In this paper, I review the origins, activities, and influences on the future mathematical development of the Analytical Society of Cambridge. The story of the late 18th century Scotland mathematicians and the early 19th century Cambridge mathematician such as Woodhouse, and the Analytical Society's history show that the Analytical Society wasn't a completely new and reformative meeting. This article reveals that the new analytical studies developed characteristically in Britain's specific intellectual and social context of the late 18th century and the early 19th century.

Our study aimed to analyze and reinterpret, by an acoustic approach, the descriptions of the 18th century prosody and introduce the figurative pronunciation system, which is the International Phonetic Alphabet pioneer. Our methodology compares and analyzes grammars and documents on the transcription system and restructures the prosodic structure. It is certain that the 18th century grammarians widely accepted the prosody theories made by Arnauld & Lancelot of the seventeenth century. In particular, grammar scholars accepted the dichotomous classification of the accent structures as prosodic and oratorical accents. The prosodic accent has a relation to intonation, and the oratorical accent has as its key elements intonation and intensity. Regarding the temporal structure, the lengthening of the final syllable was observed systematically by grammarians of the 18th century. This time structure is similar to that of today. Therefore, we can conclude that the final elongation, an essential characteristic of the modern French accent, has already played an imbued role in 18th century prosody. Despite this, the 18th century grammarians did not assign it the status of accent, as it was a stereotype that matches accent with intonation.

This study investigated the contents related to the plane figures in the geometry domains of Joseon-Sanhak in the late 18th century and focused on changes in explanations and calculation methods related to plane figures, the rigor of mathematical logic in the problem-solving process, and the newly emerged mathematical topics. For this purpose, We analyzed , and written in the late 18th century and and written in the previous period. The results of this study are as follows. First, an explanation that pays attention to the figures as an object of inquiry, not as a measurement object, and a case of additional presentation or replacing the existing solution method was found. Second, descriptions of the validity of calculations in some problems, explanations through diagrams with figure diagrams, clear perceptions of approximations and explanations of more precise approximation were representative examples of pursuing the rigor of mathematical logic. Lastly, the new geometric domain theme in the late 18th century was Palsun corresponding to today's trigonometric functions and example of extending the relationship between the components of the triangle to a general triangle. Joseon-Sanhak cases in the late 18th century are the meaningful materials which explain the gradual acceptance of the theoretical and argumentative style of Western mathematics

신고전주의 미학사상은 고대의 고전주의적 유산의 18세기적 특수화다. 신고전주의는 고전주의의 연장이지만 18세기라고 하는 특수한 시대적 환경속에서 당대의 전반적인 요구 -논리화와 과학화-에 부응하고자 시작한 미학적 대처 방안이었다. (중략)

We estimated pigments and painting techniques with nondestructive analysis for Yu Eonho's portrait made in the eighteenth century, then compared with 11 portraits and painting characteristics at that time. The pigments used to Yu Eon-ho's portrait include lead white, yellow dye, cinnabar, minium, and pink dye, malachite, azurite, iron oxide red and brown dye, blue and pink dye for purple. In the result compared with painted pigments of 11 portraits, iron oxide red without cinnabar was used on the face part and organic green dye only was used instead of inorganic pigments on the other side of clothing after Yu Eonho's portraits portrait. This study is show the painting techniques on the portraits in the late $18^{th}$ century. We expect to use as useful referencing data for the study on the coloring technique of a portrait in the late Joseon Dynasty.

Skull base height increases significantly with better nutrition and health conditions. With coordinate caliper or by subtraction, skull base height is easily measured. To examine nutrition and health condition of MIA(missing in action) during the Korean War and people who lived during the 17-18 centry of the Late Chosun. This study is focused on the change of skull base height through time as seen in comparing 83 MIA cranium and 12 17-18 centry cranium of Korea with 219 modern American middle class adult cranium(Terry Collection and forensic skeleton). To sum up, nutritional condition of MIA is not significantly changed, as seen in comparing with nutritional condition of 17-18 century people.

This study analyzed the pigments used in two portraits of Sim Hui-su using scanning electron microscopy/energy dispersive spectroscopy(SEM/EDS), X-ray diffraction(XRD) analysis, and microscopic observation, and then compared the results to those from nondestructive analysis. It was estimated that cinnabar/vermilion and minium were used for the red pigment, azurite for the blue pigment, atacamite for the green pigment, and lead white for the white pigment. These results were compared to the pigments of six portraits with a similar format, full-length official-attire portraits from the $17-18^{th}$ century Joseon period. It was revealed that the composition of the pigments used in the portraits varied depending on the date of production. Iron oxide, another red pigment, was used in the $18^{th}$ century. As for the blue colorant, smalt was used in the late $18^{th}$ century, whereas it was absent until the early $18^{th}$ century.

This article is a follow-up on the concept of philosopher/writer and its transformation in the Age of Enlightenment - 1. the dictionary meaning of the term 'philosopher/writer' and the origins of 'literary fields' of the Enlightenment era. In this article, we analyzed changes in the literary field in the late $17^{th}$ century after the expansion of the publishing market. We examined the conflict surrounding philosophers' identifying between modern and traditional philosophers. We have validated that the formation of new readers has made traditional philosophers more sensitive to the 'horizon of expectations' of readers. Some biographical works are also one of our concern. By the end of the $17^{th}$ century, philosophers and writers suddenly became objects of biographical works unlike in the past. Through our research, we found that readers have sought the arrival of a new hero, a great philosopher or a great writer, that will lead a new era, and due to this anticipation, it has led to the publication of biographical works. In this process, we have revealed conceptual changes about authors, writers, philosophers, and so on. In the next article, we will continue advanced discussion on the concept of philosopher/writer.

The purpose of this study is to examine how the cultural aspects of the publication of literary collections have been changed from its time throughout the entire Joseon Dynasty. At the royal court in the early Joseon Dynasty, the need for publication of the literary collections has consistently arisen to preserve writings of the noted sages, and the Joseon government was also taking the lead and promoting the publication of the literary collections. From the 16th to the early 18th century, the publication was intensively made at the local governments led by local governors. From the 17th to the early to middle of the 18th century, the finances of local governments were limited with the changed taxation system, and there had been a dramatic decrease in the number of literary publication projects. On the other hand, with the sudden increase of the number of Seowons during the reign of King Sukjong, the focus of the literary publication was moved to Seowon from the 18th to the 19th century. After the enforcement of the Seowon Abolition Decree, the collections were still published at Seowons, however from the end of 19th century, the publication of literary collections had been explosively made by aristocrats who did not belong to the institution of Seowon or could not receive Seowon's support, which spreaded over the entire Yangban culture.
