People under chronic stress cannot have appropriate care without self-reported health status. If their mental stress is quantitatively estimated with small sensors and data mining technologies, we can know their variation of mental state in their daily life. Sharing the information with others will help them not get worse. An application for smart phones which can check the variation of mental state as a life log is discussed in this paper.

In this paper, we build a Generic Meta-norms Game which integrates positive reaction such as reward and negative reactionn such as punishment. We categorize the parts of the game using structural conditions and regions of attraction to cooperation. According the simulation results, some insights are derived such that one should use the second-level on rewarding or pun- ishment to keep cooperation. Also, we found that games which includes meta-reward are more effective to realize cooperation cominant system easily.
