Inside the vehicle, temperature and humidity are suddenly changed. Accordingly, HVAC System's temperature control is very complicated. But, clarifying the relationship between temperature and humidity can reduce the control parameters. Therefore, this paper describes the relationship between temperature and humidity in the vehicle and presents a problem solving method in terms of control technologyThe vehicle sensor monitors the factors required for vehicle control and plays a role in enabling optimal control from the obtained information. Of these sensors, the driving environment of the driver is determined by the temperature and humidity inside the vehicle, and the characteristics of the vehicle suddenly change rapidly. Accordingly, HVAC System's temperature control is very complicated. But, clarifying the relationship between temperature and humidity can reduce the control parameters. Therefore, this paper describes the relationship between the temperature and humidity in the vehicle, and presents a method for controlling the temperature and humidity in the vehicle as an example.

This study was attempted to identify the convergence factors that affected the gambling abstinence self-efficacy among college students using gambling. The participants were 134 students with gambling experience at two universities in C city and G city. The results of this study are as follows. Stress(r=-.314, p<.001) and gambling change motivation(r=.272, p=.001) showed a significant correlation with gambling abstinence self-efficacy in correlation analysis. The greatest influence on gambling abstinence self-efficacy in multiple regression analysis was identified in order of stress(${\beta}=-.29$, p<.001), gambling change motivation (${\beta}=.25$, p=.003). The results of this study suggest that a gambling prevention education program which can manage stress and strengthen the gambling change motivation of college students using gambling is needed to improve the gambling abstinence self-efficacy.

This paper describes a time-series data prediction based on artificial neural networks (ANN). In this study, a batch based ANN model and a stochastic ANN model have been implemented using TensorFlow libraries. Each model are evaluated by comparing training and testing errors that are measured through experiment. To train and test each model, tax dataset was used that are collected from the government website of indiana state budget agency in USA from 2001 to 2018. The dataset includes tax incomes of individual, product sales, company, and total tax incomes. The experimental results show that batch model reveals better performance than stochastic model. Using the batch scheme, we have conducted a prediction experiment. In the experiment, total taxes are predicted during next seven months, and compared with actual collected total taxes. The results shows that predicted data are almost same with the actual data.
