The Addiction problems have been became a social problem; the social efforts continue to solve these problems. One of those efforts, we need to establish a mathematical modeling for an addictive model to perform analysis of behavior by using this modeling. We need to process the research that can be judged before and after addictive status with result of the behavior analysis. We have to process an observation of transition from before to after addictive status. According to those necessary, this paper proposed the physical exercise model that is composed by novel second order system, which consisted of Spring-Damper-Mass system with equivalence in order to evolve an addictive equation for physical exercise. This paper also is analyzed by the behaviors for those the addictive equation of physical exercise.

Addiction can be largely divided into two categories. One is called medium addiction in which medium itself causes an addiction. Another is called cause addiction that brings addiction through combination of sensitive self and latent personal action. The medium addiction involves addiction phenomena directly caused by illegal drugs, alcohol and various other chemicals. The cause addiction is dependent on personal sensitivities as a sensitive problem of personal and includes cyber addictions such as shopping, work, game, internet, TV, and gambling. In this paper we propose two-dimensional addiction model that are equivalent to using an R-L-C series circuit of Electrical circuit and a Spring-Damper-mass of mechanical system. We also organize a Duffing equation that is added a nonlinear term in the proposed two-dimensional addiction model. We represent periodic motion and chaotic motion as time series and phase portrait according to parameter's variation. We confirm that among parameters chaotic motion had addicted state and periodic motion caused by change in control coefficient had pre-addiction state.

The aim of this study was to examine the relationship between the physical exercise needs, exercise commitment and exercise addiction based on the degree of participation by health club members and furthermore to verify the suitability of the structural model of variables based on these relationships. The subjects for this study include adults aged over 20 years old who exercised for over 3 months in 2014 Random sampling of data from subjects at their convenient time and place known as the convenience sampling method was used to analyze a total of 151 surveys. The collected data was statistically processed using SPSS 18.0. The results of the analysis reached the following conclusions. Firstly, depending on the degree of participation of the health club member, a significant variation was perceived between physical exercise needs, exercise commitment and addiction. Secondly, physical exercise needs had a significant influence on exercise commitment. Thirdly, physical exercise needs had a significant influence on exercise addiction.

The purpose of this study was to analyze the difference between Exercise addiction and Affect, and addiction-related potential was investigated. In addition, exercise addiction prevention and positive exercise was to identify. The participants of the study included 312 tennis club member who were more than 20 years old and lived in seoul city. The survey was analyzed by SPSS PC+ for window (version 12.0) which is a statistical analysis program to produce the computational results of this study. Based on the survey, this study could draw such results as follows: First, exercise addiction, gender and age on partial variables were statistically significant differences. A male positive addictions, exercise desire were higher than in female. 50s in the withdrawal symptoms of the variables that showed statistically significant difference participation, and period, frequency, time of exercise addiction showed that in withdrawal symptoms, positive addictions domain in a statistically meaningful differences. Second, social demographic domain in the presence of gender showed significant correlation exercise desire were and exercise participation time in the positive addictions showed significant correlation. Participation frequency and the time involved in retaining all the positive affect and negative affect have found a high correlation. Third, the influence of relation between exercise addiction and affect of tennis participants, exercise desire, positive addiction, showed in a statistically positive affect and negative affect meaningful influence on it.

The purpose of this study was to examine the differences and the relationship between basic psychological needs and exercise addiction and to identify effects of To do this, the data were collected using the self-evaluating questionnaires on the exercise addiction, the of basic psychological needs, and the subjective were distributed to 305 participants in general exercise enthusiast for all, and the collected data. This study used the SPSS Statistics 18.0 program to process data. Exploratory factor analysis was performed for validity and Cronbach's α was performed for reliability. In addition, Frequency Analysis was carried out to analyze the demographic characteristics and Pearson's Correlation Analysis, independent t-test, one-way ANOVA, correlation analysis, multiple regression analysis Analysis were performed to verify the correlations and differences among variables. The significance level in this research was set at=.05 and the followings α are derived outcomes. The following is the comprehensive finding of the effect of general exercise enthusiast exercise addiction through basic psychological needs. First, there was no significant difference in basic psychological need and Exercise Addiction of general characteristics, but participation in 6 days was the highest in exercise amount per week. Second, Basic Psychological Need(autonomy, competition, relatedness) showed a high difference in Exercise Addiction(withdrawal symptoms, exercise need, emotional attachment). Third, correlation analysis between all variables showed statistically significant difference. Fourth, Basic Psychological Need(autonomy, competition) was found to have a high effect on Exercise Addiction(withdrawal symptoms, exercise need, emotional attachment).

The conclusion of this research was as follows: First, Participation motivation had a effect on enjoyment factor in dance sports club participants. Second, Participation motivation had a effect on exercise dependence in dance sports club participants. Third. Enjoyment factor had a effect on exercise dependence in dance sports club participants. It was concluded that participation motivation would be beneficial for enjoyment factor and exercise dependence in dance sports club participants.

Based on sports known to reduce adolescents' smartphone addiction, this study aims to identify the structural causal relationship between sport commitment and smartphone addiction. First of all, based on prior studies, it was intended to show that adolescents' sport commitment is effective in reducing smartphone addiction through social support and ego-resilience, and that such causal relationships vary significantly depending on gender. To this end, a survey of 605 middle and high school students was conducted, and the structural relationship between the four established latent variables was analyzed by analyzing the structural equation model using the SPSS 25.0 and AMOS 23.0 programs. According to the analysis, adolescents' sport commitment was found to have an adverse effect on smartphone addiction, and social support and ego-resilience in the relationship between the two variables were found to have a mediated effect. In addition, these results showed significant differences in gender. This study expanded the field of smartphone addiction and sports convergence study by revealing the relationship between sport commitment as psychological recognition variable and addiction Unlike previous studies using a participation time, duration, and intensity, and suggested that structural relationships with personal characteristic variables and gender-specific approaches are important. Through this, it is meaningful that it provided basic data for in-depth convergence study in the smartphone addiction and development of gender-specific programs.

This study examined the relationship among self-control, physical activity, Internet addiction, cyber ethnics, and cyber delinquency. The data from a total of 388 adolescent girls was analyzed by structural equation modeling using the AMOS 20.0 statistics program. First, the level of physical activity affects Internet addiction mediated by self-control. Second, self-control affects Internet addiction and cyber ethnics directly and has an influence on the cyber delinquency mediated by Internet addiction.
