Abstract: The present invention provides a method for manufacturing a wafer, comprising: a step of rinsing front and backside surfaces of the wafer, a step of securing hydrophobicity of the backside surface of the wafer; a step of improving particles distribution on the backside surface of the wafer, and a step of drying the front and backside surfaces of the wafer.

Abstract: The present disclosure relates to an auxiliary apparatus used to capture an image of teeth of a patient, and more particularly, to a support block that enables an image of teeth of the patient to be captured in a state where a natural dentition is maintained, and an imaging apparatus including the same. According to the dental support block of the present disclosure and the imaging apparatus including the same, imaging can be performed by reflecting a patient's normal occlusal state, thereby accurately checking and diagnosing a condition of teeth, dentition, and the like and treating accordingly.

Abstract: A method of controlling injection of a drug includes receiving a captured medical image of an object, identifying an object of interest from the medical image, based on a position and a shape of the object of interest, determining a drug injection position, based on the position and the shape of the object of interest, determining a plurality of electrode insertion positions, the plurality of electrodes being configured to supply a current to move the drug, defining a drug movement path based on a shape of the identified object of interest, generating current sequence information to move the drug along the drug movement path, the current sequence information defining a current applied over time to each of the plurality of electrodes, and outputting the current sequence information to a current source apparatus.

Abstract: An oral appliance allows the mandible to move forward, without putting strain on the temporomandibular joint and surrounding muscles, so that the oral appliance may be worn for a long time during sleep, thereby improving snoring. In addition, the oral appliance allows the tongue to move forward together with the mandible so that the tongue is naturally placed in the anterior region of the palate to induce conversion of mouth breathing to nasal breathing, thereby improving both snoring and sleep apnea.

Abstract: The present invention relates to an oral appliance, and more specifically, to an oral appliance enabling comfortable oral motor exercises while being effectively fastened to teeth by applying differing degrees of fastening to teeth to its incisor part and molar part. In the oral appliance and method for manufacturing the same according to the present invention, different degrees of fastening are applied to the incisor part and the molar part, thereby minimizing the user's inconvenience that arises when the user moves mouth while keeping the oral appliance stably fastened to the teeth.

Abstract: The present invention relates to an oral appliance, and more specifically, to an oral appliance that may remain fastened to the teeth for a long time by co-using a fastening portion and an assistant fastening portion on the molars. According to the present invention, the oral appliance co-uses a first fastening portion that provides a fastening by friction against the molars and a second fastening portion that provides a fastening by a fastening protrusion to remain fastened to the user's teeth although the frictional fastening force weakens over time. The second fastening portion may be configured of a circular protrusion, subjecting the oral appliance to a tiny movement even when worn, and increasing convenience.

Abstract: An oral appliance fixed to lower jaw teeth comprises a body having a shape corresponding to a teeth arrangement, a lower teeth recess formed in a lower portion of the body to allow lower jaw teeth to be inserted therein, an upper teeth recess formed in an upper portion of the body to allow upper jaw teeth to be inserted therein and allowing the lower jaw to move backward by a predetermined distance, and an upper teeth guide part formed to extend from the body to face a side of the upper jaw teeth. The lower teeth recess further comprises a lower molar fixing recess formed to strongly engage with at least a portion of left and right molars of the lower jaw teeth by frictional force, and a lower incisor recess formed to allow other lower jaw teeth except the left and right molars to position therein.

Abstract: Provided is a gastric cancer cell line derived from a mouse deficient in E-cadherin and p53, and a use thereof. The E-cadherin- and p53-deficient, murine-derived gastric cancer cell line of the present invention was confirmed to have histopathological characteristics similar to those of human gastric cancer, have an epithelial mesenchymal transition (EMT) phenotype and an activated ?-catenin pathway, and promote cancer growth in vivo due to potential of carcinogenesis, and thus the gastric cancer cell line of the present invention can be effectively used for the evaluation of the activity of new anticancer drugs and the development of metastasis inhibitors.
