Today many countries consider the culture and technology industry as a high value-added industry, and make intensive investments into cultural content for its growth. In the culture and technology industry, the OSMU (One Source Multi Use) business structure, which creates content using diverse media based on one original work and thus generates a high added value, has received much attention. Recently Korea has also witnessed an increase in the cases in which the cartoon medium is converted into movies or drama. Cartoons are now put to the most use as an original source, in which the process of active secondary reproduction and recreation are taking place. In the process of recreating original works, media characteristics function as an important variable. Stories are newly reproduced by the detailed information (form) characteristics of each medium. Despite those developments, however, there are not as many active comparative studies on media-converted works as there are actual productions of them, which calls for a need to more fully activate specific comparisons of cases. By comparing and investigating original works and secondarily recreated ones through media conversion, the study made comparisons between the cartoon and movie medium and described the common and different features of the two media in terms of detailed information characteristics. In order to provide a specific case, it also analyzed the cartoon Tajja and movie Tajja through media conversion, focusing on 'conversion of narrative structure.'

This paper proposes the system and method for converting the contents based on DLNA. Digital Media Controller (DMC) compares the media format of content which Digital Media Server (DMS) provides with the media format which Digital Media Renderer (DMR) supports and then, the content is converted dynamically. The interaction between home devices can make a conversion of contents dynamically and it enables people to enjoy the multimedia contents they like to watch whenever/wherever they want.

In this study, we modified CT images of femoral head in consideration of anatomically meaningful structure, proposing the method to augment the training data of convolution Neural network for segmentation of femur mesh model. First, the femur mesh model is obtained from the CT image. Then divide the mesh model into meaningful parts by using cluster analysis on geometric characteristic of mesh surface. Finally, transform the segments by using an appropriate mesh deformation algorithm, then create new CT images by warping CT images accordingly. Deep learning models using the data enhancement methods of this study show better image division performance compared to data augmentation methods which have been commonly used, such as geometric conversion or color conversion.

Most carbohydrates exist in nature in an insoluble state, which reduces their susceptibility towards various carbohydrases. Accordingly, they require intensive pretreatment for structural modification to enhance an enzyme reaction. The direct conversion of insoluble carbohydrates has distinct advantages for special types of reaction, especially exo-type carbohydrase; however, its application is limited due to structural constraints. This paper introduces two novel heterogeneous enzyme reaction systems for direct conversion of insoluble carbohydrates; one is an attrition coupled enzyme reaction system containing attrition-milling media for enhancing the enzyme reaction, and the other is a heterogeneous enzyme reaction system using extruded starch as an insoluble substrate. The direct conversion of typically insoluble carbohydrates, including cellulose, starch, and chitin with their corresponding carbohydrases, including cellulase, amylase, chitinase, and cyclodextrin glucanotransferase, was carried out using two proposed enzyme reaction systems. The conceptual features of the systems, their reaction characteristics and mechanism, and the industrial applications of the various carbohydrates are analyzed in this review.

SDR 영상과 함께 HDR 버전 제작을 함께 요청하는 프로젝트가 점점 늘어나는 추세다. 어느 정도 규모의 업체에서는 고가의 HDR 레퍼런스 모니터와 라이선스 비용을 지불하고 비교적 편리하게 작업할 수 있다. 상황이 그렇지 못할 경우 최소의 비용으로 장비를 구매하고, 기존 장비와 호환성을 점검하고, 컬러링 어플리케이션에서 지원하는 기능을 활용하여 최선의 워크플로를 구성해야 한다. 또한 SDR 버전을 HDR 버전으로 제작하거나 HDR 영상을 SDR 버전으로 변환할 때 장면마다 다시 보정하는 일을 최소화하기 위한 세심한 보정이 필요하다. 본 원고에서는 동시에 촬영된 BT.709 기반의 HD 프록시 영상과 RAW로 촬영된 UHD 원본 영상을 활용하여 변환 작업에서 주의 깊게 살펴보아야 할 사항들을 알아보도록 하겠다.

ATSC (Advanced Television System Committee) has specified 18 video formats for DTV (Digital Television), e.g., scan format, size format, and frame rate format conversion. Effective MPEG-2 video transcoders should support any conversion between the above-mentioned formats. Scan format conversion Is hard to Implement because it may often induce frame rate and size format conversion together. Especially. because of picture type conversion caused by scan format conversion, the computational burden of motion estimation (ME) in transcoding becomes serious. This paper proposes a fast ME algorithm for MPEG-2 video transcoding supporting scan format conversion. Firstly, we extract and compose a set of candidate motion vectors (MVs) from the input bit-stream to comply with the re-encoding format. Secondly, the best MV is chosen among several candidate MVs by using a weighted median selector. Simulation results show that the proposed ME algorithm provides outstanding PSNR performance close to full search ME, while reducing the transcoding complexity significantly.

In this paper, the algorithm which can convert a 2D image into a 3D Model will be discussed. The 2D picture drawn by a user is scanned for image processing. The Canny algorithm is employed to find the contour. The waterfront algorithm is proposed to find foreground image area. The foreground area is segmented to decompose the complex shapes into simple shapes. Then, simple segmented foreground image is converted into 3D model to become a complex 3D model. The 3D conversion formular used in this paper is also discussed. The generated 3D model data will be useful for 3D animation and other 3D contents creation.

Citron peel oil was extracted from citron (Citrus funas) fruit by steam distillation, and was used as starting material for microbial conversion to synthesize attractive flavor compounds by using Enterobacter agglomerans 6L. E. agglomerans was isolated from citron peel and was able to metabolize the citron peel oil and grew well ($A_{600}:\;3.0$) on the citron peel oil as the sole carbon source. Multiple terpene metabolites were produced by E. agglomerans 6L on M9 salt media with citron oil vapor. The identified bioconversion products from the citron peel oil included trans-2-decenal, octanol, $\delta$­valerolactone, $\gamma$-valerolactone, cryptone, hydroxycitronellol, cuminol, and $\gamma$-dodecalactone.

In this paper, we describe a couple of methods for Frame Rate Up Conversion (FRUC) in Multi-View system. First, we introduce View Synthesis scheme that generates virtual views and FRUC that interpolates new frames between consecutive frames. Then, we introduce two applications of FRUC. One is a traditional application. The other is an application that uses feature of Multi-View system. Then we compare each result of two applications.

Complex permittivities of material in a wide bandwidth are measured by using an open-ended coaxial probe. To obtain a confident complex permittivity profile, the accuracy of measured reflection coefficients and the stability of the conversion model should be guaranteed in advance. In this paper, the sensitivity of our conversion model is analyzed by employing two instruments with different uncertainties. And various factors effected on the accuracy of measured reflection coefficients are investigated in experiment.
