Abstract: The present invention relates to: a novel Lactobacillus intestinalis YT2 strain (deposition number: KCCM11812P); and a composition for preventing, alleviating, or treating menopause, comprising, as an active ingredient, Lactobacillus intestinalis comprising the novel strain. The present inventors have established an animal model for menopause through ovariectomy, confirmed changes of the distribution of intestinal microorganisms by the model, identified and isolated a novel Lactobacillus intestinalis strain among lactic acid bacteria of which the distribution is significantly reduced in the menopausal model, and confirmed effects, by means of the novel strain and previously reported Lactobacillus intestinalis strains, of alleviating menopausal symptoms, such as the inhibition of an increase in body fat, the inhibition of a decrease in bone mineral density, the inhibition of an increase in the pain sensitivity, and the alleviation of depression.

Abstract: Provided is an apparatus for estimating blood pressure, including a pulse wave sensor configured to measure a pulse wave signal of a user, and a processor configured to obtain, based on the pulse wave signal, one or more feature values corresponding to the blood pressure, detect whether a change in a posture of a user from a first posture to a second posture occurs while measuring the pulse wave signal, based on the change in the posture being detected, correct a reference blood pressure based on a blood pressure variation caused by the change in the posture, correct the one or more feature values based on a variation in one or more pulse wave signal feature values caused by the change in the posture, and estimate the blood pressure based on the corrected reference blood pressure and the corrected one or more feature values.

Abstract: An apparatus for estimating blood pressure may include: a photoplethysmogram (PPG) sensor configured to measure a PPG signal from a user; and a processor configured to: extract a cardiovascular feature from the PPG signal; calculate a first variation in the extracted cardiovascular feature compared to a reference cardiovascular feature measured at a reference time; determine a measurement posture of the PPG signal based on a time interval between two waveform components of the PPG signal; in response to the measurement posture corresponding to the reference posture, estimate the blood pressure based on the first variation; and in response to the measurement posture not corresponding to the reference posture, obtain a second variation by correcting the first variation; and estimate blood pressure based on the second variation.

Abstract: An apparatus for non-invasively estimating bio-information and a method of determining whether a bio-signal is normal by the apparatus for estimating bio-information are provided. The apparatus for estimating bio-information according to an embodiment of the disclosure includes: a photoplethysmogram (PPG) sensor configured to measure a PPG signal from an object; and a processor configured to extract a plurality of pairs of local maximum points and local minimum points from a second derivative signal of the PPG signal, to select at least one reference pair from among the extracted plurality of pairs, and to determine whether the PPG signal is normal based on the selected at least one reference pair.

Abstract: Provided is a method of preparing fermented milk containing Lactobacillus plantarum SFB1 (KCCM11237P). Owing to rapid production of lactic acid and curd, the fermented milk can significantly reduce fermentation time, maintain high lactic acid bacteria numbers, reduce manufacturing costs, improve production efficiency and provide excellent sensory characteristics.

Abstract: The present invention relates to an anti-hacking system through telephone authentication, in which authentication is performed over a communication network in order to guarantee safer integrity authentication in implementing an authentication system configured to issue various documents to only an authenticated user through electronic financial transactions, such as Internet banking, or verification or accessible to only the authenticated user. The anti-hacking system through telephone authentication includes an access terminal connected to an Internet and configured to access a site requiring user authentication, a communication terminal owned by a user of the access terminal, a main server configured to access the communication terminal, perform telephone authentication by checking authenticity of the user, and process the user authentication.

Abstract: A probe card of a semiconductor test apparatus includes a printed circuit board (PCB) in which a signal wiring and a first ground plate are provided, a needle fixture mounted at the PCB and provided to fix a plurality of needles, a second ground plate provided at the needle fixture, a plurality of signal lines connecting the signal wiring to the plurality of needles corresponding to the signal wiring, a plurality of ground lines connecting the first ground plate to the second ground plate and corresponding to the plurality of signal lines, and a connecting electrode connecting the first ground plate to the second ground plate. A method of fabricating the same is also provided.

Abstract: The socket assembly includes a guide block, a guide part and a pressurizing plate. The guide block is in a terminal region of a test board, the guide block defining an area into which an integrated circuit can be inserted opposite terminals formed on the test board in the terminal region. The guide part is provided on an inner side wall of the guide block, to guide an insertion position of the integrated circuit so that respective leads of the integrated circuit are aligned with the corresponding terminals of the test board. The pressurizing plate is adapted to interface with the guide block, the pressurizing plate including a pressurizing protrusion on a surface thereof, such that when the pressurizing plate is applied to the guide block, the respective leads of the integrated circuit are urged to connect with the corresponding terminals of the test board.
