The operating window method is a novel approach in quality improvement. But it has not received deserved attention in academic research. If a critical factor for competing failure modes can be identified, the probability of failure can be reduced by widening the operating window of this factor. Traditional SN ratio for the operating window advocated by Taguchi has a critical shortcoming, which has been derived under the assumption that failure rates are determined by the operating window factor only. A new metric for robustness is given for the operating window method, which has relaxed the restrictive assumption of Taguchi's SN ratio. And procedures for determining optimal conditions based on the new metric is presented. The effectiveness of the proposed approach over the traditional practice is tested with the aid of a wave soldering process.

This research analyzes trends of fashion show window displays, regarding it as a new form of installation art that has the characteristics of contemporary art. Fashion show window displays are more than a physical space for displaying and have emerged as a new space in which creative expressions of arts take place. This research presents the characteristics of contemporary fashion show window displays by analyzing the characteristics of contemporary art. First, recent show window displays have shown "decentralization": various themes, forms, and mediums that are accepted without discrimination. Recent show window displays deviate from conventional methods, constantly pursuing experimental and progressive ideas and also include categories of current art, body art, and live art. Second, show window display has "interactiveness" that enables two-way communication between audiences and art, rather than fixing audiences as receptive viewers. Third, "textuality" can be found in show window displays. Recent show windows are use "objects" to show products as well as to express the meaning and symbols of products. A new directionality and effective strategies are shown to be imperative for the future development of fashion show window displays.

현대산업사회의 발전에 따라 신호처리 분야 중 디지털필터의 사용은 급격히 증가하고 있으며, 특히 디지털 영상처리, 디지털 음성처리, CATV 및 각종 통신 분야 등에서 카메라의 Detail processor, Y/C separator, Ghost제거 필터, 표준변환기(NTSC-PAL), Noise reducer 등으로 많이 사용되고 있다. 이러한 디지털필터에는 일반적으로 IIR(infinite impulse response)과 FIR(finite impulse response) 필터가 있으며, 본 논문에서는 구현이 용이하고 선형위상특성을 갖는 FIR 디지털필터를 설계하였다. FIR 디지털필터 설계에 있어서 통과대역의 차단주파수 부근에서 깁스(gibbs) 현상에 의해 생긴 리플을 완화하기 위해 window함수를 사용한다. 그러나, 기존의 window는 고정된 값으로 되어 있으므로 설계목적에 적합한 window함수를 선택함에 있어 다소 문제점이 있다. 따라서, 본 논문에서는 설계목적에 따라 서 융통성있게 선택이 가능한 파라메터를 부가한 변형된 Hanning window를 설계하였으며, 타당성을 입증하기 위해 디지털필터를 설계하여 기존의 Hamming, Hanning, Blackman, Kaiser window와 비교하였으며, 판단기준으로 peak side-lobe와 천이특성 등을 사용하였다.

Conventional window cleaning method has a number of limitations, for example, workers dependent and high crash risk. The purpose of this study is to derive the performance requirements of a window cleaning apparatus through technology survey. For this, we investigated the domestic and international patents related to window cleaning, and interviewed experts in the field of window cleaning and mechanical design. Through this research, we have proposed performance requirements of the window cleaning apparatus.

Growing use of entire glass facades with metal frames are popularly witnessed in modern building practices and design competition as well. In spite of architectural aesthetics and view to outdoors, environmental issues still exist in that kind of buildings. One of the solutions for the problems might be the use of functional glasses such as a heat-resistant glass or various tinted glasses for the glass walls. This paper aims to provide performance data related to the impact of various transmittal materials of window systems on the light distribution. A series of computer simulation deals with the basic geometrical and optical design elements of a commonly used all-glass facades. Additionally an experimental configuration of the vertical window is proposed for better result of daylighting. A window system equipped with an inner-light shelf can improve the uniformity of natural light in a space by reducing the level of illumination near the window and redirecting light deeply into the space.

Show window display is a technique of arranging goods for sales promotion, namely, motivating and inducing customers to purchase products. It is not simply exhibiting articles but a technical expression of values retained in exhibited articles and an integrated visual art comprehending color, lighting effect, the customers' angle of vision, differentiation from neighboring stores, harmony with properties, assistive roles of relevant goods, and entire messages provided by these elements. Show window display plays the role of a medium that expresses brand images and attracts consumers. Through the medium, the company's brand image is recognized and the recognition determines the trend of brand sales. Brand images planted to consumers seldom change, and wrong recognition affects not only the brand image but also the company image. The present study purposed to suggest show window display employing brand images different from traditional show window display, to examine the effects of brand images on consumers' intention to purchase, and to propose display design.

Window is the most demanding design component in the building design. Recently, window area in the building surface has been increased significantly in the office building. As window area increased significantly, however, the thermal load has been increased significantly due to lack of thermal performance of the outside wall. In this paper, we discussed the energy consumption of the buildings according to window area ratio. Two types of building for energy consumption analysis were made by Designbuilder v.1.4 and Energyplus v.2.0. Window area ratio was five different types ($30%{\sim}70%$) in each building. As a result, the cooling energy consumption has been decreased as window area decreased in each building. Whereas the heating energy consumption has been increased window area decreased.

This study identified characteristics of Christmas window display, which is one of visual marketing methods used in department stores, using cases of department stores in Seoul and the New York and to compare the characteristics between Seoul and New York department stores in order to extract the directions and components of window display in each country. Based on the photographs of Christmas window display at the sampled Seoul and New York department stores, we analyzed the window display of each department store. From the results of analysis were drawn conclusions as follows. First, as to the direction of Christmas window display design in Seoul and New York department stores, window display was designed using various themes according to the characteristic of each department store. In case of Seoul department stores, however, specific luxury brands linked to the characteristics of the department stores displayed their products separately, but in New York department stores, various Christmas themes, images related to the department stores, and products were displayed together according to the characteristic of the department stores. Second, among display components, the formative structure and the frequency of mannequin use were different between Seoul and New York department stores. Various formative structures and diverse mannequins used in the window display of New York department stores played the role of stamping the brand image of each department store and exhibiting various designs through window display.
