  • The origin and description of the Herba Plantaginis was contemporarily analyzed (family names, scientific names, target regions, preparation, etc.) by comparison to enormous literature in addition to the external features written in the existing books on traditional Korean medicine. Also, galenical description were analyzed in connection with external morphology, internal morphology, microscopy and five senses. The official documents and ancient documents of other countries were reviewed. The technical books on herbage, published in the country and other countries, were compared with each other. Also, on-the-spot surveys were made to learn specialists' know-how. The description of the collected drugstuffs were analyzed in connection with external morphology (size, color, etc.), internal morphology and microscopy. The results of this study can be applied to the publicity and education of galenical test agencies; the effective management of foods and drugs; the improvement of public medical service; the publicity of galenical safety.

  • 시작점과 끝점의 y축 분할표를 이용하여 체인코드 표현의 영상을 복원하는 빠른 방법을 제안하였다. 제안된 참조표는 시작점과 끝점이 구분되어지며 이를 이용해 체인코드 표현을 두개의 y축 분할표로 변환한다. 이 방법은 순서정렬 해야할 y축 분할표의 요소수가 반으로 줄어 처리 속도가 Shih의 방법보다 훨씬 빠르다. Shih의 방법과 처리 속도를 비교하였다.

  • Coolia santacroce is a newly described epibenthic dinoflagellate species collected from the U.S. Virgin Islands. The original description indicates this species is unique from others in the Coolia monotis complex due to the relative size of the apical pore complex, broad range of pore sizes, and ribosomal DNA. The original description was done based on the isolation and cultivation of one isolate of the organism. In this study, we report three more isolates of Coolia santacroce collected from the Bahamas. Morphological observations were made using scanning electron microscopy that do not correspond to those from the original description, indicating the variability of the morphological features. However, analysis of the D1 / D2 regions of the large subunit rDNA places the three strains in a strongly supported monophyletic clade with the type specimen.

  • Three freshwater ciliates, Lembadion lucens (Maskell, 1887) Kahl, 1931, L. bullinum ($M{\ddot{u}}ller$, 1786) Perty, 1849, and L. magnum (Stokes, 1887) Kahl, 1931, belonging to the genus Lembadion Perty, 1849 are newly reported from Korea with detailed descriptions and illustrations based on live observation and protargol impregnation. Lembadion lucens is characterized by following characteristics: $52-91{\times}33-64{\mu}m$ body size in vivo; ovoid and slightly asymmetric body shape; 27-49 somatic kineties; and 55-80% of whole pellicle covered with meridional lines with rectangular meshes in posterior portion. Lembadion bullinum is distinguishable from its congeners by its body size of $110-130{\times}60-73{\mu}m$ in vivo; ovoid body shape; oral aperture occupying about four-fifths of ventral side; 48-55 somatic ciliary rows; meridional lines with rectangular meshes except anterior portion (about 16% of body) on pellicle. Lembadion magnum is also characterized by its body size of $70-90{\times}37-50{\mu}m$ in vivo; obliquely asymmetric anterior end of body; oral aperture occupying about more than four-fifths of ventral surface, and opened longitudinally entire ventral surface; 45-61 somatic ciliary rows; meridional lines without rectangular meshes on whole pellicle of body. The present study is the first description of the genus Lembadion from Korea.

  • This study was initiated to investigate (1) whether consumers preferred a specific garment size labeling system and (2) whether consumer's demographic characteristics, clothing behavior, and body size affect their preference of size labeling systems. The survey of consumer's preferences for five size labeling systems included 443 women with 20 to 64 years of age. The result of the survey showed that the subjects' preferences of five size labeling sysems were different significantly. Subjects strongly preferred the old system rather than the revised systems. The subjects least preferred the system with pictogram(system D) and the system with description of the measuring methods of te control dimensions (system E). The subjects/ preference for various garment size labeling systems was different depending on their resident area, educational level, and body size. The garment size labeling system with more information on body measurements (system C) was preferred by the subjects living in the metro city area or subjects having difficulties on purchasing ready-to-wear garments giving reasonable fit. The simplest size labeling system (system A) was strongly preferred by the subjects of low educational level, or the subjects living in the small city.

  • At the time when nanostructured materials (NSMs) are becoming a major focus of materials research, the attention of researchers is turning more to their mechanical performance. In contrast with conventional coarse grained materials, which are either strong or ductile, but rarely both at the same time, it is expected that with NSMs both high strength and ductility can be achieved and confirmed by several experimental studies. In spite of the significant interest and efforts in the mechanical properties of NSMs, deformation mechanisms during plastic deformation as well as elastic deformation are not well established yet. In this talk, the deformation mechanisms of NSMs under various grain sizes, temperatures and strain rates were investigated. It is based on recent modelling that appears to provide a conclusive description of the phenomenology and the mechanisms underlying the mechanical properties of NSMs. Based on the theoretical model that provides an adequate description of the grain size dependence of elasticity and plasticity covering all grain size range from coarse down to the nanoscale, the tensile deformation response of NSMs, especially focusing on the deformation mechanisms was investigated.

  • Nowadays, many commercial ERP products, such as Oracle, SAP, and Baan, etc, are designed based on large-scaled companies. It is difficult for small and medium-size companies with weakness in budgets and resources(e.g., human, organization, technique, and so on) to use them as it was. So, new ERP system need to be provided for small and medium-size companies. In this paper, we model and provide a conceptual ERP model for small and medium-size companies by using "4+1 View" architecture model of Unified Modeling Language(UML). The conceptual ERP model consists of five subsystems: Manufacturing, Sales, HumanResource and Payroll, Accounting, and Trading. Especially, we describe the conceptual ERP model focusing on "Manufacturing" subsystem by using several diagrams of UML. By using the conceptual ERP model, the ERP system′s developers of small and medium-size companies can obtain many benefits: improving the efficiency of software developing process and helping user requirements gathering and description of ERP system′s nonfunctional aspect as well as functional aspect.

  • In this paper, we propose the cross-section processing method which is simple in describing the SHGC of objects in a range image and which can describe the SHGC of occluded objects for the recognition of 3D objects. This method produces the cross-sections of an object along the assumed axis of the SHGC and describes the SHGC of the object by processing the produced cross-sections of the object using $\psi$ -S curves with invariant properties in position and size. Our method is simple in a process and can descirbe the SHGC of partially occluded objects because it uses range images with 3-D informations of objects without matching contours of objects with a model base. Thus it is a useful description method of a range image for the recognition of 3D objects shaped in SHGC form and we proved the usefulness of it in experiments.

  • Multiple Description (MD) coding is a promising alternative for the robust transmission of information over error-prone channels. Lattice vector quantization (LVQ) is a significant version of MD techniques to design an MD image coder. However, different from the traditional 2D texture image, the 3D depth image has its own special characteristics, which should be taken into account for efficient compression. In this paper, an optimized MDLVQ scheme is proposed in view of the characteristics of 3D depth image. First, due to the sparsity of depth image, the image blocks can be classified into edge blocks and smooth blocks, which are encoded by different modes. Furthermore, according to the boundary contents in edge blocks, the step size of LVQ can be regulated adaptively for each block. Experimental results validate the effectiveness of the proposed scheme, which show better rate distortion performance compared with the conventional MDLVQ.
