본 연구의 목적은 메타버스 기반 비대면 수업에서 학습만족도와 지속이용의도에 영향을 미치는 요인을 찾아내는데 있다. 이를 위해 기술수용모형과 정보시스템 성공모형을 토대로 가설을 세우고, 메타버스 플랫폼 중 게더타운을 이용한 수업 경험이 있는 학생을 대상으로 2021년 11월 22일에서 2022년 1월 3일까지 온라인과 오프라인을 기반으로 설문조사를 실시하여 불성실한 응답을 한 설문지를 제외하고 122부를 대상으로 PLS 구조방정식을 이용하여 분석 하였다. 분석결과 플랫폼 품질요인 모두 용이성에 영향을 미치지만, 유용성에서는 콘텐츠 품질만 영향을 가지고 있었다. 용이성은 유용성에 영향을 미치고, 유용성과 용이성이 학습만족도에, 유용성과 학습만족도가 지속이 용의도에 정(+)의 영향을 가지고 있었다. 본 연구의 의의는 메타버스 기반 비대면 수업에서 학습만족도와 지속이용의도에 영향을 미치는 변수를 실증적으로 분석하였다는 점에 있다. 후속 연구에서는 게더타운을 비롯한 다양한 메타버스 기반 플랫폼을 대상으로 학습만족도와 지속이용의도에 영향을 미치는 변수들에 대한 추가 연구가 필요하다.

This paper investigates a new approach for Li-Ion battery state-of-charge (SOC) estimation using sliding mode observer (SMO) technique including parameters aging compensation via recursive least squares (RLS). The main advantages of this approach would be low computational load, easiness of implementation along with the robustness of the method for internal battery model parameters estimation. The proposed algorithm was first tested on a set of acquired battery data using implementation in Simulink and later developed as C-code module for firmware application.

A stock removal cycle is developed as a programming tool of the CNC lathe. This cycle support the easiness and swifness of a part program generation in the shopfloor. The cycle contains the function of tool path generation of rough/finish cutting, of avoidance air-cut for non-cylindrical (die-casted, forged) workpiece, and of the tool collisopn detection/aviodance. Consequently the intelligent stock removal cycle results in improving the productivity and safety of CNC lathe.

In this paper, the prototyping process for developing syllable-initial consonant-based game 'Korean Guards' is described. Users may effectively learn Korean words using alphabetically sequential approaches, but the easiness of access bestowed on the smart environments and game algorithms could be fully utilized for the functional advantages for educational purposes. This functional game is developed on Android OS and the prototypical outcome is shown.

It is well known that robust compensators designed by the block-diagonal Lyapunov function approaches are conservative while they are popular in practice because of their computational easiness. In this note, we develop a systematized version of conventional block-diagonal Lyapunov function approaches by deriving two separated optimizations based on the guaranteed cost control method. The proposed method generates reasonable robust compensators in practice.

Two control algorithms of active suspension system for improving ride quality are described and their effectiveness is assessed using a quarter car model. Optimal control approach demonstrates great flexibility to meet various running conditions of a vehicle. However, in order to fully utilize the power of optimal control apporach, accurate estimation of the state variables is essential. Simple, yet effective sky-hook algorithm seems to be well suited for real application because of its much relaxed requirements on sensing the stste variables and relative easiness to implment.

Proposed herein is a shape design of a different rail support block with existing ones for the commercialization of the urban maglev. The rail support for existing test lines adopts monoblock steel sleeper, whereas an individual support system has been proposed to achieve an additional cost savings and to provide an emergency exit. Also, to enhance the easiness of installation and the repairability, alignment adjusting methods suitable for the new design have been devised.

In this paper, we investigate possible scrambling methods for the JPEG(Joint Photographic Export Group) still image compression standard. In particular, we compare the conventional line rotation and line permutation methods to the DCT block scrambling in terms of the number of bits to be increased and the easiness of buffer control. Computer simulation results show that the DCT block scrambling method is suitable for both data security and buffer control in one-chip JPEG applications.

This study describes the development of nursing education program on web-based instruction for Nursing Management Practice of nursing school. The program has been developed based on five steps of the teaching-learning design model developed by Chung, In-Sung which is widely used in Web-Based Instruction(WBI). The objective of this study was to develop nursing education program on WEI and to evaluate its effectiveness. The subjects consisted of twenty-four senior nursing students taking the Nursing Management Practice course. Two sets of questionnaires were used for this study. They were asked to evaluate the program in terms of appropriateness of the teaching strategy, precision of the contents, easiness of use, easiness of approaching system, interface design, system management, enhancement of communication, and effectiveness of learning. The program was developed in five steps, analysis of the student, design of the contents, production of the system, implementation of the system, and evaluation of the effectiveness. It is concluded that this program was very useful in increasing the effectiveness of learning and motivation in the students. In addition to this, the web-based learning system would be one of the best qualified educational method for nursing students. Therefore, I would suggest that it can be used for other nursing courses which is available on the Web.
