Three-dimensional (3D) object retrieval from user-drawn sketch queries is one of the important research issues in the areas of pattern recognition and computer graphics for simulation, visualization, and Computer Aided Design. The performance of content-based 3D object retrieval system depends on the availability of effective descriptors and similarity measures for this kind of data. In this paper, we present a sketch-based 3D object retrieval system by extracting a hybrid edge descriptor which is robust against rotation and translation. The experimental results which are based on HTML5 and WebGL show that proposed sketch-based 3D object retrieval method is very efficient to search and order the 3D objects according to user's intention.

Objectives : Kaempferia parviflora Rhizome is black ginger indigenous to Laos and Thailand. It has been used as a folk medicine to improve blood flow and promote vitality and longevity with good health and well being. For these reasons, Kaempferia parviflora Rhizome has been focused on developing it as a food or food supplement. In addition, Kaempferia parviflora Rhizome could be under consideration of new prescription based on its characteristic compounds, polymethoxyflavonoids. However, it needs to be certified as safe before it can be used. Here, a single-oral toxicity test and safety classification was carried out to identity acute information of the toxicity of Kaempferia parviflora Rhizome powder and to make sure of its safety in clinical applications. Methods : Test substance was orally administered to male and female SD-rat at dose levels of 5000 mg/kg to estimate approximate lethal dose(ALD). Based on the acute information of the toxicity, the safety classification was estimated using the HED(human equivalent dose)-based MOS(margin of safety). Results : At 14 days after treatment with test substance. there were no of test substance related with mortalities and clinical signs. In addition, no changes in the body or organ weights and no gross or histopathological findings were observed. Thus, the ALD of Kaempferia parviflora Rhizome powder was considered over 5,000 mg/kg in both female and male mice. Conclusions : Based on the single oral toxicity test using the highest and limit dose, 5,000 mg/kg and the decision guideline for safety classification based on HED-based MOS, it was estimated that Kaempferia parviflora Rhizome powder is classified as "Specified class B" indicating that clinical dose is not limited to patients as safe as food.

The roots of Dipsacus asper are used in traditional Chinese medicine as an analgesic, enhancement of liver activity, an anti-inflammatory agent and the treatment of fractures. In order to investigate the antioxidative activity, Dipsaci Radix was extracted with MeOH and fractionated with $CHCl_3$, EtOAc, BuOH and water. MeOH ex. and its solvent fractions were determined on the free radical scavenging activity by DPPH method and antioxidative activity on low density lipoprotein oxidation. The EtOAc and BuOH fractions showed antioxidative activities and from their fractions, two compounds were isolated and identified as hederagenin 3-O-${alpha}$-L-arabino pyranoside (compound 1) and O-${\alpha}$-L-arabinopyranosyl hed-eragenin 28-O-${\beta}$-D-glucopyranosyl ($1{\to}6$)-${\beta}$-D-glucopyranosyl ester (compound 2). Saponin glycoside, compound I showed anti-oxidative activity.

We have studied the relation between Ca$^{2+}$-ATPase and trigger peptidase(TPase) which are membeane protein well known as their significant role for signal transduction of mating pheromone in heterobasidiomycetous yeast. Rhodosporidium toruloides. We found out that there were Ca $^{2+}$-ATPase and TPase together in isolated calmodulim binding protein(CBP), usion calmodulin affinity column chromatography after solubilization of mation type a cell membrane protein, and that the dependence of enzyme activity of both the enzymes on Ca$^{2+}$, phospholipid and nonionic detergent are similar. However, Ca$^{2+}$-ATPase hed quite absolute dependence on calmodulin and, on the other hand, TPase didn't have any dependence. Judging from the fact that there are both enzymes in CBP which the dependence of calmodulin are quite different, we found out that both enzymes were made to their compound and existed in mating type a cell membrane.

The purpose of this study is to classify the patterns of consumption deprivation and to compare the level of consumption deprivation by them. For empirical analysis, this study used the data on 563 households in the city of Inchon collected by the researchers through interviews. The statistical methods used in this study were cluster analysis, oneway ANOVA, and crosstabs. four clusters were classified: 'Overall satisfied Pattern (OSP)', 'Food satisfid with Others deprived Pattern (FS-ODP)', Food Extremely deprived with Food Deprive Pattern (HED-FDP)'. Those I FED-HSP tended to be old aged, and those in GED-FDP tended to be urban unstable workers. The results imply that welfare policy for urban poor households should be differentiated by the characteristics of consumption of each pattern of consumption deprivation.

In this paper, we propose a new scheme for automatic segmentation of the liver in CT images. The proposed scheme is carried out on region of interest(ROI) blocks that include regions of the liver with high probabilities. The ROI approach saves unnecessary computational loss in finding the accurate boundary of the liver. The proposed method utilizes the composition of multi-size morphological filters with a prior knowledge, such as the general location or the approximate intensity of the liver to detect the initial boundary of the liver. Then, we make the gradient image with the weight of the initial liver boundary and segment the liver legion by using an immersion-based waters hed algorithm in the gradient image. finally, the refining process is carried out to acquire a more accurate liver region.

Ectodermal dysplasia is a genetic disorder in which various clinical manifestations involve two or more of the differentiated tissues of the ectoderm. Facial deformity, which is frequently associated with ectodermal dysplasia, appears in the form of cleft lip or cleft palate, especially in the middle facial area.Cleft and tooth defects result in decreased alveolar bone development.This leads to severe skeletal incongruity. Facial features include frontal protrusion, malar bone hypoplasia, flat nose, mandibular prominence and long lower facial height. This clinical report presents treatment including orthognathic surgery of a patient with Hypohidrotic Ectodermal dysplasia with cleft palate.
