This study identifies possible determinants that may have influences on the switching behavior from the current payment system of credit or check cards to the easy payment service based on push-pulling-mooring model. And this research empirically tests how those determinants affect switching intention to the easy payment service. The moderating effect of policy expectation is also taken into account. The findings show switching intention to the easy payment service is influenced by the followings: dissatisfaction with the current payment system as a pushing factor, perceived easy of use and trust in easy payment service as pulling factors, and affective/cognitive inertia and unfavorable subjective norm as mooring factors. The results also show that moderating effect of policy expectation exists in the relationship between perceived ubiquitousness and switching intention.

Due to a growing demand for the second-hand product, especially for the expensive one, the warranty and maintenance policies for such products have been studied to improve the product reliability of late. In this paper we study a periodic maintenance model for the second-hand product which is purchased by the customer at the age of $x$. When purchased, the dealer provides a warranty of a fixed length during which the product is maintained periodically to reduce the failure rate of the product and thus, to improve the reliability after each maintenance is served. If a failure occurs between two successive maintenances, only minimal repair is conducted. As for the warranty policy, we adopt free non-renewing repair action on each failure, in addition to the periodic maintenance service during the warranty period. Thus, under the given warranty policy, all the maintenance and repair costs incurred during the warranty period are charged to the dealer. For the proposed periodic maintenance scheme, we formulate a cost model to evaluate the expected total cost charged to the dealer during the warranty period and derive an optimal upgrade level of the failure rate at each maintenance to minimize the expected total warranty cost from the perspective of the dealer. We also present numerical results for an optimal upgrade level based on the proposed methods.

Media-related regulations can be classified into two categories; regulations of individual media contents and regulations regarding the entry to and withdrawal from a certain field. In this dissertation, ownership regulations are regarded as legal and political measures so as to prevent the monopoly and oligopoly of public opinion, and to secure its diversity. Every country has its own regulation model according to its particular media environment. Korea too is obliged to actively respond to its environmental changes, at the same time vitalizing the media industry and protecting consumers' rights and interests. Strong political intentions to protect the public interest is necessary when it comes to media regulation policies, especially in the circumstances that public interest is an industrial priority. As the convergence of broadcasting and telecommunications is leading to a major shift in the media industry, the regulation of cross-media ownership is an issue involving potential conflicts among media-owners, non-governmental organizations and the authorities concerned, depending on their various viewpoints regarding the media industry. In this paper, an attempt was made to search necessity of redefining 'public interest', which is the logic behind the restriction of cross-media ownership, and to reconceptualize issues on the centralization and diversity of media. First, an examination of the actual conditions of newspaper companies was carried out in order to reinvestigate domestic cross-media ownership issues, which is represented by the cross-ownership issue of newspapers and broadcasting stations. Next, the dilemma of policies stimulated by the fusion of media was discussed based on cross-media ownership restrictions, and the need for efficient conflict control was suggested. Finally, proposals on the independency and public confidence of media-related policy-making authorities, the rationalization of regulation models, an itemized discussion on cross-media ownership regulation issues, the elaboration of measures for a balanced development among media were made. It could be found that a number of foreign countries were still facing challenges to prevent monopoly and oligopoly of the public opinion and the industry. A solution to settle disagreements about the dilemma of the media industry, including the cross-media ownership regulation issues, must be arranged on the grounds of 'mutual respect of public interest and industrial interest', In Korea, an ease on the ownership regulations adapting to the change in the media industry may be considered, however the softening of the cross-media ownership regulations must be approached with the utmost care. Paradoxically Relieving cross-media ownership regulations may be considered the foundation of a richer field of journalism, where there is no need for concern over the monopoly and oligopoly of public opinion.

In this study, in order to analyze the general awareness of the nuclear power according to the controversy of thyroid cancer around nuclear plant, we investigated risks, preference and economics regarding type of power, and awareness of pre-post nucl ear power targeting the Busan Metropolitan residents. As a result, there has been a change in people's awareness of nuclear power as a result of the controversy thyroid cancer around nuclear plant. Especially, there was the greatest increase in the risk factors compared to before the event(p<0.05). Negative awareness of nuclear risk was shown to be expressed differently accor ding to the difference between groups. It is thought that this is due to the different prior experience of each individuals or obtained information through the interaction with others rather than on scientific and objective grounds. In order to establish a nuclear power policy considering the level of the people in the future, it seems that the efforts to understand the attitudes and opinions of people about nuclear power and above all, a scientific trust in nuclear power should be guaranteed.
