The purpose of this study is to isolate characteristics of exhibits particularly considering educational perspectives and effectiveness in attracting the attention of visitors in famous Natural History Museums. The target exhibits were selected from the Natural History museum in London, the Australian Museum in Sydney, the American Museum of Natural History in New York, and the Smithsonian Museum in Washington D.C. A total of 107 sample exhibits used in this study from these four museums were selected as representative solid earth science education related exhibitions including fossils, geological history, and minerals. For the investigation, this study developed a checklist with seven items based on reviewing previous literature and articles pertaining to exhibit characteristics of natural history museums and science centers. Also the educational perspectives focused on classifications of exhibitions by Hein (1997). In this study, all the sample exhibit, were taken pictures of and stored on slide films for lated examination. Respectively exciting and positive results were found in all four museums. The analyses, however, indicated weaknesses as well as strengths in the four museum exhibits.

The purpose of this study was to analyze the utilization of history of science and STEAM and the elementary school teachers' perceptions about design-based STEAM instruction applying the history of science in science class. To research the utilization of the history of science and STEAM in elementary science class, educational value of design-based STEAM instruction applying the history of science, the questionnaire was revised based on research conducted by Lee & Shin(2014), Park et al.(2010), Shin & Han(2011) and developed questionnaire a total of 20 questions. It was administered to reply the questionnaire to 201 teachers of elementary school in D and G area. The results of this study were as follows: elementary school teachers did not teach actively the history of science, made it read students by simply introducing himself. They did not teach actively STEAM due to not enough time(busy to take a magnitude). They were difficult to teach, but the most focused on the 'Creative Problem-solving' process. And elementary school teachers perceived positively about the educational value of design-based STEAM instruction applying the history of science. Especially, they perceived that it can help elementary school students find a hint for solving the problem through examples of cases of scientific principles and a scientist. In conclusion, it implicates that it is need to regard elementary school teachers' perceptions on application of the history of science and STEAM, and develop specific design-based STEAM program applying the history of science in order to be applied successfully in elementary school for the STEAM settlement.

As teachings that use the ICT are more popular, many studies on the dynamic geometry environment(DGE) are under way. An important factor emphasized in the studies is to practical use learning activities of learners. In this study, we first define the learning history data in DGE. Second we develop a prototype of the DGE that is able to collect and analyze the learning history data automatically. The environment enables not only to grasp leaning history but also to create and manage new learning objects.

The purpose of this study was to explore characteristics of natural history museum exhibits from the viewpoint of science education. A total of ninety exhibits for this study were examined in national science museums of Korea and Japan. Exhibits of Tokyo national science museum were again divided into two groups: the old and traditional types, and the new and renovated ones. Even though analyzing data was not undertaken through quantitative statistical process, the interpretation of the data was valid enough to fulfill the purpose of the research. While there were clear changes and differences between the old and the new types of exhibits in Tokyo national science museum, the old part of Tokyo museum was similar to one in Korea. Based on analyzing the new types of Tokyo museum, the current movement in the field of natural history museums of Korea explicitly has toward utilizing more science education concepts and ideas.

With the discovery of metabolic mechanisms of alcohol fermentation and acetic acid fermentation in the 1800s and 1900s, the history of traditional vinegar became a turning point for changing to the history of science and technology. Since then, innovation in vinegar production has occurred, and the era of full-scale mass industrialization has opened. The most modern method, submerged fermentation, has improved the vinegar production process to produce much higher quality vinegar and provide vinegar with high productivity and quality uniformity. Innovative research for vinegar production is underway as various approaches have been developed to increase fermentation efficiency, reduce costs, and shorten fermentation time due to the trend of combining existing technologies and advanced technologies. Now that the development of the vinegar industry is currently focused on vinegar engineering, multidisciplinary approaches in various fields such as microbiology, chemistry, food technology, process engineering, and molecular biology are needed.

We use iterative smoothing reconstruction method along with exploring in the parameter space of the light curves of the JLA supernova compilation (Joint Light-curve Analysis) to simultaneously reconstruct the expansion history of the universe as well as putting constrains on the light curve parameters without assuming any cosmological model. Our constraints on the light curve parameters of the JLA from our model-independent analysis seems to be closely in agreement with results assuming ΛCDM cosmology or using Chevallier-Polarski-Linder (CPL) parametrization for the equation of state of dark energy. This implies that there is no hidden significant feature in the data that could be neglected by cosmology model assumption. The reconstructed expansion history of the universe and properties of dark energy seems to be in good agreement with expectations of the standard ΛCDM model. Our results also indicate that the data allows a considerable flexibility for expansion history of the universe.

Extremely metal-poor (EMP; [Fe/H] < -3.0) stars are thought to be genuine second-generation of stars because they were born from relatively pristine gas chemically enriched by one or two supernovae. So, the EMP stars presumably originated from outside the Milky Way (MW) are important tracers for the early chemical evolution and assembly history of the MW. In this study, we present the preliminary results on the early assembly history of the MW inferred by associating the dynamical properties of our EMP stars with those of known substructures in the MW. We also explore the star formation history of the progenitor galaxies of our EMP stars by investigating the elemental abundances of the EMP stars associated with the substructure.

The purpose of the study is to construct a History Ontology Model for historical person to analyse issues of Korean History Thesaurus and interview history specialists who are use information systems in National Institute of Korean History. This study verifies the difference between both descriptions through comparative analysis of term concept in Korean History Thesaurus and mind-map written by history major. Based on this, we build history ontology model to meet users' information needs and adapt to information retrieval system. First, to organize unique features of history, we define class and attribute and then enlisted considerations for instance input. The study suggests a possibility of new service through combination multiple features using concept extension that is a strength of ontology.

This study is to investigate archival use behavior of history teachers in high schools. The study conducted 3 times interviews with high school history teachers and carried out a survey on recognition of archives, archival use, archival seeking behavior, and harrier factors for archival use to 30 teachers from the 2 local communities of history teachers. According to the survey, history teachers have used archives for raising the historical understanding by students in their classes. But the tight curriculums of history and the lack of time to search archives were barrier factors for teachers to use archives in their classes. The teachers who participated in this survey suggested that integrated DBs of archives in Korea and source books with commentaries need to promote use of archives in history classes.
