수학을 배운 사람이라면 수십 년이 지나서도 기억되고 회자되는 것으로 피타고라스의 정리를 꼽을 수 있다. 그런데 역사적으로 이 정리를 중요한 위치로 자리 잡게 한 역할은 피타고라스 이전, 고대 바빌로니아 시대의 이름 모를 사람들의 노력 이었으며 이를 보여주는 흔적 중 하나가 'Plimpton 322‘라는 점토판을 들 수 있다. 본 고에서는 피타고라스의 정리를 완성하게 영감을 준 Plimpton 322의 내용을 소개하며 적혀 있는 숫자들의 해석과 함께 그 시대의 뛰어난 수학적 수준을 재조명해 보고자 한다.

위상수학은 기하학, 대수학, 해석학 등 수학의 다른 분야에 비하여 비교적 늦게 연구되기 시작하였고 Euler는 위상수학의 시조로 알려져 있다. 우리는 먼저 위상수학의 기원과 발달에 대해 살피고 Euler의 삶과 업적에 대해 알아본다.

The objectives of this study was to explore the concept, the origin and history, and classification of amenity. Amenity is a new approach about nature, environment and the world. The concept, origin and classification of amenity was widely diversified, however, the concept of amenity was inclusive and abstract, so amenity was easier to recognize than to define. Even though many people were interested in amenity, however, the movement or practice of amenity in Korea was still in infancy stage. This paper was an exploratory study of amenity and more detailed further studies on amenity should conducted in Korea. It was suggested that we should not start on philosophical question of amenity. We should rather start on practical problems of how to put into practice to insure quality of life in the community, to conserve nature, to study practical dimensions of amenity, and to develop indicators to measure amenity.

In today's man's domestic environments, the development of furnishings in their various shapes and functions is as complex as human lives. Architecture, Interior, and Furniture, each one of these have the relationship closer and closer to the direct human environments. In this study, by choosing the theme of sitting , the transformation of man's behavioral models would be examined in sociological terms. By viewing the chair as an emblematic objects made for more than just sitting, the chair has revealed the relations of man with his environment since the history of furnishings began. Qualified architects and designers know that chairs are no longer the objects, but the primary subject of furnishings. Through this examination of the emblematic typologies of periodic chairs in the history of the Western culture, in terms of their relationships with politics , religions, monarchies, societies, and etc., the meaning of the designs could be find and which could be the resolutions for the future innovative design. These refound or recreated meanings in the history of design could create another typology for the future reality.

The oriental medicine is not static knowledge. Since the publication of "Hwangjenaegyeong(黃帝內經)", it has unceasingly changed and developed, that changes and developments ate the reflex of culture and civil progression, and they also are active acceptance of the time's demand. when we look back into the history of the Oriental medicine, angle of understanding disease can be classified into two concepts ; internal-external and Eumyang. Internal-external is whether we find the source of disease internal or external. Eumyang is deciding which is more important between yin-essence and yang-gi which are components of the essence-gi of body. This thesis view course of development of theory of the oriental medicine since publication of "Hwangjenaegyeong(黃帝內經)" at certain point of internal-external and Eumyang and with those as background, will inquire into sameness and difference between the Korean medicine and the Chinese medicine, and provide an advanced course for the oriental medicine.

In this study a series of in-situ and laboratory tests such as SPT, CPT, DMT and oedometer test are performed and then the stress history of soft ground is evaluated from the different method for estimating preconsolidation pressure. Casagrande method(1936), which is generally used in the conventional design, overestimates to the known preconsolidation pressure but Becker method(1987) similarly estimates to the known values. Also the results of DMT is similar to that of Becker method, and SPT and CPT overestimates the stress history of investigated ground.

This study is to propose a curing method for a concrete wall structure under severe cold climate. The curing methods of using heated cable, heated panel and insulated form were applied. Results showed that the concrete cured by the heated cable resulted in the highest temperature history and the highest strength development at 28 days. Further, it is believed that the curing methods of the heated panel and insulated form are also recommendable for the resistance of the early frost damage on the concrete in practice.

The Nannophya species in Korea was thought to consist of only Nannophya pygmaea. Previous studies on the species, including life history and development, conservation and restoration, habitat characteristics, genetic studies, distribution, behavior, and taxonomy have been conducted. However, a new Nannophya species, Nannophya koreana, was recently discovered in Korea. Moreover, this new species was found to inhabit both Korea and Japan. Thus, the previous studies should be reevaluated in relation to the new species, Nannophya koreana, and the latter should be treated as an endangered species worldwide given the current population instability.

This Study is to analize the transfiguration of the domestic architecture in the process of modernization. Thirty two houses which were located in Taegu province and constructed during the period from 1886 to 1945, were surveyed and analized about the characteristic and their transfiguration. The modern domestic architecture of Taegu province had been constructed greatly by the missonaries and Japanes. The history of development of modern houses in Teagu province can be devided into three period in accordance with the economic policy, housing style and the method of construction. The first period (1886-1910) was the beginning of the modern house. Most of the mission houses of that period were made with brick structure of korean-western style or colonial style. In the second period (1911-1926), colonial, Japanese-western, Japanese housing style were co-exited in Teagu province. During the third period (1927-1945) new method of construction using reinforced concrete and mortar was introduced, therefore the houses become row house (a two or three-family house) and much simpler.
