Sudden increase exceeding 30million in the number of smart phone users, and rising interest in the technology of augmented reality, is now trying to combine it with AR technology in other areas very much. The field of cultural heritage, which has been constructed by the Internet and 3D technology, is not unusual and this field is now rapidly changing thanks to the AR technology which can make users experience cultural heritage with high reality. The Palaces in Seoul, however, use fragmentary tools of information - lack of heritage commentators, leaflet, etc, even though the number of visitors is gradually increasing. Therefore, three-dimensional and comprehensive cultural heritage information service is needed with the guidance in the mobile era. This study utilizes the AR technology for building the Deoksugung Tourist Information Service Application(App.) applying the markerless-based recognition technology which is a more advanced tool than the location-based AR technology. This new AR technology can switch perceived real images such as the tablet of the King in the Palace of in the real world, patterns and pedestals into virtual world, which can reproduce the damaged cultural assets as 3D. This also composes photos of the past with the current buildings, which can increase people's interest and absorption of the contents, and helps them understand and be aware of Korean traditional culture and cultural heritage effectively. In addition, convergence between IT new technology, Augmented Reality(AR) and humanities through storytelling based implementation of cultural heritage in smart phone is attempted to demonstrate that there is strength in which augmented reality technique exerts infinite creativity based on actual reality world.

Cheongpyeongsa Temple was originally built in the early years of Goryeo Dynasty, but its current structural framework was made by the Lord Jinrakgong Lee Ja Hyeon(1061-1125) of the middle Goryeo period based on the Zen thought after he began living in the Cheongpyeong mountain around the temple in 1089. The purpose of this study is to conceptualize, based on old documents, historical changes of the appearance and survival of man-made structures with in the Zen garden formed and developed after Lee Ja Hyeon laid the foundation for Munsuwon Zen garden. Among the eight, outside-the-temple hermitages built at the time of Lee Ja Hyeon's Munsuwon Zen garden, only three hermitages, which are Sik-am, Gyeonseong-am, Yangshin-am had been remaining thanks to restoration and repair until late Joseon Dynasty and preserved as symbolic hermitages. Also, the Yeongji Pond built at the time of Lee Ja Hyeon still remains as precious landscape relics which is meaningful as a genuine Goryeo-period pond. The nine pine trees said to be planted by Lee Ja Hyeon remained until middle 1800s through their descendant trees. When the Buddhist monk Bowoo Daesa(1509-1565)changed the name to Cheongpyeongsa Temple in middle Joseon based on the Munsuwon Zen garden built by Lee Ja Hyeon and greatly expanded it, he newly built and expanded all buildings inside the temple except for Neunginjeon(main temple building), resulting in the present temple structure. In addition, by greatly enhancing the level of scenery by reconstructing Yeongji Pond outside the temple area and transplanting garden plants from the royal court, he made Cheongpyeongsa Temple the most prosperous Zen garden in its history. But after the mid-1800s, which is late Joseon period, Cheongpyeongsa Temple failed to thrive further and began to decline, and so currently most buildings of the Zen garden have disappeared except for some parts of the temple and other facilities are neglected.

This research aimed to develop the district unit plan simulation using procedural modeling based on shape grammar. For this, Esri's CityEngine 2020.0 was selected as a main development tool, and Inside Commercial Area in Bangi-dong, Songpa-gu, Seoul as the research site where about 25% of the total area was developed over the past five years. Specifically, the research developed the simulation through the following three phases of Data-Information-Knowledge after selecting necessary parameters. In the Data phase, 2 and 3 dimensional data were obtained by utilizing data sharing platforms. In the next Information phase, the acquired data were generated into various procedural models according to the shape grammar, and the 2D and 3D layers were then integrated using relevant applications. In the final Knowledge phase, three-dimensional spatial analysis and storytelling contents were produced based on the integrated layer. As a result, the research suggests the following three implications for the simulation development. First, data accuracy and improvement of sharing platforms are needed in order to effectively carry out the simulation development. Second, the guidelines for district unit plans could be utilized and developed into shape grammar for procedural modeling. Third, procedural modeling is expected to be used as an alternative tool for communication and information delivery.

Particulate matter(PM) is one of the leading causes of lung cancer. Recognizing its considerable risk to human health, people change their behaviors when a concentration level of PM is high. The impact of particulate matter on urban activities may vary depending on the lasting days of PM and PM matter alerts. In addition, the level of averting behavior may vary depending on the types and physical characteristics of urban activities and the degree of vulnerability to PM among people. Although the way people respond to PM may vary depending on these various factors, previous research evidence on this is very insufficient. Therefore, this study multilaterally analyzed the impact of PM on the urban activities in Jongno-gu, one of the CBD areas of Seoul. For this, we linked SKT's mobile phone signal data to land use data to extract the daily number of active people by urban activity types and ages. According to multiple regression analysis, the averting behavior varies depending on the type of urban activity, the physical characteristics of the place of activity(inside and outdoor), the lasting days of PM, PM alerts and the age of people. The results of this study can be used as basic data to policy makers who establish policies for adapting to air pollution policies by providing various effects of PM on the urban activities.

This study attempts to identify the ways of reducing the floor impact sound, by applying six different types of the reinforced bar girders and stirrup arrangements to the Structure: (1) the longer-direction girder arrangements (2) the shorter-direction girder arrangements (3) the diagonal-direction arrangements (4) the longer-direction girder arrangements with stirrups (5) the shorter-direction girder arrangements with stirrups (6) the diagonal-direction arrangements with stirrups. In order to identify the most effective structural changes, each slab was tested with bang machines, measuring the level of the sound impact. The results showed that the longer-direction girder arrangements with stirrups were the most effective one. In addition, the effectiveness of slab was found to be remarkable, showing the level of minimum 1dB to maximum 5dB, where the slab was compared with the control models without girders and stirrups. In conclusion, it is suggested that the longer-direction girder arrangements with stirrups could possibly be applied to the Wall Structures to minimize the floor impact sound.

Lacquer, in addition to high-end crafts such as lacquerware inlaid with mother-of-pearl, was an important strategic material used in a wide range of fields such as industry, architecture, and munitions during the Japanese colonial era. In particular, as the demand for lacquer used in munitions soared in the 1940s when the war started, a ticket system was introduced to restrict its distribution. Meanwhile, Japan experienced a chronic shortage of lacquer as a result of the rapidly increasing demand for it, and thus went on to import Chinese lacquer after the late 19th century. After the 1910s, the market share of Chinese lacquer reached 90%, and the local situation in China began to affect the supply and demand for lacquer in Japan. To counteract the issue, the Japanese government increased the production of lacquer in Joseon. As for the project to increase lacquer production in Joseon, objective indicators were prepared through a number of tests in the 1910s and 20s, which paved the way for the project to begin in earnest in the 1930s. Lacquer trees were planted and training classes on how to collect lacquer were held throughout the country. The Japanese government promoted the lacquer production industry as a promising side job for Koreans. The project, implemented in various parts of the country, reaped fruitful results, and it provided the basis for lacquer production in Korea that has continued to this day. At that time, the major regions in the southern part of the country where the project was concentrated were Wonju, Okcheon, and Hamyang, regions that are still known today as major production sites. The improved method of collecting lacquer taught to Koreans by the Japanese has now become the main method of collecting lacquer in Korea. This study attempts to identify the current status of the project to increase lacquer production through various records from the Japanese colonial era with a view to contributing to the study of modern lacquer craft history.

In order to induce users to purchase excellent products in the water industry that satisfy the technical standards of excellent products, in this study, it is to present the advantages of the cost aspect of the pumps as the objective basis. It will be to promote technology development of domestic water companies and to create a virtuous cycle structure in the water industry. In order to present an objective basis for the merits in terms of cost, an economic evaluation was conducted through life cycle cost analysis. For the LCC analysis, initial cost (pump cost and installation cost), operation cost (energy cost and maintenance cost) and demolition cost (disposal cost and residual value) are searched and calculated. As the results of comparison on two capacity of pumps, the energy cost of the excellent pump is 212 million KRW lower than the that of general pump in the large pump. The cost of excellent pump was 17 million KRW lower than that of general pump in small capacity pump. As the results of sensibility test, if the product is developed in the direction of improving pump efficiency and increasing the replacement cycle of consumables, it is predicted that the effect on LCC will be large.

This study attempted to organize the transition process of Royal Library (Gyujanggak) in chronological order, analyze the flow and find diachronic meaning during Gojong period, the most confused time at home and abroad prior to modernization. For this, first, the total status quo of King Gojong's library and book storage which played role of Royal Library and a personal library in Gojong period was investigated. Second, based on the current status of the investigation, the transition process from the Royal library in the early days of King Gojong to the Imperial library during the Korean Empire and its meaning were considered with the Annals of the Joseon Dynasty, Seungjeongwon diary, various catalogs and historical records. Third, the changes of space-time and aspect of Royal library through the palace of Gyeongbokgung, Changdeokgung, and Gyeongungung were examined to draw a sociopolitical meaning by schematizing each palace. As a result, first, King Gojong conjugated Kyujanggak as a device to strengthen the royal authority and accommodate Western culture in the process of modernization. Second, the crucial spaces containing the political orientation of King Gojong, such as the present king's portrait storage place, library(book storage), and office, formed a separate hall across Gyeongbokgung, Changdeokgung, Gyeongungung, and gradually changed into a Western architectural style.
