Abstract: A thermally stable polypeptide having FGF7 activity is provided. The polypeptide is a thermally stable polypeptide having FGF7 activity, wherein, in SEQ ID NO: 1, a 120th alanine (A) is substituted with cysteine (C), one including at least one substitution selected from substitution of a 126th lysine (K) with aspartic acid (D) and a 178th lysine (K) with glutamic acid (E) or aspartic acid (D) forms a salt bridge with a 175th arginine (R), and a 133rd cysteine (C) and a 137th cysteine (C) are disulfide bonded.

Abstract: A recombinant vector according to an embodiment of the present invention may produce fibroblast growth factor 19 (FGF19) having enhanced solubility. The synonymous codon substitution variant fibroblast growth factor 19 (scvhFGF19) and chaperone ?ssDsbC may be simultaneously and independently expressed in a host cell into which the recombinant vector is introduced, thereby it is possible to overexpress the fibroblast growth factor 19 in a soluble state.

Abstract: Disclosed is a mosquito attracting and killing apparatus with an air cleaning function. The mosquito attracting and killing apparatus attracts mosquitoes using a UV lamp and the mosquitoes are sucked into a collecting net by operation of a fan. The contiuous operation of the fan prevents the mosquitoes from escaping out of the collecting net and kills them. In addition, the mosquito attracting and killing apparatus employs a hopper having a tapered shape to easily clean the inside of the apparatus and efficiently reflect UV light emitted from the UV lamp.

Abstract: Disclosed is a mosquito repelling apparatus with an air filtering function. The mosquito repelling apparatus includes: a collecting container having an inlet, an outlet and a vacant space therein; an ultraviolet ray pylorus lamp installed at the inlet of the collecting container, for trepanning a mosquito; a collecting net installed at the outlet of collecting container; a fan installed within the collecting container such that the mosquito trepanned and killed by the ultraviolet ray pylorus lamp, is sucked into the collecting net during operation thereof; and an optical catalyst-coated layer coated on at least one surface of the collecting container. The mosquito can be killed only with the operation of the fan. The apparatus kills viruses having the mosquito as the mediator and drifting in the air, so that infection of person and domestic animal due to the viruses can be prevented.

Abstract: A water-saving toilet is disclosed. The water-saving toilet comprises: a toilet main body having an inlet orifice for introducing water from a water supply tube disposed at the outside of the main body, a toilet bowl for containing outside waste material and water supplied from the inlet orifice, and an outlet orifice for discharging the waster material and water in the toilet bowl; a discharge tube, one end of which is connected to the outlet orifice of the main body and the other end of which is connected to an outside outlet to serve as a discharge passage of waste material and water, including a curved portion which is movable up and down; means for moving the curved portion of the discharge tube up and down. With the water saving toilet, the waste material can be removed out of the toilet bowl with a minimum amount of water by the movement of the discharge tube. In addition, silent flushing operation is possible since open/close operation according to a siphon principle is not employed.

Abstract: A personal data communication apparatus that provides a camera, a magnified image in a display and a video telecommunication system within a compact handset housing is disclosed. The personal data communication apparatus can include a memory that stores image information from the camera converted into an electrical signal as data. A transmission controlling part accesses the data stored in the memory and transmits to a radio public telecommunication network in response to a user signal requesting a video communication and displays the image information received as an image signal from the public telecommunication network. The personal data communications apparatus can further include a receiver receiving a voice, a viewfinder type display adapted to magnify the image information, a speaker for transmitting a voice and a system driving part for entering system operation control signals by the user. The camera is a compact design using a diffractive optic system to be mounted within a housing.

Abstract: A plasma display panel includes a plurality of discharge cells formed with a plurality of partition walls arranged at fixed intervals between a front substrate and a rear substrate disposed in parallel spaced at a certain distance. A fluorescent material film is formed on a portion of an inside surface of each of the discharge cells. A discharge gas is sealed in each of the discharge cells and is converted into a plasma upon the occurrence of a discharge in each of the discharge cells. Each of the partition walls is formed with a stack of at least more than one permanent magnets magnetized with N and S poles for forming a magnetic field in the discharge cell.

Abstract: A reflection-preventing layer for a display device includes a transparent insulating substrate, at least one dielectric film formed on the transparent insulating substrate, and an amorphous carbon thin-film layer having a diamond-like carbon film on the uppermost dielectric layer of the dielectric films, so that the reflectance of the reflection-preventing layer is semi-permanently decreased while increasing the surface solidity thereof.

Abstract: An apparatus capable of performing an automatic tape ejection operation in an automobile-installed video cassette recorder comprises an input power detector for detecting an electrical disconnection between an automobile battery and the video cassette recorder when the automobile is turned off, a system controller, upon detecting the disconnection of the electrical power, for generating a switching control signal for a predetermined time period and a switch circuit, in response to the switching control signal, for electrically connecting the battery to a deck mechanism for the predetermined time period in which the tape ejection operation is executed.

Abstract: A reel table moving device for a video cassette tape recorder includes a mechanism for automatically positioning a pair of reel tables in response to insertion of a predetermined size video cassette without the need for an independent drive motor or sensor. The device includes a pair of protrusions mounted to opposite end portions of a moving member which are adapted to engage the tape cassette being inserted into the inlet port. The moving member moves in response to insertion of the tape cassette into the inlet port. In turn, an actuating member is connected to and moves in response to the movement of the moving member for causing the reel tables to move to a desired position for receiving a predetermined size tape cassette.
