The aim of this study is to extract the design vocabulary of flexibility from analyzing Steven Holl' architectural works. For this purpose, the four works were selected and the design elements like their concepts, elevations, plans, furnitures, lights, materials, and colors were analyzed. The results of this study are as follows ; First, flexible design method is shown in adaptable space planning by using system of hinged panel and multi-functional furniture of various form. Second, Windows were made a plan of the geometric partition of surface and with clear materials for expanding space to outside. Third, the changing of level and the using of the phenomenological elements like a light color, water, and materials were applied for enhancing the image of the flexible space.

The real-time monitoring of surface vegetation is essential for the management of droughts, vegetation growth, and water resources. The availability of land cover maps based on remotely collected data makes the monitoring of surface vegetation easier. The vegetation index in an area is likely to be proportional to meteorological elements there such as air temperature and precipitation. This study investigated relationship between vegetation index based on Moderate Resolution Image Spectroradiometer (MODIS) and ground-measured meteorological elements at the Yongdam catchment station. To do this, 16-day averaged data were used. It was found that the vegetation index is well correlated to air temperature but poorly correlated to precipitation. The study provides some intuition and guidelines for the study of the droughts and ecologies in the future.

Concrete is a representative heterogeneous material and mechanical properties of concrete are influenced by various factors. Due to the fact that pores in concrete affect determining compressive strength of concrete, studies which deal with distribution and magnitudes of pores are very important. That way, studies using picture imaging have been emerged. Studies on mechanical performance evaluation of structural lightweight foamed concrete and FEM analysis based on picture image are inadequate because lightweight foamed concrete has been researched for only non-structural. Therefore, in this study, cement paste with foaming agent to evaluate mechanical performance is made, FEM analysis with picture image is conducted and young's modulus of experiment and analysis are compared. In this study, dosage of foaming agent is determined 7 level to check pore distribution and water-binder ratio is determined 20% to progress research about structural light weight foamed concrete. Weight of unit volume is minimum at 0.8% of foaming agent dosage. However, weight of unit volume is increased over 0.8% of foaming agent dosage because of interconnection with independent pores. For FEM analysis, cement paste is photographed to use image analyzer(HF-MA C01). Consequently, the fact that Young's Modulus of experiment and FEM analysis are same is drawn by using OOF(Object Oriented Finite elements).

This study aimed finding effective models for the teaching the concept of function. We selected two models. One is discrete model which focuses on the 'corresponding relation of the elements of the sets(domain and range). The other is continuous model which focuses on the dependent relationship of the two variables connected in variable phenomenon. A vending machine model was used as a discrete model, and a water bucket model was used as a continuous model in our study. We taught 2 times about the concept of function using two models to the 60 students (7th grade, 2 classes) living in Taebak city, and tested it twice, after class and about 3 months later. A vending machine model was helpful in understanding the definition of function in the 7th grade math textbook. Also, it was helpful to making concept image and to recalling it. On the other hand, students who used the water bucket model had a difficultly in understanding the all independent variables of the domain corresponding to the dependent variables. But they excelled in tasks making formula expression and understanding changing situations.

The tendency of formalization in Contemporary Architecture deeply relies on the thought of Western Philosophy, which emphasizes the art of image perceived visually but ignores the body and perception of a human beig who uses the architecture and lives in it. On the contrary, Merleau-Ponty asserted long time ago that the world and the body are inseparably related to each other. The phenomenology is important in Architecture, since the center of thought should be taken back to the human body if a artistic meaning can be obtained by Architecture. From this point of view, the meaning of Contemporary Architecture can be renewed by the phenomenological idea of Merleau-Ponty as a means of expanding thought that overcomes the limit of formalization in Contemporary Architecture. This research aims to ream from Steven Holl's work, and show the Architectural elements that are used for preceptual experience of phenomenon and the function of those element sin Architectural space of his works. The result of study on about the phenomenal light and water in Architectural space of Steven Holl is as follows; First, in perceptional experience of phenomenon, time is an important element, which is successive and make a field that cause perceptional experience. Second, light, as a phenomenological element, acted as a means of expressing the comparison and change of light and shadow in Architectural space and showing the change of color by the diversity of time in inner space. Third, water, as a phenomenal lens, not only acted functional but also functioned as an element of sensual experience in Architectural space. It acted as an image containing time, space, just like a mirror that reflect the environment.

The purpose of this study is to introduce the design process for the 'natural-friendly' kindergarten playground using participatory design method. The 'A' kindergarten in Daejon was selected as a case study. The concept of the design was decided by the user's needs which draw out the pictures of children, owner's educational philosophy, and request of the teachers. As a result, the concept approached to 'our neighborhood (Korean traditional village)' image, and was planned with a focus on open space, which allows rich in natural elements(earth ground, trees, flowers vegetable farm, animals, water and sand etc.) and various play activities. And a user participatory design method proved that it was proper to design a kindergarten playground.

Urban watershed can be found in the visible changes in technology, the most realistic satellite images is to use the data. Satellite image data on the indicators for progress on the nature of the change of land use is consistent and repetitive information, regular observation makes possible the detailed analysis of space-time. These remote sensing techniques and the type of course and, by using the time series history, the past, the dynamic model and the randomized prediction methodology for the conversion process if the city and river basin cooperation of the space changes effectively will be able to extrapolate. For each of the main changes in river flow, depending on the area of urbanization as determined according to reproduce the duration of the relationship between the urbanization of the area and runoff can be represented as a linear polynomial expression was, if a linear expression in the two fast slew rate of 0.858 to 0.861 showed up, and fast slew rate of 0.934 to 0.974 for the polynomial are reported. Change of land use changes in the watershed of the flow is one of the most affecting elements. Therefore, changes in land use of the correct classification of rivers is a more accurate calculation of the amount of the floodgate. In particular, using the Landsat images through the image of the land use category, land use past data and calculated using the Markov Chain model and predict the future land use plan in the water control project will be used for large likely.

Commercial space, the types of which have been increasingly various and changing rapidly, has been generating new marketing concepts for space. Especially as the environmentally friendly lifestyle spreads around, the component of natural landscape such as plant, stone, or water has been used as an important part in space design, freshly imprinting the brand image beyond the idea of simple interior property. By combining commercial space design with 'the component of the natural landscape', we can improve the brand image, create the newness in the space, lead customers to stay longer in the space, and reinforce the decorative effect. The parts of the commercial space to which we can apply the element of natural landscape are facades, walls, floors, and show windows. Various examples of real application are found according to the areas of business and goods displayed. This thesis attempts to maximize the effect of commercial space by examining and analyzing various instances of space and provide the ways of applying the space that contains an aesthetic value. For the research, 60 articles, theses, reports that have the keyword related to interior landscape and marketing strategy in commercial space were used as references. From the references, 70 cases were selected and analyzed to find landscape application patterns. Also, 4 store cases that landscape application have been the key to their success were selected for the survey. In doing this, I presented the readers with the packaging technique which improves brand image, the effect of stage direction which helps sensitive communication with users, the application as interior structure and the effect of an object that is useful to aesthetic effect in the commercial space. Finally, I endeavored to provide possible problems to be produced when applying the natural element in the commercial space and matters to be attended to in the management.

The Sitting Buddha Carved on Rockcliff (National treasure No. 201) in Bukjiri consists of porphyritic biotite granite, which was fractured by three joint sets of NE-SW, EW and NS directions. They produced a physical weathering that broke many parts of the Buddha and background. The chemical index of alteration is 59 to 61 from the major elements in the granite that was weathered into producing kaolin minerals from alteration of feldspars and biotite. With weathering degree, major element compositions increase in $SiO_2$ and MnO, whereas decrease in $TiO_2,\;{Fe_2O_3}^t,\;MgO,\;CaO\;and\;K_2O$. Change proporations of trace elements to $Al_2O_3$ increase in all transition elements, Rb and Y, whereas decrease in Li, Sr and Ba. REE pattern increases only in HREE. Particularly, a decrease in CaO, $K_2O$, Sr and Ba results in what they are effluxed to dissolve from feldspars by groundwater. The Buddha image has been deteriorated into joints, color changes, brown rusts, granular decay, microorganic smears by the such weathering causes as deformation, moisture, temperature variation and microorganic living. The moisture, which leaks along the joints in the granite, not only dissolve to decompose minerals but also grows many microorganism and is frozen over during winter. NE-SW and NS joint sets affect to seep in water during rainy days to deteriorate the image because they extend outward.
