Although a figure expression has a role of mediator in the geometry proof, it is not admitted to prove based on a vision-dependent feature. This study starts from the problem that although a figure expression has an important role in the geometry proof, a lot of students don't understand the limit of vision-dependent feature in the figure expression. We will investigate this problem to understand cognitive characteristic of students. Moreover, we try to get the didactical implications. To do this, we investigate the cognitive ability for a limit of vision-dependent feature, targeting a class of middle school seniors And we will have a personal interview with four students who show a lack of sense of limit of vision-dependent feature in the figure expression and two students for who it is difficult to judge that they don't understand the limit of vision-dependent feature in the figure expression. We will observe and analyzed the cognitive characteristic of six students. Based on the analysis, we will finally discuss on the didactical implications to help students understand the limit of vision-dependent feature in the figure expression.

The purpose of this study is to be applied with the basic data for the design method in the housing space which is differential. So, we analyzed the expression method and the application characteristic to materials of units in housing complex. To that, we researched on the condition of finishing material about the kind of material, color, texture and pattern for components in living room space. The results of this study are as follows : First, at the present time, the Object concept is expressed by 'mixing' and 'juxtaposition' of material, texture and pattern of finishing materials in housing space. But, we could find that the Object concept was used restrictively in housing space. So, we have to find different expression methods to be the effective and differential design by being applied Object concept for the housing space. Second, the 'mixing' which is the method to express the Object concept is showed in only 'art wall'. so, we can estimate that the method is the limited method to plan the varied housing. It is needed various expression methods to design components for the housing space. Third, it showed that the 'mixing' was a passive expression method using a little differential for design of housing space. We could estimate that similar methods were applied to the housing design. By results of this study, we can think that the develop study is needed to find design methods for expression of the Object in housing space.

This study was to suggest the construction of work and expression authority records for FRBRization. ICP, FRBR/FRAD and RDA as the content rules were referred as the framework for the construction of work and expression authority records. LC RDA authority records examples, JSC of RDA authority examples, and VIAF work and expression authority records were analyzed as case studies. 5 findings were suggested. First, authority records consist of name, work, and expression authority records which are inter-related. Second, the construction of authorized access points was suggested according to 5 work types. Third, the consideration in describing work attributes as separate element and as part of an authorized access point, and other distinguishing characteristic of the work were suggested. Fourth, the consideration in describing expression attributes as separate element and as part of an authorized access point, and other distinguishing characteristic of the expression were suggested. Fifth, 5XX was suggested for linking between work and expression. This study would contribute to revise KCR4.

In the late twentieth century, the multistory housing has become the most preferred housing type. Moreover, in multistory housing design, not only interior design but also exterior design, uniqueness and characteristic have been added as significant factors in design to break simplicity and uniformity. The purpose of this study is to understand the tendency of the elevation design in Europe and to suggest the idea for elevation design for domestic. Also, each elements of elevation were analyzed through classification and schematization which categorized by its own characteristic. Design elements can be classified into three categories. They are corresponding with inner spaces, emphasizing visual expression of exterior material and texture, and presenting aesthetic factors of building shape. Those are named as the Spatial Externalization, the Visual Expression, and the Expression of Building Shape. In this frame nineteen elevations of sixteen different cases were analysed. As a result of case studies, it is clear that elevation designs were not standardized and each cases has its own characteristics. Also it showed how the each design elements can be coordinated as a total design and how they expressed identities of each housing. This study could contribute to motivate diversifying the design of multistory housing.

This study considers types of expression and examines aesthetic characteristics through analyzing designs (such as the Coca-Cola contour bottle as fashion) which has actively progressed in the collaboration of fashion designers and fashion brands. The conclusions of this study are as follows. The types of fashion expression on the Coca-Cola contour bottle are a presentation of diverse fashion images through a digital print expression that allow people-friendly images to be three-dimensional (or by adding a formative element) and the use of accessories or clothes. The symbolism characteristic were first indicated for the aesthetic characteristics on the Coca-Cola contour bottle. Symbolism is indicated through the identification of an implicit meaning towards a specific object. The symbolism of fashion was highlighted by designing the Coca-Cola's contour bottle with a typical material and pattern pursued by fashion designers and fashion brands. Second, the characteristic of playfulness was presented to expresses the instinctive desire in human nature for pleasure. The expression of visual playfulness is emphasized through the combination of item and image or by changing and re-analyzing a form through refuting stereotypes. Third, the characteristic of femininity was shown to express beauty in external image or a woman's delicate and soft inner propensity. Femininity was created by presenting a sensual femininity that recognized the voluminous curve silhouette of the Coca-Cola bottle such as a sexy female body or through the combination of a women's inner beauty with the sensory image of the object.

This study considers types of expression and examines aesthetic characteristics by analyzing images expressed through space directing at Chanel Fashion Shows. The conclusions of this study are as follows. The expression types on space directing at Chanel Fashion Shows are what is presented by distributing huge objects associated with Fashion Shows at the center or back of the stage, integrating several detailed decorative elements while maintaining the morphological characteristics of the runway in a linear form, and utilizing an inartificial place or newly forming the whole stage. The symbolism characteristic was first indicated for the aesthetic characteristics on space directing at Chanel Fashion Shows. Symbolism is indicated through the identification of an implicit meaning towards a specific object. The symbolism was highlighted utilizing elements or stories that have a deep association with Chanel. Second, the characteristic of ecology was expressed through the recognition of the importance of the ecological environment by escaping the harmful practices of civilization such as environmental disasters and human alienation. The expression of visual ecology was emphasized utilizing themes related to environmental disasters or reviving the space of primitive nature. Third, the characteristic of fantasy was shown to express thoughts that originated from the human yearning for the ideal world contrary to an incomplete society. Fantasy was created by the inaccessible object in reality and a change in spatial structure. Fourth, the characteristics of amusement expressed pleasure, which is the instinctive desire truly immanent in a human being. It was natural amusement, which was advocated as freedom through the integration of neutrality, integrating either diverse elements (which are naturally recognized in our daily life) into Fashion Shows or amusement, which expressed newness through utilizing unusual objects in Fashion Shows.

In creating an illustration, rather than depend on the subjective expression of the illustrator, one should consider the characteristics of child cognitive development. Illustrations should be those which can arouse child's interesting and which can be educational. To do this, first, characteristic expressions shown in children's pictures can be used to arouse child's interesting. In creating an illustration, one should consider sufficiently "intuitive form" and "representative form" in order to appeal to curiosity of child. Second, illustrations should be able to be helpful to the development of child's intellect, emotion and imagination. The form is desired to be adequately exaggerated or reduced feature, to have anthropomorphic figure and to be fantastic composition considering the egocentrism and animalism of the child. As mentioned above, it can be said characteristic expression in picture book illustrations are affected by the two points - fascinating expression drawn by child and expression by illustrator, which can be helpful to the development of intellect, emotion and imagination.otion and imagination.

This paper describes the design program of duct silencer. Duct silencer is used ventilating system. Variables in the program for predicting transmission loss are width of splitter, airway width, perforate plate, absorption material and frequency. Generally used expression for predicting transmission loss has something that don't think about frequency characteristic. Therefore we propose the new expression that considered frequency characteristic. In the 1/1 octave band center frequency, the expected weighting number(K) is fitted with absorption ratio and airway width. The fitted 2nd degree polynomial expression is based on the test data performed in YOUIL Industrial Corperation. This program's accuracy is about 90 percent.
