This paper proposes a multiple switch mode power supply (SMPS) system based on the wireless network which controls variable load. The system enables power supply of up to 600W using 200W SMPS as a unit module and provides a controlling function of output power based on variable load and a monitoring function based on wireless network. The controlling function for output power measures the variation of output power and facilitates efficient power supply by controlling output power based on the measured variation value. The monitoring function guarantees a stable power supply by observing the multiple SMPS system in real time via wireless network. The performance of the proposed system was examined by various experiments. In addition, it was verified through standardized test of Korea Testing Certification. The results were given and discussed.

The purpose of this study is to derive implications for establishing vocational training education policies in Korea by investigating COVID-19 countermeasures in the United States, Germany, Switzerland, Australia, the United Kingdom, and Singapore, which are representative vocational education training countries. The implications derived from the survey of leading countries in vocational education training are as follows. First, in order to respond to COVID-19, face-to-face vocational education training was quickly converted to online education. Second, the system was strengthened to overcome the crisis of the apprenticeship system, especially the British and Australian governments established a special budget for the apprenticeship system. Third, due to COVID-19, blended learning has become a new standard education model, accelerating the digitalization of vocational education training. Finally, leading countries in vocational education training are promoting the development of the edutech industry to support online education. This provides important implications for the direction of change in vocational education training in South Korea.

The objective of the current study is to establish the CQI procedure of leadership outcome education, which is emphasized in engineering education accreditation. Leadership includes many program outcomes, especially soft skills, such as communication skill, team work skill, and etc. This paper studied leadership education program in Yeungnam University. In particular, this research was conducted by using focus group interviews with experts and working level staffs of relevant organizations for the analysis of Yeungnam University curriculum and non-curriculum courses related to leadership education and for the preparation of leadership education CQI method. In addition, we conducted leadership competence diagnosis, leadership education demand survey and satisfaction level survey on the leadership camp participants. Interviews with experts, lecturers and focus group of Dale Carnegie Research Institute Daegu branch that administered the progress of leadership camp were conducted along with analysis of education contents through non-participation observation method during camp period and participant students interviews. The conclusions are summed up as follows: To educate global leaders in true meaning, first, psychological level competence strengthening method and study completing ability improvement method should be considered simultaneously. In particular, for non-capital region universities, emphasis should be given to education for self-confidence and vision establishment. Second, leadership education methods of mid/long term and systematic curricular and extra-curricular type should be pursued. For instance, with the use of engineering design subject completing system, leadership education can be consolidated to engineering subject courses with engineering design projects or the system of mentor-pupil among earlier leadership camp participants and later participants may be utilized. Third, it is determined necessary to pursue and realize practical methods of conducting various intramural leadership related education activities in mid/long term perspective by organizing leadership education advisory group consisting of major, departments and intramural and extramural relevant organization authorities that focus on leadership education.

Since ABEEK ("Accreditation Board for Engineering Education of Korea") began its accreditation in 2001, the 595 programs in 100 institutions have been accredited, and now the number of accredited programs is continuously increasing. On the other hand, NCS ("National Competency Standards") which is directed by government, has been also introduced in recent years, and it becomes the center of attentions of many universities in Korea. Each of these 2 systems has its own strengths and weaknesses, even though their main purposes are very similar. This paper deals with the comparison between the curriculum based on NCS with ABEEK. And also, the examples of making the curriculum based on the NCS would be introduced. At the conclusion, some suggestions for the new NCS system would be proposed.

To enhance the excellence, effectiveness and economical efficiency in the learning process, we implement a hybrid educational system for engineering experiments where web-based virtual laboratory systems and distance education systems are properly integrated. In the first stage, we designed client/server distributed environment and developed web-based virtual laboratory systems for digital systems and electrical/electronic circuit experiments. The proposed virtual laboratory systems are composed of four important sessions and their management system: concept learning session, virtual experiment session, assessment session. With the aid of the management system every session is organically tied up together to achieve maximum learning efficiency. In the second stage, we have implemented efficient and cost-effective distant laboratory systems for practicing electric/electronic circuits, which can be used to eliminate the lack of reality occurred during virtual laboratory session. The use of simple and user-friendly design allows a large number of people to access our distant laboratory systems easily. Thus, self-guided advanced training is available even if a lot of expensive equipment will not be provided in the on-campus laboratories. The proposed virtual/distant laboratory systems can be used in stand-alone fashion, but to enhance learning efficiency we integrated them and developed a hybrid educational system for engineering experiments. Our hybrid education system provides the learners with interactive learning environment and a new approach for the delivery of engineering experiments.

Site response analysis is an important topic in earthquake engineering. A time-domain numerical method called as one-dimensional (1D) finite element artificial boundary method is proposed to simulate the homogeneous plane elastic wave propagation in a layered half space subjected to the obliquely incident plane body wave. In this method, an exact artificial boundary condition combining the absorbing boundary condition with the inputting boundary condition is developed to model the wave absorption and input effects of the truncated half space under layer system. The spatially two-dimensional (2D) problem consisting of the layer system with the artificial boundary condition is transformed equivalently into a 1D one along the vertical direction according to Snell's law. The resulting 1D problem is solved by the finite element method with a new explicit time integration algorithm. The 1D finite element artificial boundary method is verified by analyzing two engineering sites in time domain and by comparing with the frequency-domain transfer matrix method with fast Fourier transform.
