If there was spleen vacuity presenting with a sallow yellow 100 mg dipyridamole with mastercard hypertension 2014 guidelines, lusterless facial complex- ion purchase dipyridamole 25mg with visa blood pressure normal heart rate high, feeble spirit, emaciation, shortness of breath, laziness to speak, torpid intake, sloppy stools, a tender, pale tongue with white fur, and a fine, vacuous pulse, 5-10 grams of stir-fried Bai Zhu (Rhizoma Atractylodis Macrocephalae) and Fu Ling (Poria) were added. The continuous administration of 10 packets of these medicinals equaled one course of treatment. Hou, the cerebrum, urination, and spinal function on the whole have already been established in children more than three years old, and their kidney function also has already basical- ly reached normal adult standards. Therefore, the child is already able control their desire to urinate and urinate at will. Thus, the child does not always have command of their urination during sleep. According to Chinese medicine, the regulation of water fluids in the human body is controlled by the spleen, lungs, kidneys, and triple burner. In that case, one cannot contain oneself, thus causing enuresis and urinary incontinence. Based on the preceding theory, within the above formula, Shan Yao fortifies the spleen and supplements the lungs and kidneys. Yi Zhi Ren warms and supplements the spleen and kidneys and astringes urination. Therefore, the formula as a whole has the function of supplementing the kidneys, scattering cold and reducing urine. In terms of spleen vacuity loss of restraint, stir- fried Bai Zhu and Fu Ling increase the functions of strengthening and supplementing the qi as well as fortifying the spleen to pro- mote the astringing of urine. Generally, doctors do not use greatly hot or drastical- ly supplementing medicinals. In this case, Tu Si Zi, Yi Zhi Ren, and Bu Gu Zhi are three medicinals that are added to strengthen and supplement kidney yang and boost kidney yin. In a small number of cases of severe kidney yang vacuity debilitation, Dr. Hou rec- ommends the practitioner to use their discretion and also add Rou Gui and Zhi Fu Zi. From Clinical Observations on 220 Cases of Enuresis by Huang Xiang-juan, Shang Hai Zhong Yi Yao Za Zhi (Shanghai Journal of Chinese Medicine & Medicinals), 1991, #11, p. There were 190 cases between 1-9 years old, seven cases between 10-19 years old, and 23 cases were more than 20 years old. The course of disease was less than one year in 18 cases, 1-2 years in 76 cases, 3-4 years in 92 cases, and more than five years in 34 cases. The frequency of enuresis ranged from one time per several days in 42 cases, to one time per night in 38 cases, to two or more times per week in 140 cases. One hundred sixteen cases presented a kidney yang vacuity pattern which consisted of a lusterless facial complexion, fatigued essence-spirit, cold limbs, a pale tongue with thin fur, and a fine pulse. Another 55 cases presented a kidney yin vacuity pattern which consisted of a dry mouth, sore throat, dizziness, tinnitus, lumber soreness, fatigue, an emaciated body, a red tongue with thin fur, and a fine, slightly rapid pulse. Yet another 49 cases pre- sented a pattern of qi and blood vacuity which consisted of a bright facial complexion, shortage of qi, laziness to speak, a pale tongue with thin fur, and a fine pulse. Treatment method: Those with kidney yang vacuity were administered a formula com- posed of: Shu Di (cooked Radix Rehmanniae), 12g Shan Yao (Radix Dioscoreae), 12g Du Zhong (Cortex Eucommiae), 12g Xu Duan (Radix Dipsaci), 12g 70 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine Tu Si Zi (Semen Cuscutae), 12g Jin Ying Zi (Fructus Rosae Laevigatae), 12g Shan Zhu Yu (Fructus Corni), 12g Fu Ling (Poria), 12g Ze Xie (Rhizoma Alismatis), 12g Qian Shi (Semen Euryalis), 12g Suo Quan Wan (Reduce the Stream Pills), 12g If there was severe lumbar soreness, 12 grams of Gou Ji (Rhizoma Cibotii) were added. If there were teeth-marks on the side of the tongue, 12 grams each of mix-fried Huang Qi (Radix Astragali) and stir-fried Dang Shen (Radix Codonopsitis) were added. If there were severe cold limbs, three grams each of Gan Jiang (dry Rhizoma Zingiberis) and Zhi Fu Zi (Radix Lateralis Praeparatus Aconiti Carmichaeli) were added. If there was long, clear, copious urination, 12 grams of Fu Pen Zi (Fructus Rubi) were added. Those with kidney yin vacuity were administered: Sheng Di (uncooked Radix Rehmanniae), 9g Bai Shao (Radix Paeoniae Albae), 9g Zhi Mu (Rhizoma Anemarrhenae), 9g Huang Bai (Cortex Phellodendri), 9g Lian Xu (Stamen Nelumbinis), 9g Shan Zhu Yu (Fructus Corni), 12g calcined Long Gu (Os Draconis), 12g Mu Li (Concha Ostreae), 12g Sang Ji Sheng (Herba Taxilli), 18g Wu Wei Zi (Fructus Schisandrae), 3g mix-fried Gan Cao (Radix Glycyrrhizae), 3g If there was severe lumbar soreness, 12 grams of Du Zhong (Cortex Eucommiae) and nine grams of Niu Xi (Radix Achyranthis Bidentatae) were added. Those presenting a qi and blood vacuity pattern were given: mix-fried Huang Qi (Radix Astragali), 12g Dang Shen (Radix Codonopsitis), 12g Bai Zhu (Rhizoma Atractylodis Macrocephalae), 12g Dang Gui (Radix Angelicae Sinensis), 12g Huang Jing (Rhizoma Polygonati), 12g Chinese Research on the Treatment of Pediatric Enuresis 71 Bai Shao (Radix Paeoniae Albae), 12g calcined Long Gu (Os Draconis), 12g calcined Mu Li (Concha Ostreae), 12g Wu Wei Zi (Fructus Schisandrae), 3g mix-fried Sheng Ma (Rhizoma Cimicifugae), 3g mix-fried Gan Cao (Radix Glycyrrhizae), 3g Chai Hu (Radix Bupleuri), 6-9g Can Jian Ke (Coccum Bombycis), 6-9g For frequent urination, 12 grams each of Suo Quan Wan (Reduce the Stream Pills) and Qian Shi (Semen Euryalis) were added.
The MDBMS can scan all such data to build a proﬁle of how the di¤erent ﬁngers move relative to each other buy 100 mg dipyridamole with amex pulse pressure less than 30. If two limbs always move with one another purchase dipyridamole 25mg without prescription blood pressure joint pain, then it might be feasible to hypothesize that these two limbs are dependent on one another. The objective here is to create a framework that can detect interesting spatio-temporal patterns based on the underlying data. These patterns can serve as a framework when activating the glove to move a single ﬁnger. Real-Time Spatiotemporal Databases 169 Query Processing The database management system should be able to accept spatiotemporal input from the user to retrieve all those spatiotemporal datasets that match the input data. One example would be for a patient to request retrieval of all those activities that involve the folding of the index ﬁnger. Another example is an automated system that translates the hand signs performed by a hearing-impaired individual into text to facilitate communication (Murakami and Taguchi, 1991; Fels and Hinton, 1995; Sandberg, 1997; Nam and Wohn, 1996; Lee and Yangsheng, 1996; Wu and Huang, 1999). Next, these characters are printed on a screen, conveying what the individual is trying to say. We have investigated a role for clustering techniques in supporting retrieval of spatial data. Our objectives were to detect a hand sign from a continuous stream of haptic data generated by a glove. We used an implementation of K-Means (MacQueen, 1967; Jain and Dubes, 1988; Ng and Yang, 1994) and Adaptive (Martin-Bautista and Vila, 1999; Carrasco et al. Our study assumed a sim- pliﬁed environment consisting of two steps: training and data lookup. During train- ing, a user issues a ﬁxed number of hand signs and repeats them several times. The system detects the di¤erent clusters that represent each class with no prior knowledge of classes. During lookup, the user repeats a hand sign, and the system compares it with the available clusters to identify the best match. The K-Means algorithm requires the user to specify the number of classes K, where each class corresponds to a sign. It forms the cluster by minimizing the sum of squared distances from all patterns in a cluster to the center of the cluster. The pattern samples are constructed using the twenty-two sensors that pertain to the po- sition of di¤erent joints that constitute a hand. It is more general than K-Means because it does not require a pri- ori knowledge of K. It assigns an input training record to a cluster when the distance from the sample to the cluster is below y Â t where y is the distance threshold and t is a fraction between 0 and 1. Adaptive does not create a new cluster when this distance is greater than t. Moreover, it does not make a decision when the sample record falls in an intermediate region. Once the 170 Shahram Ghandeharizadeh training ends, it assigns all patterns to the nearest class according to the minimum distance rule, that is, Euclidean distance. It may leave some patterns unclassiﬁed if their distances to all cluster centers are greater than t. The results obtained demonstrate that both clustering algorithms are de- pendent on the input training dataset, its size, and the order in which the data are presented to the algorithm. Generally speaking, K-Means is the more sensitive, pro- viding an accuracy that ranges between 55 and 83% (depending on the input data and the order in which they are presented to the algorithm). Adaptive is less sensi- tive, with its accuracy ranging between 66 and 77%. This is because Adaptive delays the formation of clusters and does not assign a training set to one of them.
