This study analyzes the public lecture conducted by a university in Seoul and examined how a public lecture on the emergence of a new media environment could influence the actual field of engineering education. The current public lecture is changing away from past patterns which have been conducted on a daily, irregular and offline basis. Online lectures such as Mooc programs, as well as broadcast programs in the Internet media environment, are becoming increasingly popular with mainstream education. This study focuses on exploring how public lecture experiences of engineering professors have affected the improvement of learner centered education and their communication skills. It also examines how public lecture in the field can affect to enhance public understanding of engineering. The advent of a new media environment is likely to inject new vitality into a college lecture that seems to fall behind in the past. It is highly likely that the reliance on the teaching capabilities of professors become higher according to the emphasis on active learning environment. The genre of public lecture is expected to greatly helpful to expand future engineering education methodologies.

Outcomes based engineering education is not necessary only for the accreditation by the ABEEK, but the actual improvement and enhancement of the engineering education. Also, it is the new and big trend in engineering education filed world widely. The new methodology for performing outcomes based education has been proposed for engineering education and the practical application for so called 'life-long learning' outcome has been presented. Furthermore, the way to 'close-the-loop' for CQI(continuous quality improvement) in engineering education has been shown.

Safety is paramount for construction industry throughout the world. Human errors which contribute to more than half of construction accidents, could be proactively prevented through effective education and training methods. Although Virtual Reality (VR) and Augmented Reality (AR) have gained much attention in various disciplines, few studies applied them for construction safety education. This research presents a new approach in construction safety education by utilizing VR and AR. The vision of aligning teaching & learning strategies is examined in order to ensure the potential benefits of the new method. This innovative approach shifts safety education from "Listen, and I will forget. See, and I may remember" towards "Practice, and I understand".

Transuranic nuclides (such as ²³⁸Pu, ²⁵²Cf, ²⁴⁹Bk, etc.) have a wide range of application in industry, medicine, agriculture, and other fields. However, due to the complex conversion chain and remarkable fission losses in the process of transuranic nuclides production, the generation amounts are extremely low. High flux reactor with high neutron flux and flexible irradiation channels, is regarded as the promising candidate for producing transuranic nuclides. It is of great significance to increase the conversion ratio of transuranic nuclides, resulting in higher efficiency and better economy. In this paper, we perform an optimization design evaluation of producing transuranic nuclides in high flux reactor, which includes optimization design of irradiation target and influence study of reactor core loading. It is demonstrated that the production rate increases with appropriately determined target material and target structure. The target loading scheme in the irradiation channel also has a significant influence on the production of transuranic nuclides.

The k-eigenvalue neutronics/thermal-hydraulics coupling calculation is a key issue for reactor design and analysis. Jacobian-free Newton-Krylov (JFNK) method, featured with super-linear convergence rate and high efficiency, has been attracting more and more attention to solve the multi-physics coupling problem. However, it may converge to the high-order eigenmode because of the multiple solutions nature of the k-eigenvalue form of multi-physics coupling issue. Based on our previous work, a modified JFNK with a line search method is proposed in this work, which can find the fundamental eigenmode together with thermal-hydraulics feedback in a wide range of initial values. In detail, the existing modified JFNK method is combined with the line search strategy, so that the intermediate iterative solution can avoid a sudden divergence and be adjusted into a convergence basin smoothly. Two simplified 2-D homogeneous reactor models, a PWR model, and an HTR model, are utilized to evaluate the performance of the newly proposed JFNK method. The results show that the performance of this proposed JFNK is more robust than the existing JFNK-based methods.

Air ingress incidents are major safety accidents in very-high-temperature reactors (VHTRs). Air containing a high volume fraction of oxygen may cause severe oxidation of core components at the VHTR, especially for the significantly thin alloy tube wall in the intermediate heat exchanger (IHE). The research objects of this study are Inconel 617 and Incoloy 800H, two candidate alloys for IHE in VHTR. The air ingress accident scenario is simulated with high-temperature air flow at 950 ℃. A continuous oxide scale was formed on the surfaces of both the alloys after the experiment. Because the oxide scale of Inconel 617 has a loose structure, whereas that of Incoloy 800H is denser, Inconel 617 exhibited significantly more severe internal oxidation than Incoloy 800H. Further, Inconel 617 showed a significant decrease in ultimate tensile strength and plasticity after aging for 200 h, whereas Incoloy 800H maintained its tensile properties satisfactorily. Through control experiment under vacuum, we preliminarily concluded that serious internal oxidation is the primary reason for the decline in the tensile properties of Inconel 617.

This study proposes a new educational approach to basic engineering education using reverse-engineering. A freshmen level engineering coursework provided by the University, 'Engineering Design', is to deliver the understanding of the general relationship between their major and its adjacent engineering fields. Students are to understand the identity of their major fields through this effort. There are some limitations, however, to achieving these educational objectives by providing lectures in a classroom environment or practical experience because of the broad nature of the subject. A new educational approach on 'Engineering Design' has been implemented for past five years to achieve this goal using reverse-engineering techniques and this paper describes it in detail.

We analyzed the relationship based on the complex system between engineering writing in accreditation program and engineering education accreditation system and studied an effective engineering writing education system for engineering education in this paper. By introducing accreditation system, the engineering education system keeps continuously an emergent behavior and builds the new system. In this point of view, this research proposed an situated learning system and introduction of writing portfolio. As a result, we ascertain this proposed way makes up writing skill of students. We think this discussion will be a chance to explore a new writing education system in engineering education.

Possible directions of chemical engineering education have been proposed in many studies. However, new curriculum is demanded to accommodate the special needs of our students' level and community industrial characteristics. We can think of two reasons. One is that various kinds of chemical engineering industry are found in every community. The other is that students' educational standards are different in every university. We have surveyed and analyzed jobs of our university graduates who are working in chemical company of our community Pusan and Kyoung-Nam. This study aims to develop the new curriculum with an emphasis on practical education and to propose the new direction for our major characteristic based on the survey.
