Around 2nd century B. C. two varieties of apple, i. e. 'Nay' and 'Imgum' were already grown in China. It can be suspected that 'Nay' came from the West because of its popular word 'Pyn Por' and 'Imgum' was originated from North East Asia because of its word 'Lii Kiem'. After this time 'Imgum' was called as its popular name 'Sha Guoo' in about 15 th century. In 17th century a new variety of 'Nay' was named as 'Pyng Guoo' and this name was replaced with 'Nay' when the variety was widely supplied. In 19th century a better variety of 'Nay' was developed in the West and it was introduced into China in 20th century which was called 'Western Pyng Guoo'. As a result there were two kinds of 'Pyng Guoo', i. e. 'Chinese Pyng Guoo' and 'Western Pyng Guoo'. However, the 'Western Pyng Guoo' was more supplied and it was said 'Pyng Guoo' which was written as 'Pyng Guoo(?果)' or 'Pyng Guoo (平果)'. At present time apples were classified into 'Sha Guoo' and 'Pyng Guoo'. The old 'Nay' is now called 'Bin Tzyy' which is hardly found. From this study it is suspected that the history of Chinese apples were affected much on our introduction history and its naming.

Since at least the late 12th century, medical herbs grown naturally or cultivated in Korea have been referred to as 'HyangYak'(鄕藥, $Xi\bar{a}ngY\grave{a}o$). Herbs from other countries are referred to as 'DangYak'(唐藥, $D\bar{a}ngY\grave{a}o$). Some senior historians claim medicines made solely from HyangYak are purely Korean, since they originated and were developed fully within Korea. However, these localized medicines became abundant as the result of exchanges between Korea and other countries. Originally published in 1433, 'HyangYakJipSungBang' is the authoritative result of earlier writings of medical books using HyangYak. Comprised of a total of 85 volumes, it was large in scale and divided into three main sections: 1) a detailed description of the 703 kinds of HyangYak, 2) explanations of the 10,706 different herbal formulae and 959 types of symptoms or diseases, and 3) descriptions of the 1,416 various acupuncture and moxibustion formulae. It's noted that 'HyangYakJipSungBang' was not written all at once. In the process of its writing, the number of formulae increased through medical exchanges between Korea and China during the 15th century.

As a result of reviewing various documents and existing researches, since the late Goryeo period, the most active period in the Ondol(溫突, Korean floor heating system) facilities is the 17th century. The phenomenological reason was recovering the buildings destroyed by the Japanese Invasion of Korea in 1592(壬辰倭亂) & the Manchu War of 1636(丙子胡亂), but the underlying cause was an abnormal climate in which a pair of summer and winter cold continued. In the 17th century, as the Ondol facilities grew rapidly without distinction between regions and classes, the supply and demand of fuel caused economic and natural environmental problems. And a negative and positive view on Ondol was suggested. Since the middle of the 18th century, when the demand and supply of Ondol reached its peak, which could no longer increase, a new awareness of Ondol began to grow. The room was called the Panbang(板房) and the Ondol, depending on the material that made up the floor. It was considered natural to have the Ondol from this time on. The Incan(因間) and Jo(竈) that were made to burn were started to be recorded as a kitchen, regardless of size and function. Changes in social awareness of Ondol have led to concerns about heating efficiency. A variety of architectural explorations were conducted. Such a search was later realized in concrete architectural form. There is a double Ondoll structure, and the column spacing is reduced compared to the previous one. The heat buffer space is formed around the Ondol room, and the double window can control the light and the air going in and out.

Through this paper, all the provisions of the enforcement statutes stipulated in the Joseon's law code were investigated and major medical issues and interests in the Joseon Dynasty were analyzed. The characteristics of each period reviewed in the text are as follows. The early Joseon Dynasty is divided into three periods. First of all, Joseon filled the gap in the law with the active acceptance of the Ming Dynasty's law code, Daemyeongrul, which conformed to Confucian virtue. Next, the completion of Gyeonggukdaejeon was an opportunity to prepare the basis for Joseon's medical laws. Lastly, from the late 15th century to the 16th century, the existing medicine promotion measures and emphasis on hyangyak(domestic herb) continued. it can be said that Joseon's politicians needed a medical policy based on Confucian virtues and maintained state-led promotion policies, but on the other hand, there was no other alternative to try newly by reflecting the limitations and failures of the policy. The late Joseon Dynasty is also divided into three periods. First of all, the period from the late 16th century to the early 18th century was marked by the growth of families in technical positions. The era of King Yeongjo can be said to be the period of reorganization of medical related laws. Finally, the period after the late 18th century is a period of passive regulation and supplementation. Lastly, the revision of the actual medical law was not made or reflected in era of King Jeongjo. In the case of the early Joseon Dynasty, the policy shifted from state-led to families in technical positions. However, in the 19th century, the weakening of the royal authority led to the weakening of the overall administrative system of the country, and the pharmaceutical policy had to be limited.

The first part of this thesis gives some brief explanation of the theory and history of imaginary elements in analytic geometry in the 19th century. The second part of this thesis discusses the theory of imaginary elements of synthetic geometry in the first half of the 19th century. Then the next part mentions the theory of imaginary elements of geometry in the second half of that same century. Particularly Christian von Staudt's and Felix Klein's theories are handled in this part. Von Staudt, who has completed the system of the synthetic projective geometry, used ‘involution’ in order to introduce a new concept ‘imaginary elements’- imaginary points, imaginary lines and imaginary plane-in synthetic geometry. Klein applied von Staudt's theory as he convey the result of the research in algebraic geometry in a picture. Von Staudt's and Klein's research may be regarded as the top of the effort to investigate possible relationship between real and imaginary structures.

This study aims to present findings of historical design trends of men's fashion, and the characteristics of changes in the types of overcoats and mid jackets shown in French pattern books of the 19th century. The primary data sources for this study comprised one pattern book, each of the17th and 18th century, and 15 pattern books of the 19th century, all of which are conserved by the French National Library. The study methods are as follows: First, analysis of men's fashion trends and the characteristics of changes by type as shown in French pattern books of the 17th to 19th centuries. Second, analysis of the evolution of type of men's overcoats and top-exterior- and-interior (outside) styles shown in French pattern books of the 19th century. As a result, a total of 69 type references were collected from French pattern books of the 17th to 19th centuries. Historically, men's fashion was largely classified into top-exterior, top-exterior-and-interior, top-interior, bottoms and accessories. The two major classifications were as follows: top-exteriors overcoats and robes, And top-exterior-and-interior as top-exterior-and-interior(outside) and top-exterior-and-interior (inside). The study also identified the forms and changes by type. Additionally, this study selected overcoats and top-exterior-and-interior(outside) which fall under typical categories to show the change in the forms of men's fashion of the 19th century. These changes in the types were designated as: continued, faded away, newly appeared and transformed. This study analyzed the time of appearance of the forms by the year of publishing in conjunction with cultural references from previous domestic and international studies. The results showed that the time of changes in the types shown in pattern books did not deviate from the mainstream, which verified their typicality.

The Diary of Muk-Jae is a historical record that describes many social aspects of the Joseon period in the 16th century. It records many scenes of its author, Lee Mun-Geon, treating patients. This paper uses The Diary of Muk-Jae to examine changes in the perception of the concept of cold damage and the text of the Shanghanlun (Treatise on Cold Damage) in the Joseon period in the 16th century. In The Diary of Muk-Jae, cold damage is understood in connection with two categories: 'dangerous disease' and 'disease caused by cold'. The Diary of Muk-Jae also presents the Shanghanlun not as a work limited to the concept of cold damage, but as a medical text that could be widely used for many different diseases. Thus, The Diary of Muk-Jae may represent a point of transition between in the perception of cold damage as seen in the Uibang Yuchui (The Collection of Medical Procedures) of the 15th century and the Donguibogam of the 17th century.
