It is important to collect and spread accurate information quickly during disasters. Therefore, utilizing Twitter at the time of accidents has been gaining attention in recent year. In this paper, we propose a real-time information sharing system during disaster based on the utilization of Twitter. The proposed system consists of two sub-systems, a disaster information tweeting system that automatically attaches user's current geo-location information (address) and the hashtag of the form “#(municipality name) disaster,” and a disaster information mapping system that displays neighboring disaster-related tweets on a map.

In order to elucidate the interaction of lactic acid bacteria with the immune system, immune responses to the lactic acid bacteria, Bifidobacterium longum and Lactobacillus acidophilus, were examined in mice fed with each organism. In mice fed with B. longum for more than 8 weeks, an antibody response was detected to the cytoplasm of B. longum, but not to the cell wall. On the other hand, in mice fed with L. acidophilus for more than 6 weeks, an antibody response was detected to both the cytoplasm and cell wall of L. acidophilus. Moreover, feeding each organism for 2 weeks enhanced the proliferative response of Peyer's patch (PP) cells to the cell fraction against which the serum antibody was detected. However, this was not found with spleen cells. These results suggest that mucosal stimulation by lactic acid bacteria may induce a systemic immune response to them.
