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.

Due to the COVID-19 pandemic, the size of the e-commerce has been increased rapidly. This pandemic, which made contact-less communication culture in everyday life made the e-commerce market to be opened even to the consumers who would hesitate to purchase and pay by electronic device without any personal contacts and seeing or touching the real products. Consumers who have experienced the easy access and convenience of the online purchase would continue to take those advantages even after the pandemic. During this time of transformation, however, the size of information source for the consumers has become even shrunk into a flat screen and limited to visual only. To provide differentiated and competitive information on products, companies are adopting AR/VR and steaming technologies but the reviews from the honest users need to be recognized as important in that it is regarded as strong as the well refined product information provided by marketing professionals of the company and companies may obtain useful insight for product development, marketing and sales strategies. Then from the consumer's point of view, if the ratings of reviews are widely diverged how consumers would process the review information before purchase? Are non-converged ratings always unreliable and worthless? In this study, we analyzed how consumer's regulatory focus moderate the attitude to process the diverged information. This experiment was designed as a 2x2 factorial study to see how the variance of product review ratings (high vs. low) for cosmetics affects product attitudes by the consumers' regulatory focus (prevention focus vs. improvement focus). As a result of the study, it was found that prevention-focused consumers showed high product attitude when the review variance was low, whereas promotion-focused consumers showed high product attitude when the review variance was high. With such a study, this thesis can explain that even if a product with exactly the same average rating, the converged or diverged review can be interpreted differently by customer's regulatory focus. This paper has a theoretical contribution to elucidate the mechanism of consumer's information process when the information is not converged. In practice, as reviews and sales records of each product are accumulated, as an one of applied knowledge management types with big data, companies may develop and provide even reinforced customer experience by providing personalized and optimized products and review information.

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.

RFID has been used as an identification tool that substitutes for bar codes. Its areas of application are increasing due to its suitability in ubiquitous environment. In this paper, first, we review various aspects of RFID, including standards, characteristics, and relationships with wireless sensor networks. Then, we review the technical aspects of RFID and its areas of application, e.g., supply chain management (SCM) and manufacturing since 2005. SCM, in which RFIDs can shorten lead time and ensure the quality of products, is one of the most active application areas. Manufacturing is a relatively new area for RFID applications, but it is believed that it can enhance the productivity and the reliability of the products. Also, the authors suggest research issues and limitations of RFID, as well as possible application areas related to marine engineering.

The fragrance has a great influence on consumers' cognition, emotional response, attitude, memory, and behavior since the human sense of fragrance is physically and neurologically closer to the hippocampus of the brain. The fragrance materials are exposed to humans ranging from skin interaction to inhalation. We have lots of stories and literature on the usage of fragrance in everyday life in Korea from the Dangun myth to present K-beauty cosmetics. In Korean history, such archives as Dong-Eui-Bo-Gam and Gyu-Gak-Chong-Seo at Joseon Dynasty clearly recorded the application of many weeds for the manufacture of various fragrance products. In recent times, fragrances in weeds have been being applied to touch the consumer's feelings. The present mini-review is an attempt to introduce and discuss fragrant weeds in the archives and in science journals, effects of fragrant weeds on the human electroencephalographic activity, and effects of fragrance on the behavior of consumers. This review could be useful for the development of natural cosmetic and perfumery products from fragrant weeds.

Background: In Korea, a healthy 36-year-old man developed acute interstitial pneumonitis soon after inhaling a waterproofing spray which he had applied at home to his outdoor jacket. Objectives: The objectives of this study were to review cases of varying degrees of respiratory toxicity and poisoning in connection with the use of waterproofing spray and summarize major reasons for cases of poisoning. Methods: We searched articles reporting on a combination of a waterproofing agent and/or respiratory symptoms, including acute respiratory syndrome, lung injury, pneumonia, pulmonary toxicity, and respiratory disease. Results: We reviewed a number of cases of varying degrees of respiratory toxicity and poisoning resulting from inhalation of waterproofing spray containing fluorocarbon co-polymer, solvents and propellants reported in a variety of countries. The literature searches concluded that among the ingredients of waterproofing agents, fluorinated polymer may cause acute respiratory health effects. Conclusion: Environmental policy should be implemented in order to prevent consumers from using household and industrial products including waterproofing agents. In addition, a national surveillance system should be created to collect cases of poisoning caused by the use of consumer products.

Bovine mastitis, an inflammation of the mammary gland, is the most common disease of dairy cattle causing economic losses due to reduced yield and poor quality of milk. The etiological agents include a variety of gram-positive and gram-negative bacteria, and can be either contagious (e.g., Staphylococcus aureus, Streptococcus agalactiae, Mycoplasma spp.) or environmental (e.g., Escherichia coli, Enterococcus spp., coagulase-negative Staphylococcus, Streptococcus uberis). Improving sanitation such as enhanced milking hygiene, implementation of post-milking teat disinfection, maintenance of milking machines are general measures to prevent new cases of mastitis, but treatment of active mastitis infection is dependant mainly on antibiotics. However, the extensive use of antibiotics increased concerns about emergence of antibiotic-resistant pathogens and that led the dairy industries to reduce the use of antibiotics. Therefore, alternative therapies for prevention and treatment of bovine mastitis, particularly natural products from plants and animals, have been sought. This review provides an overview of bovine mastitis in the aspects of risk factors, control and treatments, and emerging therapeutic alternatives in the control of bovine mastitis.

Background: Frequent outbreaks of foodborne illness have been increased awareness of food safety. CDC estimates that each year roughly 48 million people gets sick, 128,000 are hospitalized and 3,000 die of foodborne diseases in US. In Korea, 6,058 were hospitalized and 266 incidents were reported in 2012. It is required to develop rapid methods to identify hazard substances in food products for protecting and maintaining safety of the public health. However, conventional methods for pathogens detection and identification involve prolonged multiple enrichment steps. Purpose: This review aims to provide information on biosensors to detect pathogens in food products to enhance food safety. Results: Foodborne outbreaks continue to occur and outbreaks from various food sources have increased the need for simple, rapid, and sensitive methods to detect foodborne pathogens. Conventional methods for foodborne pathogens detection require tremendous amount of labor and time. Biosensors have drawn attentions in recent years because of their ability to detect analytes sensitively and rapidly. Principles along with their advantages and disadvantages of a variety of food safety biosensors including fiber optic biosensor, impedimetric biosensor, surface Plasmon resonance biosensor, and nano biosensor were explained. Also, future trends for the food safety biosensors were discussed.
