This study aims to understand functional spaces within university dormitory, examine the influences of residential environment factors and personal characteristics on users' satisfaction through what parameters and probability among these parameters and seek improvement methods for dormitory users to live at dormitory as the best residential space through causal analysis of residential space uses at university dormitory based on such a probability. Research methods include theoretical research of architectural space characteristics of university dormitory facilities through literature survey, analysis of satisfaction with spaces and their uses through questionnaire and causal analysis of each residential environment factor after making route model using data obtained from the results of analysis. The results of this study are as follows. Factors affecting residents' satisfaction with cultural activities of residential environment factors are safety, territoriality, interior finishing and complexity and those affecting residents' educational activities are safety and amenity of space. Residential function space of university dormitory must have spatial planning that social activities including individual and small group culture and educational activities from the view of spatial territoriality and flexibility based on safety and amenity and facilities related to continuity and connection of common space and unit residential space should be decentralized rather than centralized.

This study is to find a way that improves the pedestrian environment in the main street in rural areas. The main streets of five local governments in Jeollanam-do, general towns and bases seat of a myeon office, were studied. The research results are as follows. First, all three groups under investigation required multi-purpose activities on main street. This is thought to be due to the maintenance of the main street with vehicle-centered maintenance, thereby revising the walking space around essential activities. Second, the simple size of the sidewalk width is not closely related to the safety of pedestrians, and it is judged that the pedestrian space should be maintained considering the size of the floating population, acceptable activities, and proper sidewalk width. Third, the center where pedestrian space and streetscape are maintained has spatial constraints on sidewalks and lanes, so there should be spatial flexibility. Also, it is necessary to find a way to minimize the occupancy of pedestrian roads due to ground parking lots in relation to pedestrian continuity. Fourth, improvement of walking environment should involve community activities other than physical improvement.

This paper is a research about the expression and characteristics of sense space by a phenomenological approach through body from an anthropocentric point of view. The phenomenological expression elements of sense space have been abstracted by putting the characteristics of body perception into shape through the phenomenological approach. This research aims to provide the expression and characteristics of sense space that can be applied by phenomenological elements of emotional expression, and analyze their application level by phenomenological body perception in space through corresponding examples. As a result of this research, the expressions of sense space approach - such as migration of moving lines, reiteration and segmentation of region, spatial flexibility, transferal of sense, stimulation of combined senses, symbolic abstraction of memory, perception of environment and space, time by light, phenomenal water space, time expression by surrounding environments etc. - and the characteristics of sense space according to each expression have been obtained through the phenomenological expression elements in sense space such as expansive perception by consecutive scenes, spatial and sensory experience, embodiment of place, phenomenal change by time. It aims to grope for a new approach and possibility to the embodiment and expression of sense space through the expression of sense space approach based on the phenomenological body perception.

Particle image velocimetry(PIV), a planar measuring technique, is an efficient tool for studying the complicated flow field such as in-cylinder flow, and intake port flow. PIV can be also used for analyzing the integral length scale of turbulence, which is a measure of the size of the large eddies that contain most of the turbulence kinetic energy. In this study, dual color scanning PIV was designed and demonstrated by using a rotating mirror and a beam splitter. This PIV system allowed enlargement of flexibility in the intensity of vectors to be calculated by spatial filtering technique, even in combustion chamber with high velocity gradient and high vorticity$({\sim}1000s^{-1})$. A new color image processing algorithm was developed, which was used to find the direction of particle movement directly from the digital image. These measuring techniques were successfully applied to obtaining the turbulence intensity (~0.1m/s) and the turbulent integral length scale of vorticity(~1mm).

Cable network system is a flexible lightweight structure which curved cables can transmit only tensile forces. The weight of cable roof dramatically can reduce when the length becomes large. The cable network system is too flexible, most cable systems are stabilized by pretension forces. The tensile force of cable system is greatly influenced by the sag ratio and pretension forces. Determining initial sag ratio of cable roof system is essential in a design process of cable structures. Final sag ratio and pretension depends on initial installed sag and on proper handling during installation. The design shape of cable system has an affect on the sag and pretension, and must be determined using well-defined design philosophy. This paper is carried out the comparative data of the deflection and tensile forces on the geometric non-linear analysis of cable network systems according to sag ratio. The study of cable network system is provided to technical informations for the design of a large span cable roof, analytical results are compared with the results of other researchers. Structural nonlinear analysis of systems having cable elements is relatively complex than other rigid structural systems because displacements are large as a reason of flexibility, initial prestress is applied to cables in order to increase the rigidity, and then divergence of nonlinear analysis occurs rather frequently. Therefore, cable network systems do not exhibit a typical nonlinear behavior, iterative method that can handle geometric nonlinearities are necessary.

This study aims to analyze the spatial characteristics of a group of samurai residences among other traditional Japanese villages and to accumulate the village-level sample data of a residential group, which can serve as the foundation for a wide range of discussions. Using data that had been gathered since 1989, this study draw up a prototype floor plans to analyze the indoor spatial features of the residences in the modern period, and sampled 35 samurai houses. The following are the results of this study. The general characteristics of traditional Japanese houses were found among many Izumi Fumoto samurai residences up until the early Meiji period. However, after gradually the floor plan became more and more simplified; connections between rooms were reduced, decreasing their flexibility; and there was a rise in the number of houses with a larger area devoted to the Nando, a room for women and family members. The access of a visitor involved changes in one's eye-level view and established physical and psychological boundaries, which this study conjectures was used as a method to ensure that the visitor recognized the authority of the patriarch and to raise the family's reputation. As their floor plan was simplified, Izumi Fumoto samurai houses established one's eye view, boundaries, and procedures as a way to enhance the authority of the man of the family and the family's reputation. In addition, while there was an increasing number of residences that expanded the area of the Nando, in which family members slept and used the space in a stable way, they maintained the exclusivity of private space and did not clearly show who would use it.

The main objective of this paper is to investigate the potential utility of multisensor remotely sensed data for improved coastal wetland mapping. Five data fusion models, three algebraic models (Multiplicative (MT), Brovey (BT) and Wavelet transform (WT)) and two spectral domain models (Principals component transform (PCT) and Intensity-Hue-Saturation (IHS)) were implemented and tested over the multisensor data. The fused images were then compared based on visual and statistical approaches. The results show that the wavelet transform provides greater flexibility for combining optical data sets and has good potential for preserving the spatial and spectral content of the original images . However, this model yields poor information when combining optical and microwave data. Brovey transform is more reliable for fusing optical and microwave image data and yields improved information about different wetland features of the coastal zone.
