Abstract: An apparatus for managing the booking of travel products includes memory storing booking-related information including information on a booking confirmation date, travel departure date, number of booking persons, number of persons who have confirmed a booking, and minimum number of departure persons of a travel product and a processor determining, based on the booking-related information, a first travel product that is ahead of a booking confirmation date thereof and in which the number of booking persons is less than a minimum number of departure persons and a second travel product that is ahead of a booking confirmation date thereof and in which the number of booking persons is a minimum number of departure persons or more, and providing a booking person of the second travel product with a booking change suggestion indicative of a booking change into the first travel product.

Abstract: Proposed is an electronic device including a communication unit configured to exchange data with a plurality of servers, a memory configured to store the data; and a processor configured to perform operations according to commands stored in the memory, wherein the processor generates tour package management units, each having a plurality of attribute fields, determines at least one attribute field among a plurality of attribute fields as a reference attribute field corresponding to each of the servers, groups, for each of the servers, the tour package management units on the basis of the reference attribute field in each of the servers and thus generates a management unit group corresponding to each of the servers, and transmits the management unit group corresponding to each of the servers to each of the servers in such a manner that the servers generate unit tour items corresponding to the management unit group.

Abstract: Disclosed is an electronic device. The electronic device includes: a memory; and a processor configured to control the electronic device by executing instructions stored in the memory so that the electronic device determines a target customer suitable for selling a travel package, in which the memory stores purchaser information associated with actual purchasers who have purchased travel packages of a plurality of sellers and purchase history information associated with purchase histories of each of the purchasers, and the processor uses the purchaser information to generate virtual customers from a real purchaser, generate a test product for testing whether virtual customers make a purchase, and determine a target customer having high expected sales for the test product among the virtual customers.

Abstract: A phosphor is provided that has a host material that is doped with a dopant having the chemical structure XCl3, where X is a rare earth element or combination of elements. A free oxygen contributor is also added to provide the free oxygen necessary to activate the rare earth dopant. The processing of the phosphor includes the heating of the phosphor in an over pressure environment of zinc, cadmium or tellurium. The heating is done in a two-temperature zone enclosed environment, so that impurities in the phosphor powder are condensed out on the cooler surface. Altematively, the dopant may be a material that does not include a rare earth element, such as copper, tellurium, cadmium, silver, potassium, manganese, magnesium, calcium, strontium, and barium.
