Cheommojik is a pile cloth, a type of textile whose surface is covered with short piles. The term chaedam was used during the late Joseon dynasty to refer to pile cloth rugs, while the terms yoongjeon, dantong and yangtanja were used in the early twentieth century. Various documents, newspaper articles and photographs confirm that pile cloth rugs were used by the general public as well as the royal family from the late Joseon dynasty onward, and that there were domestic manufacturers of such rugs at that time. This study investigated six pile cloth rugs that were produced after the late Joseon dynasty, five of which feature Persian knots made of cut pile, the other being made with the loop pile method. The cut pile rugs are rectangular in shape and measure between 72-98cm by 150-156cm; and they are decorated in the middle with patterns of butterfly, deer, and tiger or the ten longevity symbols, and along the edges with patterns composed of 卍 symbols. The ground warp of all six rugs are made from cotton yarn, while the ground weft is made of cotton yarn on three pieces, wool on one piece and cotton and viscose rayon. The ground weft yarn from four pieces are Z-twist yarn made with two or more S-twist cotton yarn. Four to six colors were used for the pile weft, all being natural colors except for red. Two or more S- or Z-twist yarn were twisted together in the opposite twist for the pile weft, with the thickness determining the number of threads used. Six or more weft threads were used to make the start and end points of the rug; and the ground warp ends were arranged by tying every four of them together. For the left and right edges, three or more threads were wrapped together into a round stick-like form, and the second and third inner ground warps from the edges were stitched on to the wrapped edge. For the loop pile, loops were made in the direction of the warp; the ground warp and the ground weft may have been made with cotton, the pile warp with wool yarn. An analysis of the components of three rugs was conducted to determine which types of animal hair were used for the pile weft. Despite some inconclusive results, it was revealed that goat hair and fat-tailed sheep hair were used, raising the possibility that various kinds of animal fur were used in the production of pile cloth rugs. The six rugs examined in this study are estimated to have been made between the late 1800s and the early 1900s. Although the manufacturer of the rugs cannot be confirmed, we concluded that the rugs were produced in Korea after referring to the documentation of the domestic production of pile cloth rugs during the aforementioned period and the form and placements of the patterns on the rugs.

A spirit tablet of king Guan Yu is enshrined in Donggwanwangmyo shrine[East Shrine of King Guan Yu], which houses 51 hanging boards. The hanging boards were written by the kings of Joseon Dynasty and envoys and generals of the Ming and Qing Dynasties. Most studies on hanging boards have been focused on the collections of the palaces but not on those in Donggwanwangmyo shrine. In this regard, this study researches the hanging boards of the kings' writings in the late Joseon period and analyzes their forms and contents. In terms of contents, it examines who made the boards, when they made them, and what brought them to make them, etc. This study analyzes the forms of hanging boards by types, used materials, and periodic transition of forms. The findings are as follows. First, Donggwanwangmyo shrine houses 7 pieces of hanging boards inscribed with kings' handwriting: one piece of King Sukjong, 4 pieces of King Yeongjo, and 2 pieces of Emperor Gojong. They are divided into two types: one is the name of the buildings and the other is the poems that the kings wrote regarding what they felt when they visited the shrine. Especially, the latter were written by the kings who visited the shrine in spring and autumn. The kings intended to promote peace of royal family through a sense of royalty and fidelity of King Guan Yu. Second, the hanging boards of the kings are differentiated from those of the envoys and generals of the Ming and Qing Dynasties in materials and forms. The background of the board is colored by blue, deep red lacquer color, and black lacquer color, which are more expensive than black color or white color. The hanging boards are embossed with the kings' handwritings and then colored with gold. The frame-style four-side hanging board is held at a 45-degree angle and painted with floral patterns and seven-treasure patterns in Dancheong technique. The left and right sides and the top and bottom sides of the board are decorated with Dang-cho pattern(Korean arabesque pattern). This style is called "quadrilateral"and considered the most classy and top-class among the other three ones. In conclusion, this study confirms the status of Donggwanwangmyo shrine with hanging boards inscribed with kings' handwritings as a political space where kings had interest and demanded their soldiers' royalty and fidelity. Research into the boards inscribed with the handwritings of envoys of the Ming Dynasty and generals of the Qing Dynasty, and the comparison of the styles and periodic transition of forms will be reserved for another study.

From the cosmopolitan superiority of the as the first world map completed in 1402 with surprisingly detailed images and contents on the Africa Continent it is reasonable to think that the Koreans in early fifteen century were already with highly up-to-date perspectives on the universe and world history and cultures. However, some 490 year later the first phytohydrographic plankton investigation in the neritic seas of Korea was performed by a Japanese company with sampling points covering from Tokyo Bay through Jeju neritic waters to Shanghai estuary, which was in turn preceded by the first oceanographic investigation other than the simple mapping Koreans seas by using two French sailboats. The first phytohydrographic plankton investigation in Korean seas were behind the world first oceanic plankton exploration, the German Plankton Expedition, by 25 years. Starting from the oceanographic investigation including phytohydrographic samplings in the whole Yellow Sea in 1915 the full-scale phytohydrographic plankton studies were tried in Korean seas which is well represented by the 1921 oceanographic investigation on the whole East Sea with 80 sampling stations. In 1932 two separate oceanographic investigations followed, one in the East Sea where 78 stations from Busan to southern Sakhalin Island were simultaneously visited by 50 research vessels for the physical, chemical, and biological oceanographic studies, and the other one in southern coast and western East Sea of Korea where ocean current observation as well as plankton sampling were made in 120 stations to understand the relationship between the ocean current and plankton distribution in the region. In 1933-1934 more intensified investigations on phytohydrography were carried out particularly in the East Sea as an integral part of the basic marine ecosystem studies for the Myeong-Tae (Alaska Pollock) resources estimation. Scientists' attitude for the marine investigation and research activities seemed to be almost unchanging even to the year 1943, which could be reflected by the fact that publication of the results from the investigations performed in 1945 were finally done in 1967 at Tokyo. Some 70 years later from the mid-twenty century we might be standing on the turning-point of "need to be prepared" for the new era of changing paradigm by reviewing, archiving, and analyzing the prior information big data from the previous ocean observation and biohydrographic investigations. At the same time each professional societies for the above mentioned sciences might trigger a continuous project to reorganize and update the records on related bibliography and its history every 30 years.

Buddhism, which was subject to repression all over the early Joseon Dynasty, received a certain recognition from the state, because Buddhist monks had participated in the war of the Japanese invasion in 1592. On the other hand, however, one of the results was the destruction of many temples. In the late Joseon Dynasty, the Buddhist monks themselves acted as players of Pungmul(people's percussive band music) for the rebuilding of Buddhist temples. These so-called "the Buddhist monks' Pungmul" is the imitation of former clowns' Pungmul and farmers' one that sometimes request money or rice at houses of villages. In the late Joseon Dynasty, the activities of the Buddhist monks' Pungmul were held all over the country. Today, there are "Bitnae Nongak(farmers'percussive band music)" in Kyeongsangbuk-do, "Beokku-noli(the drum play) in the areas of Yeosu and Gangjin in Jeollanam-do, the song of the Buddhist monks' Pungmul for the people's house spirits in the Gyeonggi-do, Gangwon-do and Chungcheong-do, and Namsadang-pae(the nomadic entertaining groups composed of only men), as clear pictures of it. In these things related to Nongak or Nongak relevant affairs, the shapes of the Buddhist monks' Pungmul in the late Joseon Dynasty remain clear. On the other hand, today the Namsadang-pae, which was formed as a result of Buddhist monks' Pungmul in the late Joseon Dynasty, was left only in the Chungcheong-do and Gyeonggi-do, because the temple construction in the Gyeonggi-do was made especially many in the late Joseon Dynasty. During the late Joseon Dynasty, the Buddhist monks' Pungmul, which had long-lived and had taken place throughout the nation, had a great impact on Pungmul. There are the Buddhist elements, such as Gokkal(the Buddhist monk's peaked hat), paper flowers, the color band, the small drum, and Bara(small cymbals) are often found in the Pungmul of Korea. In the late period of the Joseon Dynasty, it is obviously important place in the Pungmul history of Korea. Research and studies on this subject should be made more in the future.

The concept of denied boarding is defined in Article 2(j) of Regulation 261/2004 thus: "denied boarding means a refusal to carry passengers on a flight, although they have presented themselves for boarding under the conditions laid down in Article 3(2), except where there are reasonable grounds to deny them boarding, such as reasons of health, safety or security, or inadequate travel documentation." So far as relevant to this case, to be entitled to compensation, if denied boarding, Article 3(2) provides a passenger must first come within the scope of the protection of the Regulation, which applies under the following conditions: "${\cdots}$.that passengers (a) have a confirmed reservation on the flight concerned and, except in the case of cancellation referred to in Article 5, present themselves for check-in, as stipulated and at the time indicated in advance and in writing (including by electronic means) by the air carrier, the tour operator or an authorised travel agent, or, if no time is indicated, not later than 45 minutes before the published departure time." This paper reviews the EU Cases such as Rodríguez Cachafeiro v. Iberia [2012] Case C-321/11; Finnair Oyj v. Timy Lassooy [2012] Case C-22/11; Caldwell v. easyJet Airline Co. Ltd. [2015] ScotSC 64. ECJ and Sheriff court of Scotland held that the concept of denied boarding, within the meaning of Articles 2(j) and 4 of Regulation No 261/2004 establishing common rules on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights, and repealing Regulation No 295/91, must be interpreted as relating not only to cases where boarding is denied because of overbooking but also to those where boarding is denied on other grounds, such as operational reasons. Also, ECJ ruled that Articles 2(j) and 4(3) must be interpreted as meaning that the occurrence of extraordinary circumstances resulting in an air carrier rescheduling flights after those circumstances arose cannot give grounds for denying boarding on those later flights or for exempting that carrier from its obligation, under Article 4(3) of that regulation, to compensate a passenger to whom it denies boarding on such a flight.

Space Treaty Article 2 stipuates non-appropriation by sovereignty, and in any other means. Interpretative controversies has continued as regards the meaning of any other means. It is not clear whether appropriation by private entity is also prohibited or not. Furthermore, the controverse around the binding force of Article 1 has made worse the controversy regarding such appropriation. U.S. Congress has enacted the law regarding the space resouce mining in 2015. Its main purpose is to alleviate legal unstability which U.S, private companies have faced, and it provides some provisions regarding private rights about space resources. Original bill, H.R. 1508 included the property right. Amendment to the bill is to ensure that an "asteroid resource utilization activity" is inter-preted as on a single asteroid and not on any asteroid. The use of the word "in situ" in defining space resources simply means resources in place in outer space; but any such resource within or on an asteroid would need to be "obtained" in order to confer a property right. The use of the word "in situ" in merely defining a space resource in the bill is not equivalent to claiming sovereignty or control over celestial bodies or portions of space. Further, there is clear Congressional direction in the bill that the President is only to encourage space resources exploration and utilization, including lowering barriers to such activity, "consistent with" and "in accordance with" US international obligations. Federal courts are granted original jurisdiction over entities defined in ${\S}$ 51301(4) and in-situ asteroid resources that have been removed from an asteroid by such entities. Federal courts are not granted jurisdiction over outer space, the Moon, other celestial bodies, or the asteroid from which the in-situ natural resource was removed. It is said that the Space Resource Utilization Exploration Act of 2015, talked about the rights of private players to own-kind of a "finders keepers" law.

In this study, we carry out the numerical simulation to trace the yearly shoreline change of Mang-Bang beach, which is suffering from erosion problem. We obtain the basic equation (One Line Model for shoreline) for the numerical simulation by assuming that the amount of shoreline retreat or advance is balanced by the net influx of longshore and cross-shore sediment into the unit discretized shoreline segment. In doing so, the energy flux model for the longshore sediment transport rate is also evoked. For the case of cross sediment transport, the modified Bailard's model (1981) by Cho and Kim (2019) is utilized. At each time step of the numerical simulation, we adjust a closure depth according to pertinent wave conditions based on the Hallermeier's analytical model (1978) having its roots on the Shield's parameter. Numerical results show that from 2017.4.26 to 2017.10.15 during which swells are prevailing, a shoreline advances due to the sustained supply of cross-shore sediment. It is also shown that a shoreline temporarily retreats due to the erosion by the yearly highest waves sequentially occurring from mid-October to the end of October, and is followed by gradual recovery of shoreline as high waves subdue and swells prevail. It is worth mentioning that great yearly circulation of shoreline completes when a shoreline retreats due to the erosion by the higher waves occurring from mid-March to the end of March. The great yearly circulation of shoreline mentioned above can also be found in the measured locations of shoreline on 2017.4.5, 2017.9.7, 2017.11.7, 2018.3.14. However, numerically simulated amount of shoreline retreat or advance is more significant than the physically measured one, and it should be noted that these discrepancies become more substantial for the case of RUN II where a closure depth is sustained to be as in the most morphology models like the Genesis (Hanson and Kraus, 1989).

Proanthocyanidins are naturally occurring polyphenolic compounds abundant in many vegetables, plant skins (rind/bark), seeds, flowers, fruits, and nuts. Numerous in vitro and in vivo studies have demonstrated myriad effects potentially beneficial to human health, such as antioxidation, immunomodulation, DNA repair, and antitumor activity. Among immune cells, macrophages are crucial players in a variety of inflammatory responses to environmental conditions. However, it has been widely reported that macrophages cause chronic inflammation and are involved in a variety of diseases, such as obesity, diabetes, metabolic syndrome, and cancer. In this study, we report the suppressive effect of proanthocyanidins via the heme oxygenase-1 (HO-1)-related system, on the immune response of the LPS-stimulated mouse macrophage cell line RAW264.7. Increased HO-1 expression at mRNA and protein levels were found in proanthocyanidins-treated RAW264.7 cells. Further, proanthocyanidins enhanced nuclear factor-erythroid 2-related factor 2 translocation into the nucleus. RAW264.7 cells were treated with lipopolysaccharide (LPS) with or without proanthocyanidins, and inflammatory mediator expression levels were assessed. Proanthocyanidins treatment resulted in the attenuation of nitric oxide production and inducible nitric oxide synthase expression in LPS-stimulated RAW264.7 cells. In addition, mRNA and protein expression of proinflammatory cytokines, such as tumor necrosis factor-${\alpha}$ and interleukin-6, was inhibited by proanthocyanidins treatment in LPS-stimulated RAW264.7 cells. These findings support proanthocyanidins as a promising anti-inflammatory agent.

We will study cultural sprauchling about Pungmul-Kut to find out the sphere of "Gui-myeong-gui" alongside Jeollanam-do, Jeollabuk-do western coast. In this area, there are some traits and terms about Gui-myeong-gui, a sort of Pungmul-Kut and Goon-go. Several Pungmul-Kuts which border the sphere of Gui-myeong-gui are Goon-gui in a southern direction, Unnyeongnongak of Honamudonongak in a eartern direction, and Yeongmujangnongak. The acculturation occurs in two ways. One is the possible acculturation with Goon-gi or Goon-go in coastal areas. The other is the acculturation with Honamudonongak. Especially, this phenomenan appears in double-way interaction. At first, there is the influence of Gui-myeong-gui in Honamudonongak. Kim Bau's style, which might relate to Gui-myeong-gui in Geommopojin, incorporate one of Panje of Honamudonongak through Park Namsik. This phenomenon is porved by the affinity between Eunjijaetji Galag of Honamudonongak GeollibKut and Eungmagaenggaeng Galag of Goon-go, and by the similarity to Neonari-Galag. In case of Neonari-Galag, the role of Jing in Neonari-Galag is replaced by Janggu in Honamudonongak, because of the geatest popularity of Janggu in those days. Secondly, there is the influence of Honamudonongak in Gui-myeong-gui. Northern sphere of Gui-myeong-gui like Buan-gun, Okgu-gun has been influenced since early $20^{th}$ century. In addition, the phenomenon which the sphere of Gui-myeong-gui accepts actively Honamudonongak could occur. So this thesis fragmentarilly checks the existence and traits of Gui-myeong-gui. Based on it, we would be able to reveal and reconstitute the nature of Gui-myeong-gui by understanding acculturation of Pungmul-Kut and by comparing Goon-go with Honamudonongak and Yeongmujangnongak in several regions. Also this thesis draws attention about meanings and effects of Yeonhuinongak's acceptace of Goon-beop.

This study presents a review on the recent climate change over the Korean peninsula, which has experienced a significant change due to the human-induced global warming more strongly than other regions. The recent measurement of carbon dioxide concentrations over the Korean peninsula shows a faster rise than the global average, and the increasing trend in surface temperature over this region is much larger than the global mean trend. Recent observational studies reporting the weakened cold extremes and intensified warm extremes over the region support consistently the increase of mean temperature. Surface vegetation greenness in spring has also progressed relatively more quickly. Summer precipitation over the Korean peninsula has increased by about 15% since 1990 compared to the previous period. This was mainly due to an increase in August. On the other hand, a slight decrease in the precipitation (about 5%) during Changma period (rainy season of the East Asian summer monsoon), was observed. The heavy rainfall amounts exhibit an increasing trend particularly since the late 1970s, and a consecutive dry-day has also increased primarily over the southern area. This indicates that the duration of precipitation events has shortened, while their intensity became stronger. During the past decades, there have been more stronger typhoons affecting the Korean peninsula with landing more preferentially over the southeastern area. Meanwhile, the urbanization effect is likely to contribute to the rapid warming, explaining about 28% of total temperature increase during the past 55 years. The impact of El Nino on seasonal climate over the Korean peninsula has been well established - winter [summer] temperatures was generally higher [lower] than normal, and summer rainfall tends to increase during El-Nino years. It is suggested that more frequent occurrence of the 'central-Pacific El-Nino' during recent decades may have induced warmer summer and fall over the Korean peninsula. In short, detection and attribution studies provided fundamental information that needed to construct more reliable projections of future climate changes, and therefore more comprehensive researches are required for better understanding of past climate variations.
