This study was conducted to identify factors related to the problematic experiences of smartphone use among adolescents according to gender. The subjects of this study were 54,603 male and female adolescents. This study data was analyzed using SPSS 25.0 program. As a result of this study, the relevant factors for the problematic experiences of smartphone use among male students were academic performance, economic level, counselors, fast food consumption frequency, depression, suicidal ideation, suicide plan, happiness, subjective body image, stress, and smartphone usage time. Drinking and smoking were found to be significant related factors only for female students. Therefore, in order to reduce the problematic experience of smartphone use, an intervention considering the influence factors according to gender is required.

많은 사람이 스마트폰을 소유하고 어디에서나 스마트폰 사용 모습을 볼 수 있을 만큼 스마트폰의 사용이 일상화되어 가고 있다. 스마트폰 사용 중 특히 모바일게임은 스마트폰이 보급된 이후 꾸준히 성장해온 시장으로 많은 게임이 있다. 그 가운데 국내 모바일 게임 시장에서 인기가 있는 게임은 RPG(Role Playing Game)게임이다. RPG 게임은 게임의 재미를 위하여 오랜 시간 성장이 필요하고, 자동기능을 통해 게임을 즐기기보다는 성장에 주목적을 두고 게임을 하고 있다. 이에 본 논문에서는 간단한 조작만으로 게임을 즐길 수 있는 아케이드 게임을 설계하고 Unity를 사용하여 이를 구현하였다.

Smartphone addiction and internet addiction cause a serious negative social problem due to the spread of the new media which is combined with the ubiquitous function. To evaluate the degree of Internet addiction and smartphone addiction of college students in the nearby areas, K-scale of internet addiction self-diagnosis scale and S-scale of smartphone addiction self-diagnosis scale for Korean adults were applied. This study aims to develop the survey questions, which get the basic internet patterns and access the web site, and to find the hidden addicts that is not found by general K-scale and S-scale using computers and smartphones. The result shows that a method of addiction diagnosis using the tolerance degree which is calculated by smart phone's internet main activities and using time(anticipated and real time) apart from K-scale and S-scale. So hidden internet and smartphone addicts could be found through the SPSS statistical analysis program.

This study was attempted to investigate the factors that influence on problematic smartphone use and life satisfaction by smartphone usage type. A total of 25,465 people were used for the analysis and analyzed using the R (3.6.1) program. According to the data analysis, problematic smartphone use occurred in the form of leisure activity seeking and information seeking type. On the other hand, the communication type reduced problematic smartphone use. The type of smartphone use that had the greatest influence on life satisfaction was communication type The longer the smartphone use time and the higher the problematic smartphone use, the more negatively the life satisfaction.

A Smart phone is the one of the mobile devices widely used in our daily life. Moreover, various type of sensing data gathering from smart phone are effectively applicable to recognize of their users or smart phone status. Therefore, many smart phone applications based on sensor data have been actively developed. In this paper, we investigate an unexpected conditions recognition method using continuous sensing data from a single three-axis accelerometer. In addition, we implemented an application using the proposed method which provides the services notifying an abrupt changes of the smart phone conditions. By the experimented results, the application can be useful to protect the smart phone on the user's unaware conditions such as falling or a robbery case.

Due to the development of mobile devices and communication technology, cell phones have radically evolved from portable phones into smartphones and provided variety of services to a society. This paper presents Multi-user Musical Instrument application for smart phones based on band instruments such as piano, guitar, bass guitar, and drum. This application makes music playing from smartphone to integrative music data stream using the synchronization function of server. In addition, user can play it of smartphone efficiently by implementing a graphic user interface similar to real musical instruments.
