Aim(s): In the current Army health care delivery system, soldiers have received primary health care from the medical company. If the symptoms get worse, they are transferred to the medical battalion or military hospital. However, the medical company has a problem in providing timely care because of the lack of medical personnel and equipment, which worsens patient conditions and reduces patient satisfaction. Therefore, we conducted a pilot project that the medical company focuses on the role of evacuation and the medical battalion reinforces functions of primary health. The purpose of this study was to compare patient satisfaction in health care before and after the pilot project. Method(s): This study was a nonequivalent control group pretest-posttest design, recruiting 82 soldiers who experienced in medical services before and after pilot projects. The patient satisfaction was investigated as in 4 criteria: accessibility, system infrastructure, care coordination, and patient-centeredness. The pilot project was conducted from September 2019 to April 2020, and the data were from January 2019 to March 2020. Result(s): The results of independent t-test showed that the soldiers evaluated the system infrastructure sector was significantly increased (p=.003) while the accessibility was decreased (p=<0.001) after the pilot project compared to before the pilot project. The care coordination and the patient-centeredness were increased as well after the pilot project, but their figures were not statistically significant. Conclusion(s): This study identifies that the pilot project on improvement of medical battalion"s function has a positive impact on patient satisfaction. In addition, it suggests that strengthening strategies on accessibility should be prioritized in order to expand the pilot project.
Flexibility modeling of a beam undergoing large deflection using the assumed mode method
Jeong, Sinwoo,Yoo, Hong Hee Pergamon Press 2017 International journal of mechanical sciences Vol.133 No.-
<P><B>Abstract</B></P> <P>We propose a new nonlinear modeling method to conduct the static or dynamic analysis of a flexible beam undergoing large deflection in this paper. In the proposed modeling method, we employ the in-extensible beam assumption which simplifies the expressions of strain energy and geometric constraints among deformation variables. Deformation variables are approximated using modal coordinates and quasi-comparison functions. Governing equations are derived based on the extended Hamilton's principle and used to solve various kinds of nonlinear static and dynamic analysis problems. The accuracy of the proposed modeling method is validated by comparing numerical results to those obtained with a commercial nonlinear finite element code. The efficiency and solution convergence robustness of the proposed modeling method are also compared.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A nonlinear modeling method for a beam undergoing large deflection is proposed. </LI> <LI> The assumed mode method is employed for the nonlinear modeling method. </LI> <LI> Various numerical examples for beams undergoing large deflection are solved. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>(a) Circular-path guided compliant mechanism and (b) deformed shapes of the flexible link versus β</P> <P>[DISPLAY OMISSION]</P>
