The 'Quality Competitiveness Index' (QCI) is defined as an quantitative and disinterested indicator that measures and compares the quality of products across the world. The purpose of this study is to suggest the 'Quality Competitiveness Assessment Model' (QCAM) and calculate QCI of a popular UHF RFID Label tag (Global ISO 18000-3C supported) available these days in a global apparel market. The model was based on KS-QEI(Korean Standard-Quality Excellence Index), and was composed with the following 4 evaluation categories, a process capability test, an environmental reliability test, a durability test and a design margin test. The QCI score can be calculated with the following formula, using the weighted arithmetic mean between a score of each evaluation category ($X_1$, $X_2$, $X_3$, $X_4$) and each weight($w_1$, $w_2$, $w_3$, $w_4$). The actual weights was determined by an result of AHP survey to which was conducted for the related Industry-University-Institute experts. The proposed index shows the results of comparisons with global competitor's products as well as the high-quality domestic RFID label tags. In addition, it will play an important role for manufacturers when developing their future products.

The purpose of this study was to apply a scientific and systematic method for assessing fashion goods' TV ads effects by EEG and questionnaires as determined by the type of ads appeal. Ads stimulants used in the survey were limited to underwear and sportswear that were advertised during $2000{\sim}2002$ on TV: 4 information-transferring and 4 emotion-evoking ads were used. Subjects were thirty healthy male and female college students. EEG was extracted from six lobes and the recorded EEG was analyzed by the range of frequency of ${\theta},\;{\alpha}\;and\;{\beta}$ waves. Data were analyzed by SPSS 11.0 with reliability test, $x^2$-analysis, t-test and frequency analysis. The emotion-evoking ads showed higher scores in memory, recall and attitude towards the ads. The responses of ${\theta}\;and\;{\alpha}$ wave were active throughout the ads but the response of ${\beta}$ wave was not. The results by the survey and the EEG test showed high similarities, indicating the EEG tests could be used as the supplementary tool for measuring ads effects.

폴리프로필렌(PP)은 고결정성 범용수지로서 염색성, 내열성, 촉감 등의 문제로 의류용 소재로는 부적합하여 초기에는 카펫용 섬유로서 가염형 폴리프로필렌 섬유가 상업화 되었지만 성공하지는 못하였다. 그 후, 섬유 산업도 의류용 외의 산업자재, 생활 자재 분야 등이 성장함에 따라, 폴리프로필렌 섬유의 수요가 확대되었다. 최근들어 스포츠 액티브 의류가 일반의류 트렌드로 들어오면서 기능성 섬유가 요구되고 이 분위기에 맞춰 다시 한번 폴리프로필렌 섬유의 의류화가 요구되는 시점이 되었으며 섬유중 에너지 소비량이 가장 적고, 쉽게 재용해할 수 있으며 소각시 유해 가스발생량이 매우 적은 특징등이 있기 때문에 지구 환경보호의 입장에서 폴리프로필렌 섬유가 재검토되고 있다. 이번 실험은 분산염료를 이용하여 농도별, 온도별, 시간별, 후처리시 시간과 온도의 변화로 가염 PP/PET 섬유의 염색특성을 알아보기 위해 실험 진행하였다. 실험에 사용되는 시약은 1급으로, $CH_3COOH$, NaOH, $Na_2S_2O_4$이며, 조제는 분산제, 정련제를 사용하였다. 먼저 온도별 실험에서 $40^{\circ}C$에서 승온하여 각각 $100^{\circ}C$, $110^{\circ}C$, $120^{\circ}C$, $130^{\circ}C$에서 온도에 따라 염색되는 정도를 알아보았다. 가장 높은 흡진을 보이는 온도에서 각각 40min, 50min, 60min, 70min 염색 유지시간 실험을 하여 염색이 안정되는 시간을 측정하였다. 위의 실험 결과 최적의 조건으로 염색농도에 따른 Build up 실험을 진행하였다. 가염 PP/PET 섬유는 일반 Polyester처럼 $120{\sim}130^{\circ}C$에서 가장 높은 염색농도 값(K/S)을 보인다. 또한 $130^{\circ}C$에서의 유지시간에서는 50 min 이상 진행시 더 이상의 흡진이 없거나, 염료의 탈락이 있음을 알수 있다. Build up 실험에서는 8.0%까지 실험하였지만, 결과는 그 이상농도를 사용하여도 염색은 가능함을 알 수 있었다. 후처리에 대한 실험에서 염료에 따라 차이가 있지만 크게 영향을 받지 않는 것으로 보이며, 제품성 평가 결과를 보면 후처리를 했을 경우 견뢰도가 우수한 것을 알 수 있었다.

As SPA brands are growing in Korean apparel markets, they are extending their well-established brands into new markets (i.e., SPA brand extensions). To investigate psychological mechanism underlying SPA brand extensions, this study conceptually proposed such consumer information processing of SPA brand extensions as (1) perception of similarity between SPA brand extensions and their original brands and (2) evaluations on the SPA brand extensions (i.e., attitude and purchase intent). For hypothetical SPA brand extensions (high, moderate and low similarity conditions), perceived similarity was measured by using a eye-tracker and evaluations were assessed by using a self-reported questionnaire. The results reveal that the amount of external information searching for SPA brand extensions was larger in the following order: moderate, low and high similarity conditions. The depth of SPA brand information processing was also deeper in the same order. Evaluations on SPA brand extensions were higher in high and moderate similarity conditions than in low similarity condition. The findings suggest that the evaluations are affected by perceived similarity and the amount of cognitive efforts in processing SPA brand extensions.

Recently, due to the increase of online reviews and the development of analysis technology, the interest and demand for online review analysis continues to increase. However, previous studies have not considered the emotions contained in each vocabulary may differ from one reviewer to another. Therefore, this study first classifies the customer group according to the customer's grade, and presents the result of analyzing the difference by performing review analysis for each customer group. We found that the price factor had a significant influence on the evaluation of products for customers with high ratings. On the contrary, in the case of low-grade customers, the degree of correspondence between the contents introduced in the mall and the actual product significantly influenced the evaluation of the product. We expect that the proposed methodology can be effectively used to establish differentiated marketing strategies by identifying factors that affect product evaluation by customer group.

The fashion apparel industries have demanded to be extremely consumer-oriented. Therefore, the need of personalization arises. The purpose of this study is to investigate the relationship between apparel shopping orientation and various personalization strategies provided in the apparel shopping process. A total of 422 questionnaires were used for statistical analysis. Canonical correlation and ANOVA were conducted. Results indicated that higher level of demand for "sale-promotion personalization" and "personalized customer relationship" were significantly related to high level of fashion innovativeness and price consciousness. Consumers who seek for high level of "personalized advice" and "personalized fit" were likely to be price conscious and conforming to clothing but not innovative in terms of fashion and clothing. Shopping orientation group differences were also reported in the study. In personalizing of apparel products, distinctive but relevant strategies should be implemented according to the need of the consumers.
