A new moment of inertia experiment apparatus different from the existing one has been developed, which does not require deformation of a sample in order to fix it to the apparatus. This new experiment apparatus was able to experiment with constant-shaped objects that did not deform the samples, so that it enabled them for conducting an experiment which is close to an ideal rigid model dealt in the general physics course. The new experimental apparatus was easy and accurate in measuring the physical quantity by using the experimental principle of physical pendulum. In the results of the measurement of the moments of inertia of the six samples, all measurements were made to be accurate enough to measure with very small errors within 1%. In addition, it has been found to be useful as an experiment apparatus to understand the concept of the moment of inertia and to prove the formula for moment of inertia. Therefore, if the new moment of inertia experiment apparatus developed in this study is used in students' experiments, it is expected that students will be able to greatly increase their understanding of the concept of moment of inertia.

The purpose of this study was to compare and analyze the employment rate of engineering graduates in the last eight years (2011-2018) by gender and majors. Using the statistical yearbook for employment of higher education graduates provided by the Korea Educational Development Institute (KEDI), the employment rate and retained employment rate of engineering graduates were investigated. As results, first, the employment rate has been decreasing since 2011, and the gender employment rate gap has not narrowed and women have always been lower than men. Second, most of the engineering graduates were workers with employee health insurance. On the other hand, women were higher than men in works with self-employee health insurance. Third, from 2016 to 2018, the retained employment rate of engineering graduates was similar, and as the survey progressed, the retained employment rate decreased. In particular, women had lower retained employment rate than men. The study is meaningful in that it suggested ways to bridge the gap between gender and majors employment rates of engineering graduates.

Recently, the acquisition of teamwork skills as well as creativity has been a special challenge to engineering students. Also it became crucial for engineering educators to help them enhance effectively these skills. Thus, there has been a good deal of domestic and overseas research on teamwork skills and creativity. However, to date, there is relatively few studies analyzing two variables' relationships. This research aims to explore relationships between engineering students' teamwork skills and everyday creativity, and to suggest educational implications for future research and educational programs. For this purpose, this study was conducted with 450 engineering students at two universities in Korea, and their teamwork skills and everyday creativity have been measured. Our findings show that firstly, there were significant differences in teamwork skills by grade. Secondly, there were significant correlations among subcategories' variables of teamwork skills and everyday creativity. Thirdly, 35% of teamwork skills were explained by everyday creativity. Based on these findings, the theoretical and practical implications are discussed with particular attention to education for promoting teamwork skills.

The purpose of this study is to develop and validate an Engineering Empathy Instrument. Engineering empathy is defined as the ability that encompasses the following three qualities, a skill to interpret social issues and phenomenon that may occur in the process of interactions between human beings and engineering systems, a practical orientation that enables one to take stakeholders' perspectives to carry out an engineering project, and a professional way of being that acknowledges empathic skills and associated practice orientations. Based on this notion, we develop a scale to measure engineering empathy and have surveyed 429 engineering students. Evidence for the validity and reliability of the scale is presented. In conclusion, we find that engineering empathy can be measured and conceptualized as three domains: a Learnable Skill (ELS), a Practical Orientation (EPO), and a Professional Way (EPW). We also find that sophomores show the highest level of engineering empathy as compared with other graders. While students accumulate technical knowledge, their understanding about engineering in social and interpretational contexts gets weakened. This implies that engineering education necessarily emphasizes the impacts of engineering solutions in interpersonal, societal, technologies, and environmental contexts.

Here we analyze a case of redesigned course named "Prospect of Nuclear Engineering" as an example of student-entered education which came to the fore of university education innovation. This course was reformed from lecture-based to student-centered class by changing the context as follows: Stimulating students by addressing various problems or episodes behind scientific and mathematical concepts in the history; Offering experimental project to perceive the importance of differential equations; Exploring the research status and issues of nuclear engineering and the ways of attacking them by discipline; Discussing the public acceptance of nuclear power plants. Small group activities using 'small group discussion' and 'peer-learning' have been applied in this course to enhance students' critical and creative ability. In the survey, students rated highly in the fact that they could actively interact with the peers and that they could think for themselves through 'small group discussion' and 'peer-learning' which is not just the way of conveying knowledge.

The government has tried to develop a platform for systematically collecting and managing engineering education data for policy proposals. However, there have been few cases of big data analysis platform for policy proposals in engineering education, and it is difficult to determine the major function of the platform, the purpose of using big data, and the method of data collection. This study aims to collect the cases of big data analysis systems for the development of a big data system for educational policy proposals, and to conduct a study to analyze cases using the analysis frame of key elements to consider in developing a big data analysis platform. In order to analyze the case of big data system for engineering education policy proposals, 24 systems collecting and managing big data were selected. The analysis framework was developed based on literature reviews and the results of the case analysis were presented. The results of this study are expected to provide from macro-level such as what functions the platform should perform in developing a big data system and how to collect data, what analysis techniques should be adopted, and how to visualize the data analysis results.

Folded structure is widely applied in various engineering fields. Many of the Japanese folding fans in the Edo era (1603-1868) have been successfully blended with the processing technology of "natural materials" that is the origin of Japan's "Monodzukuri" (craftsmanship) and its application "artistic originality". The charm of a fan lies in the diversity of stereoscopic expression not born in plane representation. For example, the effects of folds, the expression of the front and back sides flowing from the front to the back by double-sided description, and the two-layer effect of raising the backside from the surface using the permeability of Japanese paper, the calculated depiction are also seen. Moreover, by handling the fan, it also produced an illusion effect which skillfully calculated the change due to movement of the viewpoint. Students experience the natural materials such as Japanese paper, bamboo and starch paste, which are the materials of paint and fan at the time, and processing method, and know the difference with the current one. This study is to verify the effectiveness of engineering education which gains experience by making concrete fans and to understand deeply this traditional technology with the artistry of a Japanese fan at the same time. And we can learn from the characteristics of the fan to Japan's history and culture.

This paper suggests the necessity of design education to engineering majors through qualitative research on the characteristics of intelligent artifacts. Robot cleaner is one of intelligent artificial objects that can approach people's life without awkwardness. How do people think of robot cleaners and define their personality, these days? In this experiment, subjects use and observe four different robot cleaners that have different appearances, behaviors and sounds in an experimental setup where is similar to actual use environment. We measure subjects' preferences and assessments for four different robot cleaners' personality. The test subjects were 11 designers who frequently collaborated with engineers and were able to express and express opinions about products. Experimental results showed that robot cleaners with the highest scores in appearance, behavior, and sound had the highest preference. In contrast, robot cleaners with low scores in three factors showed different results in the preference ranking.

This study examined the relationships among grit, life goal, and conscientiousness of engineering students. In this study, students' goals were categorized into either achievement-oriented goals or life-oriented goals for analysis. A cluster analysis was conducted using students' grit and life goals to analyze their psychological characteristics focusing on conscientiousness A sample of 123 engineering college students participated in this study. Results of correlation analysis showed positive correlations among grit, life goals, and conscientiousness. Results of cluster analysis suggested that student could be categorized into three different groups: Low-grit and high-goals (Group 1), high-grit and high-goals (Group 2), and low-grit and low-goals (Group 3). Among those three groups significant group differences were found in several sub-scales of conscientiousness. Group 1 and 3 showed significant differences in industriousness from Group 2. Group 1 showed significant differences in perfectionism from Group 2 and 3. Based on the findings of this study, theoretical and practical implications were discussed.
