JOURNAL FREE ACCESSThe differences of percieved qualities of traditional paper in Japan and in Korea were Studied by means of SD-methods for 25 younger subjects (ages : 30-39) and 25 older subjects (60-69) in each country. We investigated using 11 paired/adjectives, i.e. three for visual qualities, three for tactile qualities, two for boundary qualities, and three for fancy and decision qualities. Results were analyzed by means of correlation coefficients and slopes of primary regression line in the relations between practical value and percieved quality or between percieved qualities. One of the most important results was the estimation method of the qualities. All Japanese subjects tested the traditional papers after checking the tactual sense. On the other hand, the Korean subjects did them visually. There are remarkable differences in the synthetic qualities in each country. Many Japanese like thin, soft, light, and fine-fiber paper. Korean people, however, like glossy and high density paper.View full abstractDownload PDF (1506K) -

JOURNAL FREE ACCESSThis study proposes to use formative images as indicators for design and evaluation of manhole covers by considering the features and problems of their design process, to confirm their validity, and to identify the relation between the formative images and the design components. Seven image words that express the formative images of the composition of the ground manhole covers were abstracted from a questionnaire survey conducted among five in-house designers. Images of eight samples were evaluated after replacing the design motifs with geometric shapes by five in-house designers and six contract designers, who actually design the manhole covers, and then the validity of these words was verified based on the result of evaluation. The role of formative images as common indicators was confirmed as there was no difference between the results of evaluations by the in-house designers and the contract designers. The relation between formative images and design components was identified by the theory of quantification (I), and the indicators for design proposals of manhole covers were obtained.View full abstractDownload PDF (1529K) -

JOURNAL FREE ACCESSIn this study taking up twelve kinds of safety sign the relationship between their shapes and the recognition evaluation of the frames was examined using the paired comparison method. The types of the frame shapes were four (frameless, circular, triangular and square). The result showed that the effectiveness of a frame and the shape of a frame exerted influences on the evaluation of the safety signs to show danger, appropriateness and discrimination. It was proven that the circular frame was suitable for having the sign recognized to be more danger, and that the triangular frame and the square one were suitable for the recognition. Moreover, when the shapes of the frame are chosen, the intended purposes such as prohibition, warning or indication should be considered. It may be better to use the square frame as the prohibition mark. The choice of the warning mark or indication mark depends upon the priority given ; danger or discrimination ; when danger has priority over discrimination, it is advisable to use the circular frame, and if discrimination has priority over danger, the triangular or square frame was found out to be serve its purpose.View full abstractDownload PDF (1049K) -

JOURNAL FREE ACCESSIn this study we tried to extract space formation elements, which leave a deep impression, by a continuous notation method called "CONTINUOUS RECORD". By comparing the changing visual images of the real space with the notation, we make clear the tendency of each formation element, the relationship among spatial change and notation, and the notation trend of the street formation differences. As a result, concerning human visual information change according to movement, it became clear that in a small spatial formation chage outstanding objects have a priority of notation. However, in a bigger change of the investigated space, the same objects do not have the same priority of notation. The notation precedes the images of the real space in moving toward a wider street. In the case of moving between sections with a different degree of spatial opening, the number of notations shows a tendency to decrease and the same trend we noticed if objects are arranged in a similar way.View full abstractDownload PDF (1323K) -

JOURNAL FREE ACCESSSupport concerning the color was not considered though design support system (MSCS_2D, MSCS_3D) which output the figure to become the prototype of the shape idea had been constructed by now. The fuzzy rule had been identified up to now in the sense though a fuzzy inference was used for the center of the system in MSCS_2D and MSCS_3D, and it was not able to be said that the method was scientific. Then, to identify a fuzzy rule concerning the color, the use of fuzzy neural net work was attempted here. As a result, it was able to be confirmed to be able to obtain an appropriate rule concerning the color. Therefore, it has been understood that it is appropriate to use the fuzzy neural net work as a means to identify the fuzzy rule used for MSCS_2D and MSCS_3D.View full abstractDownload PDF (718K) -

JOURNAL FREE ACCESSThis study delineated the structure of the refrigerator line-ups of the four major manufacturers during the past two decades. Refrigerators were classified by the functions and layouts of the compartments, since particular importance was attached to the components in the development of refrigerators. The result revealed that there were 22 combinations of the functions, or 48 types if the difference in layout was considered. The line-ups of the manufacturers were described by 48 types, and analyzed in time series by the quantification theory III. It was confirmed that the manufacturers developed their unique line-ups and deployed them discretely by the periods. Although the line-up changes were continuous within a period, there were two types of changes, continuous and consecutive, when their occurrence extended over plural periods. In terms of time series, the 48 types were classified into three groups; the basic type group, the trendy type group, and the limited period type group. The line-ups were structured by combinations of these types.View full abstractDownload PDF (1410K) -

JOURNAL FREE ACCESSThis report relates to a part of an application of measurements of feature parameters and shape factors of symbols. Recently symbols such as trademark or CI have been developed worldwide and the necessity of the studies of designing, similarity or originality of them has increased. To investigate the relative position of symbols about some phase of shapes in the numerous and widespread population of symbols, a trial was made to spread out and observe the samples on the plane (XY-coordinates, selected two factors). In this study, two kind of perimeters were used as XY-axes. A date-base system was made on the basis of these figures. Symbols which might have desired shapes can be searched out from the data base by giving values of these figures as a reference data.View full abstractDownload PDF (1354K)
