The control unit 11 includes a first reference electroencephalogram measurement means 111, a scent electroencephalogram measurement means 112, a second reference electroencephalogram measurement means 113, a first sensitivity output acquisition means 114, a second sensitivity output acquisition means 115, and main elements. Determination means 116 and scent selection means 117 are provided. The storage unit 12 includes a reference brain wave storage unit 121, a first reference brain wave storage unit 122, a scented brain wave storage unit 123, and a second reference brain wave storage unit 124.

  Hereinafter, each process is demonstrated about the selection method and apparatus 10 of the fragrance which concerns on embodiment of this invention, referring FIGS. 1-8.

[First step]
In the first step (S1 in FIG. 1), a plurality of sensitivity phrases related to the body fluid absorbent article are set. The sentiment phrase accepting unit 110 sets a plurality of sentiment phrases input by the input unit 13 as sentiment phrases used in each process described later. For example, the emotional phrase receiving unit 110 displays a predetermined input screen on the output unit 14 and prompts the input field in the screen to input the emotional phrase. When the emotional phrase is input in the input field, the emotional phrase receiving unit 110 receives the plurality of emotional phrases input by the input unit 13 and stores them in the storage unit 12. Here, in this embodiment, a sensitivity phrase refers to an expression that symbolizes an impression when a subject smells a scent. For example, there are expressions that show the mood and emotions that are recalled when smelling a scent such as “relaxed” and “exhilarating”, and it is preferably an expression that shows the good feelings and emotions. In this embodiment, as shown in FIG. 2, “relaxed”, “happy”, “exhilaration”, “easy”, “gorgeous”, “crush”, “energetic”, “cute”, “clean” It is assumed that 10 words of “na” and “warming” are set.

  The sensitivity phrase can be set according to the target product to which the scent is attached, and is not limited to the expression set in the present embodiment. In addition, any emotional phrase can be set. For example, you may refer to the results of marketing surveys, etc., such as expressions that have been used frequently in the past for the target product or expressions that can easily attract the consumer's attention when attached to a product. A dictionary database in which a plurality of words are registered in advance may be prepared and arbitrarily extracted.

  In the present embodiment, language expression is used as the sensitivity phrase, but the present invention is not limited to this, and any combination of graphics, colors, characters, graphics, colors, or the like may be used.

[Second step]
In the second step (S2 in FIG. 1), each emotional phrase is individually recalled, and the brain wave at that time is measured and processed as a first reference brain wave.

  First, a plurality of subjects are individually seated on a chair, and an electroencephalogram is measured for 30 seconds by the first reference electroencephalogram measurement means 111 with the eyes closed and rested (rest electroencephalogram). This electroencephalogram is processed by an electroencephalogram fractal dimension analysis method to become a resting electroencephalogram after processing. This resting electroencephalogram is stored in the reference electroencephalogram storage means 121.

  Thereafter, with the subject's eyes closed and rested, the ten emotional phrases shown in Table 1 of FIG. 2 are recalled, and the first reference electroencephalogram measurement means 111 recalls the electroencephalogram when each emotional phrase is recalled. Is measured for 30 seconds and processed. In this embodiment, since the sensitivity phrase is 10 words, the first reference brain wave is measured 10 times for one subject. Then, the first reference electroencephalogram for each sensitivity phrase is processed by an electroencephalogram fractal dimension analysis method to obtain a processed first reference electroencephalogram. The processing after the measurement of the electroencephalogram is performed by the electroencephalogram fractal dimension analysis method of Non-Patent Document 1. Further, the first reference electroencephalogram measurement means 111 stores the first reference electroencephalogram in the first reference electroencephalogram storage means 122.

  In the fractal dimension analysis method, a fractal dimension analysis is performed on a difference signal between channels of biological signals measured in multiple channels (in this embodiment, an electroencephalogram). In the present embodiment, as described in Non-Patent Document 1, processing is performed using a method using a q-th moment. Thereby, a sensitivity tensor and a via spectrum can be obtained.

  The measurement of the electroencephalogram can be performed by an existing measurement method. For example, the measurement can be performed by a method disclosed in Non-Patent Document 1. In the present embodiment, 16 electrodes are arranged on the subject's head, and a plurality of types of electroencephalogram signals are measured. The same applies to the subsequent electroencephalogram measurements.

[3rd process]
In the third step (S3 in FIG. 1), the scented electroencephalogram measuring means 112 measures and processes each scented electroencephalogram when smelling a plurality of scents, and acquires the processed scented electroencephalogram. The plurality of scents are scents that are r types of candidates for the target product. In the third step, the panty liner is individually scented, the subject is scented for each of the plurality of scents, and the brain waves at that time are measured. The brain wave measured here is defined as a scented brain wave. The scented brain wave is stored in the scented brain wave storage means 123. In this embodiment, r = 6, but preferable r is 1 to 10. When r exceeds 10, it is difficult to obtain a stable electroencephalogram because the subject's senses are paralyzed.

  In this embodiment, six types of scents including the scents of Sample A to Sample D were used. Then, let the subject take the panty liners with each of the six types of scents, open them, and smell them with the eyes closed in front of the face. And the scent electroencephalogram measurement means 112 measures the electroencephalogram when smelling the scent for each sample for 30 seconds. Therefore, the scented electroencephalogram is measured r times for one subject. These scented electroencephalograms are processed by an electroencephalogram fractal dimension analysis method to obtain a processed scented electroencephalogram. The scented electroencephalogram measuring unit 112 stores the scented electroencephalogram in the scented electroencephalogram storage unit 123.

  Although it does not specifically limit as a specific example of a scent component, if an example is given, the scent component of the sample A of this embodiment will be p-tbutyl- (alpha) -methylhydrocinnamic acid aldehyde in a chemical substance as a main component. 1- (1,2,3,4,5,6,7,8-octahydro-2,3,8,8-tetramethyl-2-naphthalenyl) ethanal, 4,6,6,7,8,8 -A mixture of hexamethyl-1,3,4,6,7,8-hexahydrocyclopenta [g] [2] benzopyran, methyl (2-phenyl-3-oxocyclopentyl) acetate, hexylcinamic aldehyde alpha, Other essential oils include peppermint, lemon, and basil.

  In the chemical substance, the scent component of Sample B is methyl (2-pentyl-3-oxocyclopentyl) acetate, 1- (1,2,3,4,5,6,7,8-octahydro-2, 3, 8,8-tetramethyl-2-naphthalenyl) -ethanone, ethylene brushate, pt-butyl-α-methylhydrocinnamic aldehyde, 4,6,6,7,8,8-hexamethyl-1,3,4 , 6,7,8-hexahydrocyclopenta [g] [2] benzopyran, and also contains ylang ylang and Bulgarian rose as essential oils.

  The scent component of the sample C is a chemical substance containing hexylcinamic aldehyde, lyial, linalool, and dipropylene glycol as main components.

  The scent component of Sample D is a chemical substance containing linalool, methyl dehydrojasmonate, benzyl acetate, and dipropylene glycol as main components.

  In addition, the component of the scent attached to each sample is arbitrary, can be arbitrarily selected and blended according to the type of scent as a candidate, and is not limited to the type and number of components listed in the present embodiment. .

[4th step]
In the fourth step (S4 in FIG. 1), the second reference brain wave when recalling the most preferable scent for attaching to the panty liner is measured and processed. Specifically, based on a plurality of scents smelled in the third step, the subject is reminded of the most preferable scent (= ideal scent) to be attached to the panty liner, and the second reference electroencephalogram measurement means 113 then Measure and process brain waves. The electroencephalogram measured in the fourth step is set as the second reference electroencephalogram. This second reference electroencephalogram is measured once for one subject. The second reference electroencephalogram is also processed by the electroencephalogram fractal dimension analysis method to obtain a processed second reference electroencephalogram. Then, the second reference electroencephalogram measurement means 113 stores the second reference electroencephalogram in the second reference electroencephalogram storage means 124.

  Therefore, the reference EEGs are the 10 first reference EEGs obtained by measuring the EEG when the subject is reminded of 10 words of the emotional phrase, and the EEG when the subject is reminded of the most preferred scent for the pantilina A total of 11 electroencephalograms of the 1st second reference electroencephalogram obtained by measuring the above are processed by fractal dimension analysis.

[5th step]
In the fifth step (S5 in FIG. 1), each sensitivity phrase obtained by comparing the reference brain wave obtained from the difference between the rest brain wave after processing and the first reference brain wave after processing with the scent brain wave after processing The first sensitivity output is obtained. In detail, the 1st sensitivity output acquisition means 114 compares the reference brain wave for every 10 words sensitivity phrases, and two fragrance brain waves, respectively, and calculates | requires a 1st sensitivity output by the fractal dimension analysis method. For example, the method disclosed in Non-Patent Document 1 can be used as a method for obtaining the sensibility output.

[6th step]
In the sixth step (S6 in FIG. 1), each sensitivity phrase obtained by comparing the reference brain wave obtained from the difference between the rest brain wave after processing and the second reference brain wave after processing with the scent brain wave after processing The second sensitivity output is obtained. Specifically, the second sensitivity output acquisition unit 115 compares the reference brain wave when recalling the most preferable scent to be attached to the panty liner and the two scent brain waves, and outputs the second sensitivity output by the fractal dimension analysis method. Ask. As the fractal dimension analysis method, for example, the method disclosed in Non-Patent Document 1 can be used as in the fifth step.

[7th process]
In the seventh step (S7 in FIG. 1), the main element of the preferred scent required for the panty liner is determined from the plurality of sensitivity phrases from the correlation between the second sensitivity output and the first sensitivity output for each sensitivity phrase. To do.

Ｓｎ：（目的変数）第２感性出力
Ｘｎ，ｉ：（説明変数）第１感性出力
ｎ ：被験者数
ｒ ：香り
ｉ ：感性フレーズ Specifically, the main element determination unit 116 uses the second reference brain wave and the second sensory output obtained from the scent brain wave when recalling the most preferable scent for the panty liner as a target variable, and the first sensory output for each sensitivity phrase. The main element of the fragrance is determined from the sensibility phrases by multiple regression analysis using as an explanatory variable. Specifically, the main element determination unit 116 performs calculation processing using the following formula. In this embodiment, n = 29 people, r = 6 types, and i = 10 types.

Sn: (objective variable) second sensitivity output Xn, i: (explanatory variable) first sensitivity output n: number of subjects r: fragrance i: sensitivity phrase

  As a result, the sensitivity phrase having the highest correlation between the scent and the sensitivity phrase most preferable for the panty liner is determined as the main element of the scent. That is, it is possible to obtain a sensibility phrase preferable for expressing the most preferable scent for the panty liner.

  The result of the seventh step can be represented by a graph 2 as shown in FIG. 3 by multiple regression analysis. In the present embodiment, it can be seen that the sensitivity phrase “gorgeous” among the sensitivity phrases of 10 words has the highest correlation, followed by “easy” and “exhilaration”. Therefore, in this embodiment, the sensitivity phrase that is the main element of the scent is determined to be “gorgeous”. Note that the main element means a highly sensitive sensibility phrase, and may be an index in scent selection, and is not necessarily one.

Ｘｎ，ｉ：第１感性出力
Ｗｎ，ｉ：第２感性出力
ｎ：感性フレーズ
ｒ：香り
ｉ：被験者数 [8th step]
In the eighth step (S8 in FIG. 1), the first sensibility output in the main element of the sensibility phrase is used as an index (in this embodiment, “gorgeous”), and a preferred scent is selected from a plurality of scents. Specifically, the scent selecting means 117 uses the following formula 2 as the index of the first sensibility output for each sensibility phrase with respect to the main elements of the scent obtained in the seventh step, and the scent selection phrase and scent with the highest value Find a combination with.

Xn, i: first sensitivity output Wn, i: second sensitivity output n: sensitivity phrase r: fragrance i: number of subjects

  The results of calculating the value y using Equation 2 for each scent of sample A and sample B are shown in FIGS. The reason why the number of subjects i decreased from 29 in the seventh step to 23 was because six subjects with low correlation were excluded by multiple regression analysis. 4 is a diagram showing the results for the scent of sample A, FIG. 5 is a diagram showing the results for sample B, FIG. 6 is a diagram showing the results for sample C, and FIG. It is a figure which shows the result about.

  In sample B and sample C, there was almost no difference in the result of summing the y values for the ten emotional phrases. However, it can be seen that there was a large difference in the distribution of the y values for the individual emotion phrases.

  In samples A and B, the value of “gorgeous”, which is the sensibility phrase that became the main element of the fragrance in the seventh process, is high, but in samples C and D, conversely, the value of “gorgeous” sensibility phrase is low. Show.

  Therefore, it can be seen that the scent of sample A is the preferred scent for “gorgeous” which is the sensitivity phrase that is the main element of the scent. Then, samples A and B are selected as the most preferable fragrance to be applied to the panty liner.

[Apply to product]
By the scent selection method according to the present embodiment, the most preferable scent to be attached to the panty liner can be selected. The brain wave when smelling a scent or recalling a sensibility phrase tends not to be influenced by the surrounding environment. In particular, when the subject smells a certain scent or fills in a subsequent questionnaire, if any emotional phrase is displayed, the emotional phrase viewed by the consumer is not greatly affected. For example, a sensibility phrase such as “Relievely Relief” is attached to the product packaging, and in fact, even if the expression and incense tone do not match, as if the panty liner had a fruity image scent, A result that is not different from the result when the expression is not added can be obtained. In this respect, objective scent selection is possible by eliminating external factors in scent selection.

<Body fluid absorbent article with fragrance>
The bodily fluid absorbent article of the present invention is obtained by attaching the fragrance selected by the above fragrance selecting method to a bodily fluid absorbent article such as a panty liner. From this embodiment, the sensual phrase “gorgeous” is an objective main element in the pantilina, and the sample A having a high scent of this main element is the most preferable fragrance in the pantilina among the fragrances r. Can do.

<Body fluid absorbent article packaging>
In addition, the package body which attached | subjected the sensitivity phrase used as the said main element, or a phrase similar to this to the packaging container of the said body fluid absorbent article is also the body fluid absorbent article package of this invention. Here, a similar phrase means a related phrase related to a sensitivity phrase as shown in FIG. In this embodiment, the scent of sample A is added to the phrase “luxury”, which is the sensitivity phrase that has become the main element of the fragrance, or the phrases “luxury”, “luxury”, etc., that are related phrases. Can be displayed on the panty liner package.

  By attaching the sensitivity phrase that has become the main element of the scent to the package of the body fluid absorbent article, the sensitivity phrase that expresses the most preferable scent to be applied to the panty liner is displayed on the package. Thereby, when a consumer visually recognizes the sensitivity phrase displayed on the package, the consumer can foresee that the most preferable scent is attached to the panty liner. And a consumer can smell the fragrance with the highest affinity to the said sensitivity phrase, when opening a package. As a result, in addition to the impression generated from the sensibility phrase, the scent that has the highest affinity for the sensibility phrase can be given to the customer, giving them a sense of security and satisfaction that they were able to smell the scent as expected. it can. For this reason, it can contribute to the improvement of the purchase intention of a product.
