This paper diagnose subjects and measures the learning ability of students based on the goal of developing an assessment tool for education productivity based on multi-aspect evaluation conducted by ICEE at Honam University. Furthermore, develop an assessment tool for education productivity that provides a motive to bring detailed improvements in teaching methods through the diagnosis. In addition, a method for compensating the issues and improving the quality of subject is suggested to develop learning ability of students through applying the assessment tool. An integrated operated system of CQI is desired to be built along with quality improvement of education through measuring academic quality by studying the methods for enhancing academic and learning ability achievement from analysis of the curriculum provided in the "ABEEK program". Through this study the current state of education productivity is presented through analyzing the difference between students who participated in the "ABEEK program" and who did not participate, and operating a comparison between the student's comprehension on their majors and liberal arts by the multi-aspect evaluation that has been conducted for 2 years.

Electronics machines make daily human life more convenient and comfortable and try to ease burdens. When designing and manufacturing such mechatronic systems, the engineers need to have a wide range of knowledge. The purpose of our education is for students to learn to use mechatronic techniques. To realize our goal, we regard "an interest in creation" of our student as an important educational method. In this paper, we propose and try an educational method for mechatronics creation using "their interest". The method is to hold robot competitions between 1st and 3rd year students as a regular curriculum. In order to confirm the progress of our students in our engineering course, in the last year, some students entered the Rescue Robot Contest held in Kobe Japan. As a result, our student team got second place, a great honor considering it was our first attempt. We confirm that the robot competition is a useful method to make students study by themselves.

Integration is an important intellectual ability to reconfigure several separated elements into one unified form and to concisely and categorically express them. In this paper, we classify the types of integration in C language, and propose a systematic and incremental method to transform to better code based on the integration types. This transformation method could also be used as a means to improve integrated thinking and efficiently learn C language, and will improve development ability in C programming or other language programming.

This research determined priority of quality improvement of public institution's education service by using ASC for importance and applying Topsis, a multi-standard decision-making method simplifying various attributes and scales of evaluation items and deciding the comparative priority for satisfaction and discussed the differences so as to measure the quality of public institution's educational service and examine the priority of education service' quality improvement. This research classified the characteristics of quality improvement. As a result, it's significant to suggest positive direction and method to improve satisfaction and education service's quality from an angle of demander by analyzing educational satisfaction of education service quality of public education institution and effects on the following improvement.

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 purpose of this study is to explore the possibility of changing students' learning styles and preferred teaching styles after applying the flipped learning method to engineering education. In order to achieve the purpose of this study, literature review and survey study were conducted. The subject of application of the flipped learning method is the 'Creative Problem Solving Methodology' class, which is one of the specialized liberal arts subjects operated for students of the college of engineering at D university in Gyeonggi-do. For the survey study, a tool adapted to the domestic conditions of Kolb's learning style test tool and Felder & Silverman's preferred teaching style test tool was used. In addition, pre- and post-tests were conducted to measure changes in the learning styles and preferred teaching styles. As a result of applying the flipped learning method for one semester, the learning style showed a tendency to change from an accommodative to a divergent learner. In addition, in the case of the preferred teaching styles, it was confirmed that there were statistically significant changes in the organization and the area of participation. Based on these findings, a proposal for a follow-up study was presented.

Linear motor can be directly applied to the system needed linear motions without rotary motions. To control high-speed and high-resolution, the development of the linear motors is recently required in the high-integrated and speed process industry This paper presents thermal and vibration analyses as well as measurement standards of the newly developed linear motors through analyzing the thermal behaviors and vibration characteristics of the advanced products. The thermal measurements are conducted for comparing the developed linear motor with the advanced linear motor and the Finite Volume Method(FVM) is used to identify the measurement results. And then the vibration measurement are carried out in the developed and advanced linear motors with respect to the speed. To identify the measurement results, the Finite Element Method is utilized in the developed and advanced linear motors, respectively. The FVM, FEM, and experiments make it possible to understand these characteristics. The improvement is suggested through their results conducted experiment and analyses.

Large-size graphene samples are successfully prepared by combining ultrosonic assisted liquid phase exfoliation process with oxidation-deoxidation method. Different from previous works, we used an ultrasound-treated expanded graphite as the raw material and prepared the graphene via a facile oxidation-reduction reaction. Results of X-ray diffraction and Raman spectroscopy confirm the crystal structure of the as-prepared graphene. Scanning electron microscopy images show that this kind of graphene has a large size (with a diameter over $100{\mu}m$), larger than the graphene from graphite powder and flake graphite prepared through single oxidation-deoxidation method. Transmission electron microscopy results also reveal the thin layers of the prepared graphene (number of layers ${\leq}3$). Furthermore, the importance of preprocessing the raw materials is also proven. Therefore, this method is an attractive way for preparing graphene with large size.

Most available methods of facial gender recognition work well under a constrained situation, but the performances of these methods have decreased significantly when they are implemented under unconstrained environments. In this paper, a method via low-rank and collaborative representation is proposed for facial gender recognition in the wild. Firstly, the low-rank decomposition is applied to the face image to minimize the negative effect caused by various corruptions and dynamical illuminations in an unconstrained environment. And, we employ the collaborative representation to be as the classifier, which using the much weaker $l_2-norm$ sparsity constraint to achieve similar classification results but with significantly lower complexity. The proposed method combines the low-rank and collaborative representation to an organic whole to solve the task of facial gender recognition under unconstrained environments. Extensive experiments on three benchmarks including AR, CAS-PERL and YouTube are conducted to show the effectiveness of the proposed method. Compared with several state-of-the-art algorithms, our method has overwhelming superiority in the aspects of accuracy and robustness.
