朝鮮後期 宮中 御筆 收藏과 印刊 : 1725년 『乙巳列聖御筆刊進及景宗大王御筆屛風謄錄』의 분석

黃晶淵(황정연) 한국학중앙연구원 2004 장서각 Vol.- No.12

This paper deals with royal collection of calligraphic works by successive kings of the Chos?n dynasty(1392`1910) and procedures concerning printing them into woodblock or lithographic types. As did records of the superintendency for court events, ?igwe(儀軌), preliminary records of ?igwe named d?ngnok(謄錄) played a model role to handle all procedures of court events. Thus, the main source in this paper, ?lsa y?lls?ng ?p'il ganjin g?p ky?ngjong taewang ?p'il by?ngp'ung d?ngnok(乙巳列聖御筆刊進及景宗大王御筆屛風謄錄), Record of Procedures Making Albums of Royal Calligraphic Works and Screen of Calligraphy by King Ky?ngjong in the cyclical year, ?lsa, 1725, gives us various information of compiling and publishing royal calligraphic works into both woodblock and lithographic prints. According to this record, after over 300 pieces of prints were made, some were preserved in palace or some were bestowed to the royal families and government officials. Such a large amount of prints caused to make many royal calligraphic prints kept in palaces since the seventeenth century when printing of royal calligraphic works has started. Given the history of collection of royal calligraphic works in palace, the era of King Y?ngjo(r.1724~1776) is a bridge that links between the eras of King Sukjong(r.1674~1720) and King Ch?ngjo(r.1776~1800), because royal collection has been gradually expanded during the reigns of these three kings. In 1725, calligraphic works by successive kings were printed into the two types: woodblock and lithography. In order to make them, by King Y?ngjo's order, the officials began gathering authentic royal calligraphy, then many skillful artisans sent from various branches of government offices carved kings' writings on wooden or lithographic plates, rubbed them with ink, and finally mounted them as a type of album or folding screen. It was revealed that though the Bureau of Royal Descendants(宗親府) governed all procedures in cooperation with other government offices, King Y?ngjo always made an important decision. Sometimes he wrote a predecessor's name as a label of his calligraphy, a symbolic activity to show his respect for the previous king. More details concerning making prints are discussed in this paper. In conclusion, thanks to the printing huge amount of royal calligraphy in palace and bestowing prints of royal calligraphy on officials, private collectors have been encouraged to posses them as precious ink traces. Probably it was one of the main reasons to make private collection of royal paintings and calligraphy enlarged since the seventeenth century.

The Mo-yu¨an hui-kuan (墨綠彙觀, preface. 1742) by An Ch´i (安岐:1683-after 1745) is a renowned catalogue of Chinese painting and calligraphy, that contains rare examples and provides a variety of information for extant works. An Ch´i was a wealthy Korean salt merchant and started his career as a collector and connoisseur in his early life. According to Hsiao Shih`s (蕭奭) Yung-hsien-lu (永憲錄), An Ch´i´s grand father and father were financially supported by Ming Ju(明珠:1635-1708), an influential politician under the K`ang-hsi emperor(r.1662-1722). Not only were they engaged in the salt business in Tien-jin and Yang-chou but also became the nouveau riche, even dominating other merchants` commercial places. During the first quarter of the eighteenth century An Ch´i could be one of the most important merchants in the Liang-hual(兩淮) area. Being naturally interested in painting, An Ch´i had occasionally written the catalogue during his life time and completed it in 1745 just before his death. In order to make it, he assiduously researched a good deal of relevant reference materials, comparing to many works he had seen before. It is reasonable that his important relationship with Chang Chao(張照: 1691-1745) and Wang Hui (왕휘: 1632-1717) made him cherish knowledge of traditional painting without any literate background. Given other catalogues published in the Ch`ing dynasty, the Mo-yu¨an hui-kuan shows a similar method in the light of entries; material, size, inscriptions, colophons, and seals. Despite its similar organization it has more meaningful information accounted in detail in this paper. All paintings and calligraphic works in this voluminous catalogue are chronologically arranged dating from the Chin till the Ming dynasties. Section three, chu¨an 3 includes the artists and their works through the centuries. Since he considered a number of paintings recorded in this section mostly were authentic, An Ch´i briefly described the technique, painting style, and subject matters rather than dealing with connoisseurship. He often referred to some critical comments on other connoisseurs` mistaken remarks or citations. He, however, avoided making any additional statement about works he had never examined. As opposed to chu¨an 3, chu¨an 4 is merely dedicated to album leaves(帖) that contained works by several artists under the same title. Although An Ch´i´s commentary is not much longer than that in chu¨an 3, it is meaningful to note that he attempted to authenticate some examples handed down as the so-called genuine works by the earlier connoisseurs. In the case of re-attribution, he supported his suggestion with definite evidence. For example, Yen ching-t´u (煙景圖) was attributed to Kuo Hsi (郭熙: 1020-1074) by Tung Ch´i-ch´ang, An Ch´i carefully corrected Tung´s error after he found out Yang Shih-hsien´s (楊士賢: 12th ct.) signature on the painting. The astute comments found in such writings reveal his startling insight into connoisseurship. Other instances quoted in this paper present the vast information of the individual artists and their works as well as documentary sources of those still extant or now lost. It means many famous art works passed through his hands. His catalogue, Mo-yu¨an hui-kuan shows how a Korean-Chinese connoisseur was struggling to solve problems concerning date, removed seals, limited texts, and forgeries. His comprehensive research provided a standard from which connoisseurship in the later Ch´ing period could develop. Thus, it would not be exaggerated to say that An Ch´i occupied a key place as an eminent connoisseur-collector in the northern Yangze area of the eighteenth century China.

Anonymity-Based Authenticated Key Agreement with Full Binding Property

황정연,엄성욱,장구영,이필중,양대헌 한국통신학회 2016 Journal of communications and networks Vol.18 No.2

In this paper, we consider some aspects of binding propertiesthat bind an anonymous user with messages. According towhether all the messages or some part of the messages are boundwith an anonymous user, the protocol is said to satisfy the full bindingproperty or the partial binding property, respectively. We proposemethods to combine binding properties and anonymity-basedauthenticated key agreement protocols. Our protocol with the fullbinding property guarantees that while no participant’s identity isrevealed, a participant completes a key agreement protocol con-firming that all the received messages came from the other participant. Our main idea is to use an anonymous signature scheme witha signer-controlled yet partially enforced linkability. Our protocolscan be modified to provide additional properties, such as revocableanonymity. We formally prove that the constructed protocols aresecure.

In this paper, we intend to make fringe-field switching (FFS) mode cell by the ion beam (IB) alignment method on the a-C:H thin film, to analyze electro-optical characteristics in this cell. We studied on the suitable inorganic thin film for fringe-field switching (FFS) cell and the aligning capabilities of nematic liquid crystal (NLC) using the alignment material of a-C:H thin film as working gas at 30 W rf bias condition. A high pretilt angle of about 5 $^{\circ}C$ by ion beam (IB) exposure on the a-C:H thin film surface was measured. Consequently, the high pretilt angle and the good thermal stability of LC alignment by the IB alignment method on the a-C:H thin film surface as working gas at 30 W rf bias condition can be achieved. An excellent voltage-transmittance (V -T) and response time curve of the IE-aligned FFS-LCD was observed with oblique IB exposure on the a-C:H thin films. Also, AC V-T hysteresis characteristics of the IB-aligned FFS-LCD with IE exposure on the a-C:H thin films is almost the same as that of the rubbing-aligned FFS cell on a polyimide (PI) surface.

Ν-(phenyl)maleimide 표면에 UVLPH 광중합법을 이용한 광배향 TN 셀의 전기광학특성에 관한 연구

황정연,김준영,김태호,서대식,김영식 한국전기전자재료학회 2002 전기전자재료학회논문지 Vol.15 No.8

Electro-optical (EO) performances for the twisted-nematic (TN)-liquid crystal display (LCD) photoaligned with linearly polarized UV exposure on the poly[4- (fluorocinnamate) phenylmaleimide](PFCPMI) surfaces using a new photodimerization method were investigated. For a new UVLPH (UV linearly polarized during heating) photodimerization method, the photopolymer layers were exposed by linearly polarized UV dichroic polarizer without a specific UV filter during heating at $150^{\circ}C$. The Voltage-transmittance (V-T) curve without backflow bounce in the photoaligned TN-LCD with UV exposure on the PFCPMI surface for 10 min using the UVLPH photodimerization method was observed. For response time measurement, the transmittance characteristics of the photoaligned TN-LCD using the UVLPH photodimerization method on the photopolymer surface was better than that of the photoaligned TN-LCD using the UVLP photodimerization method under a room temperature.

콜레스테롤 산화 생성물 7-Ketocholesterol에 의한 세포자멸사에 미치는 Extracellular Signal-Regulated Kinase 억제의 효과

황정연,이선화,한정호,김두응,이정수 대한신경과학회 2011 대한신경과학회지 Vol.29 No.4

Background: Defects in mitochondrial function have been shown to participate in the induction of neuronal cell injury. The extracellular-signal-regulated kinase (ERK) signaling pathway plays a crucial role in almost all cell functions,including proliferation, differentiation, survival, and death. However, the effect of ERK inhibition on oxysterol-induced apoptosis remains uncertain. Methods: This study assessed the effect of ERK inhibition on the apoptotic effect of 7-ketocholesterol. Results: Treatment with 7-ketocholesterol increased phosphorylated-ERK1/2 levels in differentiated PC12 cells, while the total amount of ERK was not altered. 7-Ketocholesterol decreased Bid and Bcl-2 levels, increased Bax and p53 levels,and promoted cytochrome c release, which elicits the activation of caspases (-8, -9, and -3), nuclear damage, and cell death. ERK and farnesyltransferase inhibitors inhibited the 7-ketocholesterol-induced phosphorylation of ERK1/2,activation of apoptosis-related proteins, and cell death in PC12 cells. Conclusions: The ERK and farnesyltransferase inhibitors, which did not exhibit toxicity, may inhibit the 7-ketocholesterol toxicity on differentiated PC12 cells by suppressing the activation of the caspase-8-dependent pathway as well as activation of the mitochondria-mediated cell-death pathway, leading to the activation of caspases. The inhibition of ERK may confer a beneficial protective effect against the neuronal cell injury induced by cholesterol oxidation products.
