Abstract: A compound represented by general formula (I) wherein all the symbols are as defined in the specification has a selective S1P5 receptor agonist activity due to having a linker from a phenyl group to a cyclic substituent in a dihydronaphthalene skeleton; i.e., due to having a short linker of one atom or less as L in general formula (I), and can therefore serve as an agent for treating S1P5-mediated disease, e. g., neurodegenerative disease such as schizophrenia.

Abstract: A compound of general formula (I-1): wherein the symbols are defined in the specification, has a selective S1P5 receptor binding activity and modulates the function of an S1P5 receptor, and can therefore be a therapeutic agent for a S1P5-mediated disease, for example, neurodegenerative diseases such as schizophrenia, Binswanger's disease and the like.

Abstract: A data transfer system is provided that, even in cases when the demands of the user are not concretely determined, can select the appropriate transferee for processing those demands.

Abstract: A work-flow system that manages a progression status without wasted effort even when the work comprises a plurality of jobs. A definition-information-memory unit that stores work-flow-definition information in which the job types and an order of processing are correlated beforehand, and a request-receiving unit receives jobs comprising mutually related tasks as one work project. Persons in charge and the order of processing are set for the received work by a person-in-charge-setting unit based on the work-flow-definition information. Also, when a task of a job is processed by a person in charge, a judgment unit determines whether or not other tasks of other jobs that are related to the task being processed have already been processed, and when it is determined that all of the other related tasks have been processed, a processing-approval unit approves processing the next tasks of that work.

Abstract: This invention is a data-management apparatus, data-management method and program thereof that improve convenience for a user that does not have authorization to access data without sacrificing the security of the data. This invention is a data-management apparatus, data-management method and program thereof that comprises a user-information-provider unit that provides information to the user about other users that are authorized to access data when the user is not authorized to access data.

Abstract: A system and method for maintaining confidentiality of the workflow process information and improving information accessibility for authorized persons are disclosed. A drafter's PC (200) inputs price setting information into a control server (100) through a LAN. An approver's PC (300) inputs approval status information into the control server through the LAN. The drafter's PC (200) and the approver's PC (300) can browse the inputted data. The control server (100) retrieves the approval status information but the price setting information from the inputted data according to a user database (130) and a security setting table (150), and sends the e-mail based on the information retrieved to the drafter's mobile phone (400) outside the LAN.

Abstract: A server 20 includes: a history database 25 for storing a provision history of product pages having been provided to a user terminal; an inquiry receiving unit 26 for receiving an inquiry from the user terminal; a history judging unit 27 for judging with reference to the history database 25 whether a predetermined product page has been provided to the user terminal; and an inquiry providing unit 29 for providing the inquiry and the judgment to a responder terminal. Being provided with the inquiry along with the judgment, a responder can make an appropriate response to the inquiry without going through unnecessary troubles.
