This study investigates the multi-dimensional structure of fashion store window creativity and examines its effects on consumer responses. Through an expert evaluation survey, this study proposes that fashion store window creativity involves originality, relevance, and artistry. Two experiments are conducted to test the proposed hypotheses. Consumers' emotional responses to the level of window creativity are collected using psychophysiological and self-report methods. Fashion store window creativity has positive effects on psychophysiological affective responses. When the three dimensions of creativity are specified as explanatory factors of emotional responses, relevance and artistry show positive effects on arousal and pleasure, whereas originality has a negative effect on pleasure. Its effect on attitudes is mediated by arousal and pleasure; in addition, the effect on entering intentions is mediated by arousal. Attitudes toward window display also have a positive effect on entering intentions. This study extends existing research on creativity in marketing into the context of visual merchandising in fashion store windows. Findings provide meaningful implications in that the effects of fashion store window creativity on emotions affect consumer attitudes and behavioral intention. By adopting multiple approaches in the empirical phase of this study, the findings are built on strong reliability and validity.

In this paper, a new window model for designing FIR digital filter is suggested. For the suggested model, two parameters are established and their effects to the characteristics of filter are analyzed. As a result, one of these parameters improves the characteristics of the transient region but degenerates those of peak sidelobe a little bit, and the other contrasts the characteristics with the former. These effects of parameters give selectivity to design window. Therefore the new suggested window model gives flexibility to filter design and its improved characteristics is comfirmed by simulation.

The tightness of windows have devoted to the improvement of thermal insulation and energy saving in buildings. But it is known that this tightness causes some side effects such as low ventilation, low capacity to humidity and temperature control and these are not profitable for inhabitants. To act on these side effects, Korean traditional windows which are composed of Han-Ji(Koreand traditional paper) and Chang-Sal(Korean traditional wooden frame) have been studied to get a reasonable solutions for these problems. In this study, to compare the thermal and humidity control performance of current window(12 mm pair) and Korean traditional windows, frames which are made of existing window and Korean traditional windows are adapted to scale model house and then humidity and temperature of in and out of scale model house are measured and analysed. The results of this study are followings ; 1) When Korean traditional window charges 20cm(1/8 of total window area) from total window area, Han-Ji window has higher thermal insulation than that of existing window in daytime. There is the most big thermal difference when double faced with double-ply Han-Ji window is placed to mock-up house. In night-time, the temperature difference is very small so this means that Korean traditional window is good to cover direct sunlight in daytime and reduce the temperature of balcony. One faced with one-ply han-Ji window has the best humidity penetration performance among three type of Korean traditional windows. 2) When Korean window area enlarged to 40cm(1/4 of total window area), the function of 40cm width Han-Ji window is higher than that of 20cm's. This means that enlargement of Han-Ji window cover direct sunlight more and is more efficient in humidity penetration.

The purpose of this study was to examine the effects of VM components(facade color and show window type) on store image and purchasing intention of fashion stores. The subjects were 428 male and female university students in Daejeon and Chungnam province. The measuring instruments were 6 stimuli manipulated by $3{\times}2$ factorial design of facade color and show window type, and a self-administrated questionnaire consisted of store image, purchasing intention, and subjects' demographic characteristics. The results were as follows. First, facade color mainly affected store image and purchasing intention. White color was preferred as more positive images(pleasurable, comfortable, neat, and modern), and showed higher purchasing intention than brown color. Second, show window type affected some store images. Semi-open type was perceived as more pleasurable image than enclosed type, whereas enclosed type was perceived as more luxurious, neat, and attractive image than semi-open type. However, show window type didn't affect purchasing intention. Third, subject' sex affected store image and purchasing intention. Male subjects perceived more positively on store image and had higher purchasing intention than females. This study suggested that facade color and show window type are important VM components affecting store image and purchasing intention.

The present study demonstrated the effects of processing variable and alloying elements on the processing window of austempered cast iron, one of the heat-treatable cast irons, in order to elucidate the relation between heat treatment and microstructure in terms of time and temperature. Such microstructure is strongly affected by austenitizing conditions and alloying elements. The size of processing window tends to increase initially with increasing austenitizing temperature from 1123 to 1173 K, followed by a decline in the reverse direction between 1173 and 1223 K. Thus, the optimized processing window with large frame was found at an austenitizing temperature of 1173 K. To determine the effect of Sn addition, the processing window in the sample was created by the addition of 0.08 wt.% Sn, which appeared larger than that without Sn and with 0.06 wt.% Sn.

Daylighting affects the luminous environment and provides comfortable environment to the occupants. However, excessive daylighting might have negative influences on the visual comfort. Skylight, light intensity and distribution, and insolation could cause glare effects on the occupants. This study analyzed the effect of fenestration on the interior glare effects, and verified luminous environment adjustability through mock up test of conventional fenestration and 'Convergence Window System' by analyzation of luminance, luminance contrast, and glare effect. Consequently, room installed Convergence Window System was improved luminance contrast and PGSV Level.

The fundamental purpose of this study is whether Show Window Display actually affect on purchase and if it does, how much Show Window Display have influence on the buyer's satisfaction. Show windows are most important at clothing stores. The show open types of domestic clothing stores are usually open-type and semi open-type. Show Window Display types of low and middle prices stores are generally opened, horizontal and storied type and the shape, height, opening type and use of ground floor are different by regional distinct features. Generally Show Window Display are consisted by lights, mannequins and directed props. In buying patterns, an impulse buying has more stronger effect than a scheduled buying, a substituted buying and non-buying. An impulse buying are strongly affected by Design and others are prices. The reason why Show Window Display affecting on purchase is the satisfaction of Design and the strong stimulus to purchase(impulse buying), and then Show window Display used by all components strongly has an effect on it. Factors of purchase desires were Design, price and quality in order and factors of purchase motivations were the motivation of clothing design and the motivation of impulse buying. Thus the effects of Show Window Display and factors of purchase motivations are same. As a result of this study, differentiated Show Window Display methods of clothing stores affect the value of goods, the stimulus of purchase and fostering sales effectiveness. Therefore the instruction of Show Window Display methods are indicated by this study.

The effects of austempering temperature, austenitizing temperature and time, added copper content and prior heat-treatment on the processing window of 3.6wt%C-2.5wt%Si ductile cast iron during austempering. The maximum processing window was obtained at 350℃ of austempering temperature. The processing window was increased with increased austenitizing temperature from 850 to 900℃; however, it decreased at 950℃. The processing window was increased with increased austenitizing time from 0.5 to 2 hours and rather decreased for 4 hours. The optimum condition of austenitizing was obained at 900℃ for 2 hours. The processing window was increased with copper content added in the range of 0.0~0.8wt%. The processing window was increased by prior normalizing heat-treatment and decreased by prior annealing in comparison with that for the as-cast state,

Wigner-Ville distribution which is a time-frequency analysis has a fatal drawback, when the signal has multiple components. This is the cross-talk and often causes a neagative value in the distribution. Wingner-Ville distriution is an expression of power, therefore the cross-talk must be avoided. Smoothing the Wigner-Ville distribution by convoluting it with a window, is most commonly used to reduce the cross-talk. There can be infinite number of distributions depending on the windows. But, the smoothing reduces resolution in time-frequency plane; this motives to design a more effective window in reducing cross-talk while remaining resolution. The domain in which the cross-talk and legitimate components can be easily distinguished, is the ambiguity function. In the ambiguity function domain, the legitimate components appear as linear lines passing through the orgine. But, the cross-talk is widely distributes in the ambiguity function plane. Based on the relative distributions of cross-talk and legitimate components, rotating window can be designed to minimize cross-talk. Applying the rotating window to the ambiguity function corresponds to smoothing the Wigner-Ville distribution. Therefore, the effects of rotating window is estimated in terms of the bias error due to smooting the Wigner-Ville distribution. By applying the rotating window, not only the Wigner-Ville distribution but also its properties are changed. The properties of the new distribution are checked, in order to complete analyzing the rotating window.
