In this research, a questionnaire was developed to investigate high school students' viewpoints, originating from science history, on 'motion of on object', the subjects were seventy- five 10th grade students and sixty-five 11th grade students. Results found that the highest percentage among the types of 10th grade students' thoughts was related to the Middle Ages 'Impetus' viewpoints. Percentages of 11th grade students' thoughts were highest for Middle Ages and Newton views. These results provided proof that the development of student thoughts' based on science history' are consistent with school year. Furthermore, student thought regarding 'object motion' under the conditions of no force, vacuum, or air under a weightless stage were related to progressive viewpoints on science history. However, the percentage of thoughts related to earlier viewpoints were considerable. Student thoughts on parabolic motion, circle motion, and conservation amount of motion were found to be highly significant in similarity to the viewpoints of Galilei, Descartes, and Huygens; view cultivated before Newton. Consequently, this study determined that educational efficiency could be raised by providing historically more progressive views to cope with conflictory student thoughts-thoughts related to past views in science history.

Makkah Al-Mukarramah is the capital of Islamic world. It receives special attention from the Saudi government's rulers to transform it into a smart city for the benefit of millions of pilgrims. One of the 2030 vision objectives is to transform specific cities to smart ones with advanced technological facilitation, Makkah is one of these cities. The history of Makkah is not well known for some Muslims. As a result, we built the concepts of our application "Ain Makkah" to enable visitors of Makkah to know the history of Makkah by using technology. In particular "Ain Makkah" uses Augmented Reality to view the history of Al-Kaaba. A 3D model will overlay Al-Kaaba to show it in the last years. Our project will use Augmented Reality to build a 3D model to overlay Al-Kaaba. Future work will expand the number of historical landmarks of Makkah.

The purpose of this study was to develop 'Science History Based Chemist Inquiry Program' for the science-gifted in high school and investigated the application effects on the understanding toward the nature of science, scientific attitudes, and science career orientation. This study was conducted with one class of 17 scientifically gifted high school students, and the 'Science History Based Chemist Inquiry Program' was applied during 22 class hours. The results of this study were as follows: First, the science gifted students' understanding toward the nature of science showed a statistically significant improvement (approximate significance probability .005). Property of the scientific model, sub-domain of the nature of science, is significantly improved (approximate significance probability .029). This result show that 'Science History Based Chemist Inquiry Program' can improve the scientifically gifted high school students' perception about nature of science. Second, the scientifically gifted students' scientific attitude wasn't changed significantly. However, the openness and creativity in the sub-domains of the scientific attitude showed a statistically significant improvement (p<.05). Third, science career orientation of science-gifted did not show a statistically significant change. But the value of the level of awareness about the science career has been significantly improved (p<.05).

This study aims at reviewing the research trends of records and archives management history published during the past 12 years, analyzing issues, and suggesting future tasks in related research areas. It starts with categorizing research areas of records and archives management history in archival sciences. All 31 articles have been selected from the 2 journals on archival science and 6 journals on related research areas. In quantitative measurement, the paper draws up 31 kinds of article bibliographies and looks at the current status of subject areas by year and author. In content analysis, selected articles are categorized into 3 subject areas, that is, general history, domestic history, and foreign history. For each subject area, research trends of the historical and regional studies are analyzed. This study concludes with emphasis on a new research direction between practice and points out that academic theory should be required for the future development in records and archives management history.

To investigate the impacts of transgenic rice on freshwater organisms, we conducted two life table experiments using Daphnia magna for fifteen and twenty days, respectively. We examined life history traits such as population growth rates (r), reproductive rates ($R_0$), generation times, and survivorship. In the first experiment, we used non-drought-stressed transgenic and non-transgenic rice harvested in 2005. In the second study, we used non-transgenic and transgenic rice harvested in 2006 following drought stress. Each experiment involved three treatments in which D. magna neonates were fed with Selenastrum capricornutum (control treatment) and S. capricornutum with 5% aqueous extracts of non-transgenic rice (N-T) and transgenic rice (T). In the first experiment, D. magna showed reduced population growth rates and lowered fecundity in the N-T and T treatments. In the second experiment, D. magna receiving both transgenic and non-transgenic rice extracts showed very high mortality, low population growth rates and reproduction rates. We could not detect any significant negative effects of extracts from transgenic rice on D. magna life history traits at 95%.

Cho Heon Yeong's 'Tongsokanuihagwollon' is an introductory and essential book on Traditional Korean Medicine(TKM), and now we can nearly take it as classic. It contains almost whole contents of TKM : physiology, pathology, herbology, meridian & acupoint, internal medicine, diagnostics, formula science, etc. He wanted to help people get TKM services easily on their own through this book. In the first chapter following the introduction, he inserted Yin-Yang theory, and his lecture on Yin-Yang theory continues for 88 pages, taking 17% of the whole book. Yin-Yang theory chapter is composed of 14 parts which tells about concept, definition and meaning of Yin-Yang, change of Yin-Yang according to time, season, constitution, body region, meridian, herb, etc. Last part refers to disharmony & dysfunction of Yin-Yang in body, so he showed both theoretical and clinical view of Yin-Yang theory. He wrote some quotations from the book 'Complete Works of Jingyue(景岳全書)', 'Huangdi's Internal Classic(黃帝內徑)', 'Introduction to Medicine(醫學入門)', etc. He tried to explain easily about Yin-Yang theory with modern but rough language of science. He seemed to already know clearly that without modern science TKM cannot progress and will soon be overwhelmed by western medicine, and acted his own way to spread spirit of TKM in the period of rapid change & conflict between two civilizations.

We reconstruct the expansion history of the universe using type Ia supernovae (SN Ia) in a manner independent of any cosmological model assumptions. To do so, we implement a nonparametric iterative smoothing method on the Joint Light-curve Analysis (JLA) data while exploring the SN Ia light-curve hyperparameter space by Markov Chain Monte Carlo (MCMC) sampling. We test to see how the posteriors of these hyperparameters depend on cosmology, whether using different dark energy models or reconstructions shift these posteriors. Our constraints on the SN Ia light-curve hyperparameters from our model-independent analysis are very consistent with the constraints from using different parameterizations of the equation of state of dark energy, namely the flat ΛCDM cosmology, the Chevallier-Polarski-Linder model, and the Phenomenologically Emergent Dark Energy (PEDE) model. This implies that the distance moduli constructed from the JLA data are mostly independent of the cosmological models. We also studied that the possibility the light-curve parameters evolve with redshift and our results show consistency with no evolution. The reconstructed expansion history of the universe and dark energy properties also seem to be in good agreement with the expectations of the standard ΛCDM model. However, our results also indicate that the data still allow for considerable flexibility in the expansion history of the universe. This work is published in ApJ.

The aim of this paper is to analyze the trend of the research product of Korea and Japan about each other in 20th century. The author analyzed the published year, main period, and author of the research product of history. So she explored the resent state, size, history, and gap of the research product between Korea and Japan. The study about Japan history in Korea began after 1945. However, the study about Korean history in Japan began after 1875. So the study about Japan history in Korea is falling behind Japan for 70 years. As a result, research including the amount of research the number of researchers, the diversity of the minor subject is 1/3 of that conducted by Japanese Scholars.

This paper explores the conditions and potential of newly designed and tried methodology of big data analysis that apply to Korean history subject matter. In order to advance them, we need to pay more attention to quantitative analysis methodologies over pre-existing qualitative analysis. To obtain our new challenge, I propose 'digital history' methods along with associated disciplines such as linguistics and computer science, data science and statistics, and visualization techniques. As one example, I apply interdisciplinary convergence approaches to the principle and mechanism of elite reproduction during the Korean medieval age. I propose how to compensate for a lack of historical material by applying a semi-supervised learning method, how to create a database that utilizes text-mining techniques, how to analyze quantitative data with statistical methods, and how to indicate analytical outcomes with intuitive visualization.
