The hydrogeochemical study on the 15 natural waters was carried out in the vicinity of tunnel excavation site of Donghae largely composed of granite and limestone. The water samples can be classified based on their chemical characteristics into two groups; waters draining in the granitic region(group 1) and the limestone region(group 2). This classification was also confirmed by statistical examination through cluster analysis, and the tunnel seepage waters collected at the same site appear to be included in group 1 and 2 by their sampling period, respectively. According to factor analysis, the waters of group 1 art mainly represented by the weathering of plagioclase to kaolinite and those of group 2 are characterized by the dissolution of calcite. Different properties of the tunnel seepage waters are thought to be resulted from the effective waterproofing processes conducted during the sampling interval to the surface and subsurface leakage zones at the granitic region, which contributed to the change of groundwater flow system. However both the tunnel seepage waters seem to have thermodynamically interacted with rock-forming minerals in their wallrocks. The mixing ratio of the waters from two groups and water-rock interactions are evaluated quantitatively for the tunnel seepage waters through the mass balance approach, and the results are identical with the previous conclusions in this study.

The WIPP (Waste Isolation Pilot Plant), located 42km east of Carlsbad, New Mexico (NM), in bedded salt 655m below the surface, is a mined repository constructed by the US DOE for the permanent disposal of transuranic (TRU) wastes generated by activities related to defence of the US since 1970. Its historical disposal operation began in March 1999 following receipt of a final permit from the State of NM after a positive certification decision for the WIPP was issued by the EPA in 1998, as the first licensed facility in the US for the deep geologic disposal of radioactive wastes. The CCA (Compliance Certification Application) for the WIPP that the DOE submitted to the EPA in 1966 was supported by an extensive performance assessment (PA) carried out by Sandia National Laboratories (SNL), with so-called 1996 PA. Even though such PA methodologies could be greatly different from the way we consider for HLW disposal in Korea largely due to quite different geologic formations in which repository are likely to be located, a review on lots of works done through the WIPP PA studies could be the most important lessons that we can learn from in view of current situation in Korea where an initial phase of conceptual studies on HLW disposal has been just started. The objective of this art report is an overview of the methodology used in the recent WIPP PA to support the US DOE WIPP CCA and some relevant results completed by SNL.

This paper aims to consider history and value of the Mingshansi Grottoes, a complex of Buddhist rock sculptures in Anyue County, Sichuan Province, China. Mingshansi Shiku, not that far from Baodingshan Grottoes at Dazu District, Chongqing City, is an important art work of Liu Benzun sect. Even though there are not many niches and sculptures in the Mingshansi Shiku, it was designated as a Major Historical and Cultural Site Protected at the National Level due to its large scale and highly valued art works in it. In the Mingshansi Grottoes there is not any information inscribed on the rockface about when the grottoes were established. Because a stone pagoda, which had information about when and by whom they were established, was collapsed, some scholars considered them to be made in North Song or early Southern Song Dynasties based only on the artistic style of sculptures of the grottoes. The School of Archaeology and Museology at Peking University recently carried out a survey documenting the Mingshansi Grottoes, and thereby the school gives an important material for studying the grottoes. The grottoes consist of a Dharma-protection Warrior niche, a statue of Guanyin and Dashizhi seated together, a standing Mahavairocana statue, a standing Manjushuri statue, a standing Wenshu and Puxian statue, a Turning Dharma-wheel pagoda (轉法輪塔 Zhuanfalunta) of Zhao Zhifeng, the founder of Liu Benzun sect. These statues are considered to be produced by an overall master plan in the Middle or Late Period of the Southern Song. The Shiku is believed to be a site at which Zhao Zhifeng performed some Buddhist rites such as Water and Land Rituals (水陸法會 Shuilufahui). Income of the ritual was also a major part of the funding for establishing large-scale Baoding Shiku at Dazu District, Chongqing City.

While artificial intelligence is rapidly replacing human jobs, the art field where human creativity is important is considered an exception. There are currently several AI mastering services in the field of mastering music, a profession at the border between art and technology. In general, the quality of AI mastering is considered to be inferior to the work of a human professional mastering engineer. In this paper, acoustic analysis, listening experiments, and expert interviews were conducted to compare AI and human experts. In the acoustic analysis, In the analysis of audio, there was no significant difference between the results of professional mastering engineers and the results of artificial intelligence. In the listening experiment, the non-musicians could not distinguish between the sound quality of the professional mastering engineer's work and the artificial intelligence work. The group of musicians showed a preference for a specific sound source, but the preference for a specific mastering did not appear significantly. In an expert interview, In expert interviews, respondents answered that there was no significant difference in quality between the two mastering services, and the biggest difference was the communication method between the mastering service provider and the user. In addition, as data increases, it is expected that artificial intelligence mastering will achieve rapid quality improvement and further improvement in communication.

The study was conducted to develop an effective forest resources use models for an alternate use of abandoned quarry by an attitude survey. According to the result of survey, a pessimistic view due to dust, noise pollution, and forest damage was 5% higher than an affirmative view by economic benefits from the development of quarry. The 42% of the respondents preferred the alternate use of abandoned quarry and the 25% of the respondents wanted an art and cultural space. The optimum size of alternate use was 5-10 ha (43%) with the requirement of nearby residents (32%). According to the SWOT analysis for abandoned quarry, the strength factors were an effective use of land, the content development of modern industrial inheritance + cultural and art fusion, attraction for nearby city and visitors, a harmony of beauty landscape and clean environment, and a sustainable increase of domestic and foreign visitors with the 5-day-work week. The opportunity factors were the improvement of traffic networks through KTX and local highway, the creation of the new growth engines with the establishment of artistic creation belts, the providing of unique cultural and art space through grafting of tour and education, the creation of local income through stone processed goods, and the vitalization of local development through eco-city. The weakness factors were a psychological remoteness and backwardness, and the weakness of staying tour infra. The threat factors were a poor financial support for sustainable development in nearby quarry and a modify of legal and institutional system for the alternated use of abandoned quarry. The developed restoration models for the alternate use in abandoned quarry are classified to a sculpture park, a waterfall and lake park, a rock-climbing, a sports park + forest park, a native botanical garden, a culture and art park, a complex park, a water storage site, a water storage site to extinguish forest fire, a geriatric hospital, an agricultural facility, and a school site types etc. The results suggest that the alternate use in the abandoned soil and stone quarry is needed to establish facility use models with consideration of user's preference.

The Petroglyph is a drawing on the rock which reflects the art, religion, myth, and life style of prehistoric society. Recently lots of researches have been studied to develop the contents applying the petroglyphs in the fields of exhibition, education, entertainment, and commercial. This research aims to find some possible VR contents based on the petroglyphs text. The review on the Ulsan petroglyph museum which is the first and the only petroglyph museum in Korea was the first step. Some limitation and problems were found in the current contents which could be overcome by using VR technology. The next step was the overall review of VR system and devices, and then I analyzed five cases of VR contents which specifically applied to the cultural heritages. Based on the analysis of case studies I propose some possible VR contents more immersive and interactive covered with whole range of petroglyphs context, environmental, social, cultural, technical and artistic.

These series articles were written in order to understand rockers of today and to provide basic data of their designs and manufacture studying pattern changes in the West. In the first article of the series reports we already described the theoretical background of rockers and the Windsor and the Boston style among the American classic rockers from the eighteenth to the twentieth century. This article contained the characteristics of the styles of the Shaker rocker, the Wicker rocker, and the Platform rocker. The three periods associated with furnituremaking in the Shaker sect are; the Primitive Era, which lasted from 1790 to 1820; the Classical Era, from 1820 to 1860; and the Final Phase, from 1860 to 1935. The important skills the Shaker needed to make the Shaker rocker are woodturning joinery, seat braid weaving and steam bending for the slats. The Wicker rocker continues to be extremely popular furniture style as the wicker proved equally effective for translating the ornate vine-like motifs popular among Art Nouveau proponents. The Wicker rockers were developed for child's, gentleman's and lady's, and it represents the most diverse forms among the above mentioned styles. However the rocker skates were often clumsy and took up too much room, preventing the chair from being shoved close to the wall and out of the way. These problems were overcome by the Platform rocker. The most important innovation was the technical development of a stationary base, which allowed the chair to rock noiselessly, without skating along the floor. The Modernism of the modern furnitures in America and Europe were affected by the characteristics of the Shaker rocker, the Wicker rocker, and the Platform rocker.

The Buddhist cave temple carved into the rock provides a large space for the ritual in general in which a structure of Stupa is built in the center of the space purely for religious worship empty of Sarira, and the temple is formed around this Stupa. Relief-Stupa of the cave temple indicates the similar shape that of Relief-religious worship of flat land temple. However, there appears a small difference in representation since the background of formation of the cave temple differs in that of flat land temple. Specially, Caitya Stupa of currently existing cave temples have been damaged to lose of their original shape only possible to be analyzed the stylistic development through Relief-Stupa from which the characteristic of Stupa could be understood. The early cave temple could be characterized with a balanced structure consists of upturn bowl, steeple stone with simple drum & Hamikawasnagae, in which it appears strongly the detail factor characteristics of drum & steeple of having system with Caitya Stupa. In the post cave temple, the subject of worship moved to statue of Buddha due to the influence of Gandhara, Mathura art which reduced the importance of Stupa. This illustrates in Relief-stupa as well the style change as well as changes in detail factor. The sculpture appeared at the limited location either the wall of Caitya shrine or pillar in vihara cave with stronger decorative meaning. Contrast to the Relief Stupa of early flat land temples or the cave temples mentioned above sculptured with symbolism, however, the post cave temple showed the relief structure based on the plan of flat plan.

The guarantee of the performance of the engineered barriers in a geological repository is very important for the long-term safety of disposal as well as the efficient design of the repository. Therefore, the performance of the engineered barriers under repository condition should be demonstrated by in-situ experiments conducted in an underground research laboratory. This article provides a review of the major in-situ experiments that have been carried out over the past several decades at underground research laboratories around the world to validate the performance of engineered barriers of a repository, as well as their results. In-situ experiments to study the coupled thermal-hydraulic-mechanical behavior of the engineered barrier system used to simulate the post-closure performance of the repository are analyzed as a priority. In addition, in-situ experiments to investigate the performance of the buffer material under a real repository environment have been reviewed. State-of-the art in-situ validations of the buffer-concrete interaction, and the installation of the buffer, backfill and plug, as well as characterization of the near-field rock and the corrosion of the canister materials are, also performed.

X-ray computed tomography (CT) is very useful for the quantitative evaluation of internal structures, particularly defects in rock samples, such as pores and fractures. In situ CT allows 3D imaging of a sample subjected to various external treatments such as loading and therefore enables observation of changes that occur during the loading process. We reviewed state-of-the-art of in situ CT applications for geomaterials. Two triaxial cells made using relatively low density but high strength materials were developed aimed at in situ CT scanning during hydro-mechanical laboratory testing of rocks. Preliminary results for in situ CT imaging of granite and sandstone samples with diameters ranging from 25 mm to 50 mm show a resolution range of 34~105 ㎛ per pixel pitch, indicating the feasibility of in situ CT observations for internal structural changes in rocks at the micrometer scale. Potassium iodide solution was found to improve the image contrast, and can be used as an injection fluid for hydro-mechanical testing combined with in situ CT scanning.
