Provided are a plastic microfluid control device having a multi-step microchannel and a method of manufacturing the same. The device includes a lower substrate, and a fluid channel substrate contacting the lower substrate and having a multi-step microchannel having at least two depths in a side coupling to the lower substrate. Thus, the device can precisely control the fluid flow by controlling capillary force in a depth direction of the channel by controlling the fluid using the multi-step microchannel having various channel depths. A multi-step micropattern is formed by repeating photolithography and transferred, thereby easily forming the multi-step microchannel having an even surface and a precisely controlled height.

The method includes: obtaining an ultrasonic image of area of an organ of a living body; determining a target area in the ultrasonic image of area; obtaining a quantified representative coarseness level of the target area from a brightness level distribution of pixels in the target area; and calculating a coarseness level of the organ of a living body, corresponding to the quantified representative coarseness level.
摘要:
The present invention relates to a method for dynamically allocating bandwidth under a media access control (MAC) protocol between an optical line termination (OLT) and a group including a plurality of optical network units (ONUs) in an ATM-PON. In order to meet quality of service (QoS) requirement, the dynamic bandwidth allocation method is capable of determining bandwidth to be allocated to each of the ONUs on the basis of information about traffic indicators of connections established to each of the ONUs and about the number of non-real time cells waiting in each of the ONUs, resulting in an enhancement in utilization efficiency of an upstream transmission channel and enabling an effective transmission.
