According to trends in scientific technical competition, many countries around the world are interested in and focused on the STEAM integrated education. By observing the fact that the goal of our country's science education is to cultivate creative workers who have scientific knowledge, the need for STEAM integrated education cannot be denied. Therefore, the purpose of this study was to develop the STEAM integrated program focused on themes that considered activities and interest in the grade 6 science subject in order to identify its influence on the creativity and interest levels of elementary students. The STEAM integrated education program in this study was developed so that it can be applied as a unit review or reinforcement activities in the closing activities per unit in grade 6. The focus was placed on heightening students' creativity and interest in science subject learning through a program focused on activities per theme. As a result of applying the developed STEAM integrated program in prior and post conditions on 3 elementary school's students in J Province, it was discovered that significant improvement was found in the creativity and scientific interest of elementary students in the experimental group, compared to the control group. Therefore, continuous and systematic development of the STEAM integrated education program is required, and moreover, it must be developed for all elementary grade levels and efforts should be put into actively applying the program in the field of education.

Since 2011, after beginning of the systematic study on STEAM education, South Korea has developed a number of related programs. At this point we see that this is the time to clarify the challenges. The purpose of this study is to clarify the characteristics of their education through the review of many domestic and foreign papers in order to propose the challenges of STEAM education of Korea. The results are as follows. First, the course of integration cannot be separated by the difference in superiority but should be separated in accordance with the purpose of integration. Second, curriculum integration such as STEAM education is characterized by the emphasis on horizontal linking than vertical depth fusion. Accordingly, the content knowledge and vertical linkages are inevitably weakened. In order to overcome this problem, the key concepts and features that were emphasized in the previous curriculum need to also be emphasized in STEAM training, and the comparative study on the core concept and function of each subjects should be preceded. Third, after looking upon the current situation of our country's fusion research and talent training, the limits and the challenges that need to be overcome has been suggested. Fourth, with the basis on research results, we offered an example of the approach on STEAM education which is applicable to the current situation and proposed the challenges and implications that need to be addressed in the STEAM education of Korea in educational contexts such as curriculum, teaching and learning, and evaluation.

The first technological advance to improve the output and efficiency of the latest steam turbines operating in co-generation plants in Korea can be said to be progress in the field of materials that can use high-temperature, high-pressures steam. As a result of design efforts to improve the internal efficiency of steam turbines along with the development of materials, only a few manufacturers of steam turbine have produced high efficiency steam turbines. The internal efficiency of a steam turbine on the steam path operating for a long period of time is gradually lost owing to the limit of mechanical life, and efficiency and output decrease. Therefore, this study aims to develop a model that can analyze the steam flow path performance of HP (High Pressure) and IP (Intermediate Pressure) steam turbine for a co-generation plant using a commercial program and propose a performance calculation method. Owing to the complex performance calculation method of steam turbines, major variables are presented to serve as practically useful references for steam turbine practitioners. In addition, the thermal dynamic analysis(such as heat balance diagram calculation) and the the thermal dynamic calculation required for steam turbine performance calculation and the suitability of the steam turbine performance calculation results were compared with the performance test results.
