Abstract: A non-transitory computer-readable storage medium storing a navigation monitoring program that causes at least one computer to execute a process, the process includes acquiring direction information that indicates a direction of a vessel and position information that indicates a position of the vessel; and predicting whether or not the vessel navigates along a course by inputting the acquired direction information and the acquired position information to a prediction model generated by machine learning by using direction information and position information for each of a plurality of vessels that has navigated in the past and a correct answer label that indicates whether or not each of the plurality of vessels navigates along a course.

Abstract: A mobile terminal periodically confirms the state of a takeover permission terminal (another mobile terminal) registered in takeover permission terminal information (S801). At this time, the mobile terminal determines whether or not a specific event (incoming call, power-off, etc.) has occurred on the takeover permission terminal (S802). If the mobile terminal has determined that a specific event has occurred on the takeover permission terminal, the mobile terminal confirms whether or not the mobile terminal is registered in the takeover side terminal information of the takeover permission terminal (S803). Then, if the mobile terminal is registered, the mobile terminal takes over the operation that the takeover permission terminal has performed (S804).

Abstract: Anticoagulative high-molecular composition which comprises a cellulosic polyelectrolyte complex formed from a polycationic cellulose derivative such as a quaternary ammonium salt of hydroxyalkyl cellulose, and a polyanionic cellulose such as sodium cellulose glycolate, which is used in the field of medical instruments or devices.

Abstract: This invention concerns a production process of an antithrombogenic and antiadhesive material which can favorably be used as artificial blood vessels, artificial valves, grafting patches for cardiovascular organs, artificial heart catheters and so on. The gist of this invention is constructed substantially of subjecting glycidyltrialkylammonium halide such as glycidyltrimethylammonium chloride to the reaction with a material comprising pure collagen or collagen and other components like mucopolysaccharide in order to introduce a cationic quaternary functional group in collagen molecules of the material and then subjecting heparin to the ionic combination with the cationic functional group introduced.
