Biotechnology will play critical role in improving animal productivity. Animal growth rate and muscle deposition potential can be greatly improved by the application of biotechnology and biotechnological products. Administration of recombinant somatotropin (ST) or other compounds such as IGF-1 and growth hormone-releasing peptides (GHRPs) can enhance growth rate and carcass lean percentage. Gene transfer offers a powerful approach to manipulate endocrine system and metabolic pathways toward faster growth and better feed efficiency. Biotechnology is also extensively used for improving metabolism and activity of gut microorganisms for better nutrient digestibility. Knockout of growth-inhibiting genes such as myostatin results in considerable acceleration of body weight and muscle growth. Animal growth can also be improved by the use of gene therapy. Immunomodulation is another approach for efficient growth through controlling the activity of endogenous anabolic hormones. All the above aspects will be discussed in this review.

Recent studies in molecular biology and proteomics have identified a significant number of novel diagnostic, prognostic, and therapeutic disease markers. However, validation of these markers in clinical specimens with traditional histopathological techniques involves low throughput and is time consuming and labor intensive. Tissue microarrays (TMAs) offer a means of combining tens to hundreds of specimens of tissue onto a single slide for simultaneous analysis. This capability is particularly pertinent in the field of cancer for target verification of data obtained from cDNA micro arrays and protein expression profiling of tissues, as well as in epidemiology-based investigations using histochemical/immunohistochemical staining or in situ hybridization. In combination with automated image analysis, TMA technology can be used in the global cellular network analysis of tissues. In particular, this potential has generated much excitement in cardiovascular disease research. The following review discusses recent advances in the construction and application of TMAs and the opportunity for developing novel, highly sensitive diagnostic tools for the early detection of cardiovascular disease.

The dairy industry has consistently grown via the expansion of dairy-based food categories. Dairy product consumption is stable since the nutrient composition in dairy products is ideal for human health. However, dairy products are highly susceptible to food-borne pathogens. Controlling the safety of dairy products is thus important when considering the nutrient-rich matrix of this food category. Currently, immunoassays or molecular biology techniques have been used to evaluate the safety of dairy products in Korea. These methods are based on the detection of proteins and thus have low reproducibility and sensitivity. Recent techniques to detect food-borne pathogens have focused on genetic analyses. Rapid detection methods for food-borne pathogens in milk and dairy products using polymerase chain reaction (PCR) techniques, such as conventional PCR, real-time PCR, repetitive sequence-based (rep)-PCR, PCR-denaturing gradient gel electrophoresis (DGGE), and digital PCR, are reviewed in this article. The aim of this review was to contribute knowledge of the relationship between microflora and the quality of dairy products. This study will also assist in the immediate monitoring of food-borne pathogens in milk and dairy products when an outbreak related to this food category occurs.

This research aims at the contribution to globalize and modernize the traditional Korean image by comprehending the taste of design that domestic college students have for traditional feminine head ornaments and subsequently elaborate the development of cultural products that are related to these decorative objects. In regards to this research method, the examination on the traditional feminine ornaments was followed through a review of literature and precedent studies and a survey was conducted on the preference about them. After the adoption of final valid responses, an analytical method, PASW 18.0, was used for frequency analysis, technical analysis, reliability, and regression analysis. The results were as follows. First, in the category of tendency analysis for the application of traditional feminine headpiece in fashion cultural products, it was revealed that a taste for the design that meet the satisfaction for both trend and practicability was prominently prevalent. Also, the design that express the individual characteristic was taken as a preferred option. Second, in the preference for the design of traditional feminine headpieces in fashion cultural products, the result indicated that the modern type was preferred in the form of re-creation as long as those products deform the tradition. As for the selective taste for patterns, their preference came in the order of plant, animal, and geometry-abstract types. Especially, for the case of plant and animal patterns, the reinterpreted design of modernized shapes were opted rather than a simply recopied format of the conventional type of the feminist head ornament. Third, for the category of item selection to apply the feminine head ornament in order to design the fashion cultural products, it turned out that people preferred the application to accessory rather than clothing. Lastly, it was found that rarity, harmony with other fashion goods, pattern, and design should be considered when the traditional motif was used for cultural products.

팬데믹(Pandemic)으로 인해 온라인 시장의 규모가 급속하게 커졌다. 일상에서의 비대면화는그동안 기술수용에 늦은 소비자마저 온라인구매의 편리함을 경험하게 하는 계기가 되었고, 이들은 팬데믹 이후에도 온라인구매의 이점을 선호하게 될 것이다. 하지만 이러한 변화의 시기에 소비자가 취할 수 있는 제품 정보는 편평한 디스플레이상의 시각적 정보만으로 축소되었다. 회사들은 차별적이고 경쟁력 있는 정보를 제공하기 위해 AR/VR, Streaming 기술 등을 도입하고 있지만, 정직한 사용자들이 남긴 리뷰는 회사가 제공하는 잘 가공된 정보만큼 소비자에게 강력하게 인식되고, 회사의 상품개발과 마케팅 및 판매 전략을 위한 인사이트를 얻을 수 있다는 점에서 중요하게 인식될 필요가 있다. 그렇다면 소비자의 입장에서, 구매 의사결정 전에 참고하는 리뷰의 평점이 크게 어긋난다면, 소비자들은 어떻게 리뷰정보를 처리할까? 수렴되지 않은 평점은 늘 신뢰할 수 없고 가치 없는 것일까? 본 연구에서는 소비자의 개인 성향으로 볼 수 있는 조절초점 성향이 어떻게 사고방식을 지배하여 수렴되지 않은 정보를 수용하고 처리하는지 보이고자 하였다. 실험은 화장품을 대상으로 제품 리뷰 평점의 분산(높음 vs 낮음)이 소비자의 조절초점(예방초점 vs. 향상초점)에 따라 제품 태도에 어떤 영향을 미치는지 2x2 연구로 설계하였다. 연구결과, 예방초점의 소비자는 분산이 작을 때 높은 제품 태도를 보이지만, 향상초점의 소비자는 분산이 클 때 높은 제품 태도를 보인다는 것을 발견하였다. 이와 같은 연구로, 본 논문은 동일한 평균값의 평가점수를 가진 제품이라도 후기의 분산 값에 따라 소비자의 조절초점 성향이 영향을 미쳐 제품 태도가 달라진다는 것을 설명할 수 있다. 본 논문은 평점이 수렴되지 않는 정보에 대한 소비자의 정보처리의 메커니즘을 밝힌 이론적 공헌이 있으며, 실무적으로 기업은 리뷰가 축적됨에 따라 개인화되고 최적화된 상품 정보를 제공하는 등 빅데이터를 바탕으로 지식경영을 응용한 고객경험설계가 가능함을 시사한다.

As one of traditional packaging materials, paper and paperboard are being more popular and beneficial thanks to their environmental sustainability and have been widely used in packaging applications, from light weight infusible tissue for tea/coffee bags to heavy duty boards for the distribution. Papermakers have to design the products having a desired customized function with their paper machine. Globally, the use of filler and pigment in papermaking is now a very common practice to meet the needs of customers. Many benefits can be achieved as a result of filler addition, which mainly includes cost and energy savings. The replacement of traditional mineral fillers and pigments with biodegradable and renewable carbohydrate polymers is a very interesting and promising research topic due to the concern of environmental impact. In this review paper, the use of traditional and novel carbohydrate fillers and pigments in cellulosic paper is highlighted. It is noteworthy that there are still some challenges and technical barriers associated with the use of these organic materials in point of structural stabilities and manufacturing costs, although most of them are available in market as the commercialized products. With the emerging nanotechnologies, it is believed that the use of carbohydrate-based filler and pigment for papermaking will increase and bring technical advantages to industry.
