Beginning from the premise that research competitiveness at the university level is the starting point for national competitiveness
as a whole, this paper analyzes the correlation between university research-related performance and the scholarly or academic
resources available through a country’s library system. An analysis of this correlation from two different angles — a macroscopic
approach considering universities in OECD nations and a microscopic approach focusing only upon universities in Korea — found
that there is indeed a significant correlation between university research performance and the scholarly information available
at libraries. A regression analysis of the two approaches also found that the more journal titles subscribed to by university
libraries and the higher their budget for materials, the greater the contribution university libraries make to university
research competitiveness in Korea as well as other OECD countries. In this light, in order for Korea to reach a level of research
competitiveness comparable to other OECD members, policies need to be created that will effectively increase the number of
journals subscribed to by university libraries.
The relative ans single comparator methods have been applied to determine 7 rare-earth elements and U, Th in Korean Monazites by 14.5 MeV neutron activation analysis. The (n, 2n) nuclear reactions are used for all elements except La, for which (n, p) reaction is used. Al is used as a flux monitor for the relative method and as a singlle comparator for the single comparator method. The analytical results obtained by the two methods agree well within 3% deviation except for Sm and Gd. These results are also compared with the result obtained by a single comparator method using reactor neutron.
This study performs a webometric analysis to explore the communication characteristics of scientific knowledge in a national
scholarly Web space comprising top ranking universities and government supported research institutions in South Korea. We
found significant differences in scholarly communication activity as well as linking behavior among different subspaces in
addition to institutional differences. We also found the usefulness of the ADM approach in analyzing the metric data containing
extreme outliers and discovered the directory model as the most appropriate. Page counts were found significantly correlated
with inlinks as well as with outlinks at the directory level in the whole scholarly Web space.
It is well known from previous research activities that R&D collaboration among economic actors for knowledge production is
very important. An accompanying analysis of the impact of R&D collaboration on innovative performance has to be conducted
for transferring knowledge to the globalized knowledge-based economy. When we first investigated previous research concerning
R&D collaboration, we found some limitations in the analysis methodology. In order to overcome these limitations in previous
research, we applied a Bayesian network for analyzing the impact of R&D collaboration in Korean firms on their innovative

Instrumental neutron activation analysis was used for the analysis of 25 trace elements in airborne particulate matter (PM) for air pollution monitoring. For the collection of air samples, the Gent stacked filter unit low volume sampler and two types of Nuclepore polycarbonate filters were employed. Samples were collected at selected sampling dates in suburban and industrial regions of Daejon city in the Republic of Korea. Mass concentrations and black carbon of PM were measured, and enrichment factors were calculated. The results were used to describe the emission sources and their correlation patterns.

Instrumental neutron activation analysis was used to measure the concentrations of about 27 elements associated with airborne PM 10 samples that were collected from a roadside sampling station at a moderately polluted urban area of Taejon city, Korea. The magnitude of their concentrations was clearly distinguished and spanned over four orders. If compared in terms of enrichment factors, it was found that certain elements (e.g., As, Br, Cl, Sb, Se, and Zn) are enriched in PM 10 samples of the study site. The factor analysis indicated three factors with statistical significance, which may exert dominant controls on regulating the metal concentration levels in the study area.

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.

Tritium and 14C concentration in hot spring water in Korea were determined. Tritium in the most hot spring samples could not detected and
concentration range was <0.5–1.31 TU. And 14C contents were ranged 1.7–78.6 pMC. From the 3H and 14C analysis, we found some hot springs are mixed with recent groundwater and hot spring water ages were estimated from 1,940
to 32,800 years. And also, 226Ra and 228Ra were determined simultaneously in hot spring water, and some other radionuclides were also analyzed. Content distribution
of 222Rn was 50–3,760 pCi/L, 226Ra was <0.003–0.15 Bq/L and 228Ra was below the detection limit.
The contents of H-3 and C-14 in groundwater and surface waters around low and medium-level atomic waste repository site in
Korea were determined. The concentrations of C-14 were in the range 0.186–0.287 Bq/L. The H-3 concentration of the groundwaters
and surface waters were <0.06–5.75 and 1.22–4.74 Bq/L. The average H-3 contents of west, north and south direction were 1.18 ± 0.12,
1.11 ± 0.78 and 2.85 ± 2.66. H-3 and C-14 concentrations in the south direction were relatively higher than west and north
direction samples. The surface waters sampled from catchment were four times higher than average H-3 concentration in precipitation.
The concentrations of H-3 and C-14 within 5 km area samples were much higher than other samples.
