This study was an experimental qualitative study on the characteristics of fashion brand's mobile SNS. The study was focused on mobile Facebook and identified the characteristics of fashion brand's mobile SNS. In-depth interviews were conducted with 10 people in the 20s, who have used fashion brand's mobile Facebook application and currently live in Seoul or Gyeonggi province. After analysis of the in-depth interview data, four characteristics of fashion brand's mobile SNS were identified as follows. First, it was possible to access fashion brand's mobile SNS at any time anywhere, if users needed brand-related information. In this study, this characteristic was named 'fashion accessibility'. Second, it was possible to access update-information using fashion brand's mobile SNS or get up-to-date information about the brand in real-time. In this study, this characteristic was named 'fashion recentness'. Third, it was possible to store or capture fashion brand-related images and texts. In this study, this characteristic was named 'ease of storage of fashion data'. Fourth, fashion brand's mobile SNS was useful in various ways to fashion consumers, so this characteristic was named 'fashion usefulness' in this study. The study extracted 10 sub-characteristics of the characteristics of fashion brand's mobile SNS based on the results of a qualitative study. This study has significant value which suggests directions for future research. Also, this paper is expected to provide managerial implications to fashion companies that need to develop mobile SNS marketing strategies.

Given the prevalence of mobile social network services (SNS) such as Facebook and Kakaotalk, it has become important to understand user's continuance behavior in a mobile SNS environment. Although trust and privacy concerns play a key role in SNS users' decision-making processes, most studies on SNS have shed little light on the effects of trust and privacy concerns on SNS continuance intention. In this regard, this paper developed an integrated model to deeply understand the key antecedents of user's continuance intention to use mobile SNS by incorporating trust and privacy concerns into extended expectation-confirmation model. The proposed research model was tested by using survey data collected from 170 users who have experience with Kakaotalk. The findings of this study found that the proposed theoretical framework provides a statistically significant explanation of the variance in continuance intention of mobile SNS. The analysis results indicate that trust serves as the salient antecedent of continuance intention to use mobile SNS. However, it was found that privacy concerns negatively influence trust, whereas it is not significantly related to continuance intention of mobile SNS. The theoretical and practical implications of the findings were described.

Recently, mobile SNS traffic has increased tremendously due to the deployment of smart devices such as smart phones and smart tablets. In this paper, mobile integrated SNS gateway is proposed to cope with massive SNS traffic. Most of mobile SNS applications update the information with individual connection to the corresponding servers. The proposed gateway integrates these applications. It is for reducing SNS traffic caused by continuous data request and improving the mobile communication performance. The key elements of the mobile integrated SNS gateway are the synchronization, cache and integrated certification. The proposed protocol and gateway system have implemented on the testbed which deployed on the real network to evaluate the performance of the proposed gateway. Finally, we present the caching performance of gateway system implementation.

According to the results of the analysis, five characteristics of SNS brand personality factors such as 'sincerity', 'enthusiasm', 'charm', 'practical', and 'community' were derived. Among these, 'sincerity', 'enthusiastic', and 'community' brand attributes have a positive effect on most of mobile native advertising attributes, but 'practical' brand characteristics negatively. The attractiveness of the brand was not related to the mobile native advertisement.

The purpose of this study was to investigate adolescents' individual and microsystem variables including relationships with parents and friends affecting adolescents' experiences of mobile social networking site (SNS) cyberbullying based on the human ecological perspective. Data came from 344 middle school students who lived with both their parents in the Seoul and Gyunggi areas. A multiple regression analysis showed that adolescents' characteristics, relationships with parents, and friends were associated with their experiences of mobile SNS cyberbullying. These findings suggest that good relationships with parents could be protective factors for adolescents to reduce mobile SNS cyberbullying. However, adolescents' characteristics including aggression, depression, and delinquent peers were positively associated with adolescents' experiences of mobile SNS cyberbullying. This study highlights that various environments are closely related to adolescent development.

The mobile SNS is a promising e-service platform of the future. However, measuring its service quality is a challenge. An appropriate model for measuring service quality is required. This paper proposes e-service quality models for analyzing mobile SNS platform quality, based on previous service quality researches. An empirical study is performed on the proposed models. The results show that constructs of existing e-service models such as responsiveness and assurance do not fit the mobile SNS platform, and that loyalty and value are better measures for mobile service quality.
