Abstract: The present invention is intended to provide a compound useful to analyze a vitamin D compound. The present invention provides an alkyne compound represented by Formula (I): where in Formula (I), A is a linear carbon chain having an alkynyl group at an end and having a vinyl group at another end; X1 is CH or 13CH; X2 is CHY, CDY, 13CHY, 13CDY, CO, 13CO, C18O, or 13C18O; m is an integer from 1 to 4; when m is 2 or more, X2s are identical or different; Y is H, D, NH2, 15NH2, OH, 18OH, SH, OR, O(CO)R, OSO3H, OSO3Na, or a sugar substituent; when Formula (I) contains two or more Ys, Ys are identical or different; R is an alcohol protective group, an alkyl group, an alkenyl group, or an aryl group; X3 is C or 13C; and at least one selected from the group consisting of X1, X2(s), and X3 is modified with a stable isotope D, 13C, 18O, or 15N.

Abstract: In an electronic conference system, an information display apparatus is provided, that allows to proceed with a conference efficiently even if performing a capturing of electronic data during the conference. The information display apparatus has a display device that is provided with a plurality of display modes and available for an electronic conference system, in which a connection of a data input device is monitored, and a processing method for the inputted data from the data input device whose connection has been detected is made different depending on the current display mode. In the processing method, when the display mode is a mode in which the data is editable and the inputted data is image data, the electronic conference system is caused to directly capture the data therein, and in the case except it, a storage dialog for the inputted data is displayed.

Abstract: An image processing apparatus is provided that is capable of displaying a customized screen without requiring direct input operations to the image processing apparatus. The image processing apparatus (for example, a multi-function peripheral, or MFP) is communicably connected to an information processing apparatus (for example, a personal computer, or PC) and includes a displaying portion. The MFP acquires user information related to a login user who logs in to the PC, authenticates based on the acquired user information to determine whether the login user is a usage permitted user who is permitted to use the MFP, and displays a customized screen corresponding to the login user on the displaying portion of the MFP when the login user is authenticated as the usage permitted user.

Abstract: An image processing apparatus is provided that is capable of displaying a customize screen without input operation to the own machine. An image processing apparatus (MFP) is communicatably connected to an information processing apparatus (PC) and includes a displaying portion. The MFP acquires user information related to a login user logging in to the PC, authenticates based on the acquired user information whether the login user is a usage permitted user permitted to use the MFP, and displays a customized screen corresponding to the login user on the displaying portion of the MFP when it is authenticated that the login user is the usage permitted user.

Abstract: When execution of a job is stopped by an error or the like, and when an uncompleted job is generated, the stagnation of the job is eliminated by enabling a user different from a requesting user of the job to cope with the uncompleted job. The user different from the requesting user inputs identification information through a user information input section 8. When recognizing the identification information, a permitting section 24 permits the recognized user to perform an operation to cope with the uncompleted job. When the user selects the uncompleted job and performs an operation to notify the uncompleted job, the notifying section 21 creates a message to notify that there is an uncompleted job, and transmits the message to a terminal apparatus 2 of the requesting user. A treatment section 22 deletes the uncompleted job or puts the uncompleted job on standby according to a response from the requesting user, so as to eliminate the stagnation of the job.
