  • 컴퓨터에 의해 촉발된 디지털 미디어 기술은 그 발전 속도가 나날이 가속화되어, 현재는 과학기술 분야뿐만 아니라 사회 문화적으로 확장되어 커다란 영향력을 갖게 되었다. 이러한 확장과 영향력에 대해 국내에서는 '디지털 컨버전스'라는 용어로 축약되어 설명될 수 있는데, 에드몽 꾸쇼(Edmond Couchot)는 'hybridization' 이라는 용어로 설명한 바 있다. 슈필만과 볼터(Yvonne Spielmann and Jay David Bolter)는 이러한 혼성적인 디지털 미디어 작품들은 이미지, 텍스트, 사운드, 공간 그리고 구체적 표현 방법 등의 다양한 범위의 재현 형식을 넘나들며 통합되고 있다고 하였으며, 이러한 혼성적인 특성 중 실재(real)적인 것과 가상(virtual)적인 것의 융합으로 인해 이루어지는 상호소통에 대해 다루어야 함을 역설한 바 있다. 본 논문에서는 실재와 가상이 융합된 결과물의 형태로 보여지는 혼합 현실 환경에 주목하여 이러한 적극적인 상호소통을 필요로 하는 양극의 주체인 과학기술과 문화예술간의 적절한 접점으로 수렴되고 있는 분야 중의 하나인 혼합현실형 공공 문화콘텐츠를 예를 들어 미디어아트에서 시도되었던 방법들과 그에 대한 확장된 해석을 통해 과학과 예술을 현대적으로 화합시키는 방법에 대한 연구를 통해 과학과 예술의 수렴을 지향하는 간학제적 관점을 논구하고자 한다.

  • 동아시아의 지역적 정체성은 역사-지리적 실재에 근거할 때 비로소 더욱 성공적으로 대중적 동의를 얻을 것으로 기대된다. 본 연구는 최근에 확대된 장소 개념을 이용하여 동아시아 문화지역의 역사-지리적 설정을 시도하고자 한다. 동아시아 문화지역에 일체성을 부여하는 것은 복수적 장소들이 공유하는 문화적 동질성이 아니라 다양한 공간 규모를 가지는 단일한 장소 내부의 문화적 혼합이다. 문화적 혼합은 지배가 아니면 저항, 그리고 때로는 뒤엉킴의 형태로 표현되는 것이다. "경합 장소로서의 산악"이라는 개념은 동아시아 내부의 문화적 동일성을 탐구하기 위한 실험적 노력의 일환으로 제안되었다. 이러한 장소 개념은 산악을 제외한 다른 공간적 단위-가옥, 정원, 촌락, 도시 등-에 대한 연구들로 확대되어 적용될 필요가 있다. 왜냐하면 이러한 연구들이 축적되면 결국 동아시아가 역사-지리적으로 특정한 문화적 동일성을 가진 장소라는 정의가 구체적으로 가능해질 것이기 때문이다.

  • The basic principles in the "Spleen-stomach theory(脾胃論)" sets up the phases and roles of spleen-stomach (脾胃) by establishing Earth(地 坤 土) and exposing the reality of spleen-stomach(脾胃) of human body which has its own shape and form with Heaven's reality exhibited. The meaning of Earth is based on the constant meaning of Earth in 'Earth Original-Earth as extended and stable ground(坤元一正之土)' giving form and shape, and Earth's movement with circulation, then exposes itself as 'Earth as plowing land(耕種之土)' concerning both the application of Five Phases and the physical characteristics of Earth. The Yin-Yang recognition on Earth is revealed as Yin Earth(陰土)-Yang Earth(陽土). Spleen(脾) was established as Yin Earth(陰土) and Stomach(胃) as Yang Earth(陽土). The seasonal assignment of Earth is Indian Summer(長夏), which is divided from Summer, and becomes Heat(熱), and the Yin-Yang recognition of Earth comes to be the meaning of the center and border. According to the Five Phasic recognition, it becomes Earth(土) and gets to be Dampness(濕) in accordance with Six Qi(六氣). 'Extreme Yin(至陰)' indicates Qi's status exposing the fundamental meaning regarding the role of creating, changing, and propelling Spleen-Stomach(脾胃) as a characteristic Yin Earth. Earth comprehends 'Four Courses(四維)' meaning, recognizes them as four parts of the 12 Earth's Branches(辰戌丑未) and the terminals of four seasons(四季之末), and has the meaning of the president of the change in four seasons. The theory of principle in the "Spleen-stomach theory(脾胃論)" stands on the basis of the 'Form Qi theory(形氣論)' and that of 'Upbearing, Downbearing, Floating, and Sinking theory(升降浮沈論)'. It manifests the theory of movement in the interaction between Form(形) and Qi(氣), and 'Qi Interior Form Exterior(氣裏形表)' indicates that Qi(氣) moves interiorly and Form(形) exteriorly.

  • The Fukushima-Daiichi accident shook the world, as a well-known plant design, the General Electric BWR Mark I, was heavily damaged in the tsunami, which followed the Great Japanese Earthquake of 11 March 2011. Plant safety functions were lost and, as both AC and DC failed, manoeuvrability of the plants at the site virtually came to a full stop. The traditional system of Emergency Operating Procedures (EOPs) and Severe Accident Management Guidelines (SAMG) failed to protect core and containment, and severe core damage resulted, followed by devastating hydrogen explosions and, finally, considerable radioactive releases. The root cause may not only have been that the design against tsunamis was incorrect, but that the defence against accidents in most power plants is based on traditional assumptions, such as Large Break LOCA as the limiting event, whereas there is no engineered design against severe accidents in most plants. Accidents beyond the licensed design basis have hardly been considered in the various designs, and if they were included, they often were not classified for their safety role, as most system safety classifications considered only design basis accidents. It is, hence, time to again consider the Design Basis Accident, and ask ourselves whether the time has not come to consider engineered safety functions to mitigate core damage accidents. Associated is a proper classification of those systems that do the job. Also associated are safety criteria, which so far are only related to 'public health and safety'; in reality, nuclear accidents cause few casualties, but create immense economical and societal effects-for which there are no criteria to be met. Severe accidents create an environment far surpassing the imagination of those who developed EOPs and SAMG, most of which was developed after Three Mile Island - an accident where all was still in place, except the insight in the event was lost. It requires fundamental changes in our present safety approach and safety thinking and, hence, also in our EOPs and SAMG, in order to prevent future 'Fukushimas'.

  • 최근 국내에서 크게 증가하고 있는 아웃도어레크리에이션 열풍은 여가시간과 가처분소득의 증가뿐만 아니라 대중매체와 대중문화의 상호작용의 효과로 볼 수 있다. 국내에서 대중매체를 통해서 노출되는 아웃도어레크리에이션은 실질적으로 크게 증가하고 있고, 관련 산업분야도 급속도록 성장하는 것으로 나타났다. 리얼리티 프로그램 '아빠! 어디가?'의 경우에는 여러 아웃도어레크리에이션을 통해 놀이, 재미, 경쟁, 그리고 일탈적인 특성 등을 사실적으로 노출하고 있기 때문에 관광객의 내재적 특성인 놀이성 측면이 더욱 부각이 된다. 이에 본 연구에서는 대중매체를 통한 아웃도어레크리에이션의 노출이 잠재 아웃도어 레크리니셔트에게 어떠한 영향을 미치는지를 규명하고자한다. 이러한 의사결정과정을 규명하기 위하여 인간의 행동에 대한 설명력이 높은 계획된 행동이론에 성인의 재미와 놀이의 내재적 특성인 놀이성을 추가하였다. 연구결과, 놀이성은 태도, 주관적 규범, 지각된 행동통제에 크게 유의한 영향을 미치는 것으로 나타났고, 태도, 주관적 규범, 지각된 행동통제 또한 행동의도에 유의한 영향을 미치는 것으로 나타났다. 이는 일탈적 행동을 추구하는 아웃도어레크리에이션에서 놀이성이 큰 영향을 미치는 변인임을 규명하였다고 볼 수 있다.

  • The words which appeared in my theoretical study and work are image transformation to digital painting, simulation, heterologie and transfiguration, etc. Firstly, let's look into 'digital era' or 'new media era'. Nowadays, the image world including painting within the rapid social and cultural change, which is called as digital era, is having the dramatic change. Together with the development of scientific technology, large number of events which was deemed to be impossible is happening as real in image world Moreover, these changes in image world is greatly influencing to our life. The word which compresses this change of image world and shows is 'digital'. Digit, which means fingers in Latin, indicates separately changing signal, and to be more narrow, it indicates the continual signal of '0' and ' 1' in computer. The opposite word is 'analogue'. As analogue is the word meaning 'infer' or 'similarity', it indicates the signal or form which continuously changes along the series of time when it is compared to digital. Instead of analogue, digital is embossed as a major ruler along the whole area of our current culture. In whole culture and art area, and in whole generalscience, digital is appearing as it has the modernism and importance. The prefix, 'digital', e.g. digital media, digital culture, digital design, digital philosophy, etc, is treated as the synonym of modernism and something new. This advent of digital results the innovative change to the image world, creates the new beauty experience which we could not experience before, and forecasts the formation of advanced art and expansion of creative area. Various intellectual activities using computer is developing the whole world with making the infrastructure. Computer in painting work immediately accomplishes the idea of painters, takes part in simulation work, contingency such as abrupt reversal, extraction, twisting, shaking, obscureness, overlapping, etc, and timing to stimulate the creativity of painters, and provides digital formative language which enables new visual experience to the audience. When the change of digital era, the image appeared in my work is shown in 'transfiguration' like drawing. The word, 'transfiguration' does not indicate the completed and fixed real substance but indicate endlessly moving and floating shape. Thus, this concept is opposite to the substantial consideration, so that various concepts which is able to replace this in accordance with the similar cases are also exist such as change, deterioration, mutation, deformity of appearance and morphing which is frequently used in computer as a technical word. These concepts are not clearly classified, and variably and complicatedly related. Transfiguration basically means the denial of "objectivity' and '(continual) stagnation' or deviation from those. This phenomenon is appeared through the all art schools of art ever since the realism is denied in the 19th century. It is called as 'deformation' in case of expressionism, futurism, cubism, etc, in the beginning of the century, which its former indication is mostly preserved within the process of structural deviation and which has the realistic limit which should be preserved. On the contrary, dramatic transfiguration which has been showing in the modern era through surrealism is different in the point that dramatic transfiguration tends to show the deterioration and deviation rather than the preservation of indicated object. From this point, transfiguration coming out from morphing using computer deteriorates and hides the reality and furthermore, it replaces the 'reality'. Moreover, transfiguration is closely approached to the world of fake or 'imaginary' simulation world of Baudrillard. According to Baudrillard, the image hides and deteriorates the reality, and furthermore, expresses 'not existing' to 'imaginary' under the name of transfiguration. Certain reality, that is, image which is absent from the reality is created and overflowed, so that it finally replaces the reality. This is simulation as it is said by Baudrillard. In turn, Georges Bataille discusses about the image which is produced by digital technology in terms of heterologie. Image of heterologie is the visual signal which is established with the media. Image of media is to have the continuous characteristics of produce, extinction, and transformation, and its clear boundary between images becomes meaningless. The meaning of composition, excess, violation, etc of digital image is explained to heterological study or heteologie suggested as important meaning of Georges Bataille who is a heretic philosopher. As the form and image of mutation shows the shape in accordance with mechanical production, heterologie is introduced as very low materialism (or bas materialisme), in this theory. Heterologie as low materialism which is gradually changing is developing as a different concept and analysis because of the change of time in the late 20s century beside high or low meaning. Including my image, all images non-standardizes and transforms the code. However, reappearance and non-standardization of this code does not seem to be simple. The problem of transformation caused by transfiguration which appears in my digital drawing painting, simulation, heterologie, etc, are the continual problems. Moreover, the subject such as existence of human being, distance from the real life, politics and social problems are being extended to actual research and various expressing work. Especially, individual image world is established by digital painting transfiguration technique, and its change and review start to have the durability. The consciousness of observers who look at the image is changing the subject. Together with theoretical research, researchers are to establish the first step to approach to various image change of digital era painting through transfiguration technique using our realistic and historical image.

  • A stereo vision is able to build three-dimensional maps of its environment. It can provide much more complete information than a 2D image based vision but has to process, at least, that much more data. In the past decade, real-time stereo has become a reality. Some solutions are based on reconfigurable hardware and others rely on specialized hardware. However, they are designed for their own specific applications and are difficult to extend their functionalities. This paper describes a vision system based on a System on a Chip (SoC) platform. A real-time stereo image correlator is implemented using Sum of Absolute Difference (SAD) algorithm and is integrated into the vision system using AMBA bus protocol. Since the system is designed on a pre-verified platform it can be easily extended in its functionality increasing design productivity. Simulation results show that the vision system is suitable for various real-time applications.

  • The 3D position of pedestrians is a physical quantity used in various fields, such as automotive navigation and augmented reality. An inertial navigation system (INS) based pedestrian dead reckoning (PDR), hereafter INS-PDR, estimates the relative position of pedestrians using an inertial measurement unit (IMU). Since an INS-PDR integrates the accelerometer signal twice, cumulative errors occur and cause a rapid increase in drifts. Various correction methods have been proposed to reduce drifts. For example, one of the most commonly applied correction method is the zero velocity update (ZUPT). This study investigated the characteristics of the existing INS-PDR methods based on shoe-mounted IMU and compared the estimation performances under various conditions. Four methods were chosen: (i) altitude correction (AC); (ii) step length correction (SLC); (iii) advanced heuristic drift elimination (AHDE); and (iv) magnetometer-based heading correction (MHC). Experimental results reveal that each of the correction methods shows condition-sensitive performance, that is, each method performs better under the test conditions for which the method was developed than it does under other conditions. Nevertheless, AC and AHDE performed better than the SLC and MHC overall. The AC and AHDE methods were complementary to each other, and a combination of the two methods yields better estimation performance.
