The main purpose of this research is to examine what are the factors that affect consumer attitude by the types of clothing window display, and find if there is any difference by gender of consumer group. Total 357 data from random sample of 347 adults(156 male and 191 female) who were between 19 to 49 years of age were analyzed. Sources for the sample were companies and apartment complexes and several colleges in Seoul and Chonan to diversify by such demographics as age and social status. Factors were measured by respondents' rating of 9 statements using a 5-point Likert-type scale. SPSS(Statistical Package for Social Science) Version 10.0, is used for factor analysis in order to comprehend the factors of consumer attitude and Cronbauch's ${\alpha}$ in order to measure the credibility of questions in each factor. The main findings are as follows: First, three dimensions of consumer attitude to two types of window-display of product centered display and image centered display were identified as interest, information, and impression and theses are same to both male and female consumer group. Second, for both male and female consumer group, three dimensions of consumer attitude toward two types of window-display were same, however, included sub categories in each dimension showed a little difference. In product centered display, both male and female consumer group showed high interest in the sub categories of 'fashion' and 'informations related to the product' and they were considered same factor. Otherwise, In image centered display, two sub categories of 'having some interests in the display' and 'recognize the display that projects the image or impression of clothing well' were showed high relationship each other and they were also considered same factor. Third, Cronbauch's ${\alpha}$ of three dimensions of consumer attitude demonstrated high credibility from 0.75 to 0.91. Mean score of subcategories of attitudes toward the type of display by the gender of consumer showed high scores of 'interest' and 'impression' categories in image centered display and showed high scores of 'information' category in product centered display for both gender.

The purpose of this study was to examine the effects of retail area image and shopping mall image on consumer behaviors in the retail area and in the shopping ma]1. Data were obtained from a survey to a stratified sample selected at the exits of five different malls. A total of 740 questionnaires were distributed, and 661 responses were analyzed. Stepwise regression analysis revealed that two retail area image factors of variety of stores and atmosphere significantly affected all three consumer behaviors (shopping, service facility visits, social activities). Stepwise logistic regression showed that facility and atmosphere of the retail area image and product & service and convenience of the fashion shopping mall image affected seven consumer behaviors in the shopping mall. The results indicate that the retail area image as well as the shopping mall image affects a variety of consumer behaviors in the shopping mall though no shopping mal1 image affects behaviors in the retail area.

In this paper, an optical image hiding technique using real-valued decoding key is proposed. In the embedding process, a each zero-padded original image placed in a quadrants on an input plane is multiplied by a statistically independent random phase pattern and is Fourier transformed. An encoded image is obtained by taking the real-valued data from the Fourier transformed image. And then a phase-encoded pattern, used as a hidden image and a decoding key, is generated by the use of multiple phase wrapping from the encoded images. A transmitted image is made from the linear superposition of the weighted hidden images and a cover image. In reconstruction process, the mirror reconstructed images can be obtained at two quadrants by the inverse-Fourier transform of the product of the transmitted image and the decoding key. Computer simulation and optical experiment are demonstrated in order to confirm the proposed technique.

This paper addresses the central issue of whether it is effective for a firm to discourage the purchase of its own product in order to support a social cause. The objectives of this study were: a) to examine whether a cause-related self-prevention ad would stimulate more positive evaluations compared to promotional ad, particularly when the product category is more negatively socially accepted; and 2) to determine if a negative attitude toward the product could induce a boomerang effect of a selfprevention ad. Results from three experiments revealed that socially responsible prevention campaigns against firm's own product may be more effective for the product category negatively associated with social concerns or welfare. If products are more limited in the social context, communications of product prevention are beneficial to improve the public image of the brand. However, the self-hurting approach may be inappropriate for potential customers who currently possess a strong negative attitude toward the product.

Purpose Online reviews are critical for sales of online shopping platforms because they provide useful information to consumers. As the eCommerce market grows rapidly, the role of online reviews is becoming more important. The purpose of this study is to analyze how online reviews written by domestic consumers affect product sales by classifying the types of products. Design/methodology/approach This study analyzed how the effects of review characteristics(reviewer reputation, reviewer exposure, review length, time, rating, image, and emotional score) on the usefulness of online reviews differ depending on the product types. Subsequently, how the impact of review attributes (review usefulness, number of reviews, ratings, and emotional scores) on product sales differs according to each product type was compared. Based on the FCB Grid model, the product type was classified into high involvement-rational, high involvement-emotional, low involvement -rational, and low involvement-emotional product types. Findings According to the analysis result, the characteristics of reviews useful to consumers were different for each product type, and the review attributes affecting product sales were also different for each product type. This study confirmed that it revealed that product characteristics are major consideration in evaluating the review usefulness and the factors affecting product sales.
