Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for measuring body change according to the presentation of a stimulus for classification of sex crimes,

The present invention relates to a system and a method for measuring a body change according to a stimulus presentation, and more particularly, to a body change measuring system for measuring a sex crime in a body of a subject, We measured the response and physiological changes of the autonomic nervous system of the subjects according to the visual stimuli and auditory stimuli in which the photographs were presented, and provided data to judge whether the subject was a child sexual attachment or not, System and method.

In recent years, social insecurity has been increasing due to the increase in sex crimes and the furor of crime. In this regard, the national sex crime is defined as the crime of the 4th generation crime, and efforts are being made to reduce it. In the case of sex crimes, it is known that the risk of recidivism is higher than other crimes. It is important to select and manage people who are at high risk for sex offenders, because some criminals with high risk of sexual crime are repeated.

There are various risk factors for sexual crimes, but among them sexual crime personality factors such as child sexuality tend to be strong risk factors for replay. Child sexual assault has a high risk of recidivism, and since the victim is a child, the effects of crime on victims are more serious than adult sexual assault crimes, and active management and intervention is needed.

In order to effectively manage and intervene in persons with child sexual anxiety, one must first accurately classify those who have this tendency among sex offenders. Currently, sex crime classification methods in Korea are usually conducted by specialists through their statements or criminal history. However, in this method, it is difficult to classify them effectively through professional diagnosis only if they make a false statement about their past history or committed a homicide in the past but have not yet discovered a crime. Therefore, there is a need for other methods that can classify sex offenses more effectively and accurately.

For reference, HRV (Heart Rate Variability) is the periodic change in heart rate over time as "heart rate variability".

The autonomic nervous system (ANS) is divided into sympathetic and parasympathetic nerves, and HRV is used to identify the parasympathetic nervous system during exercise. The time difference between heartbeat and heartbeat is measured to determine the difference The average is calculated, and it can be accurately determined whether it is in a mental or physical stress situation.

Electrocardiogram (ECG) signal is a record of heart rate, rhythm, and cardiac conduction of heart contraction and relaxation activity.

The heart rate variability (HRV), which is the change in the time interval between heartbeats (IBI), is measured from the ECG signal. The lower HRV represents the relaxed state and the increased HRV represents the state of mental stress or frustration .
