Buddhist articles from various periods in the Vairochana Buddha statues, which are currently housed in the Haeinsa Temple's Supreme Buddha Hall and Beopbojeon Hall. This research concentrates on the artifacts found inside the storage boxes, which was placed inside the Buddha statues in 1490. A total of 24 pieces of fabric articles found inside the Virochana Buddha in Beopbojeon and 213 pieces from the Supreme Buddha Hall were examined. The types of textiles are as follows: bast fiber, silk, cotton, and union cloth. Bast fiber consisted of ramie and hemp. For silk, tabby woven with plain weave, spun silk, and thin tabby were found. And twill damask made with twill, Sa and Ra with the leno weave, and satin damask made with the satin weave were also found. Also the two Jeogoris and three Jogakbos were found, the one Jeogori was made with Hwan. The Buddhist articles in the Vairochana Buddha of Haeinsa have been preserved well and its colors have remained virtually the same from the time of its original placement. Therefore these articles are very important in understanding the textile characteristics, weaving techniques, dying techniques as well as traditional colors.

The objective of this study was to determine the effect of moisture contents (40, 50, 60%) and $CO_2$ gas injection (0 and 800 mL/min) on physicochemical properties of extruded soy protein isolate (SPI). The expansion ratio and the specific length increased, but piece density decreased with the increase in $CO_2$ gas injection from 0 to 800 mL/min at both 40 and 50% moisture contents. On the contrary, the expansion ratio and the specific length decreased, but piece density increased with the increase in $CO_2$ gas injection from 0 to 800 mL/min at 60% moisture content. Extruded SPI with $CO_2$ gas injection at 800 mL/min had small cell size and higher amount of cell than extruded SPI without $CO_2$ gas injection. The water holding capacity and nitrogen solubility index increased, and the integrity index and the texture decreased with the increase in $CO_2$ gas injection from 0 to 800 mL/min. In conclusion, extruded SPI with the $CO_2$ gas injection at 800 mL/min showed better expansion properties and cell formation than extruded SPI without the $CO_2$ gas injection.

In this study, small bird tracks from the Cretaceous Sanbukdong Formation in Gunsan City, South Korea, were briefly described. Detrital zircon SHRIMP U-Pb dating was conducted of the tuffaceous sandstone from the formation to determine the depositional age of the vertebrate track-bearing strata. Small bird tracks are not well-preserved but divided into two types: two consecutive tracks and three isolated tracks. They are small, asymmetric, slender, functionally-tridactyl tracks, which lack a web between digits. The consecutive and isolated tracks were identified as Koreanaornis dodsoni? and Koreanaornis ichnosp., respectively. This study adds avian tracks to the Sanbukdong tetrapod track assemblage composed of theropods, ornithopods, and pterosaur tracks. According to the U-Pb dating, the estimated age of the Sanbukdong Formation is 112.5±5.8 Ma, regard as the Aptian Stage, representing the maximum depositional age for the Sanbukdong Formation. The Sanbukdong Formation can be correlated with the lower part of the Jinju Formation in the Gyeongsang Basin. Thus, small avian tracks may represent the oldest Korean occurrence of Koreanaornis.

The tracksite of dinosaurs and pterosaurs in Sanbuk-dong of Gunsan is the largest early Cretaceous dinosaur footprint fossil site in Korea, and all the footprints are important evidence indicating that large ornithopod and theropod dinosaurs inhabited the Korean peninsula during the early Cretaceous. The Sanbuk-dong site was covered with waterproof sheet in an outdoor environment until the installation of a protective enclosure in 2021. As a result, various factors such as shear force, load reduction, temperature and humidity fluctuations, acid rain, salinity and microorganisms have complexly interacted in the substrate of fossils, exacerbating the damage to footprints. For 159 footprints in 12 trackways among the footprints found in the site, the damage types were classified in detail and the level of each damage was assessed. The damages were classified into 6 types through the classification of deterioration degree of individual footprints. As a result of ultrasonic physical property evaluation on the surface of the fossil site, most of these footprints are in the completely weathered (CW) stage. Furthermore, various weathering patterns were observed in the study area, and surface contaminants were analyzed along the stratigraphy. Although the patterns of freshness and contaminants varied at different points within the fossil site, the chemical compositions were similar. Based on the results, an efficient conservation management system for dinosaur footprint fossils was established, and a conservation treatment type for each footprint was proposed.

This paper explores rich and complex implications of Marcel Duchamp's Mile of String which he created for "First Papers of Surrealism," the Surrealist international exhibition in New York in 1942. Part of a larger project devoted to investigating Duchamp's role in Surrealist exhibitions and his relation to the avant-garde group, this paper focuses on Duchamp's exhibition installation in the 1942 show. Under the title of "g$\acute{e}$n$\acute{e}$rateur-arbitre" Duchamp played an important role as installation and exhibition designer in a series of major Surrealist exhibitions in the 1930's-1960's. The "First Papers of Surrealism" was held by Surrealists who exiled in New York during World War I, and Duchamp created a labyrinthine installation of string for the exhibition, which physically blocked the spectator and optically hindered his or her contemplative view. Unraveling the intricately related meanings of Mile of String as an independent work of art and an installation for a specific exhibition, I examine the work on two levels: first, how the work was situated in the context of Duchamp's oeuvre, particularly his earlier work employing string or thread; second, how and in what way the installation rendered a critique on Surrealism as a group and an avant-garde movement. More specifically, by exploring the concepts of 'pataphysics' and voluntary 'nomadism' implicated in Duchamp's work, I suggest that his Mile of String asserted a critical stance against nationalism and collective identity of Surrealism and manifested a radical individualism founded upon what he called the spirit of 'expatriation.'

Characteristics of biological data including genome sequences are heterogeneous and various. Although the need of management systems for genome sequencing which should reflect biological characteristics has been raised, most current biological databases provide restricted function as repositories for biological data. Therefore, this paper describes a management system of nucleotide sequences at the level of biological laboratories. It includes format transformation, editing, storing and retrieval for collected nucleotide sequences from public databases, and handles sequence produced by experiments. It uses BSML based on XML as a common format in order to extract data fields and transfer heterogeneous sequence formats. To manage sequences and their changes, version management system for originated DNA is required so as to detect transformed new sequencing appearance and trigger database update. Our experimental results show that applying active trigger rules to manage changes of sequences can automatically store changes of sequences into databases.

Microplastics are fragments of any type of plastic with a size less than 5 mm. Ocean pollution by microplastics is now a worldwide concern in relation to marine ecosystems and human health. The widespread contamination by microplastics means that they can be ingested by and accumulated in diverse species of wildlife, such as fish, mussels, oysters, clams, and scallops. Once ingested, the microplastics can be observed in the intestines, liver, and kidney, and even in the brain. Seafood is one of the major sources of protein intake in humans; therefore, seafood consumption could be pathway for human microplastics exposure. Accumulating evidence indicates that repeated oral exposure to microplastics induces pathologic and functional changes in the reproductive, cardiac, gastrointestinal, endocrine, and even nervous systems of rodents. Maternal exposure to microplastics during gestation and lactation alters metabolic homeostasis in the offspring. Given that seafood provides more than 20% of the total protein intake by over 310 million people worldwide, a reasonable assumption is that microplastics could be substantially accumulated in the human body and impair physiological function. In this review, we have summarized the current status of microplastics contamination in the ocean, their accumulation and toxicities in marine animals and rodents, their exposure to humans, and their potential impacts on human health.

The Dinosaur tracksite at Jeori, Geumseongmyeon, Euiseonggun, Gyeongsangbukdo, Korea (National Monument No. 373) has been studied in the aspects of location, stratigraphy, sedimentology, fossil occurrence, unique geological records, literature, significance in natural history, preservation, and management. On the basis of these features, the Jeori tracksite has been assessed semiquantitavely. The Jeori tracksite occurs in the Sagok Formation (Albian) of the Euiseong sub-basin, and over 300 footprints forming 12 sauropod trackways, 10 ornithopod trackways, and 1 theropod trackways are preserved in this tracksite. The track-bearing deposits consist of tabular-bedded medium- to fine-grained arkose with mudstone drape, interlaminated fine-grained sandstone to siltstone and mudstone, and shaly mudstone. The dinosaur tracks are preserved in the interlaminated fine-grained sandstone to siltstone and mudstone, and most of them are observed as underprints. The track-bearing deposits are interpreted as sheetflood deposits on the floodplain under a seasonal paleoclimatic condition with alternating of wetting and drying periods. Multiple tension fractures with NE strike were formed in the track-bearing bed, which resulted in that tracks seem to occur in several horizons. The significance in natural history of the tracksite can be summarized as follows: 1) the historical implication of the Jeori tracksite as the firstly designated National Monument of dinosaur fossil sites, 2) the high density of the occurrence of diverse footprints (over 300) within small area (about $1,600m^2$), and 3) the significance of the tension fractures associated with the track-bearing bed as geoeducational records for the understanding the development of fault. In order to share the value of the Jeori tracksite in the aspect of natural history with the community and public, the interpretive panel should be modified to include figures explaining paleoenvironment and tension fault development. In addition it is recommended that a brochure be published briefly explaining the tracksite and to educate the residents about the natural and social significance of the tracksite. For the safety of visitors it would be desirable for the road in front of the tracksite to be moved at least 10 m southward, which could mitigate the shaking of the track bed caused by traffic.
