Longitudinal analysis of the effect of academic failure tolerance on academic achievement fluctuation in medical school students / 한국의학교육

PURPOSE: Academic failure tolerance (AFT) is one of the important psychological concepts in education, but its applications in medical education are rare. Thus, the purpose of this study was to investigate the effect of academic failure tolerance on academic achievement fluctuation among medical school students using a longitudinal research design. METHODS: The subjects were 43 medical students who responded to the AFT test. This study analyzed the longitudinal data of achievement scores up to the 2nd academic year (2012–2013) among students who were divided into academic achievement improvement and decline groups. RESULTS: Comparing the improvement and decline groups' mean academic achievement fluctuation scores demonstrated that behavior and preferred task difficulty showed high scores whereas feeling scores were lower in the improvement group (p<0.05). CONCLUSION: In the improvement group, despite the higher negative feeling scores during academic failure, the students favored the more difficult subjects and were more assiduous in their studies. This will form an important basis for enhancing academic achievement among medical students.

Simulation of dynamic tests on long bones of lower limbs based on finite element model / 医用生物力学

Objective To study the failure tolerance in long bones of lower limbs under dynamic loads. Methods Based on the finite element (FE) model of lower limb for Chinese people, the dynamic three-point bending test on the femur, tibia, leg and thigh was conducted , and the FE model was validated against the cadaveric experiment. Results The force-displacement curves between FE simulation and cadaveric experimental results for bending tests were correlated. The contact forces on femur, tibia, thigh and leg with failure tolerance were 4.29, 3.94, 4.81 and 4.086 kN, respectively，and the displacements from the impactor were 17.78, 34, 52.1, and 47.06 mm, respectively. The simulation results were correlated well with those in dynamic cadaveric experiments. Conclusions This study validated the effectiveness of the FE model, which would lay a good foundation for the further research on validation of FE model of knee joint and whole lower limb, and provide the theoretical references for the protection of pedestrians in crashes.
