Summary: This White Paper details the status of hip and knee arthroplasty care in Germany. Hip and knee replacements are amongst the most frequently performed procedures and usually become necessarily due to age-related wear of the joint, osteoarthritis and fractures of the femoral neck. In light of demographic change, demands with regard to standards of care and the procedures are likely to rise. This book addresses people involved in shaping and representing the healthcare system from a variety of fields including medical professions, health insurances and health sciences as well as journalists and patient representatives.

The purpose of this study is to discover a design methodology for User Centered Design (UCD) Innovation. This paper focuses on paper prototype method for user evaluation and design. After proposing an approach to utilize paper prototype method, author proposed detail approach based on UCD process. In case study, author utilized this method for design education of design course on university. As a result, author received several innovative ideas from UCD view point. [ABSTRACT FROM AUTHOR]

As sort of traditional paper process machinery equipments, paper cutting machines are developing rapidly in hydraulic, digital display and computer control machines. But a great number of products of the paper cutting machines in the market are that the pressing paper units are controlled by hydraulic drive and cutting paper units still adopt mechanical driven by worm wheel and worm. These kinds of paper cutting machines have many disadvantages, such as: complex structure, low driven efficiency and low availability factor of hydraulic system and so on. One type of the paper cutting machine with fully hydraulic system both in pressing paper and cutting paper units is studied in detail. The hydraulic system element circuit are delivered and analyzed in detail. The loading and working condition of hydraulic system are also analyzes and calculated; the main parameters of performing elements including the power of motor are confirmed as well.
