The purpose of this study is concerned with suggesting a new a, pp.oach to evaluating the overall product quality in the sense of the relative efficiency of products, whose quality is measured with 8-dimensional attributes, suggested by Garvin. The attributes included 8 quality measures, that is, performance, features, reliability, conformance, durability, serviceabilit, aesthetics, and perceived quality. This study, also, introduced DEA(Data Envelopment Analysis) as an evaluation tool to tackle the problem of how to measure one product against another when each product can be measured along a number of dimensions, and given that there exists no a priori satisfactory weighting scheme to combine these dimensions into an overall rating for each products. In order to a, pp.y the DEA to evaluating the products, we must define two concepts, such as DMU(Decision Making Units) and input-output relationship. Finally, the suggested method in this study was validated through a case study of the electric jar, and this DEA a, pp.oach can be used in evaluating the other products with multi-attrribute quality.

The purpose of this study was to examine consumers' product experiences from the time when the consumer purchases a smart phone, through to the period of use, and to evaluate the product after a period of usage by comparing two groups of smart phone users of the two leading brands, Galaxy S and iPhone 4G. Product experiences were considered through the process of a consumer purchasing and using a product throughout the whole cycle of product consumption. Product experiences were compared between the two brand users according to their demographic backgrounds. The results indicated that iPhone 4G users were more likely to experience functional superiorities and emotional varieties than Galaxy S users. Especially, iPhone 4G users were more likely to experience enjoyment, aesthetics, enhanced self-images and good relationships with others through the smart phone than the Galaxy S users. Galaxy S users were more likely to identify a corporate's image as a superior feature, while iPhone 4G users were more likely to identify multi-functions and endless applications. This study implies that not only the product's functional superiorities but also the consumers' entire cycle of product experiences should be carefully examined and reflected in the development of successful new products in this competitive market.

For every country, the flag is a major symbol that represents the country. Establishing image though the use of the country's symbol is more important for achieving national competitiveness in this global age. In Korea, Taekuki has not been actively applied to fashion products, however Korean people began to realize the Taekuki as a motif of fashion with 2002 World Cup. Thus, research on fashion product development applying Taekuki is needed. This research developed designs for fashion product development applying Taekuki. In addition, through suggesting various applied motives, this research explored the product possibility of global fashion design that represents Korean identity and fashion. For research method, after research on fashion design process, design development was progressed according to the 4-phases that comprehends processes previous researchers presented. First, in the problem recognition phase, background on the introduction of Taekuki to products and Taekuki fashion during 2002 World Cup was analyzed. Then, the need and possibility of fashion product development applying Taekuki's formative characteristics were found. Second, in research and analysis phase, meaning and history of Taekuki as well as flag fashion product developments in the U.S. and England examples were reviewed. Also, individual interviews with experts and consumers were conducted to collect qualitative data regarding product and design direction. Third, in idealization for problem solving phase, 62 designs including 43 apparels and 19 accessories were emerged. Finally, in evaluation phase, 40 university students majoring design evaluated designs' creativity, function, uniqueness, symbol, aesthetics, and harmony. Through this research, it is expected that fashion products applying Taekuki will be formly established as a fashion item. Furthermore, it is also expected that product development in other categories, brand planning, and product development using other national symbols such as name, anthem, and flower will be followed.

So far, there have been mary studies on human emotions and the emotional side of products in the field of emotional engineering. Contemporary emotion-related researches have focused mainly on the relationship between product aesthetics and the emotional responses elicited by the products, but little is known about emotions elicited from using the products. In this study we have extracted some emotional words that can come up during user interaction with a product and reveal emotional changes. Firstly, we assembled a set of emotional words that were sufficient to represent a general overview of Korean emotions, collected from various literature studies in the field of psychology, linguistics, emotional engineering. Secondly, we found emotional words from collecting user opinion on the website. In this study, we used heavy traffic websites such as shopping mall and mania sites. Finally the emotional words were collected from verbal protocols by using Think Aloud technique. The collected words were integrated according to standards and they were applied on evaluation survey twice for evaluating their appropriateness. This survey was conducted for identification of emotional expressions while using a product. Finally, we extracted 88 emotional words for measuring user's emotions expressed while using products. And we categorized the 88 words to form 6 groups by using factor analysis. The 6 categories that were extracted as a result of this study, such as aesthetics, satisfaction in usability, novelty, uncomfortable- ness, pleasure and excellence were found to be user's representative emotions expressed while using products. It is expected that emotional words and user's representative emotions extracted in this study will be used as subjective evaluation data that is required to measure user's emotional changes while using a product.

The paradigm of a product taking a sudden turn of technical development is due to a change of the needs of diversified user, and this shows that users emphasizes on the value of the sensitivity than the standardized form and usableness of the product, and the value of such a sensitivity can relate to the needs of the product, and it can be filled up eventually by the rapid completion of the product. The creativity will be the most important ability in the future society, it is an added value to all the profession workers which people can use that to increase their competitiveness ability. It is recognized the value of the sensitivity represents the feels psychological aspect of the user and it would be the future design trend, by doing this, products designed would be different from the existing products in the market. I am going to show you that this can be used in the design concept derivation process, there is several core design elements in the product development process, these elements can not only represent the basic user needs but also the user inner unconscious needs, at the same time it keeps the aesthetic concern.

2000 년 이후부터는 HCI 분야에서도 감성적 측면의 연구 중에서 특히 미학(Aesthetics)과 아름다움 (Beauty)에 대한 연구가 활발히 이루어져 왔다. 기존 HCI 분야가 유용성, 사용성과 같은 인지적 측면의 경험 요소들을 추구하기 위해 집중했다면, 최근에는 심미성이나 즐거움 등과 같은 감성적인 측면의 경험 요소도 함께 중시하는 추세이다. 심지어 실용적인 측면을 강조했던 핸드폰이나 냉장고 등의 전자제품에서도 디자인의 심미성과 같은 감성적인 측면이 더욱 부각되고 있다. 현재까지 HCI 분야에서 심미성에 대한 연구가 다수 진행되어왔다. 그 중에서 Tractinsky (2000)는 지각된 심미성과 지각된 사용성이 양의 상관관계를 가짐을 보여주었다. HCI 분야에서 Tranctinsky 와 더불어 Hassenzahl (2004, 2008) 역시 심미성과 다른 사용자 경험 요소들의 상관관계를 밝히기 위해 여러 시도를 해오고 있다. 그러나 상위 연구들은 주로 심미성과 다른 사용자 경험 요소들과의 상관관계에만 초점을 맞추었고, 모두 실험 상황에서만 연구가 진행되었다는 한계점을 가지고 있다. 즉, 실험 상황에서 도출된 결과는 실제로 사용자가 구매 시점이나 사용 상황에서 심미성을 얼마나 중요하게 고려하는지, 심미성 다른 사용자 경험 요소에 어떤 영향을 미치는지, 그 영향력이 사용 경험에 따라 변화가 없는지 사용 정황이 반영된 시사점을 찾기 어려운 실정이다. 따라서 본 연구는 크게 두 가지 목적을 가지고 있다. 첫째, 지각된 심미성이 다른 사용자 경험 요소들에 미치는 영향력을 검증하고, 둘째, 지각된 심미성이 다른 사용자 경험 요소에 미치는 영향력을 사용 경험 기간의 조절효과 관점에서 연구하는 것이다. 우선 본 연구에서는 사용자 경험 요소를 다차원적인 관점에서 접근하여, 여러 사용자 경험 요소들을 실용적 차원과 유희적 차원으로 나누었다. 그리고 사용 경험 기간의 조절효과를 보기 위해, 장기간 사용하는 전자제품을 선정하고 이를 실제로 사용하는 사용자를 대상으로 대규모 온라인 설문을 실시하였다. 결론적으로 본 연구는 Tractinsky(2000)의 기존 연구를 사용 기간의 조절효과 관점에서 진행한 것에 의의를 가질 뿐만 아니라, 본 연구의 결과를 토대로 제품 개발이나 디자인 종사자들에게 HCI 관점의 시사점을 제공하고자 한다.

As men have started to show more desire to express themselves through clothing and accessories also they learn by themselves and take diverse experiences about fashion. At the same time, men's fashion-consciousness is growing together. The role of male consumers' is becoming significant in the fashion market, and there has been more research on their clothes and fashion is increasing, however research on the male casual clothing for their 30~49 years old group is still insufficient. This study aims to examine the casual brands for men in their 30~40s and their characteristics among other men's brands recently appearing in Korea. The results of the study found: first, regarding the questionnaire to give men's casual brand names, 30s males' answers showed clearer recognition about the casual brand than those of 40s males. secondly, the factors affecting attitude of male consumers' towards casual brands are designed 'aesthetics', 'surroundings' and 'price', and the men in their 40s put more important than men in their 30s on 'aesthetics' and 'surroundings'. third, when men were actually buying casual brand, they then took five characteristic factors into account namely: 'the external environment', 'functionality' design 'aesthetics', 'symbolic' and 'price'. Men in their 30s did not show much difference in actual purchase characteristics in regards for the brand factors but men in their 40s showed interest when asked about 'buying product with noticeable brand logo or trademark' item among 'symbolic' factors than men in their 30s (p< .01 of significant difference).

In recent years, the number of foot disease patients due to bad walking habits and living environment is increasing. We examine how patients with mild foot disease according to shoe design characteristics affect satisfaction and purchase intention when purchasing orthopedic shoes. The design characteristics of shoes consisted of functionality, convenience, and aesthetics. It was found that aesthetics had an effect on purchasing orthopedic shoes. Even if the factors of functionality and convenience have little effect, if the aesthetic is high, purchase intention and satisfaction are affected. Various elements are required for design according to the frequency of participation in social activities for each mild foot disease and the purpose of wearing it. It is expected that the development of useful orthopedic shoe designs that patients with mild foot disease can wear in their daily life will lead to practical application and satisfaction by further supplementing the characteristic factors of orthopedic shoe design identified through the research results.

This study investigates the ultimate factor structure of consumer dissatisfaction with the off-line purchase and usage of clothing. It identifies the determinant dimensions of consumer dissatisfaction on clothing purchase and usage and investigates the hierarchical structure of consumer dissatisfaction by assessing and comparing the effectiveness of five alternative factor structure models. A total of 300 women were online-surveyed to assess the level of dissatisfaction based on their dissatisfying experience with clothing purchases and usage in terms of product quality, price, salesperson's attitude, and store environment. The exploratory factor analysis identified the underlying dimensions of dissatisfaction: Handling, Aesthetics, Salesperson, Size, Price, Product Quality, Service, and Environment. By employing a first-order confirmatory factor analysis and higher-order confirmatory factor analysis, consumer dissatisfaction was confirmed to have a hierarchical structure with three second-order constructs Intrinsic instrument is manifested by handling, quality, and size, Intrinsic expression consists of service, salesperson, and environment, and Extrinsic circumstance contains aesthetics and price. On empirically demonstrating the multi-dimensional constructs of consumer dissatisfaction by identifying its hierarchical structure, the study provides the theoretical and practical insights to comprehend consumer purchase and post-purchase behavior. Specifically, it affords an empirical platform to extend the scope of research with condensed concepts of dissatisfaction to researchers. In addition, it also enables marketers to take a broader view of consumer dissatisfaction by providing cues about potential problems and identifying the source of those problems.
