The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using Off-Line Programming System. A proposed visual calibration scheme is based on position-based visual feedback. The visual calibration system is composed of a personal computer, an image processing board, a video monitor, and one camera. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test, and construction of simple silhouette figures. Then, camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection, which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.

Through this study, I explored a creation of the postmodern furniture aesthetics through the transformation by student's interpretation in experiencing the art/craft/handmade/studio furniture aesthetics in postmodernism theoretically for 'wood culture experience class' or 'wood love experience class' by the Korea Forest Service because the class tends to focus on making simple wood works involved just in the practical part. Qualitative conceptual analysis as the principal methodology was used to achieve the theoretical context in the experience programs. Following the lesson one on defining the postmodern aesthetics in New Design furniture as metaphor and the lesson two on interpreting an aesthetics of art and everyday life with the wood furniture which expresses the metaphorical and symbolical aesthetics appeared as New Design furniture in postmodernism in the previous papers, I developed lesson three on creating an object using eco-friendly materials like wood in transforming an aesthetics of postmodern furniture as the final stage of the study. Therefore, the students will be able to create a piece of eco-friendly wood furniture for our environment as metaphor transformed by his/her perspective regarding a piece of selected New Design furniture.

The theories of optical/haptic perception provide us contrasting insights into the perception of space in movie and architecture. Through the lenses of these theories, this study aims to analyse the optical and haptical aspect of the medieval library of the film, The Name of the Rose. The dominance of vision over the other senses has been maintained by many philosophers, such as Plato, Aristotle, and Aquinas, and this trend leads to the development of the hierarchical and perspective space of Renaissance and Modern Architecture. Those conceptions of optical space help us not only identify space as clear and distinct three-dimensional entity but also separate the subject and the object. However, tactile/haptic perception is more useful to explain the experience of film and contemporary architecture than optical perception. This haptic space is developed by Alois Riegl, Walter Benjamin, and Gilles Deleuze. This study intends to search for the difference between two perceptions on the architectural space of the movie, examine the relation between architecture and human, space and user.

The Daseinsanalytic understanding of somatization as a phenomenon begins with a question about the real nature of human body. The human body is primarily not an object of scientific study, which is based on the dichotomy of mind and body, but it is an existential body(Leiblichkeit) disclosing the meaning of Beingness of human being. Since the meaning always discloses itself in man's relations with his world, his body in existential nature expresses his relations with the world. Such a somatic expression of world relations is the phenomenon of somatization whose meanings are illuminated by phenomenological method, which is unlike the method adopted by natural science investigating the cause and effect.

Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.

The strategy through visual sense is one of the ways that subject builds the outside world and communicates. The visual sense seems higher level of dependence than the other senses and contributes to intercommunication. For this reason, the desire of image dates back to primitive art and visual image(visual media and visual culture) has dialectically developed in the history of mankind. Visual subject, based on perspective of Renaissance, was moved from God to human beings. Andre Bazin's 'la genese automatique' through technical art has epochally changed the paradigm of visual art and visual culture. From primitive art to photo and film, the image, based on visual sense, has reflected human wish, appealed visual desire and led to evolution of image. In the late 20 century, without dialectical evolution of technology and culture, rapidly progressive digital image has changed social and cultural implication over rational strategy of production and distribution and it strengthened authority of image through visual approach of endless desire. The goal of this study is to analyze the value change of digital image developing a new Renaissance through production, reading, communication, and implication of evolution due to digitalized image, which has evolved as object and tool of desire.

This research takes as its object a body of historical researches by a new generation of French architects in the 1970s, who tried to confront the deep crisis in architecture since the years 1960. The research begins by noting that the ideology of the architect as an autonomous and transcendental subject, an ideology held by the architects of the previous generation, was a main target that young architects wanted to criticize and overcome. From this observation, the research focuses on a antihumanistic project which gave basis for a significant number of historical researches on modern architecture and was the result of a reappropriation of the French structuralism intensively developed in the human and social sciences of that time in France. After a series of textual analyzes, we argue that a new perspective on the city and the relationship of the latter with the architecture on the one hand, and the proposal for an "modest" architect as an alternative figure after rejection of the autonomous and transcendental one on the other hand, have been derived as the outcome of anti-humanist historiographic works. Finally, we assume that these historical adventure gave conceptual basis for postmodern architecture in France, freed from the modern myth of unity of author and that of work of art, but tinted by a moralism requesting modesty to architects.

These new Phenomenon influences with the new terminology 'fusion' on the way of our life in all areas of our society including the clothes and foods. Along with post-structuralism, which aims at diversification and senses deconstructionalism is a characteristic of this time post-structuralism is based upon the deconstructionalism. Especially the arts in the modern society which is called an information-oriented society lack the totality of a text and become fragmentary, and therefore it follows that traditional values are destroyed and at last a new code such as fusion which is incomprehensible if we would be in mono-linear perspective. Dislikes toward excessively formative and orthodox elements of modern pictures and constructs ; features of kitschs and subcultures against materialism are revealed in diverse objects and materialism. In such a situation of mingling of diversifications with no time to evaluate an object, another diverse forms come into the world and there is no room for evaluating. Therefore, this study will make a light on what are tendencies in the fashion design from the end of 20C to the beginning of 21C, and foreground the concept of fusion in modern fashion which is relevant with digitals and its generative background.

This paper proposes a 3-D pose (positions and orientations) estimation system based on the recognition of circular ring patterns. To deal with monocular vision-based pose estimation problem, we specially design a circular ring pattern that has a simplicity merit in view of object recognition. A pose estimation procedure is described in detail, which utilizes the geometric transformation of a circular ring pattern in 2-D perspective projection space. The proposed method is evaluated through the analysis of accuracy and precision with respect to 3-D pose estimation of a quadrotor-type vehicle in 3-D space.
