산업기술 변화에 능동적으로 대처할 수 있는 현장중심의 공학교육을 위해서는 현장경험이 풍부한 강사, 교재, 교육콘텐츠와 더불어 현장과 연계된 교육장비의 활용이 반드시 필요하다. 기존의 교육장비는 현장중심이 아닌 해당 기술을 쉽고 편리하게 교육하기 위한 보편적인 장비가 주류를 이루고 있다. 이는 산업기술 변화에 따라 관련 공학교육이 뒷받침되고 있지 못하고 현장교육과 점점 멀어져가는 이유이다. 이에 본 논문에서는 공학교육에 있어서 중요한 역할을 하고 있는 교육훈련 장비의 개발사례를 살펴보고 이들 장비를 실제 교육에 활용하였을 때의 만족도 조사를 분석하여 향후 현장중심의 공학교육에 적합한 교육장비 개발 및 활용 방안을 제시하고자 한다.

The purpose of this study was to analyze needs of convergence education on engineering and human resource development (HRD) for students in H university for increasing creative problem solving skills. To achieve the research purpose, needs analysis was conducted to students through in-depth interview about students' project experience for graduation in H university. The research finding shows that the converged areas between engineering and HRD are: connecting technologies to social context, problem solving skills, leadership, communication skills, and teamwork skills. Based on the derived five converged areas, objectives and method of the engineering-HRD convergence education are discussed. As an effective teaching and learning method, a problem-based learning and a project method are suggested. Finally, considerations for successful implementation of the engineering-HRD convergence education are discussed.

This study aims to conduct a case study of the Science, Technology, Engineering, Arts, and Mathematics (STEAM) outreach program development and their application. This program was operated by 184 middle and high school students at C University on October 2014. The major results of these studies were as follows: First, The theme of the outreach program consisted of four engineering areas, aerospace engineering, chemical engineering, architectural engineering, and mechatronics (robot) engineering; moreover, the materials for the students' workbook, the guidebook for teachers, and the program operation manual for staffs in a university were developed by working with four authors and ten subject matter experts. Second, the satisfaction level with the contents and activities was ranged from 4.24-4.31 out of 5 points. Third, the vitalizing activation plan was discussed for the sustainable development and operation of the STEAM outreach program.

The purpose of this study is to develop an educational program to enhance convergence competence of undergraduate engineering students and analyze its educational effects. Prior to the development of the convergence education program for engineering students, 13 experts in engineering education field surveyed the needs of the convergence education program and 829 students from four engineering colleges in the Seoul metropolitan area, Chungcheong area and Honam area were assessed for the level of convergence competency. The educational program was developed based on the needs analysis and the program consisted of four major themes: convergence lecture, convergence competence, convergence practice, and convergence vision. The validity of the program was confirmed through the two expert validation tests. A total of 40 students participated in the selection of 10 students from each of the four universities. As a result of pre-post comparison of students' convergence competencies, the average of all competencies increased, and it was found that there were statistically significant differences in convergence mindset, differentiation mind, commitment, communication, and social value competence. Implications for the improvement of education programs and convergence education were suggested.

This paper deals with a result of case study for the development of CEA(Course-Embedded Assessment) design tool for engineering education accreditation implementing programs. Many programs have been devoting efforts to apply CEA to their engineering education. In order to effectively apply the CEA to educational program, it is required to develop the standardized form or scheme for CEA application. As a preliminary approach, we propose the design tool and the result of a case study for CEA application in engineering education.

est19 is a gene from Bacillus sp. K91 that encodes a new esterase. A comparison of the amino acid sequence showed that Est19 has typical Ser-Gly-Asn-His (SGNH) family motifs and could be grouped into the SGNH hydrolase family. The Est19 protein was functionally cloned, and expressed and purified from Escherichia coli BL21(DE3). The enzyme activity was optimal at 60℃ and pH 9.0, and displayed esterase activity towards esters with short-chain acyl esters (C₂-C₆). A structural model of Est19 was constructed using phospholipase A1 from Streptomyces albidoflavus NA297 as a template. The structure showed an α/β-hydrolase fold and indicated the presence of the typical catalytic triad Ser49-Asp227-His230, which were further investigated by site-directed mutagenesis. To the best of our knowledge, Est19 is a new member of the SGNH hydrolase family identified from thermophiles, which may be applicable in the industrial production of semisynthetic β-lactam antibiotics after modification.

The Asian Conference on Engineering Education has organized and is held in Busan. This paper tells the steps for the process of planning of this conference. Firstly, the Innovation Center for Engineering Education in Korea Maritime University and the Center for Innovation and Creativity Development in The University of Tokushima signed the mutual interchange agreement on engineering education in 2005. The interrelation of both centers has made a continuous relation by mutual visiting of teachers and students. The first symposium on engineering education between the two universities was held in 2006. Three symposia were succeeded until now. By the way, the Japanese five-university coalition of engineering education was composed in 2004. This five-university coalition annually held the symposium on engineering education. Two teachers and two students of each university participated in the symposium and introduced their activities. Annual symposium was held every year from 2004 to 2008. Based on these two kinds of symposium, we have planned to enlarge the relationship by including partner universities in both countries. The capstone design coalition on engineering education between the Center for Innovation and Creativity Development in the University of Tokushima and the innovation center for engineering education in Korea Maritime University are introduced. The interrelation of both centers has held by mutual visiting of teachers and students during four years. The capstone design activities of Korea Maritime University and the students' creative design projects of the University of Tokushima were introduced each other. This coalition is planned that it needs to be enlarged by including partner universities in Asian countries.

This paper introduces the association method for the program outcomes of engineering education accreditation and the competency units of National Competency Standards(NCS). This association method can be used to efficiently develop an engineering curriculum that is based on both of the NCS and the engineering education accreditation. The association method consists of an analysis phase, an association phase and a checking phase. We also deals with the curriculum development procedure that uses the proposed association of program outcomes and competency units. Also, we provide the application of this method to the computer engineering program for NCS-based engineering education accreditation. Thus we can systematically and efficiently develop curriculums for the NCS-based engineering education accreditation by using the proposed method.

This paper presents an experimental investigation about visualization of bulging development of geosynthetic-encased stone column (GESC) based on the digital image correlation (DIC) technique and transparent soil. Visual model tests on GESC and ordinary stone column (OSC) were carried out. In order to delete the warping effect resulting from transparent soil and experiment setup, a modification for experiment results was performed. The bulging development process of the GESC and the displacement field of the surrounding soil were measured. By comparing with the existing experimental and theoretical results, it demonstrates that the model test system developed for studying the continuous bulging development of GESC is suitable. The current test results show that the bulging depth of GESC ranges from 1.05 to 1.40 times the diameter of GESC. The influence depth of GESC bulging on surrounding soil displacement is 0~3 the times diameter of GESC.
