The present study aims to evaluate the self-determined motivational features of smartphone addiction management apps. This study analyzed whether smartphone addiction management apps have features to support adolescent users' basic needs, that is, autonomy, competence, and relatedness. 26 apps were analyzed. Among them, 8 apps were parental management apps installed on a parent's phone and a child's phone, and 18 apps were self-management apps installed on a child's phone. According to a content analysis, only 3 of 26 apps addressed all three basic needs. Overall, the functions to support users' competence and relatedness were rarely found. Particularly, parental management apps had a high level of controlingness. The results suggest that the addiction management apps have limitations in stimulating adolescent users' self-determined motivation to manage their phone use.

As smartphones permeate the consumer lifestyle, branded application and mobile shopping have also received increased attention as an important marketing channel. This study identifies the general information about the use of smartphones, attitudes toward fashion applications, and mobile shopping intentions for smartphone users. Focus group interviews were conducted and 22 interviewees participated. The age of the participants ranged from 21 to 45 years old (55% were females). When examining the motivation to adopt a smartphone, respondents presented the comparable characteristics of early adopters and late adopters according to the time of adoption. Most respondents over the age of 30 showed some troubles to use a smartphone; however, participants in their 20s tended to enjoy exploring the new technology. More than half of respondents were aware of fashion applications, but were dissatisfied with fashion apps and used them infrequently. Respondents pointed out that fashion related apps were not too practical because they were not updated regularly, provided only limited information, and focused on brand promotions. In order to increase the intention to adopt mobile shopping, the price and payment security system needs to be considered. This was an exploratory study to identify the possibility of fashion branded apps as a major distribution channel. The findings of this study provide fundamental information to formulate marketing strategies for fashion businesses that have developed fashion apps.

Purpose: The purpose of this study was to examine the level of agreement between smartphone apps and self-reported physical activity questionnaires. Methods: Quantitative methods were used to assess the correlation and agreement between the number of steps counted by a smartphone app and the amount of walking reported in a survey. A total of 29 adults who used smartphones were recruited from a university, and their step counts from their smartphone pedometers and responses to the international physical activity questionnaire (IPAQ) were collected over a 10-week period. Results: An analysis of 170 data pairs with Spearman's rho correlation and a Bland-Altman plot revealed a positive correlation between step counts from the smartphone app and walking activity from the IPAQ. The Bland-Altman plot also demonstrated the agreement to be improved among female participants. Conclusion: In assessing walking activity, smartphone pedometer apps showed good correlation with the IPAQ and improved agreement with the IPAQ among women. Therefore, it is suggested that the participants' gender and activity intensity, as well as the accuracy of measurement tools, should be considered in an evaluation of the delivery of physical activity promotion programs through smartphone apps.

The purpose of this study is to analyze the patterns of unconsciousness smartphone use by using an app and a self-administered survey on smartphone addiction comparatively and examine differences between recognition and behavior about actual smartphone use and examine how smartphone addiction influences learning. With an app installed in smartphones, this author collected and analyzed data about users' unconsciousness using patterns for a month. According to the results, there were significant differences found in users' recognition and actual time for use and also frequency of turning on the display. Also, 22% of the subjects used their smartphone over 8 hours a day, and 76% more than 5 hours. Over 95% turned on the display more than 100 times a day, and in extreme cases, they did more than 300 times. In the meantime, users not only in the smartphone addiction high risk group and the potential risk group but also in the general user group are found to use their smartphone too long and too much and frequently turn on the display. The apps that the general user group is mainly using are entertaining apps, and their school records are rather good, so excessive use does not always lead to addiction or learning disorder. Therefore, if we develop more diverse contents for learning and provide digital literacy education, smartphone use will bring more positive effects instead. In follow-up research, the app should be corrected to collect more accurate information, and as variables in personal areas, this researcher will also measure depression, anxiety, stress, self-esteem, and emotional control, and so on to see how they are associated with smartphone use.

In the mobile-first era, plenty of mobile apps have been created so that the number of apps owned in a smartphone have been increasing as well. However, users spend most of time with only a few apps and the rest of apps are just kept in their smartphones for future usage. Thus, in order to help users find the apps quickly it is important to study how users arrange apps in a mobile phone screen and find an app. In the literature, we extracted 5 user types to organize mobile apps. We further conducted user survey with 30 subjects and finalized major 3 user types categorized by relatedness(A), aesthetic(B), and external concepts(C). We found that most of subjects took less than 2 minutes when finding frequently-used-apps. However we identified difference in times taken to find a barely-used-apps across three user types; while A type users turns out to be the most effective in finding barely-used-apps, the B type uses tend to be the least effective among three types. For the A type users, an app's name is more important than an icon image because they tend to guess the functionality from the name of the app. The B type users use the color of app icon to find the app in the smartphone. For the C type users who tend to remain the original position of an app when first downloading it in the smartphone, the visibility of an app icon is important to catch users' eyes while they scan a page. The results of this study is expected to be useful for UX designers who improve the usability of app icon usage considering the user types.
