Disclosed are a method and system for evaluating current spreading of a light emitting device. The method includes applying current to a light emitting device and acquiring a luminescence image corresponding to a digital signal, converting the luminescence image into a gray image, and determining the number of pixels having gray levels greater than a set threshold among pixels included in the luminescence image converted into the gray image, as a criterion for determining the degree of current spreading of the light emitting device.The luminescent area of the light emitting device is quantified as an objective value on the two-dimensional plane by using an image processing technique, so that the degree of current spreading in the light emitting device can be evaluated.

摘要:
A detergent container of a washing machine in accordance with the present invention comprises a powdered detergent chamber to store powdered detergent, an outlet to discharge powdered detergent mixed with water in the powdered detergent chamber, a subsidiary detergent chamber to store bleach or fabric softner, a drain passage to guide powdered detergent mixed with water from the powdered detergent chamber to the outlet, and a bypass passage to allow powdered detergent mixed with water to bypass from the powdered detergent chamber to the drain passage. Even though an excessive volume of powdered detergent is placed in the powdered detergent chamber and the drain passage is clogged, powdered detergent mixed with water can be drained from the detergent container through the bypass passage, thus powdered detergent can be supplied to a tub of the washing machine without a hitch.

The present invention relates to a method for inhibiting angiogenesis using a peroxiredoxin II (Prx II) inhibitor, and a method for preparing angiogenesis-inhibiting medicines using Prx II inhibitor. According to the present invention, the inhibitor of Prx II gene expression or Prx II protein activity increases oxidative inactivation of VEGF receptor tyrosine kinase (RTK) to reduce VEGF signaling, thereby screening a novel angiogenesis inhibitor. Therefore, the method of the present invention can be used for the prevention or treatment of various diseases, ailments, and conditions related to angiogenesis.
