    A study was performed for the purpose of developing the hig-efficiency paddy seed disinfection technique using dry heat air. In this study, the seeds carrying Pyricularia grisea, Gibberella fujikuroi or Burkholderia glumae were used as the test samples, and a study to confirm functions, a study on the effects of sterilization of/protection from bacteria, and verification of effects on germination, etc. were performed using the test system utilizing the fire of line burner with which heat disinfection with dry heat air can be performed and the test system with electric tubular furnace. As a result, for Pyricularia grisea, the disinfection rate of 100 % was achieved, which was higher than that by conventional treatment such as treatment with drug solution and hot water immersion method, and for Gibberella fujikuroi and Burkholderia glumae, the effect equivalent to or higher than conventional treatment was obtained. Moreover, there was no decrease in germination rate by the treatment under the same conditions.

    The GPXX format was devised for expression measurement data with space-time information collected by any sensors with GPS sensor. The GPXX format extends the GPX format, which is widely used as a GPS data exchange standard, by adding arbitrary measurement information to the space-time information expressed in the GPX format. One of the significant features of the GPXX format is that it can express information about the meaning and definition of arbitrary measurement information. Data input/output function by the GPXX format was implemented in existing software for farming data management, and the software was applied to process measured data collected by DigiFarmLogger, that was one of measurement systems for evaluation of the GPXX format. We confirmed that data processing by the GPXX format from the data conversion step to the visualization step worked well as we expected.
