  • "The Collection of Yi Chungmugong" manuscript is a hand-written manuscript of the volume 1 consisting of the Collection, published in 1795 and it seems to have completed the contents of the book by correcting the first part of the book before print. The book adopted a form of Seonjangbon(線裝本) of Ochimanjeongbeop(五針眼訂法) and was urgently needed some measures to preserve because it has been much damaged by stains, loss and oxidation due to moisture on the bottom of it. In addition, a scientific investigation was applied to find out the features of the quality of paper and fiber used for the book, which would be reflected in the process of the preservation. The characteristics of paper were measurmented for size(cm), thickness(mm), weight(g), basis weight($g/m^2$), density($g/cm^3$), chain line and laid lines($3{\times}3cm$). The measurement showed that the characteristics of paper used in royal books published in the late Joseon Dynasty. For the paper-fiber of the book, C stain was used and the technique revealed that the book is made of bast fibre of paper mulberry and its binding strings are cotton. SEM-EDS analysis was performed to verify the existence of additives in paper. As a result of the analysis, The crystallized calcium was detected in addition to the main components carbon(C) and oxygen(O). This artifact is the unique final version of "The collection of Yi Chungmugong", which has considerable value in terms of academic research, besides it helps to understand how to print books of Joseon Dynasty. And it also has a very accurate information of when and where the book was made, which primarily could be resources to conserve and restore for other book heritage.

  • Population growth and the increase of energy consumption due to civilization caused global warming. Temperature on the Earth rose about $0.7^{\circ}C$ for the last 100 years, the rate is accelerated since 2000. Temperature is a factor, which determines physiological action, growth and development, survival, etc. of the plant together with light intensity and precipitation. Therefore, it is expected that global warming would affect broadly geographic distribution of the plant as well as structure and function ecosystem. In order to understand the effect of global warming on the ecosystem, a study about the effect of temperature rise on germination and growth in the plant is required necessarily. This study was carried out to investigate the effects of experimental warming on the germination and growth of two oak species(Quercus mongolica and Q. serrata) in temperature gradient chamber(TGC). This study was conducted in control, medium warming treatment($+1.7^{\circ}C$; Tm), and high warming treatment ($+3.2^{\circ}C$; Th) conditions. The final germination percentage, mean germination time and germination rate of two oak species increased by the warming treatment, and the increase in Q. serrata was higher than that in Q. mongolica. Root collar diameter, seedling height, leaf dry weight, stem dry weight, root dry weight, and total biomass were the highest in Tm treatment. Butthey were not significantly different in the Th treatment. In the Th treatment, Q. serrata had significantly higher H/D ratio, S/R ratio, and low root mass ratio (RMR) compared with control plot. Q. mongolica had lower RMR and higher S/R ratio in the Tm and Th treatments compared with control plot. Therefore, growth of Q. mongolica are expected to be more vulnerable to warming than that of Q. serrata. The main findings of this study, species-specific responses to experimental warming, could be applied to predict ecosystem changes from global warming. From the result of this study, we could deduce that temperature rise would increase germination of Q. serrata and Q. mongolica and consequently contribute to increase establishment rate in the early growth stage of the plants. But we have to consider diverse variables to understand properly the effects that global warming influences germination in natural condition. Treatment of global warming in the medium level increased the growth and the biomass of both Q. serrata and Q. mongolica. But the result of treatment in the high level showed different aspects. In particular, Q. mongolica, which grows in cooler zones of higher elevation on mountains or northward in latitude, responded more sensitively. Synthesized the results mentioned above, continuous global warming would function in stable establishment of both plants unfavorably. Compared the responses of both sample plants on temperature rise, Q. serrata increased germination rate more than Q. mongolica and Q. mongolica responded more sensitively than Q. serrata in biomass allocation with the increase of temperature. It was estimated that these results would due to a difference of microclimate originated from the spatial distribution of both plants.

  • The flowering seasons can be advanced due to climate change that would cause an abnormally warm winter. Such warm winter would increase the frequency of crop damages resulted from sudden occurrences of low temperature before and after the vegetative growth stages, e.g., the period from germination to flowering. The degree and pattern of freezing damage would differ by the development stage of each individual fruit tree even in an orchard. A critical temperature, e.g., killing temperature, has been used to predict freeze damage by low-temperature conditions under the assumption that such damage would be associated with the development stage of a fruit flower bud. However, it would be challenging to apply the critical temperature to a region where spatial variation in temperature would be considerably high. In the present study, a phenological model was used to estimate major bud development stages, which would be useful for prediction of regional risks for the freeze damages. We also derived a linear function to calculate a probabilistic freeze risk in spring, which can quantitatively evaluate the risk level based solely on forecasted weather data. We calculated the dates of freeze damage occurrences and spatial risk distribution according to main production areas by applying the spring freeze risk function to apple, peach, and pear crops in 2018. It was predicted that the most extensive low-temperature associated freeze damage could have occurred on April 8. It was also found that the risk function was useful to identify the main production areas where the greatest damage to a given crop could occur. These results suggest that the freezing damage associated with the occurrence of low-temperature events could decrease providing early warning for growers to respond abnormal weather conditions for their farm.

  • Recently, the international standardization of ISO in the field of Oriental Herbal Medicine has been progressing rapidly under the direction of China's promotion. China's intention to promote international standardization is to extend its influence to the world and beyond the domestic market. The Oriental medicine system in East Asia has similar roots in academic terms, but the medicines that can be supplied and received in each country are different and have developed independently. The international standardization of medicinal herbs is expected to function in a direction that weakens such differentiation and independence. From a commercial point of view, international standardization is no different from creating evaluation criteria for oriental medicinal products, and it is expected that its potential impact on domestic and overseas markets and producers will be large. In particular, the international standardization centered on China can lead to favorable evaluation criteria for China, which may further negatively affect the market competitiveness of domestic raw materials, which have been pushed back by Chinese manufacturers. If the domestic production base is weakened, not only will the farmers suffer but the supply and demand of raw materials will also be manipulated, safety management control will be reduced, and the development of oriental herbal products using domestic raw materials will be hurt. Therefore, in the promotion of international standardization, it is necessary not only to reflect the value of Korean herbal medicine but also to provide strategic responses to protect the domestic production base. However, in the case of recent initiatives, there is no precedent in analyzing influence on the production partners and the related industries. In addition, there are few related papers and reports on the subject, so the publicity process has not been done sufficiently. In response to this, this study will examine the countermeasures against the international standardization of herbal medicines through reviewing its present status and evaluating the agenda of the Korean initiative.

  • Cloud computing is a computing paradigm in which users can utilize computing resources in a pay-as-you-go manner. In a cloud system, resources can be dynamically scaled up and down to the user's on-demand so that the total cost of ownership can be reduced. The Modeling and Simulation (M&S) technology is a renowned simulation-based method to obtain engineering analysis and results through CAE software without actual experimental action. In general, M&S technology is utilized in Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), Multibody dynamics (MBD), and optimization fields. The work procedure through M&S is divided into pre-processing, analysis, and post-processing steps. The pre/post-processing are GPU-intensive job that consists of 3D modeling jobs via CAE software, whereas analysis is CPU or GPU intensive. Because a general-purpose desktop needs plenty of time to analyze complicated 3D models, CAE software requires a high-end CPU and GPU-based workstation that can work fluently. In other words, for executing M&S, it is absolutely required to utilize high-performance computing resources. To mitigate the cost issue from equipping such tremendous computing resources, we propose HEMOS-Cloud service, an integrated cloud and cluster computing environment. The HEMOS-Cloud service provides CAE software and computing resources to users who want to experience M&S in business sectors or academics. In this paper, the economic ripple effect of HEMOS-Cloud service was analyzed by using industry-related analysis. The estimated results of using the experts-guided coefficients are the production inducement effect of KRW 7.4 billion, the value-added effect of KRW 4.1 billion, and the employment-inducing effect of 50 persons per KRW 1 billion.

Cases and Significance of Inscriptions with Homophonic yet Misspelled Words on Buncheong Ware from the Early Joseon Dynasty: Buncheong Bowl with Inscription of "Naeja" ('내자(內子)'명(銘)으로 본 조선 전기 분청사기의 동음오자(同音誤字) 명문 사례와 의의)

  • The inscription found on buncheong ware (粉靑沙器, grayish-blue-powdered celadon) provides information on the bowl today, but in the past served as a device for controlling tributary payments (貢納) and the movement of government property (官物). The inscription had to be written or engraved clearly so that it could be recognizable to officials in charge of managing bowls. Such inscriptions offer important clues for contemporary research on buncheong ware. Buncheong Bowl with Stamped Design and Inscription of "Naeja" (內子) (bon 13808) in the collection of the National Museum of Korea bears a distinct inscription compared to other buncheong ware. Commonly, the inscription on buncheong indicated the name of the government office (官司名) to which the vessel belonged or the name of the place (地名) where the vessel was produced. However, the inscription "Naeja" on the buncheong bowl at the National Museum of Korea has no corresponding government office. "Naeja" is in fact a misspelling of Naeja (內資), meaning this bowl belonged to the Naejasi (內資寺, Royal Bureau of Procurement). Although "Naeja" (內子) was a misspelling of the intended Naeja (內資), it was still understood as a reference to the Naejasi since they were homophonic. Recently, buncheong ware with misspelled yet homophonous inscriptions have begun to be excavated in downtown Seoul. Examples including "Naeja" (內子) instead of Naeja (內資) and "Insu" (仁守) instead of Insu (仁壽) have been unearthed from historical sites in Seoul that functioned as consumption sites, meaning they were in fact circulated as government property despite the misspellings (whether accidental or the outcome of ignorance). Such misspelled yet homophonous inscriptions are characterized by the use of simple characters and a few sloppy strokes. Like other buncheong ware bearing the inscriptions of government office names, the bowls with the inscriptions of "Naeja" (內子) and "Insu" (仁守) were discovered at historical sites in Seoul. These misspelled homophonous inscriptions reveal that errors occurred during the process of engraving inscriptions on buncheong ware produced as a tributary payment during the early Joseon Dynasty and that buncheong ware with such errors were still distributed.

The Problem of the Interpretation of the Fû Hexagram[復卦] based on Zhu Xi[朱熹]'s Theory of Psychology (주희(朱熹) 심성론(心性論)을 중심으로 본 복괘(復卦) 해석의 문제)

  • This paper is a reflective study of contemporary Korean scholars' claims that they criticize the explanation of Zhu Xi(朱熹, 1130-1200)'s psychology in which he explains that the 24th Hexagram of $F{\hat{u}}$[復卦] shows the state that the mind has not happened yet[未發]. Zhu Xi explains the 24th Hexagram of $F{\hat{u}}$[復卦] with the theory of no mind yet[未發說]. Several scholars in modern Korea, however, raise the question of whether "thoughtless[思慮未萌] but being not dark to perception[知覺不昧]" of the 24th Hexagram of $F{\hat{u}}$ is enough to explain the state of no mind yet. And they think that "thoughtless[思慮未萌]" is appropriate to explain the state in which the mind has not yet occurred, but it is not to "being not dark to perception". In this study, we would like to show that Zhu Xi's interpretation of the 24th Hexagram of $F{\hat{u}}$[復卦] fully explains the fact that "thoughtless[思慮未萌] but being not dark to perception[知覺不昧]" explain the theory of no mind yet[未發說]. Zhu Xi's 'the theory of no mind yet[未發說]' is divided into two periods, a period of 'old theory on $zh{\bar{o}}ngh{\acute{e}}$[中和舊說]' and a period of 'new theory on $zh{\bar{o}}ngh{\acute{e}}$[中和新說]'. He develops 'the theory of no mind yet[未發說]' on the basis of 'the theory that nature is body and mind is action[性體心用說]' during the period of old theory, and develops the theory[未發說] based on 'the theory that mind controls nature and feelings[心統性情說]' during the new theory. Between the two periods, the status of the mind changes from "the mind has already happened[已發]" to "through which the mind has not yet arisen and the mind has already risen[未發已發]". And its role also changes from 'what nature is happened' to 'presiding on nature and emotion.' This change affects the interpretation of the idea that the mind has not yet happened, that thoughts have not budged yet[思慮未萌], perception is not dark[知覺不昧].

  • This study aims to look into weapons names mentioned in "Unhae", a book of traditional martial arts annotated into Korean. Comprehensive conclusions drawn from this are as follow. First, the annotated martial arts book is compiled to the order of Muyejaebo of year 1598, Muyejaebobunyuksokjib(A annotated attachment to Mooyejebo) of year 1610, Moojesinbo of year 1759, and Muyedobotongji of year 1790. Second, in the martial arts book are a total of 24 weapons with 4 types of spears, swords, bare hands & poles, and horseback weapons. Weapon names of ?Unhae? taken into detailed analysis, spears are 5 types of Jangchang (long spears), Jukjangchang (long spears made of bamboo), Keechang (flagged spears), Dgangpa (skewered spears), and Nangseon (forked spears). Swords are 10 types of Ssangsoodo (two-handed swords), Yedo (pointed swords), Waegum (Japanese swords), Waegumkyojun (Japanese battle swords), Jedokgum (Admiral's swords), Bongukgum (native swords), Ssanggum (coupled swords), Woldo (moon swords), Hyupdo (narrow swords), Deungpae (swords made of rattan). Bare hands & poles are 3 types of Gwonbeop (fists), 7070 Gonbang (clubs), and Pyeon-gon (flailed clubs). Horseback weapons are 6 types of flagged spears, MasangSsanggum (coupled horseback spears), MasangWoldo (horseback moon swords), MasangPyeon-gon (horseback flailed clubs), Kyukgoo (striking poles), and Masangjae (horse postures). Third, spears of the martial arts book, "Unhae" had the function as long weapons and were used for military drills of the infantry. Swords had the function as short weapons, and were used for military drills of the infantry. Bare hands & poles had the function as short weapons and were used for military drills of the infantry. Horseback weapons composed of short and long weapons were used for military drills of the cavalry. In addition to these, Kyukgoo (striking poles), and Masangjae (horse postures) were martial arts to which entertaining elements were added. Fourth, the difference in its compiling is that Mooyejebo and A annotated attachment to Mooyejebo place both Chinese characters and Korean annotation in the context together with introduction of weapons while Moojedobo Tongji explains weapons in Chinese and compiles a separate copy of Korean annotation that explains mainly postures in each lineage of martial arts for soldiers to acquire practical skills.

  • Hojil(虎叱) and Yangbanjeon(兩班傳) reveal the characteristic styles of Park Jiwon(朴趾源)'s writing, which is combining styles of unofficial history/biography(外傳) and allegory(寓言), and full of the senses of satire and humour which form another characteristc of his writing style or tone. This paper reexamines narrative styles, meaning structures and themes of these two works which combine the styles of unofficial history/biography and allegory, and researches methods and techniques of allegory and satire which presents the subversive and critical themes and thoughts of the author. In Hojil, combining of the two styles, the author constructs the narrative world and plot, manipulates allegoric figures to symbolize and present multilayered meaning, and criticize the decadence of confucian aristocracy [Sadaebu: 士大夫] and it's abuses. In Yangbanjeon by combining of two styles, the author weave a biography of Yangban(兩班) in general, which presents the attributes and historical position of the Yangban class. And by the nonsensical fictional event which caricatures crisis of the Yangban class, and tedious description of the manners and behaviors of the Yangban, the author and satires the snobbery of the Yangban and the absurdity of their classical privileges. As he did in Hojil, the author urges the self-examination of the reader raising a question about the position and the function or duty of the Yangban class in the changing world. And the various skills of satire together with the irony, paradox, parody and pun were used dexterously in above two works.

1970 UNESCO Convention on the Illicit Trafficking of Cultural Property and its Legal Implementations in the Republic of Korea (문화재 불법 거래 방지에 관한 1970년 유네스코 협약의 국내법적 이행 검토)

  • This year is the 50th anniversary of the adoption by UNESCO in 1970 of the Convention on the Means of Prohibiting and Preventing the Illicit Import, Export, and Transfer of Ownership of Cultural Property (the '1970 Convention'). Since its ratification of the 1970 Convention in 1983, the Republic of Korea has domestically implemented the Convention through its Cultural Heritage Protection Act, which was first enacted in 1962. This is a different form of implementation than is normally used for other UNESCO Conventions on cultural heritage, in that the Republic of Korea has recently adopted special acts to enforce the 2003 Convention for the Safeguarding of Intangible Cultural Heritage and the 1972 Convention concerning the Protection of the World Cultural and Natural Heritage. In addition, the 1970 Convention has been developed further through the introduction of new Operational Guidelines in 2015 for the concrete enforcement of the Convention, which has provided momentum for the Republic of Korea to analyze its current national legislation related to the 1970 Convention as well as consider its amendment in the future. Overall, the Cultural Heritage Protection Act of the Republic of Korea effectively reflects the duties of States Parties under the 1970 Convention. These include measures to introduce export certificates, prohibit the import of stolen cultural property, return other state parties' cultural property, and impose penalties or administrative sanctions in the event of any infringements. Indeed, the Republic of Korea's implementation of the 1970 Convention was introduced as an example of good practice at the Meeting of State Parties in 2019. However, changes in the illegal market for cultural property and development of relevant international law and measures imply that there still exists room for improvement concerning the legal implementation of the 1970 Convention at the national level. In particular, the Operational Guidelines recommend States Parties to adopt legal measures in two respects: detailed criteria for due diligence in assessing bona-fide purchasers, referring to the 1995 UNIDROIT Convention on Stolen or Illegally Exported Cultural Objects, and measures to address the emerging issue of illegal trade in cultural property on internet platforms. Amendment of the Cultural Heritage Protection Act and other relevant laws should be considered in order to duly reflect these issues. Taking that opportunity, concrete provisions to facilitate international cooperation in respect of the implementation of the 1970 Convention could be introduced as well. Such measures could be expected to strengthen the Republic of Korea's international legal cooperation to respond to the changing environment regarding illicit trafficking of cultural property and its restitution.
