Maintaining online services of high quality has become a crucial factor for brokerages to gain competitive advantages. Because of the attributes of the product uniformity of online trading, online brokerages have grown significantly with IT development, since the early 2000s. Now, as the online trading business gets mature, the profitability of the IT investment and the quality of IT-based services became questioned. This study examines the issues of IT investment and its contribution by analyzing the relationship between the quality of online service and IT investment. In addition, it also investigates the relationship of the quality of online services and profitability of brokerage. Our results show that IT investment draws cubic-style, curvilinear relationship with the service quality of online trading and only high quality services can lead to the increase of profitability.

Cloud computing is cost-effective in terms of system configuration and maintenance and does not require special IT skills for management. Also, cloud computing provides an access control setting where SSO is adopted to secure user convenience and availability. As the SSO user authentication structure of cloud computing is exposed to quite a few external security threats in wire/wireless network integrated service environment, researchers explore technologies drawing on distributed SSO agents. Yet, although the cloud computing access control using the distributed SSO agents enhances security, it impacts on the availability of services. That is, if any single agent responsible for providing the authentication information fails to offer normal services, the cloud computing services become unavailable. To rectify the environment compromising the availability of cloud computing services, and to protect resources, the current paper proposes a security policy that controls the authority to access the resources for cloud computing services by applying the authentication policy of user authentication agents. The proposed system with its policy of the authority to access the resources ensures seamless and secure cloud computing services for users.

This research intends to explore two questions: 1) how the service qualities of trade exhibitions affect the participant's satisfaction, and 2) how participation motivation moderates the relationship's between the service quality and satisfaction. For this purpose, the service qualities were measured with respect to three components: 1) core services, 2) physical environments, and 3) personal services of trade exhibitions. The results showed that the core services had largest impact on the participant's satisfaction among three components. The influence of the personal services was next strong, and the impact of the physical environment was weakest. Participation motivation was shown to moderate the effects of core services and personal services on satisfaction, but its moderating impact on the relationship between physical environments and satisfaction was not observed.

The concept of "ubiquitous" has become the top issue of the 21st century communications field within the past years. u-City has become the new city paradigm with the convergence of city planning and ubiquitous communication technologies and services. Starting from 2004, KT has collaborated with the Korean government to develop comfortable, convenient, pleasant, safe, and healthy IT technology based u-City focusing on; balanced development, value creation, and improved standard of living within the region. Presently the term, "hazard mitigation services" lacks a clear definition due to its varying applications by different local agencies and has caused confusion. Therefore, this report will clarify and define u-City hazard mitigation services currently proposed to the local agencies as well as services currently in effect. Additionally, the report will introduce hazard mitigation service models feasible by KT.
