The National Innovation System (NIS) and the automobile industry in South Korea
Since Freeman (1988) suggested the concept of National Innovation System (NIS), NIS has provided a foundation for understanding the organizational interactions that engendered innovations in industry. The definition of NIS varies with the context in which innovation activities are performed and evaluated. The multiple definitions of NIS can be classified by their scopes (Chung 2002). In a broad sense, NIS encompasses all the interrelated institutional actors that create, diffuse, and exploit innovations. On the contrary, according to the narrow definition, NIS is a complex of innovation actors that are only directly associated with the generation, diffusion, and appropriation of technological innovation. Research and Development (R&D) departments, universities, and public research institutes can be taken as examples. In this report, primarily the narrow definition of NIS will be adopted, and the role of NIS in the South Korean automotive industry will be accordingly discussed. --
How to Compare the Scientific Contributions between Research Groups
We present a method to analyse the scientific contributions between research
groups. Given multiple research groups, we construct their journal/proceeding
graphs and then compute the similarity/gap between them using network analysis.
This analysis can be used for measuring similarity/gap of the topics/qualities
between research groups' scientific contributions. We demonstrate the
practicality of our method by comparing the scientific contributions by Korean
researchers with those by the global researchers for information security in
2006 - 2008. The empirical analysis shows that the current security research in
South Korea has been isolated from the global research trend
Hybrid Spam Filtering for Mobile Communication
Spam messages are an increasing threat to mobile communication. Several
mitigation techniques have been proposed, including white and black listing,
challenge-response and content-based filtering. However, none are perfect and
it makes sense to use a combination rather than just one. We propose an
anti-spam framework based on the hybrid of content-based filtering and
challenge-response. There is the trade-offs between accuracy of anti-spam
classifiers and the communication overhead. Experimental results show how,
depending on the proportion of spam messages, different filtering %%@
parameters should be set.Comment: 6 pages, 5 figures, 1 tabl
