Since the early stages of philosophy in ancient Greece, reason has prevailed over sensation, based on the idea that it was the recognition of the ideal world existing as the archetype of objects. Abstract concepts followed geometric models, though they be invisible. However, from the beginning of 20th century, people began to be interested in the idea in metaphysical philosophy, that reason might not be a characteristic best representing the human spirit, and that a human being is composed of emotion, desire and the physical body, in addition to reason. The study shows that paintings and constructional space have shown similar changes through the stream of time, and have a synchronistic relationship within the range of the formative arts, based on the contemporary philosophy. First of all, it defines the change of contemporary thought and its analysis words. And consider the Corporality which is one characteristic of contemporary thought. This study shows the characteristic of the Corporality in the architectural space of Rem Koolhaas whom it selected the architecture who is influenced by Post-structuralism. In conclusion, It compares paintings and architectural space and looks into the correlations among them in the category of the Corporality which is a pont of view from contemporary thought. As a result of the comparison, the Corporality in paintings is defined as (1) An escape form Reason, (2) An emphasis of experienced events and (3) A destruction of forms. It defines the architectural space of Rem Koolhaas corresponding with the Corporality in paintings has a characteristic of (1) The space of Body without Organs, (2) Becoming spatial concept of events and (3) An Unrestrained Form.

In this paper, a longitudinal die insert fracture which occurred during cold forging of a high strength ball-stud with a sound die design nearly optimized empirically for relatively low strength material of SCM435 is introduced and the reason is revealed. A comparative study between SCM435 and ESW105 is quantitatively made using a thermoelastic finite element method for die structural analysis coupled with a forging simulator theoretically based on a rigid-plastic finite element method. It has been shown that the longitudinal die insert fracture caused from non-optimized value of shrink fit, emphasizing that the die optimal design is inevitable for cold forging of high strength materials.

Risk is the probability of an adverse event given exposure to hazard. There are many reason for unsafety situation without safety operation. The reason is no safety evaluation system in small enterprise. And then this study purposes safety management activities that is evaluation system for total safety efficiency's maximization. Therefore, in this study, this model that can evaluate quantitative activities in small enterprise that maximize safety efficiency wishes to do design using balanced scorecard. In other words, this study aims to suggest a performance measurement model reflecting the characteristics of safety evaluation system, especially the model for return manufacturing related to safety, and to develop the S-BSC(Safety-Balanced ScoreCard) measurement model using a weight lifetime value to which a relative weight is applied by using AHP based on the BSC.

Korea has a dark age in terms of culture in the last 20th century. Korea had been struggling between the Great Powers of the world in the imperialism and had sacrifice to keep our own culture itself. Japanese imperialist's a invasion, culture liquidation by Japan, Independence from Japan, Korean war and Influence by US are major bitter historical affair after close of Chosun Dynasty in the process of modernization. Therefore Korea couldn't stay in the center of world cultural core parts and was degraded as cultural consumption country which was provided oversea culture by other countries. Then Korea couldn't develop our unique traditional idea and culture. In the meantime there are both extreme phenomena; one is expulsion of other cultures absolutely and the other is only following western culture unconditionally like trimming policy in the end of colony age. These discreet and unfiltered western culture had been influenced Korea culture over the wide range strongly and resulted in cultural colony situation to produce western imitation culture without philosophy and traditional spirit. Even though Korea has met opportunity in the culture, we called "Han Trend", no formation of own culture is main reason for psychological panic. Korea furniture design is one of parts of lost of tradition culture and typical parts in reproducing western imitation culture. As a result furniture industry's major reason for loss value as exporting industry compared to other industries result in most of the furniture products without our unique identity. This situation become more deepen unfortunately. This report would like to suggest the direction of design with global competition capability and cultural identity to boost Korean furniture design industry by comparing, analyzing and speculating between design of Chosun dynasty and philosophy of modernism in western.

A German philosopher, Herbert Bolz predicted that the human way of thinking would be fundamentally and completely changed because of digital media and the 'Gutenberg-Galaxis', named by M.McLuhan which was symbolized of modern reason was doomed to be over. He thought that the limit of reason-centered European culture would be overcome by the up-to-date multimedia to revive the communication life. On this theory, he emphasized the emotional perception, 'aisthesis' which is original meaning of aesthetics. That is to say, he insisted on the restoration of communication media to enable the five senses' amusement condition mentioned by Kant. This thesis asserts that the representative hypermedia digital animation may play a key role to rehabilitate human sensibility pressed by reason centered modernism. Digital animation has the unique worth of Art that is firstly to deal with time and space and enable unlimited expressions and can communicate effectively as a characteristic synthetic medium which consists of intensive computer techniques. Based on the background, this thesis analyzes the possibility of the digital animation as a new medium. Especially, it is focused on the relations to the hypermedia theory of Norbert Bolz who is a media analyst and professor of a design college.

Preservation space is a functionally$\ulcorner$core$\lrcorner$in a museum. Gernerally, it is a common view that collections are exhibited within 5% of total stored collections. So that, part of collections are cycled exhibition space centering around preservation space, and that is a important mechanism of collections circulation in a museum. It is the best way that collections should be $\ulcorner$conserve$\lrcorner$ in a stable condition, but inevitably collections are exposed as stable condition, but inevitably collections are exposed as called $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$for 'showing' and the function of $\ulcorner$preservation$\lrcorner$for 'conserve'are contrary to each other's concept, so it is principle of scheme that these concepts should be functionally connected with and planned$\ulcorner$match$\lrcorner$. In addition, various studies (for example, comparative analysis of collections, examination of collections for conserved condition or special exhibition, and classification of new item, etc.) are worked in preservation space. Therefore, preservation space should not be considered as a warehouse, should be composed not only$\ulcorner$comfortable place to rest of collections$\lrcorner$but also $\ulcorner$part of study room$\lrcorner$in a museum. So that, environment of museum should be established by plan to preservation and management. The point of plan to museum is that minimize dangerous element for collections, and then develop an essencial element of space for$\ulcorner$conservation$\lrcorner$and$\ulcorner$exhibition$\lrcorner$. The reason why with a few exceptions (buildings which have being exposed or extremely minor part of collections) most of collections have been lasting its life during over hundreds of years with adapting itself to natural features, so scheme of preservation facilities should be made up with understanding and analysis generic character of collections, and then establish proper temperature and humidity environment.

In MIMO design, input and output units are different from each other. By this reason, the effect of larger units to smaller one is not trivial and there is no method of proper scaling, optimal scaling. In this paper, robust stability of MIMO LQG/LTR design are analised when the plnat inputs and outputs are scalled. The upper bound of model error to guarantee the robust stability is obtained, and gain margin and phase margins are computed with respect to scalling matrices.

This paper proposes a shaker system design for acceleration test of gimbal. Main reason of shaker system design is to give acceleration to the gimbal, which is moving and tracking the target on the tracking test equipment. The shaker system is mounted on the tracking test equipment. It uses the scotch yoke mechanism to have the constant movement in return. The Scotch yoke mechanism changes the rotational movement of constant velocity to simple harmonic motion.
