The use of drones and laser scanners have the potential to drastically reduce the time and costs of conventional techniques employed for field survey of cultural heritage buildings. Moreover, point cloud data can be utilized to create an as-built Building Information Model (BIM), providing a repository for consistent operations information. However, BIM creation is not a requisite for heritage buildings, and their technological possibilities and barriers have not been documented. This research explored the processes required to convert a heritage university building to a BIM model, using existing off-the-shelf software applications. Point cloud data was gathered from drones for the exterior, while a laser scanner was employed for the interior of the building. The point clouds were preprocessed and used as references for the geometry of the building elements, including walls, slabs, windows, doors, and staircases. The BIM model was subsequently created for the individual elements using existing and custom libraries. The model was used to extract 2D CAD drawings that met the requirements of Korea's heritage preservation specifications. The experiment showed that technical improvements were needed to overcome issues of occlusion, modeling errors due to modeler's subjective judgements and point cloud data cleaning and filtering techniques.

In this study, existential thoughts in Frank Lloyd Wright's notion of nature were investigated. Wright, a modern architect, presented the idea of creating organic architecture in harmony with nature. His naturalistic romanticism is considered to be the original inspiration for his concept of organic architecture. However, his understanding of architecture in harmony with nature stems from existential ideas in his notion of nature, including humanity. The proposed study analyzes his existential beliefs through his speeches and writings in four categories-love of nature, thoughts of abstract and concrete, nature as being intrinsic and "becoming," and thoughts on science and art. Our analyses reveal that, on the one hand, Wright was inspired by thoughts of naturalistic romanticism born from his disillusionment with city life and an urge to seek life in nature, while, on the other, he also believed that real nature is intrinsic to humans and manifests itself in the very core of their being. He sought to unite humanity, as the interior of nature, with its physical environment, as the exterior of nature. His notion of nature is a "becoming" one that changes with time and space, and varies based on individual humans. In line with these thoughts, Wright sought to create forms not only with respect to mathematical dimensions, but also in consideration of human significance. He considered art and architecture to be born out of an integral thought as a process of humanization. To him, nature is interpreted by humans.

This study identifies the current status of hanok design process and required design information through individual survey and interview with hanok architects and builders to suggest a proposal. Current design system turns out to be a common design process not reflecting hanok's unique mechanism of production. The proposal consists of the alternative design process, 'Initial survey / Site and structural planning / Spatial layout and form / Openings, interior and exterior elements design / Detail design', containing the specialty of hanok's mechanism, and the lists of design information required in its each stage. The proposed design process also emphasizes the significance of consultation in a way of designing coordination, and classifies the specific contents for each consultation moments. The study is expected to contribute for architects including the group who are not specialized in hanok to improve the architectural quality by following the systematic design process. Also the design system provides a framework to organize the vast range of design information being recently developed in the technique-oriented area.

This study is to trace the change of stream shape using the past series of aerial photographs, and to compare the land use changes of riparian area along the stream. For the Gyeongan national stream, aerial photographs of 1966, 1981 and 2000 were selected and ortho-photographs were made with interior orientation and exterior orientation, respectively. Apparent changes of the stream were found that the consolidated reaches of stream by levee construction became straight together with widening of their stream widths. Especially the stream width of inlet part of Paldang lake widened almost twice because of the rise of water level by dam construction in 1974. The land use of riparian areas of three selected years were classified into six categories (water, forest, agricultural land, urban area, road, sandbar) by digitizing method. The forest and agricultural lands decreased and urban area increased as the stream maintenance had been performed.

The present paper investigates the simultaneous resonance behavior of spiral stiffened multilayer functionally graded (SSMFG) cylindrical shells with internal and external functionally graded stiffeners under the two-term large amplitude excitations. The structure is embedded within a generalized nonlinear viscoelastic foundation which is composed of a two-parameter Winkler-Pasternak foundation augmented by a Kelvin-Voigt viscoelastic model with a nonlinear cubic stiffness. The cylindrical shell has three layers consist of ceramic, FGM, and metal. The exterior layer of the cylindrical shell is rich ceramic while the interior layer is rich metal and the functionally graded material layer is located between these layers. With regard to classical shells theory, von-Kármán equation, and Hook law, the relations of stress-strain are derived for shell and stiffeners. The spiral stiffeners of the cylindrical shell are modeled according to the smeared stiffener technique. According to the Galerkin method, the discretized motion equation is obtained. The simultaneous resonance is obtained using the multiple scales method. Finally, the influences of different material and geometrical parameters on the system resonances are investigated comprehensively.

In this paper, the relationships between volumetric mixing ratio of rubber chip and physical and mechanical properties of wood/rubber composite panel was examined in order to investigate the mixture characteristics of wood and rubber chip. Because of the specific gravity of rubber differed from wood chip, physical properties of wood/rubber composite panel was shown very different values by mixing rate of chip element. Specific gravity in air-dry of composite panel was increased rapidly as volumetric percent of rubber chip was increased. Moisture content of composite panel was decreased as volumetric percent of rubber chip element was increased. This results was considered that wood weight is light and porosity material for moisture absorption. Compressive strength and modulus of rupture in bending test were decreased as volumetric percent of rubber chip increased. By mixing ratio control of chip elements, various wood/rubber composite panel can be applicable to every interior materials such as subfloor, playground, and exterior materials such as road blocks for recreational facilities in garden and forest and city parks.

A Culture is not the fashion that can be changed and created lightly. However, a small number of people are creating and leading the fashion for the foundation of a culture. For example, the fashion in Tokyo spreads across the nation, the fashion in Europe, USA and all over the world are under the influence of Paris, California and New York. Now, we should think about - what is the our consideration to be a member of the minority? What is the today's trend and how will be the future environment of interior, exterior and furniture design? Which one is the measure of the value for leading the culture? The answers in the design area are the creating new value and health in various design styles - Minimal, Organic, Multiple, Natural, Intelligent Life Style. Also this analysis of these trend should be more necessary for the space and environment design area of future than the furniture design area.

Lee Je Ma (1837~1900) wrote the DongEuSuSeBoWon in 1894. Constitutional Medicine what is called Sasang Medicine has originated from him. In this book he refers to mild, serious, intractable, incurable and fatal disease. In the sight of his Medical theory each state of disease deserves to be researched. 1. In the case of Soumin exhaustion of Yang, Taeyang-Kwolum, noxious Yin, Yang is kept in the exterior by excessive Yin in the interior, middle diabetes and swelling belong to intractable disease and solid mass in the right epigastric zone belongs to fatal disease. 2. In the case of Soyangin exhaustion of Yin, lower diabetes, afternoon fever due to deficiency of Yin, spitting blood and swelling belong to intractable disease and distention of abdomen with gas or fluid belongs to fatal disease. 3. In the case of Taeumin syncope due to chills, dryness-heat, diabetes, pain of chest and abdomen and swelling belong to intractable disease and apoplexy with dosed eyes belongs to fatal disease. 4. In the case of Taeyangin vertebral disease makes flaccidity of lower limbs and dysphagia with vomiting of frothy fluid belongs to fatal disease.

1. Objectives This paper was written in order to understand prescription's combination of Taeumin. 2. Methods We analysis prescription's combination of Taeumin through pathology and new prescription in Sinchukbon(辛丑本) of ${\ulcorner}$Dongyisusebowon${\lrcorner}$. 3. Results and Conclusions New prescription of Taeumin is combined with a few specific prescription. We analysis new prescription of the exterior disease and get the basic prescription that is Chobonkwon Taeummahwang-tang(太陰麻黃湯), Chobonkwon Saengmac-san(生脈散) and Gunyul ${\cdot}$ Euiin ${\cdot}$ Nabokja(乾栗 ${\cdot}$ 薏苡仁). And we analysis new prescription of the interior disease and get the basic prescription that is Jojung-tang(調中湯), Galgunhagi-tang(葛根解肌湯) and Isunggugo-hwan(二聖救苦丸) of old prescription. However, pharmacology of Eumhyulmogal is different from the other symptom and disease. That contain the pharmacology of Chungsimyunja-tang(淸心蓮子湯). We can't find Chungsimyunja-tang from the discussion of symptom and disease. So we can estimate that Chungsimyunja-tang belongs to the prescription of Eumhyulmogal.
