Engineering education accreditation, such as by ABEEK in Korea or ABET in USA, centers around outcomes-based education (OBE). Outcomes are the abilities or competencies which students are expected to achieve by the time of graduation. Engineering programs must design the curriculum, educate their students, and assess the performance of them in accordance with the program outcomes. Consequently, sound understanding of the program outcomes is crucial to the successful implementation of OBE. Most of the 12 outcomes of ABEEK KEC2005 criteria came from ABET criteria written in English. It means that, apart from sound understanding of the outcomes, we need to care about the correct translation of the ABET outcomes from English to Korean. The translation of them as in KEC2005, however, leaves something to be desired. This paper tries to present the correct translation of some program outcomes as well as sound understanding of a few outcomes difficult to define.

The present work was mainly concerned with studying the operation of RC-phase shift oscillator based on MOSFET type 2N6660 under the influence of different temperature levels ranging from room temperature (25 ℃) up-to135 ℃ and gamma-irradiation up-to 3.5 kGy. In this concern, both the static (I-V) characteristic curves of MOSFET devices and the output signal of the proposed oscillator were recorded under ascending levels of both temperature and gamma-irradiation. From which, it is clearly shown that the drain current was decreased from 0.22 A, measured at 25 ℃, down to 0.163 A, at 135 ℃. On the other hand, its value was increased up-to 0.49 A, whenever the device was exposed to gamma-rays dose of 3.5 kGy. Considering RC-phase shift oscillator, the oscillation frequency and output pk-pk voltage were decreased whenever MOSFET device exposed to gamma radiation by ratio 54.9 and 91%, respectively. While, whenever MOSFET device exposed to temperature the previously mentioned parameters were shown to be decreased by ratio 2.07 and 46.2%.

The present paper reports on a trial to shed further light on the characterization, applications, and operation of radar speed guns or Gunn diodes on different radiation environments of neutron or g fields. To this end, theoretical and experimental investigations of microwave oscillating system for outer-space applications were carried out. Radiation effects on the transient parameters and electrical properties of the proposed devices have been studied in detail with the application of computer programming. Also, the oscillation parameters, power characteristics, and bias current were plotted under the influence of different ${\gamma}$ and neutron irradiation levels. Finally, shelf or oven annealing processes were shown to be satisfactory techniques to recover the initial characteristics of the irradiated devices.

The purpose of this study is to analyze the effectiveness of arts-engineering interdisciplinary education for improving creativity-convergence thinking. Using response data from 263 participants who attended an arts-energy extracurricular program at K University, we applied Kirkpatrick's Four-Level Model for analysis, and used Excel 2018, SPSS 25.0, and Process macro 4.0 software programs. The main findings are as following: (a) Overall means for STEP1: program satisfaction (M=4.43), STEP2: understanding of the program (M=4.52), STEP3: increased interest in energy (M=4.26), and STEP4: expansion of creativity-convergence thinking (M=4.41) were high, indicating effective learning outcomes. (b) While STEP1 did not differ significantly, males showed significantly higher in STEP2 and STEP3 compared to females. Additionally, males and STEM learners was significantly higher in STEP4 than non-STEM learners. (c) STEP1 had a positive effect on STEP2, and STEP3 had a positive effect on STEP4, but STEP2 did not have an effect on STEP3, failing to support the assumption of serial causality in Kirkpatrick's model. STEP1, STEP2, and STEP3 had positive effects on STEP4 directly. STEP2 or STEP3 mediated the relationships between STEP1 and STEP4 respectively. However, STEP2 and STEP3 did not serially mediate the relationships between STEP1 and STEP4. Based on these findings, discussions were held, and implications for academia and practice in the fields of engineering and science education were provided.

Artificial intelligence (AI), an essential skill of the Fourth Industrial Revolution, is being actively taught in higher education; however, AI education is only in the preparatory stage in elementary, middle, and high schools. Investigating various newspaper articles related to AI education to date can aid in basic data collection, which is an important process in the preparatory stage. Accordingly, 13,378 newspaper articles were collected from a total of 21 newspapers, and five topics were extracted using the latent Dirichlet allocation (LDA)-based topic model along with frequency analysis. Newspaper articles from the early 2000s expanded to technologies related to the Fourth Industrial Revolution. Accordingly, education in AI fields should be linked with education in AI-based technology. In addition, efforts should be made to secure the continuity and sequence of AI education in cooperation with related higher institutions and companies.

This paper is to propose a curriculum of a subject of Enneagram which is to be open to develop key competency of university students. In the modern days of the 4th industrial revolution universities are being called for key competency-based education and innovation in education. Universities suggested various key competencies according to the university's founding philosophies. And they have been reorganizing the liberal arts curriculum in a way that it can reinforce key competencies of the students in the aspect of liberal arts education. In this paper, an example of C university which has 3 key competencies such as, citizenship, character, and creative intelligence was presented. Enneagram is a good candidate for developing self-development which is sub-competency of character.

In the rapidly changing society since the Fourth Industrial Revolution, the cultivation of convergence talents that can solve complex problems is emerging as an important issue. The purpose of this study is to propose the core competencies required to establish the program learning outcomes of the engineering and education curriculum, which is the accreditation standard of engineering education proposed by ABEEK(Accreditation Board for Engineering Education of Korea). Case study methodology was applied to achieve the purpose of the study. The case of analysis is design and software convergence majors of domestic and foreign universities. The educational objectives and course syllabi were analyzed. As a result of the research, four core competencies to be achieved in the design and software convergence majors were derived in addition to the ten program outcomes presented by ABEEK. New core competencies are convergence ability, creative thinking, entrepreneurship, and design ability. The result of this study is expected to contribute to the development of the evaluation system for the convergence engineering education field.

This research aims to explore the factors affecting engineering students' major persistence and career decision. To achieve this goal, the experiences and perceptions of engineering students and other stakeholders regarding the factors influencing engineering students' major persistence and career decision were analyzed through online focus group interviews (FGI). The analysis of the interviews resulted in the identification of seven categories, which include meeting with older alumni, team project experiences, and internship experiences as factors influencing major persistence. Additionally, engineering interest, engineering self-efficacy, employment rates, economic factors, and limitations in women engineers' career development were identified as factors affecting career decision. Based on these findings, it is expected that engineering education will develop plans that focus on supporting the major persistence and career development of engineering students, thereby contributing to the future direction of engineering education.
