In the Gen-2 Q-algorithm, the values of weight C, which is the parameter for incrementing or decrementing the slot-count size, are not optimized in the standard. However, the standard suggests that the reader uses small values of C when the slot-count is large and larger values of C when the slot-count is small. In this case, if the reader selects an inappropriate weight, there are a lot of empty or collided slots. As a result, the performance will be declined because the frame size does not converge to the optimal point quickly during the query round. In this paper, we propose a scheme to select the weight based on the slot-count size of current query round. Through various computer simulations, it is demonstrated that the proposed scheme achieves more stable performances than Gen-2 Q-algorithm.

Introduction The effects of Bojungikkitang on the immunosuppression induced by methotrexate in rats were investigated in this experiment. The multiple parameters of immunity assessed in. each rats includes the rate of body weight loss, weight changes in thymus, spleen and axillary lymphnode. The number of lymphocyte and CD4+ T cell count in blood, thymus, spleen and axillary lymphnode were also measured. Methodology Male Sprague-Dawley rats were chosen as an experiment object and were divided into 3 groups by a random selection. Each group consisted 6 rats. The normal group didn't receive any treatment. The control group was administered methotrexate for 4 days. The sample group was administered with both Bojungikkitang and methotrexate for 4 days. The dosage of medication was 2cc/day, 1cc given at 10AM and another 1cc given at 5PM. Results The rate of body weight loss was significantly decreased in the sample group. The weight of thymus was significantly increased in the sample group while the weight of spleen did not show much increase. Blood CD4+ T cell count, thymus lymphocyte count, thymus CD4+ T cell count, spleen lymphocyte count, spleen CD4+ T cell count and axillary lymph node CD4+ T cell count were significantly increased in the sample group while blood lymphocyte count and axillary lymphnode lymphocyte count did not show much increase. Conclusion As one can witness from the above results, administration of Bojungikkitang played potent role in increasing immune system among the rats treated with methotrexate which induces immunosuppression. Overall increase of lymphocyte count and CD4+ T cell count in the sample group with Bojungikkitang effectively proves its ability to boost the immune system.

EPCglobal proposed a Q-algorithm, which is used for selecting a slot-count in the next query round. However, it is impossible to allocate an optimized slot-count because the original Q-algorithm did not define an optimized weight C value. In this paper, we propose an adaptive Q-algorithm, in which we differentiate the weight values with respect to collision and empty slots. The weight values are defined with the identification time as well as the collision probability.

The purposes of this study were to evaluate the changes in hematologic indices after plateletpheresis and to identify the preapheresis platelet count and clinical factors (age, gender, height, and weight) that showed some influence on the percentage of platelet decrement, yield and efficiency. Plateletpheresis was performed on 101 healthy donors in Bundang CHA general hospital. The data was analyzed using the SAS program with t-test, ANOVA test and Multiple regression. The mean percentage decrease after plateletpheresis was 2.0% in hemoglobin, 1.8% in hematocrit, and 29.7% in the platelet count, while a WBC count showed an increase of 2.6%. The mean percentage decrease of hemoglobin and hematocrit were 1.7% and 1.4%, in males and 3.6% and 3.7% in females, respectively. Particularly the percentage decrease of platelet count was significantly higher in females (40.0%) than in males (27.2%). The platelet decrementage and yield were significantly higher in females, but the efficiency did not differ significantly between males and females. The yield showed the lowest levels in subjects who were 40 years old or over but the platelet decrement and efficiency did not change according to age. The platelet decrement increased as height and weight increased. Also, the platelet decrement and yield increased as the initial platelet counts increased, but the efficiency did not. From multiple regression analysis, the platelet decrement was associated with gender, weight, and initial platelet count. The yield was related to the initial platelet count, but the efficiency was not related to gender, age, weight, height or initial platelet counts. This study has a limitation of the generality of the study results since this study was conducted only in a single university hospital. Further study would be necessary to find out a subpopulation that is sensitive to the hematologic change after plateletpheresis, and to determine the standard criteria for blood donation based on the subpopulation.

In EPCglobal Class-1 Gen-2 RFID system, a slot-count selection algorithm has been proposed to determine the slot-count size depending on the status of reply slot. In the slot-count selection algorithm of Gen-2, the slot-count value is increased or decreased by the weight C, which is identical and independent of the slot status. It has an advantage that the algorithm is simple, but it is difficult to maintain an optimal slot-count size. Therefore, in this paper, we propose an adaptive slot-count selection algorithm, which applies the parameter C differently based on the result of tag replies. Through simulations, it is demonstrated that the collision rate for the proposed scheme is about 42% and 65% lower than the schemes proposed by Wang and Gen-2. Therefore, the adaptive slot-count selection algorithm achieves faster tag identification time compared with the existing algorithms due to the low collision rate.

Objectives This study is to find out how fungiform papillae count, which represents the density of taste buds, is related to eating behavior of children and adolescents. Methods The authors measured fungiform papillae count, height, and weight of 50 healthy children aged from 2 to 15. To evaluate the severity of anorexia, parents of the subjects answered modified version of Korean Children's Eating Behaviour Questionnaire (K-CEBQ). Children with weight of less than 50th percentile were assigned to low-weight group, while the others to high-weight group. Pearson's correlation test was conducted in order to evaluate the relationship between modified K-CEBQ score and fungiform papillae count. Results Low-weight children scored $29.8{\pm}9.1$, while high-weight children scored $24.5{\pm}7.1$. (p<0.05) on modified K-CEBQ Pearson's correlation coefficient between modified K-CEBQ score and fungiform papillae count was 0.503 (p<0.05) in low-weight group, 0.260 in high-weight group, and 0.339 (p<0.05) in total. However, there were no statistical significance in correlations between modified K-CEBQ score and percentile of weight, height, or BMI. Conclusions Severity of anorexia was correlated to the density of taste buds, especially in children who weighed less than average. The analysis on each single question indicated that children with high taste bud density had poor appetite not because of their inadequate digestive function, but because of their fastidious eating habit. Further study should be focused on finding out which specific aspect of appetite is related to the taste bud density.

The present study was carried out to produce the hematological and blood chemical findings after hypophysectomy in rats. Hypophysectomy was performed by the parapharyngeal method and the sham surgery was performed for the control group. Two weeks after the operation, the body weight of the hypophysectomized and control rats was measured daily for 5 days. We deleted the rats the weight gain of which is less than 5 g during 5 days from the hypophysectomy group. The successful operation rate was approximately 40%. In the hypophysectomized and control rats, their blood samples were collected from posterior vena cava after celiotomy under generally anesthesia with ether. Hematological parameters such as erythrocyte count, leukocyte count, hemoglobin concentration, hematocrit level, and platelet count were determined by Animal Blood Counter. The erythrocyte count, hemoglobin concentration, and hematocrit level were lower significantly (p<0.01), and the leukocyte count was lower significantly (p<0.05) in hypophysectomy group compared with control group. But the plate count did not show significant difference (p>0.05) between hypophysectomy group and control group. Also, blood chemical parameters such as glucose, blood urea nitrogen (BUN), aspartate animotransferase, albumin, total protein, cholesterol, calcium, and magnesium in serum were determined. Except BUN concentration, all parameters were not affected by hypophysectomy. But the BUN concentration was higher significantly (p<0.01) in hypophysectomy group compared with control group.

In order to investigate the mechanical properties such as tensile, bending, shearing, thickness and weight of the wool fabrics were measured by KES-F system. Samples were classified into blend ratio, weave type, fabric count. Blend ratio was classified into two groups, which are P/W blended fabric (p=63~65%, w=35~37%) and all wool fabric. Weave type was classified into four groups, which are plain, 3 harness twill, 4harness twill, satin. Cloth count was classified into three groups, which are loose, medium, tight. Statistical analysis was performed using T-test, F-test. The results were as follows; 1. There was significant difference in the thickness, tensile, bending, shearing according to the blend ratio. 2. According the weave, there was significant difference in the bending, weight and thickness in the P/W blended fabrics. There was significant difference in the tensile, weight, thickness, bending, shearing, shearing hysterisis (2HG) in the all wool fabrics. 3. There was significant difference in the shearing properties according to the fabric count.

The purpose of this study was to investigate the effect of water extract of Dioscoreae Rhizome on the reproduction activity of Wistar male rat. The group treated with 1.0 g/kg/day oral administrations of water extract of Dioscoreae Rhizoma (SK0l6) during 8 weeks was compared with the normal group. Sperm count, sperm motility, body weight, and testis weight were investigated in two groups. Sperm count. body weight, and testis weight of two groups did not show the significant difference. But sperm motility of the treated group was reduced significantly (the normal group: 56.43 %, SK0l6 group: 53.47 %, p < 0.05). According to the results, SK0l6 have no effects on sperm count, body weight. and testis weight but reduced sperm motility significantly.
