A pre-feasibility test is done for renewable energy hybrid power systems at off~grid islands in which the current power supply is provided only by diesel generation. We apply Homer (Hybrid Optimization Model for Electric Renewables) which was developed by the National Renewable Energy Laboratory (NREL) for the analysis to identify the cost-minimizing combination of power generating facilities for the given load profiles. Chuja-Do, Geomun-Do and Youngsan-Do have been selected for our analysis considering the wind resources data of the Korea Institute of Energy Research (KIER). Information on wind speed, solar radiation and temperature is also used for the analysis. System component cost information from overseas market has been used due to the lack of domestic information. Site specific Load profile for electricity demand for those islands are reconstructed based on the partial survey results obtained form other sources. The LCOE of the least cost hybrid power systems for Chuja-Do, Geomun-Do and Youngsan-Do are $0.278/kWh, $0.234/kWh and $0.353/kWh, respectively Considering the fact that diesel generation is being subsidized at the price of $0.300/kWh by the government, first 2 cases are economically feasible for the introduction of renewable energy hybrid systems to those islands. But the third case of Youngsan-Do does not meet the criteria. The basic differences of these pre-feasibility test results are from the differences of the site specific renewable energy conditions, especially wind resources. In summary, promoting hybrid systems in the off-grid remote island should be based on the economic feasibility test results. Not all the off-grid islands are feasible for introducing this renewable energy hybrid system.

This study was conducted to investigate the status of oral health behavior according to economic inequality in Korea. Raw data for the 3rd year (2015) of the 6th national health and nutrition survey were analyzed. Among surveyed individuals, adults over the age of 19 were designated as research subjects. The results indicated that a smaller 'house income' was associated with a higher supply and demand experience for basic living and a higher DMFT. Additionally, a higher DMFT was associated with a lower 'house income', lower 'education level', and the 'experience of basic living security received'. Oral health behavior inequality was caused by economic inequality. Overall, these results indicate that it is necessary for the oral health service of vulnerable groups to strengthen preventive activities through comprehensive arbitration policies regarding the social decision factors of public health projects.

This study is to analyze teacher's recognition and needs of STEAM education in specialized high schools for technical fields. For this study, survey using questionnaire was applied to teachers in specialized high schools for technical fields. This study includes the recognition and the needs on STEAM education of general and industrial subject teachers in specialized high schools for technical fields. In order to carry on this study, 655 questionnaires were collected from teachers of 16 specialized high schools for technical fields in the whole country. Practically, 611 questionnaires (257 of normal subject teachers and 398 of industrial subject teachers) were used for this study. As a result, it is known that the needs of STEAM education is larger to industrial subject teachers than general subject teachers. But it is disclosed that STEAM education is more difficult to general subject teachers than industrial subject teachers. In requirements of teaching-learning, general subject teachers only required reference materials, but industrial subject teachers needed STEAM lesson under the same subjects and data sharing system as a priority. General and industrial subject teachers also considered education program development for creative thinking skills and problem solving abilities as a priority. Finally, in the administrative and financial requirement, both of them demand to reduce administrative tasks as a priority.

Since the development of NCS-based curriculum in field of game education is not well studied, so we carried out research on the curriculum development of game contents department of Kimpo University as the first study to link game education and NCS. In order to develop the NCS-based game education course, we analyzed the game industry environment and conducted a demand survey on the game industry officials to derive the vocational basic subjects required for game contents creation. In addition, we analyzed the types of manpower training by using on-site experts (SME). SME also designed the NCS curriculum by matching the manpower type comparing with NCS classification and capacity unit, analyzing the usefulness of each Capacity unit, and finally, by arranging each NCS and non-NCS subjects by semester. This research is meaningful as the first study linking NCS and game content creation, and it will be a reference for other education institutions planning game education course based on NCS. It also can be used as a basic material for researching game education quality management (CQI) as well as improvement methods for future game education courses.

The eye tracking system designed in this paper is an eye-based computer input device designed to give an easy access for those who are uncomfortable with Lou Gehrig's or various muscle-related diseases. It is an eye-based-computer-using device for users whose potential demand alone amounts to 30,000. Combining the number of Lou Gehrig's patients in Korea estimated at around 1,700, and those who are unable to move their bodies due to various accidents or diseases. Because these eye input devices are intended for a small group of users, many types of commercial devices are available on the market. It is making them more expensive and difficult to use for these potential users, less accessible. For this reason, each individual's economic situation and individual experience with smart devices are slightly different. Therefore, making it difficult to access them in terms of cost or usability to use a commercial eye tracking system. Accordingly, attempts to improve accessibility to IT devices through low-cost but easy-to-use technologies are essential. Thus, this paper proposes a complementary superior performance eye tracking system that can be conveniently used by far more people and patients by improving the deficiencies of the existing system. Through voluntary VoCs(Voice of Customers) of users who have used different kinds of eye tracking systems that satisfies it through various usability tests, and we propose a reduced system that the amount of calculation to 1/15th, and eye-gaze tracking error rate to 0.5~1 degree under.

The significance of pilots' fatigue and the attributed risk management had continuously increased over time as the airline industry expanded. Research and legislation efforts associated with pilot fatigue are being taking place actively all over the world. In the developed world such as the United States and European Union etc., the airline pilot fatigue is already being managed by considering the show up time, the number of take offs and landings made, resting period, jet lag etc., when computing flight duty time. In Korea, the flight duty time is only limited by the total number of hours per given period regardless of the flight conditions and environment. Such lack of regulation demand development of a fatigue management program. According to the survey taken from the airline pilots in Korea, it has been found that acquiring foreign policies directly may in turn, increase the risk of fatigue. This research suggest future studies regarding fatigue management program adapted exclusively to Korean domestic flight environment and culture.

Continuing education for professionals is the most basic requirement for continuous professional development. The enhancement of the professionalism of librarians will also be possible through the establishment of a systematic continuing education strategy of the national level. In this study, we tried to derive a strategy for continuing education for librarians in Korea by analyzing the internal and external environment of national institutions that are the center of continuing education for librarians. To this end, we proposed a complex framework of PEST-3Cs-SWOT as a systematic environmental analysis methodology and tried to apply it. For PEST analysis, literature related to library, librarian, and librarian education was extensively reviewed, and for 3Cs analysis, in-depth interviews with internal employees, questionnaire data analysis on the demand survey of training subjects, and case studies of similar institutions in Korea and abroad were conducted. Based on this, SWOT analysis was conducted, and finally, 4 strengths-opportunity strategic tasks, 5 weaknesses-opportunity strategic tasks, 5 strength-threat strategic tasks, and 3 weaknesses-threat strategic tasks were derived. This study will be meaningful in that it presents strategic tasks for continuing education institutions in Korea, and at the same time suggests and applies a complex analysis methodology that can be applied to tasks similar to development plans and strategy establishment.
