The main purpose of this study is to analyze the educational effectiveness of historical thinking contents through the experimentation methodology. The procedures of this study will review foreign and domestic historical thinking cases of archival contents for history education; derive some implications from the review; and apply the implications to classes targeted for first year high school students. It can be said that classes utilizing historical thinking contents have beneficial effects on the subcategories of historical thinking, that is, chronology comprehension ability, historical inquiry ability, historical imagination, and historical judgment ability. The average between before and after examination results shows a statistically meaningful difference. In addition, this study shows that students obtain better scores after examination than before.

This study aims to provide suggestions for the development of educational contents on historical events that can solve the existing curriculum's problems, such as the disproportionate weight given to Western historical events. The study focuses on content ranging from the start of the Agricultural Revolution (7000 BC.) to the start of the Industrial Revolution (AD. 1760). The results are as follows. We used the Delphi technique for deriving global historical events. Among them, 56 historical events were selected as the data for Social Network Analysis (SNA). The results of SNA showed that topics related to Civilization has a high priority. In addition, the results of a coagulation analysis showed the events can be divided into seven groups. The classification criteria is different from the criteria used for the current period. We expect that the suggested framework developed for historical contents will constitute a new approach to historical interpretation through network visualization and linkage analysis.

Since wireless Internet services and small mobile communication devices come into wide use as well as the use of GPS is rapidly growing, researches on moving object, whose location information shifts sequently in accordance with time interval, are being carried out actively. Especially, the researches on vehicle moving object are applied to Advanced traveler information system, vehicle tracking system, and distribution transport system. These systems are very useful in searching previous positions, predicted future positions, the optimum course, and the shortest course of a vehicle by managing historical data of the vehicle movement. In addition, vehicle historical data are used for distribution transport plan and vehicle allocation. Vehicle historical data are stored at regular intervals, which can have a pattern. For example, a vehicle going repeatedly around a specific section follows a route very similar to another. If historical data of the vehicle with a repeated route course are stored at regular intervals, many redundant data occur, which result in much waste of storage. Therefore this thesis suggest a vehicle historical data store scheme for vehicles with a repeated route course using similar trajectory which efficiently store vehicle historical data.

Most damaging earthquakes come as complex sequences characterized by strong aftershocks, sometimes by foreshocks and often by multiple mainshocks. Complex earthquake sequences have enormous seismic hazard, engineering and societal implications as their impact on buildings and infrastructures may be much more severe at the end of the sequence than just after the mainshock. In this paper we examine whether historical sources can help characterizing the rare earthquake sequences of pre-instrumental times in full, including fore-, main- and aftershocks. Thanks to the its huge documentary heritage, Italy relies on one of the richest parametric earthquake catalogues worldwide. Unfortunately most current methods for assessing seismic hazard require that earthquake catalogues be declustered by removing all shocks that bear some dependency with those identified as mainshocks. We maintain that this requirement has led most modern historical seismologists to focus mainly on mainshocks rather than also on the fore- and aftershocks. To shed light onto major earthquake sequences of the past, rather than onto individual mainshocks, we investigated 10 damaging earthquake sequences ($M_w$ 4.7-7.0) that hit the L'Aquila area and central Abruzzo from the 14th to the 20th century. We find that most of the results of historical research are important for modern seismology, yet their rendering by the current parametric catalogues causes most information to be lost or not easily transferred to the potential users. For this reason we advocate a change in current strategies and the creation of a more flexible standard for storing and using all the information made available by historical seismology.

Postmodern designers freely used historical motifs as symbolic expressions or ornamentations. Historical references often became a key to express their ideal against modern standardization. Among the historical references, Art Deco style was frequently appreciated by postmodern furniture designers from the 1960s throughout postmodern era. This study is Intended to explore the way of incorporating Art Deco in postmodern furniture design. Rational Italian designers in Anti-design Movement began to adapt historical motifs and Pop, and this spread out throughout to other Postmodern designers. The research explored how Art Deco and postmodern design are related and what the examples of Art Deco revival in the postmodern era we. In this sense the research mainly covered from the exhibition catalogs from the 1960s to 1990s. As a result of stylistic, symbolic, methodological analysis, Art Deco revival in postmodern era was an essential method to express anti-modern characteristics of postmodernism. In postmodern design, Art Deco was one of historical styles that surpass the limitation o( modernism, at the same time decorative style that express the postmodern ideal.

Classification of archival collections in China is usually divided into two approaches, arrangement classification and retrieval classification. Focusing on arrangement of archives, this paper reviews what is the content and principle of arrangement, and how these principles are applied to actual arrangement of records and archives in China. The review examines the historical archives of Rep. of China, in the Second Historical Archives of China. It is expected that current review could enlighten studies on arrangement of historical archives created by Government-General of Chosun.

In this paper, I suggest several techniques to estimate covariance matrix and compare the performance of the global minimum variance portfolio (GMVP) in terms of out of sample mean standard deviation and return. As a result, the return differences among the GMVPs are insignificant. The mean standard deviation of the GMVP using historical covariance is sensitive to the estimation window and the number of assets in the portfolio. Among the model covariance, the GMVP using constant systematic risk ratio model or using short sale restriction shows the best performance. The performance difference between the GMVPs using historical covariance and model covariance becomes insignificant as the historical covariance is estimated with longer estimation window. Lastly, the implied volatilities from ELW prices do not lead to superior performance to the historical variance.

So far, the Japanese exhibitions in the colonized Korea, especially the Joseon Industrial Exhibition of 1915, haven't been studied sufficiently; they have been understood mainly as political propaganda to legitimize the Japanese colonization of the Korean peninsula; many scholars have agreed that Japan highlighted material developments in Korea under the benevolent guidance of Japan by displaying strong visual contrasts between the modern and the traditional. So, they only acknowledge colonial modernity; this perspective regards Western forms as the sole expression of architectural modernity, not only in the exhibition but also in the colonial space and time. However, to be on a par with the West, Japan started to develop a series of historical narratives in searching for its historical origins in Asia, and it also carried out archaeological investigations in the Korean peninsula around the early 1900s. I argue that the developed historical narratives with traditional Korean artworks and architecture (i.e. the shared historical origins between Japan and Korea) influence the architectural conditions of the 1915 exhibition. And, the status of traditional Korean architecture in the Japanese exhibition expresses architectural modernity in terms of showing historical progress.

The concept of style provides a useful structure in history of Art. In aspect of formative art, dress and art work are alike, so style is a useful concept in the historical methodology on dress. The main purpose of this study was to apply the art criticism to the historical methodology on dress. For this purpose, documentary studies about style as a tool of historical research were proceeded. The results were as follows : 1. The concept of style consists of the external form and the internal meaning as double roots. Therefore, it's indispensable that the two asp-ects of style, form and meaning, must to be harmonized to describe the historical phenomena in dress. 2. The change pattern of style in dress is not always predeterminate and regular according to the cyclical theory. From the alternative point of view, the change pattern of style could be to describe the continuous theory proposed by kroeber, Brodsky. The whole change of style is considered "liked solution" by this theory.is theory.

Cost estimate system Will be changed from the prime. cost calculation to the historical cost data because the present system has some problems. In this situation, each owner should prepare his own cost estimate system based on the historical cost data. In this study, the standard work items were classified and the criteria of their work amount computation were established for rural improvement projects. And also the historical cost data were collected in all range of rural improvement projects, and the database system, "HICOMS" (HIstorical COst data Management System) was built. In order to test the applicability of the HICOMS, standard work cost and contractor cost were compared. The results by HICOMS showed high significance and it was concluded that the HICOMS could be applicable for the cost estimate of the rural improvement projects. projects.
