Design optimization is a mathematical process to find an optimal solution through the use of formal optimization algorithms. Design plays a vital role in the engineering field; therefore, using design tools in education and research is becoming more and more important. Recently, numerical design optimization in fluid mechanics, which uses computational fluid dynamics (CFD), has numerous applications in the engineering field, because of the rapid development of high-performance computing resources. However, it is difficult to find design optimization software and contents for educational purposes in aerospace engineering. In the present study, we have developed an aerodynamic design framework specifically for an airfoil, based on the EDucation-research Integration through Simulation On the Net (EDISON) portal. The airfoil design framework is composed of three subparts: a geometry kernel, CFD flow analysis, and an optimization algorithm. Through a seamless interface among the subparts, an iterative design process is conducted. In addition, the CFD flow analysis and the design framework are provided through a web-based portal system, while the computation is taken care of by a supercomputing facility. In addition to the software development, educational contents are developed for lectures associated with design optimization in aerospace and mechanical engineering education programs. The software and content developed in this study is expected to be used as a tool for e-learning material, for education and research in universities.

To respond to the announcement of the revised version of science curriculum early this year, it has been necessary to develop new science textbooks which can be appropriate and effective to achieve the goals of the revised curriculum. The system of new textbooks needs to embrace the concerns of cognitive development in scientific knowledge, skills, and attitudes as well as social and cultural demands in the rapidly changing society. To develop an innovative framework of science textbooks, we examined previous studies on textbook analysis in Korea and analyzed science textbooks in the United States, Singapore, and Japan. We analyzed various ways of introducing and developing conceptual knowledge, leading scientific inquiry skills and process, enhancing scientific attitudes toward science, technology, society and the environment in those science textbooks. In the process of framing the structures of textbooks, we focused on ways of increasing educational effects of visualized texts, leaners' interest, user-friendly procedure, scientific inquiry, effectiveness of hands-on activities, scientific reading and writing skills, and usage of workbook. Based on those aspects and analyses of textbooks, we attempted to propose a feasible framework of Grade $3{\sim}4$ Science textbook which can effectively respond to the educational changes and demands in the local and global society.

The purpose of this study was to explore the use of the city biodiversity index (CBI) as a tool to improve biodiversity education for urban students. For use in educational purpose, the CBI was modified and supplemented to devise an Educational CBI, and its ability to facilitate the teaching of biodiversity topics was assessed. An Educational CBI that can be used at the high school level was successfully developed. Evaluation criteria were selected based on previous studies of the existing CBI and domestic circumstances, and the relationship between the index and biodiversity topics was revealed in detail. An examination of the relevance of the Educational CBI with the current biodiversity curriculum framework showed it to be highly relevant at the level of investigation and evaluation as a tool for measuring urban biodiversity. Furthermore, an examination of the relevance between the CBI for Education and the achievement standards of the general high school subjects of the 2022 revised curriculum indicated high relevance in environmental and science subjects. As an example, the city of Cheongju obtained 82-85 of 112 points in an evaluation using the Educational CBI, confirming the monitoring function of the index. Overall, the Educational CBI offers significant benefits as a tool for both biodiversity education and urban environmental education.

When the design profession started, design targets were mainly static hardware centered products. Due to the development of network and digital technologies, new products with dynamic and software-hardware hybrid interactive characteristics have become one of the main design targets. To accomplish the new projects, designers are required to learn new methods, tools and theories in addition to the traditional design expertise of visual language. One of the most important tools for the change is effective and rapid prototyping. There have been few researches on educational framework for interactive product or system prototyping to date. This paper presents a new model of educational contents and methods for interactive digital product prototyping, and it's application in a design curricula. The new course contents, integrated with related topics such as physical computing and tangible user interface, include microprocessor programming, digital analogue input and output, multimedia authoring and programming language, sensors, communication with other external devices, computer vision, and movement control using motors. The final project of the course was accomplished by integrating all the exercises. Our educational experience showed that design students with little engineering background could learn various interactive digital technologies and its' implementation method in one semester course. At the end of the course, most of the students were able to construct prototypes that illustrate interactive digital product concepts. It was found that training for logical and analytical thinking is necessary in design education. The paper highlights the emerging contents in design education to cope with the new design paradigm. It also suggests an alterative to reflect the new requirements focused on interactive product or system design projects. The tools and methods suggested can also be beneficial to students, educators, and designers working in digital industries.

Evaluating the effectiveness of educational programs involves measuring learning processes as well as outcomes. It is essential to study cohorts of students and graduates to evaluate the long-term effects of educational programs with data generated both during education and after graduation. The purpose of this study was to establish cohorts of students and graduates to evaluate their performance, thereby providing a basis for evaluating the social accountability of medical education. In this study, student and graduate cohorts were built for both students currently enrolled and graduates at Inje University College of Medicine (IUCM). A model involving the process of cohort establishment and an evaluation indicator framework was developed. In the process of cohort establishment, the following steps were conducted: defining the goals and objectives of the student and graduate cohorts, organizing a cohort committee, developing regulations, registering cohorts, acquiring consent, and building a database. A framework of evaluation indicators according to the graduate roles of IUCM was developed by adapting Kirkpatrick's evaluation model. Next, items to be collected in student and graduate cohorts were selected, and the current status of existing data was analyzed. Moreover, a preliminary analysis was conducted, including analyses of the evaluation indicators and graduates' performance. This study suggests that it is necessary to include additional evaluation indicators considering students' learning environment and well-being in student cohorts and to develop strategies or methods for graduates to continue participating in data collection for a long-term study.

Although many researchers and science educators agree that understanding of the nature of science is essential in order for students to be a scientific literate person, it is not easy to compromise exactly what kind of understanding of the nature of science is required to achieve this goal (Smith & Scharmann, 1999). This study discusses a theoretical background about the nature of science (NOS) including some consensus views of the NOS that several important U.S. educational reform documents and science researchers have presented over the past several decades. Finally, this study proposes an inclusive framework of the nature of science based on the four categories of scientific literacy, which are (1) science as a body of knowledge, (2) science as a way of investigating, (3) science as a way of thinking, and (4) the interaction of science, technology, and society. Each category of the framework includes several statements about the nature of science to describe each theme of the NOS. This framework is comprehensive and inclusive because it is suggested by examining several major U.S. national-level documents and in the publications of science education researchers presented about the nature of science. Significantly, many of the key ideas were added into category (4) and category (3), which indicates that the current literature stresses the relationship among science, technology, and society as well as the work of scientists.
