This study is focused on subjective images that are produced before visualization in the digital information environment and on characteristics of objective, dynamic image expression that specifies the subjective images. In this study, the visual world that works in the action of "see"is expanded into vision of eyes, vision of brain, and vision of camera. Also we have redefined the definitions of image and its materialized image, yeongsang. It is defined that image contains a strong meaning of consciousness and mind, and that yeongsang involves vision in which constantly changing information of light is created and reproduced by physical processes. We made it clear that image expression in the 21 st century is becoming more generalized, simplified, and concentrated, by the digital technology, from existing specific non-real images to "informationalized" non-real images. This means that there exists an intrinsic difference in the expressional form of the modern analog environment and that of the recent digital environment in the area of yeongsang communication. Along with development of technology, image information raises plastic reality through indirect experience in the virtual space by expanding the sensual faculty of human. However, there also is a tendency for humans to rely more on technology instead of utilizing their creative faculty. Image expression by“the digital information environment” in the 21st century will pursue two sides; one is to shift from external expression of the human body in the cyber space to internal expression, and the other is to internalize the image world and make it connected worldwide. Further research is necessary in these fields.ary in these fields.

In virtual reality, there are increasing qualitative development in service technologies for realtime interaction system development, 3- dimensional contents, 3D TV and augment reality services. These services experience difficulties to generate depth value that is essential to recover 3D space to form solidity on existing contents. Hence, research for the generation of effective depth-map using 2D is necessary. This thesis will describe a shortcoming of an existing depth-map generation for the recovery of 3D space using 2D image and will propose an enhanced depth-map generation algorithm that complements a shortcoming of existing algorithms and utilizes the definition of depth direction based on the vanishing point within image.

We live seeing, touching, or throwing on considerable textile in our life consciously and unconsciously. Since a Korean-style house is a dwelling space in life style of sitting on the floor with ondol(Korean floor heater), use of textile is limited to bedding goods. However, as western life style takes firm root, use of textile for interior design is increasing. As well, as apartments and foreign style houses have gotten lodgment since 1980, life style is being changed rapidly. So, textile became required factors in dining space where little textile existed. Through literature, history of textile is considered and design image concept is created based on the consideration. In addition, the created concept can be applied to various textile design, which can be a good tool to express eating culture of the country as well as the country's image.

The purpose of this project is to greatly elevate the image of a high-technology wireless communication company by improving its office space environment through remodeling techniques. In order to accomplish this goal, the design concept was established in the direction of harmonious beauty with maximized functionality and aesthetics. Specifically, an efficient traffic line was planned in consideration of the connectivity between mutual spaces, and smooth yet strong formal aesthetics was given to such things as planes, frontal surfaces, and ceiling design, so as to do away with the existing authoritarian atmosphere and create an image of a futuristic company.

The aim of this study is to propose the predictive index and analyze the effect of lightsources and colour image types in the residence and office interior.This study was consisted of four steps, and was carried out as follows. 1) The condition of experiment was set up by optical characteristic of lightsources and colours. 2) The scaled model space was manufactured for the evaluation of the same condition by each space. And, some piece of furniture was manufactured for the representation of each space. 3) The emotivity response of lightsources and colours was measured. 4) Results of the evaluation of lightsources and colours were compared and analyzed by conditions, and the predictive index was proposed by image types.

The cylindrical environment maps of image-based representation methods make high-quality, simple and low-price real-time navigation possible. In this paper, we propose a method to navigate from one viewpoint to the next in the virtual inside space, composed of several cylindrical environment maps. Our system is classified into the two modules. first of all, the panoramic image viewer that employs the rotation and zoom-in/out methods to navigate the virtual inside space, such as the Quicklime VR. The other is smooth real-time navigation using cubic mesh interpolation when the viewpoint moves from one environment map to another in the virtual space.

In the integration of Sommerfeld type for space domain Green's function, a accurate closed-from Green's function method provides more exact solution than the typical complex image method and two-level method. The accurate closed-form Green's function method is applied to obtain the space domain Green's functions of planar structures with general sources. Please put the abstract of paper here.

Band-limited filtering will be applied to remove interference resulted from two neighbored channels in the transmission of KOMPSAT-5 X-Band image data. In that case, receiver in ground station should prepare righteous matched filter to avoid huge BER degradation depending on the matched filter of COTS receiver. As an effort to simulate the bandlimited filtering, test filter was designed and manufactured on the basis of main specification for output filter of KOMPSAT-5 satellite. Consequently, 1.8dB of BER degradation was measured at the output of test band-pass filter, but the degradation was downsized up to 0.4dB thanks to the adaptive matched filter of COTS receiver.

Lunar sodium observations are being prepared by a group of WCU scientists at the Kyung-Hee Observatory. We have been working on 3-D Monte Carlo simulations of the lunar sodium exosphere since 2009, and we need to obtain additional sodium images in order to constrain our models. Using a newly-designed simple coronagraph which is optimized for lunar observations, we plan to make direct sodium image observations. We present the structure of the planned coronagraph, optical-image observation plans, and spectroscopic observation plans of the lunar tail. We will also present updated results from the 3-D Monte Carlo simulations.
