일반적인 문헌/문서나 웹페이지에서 창조에 도움이 되는 아이디어와 준아이디어를 색출하기 위하여 아이디어 마이닝 기법을 적용하였다. 아이디어 마이닝과 의견 마이닝 및 논제 신호 마이닝에서 사용하는 발췌 기법으로 웹 페이지, 문헌, 문서 등에 포함되어 있는 아이디어를 발췌하였다. 발췌 기법을 (1) 결정적 단서 어구, (2) 단서 멀티미디어, (3) 문맥 신호, 및 (4) 담화 구절 방법으로 정리하여 7가지 아이디어 유형 -사상, 계획, 의견, 글, 그림, 소리, 공식 별로 실험하였다. 각 기법들의 효율성은 재현율과 정확률을 혼합한 F 측정값으로 판단하였고 (1), (3), (4) 방법은 대체로 긍정적인 평가를 얻었다. 특히, 결정적 단서 어구는 아이디어 적출에 문맥 신호는 준아이디어 추출에 효과적인 것으로 판단되었다.

Objective : The present study was intended to develop a design ideation and evaluation process for the development of ecology-, ergonomics-, and economy-friendly ($E^3$-friendly) products. Background : Due to increasing social and legal requirements on global sustainability, manufacturing companies have made more efforts ever than before for the development of eco-friendly products. However, most eco-friendly products are often criticized due to lacking ergonomic and/or economic considerations. Method : An $E^3$-friendly product development process consisting of (1) survey of eco-friendly products, (2) characterization of eco-friendly products, (3) design ideation for $E^3$-friendly product, and (4) design idea evaluation for $E^3$-friendliness was established and applied to the development of a novel product which supports drinking of daily recommended amount of water. Results : Fifty-five design characteristics were identified by a survey of forty eco-friendly products and incorporated into the proposed ideation and evaluation process. New ideas and design changes were developed effectively using the proposed development process for a novel $E^3$-friendly bottle for support of water drinking. Conclusion : The proposed process was found effective for the development of eco-friendly design ideas and improvements. Application : The proposed system would be of use to develop better design ideas having market competitiveness.

Data envelopment analysis (DEA) has proven to be a useful tool for assessing efficiency or productivity of organizations which is of vital practical importance in managerial decision making. While DEA assumes exact input and output data, the development of imprecise DEA (IDEA) broadens the scope of applications to efficiency evaluations involving imprecise information which implies various forms of ordinal and bounded data possibly or often occurring in practice. The primary purpose of this article is to characterize the variable efficiency in IDEA. Since DEA describes a pair of primal and dual models, also called envelopment and multiplier models, we can basically consider two IDEA models: One incorporates imprecise data into envelopment model and the other includes the same imprecise data in multiplier model. The issues of rising importance are thus the relationships between the two models and how to solve them. The groundwork we will make includes a duality study which makes it possible to characterize the efficiency solutions from the two models. This also relates to why we take into account the variable efficiency and its bounds in IDEA that some of the published IDEA studies have made. We also present computational aspects of the efficiency bounds and how to interpret the efficiency solutions.

Affordance is a kind of mental physiology, used by psychologist Donald A. Norman as a design idea, defined as "the property that something can directly and essentially provide something to a person or animal". This idea of returning to the essence and providing properties intuitively has a new guiding effect on product design. The purpose of this thesis is to take the theory of affordance as the basis of design concept, and redesign the shape of desktop lamps in small home appliances, so as to optimize the product shape. A product styling design method based on the concept of affordance is established through four major classifications of affordance, and a styling design scheme is completed using a tabletop luminaire in small home appliances as an example, and then a product styling design evaluation system is used to evaluate the new tabletop luminaire styling design scheme and the existing styling, and the evaluation results are analyzed. Finally, it is concluded that a new product styling design method based on affordance is constructed, and the feasibility and effectiveness of this method are verified, which provides ideas and theoretical basis for product styling design.

The purpose of this study was to suggest the idea for IAQ improvement of university dormitory through space analysis and residents' evaluation. The data was collected from 105 Konkuk university dormitory residents by a questionnaire survey. As a result, the idea for IAQ improvement of university dormitory can be suggested. First, it was found that it was necessary to improve size of windows and to exchange bathroom exhaust system for ventilation. Secondly, it is important for resident to ventilate and clean their room. Thirdly, the educational program for dormitory residents about maintenance of IAQ was esssentially needed. Also, it is necessary to manage air conditioning equipment maintenance and bathroom hygiene.

설계VE수행 시 아이디어 창출을 할 경우 브레인스토밍의 특성상 산발적으로 아이디어를 제안하게 된다. 이 과정에서 유사 아이디어를 중복적으로 제안할 수 있으며, 중복적으로 창출된 유사 아이디어는 각각 다른 평가 및 분석으로 이어지게 된다. 이렇게 창출된 유사 아이디어는 효율적인 분석/평가가 쉽지 않으며, 아이디어의 타당성 및 객관성을 검증하기가 어렵게 된다. 이로 인하여 많은 시간을 소비할 뿐만 아니라 객관적인 평가가 어려워지게 된다. 아이디어 창출을 하기 위한 준비단계를 완벽하게 수행 하였으나, 실질적인 VE활동에서는 아이디어 창출 및 관리가 어려운 실정이다. 이에 본 연구는 아이디어를 보다 효과적으로 창출하고자 설계VE활동의 효과적인 아이디어 창출 및 관리를 위한 프로세스 모델을 제시한다.

This paper presents a methodology for analyzing individual differences on Kansei evaluation for a set of product samples. This analysis divides subjects into several groups by each subject's Kansei evaluation data according to what kinds of Kansei are related on what kinds of design elements. The basic idea is to classify the results of cluster analysis in individual subject's ranges. A similarity matrix of subject is computed by comparing dendrogram of each subjects. The methodology is applied to analyzing evaluation data of cellular phone design.
