The artist's interest has been captivated by ecological phenomena in Nature. Her keen captivation has then been focused into plastic art depicting the image of primitive life. The wide sweep of her work encompasses the totality of nature which consists of the human's subconscious power and imagination which she then portrays by organic images. These organic images are in contrast to scientific, mathematical and logical inference and consciousness. This research examines the character of the organic images in modern art by her analysis of some representative works by others. The image is an essential concept in the art which appeared in very different ways and in different perspectives. The image in the artwork appears to be the realistic expression until the early part of the 20th Century. Well into the 20th Century, it began being expressed in various ways such as combined images by imagination which is combined or rejected in the story of artwork. It also began being expressed by transferred images by changed original conditions. It is the main purpose of this research is to study of various expressions of organic images in the artwork of the Post-Modernism era. The character and meaning of organic image painting helps people to approach the human instinct more easily to find out the natural essence. It is also an objective of the organic image to tenderise our human sensibilities, thus helping us to regain vitality and recover our poor humanity in the barren wilderness of modern society. 'Life communion with nature' is a meeting point and common ground for Oriental Philosophy and organic image painting. Through this research, organic image painting is characterised in the four following ways : 1st) Organic image painting seeks regularity and perfection of outer shapes, in contrast to disordered and deformed nature, resulting in organic and biotic formalistic mode of plastic art. 2nd) Organic image painting seeks the formative. 3rd) Organic image painting pursues the priceless dignity of life by researching the formatted arrangement and figure, which contains primitive power of life. 4th) Organic image painting makes crystal clear the power of human and nature, which is a historic and biological phenomenon. This, in turn, exposes the humanistic view of the world from modern society best characterised in lost self-understanding, isolation and materialism. The representative organic image painting artists are Elizabeth Murray, Kusama Yayoi, and Niki do Saint Phalle. Elizabeth Murray used shaped canvas and a round construction of relief works. Kusama Yayoi used Automatistic expressionism originating from the realms of unconsciousness and which is represented by the mass and shape of a water drop. Niki do Saint Phalle shows the transcendence of universal life and anti-life to respect the dignity of life and the eco-friendliness relationship of human and nature in the post-modernism in art history. This is accomplished by surrealistic, symbolic, fantastic and humoristic expression. These three artists' works express the spirit of the organic image in contemporary art. It contains the stream of nature and life to seek not only the state of materialism in the reality, but also the harmonized world of nature and human which has almost lost the important meaning in modern times. Finally, this organic image is the plastic language of the majestic life. It is the romantic idea that the intimacy of nature and the universe and Surrealism, which emphasizes the unconsciousness , is the source of truth and spirit. Also it is influenced by primitive art and abstract art. According to this research, the subject 'Research About Organic Images' is not only an important element in the plastic arts from primitive society to the present, but is also fundamental to an true understanding of Post-Modernism.

After liberation from Japanese colonial rule in 1945, there was the three-year period of United States Army Military Government in Korea. In 1948, Democratic People's Republic of Korea, and Republic of Korea were established in the north and south of the Korean Peninsula. The Republic of Korea is now a modern state set in the southern part of the Korean. We usually refer to Koreans as people who belong to the Republic of Korea. Can we say that is true exactly? Why make of this an obsolete question? The period from 1945 when Korea was emancipated from Japanese colonial rule to 1948 when the Republic of Korea was established has not been a focus of modern Korean history. This three years remains empty in Korean history and makes the concept of 'Korean' we usually consider ambiguous, and prompts careful attention to the silence of 'some Koreans' forced to live against their will in the blurred boundaries between nation and people. This dissertation regards 'Koreans' who came to live in the border of nations, especially 'Korean-Japanese third generation women artists'who are marginalized both Japan and Korea. It questions the category of 'Korean women's art' that has so far been considered, based on the concept of territory, and presents a new perspective for viewing 'Korean women's art'. Almost no study on Korean-Japanese women's art has been conducted, based on research on Korean diaspora, and no systematic historical records exist. Even data-collection is limited due to the political situation of South and North in confrontation. Representation of the Mother Country on the Artworks by First and Second-Generation Korean-Japanese(Zainich) Women Artists after Liberation since 1945 was published in 2011 is the only dissertation in which Korean-Japanese women artists, and early artistic activities. That research is based on press releases and interviews obtained through Japan. This thesis concentrates on the world of Korean-Japanese third generation women artists such as Kim Jung-sook, Kim Ae-soon, and Han Sung-nam, permanent residents in Japan who still have Korean nationality. The three Korean-Japanese third generation women artists whose art world is reviewed in this thesis would like to reveal their voices as minorities in Japan and Korea, resisting power and the universal concepts of nation, people and identity. Questioning the general notions of 'Korean women' and 'Korean women's art'considered within the Korean Peninsula, they explore their identity as Korean women outside the Korean territory from a post-territorial perspective and have a new understanding of the minority's diversity and difference through their eyes as marginal women living outside the mainstream of Korean and Japanese society. This is associated with recent post-colonial critical viewpoints reconsidering myths of universalism and transcendental aesthetic measures. In the 1980s and 1990s art museums and galleries in New York tried a critical shift in aesthetic discourse on contemporary art history, analyzed how power relationships among such elements as gender, sexuality, race, nationalism. Ghost of Ethnicity: Rethinking Art Discourses of the 1940s and 1980s by Lisa Bloom is an obvious presentation about the post-colonial discourse. Lisa Bloom rethinks the diversity of race, ethnicity, sexuality, and gender each artist and critic has, she began a new discussion on artists who were anti-establishment artists alienated by mainstream society. As migration rapidly increased through globalism lead by the United States the aspects of diaspora experience emerges as critical issues in interpreting contemporary culture. As a new concept of art with hybrid cultural backgrounds exists, each artist's cultural identity and specificity should be viewed and interpreted in a sociopolitical context. A criticism started considering the distinct characteristics of each individual's historical experience and cultural identity, and paying attention to experience of the third world artist, especially women artists, confronting the power of modernist discourses from a perspective of the white male subject. Considering recent international contemporary art, the Korean-Japanese third generation women artists who clarify their cultural identity as minority living in the border between Korea and Japan may present a new direction for contemporary Korean art. Their art world derives from their diaspora experience on colonial trauma historically. Their works made us to see that it is also associated with postcolonial critical perspective in the recent contemporary art stream. And it reminds us of rethinking the diversity of the minority living outside mainstream society. Thus, this should be considered as one of the features in the context of Korean women's art.

Interrill erosion by the rainfall is divided into a detachment of soil particles by raindrop splash when raindrops having kinetic energy strike on the surface soil and a sediment transport by sheet flow of surface runoff. Rainfall kinetic energy is widely used as an indicator expressing the potential ability to separate the soil particles from soil mass. In this study, the soil erosion experiments of rainfall simulation were operated to evaluate the effects of rainfall kinetic energy on interrill erosion as using the strip cover to control raindrop impact. The kinetic energy from rainfall simulator was 0.58 times to that of natural rainfall. Surface runoff and subsurface runoff increased and decreased respectively with increase of rainfall intensity. Surface runoff discharge from plots of non-cover was 1.82 times more than that from plots with cover. The rainfall kinetic energy influenced on the starting time of surface and subsurface runoff. Soil erosion quantity greatly varied according to existence of the surface cover that can intercept rainfall energy. Sediment yields by the interaction between raindrop splash and sheet flow increased 3.6~5.9 times and the increase rates of those decreased with rainfall intensity. As a results from analysis of relationship between stream power and sediment yields, rainfall kinetic energy increased the transport capacity according to increase of surface runoff as well as the detachment of soil particles by raindrop splash.

This paper examined the conversion of methane to hydrogen and other higher hydrocarbons using dielectric barrier discharge with AC pulse power. Two metal electrodes of a coaxial-type plasma reactor were separated by gas gap and an alumina tube. The inner electrode was located inside the alumina tube. The alumina tube was located inside the stainless steel tube, which was used as the outer electrode. Effect of feed gas composition (methane, oxygen, argon, water and helium), flow rate, applied frequency, input volt-age on methane conversion and product distribution were studied. The major products of plasma chemical reactions were ethylene, ethane, propane, buthane, hydrogen, carbon monoxide and carbon dioxide. The increment of applied voltage and the usage of inert gas as the background (helium and argon) enhanced the selectivity of hydrocarbons and methane conversion. The addition of water in the feed stream enhanced the conversion of methane and yield of hydrogen. Higher voltage leads to higher yield of $C_2H_6,\;C_3H_8,\;C_4H_{10}$ and yield or $C_2H_2\;and\;C_2H_4$ appeared highly in lower voltage.

In hydrologic modeling, prediction uncertainty generally stems from various uncertainty sources associated with model structure, data, and parameters, etc. This study aims to assess the parameter uncertainty effect on hydrologic prediction results. For this objective, a distributed rainfall-sediment yield-runoff model, which consists of rainfall-runoff module for simulation of surface and subsurface flows and sediment yield module based on unit stream power theory, was applied to the mesoscale mountainous area (Cheoncheon catchment; 289.9 $km^2$). For parameter uncertainty evaluation, the model was calibrated by a multi-objective optimization algorithm (MOSCEM) with two different objective functions (RMSE and HMLE) and Pareto optimal solutions of each case were then estimated. In Case I, the rainfall-runoff module was calibrated to investigate the effect of parameter uncertainty on hydrograph reproduction whereas in Case II, sediment yield module was calibrated to show the propagation of parameter uncertainty into sedigraph estimation. Additionally, in Case III, all parameters of both modules were simultaneously calibrated in order to take account of prediction uncertainty in rainfall-sediment yield-runoff modeling. The results showed that hydrograph prediction uncertainty of Case I was observed over the low-flow periods while the sedigraph of high-flow periods was sensitive to uncertainty of the sediment yield module parameters in Case II. In Case III, prediction uncertainty ranges of both hydrograph and sedigraph were larger than the other cases. Furthermore, prediction uncertainty in terms of spatial distribution of erosion and deposition drastically varied with the applied model parameters for all cases.

The shallow sediments in the southwestern Ulleung Basin consist of mass flow deposits such as slide/slump and debris flow deposits (DFD), caused by slope failure. These sediments are proven to be important in studying geological disaster and stability of the seafloor. In this paper, we analysised the flow accumulation and slope failure susceptibility of the Ulleung Basin on the basis of multi-beam data, collected in this area. We also studied the distribution pattern and the seismic characteristics of the DFD in the uppermost layer of the Ulleung Basin on the basis of seismic data. The slope susceptibility was calculated as the frequency ratio of each factors including slope, aspect, curvature and stream power index (SPI), which causes the slope failure. These results indicate that the slope failure is frequently to occur in the southern and western continental slope of the Ulleung Basin. The sediment flow (mass flow) caused by the slope failure converges to the north and northwest of the Ulleung Basin. According to the seismic characteristics, the uppermost layer in study area can be divided into four sedimentary unit. These sedimentary units develop from the south and southwest to the north and northwest in association with slope susceptibility and flow accumulation.

Fashion is one of the characteristics which represents the comtemporary sociocultural signifiant. A style that a certain stream of fashion brings is not just limited in fragmentary tendencies and fads. That can be a code to communicate and function as a medium in itself. Music has been displaying it's power to fashion while fashion has been exercising it's influence over the music. There is an inseparable relationship between music and fashion in terms of expressing our images of the world: fashion delivers them through visuality and music does it by sound. Both fashion and music are reflecting our society as well as they are influencing on sociocultural aspects generally. Whenever music has been changed new youth culture has been made and this culture has been expanded with forming some distinct fashion trends. The study focuses on identifying the relations between pop music and fashion styles which are occupying positions firmly on the bases of youth culture through analysing the relations between the fashion styles and music genres which are used in sub-culture groups to express their own identities and consciousness from a point of semiotics. In conclusion, subculture is the exit of their escaping from the compelling inconsistency cause by the condition of people's life and the way for them to solve through cultural sublimating for themselves. People come up with distinctive style of music and fashion to express their resistant signifie in their symbolic way. In addition, a particular music trend has much to do with a contemporary fashion style. In the relationship between music and fashion, there have been the subtle mechanism to boost and influence and some crucial similarity each other to signify inner values of the times. This study lets us realize that fashion is not only a popular style of clothes, hair, etc. at a particular time or place but also a medium to communicate and to guarantee polysemous identity by functioning as a flexible tool to exchange contemporary sociocultural meanings.

The power water flowed out from the multipurpose darn influences the ecosystem approximately because of the low water temperature. An appropriate counter measure to the rising water temperature is needed for growing crops especially when the temperature is below 18˚C in the source of the irrigation water This observational study is practiced in Yong-Doo water warming canal and pond in the down stream of Choong-Ju multipurpose dam and is practiced for analyse and compare the rising effects in actural water temperature by actual measurement with the rising effects of planned water temperatuer by the basic theoritical method and for the help to present the direction in plan establishment through investigate the results afterwards. The results are as follows. 1.The degree of the rise of the water temperature can be decided by $\theta$x=$\theta$o +K L--v.h (T-$\theta$˚)Then, K values of a factor representing the characteristics of the water warming canal were 0.00002043 for the type I. and 0.0000173 for the type II. respectively. 2.A variation of water temperature which produced by the difference effective temperature and water temperature in the water warming canal was $\theta$x1 = 16.5 + 15.9(1-e -0.00018x), $\theta$x2 =18.8 + 8.4( 1-e -0.000298x)for the type I. and $\theta$x, = 19.6 + 12.8 ( 1-e -0.00041x) for the type II. 3.It was shown that the effects of the rise of water temperature for the type I. water warming canal were greater than that of type II. as a resultes of broadening the surface of the canal compared with the depth of water, coloring the surface of water canal and installing the resistance block. 4.In case of the type I. water warming canal, the equation between the air temperature and the degree of the rise of water temprature could be made ;Y= 0.4134X + 7.728 In addition, in case of the type II. water warming canal, the correlation was very low. 5.A monthly variation of the water temperature in the water warming canal was the highest in August during the irrigation period and the water temperature rose with the air temperature until August. However, it was blunted after then. 6.A rising degree of water temperature of the practical value in the water warming pond was higher than that of the theoritical equation by 69% for the type I. and 57% for the type II. Accordingly, it was possible to acquire the result near the practical value.$\theta$w-$\theta$o=[1-exp{ -h(1+2$\psi$) . X($\theta$w-$\theta$0)XC Here, C values are 1.69 for the type I. and 1.57 for the type II. 7.It was shown that the effect of the rise of water temperature was favorable when the thermal absorption was to be good by coloring the surface of the water warming pond and removing the bottom osmosis. 8.By enlarging the surface of water in comparison with the depth, and by having dead area of water in the water warming pond, this structure in the water warming pond is helpful for the rise of water temperature.

As for the taboo of dress and its ornaments which was applied to only populace one-sidedly mainly under the power structure of feudalistic centralization of government like Chosun dynasty, the aspect of taboo was diversified all the more by having relation with various phenomenon of social structure characteristics, and the taboo items to be given in accordance with the flow of time shows the diversity. Especially, the structure of dress and its ornaments in Chosun period showed the side of social position relation and luxury control, and the taboo of dress and its ornaments which was derived from the current thought about China was given frequently. To respect the frugal virtue and moderate the life has relation with the stream of the times in individuals or nations. And, that it is externalized is dress and its ornaments. As the luxury about dress and its ornaments was serious in accordance with times, it appeared by having relation with whole economic question of nations. Then, this researcher thought this by relating this to the culture of customs. This researcher thought that the luxury about clothing gets to go to extremes and the law and order collapses, according as public morals get to be very lax. And, it can be said that the way to be able to control this is that the customs should be thoroughly obeyed and that the system to be able to play the role of braking is taboo. So, this researcher thinks that it is significant to examine the achievement which has contributed toward the life of dress and its ornaments by successive kinds on the basis of a true record of the Vidynasty and other all sorts of literatures about the real situation of prohibition order which has been from the first king to Kojong at the last period of nation. The criticism and taboo about luxury which have been discussed at Chosun period may be subdivided into some kinds in accordance with the subjects. But, in this tests, as it sis the real situation that the case to be due to the lavish necessary articles for marriage which is coming to fore as our social problem nowadays is increasing remarkably, this researcher tries to examine the taboo about the marriage luxury at Chosun period in the order of successive generations. Thus, before examining the taboo of marriage luxury, this researcher tries to examine about the taboo of textile luxury and study the taboo of marriage luxury, as the marriage luxury governs almost everything of textile luxury and it is regarded as the origin of marriage luxury, especially. And, this researcher tries to study as to how was the penal regulations based on it at the same time.

Cooling of hot sections, especially the turbine nozzle and rotor blades, has a significant impact on gas turbine performance. In this study, the influence of precooling of the cooling air on the performance of gas turbines and their combined cycle plants was investigated. A state-of-the-art F-class gas turbine was selected, and its design performance was deliberately simulated using detailed component models including turbine blade cooling. Off-design analysis was used to simulate changes in the operating conditions and performance of the gas turbines due to precooling of the cooling air. Thermodynamic and aerodynamic models were used to simulate the performance of the cooled nozzle and rotor blade. In the combined cycle plant, the heat rejected from the cooling air was recovered at the bottoming steam cycle to optimize the overall plant performance. With a 200K decrease of all cooling air stream, an almost 1.78% power upgrade due to increase in main gas flow and a 0.70 percent point efficiency decrease due to the fuel flow increase to maintain design turbine inlet temperature were predicted.
