BackgroundThe objectives of the present study were to examine the intra- and inter-operator reliability of the MyotonPRO device in quantifying the stiffness of the Achilles tendon and the device’s ability to examine the modulation in stiffness of the Achilles tendon during ankle joint flexion.Material/MethodsTwenty asymptomatic participants (10 males and 10 females; mean age: 25.0±3.1 years) were recruited for this study. The stiffness of the Achilles tendon was quantified using the MyotonPRO device.ResultsThe results revealed excellent intra- and inter-operator reliability for quantifying Achilles tendon stiffness with the ankle joint in a neutral position and detected a 13.9% increase in stiffness of the Achilles tendon between 0° and 30° of ankle joint flexion. The minimal detectable change (MDC) in tendon stiffness was 45 Newton/meter (N/m).ConclusionsOur findings indicated that the MyotonPRO device is a feasible method to quantify the stiffness of the Achilles tendon and monitor its changes. Thus, it is an essential tool to use to examine the modulation in the stiffness of the Achilles tendon due to pathology or interventions for future studies.

Three kinds of pipeline steel with different microstructures were fabricated by varying cooling schedules during thermo-mechanical controlled processing (TMCP). Charpy impact property of the pipeline steels were obtained, and the fracture and crack-arrest mechanisms were further studied. The results indicated that the steels were classified into two kinds according to their microstructures, the mixture of acicular ferrite (AF), quasi-polygonal ferrite (QF), granular bainite (GB) and small fraction of degenerate pearlite (DP), and the mixed microstructure of AF and GB, respectively. The processed steel with microstructure of AF and GB exhibited more excellent low-temperature toughness and crack-arrest properties with upper shelf energy of ~281 J and energy transition temperature of ~-76°C. The mixed microstructure (AF + GB) possessing smaller effective grain size hindered the propagating of crack and consumed large amount of energy during fracture. The effective grain size of microstructure was the dominant factor controlling low-temperature toughness and crack-arrest properties of pipeline steel, which increased the high-angle boundary length per unit area and further increased the crack propagation energy during fracture.

With the strategy implementation of rising in central of China, Jiangxi Province is entering a new development in historical period. As the important city of red revolutionary old section and city zones of Beijing-Kowloon, Ganzhou obtains the new development opportunity. As an important city in Ganzhou, Nankang is also integrated into urban district of Ganzhou and it brings vitality to greatly accelerate development of Ganzhou. Its private economy is active and local financing demand is very strong. Therefore, we should establish financial center and based on Ganzhou, the planning and strategy faces with China emerges as times requires. The urban design of Nankang financial center aims at optimizing function and system as well as promoting economic development, enhancing its space quality, modeling city image and optimizing city ecological environment.

This paper based on the best architecture universities education concept, through the analysis of the architecture education mode, put forward the current architectural education reform and development directions. From the perspective of curriculum practice, probes into the new mode of curriculum and education, enhance the comprehensive ability and creative thinking of students; Reference to CRIT rating chart patterns, join in the concept of "workshop", Create local and broader academic building information platform, provides the domestic architectural education improvement ideas.

Based on the knowledge and understanding of interaction design, we Trigger the architectural design concept. The target is introducing the concept of interaction design to architectural design. Using the interaction design methods and ways of thinking, expanding architectural design ideas, improving the design approach and further explore the interaction design about the people and buildings, as well as the object and buildings.
