The purpose of this study was to examine whether the new introduction of elementary science experiment specialist is appropriate under the current situation of serious emphasis of the importance in science experiments in elementary science in Korea. For this study, the survey items were developed twice through the preliminary study. The results show that most elementary teachers consider the importance of experiment in elementary science and the critical role of science experiments to increase students' curiosity and scientific understanding. About 80% of the teachers stressed the professionalism in elementary science. Although 65% of the teachers believed their having basic professionalism, 53% of them appealed the difficulty in teaching science experiments to students. Nevertheless, 67.5% of the teachers opposed to the idea of teaching elementary science in separation between experiment and theory in science, and only 8% of them agreed the idea of induction or adoption of the college graduates majoring in science and engineering, or holding the secondary teacher's certificate. Further, over 60% of the teachers responded no necessity of inducing the new policy of elementary science specialist. Many numbers of teachers revealed their serious worries about the new policy because of their past experience to suffer from the side effects of inducing the teachers with secondary teacher certificate to the elementary school. In particular, they also made a proposal to make a good use of the current system of exclusive elementary science teacher in Korea. The educational implication and suggestions for policy making were discussed.

The aim of this research is to develop a clothing and textiles studio course for preservice home economics teachers applying principles of Project-Based Learning (PBL) and maker education to equip future teachers with the ability to nurture creativity among adolescents. The studio course was developed in the following stages: analysis, design, development, implementation, and evaluation. We concluded that the resulting course met the following objectives extracted from the 2015 revised curriculum of home economics subjects: to promote creative and environmentally-friendly fashion design and styling abilities, gain the ability to use makerspace tools, understand flat pattern making and sewing processes, and develop creative thinking, aesthetic sense, and communication skills. Furthermore, the educational effects of PBL and maker education were confirmed through student comments on the course. Students mentioned the practicality of the material in their actual lives along with their enhanced integration of the subject material, self-directedness, aesthetic sense, ability to learn through trial and error, collaboration and communication, and sharing. Based on results from the implementation and evaluation stages, a clothing and textiles studio course should include the following modules: introduction of terms and tools, submission and sharing of clothing reformation and upcycling techniques, introduction to hand sewing, pouch making, heat-transfer printing, 3D printing, mask making, hat making, vest making, and the final team project on fashion styling. It is important for instructors to provide detailed guidelines on selecting personas for styling, looking for available materials, and selecting materials online.

A small-scale thermoelectric cooling system was built in an effort to enhance the performance of the refrigeration system by utilizing the water-cooled jacket which was attached on the hot side of the thermoelectric module. Considered design parameters for the water-cooled jacket included the geometry of the flow passage inside the jacket and the flow rate of cooling water. The higher flow rate of cooling water in the jacket resulted in a better performance of the refrigeration system. The introduction of geometrical complexity of the cooling water flow passage to the cooling jacket also showed significant improvement on the performance of the thermoelectric refrigeration system such as the cooling capacity and the COP of the refrigeration system.
