Hue, value, and chroma are the fundamental colour components used in colour property research to identify colour in the digital media environment. In the Munsell colour system, which is based on the characteristics of visual perception, the basic properties are classified into hue, value, and chroma. The methods for recording these three properties can be divided into the colour appearance system and the colour mixing system: in the former, they are documented based on a colour chart that focuses on visual perception, and in the latter, accurate numerical records are kept without concern for discolouration. Colour terminology is crucial for conveying and expressing colours, and colours can be classified and defined according to the combination of hue, value, and chroma. With the development of various media, it has become possible to represent a range of colours previously unachievable, necessitating basic research into the characteristics of colour perception by further subdividing digital-oriented colour studies. In this study, we conducted psychophysical experiments to identify and analyse the categories of value and chroma needed to recognise each colour among the ten representative colours of the Munsell colour system, based on visual perception on a display. This study analyses the results of these experiments, defines their significance as foundational research data on colour perception characteristics, and suggests directions for future research.

Study on ${\ulcorner}$Bonchojeonghwa${\lrcorner}$, which is one of the most specialized medical books in Boncho(Herbal Medicines), has been done by comparing it with some other medical books published in the Chosun dynasty. Though there was not meaningful result on e names of Korean medicine by this study and more study should follow in the future, from medicines recorded in ${\ulcorner}$Inbu (a chapter of medical ingredients from human body)${\lrcorner}$, we can reach on some results as follows by comparing in names of Korean medicines, their medical components, relevant explanations and etc. 1. Though it is difficult to know the author and the published year due to absence of the preface and epilogue, the publication is presumed to date from mid-l7th century, from the facts that Muheeong's ${\ulcorner}$Shinnongbonchokyongso${\lrcorner}$ is in the ${\ulcorner}$Bonchojeonghwa${\lrcorner}$'s reference list, and that there is not Hangul expression in the names of medicines nor the Ching dynasty’s books as a reference. 2. As a result of studying on the names of medicines recorded in ${\ulcorner}$Inbu${\lrcorner}$ of the Chosun dynasty's famous medical books, before ${\ulcorner}$ Bonchojeonghwa${\lrcorner}$, 19 medicines in ${\ulcorner}$Hyangyakjipsungbang${\lrcorner}$, 25 in ${\ulcorner}$Donguibogam${\lrcorner}$, and after ${\ulcorner}$Bonchojeonghwa${\lrcorner}$, 6 in ${\ulcorner}$Uimumbogam${\lrcorner}$, 4 in ${\ulcorner}$Kwangjebikup${\lrcorner}$, 11 in ${\ulcorner}$Bangyakhappyon${\lrcorner}$. And there are 37 medicines which are unique, ${\ulcorner}$Bonchojeonghwa${\lrcorner}$ has 31, the biggest records among them. 3. As a result of studying on the names of medicines recorded in 「Inbu」 of the ${\ulcorner}$Bonchojeonghwa${\lrcorner}$ and ${\ulcorner}$ Donguibogam${\lrcorner}$, 22 medicines were recorded in the both books, 9 were only recorded in ${\ulcorner}$Bonchojeonghwa${\lrcorner}$ and 3 were only recorded in ${\ulcorner}$Donguibogam${\lrcorner}$. 3 out of the total 37 medicines recorded in ${\ulcorner}$Inbu${\lrcorner}$ are only recorded in ${\ulcorner}$Hangyakjipsungbang${\lrcorner}$, and more study on this is needed. 4. From the contents recorded in ${\ulcorner}$Bonchojeonghwa${\lrcorner}$ and ${\ulcorner}$Donguibogam${\lrcorner}$, Benchojeonghwa is more in detail than Donguibogam. Thus, it was specialized in Boncho (Herbal Medicines) enough to be compared with general medical books, and played a good role in leading medical science's specialization. 5. Late Chosun dynasty's medical study on Boncho (Herbal Medicines) just like ${\ulcorner}$Bonchojeonghwa${\lrcorner}$ didn't lead to an active development of knowledge communication due to Confucian ethics. This limitation created the trend relying on general medical books or Yaksungga (songs of memorizing Boncho information) for Boncho information, but Boncho information of late Chosun dynasty became more in detail. That is, while Bokhapbang, combination of various medicines, were developed in China, Danmibang, single medicine but different intensity, were developed in Chosun. And thus, even though the kinds of medicines became smaller, but its contents became rather rich. 5. The medicines recorded in ${\ulcorner}$Bonchojeonghwa${\lrcorner}$ and ${\ulcorner}$Donguibogam${\lrcorner}$ are, from the view point of today, unclean or rather uncomfortable to use. Out those medicines, Bunchung, Hwasijangsanginkol, Hongyon, Gonidoogun, Inkondang had been used for a very long time and which proves their medical efficacy, and it is a great pity that they can’t be tried today due to the limitation by modern ethics.

Given that the concept of reproducing landscape is similar to that of recording historical sights, places can become special space where memories are archived through meaningful activities. Therefore, place and landscape are the important concepts for understanding the Home of Roh Moo-hyun. This research was initiated when Roh Moo-hyun Foundation's decided to return the Home of Roh Moo-hyun to the public. A research report was published as the first result of this initiative. Then an archive book was recently published based on the first research report. The research report was about philosophical and aesthetic meanings and contents, the layers of accumulated memories, the records based on the accumulated memories, and the attributes of the place, and the possibility of archiving, whereas the purpose of the archive book is to restore and to curate the original meaning of the Home of Roh Moo hyun through cultural events. There are 'three memories' of layers in the Home of Roh Moo-hyun. The first memory is about 'life and dreams' that President Roh Moo-hyun dreamed about after his retirement to the hometown. The second memory is about 'the loss of time' for 10 years of time after the decrease of the President Roh Moo-hyun. The third memory is 'the memory of citizens', which started with the public opening of the Home of Roh Moo-hyun. 'Low Roof House of President Roh Moo-hyun' is the archive book that comprises the three memories which are accumulated in the home of Roh Moo-hyun and 'record language' full of meanings.

Korea has a high standard of IT environment to serve exhibit programs through the web with internet propagation and IT technology. However, the web exhibition of public institutions not only seem to introduce off-line exhibitions but also not to invigorate. It is caused by the lack of awareness, the cost of system installation and the lack of professional manpower. In this situation, OMEKA could suggest practical solutions to archives where need their own exhibition through the web. Especially, it would helpful for small record management organizations which are not enough budget and personal. OMEKA is an open source software program for digital collection and contents management. It has an affinity with users unlike traditional archives service programs. It also has been variously used by libraries, museums and schools because of exceptional exhibit functions. In this article, we introduce to the installation of a practical use about OMEKA. Regarding to OMEKA features, we consider it to raise exhibit effects. OMEKA would reduce the cost related to plans of exhibitions because it could display various contents and programs which reflecting characteristics of institutions. In addition, the availability of installation and widespread technological environment would lessen burden of public institutions. Using OMEKA, they would improve service level of public institutions and, make users satisfy. Therefore, they can change the social recognition of public institutions. OMEKA can contribute to various exercises of public records. It is not just the stereotypical system but, serves exhibition and collections with the strategy which each public institution would like to display. After all, it not only to connect to users with producers but also to improve the public image of institutions positively. Then, OMEKA would bring the great result through this interaction between public institutions and users.

Purpose: Normal education operation was difficult in the national disaster situation of Coronavirus Infection-19. Non-face-to-face education can be an alternative to face to face education, but it is not easy to provide the same level of education. In this study, the professor of disaster management field will identify problems that can occur in the overall operation and progress of non-face-to-face education and seek ways to improve non-face-to-face education. Method: Non-face-to-face real-time education was largely categorized into pre-class, in-class, post-class, and evaluation, and case studies were conducted through the professor's case studies. Result&Conclusion: The results of the survey are as follows: First, pre-class, it was worth considering providing a non-face-to-face educational place for professors, and the need for prior education on non-face-to-face educational equipment and systems was required. In addition, it seems necessary to make sure that education is operated smoothly by giving enough notice on classes and to make efforts to develop non-face-to-face education programs for practical class. Second, communication between professor and learner, and among learners can be an important factor in non-face-to-face mid classes. To this end, it is necessary to actively utilize debate-type classes to lead learners to participate in education and enhance the educational effect through constant interaction. Third, non-face-to-face post classes, policies on the protection of privacy due to video records should be prepared to protect the privacy of professors in advance, and copyright infringement on educational materials should also be considered. In addition, it is necessary to devise various methods for fair and objective evaluation. According to the results of the interview, in the contents, which are components of non-face-to-face education, non-face-to-face education requires detailed plans on the number of students, contents, and curriculum suitable for non-face-to-face education from the design of the education. In the system, it is necessary to give the professor enough time to fully learn and familiarize with the function of the program through pre-education on the program before the professor gives non-face-to-face classes, and to operate the helpdesk, which can thoroughly check the pre-examination before non-face-to-face education and quickly resolve the problem in case of a problem.

Seojangdaeyajodo is a drawing of military night training on February 12th (lunar leap month), 1795. Focusing on the Seojangdaeyajodo, the characteristics and of the costumes worn by various types of officials were examined. There were 34 officials located near King Jeongjo in and around Seojangdae, with 27 Dangsanggwan and 7 Danghagwan. They wore three types of costumes, including armor, yungbok, and military uniforms. All of the twelve armor wearers and the five officials wearing yungbok were dangsanggwan, and the military uniform wearers included eleven dangsanggwan and six danghagwan. For the shape of the armor, the armor relics of General Yeoban, suitable for riding horses, and the armor painting of Muyedobotongji were referenced, and the composition of the armor was based on practicality. The armor consists of a helmet, a suit of armor, a neck guard, armpit guards, arm guards, and a crotch guard. The color of the armor was red and green, which are the most frequently used colors in Seojangdaeyajodo. The composition of yungbok was jurip, navy cheollik, red gwangdahoe, socks made of leather, and suhwaja. The composition of the military uniform was a lined jeolrip, dongdari, jeonbok, yodae, jeondae, and suhwaja. There were differences in the fabrics used in dangsanggwan and danghagwan military uniforms. Dangsanggwan used fabric with depictions of clouds and jewels, and danghagwan used unpatterned fabric. Moreover, jade, gold, and silver were used for detailed ornamental materials in dangsanggwan. The weapons included bows and a bow case, a sword, a rattan stick, wrist straps, and a ggakji. In the records of the King Jeongjo period, various colored heopsu were mentioned; the colors of the dongdari and jeonbok of dangsanggwan and danghagwan were referenced in various colors. It was presented as an illustration of costumes that could be used to produce objects accurately reflecting the above historical results. The basic principle of the illustration was to present the modeling standards for 3D content production. Samples of form, color, and material of the corresponding times and statuses were presented. The front, the side, and the back of each costume and its accessories were presented, and the colors were presented in RGB and CMYK.

In the history of Korean literature, evaluations on 『Jirisan』 (Lee Byeong-ju) are bisected. Some evaluate it as a novel of authentic records which reproduces the history before and after the emancipation objectively while others say it takes advantage of anti-communistic ideology. This study analyzes that difference is resulted not from the distinction of perspectives but from cracks in the text. This is associated with the process of 『Jirisan』's publication. 『Jirisan』 was published serially in 『Sedae』 from 1972, and then, part of the manuscript was published in 1978 and the whole edition published in a series came to be republished in 1981. After that, in 1981 and 1985, part of the follow-up story was printed on the magazine, and then, with the memoirs of those two years as materials, the sixth and seventh volumes were again published through 'revision'. In other words, the publication of 『Jirisan』 is divided into that of the edition published in a series and that of the edition published in 1985 including the contents of revision. The theme of the work, 『Jirisan』 differs according to the point of its completion you may think of. This researcher pays attention to the difference of perspectives between the contents up to the fifth volume and those of the sixth and seventh volumes. Particularly, his evaluation on 'partisans' seems to have changed. In the edition published in a series, he extended 'partisans' into the independence movement in the Japanese colonial era under the Revitalizing Reforms system and adopted the representation of 'partisans' three-dimensionally whereas in the sixth and seventh volumes, he reproduced 'partisans' as beings that were the 'doctrinaire' and 'vicious' 'Reds' and had to be punished. In brief, with 『Jirisan』, he represented 'partisans' in the background of history before and after the emancipation and segmented the discourse, representation and ideology of the Cold War system, but in the process of revision, he stitched up 'partisans' as beings that were evil and losers. Consequently, with 『Jirisan』, he revealed the process of division and contention that proceeded around anti-communism/capitalism within the abyss of the 1970's to 80's and reproduced 'partisans' as beings that were either 'hostile (the Reds)' or 'unknown (losers)

Youngsan is generally known as Pansori Danga(短歌). However, the contents of 'Yeongsan' in 『Songnamjabji』 are different. In 『Songnamjabji』, Cho Jaesam explained the contents related to 'Youngsan' using three kinds of poems: Shin Kwangsoo's poem, Baegho Imje's poem, Kim Myeongwon's poem. First, 'Ujo Youngsan' appears in Shin Kwangsoo's poem. Shin Kwangsoo wrote the (1750) when Yoo Jinhan's 『Manhwajib(晩華集)』(1754) was published. It is difficult to see the 'Ujo Youngsan', which appears in Shin Kwangsoo's poem written in a time when Pansori was not widely known, as the Pansori Danga. Second, Jo Jaesam called the music in Baegho Imje's poem 'Youngsan Dodeueum'. In 'Youngsan Dodeueum', flute and 'Dodeuli rhythm' were used. This fact is connected with , an instrumental music. , also a Buddhist term, continued to be used in the palace as well as among the people. Third, Cho Jaesam introduced Kim Myeongwon's poem in 'Yeongsan' part and called it 'Taryeong.' At that time, the term 'Taryeong' referred to both Pansori and Jeongga(正歌). Later, in the 19th century, 'Youngsan' was recorded as a term for the Danga to loosen the neck before Pansori began in earnest. In other words, the early 'Yeongsan' recorded in 『Songnamjabji』 was a Buddhist term, referring to the music of the upper class Seonbi, such as , Gasa(歌詞) and Sijo(時調). In 1855, when 『Songnamjabji』 was written, 'Youngsan' was used as a term used to refer to both Changbu-Music and Gagaek(歌客)-Music, mixed with the term 'Taryeong'. And as Pansori became popular, the term 'Taryeong' came to be called 'Pansori' and 'Youngsan' was used to refer to Pansori Danga. Therefore, all the records of 'Youngsan' should not be interpreted as Pansori Danga. This situation is closely related to religious and social change. The policy of worshipping Confucianism and suppressing Buddhism rejected the term 'Youngsan' which had a Buddhist meaning. In the middle of Joseon Dynasty, when Buddhism was suppressed, 'Youngsan' and 'Taryeong' were mixed. As Buddhism regrown in the late Joseon Dynasty, with the advent of Pansori, the term 'Youngsan' seems to be newly resettled in the sense of Danga. Pansori appeared in the 19th century and 'Yeongsan' was used as a Danga. And the reason should be regarded as this social and religious change.

The purpose of this study was to investigate the changes of taste components in the boiled beef brisket soup stock and shank soup stock by varying pretreatment, boiling temperature and time. Free amino acids and nucleotides color and sensory evaluation in each samples were analyzed. The results were obtained as follows : 1. The amount of free amino acids in the brisket soup stock pretreated by soaking and blanching showed a tendency to increase in proportion to boiling time. The amount of glutamic acid in the brisket soup stock was much in order of soaking > blanching > roasting pretreatment. While the amount of glutamic acid in the boiled soup stock samples pretreated by soaking and blanching was much more at low temperature than at high temperature, the glutamic acid contents in the boiled soup stock pretreated by roasting were large at high temperature. The amount of glutamic acid in pretreated by soaked soup stock showed the highest and recorded 8.73 mg% at 6 hour-low temperature-boiling. 2. The amount of free amino acids in the shank soup stock did not show any regular tendency and had few changes in quantity by the methods of pretreatment. Each amount of glutamic acid in the shank soup stock pretreated by soaking and blanching was the highest, when boiled for 3 hours at high temperature. The samples pretreated by roasting showed the highest record 2.49 mg%, when boiled for 6 hours at high temperature, but could not recognize any regular tendency in the case of boiling at low temperature. 3. The amount of nucleotides in the brisket soup stock generally showed increase in proportion to boiling time. The amount of 5'-IMP extracted from the brisket soup stock was much in order of blanching > soaking > roaking pretreatment, but few differences between blanching and soaking soup stock samples. The amount of 5'-IMP extracted from soup stock samples pretreated by soaking and blanching was high at low-boiling and by roasting at high-boiling. Each amount of 5'-IMP extracted from soup stocks pretreated by soaking(BSL) and blanching(BBL) was the highest at 6 hour-low-boiling(37.06 mg%), and 5 hours(38.37 mg%) respectively. The amount of 5'in the soup stock pretreated by roasting(BRH) showed the highest records at 6 hour-high-boiling(10.85 mg%). 4. The amount of 5'-IMP extracted from the shank soup stock preteated by soaking and blanching showed a tendency to decrease after 3 hours boiling irrelative of boiling temperature. The amount of 5'in the shank soup stock was much in order of soaking > blanching > roasting pretreatment and showed high at the boiling of high temperature. In the sample pretreated by roasting it showed the highst records when boiled for 6 hours at high temperature(1.55 mg%). 5. The L Value of the brisket soup stock pretreared by roasting at high temperature(BRH) was the lowest and the b value of it was the highest of all the brisket samples boiled for 6 hours. No differences were found in the Value of L, a, and b in shank soup stock by the methods of pretreatment and boiling temperature. 6. The sensory scores in color and flavor of the brisket soup stock showd that BRH was higher than the other samples, and the preference in taste and overall was the highest in BSH while it was the lowest in BRH. The preference in the all sensory characteristics of SSH was higher than any other shank soup stock, but did not show any significant difference statistically.

In the development of technologies, the exhibition industry has received much attention from governments and companies as an important way of marketing activities. Also, the exhibitors have considered the exhibition as new channels of marketing activities. However, the growing size of exhibitions for net square feet and the number of visitors naturally creates the competitive environment for them. Therefore, to make use of the effective marketing tools in these environments, they have planned and implemented many promotion technics. Especially, through smart environment which makes them provide real-time information for visitors, they can implement various kinds of promotion. However, promotions ignoring visitors' various needs and preferences can lose the original purposes and functions of them. That is, as indiscriminate promotions make visitors feel like spam, they can't achieve their purposes. Therefore, they need an approach using STP strategy which segments visitors through right evidences (Segmentation), selects the target visitors (Targeting), and give proper services to them (Positioning). For using STP Strategy in the smart exhibition environment, we consider these characteristics of it. First, an exhibition is defined as market events of a specific duration, which are held at intervals. According to this, exhibitors who plan some promotions should different events and promotions in each exhibition. Therefore, when they adopt traditional STP strategies, a system can provide services using insufficient information and of existing visitors, and should guarantee the performance of it. Second, to segment automatically, cluster analysis which is generally used as data mining technology can be adopted. In the smart exhibition environment, information of visitors can be acquired in real-time. At the same time, services using this information should be also provided in real-time. However, many clustering algorithms have scalability problem which they hardly work on a large database and require for domain knowledge to determine input parameters. Therefore, through selecting a suitable methodology and fitting, it should provide real-time services. Finally, it is needed to make use of data in the smart exhibition environment. As there are useful data such as booth visit records and participation records for events, the STP strategy for the smart exhibition is based on not only demographical segmentation but also behavioral segmentation. Therefore, in this study, we analyze a case of the promotion methodology which exhibitors can provide a differentiated service to segmented visitors in the smart exhibition environment. First, considering characteristics of the smart exhibition environment, we draw evidences of segmentation and fit the clustering methodology for providing real-time services. There are many studies for classify visitors, but we adopt a segmentation methodology based on visitors' behavioral traits. Through the direct observation, Veron and Levasseur classify visitors into four groups to liken visitors' traits to animals (Butterfly, fish, grasshopper, and ant). Especially, because variables of their classification like the number of visits and the average time of a visit can estimate in the smart exhibition environment, it can provide theoretical and practical background for our system. Next, we construct a pilot system which automatically selects suitable visitors along the objectives of promotions and instantly provide promotion messages to them. That is, based on the segmentation of our methodology, our system automatically selects suitable visitors along the characteristics of promotions. We adopt this system to real exhibition environment, and analyze data from results of adaptation. As a result, as we classify visitors into four types through their behavioral pattern in the exhibition, we provide some insights for researchers who build the smart exhibition environment and can gain promotion strategies fitting each cluster. First, visitors of ANT type show high response rate for promotion messages except experience promotion. So they are fascinated by actual profits in exhibition area, and dislike promotions requiring a long time. Contrastively, visitors of GRASSHOPPER type show high response rate only for experience promotion. Second, visitors of FISH type appear favors to coupon and contents promotions. That is, although they don't look in detail, they prefer to obtain further information such as brochure. Especially, exhibitors that want to give much information for limited time should give attention to visitors of this type. Consequently, these promotion strategies are expected to give exhibitors some insights when they plan and organize their activities, and grow the performance of them.
