Purpose: In 2015, South Korea had the highest global smartphone penetration (88%). However, smartphone addiction can seriously disrupt daily life and have a major negative impact on academic achievement. Methods: A structured questionnaire was completed by 250 nursing students for this descriptive study. Results: Students who were older, more satisfied with their major, exercised, and used their smartphone for less than 30 minutes before sleeping had higher learning engagement than those who were younger, less satisfied, did not exercise and used their smartphone for more than three hours. Quality of sleep and smartphone addiction were negatively correlated as was quality of sleep and daytime sleepiness. Interestingly, sleep pattern did not impact learning engagement directly. Conclusion: Smartphone usage influences learning engagement of nursing students rather than their sleeping patterns, which suggests a need to develop self-disciplining strategies for smartphone use to enhance learning engagement.

This study investigated the antecedents and the performance impact of two types of Smartphone functions (communication vs. computing functions) in organizational environment and the moderating impact of Smartphone users' organizational roles. More specifically, identifying two distinct types of Smartphone functions such as communication functions and computing functions (including informational, social network, and resource management functions), we investigated the impact of three antecedents (Smartphone dependency, task mobility, and perceived critical mass) on the use of the two Smartphone functions and how organizational workers' perceived performance gains differ by using these two different Smartphone functions for their workplace activities. We tested our hypotheses with survey data collected from 176 organizational workers. Our findings suggest that Smartphone dependency, task mobility and perceived critical mass of Smartphone use are significantly associated with the use of the two different functions, and that the use of computing functions is more strongly associated with perceived performance gain than the use of communication functions. We also found that managerial roles played by individual workers differently moderate the impact of Smartphone use on perceived performance gain. The present findings enable researchers and practitioners to better understand the impact of Smartphone use in workplaces.

A smartphone is a mobile phone that offers more advanced computing ability and connectivity than a contemporary basic feature phone. Unlike feature phone, a smartphone allows the user to install and run more advanced applications based on a specific platform. Smartphones run complete operating system software providing a platform for application developers. A smartphone will become the default computing method for many point activities in the not-too-distant future, such as e-mail, online shopping, gaming, and even video entertainment. For smartphone that contains sensitive information and access the Internet, security is a major issue. In the 1980s, security issues were hardly noticed; however, security is a major issue for users today, which includes smart phones. Because security is much more difficult to address once deployment and implementation are underway, it should be considered from the beginning. Recently our government recognized the importance of smartphone security and published several safety tips for using the smartphone. However, theses tips are user-oriented measures. Maintaining the security of a smartphone involves the active participation of the user. Although it is a important users understand and take full advantage of the facilities afforded by smarphone, it is more important developers distribute the secure smartphone application through the market. In this paper we describe some scenarios in which user is invaded his/her privacy by smartphone stolen, lost, misplaced or infected with virus. Then we suggest the security considerations for securing smartphone applications in respect with developers. We also suggest the methods applying domestic encryption algorithms such as SEED, HIGHT and ARIA in developing secure applications. This suggested security considerations may be used by developers as well as users (especially organizations) interested in enhancing security to related security incidents for current and future use of smartphones.
