Definitions

  • the present invention relates to a risk evaluation system for perceiving the risk status of business operations, organizations and members by using each person as a sensor through observation of transition made in mental metrics such as the stress level of members involved in an organization and/or a business operation.
  • the measurement of stress has been carried out in order to understand health and mental conditions as well as for other medical purposes.
  • There has been a technique studied to realize reduction of mental stress by collecting data such as physiological quantity, subject quantity, behavior quantity and environmental parameters and analyzing a correlation among the collected data e.g. see Patent Document 1.
  • physiological reaction of a subject is measured in a physiological reaction measurement processor and the physiological reaction is used to obtain a physical index in a physiological indicator extractor.
  • the physiological index is converted into a living body parameter in a physiological quantity evaluation determination unit using a physiological model so that the living body parameter obtained through the conversion is compared to a preset pattern. Then, if these patterns match each other, a subject quantity data collector is made to collect a subject quantity of the subject.
  • Patent Document 2 There has also been a technique studied for providing a psychological test adapted to each social role (in the office, school or family) through the Internet for determination of the latent mental health of users (e.g. see Patent Document 2). According to the technique described in this document, a stress state in each social role is analyzed and grounds for the cause/process of unsoundness are presented to implement psychological support contents such as counseling for solving the issue.
  • Non-Patent Document 1 A research has also been carried out for the actual state of the stress of general public and the relationship between work accidents and the stress (e.g. see Non-Patent Document 1).
  • measurement techniques to allow easy stress measurement in daily life are enumerated such as measurement of physiological index (i.e. biological information), subjective/cognitive reaction and behavior reaction.
  • a member engaged in a business operation suffers from mental damage such as stress, a leave of absence and troubles may result in seriously affecting productivity and/or continuity of the business operation. Depending on a circumstance of the business operation, it may cause serious mental damage to members who are engaged in the business operation.
  • risk evaluation of contents of a business operation management and inspection are often carried out based on reports and material concerning the business operation.
  • this method may not determine whether a current business operation is good or poor. For example, even with excellent report contents, a business operation may be in a critical condition. Also, business inspection is often carried out subsequently, which does not necessarily enable risk evaluation in real time.
  • it is an objective of the present invention is to provide a risk evaluation system for evaluating the risk of business operations, organizations and members in real time based on transition of mental information of users.
  • the present invention provides a risk evaluation system comprising: measurement information storage means for storing mental information of each user time-sequentially; pattern information storage means for storing a reference pattern serving as information of transition of the mental information; and control means connected to measurement means for the mental information and output means.
  • the control means includes: means for obtaining mental information of each user from the measurement means to register the obtained mental information in the measurement information storage means; means for obtaining, from the pattern information storage means, a reference pattern relating to transition of the mental information; means for comparing, to the reference pattern, transition of the mental information recorded in the measurement information storage means; and means for outputting an alarm to the output means based on the comparison result.
  • a reference pattern regarding transition of mental information is obtained and the reference pattern is compared to transition of mental information recorded in measurement information storage means. Therefore, an abnormal condition of mental stress is detected based on a change and the risk state of business operations, organizations and members can be detected by using each person as a sensor.
  • the risk evaluation system may further comprise user attribute information storage means for storing attribute information of each user.
  • the control means further comprises means for obtaining the attribute information of each user and correcting a comparison method based on the attribute information.

  • mental information of a plurality of users can be used as a basis for risk evaluation of a business operation that is an aggregate of the users.
  • the risk evaluation system may further comprise business attribute information storage means for storing attribute information of each business operation.
  • the control means further includes means for obtaining the attribute information of each business operation and correcting a comparison method based on the attribute information.
