The purpose of this study is to study how F.L. Wright reflected the climatic properties and materials of the region into creative ways of designing his architecture. The research method examined the design methods and use of materials by Wright in existing research literature and compares the space plans of housing works in Arizona. The research results will be summarized as follows : 1) For two-story houses, pilotis was used to avoid the hot air and the walls on the ground floor were often planned as thick wall. 2) In the fifties, F.L. Wright's design method changed in a circle from the vertical and horizontal lines. 3) F.L.Wright's Architectural form concepts and design concepts were extracted from local symbolic forms and natural forms. 4) F.L.Wright avoided Arizona's direct light but Indirect sunlight enters into the interior space. 5)External space was expressed as a closed space, while internal space was expressed as an open space. It's like an organic space. 6) Most of the housing materials used are stone and cement from rough deserts, and wood with low heat conductivity and thick concrete blocks to prevent the sunlight from rising above.

Purpose: Recently, a sudden increase in one household in Korea has become an important social problem. Changes in lifestyles such as population change, marriage, childbirth, and divorce are becoming increasing factors for single-family households. As a result of these changes, the government has implemented policies for one accredited state. However, the policy for one domestic applicant is insufficient compared to other countries. As a measure to cope with the increase in the number of applicants, Shared House has emerged and research on Shared House is necessary. Method: First, we analyze the overall characteristics of domestic share house. And it does a spatial analysis of domestic share house. Especially, it analyzes the relationship between private space and public space. Finally, the plan characteristics are derived based on the analysis results. Result: The results are as follows. First, the type of share house is classified according to the combination of the arrangement of private space and the public space. Second, the larger the scale, the more vertical arrangement than horizontal arrangement. Finally, the character of the share house changes according to the characteristics of the resident.

This paper is to investigate passing performance of high performance concrete between reinforcing bar depending on maximum size of coarse aggregates. Increase in maximum size of coarse results in decrease in water demand and sand to aggregate to secure target slump flow. The larger the maximum size of coarse aggregates is, the denser the space between reinforcing bar is, the amount of concrete passed through the reinforcing bar cage shows to decrease. HPC has favorable passing performance, regardless of aggregate size, when only vertical reinforcing bar is arranged. Whereas, when vertical and horizontal reinforcing bar is arranged at the same time, proper space between reinforcing bar is considered larger than 32mm in case of using 20mm coarse aggregate, 38mm in case of using 25mm aggregate. The increase in maximum size of coarse aggregate leads to increase compressive strength slightly. Length change shows to be decreased with the increase in maximum size of coarse aggregate.

Frank Lloyd Wright, a master of the 20th Century Ar-chitecture, contributed tremendously in creating a wholly new form of American architecture called Prairie Style. His idea behind the development of the building structur-al system, organic relationships between inner and outer space, horizontal vertical lines, and idea of extending and expanding interior spaces came from nature. He had completed over 390 projects throughout his life and 90% of those projects were residential design. The most typical characteristic shared by many of his residential design was that each design element, whether it is functional or aesthetical, has close relationship to or-ganic nature, human scale, theoretical floor plants, and maximum emphasis on horizontal lines in respect to na-ture. His concept of "flow of spaces" reformed common the-ory of room next to room in a enclosed space. His sense of "wall" was no longer the side of a box. Careful selec-tion of finishing materials, colors, and natural images en-hance the design as well. F.L. Wright was an artist, designer, and architect who believed the exterior space should have direct relationship to the interior space. His architectural philosophy was not only to design exterior of architecture but also to ful-fill his space through the careful development of interior elements such as furniture, and lighting fixture. Even the patterns for leaded glass windows were designed to have unified appearance from outside to inside of the house. The objective of this study was to analyze floor plans, spatial organizations, and interior design elements of the houses which represent the best of F.L. Wright's design principles and philosophy behind Prairie Style. The meth-od used to collect informations for this study was based on books, articles, journals, and actual site visits. actual site visits.

In this paper, we propose a new class of segmentation technique for feature extraction based on the statistical and regional classification at each vertical or horizontal line of digital image data. Data is processed and clustered at each line, different from the point or space process. They are designed to segment gray-scale sectional images using a horizontal and vertical line process due to their statistical and property differences, and to extract the feature. The techniques presented here show efficient results in case of the gray level overlap and not having threshold image. Such images are also not easy to be segmented by the global or local threshold methods. Line pixels inform us the sectionable data, and can be set according to cluster quality due to the differences of histogram and statistical data. The total segmentation on line clusters can be obtained by adaptive extension onto the horizontal axis. Each processed region has its own pixel value, resulting in feature extraction. The advantage and effectiveness of the line-cluster approach are both shown theoretically and demonstrated through the region-segmental carotid artery medical image processing.

Recently, as the number of high-rise building and earthquake occurrence are increasing, it is more important to consider horizontal load such as wind and seismic loads, earth pressure, for the pile foundation. Also, development of underground space in urban areas is more demanded to meet various problem induced by growing population. Many studies on pile subjected to horizontal load have been conducted by many researchers. However, research regarding interactive behavior on pile subjected to horizontal load with tunnel are rare, so far. In this study, therefore, study on the behaviors of ground and horizontal and vertical loads applied to single pile was carried out using laboratory model test and numerical analysis. The pile axial force and ground deformation were investigated according to offset between pile and tunnel (0.0D, 1.0D, 2.0D: D = tunnel diameter). At the same time, close range photogrammetry was used to measure displacement of underground due to tunnelling during laboratory model test. The results from numerical analysis were compared to that from laboratory model test.

Many Korean university campuses are located on hilly terrain where the hierarchy of the path system is unclear. Therefore, it is difficult to analyze the pedestrian network through space syntax, in which only horizontal direction changes are considered as depths of space. The purpose of this study is to compare pedestrian movement patterns and space syntax analysis in order to find their relevance to each other and the relationship between them. We conducted a survey regarding the most-visited buildings and pathways at S-University, which is located on a hilly area in Seoul. The survey results were compared with the Space Syntax integration map by regression analysis. For the segments where the relationship between pedestrian volume and integration was weak, field observations were conducted. As a result, topographical aspects, functional aspects, and location aspects were observed as the main influential factors. In addition, the research proposes that adding an extra axial line per vertical directional change can potentially compensate for the low relevance of stairs. This study suggests the possibility and the necessity of three-dimensional space syntax programs and emphasizes the importance of campus planning for the pedestrian environment.

Purpose: It seems obvious that the hospital structures become more large-sized and tall-risen in Korea today. Nothing is more influential than the vertical core plan on the movements of various people in such large-tall hospitals. The present paper, therefore, aims to study on the efficient hospital core space paying first attention to patients by analysing the data on relations between/among department layouts of vertical and horizontal movements. Methods: This study sampled representative 14 hospitals and drew their degrees of data importance on the basis of precedented relative studies. This study also analysed their placements on the blueprint and made confirmations of their arrangements through their homepage on line. Actual visits were made to make sure of the spacial connections between/among departments in the hospitals as well. Results: Even in emergency case in need for vertical movements, the central main core spaces are usually used, which is because special vertical transportation systems are not provided. In these cases, the main core spaces are very important for those who have to move vertically and/or horizontally according to the locations and types of main cores. While special lifts or dumbwaiters are prepared to install for the important articles, such as samples of pathology department, most patients should share with regular visitors the elevators not separated visually and spatially from them. Implications: Vertical core plans are greatly dependent on the ward types and hospital styles. This study is hopefully expected to contribute itself to the standard setting-up of comfortable and quick vertical core system operations for patients.

Focusing on the creation of a new han ok, especially a mid-rise hybrid-structured Han-ok, this study proposes a middle-rise (four-story) Han-ok on one and two lots located in Seoun-dong, the existing Han-ok intensive housing site in downtown Cheongju. 1) In terms of layout and function, according to the existing L-shaped Han-ok corresponding to the road and the direction, the parking lots and shops on the 1st floor, the business facility on the 2nd floor, the Han-ok on the 3rd and 4th floors are placed. There are yards, open roof yards, and semi-open Daecheong(大廳, main hall), which can be shared by residents. 2) In terms of structure and form, one or two floors (some 3 floors) are 5.4m square and 5.4×6.6m modules of the RC(Reinforced Concrete) group, and the upper floor reflects the 2.7m module, size and shape of the existing Han-ok. By extending the outer wall of the RC group in the lower floors (1st to 3rd floors) to the wooden exterior of the upper floors (2nd to 4th floors), it is attempted to avoid the awkward appearance of the RC group being exposed to wooden structures. And it is also attempted to reflect the wooden shape and design elements through the elevation elements such as horizontal windows, corner windows, picture frames, and vertical slits. 3) In environmental control and facilities, it is attempted to smooth the ventilation of the building by forming a vertical upward airflow from the dark space of the low floor to the positive of the upper floor. This doubles the effect through a vertical rise of cold air generated in a narrow alleyway, piloti parking lot, and the various voids. In addition to the Daecheong and Numaru(loft) of Han ok, the rooftop yard, the terrace, and the balcony, horizontal natural ventilation is generated through divided doors and transom windows.
