example 1

[0108] In the above description, the estimation standard EC is set to classify the feature quantities of the physiological indexes into two stages of the feature quantities of the "normal" sample Sa and the feature quantities of the "abnormal" sample Sa. However, the estimation standard EC may be set to classify the characteristic quantities of physiological indexes into three or more stages. Thus, the symptoms of subject Su are estimated in more detail than the two-stage classification. The following description will be made through an example in which the feature quantities of physiological indexes are classified into four stages based on sample information or statistical processing.

[0109] First, an example of classifying the feature quantities of physiological indexes into four stages based on sample information will be described. The sample information acquisition unit 14 acquires sample information indicating the degree of symptoms from each sample Sa using the above-...

[0113] Next, when it is difficult to classify feature amounts based on sample information, an example of classifying feature amounts of physiological indexes into four stages based on statistical processing will be described. Similar to the example based on sample information, the sample information acquisition unit 14 acquires sample information indicating the degree of symptoms from each sample Sa using the above-mentioned questionnaire. The standard setting unit 15 classifies the feature quantities of the physiological indexes in the plurality of samples Sa into two stages, ie, "normal" and "abnormal", based on the sample information.

[0114] The criterion setting unit 15 sets the estimation criterion EC using the feature quantity space for each physiological index based on the classification result of the feature quantity. First, a machine learning algorithm is used to specify the boundary B between the range Rn of the feature quantity of the "normal" sample Sa (the "norm...

Abstract

Provided are an estimation device, an estimation system, an estimation method and a program, by which the occurrence or non-occurrence of jet lag can be objectively determined and the extent of jet lag symptoms can be quantitatively evaluated. The estimation device comprises: an acquisition unit (24) for acquiring estimation criteria (EC), said estimation criteria being set by, relative to a plurality of specimens (Sa) having different extents of jet lag symptoms, dividing the feature values of physiological indexes in the deep body temperature system and the feature values of physiological indexes in the active mass system individually depending on the extents of jet lag symptoms, and then specifying the feature value ranges (R) depending on the extents of jet lag symptoms thus divided;an extraction unit (23) for extracting the feature value of the physiological index in the deep body temperature system and the feature value of the physiological indexes in the active mass system of a subject (Su); and a symptom estimation unit (25) for determining the feature value ranges of the estimation criteria, within which the feature value of the physiological index in the deep body temperature system and the feature value of the physiological index in the active mass system of the subject respectively fall, and thus estimating the extent of jet lag symptoms of the subject.

Description

technical field [0001] The present invention relates to an estimating device, estimating system, estimating method and program of jet lag syndrome symptoms. Background technique [0002] Jet lag syndrome (in a broad sense) Deviation from circadian rhythm due to movement involving jet lag, shift work, irregular lifestyle (lifestyle habits with sleep phases that differ greatly between weekdays and non-workdays, or irregular sleep-wake habits), etc. affect the physiological state. Jet lag causes symptoms such as sleep disturbances and persistent fatigue. When the physiological state is affected by the symptoms of jet lag, the physical ability is reduced, and undesired accidents may occur. For this reason, from the viewpoint of physiological state management, it is desirable to objectively determine whether jet lag exists or to quantitatively evaluate the degree of jet lag symptoms. [0003] However, jet lag syndrome symptoms have individual differences, age differences, diff...
