Rapid development of electronic technology has made it possible to perform various function. But this technology made it increase it's complexity. Therefore, It was important to identify usability problem in interface design. The quality of interface to promote the efficient interaction should be evaluated with regard to users' cognitive characteristics. So, in this paper, washing machine, that is one of the most useful electronic home application was studied menu structure on interface and it's operational states transition. At first, an cognitive menu structure is identified with users' conceptual similarity of the main function of washing machine. Then three washing machines was selected to compare with the cognitive menu structure. And, we were analyzed how operational state of the washing machine was transfered. As a result, we can be revealed that menu operational method based on the cognitive structure was consistent with the user's preferred operational method during the experimental tasks and the users and designers had a different knowledge of an it's function structure. These results will be useful to design the washing machine interface.

감성정보를 디자인 활동에 필요한 정보로 활용하기 위해서는 전체 디자인 프로세스에서 사용자를 최초 컨셉 단계에서부터 참여시켜 관찰 및 평가에 적극 동참케 하는 사용자 참여 디자인이 매우 효과적이다. 이러한 감성 정보 수집 및 평가를 통한 상용자 인터페이스 디자인 개발 프로세스를 MP3 CDP를 대상으로 적용하여 연구를 진행하였다. 최근의 MP3CD Player들은 일반 음악 CD들이 10여곡에서 많게는 20여곡 정도의 분량을 가지고 있는 것에 비해 그 분량이 최고 100여곡 이상에 이르고 있다. 그럼에도 불구하고 MP3CD Player들은 기존의 일반 음악 CD Player의 UI를 소극적으로 수정, 변경하여 사용하고 있는 상황이다. 본 연구는 자체적인 곡 분류방법을 제시하고 있는 ‘H’사의 MP3CD Player를 선정하고 이를 기준으로 초기 디자인에 사용자를 참여시켜 사용자 감성 정보 및 요소들을 효과적으로 평가하여 사용자 중심 디자인을 극대화 시키는 방법을 모색하였다. 제품의 최초 기능 분석시에는 카드인덱스(Card Index)방식을 이용하여 기능을 그룹핑하고 인터페이스를 개선하였으며 이를 토대로 프로토타입을 완성하였다. 이를 사용자가 직접 조작하는 방식을 관찰 분석하여 평가 결과를 토대로 UI 디자인가이드라인을 제시하였다.

표준으로 정의된 IT제품의 보안성 평가 방안들은 CC나 ITSEC, TCSEC과 같이 많이 나와있다. 그러나 이러한 표준은 너무 추상적이고 소프트웨어의 각 단계에 따른 보안성을 측정하는데 불충분하다. 또 SSE-CMM같은 프로세스를 평가하는 방법의 경우 역시 너무 추상적이고 포괄적인 면만을 설명하였고 프로세스 자체에 대한 평가에 중점을 두었을 뿐 각 단계의 보안강도를 평가하는데는 부족하다. 이 논문에서는 이러한 단정을 보안하고자 각 공정단계에서, 특히 제품을 계획하는 단계인 요구분석단계와 디자인 단계에서 그래프 모델링과 모듈 다이어그램 통한 검증방법을 제시하였다. 여기서는 보안 운영체계라고 특정 제품을 명시하였지만 실제로 다양한 IT제품에 적용될 수 있다.

In this research, we executed a questionnaire survey targeting men and women in 20' or more who reside in the metropolitan area and have experienced purchasing the vehicles in order to study how Promotion Mix Activity affects Brand assets, and ultimately what kind of relation it has with Purchase intention. In the statistical process of collected data, we analyzed the data by using SPSS 12.0 for Windows statistical package and AMOS 7.0 program. As the result of analysis, first, when we analyzed the relation of the Promotion Mix Activity and Brand Assets of the companies, the more affirmative the assessment on the advertising activities of the companies was, the higher the brand popularity, royalty and image increased, And it appeared that as the assessment on PR activities of the companies got more affirmative, the brand popularity, image and royalty increased. Second, as the result of the analysis of the relation between salespersons' Promotion Activities and Brand assets, it appeared that salespersons' social capacity improved Brand awareness and royalty and their strategic capacity improved Brand awareness, royalty and image. Third, seeing the result of the analysis on the relation between Brand assets and Purchase intention, it was shown that Brand popularity had a meaningful positive(+) effect upon satisfaction and repurchase(oral) intention, and Brand royalty had a meaningful positive(+) effect upon satisfaction and repurchase(oral) intention. In addition, it appeared that Brand image had a meaningful positive(+) effect upon satisfaction and repurchase(oral) intention, and finally it could be known that Brand assets had a close correlation with Purchase intention. Therefore, this research established the color marketing strategy as follows. First, we shall build up the functional role such as aesthetic favor, information communication, protection of ecosystem, publicity reinforcement etc. so as to emphasize the properties of the package design; second, we have to construct the color marketing strategy to convey the images of the commodity besides the psychological and physiological utility which colors grants, the utility used in visual conveyance as communication media; third, we should build the color marketing strategy for the integration of company image; finally we have to compose the colors fitted for the company and product style and introduce design marketing using company colors.

The purpose of this study is to estimate the determinants of product design and analyze the impacts of product design on quality competitiveness, product reliability, and consumer satisfaction in an attempt to provide a foundation for the theory of design management. For this empirical analysis, this study has derived the relevant measurement variables from a survey on 400 Korean manufacturing firms during the period of $August{\sim}October$ 2003. The empirical findings are summarized as follows: First, the determinants of product design are very significantly (at p<0.001) estimated to be the R&D capability, the level of R&D expenditure, the level of innovative activities(5S, TQM, 6Sigma, QC, etc.). This empirical result can support Pawar and Driva(1999)'s two principles by which the performance of product design and product development can be simultaneously evaluated in the context of CE(concurrent engineering) of NPD(newly product development) activities. Second, the hypothesis on the causality: product design${\rightarrow}$quality competitiveness${\rightarrow}$customer satisfaction${\rightarrow}$customer loyalty is very significantly (at p<0.001) accepted. This implies that product design positively affects consumer satisfaction, not directly but indirectly, by influencing quality competitiveness. This empirical result of this study can also support the studies of for example Flynn et al.(1994), Ahire et at.(1996), Afire and Dreyfus(2000) which conclude that design management is a significant determinant of product quality. The aforementioned empirical results are important in the following sense: the empirical result that quality competitiveness plays a bridging role between product design and consumer satisfaction can reconcile the traditional debate between QFD(quality function development) approach asserted by product developers and conjoint analysis maintained by marketers. The first empirical result is related to QFD approach whereas the second empirical result is related to conjoint analysis. At the same time, the empirical results of this study can support the rationale of design integration(DI) of Ettlie(1997), i.e., the coordination of the timing and substance of product development activities performed by the various disciplines and organizational functions of a product's life cycle. Finally, the policy implication (at the corporate level) from the empirical results is that successful design management(DM) requires not only the support of top management but also the removal of communication barriers, (i.e. the adoption of cross-functional teams) so that concurrent engineering(CE), the simultaneous development of product and process designs can assure product development speed, design quality, and market success.
