Development of GMS data aquisition and database systems

It is well known that relativistic particles are hazardous to space equipments and astronauts, therefore it is important to monitor the space environment continuously. Since 1979 Hiraiso Solar Terrestrial Research Center has been watching the time sequence of high energetic particle flux everyday from the Space Environ- ment Monitor (SEM) onboard the Japanese Geostationary Meteorological Satellite. We developed a data acquisition system from the GMS-4 as well as its database system. The real time data plot, which is renewed every two minutes, has been presented by using http since 1994. We report the data acquisition system and the real time data display by means of the WWW browser along with the database system

Enhancement of the trapped radiation electrons at 6.6 Re during the storm recovery phase─Results from GMS/SEM observation─

We studies the correlation between the increment of relativistic electron flux at the geosynchronous orbit and the interplanetary magnetic field (IMF) properties as well as the magnetic disturbance signature during magnetic storms. Results demonstrates that the large flux enhancement has been made when IMF directed southward during the storm recovery phase

Modeling Skin Conductance Response Time Series during Consecutive Rapid Decision-Making under Concurrent Temporal Pressure and Information Ambiguity

Emergency situations promote risk-taking behaviors associated with anxiety reactivity. A previous study using the Iowa Gambling Task (IGT) has demonstrated that prespecified state anxiety predicts moderate risk-taking (middle-risk/high-return) after salient penalty events under temporal pressure and information ambiguity. Such moderate risk-taking can be used as a behavioral background in the case of fraud damage. We conducted two psychophysiological experiments using the IGT and used a psychophysiological modeling approach to examine how moderate risk-taking under temporal pressure and information ambiguity is associated with automatic physiological responses, such as a skin conductance response (SCR). The first experiment created template SCR functions under concurrent temporal pressure and information ambiguity. The second experiment produced a convolution model using the SCR functions and fitted the model to the SCR time series recorded under temporal pressure and no temporal pressure, respectively. We also collected the participants’ anxiety profiles before the IGT experiment. The first finding indicated that participants with higher state anxiety scores yielded better model fitting (that is, event-related physiological responses) under temporal pressure. The second finding demonstrated that participants with better model fitting made consecutive Deck A selections under temporal pressure more frequently. In summary, a psychophysiological modeling approach is effective for capturing overlapping SCRs and moderate risk-taking under concurrent temporal pressure and information ambiguity is associated with automatic physiological and emotional reactivity
