  • This paper focuses on the dating and provenance of two paintings, Climbing the hill and View from St. John's Fort by the prominent Singaporean artist Liu Kang (1911-2004). Climbing the hill, from the National Gallery Singapore collection, was believed to have been created in 1937, based on the date painted by the artist. However, a non-invasive examination unveiled evidence of an underlying paint scheme and a mysterious date, 1948 or 1949. These findings prompted a comprehensive technical study of the artwork in conjunction with comparative analyses of View from St. John's Fort (1948), from the Liu family collection. The latter artwork is considered to be depicting the same subject matter. The investigation was carried out with UVF, NIR, IRFC, XRR, digital microscopy, PLM and SEM-EDS to elucidate the materials and technique of both artworks and find characteristic patterns that could indicate a relationship between both paintings and assist in correctly dating Climbing the hill. The technical analyses were supplemented with the historical information derived from the Liu family archives. The results showed that Climbing the hill was created in 1948 or 1949 on top of an earlier composition painted in Shanghai between 1933 and 1937. As for the companion View from St. John's Fort from 1948, the artist reused an earlier painting created in France in 1931. The analytical methods suggested that Liu Kang used almost identical pigment mixtures for creating new artworks. However, their painting technique demonstrates some differences. Overall, this study contributes to the understanding of Liu Kang's painting materials and his working practice.

  • The attitude of observer in the painting of history is to exclude a prejudice and a subjective view of an artist and to introduce a photograph, which is a record of objectivity, in the process of painting. Its ultimate intent is to redescribe the fact of an event's image intactly without any prejudice and to represent the event as a proven evidence that it was. The representation of history based on fact had already been conceived in imagination of renowned artists such as Francisco Goya or $Th{\acute{e}}odore$ $G{\acute{e}}ricault$ even before cameras were invented. What they portrayed was their own truth of reality which is gained through their observation, not a history that have corresponded to political ideologies, for all reliance on a limited tool of representation, painting. Furthermore, history was necessary for 19th century impressionism artists to be represented under proven fact in a neutral perspective excluding all subjective prejudice, not based on the representation with imagination. Edouard Manet in particular reconstited an instant moment on the basis of real proof of photograph without personal prejudice or opinion as if today's photojournalism. The catastrophic series by Andy Warhol and the photographic painting by Gerhard Richter show another role of painting in the realm of art, each of them implying information distortion and abuse by current media and intentional deformation toward history as Manet's painting of history. Today, the representation of an historical event that we experience in the era of the Internet and social networks having a great deal of information already came to be the exclusive property of the cutting edge mass media. Nevertheless, the attitude of observer which is realistic and contemplative in the realm of art is the crucial point in terms of artists' act as ever.

  • 본고에서는 최근의 전자기록 환경을 맞아 새롭게 조명 받고 있는 기록이 지닌 지식 정보 자원으로서의 의미를 기존의 연구성과 및 사례들을 기반으로 고찰하였다. 기록의 생산모태라 할 수 있는 조직의 운영방식 및 업무패턴의 변모에 따라 종래 비현용단계에서의 역사문화적 가치를 우선시하는 경향을 탈피하고, 조직 경영과 업무 수행에 실질적 이익을 주는 지식 정보 자원으로서의 가치 역시 중시되고 있음을 파악하고자 하였다. 이를 위해 2장에서는 최근의 업무환경 변화상을 살펴본 후, 기록이 지닌 증거로서의 속성뿐만 아니라 정보로서의 속성 역시 강조되고 있음을 고찰하였다. 이러한 논의를 기반으로 3장에서는 1980년대부터 서구 기록학계에서 논의되어 온 기록과 정보의 관계를 고찰한 후, 이어 최근의 업무환경에서 정보를 대체하는 개념인 지식과 기록의 상관관계와 함께 기록관리와 지식관리의 연계 필요성을 논의하였다. 그리고 4장에서는 호주 및 영국, 미국 사례를 통해 기록관리와 지식관리를 연계시키기 위한 최근의 기록학계 동향을 살펴본 후, 우리나라 공공기록관리 영역의 현황과 함께 지식 정보 자원으로서의 기록관리를 진작시키기 위한 제도적 개선방향을 세 가지 측면에서 제시하였다.

  • Nat Turner's rebellion in 1831 was considered pre Civil War South's most dreadful nightmare due to the merciless murder of white slave owner victims. The motive of vengeance has been emphasized as that of Turner's notorious black preacher religious fanaticism. However, the recent film, The Birth of a Nation (2016) directed by Nate Parker, utilized the identical title of a film (1915) directed by D. W. Griffith. Providing limited evidence, information about the rebellion in Thomas Gray's pamphlet The Confessions of Nat Turner (1831), was the only accessible historical source for the factual event of the slaves' rebellion. In addition, William Styron's The Confessions of Turner (1967), a fictionalized biography, also examined Turner's life in the harshness of slavery. Although these two texts deal with the personal level of Nat Turner's rage and religious enthusiasm, both provide only fractured parts of the motive of vengeance. Strikingly, Parker's film interrogates the ideology of "victims," as well as the hierarchical term of "confessions," with their different positions between whites and blacks. More specifically, Parker's film offers discursive fields of proslavery arguments regarding biblical interpretations in addition to external visualization of slaves' inner emotional lives. The film demonstrates how the institution of slavery allowed slaves to be exploited, beaten, raped, through interrogating the problematic image of the "contested hero" Nat Turner. In contrast to the traditional image of blacks' bloody rebellion, the film underlines the absurdity of certain Biblical misinterpretations. It furthermore implies how the 1915 film manipulated proslavery propaganda in America.

  • Dongje school (同濟學校), alternately Dongje medical school, is generally recognized as the first modern school for Korean medicine. However, there is very limited information concerning its establishment, duration period, governance, location, and contents for teaching. We found several points which are different from popular opinions through investigating news articles of those days and maps. Dongje school has established on June 1, 1906 and the time of its discontinuance is not clear. The school was founded with the cooperation of three former government officials of the Korean Empire, Eungse Lee (李應世), Piljoo Kang (姜弼周), and Dongho Cho (趙東浩) and many people donated fund for supporting Dongje school. However, there is no evidence of national or royal expenditures for operating the school. Dongje school has been established in 76-6, Seohak hill (西學峴), Yeogyeong-bang (餘慶坊), West county (西署), Seoul and moved to Naesum-si (內贍寺) located in Bongsangsi front village (奉常寺前門洞), Indal-bang (仁達坊), West county, at September 1906. The curriculum of the school comprehends several disciplines including literature in Korean and Chinese, mathematics, foreign language, physics, and Western medicine, as well as Korean medicine. Particularly at that time, they thought both of women and men. To elucidate the issue of the governance of Dongje school regarding the national or royal establishment, more information and extensive studies should be needed.

  • Objectives : An error was found in the recent standard by the World Health Organization (WHO) on the locations of the Upper arm Route of Lung Meridian (URLM) and its acupoints LU3 and LU4. This possible incorrect information is being taught throughout Korean medicine colleges nationwide, which follow WHO standards. Therefore, an investigation is required to sort out this discrepancy based on the evidence in historical documents. Methods : The location of WHO's URLM and LU3 and LU4 were compared with corresponding information in the classical literature. The anatomical structure mentioned in these classical documents was examined. Finally, an assessment was conducted on whether this structure is reflected in the WHO standards. Results : Classical literature prior to the early 20th century records the locations of the Lung Meridian and LU3 and LU4 of the upper arm to be in the artery on the medial aspect. This artery corresponds to the brachial artery. The location established by the WHO is on the anterolateral side of the upper arm, where no large arteries exist that can be found by haptic search or angiographically. The anterolateral side of the upper arm belongs to the Yang aspect, which does not coincide with the Yin aspect of Lung Meridian. Conclusions : The WHO's URLM and LU3-4 standards do not agree with the classical literature. The correct route must coincide with the brachial artery passing through the medial side of the humerus. The actual location of LU3-4 is on the medial aspect of the arm, just medial to the border of the biceps brachii muscle, on the brachial artery, 3-4 B-cun inferior to the anterior axillary fold.

  • Flooding has become an increasing event which is one of the major natural disasters responsible for direct economic damage in South Korea. Driven by climate change, precipitation extremes play significant role on the flood damage and its further increase is expected to exacerbate the socioeconomic impact in the country. However, the empirical evidence associating changes in precipitation extremes to the historical flood damage is limited. Thus, there is a need to assess the causal relationship between changes in precipitation extremes and flood damage, especially in agricultural region like Chungcheong region in South Korea. The spatial and temporal changes of precipitation extremes from 10 synoptic stations based on daily precipitation data were analyzed using the ClimPACT2 tool and Mann-Kendall test. The four precipitation extreme indices consisting of consecutive wet days (CWD), number of very heavy precipitation wet days (R30 mm), maximum 1-day precipitation amount (Rx1day), and simple daily precipitation intensity (SDII), which represent changes in intensity, frequency, and duration, respectively, and the time series data on flooded area and flood damage from 1985 to 2020 were used to investigate the causal relationship in the ARDL-ECM framework and pairwise Granger causality analysis. The trend results showed that majority of the precipitation indices indicated positive trends, however, CWD showed no significant changes. ARDL-ECM framework showed that there was a long-run relationship among the variables. Further analysis on the empirical results showed that flooded area and Rx1day have significant positive impacts on the flood damage in both short and long-runs while R30 mm only indicated significant positive impact in the short-run, both in the current period, which implies that an increase in flooded area, Rx1day, and R30 mm will cause an increase in the flood damage. The pairwise Granger analysis showed unidirectional causality from the flooded area, R30 mm, Rx1day, and SDII to flood damage. Thus, these precipitation indices could be useful as indicators of pluvial flood damage in Chungcheong region of South Korea.
