This study examines the technical level of North Korea's S&T and identifies areas for potential North-South cooperation. First, North Korean media is analyzed for situations and trends from 2010 to 2015. Despite some commendable achievements, North Korean S&T remains lacking in basic science and commercialization potential. Despite an awareness of the importance of international cooperation, North Korea is hampered by international sanctions and their own caution, consequently concentrating their efforts on China. Details of their cooperation reflect their interests and needs to a certain extent, although their collaborations were mainly in the form of meetings and conferences rather than active joint research. To assess the potential areas of cooperation with South Korea, this study also draws on interviews with NGOs and professionals working with North Korea. The country's present situation is analyzed and some practical examples of possible cooperation is suggested. North Korea has the potential to expand its cooperation not only with South Korea but with many other countries. North Korea also promisingly expresses interest in cooperation.

In an era of global competition, international cooperation in science and technology plays a key role in determining a nation's competitiveness. In fact, without international cooperation, it is almost impossible to keep in touch with the fast-changing technology. In regard to this, the Korean government put much efforts into building a strong base for global R&D networking. As a result, the environment for international cooperation has improved a lot. However, the outputs of international cooperation are still poor and fall short of expectations. With the importance of international cooperation in science and technology rising more and more, it is meaningful to examine the current situation of international cooperation in S&T and analyse the outputs of the cooperation activities to review our past and present international cooperation activities. Therefore, this paper focuses on analyzing the outputs of the MEST's international S&T cooperation programs in various ways and recommends ways to improve the outputs of the international cooperation in science and technology.

Inter-Korean Cooperation in Science and Technology will contribute to building the trust between S.K and N.K as a leading factor and cut down the cost of unification by diminishing the technology lag and the gap of economic level. This study has shown that we can increase the productivity of unified Korea Innovation system if we systematically analyse the present condition of the Inter-Korean Cooperation and promote Inter-Korean Cooperation. In this study, the author analyses the present condition of the Inter-Korean Cooperation with integrated framework of three aspects to clear up the policy of Inter-Korean Cooperation. First, in the national aspect, we make use of the notion of international cooperation and multilateral mechanism of an international organization. Thereafter, we make out the alternatives in the aspects of international relationship and legal and institutional view Second, in the unification aspect, we consider the Inter-Korean Cooperation by the notion of national innovation system. Thereafter, we make out the alternative in the aspect of a phase-dependent approach. Finally, in technology aspect, we consider the Inter-Korean Cooperation by the notion of technology gap, the framework of technology transfer, and technology dependency theory. As a conclusion, through this study, the author have tried to integrate the various theoretical backgrounds. As a result, the author could analyse the present condition of ter-Korean Cooperation in Science and Technology and team a good lesson from it; Therefore, we can use it as a means of evaluation on a cooperation program and prediction for the future status of cooperation.

The challenge of penetrating obstacles along with impact from weak multipath effects makes 60GHz signal very difficult to be transmitted in non-line of sight (NLOS) channel. So 60GHz system is vulnerable to obstructions and thus likely results in link interruption. While the application of cooperative technology to solve link blockage problemin 60GHz system should consider the characteristic of directional transmission for 60GHz signal. Therefore in this paper a system is proposed to solve the link blockage problem in 60GHz NLOS communication environment based on the concept of cooperation and also the beamforming technology, which is the basis of directional transmission for 60GHz communication system. The process of anti-blockage solution with cooperative communication is presented in detail, and the fast switching and recovery schemes are well designed. The theoretical values of symbol error rate (SER) using decode and forward (DF) cooperation and amplify and forward (AF) cooperation are presented respectively when the common channel interference exists. Simulation results demonstrate that the performance based on DF cooperation is better than the performance based on AF cooperation when directional transmission is used.

Recent advanced technologies enable multiple users to share the virtual environment and work together as they are collocated. Additional sensory information such as haptic could improve the cooperation. In this paper, we propose a server-client architecture with multi-rate haptic control to support a tangible cooperation. Using our approach, the system is able to maintain a consistent simulation state across multiple users as well as to provide a highfidelity stable haptic interaction. To verify our approach, we have developed an experimental application and tested the cooperation among multiple users. The results confirm that our system is able to provide coherency among clients as well as haptic transparency.

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".

The importance of international science and technology cooperation is growing more and more, but we do not know much about what criteria could be used to choose a science or a technology that needs international cooperation first and foremost among many kinds of competing sciences and technologies. Moreover, this selection process is affected by evaluators' or science/technology experts' perception, but we do not quite know what they actually see when they evaluate the needs of international cooperation. This study investigates the conditions that international science and technology cooperation is encouraged by scholars and researchers in various areas. Based on theoretical arguments of Transaction Cost Economics, Measurement View, and Knowledge-Based View, we drew hypotheses on when experts perceive greater needs of international cooperation. Using the classification categories of 10 major sciences and technologies, we collected data from 151 respondents from scientists in research institutions and colleges. As a result, we found that experts in science and technology areas perceive strong needs of international cooperation when the importance of focal science or technology is high and the relative national level of focal science or technology is low. Also, we found that the importance and relative level of focal science and technology have positive moderating effects each other. Lastly, we found that when experts evaluate their own major areas, the strength of positive relationship between the importance of science and technology and needs of international cooperation is diminished.

Since Deng Xiaoping's implementation of the "One China, Two Systems" policy, mainland China and the other Chinese regions of Hong Kong and Macau have cooperated in various ways to work towards successfully developing China's overall economy and industries. Particularly, cooperation between Guangdong Province and adjoining Hong Kong have been contributing to China's development, and this study explores their industry conditions including their current two governments policies designed to promote collaboration. The two partners were in a cooperative relationship even before the handover of Hong Kong, beginning with a "front shop, back factory" model built on their respective comparative advantages in labor-intensive industries in the 1980s. This cooperation effectively propelled the Pearl River Delta Region's industrialization process and enabled Hong Kong to transform from a manufacturing industry-based economy to a service industry-based economy. From the early 2000s, Guangdong and Hong Kong diversified their collaboration project from culture to high-tech. Also, both authorities produced several types of policies not only to promote both industries but also to harmonize their two different economic levels and models. As a result, the Guangdong and Hong Kong economies have developed remarkably well during the past two decades and continue to form future plans that carry plenty of optimism. Nonetheless, this study showed discrepancies between engineers and scientists from the two areas in their perception of their technology and science cooperation. Hong Kong experts were more negative in their responses but noted some successes of the collaboration, while Guangdong's group showed overall positive responses. This difference results from an unbalanced role in cooperation. Hong Kong's side responds to cooperation plans and takes on leading roles with more frequency than Guangdong's side in actual cooperation project processes.

Korea has good mutual relations with Russia and China in many fields, not just in science and technology, but also in trade. That is, it stands on a point of time in which an epoch-making turning point for mutual interests could be realized depending on how to join Russia's high technology with Korea's industrial technology with capital, or how to connect Korean -Chinese mutual concern and each other's advanced technology. The purpose of this study is to present scientific and technical information management policy for efficient su n.0, pport for technical cooperation with Russia and China. Bearing this purpose in mind, the concept of technical cooperation along with scientific and technical information management policy was closely examined. The correlation between the progress of technology and the type of scientific and technical information was examined, while the flow of scientific and technical information accompanying technical cooperation was studied. The methodology adopted for this study includes document research, empirical analysis and fact-finding survey. For document research, the writer analyzed the contents of scientific and technical information managing operations and the types of information to be utilized in the course of technical cooperation by examining domestic and foreign documents on international technical cooperation. For empirical analysis, the contents of actual results of scientific and technical information managing operations for technical cooperation with Russia and China were put in order and analyzed, while contents of survey conducted by organizations related to these countries for technical cooperation were synthesized and examined for fact -finding survey.

Coded cooperation is a promising user cooperation scheme. In this paper, we first propose a novel network-coding-based coded cooperation scheme. When a user decodes its partner's information correctly in the first frame, it transmits the combination of the partner's parity bits and its own parity bits through network coding in the second frame. This is distinct from the classical scheme, where the user only transmits the partner's parity bits during cooperation. We analyze the outage probability of the proposed scheme, and show that it achieves a full diversity order. Numerical evaluations reveal that the proposed scheme outperforms the classical scheme when the inter-user channel is poor, yet is worse when the inter-user channel is strong. Also, the results show that the proposed scheme always outperforms that of no cooperation in various channel conditions while the performance of classical scheme is worse than that of no cooperation with the poor inter-user channels. This means that the performance of the proposed scheme is more stable than the classical scheme and the proposed scheme is more tolerant to the poor inter-user channels. To combine the advantages of the proposed scheme and the classical scheme under different inter-user channel conditions, we propose an adaptive solution. This adaptive scheme enhances the system performance considerably in all channel conditions in spite of the inter-user channel quality, at the expense of only one acknowledgement or non-acknowledgement bit.
