In Japan, public health nurses decrease the frequency of home visit because of other works. Each frequency in 1998 and 2008 years is 2887953 and 327179 times. Its decrease may delay discovering abnormality. If nurses have no other method to catch the abnormality state except visiting, the abnormality can never be caught during interval. In addition, sensitive ability decreases with interval elongation. The quantity of feeling is directly proportional to the logarithm of irritation by Weber-Fechner's law. The quantity of irritation is equal to degree of changed energy per time. Very small abnormality can be sensed by the observation of same visitor with very short interval, mathematically. Both the visitor exchange and decreasing visit frequency not only decrease chance of "sensing" but also make it more difficult. The effect of interval time may be larger than it of ability. Very small abnormality cannot be sensed with interval elongation, even if sensitive ability of visitor is same.
