BEHAVIOR OF FREE-ACCESS FLOOR DURING SEISMIC EXCITATION BY THREE-DIMENSION INPUT WAVE AND HORIZONTAL ONE-DIMENSION INPUT WAVE: Fundamental study on evaluation method for seismic resistance of free-access floor

Abstract Background : In pandemic times where the “lockdown strategy” has been adopted, the use of innovations using technological resources such as the creation of instruments that can replace traditional teaching-learning methods in the training of health professionals is essential. The aim of this study was to develop and evaluate the usability of a realistic interactive simulation computer system using three-dimensional imaging technology and virtual reality with free-access computational tools available on the web. Methods : the development of a prototype (OSCE 3D) was based on the steps used for the construction of simulation software of a "Serious Game". An experimental phase was carried out to assess usability, through a questionnaire based on the System Usability Scale. The study was approved by the Research Ethics Committee of the institution and all patients signed the Informed Consent Form. Results : a total of 39 undergraduate medical students from the 6th semester of a private university center of northeast do Brazil voluntarily participated in the evaluation of the OSCE 3D. The usability evaluation presented a mean score of 75.4 with a margin of error of 3.2, considered a good usability according to the literature. Conclusions : this work allowed the development of a low-cost prototype, using a three-dimension realistic simulation system for OSCE assessment stations. This product, even in the prototype phase, showed good usability.

Assembly Deviation

Evaluation method of assembly yield in three-dimension single-station assembly process is presented based on Number-Theoretical Net (NT-net) and 3DCS. Firstly, based on the analysis of fixture deviation affect assembly deviation under arbitrary layout, the three dimensional single-station assembly deviation model under arbitrary layout is developed. Then, the principle of generating good lattice point (GLP) based on NT-net method is introduced. Afterwards, taking fixture locating variations which are sampled using NT-net method for input vectors, the samples are substituted into assembly deviation model of dimension variation propagation in single-station assembly processes to get output vectors. The statistics for qualified sample is accomplished, after comparing output vectors with the variations of measuring points on component. Assembly yield in three-dimension single-station assembly processes is gained when qualified sample divided by total sample. Finally, a real case in sheet metal assembly is given as an example to calculate the assembly yield in three-dimension single-station assembly processes. The result is validated by 3DCS.
