  • The purpose of this study is to analyze science fields and content elements of the science reports in a web portal site of Republic of Korea in view of scientific literacy. The main results of the analysis on the 679 reports sampled in a year are as follows. First, 506 reports in 46 fields were identified. Reports about technology and earth science occupies 16% respectively, and life science occupies 13%, medical science 4%, chemistry, company, others 3% and physics 1%. Almost reports show technology as associate field. Second, the frequency rate of reports including scientific literacy content elements is 52%. Reports related to 'physics' and 'chemistry' as dominant fields show relatively high rate in scientific literacy elements. The element, 'social context' is included in about 96% of the reports. Both 'data and statistics' and 'application' show relatively low rate and large gaps according to dominant fields. A few concluding remarks and proposals follow from these results. First, as almost science reports show the nature of integrated science, scientific literacy acquisition through science reports in internet requires the integrated scientific view. Especially most science reports includes the contents related to technology or medical science, so the point of view in the science-technological literacy is required. Second, the scientific literacy content elements in reports show various rates according to dominant fields. Therefore, science reports need to complement the deficient content elements to carry out the role of science reports as scientific literacy sources.

  • Given the difference in research performance in various scientific fields, this study aims to weight and valuate current indicators used for evaluation of scientific productions (publications), in order to adjust these indicators in comparison to each other and make possible a more precise evaluation of scientific productions. This is a scientometrics study using documentary, evaluative, and survey techniques. The statistical population consisted of 106 top Iranian researchers, scientists, and scientific and research managers. Then their research résumé information was gathered and analyzed based on research questions. In order to compare values, the data gathered from research production performance of the population was weighted using Shannon entropy method. Also, the weights of each scientific production importance according to expert opinions (extracted from other works) was analyzed and after adjustment the final weight of each scientific production was determined. A pairwise matrix was used in order to determine the ratios. According to the results, in the area of engineering sciences, patents (0.142) in the area of science, international articles (0.074) in the area of humanities and social sciences, books (0.174), and in the area of medical sciences, international articles (0.111) had the highest weight compared to other information formats. By dividing the weights for each type of publication, the value of each scientific production compared to other scientific productions in the same field and productions of other fields was calculated. Validation of the results in the studied population resulted in very high credibility for all investigated indicators in all four fields. By using these values and normalized ratios of publication indicators it is possible to achieve precise and adjusted results, making it possible to feasibly use these results in realistic policy making.

  • This study identifies the interdisciplinary structures of 8 scientific disciplines in science and technology using the data from journal citations and web links, and compares the interdisciplinarity among these scientific disciplines. The interdisciplinarity refers to interdisciplinary connections among scientific fields and the degree of interdisciplinarity is measured by the number of associated fields and the rate of self-citation. A re-arranged classification scheme for science and technology was adopted to identify subject categories of journals and web pages. Web link analysis revealed a few additional interdisciplinary connections that were not identified by the journal citation analysis, thus demonstrating that it is useful means of investigating the interdisciplinarity of scientific fields. Besides, in most of the cases the interdisciplinarity of the engineering fields were found greater than that of the fields in natural sciences in both analyses.

  • Basic research have contributed to technological growth or economic growth in U.S. Specially recent studies say that universities also contribute to economic development through scientific activities like science research, education, technology transfers. But we can not assure whether scientific knowledge was connected to real technology or economic performance, and it is difficult to figure out the effect of scientific output. "What is the exact performance of scientific knowledge?" It is still obscure. In this context, this paper analyzes characteristics of the linkage of science and technology. Data are U.S. R&D expenditure, scientific articles, citation of articles in U.S. patents by fields and sectors. As a result, university sector has the most weight of the linkage of science and technology. But, in relative connection rate analysis, industrial sector's is stronger than any other sectors. In the field analysis, linkage of science and technology is very strong in Chemistry, Physics, Biological sciences fields. And recently the linkage was increased in the fields of Computer science, Agricultural science, Engineering. Finally, this paper supports funding policy or estimation policy of government to product of scientific knowledge. University sector is still important because it has the most weight of the linkage. Scientific knowledge of industrial sector is also important. The connection rate of industrial science is the strongest in all sectors. And this research classify the R&D type by science fields. Considering the differences of science fields is needed to product science knowledge effectively.

  • 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.

  • The inability of the management information systems (MIS) field to progress as a scientific discipline has been attributed to the lack of systematic research and a cumulative tradition, an identity crisis, and the poverty of scientism. While research on the status of MIS is very important in order to enhance the field as a scientific discipline, few have investigated this issue. Following Thomas Kuhn's idea of paradigm, this paper studies other fields to investigate when they progressed, when they did not, and why. After research paradigm was broken down into technology-push and demand-pull types, a model on the science life cycle was developed in an effort to explain the path how a science has progressed. A test of this model in the fields of physics and chemistry with an old historial background reveals that the scientific progress in the area of demand-pull is more desirable if this progress turns out to be in the right direction. An application of the model to the MIS field shows that the research paradigm in this field is mainly of technology-push. In order to shift this paradigm toward the demand-pull area, this paper suggests the research on the relationship among MIS subfields and the adoption of appropriate reference disciplines.

  • Developments in the emerging field of Computational Fluid Dynamics(CFD), which is made possible by the supercomputer technologies, introduce a new problem of analysing the massive amount of output produced. This problem is common to fields of computational science and engineering. Scientific visualization is to solve this problem by applying advanced technologies of computer graphics. Methods of scientific visualization are studded to visualize calculated flow fields. Different methods of scientific visualization has been surveyed, analysed and compared to select one method, iso-surface. Methods of constructing iso-surfaces from a 3-D data set have been studied. A new algorithm for constructing iso-surfaces has been developed. The algorithm can be classified as one of surface tiling methods. To develope a portable visualization system the international standard PHIGS PLUS and its implementation on X-Window system, PEX, have been selected as the development environment. A prototype of visualization system has been developed. The developed visualization system has been tried to visualize several well-known flow fields.
