Experimental studies were done to research the effects of the Ursi fel and the UDCA on the anti-allergic effects. The results were obtained as follows: 1) In the experimental effects of the Ursi fel and the UDCA on the vascular permeability responses to intradermal Serotonin, though both of the Ursi fel and UDCA revealed the significant effect, the Ursi fel had stronger effect than the UDCA. 2) In the provocative effects of the Ursi fel and the UDCA on the vascular permeability responses to intradermal Histamin, though both of the Ursi powfel and UDCA showed the significant effect, the Ursi fel had moreerful effect than the UDCA. 3) In the 48 hours homologous passive cutaneous anaphylaxis provoked by the IgE-like antibody against white egg albumin, though both of the Ursi fel and UDCA revealed significant effect, the Ursi fel had stronger effect than the UDCA. 4) In the delayed type hypersensitivity response to Picryl Chlorede, though both of the Ursi fel and UDCA were proved to be effective significantly the Ursi fel showed stronger effect. 5) In the delayed type hypersensitivity responses to Sheep red blood cell, the Ursi fel revealed the significant effect, though the UDCA has no significant effect. According to above results, the Ursi fel was approved it could be used widely as antiallergic drug for immediate and delayed type allergic diseases. Although the UDCA revealed efficacy in immediated type allergic diseases, it had less powerful effects than the Ursi fel and it showed no effects in some experiment of delayed type allergy, so it would be difficult to be used clinically.

Objective : To evaluate the effect of Oriental medical treatment on a patient with Ramsay Hunt syndrome with poor prognosis on EMG. Methods : We applied various methods of Oriental Medical treatment including Acupuncture, Electroacupuncture, Herb medicine, Vesiculation therapy using Mylabris and Crontonis Fructus, Massage, Self-excercise of face muscles. Results : 1. Herb medicine was applied on the basis of Differentiation of Syndromes(辨證): We tried Herb medicine to improve the function of Digestive System. The patient's stool condition, subjective sensation related with abdominal pain and general condition improved. 2. We used the Vesiculation therapy using Mylabris which was used traditionally to treat Facial Palsy. We powdered Mylabris and mixed it with Crontonis Fructus to make a paste. We put it on Ye-poong(?風), Nae-gwan(內關) at left side. It induced vesicles at the applied area, but it disappeared in 48 hours without any scar. 3. We applied acupuncture, electroacupunture, massage and self-excercise of face muscles. On gross scale assessment, there was some improvement. And assessment with regional scale also showed changes. The patient and the guardian were satisfied with the result. Conclusion : We experienced a case of Ramsay Hunt syndrome with poor prognosis on EMG. She also showed poor response to conservative treatment. Through various modalities of Oriental medical treatment, we attained some clinical improvement.

In this paper we present subject region-based auto-focusing algorithm using noise robust focus measure. The proposed algorithm automatically estimates the main subject using entropy and solves the traditional problems with a subject position or high frequency component of background image. We also propose a new focus measure by analyzing the discrete cosine transform coefficients. Experimental results show that the proposed method is more robust to Gaussian and impulse noises than the traditional methods. The proposed algorithm can be applied to Pan-tilt-zoom (PTZ) cameras in the intelligent video surveillance system.

This paper proposes a composite filter for noise reduction of image. To improve the image quality by reducing the noise in the liver ultrasound image, we tried to help the accurate image analysis. In the experiment, the top seven composite filters were selected by combining the Gaussian blur filter, the sharpening filter, and the median filter using the ATS-539 ultrasonic phantom, and applied to the ultrasound image in which this was done. As a result, it was found that the values of SNR, CNR and MSR all increased when the top seven composite filters were applied. In addition, PSNR of more than 30 dB, close to SSIM 1 showed that the image loss rate is small. Therefore, the appropriate application of the proposed composite filter in this research will be useful for accurate video reading and analysis.

Acute gastric volvulus is uncommon but surgically emergent. Normally, the stomach is held in position by four ligaments: gastrophrenic, gastrohepatic, gastrosplenic, and gastrocolic. In addition, relative fixation of the pylorus and esophagus provides further anchorage. A normal diaphragm also helps to prevent abnormal displacement of abdominal viscera and development of gastric volvulus. Volvulus may be organoaxial, mesenteroaxial, or a combination of both. Organoaxial volvulus is the rotation of the stomach around an axis extending from the hiatus of the diaphragm to the pylorus. Mesenteroaxial volvulus is the rotation of the stomach around an axis transecting the lesser and greater curvatures of the stomach. The symptoms of gastric volvulus depend on its type, the extent and degree of rotation and obstruction, and associated defects. Classic clinical features of acute gastric volvulus, as by Borchardt in 1904, include unproductive retching, acute, localized epigastric distention, and the inability to pass a NG tube. The presence and severity of these features depend on the degree of gastric obstruction of both the gastroesophageal junction and pyloric outlet. It may be suspected on plain abdominal radiographs and usually confirmed by upper gastrointestinal series. Acute volvulus requires immediate surgical repair, fixation to avoid recurrence, and correction of any underlying anatomic abnormality. Any associate defect should be repaired and the stomach must be fixed. The authors report a case of an 3-year-old girl who had a mesenterioaxial gastric volvulus.

In dance sport, hip movement is the most basic and essential technique, connecting the body movements to make the body move organically, and providing an overall balance of body movements. From that perspective, this study focused on the Cucarachas movement, representing a series of efficient hip movements in the center of gravity. For the purposes of this study, 4 dance sport participants who had won prizes at international contests were selected in order to analyze such variables as the radius of gyration (shift) on the hips and the shift of the center of gravity when scapula depression was performed and when it was not. To examine differences in these kinematic variables, a paired t-test was conducted, resulting in the following findings: First, the dancers were found to be able to control scapula depression, and a significant difference was observed in the vertical axis(Z) between the times when scapula depression was performed and when it was not. Second, when scapula depression was performed, shifts in the left-right axis(X) and anterior-posterior axis(Y) were found; the left-right axis showed a greater difference than the anterior-posterior axis. Third, scapula depression was found to have an influence on the shift to the left-right axis(X) of the center of gravity.

In this paper, we propose to identify redundant power states of high-level power model based on clock gating enable signals(CGENs) using dependencies of Boolean functions and structural dependencies of clock gating cells. Three functional dependencies between two CGENs, namely equvalence, inversion, and inclusion, are used. Functions of CGENs in a circuit are represented by binary decision diagrams (BDDs) and the functional relations are used to reduce the number of power states. The structural dependency appears when a clock gating cell drives another clock gating cells in a circuit. Automatic dependency checking algorithm has been proposed. The experimental results show the average number of power state is reduced by 59%.

The Pierre Robin sequence (PRS) is the nonrandom association of micrognathia, cleft palate, and glossoptosis, leading to respiratory and feeding difficulties that appear neurogenic rather than mechanical in causation. Genetic determinants are thought to underlie this functional and morphological entity, based on the existence of Mendelian syndromes with PRS. Here, we demonstrate the association of PRS with trisomy 8p due to duplication of a segment as the karyotype 46,XX,dup(8)(p21.3p23.1) and confirm the additional materials as chromosome 8 via whole chromosome paint probes. Our observation supports the hypothesis regarding a genetic basis for nonsyndromic PRS, strengthens the possible genetic association with isolated cleft palate, and provides a candidate PRS locus in chromosomal region 8(p21.3p23.1).

Objectives : The present study was designed to investigate effects of mixed extract from korean medicinal herbs (MIX) on oxidation/reduction reaction-related and aging-related enzyme in vitro. Methods : We performed MTT assay, collagenase inhibition assay, elastase inhibition assay, tyrosinase inhibition assay, DPPH free radical scavenging assay, SOD-like activity and xanthine oxidase inhibition assay. Results : Recently, many studies have reported that elastin is also involved in inhibiting or repairing wrinkle formation, although collagen is a major factor in the skin wrinkle formation. The MIX showed 97% inhibition of collagenase activity, and 64% inhibition of elastase activity at 1 mg/ml concentration of MIX, next only to positive control, which indicate good efficacy for anti-wrinkle ingredient. Also it's treatment showed 34% inhibition of tyrosinase activity, to relate whitening effect, at the same dose of MIX. Antioxidant activities were determined by DPPH radical scavenging, xanthine oxidase (XO) inhibiting activity and SOD-like activity. Also these scavenging, XO-inhibiting and SOD-like activities were measured in 91%, 80%, and 63% inhibition, respectively, at a treated dose of 1 mg/ml, compare to control. Conclusions : These results suggest that possibility of mixed korean medicinal herbs as a functional ingredient for anti-wrinkle and whitening, anti-oxidation and anti-aging cosmetic formula.

Shipping Along with the aging of the total population, its importance is greater cause of stroke, which is one of the diseases are listed cerebral perfusion is about 80%,.ie that the flow of blood flowing to the brain is reduced as the cause. One of the most typical prophylaxis and treatment of these stroke is to enhance cerebral perfusion. There are several ways to increase cerebral blood flow are a therapy through drugs, through surgery and invasive NeuroFlo. NeuroFlo is to insert a catheter to which a balloon is attached into a patient's artery. However, since the method of enhancing conventional cerebral perfusion have been conducted mainly in invasive method, giving a burden to the patient, the problem of inducing a number of complications were noted. In this paper, an attempt to supplement the shortcomings of such invasive brain perfusion increase method, to provide a device to enhance the non-invasively brain perfusion.
