The food poisoning by the O157 escherichia coli in 1996 did not end in one prefecture and expanded to many other prefectures, in which 9314 patients and 11 dead patients were totally found in that year.
O157 esch e richia coli possesses the same toxin, named verotoxin, as the dysentery bacterium. The verotoxin does not cause only the hemorrhage of intestines, but causes also heavy troubles in kidniys like hemolytic uremic syndrome, because the toxin enters to blood flow from intestine walls and sometimes causes death for infected patients.
The adults often recover only showing diarrhea, w hen they get this disease. Therefore adults like to become healthy germ carriers, and make other people to be infected that disease. The children often become heavy, when they are infected. The adults must be careful for infection to others, when having loose bowels. They must attend to hygiene such as keeping their hands clean, and cooking room, cooking apparatus and food materials also clean.
Treatment must be carefully performed while seeing the state of the patient, administering some antibiotics like new quinoron for 4 to 5 days, because verotoxin is discharged from a broken bacillus in the patients.
The Ministry of Health and Welfare has corresponded the enterohemorrhagic escherichia coli infection syndrome as a specified communicable infectious disease, based on the treatment of the legal communicable disease, but a lot of this infection syndrome found even in 1997,1998.

The present study examined safety awareness and behaviors among elementary, junior high and senior high school students by a quesitionnaire survery. By the exploratory factor analysis and multiple regression analysis, the factors of question items were extracted and the causal structure was explained among safety behavior and other factors. Furthermore, a structural model was confirmed by covariance structure analysis.
Secondly, based on five factors explained by the factor analysis of question items, the safety self check sheet about safety competence were developed by the procedyre of standardization

It is necessary to enrich the systematic control of safety in the public facilities, workplaces, schools and communities to prevent the accident disaster for the safety of the person's life. Fundamentally, it is the most important to protect our lives by ourselves. As for the purpose of that, we must bring up the person who can find a dangerous situation, get rid of it and take safe behavior.
However, an examination about the safety competence that is a basis for safety behavior hasn't been done for not less than several years. Because of this, the research committee on safety competence was established by the Japanese Association of Safety Education, and it did the following research to build the basic theory that would be effective in the2lst century.
Formerly, there were three types of theory as to the safety competence: the theory of the elements that are necessary for accident prevention, the theory concerning coping with accidents, and the theory of psychosomatic function as safety competence.
Our committee tried to build new theory of the safety competence based on the previous investigation about the safety consciousness and behavior of students. We proposed the definition of safety competence and analyzed the structure of it. From our point of view, the core of the safety competence was humanity. Finally, we reached the conclusion that it was the most important for whom could do safe life to have better judgment and knowledge, and to acquire the sense of humanity and skills to do with accidents.
