DIBR (Depth Image Based Rendering) is a multimedia technology that generates the virtual multi-view images using a color image and a depth image, and it is used for creating glasses-less 3-dimensional display contents. This research describes the effect of depth accuracy about the objective quality of DIBR-based multi-view images. It first evaluated the minimum depth quantization bit that enables the minimum distortion so that people cannot recognize the quality degradation. It then presented the comparative analysis of non-uniform domain-division quantization versus regular linear quantization to find out how effectively express the accuracy of the depth information in same quantization levels according to scene properties.

Modern figurative work is designed to have more creativity and characteristic traits by pure thought of the formative ceramic arts. In compliance with the demand which is various the design development could be satisfied an individuality and a taste is become accomplished. In this view, this study looks over expressive aspect of Cubism to present partition as a independent formative ceramic arts is able to contribute emotionally to our whole lives. In this procedure, this work is produced to express a three-dimensional effect and a spatial effect, approaching a figurative side. This is to overcome the limitation of Cubism art expressed in a two-dimensional surface in spite of its multi-dimensional observation of a given object. Accordingly, this study tries approaching pre-understanding of expressive aspect of Cubism which was the important turning-point in 20c art and expansion of the modern ceramic art field before producing the work. This study shows the possibility to become a creative and practical ceramic art work, approaching the new point of view breaking from the established conception. Consequently, the field of ceramic art could be expanded to a part of modern ceramic art as an object of study in art of life.

This paper analyses meta-data systems for serials in order to provide the fundamental infrastructure for serials-sharing systems based on semantic interoperability. According to the primitive features of serials information, meta-data for serials are classified into 3 main subsystems: serial identification Information, serial bibliographic information and serial holding information. The serial identification information that play the important role of the primary key in library management systems should be refined to accommodate serials with digital formats. Although MARC formats have been commonly used for the description of serial bibliographic information, a new meta-data format for serial bibliographic information that harmonize with the abundance of meta-data elements in MARC and the simplicity of DCMI. For serial holding information, the newly proposed standards such as ANSI/NSIO Z39.50 are adequate to grasp the varieties of serial holding patterns. It should be able to differentiate the level of description by means of the types of serial information services. As the current computing technology generally uses XML for the representation and Process of information, the meta-data system for serials should be based on XML.

With the increasing interest on K-fashion all over the world, it's the important time to create the items which can express the unique identity of Korea for promoting the globalization of Korean fashion. Accordingly, this study aims to suggest the modern applicability of traditional patterns by designing the bags using the Dancheong patterns(traditional multi-colored decorative painting) which can effectively express Korean images in a variety of shapes and definite visual features and then expand the scope of fashion items. To this end, this study concentrated on expressing the Dancheong patterns to fit to the modern fashion trends by re-interpreting them. The bag was designed using the laser cutting technique, without weaving or digital printing, to imbue the technical emotion and 3D effect to the patterns. In accordance with the analysis results, the features of patterns could be delicately expressed around the shaping and structuring method in terms of the design, and the scope of design for leather goods could be expanded using the laser cutting in technical aspects. For the industrial aspects, it is required to develop differentiated goods expressing the unique emotion of the Korean for globalization of Korean design.

After platform changed from PC-based internet to mobile, SNS became new interactive media which relaces face-to-face interaction. the SNS users have already begun to recognize SNS as daily necessity. SNS market has been subdivided. In other words, SNS has entered into a period of vertical SNS that focus on contents and specific target. Therefore, It is necessary to analyze users for SNS planners. For this reason, analyzing why office workers who have the most powerful purchasing power use SNS is meaningful for SNS planners. Therefore, in this study, we analyzed the reasons for using SNS of office workers by studying relationship among office workers' stress, social support, self-expression and the use of SNS. As a result, the use of SNS has a significantly positive correlation with social support and self-expression. The self-expression in the SNS is not associated with stress, but rather it is the characteristics of the office workers. However the social support in the SNS affects to stress.

This study will examine the visual composition by which Secretly Greatly, in a circumstance that even the good original Manhwas or Webtoon have not made a hit on the market until now, could attract the spectator, in other word, illustrate the analogousness of the images through analysing visual texts. The study draw, first of all, a meaning of the box office performance caused by analogousness of image, that is similarity between the webtoon and film. In addition, the study will come up with an answer to the question that the webtoon, not in a temporary trend but in a sustainable form, can make itself develop. For this, the study suggests a meaning, worth and importance of the transformation, analysing visual components of a webtoon to film adaptation, Secretly Greatly. It primarily ranges over visual components, mise-en-scène identified with its expression formula, frame to frame changes and colour and tone. The examination sets the cinema's visual expression manner against the webtoon's on their concrete components: the size of scene, movement, color and tone, narrative condition and its background, spatial composition and depth, contrast, expression manner and disposition manner.

In general, image-based virtual environment is represented by panoramic images created by image mosaic algorithm. The cylindrical panoramic image supports the fixed-viewpoint navigation due to the constraints of construction. Shum proposed concentric mosaics to allow users to navigate freely within a circular area[10]. It is constructed by a sequence of images which is acquired from a regularly rotating camera. Concentric mosaics technique, proposed by Shum, is considered as 3D plenoptic function which is defined three parameters : distance, height and angle. In this paper, we suggest an effective method for creating concentric mosaics, in which we first align a set of strip images on the cylinder plane and stitch the aligned strips to build a panoramic image. The proposed method has no constraints such as regular panning motion of camera. Furthermore, our proposed method minimizes the use of interpolation image to create a novel view images from the concentric mosaics. It allows the result image on a novel view to have better quality with respect to the number of input images.

유역모형을 통해 우심하천을 제시하는 방법은 많은 노력과 시간이 요구되는 경우가 많다. 본 연구에서는 국가배출부하량 자료를 사용하여 간단하게 오염원별/오염물질별 수질 관리가 요구되는 하천을 선정하는 방법을 제시하고, 우심하천을 선정하였다. 적용 유역은 한강 수계에서 가장 복합한 댐 유역인 충주댐 유역으로 결정하였다. 충주댐 유역의 소유역별 배출부하량을 활용해 하천 관점의 배출부하량을 산정하였다. 하천 관점의 배출부하량 (Stream Total Loads, STL로 명명)은 임의의 하천으로 유입되는 모든 소유역의 배출부하량 합계를 면적 합계로 나누어 산정하는 방법이며, 임의의 하천 지점에서 상류의 모든 소유역이 포함된 단위면적당 배출부하를 의미한다. 따라서 댐 유역 말단의 STL은 유역 전체의 단위면적당 배출부하로 표현되며, 유역 전체의 STL보다 높은 소유역이 연결된 하천을 댐 호소 관점에서 볼 때 관리가 필요한 하천이라 할 수 있다. 댐 유역 말단의 STL은 점오염원-BOD 0.617 kg/km²/day, 점오염원-TP 0.038 kg/km²/day, 비점오염원-BOD 2.909 kg/km²/day, 비점오염원-TP 0.237 kg/km²/day로 산정되었다. 점오염원에 대한 BOD 관리하천은 창리천, 장평천, 지장천하류 등 15개 소유역, TP 관리하천은 주천강시점, 창리천, 주천강상류 등 20개 소유역으로 나타났다. 비점오염에 대한 BOD 관리하천은 주천강시점, 장평천, 제천천하류 등 13개 소유역, TP 관리하천은 주천강시점, 장평천, 주천강상류 등 16개 소유역으로 나타났다. 또한 전체 배출부하에 대한 비점오염원의 배출부하비는 BOD 82.5%, TP 86.2%로 점오염원보다 높았다. 따라서 우선 관리 대상 하천은 TP 비점오염원, BOD 비점오염원, TP 점오염원, BOD 점오염원 순으로 계획될 필요가 있다. 향후 유역 모델링을 수행하고, STL 산정 결과와 비교하여 우심 하천 선정에 대한 적합성을 평가할 예정이다.
