본 논문에서는 노후화된 목조·석조 건축물의 균열을 탐지하는 기법을 소개한다. 본 기법의 목적은 석조·목조 문화재의 시간의 흐름에 따른 관리 소홀, 균열(벌레, 날씨, 기온 등), 배부름 현상에 의한 문화재의 손상을 사전에 방지하기 위함이다. 기존에 존재하는 목조·석조 건축물의 균열, 노후, 배부름 등 다양한 결함과 변형의 탐지 방법은 접촉식 센서를 이용하여 탐지를 해왔지만, 문화재 자체의 미관을 해칠 뿐 아니라 문화재를 추가로 훼손할 가능성이 있다는 문제점이 제시되었다. 이 문제를 해결하기 위해 문화재 비 접촉형 탐지 기법을 사용한다. CCTV 및 DSLR과 같은 관측장비로 촬영한 영상정보를 기반으로 문화재의 결함과 변형을 AI 영상분석 기반 방법으로 판단하는 문제를 제안한다.

In order to examine the safety of stone-built historic properties, it is necessary to apply different methods to the properties according to their categories, respectively. However, there is no consensus for the criteria on which item should be examined. To make systematic preservation plans for the historic stone buildings, it must be requested to consider various factors such as weights, structural imperfections, and natural disasters and so on. In this paper, the Jinjeonsaji three-storied stone pagoda were numerically analyzed through the finite element method to measure its weight and slope. In addition, it was studied how slope variations of the stone pagoda affect to the deflections and stresses caused by its weight. Finally, criterions were proposed to examine the safety of the stone pagoda.

Three-story Stone pagodas in Gameunsa Temple site, one of the early staged stone pagodas, has been known as a standard of Silla stone pagodas. A stone pagoda is not only a stone art work and but also a stone architecture. In understanding the stone pagoda it is very important to be approached with technological side in which we can investigate the stone pagoda deeply and as well as to have been approached with art historical view. Also it needs that we should see the stone pagoda in view of structural safety. We can get many high technique from our ancestors who made Gameunsajiseoktap. 1. To reduce any deformation such as relaxation and sinking of members which is caused by a heavy load the members such as the lower tier of the base is made up of the foundation stone and side stone in each, comprising one stone. 2. A special construction method for connection between wall stone and column stone in stereobates was invented. It is to make column stone projected partially and wall stone be caved in that two members should be jointed well. This unique method is not used any longer after the three-story Stone pagodas in Gameunsa Temple Site. 3. In each side upper and lower member are not engaged as the size of roof stones and support stones of roof stones are different. It can be done for a distribution of perpendicular load and a prevention for relaxation of members. 4. It makes sure that to make upper ends of support stones 10mm lower was to be avoid upper loads to it judging from survey in disassemblying east pagoda. It proves that ancestors who made this stone pagoda had a technique to understand the structural matters to make small members as big as possible, not to engage in joint, to avoid in ends of members from upper load.

The Myeongdongseongdang Cathedral, which was designated as Historic Site No. 258 in Korea, is a representative cathedral of Korean Catholic church designed by a French priest Eugene-Jean Georges Coste and completed in 1898. It is a Gothic-styled architecture constructed with bricks and stones. Lithological and mineralogical analyses determined that holy stone relics were made of marble and granite, and foundation stones are of pink feldspar granite. Deterioration mapping and ultrasonic measurement revealed main weathering and damage were exfoliation (40%) and black discoloration (37%) in the holy water basin, and exfoliation (6%) and discoloration (46%) in the exterior foundation stones. Ultrasonic velocity of the stones were calculated as 3,525m/s in the holy water basin and 2,795m/s in the exterior stones that indicated these stones were sorted into moderately to highly weathered rock. This was resulted from moisture and atmospheric pollutants around the cathedral.

Some reverse fault lines are passing through the alluvial fans and west hill slope of Bulguksa mountains including Mt. Toham in the directions of N-S and NW-SE. The study area is known as relatively unstable, because of active faults. Assuming on the record of Samguksagi about earthquakes, the architects in the construction of the Bulguksa Temple should have recognized the possibility of breakdown from the earthquakes and the need for an unique structure against at that time. Against earthquakes, Grengee technique, a stonework construction technique following wooden one and use of Chuduseok(Dongtleseok or Chumchaseok) were applied for the construction of the Bulguksa Temple. By designing the foundation stone with hole, a structure is prevented from modification that pillars secede from a foundation stone in spite of horizontal load of earthquake while wood construction is strong frame at earthquake. The Bulguksa Temple is usually evaluated to be a beautiful architecture from the appearances like the weight balanced structure with unique decoration. Impressive architectures are beautiful in balance and harmony coming from the important and specific rolls in its own way by each part of whole structure. This beauty comes from the science.

It is crucial to measure meteorological elements in relation to the biodeterioration of building cultural heritages. The Beopjusa and Seonamsa temples located respectively in Chungbuk and Jeonnam provinces, Korea, exhibit biological damage to the building cultural heritages and cause noticeable climatic differences. To compare biodeterioration environments of the abovementioned temples, 10 meteorological elements were observed, and particulate matter (TSP) was collected at each location. Furthermore, a correlation analysis was conducted between meteorological elements, and between meteorological elements and TSP. The local meteorology at Beopjusa temple characteristically showcased high total horizontal radiation, UV radiation, evaporation, wind speed, and TSP concentration, whereas, that at Seonamsa temple showcased high temperature, humidity, dew point temperature, air pressure, precipitation and number of days with precipitation. An elemental analysis of TSP revealed the presence of sae-salts at Seonamsa temple, and compared to that of Beopjusa temple, the monthly frequencies of biogenic aerosol and Fe-containing particles were higher. The correlation analysis showed that wind speed and humidity were major meteorological factors at Beopjusa and Seonamsa temples, respectively. Subsequently, the characteristics of the local meteorology at Seonamsa temple are expected to affect the biological damage of the building cultural heritages, which is favorable for the growth of various organisms.

As a monumental building in the form of an arch, an archway has the characteristics of praise and honor. More and more historic, cultural and social connotations are given during the development of history. Four archways that are located on the middle route of the Red Gate Palace in the Mount Tai Scenic Area were chosen for research. Based on a literature review and field investigation with a visual analysis method, the physical attributes, spatial scale, perceptions and functions of the archways were discussed. The results were as follows: The archways in the research area are all made of stone. According to building location, they are classified into two types: Cultural archway and temple archway. Regarding functions, they are divided into symbolic archway, memorial archway and portal archway. From the point of view of form and scale, the Confucius Boarding Archway enjoys a higher standard than the other three. This reflects the importance of Confucian culture on Mount Tai. Regarding spatial scale, the archway becomes the focus in a restrictive linear space by an object-to-object and person-to-object comparison. Visitor experience of crossing the archways is strongly enhanced as it acts as entrance and exit, and it has the function of guiding sight since the arrangement of the archways further extend the line of sight. Couplets and inscriptions on the archways increase a sense of expectation for visitors on their way to the top of Mount Tai.

The Three storied Stone pagoda in Gameunsa Temple site, one of the early staged stone pagodas, has been known as a standard for Silla stone pagodas. A stone pagoda is not only a stone art work and but also a stone structure. Most studies and investigation of the stone pagoda has done mainly based on style and chronological research according to an art historical view. However, there is not an attempt to research the stone pagoda as a stone architecture. Most Korean experts at the stone pagoda has art history in their background. Engineers who can understand the structure of the stone pagoda are very limited. More architectural and engineering approach is need to research not only art historial understanding but also safety as a structure. We can find many technical know-how from our ancestors who made stone pagodas. 1. To reduce any deformation such as relaxation and sinking of BuJae which is caused by a heavy load, the BuJae (consist of a foundation stone and lower stereobates) should be enlarged. 2. A special construction method for connection between Myonsuk and Tangjoo was invented. This unique method is not used any longer after the Three storied Stone pagoda in Gameunsa Temple site. 3. The upper BuJae and the lower BuJae are missed each other by making a difference of Okgaesuk and Okgaebatchim in size. It is done for a distribution of perpendicular load and a prevention for relaxation of BuJae. 4. The center of gravity in the BuJae is located to the center of the stone pagoda by trimming the upper surface of the Okgaebatchim into a convex shape. The man who made stone pagodas had excellent knowledge on the engineering and techniques to understand the structure of the stone pagodas. We can confirm it as follows: the enlarged BuJae, dislocated connection between upper Bujae and lower BuJae, and moving the center of gravity close to the center of the stone pagoda.

This study concerns the Baekje Traditional Garden, one of the open spaces in the Lotte Resort in the Baekje Historical Reappearance Complex, which is part of the comprehensive plan for specific areas in the Baekje cultural area. The Baekje Traditional Garden has historic value, and its excellent garden style influenced the ancient Japanese gardens. This study dealt with three issues: (1) The context in which Lotte Buyeo Resort accepted the Baekje Traditional Garden, particularly the background and process of such; (2) The original form of the Baekje Traditional Garden; and (3) How the Baekje Traditional Garden should be represented in the open space of the resort. Representation is accomplished in two ways: using the structure of the original garden and in the borrowing of elements. For representation using the structure of the original garden, Imrugak was used as the main entrance space, and Wolsunjung was represented from the Ganbuklee remains. In the rear garden are wave watercourses and other garden facilities of the Wanggungri site in Iksan. Borrowing of elements, on the other hand, was accomplished in the plant plan and detailed development. In addition, mountaintops (three mountains and five mountain summits), a clean stream between mountains, and a pine forest are visualized in the garden. This is the representative landscape of the Taoist hermit world that appeared in the Baekje Gilt Bronze Incense Burner and Landscape pattern. The significance of this study is twofold. First, the Baekje Traditional Garden is a fresh trail because there has been no previous research concerning it. Second, while past research concerning traditional spaces focused on the results of representation, this study focused on the process of representation. This means that this research work tried to extend the study concerning the representation of traditional spaces from the conceptual to the practical approach. This study, however, also has its limitations. The authenticity of the representation suggested in this study may be questioned later because efforts have been made to preserve the original Baekje Traditional Garden. In addition, this study should seek a balance between authenticity on one hand and amusement and diversity of experience on the other, because the site is a resort.

Buddhist stupas, which are a symbolic architecture of Buddhism and enshrine the Jinsinsari of Buddha, were reinvented as stone stupas appropriate for the natural soil of Korea from existing wooden stupas around the 7th century after the introduction of Buddhism. Later, the construction of a stone stupa was expanded to local areas from the central area around the 9th century; thus, stone stupas of more diverse local colors were built in a nationwide scale, and today it is called a "country of stone stupas". While focusing on the stylistic interchanges between stone stupas, which were established in each region in accordance with the localization of the establishment of stone stupas that was begun actively from the 9th century, this paper selected several cases of stone stupas among about 50 stone stupas in the Gangwondo-region. First, the study compared the stone stupas and Buddhist priest tower of Seollimwonji, Jinjeonsaji, and Geodonsaji, which are located at the same temple site as the current Buddhist priest tower, from among typical Silla style stupas that match the 9 stone stupas in the Gangwon-do region. This is because stylistic interchanges were possible while there were mutually organic relationships between Buddhist statues such as stone stupas, Buddhist priest towers, stone lanterns, and Buddhist pedestals, which used the same stone material along with the expansion of Buddhism to local areas in accordance with the spread of Zen Buddhism in the 9th century. Second, a comparison was made of the stylistic similarities between the Woljeongsa Palgakgucheong (eight sides nine-storied) stone stupa and the Sinboksaji Samcheung (three-storied) stone stupa, which are totally different in regard to the number of stories and the flat form. These two stone stupas are representative Goryeo stone stupas. The Woljeongsa stone stupa is a Goguryeo-oriented stone stupa with many sided multiple stories whereas the Sinboksaji stone stupa has been known as an early case of the insertion of the support of Tapsin in each story. Although the two stone stupas may look very different, but through close investigation it was confirmed that there were many stylistic interchanges between them and not only the seated stone Buddha statue in the cylinder jewel case in front of the stupa but also the stone stupa established by the same master. Consequently, this paper aimed not merely to mention the simple patterns of stone stupas, but, further, to trace the interchange in patterns in accordance with the construction period based on those patterns.
