This paper features about the modeling and design of a fast output sampling feedback controller for a smart Timoshenko beam system for a SISO case by considering the first 3 vibratory modes. The beam structure is modeled in state space form using FEM technique and the Timoshenko beam theory by dividing the beam into 4 finite elements and placing the piezoelectric sensor/actuator at one location as a collocated pair, i.e., as surface mounted sensor/actuator, say, at FE position 2. State space models are developed for various aspect ratios by considering the shear effects and the axial displacements. The effects of changing the aspect ratio on the master structure is observed and the performance of the designed FOS controller on the beam system is evaluated for vibration control.

This study is to present the visual phenomenon of natural light in the interior space. The continuously changing natural light define the visual phenomenon of the architectural space. First, the objective of this study was finding the importance of the visual phenomena which were generated from correlating natural right with the interior space. And the second was to categorize the factors of the visual phenomenon which can be useful factors for modern interior design practice. As a result of this study, two visual phenomena were classified. First; territorial phenomenon: dividing, partitioning, and sectioning by natural light, Second; phenomena by the inflow methods of natural light; a) by direct inflow; transparency, expansion, and floating, b) by filtering fixtures; the architectural structure, color, and the transluscent material, c) by dramatic spacial present of natural light, d) by the sense of direction of naturel light; continuity, and transformatiov. Found and classified each factor is not presented by itself, rather compounded forms. Because of the limited analysis of modern buildings, these found visual factors can not represent all phenomena. But if we practice these finding factors to design present interior space, it is sure of being very valuable factors to re-introduce the overlooked natural light into interior space.

This study focuses on analyzing children's behavior from an integrated systemic perspective of the space and time and presenting a criterion and a guide of children-centered environmental color for intensifying their behavior affordance while considering functions of the space and color. Research was conducted as follows. Based on the spatial function and children's behavior, it figured out a prerequisite of educational environmental colors for behavior affordance. It extracted colors by dividing children's behavior affordance into 8elements considering a psychology of expectation and color function according to spatial and behavior affordance intensification elements. So 97school colors were selected for children's behavior affordance from abstracted colors by each element. Furthermore, it planned to suggest an environmental color guide for establishing elementary school's positive educational circumstances through enhancing behavior affordance, providing a potential to change a color environment at the educational space.

The construction can proceed in different ways according to the acquired profitability of the hospital during the construction and to the features of departments or areas. This study is an analysis of remodeling construction processes to resolve major tasks of remodeling. The remodeling strategies gained from this study can be summed up as follows: 1) Remodeling work in hospitals involves the acquire relocation of space through extensive area renovations and then moving back to the space, and lastly working on the empty space. Thus, it is more advantageous in terms of construction work to demolish the existing buildings than to acquire the relocation space through extensions or renovations. That is, demolition after the maximum utilization of the existing buildings is the most desirable in terms of space availability. 2) The construction methods for remodeling are two: a method of carrying out construction by dividing the plane areas into several individual ones and of working on it floor by floor. In case of ward areas, and the outpatient area, the construction proceeds after securing the relocation space and partially setting construction areas in order to minimize the decrease in profitability due to the smaller number of beds and treatment rooms during construction. If the outpatient diagnosis/ treatment area and the supply area relocate together with the ward areas, there may be extra expenses. Thus, doing construction by area, while partially operating those areas or after relocating the whole areas.

This study was intended to grasp the research trends related to the spatial composition of nursing homes. The 43 research papers were collected and analyzed. They were analyzed to focus on the research methodology and research contents related to the spatial composition of nursing home. The researches on spatial composition of nursing home were categorized into 5 types ; 1) the researches on the overall spatial composition of nursing homes, 2) the ones on space planning of each room in nursing homes, 3) the ones on the space size of nursing home, 4) the ones on the spatial composition of nursing homes in foreign countries, 5) the ones on the usage conversion of small-sized hospital and closed school into nursing home. The size and layout of a bedroom and common space were the main issue. These studies have been consistently carried out since late 1990 and many researches used the method of the analysis of floor plan and the field study. However, the number of the subject nursing homes and the categorized space areas were different depending on studies. Therefore, it was difficult to synthesize these various results. In order to compare and synthesizing the various results of these many studies, the same criteria for dividing the spaces of nursing home needs to be applied. However, many results from these researches related to the space composition of nursing home would be the useful data for planning the nursing home.

Architectural color would be understood as a essential tool to be reflected the architect's value criteria, thinking process and the specific methodology. This study was established the characteristics of color use correlated with Eisenman's architectural features based on his point of view. At first, it could be organized with data and use the color in view points with the becomming process. Especially it would be expressed the color as a trace of unsynchronized formation. Second, it was introduced the color by graphics engaged with form, to be expressed the dividing, folding, reiteration for deliver of escape from graphic thinking process. Third, it was analyzed to be imported the color to have a multi-lateral space experience in center of user's space recognition and behavior by introduction of color. Finally, it could be inducted the consistent color by viewpoint of interfacial between interior and exterior environment, communicated with strong meaning by conversion from interior elements to color from these processes. A characteristics of Eisenman's architecture color is reflected his thinking process in architecture color as it is and can be understand of 'becomming process use of color' as a tool that is corresponded in form creation. Specially, it would be kept continuous viewpoint of interior and exterior space, giving user color as a viewpoint of linking space, enable many-sidedness experiences through space.

Visitors' behaviors within an exhibition space are a substantial means to grant spatial arrangement and validity of exhibits. Therefore, the study analyzed visitors' behaviors in the viewpoint of attraction power and holding power of exhibits on the basis of exhibition layout of real science museums. Through the analysis, the study grasped efficiency of analysis index and exhibition environment elements which might have an effect on planning the exhibition space of a large-scale museum and producing detailed ranges of exhibition. The main indicators used are: 1. Attraction power: it indicates the relative incidence of people who have stopped in front of an object/exhibit during the exhibition tour. It is calculated by dividing the number of people who stop by the total number of people who have visited the museum or gallery. 2. Holding power: it measures the average time spent in front of an information/communication element. It is calculated by dividing the average time of stay by the time "necessary" to read an element. As a result, It was expected that attraction power and holding power of exhibit would be increased when moving line of seeing was inductive. However, when the traffic movements of seeing was inductive, repetitive seeing of exhibit was almost never realized and visitors had a strong tendency which viewed on their way of moving without viewing on their way of stopping. On the other hand, it may mean that density of exhibit is low or size of exhibition space is small that most of exhibits within exhibition space have high attraction power and holding power. As Gwacheon National Science Museum, when a museum is composed of many large-scale exhibit halls, it should be formed by separating the main moving line of seeing from the optional moving line of seeing through visitors' natural choice of exhibit and proper inducement of moving line of seeing. In such structure, exhibition environment of the main moving line has an effect on attraction of exhibit and the use of optional moving line acts as a factor to increase attraction. In addition, it is thought that attribute of exhibit and proper arrangement of rest space within exhibition space will increase holding power of exhibit.

As the quality of life has improved today, there is a growing desire among consumers for new space and interest in spending their valuable time in 'the third space' has tended to increase. Cafes have been integrated with sales and exhibition space as the representative third space. For example, it's cafe type automobile exhibition centers. The purpose of this study is to examine the characteristics of 'the third space' in cafe type automobile exhibition centers and suggest a plan for effective spatial characteristics. It checked the necessity of the third space' in automobile exhibition centers by analyzing automobile consumption trends of the 21st century according to industry change and restructures a checklist by grasping cafe type automobile exhibition centers and the concept and characteristics of 'the third space' based on the precedent studies. A questionnaire is made through the checklist drawn and a survey is conducted targeting users of the target areas of cases. The target areas of cases are 4 cafe type automobile exhibition centers opened in Korea since 2014. The analytical results of the target areas of cases that reflected the characteristics of 'the third space' are as follow: First, cafe type automobile exhibition centers must be built to make customers enter the space and at the same time, receive information on automobiles and space naturally. Second, in order to increase satisfaction with the space and brands, there is the necessity to arouse their interest through various experiences including test driving cars directly. Third, revisit intention can be found to be more influenced by spatial design than brand satisfaction. Fourth, partitions or interior for dividing the space need to be improved. In the next studies, specific research on plans about creating design to improve corporate image and brands and induce customers to revisit cafe type automobile exhibition centers by applying the characteristics of 'the third place' to them is required.
