Luis Barragan's Architecture has creative feature that Mexican environment and traditional culture were complete by color. Thus the color of his work makes our emotions rich and colorful. He said "My architecture is autobiographical..." at speech in Pritz price. As we can see in his architectural philosophy that sentimental architecture is important than theorical system, his works are impression of empirical factor with intuition. "Color is a complement to the architecture. It serve to enlarge or reduce a space. It's also useful for adding that touch of magic a place needs", stated Barragan. During his process of shaping space, Barragan drew on color in the same way as an architectural component, according it a spatial funtion and expressive vale. he allied it with light, deeming it a crucial vehical for conveying the emotive attributes a site. The capacity of color to express sensitivity and sensuality within an architecture space is liked to its psycho-physiological qualities. In this kind of view, color featyre in Barragan's work is one of the most important tools to realize sentimental architecture, not only is result of the Mexican regional color. As a result, make focus on analyzing various meaning of the color in Barragan's architecture like poetic and habitable structure.

Many researches on the typology of 'Maru' (Wooden deck) in Korean traditional houses have mainly focused on the high-class houses in the central region of Korea. They were mainly concerned on defining Maru's typology by social status of the owner, based on the researches regarding its physical and spatial properties. Maru in the high-class traditional houses has been served as an essential architectural feature showing the social status of owners as well as adapting in the region of humid and hot summer. This research investigated the typology of Maru's placement in traditional single houses of four Kan in Chonnam province, which shows many differences in its placement according to the regions. Research results show that the typology of Maru's placement and openness is different with the location of houses within the region. This difference affects on the circulation of movement, which eventually affects on the pattern of space use. The difference is also very likely to be affected by the natural environment of geography and climate of the region.

Freak waves in the ocean are recently drawing much attention as a natural disaster to ocean structures and navigating ships as well. Several observation data, among them the Draupner New Year Wave, show the very impressive feature of Freak waves whose wave height is up to three times as high as the significant wave height of surrounding waves, In addition, Freak wave appears as an isolated very high crest in somewhat stationary random waves of same order in their wavelengths. Bearing such characteristics in mind, one notices its extraordinary steepness. This strongly suggests that Freak wave is not long lived but transient nature on the whole. A great number of studies to explain these natures were published from both theoretical and numerical point of view. However it is not sure if they are applicable to actual ocean environment. In this paper, we deal with the results concerning abnormal and/or Freak waves from in-situ ocean wave data and point out several remarks to the problems lain behind the contributions in this context. A physical experiment is described to reinforce the subject discussed from the observation data.

From the research which sees the building which uses a natural control method with ecological architecture, continuity tried to divide the building which uses a physical control method with sustainable architecture. Ecological architecture analyzes the microclimate of the area and applies mining and natural ventilation leads and that the interior environment controls, the condition of the site actively and there is a possibility of seeing. Also sustainable architecture which is possible to lead and recycling and reuse of the resources and energy cyclic process of the construction resources to lead and the interior environment to control. Therefore the case where the facility system and structural system become integrated design organically in natural circulating method is many. Specially the sunshade system and double skin system are combined and structural system of the building and there is a possibility of having the envelope which form is feature. Today the buildings lead and the system integration process where the integral parts are systematic is demanded the interior environment which and an external form and that, they make they are there is a possibility of seeing. the environmental building which hits joins in with natural control method and the structure and facility system are integrated and has the tendency which is developed and there is a possibility of saying that a meaning with the alternative construction will be able to reduce the resources and an energy.

Piston friction is one of the important but complicated sources of energy loss of a hydraulic axial piston machine. In this paper, two formulas are derived for estimating instantaneous piston friction force and average piston friction moment loss. The derived formula can be applicable for piston guides with or without bushing as well as for axial piston machines of motoring and pumping operations. Through the formula derivation, a typical curve shape of friction force found from several experimental measurements during one revolution of a machine is clearly explained in this paper that it is mainly due to the equivalent friction coefficient dependent on its angular position. Stribeck curve effect can easily be incorporated into the formula by replacing outer and inner friction coefficients at both edges of a piston with the coefficient given by Manring (1999) considering mixed/boundary lubrication effects. Novel feature of the derived formula is that it is represented only by physical dimensions of a machine, hence it allows to estimate the piston friction force and loss moment of a machine without hardworking experimental test.

Stress adversely affects the wellbeing of commercial chickens, and comes with an economic cost to the industry that cannot be ignored. In this paper, we first develop an inexpensive and non-invasive, automatic online-monitoring prototype that uses sound data to notify producers of a stressful situation in a commercial poultry facility. The proposed system is structured hierarchically with three binary-classifier support vector machines. First, it selects an optimal acoustic feature subset from the sound emitted by the laying hens. The detection and classification module detects the stress from changes in the sound and classifies it into subsidiary sound types, such as physical stress from changes in temperature, and mental stress from fear. Finally, an experimental evaluation was performed using real sound data from an audio-surveillance system. The accuracy in detecting stress approached 96.2%, and the classification model was validated, confirming that the average classification accuracy was 96.7%, and that its recall and precision measures were satisfactory.

The purpose of this study is to grasp the change of modern space concept and analyze how to adopt and embody the change in modern fashion. The study researched wearer's costume space and analyzed space shown in supermodern fashion design by classifying it into response to non-space, allowance of wearer-based space, scientific space of architectural skill and embodiment of space image. As a study method, literature and study material of sociology, anthropology, fashion sociology and design field were referred. For picture data of supermodern fashion work, specialized book, designer, brand collection material and internet site pictures were collected and analyzed. The study result shows the following features of fashion design space embodiment corresponding to the change of supermodern environment. First, supermodern design secures closet space like pocket for portable objects and uses design space in order to provide the space for convenience of movement. Second, supermodern design creates wearer-based independent space in order to secure person's physical and mental stability in city environment. Third, supermodern design uses space scientifically from the aspect of detail and shape by applying space of architectural skill to space. Fourth, supermodern design shows aesthetic feature that embodies interpretation of space by conceptualizing space image and using fashion.

The purpose of this study is to analyze the document delivery service(DDS) of the academic libraries and suggest its improvement model in Korea. DDS means providing copies of information requests in any format and from any source. And DDS is gaining in importance as libraries turn to 'just-in-time' access rather than 'just-in-case' collection to meet user information needs. By good fortune, rising journal subscription prices, declining financial resources, canceling some of journal subscriptions, electronic transmission technologies, and the rise of commercial document delivery services have allowed libraries to begin to deliver articles to users in a much more rapid and acceptable time frame. Therefore, the library paradigm for the 2000s must be the creation of new document delivery structures which capitalize on the access tolls and structures created by librarians during the past generations. First of all, library-based document service requires a close review of existing library-to-library delivery mechanisms, application of technology to transfer of facsimiles of materials and facilitated use of existing fee-based document sources. The ideal document delivery system would feature a transparent, seamless electronic service incorporating searching and browsing identification and marking of desired items, and transmission and fulfillment of requests. And requested items would be supplied from library collection, commercial suppliers, or other sources. But the future of DDS will succeed when physical resources, policies, personnel, and practices are organized to provide timely information delivery to users.

The first objective of this study is to investigate and analyze the construction of TUTU and secondly, to propose a systematic research background on a sewing method of TUTU. The final objective is to provide the exquisiteness and the comfort for customer when wearing a stage costume. The research method to investigate the TUTU construction in detail is by renting or buying three major TUTU brands, which are selling in Korea. The results of this study can be summarized into four categories. Firstly, the Bustier composes into 8 to10 patches, and the external material or accessory differs by the work of art and its characteristics. Moreover, the cotton is used for the inner material. which depends on dancer's vital activities. Secondly, a skirt layer ranges from 6 to 12 layers with laces. In addition, the gather or the pleats is used to form a crease. Thirdly, lace or cotton is the material used for culottes because it is stretchy and lightweight. For the waist part. a rubber band is used since its wearability plus functionality. Lastly, an adjusting part for a stage costume varied for each dressers physical feature and can be corrected with inner hems together a hook, a thread loop or a zip. In conclusion, the results of this study can provide the quality improvement for TUTU and furthermore can propose a framework for an understanding and a practical use of TUTU construction.
