Objective: This study aimed to identify the different wind speed categories and competitive level among windsurfers through GPS variables to provide the useful information on the development of training programs for enhancing windsurfers' performance. Method: Data from 69 female athletes who participated in 27 races during the 2018-2019 windsurfing season were used for the analysis. Average board speed, total race time, total distance, upwind race time, downwind race time, beam reach race time were collected through GPS. Unconfirmed data were excluded along with penalty point data. The wind conditions were classified as light, light to medium, medium, medium to heavy, and heavy wind, the competitive levels were classified as level 1, level 2, and level 3. Results: As for the average board speed, the level 1 or level 2 group showed higher board speed than the level 3 group in all wind conditions except for the light wind. The total race time and upwind race time showed less time in level 1 or level 2 group than level 3 group in all wind conditions. The total distance, downwind race time and beam reach race time showed less distance and time in level1 group than level 3 group under sufficient wind conditions. Conclusion: Our results show that the aerobic capacity to sustain pumping during upwind course in wind conditions below 15 kts effects performance. In wind conditions of 15 kts or more, indicated that the board control for the fast board speed and small distance required during up, down, beam reach courses had an effect on competition performance. This information can be provided to windsurfers and coaching as basic data for training programs to improve performance.

The needs for change in the traditional on engineering education system in Korea have been evoked since 1998 when the Accreditation Board for Engineering Education of Korea (ABEEK) was about to be established. The engineering college at Yeungnam University has been one of the most active members in the Korean higher education institutions which participated in the ABEEK movement at the earliest stage. This paper reports the efforts made by Yeungnam University in preparing for the trial accreditation of engineering programs for the first time in Korea. The reformation and restructuring were made in many areas in order to establish the self-improving circulative engineering education system. The accreditation criteria were thoroughly investigated, and reforms were made in individual programs based on the critical assessment of existing system. The contents of educational reform and the experience during the trial accreditation process are summarized and discussed.

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.

This study investigated the purpose of commissioned on-board training and the legal basis for the management of commissioned on-board trainees, focusing on the seafarer educational institution belonging to the Ministry of Education, which cultivates merchant mariners. A program was developed based on this research. Despite the legal basis for the management of commissioned on-board trainees, satisfaction with on-board training management has not been high, and the on-board trainee management system of the university was poor. As a result safety accidents among commissioned on-board trainees occurred on ships, and a few students abandoned on-board training. An I.M.S.A.R. model has been developed for safe and systematic management of commissioned on-board trainees, and a base for a human resource management program for commissioned on-board trainees has also been developed. This study is meaningful in that it derived a practical plan for the management of commissioned on-board trainees.

There is a growing interest in gastroenterology and hepatology fellowship training in Korea and other countries. The Korean Society of Gastroenterology held an international symposium for gastroenterology and hepatology fellowship training, titled, "GI Fellow Training in Asia-Pacific Countries" on April 14, 2018. The Japanese education system was different for each hospital. The American societies for gastroenterology set up their education system together and have continued with frequent modification. The Taiwan and Singapore education systems are well organized and localized. We need a well-organized and sustainable education system for gastroenterology and hepatology fellowship training suitable for Korea.

This paper analyzes the current state of operation and the effect of introduction of the single accreditation system, which was fully introduced in 2016 by the Accreditation Board of Engineering Education Korea(ABEEK). Because Engineering Education Accreditation are program-based certification, and department operates accreditation programs and non-accreditation programs, if a student under the accreditation program fails to graduate from the accreditation program, he or she must complete the transfer to a non-accreditation program at least one year before graduation. Since 2016, when the single accreditation system was introduced, freshmen of department have allowed non-accreditation graduation only for reasons prescribed separately by the program's regulations or guidelines. In order to identify and reflect the operational status and effectiveness of the single accreditation system in the 2020 accreditation review, ABEEK conducted a complete survey on the current status of graduates in February 2020 among 157 programs at 26 universities receiving the 2020 accreditation review. The results of this study are expected to be used as basic data for the improvement of the single accreditation system in the future by examining the effects of the single accreditation system implemented after 2016 and considering the problems at the site due to the introduction of the single accreditation system of programs that ABEEK had not previously expected.

As the convergence solutions become more common, the use of Arduino and Raspberry Pi boards has been increasing. These control boards has to be executed under power blackout. In this environment, we take advantage of solar power system to overcome the power out. In this paper, we poposed a effficient power control strategy. Our experimental device is a DSLR shooting device executed based a predesigned interval time. The control module of our experimental device is the compound system of Raspberry Pi and Arduino boards. Arduino board send the force signals to wake up Raspberry Pi. We developed a new control strategy algorithm for the efficient use of solar power energy. In this paper, we mesured the efficiency of solar enery consuming of our system. We programmed a control system to send DSLR shooting signals. In experimentals, we ensured a stable consuming of electricity during 10 days. In the end, it was found that the consumption power of the Raspberry was reduced by about 81% when the Aduino was combined to save power.
