摘要:
An image reading apparatus capable of changing a main reading unit at an appropriate time point such that a plurality of reading units can be equally used, and a method of controlling the same. The image reading apparatus includes an automatic document feeder, a first reading unit to read a first side of a document fed by the automatic document feeder and to function as a main reading unit, a second reading unit to read a second side of the document fed by the automatic document feeder; and a control unit to change the main reading unit from the first reading unit to the second reading unit if the number of times La of usage of the first reading unit reaches a reference value. The control unit compares the number of times La of usage of the first reading unit with a predicted lifetime Lt of the first reading unit and changes the main reading unit to the second reading unit if it is determined that the number of times La of usage of the first reading unit reaches a predetermined percentage of the predicted lifetime of the first reading unit. The control unit determines whether the main reading unit is changed or not, based on frequencies of use of the first reading unit and the second reading unit.

Disclosed is a novel use of an immunoglobulin Fc fragment, and more particularly, a pharmaceutical composition comprising an immunoglobulin Fc fragment as a carrier. The pharmaceutical composition comprising an immunoglobulin Fc fragment as a carrier remarkably extends the serum half-life of a drug while maintaining the in vivo activity of the drug at relatively high levels. Also, when the drug is a polypeptide drug, the pharmaceutical composition has less risk of inducing immune responses compared to a fusion protein of the immunoglobulin Fc fragment and a target protein, and is thus useful for developing long-acting formulations of various polypeptide drugs.

The present invention provides a method for preparing a glass substrate with antireflection functionality by applying a coating formulation that affords antireflection effects to a substrate comprising water, metalloid oxide nano particles that are dispersed in said water, and a hydroxide ion agent or fluoride ion agent that is introduced into said metalloid oxide nano particles at a mole ratio of 0.005˜2:1. The coating formulation of the present invention enables manufacture of a porous nano antireflection film with high transmittance following a more streamlined process than the prior art, obtaining an antireflection film with a high adhesive force between the film and substrate, and high durability by increasing particle-particle bonding and the bond strength between particles and substrate.

Provided is a device for sampling and pretreating biological fluid. It comprises: a piercing unit having at a lower portion a capillary tip which is to be inserted into skin to a predetermined depth to take biological fluid therethrough; a dropper, connected to an upper portion of the piercing unit, having an injection tube at an upper portion thereof, the injection tube communicating with the capillary tip; and a reagent container, designed to accommodate the piercing unit therein in an airtight manner so as to seal an outer circumference of the piercing unit, functioning to contain a reagent for treating the biological fluid of the capillary tip of the piercing unit. The device allows even a novice to sample and pre treat biological fluid with high accuracy without the use of expensive precision devices. The device employs fewer expendable supplies, thus providing higher convenience for the user.
