    Abstract: The present invention relates to a pulse depth index extraction device and method using pressure at a constant velocity. A device comprises: a pressure applying unit for applying a pressure at a constant velocity to a confirmed pulse location in a direction perpendicular to the skin; a pressure pulse wave signal measuring unit for measuring a pressure pulse wave signal generated based on the applied pressure; and a measured signal analysis unit for deriving the pulse depth index (PDI) by using the measured pressure pulse wave signal.

    Abstract: A method for determining a sharpness index of a pulse wave signal includes receiving a pulse wave signal; determining a first reference line starting point and a second reference line starting point on the basis of a curvature of the pulse wave signal; determining a first reference line connecting the first reference line starting point and a first reference line ending point by determining the first reference line ending point by applying an intersecting tangent method to the first reference line starting point, and determining a second reference line connecting the second reference line starting point and a second reference line ending point by determining the second reference line ending point by applying the intersecting tangent method to the second reference line starting point; and determining a sharpness index by using a peak point of the pulse wave signal, the first reference line, and the second reference line.

    Abstract: A method for treating a sleep disorder according to an embodiment of the present disclosure includes administering a composition comprising an extract of Hibiscus syriacus as an effective ingredient to a subject in need thereof. Because the Hibiscus syriacus extract of the present invention has an effect of improving sleep time deteriorated by stress, and an effect of reducing the content of corticosterone, which increases due to stress, and increasing the content of serotonin in blood. In addition, the composition has an effect of enhancing in a significant sense the expression of GABAR A α1 in cerebral cortex, which decreases due to stress, in a group administered with Hibiscus syriacus extract. As such, the composition comprising Hibiscus syriacus extract as an effective ingredient as an effective ingredient can be advantageously used as a functional health food composition or a pharmaceutical composition for preventing, ameliorating or treating sleeping disorders.
