Abstract: FRET measurement uses a FRET probe that includes a probe element X containing a donor fluorescent substance and a probe element Y containing an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. The modulation frequency of laser light with which the FRET probe is irradiated is adjusted to an optimum modulation frequency that maximizes a difference between the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET occurs and the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET does not occur.

Abstract: FRET measurement uses a FRET probe that includes a probe element X labeled with a donor fluorescent substance and a probe element Y labeled with an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. A test sample as a measuring object in FRET measurement contains a test object about which it is unknown whether or not it has an approaching/binding property of allowing the probe element X and the probe element Y to approach to each other or bind together or a separating property of separating from each other the probe element X and the probe element Y that are in a state where they adjoin each other or bind together. A plurality of sets of a fluorescence lifetime ?sample and a ratiometry Rsample obtained by this measurement are used to judge whether or not the test object has the approaching/binding property or the separating property.

Abstract: A fluorescence emitted by a measurement object at a measurement point is measured. When the fluorescence is measured, a measurement object is irradiated with laser light whose intensity is time-modulated by using a modulation signal at a predetermined frequency. Then, the fluorescence emitted by the measurement object is formed to a flux of the fluorescence having uniform distribution of light intensity, and a plurality of partial fluorescent signals are generated by receiving a plurality of divided portions of the flux of the fluorescence. At least some of the partial fluorescent signals are added altogether to generate a single fluorescent signal. Finally, a fluorescence relaxation time of the fluorescence emitted by the measurement object is calculated from the generated fluorescent signal by using the modulation signal. When fluorescence intensity of the fluorescence calculated from the fluorescent signal exceeds a predetermined threshold, the partial fluorescent signals to be added are limited in number.

Abstract: A computer network system for implementing a web page providing method is composed of a personnel management system of a user, terminals operated by respective employees belonging to the user, and a server, which are connected to each other via a network. The server stores an employee management table defining the respective roles of the employees' a content management table listing URLs for contents to be provided to the employees, a roll management table defining providable contents and conditions for providing the contents for every role, and a displaying attribute management table defining a work schedule of each of the employees. These tables are updated whenever new data is received from the personnel management system.

Abstract: A computer network system that executes a virtual outlet establishment mediation method is composed of a plurality of user terminals, a plurality of servicer terminals, and a single virtual outlet establishment mediation server that are capable of communicating via the Internet with one another. The virtual outlet establishment mediation server extracts one or more servicers whose desiring conditions (business group, region) match the attributes (business group, region) of a user. From the servicer or servicers extracted here, the virtual outlet establishment mediation server extracts servicers with attributes (product lineup, payment methods, delivery time, discount rate, point rate) that satisfy the conditions (product lineup, payment methods, delivery time, discount rate, point rate) desired by the user.
