Due to the development of science and technology, diversity of fusion technologies has become a major concern. Especially the application of the convergence education became necessary in the curriculum of engineering department. The purpose of this paper is to extract characteristics of convergence education among engineering majors and to present a model of applicable convergence education. The researchers collected studies of past 15 years in domestic and international journals in related themes. Academic research information systems, DBpia, e-article, Academic Search Complete were used for keyword searches. 43 Korean papers and 25 international papers were analyzed for the study. The results showed that the convergence education models for college of engineering can be classified into the three types: the cooperative convergence, multidisciplinary convergence, and transdisciplinary convergence. Based on the results, a convergence education model is suggested for the schools of engineering in Korea.

A series of functionalized furans were synthesized by way of a palladium-catalyzed coupling reaction of 2,3,5-trisubstituted furans with aryl chlorides through C-H bond cleavages at C-4 position. The feature of the reaction was facilitative preparation of furan derivatives with good functional group tolerance. All reactions gave the desired products in moderate to good yields in the presences of $BuAd_2P$ and t-BuOK in DMF at $120^{\circ}C$ after 15 h.

Accreditation of engineering education as initiated by Accreditation Board for Engineering Education of Korea (ABEEK) centers around three key issues: program outcomes, assessment/evaluation thereof, and continuous quality improvement (CQI). Most engineering departments, however, are neither adequately familiar with nor well prepared for the issues, especially CQI. The CQI in almost all departments seems to be overly confined in individual courses and the final capstone design courses for seniors; there is no evidence that CQI is not limited to the course level but flows through all courses in the curriculum. This paper presents a sound and viable framework for CQI implementation in which course-level CQI is integrated into the department/program-level CQI.

The magnetostrictive material is magnetized in magnetic field and produces a nonuniform demagnetizing field inside and outside it. The demagnetization is decided by the permeability of magnetostrictive material and its size. The magnetoelectric performances are determined by the synthesis of the applied and demagnetizing fields. An analytical model is proposed to predict the magnetoelectric voltage coefficient (MEVC) of magnetostrictive/piezoelectric laminate composite using equivalent circuit method, in which the nonuniform demagnetizing field is taken into account. The theoretical and experimental results indicate that the MEVC is positively connected with the permeability and the piezomagnetic coefficient of magnetostrictive material. To obtain the maximum MEVC, both the permeability and the piezomagnetic coefficient of magnetostrictive material should be taken into account in selecting the suitable magnetostrictive material.

Magnetoelectric (ME) transducers were originally intended for magnetic field sensors but have recently been used in vibration energy harvesting. In this paper, a new broadband vibration energy harvester has been designed and fabricated to be efficiently applicable over a range of source frequencies, which consists of two cantilever beams, two magnetoelectric (ME) transducers and a magnetic circuit. The effects of the structure parameters, such as the non-linear magnetic forces of the ME transducers and the magnetic field distribution of the magnetic circuit, are analyzed for achieving the optimal vibration energy harvesting performances. A prototype is fabricated and tested, and the experimental results on the performances show that the harvester has bandwidths of 5.6 Hz, and a maximum power of 0.25 mW under an acceleration of 0.2 g (with g = $9.8\;ms^2$).

In Korea, engineering education based on industry demand is highly emphasized; the survey of industry demand or company satisfaction is frequently conducted. Although engineering schools have often attempted and implemented the reform of engineering education, it was found that company satisfaction with college education was always low. In this context, this study aimed to find the cause of the low satisfaction. To this end, the social background for the active survey of industry demand and company satisfaction, and its progress were investigated. The findings of this study showed that the survey of industry demand in Korea has limitations in improving the quality of college education or developing its future demand, contrary to its intention. This industry demand based approach has its historical and social root in the Korea-specific model of the catching-up style industry development and technology innovation. Therefore, it is difficult to establish appropriate academy-industry relations and discover future vision based on this model. This study presents a new way to understand and develop the future-oriented industrial and social demand, not just arguing for the uselessness of the survey of industry demand in engineering education.

Due to the expansion of rolling admissions and diversification of college admissions, the widening gap between the level of scholastic ability and academic performance is the reality of college education. Thus, based on the incoming class of College A, this study analyzes the correlation between incoming students who enrolled in a college mathematics course during their first semester. Through this analysis, this study searches for a way to efficiently instruct students from various learning backgrounds when enrolled in the same course. Also, this study searches for a solution to lower the deviation of college mathematics' academic performance among engineering majors by examining the efficiency of a joint managed college mathematics curriculum.

The aim of this paper is to explore various ways to utilize critical thinking in engineering education. To this end, this paper, in the light of the relationship between critical thinking and the program learning performance of ABEEK, reviews engineering design education, engineering ethics education, and engineering communication education, which are major areas where critical thinking can be utilized in engineering education. As a result, it was confirmed that critical thinking skills, especially the elements and criteria of critical thinking, can contribute to the creative problem-solving process in engineering design education, the rational decision-making process in engineering ethics education, and the effective communication process in engineering communication education.
