삼별초정부의 대몽항전과 국내외 정세 변화

김윤곤 ( Yoon Gon Kim ) 한국중세사학회 2004 한국중세사연구 Vol.0 No.17

The government of Sambyelcho was proud of succeeding to tradition of unified Samhan, and fighted against the Mongols. Gyegyeong government, however, accepted the demand of the Mongols, and after returning to the capital from Ganghwagyeong to Gyegyeong, attacked the government of Sambyelcho, and allied itself with the attack of Japan. Combined Goryeo-Mongol forces were busily preparing for the war to rule the sea again and attack Japan. If combined Goryeo-Mongol forces should gain control over anti-Mongol, especially sea strength, they could break through defense net of Masan sea, and at the same time attack Japan and command the sea again. This led to the struggle between Sambyelcho and Gyegeong governments. Later defeat of Sambyelcho government and retreat into Jejudo, at least a part, resulted from the weakened defense system in Jindo due to this struggle. When the Millitary government collapsed and was broken into Sambyelcho and Gyegeong governments, the intellectuals of Confucianism and Buddhism were also divided into two parts according to their doctrines or situations. Later, however, a large number of them returned to Gyegyeong and participated in the Gyegyeong government. There are several evidences that even some of the intellectuals who took part in the making of Goryeo Tripitaka returned to Gyegyeong, and shouldered the burdens of high office later. Until those times, only three countries, Goryeo, Sung, and Khitan had ever held Tripitakas. However, two countries except Goryeo had already collapsed, and could not complement Tripitaka system and seek the promotion of Buddhism. Therefore, the intellectuals of Confucianism and Buddhism seemed to believe that, by making unified version of Tripitaka and flourishing Buddhism, Goryeo would rise and develop into center of Buddhism in East Asian world, and its authorities as an independent state would be greatly promoted.

나옹 (懶翁) 혜근 (慧勤)의 회암사 (檜巖寺) 중창과 반불논 (反佛論)의 제압기도

김윤곤(Yoon Gon Kim) 대구사학회 2001 대구사학 Vol.62 No.1

Hwoi-Am Temple(檜巖寺), located at Chun-Bo mountain(天寶山) in Yang-Ju Gun, Kyung-Ki DO, was destroyed by the war in the late fourteenth century, and then it had been reconstructed for two years from 1374-1376 by Naong Haekeun(懶 惠勤, 1320-1376). In the middle of the reconstruction, the destruction of temples by Anti-Buddhists(反佛論者) and rejection of Buddhism were increased in power. In addition the political chaos was continuously remained in the society due to the transition of two countries from Won(元) to Myung(明), and the late stage of King Kong-Mins reign(恭愍王代). Under the conflict between these powers and reinforcement of independent national sovereignty as well as Sung Confucionism(性理學), it is assumed that the influential supporters of Buddhism including Naong(懶翁) attempted to rebuild the Hwoi-Am Temple(檜巖寺) because they believed that it might expand the power of weakened Buddhism. In the Moon-Su Hwoi(文殊會), which was held at the time of completion, numerous men and women came in crowds from central or country side to contribute or to make offerings to the temple. Sahunbu(司憲府) and Dodang(都堂) could not stop them even though they tried to block up and close the temple. Of cowse they predicted an attack from the anti-Buddhists(反佛論者). Nevertheless they attempted to reconstmct the temple for internal unity of Zen Buddhism(禪宗) and strength of Buddhist authority. Also they might experiment it under the beliefs of that the huge scaled structure with two hundred sixty two chambers(262間) and its splendor would attain dignity in the dominated situation and rule continuously over absolute supremacy. However because of attacks from Sahunbu(司憲府) and Dodang(都堂), resulting Naongs death, prevented them to accomplish the very first intension of all. The reconstruction of Hwoi-Am Temple(檜巖司) is recorded fully in Chunbosan Hwoi-Am Sa Sujoki(『天賓山檜巖寺修造記』) by Lee-sek(李穡, 1328-1396). This book explains about the structure of the temple, which is divided into three single story with high, medium and low levels in general, revolving around the central axis of main entrance(正門) and Bokangchun(普光殿). Its stairs are divided into three equal parts, which consist of left, middle and right in order. The purpose of these divisions are to distinguish social standing and status of visitors. It is possible to determine that the appearance of building and its entrance of temple in Koryo dynasty represents the distinction of social classes. If we compare the whole structure of the temple to human body, the upper part of the building is applicable to the head part, the middle as the chest and abdomen, and finally the low part as the lower part of the body. This Division may be resulted from the various classes of visitors, such as the royal family including the king, the nobility and the various Buddhist monks as well as the common people, and their place for charity and accommodation. From the fact mentioned above, the background of reconstruction of Hwoi-Am Temple(檜巖寺), achieved by Naong(懶翁) at the end of Koryo dynasty, is based on the preparation for Anti-Buddhism(反佛論) and the cultivation for supporters of Buddhism. Also the three equal parts of its structure are characterizing the social classification. Although the transition from Koryo to Chosun and the ideology of domination from Buddhism to Sung Confucianism(性理學) changed the society, the Hwoi-Am Temple(檜巖寺) has been preserved its privilege because it is not only located near Seoul but also the structure of the building was appropriate for the royal family and nobility to observe the Buddhist ceremonies.

천연 고분자인 한천 하이드로젤은 다량의 수분을 함유하고 있기 때문에 접촉각이 매우 작은 극친수성 표면성질을 갖게 된다. 본 연구에서는 다양한 범위의 소수성을 갖는 한천 하이드로젤을 제조하였다. 이소시아네이트기를 갖는 알킬사슬을 아가로스 분자에 도입하여 소수성 아가로스 분자를 합성하였다. 최적 접목도를 갖는 아가로스 분자와 순수 한천분자와의 혼합비를 조절하여 다양한 친수성/소수성 정도(접촉각 10~90°)를 갖는 한천 하이드로젤을 제조할 수 있었고 팽윤비 측정, 내부구조 분석, 기계적 물성 분석 및 표면 접촉각 측정을 통해 물리적, 구조적 특성을 확인하였다. 소수성 한천 하이드로젤은 미생물배지, 전기영동 젤, 조직공학용 생체재료, 나아가 기능성 물질의 동물대체 효능시험을 위한 맞춤형 시편으로 다양하게 활용될 수 있다. Natural polymer agar-forming hydrogel exhibits such a high hydrophilic character for absorbing large quantities of water in a 3D cross-linked network structure. This study presents an advanced integrative strategy to control the hydrophobicity of the agar hydrogel. We synthesized the hydrophobically modified agarose (HMA, Agarose-g-C18) substituted with octadecyl chains, consisting of the optimized degree of substitution (DS). Then, in situ hydrogel forming of agars with HMAs, varying mixing ratios, generated the agar hydrogels that possess various hydrophilic/hydrophobic balances. We analyzed the physical and structural properties via DSC, SEM, UTM, and contact angle for substitution effects. Overall, this new strategy to prepare the agar hydrogel with hydrophilic/hydrophobic balances would greatly serve to facilitate a wide array of the agars used in microorganism culturing, electrophoresis, tissue engineering, cosmetic research, etc.

Abnormal glycosylation can significantly affect the intrinsic functions (i.e., stability and solubility) of proteins and the extrinsic protein interactions with other biomolecules. For example, recombinant glycoprotein therapeutics needs proper glycosylation for optimal drug efficacy. Therefore, there has been a strong demand for rapid, sensitive and high-throughput glycomics tools for real-time monitoring and fast validation of the biotherapeutics glycosylation. Although liquid chromatography tandem mass spectrometry (LC-MS/MS) is one of the most powerful tools for the characterization of glycan structures, it is generally time consuming and requires highly skilled personnel to collect the data and analyze the results. Recently, as an alternative method, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-MS), which is a fast, robust and easy-to-use instrumentation, has been used for quantitative glycomics with various chemical derivatization techniques. In this review, we highlight the recent advances in MALDI-MS based quantitative glycan analysis according to the chemical derivatization strategies. Moreover, we address the application of MALDIMS for high-throughput glycan analysis in many fields of clinical and biochemical engineering.
