The purpose of this was to classify consumer groups according to the life styles and analyze buying intention and evaluation criteria of apparel product, opinion to 4p\`s aspect among consumer groups. And it was to clarify relationships between the experience of CATV home shopping and buying intention and evaluation criteria of apparel product, opinion to 4p\`s aspect. The subjects of this study were 270 women living in Chonbuk and Chonnam regardless their experience in CATV home shopping. For data analysis, frequency, percentage, mean, t-test, factor analysis were conducted. The results were as follows; First, the type of life style were classified into the following subdivisions: products confirmed type, price-quality regarded type, time regarded type, new product regarded type. Second, the significant differences among the classified life style groups were found in buying intention, evaluation criteria of apparel product, and opinion to 4p\`s aspect. Third, there were significant differences in buying intention, evaluation criteria of apparel product, and opinion to 4p\`s aspect according to TV home shopping experience.

Tensor product immersions of a given Riemannian manifold was initiated by B.-Y. Chen. In the present article we study the tensor product surfaces of two Euclidean plane curves. We show that a tensor product surface M of a plane circle $c_1$ centered at origin with an Euclidean planar curve $c_2$ has harmonic Gauss map if and only if M is a part of a plane. Further, we give necessary and sufficient conditions for a tensor product surface M of a plane circle $c_1$ centered at origin with an Euclidean planar curve $c_2$ to have pointwise 1-type Gauss map.

Purpose - Recently, many theoretical researches suggested that arts-based marketing strategies provide many benefits for marketers to differentiate their brand or product from others. However, there has been little research focusing on consumers' response types from artwork (artifact-emotion appraisal; A-emotion vs. represented world-emotion appraisal; R-emotion). In order to deepen our understanding of arts-based marketing strategies, we addressed a research question related to how artwork-provoked consumers' emotional response can impact the perceived evaluation of art infused products. Research design, data, and methodology - To answer the research question, we conducted a pretest and one experimental study. The experimental study was 2(art-provoked response type: A-emotion vs. R-emotion) by 2(emotional valence: positive vs. negative) by 2(produce type: hedonic vs. utilitarian) mixed design. The art-provoked response type and emotional valence were between-subject design and product type was within subject design. For the experimental study, 108 undergraduate students and graduate students were randomly assigned to one of 4 conditions (A-emotion-positive, A-emotion-negative, R-emotion-positive, R-emotion-negative). Participants reported their evaluation of art-infused product and other items for a manipulation check. Results - The major results from the experimental study are as follow. First, participant's art-provoked response type influenced evaluation of art infused products differently. More specifically, the effect of emotional valence of artwork on product evaluation was not significant in A-emotion. However, in R-emotion, relative to the product with artwork provoked negative emotional valence, the product with artwork provoked positive emotional valence elicited significantly higher product evaluation. Second, product type also affected the art infusion effect significantly. Particularly, the differential effect of participant's art-provoked response type on product evaluation revealed when it is for a utilitarian product, but not for a hedonic product. Conclusions - Theoretically, the findings of this study expand academic research on art infusion. And the findings also can be extrapolated to generate lots of implication for marketers. In sum, when they plan art marketing strategies to build the favorable relationship with their customers, they need to consider customers' response type of an infused art and product type.

본 연구는 온라인 사용후기 방향성이 정보 신뢰성과 제품태도에 미치는 영향을 분석하고 소비자의 온라인 쇼핑경험과 제품유형의 조절효과를 규명하는데 그 목적이 있다. 온라인 사용후기를 제품의 장점만을 언급하는 일면 메시지와 장단점을 함께 언급하는 양면 메시지로 분류하고, 제품유형을 기능재와 쾌락재로 분류하여 실험물을 제작하였다. 또한 소비자의 온라인 쇼핑경험이 많은 집단과 적은 집단으로 구분하여 가설 검증에 사용하였다. 연구결과, 온라인 사용후기 방향성은 정보 신뢰성과 제품태도에 모두 유의한 영향을 미치는 것으로 나타났으며, 쇼핑경험의 조절효과는 정보 신뢰성과 제품태도에 모두 유의한 것으로 조사되었다. 온라인 사용후기가 정보 신뢰성에 미치는 영향에서 제품유형의 조절효과는 유의한 것으로 나타났으나, 제품태도에는 유의한 조절역할을 하지 않은 것으로 나타났다. 그리고 본 연구의 결론에서는 연구결과에 따른 시사점과 한계점을 논의하고, 향후 연구방향을 제시하였다.

This paper discusses an optimization-based approach for the design of a product platform for industrial three-axis linear-type robots, which are widely used for handling objects in manufacturing lines. Since the operational specifications of these robots, such as operation speed, working distance and orientation, weight and shape of loads, etc., will vary for different applications, robotic system vendors must provide various types of robots efficiently and effectively to meet a range of market needs. A promising step toward this goal is the concept of a product platform, in which several key elements are commonly used across a series of products, which can then be customized for individual requirements. However the design of a product platform is more complicated than that of each product, due to the need to optimize the design across many products. This paper proposes an optimization-based fundamental framework toward the design of a product platform for industrial three-axis linear-type robots; this framework allows the solution of a complicated design problem and builds an optimal design method of fundamental features of robot frames that are commonly used for a wide range of robots. In this formulation, some key performance metrics of the robot are estimated by a reducedorder model which is configured with beam theory. A multi-objective optimization problem is formulated to represent the trade-offs among key design parameters using a weighted-sum form for a single product. This formulation is integrated into a mini-max type optimization problem across a series of robots as an optimal design formulation for the product platform. Some case studies of optimal platform design for industrial three-axis linear-type robots are presented to demonstrate the applications of a genetic algorithm to such mathematical models.

본 연구는 기업의 공익연계마케팅 활동의 효과를 측정하기 위해 소비자의 공익연계마케팅 제품에 대한 선호도를 종속변수로 선정하여 실험을 진행하였다. 공익연계마케팅 제품에 대한 선호도에 영향을 미치는 주된 요인 중 하나인 제품 유형의 영향에 초점을 두었다. 기존 연구는 제품 유형이 공익연계마케팅의 효과에 미치는 영향에 관해 쾌락적인 제품이 실용적인 제품에 비해 공익연계마케팅의 효과가 높다고 밝혔고, 이는 죄책감의 논리로 주로 설명되었다. 그러나 상반된 연구 결과가 존재하고 죄책감의 수준은 소비자나 시장 환경의 특성에 따라 다를 수 있다는 점에서, 본 연구는 제품 유형의 영향을 심층적으로 살펴보고자 하였다. 그래서 한국과 중국 시장을 비교 대상으로 하여 국가와 제품 유형 간의 상호작용 효과를 검증하였다. 검증 결과, 유의한 효과가 존재하였고 한국과 중국 소비자 간에 제품 유형에 따른 공익연계마케팅 제품 선호도에 대한 차이가 있었다. 이와 같은 연구 결과를 바탕으로 본 연구의 시사점과 한계점 및 향후 연구방향에 대해 제시하였다.
