Mastitis is a common and serious infection of the mammary gland in dairy cattle and has a major economic impact on the production of milk and dairy products. Bacterial mastitis is caused by several pathogens and is most frequently associated with coagulase-negative staphylococci (CNS). Although CNS are typically associated with subclinical or mild mastitis, the importance of CNS has increased as these pathogens have emerged as predominant mastitis-related pathogens in many countries. CNS can cause persistent infections, resulting in increased milk somatic cell counts and thereby affecting milk quality and decreasing milk production. Globally, Staphylococcus chromogenes, S. epidermidis, and S. simulans are the predominant CNS species in dairy cattle mastitis. Antibacterial resistance of CNS varies with species, and most CNS are susceptible to vancomycin and resistant to penicillin and tetracycline. As the most frequently isolated CNS species, some strains of S. chromogenes exhibit phenotypic resistance to ampicillin, erythromycin, oxacillin, penicillin, and tetracycline. Some strains of S. epidermidis and S. haemolyticus are only susceptible to vancomycin and rifampicin. Therefore, more studies are needed to achieve the control and prevention of CNS as environmental pathogens.

Cheese is an excellent substrate for yeast and mold growth. These organisms can cause cheese spoilage, resulting in significant food wastage and economic losses. In the context of cheese spoilage, the presence and effects of spoilage or pathogenic bacteria are well documented. In contrast, although yeasts and molds are responsible for much dairy food wastage, only a few studies have examined the diversity of spoilage fungi. This article reviews the spoilage yeasts and molds affecting cheeses in various countries. The diversity and number of fungi present were found to depend on the type of cheese. Important fungi growing on cheese include Candida spp., Galactomyces spp., Debaryomyces spp., Yarrowia spp., Penicillium spp., Aspergillus spp., Cladosporium spp., Geotrichum spp., Mucor spp., and Trichoderma spp.. In addition, several mold spoilage species, such as Aspergillus spp. and Penicillium spp., are able to produce mycotoxins, which may also be toxic to humans. There are many ways to eliminate or reduce toxin levels in foods and feeds. However, the best way to avoid mycotoxins in cheese is to prevent mold contamination since there are limitations to mold degradation or detoxifications in cheese. Chemical preservatives, natural products, and modified atmosphere packaging have been used to prevent or delay mold spoilage and improve product shelf life and food safety.

Bacteriocins are ribosomally synthesized proteinaceous substances produced by bacteria. They exhibit antimicrobial activity against closely related species and food-borne pathogens. Those produced by lactic acid bacteria (LAB) suggest a new direction for food preservation as they are often employed in food processing and food fermentations as natural biopreservatives. However, this new market demands the development of new downstream strategies to maximize its efficiency and economics. Aqueous two-phase system (ATPS) is a liquid-liquid fractionation technique, which has emerged as a powerful tool for the efficient extraction and purification of peptides, enzymes, and proteins due to its versatility, lower cost, process integration capability, and ease to scale-up. In this review, we introduce polymer-salt ATPS and surfactant-assisted ATPS for bacteriocin separation and provide an overview of the effects of parameters such as tie line length, pH, and properties of polymers and salts.

연구배경 모바일 뱅킹 애플리케이션 디자인을 설계할 때 UI 디자인의 사용자 경험 통일을 위해 앱 내 일관성 유지가 요구되며, 애플리케이션의 사용성을 높이기 위해 모바일 운영체제의 아이콘을 가이드라인에 따라 비교 분석하기 위한 기초 자료가 필요하다. 연구방법 선행 연구를 통해 머티리얼 디자인에서 내비게이션 디자인 아이콘을 설계할 때 필요한 제작 지침을 항목별로 파악하였다. 그중 안드로이드의 애플리케이션 제작과 관련 없는 항목을 제외한 후 설계 원칙, 그리드 및 키라인 모양, 시스템 아이콘 구조, 컬러로 구분하여 세부지침에 따른 수치를 측정했다. 그래서 대상 아이콘에 대한 측정 수치가 머티리얼 디자인의 시스템 아이콘제작 지침과 비교했을 때 어떤 차이가 있는지를 살펴보았다. 연구결과 설계 원칙에서 지침에 부합하는 대상과 그렇지 않은 대상의 비율이 비슷하게 나타났다. 그리드 및 키라인 모양에서 사이즈 항목이 모두 일치하지 않으나 레이아웃, 키라인, 선명도는 모두 일치하였다. 시스템 아이콘 구조에서는 모서리 반경이 모두 일치하지 않았고, 선은 대부분 일치하지 않았다. 복합적 형태는 대부분 일치하고, 여백은 모두 일치하였다. 컬러는 원칙에 부합하는 대상이 없었다. 결론 본 연구는 안드로이드의 모바일 뱅킹 애플리케이션을 설계할 때 머티리얼 디자인 제작 지침에 따라 아이콘을 설계하고 보완하는 방법을 제시하였다. 이를 통해 애플리케이션 내의 아이콘 디자인의 문제점을 파악하여 개선하는 데 도움이 될 것이다. Background When designing a mobile banking application, it is required to maintain consistency within the app to unify the user experience of the UI design, and in oorder to increase the usability of the application, basic data are needed to compare and analyze the icons of the mobile operating system according to the guidelines. Methods Through prior research, we identified the necessary production guidelines for each item when designing a navigation design icon for Material Design. Among these items, several items not related to Android application creation were excluded. Based on the derived material design icon creation guidelines, the icons of the target application's Bottom Navigation Bar were classified into design principles, grid and keyline shapes, system icon structures, and colors, and measured values according to detailed guidelines. Then, we checked whether there were any differences in the measurement values for the target icon compared to the material design system icon creation guidelines. Result In the design principle, the proportions of those who meet the guidelines and those who do not appear similar. In the shape of the grid and the key line, the size items did not all match, but the layout, key line, and sharpness all matched. In the system icon structure, all corner radii did not coincide, and most of the lines did not coincide. Most of the complex forms coincide, and all the margins coincide. There was no object in color that met the principle. Conclusion This study proposed a method to design and supplement icons according to the material design production guidelines when designing Android mobile banking applications. This will help to identify and improve icon design problems within the application.

김종희 ( Jong-hee Kim ),이화세 ( Hwa-sei Lee ) 한국디자인트렌드학회 2017 한국디자인포럼 Vol.56 No.-

연구배경 최근 다양한 디바이스의 스크린 환경에서 해상도 및 레이아웃 등이 유동적으로 변환되어 최적화될수 있도록 제작하는 반응형 웹이 사용되고 있다. 반응형 웹에서 이러한 가변적 레이아웃의 요소들을 조화롭게 시각화하기 위해서는 그리드의 체계적 구성에 대한 연구가 필요하다. 연구방법 반응형 웹의 그리드 설계시에 레이아웃 요소를 조화롭게 시각화시키기 위해서 시각 중심을 고려하여 디자인할 수 있는 방법을 제시하고자 하였다. 먼저 그리드의 유형과 패턴에 대해 살펴본 후, 이론적 시각중심과 실제 시각 중심에 대한 관계를 정립하여 반응형 웹에서 시각 중심을 도출할 수 있는 수식을 설정하였다. 설정된 수식을 바탕으로 반응형으로 제작된 웹사이트들의 실제 중심점의 좌표값을 미디어 쿼리의 변환 시점별로 도출하였다. 그 결괏값이 이론적 시각 중심점과 비교하여 얼마나 적합하게 제작이 되었는지를 알아보았다. 연구결과 비교한 웹 사이트들의 실제 시각 중심점들은 왼쪽 상단으로 위치해야 한다는 이론적 시각 중심점들과 일치되지 않았다. 그래서 그 차이 값이 가장 작도록 반응형 웹을 구축하면 시지각 이론의 시각 중심점에 맞게 설계된 것으로 볼 수 있고 이렇게 하면 사용자의 시선과 주목성을 만족할 수 있을 것이다. 결론 본 연구는 반응형 웹 디자인 설계시 이러한 레이아웃에 시각 중심점의 원리를 적용하는 방법을 제시함으로써 사용자의 시선을 올바르게 유도하여 혼돈을 주지 않는 인터페이스 설계가 가능할 것이다. Background Recently, Responsive Web is being used to ensure that the resolution and layout of a variety of devices are converted and optimized in a wide variety of devices. Research on the composition of the grid is needed to coordinate and visualize the elements of these variable layouts in the responsive web. Methods In the design of the responsive Web Grid, we wanted to propose a way to design a visual center in order to visualize the layout of the layout elements. We looked at the types and patterns of the grid and, then established the relationship between the theoretical visual centers and the actual visual center, and set the formula to derive the visual center coordinates. Based on the set formulas, we calculated the coordinate values of the actual visual centers of the web sites according to the conversion times of Media Query, and compared them to see how well the final values were produced in the theoretical visual center. Result The actual visual centers of websites compared to the above were not consistent with the theoretical visual centres that should be located in the upper left-hand corner. Thus, deigning a reponsive web site to the smallest of the values will be designed to match the visual center of visual perception theory, which will satisfy the user`s gaze and attention. Conclusion This study suggests how to apply the principle of visual center to this layout in designing Responsive Web design and by doing so, it will be possible to design an interface that guides the user`s gaze correctly and does not cause confusion.

반응형 웹 매거진의 디자인 요소 분석 - 패션·시사 잡지를 중심으로 -

김종희 ( Kim Jong-hee ),이화세 ( Lee Hwa-sei ) 한국디자인트렌드학회 2015 한국디자인포럼 Vol.47 No.-

모바일 인터넷의 발전으로 웹 서비스를 이용하는 방법 또한 다양한 스마트 디바이스들을 이용하는 유동적인 형태로 진화되었다. 지속적으로 쏟아져 나오는 새로운 디바이스들의 인터페이스에 유연하게 서비스 가능한 웹 디자인이 요구되고 있다. 다양한 스마트 디바이스에서 웹 매거진에서 서비스의 개선은 물론이고 제작 단계에서의 효율성을 높이고, 동일한 사용자 경험과 최적화된 서비스 제공하는 반응형 웹 제작 기술이 필요하다. 이를 위해 웹 매거진의 유형을 비주얼 리딩형과 텍스트 리딩형으로 분류하고, 패션잡지와 시사잡지를 중심으로 웹 매거진의 디자인 요소와 멀티미디어 요소를 살펴보고 각 세부 요소의 반응 형태를 비교하였다. 비주얼 리딩형 웹 매거진은 이미지 중심의 콘텐츠와 단순한 그리드의 변화를 보였고, 텍스트 리딩형은 많은 디자인 요소, 많은 양의 콘텐츠들이 한꺼번에 노출되고 변환이 되는 방식을 띄고 있어 다소 혼란스러운 구조를 보였다. 공통적으로 나타난 현상은 두 유형의 반응형 웹 매거진에서는 멀티미디어 요소가 제대로 활용되지 않았다는 점이다. 본 연구를 통해 실무에서 웹 매거진 디자인, 개발 설계 시 다양한 디바이스들의 특징을 파악하여 설계하는데 도움이 될 것이다. Increasing the growth of mobile Internet, the method of use in Web Services have evolved into the floating form which various smart devices use. Web design services to flexibly correspond to interfaces of new devices pouring into a market are being demanded. A Responsive Web production technique is necessary for the improvement of services and the efficiency of production in web magazines. And it is also required to the provision of identical user experiences and optimal services in each of various smart devices. In order to satisfy the above, We classify the type of web magazine into the visual reading type and the text reading type. And then focused on the Fashion·Current-affairs Magazines, we examine the design components and multimedia components, and compare the reactions of each sub-category. Visual reading type in web magazines presented a image-focused contents and a simple change of grids. And text reading type in web magazines have a complex structure of this method to expose and convert many design factors and contents at a time. The both types have something in common with which the multi-media factors have not been properly used by the Responsive Web Magazines of the two types. This study believes that the findings above help the working-level to figure out features of different devices and draw up designs when they try to create web magazines and make development plans.
