  • The purpose of this study was to develope an Inquiry-Based Environmental Education Program for Elementary School Students by Using DO meter based on the theory of the inquiry-based environmental education. The developed program consisted of 5 constituents of Environmental Studies for the Environmental Education (ESEE) and was applied to the 6th grade students of elementary school. The inquiry activities have been conducted around Gigyechon stream in Pohang city where the school was located. The evaluation form to evaluate the environmental education programs in the perspective of the Inquiry-Based Environmental Education was developed and used to evaluate after applying the developed programs. As a result, it was known that the developed programs have been well constructed and this program would help fostering the environmental understanding of the world. And also the inquiry-based environmental education was suitable for the environmental education targeting the elementary school students. This study has a significance in the perspective that the concept and the theory of inquiry-based environmental education has been realized into the program suitable for the elementary school students and that the new direction of the environmental education for the elementary school has been suggested. In addition, the developed evaluation form to assess the effectiveness of the program is expected to be helpful for the future studies related to development of the inquiry-based environmental education programs.

  • The purpose of this research is to apply and evaluate the Water Environmental Education Program Using Streams(WEES) to pre-service teachers. WEES is developed to help the teachers increase their professionalism of incorporating a local environment into their inquiry teaching. The subjects of the study include the juniors of the Environmental Education Major at the Korea National University of Education. For the purpose this study, educational criticism about WEES was performed. The subject students were observed throughout the program application, after which a survey and in-depth interviews were carried out. As a result, the implementation elements and content organization of the WEES were found to be implemented in the application process in a satisfying level. In the content organization of the program, the preliminary preparation, visual assessment, and inquiry planning were organically connected with each other for inquiry purposes. The Intrinsic value of environmental education was also demonstrated in the implementation elements and content organization. Overall, the stream turned out to have a great value of environmental education and a potential as a place and material for environmental education. The great significance of the study can be found in that WEES took into account not only the characteristics of the ENVISION based on the watershed concept, but also the situations of Korea's environmental education and exploration from the perspective of environmental studies.

  • For developing a new embedded system, an application program/an emulator and a compiler are developed simultaneously. In order to provide the optimal performance of all system components, local optimization should be carried out for the developing process. For this purpose, if a source-level performance analyzer is developed, it is possible to optimize the application program's source code by the performance evaluation. In general, the performance of an application program is determined in the loop iterations. The Intermediate Representation (IR) code generator generates IR code from the source code, and evaluates the execution time with the instructions in the intermediate representation code. If the source code is improved based on the evaluated result, better results can be obtained in the final application code. This study describes the source-level performance analyzer that can be used during the simultaneous development of the new embedded system and its application programs. The performance analyzer makes it possible to more quickly optimize the performance of the new embedded system.
