This study conducted a comparative analysis between Koreans and foreigners on how they feel of the 'Oreum' so that the data could be used to conserve and utilize 'Oreum' as a brand of Jeju, which is one of the natural and original sceneries of the island along with Halla Mountain. Four aerial photo slides were selected to be assessed among 18 overlooked views of 'Oreums' through quasi-preliminary and preliminary surveys. The assessment group was divided into native and foreigner groups. Image and preference were measured based on 7 step categorization on 26 adjectives, and factor analysis was implemented. The selected factors from factor analysis reflected that calmness was recognized as common image identification variable to natives and foreigners. However, foreigners choose 'dynamics', 'peculiarity' and 'grandeur' in order to explain the image while Koreans selected words in the order of 'attractiveness', 'grandeur', 'dynamics' and 'peculiarity'. This means Koreans identify the image of 'Oreum' as absolute beauty while foreigners see the dynamics and relative peculiarity as its attractive point. As a result of factor score, preference and multiple regression analysis, Koreans selected 'calmness', 'attractiveness' and 'dynamics' as important variables to explain preference. On the other hand, foreigners choose 'dynamics' and 'calmness' as well as 'evenness', 'peculiarity' and 'simplicity'. This represents that foreigners are highly influenced by the structural peculiarity and simplicity on the image preference.

Image which appears in fashion illustration on the late twentieth century is not the representative image as an equivalence to the real fashion styles but the virtual image which bears no relation to any reality. The purpose of this study is review the concept of virtuality and analyze in which way virtual image is expressed in fashion illustrations on the background of Jean Baudrillard's simulacre theory. In post-modem paintings the expression methods of image-virtualization were image mixing through photo-image appropriation, image overlapping, and the icons inserted unreasonably, the focus-out effect through scrubbing and the over-painting on the photograph. Image-virtualization in fashion illustration was expressed through image mixing and expression of image uncertainty. Image mixing was made by photo-image appropriation, image overlapping, connection of heterogeneous images and using interface image, and uncertain image was expressed through the expression of visual ambiguity and virtual movement.

Animations consist of the created artificial images. To interpret of the meaning from analyzing the style of main images is an important element in understanding of animations. Therefore, to analyze images expressed in works of Miyazaki-hayao, this study substitutes the concept of 'hybridity' for images of characters, backgrounds, and mechanics created by him and explores how they are expressed, how they produce symbolic meanings and functions. It is confirmed that main images in selected works as a scope of research have hybridity of images between 'past, present, and future', 'eastern elements and western elements', 'real and virtual', 'human beings and animal' in narrative. From these results, it is concluded that because of hybridity between images, he can present fresh pleasures to spectators, simultaneously communicate thoughtful messages above mere enjoyment, which is a differentiable point with works of other directors.

The viscous force of fluids and the capillary force acting on the pore network of the porous media are important factors determining the immiscible displacement during geological $CO_2$ sequestration, these were directly affected by geological formation conditions and injection conditions. This study aimed to observe the migration and distribution of injected fluid and pore water, and quantitatively investigate displacement efficiency on various injection temperatures. This study aimed to perform micromodel experiments by applying n-hexane used as a proxy fluid for supercritical $CO_2$. In this study, immiscible displacement process from beginning of n-hexane injection to equilibrium of the distribution of the n-hexane and pore water was observed. The images from experiment were used to observe the displacement pattern and estimate the areal displacment efficiency of the n-hexane. For investigate the affects of the injection temperatures on the migration in macroscopic, migration of n-hexane in single pore was analyzed. The measurement revealed that the displacement efficiency at equilibrium state decreases as the temperature increases. The result from experiments indicate that the temperatures can affect the displacement pattern by changing the viscous forces and the capillary forces. The experimental results could provide important fundamental information on reservoir conditions and fluid injection conditions during geological $CO_2$ sequestration.

The geological CO2 sequestration in underground geological formation such as deep saline aquifers and depleted hydrocarbon reservoirs is one of the most promising options for reducing the atmospheric CO2 emissions. The process in geological CO2 sequestration involves injection of supercritical CO2 (scCO2) into porous media saturated with pore water and initiates CO2 flooding with immiscible displacement. The CO2 migration and distribution, and, consequently, the displacement efficiency is governed by the interaction of fluids. Especially, the viscous force and capillary force are controlled by geological formation conditions and injection conditions. This study aimed to estimate the effects of surfactant on interfacial tension between the immiscible fluids, scCO2 and porewater, under high pressure and high temperature conditions by using a pair of proxy fluids under standard conditions through pendant drop method. It also aimed to observe migration and distribution patterns of the immiscible fluids and estimate the effects of surfactant concentrations on the displacement efficiency of scCO2. Micromodel experiments were conducted by applying n-hexane and deionized water as proxy fluids for scCO2 and porewater. In order to quantitatively analyze the immiscible displacement phenomena by n-hexane injection in pore network, the images of migration and distribution pattern of the two fluids are acquired through a imaging system. The experimental results revealed that the addition of surfactants sharply reduces the interfacial tension between hexane and deionized water at low concentrations and approaches a constant value as the concentration increases. Also it was found that, by directly affecting the flow path of the flooding fluid at the pore scale in the porous medium, the surfactant showed the identical effect on the displacement efficiency of n-hexane at equilibrium state. The experimental observation results could provide important fundamental information on immiscible displacement of fluids in porous media and suggest the potential to improve the displacement efficiency of scCO2 by using surfactants.

Digital media technology has power of influence as extended in not only science and technology but also our society and culture. These phenomenon is explained as 'digital convergence'. Edmond Couchot argue the term 'hybridization'. Yvonne Spielmann and Jay David Bolter also argue that digital hybrid artworks across and integrates a diverse range of modes of representation, such as image, text, sound, space and bodily modes of expression. They must also address communicative interaction in the convergence of real and virtual spaces. In this paper, I noticed mixed reality environment which is seen as the form of hybrid between real and virtual object. And I discuss about this phenomenon as the study of interdisciplinary between art and science.

여러 가지 장점으로 인해 Ni-Ti 전동 파일을 근관성형에 사용하는 빈도가 점차 증가되는 추세이지만, 초심자를 대상으로 한 연구는 부족한 실정이다. 이에 본 연구에서는 초심자에서 Ni-Ti 전동 파일을 사용할 때 근관 형성의 효용성을 평가하고, 어떤 방법이 초심자에게 적절한지를 알아보고자 하였다. 근관형태가 재현된 레진 블록을 이용하여 12명의 초심자와 4명의 숙련자가 근관 형성을 시행하였다. 각 술자는 ProFile, ProTaper, Hybrid (ProFile＋ProTaper)를 이용하여 각각의 레진 블록을 세 개씩 근관형성하고, 각 파일 별의 근관 형성 시간을 기록하였다. 근관 형성 전과 후의 digital 이미지를 중첩하여 치근단으로부터 1, 2, 3, 4, 5, 6, 7mm level에서 근관단면의 총길이 변화량, 만곡 외측의 길이 변화량, 만곡 내측의 길이 변화량, 중심이동량, 중심이동율과 치근단에서의 apical transportation을 구하고, 초심자와 숙련자 사이의 차이를 비교 평가하였다. 실험결과 ProFile군의 1, 3, 5, 6, 7mm level과 ProTaper군의 6mm level, Hybrid군의 3mm level에서 초심자의 근관단면의 총길이 변화량이 숙련자보다 많았다. 모든 군에서 치근단으로부터 4, 5, 6, 7mm level에서는 근관 중심이 만곡내측으로 이동하였고, 1 2, 3mm level 에서는 만곡외측으로 이동하였으나, 숙련자가 시행한 Hybrid군의 3mm level과 비숙련자가 시행한 ProTaper 군의 3mm level에서는 만곡내측으로 이동하였다. 모든 군의 3mm level과 ProFile 군의 5mm level에서 초심자의 중심이동율이 숙련자에 비해 컸으며, 초심자가 ProTaper를 사용시 더 큰 apical trans portation을 보였고, 모든 군에서 초심자가 근관형성시 더 많은 시간이 걸렸다. ProFile과 ProTaper를 이용한 Hybrid technique이 초심자에게 추천되며, 초심자들도 충분히 교육받는다면 만곡된 근관의 근관형성에 있어서 Ni-Ti rotary file의 이용이 가능하리라고 사료된다.

Reinterpretation of the visual characteristics of Korean folk painting in contemporary Korean painting is to seek directions of today's Korean painting. When examining expressions of contemporary painting we see that there is a reappearance of iconic images, a reinterpretation of both flatness and multi-perspectives, and an objectifying of pastiche folk icons with an experimental spirit. All of these techniques suggest methods of contemporary Korean painting through 'folk painting'. Although folk painting has been adopted in contemporary Korean painting for a long time, interest increased in the 1980s. With the prevailance of both national characteristic expressive techniques of realism and color painting, artists reinterpreted folk painting in their work, borrowing the traditional five colors, common contents, and iconic images. Particularly, an interest in 'Korean Beauty' drew people's interest back to folk painting which provided the significant 'Korean Beauty' of traditional expressive techniques. This study is to examine the characteristics of selected group of works that created a new expressive technique in today's Korean painting by either the reappearance or the reinterpreting of iconic images of the Chosun Dynasty's folk painting. To achieve these goals, the artists, who modify or reinterpret folk painting's visual characteristics with a contemporary sense, are divided into three categories in this study; 'The Readoption of the Folk Image', 'The Reinterpretation of Folk Characteristics', and 'Experimental Expressions'. As a result, it proves that folk painting is both a classical expression and national expression which was not only favored in the Chosun period, but also can be reinterpreted through today's visual methodology.

This study explores the political parody, which has become an active art form in order to express Korean Internet users' political practices, especially, during the politically turbulent periods from the presidential election of 2003 to the recent candlelight vigil protest of 2008. This study investigates the rise and fall of a parody culture by online users from the mid-2000s, and also examines aesthetical aspects of parodic artworks relying on amateurism culminated in 2004. Specifically, the current study questions an aesthetical lack shown in 'appropriation', by which most of the online users simply produce imitations of original image. This study rather notes 'photomontage' as an aesthetic prototype, the political aesthetics made by John Heartfield, through which this study intends to observe how his aesthetical legacy of political art could be realized in the contemporary form of political parodies produced by online users. The present paper concludes that online users' political participations in producing critical works of art could allow us to negate the dichotomy between the elite and the mass, professional artists and amateur parodists, and a radical politics and the politics of style.
