Teachers, who are the subject of on-site training, cannot create education content easily reflecting their experience for themselves, and also cannot distribute the content to leaners. Even though the content is distributed, there are limited in available devices as well as representable content features. So, an applicable authoring tool is needed at the user level. In this paper, we propose an authoring tool by which users and teachers can make education content easier based on WYSIWYG interface, and can distribute that. The proposed authoring tool supports various media education content of XML format so that viewers on various smart devices can see the content regardless of operating systems. And not only we conduct survey of users to evaluate convenience and expression of proposed authoring tool, but also we check whether the content can be equally visualized on various smart devices.

The research goals of this study using the wind by car as replaceable energy are summarized to three things as follows. The first goal is to secure a replaceable energy source of environmental conveniency through the wind power system by the wind by car. The second goal is to develop a educational program for related convergence professional man. The third goal is to make a wind power system for a replaceable energy education. We have performed for obtaining a research goal during six months. So, we concluded three results as follows. The system for doing a wind by car is modeled. New convergence educational program for department of electrical, electronic, mechanical engineering is developed under this system. And, the wind power system is produced for practice education of demonstration for replaceable energy.

Universities should provide experiential learning in subject and non-course subjects so that students can graduate with job competency related to their major and the experiential learning includes capstone design implemented on campus and field training conducted by companies. In particular, the decrease in industry participation in short-term (4 weeks) and mid-term field training (8 weeks) due to the implementation of standard field training introduced from the second half of 2021 is making it more difficult for students to gain practical experience. To solve this problem, in this paper, we propose an industry-participatory capstone design & field practice linkage model that combines capstone design and professional practice to solve the technical difficulties of companies. Participating students find solutions to corporate difficulties in the capstone design process and produce prototypes for solutions during the field practice period, focusing on the case of the department of electronic engineering at Gyeongbuk Y University. We believe that it is one of the good models of industry-university cooperation education in which universities and industries win-win.

In this paper, VR smart factory XR content tailored to process execution scenarios was produced to reflect the characteristics of XR content, which is highly dependent on HDM, unlike general-purpose content software for UX/UI design and usability evaluation of digital twin-based XR content in manufacturing. HMD equipment called Qculus Quest2 was used to perform the process execution task scenario for XR content, and content production was made through Unity Engine and SteamVR Plugin.

본 연구는 디지털 잉크를 통해 웹 프레젠테이션을 제작하는 인터페이스를 제안한다. 온라인 환경에서 다수의 사용자들이 적절한 시간과 장소에서 프레젠테이션을 들을 수 있는 웹 프레젠테이션 시스템의 역할이 더욱 증대될 것으로 예상되는 가운데, 프레젠테이션 의도를 보다 명확히 전달하면서 이에 따르는 비용과 수고를 최소로 하는 프레젠테이션 시스템에 대한 연구가 더욱 요구되고 있다. 이를 위해 우리는 사용자에게 가장 친숙한 #Pencil & Paper# 방식인 디지털 잉크 인터페이스를 기반으로 가상 프레젠터의 애니메이션 효과를 증강하고, 프레젠터와 사용자간의 상호작용을 지원하는 웹 프레젠테이션 시스템을 제안하게 되었다. 이는 실제 프레젠테이션이 가진 장점들을 살리면서 보다 많은 사용자들이 쉽게 접근할 수 있는 장점을 가지고 있다. 제안 기법은 온라인 교육이나 전자 책, 지능형 교육 시스템, 다양한 가상환경에도 쉽게 확대 적용될 수 있을 것으로 기대된다.

Even though we basically regard spoken English like listening and speaking rather than written language as an important principle in Elementary Education of English, actually students are being taught English only by imitating what they heard and watched through audio or video tapes in the scene of elementary school. Of course, it is successful to learn English focused on a spoken language not in EFL(English as a foreign language) but in ESL(English as a second language) circumstance. Therefore, we provide products of multimedia contents in order to give opportunities which can make use of English in the classroom through the Web in this paper. In addition to it, we write this paper on method to strengthen motivation for learning language even out of the classroom by putting English to practical use through video conference system or E-mail exchange.

Conventional one-way cramming education at schools has the disadvantage of poor student interest in learning, immersion, and learning efficiency as well as a limitation in realizing collective intelligence and collaborative learning. Therefore, an educational content service platform using a near-field communication(NFC) technology is required as a tool for encouraging the voluntary learning participation of students and increasing learning effectiveness through self-directed studying. This study focuses on the development of an educational content production system that creates high-quality education contents suitable for smart schools. In these schools, students and teachers generally communicate through an electronic blackboard using Bluetooth, which is an NFC technology. Further, the lecture notes of individual students are reproduced and collected as big data, which will facilitate the sharing of these notes.

In this paper, we propose a controller gain based on model based design and implement the two-wheel inverted pendulum type robot using NXT Lego and RobotC language. Two-wheel inverted pendulum robot consists of NXT mindstorm, servo DC motor with encoder, gyro sensor, and accelerometer sensor. We measurement wheel angle using bulit-in encoder and calculate wheel angle speed using moving average method. Gyro measures body angular velocity and accelerometer measures body pitch angle. We calculate body angle with complementary filter using gyro and accelerometer sensor. The control gain is a weighted value for wheel angle, wheel angular velocity, body pitch angle, and body pich angular velocity, respectively. We experiment and observe the effect of two-wheel inverted pendulum with respect to change of control gains.

We studied the perceived creative ability, convergent thinking and creative leadership related to converged capabilities among students who participated in the capstone design and graduation works and those who did not participate. In creative ability, students who participated capstone design and graduation works need more curriculum and non-curriculum activities for the idea generation through the understanding of various majors, but overall, they achieved higher positive results than the nonparticipating students. For creative leadership and convergent thinking, students with capstone design and graduation works showed a more positive capabilities, while students with nonparticipating students showed a slightly lack of creative thinking of higher order thinking, the logical analysis of complex phenomena, and overall understanding.
