Research of Double Circular-Arc Gear Fast Modeling Based on CATIA Secondary Development
Through the analysis of double circular-arc gear basic gear profile and the use of coordinate transformation method, this paper deduces the gear end-face equation of double circular-arc gear. With CATIA secondary development as a tool and double arc gear as the study object, accurately calculates the gear teeth curve profile and generate a double circular-arc gear one-time three-dimensional model by using the VB language programming, so as to improve design efficiency and accuracy, which lays a foundation for the strength analysis of the double arc gear, follow-up design and development of simulation, virtual assembly solid model.
Parametrization Modelling of Collimating End Surface Double Circle-arc Gear
The precise parametrization objective modelling method of collimating end surface double cirle-are gear,applying Pro/E and Program function,is introduced,which can be used to improve design efficiency and design accuracy,to provide the basic conditions for strength analysis,simulation and objective model virtual assembly etc.later design development.
From student to therapist: exploring the first year of practice.
OBJECTIVES
The transition from classroom to clinical practice challenges many health professional students. This study used a phenomenological approach to explore the lived experience of rehabilitation students during their final placement and first year of practice.


METHOD
Students (n = 6) in occupational therapy and physical therapy wrote reflective journals every 2 weeks during their final fieldwork placement and first year of practice. The researchers independently analyzed the journals for common themes. An independent peer completed a blind analysis of two journals. Data were also compared with published first-person accounts of novice practitioners.


RESULTS
The lived experience of the first year of practice included four consecutive stages: Transition, Euphoria and Angst, Reality of Practice, and Adaptation. Themes from the journals included great expectations, competence, politics, shock, education, and strategies.


CONCLUSION
Recognizing the stages in the process of transition from student to therapist may assist in educational curriculum development and clinical support and supervision for new graduates. Educators need to continue to make education practice relevant while maintaining a theoretical perspective.
