In the engineering students, MSC is the most important basic areas in education. Also, the calculus is a main subject in the MSC. So calculus has been operating the annual number of courses at the university. We introduced the concept of joint control ; the joint syllabus, test and assessment. In harsh conditions to maintain joint control system of the calculus, we built a computer-aided-system to manage web-based result processing system. In this paper, we discussed the necessity and effectiveness of joint control system for calculus.

In engineering education practical experiments is very important for each student, but due to the limitation of time and available resources such as laboratory equipment, space and instructors enough hands-on real experiments could not be provided to all students enrolled in the program throughout the academic year. In this sense web-based remote experiments through internet become a solution for engineering education and an emerging new paradigm for students and teachers. This paper presents the development of the web-based remote vibration experiment system for mechatronics education. Students can access this experimental equipment through an internet and conduct vibration experiment remotely without any restriction on time and place. IP address for data communication and web-service are assigned in local computer and then students receive experimental results and the captured pictures using network. The developed system provides real-time feedback of the tested results. Ubiquitous access to the system gained popularity from students.

In this paper, a detuning factor (DeFac) method is proposed to design the key parameters for optimizing the transfer power and efficiency of an Inductively Coupled Power Transfer (ICPT) system with primary-secondary side compensation. Depending on the robustness of the system, the DeFac method can guarantee the stability of the transfer power and efficiency of an ICPT system within a certain range of resistive-capacitive or resistive-inductive loads. A MATLAB-Simulink model of a ICPT system was built to assess the system's main evaluation criteria, namely its maximum power ratio (PR) and efficiency, in terms of different approaches. In addition, a magnetic field simulation model was built using Ansoft to specify the leakage flux and current density. Simulation results show that both the maximum PR and efficiency of the ICPT system can reach almost 70% despite the severe detuning imposed by the DeFac method. The system also exhibited low levels of leakage flux and a high current density. Experimental results confirmed the validity and feasibility of an ICPT system using DeFac-designed parameters.

As amount of information in construction industry is growing, the role of information system in project management is becoming increasingly important. With the emerging IT application to the advancing construction industry, construction project management system with advanced technology has been progressed vigorously to improve construction productivity and management efficiency. Recently, a web-based Project Management Information System (PMIS) is developed to support decision-making process by efficiently managing project related information generated from various discipline. Many firms are in the process of developing the PMIS system or already have been applied the system to various projects. However, PMIS is still in its early stage of development to be applied at industrial plant construction projects that process management is significantly emphasized for the successful execution of the project. With the complexity of the industrial plant projects, the industry practitioners need to be able to visualize the construction schedule information to manage the project efficiently. This study suggests methodologies for improving PMIS specialized for industrial plant piping construction projects to estimate the baseline schedule and performance measurement more accurately by developing a framework for the piping construction projects. By using this developed system, the researchers expect that piping construction projects will be more efficiently managed on a real-time basis through measuring progress of piping at each and every state of progress milestone and provide management with opportunities to forecast the level of efforts required to execute the remaining work scope in a timely manner

After the Se-wol ferry disaster in Korea, the safety issue was highly spotlighted in a number of media, and consequently the ministry of public safety and security was newly established under the public attention. In addition to this, a recent earthquake in Gyeonju suggested the training issues for public such as evacuation and public safety. Regarding the industry, one of significant reasons causing the accidents were inadequate training, in execution of safety manual or inexperienced first response. Although the engineering or scientific study provided a basis of the industry safety and health in Korea a study focusing on the safety and health education system should be highlighted in that the law is the only way to execute the policy. In this manner, the goal of current study was to compare the safety and health education system in Korea to other countries including America, England and Germany. Especially, the law for training method, contents, supervision and punishment was analyzed. Result showed (1) lack of a structured training course for educating safety and health education trainer, (2) no training system of safety and health education to public or workers, and (3) less specific law for supervision and punishment as compared to the America, England and Germany.

코로나19 팬데믹을 지나면서 동영상 수업과 실시간 온라인 교육은 활성화되었지만 교수자와 학습자 간의 상호작용 부족 문제는 여전히 해결해야 할 과제로 남아 있다. 본 논문은 실시간 온라인 수업의 교육 효과와 만족도를 높이는데 중요한 역할을 하는 상호작용의 문제를 개선하기 위해 디지털 휴먼을 활용하는 학습지원 시스템을 설계하고 구현한다. 본 논문에서 디지털 휴먼은 수업에 참여하는 가상의 학습자로서 다른 학습자들이 익명 채팅 시스템을 통해 등록한 질문을 교수자에게 대신 질문해 준다. 또한, 수업의 조력자로서 교수자가 강의하는 음성 메시지를 실시간으로 분석하여 학습자에게 수업의 요약본 형태로 제공함으로써 상호작용을 촉진한다. 제안한 시스템이 실제 온라인 실시간 수업에 활용 가능한지 검증하기 위해 Zoom 수업에 적용한다. 실험 결과 디지털 휴먼 기반의 학습지원시스템을 통하여 촉진된 질의응답과 실시간 수업 요약이 성공적으로 제공됨을 보인다.

Capstone design education is essential in the engineering design process according to the certification standards of ABEEK. Capstone design process should be properly trained in undergraduate courses in order to increase the design ability of systems, components and processes within realistic constraints. In this study, a modified design model as a capstone design education model was proposed to reduce the separation between the design process at industrial sites and the design process at university education. The modified design model based on 6-sigma methodology is composed of 6 design steps such as define, measure, analyse, design, verify, and report. Each step has appropriated design contents and tools, and is configured to generate design results. The proposed design model was directly applied to the capstone design class for automotive engineering in Kunsan National University, and it was confirmed that the proposed DMADVR methodology was a very useful design education model to enhance the design ability, teamwork ability and communication skills required by ABEEK.
