From the time of his studies in Japan until his return to Korea in 1907, Yu Kilchun’s acquaintances can be divided into three categories: people Yu met during his studies at Keio Gijuku, people Yu met to plan a coup during his exile, and people who participated in Tonga Ch’ŏngnyŏnhoe and Irhan Tongjihoe from 1906.Although his time at Keio Gijuku was not long, the people he met during his studies bonded strongly, and a network of academic contacts was formed through reunions. These connections played a crucial role when Yu was active in the political scene in 1894 during the Kabo Reform period. After Yu left Korea on an exile following Emperor Kojong’s flight to the Russian legation in February 1896, he established a new network of acquaintances. Specifically, his journals from 1901 revealed that Yu was searching for people in Shizuoka, Gifu, and Hokkaido, who would take part in his conspiracy. Since he came to Tokyo after serving his time at the Ogasawara Islands, he worked with Tonga Ch’ŏngnyŏnhoe and Irhan Tongjihoe. Additionally, this paper demonstrated that he had connections with the Tonghak Order, and that it was possible for Yu to express his opinions in the press through O Sech’ang and Yi Inchik, who were residing in Korea. Around the same time, he also traveled around Yamanashi, Nagano, Toyama, and Fukui, and made efforts to facilitate trade between Korea and Japan. Such efforts were feasible thanks to the network of collaborators in Korea.

余基春及其熟人网络研究（1881-1907）

从留学日本到 1907 年返回韩国，余基春的熟人大致可以分为三类：余在京王大学学习时遇到的人，余在流放期间遇到的策划政变的人，以及1906年参加汤加Ch'ŏngnyŏnhoe和Irhan Tongjihoe。虽然他在京王纪宿的时间不长，但他在学习期间遇到的人关系密切，并通过团聚形成了学术联系网络。这些联系在 1894 年卡博改革时期于 1894 年活跃在政治舞台上时发挥了至关重要的作用。在高宗皇帝于 1896 年 2 月逃往俄罗斯公使馆后，禹离开韩国流亡国外后，他建立了一个新的熟人网络。具体而言，他从 1901 年开始的日记显示，于在岐阜县静冈市寻找人，和北海道，谁会参与他的阴谋。在小笠原群岛服役后来到东京，他与汤加Ch'ŏngnyŏnhoe和Irhan Tongjihoe一起工作。此外，这篇论文表明他与东鹤教团有联系，而且他有可能通过居住在韩国的 O Sech'ang 和 Yi Inchik 在媒体上表达他的意见。大约在同一时期，他还周游山梨、长野、富山和福井，努力促进韩日之间的贸易。由于韩国的合作者网络，这些努力是可行的。这篇论文表明他与东鹤教团有联系，而且他有可能通过居住在韩国的 O Sech'ang 和 Yi Inchik 在媒体上表达他的意见。大约在同一时期，他还周游山梨、长野、富山和福井，努力促进韩日之间的贸易。由于韩国的合作者网络，这些努力是可行的。这篇论文表明他与东鹤教团有联系，而且他有可能通过居住在韩国的 O Sech'ang 和 Yi Inchik 在媒体上表达他的意见。大约在同一时期，他还周游山梨、长野、富山和福井，努力促进韩日之间的贸易。由于韩国的合作者网络，这些努力是可行的。
