Social engineering attack means to get information of Social engineering attack means to get information of opponent without technical attack or to induce opponent to provide information directly. In particular, social engineering does not approach opponents through technical attacks, so it is difficult to prevent all attacks with high-tech security equipment. Each company plans employee education and social training as a countermeasure to prevent social engineering. However, it is difficult for a security officer to obtain a practical education(training) effect, and it is also difficult to measure it visually. Therefore, to measure the social engineering threat, we use the results of social engineering training result to calculate the risk by system asset and propose a attack graph based probability. The security officer uses the results of social engineering training to analyze the security threats by asset and suggests a framework for quick security response. Through the framework presented in this paper, we measure the qualitative social engineering threats, collect system asset information, and calculate the asset risk to generate probability based attack graphs. As a result, the security officer can graphically monitor the degree of vulnerability of the asset's authority system, asset information and preferences along with social engineering training results. It aims to make it practical for companies to utilize as a key indicator for establishing a systematic security strategy in the enterprise.

Recently, 3D printing has received increasing attention due to its boundless potentials. Because 3D printing starts from 3D geometry information, computer-aided design (CAD) is an essential technology to build 3D geometry data. These days, education of 3D CAD for engineering students has been changed from the theoretical lecture to practical design training using commercial CAD software. As a result, open-ended design projects have replaced the traditional theoretical examinations to evaluate students' outcomes. However, such design projects are not enough to evaluate students' outcomes because their results are expressed in two-dimensional ways. In this paper, applications of 3D printing in engineering design education are discussed by describing the procedure and outcomes of design projects. It was found that the use of 3D printing could improve students' outcomes by fabricating real physical models out of their designs.

This study attempted to examine the effect of education and training on organizational performance based on HCCP research through the systematic review of previous studies. For this, 29 papers used HCCP data were selected and analyzed, and the research results are as follows. First, the research results showed that education and training had a positive effect on non-financial performance such as organizational commitment and job satisfaction, and financial performance such as sales and operating profit. Second, in order for education and training to affect organizational performance, job satisfaction, organizational culture, and education transfer were found to be important factors. Third, for effective transfer of education and training, it is necessary to establish a system that can be applied to the field after education and training, finally, it suggested the need for research to be conducted to reveal the practical effectiveness of education and training by measuring the degree to which education and training contributed to financial performance more closely.

Circuit theory is a systematic study that analyzes and designs the most basic circuits in the field of electrical and electronic engineering. Circuit theory courses are organized as major courses for one or two semesters in the second year of university, so that electrical and electronic engineering students must learn. Experimental courses are being together organized for students to enhance understanding of circuit theory and cultivate the skills and the abilities of circuit design through experiments with actual circuits. This paper is a case study on the teaching method applied in electric circuit design and experiment courses to enhance the learning effect on the experimental education that supports circuit theory. To do this, we propose a 15-week instructional model consisting of theory study, simulation, experiments, and design projects. In the proposed model, the simulation and preliminary experiment preparation process are reinforced to complement the theoretical concept and the design project is introduced to acquire practical circuit design skills as engineers. The results of five-year operation demonstrate the effectiveness of the proposed model.

In a future society where cutting-edge science technology such as artificial intelligence becomes commonplace, the demand for talented people with basic knowledge of mathematics and science is expected to increase continuously, and the educational infrastructure suitable for the characteristics of future generations is still insufficient. In particular, in the case of students taking convergence courses including practical training, there was a problem in communication with the instructor. In this study, we looked at the current status of distance learning at domestic universities that came suddenly due to the global pandemic of COVID-19. In addition, a case study of the use of technology was conducted to facilitate the interaction between instructors and learners through case analysis of distance classes in convergence subjects. Therefore, this study aims to introduce the case of developing lecture contents for smooth convergence education in a non-face-to-face educational environment targeting the developed AI convergence courses and applying them to the education of enrolled students.

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.

This study suggests the direction of management theory education in business administration under the university-linked program of Korean work and study in parallel policy. As a social science, business education is essentially to cultivate people of talent capable of making the right decisions in the social phenomenon (business practices) rather than educate skills for solving a specific issue. At the same time, the parallel system is aimed at cultivating talented people who can work practically in the real field. Therefore, practical education and theoretical education should be linked organically, and the theoretical education should be layered. Also, management education should be guaranteed to be timely and cultivate fusion thinking. Based on this background, this study is expected to contribute to the upgrading of the parallel system and education level in the future by reviewing the curriculum of the business administration department of domestic universities.

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.
