This study analyzed the impact of smartphone usage on walking speed during walking on two pedestrian walkways in Daejeon Metropolitan City. For the analysis, the video data about the actual use of smartphone was acquired and the walking speed was calculated based on the walking density of the pedestrian Level Of Service(LOS) presented in the Road Capacity Manual. Multiple regression analysis and decision tree using machine learning were used to analyze the impact of smartphone usage on walking speed, and as the explanatory variables, gender, disable smartphone, use of smartphone using auditory function, use of smartphone using visual function, LOS A, LOS B, LOS C were adopted. The result showed that LOS C had the highest impact on walking speed change and the women's group using their visual function was founded to have the slowest walking speed in LOS C. In particular, the author found that walking speed significantly decreased in the case of use of visual function rather than listening to music or the hearing on the phone.

Despite the ever-increasing smartphone addiction of adolescents and a variety of consequent problems not much research has been conducted on the issue. It is time to prepare a set of countermeasures to protect them from the addiction. The central purpose of the current paper is to identify how use motives, self-control and social withdrawal affect their smartphone addiction. It was found (i) that the motives of information acquisition, social relationship, amusement and use of leisure time exert significant influence on smartphone addiction, (ii) that less self-control and greater impulsiveness result in greater addiction, and (iii) that social withdrawal of users also have significant effect on smartphone addiction. Such findings are expected to provide base data for any attempt to develop countermeasures against addiction. It is desirable that we had better check the play activities of adolescents and develop self-control programs to help them alleviate impulsiveness than simply impose strict restrictions on the use of smartphones.

The purpose of this study was to investigate the standardization of daily average smartphone use time among adolescents. The data were analyzed using the data from Korea youth risk behavior web-based survey of 2017, and the total number of students analyzed was 54,603. Frequency analysis, independent t test, Pearson correlation analysis, and one-way ANOVA were used for statistical analysis. As a result, the correlation coefficient between smartphone use time, age, and grade was very low (r =.025~.039). There was no significant difference in the usage of smartphone between middle and high school students(p>.05). Time of smartphone use was significantly higher in middle school students as the grade increased(p<.05). In high school students, second-year students had significantly more smartphone usage than first and third grade students(p<.05). The researchers described 54603 adolescents' average(minute) daily smartphone usage about sex(male, female), period of use(weekday, weekend), school(middle school, high school), and grade(first, second, third) as a 7th quartile. We suggest that the standard value of smartphone use time can be used as a basis for the physical and mental health management in adolescents. It is necessary to present a standard value that can prove the future overuse of smartphone.

An application that has a simple user interface not only motivates a user to continue using the application, but also enables the user to develop their mental model for the application - the like of which is a product of their interaction with the application. In the information systems literature, little empirical research has been undertaken on the effects of the mental model and motivation on smartphone users' behavioral beliefs. Therefore, the aim of this study is to suggest a research model that can examine the following: 1) the effects that the mental model has not only on smartphone users' behavioral beliefs (that is, perceived usefulness and ease of use of an application) but also on their behavioral intention to use an application and 2) the effects that smartphone users' intrinsic motivation has on their behavioral beliefs through an expansion of the mental model. A survey is conducted, and structural equation modeling is then used to analyze the survey data. The results, through consideration of variables such as intrinsic motivation, perceived usefulness, perceived ease of use, and user satisfaction, indicate that the mental model has an indirect effect on a user's intention to use an application.

We aimed to construct and test a structural equation model to analyze the convergence effect of utilizing smartphone technology for Therapeutic Lifestyle Change(TLC) among people with mental illness. A survey using a structured self-questionnaire was conducted from 549 male and 357 female subjects. The data was analyzed by SPSS 23.0 and AMOS 21.0. The model fit for the modified hypothetical model was shown: Q(${\chi}^2/df$)=3.241, AGFI=0.968, CFI=0.970, RMSEA=0.050(95% CI=0.035, 0.065), SRMR=0.048. In modified model from hypothetical model, the opinions about smartphone use affect the willingness to use smartphone applications. And the willingness to use smartphone applications affect dietary and living habits. The result of this study suggests that a convergent study using various delivery systems such as smartphone technology is necessary to implement TLC, which can facilitate the prevention of the metabolic syndrome among people with schizophrenia.
