The Research and Education (R&E) program was a year-long, apprenticeship and research-based program that was guided by mentors who are scientists or science teachers. The objective of the R&E program was to help scientifically gifted students in Korea Science Academy (KSA) and Science High Schools (SHS) to enhance abilities in creative thinking, scientific inquiry, problem solving, positive attitude towards scientists, and promoting cooperative research and interests in science and technology. In this study, the impact of the R&E program on the goals of 182 gifted college students in KAIST was evaluated using Likert-type items and multiple-choice method approach that provided a more comprehensive evaluation of the program's impact on science attitudes, creative thinking, scientific inquiry, and interests in science and technology. The results indicated a positive impact on cooperative research, gaining knowledge on the research topic, attitude towards scientists, interest in science and technology, scientific inquiry, and creative thinking in that order. There were rather remarkable and meaningful differences in science inquiry (p<.05), and scientific knowledge (p<.01), between the two groups of KAIST freshmen who came from SHS and KSA in 2006. Implications for science apprenticeship or a research-based mentorship program and their respective evaluations are also discussed.

This study presents a possibility of intensification of fine dust mass concentration due to the complex urban structure using data mining technique and clustering analysis. The data mining technique showed no significant correlation between fine dust concentration and regional-use public urban data over Seoul. However, clustering analysis based on nationwide-use public data showed that building heights (floors) have a strong correlation particularly with PM₁₀. The modeling analyses using the single canopy model and the micro-atmospheric modeling program (ENVI-Met. 4) conducted that the controlled atmospheric convection in urban area leaded to the congested flow pattern depending on the building along the distribution and height. The complex structure of urban building controls convective activity resulted in stagnation condition and fine dust increase near the surface. Consequently, the residual effect through the changes in the thermal environment caused by the shape and structure of the urban buildings must be considered in the fine dust distribution. It is notable that the atmospheric congestion may be misidentified as an important implications for providing information about the residual probability of fine dust mass concentration in the complex urban area.

This study investigated the relationships of the self-regulated learning strategies used in both science and English classes and motivation to academic performance of science-gifted high school students. Participants of this study were 144 freshmen of Korea Science Academy It was found out that the use of self-regulation learning strategies and motivation exerts differential influence on the academic performance of science-gifted students, depending on the subjects they study. Results showed that they used more vigorously in science class those self-regulated strategies which consist of cognition, metacognition, and resource management strategies than in English class. In addition, their motivation level in science class was significantly higher than that in English class. Self-regulated strategies did not explain any variance in physics GPA. Task value among the motivation variables accounted for 2 percent of variance in physics GPA. Metacognition and time and study environment variables explained 8 percent and 15 percent of variance in English GPA, respectively. Self-efficacy in motivation accounted for 30 percent of variance in English GPA, These results were discussed in the light of instruction for science-gifted high students.
