The purpose of this study was to find differences in evaluation criteria and product information based on jeans products consumers. The participants of this study were women age of 19 to 30 years. This study was implemented by descriptive survey method using questionnaires. A total 182 questionnaires were analyzed in this study. The subjects were grouped by the evaluation criteria of purchasing jeans through an online shopping. Finding of the study showed that, Group 1 was high involvement group. They conscious of both style feature and practicability of jeans when they bought jeans. Group 2 was low involvement group. They are not conscious of those features. The important factors were different by groups. The most important factors of purchasing jeans for Group 1 were fashion trend and practicality. Price was the most important factor for Group 2. They bought jeans at extremely low or high price. On the other hand, Group 1 bought jeans of diverse prices range. The popular shopping sites were different between two groups. The department store was the most important place purchasing jeans for both groups. The second important place was specialty stores for Group 1, and online shopping for Group 2. The usefulness of product informations were also examined when they evaluated the jeans at online shopping. The most useful product informations were leg cut style and rise length. Fit information was very important for Group 1. Group 1 considered that the function of zoomming the picture image was important. The material characteristic and name of brand were also useful than Group 2. But the size and care instruction were not highly useful.

Traditionally, the target of manufaturing technology strategy was derived in a efficiency, cost and productivity. So most activities of the manufacturing brought focus into the engineering technology, equipments and research and improvement of new products to maximize the efficiency. As a resell of this legacy, most of the activities of manufacturing has been executed on the method of quality improvement, development of new equipment to incense the efficiency and the research of materials for new products. Those trends, however overlook the operation management activities which is very important as a assets in competitive strategy. But the market enviornment of morden manufacturing companies faced to the uncertainty and complexity. So they need capability of competition which requires new concept of manufacturing technology strategy to grasp the competitive advantages. In this point of view, this paper deal with the empirical study in korean manufacturing technology strategy of the electic and electronic industry. For the empirical study, check list was made to survey the 98 manufacturing companies. The analysis procedures are as below. First, identify the manufacturing technology group an product structure group by each variable. Second manufacturing technology variables are segmented into product technology and vertical integration, suborder and infrastructure, to analyse the decision making pattern which derive the strategy groups. Third, by the fitness analysis between product structure group and manufacturing technology group, the economic results of a growth rate of sale and a profit rate of sale are tested. In this approach, fitness analysis between product structure group and manufacturing technology group show, as a whole, the no significant values in economic results of the company. But investigating the statistical values shows the trend that econmic result of the complany is somewhat higher when the degree of fitness of manufacturing technology strategy by product structure has high value. Concluding the remarks, the competitive advantages of company lies not in the efficiency of manufacturing systems but in the way of the structure and decision making pattern of the manufacturing system. And the cons i stoney between strategy target and manufacturing technology strategy, and the consistency of manufacturing technology strategy and product structure are the term of competitive advantages.

This experiment was conducted to determine the optimum level of green tea by-product (GTB) in diets without antibiotics and to evaluate its effect on broiler performances. A total of 140 Ross broilers were kept in battery cages for a period of 6 weeks. Dietary treatments used in this experiment were antibiotic free group (basal diet as a control), antibiotic added group (basal+0.05% chlortetracycline), GTB 0.5% (basal+GTB 0.5%), GTB 1% (basal+GTB 1%) and GTB 2% (basal+GTB 2%). Antibiotic added group showed significantly higher body weight gain than other treatments (p<0.05). However, no significant differences were observed in feed intake and feed efficiency among treatments (p>0.05). The addition of green tea by-product to diets tended to decrease blood LDL cholesterol content compared to control group although there were no significant differences among treatments (p>0.05). Addition of green tea by-product increased docosahexaenoic acid (DHA) in blood plasma and tended to decrease cholesterol content in chicken meat, but a significant difference was not observed (p>0.05). The values of TBA in chicken meat decreased in groups fed diets with green tea-by product and antibiotics compared to control group (p<0.05). The crude protein content in chicken meat was decreased slightly in treatments with green tea by-product and antibiotics supplementation. The abdominal fat was increased in chickens fed with diets with green tea by-product compared to the control (p<0.05).

The purpose of this study is to examine the semantic structure about the image shown on the product, brand and advertisement and figuring out its features through the correlation among brand images. For the study, nine brands(Guess, Bangbang, ONG, NIX, TBJ, Levi's, OPT, FRJ, Jambangee) as subjects for investigation has been selected and divided into the image of brand(9 brands), product(108 products, 12 pieces for each product) and advertisement(9 points) by the measure of 26 adjective pairs. The survey has been collected on the subject of 540 men and women who live in around Busan city areas and has been taken the statistics. The results on investigating the semantic structures of the product images about jean brands, there are five main factors, such as, individuality, attractiveness, activeness, modernity, hardness & softness. The results on examining the semantic structures of the brand images about jean brands, the factors are attractiveness, activeness, vitality, hardness & softness, fadness. The results on investigating the semantic structure of the advertisement images about jean brands, the factors are attractiveness, individuality, modernity, activeness. The results on the classification of brand images are presented as four groups, the first group is that brand and advertisement image are pretty similar but product image is differential according to brand and the second group, product and advertisement image are similar but brand image is differential. The third group is that product and brand image are similar but advertisement is differential and the fourth group, product, brand and advertisement are similar.

By developing attitude transfer model, this study examined the co-marketing alliance effect between fashion and other industries (i.e., service and product brands) based upon the information integration theory. In addition, it examined the product tangibility/intangibility effects of partner brands by controlling stimuli: two alliance cases of fashion and service brands and two alliance cases of fashion and product brands. A total of 1,037 Korean women aged 20 to 39 were surveyed to compare the prior- and post- attitudes toward fashion/partner brands under four fictitious co-marketing alliance cases. Confirmatory factor analysis (CFA), multi-group CFA, structural equation modeling (SEM) analysis, and multi-group SEM analysis were conducted to test the hypotheses. The results demonstrated that the prior-attitude toward fashion brand partially affected the alliance attitude, and the co-marketing alliance was affected by prior-attitudes partner brands. The result of multi-group SEM analysis supported the significant differences between service and product brands as alliance partners, which might refer to the effect of product tangibility, existing in brand alliance contexts. The alliance evaluation affected the subsequent evaluations on each participating brands. This study empirically provides the conceptual structure of how consumer attitudes toward the participating brands interact with the attitudes toward alliance and offer practical insights. Specifically, upon employing the manipulated co-marketing alliances cases, this study demonstrates the partnering effect according to product tangibility of partner brands.
