In this study, we aimed to develop a fermented green rice beverage with a unique flavor and physiological function activity. With glutinous green rice and rice nuruk as independent variables, we modeled the antioxidant characteristics and α-glucosidase, α-amylase inhibitory activity of glutinous green rice fermented beverage to verify its significance. The total flavonoid content and α-glucosidase inhibitory activity were selected as Quadratic models, and DPPH radical scavenging ability and α-amylase inhibitory activity were selected as linear models. For the sensory characteristics of glutinous green rice fermented beverage, sweetness, sourness, savory taste, bitterness, throat feel, nuruk scent, and overall preference increased in preference as the amount of glutinous green rice and rice nuruk increased, but significantly decreased after the center point (p<0.01). A blending ratio of 180.00 g of glutinous green rice and 400.00 g of rice nuruk had the highest preference among all the sensory items. Based on these results, we developed a green rice fermented beverage with unique flavor and physiological function activity of rice using glutinous green rice and rice nuruk, and the optimal blending ratio was determined to be 164.04 g of white rice, 195.96 g of glutinous green rice, and 414.61 g of rice nuruk.

In this study, we aimed to study carnation italian ringspot virus (CIRV) in Erigeron annuus (L.) Pers. in Bonghwa County, Korea. The collected samples showed mosaic and malformation symptoms. To identify the virus species, we performed high-throughput sequencing, reverse transcription polymerase chain reaction, and cloning. The virus was confirmed to be an unreported species, and therefore we performed genome sequencing of the samples. The complete genome was 4,746 nucleotides in length. The CIRV contained five open reading frames (ORFs), and it showed the typical features of members of the genus Tombusvirus. Phylogenetic analyses revealed that ClRV isolates had the highest nucleotide identities with the CZ isolate (95.89%) from Korea. In recent years, these viruses have sporadically been reported in floral scent and medicinal plants. This research found the first natural host infected with CIRV, and provides baseline information to determine the correlation between weeds and crops.

This study focuses on the contents about the Urinalysis which is the most representative one of the Tibetan medicine. Also, this study compares it with the Urinalysis of Traditional Korean medicine. This study focuses on the simple history, the theoretical system, the diagnosis and the urinalysis mainly based on the documents related to the Tibetan medicine. Also, through the comparison with the contents of textbook of Traditional Korean Medicine and the urinalysis shown in the Dongeuibogam(東醫寶鑑) which is the representative Korean medical book, the difference between Tibetan Medicine and Traditional Korean Medicine will be observed. The contents related about the urinalysis of the Tibetan medicine are more specific than those of Traditional Korean Medicine. By observing the color, scent, vapor and sediment of one's urine together with periodic changes more thoroughly, it is possible to find out the cause of a certain disease. However, Traditional Korean Medicine examines the medical conditions mainly based on the state of discharge and fever, showing a clear difference. The Tibetan medicine has an extremely specific type of urinalysis in comparison with that of Traditional Korean Medicine. It is the only characteristic of the Tibet medicine, which cannot be found in any other traditional medicine. By applying the viewpoint of the doctor who diagnoses the patient by measuring his or her pulse, it is possible to make the diagnosing process more specific and accurate. It is expected that the follow-up study will be continuously executed with the introduction of the system for the urinalysis of the Tibetan medicine to Traditional Korean medicine.

Tricholoma matsutake is an ectomycorrhizal fungus, related with the host of Pinus densiflora. Most of studies on T. matsutake have focused on mycelial growth, genes and genomics, phylogenetics, symbiosis, and immune activity of this strain. T. matsutake is known for its unique fragrance in Eastern Asia. The most major component of its scent is (R)-(-)-1-octen-3-ol and is biosynthesized from the substrate linoleic acid by the sequential reaction of lipoxygenase and peroxide lyase. Here, we report for the first time the biosynthesis of (R)-(-)-1-octen-3-ol of T. matsutake using the yeast Saccharomyces cerevisiae as a host. In this study, cDNA genes correlated with these reactions were cloned from T. matsutake, and expression studies of theses genes were carried out in the yeast Saccharomyces cerevisiae. The product of these genes expression study was carried out with Western blotting. The biosynthesis of (R)-(-)-1-octen-3-ol of T. matsutake in recombinant Saccharomyces cerevisiae was subsequently identified with GC-MS chromatography analysis. The biosynthesis of (R)-(-)-1-octen-3-ol with S. cerevisiae represents a significant step forward.
