'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.

Attempt to use as a marker of natural objects directly in the real world, but there is a way to use the accelerometer of the smartphone, to convert the Frontal-View virtual, because it asks only the pitch of the camera, from the side there is a drawback that can not be converted to images. The proposed algorithm, to obtain the rotation matrix of axis 3 pitch, roll, yaw, we set the reference point of the yaw of the target image. Then, to compensate for the rotation matrix to determine Myon'inji any floor, wall, the ceiling of the target image. Finally, to obtain the homography matrix for obtaining the Frontal-View to account for the difference between the gyro sensor coordinate system and image coordinate system, so we can get the Frontal-View from the captured images through the projection transformation was designed. Was tested to convert Frontal-View the picture was taken in an environment smartphone environment surrounding floor, walls and ceiling in order to evaluate the conversion program Frontal-View has been implemented, in this paper, design and The conversion algorithm implementation, it was confirmed that to convert a regular basis Frontal-View footage taken from multiple angles.

This paper proposes an algorithm for automatically converting and displaying rainfall radar data on a 3D GIS platform. The weather information displayed like rainfall radar data is updated frequently and large-scale. Thus, in order to efficiently display the data, an algorithm to convert and output the data automatically, rather than manually, is required. In addition, since rainfall data is extracted from the space, the use of the display image fused with the 3D GIS data representing the space enhances the visibility of the user. To meet these requirements, this study developed the Auto Data Converter application that analyzes the raw data of the rainfall radar and convert them into a universal format. In addition, Unity 3D, which has good development accessibility, was used for dynamic 3D implementation of the converted rainfall radar data. The software applications developed in this study could automatically convert a large volume of rainfall data into a universal format in a short time and perform 3D modeling effectively according to the data conversion on the 3D platform. Furthermore, the rainfall radar data could be merged with other GIS data for effective visualization.

When you convert word processor files with large amounts of input data to PDF files in on/off line, current PDF conversion solutions do one of the source files to perform the conversion task in the Windows PDF virtual printer environment. Depending on the size of the original PDF file conversion speed to convert PDF to do a large amount of different and if you are performing a very slow speed. When you convert files to PDF in this sequence, depending on the capacity of the original file, PDF conversion rate is different, if automating a mass conversion to the PDF, the speed is very slow. In this paper, the PDF conversion which can use the Windows Terminal Server from one Windows Server when performing a PDF conversion processing of the source file, to create a multi-session Terminal, to perform the PDF conversion process at the same time was studied.

This study would verify the validity of two transmission technology, 'Clear QAM' and '8VSB'. 'Clear QAM' and '8VSB', the transmisson technology, have been suggested as the concrete alternatives in the situation that half of subscriber of multi channel tv service have been still out of benefit from digital convert. In this study, we have shown that the introduction of 'Clear QAM' and '8VSB' should ease economical burdens and information minority group without extra set-top box. But there is another concern that it should negatively affect on the contents industry by a devaluation of the multi channel tv service or by an infringement of copyright. In these reasons, it is still difficult to solve the related concern, though the government have to set up the politic goal for the related industry as well digital convert. This study suggested that Korea Communication Commission consider above-mentioned technology temporarily, and reconsider 'Clear QAM' around the completion of the digital convert project.

Generally, if RGB image is sent to the printer when we print a digital photograph, the printer will convert RGB to CMYK by the inner built-in drive. Because the difference between color domain of RGB and CMYK will cause that change and difference. The most common way to solve the problem is to convert colors by using ICC profile at RIP software or to adapt automatic color converting from the software of the original printer. So we intended to study show which way is most efficient to the digital output and which color mode device is the best based on the printer's own drive in this paper. we tried to observe and check the extended range of color space such as AdobeRGB as well as CMYK and sRGB. Then we made sure which is the suitable color space. Besides, When we convert RGB mode into CMYK mode by utilizing RIP software and adapt the printer's ICC profile made by our selves, we evaluated the output we get and compared the result with extended RGB image. The results are as follows. In case of RGB mode, the printer requests RGB, and that makes the color space more efficient than CMYK's. Converted to CMYK by utilizing RIP software, the chroma is more linearized than the one produced with its' own driver. Compared with sRGB mode's color gamut, AdobeRGB mode's color gamut and CMYK mode's color, CMYK mode's color gamut is the smallest among 3 of them. CMYK mode's color gamut by utilizing RIP software can be changeable. that can be small and narrow or wide and broad. In other words, the volume of color gamut depends on how CMYK is linearized. The color space of sRGB is more advantageous than the one of AdobeRGB in color-reproduction printed. But in the group $-b^*$, the chroma leaves behind in terms of reproduction, In the group of $-a^*$, the chroma is excellent relatively. Visual evaluation of the image, AdobeRGB image has not many reproduction colors. Specially, according to printers' characteristics, Group B of AdobeRGB and sRGB color space is a long way behind In terms of reproduction but Group Y is excellent relatively.

This review on biofiltration is intended to provide an engineering concept such as removal efficiency, maximum load, elimination capacity and so on. Besides, modeling concept of biofilter is also supplied for designing biofilter system. Quantitative data generated in our research group is shown to explain the engineering concept as well as the modeling idea.
