As major industries become information-centered, business transactions and information-sharing processes are being computerized and automated, which ultimately re-defines electronic commercial transactions in a broader context. Business documents are the basic tools for corporate transactions. The use of business documents in electronic commercial transactions has increased markedly and this sphere is rapidly being extended to include information sharing between companies. XML(extensible Markup Language) was selected as the focus for this thesis. XML ran help to make a complicated and data-rich document easy to share. The thesis proposes a business XML document editing system, comprised of a style document editor for business XML document structure, business documentation, and business document presentation, along with a business document transformation system which makes a transformation possible regardless of platform or using various corporate document standards.

At present, the electronic document is being processed in WYSWYG mode. For this, a document is structured by the logical structure and the physical structure, and is presented by the markup language. After XML is announced, an application scope of the electronic document is extended from interchanging to searching. However, in point of output quality, a XML document image on a browser has lower quality than a general document image on desktop publishing. The reason is which output function of a browser has not capability for high quality printing. The W3C developed XSL-FO(XSL-formatting Object) for style sheet formatting and PDL(Page Description Language) as like Postscript is already developed and used widely. In this paper, we designed the Postscript-Converter to get a high quality document image by converting XSL-FO into Postscript format.

This paper is for the design and implementation of SGML presentation system to format based on DSSSL (Document style semantics and specification Language). ISO proposed DSSSL as the technological standard for formatting and transforming SGML document. So, the body of this paper shows the design of this system in accordance with the model defined in DSSSL. This system, which is able to provide Korean, has Parsing function of arbitrary DTD, SGML document and DSSSL styles sheet, and contains a formatter that can manage various details, such as table, list, picture and others, as well as text.

In this paper, we propose a system to convert a video motion into cartoon-style animation automatically. Our system is a new video cartoon stylization method that can apply natural transformation with satisfying physical constraints. It applies physically reasonable transformation to a selected video object with considering physical information such as momentum, movement direction and force. We construct several deformation scenarios which correspond with traditional animation techniques, then a scenario can be easily selected to apply the effects. Finally, this system gene-rates a dynamic cartoon-style video by timing control and a cartoon rendering technique.

This paper is addressed to a design and implementation of Korean voice web browser using voice technologies for controling web browser and selecting contents in the web document, and converting them to voice after HTML analysis. Main feature of this web browser is universal design which considers both of normal person and visual disabled, allows multi-modal interface. As voice interface for visual disabled, it supports tree structure which allows to recognize web document structure easily by only voice guidance regardless of frame usage, can handle all elements described as tag in the web document, identify them as predefined different voice property according to element property. This method gets rid of additional guidance voice for element property without audio style sheet or additional programming effort.

In this paper, an accurate remote gaze tracking method with two cameras is presented using a modified Starburst algorithm and honography normalization. Starburst algorithm, which was originally developed for head-mounted systems, often fails in detecting accurate pupil centers in remote tracking systems with a larger field of view due to lots of noises. A region of interest area for pupil is found using template matching, and then only within this area Starburst algorithm is applied to yield pupil boundary candidate points. These are used in improved RANSAC ellipse fitting to produce the pupil center. For gaze estimation robust to head movement, an improved homography normalization using four LEDs and calibration based on high order polynomials is proposed. Finally, it is shown that accuracy and robustness of the system is improved using two cameras rather than one camera.

Recycling of aluminum dross is an important issue in the secondary aluminum industries. In this study, aluminum dross generated in the domestic secondary aluminum industry was processed to use it as raw material for producing alumina refractories. Sample dross was classified according to its size. The dross smaller than 1 mm was leached with sodium hydroxide solution to extract the remained aluminum from the dross into the solution. and then aluminum hydroxide precipitate was recovered from the leach liquor. The waste residue in the leaching was washed, dried and roasted. Most remained metallic components in the residue was changed into oxide through the processes. The roasted dross was made into alumina castable refractories by mixing with aggregates and a binder. Bending strength of the tested castable specimen was over $25\;kg/\textrm{m}^2$ and compressive strength over $80\;kg/\textrm{cm}^2$, which satisfied the Korean Standard value respectively. From the results, it was suggested that this process could be applicable to recycling of aluminum dross.

A generative adversarial network (GAN) is a network in which two internal neural networks (generative network and discriminant network) learn while competing with each other. The generator creates an image close to reality, and the delimiter is programmed to better discriminate the image of the constructor. This technology is being used in various ways to create, transform, and restore the entire image X into another image Y. This paper describes a method that can be forged into another object naturally, after extracting only a partial image from the original image. First, a new image is created through the previously trained DCGAN model, after extracting only a partial image from the original image. The original image goes through a process of naturally combining with, after re-styling it to match the texture and size of the original image using the overall style transfer technique. Through this study, the user can naturally add/transform the desired object image to a specific part of the original image, so it can be used as another field of application for creating fake images.

'UFO2MF' and 'Korean MetaFont Generator' have been developed to convert UFO codes to the corresponding Metafont codes by using outline editing methods. However, 'UFO2MF' cannot express smooth curves because it use only reference points without using control points. And 'Korean MetaFont Generator' can easily design the curve of characters, and supports Hangul characters, but this system does not support Roman characters. In this paper, we propose a UFO2xMF system, which can convert both Korean and Roman characters from outline text information into Metafont codes. UFO2xMF can apply attribute values which can change the shape of letters during the conversion of Metafont code. It is also a highly compatible system that can convert the characters of various languages not only Korean characters but also Roman and other characters into Metafont codes by applying letters with baseline and centerline of gravity.

Because of various style-sheet and Korean-Fonts, converting from WYSIWYG types of HTML data to forms of PDF has many limitations. In print-work areas, for printing specific fonts, it has to use CMYK colors instead of RGB colors. This paper describes about the process to make web font to printing PDF files, which is high resolution image captured document based on HTML, by using COM component feature of hardware.
