An 'Introduction to Creative Engineering Design' course at College of Engineering at Chungnam National University is required for all freshmen. The objective of this course is to educate the freshmen with basic engineering design concepts and experiences in creative problem-solving approaches. It provides the students learning opportunities in solving engineering design problems through team efforts and creative approaches. Thus, this course emphasizes creative ideas and thinking, engineering design experiences to students over the course. This study presents the syllabus, the examples of PBL (problem based learning)-related activities as a team, and the results of the course evaluation and outcomes. Based on the results of this study, we can conclude that overall this course using PBL method had significant positive effects on the course outcomes and the creativity of the engineering freshmen in the department of environmental engineering at Chungnam National University. However, there are still efforts to be needed to improve the PBL-related activities in the course, including students' workload, financial supports, and team work.

This study explores the perception of Engineering Design of teachers who have long experience in the Integrated STEAM education. The teachers participating in this study were 12 elementary and secondary teachers with more than five years of experience in the Integrated STEAM Education. The study conducted semi-structured interviews. Interview questions focused on experiences of Integrated STEAM Education and recognition of Engineering Design, whether or not to reflect the curriculum of Engineering Design, and actual cases of Integrated STEAM Education with Engineering Design. As a result of this study, the teachers who participated in this study recognized that 'identification and coexistence of concepts for science, technology, and engineering' about Engineering Design, 'Creative design is possible when creativity is added to Engineering Design', 'Engineering Design is to analyze the economic feasibility and utility of the output created through the creative design process', 'Engineering Design is only for students who choose a career in science and engineering'. Based on this research, We need to establish and present correct concepts for science, technology, and engineering, and make an effort to include Engineering Design for solving scientific problems in the curriculum. In addition, we will have to develop and spread the Integrated STEAM Education program including Engineering Design and apply it in the field. Through this, we will have to find concrete action plans to improve the perception of science and engineering Integrated STEAM programs and Engineering Design among novice teachers and preservice teachers.

In this paper the author proposes a case study of a freshmen introduction to engineering design course ing LEGO Mindstorm NXT and analyzes the survey results of the course. The diffilculties are that this course should provide various aspects of design experiences to the students while not requiring the major knowledge and skills and it should attract the students to the engineering major. According to our case study LEGO mindstorm can be a good solution to this problem. The design experience with LEGO Mindstorm NXT provides students with various aspects of design experiences including defining problem, finding constraints and functions, exploring design space, and performing preliminary design, as well as fun. This paper also provides a project list that can be used for freshmen design experience including soccer game robots, line tracer, and vacuum cleaner etc.

Throughout its short history, the discourses of philosophy of technology has been centered around two issues, namely the recovery of human autonomy in technological society and the pursuit of sustainable development. Following the basic subject matters of the discipline, this article suggests to examine the possibility of the 'ethical engineering design,' meaning that ethical consideration should be included in engineering design. This proposal is based on the critique that philosophy of technology has so far focused on the external approach to the problem of technology, neglecting the active role of engineers. By paying attention to engineering design, however, philosophy of technology can offer a more realistic solution for the problems of the technological society. The first section shows the context of the current discussion by surveying the brief history of philosophy of technology. The thesis of engineering design in philosophy of technology will be presented in the second section, together with supporting reasons. The third section will examine theories and efforts that raised the issue of engineering design in the past. They have been suggested in different contexts, but when put together, they can be used for the justification of the current proposal. The fourth section will deal with the possible critiques of this proposal, which will be followed by suggestions for engineers themselves.

본 논문은 SiC MOSFET의 단락 검출을 위한 고정밀 Rogowski 코일 회로 설계 방법을 제안한다. 설계 방법을 제안하기 위해 먼저 Rogowski 코일의 기본 구성인 적분기를 실제 시스템 요구 사양에 맞추어 설계한다. 설계한 회로의 성능 확인을 위하여 DPT (double pulse test)를 실시하며, test 결과 분석을 통해 문제점을 파악하고 전류 센싱 정밀도 향상을 위해 입출력 필터 설계 및 Rogowski 코일 턴 수를 변경한다. 변경한 각 조건들에 대하여 DPT를 진행하고 각 test 결과를 기반으로 Rogowski 코일 회로 설계 방안을 제안한다.

공학해석기반의 설계/제조 시스템에서의 설계는 설계평가와 설계 trade-offs로 구성되어 진다. 설계평가는 설계의 유용성을 평가하거나 CAD모델을 공학해석 모델로 변환하여 구조해석을 통하여 평가하기 위해 사용되며 이러한 평가결과를 근거로 성능치를 정의하고 CAD모델에서의 치수가 trade-offs 해석을 위한 설계변수로 정의되어 진다. 설길 trade-offs는 개선된 설계를 얻기 위한 목적으로 수행되는 데 설계변경은 CAD와 공학해석 모델로 피드백하게 된다.(중략)

It is a fact that current engineering education is insufficient to cultivate engineers who can fulfill industrial demands. Engineering colleges and the government have expended much effort to develop new education model to overcome these shortcomings. The purpose of the present research is to formulate direction of engineering design education to cultivate talented engineers meeting engineering and industrial needs. We compared and analyzed Creative Design Project (3) (a core subject in engineering design) from the feedback of practising engineers, professors and students based on essential design technology factors and the educational achievement contents of ABEEK. The three essential factors of design technology which are prerequisites for the designers to implement design work were selected by surveying experts in the field of device design of cellular phone company. Moreover, educational purpose of the professors, educational achievement of the students, and educational direction of industry needs are deduced based on the three factors. It is also ascertained that Creative Design Project (3) meets most of the requirements of industrial design field by comparing and analyzing deduced results.

This paper aims to present the model of engineering design education workshop for appropriate technologies. Since 2008 Handong Innovation Center for Engineering Education and a Non-Profit Organization, Sharing and Technology, held engineering design workshop during every summer break. We present the contents of the workshop and analyze the educational effects of the program. The workshop is entitled "Engineering Design Academy for the other 90%" because we take it serious that most of the research and development efforts of the science and technologies in the world is just focused on the rich people while the other 90% people in the world are unreachable from the benefits of the modern technologies. By the workshop we tries to provide the college students the perspectives on the worldwide poverty problems and to encourage them to serve the 3rd world people in need through their specialties in the field of engineering profession. The evaluation results by participants are very positive. Especially, we began invite the 3rd world people to the workshop as design problem clients from 2010 summer workshop. The evaluation from them are also very positive. The analysis results on the educational effects of the workshop show that the workshop improves the students skills required by the ABEEK (Acreditation Board of Engineering Education of Korea) including not only design capability but also team work, communication skill, understanding the social impacts of engineering design, engineering ethics, and globalization.
