Abstract: Disclosed is a composition for alleviating symptoms of atopic dermatitis that contains a high molecular weight poly-gamma-glutamic acid and a low molecular weight poly-gamma-glutamic acid as active components. The composition for improving symptoms of atopic dermatitis inhibits epidermal and transepidermal water loss, improves desquamation (scaling skin), provides an excellent skin soothing effect, and relieves pruritus (itch) caused by dryness, thereby making remarkable improvement of general symptoms of atopic dermatitis.

Abstract: The present invention relates to nanomicelles composed of a complex of a lipophilic compound and a poly-gamma-glutamic acid wherein a portion of carboxyl groups are substituted with an amine group, and more particularly, to nanomicelles composed of a complex of a lipophilic compound and a poly-gamma-glutamic acid wherein a portion of carboxyl groups are substituted with an amine group, a preparation method thereof, and a drug delivery system employing the mucous membrane-adhesive property of the nanomicelles. According to the present invention, the nanomicelle drug delivery system based on poly-gamma-glutamic acid that is a natural biopolymer can be used for the delivery of a drug to mucous membranes to thereby increase the in vivo stability and effectiveness of the drug.

Abstract: The present invention relates to a hyaluronidase inhibitor containing poly-gamma-glutamic acid (PGA) as an active ingredient, a composition for maintaining skin elasticity and a composition for improving allergy, wherein each of the compositions contains PGA as an active ingredient. The inventive compositions containing PGA are effective in maintaining skin moisturization and skin elasticity by effectively inhibiting the activity of hyaluronidase which is an enzyme that degrades hyaluronic acid present in the skin dermis. Also, the compositions can relieve allergic symptoms by inhibiting the permeability of inflammatory cells.

Abstract: There is provided a substrate supporter capable of securely supporting a substrate such as a wafer on which a device having a predetermined thin film pattern is formed to remove various impurities formed on the rear surface of the substrate, and a plasma processing apparatus having the same. The plasma processing apparatus includes: at least one arm; and a supporting portion extending from the arm toward a substrate seating position of the substrate, so that the plasma processing apparatus can reduce the likelihood of arc discharges compared with conventional dry etching to increase process yield and product reliability, and ensure stable mounting of a substrate.

Abstract: The present invention provides a medical adhesive composition containing poly-gamma-glutamic acid or its salt; and sugar or sugar alcohol, which is edible, water-soluble, anionic and biodegradable. The invention also provides a thickener composition containing poly-gamma-glutamic acid, which can be used as a moisture-absorbing agent, a moisturizing agent and a raw material for cosmetic products.

Abstract: Provided are a plasma processing apparatus and method. The plasma processing apparatus includes a chamber, an upper electrode, a lower electrode, a substrate support, and a movement member. The upper electrode is disposed at an inner upper portion of the chamber. The lower electrode faces the upper electrode at an inner lower portion of the chamber to support a substrate such that a bevel of the substrate is exposed in a substrate level etching process. The substrate support is disposed between the upper electrode and the lower electrode to support the substrate such that a central region of a bottom surface of the substrate is exposed in a substrate backside etching process. The movement member is configured to move the substrate support to separate the substrate from the substrate support in the substrate backside etching process.

Abstract: Disclosed is an electromagnetic wave absorber, which is obtained by attaching a three-dimensional open-cell type metal porous body to an electromagnetic wave-reflecting surface and filling the pores of the three-dimensional open-cell type metal porous body with an electromagnetic wave-absorbing material.

Abstract: There is disclosed a cart for transportation, which includes a plurality of trays, a support for supporting the trays, a handle provided to the uppermost tray, and a wheel provided to the lowermost tray, which comprises a connecting pipe 112 attached to each corner of each of the trays 110, a supporting member 120 provided between upper and lower trays, a connecting member 130 for joining the supporting member 120 and the connecting pipe of the tray 110 with each other, a handle connecting member 140 for joining the handle 150 with the connecting pipe of the uppermost tray, and a wheel connecting member 160 for joining the wheel 170 with the connecting pipe of the lowermost tray. The invention can be assembled easily without using coupling devices and shipping charges can reduced as the volume of the components is minimized before the cart is assembled.
