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 purpose of this study is to classify the degree of change of job discrimination of the disabled according to time and to identify factors affecting life satisfaction according to each type. For this study, data from the 3rd to 8th year of the employment panel for the disabled were used and 1,227 data were used. The longitudinal profile of the disabled person's discrimination was classified through latent profile growth analysis(LPGA), and then influential factors were verified through binomial logistic regression analysis. First, the types of change of the job discrimination of the disabled were represented as the decrease group and the increase group. The factors influencing the job discrimination were the degree of disability, chronic diseases, gross income, and life satisfaction. Second, the factors of predicting the life satisfaction according to the types of job discrimination of the disabled are as follows: job discrimination, decrease and increase group have higher life satisfaction as the self - esteem and socioeconomic status are higher. Based on these results, this study suggested the implications of this study to cope with the discrimination of the workplace with the disabled.

This study was conducted to propose anti-stigma strategies by verifying the social stigma on behavioral addiction under the premise that social stigma is a main obstacle to the treatment of addiction. A research model was constructed by applying the attribution affection theory and the modified attribution affection theory, which are very useful for explaining emotional and behavioral responses to the persons with mental illness. In other words, when attributing the causes of behavioral addiction to the personally controllable things such as personality, will and lifestyle, social distance can be increased by the mediate of anger. However, when attributing the causes of behavioral addiction to biological factors that can not be controlled by an individual, there can exist two pathway, one is the arising of helping behaviors by the mediate of sympathy (the attribution affection theory), and the other is the aggravation in the social distance due to rising fear (the modified attribution affection theory). In order to verify the research model, 383 adult subjects mainly in South Gyeongsang Province were randomly presented with the vignettes of gambling addiction and internet game addiction, and asked about the causes of the problems and their emotional, prejudicial, and behavioral responses to them. As a result, all pathway had statistically significant predictive effect. Therefore, in the case of attributing to personal causes, social distance increased by the mediate of anger. In the case of attributing to biological causes, both pathway had significant predictive effect, but the indirect effect of the pathway predictive of the helping behavior by the mediate of sympathy was greater. Researchers suggested that anti-stigma strategies, which emphasize that behavioral addiction is a mental health problem requiring treatment, are necessary.

The purpose of this study is to examine the impact of spiritual commitment, social support and self-esteem for the deviant behaviors of middle-aged men from 40 to 59 years old. Further, this study seeks for providing basic data for designing social welfare service programs to intervene and prevent such deviant behaviors The findings of this study can be summarized as follows: The relationship among variables are as follows. First, spiritual commitment could directly affect the mid-life deviant behavior, and could cause influence indirectly through the self-esteem. Second, social support could not directly affect the mid-life deviant behavior, but could cause negative influence indirectly through the self-esteem. The significant is that this study triggered off interest in deviant behavior of middle-aged men. Especially, this study realized to us interest in spiritual commitment which has been not interested in the social work. This implicated that social support and self-esteem might effect to be deviant behavior of middle-aged men as well as deviant behavior of youth.

All measures related to the safety of the casino facilities guarantee safety of facilities that are targets of security guards, protect lives and properties, minimize risks of artificial and natural disaster and crimes. In summary, plan for responding to safety and accidents should be developed not only for the casino facilities but also for the facilities of annexed buildings, and lives and properties of customers and employees. Determine areas in the casino facilities that are prone to accidents and set around-the-clock guard in the areas or maintain surveillance with CCTV and prevent accidents through continuous patrol. These are the most basic and the most important requirements in safety. In addition, casinos which prompt gambling are causing economic and psychological treats to families. To resolve these social issues, casinos have adopted limited entrance system. To support this system, new forms of machine security systems such as video automatic recognition system of fingerprint pattern recognition system should be adopted too. In addition, security guards in casino facilities need to instill themselves with a sense of ownership as well as a strong sense of mission to do the best for customer security and to protect the company assets and employees and manage accidents that could occur without notice. Security guards should do their best to enable manage accidents that could occur without notice. Security guards should do their best to enable tourists who are on the rise due to increase in advanced country-style tourism and leisurely activities to get the utmost satisfaction from the casinos, and as a leader of private security company, establish the foundation for security based on the characteristics of security in Korea.

Bio-ethanol production research using various material has been problemed for solving problems of environment pollution caused by fossil fuels. Red-algae consists of agar, carrageenan, and porphyran. If it is treated by acid, it is able to change useful bio-mass for bio-ethanol. In this study, we found an optimal condition for bio-ethanol production from acid hydrolysate in red-algae. To produce bio-ethanol, Saccharomyces cerevisiae KCCM1129 inoculated to acid hydrolysate of Gelidium amansii. The optimal condition for Gelidium amansii hydrolysis was found to be 30 min reaction at $H_2SO_4$ concentration of 1.5% and $121^{\circ}C$. At this condition, its produced to 7.04 g/L galactose and 1.94 g/L glucose. And acetic acid concentration of 2.0% in agar produced 0.75 g/L galactose. In contrast, Pachymeniopis elliptica was treated with $H_2SO_4$concentration of 1.5%, it produced 6.38 g/L galactose. And Pachymeniopis elliptica treated with acetic acid concentration of 2% produced 0.368 g/L galactose. The optimal condition of ethanol production was found to be 96 h reaction at $H_2SO_4$concentration of 1.0% and $30^{\circ}C$, which produced 3.77 g/L ethanol.

This research was fairness in sport and power is how they form and change through historical discussion on the sport's doping and ran afoul of fairness Explored in match-fixing in relationship with power, the product of the problems of human desires. First, doping and exploration of power. The history of doping in sports, history as long as it existed before. Medication is ruler of the players can't or don't conform with authority between the pair formed a relationship, where, in accordance with the victory of a temptation for wealth and fame and vested interests and desire, is personal, Society and country ranging and widely is committed. In particular, power of expression is reflected well reflected in the sport in the Cold War era and, in those days was wrong thinking and practices are still truly understands the connection between doping and anti-doping. Second, match-fixing and exploration of power. Also in the history of sport as doping, match-fixing, always existed. Sport and fairness of match-fixing in relation to artificial sources, and well decide the outcome of which ended with sport, not an issue connected to gambling and other crimes, And that's another sport and bring about a vicious circle of even turn into a row. The reason for this match fixing in power part of the formation of capital and profits for the exact cause has developed that further threatens the fair sport. Thus, in fairness, and relations of power in sport doping and match-fixing is historically very meaningful and, further research and discussion is needed. Buried the materialistic values of sport doping and match-fixing, nothing is being tolerated and other researchers' power as the elements of the pie grow only by sport only No one can guarantee that only satisfied if we hold a bright future of sport.
