In this study we analyze critically the educational studies on the history of mathematics, and the results of the questionnaires to the mathematics teachers and mathematics teacher educators and interviews with them in order to highlight the problems which ought to be settled for more efficient using the history of mathematics in the mathematics classes. We ought to deepen the understanding of the meaning of mathematical concepts and its essential viewpoints through the historical development of mathematics, going beyond the interest and motivation of learning mathematics. In this respect there are insufficient sides in the results of the educational studies in the history of mathematics and in the recognition of the mathematics teachers about using history of mathematics. And the teachings of the history of mathematics in the mathematics teachers education courses are not sufficient in that they just survey the history of mathematics, and it is the very important task to develop the historic-genetic materials in the school mathematics and study the historic-genetic approach to the mathematics texts.

This study is aimed at the improvement of the teaching mathematics via the use of the mathematical history based on the learning stages which are understanding the problem, seeking after and solving the problem, application and development, and understanding the homeworks. General questions of this study are as follows according to the purpose of this study: First, we develop materials to use the teaching and learning stages which are understanding the problem, seeking after and solving the problem, application and development, and understanding the homeworks. Second, we search the effective methods for using materials which are developed in this study. Third, we apply materials to the teaching and learning mathematics. To answer the problems, 1 class students of the 4th grade in Gwangju participated in this study. Teaching and learning which uses mathematical history based on the learning stages is performed. The following results were obtained in this research. First, the teaching and learning using materials which is related to mathematical history is effective in improvement of students' mathematical ability. Second, the teaching and learning using material which is related to mathematics history is effective in improvement of students' mathematical attitude. In special, mathematical attitude of students who are involved in learning using materials which is related to mathematical history is more positive than that of general students using traditional teaching methods. Lastly, generalization of newly developed materials should be done to get more development and upgrade.

This study was designed to analyze the results of Vaso-Aging Degree in Oriental medical examination. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 24,077 industrial workers who had received Oriental medical examination by Oriental medicine and they submitted questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by job class, drinking history and smoking history, exercising history. The percentage of Vaso-Aging Degree were measured by using SA3000P(Medicore, Seoul, Korea). We analyzed the relationship between job class, drinking history, smoking history, exercising history and Vaso-Aging Degree using ${\chi}2$-test of the SPSS Ver. 14.0. In job class, Sales personnel were apt to have a higher level of Vaso-Aging Degree than Office workers. And getting older workers are, the higher Vaso-Aging Degree becomes. Vaso-Aging Degree of the Drinker group showed a higher level than the Non-Drinker group. Vaso-Aging Degree of Smoker group were higher than the Non-smoker group. On the other hand, Vafo-Aging Degree of Non-Exerciser group were higher than the Exerciser group. They have to manage Vaso-Aging Degree closely and educate the workers to quit smoking and drinking for their health promotion. Furthermore, continuous health check up needs to be done connectedly.

For obtaining the time history nodal responses of reactor building, a lumped-mass beam model composed of two sticks for the reactor building and the reactor support structure is developed. The time history responses for the non-isolated and isolated reactor buildings are calculated under an artificial time history, generated using the seismic spectrum curve of US NRC RG1.60. The analysis results show that the horizontal accelerations of the isolated building are dramatically decreased to one-tenths of the non-isolated one, but the vertical responses are increased by about 40%.

Historian Eric J. Hobsbawm once said "the task that historians have is to analyze the meanings of the past within the context of society and to track the changes and implementation." It would not be too far of a stretch to apply Hobsbawm's quote to art historian since art history, although quite specific, is still history. In addition, Hobsbaum also asserted that, "a mold called the past continuously forms the present or at least thought to be." It is my recognition that the major westernization of the last century took place under the Japanese colonization which served as the channel to usher in western art; however, the current 20thcentury Korean art history fails to recognize that the mold of the past, namely western art in this case, has formed the modern art of the present. Based on this recognition, attention was given to what lacked in the analysis of the current 20th-century Korean art history in terms of "Informel" which was identified as the turning point towards "modern art" in the Korean art history as well as the following "experimental art." My belief is that the art history of Korea has to be reassessed from, a socio-cultural perspective as well as adopting multi-level and diachronic understanding. However, the existing Korean art, especially the one between the end of 1950s to the 1970s was based on the perspective of "severance"; thus, raising the needs for the starting point of a new perspective. It is my conviction that meta perspective on writing is most essential in order to lay a solid basis for the Korean art scene to have a productive discussion. I feel the utmost necessity to reinterpret the typified history analysis and criticism which stemmed from the trauma under the Japanese colonization. The most urgent task is to avoid academic closeness and to share the research. Painting is an individual expression of the artist, but the act of expression is not free from the cultural and societal influence to which the artist belongs.

Dog meat was begun to be edible by the Chinese, Japanese, the French, Belginan, German Philippines Vietnamese, North-Americans African-Indians Canadian-aborigines Alaskan aborigines including Kor-eans. According to the record, Korea has a long history to have eaten dog meat from the era of Sam-kug(three kingdoms BC 57∼AC 668) and so there are numerous languages proverbs, and customs re-lated to the dog meat. Over the long history there have been many records and recipes about the edib-leness of dog meat. But at present time only the way of cooking such as Bosintang(a soup) Suyuk(a boiled meat) Duruchighi(boiled meat added spice and slightly roasted) Muchim(boiled meat added by spice and mixed) Gaesoju(an extract) Jeongol(boiled meat mixed with spices vegetables and water on the pot) remains. Koreans eat dog meat following the traditional customs n the Boknal(hottest day in summer). Also the areas of Buyo. Sochon, Boryong adn Chongyang of Chungnam province and the ad-jacent areas like Kongju, Iksan, and Nonsan have customs to kill the dog and offer dog meat to the gue-sts in time of small or big occasions such as funeral ceremony Hoigap(anniversary of one's 60th birth-day) and one's birthday. This range of customs is expanding larger and larger. These areas are the cen-ter of past Baekche(BC 57∼AC 660). In spite of this it is unreasonable, and excessive action for foreig-ner to fine fault with the dog meat or Korean food culture.

In Korea, confectionery refers to biscuits, snacks, chocolate, candy and gum. The first sweet in Korea is the Yumilkwa (oil-and-honey pastry) in the Goryeo Dynasty which was mentioned in history book, and is seen to be popular in medieval Korea. Korea's confectionery industry began in 1945 with the aid of the U.S. forces, Haitai Confectionery company produced sweets. The first confectionery product is 'Yeon yang gang'. In the 1970s and 1980s, the confectionery industry developed along with economic growth in Korea, and many of the products released at this time are still loved. Now the domestic market is saturated, sales of domestic confectionery companies are decreasing due to low-priced offers made by importers. It is necessary to develop products with high quality and brand power that can lead the market, and I think it is necessary to target the undeveloped market like the Halal market.

Since the beginning of her dramatic career, Suzan-Lori Parks has considered digging up and restoring African-American history buried under the dominant white Anglo-Saxon history as her mission as a playwright. In Red Letter Plays, she attempts what Deborah Geis called "canon-critique" by taking canonical work by Nathaniel Hawthorne and casting an African-American character as the main character and describing her oppression as an African-American female. This paper argues that Suzan-Lori Parks accuses the oppressive social system by restoring and representing the history of sexual, economic, and racial exploitation that African-American females had to suffer through the dominant image of body and blood. Parks had to rewrite the history of black female characters on their bodies and in the blood because their bodies have been the ultimate object of revulsion and attraction in the perspective of white male. While abhorring and despising Hester La Negrita's abject body, male characters in In the Blood nonetheless not only exploit her sexually and economically but also impregnate her. Hester resorts to her only means of revolting against this oppressive system; she kills her most beloved son and writes "A" on the floor with his blood. Likewise, Hester Smith in Fucking A, who wears "A" on her bosom like Hester Prynne, which in this case means "abortionist," "saves" her son from the hunters by slitting his throat. Abundant graphic and sensational images written on black female body and in the blood are Parks's dramatic strategy to rewrite the forgotten and hidden history of black women's history.

This paper deals with the history of one of the well-known and historically important problems in probability, "Gambler's ruin". This problem was first solved by Pascal and Fermat and published by Huygens in 1657. It was studied and extended by many probabilists in early years and thus, it became an important problem in probability history, introducing many new concepts. We would like to introduce the problem in detail to readers and share the ideas on how new problems are developed, relating to old problems.
