Through the research, we found that the organizational systems of social enterprises in Europe have both properties of limited companies and stock companies in traditional organizational structures such as cooperatives, mutual companies and associations. However, social enterprises pursue interests of entire community, allowing the interested parties to join them in comparison with cooperatives. And for finance, most of the countries mainly use public fund such as national grants, but they are using more sales revenue. However, in our country the organizational systems of social enterprises have been introduced as the government and academic circles discussed expansion of social employment within a short period. So Korean enterprises tend to depend on national support rather than profitable activities for finance. Therefore, we need to develop a Korean convention or social agreement for the organizational systems of social enterprises. Furthermore, it is important for social enterprises to secure safe finance through development of social services and social cultures such as donation.

Recently, the amount of money that foreigners buy from online shopping sites in Korea has been increasing, especially by Chinese consumers. In this study, we researched the effects of Chinese consumers' reviews, inquiries, and bargains on loyalty, and how these effects differ by gender so that Korean online sellers can take advantage of these opportunities. In order to verify the research model, a survey was conducted on Chinese consumers with online purchasing experience and 231 valid samples were collected and analyzed. As results, reviews, inquiries, and bargaining had the positive impacts on the loyalty of Chinese consumers. The impact of reviews on loyalty was higher in women, and the impact of inquiries and bargains on loyalty was higher in men. This study can help Korean online sellers effectively respond to Chinese consumers' reviews, inquiries, and bargains needs. This study, also, can help they understand and deal with the difference between the effect on reviews to women and the effect of inquiries and bargaining to men.

As the process of economic globalization deepens market uncertainty and severe competition, modern companies are tend to rely on non-market, socio-economic mechanisms such as trust, collaboration, and interdependence, They are being more influenced by cultural economic mechanisms like networks, embeddedness, and placeness rather than explicit cost-reductions. This paper analyzes the characteristics of industrial clusters, the formation of social capital, and the process of institutionalization by comparing two distinctive types of clusters, say Teheran and East-Gate Valleys in Seoul, Korea. The one is mainly consisted of IT industries with increasing vertical integration supported by venture capitals and favorable business infrastructures. The other cluster has long been a traditional CBD frame of Seoul and has transformed to the most dynamic and productive area, characterized by one-stop 'R&D-production-distribution-consumption-after sales services'. The study of the developmental trajectory and key characteristics for these kinds of clusters can give us insight for the cluster theory. This paper firstly reviews the similarities and differences between the social capital in general and that of industrial clusters. It then profiles the growth of the two clusters over the past decade, and compares the current spatial and business structure of the two clusters, focusing on transactions costs, the creation and flow of information, and the local institutions. The paper concludes with some comments about the prospects and perils of the two types industrial clusters of Seoul.

In today and near future, most of the commercially manufactured IT products will be evolved into software convergence product. Recently, the embedded software products is called as 'Software Convergence Products.' This phenomenon does not simply show the trendy fashion, but has the seriously implication that the functionalities of IT product is accomplished and evolved via software technology, not via mechanical nor electrical means. It will become true that the quality of the convergence product is dominantly governed by the software it uses. Meanwhile, we are facing with the threatening fact that software defects in the mass products will requires tremendous amounts of cost proportional to the quantity of the product. We can remind ourselves of the disasters that have been already happened, such as Automotive recalls, Smart-phone recalls, and others. In software engineering, there have been large amount of work done in software quality improvement for the past couple of decades. Software process improvement, and testings are the representative ones. But we are facing with limitations of those traditional approaches in current convergence industry; exponentially increasing software sizes and rapid changes in software technology. In this paper, we analyze the characteristics of the software convergence industry, the limitations of the traditional Software quality improvement approaches. We suggest a new approaches in software quality improvement in different angles of thought and philosophy.

Consumers have been increasing their interests in firms' ethicality as well as in the features of the firms' products when they decide to purchase a certain product. Recently, fair trade is considered to be a type of ethical marketing in the business-to-consumer market. In this regard, the effects of fair trade-based marketing on firm performance have become the center of academic and managerial concerns. Despite this importance, few studies have investigated whether fair-trade is a source of competitive advantage or just a cost of doing business. The present research attempts to provide evidence of how fair trade-based marketing influences competitive advantage. Two experimental studies were conducted to explore consumers' purchase intention, which can be a proxy of competitive advantage, in a foreign product-consumption context. Drawing on the stakeholder theory, the first study was performed to examine the effects of fair trade marketing on consumers' purchase intention through a within-subjects design. In addition, building on the signal theory, the second study was executed to test the effects of a fair trade mark on consumers' purchase intention. The findings of the current research reveal that consumers prefer fair trade-based products to others and that when it comes to fair trade-certified products, consumers are more likely to purchase products with that certification than otherwise, even when those products are sold at higher costs than rival products. Interestingly, the results of this research present that there is a significant difference of consumers' purchase intention of a fair trade-based product between two different marketers. This implies that fair trade-based products should be differentially distributed and targeted at a certain type of consumers.
