Most of Korea's Kyungmaedorock(auction book: 競賣圖錄) and pictorial record of exhibitions in the modern times were usually published in the 1930s. Although 1930s were periods of the Great Depression when economic slump continued because of the aftereffect of the slump in the stocks issued by the US in 1929, during this period, Japan began regular continental invasion starting from invasion of the northeastern area of China. To curio dealers, the 1930s were 'boom period of curio transaction' and in urban cultural aspects, the period is evaluated as the one when the first step of modernism was formed. Collection, photo-printing and arrangement of the data related to modern exhibitions including the Auction Book being published at that time are very important because they enable us to know characteristics of fine arts in the transition period from paintings & writings to fine arts in addition to enabling us to revert the circulation history of our paintings & writings and curios. Furthermore, these data will become important data for reconstitution of the circulation history of the Eastern Asia's modern art works. Although the pictorial record of Joseon's Exhibitions of Chinaware and Wooden Works(朝鮮陶磁木工展) is a small and thin one, it records our country's high level chinaware and wooden works. Although we can't know the exact time for 'Joseon's exhibitions of chinaware and wooden works', they are assumed to have been held in Tokyo, Japan in the 1930s and there seems to have been sale of works, too. As such, studies of the books such as the auction book and exhibitions under Japanese imperialism have the first importance in the fact that through which we can examine the course of outflow of our art works to Japan. Furthermore, they can be studies of art-sociology that examine flow and phase of recognition and taste of art works of those days. And from now on, comparative studies of auctions and exhibitions being held in Japan such as Tokyo, Osaka and etc. as well as art markets in Seoul during modern times would also be necessary.

The purpose of this study is to provide useful information for establishing efficient marketing direction by investigating the performance(satisfaction) and importance of the display of dining space for hotel banquets. The importance and satisfaction scores of the display of dining space were measured on the five-point Likert scale. The results were summarized as follows. 'Taste of food(4.53 point)', 'freshness of food materials(4.50 point)', and 'indoor cleanliness(4.38 point)' were considered highly important while 'carpet shape of the floor(3.68 point)' and 'art objects(3.69 point)' were scored low. As for the factors of satisfaction, 'freshness of food materials(3.86 point)', 'taste of food(3.85 point)', 'indoor cleanliness(3.74 point)', and 'overall cleanliness of tables(3.73 point)' were considered highly satisfactory while 'art objects(3.42 point)', 'item decoration(3.44 point)', 'furniture and accessory decoration(3.45 point)' were scored low. As a result of analyzing difference between importance and performance of the display of dining space, importance(4.02 point) was much higher than performance(3.60 point). For the IPA result, customers made much account of 'taste of food', 'freshness of food materials', 'indoor cleanliness', 'overall cleanliness of tables', 'cleanliness state of a banquet hall' and so on, so they were regarded as the items to be continuously cared for. Also, intensive care was needed in such factors as 'indoor temperature', 'food vessels', 'soundproofing' and 'colors of a banquet hall' due to low customer satisfaction.

The Korean art history academia has lately been carrying out active research on the Korean art market and art collectors. This area of research is significant in that it attempts to overcome the limitations of previous research trends focused on tracing back and analyzing preeminent masters, their schools and their influence, and approach new subject matters such as art and society, circulation and consumption of art works, which were unapproachable with previous research methods. This paper examines the life, artwork and art collection activities of Songeun(松隱) Yi Byeong-jik(李秉直: 1896-1973), an outstanding painter, calligrapher and art collector during the Japanese colonial period. The primary purpose of this paper is to advance the research project the author has recently initiated on modern Korean art collectors by reconstructing parts of this major art collector's individual lifestyle and to generally identify the art collection activities and the art works that he kept. Yi Byeong-jik, one of the preeminent art collectors during the colonial period, disposed his voluminous collection through two auctions in 1937 and 1941, and then held another auction two weeks before the onset of the Korean War on June 25, 1950 to sell off the remaining works. It seems that the reason why Yi had auctioned off his collections was for the purpose of investing in education. The tale that Yi safely kept 'Sam-guk-yu-sa(三國遺事),' which is considered a national treasure, even through the time of turbulence is evidence of his exemplary behavior as a model art collector. He may be one of the best examples of what an art collector should be in terms of giving back to the society and preserving things of beauty and value. However, one factor that limited and defined Yi's life was that he was a eunuch. This aspect of his life could be pointed out as the biggest factor that stopped him from becoming a mainstream participant in the art world despite his influence as a great painter, calligrapher, significant art collector, and discerning connoisseur.

${\ll}$Three Purities Album${\gg}$ in the Kansong Art Museum is an album of poems and pictures of apricot tree, orchids and bamboos drawn by Lee Jeong. Given that the poems and pictures in the album were drawn by Lee Jeong who has been recognized as a person who established the standards of ink bamboo drawings in the Joseon Dynasty, the album is highly valuable. Nevertheless, there are more values and meanings that Three Purities Album has. The production circumstances and transmission processes of Three Purities Album include the historical characteristics and meanings of the time so that it is also worthwhile as a historical material. During the Japanese Invasion of Korea in 1592, Lee Jeong was stabbed with a sword by Japanese invaders and got injured. After he suffered, he tried to make his masterpiece in his lifework and finally created Three Purities Album. For the work, Lee Jeong received memorial writings from Choi Rip, Cha Cheon-ro and Han Ho, and asked them writings. They were the best literary men in the poem and calligraphy fields at that time. Yu Geun, Lee An-nul, and Yu Mong-in made writings and poems to praise his work. Likewise, ${\ll}$Three Purities Album${\gg}$ is the 'treasure of the time' created through the participation of the best literary men at that time. Given the aspects, it is fair to say that ${\ll}$Three Purities Album${\gg}$ is not simply a personal artwork of Lee Jeong, but is a comprehensive artwork and also a cultural monument created through the skills and capabilities of the literary artists in the middle of the Joseon Dynasty. After the death of Lee Jeong, Three Purities Album was handed over to Hong Ju-won. But, during the second Manchu Invasion into Korea in 1636, the album was in danger of disappearance by fire. As of now, there are still signs of fire in it, which vividly shows the urgent situation at that time. After the second Manchu Invasion into Korea in 1636, Hong Ju-won recovered some damaged writings with the help of Yoon Shin-ji. Since then, the album had been handed down as a family treasure over the next 7 generations. It can be found in the writings by Song Si-yeol and Uh Yu-bong. Unlike the literary men who praised Three Purities Album in terms of its work when Lee Joeng was alive, they focused on the transmission courses of the album and involved persons. That seems to be because the stories and characters appearing in Three Purities Album impressed the later literary men and were meaningful to them rather than the album itself. It strongly reflected the positions of Hong Jung-gi and Hung Sang-han who asked for writings as the descendants of Hong Ju-won. That is because the traces of the persons involved in Three Purities Album are the causes for admiring their ancestors and enhancing their political legitimacy and family dignity. Therefore, in this aspect, it is possible to witness the fundamental causes of the unique artistic awareness by East Asian people who consider their historical meanings as well as the aesthetic value of artworks significant. Unfortunately, during the Japanese invasion at the end of the Joseon Dynasty, Three Purities Album was handed over to Japanese Tzuboikouso. But, fortunately, Jeon Hyeong-pil who made an effort to regain our cultural assets by investing his entire property during the Japanese Imperialism regained the album, which is now preserved in the Kansong Art Museum. ${\ll}$Three Purities Album${\gg}$ truly includes the whole processes to overcome national crises that Korean people experienced during the Japanese Invasion in 1592, the second Manchu Invasion of Korea in 1636, and the Japanese Imperialism, and it shows the sufferings of our cultural assets and the history of preservation. Also, the album shows that one artwork is able to accumulate its historical meanings in the process of transmission and thus enhances its meanings and values. ${\ll}$Three Purities Album${\gg}$ features accumulative and constant historical meanings and it is a typical case showing that an artwork is plenty of aesthetic and historical values. It is expected that this work will contribute to promoting more studies on finding historical meanings and hysteresis of artworks.

The influence of acid rain on the marble cultural properties investigated in two ways : 1) marble samples similar to that of Wongak-sa 10-story pagoda were directly exposed to rain in air at Chongro and Kwanghwamun sites; 2) marble samples under a protective facility were indirectly exposed to rain. The quantity of corrosion products and variations of calcium ion to rain were analyzed. The result shows that the corrosion qantity of the marble samples exposed directly under 1~8 mm rainfall in the Chongno and Kwanghwamun sites were similar, but those were 7.7 times higher than those indoor. Concentration of anions were higher than that of cations among the ion concentration over 40% in the early 1 mm rainfall. Calcium ion was produced over 30%. Because the monuments of marble, limestone and sandstone were affected by acid rain, it may be necessary to establish policies for the conservation on the National Treasures made of these materials.

The missing child problem is no more a personal problem. It became a social problem that all parents must consider. To this, this study applies USN/RFID technology integrated with GIS for the prevention of missing child. Although RFID is not designed for location sensing, but now it is regarded as a device to facilitate real time location awareness. Such advantages of RFID can be integrated with 4S(GIS/GPS/LBS/GNSS) achieving much synergy effects. In order to prevent kidnapping and missing child, it is necessary to provide a missing child preventing system using a ubiquitous computing system. Therefore, the missing child preventing system has been developed using high-tech such as RFID, GPS network, CCTV, and mobile communication. The effectiveness of the missing child prevention system can be improved through an accurate location tracking technology. This study propose and test a location sensing system using the active RFID tags. This study verifies technical applied service, and presents a system configuration model. Finally, this paper confirms missing child prevention system utilization possibility.

A study on conservation of outdoor painted sculptures has begun to receive attention as increasing numbers of the sculptures, but it is still in an early stage in South Korea. In the case of a painted outdoor object which has been exhibited in National Museum of Modern and Contemporary Art (MMCA), 'Black nana' produced by Niki de Saint Phalle in 1964, deterioration was observed, such as flaking and discolouration of paint layers due to ultraviolet light and a sudden temperature change during an outdoor exhibition. For this reason, prior to treatment of the sculpture, to find out the painting techniques and materials applied, cross section, FT-IR, Raman and Py-GC/Mass were conducted. As a result, the type and colour of the paint agree with results of the other studies as well as deterioration pattern. It is expected that the results of this study will be utilized for treatment proposal and conservation material selection of 'Black nana'. In addition, to determine the artist's intention of the artist, cooperation with the foundation of Niki de Saint Phalle and artist's assistants will be carried out.

Plastic has been widely used in modern artworks' materials due to its merits of process ability and mass production. In the country, value of plastic artifact is increasing but the field of plastic study is limited to industrial purpose. In this study, Identification methods of plastic were performed by SPME-GC/MS and pyrolysis-GC/MS using trace of samples. As a result of identification using SPME-GC/MS, aromatic compounds were identified from polyvinyl chloride. And alkane compounds were identified from polyethylene, and polypropylene. Aromatic compounds were identified from polystyrene, and diethylene glycol appeared in polyurethane based on polyester was identified from polyurethane. As a result of identification using pyrolysis- GC/MS, aliphatic alkenes compounds and phthalate(DEHP) were identified from polyvinyl chloride. Aliphatic alkenes compounds and phthalate(DIBP) were detected from polyethylene. 1-hexene, etc., were detected from polypropylene, aromatic compounds were identified from polystyrene, and methylene diphenyl diisocyanate which is polyurethane basic material was confirmed from polyurethane. This study suggested that non-destructive SPME and pyrolysis-GC/MS are useful to identify compounds particularly polystyrene and polyurethane. These two analytical methods were expected to be applied for identification of unidentified plastic artworks before conservation treatment.
