A bundle tube type optical cable comprises: a bundle of optical fiber tubes being arranged in the middle portion of the optical cable and each containing at least two optical fiber cores loosely arranged therein; a first water-blocking layer protecting the optical fiber cores in the optical fiber tube from external moisture by a water-blocking material filled in the inner space of the tube; an inner shell made of aluminum material enclosing the bundle of optical fiber tubes with a predetermined gap; a second water-blocking layer protecting the optical fiber tubes from external moisture by the water-blocking material filled in the inner space of the inner shell; and an outer sheath made of plastic material enclosing the outer surface of the inner shell.

Abstract: The present invention relates to an adjuvant and vaccine composition containing pre-S of the hepatitis B virus, and more specifically to a modified recombinant pre-S that can enhance immunogenicity of a general vaccine antigen. The present invention also relates to an improved prophylactic Hepatitis B virus (HBV) vaccine and a therapeutic vaccine for the treatment of chronic HBV carriers.

Abstract: A method and apparatus for enhancing a transfer efficiency of electronic photograph development equipment, which enhances the transfer efficiency by controlling a transfer voltage output from a transfer voltage output end by a pulse width modulation command under the control of a microcomputer based on a transfer environment and a paper sheet recognition of the electronic photograph development equipment.

Abstract: An image forming device, including a charging unit to electrically charge a surface of an organic photoconductive medium; a light exposure unit to form an electrostatic latent image on the surface of the organic photoconductive medium; a developing unit to develop the electrostatic latent image formed with a developer; a transfer roller to transfer an image developed by the developing unit to a recording paper; a light array having a plurality of light sources arranged in a predetermined pattern; a first light path providing unit to form a light path to receive a first light portion emitted from the light sources and to allow the light to be projected on the organic photoconductive medium between the developing unit and the transfer roller; and a second light path providing unit to form a light path to receive a second portion of the light emitted from the light sources and to allow the light to be projected onto the organic photoconductive medium passing through the transfer roller, thereby removing an elect

Abstract: A method for fabricating a printed circuit board includes the steps of: fabricating a printed circuit board having at least one collapsed portion; depositing a first solder resist in the collapsed portion; exposing the first solder resist-coated printed circuit board at a pressure lower than atmospheric pressure for a predetermined time; coating a second solder resist on the entire surface of the printed circuit board; and drying and hardening the first and the second solder resists. With this method, when a solder resist is coated, since an air space does not remain in a blind via hole, the reliability of the attachment between a printed circuit board and the solder resist layer is increased.

Abstract: A chemical mechanical polishing (hereinafter, referred to as ‘CMP’) slurry for metal is disclosed, more specifically, method for manufacturing metal line contact plug of semiconductor device using an acidic CMP slurry for oxide film further comprising an oxidizer and a complexing agent, which polishes a metal, an oxide film and a nitride film at a similar speed, thereby easily separates a metal line contact plug.

Abstract: The invention is aimed at discovering a new type of anti-cancer compound which can exert an excellent inhibitory activity against the heparanase. A fungal strain Acremonium sp. MT70646 (KCTC 8973P) was isolated from the soil. From the culture of the isolated fungal strain, novel compounds that can inhibit both heparinase and heparanase was purified. Therefore, the present invention regards to provide a newly isolated fungal strain Acremonium sp. MT70646 (KCTC 8973P), its new products, and pharmaceutical agents such as a heparinase inhibitor, a heparanase inhibitor, a metastasis inhibitor and an angeiogenesis inhibitor all of which contain the above new compounds produced by the fungal strain as an active ingredient.

Abstract: A resource allocation request method in a wireless system, including base stations and terminals, includes the steps of: periodically broadcasting resource information, managed by the base stations, to the terminals; receiving and storing the periodically-broadcast resource information in the terminals; making a determination, in response to a resource allocation request, by comparing the parameter value of a resource, extracted from the stored resource information, with a preset critical value when a terminal receives an application command corresponding to the resource allocation request from a user; and, variably requesting resource allocation of the base stations according to the determinations by the terminals in response to the resource allocation requests.

Abstract: A device for carrying artillery shells, each shell having a cylindrical body and a conical head, is disclosed. The device includes an upper body and a lower body. A gripper assembly is connected to the lower body and has an inner circumferential surface corresponding to the cylindrical body. A driving unit pivots the gripper assembly about an axis. A shell-head stopping unit is connected to the lower body at a position which may be adjusted along the length of the lower body. The shell-head stopping unit receives the conical head of a shell to hold the shell in a set position. Also included is a shell-rear stopping unit connected to the gripper assembly and elastically biased upward with respect to the inner circumferential surface of the gripper assembly. The shell-rear stopping unit holds the rear end of the shell in the gripper assembly.
