Objective: The purpose of this study is to compare the effects of extracorporeal shock wave therapy (ESWT) and injection therapy through qualitative and quantitative analysis by synthesizing randomized controlled trials (RCTs) conducted on patients with various shoulder diseases. Design: A systematic review and meta-analysis of randomized controlled trials Methods: This review conducted a literature search through international electronic databases in January 2023 to compare the effects of ESWT and injection therapy. Qualitative analysis was performed as a risk of bias tool, and quantitative analysis was synthesized with a random effect model to show the effect size as a standardized mean difference (SMD). Results: Five RCTs involving 298 individuals with shoulder disorders were included in this systematic review and meta-analysis. ESWT showed a moderate effect on pain (SMD=-0.44; 95% CI, -0.95 to 0.06) and a large effect on shoulder function (SMD =-0.81; 95% CI, -1.70 to 0.07) than injection therapy. A significant difference was found in the shoulder range of motion, showing a large effect size (SMD=1.50; 95% CI, 0.58 to 2.43). Conclusions: When considering treatment options for the management of patients complaining of shoulder disorders, it is appropriate to recommend ESWT first rather than injection therapy to increase the range of motion of the joint. In addition, ESWT is safe for pain control and shoulder function improvement, and a positive prognosis could be expected.

Today's health care environment is rapidly changing and nurse administrators' transformational leadership needs to practice in nursing organization to achieve organizational objectives. Transformational leadership is related to the job satisfaction, productivity, and organizational commitment. This study investigated the effect of transformational leadership and carreer characterics on nurses' organizational commitment. The sample for this study consisted of 594 nurse from 8 large Korean hospitals. The factor analysis Cronbach's alpha analysis, Pearson correlation analysis, multiple regression analysis and hierarchical multiple regression analysis were used for the statistical method. The results of this study were found that (1) charisma dimension of transformational leadership has positive influence on nurses' organizational commitment; but another two dimensions (intellectual stimulation and individualized consideration) did not showed significant effect on organizational commitment (2) nurses' career characteristic(age, marital status, education level. work duration, status) moderated the effect of transformational leadership on organizational commitment.

This study is to investigate the effect of C factor errors on the analysis of water distribution systems. For this purpose, an artificial distribution network and a real distribution network were selected as the study networks. Results are as follows. 1. The C factor of a pipe which has small velocity didn't give significant effect on the analysis of a water distribution system. 2. The effect of decreased value of C factors give more influence on the analysis of water distribution systems than that of the increased values. 3. For the C factor calibration, errors of the residual water heads as well as those of the head losses should be considered together. 4. In the analysis of water distribution systems, changes of C factors can give influences only on the nodes which locate behind the pipe. Therefore, this characteristics should be considered in the selection of nodes for the measurement of water heads.

A comparative study on the turbulent flaw simulation and the potential flaw analysis has been performed. A law Mach number preconditioned Navier-Stokes solver, using the multi-block grid method and a panel method based on the velocity potential, have been developed and validated by comparison to the experimental data. The present numerical analysis methods are applied to the ground effect problem around the NACA 4412 airfoil. It has been confirmed that the potential flaw analysis on the ground effect, using the image method, is consistent, to some degree, with the viscous calculations for high Reynolds number flows.

The purpose of this Study is to present the tasks and means of improving the operational system of public culture and arts institutes in the future on the basis of the analysis of the effectiveness of operation of public culture and arts institutes. The summary of the results of analysis in this Study is as follows: Firstly, it was found that the factor variables that impart effect on the operation of public culture and arts institutes included (1) artistic value, (2) convenience and (3) organizational management, while the performance variable of public culture and arts institutes was (4) operational performance. Secondly, in the analysis of the structure that explains the operational effects of public culture and arts institutes, convenience and organizational management were found to impart effects on the operational performances. However, artistic value was found to have no effect on operational performances. Therefore, these results of analysis imply that organizational management and convenience, rather than artistic value, need to be fortified in order to elevate the operational performances of public culture and arts institutes.

The purpose of this study was to examine the effect of subjective norms on customers' intention to engage in voice of dissatisfaction responses, the effect of subjective norms on attitude, and the mediating effect of attitude on the relationships between subjective norms and customers' intention to engage in voice of dissatisfaction responses. The simple regression analysis is used in order to estimate the effects of subjective norms on customers' intention to engage in voice of dissatisfaction responses and attitude. The mediated regression analysis is used in order to estimate the mediating role of attitude of the effect of subjective norms on customers' intention to engage in voice of dissatisfaction responses. Results of the study demonstrated that the inclusion of perceived behavioral control did significantly improve the predictability of the voice of dissatisfaction response intentions. Furthermore, the mediating analysis indicated that the influence of subjective norms was mediated by mediator. In the contests of voice behavior, the effect of subjective norms on intention was mediated by attitude.
