ITK-SNAP (http://www.itksnap.org) and 3D Slicer (CMFreg extension module; www.slicer.org) are open-source softwares which can be used for superimposition of cone-beam CT images. For superimposition, segmentation of bone is done with ITK-SNAP, and then voxel based superimposition of CBCT images can be performed using 3D Slicer. 3D Slicer has various visualization modules which are not provided in common commercial programs. 'Models' module is used to visualize two overlapping three-dimensional images, and this allows various visualizations by changing view mode and color of the model. In addition, differences between two CBCT images can be represented in a color map using 'ShapePopulationViewer' module. This report introduces how to superimpose and visualize CBCT images using ITK-SNAP and 3D Slicer, and the usefulness and limitations of both softwares will be discussed in comparison with commercial softwares.

Scanners play an important role in digitally reproducing the color and imaging of original documents used in public offices; however, the current system lacks a standard for digitized documents created by scanners, complicating efforts to create a digitized system. In particular, macrography cannot guarantee the accuracy and reliability of digitalized color documents, pictures, and photographs created by scanners. To this end, we develop a standardized evaluation tool and test target to certify digitalized documents created by a scanner in the domestic environment. In this study, we enhance the accuracy and reliability of scanned data to create an advanced standard evaluation tool for scanners. Moreover, to produce a scanner certification standard, we overcome existing problems related to the growing market. We anticipate that this new standard will see a high degree of application in the current environment.

For medical students and doctors, knowledge of the three-dimensional (3D) structure of brain is very important in diagnosis and treatment of brain diseases. Two-dimensional (2D) tools (ex: anatomy book) or traditional 3D tools (ex: plastic model) are not sufficient to understand the complex structures of the brain. However, it is not always guaranteed to dissect the brain of cadaver when it is necessary. To overcome this problem, the virtual dissection programs of the brain have been developed. However, most programs include only 2D images that do not permit free dissection and free rotation. Many programs are made of radiographs that are not as realistic as sectioned cadaver because radiographs do not reveal true color and have limited resolution. It is also necessary to make the virtual dissection programs of each race and ethnic group. We attempted to make a virtual dissection program using a 3D image of the brain from a Korean cadaver. The purpose of this study is to present an educational tool for those interested in the anatomy of the brain. The procedures to make this program were as follows. A brain extracted from a 58-years old male Korean cadaver was embedded with gelatin solution, and serially sectioned into 1.4 mm-thickness using a meat slicer. 130 sectioned specimens were inputted to the computer using a scanner ($420\times456$ resolution, true color), and the 2D images were aligned on the alignment program composed using IDL language. Outlines of the brain components (cerebrum, cerebellum, brain stem, lentiform nucleus, caudate nucleus, thalamus, optic nerve, fornix, cerebral artery, and ventricle) were manually drawn from the 2D images on the CorelDRAW program. Multimedia data, including text and voice comments, were inputted to help the user to learn about the brain components. 3D images of the brain were reconstructed through the volume-based rendering of the 2D images. Using the 3D image of the brain as the main feature, virtual dissection program was composed using IDL language. Various dissection functions, such as dissecting 3D image of the brain at free angle to show its plane, presenting multimedia data of brain components, and rotating 3D image of the whole brain or selected brain components at free angle were established. This virtual dissection program is expected to become more advanced, and to be used widely through Internet or CD-title as an educational tool for medical students and doctors.

미디어의 영상은 우리의 생활 속에 일부가 되어있으며, 사람들은 다양한 영상으로부터 정보를 얻기도 하고 판단이나 행동의 근거로 삼기도 한다. 특히 시사다큐멘터리는 사회적으로 중요한 이슈에 대해 정보를 제공할 뿐만 아니라, 찬성과 반대의 의견을 형성시키기도 한다. 영상을 통해서 전달되는 인터뷰는 얼굴 표정, 몸짓 등을 직접 보여줌으로써 신뢰감과 사실성이 뛰어나 강력한 전달 효과를 가지게 된다. 따라서 인터뷰의 영상 표현법의 차이에 따라 수용자에게 전달되는 메시지의 영향력이 다르게 나타날 수 있으므로, 인터뷰 영상의 표현법에 대한 연구는 중요하다. 본 연구는 인터뷰의 영상표현에 대한 실증적 연구를 위하여 국내 3개 방송사의 대표적인 시사다큐멘터리 프로그램에서 각각 5편씩 총 15편을 선택하여, 다큐멘터리에 나오는 인터뷰 샷 전체에 대한 정량적 분석을 시도하였다. 영상표현의 분석틀로 선행연구에서 공통으로 사용된 형태, 색, 움직임, 깊이를 인터뷰영상에 적합하게 유형화하였다. 분석결과 시사다큐멘터리의 인터뷰는 취재원보호를 위한 영상표현이 과반수에 가까웠으며, 샷의 형태는 버스트샷과 함께 클로즈업을 많이 사용되었다. 즉흥적 인터뷰가 많아서 현장 조명을 이용하여 색을 만들었고, 고정된 촬영보다는 핸드헬드 기법을 이용한 움직임이 나타났다. 또한 와이드렌즈의 사용으로 화면의 깊이감은 나타나지 않았다.

The difference in the breeding programs and population history may have diversely shaped the genomes of Korean native cattle breeds. In the absence of phenotypic data, comparisons of breeds that have been subjected to different selective pressures can aid to identify genomic regions and genes controlling qualitative and complex traits. In this study to decipher genetic variation and identify evidence of divergent selection, 3 Korean cattle breeds were genotyped using the recently developed high-density GeneSeek Genomic Profiler F250 (GGP-F250) array. The three Korean cattle breeds clustered according to their coat color phenotypes and breeding programs. The Heugu breed reliably showed smaller effective population size at all generations considered. Across the autosomal chromosomes, 113 and 83 annotated genes were identified from Hanwoo-Chikso and Hanwoo-Heugu comparisons, respectively of which 16 genes were shared between the two pairwise comparisons. The most important signals of selection were detected on bovine chromosomes 14 (24.39-25.13 Mb) and 18 (13.34-15.07 Mb), containing genes related to body size, and coat color (XKR4, LYN, PLAG1, SDR16C5, TMEM68, CDH15, MC1R, and GALNS). Some of the candidate genes are also associated with meat quality traits (ACSF3, EIF2B1, BANP, APCDD1, and GALM) and harbor quantitative trait locus (QTL) for beef production traits. Further functional analysis revealed that the candidate genes (DBI, ACSF3, HINT2, GBA2, AGPAT5, SCAP, ELP6, APOB, and RBL1) were involved in gene ontology (GO) terms relevant to meat quality including fatty acid oxidation, biosynthesis, and lipid storage. Candidate genes previously known to affect beef production and quality traits could be used in the beef cattle selection strategies.

In textile industry, needs for various weave drafts have been increased to produce high qualified textile goods. One of disadvantages of traditional textile industry was spending time and money on manual sampling. Nowadays, however, weave draft design and sampling using CAD programs reduce these consumption efficiently. Therefore, this study aimed to provide high qualified woven fabrics by weave draft designs influenced by geometric patterns. First, We analyzed geometric patterns, except for dot, stripe, and checks, in fashion collections from 2009 to 2014 S/S. Then, based on these analyses, design concepts were decided. Third, weave drafts influenced by geometric patterns were designed with weave CAD program, TEX PRO 10.0 by Youngwoo CNI inc. Forth, We simulated fabrics woven by new drafts using CAD programs, depending on fibers, yarns, density of woven, colors, and finishes. Unclassified geometric patterns would be expressed by small size patterns that influenced by retro moods, square patterns with various color variation, zigzag lines, and pieces of puzzles. Three design concepts were decided as greenness, neoclassic, and romantic chic. Thus, geometric patterns for printing were created as drafts for general looms, and one repeat of each draft were provided. According to the design concepts, we designed 13 fabrics with 4 geometric patterns weaving drafts. All Drafts were designed with CAD programs. Finally, same drafts were simulated as woven fabrics for both S/S and F/W seasons by changing each element, such as fiber, yarns, density, colors, and finishes.
