Statistics was not recognized until the early 20th century as an independent science, and statistical education research came to an international milestone in the late 1940s. The purpose of this study is to investigate the historical development of statistics education research, focusing on the activities of the International Statistical Institute (ISI) and the International Association for Statistical Education (IASE). Statistics education in Korea is considered with regard to the history of international research on statistics education in this study. It implies for the direction of statistical education research to domestic mathematics education researchers and statistical researchers related to statistical education research.

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.

We investigate the history of the research of the existence of periodic solutions of a nonlinear wave equation with jumping nonlinearity, suggested by Mckenna and Lazer (cf. [15]). We also investigate the recent research of it; a relation between multiplicity of solutions and source terms of the equation when the nonlinearity -($bu^+$-$au^-$) crosses eigenvalues and the source term f is generated by eigenfuntions.

We first of all emphasize the importance of the research on the history of Korean mathematics. We next make a survey of the brief history of Chosun mathematics as a seed knowledge for further research on Korean mathematics. We hope that our survey will serve researchers as a seed knowledge of their research.

Since 1949, The first generation leader MAO zedong liked reading history books and historical biography, It led to criticism and evaluation of history and character be targeted in every movement, before the February Outline(er yue ti gang) had been revoked, the Shanghai society discussed "Hai Rui's Dismissal "basically" within the "learning and using Chairman MAO's works(huo xue huo yong mao zhu xi zhu zuo)" category, with the deterioration of the national political situation, based on the historical drama "Hai Rui's Dismissal" discussions, the dilemma of cultural propaganda and academic research appeared.

In this paper we survey on the geometric development in the history of Joseon mathematics. We have relatively many research papers on the history of equations in Joseon but the history of geometry is limited to that of trigonometry (gugosul). We survey on the results on the whole geometry including the introduction of western geometry in Joseon. Joseon mathematics developed differently during several different periods. We investigate how geometric theories developed during those periods and the meaning behind them. We do not claim that our survey is anywhere close to a complete one. This is rather a preliminary attempt to collect research results to plan our research following those of our predecessors.

This research presents author co-citation analysis of the subject area in the humanities - Korean history. Three approaches to multivariate analyses were used to display the inter-author relationships in the similarity matrix. Data on co-citation of sixty seven authors for the period of 1980­1989 were extracted from the database constructed by author. The author's name, here refers to a body of writings by a person, is the unit of analysis. The data were subjected to non-metric multidimensional scaling program create two-dimensional map of authors. Authors with similarity are clustered using hierarchical agglomerative procedure and it is found that five clusters in Korean history represent primarily research specializations. Author map of Korean history reveals the first dimension corresponding to subject orientation of authors and the second dimension corresponds to research method or research style. In factor analysis, each factor reflects research specialty made up of authors, and factor locadings demonstrate the breadth or concentration of sixty seven authors' scholarly contributions on Korean history. It is demonstrated that the· specific methodology employed by this research, author co-citation analysis, is useful to represent the intellectual structure of Korean history.

The purpose of this study is to know how to utilize foreigners such as Weltevree and Hamel who visited Korea in the pre-modern period, during history class. Both Weltevree and Hamel were Dutch men, and the first person who visited the Joseon Dynasty was Weltevree. He was a sailor of the Dutch East India Company, landed on Jeju Island in 1627, and since then, he did not return to his country. He played a major role in the execution of weapons. Hammel, the merchant catcher of the Dutch East India Company, traveled to Joseon in 1653 and contacted several kinds of people in various parts of the country for 13 years, and was able to survey the scenery and customs of Joseon. It can be difficult for students to understand the overall trends of the world history and the views of the East and the West because students learn from Western history, East Asian history, and Korean history, separately. Learning characteristics associated with East-West exchanges will enable students to understand the Western and Eastern history of the West, and understand the history of the world.

Source criticism is very important on the research of architectural history as well as general history. In this point this research studied on the original form and change of Dokrak-dang that is very important building in architectural history of Korea. The result is as in the following. Dokrak-dang that Whoijae built at first was three by two kans size that had daecheong of four kans and ondol-bang of two kans. Gye-jeong that Whoijae built was three kans size that had daecheong of two kans and ondol-bang of one kan. After Whoijae died, Dokrak-dang's ondol-bang was changed to maru between 1555 and 1556 and ondol-bang in west side and stack room was added in 1630. Gye-jeong was changed to ㄱ-shaped floor plan that was added up two kans from three kan's 'ㅡ'-shaped one.

In this paper, I will divide the history of mathematics into four development stages. These are based on significant developments of mathematical concepts or the creation of new fields of mathematics. Then, I will survey the history stages through a study of the characteristic method of research and the most important concepts from each period.
