As a measure of the center of data, arithmetical mean, median, mode, harmonic mean and geometric mean are generally used. Students must learn qualitative aspect of average values as well as its calculation for its adequate use. As the result of the learning, they should be able to select the appropriate average value according to the characteristic of data and problem context. For this object, the historical origin and visual interpretation of average values were introduced in this paper. And to help teaching several meanings of average values, several examples including context were suggested.

In DTP systems, satisfactory matching the appearance of displayed image on CRT and that of a reproduced binary image is very important. Most halftoning techniques assume that the printed color dots are square. However, most printers produce roughly circular dots. Thus, there is overlap between adjacent dots, and dots accupy adjcent space that should be empty space. These results are because the significant image distortion on the reproduced images. In this paper, we proposed a new tone correction digital halftoning method based on equi-visual perception characteristic.

A field-sequential color projection system can display color images using panel. However, it suffers from a characteristic trichromatic separation known as "color breakup". The viewing of images exhibiting color breakup may cause visual fatigue and mental stress. In this study, the authors examine, from the standpoint of human factors, the objective and subjective symptoms that can result from the viewing of images with color breakup.

In comtemporary interior design, hybrid form causes cognitive turnovers of aesthetics. Especially it offers much possibility to expression techniques in interior design and works as compound system, symbolic aggregate that makes and expands various meanings. The aesthetic ideology of hybrid design can be interpreted through the philosphic concept of art, sublime, reception, representation and explains expression techniques and characteristic in interior design through various transformation and meaning conversion. The expression techinique that is a form of openness, transcendental interpretation that exceed a dupilicate of meaning. can be classified as oxymoron, defamiliarization and interface. The characteristic that is based on those expressions appears as use of complex codes of visual images, decoding strategy, intertextuality of meaning. This research attitude can explain the thinking method of interior design by defining the epistemological scheme that is basically involved in expressional styles with characteristics of hybrid aesthetics. In order to be recognized as the object of aesthetics, hybrid has to be approached by interpretational methods of expression techniques. Consequently the characters of expression techniques in hybrid design can be investigated as one of the methodology in interior design plan.

The purpose of this study is to develop various designs through renewing and changing perception of accessories by examining various and arbitrary Kitsch. For the method of this study, literature review was mainly used for research of formative characteristics in Kitsch fashion. 798 pieces of work from fashion magazines and website with a focus on Milan, Paris, London and New York collections, in the decade of 2000-2010 were collected. The results of this study are as follows. First, the characteristic of exaggeration is classified into two types: the visual exaggeration, which is characterized by psychological expression through excessive images and (2) the collecting exaggeration, which is not simple but a want of large quantities. Second, the characteristic of satire is classified into two types: (1) the imitation-satire, which satirizes messages to societies with creative humor by using easily consumed materials and (2) the resistance-satire, which is destructive and offensive against isolation and desolation of a capitalistic society. Third, the characteristic of amusement is classified into two types: (1) the playful-amusement, which raises a laugh slyly by using clever materials and (2) the childish-amusement, which involves childish imagination and humor-sense because of desire to be a child. Fourth, the characteristic of nostalgia is classified into two types: (1) the romantic character expressing a departure from modern society, which is desolate because of the urbanization process, and (2) the intermediate character recreating an esthetic category by interacting with different and relative elements. Fifth, the characteristic of inappropriateness is expressed through a deliberate mistake, and it denies existing senses of beauty by overturning common sense and creating new senses of beauty, expressions in distortion and modification of stereotype.

The purpose of this study is to reorganize any rusty image including natural modeling characteristic presented from the natural phenomenon to certain patterns in order to create the fashion design that are valued in the expansion of independently expressional area and modeling art. As a method for research, the author analyzed the concept and characteristic for rust with a base of theoretical background by the documental research and realistic consideration, analyzed its modeling characteristic through domestic and overseas pictures, and e-documents as data, inspected the modeling activities of various categories that various images were adapted related to rust, looked into the concept of Digital Textile Printing and its producing procedure as an expressional method, and analyzed the examples of modern dress and its ornament making use of Digital Textile Printing. The conclusions of this study are as below. First, the rust occurred due to the natural phenomenon is the bond with different material like metal, each unique modeling characteristic occurs and harmony of various patterns has abundant aesthetic value. Second, the author could endowed sensible characteristic and speciality with works and could produce creative fashion design that painting, abstractive pattern and harmony of unique sense of colors are significant by using the image of rust, Third, to emphasize natural feeling of rust, the author could develop creative design that simple silhouette and impressive pattern look significant by reorganizing and applying rust according to repetition, increment, rhythm, contract, emphasis and harmony. Fourth, Digital Textile Printing method is used to induce visual effect by the expression of feels of rust, and the author could express the natural patterns, delicate expression for the feels of a material and unique design of emotion.

In photoreceptor cells, light activates visual pigments consisting of a chromophore (retinal) and a protein moiety (opsin). Activated visual pigments trigger an enzymatic cascade, called phototransduction cascade, in which more than ten phototransduction proteins are participating. Two types of vertebrate photoreceptor cells, rods and cones, play roles in twilight and daylight vision, respectively. Cones are further classified into several subtypes based on their morphology and spectral sensitivity. Though the diversities of vertebrate photoreceptor cells are crucial for color discrimination and detection of light over a wider range of intensities, the molecular mechanism to characterize the photoreceptor types remains unclear. We investigated the amino acid sequences of about 50 vertebrate opsins, and found that these sequences can be classified into five fundamental subfamilies. Clear relationships were found between these subfamilies and their characteristic spectral sensitivities. In addition to opsins, we studied other phototransduction proteins. The amino acid sequences of phototransduction proteins can be classified into a few subfamilies. Even though their spectral sensitivity is considerably different, cones fundamentally share the phototransduction protein isoforms which are different from those found in rods. It is suggested that the difference in phototransduction proteins between rods and cones is responsible for their sensitivity to light. Isoforms and their selective expression may characterize individual photoreceptor cells, thus providing us with physiological functions such as color vision and daylight/twilight visions.

The objective of this study was to investigate the accuracy of visual discrimination of soft fat pork carcasses when subjecting carcasses to quality grade evaluations. In addition, the quality of the longissimus dorsi muscle from soft fat carcasses was investigated. Iodine values of back fat from soft fat carcasses evaluated by visual discrimination were significantly higher than those from firm fat carcass (p < 0.05). However, those values were lower than the standard for soft fat (iodine value = 70). There were no significant differences in linoleic acid content, b-values, and L-values (p < 0.05) of back fat between firm and soft fat carcasses evaluated by visual discrimination. Color of longissimus dorsi muscle from soft fat carcasses (iodine value higher than 70) was not different from that of firm fat carcass (iodine value lower than 70). Except for linoleic acid, there were no significant differences in any fatty acid contents between longissimus dorsi muscles from firm fat and soft fat carcasses. Monounsaturated fatty acid content of longissimus dorsi muscles from soft fat carcasses was significantly lower than those of firm fat carcass (p < 0.05). However polyunsaturated fatty acid content was significantly higher (p < 0.05) in longissimus dorsi muscles from soft fat carcasses. In conclusion, visual discrimination results for soft fat pork carcass were inaccurate. Therefore, other indicators should be required to evaluate soft fat pork carcasses. In contrast, the quality of longissimus dorsi muscle from soft fat carcasses was superior in terms of fatty acid composition compared with that of firm fat carcasses.

The term 'modern', in broader sense, refers to the concepts like modernity, modernization, modernism and the like, which came from Westernization impling the recognition of indigenous culture as being inferior to Western culture by comparison along with the expanded influences of the Empire of Japan. These concepts, however, rather than evolving from Western standards, came into being as a form of civilization led by Japan which had already tasted the fruits of modernization by 1920s. Since 1920s, the policy of, so-called, reconstructing Asian countries by Japan came to create eastern way of modernism, as a new East Asian trend mainly revealed in China which was against colonization after Japan's invasion and conquest of Manchuria. Therefore, Eastern' modern' unlike Western one could be understood in the widespread terminology, 'Modern(摩登)' in Shanghai, reflecting consciousness like 'Fashion' or 'Trend' in female images on a variety of visual media. By 1930s it was the most notable that 'modern' was accepted as something similar with 'Fashion', or 'Trend' in sociocultural contexts. These atmosphere had led commercial arts to enable to communicate with the public in a great deal of supports and success in Shanghai which was widely regarded as the citadel for the inflow of Western culture, among which transformations in female images were remarkable as a representative form of culture. It is also remarkable that 'historical modernity' transforming from the feudal age to modern society was considered a synchronic modernity, and nationalism was regarded as a sort of being modern, while involved in the newly-changed female images as a fashion mode. Changes in fashion including hair style in Shanghai by 1930s, as a way of expressions showing what was modern through commercial artistic productions, were easily noticed in visual media as an outlet of modern women's inner desire revealing their pursuit for new mode of life in metropolitan cities. As a characteristic of the time creating a new code of visual female images, it is notable that there existed another form of 'modern' satisfying socio-cultural needs of the general public seeking for being 'modern'.
