For several decades, attribute classification methods using the asymmetrical relationship between an attribute performance and the satisfaction of that attribute have been explored by numerous researchers. In particular, the Kano model, which classifies quality attributes into 5 elements using simple questionnaire and two-dimensional evaluation table, has gained popularity: Attractive, One-dimensional, Must-be, Indifferent, and Reverse quality. As Kano's model is well accepted, many literatures have introduced categorization methods using the Kano's evaluation table at attribute level. However, they applied different terminologies and classification criteria and this causes confusion and misunderstanding. Therefore, a criterion for quality classification at attribute level is necessary. This study is aimed to suggest a new attribute classification method that sub-categorizes quality attributes using 5-point ordinal point and Kano's two-dimensional evaluation table through an extensive literature review. For this, the current study examines the intrinsic and extrinsic problems of the well-recognized Kano model that have been used for measuring customer satisfaction of products and services. For empirical study, the author conducted a comparative study between the results of Kano's model and the proposed method for an e-learning case (33 attributes). Results show that the proposed method is better in terms of ease of use and understanding of kano's results and this result will contribute to the further development of the attractive quality theory that enables to understand both the customers explicit and implicit needs.

The purpose of this study was to analyze the physiochemical properties of blackberry fruit beverage(BFB) and to develop a descriptive analysis procedure for evaluating the sensory characteristics of BFB. The amount of soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of BFB were determined. All BFB samples demonstrated significantly different physicochemical properties(p<.01). Ten highly trained panelists identified the following eleven sensory attributes in the BFB and defined by standardized terminology for each attribute; turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, throat hit, refreshing, as well as astringent grade for textural characteristics. There were significant differences in all the eleven sensory attributes of the BFB samples(p<.001). Descriptive terminology used in the BFB analysis was capable of classifying the sensory attributes of the BFB. Based on these results, the analysis method and sensory evaluation techniques used in this study could be reasonably applied to other fruit beverages for establishing similar physiochemical characteristic and descriptive sensory attributes.

본 연구의 목적은 우리나라 학생들의 인지적 속성의 특징을 인지진단이론에 근거하여 국제적인 수준에서 비교 분석하고 우리나라 교육에 주는 시사점을 찾는 것이다. TIMSS 2011의 평가틀에 근거하여 9개의 인지 속성을 추출하였고 TIMSS 2011의 과학 문항 216개에 대해 각 문항이 어떠한 인지 속성들을 요구하는지 판단하여 Q행렬을 작성하였다. 총 5차례의 검토와 수정을 반복하여 타당도를 점검하고 최종적인 Q행렬을 작성한 후, 다층 IRT 분석을 실시하여 인지 속성에 따른 국가별 특성을 파악하였다. 분석을 통해 나타난 우리나라의 인지적 속성을 TIMSS 2011의 과학성취도 상위 15개국과 비교한 결과 우리나라 학생들에게 모형사용하기, 자료분석하기, 결론도출하기, 평가 및 정당화하기는 쉬운 속성에 해당하였고 회상/인식하기, 설명하기, 분류하기, 통합하기, 가설설정 및 실험설계하기는 어려운 속성에 해당하였다. 우리나라 학생들이 가장 쉬워하는 인지 속성은 자료해석하기였고 가장 어려워하는 인지 속성은 설명하기였다. 우리나라의 경우 쉬운 인지 속성의 대부분은 비교국 중에서 가장 쉽게 여기고 어려운 인지 속성은 가장 어렵게 여기는 것으로 나타나 극단적인 특성을 보였다. 따라서 특정한 인지 속성이 많이 활용되도록 하기 보다는 여러가지 인지 속성이 골고루 활용되도록 과학 교육과정과 과학 교과서를 구성할 필요가 있겠다.

Design Problems are often both multidimensional and highly interactive. Very rarely does any part of a designed thing serve only one purpose. The activity of designing is thus a goal-directed activity and normally a goal-directed problem-solving activity. This means, problem solving is finding a way to get from some initial situation to a desired goal. Designers are transforming agents within a society whose goals are to improve the human condition through physical metamorphosis. Many theorist have agreed that designing involves problem solving or decision making. Accordingly evaluation plays an essential role in design activity. The evaluation factors include all attributes that have levels specified by quantitative and qualitative objectives Alternatives in multi-objective decision prOblems generally possess numerous attributes by which they can be described and compared. The evaluation factors include all attributes that have levels specified by quantitative and qualitative objectives. However since qualitative factors are difficult to quantify as numeral estimates, these factors have tended to be ignored without regard for their importance to human content. We adapted the Accumulative Evaluation Model as an evaluation algorithm for IDES. Industrial Design Evaluation System (IDES) consists of 3 major modules ( 1 Design Element, 2.Matrix, 3.Evaluation). It is intended to be an aid for design evaluation. The luther thinks IDES is a new design evaluation approach which could provide effective rating of design values to make value judgements. It is an attempt to provide industrial designers with access to design evaluation. The author's aim is to produce an Object-Oriented Evaluation System which can guide the designers and decision makers under complex design projects. It uses\ulcorner an Object-Oriented Programming for this prototype, Because of managing complexity (Flexibility and Reusability) and improving productivity(Extensibility & Maintainability and Programming by User) in software development process. The author has chose the C++ because it is a hybrid, rather than pure Object-Oriented Language.

The aim of this study was to provide strategic implications for the coffee market in which competition got severer through IPA analysis based on the attributes of selection of a specialized franchise coffee shop. The results of a positive analysis conducted with undergraduates in their twenties were as follows: According to the evaluation of the importance of the attributes of selection of a specialized coffee shop, the most important were 'cleanliness and hygienic facilities inside the shop (6.09)' and 'taste and quality of the menu (coffee) (6.09)'. According to the performance analysis, those showing the highest performance were 'brand image (4.92)' and 'cleanliness and hygienic facilities inside the shop (4.92)'. According to the result of IPA analysis, what customers regarded as being the most important were 'taste and quality of the menu (coffee)', 'kindness of the staff', and 'cleanliness and hygienic facilities inside the shop', and, in fact, they showed great performances as well. However, 'price of the menu (coffee)' was regarded as being important but did not indicate a great performance; therefore, they showed dissatisfaction with it. Although they did not think 'environment around the shop', 'brand image', 'brand recognition' or 'interior size and scale of the shop' were important, the attributes did not appear to show great performances. Therefore, we need constant maintenance strate gies regarding the fact that consumers are considered to be very important for evaluation, and should make efforts to change the price in advance.

Evaluation is to be seen a~ a central component of design activity. It is an attempt to ensure that the proposal which arises is accepted and that the resulting artefact itself suited to its purposes in practice. Recent surveys of Evaluation show that most methods require quantitative and explicit attributes. Always a significant part of the attributes of design proposals is qualitative. Therefore we need some study that convert qualitative attributes into quantitative scale values, because in many cases con\ulcornerclusions can be drawn about the order of the overall value of the design proposals. Following to Thurstone's psychological scaling methods, attributive values are assigned by ruting scale methods, met, hod of rank-order and method of paired comparisons. The problem of psycho\ulcornerlogical scaling is then to determine whether the stimuli can be ordered on a psychological continuum with respect to the degree of the attributes each possesses. The law of comparative judgement assumes that for a given stimulus there is associated a most frequently aroused or modal discriminal process on a psychological continuum. This paper is based upon the premise that the modal discriminul process will also be the same as the mean or median of the distribution.The objective of this paper is to argue for an acceptance of qualitative approaches to the evalua\ulcornertion of Design as a complement to the existing quantitative techniques. The scale values of 10 attri\ulcornerbutes \ulcorner(1) originality, (2) aesthetics, (3) satisfaction, (4) effeciency, (5) function, (6) size, (7) texture, (8) simplicity, (9) symbol, and (10) facility) in case of TV sets are obtained and their interactions are examined.

The paper is to analyze multi-attributes for expanding new renewable energy in agricultural sectors which have environmental, technical, economic, and social factors consisting of 15 attributes which have both positive and negative impacts. We applied the analytic hierarchy process (AHP) to data from opinion polls. As a result of the AHP survey, the overall results indicate that the respondents more weight on economical factor than environmental, technical, and social factors for expanding new renewable energy. At the lowest level, a comparison of individual 15 attributes within three factors shows that fixed cost highest in multi-attributes, followed by operating cost, technical superiority. To achieve the public acceptance about expanding new renewable energy in agricultural sectors, the policy-makers should take all relevant factors into account through the decision-making process by the public opinions.
