  • 본 논문에서는 심혈관 조영영상으로부터 좌심실의 형태 및 운동을 가시화하기 위해 기하학적 정보와 물리적 정보를 통합한 동적 가우시안 블럽(dynamic gaussian blob)모델을 개발하였다. 동적 가우시안 블럽 모델은 superellipsoid에 3차원 가우시안 형태함수를 갖는 단일 유한요소를 통합한 것으로, 좌심실에 작용되는 가상적인 힘에 의해 형태를 적하하고, 심박동 전 주기에서의 운동을 추적한다. 또한 벽 운동 정도에 따라 다른 색을 지정하여 볼 수 있도록 함으로써 벽 운동에 이상이 있는 부위를 육안으로 쉽게 판별할 수 있도록 하였다. 이와 같은 좌심실의 동적.색체 가시화는 형태가 변황되는 심장질환이나 허혈이나 심근경색증처럼 심실벽 운동에 이상이 있는 질환의 진단을 도울 수 있다.

  • Through advanced computer technology, our physical environment became a flexible and liquid space that is a multi-functional space structure, hetero-alliance, formless, interactivity. We attempt to interpretate Deleuze's Other geometry as a space designer. Hence first, the aim of this study is to define the meaning of the Other and Other geometry. Second, to extract keywords out of the Other geometry to analyze the work. Third, to analyze the work using the space formative languages(blob, blurring, distortion, folding, layering, lightness, nesting, repetition, shear, transparency, twisting, unfolding, warping, waving, and weaving). The 13 works were selected which have been issued after year 2000 with the focus on liquid space studies. The methods of this study are literature research and contents analysis. The results of the analysis were as follows. First, the source is the Other who is a hidden potentials in the surrounding environment, and this source has the capability of making it part of reality anytime. Other geometry means it is a theory that is comprised of various lines that with the kind of experiences that one has in life. Second, the key words that were extracted from the theory of Deleuze's Other geometry were of (1)hetero-alliance(reflected in a sculptured shape or a fluid abstract form), (2)dis-form(by speculating the user's movements, and combining space elements with external forces), (3)interactivity (information was exchanged real time between the user and his environment where the space took on a sensory institution). Finally, after studying the works using the space formative languages, we found that blob, warping, waving were used externally, and repetition, warping and waving for mostly used internally.

  • Spatial multiplication phenomenon, expressed through de-constructive trend since the late of 20C, have got changed existing fixed and dis-variable space to smooth, fluid, and changeable space. Ex-form and fluidity of new spatial paradigm have been focused through lots of scientific theories studied between digital thought and indeterminacy and rankless nature phenomena. In 21C fashion, indeterminate and irregular form and space have been crested continuously, which could not explain simply according as the fluidity theory Different from the space crested for multi-function and multipurpose, this is revealed the characteristics of chaosmos that communizes the order and the disorder, deconstruction and creation. Ex-formal space of fashion have shown the relationship of de-centerizing, de-territorial, and do-structural phenomenon among different fashion elements. This paper intends to understand the concept of ex-form, and study expressive manners of ex-formal space of 21C fashion, and conclusion as follows. 1) Overlap changes single space of fashion to multi-layered space through the repeat system of pleats, origami, and folding. 2) Ex-gravity expressed in deviation of the gravity acting vertical direction, for example, twisting, curve, winding, portion. 3) Morphing is shown the change process from single fixed form to different complex form. 4) Blurring is expressed in re-combination and re-arrangement among elements of fashion. 5) Blob shows hybrid fashion space through the liberal compounding and separation of a lot of different elements.

  • 본 연구의 목적은 전통적인 니트웨어에 대한 의미와 깊이를 파악하고 베르그송과 들뢰즈의 연속성 이론을 배경으로, 전통 니트의 대표적 패턴인 아란 모티프를 응용한 니트웨어의 디자인 전개와 개발을 해보는데 있다. 현대패션에서 보여지는 주름, 종이접기, 공기주입시스템, 방울이나 꼬임 등에서 느낄 수 있는 소통, 공간적 느낌, 해체적 유동성 등이 연속성 이론의 기본이 된다. 아란 니트는 역사적 전통성을 가지고 있으며, 아란 니트에서 보여지는 모티프는 이러한 연속성의 이론에 부합하고 있다. 본 연구에서는 아란 모티프에서 연속성의 대표적인 케이블 모티프와 연속성 이론을 바탕으로 5점의 핸드 니트웨어를 디자인, 제작하였다. 전통적인 아란 니트와 연속성이론에 기초한 작품 제작 결과를 통하여 새로운 의미를 전달할 수 있는 니트 디자인 개발이 지속적으로 이루어지길 바란다.

  • The development of fluorescence microscopy of single-molecule DNA in the last decade has fostered a bold jump in the understanding of polymer physics. With the recent advance of nanotechnology, devices with well-defined dimensions that are smaller than typical DNA molecules can be readily manufactured. The combination of these techniques has provided an unprecedented opportunity for researchers to examine confined polymer behavior, a topic far less understood than its counterpart. Here, we review the progress reported in recent studies that investigate confined polymer dynamics by means of single-molecule DNA experiments.

  • The objective of this research is to suggest new geometric possibilities in digital architecture by investigating the characteristics of hybridization in digital geometry. The research begins with theoretical background research such as defining hybridization, investigating hybrid thinking, and studying the theory of digital geometry, along with the four conceptual characteristics of hybridization that could be drawn, such as temporality, liquidity, complexity, and connectivity. Based on these characteristics, the generative method of hybrid digital geometric languages such as Blob, Particle, Morph, Loft, and Boolean was analyzed with case research in contemporary digital architecture. As a result, diverse hybrid geometric keywords were extracted; these keywords suggest potential meanings of hybridization such as accidentality, mobility, diversity, and identity. Different elements represent the "mobility" in time by the force and wave, and they are "accidentally" combined in gradual change. The united species in "diverse" characters are seamlessly connected and emerge as a new "identity." The research maximizes the generative possibilities in digital geometry and provides a theoretical basis to apply the digital hybrid methods to architectural design by suggesting the potential meanings and possibilities in hybridization.
