  • Purpose: The purpose of this study is to assess the effectiveness of short-wave therapy (SWT) for treatment of knee osteoarthritis (OA) as compared to placebo and control, and to assess the question of whether the effects are related to the mode, dosage, and application method. Methods: We searched randomized, placebo-controlled trials using electronic databases. We also manually reviewed sources in order to identify additional relevant studies. Results: Eight studies (597 participants) with OA were included in the meta-analysis. Pulse SWT had a significant effect on pain relief compared with control treatment, while did not favour compared with the placebo group. Pulse SWT had a significant effect on functional improvement compared with control and placebo treatment. Continuous SWT had no effect on pain relief and functional improvement. Capacitive SWT a significant effect on pain relief, functional improvement, and muscle strength. Continuous and capacitive SWT had increased muscle strength significantly. We found no clinical significance of all outcomes except pain and functional improvement in pulsed SWT with low dose. There was no difference in adverse events. None of the participants experienced any serious adverse events. Conclusion: Low dose pulsed SWT provided a short-term clinical benefit for pain relief and functional improvement. Pulsed SWD with low and high dose had effects on pain and function. There seems to be a placebo effect. We found significant effects on pain and function in capacitive SWT. Despite some positive findings, this analysis lacked data on how effectiveness is affected by mode, dosage, and application method of SWT. Further well-designed clinical studies are required in order to confirm the effectiveness of SWT.

  • Java 플랫폼 기반 스크립트 언어인 Groovy는 Java와 같은 객체지향 언어지만 Java보다 훨씬 고급 수준의 언어로서 간결한 코드와 쉬운 프로그래밍 환경을 제공한다. Groovy가 제공하고 있는 기능 중에서 GroovyMarkup은 XML 문서와 같이 각각의 객체가 중첩된 트리 구조를 다루는 응용프로그램을 쉽게 생성할 수 있도륵 해준다. GUI 프로그램은 Component 및 Container 객체가 중첩된 구조로 이루어져 있으므로 GroovyMarkup을 이용하면 GUI 프로그램을 간결하고 쉽게 작성할 수 있다. 본 논문에서는 Java 플랫폼 GUI 중 최근 각광 받고 있는 SWT(Standard Widget Toolkit)를 Groovy에서 지원할 수 있게 GroovyMarkup을 확장하여 SWT Builder를 설계한다. SWT Builder는 마크업 형태로 기술한 SWT widget 이름과 속성을 SWT widget 객체와 일대일로 대응하는 구조로 설계된다. 따라서 GUI 프로그램의 골격을 구성하는 SWT Builder를 마크업 형식의 코드로 작성하고 GUI 컴포넌트 내의 이벤트 처리는 클로저(closure)를 이용함으로써 좋은 성능을 내는 GUI 프로그램을 비교적 쉽게 구성할 수 있다.

  • The fault location algorithm based on stationary wavelet transform was developed to locate the fault point more accurately. The stationary wavelet transform(SWT) was introduced instead of conventional discrete wavelet transform(DWT) because SWT has redundancy properties which is more useful in noise signal processing. In previous paper, noise cancellation technique based on the correlation of wavelet coefficients at multi-scales was introduced, and the efficiency was also proved in full. In this paper, fault section discrimination and fault location algorithm using noise cancellation technique were tested by ATP simulation on real power cable systems. From these results, the fault can be located even in very difficult and complicated situations such as different inception angle and fault resistance.

  • A new piece of test equipment, the slurry wear tester (SWT), was proposed in this study to evaluate the wear behavior of rubber vulcanizate in environmental contact with slurry. Natural rubber (NR) and chloroprene rubber (CR) were chosen as the basic matrices to test the slurry wear. The fluids used to fill the chamber of the SWT were 35% HCl and NaCl solution. The Akron abrasion test was used for comparison with SWT. According to the results of the Akron abrasion test, CR vulcanizate abraded more rapidly than NR vulcanizate under same test condition. It was found that the hysteresis of rubber was key factor contribute to the wear behavior. However, the slurry wear rate of the NR and CR vulcanizates did not change significantly, even with changes in the concentration of acid and the immersion time in both HCl and NaCl solutions; the fluid decreased the friction between the abrasive paper and the specimen. It also reduced the heat generated from repeated deformation and wear debris at the surface of the SWT's abrasion arm. Thus, these phenomena affected the wear behavior of rubber vulcanizate and caused different results in the conventional Akron abrasion test. This outcome could have resulted in an incorrect analysis if the slurry wear behavior of the rubber vulcanizate was estimated by the conventional abrasion tests, which are operated under dry conditions.

  • Effects of the Seokchangpo-Wonji-Tang on recovery from disorder of stomach, liver and mental-faculty in alcoholism were studied using male Sprague-Dawley rats. The rats were assigned into 4 groups; normal, control and Seokchangpo-Wonji-Tang(SWT) group. Control group administered ethanol(25 v/v %) at a dose 3g/kg, while SWT group administered 50mg/kg of SWT 30min before treating same dose of ethanol as control group for 10 days, orally. The gastric ulceration and also GOT and GPT activities in rats were checked, and all groups were subjected to trials of straight channel on the 1st day and to those of multiple T-maze during the following 3 days. The gastric ulceration, GOT and GPT activities were increased in control group, but decreased in SWT group significantly. The time required in normal group for the straight channel of the 2nd and 3rd trials was significantly shorter than that of the 1 st, while the control group showed no significance. In the time required for the multiple T-maze trials, the control group showed no significance. But in the straight or T-maze trials, the SWT group showed significant decrease in the time required against the control group.

  • In order to evaluate the prevention effect of Sunkiwhajung-tang (SWT) which has been used as a traditional prescription for the treatment of digestive disease in Korea on the gastric ulcer induced by indomethacin in rats, the changes of number and size of ulcerative lesions, parietal, chief, Grimelius and Serotonin-positive cells in the peri-ulcerative tissues were detected with histological examinations of ulcerative and peri-ulcerative lesions after oral injections of SWT extracts (125, 250 and 500 mg/kg, respectively). SWT prevented to a great extent the expected indomethacin-induced elevation in hemorrhagic ulcerative lesions, the number and size of ulcerative lesions, and the number of parietal cell, chief cell, Grimelius-positive cells and Serotonin-positive cells in the peri-ulcerative lesions in a dose dependent manner. These results provide a story evidence that SWT produced an protective effect on gastric ulcer induced by indomethacin. Determination of the specific mechanisms involved in the protective effect of SWT on the gastric ulcer will require additional study.

  • Effects of Ssang Wha Tang (SWT), a blended Chinese traditional medicine, on the pharmacokinetics of sulfobromophthalein (BSP) were studied in the rats. BSP was administered via portal vein to the control and the SWT-treated rats. The in vitro distribution of BSP to blood cells and the hemato-physiological conditions, liver weight, GOT. GPT activity were also examined. The systemic clearance $(CL_s)$ of BSP was increased with the administration of SWT, but no significant differences were observed in the liver weight and in vitro distribution of BSP to blood cells. These results suggest that the intrinsic clearance of free BSP of the liver is increased with the administration of SWT in the rats.

  • Migration characteristics with forms of channels and bed conditions are studied by constant-radius curve (CRC), sine-generated curve (SGC) and small-wave theory (SWT) method. For channels which are meandering and of which bed conditions are of coarse materials, transverse bed slope, depth and velocity distributions are predicted by CRC and SGC method, and the results are compared with measured field data, And for fine bed-materials of the sinuous channels, lateral and downvalley migration rates are computed by SWT method. It is confirmed from this investigation that transverse mass-flux factor plays significant roles in determining of magnitude and direction of meander migration.
