  • The purpose of this study is to investigate 1) the types of knowledge students ask for in their reading comprehension of science textbooks using an online annotation system, 2) the accuracy of the knowledge provided by the students to their peers, 3) the frequency of knowledge sharing behaviors, 4) the evaluation of the effect of collaborative reading, and 5) the trust among peers as knowledge sharers. Questions made by 241 students in the second grade of middle school using an online annotation system in two chapters of the science textbook were analyzed using Bloom's revised taxonomy and their answers were grouped according to five accuracy categories. Also, questionnaires for the evaluation of the effectiveness of collaborative reading comprehension and of trust among the students were used. The students asked their peers 'understanding questions' which comprised almost 80% of the total questions they made and were similar with individual metacognitive strategies for reading comprehension. Of the total threads, 71% has scientifically correct threads shared by the students. The frequency of the knowledge sharing behaviors was high but this was affected by the rewards (point system). Students evaluated that collaborative reading comprehension conducted through an online annotation system were helpful in their learning. In addition, the ratio of students trusting their peers who did the knowledge sharing is over 80%. This study shows that when students use an online annotation system, they can fill one another's cognitive gaps in the reading process by sharing knowledge. Also, collaborative reading using an online annotation system has proved that cognitive individualization is possible through sharing knowledge interactively and dynamically, unlike reading hard copies of textbooks which are a one way information transfer.

  • This paper analyzes the strategic planning process of NASA (National Aeronautics and Space Administration) including its center, GSFC (Goddard Space Flight Center) in the framework of strategic planning in publicly funded R&D organizations. To construct this framework, theories have been considered mainly focused on strategic management and planning, its application on public sector, and characteristics of R&D activities. As a result, the framework could be set up in accordance with the process of strategic planning. Also, as a case study, we explored the practice of strategic planning process and organizational implementation of NASA and GSFC. During the analysis on the strategic process of NASA and GSFC, we could draw some lessons out as follows: First, we should consider the differences between private and public sectors when we establish strategic planning in public sector. Second, the stakeholder analysis should be involved in setting the mission, goals, and strategies of an organization. Third, it is necessary to identify and assess the socio-economic effects or public benefits by R&D programs of the organization and use the feedback on its goal. Fourth, to implement strategic planning effectively, planning process should be closely integrated with the management process such as setting goals, securing budgets, and evaluating the organization. Conclusively, the analysis on NASA and GSFC contribute to implementing strategic planning in publicly funded R&D organizations by providing the appropriately modified framework. As an extension of this study, more deliberate analysis on various practices of strategic planning and performance indicators should be followed.

  • This study aimed to develop an e-PBL program for high school students using COVID-19 related data and to investigate the impact of the developed program on students' science core competencies. For this, the e-PBL program was developed in consideration of the characteristics of learners and e-PBL, and a science core competency analysis framework. The program was applied to 26 general high school life science club students. Test for science department core competency was conducted before and after class by questionnaires and their conversation data during class was collected and analyzed by the framework. As a result of the study, the developed program was effective in improving five science core competencies. In the results of the analysis of the science core competency questionnaire, there were significant effects on scientific thinking ability, scientific inquiry ability and scientific problem solving ability. Unlike in the results of the questionnaires, the five sciences department core competencies appeared evenly in student discourse analysis. Among them, scientific communication ability and scientific participation and lifelong learning ability did not show significant results in the questionnaire, but in the discourse analysis results. Both abilities were the most evenly displayed competencies through the program stages. Through the study, we expect that the program is possibles to be useful instructional material to make high school students increase science core competencies.

  • An MRA is considered to be an important policy tool within the WTO for overcoming technical barriers to trade. A number of studies on the economic impact of MRAs have demonstrated their positive economic effects. However, no studies have been conducted on MRAs in the pharmaceutical industry since analysis has been limited to industries as a whole or certain industries where some data were accumulated. Therefore, this paper analyzed the economic impact of MRAs for GMP inspection exemption in the pharmaceutical industry through the Conditional Valuation Method (CVM), a valuation technique for non-market goods. Pharmaceutical companies were asked whether or not they were willing to pay for the Korea-EFTA MRA through double-bounded dichotomous choice (DBDC) questions. The final WTP was estimated using the utility difference model developed by Hanemann (1984). As a result, annual economic effects on the pharmaceutical industry were estimated to be between KRW7.03 billion to KRW15.8 billion.

  • Recently, EA has been introduced in the Korean government as a tool for improving both IT management and IT investment. However, EA has been superficially used at the conceptual level without any efforts for facilitating it. As a result, it seems that any substantial outcomes from using EA could be hardly realized. This study suggests EA Service Model as a framework for facilitating the use of EA and then generating benefits. The purpose of EA Service Model is to provide a framework with which information and data can be linked, interconnected and shared in the whole process of IT management. It is expected that EA Service Model will possibly make a contribution to improving IT management. Empirical Analysis shows that key factors of EA Service Model make significant effects on improving the IT management, proving practical value and the validity of the model.

  • The Laplacian operator is usually used as a regularization operator which may be used as any differential operator in the regularization iterative restoration. In this paper, several kinds of differential operator and 1-H operator that has been used in our lab as well, as a regularization operator, were compared with each other. In the restoration of noisy motion-blurred images, 1-H operator worked better than Laplacian operator in flat region, but in the edge the Laplacian operator operated better. For noisy gaussian-blurred image, 1-H operator worked better in the edge, while in flat region the Laplacian operator resulted better. In regularization, smoothing the noise and resorting the edges should be considered at the same time, so the regions divided into the flat, the middle, and the detailed, which were processed in separate and compared their MSE. Laplacian and 1-H operator showed to be suitable as the regularization operator, while the other differential operators appeared to be diverged as iterations proceeded.
