The Purpose of this study was to investigate the relationship between materialism and clothing buying behavior (clothing shopping orientation, clothing selection standards, use of information sources, store selection standards, purchase and purchase intention of imported clothing). The data were obtained from questionnaires completed by 400 women in the Taegu area whose age was 20 years and older. The SPSS/PC$^{+}$ package was used for data analysis which included a test of reliability, frequency, percentage, factor analysis, t-test, and x$^2$ test. There were significant differences in clothing buying behavior between groups who had a higher tendency and a lower tendency toward materialism. In other words, those who had a higher tendency toward materialism enjoyed their shopping and pursued the world-known brands, imported brands, the latest fashions, and conspicious consumption more than those who had a lower tendency of materialism. The former put a greater focus on the latest fashion styles, brand image, and design then the latter when the\ulcorner bought clothing. Those who had a higher tendency toward materialism utilized more information sources than those who had a lower tendency. The former made purchases from the stores where they stock famous world-known brands and well-advertised stores, and had a greater purchase intention of imported clothing than the latter. In the purchase of imported clothing there was no significant difference between two groups.s.

The purpose of this study lies in giving a help to the rational life of clothing of consumer and presenting some measures for solving problems of the marketing policy of knitwear and the searching of feasibility of the women's knitwear market. The results of this study are as follows; 1. The characteristics of each brand is not clearly introduced to the consumer. This is owing to the lack of the establishment of the policy that emphasize the special feature of each brand. 2. The target of brand almost coincides real consumer, but fashion mood and age group are declined to specific area. So, the scarcity of casual and young age brand is prominent. 3. All brand ought to treat design as the supreme priority other than anything else on the product differentiation strategy dispite the characteristics of the brand. 4. The distribution centered department store is observed very desirable in this study. 5. According to the result of the consmer's behaviors, it has been clarified that display is the most effective sale promotion. 6. Consumer is used to make improvised decision making in the purchasing activities. Thus, it is required to improve consumer's ability of appraisal for quality and material and to establish the calculable, rational consumption pattern.

This research is to restructure the public assessment of housing management in a standardized fashion, and a self-administered questionnaire survey was employed for data collection and analysis. In doing so, all the assessment tools nationwide were identified and assembled to extract the items included in the survey form. The survey form was mailed out to local officers in charge of housing management and professional housing managers in the nation, and the responses were statistically analyzed in order to structure the standard assessment tool of housing management. This research classified 3 main areas (General Maintenance, Operation and Community Living) in evaluating the housing management performance, and identified 35 essential items and 52 optional items. The 35 essential items were drawn from the 16 categories of the 3 areas (11 items of 5 categories for General Maintenance, 7 items of 4 categories for Operation, and 17 items of 7 categories for Community Living), and the rest 52 optional items were from the 16 categories of the 3 areas (24 items of 7 categories for General Maintenance, 26 items of 7 categories for Operation, and 2 items of 2 categories for Community Living). While all the items in the research are quantifiable, it's suggested that qualitative measurements be complementarily utilized in the assessment not only to explore the best practices of housing management but also to refine and modify the standardized tool in response to various environmental changes. As the public assessment of housing management is context-sensitive and critically related to local housing profile, the continuous implementation of the assessment will facilitate shifting the housing paradigm from production and consumption to management and reproduction.

The purpose of this study is to find out an efficient way to utilize clothes. It will be pro- environmental effort besides enhancing clothing life. The study is based on a survey of daily clothing practices. Questionnaire is distributed to female college students who are majoring clothing, textiles, and/or home economics and their parents (n=254). ANOVA, Scheffe test, 1-test and regression are pursued respectively. The main results are as follows: 1. Students, mothers and fathers possess 50.3, 49.9, 45.4 unit clothes, respectively. Mothers possess more formal suits while students possess more casual clothes than the others. The possession pattern is affected by socio-economic variables such as income and purchasing price. 2. In the unused rate of clothes, students'(10.2%) and mothers'(9.7%) rate are significantly higher than that of fathers (6.9%). The unused rate and using efficiency of clothes are affected by socio-economic variables: income and age for unused rate; age and purchasing price for using efficiency. 3. The most important reason for unused clothes is found to be design and color of the clothes. Long years of possessing and change of fashion are the next important reasons. 4. Most of respondents are highly conscious of recycling their clothes. Most of them are willing to donate their clothes to others, re·use or exchange them with the others.

This study focuses on how to improve the use of the sustainable clothing through consignment clothing Stores. This study finds factors for activating consignment clothing stores that can help expand and implement the clothing consumption culture of Korean consumers towards sustainable clothing behavior. The objectives of this study are as follows. First, we identify consumer's sustainable apparel behavior through an in-depth interview with a manager who is currently working in a consignment-selling apparel company in Seoul. Second, we analyze factors for activating a consignment clothing store that help enable the implementation of concrete action plans into Korean culture and towards a sustainable clothing behavior. The study results on consignment clothing stores serve as service factors. First, it increases the participation of consumers in the mindset of secondhand apparel. Second, it secures the quality of used apparel products. Third, it can be seen by expanding the market channel. There is a need to rethink the specialty of apparel products in order to secure the quality of used apparel products and appraisal of experienced apprentices of commodity appraisers.

The purpose of this study is to identify the determinants of the susceptibility of global consumer culture. As determinants, materialism and self monitoring as psychological variables and fashion clothing product knowledge as clothing-related variable were included. It was hypothesized that both psychological variables and clothing-related variable influence susceptibility of global consumer culture. Data were gathered by surveying university students in Seoul metropolitan area, using convenience sampling, and 311 questionnaires were used in the statistical analysis. In analyzing data, exploratory factor analysis using SPSS and confirmatory factor analysis and path analysis using AMOS were conducted. Factor analysis of susceptibility of global consumer culture revealed four dimensions, 'social prestige' factor, 'quality perception' factor, 'conformity to others' factor, and 'conformity to consumption trend' factor. In addition, factor analysis of self monitoring revealed three dimensions, 'center-oriented attention' factor, 'situation-appropriate self-presentation' factor, and 'strategic displays of self-presentation' factor. The results showed that all the fit indices for the variable measures were quite acceptable. In addition, the overall fit of the model suggests that the model fits the data well. Tests of the hypothesized path show that all variables except for the one factor of self monitoring, 'center-oriented attention', and materialism influence all the factors of susceptibility of global consumer culture. The implications of these findings and suggestions for future study are also discussed.

In wireless mesh sensor networks (WMSNs), sensor nodes are connected in the form of a mesh topology and transfer sensor data by multi-hop routing. A data aggregation method for WMSNs is required to minimize the number of routing hops and the energy consumption of each node with limited battery power. This paper presents a shortest path data aggregation method for WMSNs. The proposed method utilizes a simple hash function based on shuffled row major indexing for addressing sensor nodes. This allows sensor data to be aggregated without complex routing tables and calculation for deciding the next hop. The proposed data aggregation algorithms work in a fractal fashion with different mesh sizes. The method repeatedly performs gathering and moves sensor data to sink nodes in higher-level clusters. The proposed method was implemented and simulations were performed to confirm the accuracy of the proposed algorithms.

The purpose of this study is to study the Central Asian costumes($1{\sim}7C$) and develop new design items and suggest new brand launching. Korean apparel industry has been suffering from imbalance of supply and demand caused by the sagging economy and too many apparel companies. Due to the several years of recession, clothing consumption decreased and foreign brand's market share got bigger. As a result, managing a company became difficult and it is time for Korean apparel industry to enter the global market. We need a brand with new image and design that has big potential of purchasing power not only in Korea but also in China, and furthermore in global market. But even nearby Chinese market already became very competitive. One way of approaching Chinese fashion market is to find something special, for example, their historical background. Central Asian culture and costumes, a part of China, has both Eastern and Western culture. No other apparel industry had interest in the Central Asian costumes yet. Therefore, through their costume, a fresh design idea can be suggested.

A hybrid ${\Delta}{\Sigma}$ modulator for audio applications is presented in this paper. The pulse generator for digital-to-analog converter alleviates the requirement of the external clock jitter and calibrates the coefficient variation due to a process shift and temperature changes. The input resistor network in the first integrator offers a gain control function in a dB-linear fashion. Also, careful chopper stabilization implementation using return-to-zero scheme in the first continuous-time integrator minimizes both the influence of flicker noise and inflow noise due to chopping. The chip is implemented in a 0.13 ${\mu}m$ CMOS technology (I/O devices) and occupies an active area of 0.37 $mm^2$. The ${\Delta}{\Sigma}$ modulator achieves a dynamic range (A-weighted) of 97.8 dB and a peak signal-to-noise-plus-distortion ratio of 90.0 dB over an audio bandwidth of 20 kHz with a 4.4 mW power consumption from 3.3 V. Also, the gain of the modulator is controlled from -9.5 dB to 8.5 dB, and the performance of the modulator is maintained up to 5 nsRMS external clock jitter.

As is well known, cooperative sensing can significantly improve the sensing accuracy as compared to local sensing in cognitive radio networks (CRNs). However, a large number of cooperative secondary users (SUs) reporting their local detection results to the fusion center (FC) would cause much overhead, such as sensing delay and energy consumption. In this paper, we propose a fast cooperative sensing scheme, called double threshold fusion (DTF), to reduce the sensing overhead while satisfying a given sensing accuracy requirement. In DTF, FC respectively compares the number of successfully received local decisions and that of failed receptions with two different thresholds to make a final decision in each reporting sub-slot during a sensing process, where cooperative SUs sequentially report their local decisions in a selective fashion to reduce the reporting overhead. By jointly considering sequential detection and selective reporting techniques in DTF, the overhead of cooperative sensing can be significantly reduced. Besides, we study the performance optimization problems with different objectives for DTF and develop three optimum fusion rules accordingly. Simulation results reveal that DTF shows evident performance gains over an existing scheme.
