In recent years, the topic of knowledge production has been widely investigated in the advanced countries. However, the process
by which knowledge is produced in the developing countries has not been fully explored or characterized. In Korea, the science
and engineering fields strongly reflect systems of knowledge production in the universities and demonstrate the dynamics of
systems of innovation for knowledge production. Through using a case study including data for knowledge production, in the
field of information and telecommunication, the following general trends were observed. Firstly, there has been a trend towards
increasing the capabilities for knowledge production, via domestic and foreign collaboration. Secondly, there has been an
increasing trend towards the diversification of knowledge sources such as university-industry, and university-public research
institutes. Finally, the establishment of a nation's knowledge base is influenced by governmental research and development
The notion of knowledge-based economy premises that technological knowledge be created, accumulated and disseminated through
the interactive learning among principal actors in the national system. This paper analyzes, from a dynamic perspective, the
structure of inter-industrial technological knowledge. Both human-driven disembodied channel and capital-driven embodied channel
are investigated based on network analysis. The set of empirical data covers the Korean manufacturing sector during the 1980s.
Overall, density of network tends to be increasing over time, implying that knowledge network becomes expanded and intensified.
A number of distinctive features are identified between knowledge types and industrial categories. The findings in turn render
important policy implications that should be addressed when developing technology policy. Clearly, the policy framework needs
to be industry-specific and country-specific in accordance with the development stage and industrial structure of reference
This study examines network topologies of interdisciplinary research relationships in science and technology (S&T) and investigates
the relational linkages between the interdisciplinary relations and the quality of research performance. A network analysis
was performed to evaluate the General Research Grant (GRG) program, an interdisciplinary research funding program of the Korea
Science and Engineering Foundation (KOSEF); the dataset covered the 2002–2004 period. The analytical results reveal the hidden
network structure of interdisciplinary research relationships and demonstrate that the quality of research performance might
be enhanced not only by interdependent pressures placed on various research fields but also by accumulated research capabilities
that are relatively difficult to access and reproduce by other research fields.

Instrumental neutron activation analysis was used to assess the concentration of the inorganic trace elements in Korean women’s
blood serums. It was found that a high concentration of Na and Cl incurs an analytical interference, but the 12 elements such
as Br, Ca, Cl, Co, Cr, Cs, Fe, K, Na, Rb, Se and Zn could be determined under the condition of an interference minimization.
Serum samples collected from 63 women were analyzed and the concentration level and range of the elements were evaluated.
NIST SRMs were analyzed simultaneously for quality control. The average values of the Na and Cl determined in the serum samples
were 3,365 and 3,533 mg/l, Ca was 96.4 mg/l and K was 191 mg/l. Besides, Br, Se and Zn have a concentration level of 6.46,
0.13 and 0.98 mg/l, respectively. It was found that there is no significant difference between the present values and the

Depth distribution of239,240Pu and137Cs in the soils of South Korea have been studied. The average accumulated depositions were estimated roughly to be 54.8±32.1 Bq·m–2 for239,240Pu, 1.6±1.0 Bq· ·m–2 for238Pu and 1982.8±929.1 Bq·m–2 for137Cs. The activity ratios of239,240Pu/137Cs in soils were found to be in the narrow range of 0.0153 to 0.0364 with a mean value of 0.0230±0.006. The concentrations of239,240Pu and137Cs in soils decrease exponentially with increasing the soil depth. A significant correlation was found between the concentration of239,240Pu and that of137Cs. The activity ratios of239,240Pu/137Cs tend to increase slightly with increasing soil depth.
This article reports findings from a study of the relationship between citation measures (impact factor and its quartile)
among international composition of editorial board and foreign authorship in 17 Korean SCI journals for the three 5-year periods,
1995, 2000, and 2005. With few exceptions, the relationship between international editorial board composition and foreign
authorship and citation measures was non-existent, at p > 0.05. However, the international members on editorial boards and foreign authorship of papers in Korean journals have increased
greatly over the three 5-year periods, and there has been to a certain degree growth in the visibility and performance of
Korean SCI journals in terms of impact factors, but not their quartiles.
The concentrations of3H,137Cs and239,240Pu were determined in surface seawaters collected at 21 sampling stations around Korea from October of 1994 to May of 1995. The results were consistent with the past data observed in the North Pacific. The concentrations of3H and137Cs did not show much difference no matter where the samples were taken. Due to the limited distribution of sampling points, no systematic change in3H and137Cs levels with latitude was observed. On the other hand,239,240Pu concentration in the East Sea (Japan Sea) was somewhat higher than that in the South and the Yellow Seas, although the data on239,240Pu concentration were not enough to explain the reason. The activity ratios of239,240Pu/137Cs in surface seawater ranged from 0.13% to 0.44% with a mean of 0.25±0.08%. The activity ratios were lower than those of the global fall-out level, 1.1%. This result presumably arose from the different behavior of the two radionuclides in seawater.

Summary This paper elaborates on the Triple Helix model for measuring the emergence of a knowledge base of socio-economic systems. The ‘knowledge infrastructure’ is measured using multiple indicators: webometric, scientometric, and technometric. The paper employs this triangulation strategy to examine the current state of the innovation systems of South Korea and the Netherlands. These indicators are thereafter used for the evaluation of the systemness in configurations of university-industry-government relations. South Korea is becoming somewhat stronger than the Netherlands in terms of scientific and technological outputs and in terms of the knowledge-based dynamics; South Korea’s portfolio is more traditional than that of the Netherlands. For example, research and patenting in the biomedical sector is underdeveloped. In terms of the Internet-economy, the Netherlands seem oriented towards global trends more than South Korea; this may be due to the high component of services in the Dutch economy.

For air pollution monitoring, about 1300 airborne particulate matter samples were collected by using a low volume air sampler
and a polycarbonate filter at two sampling sites in an urban region, Daejeon, the middle of Korea from 2003 to 2006. Mass
concentrations of the black carbon were measured using a smoke stain reflectometer. The concentrations of 24 elements in the
collected samples were analyzed by using instrumental neutron activation analysis, and its temporal trends and enrichment
factors were investigated under different environmental conditions. Analytical control was carried out by using certified
This paper suggests an
international benchmarking method of disembodied knowledge flow structure.
Using patent citation as a proxy measure of disembodied knowledge flow,
national knowledge network is developed. Structural equivalence measure is
applied to comparing the knowledge network of Korea and Taiwan with that of
USA. Static and dynamic comparison make it possible to benchmark disembodied
knowledge flow structure efficiently and identify convergent and divergent industries between
developing countries and USA. It is also a meso-study that could be conducive
to building a comprehensive analytical framework of national innovation system.
