3차원의 세계를 작품으로 구현해내려는 시도는 시대와 매체를 구분하지 않고 계속되어왔으며, 그 목적은 현실의 재현보다도 몰입 상태의 구현이다. 본 연구는 디지털미디어아트에서 최종적으로 관람자와 마주하는 매체인 평면스크린이 완전한 몰입을 방해한다고 보고, 스크린의 한계를 벗어나 공간의 현실감을 주는 작품들의 사례를 조사하고 분석하였다. 분석한 결과를 작품 제작에 활용한 결과, 디지털미디어아트 분야에서 현실적 공간의 제시와 몰입의 강화는 스크린 내의 시각적 영상 콘텐츠뿐만 아니라 전시 환경에 맞는 설치, 결과적으로 구성되는 공간 그 자체까지 작업으로 보아야 한다는 것을 알 수 있었다.

The purpose of the present study is to figure out what the issues faced by architecture were at the time immediately before the transition to modern era centering of the works of Otto Wagner who acted in Vienna, Austria at the Fin de $si{\grave{e}}cle$. Therefore, the following points were examined in the present study; first, how were new spaces necessary to accommodate modern lives organized and how were the plans changed; second, how did the external expressions of architecture pursued by Otto Wagner appeared between arts and technologies, between historicism and modernity, and between decorations and functions. Through the study, it could be seen that Wagner began from historicism and traditionalism and tried to compromise them with modernity. Many modern characteristics appeared a priori in Wagner's works from the construction of 'Linke Wien Zeile housing block' in 1898, his works completely broke from the typical historicism styles to open the period of inventive 'Secession styles.' At that time, Wagner concentrated on so called 'flat decorations.' Thereafter, his residential architecture completed to modern styles with 'Neustiftgasse housing block' as the peak. The characteristics of modern housing as above became a cornerstone of the modern functionalism later.

비정형 텍스트 문서를 다중 범주로 분류하는 문제에 있어서, 계층적 분류 방법이 비계층적 분류 방법에 비하여 분류 성능이 우수한 것으로 알려져 있다. 기존 문헌과 다르게 본 연구에서는 사전에 범주들의 계층 구조가 정의된 상황에서 계층적 분류 방법과 비계층적 분류 방법의 성능을 비교하였다. 수자원 분야 기후변화 적응기술과 관련한 논문 분류 데이터와 20NewsGroup 오픈 데이터를 대상으로 계층적/비계층적 분류 방법의 성능을 비교하였다. 본 연구결과 기존 문헌과 다르게 계층적 분류 방법이 비계층적 분류 방법에 비하여 언제나 성능이 우수한 것은 아님을 확인하였다. 계층 구조의 상위/하위 수준에서의 상대적 유사도에 따라서 계층적/비계층적 분류 방법의 성능에 차이가 있음을 확인하였다. 즉, 상위 수준의 유사도가 하위 수준보다 상대적으로 낮은 경우 상위 수준에서의 오분류 감소로 계층적 분류 방법의 성능이 개선됨을 확인하였다.

A novel flatness sensing system which is called the Flatness Sensing Inter-stand Looper(FlatSIL) system is suggested and a self-tuning PI control system using the FlatSIL is designed for improving the flatness of hot strip in finishing mill processes. The FlatSIL system measures the tension along the direction of the strip width by using segmented rolls, and the tension profile is approximated through the tension of each segmented roll. The flatness control system is operated by using the tension profile. The proposed flatness control system as far as the tension profile-measuring device works for the full strip length during the strip rolling in finishing mills. The generalized minimum variance self-tuning (GMV S-T) PI control method is applied to control the flatness of hot strip which has a design parameter as weighting factor for updating the PI gains. Optimizing the design parameter in the GMV S-T PI controller, the Robbins-Monro algorithm is used. It is shown by the computer simulation and experiment that the proposed GMV S-T PI flatness control system has better performance than the fixed PI flatness control system.

This study applied cartoon-like simple and implicit symbol of Keith Haring works to tubular jacquard knit, designed woman casual knit wear with fun, explicit and activities using fluorescent yarns with explicit features. This study aimed to propose the directions for new market pioneering that meets the emotional requirements of modern people by raising the level of utilization and expression area of knit fashion, and to present the constructive directions for high value-added knit wear by designing highly effective knit wear. Methods of this study examined the lifetime and artistic background of Keith Haring and collected his works through searching of internet, scholastic publications or thesis. Formative types and colors of works collected were analyzed and classified according to characteristic standards of Haring and characteristic formativeness and color of works were extracted. The result of this study is as shown below: First, the feature of his works can be summarized into motif that has symbolic and implicit cartoon-like lines including narratives as well as enormous number of works. Such feature is very suitable for variation and recombination in realization of design and has unlimited potentials for development. Second, image colors can be extracted such as black and white, original color and fluorescent paints, which reflects the intention of artist who put focus on communication with the public. Such color feature is very suitable for design motif that has explicitness of reflecting the intention of artist through use of special fluorescent yarn. Third, I made it as reversible wear that has effects of increasing or decreasing the explicitness according to color area ratio using the feature of textures allowing use of both sides as well as form stability of tubular jacquard. Fourth, by adjusting the thickness of fabric with controlling of ply in fabric using poly yarn and wool union yarn, I could obtain good results of study in terms of technique that can express various materials with embossed dynamic effects of unevenness on flat surface.

To understand the basic relationship between 3D curved surface model and 2D pattern, simplified torso model was generated by commercial CAD program (IDEAS). 3D torso model was then divided into different blocks and unfolded into a flat pattern as in ordinary works of clothing item design. As results, 2D pattern development of different part of 3D torso model was attempted and analyzed mathematically. It was found that different height, radius and tangent slope of 3D blocks resulted in different 2D pattern. The relationships between the shape parameters of 3D torso blocks and those of 2D patterns were analyzed using regression equations. Direct way of drawing a 2D pattern of corresponding 3D torso block was also illustrated for the convenience of pattern making using conventional measurements of upper/ lower radii and height of 3D torso block.

A mathematical model for investigating the form generation mechanism in the centerless infeed grinding process is described. For 3-D modeling of form generation, contact points are assumed to be on least squares contact lines at the grinding wheel, regulating wheel, and work-rest blade. Using force and deflection analysis, the validity of this assumption is shown. Based on the 2-D simulation model developed in the previous work and the least squares contact line assumption, a 3-D model is presented. To validate this model, simulation results were compared with the experimental works. The experiments and computer simulations were carried out using three types of cylindrical workpiece shapes with varying flat length. The experimental results agree well with the simulation. It can be seen that the effect of flat end propagated to the opposite end through workpiece reorientation.

최근 시공의 합리화 및 공기단축을 위하여 많은 PC공법이 개발되어져 왔다. 그러나 이러한 PC공법은 접합부의 보강 및 현장 조립시에 많은 노력을 요구할 뿐만 아니라 위험요소도 내재하고 있다. 따라서 이상과 같은 PC의 단점을 보완함과 동시에 PC의 장점을 그대로 살릴 수 있는 중공 PC기둥을 제안하여 본다. 본 연구에서는 플랫 플레이트 슬래브와 중공 PC기둥 접합부의 연성능력에 대해서 기존의 RC기둥을 사용한 경우와 비교 분석 하였다.

A computer simulation method for investigating the form generation mechanism in the centerless infeed (plunge) grinding process is described. For a 3-D simulation model of form generation, contact points are assumed to be on least squares contact lines at the grinding wheel, regulating wheel, and work-rest blade. Using force and deflection analyses, the validity of this assumption is shown. Based on the 2-D simulation model developed in the previous work and the least squares contact line assumption, a 3-D model is presented. To validate this model, simulation results were compared with the experimental works. The experiments and computer simulations were carried out using three types of cylindrical workpiece shapes with varying flat length. The experimental results agree well with the simulation.

This paper presents the novel fabrication of an electromagnetic micro actuator with a corrugated diaphragm and a flat one. The actuator consists of a Parylene diaphragm with a spiral copper coil and a permanent magnet. The cower coil is fabricated by electroplating and patterning. As the further works, the frequency response of the actuator are obtained by using a laser vibrometer and the static deflection of the actuator diaphragm are measure by using laser displacement meter. The corrugated diaphragm is expected to be better than the flat one with respect to the actuator performance.
