The purpose of this study is to examine whether the visual materials presented in the science textbooks coincide with those visual materials that are preferred the most by students. After analyzing the visual materials presented in the unit "Molecular Motion and Change of State" of science textbooks for the first grade of middle school, questionnaires by teaching-learning process are made. Thereafter, students are requested to select those types of visual materials that were preferred by them by process and describe their reasons for the selection. According to the results of the survey of students' perception, students at the high science achievement level prefer those visual materials that were presented conceptually and implicatively, while students at the low science achievement level prefer concrete and detailed visual materials. Except for the learning motivation process, the proportion of non-preferred visual materials is higher in the remaining processes and those visual materials that were presented in the science textbooks are much different from those visual materials that were preferred by students.

This study analyzed the ways of expressing materials to create visual perception spaces in "commercial spaces". The result is as follows. First, it has been discovered that expressing materials in commercial spaces plays an important role in creating various visual perception spaces as well as discriminative spaces, in commercial spaces. Hence, it will be necessary to make a multilateral study on how you can express materials to create visual perception spaces. Second, by referring to earlier studies, four types of space have been deduced as visual perception spaces. These are: "expansion", "central", "borderline" and "decoration" spaces. Third, by considering the space types and characteristics as well as the expressing materials, the criteria for the ways of expressing materials to create visual perception spaces in commercial spaces. Finally, looking at these expression methods, images of "expansion" spaces have most commonly been expressed indistinctly by using the materials and patterns. The profound images of "central" spaces were displayed using the materials and their symbolic images have been shown using the materials and colors. In the "borderline" spaces, the areas have been distinctly segmented or expressed in limited spaces by using the materials and colors. Visual designs were displayed in the "decoration" spaces by using materials from other space fields. All these phenomena have demonstrated that various new materials are being used to create various distinctive designs in commercial spaces. The result of this study shall act as basic reference materials in devising visual designs needed in creating various visual perception spaces.

The purpose of this study is to analyze the expression method and visual characteristics of material utilized the lighting in terms of a visual aspect. The method of study is to establish standards for analysis and to classify type of visual effect and expression of that focused on preliminary study. And It is to grasp the visual expression characteristics of new materials. through analysis standards. The results of the study are as follows. First, 'decorativeness', 'symbolization', 'motion-images' and 'interactivity' were selected as the type of visual expression through the precedent studies. And it was classified the visual effects as 3 types like 'a light-emitting effect', 'steric effects' and 'movement effect'. Second, We could know that 'light-emitting effect' was expressed in 7-new materials, 'three-dimensional effect' was expressed in 3-new materials, and 'motion effect' in 4-new materials. Through that. We could know that the new materials represented with 'light-emitting effect' are much more than the other new materials. Third, the results of this study show that 'decorativeness' in the visual types was appeared to 'light-emitting effect' and 'three-dimensional effect'. 'symbolization' to 'light-emitting effect' and 'motion effect', 'motion-images' to 'three-dimensional effect' and 'motion effect' and 'interactivity' to 'light-emitting effect', 'three-dimensional effect' and 'motion effect'. And It was appeared to three effects in 'interactivity'. We could know that it is more effective to be presented the visual effect simultaneously to communication with the visual perception.

The new computer program, visual SolidMech (ver 2.0), for mechanics of materials and structural mechanics has been developed using visual C++. The visual SolidMech is organized in a format similar to most standard texts on mechanics of materials and structural mechanics. This program consists of a number of menus to perform various calculations as well as a set of dedicated graphical user interfaces. Solutions to problems are given in both graphical and numerical forms. The visual SolidMech will help students develop problem-solving skills by showing them the important factors affecting various problem types, by helping them visualize the nature of internal stresses and member deformations, and by providing them an easy-to-use means of investigating a greater number of problems and variations. This new program can be utilized as a supplement to existing texts in mechanics of materials and structural mechanics.

In this study, the characteristics of the reading materials in elementary school science textbooks developed under the 2009 revised National Science Curriculum were investigated. The criteria for classifying the reading materials were the types of topic, purpose, students' activity, and presentation. The visual images in the reading materials were also analyzed from the viewpoint of type, role, caption type, and proximity type. The results indicated that the number of the reading materials in the 2009 revised science textbooks decreased compared to that of the 2007 revised science textbooks. It was also found that the frequencies of the reading materials expanding concepts of the text and/or requiring corresponding students' inquiry increased. More visual images were used in the reading materials of the 2009 revised science textbooks. However, several limitations were still found to exist; most visual images were illustration and/or picture; many visual images were presented without a caption; there was a problem in the proximity of visual image to text.

The purpose of this study is to discuss about the role of the visualization as an effective method of teaching abstracted mathematics, to analyze visual materials in middle and high school mathematics and to suggest various visualized materials for teaching mathematics effectively. Though formal, symbolic and analytical teaching method is a major characteristic of mathematics, the students should be taught to understand through intuition and insight, and formalize the mathematical concepts progressively. Especially the sight is one of the most important basics of cognition for intuition and insight. Therefore, suggesting mathematical contents through the visual method makes the students understand and formalize the mathematical concepts more easily. In this study, we tried to investigate the meaning and role of visualization in mathematics teaching. And, we discussed about the four roles of visualization in the process of mathematics teaching and learning confirmation and memorization of the mathematical truth, proving theorem and solving problems which is one of the most important purposes of teaching mathematics, According to the roles of visualization, we analyzed visual materials currently taught in middle and high school, and suggested various visual materials useful in teaching mathematics. The investigated fields are algebra where visual materials are little used, and geometry where they are use the most. The paper-made-textbook can't show moving animation vigorously. Hence we suggested visual materials made by GSP and applets in IES .

This study analyzed metaphorical characteristics of composite materials in terms of a visual aspect on a new material that is applicable for housing space. The results are as follows. First, the recent trend of housing space tends to stimulate emotions of residents through visual finishing materials, and for this reason, visual expression of a new material that is applicable to finishing materials plays an important role. Second, convertibleness, association and duplicity were selected as items of metaphorical expressions through the precedent studies. Third, most of combinations of materials were shown different from the existing materials in an expressive characteristic of composite materials through analysis, and application of a technology showed a different visual effect of patterns and textures from the existing materials. This implies that visual expression and directing are being attempted using such technology on finishing materials of housing space with development of digital technologies. Fourth, for metaphorical characteristics of composite material for housing space, combination of various materials and a digital technology were applied on convertibleness. For association, a combination of materials that have each different characteristic associated with the third material, and combination with subsidiary material of optical fiber and a digital technology were appled for duplicity. Data obtained from the results of this study has high efficiency in planning finishing materials for emotional housing space in future, and it will be basic data for a study on development of new finishing materials.

The output and usage rate of audio-visual materials have sharply increased as the information industry advances and diverse archives became available. However, the awareness of the audio-visual archives are more of a separate record with collateral value. The organizations that hold these materials have very weak system of the various areas such as the categories and archiving methods. Moreover, the management system varies among the organizations, so the users face difficulty retrieving and utilizing the audio-visual materials. Thus, this study examined the feasibility of the synchronized management of audio-visual archives by comparing the descriptive elements of the audio-visual archives in internal key agencies. The study thereby examines the feasibility of the metadata element of the organizations and that of synchronized management to propose the effect of the use of management, retrieval and service of efficient AV materials. The study also proposes the improvement of descriptive element of metadata.
