Losev-miller's mutual exclusion technique

FIELD: medicine.

SUBSTANCE: invention refers to medicine, forensic medicine, diagnostic measurements, including in investigative practice. An interactive psychophysiological testing (PPT) involves presenting a person being tested test questions, determining, analysing the psychogenesis parameters with using the person's physical parameter sensors, indicating the results and estimating. The test questions are typed as follows: first-version questions Q1, second-version questions Q2, neutral questions N. The questions Q1 and Q2 have an alternative meaning and equal power and are characterised by an equal presentation time, a consistency of comparing the questions according to the alternative versions, a minimised subjective personal effect of the PPT test expert by sound colour and level, an unconscious emotional support on the person's question perception, as well as an identity of putting the questions to be compared, their length and a fixation of the meaningful word and/or word combination in similar segments of both questions to be compared. The test is put in accordance with a concatenation as follows X:0→C,…,C→Q11.Q21→N→ →Q21.Q22→N→…→Q1n.Q2n→N, wherein X is a person's identification index; 0 is a non-estimated zero question; C is a question relieving an expectation stress; Q1i is the first-version question, wherein i=1, 2,…, n; Q2i is the second-version question, wherein i=1, 2,…, n; N is a neutral question; n is a number of specific circumstances of the event or action; ":", "→", "." are devisors. The questions are put taking into account the staging of the tested event, including the confirmed facts or data only and excluding the expert's conjectures or versions. The results are used to state one of the two alternative versions and to estimate the respective status of the person being tested. The psychogenesis is determined and analysed with using a polygraph, while putting the questions of the two alternative versions, indicating and processing the PPT data are conducted with a computer with relevant software.

EFFECT: method provides higher information value, accuracy, reliability, objectiveness of the PPT results as compared to the previously known tests up to 90-95% with avoiding the distortion and ambivalence of the results.

The technical solution relates to the field measurements for diagnostic purposes, and in particular to methods interactive psychophysiological testing (CFT), and can be, in particular, used by specialists CFT to activate the available representations of the experience of the tested person regarding a particular event, for example, in investigative practice.

Known testing techniques [1-13] can be subdivided into three main groups: methods of test General knowledge assessment [12-13], health [8], professional fitness [3, 9-11] and others), methods [2, 5-7] special psychological testing for diagnostic purposes (e.g., psychological training of employees of internal Affairs bodies [7] or fire [9]), methods [1, 4] psychophysiological testing when sharing tests with the results of measurements of the physical parameters of the body of the tested person.

In General the disadvantages of the known methods [5-13] are the limited functionality, lack of information and low reliability (ambivalence) test results, due, in particular, specialization and/or subjective tests.

Method [4] for detection of emotions is functionally limited to speech analysis test. Method [3] for the specification of the IKI use cognitive virtual reality for training behavioral strategies of the tested person and determine the degree of competency and may not be applicable in other areas CFT.

Method [2] is quite informative, but it is limited by the specificity of the only verbal test and has poor reliability and versatility.

The way to diagnose psychological characteristics of the individual using kinesiology for patent RU2312597C1, 20.12.2007 [1] contains all the typical signs of ways to test and adopted for the prototype. Method [1] is that make the presentation of the test face of the test questions, the definition and analysis of the parameters of the psychogenesis using sensors of physical parameters of the tested person, the indication of the results of testing and judgment.

However, the method [1] is limited by the specificity of the method and kinesiology, as well as other analogs has limited comprehension. Due to the use of subjective and insufficiently flexible procedures for determining physical parameters of the tested person, the reliability of the results of the method [1] can be low, and the evaluation of the tested person can be not correct, ambivalent or distorted.

The method Losev-Popov (special name corresponds to the name of the authors of the applicants technical solutions Losev A.V., Popov A.A.) is to create an interactive way psychophysiological testing (CFT), which allows the specialist CFT efficiency is effective to enhance the existing representation of the experience of the tested person regarding a specific event by presenting him questions-incentives for two versions with mutually exclusive meaning and equal force, in accordance with a certain (specified) scheme of presentation of issues-incentives CFT.

The main technical result of the proposed method is an extension of functional capabilities CFT at raising awareness, accuracy and reliability of results. The technical result, which excludes the incorrectness, the distortion and the ambivalence of the CFT results, achieved through the synergy of bringing specialist CFT test person equal and mutually exclusive versions of the questions of the test stimuli in conjunction with the use of the polygraph. The method may be implemented by a specialist CFT at minimum the hardware: the polygraph and computer with adequate software, and objectivity, reliability and validity of the method can be used in special and complex procedures CFT, for example in investigative practice.

The technical result is achieved as follows.

Way interactive psychophysiological testing (CFT) is that make the presentation of the test face of the test questions, the definition and analysis of the parameters of the psychogenesis using sensors of physical parameters of the tested person, the indication of the test results and recommending destined for the I. A distinctive feature of the method Losev-Popov is that questions the test stimuli were designed in the form of questions three types of questions B1 according to the first version, the questions B2 in the second version, neutral questions, and the questions first and second versions B1 and B2 are mutually exclusive meaning and equal force. The CFT test design in accordance with the concatenation

X:0→C,...,C→B11.B21→H→B21.B22→H→...→B1n.B2n→H (1)

where X is the index ID of the tested person;

0 - not estimated ("zero") the issue;

With the question of relieving the stress of waiting;

B1ithe issue is the incentive for the first version (i=1, 2,...,n);

B2ithe issue is the incentive for the second version (i=1, 2,...,n);

N - neutral survey;

n is the number of the particular circumstances of the event or action;

":", "→", "." - the separators, and the results of the test is judged on the predominance of one of two mutually exclusive versions and evaluate the relevant status of the tested person. The definition and analysis of psychogenesis carried out with the use of the polygraph, and design issues-incentives two mutually exclusive versions, display and data processing CFT performed using a computer with adequate software.

In the proposed method interactive psycho-physiological testing for activation are the category of representations of the experience of the tested person based on established facts and/or information and expert evaluation of the results of CFT professionals spend CFT, for example psychology.

As questions-stimulus under test to the person presenting verbal stimuli (questions) and/or non-verbal stimuli (e.g., objects, images, sounds, smells).

The method is also characterized in that when designing test with equal force issues-incentives two mutually exclusive versions provide the following characteristics: 1) the same time of their presentation, 2) the coincidence of the reactions of the tested person after (or when) the presentation of stimuli, 3) the correct comparison stimulus mutually exclusive do not have preferences versions, 4) minimizing the subjective influence of the personality of the CFT specialist conducting the test (the timbre and volume of the voice, unconscious emotional support), on the perception of the tested person presented stimulus, 5) identity construction (selection) comparison stimulus, they are the same length and fixation of meaningful words and/or phrases in the same locations in both the compared stimuli.

In specific cases, the implementation of the method, the number n of the particular circumstances of the event or activity compared mutually exclusive versions determine, for example, time, place, object, subject, thus take into account the phasing of events, such as cooking - making - completion.

When this difference of method bookmark is included, as polygraph use the equipment for simultaneous recording of different indicators of the functioning of the body of the tested person (heart rate and blood flow, galvanic skin characteristics, indicators of respiratory and other), such as the polygraph Varlamov, and as computers are using a personal computer or a tablet computer, a laptop.

In addition, in some cases, the implementation of the method at the same time produce CFT two (or more) of the tested individuals in relation to the particular circumstances of the event or action.

The invention is illustrated in the drawing, which shows a General diagram of a method Losev-Popov interactive CFT and the following notation:

1 - the test person;

2 - specialist CFT;

3 - polygraph sensors;

4 - polygraph;

5 is a personal computer (PC).

Way interactive CFT implemented as follows.

Test person 1 specialist 2 CFT has issues-incentives test. Using sensors 3 polygraph 4 and the personal computer 5 determines the physical (physiological and functional parameters of the tested person and at the same time by presenting issues-incentives test, analyze parameters of psychogenesis test. The test results induce on the computer monitor 5 and destined to endure the e on the status of the tested person.

Questions-stimulus test design in the form of questions three types of questions B1 according to the first version, the questions B2 in the second version, neutral questions, and the questions first and second versions B1 and B2 are mutually exclusive meaning and equal strength (see example design issues below).

The CFT test design in accordance with the concatenation (I).1

According to the test results is judged on the predominance of one of two mutually exclusive versions (taken for objective reality) and evaluate the corresponding status of the tested person. The definition and analysis of psychogenesis carried out with the use of the polygraph, and design issues-incentives two mutually exclusive versions, display and data processing CFT performed using a computer with adequate software.

Interactive psycho-physiological testing for activation of the available representations of the experience of the tested person based on established facts and/or information and expert evaluation of the results of CFT spend CFT specialists, such as psychologists. At the same time as questions-stimulus under test to the person presenting verbal stimuli (questions) and/or non-verbal stimuli (e.g., objects, images, sounds, smells).

When designing test with equal force issues-incentives dvuhsimovyiy versions provide the following characteristics: 1) the same time of their presentation, 2) the coincidence of the reactions of the tested person after (or when) the presentation of stimuli, 3) the correct comparison stimulus mutually exclusive do not have preferences versions, 4) minimizing the subjective influence of the personality of the CFT specialist conducting the test (the timbre and volume of the voice, unconscious emotional support), on the perception of the tested person presented stimulus, 5) identity construction

)1- see the notes at the end of the description (selection) comparison stimulus, they are the same length and fixation of meaningful words and/or phrases in the same locations in both the compared stimuli.

Neutral questions form the emotionally neutral condition of the tested person.

The number n of the particular circumstances of the event or activity compared mutually exclusive versions determine, for example, time, place, object, subject, thus take into account the phasing of events, such as cooking - making - completion" (see example).

As polygraph use the equipment for simultaneous recording of different indicators of the functioning of the body of the tested person (heart rate and blood flow, galvanic skin characteristics, indicators of respiratory and other), such as the polygraph)2Varlamov, and computer use who have a personal computer or a tablet computer, a laptop.

In some cases, the implementation of the method at the same time produce CFT two (or more) of the tested individuals in relation to the particular circumstances of the event or action.

Here is an example of design issues-incentives (investigative practice, method mutually exclusive versions in the version of the test (collusion-itself").

A requirement of the method of mutual exclusion (mm)3"collusion-itself" is the act attributes such as location (maximum approximation steps to the crime scene) and time. Design issues carried out with regard to the sequencing of events: "prepare - commit - end (hide)".

Plot: "15.12.2012 GV room grocery store, located at the address: GN-SC, on Skye, 19, murdered gr. X. by applying a knife cut wounds in the amount of 12 thin sharp object, presumably a cold steel pin type. The time of death 22.00-22.40. The murder weapon at the crime scene not found".

Suspected gr. P. 37 years old, a former security guard security company "Shield", presumably able to have access to the premises of the store.

Design issues:

1st stage (preparation): a significant question B1 on the first version of "himself": "You, without anyone, 15.12.2012, in the period from 22.00-22.40 to gr. X. went?"; significant UXO is OS B2 in the second version of "collusion": "You with someone 15.12.2012 GV period of time 22.00-22.40 to gr. X. went?".

2nd stage (performance): a significant question B1 on the first version of "himself": "You, without anyone, 15.12.2012, in the period from 22.00-22.40 in the shop gr. X. blows with a sharp object struck?";

a significant question B2 in the second version of "collusion": "You with someone 15.12.2012, in the period from 22.00-22.40 in the shop gr. X. blows with a sharp object struck?".

3rd stage (concealment):

a significant question B1 on the first version of "himself": "You, without anyone 15.12.2012 after 22.40 from a subject that strikes gr. X. somehow got rid of?";

a significant question B2 in the second version of "collusion": "You with someone 15.12.2012, after 22.40 from a subject that strikes gr. X. somehow got rid of?".

Design issues MIM "collusion-itself" may only reliably established facts or information, excluding speculation or version of the person conducting the testing.

Long practical testing method Losev-Popov in investigative practice has shown that the adoption of reliable and valid judgments about the predominance of one of two mutually exclusive versions over another is 90-95%, while the traditional use of the polygraph gives about 60% reliable results, and these results may be ambivalent)4.

SUBSTANCE: invention refers to medicine, namely to carrying out psychophysiological studies, e.g. analysing the individual's psychophysiological responses, and can be used in medical purposes, advertising industry, functional diagnostics, education science, psychology, judicial practice and criminal science. Current normal baseline physiological parameters of a person being tested are recorded by means of a polygraph. That is followed by forming a number of independent conceptual blocks of visual information to be presented to the person being tested on a demonstration monitor of an eye motion recording device to assess the subjective significance of the visual information. An eye position, motion, a path of motion and fixation lengths are recorded; zones of preferential passive concentration fixation are recorded. The derived data are analysed to select a primary gaze zone and to determine a gaze length. Visual information elements drawing much attention are determined; when presenting the visual information by means of the eye motion recording device, synchronous measurements of the physiological parameters of the person being tested are taken by using blood pressure contact sensors, photoplethysmographic measurement, galvanic skin response, upper and lower respiration pressure transducers, tremor sensors connected in turn to a sensor unit of a polygraph recording and processing the signals supplied from the sensors. The physiological parameter variations of the person being tested are assessed by comparing an excursion of their current values from the pre-recorded baseline values; the physiological parameter variations of the person being tested specific for perceiving the subjectively significant information and being simultaneous with the primary gaze moments are used to detect the visual information elements having the most emotional impact on the person being tested. Thereafter, the qualitative emotional assessment is ensured by distributing the detected visual information elements according to the pre-set parameters into a sequence with opposite coordinates in the form of verbal antonyms with using a semantic differential method.

EFFECT: method enables providing more accurate psychophysiological studies related to assessing the information perception, assessing the exposure of the visual information and its significance for the individual by recording the physiological parameters and using the semantic differential method.

SUBSTANCE: score rating of a medical history, neurological and psychiatric findings, and psychophysiological testing is carried out with assigning 0 points with no burdened medical history, focal symptoms and neurological clinical pattern of diseases, psychic diseases, unfavourable social environment observed. If observing one or two signs of mentioned above, 1 point is assigned. If more than three signs of mentioned above are observed, 2 points are assigned. A Luscher colour test is used to assess an autogenous norm, a vegetative and personal balance, a working capacity, a heteronomous or autonomous nature and a concentricity and excentricity. Emotionality, anger, joy and emotion control are measured by an emotional excitement scale. A degree of stress load is assessed by an Anderson life event scale. A simple hand-eye response is used to assess a functional level of the system, a response stability and a level of functionality. That is followed by detecting deviant trends by assigning 0, 1 or 2 points for each parameter depending on its value with all the points further summed up and no deviant trends in the behaviour diagnosed in case of 0 to 13 points collected; with a borderline case at 14-17 points; deviant trends in the behaviour at 18-26 points.

EFFECT: method enables objective assessment of the individual's behaviour by studying the neurological and psychiatric states and the psychological and psychophysiological findings.

SUBSTANCE: invention refers to medicine, namely to gastroenterology, and can be used for providing the higher clinical effectiveness in the patients suffering dyspepsia syndrome combined with overweight. The method involves measuring an anxiety level (HARS) and a depression level (HDRS) according to Hamilton rating scales, assessing nutritional status by bioimpedancemetry, a degree of manifestation of sleep disorders, measuring glucose, testing glucose tolerance, immunoreactive insulin, cholesterol, high-density lipoprotein (HDLP), triglyceride in venous blood. If the patient is observed to suffer dyslipidemia and impaired glucose tolerance or variations of immunoreactive insulin, the preparation Dibikor is administered in a dose of 500 mg a day for three months. The patient suffering dyslipidemia and both of the disorders stated above requires administering Dibikor 1000 mg a day for three months. If the patient suffers an overweight with a body weight index falling within the range of 27 to 29.9 standard units and an active cell mass (ACM) percentage of 45 to 55 per cent as shown by bioimpedancemetry, the preparation Dietressa is administered in a dose of 1 tablet 3-4 times a day for three to six months. If the patient suffers an overweight with a body weight index falling within the range of 27 to 29.9 standard units and an active cell mass (ACM) percentage of 45 to 55 per cent as shown by bioimpedancemetry, the preparation Dietressa is administered in a dose of 2 tablet 3-4 times a day for three to six months. If the patient suffers mild and moderate sleep disorders and shows an emotive type of eating behaviour combined with mild affective disorders, the anti-depressant Valdoxane in a single dose of 25 mg a day for the night for two weeks. The course of the disease is followed by the anxiety and depression levels two weeks after the beginning of the therapy, with the positive progression of the diseases, the 25mg dose of Valdoxane remains unchanged to the end of the therapeutic course for three to six months. If no progression is exhibited, the dose is to be increased to 50 mg a day, and the therapy is continued from four to eight months. If the patient suffers severe sleep disorders and shows an emotive type of eating behaviour combined with moderate affective disorders, the anti-depressant Valdoxane in a single dose of 50 mg a day for the night for two to three months.

EFFECT: in each specific case, the method enables providing faster reduction of the clinical symptoms, including body fat weight reduction and active cell mass and water normalisation, normalising circadian rhythms of the vegetative balance, as well as prolonging the remission.

SUBSTANCE: method employs a device in the form of a stand with two telescopic posts with induction sensors. A metal sphere moves on a channel at an angle of 5° and when the sphere passes the first induction sensor, an electrical signal is generated which triggers an electric stopwatch, and when the sphere passes the second induction sensor, the stopwatch stops. The second induction sensor is turned off and the test subject stops the stopwatch at the moment of seeing the sphere cross the finishing line by pressing a button. The reading of the stopwatch is the visual-motor reaction time. From 50 to 100 tests are carried out, which include recording all attempts by a test subject, including premature pressing of the button, constructing a personal bar chart for each test subject and selecting a standard criterion for evaluating and comparing the visual-motor reaction.

EFFECT: method increases accuracy and objectivity of evaluating visual-motor reaction to movement of an object in space.

SUBSTANCE: test is carried out by an application of a combined approach with simultaneous application of isometric and psychoemotional stress. Isometric stress is performed by means of two ring expanders, which a patient compresses in each hand with the maximal effort for the maximally possible time interval - usually for 2-3 minutes. In the process of performing an isometric test additional psychoemotional stress in the form of constant psychological setting of the patient to the maximal pressure of the hand expanders for the entire test is carried out. Simultaneously a registration of echocardiographic scans is performed from the apical access in a projection of a four-chamber and two-chamber section with an application of 16-segmented model in a combination with ECG AND AP registration.

EFFECT: method makes it possible to increase an accuracy and self-descriptiveness of non-invasive ultrasonic diagnostics of ischemic heart disease in clinical practice due to the creation of the powerful synergic effect from two stressing factors.

FIELD: medicine.

SUBSTANCE: method involves a patient's face exposure to full-spectrum natural or artificial light of light intensity not less than 2000 lux for 1-2 hours a day combined with or followed by an exercise load. Additionally, an eating disorder is typed and corrected using psychophysiological techniques. A caloric value of a diet is specified by reducing the patient's regular mean daily energy requirement per a percentage equal to the patient's body weight index with lipid restriction to 40-60 g/day for a period of 6 months with fasting days once every 1-2 weeks. The exercise load is performed in an anaerobic gradual regimen with no weight and resistance on muscle groups of the upper body and waist, with a power load on muscle groups of the lower body until muscular fatigue in the number of 2-3 sets with a rest. They are combined with or followed by a prolonged exercise load at least 4 times a week for 40-60 min in an aerobic regimen with 2-3 acceleration episodes of 3-5 minutes. They are combined with drug-free procedures aiming at improving the regional blood flow, improving the muscular tonus of the anterior abdominal wall and sides, the greater muscle groups of the upper body. If the patient has no insulin resistance syndrome or the sugar blood level less than or equal to 6.1 mmole/l, preparations and biologically active additives containing lipoic acid and vitamin B1 are administered. If the patient suffers from insulin resistance syndrome and/or a fasting glucose level of more than 6.1 mmole/l, the preparations of biguanidines containing metformin are prescribed. Diet mistakes require prescribing preparations of lipase inhibitors containing orlistat.

EFFECT: higher therapeutic effectiveness taking into account a degree of obesity with reducing side effects of therapy.

SUBSTANCE: rested and fatigue person being tested is presented with variable-frequency signals formed as test to be solved, a presentation rate of which is changed proportionally wto its solution rate, and a quantity is specified equal for the rested and fatigue person being tested. Response measurements of the person being tested on the presented signals; a degree of fatigue measurements variation are described by expressions Tav.f=Ttotal.f/Kcor.f, Tav.r=Ttotal.r/Kcor.r, wherein Tav.f is an average time for correct solution of one test in the fatigue state. Tav.r is an average time for correct solution of one test in the rest state, Ttotal.f is the total time for solution of the pre-set quantity of tests in the fatigue state, Ttotal.r is the total time for solution of the pre-set quantity of tests in the rest state, Kcor.f is the quantity of the correct tests in the fatigue state, Kcor.r is the quantity of the correct tests in the rest state. A sequence of the presented tests in the rest and fatigue human operator is pre-set equal; an average time for one correct test in the rest human operator (Tav.r) is determined by a limited quantity of 3-5 series of 10 tests and used as a reference for further examinations. The tests to be solved include logical and dynamic tests performed by the operator together with a machine. A time for performing each test is determined taking into account repeated solutions required to correct the result and to fulfil the accuracy requirements of the specific test. The psychological tests involve measuring the human operator's physiological parameters. If at least one of them goes beyond admissible levels, the human operator load is reduced by limiting the quantity of tests to be solved in the fatigue state. A degree of the human operator fatigue variation is assessed taking into account limiting the quantity of tests by a relative variation of an average time of the correct solution of the tests in the fatigue state, and respective analogous tests in the rest state.

EFFECT: method enables providing higher reliability ensured by increasing psychological, mental and lower visual component of the load, higher safety of the human operator in the process of examination and reducing time and material costs when implementing the method.

SUBSTANCE: invention refers to medicine. Determining an individual's blood glucose concentration is ensured by measuring high-frequency and low-frequency body region impedances successfully at pre-set intervals of time with using spaced electrodes fixed on the body. The measured high-frequency impedance provides the basis to determine a fluid volume in the body tissues between the electrodes, while the measured low-frequency impedance is used to determine an extracellular fluid volume in the body tissues between the electrodes. That is followed by deriving a metabolic component increment of the above extracellular fluid volume formed by the body energy carrier synthesis and recovery by calculating an increment of the above measured fluid volume in the body tissues between the electrodes as compared to the previous measured value, calculating a difference of the above increment of the fluid volume in the body tissues between the electrodes and the above increment of the extracellular fluid volume in the body tissues between the electrodes. A blood glucose increment is measured by standardising the above metabolic component increment of the extracellular fluid volume, while the individual's blood glucose concentration is determined by summing up the above glucose concentration increment and the blood glucose concentration derived at the previous stage of measurements. The glucose concentration at the first interval of time is determined by summing up the above blood glucose increment derived at the first interval of time and the initial glucose concentration.
