A method of preparing a heparin-conjugated fibrin gel is provided, which includes activating heparin, conjugating the activated heparin with fibrinogen to prepare heparin-conjugated fibrinogen, mixing free fibrinogen with the heparin-conjugated fibrinogen to prepare a fibrinogen mixture, and mixing thrombin with the fibrinogen mixture. In addition, a heparin-conjugated fibrin gel prepared by the above method and a kit for preparing the same are provided. According to the method of preparing the heparin-conjugated fibrin gel, the heparin-conjugated fibrin gel having an affinity for drugs such as growth factors may be easily prepared at low costs, and can also be used as a therapeutic drug excellently effective on generation of tissues such as bones, skin, blood vessels, cartilages, etc. by sustainably releasing drugs such as growth factors to a local site for a long period of time through injection into a human body.

The present invention relates to an implant which is surgically inserted in vivo such as an artificial knee joint or artificial hip joint. More particularly, the present invention relates to an implant for in-vivo insertion, wherein the porosity of a porous coating layer formed on the surface of the implant, thus increasing the bone adhesion of the implant into pores, the adhesivity between the implant and the porous coating layer and the adhesivity between particles in the porous coating layer, wherein vertically-curved pores each having a radius of 100˜300 μm are formed in the porous coating layer to increase the adhesivity of the implant to the bone growing into the pores, thus increasing bone adhesion, and wherein the ratio of interconnected pores in the porous coating layer is increased, and thus bones growing into the pores are interconnected, thereby increasing the adhesivity between the implant and the bones.

Disclosed is an exhaust reflux type cleaning robot. In the cleaning robot, foreign substances along with air are sucked into a suction unit by a suction motor, and the foreign substances are collected in a dust collecting unit while the air from which the foreign substances have been removed is discharged to the outside via the suction motor. The cleaning robot includes an exhaust reflux unit which has the suction motor and is provided with left and right air passages disposed on opposite sides of the suction motor, a discharge nozzle unit which is connected to the left and right air passages, a suction unit which is configured such that the discharge nozzle unit is disposed in front of the suction unit, and a sterilization anion generating unit which generates sterilization anions to sterilize air discharged via the suction motor.

Provided are a variety of snap cure apparatus configuration and corresponding methods for operating each such apparatus in order to snap cure an adhesive composition. Each of the configurations includes at least one vertical stack of heater blocks whereby the horizontal area required for conducting the snap cure processing may be reduced. Depending on the configuration utilized, two or more transfer devices may be required to remove the substrate(s) from a conveyor, index the substrate(s) through the heater blocks to apply the predetermined thermal cycle and return the cured substrate to the conveyor. Similarly, depending on the particular adhesive utilized, the number, relative temperatures, and duration of the substrate(s) on each of the heater blocks may be adjusted to provide the desired degree of curing.

The present invention is a new composite bone graft material made from biocompatible poly(D,L-lactic-co-glycolic acid) (PLGA) and nano-sized hydroxyapatite particles exposed on its surface using a gas foaming particle leaching (GF/PL) method. A further embodiment of this invention involves coating this PLGA/hydroxyapatite biomaterial with an adherent, fast, uniform coating of a mineral such as apatite. The PLGA polymer portion of the composite provides sufficient mechanical strength to replace bone and is degradable over time to allow new bone tissue ingrowth. The incorporated hydroxyapatite particles increase the composite material's osteogenic properties by providing sites for tissue attachment and propagation. Finally, a uniform coating of mineral apatite on the surface of this novel biomaterial composite further enhances its osteogenic qualities.

Disclosed is an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, including a suction motor to intake not only air but also dust from a to-be-cleaned surface through a suction unit installed at the bottom surface and a dust collector to trap dust so as to allow dust-free air to be discharged via the suction motor. In the robot cleaner, the disinfectant anion generator emits disinfectant anions to disinfect the air having been discharged via the suction motor, a spray nozzle installed at the front end of an intake port of the robot cleaner sprays the disinfected air toward the cleaning surface through an exhaust air feedback unit so that the dust on the to-be-cleaned surface may be scattered and disinfected, and finally the air, together with the dust, is sucked in by the suction motor and circulated again to the exhaust air feedback unit.

A cleaning robot having an exhaust air feedback function can utilize the vacuum suction force generated by a suction motor as well as spray exhaust air onto the surface to be cleaned by circulating the air using the suction motor, thereby improving foreign material removal efficiency. The cleaning robot includes a suction unit, a suction motor for drawing in foreign materials from the surface to be cleaned, along with air, through the suction unit, a dust collector for capturing the foreign materials, so that the air is exhausted through the suction motor, and an exhaust air feedback unit for feeding the air. The cleaning robot also includes a spray nozzle unit inserted into the suction unit and placed on the leading end of the suction unit, the spray nozzle unit spraying the air fed by the exhaust air feedback unit, to the surface to be cleaned.

Disclosed herein is a light source device. The light source device includes a front transparent substrate, a rear substrate, a plurality of partitions, and fluorescent material. The rear substrate is configured to face the front transparent substrate with a discharge space disposed therebetween. The partitions are arranged between the front transparent substrate and the rear substrate to divide the discharge space into a plurality of discharge channels. The fluorescent material is applied on the inside of the discharge space. Meanwhile, the partitions are formed such that the ratio of the radius of curvature R of each partition to the width W of the partition, that is, R/W, ranges from 0.1 to 4.
