We establish an algorithm that explains the evolutionary patterns of artifacts and construct a mobile phone phylomemetic tree using a very simple statistical method with the principles of biological evolution. Based on the results, we find that the change of an artifact and society's relationship to that artifact follow a certain pattern. First, the evolution of an artifact's characteristics takes a direction that differs depending upon the characteristics involved. In addition, the outcome of this evolution is connected to the general human perception of consumers. Second, each of an artifact's characteristics evolves sequentially rather than simultaneously. Furthermore, characteristics of one artifact that are held in common with those of other artifacts, such as a digital camera and PDA, have an effect on the speed of that artifact's evolution. Finally, producers that launch many evolved artifacts end up in a leading position in the marketplace. © 2013 PICMET. Source

The data transmission of sensor nodes which detect events might be affected by their neighbor nodes located in their communication range. Thus, we analyze the energy consumption of sensor networks as a function of the number of cluster heads considering the above two options, multihop-based communication and the case where a neighbor node is in the transmission range for communicating data. This helps us to elect the number of energy-efficient cluster heads in a more practical manner. Also, we determine the effect of electing the number of cluster heads by restricting the local cluster size. © 2013 Choon-Sung Nam et al. Source

The prevention or elimination of causes of death in early life has resulted in a population consisting of an increasing proportion of elderly people. With this increasing proportion of elderly people, we will encounter many problems like a degenerative disease, the depletion of welfare money like public medical insurance and the lowering growth rate of nation, and so on. In this research, at first every possible expected issue related to aging population was drawn through literature review and expert interview. Then products and service need to tackle aging population issues was drawn. The last step is to draw key technologies to realize these products and services. Among such technologies, we studied which technology belongs to the HCI technology, and carried out survey of the impact of each technology economically or socially. Based on these results, we presented a R&D strategy of the Korean government for the HCI technology development in response to the future aging society. © Springer-Verlag Berlin Heidelberg 2013.

'Basic research' is based on epistemological and intentional criteria. In terms of science policy, however, these criteria imply contradictory views on investment in 'basic research'. The former espouses the linear model of innovation and encourages policy-makers concerned with economic problems to expand investment on basic research. However, the latter can collide with the policy norm of policy-makers and discourage investment in 'basic research' in an institutional setting where the nation-state prevails over scientists, as in South Korea. Emphasizing policy ideas and policy learning, this paper empirically shows that changes in investment priority and the emergence of new concepts about 'basic research' are co-products of a policy paradigm of the linear model and a policy norm of industrial competitiveness in Korea. Specifically, emphasis was placed on the balance between pure and oriented basic research, but moved on to 'oriented basic research', 'basic engineering', and to 'basic research' coupled with 'woncheon-technology'. © The Author 2014.
