Moblie device based financial services are vulnerable to social engineering attacks because of the display screen of mobile devices. In other words, in the case of shoulder surfing, attackers can easily look over a user's shoulder and expose his/her password. To resolve this problem, a colour-based secure keyboard solution has been proposed. However, it is inconvenient for genuine users to verify their password using this method. Furthermore, password colours can be exposed because of fixed keyboard colours. Therefore, we propose a secure mobile authentication method to provide advanced functionality and strong privacy. Our authentication method is robust to social engineering attacks, especially keylogger and shoulder surfing attacks. According to the evaluation results, our method offers increased security and improved usability compared with existing methods.

In this study, two controversial Child Care Policies will be discussed based on the perspective of Economics: Accreditation of Child Care Centers and Liberation of Child Care Service Tuition. Liberation of Child Care Service Tuition is to provide parents and children with exact quality which they want at a differentiated price. Accreditation of Child Care Center is to enhance the quality of child care service by evaluating the quality of centers and grading centers into three classes. This study concludes that success or failure of the policies mostly depend on the investment capability of the government to increase the supply of child care centers. Employing these two policies requires the child care rate more than certain level and more financial investment from the government since the responsibility of providing child care services relies mostly on the government in Korea.

For many reasons, SI(Systems Integration) projects can fail. Sometimes, they can result in considerable financial losses to the organizations that undertake them. These projects are abandoned or redirected. However, the cost of project abandonment or redirection can represent a tremendous waste of organizational resources. By managing failure factors carefully, project managers can prevent projects from failing. Types of project failure can be categorized into escalation and de-escalation. Project escalation is that, as projects progress, the project scopes keep increasing. Project de-escalation is that, as projects progress, the project scopes keep decreasing. This study examine relative importance of risk factors that cause project escalation and de-escalation.

In this study, we analysed the current situation of Internet-based insurance services which can provide a non-traditional and cost effective communication channel between the customers and insurance companies. The service of Internet-based cyber-insurance extends from mere advertisement to on-line contracts through planning simulations and, furthermore, to customer monitoring. This cyber-insurance is the demand of the times and is not to be overlooked-by the Korean insurance companies which are suffering from accumulated loss and are facing severe economic depression. We performed a comparative analysis between the domestic cyber-insurance service and pioneers'. Also, we suggested future possibilities of cyber-insurance services, presenting an architecture for the construction of a cyber-insurance management module within the meta financial investment system.
