Mobile web browsing services that bring the full PC browsing experience to customer's mobile handset have been emerged. This study is to investigate the intention to use mobile web browsing based on Technology Acceptance Model(TAM) which has been widely used to explain and predict the IT acceptance and incorporated with self-efficacy which was identified as an important determinant of user's new technology adoption in recent literature on technology acceptance. Specifically, from a theoretical perspective, this study not only clarifies mobile self-efficacy, but also develops an instrument to measure the concept of mobile self-efficacy. The results indicate that both computer self-efficacy and mobile self-efficacy directly influence perceived ease of use, and that perceived ease of use enhance perceived usefulness. And the findings indicate that perceived ease of use and usefulness have direct effects on attitude and then it is positively associated with intention to use mobile web browsing. Therefore, the findings imply that mobile self-efficacy can be employed as an important variable in examining user's intention for various mobile services to come in future.■ keyword :|Mobile Web Browsing|Technology Acceptance Model|Self-efficacy|Mobile Self-efficacy|

Abstract. With continuing security concerns for airport operations, the protection of internal operational protocols of an international airport has become more critical than ever before. Therefore, the Information Security System (ISS) was developed for Incheon International Airport which can protect the critical information related to airport operations. The developed ISS includes a document access control server/client agent, a user access control service linker, and an operational log file database. The ISS was developed in consideration of information life cycle of airport workflow. As a result, it can securely protect the computer system at Incheon International Airport by (1) performing realtime encoding of the users who accessed the protected files and folders, (2) limiting the user's capability to edit the protected documents, (3) tracking transmitted files to the outside companies, (4) blocking the user's access to portable storage devices, and (5) inserting security water marks on the printed outputs. With the implementation of the ISS, the real-time information system audit environment has been securely established at the Incheon International Airport Corporation.
