  • The purpose of this study was to investigate the elaboration strategy associated with multimedia learning for children. Main subjects of this study, which were 157 eight-, 150 ten- and 152 twelve-year-old children(total: 459). As a result, the elaboration strategy could find the facts to be effective to twelve-year-old children. And the elaboration strategy at cognitive style was not significant. We would suggest that the age is a significant variable to apply the elaboration strategy in multimedia learning.

  • The effects of pH on the cell growth, the elaboration of pullulan, and the morphology of Aureobasidium pullulans IFO 4464 were examined. A. pulluans grew in yeast-like form at constant pH7.5 and in mycelial form at constant pH2.5. At the both pH conditions, the elaboration of pullulan was very low, about 6.0~6.5g/l. The mixture of yeast-like form and mycelial form of cells was found at the constant pH4.5, at which condition, the elaboration of pullulan was high, about 24.5g/l. The pH shift experimemts showed that the specific production rates of pullulan were 0.048($hr^{-1}$)for the mycelial form and 0.058($hr^{-1}$)for the yeast like form, which indicated that the yeast-like form has the similar, only slightly higher, biosynthetic activity of pullulan to the mycelial form at pH4.5 and the pH of culture broth is more important factor for the elaboration of pullulan than the morphology of A. pullulans.

  • This study investigated a utilization deficiency phase in the situation of children's acquiring mnemonic strategies in which children successfully execute a strategy but the strategy does not facilitate memory performance. This study examined spontaneous acquisition of elaboration strategy among 5th grade children in the learning of noun pairs for 5 sessions. Participants were tested in memory task using different list of word pairs in each session. Results showed that children increased the use of elaboration strategy significantly in 5 sessions but they did not gain benefit in recall. When the word pairs were associated, the use of elaboration strategy was significantly increased but children did not gain benefit in recall. This results were discussed in terms of utilization deficiency.

  • VHDL simulation requires both analysis and elaboration processes. Reducing the time taken by these processes shorten design cycles. We propose an incremental analysis and elaboration algorithm for VHDL, which minimizes the number of design units to be re-analyzed and re-elaborated after an incremental change, thereby reducing the desing cycle time. Experimental results show about four times performance improvement in analysis and 1.25 times in elaboration over the conventional method.

  • The contents of 'Nutrition and Diet for Adolescents' in the 12 technology and home economics middle school 1st grade textbooks are analyzed based on the elaboration theory. The elaboration theory is the lecture strategy with 7 essential elements, proposed by Reigeluth. The elaboration strategies shown in 'Nutrition of Adolescents' and 'Diet for Adolescents' are all the same in 12 books, the conceptual elaboration, and the process elaboration, respectively. On the other hand, the elaboration strategies shown in 'Diet and Dietary Habit for Adolescents Nutrition Issues' and 'Proper Eating Habit and Nutrition Issues' are different depend upon the textbooks, all 3 conceptual, theoretical, and process elaborations strategies are shown. The element of pro study is presented by study objective, opening the thinking, and looking back. The summarizer is presented in all 11 but 1 textbooks by various activities and data. On the other hand, the element of analogy has the lowest implementation rate, only 3 among the 12 textbooks implement the analogy. The cognitive-strategy activator and learner control are shown in all 12 textbooks, mostly by data. Implementation of more activities and more analogies might be helpful to the students' participation and understanding the contents of 'Nutrition and Diet for Adolescents'.

  • The purpose of this study was to analyze science gifted students' creativity subscales. The Torrance Tests of Creativity Thinking(TTCT) were administered to 385 science gifted students from 2006 to 2010 for this study. The results were as follows: First, fluency correlated highly with originality, and elaboration also highly correlated with abstractness of titles. All of the correlation coefficients of the variables with resistance to premature closure were high. Second, the elaboration scores were higher than other variables, and abstractness of titles scores and resistance to premature closure scores were lower than other variables regardless of regions and gender. There was no significant difference according to regions, but the elaboration scores of female science gifted students were significantly higher than male science gifted students'. The fluency scores were the most influential factor to the creativity index among the creativity subscale scores. Third, after completing the science gifted program, students showed significant difference in fluency scores, abstractness of titles scores, and resistance to premature closure scores; however, they showed no difference in originality scores and elaboration scores.

  • The purpose of this study was to identify the preferable learning strategies in science learning and to find out the relationship between these strategies and scientific achievement of students in the secondary school. The learning strategies were tested with two categories, self-focused and work-focused learning. The four types of learning strategies in science learning were analyzed, and they were named to organization, monitoring, elaboration and memorization strategies, which were defined by GSSS test. In the self-focused learning, the organization and monitoring strategies were preferred to the elaboration and memorization strategies. Middle school students had a preference for memorization strategy (p=0.000), whereas high school students had a preference for monitoring strategy (p=0.015). In the case of organization strategy, female groups were preferable to male groups (p=0.027). In the second form of learning types, work-focused learning, the memorization strategy was the same preference as organization and monitoring strategies in the secondary school students, especially the male groups of high school students. The preference of elaboration strategy was relative lower compared with that of self-focused learning type. Middle school students had a preference for monitoring strategy (p=0.001), whereas high school students had a preference for elaboration strategy (p=0.001). The difference of each preference between male and female groups was not shown. From the analysis of correlation between learning strategy and scientific achievement, it showed that the monitoring strategy was commonly correlated with scientific achievement. In the self-focused learning, elaboration and organization strategies were correlated with scientific achievement in high school students (p<0.05). In the work-focused learning, memorization strategy was correlated with scientific achievement in middle school students, especially in male groups (p<0.05).

  • One area where research is especially needed is their elaboration process and how they elaborate their idea as a group in a mathematical board game re-creation project. In this research, this process was named 'Mathematical Elaboration Process'. The purpose of this research is to understand how the gifted children elaborate their idea in a small group, and which idea can be chosen for a new board game when they are exposed to a project for making new mathematical board games using the what-if-not strategy. One of the gifted children's classes was chosen in which there were twenty students, and the class was composed of four groups in an elementary school in Korea. The researcher presented a series of re-creation game projects to them during the course of five weeks. To interpret their process of elaborating, the communication of the gifted students was recorded and transcribed. Students' elaboration processes were constructed through the interaction of both the mathematical route and the non-mathematical route. In the mathematical route, there were three routes; favorable thoughts, unfavorable thoughts and a neutral route. Favorable thoughts was concluded as 'Accepting', unfavorable thoughts resulted in 'Rejecting', and finally, the neutral route lead to a 'non-mathematical route'. Mainly, in a mathematical route, the reason of accepting the rule was mathematical thinking and logical reasons. The gifted children also show four categorized non-mathematical reactions when they re-created a mathematical board game; Inconsistency, Liking, Social Proof and Authority.

  • The purpose of this study is to elaborate the request for proposal (RFP) for the localization parts development support project of core parts carried out by the Defense Agency for Technology and Quality. The RFP is the most important document throughout the localization parts project, including project announcement and developer selection, design and test of the development product, final evaluation, and standardization of the project. However, if the RFP is not established at the beginning of the project, there is an increased risk of business failure due to frequent changes by various reasons. In this study, we recognized the necessity of elaboration of RFP and applied the AHP method for quantitative elaboration. Eight requirements of the RFP related to the mechanical/electrical performance of localized development products and three elaboration methods for each requirement were designed in a hierarchical structure, and each weight was calculated by applying the 5-point scale AHP method. The AHP survey was conducted with 20 developers participating in the localization parts project, and the consistency ratio of the AHP survey result was less than 0.1. The elaboration method with the highest value among the calculated weights is classified, and the analysis results and future research directions of the elaboration method are presented.
