Artificial intelligence technology in the medical field initially focused on analysis and algorithm development, but it is gradually changing to web application development for service as a product. This paper describes a Urinary Stone segmentation model in abdominal CT images and an artificial intelligence web application based on it. To implement this, a model was developed using U-Net, a fully-convolutional network-based model of the end-to-end method proposed for the purpose of image segmentation in the medical imaging field. And for web service development, it was developed based on AWS cloud using a Python-based micro web framework called Flask. Finally, the result predicted by the urolithiasis segmentation model by model serving is shown as the result of performing the AI web application service. We expect that our proposed AI web application service will be utilized for screening test.

The stone Buddha statue of Sangunsa Temple at Bukhansan in Goyang, Gyeonggi Province, is an excellent example of stone Buddha statues created in the late 15th century. On the base of the figure, there is an inscription, which informs that it was produced in 1497. In recognition of this significance, it was recently designated as a tangible cultural asset in Gyeonggi-do. Thus, this paper tried to evaluate the value of the statue by analyzing iconography and style. The characteristics of a typical 15th-century style that the Buddha statue of Sangunsa Temple shows are the form of ushnisha, the way clothes are worn, the form of a w-shaped chest muscle, and the simple lotus pedestal. On the other hand, the elongation of the waist and the disappearance of the waistband on undergarments are new forms of Buddha statues in the 16th century. Besides, parting the hair in the middle of the head and leaf-shaped short ribbon draped on undergarments are unique features that only appear on the statue of Sangunsa Temple. Sangunsa has been known to be built in the early 18th century based on Bukanji compiled by Seongneung in 1745, and Bongeunbonmalsaji composed in 1943. However, the statue was created in the late 15th century, before the establishment of the temple in the early 18th century. Therefore, this paper briefly reviewed the history of Sangunsa Temple, focusing on the initial period, referring to the historical sites and the relics that were passed on to the temple, as well as the literature records. The data newly referred to in the study are as follows: Sangunsa Stone Pagoda, presumed to be from the Goryeo Dynasty; the Stone Buddha Statue of Sangunsa; Wooden Amita Triad Buddha Statue of Sangunsa. According to the data and contrary to previously-held beliefs, Sangunsa Temple is believed to have been operating since the Goryeo Dynasty. It can be inferred through analysis of the stone Buddha statue of Sangunsa Temple that the size of the Temple before the 18th century was not very large.

Inner walls of the stone chamber of West Ancient Tomb No. 1 and 2 in Neungsan-ri, Buyeo-gun have been inspected for possible trace of murals. Tomb No.1 has a rough surface finish of the stone wall and no traces of murals was observed in any part of the stone walls except the ceiling part of the main chamber. On the ceiling surface, there is black colored area, which showed same visual characteristics for both the surface and interior upon slight scratch of the surface, suggesting that it may not be a painted layer. In addition, this black material is not artificial stuff like black ink but is confirmed as biotite from X-ray diffraction analysis that is one of the constituents of the stone wall. In case of tomb No. 2, white material, that is confirmed as lime(calcite, CaCO3) by X-ray diffraction analysis, was observed on the wall surface of the east, west and north, suggesting possible existence of murals. The lime layers, however, are located mostly on the entrance of east wall of main chamber and the place of passage whereas they are observed only in lower parts on the other walls. It may have been formed by the inflow of soil and lime from the outside as the form of the lime layer in the east wall corresponds to the traces of soil and lime deposited from the thief pit. Furthermore, the filling material found in the gap between the stone slabs of the four directions and the ceiling was confirmed as clay soil, which is different material from the lime present on the stone wall surface. If the lime layer had been artificially constructed for the purpose of creating murals, it would have been more reasonable to use lime as well in the gap between the stone slabs of the four directions and ceiling. In this regard, we conclude that there are no murals in the Tomb No. 2 in the Neungsan-ri.

This paper deals with the stone standing Avalokitesvara statue in Jeonghyesa Temple that was created by Mangong in 1924. The stone standing Avalokitesvara statue of Jeonghyesa Temple is the earliest extant Buddha statue produced by Mangong, and symbolism was given to Jeonghyesa in the process of its reconstruction. So far, there has been no study that has approached ideas and beliefs through Buddhist studies led by Mangong and specific relics. In order to proceed with this study, Mangong's legal words and anecdotes and newspaper articles during the Japanese colonial era were used to trace the dynamics of Jeonghyesa and Sudeoksa during Mangong's reign, and to investigate the effects obtained from the creation of the large Bodhisattva statue and the meaning of its location. In addition, an interview was attempted with the descendants of master, who were in charge of the sculpture at the time, to confirm the exact construction period and the list of craftsmen. It is judged that the stone standing Bodhisattva statue of Gwanchoksa Temple has been influenced by the double covering and square crown seen in the standing stone statue of Avalokitesvara Bodhisattva of Jeonghyesa Temple, the large hands compared to the body, the proportion between the head and the body, and the sense of enormity felt in the body like a stone pillar. Therefore, we looked at how the standing stone Bodhisattva statue of Gwanchoksa Temple, which was produced in the early Goryeo Dynasty, could have influenced the creation of the Bodhisattva statue in the modern period. A multilateral analysis was attempted on how the image of the Gwanchoksa Bodhisattva statue, which was used as a symbol representing Chungcheongnam-do in the Chosun Exposition held in 1929 and the visit to Gwanchoksa Temple, which began with the laying of the railroad during the Japanese colonial period, was used from the viewpoint of the succession and transformation of the style. With this study as an opportunity, it is hoped that the understanding of the prehistoric Mangong representing the modern period and the horizon of Korean Buddhist sculpture research in the modern period will be broadened.

The main structural elements of historical masonry arch bridges are arches, spandrel walls, piers and foundations. The most vulnerable structural elements of masonry arch bridges under transverse seismic loads, particularly in the case of out-of-plane actions, are spandrel wall. The vulnerability of spandrel walls under transverse loads increases with the increasing of their length and height. This paper computationally investigates the out-of-plane nonlinear seismic response of spandrel walls of long-span and high masonry stone arch bridges. The Malabadi Bridge with a main arch span of 40.86m and rise of 23.45m built in 1147 in Diyarbakır, Turkey, is selected as an example. The Concrete Damage Plasticity (CDP) material model adjusted to masonry structures, and cohesive interface interaction between the infill and the spandrel walls and the arch are considered in the 3D finite element model of the selected bridge. Firstly, mode shapes with and without cohesive interfaces are evaluated, and then out-of-plane seismic failure responses of the spandrel walls with and without the cohesive interfaces are determined and compared with respect to the displacements, strains and stresses.

A museum's collections is fundamental factors to construct important activity of museum performing a role as cultural facility for learning, education and research. Therefore, conservation of collections through appropriate environments is previously established in step of planing a museum. Hereby, the purpose of this study is to set up the classification of collections and suggest a useful guidance of the storage division in a domestic museum. The results of this study are as follows. First, the main factors of deterioration are temperature and relative humidity in a museum storage, so classification of collections should be set up according to the objective standards of these factors. Second, the classification of collections can be performed as follow: the group for nonorganic materials subdivide metal, chinaware, earthenware, and jade stone, the group for organic materials subdivide leather hair paper fabric, bone horn shell mound and wood herbage and the group for composed materials. Third, for storage division of a domestic museum, basically has to consider that it is reasonable to plan $4{\sim}5$ storages in metal, jade stone, chinaware earthenware, and organic materials of $1{\sim}2$ units in case of a serial of history like archaeological, antique museum. And in case of folk relics of modern and contemporary arts are collected, it is reasonable to plan over 5 storages add composed materials to foregoing classification.

This paper is to clarify on the characteristics of the Haeeumwonji and the Main Palace of the Goryo Dynasty. The architectural techniques and construction methods such as embankment, stylobate, stairway, foundation stone, and pave are similar to those of the Haeeumwonji and the Main Palace of the Goryo Dynasty. In order to express the hierarchy of the area and building, the materials, techniques, and forms of the embankment, stylobate, stairway, foundation stone and pave were used differently. The paving of the floor of the main building and area is also an active expression of the hierarchy and status of the building area and the building through the use of building materials, techniques and forms. This result confirms the support of Goryeo royal family and the upper class for the construction of Haeeumwonji, which is recorded in the historical documents. And it also shows that the architectural techniques and processing method of the same period were shared in the capital and provinces, which is an important clue that proves that the capital-centered architectural technology has spread to the provinces. It is expected that additional research will be needed on the characteristics of the period of 12th century architecture technique in which Haeeumwonji was built.
