics such as acidity, alcohol stability, the contents of some minerals and the parameters of acid fermentation ability (FEA) in Czech Fleckvieh Cattle. Methods: Milk and blood samples were collected from 338 primiparous Czech Fleckvieh cows at the same stage of lactation. The genotypes of individual cows for ${\kappa}-casein$ (alleles A, B, and E) and ${\beta}-lactoglobulin$ (alleles A and B) were ascertained by polymerase chain reaction-restriction fragment length polymorphism, while their ${\beta}-casein$ (alleles $A^1$, $A^2$, $A^3$, and B) genotype was determined using melting curve genotyping analysis. The data collected were i) milk traits including active acidity (pH), titratable acidity (TA), alcohol stability (AS); calcium (Ca), phosphorus (P), sodium (Na), magnesium (Mg), and potassium (K) contents; and ii) yoghurt traits including active acidity (Y-pH), titratable acidity (Y-TA), and the counts of both Lactobacilli and Streptococci in 1 mL of yoghurt. A linear model was assumed with fixed effects of herd, year, and season of calving, an effect of the age of the cow at first calving and effects of the casein and lactoglobulin genotypes of ${\beta}-CN$ (${\beta}-casein$, CSN2), ${\kappa}-CN$ (${\kappa}-casein$, CSN3), and ${\beta}-LG$ (${\beta}-lactoglobulin$, LGB), or the three-way interaction between those genes. Results: The genetic polymorphisms were related to the milk TA, AS, content of P and Ca, Y-pH and Lactobacilli number in the fresh yoghurt. The CSN3 genotype was significantly associated with milk AS (p<0.05). The effect of the composite CSN2-CSN3-LGB genotype on the investigated traits mostly reflected the effects of the individual genes. It significantly influenced TA (p<0.01), Y-pH (p<0.05) and the log of the Lactobacilli count (p<0.05). Conclusion: Our findings indicate that the yoghurt fermentation test together with milk proteins genotyping could contribute to milk quality control and highlight new perspectives in dairy cattle selection.
