The objective of this study is to investigate the determinants of the intention of continued Instagram usage. For this study, we used a self-administered survey questionnaire in which all of the scales were adapted from the previous literature. In this paper, we introduce a research model that consists of three antecedents (perceived usefulness, perceived playfulness, and customer satisfaction) that were thought to cause the intention of continued Instagram usage. The data were collected from 150 Instagram users. In order to validate the proposed research model, we used the SmartPLS 2.0. We used a two-step approach, recommended by Anderson and Gerbing(1988), that comprises a measurement model and structural model. The results showed that two antecedent factors (perceived usefulness and perceived playfulness) had a significant impact on customer satisfaction, which then causes the intention of continued usage. This study highlights the importance of the moderating effect of gender. Based on the results, this study proposes useful implications for Instagram stakeholders.

In 2005, Korean government created the Internet Personal Identification Number (i-PIN) for a new online personal identification system to protect citizens' personal information against criminal abuse. However, i-PINs have not been widely in use over a decade. Although many people joined the i-PIN service, its actual use rate has been low. This study intends to identify the factors necessary to boost the continuous use of i-PINs. It was shown that government support and perceived security had a positive effect on the perceived ease of use and perceived usefulness of the i-PIN, respectively. Perceived security also directly affected the continuous use intention of the i-PIN. The perceived ease of use significantly affected the perceived usefulness, but it did not affect the intention to continuously use the i-PIN. The factor that had the most significant influence on the continuous use intention of the i-PIN was perceived usefulness. To increase the i-PIN use rate, Korean government must reduce users' anxiety through strict security functions, and must attempt to help people use the i-PIN easily.
