As to 'E-Commerce Trade' or 'The Cross Border E-Commerce (CBEC)' which has shown rapid diffusion, Korean government is providing active support on the basis of idea that it has profound impact on increase of export. However, sporadic support propelled by various ministries and agencies are not effective and efficient at all on actual circumstances. Consequently, in order to promote consistency, effectiveness, and efficiency of supporting policy, it is desirable to clarify competent ministry and the duty of cooperation to the other ministries and agencies. For its own sake, it is necessary to amend each existing laws which scattered all over the business territory, or to legislate new enactments. Yet these methods are extremely tough to carry out, therefore, it seems that amending 'Electronic Trade Facilitation Act', which already exist and regulate 'paperless trade' would be a realistic alternative. For the diffusion of Korean CBEC especially export, in this study the author insists that amending this law to promote CBEC is the most reasonable way comparing to other ways with several reference materials.

In this paper, we propose a system of mimicking image classification for building database system. It better manages the format which recording the same advertisements multimedia in advertisements image. Recently, the work of converting database is made directly by the people. This work doses the media scanning, image editing and saving, and saving of advertising information (date, the media, the page and size, so far). Therefore, it is wasted a lot of time and manpower as inefficient business. To solve these problems, first of all we gain an image by digital camera, extract and classify candidate area of advertisements. Accordingly, our system saves database to comparison of the mimicking of all advertising and classify whether area of image is the new or existing advertising.

Innovative capacities and performance are essential for the growth of the IT industry and the development of the Korean economy. Global R&D centers are important sources of innovation in the IT industry. In order to identify the structure of the innovation environment of global R&D centers in IT industry, we conducted a field survey of 50 global R&D centers and 50 global R&D policy experts in IT industry. According to the empirical results obtained using the Linear Structure Model, it is suggested that, first, with regard to a short-term IT global policy, the direction of the Korean government's policy should act as a trigger to connect the research domain and the market domain; second, the government policy should act as a facilitator to connect the development domain and the research domain in the mid-term period; and, finally, the government's R&D policy should serve as a disseminator to connect technological capability and the market space domain in the long-term perspective. For an effective way of internationalizing innovation, IT policy planners should regard global IT R&D centers as the important components of national innovation system and encourage the effective involvements by them in the process of IT industrial innovation.

The friction and wear between machine components directly influence the energy loss and failure in various machines. Therefore, there is always a demand for finding methods to reduce friction and wear. Of the possible methods, lubrication is a widely used method for reducing friction and wear. In the case of lubrication, it is important to analyze the tribological behavior in the boundary lubrication because most of friction and wear occurs in the boundary lubrication regime. Cast iron has been regarded as a good material for industrial applications due to the excellent mechanical properties and high productivity. Especially, nodular cast iron is a material that shows better mechanical properties and wear-resistance compared with cast iron due to inclusion of spheroidal graphite. In this work, we investigated the tribological characteristics of nodular cast iron with respect to different counter parts in boundary lubrication regime. Sliding tests were conducted with SUJ2, ZrO₂, Si₃N₄ balls as counter parts using a pin-on-disk type tribotester. The results showed different friction and wear behaviors with different counter parts. The case of ZrO₂ showed the lowest wear rate in specimen and no significant ball wear. In case of SUJ2, it showed similar wear rate with ZrO₂ case in specimen and the highest friction coefficient. The case of Si₃N₄ showed the lowest friction coefficient, 33% lower than the case of SUJ2. It showed 16.9 times larger wear rate in specimen and 43% larger wear rate in ball compared to that of the SUJ2 case.

Rapid technological innovation led by digitization has significantly changed the business of digital content goods, and has led to the emergence of new forms of services, such as music streaming. However, whether the streaming service is a threat to the traditional downloading service is still under debate. In this study, we examine whether music downloading is a substitute for or a complement to music streaming by investigating the moderating effects of LTE technology penetration. Using a unique dataset on the online music market from a dominant music platform in Korea, we found that music downloading services are complementary to music streaming services, but this complementary relationship is significantly and positively moderated by the introduction of LTE technology.
