  • That's the reason why LED lighting has to employ AC power inlet. However, LED is a kind of diode, semiconductor, it's driven by DC power. With whis reason all of LED lighting should have AC/DC converter in its systems. This converter causes energy loss, it's the target for lesson the energy loss. To reduce this energy loss, DC power distribution structure can be used. LED lighting system using LVDC is a kind of DC power distribution structure, but LVDC has severe voltage drop which makes non-uniform brightness in lighting system. In this paper, we suggest a novel structure for the uniform brightness in LVDC LED lighting system using IoT based network system. The constructed test-bed system of suggested structure shows this structure can con control the brightness with uniformity.

  • Currently, climate change is regarded as one of the most important environmental issues in the 21st century. However, climate change education is not seriously carried out in schools. This study is concerned about enhancing students' recognition about climate change and actions responding to climate change through an history discipline. More specifically, this study tried to identify the effect of history lessons on environmental education, especially focused on climate change, by performing an experiment. The experiment was designed based on Solomon four-group design and carried out in one high school in Gwangmyeong city. Findings of the experiment are as follows. First, students who had taken the reorganized history lesson based on climate change - that is, students with experimental treatments - gained higher understanding of climate change than before and students of control groups. Second, students with experimental treatments gained higher understanding about relationship between history and climate change. Third, students with experimental treatments showed higher possibility of taking responding actions to climate change. In conclusion, history lessons reorganized with environmental issues, for instance climate change, have big potential for environmental education since they contribute to enhancing environmental recognition and prompting responding actions through exploration the effects of existing historical facts. Interdisciplinary approach like that taken in this study will provide students with more comprehensive and extended prism for the environment.

  • This study concentrates on investigating teaching methods with which students of a commercial high school, located in a rural district, can improve their attitude toward mathematics. To begin with, this study examines the causes which make the students take negative views against it through a survey of their current attitude toward mathematics; offers a special class for them to develop a positive attitude toward it: and then, figure out how much they change their academic attitude within the class and how much they improve their academic achievement as well. The results can be summarized as follows: First, the experimental groups showed terribly negative attitudes toward mathematics, and their academic achievements were very low compared with students of academic high schools nearby, Second, thanks to the special class given to improve their attitude toward mathematics, the experimental groups ended up taking a meaningful positive attitude toward it and developing their academic achievements in the subject. On the other hand, the controlled groups without any chance to receive special lessons remained unchanged. Therefore, it is indicated that a special lesson, properly provided, would play an important role to improve students' positive attitude toward mathematics and develop their basic academic achievements.

  • This Study attempts to verify the effects of expository and inquiry instruction on learning attitude and academic achievement of health education in elementary school. For the accomplishment of the above purpose, specific problems were formulated as follows: The expository instruction is based on David Ausubel’s Advance Organizers and the inquiry instruction, Richard Suchman’s Inquiry Training in this study. To testify the above research problems, 247 students of six classes were randomly sampled from sixth graders of “Y” elementary school, located in Suwon city. One group was taught by expository instruction method and other group was taught by inquiry instruction method. The measurement tools used in this study were learning attitude test, pre-post academic achievement test, expository teaching-learning sheets and inquiry teaching-learning sheets. The experimental treatments had been lasted for eight weeks from June to October 1996. After the experimental treatments, to testify the effects of the experiment, the pre-test and post-test were administered and the results of the tests were compared by t-test. The conclusions were as follows; 1. There was a significant difference between expository and inquiry instruction(p〈.001). Inquiry instruction was more effective than expository instruction in changing learning attitude. 2. There was a significant difference between expository and inquiry instruction(p〈.001). expository instruction was more effective than Inquiry instruction in changing academic achievement. This study suggests that instructional method should be determined in accordance with the purpose of the lesson.

  • Purpose: The article looks at the member' rights and trustees duties and determines where should the emphasis be as it often happens that these two aspects often clash. Research Design, Data and Methodology: It is determined in this article whether the trustees owe fiduciary duties to both the fund and members and further determines whether the trustees should advance the interests of the members. Results: The article further looks at the governance of the retirement funds and argues that the proper governance of these funds protects the interest of the members. The duty to disclosure of information to members is of paramount importance to ensure that members are able to make well informed decisions. Conclusion: The article considers the issues of disclosure of information from other countries, United Kingdom, United States and Malawi. It is argued in this article that trustees must be persons who are trustworthy and have the best interest of the members at heart and must therefore familiarize themselves with the laws that regulate their duties.

  • The purpose of this study is to investigate how students' mathematical creativity changes through problem-solving instruction using problem-posing for elementary school students and to explore instructional methods to improve students' mathematical creativity in school curriculum. In this study, nonequivalent control group design was adopted, and the followings are main results. First, problem-solving lessons with problem-posing had a significant effect on students' mathematical creativity, and all three factors of mathematical creativity(fluency, flexibility, originality) were also significant. Second, the lessons showed meaningful results for all upper, middle, and lower groups of pupils according to the level of mathematical creativity. When analyzing the effects of sub-factors of mathematical creativity, there was no significant effect on fluency in the upper and middle groups. Based on the results, we suggest followings: First, there is a need for a systematic guidance plan that combines problem-solving and problem-posing, Second, a long-term lesson plan to help students cultivate novel mathematical problem-solving ability through insights. Third, research on teaching and learning methods that can improve mathematical creativity even for students with relatively high mathematical creativity is necessary. Lastly, various student-centered activities in math classes are important to enhance creativity.
