The kinematically admissible velocity field is developed for the analysis of the curving of an eccentric extrusion. The curving of product in extrusion is caused by the difference of the linearly distributed longitudinal velocity on the cross-section of the workpiece at the dies exit. The result of the analysis show that the curvature of product increases with the increase in eccentricity of gravity center of the cross-section of the workpiece at the die entrance from that of the cross-section at the die exit. It also increase with the die land dimension. By the DEFORMTM-3D analysis, the curving of T-shaped product in extrusion is changed by the eccentricity, die land length and the friction constant. The result of the analysis by DEFORMTM-3D software shows that the curvature of circular shaped product increases with the eccentricity. The two analysis and one experiment show the curving phenomenon in eccentric extrusion process.

기업이 다른 어떤 방법으로 이미지를 쇄신한다고 하더라도 실질적인 제품의 정책과 조화를 이루는 제품의 색채 계획이 이루어지지 않는다면 그 상품은 신뢰를 얻을 수 없다. 즉, 제품의 색채는 제품의 기능과 용도, 형태, 재질 등의 제품의 특성에 종합적으로 관련되는 것으로서 제품의 중요한 품질로 여겨지기 때문이다. 많은 기업에서는 유행하는 색채나 미래의 소비 심리를 예측하기 위한 노력을 기울이고 있다. 그들의 노력을 따라가기 위해서는 기업들이 색채의 인프라를 구축하고 사회의 현상을 읽어낼 수 있는 능력을 키우며, 연령별, 소득별 등에 따른 소비자의 생활양식을 이해해야 한다. 본 연구에서는 젊은 세대들의 제품의 색채 선호 경향을 성별로 알아보고, 제품의 색채가 제품이미지와 제품태도에 미치는 영향에 대해서 실증적으로 분석하였다. 실험을 통하여 얻은 연구 자료는 SPSS/Win 12.0을 이용하여 빈도분석, 교차분석, T-test, One-Way ANOVA분석을 실시하였다. 본 연구에서 나타난 결과를 살펴보면, 제품의 색채에 따라 색채선호도, 제품이미지, 제품태도가 달라진다는 결론을 얻게 되었으며, 이러한 결과는 제품의 기능가치에 부가적인 감성가치를 형성하는 중요한 요소가 제품의 색채라는 점과, 특히 색채가 차지하는 비중이 큰 제품인 경우 소비자에게 미치는 영향을 사전에 조사하여, 소비자의 반응이 어떻게 달라지는지를 미리 점검하고 제품의 색채를 결정하는 것도 매우 중요하다는 시사점을 제시한다.

In this paper, we want to verify some properties in tensor product. It is interesting to think semi-exact sequence in tensor Product by [3]. Moreover no hardness is there in process and we want to discuss the commutativity in tensor product. For a certain semi-exact sequence, if we product arbitrary Abelian group for each group then the tensor Product will do or not. Here, we have positive answer. At first we define the semi-exact sequence as following.

In this study, a novel and flexible recommender system was developed, based on product taxonomy and usage patterns of users. The proposed system consists of the following four steps : (i) estimation of the product-preference matrix, (ii) construction of the product-preference matrix, (iii) estimation of the popularity and similarity levels for sought-after products, and (iv) recommendation of a products for the user. The product-preference matrix for each user is estimated through a linear combination of clicks, basket placements, and purchase statuses. Then the preference matrix of a particular genre is constructed by computing the ratios of the number of clicks, basket placements, and purchases of a product with respect to the total. The popularity and similarity levels of a user's clicked product are estimated with an entropy index. Based on this information, collaborative and content-based filtering is used to recommend a product to the user. To assess the effectiveness of the proposed approach, an empirical study was conducted by constructing an experimental e-commerce site. Our results clearly showed that the proposed hybrid method is superior to conventional methods.

This paper examines critical successful elements related to the management of new product development process. For this, we have selected a VK-X100, slim bar type cellular phone, produced by VK mobile co., which was thought as a successful product development case and then analysed the case from a concept driven strategic product development's point of view. We have performed in-depth interviews with project managers, engineers and designers to get information on the product development process and analysed huge amount of data obtained from web-sites, global market indicators, and related firms' materials to find a changing trend of market conditions. The findings suggest that the successful new Product development and management is shaped by a number of different factors, such as the business environments, firm's technological level, firm's deep market insight capabilities, nature of the product development activities, and so on. Finally, we suggested the limitation of our research and further research subjects that would be required to support our findings.

As apparel manufacturers have increased their outsourcing garment making to cope with the rapid changing market, the information sharing has been the most important factor for the Korean apparel industry. The purpose of this research was to study the present state and the needs of the information sharing between the apparel manufacturers and the contractors; and the relationship between the product property (basic/fashion product) and the information sharing property. A total of 86 Korean apparel manufacturers were surveyed for the study. The results are: 1) the information sharing level on manufacturing capacity, manufacturing processing condition, and product quality were a bit higher than other surveyed information, but the level on inventories and sales were lower than others. in addition, the information sharing needs by online system of manufacturing capacity, manufacturing processing condition, and product quality were greater than other information; 2) In the case of fashion product, the information sharing needs of product quality by online system were much greater than in the case of basic product. This study is expected to help apparel manufacturers to construct their information sharing system which is apt for their product property and needs.

This study tested the validity of a three-factor model of the centrality of visual product aesthetics developed by Bloch, Brunel, and Arnold (2003) and explored the relationships between the centrality of visual product aesthetics and the relevant constructs. It was hypothesized that the path relationships including innovativeness and consumer independent judgment making are relevant constructs of the centrality of visual product aesthetics. Data were gathered by surveying university students in the Seoul metropolitan area (using convenience sampling) and 322 questionnaires were used in the statistical analysis. Correlation analysis, factor analysis, and regression analysis were conducted to analyze the data. The findings show the validity of the three factors (value, acumen, and response intensity) of the centrality of visual product aesthetics. Tests of the hypothesized path show that innovativeness influences the centrality of visual product aesthetics both directly and indirectly through consumer independent judgment making. Innovativeness positively influenced consumer independent judgment making and the three factors of the centrality of visual product aesthetics, whereas consumer independent judgment negatively influences the response intensity factor of the centrality of visual product aesthetics. The implications of these findings and suggestions for future study are also discussed.

Various products are displayed and traded in superstores. Therefore, providing the information of these diverse products plays a crucial part in acknowledging their presence. Currently, superstores mostly utilize printed materials to provide product information and promotion of displayed products. A display equipment is utilized for providing product information and promotion of certain high-end and new products. As such, utilizing an expensive display equipment in order to provide product information fragmentarily for 1 product or successively can be referred to as being inefficient. This paper aims at proposing a method that enables the description of product information efficiently by utilizing a display specific for store support in order to overcome the restriction mentioned above. A test was executed in order to verify the potential of the method of providing product information though the proposed display.

We developed Intelligent Product Search Agent based on SWRL, and this agent can search product information with knowledge(facts and rules) on the web, implement price comparison for searched products considering delivery rates. Existing keyword based product search engines is poor at searching intent products though a user has already prefect knowledge about intent produces. Furthermore if a user has insufficient knowledge, it is impossible to implement search. Also, existing price comparison shopping mall gives users comparison service considering total price(product prices, taxes, delivery rates), this service is valid to single product and has limitations of system expansion and up-dating because of not rule base but programming base. If there is appropriate knowledge on the Semantic web and this makes product information retrieval possible, above problems can be solved clearly. In this research, we developed Intelligent Product Search Agent based on SWRL that can search product information efficiently by making agent to handle facts and rules by itself.
