기계역학은 자연과학에 속하는 역학을 아버지로, 기계와 이를 탄생시킨 실제적기술(technical arts)을 어머니로 하는 두 가지의 계보를 갖는다. 극히 최근까지 과학과 기술은 전혀 별개로, 다른 계층에 의해 담당되어 왔다. 약 100수십년 전까지는 과학은 기술에 힘입은 부분이 많았다. 이들이 합쳐진 것은 겨우 19세기 초, 그리고 기계역학이 학문으로서 형태를 갖춘 것은 19세기 후반부 터이다. 동역학을 포함한 기계역학의 형성과 발전의 흐름은 시대적으로 다음의 3단계로 크게 분류된다. (1) 제1기 : 자연학의 시대(~5세기) (2) 제2기 : 역학=자연철학의 시대(16~18세기) 역학의 탄생(16세기)$\rightarrow$역학원리의 형성 (17세기)$\rightarrow$역학원리의 전개와 완성(18세기) (3) 기계역학=공학의 시대(19세기~) 공학의 탄생 (19세기 전반)$\rightarrow$체계화의 시대(19세기후반)$\rightarrow$ 방법의 시대(20세기)

전통철학 연구서가 20세기 한국철학에 있어 배타적 독점권을 행사하는 데는 무리가 있다. 20세기 한국철학은 결코 학문의 무덤을 뒤지고 해석하는 데만 있는 게 아니라, 20세기 한국의 현실을 딛고 서서 철학하는 데 있기 때문이다.

This study investigated the representation and algorithms of western mathematics reflected on the algebra domains of Chosun-Sanhak in the 18th century. I also analyzed the co-occurrences and replacement phenomenon between western algorithms and traditional algorithms. For this purpose, I analyzed nine Chosun mathematics books in the 18th century, including Gusuryak and Gosasibijip. The results of this study are as follows. First, I identified the process of changing to a calculation by writing of western mathematics, from traditional four arithmetical operations using Sandae and the formalized explanation for the proportional concept and proportional expression. Second, I observed the gradual formalization of mathematical representation of the solution for a simultaneous linear equation. Lastly, I identified the change of the solution for square root from traditional Gaebangsul and Jeungseunggaebangbeop to a calculation by the writing of western mathematics.

The eighteenth century in Great Britain was the period of transformation, Great Britain externally experienced several wars intermittently mid internally transformed into the industrial country in the course of the 18th century. British shipowners were faced with short of seamen mainly due to several wars and expansion of shipping tonnage British shipowners tried to solve the mooing problem by decreasing the number of seamen from 22-23 sailors per ship of 100 tonnage in 1710's to 5 in 1810 and increasing seamen's wage from shillings per common seaman per month in the 17th century to 25 shillings in the middle of the 18th century and equation omitted during the French Revolutionary and Napoleonic Wars. What caused and resulted by specialized shipowners to cope with changeable market situation with flexibility was decrease of the number of seamen per ship and increase of wage.

멀티미디어시대 서점가 베스트셀러 판매대에 19세기에 씌어진 고전소설이 등장하기 시작했다. 나다니엘호돈의 "일곱박공의 집"을 비롯한 일련의 책들은 대부분 당대의 문학사에 불후의 명작을 남긴 유명작가의 작품들이다. 이는 19세기 인류가 고민했던 주제들이 현대인들의 고뇌와 흡사하다는 데 있다. 위대한 문학은 시간이 지날수록 빛을 발하기 때문이다.

This essay attempts a historical examination of educational function of the novel. It pays attention to the eighteenth century sentimentalism, and its historical vicissitudes up to early twenties century. The eighteenth century is the period in which debates on the nature of emotion and its moral and aesthetic role have passionately taken place and the modern paradigm of thought on affect has been formed. This is why "affect revival phenomenon" in the late twenties century goes back to this period. This essay finds in Adam Smith the most sophisticated arguments on sympathy in their relation to the development of the novel; it examines the relationship of Smith's argument with modern novel in the tradition of sentimentalism, and its revision in modernist novel. Through this examination, it discusses how cognitive and non-cognitive approaches, the two representative positions in contemporary thinking on emotion/affect, have revised and transformed the eighteenth century sentimentalism.

As a sequel to the previous paper Gou Gu Shu in the 18th century Chosun, we study the development of Chosun mathematics by investigating that of Gou Gu Shu in the 19th century. We investigate Gou Gu Shu obtained by Hong Gil Ju, Nam Byung Gil, Lee Sang Hyuk and Cho Hee Soon among others and find some characters of the 19th century Gou Gu Shu in Chosun.

This study was conducted to examine the chronology of Taesil Seokham(Taesil Stone Boxes) stored in Taesil of the Joseon Palace and classify the styles to discuss how these boxes have developed. By doing so, this study defined the archaeological styles of taesil seokhams in the chronological order. Although taesil seokhams are placed when taesil are first created, they do not have any texts engraved on them and it is difficult to gain information only from examining taesil seokham. However, Taejiseok(memorial stones buried in Taesil) and Agibi(gravestones buried in Taesil) were created along with taesil. These resources were examined and compared with literature records to find when each taesil seokhams was created. The critical elements to consider for the chronological arrangement were both the cover and container of the boxes and the transition of their style could be classified into four major stages. In detail, the Joseon Dynasty's taesil seokhams initially inherited the style of the Goryeo Dynasty to be formed into rectangular boxes. Through the transition of the mid and late 15th Century, the semi-circular cover with cylindrical container became the popular style in the late 15th Century. In the late 16th Century, the style of the previous period was further developed to add some decorative elements, such as projecting ornaments, but the ornaments were added for functional purposes rather than artistic purposes. However, the style went back to the semi-circular cover with cylindrical container in the early 17th Century. From the mid 17th Century, various styles appeared with ornaments only on the cover, cone-shaped cover with no ornament, or mortar-like container. However, a new style of cone-shaped cover with ornament emerged between the early and mid 18th Century and continued to stay until the mid 18th Century. In the mid 18th Century, the cover remained unchanged, but the container became a keyhole-shaped space with one side forming a "ㄷ" shape. However, in the late 18th Century, the most typical style of the semi-circular cover with cylindrical container reappeared to show that this is the most universal style. Last, in the mid 19th Century, the cover changed from semi-circular to rectangular with flat top. After this, the taesil seokhams began to disappear. In terms of style, it can be classified into four stages. In the early Joseon Dynasty, the taesil seokhams were underdeveloped and inherited the style of the Goryeo Dynasty (Stage I; 1401~mid-15C), but Joseon's unique style began to develop from the late 15th Century (Stage II; 1477~1641). After that, partial ornaments were added for adornment (Stage III; 1660~1754), but the typical style reappeared in the late 18th Century to finally degrade in the late Joseon Dynasty of the mid 19th Century (Stage IV; 1790~1874). This arrangement of style and chronology would greatly help archaeologists anticipate the time and owner of taesil seokhams even if only taesil seokhams are discovered without any records. * Tae(胎) : Placenta and umbilical cord * Taesil(胎室) : A facility(chamber) of burying Tae(胎) in rite when royal descendants are born.

The purpose of this study is to examine the features of the curriculum of Chosun-Sanhak(朝鮮算學), the mathematics of Chosun Dynasty in the 17th to 18th century. The results of this study are as follows. First, the goal of education, teaching-learning method and assessment of Chosun-Sanhak in the 17th to 18th century had not changed since the 15th century. Second, the changes in the field of the organization of mathematical contents were observed. Chosun-Sanhak in that time was higher in the hierarchy than in the 15th to 16th century. The share of the equation and geometry had increased and various topics of mathematics had been studied as well. Third, in the field of the characteristics of mathematical contents, the influx of European mathematics and the uniqueness of Chosun-Sanhak had been observed. In conclusion, The 17th to 18th century was the time when Chosun-Sanhak had pursued the identity escaping from the effects of Chinese-Sanhak.
