As modern science and technology and warfare become to be advanced and precise, the weapon systems becomes more complex based on state-of-the-art technology. Therefore, firms in the defense industry continue to accelerate research and development for up-to-date weapon systems with high complexity which urge the firms to collaborate with the external organizations to obtain the knowledge required and eventually to reduce costs and risk. This study tries an empirical study about the effect of collaboration on the innovation performances from the network analysis perspective. By surveying collaboration relationships among 530 firms in the Korean defense industry, we analyzed the alliance network of the defense industry. Network centrality including degree, closeness, and betweenness centralities is investigated and then the relationship among the network centrality property, internal R&D capabilities and innovation is analysed. The results show that firms with high internal R&D capabilities place the firm at center of the network. On the other hand, except for the firms with highly connected centrality, no relationship was found between the internal R&D capabilities and its performance and in turn. these capabilities had both direct and indirect effects on innovation performances through mediated collaboration among firms. This study implied that Korean firms with a high internal R&D capabilities in the defense industry which utilize knowledge, information and resources within the network more frequently show more innovative performance. This result claims the policy makers to participate more firms in fostering open innovation for the defense industry.

This study analyzes whether cooperating with various types of partners contributes to a company's innovation performance as well as the moderating effect of absorptive capacity and appropriability that may affect learning in such relationship. The hypothesis is that cooperating with diverse partners will have a positive effect on the innovation performance since it acquires their knowledge and information. In addition, an analysis is conducted on the moderating effect of absorptive capacity and appropriability on the relationship between alliance portfolio consisting various partners and innovation since absorptive capacity that encourages learning is likely to positively moderate the relationship between partner diversity and innovation while appropriability, the capacity to protect the proprietary technology, is likely to undermine learning from partners. The result of the empirical analysis on Korea's key industries, machinery and automobile, using the 2010 Korea Innovation Survey(KIS) data on manufacturing shows that cooperating with various types of technology partners has a positive effect on innovation performance and moderating effect on appropriability.

In terms of the international air transport, the open skies policy implies freedom in the sky or opening the sky. In the normative respect, the open skies policy is a kind of open-door policy which gives various forms of traffic right to other countries, but on the other hand it is a policy of free competition in the international air transport. Since the Airline Deregulation Act of 1978, the United States has signed an open skies agreement with many countries, starting with the Netherlands, so that competitive large airlines can compete in the international air transport market where there exist a lot of business opportunities. South Korea now has an open skies agreement with more than 20 countries. The frequent flyer program (FFP) is part of a broad-based marketing alliance which has been used as an airfare strategy since the U.S. government's airline deregulation. The membership-based program is an incentive plan that provides mileage points to customers for using airline services and rewards customer loyalty in tangible forms based on their accumulated points. In its early stages, the frequent flyer program was focused on marketing efforts to attract customers, but now in the environment of intense competition among airlines, the program is used as an important strategic marketing tool for enhancing business performance. Therefore, airline companies agree that they need to identify customer needs in order to secure loyal customers more effectively. The outcomes from an airline's frequent flyer program can have a variety of effects on international competition. First, the airline can obtain a more dominant position in the air flight market by expanding its air route networks. Second, the availability of flight products for customers can be improved with an increase in flight frequency. Third, the airline can preferentially expand into new markets and thus gain advantages over its competitors. However, there are few empirical studies on the airline frequent flyer program. Accordingly, this study aims to explore the effects of the program on international competition, after reviewing the types of strategic alliance between airlines. Making strategic airline alliances is a worldwide trend resulting from the open skies policy. South Korea also needs to be making open skies agreements more realistic to promote the growth and competition of domestic airlines. The present study is about the performance of the airline frequent flyer program and international competition under the open skies policy. With a sample of five global alliance groups (Star, Oneworld, Wings, Qualiflyer and Skyteam), the study was attempted as an empirical study of the effects that the resource structures and levels of information technology held by airlines in each group have on the type of alliance, and one-way analysis of variance and regression analysis were used to test hypotheses. The findings of this study suggest that both large airline companies and small/medium-size airlines in an alliance group with global networks and organizations are able to achieve high performance and secure international competitiveness. Airline passengers earn mileage points by using non-flight services through an alliance network with hotels, car-rental services, duty-free shops, travel agents and more and show high interests in and preferences for related service benefits. Therefore, Korean airline companies should develop more aggressive marketing programs based on multilateral alliances with other services including hotels, as well as with other airlines.

Strategic alliance is increasingly becoming a popular strategy in the family restaurant industry. In general, strategic alliance can be defined as several brands collaborating in technology development, marketing, or production while keeping their independence as separate business entities. This study identified segments on the basis of sales promotion resulting from strategic alliances between family restaurants and card companies. This study further investigated how brand image, brand value, price fairness, customer loyalty and demographics are different among the segments. From the statistical analysis, three segments were found; 'short-period benefits oriented' segment, 'intangible and discount benefits oriented' segment and 'free benefits oriented' segment. Among the three segments, the 'free benefits oriented' and 'intangible and discount benefits oriented' segments had greater perceived brand image, brand value and customer loyalty than the 'short-period benefits oriented' segment.
