It is major strategy for SMEs to cooperate with other companies or Public Research Institutes(PRIs) as the essential technology is getting more complicated and technological life cycle is getting short. However, It is not easy to perform a proper cooperation with SMEs for PRIs, because they are accustomed to support SMEs in the short run. In addition, previous studies also have mainly focussed on finding determinants of performance as a consequence of temporary cooperation instead of long-term relationships among companies. Therefore this study analyzed which satisfaction is more effective to maintain the long-term cooperative relationship between PRIs and SMEs. As a result, it has found that when SMEs satisfy from quality of input like manpower supports R&D and context of the support program over the output like technological or economical performance, they intend to continue cooperation with PRIs. And this paper shows that the performance has mediated effect rather direct effect on long-term cooperation intention. In light of all the above, to cooperate with SMEs effectively, it will be suggested that PRIs enhance quality of support process and contents instead of quantity of support based on one-time cooperation.

The promotion of economic exchange and cooperation between North and South Korea is significant in two ways. First, the pursuit of economic interest can lead gradually to the unification of the national economies. Second, economic relations can serve as the first stride toward political reunification. There are, however, many difficulties in conceiving a strategy for economic cooperation between North and South Korea because of their differences in ideology and socio-economic system. Under these circumstances, a bid by either the North or the South to consider its specific ideology or socio-economic system absolute and to impose them on the other side would inevitably lead to confrontation and collision and deepen the division of the country. Therefore, steps to expand and develop economic and technological cooperation and comprehensive exchanges between the North and the South, with due regard to the development of bilateral relations, are in full accord with the interests of the both sides. It is clear that North Korea's changing attitude toward its environmental conditions is neither a policy of opening nor an ideological shift toward pragmatism, as has occurred in the Eastern European countries. Instead, it is a temporary tactic for breaking out of the economic stagnation caused by its rigid economic structure. In this light, we must.

This study analysed the institutional evolution of Korea's international cooperation of science and technology (S&T) from the viewpoint of the historical institutionalism. For this, it examined Korea's institutions for international S&T cooperation by dividing the whole period from the Korean war to the present into five sub-periods; period of technology aids, technology transfer, mutual cooperation, expanded cooperation, and highly sophisticated cooperation, respectively. It, then, reviewed the evolving process and characteristics of each period. In this study, the structure (environment), the actor (government), the institution of higher rank (science & technology policy) were considered as variables influencing upon the institutions of the international S&T cooperation. Upon this assumption, this study analysed how and through what evolutionary process the international S&T cooperation institutions have evolved so far. This study obtained the following conclusions; First, the study confirmed the existence of the "institutional layering" in the institutions of the international S&T cooperation in Korea. The momentums for the change of the institutions of the international S&T cooperation stem from international environment and domestic economic environment. They influence upon economic policy, industrial policy, and S&T policy, which, together with the actor (the government), again brings about the institutional evolution of the international S&T cooperation. Second, the institutional evolution of the international S&T cooperation is taking place gradually. As mentioned above, the momentums for the change of the institutions of the international S&T cooperation originate from international and domestic macro environment. These momentums do not directly influence upon the institutions of the international S&T cooperation, rather they give indirect influence, through other related institutions, upon the institutions of the international S&T cooperation and make its gradual change or evolution. This is because the institutions of the international S&T cooperation have the "institutional layering".

This study explores which organizational capital is important for the customer service center and how the organizational capital is linked to organization's performance through dynamic capability. In this study, total of 389 employees in customer service centers were surveyed for the analysis. The results indicate that relational capital and organizational culture were positively linked with collaborative behavior, capital share, and capital transformation. Also, structural capital was a significant factor in collaborative behavior. Organizational performance was positively affecting collaborative behavior and capital share. This study provides a practical guideline on how to manage organizational capital and supplement shortcomings for managers and counsellors at the customer service centers. Furthermore, the implications for the reinforcement and development of organizational capital were suggested in building a customer service center as a strategic and fundamental part of the company.

In a warehouse, because there exist frequent changes of stock status and the quality of some contents are influenced by the environment such as temperature, fast and accurate management of the warehouse's environment is very important for Warehouse Management Systems (WMS). However, due to the absence of a unified standard for the communication protocol between RFID nodes, the connection between RFID nodes can be broken in case of movement of a RFID reader to a region with a different protocol. Moreover, centralized MAC schemes for RFID communications in previous studies have severe problems. For an example, if a cluster header disappears from the cluster due to the cluster header's movement or bad channel conditions, the RFID member nodes of the cluster waste lots of time and energy to re-elect a new cluster header. Therefore, in this paper, we propose a WiMedia Distributed MAC (D-MAC) scheme for RFID communications and its cooperative relay transmission scheme for WMS applications Simulation results show performance improvement at the RFID node by using the proposed cooperative relay transmission scheme.

The technological innovation of IT manufacturing firms is the competitive tool for them to survive in the environment of an intensive competition. This technological innovation is critical in the survival of IT companies, but various factors should be considered to embody technological innovation effect. This paper aims to identify the determinant factors of the outcome which influence the technological innovation based on the IT companies, and set up a model for measuring technological innovation effect. A hypothesis was established for the impact relation between technological innovation effect, cooperative relation and government support level, which was verified through the structural equation model(SEM). As a result, the cooperation of IT companies and the governmental support affect the effectiveness of technological innovation. Eventually, government support for IT manufacturing firms derive business collaboration and continuous support is needed.

The World Wide Web (Web) is one of the most popular internet tool on now, In this reason most of common user, they understand the Web is internet and Web content is also important issues on this side. However, commonly Web content created by one of Web content creator and sometime they refer the another document and link. In these kinds of environments cause tile delivery of incorrect information or linking to another Web user. There are lots of way to protect the incorrect information deliveries to Web user and the most famous one is Computer Supported Cooperation Work (CSCW). This supports the multi-user environment on single system environment, but this needs more additional things in the current internet environment Current internet defined as distributed information network not tile traditional client-server environment. Specially, Intranet environments need to support the heterogeneous system environment like several Rinds of database, systems like PC, Mac and UNIX workstation, and etc. In this reason, we need collaboration and this would serve the common user interface to all of Web user. In these paper, we review the current concept of CSCW and grouoware that are major concept of collaboration and definition, classification and problem analysis of the collaboration. Finally, we suggest the construction method of collaboration environment for Web.

In conventional cooperative communication data rate is 1/2 than non cooperative protocols. In this paper, we propose a full data rate DF (Decode and Forward) cooperative transmission scheme. Proposed scheme is based on time division multiplexing (TDM) channel access. When DF protocol has full data rate, it can not obtain diversity gain under the pairwise error probability (PEP) view point. If it increases time slot to obtain diversity gain, then data rate is reduced. The proposed algorithm uses orthogonal frequency and constellation rotation to obtain both full data rate and diversity order 2. Moreover, performance is analyzed according to distance and optimized components that affect the system performance by using computer simulation. The simulation results revealed that the cooperation can save the network power up to 7dB over direct transmission and 5dB over multi-hop transmission at BER of $10^{-2}$. Besides, it can improve date rate of system compared with the conventional DF protocol.

The artificial intelligence (AI) of Non-Player Companions (NPC), especially opponents, is a key element to adjust the level of games in game design. Smart opponents can make games more challenging as well as allow players for diverse experiences, even in the same game environment. Since game users interact with more than one opponent in most of today's games, collaboration control of opponent characters becomes more important than ever before. In this paper, we introduce a cooperative strategy based on the A* algorithm for enemies' AI in the Pac-Man game. A survey from 17 human testers shows that the levels with our collaborative opponents are more difficult but interesting than those with either the original Pac-Man's personalities or the non-cooperative greedy opponents.
