  • GPS location information storage included in the HD black box is using a unique manner for each manufacturer does not have a specific standard. In this paper, in order to overcome the limitations of the storage space and thereby the image quality according to store GPS position information deteriorate to solve the problems that cause, we propose the location information concealment method included in the HDTV video content using a essential hidden region. HDTV video content is a Border Extender of 8 lines in the frame to the bottom of the compression will be required. This was inserted into the image of a gray scale used in block form in order to space the current position information is concealed to prevent image degradation. The proposed method was confirmed using real HD black box, there are more difficult to interpret the format of the ASCII code re-edit the location information when the compression effect disappears with the existing security zones added. Therefore, the proposed method is suitable for location-based services, such as Facebook or Youtube videos.

  • Since the 1960s, Korean welfare regime has been characterized by developmental welfare regime, of which invisible welfare programs like relation-based welfare are one of core elements. Developmental welfare regime of Korea has been dismantled after 1990s by the internal and external pressures. Focusing on the declines of relation-based welfare, this study examines the dismantle of developmental welfare regime of Korea. Since the late-1990s, the roles of inter-family income transfer and public income transfer are significant changed in terms of each share of total household income and each contribution of poverty alleviation. In other words, the role of public welfare has been growing while that of relation-based welfare has been decreased in the last twenty years. For the sake of a successful welfare regime transition in Korea, redistributional function of public welfare is quite important, but the development of reciprocal social economy and open community are also needed. Because, at this time and in this place, traditional welfare state building strategy is not proper in many aspects. However, it is impossible to achieve the development of reciprocal open community by restoration of relation-based welfare which has been already declined. This study regards enlargement of social economy or third sector as a development of reciprocal open community, and insists that cooperatives are especially worthy of notice.
