This study explores the creation and enjoyment of Kuwoonmong (九雲夢) using a reference system called the cultural imagination, which is related to the Yin-Yang (陰陽) and Wu Xing (五行). When Kim Manjung wrote Guwoonmong, he may have composed figures and events based on this imagination. In particular, when he designed the eight seonnyeo (팔선녀), he set the order such as Gap (甲), Eul (乙), Byeong (병), Jeong (丁), etc. and characterized them according to the celestial stem (天干). Thus it was easy to avoid overlapping of characters and to construct various stories and relationships between them. The table below shows the characters of Kuwoonmong corresponding to the celestial stem. In not only the individual person but also the narrative world, Kuwoonmon demonstrates Yin-Yang and Wu Xing's imagination. In this respect, Kuwoonmon can be considered a large symbol encompassing the abstract theory of Yin-Yang and Wu Xing. Of course, the writer, Kim, Manjung would not have tried to symbolize the principle intentionally. However, he was also present in the environment of the cultural imagination that has been formed over the years. The same is true for the contemporary recipients of Guwunmong. They would have had a pleasant experience applying the cultural imagination and strengthening their familiar world view and human view.

This study examines Korean language translations of traditional Chinese hansi in the 1910s and 1920s. In the $20^{th}$ century, many poets translated Chinese and Korean traditional hansi into Korean. In the early $20^{th}$ century, Korean language began to be used as a national public language. At that time, not only hansi but also poetry from several other languages had been translated into Korean. Choi Nam-sun in the 1910s and Kim So-woel, Kim Eok, and Lee Kwang-su in the 1920s translated Chinese traditional hansi, focusing on famous Dang dynasty poetry from Tu Fu and Li Bai, etc. Choi Nam-sun's translation in the 1910s aimed to consider poetry as a written literature. On the contrary, Kim So-woel, Kim Eok, and Lee Kwang-su believed that Korean modern verse literature should be songs as well as poetry, and their translations in the 1920s aimed to create songs as spoken literature by focusing on orality and universality. Though Korean is now the language, the literary history of hansi continues in modern poetry.

In order to develop constructed wetlands for treating hydroponic wastewater in greenhouses, removal efficiencies and decomposition velocities of pollutants in constructed wetland were investigated for treating hydroponic wastewater. Removal rates of BOD, COD, SS, T-N and T-P in effluent in constructed wetlands were 88%, 79%, 92%, 64% and 92%, respectively. The decomposition velocities (K; $day^{-1}$) of pollutants in $1^{st}$ HF bed of constructed wetlands were higher in the order of SS ($0.54day^{-1}$) > BOD ($0.39day^{-1}$) > COD ($0.27day^{-1}$) > T-P ($0.26day^{-1}$) > T-N ($0.06day^{-1}$). In $1^{st}$ HF bed of constructed wetlands, the decomposition velocity of SS was rapid than that for BOD, COD, T-N and T-P in constructed wetland for treating hydroponic wastewater. The decomposition velocity (K; $day^{-1}$) of pollutants in $2^{nd}$ HF bed of constructed wetland were higher in the order of T-P ($0.52day^{-1}$) > BOD ($0.28day^{-1}$) > COD ($0.15day^{-1}$) > T-N ($0.06day^{-1}$) > SS ($0.10day^{-1}$). In $2^{nd}$ HF bed of constructed wetlands, the decomposition velocity of T-P was rapid than that for BOD, COD, SS and T-N in constructed wetland for treating hydroponic wastewater.

A wide diversity of liquid fertilizers and composts produced from the livestock manure in Korea is commonly applied to agricultural lands as an alternative of chemical fertilizers. However, their effects on the crop production and environmental impacts are still vague. The current study was investigated the property changes of paddy soils in sandy loam and silty loam treated with 1) control (no treatment), 2) chemicals, 3) storage liquid fertilizer and 4) SCB liquid fertilizer located in Gyeong-gi province, Korea. The chemical properties of soils in sandy loam and silty loam before the treatment were similar with the ones in the average paddy fields in Korea. Contrary to this, the amount of available phosphorus in sandy loam was higher than the one in the average paddy fields. The number of living organisms in sandy loam and silty loam treated with storage liquid fertilizer and SCB liquid fertilizer were higher than the ones in sandy loam and silty loam with no-treatment and chemicals. Significant difference (P<0.05) among the treatments and no-treatment was observed in sandy loam rather than in silty loam. The amounts of heavy metals were the highest in both sandy loam and silty loam treated with storage liquid fertilizer and SCB liquid fertilizer. The comparison of heavy metals showed that the ones in silty loam were little bit higher than sandy loam. The leaf lengths and dry weights of rices were increased over time, however, no significant difference was observed among each treament. In addition, the rice yield in sandy loam treated with SCB liquid fertilizer was higher than the ones in sandy loam. The highest rice yield was obtained from sandy loam treated with chemicals, but there was no significant difference between storage liquid fertilizer and SCB liquid fertilizer. While the rate of nutrient absorption by rices was the highest in sandy loam and silty loam treated with chemicals, there was no significant difference in sandy loam and silty loam treated with livestock liquid manure.

This study applied the theory of Landscape Ecology to representative resources of Jeju Olle-gil, which is a representative subject of walking tourism, to identify ecological characteristics and to establish a technique for landscape ecological analysis of Olle-gil resources. Jeju Olle Trail type based on the biotope type, major land use, vegetation status around Olle Trail and roads were divided into 12 types. Based on the type of ecological tourism resource classification, the Jeju Olle-gil walking tourism resource classification was divided into seven types of natural resources and seven types of humanities resources, and each resource was characterized by Geotope, Biotope, and Anthropopope, just like the landscape ecology system. Geotope resources are strong in landscape characteristics such as coast and beach, rocks, bedrocks, waterfalls, geology and Jusangjeolli Cliff, Oreum and craters, water resources, and landscape viewpoints. The Biotope resources showed strong ecological characteristics due to large tree and protected tree, Gotjawal, forest road and vegetation communities, biological habitat, vegetation landscape view point. Antropotope include Culture of Jeju Haenyeo and traditional culture, potting and lighthouses, experience facilities, temples and churches, military and beacon facilities, other historical and cultural facilities, and cultural landscape views. Jeju Olle Trail The representative resources for each type of Jeju Olle Trail are coastal, Oreum, Gotjawal, field and Stonewall Fencing farming land, Jeju Village and Stone wall of Jeju. In order to learn about the components and various functions of the resources representing the Olle Trail's ecological culture, the landscape ecological technique was interpreted. Looking at the ecological and cultural characteristics of coastal, the coast includes black basalt rocks, coastal vegetation, coastal grasslands, coastal rock vegetation, winter migratory birds and Jeju haenyeo. Oreum is a unique volcanic topography, which includes circular and oval mountain bodies, oreum vegetation, crater wetlands, the origin and legend of the name of Oreum, the legend of the name of Oreum, the culture of grazing horses, the use of military purposes, the object of folk belief, and the view from the summit. Gotjawal features rocky bumps, unique microclimate formation, Gotjawal vegetation, geographical names, the culture of charcoal being baked in the past, and bizarre shapes of trees and vines. Field walls include the structure and shape of field walls, field cultivation crops, field wall habitats, Jeju agricultural culture, and field walls. The village includes a stone wall and roof structure built from basalt, a pavilion at the entrance of the village, a yard and garden inside the house, a view of the lives of local people, and an alleyway view. These resources have slowly changed with the long lives of humans, and are now unique to Jeju Island. By providing contents specialized for each type of Olle Trail, tourists who walk on Olle will be able to experience the Olle Trail in depth as they learn the story of the resources, and will be able to increase the sustainable use and satisfaction of Jeju Olle Trail users.

The 10th constitution established in 1987 serves as the theoretical foundation of democracy in South Korea in the 21st century. Respect for human rights, resistance to injustice, and equality consciousness inherent in this constitution do not conflict with the content of Confucian philosophy. This means that the spirit of the constitution of South Korea in the 21st century was formed under the influence of the idea of democracy and Confucian philosophy. However, the 10th constitution attaches importance to the idea of the 'Basic free and democratic order', which was accepted in the Yushin constitution and inherited by the military forces. The Yushin constitution was affected by liberalism that prioritizes freedom over equality rather than supporting the compatibility between freedom and equality. Therefore, policies to expand the interests of the bourgeoisie rather than public welfare or the interests of the public have been implemented frequently. In particular, during the Lee Myeong-bak and Park Geun-hye regimes, many unequal phenomena were mass-produced. Confucian philosophy in the 21st century critically sees this unequal society. Confucian philosophy thinks that a sense of relative deprivation plays a role of alienating humans and emphasizes the importance of equal relationships. In addition, this constitution emphasizes the rule of law. However, the rule of law attaches importance to positive laws when the spirit of the constitution that contains natural law is applied to reality through systems. This rejects autonomous judgments and choices while inducing reliance on heteronomy. These heteronomous laws as such are accompanied by forcibleness. The positive laws as such can degrade humans into passive beings that indiscriminately adapt themselves to frames already set instead of active beings that think freely and creatively. Confucian philosophy regards and criticizes the rule of law as a system that makes humans into a means. Confucian philosophy regards humans as moral beings instead of tools. Confucian philosophy seeks to build a healthy society through morality accomplished through conscious realization of the principles of life. Confucian philosophy regards humans as originally free beings. Therefore, human beings are autonomous beings, not heteronomous beings. According to Confucian philosophy, humans beings that can realize the morality contained in their inner side by themselves to responsibly carry out their own judgments and choices. Therefore, Confucian philosophy, which considers human beings as beings to be trusted instead of beings to be distrusted, attaches importance to the realization of human decency through edification rather than by punishment through the law. This means that human values cannot be kept by the heteronomy termed positive laws but the identity of humans can be maintained by voluntary choices and judgments. As such, the comment of Confucian philosophy on the problems of liberal democracy and positive laws contained in the 10th constitution can be helpful in essentially solving the contradictions of modern South Korean society.

One of central issues in the Literature and Science discourses during the Victorian era is the relation of physiology to psychology. Many thinkers tackle the question of whether or not psychic phenomena can be reducible to their physiological bases. For instance, Victorian physiologist William Benjamin Carpenter claims that there should be a boundary between physiological and psychological qualities. Yet, his contemporary writer Grant Allen contends for the reduction of psychology into physiology. In the essay, I discuss Grant Allen's work Physiological Aesthetics (1877) so as to eventually problematize his physiological reductionism. I especially highlight the paradox of his physiological aesthetics. In order to clarify my argument, I introduce two concepts: evolutionary aesthetics and physiological reductionism. On the one hand, Allen argues for the development of aesthetic appreciation. The gradual evolution from gaudy to serene colors, for instance, reflects the fine differentiation of sensory organs. He believes that the existence of varied aesthetic pleasures corresponds to the evolution of sensory nerve structures. Nonetheless, Allen ironically gives more weight to the commonality of aesthetic experiences than to this teleological ordering of aesthetic experiences. He argues that there is no fundamental difference among humans in terms of their aesthetic assessments. Furthermore, there is even no essential distinction among plants, animals, and humans in light of their aesthetic appraisals, he states firmly. Although he asserts the gradual advance of aesthetic feelings caused by the intricacy of nervous systems, he simultaneously trivializes the evolution of aesthetic appraisal. In the essay, I highlight this paradox in Allen's physiological aesthetics. It should be underscored, lamentably enough, that Allen seeks biological purity by erasing fine lines among physiology, psychology, and sociality. He estranges aesthetic experiences from subjective variations and their socio-cultural contexts. He makes great efforts to eliminate individual differences and socio-cultural specificities in order to extremely biologize aesthetic experiences. Hence, Allen's physiological aesthetics is marked as the politics of physiological purification.

Citrus unshiu peel extracts possess a variety of beneficial effects, and studies on their anticancer activity have been reported. However, the exact mechanisms underlying this activity remain unclear. In the current study, the apoptotic effect of ethanol extract of C. unshiu peel (EECU) on human breast adenocarcinoma MDA-MB-231 cells and related mechanisms were investigated. The results showed that the survival rate of MDA-MB-231 cells treated with EECU was significantly inhibited in a concentration-dependent manner, which was associated with the induction of apoptosis. EECU-induced apoptosis was associated with the activation of caspase-8 and caspase-9, which initiate extrinsic and intrinsic apoptosis pathways, respectively, and caspase-3, a representative effect caspase. EECU suppressed the expression of the inhibitor of apoptosis family of proteins, leading to an increased Bax/Bcl-2 ratio and proteolytic degradation of poly (ADP-ribose) polymerase. EECU also enhanced the loss of the mitochondrial membrane potential and cytochrome c release from the mitochondria to the cytosol, along with truncation of Bid. In addition, EECU activated AMP-activated protein kinase (AMPK), and compound C, an AMPK inhibitor, significantly weakened EECU-induced apoptosis and cell viability reduction. Furthermore, EECU promoted the generation of reactive oxygen species (ROS), which acted as upstream signals for AMPK activation as pretreatment of cells, with the antioxidant N-acetyl cysteine reversing both EECU-induced AMPK activation and apoptosis. Collectively, these findings suggest that EECU inhibits MDA-MB-231 adenocarcinoma cell proliferation by activating intrinsic and extrinsic apoptotic pathways, which was mediated through ROS/AMPK-dependent pathways.

In this article, I outlined the archival management system in Early Joseon Dynasty and examined the characteristics of the system. At first, I explained the three aspects of the archival management; the memory of the past, the documentation of the contemporary, and the vision of the future through the documentation. Secondly, I tried to understand the character of the Veritable Record and its compilation by the concepts of archival science such as 'authenticity', 'reliability'. In the memory of the past, the History of a Dynasty(Koryo-Sa) and the Comprehensive History of Eastern Kingdom were included. The arrangement of the past was accompanied with the systematic study of the domestic and foreign histories. At the beginning of the state building, there was many practical need to the experiences of government and social re-construction. It was also the process of the legitimacy establishment of the new dynasty. And the Bureaucracy promoted the development of the records and archival management system because it needed the continuity and evidence of business. The dualistic structure of the records and archival management system was the most unique character of this age. The management of general administrative records was not different from the modern one. But the historical drafts and the compilation of Veritable record were different. Here, I had to examine the characteristics of these procedures by the concept authenticity, reliability, and custodianship. In doing so, I suggested the need of conceptualization of the historical terms such as 'the primary sources' and 'the secondary sources' in historical study. The archival concepts will be the most useful means to that issue. Through the memory of the past and the documentation of the contemporary, they made visions of the future, new vision of the Literati Governance. In this tradition, in spite of the revision of the Veritable records by the new changed political party, both the orignal and the revised remained as the comparative evidence for the future generation in the name of the Black-Red Revised History.

Archaeological heritages are precious cultural relics and public assets that must be preserved, conserved, and shared with people all over the world. Investigating archaeological heritage is valuable and plays an important role for the public good; our ancestors' cultures can be restored, and it helps with developing a clear understanding of the cultural and social aspects of a historical period as well as teaches about historical factors unreported in the literature. One of the most basic and important conditions necessary for recognizing the value and importance of archaeological heritage investigation, expertise, and quality improvement is to establish detailed criteria for investigation services and the qualification examination of archaeological heritage. Observation of detailed criteria and the qualification examination of archaeological heritage can partially demonstrate society's recognition of strengthening transparency, public property, and the objectivity of the investigation of archaeological heritage. However, the detailed criteria for investigation services and the qualification examination of archaeological heritage currently implemented as administrative rules are neither followed by all institutes in the public and private sectors nor the government. Thus, there are serious problems in terms of the effectiveness and stability of institutions. The detailed criteria for the qualification examination breach the principle of statutory reservation, the principle of statutory regulation, and regulations on the announcement and management of orders and rules. Non-compliance with compensation criteria for investigation services or with detailed criteria for the qualification examination of archaeological heritage will be one of the reasons for the failure of the investigation foundation for archaeological heritage in the future. That is, it will result in the expansion, reproduction, and repetition of a vicious cycle of conflict between developers, who are the decision-makers responsible for selecting an investigating organization for archaeological heritage and determining the cost, and investigating organizations. This includes the impractical shortening of investigation periods and reducing costs by developers, distrust of the values and the importance of investigations of archaeological heritage, a decrease in quality, accidents caused by a lack of safety, a lack of occupational ethics, and non-recruitment of new experts, etc. Therefore, it is necessary to change the structure from a vicious cycle to a virtuous cycle, and promote the enactment of regulations that will ensure effectiveness and stability in the process of attaining the goals of the institution and application of the institution, as well as the continuous advancement of work to fill the gaps with reality.
