崔奎成 동국사학회 1981 동국사학 Vol.16 No.-
이 小稿에서 筆者가 意?하는 바는 惠宗으로부터 顯宗末年까지의 期間을 設定하여 顯宗朝를 시작으로 前後의 2期로 兩分하고, 각 시기마다 어떠한 내용의 對女眞政策이 추진되었으며, 그 결과가 축적되어 高麗의 北万政策을 변모시켜 나갔는가를 밝혀 보려고 한 것이다. 특히 高麗史와 高麗史節要에 보이는 女眞族의 來往記錄을 중점적으로 分析檢討하여, 高麗의 北進政策의 推進過程에서 發生하는 女眞問題를 밝혀봄으로써 이때까지 비교적 관심을 기울이지 않았던 이 ㅇㅇ의 硏究에 조그만 보탬이 되고자 하는 것이다.

崔圭成 상명대학교 논문집 1987 상명대학교논문집 Vol.19 No.-
The early power base of the Kungye regime was not on the traditional aristrcrats of Silla who were still imbued with the bone-rank (kolp'um) system, but on the local groups who wee anti-Silla. The regime began to be powerful with the occupation of Myongju-song and became strong enough founding a new state by a successful conquest of the nothern territory of Silla. Its position was further strengthened by the voluntary surrender of Wang Kon who was influential in the valley of Yesong River. Kungye was able to ally himself with the groups in the P'aeso area who were the people of Koguryo, and it was this alliance that made him found the state of Koryo as the successor to the former Koguryo kingdom. In the meantime, Kungye accepted the recommendation by Wang Yung and established his control over Songak which was the power base of Wang Kon. It was this control that he was able to make it his capital later. Kungye gradually became estranged from the people in P'aeso with the consolidation of his political power and the territorial expansion south to Jukryong, further beyond the old border of Koguryo. Subsequnetly, he renamed his state Majin and built a new capital. Majin means a "great country of the East" in Sanskrit. It is believed that Kungye was a monk and had some knowledge of Sanskrit. He must have hoped that the Sanskrit name would win public confidence in his kingdom and bring devine protection to it. At the same time, the new name seems to have expressed his intention to annex Silla and to build a great state which would be much bigger than Koguryo. His autonomous reign title of Mut'ae should be also understood to show his spirit of independence and self-confidence both internally and externally. The title was apparently disadvantageous in his relation with China. But be seems not to have minded of the diplomatic disadvantage. Kungye once more gave his state a new name. T'aebong, in Ⅲ. In this new name, we see his strong will to achieve a national unification that would embrace the Later Three Kingdoms and all their people. thus Kungye's renaming of the state and his transfer of the capital seem to have been mainly due to the growth of his power, not due to his entertaining of a superstitious belief and geomantic theories.

Cd(Ⅱ)이온과 N_1S_3및 N_2S_4포단드와의 착물형성에 관한 연구
최규성,이상천,김용성,강동현 慶南大學校 附設 工業技術硏究所 2003 硏究論文集 Vol.21 No.1
황을 포함하는 포단드 리간드인 tri(2-phenylthio-ethyl)amine (Podand N_1S_3)과 tetra(phenylthio-2-ethyl)ethylenediamine (Podand N_2S_4)의 합성을 확인하고, 이들의 양성자 첨가반응에 의한 평형상수(protonation constant)와 중금속 이온인 Cd(Ⅱ) 이온과의 착물형성에 따르는 안정도상수(stability constant)를 양성자들 첨가한 95% MeOH 용액에서 전위차 적정법을 사용하여 측정하였다. 리간드에 대한 양성자 첨가반응의 평형상수는 Podand N_1S_3 보다는 Podand N_2S_4 리간드가 큰 값을 보였다. 또한 Cd(Ⅱ) 이온과의 착물형성에 따르는 안정도상수의 크기도 Podand N_2S_4가 Podand N_1S_3 리간드보다 큰 값을 보이고 있다. 양성자 첨가반응에 대한 평형상수와 안정도상수를 여러 온도에서 측정하여 엔탈피 및 엔트로피의 열역학적 파라미터를 구한 결과 착물형성에 대한 -ΔH는 Podand N_2S_4가 Podand N_1S_3보다 크게 나타났으며, TΔS는 Podand N_1S_3보다는 Podand N_2S_4가 큰 값을 보였다. The protonation and stability constant of complexation of Cd(Ⅱ) ion with sulfur-containing podand ligands such as tri(phenylthio-2-ethyl)amine (Podand-N_1S_3) and tetra(phenylthio-2-ethyl)ethylenediamine (Podand N_2S_4)have been determined by using potentiometric titration in 95% MeOH at various temperature. We observed that Podand N_2S_4 ligand showed the largest protonation constant. The values of not only protonation constant but also stability constant of Cd(Ⅱ) ion were increased Podand N_1S_3 rather than Podand N_2S_4. In addition, thermodynamic parameters ΔH and changes of Pb(Ⅱ) ion complexes is Podand N_1S_3 < Podand N_2S_4.

최규성 慶南大學校 附設 基礎科學硏究所 1999 硏究論文集 Vol.13 No.-
The protonation constants for the macrocyclic ligands containing nitrogen and oxygen donors, 1,15-diaza-3,4:12,13-dibenzo-5,8,11-trioxa cycloheptadecane(NEOD), and 1,12,15-triaza-3,4:9,10-dibenzo-5,8-dioxa cycloheptadecane(NDOE) have been determined by potentiometric titration at 25℃. In order to obtain the enthalpy and entropy changes of complexation reaction of Zn(Ⅱ) ion with these ligands, the stability constants have been measured by polarographic method at 15-45℃. Protonation constants and stability constants have been found to be effected by the numbers of donor atoms, the basicities of the macrocyclic ligands, and chelate effect. The complexation reactions are exothermic and show the positive entropy changes. ¹H-NMR studies showed that the stepwise additions of Zn(Ⅱ) ion into the macrocyclic ligands of constant concentration induced two major spectral changes. First, the chemical shifts were linear up to 1 : 1 Zn(Ⅱ)-ligand ratio. These results indicates that the 1 : 1 Zn(Ⅱ)-ligand complexes are formed. Second, various magnitudes of Zn(Ⅱ) ion induced chemical shifts were observed with the same ligands, which indicates the efficient formation of donor atoms-Zn(Ⅱ) ion complexes. The large chemical shifts of protons learest aside the nitrogen were noticeable with the addition of Zn(Ⅱ) ion.
