This study intends to understand the visual experience of architectural space generated by users' movement based on the interpretation of visual properties. An analytic theory of Isovist is suggested for the objective and comparable measurement for such visual experience, and a computer program for the analysis has been proposed as well. By using the analytical theory and computer program, eight houses designed by Adolf Loos and Le Corbusler are analyzed for the purpose of understanding the visual characteristics of the Modern Architecture and the contemporaries. The result shows that, while the architectural space of Loos emphasizes personal privacy as for being livable spaces, the architectural space of Corbusier emphasizes users' movement as for including diverse visual arrays. These commensurable results exhibit that the analytical tool and research frame suggested in this study can be a competitive tool for such analysis.

The purpose of this study is to analyze the characteristics of exhibition circulation through the movement pattern. It looks into the factoers under the influence with the visitor's movement. The method of analysis of investigation by following after visitors. The viewing behavioral of exhibition based on the time, speed, proportion of appreciation is classfied into three types of the profound, the general, the passing viewers. The characteristics of the viewing form of these patterns largely depend on the space elements which are the structure form. And particularly the position of exit, the width of exhibition space and the connection of exhibition space stand out the disparity of the factor of the spatial structure These three patterns bring about a lot of encounter in the exhibition space according to the difference of these routes consequently. So appropriate to the each pattern can offer visitors to more effective environment of exhibition.

The complex 2-dimensional movements of fish during an annual migration circuit were generated and simulated by a chaotic model of fish movement, which was expanded from a small-scale movement model. Fish migration was modeled as a neural network including stimuli, central decision-making, and output responses as variables. The input stimuli included physical stimuli (temperature, salinity, turbidity, flow), biotic factors (prey, predators, life cycle) and landmarks or navigational aids (sun, moon, weather), values of which were all normalized as ratios. By varying the amplitude and period coefficients of the klinokinesis index using chaotic equations, model results (i.e., spatial orientation patterns of migration through time) were represented as fish feeding, spawning, overwintering, and sheltering. Simulations using this model generated 2-dimesional annual movements of sea bream migration in the southern and western seas of the Korean Peninsula. This model of object-oriented and large-scale fish migration produced complicated and sensitive migratory movements by varying both the klinokinesis coefficients (e.g., the amplitude and period of the physiological month) and the angular variables within chaotic equations.

A portable mould oscillation analyzer with an integrated computer, developed by POSCO, records the movement of the mould in every spatial direction. The system uses the gap sensors to measure the mould movement (displacement) in two horizontal directions according to the mould narrow and broad faces and the vertical strokes in the four corners of mould. The gap sensor is a non-contacting minute displacement-measuring device using the principle of high frequency eddy current loss. The mould oscillation diagnostic system integrates the gap sensors, their converters and the industrial portable computer with plug-in data acquisition boards. In an own expert module, which is included in the diagnosis program, one can obtain much information about the mould oscillation equipment.

An analytic axial xenon oscillation model was developed for pressurized water reactor analysis. The model employs an equation system for axial difference parameters that was derived from the two-group one-dimensional diffusion equation with control rod modeling and coupled with xenon and iodine balance equations. The spatial distributions of nu, xenon, and iodine were expanded by the Fourier sine series, resulting in cancellation of the flux-xenon coupled non-linearity. An inhomogeneous differential equation system for the axial difference parameters, which gives the relationship between power, iodine and xenon axial differences in the case of control rod movement, was derived and solved analytically. The analytic solution of the axial difference parameters can directly provide with the variation of axial power difference during xenon oscillation. The accuracy of the model is verified by benchmark calculations with one-dimensional reference core calculations.

From ancient times to today the formation of centrality in architecture has taken very important role as an organizing device. However after 19th century modem architecture focused on the universal aspect and homogeneity of space, and developed its own vocabulary through de-centralization. Since 1960's the reflections on de-humanized space of modem space have been evloved. As those movement has been understood seriously, the centrality can be changed to phenomenological one. And The phenomenological centrality maintains organic balance with its surroundings not trying to form a hierarchic system. So it shows human-oriented tendency and facilitates experiential movements of human body. And it also gives a sense of being. The phenomenological centrality is comprised of center, boundary, and two types of axis. The characteristics of phenomenological centrality can be analyzed as practical and meaningful center, visible boundary, experiential movement, and unexpectable encounters with spaces and nature.

In large commercial facilities, customer movements have a close interrelation between space structure and interior environment elements. With the importance of the spacial structure, VMD strategy has recently played greater role In the interior environment image to satisfy customers' needs. This study intends to examine the relationship among customer behavior, customer movement, and VMD by grasping customers shopping behavior characteristics that come from the relatively comprehensive factors in the female sections of the department stores through the environmental image that is composed of spatial and emotional elements. This study also serves the purpose that by tracking shopping time, shopping speed, and the ratio of shopping depth that directly reflects customer behavior characteristics, various causes, either general or specific, which can affect the decision on purchase are to be examined. Based on this research results, we bring up the basic data and foundation for floor MD plan, establishment of movement plan, and VMD plan at a store.

A TIN, Triangulated Irregular Network, based topographic modeling method and a distributed rainfall-runoff model using the topographic representation is presented. In the TIN based topographic representation, a watershed basin is modeled as a set of contiguous non-overlapping triangular facets: the watershed basin is subdivided according to streamlines to deal with water movement one-dimensionally; and each partitioned catchment is approximated to a slope element having a quasi-three-dimensional shape by using cubic spline functions. On an approximated slope element, water movement is represented by combined surface-subsurface kinematic wave equations considering a change of slope gradient and slope width. By using the distributed rainfall-runoff model, the effects of spatial variability of soil properties on runoff response are examined.

The 'spatial senses' mean environments and the instinctive responds to objects in the environments. The infancy is an important period to develop the basic capacity of the 'spatial senses'. Since young children can develop the 'spatial senses' throughout the actual and active search, it is essential for them to do experience through their physical actions. This paper proposes four motion based-contents for improving the spatial sense of young children: a bubble game, a cyber goalkeeper game, a mud-huddle game, and a shape recognition game. The proposed four games are implemented to the virtual learning environments. Also, the virtual learning environments utilize the realistic interfaces which can recognize motions of young children and then interact with the games as they do the movement at the virtual environments provided. Using the realistic interfaces not only develops young children's spatial sense but also offers them the pleasure and interest of self-study.
