The air we breathe is incontrovertibly the life-supporting substance but it is able to change suddenly to the life-damaging one. On the basis of the accumulated experiences during the history of us, human being, on the "smoke" to the chronic and/or acute respiratory diseases, especially after the tragic episode of December fog in London in 1952 when there were records of about 4000 excess deaths in Greater London for a two-week period during and after then, the various groups of investigators had studied the epidemiology of these kinds of the respiratory diseases according to the air pollutants with weather and climate. The subcommittee of the British Medical Research Council (BMRC) formulated a standard questionnaire in 1960. The whole products of replies from the objects must be employed for evaluation of BMRC questionnaire and then the various designated tests should be carried out simultaneously. The latter tests, however, have become gradually to be difficult to operate because of the changes in the social conditions. When the experienced questioners obtain acculately the outcome in the test with BMRC questionnaire in the formula of Chiba University, the characteristics of the inhabitants' health can be recognized by summing up the examination marks given to the symptoms in the individual form. The illustration for grading and evaluating BMRC questionnaire in this formula are given herein full accounts, the marks of which are given by weighting the objective symptoms as a whole under the regular procedures and illustrated in the cumulated frequency curve by figuring out the percentile in each class of the marks. Although only a few questions (for example, Q5 and Q10) are sometimes adopted for evaluating the judgement of the respiratory diseases, the evaluation of the prevalence rate of the mass should be performed on the evaluation of the state of the individual health. Therefore, this formula of Chiba University may be appraised from the point of view of evaluating the state of the individual health on the basis of the whole replies to the questionnaire and then the prevalence state of the mass from the cumulated frequency curves.
