Although the need for education on sexually-transmitted-infections (STIs) for adolescents has been increasing, a limited number of adolescents receive STI education. Importantly, the exposure of youth to an STI during their adolescence period can seriously affect their genital health. Smartphones are an innovative medium that can be used to change individual behaviors, especially useful when used to educate adolescents. Therefore, we developed a customized smartphone application for Korean adolescents. The application was based on Dick and Carey's instructional system design model. In this paper, we describe the process for development of the smartphone application, and the strategies we applied to attract adolescents to use the smartphone application. Six experts verified the educational content of the application. The application's easygoing words were chosen to help adolescents understand the topic. Strategies such as cartoon clips, secret chat rooms, buttons changing color from blue to grey, questions and answers, and a repeated-learning function were used to attract Korean adolescents to the application. The smartphone application developed in this study could be used in schools, youth centers, and hospital centers to improve STI knowledge, STI prevention, and STI coping skills.

This study aims to explore how the degree of education related to information systems and the Internet literacy affect perceived security risk and how these three variables affect online transaction intention based on the Technology Acceptance Model (TAM). Since using smartphone to purchase necessary products is increasing, the study provided two different cases of using the existing Internet and smartphone to buy products. As a result of an empirical test, the degree of information system education, internet literacy, and perceived security risk had significant effects on online transaction intention mediating perceived usefulness and perceived ease of use. Unlike the expectation, the more people have education related to information systems, the more they have knowledge about hacking or cases of privacy infringement, leading to even more concerns about security, thereby believing the Internet transactions require much effort. The more the education about information system, the more we have concerns about security; therefore, perceived security risk have a positive(+) effect on perceived usefulness not a negative(-) effect. Lastly, while the degree of education related to information systems has relations with the recognition of the usefulness of the Internet transaction, the study showed that there are no relations of recognizing the usefulness and the ease of use of smartphone.

The purpose of this study is to analyze relationship between community participation and smartphone usage level. The study was conducted for 100 people aged 55 or older. We conduct a task-based questionnaire to evaluate smartphone usage level. The levels of smartphone use were reclassified as 0~3 points C level, 4~7 points B level, and 8 points or more A level based on task-based survey score. For data processing, SAS 9.4 was used. As a result, a total of 97 data were included in the result analysis, and 85 smartphone users(87.6%). There was a significant correlation between smartphone usage level and community participation(r=0.22). As a result of using ANOVA, the smartphone usage level and community participation scores showed a significant difference(p=0.04). This study confirmed that there is a difference in community participation by smartphone usage level. Most elderly people showed high smartphone education demand. It is considered necessary to develop educational programs and educational tools to improve educational satisfaction and smartphone usage.

This study was to identify the main predictors of smartphone overdependece of infants perceived by mothers and to provide basic data useful for education and practice. For this, data-mining decision tree analysis was performed using SPSS program, and the fianl 410 researches were used for analysis. The results. In the case of the whole infants, the most important predictor of smartphone dependence was father's leisure activity parenting participation. For boys, their father's leisure activity was the most dependent on their smartphone dependence. However, even if father's participation in leisure activities was high, smartphone overdependence increased again when mother's overprotection and permissive attitude were high. Finally, For girls, the most influential variable on smartphone dependence was warmth and encouragement among mothers' parenting attitudes.

Purpose: This study was undertaken to identify the effects of a camp-type group counseling program based on the self-determination theory, for controlling smartphone usage amongst university students. The program consisted of smartphone overdependence, basic psychological needs, and adaptation to college life. Method: This was a quasi-experimental research with a non-equivalent control group design (pre-test and post-test design). A total of 38 freshmen (17 experimental and 21 control) participated in the study. Experimental subjects attended a two nights and three days camp, where the group counseling program included meetings for basic psychological needs (eg., autonomy, competence, and relatedness). Results: This study showed significant differences in basic psychological needs (Z=-2.91, p=.003) and adaptation to college life (Z=-3.47, p<.001). Although no significant difference was obtained in the degree of smartphone overdependence (p=.194), mean score of the experimental group pre-test and post-test changed from the level of potential risk users to general users. Conclusion: The current findings indicate that by considering the basic psychological needs and adaptation to college life, our program could be an effective intervention for controlling smartphone usage amongst college students. Therefore, we propose that a camp-type counseling program could be considered for application as group therapy for programs associated with preventing smartphone overdependence.

Manipulating a car navigation system while driving can lead to car accident due to loss of concentration. This will be more serious for elders or beginner drivers. Recently, a new Road Traffic Law in Korea prohibits drivers from watching or operating any video displaying devices. So the car navigation system came hard to use. In order to solve the issue we design and implement a novel system where a remote person can control the car navigation system on behalf of the driver. In the proposed system, we suggest to utilize the driver's smartphone for allowing sharing the Internet connection of the phone with the navigation system. The required smartphone application and the server will also be designed and implemented.
