  • In video coding systems, an effective rate control method is one of the most improtant issues for the good video quality. This paper presents an adaptive rate control scheme based on the buffer fullness, quantization, and buffer utilization for very low bit rate communication lines, such as 16kbit/s, 24bit/s, and so on. The strategy is implemented on H.263, whichis a vide coding algorithm for narrow band telecommunication channels up to 64kbit/s recommended by ITU-T SG15, to show the effectiveness. The simulation result shows that the suggested rate control scheme has better SNR performance and buffer utilization of source coder than those of linear and non-linear[9] buffer control strategies.

  • We present a simple and cost effective rate control scheme for streaming video over a wireless channel by using the information of mobile devices' buffer level. To prevent buffer fullness and emptiness at receivers, the server should be able to adjust sending rate according to receivers' buffer status. We propose methods to adjust sending rate based on the buffer level and discrete derivative of the buffer occupancy. To be compatible with existing network protocols, we provide methods to adjust sending rate by changing the inter-packet delay (IPD) at the server side. At every round-trip time, adjustments of sending rate are made in order to achieve responsiveness to sudden changes of buffer availabilities. A series of simulations and the prototype system showed that the proposed methods did not cause buffer overflows and it can maintain smoother rate control and react to bandwidth changes promptly.

  • Accumulation of pathogens in chest refers to a syndrome of fullness, stuffiness and pain in the chest, diaphragm, epigastrium and abdomen, which is ascribable to accumulation of pathogenic heat with stagnancy of fluid or phlegm in the chest. Retching refers to vomiting with sound but without any vomitus. It is usually ascribable to adverse flow of ki due to deficiency of stomach, or by pathogenic heat or cold, and failure in descending of the stomach-ki. It may also be found in Soyang disease. Bloody purulent stool refers to passing stool with blood and pus. It is formed mainly due to invasion of the stomach and the intestines by epidemic pathogenic summer-heat, steaming of stagnateed damp-heat fighting against ki and blood, or improper diet, obstruction of bu-ki stagnation of blood and ki.

  • Even in the absence of any specific abnormal pathologic findings of the gastrointestinal tract, many patients still suffer from : fullness, anorexia and postprandial abdominal pain. As these symptoms are similar to visceral origin pain, many physicians focus on the discovery of pathologic abnormality of the gastrointestinal tract. At our Yoido Pain Clinic, after diagnosing myofascial pain syndrome, we treated 64 patients by trigger point injection and physical therapy on abnormal abdominal muscle, from June 1993 to April 1995. Most patients' conditions improved after these treatments.

  • The dynamic characteristics during gear ratio change including the disturbance of output torque has been one of the most important issues in the study of automatic transmissions of passenger cars. In this paper, to investigate the dynamic characteristics of a passenger car automatic transmission during gear ratio change, a dynamic model of the driveline of a passenger car focused on the automatic transmission is proposed and the dynamic simulation program is developed. The results of the simulation show good agreements with the experimental data, which process the use fullness of the dynamic model and the simulation of the driveline.

  • Objectives : The prevalence of peptic ulcer disease is estimated about 10% in Korea, and has declined due to Helicobacter pylori eradication therapy. Symptoms of peptic ulcer are postprandial epigastric pain, hunger pain, anorexia, nauea, vomiting, soreness, postprandial fullness, postparandial discomfort. The purpose of the study was to evaluate the effectiveness of the Anjungsan in the improvement of the symptoms in patients with peptic ulcer. Methods : After taking Anjungsan to patient with peptic ulcer, Examined to assess the improvemnet by Ordinal Scale VI grade and VAS. Results : Patients with symptoms of the appeal was taking Anjungsan gets better after 3 dyas appeared to be more than half. And 11 days after treatment all symptoms were improved under the VAS 1-2 except for epigastric lump sensation. Conclusions : After treatment with Anjungsan, patient showed improvement in all symptoms associated with peptic ulcer.

  • A 40-year-old man was admitted with chief complaints of sudden hearing loss, ear fullness and tinnitus of 12 days duration developed following SCUBA diving. An exploratory tympanotomy was done on 16th day of onset, and a small leakage of clear fluid was found on the anterior portion of the stapediovestibular joint, which was sealed off by small piece of fatty tissue from the ear lobe. Postoperatively, his PTA's was improved from 85㏈ to 15㏈, however high tone was remained unchanged above 4KHz. More exploration of the middle ear will be helpful to find the labyrinthine fistula causing sudden type of hearing loss.

  • Objectives The purpose of this study is to report the effect of oriental demonstration treatment for episodic vertigo of Meniere's disease. Meniere's Disease characterized by recurrent prostrating episodic vertigo, nausea, vomiting, sensory hearing loss, tinnitus, and a feeling of fullness in the ear associated with generalized dilation of the membranous labyrinth (endolymphatic hydrops). The cause of Meniere's disease is unknown, and the pathophysiology is poorly understood. Methods We experienced one case of Meniere's disease treated with Asian medical treatment, acupuncture and herbal medication. 64-year-old female patient was diagnosed with Meniere's disease by western medical doctor. Methods: Saam acupuncture Sojangjungkyuk applied to the patient. Results After treatment her episodic vertigo, nausea, vomiting and endolymphatic hydrops were decreased but the level of tinnitus it was not improved as much as other symptoms. Conclusions Saam Acupuncture of Asian medical treatment could be safe and effective.

  • Meniere's disease is not a life-threatening but lift-altering inner ear disease characterized by episodic vertigo, fluctuating hearing loss, tinnitus and ear fullness. The etiology and pathophysiology symptoms is still disputed. Thereby the treatment of Meniere's disease is empirical. As yet no treatment has prospectively modified the clinical course of condition and thereby prevented the progressive hearing loss. We experienced two cases of Meniere's disease treated with oriental medical treatment, acupuncture and herbal medication. 15 year-old and 23 year old male patients had diagnosed Meniere's disease by western medical doctor. After treatment their vertigo is decreased and the level of hearing loss was rise up. Therefore, oriental medical treatments could be safe and effective methods.

  • Barium suspension, oral iodine contrast medium and water were applied in eight dogs to evaluate (1) distension of gastrointestinal tract, (2) the effect of the oral contrast media on the identification of the pancreas from surrounding organs, and (3) image quality and the presence of artifacts in canine pancreas computed tomography (CT) images. Oral iodine contrast medium, gastrografin, produced significant artifacts that deteriorated the CT images of the pancreas. The use of water did not provide the fullness of the gastrointestinal lumens. Barium suspension was effective for the identification of the pancreas from the surrounding gastrointestinal tract, without significantly increasing image noise. Barium suspension can be used as an optimal contrast medium that will not cause an adverse effect on the pancreatic density and image quality.
