In this study we performed risk evaluation based on parameters using the SINMAP, GIS-based extended program in order to predict ground disaster that is frequent recently. As for the risk evaluation, in order to understand the effects of parameters, we defined that the ranges of internal friction angles and T/R values as important variables had three and four patterns, respectively. The results of the interpretation were compared with those of the existing landslide in order to identify landslide flow and to evaluate the applicability of the parameters. The analysis of the geomorphologic saturated zone showed that the boundary saturated zone and the saturated zone were almost consistent with the site of avalanche of earth and rocks and the area of underground water convergence was correlated to the area where collapse started, indicating that the geomorphologic saturated zone may serve as an index for estimating possibility of landslide when used with slope distribution, colluvial soil, and structures inducing landslide in combination. When the lower limit of the internal friction angle increased more, the upper threshold decreased by 50 to 70% and the influence on the stability index was higher, but the influence was declined within the range of lower wetness index. The analysis of changes based on wetness index range showed that all the groups have similar SI distribution, except for the one in which mean altitude values are applied, indicating that the results are susceptible more by the internal friction angle than by the wetness index.

Patent information, which is generated under a specific, objective rule for a prolonged period of time, has the properties of technology, right, and management. Because of these characteristics of patents, patent analysis is used to identify R&D capacities and performances, and management strategies of a given nation or enterprise. In this paper, we analyze LTE essential patents which are key IPRs for implementing standardized LTE technology and major weapons in a global patent war. Total of 2,307 LTE essential patents, published and registered applications from European Telecommunications Standards Institute(ETSI)'s online IPR database as of January 2011, are analyzed in quantitative methods. The analysis results present status and statistics of LTE essential patents by major countries, applicant companies and technical fields. And a comparative study is done using 4 patent indices limited to the LTE essential patents issued in the United States. It is expected that results herein are useful for not only figuring out the technological competitiveness of countries and companies in LTE market, but also suggesting a guide to strategic IPR management for related industries.

Today, many learned societies are very interested in publishing international journal, especially for titles from non-English speaking countries. In Korea, there is not many studies on publishing international journals except for some cases trying to internationalize domestic journals. This study analyzed international factors of domestic 143 titles offering DOI by KoreaScience. The analysis showed that many of these journals have low impact factors and editorial board without a lot of foreign scholars. Some titles don't have online submission platform or English websites. It is recommended that domestic journals should reinforce international factors including global distribution with visibility to be considered as reputable international journals.

The more importance of international collaboration has increased, the more studies on statues of international collaboration are increasing. However, few studies have attempted to identify the international collaboration. This article aims at a multidirectional characterization of the international collaboration in the field of Computer Science by analysis of articles published in the SCOPUS database. We applied Probabilistic Affinity Index(PAI) and Indicator of Collaboration Strength(ICS) for measuring the intensity of scientific collaboration among countries, and index of Incremental Citation Impact(ICI) for measuring the quality of international collaboration. These analyses identify the trends of international collaboration in the field of Computer Science and it's effect by nation.

This study is a comparative analysis of R&D performance and research collaboration relationship among ten ocean research institutes in the Republic of Korea and foreign nations through analyzing SCI publications from 2008 to 2012. The result indicated that SIO, WHOI, and NOC had the highest number of publications, while research institutes in East Asian nations including NFRDI, KIOST, IOCAS, and JAMSTEC had the notable growth in publication. In terms of number of publication per researcher, SIO, WHOI, and NOC had relatively high number. In terms of publication per research budget (1 billion KRW), number of publication was high in the order of IOCAS, NOC, GEOMAR, SIO. The number of Citations Per Publications (CPP) was high among WHOI, SIO, NOC, GEOMAR, JAMSTEC, and IFREMER, which are North American, European and Japanese institutes. The average Impact Factor (IF) of journal submission per publication for IFREMER, KIOST and JAMSTEC was relatively increasing, while the number was fluctuating in other institutes. The analysis of research collaboration among institutes around the globe showed that the collaboration in Asia was relatively closed, whereas it was more open in Europe. In the case of Europe and Asia, higher number of research collaboration among nations also increased the quality of submitted articles.

Recently collaboration network is generated to find out experts in their field as potential collaborators in health care sector. In this paper, the co-author network of a National Cancer Center researcher was generated for identifying each researcher's role and collaborative research pattern. The co-author network of 2,437 authors was extracted from 1,194 SCI(E) publications from 2000 to 2010 and author's role was analyzed by author's centrality value. Centrality reflecting only the number of papers and centrality weighted by the paper number, impact factor, and authorship contribution was evaluated. On the comparison with simple degree centrality value and the weighted degree centrality, difference of value was statistically significant(t=11.66, p=0.00). Co-author network considering various variables of the paper provides more objective figure of researcher's role. This suggests that co-author network could be more effective in identifying potential collaborators.

Rapid globalization process is applying to Science field in Korea. Until now, most researches and government's announcement used to examine the scientific level of Korea by using the number of publications in the SCI Journals. I investigate other aspects of the scientific globalization: a scientific collaboration trend, participations of foreign researchers, and the national level of collaboration networks. There are increasing patterns in collaboration and foreign researchers' participation, and the Impact Factors of the Journals were preceded by inflating trend in the participations of foreign researchers. Also, the breadth and the density are different from each science fields in the national level of collaboration networks. These findings are related to the process of globalization in the Korean science journals and the science fields.
