This study is about Christian Dior's and Martin Margiela's fashion works that create 'New look' which leads the periodic ideology, philosophies, circumstances and the trend at that time. For the systematized interpretation, this study investigates the iconology of E. Panofsky, E. H. Gombrich and N. Goodman. Based on their theories, iconological analysis paradigm is made into four phases: I. Recognition of iconological form, II. Analysis of External Elements, III. Analysis of symbolic meanings and artistic will and IV. Aesthetic enjoyment and communication with a viewer. Christian Dior treats woman as a organic and architectural structure. He falls in love with himself such as narcissus and woman who wears his works. Dior's ego is visualized by woman and his works which are the symbol of narcissism and beauty. Martin Margiela makes form of clothes and at the same time destroys. Margiela deconstructs aura of clothes and tries to make it unfamiliar. Also he changes traditional idea of beauty and creates 'ugliness' which is a notion of dialectic. Margiela transforms elements of clothes which brings variation of thinking and makes it possible to create new look. Christian Dior and Martin Margiela are the creators of new look which visualizes the notion of habitus that is the space of self-exists. Fashion dose not have to be what people wears but it could be an image itself. It means that fashion is a part of ontology and it is a 'New look' which is based on economy, the standard of periodical beauty and ideal aspects. The creation of clothes is a work of embodiment of human being where it constructed or deconstructed.

The objective of this study is to develop and validate a numerical method which can handle the multi-rotor aerodynamic characteristics. For the purpose of power estimation, table look-up method is implemented to the existing unsteady panel code that is coupled with a time-marching free wake model. Also, the Reynolds number scaling is implemented for the application to various regions of Reynolds number. The computed results are validated against the available experimental data for coaxial and tandem rotors. In the validation case for the coaxial rotor, more accurate result is acquired when the thickness effect is considered. The wake instability problem occurs at a particular separation distance between the rotors for tandem rotors. The wake instability is avoided by setting the single-rotor wake geometry as the initial wake geometry for the multi-rotor analysis. The estimated result for rotor separation effect is compared with the result of the momentum theory.

In this paper, based on the characteristics of proportional navigation, a composite guidance law is proposed for impact angle control of passive homing missiles maintaining the lock-on condition of the seeker. The proposed law is composed of two guidance commands: the first command is to keep the look angle constant after converging to the specific look angle of the seeker, and the second is to impact the target with terminal angle constraint and is implemented after satisfying the specific line of sight(LOS) angle. Because the proposed law considers the seeker's filed-of-view(FOV) and acceleration limits simultaneously and requires neither time-to-go estimation nor relative range information, it can be easily applied to passive homing missiles. The performance and characteristics of the proposed law are investigated through nonlinear simulations with various engagement conditions.

In this paper, the terminal homing loop with a IIR-type strapdown seeker and a roll rate gyroscope is proposed. Basically, the proposed homing loop is based on the look-angle-control guidance. Since the range of the seeker is strictly limited, the missile is delivered to a point to lock the target on the seeker via non-guided flight during the midcourse guidance. The non-standard firing table is developed to compensate the wind and the target movement. To secure the delay margin is very important to prevent the instability of the homing loop when the time delay of the seeker is included. To validate the proposed homing loop, the 6-DOF nonlinear simulation is performed, and the Monte-Carlo simulation is also done for checking the robustness for the various kinds of uncertainty.

We can use panorama systems or image based modeling systems when we want to make 3D space model and look around result. Panorama systems make 3D model to stitch images and map cylinder or cube. The structure of 3D model, made by panorama system, is not same as structure of a real room, so user can't infer a real structure. Typically, Image based modeling systems work on a desktop computer. That makes it difficult to reconstruct 3D model in real time and take long time for processing. In this paper, we propose a 3D panorama modeling system that uses images on a mobile device. This system reconstructs a 3D space model, similar with a real room in real time, from multiple images captured part of rooms. Using this system, user can reconstruct various shape of space and look around a 3D space model.

We have developed an attitude sensing S/W system, one of modules of Mission Analysis System(MAS), which simulates attitude sensing data as almost the same as the real sensor of a satellite in orbit. When attitude elements($alpha,delta$) of a satellite and positions of Earth, Moon, and Sun are given, the S/W system calculates look angles and dihedral angles of each celestial bodies relative to the rotations axis of the satellite. It consists of two sub-modules : One is ephemeris service module which consider the perturbations of four planets(Venus, Mars, Jupiter, Saturn) for positions of Sun and Moon and 4 $\times$4 earth gravitational potential terms for a satellite's position. The other is attitude simulation module which generates attitude sensing data. Varying the rotational axis of a satellite and it's orbital elements, we simulated the generating attitude sensing data with this S/W system and discussed their results.

This study is aimed to look into the craftsmanship non-educated constructors in Korean-style secondary stations(Gong-So) of Naepo region which is located in the northwestern Chungcheongnam-do. Although the area was persecuted as one of three cradles of Korean Catholicism, Catholic activities flourished there. The 13 cases of Korean-style secondary stations were selected through a survey report list about modern cultural assets of Chungcheongnam-do published in december 2004. This study examined the methods of plan layout and framework of Gong-So to look into craftsmanship of non-educated constructors, the results are as follows; The methods of plan layout are divided into three types according to existence and arrangement of inner column(Nae-Ju); 'Layout with Nae-Ju' is considered as the primary form of Korean-style Gong-So with using regular Nae-Ju. 'Layout with the different position of the center between Nae-Ju and exterior column(Oe-Ju)' and 'layout without Nae-Ju' is appeared in Korean-style Gong-So which is important to assembly and alter function. The methods of framework are appeared variously according to different plan layout for securing worship space. The unusal beam(Chung-Ryang) is used to solve different spans of altar and narthex. When space was formed widely without Nae-Ju, diagonal members and M letter type rafters are used, they are influenced by the technique of western wooden roof truss.

Some problems facing the cities in modern times begin to be highlighted due to the development into the information-oriented society via the stage of industralization. The structures built centering on the second industries have become superannuated to degenerate as horrid objects while losing their purposefulness with the emergence of the information age. In designing a hotel space where people stay temporarily unlike the housing space for a permanent stay, housing designers are making efforts to work on space design that could be more imprinted in the mind of the users. As the fruit of their sheer labor, the space design in modern hotel design comes to direct a diversity of atmospheres by virtue of various art genres which try to apply it to a space by borrowing it and changing its appearance. Thus, this study aims to look into how the gradually evolving conversion design hotel come to be recreated as an urban regeneration space while retaining the value of the space used in the past, and to analyze & systematize its subsequent design patterns applied to conversion design hotel space with focus on the recent cases.
