  • This study is about the correlation of pain strength between Oswestry Disability Index and Hendler 10-Minute Screening Test in the patient of low back pain. The subject were 66, in and out patient who had recieved physical therapy on low back pain in several hospitals at Seoul and Kyungkido. during July 5.-August 27. 1999 1. The average score of Oswestry Disability Index was $24.06{\pm}8.16$ and that of Hendler 10-Minute Screening Test was $24.82{\pm}4.31$. 2. The Pearson's R score between each questionnaires of Oswestry Disability Index and pain strength was .5692. p<0.0001. So it is very high. But, that between each questionnaires of Hendler 10-Minute Screening Test and pain strength was not significant.. 2261 p<0.05 3. The Pearson's R score between Pain strength of Oswestry and person care was .3391, sex life was .3756, social life was .4637 (p<0.005) and that between Pain factor of Hendler, pain area of Hendler and sleeping(4358), sex(.6198), position change(2767), (p<0.005). So it is significant. 4. The categories where we could see the correlation between Pain strenth of Oswestry and Hendler each questionnaires were sleeping(.3222), sex(5524), position change(4291). (p<0.005).

  • National-wide and/or large scale sample surveys generally use complex sample design. Traditional Pearson chi-square test is not appropriate for the categorical complex sample data. Rao-Scott suggested an adjustment method for Pearson chi-square test, which uses the average of eigenvalues of design matrix of cell probabilities. This study is to compare the efficiency of Rao-Scott first order adjusted test to Wald test for homogeneity between two populations using 2009 Gyeongnam regional education offices's customer satisfaction survey (2009 GREOCSS) data. The 2009 GREOCSS data were collected based on stratified three-stage cluster sampling with probability proportional to size. The empirical results show that the Rao-Scott adjusted test statistic using only the variances of cell probabilities is very close to the Wald test statistic, which uses the covariance matrix of cell probabilities, under the 2009 GREOCSS data based. However it is necessary to be cautious to use the Rao-Scott first order adjusted test statistic in the place of Wald test because its efficiency is decreasing as the relative variance of eigenvalues of the design matrix of cell probabilities is increasing, specially more when the number of degrees of freedom is small.

  • Background: Passive straight leg raising (PSLR) is the common clinical test to measure of hamstring muscle length. Hip flexion angle contributes to change the lumbopelvic rotation during PSLR. Pressure biofeedback unit (PBU) is commonly used to detect lumbopelvic movement during lower limb movements. Thus, there may be the relationship between pressure of PBU and lumbopelvic motion during PSLR. Objects: The objective of this study was to determine the relationship between pressure of PBU and lumbopelvic motion during PSLR. Methods: Thirty two subjects participated in this study. A three-dimensional motion analysis system were used to measure the lumbopelvic angle during PSLR, while recording the pressure of PBU according to angle of PSLR by 10 degree increments. Pearson product moment correlations and linear regression analysis were used to describe the relationship between variables. Results: The results showed that there was a significant relationship between the lumbopelvic and angle of PSLR (Pearson's r=.83, p<.05), between the pressure of PBU and angle of PSLR (Pearson's r=.75, p<.05), and between lumbopelvic motion and pressure of PUB (Pearson's r=.83, p<.05). Linear regression equation using lumbopevic angle as an independent factor was as follows: Pressure of PBU = 47.35 + (2.55 ${\times}$ angle of lumbopelvic motion) ($R^2=.69$, p<.05). Conclusion: Results of the present study indicate that pressure of PBU can be used to indirectly detect the amounts of lumbobevic motion during muscle length test or stretching of hamstring.

  • The research interprets the principles of sampling error design for quality statistics models such as hypothesis test, interval estimation, control charts and acceptance sampling. Introducing the proper discussions of the design of significance level according to the use of hypothesis test, then it presents two methods to interpret significance by Neyman-Pearson and Fisher. Second point of the study proposes the design of confidence level for interval estimation by Bayesian confidence set, frequentist confidential set and fiducial interval. Third, the content also indicates the design of type I error and type II error considering both productivity and customer claim for control chart. Finally, the study reflects the design of producer's risk with operating charistictics curve, screening and switch rules for the purpose of purchasing and subcontraction.

  • Purpose: To evaluate the correlation between colon transit time (CTT) test value and initial maintenance dose of polyethylene glycol (PEG) 4000 or lactulose. Methods: Of 415 children with chronic functional constipation, 190 were enrolled based on exclusion criteria using the CTT test, defecation diary, and clinical chart. The CTT test was performed with prior disimpaction. The laxative dose for maintenance was determined on the basis of the defecation diary and clinical chart. The Shapiro-Wilk test and Pearson's and Spearman's correlations were used for statistical analysis. Results: The overall group median value and interquartile range of the CTT test was 43.8 (31.8) hours. The average PEG 4000 dose for maintenance in the overall group was $0.68{\pm}0.18g/kg/d$; according to age, the dose was $0.73{\pm}0.16g/kg/d$ (<8 years), $0.53{\pm}0.12g/kg/d$ (8 to <12 years), and $0.36{\pm}0.05g/kg/d$ (12 to 15 years). The dose of lactulose was $1.99{\pm}0.43mL/kg/d$ (<8 years) or $1.26{\pm}0.25mL/kg/d$ (8 to <12 years). There was no significant correlation between CTT test value and initial dose of laxative, irrespective of the subgroup (encopresis, abnormal CTT test subtype) for either laxative. Even in the largest group (overall, n=109, younger than 8 years and on PEG 4000), the correlation was weak (Pearson's correlation coefficient [R]=0.268, p=0.005). Within the abnormal transit group, subgroup (n=73, younger than 8 years and on PEG 4000) correlation was weak (R=0.267, p=0.022). Conclusion: CTT test value cannot predict the initial maintenance dose of PEG 4000 or lactulose with linear correlation.

  • The purpose of this study was to investigate (1) children's field dependence by age and sex, (2) children's interpersonal problem solving ability by age, sex, and contextual factors, (3) children's interpersonal problem solving ability by field dependence. The subjects were 120 five-, seven-, and nine-year-olds. Children's field-dependence was measured with the Children's Embedded Figures Test (CEFT). Children's interpersonal problem solving ability was measured with the Preschool Interpersonal Problem Solving Test (PIPS Test). Statistical methods adopted for data analysis were frequencies, percentiles, means, standard deviation, t-test, oneway ANOVA. $Scheff{\acute{e}}$ test and Pearson's correlations. Major findings were that (1) The older children were more field-independent than the younger ones (2) The older children suggested more problem solving methods and higher-level problem solving strategies than the younger ones. (3) Children suggested higher-level problem solving strategies in contexts involving familiar as opposed to unfamiliar participants and contexts involving children as opposed to adults. (4) 9-year-olds' field-independence was positively associated with interpersonal problem solving ability.
