Abstract: An apparatus for estimating blood pressure is provided. According to one embodiment, the apparatus for estimating blood pressure may include: a first sensor configured to obtain a pulse wave signal of a green wavelength from an object when the object is in contact with the first sensor; a second sensor configured to measure an external force applied to the second sensor while the first sensor is obtaining the pulse wave signal; and a processor configured to obtain an oscillometric envelope based on a direct current (DC) component of the pulse wave signal of the green wavelength and the external force, and estimate the blood pressure using the oscillometric envelope.

Abstract: The present application relates to a composition for manufacturing paper and a method for manufacturing paper using same. The composition for manufacturing paper of the present application comprises a pulp fiber and a polymer fiber, and the content ratio between the pulp fiber and the polymer fiber is 50:50 to 95:5.

Abstract: Provided are a method of preparing a spheroid of stem cells and a composition including the spheroid prepared by the method, the method including: culturing stem cells in a medium supplemented with matrilin-3 protein; and performing 3D cell culture on the cultured stem cells in the medium. The composition disclosed herein has effects of preventing or treating cartilage disease. In detail, the composition may be able to further promote cartilage differentiation of adult stem cells and reduce dedifferentiation and hypertrophy that may occur during cartilage regeneration, thereby providing a more effective cartilage tissue regeneration method.

Abstract: The present invention relates to an electronic device, and to an electronic device and a method for providing service information.
