The core purpose of the system proposed in this paper is to help learners pursue proactive and self-oriented education by allowing learners to proactively configure their own content, that is, learners no longer have to be restricted by prescribed sequence of lectures. Although a variety of standardization and Learning Management System (LMS) were produced to develop and effectively manage web contents in response to active diffusion of internet application, practical changes to assist online learners are not yet to be found. In this paper, I would like to introduce a LMS that can support self-leading education by providing various types of learners at Virtual University with delicately organized educational contents for maximum efficiency. The system allows a learner to select a lecture or a chapter which has been presorted to meet his educational needs and intellectual ability. In general, most LMSs cannot meet every individual's educational needs because they structure their programs by letting learners simply choose from a list of available lectures at prescribed level or difficulty. However the Self-Leading LMS eliminates such boundaries by allowing learners to choose contents and difficulty within the limit set by their own educational competence.

The purpose of this study is to explore improvable proposal of instruction through analyzing learners' needs and satisfaction for college of engineering. Based on the online survey date with undergraduate students in Seoul National University, recognition difference between students in college of engineering and all students in SNU was identified. Among several factors influenced on learners' satisfaction in class, it is shown that satisfaction to facilities is higher than any other factor related to instruction. Generally, satisfaction with teaching in class is lower while satisfaction to an extrinsic support to students is high. Therefore, instructors should be more concerned about teaching in class. Learners' satisfaction with instructors' feedback to assignments and tests is significantly higher in college of engineering. However, learners' satisfaction with the progress of classwork and assignment students should perform regularly is lower than one in other colleges.

This study analyzes the performance of flipped learning, an offline class method conducted in a degree-linked work-learning parallel system. Training in the work-study parallel system, which is conducted as part of job competency improvement, has thoroughly adhered to the offline method, but in line with COVID-19, unlike before, it is changing in the direction of using the online method more actively. However, educational methods such as flipped learning are not new because the degree-linked operation is applied to the academic system and education method of universities and is practically the same form as general university education. Therefore, it is necessary to analyze the educational performance and complementary points of flipped learning, which has recently been expanded in the degree-linked work-study parallel system, considering the characteristics of this system, in which classes are held only on weekends. As a result of statistical analysis based on the survey, some of the outcomes of flipped learning have been confirmed, and in order to increase the performances, it is necessary to continuously seek out specific measures to encourage learning and expand communication between instructors and students.

In this study, a software education program based on blended learning using scratch was designed for pre-service elementary teachers' software education. Software education program was applied to experimental group and control group within the university of education using Scratch programming for 12 weeks. Blended learning using online lectures was applied to experimental group. The pre-service teachers' recognition about software education and self-evaluation of computational thinking were performed. Then, we analyzed the effect of the developed education program on the recognition of software education and computational thinking. As a result, the level of post-recognition of software education in the experimental group was significantly higher than that of the pre-recognition. In the self-evaluation of computational thinking, the experimental group was significantly higher than the control group. Therefore, it can be seen that the software education program based on blended learning can help improve the learner's computational thinking.

This paper proposed a novel high performance sensorless control scheme for IPMSM based on an extended nonlinear state observer. The gain-matrix of the observer has been derived by using state linearization method. Steady state errors in estimated rotor position and speed due to parameter inaccuracy have been analyzed, and an equivalent flux error is defined to represent the overall effect of parameter errors contributing to the wrong convergence of the estimated rotor speed as well as rotor position. Then, an online compensation strategy was proposed to limit the estimation errors in rotor position and speed. The effectiveness of the extended nonlinear state observer is validated through simulation and experimental test.

Whether the engineering department of universities employs ideal usage of e-learning or not needs to be investigated as many engineering departments diversify the use of the e-learning elements for educational purpose. Applying the teaching and learning methods and characteristics would lead to better strategies which are applied to development of contents and deployment of the e-learning courses. This study examines the characteristics and approaches of the usage of e-learning elements used by some instructors who use multimedia contents in offline teaching and learning environment. The results of this study shows that the e-learning elements assist the face-to-face course and the interactions are manifested in the classroom rather than in online setting. Lecture, hands-on-practice, simulation, and PBL(Problem-based learning) are turned out to be the major teaching and learning methods. This study signifies the need for use of various teaching and learning methods by the instructors and provision of PBL environment.

Recently, MOOC (Massive Open Online Course), which has the characteristics of open content, has been changing the paradigm of university education as it is being serviced by various universities. In addition, MOOC based e-learning service has been developed into various types. The quality management of MOOC-based e-learning services has been studied on the general factors provided by MOOC regardless of MOOC type so far. In this study, we propose a method to improve the quality management of MOOC - based e - learning service by analyzing the factors affecting the quality of e - learning service by MOOC type.

Various linguistic knowledge resources are required in order that machine can understand diverse variation in natural languages. This paper aims to devise an automatic construction method of linguistic resources by reflecting characteristics of online contents toward continuous expansion. Especially we focused to build NE(Named-Entity) dictionary because the applicability of NEs is very high in linguistic analysis processes. Based on the investigation on Korean Wikipedia, we suggested an efficient construction method of NE dictionary using the syntactic patterns and structural features such as metadatas.

The purpose of this study is to analyze the effectiveness and necessity of improvement for the currently implemented education and training in order to cultivate and secure excellent construction engineers of domestic construction companies, and to suggest future improvement measures. The conclusions obtained through this study are as follows. The overall satisfaction of construction engineers at the construction site was high, and it was found to be effective in improving job skills, but the educational content, educational methods, and educational environment need to be improved. In order to improve the educational content, it is urgent to introduce a practical-oriented educational curriculum to respond to technological development. In order to increase the educational effect of online education methods, it is very important to develop excellent educational content. In order to improve the educational environment, it is necessary to expand customized practice spaces, establish educational facilities by region, and operate shuttle buses.
