제품 디자인 기술의 발달로 다양한 컨셉의 제품들이 개발되고 있고 사용자 맞춤형 디자인 컨셉에 따른 제품이 활발하게 출시되고 있다. 성공적인 개발을 위해서는 컨셉을 제품 개발 프로세스에 정확히 전달하여야 목표하는 디자인을 개발할 수 있다. 제품 개발 목적에 맞는 디자인 컨셉을 찾기 위해서 붐박스를 겸한 모바일 폰에 대한 디자인 컨셉을 감성적 어휘 표현으로 찾아내고 해당 목표에 맞는 시각적 이미지를 이용하여 컨셉 목표를 구체화했다. 컨셉 목표를 구체화하기 위하여 개발에 참여하는 이해당사자가 서로 합의할 수 있는 이미지를 선정을 목표로 참여자 간의 의견 조율을 위한 테스트를 실시하였다. 본 연구에서는 합리적인 선택을 위하여 테스트 결과를 클러스트링 기법을 이용하여 컨셉과 이미지 선정을 위한 방법을 제안하고자 하였다. 이러한 방법은 디자인 컨셉을 설계하고 목표에 맞은 GUI 구현에 기여할 것으로 보인다.

Concurrent Engineering(CE) has presented new possibilities for successful product development by incorporating various product life-cycle functions from the earlier stage of design. In the product design, geometric representation is vital not only in its traditional role as a means of communicating design information but also in its role as a means of externalizing designer's thought process by visualizing the design product. During the last dozens of years, there has been extraordinary development of computer-aided tools intended to generate, present or communicate 3D models. However, there has not been comparable progress in the development of 3D-CAD systems intended to represent and manipulate a variety of product life-cycle information in a consistent manner. This paper proposes a novel concept, Minus Volume (MV), to incorporate various design information relevant to product lift-cycle functions. MV is a functional shape that is extracted from a design object within a bounding box. A prototype 3D-CAD system is implemented based on the MV concept and illustrated with the successful implementation of concurrent design and manufacturing.

The recent humidifier disinfectant disaster has caused a great change in our society and lead the Korean people to lose faith in the government and corporations. To overcome this mistrust, the government and corporations have undertaken certain efforts, including a voluntary agreement on consumer product safety. All the ingredients of a consumer product should be disclosed according to this voluntary agreement. There were also unexpected benefits occuring from this process. We found that the concept of corporate responsibility for product safety differed greatly among the various actors in Korean society. Corporations believed that a product could be considered safe if it contained no regulated substances. We have come to believe that this may be an important cause of the humidifier disinfectant disaster. The Korean government, corporations, and civil organizations have reached a consensus that it is a corporation's responsibility to evaluate the risks of products before they are introduced to the market. However, the limitations of these voluntary efforts are clear, and the legal system needs to be improved. We suggest that the concept of extreme recklessness should be introduced into regulations on product safety.

In order to overcome the limitation of market orientation concept, Narver et al. (2004) have extended the original concept into two dimensions, responsive market orientation (RMO) and proactive market orientation (PMO), respectively. Yet, there has been very limited empirical studies that analyzed the differential effects of each market orientation on firm outcomes, especially in the Korean context. We analyze the impact of RMO and PMO on the new product performance in the perspective of SMEs and examine the moderating effect of external factors such as environmental uncertainty and market similarity. The results of this study show that both RMO and PMO have a significant positive effect on the new product performance of SMEs. Also, environment uncertainty shows a negative moderating effect on the relationship between RMO and new product performance, whereas it has positive moderation with PMO. This suggests that focusing on potential customers' needs rather than current needs helps improve firm performance as the competitive environment surrounding the firm becomes more uncertain. Lastly, market similarity showed a positive moderating effect on the relationship between RMO and new product performance, but not on PMO.

The purpose of this study was to create a theoretical structure for the concept of purchasing risks by identifying the structure of purchasing risks that lead to obstacles in the purchasing decisions of consumers in fashion consumption via online channels. This was a secondary research using books, articles, prior researches, and academic journals on the five topics of "characteristics of fashion consumption," "the concept of purchasing risks," "purchasing risks by product types," "purchasing risks by channel types," and "purchasing risks of fashion consumption on online shopping channels." According to the arguments of prior researches, the study divided the purchasing risks of fashion consumption through online shopping into four categories : (1) fundamental purchasing risks including financial risk and time loss risk pertaining to any product or channel, (2) online channel purchase risks, which include risks in payment, Information leaks, and delivery and return/exchange risk, (3) fashion product risk related to product quality or experience of other people, which includes social risks and risks associated with quality, and (4) the online channel${\times}$fashion product risks, which include the aesthetic and psychological hazards especially amplified in online channels. The four risk factors were then described with a concept map to systemize the multi-dimensional and stereoscopic psychological structure of purchasing risks. Of the four risk factors, consumers placed the most emphasis on the online channel${\times}$fashion product risks, hence, reducing this risk factor is of utmost priority for marketing of online shopping channels.

PL(product liability) is a major social, market, and economic force. The legal obligation of manufacturers and sellers to compensate for injury or damage caused by defective products is not a recent phenomenon. The concept of Product liability has been in existence for many years, but its emphasis has changed recently. This PL prevention program has shown that the two area of product quality assurance one is a PLD(product liability defense) and the other is a PLP(product liability prevention.

Conceptual design is the first step in the overall process of product design. Its intrinsic uncertainty, imprecision, and lack of information lead to the fact that current conceptual design activities in engineering have not been computerized and very few CAD systems are available to support conceptual design. In most of the current intelligent design systems, approach of principle synthesis, such as morphology matrix, bond graphic, or design catalogues, is usually adopted to deal with the concept generation, in which optional concepts are generally combined and enumerated through function analysis. However, as a large number of concepts are generated, it is difficult to evaluate and optimize these design candidates using regular algorithm. It is necessary to develop a new approach or a tool to solve the concept generation. Generally speaking, concept generation is a problem of concept synthesis. In substance, this process of developing design candidate is a combinatorial optimization process, viz., the process of concept generation can be regarded as a solution for a state-place composed of multi-concepts. In this paper, genetic algorithm is utilized as a feasible tool to solve the problem of combinatorial optimization in concept generation, in which the encoding method of morphology matrix based on function analysis is applied, and a sequence of optimal concepts are generated through the search and iterative process which is controlled by genetic operators, including selection, crossover, mutation, and reproduction in GA. Several crucial problems on GA are discussed in this paper, such as the calculation of fitness value and the criteria for heredity termination, which have a heavy effect on selection of better concepts. The feasibility and intellectualization of the proposed approach are demonstrated with an engineering case. In this work concept generation is implemented using GA, which can facilitate not only generating several better concepts, but also selecting the best concept. Thus optimal concepts can be conveniently developed and design efficiency can be greatly improved.

In the current product and fashion design, the 'eco-friendliness' is affecting practically and conceptually on all the sectors of industry and culture. Therefore, this study seeks to examine specific values in the concept of eco-friendly design. The subjects of this paper are studied on the scholarly journals, and are confined to those from 1990, when naturalism and ecology trend started to be in product and fashion, to the moment of search of February 2009. This study used 'Naturalism', 'Green', 'Environment-friendly', 'Eco', 'Sustainable', 'Well-being' and 'Lohas' as key words for the search. Analysis is performed by content analysis and the unit of analysis was based upon the adjectives, nouns and phrases which is related key words in the concept of eco-friendly design. The study realized that there are personal value, environmental value, economic value, and social value in the concept of eco-friendly design. In the result, it is not enough to consider the effect on environment only. Understanding the personal, environmental, economic, and social value from the viewpoint of customers, finding the optimal design factors, and reflecting them in development of product and fashion are necessary to pave the way for advanced eco-friendly design. The results of this paper would help to the future product and fashion development for eco-friendly brands.

Objective: This study presents the conceptual framework and the conceptual model to account for user experience by expanding the existing concepts of usability, in particular considering the user-interface environment in digital convergence. Background: To better understand a variety of users interacting with a converged product based on digital technologies, there seems to be a limit to consider the existing concepts of usability. All possible aspects of user's interaction with a product in a context of use need to be taken into consideration. Method: This study identifies the concept of user experience through a comprehensive literature review. Results: First, this study reviews the existing concepts of usability and user experience. And then this study describes four main components in the conceptual framework of user experience: user's internal states, user's external states, a product, and various outcomes, each of which encompasses distinct sub-components. The conceptual model of user experience accounts for how user's internal states change over time and for how different sub-components affect actual behavior of use. Conclusion: It is expected that these user experience concepts can be used in basic resources to better understand different behavioral characteristics of users and to better design interactive products in converged digital environments.
