A systemic approach to behavior on the basis of human psychology is needed for behavior-centered space design. Also, the recognition that human and environment, in all, have complementarity is needed- human and space shall be understood as a general phenomenon, supposing interaction. Design of behavior-oriented space means configuration and coordination of physical subjects as well as understanding, analysis and reflection of psychological and behavioral phenomena. It is analysis of a private individual as well as understanding of interaction between human groups, as well. In respect of space recognition, analysis not on material movement but on energy circulation and variable is important. It means that the understanding of user's behavior and psychology does not orient reasonable purpose just for convenience. That is, such understanding intends to understand behavioral patterns and psychological phenomena between space and human beyond the decomposition of structure of human and space into physical elements and the design based on standardized data. Thereby, more human-oriented space design might be implemented by the understanding of behavioral essence. Also, a user-centered design process from another viewpoint might be created, and the general amenity among man, space and environment - better environmental quality - might be produced. For this, the consciousness of human activity that is, activity system shall be ahead of it, and the approaches for design shall be implemented into a process not in predictive ideas but in semi-scientific system. On the basis of the above view, this study was attempted to investigate the orientation of design to recognize space as another life, and explore a process where it is drawn into a design language on the basis of human behavior. If the essence of space behavior and the activity system are analyzed through user observation and it is reflected upon a space design program and then developed into a formative language, a new design process on human and environment might be produced. In conclusion, the reflection of user's behavior and psychology into design, contrary to existing public space design based on physical data, can orient quality improvement of human life and ultimately be helpful to the proposition, 'humanization of space'.

This study investigates the characteristics of Mario Botta's single-family houses. Eight of his housing project which are deemed important in the historical development of housing he been selected for the purpose their elevations plans loggie and interiors are analyzed and evaluated. Through this study the followings are realized ; $\circled1$ The rationality of his interior space comes from Le Corbusier's housing projects. $\circled2 His expression of elevations has developed from Louis. I. Kahn's language and Carlo Scarpa's technique. $\circled3$ The rationality of Corbusier's houses and expressiveness of Kahn's and scarpa's projects together led to his functional solution of internal program an and the creative external images of his own. $\circled4$ The originality of this house results from his creative vision and ability to reinterpret the existing expression and principles in the light of time and space.

Typical helicopter simulation programs rely on differential equations of a closed form. However, since these equations are derived using various assumptions, their usefulness is limited to small flight regions and specific model types. This paper presents a component based rotorcraft simulation program. The program adopts methods of multi-body dynamics and is written in an object-oriented programming language. The program was validated using an AH-1G helicopter simulation. The trim results are well matched with flight test data. It is also shown that program is capable of running in real-time on a desktop computer.

One of the big difference between Aalto and other modem architects lies in an attitude that Aalto went beyond the principle of dogmatic functionalism. As an architect of Northern Europe, Aalto made unique architecture that showed both the language of modem architecture and vernacular architecture. He presented the best example which showed modernity in architecture without losing the meaning of the context including site, region and cultural tradition. With this background, Aalto developed his own typological design approach. As Wolfsburg church was designed in his prime of time, it showed the origin and evolutionary process of religious architecture as well as general features of Aalto's design. Clustered site plan, dynamic space of interior, the adequate control of natural light are representative characteristics found in Aalto's religious architecture. Wolfsburg church also demonstrate these features in more specific way including the continuity of wall and ceiling that showed spatial dynamics, free opening of wall which reflects on functions, and careful adjust of natural light. As a result, Aalto showed his typological design strategy that added new design ideas to the accumulated design vocabularies in the design of Wolfsburg church.

Spacecraft mission planning functions including event prediction, mission scheduling, command planning, and ground track display have been developed for the KOMPSAT-2 mission operations. Integrated event prediction functions including satellite orbital events, user requested imaging events, and satellite operational events have been implemented. Mission scheduling functions have been realized to detect the mission conflicts considering the user specified constraints and resources, A conflict free mission scheduling result is mapped into the spacecraft command sequences in the command planning functions. The command sequences are directly linked to the spacecraft operations using eXtensible Markup Language(XML) for command transmission. Ground track display shows the satellite ground trace and mission activities on a digitized world map with zoom capability.

This paper proposes a new color segmentation method of vehicle license plates in the RGB color space. Firstly, the proposed method shifts the histogram of an input image rightwards and then stretches the image of the histogram slide. Secondly, the method separates each of the three RGB color components and performs the adaptive threshold processing with the three components, respectively. Finally, it combines the three components under the condition of making up a segment color and removes noises with the morphological processing. The proposed method is implemented using C language in an embedded Linux system for a high-speed real-time image processing. Experiments were conducted by using real vehicle images. The results show that the proposed algorithm is successful for most vehicle images. However, the method fails in some vehicles when the body and the license plate have the same color.

A variety of design processes from 2D graphic to 3D models are meeting improved consumers' confidence of modern clients. However, the current design methods are limited to meet consumers' needs and express a design concept what a designer wants to show. Therefore the study here tries a test of hybrid space simulation combined with previous models and digital media technology, which can be used for multiple contents. The study can contribute to suggesting virtual space simulation that can help clients' spatial understanding in this media era and deliver emotional language of designers as well by utilizing the strong point of multi-sensible media.

In ubiquitous environments, many applications need to process data with time and space dimensions. Because of this, there is growing attention not only on gathering spatiotemporal data in ubiquitous environments, but also on processing such data in databases. In order to obtain the full benefits from spatiotemporal data, we need a data model that naturally expresses the properties of spatiotemporal data. In this paper, we introduce three spatiotemporal data models extended from temporal data models. The main goal of this paper is to determine which data model is less complex in the spatiotemporal context. To this end, we compare their query languages in the complexity aspect because the complexity of a query language is tightly coupled with its underlying data model. Throughout our investigations, we show that it is important to intertwine space and time dimensions and keep one-to-one correspondence between an object in the real world and a tuple in a database in order to naturally express queries in ubiquitous applications.
