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.

Although the functional ingredient has been evaluated by the Korea Food and Drug Administration (KFDA) based on scientific evidence, the levels of scientific evidence and consistency of the results might vary according to emerging data. Therefore, periodic re-evaluation may be needed for some functional ingredients. In this study, we re-evaluated scientific evidence for the antioxidant activity of coenzyme Q10 as a functional ingredient in health functional food. Literature searches were conducted using the Medline and Cochrane, KISS, and IBIDS databases for the years 1955-2010 with the search term of coenzyme Q10 in combination with antioxidant. The search was limited to human studies published in Korean, English, and Japanese. Using the KFDA's evidence based evaluation system for scientific evaluation of health claims, 33 human studies were identified and reviewed in order to evaluate the strength of the evidence supporting a relation between coenzyme Q10 and antioxidant activity. Among 33 studies, significant effects for antioxidant activities were reported in 22 studies and their daily intake amount was 60 to 300 mg. Based on this systematic review, we concluded that there was possible evidence to support a relation between coenzyme Q10 intake and antioxidant activities. However, because inconsistent results have recently been reported, future studies should be monitored.

This study aims to empirically estimate distributed lag effects of expenditure by type of R&D on scientific publication in the national R&D program. To analyze the lag structure between them, we used a dataset comprised of panel data from 104 technologies categorized by 6T (IT, BT, NT, ST, ET, CT) from 2007 to 2014, and employed multiple regression analysis based on the polynomial distributed lag model. This is because it is highly likely to emerge multicollinearity, if a distributed lag model without special restrictions is applied to multiple regression analysis. The main results are as follows. In the case of basic research, its lag effects are relatively evenly distributed during four years. On the other hand, the applied research and experimental development have distributed lag effects for three years and two years respectively. Therefore, when it comes to analyzing performance of scientific publication, it is necessary to be performed with characteristics of the time lag by type of R&D.

Korea has begun institutional education for the gifted since 2002. It has quantitatively expanded, but needs rather qualitative growth. The purpose of this study is investigating a case of scientific education for the gifted in Russia. Three principal of Russian science academy, one educational psychologist, and one education-government official had in-depth interviews for this study. All data from interviews were carefully analyzed. The Science education for the gifted in Russia gives us full assurance that students should reveal their potential ability with the specialized program in school. The Russian run various, particular academies because they try to search for potential ability in manifold areas. The people in charge of scientific education in Korea should make an effort to seek for varied routes in the way of searching for hidden originality and potential ability.

The cultivation of scientific literacy in recent science education can be improved by experiencing and understanding scientific inquiry by which scientific knowledge is formed. The National Research Council(NRC) released the Next Generation Science Standards (NGSS) including 8 practices of science that help students experience scientists' inquiry and subdividing achievement standards to perform 8 practices of science into by grade clusters. This study was intended to examine science inquiry activities included in 4 high school chemistry II textbooks developed by the 2009 revised curriculum using the 8 scientific practices and their achievement standards for 9th-12th grade. The science inquiry activities and the science practices included in the 4 textbooks were 173 and 678. The science practices included in the inquiry activities of 4 textbooks included the most ‘analyzing and interpreting data.’ The ‘engaging in argument from evidence’, ‘Obtaining, Evaluating, and Communicating Information’ were less than other practices. The ‘asking questions and defining problem’ and ‘developing and using models’ were not nearly included in the 4 high school chemistry II textbooks.

A scientific model refers to a conceptual system that can describe, explain, and predict a particular physical phenomenon. The co-construction of the scientific model is attracting attention as a new teaching and learning strategy in the field of science education and various studies. The evaluation and modification of models compared with the predicted models of data from the real world is the core of modeling strategy. However, there were only a limited data provided by the teacher in many studies of modeling comparing the students' predictions of their own models. Most of the students were not given the opportunity to evaluate the suitability of the model with the data in the real world. The purpose of this study was to develop a scientific model co-construction program that can evaluate the model by directly comparing the predicted models with the observed data from the real world. Through a collaborative discussion between teachers and researchers for 6 months, a 5-session scientific model co-construction program on the subject 'image formation by convex lenses' for second grade middle school students was developed. Eighty (80) students in 3 classes and a science teacher with 20 years of service from general public co-educational middle school in Gyeonggi-do participated in this 2-week program. After the class, students were asked about the helpfulness and difficulty of the class, and whether they would like to recommend this class to a friend. After the class, 95.8% of the students constructed the scientific model more than the model using the construction rule. Students had difficulties to identify principles or understand their friends, but the result showed that they could understand through model evaluation experiment. 92.5% of the students said that they would be more than willing to recommend this program to their friends. It is expected that the developed program will be applied to the school and contribute to the improvement of students' modeling ability and co-construction ability.

Meteorological data contains observation and numerical weather prediction model output data. The computerized analysis and visualization of meteorological data often requires very high computing capability due to the large size and complex structure of the data. Because the meteorological data is frequently formed in multi-variables, 3-dimensional and time-series form, it is very important to visualize and analyze the data in 3D spatial domain in order to get more understanding about the meteorological phenomena. In this research, we developed interactive 3-dimensional visualization techniques for visualizing meteorological data on a PC environment such as volume rendering, iso-surface rendering or stream line. The visualization techniques developed in this research are expected to be effectively used as basic technologies not only for deeper understanding and more exact prediction about meteorological environments but also for scientific and spatial data visualization research in any field from which three dimensional data comes out such as oceanography, earth science, and aeronautical engineering.
