  • Publication number: 20250095971
    Abstract: A plasma processing apparatus includes: a plasma chamber; a radio frequency (RF) power supply configured to generate plasma in the plasma chamber; an electromagnet configure to apply a magnetic field to the plasma; and a pulse current generator configured to provide a pulse current to the electromagnet, wherein each period of the pulse current includes a first section and a second section subsequent to the first section, and the pulse current generator is further configured to: provide, at the first section, the pulse current to the electromagnet in a first direction to generate the magnetic field, and provide, at the second section, the pulse current to the electromagnet in a second direction opposite to the first direction to reduce intensity of the magnetic field generated at the first section.

  • Publication number: 20240307529
    Abstract: The present invention relates to a composition for immunotherapy of allergic diseases, comprising house dust mite antigens and hyaluronic acid hydrogels as active ingredients. By using hyaluronic acid as a material, and forming a crosslinking with the house dust mite antigens via a photoinitiator and visible light, it can overcome the disadvantage of easy degradation and simultaneously exploit biocompatible features. Moreover, it can provide a large amount of antigens to immune cells with a single administration, and despite this, it does not induce foreign body reactions, drug reactions, or immune responses, while generating excellent immune tolerance effects. Its safety is outstanding and it does not require repeated injections over a long period. Thus, it is expected to be useful as a preventive or therapeutic agent for allergic diseases induced by house dust mites.

  • Publication number: 20220233069
    Abstract: An apparatus for assisting an eyelid examination according to an embodiment of the present disclosure assists eversion of an eyelid in order to observe conjunctiva or meibomian glands of the eyelid. The apparatus may include a clamping part configured to hold eyelid or eyelashes around the eyelid, a pressing part having one side connected to the clamping part and the other side in contact with an upper boundary portion of an upper eyelid plate formed along an eyeball line of the eyelid, and a handle part having one side connected to the clamping part and the other side extending while having an angle with the clamping part so that a force for the eyelid eversion is applied to the clamping part at a location spaced apart from the eyelid.
