Abstract: The present invention relates to a use of an agarobiose or agarooligosaccharides having anticariogenic activity. More specifically, a lower concentration of agarobiose or agarooligosaccharides than the concentration of xylitol suppresses the growth of Streptococcus mutans and suppresses acid production, and thus can be used for anti-cariogenic purposes.

Abstract: The present invention relates to a method for diagnosing the severity of rheumatoid arthritis using metabolite analysis. The present invention provides a biomarker which is for classifying the severity of rheumatoid arthritis in patients suffering from same through the analysis of joint capsule fluid metabolites, and can be applied to a kit for more specifically classifying the severity of rheumatoid arthritis in patients.

Abstract: The present invention relates to a method for metabolite sampling and analysis for reproducibly sampling as many metabolites as possible in a urine sample without changing to metabolites. The method has effects of presenting a biomarker detection method according to the sex or the like, by establishing optimal conditions for metabolite sampling in urine samples and presenting a metabolite comparison analysis method between different groups on the basis of the optimal conditions.

Abstract: A robot purifier including: a purifying part which draws, purifies, and discharges air; and a driving part which is located at a lower end of the purifying part and is capable of autonomous driving, wherein the purifying part is capable of rotating 360 degrees horizontally, and the purifying part also is capable of rotating vertically such that an air intake direction and an air discharge direction in the vertical and horizontal directions is controllable.

Abstract: The present invention relates to Nelumbo nucifera callus having an increased content of gallic acid or an extract thereof and to a method for preparing the same. The Nelumbo nucifera callus extract according to the present invention has an excellent whitening effect by containing a large amount of gallic acid, and thus can be advantageously used as a cosmetic composition.
