  • When data is transmitted over an unreliable channel, the error of the data packet may result in serious degradation. The multiple description coding (MDC) can solve this problem and save transmission costs. In this paper, we propose a deep multiple description coding network (MDCN) to realize efficient image compression. Firstly, our network framework is based on convolutional auto-encoder (CAE), which include multiple description encoder network (MDEN) and multiple description decoder network (MDDN). Secondly, in order to obtain high-quality reconstructed images at low bit rates, the encoding network and decoding network are integrated into an end-to-end compression framework. Thirdly, the multiple description decoder network includes side decoder network and central decoder network. When the decoder receives only one of the two multiple description code streams, side decoder network is used to obtain side reconstructed image of acceptable quality. When two descriptions are received, the high quality reconstructed image is obtained. In addition, instead of quantization with additive uniform noise, and SSIM loss and distance loss combine to train multiple description encoder networks to ensure that they can share structural information. Experimental results show that the proposed framework performs better than traditional multiple description coding methods.

  • Aural archival description has been rarely discussed, although it is one of the important process in managing and using aural archives. Aural archives not being cataloged are difficult to access; moreover they require tools and a lot of time to search appropriate records. This study concerning characteristics of archival description and aural archives analyzed rules for aural archival description in United Kingdom, Canada and United States of America Comparing and analyzing rules, a rules for aural archival description in Korea was proposed and arranged into eight areas modified from seven areas of ISAD(G). This study focused on developing rules for description covering all aspects of aural archives in Korea. The rules for aural archival description will offer a base of Korean Rules for Archival Description and building aural archival databases.

  • Archival description in archives has an important role in document control and reference service. Archives has made an effort to do archival description. But we have some differences and problems about a theory and practical processes comparing with advanced countries. The serious difference in a theory is that a function classification, maintenance of an original order, arrangement of multi-level description are not reflected in practical process. they are arranged in shelves after they are arranged by registration order in a unit of a volume like an arrangement of book. In addition, there are problems in history of agency change or control of index. So these can cause inconvenience for users. For improving, in this study we introduced the meaning and importance of arrangement of description, the situation and problem of arrangement of description in The National Archives, and a description guideline in other foreign countries. The next is an example for ISAD(G). This paper has chapter 8, the chapter 1 is introduction, the chapter 2 is the meaning and importance of arrangement of description, excluding the chapter 8 is conclusion we can say like this from the chapter 3 to the chapter 7. In the chapter 3, we explain GOVT we are using now and description element category in situation and problem of arrangement of description in Archives. In the chapter 4, this is about guideline from Archives in U.S.A, England and Australia. 1. Lifecycle Date Requirement Guide from NARA is introduced and of the description field, the way of the description about just one title element is introduced. 2. This is about the guideline of the description from Public Record Office. That name is National Archives Cataloguing Guidelines Introduction. We are saying "PROCAT" from this guideline and the seven procedure of description. 3. This is about Commomon Record Series from National Archives of Australia. we studied Registration & description procedures for CRS system. In the chapter 5, This is about the example which applied ISAD to. Archives introduce description of documents produced from Appeals Commission in the Ministry of Government Administration. In the chapter 6, 7. These are about the problems we pointed after using ISAD, naming for the document at procedure section in every institution, the lack of description fields category, the sort or classification of the kind or form, the reference or identified number, the absence description rule about the details, function classification, multi-level description, input format, arrangement of book shelf, authority control. The plan for improving are that problems. The best way for arrangement and description in Archives is to examine the standard, guideline, manual from archives in the advanced countries. So we suggested we need many research and study about this in the academic field.

  • Incremental forming is a cold working process in which a small part of the material is being deformed and the area of local deformation is moving over the entire material. In this paper, we study description schemes to perform finite element analysis for the incremental forming. The selected description schemes to examine are the Lagrangian description and the arbitrary Lagrangian-Eulerian (ALE) description. The sliding boundary scheme coupled with ALE is also examined to overcome the distortion problems of elements on the contact surface. Results show that the ALE description with the sliding boundary scheme is most favorable in overcoming the distortion of elements. This description leads to make the simulation continued to the final stage of the incremental forming. On the other hand, the Lagrangian description as well as the original ALE description makes the elements much distorted and the analysis is stopped long before arriving at the final shape of deformation.

  • Variability of the software product line that differentiates member products within a product line must be described with precise meaning and visualized so as easy to select. Moreover, it should be easy to manage. Variability description approaches can largely be divided into two approaches, integrated variability description approach and orthogonal variability description approach. Orthogonal Variability Description Language (OVDL) was developed for clear and precise description of variability without ambiguity. This paper validates the variability description capability of OVDL by translating the variability models of Inter-Working Function (IWF) product line described by using Orthogonal Variability Model (OVM) notations into variability descriptions in OVDL.

  • This Study is to propose the archival description in accordance with the paradigm shift of the archival science. The academic world of archival science in North America treated the electric record in 1990 and the authenticity of electric record in the beginning of 2000, the flow of Study recognizing the microscopic and the cultural discussion appeared recently. This may be called the paradigm shift of archival science. This may be according to the influence of the informatization and the technology. However, the community archives, the everyday life archives recognizing the microscopic and the cultural discussion, etc. Namely, the everyday life, the village, the community archives are the effort to leave the excluded and the neglected voices from the existing discussion of archival science on record. However, the currently existing methodology to archive the community archives based on the perception of these switched recognition is limited. Especially the description of the various standards being used in the public territory is being adapted as it is. The characteristic and the individuality of the community and the community archive cannot be reflected through the archival description standard. We should understand the community archive in accordance with the paradigm shift, need the archival description method capable of expressing this suitably. The post-standard not the existing archival description method has been necessary. This should be carried out together in accordance with the view point of the paradigm shift and the view point of the objective and the direction of community. Hence, first the archival description and the paradigm shift have been examined theoretically and the archival description of community archive being operated currently has been analyzed. The archival description is to be proposed in accordance with the paradigm shift capable of calling 'the archival description of Korean Human Right' by pointing out the limit of archival description standard through the analysis and further by investigating the archival description of the fraternity archive project.

  • Shape description is an important and fundamental issue in content-based image retrieval (CBIR), and a number of shape description methods have been reported in the literature. For shape description, both global information and local contour variations play important roles. In this paper a new included-angular ternary pattern (IATP) based shape descriptor is proposed for shape image retrieval. For each point on the shape contour, IATP is derived from its neighbor points, and IATP has good properties for shape description. IATP is intrinsically invariant to rotation, translation and scaling. To enhance the description capability, multiscale IATP histogram is presented to describe both local and global information of shape. Then multiscale IATP histogram is combined with included-angular histogram for efficient shape retrieval. In the matching stage, cosine distance is used to measure shape features' similarity. Image retrieval experiments are conducted on the standard MPEG-7 shape database and Swedish leaf database. And the shape image retrieval performance of the proposed method is compared with other shape descriptors using the standard evaluation method. The experimental results of shape retrieval indicate that the proposed method reaches higher precision at the same recall value compared with other description method.

  • The purpose of this study was to examine the development of detailed description for drawing houses according to the shapes of lines, and dimensions of space from 4 to 5 years-old children. Participants were 76 children from a daycare center in Busan, Korea. Each child was asked to draw 4 different houses according to the shapes of lines and dimensions of space, such as: straight lines and 2-dimensional pictures straight lines and 3-dimensional Models, curved lines and 2-dimensional pictures and curved lines and 3-dimensional models. The children's drawings were scored based on a "detailed description rating table" which consisted of 10 items. Summarizing the overall results, first, 5 year-olds scored significantly higher than 4 year-olds in the detailed description of 4 different house models. Second, the houses with straight lines scored significantly higher than those with curved lines in the detailed description. Third, there were no significant differences between 2-dimensional houses and those of 3-dimensional models in the detailed description. These results suggest that the detailed description of young children's drawing is developed as children grow older, and drawing with straight lines are earlier developed than curved lined drawings.
