The purpose of this research is to accomplish the goal of science education based in the seventh science course of study by suggesting the plan for development of executable method in the learning process of Earth Science education and establishing a practical model to evaluate its achievement. Furthermore, the idea of this research is to recognize a way of using and consideration at practical use of the model. Since the purpose of the educational evaluation is to maximize the efficiency of school studying, there are some negative aspects in our current method of evaluation to achieve the purpose. New system has been introduced into the educational evaluation to resolve such a critical issue. Despite some positive aspects in the system, it could not be escaped from the multiple choice and pens examination. This could be caused by in various limitations, especially the insufficiency of teachers' awareness and the data about the Performance assessment. This research is to develop and use the practical model for the Performance assessment in consideration of current educational circumstances of Junior and High school. The model of the Performance assessment in this research is to sufficiently evaluate student's ability and skill in the learning process of Earth Science education. Hence, it is dedicated to the education for human being and improve quality in the learning process of the Earth Science education among the modern society, which is characterized globalization and information.

This thesis presents the methods and tool development of performance assessment as final stage for information literacy instruction of teacher-librarians. The evaluation is an important part in information literacy instruction of teacher-librarians in the school libraries. But until now, there is little research on evaluation methodologies in the instructional activities of teacher-librarians. There is only evaluation domain presented in the primary and secondary 'Information and the Library' curriculum. To develop an evaluation model as a base for measuring performance assessment related to teacher-librarians is important. The goal of this thesis is to provide teacher-librarians with basic principles to develop many kinds of performance assessment tools in their own instructional activities.

Development of social overhead capital (SOC) requires huge national finance, and performance issues such as cost-efficiency, safety, and environment have been constantly raised. However, currently each construction client has limited access to its own projects' performance without analytic methodology for industry-level comparisons and benchmarking for improvement. To overcome this problem, this study proposes a comprehensive performance analysis framework for post-evaluation of large-scale construction projects. To this end, this study performed a case study of advanced countries (the U.S., the U.K. and Japan) and consultation with related experts to develop a tailored performance analysis framework for the Post- Construction Evaluation and Management system in Korea. The developed framework covers three categories (project performance, project efficiency, and ripple effect), nine areas (cost, schedule, change, safety, quality, demand, benefit-cost ratio, civil complaint, and defect), and 31 detailed metrics. Using industry-level project performance database and statistical techniques, the proposed framework can be used not only to diagnose excellent and unsatisfactory performance areas for completed construction projects, but also to provide reference data for future similar projects. This study can contribute to the improvement of clients' performance management practices and effectiveness of construction projects.

To solve environmental problems, research and efforts are required to reduce leather waste that is generated in large quantities during the leather manufacturing process. Leatherboard is a plate-like material that is made by crushing leather waste, such as trimming or shaving scraps and mixing fibers, pulp, rubber, and adhesives. The aim of this study is to provide basic data on the localization of leatherboard manufacturing technology for outsoles, which are increasingly in demand due to their excellent performance and price competitiveness. Interviews with experts and related organizations were conducted to investigate the related global technology trends. Also, the performance of three products that can be used as reference materials were evaluated and compared. As part of the research and efforts to reduce the amount of leather waste generated, high-performance materials using leather waste were developed and commercialized by major western companies. In Korea, various efforts have been made since 2000, and some companies have produced leatherboard for interior uses. However, the amount of waste recycled relative to that generated is not large due to the limited demand. Natural leather soles perform better than leatherboard soles in all evaluation aspects. In the case of leatherboard, performance varied by manufacturer. German products showed flexibility resistance and dimensional stability, thereby meeting performance requirements. However, abrasion resistance and cleavage resistance were slightly below the required performance standards, and research and development is needed to improve performance in those areas. Currently, it is impossible to evaluate the performance of domestic products due to underdevelopment. However, if the development of process technology continues based on the performance evaluation results of the best leatherboard in the shoe industry, materials for outsoles will be able to be produced domestically with prices competitiveness while realizing natural leather materials performance to some extent.
