Abstract: An automatic traveling system includes: a setting processing unit that sets, to operation terminals and or an operator, an authority to give an instruction related to automatic traveling to a work vehicle on the basis of a predetermined condition; and a control processing unit that operates the work vehicle on the basis of an instruction given from the operation terminals and or the operator to which the authority is set.

Abstract: An operation status management method includes acquiring apparatus position information indicating a position of one or more work apparatuses that include a plurality of travel modes, and perform work in a field, and travel mode information indicating a travel mode of the work apparatus. The operation status management method also includes outputting work apparatus information indicating a position of the work apparatus and a travel mode of the work apparatus, in association with each other. The work apparatus information may indicate an image indicating a position of the work apparatus on a map. Further, the plurality of travel modes may include a manual travel mode in which the work apparatus is manually controlled by a worker riding on the work apparatus. Further, the plurality of travel modes may include an automatic travel mode in which the work apparatus is controlled from a control terminal communicably connected to the work apparatus.

Abstract: A work management method includes determining, based on operation information of a work device that performs work in a field, an operation status of the work device at each time. The work management method includes determining, based on the operation information of the work device, a ridge on which the work device performed work at each time. Furthermore, the work management method includes outputting work information indicating a display image, representing the operation status of the work device and the ridge on which the work device performed work in association with each other at each time.

Abstract: A position information display method includes acquiring position information indicating positions of a plurality of work devices, generating range information indicating a first range in which the positions are distributed on a predetermined map, calculating a scale for outputting display information including the first range, in map information representing the map, to a predetermined display region of a display device, and outputting the display information indicating the distribution of the positions in the first range based on the position information, the range information, and the scale.

Abstract: A work management method includes storing work data associating a determined work type that represents work performed in a first work region and has been determined with work region information that represents the first work region. In addition, the work management method includes estimating an estimated work type that represents work performed by a work device in a second work region, based on operation information that represents operation status of the work device. In addition, the work management method includes outputting region display information that distinctively represents the first work region corresponding to the determined work type and the second work region corresponding to the estimated work type that has not been determined.

Abstract: This work information management device includes: a tractor-side information acquisition unit for acquiring tractor-side information which includes position information of a tractor at each of specific times and operation information of the tractor at each of specific times, such tractor-side information being acquired from the tractor having mounted thereon any one of a plurality of types of work machines; and a work type estimation unit for estimating the work type of work that has been carried out by a work machine mounted on the tractor, on the basis of the tractor-side information acquired by the tractor-side information acquisition unit.

Abstract: A work information analysis device includes a work information storage unit in which work information relating to each of instances of work performed during different periods on a plurality of work areas that overlap at least partially is associated with the work area in which the work was performed and the result is stored. The work information analysis device further includes a selection unit for selecting desired information from among a plurality of pieces of information included in the work information as a parameter for sorting the work name of each instance of work. The work information analysis device also includes a display control unit for sorting and displaying the work names of each of the instances of work on the basis of the parameter selected by the selection unit.

Abstract: There is provided a broadcast receiving terminal that includes a reception unit, a display unit, and a reservation unit. The reception unit receives, over a network, content information, the content information including trailer information and reception reservation information. The display unit displays trailer content. The reservation unit reserves reception of the broadcast program.

Abstract: A medical tubing of a random copolymer containing an olefin-based monomer, such as ethylene, in an amount of 50-95 mol % and, preferably 75-95 mol %, and a styrene-based monomer, such as styrene, in an amount of 50-5 mol %, preferably 25-5 mol %. The medical tubing can be used as a conjugating tube or a connecting tube of medical equipment such as infusion circuits and blood circuits, and for administering an oil-soluble drug such as nitroglycerin. The random copolymer does not contain chlorine atoms or a plasticizer. The tubing has very small adsorption of the drugs, can withstand squeezing action by an infusion pump, has a possibility of undergoing &ggr;-ray sterilization and has flexibility necessary for clinical use.
