The purposes of this study were to segment the elderly women's apparel market according to their benefits sought and to develop the profiles of each segment. Questionnaire survey was done to 500 elderly women aged over 55 in Chonbuk province from Mar. 1. to Mar. 15, 2000, and 360 questionnaires were used. Frequencies, percentages, means, factor analysis, cluster analysis, $\chi$$^2$-test, and ANOVA were done with SPSS Win+. Duncan's Multiple Range test was followed. The factors of clothing benefits ere consisted of fashion, brand loyalty, economy, practicality, activity, and utility. The elderly women segmented into 4 groups of the reasonability pursuit, th economy & practicality, the benefit unconscious, and the fashion & brand pursuit. The fashion information sources were divided into mass communication-dominated source and point-of-purchase & consumer-dominated source. The factors of store patronage criteria were divided into product assortment, convenience, and additive service. The economy and practicality pursuit selected their clothing with the help of others, used any kind of information sources less, considered convience of the store more, shopped at traditional market, group size was the biggest, was the oldest, and educated less. The reasonability pursuit selected their clothing by themselves, used all kind of information sources, considered many facets of stores, shopped at department store, was younger, healthier, educated more, and lived with husband more. The benefit unconscious spent less money to their clothing, lower usage of information sources, selected their clothing with the help of others, considered all facets of stores less, shopped at moderate or volume zone apparel market or traditional market, was older, healthy, and involved the widowed more. The fashion and brand pursuit spent more money to clothing, considered the product assortment or additive service of store more, shopped at department store, and selected their clothing by themselves, group size was the smallest, was younger educated more, healthy, and showed a tendency of living with husband.

Consumers are highly interested in processed fishery products that are healthy and superior in terms of convenience, nourishment, and taste. However, current domestic research on processed fishery products is marginal. We systematically analyzed consumer consumption patterns and the relationship to pursuit benefits, selection attributes, satisfaction levels, and reasons for purchase. Consumers considered product information the most important selection attribute, whereas convenience scored highest for pursuit benefits. Furthermore, the influences of selection attributes and pursuit benefits on satisfaction level and the reason for purchasing an item were analyzed using demographic properties as control variables. The variables that affected satisfaction level were residential district (region: B= -0.268, p<0.05.), recipe (B=0.098, p<0.05), nutrients (B=0.124, p<0.05), convenience (B=0.283, p<0.001), and economics (B=0.138, p<0.05). The variables affecting the reason for purchasing were nutrients (B=0.173, p<0.001), convenience (B=0.277, p<0.001) and satisfaction level (B=0.163, p<0.001). Pursuit intention had significant effects on purchase intention; however, selection attributes had no significant effect on purchase intention. Therefore, consumer satisfaction had a significant effect on purchase intention. This result showed that if consumers were satisfied, they intended to repurchase. Attempts to increase repurchases by consumer are needed by fulfilling consumer satisfaction. These data can be utilized as a fundamental reference for sales promotions.

Although the matching Pursuit is effective for video coding at low bit rate, it has a Problem since it needs much more calculation than the conventional block-based video coding method. The proposed fast matching pursuit method reduces inner product calculation that takes the most part of entire calculation by utilizing the symmetry of the absolute values of the one-dimensional Gator dictionary bases, the modified dictionary which allows faster matching without causing image quality degradation, and a Property of the two-dimensional Gabor dictionary that can be grouped in advance to four classes according to its frequency characteristics. Proposed method needs only about 1/8 of multiplications compared to the well-known separability-based fast method proposed by Neff.

This study aimed to analyze the consumption value and clothing pursuit benefits of genderless fashion based on gender identity. The study questionnaire was distributed to and collected from men and women in their 20s and 30s living in Seoul City and the Gyeonggi province. The collected data were analyzed by using Cronbachs α, factor analysis, K-means group classification analysis, and ANOVA. The study results were as follows. First, gender identity was categorized into three groups: the genderless group, the traditional gender rejection group, and the traditional gender acceptance group. Therefore, it is necessary to subdivide gender identity rather than acceptance and rejection of traditional gender roles. Second, an analysis of consumption value based on gender identity showed significant differences in terms of fashion value and expressive value. Therefore, it is important to establish a differentiated strategy based on the relevant gender identity group when establishing genderless fashion design or marketing strategy. Finally, the study results showed that clothing pursuit benefits based on gender identity, there was a significant difference in terms of individuality pursuit, deviation from the norm, and fashion pursuit. In particular, since the genderless phenomenon agrees with the characteristics of the MZ generation, it will be necessary to share brand information or product information through digital media or to utilize a sharing culture-that is, 'meaning out' tendency and 'flex culture' (i.e., conspicuous consumption).

The purposes of this study were to reveal the relation of consumer value variables and to identify the difference of clothing information exploration behaviors on consumer value variables. The data were collected from 267 college women residing in Gwangju using a Questionnaire to general value, clothing value, consumption value and clothing information exploration behaviors. It were analyzed with factor analysis, cluster analysis, T-test, ANOVA and multiple regression analysis using statistical program SPSS 10.0. The results of this research were as follows: 1. Only one factor of general value had a significant influence on 'practical' of clothing value. All of general value and clothing value had a significant influence on the whole consumption value. 2. Clothing information search behaviors was divided into three factors: 'variety pursuit' 'active information collection' and 'uniqueness pursuit'. General value group had a significant difference in 'variety pursuit' and 'active information collection' behavior. Clothing value and consumption value group had a significant difference in all factors of clothing information search behaviors. By implication, this study could be explain each contributions of consumer values and suggest useful variable of consumer values in future clothing behaviors research.

The purpose of this study was to characterize purchase behavior at internet shopping mall and the preference for fashion design through analysis Net generations. The subjects for this sample were teen-agers and university students who had dwelled at pusan and ulsan in south korea. This study had 824 samples who had purchasing of fashion apparels at the internet shopping mall. The sampling data in this survey was analyzed by frequency analysis, factor analysis, T-test, Duncan-test, MANOVA and ANOVA of SPSS WIN package. The results of the study were as follows: 1. It was proved that among 824 individuals, 790(95.9%)individuals uses internet or pc communication and 33 individuals don't use any of them. 35.1% of using internet people have been using that for 1∼2 years. And they used internet for 1∼3 hours in a day(52.9%). And Net generations preferred Internet Shopping Mall because they didn't need to take the troubles of shopping and parking, but at the same time, they seemed to have distrust because they couldn't check the products personally. 2. People who decide to purchase by products and pursuit of information prefer cuffs, collar design, people of pursuit of convenience prefer sleeve, neckline, pants design, people of advertising and pursuit of services prefer cuffs, sleeve, collar, neckline, pants design and color. People who was dependent on perception of danger when they purchase preferred color and pattern. 3. It was proved that purchase attitude for men at internet shopping mall was convenience and for women, advertising and pursuit of services. 1318 teenagers decided to purchase mainly by advertising and pursuit of services at internet shopping mall and semi-adult are less dependent on that factors than 1318 teenagers did. Under high school educational course Net generation was dependent on the factors of advertising and pursuit of services when they purchase at internet shopping mall and above university educational course Net generation decide to purchase by the factors of products and pursuit of information. Also, people whose average income was above 3 million won ware dependent on the factors of advertising and pursuit of services and people whose income was under one million won was decide to purchase by the factors of perception of danger. People whose monthly expenditure on purchase was above 50,000 won ware depend on advertising and pursuit of services more than people whose expenditure was under 50,000 won did.

Doubly-selective (DS) fading channel is often occurred in many orthogonal frequency division multiplexing (OFDM) communication systems, such as high-speed rail communication systems and underwater acoustic (UWA) wireless networks. It is challenging to provide an accurate and fast estimation over the doubly-selective channel, due to the strong Doppler shift. This paper addresses the doubly selective channel estimation problem based on complex exponential basis expansion model (CE-BEM) in OFDM systems from the perspective of distributed compressive sensing (DCS). We propose a novel DCS-based improved sparsity adaptive matching pursuit (DCS-IMSAMP) algorithm. The advantage of the proposed algorithm is that it can exploit the joint channel sparsity information using dynamic threshold, variable step size and tailoring mechanism. Simulation results show that the proposed algorithm achieves 5dB performance gain with faster operation speed, in comparison with traditional DCS-based sparsity adaptive matching pursuit (DCS-SAMP) algorithm.

This study is to analyze and examine the relations of lifestyle, fashion behavior, and make-up behavior of post digital generation and to provide the basic data which help to establish and perform the distinctive marketing strategies targeting the post digital generation. Subjects were 1,460 male and female undergraduates who attend colleges or universities in Seoul, Busan, and Daegu. Average, standard deviation, MANOVA, and ANOVA were conducted using SPSS 12.0 statistic program. The results were as follows: The higher points the group got in all the subfactors regarding information seeking pursuit and sensation intention fascination pursuit, the higher points the group had in the subfactors of fashion behavior and make-up behavior. The group with higher fashionenjoyment pursuit appeared to seek after more brand price choice behavior, internet shopping purchasing behavior, fashion information source seeking behavior, and impulse buying behavior in the subfactors of fashion behavior as well as more self-satisfaction appearance orientation and fashion information buying orientation in the subfactors of make-up behavior. With the group in pursuit of more multi activities, not only were brand price choice behavior and fashion information source seeking behavior in the subfactors of fashion behavior sought after more, but self-satisfaction appearance orientation and fashion information buying orientation in the subfactors of make-up behavior were pursued more as well. The more interpersonal relations the group had, the more self-satisfaction appearance orientation and fashion information buying orientation in the subfactors of make-up behavior as well as the more brand price choice behavior, fashion information source seeking behavior, impulse buying behavior, other-regarding behavior and independent buying behavior in the subfactors of fashion behavior the group had.
