This study sought to look at why Facebook and Twitter, which have dominated the social media market, are moving away from other services. To this end, we sought to identify the causes of churn in terms of firm-level strategic direction and resource allocation, which have not been actively presented to the studies. For this purpose, this study divides the social media firm's strategies into horizontal expansion strategy and vertical integration strategy based on the existing reports and researches, and how each of the representative firms' strategies affects users' switching behavior. As a result, there was a significant difference in the strategic direction of the social media firm, when a horizontal expansion strategy is taken, user's switching intention is higher than when a vertical integration strategy is taken. In addition, the switching intention according to the level of dependence showed that the lower the dependence on social media, the higher the intention to switch to other media. The findings are expected to provide highly realistic and concrete strategic alternatives for a variety of economic actors, such as individuals and companies who want to do business using social media.

This paper proposes the rotor position and rotor speed estimation for an interior permanent magnet synchronous machines (IPMSM) using Unscented Kalman Filter (UKF) in alpha-beta coordinate system. Conventional algorithms using UKF are based on the simple observer model of IPMSM in d-q coordinate system. Rotor acceleration is neglected within the sampling step. An expansion of the observer model in an alpha-beta coordinate system with the consideration of the rotor speed variation provides the improved rotor position and speed estimation. The results show good stability concerning the expansion of observer model for the IPMSM.

The cross-border trade(CBT) market has grown significantly due to the global spread of the Internet and mobile. China has become a very important market because of its share of 78% in 2016 in the export of korea's CBT.

This study investigates empirically the export competitiveness of Korea and Japan in America by calculating 4 indexes such as market share index(MSI), export similarity index(ESI), market comparative adventage index(MCAI) and market share expansion ratio(MSER)-export similarity deepening ratio(ESDR). The empirical finding of this analysis shows that Korea is competitive in the labor-intensive products and Japan in the technology-intensive products. This result also meets the general understandings that Japan is superior to Korea in the export competitiveness such as value added of goods, etc. Therefore, in order to strengthen the export competitiveness of Korea in the US market, it's desirable for our firms and government to improve the quality of product ranges by developing technologies focused on the higher value-added products.

To objectives of this study are to investigate which antecedent variables have significant effects on consumer perceived satisfaction or loyalty and to examine whether these factors have differences between Korean and Chinese customer. To test the hypotheses, such antecedent variables as the product quality, service quality, store reputation, store image. All variables are significant factors in both Korean and Chinese customer. Under the current increasingly rapid competitive market, product/service quality, store reputation/image can provide customer satisfaction and loyalty, can generate continual customer expansion of current customer through the reuse intention and can contribute to the expansion of new customers.

Emerging digital economy, e-business, especially business to business(B2B) electronic commerce is understood one most single critical competitive weapon for organizations' global competitiveness. According to government white paper, Korea's electronic commerce records expansion stage in its volume and variety. Although Korea has remarkable EC records, still some differences are existed compare to the developed countries. IT in the developed countries, played an engine for the economic restructuring as well as for the economic growth. But in Korea, it's not fully utilized by the reasons of economic and noneconomic bottlenecks. Under the digital economic surroundings, EC or e-Business, is a business system to achieve the economic efficiency in the levels of an organization as well as a nation. So, we have to find the ways to utilize our EC infrastructure to contribute for the nation's global competitiveness. To find the way, this study recommends two types of policies, pull and push, beyond the OECD's suggestion, to government in order to expansion of EC, especially B2B EC.

The Oriental thought does not stay in self, society, or state, but goes further to expand its bounds as "Chunha(the World, 天下)", which is not just the spacious expansion but the moral expansion. It provides a clue to overcome the limitations of the Western international political thought resulting in nationalistic tendencies. Such a cosmopolitcan orientation in the East can be found in the concepts of "Wangdo(Just Way, 王道)", "Yinjung(Benevolent politics, 仁政)", which make Hua(harmony, 和) its essential characteristics. If the East Asian community is formed, it should be based on universal principles that all East Asian citizens can sympathize with from below, not in a one-sided and coercive way. In this regard, the formation of "Sahaeyilga(四海一家, We are the world)", the "Chunha天下" based on the philosophy of the peace seeking 'similarity' in 'difference', can provide philosophical clues to resolve the conflicts and contradictions of the current isolationalist and confrontational international situation.
