A moat is a pond or waterway paved on the outside of a fortress that is one of the facilities to prevent enemy from approaching the fortress wall or classify it as the boundary space, moats had existed in Europe, Asia and the America from ancient times to medieval times. however it is has been disappeared in modem society. In addition, a moat is a great value in historical and cultural sense such as offering a variety of cultural activities and habitats for animals, but unfortunately there is little consideration of its restoration plan. This research is aimed to investigate historical and cultural meaning and significance of moats which had been existing from ancient times to medieval times in the Eastern and Western. For this purpose, this research analyzed concepts and functions in consideration with times and ideological backgrounds of moats in Korea, China, and Japan. Results were as follows: 1. Moats in Korea existed not only in the castle towns of Goguryeo but also in ancient castle towns of Baekje and Silla. Natural moats and artificial moats existed around castles that were built to prevent and disconnect accessibility of enemies In Goryeo Dynasty and Chosun Dynasty, moats were also used as a defensive function. 2. A moat was generally installed by digging in the ground deep and wide at regular intervals from the ramparts, A moat was installed not only around a castle but also in its interiors. Moats outside castles played an important role in stomping the ground hard besides enhancing its defensive power. In addition, water bodies around a facility often discouraged people's access and walls or fences segregated space physically, but a moat with its open space had an alert and defensive means while pertaining its visual characteristics. 3. The moat found at Nagan Eupseong rumor has it that a village officials' strength was extremely tough due to strong energy of the blue dragon[Dongcheon] in Pungsujiri aspects, so such worries could be eliminated by letting the stream of the blue dragon flow in the form of 'S'. 4. The rampart of the Forbidden City of China is 7.9 meters high, and 3,428 meters long in circumference. It was built with 15 layers of bricks which were tamped down after being mixed with glutinous rice and earth, so it is really solid. The moat of the Forbidden City is 52 meters in width and 6 meters in depth, which surrounds the rampart of the Forbidden City, possibly blocking off enemies' approach. 5. Japan moats functioned as waterways due to their location in cities, further, with the arrangement of leisure facilities nearby, such as boating, fishing from boats, and restaurants, it helped relieve city dwellers' stress and functions as a lively city space. 6. Korean moats are smaller in scale than those of the Forbidden City of China, and Edo, and Osaka castles in Japan, Moats were mostly installed to protect royal palaces or castles in the Eastern Asia whereas moats were installed to protect kings, lords, or properties of wealthy people in the west.

In this text, the author examines the aspects and characteristics of the three forms that were created and enjoyed when the upper-class nobles of Japan "combined(混淆)" waka(和歌) and Chinese poetry(漢詩) between the 10th and 17th centuries. The three forms are the "Collection of Japanese and Chinese poems for singing"(和漢朗詠), "A collection of Japanese and Chinese poems" (詩歌合), and the "Renku renga"(聯句連歌). "Collection of Japanese and Chinese poems for singing" appeared in the 10th century, "A collection of Japanese and Chinese poems" appeared in the 12th century, "Renku renga" appeared in the 14th century, and all three continued to influence the history of Japanese literature after that time. As the combination of literary Japanese and Chinese progressed, the gap between waka and Chinese poetry decreased until they finally combined to create a single work. That is, waka and Chinese poetry converged in one place in multiple ways: as a work that was appropriate to be recited("Collection of Japanese and Chinese poems for singing"), facing each other work against work in a competition("A collection of Japanese and Chinese poems"), and, in the end, they reached the point where they were interchangeable as lines making up long poems(長詩)("Renku renga"). The combination of literary Japanese and Chinese can be said to be the Japanese version of the common movement in East Asian literary history during the Middle Ages to make songs from one's own language flawless in Chinese poetry. Meanwhile, by examining the status changes that appeared as Chinese poetry paralleled, fought with, replaced, and combined with waka, we can find clues to explain the attitudes of the Japanese people on Chinese poetry during the period when the three forms existed, as well as the characteristics of Japanese Chinese poetry that appeared in response to that. The preferences not of "myself" but of the "audience," content and expressions that revere the period rather than the inner self of the poet, and the fact that it is a means for enjoyable pleasure rather than having the original characteristics of lyrical poetry for self-expression are all characteristics of Chinese poetry in Japan during the early and late Middle Ages period. These characteristics can be said to be the current that flows in the underbelly of the history of Chinese literature in Japan. This author believes that the key to discussing the history of Chinese literature in Japan during the Middle Ages period from the perspective of East Asian literary history can be found here.

Activated carbons prepared by chemical activation of organic waste sludges with $ZnCl_2$ and $K_2S$ have been studied in terms of their pore development and adsorptivity. Pore development of the carbons prepared from organic waste sludges was characterized by the nitrogen adsorption at 77K. The $ZnCl_2$-activated carbon produced by chemical activation with zinc chloride exhibited type I isotherm characteristics according to the BDDT classification, suggesting the presence of micropores formed by activation process. The isotherms of the commercial powdered activated carbon and $K_2S$-activated carbon reveal a hysteresis similar to that of type IV in BDDT classification, indicating the formation of mesopores. This result implies that the major pores of $K_2S$-activated carbon are composed of meso and micropores, and a macropores are minor. The adsorptive capacities of metal on the $K_2S$-activated carbon prepared from organic waste sludges were found to be superior to those on a commercial granular activated carbon. The Langmuir and Freundlich isotherms yield a fairly good fit to the adsorption data, indicating a monolayer adsorption of metals onto $K_2S$-activated carbon. The adsorptive capacity of the $K_2S$-activated carbon was superior to $ZnCl_2$-activated carbon for $PO_4$-P, and vice versa for $NO_3$-N. From the results of the studies reported here, it can be concluded that activated carbons with adsorptivity superior to commercial granular activated carbons can be produced from organic waste sludge using a two-step carbonization/activation procedure with zinc chloride or potassium sulfide as the activating agents.

From the perspectives of grammaticalization and corpus, the purpose of this study is to examine the motivation of the emergence of the split infinitives in American English and to discuss the justification of the split infinitives based on the corpus empirical data such as COHA and COCA. The formerly ungrammatical split infinitives in the form of [to + adverb + verb] are now definitely grammatical forms in Present Day English (PDE). The corpus-based data confirms the legitimacy of the split infinitives with the empirical reasons like clarifying sentences (i.e., disambiguation) or strongly focused readings. In addition, the split infinitives are natural consequences caused by the grammaticalization of an infinitival particle to and most crucially by the loss of verb movement. When verb movement to T position does not occur in infinitival clauses, the word order results in [to + AdvP + V], thus forming the split infinitives. The split infinitives are no longer a matter of discussion and will continue to increase in both formal and informal contexts as being definitely grammatical forms.

This study was carried out to find out the difference of ripening and growth characteristics among the different florets in same panicle. There were 2 different transplanting date (May 25 and June 10) and 6 varieties were used. Physiological ripening period, ripening speed, 1000 grain weight, germination speed and grain quality were studied among the different florets (1, 5 and 8 days after heading) in same panicle. Physiological ripening period was long in late transplanting, late flowering floret, and late varieties by 3-9 days in Japonica. Ripening speed and 1000 grain weight were high in early transplanting and early flowering florets. There was positive correlation among the ripening speed, 1000 grain weight and a average temperature but negative correlation between the ripening and physiological ripening period. Germination speed was excellent in early flowering floret after heading. There was difference in amylose content within varieties and different flowering grains and there was significant correlation between grain quality and meteorological factors in some varieties.

This thesis investigates the cultural meanings of the first optical instrument, Camera obscura, in the pre-modern age, while it explains the development as well as the use of the Camera obscura in Europe and Korea. For this purpose the thesis traces the significant phases of the historical developments of the Camera obscura from L. da Vinci, G. B. della Porta, D. Barbaro, A. Kircher to J. Zahn etc. The Camera obscura was not only the symbolic instrument of the modernism in the sense that human being wanted to observe the outer world by himself and to be freed from the viewpoint of the christianity, but also was the forerunner of the modern visual culture, because it first time reproduced the artificial image of the natural world. Since the second half of the 17th century the box-type reflex Camera obscura had been produced, it began to be used as aid to drawing for painters like J. Vermeer, A. Canaletto and J. Reynolds etc. throughout Europe. It tells the evidence of the close relation between art and technology in the pre-modern age. Around the end of the 18th century the Camera obscura was brought to Korea, the closed country of the Fareast, by the scholars of the so-called 'Realist school' (Silhak-pa) who went to Beijing to acquire knowledges on the Western science from the European priests. In 1780s Yak-yong JUNG, one of the representative scholars of the Realist school, experimented the Camera obscura, and then, it was used for sketches of higher aristocrats' portraits by the supreme portrait painter of that time, Myoung-ki LEE. Those were possible only under the reign of the culturally liberal and reformative King, Jung-jo (ruled 1776-1800), and after his retreatment the inquiry of the Camera obscura had been dimished. It is not a historical coincidence that the Camera obscura could be examined and used in the period of the Enlightment both in Europe and Korea.

Arbitration is a just and efficient method for resolving economic disputes. It adapts to the needs of economic development and is an important institution in today's society. Around the world, a tradition of resolving disputes through arbitration spontaneously developed in ancient times and gradually evolved into a legal system with the development of jurisprudence starting from the Middle Ages. In China, formal legislation on arbitration began in the modern era during the Republic of China period. However, the origins of arbitration as a method for resolving disputes can be traced back to ancient times, during the Qin and Han dynasties. The most significant modern arbitration legislation in China is the "Arbitration Law" enacted in 1995, which drew on the experiences of foreign arbitration laws. Despite this, there are still many areas in arbitration legislation that require improvement based on practical experiences. Currently, revisions to the Arbitration Law are underway, and historical experiences may offer valuable insights, assisting in better integrating the Arbitration Law with Chinese society. This article primarily focuses on the role and impact of the imported modern commercial arbitration system in China and how it can be harmonized with China's legal culture in the future.

In this research, a questionnaire was developed to investigate high school students' viewpoints, originating from science history, on 'motion of on object', the subjects were seventy- five 10th grade students and sixty-five 11th grade students. Results found that the highest percentage among the types of 10th grade students' thoughts was related to the Middle Ages 'Impetus' viewpoints. Percentages of 11th grade students' thoughts were highest for Middle Ages and Newton views. These results provided proof that the development of student thoughts' based on science history' are consistent with school year. Furthermore, student thought regarding 'object motion' under the conditions of no force, vacuum, or air under a weightless stage were related to progressive viewpoints on science history. However, the percentage of thoughts related to earlier viewpoints were considerable. Student thoughts on parabolic motion, circle motion, and conservation amount of motion were found to be highly significant in similarity to the viewpoints of Galilei, Descartes, and Huygens; view cultivated before Newton. Consequently, this study determined that educational efficiency could be raised by providing historically more progressive views to cope with conflictory student thoughts-thoughts related to past views in science history.

This study is to illuminate the problem of shadows and evil appearing in contemporary events in the midst of a period of upheaval through Inferno of Divine Comedy. First, the concept of shadow and evil were briefly summarized in analytical psychology and discussed the importance of considering the concepts with the empirical aspect of relativity and ethics in the field of psychotherapy. The 14th century, the age of Dante, was the embryonic period of the Renaissance beyond the end of the Middle Ages. It was when Dante, who was writing Divine Comedy, had to take off his persona forcibly and live in exile. In a nutshell, it was a transition period for both the individual and the collective. The dark forest is a nigredo, darkness and chaos we face in this transition, but it can be a place of transformation and rebirth. The three beasts (leopard, lion, and she-wolf) encountered in the forest can be considered as the instinctual images that Dante ignored and alienated, which the medieval Christian world had suppressed and eliminated. Especially at the collective level, as destructive instincts, ferocious beasts roam throughout society when a crisis breaks dominant laws of values. The three beasts of Inferno appear as phenomena of shadows and evil. The aspect of leopard was explored Cerberus and Chiaco(pig) as a symbol of greed, and the lion, Farinata as the form of violent passion. The aspect of the she-wolf was examined as Geryon, a deceitful monster with a beast nature hidden behind goodness, the giants in the frozen lake of Cocytus, and Branca D'Oria, who betrayed and murdered the country and family. Inferno reveals the "state" of being trapped when one yields to the evil hidden within oneself and falls into prey.

Modern footwear is accepted as a fashion accessory that plays the role of a point of style, which reflects trends and makes use of individuality and stylishness, not a practical means itself. This study considers diverse types of western shoes, which had been historically popular from, and about a role in accordance with it, and grasps the occurrence background and the aesthetic characteristics in shoes type, which had initiated fashion in the historically cultural aspect. Thus, the aim is to be conducive to developing design related to modern shoes. As a result of this study, shoe styles have changed in relation to the historical situation throughout every period from medieval times to mid-modern times. Two functions of shoes, practicality and aesthetics, could be observed tendency of leading fashion in the middle of mutual control and supplementation according to social conditions, economic strength in a person of wearing shoes, social standing, and gender. Accordingly, considering that designs related to shoes are influenced by the historical conditions, continuous research on unique designs according to each era is thought to be necessary to develop shoe designs of the future.
