  • In this paper we introduced a new score generating function for the rank dispersion function in a multiple linear model. Based on the new score function, we derived the asymptotic relative efficiency, ARE(11, rs), of our score function with respect to the Wilcoxon scores for the generalized F distributions which show very flexible distributions with a variety of shape and tail behaviors. We thoroughly explored the selection of r and s of our new score function that provides improvement over the Wilcoxon scores.

  • Objectives To investigate clinical effects of needle embedding acupuncture treatments for chronic low back pain patients. Methods 30 patients with chronic low back pain were recruited and randomized into two groups-the embedding acupuncture group or the placebo. At baseline, the age, height, weight, visual analogue scale (VAS), Oswestry disability index (ODI) scores were measured. And surface electromyography (SEMG) data of both erector spinae at L2, L4 level were also measured on both groups and asymmetry index (AI) were calculated. The embedding or placebo acupuncture treatment was performed on the erector spinae according to SEMG values; immediately after the first evaluation and 48 hours after the first visit. After 96 hours of intervention, the VAS, ODI score and SEMG of both erector spinae were measured again. Statistical significance was determined using the Wilcoxon signed ranks test or the Wilcoxon rank sum test. Results The mean VAS, ODI score after treatment was decreased significantly compared with baseline on both groups. And the VAS, ODI score and AI of the embedding acupuncture group was more decreased significantly than the placebo (p<0.05). Conclusions The results suggest that embedding acupuncture for chronic low back pain patients was effective on the VAS pain score, ODI score and AI of the erector spinae.

  • This study was done to identify the effectiveness of a proper positioning on musculoskeletal complication on patient with Stroke by using a quasi-experimental study. A total of 18 patients were selected as a subject from June 1st to October 31th 1998 who had been hospitalized at Intensive Care Units in K medical center. A experimental group consists of 8 patients who were given proper positioning every two hours. A control group consists of 10 patients who were given traditional positioning. The collected data were analyzed by SPSS windows including $X^2$-test (Fisher's exact method), Wilcoxon Rank Sum test and McNemar test. The result of this study was summerized as follows : 1) The experimental group with proper positioning has shown lower shoulder pain score, dorsiflexion contracture score, Shoulder subluxation score and higher Range of Motion and than the control group. 2) The experimental group with proper positioning has shown lower muscle pain score and edema score than the control group, but it was not statistically significant.Therefore, proper positioning could be applied as an independent nursing intervent ion for patients on Stroke in order to facilitate rehabilitation.

  • Purpose: The purpose of this study was to investigate the degree of LUTS (Lower Urinary Tract Symptoms) and factors affecting LUTS in patients with prostate cancer. Methods: Fifty-four patients with prostate cancer participated and they completed a structured questionnaire at a hospital in Seoul. The LUTS level was measured by using the International prostate symptom score (1992) and the data were analyzed by Wilcoxon rank sum test and Kurskal-Wallis test. Results: Most subjects obtained a higher than moderate LUTS score. The participants who had a lower perceived health status and did not drink alcohol were more likely to had a lower LUTS score than other patients who had higher perceived health status and drink alcohol. In addition, eye diseases were significantly associated with the LUTS score. In LUTS, all the patients received higher IPSS-QOL (International prostate symptom score quality of life) and frequency, nocturia. Conclusion: For proper nursing care related to LUTS, nurses should focus on the factors identified when performing nursing assessments and should develop nursing intervention programs for symptoms management.
