In this paper, we present a performance analysis for an MPEG-4 video codec based on the on-chip network communication architecture. The existing on-chip buses of system-on-a-chip (SoC) have some limitation on data traffic bandwidth since a large number of silicon IPs share the bus. An on-chip network is introduced to solve the problem of on-chip buses, in which the concept of a computer network is applied to the communication architecture of SoC. We compared the performance of the MPEG-4 video codec based on the on-chip network and Advanced Micro-controller Bus Architecture (AMBA) on-chip bus. Experimental results show that the performance of the MPEG-4 video codec based on the on-chip network is improved over 50% compared to the design based on a multi-layer AMBA bus.

Objective : The purpose of this study was to know the clinical effects of hydrotherapy based Ultrasonic spa using SoPung-Tang on pulse wave velocity in patients with sequelae of CVA. Methods : PWV(Pulse wave velocity), Bio Chemistry, Hematology, Blood Pressure were investigated in 20 patients(Experimental group 13, Control group 7) who have been in Semyung Oriental medicine hospital from December 2005 to February 2006. Results : 1. In experimental group, Rt PWV diminished 4.8%, Lt PWV 5.1%. 2. In control group, Rt PWV diminished 3.3%, Lt PWV 1.8%. Conclusion : Hydrotherapy based Ultrasonic spa using SoPung-Tang showed useful effects in patients with sequelae of CVA.

Magnesium alloys have many advantages such as light-weight, high machinability, damping capacity, etc. So magnesium alloy parts have been used in transportation, mobile phone, military industries. Because of HCP atomic structure, Magnesium is very difficult in plastic deformation process, so most of magnesium products are fabricated by casting process. Magnesium alloys have low heat-capacity, high fluidity and low Fe solubility. For these reasons it is more suitable than aluminum in mass-production by casting. And various casting technologies have been developed. So casting technologies for magnesium developed recently is discussed in this paper.

A 49-year-old man with drowsy mentality was diagnosed with acute type A aortic dissection; he underwent an emergency operation. When selective antegrade cerebral perfusion was initiated, the right regional cerebral oxygen saturation ($rSO_2$) decreased as compared to the left one. Adequate blood flow was perfused through the branch of the artificial graft, after distal anastomosis, but the right $rSO_2$ did not recover. Angiography revealed another intimal tear on the right common carotid artery. A stent was then inserted. The right $rSO_2$ promptly increased to the same level as that of the left one. The patient was discharged without any neurologic complications.

Objectives: This study was designed to investigate characteristics of digital infrared thermal imaging (DITI) and quantitative evaluations in patients with burning mouth syndrome (BMS). Methods: We reviewed the clinical records of 38 patients with BMS who visited the Oral Diseases Clinic of Kyung Hee University Korean Medicine Hospital from March 1st, 2018 to June 30th, 2018. The subjects were evaluated with digital infrared thermal imaging (DITI) and for heart rate variability (HRV), unstimulated salivary flow rate (USFR), and the proportion of coated tongue. Results: Most patients showed higher temperatures on the central part of the tongue (T2) than on the middle of the forehead (T1). The patients tended to have a high Low frequency/High frequency (LF/HF) ratio. Statistically significant negative correlations were noted between the age of patients and the temperature of T1 and T2. Statistically significant negative correlations were also observed between the LF/HF ratio and 'T1-T2' values. Conclusions: This study suggests that DITI and HRV are useful for the validation of patients with BMS. Correlations between the result values suggest that sympathetic function acceleration is related to temperature distribution and, ultimately, to symptoms.

Objective: The aim of this study was to investigate the clinical characteristics of patients showing fissured tongue (FT) with burning mouth syndrome (BMS). Methods: We reviewed the clinical records of 16 FT patients with BMS who visited the Oral Diseases Clinic of Kyung Hee University Korean Medicine Hospital from March 1, 2017 to February 28, 2018. The subjects were graded by FT classification and compared with each group on a numeral rating scale (NRS) of tongue pain, proportion of coated tongue, unstimulated salivary flow rate (USFR), Ryodoraku, and heart rate variability (HRV) results. Results: FT grade had no significant correlation with NRS of tongue pain and USFR. FT grade had a substantially significant positive correlation with BMI and LF/HF ratio in HRV. FT grade had a substantially significant negative correlation with proportion of coated tongue. The most frequent accompanying symptoms were xerostomia and insomnia. Conclusions: The results of this study suggest that FT has no correlation with tongue pain in BMS. Rather, FT seems to correlate with sympathetic function acceleration.

Background : Vascular dementia occurs mainly due to cerebral vascular disease. So we performed this clinical study to investigate the incidence and characteristics of vascular dementia in stroke patients. Methods : This study was performed on the patients hospitalized from April 1, 1998 to August 31, 1998 at the department of circulatory internal medicine, hospital of Oriental medicine, Kyung-Hee University, and diagnosed cerebral infarction or hemorrhage by Brain CT or MRI. we devided the patients into two groups; vascular dementia group and non dementia group according to MMSE-K(Mini Mental State Examination Korean version), Hasegawa dementia scale. Patients were diagnosed dementia using DSM-IV. We compared general characteristics, stoke types and laboratory findings between the two groups and investigated the correlationship between MMSE-K and Hasegawa dementia scale. Results : Results showed that the incidence of vascular dementia was about 27.8% in stroke patients. The greater number of subjects with dementia were women in the lower educational classes and had lower MBI(Moderfied Bathel Index) scores. Vascular dementia were more common in patients with large brain lesion size($>20cm^3$). There was a positive correlationship between Hasegawa scores and MMSE-K.

1. Objectives The Face is an important standard for the classification of Sasang Contitutions. Now We are developing 3D Face Automatic Recognition Apparatus to analyse the facial characteristics. This apparatus show us 3D image of man's face and measure facial figure. We should examine accuracy of position recognition in 3D Face Automatic Recognition Apparatus. 2. Methods We took a photograph of Face status with Land Mark 8 times using Face Automatic Recognition Apparatus. Each taking-photo, We span Face statusby 10 degree. At last time, We took a photograph of Face status's lateral face. And We analysed Error Averige of Distance between seven Land Marks. So We examined the accuracy of position recognition in 3D Face Automatic Recognition Apparatus at indirectly in degree changing of Face status. 3. Results and Conclusions According to degree change of Face status, Error Averige of Distance between Seven Land Marks is 0.1848mm. In conclusion, We assessed that accuracy of position recognition in 3D Face Automatic Recognition Apparatus is considerably good in spite of degree changing of Face status

Objective: This case study reports on the result of Korean medicine treatment of diffuse esophageal spasm. Methods: A 46-year-old female Korean patient with diffuse esophageal spasm received electroacupuncture, herbal medicine, and moxibustion treatment for 2 weeks in hospital. Results: Decreases in the visual analog scale (VAS) (from 8.7 to 7.0), numeric rating scale (NRS) (from 7.0 to 5.5), gastrointestinal symptom rating scale (GSRS) (from 9 to 6), and gastroesophageal reflux disease-health related quality of life questionnaire (GERD-HRQL) (from 46 to 38) scores were observed after the treatment. Conclusion: Evaluation of Korean medicine treatment is worthwhile for rare diseases like diffuse esophageal spasm.
