Today, the convergence of fashion design and digital technology has become a popular method and accordingly been tried variously in the fashion area. This study aimed to analyze the character of the collaboration with fashion and technology, and the meaning of technology as emotional expression methods. Selected designer's collections, literature and other related studies were reviewed in order to analyze the generative structure of the meaning and the binary-opposition in the convergence of body, fashion design and technology. Literatures and selected designer's collections were reviewed and quantitatively studies were performed to classify the convergence of human bodies, fashion design and technology through Greimas Semiotics rectangle based on binary-opposition of meaning and isotophy analysis. The research presents three types of fashion technology methods: mechanical movement, light/digital media, and virtual image. The convergence of fashion and technology was classified as the direct convergence and the indirect convergence. The direct convergence was characterized by variability and has automatic, independent movement, but the indirect convergence was shown closed and to have contradistinctive images.

Stress induces change to the body functions and causes chronic problems such as worsening a disease. Thus, humans want to evade anxiety and would try any means to reduce stressful situations. Generally, a person would handle their stress by either regulating their emotions or merely coping with the situation, for which the former is most widely used. Our research aims to effectively reduce stress by using the emotional response structure developed by Plutichik and the vitalization method. We extracted the relevant components of the stress-reduction method that would be applicable in any space using digital technologies such as sensors, IoT, and augmented reality. An architect or designer may incorporate these structural components into any structure to effectively reduce people's stress. The research aims to provide a new perspective of architectural space and to show applications of the stress-reducing architectural spaces, which should also fulfill the people's needs. Further research is needed to develop an automatic system to utilize spatial components more effectively.

In order to implement the digital PID control algorithm, it is necessary to consider the effect of the finite word length(FWL). In this paper, we show the FWL effect in the digital PID controllers. The conception analyse the effects of the signal quantization error in the digital PID algorithm and the coefficient wordlength determined from performance criteria with the statistical wordlength concept. Throughout this paper, it is dealt with the type of controller structure based delta operator the delta operator has such advantages are superior rounfoff noise perfoff noise performance, more accurate coefficient repersentation, and less sensitive control law.

A semicustom VLSI design fo digital filters used in TDM/FDM transmultiplexer is described. A filter bank composed of only all-pass digital filter sections are implemented with the polyphase network. The use of all-pass filters as basic building blocks is shown to provide a trans-multiplexer structure that has low computational requirements, low quantization noise, and high modularity. The silicon compiler system is used to reduce the design time and to increase the credibility of designed filters. As a prototype, 1st and 2nd order all pass filter are designed, using CMOS N-well double metal technology. The chip sizes of first order filter and the second order filter are 2652 x 533\ulcorner\ulcorner 5334x4300\ulcorner\ulcorner respectively.

최근 디지털 기술의 급속한 발전은 정치, 경제, 사회, 문화 등 우리 사회의 거의 모든 분야에 엄청난 영향을 미치고 있다. 우리가 살고 있는 도시가로는 역시 예외는 아니다. 디지털 기술의 발달은 도시가로의 물리적 구조와 성장 패턴, 그리고 그동안 도시가로가 수행해 왔던 기능과 역할을 새롭게 변모시키고 있다. 지금의 도시가로는 그동안의 합리적이고 효율적이라는 목적아래 추구되어 온 똑같은 모습의 기능주의 적인 형태에서 벗어나야 할 때이다. 디지털 기술을 도시가로에 공간적으로 담아내고, 동시에 그 문화의 생성과 지속을 위해, 현재 우리가 살아가고 있는 도시공간의 구체적 맥락 속에서 독특하게 형성되고 있는 디지털 생활양식, 즉 디지털 도시가로문화에 대한 성찰이 필요하다. 본 연구에서는 도시가로에서의 가로의 기능을 -최근 디지털기술의 발전이 새로운 형태의 교류의 장을 열게 되는데 따른-인간을 위한 소통의 중심지로 보고자 한다. 또한 디지털 기술로 인해 앞으로의 도시가로의 물리적 환경은 어떠한 형태와 기능으로 진화해 나갈 것인가에 관심의 초점을 두고, 아울러 이러한 도시의 진화를 선도해야 하는 도시계획 및 환경디자인 분야가 디지털 기술을 어떻게 수용해야 하고, 앞으로 어떠한 역할을 담당해야 할 것인가를 살펴보고자 하였다.

This paper describes a design for a RF receiver to receive satellite digital audio service. The RF receiver designed in this study is a planar structure that is easy to install on the rooftop of a car and is compact in size. In addition, it can be applied to certain commercial models because it has low noise and high gain characteristics. The impedance bandwidth of antenna is 17.8%(415MHz), and the axial ratio is below 3dB as good properties for the bandwidth of 40MHz which is a satellite digital audio service band. Also, it had a broad radiation beamwidth of $95.41^{\circ}$ in H-plane and $117.45^{\circ}$ in E-plane. From the results of the field test of satellite digital audio service reception for the RF receiver, it demonstrated good C/N rate(10.2dB).

본 논문에서는 PLA를 사용하여 디지털논리 스위칭함수를 효과적으로 구성하는 방법을 제안하였다. 제안한 방법은 먼저 포스트 대수를 기반으로 MIN 대수연산과 MAX 대수연산을 제안하였고, 이를 구현하기 위해 T-gate에 대해 논의하였다. 그리고 PLA의 기본 회로인 MIN 배열, MAX 배열과 리터럴에 대해 논의하였다. PLA를 사용하여 디지털논리스위칭함수를 설계하기 위해 변수분할, 모듈러 구조, 리터럴 생성기, 복호기와 인버터를 제안하였다. 제안한 방법은 좀 더 콤펙트하고 확장성이 용이하다.

In general, the solvability of linear robust output regulation problem are not preserved under time-sampling. Thus, it is found that the digital regulator implemented by itme-sampling of anlog output regulator designed based on the continuous-time linear system model is nothing but a 1st order approximation with respect to time-sampling. By the way, one can design an improved sampled-data regulator with respect to sampling time by utilizing the intrinsic structure of the system. In this paper, we study the system structures which it is possible to design an improved sampled-data regulator with respect to sampling time.

A control of nonlinear system is motivated by the fact that all real plants are nonlinear systems and model identification introduces parameter errors. The purpose of this study is to design a Discrete Variable Structure Controller(DVSC) for single-rod hydraulic cylinder system. The model contains uncertain parameters which we known to lie upper and lower bounds. In the design of DVSC, the boundary layer concept was adopted to reduce cattering. The DVSC was evaluated through digital computer simulation and compared with a VSC (analog controller).

In recent years, dramatic advances in information technology have motivated the construction industry to improve its productivity. Computer-based information technology includes Computer-Aided Design (CAD), Computer-Aided Engineering (CAE), Computer-Aided Manufacturing (CAM), Enterprise Resource Planning (ERP), Digital Mock-Up (DMU) and Product Data Management (PDM). Most construction industries are trying to apply these technologies for quality improvement, reduction of construction time and cost. PDM is very useful for managing data and process related to product design and manufacturing. PDM system has various functions such as drawing and engineering document management, product structure and structure modification management, part classification management, workflow management, and project management. In this paper, PDM system was applied to the design of steel-concrete composite girder bridge. To make a practical guidance for PDM implementation to bridge design, the procedure for its implementation was presented. Consequently, this paper could be useful to enhance the efficiency of bridge design.
