Abstract: A method and apparatus for measuring a first bio-signal from a user in an unrestrictive manner are provided. The method includes extracting a second bio-signal including a motion signal and a respiration signal, based on the first bio-signal; determining an apnea measurement reference signal including a respiration measurement signal and a motion measurement signal, based on the second bio-signal; dividing the apnea measurement reference signal by a first time interval to generate a first evaluation signal, and dividing the first evaluation signal by a second time interval, that is smaller than the first time interval, to generate second evaluation signals; calculating standard deviation information based on the second evaluation signals; and determining a sleeping pattern for the second time intervals corresponding to the second evaluation signals, based on the standard deviation information.

Abstract: Provided is a natural dyeing method of a fiber using an indigo plant. The natural dyeing method includes dissolving a water-soluble pigment present in leaves of the indigo plant in water to mix the water containing the water-soluble pigment with lime powder and air, concentrating the resulting mixture into an insoluble pigment, mixing the concentrated indigo plant dye with caustic soda to reduce the resulting mixture into a water-soluble pigment through microbial fermentation, immersing a fiber in the soluble indigo plant dye solution to dye the fiber, and bringing the dyed fiber into contact with air to convert the soluble indigo plant dye solution into the insoluble pigment again, thereby completing natural dyeing using the indigo plant. Therefore, the natural dyeing can be performed at a very fast dyeing rate, and the fiber can show excellent color fastness. Also, the fiber cannot be easily discolored by water or detergent, and can be useful in preventing water pollution or dermatitis.
