In a competitive and globalized business environment, the need for the green products becomes stronger. To meet these trends, the environmental assessment besides delivery, cost and quality of products should be considered as an important factor in new product development phase. In this paper. a knowledge-based approximate life cycle assessment system (KALCAS) for the collaborative design environment is developed to assess the environmental impacts in context of product concept development. It aims at improving the environmental efficiency of the product using artificial neural networks consisting of high-level product attributes and LCA results. The overall framework of the collaborative environment including KALCAS is proposed. This architecture uses the CO environment to allow users on a wide variety of platforms to access the product data and other related information. It enables us to trade-off the evaluation results between the objectives of the product development including the approximate environmental assessment in the collaborative design environment.

For an outer action $\alpha$ of a finite group G on a factor M, it was proved that H is a, normal subgroup of G if and only if there exists a finite group F and an outer action $\beta$ of F on the crossed product algebra M $\times$$_{\alpha}$ G = (M $\times$$_{\alpha}$ F. We generalize this to infinite group actions. For an outer action $\alpha$ of a discrete group, we obtain a Galois correspondence for crossed product algebras related to normal subgroups. When $\alpha$ satisfies a certain condition, we also obtain a Galois correspondence for fixed point algebras. Furthermore, for a minimal action $\alpha$ of a compact group G and a closed normal subgroup H, we prove $M^{G}$ = ( $M^{H}$)$^{{beta}(G/H)}$for a minimal action $\beta$ of G/H on $M^{H}$.f G/H on $M^{H}$.TEX> H/.

Consumer involvement is one of the most important concepts in target marketing. Marketing managers seeking repeat business and a long term relationship with their consumers must understand the process underlying product evaluation. Therefore, the objective of this study was to find out the relationships between consumer involvement and product performance. Judgement sampling method through survey was utilized to collect the data and the subjects were 614 university students. Factor analysis, reliability test, and regression were used to analyze the data. The research results showed that there were three dimensions of product performance, so called, ‘aesthetic’, ‘utilitarian’, and ‘socio-interactive’. Consumer involvement was positively related to all dimensions of product performance. Understanding of the relationship between consumer involvement and product performance would contribute to build useful marketing strategies.

China is the biggest market for the Korean fashion industry. However, China is still difficult in regards to market entry and market success in China despite the geographical proximity. This study investigated the image of Korea and its impact on brand identity, brand attitude and intention to purchase with a focus on Chinese consumers in order to identify the variables of a country's image that affect a consumer's intention to purchase. The results of this survey targeted 214 Chinese consumers who were used for the final analysis. The survey subjects were female consumers in their 20s and 30s, living in metropolitan cities in China. Exploratory factor, reliability and frequency analyses were conducted using SPSS 19.0; in addition, confirmatory factor and path analyses were administered with AMOS 18.0. We identified two general images of Korea (economy and culture), two images of Korean (stylish and friendly) and three Korean fashion-product related images (quality, design and prestige). The results of the structural equation model were as follows. 1) Economy factor exerted significant effect on quality and prestige. 2) Stylish factor exerted a significant effect on all of the Korean fashion product images (quality, design and prestige). Friendly factor exerted positive impact on prestige. 3) All of the Korean fashion product images significantly influenced brand identity. 4) Brand identity exerted a significant effect on brand attitude. Lastly, brand attitude significantly affected intention to purchase.

This study introduced the components of apparel store, which include product and service factor to reflect the modified conception of service. The purposes of this study were to investigate the dimensions of the components of apparel store and to examine consumers' rating of importance on the components of apparel store. In addition, this study explored the effect of clothing involvement and demographic variables on importance perception. Data were collected via a questionnaire from young adult females in their twenties. The results of this study revealed five dimensions of service factor: environmental service, salesperson service, attitude and policy service related to exchange and refund, policy service related to promotion, and policy service related to convenience. Factors related to product were identified price, quality, variety, fashion, design and brand. Attitude and policy service related to exchange and refund is the most important factor that consumer perceived. Salesperson service and product quality were the second important factors. The relatively important factor in each service dimension was this : display in the environmental service, the ability of salesperson to resolve customer's complaints in the salesperson service, sales person’s courtesy in managing exchange or refund in policy service. Clothing involvement and demographic variables do affect consumers’perception on importance.

SCM activities in a company are considered as total innovation through synchronizing supply and demand while maintaining appropriate inventory level and reducing the business operating costs. Until now, even several researches are carried out on the SCM performance of the companies which have introduced and been operating SCM, the research on the cost analysis for the inventory which occurs frequently on supply chain is still insufficient. Especially, for the electronics industry in which the product depreciation is sharp caused by the short product life cycle and the complexity of distribution channels, even the inventory related costs are a major factor in business management, since the current estimated criteria of inventory costs are limited to the interest and maintenance management costs, the criteria do not reflect the total influence of the product depreciation and lost opportunity cost which are related to the business management. Furthermore, even though the rapid price drops of the distributor inventory caused by the frequent new model launch can be covered by the product manufacturers, the scale of total costs related to the inventory has not been conceived because the price compensation is traditionally considered as a market costs. In this research, we analyzed the inventory characteristics of electronics industry in which the price depreciation happens frequently, newly defining the estimated criteria of the product total inventory cost which includes price depreciation from the product manufacturers' view. Finally we focus on the case study of a representative electronics company and verify the scale of the influence on management performance.

Purpose: This study is a quantitative study and analyzes the effect of evaluating the extreme and usefulness of product reviews on sales performance by using text mining techniques based on product review big data. We investigate whether the perceived helpfulness of product reviews serves as a mediating factor in the impact of product review extremity on sales performance. Research design, data and methodology: The analysis emphasizes customer interaction factors associated with both product review helpfulness and sales performance. Out of the 8.26 million Amazon product reviews in the book category collected by He & McAuley (2016), text mining using natural language processing methodology was performed on 300,000 product reviews, and the hypothesis was verified through hierarchical regression analysis. Results: The extremity of product reviews exhibited a negative impact on the evaluation of helpfulness. And the helpfulness played a mediating role between the extremity of product reviews and sales performance. Conclusion: Increased inclusion of extreme content in the product review's text correlates with a diminished evaluation of helpfulness. The evaluation of helpfulness exerts a negative mediating effect on sales performance. This study offers empirical insights for digital market distributors and sellers, contributing to the research field related to product reviews based on review ratings.

In this study, in order to achieve the before-mentioned study purpose, the importance of developing the new product, the relationship with the design, and the design element for developing the new product were considered. In order to extract the importance of the design element which is applied to the development of the new product design, the research model about the induction of the priority was created, the evaluation items were instituted, and the demonstrative research approach was performed in order to recognize the relationship among those elements. Firstly, in the process of selecting the items for the application, 14 evaluation elements which were extracted through the advanced study data were grouped in 4 kinds of dimensions, and the properties which are related with the Digital TV product were composed up of 36 items. Through the factor analysis, by decreasing the detailed standard for the evaluation of 36 items, the parsimony was secured, and the characteristics which the various items contain induced into one factor. Secondly, the detailed factors which were united into one factor went under the paired comparison as one by one through AHP again, and then the importance degree was generated. First of all, as the first stage of AHP, the decision making factors which affect the whole achievement of purpose of the decision making were classified as in a hierarchical style. From these research results, it was known that the functional factor and esthetic factor in the process of designing the new product are the major affecting variables, and it was confirmed that in case of the Digital TV products group, the factors such as the high quality of picture, big screen, user interface, sound, product reliability, style, size, indoor reproduction, and guarantee are the main factors which influence the need of the consumers in purchasing products.

Purpose - This paper aims to identify and rank factors that influence impulse buying behavior among shoppers in Dubai. Research design, data, and methodology - Questionnaires were collected from 168 Dubai shoppers using non-probability quota sampling. Factor Analysis was completed to identify factors triggering impulse buying traits. Results - Six antecedent factors were identified: hedonism, in-store influences, product related influences, socialization, promotional activities, and convenience. Surprisingly, product related influences were the most significant in stimulating impulse buying behavior. Conclusions - This research suggests that a multitude of factors affect shopper propensity for impulse buying, with non-economic factors like product and in-store related influences having a significant impact. Hence, retail managers should concentrate on these in merchandising and promotional efforts. Against the backdrop of Dubai, one of the biggest retail destinations, this study contributes to present knowledge on impulse buying behavior. In terms of shopper inclinations and likeliness to purchase products, it highlights how shoppers respond to special in-store displays and discount offerings. For marketers, the findings regarding relative significance of various factors may help in strategies to attract consumers.
