Sexual addiction is classified as a type of psychiatric disorder, which is a symptom of societal success, but it is a symptom of trying to ascertain its existence through sexual adventure in a state of feeling lonely personally. Sexual adventure is a concept that includes sexual addiction and indiscriminate sexual experience. Former US President Bill Clinton and her sexual intercourse with female employees are considered to be examples of indiscreet sexual experiences.

These characteristics of sexual addiction include impulsiveness without the ability to control whether to continue or stop sexual behavior, the tendency to pursue sexual behavior in spite of problems, and the obsession to do other things all day long with sexual imagination have.

In the past, it was necessary to rely on the judgment of a person who is closely related to the person or the person with whom the person was sexually addicted. Since the degree of sex addiction was measured through a simple test or a questionnaire, There is a problem in that it is difficult to do.

In addition, since sex addiction is related to inner psychology of a person, it is difficult to objectify and it is difficult to diagnose accurately.

Therefore, there is a need for studies on how to accurately and effectively determine sexually addiction in order to induce early treatment.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. In addition, the embodiment described below does not unduly limit the contents of the present invention described in the claims, and the entire configuration described in this embodiment is not necessarily essential as the solution means of the present invention.

With the recent improvement in quality of life, interest in mental satisfaction as well as material abundance is increasing. Sexual addiction is spreading to social problems with increasing importance of mental happiness, but it was difficult to accurately diagnose such sex addiction by using objective indicators.

The present invention proposes a method to more accurately and efficiently identify a sex addict using functional magnetic resonance imaging.

<Constitution of sex addict discriminator>

Hereinafter, with reference to FIG. 1, a sex-addict discriminator 100 using standardized sexual arousal induction and functional magnetic resonance images to be proposed by the present invention will be described in detail.

FIG. 1 shows an example of a block diagram of a sex addict discriminator using standardized sexual arousal induction and functional magnetic resonance imaging of the present invention.

1, the sex addict discriminating apparatus 100 may include a discriminating model generating module 10, a functional magnetic resonance imaging apparatus (fMRI) 20, a sex addict discriminating module 30, and the like. However, the components shown in FIG. 1 are not essential, so that a sex addict discriminator 100 having more or fewer components may be implemented. Also, it is possible that the components shown in FIG. 1 are connected to each other in an interdependent manner, and that the components are separately or integrally implemented as shown in FIG.

Hereinafter, the components implementing the sex-addict discriminator 100 of the present invention will be described in order.

First, the discrimination model generation module 10 is configured to generate a discrimination model for judging whether or not a sex addict is present. The discrimination model generation module 10 may include a sexual arousal inducing unit 12, an image processing unit 14, and a discrimination model deriving unit 16 have.

The sexual arousal inducing unit 12 induces the sexual excitement of the subject by subjecting the subject to the sexual arousal induction process. In the sexual arousal induction process, the stimulus presentation period and the rest period are repeated. During the stimulation presentation period, the standardized sexual stimulation image or the neutral image is presented to the subject to perform sexual arousal and no work is performed during the rest period.

This stimulus presentation paradigm can be implemented with a block - based and event - based paradigm depending on its structure. In the block-based paradigm, the activation period and the idle period are repeatedly configured for a relatively long period of time, and the active period is configured to be much shorter than the idle period in the event-based paradigm.

The image processing unit 14 is connected to the functional magnetic resonance imaging apparatus 20 and uses the brain image of the subject acquired by the functional magnetic resonance imaging apparatus 20 to measure blood oxygen levels And the like. The image processing unit 14 generates cerebral activation information data of the subject based on the measurement result, and the cerebral activation information data may be generated in each of the stimulus presentation period and the pause period.

When a certain area of the brain activates, oxygen is initially used to reduce the amount of oxygen compared to other areas using oxygen, but after 2 to 4 seconds, blood flow increases with blood glucose and oxygen supply temporarily. Temporarily supplied oxygen is supplied in excess of the required amount, and the signal due to the difference in hemoglobin and deoxygenated hemoglobin concentration combined with oxygen generated at this time is cerebral activation information data.

The discriminant model derivation unit 16 generates a discriminant model for discriminating sex addiction based on the cerebral activation information data generated by the image processor 14. Specific methods for deriving the discrimination model will be described later.

Next, the functional magnetic resonance imaging apparatus (fMRI) 20 can acquire the brain image of the subject, and can use this information to determine which area of the subject's brain is being used and the degree of activation of the brain.

Specifically, the functional magnetic resonance imaging apparatus 20 can visualize the difference in the signal resulting from the concentration difference between oxygen-bound hemoglobin and deoxyhemoglobin. That is, while the sexual stimulation is generated in the subject located in the functional magnetic resonance imaging apparatus 20 by the process of inducing the sexual arousal, the image processing unit 14 acquires the subject's brain image acquired by the functional magnetic resonance imaging apparatus 20 The signals corresponding to the blood oxygen concentration in each brain region of the subject can be measured over time, and the image processing unit 14 can generate cerebral activation information data based on the measurement results.

The functional MRI device 20 of the present invention is preferably based on an event-based paradigm. In the event-based paradigm, we can observe the blood oxygen concentration-dependent signal accompanied by each event of the presented stimulus. The time-averaged fMRI data obtained before and after the presentation time of the stimulus are averaged, Blood oxygen concentration-dependent signals can be separated from artifacts and noise.

This method is different from the block-based paradigm because it has the advantage of being able to observe the temporal change of the hemodynamic response and to observe the response to the emotional and cognitive functions that occur instantaneously like the sexual excitement. Therefore, the cognitive and emotional Dynamic trends of factors can be grasped. In addition, the event-based paradigm is more advantageous than the block-based paradigm in that it can reduce the habit of stimulation and increase concentration on the stimulus.

Next, the sex addict discrimination module 30 determines whether the subject is a sex addict by applying the discrimination model generated by the discrimination model derivation unit 16 to the actual subject. In order to apply the discrimination model to the subject, a sexual arousal induction process must be performed to induce the sexual excitement of the subject, and the brain image of the subject must be acquired using the functional magnetic resonance imaging device 20, The region of interest and its BOLD value should be extracted.

<How to derive a discriminant model for sex addict discrimination>

Hereinafter, a method for deriving a discriminant model for discriminating sexually addicted persons using the standardized sexual arousal induction and functional magnetic resonance images to be proposed by the present invention will be described in detail.

FIG. 2 is a flowchart showing an embodiment of a method for deriving a discrimination model for discriminating sexually addictive patients according to the present invention.

Referring to FIG. 2, in order to induce sexual excitement of a subject, the sexual arousal inducing unit 12 performs a sexual arousal induction process on a subject (S100). Here, the subject is a test group for deriving the discriminant model, and is composed of sex addiction group and normal group.

Stimulation of sexual arousal induction During the presentation period, stimulus images are presented to the subject and irritation images are removed during the rest period. The stimulus image presented to the subject during the stimulus presentation period is a standardized sexual stimulus image or a neutral image independent of sexual arousal.

3 to 5 show an example of an image presented in the stimulus presentation period and the rest period of the sexual arousal induction process that can be applied to the present invention. FIG. 3 shows a normalized sexual stimulation image, FIG. 4 shows a neutral image independent of sexual arousal, and FIG. 5 shows an image of a resting period in which a stimulus image is removed.

In the sexual arousal induction process, the standardized sexual stimulation image or the neutral image is presented to the subject for a certain period of time, and the image of the rest period as shown in Fig. 5 is presented to clear the afterglow of the stimulus.

The length of the stimulus presentation period of this paradigm can be set to 10 seconds or less, and the period of rest is considered to be the time for returning the initial stable state of the neural activity due to stimulus presentation, increasing the cerebral signal detection power and effectively removing noise And can be set to various values ranging from 7 to 13 seconds.

Here, the standardized sexual stimulation image is selected from a plurality of sexual stimulation images by a participant having a predetermined number of persons or more. The participant judges the suitability and effectiveness of the sexual stimulation for multiple sexual stimulation images, and the standardized sexual stimulation image is determined by this judgment. The fitness is related to the occurrence of sexual arousal by the sexual arousal image, which is related to the degree of sexual arousal by the sexual arousal image.

The selection of the standardized sexual stimulation image will be briefly described with reference to FIG. FIG. 6 shows a normalization process of a sexual stimulation image used in the process of inducing sexual arousal, which can be applied to the present invention.

Referring to FIG. 6, 58 adult men aged 20 to 31 years were subjected to a stimulation evaluation task. All of these participants are normal people who have not been diagnosed due to problems with sex addiction.

Consider participants' sexual images with mixed sexual stimulation and control stimuli, assessing their perceived sexual desire for each. The participant sees five seconds of visual stimulation and evaluates his / her feelings on the psychological evaluation scale for the scene on a seven-point scale.

The results are analyzed and the final 20 standardized sexual stimulation images are selected. The final visual stimuli have an average of 86.15% fitness and 5.59 points (7 out of 10). The measured efficacy index can be used to induce sexual arousal at a desired intensity.

Referring again to FIG. 2, the brain image of the subject is acquired using the functional magnetic resonance imaging apparatus 20 (S110). The image processing unit 14 can measure a signal corresponding to the oxygen concentration in blood in a plurality of areas of the subject's brain using the brain image of the subject and generate cerebral activation information data based on the measurement results have.

Next, the image processing unit 14 performs a preprocessing process on the brain image acquired by the functional magnetic resonance imaging apparatus 20 (S120). The image processing unit 14 corrects an error of the cerebral activation information data through several preprocessing steps. The process can include steps such as measurement time difference correction, head motion correction, spatial standardization using my anatomical images, spatial standardization using the standard brain image developed by the Montreal Neurological Institute, and spatial smoothing.

Then, the discriminant model derivation unit 16 extracts a region in which activation occurs in the subject's brain in the process of inducing sexual arousal (S130). The discriminant model derivation unit 16 compares the cerebral activation information data generated during the stimulus presentation period with the cerebral activation information data generated during the pause period and determines whether or not a predetermined threshold value or more of the plurality of regions of the subject's brain It is possible to extract the active region where the activity occurs.

Specifically, the preprocessed data undergoes some statistical reasoning. Personalized neuronal activation patterns are estimated using a general linear model with regression coefficients of pre - processed cerebral activation information data and behavioral response data on sexual arousal. After calculating the parameter estimates of the general linear model and converting them into useful statistical values, the signal level map of the cerebrum can be generated by statistically processing the images between the stimulus presentation period and the rest period.

Then, the discriminant model derivation unit 16 extracts a blood oxygen concentration (BOLD) value in the ROI and the ROI (S140). The discriminant model derivation unit 16 compares the cerebral activation information data of the sex addiction group with the cerebral activation information data of the normal group. Based on the contrast result, the difference between the activity of the sex addiction group and the activity of the normal group It is possible to extract a region of interest having a predetermined threshold value or more. In addition, the blood oxygen concentration value in the region of interest can be extracted by time zone. These values are generated in the stimulation presentation period and the rest period, respectively.

In other words, we use the statistical brain map of the brain activation information of the sex addiction group and the normal group to perform the analysis of the pixels on a pixel-by-pixel basis, and extract a meaningful region having a difference of more than the threshold value. The standard brain image data developed by the Montreal Neurological Institute is used to give an anatomical name to the extracted region. The brain regions of the activated multiple brain regions can be designated as the brain regions of interest in which the sex addictive group exhibits higher activation than the other brain regions as compared to the normal group or the normal group as compared with the sex addiction group.

FIG. 7 shows the difference in activity between the sex addiction group and the normal group in a specific region of the brain, which can be obtained according to an example of the present invention. Referring to FIG. 7, a minimum independent variable (a minimum number of brain signal values capable of distinguishing between two groups) among the brain regions that differ between the sex addiction group and the normal group is selected, and the signal value of the selected brain region The optimal discriminant function can be derived by dividing the two groups.

Referring again to FIG. 2, the discriminant model derivation unit 16 generates a discriminative model for discriminating sex addicts (S150).

FIGS. 8 to 11 show the derivation process of the discrimination model according to an example of the present invention. The process of deriving the discrimination model is the same as the process of generating the discriminant function distinguishing between the sex addiction group and the normal group of FIG. 8, the process of verifying the discriminant power of the discriminant function using the structure matrix of FIG. 9, And a process of verifying the discriminant function of FIG.

The discriminant function generated in the derivation process of the discriminant model of FIGS. 8 to 11 can be expressed by Equation 1 below. As shown in Equation (1) below, the discriminant function includes the weighting value of the degree to which plural regions of the subject's brain contribute to sexual excitement.

In the step S150, a discrimination function can be generated by combining the activity level of a plurality of regions of the brain with the activity region generated by sexual arousal, and the generated discrimination model is used to determine whether the subject is sexually addicted Can be used.

<How to identify sex addicts using discriminant model>

Hereinafter, a method for discriminating sexually addicted persons through the discriminant model generated by using standardized sexual arousal induction and functional magnetic resonance imaging to be proposed by the present invention will be described in detail.

FIG. 12 is a flowchart showing an embodiment of a process for discriminating a sex addict using the discriminant model generated by the sex addict discrimination method of the present invention.

Referring to FIG. 12, in order to induce sexual excitement of a subject, the sexual arousal inducing unit 12 performs a sexual arousal induction process on a subject (S200). Here, a stimulus image is presented to the subject during the stimulus presentation period of the sexual arousal induction process, and the stimulus image is removed during the rest period. The stimulus image presented to the subject during the stimulus presentation period is a standardized stimulus image or a neutral image independent of sexual arousal.

Next, the brain image of the subject is acquired using the functional magnetic resonance imaging apparatus 20 (S210). The image processing unit 14 can measure a signal corresponding to the oxygen concentration in blood in a plurality of regions of the subject's brain using the brain image of the subject and generate cerebral activation information data based on the measurement results have.

Next, the image processing unit 14 performs a preprocessing process on the brain image acquired by the functional MRI apparatus 20 (S220).

Then, the discriminant model derivation unit 16 extracts a region in which activation occurs in the subject's brain during the sexual arousal induction process (S230). The discriminant model derivation unit 16 compares the cerebral activation information data generated during the stimulation presentation period with the cerebral activation information data generated during the pause period and determines whether or not a predetermined threshold value or more of the plurality of regions of the subject's brain It is possible to extract the active region where the activity occurs.

Then, the discriminant model derivation unit 16 extracts the blood oxygen concentration (BOLD) value in the region of interest and the region of interest among the plurality of regions of the subject's brain (S240), and the sex addiction discrimination module 30 The discriminant model derived from the subject is applied to the subject to determine whether the subject is a sex addict (S250).

13 and 14 show an example of applying the discrimination model generated by the sex addiction method of the present invention to discrimination of sex addicts.

Referring to FIG. 13, a centroid can be obtained for each of the sex addiction group and the normal group using the discriminant function. The group centroids are the mean scores obtained from the discrimination scores of the subjects belonging to each group. Accordingly, it is possible to identify the group of the two group members.

Referring to FIG. 14, if the Z value by the discriminant function of Equation 1 is larger than 0.023, it can be determined that it belongs to the sex addiction group. If the Z value is smaller than 0.023, it can be determined that it belongs to the normal group.

For example, when the discrimination score of an arbitrary object A is 1.45, it can be judged that the object A is classified into the sex addiction group. That is, when the discriminant function applied to the subject A is measured as Z = 0.272 * 3.83 + 0.501 * 3.8 + 0.124 * (- 1.83) - 1.272 = 1.45, the subject A can be determined to be a sex addict.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) . The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers of the technical field to which the present invention belongs.

It should be understood that the above-described apparatus and method are not limited to the configuration and method of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments are selectively combined .
