Abstract: A joint apparatus for prevention of explosion includes a bellows tube including an extension section integrally formed at one end of the bellows tube and an annular protrusion interposed between the extension section and the bellows tube; a coupling nut coupled with the bellows tube; and a connection member coupled with the bellows tube while being supported by the annular protrusion. A gap is formed between a the extension section and the connection member and gas discharged from the bellows tube flows along the outer surface of the extension section through the gap and is discharged to an outside through a rear section of the annular protrusion. Since a travelling path of the gas is lengthened, pressure and temperature of the gas are lowered, so that gas explosion is prevented.

Abstract: A connector is used to connect pipes for conveying a fluid. A plastic male screw connector is manufactured through injection molding of a plastic material to replace a conventional screw connector made of a costly metallic material so that the manufacturing costs can be reduced. Since the screw connector is manufactured through injection molding, mass production of the screw connector becomes possible and the manufacturing costs can be significantly reduced. Also, the plastic material of the screw connector allows for the connector to handle high pressure, resist corrosion and reduce fluid friction.

Abstract: An embodiment of the present invention relates to a connector used to connect pipes for conveying a fluid, and more particularly, to a plastic female screw connector which is manufactured through injection molding to replace a conventional screw connector made of a costly metallic material with an injecting-molded plastic screw connector so that the manufacturing costs can be reduced. According to the plastic female screw connector manufactured through injection molding according to the embodiment of the present invention provides advantages in that, since a screw connector for connecting pipes is manufactured through injection molding of a plastic material, mass production of the screw connector becomes possible and the manufacturing costs can be significantly reduced. Also, because the screw connector is made of the plastic material, excellent pressure resistance with respect to a high pressure, corrosion resistance with respect to a fluid used, and friction resistance can be accomplished.

Abstract: Disclosed is a flexible hose assembly with a joint. The flexible hose assembly includes a bellows tube including an extension section integrally formed at one end of the bellows tube and an annular protrusion interposed between the extension section and the bellows tube; a coupling nut coupled with the bellows tube; and a connection member coupled with the bellows tube while being supported by the annular protrusion. A gap is formed between a the extension section and the connection member and gas discharged from the bellows tube flows along the outer surface of the extension section through the gap and is discharged to an outside through a screw coupling section between the connection member and the coupling nut. Since a travelling path of the gas is lengthened, pressure and temperature of the gas are lowered, so that gas explosion is prevented.

Abstract: A communication method and apparatus of a dual standby mode mobile terminal for improving the emission performance are provided. The mobile terminal includes a master switch for connecting a master antenna to a master Radio Frequency (RF) unit for communication with a first network, a slave switch for connecting a slave antenna to a slave RF unit for communication with a second network, a slave control unit for controlling communication with the second network and for detecting attachment of a slave Subscriber Identity Module (SIM), and a master control unit for controlling communication with the first network, for detecting attachment of a master SIM, and for controlling the master and slave switches to establish/release either the connection between the master antenna and the master RF unit or the connection between the slave antenna and the slave RF unit.

Abstract: Systems and methods for detecting vulnerability of a server are provided. One system includes: a check server for collecting response information with respect to at least one predetermined command from one or more service servers that provide service, and thus may be attacked from outside, and detecting and analyzing vulnerabilities of the service servers based on the collected response information; an administration terminal for displaying the results of detecting and analyzing the vulnerabilities of the service servers; and a database for storing and managing pattern information concerning the detected vulnerabilities. One method includes identifying a server that may be attacked by port scanning, receiving response information with respect to at least one predetermined command from the identified server, detecting and analyzing vulnerability of the server based on the response information, and reporting the result of the detection to an administration terminal.

Abstract: Systems and methods for detecting false code in web pages linked to a web site are provided. One system includes a web server for administering the web site and a surveillance server for collecting generated or updated web pages from among the web pages linked to the web site, selecting tags of a given tag type included in the collected web pages, determining whether the selected tags comprise false code, and providing the determination result to an administrator terminal such that an administrator can check the determination result. One method includes collecting web pages that were generated or updated within a set time period from among the web pages linked to the web site, determining whether tags included in the collected web pages comprise false code, and providing the determination result to an administrator terminal such that an administrator can check the determination result.

Abstract: A shoe with springs is disclosed. The shoe includes a sole, two or more fixing plates fixed to the sole, a supporting plate in contact with ground, two or more coil springs mounted between the sole and the supporting plate, and a cover formed in a bellows shape to be folded and unfolded according to contraction and expansion of the coil springs. The cover includes coupling protrusions at an upper end and a lower end. The sole and the supporting plate are formed with coupling grooves along side surfaces, in which the coupling protrusions of the cover are fitted. The coil springs are configured such that a diameter is gradually increased from an upper end portion to a lower end portion. Therefore, the coil springs are shielded by the cover and a coupling structure of the coil springs is improved to prohibit bending of the coil springs in a lateral direction, thereby increasing safety and protecting a user or a bystander from physical damage or injury.
