최근 생활수준의 향상과 정보통신산업의 급속한 발전으로 인하여, 정보통신 기기 및 정밀제어 기기의 보급증가로 전압품질에 관한 관심이 높아져가고 있다. 특히, 전압품질에 민감한 수용가(산업체, 공장, 상가, 정보산업관련빌딩 등)의 전기피해 보상 요구 등이 증가되고 있는 추세이다. 특히, 21세기는 정보화 사회가 본격적으로 진전되기 때문에 전압품질에 대한 일반수용가의 반응은 상당히 민감하다. 따라서, 정부의 대체에너지 개발사업의 성공적인 결과에 힘입어, 이제 바야흐로 대체에너지전원이 보급 및 확대가 이루어져야 할 현재의 시점에 있어서, 일정 수준의 전압품질을 유지하면서, 개발된 대체 에너지전원을 기존의 배전계통에 도입 보급해 나아갈 수 있는 기술의 개발은 상당히 중요하다고 할 수 있다. 분산형전원이 도입된 배전계통은 기존의 부하만이 존재하는 배전계통과는 달리, 부하와 전원이 혼재되어 운용되는 형태로 되기 때문에 분산전원의 연계에 따라 발생이 예상되는 문제점을 검토, 분석할 수 있는 분산전원 배전계통연계용 해석 프로그램이 요구되고 있다. 따라서 본 논문에서는 분산전원이 배전계통에 연계되어 운용되는 경우, 사고시에 발생할 수 있는 현상을 분석하는 해석 알고리즘을 제시하였다.

The purpose of this study is to explore the research trend changes of convergence education since 2011 compared to the convergence education research that has been steadily continuing in science education. The trend in convergence education were investigated by comparing the number of publications, research subjects, research content, and topic linkages with previous studies, and using the network analysis method to check recent research trends. In the field of science education, the number of papers related to convergence education has been published more than 8.0% steadily, and it has been increasing since 2012, then decreasing again from 2015 and gradually increasing again from 2017. The subjects of study were high in elementary school students, while those in middle school, high school, and university students were low. While the number of in-service teachers increased, the number of pre-service teachers decreased, and the literature and public increased somewhat. In study content, effectiveness studies decreased, while development studies increased, and theoretical and perception studies appeared similar. In thematic linkage, the intra-science linkage was 23.9%, and the extra-science linkage was 76.1% and engineering/technology and art were high in extra-science linkage. In network analysis, elementary, science, STEAM, and program words have a high frequency of appearance and appear together with other words to lead the network. The educational implications of the research trend of convergence education will be more emphasized in the field of science education in the future, and in order to take root in the education field, research on secondary students should be more actively studied. In addition, it is necessary to move away from research on STEAM-centered program development and effects, and to increase research to establish the philosophical basis and theoretical of convergence education.

The purpose of this study is to investigate effects of 1 or 2 years old infant to target infant care facilities and the sense of family activities conducted in conjunction with the infant's physical development and infant-parent interaction. The purpose of this study, research questions are as follows. First, child care center-family linked sensory activity is effective in the infant's physical development? Second, child care center-family linked sensory activity is effective in the infant-parent interaction? The subjects of this study are 56 infants of 1-2 year old and their mother or father 56 people in S and D infant care facilities in K city. S infant care center, experimental group, carry out child care center-family linked sensory activity. D infant care center is control group to apply an integrated program. The child care center-family linked sensory activity are conduct on 24 times, 3 times a week, totally 8 weeks. The results were as follows. First, child care center-family linked sensory activities are partially effective on the infant's physical development than the control group. Therefore, in order to promote the development of the infant's physical development, home and child care center will be done in conjunction with sensory activities are needed. Second, child care center-family linked sensory activities had positive effect on infant-parent interaction than the control group. Therefore, to improve infant-parent interaction, it is necessary to carry out child care center-family linked sensory activities. In conclusion, child care center-family linked sensory activities are correlated in positive effects on the physical development of infants and the infant-parent interaction.

The purpose of this study was to identify the difference of creativity according to the type of brain dominance for deveoping pre-service early childhood teachers's creativity teacher education program. The subjects of this study were 210 pre-service early childhood teachers. The tests were conducted by using the Herrmann' BDI and TTCT: verbal. The study have applied Pearson product-moment correlation to find out relation between the type of brain dominance and creativity, and used multi-variate analysis to find out the difference of creativity according to the type of brain dominance. The results of the study are as follow; first, the upper left brain, lower left limb, and right brains had no relation to fluency, flexibility, originality and overall linguistic creativity. The lower right limb showed a positive correlation with fluency, flexibility, originality, and overall linguistic creativity. Second, the lower left, upper right lower, and lower right limb dominant teachers showed higher fluency, flexibility, originality and overall linguistic creativity than upper left neural dominant teachers. The result of analyzing the language creativity according to the type of brain dominance of the pre-service early childhood teachers will be used as a suggestion to develop the brain-based creativity teacher education program.

It is the basic direction of revised education course to bring up the autonomous and creative Koreans to lead the 21st century. In the music education of the middle school it could be said that music program using computer is a very effective medium for learners' sake of stimulating their audio-visual sense at the same time. In this study, I will look around the facility of the computer music program and tried to find the application method to connect the creative learning activity in music class. And I will also show the application method in the musical activity area. For this, I proposed the method for students' creative learning activity in the middle of using Finale 2010 for music notation, Window Moviemaker for image editing and Goldwave for sound editing.

In information and communications society, the numbers of elementary students who violate copyright law have been growing due to lack of understanding so they are needed to be educated on copyright. However, current education only has focused on copyright infringement, few numbers of educations have instructed copyright oriented examples linked to regular curriculum. Therefore, the purpose of this study is to grow elementary students's understanding of copyright and find new ways of education through designed copyright education program oriented regular curriculum.

The purpose of this study was to identify services and programs that will be needed for helping senior residents to be aging healthfully and comfortably in the university-based retirement community (UBRC). This study conducted a questionnaire survey targeting about 900 faculty and staff members in one of national universities. A total of 214 valid responses were analyzed for identifying necessary services and programs. The study also analyzed the differences in resident's opinions depending on their intention to live in the UBRC. Over 65% of the respondents were willing to live in the UBRC. The most desirable services were healthcare services including emergency care and nursing care and cleaning and laundry services. Regarding the educational and recreational programs, future residents chose physical exercises such as swimming and tennis and music activities such as playing instruments and singing as the most interesting programs they want to experience in UBRC. Most of the respondents were interested in mentoring college students or international students who come to the university for their degrees. The findings from the study should provide a guideline when offering services, programs, and activities in the future UBRC in Korea.
