  • Since introduced in 1997, the transportation card system in Korea has been developed up to the world-top-tier technical level and gradually implemented in many other countries. Especially, the public transportations are significantly considered in terms of reducing greenhouse gas emission and environment pollution. In addition, a nation-wide transportation card system will be feasibly completed until 2013. However, for overcoming user's inconvenience, the unmanned sales/charging machines of the cards should be urgently required. In this paper, a new integrated operating system for unmanned sales/charging machines of such cards is designed and implemented by analyzing problems of the existing machines. The proposed system is hierarchically composed of multiple modules; machine initialization, work finishing, sales, charging, A/S handling, and management modules. We established and operated this machine in Seoul and Gyeonggi region. This research demonstrates that spread of the user-friendly integrated operating system improve user's convenience especially with respect to interoperability among transportation means and their areas.

  • This paper studied the impact of CIO leadership on the IS performance. The survey was developed to measure the relationship between CIO leadership style and the IS performance. The study shows that the differences in CIO leadership style along the two dimensions of goals and modes do not cause a statistically meaningful difference in business efficiency, one of the IS performance. Contrary to the existing studies that suggest a balanced leadership is effective, this study illustrates that strategic leadership and enabling leadership are more effective in the aspects of targets and manners respectively. This study does contribute to the introduction and utilization of CIO: unlike existing studies on leadership, it proposes a new approach to classifying leadership style based on the styles exhibited by CIO's flexibly from one situation to another. It will provide companies considering appointing CIO's or already using CIO's with insights into effective CIO role. It is important to provide CIOs with position and authority to exhibit their leadership flexibly.

  • The government was fully aware of the gravity of a recent massive leak of personal information of credit card users. Meanwhile, the government just took a light disciplinary action by imposing a fine, but it showed its intention to strengthen the regulations by taking the severest disciplinary action. The tightened regulations against personal information leak will be applied to the private security industry without exception to protect individual people's property and lives if such an incident occurs in that industry that deals with a wide variety of personal information such as CCTV data or privacy information all the time. The purpose of this study was to examine the state of the protection and management of personal information for service users among private security firms in an effort to suggest some reform measures. The findings of the study were as follows: First, administrators or managers who are involved with personal information protection should make a full-fledged effort to gather information. Second, counseling or related programs should be provided for small and mid-sized security firms to guarantee thorough personal information protection. Third, Korea Security Association should improve the educational system related to personal information protection to resolve problems with this education currently provided for managers and employees of these companies.

  • The sport industry has been continuing to grow in the past few decades in the U.S., and it presents significant opportunities for the practitioners to increase the number of patrons. To convert this opportunity to optimum benefits for a sport organization, one of the most significant challenges for the practitioners would be promoting sport attendance and repatronage. So far, many studies have tried to identify variables that affect the level of sports attendance. However, many of these variables are rather uncontrollable due to the nature of the sports and contingencies that are derived from many areas of uncertainties. Thus, to acquire competitive advantage and profit maximization, it would be essential for the managers to focus on understanding controllable elements. This study found that many controllable variables that influence sports attendance coincide with the servicescape elements which have been widely used in the hospitality industry since 1992. In the light of the conceptual framework of servicescape, this study also attempted to isolate the controllable variables that can be utilized to increase the sports attendance. This study presents its significance not only in extending the application of servicescape concept to the sport industry, but also in providing suggestions for future empirical studies that would further identify these variables, gauge the relationship between those variables, and assess its impact on the sports attendance.
