Background: The purpose of this study was to compare the differences in gait and mobility according to the types of assistive device for ankle joint including ankle foot orthosis (AFO), non-elastic tape, elastic tape, and high ankle shoes in chronic hemiplegic stroke survivors. Design: A cross-over design. Methods: Twelve hemiplegic stroke survivors participated in this study, and they walked under 5 different conditions including bare feet, wearing a AFO, wearing a non-elastic tape, wearing a elastic tape, and wearing a high ankle shoes. During the participants walked, the spatio-temporal gait analysis and mobility examinations were performed. For the spatio-temporal gait analysis (gait velocity and cadence, step length, stride length, and single and double leg support time) and mobility examinations, the gait mat, TUG and TUDS were used. Results: As s results, on the AFO, non-elastic tape, elastic tape, and high ankle shoes, there were significantly differences in the all spatio-temporal gait parameters, TUG, and TUDS compared to barefoot (p<0.05). In particular, all spatio-temporal gait parameters, TUG, TUDS were significantly improved with AFO compared to barefoot. TUG was significantly improved with AFO compared to non-elastic tape, TUG and TUDS were significantly improved with AFO compared to elastic tape, gait velocity was significantly improved with non-elastic tape compared to high ankle shoes, gait velocity and TUG were significantly improved with elastic tape compared to high ankle shoes, and TUDS was significantly improved with non-elastic tape compared to elastic tape. Conclusion: The AFO, non-elastic tape, elastic tape, and high ankle shoes showed a positive effect on gait and mobility compared to barefoot, and among them, wearing AFO was most effective for improving gait and mobility of chronic hemiplegic stroke survivors.

본 논문에서는 현재 표준화가 진행중인 HEVC 의 고정 비트율(CBR) 부호화를 위한 비트율 제어(rate control) 기법을 다룬다. HEVC 의 임의접근(Random Access: RA) 부호화 모드는 계층적-B 부호화 구조를 통해 높은 부호화 효율을 제공할 수 있다. 기존의 HEVC 를 위한 비트율 제어 방식으로는 2 차 비트율-왜곡 모델 기반의 시간계층 및 프레임 타입에 따른 비트율 특성을 반영한 프레임 레벨의 비트율 제어 기법이 제시되었다. 이 같은 기존의 프레임 레벨의 비트율 제어 기법은 임의접근 모드의 계층적-B 구조에서 동작 성능이 확인되었으나, HEVC 의 기본적인 부호화 단위(Coding Unit: CU)의 특성이 반영되지 않아 비트율 제어의 정확성이 제한되었다. 본 논문에서는 기존의 계층적 부호화 구조를 고려한 프레임 레벨의 비트율 제어 기법을 확장한 CU 레벨에서의 비트율 제어 기법을 제시하고 모의실험을 통해 제시된 기법의 비트율 제어 성능을 확인한다.

N/A Objectives: Recirculation is one of the factors preventing effective hemodialysis(HD) and one of the methods which can detect vascular access stenosis. We analyzed the possible clinical risk factors and relationship between the recirculation rate(R) and adequacy of hemodialysis. Also, we attempted to find out whether vascular access stenosis actually exist in the high R group. Methods: We examined the period of hemodialysis, the presence of diabetes mellitus(DM), use of artificial grafts, the venous pressure(VP) during HD, the difference(ΔKt/V) between prescribed Kt/V(Kt/V') and delivered Kt/V(Kt/V) in 113 patients(22 DM, 39 artifical graft patients) receving maintenence HD. R was obtained by two needle slow flow method. Fistulogram was performed in the high R group(R>10%) and if significant stenosis was found, surgical correction was performed followed by repeated R, VP, Kt/V measurement. Results: As a whole R was 5.6%(±8.8), VP was 92mmHg(±44), the duration of hemodialysis was 36 months(±25) and Kt/V was 1.20 (±0.29). The VP of the group with artificial graft was higher than that of the group with native fistula, but there was no relationship between R and duration of HD, Kt/V, ΔKt/V as a whole. The VP and ΔKt/V of group with high R(>10%) were significantly higher than the group with low R(<10%). Positive correlation between R and ΔKt/V was demonstrated in the group with high R. In six patients with high R, fistulograms were taken and significant vascular stenosis were found. After surgical correction, R was significantly decreased from 25.5% to 5.2%. On the other hand, the R as well as the rate of diabetes or prosthetic grafts were higher in the group with high VP(≥100mmHg) than in the group with low VP(<100mmHg) as well as in patients with diabetes or prosthetic grafts, Conclusion: We believe recirculation should be measured during maintenance HD especially when the patient has diabetes, artificial graft or high venous pressure during HD. When the recirculation rate is high, reconstructive vascular surgery with proprer mediacl management may lead to better dialysis adequacy.

N/A Background : Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease of unknown etiology. The disease is relatively common in western countries, but so far, only about 20 cases have been reported in Korea. Thus, the purpose of our prospective study was to evaluate the clinical characteristics of PBC in Korea. Methods : Between October 1994 and February 1999, 16 patients diagnosed as PBC at our department were enrolled in this study. We analyzed these patients for the distribution of age and sex, initial symptoms and signs, associated disorders, laboratory, endoscopic, and radiologic and histologic findings. Results : Of the 16 patients, the ratio of male to female was 1:7 and the average age was 57.5 years. Pruritus (37.5%) was the most frequent presenting symptom followed by xerostomia and xerophthalmia (12.5%), jaundice (6.3%), chronic fatigue (6.3%), melena (6.3%). Associated disorders were Sj gren's syndrome (25%), arthropathy (12.5%), Raynaud's phenomenon (6.3%) and diabetes (6.3%). Abnormalities of liver function were found frequently. Antimitochondrial antibody (100%), antinuclear antibody (31.25%) and rheumatoid factor (31.25%) were found. Long-term administration of UDCA improved both clinical and biochemical signs in most patients, however, 2 patients experienced exacerbation during UDCA therapy. Conclusions : We experienced 16 cases of PBC within a short period. It is expected that we can find these patients more frequently if we suspect this disease in patients with pruritus and unexplained obstructive pattern of liver function abnormality.(Korean. J. Med 59:634-640, 2000)

Objectives : This experiment was performed in order to study the effect of Maekmundong-tang on dyspnea patients. Methods : This study involved 14 dyspnea patients from March 1, 2012 to May 31, 2012. Lung capacity of the patients is evaluated with Peak flow meter. Results : Maekmundong-tang administration was revealed effect on dyspnea patients' lung capacity. Conclusions : It was found that Maekmundong-tang administration was effective on dyspnea patients' lung capacity. The mean degree of improvement was 21.79(L/min). It was shown that the more mild dyspnea level was, the more effective and short-term administration more effective.
