The 3D printing selective laser sintering (SLS) and stereo lithography apparatus (SLA) method used for bone model production has good precision and resolution, but the printers are expensive and need professional knowledge for operation. The program that converts computed tomography digital imaging and communications in medicine (DICOM) file into STL (stereolithography) file is also expensive so requesting 3D printing companies takes a lot of time and cost, which is why they are not generally utilized in surgery. To produce bone models of fractured patients, the use of 3D imaging conversion program and 3D printing system should be convenient, and the cost of device and operation should be low. Besides, they should be able to produce big size bone models for application to surgery. Therefore, by using an fused deposition modeling (FDM) method 3D printer that uses thermoplastic materials such as DICOM Viewer OsiriX and plastic wires, this study developed 3D printing system for Fracture surgery Patients customized bone model production for many clinics to use for surgery of fracture patients by universalizing with no limit in printing sizes and low maintenance and production cost. It is expected to be widely applied to the overall areas of orthopedics' education, research and clinic. It is also expected to be conveniently used in not only university hospitals but also regular general hospitals.

This study aims to analyse the redistributive impact of the welfare state growth in Korea after 2000s and establish whether there are people excluded from the benefits of the growth. The growth of the Korean welfare state has been achieved by universalizing welfare benefits under the social insurance-centered institutions which are the legacies of the productivist/developmental welfare regime. When it comes to redistribution impacts, the welfare state growth improved inequality among old age populations to a certain degree due to the introduction of the Basic Pension. On the other hand, welfare benefits for the working poor population has hardly been improved in spite of the growing welfare state. It can be said, therefore, that low-income working-age populations have been excluded from the growth of Korean welfare state. These groups are mostly in middle-old age, unemployed or precariously employed and half of them were female householders. The exclusion of these groups from the Korean welfare state shows that the growth of the Korean welfare state was unbalanced. To include the excluded into the Korean welfare state, it is necessary to increase non-insurance social provisions, extend the range of application of the social insurances, integrate income protection, employment service, and vocational training for the working poor, and combine universal and targeted welfare benefits.
