With the creation of a multi-platform media environment, contents production flows through convergence are being detected in the broadcasting contents sector, breaking the boundary between each other and breaking away from the rigid atmosphere of the past, when broadcasters were strictly divided or careful to comment on other programs. It is also quite encouraging that the method of collaboration has been done horizontally as a win-win strategy of co-existence and co-existence, not vertically based on one side's recognition or program popularity. Thus, this study noted the establishment of a world view to capture transmedia phenomena that transcend boundaries between each other to adapt and survive the rapidly reshaping media ecosystem at the base of this trend and to maintain the type of convergence and unrivaled value that emerges in various forms in the process. The research targets were selected for 'Usanseul' and 'Pengsoo', which are prominent in these movements and produce significant results at this point, and analyzed and compared to the results.

Large-scale online platforms such as MOOCs-Massive Open Online Courses, which provide a variety of educational contents, have provided a learning environment that allows students to freely access and learn anytime and anywhere. Currently, the proportion of online lectures and home-based learning is increasing, and portfolio or experience-based learning such as bootcamp, field activities, and team project-based group learning are also being actively carried out for educational outcomes. At present, interest in nano or microdegree focused on core technology in units of hours or credits is increasing significantly because such strategic intensive education enables effective learning in terms of continuity and efficiency of education. In an era of large changes in job market due to the reorganization of the industrial structure by new technologies, intensive education in specialized new technology fields such as smart mobility, big data, and artificial intelligence is much more conducive to finding a job. With this reason it is attracting attention as an alternative to lifelong learning are receiving In this paper we propose an educational platform that can efficiently and effectively support the purpose learning for the personalized microdegree education in the online learning era.

This study focused on developing strategies of cyber-compact city, combining compact city with information and communications technologies(ICTs), in order to enhance sustainable transportation. The cyber-compact city development is defined as a development that is able to reduce travel by ICTs and encourage people to use transit or non-motorized vehicles such as bicycles for ICT-induced travel (especially, discretionary travel) by compact and mixed land use. It can be achieved with combining cyber and compact strategies with respect to network, node, and area. For example, ICT network may use transit network facility, a transfer station may be a hub of ICTs, and transit influenced zone may work with ICT service area. We proposed three cohesive strategies for the cyber-compact city based on literature review and case studies on cyber and compact cities. The first strategy is a cohesion between public transportation and telecommunication network by centering on the two for national and urban spatial linkage structure. That is, cities or urban centers and its peripheral areas can be connected by rail network, and extra space of railway network can be used for constructing telecommunication network infrastructure. The second strategy is a cohesion between public transportation node and telecommunication node by building up regional and urban telecommunication centers near to or at main railway stations. For this strategy, telework centers and communication service centers should be established mainly at transfer stations. The third strategy is a cohesion between public transportation impact zone and telecommunication impact zone as transit oriented development.

SNS allowed users to serve not only as the content and message producer but as the consumer, with development into various types of SNS platforms. Instead of a traditional media structure of media-to-many and unspecified users, it also made it possible to achieve one-to-one or one-to-many interactions, regardless of time and space, through SNS platforms. Moreover, according to development of digital communication technology, IT, media contents and communication network have been mutually connected, though they were once separate. The changes in communication environments have caused rapid disorganization and reorganization in popular culture led by specific expert groups. Such trend has a greater influence on marketing strategies of enterprises. In other words, it will lead them to mostly introduce new information technologies, based on consumer market, and to strategically participate in SNS for promotion and marketing for their products and brands. Likewise, SNS has currently appeared as the main media affecting consumers' behaviors. In consideration of the importance of SNS features, which can stimulate responses of other users, analysis of main features affecting SNS user acceptance decision is required, as well as its utilization strategies. Accordingly, this study conducted division of SNS features into openness, quickness, interactiveness and economical efficiency to derive strategies for increasing the usage frequency of SNS and ultimately maximizing the expectation effect, in addition to an empirical analysis of effects of SNS features on usefulness, easiness and pleasure perceived in SNS, and SNS user intention.

This study aims to discover the implications through the analysis of the characteristics and design strategies of the regeneration of the post-industrial sites in the metropolitan the Beijing-Tianjin-Tangshan region. This study provides a basis for future research and theoretical strengths for post-industrial site regeneration practices. The results of the study are as follows. First, post-industrial site regeneration projects pursue diverse goals such as industrial heritage preservation, cultural creativity, and neighborhood revitalization in the Beijing-Tianjin-Tangshan region. Second, in the design process, the characteristics and spatial levels of the space are enhanced by utilizing the original industrial space, incorporating transitional space, and using industrial facilities of varying heights. Third, old and new landscape elements are harmoniously integrated through the rational use of industrial relics and the appropriate addition of new elements. Fourth, the design emphasizes ecological soil restoration and the use of native and adaptable plants that have the capacity to remediate polluted soil. Fifth, the design combines modern artistic elements, such as sculpture and graffiti art to enrich the site and promote the revival of the post-industrial site. Sixth, urban events and public activities are actively programmed to vitalize the regenerated site.

Korean card firms suffered harsh setbacks due to high credit defaults in 2002 and 2003, after issuing cards recklessly. Their key principle is changed to grow without damaging profitability and financial soundness. However, competition in the credit card market is heating up rapidly. Bank-affiliated card firms, having stronger sales networks and more capital than independent issuers, have increased their investments in card affiliates in a bid to develop new cash cows. Moreover, newly emerging independent card firms have waged fiercer campaigns to raise their credit card market share. In order to overcome these business conditions, S-card has settled on a strategy that focuses on stepping up marketing aimed at increasing charge card spending rather than credit card loans or cash lending services. Accordingly, S-card reformed the current business classification system of merchants, which was out-of-dated and originally built for the purpose of deciding merchant service fees only. They also drove customer segmentation planning to deliver the right customers to the right merchants. In this paper, we emphasize the problems of business classification systems of merchants with which most credit card firms have faced, and the need for reforming them not only to provide customer-tailored services but also to raise their business promotion excellence by reviewing S-card's process of customer segmentation.

The main aim of this paper is to explore the Korean development strategy in the context of trajectories of the economic development from 1961 to 2010. The fast and high growth in the period of 1961 and 2010 resulted from the 'export-oriented industrialization' through a combination of 'mass production-mass exports' and '(relatively) high productivity-low wages' up to the late 1980s, a mixture of 'mass production-mass exports' and '(relatively) high productivity-high wages' to the late 1990s, and a combination of the reformation of public and private sectors for overcoming the Korean financial crisis and the gradual improvement of the marketization and social safety net since 2000. With respect to this model of development, the global and national modes of regulation were established. Along with the formation of endogenous forces (as the national mode of regulation), that of exogenous forces (as the global mode of regulation) are the important rules of the game at the global level, which lead and stabilize the process of accumulation by the export-led industrialization in Korea. In this respect, the establishment of global modes of regulation is led by exogenous forces such as trade regulations, exchange rates, global-Korean industrial relations, and global regulations of loans to developing countries. On the other hand, the national modes of regulation are formed by endogenous forces such as the triangular relationship of the state, capital and labor.

This study examines the employment relations of TNC subsidiaries in Central and Eastern Europe(CEE). Specifically, this study analyzes the employment relations of Volkswagen subsidiaries, which has led the restructuring the CEE's automobile industry since the collapse of socialist regimes, and Hyundai subsidiaries, which has sought to cast employment relations through Greenfield Investment as a latecomer. After the collapse of socialism, with the massive inflow of foreign direct investment and the social legacy of weak labor unions, CEE has been included in the global production network as low-wage production base. Both VW and Hyundai have entered the CEE with their own characteristics and global strategies that have been developed in their home countries and have developed the local production. In the process, both have formed local employment relations, combining low-wage, unstable employment, and weak labor unions of CEE under their own strategy. In recent years, however, it has been doubtful of the sustainability of employment relations based on the advantages of low-wage production bases, as the pools of low-wage workforce decline and new union movements occur in CEE. These changes in CEE are an indication of the inherent contradiction of low-wage production base strategies.
