When one enters a space, perceives the material geometry of that space. Walking inside buildings or across the city is generating a geometry of moving bodies that fills the space. These two geometries coexist: a static geometry of the space and an invisible one of the moving bodies. The space that we actually experience, whether interior or exterior, is a continuous network of voids. Individuals' movement will fill the network of voids that we understand as "the city". Our environment of voids and borders is organized by the means of architecture and urbanism. The geometry generated by motion affects both the limits and the voids, thus space can be defined by the tandem of the moving bodies and their environment. We propose in this study a mean of investigating users' movement and thus understanding the qualities of space while introducing the concept of space scores as analytical maps and design tools.

Moving object segmentation is a fundamental function for content-based application. Moving object edges are produced by matching the detected moving edges with the current frame edges. But we can often experience the object edge disconnectedness due to coincidence of similarity between the object and background colors or the decrease of movement of moving object. The edge disconnectedness is a serious problem because it degrades the object visual quality so conspicuously That it sometimes makes it inadequate to perform content-based coding. We have solved this problem by developing a robust and comprehensive edge linking algorithm. And we also developed an automatic moving object segmentation algorithm. These algorithms can produce the completely linked moving object edge boundary and the accurate moving object segmentation. These algorithms can process CIF 30 frames/sec in a PC. These algorithms can be used for the MPEG-4 content-based coding.

As life is changing, modern people are interested in culture life more than the past and as a result Art Exhibition increases. Nowadays many methods of exhibit are introduced, especially Direct experience. Trick Art Experience exhibition introduced Direct experirence to a work of art for interests and used props, objets, images, and sounds for maximizing experience element. Trick Art Experience exhibition added humor as imitating famous painting and gave a deep impression through the optical illusion technique which make flat structure look three-dimensional structure. Recently, demands for Experience exhibition which are like Trick Art increase. This study figure out pros and cons through a comparison analysis of direction and component about Trick Art Experience exhibition and find a check list about making an audience active about experience. From now on, we have an object about showing design data including customer satisfaction measurement to make various expressions of direction and component about Experience Art through a case analysis. We have firsthand visited case spaces to experience the spaces and prepared a check list for the relevant types of expressions. Referring to the exhibit work classification system, components that correspond to Trick Art Experience exhibition were grouped according to constituting items. Among the types of expressions, the levels of satisfaction with Experience exhibition and Participating exhibit were found to be high and the level of satisfaction with Heart Moving exhibit was found to be low through surveys. Among the components, the levels of satisfaction with stereograms and formative effect elements were found to be high and those of spatial changes and media effects were found to be low through surveys. Therefore, the expressions should be reinforced and the components should be improved.

The purpose of this research is to develop a virtual reality system which enables to actually experience the virtual reality through the visual sense of human. TSS was applied in tracing the movement of moving picture in this research. By applying TSS, it was possible to calculate multiple motion vectors from moving picture, and then camera's motion parameters were obtained by utilizing the relationship between the motion vectors. For the purpose of experiencing the virtual reality by synchronizing the camera's accelerated velocity and the simulator's movements, the relationship between the value of camera's accelerated velocity and the simulator's movements was analyzed and its result was applied to the neutral network training. It has been proved that the proposed virtual reality immersion system in this dissertation can dynamically control the movements of moving picture and can also operate the simulator quite similarly to the real movements of moving picture.

In the Western and Oriental architecture, corridor and stairs have not been important from the whole architectural composition. The purpose of this study is to analyze their elements from theoretical viewpoint of modern architecture. The subject of analysis are Yangjindang and Daesanru of the Mid-Chosun Dynasty in Sangju. The conclusions are the followings : First, the moving line in the Western and Oriental architecture has the linear axis, and in general moving axis is straighten in Hanok architecture. But unlike common traditional architecture, the two buildings are right-angled in the moving axies. Second, Toenmaru in Yangjindang is the element of visual experience in the whole architectural space as promenade architecture called by Le Corbusier. On the other hand, Toenmaru in Daesanru plays a role the space of thinking in extending a visual field to the nature than its pure function. Third, the stairs of Yangjindang is diagonal shape with a role of entrance, but that of Daesanru was concealed in the wall as interior step. Yangjindang has two different stairs. One is broad and shallow stairs with ceremonial or public expression, and the other is narrow and steep stairs with unstable or private expression. This paper intends to show the latent architectural possibility of our traditional architecture.

Marine reactor systems experience platform movement, and therefore, the system thermal-hydraulic analysis code needs to reflect the motion effect on the fluid to evaluate reactor safety. A moving reactor model for MARS-KS was developed to simulate the hydrodynamic phenomena in the reactor under motion conditions; however, its applicability does not cover the MULTID component used in multidimensional flow analyses. In this study, a moving reactor model is implemented for the MULTID component to address the importance of multidimensional flow effects under dynamic motion. The concept of the volume connection is generalized to facilitate the handling of the junction of MULTID. Further, the accuracy in calculating the pressure head between volumes is enhanced to precisely evaluate the additional body force. Finally, the Coriolis force is modeled in the momentum equations in an acceleration form. The improvements are verified with conceptual problems; the modified model shows good agreement with the analytical solutions and the computational fluid dynamic (CFD) simulation results. Moreover, a simplified gravity-driven injection is simulated, and the model is validated against a ship flooding experiment. Throughout the verifications and validations, the model showed that the modification was well implemented to determine the capability of multidimensional flow analysis under ocean conditions.

In recent years, conoeptualizations of the residential crowding phenomena have developed form deterministic approaches to functionalistic ones which emphasize the interaction of environmental , social, and personal variables. The influences of each variables which are believed to mediate the crowding perception have been tested. This study examines the association of the influence of socio-demographic variables, residential setting and previous residential experience with the residential crowding. Futhermore, the residential adoptation behavior in response to the crowding phenomena is analyzed. The results of a survey are as follows; 1)The most important variables which influence residential crowding are the residential setting variables such as the floor space and the measure of persons per room. Also the household income and the family structure influence the residential crowding. No previous residential experience effects were found. 2)The residential adoptation behavior is influenced by sex, age and socio-economic status of the family. Female and the age group of 20s and 30s tend to prefer such alternatives as moving or residential alterations and additions. On the other hand, male and the age group of 40s and 50s tend to prefer staying without nay alternatives or structural family adoptation. The group of higher socio- economic status tend to show higher preference to moving and alterations, and the lower ones tend to stay or take the alternative of the structural family adoptation. Years of education and the family structure do not influence the residential adopation behavior.

The Affordance, discussed in the theory of ecological perception of environmental psychology, is the concept of perception that deals with inter-relationship between environment and human. It is a theory seeking for gradual evolution, with the change of user experience behavior and the space, by getting feed-backs from the analysis of perception of characteristics of 3-dimensional space and the user as moving entity. Although there has been many attempts to define the Affordance and apply its concept to the architecture, now there's a need to identify the Affordance in the real architectural space, represent Affordance of space and the user inter-relationship in the architecture and apply its design specifically, Thus, the purpose of this study is to present the methodology of applying Affordance in architectural space design by identifying the Affordance of space concept of human experience behavior in the architectural space and analyze its recognition process.

In order to determine whether foals of move dominant mothers were harassed less by mares than those of lower-ranked mothers, harassment of foals was studied in a herd of Jeju ponies (Equus caballus) consisting of 73 mares, their 53 foals, and one stallion. Mares Harassed the foals on 71 occasions between March to September,1998. The frequency of harassment tended to decrease as foals aged, but the relationship was not significant (P = 0.079). Foals were harassed when sleeping (n = 14), grazing (n = 19), moving (n = 8), approaching a mare in the vicinity (n = 13), or play-fighting with the foal of the harassing mare (n = 17). Mares harassed foals of younger, more subordinate mares than those of older, more dominant mares (P < 0.001). We conclude that early social experience of foals is associated with the dominance rank of its mother.
