천문학회 교육홍보위원회 산하 해외교육지원단에서는 2016, 7년 1, 2기 원정대에 이어 3기 원정대 6명을 선발하여 2018년 9월 17-21일 5일 동안 캄보디아 시소폰의 Xavier Jesuit School에서 약 30명의 중등 과학 선생님들을 대상으로 천문연수를 진행하였다. 3기 원정대에서는 다양한 경험과 경력을 가진 대원들이 참여하게 되어 망원경을 활용한 실습 수업 뿐만 아니라 연수에 참여한 과학 선생님들이 직접 수업에 활용할 수 있는 기본 천문학 수업들을 포함하였다. 그리고 최신의 천문학 연구를 소개할 수 있는 현대 천문학 수업을 준비하여 참가자들에게 더 다채로운 천문학 세계를 소개할 수 있었다. 해외교육지원단에서는 캄보디아와 같이 천문학 교육에 소외된 나라의 천문교육지원 사업을 지속적으로 지원할 계획이며 특히, 각 지역의 과학 교사들에게 연수기회를 제공함으로써 교육자들을 통해 각 지역의 어린 학생들이 천문학을 접할 수 있는 기회가 많아지기를 희망한다. 또한 직접 연수를 받은 과학 교사들의 천문학에 대한 관심을 높이고 천문학 연구의 필요성을 인지할 수 있게 도울 예정이다.

What is unknown about Leibniz (Gottfried Wilhelm Leibniz, 1646~1716), a great philosopher and mathematician, is that he inquired about ginseng. Why Leibniz, one of the leading figures of the Enlightenment, became interested in ginseng? This paper excavates Leibniz's references on ginseng in his vast amount of correspondences and traces the path of his personal life and cultural context where the question about ginseng arose. From the sixteenth century, Europe saw a notable growth of medical botany, due to the rediscovery of such Greek-texts as Materia Medica and the introduction of a variety of new plants from the New World. In the same context, ginseng, the renowned panacea of the Old World began to appear in a number of European travelogues. As an important part of mercantilistic projects, major scientific academies in Europe embarked on the researches of valuable foreign plants including ginseng. Leibniz visited such scientific academies as the Royal Society in London and $Acad{\acute{e}}mie$ royale des sciences in Paris, and envisioned to establish such scientific society in Germany. When Leibniz visited Rome, he began to form a close relationship with Jesuit missionaries. That opportunity amplified his intellectual curiosity about China and China's famous medicine, ginseng. He inquired about the properties of ginseng to Grimaldi and Bouvet who were the main figures in Jesuit China mission. This article demonstrates ginseng, the unnoticed subject in the Enlightenment, could be an important clue that interweaves the academic landscape, the interactions among the intellectuals, and the mercantilistic expansion of Europe in the late 17th century.

The systems of aromatic amines such as aniline, N,N-dimethylaniline and N,N-diethylaniline with iodine or iodine monochloride in carbon tetrachloride have been examined spectrophotometrically. The results indicate the formation of one to one molecular complexes. The equilibrium constants obtained at room temperature for formation of the complexes are as follows: $C_6H_5NH_2{\cdot}I_2\;2.05$, $C_6H_5N(CH_3)_2{\cdot}I_2\;15.2$, $C_6H_5N(C_2H_5)_2{\cdot}I_2\;35.5$, $C_6H_5NH_2{\cdot}ICl\;18.5$, $C_6H_5N(CH_3)_2{\cdot}ICl\;25.6$, and $C_6H_5N(C_2H_5)_2\;42.0$ l $mole^{-1}$.

The interactions of fluorobenzene with iodine monochloride, iodine monobromide, bromine and chlorine in carbon tetrachloride solution have been examined through ultraviolet spectrophotometric measurements. The results indicate the formation of one to one molecular complexes, $C_6H_5F{\cdot}ICl$, $C_6H_5F{\cdot}IBr$, $C_6H_5F{\cdot}Br_2$, and $C_6H_5F{\cdot}Cl_2$ in solution. The equilibrium constants obtained at room temperature for the formation of these four complexes are 0.161, 0.072, 0.045 and 0.035 l $mole^{-1}$, respectively. Comparison of these results with those reported in the literature on other complexes of similar type reveals that the relative stabilities of these complexes decrease in the following orders: ICl>IBr>$I_2$>$Br_2$>$Cl_2$ $C_6H_6$>$C_6H_5Br$>$C_6H_5Cl$>$C_6H_5F$

This study examines the establishment of Sea-po (서포) in the opening period of Korea at the end of the 19th century. The role they played, the particular situations and their geographical characteristics are researched, The earliest sea-po was Koh-je-hong sea-po, which was established in Tae­kwang-kyo at the end of 1880s. Around 1905, a specialised book distribution system was set up with establishement of Chu-han-yung book store, Kim-sang-man book store, Jesuit book store, Tae-dong su-si, Kae-myung sea-kwan, Tong-wha seo-kwan. The owners of the seo-pos were pioneers in introducing modern culture with nationalistic consciousness, although they were primarily businessmen and their social origins varied. The primary role of seo-pos was selling a variety of books but some combined printing and publication of books as well. It seems that publication business took roots around 1908, though it is difficult to know the accurate dates of first attempts. Some sea-pas offered book rental services for poor people who could not easily afford to purchase books. A certain amount of deposit had to be paid to benefit from the services. Jesuit Bookstore in Pyungyang had a library facility with a large stock or books in the same building open to public for free. These sea-pas started mainly in Seoul and Pyungyang, which were traditional centers for economic and cultural affairs. Early introduction of foreign cultures and commercial developments in these areas contributed to the establishment of sea-pos. The sea-po which took charge of book distribution in the provinces was set up around 1906. One of the important findings of this study is that the geographical distribution of sea-po shows the following three characteristics. First is that the area such as Seoul, Taegu and Chunju were the traditional centers of publishing culture from which Pang­gak-bon(방각본) emerged. Second characteristic is Pyungyang and the surrounding Pyungbuk province, and harbors like Inchon and Pusan, which had the benefits of early spread of modem cultures. Third characteristic is Kaesung and the surrounding Hwanghae province which bridged Pyungyang and Seoul. The reception of foreign cultures stimulated the commercial spirits traditionally attributed to Kaesung to establish sea-pas most actively.

The purpose of this study is to consider the influence of the French Royal Academy of Science on the European mapping of China in the eighteenth century. For this, the historical background of French Jesuits mission of mathematicians sent to China by Louis XIV in 1685 was examined. It was found that making astronomical observations for the determination of Chinese geographic coordinates was one important reason of the French Jesuit mission. Secondly, Cassini instructed the longitude determination method to the missionaries and they reported their survey results to the Academy as correspondence member. Thirdly, the cartographic materials they accumulated in the first state were not sufficient to change the map of China. But after 1700, the map of China was broken with the Ptolemaic tradition and the longitude of Peking was moved westward about $20^{\circ}$. This reduced the width of China. Fourthly, the French Jesuit contributed to the making of Huangyu quanlan tu. The manuscipt was sent to France and it was published in d'Anvill's atlas. And his map was used as a standard map of China for more than 100 years.

We can witness the recent surge of interest in the controversy over the scientific status of mathematics among Jesuit Aristotelians around 1600. Following the lead of Wallace, Dear, and Mancosu, I propose to look into this controversy in more detail. For this purpose, I shall focus on Biancani's discussion of scientiae mediae in his dissertation on the nature of mathematics. From Dear's and Wallace's discussions, we can gather a relatively nice overview of the debate between those who championed the scientific status of mathematics and those who denied it. But it is one thing to fathom the general motivation of the disputation, quite another to appreciate the subtleties of dialectical strategies and tactics involved in it. It is exactly at this stage when we have to face some difficulties in understanding the point of Biancani's views on scientiae mediae. Though silent on the problem of scientiae mediae, Mancosu's discussions of the Jesuit Aristotelians' views on potissima demonstrations, mathematical explanations, and the problem of cause are of utmost importance in this regard, both historically and philosophically. I will carefully examine and criticize some of Mancosu's interpretations of Piccolomini's and Biancani's views in order to approach more closely what was really at stake in the controversy.
