Abstract: The present invention relates to a portable pipe outer diameter-chamfering apparatus with improved weldability characterized in that a vertical fixing plate is fixed to the outside of the vertical plate, a horizontal fixing plate is fixed in an orthogonal direction to the tip of the vertical fixing plate, a ? shaped link is coupled to move upward and downward along the vertical fixing plate, a circumscribing roller which is in close contact with an outside of a pipe are installed on the tip of the ? shaped link on either side, the ? shaped link moves up and down along the vertical fixing plate by a circumscribing roller adjustment screw installed on the horizontal fixing plate, a moving body is installed in the horizontal fixing plate, the moving body moves up and down by an inscribing roller adjustment screw installed on the horizontal fixing plate, and an inscribing roller which is in close contact with an inside of the pipe and a pressing force of which is adjusted by a spring is installed on the moving bo

Abstract: Provided is a method for digital rights management of a compressed file created by compressing one or more original files.

Abstract: Provided are a computing device provided with a DLL injection function and a DLL injection method. When receiving from an operating system notification of whether a target process corresponding to a program ordered by a user to be executed is created, a process creation module of an injection program executes a launcher process to create the target process as a child process of the launcher process and sets the target process to a suspend mode. A code insertion module receives allocation of a memory region where the target process is stacked, using a process handle of the target process, to insert a code for executing a DLL file to be injected into the target process. A restoration module cancels the suspend mode of the target process to allow the target process to be executed.

Abstract: Disclosed are a malicious code real-time inspecting device in a DRM environment and a recording medium for recording a program to execute a method thereof. A DRM module performs decryption and encryption during file reading/writing operations through a handle after confirming user rights relating to a file on the basis of a handle of a file having DRM applied when an execute command is inputted, outputs an inspection request message including a handle and a path of a file, and determines whether to perform an open operation of a file according to a malicious code inspection result on a file. A malicious code inspecting module inspects whether an original file, which is to be decrypted and read by the DRM module, is infected by malicious code or not on the basis of a handle and a path of a file in an inspection request message delivered from an interface module. According to the present invention, whether a document encrypted with DRM applied is infected by malicious code is inspected and treated in real-time.

Abstract: Disclosed are a refrigerator and a method of manufacturing a door of the refrigerator. The door includes a door frame formed with at least one opening, at least one front panel coupled to a front surface of the door frame to open or close the opening, a rear panel coupled to a rear surface of the door frame to form a foaming cavity together with the front panel and provided with a rack receiving water bottles, and a decorative member formed at a front surface of the front panel. A chamfer is formed at an edge portion of the door frame.

Abstract: Disclose is a method and system enabling joint viewing of moving picture while chatting. In order to match the screen being played and chatting message, a method for synchronizing contents playing times for the contents being played is further disclosed. A room master client among user clients joined the joint viewing room receives buffering state information from all clients in joint viewing and transmits playback start message to the clients in joint viewing according to the buffering state information. After contents playback is started, the room master client provides information on current contents playing time to the other user clients periodically, and the other clients synchronize contents playing times based on the current contents playing time of the room master client.

Abstract: An electronic money management method and system using a mobile phone is provided, which can be applied to electronic transactions. Upon receiving a request regarding electric money such as issuance, recharging, transfer, or balance checking, together with a mobile phone number and a password, from a user, an ARS server, an electronic money management web server, or an mobile communication service system transmits an authentication number to the user's mobile phone, compares the transmitted authentication number with one received from the user, and transmits the password and phone number to make the request if the authentication numbers are identical. The electronic money management server fulfills the request regarding electronic money, received from the one server or system, for an electronic money account identified by the password and mobile phone number, and transmits the fulfilled result and the account balance to the mobile phone through the one server or system.

Abstract: A method for making a metallic keypad includes the steps of forming a key using thermoplastic resin through an injection molding process, forming a conductive layer on a surface of the key, marking a function sign on the conductive layer, and forming a metal layer on the conductive layer except for the function sign.

Abstract: A method for managing walsh code channels in a mobile communication system includes the steps of initiating a plurality of walsh codes for the unit of sector and frequency at a base station, dividing the walsh codes allotted from the base station to a terminal in response to peak factor characteristic to put excellent walsh codes in a main queue and poor walsh codes in a sub queue, allotting with priority walsh codes which are on standby in the main queue at the base station if the terminal requests allocation of the walsh codes, and allotting walsh codes which are on standby in the sub queue if the allotted walsh codes are null or if there are no walsh codes having excellent peak factor characteristic. Accordingly, it is possible to minimize interference exerted on adjacent channels during communication, thereby improving quality of service in the overall communication system.
