V.M.D(Visual Merchandising Design) covers every space, environment, and visually stimulating factor. This includes not only the architectural appearance but interior, graphic sign boards, window display, layout, store appliances, lighting, and even the looks and service attitude that sales employees have and show to customers. V.M.D aims to display merchandise in multiple ways; to heighten brand images; to steadily lure many customers to the store. One of the characteristics that V.M.D has is, that this abandons the previous design concept which solely puts stress on luxurious interior-focused display; that this displays merchandise in a rational and systemic way and induces customers to buy products. In this regard, the objective of this study is to study brand perception and effect of V.M.D displayed in the stores, on customers, and thereby to present the concepts of V.M.D, suitable for display in the stores, which can be used continuously in the future.

The noise sources of a Hyperion image are mainly due to the atmospheric effects, the sensor's instrumental errors, and A/D conversion. Though uncalibrated, overlapping, and all deep water absorption bands generally are removed, there still exist noisy bands. The visual inspection for selecting clean and stable processing bands is a simple practice, but is a manual, inefficient, and subjective process. In this paper, we propose that the extrema ratio be used for noise estimation and unsupervised band selection. The extrema ratio was compared with existing SNR and entropy measures. First, Gaussian, salt and pepper, and Speckle noises were added to ALI (Advanced Land Imager) images with relatively low noises, and the relation of noise level and those measures was explored. Second, the unsupervised band selection was performed through the EM (Expectation-Maximization) algorithm of the measures which were extracted from a Hyperion images. The Hyperion data were classified into 5 categories according to the image quality by visual inspection, and used as the reference data. The experimental result showed that the extrema ratio could be used effectively for band selection of Hyperion images.

Digital close-range photogrammetric technique can measure and describe 3D geometric farm from 2D image. This technique is increasingly applied in the field of sciences. In the fields of civil and mechanical engineering, which need precise measurements for design, expensive measuring equipments are widely used. In occasions where visual inspection is required in addition to other forms of measurements, appropriate measuring equipments have not been yet available. This study utilizes digital close-range photogrammetric technique to quantitatively analyze behavior patterns before and after destruction from test model of reinforced-soil wall. Then the results are compared with the measurements obtained using digital theodolite to verify the reliability of the proposed method.

The purpose of this research was to identify the components of scaffolding in open inquiry and to explore the functions of teachers' scaffolding, which is necessary to support students' open inquiry. In order to identify scaffolding components, at first, we conducted a survey using a questionnaire on what students think about open inquiry on 110 students who performed open inquiry in two middle schools, and then carried out factor analysis based on the survey results. It was attempted to investigate students' perception through focus group interviews corresponding to scaffolding components that were identified through factor analysis. Also, we examined teachers' empirical view of scaffolding functions in open inquiry through in-depth interviews with four teachers. The results of exploratory factor analysis revealed that there were five scaffolding components of open inquiry: motivation, planning, strategy, environment and participation. The results of focus group interviews showed that students experienced difficulties in planning, strategy, environment and participation components, except for motivation component. In particular, students asked for support to strengthen the participation component, which means recognizing their role, active participation and collaboration with peers. Meanwhile, the results of in-depth interviews with teachers showed that teachers' empirical views of scaffolding function in open inquiry were categorized as cognitive (conceptual, metacognitive), emotional (motivational, arbitrative) and strategic. Interviewed teachers preferred the strategic scaffolding and cognitive scaffolding to the emotional scaffolding. Based on the results, we also discussed the implications for performing open inquiry effectively.

Art is the product from the combination of politics, economy, and social and cultural aspects. Recent development of digital media has affected on the expansion of visual expression in art. Digital media allow artists to use sound and physical interaction as well as image as an plastic element for making a work of art. Also, digital media help artists create an interactive, synaesthetic and visual perceptive environment by combining viewers' physical interaction with the reconstruction of image, sound, light, and among other plastic elements. This research was focused on the analysis of the relationship between images in art work and the viewer and data visualization using sound from the perspective of visual perception. This research also aimed to develop an interactive art by visualizing physical data with sound generating from outer stimulus or the viewer. Physical data generating from outer sound can be analyzed in various aspects. For example, Sound data can be analyzed and sampled within pitch, volume, frequency, and etc. This researcher implemented a new form of media art through the visual experiment of LED light triggered by sound frequency generating from viewers' voice or outer physical stimulus. Also, this researcher explored the possibility of various visual image expression generating from the viewer's reaction to illusionary characteristics of light(LED), which can be transformed within external physical data in real time. As the result, this researcher used a motif from Piet Mondrian's Broadway Boogie Woogie in order to implement a visual perceptive interactive work reacting with sound. Mondrian tried to approach at the essence of visual object by eliminating unnecessary representation elements and simplifying them in painting and making them into abstraction consisting of color, vertical and horizontal lines. This researcher utilized Modrian's simplified visual composition as a representation metaphor in oder to transform external sound stimulus into the element of light(LED), and implemented an environment inducing viewers' participation, which is a dynamic composition maximizing a synaesthetic expression, differing from Modrian's static composition.

1973년 사우디 아라비아의 주베일(Jubail)산업항 건설프로젝트의 해상 철구조물을 제작하기 시 작한 이래, 당사는 30여개의 해양 구조물 공사를 수주, 이 분야에 있어 상당한 경험을 갖게 되 었다. 해양 구조물은 육상 구조물에 비하여 가혹한 환경중에 설치되는 관계로 설계난 제작에 있어 보수적인 경향이 강하다. 다시 말하면, 발주자의 시각에서 본 새로운 설계 개념이나 제작 공법등이 쉽사리 적용되지 않으며, 전통적으로 안전하다고 여겨지는 방법만을 고집하는 경우가 허다한 것이다. 이러한 와중에서도 엔지니어들은 자신들의 경험과 지식을 밑바탕으로 좀더 적 극적 방법을 모색하고자 하였으며 그러한 노력은 오늘날에도 계속되고 있다. 본 고는 해양 구 조물 용접의 일반적 현상에 대하여 기술하고 금후의 나아갈 바에 대하여 고찰코자 한다.

We can anticipate that animations will form one of the axes and lead popular culture in our future visual age. Recently, research has been actively conducted, but it mainly focuses on their value in culture industry or technologies and methods of producing animations. Of course, research that deals with animation characters has constantly come out. This study focuses on the 'formative elements' of 3D animation characters and attempts differentiation from other research by inducing new logic theoretically. Being freed from the research on characters that has been merely focused on theoretical grounds, this study intends to figure out how audience that is consumers who actually get to watch and feel animations recognizes them and find out related problems and also solutions for them. In particular, this study intends to examine the formative characteristics of 3D animation characters with the characters appearing in , one of the animations that have achieved artistic value as well as commercial success. And for that, the study conducted not only literature review but various surveys and Delphi method as well. Also, the researcher devised an analysis frame to evaluate the formative elements through in-depth discussion with experts. And with this, the study created the forms such as the Elements of Form, Formation Methods of Form and Visual Recognition Elements of Form, examined how audience recognized 3D characters. The process of recognizing an image is influenced by socio-cultural environment or sex, age, and the level of knowledge differently. This was meant to investigate current visual culture and the public's perspective through characters in that represent the visual mode.
