Infinity is very important concept in mathematics. In history of mathematics, potential infinity concept conflicts with actual infinity concept for a long time. It is reason that actual infinity concept causes difficulty in our perceptions. This phenomenon is called epistemological obstacle by Brousseau. So, in this paper, we examine the infinity in terms of mathematical didactics. First, we examine the history of development of infinity and reveal the similarity between the history of debate about infinity and episternological obstacle of students. Next, we investigate obstacle of students about infinity and the contents of curriculum which treat the infinity Finally, we suggest the methods for overcoming obstacle in learning of infinity concept.

The storehouse for ice was an installation to use the ice during summer season. Even though it shows various versions of styles according to the different periods and regions, it consistently developed through the history with structural characteristics. In this study, first, the management of the icehouse system through the history is examined; second, seven existing icehouses in Korea are investigated in terms of their size, material, history, structure ; and finally, the structural patterns of the ice houses are examined.

The Main concern of this thesis is on the possibility to apply Hermeneutics to architectural history, with a view point that the past architecture can be seen as a text, this study analyse the relationship between the past building and interpreter, the epistenological tool for interpretation and historian. After reviewing the characteristics of architectural history with regard to text theory, this study can lead to the conclusion that the interpretation of past architecture can be defired as dynamic dialogue which depend upon the time.

The machine structure or parts has been arrive at a fracture, depend on crack by repeated load. Machine designer is estimate of fatigue strength in early stages the design for prevent fatigue fracture, then necessary its load history. This research study is using diesel locomotive in measurement of load history for fatigue design of rolling stock. The relation between velocity and amplitude of load history was found. We confirmed that the increase of velocity make to increase the magnitude of amplitude.

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.

This study discussed on production, procedures of collection, accessibility, copyright of archival records for designing oral history archive information system, and aimed to suggest practical standards by developing guidelines for evaluation and building of web oral history archives. For this, based on evaluation framework, guidelines for evaluation designed by researchers were applied to five domestic and foreign web oral history archives as case study analysis. Base on the results of the analysis, some possible suggestions were made for building successful web oral history archive information system in Korea.

This research aims to analyze the reciprocal relation between 'history from below' and archives and to set forth the overall tides of records management in England. For the Study, the articles published in the History Workshop Journal were analyzed. They used public records and private records such as newspapers, diaries, letters and oral records. Consequently Various kinds of community archives have recently flourished in England and endeavour is being made to expand the horizon of records management by TNA. This can be assessed as a new sort of soil for the history from below.

In this study, we investigated the application of oriental history of mathematics in school mathematics teaching. We set up three study problems to achieve this purpose. First, we analyze the middle and high school mathematics textbooks and auxiliary books. Second, we survey the mathematics teacher's knowledge and degree of application on history of mathematics. Third, we develop the teaching and learning materials on oriental history of mathematics. We performed three study-methods to settle above study problem. First, we analyzed 24 textbooks and auxiliary books for study problem 1. There were 6 middle school mathematics textbooks and 6 auxiliary books and also 6 high school mathematics textbooks and 6 auxiliary books. We categorized the contents into "anecdote", "systematization", "application of problem", "expansibility of thought", and "comparative of the contents". Second, we surveyed the 78 mathematics teachers's knowledge and degree of application using questionnaire about knowledge and application on history of mathematics. The questionnaire was made up of four types of question; the effect of material about history of mathematics, the understanding of western history of mathematics, the understanding of oriental history of mathematics; the direction of development of teaching material. Third, we exemplified the teaching and learning materials about three categories: "anecdote", "comparative of the contents".

The purpose of this paper is to review and analyse the influence of Hegel on architectural historiography. With the point of view that Hegel is the origin of architectural history, this study try to find out how Hegel's philosophy and aesthetics deeply influenced the principle and method of architectural historiography. As a kind of meta-history Hegel's idealism played a important role in the interpretation of architecture and its historiography. We can call it Hegelian legacy and it gave a determinant idea in the discours of architecture, especially Modernism. With a critical view point this study tries to reveal the mythical character of the premise and hypothesis of Hegel's historicism and also reviews its positive aspects in the history of writing architectural history. Today Hegelian thinking in architectural historiography is seriously criticized and considered as a old way of writing history. But this study tries to find a possibility to recognize the contemporary architectural situation with Hegel's concept of universal history. The return of Hegel necessarily does not mean the idea of totality and universality in practice as like in Modernism, but to widen the recognition in contemporary practice and historiography.

'Commit-bug link', the link between commit history and bug reports, is used for software maintenance and defect prediction in bug tracking systems. Previous studies have shown that the links are automatically detected based on text similarity, time interval, and keyword. Existing approaches depend on the quality of commit history and could thus miss several links. In this paper, we proposed a technique to link commit and bug report using not only messages of commit history, but also the similarity of files in the commit history coupled with bug reports. The experimental results demonstrated the applicability of the suggested approach.
