This study conducted comparative analysis of cataloging descriptions and rules in KCR 4 and CCR 2, as follows, for the purpose of seeking understanding of classical materials cataloging rules and networking of oriental historical data cataloging (bibliographical descriptions). First, to compare the general rules, the objects of descriptions and composition of descriptions, recording order, and punctuation and information source of descriptions were analyzed. As a result, KCR 4 is more detailed in terms of author role identifications and information source regulations and CCR2 is more detailed in terms of regulations related to printing and publications and serial publications. Second, to compare the details, the main titles and liability indications, edition details, publication details and format details, and note details. As a result, regarding the description of edition type and publication details, KCR4 has detailed regulations and CCR2 has characteristic summary in terms of note details.

Since the year 2000, the need for an improvement of archival descriptions has been an increasing issue, due to the growing usage and amount of archival materials. Unlike the development of descriptions for paper records, however, the technological development and research for moving image descriptions has been limited due to its diversity and specificity. This research investigated the current status and the specificity of the moving image descriptions and also examined major international archival description cases. In-depth interviews with archival professionals were also conducted. Based on the findings, this study suggested the need for redefinition of and continuous research on the fundamental values of moving image information, moving image description and management based on digilog view points, the development of user-centric description and search aides, the creation of moving image values using a relevant information management system, and the improvement of moving image description elements throughout the life-cycle of the material.

The purpose of this study is to analyze the concept of igneous rock textures and to uncover incorrect descriptions regarding the concept found within high school Earth Science II course seventh curriculum textbooks. Based upon this analysis suggestions will be made so as to improve descriptions regarding the concept of igneous rock texture. At least some incorrect descriptions regarding igneous rock texture were found in all the textbooks examined. Textures of volcanic rocks are described as being either fine-grained and glassy or porphyritic, while those of plutonic rocks are described as hollocrystalline, granular, coarse-grained or equigranular. These descriptions may contribute to forming and/or reinforcing misconceptions about both the classification criteria for, as well as the general concept of igneous rock textures. Therefore, some improvement schemes for the classification of igneous rock textures have been suggested. These schemes suggest that volcanic rocks be classified as either aphanitic or porphyritic, while plutonic rocks be classified as phaneritic, hollocrystalline or equigranular according to granularity, crystallinity, and both the absolute and relative sizes of the crystals within the rock.

Phenotyping is a major issue for wheat agriculture to meet the challenges of adaptation of wheat varieties to climate change and chemical input reduction in crop. The need to improve the reuse of observations and experimental data has led to the creation of reference ontologies to standardize descriptions of phenotypes and to facilitate their comparison. The scientific literature is largely under-exploited, although extremely rich in phenotype descriptions associated with cultivars and genetic information. In this paper we propose the Wheat Trait Ontology (WTO) that is suitable for the extraction and management of scientific information from scientific papers, and its combination with data from genomic and experimental databases. We describe the principles of WTO construction and show examples of WTO use for the extraction and management of phenotype descriptions obtained from scientific documents.

This paper presents the design and implementation of SVSIM (Sogang VHDL SIMulator), a multi-level VHDL simulator, designed for the construction of an integrated VGDL design environment. The internal model of SVSIM is the hierarchical C/DFG which is extended from C/DFG to include the network hierarchy and local/glabal control informations. Hierarchical network is not flattened for simulation, resulting in the reduction of space complexity. The predufined/user-defined types except for the record type and the predefined/user-defined attributes are supported in SVSIM. Algorithmic-level descriptions can be siumlated by the support of recursive procedure/function calls. Input stimuli can be generated by command script in stimuli file or in VHDL source code. Experimential results show SVSIM can be efficiently used for the simulation of the pure behavioral descriptions, structural descriptions or mixture of these.

This paper is to find and to suggest alternative ways of description on function chapters in the middle school mathematics so that the descriptions be more closely related to daily life. The research has two phases: one for belief on the usefulness, the other for cognitive ability to solve the practical problems. Results are as following. 1. Most descriptions of corresponding chapters have emphases on the usefulness of functions so as to enhance beliefs on the use of functions. 2. Most practical functions contain expressions of large constant term and large coefficients in magnitude while those are not in the descriptions of tektbooks, especially in case of using ruled papers. 3. For quadratic functions, most students do not detect the degree of the function from the data presented by pairs of values of x and y. And those are not dealt with in most of textbooks, which are given in the MIC textbook.

One of the inherent problems in constructing the sign language dictionary is how to make retrieval and comparison operations on the visual database of signs. This paper describes a retrieval method, especifically for Japanese signs. This method has a useful capability for flexible retrieval of the sign from a bilingual dictionary. Our method can retrieve similar signs to the given input. The retrieval mechanism is essentially based on similarity between the given verbal description and verbal descriptions in a retrieval database. The similarity measure of verbal descriptions can be considered as the approximations for the similarity of sign motion images. As a results of our experiment, the success ratio of the retrievals is 96% in averages.

This research is the palynotaxonomic revision to clarify palynological descriptions and relationships of taxa in Korean Verbenaceae. To do this, morphology, size, sculpture and aperture of pollen grain were investigated with scanning electron microscope. As a result, palynological key as to 5 genera 10 species drawn up. Palynological descriptions of Callicarpa dichotoma, Callicarpa mollis, Callicarpa chejuensis, Vitex chinensis and Caryopteris incana are near completion at first. Vervena officinalis are newly described and descriptions of Callicarpa japonica, Clerodendrum trichotomum, Vitex rotundifolia and Caryopteris divaricata are corrected. Palynological data of Korean Verbenaceae is useful to intrageneric relationships. Namely, as to genus Callicarpa, C. dichotoma and C. japonica are considered to be more advanced than C. mollis and C. chejuensis. As to genus Caryopteris, C. divaricata is more advanced than C. incana.

Multiple Description Coding(MDC) is a technique used to obtain two or more (often correlated) descriptions of a source, which are transmitted over different channels to receiver. Two descriptions of the source support two levels of reconstruction quality. When all the descriptions are received and used in the reconstruction, the source should be reconstructed with acceptable quality. In this work, we consider Multiple Description Scalar Quantizer(MDSQ) to wavelet transform domain. Conventional MDSQ schemes in wavelet domain considered description with equal weights at each sub-bands after quantization. But each sub-bands is unequal contribution to whole image quality. Therefore, we experiment the multiple description with unequal weight in each sub-bands.

Examination of the original descriptions of genera placed within the family Oposthorchiidae has revealed that only 33 of the original 43 genera are valid members of this family Further study of these descriptions should also reveal that many of the subfamilies are also invalid. With reference to the original descriptions of these genera, and subsequent literature, a brief survey of the family has been compiled. Information on the spectrum of definitive hosts that these helminths parasitize is provided, as well as information on the life cycles, geographic distribution, and socioeconomic impacts of the family. More in-depth information is given on those species that are of particular medical importance; namely, Clonorchis sinensis, Opisthorchis viverrini and O. felineus. The final aims of this review are to provide information on the entire genera of the family Opisthorchiidae, which will aid understanding of the phylogenetic relationships not only within the family, but also within the Class Trematoda.
